Description

Technical Field

[0001] This utility model relates to the field of shavers, and more specifically to a dual-switch shaver. Background Technology

[0002] Current shavers have a single switch, which users must use to adjust the shaver's operating mode, intensity level, or stop shaving. This can be inconvenient and lack of intuitiveness. For example, during shaving, switching from one mode to another or adjusting the shaving intensity might require turning the shaver off and on again in a specific combination, which can be cumbersome and reduce the user experience.

[0003] During shaving, if an emergency occurs, such as abnormal vibration or noise from the shaver, or if the user feels discomfort, the user may want to immediately disconnect the power to stop the shaver from operating. However, if there is only one switch with multiple functions, accidental activation of other functions may prevent the power from being disconnected quickly and accurately, thus increasing safety hazards.

[0004] Moreover, if there is only one switch, it is difficult to provide users with a wide variety of functions, and it cannot meet the shaving needs of different users in different situations, thus limiting the performance of the razor and the expansion of its usage scenarios.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0039] refer to Figure 1 and Figure 2 This utility model provides a dual-switch shaver, including a blade holder 1 and a handle 3 connected vertically, and an operating component disposed on the outside of the handle 3; the handle 3 includes a first side 31, a second side 32, a third side 33 and a fourth side 34 connected in a circumferential direction. The first side 31 and the third side 33 are symmetrically arranged along the central axis of the handle 3 and decrease in size towards one side of the handle 3. The second side 32 and the fourth side 34 are respectively connected to the adjacent ends of the first side 31 and the third side 33; the operating component includes a switch component 311 and a shift component 331 correspondingly installed on the first side 31 and the third side 33. The switch component 311 and the shift component 331 are symmetrically arranged on both sides of the central axis of the handle 3.

[0040] In this embodiment, during shaving, the user can quickly start the shaver and switch gears in real time according to the beard condition, achieving continuous and smooth shaving operation, effectively shortening the shaving preparation and mode switching time, and improving shaving efficiency; the first side 31 and the third side 33 of the handle 3 are symmetrically arranged along the central axis of the handle 3 and decrease in size towards one side of the handle 3, so that the switch component 311 and the gear shifting component 331 are symmetrically arranged on both sides of the central axis of the handle 3, so that the user can easily touch and operate the switch component 311 and the gear shifting component 331 without adjusting the hand posture or position when holding the shaver with one hand.

[0041] Specifically, the first side portion 31 and the third side portion 33 are symmetrically arranged along the central axis of the handle 3 and taper towards one side of the handle 3. The second side portion 32 and the fourth side portion 34 are respectively connected to the adjacent ends of the first side portion 31 and the third side portion 33. In this way, the handle 3 not only conforms to ergonomic principles, better fits the user's palm, and provides a comfortable grip, but also provides a reasonable layout for the installation of the operating components, ensuring that the user can easily operate each component during use.

[0042] The operating components include a switch component 311 and a shift component 331. The switch component 311 controls the start and stop of the shaver, allowing the user to easily start or stop the shaver while holding it, and has a good anti-accidental touch function. The shift component 331 is used to adjust the shaver's working mode, such as different shaving intensities and speed levels. The operation is simple and intuitive, allowing users to flexibly adjust the shaving mode according to their individual beard density and shaving preferences to meet diverse shaving needs. Preferably, the shift switch is equipped with an adaptive adjustment mode. This adaptive adjustment mode dynamically adjusts the shaver's working parameters in real time based on skin contact pressure sensor data and motion state detection data. For example, it automatically adjusts the shaving mode according to the user's shaving habits and preferences, or automatically detects the density and hardness of the beard during shaving, thereby automatically adjusting the shaver's shaving intensity to provide the user with a more personalized shaving experience.

[0043] Secondly, the switch component 311 and the shifting component 331 are symmetrically arranged on both sides of the central axis of the handle 3, allowing the user to easily operate the switch component 311 and the shifting component 331 without adjusting hand posture or position when holding the shaver with one hand. Thirdly, the first side 31 and the third side 33 of the handle 3 are symmetrically arranged along the central axis of the handle 3 and taper towards one side of the handle 3, resulting in a smaller cross-section of the handle 3. This allows for a better fit to the finger curves when holding the handle 3, enhancing grip stability and comfort. Whether the user uses it for extended periods or operates at a specific angle, a comfortable grip is maintained, reducing hand fatigue.

[0044] Furthermore, this application separates the switch component 311 and the shifting component 331, avoiding potential problems such as misoperation, poor contact, or component damage when a single switch performs multiple function switching tasks. Simultaneously, the symmetrical arrangement of the switch component 311 and the shifting component 331 on both sides of the handle 3 enhances the overall stability of the shaver, making it less susceptible to damage from accidental collisions or drops during use, further ensuring product reliability and safety, and reducing maintenance costs and risks for users. It is worth noting that the shaver holder 1 is a prior art feature of shavers, and this application will not elaborate further or limit it, as long as it enables the shaving function.

[0045] Further, refer to Figure 3 and Figure 6 It also includes a first protective shell 4, which is sleeved on the outside of the handle 3. The first protective shell 4 has a mounting groove 401 at the corresponding position of the operating component. The mounting groove 401 is suitable for installing the switch component 311 and the shift component 331.

[0046] In this embodiment, the first protective shell 4 not only provides additional protection for the handle 3 and the operating components to prevent the shaver from being damaged by accidental collisions or scratches during use or storage, but also ensures that the switch component 311 and the shift component 331 can be securely installed inside the first protective shell 4 without affecting their normal operation function, ensuring that the user can smoothly switch on and off and adjust the mode.

[0047] Specifically, refer to Figure 4 Both the switch component 311 and the shift component 331 include a pressing frame 3111, a pressing key 3112, and a button 3113. The button 3113 is disposed on the first side 31 and the third side 33. The outer edge of the pressing frame 3111 is adapted to abut against the first protective shell 4 and the handle 3. The pressing frame 3111 has an axially extending groove that matches the button 3113. The pressing key 3112 is movably disposed in the moving groove and adapted to press the button 3113. More specifically, the button 3113 is disposed on the first side 31 and the third side 33, located at the position where the user's fingers naturally rest, making it easy for the user to reach and operate when holding the shaver. The outer edge of the pressing frame 3111 perfectly matches the gap between the first protective shell 4 and the handle 3, and can be firmly abutted against the two, playing a role in fixing and supporting, ensuring the stability of the entire operating component during use, preventing loosening or displacement due to external forces, thereby ensuring the accuracy and reliability of operation.

[0048] A movable groove, precisely matching the button 3113, is axially provided on the pressing frame 3111. This movable groove provides a precise movement path for the pressing button 3112, allowing it to move smoothly within the groove and preventing jamming or misalignment during operation. When the user presses the pressing button 3112, it moves within the movable groove and appropriately presses the button 3113, thereby triggering the corresponding switch or gear shift operation to achieve functions such as starting, stopping, or switching modes of the shaver. The top surface of the pressing button 3112 does not exceed the top surface of the movable groove to prevent accidental activation of the pressing button 3112 while holding the shaver.

[0049] Furthermore, a second side portion 32 is disposed at the beginning of the first side portion 31 and the third side portion 33. A battery assembly 306 is disposed inside the second side portion 32, and a heat dissipation portion is disposed at the corresponding position of the battery assembly 306. A corresponding heat dissipation groove 41 is disposed on the first protective shell 4, and the heat dissipation groove 41 is adapted to expose the heat dissipation portion. A fourth side portion 34 is disposed at the end of the first side portion 31 and the third side portion 33. A display assembly 307 is disposed inside the fourth side portion 34. A display portion is formed on the second side portion 32 corresponding to the display portion. A corresponding display groove 42 is disposed on the first protective shell 4, and the display groove 42 is adapted to expose the display portion.

[0050] Specifically, the second side portion 32 is located at the beginning of the first side portion 31 and the third side portion 33, where the second side portion 32 is at its longest. Therefore, a battery assembly 306 is located inside the second side portion 32. Considering that the battery assembly 306 generates heat during operation, a heat dissipation section is specially provided at the corresponding position of the battery assembly 306 on the second side portion 32 to ensure the performance and lifespan of the battery assembly 306, as well as the overall safety of the shaver. This heat dissipation section uses a highly efficient heat dissipation material, which can quickly conduct and dissipate the heat generated by the battery, effectively reducing the temperature of the battery assembly 306 and maintaining it within a suitable operating temperature range. The first protective shell 4 has a heat dissipation groove 41 at the corresponding position. The shape and size of the heat dissipation groove 41 precisely match the heat dissipation section, ensuring that the heat dissipation section is fully and appropriately exposed. This not only ensures heat dissipation but also takes into account the overall appearance and aesthetics of the product. Through the heat dissipation groove 41, external air can smoothly contact the heat dissipation section, further promoting heat dissipation, thereby forming a good heat dissipation cycle and ensuring the stability and reliability of the shaver during long-term use.

[0051] A fourth side portion 34 is located at the tail end of the first side portion 31 and the third side portion 33. Its inner side is equipped with a display component 307 for displaying various operating status information of the shaver to the user, such as battery level, shaving mode, and fault indications. The display component 307 forms a corresponding display section on the second side portion 32, allowing the display section to clearly display relevant information for easy viewing during use. The first protective shell 4 has a display slot 42 at a corresponding position. The size and shape of the display slot 42 match the display section, appropriately exposing it. Thus, even when the shaver is covered by the first protective shell 4, the user can clearly see the information displayed, better understand the shaver's operating status, and make timely adjustments.

[0052] Preferably, refer to Figure 2 Both the second side portion 32 and the fourth side portion 34 include a pair of decreasing segments 321 and a parallel segment 322; the first ends of the pair of decreasing segments 321 are respectively connected to the first side portion 31 and the third side portion 33 and are adapted to decrease and shrink away from the first side portion 31 and the second side portion 32, and the parallel segment 322 is connected to the end of the decreasing segments 321.

[0053] In this embodiment, the decreasing contraction of the decreasing segment 321 makes the shape of the handle 3 more streamlined and better adaptable to the size and shape of different users' hands, providing a more personalized grip experience. The parallel segment 322 connects to the end of the decreasing segment 321, forming a relatively flat surface that provides a stable support point for the user's fingers, further enhancing the stability of the grip.

[0054] Specifically, both the second side 32 and the fourth side 34 include a pair of decreasing segments 321 and a parallel segment 322, and the parallel segments 322 of the second side 32 and the fourth side 34 are parallel to each other, so that the cross-section of the handle 3 is octagonal. This not only has a unique aesthetic appeal, but also provides more contact points. When the handle 3 contacts the hand, it can provide a relatively large contact area, so that the user can hold the razor more firmly and reduce the possibility of slippage.

[0055] Furthermore, the first side 31 and the third side 33 are symmetrical along the central axis of the handle 3 and gradually decrease in size towards one side. The first ends of a pair of decreasing segments 321 are respectively connected to the first side 31 and the third side 33 and are adapted to gradually decrease in size towards the side away from the first side 31 and the second side 32. Each side of the handle 3 can serve as a support point, allowing the user to find a comfortable and stable position regardless of how they hold it. When the hand holds the handle 3, each side can correspond to the contact area of ​​different fingers, allowing the fingers to be naturally distributed on each side, making the force on the hand more even during the grip and reducing fatigue caused by excessive local pressure.

[0056] In addition, the octagonal structure can increase the structural strength of the handle 3, making it more durable and able to withstand various pressures and impacts in daily use. This allows the handle 3 to form a concave shape similar to the natural grip of the hand, similar to the design principle of a pistol grip, which allows the palm to fit the handle 3 better and increases the stability when holding it.

[0057] Further, refer to Figure 5 The handle 3 also includes a drive assembly 304, which is coaxially located in the center of the handle 3 and positioned between the display assembly 307, the switch assembly 311, the shift assembly 331, and the battery assembly 306.

[0058] In this embodiment, the drive component 304 is coaxially disposed in the center of the handle 3 and is located between the display component 307, the switch component 311, the shift component 331 and the battery component 306, making the internal structure of the shaver more compact and reasonable, with higher space utilization, ensuring that the various components can work together efficiently, while maintaining the overall balance and stability of the handle 3.

[0059] Specifically, the drive assembly 304 typically includes a motor, a gear transmission system, and a cutter head drive mechanism. Further details are omitted here. The drive assembly 304 is coaxially positioned at the center of the handle 3, meaning its axis coincides with the central axis of the handle 3. The display assembly 307, switch component 311, shift component 331, and battery assembly 306 are located at four radial angles of the drive assembly 304. Correspondingly, the handle 3 is equipped with a first circuit board 301, a second circuit board 302, a third circuit board 303, a fourth circuit board 305, and a drive assembly 304. The first circuit board 301 corresponds to the first side 31 and is connected to the switch component 311. The second circuit board 302 corresponds to the second side 32 and is connected to the display component 307. The third circuit board 303 is disposed parallel to the bottom end face of the handle 3. The fourth circuit board 305 corresponds to the fourth side 34 and is connected to the shift component 331. The first circuit board 301, the second circuit board 302, the fourth circuit board 305, and the battery assembly 306 are vertically inserted into the third circuit board 303. The battery assembly 306, the first circuit board 301, the fourth circuit board 305, and the second circuit board 302 are arranged around the drive assembly 304 in sequence around the handle 3.

[0060] Further, refer to Figure 6 The handle 3 includes an upper handle 35 and a lower handle 36. The bottom of the upper handle 35 is provided with a plurality of first latching blocks 351, and the first latching blocks 351 are provided with first abutting grooves 352. The outer side of the lower handle 36 is provided with a plurality of first latching grooves 361, and the first latching grooves 361 are provided with first abutting blocks 362. The first latching blocks 351 are adapted to be latched and installed in the first latching grooves 361. The inner sidewall of the first protective shell 4 is adapted to abut against the outer sidewall of the first latching blocks 351.

[0061] In this embodiment, the upper handle 35 and the lower handle 36 are connected by a snap-fit, which not only makes operation simple and facilitates the assembly and maintenance of the shaver, but also ensures the stability of the handle 3 during use and prevents it from loosening or separating due to external forces.

[0062] Specifically, the bottom of the upper handle 35 is provided with several first snap blocks 351, each with a first abutment groove 352. The outer side of the lower handle 36 is provided with several matching first snap grooves 361, each with a first abutment block 362. During assembly, the guide surface of the first snap block 351 slides along the guide surface of the first abutment block 362 and moves downwards, deforming. When the first snap block 351 reaches the position of the first snap groove 361, it abuts against the first snap groove 361, and the first abutment block 362 abuts against the first abutment groove 352, forming a stable snap connection structure. The inner wall of the first protective shell 4 is adapted to abut against the outer walls of the first snap block 351 and the first abutment block 362 located within the first snap groove 361, providing additional fixation and protection for the fixed connection between the upper handle 35 and the lower handle 36 when the first protective shell 4 is fitted onto the outer side of the handle 3. This not only strengthens the bond between the first protective shell 4 and the handle 3, but also effectively prevents external factors such as dust and moisture from penetrating the internal structure of the handle 3, extending the shaver's lifespan. At the same time, the first protective shell 4 also makes the shaver's overall appearance cleaner and more aesthetically pleasing, enhancing the product's overall quality.

[0063] It is worth noting that a first charging component 308 is provided on the side wall of the lower handle 36, and a first charging terminal 309 is provided at the bottom of the lower handle 36. The first charging component 308 and the battery component 306 are located on the same side of the handle 3 and use a universal Type-C interface. The first charging terminal 309 is located at the bottom of the lower handle 36, allowing users to charge the shaver simply by placing it on the wireless charging base, eliminating the need to plug and unplug a charging cable and reducing the risk of wear and damage to the charging interface. The first charging terminal 309 can be designed as either magnetic or contact-type. A magnetic first charging terminal 309 can automatically attach and connect to the charging base, while a contact-type first charging terminal 309 connects via metal contacts.

[0064] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
