Description

Technical Field

[0001] The utility model relates to the technical field of scalp medicine applicators, in particular to a micro-current scalp massage liquid-conducting comb. Background Art

[0002] At present, some liquid-conducting combs with hair care functions not only have ordinary hair combing functions, but also can apply care liquid to the hair or scalp while combing the hair, providing great convenience for hair care.

[0003] Most of the existing liquid-guiding combs adopt the method of setting the liquid tank in the middle of the shell, and the gap between the liquid tank and the shell is used to place the electronic components such as the electric control board and the battery, and the liquid tank and the shell are sealed and waterproofed by a sealing gasket. In the existing electric liquid-guiding comb, the shell is generally round, the electric control board is plate-shaped, and the battery is rectangular. Since the liquid tank is located in the middle of the shell, the gap around the liquid tank inside the shell is used to install the electronic components such as the electric control board and the battery, which makes the space between the shell and the liquid tank small, increasing the difficulty of assembling the electronic components.

[0004] For example, the Chinese utility model patent application number is: 202020501046.2, and its name is a multifunctional vibration introduction massage comb. Its shell 1 is circular, and the accommodating cavity 18 is located in the middle of the shell 1. The electric control board and the battery are arranged in the gap between the accommodating cavity 18 and the shell 1. Due to the limitations of the gap space structure and the shape of the electric control board and the battery, the volume of the shell often needs to be enlarged to accommodate the motherboard, but this does not meet the design requirements of portability and lightness, and enlarging the outer diameter of the shell will also increase the material cost. At the same time, when adding liquid to the liquid tank, if the liquid overflows from the liquid injection port, it is easy to enter the gap and cause damage to the electronic components, and the waterproof performance is poor.
