Abstract

The utility model relates to a rotary shaver, a trimming cutter head and a trimming tool, which are characterized in that at least one movable cutter tooth is provided with a front angle and a rear angle, the vertical distance T between the front angle and the rear angle is smaller than the length of a hair guiding groove in a static cutter, so that an outer rotating track of the front angle and an inner rotating track of the rear angle are both positioned in the hair guiding groove of the static cutter, and a first included angle S1 is formed between a movable cutter edge and a static cutter edge in an inclined manner when the front angle approaches any hair guiding groove in any static cutter. The utility model has the beneficial effects that through mutually adjusting the front angle and the rear angle of the movable cutter tooth, when the front angle of the movable cutter tooth contacts the static blade of the static cutter tooth, a closed state is formed between the front angle of the movable cutter tooth and the static blade, at the moment, even if part of hairs such as beard to be sheared are extruded by the passive blade and the static blade, the trimming areas of the movable blade and the static blade can be slid out from the openings of the rear angle and the static blade below, thereby preventing the phenomenon of hair pulling from happening at the moment of moving the trimming tool and improving the use comfort of the trimming tool.

Description

Rotary shaver, trimming cutter head and trimming tool Technical Field The utility model relates to a hair trimming device, in particular to a rotary shaver, a trimming cutter head and a trimming tool, which are mainly applied to the field of personal care tools such as shavers, shavers and the like. Background The existing rotary pruning tool bit is shown in the attached figure 1 of the specification, and comprises a circular static tool (1) and a movable tool (2), wherein a plurality of static tool teeth (11) which are arranged at intervals and are in annular arrays are arranged on the static tool (1), a hair guide groove (12) is formed between every two adjacent static tool teeth (11), a plurality of movable tool teeth (21) which are in annular arrays are arranged on the movable tool (2), and a front angle (211) and a rear angle (212) are respectively formed on each movable tool tooth (21). In order to facilitate the trimming of beard and other hairs, a movable blade (211) in the conventional movable blade tooth (21) forms an inclined angle which is inclined outwards relative to a static blade (111) in the static blade tooth (11), so that a front angle (212) of the movable blade tooth (21) is positioned below the movable blade tooth (21), a rear angle (213) is positioned above the movable blade tooth (21), and the front angle (212) and the rear angle (213) are connected to form the inclined movable blade (211). When cutting hairs such as beard, the front angle (212) of the movable cutter tooth (21) approaches the static cutter blade (11) before the rear angle (213) so that an opening state is formed between the rear angle (213) and the static cutter blade (11), and thus the hairs (23) such as beard to be cut can enter between the movable cutter blade (21) and the static cutter blade (11) at any time, as shown in an enlarged view in fig. 1. When the user holds the pruning tool to shave, the pruning tool is basically frequently moved along the skin surface and is influenced by the fixed state of the static blade (11), when the front angle (212) of the movable blade teeth (21) approaches to the static blade (11), hairs (23) such as beards to be cut are driven towards the static blade (1), and part of hairs (23) such as beards to be cut cannot move at the moment when the movable blade (211) is pressed by the static blade (11), especially cannot move downwards due to the limitation of the front angle (212), and at the moment, if the user holds the pruning tool to move upwards, the hairs (23) such as beards to be cut extruded by the passive blade (21) and the static blade (11) near the front angle (212) can form a hair pulling phenomenon under the condition that the hairs (23) are not moved downwards, so that the skin of the user generates dragging pain, as shown in a simulation diagram of fig. 2a and fig. 2b, the using comfort of the pruning tool is reduced. Disclosure of utility model In order to solve the technical problems, the utility model provides the rotary shaver, the trimming cutter head and the trimming tool, wherein the front angle of the movable cutter blade is closed with the static cutter blade when approaching to the static cutter blade by changing the shape of the movable cutter blade of each movable cutter blade, so that hairs such as beard and the like are prevented from entering the trimming areas of the movable cutter blade and the static cutter blade in the trimming process, and the user can not generate a napping phenomenon no matter how the user holds the trimming tool to move upwards (or forwards) along the skin, and the use comfort of the trimming tool is improved. The rotary shaver comprises a shaver body, a plurality of rotary cutting movable cutter teeth are arranged on the shaver body, at least one movable cutter tooth is provided with a front angle and a rear angle, when the movable cutter tooth rotates along the shaver, the front angle is provided with an outer rotation track, the rear angle is provided with an inner rotation track, the outer rotation track diameter of the front angle is smaller than the inner rotation track of the rear angle, the vertical distance T between the front angle and the rear angle is smaller than the length of a hair guide groove in the shaver, the outer rotation track of the front angle and the inner rotation track of the rear angle are both positioned in the hair guide groove of the shaver, the front angle and the rear angle are connected to form an inclined movable cutter edge, and when the front angle approaches any hair guide groove in the shaver, the movable cutter edge and the static cutter edge of the adjacent hair guide groove form a first included angle S1 in an inclined manner. Preferably, when each movable cutter tooth contacts the static cutter tooth at the front angle, the first included angle S1 between the movable cutter blade and the static cutter blade is more than or equal to 5 degrees and less than or equal to 30 degrees.
