Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In this application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1 to 4, the present invention provides a highly effective dustproof structure for grinding artificial teeth, which comprises a housing 10, a dust suction pipe 20, an air vent 30 and a dust collection base 40. The shell 10 is in threaded connection with the dust collecting seat 40, a motor 11, a storage battery 12 for supplying power to the motor 11 and a charger 13 for charging the storage battery 12 are installed in the shell 10, and the output end of the motor 11 is fixedly connected with the grinding wheel 111. One end of the dust suction pipe 20 is close to the grinding wheel 111, and the other end is communicated with the vent hole 30. An air compressor 41 is installed in the dust collection seat 40, a dust collection cavity cleaning mechanism 60 communicated with the vent hole 30 is arranged, and the dust collection cavity cleaning mechanism 60 is separated from the air compressor 41 through a filter screen 43. The dust collecting base 40 has an end face provided with an exhaust hole 44 for exhausting air from the air compressor 41.

When the denture polishing device polishes the denture, the air compressor 41 starts to work, so that negative pressure is formed in the dust collection cavity cleaning mechanism 60, and dust generated during polishing is sucked into the dust collection cavity cleaning mechanism 60 through the dust suction pipe 20 and the vent hole 30 to be stored. After repeated use, part of dust can adhere to the inner wall of the vent hole 30 and even cause the vent hole 30 to be blocked.

Specifically, the vent hole cleaning mechanism 50 includes a first scraper 51, a slider 52, and a connecting rod 53. The inner wall of the left end of the vent hole 30 is provided with a holding groove 31, and the first scraper 51 is arranged in the holding groove 31 so as not to influence the normal operation of the grinding device. The inner wall of the dust collection cavity cleaning mechanism 60 is provided with an annular groove 45, the sliding block 52 is arranged in the annular groove 45, the left and right extension length of the annular groove 45 is greater than that of the sliding block 52, and therefore the sliding block 52 can slide left and right in the annular groove 45. The connecting rod 53 is positioned in the vent hole 30, and one end of the connecting rod 53 is fixedly connected with the first scraper 51, and the other end is fixedly connected with the slider 52.

When clearing up dust collection chamber clearance mechanism 60, the workman rotates dust collection seat 40, makes dust collection seat 40 and casing 10 separate, then outwards pulls out connecting rod 53, and connecting rod 53 drives first scraper blade 51 and moves together for the dust of adhesion is scraped off on the air vent 30 inner wall, accomplishes the clearance to air vent 30. After cleaning, the first scraper 51 is firstly placed in the vent hole 30, then the dust collection base 40 is rotated, so that the dust collection base 40 is in threaded connection with the shell 10, at the moment, the sliding block 52 slowly slides rightwards in the annular groove 45 along the circumferential direction, and the movement track is in a spiral line shape. Preferably, the sliding block 52 has a certain friction with the inner wall of the annular groove 45, so as to prevent the sliding block 52 from being too loose in the annular groove 45 when the dust collection base 40 is separated from the housing 10, and further, the first scraper 51 and the vent hole 30 are difficult to align when the dust collection base 40 is connected with the housing 10, and the connection rate is not affected.

In one embodiment, a dust collection chamber cleaning mechanism 60 is also included, the dust collection chamber cleaning mechanism 60 including a second scraper 61 and a rotating handle 62. The second scraper 61 is rotatably connected with the filter screen 43 through a bearing, the outer surface of the second scraper is attached to the inner wall of the dust collecting seat 40, and the rotating handle 62 is fixedly connected with the middle part of the inner surface of the second scraper 61 and used for driving the second scraper 61 to rotate. After the dust collection seat 40 is separated from the shell 10, the worker rotates the rotating handle 62 for one circle, the second scraper 61 can scrape off the inner wall of the dust collection cavity cleaning mechanism 60, the operation is simple, and the cleaning efficiency of the dust collection cavity cleaning mechanism 60 is improved.

In one embodiment, the end surface of the first scraper 51 facing the connecting rod 53 has a spike 511, and the spike 511 is used for scraping off dust adhered to the inner wall of the vent hole 30. When the first scraper 51 moves in the vent hole 30, the spine portion 511 first comes into contact with and collides with dust adhering to the inner wall of the vent hole 30, and the spine portion 511 is designed so that the first scraper 51 can clean the dust adhering to the inner wall of the vent hole 30 more easily.

In one embodiment, the outer surface of the outlet end 21 of the suction pipe 20 has external threads, and the inner wall of the left end of the air vent 30 has internal threads matching the external threads. The dust suction pipe 20 is detachably connected with the shell 10 in a threaded connection mode, so that a worker can conveniently detach the dust suction pipe 20 and clean the dust collection cavity cleaning mechanism 60 together when cleaning the dust collection cavity cleaning mechanism.

In one embodiment, the outlet end 21 has a first alignment block 71 on an outer surface thereof, and the housing 10 has a second alignment block 72 corresponding to the first alignment block 71 on an outer surface thereof at a left end thereof. When the first and second aligning

blocks

71 and 72 are aligned, the inlet end 22 of the suction pipe 20 is just directed toward the grinding wheel 111. The first and

second aligning blocks

71 and 72 allow a worker to more quickly position the suction pipe 20 when installing the suction pipe 20 without repeatedly observing the orientation of the inlet end 22 of the suction pipe 20, thereby improving the installation efficiency of the suction pipe 20.
