Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0027] like Figure 1-9 A toothbrush testing device 100 includes a clamping structure 1, a testing structure 2, and a driving structure. The clamping structure 1 includes a clamping frame 11 and a clamping assembly 12 mounted on the clamping frame 11. The clamping assembly 12 is used to clamp the toothbrush. The driving structure is connected to the testing structure 2 and is used to drive the testing structure 2 to move in the front-back direction and / or left-right direction. The testing structure 2 includes a pressure detector 21 and a tooth simulation assembly 22. The tooth simulation assembly 22 is mounted on the pressure detector 21. The pressure detector 21 is used to acquire the pressure value applied by the toothbrush to the tooth simulation assembly 22 when the testing structure 2 moves in the front-back direction or left-right direction.

[0028] This invention proposes a toothbrush testing device, in which the toothbrush is held by the clamp assembly 12, and the tooth simulation assembly 22 is moved in the front-back or left-right direction by the drive assembly. The toothbrush acts on the moving tooth simulation assembly 22, and the pressure applied by the toothbrush to the tooth simulation assembly 22 is detected by the pressure detector 21.

[0029] The pressure applied by the toothbrush to the tooth simulation component 22 can be obtained and tested through the toothbrush testing device, which can prevent the pressure applied by the toothbrush to the teeth from exceeding the preset maximum value and avoid the situation where the toothbrush does not meet people's needs due to excessive pressure.

[0030] The test structure 2 also includes a moving stage 23, the pressure detector 21 is mounted on the moving stage 23, and the drive structure is connected to the moving stage 23 to drive the moving stage 23 to move.

[0031] In this embodiment, the pressure detector 21 is mounted on the moving stage 23, and the tooth simulation component 22 is mounted on the pressure detector 21. The movement of the moving stage 23 drives the movement of the tooth simulation component 22.

[0032] In this embodiment, the driving structure can drive the mobile stage 23 to move in the forward and backward and left and right directions.

[0033] In this embodiment, the pressure detector 21 is fixedly mounted on the moving stage 23. That is, the pressure detector 21 and the moving stage 23 cannot be separated.

[0034] In some other embodiments, the pressure detector 21 and the moving stage 23 are detachably connected. The moving stage 23 has a first limiting post and a second limiting post, which limit the pressure detector 21. The first limiting post has a first mounting hole and / or the second limiting post has a second mounting hole. The pressure detector 21 has a third mounting hole. A first screw can pass through the first mounting hole and the third mounting hole to fix the pressure detector 21 to the first limiting post, and / or a second screw can pass through the second mounting hole and the third mounting hole to fix the pressure detector 21 to the second limiting post.

[0035] The mobile station 23 includes a first mounting platform 230, a first mobile station 231, a second mounting platform 233, and a second mobile station 232, with the first mobile station 231 mounted on the second mobile station 232.

The front edge of the first movable stage 231 extends downward to form an extended edge, and a tooth pattern 2311 is formed at the extended edge. The driving structure includes a first motor 31 and a gear 32. The gear 32 is mounted on the first motor 31 so that the rotation of the first motor 31 drives the gear 32 to rotate. The gear 32 engages with the tooth pattern of the extended edge so that the rotation of the gear 32 drives the first movable stage 231 to slide to the left or right.

[0037] The second mounting platform 233 is mounted on the first movable platform 231. The drive structure further includes a second motor 34, which is connected to the forward and backward moving lead screw 33 to drive the lead screw 33 to rotate. A connecting block 331 is provided on the forward and backward moving lead screw 33, and the connecting block 331 is connected to the second movable platform 232. The rotation of the forward and backward moving lead screw 33 drives the connecting block 331 to move forward and backward, further driving the second movable platform 232 to move forward and backward. The pressure detector 21 is fixedly mounted on the second movable platform 232.

[0038] In some embodiments, the second motor is provided with a pulley at its bottom.

[0039] The tooth simulation component 22 includes a base 221 and a tooth model 222. An installation box is formed on the base 221, and an installation cavity 2211 is formed inside the installation box. The tooth model 222 is installed in the installation cavity 2211.

[0041] In some embodiments, a downwardly facing engagement groove is formed at the base 221, which engages with the pressure detector 21 to connect the base 221 to the pressure detector 21.

[0042] The dental mold 222 is a tooth simulation mold. The dental mold 222 is installed in the mounting cavity 2211 and can also be removed from the mounting cavity 2211. Different dental molds 222 can be placed in the mounting cavity 2211.

[0043] In this embodiment, a groove 2213 is formed in the mounting box near the mounting cavity 2211. When taking the dental mold 222 out of the box, the groove provides space for the fingers to avoid obstructing movement, making it easier to take the dental mold 222 out of the box.

[0044] The dental model 222 includes a dental model body 2221 and a plurality of protruding blocks 2222 extending from the upper surface of the dental model body 2221. The protrusion height of each protruding block 2222 is 0.2-0.8 mm, and the gap between adjacent protruding blocks is 1-4 mm. Different sizes of dental models can be selected to suit different groups of people, such as children and adults whose teeth are different sizes, thus enabling toothbrush testing suitable for different groups. The gaps between the protruding blocks simulate the gaps between teeth.

[0045] In this embodiment, the protrusion height of the protrusion block is 0.5mm, and the gap between the protrusion blocks is 2mm.

[0046] The protrusion 2222 has a square cross-section, and the side length of the protrusion 2222 is 3-6mm. In this embodiment, the side length of the protrusion is 4mm.

[0049] In this embodiment, the first lead screw assembly includes a first height adjusting lead screw and a second height adjusting lead screw. The clamping assembly 12 is connected to both the first and second height adjusting lead screws to adjust the height of the clamping assembly 12 by rotating the first and second height adjusting lead screws. Since the height of the tooth simulation assembly 22 remains constant, the distance between the clamping assembly 12 and the tooth simulation assembly 22 is adjusted by the first and second height adjusting lead screws.

[0050] The clamp assembly 12 includes a clamp body 121, a clamping member 122 and a second lead screw 123. One end of the second lead screw 123 is connected to the clamp body 121 and the other end is connected to the clamping member 122, forming a clamping cavity 124 between the clamp body 121 and the clamping member 122.

One end of the first distance adjusting lead screw and the second distance adjusting lead screw are connected to the clamp body 121, and the clamping member 122 is installed on the first adjusting lead screw and the second adjusting lead screw so as to adjust the distance between the clamping member 122 and the clamping part by rotating the first adjusting lead screw and the second adjusting lead screw, that is, to adjust the size of the clamping cavity 124.

[0053] In this embodiment, the cross-section of the clamping cavity 124 is narrower at the top and wider at the bottom, effectively clamping the toothbrush.

[0054] In some embodiments, the clamping cavity 124 has a trapezoidal cross-section.
