Description

Technical Field

[0001] This application relates to the field of consumer goods, and in particular to a razor. Background Technology

[0002] In modern life, razors have become an essential daily item for every man. Traditional blade razors require skilled techniques and are prone to causing cuts and nicks. Compared to traditional blade razors, electric razors can better conform to the contours of the face, resulting in a cleaner, smoother shave. These razors not only reduce the risk of cuts but also make it easier to reach even the smallest details on the face.

[0003] Related prior art, such as Chinese patent application "An Electric Shaver Head", application number: CN202122641651.7, discloses a shaving head including a circular blade holder, a mesh cover detachably connected to the circular blade holder, a blade assembly for rotary cutting rotatably connected between the mesh cover and the circular blade holder, and the mesh cover and the circular blade holder confine the blade assembly between them so that it cannot be separated, and a shaving head shell is provided outside the circular blade holder, and the circular blade holder is rotatably connected to the side wall of the shaving head shell.

[0004] For example, Chinese patent application "A Rotary Electric Shaver", application number: CN201720329212.3, discloses a shaver including a housing, a top cover, a blade assembly, and a rotating shaft. The blade assembly is located in the top cover. The shaver assembly, from top to bottom, includes a cutting element, a hair-pulling element, and a flat plate support. The front of the flat plate support has a cylindrical boss, on which the cutting element and the hair-pulling element are fitted. The back of the flat plate support has a concave connecting end, which has a downward-facing regular polygonal interface with at least five sides. The rotating shaft is rotatably connected to the upper part of the housing, and the upper end of the rotating shaft has a connector that matches the regular polygonal interface of the concave connecting end.

[0005] In existing shaver designs, only the top surface of the shaver head comes into contact with the skin. The actual effective shaving area is concentrated only on the surface where the shaver head is located, resulting in a limited effective shaving area and low shaving efficiency for the user. Furthermore, there is room for improvement in the functionality of existing shavers to enhance user comfort. Summary of the Invention

[0006] The technical problem to be solved by this application is to provide a shaver that uses a rotating head to significantly increase the shaving area and improve shaving efficiency; and to optimize the structural design of the shaver's working surface to improve user comfort.

[0007] The technical solution adopted in this application is as follows: a shaver, including a head, a middle seat, and a body, wherein a control circuit board and a drive motor are installed inside the body, the head is mounted on the middle seat, and the middle seat is rotatably connected to the body, and a blade assembly and an electrode assembly are arranged on the contact surface of the head that contacts human skin; the control circuit board includes an ion generator circuit, which is electrically connected to the electrode assembly, and the control circuit board controls the electrode assembly to generate ions, and the drive motor drives the middle seat to rotate, thereby driving the blade assembly to work, and the rotation of the middle seat drives the head to rotate.

[0008] Compared to existing technologies, the advantages of this application lie in the addition of a central seat, which is rotatably connected to the body. A drive motor rotates the central seat. The shaving head is then mounted on the central seat, isolating it from the body. The rotation of the central seat drives the rotation of the shaving head, eliminating relative rotation between the shaving head and the central seat, thus improving the shaving head's stability. Compared to the connection between the shaving head and the body, the connection between the central seat and the body has a significantly larger contact area, resulting in more stable rotation of the central seat within the body. This application, by adding a rotating central seat, enables the entire shaving head, containing the blade assembly, to rotate. This transforms the effective shaving area from the original contact surface containing the blade assembly to a circular surface formed by the blade assembly rotating around the central axis of the shaving head. During shaving, the effective working area is significantly increased, greatly improving shaving efficiency.

[0009] An electrode assembly is installed on the shaving head, and an ion generator circuit is added inside the body. The ion generator circuit is electrically connected to the electrode assembly, so when the ion generator circuit is active, ions are released through the electrode assembly. Since the electrode assembly is positioned on the contact surface with human skin, the ions released by the electrode assembly can fully contact the user's facial skin. This contact between the generated ions and the user's facial skin helps alleviate discomfort such as dryness and heat during shaving, resulting in a better user experience.

[0010] The ion generator circuit involved in this application is prior art and can be directly obtained through procurement. This application directly applies the ion generator circuit and does not involve any related improvements to the ion generator circuit; therefore, these will not be elaborated upon in this application.

[0011] In some embodiments of this application, the drive motor outputs power through a connected transmission shaft, which passes through the middle seat and extends to the machine head. The middle seat is connected to the transmission shaft through a first transmission assembly, and the cutter head assembly is connected to the transmission shaft through a second transmission assembly.

[0012] In some embodiments of this application, the drive shaft is a gear shaft.

[0013] In some embodiments of this application, the first transmission assembly is installed inside the middle seat. The first transmission assembly includes at least one first gear. The middle seat is a disc structure adapted to the fuselage. Gear teeth are arranged on the inner wall of the middle seat. The first gear transmits the rotation of the gear shaft to the middle seat.

[0014] Preferably, the first transmission component includes three first gears, which are evenly distributed in three directions of the gear shaft. The first gears mesh with the gear shaft, and the first gear shaft meshes with the inner wall surface of the middle seat.

[0015] In some embodiments of this application, the second transmission assembly is installed inside the machine head, and the second transmission assembly includes a second gear that corresponds one-to-one with the number of cutter head assemblies.

[0016] Specifically, common shavers on the market include two-blade shavers, three-blade shavers, and four-blade shavers. Correspondingly, the second transmission component can have two, three, or four second gears. Each second gear corresponds to a shaver head assembly, and the rotation of the second gear drives the shaver head assembly to work.

[0017] In some embodiments of this application, the central shaft of the second gear is connected to the cutter head assembly, the second gear meshes with the gear shaft, and the rotation of the gear shaft drives the second gear to rotate.

[0018] Thus, this application achieves the rotation of the center seat and the entire cutter head, as well as the operation of each cutter head assembly, using a single drive motor. Furthermore, the rotational speed of the cutter head and the rotational speed of the blades within the cutter head assembly can be controlled by selecting the first gear and the second gear.

[0019] In some embodiments of this application, the top of the fuselage is configured as a disc structure adapted to the middle seat structure, and the middle seat rotates on the top surface of the fuselage.

[0020] From an aesthetic perspective, the center seat can be designed as an integral part of the body, which would improve the overall appearance of this application. Considering ease of transmission, this application designs the center seat as a disc structure, and correspondingly, the top of the body is also designed as a disc structure to avoid making the center seat appear obtrusive. Other parts of the body do not have specific requirements and can be designed primarily based on user comfort.

[0021] In some embodiments of this application, a base plate is disposed inside the machine head, the cutter head assembly is mounted on top of the base plate, and the second gear is mounted below the base plate. The central shaft portion of the second gear passes through the base plate and connects to the cutter head assembly. This application uses a base plate to mount the cutter head assembly and the second gear, resulting in better stability and reduced wobbling after installation.

[0022] In this application, an electrode assembly is added to release ions. Therefore, with the addition of other functions, the shaver also needs an internal ion generator circuit, which in turn needs to be electrically connected to the electrode assembly. The control circuit board containing the ion generator circuit is installed inside the shaver body. Therefore, during wiring, one end of the conductive wire needs to be connected to the control circuit board, and the other end needs to pass through the rotating center seat to reach the shaver head and connect to the electrode assembly.

[0023] The central seat itself rotates, and inside it are a rotating drive shaft and a first gear; the machine head itself does not rotate, but inside it are a drive shaft and a second gear. So how to pass through the rotating central seat and avoid the drive shaft, the first gear, and the second gear is another important concept of this application.

[0024] In some embodiments of this application, the drive motor and the transmission shaft are both made of conductive metal material. The ion generator circuit is connected to the drive motor through conductive lines. The drive motor transmits electrical signals to the transmission shaft, and the transmission shaft is connected to the electrode assembly through conductive lines.

[0025] This completes the electrical connection between the ion generator circuit and the electrode assembly. The wiring is only located inside the body and head of the shaver, eliminating the need for conductive wires to pass through the central support. This minimal wiring simplifies the internal circuitry of the shaver and avoids the potential for interference between conductive wires and the drive shaft or transmission components, which would occur if the conductive wires ran from the body to the head.

[0026] In some embodiments of this application, the conductive wire located inside the machine head can be configured to be fixed inside the machine head, with one end of the conductive wire in contact with the drive shaft and the other end in contact with the electrode assembly. Because both the drive shaft and the electrode assembly are rotating structures, the conductive wire is designed to be in contact but not fixed.

[0027] In some embodiments of this application, a base plate is disposed inside the machine head, and a bearing is mounted on the base plate. The bearing is made of a conductive metal material, and the drive shaft passes through the base plate and is connected to the bearing. The outer surface of the bearing is connected to the electrode assembly via conductive wires. This completes the circuit layout in this application.

[0028] On the one hand, by passing the top of the drive shaft through the substrate and connecting it to the bearing fixed on the substrate, the structure of the drive shaft can be made more stable and the rotation smoother. On the other hand, the drive shaft transmits electrical signals to the bearing, which is mounted on the substrate and whose outer wheel is fixed. Therefore, compared to the drive shaft, the present application provides a simpler and more reliable solution by connecting the bearing and the electrode assembly through a conductive wire.

[0029] In some embodiments of this application, the electrode assembly includes at least two electrodes. Two electrodes are sufficient to release ions, although multiple electrodes may also be used.

[0030] The electrode is a ball bearing structure, a cylindrical structure, or a strip structure.

[0031] In some embodiments of this application, the electrode is a ball bearing structure, and the electrode is movably connected to the head housing, and the electrode can rotate under force.

[0032] In this embodiment, the electrode adopts a ball bearing structure and a movable connection method, which allows the electrode to rotate along the direction of force when in contact with human skin. Firstly, the contact between the user and the ball bearing is smooth and comfortable; secondly, the electrode also plays a massage role.

[0033] In some embodiments of this application, the electrode is a cylindrical structure, the electrode is movably connected to the head housing, and the electrode can rotate around an axis under force.

[0034] In this embodiment, the electrode adopts a cylindrical structure. Similarly, when the electrode comes into contact with human skin, it can rotate under force, which provides a more comfortable user experience and also serves as a massage function.

[0035] To further enhance the massage effect of this application, a small vibrator can be added inside the head or body. The vibrator transmits vibrations to the electrode components, enabling the electrode components to simultaneously perform vibration massage.

[0036] In some embodiments of this application, the shaver head is provided with three blade assembly, and the electrode is arranged between two adjacent blade assembly. The electrode is a smooth, elongated structure. This is the preferred embodiment of this application, where the blade assembly and electrode of the shaver are rationally arranged and the structure is compact.

[0037] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0045] The present application will now be described in detail with reference to the accompanying drawings.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] A razor, as described in Embodiment 1 Figure 1 , Figure 2 As shown, the device includes a shaving head 1, a middle base 2, and a body 3. A control circuit board 12 and a drive motor 4 are installed inside the body 3. The shaving head 1 is mounted on the middle base 2, which is rotatably connected to the body 3. A blade assembly 5 and an electrode assembly 11 are arranged on the contact surface 1a of the shaving head 1 where it contacts the skin. The control circuit board 12 includes an ion generator circuit, which is electrically connected to the electrode assembly 11. The control circuit board 12 controls the electrode assembly 11 to generate ions. Since the electrode assembly 11 is positioned on the contact surface 1a where it contacts the skin, the ions released by the electrode assembly 11 can fully contact the user's facial skin. This contact between the generated ions and the user's facial skin helps alleviate discomfort such as dryness and heat during shaving, resulting in a better user experience.

[0048] The drive motor 4 rotates the middle seat 2, which in turn drives the moving blade assembly 5. The rotation of the middle seat 2, in turn, rotates the shaving head 1. Since the rotation of the middle seat 2 drives the rotation of the shaving head 1, there is no relative rotation between the shaving head 1 and the middle seat 2, resulting in better stability for the shaving head 1. Compared to the connection between the shaving head 1 and the body 3, the connection between the middle seat 2 and the body 3 has a larger contact area, thus making the rotation of the middle seat 2 on the body 3 more stable. This application, by adding a rotating middle seat 2, enables the entire shaving head 1, which houses the blade assembly 5, to rotate. This transforms the effective shaving area from the original contact surface 1a where the blade assembly 5 is located into an annular surface formed by the blade assembly 5 rotating around the central axis of the shaving head 1. During shaving, the effective working area is significantly increased, greatly improving shaving efficiency.

[0049] The ion generator circuit involved in this application is prior art and can be directly obtained through procurement. This application directly applies the ion generator circuit and does not involve any related improvements to the ion generator circuit; therefore, these will not be elaborated upon in this application.

[0050] Example 2, as Figures 2 to 4 As shown, the drive motor 4 outputs power through a connected transmission shaft. The transmission shaft passes through the middle seat 2 and extends to the machine head 1. The middle seat 2 is connected to the transmission shaft through a first transmission assembly, and the cutter head assembly 5 is connected to the transmission shaft through a second transmission assembly. The transmission shaft is a gear shaft 6.

[0051] The first transmission assembly is installed inside the middle seat 2. The first transmission assembly includes at least one first gear 7. The middle seat 2 is a disc structure adapted to the body 3. Gear teeth are arranged on the inner wall of the middle seat 2. The first gear 7 transmits the rotation of the gear shaft 6 to the middle seat 2. Preferably, the first transmission assembly includes three first gears 7, which are evenly distributed in three directions of the gear shaft 6. The first gears 7 mesh with the gear shaft 6, and the first gear shaft 6 meshes with the inner wall of the middle seat 2.

[0052] The second transmission assembly is installed inside the shaver head 1. The second transmission assembly includes second gears 8 that correspond one-to-one with the number of shaver head assemblies 5. Specifically, common shavers on the market include two-blade shavers, three-blade shavers, and four-blade shavers. Correspondingly, the second transmission assembly can have two, three, or four second gears 8. Each second gear 8 corresponds one-to-one with a shaver head assembly 5, and the rotation of the second gears 8 drives the shaver head assemblies 5 to operate.

[0053] The central shaft of the second gear 8 is connected to the cutter head assembly 5, and the second gear 8 meshes with the gear shaft 6. Rotation of the gear shaft 6 drives the second gear 8 to rotate. Thus, this application achieves the rotation of the central support 2 and the entire cutter head, as well as the operation of each cutter head assembly 5 within the cutter head, all through a single drive motor 4. Furthermore, the rotational speed of the cutter head and the rotational speed of the blades within the cutter head assembly 5 can be achieved by selecting the first gear 7 and the second gear 8.

[0054] The top of the body 3 is configured as a disc structure adapted to the structure of the middle seat 2, which rotates on the top surface of the body 3. From an aesthetic perspective, the middle seat 2 can be designed as an integral part of the body 3, which would improve the overall appearance of this application. Considering the convenience of transmission, this application designs the middle seat 2 as a disc structure, and correspondingly, the top of the body 3 is also designed as a disc structure to avoid making the middle seat 2 appear obtrusive. Other parts of the body 3 do not have specific requirements and can be designed primarily based on user comfort.

[0055] The machine head 1 has a base plate 9 inside, the cutter head assembly 5 is mounted on the base plate 9, and the second gear 8 is mounted below the base plate 9. The central shaft of the second gear 8 passes through the base plate 9 and is connected to the cutter head assembly 5. This application uses a base plate 9 to mount the cutter head assembly 5 and the second gear 8, which improves the stability of the structure after installation and makes it less prone to shaking.

[0056] The rest of the contents of Example 2 are the same as those of Example 1.

[0057] Example 3, as Figures 2 to 4 As shown, the drive motor 4 and the transmission shaft are both made of conductive metal. The ion generator circuit is connected to the drive motor 4 via conductive wire 14. The drive motor 4 transmits electrical signals to the transmission shaft, which is connected to the electrode assembly 11 via conductive wire 14. This completes the electrical connection between the ion generator circuit and the electrode assembly 11. This wiring is only installed inside the body 3 and the head 1, and the conductive wire 14 does not need to pass through the middle base 2. The absence of redundant wiring simplifies the internal wiring of the shaver. It also avoids the potential for interference between the conductive wire 14 and the transmission shaft and transmission components if the conductive wire 14 passes from the body 3 to the head 1.

[0058] The conductive wire 14 located inside the machine head 1 can be configured to be fixed inside the machine head 1. One end of the conductive wire 14 is in contact with the drive shaft, and the other end of the conductive wire 14 is in contact with the electrode assembly 11. Because both the drive shaft and the electrode assembly 11 are rotating structures, the conductive wire 14 is designed to be in contact but not fixed.

[0059] The machine head 1 contains a base plate 9, on which a bearing 13 is mounted. The bearing 13 is made of conductive metal material, and the drive shaft passes through the base plate 9 and connects to the bearing 13. The outer surface of the bearing 13 is connected to the electrode assembly 11 via a conductive wire 14. This completes the circuit layout described in this application. On one hand, connecting the top of the drive shaft through the base plate 9 and to the bearing 13 fixed on the base plate 9 makes the drive shaft structure more stable and its rotation smoother. On the other hand, the drive shaft transmits electrical signals to the bearing 13, which is mounted on the base plate 9. Since the outer wheel of the bearing 13 is fixed, connecting the bearing 13 to the electrode assembly 11 via a conductive wire 14 is a simpler and more reliable solution compared to using a drive shaft.

[0060] The electrode assembly 11 includes at least two electrodes 11. Two electrodes 11 are sufficient to release ions, although multiple electrodes 11 can also be used. The electrodes 11 can be ball-bearing, cylindrical, or elongated.

[0061] The specific solution is as follows: The electrode component 11 has a ball bearing structure and is movably connected to the housing of the head 1. The electrode component 11 can rotate under force. In this solution, the electrode component 11 adopts a ball bearing structure and a movable connection method, which allows the electrode component 11 to rotate along the direction of force when in contact with human skin. Firstly, the contact between the user and the ball bearing is smooth and comfortable; secondly, the electrode component 11 also plays a massage role.

[0062] The electrode 11 has a cylindrical structure and is movably connected to the housing of the head 1. The electrode 11 can rotate around its axis under force. Similarly, in this design, the cylindrical structure of the electrode 11 allows it to rotate when in contact with human skin, providing a comfortable user experience and achieving the same massage effect. To further enhance the massage efficacy, a small vibrator can be added inside the head 1 or body 3. The vibrator transmits vibrations to the electrode 11, enabling it to simultaneously perform a vibration massage function.

[0063] The shaver head 1 is provided with three blade assembly 5, and the electrode 11 is arranged between two adjacent blade assembly 5. The electrode 11 is a smooth, elongated structure. This solution is the preferred solution of this application, and the blade assembly 5 and the electrode 11 of the shaver are reasonably arranged and have a compact structure.

[0064] The other contents of Example 3 are the same as those of Example 1 or Example 2.

[0065] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
