Detailed Description
The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.
In an embodiment, as shown in fig. 1 to 10, a nose hair trimmer moving blade, the whole moving blade is preferably manufactured integrally and made of metal and steel, and specifically includes a vertical plane-shaped base supporting portion 1, i.e., a flat sheet-shaped structure, a blade body connecting portion 2 protruding upward from the base supporting portion 1 is integrally connected to the base supporting portion 1, the blade body connecting portion 2 is also preferably plane-shaped, the blade body connecting portion 2 is integrally connected to the base supporting portion 1, front and rear blade surfaces thereof are preferably coplanar with front and rear blade surfaces of the base supporting portion 1, the blade body connecting portion 2 is located at a left position or a right position on an upper side of the base supporting portion 1, the blade body connecting portion 2 has an upward extending strip-shaped shape, and further, a top blade body 21 and a side blade body 22 are integrally connected to the blade body connecting portion 2, the top of the top cutter body 21 is provided with a top cutting edge 210, the side of the side cutter body 22 is provided with a side cutting edge 220, and the top cutting edge 210 is preferably in a flat or nearly flat state, so that the included angle between the top cutting edge 210 and the horizontal plane is smaller than 30 degrees, preferably between 0 and 30 degrees and as flat as possible, mainly for better shearing the vibrissa with more components in the axial direction, namely better shearing the vibrissa which is more parallel to the cutter along the nasal cavity wall and is clustered outwards; the side blades 220 are preferably in a state of being approximately upright, so the angle between the side blades 220 and the horizontal plane is preferably greater than 50 degrees, and is preferably between 50 and 90 degrees, and is preferably selected to be between 60 and 80 degrees, but in this embodiment, the side blades 220 are not selected to be perpendicular to the horizontal plane, as will be further described below, because in this embodiment, the top blade 210 and the side blades 220 are specially designed, as follows, the top blade 210 and the side blades 220 are both inclined to the base support portion 1 and are positioned in the front region of the base support portion 1 or in the rear region of the base support portion 1, the base support portion 1 is in an upright state, and the front and rear blade surfaces thereof are vertical surfaces, the front and rear blade surfaces of the base support portion 1 are parallel, taking the front surface of the base support portion 1 as an example, the side blades 220 are inclined to the front side panel of the base support portion 1, and the vertical line, or the vertical line perpendicular to the horizontal plane, is on the vertical plane, that is, the vertical line exists on the front side panel of the base support portion 1, so the side blades 220 are not vertical to the vertical line and the horizontal plane, and similarly, the top blade 210 is not vertical to the horizontal plane, but the top blade 210 is parallel to the horizontal plane as much as possible, and the side blades 220 need a certain standing state but are not vertical as much as possible, so that the side blades can be better matched with the fixed blade on the side, which will be further discussed later. In general, the feature that "the top blade 210 and the side blade 220 are both inclined to the basic supporting portion 1 and located at the same front region of the basic supporting portion 1 or at the same rear region of the basic supporting portion 1" has a very large meaning, on the one hand, the inclined state is to better match with the fixed blade and to cut with a better cutting angle with the whisker feeding structure, rather than the parallel state, so as to achieve a better oblique cutting state, and to better utilize the driving force to make the effective cutting time longer, on the other hand, the effect of the double blades cutting in the same direction and synchronously is better, that is, to ensure that both blades are in the same cutting direction, for example, both clockwise cutting direction or both counterclockwise cutting direction, when cutting is selected, on the other hand, two cutter bodies can reduce radial dimension through the mode of bending and can promote compact structure nature to a certain extent, also have certain help to structural strength and stability. The embodiment provides a scheme, which specifically comprises:
the cutter body connecting part 2 is integrally connected to the left side of the upper side of the basic supporting part 1, the cutter body connecting part 2 is located at the upper left corner of the basic supporting part 1, the side cutter body 22 is integrally connected to the left side of the cutter body connecting part 2, the top cutter body 21 is integrally connected to the upper side of the cutter body connecting part 2, the side cutter body 22 and the top cutter body 21 are also located at the upper left corner of the basic supporting part 1, the top cutting edge 210 and the side cutting edge 220 are inclined towards the front side of the basic supporting part 1, and therefore the blade rotates clockwise to cut. The entire movable blade is vertically rotated around a vertical axis, so that a rotating body is formed, the side blade 22 is sheared at the lateral periphery of the rotating body, the side blade 220 is a cutting edge at the left side of the side blade 22, and the top blade 210 is at the top of the top blade 21. In order to match the deflection of the cutting edge, the side blade body 22 and the top blade body 21 are inclined to the base support portion 1 and, of course, to the blade body connecting portion 2, and the side blade body 22 and the top blade body 21 are deflected forward and connected to the blade body connecting portion 2 to form an inclined state, and such deflection connection is achieved by bending. Here, the top blade body 21 is integrally extended rightward, the top blade body 21 and the blade body connecting portion 2 are L-shaped, and the degree of deflection between the side blade bodies 22 and the top blade body 21 themselves and the blade body connecting portion 2, or the degree of deflection between the front and rear vertical surfaces of the blade body connecting portion 2, is controlled to be as small as possible, because the degree of bending by the bending process is not so large, and it is preferable to be controlled to be substantially within 30 degrees of deflection. Accordingly, the inclined state of the top blade 210 and the base support portion 1 is formed by bending the top blade body 21 and the blade body connecting portion 2, and the inclined state of the side blade 220 and the base support portion 1 is formed by bending the side blade body 22 and the blade body connecting portion 2. Since the degree of deflection is not high, the front and rear sides of the side blade body 22 and the top blade body 21 are still biased to the standing state, and the blade body or the entire blade has a certain thickness, so the cutting edge is disposed in the edges of the front and rear sides of the blade body, and it is particularly preferable that the top cutting edge 210 is the edge of the top blade body 21 on the bent side, and the side cutting edge 220 is the edge of the side blade body 22 on the bent side. In this context, the angle of bending the top blade body 21 to deflect from the base support portion 1 is 0 to 30 degrees, that is, the angle of any one of the front and rear sides of the top blade body 21 to any one of the front and rear sides of the base support portion 1 is 0 to 30 degrees, and the angle of bending the side blade body 22 to deflect from the base support portion 1 is 0 to 30 degrees, so that the inclination angle B formed by the inclination of the top blade 210 to the base support portion 1 is 0 to 30 degrees, and the inclination angle a formed by the inclination of the side blade 220 to the base support portion 1 is 0 to 30 degrees, and further preferably, the inclination angle a formed by the inclination of the side blade 220 to the base support portion 1 is larger than the inclination angle B formed by the inclination of the top blade 210 to the base support portion 1, for example, by 5 to 15 degrees, so that the front side bending structure can be optimized, it is easier to prefer that a part of the side blade 220 is located in front of the top blade 210, which means that, although all the blades are cut forward synchronously, the side blade 220 of the whole blade is cut for a section first in the clockwise rotation process, and then the top blade 210 is also cut, so that the stress time point of the blade is optimized, a cutting process with a continuous time period is formed, the stress effect of the blade is better, the problem of insufficient pressure caused by cutting more nose hairs at the same time, the cutting is not continuous, and even the problem of jamming or nose hair curling is caused, the blade is damaged, and the use is more uncomfortable for people.
Preferably, the top cutter body 21 and the cutter body connecting part 2 are connected in a bending way through a top bending reinforcing rib x1 which is obliquely bent right and downward, the top bending reinforcing rib x1 can be a reinforcing rib which extends obliquely and is arched forwards, the included angle between the reinforcing rib and the horizontal plane is controlled to be 40-80 degrees, preferably about 60 degrees, and the reinforcing rib is a concave reinforcing rib when viewed from the back, because the reinforcing rib is in connection transition, the strength is improved through self arc-shaped bending; the side blade body 22 and the blade body connecting portion 2 are connected by being bent by a single straight side bending bead x2 in the vertical direction, and the side bending bead x2 is also preferably a curved bead, so that the strength at the bending position is improved. Further, an arc-shaped transition groove x3 with an opening facing the upper left corner is formed from the upper left corner of the top cutter body 21 along the top of the top bending reinforcing rib x1, the upper left corner of the cutter body connecting part 2, the top of the side bending reinforcing rib x2 and the top of the side cutter body 22, so that the structure is optimized and the structural stability is improved.
The basic supporting portion 1 is optimized, specifically, the basic supporting portion 1 includes a first installation segment 11 integrally connected with the bottom of the cutter body connecting portion 2, a second installation segment 12 located below the first installation segment 11, and an intermediate installation segment 13 integrally connected between the first installation segment 11 and the second installation segment 12, the first installation segment 11 and the second installation segment 12 may have the same or similar shape and size, for example, both adopt a flat square-shaped structure, the whole body looks rectangular, and the corner positions adopt fillet transition as much as possible. Further, the cutter body connecting portion 2 and the intermediate mounting segment 13 are located on the left side of the base supporting portion 1 or on the right side of the base supporting portion 1, and referring to the above-mentioned embodiment, the cutter body connecting portion 2 and the intermediate mounting segment 13 are preferably located on the left side of the base supporting portion 1, that is, on the left half of the base supporting portion 1 and located near the left side, it can be understood that the center between the left and right sides of the base supporting portion 1 is located on the left side, and the purpose of designing in this way is to mount two centrosymmetric movable blades on the cutter head, and of course, the structure is more optimized, so as to ensure the stability of the left structure, and to make the cutter body connecting portion 2 and the intermediate mounting segment 13 align up and down as much as possible without shifting left and right as much as possible. The middle mounting segment 13 is close to a rectangular structure, and the corner can be connected with other parts by adopting fillet transition. Furthermore, the middle mounting segment 13 is integrally connected with a mounting boss 130 facing to the right or left, if the middle mounting segment 13 is arranged on the left, the mounting boss 130 facing to the right is connected, this is for being mounted on the cutter head, for being used for mounting a spring, because the same two blades are adopted, after one is placed, because the other is centrosymmetric, two opposite mounting bosses 130 are formed, the spring is mounted between the two opposite mounting bosses 130, which will be explained later, and of course, the spring design also exists in the prior art.
In order to mount the movable blade, it is necessary to form a first mounting positioning hole 110 penetrating in the front-rear direction and extending in the left-right direction in the first mounting segment 11, and form a second mounting positioning hole 120 penetrating in the front-rear direction and extending in the left-right direction in the second mounting segment 12. The opening between the first mounting segment 11 and the second mounting segment 12 is a positioning hole, and the first mounting positioning hole 110 and the second mounting positioning hole 120 are strip-shaped holes extending left and right.
Further, a transverse limiting boss 1100 which is arched forwards or backwards is integrally connected with the first installation section 11 at the position of the first installation positioning hole 110 at the side opposite to the installation boss 130, the lateral position-limiting projection 1100 is located at the same position as the top blade 210 and the side blade 220 at the front region of the base supporting part 1 or at the same position as the rear region of the base supporting part 1, the design is also used for mounting the movable blade, mainly for mounting the limiting, such as the movable blade provided by the scheme, the top blade 210 and the side blade 220 are in the front region, and the lateral limit projection 1100 is thus arched forward and in the front region, because the transverse limiting boss 1100 can also be bent by stamping and the like, the structures formed by the bending process are all on the same side, and the production is more convenient and reliable. Of course, it is also possible that the lateral limiting protrusion 1100, the top blade 210 and the side blades 220 are located at different side areas in front and at the back of the base supporting portion 1, so that both sides of the base supporting portion 1 have a bent structure, which is not easy to produce and transport and increases the cost. The lateral limiting projection 1100 is preferably in a cambered arched structure, and the moving blade of the same one of the above-mentioned embodiments is formed on the right side of the first mounting hole 110 on the first mounting segment 11 because the mounting protrusion 130 is on the left side.
Similarly, the second mounting segment 12 may be provided with the same lateral limiting projection 1100, that is, the second mounting segment 12 is integrally connected with the lateral limiting projection 1100 which is arched forward or backward at a position on the opposite side of the second mounting positioning hole 120 from the mounting boss 130.
Further, the bottom of the side blade body 22 is integrally connected with an upper balance fin 31 which is located below the bottom and has a side portion contacting with the inner side wall of the fixed blade, the upper balance fin 31 can be bent together with the side blade body 22, the right side of the upper balance fin 31 is also connected with the blade body connecting portion 2 and is integrally connected through the side bending reinforcing rib x2, namely, the side bending reinforcing rib x2 extends up and down to be used as a bending and integrally connecting and transiting part of the side blade body 22 and the upper balance fin 31 and the blade body connecting portion 2, the left side edge portion of the upper balance fin 31 extends and inclines towards the left lower side, namely, the lateral dimension towards the lower side is preferably gradually small, and the design is mainly used for matching with the fixed blade. Furthermore, the side portion of the second mounting segment 12 is integrally connected with a lower balance wing 32 which is located below the upper balance wing 31 and is also used for contacting with the inner side wall of the fixed cutter, the lower balance wing 32 is located at the left side portion of the second mounting segment 12, but the lower balance wing 32 is flat with the second mounting segment 12, and the front surface and the rear surface are coplanar, that is, the two are integrally of a planar structure, and the lower balance wing 32 is also used for matching with the fixed cutter. The upper and lower balance fins are in contact with the inner side wall of the fixed knife, so that a little friction force exists in the rotating process of the movable knife blade, but the surface friction coefficients of the upper and lower balance fins are small as much as possible, so that the friction loss can be reduced.
The directions of the movable blades are observed from the rear side view angle of one movable blade, the blade is a structure that two cutting edges are arranged at the left side and face forwards, two identical blades are needed in the blade assembly process, but the other blade is arranged symmetrically with the first center when being arranged, so that the other movable blade is a structure that two cutting edges are arranged at the right side and face backwards in the same view angle, and the specific figure also shows that the blade assembly is explained.
