Description

Technical Field

[0001] The utility model relates to the field of electric hair clippers, in particular to an electric hair clipper with a cooling function for the cutter head. Background Art

[0002] An electric hair clipper is a commonly used tool for trimming human hair or animal hair. When the electric hair clipper is working, the blades in the cutting unit rotate relative to each other at high speed and rub against each other, generating a large amount of heat, which causes the temperature of the cutting unit to rise. When the skin comes into contact with the cutting unit, this high temperature will cause discomfort to the skin. Therefore, when the cutter head is at a high temperature, it is necessary to cool it down. In the existing cooling structures, most of them use a fan to cool the temperature of the blades. However, this method has a poor cooling effect, and the internal heat dissipation depends solely on the fan, resulting in a poor heat dissipation effect and a deteriorated use effect of the electric hair clipper.

[0003] A Chinese patent document CN117774011A discloses an electric hair clipper, which is characterized in that: it includes a housing, a cutter head, a driving motor one, a driving motor two and a fan. The driving motor one is installed in the housing, the output end of the driving motor one is connected to the cutter head, and the driving motor one is used to drive the cutter head to move. The driving motor two is installed in the housing, the output end of the driving motor two is connected to the fan, an air outlet channel is arranged in the housing, and an air outlet is arranged at the end of the housing. The driving motor two is used to drive the fan to rotate, so that the air generated by the fan passes through the air outlet channel and the air outlet in sequence and blows towards the cutter head. The structure of this electric hair clipper mainly uses a driving motor to drive a fan to cool the cutter head and internal components of the electric hair clipper. This method has a poor cooling effect, and there is no heat dissipation component inside, and the heat dissipation effect is also not good. Therefore, we have designed an electric hair clipper with a cooling function for the cutter head, which has a refrigerating sheet inside. When the cutter head reaches a certain temperature, the refrigerating sheet will cool the cutter head, and a heat dissipation structure is also provided to dissipate heat from the cutter head and the internal motor at the same time.
