Abstract

A replaceable natural food food teething device with a safety locking structure includes a base unit, a teething assembly, and a locking unit. The base unit has a handle and a support shaft integrally extended from the handle. The teething assembly is made of edible natural food material and has a through-hole for fitting onto the support shaft. The locking unit is located at the end of the support shaft away from the handle, clamping the teething assembly between the handle and the locking unit to form an axial locking structure. This keeps the teething assembly on the support shaft during use and, through its non-circular cross-section structure, restricts rotation, thereby improving structural stability.

Description

Replaceable natural food teething mortar with safety locking mechanism Technical Field

[0001] This invention relates to a structural improvement of a dental grinding device, and more particularly to a replaceable dental grinding device with a through-type support shaft and a safety locking structure. Prior Technology

[0002] It is well known that infants and toddlers often need to chew on objects to relieve gum discomfort during teething. Related products on the market can be broadly divided into two categories. One category consists of teething rings made of silicone, plastic, or other polymer materials, which are reusable but not edible. The other category includes teething biscuits or natural food products that can be directly chewed on. While these products are edible, they are mostly solid structures, and may crack or break due to concentrated force during chewing.

[0003] In addition, some replaceable teething products only use a sleeve or simple snap-fit ​​method to fix the eating parts. If they become loose during chewing, the teething components may detach from the supporting components.

[0004] Therefore, it is necessary to provide a structurally improved teething device that allows the edible teething components to be stably constrained to the support structure during chewing, thereby improving the structural stability during use. Summary of the Invention

[0005] The main purpose of this invention is to provide a replaceable natural food chewing tool with a safety locking structure, so that the edible chewing component can be stably restrained on the support member during chewing. Even if the chewing component is cracked or partially damaged, it can still maintain the axial restraint of the overall structure and prevent it from detaching from the support member.

[0006] To achieve the above objectives, the present invention comprises: a base unit having a handle portion and a support shaft integrally extending from the handle portion, the support shaft protruding outward from the handle portion; a molar assembly made of edible natural food material, the molar assembly having a shaft hole extending from one end to the other end, and being sleeved along the axial direction of the support shaft, so that the support shaft passes through the interior of the molar assembly; and a limiting locking unit disposed at the end of the support shaft away from the handle portion, so that the molar assembly is clamped between the handle portion and the limiting locking unit to form an axial limiting structure.

[0007] With the above structure, the support shaft forms a through-type internal support skeleton, and an axial limiting clamping structure is formed from the upper and lower ends, so that the molar assembly is axially restrained during the biting process. Even if cracks are caused by force, it is still restricted to the support shaft and will not detach as a whole.

[0008] In one embodiment of this invention, the cross-section of the support shaft may be non-circular, and the shaft hole has a corresponding non-circular inner edge to restrict the rotation of the gear assembly relative to the support shaft; the limiting locking unit may be threadedly fastened to one end of the support shaft; in one embodiment, the limiting locking unit has a limiting portion whose outer diameter is larger than the diameter of the shaft hole; the outer periphery of the limiting locking unit may be provided with a rounded bevel, and may be provided with at least one through vent hole.

[0009] Based on the above description, the features and effects of this novel invention are briefly summarized as follows:

[0010] 1. Through-type support structure: The support shaft runs through the inside of the molar assembly, so that the molar assembly is stably supported during the biting process.

[0011] 2. Double-end limiting clamping: The grip and the limiting locking unit form an axial clamping structure, reducing the possibility of the molar assembly disengaging.

[0012] 3. Anti-rotation design: The non-circular cross-section mating structure can limit the rotation of the grinding assembly and improve the stability of use.

[0013] IV. Safety Structure Configuration: The design of the limiting part, rounded corners and vent holes helps to improve the structural safety during use. Simple Explanation of the Diagram

Figure 3: Cross-sectional view of the present invention, illustrating the non-circular cross-sectional structure of the supporting shaft. Figure 4: Exploded view of the present invention. Figure 5: Schematic diagram of the use of this new invention. Implementation

[0015] The following description, in conjunction with Figures 1 to 5, illustrates one embodiment of the present invention. However, the figures shown are for illustrative purposes only and are not intended to limit the actual proportions, dimensions, or shape of the present invention.

[0016] As shown in Figures 1 to 4, the new replaceable natural food teething device with a safety locking structure includes a base unit 10, a teething component 20, and a limiting and locking unit 30.

[0017] The base unit 10 has a handle portion 11 and a support shaft 12 integrally extended from the handle portion 11. The support shaft 12 protrudes outward from the handle portion 11 and extends along an axial direction.

[0018] The molar assembly 20 is made of edible natural food material and has a shaft hole 21 that extends from one end to the other. The molar assembly 20 is sleeved along the axial direction of the support shaft 12, so that the support shaft 12 passes through the interior of the molar assembly 20.

[0019] The limiting and locking unit 30 is disposed at one end of the support shaft 12 away from the handle portion 11, so that the molar assembly 20 is clamped between the handle portion 11 and the limiting and locking unit 30, thereby forming an axial limiting structure to restrict the axial movement of the molar assembly 20 along the support shaft 12.

[0020] In one embodiment of this invention, as shown in FIG3, the cross-section of the support shaft 12 is non-circular, and the shaft hole 21 has a corresponding non-circular inner edge, thereby restricting the rotation of the tooth assembly 20 relative to the support shaft 12.

[0021] In one embodiment, the limiting locking unit 30 is threadedly locked to one end of the support shaft 12.

[0022] In one embodiment, the limiting and locking unit 30 has a limiting part 31, the outer diameter of which is larger than the diameter of the shaft hole 21, so as to form the axial limiting structure.

[0023] In one embodiment, the limiting and locking unit 30 has a rounded bevel angle 32 on its outer periphery.

[0024] In one embodiment, the limiting and locking unit 30 is provided with at least one through vent 33.

[0025] When assembling as shown in Figures 1 to 4, first, the molar assembly 20 is sleeved along the axial direction of the support shaft 12, so that the support shaft 12 passes through the shaft hole 21. Then, the limiting locking unit 30 is attached to one end of the support shaft 12 away from the handle portion 11, so that the molar assembly 20 is clamped between the handle portion 11 and the limiting locking unit 30.

[0026] As shown in Figure 5, during use, the user holds the handle 11, allowing the teething component 20 to be chewed on by infants and young children. Because the teething component 20 is supported by the through-through support shaft 12 and restricted by the axial limiting structure of the limiting locking unit 30, the teething component 20 is held on the support shaft 12 during use.

[0027] In summary, this new invention provides internal support for the molar assembly 20 during use through the through-type configuration of the support shaft 12; and restricts the molar assembly 20 axially through the axial limiting structure formed by the handle portion 11 and the limiting locking unit 30; furthermore, the non-circular cross-section structure restricts rotation, and the configuration of the limiting portion 31, the arc-shaped guide angle 32, and the vent hole 33 ensures the overall structure has stability and safety.
