Description

Convenient toothbrush

Technical Field

The invention belongs to the technical field of manual toothbrushes, and particularly relates to a toothbrush convenient for brushing teeth in a reverse hand position.

Background

The toothbrush is a cleaning article, is a handle type brush, is added with toothpaste, can clean teeth by repeatedly brushing the teeth, and is an essential tool for daily nursing of oral cavities. Toothbrushes can be classified into manual toothbrushes and electric toothbrushes. The manual toothbrush is a common toothbrush, is a toothbrush for brushing teeth by driving the toothbrush to do up-and-down reciprocating motion on the teeth by hands, and consists of a toothbrush head and a toothbrush handle, wherein the toothbrush head is provided with bristles. The electric toothbrush is a toothbrush which is driven by electricity to enable a toothbrush head to rotate or vibrate, and the rotating or vibrating toothbrush head rubs with teeth in the process of contacting with the teeth, so that the effect of cleaning the teeth is achieved. The vibration type electric toothbrush is more advanced than the rotation type electric toothbrush, has better protection performance for teeth, and has better effect of cleaning teeth. Electric toothbrushes have a common feature, namely, a relatively loud noise. Advances in toothbrush technology have played an important role in protecting teeth and maintaining oral hygiene.

Although the development of the toothbrush technology has increased to a new level with the development of the electric toothbrush technology, in the actual life of people, most people actually brush teeth by using a manual toothbrush because of the relatively high price of the electric toothbrush or the long-term habit of using the toothbrush.

The manual toothbrush consists of a toothbrush head and a toothbrush handle, and the toothbrush head and the toothbrush handle are connected to form a complete toothbrush. Most of the existing connection modes of the toothbrush head and the toothbrush handle are connected end to end, as shown in figure 1, when the toothbrush is used for brushing teeth, a user can easily extend the toothbrush into the oral cavity to do up and down reciprocating motion when brushing the outer surfaces of the teeth in a handedness position (the other side of the toothbrush hand is held, such as a person who usually uses the right hand, and the left side in the handedness position is shown in figure 2), so that all the teeth can be brushed smoothly. When brushing the outer surface of the teeth in the opposite hand position (the same side of the toothbrush is held by the hand, such as a person who usually holds the right hand, and the right side of the opposite hand, as shown in fig. 3), if the toothbrushing person continues to adopt the posture of holding the toothbrush in the forward hand position, the rearmost teeth in the opposite hand position cannot be brushed due to the blockage of the mouth angle of the toothbrush handle, so the toothbrushing person must turn the toothbrush to extend into the oral cavity in the opposite hand position for brushing teeth, and at the moment, in order to achieve a better brushing effect, the toothbrush still must do up-and-down reciprocating motion. Due to the inconvenience, when brushing the teeth in the opposite hand, a plurality of toothbrushing persons reduce the reciprocating times of the upper and lower toothbrushing or completely abandon the correct toothbrushing mode, and still brush the teeth according to the wrong brushing mode of transversely reciprocating the toothbrush, so that the teeth are not cleaned and protected properly, and even the teeth are damaged by difficult repair because the roots of the teeth are rubbed out by a ditch due to long-term transverse brushing.

Disclosure of Invention

The invention aims to solve the problem that the original toothbrush structure brings inconvenience to a user to brush teeth correctly in a reverse hand position, and provides a reverse hand position convenient toothbrush which is reasonable in structure and facilitates the user to brush teeth in the reverse hand position in a correct posture.

In order to achieve the purpose, the invention adopts the technical scheme that:

the reason why the original toothbrush cannot be used for brushing teeth in the same holding posture as the front hand when used for brushing the outer surface of teeth in the opposite hand is that when people perform actions of grinning teeth for the convenience of brushing teeth to expose the teeth as much as possible, it is impossible to completely expose the teeth because the extent of the outward expansion of the mouth angle is limited, which makes it impossible for people to brush the rearmost teeth in the opposite hand in the same holding posture as the front hand; therefore, when people brush teeth in the reverse hand position, the toothbrush can only be turned around and extend into the oral cavity in the reverse hand position to brush teeth, but the toothbrush is inconvenient. The scheme for solving the problems is that the structure of the toothbrush is improved, and the V-shaped groove is arranged in the toothbrush structure, so that when people brush teeth in a reverse hand position, particularly brush the rearmost teeth which can not pass through grinning teeth, the toothbrush can still extend into the oral cavity of the reverse hand position when the holding posture which is the same as the positive hand position is adopted, the phenomenon that the toothbrush handle is blocked by a mouth angle is eliminated, and the purpose of brushing the outer surfaces of the teeth in the reverse hand position, particularly the rearmost teeth which can not pass through grinning teeth by adopting the most convenient toothbrush holding posture and the correct brushing method is achieved. The specific scheme is as follows:

the toothbrush comprises a toothbrush head, a toothbrush handle and a toothbrush head, wherein the head of the toothbrush head is connected with the head of the toothbrush handle, a V-shaped groove with an opening angle of about 8-12 degrees is formed between the back of the toothbrush head and the front end of the toothbrush handle (the part with the length L of 35-45 mm from the head of the toothbrush handle to the back), the opening direction of the V-shaped groove is an opening towards the tail of the toothbrush handle, the depth of the V-shaped groove is about 20-30mm, the direction of toothbrush bristles faces outwards, and the tooth brushing surface of the toothbrush bristles is parallel to the front end of the toothbrush handle.

The invention has the following effects:

the invention improves the structure of the manual toothbrush, so that a user can conveniently brush the outer surfaces of all the teeth (especially the teeth at the back) at the opposite hand position by adopting the most convenient toothbrush holding posture and a correct brushing method when brushing teeth, and the user only adopts one toothbrush holding posture (also the most smooth posture) all the time when brushing teeth, namely, the toothbrush does not need to be turned around at the opposite hand position during the process of brushing teeth and is forced to adopt the awkward posture, thereby greatly improving the convenience of manual tooth brushing. Therefore, the problem that a plurality of toothbrushing persons brush the teeth in the opposite hand by adopting a correct tooth brushing method (the toothbrush conducts up-and-down reciprocating motion to brush the teeth) due to inconvenience in brushing the teeth in the opposite hand is avoided, the reciprocating times of up-and-down tooth brushing are reduced or the correct tooth brushing mode is completely abandoned, the teeth are brushed by the wrong scrubbing mode of enabling the toothbrush to conduct transverse reciprocating motion, the teeth are finally not cleaned and protected, and the problem that the teeth are damaged by difficult restoration due to the fact that the roots of the teeth are rubbed out of a ditch when the teeth are scrubbed transversely for a long time is further avoided.

Detailed Description

The invention is further illustrated by the following example.

The reverse-hand convenient toothbrush shown in figures 4-9 comprises a toothbrush head 1 and a toothbrush handle 2, wherein the toothbrush head 1 is provided with bristles 3. The toothbrush head 4 of the toothbrush head 1 is connected with the handle head 7 of the toothbrush handle, a V-shaped groove 10 with an opening angle of about 8-12 degrees is formed between the toothbrush head back 5 of the toothbrush head 1 and the front handle end 8 of the toothbrush handle 2 (a part with a backward length L of 35-45 mm from the head 7 of the toothbrush handle 2), the V-shaped groove is arranged so that the tooth brushing posture is not required to be switched when the toothbrush is in an opposite hand position, the toothbrush can be smoothly brushed by embedding a mouth angle into the V-shaped groove in an original posture, the opening direction of the V-shaped groove 10 is an opening towards the tail 9 of the toothbrush handle 2, the depth of the V-shaped groove 10 is about 20-30mm, the toothbrush bristles 3 face outwards, and the tooth brushing surface 6 of the toothbrush bristles 3 is parallel to the front handle end 8 of the toothbrush handle 2. The user only adopts a toothbrush holding posture (also the most smooth posture) all the time when brushing teeth, namely the toothbrush does not need to be turned around when in the reverse hand position in the process of brushing teeth, and the user is forced to adopt the awkward posture, thereby greatly improving the convenience of manual tooth brushing. Therefore, the inconvenience of brushing teeth by adopting a correct tooth brushing method (enabling the toothbrush to do up-and-down reciprocating motion to brush teeth) in the opposite hand position is avoided, so that a plurality of toothbrushing persons can reduce the reciprocating times of up-and-down tooth brushing or completely abandon the correct tooth brushing method when brushing the teeth in the opposite hand position, and can brush the teeth by adopting the wrong rubbing mode which enables the toothbrush to do transverse reciprocating motion, and finally the teeth are not cleaned and protected.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the invention, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the invention.
