[0002] The main function of an air source heat pump is to absorb low-grade heat energy from the air and convert it into high-grade heat energy for heating, cooling, and hot water supply. Air source heat pumps can provide large volume, high pressure, and constant temperature hot water 24 hours a day to meet the different hot water needs of families. In the industrial field, air source technology is used for waste heat recovery, process heating, etc., to improve energy utilization efficiency.

[0003] When using existing air source heat pumps, their function is to convert low-grade heat energy in the air into high-grade heat energy for heating. Existing air source heat pumps use dust filters to prevent dust from entering the exhaust vent. However, existing dust filters have a screw hole on their surface, and screws are used to connect and fix the dust filter to the exhaust vent, which makes installation inconvenient and disassembly difficult. Utility Model Content

[0004] The purpose of this utility model is to provide an air source heat pump with a dustproof mesh that is easy to install and remove, in order to solve the problem mentioned in the background art that the existing dustproof mesh has a screw hole on its surface, and then screws are installed to connect and fix the dustproof mesh and the exhaust port, which leads to inconvenient installation and difficulty in disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air source heat pump with a dustproof mesh that is easy to install and remove, comprising:

[0006] The device body includes a device body, and exhaust vents are provided on both sides of the top of the device body. A dustproof net is provided on the top surface of the exhaust vents.

[0007] The exhaust vent is internally fitted with an assembly structure on both sides. The assembly structure includes a slide plate. One end of the slide plate is connected to a hinge frame. L-shaped positioning frames are sleeved on both sides of the hinge frame. A fixing screw is inserted inside the top of the L-shaped positioning frame. A nut is connected to the top of the fixing screw.

[0008] Preferably, the exhaust vent has movable slots on both sides, one end of the slide plate is inserted into the movable slot of the exhaust vent, and the slide plate and the L-shaped positioning frame are hinged together by a hinge frame.

[0009] Preferably, a through groove is provided on one side of the inner wall of the movable slot of the exhaust port, and the bottom end of the fixing screw passes through the through groove of the exhaust port and is connected to the top surface of the slide plate.

[0010] Preferably, the top surface of the L-shaped positioning frame has a through groove II, and the top surface of the dustproof net has positioning holes on both sides. The top of the fixing screw passes through the positioning hole in the dustproof net and is inserted into the through groove II of the L-shaped positioning frame. The fixing screw and the nut are connected by a thread for rotation.

[0011] Preferably, the surface of the dustproof net is provided with a locking mechanism, the locking mechanism including a first bearing, one end of the first bearing is connected to an adjusting screw, one end of the adjusting screw is rotatably connected to a support frame, the inner surface of the support frame is provided with a second bearing, the inner surface of the second bearing is connected to a limit rod, and the two sides of the support frame are abutted by fixing plates.

[0012] Preferably, the fixing plate is connected to one side of the exhaust port surface, the exhaust port surface is provided with a limiting groove, and one end of the limiting rod is connected to the inside of the limiting groove provided in the exhaust port.

[0013] Preferably, the support frame and the limiting rod are movably connected by a second bearing, the support frame has a threaded hole on its surface, the adjusting screw is rotatably connected inside the threaded hole of the support frame, and the dustproof net and the adjusting screw are movably connected by a first bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By inserting the sliding plate into the movable slot of the exhaust vent, and simultaneously inserting the fixing screw into the through slot one of the exhaust vent, the dustproof net and the L-shaped positioning frame are positioned. Then, the dustproof net is inserted into the exhaust vent, and the fixing screw is inserted into the positioning hole of the dustproof net. Then, the angle of the L-shaped positioning frame is rotated so that it rotates around the hinge frame as the axis, so that the L-shaped positioning frame is fitted onto the outer wall of one side of the exhaust vent. The top of the fixing screw is inserted into the through slot two of the L-shaped positioning frame. Then, the nut is rotated and connected to the outer surface of the top of the fixing screw to limit the angle of the L-shaped positioning frame. This achieves the limiting function between the exhaust vent and the dustproof net, avoiding the problems of inconvenient installation and difficult disassembly caused by using screws for connection and fixation.

[0016] 2. After the exhaust vent and dust screen are installed, the support frame is inserted between the fixed plates. The fixed plates are used to position the two sides of the support frame. Then, the angle of the adjusting screw is rotated so that the first bearing ensures that the rotation of the adjusting screw does not affect the angle of the dust screen. This allows the support frame to slide between the fixed plates, so that one end of the limiting rod is inserted into the limiting groove opened in the exhaust vent, thereby restricting the position of the dust screen and preventing it from moving upward, thus achieving the limiting effect of the dust screen.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An air source heat pump with a dustproof mesh that is easy to install and remove includes:

[0026] The device body 1 includes a device body 11. The device body 11 has exhaust vents 12 on both sides of its top end. The top surface of the exhaust vents 12 is provided with a dustproof net 13. The internal material of the dustproof net 13 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further details are made.

[0027] An assembly structure 2 is inserted inside both sides of the exhaust vent 12. The assembly structure 2 includes a slide plate 21. One end of the slide plate 21 is connected to a hinge frame 22. L-shaped positioning frames 23 are sleeved on both sides of the hinge frame 22. A fixing screw 24 is inserted inside the top of the L-shaped positioning frame 23. A nut 25 is connected to the top of the fixing screw 24.

[0028] Furthermore, movable slots are provided on both sides of the exhaust vent 12. One end of the slide plate 21 is inserted into the movable slot provided in the exhaust vent 12. The slide plate 21 and the L-shaped positioning frame 23 are hinged together by the hinge frame 22, so that the L-shaped positioning frame 23 is limited by the hinge frame 22 and the L-shaped positioning frame 23 can be adjusted in angle with the hinge frame 22 as the axis.

[0029] Furthermore, a through groove is provided on one side of the inner wall of the movable slot of the exhaust port 12. The bottom end of the fixing screw 24 passes through the through groove of the exhaust port 12 and is connected to the top surface of the slide plate 21. This allows the fixing screw 24 to position the exhaust port 12 and the dustproof net 13, thus preventing the dustproof net 13 from shifting.

[0030] Furthermore, the top surface of the L-shaped positioning frame 23 is provided with a through groove 2, and the top surface of the dustproof net 13 is provided with positioning holes on both sides. The top of the fixing screw 24 passes through the positioning hole of the dustproof net 13 and is inserted into the through groove 2 of the L-shaped positioning frame 23. The fixing screw 24 and the nut 25 are connected by a thread, so as to fix the fixing screw 24 and the nut 25 by the thread, thereby limiting the angle of the L-shaped positioning frame 23.

[0031] Furthermore, a locking mechanism 3 is provided on the surface of the dustproof net 13. The locking mechanism 3 includes a first bearing 31, one end of which is connected to an adjusting screw 32. A support frame 33 is rotatably connected to the outer surface of one end of the adjusting screw 32. A second bearing 34 is provided on the inner surface of the support frame 33. A limit rod 35 is connected to the inner surface of the second bearing 34. Fixed plates 36 abut against both sides of the support frame 33. This achieves the effect of limiting the position of the dustproof net 13, preventing it from moving upward, thereby limiting the position of the dustproof net 13.

[0032] Furthermore, the fixing plate 36 is connected to one side of the surface of the exhaust port 12. A limiting groove is opened on the surface of the exhaust port 12. One end of the limiting rod 35 is connected to the inside of the limiting groove opened in the exhaust port 12, so that one end of the limiting rod 35 is positioned by the limiting groove opened in the exhaust port 12, thereby limiting the dustproof net 13 by the limiting rod 35.

[0033] Furthermore, the support frame 33 and the limiting rod 35 are movably connected by the second bearing 34. The support frame 33 has a threaded hole on its surface. The adjusting screw 32 is rotatably connected to the threaded hole in the support frame 33. The dustproof net 13 and the adjusting screw 32 are movably connected by the first bearing 31, so that the angle of the dustproof net 13 is not affected when the limiting rod 35 is rotated by the first bearing 31.

[0034] Working principle: When assembling an air source heat pump with a dustproof mesh that is easy to disassemble and assemble, the sliding plate 21 is inserted into the movable slot of the exhaust port 12, and the fixing screw 24 is simultaneously inserted into the through slot one of the exhaust port 12 to position the dustproof mesh 13 and the L-shaped positioning frame 23. Then, the dustproof mesh 13 is inserted into the exhaust port 12, and the fixing screw 24 is inserted into the positioning hole of the dustproof mesh 13. Then, the angle of the L-shaped positioning frame 23 is rotated so that it rotates around the hinge frame 22 as the axis, so that the L-shaped positioning frame 23 is sleeved on one side of the outer wall of the exhaust port 12, and the top of the fixing screw 24 is inserted into the through slot two of the L-shaped positioning frame 23. Then, the nut 25 is rotated and connected to the outer surface of the top of the fixing screw 24 to limit the angle of the L-shaped positioning frame 23, thereby achieving the limiting effect between the exhaust port 12 and the dustproof mesh 13.

[0035] When locking the air source heat pump with a dustproof net that is easy to install and remove, after installing the exhaust port 12 and the dustproof net 13, the support frame 33 is inserted between the fixing plates 36. The fixing plates 36 are used to position the two sides of the support frame 33. Then, the angle of the adjusting screw 32 is rotated so that the first bearing 31 ensures that the rotation of the adjusting screw 32 does not affect the angle of the dustproof net 13. This allows the support frame 33 to slide between the fixing plates 36, so that one end of the limiting rod 35 is inserted into the limiting groove opened in the exhaust port 12, thereby restricting the position of the dustproof net 13 and preventing the dustproof net 13 from moving upward, thus achieving the limiting effect of the dustproof net 13.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
