Description

Technical Field

[0001] The utility model relates to the technical field of interdental brushes, in particular to a built-in storage type interdental brush head. Background Art

[0002] Interdental brushes are mainly used as auxiliary cleaning tools for cleaning gaps between teeth that are difficult to clean with a toothbrush. There are wire-type interdental brushes using a wire as a shaft material and wireless interdental brushes using a synthetic resin material as a shaft material.

[0003] However, in the prior art, the brush head of the interdental brush is generally a fixed structure. After use, the brush head is directly exposed to the outside, which is easy to be infected with bacteria, which is not conducive to ensuring the cleanliness of the interdental brush. At the same time, it is not convenient to replace the brush head when it is damaged. For this reason, we propose a built-in storage type interdental brush head. Utility Model Content

[0021] The following is combined with Figure 1-4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0022] Example 1

[0023] like Figure 1-4As shown, the utility model provides a built-in storage type interdental brush head, including a hollow brush head rod 1, a sealing ring 15 is fixedly installed at the end of the brush head rod 1, and a card groove corresponding to the sealing ring 15 is opened on the outer wall of the connecting tube 2. The sealing ring 15 can be tightly matched with the card groove of the connecting tube 2 to prevent water from entering the gap between the connecting tube 2 and the brush head rod 1. The inner wall of the brush head rod 1 is slidably matched with a hollow connecting tube 2, and the connecting tube 2 is connected to the brush head rod 1 through a sliding mechanism. The sliding mechanism includes a sliding groove laterally opened on the inner wall of the brush head rod 1, and a slider is slidably installed on the inner wall of the sliding groove. The slider is fixedly connected to the outer wall of the connecting tube 2. When the sliding groove and the slider are set, the connection between the connecting tube 2 and the brush head rod 1 is connected, and the connecting tube 2 is limited so that the connecting tube 2 can only move laterally and cannot be deflected, thereby ensuring the function of the device is realized. The connecting tube 2 is connected to a movement control mechanism, and a connecting block 3 is fixedly installed at the end of the connecting tube 2. A detachable head 4 is movably embedded in the connecting block 3, and a brush head 5 is fixedly installed on the detachable head 4. The outer wall of the connecting block 6 is fixedly installed, and the inner wall of the connecting block 3 is provided with a groove 7 that matches the connecting block 6. The groove 7 is provided with a built-in groove 8. The inner wall of the built-in groove 8 is fixedly provided with a clamping block 10 through a spring 9. The clamping block 10 is movably embedded in the outer wall of the connecting block 6. The clamping block 10 is connected with a clamping cancellation mechanism. The clamping cancellation mechanism includes a control ring 13 rotatably installed on the outer wall of the connecting block. The control ring 13 is fixedly connected to the clamping block 10 through a steel wire 14 that movably penetrates the connecting block 3. The outer wall of the control ring 13 is provided with continuous tooth grooves. The rotating control ring 13 can indirectly drive the clamping block 10 to move through the transmission of the steel wire 14, so that the clamping block 10 overcomes the force of the spring 9 and retracts into the built-in groove 8, and the clamping is quickly cancelled. The device provides an installation basis for the brush head 5 through the movable connecting tube 2. The small motor 11 can indirectly drive the brush head 5 to move. After use, the brush head 5 can be retracted into the brush head 1 to protect the brush head 5 and reduce pollution, and the brush head 5 can be quickly disassembled and replaced.

[0024] Example 2

[0025] like Figure 1-4 As shown, the mobile control mechanism includes a small motor 11 which is laterally fixedly installed in the brush head rod 1, and the output shaft of the small motor 11 is laterally fixedly installed with a screw 12 which threads through the connecting tube 2, and the end of the screw 12 is fixedly installed with a limit block arranged in the connecting tube 2. The limit block is used to limit the connecting tube to prevent the connecting tube 2 from separating from the screw 12. The small motor 11 adopts a servo motor which can be rotated forward and reversely. The small motor 11 drives the screw 12 to rotate forward, and the screw 12 drives the connecting tube 2 to move outward, pushing the brush head 5 to the outside of the brush head rod 1, and the small motor 11 drives the screw 12 to rotate in the opposite direction, and the screw 12 drives the connecting tube 2 to move in the box, bringing the brush head 5 back to the brush head rod 1.

[0026] Working principle:

[0027] During use, the brush head rod 1 is docked with the external control rod, and the small motor 11 is controlled to drive the screw 12 to rotate forward. The connecting tube 2 moves toward the outside of the brush head rod 2 under the drive of the screw 12, and the connecting tube 2 drives the brush head 5 to move to the outside of the brush head rod 1 until the limit block contacts the inner wall of the connecting tube 2. After use, the small motor 11 can be controlled to rotate in the opposite direction to reset the brush head 5 back to the brush head rod 1. When replacing the brush head 5, first control the small motor 11 to send the brush head 5 to the outside of the brush head rod 1, and then rotate the control ring 13. The control ring 13 pulls the clamping block 10 back to the built-in groove 8 through the transmission of the steel wire 14 to cancel the clamping. At this time, the brush head 5 can be pulled out and replaced with a new brush head 5, and then the control ring 13 is released, and the spring 9 pushes the clamping block 10 to reset, fixes the connecting block 6, and completes the replacement.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
