Description

Technical Field

[0001] The utility model belongs to the technical field of massagers, and more specifically, relates to a transmission box of a bath-scrubbing massager. Background Art

[0002] A bath massager is a convenient and practical personal care tool. It usually has soft bristles or a friction surface that can effectively remove dirt and dead skin cells on the skin surface, making the skin cleaner and smoother. It massages the body through vibration or rotation, promotes blood circulation, and relieves muscle fatigue and tension.

[0003] Existing electric bath massagers typically feature a single massage head, directly driven by an internal drive motor. For example, the convenient bath massager disclosed in Chinese Patent Application No. 201120093242.1 utilizes a single rotating wheel to drive abrasive blocks for skin cleansing. However, the limited cleaning capacity of a single abrasive block during rotation makes it difficult to quickly clean the skin. Therefore, in light of these shortcomings, research and improvements were conducted to address existing structures and provide a transmission case for a bath massager with greater practical value.
