An electric drill dust removal device

Abstract

The invention discloses an electric drill dust removing device. The electric drill dust removing device comprises a dust hood (1), a cyclone dust removing box (3) and a fan case (4); a first elastic hose (21) is arranged in the middle of the dust hood (1) and communicated with an air outlet formed in the front face of the fan case (4), a second elastic hose (22) is arranged on the lower portion of the dust hood (1) and communicated with an air inlet pipe (32) of the cyclone dust removing box, an air outlet pipe (31) arranged on the upper portion of the cyclone dust removing box is communicated with an air inlet formed in the lower portion of the fan case (4), a filter screen (6) is installed at the air inlet of the fan case (4), a shaft hole connected with the head of a perforating machine (8) in a sleeving mode is formed in the center of the back face of the fan case (4), a drill bit (9) penetrates through the shaft hole from the dust hood (1) through the first elastic hose (21) and the fan case (4) to be connected to the head of the perforating machine (8), and a fan (5) in the fan case (4) is fixed on a tail rod of the drill bit (9) through a spring clamping device (10). The electric drill dust removing device has the advantages that dust removing is achieved, and dust is deposited in the cyclone dust removing box.

Description

technical field [0001] The invention belongs to an electric drill auxiliary tool, in particular to an electric drill dust removal device. Background technique [0002] When electric drills are used to drill holes in the wall, a large amount of dust is generated, which pollutes the home improvement environment. At the same time, decoration workers inhale a large amount of dust during work, causing occupational diseases such as pneumoconiosis. [0003] Chinese patent document CN 104907307 A disclosed an electric drill vacuum cleaner on September 16, 2015. It includes a dust collection cover, a dust suction pipe, a fan, and a dust collection pipe. The dust collection pipe includes a wind chamber, a dust collection part, and a cover. The wind chamber is set as a cylindrical structure. The wind chamber is provided with a drill chuck through hole. The fan is arranged in the wind chamber, and the drill chuck used for rotation drives the fan; The parts are arranged in a cylindrical...

AI Technical Summary

Problems solved by technology

[0009] The present invention returns to the fan box from the fan box, the first elastic hose, the dust suction hood, the second elastic hose, the cyclone dust removal box, and forms a relatively closed airflow circulation path, which not only overcomes the problem of the air flow caused by the wind in the prior art. There is no way out of the room, and the dust gas is kept from leaking out; at the same time, the air inlet of the fan box is equipped with a filter screen, so that the granular dust is blocked and stays inside the cyclone dust removal box
