Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and more specifically to a razor head and a razor. Background Art

[0002] A razor is a tool used for shaving. It generally consists of a blade head and a handle. The blade head is fixed to the blade head. The blade head first contacts the skin surface. During the shaving process (usually shaving), the blade head moves from one area of the skin surface to another to shave the hair between them. The blade head cuts the hair to achieve the shaving effect. However, traditional blade heads are mostly installed in a single direction. When using such razor heads, they shave hair in a single direction. After a shave, the blade head needs to be lifted off the skin surface and then returned to its original position to shave again. This reciprocating operation is repeated until all the hair to be shaved is shaved. This shaving efficiency is low and the use is relatively laborious.

[0003] In response to the above problems, a Chinese utility model patent with the announcement number CN216000602U discloses a blade fixing structure of a T-shaped hand razor that can shave forward and backward, including a blade holder, a handle connecting structure is provided at the bottom of the blade holder, the blade holder includes a left blade holder and a right blade holder that are combined together to form a pointed structure, the left blade holder is provided with a left inclined portion obliquely downward to the left, a left mounting portion is provided on the left inclined portion, the right blade holder is provided with a right inclined portion obliquely downward to the right, a right mounting portion is provided on the right inclined portion, the left blade holder and the right blade holder are rotatably connected, and the blade holder is provided with a handle for connecting the left blade holder and the right blade holder. The right blade holder elastically expands to form a pointed structure, and when pressure is applied, the left or right blade holder is able to swing. In this technical solution, forward shaving is achieved through one shaving surface of the blade head, and reverse shaving is achieved through the other shaving surface of the blade head. The two shaving surfaces are switched by elastic swinging between the left and right blade holders for forward and reverse shaving. Each time the user uses the blade head, they need to place the blade head against the skin and swing the handle to rotate the blade head from one shaving surface to the other, thereby switching between forward and reverse shaving. Swinging is not only time-consuming and laborious, but also easy to scratch the skin if the handle is not swung properly. Therefore, there is still a need for a blade head that can quickly switch between forward and reverse shaving and can shave hair safely. Summary of the Invention

[0004] The technical problem to be solved by the present application is to provide a razor head and a razor, wherein the razor head is provided with a first blade group and a second blade group with cutting edges facing opposite directions. There is no need to lift the razor head or swing the handle, and only the blade holder needs to be moved back and forth to achieve two-way shaving of hair, which is labor-saving and safe to use.

[0005] The present application provides a razor head, comprising a blade holder, on which a first blade group and a second blade group are mounted, the first blade group and the second blade group being spaced apart along the same straight line, the cutting edge of the first blade group being arranged along a first direction, the cutting edge of the second blade group being arranged along a second direction, the first direction being opposite to the second direction, and the first blade group and the second blade group being moved back and forth to achieve bidirectional shaving of hair.

[0006] In this technical solution, the first blade group and the second blade group are respectively installed on the blade holder along the same straight line, and the cutting edges of the first blade group and the second blade group face oppositely. When the user applies force to the blade holder to move the blade holder along the first direction, the blade holder drives the first blade group and the second blade group to move synchronously. The first blade group moves so as to shave the hair along the first direction, and the first blade group preferentially shaves the longer hair on the skin surface. When the user applies force to the blade holder to move the blade holder along the second direction opposite to the first direction, the blade holder drives the first blade group and the second blade group to move synchronously in the opposite direction, and the second blade group moves so as to shave the hair along the second direction. The second blade group can not only perform a secondary shave on the front basis, but also shave other hair on the skin surface by slightly turning. There is no need to lift the blade head or swing the handle during the whole process. The blade holder can switch between forward and reverse shaving by moving back and forth, which is more labor-saving, smooth, safe and efficient to use.

[0007] As an improvement, the cutting edges of the first blade group and the cutting edges of the second blade group are arranged in opposite directions. In this technical solution, the first direction and the second direction are arranged in opposite directions, so that the cutting edges of the first blade group and the cutting edges of the second blade group are arranged in opposite directions. Hair shaved by the first blade group can be discharged through the first direction, and hair shaved by the second blade group can be discharged through the second direction, thereby preventing the shaved hair from accumulating between the first blade group and the second blade group, thereby improving shaving efficiency.

[0008] As an improvement, a first protection strip is provided between the first and second blade assemblies, and the tops of the first and second blade assemblies are both lower than the tops of the first protection strip. In this technical solution, by providing a higher first protection strip between the first and second blade assemblies, the first protection strip is higher than the cutting edges of the first and second blade assemblies. This protects the skin from contacting the second blade assembly when shaving with the first blade assembly, and protects the skin from contacting the first blade assembly when shaving with the second blade assembly, thereby improving user safety.

[0009] As an improvement, the first protective strip is constructed of plastic, sheet metal, or aluminum-coated plastic. In this technical solution, the first protective strip is constructed of one of the following: plastic, sheet metal, or aluminum-coated plastic. This not only provides a wider range of options but also offers a simple and reliable structure, extending the service life of the first protective strip.

[0010] As an improvement, the first blade set is composed of a plurality of first blades, and the second blade set is composed of a plurality of second blades. In this technical solution, the first blade set includes at least one first blade, and more preferably, multiple first blades are provided, and the multiple first blades are evenly arranged in sequence along the first direction. The second blade set includes at least one second blade, and more preferably, multiple second blades are provided, and the multiple second blades are evenly arranged in sequence along the second direction, which is conducive to improving shaving efficiency.

[0011] As an improvement, the spacing between two adjacent first blades is 0.5mm to 3mm, and the spacing between two adjacent second blades is 0.5mm to 3mm. In this technical solution, multiple first blades and multiple second blades are provided, and the distance between each first blade is 0.5mm to 3mm, and the distance between each second blade is 0.5mm to 3mm. This ensures that there is sufficient flushing space between two adjacent first blades and two adjacent second blades, preventing hair debris from clogging between the blades, thereby improving shaving efficiency and safety.

[0012] As an improvement, a second protective strip is provided between two adjacent first blades, and the top of the first blade assembly is lower than the top of the second protective strip; a third protective strip is provided between two adjacent second blades, and the top of the second blade assembly is lower than the top of the third protective strip. In this technical solution, a second protective strip is provided between each first blade, and the top of the second protective strip is slightly higher than the cutting edge of the first blade assembly, thereby better protecting the skin surface during shaving and improving user safety; similarly, a third protective strip is provided between each second blade, and the top of the third protective strip is slightly higher than the cutting edge of the second blade assembly, thereby better protecting the skin surface during shaving and improving user safety.

[0013] As an improvement, a lubricating strip is provided on the outer periphery of the blade holder, and the strip is distributed around the circumference of the blade holder. In this technical solution, the lubricating strip provided on the outer periphery of the blade holder can produce lubricating liquid when it comes into contact with water, thereby reducing irritation to the skin during shaving, allowing the user to shave more comfortably. Compared with the long strip lubricating strips in the prior art, the encircling lubricating strip provided in this solution can produce more lubricating liquid. Regardless of the angle from which the user shaves, part of the lubricating strip can be in contact with the skin surface, making it more comfortable and convenient to use.

[0014] As an improvement, one end of the first blade group and the second blade group are both positioned on the blade holder by a first fixing bar, and the other end of the first blade group and the second blade group are both positioned on the blade holder by a second fixing bar; the first fixing bar and the second fixing bar are both made of aluminum sheets or stainless steel sheets. In this technical solution, the first blade group and the second blade group are arranged in sequence along the width direction of the blade holder, and the first fixing bar and the second fixing bar are respectively provided at both ends of the blade holder along the length direction. The blade holder limits one end of the first blade group and the second blade group by the first fixing bar and limits the other end of the first blade group and the second blade group by the second fixing bar, thereby making the installation of the first blade group and the second blade group more stable and reliable. In addition, the first fixing bar and the second fixing bar are made of aluminum sheets or stainless steel sheets, which have a simple and reliable structure and a longer service life.

[0015] The present application may also provide a razor comprising a blade head of any of the aforementioned razors. In this technical solution, the blade head is detachably connected to a handle, and the blade head is provided with a first blade assembly and a second blade assembly with cutting edges facing opposite directions. During shaving, there is no need to lift the blade head or swing the handle; the user only needs to move the blade holder back and forth using the handle, which is labor-saving and safe.
