[0024] The embodiments of the utility model are further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-2 As shown, a floating shaver comprises a body 10 and a floating shaver head mounted on the body 10.

[0026] Among them, the body 10 is usually equipped with a power supply, a motor, a circuit board, etc. The floating shaver head is detachably mounted on the body 10 and can be coupled with the output end of the motor. The motor can drive the floating shaver head to achieve automatic shaving action.

[0027] like Figure 2-7 As shown, the floating razor head includes a head cover assembly 20 and a bottom shell assembly 30, and the head cover assembly 20 is floatingly connected to the bottom shell assembly 30.

[0028] The head cover assembly 20 includes a partition 1, a knife net frame 2 installed on the partition 1, and a cutting unit 3 arranged on the knife net frame 2. The cutting units 3 are provided in three groups and are evenly distributed in the circumferential direction. The cutting units 3 include a knife net 31 and a movable knife 32 that is kept in contact with the knife net 31. The knife net 31 is connected to the knife net frame 2 in a floating manner.

[0029] In addition, the knife grid frame 2 is detachably connected to the partition 1, and the detachable connection is achieved by magnetic attraction. A plurality of first mounting grooves 21 are provided at the bottom of the knife grid frame 2, and a plurality of second mounting grooves 11 are provided at the bottom of the partition 1. The first mounting grooves 21 correspond to the second mounting grooves 11, and the first mounting grooves 21 and the second mounting grooves 11 are both provided with magnetic components that can attract each other, and the magnetic components are magnets or other magnetic materials. For example, a magnet is fixedly installed in the first mounting groove 21, and a magnet can also be installed in the second mounting groove 11, or other magnetic materials that can generate attraction with the magnet. The knife grid frame 2 can be reliably and stably installed on the partition 1 through the attraction between the two, and the disassembly and assembly operation is more convenient, which is convenient for hair cleaning.

[0030] The bottom shell assembly 30 includes a bottom shell 4 and a transmission unit 5 disposed in the bottom shell 4. The bottom shell 4 is detachably connected to the body 10, and the transmission unit 5 includes a bracket 51, an input gear 52, an output gear 53, an output shaft 54, and a coupling shaft head 56. The bracket 51 is fixedly installed in the bottom shell 4, and the input gear 52 and the output gear 53 are rotatably installed on the bracket 51. The output gear 53 is provided with three and is evenly distributed along the central circumference of the input gear 52, and the output gear 53 and the input gear 52 are meshed and transmitted with each other, and the coupling shaft head 56 is connected to the input gear 52, and it can be coupled and connected with the output end of the motor in the body, and the output shaft 54 ​​is connected to the output gear 53, and it passes through the partition 1 and is in transmission connection with the movable knife 32 of the cutting unit 3.

[0031] The output gear 53 is provided with a first connection frame 531, the first connection frame 531 is provided with a first slide groove 532, the outer wall of the output shaft 54 ​​is provided with a first slide plate 541 slidably matched with the first slide groove 532, and a second elastic member 55 is provided between the output shaft 54 ​​and the output gear 53, the second elastic member is specifically a spring, and is arranged between the output gear 53 and the output shaft 54. Since the knife net 31 is arranged to float relative to the knife net frame 2, the above structure is adopted so that the output shaft 54 ​​can float relative to the output gear 53, which can not only stably fit the movable knife 32 with the knife net 31, but also ensure the floating effect of the cutting unit, which is more close to the surface and improves the shaving effect.

[0032] In addition, the input gear 52 is provided with a second connection frame 521, the second connection frame 521 is provided with a second slide groove 522, the outer wall of the coupling shaft head 56 is provided with a second slide plate 561 that is slidably matched with the second slide groove 522, and a third elastic member 57 is provided between the coupling shaft head 56 and the input gear 52. The third elastic member 57 is also a spring and is arranged between the input gear 52 and the coupling shaft head 56. Since the cutter head is detachably connected to the body, the above structure is adopted so that the coupling shaft head 56 can float relative to the input gear 52, thereby ensuring that the coupling shaft head 56 can be coupled to the output end of the motor in the body.

[0033] When shaving, the motor starts, and its output end can drive the input gear 52 to rotate through the coupling shaft head 56, and the input gear 52 can drive the three output gears 53 to rotate, and the output gear 53 drives the movable knife 32 to rotate through the output shaft 54, thereby realizing automatic cutting and shaving action.

[0034] The partition 1 is connected to the bottom shell 4 via a floating ring 6, and a first elastic member 7 for floatingly supporting the partition 1 is connected to the bottom of the partition 1. The floating ring 6 can be made of soft materials such as silica gel to achieve a soft connection between the partition 1 and the bottom shell 4, so that the head cover assembly can float relative to the bottom shell assembly. During shaving, the head cover assembly can swing freely relative to the bottom shell assembly according to the facial shape, and combined with the floating effect of the cutting unit itself, double floating can be achieved, thereby achieving a better face-fitting effect, and then achieving a better shaving effect.

[0035] Among them, the first elastic member 7 is a spring, and the bracket 51 is integrally formed with a plurality of positioning posts 511 with grooves, and the positioning posts 511 correspond to the second mounting groove 11 at the lower end of the partition 1. The lower end of the first elastic member 7 is installed in the groove of the positioning post 511, and the upper end extends into the second mounting groove 11, which can not only limit the first elastic member 7, ensuring that the first elastic member 7 itself is stably installed and will not accidentally fall out, but also the first elastic member 7 can limit the magnetic attraction component in the second mounting groove 11, ensuring that it is stably installed and will not accidentally fall out, thereby achieving a more stable and reliable structure. Of course, the first elastic member 7 itself can also be directly used as a magnetic attraction component to achieve the purpose of mutual attraction with the magnet in the first mounting groove 11.
