Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a vertical toothbrush with a rotatable and replaceable brush head. Background Art
[0002] Both the suggestions of dentists and the common sense of toothbrushing are that vertical brushing is better for teeth than horizontal brushing. The reasons are as follows: vertical brushing can remove foreign matters in tooth gaps and is not easy to damage teeth.
[0003] Currently, the most commonly used toothbrushes are manual toothbrushes, and generally, the brush head and the brush handle are in the same straight line, which does not conform to mechanics and ergonomics. It is easy to cause horizontal brushing when brushing teeth, damaging teeth and not cleaning them thoroughly.
[0004] Some vertical pressing toothbrushes have appeared on the market. Generally, they only set the brush head from vertical to horizontal. Although vertical brushing can be achieved, the positions of the brush head and the brush handle are generally fixed. This kind of toothbrush will cause discomfort in use. The reasons are as follows: it may be easier to exert force when brushing one side of the teeth, but it is not easy to exert force when brushing the other side of the teeth. The force is uneven, and the comfort level of use is not high. Moreover, after a long time, it is easy to cause the defect of incomplete tooth cleaning, and there is room for improvement. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a vertical toothbrush with a rotatable and replaceable brush head, which has a simple structure, is convenient to use, energy-saving and environmentally friendly, and can at least solve one of the above problems.
[0006] According to one aspect of the utility model, there is provided a vertical toothbrush with a rotatable and replaceable brush head, which at least includes:
[0007] A brush handle;
[0008] A brush head, detachably installed on the brush handle;
[0009] One end of the brush handle is provided with a brush handle head rotatably connected to the brush head. The brush handle head is provided with a rotating part and a limiting part. The brush head is provided with a receiving hole rotatably matched with the rotating part and a first limiting protrusion located at both ends of the brush head in the length direction and limitingly matched with the limiting part.
[0010] Thus, the utility model provides a vertical toothbrush with a rotatable and replaceable brush head with a brand-new structure. The brush head and the brush handle of this toothbrush are designed to be detachable, and the brush head or the brush handle can be disassembled and replaced according to needs, realizing repeated use, saving resources, and achieving the technical effect of environmental protection and energy conservation. Secondly, the brush handle head is provided with a rotating part, which can realize the relative rotation of the brush head and the brush handle after assembly, is convenient to use and has a wide application range, and is convenient to achieve comprehensive cleaning. In addition, the brush handle head is provided with a limiting part, which can effectively limit the brush head after changing the direction and is convenient to use.
[0011] In some embodiments, a first opening for limiting and cooperating with the brush head is formed in the brush handle head, and both the rotating part and the limiting part are arranged in the first opening.
[0012] In some embodiments, the rotating part is a rotating shaft, the accommodating hole penetrates through the brush head in the transverse direction, and a second opening is formed on the back surface of the brush head, through which the rotating shaft can enter or disengage from the accommodating hole, and the second opening is communicated with the accommodating hole.
[0013] In some embodiments, a first limiting groove is formed on the inner wall of the accommodating hole, and a second limiting protrusion for limiting and cooperating with the first limiting groove is arranged on the rotating shaft. Thus, the limiting cooperation between the second limiting protrusion and the first limiting groove can make the assembled brush head and the brush handle in a relatively fixed state and prevent swinging during brushing.
[0014] In some embodiments, the rotating part is a pair of oppositely arranged rotating protrusions, and the accommodating hole is formed in the side wall of the brush head and is in limiting cooperation with the rotating protrusions.
[0015] In some embodiments, the vertical toothbrush with a rotatable and replaceable brush head further includes a concave-convex structure, and the brush head and the brush handle head are in limiting cooperation through the concave-convex structure;
[0016] The concave-convex structure includes a third limiting protrusion arranged in the first opening and inside the rotating part and a second limiting groove arranged on the brush head and in limiting cooperation with the third limiting protrusion;
[0017] Alternatively, the concave-convex structure includes a second limiting groove arranged in the first opening and inside the rotating part and a third limiting protrusion arranged on the brush head and in limiting cooperation with the second limiting groove.
[0018] Thus, after the brush handle rotates in place, the limiting of the brush head and the brush handle can be realized through the concave-convex structure, enhancing the stability. Specifically, after the brush handle rotates in place, the limiting cooperation between the second limiting groove and the third limiting protrusion can further limit the brush head and the brush handle, enhancing the stability.
[0019] In some embodiments, both the second limiting groove or the third limiting protrusion arranged on the brush head are a pair, and a pair of second limiting grooves or a pair of third limiting protrusions are respectively arranged on both sides of the accommodating hole.
[0020] In some embodiments, a circular groove is formed on the back surface of the brush head. Thus, the function of scraping the tongue coating can be realized through the circular groove, which is equivalent to a tongue scraper.
[0021] In some embodiments, the toothbrush handle further includes a hand-held portion and a bending portion. The bending portion is disposed between the hand-held portion and the toothbrush head. The angle between the straight line in the length direction of the hand-held portion and the straight line in the length direction of the toothbrush head is greater than 90 degrees and less than 150 degrees. Thus, an obtuse angle greater than 90 degrees is formed between the toothbrush handle and the toothbrush head, and it is very convenient to hold the hand-held portion and brush vertically up and down, and the operation is convenient.
[0022] In some embodiments, bristles are provided on the front surface of the toothbrush head.
[0023] Advantages of the present utility model:
