[0027] See also Figure 1-5The utility model provides a self-cleaning filter, including a filter body 1, the filter body 1 also includes a mounting frame 2, the mounting frame 2 is arranged on the outside of the filter body 1, a positioning frame 3 is fixed to the inner side wall of the mounting frame 2, one side of the filter body 1 is in contact with the positioning frame 3, one side of the mounting frame 2 is provided with a mounting component 4 adapted to the filter body 1, two symmetrically distributed bearing seats 5 are fixed to the side wall of one side of the mounting frame 2, and a cleaning component 6 adapted to the filter body 1 is provided on one side of the bearing seat 5.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth specifically explaining that the mounting assembly 4 includes a mounting groove 41, and a plurality of mounting grooves 41 are provided. The plurality of mounting grooves 41 are symmetrically distributed and opened on the inner side wall of the mounting frame 2. A matching extrusion plate 42 is slidably connected inside the mounting groove 41, and a side wall of one side of the extrusion plate 42 is in contact with the filter body 1, and a connecting rod 43 is fixed to a side wall of one side of the extrusion plate 42. A side wall of one side of the connecting rod 43 is slidably penetrated and arranged with a side wall of one side of the mounting frame 2, and a pull ring 44 is fixed to one end of the connecting rod 43. A spring 45 is sleeved on the outer surface of the connecting rod 43, one end of the spring 45 is fixed to the pull ring 44, and the other end of the spring 45 is fixed to the side wall of one side of the mounting frame 2. Through the setting of the mounting assembly 4, the positioning of the filter body 1 is accurately and effectively completed, and it is more convenient for the staff to install the filter body 1, and the installation work of the filter body 1 can be completed in a short time, and it is convenient to disassemble and replace the filter in the later stage, and it is more practical.

[0029] Further as Figure 5 As shown, it is worth explaining in detail that the length of the extrusion plate 42 is consistent with the opening length of the installation groove 41, and the side of the extrusion plate 42 away from the filter body 1 is set in a smooth arc surface. Through the setting of the extrusion plate 42, it is ensured that the filter body 1 and the extrusion plate 42 are in a relatively smooth and stable state during contact and extrusion transmission, which has a better installation and positioning effect on the filter body 1.

[0030] This scheme has the following working process: when the filter body 1 needs to be installed for use, first align the filter body 1 with the position of the installation frame 2, and use one side of the filter body 1 to contact the extrusion plate 42, so that the extrusion plate 42 is forced to move into the installation groove 41 until the filter body 1 is in contact with the positioning frame 3, and the elastic effect of the spring 45 is used to make the extrusion plate 42 rebound and reset under force, thereby completing the installation and positioning work of the filter body 1. When the filter body 1 needs to be cleaned, the reciprocating screw 64 is driven by the driving motor 69 to rotate synchronously, and the threaded transmission effect between the reciprocating screw 64 and the reciprocating wire sleeve 63 is used to make the rotating shaft 62 move after being forced, and the meshing transmission effect between the spur gear 66 and the toothed plate 67 is used to make the rotating shaft 62 rotate when performing parallel motion, driving the brush roller 65 to operate synchronously, and the brush roller 65 cleans the filter body 1, thereby achieving the purpose of cleaning the filter body 1.

[0031] According to the above working process, it can be known that the setting of the installation component 4 can accurately and effectively complete the positioning of the filter body 1. It is more convenient for the staff to install the filter body 1, and the installation of the filter body 1 can be completed in a short time. It is also convenient for the later disassembly and replacement of the filter, and it is more practical. Through the setting of the cleaning component 6, the impurities blocked in the filter body 1 can be stably cleaned, thereby ensuring that the filter body 1 is in a long-term and effective filtering state, which has good protection for the filter body 1 and effectively prevents the filter body 1 from being unable to filter normally due to blockage.

[0032] Further as Figure 3 and Figure 4 As shown, it is worth specifically explaining that the cleaning component 6 includes a through slot 61, two through slots 61 are provided, and the two through slots 61 are symmetrically distributed and opened on the side wall of one side of the installation frame 2, and the two through slots 61 are slidably connected to the rotating shaft 62, and one end of the rotating shaft 62 is rotatably connected to the reciprocating wire sleeve 63, and the two bearing seats 5 are rotatably connected to the reciprocating screw rod 64, and the reciprocating screw rod 64 is threadedly connected to the reciprocating wire sleeve 63, and the outer surface of the rotating shaft 62 is tightly sleeved with a brush roller 65; a spur gear 66, which is tightly sleeved on the outer surface of the rotating shaft 62, and the side wall of one side of the installation frame 2 A toothed plate 67 is fixed, and a spur gear 66 is meshedly connected with the toothed plate 67. A bracket 68 is fixed to a side wall of one side of the mounting frame 2, and a driving motor 69 is fixed to a side wall of one side of the bracket 68. One end of the output shaft of the driving motor 69 is coaxially fixed to one end of the reciprocating screw 64. Through the setting of the cleaning component 6, the impurities blocked in the filter body 1 can be stably cleaned, thereby ensuring that the filter body 1 is in a long-term and effective filtering state, which has good protection for the filter body 1 and effectively prevents the filter body 1 from being unable to filter normally due to blockage.

[0033] Further as Figure 2 As shown, it is worth explaining in detail that the outer surface of the brush roller 65 is in contact with one side of the filter body 1, and the length of the reciprocating screw 64 is greater than the opening length of the through slot 61. By setting the length of the reciprocating screw 64 and the through slot 61, it is possible to avoid the reciprocating wire sleeve 63 moving too far and causing it to be disconnected from the reciprocating screw 64.

[0034] Further as Figure 3 As shown, it is worth explaining in detail that the central axis of the positioning frame 3 is aligned with the central axis of the mounting frame 2, and two symmetrically distributed rollers 7 are tightly sleeved on the outer surface of the rotating shaft 62, and the rollers 7 are in contact with the positioning frame 3. By setting the rollers 7, the stability of the rotating shaft 62 when subjected to force translation can be greatly improved, thereby effectively avoiding the situation where the rotating shaft 62 moves unstably.

[0035] In summary: through the setting of the extrusion plate 42, it is ensured that the filter body 1 and the extrusion plate 42 are in a relatively smooth and stable state when contacting and extruding the transmission, which has a good installation and positioning effect on the filter body 1, and through the length setting of the reciprocating screw 64 and the through groove 61, it can avoid the reciprocating wire sleeve 63 moving too far and causing the reciprocating screw 64 to be disconnected, and through the setting of the roller 7, it can greatly improve the stability of the rotating shaft 62 when it is subjected to force translation, thereby effectively avoiding the unstable movement of the rotating shaft 62.
