[0038] Example 1:

[0039] This embodiment provides a shaver, which includes a reciprocating drive device 1 and a shaver head assembly (not shown in the figure). The reciprocating drive device 1 has a drive housing 11 disposed on the outside. Inside the drive housing 11 are a drive module for driving the shaver head assembly and a power module for supplying power to the drive module. The shaver head assembly is detachably mounted on the reciprocating drive device 1 and operates under the drive of the reciprocating drive device 1. The drive housing 11 also has a switch button 12, a charging port 15, and may also be equipped with a wireless charging module 16, such as... Figure 1 As shown, charging can be performed by simply placing the drive unit 1 or the entire shaver directly on the wireless charging module 16. The drive housing 11 is a hollow shell structure with an opening at the top, covered by a cover plate 13.

[0040] like Figure 2 and Figure 3 As shown, the drive module mainly includes a drive body 5 installed inside the drive housing 11, at least one drive seat 6, and at least one drive component 60. The drive body 5 contains at least one output seat 51, the drive seat 6 is separately disposed on the output seat 51, and the drive component 60 is integrally formed on the drive seat 6 for connecting to the moving tool holder 33 of the moving tool assembly. Under the action of the drive body 5, the moving tool holder 33 can reciprocate in the left-right direction. Integrating the drive component connected to the moving tool holder with the drive seat makes the structure more compact and robust, facilitates disassembly and assembly, simplifies the structure, and is conducive to miniaturization and lightweight development. Preferably, the drive component and the drive seat are integrally formed from the same material, making manufacturing more convenient and simple.

[0041] A first mounting portion 52 is formed on the output base 51, and a second mounting portion 61 is formed on the drive base 6. The first mounting portion 52 and the second mounting portion 61 are fixed together by fasteners 62 (such as bolts or screws). A mounting groove 63 is formed on the side of the second mounting portion 61 facing away from the first mounting portion 52. One of the drive members 60 includes a pair of drive rods 64 symmetrically arranged on both sides of the mounting groove 63. A gap is formed between the pair of drive rods 64, and the upper ends of the pair of drive rods 64 can be inserted into the same moving tool holder 33, thereby achieving connection with the moving tool holder 33. A support spring 65 for supporting the moving tool holder 33 is installed in the gap. The lower end of the support spring 65 is installed in the mounting groove 63, and a spring fixing piece 651 is fixed to the upper end. The spring fixing piece 651 is located in the gap between the pair of drive rods 64 and can be installed into the moving tool holder 33.

[0042] Other driving components can be such as Figure 4The drive rod 66 shown is integrally formed on the drive base 6 and is set on the front and rear sides of the mounting groove 63 along the front and rear directions. It can be used to connect a moving tool holder 33.

[0043] The drive body 5 also includes at least one output section 53, and the reciprocating drive device 1 further includes a drive section 7 and a drive component 70. The drive section 7 is integrally mounted on the output section 53, and the drive component 70 is integrally formed on the side of the drive section 7 opposite to the output section 53. A mounting groove 71 is formed on the side of the drive section 7 opposite to the first mounting section 52. The drive component 70 includes a pair of drive posts 72 symmetrically arranged on both sides of the mounting groove 71. A support spring 73 for supporting the moving tool holder 33 is installed in the mounting groove 71. The lower end of the support spring 73 is disposed in the mounting groove 71, and the upper end is provided with a spring fixing piece 731, which can be installed into the moving tool holder 33. The drive section 7 may also have an integrally formed or separately mounted drive pin 74. Figure 4 In the middle, the drive pin 74 is installed on the drive unit 7 using a split-clamp method.

[0044] The drive device of this embodiment can be adapted to five tool sets, with at least two or three of them mounted on the drive base 6 via a drive member. Each tool set has an inner moving tool assembly and an outer stationary tool assembly. The moving tool assembly includes a moving tool holder and a moving blade mounted on the moving tool holder. The stationary tool assembly includes a stationary blade disposed outside the moving blade and a stationary tool holder for mounting the stationary blade. Specifically, as shown... Figure 4 As shown, these five tool sets have five movable tool holders arranged side-by-side in the front-rear direction, namely, first movable tool holder 33a, second movable tool holder 33b, third movable tool holder 33c, fourth movable tool holder 33d, and fifth movable tool holder 33e, arranged from front to back. A drive unit 6 is located on the rear side in the front-rear direction and cooperates with three of the five movable tool holders, namely, the fifth movable tool holder 33e, the fourth movable tool holder 33d, and the third movable tool holder 33c, arranged from back to front in the front-rear direction. A drive unit 7 is located on the front side in the front-rear direction and cooperates with the other two movable tool holders, namely, the second movable tool holder 33b and the first movable tool holder 33a, arranged from back to front in the front-rear direction.

[0045] A pair of drive rods 66 are provided on the drive base 6, arranged along the front and rear sides of the support spring 65. The drive rod 66 on the front side is connected to the third moving tool holder 33c, and the drive rod 66 on the rear side is connected to the fifth moving tool holder 33e. The pair of drive rods 64 are connected together to the fourth moving tool holder 33d. At the same time, the support spring 65 between the pair of drive rods 64 is fixed to the middle of the fourth moving tool holder 33d by the spring fixing piece 651, thus supporting the fourth moving tool holder 33d.

[0046] A drive rod 74 is provided on the drive unit 7, located in front of the support spring 73 along the front-rear direction. The drive rod 74 is connected to the first movable tool holder 33a. A pair of drive columns 72 are connected to the second movable tool holder 33b. At the same time, the support spring 73 between the pair of drive columns 72 is fixed to the middle of the second movable tool holder 33b by a spring fixing piece 731, thus supporting the second movable tool holder 33b. Since the second movable tool holder 33b and the fourth movable tool holder 33d are connected to the support spring 65 and the support spring 73 respectively, they can float up and down in the height direction. The other movable tool holders can float in the height direction by the movable tool springs installed on their respective movable tool holders.

[0047] The drive body 5 also includes a coil 54, a vibration frame 55, a permanent magnet, and a reset component. The coil 54 is installed inside the drive housing 11, and the vibration frame 55 is located outside the coil 54. It houses a first vibration part 551 and a second vibration part 552, each with one end integrally formed and the other end separate. The first vibration part 551 is located on the front side in the front-rear direction and is fixed to the output base 51 with screws. The second vibration part 552 is located on the rear side in the front-rear direction and is fixed to the output part 53 with screws. Both the first vibration part 551 and the second vibration part 552 are located above the coil 54, and a permanent magnet is fixed to the side of the first vibration part 551 and the second vibration part 552 facing the coil 54. Figure 2 As shown, the reset member is a C-shaped reset part formed on both sides of the first vibration part 551 and the second vibration part 552 in the left and right directions. The open end of the C-shaped reset part is combined with the upper separation point of the first vibration part 551 and the second vibration part 552, and the closed end of the C-shaped reset part is located at the bottom. The C-shaped reset part is used to assist the first vibration part 551 and the second vibration part 552 in resetting during the vibration process.

[0048] like Figure 5 As shown, the battery module has a battery 81 and a controller 82. A mounting frame 14 is installed inside the drive housing 11. The battery 81 is detachably installed on both sides of the mounting frame 14. The controller 82 is installed at the bottom of the mounting frame 14. The mounting frame 14 is hollow inside. The coil 54 and the vibration frame 55 of the drive body 5 are both installed inside the frame 14.

[0049] In this embodiment, an output base 51 is mounted on the first vibration part 551, and an output part 53 is mounted on the second vibration part 552. After being powered on, the first vibration part 551 and the second vibration part 552 on the vibration frame 55 vibrate back and forth in the left and right direction through the principle of electromagnetic induction, thereby causing each moving blade holder to move left and right to achieve a shaving effect. The reciprocating drive device 1 and the blade head device can be detachably installed by setting a magnetic block. That is, the drive housing 11 of the reciprocating drive device 1 is provided with a first magnetic block, and the blade head device is provided with a second magnetic block. The first magnetic block and the second magnetic block attract each other, and the magnetic disassembly structure is simple and convenient.

[0050] Example 2:

[0051] This embodiment is basically the same as Embodiment 1 above, except that: Figure 6 As shown, the reset component consists of four reset springs, including a pair of first reset springs 56 respectively pressed between the two ends of the first vibrating part 551 and the inner wall of the mounting frame 14, and a pair of second reset springs 57 respectively pressed between the two ends of the second vibrating part 552 and the inner wall of the mounting frame 14, facilitating the reset of the first vibrating part 551 and the second vibrating part 552. Using reset springs for reset is not only simple in structure and low in cost, but also convenient to install, and provides good reset effect, improving work efficiency.

[0052] Example 3:

[0053] like Figures 7-12 As shown, this embodiment is basically the same as Embodiments 1 and 2 above, with only slight differences in the drive module. Structures identical to those in Embodiment 1 are represented by the same reference numerals in the accompanying drawings. Specifically, this embodiment proposes a shaver comprising a reciprocating drive device 1 and a blade head device 2. The reciprocating drive device 1 has a drive housing 11 located on the outside. Inside the drive housing 11 are a drive module for driving the blade head device 2 and a power module for supplying power to the drive module. The blade head device 2 is detachably mounted on the reciprocating drive device 1 and operates under its drive. The drive housing 11 also has a switch button 12, a charging port 15, and can also be configured with a wireless charging module. During charging, the drive device 1 or the entire shaver can be placed directly on the wireless charging module. The drive housing 11 is a hollow shell structure with an opening at the top, covered by a cover plate 13.

[0054] The shaver in this embodiment is equipped with five blade sets along the front-to-back direction. The drive module mainly includes a drive body 5 installed inside the drive housing 11, two drive seats 6, and five drive components 60 corresponding to the five blade sets. The drive body 5 contains two output seats 51a and 51b, and the two drive seats 6 are separately mounted on the two output seats 51a and 51b. Of the five drive components 60, two drive components 60 are integrally formed on one drive seat 6a, and the remaining three drive components 60 are formed on the other drive seat 6b. Each drive component 60 is connected to a blade set, and the blade set contains a moving blade assembly. The moving blade assembly has a moving blade seat 33, and the drive component 60 is connected to the moving blade seat. Under the action of the drive body 5, the moving blade seat 33 can reciprocate in the left-right direction. Integrating the drive components connected to the moving blade seat with the drive seats makes the structure more compact and robust, facilitates disassembly and assembly, simplifies the structure, and is conducive to miniaturization and lightweight development. Preferably, the drive component and the drive base are integrally formed from the same material, making production and manufacturing more convenient and simple.

[0055] The two drive terminals and their corresponding output terminals have the same mounting structure. Taking one of them as an example, for instance... Figure 10 As shown, a first mounting portion 52 is formed on the output base 51, and a second mounting portion 61 is formed on the drive base 6. The first mounting portion 52 and the second mounting portion 61 are fixed together by fasteners (such as bolts or screws, not shown in the figure). A pair of mounting grooves 63 for mounting fasteners are formed on the side of the second mounting portion 61 facing away from the first mounting portion 52. One of the drive members 60 is a drive rod 64a formed between the pair of mounting grooves 63. The upper end of the drive rod 64a can be inserted into the movable tool holder 33 of a tool set, thereby realizing the connection with the movable tool holder 33 of the tool set. The remaining drive components 60 consist of two drive rods 64b formed beside a pair of mounting grooves 63. A gap exists between these two drive rods 64b, within which a support spring 65 for supporting the corresponding blade assembly is installed. A second mounting portion 61, located within this gap, also provides a guide rod 67. The support spring 65 is sleeved around the guide rod 67, and a spring washer 68 is also provided between the two drive rods 64b. One end of the support spring 65 abuts against the second mounting portion 61, and the other end abuts against the spring washer 68. The guide rod 67 can be a metal rod, with one end connected to the drive seat 6 and the other end connected to the spring washer 68. During manufacturing, the metal rod can be placed in a mold, and then the drive seat 6 is integrally formed by injection molding the metal rod onto the outside of the metal rod.

[0056] Both drive rods 64b extend into the moving tool holder of the corresponding tool set and connect with the moving tool holder 33, such as... Figure 13As shown, the moving tool holder 33 has a pair of insertion holes 331 in the middle, which correspond one-to-one with the two drive rods 64b and allow the upper ends of the drive rods 64b to be inserted. Between the pair of insertion holes 331 is a guide portion 332 corresponding to the guide rod 67. The guide portion 332 has a guide hole in the middle for the upper end of the guide rod 67 to be inserted. The upper end face of the spring washer 68 abuts against the lower end face of the guide portion 332. When the tool assembly moves downwards during operation, the moving tool holder 33 can push the spring washer 68 downwards, causing the support spring 65 to compress. When the compressed support spring 65 returns to its original position, it can push the moving tool holder upwards, thus realizing the vertical movement of the moving tool holder and ensuring that the moving blade mounted on the moving tool holder is always in close contact with the stationary blade. Figure 11 As shown, the drive base 6a has two drive members, with the outer drive members being the aforementioned pair of drive rods 64b and the inner drive member being the aforementioned drive rod 64a; the drive base 6b has three drive members, with the two outer drive members being the aforementioned pair of drive rods 64b and the inner (middle) drive member being the aforementioned drive rod 64a. These five drive members are arranged side by side, each corresponding to the moving tool holder of one of the five tool groups, thereby realizing the reciprocating drive of the tool groups by the reciprocating drive device 1.

[0057] In this embodiment, both drive seats are integrally molded with the drive components, which simplifies the structure of the drive device, making disassembly and assembly more convenient and enabling the miniaturization and weight reduction of shavers, thus greatly improving the user experience.

[0058] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
