The above-mentioned air heater provides an air heater with less running noise by optimizing the airflow duct. However, the wind speed and temperature of such air heaters are generally not adjustable as needed, and it is difficult for users to set the air heater to a suitable wind speed and temperature according to the conditions of the use environment.

[0006] Furthermore, the circuit module includes a power conversion circuit, which includes an electrically connected rectifier bridge, a power management chip and a voltage regulator chip, and the power conversion circuit is electrically connected to the electric heating module, the servo fan and the humidification module.

[0007] Furthermore, a first MOS switch circuit is electrically connected between the power conversion circuit and the humidification module, and a second MOS switch circuit is electrically connected between the power conversion circuit and the servo fan.

[0008] Furthermore, the main control chip is electrically connected to a temperature sensor, and the temperature sensor is arranged in front of the electric heating module.

[0028] like Figures 1 to 5 As shown, this embodiment provides a temperature and speed regulating humidifying heater, including a heater body 1, a circuit module and a humidifying module 5, wherein the heater body 1 is provided with an electric heating module 3 and a servo fan 4 at the front and rear, the circuit module includes a main control chip 201, and the main control chip 201 is electrically connected to a first rotary encoder 202 and a second rotary encoder 203, the first rotary encoder 202 is electrically connected to an optocoupler circuit 204 and the electric heating module 3 in sequence, the second rotary encoder 203 is electrically connected to the servo fan 4, the humidifying module 5 is installed on the top of the heater body 1, and the output end of the humidifying module 5 is arranged in front of the electric heating module 3.

[0029] The circuit module includes a power conversion circuit 6, which includes an electrically connected rectifier bridge 601, a power management chip 602 and a voltage regulator chip 603, and the power conversion circuit 6 is electrically connected to the electric heating module 3, the servo fan 4 and the humidification module 5. The power conversion circuit 6 can convert the AC mains into DC power used by various electronic components and supply power uniformly, thereby improving the integration of the equipment.

[0030] A first MOS switch circuit 205 is electrically connected between the power conversion circuit 6 and the humidification module 5 , and a second MOS switch circuit 206 is electrically connected between the power conversion circuit 6 and the servo fan 4 .

[0031] The main control chip 201 is electrically connected to a temperature sensor 7, and the temperature sensor 7 is arranged in front of the electric heating module 3. The temperature sensor 7 arranged in front of the electric heating module 3 is more sensitive in detection.

[0032] The humidification module 5 includes a water tank 501 . A water level sensor 502 is disposed at the bottom of the water tank 501 . A humidity sensor 503 is disposed at the tail end of the humidification module 5 . The humidification module 5 is electrically connected to the main control chip 201 .

[0033] The first rotary encoder 202 is electrically connected to a temperature display screen 8 , and the second rotary encoder 203 is electrically connected to a wind speed display screen 9 . The first rotary encoder 202 , the second rotary encoder 203 , the temperature display screen 8 and the wind speed display screen 9 are installed on the same side of the heater body 1 .

[0034] The encoder knob and display screen set on the same side make it convenient for users to adjust and confirm the heating temperature and fan speed of the equipment as needed.

[0035] The electric heating module 3 includes an electric heating grid sheet. The surface area of ​​the grid-shaped electric heating sheet in contact with the air is much larger than the surface area of ​​a single tube or a flat plate structure, which can effectively improve the heating efficiency.

[0036] The main control chip 201 can be a single-chip microcomputer chip commonly used in the market, which is used to link various electronic components. The servo fan 4 can be a product on the market, and the wind speed can be adjusted according to the control of the single-chip microcomputer.

[0037] In actual use, when the first rotary encoder 202 and the second rotary encoder 203 are at zero position, the main control chip 201 links the first MOS switch circuit 205 and the second MOS switch circuit 206 to be disconnected, and the device is in a closed state.

[0038] When the knobs of the first rotary encoder 202 and the second rotary encoder 203 are rotated by the user to increase, the main control chip 201 adjusts the operating state of the electric heating module 3 through the optical coupling circuit 204 according to the numerical ratio of the first rotary encoder 202. When the temperature sensor 7 detects that the temperature reaches the set value, the operating power of the electric heating module 3 is reduced to keep the temperature stable. Optical coupling control heating is commonly used in the market and can achieve precise control of temperature.

[0039] At the same time, the second MOS switch circuit 206 is also turned on, and the main control chip 201 is linked to the servo fan 4 to adjust the running wind speed according to the numerical ratio of the second rotary encoder 203 .

[0040] On the other hand, since the humidity sensor 503 and the water level sensor 502 are provided, when the main control chip 201 detects that the humidity is low, the first MOS switch circuit 205 can be automatically turned on to start the humidification module 5, and the humidification is automatically stopped after the water stored in the water tank 501 is exhausted, so as to avoid damage to the equipment. The humidity sensor 503 is arranged on a side away from the output end to prevent the water sprayed from the output end of the humidification module 5 from interfering with the detection.

[0041] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
