Description

Brush head of electric toothbrush

The technical field is as follows:

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

Background art:

the electric toothbrush is one kind of toothbrush, and the brush head produces high frequency vibration through the fast rotation or vibration of the motor core to decompose toothpaste into fine foam and clean teeth slit, and the vibration of the brush hair can promote the blood circulation in the mouth and massage gum tissue.

Along with the improvement of living standard of people, more and more electric toothbrush articles are applied to daily life of people, and because the electric toothbrush is convenient to use, the cleaning effect is very ideal, and the electric toothbrush is popular with consumers.

When the user is using electric toothbrush, need stretch into the oral cavity with the brush head, the reuse brush hair pastes tight tooth surface and cleans, and the back of brush hair on the tooth that the clean process can touch oral cavity wall or opposite side inevitable, because brush head production high frequency oscillation, and what traditional brush head adopted is hard plastic material, causes the damage of tooth or oral cavity wall easily at brush head back and oral cavity wall or tooth striking. Especially, when the electric toothbrush is used by children, it is difficult to grasp the movement of the brush head, and the teeth of the children are weak and easily damaged when they develop for a long time.

In view of the above, the present inventors propose the following.

The utility model has the following contents:

the utility model aims to overcome the defects of the prior art and provide a brush head of an electric toothbrush.

In order to solve the technical problem, the utility model discloses a following technical scheme: the brush head of the electric toothbrush comprises: the brush hair brush comprises a plastic seat and a plurality of brush hair arranged at one end of the plastic seat, wherein a layer of silica gel sleeve wrapped on the plastic seat is formed on the plastic seat through secondary injection molding, a plurality of bulges are formed on the silica gel sleeve, and the bulges are positioned on one side of the back of the brush hair; the brush installation part on the plastic seat is exposed outside the silica gel sleeve.

Furthermore, in the above technical scheme, a protrusion for positioning the silica gel sleeve is formed on the plastic seat, the protrusion is located in the middle of the protrusion and is lower than the height of the protrusion, and a positioning hole matched and clamped with the protrusion is formed in the middle of the protrusion.

Furthermore, in the above technical solution, the protrusions are distributed along the longitudinal direction of the plastic seat and have different heights.

Furthermore, in the above technical solution, the protrusion surrounds the periphery of the protrusion, and has at least three layers with different heights.

Further, in the above technical solution, the protrusion includes first ridge portions symmetrically disposed on left and right sides of the protrusion, a second ridge portion disposed beside the first ridge portion, a third ridge portion disposed beside the second ridge portion, and a fourth ridge portion disposed at upper and lower ends of the protrusion and located between the first ridge portions, and the positioning hole is located between the first ridge portion and the fourth ridge portion.

Further, in the above technical solution, the first ridge height is: 0.5mm, the second ridge height being: 0.2mm, the third ridge height being: 0.15 mm.

After the technical scheme is adopted, compared with the prior art, the utility model has following beneficial effect: the utility model discloses in through set up a silica gel cover on the plastic seat to be located brush hair back department at the silica gel cover and set up the plural number arch, utilize bulge's difference in height to reduce the brush head and stretch into the oral cavity after, the area of contact of its back and oral cavity wall or tooth, with this area and the probability of reduction brush head contact oral cavity or tooth, thereby play the effect of protection oral cavity inner wall and tooth.

The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific embodiments and accompanying drawings.

Referring to fig. 1 to 8, there is shown a head for an electric toothbrush, comprising: the brush head comprises a plastic seat 1 and a plurality of brush hairs 2 arranged at one end of the plastic seat 1, wherein a layer of silica gel sleeve 3 wrapped on the plastic seat 1 is formed on the plastic seat 1 through secondary injection molding, a plurality of bulges 4 are formed on the silica gel sleeve 3, and the bulges 4 are positioned on one side of the back of the brush hairs; the brush installation part on the plastic seat 1 is exposed out of the silica gel sleeve 3.

The plastic seat 1 is formed with a convex block 5 for positioning the silica gel sleeve 3, the convex block 5 is positioned in the middle of the bulge 4 and is lower than the height of the bulge 4, and a positioning hole 40 matched and clamped with the convex block 5 is formed in the middle of the bulge 4.

In one embodiment, the protrusions 4 are distributed along the longitudinal direction of the plastic seat 1 and have gully shapes with different heights.

The protrusion 4 includes first ridge portions 41 symmetrically disposed on left and right sides of the protrusion 5, second ridge portions 42 disposed on lateral sides of the first ridge portions 41, third ridge portions 43 disposed on lateral sides of the second ridge portions 42, and fourth ridge portions 44 disposed on upper and lower ends of the protrusion 5 and located between the first ridge portions 41, and the positioning hole 40 is located between the first ridge portions 41 and the fourth ridge portions 44.

The first ridge 41 has a height of: 0.5mm, the second ridge 42 height is: 0.2mm, the third ridge 43 height being: 0.15 mm.

In the second embodiment, the protrusion 4 surrounds the protrusion 5 in a racetrack shape, and has at least three layers with different heights.

In conclusion, the silicone sleeve 3 is arranged on the plastic seat 1, the plurality of protrusions 4 are arranged on the back of the bristles 2 of the silicone sleeve 3, and the contact area between the back of the toothbrush head and the oral cavity wall or the teeth after the toothbrush head extends into the oral cavity is reduced by utilizing the height difference of the protrusions 4, so that the area and the probability of the toothbrush head contacting the oral cavity or the teeth are reduced, the damage to the teeth and the oral cavity wall caused by the high-frequency vibration impact of the toothbrush head 2 is reduced, and the effect of protecting the oral cavity inner wall and the teeth is achieved.
