Description

Technical Field

[0001] The invention belongs to the technical field of shavers and relates to a cutter head with a 360-degree follow-up 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. The blade nets and the moving blade groups of the blade floating mechanism of the present application can float independently, have good facial fit, and high shaving quality. However, the blade net in the application can only float up and down and float alone, and the floating structure is complex, 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 in use. 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 360° follow-up cutter net. Each cutter net can not only float independently, but also follow 360°, which effectively improves the fit and comfort of shaving, reduces shaving dead angles, improves the cleanliness of shaving, reduces the difficulty of cutting net processing, and improves processing efficiency.

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

[0006] A cutter head with a 360° follow-up cutter net comprises a combined cutter net, wherein the combined cutter net is formed by connecting and assembling three or more cutter nets, each of which can float or tilt under force, and the inner cutter net can float or tilt after the adjacent outer cutter net is subjected to force.

[0007] Furthermore, the inner knife net is installed in the accommodating circle of the adjacent outer knife net and is arranged with clearance fit.

[0008] Furthermore, two adjacent knife nets are positioned and assembled by the protrusions and the grooves to prevent the knife nets from rotating independently, and at the same time, the floating stroke of the knife net is smaller than the matching depth of the protrusions and the grooves.

[0009] Furthermore, the outer ring of the innermost knife net, the inner ring and outer ring of other knife nets are all provided with flanges, and the inner ring flange of the outer knife net is placed on the outer ring flange of the adjacent inner knife net, 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, each knife net is equipped with a corresponding moving knife group, and the moving knife group includes a bearing bush and a blade, and the blade is fixed on the bearing bush, and the blade cooperates with the corresponding knife net for shaving.

[0011] Furthermore, the bearing shells are connected by snap-fit ​​connection or through transmission parts.

[0012] Furthermore, an elastic member is arranged between the bearing shells or between the bearing shells and the transmission member.

[0013] Furthermore, the innermost knife net is fixed on the bearing bush of the corresponding moving knife assembly through a positioning column.

[0014] Furthermore, the main bodies of the outer layer movable knife groups except the innermost movable knife group are all provided with a plurality of positioning protrusions for centering in cooperation with the inner wall of the corresponding knife net.

[0015] The shaver comprises a body and a driving mechanism, wherein the driving mechanism is arranged in the body and the above-mentioned blade head with a 360-degree follow-up blade net is installed on the driving mechanism.

[0016] Beneficial effects of the present invention:

[0017] 1. 360° floating blade net: Each blade net 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.

[0018] 2. 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.

[0019] 3. 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.

[0020] 4. For zoned shaving, the mesh of each blade net can be different or the same. The blade net adopts fine mesh, 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 relatively large mesh is suitable for processing long and coarse beards. The larger mesh can reduce the entanglement of beards on the mesh surface, making the shaving process smoother.

[0021] 5. It can be designed in combination to form knife net groups of different thicknesses and different groove types. 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.

[0022] 6. Easy to process. Compared with the integrated multi-ring knife net, the mold process difficulty and processing difficulty of the knife net 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.

[0051] Embodiment 1

[0052] See also Figure 1-13 This embodiment provides a cutter head with a 360° follow-up knife net, including a combined knife net, which is formed by connecting and assembling 3 or more knife nets, each of which can float or tilt under force, and the inner knife net can float or tilt after the adjacent outer knife net is subjected to force. The inner knife net is installed in the accommodating circle of the adjacent outer knife net and is arranged with clearance fit. The two adjacent knife nets are positioned and assembled by the protrusions and grooves to prevent the independent rotation of the knife nets, and the floating stroke of the knife net is less than the fitting depth of the protrusions and grooves. The outer ring of the innermost knife net, the inner ring and the outer ring of the other knife nets are all provided with flanges, and the inner ring flange of the outer knife net is placed on the outer ring flange of the adjacent inner knife net, so as to achieve follow-up, and the rotation of the moving knife in each moving net is not affected by the knife net.

[0053] In this embodiment, each knife net is equipped with a corresponding moving knife group, and the moving knife group includes a bearing and a blade, and the blade is fixed on the bearing. The bearings are connected by snaps or through transmission parts. Elastic parts are provided between the bearings or between the bearings and the transmission parts. The blade cooperates with the corresponding knife net for shaving. The innermost knife net is fixed to the bearing of the corresponding moving knife group through a positioning column. The main body of the outer layer moving knife group except the innermost moving knife group is provided with a plurality of positioning protrusions for centering with the inner wall of the corresponding knife net.

[0054] In this embodiment, three knife nets are provided as an example. The combined knife net includes a first knife net 51, a second knife net 52, and a third knife net 53; correspondingly, a first movable knife group 54, a second movable knife group 55, and a third movable knife group 56 are configured; and a first elastic member 58, a second elastic member 59 and a transmission member 57 are also included.

[0055] In this embodiment, the first knife net 51, the second knife net 52, and the third knife net 53 can float or tilt independently or can float and tilt in linkage with each other. The first knife net 51, the second knife net 52, and the third knife net 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 knife net can be set so that the mesh of the third knife net 53 is larger, which is conducive to the entry of long beards and is used to shave long beards. The second knife net 52 is used for rough shaving, with large mesh and fast entry of beards. The first knife net 51 is used for fine shaving, with a thinner knife net, better shaving, and a cleaner shaving. The mesh shape and mesh size of the first knife net 51, the second knife net 52, and the third knife net 53 can be set and matched according to needs, and the combination method is not limited to the above method. The first, second, and third knife nets are all made of metal.

[0056] The combination and superposition method of the knife nets in this embodiment: the knife nets are superimposed and combined step by step in the manner of an outer knife net covering an inner knife net. The function of this method is to limit the inner knife net through the inner diameter and the bottom of the outer knife net, thereby preventing it from escaping from the outer knife net, that is, the inner ring flange 60 of the third knife net 53 is superimposed on the outer ring flange 61 of the second knife net 52, and the inner ring flange of the second knife net 52 is superimposed on the outer ring flange of the first knife net 51.

[0057] The inner blade net is placed in the inner ring groove of the outer blade net through the protrusion extending from the outer wall of the blade net, so as to achieve the anti-rotation function step by step, that is, the protrusion on the first blade net 51 is placed in the inner ring groove of the second blade net 52, and the protrusion 63 of the second blade net 52 is placed in the inner ring groove 62 of the third blade net 53. Of course, the corresponding protrusion feature should not be separated from the inner ring groove during the floating process of the blade group, that is, the floating stroke is less than the matching depth of the protrusion and the inner ring groove.

[0058] In this embodiment, the first moving knife group 54 includes a first blade 541 and a first bearing 542, and the first blade 541 is mounted on the first bearing 542; the second moving knife group 55 includes a second blade 551 and a second bearing 552, and the second blade 551 is mounted on the second bearing 552; the third moving knife group 56 includes a third blade 561, a connecting member 562 and a third bearing 563, and the third blade 561 is mounted on the third bearing 563 through the connecting member 562. The blades in each moving knife group are all made of metal; the transmission parts and the bearings are generally made of plastic, and can also be made of metal and other materials; the composition of the blades and bearings in each moving knife group can be realized by conventional injection molding, welding, riveting and other processes.

[0059] The power is provided by the fuselage, and is transmitted to the third movable knife group 56 through the knife shaft of the fuselage. The third movable knife group 56 is transmitted to the other movable knife groups through mechanical contact, which can be transmitted by a transmission member or directly connected. In this embodiment, the buckle of the third movable knife group 56 is transmitted to the second movable knife group 55. Specifically, a long buckle 564 is provided on the third bearing 563, and a first buckle opening 553 is provided on the horizontal surface of the corresponding second bearing 552. The long buckle 564 passes through the first buckle opening 553 and is engaged with each other, so that the third movable knife group 56 can drive the second movable knife group 55 to rotate; the buckle cooperation between the third movable knife group 56 and the transmission member 57 is transmitted to the transmission member 57, and the transmission is transmitted to the first movable knife group 54 by the contact between the transmission member 57 and the first movable knife group 54. Specifically, the upper end of the transmission member 57 and the first bearing 542 are directly contacted and transmitted, and the transmission is connected through a special-shaped structure. A buckle 571 is provided on the outer wall surface of the lower end of the transmission member 57, and a second buckle opening 565 is provided on the wall surface of the corresponding third bearing 563. After the buckle 571 is engaged with the second buckle opening 565, the third movable knife group 56 can drive the first movable knife group 54 to rotate. A first elastic member 58 is arranged between the inside of the transmission member 57 and the third bearing 563 , and a second elastic member 59 is arranged between the lower surface of the second bearing 552 and the third bearing 563 . Floating or tilting is achieved by the first elastic member 58 and the second elastic member 59 .

[0060] The centering structure of the outer movable knife group, i.e., the second movable knife group 55 and the third movable knife group 56 is as follows: the three positioning protrusions 64 extending from the movable knife group body of the second movable knife group 55 and the third movable knife group 56 cooperate with the inner wall of the outer ring of the corresponding second knife net 52 and the third knife net 53 to achieve centering, so that the movable knife group rotates along the central axis in the knife net. At the same time, the first knife net 51 is installed on the first bearing 542 of the first movable knife group 54 through the positioning column, and achieves centering.

[0061] The floating of this embodiment refers to the process in which all parts of the knife group leave their original positions due to force, and return to their original positions after the force disappears or becomes lower than the supporting elastic force provided by the circular knife itself. The tilting refers to the process in which 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 becomes 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. Its essence is: after the outer knife group is subjected to force, the movement of the inner knife net is driven by the structural limitation of the combination and superposition of the above-mentioned knife nets. Because the face is curved during shaving, forces in multiple directions will be generated. Therefore, the inner knife group will float, tilt or drive the inner knife group to move according to the force conditions. Figure 7 It shows the movement of each blade net when subjected to forces in three different directions; of course, the more combined blade groups there are, the more movement combinations there are, which can cater to more shaving forces and achieve a better close-fitting effect.

[0062] See also Fig.13In the case of 3 blade groups, there are 8 kinds of motion effects. As the number of blade groups increases, the motion of the entire circular blade will increase in the form of exponential (2n) growth. Therefore, the more blade groups there are, the better the circular blade will be for close shaving.

[0063] The specific steps of assembling this embodiment are as follows:

[0064] 1) The first knife net 51 and the first moving knife group 54 are assembled by placing the positioning column 511 in the knife net into the positioning hole of the first bearing bush 542. Fig.14 shown.

[0065] 2) The first knife net 51 is placed in the receiving circle of the second knife net 52 (the two have a clearance fit and a suitable gap), and the protrusion extending from the outer wall of the first knife net 51 is placed in the inner circle groove of the second knife net 52 (the function of the feature fit of the two is to prevent the independent rotation of the internal knife net) to realize the assembly of the first knife net 51 and the second knife net 52, such as Fig.15 shown.

[0066] 3) The second knife net 52 is placed in the accommodation circle of the third knife net 53, and the protrusion extending from the outer wall of the second knife net 52 is placed in the inner circle groove of the third knife net 53 to realize the assembly of the first, second and third knife nets 53, such as Fig.16 shown.

[0067] 4) The third movable knife group 56 is provided with three sets of buckles and a space for placing the first elastic member 58. The first elastic member 58, the transmission member 57 and the third movable knife group 56 are connected by the buckle cooperation between the third movable knife group 56 and the transmission member 57, as follows: Fig.17 shown.

[0068] 5) The third movable knife group 56 is provided with three sets of buckles and a space for placing the second elastic member 59. The second elastic member 59, the second movable knife group 55 and the third movable knife group 56 are connected by the buckle cooperation between the third movable knife group 56 and the second movable knife group 55. Fig.18 shown.

[0069] 6) The second and third moving knife groups are respectively placed in the second and third knife nets through the three positioning protrusions extending from the moving knife group body and the inner walls of the outer rings of the second and third knife nets, such as Fig.19 As shown, the first elastic member 58 generates elastic force and transmits it to the first movable knife group 54 through the transmission member 57 to provide elastic force for the first movable knife group 54 to fit the first knife net 51, and the second elastic member 59 generates elastic force and transmits it to the second movable knife group 55 to provide elastic force for the second movable knife group 55 to fit the second knife net 52. The three or more knife groups of the present invention can realize the combination and superposition of multiple knife groups so that a single pair of circular knives can achieve a good surface fitting function, while ensuring that the rotation of the movable knives in each knife group is not affected. Fig. 20It is a schematic diagram of the combination of the circular knife as a whole and each knife group.

[0070] The 360° floating knife net of the present invention: each knife net can not only float independently, but also float in linkage, can rotate flexibly in all directions, can closely fit the facial contour, including the cheeks, chin, neck and other parts, and can easily adapt to different facial contours without moving the body in a large range when shaving, effectively improving the fit and comfort of shaving. Dynamic adjustment of 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, ensure the close contact between the knife net and the face, reduce the shaving dead angle, and improve the cleanliness of shaving. Adaptive shaving, an elastic part is arranged in the knife head, when the razor contacts the face, the elastic part will automatically adjust the fit between the knife net and the skin according to the pressure of the face, so that the knife 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. For zoned shaving, the mesh of each knife net can be different or the same. The knife net adopts fine mesh, 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. It adopts relatively large mesh, which is suitable for processing longer and coarser beards. The larger mesh can reduce the entanglement of the beard on the mesh surface, making the shaving process smoother. It can be designed in combination to form knife net groups with different thicknesses and different groove types. It can be combined according to needs to meet the needs of different customers and consumers, which can reduce the number and time of product development, improve production efficiency and reduce costs. Easy to process, compared with the integrated multi-ring mesh cover, the mold process difficulty and processing difficulty of the knife net 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.
