[0032] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0033] like Figure 1 As shown, an integrated toothpaste squeezing toothbrush with replaceable toothpaste inside comprises a toothbrush head 1, a brush handle 2 and a tail plug 3. The tail plug 3 is used to connect the toothbrush head 1 and the brush handle 2, and the tail plug 3 is detachably connected to the brush handle 2.

[0034] Such as 1. Figure 3 and Figure 4 As shown, the toothbrush head 1 comprises a brush head 11 and a brush tube 12, one end of the brush tube 12 is connected to the brush head 11, and the other end is open and connected to the tail plug 3. The brush tube 12 has a toothpaste passage, bristles 111 and a mounting groove 113 are provided on the toothbrush head 1, and a toothpaste outlet 112 connected to the toothpaste passage is provided on the bottom wall of the mounting groove 113.

[0035] like Figure 3-Figure 6As shown, a rubber pad 13 is clamped in the mounting groove 113, and a paste outlet 131 and a plurality of rubber brush teeth 133 are provided on the rubber pad 13. The rubber brush teeth 133 can also be called rubber bristles, and nylon bristles can be used for the bristles 111. When the rubber pad 13 is installed in the mounting groove 113, the paste outlet 131 is inserted into the paste outlet 112, and a through hole 132 is provided on the paste outlet 131. The paste entering the toothpaste channel is squeezed out through the through hole 132. The rubber brush teeth 133 and the bristles 111 surround the outer side of the paste outlet 131, so that the rubber brush teeth 133 and the bristles 111 surround the through hole 132, so that when the paste is squeezed out of the through hole 132, it is located between the rubber brush teeth 133 and the bristles 111, which is convenient for the effective use of toothpaste and makes the through hole 132 not easy to be contaminated. A plurality of mounting recessed holes 114 are also provided on the bottom wall of the mounting groove 113, and a plurality of clamping posts 134 corresponding to the mounting recessed holes 114 are provided on the back of the rubber pad 13. When the clamping posts 134 are installed in the mounting recessed holes 114, they are in an extruded state, so that the clamping posts 134 and the mounting recessed holes 114 are tightly connected, further improving the stability of the rubber pad 13 installed in the mounting groove 113. When the clamping posts 134 are installed in the mounting recessed holes 114, the paste outlet 131 is inserted into the paste outlet 112, and the rubber pad 13 is clamped in the mounting groove 113.

[0036] like Figure 5 and Figure 6 As shown, the through hole 132 on the paste outlet 131 is cross-shaped, including an outer hole end and an inner hole end, and the inner hole end is an end inserted into the paste outlet 112. The through hole 132 gradually decreases from the inner hole end to the outer hole end, and the outer hole end of the through hole 132 is closed when it is naturally not subject to external force. Such a setting not only allows the paste to be squeezed out of the through hole 132 normally, but also allows the through hole 132 to be closed as a whole when the utility model is not in use, which can effectively protect the toothpaste in the toothpaste channel of the brush tube part 12 and effectively prevent the toothpaste in the toothpaste channel from deteriorating.

[0037] like Figure 1 , Figure 3 and Fig. 9 As shown, an upper annular connecting platform 31 is provided at the upper end of the tail plug 3, and an end of the toothpaste passage of the brush tube part 12 away from the brush head part 11 has a sleeve opening adapted to the upper annular connecting platform 31, and the brush tube part 12 is sleeved on the upper annular connecting platform 31 of the tail plug 3. The brush tube part 12 and the tail plug 3 can be welded into an integral part by ultrasonic welding.

The brush handle 2 has a resilient soft rubber pressing portion 21 for pressing the toothpaste 4 placed in the toothpaste placement cavity. The lower end of the tail plug 3 is provided with a lower annular connecting platform 32, and the upper end of the brush handle 2 is sleeved on the lower annular connecting platform 32 of the tail plug 3. In order to improve the connection stability between the brush handle 2 and the tail plug 3, the brush handle 2 is connected to the lower annular connecting platform 32 by snapping or screwing.

[0039] like Figure 2 and Fig. 9 As shown, the tail plug 3 is provided with a through hole 301, which connects the toothpaste passage and the toothpaste placement cavity. The through hole 301 has a mounting structure adapted to the toothpaste head, and is used to install the toothpaste 4. For example, the inner wall of the through hole 301 is provided with an internal thread structure adapted to the toothpaste head, and the toothpaste head of the toothpaste 4 is threadedly installed in the through hole 301.

[0040] The working principle of the utility model is as follows: the toothpaste 4 is screwed and installed in the through hole 301 of the tail plug 3, and then the brush handle 2 is installed on the tail plug 3. The soft rubber pressing part 21 is pressed, and the toothpaste 4 is pressed by the soft rubber pressing part 21, and the paste in the toothpaste 4 first enters the toothpaste channel of the brush tube part 12, and then enters the through hole 132. After the paste is squeezed out of the through hole 132, the soft rubber pressing part 21 is released to brush teeth.

[0041] In summary, the utility model can directly install the toothpaste 4 on the tail plug 3 for use without changing the conventional toothpaste 4 packaging, and does not need to add toothpaste to the toothpaste storage structure, and does not cause the problem of toothpaste quality being affected by contact with air when adding toothpaste. It is not only more convenient to use, but also safer. The toothbrush head 1 and the brush handle 2 of the utility model can be replaced, which has the advantage of good replaceability, and by replacing the brush handle 2 with different styles, patterns, and colors, the theme form can be changed, which can have different emotional experiences and help improve the user experience.
