Description

Technical Field

[0001] The utility model relates to the technical field of brush products, in particular to an easy-to-dry toothbrush head and a portable toothbrush. Background Art

[0002] For personal hygiene reasons, people often carry their own toothbrushes when traveling on business. Various portable toothbrushes currently available on the market are divided into two basic structures. One is a combination of a toothbrush and a toothbrush box, such as a structure disclosed in Chinese patent document CN207100872U, in which the toothbrush is hinged in the toothbrush box or retracted in the toothbrush box. The toothbrush head is folded or pushed out before use, and the toothbrush box serves as part of the brush handle. The other is a combination of a brush handle with toothpaste and a brush head with a head cover, such as a structure disclosed in Chinese patent document CN219982365U. The main shortcomings of the above two structures are that the bristles are trapped in a confined space, and the moisture in the bristles is not easy to evaporate after brushing, which is easy to breed bacteria.

[0003] Secondly, for teeth wearing dental braces, food residues are more likely to remain on them, and the frequency of brushing will increase, so it is necessary to carry a toothbrush with you. Chinese patent document CN202476816U discloses a toothbrush that is convenient for cleaning braces, and its bristles are in a V-shaped groove suitable for cleaning braces, and the braces can be better cleaned through its inclined working surface. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an easy-to-dry toothbrush head and a portable toothbrush, which are not only conducive to the drying and cleaning of the bristles, but also suitable for cleaning teeth wearing dental braces.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] Easy-dry toothbrush head, including

[0007] a brush head base, on which bristles are arranged;

[0008] A brush head handle is fixed to one end of the brush head base;

[0009] The brush head base is provided with a push plate groove along its length direction, the push plate groove extends to the brush head handle, and a movable push plate that can move along the push plate groove is arranged on the push plate groove, so that the movable push plate can change position between the brush head base and the brush head handle;

[0010] The brush head base and the movable push plate are both provided with bristles; when the movable push plate moves to the brush head handle, the brush head base has bristles only on the left and right sides; when the movable push plate moves to the brush head base, the bristles on the movable push plate fill the gaps between the bristles on both sides of the brush head base.

[0011] The invention concept of the present invention is: the bristles on the toothbrush head are divided into two parts, one part is fixed to the base of the brush head and cannot move, and the other part is fixed to the movable push plate and can move relative to the base of the brush head. When the bristles on the movable push plate are separated from the bristles on the base of the brush head, the water remaining on the bristles is easy to evaporate. Moreover, it is also convenient to clean the bottom of the bristles.

[0012] On the other hand, when it is necessary to brush teeth wearing dental braces, the movable push plate can be moved to the handle of the brush head, and the bristles on both sides of the base of the brush head can cross the two sides of the dental braces, so as to facilitate horizontal cleaning of the teeth on both sides of the dental braces. When it is necessary to clean the gap between the teeth and the dental braces, the bristles on one side of the base of the brush head can also relatively conveniently clean the gap horizontally or vertically.

[0013] As a preferred solution, the transverse width of the bristles on the movable push plate is 1 / 4-1 / 3 of the distance between the two outer edges of the bristles on the base of the brush head.

[0014] As a preferred solution, a hand-pushing portion is provided at one end of the movable push plate to facilitate moving the movable push plate.

[0015] As a preferred solution, the brush head handle has a hinged end for connecting with other components.

[0016] As a further preferred solution, the push plate groove is provided with positioning points at the brush head base and the brush head handle, which are used to position the movable push plate at the brush head base or the brush head handle, thereby reducing the probability of the movable push plate sliding arbitrarily in the push plate groove.

[0017] The portable toothbrush described in the present application comprises the above-mentioned easy-drying toothbrush head and a toothbrush box, wherein the easy-drying toothbrush head is located inside the toothbrush box.

[0018] As a preferred solution, the toothbrush box comprises a box body base and a box body cover which are hinged to each other, and the brush head handle of the easy-drying toothbrush head is hinged to the box body base.

[0019] As a further preferred solution, a bayonet is provided on the top of the base of the box body, and when the handle of the brush head is turned outward so that the base of the brush head is outside the toothbrush box, the handle of the brush head abuts against the bayonet. The bayonet also serves as a vent, and when the easy-drying toothbrush head is inside the toothbrush box, the bayonet serves as ventilation.

[0020] In summary, the utility model changes the cross-section of the bristle portion at the base of the brush head between a concave shape and a square shape by moving the movable push plate carrying the bristles along the push plate groove. When in the concave shape, it is beneficial to the drying and cleaning of the bristles, and is also convenient for cleaning teeth wearing dental braces. When in the square shape, it is in the traditional bristle state. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims of this application.

[0028] Example 1

[0029] like Figure 1 As shown, the easy-drying toothbrush head described in the utility model includes two major components: a brush head base 10 and a brush head handle 30. One end of the brush head handle 30 is fixed to the brush head base 10, and the other end of the brush head handle 30 is a hinged end 31. The brush head base 10 is provided with a push plate groove 40 along its length. The push plate groove 40 extends to the brush head handle 30, and a movable push plate 50 that can move along the push plate groove 40 is arranged on the push plate groove 40, so that the movable push plate 50 can change its position between the brush head base 10 and the brush head handle 30. A hand push portion 51 is provided at one end of the movable push plate 50 to facilitate movement. Figure 2As shown, the cross section of the push plate groove 40 is convex-shaped to facilitate clamping the movable push plate 50, and the cross section of the movable push plate 50 is also convex-shaped to facilitate clamping with the push plate groove 40. The push plate groove 40 is provided with positioning points 41 at the brush head base 10 and the brush head handle 30, which are used to position the movable push plate 50 at the brush head base 10 or the brush head handle 30. Among them, the positioning points 41 are semicircular convex points, which can increase the clamping force of the two sides of the push plate groove 40 on the movable push plate 50, and prevent the movable push plate 50 from moving randomly in the push plate groove 40.

[0030] like Figure 1 As shown, bristles 20 are arranged on both the brush head base 10 and the movable push plate 50. When the movable push plate 50 moves to the brush head handle 30, the brush head base 10 only has bristles 20 on the left and right sides; when the movable push plate 50 moves to the brush head base 10, the bristles 20 on the movable push plate 50 fill the gap between the bristles 20 on both sides of the brush head base 10. The transverse width d1 of the bristles 20 on the movable push plate 50 is 1 / 4-1 / 3 of the distance d2 between the two outer edges of the bristles on the brush head base 10.

[0031] When it is necessary to brush teeth 70 wearing dental braces 80, the movable push plate 50 can be moved to the brush head handle 30, and the bristles 20 on both sides of the brush head base 30 can cross the dental braces 80 on the surface of the teeth 70, so as to facilitate horizontal cleaning of the teeth 70 on the upper and lower sides of the dental braces 80. When it is necessary to clean the gap between the teeth 70 and the dental braces 80, the bristles 20 on one side of the brush head base 30 can be used sideways, so as to facilitate horizontal or vertical cleaning of the gap.

[0032] When it is necessary to brush the teeth 70 wearing dental braces 80, the movable push plate 50 can be first moved to the brush head base 10, and toothpaste is squeezed on the tooth surface and rubbed several times. When the foam increases, the movable push plate 50 is moved to the brush head handle 30, so that the cross-section of the bristles at the brush head base 10 is concave.

[0033] Example 2

[0034] like Figure 4 As shown, the portable toothbrush includes two major components: an easy-drying toothbrush head and a toothbrush box 60. The toothbrush box 60 includes a box body base 61 and a box body cover 62 which are hinged to each other. The handle 30 of the easy-drying toothbrush head is hinged to the box body base 61. When the easy-drying toothbrush head is stored in the toothbrush box 60, the movable push plate 50 is fixed to the handle 30, which is conducive to the evaporation of water on the bristles.

[0035] like Figure 5 As shown, a slot 63 is provided at the top of the box body base 61. When the brush head handle 30 is turned outward to make the brush head base 10 outside the toothbrush box 60, the brush head handle 30 abuts against the slot 63. The figure shows the state when the movable push plate 50 is fixed to the brush head base 10.
