Description

Technical Field

[0001] This application relates to the field of razor technology, and in particular to a razor head assembly and a razor. Background Technology

[0002] A razor is an electrical appliance used to shave beards and sideburns and groom oneself. It is widely used because it is easy to operate and portable.

[0003] Currently, electric shavers on the market, especially rotary electric shavers, experience significant resistance during the contact and movement of the shaver head with the skin, resulting in uneven movement and reduced shaving speed. This negatively impacts shaving comfort and efficiency. Utility Model Content

[0004] In view of this, this application provides a razor head assembly and a razor that can improve the movement speed of the razor head assembly, thereby improving shaving efficiency and shaving comfort.

[0005] Specifically, the following technical solutions are included:

[0006] In a first aspect, this application provides a cutter head holder assembly, the cutter head holder assembly comprising:

[0007] A housing having a receiving cavity;

[0008] A vibrating element is disposed within the receiving cavity;

[0009] A fixing member, which cooperates with the vibrating member, is used to limit the position of the vibrating member and enable the vibrating member to transmit vibration to the housing.

[0010] In the technical solution of this application, a fixing member is used to position the vibrating member in the receiving cavity. During the shaving process, the vibrating member generates vibration and transmits the vibration to the housing, causing the head assembly to drive the head assembly of the shaver to vibrate. This reduces the friction between the head assembly and the user's skin during shaving, increases the moving speed of the head assembly, and provides the user with a more comfortable and smooth shaving experience. It also reduces skin deformation and wrinkles, captures and cuts hair more efficiently, and improves shaving efficiency.

[0011] In one possible implementation, the fastener has a mating surface for contacting the vibrating element, the shape of which is adapted to the shape of the vibrating element.

[0012] In the technical solution of this application, the mating surface constitutes a contour design of the vibrating component, which increases the contact area between the fixing component and the vibrating component, enhances the limiting effect of the fixing component on the vibrating component, further improves the installation stability and reliability of the vibrating component, and avoids the vibrating component from shifting or moving within the cavity; at the same time, the vibrating component can better transmit vibration to the fixing component, and transmit the vibration to the housing through the fixing component, thereby improving the vibration transmission efficiency.

[0013] In one possible implementation, the vibrating element is a vibration motor.

[0014] In the technical solution of this application, the technology and structure of the vibration motor are mature, the performance is stable and reliable, and the working efficiency is high. Setting the vibration component as a vibration motor is beneficial to reducing production costs and ensuring vibration effect.

[0015] In one possible implementation, the vibrating element includes a connected motor body and an eccentric wheel, the eccentric wheel being eccentrically positioned on the output shaft of the motor body.

[0016] In the technical solution of this application, the vibrating component is an eccentric rotor vibration motor. The output shaft of the motor body can rotate around its own axis, thereby driving the eccentric wheel to rotate. During the rotation of the eccentric wheel, centrifugal force is generated due to the rotation shaft deviating from the geometric center, which in turn causes vibration.

[0017] In one possible implementation, the housing includes a cover plate and a base frame that are mated together, and the fastener is connected to the base frame to confine the vibrating element within the base frame.

[0018] In the technical solution of this application, the shell is a split design, which facilitates installation and maintenance and improves assembly convenience. The base frame supports the vibrating components, which helps to optimize the vibration transmission path and reduce intermediate energy loss.

[0019] In one possible implementation, the fastener is detachably connected to the base frame.

[0020] In the technical solution of this application, the fixing part and the base frame are detachably connected, which facilitates the replacement or repair of the vibrating part, helps to reduce maintenance costs, and improves the service life of the shaver head assembly and the shaver.

[0021] In one possible implementation, the base frame and the fastener are connected by threaded fasteners.

[0022] In the technical solution of this application, the threaded fastener provides reliable connection strength and repeatable disassembly and assembly effect for the base frame and the fixing parts, which can prevent the base frame and the fixing parts from loosening due to the vibration of the vibrating parts.

[0023] In one possible implementation, the cutter head assembly further includes a decorative element, and the base frame has an opening on the side opposite to the cover plate, with the decorative element circumferentially disposed at the opening, and the decorative element being a flexible element.

[0024] In the technical solution of this application, the decorative part, which is a flexible component, is placed around the opening. It can play a role in buffering and shock absorption between the housing and the handle assembly, reducing the direct impact of housing vibration on the handle assembly, which is beneficial to reducing noise and improving grip comfort. At the same time, the decorative part can cover the internal structure of the housing and enhance the aesthetics of the head assembly and the shaver.

[0025] In one possible implementation, the cutter head assembly further includes a first pressure plate that is pressed around the end of the decorative element for connection with the base frame, and at least a portion of the vibrating element is supported by the first pressure plate.

[0026] In the technical solution of this application, the first pressure plate simultaneously fixes the decorative part and supports the vibration part, playing multiple roles. This helps to reduce the number of independent parts of the cutter head assembly, improve the internal space utilization of the cutter head assembly, and make the structure of the cutter head assembly more concise and compact.

[0027] In one possible implementation, the base frame is provided with a limiting part, which is located at the opening and protrudes from the inner wall of the base frame, and the limiting part is used to limit at least one end of the vibrating member.

[0028] In the technical solution of this application, by setting a limiting part, the end of the vibrating component is constrained and limited by the limiting part, so as to avoid axial movement of the vibrating component, which is beneficial to improving the installation stability and reliability of the vibrating component.

[0029] In one possible implementation, the blade holder assembly further includes a second pressure plate, which is pressed against the end of the first pressure plate away from the decorative element. The end of the limiting portion is provided with an inward flange, which is used to limit the second pressure plate.

[0030] In the technical solution of this application, the limiting part plays a multiple constraint and limiting role. It can not only limit the vibration member in the axial direction, but also limit the second pressure plate in the axial direction of the second pressure plate by using the inner flange. This helps to reduce the number of independent parts of the cutter head assembly, improve the internal space utilization of the cutter head assembly, and make the structure of the cutter head assembly more concise and compact.

[0031] Secondly, this application provides a razor, the razor including a head assembly provided in any embodiment of the first aspect, and further including a handle assembly and a head assembly, the two ends of the head assembly being connected to the handle assembly and the head assembly respectively.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions. When the product is placed in different orientations, the orientation may change; for example, "up" and "down" may be interchanged.

[0049] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0050] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0051] A razor is an electrical appliance used to shave beards and sideburns and groom oneself. It is widely used because it is easy to operate and portable.

[0052] Currently, electric shavers on the market, especially rotary electric shavers, produce a "head wave" phenomenon during the contact and movement of the shaver head with the skin. The "head wave" phenomenon is analogous to the wave formed at the bow of a ship moving through water; a large bow wave slows the ship down. Applied to the shaver industry, the "head wave" phenomenon manifests as raised wrinkles on the skin at the front of the shaver head during shaving. These wrinkles increase the resistance the shaver head experiences, hindering its smooth movement and reducing its speed, thus affecting shaving comfort and efficiency.

[0053] like Figure 1 and Figure 2As shown, the cutter head assembly 1 provided in this application embodiment includes a housing 11, a vibrating element 12, and a fixing element 13.

[0054] Exemplarily, the head assembly 1 is applied to a rotary electric shaver, such as... Figure 6 As shown, the rotary electric shaver also includes a head assembly 2 and a handle assembly 3. The two ends of the head holder assembly 1 are connected to the head assembly 2 and the handle assembly 3, respectively. The handle assembly 3 contains a battery. When the vibrator 12 is an electrically powered component, the vibrator 12 can be electrically connected to the battery in the handle assembly 3, using the battery to power the vibrator 12. Alternatively, the battery can be housed within the receiving cavity 111 of the head holder assembly 1. The head assembly 2 includes a rotating blade for cutting hair, and the head holder assembly 1 supports the rotating blade.

[0055] like Figure 2 As shown, the housing 11 has a receiving cavity 111, the vibrating element 12 is disposed in the receiving cavity 111, and the fixing element 13 cooperates with the vibrating element 12. The fixing element 13 is used to limit the vibrating element 12 and enable the vibrating element 12 to transmit vibration to the housing 11.

[0056] Optionally, the vibrating component 12 is a structural component capable of generating vibration, such as a vibration motor, a buzzer, or a piezoelectric ceramic assembly.

[0057] Under the limiting effect of the fixing member 13, the position of the vibrating member 12 in the receiving cavity 111 remains relatively fixed. The fixing member 13 improves the installation stability and reliability of the vibrating member 12 and avoids the vibrating member 12 from shifting or moving within the receiving cavity 111.

[0058] The vibrating element 12 generates vibration when the shaver is working, which is then transmitted to the housing 11 and the head assembly 2. This causes the head assembly 2 to vibrate while cutting hair, suppressing the "head wave" phenomenon and reducing the undulations and wrinkles on the user's skin caused by the "head wave" phenomenon. This reduces the friction between the head assembly 2 and the user's skin, thereby increasing the movement speed of the head assembly 2 on the user's skin. This makes the movement of the head assembly 2 smoother and more fluid, improving the user's shaving feel and comfort, and also increasing shaving efficiency.

[0059] Optionally, the vibrating element 12 can directly contact the housing 11 and transmit vibration, or it can indirectly transmit vibration to the housing 11 through the fixing element 13 or other structural elements.

[0060] To better verify the effect of the shaver using the head assembly 1 provided in the embodiments of this application, the applicant conducted performance tests on shavers with no vibration mode in the related art and shavers using the head assembly 1 provided in the embodiments of this application. The dynamic friction coefficient between the head assembly and the contact surface and the average sliding speed of the head assembly on the contact surface were verified respectively. The test results were the average of ten tests.

[0061] like Figure 7 As shown in the figure, the dynamic friction coefficient test results of a vibration-free shaver and a shaver using the head holder assembly 1 provided in the embodiments of this application are illustrated below. Figure 7 The details of the experiment will be explained in detail.

[0062] The first group served as the control group for the second group. The first group tested the coefficient of kinetic friction between the shaver head assembly and the contact surface when the shaver head assembly was not working in the non-vibration mode. The second group tested the coefficient of kinetic friction between the shaver head assembly 2 and the contact surface when the shaver head assembly 1 provided in this application was not working and the vibrating element 12 was vibrating. The test results from the first and second groups show that, when the shaver head assembly was not working, the coefficient of kinetic friction between the shaver head assembly 2 and the contact surface of the shaver using the shaver head assembly 1 provided in this application is lower, approximately 39% lower than that of the shaver in the non-vibration mode. This indicates that the smoothness of movement of the shaver head assembly 2 using the shaver head assembly 1 provided in this application is improved by approximately 39%, effectively improving shaving feel and comfort.

[0063] The third group served as the control group for the fourth group. The third group tested the coefficient of kinetic friction between the shaver head assembly and the contact surface when the shaver head assembly was working in vibration-free mode. The fourth group tested the coefficient of kinetic friction between the shaver head assembly 2 and the contact surface when the shaver head assembly 1 provided in this embodiment was working and the vibrating element 12 was vibrating. The test results from the third and fourth groups show that, when the shaver head assembly was working, the coefficient of kinetic friction between the shaver head assembly 2 and the contact surface using the shaver head assembly 1 provided in this embodiment was lower, approximately 35% lower than that of the shaver in vibration-free mode. This indicates that the smoothness of movement of the shaver head assembly 2 using the shaver head assembly 1 provided in this embodiment is improved by approximately 35%, effectively improving shaving feel and comfort.

[0064] according to Figure 7 The test results show that the shaver using the head assembly 1 provided in this application has a lower coefficient of dynamic friction and higher smoothness than a conventional vibration-free shaver.

[0065] like Figure 8 As shown in the figure, the test results of the sliding speed of the shaver head assembly are illustrated in the related art, specifically in a vibration-free mode and in a shaver using the shaver head holder assembly 1 provided in the embodiments of this application. The following section discusses... Figure 8 The details of the experiment will be explained in detail.

[0066] The first group served as the control group for the second group. The first group tested the sliding speed of the shaver head assembly on the contact surface when the shaver head assembly was not working in the non-vibration mode. The second group tested the sliding speed of the shaver head assembly 2 on the contact surface when the shaver head assembly 2 was not working and the vibrator 12 was vibrating, using the shaver head holder assembly 1 provided in this application embodiment. The test results from the first and second groups show that, when the shaver head assembly was not working, the sliding speed of the shaver head assembly 2 using the shaver head holder assembly 1 provided in this application embodiment was higher, approximately 16% higher than that of the shaver in the non-vibration mode. This indicates that the shaver using the shaver head holder assembly 1 provided in this application embodiment has higher shaving efficiency.

[0067] The third group served as the control group for the fourth group. The third group tested the sliding speed of the shaver head assembly on the contact surface when the shaver head assembly was working in vibration-free mode. The fourth group tested the sliding speed of the shaver head assembly 2 on the contact surface when the shaver head assembly 2 was working and the vibrator 12 was vibrating, using the shaver head holder assembly 1 provided in this application embodiment. The test results from the third and fourth groups show that, when the shaver head assembly is working, the sliding speed of the shaver head assembly 2 on the contact surface using the shaver head holder assembly 1 provided in this application embodiment is higher, approximately 12% higher than that of the shaver in vibration-free mode. This indicates that the shaver using the shaver head holder assembly 1 provided in this application embodiment has higher shaving efficiency.

[0068] according to Figure 8 The test results show that the shaver using the head assembly 1 provided in this application has a higher head assembly sliding speed than the conventional vibration-free shaver, resulting in a better shaving effect in the same amount of time and effectively improving shaving efficiency.

[0069] like Figure 9 As shown in the figure, the shaving performance is illustrated by a line graph comparing a vibration-free shaver in the related art and a shaver using the head assembly 1 provided in this embodiment. Line a represents the shaving performance of the vibration-free shaver in the related art, and line b represents the shaving performance of the shaver using the head assembly 1 provided in this embodiment. It can be seen that with increasing shaving frequency, the shaver using the head assembly 1 provided in this embodiment significantly achieves a higher shaving performance and better shaving results than a conventional vibration-free shaver.

[0070] The head assembly 1 provided in this application embodiment uses a fixing member 13 to position the vibrating member 12 in the receiving cavity 111. During the shaving process, the vibrating member 12 generates vibration and transmits the vibration to the housing 11, causing the head assembly 1 to drive the shaver head assembly 2 to vibrate, thereby reducing the friction between the shaver head assembly 2 and the user's skin during shaving, increasing the moving speed of the shaver head assembly 2, and providing the user with a more comfortable and smooth shaving experience. It can also suppress the "head wave" phenomenon, reduce skin deformation and wrinkles, capture and cut hair more efficiently, and improve shaving efficiency.

[0071] In some embodiments, the fixing member 13 has a mating surface 131 for contacting the vibrating member 12, the shape of the mating surface 131 being adapted to the shape of the vibrating member 12.

[0072] like Figure 2 As shown, the mating surface 131 is used to mate with the top of the vibrating member 12, and the shape of the mating surface 131 is the same as the shape of the top of the vibrating member 12.

[0073] In this embodiment, the mating surface 131 forms a contoured design of the vibrating element 12, increasing the contact area between the fixing element 13 and the vibrating element 12, enhancing the limiting effect of the fixing element 13 on the vibrating element 12, further improving the installation stability and reliability of the vibrating element 12, and preventing the vibrating element 12 from shifting or moving within the receiving cavity 111; at the same time, the vibrating element 12 can better transmit vibration to the fixing element 13, and the vibration is transmitted to the housing 11 through the fixing element 13, thereby improving the vibration transmission efficiency.

[0074] In some embodiments, the vibrating element 12 is a vibration motor.

[0075] Optionally, the vibrating element 12 can be an eccentric rotor vibration motor, a linear resonant vibration motor, a piezoelectric ceramic motor, or the like.

[0076] Vibration motors have mature technology and structure, stable and reliable performance, and high working efficiency. Setting the vibrating component 12 as a vibration motor helps to reduce production costs and ensure vibration effect.

[0077] In some embodiments, such as Figure 5 As shown, the vibrating element 12 includes a connected motor body 121 and an eccentric wheel 122, with the eccentric wheel 122 eccentrically mounted on the output shaft of the motor body 121.

[0078] In this embodiment, the vibrating element 12 is an eccentric rotor vibration motor. The output shaft of the motor body 121 can rotate around its own axis, thereby driving the eccentric wheel 122 to rotate. During the rotation of the eccentric wheel 122, centrifugal force is generated due to the rotation axis deviating from the geometric center, which in turn causes vibration.

[0079] The eccentric rotor vibration motor has a simple and reliable structure, low cost, small size and high power density. By setting the vibrating element 12 as an eccentric rotor vibration motor, the manufacturing difficulty and production cost can be further reduced. It can also fit the compact space in the housing cavity 111, which is conducive to realizing the lightweight and miniaturized design of the shaver.

[0080] In some embodiments, the housing 11 includes a cover plate 112 and a base frame 113 that are connected to each other, and a fastener 13 is connected to the base frame 113 to confine the vibrating element 12 to the base frame 113.

[0081] like Figure 2 As shown, the cover plate 112 is connected to the top of the base frame 113. The base frame 113 has a hollow shell structure, and the vibrating element 12 and the fixing element 13 are both located inside the base frame 113. The cover plate 112 has a plate structure to more stably and reliably support the rotating cutter head of the cutter head assembly 2.

[0082] In this embodiment, the housing 11 is a split design, which facilitates installation and maintenance and improves assembly convenience. The base frame 113 carries the vibrating component 12, which helps to optimize the vibration transmission path and reduce intermediate energy loss.

[0083] In some embodiments, the fastener 13 is detachably connected to the base frame 113.

[0084] For example, the fastener 13 and the base frame 113 can be connected by detachable methods such as fastener connection, snap-fit ​​connection, column-hole connection, rotary lock connection, magnetic connection, etc.

[0085] By setting the fixing part 13 and the base frame 113 to be detachably connected, it is easy to replace or repair the vibrating part 12, which helps to reduce maintenance costs and increase the service life of the head assembly 1 and the shaver.

[0086] In some embodiments, the base frame 113 and the fastener 13 are connected by threaded fasteners 14.

[0087] For example Figure 3 and Figure 4 As shown, the base frame 113 has a threaded mating part 1132 protruding from it, and a threaded hole is provided in the threaded mating part 1132. The fastener 13 has a connecting hole 132. The threaded fastener 14 passes through the connecting hole 132 and is inserted into the threaded hole of the threaded mating part 1132. Tightening the threaded fastener 14 can realize the connection between the base frame 113 and the fastener 13.

[0088] The threaded fastener 14 can be a bolt, screw, or other threaded connector. The number of threaded fasteners 14, threaded mating parts 1132, and connecting holes 132 can be multiple, thereby improving the connection strength and reliability between the base frame 113 and the fastener 13. For example... Figure 3and Figure 4 As shown, there are two threaded fasteners 14, two threaded mating parts 1132, and two connecting holes 132.

[0089] In this embodiment, the threaded fastener 14 provides reliable connection strength and repeatable disassembly and assembly effect for the base frame 113 and the fixing member 13, which can prevent the base frame 113 and the fixing member 13 from loosening due to the vibration of the vibrating member 12.

[0090] In some embodiments, the blade holder assembly 1 further includes a decorative element 15, and the base frame 113 has an opening on the side opposite to the cover plate 112. The decorative element 15 is arranged around the opening and is a flexible element.

[0091] like Figure 1 and Figure 2 As shown, the decorative element 15 is in the shape of a ring and can be distributed around the opening of the base frame 113.

[0092] For example, the decorative part 15 is made of flexible materials such as soft rubber, silicone, etc., and has a relatively soft texture and a certain elastic deformation capability.

[0093] By placing the decorative element 15, which is a flexible component, around the opening, it can act as a buffer and shock absorber between the housing 11 and the handle assembly 3, reducing the direct impact of the vibration of the housing 11 on the handle assembly 3. This helps to reduce noise and improve grip comfort. At the same time, the decorative element 15 can cover the internal structure of the housing 11, enhancing the aesthetics of the head assembly 1 and the shaver.

[0094] In some embodiments, the blade holder assembly 1 further includes a first pressure plate 16, which is pressed around the end of the decorative member 15 for connection with the base frame 113, and at least a portion of the vibrating member 12 is supported by the first pressure plate 16.

[0095] like Figure 1 and Figure 2 As shown, the first pressure plate 16 is annular and is used to fix and limit the decorative part 15. The first pressure plate 16 presses the decorative part 15 tightly against the base frame 113, which improves the installation stability and reliability of the decorative part 15.

[0096] At least a portion of the bottom of the vibrating element 12 is supported by the first pressure plate 16. On the one hand, the first pressure plate 16 is used to transmit vibration and suppress the displacement of the vibrating element 12, so as to prevent the vibrating element 12 from shifting or moving in the height direction. On the other hand, the vibrating element 12 can also improve the connection tightness between the first pressure plate 16 and the decorative element 15, and further enhance the connection strength between the decorative element 15 and the base frame 113.

[0097] In this embodiment, the first pressure plate 16 simultaneously fixes the decorative part 15 and supports the vibration part 12, playing multiple roles. This helps to reduce the number of independent parts of the cutter head assembly 1, improve the internal space utilization of the cutter head assembly 1, and make the structure of the cutter head assembly 1 more concise and compact.

[0098] In some embodiments, the base frame 113 is provided with a limiting part 1131, which is located at the opening and protrudes from the inner wall of the base frame 113. The limiting part 1131 is used to limit at least one end of the vibrating member 12.

[0099] The limiting part 1131 can be one or more, for example Figures 2 to 4 As shown, the limiting part 1131 is located at the bottom of the base frame 113 and protrudes outward relative to the inner wall of the base frame 113. The three limiting parts 1131 are evenly spaced around the opening, and the vibrating member 12 is located between two of the limiting parts 1131.

[0100] Of course, when there is only one limiting part 1131, the limiting part 1131 can limit only one end of the vibrating member 12, or it can limit both ends of the vibrating member 12 at the same time by opening a receiving groove or the like.

[0101] In this embodiment, by setting a limiting part 1131, the end of the vibrating element 12 is constrained and limited by the limiting part 1131, so as to avoid the vibrating element 12 from axial movement, which is beneficial to improving the installation stability and reliability of the vibrating element 12.

[0102] In some embodiments, the blade holder assembly 1 further includes a second pressure plate 17, which is pressed against the end of the first pressure plate 16 away from the decorative member 15. The end of the limiting portion 1131 is provided with an inner flange 11311, which is used to limit the second pressure plate 17.

[0103] The second pressure plate 17 provides a certain supporting function for the components in the receiving cavity 111, for example... Figure 2 As shown, a portion of the bottom of the vibrating element 12 is supported by the second pressure plate 17. The second pressure plate 17 can also press the first pressure plate 16, improving the installation stability and reliability of the first cover plate 112 and the decorative element 15.

[0104] Please refer to Figure 2 The inner flange 11311 extends from the end of the limiting part 1131 along the radial direction of the base frame 113 toward the central axis, so that the limiting part 1131 is in an "L" shape. The limiting part 1131 can abut against the surface of the second pressure plate 17, thereby suppressing the axial movement of the second pressure plate 17, ensuring that the second pressure plate 17 does not leave the working position under vibration environment, and improving the stability of the second pressure plate 17.

[0105] In this embodiment, the limiting part 1131 has multiple constraint and limiting effects. It can not only limit the vibration member 12 in the axial direction, but also limit the second pressure plate 17 in the axial direction using the inner flange 11311. This helps to reduce the number of independent parts of the cutter head assembly 1, improve the space utilization inside the cutter head assembly 1, and make the structure of the cutter head assembly 1 more concise and compact.

[0106] Optionally, such as Figure 1 and Figure 2 As shown, the razor head assembly 1 also includes a floating seat 18 and an elastic member 19. The floating seat 18 is generally a hollow cylindrical structure. One end of the floating seat 18 is installed at the opening of the base frame 113 and is connected to the first pressure plate 16 and the decorative member 15, respectively. One end of the elastic member 19 engages with the second pressure plate 17, and the other end engages with the floating seat 18. During the vibration of the vibrating member 12, the elastic member 19 can provide a cushioning effect on the second pressure plate 17. Exemplarily, the floating seat 18 can be connected to the handle assembly 3 of the razor.

[0107] In some embodiments, such as Figure 6 As shown in the figure, this application embodiment also provides a razor, which includes the head assembly 1 provided in any of the above embodiments, and also includes a handle assembly 3 and a head assembly 2. The two ends of the head assembly 1 are respectively connected to the handle assembly 3 and the head assembly 2.

[0108] The blade assembly 2 includes a rotating blade for cutting hair, and the blade holder assembly 1 supports the rotating blade. The handle assembly 3 provides a gripping position for easier handling and use.

[0109] The shaver provided in this application embodiment has a head assembly 1 that drives the head assembly 2 to vibrate, thereby reducing the friction between the head assembly 2 and the user's skin during shaving, increasing the moving speed of the head assembly 2, providing the user with a more comfortable and smooth shaving experience, suppressing the "head wave" phenomenon, reducing skin deformation and wrinkles, capturing and cutting hair more efficiently, and improving shaving efficiency.
