Abstract
The utility model discloses a chalk butt dust collection device, which is characterized by comprising an outer conical clamping plate (1) and an inner conical fastening ring (2). The inner conical fastening ring (2) is arranged on the outside of the outer conical clamping plate (1), the front end of the outer conical clamping plate (1) is provided with an opening (3) while the rear end of the outer conical clamping plate (1) is provided with an external thread (4), the external thread (4) is screwed with an internal thread at the front end of a dust collector (5), the front end of a handle (6) is connected with a casing (5a) of the dust collector (5), and a cavity (7) is arranged in the handle (6). Compared with the existing method in use, the chalk butt dust collection device has the advantages of convenience in use, lowered waste and higher utilization rate of chalks, and is capable of collecting dust, avoiding environmental pollution and benefitting physical health of teachers.
Description
Technical field
The utility model relates to a kind of chalk fixture head, specifically a kind of joint chalk dust exhaust apparatus.
Background technology
At present, units such as school, office the teaching and training process in, the chalk that the teacher uses on blackboard; Write at need when seizing on both sides by the arms with hand, just throw away it, the teacher who has feels to throw away unfortunately; Just pinch the chalk head with finger and continue to use, the former throws away unfortunately, causes waste; The latter also writes because of the teacher firmly pinches the chalk head, uses very inconvenience, and the time has been grown, finger pain; Chalk foam when other writes, contaminated environment, the harm teacher's is healthy.
Summary of the invention
It is a kind of easy to use that the purpose of the utility model is to provide, and cuts the waste, and improves the chalk utilization rate, and the ability dust suction is avoided environmental pollution, the joint chalk dust exhaust apparatus that favourable teacher is healthy.
For reaching above purpose, the technical scheme that the utility model is taked is: this joint chalk dust exhaust apparatus is characterized in that it is made up of Outer Taper grip block, inner cone tight loop; The inner cone tight loop is established in the outside of Outer Taper grip block, and front end is established opening, and external screw thread is established in the rear end; External screw thread is screwed in the internal thread of dust exhaust apparatus front end; The front end of handle is connected with the housing of dust exhaust apparatus, in establish cavity, contain the chalk foam that dust suction is come in the cavity.The utility model is also implemented through following measure: described dust exhaust apparatus; Constitute by housing, micromachine, battery case, battery, cell switch, dust-absorbing fan, air suction opening, establish micromachine in the housing, the peripheral hardware battery case; Establish battery in the battery case; The peripheral hardware cell switch, miniature electrical machinery axle connects dust-absorbing fan, and air suction opening is located at the front end of housing.When using the utility model,, the chalk head is packed in the Outer Taper grip block earlier with moving behind the inner cone tight loop; Before push away the inner cone tight loop then; Reinforce the chalk head, the teacher opens cell switch when writing; The micromachine rotation drives dust-absorbing fan work, and the chalk foam gets in the cavity of handle through air suction opening.
The beneficial effect of the utility model is: compares with present method for using, not only has easy to usely, cut the waste, improve the advantage of chalk utilization rate, can dust suction but also have, and avoid environmental pollution, the function that favourable teacher is healthy.
