Technical Field

[0001] This utility model relates to the field of electric shaver technology, and in particular to an adjustable electric shaver head. Background Technology

[0002] An electric shaver is a shaving tool powered by electricity. It is a personal care appliance primarily used for removing facial hair. Compared to traditional manual shavers, electric shavers offer a more convenient and comfortable shaving experience. The shaver head is one of the core components of an electric shaver, responsible for directly contacting the skin and cutting the hair.

[0003] Existing razor heads are not convenient for adjusting the distance between the blade and the beard, making it inconvenient to trim the length of the beard according to personal preference. This has certain limitations in use and reduces the practicality of the device. Therefore, we propose an adjustable electric razor head to solve this problem. Utility Model Content
