Description

Technical Field

[0001] This utility model relates to the field of hair trimmer technology, specifically to a blade-type trimmer head and a hair trimmer. Background Technology

[0002] The blade-and-net trimmer head includes a blade holder, a blade net, and a moving blade. The blade net is fixedly installed on the top of the blade holder, and the moving blade is located at the bottom of the blade net. The moving blade slides back and forth on the blade holder, thus working with the blade net to trim hair.

[0003] The existing clipper head is an inverted U-shape with grooves on the head holder. The clipper head is located within these grooves, with its two outer walls abutting against the groove walls. When the moving blades are in motion, the clipper head vibrates and rubs against the head holder, generating additional noise. Furthermore, a single clipper head results in fewer points of contact between the clipper head and the skin when trimming hair, preventing it from conforming better to the body's curves (such as the chin), leading to poor trimming results. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a blade-and-net type trimmer head, comprising a blade holder and a blade net. The blade holder has a mounting hole at its top, and the blade net is inserted into the mounting hole and connected to the blade holder. The wall of the mounting hole and the outer peripheral wall of the blade net are spaced apart by a clearance. There are two mounting holes spaced apart, and two blade nets are provided, with the two blade nets respectively installed in the two mounting holes.

[0005] Optionally, the distance between the outer wall of the blade mesh and the wall of the corresponding side of the mounting hole is 0.2mm-1mm.

[0006] Optionally, the blade mesh is provided with a plurality of circular entry holes spaced apart.

[0007] Optionally, two anti-splash protrusions are symmetrically provided in the mounting hole and fixedly connected to the cutter head holder. The two anti-splash protrusions are located at both ends of the length of the cutter net. Both the cutter net and the anti-splash protrusions protrude from the mounting hole, and the protruding length of the anti-splash protrusions is greater than the protruding length of the cutter net.

[0008] Optionally, the end of the blade mesh near the splash guard is spaced apart from the splash guard.

[0009] Optionally, the outer peripheral wall of the splash-proof protrusion and the wall of the mounting hole are spaced apart.

[0010] Optionally, the splash-proof bump has a transition arc surface.

[0011] Optionally, the blade-type trimmer head also includes two sets of moving blades, both sets of moving blades being slidably connected to the blade head holder. The two sets of moving blades correspond to the two blade nets respectively for trimming hair. A linkage is slidably provided on the blade head holder, and the linkage is adapted to be connected to the drive component. Both sets of moving blades are connected to the linkage to achieve synchronous sliding.

[0012] Optionally, the linkage is provided with an elastic sheet, the elastic sheet including a base spring sheet and an elastic support foot, the base spring sheet is connected to the linkage and moves synchronously, one side of the elastic support foot is fixedly connected to the base spring sheet, and the other side extends obliquely towards the moving blade assembly to drive the moving blade assembly and the blade net to abut together, and multiple elastic support feet are spaced apart on the base spring sheet, and the multiple elastic support feet abut against two moving blade assemblies respectively.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. When trimming hair, the mounting holes allow the outer side of the blade holder to support the entire trimming head. The two mounting holes increase the distance between the two blades, increasing the contact points with the skin, allowing the trimming head to better conform to the body curve, improving the trimming effect, and ensuring a more even trim.

[0015] 2. After the blade mesh is installed in the mounting hole, there will be a clearance between it and the hole wall, so that the outer wall of the blade mesh does not contact the hole wall, reducing the vibration and friction between the blade mesh and the blade holder when the moving blade moves, thereby reducing the generation of additional noise.

[0016] 3. The clearance design facilitates the insertion of the brush for cleaning, improving the convenience of cleaning the trimmer head;

[0017] 4. The two splash guards can block the short hair generated during the trimming process, making it less likely for the short hair to splash outside the trimmer blades.

[0018] In addition, this utility model provides a hair trimmer, including the blade-and-net type trimmer head as described above.

[0019] Compared to existing technologies, the hair trimmer described in this utility model has the same advantages as the aforementioned blade-type trimmer head, which will not be repeated here. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0026] In the first aspect, this utility model embodiment provides a blade-type trimmer head, referring to... Figure 1 and Figure 2 The blade-and-net trimmer head includes a blade holder 1, a blade net 2, and moving blade assemblies 3. The blade holder 1 has mounting holes 11 at its top. The blade net 2 is inserted into the mounting holes 11 and connected to the blade holder 1. A clearance 12 is provided between the wall of the mounting holes 11 and the outer peripheral wall of the blade net 2. Two mounting holes 11 are provided at intervals. Two blade nets 2 and two moving blade assemblies 3 are provided, each installed in one of the two mounting holes 11. Both moving blade assemblies 3 are slidably connected to the blade holder 1, and each set of moving blade assemblies 3 corresponds to one of the two blades for trimming hair.

[0027] The two mounting holes 11 increase the distance between the two blades 2, increasing the contact points with the skin and allowing the trimmer head to better conform to the body's curves, thus improving the trimming effect. The two blades 2 have the same mating structure with the corresponding mounting holes 11 and the moving blade assembly 3. The following explanation uses the mating of one blade 2 with the blade holder 1 and the moving blade assembly 3 as an example.

[0028] Reference Figure 2 and Figure 3In this embodiment, the preferred blade mesh 2 is an inverted U-shaped mesh, which facilitates connection of both sides of the blade mesh 2 to the blade head holder 1. After the inner walls of both sides of the blade mesh 2 are connected to the blade head holder 1, they will be welded and fixed to the blade head holder 1, thus improving the stability of the connection between the blade mesh 2 and the blade head holder 1. It also prevents the blade mesh 2 from resonating and generating additional noise when the moving blade assembly 3 moves relative to the blade mesh 2. In another embodiment, the blade mesh 2 may not be welded to the blade head holder 1, but rather positioned and snapped together. The top of the blade mesh 2 has multiple circular hair inlets spaced apart, providing a uniform support surface, resulting in a higher skin fit and better fine trimming effect. In another embodiment, the hair inlets can also be elongated holes. The top of the blade mesh 2 protrudes from the mounting hole 11, further improving the skin fit and trimming effect.

[0029] Combination Figure 2 Reference Figure 3 and Figure 4 The clearance 12 between the two opposite outer walls of the blade mesh 2 and the corresponding side wall of the mounting hole 11 is 0.2mm-1mm. In this embodiment, the clearance 12 between the two opposite outer walls of the blade mesh 2 and the corresponding side wall of the mounting hole 11 is preferably 0.34mm. On the one hand, this facilitates the insertion of the brush for cleaning, reducing the long-term adhesion of skin oil and hair residue and the growth of bacteria; on the other hand, it makes the clearance 12 relatively wide, so even if the side wall of the blade mesh 2 resonates, it is not easy to touch the wall of the mounting hole 11, further reducing the additional noise caused by resonance.

[0030] Assuming the two ends of the vertical sidewall of the blade mesh 2 are along its length, anti-splash protrusions 13 are provided at both ends of the blade mesh 2 along its length. Both anti-splash protrusions 13 are located within the same mounting hole 11 and are fixedly connected to the blade head holder 1. The moving blade assembly 3 reciprocates between the two anti-splash protrusions 13. During hair trimming, the two anti-splash protrusions 13 can block the short hair generated during the trimming process, preventing it from easily splashing outside the trimmer head.

[0031] Combination Figure 2 Reference Figure 3 and Figure 4 Specifically, the width of the anti-splash protrusion 13 is greater than the width of the blade mesh 2, and the anti-splash protrusion 13 protrudes beyond the mounting hole 11, with a protruding length greater than that of the blade mesh 2. Therefore, when the trimmer head moves back and forth between the two anti-splash protrusions 13 to trim hair, the hair near the two anti-splash protrusions 13 will be blocked by the anti-splash protrusions 13 after being cut. The outer peripheral wall of the anti-splash protrusion 13 is spaced apart from the hole wall of the mounting hole 11, so that the hair near the anti-splash protrusion 13 can fall through the gap between the anti-splash protrusion 13 and the hole wall of the mounting hole 11 into the special hair collection position inside the trimmer head or hair trimmer; at the same time, it is also convenient to clean the area of ​​the anti-splash protrusion 13.

[0032] Combination Figure 2 Reference Figure 3 and Figure 4 The blade mesh 2 is spaced apart from the splash guard 13, so that the end of the blade mesh 2 does not contact the splash guard 13, thereby reducing the resonance caused by the collision between the blade mesh 2 and the splash guard 13. Multiple edges of the splash guard 13 protruding from the mounting hole 11 are provided with transition arc surfaces. When the splash guard 13 comes into contact with the skin, the transition arc surfaces prevent the splash guard 13 from easily causing scratches to the skin.

[0033] The moving blade assembly 3 is located inside the blade net 2. The moving blade assembly 3 includes a moving blade holder and moving blades. The moving blades are located on the side of the moving blade holder near the opening of the mounting hole 11, and the moving blades are fixedly connected to the moving blade holder. When the moving blade holder drives the moving blades to reciprocate relative to the blade net 2, the moving blades can cut and trim the hairs that enter the pores.

[0034] Combination Figure 2 Reference Figure 3 and Figure 4 A linkage component 14 is slidably mounted on the cutter head holder 1. The linkage component 14 is located on the side of the moving cutter holder away from the moving blade, and the linkage component 14 and the moving cutter holder are arranged at intervals. A linkage column 15 is welded to the side of the linkage component 14 near the moving cutter holder. The side of the moving cutter holder near the drive column has two integrally formed support legs, which are arranged at intervals. The linkage column 15 is inserted between the two support legs. When the linkage component 14 slides relative to the cutter head holder 1, the moving cutter holder slides synchronously with the linkage component 14 under the action of the linkage column 15 and the two support legs. Both moving cutter holders in the two sets of moving cutter groups 3 are inserted and engaged with the linkage column 15, so the two sets of moving cutter groups 3 can move synchronously with the linkage component 14. In addition, the corresponding arrangement of the two cutter nets 2 and the two sets of moving cutter groups 3 means that when one set of moving cutter groups 3 is damaged and needs repair, only the corresponding set of moving cutter groups 3 needs to be replaced, resulting in low maintenance costs.

[0035] A spring plate 16 is mounted on one side of the linkage column 15 of the linkage component 14. The spring plate 16 can drive the moving blade holder to press the moving blade against the blade net 2, improving the hair trimming effect. The spring plate 16 includes a base spring plate 17 and spring support legs 18. Multiple spring support legs 18 are provided, spaced apart and symmetrically arranged on opposite sides of the base spring plate 17. The ends of the multiple spring support legs 18 away from the base spring plate 17 abut against the corresponding moving blade holder to drive the moving blade against the blade net 2. The structure is simple and easy to assemble.

[0036] Combination Figure 2 Reference Figure 3 and Figure 4The elastic support 18 is located on the outer wall of the base spring 17 and is integrally formed with the elastic support 18. The end of the elastic support 18 away from the base spring 17 extends obliquely outward from the base spring 17, thereby giving the elastic support 18 good deformation and recovery ability.

[0037] The base spring piece 17 has multiple positioning holes spaced apart. The linkage member 14 has multiple positioning pins integrally formed on the side near the base spring piece 17. The number of positioning pins is the same as the number of positioning holes and they correspond one-to-one. After the base spring piece 17 is placed on the linkage member 14, the multiple positioning pins are inserted into the positioning holes one-to-one, so that the base spring piece 17 can slide synchronously with the linkage member 14.

[0038] The implementation principle of the blade-and-net type trimmer head in this application embodiment is as follows: When trimming hair, the mounting holes 11 allow the outer side of the blade holder 1 to support the entire trimmer head. The two mounting holes 11 increase the distance between the two blade nets 2, increasing the contact points with the skin, allowing the trimmer head to better conform to the body curve and improve the trimming effect. After the blade nets 2 are installed in the mounting holes 11, there is a clearance gap 12 between them and the hole wall of the mounting holes 11, so that the outer wall of the blade nets 2 does not contact the hole wall of the mounting holes 11, reducing vibration and friction between the blade nets 2 and the blade holder 1 when the moving blade moves. The clearance gap 12 facilitates the insertion of a brush for cleaning, improving the convenience of cleaning the trimmer head.

[0039] Secondly, another embodiment of this utility model provides a hair trimmer, which is equipped with the blade-type trimmer head described in the first aspect, increasing the contact points with the skin, improving the trimming effect, and facilitating cleaning.
