DETAILED DESCRIPTION

[0026] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The application will be described in further detail.

[0027] Please refer to Figures 1-3 The air conditioning equipment room ventilation structure is convenient to clean and maintain, comprising a first warm air pipe 1 and a second warm air pipe 6 connected through a connection structure at the head and tail ends. The first warm air pipe 1 and the second warm air pipe 6 connected together are used to ventilate and dissipate heat for the air conditioning equipment room.

[0028] A filter device is installed in the inner cavity of the end of the first warm air pipe 1 connected with the second warm air pipe 6. The filter device is used to filter dust in the air, so as to avoid dust entering the air conditioning equipment room along the first warm air pipe 1 and the second warm air pipe 6.

[0029] The first warm air pipe 1 further has a dust removal device embedded in the inner cavity, which is used to remove dust adhered to the inner wall of the first warm air pipe 1.

[0030] The connection structure comprises a plurality of metal elastic sheets 2 fixedly connected to the end of the first warm air pipe 1 and arranged in a ring shape. The first push plate 3 is fixedly connected to the inner side wall of the metal elastic sheet 2. A screw ring 4 is sleeved on the outer surface of the metal elastic sheet 2 and is screwed with the outer wall of the metal elastic sheet 2. The user can screw the screw ring 4 to the free end of the metal elastic sheet 2, and the plurality of metal elastic sheets 2 are gathered by the limiting action of the screw ring 4.

[0031] The connection structure further comprises a plurality of second push plates 7 fixedly connected to the end of the second warm air pipe 6 and corresponding to the first push plate 3. The second push plate 7 and the first push plate 3 are both provided with an inclined surface 8 matched with each other. During the gathering of the plurality of metal elastic sheets 2, the second push plate 7 is pushed to move towards the end of the first warm air pipe 1 under the action of the inclined surface 8, so as to connect the first warm air pipe 1 and the second warm air pipe 6 together.

[0032] Reference Figure 1 and Figure 3The outer side wall of the metal elastic sheet 2 is in an arc structure, and external threads are formed on the outer side wall of the metal elastic sheet 2. The screw ring 4 is screwed with the metal elastic sheet 2 through the external threads. The outer side wall of the metal elastic sheet 2 is arranged in an arc structure, so that the screw ring 4 is screwed with the plurality of metal elastic sheets 2 through the external threads. Therefore, when the user screws the screw ring 4 to the free end of the metal elastic sheet 2, the free ends of the plurality of metal elastic sheets 2 can be gathered.

[0033] With reference to Figure 2 The screw ring 4 is in an annular structure, and anti-skid grooves 5 for increasing friction are formed on the circumferential side of the screw ring 4. The anti-skid grooves 5 are formed on the outer surface of the screw ring 4, so as to increase the friction between the outer surface of the screw ring 4 and the palm of the user, and avoid the palm of the user from slipping with the screw ring 4 when the user screws the screw ring 4.

[0034] With reference to Figure 2 The connecting ends of the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6 are fixedly connected with sealing pads 9 which are the same in size and shape. The sealing pads 9 are annular, and the two sealing pads 9 are tightly attached to each other after the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6 are connected through the connecting structure. The sealing pads 9 are arranged at the connecting ends of the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6, so that the two sealing pads 9 are tightly attached to each other after the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6 are connected, thereby greatly improving the air tightness of the connecting part of the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6.

[0035] With reference to Figure 1 The filtering device comprises a filter element 10 which is embedded in the inner cavity of the first heating and ventilation pipe 1. A plurality of ear plates are fixedly connected to the circumferential side of the filter element 10, and bolts 11 which are screwed with the inner wall of the first heating and ventilation pipe 1 are arranged on the ear plates. The filter element 10 is arranged to filter the air entering the air conditioning equipment room, and the connection mode of screwing with the bolts 11 is not only stable, but also facilitates the user to install and dismount the filter element 10.

[0036] With reference to Figure 1 The dust removing device comprises two mounting plates 12 which are fixedly connected in the inner cavity of the first heating and ventilation pipe 1. A rotating shaft 13 which is rotatably connected with the mounting plate 12 is arranged in the middle section of the two mounting plates 12. Elastic extension rods 15 are fixedly connected with scraper plates 16 which are in sliding contact with the inner wall of the first heating and ventilation pipe 1 on both sides of the rotating shaft 13. When the rotating shaft 13 rotates, the scraper plates 16 can be driven to rotate through the elastic extension rods 15, so as to scrape off the dust attached to the inner side wall of the first heating and ventilation pipe 1. Since the elastic extension rods 15 have elasticity, when the scraper plates 16 are abraded due to long-term friction, the elastic extension rods 15 can be elongated to push the scraper plates 16 to always adhere to the inner wall of the first heating and ventilation pipe 1.

[0037] With reference to Figure 3The connecting part of the rotating shaft 13 and the mounting plate 12 is provided with a bearing, and one end of the rotating shaft 13 is fixedly connected with a fan blade 14. The bearing is arranged to reduce the resistance of the rotating shaft 13, and the fan blade 14 is arranged to push the fan blade 14 to rotate when air flows in the inner cavity of the first heating and ventilation pipe 1, thereby driving the scraper 16 mounted on the rotating shaft 13 to rotate and perform dust removal work.

[0038] The implementation principle of the present application is that when the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6 need to be connected, first, the end of the second heating and ventilation pipe 6 fixedly connected with the second push plate 7 is inserted into the gap between the plurality of metal springs 2, so that the first push plate 3 moves to the side of the second push plate 7 provided with the inclined surface 8. At this time, the user screws the screw ring 4 in the direction of the free end of the metal spring 2, so that the screw ring 4 drives the free end of the plurality of metal springs 2 to gather towards the center of the screw ring 4, and drives the plurality of first push plates 3 to move synchronously towards the center of the screw ring 4. The first push plate 3 can push the second push plate 7 through the inclined surface 8 during the movement, until the sealing gasket 9 provided at the end of the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6 tightly abut, realizing the connection of the first heating and ventilation pipe 1 and the second heating and ventilation pipe 6. When the user needs to disassemble the first heating and ventilation pipe 1, the screw ring 4 can be screwed in the direction of the first heating and ventilation pipe 1. At this time, the free end of the metal spring 2 loses the binding effect of the screw ring 4 and can be opened by an external force, so that the user can directly pull the second heating and ventilation pipe 6 outward to disassemble the second heating and ventilation pipe 6. The problem of the existing heating and ventilation pipe generally connected by an external connecting mechanism is avoided, and the user needs to carry and use more tools to disassemble when cleaning dust after a long time of use, which affects the cleaning efficiency.
