[0041] like Figure 1 , Figure 2 As shown, this exemplary embodiment provides a tooth glue, comprising:

[0042] A hand-held portion 100, an arc-shaped blocking portion 200 and a rubber head portion 300;

[0043] The hand-held portion 100 is disposed on one side of the arc-shaped blocking portion 200;

[0044] The rubber head 300 includes a connecting portion 310 and a bite portion 320. The connecting portion 310 is disposed on a side of the arc-shaped blocking portion 200 away from the hand-held portion 100. The bite portion 320 is connected to an end of the connecting portion 310 away from the arc-shaped blocking portion 200, and the bite portion 320 is disposed at an angle with the connecting portion 310. Figure 1 As shown, the handheld portion 100, the arc-shaped blocking portion 200 and the rubber head portion 300 can all be made of soft silicone material, wherein the handheld portion 100 is roughly cylindrical, the arc-shaped blocking portion 200 is roughly umbrella-shaped, and the rubber head portion 300 includes two parts: a connecting portion 310 and a bite portion 320. It should be noted that in order to facilitate the holding of the handheld portion 100 by infants and young children, in another embodiment, the handheld portion 100 can also be roughly in the shape of a pull ring, and the present application does not limit the specific structure of the handheld portion 100.

[0045] In an embodiment of the present application, the hand-held part 100 can be set on the concave surface of the arc-shaped blocking part 200, and the rubber head part 300 can be set on the convex surface of the arc-shaped blocking part 200, or the hand-held part 100 can be set on the convex surface of the arc-shaped blocking part 200, and the rubber head part 300 can be set on the concave surface of the arc-shaped blocking part 200.

[0046] Reference Figure 1 , Figure 2 As shown, in the embodiment of the present application, the hand-held portion 100 can be arranged on the concave surface of the arc-shaped blocking portion 200, and the gum head portion 300 can be arranged on the convex surface of the arc-shaped blocking portion 200. Among them, one end of the hand-held portion 100 is connected to the concave surface of the arc-shaped blocking portion 200, so that the arc-shaped blocking portion 200 can be covered on the top of the hand-held portion 100, and the connecting portion 310 is connected to the convex surface of the arc-shaped blocking portion 200. When the infant holds the hand-held portion 100 and bites the gum head portion 300, the mouth and teeth are located on one side of the arc-shaped blocking portion 200, and the hand is located on the other side of the arc-shaped blocking portion 200. The arc-shaped blocking portion 200 can separate the hand and the teeth, and the arc-shaped blocking portion 200 can also play a limiting role, which can prevent the infant from putting the gum into the mouth too deep. In addition, the arc-shaped blocking portion 200 can also cover the infant's hand under its concave surface, thereby preventing the infant from chewing or biting the hand.

[0047] Continue to refer to Figure 1 , Figure 2 The hand-held portion 100 can be connected to the arc-shaped blocking portion 200 at the vertex position of the concave surface of the arc-shaped blocking portion 200, and the connecting portion 310 can be connected to the arc-shaped blocking portion 200 at the vertex position of the convex surface of the arc-shaped blocking portion 200. The hand-held portion 100 and the connecting portion 310 are coaxially arranged, so that it is convenient for infants and young children to hold the hand-held portion 100 to determine the position of the rubber head portion 300 when using it, so that they can easily put the rubber head portion 300 into their mouths.

[0048] In addition, if Figure 1 , Figure 2 As shown, the bite portion 320 and the connecting portion 310 are arranged at an angle, that is, the bite portion 320 does not extend along the axial direction of the connecting portion 310, but extends at an angle to the connecting portion 310, so that a receiving area 330 can be formed between the bite portion 320, the connecting portion 310 and the convex surface of the arc-shaped blocking portion 200. When the infant is in use, the lips are located in the receiving area 330, and the receiving area 330 can fit with the infant's lips. The bite portion 320 and the connecting portion 310 are arranged at an angle, which can facilitate the bite portion 320 to extend into the inner gum position of the infant, thereby massaging the inner gum of the infant. In the prior art, the biting portion 320 is coaxially arranged with the connecting portion 310, that is, the biting portion 320 directly extends along the axial direction of the connecting portion 310. If one wishes to massage the gums inside the gums of an infant, the entire toothpaste needs to be tilted upward at a large angle to contact the inner gums of the infant. However, the biting portion 320 in the present application is arranged at an angle to the connecting portion 310, and the inner gums of the infant can be contacted at a smaller tilt angle.

[0049] The embodiment of the present application can prevent infants from inserting the teether too deep into their mouths by providing the arc-shaped blocking portion 200, and can also protect the hands of infants and prevent them from biting their hands. The connecting portion 310 and the biting portion 320 are arranged at an angle. On the one hand, a receiving area 330 can be formed between the biting portion 320, the connecting portion 310 and the arc-shaped blocking portion 200, which is convenient for fitting with the lips of infants and on the other hand, it is also convenient for inserting into the inner gum position of infants and massaging the inner gums. The head of the teether provided in this embodiment can also be sucked by infants and achieve a soothing effect.

[0050] like Figure 1 , Figure 2 As shown, in the embodiment of the present application, the position where the bite portion 320 is connected to the connecting portion 310 forms an arc transition; the position where the connecting portion 310 is connected to the arc-shaped blocking portion 200 forms an arc transition. Figure 1 As shown, one end of the connecting portion 310 is connected to the biting portion 320, and the connecting position forms an arc transition, and the other end of the connecting portion 310 is connected to the arc-shaped blocking portion 200, and the connecting position also forms an arc transition, so the surface of the entire accommodating area 330 is a smoothly connected surface, so that it can fit well with the lips of infants and young children without producing a foreign body sensation.

[0051] like Figure 1 , Figure 2 As shown, in the embodiment of the present application, the middle of the bite portion (320) is thicker than the two ends. For example, in the embodiment of the present application, the cross section of the bite portion 320 increases first and then decreases from one end close to the connection portion 310 to the other end, so that the two ends of the bite portion 320 are thinner and the middle is thicker, so that the rubber head 300 as a whole can form a shape from thin to thick and then to thin. The end of the bite portion 320 close to the connection portion 310 is thinner, which can facilitate the thicker part in the middle to contact the inner gums of infants and young children, and play a better massage effect on the inner gums. On the other hand, it can facilitate infants and young children to suck and achieve a soothing effect.

[0052] like Figure 1 , Figure 2 As shown, in the embodiment of the present application, the end of the bite portion 320 away from the connection portion 310 is a convex arc surface. The end surface of the bite portion 320 away from the connection portion 310 is a convex arc surface, which will not cause puncture or stab injuries to the infant's mouth, and can protect the infant's mouth.

[0053] like Figure 3 , Figure 4 , Figure 5As shown, in the embodiment of the present application, the cross section of the connecting portion 310 perpendicular to its own axis and the cross section of the engaging portion 320 perpendicular to its own axis are both shaped circles; the length of the shaped circle formed by the cross section of the connecting portion 310 perpendicular to its own axis and the shaped circle formed by the cross section of the engaging portion 320 perpendicular to its own axis are both greater than the width, and the engaging portion 320 is arranged at an angle to the connecting portion 310 along the width direction of the shaped circle formed by the cross section perpendicular to its own axis.

[0054] like Figure 4 , Figure 5 As shown, Figure 4 The irregular circle r1 is formed by the cross section of the connecting portion 310 perpendicular to its own axis. Figure 5 The irregular circle r2 is formed by the cross section of the engaging portion 320 perpendicular to its own axis. The irregular circles r1 and r2 are neither perfect circles nor ellipses, but are smooth and flat circles roughly similar to ellipses, so that the engaging portion 320 and the connecting portion 310 are roughly flat. Among them, d1 is the width direction of r1, d2 is the length direction of r1, d3 is the width direction of r2, d4 is the length direction of r2, d2>d1, d4>d3, d1 and Figure 3 The dashed line s1 in the figure corresponds to d3, and Figure 3 The dotted line s2 in Figure 3 In the orientation shown, the bite portion 320 is bent to the right and is set at an angle with the connection portion 310, that is, the bite portion 320 is set at an angle with the connection portion (310) along the width direction of the special-shaped circle formed by the cross section perpendicular to its own axis. As a result, the wider directions (d2 and d4) of the connection portion 310 and the bite portion 320 can provide a larger bite area, and the narrower directions (d1 and d3) of the connection portion 310 and the bite portion 320 are flush with the upper and lower gums of infants and young children, which can reduce the range of the infant's mouth opening when using the teether, thereby avoiding the discomfort caused by the infant's excessive mouth opening. This flat round design of the head of the teether can prevent infants and young children from buck teeth to a certain extent.

[0055] like Figure 3 , Figure 5 As shown, in the embodiment of the present application, the distance between the vertex of the arc formed by the cross section of the bite portion 320 perpendicular to its own axis and the axis of the bite portion 320 on the side close to the arc blocking portion 200 is greater than the distance between the vertex of the arc of the special-shaped circle on the side away from the arc blocking portion 200 and the axis of the bite portion 320. Figure 3 In the orientation shown, the engaging portion 320 is bent to the right and is arranged at an angle with the connecting portion 310. Figure 3 The side of the middle engaging portion 320 close to (bending toward) the arc-shaped blocking portion 200 is the right arc surface, and the side away from the arc-shaped blocking portion 320 is the left arc surface, as shown in FIG5 . Figure 5The arc on the left side of r2 corresponds to Figure 3 The middle occlusal portion 320 is located on the arc surface on the left side, and the arc line on the right side of r2 corresponds to Figure 3 The middle occlusal portion 320 is located on the arc surface on the right side, d5 represents the distance between the vertex of the arc line on the side away from the arc blocking portion 200 and the axis of the occlusal portion 320, d6 represents the distance between the vertex of the arc line on the side close to the arc blocking portion 200 and the axis of the occlusal portion 320, d6 is greater than d5, that is, the arc surface of the occlusal portion 320 on the side away from the arc blocking portion is relatively flat, while the arc surface on the side close to the arc blocking portion is relatively protruding. When biting, the arc surface on the left side is relatively flat and easy to bear force, which is convenient for infants and young children to apply biting force to it, while the arc surface on the right side is more protruding and easy to contact with the inner gums, which is convenient for massaging the gums of infants and young children.

[0056] like Figure 6 As shown, in the embodiment of the application, the angle between the bite portion 320 and the connection portion 310 is greater than 0 degrees and less than or equal to 90 degrees. By setting the angle A between the bite portion 320 and the connection portion 310 to be less than or equal to 90 degrees and greater than 0 degrees, such as 30 degrees, 45 degrees, 60 degrees, and 85 degrees, the accommodation area 330 formed can better fit the lips of infants and young children, and it is also convenient to extend the bite portion 320 to the inner gums of infants and young children.

[0057] like Figure 6 As shown, in the embodiment of the present application, the length of the adhesive head 300 extending from the arc-shaped blocking portion 200 is between 20 mm and 30 mm. The length L1 of the adhesive head 300 extending from the arc-shaped blocking portion 200 is set between 20 mm and 30 mm. Within this size range, it can be ensured that the adhesive head will not extend too deep into the infant's mouth.

[0058] like Figure 1 , Figure 2As shown, in the embodiment of the present application, the hand-held part 100 is smoothly connected to the arc-shaped blocking part 200 at the top of the concave surface of the arc-shaped blocking part 200, and the concave surface of the arc-shaped blocking part 200 is provided with a plurality of reinforcing ribs 220, and the reinforcing ribs 220 extend from one end where the hand-held part 100 is connected to the arc-shaped blocking part 200 to the edge of the concave surface of the arc-shaped blocking part 200. The arc-shaped blocking part 200 is roughly umbrella-shaped or hemispherical, and the hand-held part 100 is smoothly connected to the arc-shaped blocking part 200 at the top of the concave surface of the arc-shaped blocking part 200, that is, the center point position, and the concave surface of the arc-shaped blocking part 200 is provided with a plurality of reinforcing ribs 220, and the plurality of reinforcing ribs 220 all extend from the center position of the concave surface of the arc-shaped blocking part 200 to the edge of the concave surface, and the reinforcing ribs 220 can increase the strength of the arc-shaped blocking part 200. In addition, the reinforcing rib 220 extends from one end of the concave surface located at the central vertex of the concave surface to the outer wall of the hand-held part 100, that is, the reinforcing rib 220 extends from the concave surface of the arc-shaped blocking part 200 to the outer wall of one end where the hand-held part 100 and the arc-shaped blocking part 200 are connected, thereby connecting the concave surface of the arc-shaped blocking part 200 with the hand-held part 100, playing the role of pulling the concave surface of the arc-shaped blocking part 200, and further maintaining the concave surface of the arc-shaped blocking part 200 always facing the hand-held part 100, preventing the arc-shaped blocking part 200 from flipping toward the side of the bite part 320.

[0059] like Figure 2 As shown, in the embodiment of the present application, at least one vent hole 210 is provided on the arc-shaped blocking portion 200, and the vent hole 210 runs through from the convex surface to the concave surface of the arc-shaped blocking portion 200. Since the entirety of the tooth gel is made of soft silicone, the arc-shaped blocking portion 200 will inevitably have the risk of turning over to the side of the bite portion 320. When the arc-shaped blocking portion 200 turns over to the side of the bite portion 320, there is a risk of being adsorbed on the mouth and nose of the infant and young child, causing suffocation. Therefore, the vent hole 210 is provided on the arc-shaped blocking portion 200, which can prevent the arc-shaped blocking portion 200 from being adsorbed on the mouth and nose of the infant and young child when turning over to the side of the gum head 300, causing suffocation.

[0060] like Figure 1 , Figure 2As shown, in the embodiment of the present application, the diameter of the end of the hand-held part 100 away from the rubber head 300 is greater than the diameter of the end of the hand-held part 100 close to the rubber head 300. For example, the diameter of the hand-held part 100 can be reduced first and then increased from the end connected to the arc-shaped blocking part 200 to the other end, so that the hand-held part 100 as a whole is thin in the middle and thick at both ends, which is convenient for infants to hold, and the end of the hand-held part 100 away from the arc-shaped blocking part 200 has a thicker diameter, which can also prevent infants from putting this end into their mouths. For another example, the end of the hand-held part 100 away from the rubber head 300 can be a cylindrical shape with a larger diameter, and the end close to the rubber head 300 can be a cylindrical shape with a smaller diameter, and a circular arc transition can be made in the middle. This design of the end with a larger diameter can also prevent it from being put into the mouth of infants, and the middle transition section can also facilitate holding.

[0061] like Figure 6 As shown, in the embodiment of the present application, the distance between the edge of the arc-shaped blocking portion 200 closest to the hand-held portion 100 and the end of the hand-held portion 100 away from the rubber head 300 is between 20 mm and 30 mm. Among them, the distance L2 between the edge of the arc-shaped blocking portion 200 and the end of the hand-held portion 100 away from the rubber head 300 is set between 20 mm and 30 mm, even if the infant puts one end of the hand-held portion 100 into the mouth, it can be avoided to a certain extent that the hand-held portion enters too deep into the infant's mouth and causes harm to the infant.

[0062] like Figure 7 As shown, in the embodiment of the present application, the edge of the arc-shaped blocking portion 200 is wavy. Figure 1 , Figure 2 , Figure 6 In the embodiment, the edges of the arc-shaped blocking portion 200 are located on the same plane, while in the present embodiment, the edges of the arc-shaped blocking portion 200 are located on an undulating wavy arc surface. Compared with the design located on the same plane, this shape can better attract the interest of infants and young children and improve its playability.

[0063] like Figure 2 As shown, in the embodiment of the present application, a lanyard hole 110 is provided at one end of the hand-held portion 100 away from the gum head 300. The lanyard hole 110 is provided at one end of the hand-held portion 100 away from the gum head 300, so that a lanyard can be tied to the gum. When the gum is idle, the lanyard can be used to hang the gum for easy storage.

[0064] In the embodiment of the present application, a hook is provided at one end of the handheld portion 100 away from the glue head 300. A hook is provided at one end of the handheld portion 100 away from the glue head 300, and the hook can be integrally formed with the handheld portion. When the tooth gel is idle, the tooth gel can be hung on the hook for easy storage.

[0065] In another embodiment of the present application, the engaging portion 320 and the connecting portion 310 of the rubber head portion 300 , the arc-shaped supporting portion and the hand-held portion 100 may be integrally formed to simplify the manufacturing process.

[0066] In another embodiment of the present application, the rubber head 300 is solid. The connecting portion 310 and the bite portion 320 can be both solid, and the rubber head 300 is set as a solid structure as a whole, which can increase its bite resistance. In addition, the solid rubber head 300 has a better massage effect.

[0067] In the embodiment of the present application, the curved blocking portion 200 is provided to prevent infants from inserting the teether too deep into their mouths, and also to protect the hands of infants and prevent them from biting their hands. The connecting portion 310 and the biting portion 320 are arranged at an angle, so that, on the one hand, a receiving area 330 can be formed between the biting portion 320, the connecting portion 310 and the curved blocking portion 200, so that it can fit the lips of infants and, on the other hand, it can also be easily inserted into the inner gum position of infants and massage the inner gums.

[0068] Finally, it should be noted that the above embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited thereto. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above embodiments within the technical scope disclosed by the utility model, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the utility model, and should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.

[0069] Through the above description, the embodiments of the present application provide at least the following technical solutions, but are not limited thereto:
