[0002] Heat pump is a highly efficient energy-saving device that fully utilizes low-grade thermal energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but not spontaneously in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize the low-grade thermal energy that is difficult to use to achieve energy saving.

In the above application document, the motor drives the plurality of fan blades to accelerate the entry of external air into the heat pump drying unit, and drives the cleaning brush to rotate and clean the surface of the filter, so that the surface of the filter is kept clean at all times. The motor drives the plurality of fan blades and also needs to drive the cleaning brush to keep rotating, which may bring a burden to the motor, resulting in poor efficiency of driving the fan blades to accelerate the entry of external air.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a heat pump unit shell structure comprises: a heat pump unit shell 1, a protective mesh plate 2 is arranged on the side of the heat pump unit shell 1, a mounting plate 4 is fixedly connected inside the heat pump unit shell 1, a motor 5 is fixedly installed on the side of the mounting plate 4, the motor 5 is fixedly connected to a rotating shaft 6 through its output shaft, and a fan 7 is fixedly connected to the rotating shaft 6 at one end away from the motor 5, the heat pump unit shell 1 is provided with a dust cleaning mechanism 8 and an impact mechanism 9, the dust cleaning mechanism 8 comprises a hydraulic bin 81 and a rotating gear 88, the hydraulic bin 81 passes through and is fixedly connected to the side of the heat pump unit shell 1, a push rod 82 is slidably connected to the inner wall piston at one end of the hydraulic bin 81, a cleaning brush 83 is fixedly connected to the bottom of the push rod 82, a pressure rod 84 is slidably connected to the inner wall piston at the other end of the hydraulic bin 81, a pressure plate 85 is fixedly connected to the bottom of the pressure plate 85, a gear rod 86 is fixedly connected to the bottom of the pressure plate 85, a return spring 87 is sleeved on the surface of the pressure rod 84, and the rotating gear 88 is fixedly connected to the middle end of the rotating shaft 6.

[0026] As an optional implementation, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the bristles of the cleaning brush 83 are made of nylon, and the bristles of the cleaning brush 83 are in contact with the surface of the protective mesh plate 2 .

[0027] In this way, the bristles made of nylon material are not easy to fall off and be damaged, and are not easy to generate static electricity. When the cleaning brush 83 moves up and down repeatedly, its bristles will clean the surface of the protective mesh plate 2.

[0028] As an optional implementation, Figure 4 As shown, the rotating gear 88 is an incomplete gear, and the teeth on the rotating gear 88 are matched with the teeth on the gear rod 86.

[0029] Thus, when the rotating gear 88 rotates and the teeth on the rotating gear 88 mesh with the teeth on the gear rod 86 , the gear rod 86 is driven to move upward.

[0030] As an optional implementation, Figure 4 As shown, both ends of the return spring 87 initially contact the top of the pressure plate 85 and one end of the hydraulic chamber 81 close to the pressure rod 84 .

[0031] In this way, when the pressing plate 85 moves upward, it will press the return spring 87, so that the return spring 87 is gradually tightened.

[0032] As an optional implementation, Figure 1 , Figure 2 , Figure 5As shown, the impact mechanism 9 includes a bracket 91, one end of the bracket 91 is fixedly connected to the side of the heat pump unit housing 1, the other end of the bracket 91 is fixedly connected to a pressure chamber 92, one end of the pressure chamber 92 is provided with an air bag 93, the other end of the pressure chamber 92 is slidably connected to the inner wall piston of the other end of the pressure chamber 92 is connected to a striker rod 94, and the end of the striker rod 94 away from the pressure chamber 92 is fixedly connected to a striker block 95.

[0033] As an optional implementation, Figure 3 , Figure 5 As shown, the airbag 93 is located directly below the cleaning brush 83, and the airbag 93 is in an expanded state in an initial state.

[0034] In this way, when the cleaning brush 83 moves downward, it will squeeze the air bag 93, and the air pressure inside the air bag 93 will enter the air pressure chamber 92 to push the striker 94 to move rightward.

[0035] As an optional implementation, Figure 1 , Figure 2 , Figure 5 As shown, the impact block 95 is made of rubber, and in the initial state, the impact block 95 is close to the surface of the protective mesh plate 2.

[0036] In this way, the impact block 95 has a certain elasticity and will not cause damage to the protective mesh plate 2. The impact block 95 moves to the right and hits the surface of the protective mesh plate 2 to cause it to vibrate slightly.

[0037] In this embodiment, the motor 5 is turned on, and the motor 5 drives the rotating shaft 6 to rotate through its output shaft. The rotation of the rotating shaft 6 drives the fan 7 to rotate. The rotation of the fan 7 accelerates the external air to enter the heat pump unit casing 1. The rotation of the rotating shaft 6 also drives the rotating gear 88 to rotate. At the beginning, when the rotating gear 88 rotates and the teeth on the gear rod 86 are meshed, it will drive the gear rod 86 to move upward. The upward movement of the gear rod 86 will drive the pressure plate 85 and the pressure rod 84 to move upward. At this time, the return spring 87 is squeezed and gradually tightened. When the pressure rod 84 moves upward, the hydraulic pressure in the hydraulic chamber 81 drives the push rod 82 to move downward. The downward movement of the push rod 82 drives the cleaning brush 83 to move downward. When the rotating gear 88 rotates to the point where the toothless part is out of mesh with the gear rod 86, the return spring 87 will rebound and drive the pressure plate 85 and the pressure rod 84 to move downward and restore. At this time, the hydraulic pressure in the hydraulic chamber 81 will drive The push rod 82 moves upward to restore, and the cleaning brush 83 moves upward to restore, thus forming a cycle. The cleaning brush 83 repeatedly moves up and down and its bristles will clean the surface of the protective mesh plate 2 to prevent dust and hair from clogging it. At the same time, it is not easy to cause a burden on the motor 5, affecting the rotation of the fan 7 and accelerating the efficiency of the external air intake. When the cleaning brush 83 moves downward, it will squeeze the air bag 93. The air pressure inside the air bag 93 will enter the air pressure chamber 92 to push the impact rod 94 to move right. The impact rod 94 moves right and drives the impact block 95 to move right and hit the surface of the protective mesh plate 2. When the cleaning brush 83 moves upward to leave the air bag 93, the rebound air pressure of the air bag 93 returns to the air bag 93. At this time, the impact rod 94 drives the impact block 95 to move left and leave the surface of the protective mesh plate 2. The impact block 95 repeatedly hits the surface of the protective mesh plate 2, causing the protective mesh plate 2 to vibrate, shaking off the dust on it, thereby enhancing the cleaning effect of the protective mesh plate 2.
