[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] Example 1: Reference Figures 1-9 An anti-clogging sensor includes: a blocking net 2 mounted on a front cover 13 of a sensor body 1, one end of the blocking net 2 being open and used to block foreign matter from entering the front cover 13; a second fixing ring 31 fixedly connected to the sensor body 1; an outer cover 3 rotatably mounted on the second fixing ring 31; a brush 43 mounted on an inner wall of the outer cover 3, and when the outer cover 3 is rotated, the brush 43 performs a circular cleaning on the blocking net 2;

[0027] The second fixing ring 31 is fixedly connected to the first fixing ring 22. The first fixing ring 22 is symmetrically provided with an arcuate groove 23. The upper surface of the first fixing ring 22 is provided with a first through-groove 24. The first through-groove 24 is connected to the arcuate groove 23. The outer periphery of the open end of the barrier net 2 is fixedly connected to the first locking block 21. The first locking block 21 is locked in the arcuate groove 23 through the first through-groove 24.

[0028] An annular groove 311 is provided on the inner circumference of the second fixing ring 31, and a second through groove 312 is symmetrically provided on the upper surface of the second fixing ring 31. The second through groove 312 is communicated with the annular groove 311. A second locking block 33 is symmetrically fixedly connected to the outer circumference of one end of the outer cover shell 3, and the second locking block 33 is rotatably connected in the annular groove 311 through the second through groove 312.

Then, the barrier net 2 is pushed downward so that the first locking block 21 enters the arc-shaped groove 23. Then, the barrier net 2 is rotated so that the first locking block 21 is locked on the first fixing ring 22 through interference fit.

[0031] Then, the outer cover 3 is placed on the barrier net 2. The inner diameter of the outer cover 3 is larger than the outer diameter of the barrier net 2, so there is a certain distance between the outer cover 3 and the barrier net 2. The second locking block 33 on the outer cover 3 is aligned with the second through-groove 312, and the outer cover 3 is rotated so that the second locking block 33 rotates in the annular groove 311. During use, the second locking block 33 is misaligned with the second through-groove 312 to prevent the outer cover 3 from falling off.

[0032] When the barrier net 2 needs to be cleaned, the outer cover shell 3 is rotated and the brush 42 on the inner wall of the outer cover shell 3 cleans the barrier net 2 for a circle, brushing off foreign matter on the barrier net 2. In addition, the outer cover shell 3 can be disassembled and the barrier net 2 can be disassembled for separate cleaning.

[0035] By inserting the dovetail block 42 into the dovetail groove 4 , the mounting plate 41 and the outer cover shell 3 are quickly connected, thereby facilitating the installation or removal of the brush 42 .

[0036] A discharge groove 34 is provided on the outer periphery of the open end of the outer cover shell 3, and the discharge groove 34 is located at the dovetail groove 4. Through the opened discharge groove 34, while the brush 42 is cleaning the barrier net 2, the foreign matter brushed off can be discharged through the discharge groove 34 in time, thereby realizing the convenient and quick cleaning of the sensor body 1.

[0037] The sensor body 1 is provided with an external thread 11, and a polygonal block 12 is fixedly connected to the sensor body 1;

[0038] The external thread 11 can facilitate the quick connection of the sensor body 1 to the installation position, and the polygonal block 12 can facilitate the use of a wrench to tighten the sensor body 1.

[0039] The utility model is provided with a blocking net 2 and an outer cover shell 3. When the blocking net 2 needs to be cleaned, the outer cover shell 3 is rotated, and the brush 42 on the inner wall of the outer cover shell 3 cleans the blocking net 2 for a circle, and foreign matter on the blocking net 2 is brushed off. In addition, the outer cover shell 3 can be disassembled, and then the blocking net 2 can be disassembled for separate cleaning.
