[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention sets a pretreatment, and drives the motor shaft to rotate through the servo motor 1, which in turn drives the propeller fan to rotate and generate suction, and then sucks the air to be dried into the pretreatment box for pretreatment. First, the handle is rotated to rotate the shaft 2 and make the porous absorbent cotton perpendicular to the air flow direction. The air with moisture will first contact the porous absorbent cotton 85. The porous absorbent cotton will absorb a small amount of moisture in the air, and the porous absorbent cotton will also adhere to dust and impurities in the air to prevent these impurities from entering the drying chamber and causing blockage.

[0021] 2. The present invention sets an auxiliary mechanism. When the driving mechanism is working, the staff needs to rotate the handle to rotate the porous absorbent cotton ninety degrees. Then the wind force generated by the propeller fan will blow the wind shield and drive the sliding magnetic plate to move toward the magnetic block. After moving a certain distance, the magnetic force generated by the magnetic block on the sliding magnetic plate will become larger, so that the sliding magnetic plate continues to move and drives the impact rod to collide with the baffle plate, so that the rotating shaft rotates. At the same time, the motor shaft drives the support column to rotate. The centrifugal force generated causes the telescopic spring to stretch and rotate the rotating plate ninety degrees, so that the rotating plate is always in contact with the porous absorbent cotton. The pressing block will squeeze the porous absorbent cotton, so that part of the water adsorbed on the washing cotton is squeezed out, thereby preventing the subsequent water absorption effect from deteriorating. At the same time, the scratch plate will also scrape the dust into the water flow groove.

[0022] 3. The present invention is provided with a drying mechanism. When the air that needs to be further dried and the low-temperature refrigerant enter the drying chamber, the refrigerant will enter the hollow tube. Then, the servo motor 2 drives the gear 1 to rotate, and then drives the gear 2 and the hollow tube to rotate. The centrifugal force generated by the rotation causes the gas-liquid mixed refrigerant to be ejected through the outlet of the air outlet plate. At the same time, the rotation of the air outlet plate drives the air circulation and fully mixes and contacts with the ejected refrigerant, so that the moisture in the air condenses into water droplets or ice cubes, thereby improving the drying efficiency.

[0023] 4. The present invention is provided with a spreading mechanism. When the refrigerant is sprayed out from the discharge port, the moisture in the air at the discharge port may be directly turned into an ice layer, thereby blocking the discharge port and causing the subsequent refrigerant to be unable to flow out from the discharge port. At regular intervals, the servo motor 2 will stop working, thereby stopping the rotation of the hollow tube, and the centrifugal force generated by the rotation will disappear, so that the elastic force of the telescopic spring 3 will drive the support plate 2 and the impact column to impact the discharge port, thereby breaking the generated ice layer and preventing the discharge port from being blocked.

[0040] Example 1, using Figure 1-Figure 14 A low-temperature dehumidification drying unit according to one embodiment of the present invention is described as follows.

[0041] like Figure 1-Figure 3 As shown, a low-temperature dehumidification drying unit of the present invention comprises a chassis 1, a base 2 is fixedly connected to the bottom of the chassis 1, a vent 3 is provided on the chassis 1, a temperature display 4 is fixedly connected to the outer surface of the chassis 1, an air outlet mechanism 5 is fixedly connected to the side of the chassis 1 close to the temperature display 4, a tool box 10 is fixedly connected to the top of the chassis 1, and a refrigeration mechanism 6 is fixedly connected to the inner wall of the chassis 1;

[0042] A driving mechanism 7, the driving mechanism 7 is used to inhale air that needs to be dried;

[0043] A pre-treatment mechanism 8, the pre-treatment mechanism 8 is used to deal with the situation where the air humidity is too high;

[0044] A drying mechanism 9, the drying mechanism 9 is used to dry the moisture in the air;

[0045] When a low-temperature dehumidification drying unit is working, the refrigerant is first placed in the refrigeration mechanism 6, which compresses the refrigerant into a low-temperature and low-pressure gas-liquid mixed refrigerant. Then the driving mechanism 7 inhales the air, and the pretreatment mechanism 8 absorbs part of the moisture. Finally, the air enters the drying mechanism 9 and turns the moisture in the air into water droplets and ice droplets.

[0046] like Figure 12-13 As shown, the drying mechanism 9 includes a drying chamber 91, the outer surface of the drying chamber 91 is fixedly connected to a servo motor 2 92, the output end of the servo motor 2 92 is fixedly connected to a gear 1 96, one end of the drying chamber 91 close to the servo motor 2 92 is fixedly connected to an interface 94, a side of the inner wall of the drying chamber 91 close to the interface 94 is rotatably connected to a gear 2 97, the bottom of the drying chamber 91 is fixedly connected to an air outlet pipe 95, and the inner wall of the gear 2 97 is fixedly connected to a material spreading mechanism 98;

[0047] like Fig.14As shown, the spreading mechanism 98 includes a hollow tube 981, and air outlet plates 982 are evenly arranged on the outer surface of the hollow tube 981, and an outlet port 983 is arranged at one end of the air outlet plate 982 away from the hollow tube 981, and side plates 984 are symmetrically arranged on both sides of the air outlet plate 982, and both ends of the air outlet plate 982 are fixedly connected to the outer surfaces of the side plates 984, and one end of the side plate 984 away from the air outlet plate 982 is fixedly connected to a telescopic spring three 985, and the telescopic spring three 985 is already in a compressed state when the hollow tube 981 does not rotate, and one end of the telescopic spring three 985 close to the outlet port 983 is fixedly connected to a support plate two 986, and one side of the support plate two 986 close to the outlet port 983 is evenly provided with impact columns 987, and the outer surface of the support plate two 986 is in contact with one end of the air outlet plate 982 away from the hollow tube 981.

[0048] When the air that needs to be further dried and the low-temperature refrigerant enter the drying chamber 91, the refrigerant will enter the hollow tube 981, and then the servo motor 2 92 drives the gear 1 96 to rotate, and then drives the gear 2 97 and the hollow tube 981 to rotate. The centrifugal force generated by the rotation causes the gas-liquid mixed refrigerant to be ejected through the outlet 983 of the air outlet plate 982. At the same time, the rotation of the air outlet plate 982 drives the air circulation and fully mixes with the ejected refrigerant, so that the moisture in the air condenses into water droplets or ice cubes, thereby improving the drying efficiency.

[0049] When the refrigerant is sprayed out from the discharge port 983, the moisture in the air at the discharge port 983 may be directly turned into an ice layer, thereby blocking the discharge port 983 and causing the subsequent refrigerant to be unable to flow out from the discharge port 983. At regular intervals, the servo motor 2 92 will stop working, thereby stopping the rotation of the hollow tube 981. The centrifugal force generated by the rotation will disappear, so that the elastic force of the telescopic spring 3 985 will drive the support plate 2 986 and the impact column 987 to impact the discharge port 983, thereby breaking the generated ice layer and preventing the discharge port 983 from being blocked.

[0050] like Figure 10-11 As shown, the refrigeration mechanism 6 includes a compressor 61, a feed pipe 62 is fixedly connected to the top of the compressor 61, a pipe 1 63 is fixedly connected to the output end of the compressor 61, a condenser 64 is fixedly connected to the end of the pipe 1 63 away from the compressor 61, a support frame 65 is fixedly connected to the outer surface of the condenser 64, an outer surface of the support frame 65 is fixedly connected to the inner wall of the chassis 1, a pipe 2 66 is fixedly connected to the top of the condenser 64, an end of the pipe 2 66 away from the condenser 64 is fixedly connected to an expansion valve 67, a support rod 1 69 is fixedly connected to the outer surface of the expansion valve 67, and a pipe 3 68 is fixedly connected to the end of the expansion valve 67 away from the pipe 2 66.

[0051] First, the compressor 61 is started to compress the refrigerant into a high-temperature and high-pressure gas state. Then, the high-temperature and high-pressure refrigerant gas enters the condenser 64, and the refrigerant gas is cooled and liquefied into a high-pressure liquid. Then, the high-pressure liquid refrigerant passes through the expansion valve 67 to form a low-temperature and low-pressure gas-liquid mixed refrigerant. Finally, the gas-liquid mixed refrigerant enters the hollow tube 981 through the pipeline three 68 and the interface 94.

[0052] The specific workflow is as follows:

[0053] During operation, air enters the drying chamber 91, and at the same time, the compressor 61 starts to compress the refrigerant into a high-temperature and high-pressure gas state. Then, the high-temperature and high-pressure refrigerant gas enters the condenser 64, and the refrigerant gas is cooled and liquefied into a high-pressure liquid. Then, the high-pressure liquid refrigerant passes through the expansion valve 67 to form a low-temperature and low-pressure gas-liquid mixed refrigerant. The refrigerant will enter the hollow tube 981, and then the servo motor 2 92 drives the gear 1 96 to rotate, and then drives the gear 2 97 and the hollow tube 981 to rotate. The centrifugal force generated by the rotation causes the gas-liquid mixed refrigerant to be ejected through the outlet 983 of the air outlet plate 982. At the same time, the rotation of the air outlet plate 982 drives the air circulation and fully mixes and contacts with the ejected refrigerant, thereby condensing the moisture in the air into water droplets or ice cubes.

[0058] The staff needs to rotate the handle 84 again to rotate the porous absorbent cotton 85 ninety degrees. Then the wind force generated by the propeller fan 77 will blow the wind shield 783 and drive the sliding magnetic plate 782 to move toward the magnetic block 787. After moving a certain distance, the magnetic force generated by the magnetic block 787 on the sliding magnetic plate 782 will become larger, so that the sliding magnetic plate 782 continues to move and drives the impact rod 784 to collide with the baffle plate 7862.

[0060] The rotating shaft 7861 rotates, and the motor rotating shaft 76 drives the supporting column 781 to rotate. The centrifugal force generated stretches the telescopic spring 7864 and rotates the rotating plate 7866 ninety degrees, so that the rotating plate 7866 is always in contact with the porous absorbent cotton 85. The pressing block 7868 squeezes the porous absorbent cotton 85, so that part of the water absorbed on the washing cotton is squeezed out, thereby preventing the subsequent water absorption effect from deteriorating. When resetting is required, the sliding magnetic plate 782 is moved to the initial position by pulling the pull rope 789.

[0061] The outer surface of the support ring 71 is fixedly connected to the end of the chassis 1 away from the refrigeration mechanism 6, one end of the support column 781 is fixedly connected to the end of the motor shaft 76 away from the servo motor 75, and both ends of the shaft 7861 are rotatably connected to the outer surface of the inner groove 785.

[0063] By rotating the handle 84 to rotate the rotating shaft 83 and make the porous absorbent cotton 85 perpendicular to the air circulation direction, the air containing moisture will first contact the porous absorbent cotton 85, and the porous absorbent cotton 85 will absorb a small amount of moisture in the air. The porous absorbent cotton 85 will also adhere to dust and impurities in the air to prevent these impurities from entering the drying chamber 91 and causing blockage.

First, the handle 84 is rotated to rotate the shaft 2 83 and make the porous absorbent cotton 85 perpendicular to the air flow direction. The air with moisture will first contact the porous absorbent cotton 85. The porous absorbent cotton 85 will absorb a small amount of moisture in the air, and the porous absorbent cotton 85 will also adhere to dust and impurities in the column air to prevent these impurities from entering the drying chamber 91 and causing blockage. After that, the staff needs to rotate the handle 84 again to rotate the porous absorbent cotton 85 ninety degrees, and then the propeller fan 77 generates The wind will blow the wind shield 783 and drive the sliding magnetic plate 782 to move toward the magnetic block 787. After moving a certain distance, the magnetic force generated by the magnetic block 787 on the sliding magnetic plate 782 will become larger, so that the sliding magnetic plate 782 continues to move and drives the impact rod 784 to collide with the baffle plate 7862, thereby causing the rotating shaft 7861 to rotate. At the same time, the motor shaft 76 drives the support column 1 781 to rotate. The centrifugal force generated causes the telescopic spring 1 7864 to stretch and rotate the rotating plate 7866 ninety degrees, so that the rotating plate 7866 is always in contact with the porous absorbent cotton 85, and the pressing block 7868 squeezes the porous absorbent cotton 85 to squeeze out some of the water adsorbed on the washing cotton.
