Description

Technical Field

[0001] The present invention relates to the technical field of personal care devices, and particularly to a razor. Background Art

[0002] In the technical field of electric shaving devices, skin lubrication and residual liquid treatment during shaving have been the core pain points that have long troubled users. Traditional razors mostly rely on manually applying shaving cream or pre-coated lubricating strips. Such methods have significant drawbacks: it is difficult to precisely control the amount of lubricating liquid when applying manually. Excessive use will cause the liquid to seep into the blade gap and cause mechanical jamming. Moreover, the lubricating strip can only take effect briefly during the initial few shaves and cannot continuously protect the skin. More seriously, the residual lubricating liquid after shaving mixes with skin debris and adheres to the skin surface, forming a sticky layer. This not only requires users to wipe and clean frequently, but also easily breeds bacteria, and long-term use may induce folliculitis or skin allergic reactions.

[0003] For high-end models with reciprocating cutter heads, their high-frequency linear motion (60 - 120 Hz) further magnifies the difficulty of controlling the amount of lubricating liquid. The traditional unidirectional lubrication system cannot provide effective lubrication during reverse shaving, forcing users to repeatedly adjust the shaving direction, seriously affecting the operation continuity. Even if some models attempt to integrate a two-way liquid outlet function, its symmetric release design will cause the lubricating liquid to seep out simultaneously on both sides of the cutter net, not only wasting the liquid, but also forming liquid accumulation on the skin surface due to the counter-flow, further exacerbating the residue problem.

[0004] More critically, there is a lack of a residual liquid recovery mechanism that collaborates with the lubrication system in the existing technology. After the residual liquid repeatedly rubs between the cutter net and the skin, it will carry exfoliated cutin and bacteria and re-enter the shaving area, forming a vicious cycle of "pollution - residue - re-pollution". These problems severely restrict the upgrade of the user experience of electric shaving devices, and there is an urgent need for an integrated solution that can achieve precise lubrication and efficient residual liquid recovery synchronously during shaving. Summary of the Invention

[0005] (1) The technical problem to be solved by the present invention is that existing razors rely on manually applying lubricating liquid and cannot synchronously recover the residual liquid after shaving, resulting in a cumbersome lubrication process, a high risk of skin irritation, bacteria breeding caused by the residual liquid, and poor user experience.

[0006] (2) Technical Solution To solve the above technical problem, an embodiment of the present invention provides a razor, including a shaving area, a lubricating component, and a residual liquid collection component. The shaving area is provided with an isolation mesh cover at the top, and a cutter head component is arranged inside the isolation mesh cover. The cutter head component is used for shaving the hair and skin debris that enter the shaving chamber through the isolation mesh cover. The lubricating assembly includes a liquid storage part and a liquid outlet part. The liquid outlet part is arranged on the first side of the isolation mesh cover along the moving direction of the razor, and is configured to attach the lubricating liquid in the liquid storage part to the skin surface to form a pre-lubricating layer when the razor moves. The residual liquid collection assembly includes a liquid collection part and a waste liquid bin. The liquid collection part is arranged on the second side of the isolation mesh cover along the moving direction of the razor, and is opposite to the first side. The liquid collection part is used to collect the residual lubricating liquid on the skin surface after shaving, and convey the residual lubricating liquid to the waste liquid bin.

[0007] Wherein, the liquid outlet part and the liquid collection part are distributed on the moving path of the shaving area, so that when the razor works, the lubricating liquid is released, the hair is shaved, and the residual liquid is recovered in sequence.

[0008] According to an embodiment of the present invention, the liquid outlet part and the liquid collection part are both arranged on the first side and the second side of the isolation mesh cover. The first side and the second side are symmetrically arranged along the extending direction of the shaving area; a control device is further included, and the control device is configured to activate the liquid outlet part on the side corresponding to the moving direction and the liquid collection part on the other side in response to the moving direction of the razor.

[0009] By symmetrically arranging the bilateral liquid outlet parts and the liquid collection parts along the extending direction of the shaving area, and combining with the moving direction sensing control device, when the razor moves in both directions, the liquid outlet part on the side corresponding to the current moving direction automatically releases the lubricating liquid to form a pre-lubricating layer, and at the same time, the liquid collection part on the opposite side is synchronously started to recover the residual liquid. This design breaks through the limitations of the traditional unidirectional lubrication system, realizes the real-time dynamic adaptation of lubrication and recovery in the two-way shaving scenario, and the user can obtain a uniform lubrication and a dry experience throughout the process without adjusting the shaving direction, improving the operation efficiency and the hygienic safety.

[0010] According to an embodiment of the present invention, the liquid collection part includes a liquid collection tank and a closable cover plate. The closable cover plate is movably arranged at the opening of the liquid collection tank for selectively closing or opening the liquid collection tank; the liquid collection tank and the liquid outlet part are sequentially arranged on both sides of the isolation mesh cover along the moving direction of the razor, so that the liquid collection tank on each side is located between the liquid outlet part on the same side and the shaving area, and is communicated with the waste liquid bin through a diversion pipeline; the control device is configured to respectively control the opening and closing of the two closable cover plates.

[0011] By arranging the liquid collecting tank and the closable cover between the liquid outlet and the shaving area along the moving direction of the shaver, when the shaver moves, the liquid outlet releases new lubricating liquid, and the cover of the opposite liquid collecting tank opens based on the control command, so that the residual liquid is preferentially introduced into the waste liquid bin through the diversion pipeline. When the cover is closed, the opening of the liquid collecting tank is sealed to block the liquid reflux path on the same side. This design ensures the early recovery of residual liquid through spatial layout and opening and closing timing control, reduces the retention time of liquid on the skin surface, prevents the mixing and contamination of new and old liquids, and improves the system's closure and hygiene safety level.

[0012] According to one embodiment of the present invention, the closable cover is a foldable scraper, which is folded at a preset angle toward the skin surface when opened, and tilted to the moving path of the isolation mesh cover, so as to scrape the lubricating liquid remaining on the skin surface into the liquid collection tank when the shaver moves.

[0013] By designing the closable cover plate as a scraper structure that can be folded to a preset angle toward the skin surface, and tilted to the moving path of the isolation mesh cover when opened, the scraper plate contacts the skin surface during the movement of the shaver, and the residual lubricant is directed into the liquid collection tank by mechanical scraping. This design replaces the traditional passive adsorption scheme with a physical contact recovery mechanism of the folding action, effectively reducing the retention time of residual liquid on the skin surface; at the same time, when the scraper plate is closed, it forms a sealed interface with the opening of the liquid collection tank to prevent liquid back-seepage or external contamination, ensuring the closure of the recovery path and operational reliability.

[0014] According to one embodiment of the present invention, the inner side wall of the foldable scraper is provided with a guide groove extending along the folding direction of the scraper. By providing the guide groove extending along the folding direction on the inner side wall of the foldable scraper, when the scraper is opened and contacts the skin surface, the residual lubricating liquid flows along the guide groove to the liquid collection tank under the scraping action, accelerating the residual liquid to separate from the skin and be collected in a centralized manner, avoiding the attenuation of the recovery efficiency of the traditional flat scraper due to liquid diffusion; at the same time, the extension direction of the guide groove is consistent with the folding action of the scraper, ensuring that the liquid flow path matches the mechanical motion trajectory, further reducing the risk of liquid splashing back or retention, and improving the thoroughness and stability of residual liquid recovery.

[0015] According to one embodiment of the present invention, a flexible contact portion is provided at the end of the foldable scraper that contacts the skin. The flexible contact portion is configured to fit the contour of the skin surface in the folded state to scrape off residual liquid, and to form an elastic seal with the opening of the liquid collection tank when the scraper is closed.

[0016] By adding a flexible contact part at the end of the foldable scraper that contacts the skin, when the scraper is opened, the flexible contact part adaptively fits the undulating contour of the skin surface with the folding movement, enhancing the effect of scraping residual liquid and reducing the contact pressure through flexible deformation; when the scraper is closed, the flexible contact part is deformed under pressure to form an elastic sealing interface with the opening of the liquid collecting tank, blocking the backflow of liquid or the intrusion of external pollutants. This design adapts the dual functions of a single flexible structure, not only improving the efficiency of residual liquid recovery and skin comfort, but also ensuring the system tightness.

[0017] According to an embodiment of the present invention, the liquid storage part includes a detachable liquid storage box, a first fluid driving unit, and a first branch pipeline. The first fluid driving unit is configured to pump the lubricating liquid in the liquid storage box to the first branch pipeline, and the liquid storage box is communicated with the liquid outlet parts on the first side and the second side of the isolation mesh cover through the first branch pipeline respectively; The waste liquid bin includes a detachable waste liquid box, a second fluid driving unit, and a second branch pipeline. The second fluid driving unit is configured to suck the residual liquid in the second branch pipeline into the waste liquid box through negative pressure, and the waste liquid box is communicated with the liquid collecting parts on the first side and the second side of the isolation mesh cover through the second branch pipeline respectively; Flow control units are provided in both the first branch pipeline and the second branch pipeline. The flow control units are electrically connected to the control device and are configured to selectively conduct the liquid outlet parts and the liquid collecting parts on the first side or the second side in response to the moving direction of the razor.

[0018] Through the modular-designed liquid storage box and waste liquid box, combined with the two-way branch pipeline and the flow control unit, the directional control of lubricating liquid supply and residual liquid recovery is realized.

[0019] According to an embodiment of the present invention, the razor is a reciprocating razor, including a cutter head assembly. The isolation mesh cover is in the shape of an arc-shaped strip and is buckled outside the cutter head assembly, and its curvature adapts to the contour of the human face; The cutter head assembly includes a plurality of blades arranged at intervals along the arc extension direction of the isolation mesh cover, forming an array cutting unit, and the reciprocating movement direction of the blades is parallel to the arc axis of the isolation mesh cover.

[0020] By designing the isolation mesh cover as an arc-shaped strip structure and adapting to the curvature of the human face, and arranging the array cutting unit along the arc surface extension direction of the cutter head assembly, the reciprocating movement track of the blades naturally fits the facial contour, while saving space and increasing the working area for spraying lubricating liquid and recovering residual liquid.

[0021] According to an embodiment of the present invention, the razor further includes a cutter head cleaning mechanism, which includes an adsorbing member, a driving mechanism and a guiding mechanism. The driving end of the driving mechanism is connected to the adsorbing member and drives the adsorbing member to insert into the gaps of the array cutter head along the guiding mechanism to adsorb the residual liquid.

[0022] By integrating a cutter head cleaning mechanism in the razor, the driving mechanism drives the adsorbing member to periodically insert into the blade gaps through the guiding mechanism, and uses the surface adsorption force or negative pressure effect of the adsorbing member to remove the residual lubricating liquid and debris. The cutter head cleaning is performed during the shaving interval or after shaving. Without the user disassembling the cutter head assembly, the micron-level residues can be effectively removed, avoiding the problem of bacterial growth caused by the solidification of the liquid or the accumulation of debris, prolonging the service life of the cutter head and reducing the maintenance frequency.

[0023] According to an embodiment of the present invention, the liquid outlet part includes a liquid storage cavity and a rotating flow guiding member. The rotating flow guiding member is configured to carry out the lubricating liquid in the liquid storage cavity through rotational movement when the razor moves, and release it to the skin surface through surface contact; the rotational movement of the rotating flow guiding member can be switched to a stationary state.

[0024] Compared with the traditional spraying lubrication, the rolling lubrication releases the liquid by the contact between the rotating flow guiding member and the skin surface. By using the continuity of the rotational movement and the guiding effect of the surface texture, the lubricating liquid can be evenly covered without splashing waste, significantly reducing the consumption of the lubricating liquid; at the same time, the rotating flow guiding member can adaptively start and stop according to the moving direction of the razor, and switches to the stationary state when the device is stationary or moving in the reverse direction, avoiding the liquid seepage during non-working periods.

[0025] (III) Beneficial effects of the present invention: Through the collaborative layout of the lubrication component and the residual liquid collection component, the present invention dynamically releases the lubricating liquid and synchronously recovers the residual liquid during the movement of the razor, automatically forming a uniform pre-lubricating layer when the razor moves, avoiding uneven dosage caused by manual application, and at the same time eliminating the need to carry an additional lubricating liquid storage device, significantly reducing the shaving friction coefficient and reducing the risk of skin dryness and scratches; at the same time, the closed recycling path captures and isolates the residual liquid mixed with skin debris after shaving in real time through the mechanical diversion and directional recycling mechanism, blocking the bacterial growth environment. The entire system does not rely on user intervention or additional cleaning operations, and integrates lubrication release, hair cutting and residual liquid recovery in a single shaving action, realizing the coordination of efficient shaving and cleaning and maintenance.

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention. Specific Embodiment Embodiment

[0030] As Figures 1 to 7 shown, this embodiment provides an electric shaver with a reciprocating cutter head 121, including a body 5, a shaving area 1, a lubricating component 2 and a residual liquid collection component 3.

[0031] As Figures 1 to 4 shown, the body 5 serves as the main body of the shaver, with a power source (a lithium polymer battery component in this embodiment) provided inside, and a shaving area 1 is arranged in the middle area at the top. The shaver has a reciprocating structure, and the shaving area 1 includes a cutter head assembly and an isolation mesh cover 11 buckled on the outside thereof. The isolation mesh cover 11 is designed in an arc-shaped long strip semi-barrel shape, and its curvature is adapted to the contour of the area from the mandible to the cheekbone of the human face. Guide holes are evenly distributed on the surface of the mesh cover for guiding hair and skin debris into the shaving chamber. The cutter head assembly 12 arranges a plurality of ultra-thin blades (made of silicon nitride ceramics) at intervals along the arc extension direction of the isolation mesh cover 11 to form an array cutting unit. The blade spacing is optimized to balance the cutting efficiency and skin safety. The blades are driven by a linear drive motor in the body 5 and perform high-frequency reciprocating motion (frequency 100 - 150 Hz, stroke 1.5 - 2 mm) along the arc axis direction, ensuring that the cutting direction is always perpendicular to the beard growth angle and reducing the lateral friction on the skin at the same time. When the cutter head assembly 12 works, the hair enters the shaving chamber through the guide holes of the mesh cover and is cut by the reciprocating blades.

[0032] As Figures 2 to 5 shown, the lubricating component 2 includes a liquid storage part 21 and liquid outlet parts 22 symmetrically arranged on both sides. Among them, the liquid outlet parts 22 are arranged in parallel along the length direction of the isolation mesh cover 11, and maintain a constant distance from the surface of the mesh cover to adapt to the skin contact height, ensuring that the lubricating layer precisely covers the front edge of the shaving area 1. The liquid storage part 21 adopts a detachable liquid storage box 211 design. The box body is fixed to the body 5 through a magnetic interface, and stores a low-allergenic lubricating liquid (such as a water-soluble hyaluronic acid formula) inside. The liquid storage box 211 is connected to the liquid outlet part 22 on one side of the end of the isolation mesh cover 11 through a first branch pipeline 213. A micro peristaltic pump is embedded in the pipeline as the first fluid driving unit 212, and the flow rate of the lubricating liquid is controlled by pulsed pumping (the single pulse release amount is 0.02 - 0.05 ml) to avoid excessive leakage.

[0033] The bilateral liquid outlet part 22 is preferably a narrow-hole nozzle 221 structure. The inner cavity of the nozzle 221 communicates with the first branch pipeline 213, and micron-level diversion lines (such as wavy or spiral grooves) are provided at the outlet. When the razor moves, the control device 6 activates the corresponding side nozzle 221 according to the direction signal, and the lubricating liquid is evenly diffused to the skin surface through the diversion lines to form a continuous lubricating film; when moving in the reverse direction, the non-working side nozzle 221 is automatically closed to prevent liquid from flushing or dripping.

[0034] To further improve reliability, the branch pipeline is made of anti-bending aluminum alloy material, and self-locking quick-release joints are added at key connection nodes to facilitate users to replace the liquid storage box 211 or maintain the pipeline. The peristaltic pump integrates a flow feedback module. When it detects pipeline blockage or liquid exhaustion, it automatically triggers shutdown protection and prompts the user to repair, avoiding damage caused by idling.

[0035] As Figures 2 to 6 shown, the residual liquid collection assembly 3 includes a liquid collection part 31 and a waste liquid bin 32. The liquid collection part 31 is arranged on both sides of the isolation mesh cover 11 along the moving direction of the razor and is adjacent to the isolation mesh cover. Between the isolation mesh cover on the same side and the liquid outlet part 22, the liquid collection part 31 is used to collect the lubricating liquid remaining on the skin surface after shaving and convey the remaining lubricating liquid to the waste liquid bin 32.

[0036] The residual liquid collection assembly 3 includes a liquid collection part 31 and a waste liquid bin 32 symmetrically arranged on both sides of the isolation mesh cover 11. The liquid collection part 31 is composed of a liquid collection groove 311 and a closable cover plate 312. The liquid collection groove 311 is a strip-shaped groove extending along the length direction of the isolation mesh cover 11. A diversion protrusion 111 is provided on the inner wall of the groove adjacent to the isolation mesh cover. The width of the groove matches that of the liquid outlet part 22, and the position is adjacent to the shaving area 1 and behind the liquid outlet part 22, ensuring that the residual liquid preferentially enters the liquid collection groove 311 rather than flowing back to the knife net when the razor moves. The closable cover plate 312 is driven by a micro servo. Under normal conditions, it is closed to seal the groove opening. During operation, it folds forward by a preset angle (the maximum in this embodiment is 15°) towards the skin direction. After folding, the front end of the scraper is flush with the surface of the isolation mesh cover 11, and the rear end is tilted up to the shaving path, and the residual liquid on the skin surface is introduced into the liquid collection groove 311 through mechanical scraping.

[0037] As Figure 6As shown in the figure, the inner sidewall of the squeegee is provided with a V-shaped diversion groove 3121 extending along the folding direction. The inclination angle of the groove bottom is matched with the folding movement. By utilizing the surface tension of the liquid and the movement track of the squeegee, the residual liquid is guided to quickly flow into the liquid collection tank 311, avoiding the attenuation of the recovery efficiency caused by the liquid diffusion of the flat squeegee. The end of the squeegee in contact with the skin includes a flexible contact part 3122, which integrates a flexible contact layer of medical silicone. Its thickness and hardness are optimized. When folding, it adaptively fits the skin contour to enhance the scraping effect. When closed, it is deformed by extrusion to form an elastic seal with the notch, blocking the backflow of the liquid or the intrusion of external pollutants.

[0038] As Figures 2 to 5 shown, the waste liquid tank 32 is connected to the bilateral liquid collection tank 311 through the second branch pipeline 323, and is respectively arranged at both ends of the shaving area 1 in the body 5 of the razor, which is beneficial to saving space. The second branch pipeline 323 is embedded with a one-way valve to prevent the liquid from flowing back. The main body of the waste liquid tank 32 is a detachable filter box, and an activated carbon adsorption layer and multiple layers of filter screens are arranged inside, which are used to intercept debris and neutralize odors. The second fluid driving unit 322 uses a micro vacuum pump, and the negative pressure value is set to -10 to -20 kPa. When starting, the residual liquid in the liquid collection tank 311 is sucked into the waste liquid tank 32 through the branch pipeline. The measured single shaving residual liquid recovery rate exceeds 90%. The waste liquid box 321 is fixed to the body 5 through a buckle structure, and the user can regularly disassemble and clean it or replace the filter element, and the system sealing performance is not affected during maintenance.

[0039] The cutter head cleaning mechanism 4 is integrated inside the razor, and includes an adsorbing part 41, a driving mechanism 42 and a guiding mechanism. The adsorbing part 41 is a flexible microporous adsorption head, and the material is selected from medical silicone or ultra-fine fiber composite material. Micron-level pores are distributed on the surface to enhance the adsorption force. The driving mechanism 42 uses a micro linear motor, which is connected to the adsorbing part 41 through a rigid connecting rod, and drives it to reciprocate along the extending direction of the shaving area 1. The guiding mechanism is an arc-shaped slide rail, which is matched with the curvature of the isolation mesh cover 11 to ensure that the adsorbing part 41 is accurately inserted into the gap of the array cutter head.

[0040] The control device 6 is integrated in the razor body 5, and is composed of a direction sensor, a pressure sensor, a flow sensor, a main control unit and an actuator, which is used to coordinate the linkage operations of lubricant release, residual liquid recovery and cutter head cleaning in real time. The direction sensor uses a six-axis inertial measurement unit (including a gyroscope and an accelerometer), detects the moving direction and acceleration of the razor at a sampling rate of 200 Hz, and eliminates the interference of hand jitter through the Kalman filtering algorithm to accurately determine the shaving direction (A→B or B→A). The pressure sensor is embedded in the nozzle 221 of the liquid outlet part 22 and the contact surface of the squeegee in the liquid collection part 31, monitors the skin contact pressure (range 0-10 N), and the feedback data is used to dynamically adjust the lubricant flow rate. The flow sensor is built into the first branch pipeline 213 and the second branch pipeline 323 to monitor the lubricant release amount and the residual liquid flow rate in real time to ensure the stability of the system operation.

[0041] The main control unit runs an adaptive control algorithm based on a low-power microprocessor and triggers the corresponding functions on the corresponding side according to the direction signal: When the shaver moves in the direction of A→B: Activate the micro peristaltic pump of the liquid outlet part 22 on side A, and release the lubricating liquid in a pulsed manner (single pulse volume 0.02 - 0.05 ml). The lubricating liquid evenly covers the skin surface through the diversion lines of the narrow-hole nozzle 221; Simultaneously turn on the micro servo of the liquid collection part 31 on side B, drive the scraper to fold by 15°, and the V-shaped diversion groove 3121 on the inner side of the scraper guides the residual liquid into the liquid collection tank 311. At the same time, start the vacuum pump on side B (negative pressure -15 kPa), and suck the residual liquid to the waste liquid box 321 through the second branch pipeline 323; Close the cover plate of the liquid collection tank 311 on side A to block the liquid reflux path.

[0042] When the shaver moves in the reverse direction (B→A): The control logic is executed in mirror image, activating the liquid outlet on side B and the recovery on side A to ensure the coherence of two-way shaving.

[0043] The flow control unit (two-way solenoid valve) is embedded in the branch pipeline node, and selectively conducts the pipeline in response to the direction signal: When moving forward, it conducts the liquid outlet pipeline on side A and the recovery pipeline on side B; when moving in the reverse direction, it switches to the liquid outlet on side B and the recovery on side A, strictly isolating the new and old liquid paths to avoid cross-contamination. If the flow sensor detects that the bilateral flow deviation exceeds 30%, or the pressure sensor feedbacks that the contact pressure exceeds 5 N, the control device 6 immediately closes the peristaltic pump and triggers the buzzer alarm (beeping 3 times at a high frequency). At the same time, the LED indicator light turns red and flashes, prompting the user to check the pipeline or adjust the operation force.

[0044] The control of the cutter head cleaning mechanism 4 is independent of the main process. The user can manually trigger it through the body button or the system can automatically start it after continuous use for 30 minutes: The micro linear motor drives the adsorbing part 41 to insert into the blade gap along the arc-shaped slide rail (speed 0.5 mm / s), and the adsorption head captures the residual debris through the surface micropores; After the cleaning is completed, the adsorbing part 41 retracts into the storage bin, and the vibration module shakes off the debris at a frequency of 50 Hz.

[0045] After shaving is completed or when the static time exceeds 5 seconds, the control device 6 turns off all execution modules, the scraper resets to seal the liquid collection tank 311, and the vacuum pump maintains low-power operation to keep the pipeline under negative pressure. The system enters the standby state (the LED blue light is always on). When the battery power is lower than 10%, non-core functions (such as the cleaning mechanism) are automatically disabled to give priority to ensuring the basic shaving operation. Embodiment

[0046] As Figure 7As shown, its overall structure is the same as that of the body 5, shaving area 1, cutter head assembly and residual liquid collection assembly 3 of the first embodiment. The core improvement lies in replacing the nozzle 221 of the liquid outlet part 22 with a combination of a liquid cavity 222 and a rotating flow guiding member 223, and realizing the uniform release of the lubricating liquid through mechanical rolling.

[0047] The liquid outlet part 22 includes a liquid storage cavity 222 and a rotating flow guiding member 223. The liquid storage cavity 222 is integrated in the bases on both sides of the isolation mesh cover 11 and is communicated with the liquid storage box 211 through a flexible conduit. A one-way valve is provided at the outlet of the cavity to prevent liquid backflow. The rotating flow guiding member 223 is a ceramic roller with flow guiding patterns engraved on its surface. Both ends of the roller are connected to the side wall of the cavity through bearings and are driven to rotate by a micro stepping motor. When the shaver moves, the roller contacts the skin and rolls, and the lubricating liquid in the liquid storage cavity 222 is evenly taken out and released onto the skin surface by using the surface patterns and capillary action; when it is stationary or moving in the reverse direction, the roller is disengaged from the motor through an electromagnetic clutch and rotates freely to stop supplying liquid, preventing liquid from leaking out in the non-working state.

[0048] The residual liquid collection assembly 3, the cutter head cleaning mechanism 4 and the control device 6 are completely compatible with those of the first embodiment. The control device 6 synchronously activates the rotation of the roller on the corresponding side and the residual liquid recovery function on the opposite side according to the shaving direction signal to ensure the timing matching of the lubricating liquid release and recovery. The folding angle of the scraper is designed to adapt to the viscosity characteristics of the rolling lubricating liquid. The flexible contact layer fits the skin contour during scraping and elastically seals the liquid collection groove 311 when closed. The waste liquid bin 32 sucks the residual liquid through a branch pipeline, and the waste liquid box 321 is detachable and replaceable, and the maintenance process is the same.

[0049] This embodiment replaces the traditional spraying with rolling lubrication, improves the uniformity and controllability of liquid distribution, and at the same time avoids liquid splashing or cutter net pollution, and is especially suitable for sensitive skin and high-precision shaving scenarios. The start-stop control and direction sensing logic of the rotating flow guiding member 223 are seamlessly integrated to ensure the reliability and user-unnoticed experience of the system in two-way operation.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
