Detailed Description

The following description will be made in conjunction with the accompanying drawings.

As a specific example, the floating cutter head structure of the embodiment of the present invention includes a cutter head assembly 2, a body 1 provided with an output shaft 11 and a floating mount 4; the cutter head assembly 2 is connected to the output shaft 11.

Generally, the body 1 is provided with an output device 118, and the output shaft 11 is connected with the output device 118, so that the output device 118 can rotate the output shaft 11 to output power. The output device 118 may be a motor, or may be a gear driven by a motor.

Generally, a lifting spring 119 is disposed in the output shaft 11, and both ends of the lifting spring 119 respectively abut against, so that the output shaft 11 can lift (i.e., conventional floating in the vertical direction can be achieved; in order to avoid confusion with the following "floating", the conventional floating in the vertical direction is referred to as lifting).

As a prior art, the cutter head assembly 2 comprises a shaving assembly 29, the shaving assembly 29 comprises a blade member 291 and a cutter net 292; the output shaft 11 is inserted into the bottom end of the blade member 291 so as to drive the blade member 291 to rotate; hairs and the like are cut by the rotating blade members 291 after passing through the blade net 292 to achieve shaving. Generally, the top end of the output shaft 11 has a triangular cross section, and a gap is provided between the top end of the blade member 291 and the bottom end of the blade member 291, so that the blade member 291 can move relative to the output shaft 11 while the output shaft 11 drives the blade member 291 to rotate.

A float member 3 is also included.

The floating member 3 comprises a swing arm 31 and an elastic part 32, one end of the swing arm 31 is hinged with the floating mounting member 4, and the other end of the swing arm 31 is fixedly connected with the cutter head component 2.

The elastic portion 32 is connected to the swing arm 31 and the floating mount 4, respectively, so that the other end of the swing arm 31 tends to move away from the body 1 and maintains a position relative to the body 1. For example, the other end of the swing arm 31 is held in position with respect to the body 1 by virtue of the extreme position of the elastic force provided by the elastic portion 32; of course, the oscillating arm 31 can also be shown in other ways in its holding position with the body 1.

The working principle is that when the shaver is used and the knife net 292 of the knife head component 2 is attached to the skin of a human body, the pressure of the skin of the human body and the like on the knife head component 2 enables the knife head component 2 to rotate to swing, and the skin of the human body and the like can be tightly attached to the knife net of the knife head component 2. When the skin of the human body is separated from the cutter head component 2, the cutter head component 2 is reset and maintained.

That is, the cutter head assembly 2 is hinged to the body 1 by the swing arm 31, and the other end of the cutter head assembly 2 tends to move away from the body 1 and maintains a position relative to the body 1; thereby can make tool bit subassembly 2 rotatory and realize the swing, ensure that human skin etc. can closely laminate with tool bit subassembly 2's sword net, ensure to shave the effect and shave the experience.

Preferably, the elastic portion 32 is a spring, the swing arm 31 is substantially perpendicular to the axis of the elastic portion 32, and the elastic portion 32 is fixedly connected to the floating mount 4, so that one end of the swing arm 31 is hinged to the floating mount 4, and the other end of the swing arm 31 tends to move away from the main body 1. One end of the swing arm 31 is hinged to the floating mount 4 without a pin or the like, which is advantageous for simplifying the structure and reducing the cost.

Further, the floating member 3 further includes a torsion arm 33 fixedly connected to the other end of the swing arm 31 and having elasticity, and the torsion arm 33 is substantially parallel to the axial line of the elastic portion 32 and fixedly connected to the cutter head assembly 2. During shaving, the cutter head assembly 2 can rotate to realize twisting (see fig. 10), so that the skin of a human body and the like can be tightly attached to the cutter mesh of the cutter head assembly 2, and the shaving effect and the shaving experience are ensured.

Further, the floating member 3 comprises two swing arms 31 and two elastic parts 32, and the other ends of the two swing arms 31 are fixedly connected through a torsion arm 33; the floating mount 4 includes floating connection parts 41 which are floating connection grooves 411, and the elastic parts 32 are inserted into the floating connection grooves 411, respectively.

When the floating member 3 is assembled, the torsion arm 33 is bent to make the two elastic parts 32 away from each other, and then the two elastic parts 32 respectively aim at the floating connecting groove 411 and then the torsion arm 33 is reset, so that the elastic parts 32 can be respectively inserted into the floating connecting grooves 411 to complete the assembly of the floating member 3, that is, the assembly of the floating member 3 is convenient.

Further, a limit wall 412 is fixedly disposed in the floating connection slot 411, and one end of the elastic portion 32 abuts against the limit wall 412, so that a gap is formed between the swing arm 31 and the floating installation component 4. It is possible to ensure that the gap between the swing arm 31 and the floating mount 4 is relatively stable, thereby ensuring that the swing arm 31 and the floating mount 4 do not interfere with each other.

Further, the floating installation member 4 is detachably connected with the fuselage 1; the bottom end of the floating coupling groove 411 is exposed from the floating mount 4. Generally, the body 1 is provided with a connecting shaft 19, the floating mount 4 is provided with a body coupling groove 49, and the connecting shaft 19 is interference-fitted or screw-coupled with the body coupling groove 49, thereby making the floating mount 4 detachably coupled with the body 1. The two elastic parts 32 can enter the floating connecting groove 411 from the bottom end of the floating connecting groove 411 respectively, the assembly of the floating part 3 can be completed without bending the twisting arm 33, and meanwhile, the floating part 3, the floating installation part 4 and the cutter head assembly 2 can be preassembled into a whole, so that the assembly is convenient.

Facilitating assembly between the float member 3 and the cutter head assembly 2.

Preferably, the cutter head components 2 are two and mirror images of each other, and the two cutter head components 2 are approximately mutually abutted at a mirror plane. The elastic portion 32 can keep the cutter head assembly 2 in position relative to the body 1 even if it provides a large elastic force; therefore, the elasticity of the elastic part 32 can be set arbitrarily according to the requirement, which is beneficial to ensuring the shaving effect and the shaving experience. Generally, the two knife nets 292 are arranged in a V-shape to match with the chin of the human body, etc.

Further, the floating installation member 4 is fixedly provided with a segmental guide body 43; the cutter head assembly 2 is provided with guide grooves 213 in mirror symmetry, which engage with the guide body 43. The tool bit component 2 can be guided by swinging and twisting.
