[0002] Some hair trimmer products are provided with switch keys on the machine body, and the functions of starting and closing the power are realized by pressing the switch keys, in order to avoid water entering the switch key, a waterproof structure is usually arranged at the switch key. The traditional waterproof structure generally adopts the mode of arranging a soft rubber between the switch key and the circuit board switch element for waterproofing, and the soft rubber is hot-pressed or rubberized on the cylinder body, because the hot-pressing or rubberizing process is prone to poor pressing or loose rubberizing, which leads to a decrease in sealing performance and a failure in waterproofing. Figure 1 When the switch key touches the switch element, the soft rubber 6 is easily broken by the switch key after a long time of pressing, which leads to a failure in waterproofing and a short service life of the product. In addition, in order to enable the switch key to automatically pop up and reset after being pressed, a spring 5 or a spring sheet and other parts need to be installed to drive the switch key to reset, and the structure is relatively complex and the production cost is high.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] See Figures 2-7This utility model provides a waterproof switch structure, including: a body 1 suitable for mounting on a hair trimmer; a switch element 2 and a pressable switch button 3 mounted on the body 1; the switch button 3 being disposed on one side of the switch element 2; the waterproof switch structure includes a flexible sealing element 4 connected between the body 1 and the switch button 3; a top block 301 for actuating the switch element 2 is provided on the side of the switch button 3 near the switch element 2; and a clearance groove 101 for avoiding the top block 301 is provided on the body 1. The sealing element 4 is annularly abutted against the periphery of the clearance groove 101. When the top block 301 touches the switch element 2, it will not touch the sealing element 4, so that the sealing element 4 will not be worn or broken by the top block 301, resulting in a long service life. This utility model has a waterproof switch structure and hair trimmer with a simple structure and low production cost. By the sealing element annularly abutting against the periphery of the clearance groove, water is prevented from entering the machine body through the clearance groove. After pressing and releasing the switch button, the elasticity of the sealing element itself can drive the switch button to reset. The number of parts is reduced, further reducing the production cost.

[0026] See Figure 3 , Figure 4 and Figure 7 The sealing element 4 is annular, with one end abutting against the body 1 and the other end abutting against the switch button 3. The sealing element 4 abuts against the body 1 and the switch button 3 at both ends, thereby achieving a sealing and waterproofing effect, preventing external water from entering the body 1 through the clearance groove 101, and preventing damage to the components inside the body 1 from water. The sealing element 4 is provided with a first sealing protrusion 401 abutting against the switch button 3 and a second sealing protrusion 402 abutting against the body 1 to increase the sealing effect. Both the first sealing protrusion 401 and the second sealing protrusion 402 are annular. In this embodiment, there are three first sealing protrusions 401 and two second sealing protrusions 402.

[0027] See Figures 5-7The sealing element 4 includes a first sealing block 41, a second sealing block 42, and a connecting block 43 connecting the first sealing block 41 and the second sealing block 42. The first sealing block 41 abuts against the switch button 3, thereby sealing between the first sealing block 41 and the switch button 3. The second sealing block 42 abuts against the body 1, thereby sealing between the second sealing block 42 and the body 1. Pressing the switch button 3 causes the connecting block 43 to elastically deform. After releasing the switch button 3, the connecting block 43 returns to its original deformation, causing the switch button 3 to spring back to its original position. The switch button 3 is provided with a slot 302, and the first sealing block 41 is locked into the slot 302. The locking is secure and the first sealing block 41 is not easily displaced, thereby making the sealing element 4 less prone to displacement and the sealing more reliable. The connecting block 43 is inclined, which facilitates the elastic deformation of the connecting block 43 when the switch button 3 is pressed, so that after releasing the switch button 3, the connecting block 43 returns to its original deformation, causing the switch button 3 to spring back to its original position. In this embodiment, the outer diameter of the first sealing block 41 is smaller than the outer diameter of the second sealing block 42.

[0028] See Figures 2-6 The sealing element 4 is made of elastic material. When the switch button 3 is pressed, the switch button 3 squeezes the sealing element 4, causing the sealing element 4 to undergo elastic deformation. When the switch button 3 is released, the sealing element 4 restores its elastic deformation, thereby driving the switch button 3 to reset to the side away from the switch element 2. The sealing element 4 is made of silicone or rubber to ensure sealing. At the same time, when the switch button 3 is released, the elasticity of the sealing element 4 can also drive the switch button 3 to reset.

[0029] See Figure 2 and Figure 6 The switch button 3 is provided with a buckle 303 that is suitable for engaging with the clearance slot 101. The buckle 303 ensures that the switch button 3 can only slide in the pressing direction and will not detach from the body 1.

[0030] See Figures 2-4 The switch element 2 is a push-button switch. A circuit board 103 is installed inside the body 1, and the switch element 2 is electrically connected to the circuit board 103. A groove 102 is provided on the body 1, and the switch element 2 and the switch button 3 are placed in the groove 102. The clearance groove 101 is opened on the inner bottom surface of the groove 102. The switch element 2 and the switch button 3 can be installed in a hidden manner on the body 1, making the structure more beautiful and neat. At the same time, the switch button 3 will not protrude too much from the body 1, avoiding accidental pressing of the switch button 3 during use.

[0031] The waterproof switch structure of this utility model is simple in structure and low in production cost. The sealing element, in a ring, abuts against the surrounding clearance groove, preventing water from entering the machine body through the clearance groove. When the switch button is pressed and released, the elasticity of the sealing element causes the switch button to reset. Fewer parts are required, further reducing production costs. The top block does not touch the sealing element when it abuts the switch element, preventing wear or breakage and extending the service life of the sealing element. The sealing element has a first sealing protrusion that abuts against the switch button and a second sealing protrusion that abuts against the machine body to enhance the sealing effect. The connecting block is inclined, allowing for elastic deformation when the switch button is pressed, so that when the switch button is released, the connecting block returns to its original shape, causing the switch button to spring back to its reset position. The switch element and switch button are placed within a groove, allowing for concealed installation on the machine body, resulting in a more aesthetically pleasing and neat structure. Simultaneously, the switch button does not protrude excessively from the machine body, preventing accidental pressing during use.

[0032] In addition, this utility model also provides a hair trimmer, including the above-mentioned waterproof switch structure. This hair trimmer also has the beneficial effects of the above-mentioned waterproof switch structure, which will not be described in detail here.
