Description

Technical Field

[0001] This utility model relates to the field of switch technology for hair clippers, and in particular to a lever switch and a hair clipper. Background Technology

[0002] Hair clippers, commonly including shavers and electric clippers, typically have two types of switches: a simple power switch that turns the clipper on or off, and a switch with adjustable speed settings. These switches use multiple function buttons on the clipper's casing to adjust speed, but this design has several drawbacks: First, multiple button holes on the casing disrupt the product's aesthetics and provide a pathway for dust, moisture, and hair debris to enter. Second, multiple independent operating components increase internal complexity and the number of parts, leading to higher production costs, more cumbersome assembly, and greater inconvenience for operators when adjusting speed settings. Therefore, there is an urgent need in this field for a simple, well-sealed, easy-to-operate lever switch solution that integrates speed control functionality. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a lever switch and a hair clipper, which solves the problems of poor safety, aesthetics and ease of operation of existing hair clippers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lever switch, including a hair clipper housing, a tactile switch disposed inside the housing, a lever, and a linear elastic element. The tactile switch includes an acceleration switch and a deceleration switch. The lever passes through the housing and is rotatably connected to the housing. The lever is configured to be tossed from outside the housing to selectively trigger the acceleration switch or the deceleration switch after swinging around its rotation point. The lever is elastically connected to the housing through the linear elastic element to provide an elastic restoring force after the lever swings.

[0005] Furthermore, the linear elastic element includes any one of springs, compression springs, elastic rubber, and elastic paddles.

[0006] By adopting the above technical solutions, multiple optional implementation methods for linear elastic elements have been identified, covering various materials and forms such as metal springs and non-metallic elastomers, providing sufficient flexibility for specific implementation.

[0007] Furthermore, the linear elastic element is a spring, and the lever and housing are respectively provided with mounting posts that are compatible with the spring for insertion.

[0008] By adopting the above technical solution, this connection method has significant advantages such as reliable connection and simple and convenient assembly. It can be quickly positioned and installed on the production line, which greatly improves assembly efficiency and reduces labor costs. The plug-in structure avoids the use of additional fasteners (such as screws or glue), further simplifying the bill of materials and assembly process. At the same time, it ensures that the spring will not fall off or shift during operation, ensuring the long-term stability of product performance.

[0009] Furthermore, the linear elastic element is positioned perpendicular to the direction in which the lever moves along the housing.

[0010] By adopting the above technical solution, the linear elastic element is set perpendicular to the direction of the lever's movement. This is an optimal force transmission layout. This layout can most effectively convert the linear deformation of the elastic element into the torque that drives the lever to reset, making the reset action more efficient and direct, requiring the least force, thus providing users with the lightest and most sensitive operating feel. At the same time, this vertical layout makes the force flow path of the entire structure most reasonable, avoiding unnecessary force components and friction, reducing wear on parts, and further improving the durability and reliability of the mechanism.

[0011] Furthermore, the direction of the lever's movement is parallel or nearly parallel to the end face of the housing where the lever is located.

[0012] By adopting the above technical solution, the lever moves in a parallel or nearly parallel manner along the end face of the housing. This operation method best matches the user's intuition about "toggling" a switch. The operation logic is clear and intuitive, and users can get started without learning, which greatly improves the user experience.

[0013] Furthermore, a contact block is provided on the part of the lever located inside the housing, so that when the lever is moved, the contact block can trigger an acceleration switch or a deceleration switch.

[0014] By adopting the above technical solution, a contact block is set inside the lever, which cleverly utilizes the lever principle when the lever swings. When the lever is moved, its contact block will trigger the corresponding tactile switch. Even if the travel of the switch element itself is very small, it can be effectively triggered. At the same time, setting the contact block on the lever makes the internal structure layout very compact and efficient. No additional transmission parts are needed, which simplifies the structure, reduces costs, and improves the response speed and accuracy of the triggering action.

[0015] Furthermore, a pivot is provided on the adjacent side of the lever and the contact block, and a corresponding shaft hole is provided on the inner wall of the housing. The lever is connected to the housing by inserting it into the shaft hole through the pivot.

[0016] By adopting the above technical solution, the plug-in connection between the rotating shaft and the shaft hole is one of the most classic and mature rotary connection methods in mechanical design. It has the advantages of simple structure, convenient processing, easy assembly and stable connection. This design ensures that the lever can swing smoothly and without wobbling around a precisely fixed axis, providing users with a stable and high-quality operating feel. At the same time, it also ensures that the touch block can be accurately aligned and trigger the corresponding tactile switch, improving the overall quality and performance consistency of the product.

[0017] Furthermore, the housing includes a bottom shell, an inner shell, and a front shell, with the inner shell located between the front shell and the bottom shell, and a circuit board for setting up a tactile switch located between the inner shell and the front shell.

[0018] By adopting the above technical solution, the design of the inner shell facilitates the optimization of the internal space of the casing, so as to separate and set up components such as power supply and motor, thereby improving safety.

[0019] Furthermore, a through hole is provided on the housing corresponding to the through position of the lever, and a protective cover is provided between the through hole and the lever.

[0020] By adopting the above technical solution, the protective cover structure forms a dual protective barrier against dust and liquid intrusion. The protective cover can effectively enclose the movable gap between the lever and the through hole, dynamically preventing fine particles and droplets from entering the casing through the gap and contaminating the circuit board or switch contacts. This design greatly enhances the product's adaptability in humid or dusty environments. For products like hair clippers that are easily exposed to hair and moisture, it significantly improves the reliability and safety of long-term use, reduces malfunctions caused by internal contamination, and extends the product's lifespan.

[0021] Furthermore, the protective shield is made of elastic material to serve as a linear elastic element.

[0022] By adopting the above technical solution and setting the protective cover as an elastic material, the protective cover can not only protect against dust and foreign objects from entering the machine housing, but also play a role in the elastic reset of the lever. This achieves two goals at once, effectively optimizes the product structure, and saves production costs.

[0023] A toggle switch includes a hair clipper housing, a tactile switch and a lever disposed within the housing, the tactile switch including an acceleration switch and a deceleration switch having their own rebound force, the lever passing through the housing and rotatably connected to the housing, the lever being configured to be tossed from outside the housing to swing around its rotation point and trigger the acceleration switch and deceleration switch, and when the external force on the lever is removed, the rebound force of the acceleration switch or deceleration switch drives the lever to reset.

[0024] By adopting the above technical solution, it has the following effects: This structure eliminates the need for independently set linear elastic reset elements (such as torsion springs, compression springs, etc.) in traditional lever switches, effectively reducing the number of parts and simplifying the overall structural layout inside the housing. This not only reduces the material cost and mold complexity of the product, but also shortens the assembly process due to the reduction of parts, thereby significantly improving production efficiency and reducing manufacturing costs.

[0025] By omitting the independent elastic element, the process of installing tiny springs in a narrow space is avoided, eliminating the assembly difficulties, spring displacement or detachment risks that may exist in this step, making product assembly simpler and faster. At the same time, reducing the number of parts also reduces the probability of machine failure due to the failure of additional components, thereby improving the structural reliability and long-term stability of the product.

[0026] The two major functions of "circuit triggering" and "mechanical reset" are highly integrated into a single component, the tactile switch. After the external force is removed, the reset power of the lever comes directly from the rebound of the internal structure of the pressed tactile switch. The power transmission path is short and there are no intermediate links, which ensures that the reset action is more rapid and direct, and realizes the optimization and integration of component functions.

[0027] A hair clipper, including the aforementioned toggle switch.

[0028] Compared with the prior art, the advantages of this utility model are:

[0029] This invention allows for direct speed control via the swing of a lever, eliminating the need for traditional complex button mechanisms. This design integrates a tactile switch, lever, and linear elastic element into a compact unit, greatly simplifying the internal structure of the product, reducing the number of parts and assembly steps, and effectively lowering production costs.

[0030] The use of linear elastic elements in this invention provides a reliable and consistent reset function, ensuring accuracy and feedback in every operation. Furthermore, since the acceleration and deceleration functions are integrated into a single lever, the number of button holes on the housing can be reduced, minimizing the channels for external contaminants to enter the housing. This fundamentally improves the product's dust and water resistance and overall reliability, extending its service life. The hair clipper's speed can be adjusted simply by moving it up and down, making it more convenient and user-friendly. Attached Figure Description

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] Example 1:

[0051] Reference Figure 1 and 2A toggle switch is adaptable to any product that requires switching, gear adjustment, or other function adjustment. Taking a hair clipper as an example, the switch includes a toggle 3, a tactile switch 5, and a linear elastic element mounted on the housing 1 of the hair clipper. The tactile switch 5 includes an acceleration switch 51 and a deceleration switch 52. The toggle 3 passes through the housing 1 and is rotatably connected to the housing 1. The toggle 3 is configured to be toggled from outside the housing 1 to selectively trigger the acceleration switch 51 or the deceleration switch 52 after swinging around its rotation point, thereby realizing the acceleration or deceleration adjustment of the hair clipper. The toggle 3 is elastically connected to the housing 1 through the linear elastic element to provide an elastic restoring force after the toggle 3 swings.

[0052] In this embodiment, the tactile switch 5 includes an acceleration switch 51 and a deceleration switch 52. When its lever 3 is moved, it realizes the acceleration or deceleration function of the hair clipper. It can be imagined that when the tactile switch 5 is a other function switch, triggering the corresponding tactile switch 5 can activate other functions of the hair clipper. The tactile switch 5 in this embodiment is not limited to the acceleration switch 51 or the deceleration switch 52.

[0053] In this embodiment, the speed adjustment function of the hair clipper can be directly controlled by swinging a lever 3, eliminating the need for the traditional complex button structure. This design integrates the tactile switch 5, lever 3, and linear elastic element into a compact unit, which greatly simplifies the internal structure of the product, reduces the number of parts and assembly steps, and effectively reduces production costs.

[0054] In this embodiment, the use of linear elastic elements provides a reliable and consistent reset function, ensuring the accuracy and feedback of each operation. At the same time, since the acceleration and deceleration functions are integrated into a lever 3, the number of button holes on the housing 1 can be reduced to reduce the channels for external contaminants to enter the housing 1, fundamentally improving the product's dustproof and waterproof capabilities and overall reliability, extending its service life. Meanwhile, the hair clipper's speed can be adjusted simply by moving it up and down, making it more convenient for users and more in line with their operating habits.

[0055] In this embodiment, the hair clipper includes products such as electric clippers and razors, and its general shape can be cuboid, cube, cylinder, disc, ellipse, or other shapes. In this embodiment, refer to... Figure 1 Taking the hair clipper as a cuboid as an example, the plane where the lever 3 is located on the housing 1 is taken as the front end face. The lever 3 passes through the front end face of the housing 1 along the thickness direction of the housing 1 and is rotatably connected to the inside of the housing 1. Thus, the lever 3 can be moved from the outside of the housing 1 so that the part located inside the housing 1 can trigger the corresponding tactile switch 5.

[0056] It should be noted that because hair clippers need to be held by the user, the actual product has a corresponding curved surface. Other shapes such as cuboids, cubes, cylinders, discs, and ellipses referred to in this article are only close to the shape in terms of overall appearance. For example, cuboids are not limited to the literal shape of a square prism with regular edges. The cuboid razor is actually a structure that is close to a cuboid with a curved surface.

[0057] In this embodiment, the direction of the lever 3 is parallel or nearly parallel to the front end face of the housing 1. Preferably, the direction of the lever 3 is set along the height direction of the housing 1. In this way, when a person holds the hair clipper, they only need to push the lever 3 up and down along the height direction of the housing 1 with their thumb to adjust the speed of the hair clipper. The operation is more convenient and conforms to the user's usage habits.

[0058] It is conceivable that in this embodiment, the direction of the lever 3 can also be set along the width direction of the housing 1, that is, the lever 3 can be moved left and right by the thumb, or the lever 3 can be moved in any direction along the front end face of the housing 1, and is not limited to the height direction of the lever 3. The following embodiments all take the lever 3 being moved along the height direction of the housing 1 as an example to illustrate each embodiment.

[0059] In this embodiment, refer to Figure 3 and 4 A through hole 131 is provided on the upper end face of the housing 1. The lever 3 is correspondingly inserted into the through hole 131 as a specific rotational connection between the lever 3 and the housing 1. Two rotating shafts 33 are provided in the middle of the lever 3 along the width direction of the housing 1. The corresponding shaft hole 132 is provided on the inner wall of the housing 1 located at the lower end of the through hole 131 and along the width direction of the housing 1. The lever 3 is rotatably connected to the shaft hole 132 through the rotating shafts 33, so that the lever 3 can move up and down along the upper end face of the housing 1 within the through hole 131, thereby triggering the corresponding tactile switch 5.

[0060] In this embodiment, the direction of the lever 3 being parallel or nearly parallel to the upper surface of the housing 1 is limited based on the general direction. In reality, since the middle part of the lever 3 is rotatably connected to the housing 1 through the pivot 33, when the lever 3 is moved, the lever 3 swings in an arc around the pivot 33. With this moving method, the lever 3 only needs to swing within a small range to trigger the acceleration switch 51 or the deceleration switch 52 through the lower end of the lever 3. This not only makes it convenient for the user to operate with their thumb, but also allows the through hole 131 on the housing 1 to be designed to be smaller, effectively reducing the risk of foreign objects entering the housing 1 through the through hole 131, and also making the product surface more aesthetically pleasing.

[0061] Specifically, refer to Figure 5 and6 The lower end of the lever 3 is connected to the housing 1 through a linear elastic element. The linear elastic element is located inside the housing 1 along the thickness direction. Under normal conditions, the lever 3 is in the middle position of the through hole 131 under the elastic action of the linear elastic element. When the lever 3 is moved up and down along the height direction of the housing 1, the lever 3 swings around the rotating shaft 33, which causes the linear elastic element to bend and touch the corresponding tactile switch 5. When the external force is removed, the linear elastic element resets and drives the lever 3 to reset to the initial position. This process is repeated to achieve the acceleration or deceleration adjustment of the hair clipper.

[0062] In this embodiment, refer to Figure 6 , 7 The acceleration switch 51 and deceleration switch 52 are generally integrated on the circuit board 9, while the lever 3 is installed at the upper end of the circuit board 9. In order to facilitate the triggering of the corresponding tactile switch 5 when the lever 3 is turned, a contact block 32 is provided at the bottom of the lever 3. The contact block 32 extends along the height direction of the housing 1 to both sides of the lever 3. In this way, when the lever 3 is turned, it can touch the acceleration switch 51 or the deceleration switch 52 through the contact block 32 to realize the acceleration and deceleration function of the hair clipper.

[0063] In this embodiment, as a specific example of a linear elastic element, it can be any one of spring 4, compression spring, elastic rubber, and elastic paddle, as long as it can provide elastic restoring force for the lever 3 after being moved. It may be other elastic elements.

[0064] In this embodiment, taking the linear elastic element as spring 4 as an example, in order to facilitate the assembly between lever 3 and housing 1, mounting posts 34 are provided on the inner wall of housing 1 and the lower end of lever 3. Spring 4 is correspondingly sleeved on mounting posts 34, thereby enabling quick positioning of spring 4, housing 1 and lever 3.

[0065] Based on different embodiments of linear elastic elements, the fixing methods between the linear elastic element, housing 1 and lever 3 are different. For example, when the linear elastic element is an elastic plate, it can be connected to the housing 1 and lever 3 by means of screwing, snap-fitting, etc.

[0066] In this embodiment, refer to Figure 5 and 6As a specific embodiment of the lever 3, the lever 3 includes a handle 31 extending out of the front end face of the housing 1. Two protrusions 35 are provided at its lower end along the width direction of the housing 1. A mounting post 34 is provided at the lower end of the protrusions 35 along the thickness direction of the housing 1. A rotating shaft 33 is provided on the side of the protrusions 35 along the width direction of the housing 1. The aforementioned contact block 32 can be provided at the lower end of the two levers 3 and between the two protrusions 35. Of course, it can be imagined that for the specific structural form of the lever 3, as long as it is convenient for the lever 3 to be elastically connected to the housing 1 through a linear elastic element, for the lever 3 to be rotatably connected to the housing 1, and for the contact block 32 to be conveniently set so that when the user moves the handle 31, the contact block 32 can be driven to trigger the tactile switch 5, the lever 3 can also be other shapes or structures, which will not be elaborated here.

[0067] In this embodiment, as a specific embodiment of the casing 1, refer to... Figure 2 It includes a bottom shell 11, an inner shell 12, and a top shell. The inner shell 12 is embedded inside the bottom shell 11, and the top shell 13 covers the bottom shell 11 so that the three shells are combined. The inner shell 12 has a placement groove inside for placing components such as the battery of the hair clipper. The circuit board 9 is correspondingly located between the inner shell 12 and the top shell. The circuit board 9 has a clearance notch corresponding to the position of the protrusion 35 so that the protrusion 35 can pass through the clearance notch and is connected to the mounting post 34 on the inner shell 12 through the spring 4. The acceleration switch 51 and the deceleration switch 52 are correspondingly located at the positions of the two clearance notches on the circuit board 9.

[0068] Example 2:

[0069] In the above embodiments, the reset of lever 3 relies on the elastic force of a linear elastic element. This embodiment provides another embodiment of the lever 3 switch, which omits the elastic reset element and relies solely on the characteristic of the tactile switch 5 to spring back after being pressed to reset lever 3. This method has the following advantages:

[0070] This structure eliminates the need for independently set linear elastic reset elements (such as torsion springs and compression springs) in traditional lever 3 switches, effectively reducing the number of parts and simplifying the overall structural layout inside the housing 1. This not only reduces the material cost and mold complexity of the product, but also shortens the assembly process due to the reduction of parts, thereby significantly improving production efficiency and reducing manufacturing costs.

[0071] By omitting the independent elastic element, the process of installing the tiny spring 4 in a narrow space is avoided, eliminating the assembly difficulties, displacement or detachment of the spring 4 that may exist in this step. This makes the product assembly simpler and faster. At the same time, reducing the number of parts also reduces the probability of the whole machine failing due to the failure of additional components, thereby improving the structural reliability and long-term stability of the product.

[0072] The two major functions of "circuit triggering" and "mechanical reset" are highly integrated into a single component, the tactile switch 5. After the external force is removed, the reset power of the lever 3 comes directly from the rebound of the internal structure of the pressed tactile switch 5. The power transmission path is short and there are no intermediate links, which ensures that the reset action is more rapid and direct, and realizes the optimization and integration of component functions.

[0073] In this embodiment, the tactile switch 5 includes micro switches or other switches. As long as it can trigger the corresponding opening tube after being squeezed by the contact block of the lever 3 and reset the lever 3 after the external force of the lever 3 is removed, the tactile switch 5 can also be other types of switches, which will not be elaborated here.

[0074] In this embodiment, since the rebound stroke of the tactile switch 5 is limited, the rotation angle of the lever 3 along the pivot 33 on the housing 1 can be made smaller, making it more convenient for the user to operate the lever 3. At the same time, the opening area of ​​the through hole 131 on the housing 1 can also be made smaller, which can further reduce the entry of external foreign objects into the housing 1 through the through hole 131, greatly improving the product's dustproof and foreign object-proof capabilities.

[0075] Based on the above embodiments, referring to Figure 3 To prevent foreign objects from entering the housing 1 through the through hole 131, a protective cover 2 is provided between the through hole 131 and the lever 3. Specifically, the protective cover 2 has an opening 21, and the lever 3's handle 31 passes through the opening 21 and protrudes from the surface of the housing 1. In this way, the protective cover 2 forms a double protective barrier against dust and liquid intrusion. The protective cover 2 can effectively enclose the gap between the lever 3 and the through hole 131, dynamically preventing fine particles and droplets from entering the housing 1 through the gap and contaminating the circuit board 9 or the tactile switch. This design greatly enhances the product's adaptability in humid or dusty environments. For a product like a hair clipper that is easily exposed to hair and moisture, it significantly improves the reliability and safety of its long-term use, reduces malfunctions caused by internal contamination, and extends the product's lifespan.

[0076] As a specific embodiment of the protective cover 2, it can be made of flexible material, such as rubber, nylon, or flexible plastic, or it can be made of rigid material, such as hard plastic or metal. As long as the protective cover 2 can shield the through hole 131 when the lever 3 is turned, the protective cover 2 can also be made of other materials or shapes.

[0077] In this embodiment, the flexible material of the protective cover 2 can be a rigid elastic material with flexibility, such as rubber or silicone, or it can be a simple flexible material, such as flexible plastic or nylon cloth.

[0078] Example 3:

[0079] Based on the above embodiments, for the reset of the lever after its movement, Embodiment 1 uses a tactile switch + linear elastic element, while Embodiment 2 only uses the self-rebound characteristic of the tactile switch 5 for reset. Based on this, a third reset method for the lever 3 is provided:

[0080] Specifically, the aforementioned protective cover 2 can be made of elastic material (rubber, elastic nylon, silicone). By utilizing the elastic properties of the material itself, the protective cover 2 can provide elastic restoring force for the lever 3 after it is turned. The advantage of this method is that by making the protective cover 2 an elastic material, it can not only protect against dust and foreign objects from entering the housing, but also provide elastic restoring force for the lever. This achieves two goals at once, effectively optimizing the product structure and saving production costs.

[0081] As a specific method for resetting the lever, this embodiment 3 can be used alone or in combination with embodiments 2 and 3. When the three embodiments are used in combination (the three-way combination means that the lever reset relies on: elastic protective cover 2 + linear elastic element + tactile switch), the trigger feel after the lever is moved and the timeliness and effectiveness of the lever's rebound can be effectively improved. This avoids the situation where the lever is not reset properly or not in time after being moved for a long time, greatly improving the user experience.

[0082] Based on the above embodiments, taking a hair clipper as an example, refer to... Figure 1 Since this is not a major utility model point of this application, only the key components are briefly introduced. The shaver includes a battery, a motor 6, a reciprocating drive, a moving blade head 7, and a fixed blade head 8. The motor 6 is located at the upper end of the housing 1, and its output end drives a reciprocating drive head 61. The reciprocating drive head 61 drives the moving blade head 7 to reciprocate on one side of the fixed blade head 8. The fixed blade head 8 is fixedly installed at the upper end of the housing 1. The battery provides power to the motor 6 and electronic components such as the circuit board 9.

[0083] In this embodiment, the circuit board 9 can be screwed onto the bottom of the housing 13, and the corresponding lever 3 is also rotatably mounted on the housing 13. The advantage of this is that by mounting both on the housing 13, the sensitivity of the lever 3 when adjusting the speed is ensured, and excessive assembly tolerances are avoided, which could lead to poor sensitivity or even failure of the lever 3 when adjusting the speed, thus affecting the user experience.

[0084] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
