Description

Technical Field

[0001] The utility model relates to the field of toothbrushes, in particular to a toothbrush head with high elasticity and a toothbrush. Background Art

[0002] A toothbrush is a cleaning tool used to clean teeth and interdental spaces, generally including a brush head and a brush handle. To ensure the structural strength of the toothbrush head, the brush head and brush handle of a traditional toothbrush are usually made of relatively rigid plastic using injection molding. When brushing teeth, the pressure exerted by the bristles on the teeth or other oral tissues is generally controlled manually, but people often cannot control the pressure applied during brushing well, and will unconsciously apply too much force, thereby injuring the gums or other oral tissues. However, if the pressure applied is too small, the cleaning force will be insufficient.

[0003] Therefore, the neck of a toothbrush is designed to be particularly thin so that the toothbrush can bend elastically when subjected to force, thereby reducing the pressure on teeth or other oral tissues. However, the toothbrush is made of plastic with low elasticity, so the neck must be designed to be extremely steep to make the toothbrush have greater elasticity, and the extremely steep neck will greatly reduce the structural strength of the toothbrush head. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The utility model provides a toothbrush head with high elasticity and a toothbrush, which can at least solve the technical problem of how to improve the elasticity of the toothbrush head and ensure the structural strength of the toothbrush head.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a toothbrush head with high elasticity and a toothbrush, comprising:

[0008] head;

[0009] The neck portion comprises an elastic body and an elastic sleeve, wherein the elastic body comprises two gradually expanding sections, and the ends with the largest cross-sectional areas of the two gradually expanding sections are respectively used to connect with the head and the handle of the toothbrush, and the elastic sleeve is arranged on the outside of the elastic body, and the elasticity of the elastic sleeve is greater than that of the elastic body;

[0010] Wherein, the toothbrush head includes an initial state and a use state;

[0011] When the toothbrush head is in the initial state, one end of the elastic sleeve abuts against the connection between the gradually expanding section and the head, and the other end abuts against the connection between the gradually expanding section and the brush handle;

[0012] When the toothbrush head is in use, the head is subjected to force and is linked to the elastic body to bend along the force direction. The elastic body is linked to the elastic sleeve to bend. The elastic sleeve includes a first part facing away from the bending direction and a second part facing the bending direction. The two ends of the first part are away from the two gradually expanding sections, and the two ends of the second part are close to the connection between the two gradually expanding sections.

[0013] It is further provided that the cross section of the elastic body is elliptical, the length direction of the cross section of the elastic body is perpendicular to the force direction, and the width direction of the cross section of the elastic body is parallel to the force direction.

[0014] It is further provided that the aforementioned elastic body and the elastic sleeve are coaxially or eccentrically arranged, and in any cross section of the elastic sleeve, the maximum thickness of the first part in the force direction is not less than the maximum thickness of the second part in the force direction.

[0015] It is further provided that the aforementioned elastic body and the head are integrally connected, and the elastic body and the head are integrally formed of a hard material, and the elastic sleeve is integrally formed of a soft material.

[0016] It is further provided that the toothbrush head with high elasticity also includes a reinforcing portion, which is arranged on a gradually expanding section where the elastic body is connected to the brush handle, and the rigidity of the reinforcing portion is greater than the rigidity of the elastic body.

[0017] It is further provided that the aforementioned reinforcement portion is provided with a connecting groove for connecting to the brush handle.

[0018] The utility model also provides a toothbrush, comprising a brush handle and the toothbrush head, wherein the top end of the brush handle is connected to the toothbrush head.

[0019] It is further provided that the toothbrush also includes a base, the brush handle is plugged into and supported on the base, and the base is provided with a slot for inserting the bottom end of the brush handle.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the toothbrush head and toothbrush provided by the utility model have the following beneficial effects:

[0022] 1. The neck of the toothbrush head provided by the utility model includes an elastic body and an elastic sleeve. The elastic body includes two gradually expanding sections, so that the elastic body as a whole is thick at both ends and thin in the middle. The slender elastic body can make the neck have greater elasticity. In this way, the toothbrush head can bend elastically to a greater extent when subjected to force, thereby reducing the pressure exerted by the user on the teeth or other oral tissues, providing a softer brushing action, inhibiting excessive brushing, and greatly reducing potential damage to oral tissues such as the tooth surface or oral mucosa, and the elastic body is covered with an elastic sleeve, which can play a buffering role, further reducing the potential damage to oral tissues such as the tooth surface or oral mucosa, and the elastic sleeve can also improve the structural strength of the neck, effectively reducing the risk of neck breakage, thereby ensuring the overall structural strength of the toothbrush head.

[0023] 2. The elastic body is connected to the head and the brush handle through the end with the largest cross-sectional area of ​​the two gradually expanding sections, which can ensure the structural strength of the connection between the elastic body and the head and the brush handle, thereby ensuring the overall structural strength of the toothbrush head.

[0024] 3. When the toothbrush head is in use, the head is subjected to force and one end of the elastic body connected to the head is bent toward the other end along the force direction. Since the elasticity of the elastic sleeve is greater than that of the elastic body, the bending of the elastic body can link the elastic sleeve (including the first part and the second part) to bend along the force direction. When the elastic sleeve is bent, the curvature of the second part is greater than that of the elastic body, and the curvature of the first part is less than that of the elastic body, so that the two ends of the second part are further pressed against the connection between the two gradually expanding sections, playing a role in stably supporting the elastic body, thereby ensuring the structural strength of the neck and further reducing the risk of neck breakage, while the two ends of the first part are correspondingly away from the two gradually expanding sections, thereby reducing the connection area between the neck and the head and the brush handle, and further improving the elasticity of the toothbrush head.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The utility model provides a toothbrush head with high elasticity, which is used to solve the problem of how to improve the elasticity of the toothbrush head and ensure the structural strength of the toothbrush head.

[0037] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of a toothbrush head and a toothbrush in an embodiment. Figure 2 1 is a longitudinal cross-sectional view of a toothbrush head with high elasticity in an embodiment. The toothbrush head with high elasticity comprises a head 1 and a neck 2.

[0038] The neck portion 2 includes an elastic body 21 and an elastic sleeve 22 .

[0039] The elastic body 21 includes two gradually expanding sections 211, and the ends with the largest cross-sectional areas of the two gradually expanding sections 211 are respectively used to connect with the head 1 and the brush handle 4 of the toothbrush, so that the elastic body 21 as a whole is thick at both ends and thin in the middle. The slender elastic body 21 can make the neck 2 have greater elasticity. In this way, the toothbrush head can bend elastically to a greater extent when subjected to force, thereby reducing the pressure exerted by the user on the teeth or other oral tissues, providing a softer brushing action, inhibiting excessive brushing, and greatly reducing potential damage to oral tissues such as the tooth surface or oral mucosa.

[0040] The elastic sleeve 22 is sleeved on the outside of the elastic body 21, and the elasticity of the elastic sleeve 22 is greater than that of the elastic body 21. In this way, the elastic sleeve 22 can bend with the elastic body 21, and the elastic sleeve 22 can play a buffering role, further reducing potential damage to the tooth surface or oral mucosa and other oral tissues. The elastic sleeve 22 can also improve the structural strength of the neck 2, effectively reducing the risk of neck 2 fracture, thereby ensuring the overall structural strength of the toothbrush head.

[0041] The toothbrush head provided by the utility model includes an initial state and a use state. When the toothbrush head is in the initial state, one end of the elastic sleeve 22 abuts against the connection between the gradually expanding section 211 and the head 1, and the other end of the elastic sleeve 22 abuts against the connection between the gradually expanding section 211 and the brush handle 4; when the toothbrush head is in the use state, the head 1 is subjected to force and the elastic body 21 is linked to the end connected to the head 1 to bend toward the other end along the force direction, and the elastic body 21 is linked to the elastic sleeve 22 to bend accordingly. The elastic sleeve 22 includes a first part 221 facing away from the bending direction and a second part 22 facing the bending direction. 2. When the elastic sleeve 22 is bent, the curvature of the second part 222 is greater than the curvature of the elastic body 21, and the curvature of the first part 221 is less than the curvature of the elastic body 21, so that the two ends of the second part 222 are further pressed against the connection of the two gradually expanding sections 211, playing a role in stably supporting the elastic body 21, thereby ensuring the structural strength of the neck 2 and further reducing the risk of the neck 2 breaking, while the two ends of the first part 221 are correspondingly away from the two gradually expanding sections 211, thereby reducing the connection area between the neck 2 and the head 1 and the handle 4, and further improving the elasticity of the toothbrush head.

[0042] The cross-sectional area of ​​the above-mentioned gradually expanding section 211 gradually increases along the radial direction of the elastic body 21. The ends with the smallest cross-sectional areas of the two gradually expanding sections 211 can be directly connected as one piece, and the ends with the largest cross-sectional areas of the two gradually expanding sections 211 are respectively connected to the head 1 and the brush handle 4, which can ensure the structural strength of the connection between the elastic body 21 and the head 1 and the brush handle 4, thereby ensuring the overall structural strength of the toothbrush head.

[0043] See also Figure 3 As shown, Figure 3 It is a transverse cross-sectional view of a toothbrush head with high elasticity in an embodiment. In one embodiment of the elastic body 21, the cross section of the elastic body 21 is elliptical, the length direction of the cross section of the elastic body 21 is perpendicular to the force direction, and the width direction of the cross section of the elastic body 21 is parallel to the force direction. In this way, the elastic body 21 is flat, and the length of the elastic body 21 parallel to the force direction is much smaller than the length perpendicular to the force direction, which makes the elastic body 21 easier to bend along the force direction and undergo elastic deformation, while the length perpendicular to the force direction is larger, which can ensure the structural strength of the elastic body 21.

[0044] See also Figure 3 As shown, in one embodiment of the elastic body 21, the elastic body 21 and the elastic sleeve 22 are coaxially or eccentrically distributed, and in any cross section of the elastic sleeve 22, the maximum thickness of the first part 221 in the force direction is not less than the maximum thickness of the second part 222 in the force direction. In this way, it is effectively avoided that the supporting force of the second part 222 is too large, which greatly reduces the elastic force of the elastic body 21 and makes it difficult for the elastic body 21 to bend.

[0045] In this embodiment, the elastic body 21 and the elastic sleeve 22 are coaxially distributed.

[0046] The elastic body 21 is integrally connected to the head 1, and the elastic body 21 and the head 1 are integrally formed of hard materials, and the elastic sleeve 22 is integrally formed of soft materials. In this way, the elastic body 21 integrally formed of hard materials can ensure the overall structural strength of the toothbrush head, while the soft elastic sleeve 22 can facilitate the elastic sleeve 22 to bend and deform with the elastic body 21.

[0047] See also Figure 2 As shown, the toothbrush head further includes a reinforcing portion 3, which can be mounted on the gradually expanding section 211 connecting the elastic body 21 and the brush handle 4 by means of snap-fitting or embedding, and the rigidity of the reinforcing portion 3 is greater than the rigidity of the elastic body 21. In this way, the reinforcing portion 3 can improve the structural strength of the connection between the elastic body 21 and the brush handle 4, thereby ensuring the overall structural strength of the toothbrush head.

[0048] See also Figure 2 As shown, the reinforcement portion 3 has a connection groove 31 for connecting the brush handle 4.

[0049] The reinforcement part 3 can be made of metal material in one piece. Figure 4 As shown, Figure 4 The exploded diagram of the structure of the toothbrush in the embodiment shows that the top of the brush handle 4 has a metal plug rod 41 which is plugged into the connecting groove 31. In this way, the brush handle 4 is rigidly connected to the gradually expanding section 211, thereby improving the structural strength of the connection between the elastic body 21 and the brush handle 4.

[0050] See also Figure 1 and Figure 4 As shown, the utility model also provides a toothbrush, including a brush handle 4 and the above-mentioned toothbrush head, wherein the top of the brush handle 4 is connected to the toothbrush head. The specific implementation process of the toothbrush head can refer to the above description, and this embodiment will not be repeated here. Since the toothbrush head has the above-mentioned technical effects, the toothbrush having the toothbrush head also has the corresponding technical effects.

[0051] When the same brushing pressure is applied to the toothbrush provided by the utility model and the existing toothbrush with a rigid neck, the reaction force measured at the toothbrush head of the toothbrush provided by the utility model is 2.5 times lower than that of the existing toothbrush with a rigid neck. It can be seen that compared with the existing toothbrush with a rigid neck, the toothbrush provided by the utility model can provide a softer brushing action, inhibit excessive brushing, and greatly reduce potential damage to oral tissues such as the tooth surface or oral mucosa.

[0052] See also Figure 4 As shown, the toothbrush further comprises a base 5, on which the brush handle 4 is inserted and supported, and the base 5 has a slot 51 for inserting the bottom end of the brush handle 4.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
