Description

Technical field:

[0001] The utility model relates to the technical field of teeth cleaning tools, in particular to a teeth cleaner with an illumination function. Background technology:

[0002] As people pay more and more attention to oral health, a variety of teeth cleaning tools have appeared on the market. Toothbrush can be used specifically to remove stains such as tartar and plaque. It generally includes a handle that is easy for users to operate and a working head that actually cleans the teeth. The existing teeth cleaning process is generally completed by medical personnel, which will cause some disadvantages. For example, toothbrush is generally used in conjunction with proprietary instruments, resulting in a large space occupied by the entire device. During the teeth cleaning process, medical personnel keep their heads down for a long time and have to observe the cleaning situation at all times, causing physical discomfort, such as fatigue. The individual differences in the observation of medical personnel lead to inadequate cleaning. In addition, people need to go to medical institutions for teeth cleaning, which wastes time.

[0003] To address these issues, home-use dental cleaning devices have emerged. Ultrasonic tooth cleaners utilize the high frequency and energy of ultrasound to propel the tooth cleaner, loosening tiny tartar deposits and removing plaque and other impurities, leaving teeth clean and maintaining oral health.

[0004] The Chinese utility model patent with authorization announcement number CN216724831U discloses a tooth cleaner handle, which includes: a top cover, a top cover bracket is provided on the inner side of the top cover; a light board, the light board is arranged at the upper end of the top cover bracket; a waterproof light guide ring, the waterproof light guide ring is sleeved on the front end of the light board; and a transducer is arranged in the top cover bracket; the light board and the waterproof light guide ring are both hollow annular structures, the amplitude adjustment shaft at the front end of the transducer extends from the center of the light board and the waterproof light guide ring, and the inner side of the waterproof light guide ring is interference fit with the amplitude adjustment shaft at the front end of the transducer.

The assembly structure is extremely complicated and its installation is not convenient. Moreover, an assembly gap is formed between the front shell and the rear shell, and an assembly gap is also formed between the top cover bracket and the upper part of the handle holding portion, so that the sealing effect of the toothbrush handle assembly structure is not good and the waterproof effect needs to be improved.
