Description

Tool bit and have electric shaver of this tool bit

Technical Field

The application relates to the field of shavers, in particular to a shaver head and an electric shaver with the shaver head.

Background

With the development of our society, people are pursuing living quality more and more, more and more people begin to pay attention to their own image, and the shaver is an important image-tidying electric appliance for men.

The common shaver comprises a shaver body, a rotating motor and a battery are installed in the shaver body, the battery is used for supplying power to the rotating motor, a movable cutter is connected to an output shaft of the rotating motor, a blade used for shaving is arranged on the movable cutter, a mesh enclosure covering a cutter head is connected to the outer side wall of the shaver body in a threaded mode, the mesh enclosure is used for reducing the probability that a user is cut by the blade, and a plurality of additionally-increased fixing pieces used for fixing the position of the movable cutter are arranged on the inner side wall of the mesh enclosure.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: when a common shaver is installed, the movable knife needs to be placed into the mesh enclosure firstly, then the fixing piece is installed on the inner wall of the mesh enclosure, and finally the movable knife is installed on the output shaft of the rotating motor, so that the installation process is complicated.

SUMMERY OF THE UTILITY MODEL

In order to improve the loaded down with trivial details problem of installation process of tool bit, this application provides a tool bit and has electric shaver of this tool bit.

The application provides a pair of tool bit and have electric shaver of this tool bit adopts following technical scheme:

a cutter head comprises a movable cutter and a mesh enclosure, wherein the mesh enclosure is used for wrapping the movable cutter, a plurality of sawtooth blocks are arranged on the side wall of the edge of the movable cutter, a clamping ring is arranged on the inner side wall of the mesh enclosure, and the diameter of the side wall of the inner ring of the clamping ring is larger than that of the movable cutter and smaller than the rotating diameter of the sawtooth blocks.

By adopting the technical scheme, when the movable knife is required to be installed in the mesh enclosure, the movable knife is only required to be obliquely placed in the mesh enclosure, then the movable knife is placed rightly, and the sawtooth blocks are abutted against the side wall of the clamping ring to realize the installation of the movable knife, so that the installation is convenient and rapid; through sawtooth block butt on the joint ring, make the sword be difficult to follow the screen panel and drop, increased the stability of moving the sword, thereby reduced and moved the sword and drop from the screen panel and cause the probability of injury to the user, increased the security that moves the sword.

Preferably, a plurality of the sawtooth blocks are uniformly distributed on the side wall of the edge of the movable knife in the circumferential direction.

Through adopting above-mentioned technical scheme, through sawtooth block circumference evenly distributed on moving the sword, make sawtooth block atress more even for it is more stable in the screen panel to move the sword, has increased the stability of moving the sword.

Preferably, the number of the sawtooth blocks is at least three.

Through adopting above-mentioned technical scheme, be three and above sawtooth block through quantity, make the distribution of sawtooth block denser, make and move the conflict point more than or equal to three points between sword and the joint ring for it is more stable to move the sword, reduces the probability that moves the sword and rock in the screen panel.

Preferably, the sawtooth block is shark fin-shaped, and an inclined plane is arranged on the side wall of the sawtooth block along the rotation direction of the sawtooth block.

Through adopting above-mentioned technical scheme, the sawtooth block receives the air resistance influence and can form the vortex of negative pressure at the afterbody of sawtooth block when rotating to increase the sawtooth block resistance when rotating, and through being shark fin-shaped sawtooth block and along the inclined plane of direction of rotation slope, can be cut before the air current forms the vortex, thereby the windage that the sawtooth block received when having reduced high-speed rotation has reduced the sawtooth block and to moving the influence of sword rotational speed, make move more stable and high-efficient of sword work.

Preferably, a plurality of through grooves penetrate through the movable blade.

Through adopting above-mentioned technical scheme, through running through the logical groove that moves the sword, make the beard that the blade was scraped fall to the fuselage and store in, reduced the probability that the beard is piled up on moving the sword.

Preferably, the through grooves are circumferentially and uniformly distributed on the movable knife.

Through adopting above-mentioned technical scheme, through evenly distributed at the logical groove on moving the sword for the beard blanking is more even, has reduced the probability that appears moving the circumstances that one side beard blanking and opposite side beard pile up on the sword.

Preferably, a knife groove is formed in one side, away from the machine body, of the inner side wall of the mesh enclosure, the knife groove is formed in a mode of surrounding the inner side wall of the mesh enclosure, the diameter of the knife groove is larger than that of the inner side wall of the mesh enclosure, a blade is arranged on the movable blade, an elastic sheet used for stretching the blade is arranged on the blade, and the elastic sheet is fixed to the movable blade.

Through adopting above-mentioned technical scheme, when the user began to scrape the beard, the blade will be contradicted on the inner wall of screen panel, and the blade makes the shell fragment shrink on moving the sword this moment, and blade and sawtooth block are at the sword inslot rotation simultaneously for blade and sawtooth block are difficult to take place the friction with the inboard of safety cover in the rotation process, have reduced the influence of friction to moving the sword rotational speed.

Preferably, the end of the blade far away from the movable blade inclines along the rotation direction of the blade.

By adopting the technical scheme, the end part of the blade far away from the movable blade inclines along the rotation direction of the blade, so that the blade can cut off beards conveniently, and the working efficiency is improved.

Preferably, an electric shaver, including the fuselage, install any one of the above-mentioned tool bit on the fuselage, screen panel threaded connection is on the fuselage, install the rotation motor in the fuselage, the output shaft of rotating the motor is connected on the center pin that moves the tool bit.

Through adopting above-mentioned technical scheme, through installing the tool bit on the fuselage to through rotating the motor to the rotation that moves the sword provides power.

In summary, the present application includes at least one of the following beneficial technical effects:

1. when the movable knife needs to be installed in the mesh enclosure, the movable knife is placed in the mesh enclosure in an inclined mode, then the movable knife is placed in a positive mode, the sawtooth blocks abut against the side wall of the clamping ring, and the movable knife can be installed conveniently and quickly; through sawtooth block butt on the joint ring, make the sword be difficult to follow the screen panel and drop, increased the stability of moving the sword, thereby reduced and moved the sword and drop from the screen panel and cause the probability of injury to the user, increased the security that moves the sword.

2. When the sawtooth blocks rotate, the tail of the sawtooth blocks can form negative pressure vortex under the influence of air resistance, so that the resistance of the sawtooth blocks during rotation is increased, the sawtooth blocks can be cut before the airflow forms vortex through the inclined plane inclined along the rotation direction, the air resistance of the sawtooth blocks during high-speed rotation is reduced, the influence of the sawtooth blocks on the rotating speed of the moving knife is reduced, and the moving knife can work more stably and efficiently.
