[0026] Reference Figure 1 The embodiments of the present application provide an electric hair dryer, which comprises a handle 1, and a switch structure 2 is arranged on the handle 1. The switch structure 2 is a sliding switch, which is used to turn on or off the blowing function of the electric hair dryer.

[0027] In some embodiments, the switch structure 2 can include a housing 21, a static contact 22, a spring 23, and a sliding body 27. The housing 21 has an opening 21a. The static contact 22, the spring 23, and the sliding body 27 are disposed in the housing 21. The spring 23 is provided with a dynamic contact 24 corresponding to the static contact 22. The sliding body 27 is slidably disposed in the housing 21 and is used to act on the spring 23 to make the dynamic contact 24 and the static contact 22 contact or separate. Specifically, the housing 21 is provided with a first pin 25 and a second pin 26, the first pin 25 is connected with the static contact 22, and the second pin 26 is connected with the spring 23 and the dynamic contact 24. When the sliding body 27 slides relative to the housing 21 in a first direction (indicated as a left direction), Figure 1 the sliding body 27 can press the spring 23, the spring 23 deforms so that the dynamic contact 24 on the spring 23 contacts the static contact 22, thereby making the first pin 25 and the second pin 26 conductive. When the sliding body 27 slides relative to the housing 21 in a second direction (indicated as a right direction), Figure 1 the sliding body 27 can release the pressing action on the spring 23, the spring 23 returns to its original state so that the dynamic contact 24 on the spring 23 separates from the static contact 22, thereby making the first pin 25 and the second pin 26 disconnected. However, the embodiments of the present application do not make any limitation in this regard.

[0028] In some embodiments, the sliding body 27 can be provided with a protrusion 27a extending out of the opening 21a. In use, the protrusion 27a can receive a pushing force and drive the sliding body 27 to slide relative to the housing 21 under the action of the pushing force, thereby making the dynamic contact 24 contact or separate from the static contact 22. However, the embodiments of the present application do not make any limitation in this regard.

[0029] In some embodiments, the protrusion 27a can be provided with a baffle 28, the baffle 28 is attached to the outer wall of the housing 21 and covers the opening 21a at all times when the sliding body 27 slides. Specifically, the baffle 28 is fixed to the protrusion 27a and attached to the outer wall of the housing 21, when the sliding body 27 slides, the baffle 28 can slide relative to the housing 21, and the baffle 28 can cover the opening 21a of the housing 21 at all times during the sliding process. In this way, it can prevent fine hairs from entering the inside of the housing 21 from the opening 21a of the housing 21 or the gap between the housing 21 and the sliding body 27, so as to avoid the accumulation of hairs in the housing 21 affecting the effective contact of the dynamic contact 24 and the static contact 22, thereby improving the reliability of the switch structure 2 and reducing the product return rate after sale. However, the embodiments of the present application do not make any limitation in this regard.

[0030] In some embodiments, the baffle 28 can be rubber, plastic, or metal. However, the embodiments of the present application do not make any limitation in this regard.

[0031] In some embodiments, the baffle 28 and the protrusion 27a are an integral structure. In this way, the connection strength between the baffle 28 and the protrusion 27a can be improved, and the baffle 28 can be prevented from moving relative to the protrusion 27a to cause a gap between the baffle 28 and the shell 21, thereby affecting the sealing of the switch structure 2.

[0032] In some embodiments, the baffle 28 is detachably arranged on the protrusion 27a. For example, the baffle 28 is sleeved on the protrusion 27a and sealingly connected with the protrusion 27a. In this way, the processing difficulty of the parts can be reduced, thereby facilitating the reduction of production cost.

[0033] In some embodiments, in order to sealingly connect the baffle 28 and the protrusion 27a, a sealing structure can be arranged between the baffle 28 and the protrusion 27a. For example, a sealing ring is arranged on the outer periphery of the protrusion 27a, and the baffle 28 is sleeved outside the sealing ring.

[0034] In some embodiments, the sliding body 27 is arranged to limit the movement of the protrusion 27a along the direction of the opening 21a. For example, the sliding body 27 is located between the shell 21 and the elastic sheet 23, and the sliding body 27 is in close contact with the inner wall of the shell 21 under the elastic force of the elastic sheet 23. In this way, the movement of the sliding body 27 along the direction of the opening 21a can be prevented, thereby preventing the movement of the protrusion 27a along the direction of the opening 21a, so that the baffle 28 can be kept in close contact with the outer surface of the shell 21 without a gap.

[0035] In some embodiments, the switch structure 2 further comprises a push button 29 connected to the protrusion 27a, and the push button 29 is used to transmit a pushing force to the protrusion 27a to make the sliding body 27 slide relative to the shell 21. Figure 1 As shown, the push button 29 is arranged in the through hole of the handle 1 and connected with the protrusion 27a. During use, a user can apply a pushing force to the push button 29 to make the push button 29 drive the sliding body 27 to slide relative to the shell 21.

[0036] One or more embodiments of the present specification are intended to cover all such alternatives, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omission, modification, equivalent replacement, improvement, etc. made within the spirit and principle of one or more embodiments of the present specification shall be included in the protection scope of the present application.

[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which shall be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
