Description

This application relates to the technical field of hair removal devices, and more specifically to hair removal devices. Light-based hair removal, a new commercially available hair removal technology and cosmetic method, uses strong pulsed light of a specific wavelength to destroy hair follicles, achieving permanent hair removal. It offers advantages such as speed, effectiveness, high safety, no side effects, and painlessness, and is widely welcomed in the cosmetic and medical industries. Existing hair removal devices typically use a vortex fan to cool and dissipate the heat generated inside, but if the internal temperature of the device becomes too high, it can easily pose a safety hazard. Therefore, preventing excessive temperature buildup inside hair removal devices and reducing safety hazards is a technical challenge that needs to be addressed urgently. Embodiments of this application provide a hair removal device, the hair removal device comprising: a cooling drive unit provided with a drive port and capable of outputting a cooling medium via the drive port; a housing in which the cooling drive unit is fixed, the housing being provided with an air outlet, a cooling channel docked to the drive port and communicating with the air outlet, and a light output port communicating with the cooling channel; a hair removal device located within the housing and fixed within the cooling channel; a cooling application unit fixed to the light output port and facing the hair removal device, which receives and emits light emitted from the hair removal device; a heat conduction unit fixed within the housing, one end of which is located within the cooling channel and the other end of which is connected to the cooling application unit ; a temperature control device mounted within the housing, located on the side of the heat conduction unit away from the cooling drive unit and near the air outlet; and a control board fixed within the housing and electrically connected to the cooling drive unit, the hair removal device, the cooling application unit and the temperature control device . In the hair removal device provided by this application, a cap is installed inside the housing, one end of the cap is attached to the air outlet of the housing to seal the air outlet, and the other end of the cap is connected to a heat conduction part. The cap is provided with an air permeable hole and an air guide hole. The air guide hole, one end of which communicates with a cooling channel and the other end of which communicates with an air permeable hole, is used to concentrate the hot air from the cooling channel together with the air permeable hole, blow it into the air permeable hole with a cooling medium, and release it from the air permeable hole. The cooling medium is preferably cooling air. The cap enables concentrated airflow. The cooling channel consists of a first cooling channel and a second cooling channel. The cap collects the hot air from the first and second cooling channels and guides the hot air to the air guide hole and air permeable hole, thereby isolating the blown-out hot air from the internal cavity of the housing. Thus, it is possible to prevent the hot air from re-entering the housing after it has been released, and at the same time, it is possible to prevent backflow of hot air and improve both heat dissipation efficiency and heat dissipation effect. Furthermore, the temperature control device is mounted on the cap and positioned on the inner wall of the air guide hole. When it detects that the temperature of the hot air from the air guide hole is too high, it transmits this information to the control board. The control board then stops the operation of the hair removal device, thereby avoiding safety hazards resulting from excessively high internal temperatures in the housing.
