[0037] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0038] This utility model discloses a razor, including a blade assembly 1. Please refer to [link / reference]. Figures 1 to 6 It also includes:

[0039] The handle 2 has an opening at one end to form a receiving cavity and is detachably connected to one end of the cutter head assembly 1. The other end has a first mounting port 21 that communicates with the receiving cavity, and the side wall of the handle 2 also has a second mounting port 22 that communicates with the receiving cavity.

[0040] The charging port 3 has one end adapted to and installed in the first mounting port 21, and the other end extends into the receiving cavity;

[0041] Control switch 4, one end of which is adapted to and installed in the second mounting port 22, and the other end extends into the receiving cavity;

[0042] The control assembly includes a charging circuit board 31 and a main board 41, both installed in the receiving cavity and connected in communication. The charging circuit board 31 is electrically connected to the other end of the charging port 3, and the main board 41 is electrically connected to the other end of the control switch 4.

[0043] The first sealing member 5 covers the charging port 3, with one end abutting the inside of the handle 2 and the other end abutting the charging circuit board 31.

[0044] And a second seal 6, which covers the control switch 4, with one end abutting the inside of the handle 2 and the other end abutting the main board 41.

[0045] The control assembly is divided into a charging circuit board 31 and a main board 41, both of which are housed within a sealed cavity. The charging port 3 is located at the first mounting port 21 of the handle 2 for charging, and the first mounting port 21 is relatively sealed off via the charging port 3. Simultaneously, a control switch 4 is located at the second mounting port 22 of the handle 2 to control the start and stop of the shaver. The second mounting port 22 is also relatively sealed off via the control switch 4. This division of the control assembly mitigates the risk of water leakage in stages. Even if leakage occurs, it will only affect the charging port 3 at the first mounting port 21 and the control switch 4 at the second mounting port 22, without affecting the charging circuit board 31 and the main board 41 within the cavity. This prevents short circuits and poor contact. Only the charging port 3 and control switch 4 need to be replaced; there is no need to repair or replace the charging circuit board 31 and mainboard 41, saving maintenance costs. Furthermore, a first sealing element 5 is specially designed for the charging port 3 at the first mounting port 21 to further reduce the risk of water leakage at the first mounting port 21, and a second sealing element 6 is specially designed for the control switch 4 at the second mounting port 22 to further reduce the risk of water leakage at the second mounting port 22. This forms a two-stage seal, improving the problem of external water entering existing shavers during cleaning and damaging the control mainboard, electrical components, and other parts inside the handle, resulting in poor market competitiveness. Moreover, the above-mentioned charging waterproof structure is simple and easy to assemble. When applied to shavers or other personal care products, it improves the overall waterproof rating of the product, reduces maintenance costs, increases cost-effectiveness, and enhances the product's market competitiveness.

[0046] The charging port 3 can be fixed to the inner wall of the first mounting port 21 with sealant, and the control switch 4 can be fixed to the inner wall of the second mounting port 22 with sealant, forming the first sealing structure of the shaver to prevent water from entering the handle 2. Simultaneously, both the first seal 5 and the second seal 6 can be made of TPE / TPU / rubber, etc. The first seal 5 covers the charging port 3, with one end abutting the inner side of the handle 2 and the other end abutting the charging circuit board 31, forming the second sealing structure at the first mounting port 21 to prevent further water seepage; similarly, the second seal 6 covers the control switch 4, with one end abutting the inner side of the handle 2 and the other end abutting the main board 41, forming the second sealing structure at the second mounting port 22 to prevent further water seepage.

[0047] Charging port 3 is preferably a Type-C interface. The Type-C interface is a symmetrical interface, eliminating the need to consider alignment during insertion and solving the problem of inaccurate USB insertion. It allows for blind insertion, which is especially convenient for use at night or in low-light environments. Of course, depending on cost or the needs of specific application groups, charging port 3 can also be a regular USB interface.

[0048] The cutter head assembly 1 is a conventional technical means in this field and is not the inventive point of this utility model. Therefore, its specific structure will not be described in detail here.

[0049] For the razor of this utility model, please refer to [link / reference]. Figure 3 and Figure 4 The other end of the handle 2 is fixedly connected to a first limiting ring 32, which covers the first sealing member 5.

[0050] The first limiting ring 32 is integrally formed with the handle 2, and its inner side abuts against the outer circumferential side of the first sealing member 5, forming a limiting installation function for the first sealing member 5 and maintaining the stable sealing function of the first sealing member 5 on the charging port 3.

[0051] Based on the above embodiment, one end of the first limiting ring 32 is fixedly connected to the handle 2, and the other end extends toward the charging circuit board 31. Furthermore, the inner side of the other end of the first limiting ring 32 is provided with a bevel, which guides the insertion of the first sealing member 5 into the first limiting ring 32.

[0052] For the razor of this utility model, please refer to [link / reference]. Figures 3 to 10 The second sealing element 6 includes a sealing ring 61 detachable from the other end of the control switch 4 and a mounting ring 62 circumferentially fixed to the outer side of the sealing ring 61. The sealing ring 61 abuts against the main board 41. A slot 621 is provided on the outer side of the mounting ring 62. The handle 2 is provided with a locking block 23 that is adapted to and locked in the slot 621.

[0053] In this embodiment, the other end of the control switch 4 forms a first annular slot. One end of the sealing ring 61 is inserted into the first annular slot for installation, and the installation is achieved by interference fit to prevent them from disengaging. Furthermore, a second annular slot is formed between the inner side of the mounting ring 62 and the sealing ring 61. The other end of the control switch 4 is inserted into the second annular slot. The inner wall of the second mounting port 22 is located in the groove direction of the second annular slot, so that water seeping from the inner wall of the second mounting port 22 is blocked through the second annular slot, achieving a seal.

[0054] The bayonet 621 has a ring-shaped structure. During installation, the locking block 23 is inserted into the bayonet 621 to install the second sealing element 6. The locking block 23 has an internal mounting opening for the second sealing element 6 to pass through.

[0055] A fixing port 24 is provided on the outer side of the handle 2. The fixing port 24 is adapted to and fixedly installed with a fixing plate 25. A second mounting port 22 is provided on the fixing plate 25, and the locking block 23 is located in the opening of the fixing port 24. A first guide surface 622 inclined towards the main board 41 is provided on the outer side of the mounting ring 62.

[0056] During installation, force is applied to the second seal 6 to press it into the inner mounting opening of the locking block 23. Upon pressing, the first guide surface 622 abuts against the side of the locking block 23, providing a guiding effect. This causes the mounting ring 62 to deform under the reaction force until the locking block 23 is engaged in the locking slot 621. Afterward, the control switch 4 is installed on the second seal 6. Finally, the fixing plate 25 is fixedly installed in the fixing slot 24. During disassembly, force is applied to the fixing plate 25 to remove it. Then, force is applied to the second seal 6 to deform it and remove it.

[0057] The fixing plate 25 can be fixedly installed in the fixing port 24 with sealant to form a waterproof seal. One end of the control switch 4 is slidably connected to the inner wall of the second mounting port 22 so that when the control switch 4 is pressed, the force is transmitted to the sealing ring 61 of the second sealing member 6 through the control switch 4, and then to the main board 41 to realize the transmission of control signals.

[0058] Based on the above embodiment, the upper side of the mounting ring 62 protrudes and abuts against the inner side of the fixing plate 25 to support the fixing plate 25. At the same time, through this mutual abutment, a sealing effect is achieved on the second annular slot, reducing the possibility of water overflowing into the second annular slot.

[0059] For the razor of this utility model, please refer to [link / reference]. Figures 7 to 10 The control assembly also includes a motor 7 installed in the receiving cavity, a main board 41 connected to the motor 7 for communication, and the output end of the motor 7 connected to the cutter head assembly 1 for transmission; a sealing cover 8 is also installed in the receiving cavity, the sealing cover 8 covers the motor 7, one end of the sealing cover 8 is detachably connected to the cutter head assembly 1, the other end is detachably connected to the other end of the handle 2, and the other end of the sealing cover 8 has an opening to form a socket, the charging circuit board 31 is detachably connected to the sealing cover 8 and seals the socket, and the main board 41 is detachably connected to the outside of the sealing cover 8.

[0060] In this embodiment, the control assembly also includes a battery 71. The charging port 3 is electrically connected to the charging circuit board 31. The charging circuit board 31 receives electrical energy from an external power source (such as a charger) and converts it into voltage and current suitable for charging the battery 71 inside the shaver. The charging circuit board 31 is communicatively connected to the main board 41. The charging circuit board 31 transmits the charging status and battery 71 power information to the main board 41, while the main board 41 also controls the charging process through the charging circuit board 31. When the charger is plugged into the charging port 3 of the shaver, the external power source (usually the charger) inputs electrical energy to the charging circuit board 31 through the charging port 3. The charging circuit board 31 converts the input electrical energy into voltage and current suitable for charging the battery 71. The battery 71 stores the electrical energy, and the charging status of the battery 71 (such as power level and whether charging is complete) is fed back to the main board 41 through the charging circuit board 31. When the shaver needs to run (for example, when the user presses the control switch 4), the main board 41 obtains electrical energy from the battery 71 and transmits it to the motor 7 through the drive circuit (not shown in the figure), enabling the motor to rotate and drive the blades of the shaver assembly 1.

[0061] The charging circuit board 31 is detachably connected to the sealing cover 8 and seals the socket, allowing the charging circuit board 31 itself to function as a component of the control assembly. While performing charging and discharging functions, it also, in conjunction with the sealing cover 8, forms a third sealing structure to protect the motor 7. Furthermore, the main board 41 is detachably connected to the outside of the sealing cover 8. That is, the sealing cover 8 forms the base for the internal structure, providing a sealed installation of the motor 7 while stably mounting the main board 41 and the charging circuit board 31. The entire structure is compact, ensuring the shaver is small and easy to carry.

[0062] For the razor of this utility model, please refer to [link / reference]. Figures 7 to 10 The sealing cover 8 includes a cover body 81 and a clamping member 82. One end of the cover body 81 is detachably connected to the cutter head assembly 1, and the other end is detachably connected to the other end of the handle 2. One end of the clamping member 82 is detachably connected to the other end of the cover body 81, and the other end has an opening to form a socket. The charging circuit board 31 is detachably connected to the other end of the clamping member 82 and seals the socket. The main board 41 is detachably connected to the outside of both the cover body 81 and the clamping member 82. The two ends of the motor 7 are located inside the cover body 81 and the clamping member 82, respectively.

[0063] The other end of the cover 81 has a through-open structure to form a push-pull port so that the motor 7 can be installed inside the cover 81. Then, the clamping fastener 82 is installed and the charging circuit board 31 is installed to seal the port.

[0064] The cover 81 includes a sealing section 811 with one end open to the cutter head assembly 1 and detachably connected to the cutter head assembly 1, and a covering section 812 with one end fixedly connected to the other end of the sealing section 811. The outer side of the sealing section 811 abuts against the inner side of the handle 2, and one end of the motor 7 is located inside the covering section 812.

[0065] When in use, the covering section 812 and the clamping member 82 together form protection for the motor 7; and during this process, the outer side of the sealing section 811 abuts against the inner side of the handle 2, forming a sealing effect that reduces the possibility of water continuing to seep forward.

[0066] The outer opening at one end of the sealing section 811 forms a limiting groove, and the cover 81 also includes a limiting strip 813 installed in the limiting groove, with the limiting strip 813 abutting against the inner side of the handle 2.

[0067] The limiting strip 813 may be made of rubber material to improve the sealing effect of the contact surface between the outer side of the sealing section 811 and the inner side of the handle 2, thereby further reducing the possibility of water seepage.

[0068] Based on the above embodiments, one end of the sealing section 811 is fixedly connected to the slot 8112, and the cutter head assembly 1 has a snap-fit ​​section that is adapted to and snaps into the slot 8112, so as to realize the detachable connection between the sealing section 811 and the cutter head assembly 1.

[0069] The sealing section 811 forms a positioning surface 8111 on the other side; the cover 81 also includes two parallel positioning strips 814, one end of which is fixedly connected to the positioning surface 8111. The two positioning strips 814 open towards each other and each forms a limiting port 8141. The two limiting ports 8141 pass through the other end of the corresponding positioning strip 814. One end of the main board 41 abuts against the positioning surface 8111, and the other end abuts against the charging circuit board 31. The main board 41 is inserted into the two limiting ports 8141 at the same time.

[0070] During installation, after connecting the clamping fastener 82 to the cover 81, insert one end of the main board 41 into the limiting port 8141 of the two positioning strips 814, so that one end of the main board 41 abuts against the positioning surface 8111. Then, detachably connect the charging circuit board 31 to the other end of the clamping fastener 82 and seal it in the socket. This allows the positioning surface 8111, the charging circuit board 31, and the two positioning strips 814 to form a stable installation of the main board 41. At this time, the second mounting port 22 is located on the upper side of the main board 41, and the connecting surface of the clamping fastener 82 and the cover 81 is located on the lower side of the main board 41. The main board 41 can form a waterproof effect, preventing water from directly seeping into the sealed cover 8 from the connecting surface of the clamping fastener 82 and the cover 81.

[0071] The positioning surface 8111 of the sealing cover 8 has a through opening to form a rotating hole, so that the output shaft of the motor 7 can pass through and achieve a transmission connection with the cutter head assembly 1 through the transmission structure.

[0072] Based on the above embodiment, the positioning surface 8111 is fixedly connected to two opposing clamping plates 815, one of which has curved ends at the top and bottom to clamp and fix the battery 71 between the two clamping plates 815, thus completing the installation.

[0073] Furthermore, at least two first internally threaded posts 816 are fixedly connected to the outer side of the covering section 812. One end of each of the two first internally threaded posts 816 is fixedly connected to the covering section 812, and the other end extends along the insertion direction of the sealing cover 8 and extends to the inner side of the other end of the handle 2. The other end of each of the two first internally threaded posts 816 is provided with internal threads. The other end of the handle 2 has two first countersunk holes, and each is fitted with a first screw 8161. The two first screws 8161 are respectively inserted into the two first countersunk holes and threadedly connected to the two first internally threaded posts 816 to achieve the connection between the cover 81 and the handle 2.

[0074] For the razor of this utility model, please refer to [link / reference]. Figures 8 to 10 The socket of the clamping member 82 extends inward with an outer baffle 821, and at least two hooks 822 are fixedly connected to the other end of the clamping member 82. The charging circuit board 31 is locked in the space between the outer baffle 821 and the plane formed by each hook 822.

[0075] When the charging circuit board 31 is detachably connected to the other end of the clamping member 82 and sealed in the socket, the charging circuit board 31 is pressed into the space between the outer baffle 821 and the planes formed by each hook 822, thus realizing the installation of the charging circuit board 31. Furthermore, each hook 822 has a second guide surface 8221 on its outer side to guide the pressing of the charging circuit board 31. After the charging circuit board 31 is installed in place, it abuts against the end of the main board 41, thus limiting the position of the main board 41.

[0076] Based on the above embodiments, at least two corner clips 823 are fixedly connected to the other end of the clamping member 82. Specifically, there can be two, three, or four, with at least two of them being diagonally arranged. The corner clips 823 have an "L"-shaped structure. When the charging circuit board 31 is installed in place, the corner of the charging circuit board 31 enters the inner side of the corresponding corner clip 823 to limit the installation of the charging circuit board 31 and improve the installation stability of the charging circuit board 31.

[0077] The socket of the clamping fastener 82 extends inward with an inner baffle 824. The inner baffle 824 is spaced apart from the outer baffle 821 on the side away from the hook 822 and abuts against the tail of the motor 7. That is, when the motor 7 is installed in the cover 81 and then the clamping fastener 82 is installed, the inner baffle 824 abuts against the motor 7 to ensure the stable installation of the motor 7.

[0078] Based on the above embodiment, a receiving groove 817 is provided at the other end of the covering section 812, and one end of the clamping member 82 forms an overlapping platform 826 and is inserted into the receiving groove 817 to form a plug-in connection structure.
