Description

Technical Field

[0001] The utility model relates to the technical field of hair removal devices, and particularly relates to a shell structure of a hair removal device. Background Technique

[0002] A hair removal device refers to a small electrical appliance used to remove body hair, such as armpit hair, leg hair, etc., to achieve the effect of reducing or eliminating hair.

[0003] For example, in patent document CN111700725A, a hair removal device includes: a heat conduction plate provided with a main heat absorption part, a first heat absorption part, a second heat absorption part and a heat outlet part. The main heat absorption part, the first heat absorption part and the second heat absorption part are all connected to the heat outlet part to conduct the heat they absorb to the heat outlet part, and then the heat outlet part conducts the heat out; a cold compress part, one side of which is attached to the main heat absorption part to conduct its own heat to the main heat absorption part to achieve cooling, and the other side is attached to the user's skin to perform cold compress on the user's skin; a hair removal device fixed on one side of the cold compress part for emitting light passing through the cold compress part; a control device including a processor and a capacitor, the processor and the capacitor are respectively attached to the first heat absorption part and the second heat absorption part to conduct their own heat to the first heat absorption part and the second heat absorption part; a heat dissipation part attached to the heat outlet part to dissipate heat from the heat outlet part.

[0004] For example, patent document CN115770103A discloses a laser hair removal device, including a shell, a semiconductor laser, a light guiding component and a heat dissipation mechanism. The semiconductor laser is arranged in the shell and emits a laser beam in a predetermined direction; the light guiding component is arranged in the shell and is located in the predetermined direction to diffuse the laser beam outward; the heat dissipation mechanism is arranged in the shell and is thermally conductively connected to the semiconductor laser and the light guiding component respectively to jointly dissipate heat from the semiconductor laser and the light guiding component.

[0005] Referring to the above patent documents and existing hair removal devices on the market, currently, hair removal devices mainly assemble the main body structure by snapping or screwing two or more components together, that is, adopting the assembly form of an upper shell and a lower shell. In actual use, the following technical problems mainly exist:

[0006] 1. Poor structural stability. Since the main body is assembled, when it accidentally drops or is severely dropped, the main body shell is prone to cracking. Because there is high voltage inside, cracking is very likely to cause safety problems.

[0007] 2. Weak structural integrity. During the user's use of the main body, the product function is prone to failure due to electrostatic ESD.

[0008] 3. Poor overall appearance of the multi-component assembled product. Since it is a class II medical product, it is not convenient to clean and maintain during use and is prone to breeding bacteria.

[0009] Therefore, improvements need to be made in this regard. Content of the Utility Model
