DETAILED DESCRIPTION

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0029] In order to remove the filter structure without unlocking the object, maintenance is more convenient, such as Figures 1 to 4 An air purification device for a growing greenhouse is shown, comprising: a purification box 1 for purifying the air of the growing greenhouse and a top cover 2 supported on the top of the purification box 1, the top cover 2 is symmetrically connected to holding rods 9 on both sides by screws, and the holding rods 9 are used to conveniently apply force to rotate the top cover 2 so as to screw out the top cover 2 and the threaded tube 4 together, and a limiting piece is welded on the end of the holding rod 9 away from the top cover 2 to prevent it from slipping out of the hand.

[0030] A filter plate 3 is nested and installed in the middle of the top cover 2 for preliminary filtering of the air. A threaded barrel 4 is integrally formed by injection molding at the bottom of the top cover 2. The integrally formed structure has high strength and is not easy to be damaged. The threaded barrel 4 is threadedly connected to the inner top of the purification box 1. A support net 5 is nested and installed at the inner bottom of the threaded barrel 4, and the top of the support net 5 is filled with a filter layer 6 (selected according to the specific type of filtered air, without limiting the specific type). A rubber plug 7 is inserted in the middle of the support net 5. The filter layer 6 can be replaced by opening the rubber plug 7. An exhaust fan 8 is installed on the lower part of the outer wall of one side of the purification box 1 through a mounting seat, and the input end of the exhaust fan 8 is connected to the inner side of the purification box 1. The purified air is extracted through the exhaust fan 9. A sign 17 is bonded to the outer wall of one side of the purification box 1, indicating the parameter information and precautions for use of the device. A bottom plate 18 is installed on the bottom of the purification box 1 through multiple bolts, and moving wheels 19 are installed at the four bottom corners of the bottom plate 18. The device can be moved by four moving wheels 19.

[0031] In order to fully purify the air, a water tank 10 is provided at the inner bottom of the purification box 1. The water tank 10 stores liquid medicine for purifying the air (also selected according to the specific type of air filtration). A filter screen 15 is nested and installed on the inner top of the water tank 10 to filter the liquid medicine. A connecting plate 16 is installed at the bottom of the water tank 10. The inner bottom of the purification box 1 is constructed with a connecting groove to facilitate the disassembly and assembly of the water tank 10, and the connecting plate 16 is threadedly connected to the inner side of the connecting groove.

[0032] A water pump 11 is installed on the lower part of the outer wall of one side of the water tank 10 through a mounting seat, and the input end of the water pump 11 is connected to the inner side of the water tank 10. The water pump 11 can transport the liquid medicine to the drain pipe 13 through the connecting pipe 12 and spray it out through the nozzle 14. The output end of the water pump 11 is connected to the connecting pipe 12, the top of the connecting pipe 12 is connected to the drain pipe 13, and a plurality of nozzles 14 are connected side by side at the bottom of the drain pipe 13. The plurality of nozzles 14 can evenly spray the liquid medicine to purify the air.

[0033] The exhaust fan 8 and the water pump 11 are both set as conventional instruments. The working principle, size and model are irrelevant to the function of this application, so they are not described in detail. They are both controlled by a remote control switch.

[0034] How it works

[0035] The air purification device for the planting greenhouse is connected to an external power supply. Under the continuous ventilation of the exhaust fan 8, the air is extracted from the exhaust fan 9 through the path of the filter plate 3, the filter layer 6, and the support net 5. The air can be filtered and purified once by the filter plate 3 and the filter layer 6. At the same time, the liquid medicine can be transported to the drain pipe 13 through the connecting pipe 12 by the water pump 11 and sprayed out through the nozzle 14. The filtered air will be purified twice by the liquid medicine sprayed by multiple nozzles 14. The above structure can fully purify the air.

[0036] When the filtering structure needs to be maintained, the user can directly hold the holding rod 8 with both hands to unscrew the top cover 2 and the threaded cylinder 4, and then the main structure for filtering connected to these structures can be maintained without inserting the body into the purification box 1, which makes maintenance more convenient.
