[0037] In the embodiment, referring to Figure 2 、 5 and 6, the swing seat 200 is provided with a clamping groove 240, the lower end of the elastic reset sleeve 340 is formed with a lower turning edge 342, the lower end of the elastic reset sleeve 340 is clamped in the clamping groove 240 through the lower turning edge 342, the upper end of the elastic reset sleeve 340 is provided with an upper turning edge 341, the upper turning edge 341 is correspondingly clamped between the swing seat 200 and the inner wall of the mounting groove, and the assembly of the elastic reset sleeve 340, the floating head 300 and the swing seat 200 is realized.
[0038] In the embodiment, the upper end of the elastic reset sleeve 340 is embedded between the inner wall of the mounting groove and the inner wall of the swing sleeve 360. One advantage is that the gap between the floating head 300 and the swing sleeve 360 can be sealed, preventing dust, hair and the like from entering the floating head 300 through the gap, effectively improving the dustproof and anti-pollution effect of the floating head 300. Another advantage is that the impact force of the swing seat 200 when swinging in the matching cavity 361 can be buffered by the elastic force of the elastic reset sleeve 360 itself, thereby avoiding swing noise and running noise caused by assembly gap when the floating head swings, effectively improving the user experience.
[0039] In the embodiment, referring to Figure 2 , 5 and 6, in order to improve the stability of the installation structure between the elastic reset sleeve 340 and the swing sleeve 360, the swing sleeve 360 is provided with a limiting protrusion 364, and the upper turning edge 341 is provided with a limiting hole 3411 corresponding to the limiting protrusion 364. When the elastic reset sleeve 340 is wrapped around the upper end of the swing sleeve 360, the limiting protrusion 364 on the swing sleeve 360 is embedded in the limiting hole 3411, thereby improving the structural stability of the elastic reset sleeve 340 and the swing sleeve 360 after assembly, and preventing coaxial rotation of the two.
[0040] In the embodiment, the outer periphery of the ball head 510 is located between the swing seat 200 and the floating head 300 and is provided with a swing gap, so that the floating head 300 can swing in the swing gap with the ball head 510 as the rotation point. Compared with the existing spring 634 floating mode of the floating head 300, the swing structure stability of the floating head 300 in the horizontal direction can be improved, so that the floating head 300 can better change the swing angle to fit the human face. At the same time, since the floating head 300 is rotated with the convex head and the matching hole 230 as the swing point, the floating head 300 will not appear when it is used to shave the human skin. The floating head 300 in the vertical direction is limited to horizontal direction swing, thereby making the floating head 300 swing relatively more stable and quiet.
[0041] In the embodiment, the ball head 510 is a hemispherical structure, which is arranged at the bottom center position of the floating head 300. The corresponding matching hole 230 is a hemispherical hole, which is shaped to match the shape of the ball head 510, so that the ball head 510 can rotate in the matching hole 230.
[0042] In the embodiment, referring to Figure 2, the shape of the swing seat 200 can be a hollow cylindrical structure or other three-dimensional structure. In this embodiment, the swing seat 200 is taken as an example of a cylindrical structure, which has a cavity inside as an embodiment of the swing gap. The swing seat 200 extends from the matching hole 230 to the side direction, and the end face is vertically inclined downward to form an umbrella-shaped inclined surface at the upper end of the swing seat 200. The matching hole 230 is correspondingly arranged at the center of the upper end of the swing seat 200. At this time, the bottom of the floating cutter head 300 can be a flat surface. In this way, the swing gap formed between the inclined surface at the upper end of the swing seat 200 and the bottom of the floating cutter head 300 can make the floating cutter head 300 swing around the ball head 510 in the swing gap to make the floating cutter head 300 fit the human skin and hair. The floating cutter head 300 is relatively stable and quiet when swinging.
[0043] As another embodiment of the swing gap, this embodiment is different from the above-mentioned embodiment. In this embodiment, the upper end of the swing seat 200 can be arranged as a flat surface, and the bottom of the floating cutter head 300 can be arranged as an umbrella-shaped inclined surface. That is, the umbrella-shaped inclined surface at the upper end of the swing seat 200 in the above-mentioned embodiment is mirrored to the bottom of the floating cutter head 300. In this way, the swing gap is formed between the inclined surface at the bottom of the floating cutter head 300 and the flat surface at the upper end of the swing seat 200, and the above-mentioned effect can also be achieved.
[0044] As a third embodiment of the swing gap, the two above-mentioned embodiments can be combined. That is, the upper end of the swing seat 200 and the bottom of the floating cutter head 300 are both arranged as inclined surfaces. In this way, the swing gap is formed between the two inclined surfaces, and the normal swing effect of the floating cutter head 300 around the ball head 510 can also be achieved.
[0045] In this embodiment, the matching hole 230 is arranged at the center of the end face of the swing seat 200. The cross-sectional area of the matching hole 230 is much smaller than the area of the upper end of the swing seat 200. The area of the ball head 510 is relatively smaller than the area of the bottom of the floating cutter head 300. In this way, the smaller contact surface between the ball head 510 and the matching surface can be utilized to further reduce the contact friction between the floating cutter head 300 and the swing seat 200 when the floating cutter head 300 swings relative to the swing seat 200. As a result, the frictional resistance of the floating cutter head 300 when swinging is smaller, and the noise generated when swinging is also smaller.
[0046] In this embodiment, the diameter of the ball head 510 is preferably within 3mm-10mm. This diameter setting can ensure the structural stability of the hinge between the floating cutter head 300 and the swing seat 200, and also maximizes the reduction of the contact surface between the ball head 510 and the matching hole 230. As a result, the contact friction between the floating cutter head 300 and the swing seat 200 is reduced, and point contact instead of large-area surface contact is formed between them. This can reduce the frictional wear and noise of the corresponding components, improve the service life of the product, and improve the smoothness of the floating cutter head 300 when swinging.
[0047] It is conceivable that, as long as the ball head 510 and the corresponding material structure strength of the matching hole 230 are guaranteed, the diameter of the ball head 510 and the area of the corresponding matching hole 230 are as small as possible, which can reduce the wear and make the floating cutter head 300 swing more easily to reduce noise. Due to different material strengths, the diameter of the ball head 510 may be less than 3 mm or greater than 10 mm under the above-mentioned inspiration, which is not listed in detail here.
[0048] In this embodiment, referring to Figure 2 (C represents the swing gap), the angle of the swing gap is preferably within 5°-15°. The swing angle, i.e. the optimal swing angle between the floating cutter head 300 and the swing seat 200, enables the floating cutter head 300 to better fit the human skin when rotating, while also avoiding the problem of affecting normal use due to too small or too large swing angle of the floating cutter head 300. The angle setting is more in line with the swing angle of the shaver when trimming hair. It is conceivable that the swing angle of the swing gap may also be outside the above-mentioned angle numbers, based on the inspiration that a corresponding umbrella-shaped structure swing gap is formed between the outer side of the ball head 510 and the end face between the floating cutter head 300 and the swing seat 200. Other setting angles are within the protection scope of this embodiment, and preferably the swing gap angle is preferably 10°. This angle more meets the angle requirement of the floating cutter head 300 when swinging to fit the human skin, while also ensuring the structural stability between the floating cutter head 300 and the swing seat 200.
[0049] Based on the above embodiment, referring to Figure 2 and 3 , in order to further optimize the maintenance cost of each component of the product and optimize the structure stress point between the floating cutter head 300 and the swing seat 200, a swing frame 500 is arranged at the bottom of the floating cutter head 300. The swing frame 500 can be screwed at the bottom of the floating cutter head 300, and the ball head 510 is arranged at the bottom of the swing frame 500. The ball head 510 can be integrally formed with the swing frame 500. In this way, by using the above structure, the connection stress point between the swing seat 200 and the floating cutter head 300 can be transferred to the swing frame 500, thereby improving the structural strength of the floating cutter head 300. When the ball head 510 is worn and smooth, a new ball head 510 can be replaced by replacing the swing frame 500 without replacing the entire shell structure of the floating cutter head 300, effectively reducing the product maintenance cost.
[0050] Based on the above embodiments, in order to further reduce the contact friction between the floating cutter head 300 and the rocker seat 200 during swinging, so as to make the floating cutter head 300 swing more smoothly, an oil reservoir 511 is provided between the surface of the ball head 510 and the mating hole 230. The lubricating oil stored in the oil reservoir 511 can reduce the contact friction between the ball head 510 and the inner wall of the mating hole 230.
[0051] Specifically, as one embodiment of the oil storage tank 511, refer to Figure 3 and 4 The oil reservoir 511 can be opened on the ball head 510 and is set along the weft line of the ball head 510. When the ball head 510 swings on the inner wall of the mating hole 230, the lubricating oil in the oil reservoir 511 can reduce the contact friction between the ball head 510 and the mating hole 230, making the entire floating cutter head 300 swing more smoothly and stably.
[0052] As another embodiment of the oil outlet groove, the oil storage groove 511 can also be a groove formed on the inner wall of the mating hole 230, which can also achieve the above-mentioned lubrication effect. Of course, it is also possible to provide oil storage grooves 511 on both the surface of the ball head 510 and the inner wall of the mating hole 230.
[0053] In this embodiment, the lubricating oil is preferably a solid flexible lubricating oil, such as grease, which has good lubrication effect and strong adhesion, and will not cause lubricating oil leakage due to misalignment and exposure between the oil reservoir 511 and the inner wall of the mating hole 230.
[0054] In this embodiment, the swing sleeve 360 is preferably detachably connected to the floating cutter head 300 to facilitate the assembly of the swing sleeve 360, the swing seat 200 and the floating cutter head 300.
[0055] In this embodiment, the rocker sleeve 360 and the gear compartment 310 are firmly fixed by screws. The corresponding screw connection between the rocker frame 500 and the floating cutter head 300 can also be achieved using the same screws. In this way, by having the screws on the rocker sleeve 360 pass through the rocker frame 500 and lock it onto the floating cutter head 300, the installation of the rocker seat 200, the rocker frame 500, and the rocker sleeve 360 can be completed without involving other redundant assembly parts. This effectively reduces the unnecessary assembly gaps between components caused by the traditional rocker seat 200 using snap-fit or other fixing methods, which can lead to abnormal rocking noise and complicated product assembly.
[0056] In this embodiment, refer to Figure 3 The upper end face of the swing frame 500 is provided with several positioning posts 513, and the bottom of the corresponding floating cutter head 300 is provided with corresponding positioning holes that cooperate with the positioning posts 513. In this way, by inserting the positioning posts 513 into the positioning holes, the pre-assembly work between the two can be easily completed, so that the two can be screwed together and tightened later.
[0057] In this embodiment, with reference to Figure 2 and 5 , the shape of the fitting cavity 361 is similar to a circular truncated cone shape or a funnel shape, and the side surface is arc-shaped. The upper end of the swing sleeve 360 is also provided with a corresponding circular truncated cone shape. When the swing sleeve 360 and the swing seat 200 are combined, the lower end of the swing seat 200 can be first inserted into the fitting cavity 361, and then the upper end of the swing seat 200 is connected to the fitting cavity 361 to form a swing fit, realizing the connection of the two. At this time, after the swing sleeve 360 and the floating tool head 300 are installed, the fitting hole 230 at the upper end of the swing seat 200 is correspondingly connected to the ball head 510 to form a rotating fit.
[0058] Further, with reference to Figure 5 , in order to prevent the swing seat 200 from rotating in the axial direction in the fitting cavity 361, and to limit the movement direction of the swing seat 200 to the horizontal plane, a rotation stopping groove 362 is arranged on the inner wall of the fitting cavity 361. The upper end of the swing seat 200 is provided with a rotation stopping rib 220 that cooperates with the rotation stopping groove 362. The rotation stopping rib 220 and the rotation stopping groove 362 are in sliding cooperation, and the movement range of the swing seat 200 is limited.
[0059] Further, in order to reduce the friction of the swing seat 200 when it swings horizontally in the fitting cavity 361, and to make the swing seat 200 swing more smoothly in the swing sleeve 360, a convex part 363 or a recessed part is arranged on the inner wall of the fitting cavity 361. With reference to Figure 5 , taking the convex part 363 as an example, the convex part 363 is arranged along the height direction of the inner wall of the fitting cavity 361. When the swing sleeve 360 is movably embedded in the fitting cavity 361, the outer side of the swing sleeve 360 is in contact with the convex part 363. Due to the existence of the convex part 363, the contact surface between the swing sleeve 360 and the fitting cavity 361 can be limited to the convex part 363, thereby reducing the contact surface between the swing seat 200 and the swing sleeve 360, and achieving the effect of reducing wear and noise.
[0060] In this embodiment, the recessed part has the same principle as the convex part 363, which aims to reduce the contact friction surface between the swing seat 200 and the swing sleeve 360, and achieve the effect of reducing wear and noise. Therefore, it will not be described in detail here.
[0061] Based on the above embodiment, with reference to Figure 2 and 4In the embodiment, the elastic reset sleeve 340 can be arranged between the swing seat 200 and the floating cutter head 300, and then the elastic reset sleeve 340 is used to elastically reset and support the floating cutter head 300 after swinging. The elastic reset sleeve 340 can be arranged outside the swing sleeve 360, and the upper end and the lower end of the elastic reset sleeve 340 are respectively in abutment with the floating cutter head 300 and the swing sleeve 360. The elastic reset sleeve 340 can be an elastic rubber sleeve, a spring 634, a compression spring or other elastic components.
[0062] Based on the above embodiments, referring to Figure 6 and 7 , a shaving razor is provided, which includes a body 100, a circular cutter head 331, a transmission assembly and a rotary actuator. The floating cutter head 300 includes a gear compartment 310, a gear compartment cover 320 and a cutter head shell 330. The circular cutter head 331 is arranged in the cutter head shell 330. The rotary actuator is arranged in the body 100. The floating cutter head 300 is detachably mounted on the body 100 through the swing sleeve 360. The transmission mechanism includes a transmission shaft 600. The upper end of the transmission shaft 600 penetrates the ball head 510 and is linked with the circular cutter head 331. The lower end of the transmission shaft 600 is linked with the rotary actuator.
[0063] In the embodiment, the cutter head shell 330 can be clamped on the gear compartment cover 320. Alternatively, the two can be hingedly connected on one side and magnetically attracted on the other side through a magnetic attraction member, so as to realize the flip opening of the two, thereby facilitating the cleaning of the gear compartment cover 320 and the circular cutter head 331.
[0064] In the embodiment, the rotary actuator can be a motor, an electric motor 700 or other actuators capable of outputting rotary power.
[0065] In the embodiment, the body 100 is provided with a jack 120 matched with the swing seat 200. The inner wall of the jack 120 is provided with a snap spring 110, and the side of the corresponding swing seat is provided with a bayonet 210. When the swing seat 200 is inserted into the jack 120, the snap spring 110 is correspondingly clamped on the bayonet 210, thereby completing the relative locking between the lower end of the swing seat 200 and the body 100.
[0066] In the embodiment, for the shaving razor designed with multiple circular cutter heads 331, generally, there are multiple circular cutter heads 331. Taking three circular cutter heads 331 as an example, the three circular cutter heads 331 are generally arranged in a triangular shape. When the transmission shaft 600 and the multiple circular cutter heads 331 are in transmission and the transmission shaft 600 and the electric motor are in transmission, corresponding gear assemblies are arranged, so as to realize the power transmission between the electric motor and the transmission shaft 600 and the power transmission between the transmission shaft 600 and the multiple circular cutter heads 331 through the gear assemblies.
[0067] In the embodiment, the transmission shaft 600 comprises an input shaft 610, an elastic coupling 630 and an output shaft 620, one end of the input shaft 610 is rotatably connected in the body 100 and is linked with the output shaft 620 of the motor through a gear assembly, the other end of the output shaft 620 is elastically connected with the lower end of the output shaft 620 through the elastic coupling 630, and the upper end of the output shaft 620 is correspondingly linked with the plurality of circular cutter heads 331 through the gear assembly to form a power transmission.
[0068] Specifically, the gear assembly comprises a second gear set 420 for power transmission between the plurality of circular cutter heads 331 and the transmission shaft 600, and a first gear set 410 for transmission between the transmission shaft 600 and the motor, the first gear set 410 comprises a first gear 411 arranged on the output shaft 620 of the motor, one side of the first gear 411 is engaged with a second gear 412, the second gear 412 is sleeved on the outside of the input shaft 610 to drive the input shaft 610 to rotate, the second gear set 420 is arranged inside the gear compartment 310 and is limited inside the gear compartment 310 by the gear compartment cover 320, the second gear 412 comprises a central gear 421 and a planetary gear 422 arranged around the central gear 421, the planetary gear 422 is rotatably connected with the gear compartment 310, the upper end of the center of the planetary gear 422 is connected with the circular cutter head 331 through an elastic joint, and the center of the central gear 421 is connected with the upper end of the output shaft 620. Thus, the operation principle of the whole shaver is that the motor is started to drive the first gear 411 to rotate, the first gear 411 engages the second gear 412 to rotate to drive the input shaft 610 to rotate in the body 100 through the second gear 412, the input shaft 610 is driven to rotate the output shaft 620 through the elastic coupling 630, and then the central gear 421 is driven to rotate, the central gear 421 engages the planetary gear 422 to drive the circular cutter head 331 to rotate on the cutter head cover to realize trimming of the hair.
[0069] In the embodiment, the planetary gear 422 is rotatably connected with the gear compartment 310, when the planetary gear 422 is stressed, the force is transferred to the gear compartment 310, the stability and force bearing capacity of the planetary gear 422 are better, and the structural strength is relatively better.
[0070] Based on the above embodiment, the ball head 510 is arranged at the bottom center of the gear bin 310, and the matching hole 230 is arranged at the upper end of the swing seat 200. Of course, the matching hole 230 can also be arranged at the bottom of the floating cutter head 300, and the ball head 510 is arranged at the bottom of the swing seat 200. Preferably, the ball head 510 is arranged at the bottom of the floating cutter head 300, and the matching groove is arranged at the upper center of the swing seat 200. The advantage of this design is that in order to pass the output shaft 620 through the ball head 510, the center gear 421 is left above the swing frame 500, and the center gear 421 does not have an assembly relationship with the gear bin cover 320 plate. Therefore, the gear bin cover 320 only plays a role of the cover plate 332 and does not participate in the movement assembly of the gear. In this way, the number of parts participating in the transmission assembly is reduced, the assembly accuracy is increased, and the noise of the movement of the gear bin 310 is reduced.
[0071] In the embodiment, referring to Figure 7 , the elastic coupling 630 includes a transmission seat 632, a spring 634, a floating connecting head 631 and a transmission connecting head 633. The transmission seat 632 is arranged at the upper end of the input shaft 610. The transmission seat 632 is elastically connected with the floating connecting head 631 through the spring 634. The floating connecting head 631 can swing relative to the transmission seat 632 in the horizontal plane through the spring 634. The transmission connecting head 633 is arranged at the lower end of the output shaft 620 and has a plug hole inside. The floating connecting head 631 can be inserted into the plug hole to be coaxially connected and rotated with the transmission connecting head 633. In this way, the input shaft 610 and the output shaft 620 can still maintain the transmission of power torque after being relatively bent or elastically floated through the elastic coupling 630.
[0072] In the embodiment, the elastic joint between the planetary gear 422 and the circular cutter head 331 is similar in structure to the elastic coupling 630 and is designed according to the elastic joint commonly used in existing razors. Therefore, no detailed description is given here.
[0073] In the embodiment, referring to Figure 6 and 7 , the center of the center gear 421 is provided with a convex column 4211. The inside of the convex column 4211 is hollow. The upper end of the output shaft 620 is embedded into the convex column 4211 to be connected with the center gear 421. In this way, the center gear 421 does not have an assembly relationship with the gear bin cover 320 plate. Therefore, the gear bin cover 320 plate only plays a role of the cover plate 332 and does not participate in the movement assembly of the center gear 421. In this way, the number of parts participating in the transmission assembly is reduced, the assembly accuracy is increased, and the noise of the movement of the gear bin 310 is reduced.
[0074] In the embodiment, the lower end portion of the output shaft 620, the elastic coupling 630 and the upper end portion of the input shaft 610 are all arranged inside the hollow of the swing base 200, and when the whole floating tool head 300 swings through the ball head 510, the transmission connecting head 633 swings through the spring 634 on the floating connecting head 631 to bend on the transmission seat 632, so the elastic swing point of the whole elastic coupling 630 falls on the floating connecting head 631 and the transmission seat 632, so that only one transmission connecting head 633 needs to be arranged at the lower end of the output shaft 620, and the sum of the length of the transmission connecting head 633 and the length of the output shaft 620 inside the swing base 200 can be very short, which has the advantage that when the floating tool head 300 swings, the transmission connecting head 633 at the lower end of the output shaft 620 is not easy to touch the inner wall of the hollow of the swing base 200, thereby ensuring that the floating tool head 300 can normally swing, and correspondingly, the diameter of the swing base 200 does not need to be set too thick, so that the normal swing of the floating tool head 300 can be met, and the size of the swing base 200 is not too large to affect the arrangement of other components.

Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
