Specific embodiments
[0023] The following further describes the present utility model in detail with reference to the embodiments:
[0024] Embodiment 1
[0025] As Figures 1-6 shown, the present utility model provides a humidifying module of a fresh air blower, including an installation box 1. One side of the inner cavity of the installation box 1 is fixedly connected with a heating mechanism 2 for heating and evaporating water. The right side of the heating mechanism 2 and at the bottom of the inner cavity of the installation box 1 is fixedly connected with a temperature and humidity detection mechanism 3 for detecting the temperature and humidity of the air. The right side of the temperature and humidity detection mechanism 3 and on one side of the bottom of the inner cavity of the installation box 1 is fixedly connected with a humidifying mechanism 4. The installation box 1 includes a box body 11. The heating mechanism 2 includes a heater 22 for heating water. The temperature and humidity detection mechanism 3 includes a first humidity detector 34 for detecting the humidity of fresh air. The first humidity detector 34 is signal-connected to the heater 22.

The surface of the plug-in blocks 41 is inserted into the inner wall of the box body 11.
[0026] In this embodiment, by connecting the air inlet 15 to the air outlet pipe of the fresh air fan and the air outlet 16 to the air outlet pipe, fresh air can enter the box body 11 from the air inlet 15. When the first humidity detector 34 detects that the humidity of the fresh air is low, the water pump 45 is started through the controller 14, so that the water in the water storage bin 21 enters the water injection pipe 43 along the connecting pipe 44, and then enters the absorbent cotton 42 from a plurality of through holes. When the fresh air in the box body 11 passes through the absorbent cotton 42 and is discharged from the air outlet 16, the fresh air is humidified.
[0027] Embodiment 2
[0028] As Figures 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a first inspection door 12 is rotatably connected to the front surface of the box body 11, a second inspection door 13 is rotatably connected to the bottom of the box body 11, a cavity is provided at the lower end of the box body 11, a controller 14 is fixedly connected to the inner wall of the cavity at the lower end of the box body 11, an air inlet 15 for connecting an external air inlet pipe is provided on one side of the inner cavity of the box body 11, an air outlet 16 for connecting an external air outlet pipe and having a fresh air humidity sensor on its inner wall is provided on the other side of the inner cavity of the box body 11, a water storage bin 21 is fixedly connected to the upper surface of the heater 22, the bottom of the water storage bin 21 is fixedly connected to the bottom of the inner cavity of the box body 11, a liquid level sensor 23 for detecting the liquid level position is fixedly connected to the inside of the water storage bin 21, a light-transmitting observation window 24 is provided on the front surface of the water storage bin 21, a water adding pipe 25 is fixedly connected to the top of the inner cavity of the water storage bin 21, a water pump 26 is provided in the middle of the water adding pipe 25, an electromagnetic valve 27 is provided in the water adding pipe 25, a steam pipe 28 is fixedly connected to one side of the inner wall of the water storage bin 21, and a drain pipe 29 is provided at the lower end of the inner wall of the water storage bin 21.
[0029] In this embodiment, the humidity of the humidified fresh air is detected by the humidity sensor provided in the air outlet 16. According to the detection result, the subsequent water injection amount into the absorbent cotton 42 can be adjusted through the controller 14, so as to adjust the fresh air humidity. Moreover, the remaining amount of water in the water storage bin 21 can be detected by the liquid level sensor 23. When the remaining amount is small, the electromagnetic valve 27 is opened, and water is added into the water storage bin 21 through the water pump 26 along the water adding pipe 25.
[0030] Embodiment 3
[0031] As Figures 1-6As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a detection box 31 is fixedly connected to the bottom of the inner cavity of the box body 11. A temperature detector 32 is fixedly connected to the top of the inner wall of the detection box 31. A second humidity detector 33 is fixedly connected to one side of the inner wall of the detection box 31. The inner cavity of the detection box 31 is communicated with the water storage bin 21 through a steam pipe 28. A water injection pipe 43 is fixedly connected to the inner wall of the insertion block 41. One end of the water injection pipe 43 is fixedly connected to a communication pipe 44. A water pump 45 is arranged in the middle of the communication pipe 44. One end of the communication pipe 44 is communicated with the inside of the water storage bin 21. Through holes are formed in the surface of the water injection pipe 43.
[0032] In this embodiment, when the temperature detector 32 detects that the temperature of the fresh air is relatively low, the heater 22 is started. Under the action of the heater 22, the water in the water storage bin 21 is heated, so that the water injected into the absorbent cotton 42 is warm water, avoiding the water in the absorbent cotton 42 from freezing. At the same time, the heated water continuously generates high-temperature steam. While the steam can be used to assist in humidifying the air, the heat in the steam can heat the absorbent cotton 42, avoiding the fresh air from taking away too much heat from the water in the absorbent cotton 42 and causing it to freeze, making it more convenient to use. The settings of the first inspection door 12 and the second inspection door 13 facilitate the inspection of the humidification module, making it more convenient to use.

[0034] As Figures 1-6As shown, during use, the air inlet 15 is connected to the air outlet pipe of the fresh air machine, and the air outlet 16 is connected to the air outlet pipe, so that fresh air can enter the box body 11 from the air inlet 15. When the first humidity detector 34 detects that the humidity of the fresh air is low, the water pump 45 is started through the controller 14, so that the water in the water storage bin 21 enters the water injection pipe 43 along the communication pipe 44, and then enters the absorbent cotton 42 from multiple through holes. When the fresh air in the box body 11 passes through the absorbent cotton 42 and is discharged from the air outlet 16, the fresh air is humidified, and the humidity of the humidified fresh air is detected by the humidity sensor arranged in the air outlet 16. According to the detection result, the subsequent water injection volume into the absorbent cotton 42 can be adjusted through the controller 14, so as to adjust the humidity of the fresh air. And the water level sensor 23 can be used to detect the remaining water volume in the water storage bin 21. When the remaining amount is small, the solenoid valve 27 is opened, and water is added into the water storage bin 21 through the water pump 26 along the water supply pipe 25. When the temperature detector 32 detects that the temperature of the fresh air is low, the heater 22 is started. Under the action of the heater 22, the water in the water storage bin 21 is heated, so that the water injected into the absorbent cotton 42 is warm water, avoiding the water in the absorbent cotton 42 from freezing. At the same time, the heated water continuously generates high-temperature steam. While the steam can be used to assist in humidifying the air, the heat in the steam can heat the absorbent cotton 42, avoiding the fresh air from taking away too much heat in the water in the absorbent cotton 42 and causing it to freeze, making it more convenient to use. The setting of the first inspection door 12 and the second inspection door 13 can facilitate the inspection of the humidification module and make it more convenient to use.
[0035] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
