Technical Field

The invention relates to the field of dental disease treatment and prevention, in particular to a dental sand blasting bottle.

Background

The existing sand blasting cleaning and treating equipment utilizes compressed gas (usually air) to lift dental sand blasting powder (the main component is usually sodium bicarbonate, glycine or erythritol) to be sprayed onto the surface of a tooth and is converged with a liquid medium (usually water) sprayed together to play a role in cleaning the surface of the tooth, dental plaque, soft scale, early dental calculus, smoke stain, tea stain and the like on the surface of the upper gingival tooth and the lower gingival tooth can be specifically removed, periodontal disease can be effectively prevented, the health of the tooth is maintained, in order to realize a continuous sand blasting treatment effect, the used sand blasting equipment is required to be provided with a sand blasting bottle, the traditional sand blasting bottle is influenced by the structure in the using process, the sand powder stored in the traditional sand blasting bottle is easy to agglomerate, and the inlet of a sand outlet pipe is not subjected to flow guide treatment, so that the pipeline is blocked and the use is influenced.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a dental sandblasting bottle, so as to overcome the defects in the prior art.

The technical scheme for solving the technical problems is as follows: the utility model provides a dentistry sandblast bottle, includes bottle, bottle lid, base, pipe and play sand pipe, and bottle lid and base link to each other with the upper and lower both ends of bottle respectively, and the pipe is inlayed interior knot with the base and is connected, is equipped with on the base in order to go out the sand pipe with bottle inner chamber and external intercommunication, and the inner wall of base is circular-arcly, and the base is equipped with the air inlet, has the arc wall on the lower terminal surface of bottle lid, is equipped with a plurality ofly by the outside guiding gutter that extends in arc wall center in the arc.

The invention has the beneficial effects that: the inner wall of the base is arc-shaped, so that the sand powder in the bottle is prevented from forming overstock at the bottom; the lower terminal surface of bottle lid has the arc wall, is equipped with a plurality ofly in the arc wall by the outside guiding gutter that extends in arc wall center, and a plurality of guiding gutters that establish in the arc wall form chrysanthemum flower column structure with the arc wall jointly, and the sand powder is blown up the back from the bottom, beats the bottle lid on, is fully broken up by the chrysanthemum flower column structure of its lower terminal surface, avoids forming the caking, lets the sand powder fully disperse the back, in the removal of whole sandblast pipeline, can not plug up the pipeline.

On the basis of the technical scheme, the invention can be further improved as follows.

Furthermore, one end of the diversion trench, which is far away from the axis of the bottle cap, extends to intersect with the edge of the arc-shaped trench.

Furthermore, the distance between the guide grooves is smaller than the inner diameter of the sand outlet pipe, and the tangent extension line of the guide groove far away from the outer edge point of the central axis falls into the pipe orifice of the sand outlet pipe.

The beneficial effects of the two steps are as follows: after the sand powder is fully dispersed, the sand powder can be effectively conveyed into the sand outlet pipe through the guide of the guide groove.

Furthermore, the included angle between the tangent line of one end of the diversion trench far away from the axial lead of the bottle cap and the axial lead of the bottle cap is 30-60 degrees.

Furthermore, the included angle between the tangent line of one end of the diversion trench far away from the axial lead of the bottle cap and the axial lead of the bottle cap is 45 degrees.

The beneficial effects of the two steps are as follows: the sand powder dispersion and flow guide effect is better.

Further, the width of the diversion trench is linearly increased outwards from the axial lead of the bottle cap.

Adopt above-mentioned further beneficial effect to do: is beneficial to the dispersion of the sand powder.

Furthermore, the inner wall of the base is in a gradually contracted trumpet shape from top to bottom in the horizontal direction.

Adopt above-mentioned further beneficial effect to do: avoid the sand powder in the bottle to form the backlog in the bottom and be favorable to the sand powder to fall back when working and carry out the circulation of kicking up again.

Further, the bottle cap is in threaded connection with the bottle body.

Adopt above-mentioned further beneficial effect to do: the disassembly and the assembly are convenient.

Further, a sealing ring a is arranged between the outer circumference of the bottle cap and the inner wall of the bottle body.

Adopt above-mentioned further beneficial effect to do: the sealing performance between the bottle cap and the bottle body is improved.

Further, the base is in threaded connection with the bottle body.

Adopt above-mentioned further beneficial effect to do: the disassembly and the assembly are convenient.

Further, a sealing ring b is arranged between the outer circumference of the base and the inner wall of the bottle body.

Adopt above-mentioned further beneficial effect to do: the sealing performance between the base and the bottle body is improved.

Further, the air inlet is positioned at the center of the bottom of the base; a guide pipe is arranged on the base and is opposite to the air inlet.
