Use; after use, cover the cover on the cutter head, the cover does not drive the control switch, and the cutter head does not work.

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in FIG. 2-11, the present invention discloses an electric razor 100, comprising a housing 10, a driving motor 50 fixed on the housing 10, and a housing 10 fixed to the housing 10. a cutter head 80 at the first end 11 and a power supply device 50 for supplying power to the drive motor 60. The drive motor is coupled to the cutter head and drives the cutter head. The electric razor 100 further includes a heat generating component for generating heat. 47. The power supply device 50 is electrically connected to the heat generating component 47 for supplying power to the heat generating component 47 to heat the heat generating component 47, and the heat generating component 47 and the driving motor 60 are both connected to the power supply device. The housing 10 is provided with a first escaping hole 13 for escaping the heat generating member 47. The first escaping hole 13 is a circular hole having a diameter of more than 7.8 mm. The diameter ranges from 7.8 mm to 9.5 mm, which facilitates the insertion of the ignited article into the first escape hole to cooperate with the heat generating member. The heating element comprises a heating wire, and the wire is surrounded by a circular ring structure, and the wire size is suitable for the first escape hole setting.

As shown in FIGS. 3-5 and 7, the electric razor 100 further includes a closing cover 30 for closing the first escaping hole 13; the closing cover protects the heating element, not only preventing the heating element from being Damaged or dusty when not in use; and prevents the user from inadvertently touching the heat generating component and being injured; will be closed when in use The cover can be removed or removed, which is simple and convenient. The closing cover is provided with a control block 31, the housing is provided with a second avoiding hole 14 for avoiding the control block, and the control block 31 is slidable in the second avoiding hole 14 to push the The control block triggers the heat switch 42 of the electric razor to cause the power supply device 50 to communicate with the heat generating member 47 when the closing cover is removed from the first escape hole. The control block is slidable in the second escape hole. When the closing cover is removed from the first escape hole, that is, when the first escape hole is completely exposed, the control block opens the heat switch to make the power supply device supply power to the heat generating component, thereby heating the heat generating component. . The closing cover not only seals the first escaping hole to prevent the heating element from being damaged or falling into dust when not in use, but also directly pushes the closing cover to open the heating switch to make the heating element heat, convenient to use and simple to operate.
