Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a shaver. Background Technology

[0002] Many shavers on the market lack adjustable blade speed and reversible rotation, resulting in a poor shaving experience. Because facial hair varies greatly across different areas of the face—for example, chin hair is thick and coarse, while upper lip hair is fine and sparse—if the shaver's blade lacks adjustable speed and reversible rotation, it can only operate with the blade stationary. When the stationary blade pushes against the skin, the hairs are pressed down by the blade, preventing the lifting of flat hairs and significantly reducing shaving efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a shaver that addresses the problem of the lack of speed and direction adjustment in shaver blades.

[0004] A razor includes: a housing assembly having a receiving cavity; a drive assembly disposed on the housing assembly and located within the receiving cavity; a transmission assembly disposed on the housing assembly and located within the receiving cavity, the transmission assembly including a first transmission assembly and a second transmission assembly, both the first and second transmission assemblies being pulsatorically connected to the drive assembly; a foil assembly having a shaving cavity and a hair inlet communicating with the shaving cavity, the foil assembly being disposed on the housing assembly and pulsatorically connected to the first transmission assembly, the first transmission assembly capable of driving the foil assembly to rotate in a first direction according to a first mode and capable of driving the foil assembly to rotate in a second direction according to a second mode, the second direction being opposite to the first direction; and an inner blade assembly pulsatorically connected to the second transmission assembly and abutting against the side of the foil assembly having the hair inlet.

[0005] The above-disclosed shaver features a foil assembly that, driven by a first transmission component, rotates in opposite directions in two modes: a first mode and a second mode. This, combined with an inner blade assembly that abuts against the foil assembly, creates a bidirectional, staggered cutting motion. In the first mode, the foil assembly rotates clockwise while the inner blade assembly operates synchronously. The cutting angle formed by the foil and inner blades precisely cuts beard hairs growing perpendicular to the foil surface. In the second mode, the foil assembly rotates counter-clockwise, re-establishing the cutting angle with the inner blades to target angled, curled beard hairs. This dynamic cutting mechanism acts like a multi-dimensional capture network, ensuring that even the hard-to-reach roots of beard hairs are fully exposed and cut during the bidirectional movement of the foil. After the beard enters the shaving chamber through the inlet, the bidirectional rotation of the foil assembly creates a high-frequency, multi-angle cutting environment within the chamber. Compared to traditional one-way shavers, this product achieves multi-directional cutting of the beard during a single shave, significantly improving the cleanliness and efficiency of the shave. Furthermore, it reduces repeated shaving due to stubble residue, saving users time and effectively reducing discomfort such as burning and redness caused by excessive friction. Even users with sensitive skin can enjoy a comfortable and smooth shave. The housing assembly's cavity design provides stable mounting space for the drive and transmission components, ensuring a compact internal structure and smooth operation, effectively reducing vibration and noise during operation. In addition, the flexible transmission method of the foil assembly and the first transmission assembly allows the shaver to better conform to the facial contours during use, easily handling complex areas such as the chin and neck, making operation more flexible and convenient.

[0006] In one embodiment, when the first transmission component drives the foil assembly to rotate in a first direction according to a first mode, the rotational speed of the foil assembly is a first constant speed; when the first transmission component drives the foil assembly to rotate in a second direction according to a second mode, the rotational speed of the foil assembly is a second constant speed. By utilizing the first transmission component to drive the foil assembly to rotate at the first constant speed and the second constant speed in two modes respectively, the shaver achieves several key benefits. In terms of shaving performance, the constant speed ensures that the cooperation between the foil assembly and the inner blade assembly remains stable. When the foil assembly rotates in the first direction at the first constant speed, the beard enters the shaving chamber and is subjected to uniform and continuous pulling and cutting forces, avoiding insufficient or excessive pulling of the beard due to speed fluctuations, ensuring that every beard hair is precisely cut. Similarly, the second constant speed allows the foil assembly to handle beards with different growth directions with a stable cutting force when rotating in the opposite direction, effectively improving the cleanliness and evenness of the shave and reducing the problem of incomplete or excessive shaving in certain areas. From a user experience perspective, constant speed operation significantly reduces vibration and noise during shaver operation. The stable speed makes the shaver more comfortable to hold, preventing hand fatigue caused by frequent vibrations, while the reduced operating noise also makes the shaving process quieter and more comfortable.

[0007] In one embodiment, the first constant rotational speed is 30 rpm to 1200 rpm. By setting the first constant rotational speed to 30 rpm to 1200 rpm, the rotational speed range of 30 rpm to 1200 rpm can be adapted to the shaving habits and needs of different users. Users can choose to enjoy a gentle shave at a low speed or use a high speed for a quick shave, meeting diverse usage scenarios and ensuring that the razor can exhibit good shaving performance under various beard conditions and skin types.

[0008] In one embodiment, the second constant speed is 30 rpm to 1200 rpm. By setting the second constant speed to 30 rpm to 1200 rpm, the speed range of 30 rpm to 1200 rpm can be adapted to the shaving habits and needs of different users. Users can choose to enjoy a gentle shave at a low speed or use a high speed for a quick shave, meeting diverse usage scenarios and ensuring that the razor can exhibit good shaving performance under various beard conditions and skin types.

[0009] In one embodiment, the first transmission component is a forward and reverse rotation transmission gear. By designing the first transmission component as a forward and reverse rotation transmission gear, this bidirectional transmission mechanism can change the contact angle and cutting direction between the razor and the beard. Whether the beard grows vertically, obliquely, or curly, it can be fully captured and cut during the forward and reverse rotation of the razor. Compared with unidirectional transmission razors, this significantly improves the cleanliness and efficiency of shaving and reduces the problem of beard residue.

[0010] In one embodiment, when the first transmission component drives the foil assembly to rotate in a first direction according to a first mode, the rotational speed of the foil assembly changes from a first speed to a second speed, where the first speed is greater than or less than the second speed. By utilizing a dynamic speed adjustment mechanism, the shaver is given more flexible and efficient shaving performance. When the transmission component drives the foil assembly to accelerate shaving in the forward direction, that is, the rotational speed gradually increases from the first speed to the second speed, this acceleration mechanism greatly improves the dynamic adaptability of shaving. The lower speed in the initial stage allows the foil assembly to gently conform to the skin, reducing discomfort at the beginning of shaving, especially suitable for starting shaving on sensitive areas such as the chin and neck. As the speed gradually increases, the cutting force of the foil assembly and the inner blade assembly continuously increases, enabling fast and powerful processing of dense beard areas, achieving a smooth transition from gentle start to efficient shaving. This accelerated shaving mode, which starts slowly and then speeds up, avoids the skin irritation that may be caused by high-speed operation at the beginning, and can fully exert shaving efficiency in dense beard areas, significantly shortening shaving time, while also reducing skin damage caused by repeatedly shaving the same area. Forward deceleration shaving, where the rotation speed of the foil assembly gradually decreases from a high initial speed to a lower second speed, offers unique advantages during shaving. At high speed startup, the powerful cutting force quickly handles large areas of beard, efficiently reducing beard length and improving shaving efficiency. As the speed gradually decreases, the foil assembly and inner blade assembly work together more precisely, accurately capturing residual beard hairs and meticulously addressing hard-to-shave areas such as around the lips and Adam's apple. Low-speed operation effectively reduces friction between the foil assembly and the skin, lowering the risk of burning and redness caused by high-speed vibration, making it particularly suitable for users with sensitive skin or fine beards. Furthermore, in deceleration shaving mode, the load on the transmission and foil assemblies gradually decreases, effectively extending the lifespan of each component, reducing mechanical wear caused by prolonged high-speed operation, lowering product maintenance costs, and ensuring long-term stable performance while providing a comfortable shaving experience.

[0011] In one embodiment, when the first transmission component drives the foil assembly to rotate in a second direction according to the second mode, the rotational speed of the foil assembly changes from a third speed to a fourth speed, where the third speed is greater than or less than the fourth speed. By utilizing a dynamic speed adjustment mechanism, the shaver is given more flexible and efficient shaving performance. When the transmission component drives the foil assembly to accelerate shaving in the second mode, that is, the rotational speed gradually increases from the third speed to the fourth speed, this reverse acceleration mechanism can effectively compensate for the cutting blind spots during forward shaving. Since beard hairs grow in different directions, some beard hairs may be difficult to cut completely when shaving forward due to angle issues. However, when accelerating shaving in the reverse direction, the cutting angle between the foil assembly and the inner blade assembly changes. As the speed gradually increases, a new pulling and cutting force can be formed on the remaining beard hairs. At low speed start-up, the foil assembly contacts the skin in a gentle manner, leaving room for adjusting the shaving angle, which is suitable for handling difficult-to-reach areas such as the back of the neck and sideburns. As the speed increases, the powerful cutting force can accurately cut stubborn beard hairs, achieving a thorough shave without dead angles. Simultaneously, during the reverse acceleration process, the contact pressure between the foil assembly and the skin gradually increases, allowing for a better fit to the facial contours and further improving shaving efficiency and cleanliness. The reverse deceleration shaving technique, where the foil assembly's rotation speed gradually decreases from a higher third speed to a fourth speed, also offers significant advantages. At high-speed start-up, the rapidly rotating foil assembly can quickly process a large area of ​​beard hair, rapidly reducing beard density. Near the end of the shave, the rotation speed gradually decreases, allowing the foil assembly to perform a more delicate secondary trimming of the shaving area, ensuring no hairs are missed. For areas with skin folds or uneven surfaces, the low-speed foil provides a better fit, avoiding shaving and pulling caused by high-speed rotation, greatly improving shaving comfort and safety.

[0012] In one embodiment, the foil assembly rotates at an angle of 2 degrees or more according to the first mode. By setting the rotation angle of the first mode to 2 degrees or more, the larger rotation angle allows the foil assembly to better conform to the facial contours. During shaving, for uneven areas of the face, such as the nasolabial folds and jawline, the foil assembly can adjust its angle by rotating at least 2 degrees to more comprehensively cover the beard growth area, reduce blind spots, thereby improving the cleanliness of the shave and preventing beard residue.

[0013] In one embodiment, the foil assembly rotates at an angle of 2 degrees or more in the second mode. By setting the rotation angle of the second mode to 2 degrees or more, the larger rotation angle allows the foil assembly to better conform to the facial contours. During shaving, for uneven areas of the face, such as the nasolabial folds and jawline, the foil assembly can adjust its angle by rotating at least 2 degrees to more comprehensively cover the beard growth area, reduce blind spots, thereby improving the cleanliness of the shave and preventing beard residue.

[0014] In one embodiment, the housing assembly includes a main housing, a support housing, and a charging housing. The support housing is located at one end of the main housing, and the charging housing is located at the other end of the main housing. The main housing, the support housing, and the charging housing together form the receiving cavity. By utilizing the main housing, the support housing, and the charging housing to form the receiving cavity, the shaver offers several significant advantages. The main housing, as the core area, centrally houses key components such as the drive assembly and transmission assembly, providing them with a stable operating space and ensuring efficient collaboration of the internal precision mechanical structure. The support housing, located at one end of the main housing, provides stable support for the front-end shaving components such as the foil assembly and inner blade assembly, ensuring the stability of the shaver head during shaving and preventing shaving performance issues caused by shaking. The charging housing, located at the other end of the main housing, integrates the charging interface, battery, and other charging-related components, enabling independent charging functionality, preventing interference with other components during charging, and facilitating quick identification and use of the charging interface by the user. The main housing, support housing, and charging housing work together to enhance the shaver's overall impact resistance, effectively protecting internal components from damage during daily use or accidental drops and extending the product's lifespan. Furthermore, this enclosed design allows for a more organized internal cable layout, reducing the risk of short circuits and other malfunctions caused by tangled cables.

[0015] In one embodiment, the main housing includes a grip outer shell, a mounting inner shell, and a battery housing. Both the mounting inner shell and the battery housing are disposed on the grip outer shell and located within the receiving cavity. The drive assembly, the transmission assembly, and the inner blade assembly are all disposed on the mounting inner shell. Combining the grip outer shell, mounting inner shell, and battery housing to form the main housing provides significant benefits to the shaver. The grip outer shell resists everyday bumps and impacts, protecting the internal structure. The mounting inner shell, as the base of the internal structure, has a standardized mounting structure that precisely positions the drive assembly, transmission assembly, and inner blade assembly, reducing installation errors and ensuring efficient component operation. Simultaneously, its rational mechanical design effectively disperses operational vibrations, reducing noise and shaking, and improving the shaving experience. The battery housing independently houses the battery, isolating it from other components to prevent heat and electromagnetic interference from affecting performance during charging and discharging. Fire-resistant and insulating materials further ensure battery safety, preventing risks such as short circuits and leakage. The three components work together closely within the housing, creating a compact and orderly spatial layout. This not only enhances the shaver's durability and shaving stability, but the modular design also facilitates the replacement and maintenance of components such as the battery, reducing usage costs and achieving an efficient, safe, and convenient shaving experience.

[0016] In one embodiment, the support housing includes an upper support housing, a lower support housing, and a foil support housing. The lower support housing is disposed on the main housing, the upper support housing is disposed on the lower support housing, the foil support housing is disposed on the upper support housing, and the foil assembly is disposed on the foil support housing. The lower support housing has multiple slots arranged around it. By placing the lower support housing on the main housing, stable support is provided for the upper structure. The upper support housing, mounted on the lower support housing, further enhances the overall stability of the support housing and provides a reliable load-bearing foundation for the foil support housing. The foil support housing can precisely position the foil assembly, ensuring its stability during operation and preventing wobbling or displacement, thereby guaranteeing the accuracy and efficiency of the shaving action. When the shaver experiences localized malfunctions or wear, the multiple slots on the lower support housing allow repair personnel or users to quickly separate the upper and lower support housings, accurately locate the internal foil support housing, foil assembly, and other components for inspection or replacement, significantly reducing repair time and difficulty. Compared to traditional all-in-one structures, this design eliminates the need for complete disassembly, reducing the risk of damage to other components due to excessive disassembly, improving repair efficiency, and lowering maintenance costs. For users seeking personalized cleaning, the upper support shell can be easily removed for deep cleaning of internal components, preventing the accumulation of beard residue, dandruff, etc., from affecting shaving performance and hygiene, thus maintaining the shaver's high efficiency and cleanliness.

[0017] In one embodiment, a battery assembly is also included. The battery assembly comprises a charging device and a battery body. The charging device is disposed on the main housing, which has a charging port. The charging device is positioned opposite the charging port. The battery body is disposed on the main housing, and the battery body and the charging device are electrically connected via a PCB circuit board. By positioning the charging device opposite the charging port, the charging interface is ensured to be precisely positioned and easy to plug and unplug. Users can quickly connect the charging cable without complicated operations, achieving convenient charging. Simultaneously, this design reduces contact problems caused by interface misalignment during charging, effectively improving charging efficiency and shortening charging time. The charging device is independently disposed on the battery housing, physically isolated from other components, preventing heat and electromagnetic interference generated during charging from affecting other precision components inside the shaver, reducing the risk of malfunctions due to electromagnetic compatibility issues. The battery body is also housed within the battery housing, providing it with safety protection to prevent short circuits, leakage, and other situations from affecting other components, ensuring user safety. The battery body is electrically connected to the charging device, enabling efficient and stable power transmission and storage.

[0018] In one embodiment, a control component is also included, comprising a control button and a circuit board. The circuit board is disposed on the housing assembly, and the control button is disposed on the circuit board and passes through the housing assembly. By allowing direct user interaction through the housing assembly, the control button's position and tactile feedback are carefully designed for ergonomics, enabling easy one-handed operation during shaving to control functions such as power on / off, mode switching, and speed adjustment. The circuit board integrates various control chips and circuit modules, precisely regulating the coordinated operation of the drive assembly, transmission assembly, and battery assembly. It intelligently allocates power according to the instructions from the control button, ensuring stable operation of the foil assembly according to preset modes and speeds.

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] The following describes some embodiments of the razor according to the present invention with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 10 As shown, this embodiment discloses a shaver, including: a housing assembly 1, which has a receiving cavity 101; a drive assembly 2, which is disposed on the housing assembly 1 and located in the receiving cavity 101; a transmission assembly 3, which is disposed on the housing assembly 1 and located in the receiving cavity 101, the transmission assembly 3 including a first transmission assembly 31 and a second transmission assembly 32, both of which are pulsatorically connected to the drive assembly 2; a foil assembly 4, which has a shaving cavity 401 and a hair inlet 402 communicating with the shaving cavity 401, the foil assembly 4 is disposed on the housing assembly 1 and pulsatorically connected to the first transmission assembly 31, the first transmission assembly 31 being able to drive the foil assembly 4 to rotate in a first direction according to a first mode and the first transmission assembly 31 being able to drive the foil assembly 4 to rotate in a second direction according to a second mode, the second direction being opposite to the first direction; and an inner blade assembly 5, which is pulsatorically connected to the second transmission assembly 32 and abuts against the side of the foil assembly 4 with the hair inlet 402.

[0042] This application discloses a shaver in which the foil assembly 4, driven by a first transmission assembly 31, rotates in opposite directions in two modes, cooperating with the inner blade assembly 5 to form a bidirectional, staggered cutting action. When the shaver is started, in the first mode, the foil assembly 4 rotates clockwise, and the inner blade assembly 5 operates synchronously. The cutting angle formed by the foil assembly 4 and the inner blade assembly 5 precisely cuts beard hairs growing perpendicular to the foil surface. Switching to the second mode, the foil assembly 4 rotates counterclockwise, re-establishing the cutting angle with the inner blade assembly 5 to target obliquely growing, curled beard hairs. This dynamic cutting mechanism acts like a multi-dimensional capture network, ensuring that even the hard-to-reach roots of beard hairs are fully exposed and cut during the bidirectional movement of the foil. After the beard enters the shaving chamber 401 from the inlet 402, the bidirectional rotation of the foil assembly 4 creates a high-frequency, multi-angle cutting environment within the chamber. Compared to traditional one-way shavers, this product achieves multi-directional cutting of the beard during a single shave, significantly improving the cleanliness and efficiency of the shave. Furthermore, it reduces repeated shaving due to beard residue, saving users time and effectively reducing discomfort such as burning and redness caused by excessive friction on the skin. Even users with sensitive skin can enjoy a comfortable and smooth shave. The housing assembly 1's cavity design provides a stable installation space for the drive assembly 2 and transmission assembly 3, ensuring a compact internal structure and smooth operation, effectively reducing vibration and noise during operation. In addition, the flexible transmission method of the foil assembly 4 and the first transmission assembly 31 allows the shaver to better conform to the facial contours during use, easily handling complex areas such as the chin and neck, making operation more flexible and convenient.

[0043] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines: when the first transmission component 31 drives the foil component 4 to rotate in the first direction according to the first mode, the rotational speed of the foil component 4 is a first constant speed; when the first transmission component 31 drives the foil component 4 to rotate in the second direction according to the second mode, the rotational speed of the foil component 4 is a second constant speed. By utilizing the first transmission component 31 to drive the foil component 4 to rotate at the first constant speed and the second constant speed in the two modes respectively, multiple key functions are brought to the shaver. In terms of shaving effect, the constant speed ensures that the cooperation between the foil component 4 and the inner blade component 5 is always in a stable state. When the foil component 4 rotates in the first direction at the first constant speed, after the beard enters the shaving chamber 401, it will be subjected to uniform and continuous pulling and cutting force, avoiding insufficient or excessive pulling of the beard due to speed fluctuations, and ensuring that every beard hair can be accurately cut. Similarly, the second constant rotation speed allows the foil assembly 4 to maintain a stable cutting force even when rotating in the opposite direction, effectively improving the cleanliness and evenness of the shave and reducing the problem of incomplete or over-shaving in certain areas. From a user experience perspective, constant rotation speed significantly reduces vibration and noise during shaver operation. The stable rotation speed makes the shaver more comfortable to hold, preventing hand fatigue caused by frequent vibrations, while the reduced operating noise makes the shaving process quieter and more comfortable.

[0044] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines the first constant rotation speed as 30 rpm-1200 rpm. By setting the first constant rotation speed to 30 rpm-1200 rpm, the rotation speed range of 30 rpm-1200 rpm can be adapted to the shaving habits and needs of different users. Users can choose to enjoy a gentle shave at a low speed or use a high speed for a quick shave, meeting diverse usage scenarios and enabling the razor to exhibit good shaving performance under various beard conditions and skin types.

[0045] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines the second constant speed as 30 rpm-1200 rpm. By setting the second constant speed to 30 rpm-1200 rpm, the speed range of 30 rpm-1200 rpm can be adapted to the shaving habits and needs of different users. Users can choose a low speed for a gentle shave or a high speed for a quick shave, meeting diverse usage scenarios and ensuring that the razor exhibits good shaving performance under various beard conditions and skin types.

[0046] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first transmission component is a forward and reverse rotation transmission gear. By designing the first transmission component as a forward and reverse rotation transmission gear, this bidirectional transmission mechanism can change the contact angle and cutting direction between the blade and the beard. Whether the beard grows vertically, obliquely, or curly, it can be fully captured and cut during the forward and reverse rotation of the blade. Compared with unidirectional transmission razors, this significantly improves the cleanliness and efficiency of shaving and reduces the problem of beard residue.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that when the transmission component 3 drives the foil component 4 to rotate in the first direction according to the first mode, the rotational speed of the foil component 4 changes from a first speed to a second speed, where the first speed is greater than or less than the second speed. By utilizing a dynamic speed adjustment mechanism, the shaver is given more flexible and efficient shaving performance. When the transmission component 3 drives the foil component 4 to accelerate shaving in the forward direction, that is, the rotational speed gradually increases from the first speed to the second speed, this acceleration mechanism greatly improves the dynamic adaptability of shaving. The lower speed in the initial stage allows the foil component 4 to gently conform to the skin, reducing discomfort at the beginning of shaving, and is especially suitable for starting shaving on sensitive areas such as the chin and neck. As the speed gradually increases, the cutting force of the foil component 4 and the inner blade component 5 continuously increases, enabling rapid and powerful processing of dense beard areas, achieving a smooth transition from gentle start to efficient shaving. This gradual acceleration shaving mode avoids potential skin irritation from starting at high speed, maximizes shaving efficiency in areas with dense beards, significantly shortens shaving time, and reduces skin damage from repeated shaving of the same area. The forward deceleration shaving mode, where the foil assembly 4 gradually decreases in rotation speed from a high initial speed to a lower second speed, offers unique advantages during shaving. At high speed, the powerful cutting force quickly handles large areas of beard, efficiently reducing beard length and improving shaving efficiency. As the speed gradually decreases, the foil assembly 4 and inner blade assembly 5 work together more precisely, accurately capturing residual beard hairs and meticulously addressing hard-to-shave areas such as around the lips and Adam's apple. The low-speed operation effectively reduces friction between the foil assembly 4 and the skin, lowering the risk of burning and redness caused by high-speed vibration, making it particularly suitable for users with sensitive skin or fine beards. In addition, in deceleration shaving mode, the load on the transmission component 3 and the blade assembly 4 is gradually reduced, which effectively extends the service life of each component, reduces mechanical wear caused by long-term high-speed operation, reduces product maintenance costs, and ensures long-term stable working performance while providing a comfortable shaving experience.

[0048] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that when the transmission component 3 drives the foil component 4 to rotate in the second direction according to the second mode, the rotational speed of the foil component 4 changes from the third speed to the fourth speed, where the third speed is greater than or less than the fourth speed. By utilizing a dynamic speed adjustment mechanism, the shaver is given more flexible and efficient shaving performance. When the transmission component 3 drives the foil component 4 to accelerate shaving in the reverse direction in the second mode, that is, the rotational speed gradually increases from the third speed to the fourth speed, this reverse acceleration mechanism can effectively compensate for the cutting blind spots during forward shaving. Since beards grow in different directions, some beard hairs may be difficult to cut completely during forward shaving due to angle issues. However, during reverse acceleration shaving, the cutting angle between the foil component 4 and the inner blade component 5 changes, and as the speed gradually increases, a new pulling and cutting force can be formed on the remaining beard hairs. At low speeds, the foil assembly 4 gently contacts the skin, allowing room for adjusting the shaving angle, making it suitable for hard-to-reach areas such as the back of the neck and sideburns. As the rotation speed increases, the powerful cutting force precisely cuts stubborn hairs, achieving a thorough shave. Simultaneously, during reverse acceleration, the contact pressure between the foil assembly 4 and the skin gradually increases, better conforming to facial contours and further improving shaving efficiency and cleanliness. The reverse deceleration shaving technique, where the foil assembly 4's rotation speed gradually decreases from a higher third speed to a fourth speed, also offers significant advantages. At high speeds, the rapidly rotating foil assembly 4 can quickly process a large area of ​​beard, rapidly reducing beard density. Towards the end of the shave, the rotation speed gradually decreases, allowing the foil assembly 4 to perform a more delicate second trim, ensuring no hairs are missed. For areas with skin folds or uneven surfaces, the low-speed foil provides a better fit, avoiding shaving and pulling caused by high-speed rotation, greatly improving shaving comfort and safety.

[0049] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the blade foil assembly 4 rotates at an angle of 2 degrees or more in the first mode. By setting the rotation angle of the first mode to 2 degrees or more, the larger rotation angle allows the blade foil assembly to better conform to the facial contours. During shaving, for uneven areas of the face, such as the nasolabial folds and jaw angle, the blade foil assembly can adjust its angle by rotating at least 2 degrees to more comprehensively cover the beard growth area, reduce shaving dead spots, thereby improving the cleanliness of the shave and avoiding the occurrence of beard residue.

[0050] like Figure 1As shown, in addition to the features of the above embodiments, this embodiment further specifies that the blade foil assembly 4 rotates at an angle of 2 degrees or more in the second mode. By setting the rotation angle of the second mode to 2 degrees or more, the larger rotation angle allows the blade foil assembly to better conform to the facial contours. During shaving, for uneven areas of the face, such as the nasolabial folds and jaw angle, the blade foil assembly can adjust its angle by rotating at least 2 degrees to more comprehensively cover the beard growth area, reduce shaving dead spots, thereby improving the cleanliness of the shave and avoiding the occurrence of beard residue.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a main housing 11, a support housing 12, and a charging housing 13. The support housing 12 is disposed at one end of the main housing 11, and the charging housing 13 is disposed at the other end of the main housing 11. The main housing 11, the support housing 12, and the charging housing 13 enclose and form a receiving cavity 101. By utilizing the main housing 11, the support housing 12, and the charging housing 13 to form the receiving cavity 101, the shaver gains many significant benefits. The main housing 11, as the core area, centrally houses key components such as the drive assembly 2 and transmission assembly 3, providing them with a stable operating space and ensuring efficient collaboration of the internal precision mechanical structure. The support housing 12, located at one end of the main housing 11, provides stable support for the front-end shaving components such as the foil assembly 4 and inner blade assembly 5, ensuring the stability of the shaving head during shaving and preventing wobbling that could affect the shaving effect. The charging housing 13, located at the other end of the main housing 11, integrates the charging interface, battery, and other charging-related components, enabling independent charging functionality and preventing interference with other components during charging. It also facilitates quick identification and use of the charging interface by the user. The main housing 11, support housing 12, and charging housing 13 work together to enhance the overall impact resistance of the shaver, effectively protecting internal components from damage during daily use or accidental drops, and extending the product's lifespan. Furthermore, this enclosed design makes the internal cable layout more organized, reducing the risk of short circuits and other malfunctions caused by messy cables.

[0052] like Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the main housing 11 includes a grip outer shell 111, a mounting inner shell 112, and a battery shell 113. The mounting inner shell 112 and battery shell 113 are both disposed on the grip outer shell 111 and located within the receiving cavity 101. The drive assembly 2, transmission assembly 3, and inner blade assembly 5 are all disposed on the mounting inner shell 112. By combining the grip outer shell 111, mounting inner shell 112, and battery shell 113 to form the main housing 11, significant benefits are brought to the shaver. The grip outer shell 111 can withstand daily bumps and knocks, protecting the internal structure. The mounting inner shell 112 serves as the base for the internal structure; its standardized mounting structure accurately positions the drive assembly 2, transmission assembly 3, and inner blade assembly 5, reducing installation errors and ensuring efficient operation of the components. Simultaneously, the reasonable mechanical design effectively disperses operating vibrations, reducing noise and shaking, and improving the shaving experience. The battery casing 113 independently houses the battery, isolating it from other components to prevent heat and electromagnetic interference from affecting performance during charging and discharging. The fire-resistant and insulating material further ensures battery safety, preventing risks such as short circuits and leakage. All three components fit tightly together within the housing 101, creating a compact and orderly spatial layout. This not only improves the shaver's durability and shaving stability, but the modular design also facilitates future replacement and maintenance of components such as the battery, reducing operating costs and achieving an efficient, safe, and convenient shaving experience.

[0053] like Figure 1 , Figure 5 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the support housing 12 includes an upper support housing 121, a lower support housing 122, and a foil support housing 123. The lower support housing 122 is disposed on the main housing 11, the upper support housing 121 is disposed on the lower support housing 122, the foil support housing 123 is disposed on the upper support housing 121, and the foil assembly 4 is disposed on the foil support housing 123. The lower support housing 122 is provided with multiple slots 102, which surround the lower support housing 122. By disposing of the lower support housing 122 on the main housing 11, stable support is provided for the upper structure. The upper support housing 121 is mounted on the lower support housing 122, further enhancing the overall stability of the support housing and providing a reliable load-bearing foundation for the foil support housing 123. The foil support housing 123 can accurately position the foil assembly 4, ensuring that the foil assembly 4 remains stable during operation and avoiding shaking or displacement, thereby ensuring the accuracy and efficiency of the shaving action. When the shaver experiences localized malfunctions or wear, the multiple slots 102 of the lower support shell 122 allow repair personnel or users to quickly separate the upper support shell 121 from the lower support shell 122, precisely locating internal components such as the foil support shell 123 and the foil assembly 4 for inspection or replacement, significantly reducing repair time and difficulty. Compared to traditional integrated structures, this eliminates the need for complete disassembly, reducing the risk of damage to other components due to excessive disassembly, improving repair efficiency, and lowering maintenance costs. For users seeking personalized cleaning, the upper support shell 121 can be easily removed for deep cleaning of internal components, preventing the accumulation of beard residue, dandruff, etc., from affecting shaving performance and hygiene, maintaining the shaver's high efficiency and cleanliness.

[0054] like Figure 4 , Figure 6 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further includes a battery assembly 6. The battery assembly 6 includes a charging device 61 and a battery body 62. The charging device 61 is disposed on the main housing 11, and the charging housing 13 is provided with a charging port 103. The charging device 61 and the charging port 103 are arranged opposite to each other. The battery body 62 is disposed on the main housing 11, and the battery body 62 and the charging device 61 are electrically connected via a PCB circuit board. By arranging the charging device 61 opposite to the charging port 103, the charging interface position is ensured to be accurate and easy to plug and unplug. Users can quickly connect the charging cable without complicated operations, achieving convenient charging. At the same time, this design reduces the problem of poor contact caused by interface misalignment during charging, effectively improving charging efficiency and shortening charging time. The charging device 61 is independently disposed on the battery housing 113, physically isolated from other components, which can prevent the heat and electromagnetic interference generated during charging from affecting other precision components inside the shaver, reducing the risk of failure caused by electromagnetic compatibility issues. The battery body 62 is also placed in the battery housing 113, providing it with safety protection to prevent short circuits, leakage, and other situations from affecting other components, ensuring user safety. The battery body 62 is electrically connected to the charging device 61, enabling efficient and stable power transmission and storage.

[0055] like Figure 1 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further includes a control component 7. The control component 7 includes a control button 71 and a circuit board 72. The circuit board 72 is disposed on the housing assembly 1, and the control button 71 is disposed on the circuit board 72 and passes through the housing assembly 1. By allowing direct interaction with the user through the housing assembly 1, the position and tactile feel of the control button 71 are carefully designed to conform to ergonomics, allowing the user to easily operate it with one hand during shaving to achieve functions such as power on / off, mode switching, and speed adjustment. The circuit board 72 integrates various control chips and circuit modules, precisely controlling the coordinated work of the drive assembly 2, transmission assembly 3, and battery assembly 6.
