Cutter having 360° following foil and shaver

Abstract

The present invention provides a cutter having a 360° following foil and a shaver. The cutter having a 360° following foil comprises a combined foil. The combined foil is formed by connecting and assembling three or more foils, each foil being capable of floating or tilting under a force. A foil on an inner side can float or tilt with an adjacent foil on an outer side upon being subjected to a force. The foils of the present invention can not only float independently, but also float in a linked mode, and can flexibly rotate in all directions, enabling a close fit to facial contours, comprising parts such as the cheeks, the chin, and the neck. During shaving, different facial contours can be easily adapted to without extensively moving the shaver body, thereby effectively improving the fit and comfort of shaving.

Description

A cutter head with 360° follow-up cutter net and a shaver TECHNICAL FIELD

[0001] The present application belongs to the technical field of shavers, and relates to a cutter head with 360° follow-up cutter net and a shaver. BACKGROUND

[0002] The cutter net of the current rotary shaver is integrated and can only float up and down. During shaving, due to the complex and diverse facial contours of the human face, including different radii and concave-convex regions of the cheeks, chin, neck, etc., the fixed shaver net is difficult to closely adhere to the skin surface at all times. This results in that during shaving, part of the beard may not be effectively shaved, and the user needs to repeatedly adjust the angle and force of the shaver, which not only reduces the shaving efficiency, but also easily causes problems such as pulling the beard and scratching the skin due to the close adhesion of the shaver net to the skin, affecting the user's shaving experience.

[0003] The existing CN216831008U discloses a cutter head floating mechanism and a shaver, comprising: a moving cutter assembly, including a first moving cutter group and a second moving cutter group; a transmission assembly, including at least a first transmission member, a second transmission member and a third transmission member, the third transmission member is connected with the first transmission member and the second transmission member respectively, the first transmission member and the second transmission member are connected with the first moving cutter group and the second moving cutter group respectively; an elastic assembly, including a first elastic member and a second elastic member, the two ends of the first elastic member are respectively abutted with the first transmission member and the third transmission member, the two ends of the second elastic member are respectively abutted with the second transmission member and the third transmission member; a cutter net assembly, including a first cutter net and a second cutter net, respectively provided with a first accommodating groove and a second accommodating groove, the first moving cutter group and the second moving cutter group are at least partially arranged in the first accommodating groove and the second accommodating groove respectively. The cutter head floating mechanism of the present application can independently float between the cutter nets and the moving cutter groups, has good face adhesion, and has high shaving quality. However, the cutter net floating in the present application can only float up and down and independently float, and the floating structure is complex, the floating of the cutter net and the cutter head is limited, and the adhesion of the cutter net to the face of the user is not ideal during use. SUMMARY

[0004] To solve the above technical problems, the present application provides a cutter head with 360° follow-up cutter net and a shaver, each cutter net can not only independently float, but also follow 360°, effectively improving the adhesion and comfort of shaving, reducing the dead angle of shaving, improving the cleanliness of shaving, reducing the processing difficulty of the cutter net, and improving the processing efficiency.

[0005] The technical scheme adopted by the present application is:

[0006] A cutter head with a 360° follow-up cutter head includes a combined cutter head, which is formed by connecting and assembling three or more cutter heads. Each cutter head can float or tilt under force, and the inner cutter head can float or tilt under force with the adjacent outer cutter head.

[0007] Furthermore, the inner blade mesh is installed within the receiving ring of the adjacent outer blade mesh and is configured with a clearance fit.

[0008] Furthermore, adjacent blades are positioned and assembled using protrusions and grooves to prevent independent rotation of the blades, while the floating stroke of the blades is less than the engagement depth of the protrusions and grooves.

[0009] Furthermore, the outer ring of the innermost blade net, the inner ring and outer ring of the other blade nets are all provided with flanges. The inner ring flange of the outer blade net rests on the outer ring flange of the adjacent inner blade net, thereby achieving follow-up movement. Moreover, the rotation of the moving blades in each moving net is not affected by the blade net.

[0010] Furthermore, each blade foil is equipped with a corresponding moving blade assembly, which includes a bearing and a blade. The blade is fixed on the bearing and works in conjunction with the corresponding blade foil for shaving.

[0011] Furthermore, the bearings are connected by snap-fit ​​or through transmission components.

[0012] Furthermore, elastic elements are provided between the bearing bushes or between the bearing bushes and the transmission components.

[0013] Furthermore, the innermost blade mesh is fixed to the bearing of the corresponding moving blade assembly by a positioning pin.

[0014] Furthermore, the outermost moving blade assembly, except for the innermost moving blade assembly, is provided with several positioning protrusions for centering in conjunction with the inner wall of the corresponding blade net.

[0015] Furthermore, the blade mesh is a mesh module or a functional module.

[0016] A shaver includes a body and a drive mechanism, wherein the drive mechanism is disposed inside the body and a shaver head with a 360° follow-up blade net is mounted on the drive mechanism.

[0017] The beneficial effects of this invention are:

[0018] 1. 360° Floating Blade: Each blade can float individually or in conjunction with others, and can rotate flexibly in all directions to closely conform to the contours of the face, including the cheeks, chin, and neck. This allows for easy adaptation to different facial contours without requiring extensive movement of the shaving body during shaving, effectively improving the fit and comfort of the shave.

[0019] 2. Dynamically adjustable foil: The foil can not only float up and down, but also swing left and right, or tilt, within a certain angle to better adapt to the unevenness of the face. During shaving, the head can automatically adjust the angle according to the undulation of the skin to ensure close contact between the foil and the face, reduce dead spots, and improve the cleanliness of the shave.

[0020] 3. Adaptive shaving: The shaving head is equipped with an elastic element. When the shaving head comes into contact with the face, the elastic element will automatically adjust the fit between the foil and the skin according to the pressure on the face. This allows the foil to better adapt to different facial pressure points, ensuring a clean shave while avoiding excessive pressure on the skin.

[0021] 4. Sectional shaving: The mesh size of each foil can be different or the same. A fine mesh is primarily used for shaving short, fine hairs, precisely capturing and cutting the tiny hairs close to the skin's surface, effectively preventing nicks and cuts. A relatively larger mesh is suitable for handling longer and coarser hairs; the larger mesh reduces hair tangling on the foil, making the shaving process smoother.

[0022] 5. It can be modularly designed to form blade mesh assemblies with different thicknesses and groove shapes. Combinations can be made according to requirements to meet the needs of different customers and consumers, reducing product development cycles and time, improving production efficiency, and lowering costs.

[0023] 6. Easy to process: Compared with integrated multi-ring blade nets, the mold process and processing difficulty of blade nets are greatly reduced, the manufacturing process is simplified, the processing difficulty is reduced, the processing efficiency is improved, the material consumption is reduced, and the manufacturing precision and quality of products are improved at the same time.

[0024] 7. Modular design: The blade mesh can be composed of mesh modules of different thicknesses and groove shapes, or combined with functional modules for different purposes, such as antibacterial modules, heating modules, cleaning modules, skin detection modules, and odor modules. This modular design allows for customization to meet the needs of different customers and consumers, reducing product development time and improving production efficiency while lowering costs.

[0058] Example 1

[0059] Referring to Figures 1-13, this embodiment provides a cutter head with a 360° follow-up cutter head, including a combined cutter head, which is formed by connecting and assembling three or more cutter heads. Each cutter head can float or tilt under force, and the inner cutter head can float or tilt following the force applied to the adjacent outer cutter head. The inner cutter head is installed within the receiving ring of the adjacent outer cutter head with a clearance fit. Adjacent cutter heads are positioned and assembled by a protrusion and groove fit to prevent independent rotation of the cutter heads, and the floating stroke of the cutter head is less than the fitting depth of the protrusion and groove. The outer ring of the innermost cutter head, the inner ring and outer ring of the other cutter heads are all provided with flanges. The inner ring flange of the outer cutter head rests on the outer ring flange of the adjacent inner cutter head, thereby achieving follow-up, and the rotation of the moving cutter in each cutter head is not affected by the cutter head.

[0060] In this embodiment, each blade holder is equipped with a corresponding moving blade assembly. Each moving blade assembly includes a bearing and a blade. The blade is fixed to the bearing, and the bearings are connected by snap-fit ​​connections or via a transmission component. Elastic elements are provided between the bearings or between the bearings and the transmission component. The blade engages with the corresponding blade holder for shaving. The innermost blade holder is fixed to the bearing of the corresponding moving blade assembly via a positioning post. The outermost moving blade assemblies, excluding the innermost one, all have several positioning protrusions for centering and engaging with the inner wall of the corresponding blade holder.

[0061] This embodiment takes a configuration of three blade meshes as an example. The combined blade meshes include a first blade mesh 51, a second blade mesh 52, and a third blade mesh 53; correspondingly, a first moving blade group 54, a second moving blade group 55, and a third moving blade group 56 are configured; it also includes a first elastic element 58, a second elastic element 59, and a transmission element 57. In this embodiment, all three blade meshes are mesh modules.

[0062] In this embodiment, the first blade net 51, the second blade net 52, and the third blade net 53 can float or tilt individually, or they can float and tilt in conjunction with each other. The first blade net 51, the second blade net 52, and the third blade net 53 can use blade nets of different thicknesses and groove shapes to achieve both coarse and fine shaving. The blade nets are independent and replaceable. The blade nets can be configured such that the mesh of the third blade net 53 is larger, which facilitates the entry of long hairs and is used for shaving long beards. The second blade net 52 is used for coarse shaving, with larger meshes for faster hair entry. The first blade net 51 is used for fine shaving, with a thinner mesh for better shaving and a cleaner shave. The mesh shape and size of the first blade net 51, the second blade net 52, and the third blade net 53 can be set and combined according to requirements, and the combination method is not limited to the above methods. The first, second, and third blade nets are all made of metal.

[0063] The combination and stacking method of the blade nets in this embodiment is as follows: the blade nets are stacked and combined in a step-by-step manner by the outer blade nets nesting the inner blade nets. The function of this method is to limit and constrain the inner blade nets by the inner diameter and bottom of the outer blade nets, thereby preventing them from detaching from the outer blade nets. That is, the inner ring flange 60 of the third blade net 53 is stacked on the outer ring flange 61 of the second blade net 52, and the inner ring flange of the second blade net 52 is stacked on the outer ring flange of the first blade net 51.

[0064] The inner blade mesh has protrusions extending from its outer wall that are positioned within the inner annular grooves of the outer blade mesh. This progressively prevents rotation; specifically, the protrusions on the first blade mesh 51 are positioned within the inner annular grooves of the second blade mesh 52, and the protrusions 63 of the second blade mesh 52 are positioned within the inner annular grooves 62 of the third blade mesh 53. Of course, these protrusions should never detach from the inner annular grooves during the blade assembly's floating process; that is, the floating stroke should be less than the mating depth between the protrusions and the inner annular grooves.

[0065] In this embodiment, the first moving cutter group 54 includes a first blade 541 and a first bearing shell 542, with the first blade 541 mounted on the first bearing shell 542; the second moving cutter group 55 includes a second blade 551 and a second bearing shell 552, with the second blade 551 mounted on the second bearing shell 552; the third moving cutter group 56 includes a third blade 561, a connecting member 562, and a third bearing shell 563, with the third blade 561 mounted on the third bearing shell 563 via the connecting member 562. The blades in each moving cutter group are made of metal; the transmission components and bearing shells are generally made of plastic, but can also be made of metal or other materials; the assembly of the blades and bearing shells in each moving cutter group can be achieved through conventional injection molding, welding, riveting, or other processes.

[0066] Power is provided by the machine body and transmitted to the third moving tool group 56 through the cutter shaft of the machine body. The third moving tool group 56 transmits power to the other moving tool groups through mechanical contact. This transmission can be achieved through a transmission component or through direct connection. In this embodiment, the third moving blade assembly 56 transmits power to the second moving blade assembly 55 via a latch. Specifically, the third bearing shell 563 is provided with a long latch 564, and the corresponding second bearing shell 552 has a first latch 553 on its horizontal surface. The long latch 564 passes through the first latch 553 and engages with each other, thereby enabling the third moving blade assembly 56 to drive the second moving blade assembly 55 to rotate. The third moving blade assembly 56 is also connected to the transmission component 57 via a latch, and the transmission component 57 is also connected to the first moving blade assembly 54 via contact. Specifically, the upper end of the transmission component 57 is in direct contact with the first bearing shell 542, and the transmission is achieved through a special-shaped structure. The lower outer wall of the transmission component 57 is provided with a latch 571, and the corresponding third bearing shell 563 has a second latch 565 on its wall surface. After the latch 571 engages with the second latch 565, the third moving blade assembly 56 can drive the first moving blade assembly 54 to rotate. A first elastic element 58 is provided between the interior of the transmission component 57 and the third bearing 563, and a second elastic element 59 is provided between the lower surface of the second bearing 552 and the third bearing 563. Floating or tilting is achieved through the first elastic element 58 and the second elastic element 59.

[0067] The centering structure of the outer moving blade groups, namely the second moving blade group 55 and the third moving blade group 56, is as follows: the second moving blade group 55 and the third moving blade group 56 are respectively centered by three positioning protrusions 64 extending from the main body of the moving blade group, which cooperate with the inner wall of the outer ring of the corresponding second blade net 52 and the third blade net 53, so that the moving blade group can rotate around the central axis within the blade net. At the same time, the first blade net 51 is installed on the first bearing 542 of the first moving blade group 54 through positioning pins, and is also centered.

[0068] In this embodiment, floating refers to the process where all parts of the blade assembly leave their original positions due to force, and then return to their original positions after the force disappears or falls below the supporting elasticity provided by the circular blades themselves. Tilting refers to the process where a part of the blade assembly tilts due to force leaving its original position, and then returns to its original position after the force disappears or falls below the supporting elasticity provided by the circular blades themselves. Linkage can be categorized into linked floating, linked tilting, linked floating, and tilting, etc. Essentially, after the outer blade assembly is subjected to force, the structure of the aforementioned combination and stacking of blade nets drives the movement of its inner blade net. Since the face is curved during shaving, forces are generated in multiple directions. Therefore, the inner blade assembly will float, tilt, or drive even more inner blade assemblies to move depending on the force applied. Figure 7 shows the movement of each blade net under three different directional forces. Of course, the more blade assemblies combined, the more combinations of movement occur, accommodating more forces generated during shaving and achieving a better shaving effect.

[0069] Referring to Figure 13, with 3 sets of blades, there are a total of 8 motion effects. As the number of blade sets increases, the motion of the entire circular blade will increase exponentially (2... n The more blades there are, the better the round blades will provide for a close shave.

[0070] The specific assembly steps in this embodiment are as follows:

[0071] 1) The first blade net 51 and the first moving blade group 54 are assembled by placing the positioning post 511 in the blade net into the positioning hole of the first bearing 542, as shown in Figure 14.

[0072] 2) The first blade 51 is placed inside the receiving ring of the second blade 52 (the two are fitted with a clearance and have a suitable gap), and the protrusion extending from the outer wall of the first blade 51 is placed inside the inner ring groove of the second blade 52 (the function of the two features is to prevent the independent rotation of the inner blades) to realize the assembly of the first blade 51 and the second blade 52, as shown in Figure 15.

[0073] 3) The second blade 52 is placed in the receiving ring of the third blade 53, and the protrusion extending from the outer wall of the second blade 52 is placed in the inner ring groove of the third blade 53 to realize the assembly of the first and second blades and the third blade 53, as shown in Figure 16.

[0074] 4) The third moving cutter group 56 is provided with three sets of buckles and has space for placing the first elastic member 58. The first elastic member 58, the transmission member 57 and the third moving cutter group 56 are connected by the buckle cooperation between the third moving cutter group 56 and the transmission member 57, as shown in Figure 17 below.

[0075] 5) The third moving blade assembly 56 is provided with three sets of buckles and has space for placing the second elastic member 59. The second elastic member 59, the second moving blade assembly 55 and the third moving blade assembly 56 are connected by the buckle cooperation between the third moving blade assembly 56 and the second moving blade assembly 55, as shown in Figure 18.

[0076] 6) The second and third moving blade groups are respectively positioned within the second and third blade nets by three positioning protrusions extending from the main body of the moving blade group and engaging with the inner walls of the outer rings of the second and third blade nets, as shown in Figure 19; the first elastic element 58 generates elastic force and transmits it to the first moving blade group 54 through the transmission element 57 to provide the first moving blade group 54 with the first blade net 51 with elastic force; the second elastic element 59 generates elastic force and transmits it to the second moving blade group 55 to provide the second moving blade group 55 with the second blade net 52 with elastic force. The three or more blade groups of the present invention can realize the combination and superposition of multiple blade groups so that a single set of circular blades can achieve good surface-applying function, while ensuring that the rotation of the moving blades in each blade group is not affected. Figure 20 is a schematic diagram of the combination of the circular blade as a whole and each blade group.

[0077] This invention features a 360° floating shaving head: each shaving head can float individually or in conjunction with others, rotating flexibly in all directions to closely conform to facial contours, including the cheeks, chin, and neck. This allows for easy adaptation to different facial contours without requiring extensive movement of the shaver during shaving, effectively improving shaving fit and comfort. The dynamically adjustable shaving head can not only float up and down but also swing left and right (tilting) at certain angles to better adapt to uneven facial contours. During shaving, the shaving head automatically adjusts its angle according to skin contours, ensuring close contact between the shaving head and the face, reducing blind spots, and improving a clean shave. The self-adaptive shaving head incorporates an elastic element that automatically adjusts the fit between the shaving head and the skin based on facial pressure when the shaver contacts the face. This allows the shaving head to better adapt to different facial pressure points, ensuring a clean shave while avoiding excessive pressure on the skin. Sectional shaving allows for different or identical mesh sizes for each blade. Fine mesh blades are primarily used for shaving short, fine hairs, precisely capturing and cutting even the smallest hairs close to the skin, effectively preventing chafing. Larger mesh blades are suitable for longer, coarser hairs, reducing tangling and making shaving smoother. Modular designs allow for the creation of blade sets with varying thicknesses and groove shapes. Custom combinations cater to diverse customer needs, reducing product development time and increasing production efficiency while lowering costs. Compared to integrated multi-ring shaving covers, the mold and manufacturing processes for blades are significantly simplified, reducing processing difficulty, increasing efficiency, and decreasing material consumption, while simultaneously improving product precision and quality.

[0078] Example 2

[0079] Referring to Figure 21, the difference between this embodiment and Embodiment 1 is that the second razor foil 52 in this embodiment uses an antibacterial module 65. The antibacterial module can be a coating containing antibacterial materials (such as nano-silver particles) or a separate small container filled with an antibacterial agent. If it is a coating, the nano-silver particles can be evenly distributed on the module surface. When bacteria come into contact with it, the silver ions interact with the bacterial cell wall or cell membrane, destroying the bacterial structure and thus achieving an antibacterial effect. If it is an antibacterial agent container, the antibacterial agent can be slowly released to form an antibacterial environment around the razor foil. The antibacterial module 64 reduces bacterial growth, which is very important for skin health. Because bacteria easily remain in razors after use, if not controlled, it may cause skin infections and other problems, especially for users with sensitive skin.

[0080] The remaining structures and functions can be referred to in Embodiment 1.

[0081] Example 3

[0082] Referring to Figure 22, the difference between this embodiment and Embodiment 1 is that the second shaver foil 52 in this embodiment uses a heating module 66. The heating module 66 contains small heating elements, such as heating wires, and a temperature sensor. When the heating function is activated, the heating wires begin to work, raising the surface temperature of the shaver foil to a suitable temperature (e.g., 30-40 degrees Celsius). The temperature sensor can monitor the temperature in real time, ensuring that the temperature remains within a safe range to avoid burns to the skin. When using the shaver in winter, the increased warmth of the shaver foil reduces the cold sensation of the blades contacting the user's facial skin, making the beard softer and reducing the pulling and discomfort during shaving, thus making the shaving process more comfortable.

[0083] The remaining structures and functions can be referred to in Embodiment 1.

[0084] Example 4

[0085] Referring to Figure 23, the difference between this embodiment and Embodiment 1 is that the first blade foil 51 in this embodiment uses a massage module 67. The massage module 67 is a module with a massage function, and it has raised bumps, which can be a rolling ball or a roller. When the blade head moves on the skin surface, these bumps can provide a slight massage effect without scratching the skin. Firstly, it improves the user experience: using the massage function while shaving can help relax facial muscles, reduce the tightness and discomfort that may occur during shaving, and provide users with a more comfortable and pleasant shaving experience. Secondly, it promotes blood circulation: the massage function helps promote blood circulation in the face and neck, which is beneficial for improving skin metabolism, reducing signs of fatigue, and enhancing skin health. Long-term use may help make the skin look healthier and more vibrant.

[0086] The remaining structures and functions can be referred to in Embodiment 1.

[0087] Example 5

[0088] Referring to Figure 24, the difference between this embodiment and Embodiment 1 is that the second shaving foil 52 in this embodiment uses a skin detection module 68. The skin detection module 68 can include microsensors, such as capacitive sensors or optical sensors. Capacitive sensors can detect skin moisture and oil content, while optical sensors can detect parameters such as skin roughness. The data collected by these sensors can be analyzed by a built-in chip, and then skin condition information (such as whether it is dry, whether there are signs of inflammation, etc.) is transmitted to a connected device (such as a mobile application). Users can adjust their shaving method or select a suitable shaving product based on the skin detection results. For example, if dry skin is detected, the user can use a moisturizing product before shaving, or choose a shaving foil module with better lubrication.

[0089] The remaining structures and functions can be referred to in Embodiment 1.

[0090] Example 6

[0091] Referring to Figure 25, the difference between this embodiment and Embodiment 1 is that the second foil 52 in this embodiment uses a scent module 69. The scent module 69 has a small fragrance storage chamber with tiny ventilation holes.
