[0030] Specifically, as Figure 3 The connecting mechanism 6 includes plug block 601, plug hole 602 and limit pin 603, the side close to fixed plate 202 of plug block 601 is fixedly connected with fixed plate 202, plug hole 602 is formed in the inside of sliding frame 204, plug block 601 is movably inserted in the inside of sliding frame 204, the side close to sliding frame 204 of limit pin 603 passes through sliding frame 204 and extends to the inside of plug block 601, and the surface of limit pin 603 is threadedly connected with the inside of sliding frame 204.

[0031] In the embodiment: by moving sliding frame 204 up and down on the surface of air source heat pump unit body 1 manually, the sliding frame moves up and down, the bristles 203 can be moved up and down, so that the dust on the inner wall of the mesh body 10 is brushed off, and the fan 201 is controlled to work, so that the dust after brushing can be sucked into the fan 201 and discharged to the surrounding, avoiding the dust from entering the air source heat pump unit body 1 and affecting the normal work of the air source heat pump unit body 1, and by rotating the limit pin 603 to disassemble, the plug block 601 can be separated from the plug hole 602, the fixed plate 202 can be separated from the sliding frame 204, the fan 201 can be cleaned and stored conveniently, and the problem that the inner wall of the mesh of the shell of the existing air source heat pump unit is attached with dust after being exposed to the outside for a long time, affecting the smoothness of the mesh, the staff needs to wave the brushing tool to brush off, the dust falling off is easy to drop or drift into the air source heat pump unit by gravity, affecting the normal work of the air source heat pump unit.

[0035] In this embodiment: the nylon bristles 203 can effectively peel off the dust attached to the inner wall of the mesh body 10 due to its good wear resistance and flexibility, without damaging the mesh body 10. The supporting of the bottom fixed plate 202 by the supporting block 4 can avoid excessive downward movement of the sliding frame 204 and the fixed plate 202. The upward and downward movement of the sliding frame 204, the bristles 203, the fixed plate 202 and the fan 201 can be facilitated by holding the pull rod 3.

[0041] Working principle: when the air source heat pump unit body 1 works normally, the components in the air source heat pump unit body 1 such as compressor, evaporator, condenser and the like work cooperatively, and heat is transported through heat pump circulation to meet the heating or refrigeration demand. The air source heat pump unit body 1 is a mature technology disclosed in the prior art, and will not be described herein. When the air source heat pump unit body 1 works, air continuously enters and exits the unit through the plurality of mesh bodies 10 on the shell. When passing through the mesh bodies 10, part of the dust adheres to the inner wall of the mesh bodies 10 due to inertial impact, electrostatic adsorption and the like. If not cleaned in time, it will seriously affect the ventilation and heat dissipation of the air source heat pump unit body 1 and the normal operation. When the mesh bodies 10 need to be cleaned, only the fan 201 needs to be controlled to work, and then two workers wear protective masks and move the pull rod 3 up and down from both sides of the air source heat pump unit body 1, so that the sliding frame 204 moves up and down on the surface of the air source heat pump unit body 1. At this time, the bristles 203 fixed on the sliding frame 204 will scrape and clean the dust on the inner wall of the mesh bodies 10. The nylon bristles 203 can effectively strip the dust adhering to the inner wall of the mesh bodies 10 due to their good wear resistance and flexibility, without damaging the mesh bodies 10. During repeated cleaning, even if some stubborn dust clumps are encountered, the nylon bristles 203 can rely on their own elastic deformation to penetrate into the gap between the dust and the wall of the mesh bodies 10, loosen and remove the dust. At this time, the suction force generated by the working fan 201 can suck the dust removed by the bristles 203 into the inlet and discharge it to the surrounding direction, which can avoid the dust removed by the bristles 203 from entering the air source heat pump unit body 1 and affecting the normal work of the air source heat pump unit body 1. When the fan 201 needs to be disassembled and stored or disassembled and cleaned, the limiting pin 603 is disassembled, and then the plug block 601 can be pulled out of the plug hole 602 by the hand-held pull ring 5, so that the fixed plate 202 and the fan 201 can be conveniently disassembled. When the bristles 203 need to be cleaned, the screws 9 are disassembled, the stop block 7 is separated from the air source heat pump unit body 1, and then the sliding frame 204 is moved upward to be separated from the air source heat pump unit body 1, so that the bristles 203 can be conveniently cleaned. This avoids the problem that the inner wall of the mesh of the existing air source heat pump unit shell is attached with dust after being exposed to the outside for a long time, which affects the smoothness of the mesh, and the workers need to wave the cleaning tool to remove the dust, which is easy to fall or drift into the air source heat pump unit by gravity, affecting the normal work of the air source heat pump unit.

[0042] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
