Abstract

The purpose of the present invention is to easily remove foreign materials from shoes by an upper plate, which horizontally vibrates by a vibration motor, and to easily separate and suck dust even at low suction power by transferring the dust toward a suction inlet by means of a lower plate which is downwardly inclined in the direction of the suction inlet. According to the present invention, provided is a dust suction device for shoes, comprising: a suction unit configured in such a manner that suction inlets of through-holes formed on the upper surface of a sealed housing are opened by an opening/closing unit which elastically descends whenever pressure is generated in the shoes; a suction device configured to operate a motor by receiving power to draw dust into the housing through the opened suction inlet and suck the dust through an inlet pipe, wherein an outlet pipe and the inlet pipe of the housing are connected to each other; and a vibration device configured to operate the vibration motor by receiving power to horizontally vibrate a portion of the suction unit which is in contact with the shoes, thereby separating foreign materials from the shoes, wherein the vibration device is connected to the suction unit.

Abstract

The present invention relates to a dust suction device for shoes which is provided on the floor in the entrance/exit of a facility where contamination from external contaminant sources must be prevented, such as some types of factories and hospitals, and which is adapted so as to more effectively suck in and remove dust and the like sticking to the bottoms of the shoes of people entering/exiting. The present invention is a dust suction device for shoes, comprising a housing formed with a plurality of suction holes at predetermined intervals in the upper part, a suction device provided so as to transmit a suction force to the inside of the housing and thereby suck detritus such as dust from the suction holes, and a resilient operational member provided so as to be able to open and close each of the suction holes formed in the housing and thereby selectively transmit the suction pressure being transmitted from the suction device; wherein, a plurality of adjacent resilient operational members from among the resilient operational members on the underside of the housing are collected together into a single group via a unit binding means, and, upon pressing one of the resilient operational members among the resilient operational members bound together via the unit binding means, the other surrounding resilient operational members also operate at the same time.
