[0025] In an exemplary embodiment of the present disclosure, an air supply duct of an air conditioner having a dust-proof net and dust removal device is provided, such as Figure 1 As shown, Figure 1 is a schematic diagram showing an air supply duct structure of an air conditioner with a dust-proof net dust removal device according to an exemplary embodiment; Figure 2 is a schematic diagram showing the position of a plug according to an exemplary embodiment; Figure 3 is a schematic diagram showing the position of a head according to an exemplary embodiment; Figure 4 According to an exemplary embodiment, Figure 3 The diagram in the figure shows the structure of the dust removal component. Figures 1 to 4 Provide explanation.

[0026] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0027] Reference Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides an air supply duct for an air conditioner with a dust-proof net and dust removal device. The air supply duct for an air conditioner with a dust-proof net and dust removal device comprises:

[0028] The air duct 1 is internally fixed with a filter 4 tilted toward the air inlet direction;

[0029] The dust removal assembly 2 includes a hard suction pipe 21 which is slidably connected to the air duct 1 along the inclination direction of the filter 4, a dust box 22 which is fixed to and connected to the hard suction pipe 21, and a dust removal brush 23 which is fixed to the dust box 22. The hard suction pipe 21 extends out of the air duct 1, and the opening of the dust box 22 is arranged toward the filter 4. The dust removal brush 23 extends from one side of the filter 4 to the other side of the filter 4 and divides the opening of the dust box 22 into two parts, an upper part and an lower part.

[0030] For example, refer to Figure 1 and Figure 3 The air duct 1 is a square tube structure, the air flow moves from one end of the air duct 1 to the other end of the air duct 1, the filter 4 is rectangular and fixed inside the air duct in an inclined posture, and the filter 4 is inclined toward the gas inflow direction, that is, the air flow in the air duct 1 has a downward flow trend after contacting the filter 4, and the dust carried in the air flow also moves downward under the filtering and guiding action of the filter 4. More filtered dust accumulates at the lower end of the filter 4, which reduces the activity range of dust in the air duct 1 and reduces the possibility of dust passing through the filter 4 during continuous movement.

[0031] Reference Figure 1 and Figure 2 The hard air suction pipe 21 is, for example, a hollow pipe made of hard plastic (or steel). The hard air suction pipe 21 is parallel to the filter screen 4, and the hard air suction pipe 21 extends along the inclination direction of the filter screen 4. The bottom end of the hard air suction pipe 21 penetrates the top outside of the air duct 1 and extends into the air duct 1. The top end of the hard air suction pipe 21 extends from the top wall of the air duct 1 to the outside of the air duct 1. Air can be blown or sucked into the air duct 1 through the top end of the hard air suction pipe 21 exposed outside the air duct 1, and the height of the bottom end of the hard air suction pipe 21 inside the air duct 1 can be changed by pulling the hard air suction pipe 21.

[0032] The end of the rigid suction pipe 21 extending outside the air duct 1 is threadedly connected with a head 3, and the head 3 is a cylindrical structure with an opening toward the top of the rigid suction pipe 21. After the head 3 is threadedly connected to the rigid suction pipe 21, the top of the rigid suction pipe 21 is covered by the head 3. The end cap 3 has a plug 31 for plugging the rigid air suction pipe 21. The plug 31 is integrally formed on the internal end surface of the end cap 3 and extends toward the opening direction of the end cap 3. The plug 31 is interference fit with the top of the rigid air suction pipe 21. For example, the plug 31 is made of rubber. The end cap 3 is threadedly connected to the rigid air suction pipe 21 by twisting the end cap 3. The end cap 3 moves relative to the rigid air suction pipe 21 along the inclined direction of the filter screen 4. During the movement of the end cap 3, the plug 31 gradually approaches the top of the rigid air suction pipe 21 and abuts against the top of the rigid air suction pipe 21. Then, the plug 31 is immersed in the top opening of the rigid air suction pipe 21 and blocks the top opening of the rigid air suction pipe 21. Those skilled in the art should be able to imagine that there is also a sealing structure (not shown in the figure) between the rigid air suction pipe 21 and the air duct 1 for improving air tightness, such as a sealing strip or a labyrinth sealing structure between the rigid air suction pipe 21 and the air duct 1.

[0033] Reference Figure 1 and Figure 4 The dust box 22 is a box-shaped structure with closed ends and an open side, and moves horizontally inside the air duct 1 along with the hard air suction pipe 21. The opening of the dust box 22 faces and is close to the side of the filter 4 facing the air inlet direction. The end of the dust box 22 has a guide column 223 for extending into the inner wall of the air duct 1, for sliding along the inclined direction of the filter 4, and for engaging with the air duct 1 in the direction of gas flow. One end of the guide column 223 is fixed to the end face of the dust box 22, and the other end extends outward along the length direction of the dust box 22. A guide groove 11 for accommodating the guide column 223 is provided on the inner wall of the air duct 1 on the side of the filter 4 facing the air inlet direction. The guide groove 11 extends from the inner top wall of the air duct 1 to the inner bottom wall of the air duct 1 along the inclined direction of the hard suction pipe 21. The guide column 223 is inserted into the guide groove 11 and the guide column 223 is engaged with the air duct 1 in the direction of gas flow in the air duct 1 through the guide groove 11. The two end faces of the dust box 22 respectively abut the two inner walls of the air duct 1. By moving one end of the hard suction pipe 21 outside the air duct 1, the hard suction pipe 21 can drive the dust box 22 to move along the inclination direction of its own filter 4, so that the dust box 22 in a horizontal posture and close to the filter 4 passes completely through the windward surface of the filter 4, and the dust accumulated on the filter 4 is collected by an external negative pressure device connected to the hard suction pipe 21.

[0034] The two ends of the dust removal brush 23 are fixedly connected to the two ends of the dust collection box 22 respectively. The bristles of the dust removal brush 23 are perpendicular to the filter screen 4 and abut against the filter screen 4. The bristles of the dust removal brush 23 are deformed and bent under the abutment force of the filter screen 4. The top and bottom sides of the dust removal brush 23 are both provided with openings connected to the dust collection box 22. When the dust collection box 22 moves with the hard air suction pipe 21, the dust removal brush 23 scrapes the filter screen 4, so that the dust accumulated on the filter screen 4 can be more efficiently separated from the filter screen 4, and under the action of the external negative pressure device connected to the hard air suction pipe 21, the dust is discharged from the air duct 1 through the dust collection box 22 and the hard air suction pipe 21, completing the non-stop cleaning task of the filter screen 4.

[0035] The top wall of the air duct 1 is provided with a chamber for accommodating the dust removal assembly 2. Figure 1 and Figure 2 The inner wall of the air duct 1 extends toward the inner side of the outer wall of the air duct 1, forming a accommodating chamber 12 that can accommodate a dust box 22, a dust brush 23 and part of the hard suction pipe 21. The user can lift the hard suction pipe 21 to the highest position, so that the dust box 22 and the dust brush 23 are placed inside the accommodating chamber 12, so as to reduce the physical structure on the gas flow path inside the air duct 1, reduce the impact on the airflow size, and thereby reduce the impact on energy consumption.

[0036] In this embodiment, the hard suction pipe 21 is moved along the inclined direction of the filter 4, so that it drives the dust removal brush 23 and the dust collecting box 22 to move. During the downward movement of the dust removal brush 23, the dust accumulated on the filter 4 is swept off, and the swept off dust falls into the opening of the dust collecting box 22. The hard suction pipe 21 is connected with an external negative pressure device to allow the dust to be sucked out of the air duct 1. During the upward movement of the dust removal brush 23, the residual dust on the filter 4 is swept off the dust removal brush 23 and falls into the opening of the dust collecting box 22, and is sucked away by the external negative pressure device connected to the hard suction pipe 21, thereby completing the cleaning action of the filter 4.

[0037] In an exemplary embodiment of the present disclosure, referring to Figure 1 The opening of the dust box 22 includes a push-in dust suction port 222 and a drag-out dust suction port 221 separated by a dust removal brush 23. The opening direction of the push-in dust suction port 222 is set at an acute angle to the extension direction of the dust removal brush 23, and the opening direction of the drag-out dust suction port 221 is set at an acute angle to the extension direction of the dust removal brush 23.

[0038] For example, refer to Figure 1The dust removal brush 23 is located between the top and bottom sides of the opening of the dust box 22, and the drag-out dust suction port 221 is formed between the dust removal brush 23 and the top side of the opening of the dust box 22. As the hard suction pipe 21 is dragged out, the dust removal brush 23 moves from the bottom side of the filter 4 to the top side of the filter 4. During the movement, the dust removal brush 23 sweeps off the accumulated dust on the filter 4 and falls into the dust box 22 from the drag-out dust suction port 221; the push-in dust suction port 222 is located between the dust removal brush 23 and the bottom side of the opening of the dust box 22. As the hard suction pipe 21 is pushed in, the dust removal brush 23 moves from the top side of the filter 4 to the bottom side of the filter 4. During the movement, the dust removal brush 23 sweeps off the accumulated dust on the filter 4 and falls into the dust box 22 from the push-in dust suction port 222.

[0039] In an exemplary embodiment of the present disclosure, referring to Figure 1 The end of the hard suction pipe 21 is enlarged and has a plurality of shunt pipes 212 for connecting the dust box 22 from different positions on the dust box 22 , and the end of the shunt pipe 212 is located on one side of the bottom wall of the dust box 22 .

[0040] For example, refer to Figure 1 The bottom end of the hard suction pipe 21 is integrally formed with an expanded portion 211, which is connected to the hard suction pipe 21 and has an inner diameter larger than the inner diameter of the hard suction pipe 21. There are four shunt pipes 212, all of which are connected to the expanded portion 211. One end of the shunt pipe 212 is fixed to the outer wall of the expanded portion 211, and the other end of the shunt pipe 212 extends and is fixed to the side of the dust collecting box 22 away from the filter 4. The four shunt pipes 212 are evenly spaced along the length direction of the dust collecting box 22. The four shunt pipes 212 make the negative pressure inside the dust collecting box 22 more evenly distributed, so that the dust accumulated inside the dust collecting box 22 can be more efficiently and completely discharged from the air duct 1 through the expanded portion 211 and the hard suction pipe 21.

[0041] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
