Description

Technical Field

[0001] The invention belongs to the technical field of shavers and relates to a cutter head with a modular combined floating cutter net and a shaver. Background Art

[0002] The blade net of current rotary shavers is integrated and can only float up and down. During the shaving process, due to the complex and diverse facial contours of the human face, including areas with different curvatures and bumps such as the cheeks, chin, and neck, it is difficult for the fixed shaver net to always fit closely to the skin surface. This results in part of the beard not being effectively shaved during shaving, requiring the user to repeatedly adjust the angle and strength 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 loose fit of the shaver net to the skin, affecting the user's shaving experience.

[0003] The existing CN216831008U discloses a blade floating mechanism and a razor, including: a moving blade assembly, including a first moving blade group and a second moving blade 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 to the first transmission member and the second transmission member respectively, and the first transmission member and the second transmission member are connected to the first moving blade group and the second moving blade 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 against the first transmission member and the third transmission member, and the two ends of the second elastic member are respectively against the second transmission member and the third transmission member; a knife net assembly, including a first knife net and a second knife net, respectively provided with a first receiving groove and a second receiving groove, and the first moving blade group and the second moving blade group are at least partially arranged in the first receiving groove and the second receiving groove respectively.

However, the blade net in the application can only float up and down and float alone, and the floating structure is complicated, the floating of the blade net and the blade head is limited, and the blade net does not fit the user's face well when used. The blade net of the razor has a single function and limited shape. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cutter head and a shaver with a modular combination floating knife net. Each knife net can not only float independently, but also move 360°, which effectively improves the fit and comfort of shaving, reduces shaving dead angles, improves the cleanliness of shaving, reduces the processing difficulty of the knife net, improves processing efficiency, and has diversified functions, which can be selected and replaced according to needs.

[0005] The technical solution adopted by the present invention is:

[0006] A cutter head with a modular combined floating knife net comprises a modular combined knife net, wherein the modular combined knife net is formed by connecting and assembling a plurality of mesh modules and a plurality of functional modules, each mesh module and functional module can float or tilt under force, the inner mesh module or functional module can float or tilt with the adjacent outer mesh module or functional module under force, and each mesh module is equipped with a movable knife group.

[0007] Furthermore, the inner mesh module or functional module is installed in the receiving circle of the adjacent outer mesh module or functional module and is arranged with clearance fit.

[0008] Furthermore, adjacent mesh modules, and / or mesh modules and functional modules, and / or functional modules and functional modules are positioned and assembled by means of protrusions and grooves to prevent independent rotation of the knife net, and at the same time, the floating stroke of the mesh module or the functional module is less than the fitting depth of the protrusion and the groove.

[0009] Furthermore, the outer ring of the innermost mesh module or functional module, the inner ring and outer ring of other mesh modules and / or functional modules are all provided with flanges, and the inner ring flange of the outer mesh module or functional module is placed on the outer ring flange of the adjacent inner mesh module or functional module, thereby achieving follow-up movement, and the rotation of the moving knife in each moving net is not affected by the knife net.

[0010] Furthermore, the mesh module includes a combination of two or more of a fine and dense short beard mesh sub-module, a coarse and sparse long beard mesh sub-module, and a special shape mesh sub-module, so as to realize zoned shaving and can realize both fine shaving and coarse shaving at the same time.

[0011] Furthermore, the functional modules include a combination of one or more of an antibacterial module, a heating module, a massage module, a skin detection module, and an odor module.

[0012] Furthermore, the movable knife group includes a bearing and a blade, the blade is fixed on the bearing, the bearings are snap-connected or connected through a transmission member, elastic members are provided between the bearings or between the bearings and the transmission member, and the blade cooperates with the corresponding mesh module for shaving.

[0015] The shaver comprises a body and a driving mechanism, wherein the driving mechanism is arranged in the body and the driving mechanism is mounted with the above-mentioned cutter head with modular combined floating cutter net.

[0016] Beneficial effects of the present invention:

[0017] 1. Modular design, composed of mesh modules of different thicknesses and groove types, and functional modules with different functions, such as antibacterial module, heating module, cleaning module, skin detection module, odor module. Combining according to needs to meet the needs of different customers and consumers can reduce the number and time of product development, improve production efficiency and reduce costs.

[0018] 2. 360° floating knife net: Each mesh module can not only float independently, but also float in linkage. It can rotate flexibly in all directions and can fit the facial contours closely, including cheeks, chin, neck and other parts. There is no need to move the body over a large range when shaving. It can easily adapt to different facial contours, effectively improving the fit and comfort of shaving.

[0019] 3. Dynamically adjust the blade net. The blade net can not only float up and down, but also swing left and right, that is, tilt, and tilt within a certain angle to better adapt to the unevenness of the face. During the shaving process, the blade head can automatically adjust the angle according to the ups and downs of the skin to ensure close contact between the blade net and the face, reduce shaving dead angles, and improve the cleanliness of shaving.

[0020] 4. Adaptive shaving: an elastic part is set inside the blade head. When the shaver touches the face, the elastic part will automatically adjust the fit between the blade net and the skin according to the pressure of the face, so that the blade net can better adapt to different facial pressure points, which can not only ensure the cleanliness of the shaving, but also avoid excessive pressure on the skin.

[0021] 5. Zoned shaving, each mesh module has different meshes, and can adopt a fine mesh design, which is mainly used to shave short and soft beards. It can accurately capture and cut off the fine hair close to the skin surface, effectively avoiding skin scratches. The use of relatively large meshes is suitable for processing longer and coarser beards. Larger meshes can reduce the entanglement of beards on the mesh surface, making the shaving process smoother.

[0022] 6. Easy to process. Compared with the integrated multi-ring knife net, the mold process difficulty and processing difficulty of the mesh module are greatly reduced, the manufacturing process is simplified, the processing difficulty is reduced, the processing efficiency is improved, the consumables are reduced, and the product manufacturing accuracy and quality are improved.

[0040] Embodiment 1

[0041] See also Figure 1-4The present embodiment provides a cutter head with a modular combined floating knife net, including a modular combined knife net, wherein the modular combined knife net is formed by connecting and assembling a plurality of mesh modules and a plurality of functional modules, each mesh module and functional module can float or tilt under force, and the inner mesh module or functional module can float or tilt with the adjacent outer mesh module or functional module after being subjected to force, and each mesh module is configured with a movable knife group. The inner mesh module or functional module is installed in the accommodation circle of the adjacent outer mesh module or functional module and is arranged with clearance fit. Adjacent mesh modules and mesh modules, and\or mesh modules and functional modules, and\or functional modules and functional modules are positioned and assembled by means of protrusions and grooves to prevent the independent rotation of the knife net, and at the same time, the floating stroke of the mesh module or functional module is less than the fitting depth of the protrusion and the groove. The outer ring of the innermost mesh module or functional module, the inner ring and outer ring of other mesh modules and / or functional modules are all provided with flanges, and the inner ring flange of the outer mesh module or functional module is placed on the outer ring flange of the adjacent inner mesh module or functional module, thereby achieving follow-up movement, and the rotation of the moving knife in each moving net is not affected by the knife net.

[0042] The mesh module of the present invention includes a combination of two or more of a fine short beard mesh submodule, a coarse and sparse long beard mesh submodule, and a special shape mesh submodule, so as to realize zoned shaving and simultaneously realize fine shaving and rough shaving. Specifically, the fine short beard mesh submodule is designed for fine and soft short beards, and its mesh is circular, elliptical, polygonal, heterogeneous, etc., and the diameter of the inscribed circle is between 0.3-0.6 mm, which can accurately capture and cut off short beards, making the skin surface smoother after shaving. The coarse and sparse long beard mesh submodule is suitable for longer beards, and the mesh is in a groove shape (the groove shape can be a long strip, a diamond shape, an S shape, a V shape, etc.), with a width of more than 0.2 mm. The larger mesh can reduce the situation where the beard blocks the mesh and improve the shaving efficiency. Special shape mesh submodule: For example, the arc mesh submodule is used to meet the shaving needs of special facial contours (such as the chin and neck curve). Its mesh is distributed along a specific arc track, which can better adapt to the curvature of the skin and reduce shaving dead angles. Of course, the mesh shape and size of each mesh submodule are not limited to the above.

[0043] The functional modules of the present invention include a combination of one or more of an antibacterial module, a heating module, a massage module, a skin detection module, and an odor module.

[0044] The movable knife groups of the present invention all include bearings and blades, the blades are fixed on the bearings, the bearings are connected by snaps or by transmission parts, elastic parts are arranged between the bearings or between the bearings and the transmission parts, and the blades cooperate with the corresponding mesh modules for shaving. The innermost mesh module or functional module is fixed on the bearing of the corresponding movable knife group by a positioning column. The main body of the outer movable knife group is provided with a plurality of positioning protrusions for centering with the inner wall of the corresponding mesh module.

[0045] In this embodiment, three mesh modules are provided as an example. The modular combined knife net includes a first mesh module 51, a second mesh module 52, and a third mesh module 53; correspondingly, a first moving knife group 54, a second moving knife group 55, and a third moving knife group 56 are configured; and a first elastic member 58, a second elastic member 59 and a transmission member 57 are also included.

[0046] In this embodiment, the first mesh module 51, the second mesh module 52, and the third mesh module 53 are respectively a fine short beard mesh submodule, a coarse long beard mesh submodule, and a special shape mesh submodule. The first mesh module 51, the second mesh module 52, and the third mesh module 53 can float or tilt individually or can float and tilt in linkage with each other. The first mesh module 51, the second mesh module 52, and the third mesh module 53 can use knife nets of different thicknesses and different groove types to achieve rough and fine shaving, and the knife nets can be replaced independently of each other. The mesh of the third mesh module 53 is larger, which is conducive to the entry of long beards and is used to shave long beards. The second mesh module 52 is used for rough shaving, with large mesh holes and fast entry of beards. The first mesh module 51 is used for fine shaving, with a thinner knife net, better shaving, and a cleaner shaving. The first, second, and third knife nets are all made of metal.

[0047] The combination and superposition method of the knife net in this embodiment: the mesh modules are superimposed and combined step by step in the manner of an outer mesh module covering an inner mesh module. The function of this method is to limit the inner mesh module through the inner diameter and the bottom of the outer mesh module, thereby preventing it from detaching from the outer mesh module, that is, the inner ring flange 60 of the third mesh module 53 is superimposed on the outer ring flange 61 of the second mesh module 52, and the inner ring flange of the second mesh module 52 is superimposed on the outer ring flange of the first mesh module 51.

[0048] The protrusions extending from the outer wall of the inner mesh module through the knife net are placed in the inner ring groove of the outer mesh module to achieve anti-rotation step by step, that is, the protrusions on the first mesh module 51 are placed in the inner ring groove of the second mesh module 52, and the protrusions 63 of the second mesh module 52 are placed in the inner ring groove 62 of the third mesh module 53. Of course, the corresponding protrusion features should not be separated from the inner ring groove during the floating process of the knife group, that is, the floating stroke is less than the matching depth of the protrusion and the inner ring groove.

[0049] The floating of this embodiment is the process that all parts of the knife group leave their original positions due to force, and return to their original positions after the force disappears or is lower than the supporting elastic force provided by the circular knife itself. The tilting is the process that a part of the knife group leaves its original position due to force and becomes tilted, and returns to its original position after the force disappears or is lower than the supporting elastic force provided by the circular knife itself. The linkage can be divided into linkage floating, linkage tilting, linkage floating and tilting, etc. Its essence is: after the outer knife group is subjected to force, the movement of its inner knife net is driven by the structural limit of the combined superposition of the above-mentioned knife nets. Because the face is curved during shaving, forces in multiple directions will be generated, so the inner knife group will float, tilt or drive the inner knife group to move according to the force situation. The movement of each knife net when subjected to three different directions of force; of course, the more combined knife groups there are, the more movement combinations there are, which can cater to more forces generated by shaving and achieve a better face-fitting effect.

[0050] The modular design of the present invention can form mesh modules of different thicknesses and different groove types, and can also combine functional modules with different functions, such as antibacterial modules, heating modules, cleaning modules, skin detection modules, and odor modules. Combining according to needs can meet the needs of different customers and consumers, which can reduce the number and time of product development, improve production efficiency, and reduce costs. 360° floating knife net: Each mesh module can not only float alone, but also float in linkage, and can be flexibly rotated in all directions, and can fit the facial contours tightly, including cheeks, chins, necks and other parts. When shaving, there is no need to move the body over a large range, and it can easily adapt to different facial contours, effectively improving the fit and comfort of shaving. Dynamically adjust the knife net, the knife net can not only float up and down, but also swing left and right, that is, tilt, and tilt within a certain angle, so as to better adapt to the unevenness of the face. During the shaving process, the knife head can automatically adjust the angle according to the ups and downs of the skin to ensure the close contact between the knife net and the face, reduce shaving dead angles, and improve the cleanliness of shaving. Adaptive face-fitting: elastic parts are set inside the blade head. When the shaver touches the face, the elastic parts will automatically adjust the fit between the blade net and the skin according to the pressure of the face, so that the blade net can better adapt to different facial pressure points, which can not only ensure the cleanliness of shaving, but also avoid excessive pressure on the skin. Partition shaving: the mesh of each mesh module is different, and a fine mesh design can be adopted. It is mainly used to shave short and soft beards. It can accurately capture and cut off the fine hair close to the skin surface, effectively avoiding skin scratches. Relatively large meshes are suitable for processing longer and coarser beards. Larger meshes can reduce the entanglement of beards on the mesh surface, making the shaving process smoother. Easy to process: compared with the integrated multi-ring blade net, the mold process difficulty and processing difficulty of the mesh module are greatly reduced, the manufacturing process is simplified, the processing difficulty is reduced, the processing efficiency is improved, the consumables are reduced, and the product manufacturing precision and quality are improved.

[0051] Embodiment 2

[0052] See also Figure 5 , the difference between this embodiment and the first embodiment is that the modular combined knife net described in this embodiment includes a first mesh module 51, an antibacterial module 64, and a third mesh module 53. The antibacterial module can be a coating containing antibacterial materials (such as nanosilver particles) or an independent small container containing an antibacterial agent. If it is a coating, the nanosilver particles can be evenly distributed on the surface of the module. When bacteria come into contact, the silver ions will interact with the cell wall or cell membrane of the bacteria to destroy the structure of the bacteria, thereby achieving an antibacterial effect. If it is an antibacterial agent container, the antibacterial agent can form an antibacterial environment around the razor net by slowly releasing it. The antibacterial module 64 can reduce bacterial growth, which is very important for skin health. Because the razor is prone to residual bacteria after use, if it is not controlled, it may cause skin infections and other problems, especially for some users with sensitive skin.

[0053] The remaining structures and functions can refer to those described in the first embodiment.

[0054] Embodiment 3

[0055] See also Figure 6 The difference between this embodiment and the first embodiment is that the modular combined blade net described in this embodiment includes a first mesh module 51, a heating module 65, and a third mesh module 53. The heating module 65 has a small heating element inside, such as a heating wire, and a temperature sensor. When the heating function is turned on, the heating wire starts to work and raises the surface temperature of the razor net to a suitable temperature (for example, 30-40 degrees Celsius). The temperature sensor can monitor the temperature in real time to ensure that the temperature is within a safe range to avoid scalding the skin. When using a razor in winter, the icy feeling of the blade contacting the user's facial skin is reduced. The warmer razor net can make the beard softer, reduce the pulling and discomfort during shaving, and make the shaving process more comfortable.

[0056] The remaining structures and functions can refer to those described in the first embodiment.

[0057] Embodiment 4

[0058] See also Figure 7, the difference between this embodiment and the first embodiment is that the modular combined knife net described in this embodiment includes a massage module 66, a second mesh module 52, and a third mesh module 53. The massage module 66 uses a module with a massage function, which has protruding bumps, which can be a rolling sphere or a roller. It can also be a protruding bump. When the knife head moves on the surface of the skin, these protrusions can play a slight massage role without scratching the skin. First, to improve the user experience: using the massage function when shaving can help relax facial muscles, reduce the skin tightness and discomfort that may occur during the shaving process, and provide users with a more comfortable and pleasant care experience. Second, to promote blood circulation: The massage function helps to promote blood circulation in the face and neck, which has certain benefits for improving skin metabolism, reducing signs of fatigue and enhancing skin health. Long-term use may help make the skin look healthier and more energetic.

[0059] The remaining structures and functions can refer to those described in the first embodiment.

[0060] Embodiment 5

[0061] See also Figure 8 , the difference between this embodiment and the first embodiment is that the modular combined knife net described in this embodiment includes a first mesh module 51, a skin detection module 67, and a third mesh module 53, and the skin detection module 67 may include a micro sensor, such as a capacitive sensor or an optical sensor. Capacitive sensors can detect the moisture and oil content of the skin, while optical sensors can detect parameters such as the roughness of the skin. The data collected by these sensors can be analyzed by a built-in chip, and then the skin status information (such as whether it is dry, whether there are signs of inflammation, etc.) is transmitted to a device connected thereto (such as a mobile phone application). The user can adjust the shaving method or choose a suitable shaving product based on the results of the skin detection. For example, if dry skin is detected, the user can use a moisturizing product before shaving, or choose a razor net module with better lubrication properties.

[0062] The remaining structures and functions can refer to those described in the first embodiment.

[0063] Embodiment 6

[0064] See also Fig. 9The difference between this embodiment and the first embodiment is that the modular combined knife net described in this embodiment includes a first mesh module 51, a smell module 68, and a third mesh module 53. The smell module 68 has a small fragrance storage chamber inside, and the storage chamber has tiny air holes. The fragrance can be a fragrance with different effects such as soothing and refreshing, such as lavender fragrance for soothing emotions and mint fragrance for refreshing. When using the razor, the smell of the fragrance will slowly emit with the movement of the hand. Provide users with a pleasant shaving experience, especially when shaving in the morning, the fresh and pleasant smell can help users start a good day.
