[0011] In some embodiments, the blade holder has a blade engaging slot for engaging with the first holder.

[0012] In some embodiments, the hair-flattening component has a plurality of sheet-like adhesive strips arranged side by side, and any one of the sheet-like adhesive strips is arranged parallel to the shaving blade; the end face of the sheet-like adhesive strip protrudes beyond the cutting edge of the blade in the blade holder.

[0013] In some embodiments, the frame body has mounting guide posts at both ends of the central section, and the blade holder has mounting guide grooves at both ends. When the blade body is placed in the central section of the frame body, the mounting guide posts are engaged in the mounting guide grooves.

[0014] In some embodiments, the peripheral surface of the tool holder is also provided with a lubricant.

[0015] A second aspect of the present invention relates to a razor having any of the aforementioned blades.

[0016] A third aspect of the present invention relates to a blade head and body, comprising a blade holder, wherein the functional surfaces of the blade holder are provided with a blade mounting groove and a bristle flattening member arranged side by side, and the blade mounting groove is provided with the blade mounting member; wherein,

[0017] The blade holder has 6 blade slots, each containing a shaving blade, which is positioned toward the hair-flattening component. The distance between the hair-flattening component and the first blade is 0.5–1.5 mm, and no hair guide is provided.

[0018] In some embodiments, the substrate surface of the hair-flattening component has a plurality of flexible sheet-like adhesive strips arranged in parallel, and any one of the flexible sheet-like adhesive strips is arranged parallel to the shaving blade; the end faces of the plurality of flexible sheet-like adhesive strips all protrude beyond the cutting edges of the six blades in the blade holder.

[0019] The beneficial effects of this invention are:

[0020] Even without the hair guide, it maintains good guiding performance and also increases the number of blades from 5 to 6. The span between adjacent blades limits the overlap within an appropriate range, improving the razor's washability and shaving comfort. Attached Figure Description

Detailed Implementation

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] Blade tip, such as Figure 1-5 As shown, including

[0028] The cutter head holder 100 has a central section 110, and the inner wall of the central section 110 is provided with a cutter body retainer 130; the central section 110 is used to set the cutter body 200, and the cutter head holder 100 covers and surrounds the periphery of the cutter body 200.

[0029] The blade body 200 is engaged in the through portion 110 of the frame body by abutting against the blade body engaging member 130. The blade body 200 has a blade holder 210, and the functional surfaces of the blade holder 210 are provided with blade mounting slots and hair-feathering members 241 arranged side by side. The blade mounting slots are provided with blade mounting members 211.

[0030] The blade holder 211 has six blade slots, each containing a shaving blade 212, which is positioned towards the hair-flattening member 241. The blade body of this invention employs six layers of blades, providing a better shaving effect compared to the commonly used five-layer blade body.

[0031] The cutter head holder 100 can be used to set up other auxiliary components such as the lubrication component 300.

[0032] like Figure 3 As shown, the blade body locking member 130 includes a first locking member 131 and a second locking member 132 located on the inner walls of both sides of the through portion 110 of the frame. The first locking member 131 includes at least a first locking member protrusion and a second locking member protrusion. The first locking member 131 is used to engage with the blade body locking member 130, and the second locking member 132 is used to engage one side of the blade holder 210. The second locking member 132 is a protrusion with a relatively large thickness, used to fix the side of the blade body 200 where the bristle flattening member 241 is located, and the second locking member 132 can relatively firmly fix the blade body 200. The first locking member 131 is used to engage the side of the blade body 200 away from the bristle flattening member 241. Although the first locking member 131 also plays a role in fixing the blade body 200, it is easier to disengage than the second locking member 132, thus facilitating assembly and disassembly.

[0033] Regarding the first card connector 131, further details include... Figure 6 As shown, the thickness of the first protrusion of the first snap-fit ​​member is greater than that of the second protrusion of the first snap-fit ​​member. By setting snap-fit ​​members of two different thicknesses, both the firmness of the snap-fit ​​can be ensured, and disassembly can be better performed when external force is applied. For example... Figure 6 The snap-fit ​​connector shown, when removed from the scraped surface Figure 1 When the blade body 200 is pressed, due to the different thicknesses of the two protrusions, the second protrusion of the first locking piece can be disengaged first. After disengagement, the second protrusion of the first locking piece rests between the lower side of the blade body 200 and the lower part of the central through part 110 of the frame, providing support and making the disengagement of the first protrusion of the first locking piece more convenient.

[0034] like Figure 3 As shown, the blade body retaining member 130 has a blade body retaining groove 231, which is used to engage with the first retaining member 131. The blade body retaining groove 231 is located at the bottom of the blade body 100.

[0035] like Figure 1 As shown, the hair-flattening member 241 has a plurality of sheet-like adhesive strips arranged in parallel, and any one of the sheet-like adhesive strips is arranged parallel to the shaving blade 212; the end face of the sheet-like adhesive strip protrudes beyond the cutting edge of the blade in the blade holder 210.

[0036] like Figure 4 As shown, the frame body 110 has mounting guide posts 120 at both ends, and the blade holder 210 has mounting guide grooves 220 at both ends. When the blade body 200 is placed in the frame body 110, the mounting guide posts 120 are engaged in the mounting guide grooves 220. During installation, aligning the guide posts 120 with the mounting guide grooves 220 makes installation more convenient.

[0037] The peripheral portion 140 of the functional surface of the cutter head holder 100 is also provided with a lubricating element 300.

[0038] The blade head can be directly applied to the razor, and the handle is installed through the mounting part on the back of the blade head.

[0039] Regarding the blade head and blade body involved in this invention, it has a blade holder 210, the functional surfaces of which are provided side by side with a blade mounting groove and a bristle flattening member 241, and the blade mounting groove is provided with the blade mounting member 211; wherein,

[0040] The blade holder 211 has 6 blade slots, each of which is provided with a shaving blade 212, and the shaving blade 212 is positioned toward the hair-flattening member 241; the distance between the hair-flattening member 241 and the first blade is 0.5 to 1.5 mm and no hair guide is provided.

[0041] The six blades are then welded into the blade holder 211.

[0042] like Figure 7 As shown, the substrate surface 242 of the hair-flattening member 241 has a plurality of flexible sheet-like adhesive strips 243 arranged in parallel, and any one of the flexible sheet-like adhesive strips 243 is arranged parallel to the shaving blade 212; the end faces of the plurality of flexible sheet-like adhesive strips 243 all protrude beyond the cutting edges of the six blades in the blade holder 210; in use, as Figure 8 As shown, the end face of the flexible sheet adhesive strip 243 first presses the hair down, and as the blade moves, it also guides the hair, allowing the blade to cut the hair better.

[0043] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the protection scope of the present invention. The protection scheme of the present invention is defined by the appended claims.
