[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The utility model provides an embodiment: a motor end cover with a detachable filter screen, comprising a motor end cover plate 1, mounting holes 13 are provided on both sides of the motor end cover plate 1, a filter frame 2 is nested inside the mounting holes 13, a blocking filter screen 3 is fixedly connected to the inside of the filter frame 2, a disassembly handle 6 is fixedly connected to the top middle of the filter frame 2, a mounting notch 11 is provided on the outside of the disassembly handle 6, a disassembly notch 12 is provided on the inner rear side of the mounting notch 11, a limit fixing assembly is installed on both sides of the motor end cover plate 1, a positioning sleeve 9 is fixedly connected to the top middle of the motor end cover plate 1, and the outer side of the positioning sleeve 9 is fixedly connected to the bottom of the filter frame 2. A sound reduction layer 10 is fixedly connected, a shaft protection component is installed on the inner side of the positioning sleeve 9, and the limit fixing component includes a limit arc slide groove 5 located on both sides of the motor end cover plate 1, and the interior of the limit arc slide groove 5 is slidably connected to the limit block 14, and the top of the limit block 14 is fixedly connected with a toggle arc piece 4, and the rear side of the toggle arc piece 4 is connected to the interior of the limit arc slide groove 5 through a spring 15. The inner sides of the limit blocks 14 are respectively correspondingly nested in the interior of the installation slot 11, and the outer dimensions of the limit blocks 14 are adapted to the inner dimensions of the disassembly slot 12, and the outer sides of the toggle arc pieces 4 are respectively correspondingly slidably connected to the tops of the limit arc slide grooves 5;

[0026] When too much dust accumulates on the outside of the blocking filter 3, when removing the blocking filter 3, the arc piece 4 is pulled backward, so that the bottom limit block 14 slides backward, and the inner side of the limit block 14 slides inside the installation slot 11. When the installation slot 11 moves to the top of the disassembly slot 12, the installation filter frame 2 is lifted upward by the disassembly handle 6, so that the blocking filter 3 and the top of the motor end cover plate 1 are disassembled, and the dusty filter is quickly disassembled to ensure stable operation of the motor.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The shaft protection assembly includes a rotating sleeve 8 located inside the positioning sleeve 9, a plurality of positioning soft rubber strips 7 are evenly fixedly connected to the inner side of the rotating sleeve 8, the upper and lower sides of the outer side of the rotating sleeve 8 are fixedly connected to the limiting ring 17, the outer side of the rotating sleeve 8 is evenly rotatably connected to the ball 16, the inner side of the positioning sleeve 9 is provided with a limiting ring groove 18 on both sides, and the inner side of the positioning sleeve 9 is provided with a plurality of limiting sliding grooves 19, the outer side of the limiting ring 17 is respectively correspondingly rotatably connected to the inner side of the limiting ring groove 18, and the outer side of the ball 16 is respectively correspondingly slidably connected to the inner side of the limiting sliding groove 19;

[0028] When the motor end cover is installed, the output shaft of the motor passes through the inner side of the rotating sleeve 8, and the positioning soft rubber strip 7 is deformed as the shaft is squeezed. The positioning soft rubber strip 7 squeezes and fixes the shaft, and as the shaft rotates, the rotating sleeve 8 is driven to rotate. The rotation of the rotating sleeve 8 drives the limiting ring 17 to rotate inside the limiting ring groove 18, and the ball 16 slides inside the limiting groove 19. The ball 16 rotates inside the rotating sleeve 8, thereby further reducing the friction generated by the rotation of the rotating sleeve 8, thereby protecting the shaft, avoiding direct contact between the shaft and the inner wall during rotation, thereby causing wear of the shaft and ensuring the service life of the shaft.

[0029] Working principle: When the motor end cover is installed, the output end shaft of the motor passes through the inner side of the rotating sleeve 8, and the positioning soft rubber strip 7 squeezes and fixes the shaft. As the shaft rotates, the rotating sleeve 8 is driven to rotate. The rotation of the rotating sleeve 8 drives the limit ring 17 to rotate inside the limit ring groove 18, and the ball 16 slides inside the limit slide groove 19. The ball 16 rotates inside the rotating sleeve 8. When too much dust accumulates on the outside of the blocking filter 3, when disassembling the blocking filter 3, the arc piece 4 is pulled backward, so that the bottom limit block 14 slides backward, and the inner side of the limit block 14 slides inside the installation slot 11. When the installation slot 11 moves to the top of the disassembly slot 12, the installation filter frame 2 is lifted upward by the disassembly handle 6, so that the blocking filter 3 and the top of the motor end cover plate 1 are disassembled.
