[0036] 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:
[0037] This utility model discloses a mounting structure for a motor and a charging circuit board. Please refer to [link / reference]. Figures 7 to 10 The sealing cover 8 includes:
[0038] The cover 81 has a through-open structure, with a rotating hole at one end and a push-pull opening at the other end, for inserting the head end of the motor 7 into the cover 81 through the push-pull opening.
[0039] The clamping member 82 has a through-open structure. One end is detachably connected to the other end of the cover 81 for fitting onto the tail end of the motor 7. The other end of the clamping member 82 is used to press the tail end of the motor 7 and is also used for detachably installing the charging circuit board 31.
[0040] In this context, the "head end" of motor 7 refers to the end where its output shaft is located, while the "tail end" of motor 7 refers to the end opposite to the output shaft. Furthermore, the other end of the clamping member 82 has a through-open structure, forming a socket.
[0041] During installation, the first end of the motor 7 is inserted into the cover 81 through the push-pull port, allowing its output shaft to extend from the rotation hole. Then, one end of the clamping fastener 82 is detachably connected to the other end of the cover 81, so that the other end of the clamping fastener 82 presses against the tail end of the motor 7, thus fixing the motor 7. Then, the charging circuit board 31 is detachably installed on the other end of the clamping fastener 82, forming a seal on the other end of the clamping fastener 82. In this way, the clamping fastener 82 is used to simultaneously fix the motor 7 and the charging circuit board 31. Compared with the independent installation method in the prior art, the motor 7 and the charging circuit board 31 can be fixed at the same time through the clamping fastener 82. This installation method has a relatively simple structure, and it does not require disassembling and assembling multiple structures. Only the clamping fastener 82 needs to be disassembled and assembled. At the same time, the charging circuit board 31 is installed at the tail end of the motor 7 through the clamping fastener 82, which saves installation space and allows for miniaturization of the shaver.
[0042] The other end 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 outer baffle 821 is used to abut against one side of the charging circuit board 31, and each hook 822 is used to abut against the other side of the charging circuit board 31.
[0043] When the charging circuit board 31 is detachably connected to the other end of the clamping member 82, the charging circuit board 31 is pressed into the space between the outer baffle 821 and the plane formed by each hook 822, thereby realizing the installation of the charging circuit board 31.
[0044] The number of hooks 822 can be two, three, or four, etc.
[0045] Furthermore, each hook 822 has a second guide surface 8221 on its outer side to guide the pressing of the charging circuit board 31. When the charging circuit board 31, which is in contact with the second guide surface 8221, is subjected to continuous force, the hook 822 undergoes adaptive deformation until the charging circuit board 31 is inserted into the space between the outer baffle 821 and the plane formed by each hook 822.
[0046] At least two corner clips 823 are fixedly connected to the other end of the clamping device 82, and at least two corner clips 823 are arranged diagonally, each corner clip 823 being used to simultaneously abut against the adjacent sides of the charging circuit board 31.
[0047] In this embodiment, the corner clip 823 has 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.
[0048] Furthermore, the number of corner clips 823 can be two, three, or four, etc. The number of corner clips 823 and outer baffles 821 are equal and correspond one-to-one. In the figure, four of each are shown. The four outer baffles 821 support the four corners of the charging circuit board 31, and the four corner clips 823 limit the four corners of the charging circuit board 31.
[0049] The other end of the clamping fastener 82 is fixedly connected to 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 is used to abut against the tail end of the motor 7.
[0050] When the motor 7 is installed inside the cover 81 and the clamping fastener 82 is installed on the cover 81, the inner baffle 824 abuts against the tail of the motor 7, so that the motor 7 is installed stably by the joint limiting of the cover 81 and the inner baffle 824.
[0051] The other end of the cover 81 is provided with a receiving groove 817, which is an annular groove. One end of the clamping member 82 is formed with an overlapping platform 826, which is adapted to and inserted into the receiving groove 817. That is, when one end of the clamping member 82 is detachably connected to the other end of the cover 81, the overlapping platform 826 is inserted into the receiving groove 817 to achieve the connection between the clamping member 82 and the cover 81.
[0052] At least two second internally threaded posts 818 are fixedly connected to the outer side of the cover 81, and at least two connecting sleeves 825 are fixedly connected to the outer side of the clamping member 82. Each connecting sleeve 825 is detachably connected to each second internally threaded post 818 in a one-to-one correspondence. In this embodiment, each end of the second internally threaded post 818 is provided with an internally threaded hole, and each connecting sleeve 825 is provided with a countersunk hole, which is connected to the internally threaded hole of the corresponding second internally threaded post 818, so that a screw can be inserted from the countersunk hole, and the screw achieves a threaded connection with the second internally threaded post 818.
[0053] After the clamping fastener 82 is connected to the cover 81 by inserting the overlapping plate 826 into the receiving groove 817, each connecting sleeve 825 is connected to each second internal thread post 818, specifically by screws, so that the clamping fastener 82 is securely installed on the cover 81.
[0054] This utility model also discloses a razor; please refer to [link / reference]. Figures 1 to 10 The mounting structure, including the aforementioned motor and charging circuit board, also includes:
[0055] The handle 2 has an opening at one end to form a receiving cavity, and a first mounting port 21 that communicates with the receiving cavity is provided at the other end.
[0056] 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;
[0057] The control assembly includes a charging circuit board 31 and a motor 7. The motor 7 is installed in the housing 81 and the clamping fastener 82 of the motor and charging circuit board mounting structure. The charging circuit board 31 is detachably connected to the other end of the clamping fastener 82 and abuts against the other end of the charging port 3.
[0058] During installation, the first end of the motor 7 is inserted into the cover 81 through the push-pull port, allowing its output shaft to extend from the rotation hole. Then, one end of the clamping fastener 82 is detachably connected to the other end of the cover 81, pressing the other end of the clamping fastener 82 against the tail end of the motor 7 to secure it. Next, the charging circuit board 31 is detachably installed on the other end of the clamping fastener 82, sealing the insertion port on the other end of the clamping fastener 82. Finally, the motor 7, the sealing cover 8, and the charging circuit board 31 are all installed within the receiving cavity of the handle 2 to achieve a sealed installation. The charging circuit board 31 is installed at the tail end of the motor 7 via the clamping fastener 82, saving installation space and allowing for a smaller handle 2, making it more convenient to use.
[0059] Based on the above embodiments, the shaver also includes a blade assembly 1 and a first sealing member 5. One end of the handle 2 is open to form a receiving cavity and is detachably connected to one end of the blade assembly 1. The first sealing member 5 covers the charging port 3, with one end abutting against the inner side of the handle 2 and the other end abutting against the charging circuit board 31.
[0060] 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.
[0061] The side wall of the handle 2 is also provided with a second mounting port 22 that connects to the receiving cavity; the shaver also includes a 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; the control assembly also includes a main board 41, which is communicatively connected to the charging circuit board 31 and the motor 7, and the main board 41 is detachably connected to the sealing cover 8.
[0062] After detachably connecting one end of the clamping fastener 82 to the other end of the cover 81, before installing the charging circuit board 31, first detachably connect the main board 41 to the sealing cover 8, and then install the charging circuit board 31. In this way, the charging circuit board 31, the motor 7 and the main board 41 can be installed simultaneously through the cover 81, improving the installation integration.
[0063] The control switch 4 is covered with a second seal 6. One end of the second seal 6 abuts against the inside of the handle 2, and the other end abuts against the main board 41.
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] Based on the above embodiment, a first limiting ring 32 is fixedly connected to the inner side of the other end of the handle 2, and the first limiting ring 32 covers the first sealing member 5. 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 to the charging port 3. 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. The inner side of the other end of the first limiting ring 32 is provided with a bevel, so as to guide the installation of the first sealing member 5 into the first limiting ring 32 through the bevel.
[0069] Based on the above embodiments, the second sealing member 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 outside of the sealing ring 61. The sealing ring 61 abuts against the main board 41, and the mounting ring 62 has a slot 621 on its outer side. The handle 2 is provided with a locking block 23 that is adapted to and locked in the slot 621.
[0070] 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] For the razor of this utility model, please refer to [link / reference]. Figures 1 to 6 The cover 81 includes a sealing section 811 with one end open, a covering section 812 fixedly connected to the other end of the sealing section 811, and two positioning strips 814. The outer side of the sealing section 811 abuts against the inner side of the handle 2. The head end of the motor 7 is located inside the covering section 812. The other end of the sealing section 811 forms a positioning surface 8111. The two positioning strips 814 are arranged in parallel and one end 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.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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.
[0081] The control assembly also includes a battery 71 that is connected to the charging circuit board 31 and the main board 41. The battery 71 is electrically connected to the motor 7. The cover 81 includes two opposing clamping plates 815. One end of each clamping plate 815 is fixedly connected to the positioning surface 8111, and the upper and lower ends of one of the clamping plates 815 are arc plates. The battery 71 is clamped between the two clamping plates 815.
[0082] In this embodiment, 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 internal battery 71 of the shaver. The charging circuit board 31 is communicatively connected to the main board 41, transmitting the charging status and battery 71 power information to the main board 41. Simultaneously, the main board 41 also controls the charging process through the charging circuit board 31. When the charger is plugged into the shaver's charging port 3, 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 (e.g., 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 a drive circuit (not shown in the figure), enabling the motor to rotate and drive the blades of the shaver assembly 1.
[0083] 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.
[0084] Based on the above embodiment, 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 is provided with two first countersunk holes, and each is provided 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.
[0085] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
