5. SPECIFIC EMBODIMENT OF THE INVENTION

All the features disclosed in the specification, or all disclosed methods or steps in the process, except for mutually exclusive features and/or steps, can be combined in any manner.


Any feature disclosed in the specification (including any appended claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or equivalent alternative features. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.


As shown in FIG. 1, a magnetic shaver according to the invention, comprising: a connecting part 5, wherein the connecting part 5 is detachably connected to the device host, and the device host is provided with a control mainboard and a power supply;


it further comprises a bottom shell 4, wherein the bottom shell 4 is installed on the connecting part 5; the connecting part 5 and the bottom shell 4 are provided with a gear driving mechanism, and the gear driving mechanism is powered and controlled by the device host;


it further comprises a cutter head assembly, wherein the cutter head assembly is magnetically connected and assembled with the bottom shell 4 through a magnetic structure; when the cutter head assembly is installed on the bottom shell 4, the gear driving mechanism drives the cutter head assembly;


as shown in FIGS. 6 and 9, it further comprises magnetic opening and closing members 6, which are separately arranged on the outer circumferential surface of the cutter head assembly; when it is necessary to remove the cutter head assembly, press the magnetic opening and closing members 6, or directly manually separate the cutter head assembly. When disassembling the cutter head assembly, the user does not need to press down the magnetic opening and closing member 6, or the user can use manpower to separate the cutter head assembly from the bottom shell 4. However, when the magnetic opening and closing member 6 is not pressed down, it requires a larger force to remove the cutter head assembly, and then the cutter head assembly can also be separated. Although the cutter head assembly can be forcibly disassembled in this way, it exerts a large force on the cutter head assembly and is not suitable for long-term operation. Therefore, when disassembling the cutter head assembly, manually pressing down the magnetic opening and closing member 6 can reduce the magnetic attraction between the cutter head assembly and the bottom shell 4, making it easier to disassemble the cutter head assembly. Under normal circumstances, the cutter head assembly and the bottom shell 4 have very good magnetic attraction and are not easy to separate.


As shown in FIG. 8, the bottom shell 4 is provided with a docking panel 8 on one side opposite to the cutter head assembly, and the docking panel 8 is provided with a boss 19 corresponding to the position of the cutter head assembly; the drive shafts of the gear driving mechanism all pass through the boss 19 and extend to the outside of the docking panel; after the cutter head assembly is disassembled relative to the bottom shell 4, the docking panel 8 of the bottom shell 4 will be exposed, and one end of the cutter head assembly will expose the driving part of the cutter head; during installation, position and assemble the docking panel 8 of the bottom shell 4 and the cutter head assembly, and then magnetically attract them to complete the installation;


as shown in FIGS. 3 and 4, a plurality of first magnetic grooves 13 are arranged annularly on the side of the docking panel 8 away from the cutter head assembly, and each of the first magnetic groove 13 is embedded with a first magnetic block; the docking panel 8 and the bottom shell 4 are assembled with each other.


As shown in FIG. 5, the gear driving mechanism comprises a central driving wheel 14, transmission gears 15, and driven gears 16; the driven gears 16 are circumferentially arranged on a gear bracket 7 provided in the bottom shell 4; the central driving wheel 14 is installed at the center of the gear bracket 7, and the central driving wheel 14 is driven by a driving motor; one side of each of the driven gear 16 is driven by meshing with the central driving wheel 14 through the transmission gear 15, and each of the driven gear 16 and the central driving wheel 14 is provided with a drive shaft; the drive shaft passes through the docking panel 8 and is provided with a drive block 18, and each of the drive block 18 corresponds to a driving installation port of the cutter head assembly. When assembling, align the drive installation port of the cutter head assembly with the drive block 18 to complete the power connection. During operation, the driving motor rotates to drive the central driving wheel 14 to rotate, and the central driving wheel 14 rotates to drive each transmission gear 15 to rotate. The rotation of each transmission gear 15 drives the driven gear 16 to rotate, so the driven gear 16 and the central driving wheel 14 rotate together, thereby driving the drive shaft to rotate. After the drive shaft is connected to the cutter head assembly, each cutting blade of the cutter head assembly can be driven to rotate.


As shown in FIGS. 3, 4, and 10, the cutter head assembly comprises a face shell 3, fixing panels 2, cutter nets 1, cutting blades 10, elastic brackets 9, and connecting brackets 12; the elastic bracket 9 is installed in the face shell 3 and snap-connected to the face shell 3; the fixing panel 2 is installed on the face shell 3, and the cutter net 1 is installed on the fixing panel 2; the cutting blade 10 is arranged corresponding to each cutter net 1; the bottom of each of the cutting blade 10 is provided with a connecting bracket 12, and the driving installation port is formed at the bottom of the connecting bracket 12; after the cutter head assembly is assembled with the bottom shell 4, the driving block 18 is installed into the driving installation port and drives the cutting blade 10 to perform cutting action, as shown in FIG. 7;


the elastic bracket 9 is provided with a second magnetic groove 11 corresponding to each of the first magnetic groove 13, and the second magnetic groove 11 is embedded with a second magnetic block 17; the first magnetic block is magnetically attracted to the magnetic block 17 on the docking panel 8, and the elastic brackets 9 of several magnetic blocks 17 are provided with magnetic opening and closing members 6. After the cutter head assembly is assembled, the first magnetic block and the magnetic block 17 are aligned and magnetically attracted, so that the magnetic attraction between the cutter head assembly and the bottom shell 4 can be achieved. The first magnetic block and the magnetic block 17 can both be arranged in a circle, and there can be a sufficiently high magnetic attraction force between the first magnetic block and the magnetic block 17. Since there is a magnetic opening and closing member 6, when disassembling, just press the magnetic opening and closing member 6 to reduce the magnetic attraction force and facilitate the removal of the cutter head assembly.

After the first magnetic block and the magnetic block 17 are far away, the magnetic attraction force can be reduced, so that the cutter head assembly can be separated and removed better.


In the embodiment, as shown in FIG. 2, the magnetic opening and closing members 6 are provided to be three, and the number of the magnetic opening and closing members 6 is smaller than the number of the magnetic blocks 17; the magnetic opening and closing members 6 are arranged in a triangular shape in the groove opened outside the face shell 3. During operation, use thumb, index finger and middle finger to buckle into the corresponding grooves in a triangular shape, and then press down on the magnetic opening and closing member 6, so that the first magnetic block can be moved away from the second magnetic block 17, and the cutter head assembly can be removed at this time.


The above are only specific embodiments of the invention, but the protection scope of the invention is not limited thereto. Any modifications or substitutions creative efforts shall all fall within protection scope of the invention.
