[0034] The embodiments of the present utility model will be further described below with reference to the drawings.

[0035] Please refer to the attached Figures 1-9A toothbrush handle connection structure shown includes a connection unit 1 and at least one special-shaped block matching unit 3; wherein the connection unit 1 has a socket 2; the socket 2 is formed at the bottom end of the connection unit 1 for the connecting rod 72 of the toothbrush handle 7 to be inserted; wherein the special-shaped block matching unit 3 includes a receiving groove 31 provided on the side wall of the socket 2, a first matching block 32 provided in the receiving groove 31, and a second matching block 33 provided in the receiving groove 31; there is a special-shaped channel 34 for the special-shaped block 723 to pass through between the first matching block 32 and the second matching block 33; when the special-shaped block 723 is located in the special-shaped channel 34, the first matching block 32 applies a force from the upper end of the special-shaped block 723 through deformation, and the second matching block 33 applies a force from the lower end of the special-shaped block 723 through deformation to limit the axial movement of the special-shaped block 723 along the connection unit 1.

[0036] Please continue to refer to Figures 3-5 , which shows a schematic model diagram of the toothbrush handle 7 in some existing embodiments; the toothbrush handle 7 includes a hand-held portion 71 and a connecting rod 72 provided at the upper end of the hand-held portion 71; the connecting rod 72 includes an upper connecting rod section 721 and a lower connecting rod section 722 connected to each other; a plurality of straight locking blocks 724 and a special-shaped block 723 are provided on the outer wall circumference of the lower connecting rod section 722; the special-shaped block 723 includes a first convex block 7231 protruding to one side and a second convex block 7232 protruding to the other side.

[0037] According to the structure of the toothbrush handle 7 described above, in actual use, the present invention includes a connection unit 1 and a socket 2, and the toothbrush handle 7 is matched with the connection unit 1 by inserting the connecting rod 72 into the socket 2, and the connection unit 1 and the socket 2 are easy to be processed with bamboo materials; it also includes a special-shaped block matching unit 3, wherein the special-shaped block matching unit 3 includes a receiving groove 31 that is easy to be processed with bamboo materials, and a first matching block 32 and a second matching block 33 that are easy to be independently processed with bamboo materials. When the first matching block 32 and the second matching block 33 are arranged in the receiving groove 31, a special-shaped channel 34 is formed between them for the special-shaped block 723 to enter and cooperate with it; and when the special-shaped block 723 is located in the special-shaped channel 34, the first matching block 32 and the second matching block 33 can apply forces to the upper and lower ends of the special-shaped block 723 through deformation, making the cooperation between the special-shaped block 723 and the special-shaped block matching unit 3 closer, so as to better transmit the vibration of the toothbrush handle 7.

[0038] Please continue to refer to Figure 2 , Figure 7 , wherein the receiving groove 31 includes a first side wall 311 provided on one side and a second side wall 312 provided on the other side; one of the first matching block 32 and the second matching block 33 is provided on the first side wall 311, and the other is provided on the second side wall 312.

[0039] In this setting, the receiving groove 31 provides an installation space for the first engaging block 32 and the second engaging block 33, enabling the first engaging block 32 and the second engaging block 33 to neither affect the insertion of the connecting rod 72 into the insertion hole 2 nor prevent them from forming a fit with the shaped block 723. Moreover, when the first engaging block 32 and the second engaging block 33 are disposed in the receiving groove 31, they can apply forces to the shaped block 723 from both sides, making the shaped block 723 more tightly fixed when it is in the shaped channel 34, which is beneficial to the cooperation between the toothbrush handle 7 and the toothbrush handle connection structure.

[0040] Please continue to refer to Figure 2 、 Figure 7 、 Figure 9 , wherein, the first engaging block 32 includes a first fixing section 321 and a first movable section 322; the first fixing section 321 is fixed to the lower end of the first side wall 311; the first movable section 322 is arranged to deform towards the first side wall 311 when the shaped block 723 is in the shaped channel 34; the second engaging block 33 includes a second fixing section 331 and a second movable section 332; the second fixing section 331 is fixed to the upper end of the second side wall 312; the second movable section 332 is arranged to deform towards the second side wall 312 when the shaped block 723 is in the shaped channel 34.

[0041] Specifically, during production, the first engaging block 32 and the second engaging block 33 are two independent components produced independently of the connecting unit 1, and the receiving groove 31 is formed on the inner wall of the insertion hole 2. When the receiving groove 31 is processed, the first fixing section 321 and the second fixing section 331 are respectively fixed to the lower end of the first side wall 311 and the upper end of the second side wall 312. Preferably, the fixing method is glue fixing. When glue adheres to the first fixing section 321 and the second fixing section 331, the first fixing section 321 and the second fixing section 331 can be simultaneously bonded to the lower end of the first side wall 311, the second side wall 312, and the bottom wall of the receiving groove 31, thereby making the fixation of the first engaging block 32 and the second engaging block 33 relatively firm and not easily loosening during the repeated insertion and extraction of the connecting rod 72. The first movable section 322 and the second movable section 332 are deformable free sections. During the process of inserting or extracting the connecting rod 72 from the insertion hole 2, the first movable section 322 deforms along the direction A as shown in Figure 9 , and the second movable section 332 deforms along the direction B as shown in Figure 9 to cooperate with the entry and exit movements of the shaped block 723 in the shaped channel 34 through deformation. When the shaped block 723 is in the shaped channel 34, the first movable section 322 acts on the first convex block 7231 at the upper end of the shaped block 723 in the opposite direction of the direction A as shown in Figure 9 , and the second movable section 332 acts on the first convex block 7231 at the upper end of the shaped block 723 in the opposite direction of the direction B as shown in Figure 9The second convex block 7232 acting in the opposite direction of the B direction shown acts on the lower end of the special-shaped block 723, thereby clamping the special-shaped block 723 from both sides, preventing the toothbrush handle connection structure from loosening axially, and making the installation more secure.

[0042] Please further refer to Figure 7 , wherein the second fitting block 33 further includes an upper fastening portion 333 and a lower fastening portion 334 disposed on one side facing the special-shaped channel 34; the upper fastening portion 333 is disposed at the upper end of the second movable section 332, and the lower fastening portion 334 is disposed at the lower end of the second movable section 332.

[0043] It can be understood that when the second fitting block 33 is provided with the upper fastening portion 333 and the lower fastening portion 334, it can cooperate with the state of the special-shaped block 723 in the special-shaped channel 34; specifically, the lower fastening portion 334 can abut against the lower end portion of the special-shaped block 723, and the upper fastening portion 333 can abut against the second convex block 7232, thereby further preventing the toothbrush handle connection structure from loosening axially.

[0044] Please continue to refer to Figure 4 、 Figure 7 、 Figure 8 , wherein the jack 2 includes a lower jacking section 21 and an upper jacking section 22 arranged in sequence from bottom to top; the lower jacking section 21 is arranged to cooperate with the lower section of the connecting rod 72; the upper jacking section 22 is arranged to cooperate with the upper section of the connecting rod 72; the special-shaped block fitting unit 3 is arranged in the lower jacking section 21.

[0045] During use, the lower jacking section 21 is used to cooperate with the lower section 722 of the connecting rod and there is a certain frictional force between them, and the upper jacking section 22 is used to cooperate with the upper section 721 of the connecting rod and there is a certain frictional force between them; under the combined action of the multi-segment frictional forces of the lower jacking section 21 and the upper jacking section 22, the connection between the toothbrush handle connection structure and the toothbrush handle 7 is made more firm, and it can also cooperate with the special-shaped block fitting unit 3 to further prevent the toothbrush handle connection structure from loosening axially.

[0046] Please continue to refer to Figure 4 、 Figure 6 、 Figure 8 , which further includes: at least one straight block fitting unit 4, wherein the straight block fitting unit 4 is used to cooperate with the straight block 724.

[0047] During assembly, multiple straight blocks 724 need to be accurately inserted into the block fitting unit 4 to limit the assembly direction of the toothbrush handle connection structure; there is a certain frictional force between the straight block 724 and the block fitting unit 4 to cooperate with the special-shaped block fitting unit 3 to further prevent the toothbrush handle connection structure from loosening axially.

[0048] Please continue to refer to Figures 10-11A toothbrush handle fitting shown, comprising the aforementioned toothbrush handle connection structure, further comprising an oral action part 5, and the movement of the toothbrush handle 7 is transmitted to the oral action part 5 through the toothbrush handle connection structure; the oral action part 5 contacts the oral cavity to exert an action on the oral cavity.

[0049] Specifically, the oral action part 5 is preferably integrally formed with the toothbrush handle connection structure using bamboo material to simplify the processing steps and can omit the assembly steps between the two; the vibration generated by the toothbrush handle is transmitted to the oral action part 5 through the toothbrush handle connection structure and is converted into actions such as vibration and rotation of the oral action part 5 to exert an action on various parts in the user's oral cavity.

[0050] It can be understood that the oral action part 5 can also be independently manufactured using bamboo or other materials. For example, the oral action part 5 is made of metal material to form a massage component and made of rubber material to form a friction component.

[0051] In some embodiments, the oral action part 5 includes at least one of a toothbrush head, a gum massage head, a tongue massage head, and an oral wall massage head to exert an action on different parts in the oral cavity; please refer to Figure 11 , for example, the oral action part 5 can be set as a toothbrush head with bristles thereon. When the vibration generated by the toothbrush handle occurs, the vibration is transmitted to the toothbrush head through the toothbrush handle connection structure and finally acts on the teeth to enable the user to obtain a better effect of cleaning teeth.

[0052] Please continue to refer to Figure 10 、 Figure 11 , which further includes a transition section 6, and the transition section 6 is arranged between the toothbrush handle connection structure and the oral action part 5.

[0053] It can be understood that the oral action part 5 can be set as various specific structures to exert an action on various parts of the oral cavity. When there is a transition section 6 between the toothbrush handle connection structure and the oral action part 5, it can better cooperate with the oral action part 5 to enable the oral action part 5 to extend to a suitable oral area.

[0054] Furthermore, the transition section 6 can make the oral action part 5 extend to a suitable oral area through length control, or the transition section 6 can be set as an arc to reach oral parts such as the upper jaw.

[0055] The above only describes the best embodiments of the present invention, but it cannot be understood as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
