Abstract

The utility model discloses a spiral telescopic health-care toothbrush which is composed of a short handle brush head, an inner sleeve with a subbase, an outer sleeve and a casing cover, wherein a linear slideway is arranged on the inner sleeve, and a spiral groove is arranged in the outer sleeve; a cylinder body of the handle end of the short handle brush head is provided with a pair of small cylinder-shaped bulges which pass through the linear slideway of the inner sleeve and extend into the spiral groove of the outer sleeve, and the relative rotation of the inner and the outer sleeves can make the short handle brush head telescope in axial direction. The utility model has the advantages of convenient use, sealed and dustproof property and convenient carrying and storage.

Description

Tooth brush for health protection

The utility model belongs to the brush based article, is specifically related to a kind of tooth brush for health protection.

Old-fashioned toothbrush all is that bristle is formed with long brush holder, and the toothbrush overall length is placed and carry very inconvenient about 15-20cm.Toothbrush is the necessity for life that a kind of needs keep clean, and the bristle dust that easily falls that is exposed for a long time is harmful to health.People had invented the toothbrush of tape drum gradually afterwards, and the two-section type toothbrush comprises hinged and is threaded, or the like.Though these toothbrushes have overcome the shortcoming that stock, bristle expose, but have increased use loaded down with trivial details, being difficult for widely, people accept.

The purpose of this utility model provides that a kind of length is scalable, bristle can seal and toothbrush easy to use.

The solution that the utility model adopts is: tooth brush for health protection is made of inner sleeve, outer sleeve and the upper shield of short handle brush, band base.The pommel portion of short handle brush is a cylinder, and the small cylindrical projection of a pair of symmetry is arranged on the cylinder outer wall; Inner sleeve is enclosed within on the cylinder of short handle brush, and inner sleeve one end is connected with base, the axial linear ramp of a pair of symmetry is arranged, divulging on inner sleeve; Outer sleeve is enclosed within on the inner sleeve, the spiral channel that two symmetries are arranged on the madial wall of outer sleeve, the linear ramp that small cylindrical projection on the short handle brush cylinder is passed inner sleeve reaches in the spiral channel of outer sleeve, when outer sleeve and inner sleeve relatively rotate, the short handle brush then relatively inner and outer sleeves axially move.Upper shield is the cylinder of end sealing, and its internal diameter matches with the outer sleeve external diameter.When toothbrush uses, pull up upper shield, hold base rotating jacket tube, bristle is stretched out, can brush teeth easily; With complete cycle, cover upper shield, make bristle be in the complete closed state, it is short to have reached entire length, the dustproof effect that keeps clean.

The utlity model has following advantage:

1, owing to adopted stretching structure, brush holder has sufficient length when stretching out, and brushes teeth conveniently; Overall length is short during indentation, is easy to carry about with one and deposits.

When 2, not brushing teeth, brush and short handle indentation inner sleeve thereof are detained with upper shield again, reach complete closed, can prevent dust, keep clean.

3, its spiral stretching structure uses very conveniently, and toothbrush flexible moment can finish, and makes the people unconsciously loaded down with trivial details, is easy to accept.

Further specify structure of the present utility model below in conjunction with drawings and embodiments.

The pommel portion of short handle brush 3 is designed to cylinder, and the outer wall of cylinder is provided with the small cylindrical projection perpendicular to two symmetries of cylinder axis; Inner sleeve 5 one ends and base 4 are connected as one, have the axial linear ramp that two symmetries are divulged on the barrel of inner sleeve 5, wherein the straight line slideway reaches the opening part of the inner sleeve other end always from base, another linear ramp reaches opening part near the inner sleeve other end from base always, at inner sleeve near base position and the other end near opening part, respectively have a circumferential short slideway that communicates with linear ramp, the opening direction of two circumferentially short slideways is opposite.The circumferential short slideway of inner sleeve 5 openends is last restriction point 6, the position when being used for fixing short handle brush 3 and stretching out, when preventing to brush teeth about string moving; The circumferential short slideway of inner sleeve base end is following restriction point 7, makes fixed-site behind the short handle brush indentation inner sleeve.All there is convex shoulder at the two ends of inner sleeve 5 (openend and base end) along circumferential direction, and outer sleeve about 1 strings that prevent to overlap in the above are moving.The internal diameter of outer sleeve 1 matches with the external diameter of inner sleeve 5, the inwall of outer sleeve has two symmetrical spiral channels, article two, the inside spin conduit is slotted from top, an end of outer sleeve, reach near outer sleeve the other end always, parameter ratios such as the number of leads of these two spiral channels, pitch, helical pitch, big path, tooth form should be able to satisfy when inner sleeve is relative with outer sleeve to be rotated, the short handle brush can be in inner sleeve move left and right.The rotation direction of outer sleeve spiral inner wall conduit should adapt with the opening direction of the circumferentially short slideway in inner sleeve two ends.Outer sleeve 1 is not opened an end inboard of spiral channel and is opened a circumferential recessed shoulder, and this recessed shoulder and inner sleeve 5 openend convex shoulder sizes are complementary, and prevents that outer sleeve and inner sleeve from going here and there to axial, only limits inner and outer sleeves to relatively rotate at same axis.Short handle brush 3, inner sleeve 5, outer sleeve 1 are nested together successively, and upper shield 2 is enclosed within on the outer sleeve 5.The linear ramp that small cylindrical projection on the short handle brush 3 pommel cylinders is passed inner sleeve 5 extend in the inside spin conduit of outer sleeve 1, when inner and outer sleeves relatively rotates, small cylindrical projection on short handle brush 3 cylinders is slided in the spiral channel of inner sleeve 5 linear ramps and outer sleeve 1, guiding short handle brush in inner sleeve along the sleeve axis move left and right.
