Humidifier circuit board
A humidifier is a household appliance that increases room humidity. The humidifier can humidify the designated room, or it can be connected to a boiler or central air conditioning system to humidify the entire building. The development of the humidifier industry in China has a history of nearly 20 years. After years of popularization of air quality concepts, product research and development, and market cultivation, the function and role of humidifier, a relatively unfamiliar small home appliance product, has gradually been accepted.If you want to order PCB product, please check and custom your order online.Working principle of humidifier Humidifiers are mainly divided into two types: household humidifiers and industrial humidifiers.Ultrasonic humidifier uses ultrasonic high-frequency vibration 1.7MHZ frequency, atomizing water into 1-5 micron ultrafine particles, can refresh the air, improve health and create a comfortable environment.According to experts, the advantages of ultrasonic humidifiers are high humidification intensity, uniform humidification, and high humidification efficiency; energy saving, power saving, power consumption is only 1/10 to 1/15 of the electric humidifier; long service life, automatic humidity balance , Automatic protection without water; also has the functions of medical atomization, cold compress bath surface, cleaning jewelry and so on.Direct evaporation humidifiers are also commonly referred to as pure humidifiers. Pure humidification technology is a new technology just adopted in the field of humidification. The pure humidifier removes calcium and magnesium ions in the water through molecular sieve evaporation technology to completely solve the "white powder" problem.Heat evaporative humidifier is also called electric humidifier. Its working principle is to heat the water to 100 degrees in the heating body, generate steam, and send the steam out with a fan. Therefore, the electric heating humidifier is the simplest humidification technology. The disadvantage is that the energy consumption is large, it cannot be dried, the safety factor is low, and the heater is easy to scale. The market outlook is not optimistic. Electric humidifiers are generally used in conjunction with central air conditioners, and are generally not used separately.Compared with the above three, the electric heating humidifier has no "white powder" phenomenon in use, and the noise is low, but the power consumption is large, and the humidifier is easy to scale; the pure type humidifier has no "white powder" phenomenon and does not scale, and the power is small , With air circulation system, can filter the air and kill bacteria.Ultrasonic humidifier has high and uniform humidification intensity, low power consumption and long service life. It also has the functions of medical atomization, cold compress bath surface, and jewelry cleaning. Therefore, ultrasonic humidifiers and pure humidifiers are also recommended products of choice.Five characteristics1. The box body is made of stainless steel, and the movement is atomized.2. The positive electrode is integrated, and a single movement can independently replace the chip.3. No mechanical operation, with water level protection switch, reliable operation.4.

Electric kettle circuit board
The working principle of the electric kettle is that the steam generated when the water is boiling deforms the bimetallic sheet of the steam temperature-sensing element. This deformation pushes the power switch to power off through the principle of lever. The power off is not self-resetting, so the kettle will not reheat automatically after power off. The electric kettle was born in Chicago in 1891. With the development of science and technology, fast, safe, convenient, and full use of energy have gradually become the main characteristics of kettles, and British tea lovers have fallen in love with it ever since. In the 21st century, it has become a global bestseller. The electric kettle uses steam intelligent induction temperature control, which has the functions of automatic power off after water boiling and anti-dry burning power off. With the needs of life, the current electric kettle is also developing in the direction of multi-function, such as leak-proof, anti-scald, water lock, etc. The electric kettle has the advantages of fast heating speed, good heat preservation effect, strong filtering function and many styles.If you want to order PCB product, please check and custom your order online.Electric kettle composition Most of the kettles with heat preservation function have two heating pipes, and one heat preservation heating pipe is independently controlled by the heat preservation switch, which allows the user to control whether to keep warm. Insulation power is generally below 50W, usually consumes no more than 0.1 kWh for one hour.Key components: The key component of the electric kettle is the thermostat. The quality and service life of the thermostat determine the quality and service life of the kettle. The thermostat is divided into: simple thermostat, simple + jump thermostat, waterproof, anti-drying thermostat. Consumers are advised to buy water-proof, dry-burning thermostat electric kettles.Other components: In addition to the key temperature controller, the composition of an electric kettle must include these basic components: kettle opening button, kettle top cover, power switch, handle, power indicator, heating site, etc.Working principle of electric kettleAbout 5 minutes after the electric kettle is connected to the power supply, the steam deforms the bimetallic strip of the steam temperature-sensing element, and opens the switch contact to disconnect the power supply. If the steam switch fails, the water in the pot will continue to burn until the water is dried, and the temperature of the heating element rises sharply. There are two bimetallic plates at the bottom of the heating plate. The temperature will rise sharply due to heat conduction, expand and deform, and break. Turn on the power. Therefore, the safety protection device of the electric kettle is very scientific and reliable. This is the principle of triple safety protection of electric kettle.Wanna know PCB project?

Electric heater circuit board
Electric heaters use electrical energy as the main energy source, and use resistance heating, induction heating, arc heating, electron beam heating, infrared heating, and medium heating to heat the human body through direct contact, warm air convection, and far infrared radiation.If you want to order PCB product, please check and custom your order online. Main functions of electric heater1. "Intelligent temperature control function" It consists of two parts, one is the temperature sensing unit and the other is the control unit. It senses the indoor temperature through its own temperature-sensing unit, and then makes the operation of turning on and off intelligently through the control unit, without human control. You only need to set the temperature value. In addition to the convenience of this feature, it can also effectively save power.2. "Negative ion function" The ion particles in the air are divided into positive ions and negative ions. Normal bacteria, dust, and toxic and harmful gases all carry positive ions. After adding the negative ion function, a large amount of negative ions are produced, which are actively combined with positive ions carrying materials such as bacteria, thereby effectively reducing indoor bacteria, toxic and harmful gases, and purifying indoor air.3. "Humidification function" Because the indoor temperature rises after using heating, a certain amount of water will be lost, so the humidification function can effectively make up for the moisture required by the human body. Air humidity is also an important indicator of environmental comfort.4. "Reservation and timer function" reservation is to turn on automatically according to the specified time, and timing is to turn off according to the specified time.5. "Remote control function" Generally speaking, those with remote control function have intelligent temperature control function.Type of heater PTC heaterPTC is an abbreviation for a ceramic electric heating element. It uses a fan to blow air through the PTC electric heating element to force convection, which is the main heat exchange method.The internal thermostat is installed, and when the tuyere is blocked by the fan, it can power off by itself. Some also have the function of automatic power off when tilting to the ground. That is, when the heater is tilted or overturned, it can cut off the power supply by itself. The output power of the PTC heater is 800-1200 watts, and the temperature can be adjusted at will.Advantages: Soft air supply during work, fast temperature rise, automatic thermostat function, PTC components generally have waterproof function, small size, can be used in the bathroom.Disadvantages: low power, can only be used in a small range. If you blow on the same place for a long time, the human skin will feel uncomfortable. Moreover, if it is not cleaned in time for a long time, the bacteria on the heater will be accelerated into the air and become a health risk. In addition, the power of the heater is generally relatively small, and the noise when turning on the power is also a headache.Convection heaterThe upper part of the heater cover is the air outlet, and the bottom is the air inlet. After energization, the air around the heating tube is heated up and flows out of the air outlet, and the surrounding cold air enters and replenishes from the air inlet. Such repeated cycles increase the indoor temperature. When the inlet and outlet are blocked or the ambient temperature is too high, the temperature control element will automatically cut off the power of the electric heating tube. This electric heater uses about 800 watts of power, and the power can also be adjusted by increasing or decreasing the number of electric heating tubes connected.Advantages: The electric heater has high safety performance and quiet operation.Disadvantages: Slow temperature rise and a substantial drop in ambient humidity.Electric heating heaterAlso called oil-filled electric heater. This type of electric heater is filled with a new type of thermal oil. When the power is turned on, the thermal oil around the electric heating tube is heated, and then the heat is dissipated along the heat pipe or the flake. When the oil temperature reaches 85 ℃, its temperature control element will automatically power off. This type of electric heater thermal oil does not need to be replaced and has a long service life. The selling price is generally between 400 and 500 yuan. It is suitable for use in living rooms, bedrooms, aisles and families with elderly and children. It has the advantages of safety, hygiene, dust-free and tasteless. The disadvantages are slow heat dissipation and high power consumption. There are 7 pieces, 9 pieces, 10 pieces and 12 pieces of oil cooling fins. The power can be adjusted by selecting the number of cooling fins. The power used is about 1200 watts.Electric film heaterThe hot air duct structure is adopted, the heat transfer method is enhanced convection, the hot start speed is fast, and the air outlet temperature can reach more than 100°C within 3 minutes.Advantages: The electric film does not oxidize itself when heated, so the service life can be 100,000 hours, and has the characteristics of small size and beautiful appearance. It belongs to the replacement product of the electric heater family.Disadvantages: rapid cooling after power off.The shape is relatively thin, similar to the general shape of an LCD TV. This type of heater heats up quickly, and it is easy to cool quickly after a power failure. High temperature far infrared radiation heaterA surface radiant panel of a photocatalytic coating composition is used, which is heated by an armored electric heating tube, and the electrical energy is converted into heat energy, and then the thermal energy is converted into far infrared rays through the radiant panel. The radiation zone is heated evenly, and the entire system is mainly heated by far infrared radiation.Advantages: No heat transfer through convection, almost no effect on air humidity, high power, 1500w to 4000w visible on the market, high comfort, uniform heating in fixed areas, only heating the active area, short time use is faster and power saving, can Use outside the window.Disadvantages: fixed wall construction and installation, part of the power must be installed using lead wires.Wanna know PCB project?

Electric fan circuit board
The electric fan is a household appliance that uses a motor to drive the fan blades to accelerate the circulation of air. It is mainly used to cool the heat and circulate the air. Widely used in homes, classrooms, offices, shops, hospitals and hotels.If you want to order PCB product, please check and custom your order online.The fan is mainly composed of components such as fan head, blade, net cover and control device. The fan head includes a motor, front and rear end covers, and a shaking head air supply mechanism. The main components of the electric fan are: AC motor. Its working principle is: the energized coil is forced to rotate in the magnetic field. Electrical energy is converted into mechanical energy, and due to the resistance of the coil, it is inevitable that part of the electrical energy will be converted into thermal energy.The common household electric fan is essentially an axial fan, that is, the flow direction of the wind is parallel to the rotation axis of the fan blade.Working principle of electric fan In addition, DC motors, DC brushless motors and other low-power motors are increasingly used in small fans. When the electric fan works (assuming that there is no heat transfer between the room and the outside), the indoor temperature not only does not decrease, but increases. Let's analyze the reason for the temperature increase: when the electric fan is working, because there is current flowing through the coil of the electric fan, the wire is resistive, so heat will inevitably be generated and the temperature will naturally rise. But why do people feel cool? Because there is a lot of sweat on the body surface, when the electric fan works, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat", so people will feel cool.Wanna know PCB project?

Dehumidifier circuit board
Dehumidifier is also known as dehumidifier, dehumidifier, dehumidifier. The dehumidifier belongs to a small member of the refrigeration and air conditioning family. At present, the main production areas of global dehumidifiers are concentrated in Italy, Japan and Taiwan, China. China's position in the global dehumidifier market is not significant. In particular, household dehumidifiers have always been export-oriented, but have just been recognized by Chinese consumers.After the treated air is sucked in by the fan, it is filtered by an air filter, and then cooled and dehumidified on the cooled evaporator, condensing excess water vapor in the air into water, so that the air moisture content is reduced, because the dehumidified condensate is taken away Part of the heat and humidity will reduce the temperature of the air. In order to make the temperature and humidity of the air suitable, the unique structure of the dehumidifier causes the dehumidified air to be heated and heated by the condenser, thereby increasing the ambient temperature and greatly improving the dehumidification effect of the dehumidifier.If you want to order PCB product, please check and custom your order online.Working principle of dehumidifier 1. The manufacturing of the dehumidifying wheel is made of ceramic fiber paper with a temperature resistance of 500°C or more. After the honeycomb wheel is made by a molding machine, it is coated with silica gel between the ceramic fibers, so the dehumidifying wheel will not burn and Deliquescent and other issues. Since its dehumidification function uses physical rather than chemical action, it will not produce any harmful chemical substances.2. The dehumidification principle of the rotary wheel dehumidifier is to use the silica gel coated on the rotary wheel to physically adsorb the water in the air on the porous synthetic silica gel, and then in the regeneration zone of the rotary wheel, it will be adsorbed on the silica gel. The water vapor in the hole is heated and vaporized to the inlet of the AC heat exchanger to form high-temperature and high-humidity air. When it then passes through the heat exchanger that has been cooled by the indoor cold and humid air, the condensed water is discharged due to the difference in dew point.Industry use The dehumidifier is developed for the damp and harsh ring mirror, which can not only effectively improve the humid life and production environment to achieve an ideal state, but also remove mold caused by the humid environment. By operating the dehumidifier, the moist moisture and The removal of suspended particles makes the air dry. It is also an air cleaner. Household dehumidifiers and industrial dehumidifiers are widely used in all aspects of production and life. Create a comfortable, dry and quiet modern living space for users.Principle of defrosting dehumidifierWhen the compressor dehumidifier is used in a relatively low temperature environment (generally below 10 degrees Celsius), it will cause frost in the dehumidifier heat exchange system, and this process is inevitable, so the compressor dehumidifier is at ambient temperature Under low conditions, it will enter the defrost state regularly.At this time, the dehumidifier will first stop the compressor, and use the evaporator heating wire (part of the heat exchange system) to heat the heat exchange plate temperature, and then output through the fan to produce a defrosting effect.This time-consuming needs to be determined by the ambient temperature. The lower the ambient temperature, the longer it takes. During the defrosting process, the compressor-type dehumidifier cannot perform dehumidification work, so for low-temperature environments, the compressor-type dehumidifier dehumidifies The effect is not ideal.If it is a dehumidification environment with a low ambient temperature, you can choose a new type of wheel dehumidifier.Wanna know PCB project?
