[0021] Embodiments of the present utility model, for example Figures 1 to 5As shown in the figure, a filter that is convenient for installation and disassembly includes a base 1 and a filter body 4. The top end of the base 1 is provided with an inverted T-shaped base groove 10 that extends in the front-rear direction. The front side wall of the base groove 10 is an open structure. The base 1 is provided with a cavity directly below the base groove 10. A horizontal gear 2 is rotatably arranged in the cavity of the base 1. The gear 2 is located directly below the center of the base groove 10. A groove is provided on the inner bottom surface of the cavity of the base 1. A rotating shaft is provided at the center of the bottom end of the gear 2, and the rotating shaft is inserted into the groove. A bearing is provided between the groove and the rotating shaft. A first rotating member 3 is provided at the top end of the gear 2. The top surface of the first rotating member 3 is coplanar with the bottom of the base groove 10. A first guide rail 30 is provided at the top end of the first rotating member 3. A rack 31 that meshes with the gear 2 is provided in the cavity. A cavity sliding groove 12 is provided on the right side wall of the cavity of the base 1. The extending direction of the cavity sliding groove 12 is perpendicular to the axis of the gear 2, that is, the cavity sliding groove 12 extends in the front-rear direction. The rack 31 is slidably arranged in the cavity sliding groove 12 in a matching manner. The front end of the rack 31 is provided with a connecting rod 32 that passes through the side wall of the base 1. A spring 33 for resetting the rack 31 is sleeved on the connecting rod 32. The front and rear ends of the spring 33 are respectively connected to the front end of the rack 31 and the front inner side wall of the cavity. The filter body 4 is slidably arranged in the base groove 10 in a matching manner. Extension plates 41 adjacent to the filter body 4 extend from both the left and right side walls of the filter body 4. The filter body 4 and the two extension plates 41 form an inverted T-shaped structure. The filter body 4 is slidably arranged in the base groove 10 through the two extension plates 41 in a matching manner. A main body sliding groove 40 for the first guide rail 30 to slide in a matching manner is provided at the bottom end of the filter body 4. A second rotating member 42 is rotatably arranged at the bottom end of the filter body 4. The bottom surface of the second rotating member 42 is coplanar with the bottom surface of the filter body 4. A guide rail sliding groove 43 for the first guide rail 30 to slide into is provided on the bottom surface of the second rotating member 42.

[0022] By pulling the connecting rod 32, the rack 31 drives the gear 2 to rotate, making the first guide rail 30 on the first rotating member 3 perpendicular to the opening, that is, making the first guide rail 30 extend in the front-back direction. Subsequently, rotate the second rotating member 42 at the bottom end of the filter body 4 so that the length direction of the guide rail chute 43 is the same as the length direction of the first guide rail 30, that is, making the guide rail chute 42 also extend in the front-back direction. Then slide the filter body 4 from the opening into the base groove 10. The first guide rail 30 slides through the main body chute 40 and then slides into the guide rail chute 43. After the first guide rail 30 completely slides into the guide rail chute 43, release the connecting rod 32. The rack 31 resets under the action of the spring 33, making the first guide rail 30 and the guide rail chute 43 rotate 90°, that is, both the first guide rail 30 and the guide rail chute 43 extend in the left-right direction. At this time, the first guide rail 30 and the guide rail chute 43 prevent the filter body 4 from sliding out of the front opening, and the inverted T-shaped base groove 10 prevents the filter body 4 from falling out when the filter is installed on the side wall or the inner top surface. That is, the filter body 4 can be quickly disassembled and assembled, which is very convenient.

[0023] Further improvements, such as Figure 2 and Figure 3 shown in, the first rotating member 3 is of a cylindrical structure. The base 1 is provided with a circular base through hole directly above the gear 2. The first rotating member 3 is inserted into the base through hole in a matching manner. The first guide rail 30 passes through the center of the top surface of the first rotating member 3. The bottom of the base groove 10 is provided with a second guide rail 5. The second guide rail 5 extends from the first rotating member 3 to the opening of the base groove 10, that is, the second guide rail 5 extends in the front-back direction. The axis of the second guide rail 5 passes through the center of the top surface of the first rotating member 3. The second guide rail 5 is slidably arranged in the main body chute 40 in a matching manner. During the process of the filter body 4 sliding into the base groove 10, the second rotating member 42 slides on the second guide rail 5 through the guide rail chute 43. At this time, the second guide rail 5 prevents the second rotating member 42 from rotating, making the first guide rail 30 slide into the guide rail chute 43 more smoothly.

[0024] Further improvements, such as Figure 1 and Figure 5 shown in, the base 1 is provided with a quarter-circular arc groove 6 on the inner bottom surface of the cavity. The arc groove 6 is located directly below the gear 2. The bottom end of the gear 2 is provided with a limiting rod 60 that is inserted into the arc groove 6 in a matching manner. Through the limiting rod 60 and the arc groove 6, the rotation of the first rotating member 3 will not exceed 90°, making the first guide rail 30 easier to align with the main body chute 40 and the guide rail chute 43.

[0025] Further improvements, such as Figure 1 and Figure 2 shown in, a pull ring 7 is provided at the end of the connecting rod 32 that passes through the base 1, which is convenient for pulling the connecting rod 32.

[0026] Further improvements, such as Figure 2 and Figure 3 As shown in Figure 3 , mounting plates 11 are provided at both left and right ends of the base 1 adjacent to the bottom end of the base 1. The mounting plates 11 extend in the front-rear direction. Mounting plate through-holes 110 are provided on the mounting plates 11. Two mounting plate through-holes 110 are provided on each mounting plate 11, and the two mounting plate through-holes 110 are spaced apart in the front-rear direction. The installation of the base 1 is facilitated through the mounting plates 11 and the mounting plate through-holes 110.
