Detailed Description

The embodiments of the present invention will be described in detail below with reference to the above drawings.

As shown in fig. 1-5, 1 is a filter cover, 11 is an air inlet, 12 is a convex ring, 2 is a dust sleeve, 3 is a connecting ring, 4 is a pull rod, 41 is a pinch grip, 5 is a collision block, 6 is an elastic element, 7 is a rotary buckle, 8 is a buckle, 9 is a support, 91 is a guide pipe, and 10 is a dust cylinder.

A self-cleaning dust filtering cover of a dust collector is mainly used as an important filtering part in a dust barrel of the dust collector and structurally comprises a filtering cover 1, a through air inlet 11 is arranged on the filtering cover, particularly the middle part of the filtering cover, a support 9 is arranged in the air inlet, the support is composed of a guide pipe 91 in the middle part and a plurality of spokes which are uniformly distributed on the periphery of the guide pipe in a radial shape and are used for supporting and fixing the guide pipe 91, and the axial lead of the guide pipe 91 is just overlapped with the axial lead of the air inlet 11.

Simultaneously, still install dirt cover 2 on filter mantle 1 and close air intake 11 with the cover, this dirt cover is made for taking filtering capability's material, like soft non-woven fabrics or the sea handkerchief of stereoplasm to and the filtering material of various soft or hard materials is all gone, and the port detachable connection of dirt cover 2 is on filter mantle 1, specifically is: the port department of the dust cover 2 is sewed with the connecting ring 3 made of hard material, the filtering cover 1 is provided with a convex ring 12 whose circumference encloses the air inlet 11, the convex ring is a connected part on the filtering cover 1, a rotary buckle 7 is arranged between the inner circumferential surface of the connecting ring 3 and the outer circumferential surface of the convex ring 12, when the connecting ring 3 is installed on the convex ring 12 in place, the rotary buckle 7 between the inner circumferential surface of the connecting ring 3 and the outer circumferential surface of the convex ring 12 can be driven to form a buckle by rotating the connecting ring 3 at a proper position, at the moment, the dust cover 2 can be connected and fixed on the filtering cover 1 without being detached, and the connecting ring 3 can be detached from the convex ring 12 according to the reverse rotation direction of the connection, thereby realizing the detachable connection of the dust cover 2 and facilitating the cleaning and replacing of the dust cover 2 by users.

The dust sleeve 2 is internally provided with a pull rod 4, the front end of the pull rod is provided with a collision block 5 which is fixedly installed, the rear end of the pull rod 4 is backwards movably inserted into a guide pipe 91 of the air inlet 11 to be guided and then exposed and is provided with a pinch handle 41, and the pinch handle can help fingers to operate the pull rod 4 better.

And, still there is elastic element 6 of suit outside the tie rod 4, this elastic element is a conical spring, and make the big end elasticity of the conical spring push against on the filter mantle 1, the small end elasticity pushes against on hitting the block 5, so tie rod 4 and hitting the block 5 and can be pushed forward by the elasticity at the same time under the normal state, thus push and hit the block 5 to contact the bottom of the dust cover 2 elastically.

Therefore, after the pull rod 4 is pulled backwards to compress the elastic element 6 to form elastic energy storage, once the pull rod 4 is released, the elastic element 6 can be used for recovering the released elasticity to push the collision block 5 to collide and vibrate the dust cover 2, so that the dust adhered to the outer surface of the dust cover 2 is shaken off to finish the self-cleaning of the dust cover, the elastic structure also plays a role in stretching the dust cover 2, and the trouble that a stretching support needs to be additionally installed in the traditional dust cover is omitted.

In addition, the outer circumferential surface of the filter cover 1 is provided with a buckle 8, the filter cover 1 can be detachably arranged in the dust cylinder 10 through the buckle 8, and the buckle 8 can also facilitate the installation and fixation of the dust cover so as to prevent the whole dust cover from being accidentally taken out of the dust cylinder 10 when the pull rod 4 is pulled.

Obviously, the cleaning method of self-cleaning without detaching the dust cover from the dust cylinder 10 is simpler than the traditional cleaning method of detaching the dust cover, and brings great convenience to users.

The above description is only a specific embodiment of the present invention, and those skilled in the art should understand that any similar structural design to the embodiment is included in the protection scope of the present invention.
