Technical Field

[0001] The utility model relates to the technical field of electric toothbrush heads, in particular to a fully rubber-encapsulated electric toothbrush head. Background Art

[0002] At present, electric toothbrushes are very popular. Many users choose electric toothbrushes to protect their oral health. During use, the electric toothbrush is composed of an electric toothbrush handle and an electric toothbrush head. The electric toothbrush handle is equipped with a vibration motor that drives the electric toothbrush head to vibrate. The electric toothbrush head is responsible for brushing the teeth in the mouth. The electric toothbrush is composed of a brush handle and an end head, and the end head is located at one end of the brush handle.

[0003] At present, electric toothbrush heads are produced by injection molding the primary and secondary coatings of a plastic machine at the same time. However, the positioning effect of the end of the brush handle is poor during the secondary coating injection molding, which can easily cause the brush handle to be displaced by the injection pressure during the secondary coating injection molding. In addition, the end of the brush handle has poor anti-bending effect during use. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the end of the brush handle of the current electric toothbrush head has a poor positioning effect during the secondary encapsulation injection molding, which easily causes the brush handle to be displaced by the injection pressure during the secondary encapsulation injection molding, and the end has a poor anti-bending effect during use.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a fully rubber-coated electric toothbrush head, including a brush handle and an end head located at one end of the brush handle, the end head is provided with a boss, the boss is provided with a hair-planting sheet, the boss is provided with a soft rubber coating around the hair-planting sheet, the hair-planting sheet is provided with at least one bristle, the boss protrudes to the inner side of the back side of the hair-planting sheet, the boss is at a 90° angle, the hair-planting sheet is provided with a raised portion, the length of the raised portion is greater than the length of the hair-planting sheet, and the soft rubber coating is adhered to the raised portion.

[0008] As an improvement, a tail plug is inserted into the brush handle, and the tail plug is inserted into the brush handle through an auxiliary hydraulic device.

[0009] As an improvement, the tail plug is made of POM material.

[0010] As an improvement, the bristles are made of nylon, and the bristle implanting sheet and the brush handle are both made of PP.

[0011] As an improvement, the soft rubber coating is made of TPE material.

[0012] As an improvement, the size of the brush handle and the boss is the same as the size of the hair-planting sheet, and the soft rubber coating can be designed according to the size of the hair-planting sheet, and the size requirement of the end head can be ignored.

[0013] (III) Beneficial effects

[0014] The advantages of the utility model compared with the prior art are:

[0015] 1. The boss protrudes to the inner side of the back of the planting piece, so that the end head can play a positioning effect during the secondary encapsulation injection molding, which can effectively improve the phenomenon that the brush handle is displaced by the injection pressure during the secondary encapsulation injection molding;

[0016] 2. The contact part between the brush handle and the hair-planting sheet is in a fitted state, and the boss is at a 90° angle. The boss corner can effectively prevent the soft glue from entering the inner side of the hair-planting sheet during the secondary encapsulation injection molding, causing adverse effects such as damage to the brush wire;

[0017] 3. The raised part is located at the bending stress point of the brush handle, which can effectively disperse the bending stress of the end, making the end less likely to break and enhancing the bending resistance of the end;

[0018] 4. The raised part can increase the adhesion area between the rubber-coated soft glue and the wool-planting sheet and strengthen the adhesion firmness, so that the rubber-coated soft glue and the wool-planting sheet are not easy to crack when the adhesion is pulled by force.
