Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to an electric toothbrush with a vibration rod having a built-in vibration module and a detachable brush part. Background Art

[0002] Since electric toothbrushes generate their own power, they are easy to use, labor-saving, and have good cleaning power, and are loved by many users. The existing electric toothbrushes mainly include a handheld body and a toothbrush head connected to the front end of the handheld body in terms of structural design. The handheld body has a built-in vibrator, which is connected to the toothbrush head through a power output shaft on the vibrator. The toothbrush head mainly includes a connecting rod and a brush part arranged at the front end of the connecting rod. The connecting rod is connected to the power output shaft of the vibrator. The connecting rod serves as a transition to increase the swing amplitude of the front end. By vibrating the connecting rod, a larger vibration can be generated on the brush part to achieve an electric brushing operation. It can instantly decompose toothpaste into fine foam and deeply clean the gaps between teeth. At the same time, the bristles can promote blood circulation in the oral cavity and have a good massage effect on the gum tissue.

[0003] The brush part needs to be replaced after being used for a period of time, and the existing toothbrush head is generally an integrated structural design, and the toothbrush head and the power output shaft on the vibrator are set as a detachable structure. The toothbrush head is generally inserted into the power output shaft by an interference fit method. When the brush part needs to be replaced, the entire toothbrush head needs to be replaced, and the replacement cost is relatively high. In this regard, the prior art proposes a detachable electric toothbrush as described in the utility model patent authorization announcement number CN208756213U. By setting the brush part as a detachable and replaceable structure, the inconvenience of replacing the entire toothbrush head of the electric toothbrush in the prior art is effectively solved. It is easy to disassemble and install, saving time, effort and cost. However, after the brush part is set as a detachable mechanism, its connecting rod only plays a transitional role. If a vibration module can be set in the connecting rod, it will be able to achieve a more efficient vibration effect. In this regard, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content
