Technical Field

The invention relates to a flying dust prevention foot pad.

Background

The foot pad is a common cleaning article in the vehicle, and is used for isolating and cleaning sundries and dust on the sole of the vehicle and keeping the interior of the vehicle clean. In the prior art, the surface of the foot pad can be enriched with dust after long-term use, and fly ash can be generated after the foot pad is used continuously, so that air suspended particles are increased.

Disclosure of Invention

The technical scheme adopted by the invention for solving the technical problems is as follows: a flying dust prevention foot pad comprises a hollow rubber pad, an elastic metal net and a braided fabric dust filtering ring, wherein the braided fabric dust filtering ring is wrapped around the elastic metal net, the elastic metal net is arranged in the hollow rubber pad and is filled with an inner cavity of the hollow rubber pad, a dust collecting groove array is arranged on the upper surface of the hollow rubber pad, a dust collecting hole is formed in the bottom of the dust collecting groove, the dust collecting hole is communicated with the inner cavity of the hollow rubber pad, a first disc-shaped rubber sheet is arranged at the lower end of the dust collecting hole, and the first disc-shaped rubber sheet is connected with an inner point of the hollow rubber pad; the hollow rubber gasket ring side is provided with a pressure relief hole, a second disc-shaped rubber sheet is arranged at an outlet of the pressure relief hole, and the second disc-shaped rubber sheet is connected with an external point of the hollow rubber gasket.

The utility model provides a prevent flying dust callus on sole, dust absorption hole and pressure release hole are big, the little two horn shape structures of middle internal diameter in both ends internal diameter.

A dust flying prevention foot pad is characterized in that a braided fabric dust filtering ring is arranged between an elastic metal net and a pressure relief hole.

A dust flying prevention foot pad is characterized in that burrs are arranged on the upper surface of a hollow rubber pad.

According to the invention, the dust retained on the surface of the foot pad is sucked and stored in the foot pad by utilizing the internal and external pressure difference generated by deformation of the rubber pad when the rubber pad is trodden, so that flying dust is reduced.

Drawings

The invention is further illustrated with reference to the following figures and examples.

Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following further description is made with reference to the accompanying drawings, and it is obvious that the following described drawings are only one embodiment of the present invention, and it is within the scope of the present invention for a person of ordinary skill in the art to obtain other embodiments based on the drawings and the embodiment without any creative effort.

A flying dust prevention foot pad comprises a hollow rubber pad 1, an elastic metal net 2 and a braided fabric dust filtering ring 3, wherein the braided fabric dust filtering ring 3 is wrapped around the elastic metal net 2, the elastic metal net 2 is arranged in the hollow rubber pad 1 and is filled in an inner cavity of the hollow rubber pad 1, a dust collecting groove 4 array is arranged on the upper surface of the hollow rubber pad 1, dust collecting holes 5 are formed in the bottom of the dust collecting groove 4, the dust collecting holes 5 are communicated with the inner cavity of the hollow rubber pad 1, a first disc-shaped rubber sheet 6 is arranged at the lower end of each dust collecting hole 5, and the first disc-shaped rubber sheet 6 is connected with inner points of the hollow rubber pad 1; the hollow rubber gasket 1 is provided with a pressure relief hole 7 at the ring side, a second disc-shaped rubber sheet 8 is arranged at the outlet of the pressure relief hole 7, and the second disc-shaped rubber sheet 8 is connected with the outer point of the hollow rubber gasket 1.

The dust absorption hole 5 and the pressure relief hole 7 are of a double-horn structure with large inner diameters at two ends and small inner diameter in the middle.

The braided fabric dust filtering ring 3 is arranged between the elastic metal net 2 and the pressure relief hole 7.

Burrs 9 are arranged on the upper surface of the hollow rubber gasket 1.

The working principle of the technical scheme is as follows: when the foot pad is trampled, the hollow rubber pad 1 is pressed and deformed, the internal pressure of the hollow rubber pad 1 is greater than the external pressure, the first disc-shaped rubber sheet 6 is pressed upwards to block the dust collection opening 5, and the second disc-shaped rubber sheet 8 is pressed outwards to open the pressure release hole 7 for pressure release; when the foot pad is not trampled, the elastic metal net 2 supports the hollow rubber pad 1 to recover deformation, the internal pressure of the hollow rubber pad 1 is smaller than the external pressure, the first disc-shaped rubber sheet 6 is subjected to the downward pressure large-opening dust suction opening 5, the second disc-shaped rubber sheet 8 is subjected to the inward pressure to seal the pressure relief hole 7, and dust enriched in the dust collection groove 4 enters the hollow rubber pad 1 along with the air flow.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
