Description

Technical Field

[0001] This utility model relates to the field of electric toothbrush technology, specifically to an electric toothbrush that facilitates quick brush head replacement. Background Technology

[0002] An electric toothbrush is a modern oral hygiene tool that uses electricity to drive the brush head for automatic or semi-automatic brushing. Compared with traditional manual toothbrushes, electric toothbrushes have higher cleaning efficiency and a more comfortable user experience. They are usually equipped with high-speed rotating or vibrating brush heads that can reach deep into hard-to-clean areas such as between teeth and along the gum line, effectively removing plaque and food debris and reducing the occurrence of oral diseases. At the same time, the brush heads of electric toothbrushes are mostly made of soft materials that can gently protect teeth and gums and avoid damage to oral tissues during brushing.

[0003] Existing electric toothbrush heads are connected to the toothbrush body using a snap-fit ​​method. To prevent the brush head from being thrown off during high-frequency vibration, the snap-fit ​​interface is very tight. This means that replacing the brush head requires forceful insertion and removal, which is very laborious. Therefore, there is a need for electric toothbrushes that allow for quick and easy brush head replacement to meet people's needs. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-7 This utility model provides a technical solution: an electric toothbrush that facilitates quick brush head replacement, including an electric toothbrush body 1; in order to solve the problem of the difficulty in removing and replacing the brush head, the electric toothbrush body 1 is provided with a toothbrush body 2, a connector 21 is installed on the top of the toothbrush body 2, a toothbrush head 3 is installed on the connector 21, a connecting cavity 31 is opened in the toothbrush head 3, a connecting port 32 is opened in the connecting cavity 31, the connector 21 is installed in the connecting port 32, and an opening and closing mechanism 4 and a locking mechanism 5 are provided on the toothbrush head 3. Through the opening and closing mechanism 4 and the locking mechanism 5, the flip cover 41 can be quickly opened, making it convenient to separate the toothbrush head 3 from the toothbrush body 2;

[0026] To facilitate the removal of the toothbrush head 3 from the toothbrush body 2, the opening and closing mechanism 4 includes a flip cover 41. The flip cover 41 is rotatably mounted on the toothbrush head 3, and a flip cover groove 42 is formed on the toothbrush head 3. The flip cover 41 is rotatably mounted in the flip cover groove 42. A pressing block 43 is installed on one side of the flip cover 41, and the pressing block 43 presses against the outer surface of the connector 21. A rotating shaft 44 is installed in the flip cover groove 42, and a rotating shaft hole 45 is formed on the flip cover 41. The rotating shaft 44 is rotatably mounted in the rotating shaft hole 45, and a torsion spring 46 is installed in the rotating shaft 44. One end of the torsion spring 46 is mounted on the rotating shaft 44, and the other end of the torsion spring 46 is mounted on the inner wall of the rotating shaft hole 45. When installing the toothbrush head 3, the locking slider 51 is moved, causing the locking slider 51 to slide in the slider groove 52 and compress the return spring 54, thus locking the slider 51. 1. The top of the flip cover 41 is disengaged from the locking hole 53 at the bottom. Under the action of the torsion spring 46 in the pivot hole 45, the flip cover 41 is popped out from the flip cover groove 42. The connector 21 at the top of the toothbrush body 2 is inserted into the connector 32 in the connector cavity 31, so that the protrusion on the connector 21 is aligned with the recess in the connector 32. The flip cover 41 is pressed back into the flip cover groove 42, so that the pressing block 43 on the inside of the flip cover 41 presses against the side of the connector 21. The locking slider 51 is inserted again into the locking hole 53 at the bottom of the flip cover 41 to lock and fix the flip cover 41. When it is necessary to remove the toothbrush head 3, the locking slider 51 is moved again to make the flip cover 41 pop out of the flip cover groove 42. At this time, the pressing block 43 is separated from the connector 21, so that the connector 21 can be removed from the connector 32, and the toothbrush head 3 is separated from the toothbrush body 2.

[0027] Example 2: As Figure 5 and 7 To lock and fix the flip cover 41, the locking mechanism 5 includes a locking slider 51. The toothbrush head 3 has a slider groove 52. The flip cover 41 has a locking opening 53 at the bottom. The locking slider 51 is adapted to the locking opening 53. A return spring 54 is installed in the slider groove 52. One end of the return spring 54 is installed on the locking slider 51, and the other end of the return spring 54 is installed on the inner wall of the slider groove 52. The slider groove 52 is connected to the flip cover groove 42. One end of the locking slider 51 is engaged in the locking opening 53, and the other end of the locking slider 51 is slidably installed in the slider groove 52. The direction of the locking slider 51 is perpendicular to the vibration direction of the toothbrush head 3 to prevent the locking mechanism 5 from loosening when the toothbrush head 3 vibrates. The remaining features are the same as in Embodiment 1.

[0028] The working principle is as follows: When installing the toothbrush head 3, the locking slider 51 is moved, causing it to slide within the slider groove 52 and compress the return spring 54. This disengages the top of the locking slider 51 from the locking opening 53 at the bottom of the flip cover 41. Under the action of the torsion spring 46 within the pivot hole 45, the flip cover 41 pops out from the flip cover groove 42. The connector 21 at the top of the toothbrush body 2 is then inserted into the connector opening 32 within the connector cavity 31, aligning the protrusion on the connector 21 with the recess in the connector opening 32. The flip cover is then opened. The flip cover 41 is pressed back into the flip cover groove 42, so that the pressing block 43 on the inside of the flip cover 41 presses against the side of the connector 21. The locking slider 51 is inserted into the locking hole 53 at the bottom of the flip cover 41 again to lock the flip cover 41. When it is necessary to remove the toothbrush head 3, the locking slider 51 is moved again to make the flip cover 41 pop out of the flip cover groove 42. At this time, the pressing block 43 separates from the connector 21, so that the connector 21 can be removed from the connector hole 32, and the toothbrush head 3 is separated from the toothbrush body 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
