Set up two piece at least stands 3 between net dish 1 and base 2 to make the broach 11 that sets up on net dish 1 outwards extend along the center and be connected fixedly with stand 3 and form into hair passageway 4, can leading-in beard simultaneously between 1 surperficial broach 11 of net dish and two stands 3 like this, compare with traditional circular knife net, increased the increase that hair volume can show during shaving, effectively promoted the benefit of shaving more between the stand 3 of side advances hair passageway 4. Secondly, at least two spaced upright posts 3 are additionally arranged between the net disc 1 and the base 2, long beards cannot enter the net disc 1 under the limitation of the space between the surface comb teeth 11 (when the length of the beards is more than 5mm, the shapes of the beards inevitably have some form changes, most directly show that the beards are curled, the passing sectional area of the beards is relatively increased, the beards cannot enter the circular knife net to finish shaving under the limitation of the space between the comb teeth 11, the existing solution is to additionally increase a pair of clippers on the rotary shaver, the long beards are firstly shaved by the pair of clippers, and then the circular knife net is used for secondary shaving). By arranging at least two upright posts, long beards can enter the net disc 1 through the hair inlet channel 4 between the upright posts 3, so that long and short beards can be shaved at one time without the help of a clipper, the technical problem that the existing circular cutter net cannot shave the long beards is effectively solved, meanwhile, the existing rotary shaver can be omitted, and the production cost is reduced.

For the one-time hair feeding amount of the lifting circular knife net to the maximum degree and the shaving benefit of the lifting circular knife net, the upright posts 3 are provided with a plurality of hair feeding channels 4 at intervals, one ends of the hair feeding channels are annularly arranged and fixed at the edge of the base 2, and one ends of the hair feeding channels are fixed with a plurality of comb teeth 11 which are radially extended and arranged along the center of the net disc 1, so that a plurality of hair feeding channels 4 are formed on the peripheral side wall between the base 2 and the net disc 1. The upright posts 3 are arranged at intervals in a ring shape, and the net disc 1 is oppositely provided with a plurality of comb teeth 11, so that a plurality of hair inlet channels 4 are formed on the surface and the peripheral side wall of the circular knife net at the same time, the one-time hair inlet amount of the circular knife net can be effectively increased, and the shaving benefit is improved; in addition, the weight of the circular knife net is reduced, and meanwhile, the strength of the circular knife net can be enhanced by the aid of the plurality of upright posts 3, and the service life of the circular knife net is guaranteed.

In order to facilitate long beards to smoothly and unimpededly enter the circular knife net through the hair inlet channel 4 between the upright posts 3, the hair inlet amount is increased, the shaving benefit and the universality of the circular knife net are improved, the interval distance between the two adjacent upright posts 3 is greater than the interval distance between the two adjacent comb teeth 11, and each upright post 3 is respectively connected and fixed with the corresponding comb tooth 11, so that the hair inlet channel 4 formed by a plurality of comb teeth 11 is formed above the two adjacent upright posts 3. Set up the distance that is greater than between the broach 11 with the distance between the stand 3, when stand 3 is connected fixedly with the broach 11 that corresponds, the top between the coexistence post 3 just has many open broach 11, the long beard of crimp state just can be unimpededly get into in the circular knife net through the passageway 4 that advances between the stand 3 like this, and many open broach 11 just can separate the root of long beard, conveniently move the cooperation of sword 5 and broach 11 lower extreme face and cut off long beard, when having promoted circular knife net commonality (being long, the equal shaving of short beard can shave), can also increase the one-time volume of advancing of hair of circular knife net, the efficiency of shaving is improved.

For facilitating the introduction of long and short beard, the comb teeth 11 are tapered, and the width L1 of the root part is larger than the width L of the end part₂And arc chamfers are arranged at the end parts of the comb teeth 11; the comb teeth 11 are conical, so that the distance between the end parts of the adjacent comb teeth 11 can be enlarged to the maximum extent, and long beards and short beards can enter the circular knife net more easily; moreover, the comb teeth 11 adopt the conical end parts, so that the separation of the root parts of the beard is more facilitated when the shaver is used, and the beard can be shaved conveniently by the matching of the comb teeth 11 and the movable blade 5; arc chamfers are arranged among the end parts of the comb teeth 11, the upper surface and the side walls, so that the comb teeth 11 can be prevented from stabbing the skin, and the use safety is improved; meanwhile, when the circular cutter mesh is produced and processed, burrs can be eliminated, the grinding process is reduced, and the production cost is reduced.

The distance L between the roots of the two adjacent comb teeth 11₃Not less than 0.2 mm; the distance L between the roots of the adjacent comb teeth 11₃The setting is not less than 0.2mm, which is convenient for leading in beard and shaving. Of course, L may be₃The arrangement is larger, for example, 0.35mm and the like, a larger distance is arranged, and the matching distance between the movable blade 5 and the lower end face of the comb teeth 11 is relatively far when the movable blade is used for rotary shaving, so that the skin is easy to feel stabbing due to hair pulling, and the shaving comfort is affected. And if L₃Setting less than 0.2mm is not favorable for leading in beard and affects the shaving performance of the circular cutter net.

In order to facilitate the introduction of long beard into the circular knife net between the net disk 1 and the base 2, the distance L between the two adjacent upright posts 3₅Is the distance L between the end parts of two adjacent comb teeth 11₄2-5 times of the length of the vertical column 3, and a hair inlet channel 4 with less than 5 open comb teeth 11 is arranged above the adjacent vertical columns 3. The distance L between the adjacent upright posts 3₅Arranged at the end part distance L of the adjacent comb teeth 11₄2-5 times of the total weight of the powder. Because the distance between the two upright posts 3 is larger, the long beard in the curled shape can enter the net disc 1 through the hair inlet channel 4 between the upright posts 3 without obstruction; the distance between the adjacent comb teeth 11 is smaller than the distance between the upright posts 3, so that the comb teeth 11 can separate long beards entering the net disk 1, and simultaneously, the movable blade 5 is matched with the bottom end surfaces of the comb teeth 11 to cut the long beards, and the shaving effect is improved. If the distance between the comb teeth 11 is large, the long beard is likely to be pulled when the long beard is cut by the movable blade 5, and therefore, the interval between the comb teeth 11 is preferably set to 4 times the interval between the

upright posts

3, and 3 open comb teeth 11 are provided above the upright posts 3. Of course, the number of the comb teeth may be 3 or 5, but in terms of use, the larger the number of the comb teeth 11, the smaller the interval between the comb teeth 11, the more the hair-plucking phenomenon can be avoided when cutting the long hair in cooperation with the movable blade 5, but the smaller the number of the comb teeth 11, the longer the hair is, the less the hair is, the longer the hair is, the more the hair is, the less the hair is, the more the hair is, the shaving effect is affected.

In order to improve the strength of the surface of the net disk 1 and the comb teeth 11 and the positioning of the circular knife net during installation, a positioning disk 12 is arranged at the center of the net disk 1, and a positioning shaft 13 is arranged on the lower end face of the positioning disk 12; the comb teeth 11 radially extend outwards from the edge of the positioning disc 12; a reinforcing ring 14 is arranged outside the positioning disc 12 to form an open pore 15 and a closed pore 16 on the surface of the mesh disc 1; arc transition angles are respectively arranged at the joints of the peripheral side walls of the reinforcing rings 14 and the comb teeth 11. Through set up positioning disk 12 and beaded finish 14 on net dish 1 surface and make net dish 1 surface form the closed pore 16 that leads of open pore 15, short beard then accessible open pore 15 and closed pore 16 that leads gets into in the net dish 1 during the use, long beard then accessible sets up 3 intervals of stand between net dish 1 and base 2 and open pore 15 that leads and gets into in the net dish 1, convenient long, when short beard is pruned, can also utilize positioning disk 12 and beaded finish 14 to improve the intensity of net dish 1 surface and broach 11, avoid net dish 1 surface and broach 11 to warp, guarantee the life of net dish 1 and broach 11. And set up the locating shaft 13 in the bottom end of the locating disc 12, when the circular knife net assembles, then can utilize locating shaft 13 to carry out the accurate positioning, promote the packaging efficiency.

In order to ensure the use strength of the circular knife net and facilitate the production and processing of the circular knife net, each upright post 3 is perpendicular to the base 2 and the net disc 1, one end of each upright post 3 is connected with the annular side wall 17, the other end of each upright post is connected with the corresponding comb teeth 11, and the base 2, the annular side wall 17 and the upright posts 3 are connected with the net disc 1 into a whole. The upright posts 3 are perpendicular to the net disc 1 and the base 2, so that the production and the processing are easy, and if the net disc 1 and the base 2 are of an integrated structure, the circular cutter net can be integrally formed through processes of stamping, bending or etching and the like. If the net plate 1 and the base 2 adopt a split structure, the upright post 3 and the base 2 are formed into a whole through processes of stamping, bending and the like, and then the comb teeth 11 on the net plate 1 and the upright post 3 are fixed into a whole through modes of welding, bonding and the like. In order to improve the strength of the circular knife net, the annular side wall 17 is arranged on the base 2, one end of each upright post 3 is fixedly connected with the annular side wall 17, the area of the hair inlet channel 4 between the two upright posts 3 and the length of each upright post 3 are relatively reduced by increasing the annular side wall 17, the hair inlet channel 4 can be formed on the peripheral side walls of the net disc 1 and the base 2 while the strength of the circular knife net is ensured, the hair inlet efficiency and the universality of the circular knife net are improved, and the circular knife net is suitable for long and short beard trimming.

As shown in fig. 3 to 6, compared with the technical scheme of the upright column 3 perpendicular to the net disk 1 and the base 2, the applicant also provides a circular knife net scheme of the inclined upright column 3, the circular knife net adopting the scheme is more convenient for catching beard when in use, and the technical scheme is that the annular side wall 17 inclined to the base 2 and the net disk 1 is arranged between the base 2 and the net disk 1, and the inclination angle & of the annular side wall 17₁Setting to satisfy 90 degrees >₁The relation is more than 0 degrees; one end of each upright post 3 is connected with the annular side wall 17, the other end is connected with the corresponding comb teeth 11, and the base 2, the annular side wall 17 and the net disk 1 are of an integral structure. By adding between the net disk 1 and the chassisThe inclined annular side wall 17 is arranged, one end of each upright post 3 is fixedly connected with the annular side wall 17, the other end of each upright post 3 is fixed with the end part of the corresponding comb tooth 11 on the net disc 1, so that the annular side wall 17 and the lower end of each upright post 3 are folded towards the inner side of the base 2 to form an inclined shape, and by adopting the structure, the end part of the comb tooth 11 on the surface of the net disc 1 is more protruded, so that beards are easier to capture and separate when in use, and can quickly enter the net disc 1 through the hair inlet channel 4 between the two upright posts 3, thereby improving the shaving efficiency; the inclined angle of the annular side wall 17 and each upright post 3 is less by taking the upper plane of the base 2 as a horizontal reference₁The angle is set to be greater than 0 ° and less than 90 °, preferably 75 °. From the aspect of beard catching performance, the inclination angle of the annular side wall 17 and each upright post 3 is less₁The smaller the size, the more the end parts of the comb teeth 11 protrude, and the opposite side is easier to capture and separate beards, so that the beards can be quickly guided into the net disk 1, and the shaving benefit is improved. However, if the angle of inclination is too small, for example, 5 ° or 15 °, although the end of the comb teeth 11 on the net disk 1 protrudes more, and thus hairs are easier to be caught, the distance between the net disk 1 and the base 2 is correspondingly reduced, which affects the hair feeding efficiency of the hair feeding channel 4 between the upright posts 3 and relatively reduces the diameter of the opening of the base 2, thereby being unfavorable for the installation and rotary shaving of the movable blade 5. Therefore, the preferred angle of inclination &ofthe annular side wall 17 and the column 3₁At the angle of 35-80 DEG, the specific angle of inclination₁The settings can be customized according to actual needs or customer requirements.

In the actual production process, the base 2, the annular side wall 17 and each upright post 3 are of an integral structure, and are formed by stamping and bending, and the net disc 1 is an independent structure and is integrally connected by welding or bonding. Therefore, the production, processing and assembly benefits can be effectively improved. Of course, the net disk 1, the base 2, the annular side wall 17 and the columns 3 may be formed by an integral structure through stamping, bending or etching processes, but the integral structure makes the production process complicated and the production efficiency low, so that the preferred embodiment is that the net disk 1 and the base 2 are of a split structure.

As shown in fig. 7 to 16, the present application further provides a blade set including the circular blade net and the movable blade 5 attached to the inner end surface of the circular blade net. Compared with the traditional circular knife net, the blade group of the circular knife net with the upright posts 3 arranged on the side wall has the advantages that the hair feeding channels 4 between the upright posts 3 on the side surface are increased, the hair feeding amount can be obviously increased during shaving, long and short beards can be shaved at one time without the help of a clipper, the shaving benefit is improved, the technical problem that the existing circular knife net cannot shave the long beards is effectively solved, meanwhile, the external clipper of the existing rotary shaver can be omitted, and the production cost is reduced.

In order to facilitate shaving of long and short beards and improve shaving benefits of the blade set, the movable blade 5 comprises a movable blade holder 51, a trimming blade 52 and a shaving blade 53, the shaving blade 53 is sleeved outside the movable blade holder 51, the blade edge of the shaving blade 53 is attached to the lower end face of the closed guide hole 16 in the circular cutting net, the trimming blade 52 is sleeved outside the shaving blade 53 and fixed with the movable blade holder 51, and the blade edge of the trimming blade 52 is attached to the lower end face of the open guide hole 15 in the circular cutting net. Because the reinforcing ring 14 is arranged on the circular knife net, the circular knife net forms a closed guide pore 16 and an open guide pore 15, the closed guide pore 16 is used for trimming short hairs or beards, the open guide pore 15 is used for trimming long hairs or beards, so that the long hairs or the short hairs or the beards can be trimmed conveniently, the trimming blades 52 are correspondingly arranged into two groups and are fixed on the head seat of the movable knife 5 in a layer sleeve mode, one group is attached to the lower end face of the closed guide pore 16, the other group is attached to the bottom end face of the open guide pore 15, therefore, when the circular knife is used, hairs with different shapes or lengths can enter different guide pores, the movable knife seat 51 can synchronously drive the trimming blades 52 and the shaver blade 53 to rotate along the bottom end faces of the closed guide pore 16 and the open guide pore 15 respectively and are matched with the closed guide pore 16 and the open guide pore 15 for trimming synchronously, the shaving benefit is improved while the primary hair feeding amount is effectively improved.

In order to improve the trimming benefit of the trimming blade 52, the trimming blade 52 comprises at least one trimming cutter tooth 521, and at least one side of the trimming cutter tooth 521, which is in the same direction as the rotation direction of the trimming blade 52, is provided with a cutting edge, and the cutting edge is attached to the lower end surface of the open pore 15 on the circular knife net; the tail end of the trimmer tooth 521 is provided with a blade bracket 522 which is perpendicular to the trimmer tooth 521, the other end of the blade bracket 522 is fixed with the blade base 2, and the blade base 2 is detachably and fixedly connected with the movable blade base 51. Because the trimming blade 52 is rotated, and a cutting edge in the same direction as the rotation direction is provided on at least one of the trimming teeth 521 of the trimming blade 52, when in use, the cutting edge can be attached to the bottom end surface of the open hair guide hole 15 on the circular blade net to complete the trimming of hair or beard. Of course, the cutting edges may be provided at both ends of the cutter tooth 521, but since the cutting blade 52 is rotated, the cutting edge provided at one side of the cutter tooth 521 in the rotating direction satisfies the cutting requirement of the hair or beard, and thus, the cutting edge provided at one side of the cutter tooth 521 is a preferred embodiment. In order to avoid the interference of the trimming blade 52 with the shaving blade 53, the inner end of the trimming tooth 521 is connected with the blade holder 522 to form a vertical shape with the outward-facing cutting tooth, and the other end of the blade holder 522 is fixed with the blade base 2, so that when the trimming blade 52 is sleeved on the movable blade holder 51, the trimming tooth 521 and the shaving blade 53 are separated from each other and do not interfere with each other, and the shaving performance of the trimming blade 52 and the shaving blade 53 is effectively ensured.
