Description

Technical Field

[0001] The present invention relates to the technical field of shaving devices, and particularly to an electric shaver. Background Art

[0002] In the technical field of electric shavers, the treatment of skin debris and hair residues generated during shaving has always been an important link affecting the user experience. When traditional shavers cut beards through the cutter head assembly, fine debris is likely to remain in the gaps of the cutter net or fly outside the shaving chamber. Due to the tiny size of beard debris and skin debris, traditional cleaning devices relying on air flow suction are extremely prone to dusting during the suction process, resulting in secondary diffusion of debris. This diffusion not only causes internal pollution of the shaver, but may also trigger skin allergies in users and even lead to hygiene problems such as bacterial growth.

[0003] To solve the above problems, two cleaning solutions are generally adopted in the prior art: one is to rinse the cutter head assembly with water after shaving, and the other is to configure a dedicated cleaning base for high-frequency vibration cleaning. However, both of these solutions have obvious defects. Among them, the water washing solution requires frequent disassembly of the cutter head assembly, which is cumbersome to operate and cannot achieve real-time cleaning; although vibration cleaning can partially remove debris, it cannot prevent the real-time scattering of debris during shaving operations.

[0004] In recent years, some improved solutions have tried to integrate a negative pressure chip suction system inside the shaver to guide debris into an independent collection bin through air flow. However, such designs have exposed new contradictions in practical applications: the interference between the high-speed air flow and the movement trajectory of the cutter head will form a turbulent area, which instead exacerbates the disordered diffusion of debris in the chamber. At the same time, noise will also be generated during this process. Tests show that the noise value of such systems during operation generally exceeds 55 dB(A), seriously affecting the use comfort.

[0005] Especially for shaving devices with reciprocating cutter heads, due to the working characteristics of high-frequency linear vibration (50 - 200 Hz) of their cutter head assemblies, traditional adsorption structures are difficult to effectively cooperate with the movement of the cutter head. Most existing adsorption devices adopt a fixed layout, which is prone to mechanical interference during the vibration of the cutter head, resulting in a decline in adsorption efficiency, and is prone to structural fatigue fracture after long-term operation. In addition, insufficient sealing of the collection device will cause the adsorbed debris to re-scatter when the device moves, forming repeated pollution.

[0006] Therefore, how to construct a real-time and efficient debris treatment system in a limited space, which can synchronously capture micron-sized debris during shaving and avoid problems such as secondary pollution and excessive noise caused by traditional solutions, has become a technical bottleneck that urgently needs to be broken through in the field of electric shavers. Summary of the Invention

[0007] (1) The technical problem to be solved by the present invention is that existing razors cannot capture and direct the collection of debris in real time during shaving, resulting in dust pollution and excessive noise, and it is difficult to adapt to high-frequency vibrating cutter heads.

[0008] (2) Technical solution To solve the above technical problems, an embodiment of the present invention provides an electric razor, including a razor main body. A shaving chamber, an electrostatic adsorption device and a collection device are provided inside the razor main body. A separation mesh cover is provided at the top of the shaving chamber, and a cutter head assembly is provided inside. The cutter head assembly is configured to shave hair and skin debris that penetrate into the shaving chamber from the separation mesh cover. The electrostatic adsorption device includes an electrostatic generator and an adsorbent. The adsorbent is arranged on the outer edge of the movement track of the cutter head assembly for adsorbing the substances to be adsorbed in the shaving chamber. The collection device includes a collection part and a storage part. The collection part is configured to receive the adsorbed substances falling off from the adsorbent when the electrostatic adsorption device stops working. The storage part is communicated with the collection part for centrally storing the adsorbed substances.

[0009] According to an embodiment of the present invention, the cutter head assembly includes two sets of cutting units, and an adsorption operation area is formed between the two sets of cutting units; the adsorbent is arranged in the adsorption operation area, and its effective adsorption range simultaneously covers the shaving operation areas of the two sets of cutting units.

[0010] By accurately arranging the adsorbent in the adsorption operation area formed by the two sets of cutting units, so that its effective adsorption range synchronously covers the shaving operation areas of the double cutter heads, synchronous capture of debris on both sides is realized in a single shaving action, effectively increasing the adsorption efficiency, saving space, and at the same time eliminating the problem of debris escape caused by asynchronous adsorption on both sides.

[0011] According to an embodiment of the present invention, the cutting unit includes a strip-shaped reciprocating cutter head, and the two sets of strip-shaped reciprocating cutter heads are arranged in parallel along their length directions; The adsorbent is a cylindrical adsorption net, which is arranged between the two sets of strip-shaped reciprocating cutter heads along the length direction of the reciprocating cutter head, and its axial length is not less than the length of any reciprocating cutter head, and the cylindrical adsorption net is equidistant from the two sets of reciprocating cutter heads.

[0012] By centrally arranging the cylindrical adsorption net along the length direction of the two sets of strip-shaped reciprocating cutter heads arranged in parallel and ensuring that its axial length completely covers the cutter head operation area, a surrounding electrostatic field is constructed. This cylindrical structure eliminates the edge effect of the traditional planar electrode and effectively increases the adsorption area. The cylindrical mesh structure forms a three-dimensional adsorption force field, enhancing the adsorption effect.

[0013] According to an embodiment of the present invention, the collection part includes a cylindrical cover body, which is configured to cover the adsorption part when the electrostatic adsorption device stops working. The cylindrical cover body includes a bottom collection plate and a circumferential side wall. The bottom collection plate is provided with a conduction port communicating with the storage part; a closable collection channel is provided on the circumferential side wall. The collection channel is opened during the adsorption operation to expose the adsorption part and closed during the collection operation to form a closed space.

[0014] Through the dynamic sealing design of the cylindrical cover body, a fully enclosed isolation space is formed when the electrostatic adsorption stops, completely blocking the diffusion path during the debris shedding process. The intelligent linkage of the collection channel with the adsorption operation state (opened to expose the adsorption surface during operation and closed to form a sealed cavity during collection) constructs a "dynamic sealing barrier", which not only ensures the efficient operation of the adsorption device during shaving, but also completely prevents secondary pollution through physical isolation during the collection stage. The directional cooperation between the bottom conduction port and the closed space forms a single channel for debris transfer, enabling the shed debris to reach the storage part along the preset path under the synergistic action of gravity and negative pressure without any risk of external exposure throughout the process.

[0015] According to an embodiment of the present invention, the cylindrical cover body further includes an arc-shaped sliding sealing plate integrally arranged on the circumferential side wall, and the sliding sealing plate conforms to the circumferential wall of the cylindrical cover body; The sliding sealing plate can slide along the arc-shaped guide of the circumferential wall. When the collection channel is closed, the sliding sealing plate covers the collection channel. When the collection channel is opened, the sliding sealing plate covers the conduction port.

[0016] Through the two-way sealing design of the arc-shaped sliding sealing plate, the conduction port and the collection channel are respectively blocked to form physical isolation in two operating states. When the cutter head assembly is running, the sliding sealing plate accurately displaces along the arc-shaped guide rail above the conduction port, cutting off the return path of the debris and effectively preventing the collected debris from escaping in the reverse direction; at the same time, the opened collection channel ensures the maximization of the exposed area of the adsorption part and maintains the electrostatic adsorption efficiency. When the cutter head assembly stops running, the collection channel is closed, and at the same time, the conduction port is opened for debris collection operation.

[0017] Through the two-way displacement of a single sliding part, the intelligent switching of "isolating the storage channel during adsorption and closing the operation area during collection" is realized, achieving the double sealing effect of anti-backflow and anti-diffusion with zero energy loss. In addition, this conformal sliding structure makes the movement trajectory of the sealing plate completely fit the inner wall of the cover body, eliminating the edge leakage problem existing in the traditional flip-type sealing plate.

[0018] According to an embodiment of the present invention, the cylindrical cover body further includes a top cover plate, which is an insulating plate. By adding an insulating plate to the top of the cylindrical cover body, a physical isolation barrier between the electrostatic field and the user's skin is constructed to reduce the discomfort that the electrostatic field may bring.

[0019] According to an embodiment of the present invention, the storage part includes a storage bin integrated on the side wall of the razor body. The collection part and the storage bin are connected through a conduction path, and the conduction path includes: A horizontal connection section, which is hermetically docked with the conduction port of the collection part to form a conduction groove; A vertical transition section, which extends from the end of the horizontal connection section along the inner wall of the razor body to the storage bin.

[0020] Through the coordinated setting of the horizontal connection section and the vertical transition section, a three-dimensional directional transfer channel from the collection part to the storage bin is constructed. The hermetic docking of the horizontal connection section and the conduction port forms a leak-proof diversion groove, enabling debris to slide into the vertical transition section along a preset path under the action of gravity; realizing the whole-process closed transfer of debris on the premise of occupying zero additional space. The combined design of this conduction path and the side-wall integrated storage bin compresses the space occupied by the collection module to the internal redundant area, keeping the thickness of the device the same as that of a traditional razor.

[0021] According to an embodiment of the present invention, an anti-sticking coating is provided on the inner walls of the collection part and the conduction path. By setting the anti-sticking coating on the inner walls of the collection part and the conduction path, the adhesion force between the debris and the channel surface is significantly reduced, ensuring that micron-level debris is transferred to the storage bin without residue under the action of gravity or negative pressure. A detachable sticky plate is provided in the storage bin, which captures and fixes the debris, not only preventing the debris from scattering and rebounding when the device moves, but also enabling the cleaning operation without contacting pollutants. The user only needs to replace the sticky plate to achieve "zero-contact" hygienic maintenance.

[0022] According to an embodiment of the present invention, the storage part is further provided with a negative pressure collection system, which is used to suck the adsorbents in the collection part and the conduction path into the storage bin.

[0023] Through the synergistic effect of the negative pressure collection system and the airtight collection part, a directional air flow is generated after the electrostatic adsorption stops, efficiently sucking the debris on the surface of the adsorbent and in the conduction path into the storage bin. The user only needs to trigger a negative pressure cycle once after shaving to complete the debris removal of the entire link, without additional maintenance operations and without noise during the shaving process.

[0024] According to an embodiment of the present invention, the collection device further includes a vibration mechanism, which is used to connect the adsorbent; the vibration mechanism is configured to drive the adsorbent to vibrate at a preset frequency and amplitude when the electrostatic adsorption device stops working.

[0025] Through the linkage of the vibration mechanism and the electrostatic adsorption device, high-frequency micro-amplitude vibration is triggered when the power is off, using mechanical shock waves to offset the residual adsorption force generated by the hysteresis effect of the electrostatic field and improving the cleaning effect of the adsorbent.

[0026] (III) Beneficial effects of the present invention: By integrating the electrostatic adsorption device on the outer edge of the movement trajectory of the cutter head assembly, the present invention can adsorb micron-sized debris generated in real time during shaving, avoiding the dust pollution caused by traditional air flow attraction. At the same time, the collection device and the electrostatic adsorption device work together to automatically receive and seal the shed debris after the static electricity stops, which not only solves the hygiene problems caused by debris residue in the prior art, but also avoids the movement interference with the high-frequency vibrating cutter head through the non-mechanical contact adsorption mechanism. The entire system does not require additional volume or generate high noise, realizing a non-intrusive operation during the shaving and cleaning process, significantly improving the service life of the device and the user's health and safety protection.

[0030] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. 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 efforts shall fall within the protection scope of the present invention. Specific embodiments

[0031] As Figures 1 to 8 shown, this embodiment provides a specific implementation manner of an electric shaver. Its core design lies in the coordinated work of electrostatic adsorption and a closed collection system to achieve efficient processing of shaving debris. The top of the electric shaver is the razor main body 4, with a buckled machine cover 41 on the top. The interior of the main body is divided into three parts: a shaving chamber 1, an electrostatic adsorption device 2, and a collection device 3. The top of the shaving chamber 1 is covered with an isolation mesh cover 11. The mesh cover is designed with openings using a metal material (such as a circular or oval stainless steel mesh plate), allowing beards to penetrate into the interior of the chamber. The blade assembly 12 arranged inside is driven by a power mechanism and can be adapted to a rotary or reciprocating blade 121. In this embodiment, two groups of reciprocating blades 121 arranged in parallel are selected (the blades are driven by a linear motor to vibrate at a high frequency to cut hair and skin debris), but in actual implementation, it can also be replaced with a three-blade rotary structure. At this time, the electrostatic adsorption device 2 can be correspondingly adjusted to an annular electrode array to adapt to the blade layout.

[0032] The electrostatic adsorption device 2 is integrated in the peripheral area of the blade movement track. In specific implementation, a cylindrical adsorption mesh, a plate-shaped electrode or a multi-segment electrode structure can be selected. Taking the cylindrical adsorption mesh as an example in this embodiment, it extends along the length direction of the blade, is arranged in the gap between two groups of reciprocating blades 121, is fixed to the inner wall of the chamber through an insulating bracket, and keeps an appropriate distance from the blade to avoid mechanical interference. The adsorption mesh is connected to the high-voltage electrostatic generator 21 in the razor handle, generating an electrostatic field during shaving to adsorb the scattered debris in real time.

[0033] The collection device 3 is composed of a collection part 31 and a storage part 32, and the two are connected through a guiding passage. The collection part 31 can adopt a cylindrical cover body, an inclined collection plate 311 or a movable hatch structure - in this embodiment, a cylindrical cover body is selected, and a collectable passage 312 that can be opened and closed is provided on its side wall. When the cutter head works, the collection passage 312 is opened to expose the adsorption net. When the work stops, the cover body moves upward to cover the adsorption net and closes the passage to form a closed space. For designs with limited space, the collection part 31 can be replaced with an inclined collection plate 311, and a vibration motor is used to assist the debris to slide into the guiding passage. A diversion port is provided at the bottom of the cover body, and its opening and closing are controlled by a slide rail or a rotating baffle. A guiding passage (such as a corrugated pipe, a spiral passage or a bifurcated pipeline) is connected below the diversion port to direct the debris to the storage bin 321 integrated on the side wall. The storage bin 321 is designed as a detachable filter box or an embedded container (a detachable filter box is selected in this embodiment), and the user can take it out regularly for cleaning. A sticky plate or a filter screen can be added inside to fix the debris. In this embodiment, it is a detachable sticky plate 3211.

[0034] The above design allows for flexible adaptation to different cutter head types and the internal space of the device. For example, a rotary cutter head can be paired with an annular electrode array, and a bifurcated guiding passage can optimize the debris transfer path in a narrow cavity. The replacement and combination of each component are all based on the core architecture of the present invention, that is, electrostatic adsorption is used to capture debris in real time, dynamic closed collection is used to prevent secondary pollution, and a directional passage is used to achieve efficient storage. These variant solutions are all within the protection scope of the claims of the present invention.

[0035] As Figure 3 and Figure 4 shown, in this embodiment, the cutter head assembly 12 is composed of two sets of cutting units arranged in parallel, and a continuous adsorption operation area is formed in the area between the two sets of cutting units. The cutting unit is a strip-shaped reciprocating cutter head 121, which is arranged in parallel along the length direction, and the length direction of the cutter head is consistent with the shaving movement direction. Each strip-shaped reciprocating cutter head 121 includes a blade group and a driving mechanism. The blade group is made of superhard ceramic material, and its surface is polished to reduce the friction resistance. It is connected to a linear motor through a rigid connecting rod to drive the blade to perform high-frequency reciprocating motion.

[0036] In the adsorption operation area between the two sets of strip-shaped reciprocating cutter heads 121, a cylindrical adsorption net is provided as the core component of the electrostatic adsorption device 2. The cylindrical adsorption net is woven from a metal conductive material, and the mesh size is adapted to the debris capture requirements. In this embodiment, it is a diamond-shaped hole, and the axial length covers the effective operation area of the cutter head and is fixed to the inner wall of the shaving chamber 1 through an insulating bracket. The adsorption net is equidistant from the cutter heads on both sides to ensure that the electrostatic field evenly covers the double-cutter head operation area. The insulating bracket is provided with a positioning structure for calibrating the relative position of the adsorption net and the cutter head, and the tolerance is controlled within a preset range to eliminate the risk of mechanical interference.

[0037] Both ends of the cylindrical adsorption net are connected to the high-voltage electrostatic generator 21 through elastic conductive contacts. The contact material is selected as a high-conductivity alloy to reduce the contact resistance. The high-voltage electrostatic generator 21 is fixed on the support 13 inside the razor main body 4, and the output voltage is adjustable to meet the requirements of different working conditions.

[0038] As Figures 5 to 8 shown, the electrostatic field in the adsorption working area can capture the debris generated by the cutter head cutting in real time, and the adsorption range completely covers the shaving working areas of the two groups of cutter heads. When the cutter head vibrates at a high frequency, the equidistant layout and mesh structure of the cylindrical adsorption net work together to form a stable three-dimensional adsorption force field, ensuring that the debris is immediately adsorbed and fixed after leaving the cutter head, and avoiding scattering or residue.

[0039] Furthermore, the collection part 31 is composed of a cylindrical cover body, and the inner wall is provided with an anti-sticking and electrostatic shielding layer (such as copper foil). The cover body is made of engineering plastic or metal material, and the overall structure is cylindrical, including a bottom collection plate 311, a circumferential side wall and a top cover plate 314 that work together. The bottom collection plate 311 is provided with a conduction port 3111, which is connected to the conduction path through a silica gel sealing ring to ensure the airtightness during debris transfer; the circumferential side wall is provided with an openable and closable collection channel 312, the width of the channel is adapted to the exposure requirement of the adsorbent 22, and a guiding slide rail is provided at the edge to control the opening and closing stroke.

[0040] The circumferential side wall is integrated with an arc-shaped sliding sealing plate 313. The sealing plate 313 is provided with two pieces that are conformally designed with the inner wall of the cover body and slide along the circumferential arc path through a sliding mechanism. In this embodiment, it is a circular rotating connecting plate arranged at the end, and the rotating connecting plate is driven by a rotating motor to connect the two sealing plates 313 respectively. When the razor is working, one of the two sliding sealing plates 313 moves above the conduction port 3111 to completely close the passage of the storage part 32, and at the same time, the collection channels 312 on both sides are completely opened to expose the adsorbent 22; when the work stops, the two sealing plates 313 slide to the position of the collection channel 312 to form a closed space, and at the same time, the conduction port 3111 is opened for debris transfer.

[0041] The top cover plate 314 is made of an insulating material (such as polycarbonate or ceramic composite material), which can be a part of the cover body or fixedly connected to the cylindrical cover body through a snap structure, and the thickness is adapted to the requirement of electric field attenuation. The inner surface of the cover plate maintains a preset gap with the top of the adsorbent 22 to reserve space for the rotation of the other sealing plate 313.

[0042] As Figures 1 to 4 shown, the storage part 32 is integrated on the side wall of the razor main body 4, and includes a storage bin 321 and a conduction path 34 connecting the collection part 31. The conduction path 34 is composed of a horizontal connection section 341 and a vertical transition section 342: the horizontal connection section 341 is a collection trough body connected to the channel port, and the bottom is inclined; The vertical transition section 342 extends from the end of the laterally connected inclined section, downward along the inner wall of the razor body 4, and is designed with segmented hinges or flexible bellows to adapt to the internal space limitations. The end is connected to the entrance of the storage bin 321 through a quick-release buckle. This bending setting can save space while ensuring the channel effect.

[0043] The storage bin 321 is a detachable filter box structure. The box body is molded from transparent ABS plastic, and air intake balance holes are provided on the side wall to prevent negative pressure adsorption from being blocked. Multiple filter components are arranged inside the filter box.

[0044] As Figure 5 shown, the storage part 32 is further provided with a negative pressure collection system 322. The negative pressure collection system 322 is a blower arranged on one side of the storage bin 321. The negative pressure collection system 322 is used to suck the contents in the collection part 31 and the conduction path 34 into the storage bin 321.

[0045] Furthermore, the collection device 3 further includes a vibration mechanism 33. The vibration mechanism 33 is used to connect the suction accessory 22. The vibration mechanism 33 is mechanically connected to the suction accessory 22 and can be implemented in any of the following forms: Piezoelectric ceramic vibrator: directly fixed to the end of the cylindrical adsorption net through a support member 13, and uses the inverse piezoelectric effect to generate high-frequency and micro-amplitude vibrations; Linear motor module: integrated inside the cylindrical cover body, connected to the side wall of the adsorption net through an elastic connecting rod, and drives the adsorption net to vibrate axially or radially; Eccentric wheel mechanism: driven by a micro-motor to rotate the eccentric wheel, and transmits the centrifugal force to the adsorption net through an insulating transmission rod.

[0046] Working principle The first step: Shaving and real-time adsorption When the user turns on the razor: The two sealing plates 313 open the collection channel 312. One of the sealing plates 313 seals the channel opening, and the other sealing plate 313 is located below the top cover plate 314. At this time, the two groups of parallel reciprocating cutter heads 121 vibrate at high frequency under the drive of the drive mechanism, cutting the beard and debris that penetrate into the shaving chamber 1. The second step: Debris stripping and closed collection When shaving is over: The electrostatic adsorption device 2 is powered off, and the adsorption force is released; the two sealing plates 313 close the collection channel 312, and the side wall collection channel 312 is closed to form a sealed space, and the conduction opening 3111 is opened. The vibration mechanism 33 is started, driving the adsorption net to vibrate at high frequency and with a small amplitude, so that the debris falls off; The third step: Debris directional transfer The negative pressure collection system 322 is activated, and debris is sucked into the storage bin 321 through the guiding passage (the horizontal connection section 341 and the vertical transition section 342); the anti-sticking coating on the inner wall of the guiding passage 34 ensures residue-free transfer of the debris; after the debris enters the detachable storage bin 321, it is intercepted by the filter screen and adsorbed and fixed by the sticky plate 3211 in sequence.

[0047] Step 4: User maintenance The user presses the release key to take out the storage bin 321, replaces and cleans the sticky plate 3211, reinstalls the storage bin 321 after cleaning, and the sealing plate 313 returns to the initial position to prepare for the next use.

[0048] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
