Description

Technical Field

[0001] This utility model relates to the technical field of control switches, and in particular to a control switch with protective function. Background Technology

[0002] Electric hair clippers, as power tools for trimming hair, are widely used in people's lives. A typical electric hair clipper consists of a housing, a bladed head, a drive mechanism to operate the blades, and a switch to control the start and stop of the drive mechanism. Current electric hair clipper switches are generally push-button or lever-type. Lever-type switches typically include a lever and a conductive switch piece. Moving the lever moves the switch piece, turning the clipper on or off, thus enabling the electric hair clipper to be turned on and off.

[0003] For example, a Chinese utility model patent (publication number: CN216831006U) discloses an electric hair clipper, which includes a housing, a switch assembly mounted on the housing, and a main body of the mechanism. The switch assembly includes a lever and a fixing member. In practical use, it has the following disadvantages: (see attached...) Figure 1 As shown, since there is a gap between the lever 11' and the fixing member 12' of the switch assembly 1', when the electric hair clipper is trimming hair, the cut hair will enter the interior of the switch assembly 1' through the gap between the lever 11' and the fixing member 12'. The hair entering the interior of the switch assembly 1' will affect the contact conduction function of the switch plate, thereby affecting the normal start-up and shutdown of the electric hair clipper.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where a gap exists between the lever and the fixing part of the switch assembly. When the electric hair clipper is trimming hair, the cut hair can enter the interior of the switch assembly through this gap, affecting the contact and conduction function of the switch piece, and thus affecting the normal start-up and shutdown of the electric hair clipper. Therefore, this invention proposes a control switch with protective function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A control switch with protective function includes a switch assembly. The switch assembly includes a lever and a fixing member for mounting the lever. The fixing member has a notch for mounting the lever. A first end of the lever extends into the fixing member and is hinged thereto. A second end of the lever extends out of the fixing member. A flexible rubber pad is sleeved on the outer periphery of the lever. The rubber pad covers the notch, and when the lever is moved, the rubber pad is deformed by the lever so that the rubber pad always covers the gap formed between the notch and the lever.

[0008] Furthermore, the periphery of the soft rubber pad is fixedly connected to the fastener.

[0009] Furthermore, the fastener is provided with snap-fit ​​parts for fixing the two ends of the soft rubber pad, and the two ends of the soft rubber pad are provided with snap-fit ​​interfaces that engage with the snap-fit ​​parts.

[0010] Furthermore, the fastener is provided with a T-shaped locking block for fixing the side of the soft rubber pad, and the side of the soft rubber pad is provided with a strip-shaped notch that engages with the T-shaped locking block.

[0011] Furthermore, the soft rubber pad is provided with a through hole that mates with the lever, and the inner sidewall of the through hole is in close contact with the outer sidewall of the lever.

[0012] Furthermore, the upper surface of the soft rubber pad is provided with a protrusion, which surrounds the periphery of the through hole; the lower surface of the soft rubber pad is provided with an annular groove, which surrounds the periphery of the through hole.

[0013] Furthermore, the soft pad is made of silicone or rubber.

[0014] Furthermore, the second end of the lever is provided with a gripping part.

[0015] Furthermore, the lever can be moved between a first position and a second position relative to the fixing member, and the fixing member is provided with a first mark corresponding to the first position and a second mark corresponding to the second position.

[0016] The beneficial effects of this utility model after adopting the above structure are as follows: The control switch with protective function described in this utility model includes a switch assembly. The switch assembly includes a lever and a fixing member for mounting the lever. The fixing member has a notch for mounting the lever. A first end of the lever extends into the fixing member and is hinged thereto. A second end of the lever extends out of the fixing member. A flexible rubber pad is fitted around the outer periphery of the lever. The rubber pad covers the notch, and when the lever is moved, the rubber pad deforms due to the lever, ensuring that the rubber pad always covers the gap formed between the notch and the lever. The flexible rubber pad covering the notch of the fixing member in this utility model covers the gap formed between the notch and the lever. When the lever is moved, the rubber pad deforms due to the lever, thus ensuring that the gap between the notch and the lever is always covered, preventing hair from entering the interior of the switch assembly through the gap between the notch and the lever, and improving the reliability of the switch assembly.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] In the description of this utility model, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figures 2 to 10 As shown, a control switch with protective function includes a switch assembly 1. The switch assembly 1 includes a lever 11 and a fixing member 12 for mounting the lever 11. The fixing member 12 is provided with a notch 121 for mounting the lever 11. A first end of the lever 11 extends into the fixing member 12 and is hinged to the fixing member 12. A second end of the lever 11 extends out of the fixing member 12. A flexible rubber pad 13 is sleeved on the outer periphery of the lever 11. The rubber pad 13 covers the notch 121. When the lever 11 is moved, the rubber pad 13 is deformed by the lever 11 so that the rubber pad 13 always covers the gap formed between the notch 121 and the lever 11.

[0038] Based on the above embodiments, the present invention aims to provide a control switch with a protective function, including a switch assembly 1. The switch assembly 1 includes a lever 11 and a fixing member 12 for mounting the lever 11. The fixing member 12 is provided with a notch 121 for mounting the lever 11. The first end of the lever 11 extends into the fixing member 12 and is hinged to the fixing member 12. The second end of the lever 11 extends out of the fixing member 12. A flexible rubber pad 13 is sleeved on the outer periphery of the lever 11. The rubber pad 13 covers the notch 121. When the lever 11 is moved, the rubber pad 13 is deformed by the lever 11, so that the rubber pad 13 always covers the gap formed between the notch 121 and the lever 11. The notch 121 of the fixing member 12 of this utility model is covered with a flexible soft rubber pad 13 to cover the gap formed between the notch 121 and the lever 11. When the lever 11 is moved, the soft rubber pad 13 is deformed by the lever 11, thereby always covering the gap formed between the notch 121 and the lever 11, preventing hair from entering the interior of the switch assembly 1 through the gap between the notch 121 and the lever 11, and improving the reliability of the switch assembly 1.

[0039] In another preferred embodiment of this utility model, the periphery of the soft rubber pad 13 is fixedly connected to the fixing member 12. The fixing member 12 is provided with snap-fit ​​portions 122 for fixing both ends of the soft rubber pad 13, and both ends of the soft rubber pad 13 are provided with snap-fit ​​interfaces 131 that engage with the snap-fit ​​portions 122. The fixing member 12 is provided with T-shaped snap-fit ​​blocks 123 for fixing the sides of the soft rubber pad 13, and the sides of the soft rubber pad 13 are provided with strip-shaped notches 132 that engage with the T-shaped snap-fit ​​blocks 123. In this embodiment, as... Figure 9 and Figure 10 As shown, when installing the soft rubber pad 13, the snap-fit ​​interface 131 is snapped onto the snap-fit ​​part 122 to fix both ends of the soft rubber pad 13. In a further preferred embodiment, the upper end of the snap-fit ​​part 122 is provided with an outwardly bent portion 1221, which prevents the soft rubber pad 13 from detaching from the snap-fit ​​part 122. In this embodiment, as... Figure 8 and Figure 10 As shown, when installing the soft rubber pad 13, the strip notch 132 is fitted onto the T-shaped clip 123 to fix the side of the soft rubber pad 13.

[0040] As another preferred embodiment of this utility model, the soft rubber pad 13 is provided with a through hole 133 that mates with the lever 11, and the inner sidewall of the through hole 133 is tightly attached to the outer sidewall of the lever 11. In this embodiment, as... Figure 4 and Figure 6As shown, the design of this structure ensures that the lever 11 and the through hole 133 of the soft rubber pad 13 fit as tightly as possible, preventing hair from entering the interior of the switch assembly 1 through the gap between the notch 121 and the lever 11.

[0041] As another preferred embodiment of this utility model, the upper surface of the soft rubber pad 13 is provided with a protrusion 134, the protrusion 134 surrounding the periphery of the through hole 133; the lower surface of the soft rubber pad 13 is provided with an annular groove 135, the annular groove 135 surrounding the periphery of the through hole 133. In this embodiment, as... Figure 8 and Figure 9 As shown, the protrusion 134 increases the contact area between the through hole 133 and the lever 11, which helps to reduce the gap between them. The annular groove 135 helps to increase the deformation of the soft rubber pad 13, so that the soft rubber pad 13 can deform as the position of the lever 11 changes, thereby ensuring that the soft rubber pad 13 always covers the gap between the notch 121 of the fixing member 12 and the lever 11.

[0042] In another preferred embodiment of this invention, the soft rubber pad 13 is made of silicone or rubber. In this embodiment, silicone or rubber has good flexibility and elasticity, and the use of silicone or rubber for the soft rubber pad 13 facilitates its deformation as the position of the lever 11 changes. Of course, in other preferred embodiments, the soft rubber pad 13 can also be made of other flexible materials with equivalent functions.

[0043] As another preferred embodiment of this utility model, the second end of the lever 11 is provided with a gripping portion 111. In this embodiment, as... Figure 3 As shown, the grip 111 is disposed at the second end of the lever 11 that extends out of the fixing member 12, and the grip 111 is exposed outside the housing 2 of the electric clipper, making it convenient for the user to operate.

[0044] As another preferred embodiment of this utility model, the lever 11 can be moved relative to the fixing member 12 between a first position and a second position. The fixing member 12 is provided with a first mark 124 corresponding to the first position and a second mark 125 corresponding to the second position. In this embodiment, as... Figure 10 As shown, the first position is the power-on position and the second position is the power-off position. Correspondingly, the first identifier 124 is "1" and the second identifier 125 is "0", which allows users to quickly confirm the power-on and power-off status of the electric clipper.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
