Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] As attached Figure 1 , 5 As shown in Figures 7 and 8, this embodiment provides a toothbrush that is easy to assemble, including a toothbrush body 1, a brush head 2, and a pressure frame 3.

[0019] As attached Figure 5 , 7 As shown in Figure 8, the toothbrush body 1 includes an integrally formed brush head 11 and a brush handle 12. The bottom edge of the brush head 11 is provided with multiple grooves 111. Specifically, the multiple grooves 111 are evenly distributed along the outer periphery of the brush head 11.

[0020] As attached Figure 5 As shown, the brush head 2 includes a base plate 21 and bristles 22 distributed on the base plate 21. The base plate 21 serves as the base for the bristles 22 and fixes the bristles 22. The base plate 21 is placed on the top surface of the brush head 11.

[0021] As attached Figure 3, 9 As shown, the bottom outer edge of the pressure frame 3 is integrally formed into a buckle 31. The pressure frame 3 presses down on the base plate 21 and the buckle 31 is engaged with the buckle groove 111. Align the buckle 31 with the buckle groove 111 and press the pressure frame 3 so that the buckle 31 is engaged with the buckle groove 111, thereby making the pressure frame 3 and the brush head 11 clamp the base plate 21, thereby fixing the brush head 2 and fixing it to the toothbrush body 1.

[0022] In this embodiment, the toothbrush body 1 includes an integrally formed brush head 11 and a handle 12. The bottom edge of the brush head 11 is provided with multiple snap-fit ​​grooves 111. The brush head 2 includes a base plate 21 and bristles 22 distributed on the base plate 21. The bottom outer edge of the pressure frame 3 is provided with a buckle 31. First, the base plate 21 of the brush head 2 is placed on the top surface of the brush head 11. The buckle 31 is aligned with the snap-fit ​​grooves 111, and the pressure frame 3 is pressed down. The pressure frame 3 presses down on the base plate 21, and the buckle 31 is engaged with the snap-fit ​​grooves 111, thereby clamping the base plate 21 with the pressure frame 3, thus fixing the brush head 2. The entire assembly process is simple to operate, and since the pressure frame 3 is pressed directly, not much force is required, which facilitates the assembly of the brush head 2.

[0023] Further details are attached. Figure 10-11 As shown, the outer edge of multiple slots 111 is provided with anti-disengagement hooks 1111, and the buckle 31 is engaged with the anti-disengagement hooks 1111. The engagement between the buckle 31 and the anti-disengagement hooks 1111 is a slanted hook-type engagement, which makes the clamping frame 3 and the brush head 11 more tightly engaged under force, avoiding the problem of buckle 31 disengaging due to bending and deformation under force.

[0024] Based on the above plan, as shown in the appendix Figure 5-6 As shown, the top edge of the brush head 11 is provided with multiple positioning notches 112. The positioning notches 112 communicate with the snap grooves 111. The buckle 31 is positioned and engaged with the positioning notches 112, so that before pressing the pressure frame 3, the buckle 31 can be positioned and engaged with the snap grooves 111, and the buckle 31 can be quickly aligned with the snap grooves 111, which is convenient for assembling the toothbrush.

[0025] Further details are attached. Figure 3 , 7 As shown in Figure 8, the bottom inner edge of the pressure frame 3 is integrally formed with a slot 32, and the edge of the base plate 21 is locked in the slot 32, so that the pressure frame 3 can fix the base plate 21 in the vertical and horizontal directions to prevent the brush head 2 from moving.

[0026] When it is necessary to replace brush head 2, see attached Figure 5As shown, both the pressure frame 3 and the base plate 21 have an auxiliary replacement notch 33 integrally formed from top to bottom, located above the buckle 31. Specifically, a tool can be inserted through the auxiliary replacement notch 33 of the pressure frame 3 and the base plate 21, and then inserted into the positioning notch 112 between the buckle 31 and the brush head 11. With a little force, the buckle 31 expands outward in the horizontal direction, disengaging from the buckle groove 111, thereby separating the pressure frame 3, the brush head 2, and the brush head 11 for easy disassembly and replacement of the brush head 2.

[0027] It is worth mentioning that, as shown in the attached document Figure 5 As shown, the top of the brush head 11 is integrally formed with a placement groove 113, and the base plate 21 and the pressure frame 3 are placed in the placement groove 113, thereby reducing the thickness of the brush head 11 in the vertical direction and making the toothbrush smaller.

[0028] In some embodiments, as shown in the appendix Figure 1 , 5 As shown, the toothbrush also includes a soft rubber protective sleeve 4, which comprises an integrally molded head cover 41 and a handle cover 42. The head cover 41 covers the brush head 11 and the pressure frame 3, and the handle cover 42 at least partially covers the brush handle 12. Specifically, the soft rubber protective sleeve 4 is made of soft rubber, which acts as a buffer during brushing, reducing the risk of abrasions or scratches caused by direct contact between the brush head 11 and the gums.

[0029] Based on the above, as shown in the appendix Figure 5-6 As shown, the edge of the brush head 11 is provided with multiple positioning grooves 114, and the inner wall of the head cover 41 is formed by injection molding with multiple positioning blocks 411 that cooperate with the positioning grooves 114. The positioning blocks 411 cooperate with the positioning grooves 114 to reduce the positional offset between the head cover 41 and the brush head 11.

[0030] As an improvement to the above embodiments, see the appendix. Figure 4-8 As shown, the brush head 11 has multiple through holes 115 extending from top to bottom along its edge. These through holes 115 are evenly distributed along the edge of the brush head 11 and communicate with the positioning groove 114. (See attached image.) Figure 4 As shown, the inner wall of the head cover 41 is formed with multiple connecting posts 412 that mate with the through holes 115. The connecting posts 412 are evenly distributed along the inner wall of the head cover 41. The connecting posts 412 are integrally formed and connected with the positioning blocks 411. The connecting posts 412, the positioning blocks 411 and the inner wall of the head cover 41 are integrally connected to form a locking ring 413. The locking ring 413 can lock the brush head 11, so that the relative position of the head cover 41 and the brush head 11 remains unchanged, preventing the head cover 41 from detaching from the brush head 11, thereby making the soft rubber protective cover 4 permanently fitted on the toothbrush body 1.

[0031] Additionally, as attached Figure 4-6As shown, the top of the connecting post 412 is provided with a conical protrusion 4121. The conical protrusion 4121 is made of the same soft rubber material as the connecting post 412, the positioning block 411, and the soft rubber protective sleeve 4. The conical protrusion 4121 is offset from the outer periphery of the brush head 11 to the middle of the brush head 11. After assembling the base plate 21 and the pressure frame 3, the base plate 21 presses the conical protrusion 4121 to keep the base plate 21 and the brush head 11 in a tensile state, so as to prevent the base plate 21 from loosening.

[0032] It is worth mentioning that, as shown in the attached document Figure 1-2 As shown, a foam-blocking wall 421 is integrally formed on the end of the handle sleeve 42 away from the head sleeve 41. During brushing, toothpaste foam and saliva flow down the handle sleeve 42 to the foam-blocking wall 421 and drip down the foam-blocking wall 421, preventing toothpaste foam and saliva from flowing back onto the hand.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
