The switch module as referred to herein is a module that can control the operation of an electric appliance based on an on/off function to function as a switch, and its circuit configuration can be designed correspondingly as needed, and will not be described in detail herein. Fig. 2 shows a length direction a and a width direction b of the switch mechanism, which are coincident with a length direction of the handle of the hair dryer when the switch mechanism is applied to the hair dryer. As shown in fig. 2, the first switch unit 21, the switch lever 1, and the second switch unit 22 are provided in this order along the longitudinal direction a of the switch mechanism, so that the space occupied by the switch mechanism in the width direction can be significantly saved and the space for installing other components can be provided, as compared with the case where the switch mechanism is provided along the width direction of the handle, that is, the lateral direction identical to the longitudinal direction of the housing in the related art. It should be noted that, although the switch mechanism is applied to the hair dryer in the present embodiment, the switch mechanism may be applied to all home appliances requiring a compact layout.

Specifically, as shown in fig. 3 and 4, the switch operating lever 1 includes a first lever main body 11, a first connecting portion 13 extending from the first lever main body 11 in the longitudinal direction a, a second lever main body 12, and a second connecting portion 14 extending from the second lever main body 12 in the longitudinal direction a.

Since the operation of the second lever body 12 is similar to that of the first lever body 11, a repeated explanation of the action of the second lever body 12 is omitted.

Fig. 2 and 5 show a first position P1 and a second position P2 of the first switch assembly 21, in this embodiment, the first switch assembly 21 is used to control the on or off of the blower, when the first slider 212 is in the first position P1, the blower is off, when the first slider 212 is in the second position P2, the blower is on, and the motor in the housing starts to operate to introduce outside air. The number and function of the first position P1 and the second position P2 are exemplary, and a third position (not shown) may be provided as desired, and the first position P1 and the second position P2 may be cold-hot related or power related, for example, the first position P1 corresponds to a cold air mode and the second position P2 corresponds to a hot air mode, or the first position P1 corresponds to a high power mode and the second position P2 corresponds to a low power mode. The first switch module 21 may be provided with different pins and connected to a circuit module not shown, so that the functions of the first position P1 and the second position P2 may be changed. These circuit designs are prior art and therefore not described in great detail.

The "first slider 212 is at the first position P1" means that the initial position of the first slider 212 is the first position P1 or moves from the second position P2 to the first position P1 by the first lever main body 11. As shown in fig. 5, when the user pushes one of the pressing portions 17 upwards, the first lever body 11 is forced to move upwards, so that the first connecting portion 13 is driven to move upwards, and the first opening portion 132 also drives the first slider 212 to move upwards to stay at the second position P2. The "staying at the second position P2" can be realized by various methods in the prior art, but is not limited herein, for example, an elastically deformable engaging member is provided, and after the first slider 212 passes over the engaging member, the engaging member is supported by returning to its original state, and stays at the second position P2. When the first slider 212 stays at the second position P2, communication between the first switch assembly 21 and the not-shown circuit assembly is triggered and the blower is activated. Here, the trigger system is not particularly limited, and for example, a system such as engagement of the first slider 212 with a contact switch is used.

In the present embodiment, the double switch module 2 is provided and the layout thereof is designed, specifically, the first switch module 21, the switch lever 1, and the second switch module 22 are provided in order along the longitudinal direction a of the switch mechanism, so that the overall design in the longitudinal direction a is utilized to save the lateral space.
