[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0026] Reference Figures 1 to 5 , is an embodiment of the present utility model, which provides an air conditioner fan with a dustproof structure, including a housing 100, and a copper tube 101 arranged in the inner cavity of the housing 100, a protective ring 102a is provided on one side of the housing 100, and a fan 102 is provided on the housing 100 inside the protective ring 102a through a bracket. A first filter screen 102b is provided on one side of the housing 100, and a second filter screen 201 is provided on the other side. The second filter screen 201 cooperates with a filter sleeve 202. The filter sleeve 202 is arranged at the transmission end of the dustproof component 200. The filter sleeve 202 moves to make the second filter screen 201 fit with the filter sleeve 202, thereby changing the size of the filter holes. The dustproof component 200 is arranged on the housing 100;

[0027] The filter sleeve 202 is pressed against the cleaning end of the dust removal component 300 . The cleaning end is arranged in the inner cavity of the dust removal component 300 . The dust removal component 300 is arranged on the housing 100 .

[0028] Specifically, the copper tube inside the shell 100 is mainly used to transmit refrigerant. In the air-conditioning system, the refrigerant is transmitted from the indoor unit to the outdoor unit through the copper tube. In the outdoor unit, the refrigerant is compressed and condensed by the compressor and other components, and then the cooled refrigerant is sent back to the indoor unit to realize a cyclic refrigeration process. In order to accelerate heat conduction, a fan 102 and a protective ring 102a that supports the fan 102 are provided. The other end of the shell 100 also needs to be conductive over a large area so that heat can be quickly conducted out of the interior of the shell 100. The first filter 102b and the second filter 201 are respectively installed at the two conductive parts of the shell 100 to achieve a dust-proof effect. Another filter sleeve 202 is further provided on the filter. When the fan 102 is started, the filter sleeve 202 rotates one side to fit with the second filter screen 201, so that the filter holes of the filter screen reconstructed by the two are of the same size as the filter holes of the single second filter screen 201, which can smoothly discharge hot air. When the fan 102 is turned off, the filter screen reconstructed by the other side and the second filter screen 201 becomes very small, so that dust cannot pass through, thereby isolating dust. When the filter sleeve 202 rotates, the cleaning end of the dust removal component 300 is pressed into contact with the surface of the filter sleeve 202, scraping off the dust on the filter sleeve 202 and falling along the inner cavity of the dust removal component 300, thereby cleaning the dust on the filter screen surface.

[0029] Furthermore, the first filter screen 102b cooperates with the filter sleeve 202, and in view of the above, both ends of the housing 100 are better dust-proof and dust-isolating.

[0030] like Figures 1-6 As shown, illustratively, the filter sleeve 202 is formed by connecting a first filter sleeve net 202a and a second filter sleeve net 202b end to end. The first filter sleeve net 202a and the second filter sleeve net 202b have the same pore size. The first filter sleeve net 202a and the second filter screen 201 are attached to form a first overlapping filter screen 200-1. The second filter sleeve net 202b and the second filter screen 201 are attached to form a second overlapping filter screen 200b. The pore size of the first overlapping filter screen 200-1 is smaller than any individual pore size of the first filter sleeve net 202a and the second filter screen 201. The pore size of the second overlapping filter screen 200b is equal to any individual pore size of the second filter sleeve net 202b and the second filter screen 201.

[0031] Specifically, the apertures of the first filter sleeve 202a, the second filter sleeve 202b, and the second filter screen 201 are the same. The difference is that the first filter sleeve 202a and the second filter sleeve 202b are interwoven in different ways. Specifically, the first overlapping filter screen 200-1 formed by the combination of the first filter sleeve 202a and the second filter screen 201 has an aperture that is almost too small for dust to pass through. The second overlapping filter screen 200b formed by the combination of the second filter sleeve 202b and the second filter screen 201 has an aperture that is the same as the apertures of the first filter sleeve 202a, the second filter sleeve 202b, and the second filter screen 201. The filter sleeve 202 is set on the transmission end of the dustproof component 200. Specifically, , the filter sleeve 202 is sleeved on the driven shaft 204 and the output shaft 205, the two shafts are connected by a support frame 203 and are installed on the side of the shell 100, and a driving motor 206 is installed at one end of the output shaft 205. When the fan 102 is turned on, the driving motor 206 rotates a certain number of circles to allow the second filter sleeve net 202b of the filter sleeve 202 to overlap with the second filter screen 201. Similarly, when the fan 102 is turned off, the first filter sleeve net 202a of the filter sleeve 202 can overlap with the second filter screen 201. In this way, when the air conditioner outdoor unit is turned on, the shell 100 is connected and has a dust-proof effect. When the air conditioner outdoor unit is turned off, the shell 100 is connected and has a dust-isolating effect.

[0032] Specifically, the driving motor 206 can be realized by the following steps: 1. Connecting a delay relay or timer to the circuit of the air conditioning system to ensure that it can control the power switch of the motor; 2. Setting the delay time of the delay relay or timer to a predetermined value; 3. When the air conditioning is turned on, the delay relay or timer automatically starts and disconnects the circuit after the predetermined value, stopping the rotation of the motor; 4. When the air conditioning is turned off, the delay relay or timer is triggered again, causing the motor to rotate again for the predetermined value and then stop;

[0033] To more clearly describe the working principle of the drive motor 206, specifically: 1. Connect the power cord of the air conditioning system to the COM (common) port of the time delay relay; 2. Connect the NO (normally open) port of the time delay relay to the power cord of the motor; 3. Set the delay time of the time delay relay to a predetermined value; 4. When the air conditioner is turned on, the time delay relay triggers, energizing the motor, and the motor begins to rotate; after the predetermined value, the time delay relay disconnects the circuit, and the motor stops rotating; 5. When the air conditioner is turned off, the delay relay triggers again, energizing the motor, and the motor rotates again for the predetermined value before stopping;

[0034] The cleaning end of the dust removal component 300 is a brush 302, which is arranged in the inner cavity of the guide shell 301. The guide shell 301 is arranged on one side of the shell 100. The brush 302 cleans the dust on the surface of the filter and unclogs the filter holes.
