Abstract
The invention discloses a dust-free angle grinder comprising an angle grinder body. The angle grinder body is provided with a semicircular protective cover, and the upper portion and the lower portion of the protective cover are in the shapes of the same semicircles; the angle grinder further comprises a dust collection box; an inlet pipe is arranged on one side of a dust collection box body; a centrifugal fan is arranged on the other side opposite to the inlet pipe; a filter element assembly is arranged in the dust collection box in the wind direction; the dust collection box is further provided with a box door; the closed end of the protective cover communicates with the inlet pipe through a connection hose; the upper portion and the lower portion of the protective cover are arranged into the shapes of the same semicircles; and the protective cover is made into a semi-closed type dust collection cavity with one side being a rectangular opening and the other side being an arc-shaped plate. The structure can guarantee that diffusion is avoided during dust collection, use of the angle grinder can also be guaranteed, and the normal cutting, grinding and polishing work of the angle grinder is not affected; and the dust-free angle grinder can avoid that dust pollutes the environment, and health of operators is guaranteed.
Description
Technical field
The present invention relates to electric tool technical field, specifically a kind of dustless angle grinder.
Background technology
Angle grinding machine is the conventional electric tool that a kind of disc wheel utilizing High Rotation Speed carries out cutting, polishing, polish.In use, a large amount of dust can be produced, on the one hand pollute environment, on the other hand also can affect the healthy of operating personnel.
Summary of the invention
It is an object of the invention to provide a kind of dustless angle grinder, the dust of generation operationally can effectively be collected by this angle grinding machine automatically, it is to avoid pollutes environment, it is ensured that the health of operating personnel, and does not affect the normal use of angle grinding machine.
The technical solution adopted for the present invention to solve the technical problems is:
Dustless angle grinder, including angle mill body, angle mill body is provided with the protective cover of semicircular in shape, the top of described protective cover and the semicircle that bottom is that shape is identical；Described angle grinding machine also includes that disposal box, the side of disposal box casing are provided with inlet tube, and the opposite side relative with inlet tube is provided with centrifugal blower；It is provided with element kit along wind direction inside disposal box, disposal box is additionally provided with chamber door；The blind end of described protective cover is connected with inlet tube by connecting flexible pipe.
Further, described element kit comprises filter element frame, Z-type HEPA screen pack and dust-filtering cotton, and described filter element frame is vertically fixed on disposal box inwall, and Z-type HEPA screen pack is sequentially fixed on filter element frame along wind direction with dust-filtering cotton.
The invention has the beneficial effects as follows, the top of protective cover is set to bottom the semicircle that shape is identical, making protective cover constitute side is rectangular aperture, and opposite side is the semi-enclosed dust-collecting cavity of arc；This structure both can guarantee that and will not spread when collecting dust, may insure that again the use of angle grinding machine, did not affect its cutting normally, polishing, polishing；During the grinding machine work of angle, open centrifugal blower, dust passes sequentially through protective cover, connects flexible pipe and inlet tube entrance disposal box, it is collected filtering to dust by element kit, avoid dust polluting environment, ensure the health of operating personnel, Z-type HEPA screen pack and dust-filtering cotton double-filtration, filter more thorough；Open chamber door and can clear up the dust of collection, easy to operate.
