[0025] 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.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an air filter element with a self-cleaning function, including a filter element body 1, a motor 2 is fixedly connected to the outside of the filter element body 1, a threaded rod 4 is fixedly connected to the output end of the motor 2, a threaded sleeve 5 is threadedly connected to the outside of the threaded rod 4, cleaning components 6 are fixedly connected to the outside of the threaded sleeve 5, two sliding rods 7 are fixedly connected to the inside of the filter element body 1, a collecting box 3 is slidably connected to the bottom of the filter element body 1, and clamping components 9 are arranged at the four corners inside the collecting box 3.

[0027] Specifically, the motor 2 is fixed by the filter element body 1 to prevent the motor 2 from shaking during operation, which may cause the expected effect of the device to fail to be achieved. The motor 2 drives the threaded rod 4 to rotate, and then the threaded sleeve 5 slides along the sliding rod 7, thereby driving the cleaning components 6 connected on both sides to clean the surface of the filter element body 1, so that the filter element body 1 can have a self-cleaning effect, thereby avoiding clogging of the filter element, thereby extending the service life of the filter element, and making it unnecessary for users to disassemble the filter element for cleaning, thereby reducing the user's maintenance work. The cleaned dust is collected by the collection box 3 at the bottom and then processed uniformly to avoid secondary pollution caused by dust dispersion, and the collection box 3 is installed by the snap-on component 9, which can be easily disassembled and the dust can be processed.

[0028] Reference Figure 4 The cleaning assembly 6 includes a sleeve rod 601, which is fixedly connected to the outside of the threaded sleeve 5, and a spring 602 is fixedly connected to the inside of the sleeve rod 601. The other end of the spring 602 is fixedly connected to a push rod 603, and the other end of the push rod 603 is fixedly connected to a brush 604; the inside of the sleeve rod 601 is slidably connected to the outside of the push rod 603, and the outside of the brush 604 fits the surface of the filter element body 1.

[0029] Specifically, the sleeve rod 601 is fixed by the threaded sleeve 5, and the spring 1 602 inside the sleeve rod 601 pushes the push rod 603 to slide, so that the brush 604 is in close contact with the surface of the filter element body 1, so that the dust on the surface of the filter element can be removed, and one end of the spring 1 602 is fixed to the inside of the sleeve rod 601, and the other end is fixed to the push rod 603, so that the pushing effect of the spring 1 602 is stable. The brush 604 is made of flexible material and will not cause damage when removing dust from the surface of the filter element.

[0030] Reference Figure 5 and Figure 6 The clamping assembly 9 includes a limiting groove 901, which is provided at the four inner corners of the collecting box 3. A slider 902 is slidably connected inside the limiting groove 901, a pull rod 904 is fixedly connected to one side of the slider 902, a spring 903 is sleeved outside the pull rod 904, a clamping block 905 is fixedly connected to the other side of the slider 902, and two clamping grooves 906 are provided on the left and right sides of the collecting box 3; one end of the spring 903 is fixedly connected to the outside of the slider 902, and the other end of the spring 903 is fixedly connected to the inner wall of the limiting groove 901; the longitudinal section of the clamping block 905 is set to be square, and the outside of the clamping block 905 and the inside of the clamping groove 906 are plug-in fit.

[0031] Specifically, the movement of the pull rod 904 can drive the slider 902 to slide inside the limiting groove 901, thereby causing the spring 2 903 to contract, and the slider 902 drives the card block 905 to move toward the inside of the limiting groove 901 and disengage from the card slot 906. Repeating the same operation can disassemble all the card components 9 at the four corners of the collection box 3, and then remove the collection box 3, which is convenient for unified treatment of the collected dust and reduces the user's treatment frequency. The two ends of the spring 2 903 are respectively connected to the outside of the slider 902 and the inner wall of the limiting groove 901, so that the spring 2 903 is more stable when extended and retracted, ensuring that the effect of the structural operation can be achieved. The longitudinal section of the card block 905 is set to a square, so that the card block 905 and the card slot 906 are more firmly inserted, which has a better fixing effect on the collection box 3.

[0032] Reference Figure 3 and Figure 4 Two strip holes 8 are provided on both sides of the bottom of the filter element body 1, and the strip holes 8 are arranged directly below the brush 604; the outsides of the two sliding rods 7 are slidably connected to the inside of the threaded sleeve 5, and the other end of the threaded rod 4 is rotatably connected to the inside of the collection box 3.

[0033] Specifically, the cleaned dust falls into the collecting box 3 through the strip hole 8, avoiding secondary pollution caused by the dust dispersion, thereby ensuring the filtering effect of the filter element. The two sliding rods 7 guide the movement of the threaded sleeve 5, so that the threaded sleeve 5 can move forward when the threaded rod 4 rotates, thereby driving the cleaning component 6 to clean the surface of the filter element body 1, preventing dust clogging from causing clogging of the filter element, thereby affecting the filtering effect.

[0034] Working principle: When cleaning the filter element body 1, first start the motor 2, and drive the threaded rod 4 to rotate through the motor 2, so that the threaded sleeve 5 slides along the sliding rod 7, thereby driving the cleaning component 6 to clean the surface of the filter element body 1, and the sleeve rod 601 is driven to move through the threaded sleeve 5, and the push rod 603 is pushed through the spring 602 connected inside it, so that the brush 604 is in close contact with the surface of the filter element body 1, and the dust on the surface is swept away while moving, so as to achieve the effect of automatic cleaning, avoid filter element clogging, thereby extending the service life of the filter element, so that users do not need to disassemble the filter element for cleaning, and reduce the user's maintenance work. The cleaned dust enters the collection box 3 through the strip hole 8 at the bottom of the filter body 1. By pulling the pull rods 904 on both sides of the collection box 3, the slider 902 slides inside the limit groove 901, causing the spring 903 to contract. At the same time, the slider 902 drives the block 905 to disengage from the groove 906. Repeating the above steps can remove the collection box 3 from the bottom of the filter body 1, thereby facilitating the centralized processing of the collected dust and preventing the cleaned dust from floating into the air and causing secondary pollution.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
