[0027] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0028] Embodiment 1:

[0029] like Figure 1-3 As shown, a tooth brush handle comprises a handle 1, a mounting rod 7 is fixed on the top of the handle 1, a brush handle 2 is fixed on the top of the handle 1 through the mounting rod 7, when the brush handle 2 is fixed to the handle 1, the mounting rod 7 can be inserted into the inside of the brush handle 2, that is, into the first plug hole 10 described below, to achieve interference fit, so as to complete the installation of the brush handle 2 on the handle 1, and a fastening assembly is arranged inside the brush handle 2, and the fastening assembly is used to strengthen the fastness between the mounting rod 7 and the brush handle 2;

[0030] A seal is also provided between the brush handle 2 and the handle 1, and the seal is used to seal the handle 1 and the brush handle 2 after installation;

[0031] A mounting head 3 is fixed on the top of the brush handle 2. The mounting head 3 can be arranged horizontally or tilted on the brush handle 2. In short, the purpose of its arrangement is to make it more convenient for the user to take the handle 1 and brush the gaps between teeth. At least one plug-in rod 16 is arranged at the end of the mounting head 3.

[0032] See attached Figure 3The fastening assembly includes an extrusion block 8 fixed to the inner side of the brush handle 2, and an extrusion ring 9 is fixed to the inner side of the plurality of extrusion blocks 8. By setting the extrusion block 8, the extrusion block 8 does not need to be fully surrounded on the brush handle 2, and the extrusion ring 9 can be wrapped, which saves materials and does not lose the effect. The extrusion block 8 and the extrusion ring 9 can be made of flexible materials such as rubber, and the first plug hole 10 corresponding to the mounting rod 7 is arranged inside the extrusion ring 9;

[0033] When the mounting rod 7 is inserted into the first plug hole 10, the mounting rod 7 squeezes the extrusion ring 9, and the extrusion ring 9 squeezes the extrusion block 8, so that the extrusion block 8 and the extrusion ring 9 in turn squeeze the mounting rod 7, so that the mounting rod 7 is inserted into the first plug hole 10 with an interference fit, thereby ensuring the installation effect of the handle 1 and the brush handle 2;

[0034] Furthermore, the handle 1 can be replaced with other components that can vibrate, such as a motor, so as to drive the brush handle 2 to vibrate, thereby improving the effect of the user when brushing between teeth.

[0035] See attached Figure 2 The sealing member is a sealing ring gasket 4, which is made of a flexible material, such as rubber, etc. The sealing ring gasket 4 is arranged between the brush handle 2 and the handle 1, and sealing teeth 5 are arranged on the top and bottom of the sealing ring gasket 4, and a first sealing groove 6 and a second sealing groove 20 corresponding to the sealing teeth 5 are respectively arranged inside the brush handle 2 and inside the handle 1.

[0036] When the handle 1 and the brush handle 2 are installed, the sealing ring gasket 4 can be clamped in the middle, and the sealing teeth 5 set at the top and bottom of the sealing ring gasket 4 can make the brush handle 2 and the handle 1 combined, so that the sealing effect is better, and the height of the sealing teeth 5 is greater than the height of the first sealing groove 6 and the height of the second sealing groove 20, so that when the handle 1 and the brush handle 2 are combined, the sealing teeth 5 on the sealing ring gasket 4 have a compression effect, thereby making the sealing effect between the handle 1 and the brush handle 2 more excellent.

[0037] Embodiment 2:

[0038] Please refer to the attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, this embodiment, based on the first embodiment, proposes a replacement head matching the interdental brush handle, which includes a brush head 11, and a clamping structure is provided inside the brush head 11, and the clamping structure is used to clamp the brush head 11 with the plug-in rod 16;

[0039] See attached Figure 5The clamping structure includes a central fixing column 18 fixed at the center of the brush head 11, and a pressing pad 19 is also provided inside the brush head 11, and the pressing pad 19 wraps the central fixing column 18, and a second plug hole 17 plugged with the plug rod 16 is provided at one end inside the pressing pad 19;

[0040] When installing the brush head 11, the plug-in rod 16 can be aligned with the second plug-in hole 17, and then the brush head 11 can be moved so that the plug-in rod 16 is inserted into the inside of the second plug-in hole 17. The squeezing pad 19 is set so that the plug-in rod 16 and the second plug-in hole 17 are interference fit, and the squeezing pad 19 is set so that it will not be compressed too much toward the center of the brush head 11, thereby ensuring the tightness of the plug-in rod 16 inserted into the second plug-in hole 17. When replacing the brush head 11, the brush head 11 can be pulled out and replaced directly.

[0041] A plurality of mounting grooves 12 are disposed on the outer side of the brush head 11 , and a tooth brushing assembly is disposed inside each mounting groove 12 .

[0042] See attached Figure 4 Furthermore, the toothbrush assembly includes a connection pad 13 arranged inside the mounting groove 12, a plurality of bristles 14 are fixed to the top of the connection pad 13, a fixing strip 15 is also fixed to the inner side of the mounting groove 12, and the fixing strip 15 is used to limit the connection pad 13.

[0043] When the manufacturer installs the connecting pad 13, the connecting pad 13 can be placed into the mounting groove 12, and the fixing strip 15 can also be placed into the mounting groove 12. The connecting pad 13 is restricted and pressed by the fixing strip 15, so that the connecting pad 13 is fixed inside the mounting groove 12. The fixing strip 15 and the brush head 11 can be fixed by gluing or welding.

[0044] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
