Description

Replacement head for electric toothbrush

Technical Field

The utility model relates to the technical field of electric toothbrushes, in particular to a replacement head for an electric toothbrush.

Background Art

With the development of science and technology and the improvement of people's living standards, electric toothbrushes have been increasingly widely used by people. Electric toothbrushes are better at cleaning teeth than traditional toothbrushes and are more convenient to use. Current electric toothbrushes include replacement heads and handheld handles. The replacement heads are plugged into the handheld handles. The bristles on the replacement heads will wear out and breed bacteria after being used for a period of time, so the replacement heads need to be replaced regularly. During the use of current electric toothbrush replacement heads, the handle part is prone to collision with the teeth, and the cleaning effect of the bristles is not good enough, which is prone to more friction with the gums, causing gum damage.

Utility Model Content

The technical problem to be solved by the utility model is to overcome the above technical defects and provide an electric toothbrush replacement head, which has good cleaning effect, can reduce the collision between the brush handle and the teeth, and can reduce the damage to the gums.

In order to solve the above technical problems, the technical solution provided by the utility model is: an electric toothbrush replacement head, including a brush handle, a tail plug is provided at one end of the brush handle, and a hair transplanting piece is inserted at the other end, and a large hair bundle is provided on the hair transplanting piece, and at least one brush wire is provided on the hair transplanting piece around the large hair bundle, and the top surface of the brush wire is lower on the side relative to the large hair bundle than on the side close to the large hair bundle, and the upper end of the brush wire is inclined in the direction relative to the large hair bundle, and the brush wire close to the brush handle is 1.5mm away from the brush handle.

Compared with the prior art, the utility model has the following advantages: during use, the brush wires at both ends of the implanted bristle sheet can effectively clean the posterior alveolar grooves and tooth gaps; the inner side of the top surface of the brush wires is higher than the outer side, and the brush wires are inclined outwards; the raised brush wires on the inner side can clean the gum gaps; the brush wires at both ends are inclined outwards as a whole bundle, which can increase the cleaning area of the brush wires, thereby improving the efficiency of cleaning teeth; the brush wires with lower outer height can reduce the contact between the brush wires and the gums, thereby reducing the occurrence of gum friction damage; the distance between the brush wires and the brush handle is close, which can reduce the situation where the brush handle hits the teeth.

As an improvement, the brush filaments are fixed on the hair transplanting sheet by hot melting through hair transplanting equipment.

As an improvement, the hair-planting sheet is ultrasonically fixed to the brush handle by means of an ultrasonic wave device.

As an improvement, the tail plug is installed at one end of the brush handle through an auxiliary device.

As an improvement, the top surface of the brush filament is crescent-shaped.

As an improvement, the material of the brush filament is nylon, the material of the hair-planting sheet is plastic and ABS, the material of the brush handle is plastic and ABS, and the material of the tail plug is plastic and POM.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

In conjunction with Figures 1, 2 and 3, an electric toothbrush replacement head includes a brush handle 3, one end of the brush handle 3 is provided with a tail plug 4, and the other end is plugged with a hair transplanting sheet 2, the tail plug 4 is installed at one end of the brush handle 3 through an auxiliary device, the hair transplanting sheet 2 is provided with a large hair bundle 5, and the hair transplanting sheet 2 is provided with at least one brush filament 1 around the large hair bundle 5, the brush filament 1 is fixed to the hair transplanting sheet 2 by hot melting through a hair transplanting device, and the hair transplanting sheet 2 is ultrasonically fixed to the brush handle 3 by an ultrasonic wave device.

In conjunction with Figures 1, 2 and 3, the top surface of the brush filament 1 is crescent-shaped, and the side of the top surface of the brush filament 1 relative to the large hair bundle 5 is lower than the side close to the large hair bundle 5. The raised brush filament 1 on the inner side can clean the gum gap, and the height of the brush filament 1 on the outer side is low, which can reduce the contact with the gums, thereby avoiding friction between the brush filament 1 and the gums and causing damage to the gums. The brush filaments 1 at both ends of the hair-planting sheet 2 are higher than the brush filaments 1 in the middle, and the brush filaments 1 at both ends of the hair-planting sheet 2 are inclined at an angle of 5°. The brush filament 1 at the end can effectively clean the posterior alveolar grooves and tooth gaps. The upper end of the brush filament 1 is inclined toward the direction of the relatively large hair bundle 5, which can increase the cleaning area of the brush filament 1 and improve the efficiency of cleaning teeth. The brush filament 1 close to the brush handle 3 is 1.5mm away from the brush handle 3, which can reduce the collision between the brush handle 3 and the teeth. The material of the brush filament 1 is nylon, the material of the hair implantation sheet 2 is plastic and ABS, the material of the brush handle 3 is plastic and ABS, and the material of the tail plug 4 is plastic and POM.

The utility model is specifically implemented and used, and the brush wires at both ends of the implanted bristle sheet can effectively clean the posterior alveoli and tooth gaps, and the large bristle bundle located in the middle integrates a larger number of brush wires, which can increase the area of teeth polishing, the inner side of the top surface of the brush wire is higher than the outer side, and the upper end of the brush wire is inclined in the direction of the large bristle bundle, and the height of the inner top surface is higher, which can achieve the effect of the brush wire cleaning the gum gaps, and the brush wires at both ends are inclined outward as a whole bundle, which can increase the area of teeth cleaned by the brush wire, thereby improving the efficiency of teeth cleaning during use, and the brush wires with lower outer top surface height can reduce the contact between the brush wire and the gums, avoid the gums being rubbed by the brush wire, thereby reducing the damage to the gums, and because the distance between the brush wire and the brush handle is close, when the brush wire contacts the teeth during brushing, the distance between the brush handle and the teeth can be avoided, which can reduce the situation where the brush handle hits the teeth.
