Description

Technical Field

[0001] This utility model belongs to the field of toothbrush technology, specifically, it relates to a multi-functional toothbrush with an eccentric handle. Background Technology

[0002] Dentists recommend brushing vertically rather than horizontally. Brushing vertically can remove foreign objects between teeth, which is better for teeth and will not damage them.

[0003] Chinese Patent Publication No. CN114224061A discloses a vertical toothbrush, comprising at least: a brush head; a handle detachably mounted to the brush head and engaging with it; a limiting portion is provided on the back of the brush head; a bent portion is provided at one end of the handle, the bent portion being rotatably mounted to and engaging with the limiting portion via a rotating shaft; the limiting portion forming an accommodating space for accommodating and engaging with the bent portion; the bent portion being rotatable along the rotating shaft to both sides of the rotating shaft and fitting against the back of the brush head; the extending direction of the bent portion being consistent with the extending direction of the brush head; and the angle between the straight line containing the length direction of the brush head and the straight line containing the length direction of the handle being an obtuse angle. Although the brush head of this vertical toothbrush is detachable, its position can be adjusted by rotating the brush head using a flipping mechanism.

[0004] However, in actual use, the flipping mechanism of the above-mentioned device requires force to flip, and the brush head is also prone to loosening after prolonged use, which may cause the brush head to injure the gums. After repeated flipping and use, there is friction between the plastic parts, which produces plastic friction debris, which may be accidentally entered into the mouth when brushing. In addition, the structure connecting the brush head and the handle is relatively thick to ensure stability, which may cause a strong foreign body sensation when brushing.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-functional toothbrush with an eccentric handle.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A multi-functional toothbrush with an eccentric handle includes a handle, a neck attached to one end of the handle, a brush head fixedly connected to one end of the neck, and a tongue scraper attached to the bottom of the brush head. The neck includes a first bend and a second bend, the first bend being fixedly connected to one end of the handle, and the second bend being fixedly connected to one end of the brush head. The one end of the handle and the brush head are horizontally offset, and the one end of the handle is eccentrically positioned and corresponds to one end of the brush head.

[0009] Furthermore, the first bend forms an arc angle of 50-150 degrees with the handle, the brush head forms an arc angle of 10-50 degrees with the second bend, the total length of the brush head is 35-45mm, the gap between the handle and the brush head is 4-12mm, and the horizontal offset between the handle and the brush head is 2-10mm.

[0010] Furthermore, the brush head includes a brush plate mounted at one end of the neck and a plurality of bristles mounted on the top of the brush plate, the plurality of bristles being distributed in a rectangular array.

[0011] Furthermore, the brush plate is arc-shaped, and the tips of the multiple bristles form an arc shape corresponding to the brush plate.

[0012] Furthermore, the tongue scraper includes a scraper installed at the bottom of the brush plate and a plurality of protrusions disposed at the bottom of the brush plate, the plurality of protrusions being arranged in a horizontal row.

[0013] Furthermore, the handle is oval-shaped, and a suction cup is provided at one end of the handle.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:

[0015] The neck design allows the brush head to connect to the handle, keeping the handle and brush head as one unit. This makes it easier for users to operate the handle for brushing and reduces the risk of the brush head injuring the gums. The first and second bends allow the brush head to be offset into the oral cavity, with the first and second bends located at the entrance of the oral cavity. This reduces the feeling of the handle being in a foreign object in the oral cavity and increases the cleaning angle and cleaning intensity of the brush head. The eccentric design of the brush head allows the teeth on the left and right sides of the oral cavity to be cleaned separately by rotating the handle.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this embodiment provides a multi-functional toothbrush with an eccentric handle, including a handle 1, a neck 2 installed at one end of the handle 1, a brush head 3 fixedly connected to one end of the neck 2, and a tongue scraper 4 installed at the bottom of the brush head 3; the neck 2 includes a first bend 5 and a second bend 6, the first bend 5 is fixedly connected to one end of the handle 1, the second bend 6 is fixedly connected to one end of the brush head 3, one end of the handle 1 and the brush head 3 are horizontally offset, one end of the handle 1 is eccentrically set and corresponds to one end of the brush head 3.

[0027] One application of this embodiment is as follows: When using the brush, take the handle 1 and insert the brush head 3 into the mouth. At this time, the neck 2 will be located in the mouth. The setting of the first bend 5 and the second bend 6 will cause the brush head 3 to shift and become eccentric, so that the brush head 3 can completely cover the cleaning of the tooth surface and interdental spaces in all directions. The position of the brush head 3 can be adjusted by simply rotating the handle 1. It can brush the teeth horizontally or vertically, realizing multi-angle and multi-directional brushing, and cleaning the residue inside the teeth more thoroughly.

[0028] The neck 2 allows the brush head 3 to connect to the handle 1, keeping the handle 1 and brush head 3 as one unit. This makes it easier for the user to operate the handle 1 to brush their teeth and reduces the risk of the brush head 3 injuring the gums. The first bend 5 and the second bend 6 allow the brush head 3 to be offset into the oral cavity, with the first bend 5 and the second bend 6 located at the entrance of the oral cavity. This reduces the feeling of the handle 1 entering the oral cavity and increases the cleaning angle and cleaning intensity of the brush head 3. The eccentric setting of the brush head 3 allows the teeth on the left and right sides of the oral cavity to be cleaned separately by rotating the handle 1.

[0029] like Figure 2-3As shown, in this embodiment, the first bend 5 forms an arc angle of 50-150 degrees with the handle 1, the brush head 3 forms an arc angle of 10-50 degrees with the second bend 6, the total length of the brush head 3 is 35-45mm, the gap between the handle 1 and the brush head 3 is 4-12mm, and the horizontal offset between the handle 1 and the brush head 3 is 2-10mm. By setting the first bend 5 and the second bend 6, the first bend 5 can be bent at 50-150 degrees, and the second bend 6 can be bent at 10-50 degrees, so that the handle 1 and the brush head 3 are offset and eccentric. The maximum angle formed by the eccentricity between the handle 1 and the brush head 3 is greater than 41 degrees. This makes it easier for the brush head 3 to enter the left teeth and reach the innermost part of the mouth. The first bend 5 and the handle 1 form an arc angle of >90 degrees, which makes it easier for the brush head 3 to enter the right teeth and reach the innermost part of the mouth. The first angle between the brush head 3 and the second bend 6 is 41 degrees. The gap between the brush head 3 and the handle 1 is 4-12mm, which allows 95% of the length of the brush head 3 to enter the left teeth. When entering the left side of the mouth, the toothbrush bristles can completely cover the teeth and brush all the residue between the teeth. The brush head 3 is horizontally offset from the neck by 2-10mm, so that the mouth and neck will not interfere when the brush head enters the mouth, making brushing more convenient.

[0030] like Figure 2-3 As shown, the brush head 3 in this embodiment includes a brush plate 7 mounted on one end of the neck 2 and multiple bristles 8 mounted on the top of the brush plate 7, with the multiple bristles 8 arranged in a rectangular array. The brush plate 7 is arc-shaped, and the tips of the multiple bristles 8 form arc shapes corresponding to the brush plate 7. Through the arrangement of the brush plate 7 and the bristles 8, the arc-shaped arrangement of the brush plate 7 and the multiple bristles 8 can conform to the shape of the teeth, making it easier to reach the gaps and corners when brushing.

[0031] like Figure 3 As shown, the tongue scraper 4 in this embodiment includes a scraper 9 installed at the bottom of the brush plate 7 and multiple protrusions 10 arranged horizontally at the bottom of the brush plate 7. The scraper 9 and protrusions 10 allow for cleaning of the tongue coating while brushing teeth.

[0032] like Figure 4 As shown, the handle 1 in this embodiment is oval-shaped, and a suction cup 11 is provided at one end of the handle 1. The handle 1 is designed in two ways, one of which adds a suction cup 11. The suction cup 11 can be attached to the washbasin, keeping the handle 1 in a vertical position, so that the brush head 3 is located at the top. This allows the handle 1 to be placed and fixed independently. The oval-shaped handle 1 can remain stable when placed flat, preventing the handle 1 from rolling and falling.

[0033] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
