Description

Hair trimming device with layered effect

technical field

The utility model relates to a hair cutting scissors, in particular to a hair trimming device capable of preventing discomfort caused by hair being pulled during cutting and having a layered effect after cutting. the

Background technique

During a haircut, usually by means of hairdressing tools such as special scissors, an electric hair clipper or a hair trimmer of a clip-cut type up and down, the barber trims according to the hairstyle design. the

General haircutting scissors, in addition to sharper blades, in order to allow hairdressers to operate quickly, so the length of the contact surface of the blades during use will not be too long, and relatively unable to cut hair volume, resulting in more time-consuming for hairdressers strenuous. Electric hair clippers use electric motors combined with cross-operating blades to quickly cut hair. Most of them are used to trim flat heads or to perform a large amount of trimming. Due to the fast trimming speed, it is usually difficult to control accurately when dealing with details, and once a mistake is made After that, it cannot be saved. Therefore, most barbers use the two in parallel. However, when the above-mentioned two kinds of hairdressing tools are in use, the hairdresser grabs or combs the amount of hair to be cut and then cuts it. The operation is a way of extruding and cutting the hair in one direction, which makes the incision form a slope and unevenness. Therefore, after the hair is cut, consumers usually feel that the hair tip is not smooth and has a burr feeling. the

And this kind of hair trimmer is made of a pair of splints, the end edge of this pair of splints is provided with cutting edge respectively, and this pair of splints respectively has an elastic element, when this pair of splints are combined, the pair of elastic elements is opposite and provides the required flexibility. When in use, the hair is placed between the two cutting blades, and an external force is directly applied to the pair of splints, so that the two cutting blades are combined and cut. Cut off vertically so that the incision forms a flat plane, so the hair tip feels smooth and burr-free. But this kind of hair trimmer can't carry out good control to the cutting position, length and layer thickness etc. of hair, therefore, the hair tip of the hair after trimming is too neat and lacks aesthetics. the

For this reason, the designer of the utility model once applied for the No. M349832 "hair trimmer" in Taiwan, China. This hair trimmer includes a pair of clamps, including a clamp with upper and lower pressure plates. Elastic element; at least two cutting units respectively assembled on the edge of the upper and lower platen, each cutting unit has a corresponding cutting part, and the end edge of each cutting part has a plurality of sipes of different depths; And at least two combing units respectively combined with the upper and lower platens and corresponding to the outside of each cutting unit, which respectively include combs corresponding to each other and parallel to the cutting part, and the end edges of each comb have a plurality of different Deep and shallow comb grooves. In this way, the cooperation of the clamp, the cutting unit and the combing unit can be used to carry out the thinning action when trimming the hair, so that the hair can achieve the effect of layering and aesthetics after trimming. In actual use, since the plurality of cutting parts will first contact and clamp the fixed hair, and then the pair of combing units will clamp and bend the hair. Since there will be differences in length when the hair is bent, a sense of hierarchy can be formed. , but it will pull the root of the hair and cause discomfort during operation, so it is necessary to improve it. the

Please refer to Fig. 7, Fig. 8, Fig. 9 and Fig. 10, which are schematic diagrams of the hair bending state when the first protective cover and the second protective cover of different stages are used in the preferred embodiment of the present invention, and the first and second protective covers through each stage Comparison of the hair length after shearing of the first cover and the second cover. Please also refer to Fig. 1A, as shown in the figure, the hair trimming device 1 with a layered effect of the present utility model uses different numbers of first hair combs 131 and the second hair combs 161 according to the first combs 131 and 161. Cover 13 and this second protective cover 16, the length of this hair 2 that cuts out is also different to some extent. As shown in Figure 7, it is an implementation of the first hair comb 131 and the second hair comb 161 of the first-order type. It bends the hair 2 once, and it is also subjected to the plurality of first hair combs of different depths. The comb groove 1312 and the plurality of second comb grooves 1612 have different degrees of bending of the hair, so the hair will naturally have different layers of length after cutting. As shown in Figure 8, it is the embodiment of the first hair comb 131 and the second hair comb 161 of the second-order type. 16. Make the hair 2 bend through the plurality of first comb slots 1312 and the plurality of second comb slots 1612 of different depths for two consecutive times, so that the bending range of the hair 2 is larger, compared with a The difference in length of the hair 2 cut out by the first-order type is more obvious and larger in the second-order type. As shown in Figure 9, it is the embodiment of the plurality of first hair combs 13 and the plurality of second hair combs 16 of the three-stage type. Similarly, the hair 2 is bent for three consecutive times, and the bending range larger than the second-order form. Therefore, it can be seen from FIG. 10 that when the hair 2 undergoes different stages of clipping, the difference in length is more obvious, and the degree of difference is third order>second order>first order, that is, the layering is more distinct. the
