An embodiment of the first aspect of the present application provides a toothbrush head, as shown in fig. 1, which includes a head body 100, and it is understood that the head body 100 is made of hard materials such as plastic, and has high hardness. The brush head body 100 includes a bristle holder Mao Ji, and bristles 130 are disposed on the bristle holder 110. During the brushing process, at least part of the bristle base 110 extends into the oral cavity of the human body, so that the bristles 130 are driven to vibrate by the vibration of the brush head body to clean the teeth.

In order to avoid discomfort caused by direct contact between teeth and the hard implant Mao Ji, the toothbrush head according to the embodiment of the application further includes a shock absorbing member 200, as shown in fig. 1 to 5, wherein the shock absorbing member 200 is wrapped around the toothbrush head, and more specifically, the shock absorbing member 200 is wrapped around at least the bristle planting base 110. As shown in fig. 4 and 5, the shock absorbing member 200 has a thin-shell structure, and defines an accommodating cavity 210 therein, and when the shock absorbing member 200 is coated on the hair-planting base 110, the hair-planting base 110 is positioned in the accommodating cavity 210. It can be appreciated that the shock absorbing member 200 is provided with a first opening 220 communicating with the accommodating chamber 210, and the first opening 220 is used for exposing the bristles 130.

As shown in fig. 2, for convenience of the following description, a surface of the bristle bearing base 110 to which bristles 130 are attached is designated as a first surface 111, and a surface disposed opposite to the first surface 111 is designated as a second surface 112. It is understood that the second face 112 may be a plane, and disposed parallel to the first face 111; the second face 112 may also be a curved face. The peripheral surfaces between the first surface 111 and the second surface 112 and respectively connecting the first surface 111 and the second surface 112 are named as a first peripheral surface 113, and it is understood that the shape of the hair-planting base 110 may be racetrack, oval, circular, etc., and the shape of the first peripheral surface 113 is different depending on the shape of the hair-planting base 110.

It should be noted that, the shock absorbing member 200 is generally made of soft materials such as silica gel, and when the bristle base 110 contacts with teeth or gum tissue, the shock absorbing member 200 can play a role of buffering so as to avoid strong discomfort caused by direct contact of the bristle base 110 with teeth due to high-frequency vibration. In the prior art, the shock absorbing member 200 is often sleeved on the bristle planting base 110 through the first opening 220, and the connection manner is relatively easy to cause the shock absorbing member 200 to fall off, if falling off during brushing, the foreign body sensation in the oral cavity is easy to be caused, and if falling off during idling, the shock absorbing member 200 is easy to be lost.

Therefore, the shock absorbing member 200 in the embodiment of the present application is coated on the hair-planting base 110 by the secondary injection molding method, and better coating property can be obtained by the injection molding process, so that the shock absorbing member 200 and the hair-planting base Mao Ji are tightly attached. In addition, as shown in fig. 2, the hair-planting base 110 is further provided with a first injection molding groove 114, and the inner wall of the shock absorbing member 200 is convexly provided with a first connecting portion 230, and the first connecting portion 230 is inserted into the first injection molding groove 114 through an injection molding process.

The first injection molding groove 114 may be disposed on the first circumferential surface 113 as shown in fig. 2 and 3, and extend along the first direction as shown in fig. 3, and the corresponding first connecting portion 230 on the inner wall of the shock absorbing member 200 extends along the first direction, and as shown in fig. 4 and 5, when the shock absorbing member 200 is coated on the hair planting base 110 and the first connecting portion 230 is inserted into the first injection molding groove 114, the groove wall of the first injection molding groove 114 can limit the shock absorbing member 200 to move along the second direction relative to the hair planting base 110. Alternatively, the first injection molding groove 114 may be T-shaped or L-shaped, and includes a first groove section extending in the second direction and a second groove section extending in the first direction. The first groove section is arranged on the second surface 112, extends towards the interior of the hair-planting base 110 along the second direction, and is positioned at the tail end of the first groove section; correspondingly, the first connecting portion 230 is also T-shaped or L-shaped and is disposed in the first injection molding slot 114, and can limit the relative movement of the damper 200 and the hair-planting base 110 by the slot wall of the second slot section. Or the first injection groove 114 is provided on the first circumferential surface 113, extends obliquely toward the second surface 112, and penetrates the second surface 112. It is understood that the arrangement of the first injection groove 114 is not limited to the above.

Based on the above, the toothbrush head in the embodiment of the application is connected to the toothbrush head main body 100 through an injection molding process, and the inner wall of the shock absorbing member 200 is provided with the convex first connection part 230, and the outer wall of the bristle planting base 110 is provided with the concave first injection molding groove 114, so that on one hand, the contact area between the shock absorbing member 200 and the bristle planting base 110 can be increased, and a better shock absorbing effect is achieved; on the other hand, the insert-fit engagement of the first injection groove 114 and the first coupling groove can limit the relative displacement of the damper 200 and the hair-planting base 110, reducing the possibility of the damper 200 falling off.

In some embodiments, a first injection molding slot 114 is disposed through the bristle base 110. For example, in the embodiment shown in fig. 3, the hair-planting base 110 is a racetrack, and has two long sides and two arc sides, and the first injection molding groove 114 is disposed through the two long sides. Correspondingly, the first connecting portion 230 on the shock absorbing member 200 is disposed through the first injection molding slot 114, and two ends of the first connecting portion 230 are respectively connected with inner walls of two sides of the shock absorbing member 200. With this structure, after the injection molding is completed, it can be understood that the damper 200 is sleeved on the solid portion of the hair-planting base 110 from the first injection groove 114 to the second surface 112, and thus the damper 200 cannot be detached from the hair-planting base 110 without damaging the damper 200 or the hair-planting base 110.

Based on this design concept, the first injection molding groove 114 may also be provided through two arcuate edges; or the first injection molding groove 114 extends from the first circumferential surface 113 to penetrate the second surface 112 in an inclined manner; or the first injection molding groove 114 is a semicircular groove, two openings of the first injection molding groove 114 are both arranged on the second surface 112, and after injection molding is completed, the annular first connecting part 230 is sleeved on a solid part in the middle of the first injection molding groove 114, so that the fixed connection between the shock absorbing member 200 and the hair planting base 110 is completed.

Further, as shown in fig. 2, the first injection molding groove 114 is disposed on the first peripheral surface 113, extends parallel to the first surface 111 and penetrates the hair-planting base 110. In order to further increase the shock absorbing effect, as shown in fig. 3 and 5, a second injection groove 115 is provided on the second face 112, and the second injection groove 115 extends in a direction close to the first face 111 and communicates with the first injection groove 114. Therefore, the design of the second injection molding groove 115 facilitates the injection molding of the first injection molding groove 114, increases the contact area between the hair-planting base 110 and the shock absorbing member 200, and can release the vibration force of the back of the hair-planting base 110, thereby avoiding the discomfort caused by the hair-planting base 110 touching teeth.

Correspondingly, a second connecting portion 240 is disposed on the inner wall of the shock absorbing member 200 corresponding to the second injection molding slot 115, and the second connecting portion 240 is disposed through the injection molding slot and connected to the first connecting portion 230.

In some embodiments, as shown in fig. 3 and 4, the first peripheral surface 113 is further provided with a first shock absorbing groove 116, and the first shock absorbing groove 116 extends along the opposite direction of the first surface 111 and the second surface 112 and is disposed through the hair-planting base 110. As shown in fig. 3, two first shock absorbing grooves 116 are respectively arranged on two long sides of the runway-type hair planting base 110, and the contact area between the hair planting base 110 and the shock absorbing member 200 can be increased by the arrangement of the first shock absorbing grooves 116, so that the vibration force generated by high-frequency vibration can be released.

Correspondingly, the inner wall of the shock absorbing member 200 after injection molding is provided with a first shock absorbing protrusion 270 corresponding to the first shock absorbing groove 116, and the first shock absorbing protrusion 270 is inserted into the first shock absorbing groove 116.

In some embodiments, as shown in fig. 1, the brush head main body 100 further includes a handle 120 connected to the bristle planting base 110, the handle 120 is used to connect to a main body 400 of the electric toothbrush, and the damping member 200 is defined with a second opening 250 for the handle 120 to pass through, so that a part of the damping member 200 is sleeved on the handle 120, which improves the covering range of the damping member 200, thereby reducing the probability that the brush head main body 100 directly contacts with teeth, optimizing the use experience of the brush head of the toothbrush, and further reducing the possibility that the damping member 200 is separated and separated from the bristle planting base 110 due to the larger contact area and the sleeved structure of the damping member 200 sleeved on the handle 120.

In some embodiments, the outer peripheral surface of the shock absorbing member 200 is provided with a plurality of protruding portions 260 disposed at intervals, as shown in fig. 1 and 5, each protruding portion 260 is a semicircular protruding point, and the semicircular protruding point is disposed on the outer peripheral surface of the shock absorbing member corresponding to the second surface 112 of the bristle planting base 110, that is, the back surface of the toothbrush head. The front surface of the brush head is thus provided with bristles 130, which can be used for cleaning teeth, and the back surface is provided with protrusions 260, which can be used for cleaning tongue coating. The protruding part 260 and the main body of the shock absorbing member 200 are all integrally formed by injection molding, are made of soft materials such as silica gel, are soft in texture, and can reduce regurgitation caused by touching the tongue fur by the toothbrush head.

In some embodiments, as shown in fig. 6 and 7, the brush head body 100 further includes a handle 120 connected to the bristle setting base 110, and the toothbrush head is further provided with an overflow preventing member 300, wherein the overflow preventing member 300 may be coated on the handle 120 by two-shot molding, may be coated on the handle 120 by being sleeved on the handle 120 and then thermoplastic, or the overflow preventing member 300 may be made of an elastic material, may be connected to the handle 120 by being elastically deformed and then restored to be elastically deformed after being sleeved on the handle 120. Spill guard 300 includes a body portion for coupling with handle 120 and a spill guard 310 disposed over handle 120. The anti-overflow cap 310 is annular, the inner ring of which is connected to the main body, and the outer ring of which is a free end. Because the anti-overflow cover 310 is also made of soft materials such as silica gel, the anti-overflow cover 310 can be deformed, so that the anti-overflow cover 310 can be turned up to form a cover body structure, and can also be downward conformed to the appearance setting of the toothbrush head.

Specifically, as shown in fig. 6 and 7, the overflow preventing cap 310 has an opened state and a closed state, and when a user needs to use the electric toothbrush, the overflow preventing cap 310 is pushed toward the brush head to be deformed to be opened to form a cap structure as shown in fig. 7, one end of the overflow preventing cap 310 is connected with the body part, and the other end extends toward the shock absorbing member 200 to form an overflow preventing groove between the overflow preventing cap 310 and the body part. During brushing, if the toothpaste foam flows down along the brush head of the toothbrush, the anti-overflow cover 310 can prevent the toothpaste foam from flowing down further, so that the toothpaste foam is collected in the anti-overflow groove, and thus liquid such as the toothpaste foam is prevented from flowing onto the hand or the main body 400.

When the user uses the electric toothbrush, the overflow preventing cap 310 is pulled downward to be attached to the body 400 or the body portion of the overflow preventing member 300, that is, when the overflow preventing cap 310 is in the closed state as shown in fig. 6, one end of the overflow preventing cap 310 is connected to the body portion and the other end extends away from the shock absorbing member 200. Therefore, the anti-overflow groove is unfolded after the anti-overflow cover 310 is closed, dust is not easy to accumulate, and on the other hand, the appearance of the whole electric toothbrush is smooth, unobtrusive and attractive.

Further, the anti-overflow cover 310 is disposed at an end of the main body portion away from the shock absorbing member 200. As shown in fig. 7, when the toothbrush head of the present embodiment is applied to an electric toothbrush, the brush head body 100 of the toothbrush head is connected to the main body 400 of the electric toothbrush, a gap exists between the main body 400 and the brush head body 100, and there is a possibility of water inflow, dust seepage, etc., and therefore, the anti-overflow cover 310 is disposed at one end of the main body far away from the shock absorbing member 200, and when the anti-overflow cover 310 is in a closed state, the anti-overflow cover 310 can be attached to the main body 400 and cover the gap between the main body 400 and the brush head body 100, thereby playing a role of water and dust prevention.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
