Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of razor heads, in particular to a novel floating structure of a razor head. Background Art
[0002] There are two main types of blade structures for electric shavers currently on the market. One is that the blade net floats up and down, but does not float (rotate) in other directions; the other is that the blade net can float up and down, and the blade net assembly including the blade net can rotate around a fixed rotation axis.
[0003] The above-mentioned related technologies have the following deficiencies:
[0004] For solution one, its structure is simple, but the blade net can only float up and down, and cannot float close to the face well during shaving.
[0005] For the second solution, based on the fact that the knife net can float up and down in the first solution, a knife net frame is added. The knife net frame can rotate around a fixed rotation axis, and the knife net is installed inside the knife net frame. The knife net frames are set with linkage structures. When one knife net frame receives pressure and moves, the other knife nets maintain the same movement posture. However, for specific angles, such as the position that overlaps with the rotation axis, when the knife net is pressed, the knife net frame cannot float with it, resulting in a poor veneer experience. Utility Model Content
[0006] The main purpose of the utility model is to provide a new floating structure of a razor head, which enables a blade grid frame to float and thus improves the shaving experience.
[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: a new floating structure of a razor blade head, comprising a head cover, a blade net, a blade net frame and a blade head spring piece, and also comprising a positioning frame, the blade net frame is clamped on the outside of the blade net, so that the blade net and the blade net frame keep synchronization, the bottom of the blade net frame is connected to the positioning frame, the positioning frame is placed on the top of the blade head spring piece, and the blade head spring piece is installed in the head cover;
[0008] A clearance hole is provided at a position of the head cover corresponding to the knife net frame, the knife net frame is inserted into the clearance hole, and the clearance hole and the knife net frame are limited by the outer shape.
[0009] Furthermore, the positioning frames are not connected to each other, so that the knife net frames float independently and are not related to each other.
[0010] Furthermore, a notch is provided on the outside of the knife net, and a tenon is provided on the inside of the knife net frame, and the notch on the outside of the knife net is clamped by the tenon, so that the knife net and the knife net frame are kept synchronized.
[0011] Furthermore, a buckling foot extends out from one end of the knife net frame corresponding to the positioning frame, and a buckling hole is provided at the position of the buckling foot corresponding to the positioning frame. The buckling foot buckles in the buckling hole to connect the knife net frame and the positioning frame together.
[0012] Furthermore, a movable knife is arranged in the knife net, and a rotating component is arranged at the bottom of the movable knife. The rotating component passes through the cutter head spring piece and the positioning frame from bottom to top and is connected with the movable knife. A yielding groove is provided at the position of the positioning frame corresponding to the rotating component.
[0013] Furthermore, the rotating component includes a rotating shaft, a positioning shaft arranged below the rotating shaft, and a spring arranged between the rotating shaft and the positioning shaft. One end of the rotating shaft is arranged in the positioning shaft and can slide up and down in the positioning shaft. The other end of the rotating shaft is used to connect with the moving knife to drive the moving knife to rotate; the spring is used to push the rotating shaft to move upward.
[0014] The beneficial effects of the utility model are embodied in:
[0015] The utility model eliminates the fixed rotating shaft between the head cover and the knife net frame, connects the knife net frame with the positioning frame, and allows the knife net frame and the head cover to be limited by the shape, so that when any part of the knife net frame is pressed, this part can float.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0021] See also Figure 1-Figure 2 .
[0022] The utility model discloses a novel floating structure of a razor blade head, comprising a head cover 1, a blade net 2, a blade net frame 3, a positioning frame 4 and a blade head spring piece 5. The blade net frame 3 is clamped on the outer side of the blade net 2 so that the blade net 2 and the blade net frame 3 keep synchronization. The bottom of the blade net frame 3 is connected to the positioning frame 4, and the positioning frame 4 is placed on the top of the blade head spring piece 5. The blade head spring piece 5 is installed in the head cover 1.
[0023] A clearance hole 11 is opened at the position of the head cover 1 corresponding to the knife net frame 3. The knife net frame 3 is inserted into the clearance hole 11. The clearance hole 11 and the knife net frame 3 are limited by the shape. No fixed rotating shaft is set between the head cover 1 and the knife net frame 3.
[0024] The utility model eliminates the fixed rotating shaft between the head cover 1 and the knife net frame 3, connects the knife net frame 3 with the positioning frame 4, and allows the knife net frame 3 and the head cover 1 to be limited by the shape, so that by pressing any part of the knife net frame 3, this part can float (not only can it tilt to one side, but also can float up and down), the knife net frame 3 is not provided with a fixed rotating shaft, but can have countless rotating shafts, thus giving the knife net frame 3 a great degree of freedom, and can achieve a 360-degree surface floating effect.
[0025] In one embodiment, the positioning frames 4 are not connected to each other, so that the knife net frames 3 float independently and are not related to each other. With this design, there is no coupling structure between any two knife net frames 3, and the knife net frames 3 are only constrained by the head cover 1 and the spring. When one knife net frame 3 is pressed, the other knife net frames 3 will not rotate accordingly. When several knife net frames 3 receive pressure in different directions at the same time, each knife net frame 3 will rotate in the direction of the pressure. In this way, when the knife net frames 3 float, they can better fit different areas of the face.
[0026] In one embodiment, a notch is provided on the outside of the knife net 2, and a tenon is provided on the inside of the knife net frame 3. The notch on the outside of the knife net 2 is clamped by the tenon, so that the knife net 2 and the knife net frame 3 are kept synchronized.
[0027] In one embodiment, a buckling foot 31 extends from one end of the knife net frame 3 corresponding to the positioning frame 4, and a buckling hole 41 is provided at the position of the positioning frame 4 corresponding to the buckling foot 31. The buckling foot 31 is buckled in the buckling hole 41 to connect the knife net frame 3 and the positioning frame 4. With this design, the buckling setting not only limits the relative position of the knife net frame 3 and the positioning frame 4, but also facilitates the disassembly and assembly of the knife net frame 3 and the positioning frame 4.
[0028] In one embodiment, a movable knife 6 is provided in the knife net 2, and a rotating component 7 is provided at the bottom of the movable knife 6. The rotating component 7 passes through the cutter head spring piece 5 and the positioning frame 4 from bottom to top and is connected to the movable knife 6. A clearance groove 42 is opened at the position of the positioning frame 4 corresponding to the rotating component 7.
[0029] In a specific implementation, the rotating component 7 is used to connect with the driving shaft on the blade of the electric shaver to transmit power to the movable blade 6 to drive the movable blade 6 to rotate. The setting of the clearance groove 42 can avoid interference between the positioning frame 4 and the rotating component 7, allowing the blade head to work normally.
[0030] In one embodiment, the rotating component 7 includes a rotating shaft 71, a positioning shaft 72 arranged below the rotating shaft 71, and a spring 73 arranged between the rotating shaft 71 and the positioning shaft 72. One end of the rotating shaft 71 is arranged in the positioning shaft 72 and can slide up and down in the positioning shaft 72 (can only slide up and down relative to the positioning shaft 72, and cannot rotate relative to the positioning shaft 72), and the other end of the rotating shaft 71 is used to connect with the movable knife 6 to drive the movable knife 6 to rotate; the spring 73 is used to push the rotating shaft 71 to move upward.
[0031] In a specific implementation, the driving shaft on the blade of the electric shaver is connected to the positioning shaft 72, and then drives the rotating shaft 71 to rotate, thereby driving the movable blade 6 to rotate. In a free state, the elastic force of the spring 73 is applied to the rotating shaft 71 and then transmitted to the movable blade 6 and the blade net 2. The blade net frame 3 is only subjected to the pre-pressure transmitted by the blade head shrapnel 5. In a working state, the blade net 2 is subjected to downward pressure, and the blade net 2 begins to move downward under the action of the downward pressure. When simulating shaving, the face is subjected to the reaction force of the spring 73, and the force is relatively small at this time. When the pressure continues to be applied, the blade net 2 continues to move downward until it contacts the blade net frame 3, and the blade net 2 moves downward together with the blade net frame 3. At this time, the blade net 2 is subjected to the double reaction force of the spring 73 and the blade head shrapnel 5. At this time, the force is relatively large. In this way, two-stage independent floating is achieved, the force of the first-stage floating is relatively small, and the blade head slides more smoothly on the face; the force of the second-stage is relatively large, and the force feedback of the face is more obvious.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0035] In addition, "plurality" means two or more.
