This lathering process is slow and the lathering effect is poor. To address this lathering issue, some existing bath brushes have been developed with built-in lathering functions. For example, Chinese utility model patent CN202321134429.0, published on September 12, 2023, discloses a foam bath brush, comprising: a brush with a mounting surface and a bristle surface, the bristle surface having a plurality of bristles, and a through-hole on the brush connecting the bristle surface and the mounting surface; the brush being connected to a handle assembly via the mounting surface, the handle assembly having a mounting cavity and a connection channel inside, the connection channel communicating with the through-hole; a foaming device installed in the mounting cavity, the foam outlet of the foaming device connecting with the connection channel, the foaming device being used to convert the liquid contained within it into foam and output it to the bristle surface along the connection channel and the through-hole; pressing the foaming device converts the shower gel into foam, the foam being output to the bristle surface along the connection channel and the through-hole. In the above solution, air is manually forced into the bottle to form foam, which is inconvenient to use, and this structure cannot be used in an electric bath brush. Utility Model Content

The foaming mechanism 4 includes a foaming chamber 41, an inlet / outlet channel 42 communicating with the foaming chamber 41, and an aeration component 43 for adding gas to the foaming chamber 41. The drive motor 11 drives the aeration component 43. External water and foaming liquid enter the foaming chamber 41 through the inlet / outlet channel 42. The aeration component 43 adds gas to the foaming chamber 41, causing the gas to mix with the water and foaming liquid to generate bubbles. The bubbles are discharged through the inlet / outlet channel 42 and accumulate on the bristles 32. This utility model is an electric bath brush; the drive motor 11 can drive the bath brush head 3 to rotate, thereby improving the scrubbing effect. Of course, in other variations, the bath brush head 3 can also remain stationary, with the drive motor 11 serving as the driving mechanism for the foaming mechanism 4. This invention incorporates the foaming mechanism 4 within the brush disc 31, which rotates together with the brush disc 31, thus making the foaming mechanism 4 suitable for an electric bath brush. In this invention, the air-filling component 43 is driven by the drive motor 11, allowing for continuous and uniform gas filling, resulting in even and sustained foam, better foaming effect, and greater ease of use.
