Description

Technical Field

[0001] This utility model relates to the field of personal care device technology, specifically to a lever-type switch button for a personal care device and a personal care device. Background Technology

[0002] Personal care devices such as curling irons and hair dryers are prevalent. Hair dryers are primarily used for drying and styling hair, and most currently use toggle switches for adjusting settings, such as wind speed and power on / off. However, existing hair dryers require more functions to meet different needs. For example, when the nozzle is replaced with a curling iron nozzle, higher temperatures are needed, or an ionizer function can be added. These needs are often not met by toggle switches, thus requiring an additional tactile switch. Currently, tactile switches are typically triggered by a pressable button. Most existing buttons use a linear movement method to trigger the tactile switch located below the button. This structure requires a large travel distance for the button, which is unsuitable for the small-diameter grip design. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lever-type switch button for a personal care device and a personal care device.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An installation space is provided within the main body, and the installation space is provided with a pressing notch corresponding to the tactile switch;

[0008] A rocker has a pivot at one end that is connected to the mounting space, and the other end rests on the pressing end surface of the tactile switch. Under the action of external force, the rocker swings inward toward the main body with the pivot as the axis of rotation, and triggers the tactile switch.

[0009] It includes a mounting bracket disposed within the main body and a circuit board disposed at the bottom of the mounting bracket. The circuit board is provided with a tactile switch, and the mounting bracket is provided with an installation space. The rocker is rotatably disposed within the installation space.

[0010] The installation space includes a first mounting slot for accommodating the rocker and a second mounting slot for mounting the pivot. The first mounting slot and the second mounting slot are connected and arranged along the axis of the mounting bracket.

[0011] The first mounting groove is provided with a pressing notch, and the rocker plate partially contacts the tactile switch through the pressing notch under the action of external force.

[0012] The rocker includes a pressing part and a rotating shaft located at one end of the pressing part.

[0013] The pressing part has a through hole at its center, through which light from the light-emitting element installed in the main body can pass.

[0014] A detachable button is located above the pressing part.

[0015] The button is coaxially aligned with the through hole, and the surface of the button is provided with a light-transmitting layer.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] This utility model discloses a lever-type switch button for personal care devices, which can be applied to various personal care devices, such as curling irons, razors, hair clippers, and hair dryers.

[0030] This utility model takes a hair dryer as an example. It generally includes a main body 10 with normal hair dryer function and a shell that at least partially covers the main body. The lever-type switch button is preferably restricted to the surface of the main body by the shell.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the lever-type switch button includes a tactile switch and a rocker. The rocker is rotatably mounted on the main body. The rocker swings relative to the rotating shaft by the pressing force, which triggers the tactile switch. The length design between the pressing part of the rocker and the rotating shaft can be used to adjust the pressing stroke, thereby achieving the minimum pressing stroke design.

[0032] The tactile switch 310 is located inside the main body 10. The tactile switch 310 is generally carried by a circuit board and fixedly installed inside the main body.

[0033] An installation space is provided within the main body 10, and the installation space is provided with a pressing notch corresponding to the tactile switch 310. The installation space can be directly formed by a recess on the inner shell of the main body to form a corresponding installation groove, or it can be fixed to the inner shell of the main body by an additional installation bracket.

[0034] The rocker 200 has a rotating shaft 230 at one end that is connected to the installation space, and the other end rests on the pressing end surface of the tactile switch 310. Under the action of external force, the rocker 200 swings inward toward the main body with the rotating shaft 230 as the axis of rotation, and triggers the tactile switch 310.

[0035] Example

[0036] The lever-type switch button includes a mounting bracket 100 disposed within the main body 10 and a circuit board 300 disposed at the bottom of the mounting bracket 100. The circuit board 300 is provided with a tactile switch 310. The mounting bracket 100 is provided with an installation space, and the rocker 200 is rotatably disposed within the installation space.

[0037] The circuit board is supported by the inner shell of the main body and is positioned between the mounting bracket and the inner shell. The surface of the inner shell can be provided with corresponding limiting components to ensure that the position of the circuit board does not shift. In other embodiments, the circuit board can also be directly fixedly connected to the bottom of the mounting bracket, depending on the design requirements.

[0038] Once installed, the circuit board has a tactile switch positioned directly below the pressing surface 210 of the rocker arm. This means the pressing surface of the rocker arm rests on the pressing end of the tactile switch, allowing the rocker arm to trigger the tactile switch when pressure is applied. Compared to a linear pressing structure, which may cause jamming when its linearity is disrupted, the rocker arm design prevents jamming and ensures the constant effectiveness of the switch button.

[0039] like Figure 7 As shown, the installation space includes a first mounting groove 120 for accommodating the rocker arm 200 and a second mounting groove 110 for mounting the rotating shaft 230. The first mounting groove 120 and the second mounting groove 110 are connected and arranged along the axial direction of the mounting bracket 100. The second mounting groove is used to restrict the rotating shaft to ensure that the rotating shaft can rotate relative to each other within the second mounting groove. The bottom of the first mounting groove 120 is provided as a pressing notch. Under the action of external force, the rocker arm 200 partially contacts the tactile switch 310 through the pressing notch.

[0040] like Figure 8 As shown, the rocker 200 includes a pressing part 260 and a rotating shaft 230 disposed at one end of the pressing part 260. The pressing part 260 and the rotating shaft are integrally formed, and there are two rotating shafts, which are symmetrically disposed on both sides of the pressing part.

[0041] like Figure 4 and Figure 5As shown, the pressing part 260 has a through hole 240 at its center, through which light from the light-emitting element 320 disposed in the main body 10 can pass. Preferably, the light-emitting element 320, such as a light-emitting diode, is disposed on the circuit board, which serves as an indicator during operation.

[0042] A detachable button 400 is provided above the pressing part 260. The pressing part 260 has a connecting wall 250 around the through hole 240. The connecting wall 250 has a positioning notch 270. The button is cylindrical and is divided into an inner ring and an outer ring. The inner ring is inserted into the through hole, and the outer ring is located outside the connecting wall. A positioning block is provided between the inner ring and the outer ring. When the button and the pressing part are engaged, the positioning block and the positioning notch are engaged. The two are fixedly connected by an interference fit.

[0043] To improve light transmission, the button 400 and the through hole 240 are coaxially aligned, allowing the light beam to pass directly through the inner ring and preventing leakage from the side. The button 400 has a light-transmitting layer on its surface, which can be the same diameter as the inner ring and can have corresponding patterns on its surface to make the indication clearer. Different indication functions can also be achieved by changing the color of the light.

[0044] like Figure 6 As shown, the surface of the pressing part 260 is provided with a protrusion 220. After it is installed in the main body, the protrusion 220 contacts the inner wall of the outer shell. The protrusion ensures that the exposed button is in a horizontal state with the outer shell. Thus, when not in use, the button is in a flat state, making the whole more aesthetically pleasing.

[0045] This utility model also discloses a personal care device, which is a high-speed hair dryer. The device is rod-shaped and includes a main body 10. The lever-type switch button 20 for the personal care device is provided on any side of the main body.

[0046] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
