Description

Technical Field

[0001] The utility model relates to the technical field of razor structures, in particular to a razor head limiting comb with a reinforcing column. Background Art

[0002] As people's living standards continue to improve, various small household appliances have become part of everyday life. Razors, used for shaving, are self-service tools, mostly used by adult men. Razors can be categorized into three types based on their structure: facial razors, electric razors, and mechanical razors.

[0003] Among them, the electric shaver uses a motor to drive the cutter head to rotate, or an eccentric shaft to drive the moving blade to reciprocate, to cut beards and excess hair. The limiting comb structure that guides the hair plays a vital role in guiding the hair and preventing large areas of skin from contacting the cutter head.

[0004] Moreover, as the design of the cutter head continues to be miniaturized and the cutting of hair, beard, etc. becomes more refined, the design of the cutter head limit comb is also gradually made into a smaller structure. The structure of the conventional size limit comb is shown in the technical solution CN220162515U. However, for the lighter and smaller limit comb, the structural strength of the main rod is difficult to ensure during use. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide a cutter head limit comb with a reinforced column to solve the problem that the structural strength of the main rod of the lighter and smaller limit combs in the prior art is difficult to ensure during use.

[0006] The utility model provides a cutter head limiting comb with a reinforcement column, which is assembled on at least one structure of the cutter head and the cutter head bracket, and includes a main rod, comb teeth, a reinforcement column and an assembly part;

[0007] The main rod is provided with a reinforcement column assembly groove;

[0008] The comb teeth are arranged along the length direction of the main rod, and the comb teeth are provided with a skin contact surface and a guide surface. The guide surfaces are arranged on both sides of the skin contact surface, and the guide surfaces of adjacent comb teeth are arranged opposite to each other;

[0009] The reinforcing column is inserted into the reinforcing column assembly groove of the main rod;

[0010] The assembly part is connected to at least one structure of the main rod and the comb teeth. A cutter head assembly portion is provided on the assembly part, and the cutter head assembly portion is connected to at least one structure of the cutter head and the cutter head bracket.

[0011] Different from the existing technology, the above technical solution has the following advantages: by setting the reinforcing column assembly groove of the main rod, the reinforcing column replaces a part of the main rod structure to bear the force, and a high-strength reinforcing column can be used to share the external force exerted on the comb teeth and the main rod. When the size of the limiting comb is adapted to the guidance of short hair and a miniaturized and lightweight design is performed, it can ensure that the main rod structure is not easily damaged, and ensure that the comb teeth are stably guided and the arrangement position does not produce displacement and rotation.

[0012] As a preferred embodiment of the present application, the reinforcing column assembly groove of the main rod is provided with injection-molded fixing holes on the side of the main rod provided with the comb teeth. By providing the injection-molded fixing holes on the side of the main rod provided with the comb teeth, when the main rod and comb teeth are supported by injection molding, the injection-molded material can be tightly coated on the reinforcing column, ensuring the efficient transmission of external force to the reinforcing column and the stability of the reinforcing column assembly state during long-term use.

[0013] As a preferred embodiment of the present application, the reinforcing column assembly slot of the main rod is provided with an assembly hole between the assembly parts of the main rod, and the assembly hole is connected to the reinforcing column assembly slot. By providing the assembly hole between the assembly parts of the main rod in the reinforcing column assembly slot of the main rod, the operator is facilitated to install the reinforcing column.

[0014] In a preferred embodiment of the present application, the cutter head mounting portion of the assembly is a snap-in hole, and the snap-in holes of the assembly on each side are arranged opposite each other, and the assembly is connected to at least one structure of the cutter head and the cutter head support via the snap-in holes. By providing the oppositely arranged snap-in holes as the cutter head mounting portion and connecting to at least one structure of the cutter head and the cutter head support, overlap or interference with the teeth or movable blade structure of the cutter head and the area where the limit comb assembly is located are prevented from causing direct contact, thereby preventing the limit comb from affecting the performance of the cutter head.

[0015] As a preferred embodiment of the present application, the assembly part is provided with an extension portion, which is adapted to the cutter head support. By providing the extension portion, the assembly part is easily assembled on the cutter head support and the assembly contact area and stability are improved.

[0016] As a preferred embodiment of the present application, the comb teeth are provided with guiding cut surfaces, which are arranged on the skin contact surface and are inclined. By providing the guiding cut surfaces, the guiding efficiency of the comb teeth on the hair and skin is improved.

[0017] As a preferred embodiment of the present application, a reinforcement bevel is further included, which is connected to the main rod and the comb teeth. By providing the reinforcement bevel, the structural strength of the connection between the main rod and the comb teeth is improved, and the compatibility of the main rod structural strength increased by the reinforcement column with the comb teeth is improved.

[0018] As a preferred embodiment of the present application, the assembly is connected to the comb teeth at both ends of the main rod. By adopting the arrangement of the assembly being connected to the comb teeth at both ends of the main rod, the structural strength of the connection between the assembly, the main rod and the comb teeth is improved.

[0019] As a preferred embodiment of the present application, the reinforcing column is made of metal. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Please also refer to Figures 1 to 5 The inventor provides a cutter head limiting comb with a reinforcing column. The cutter head limiting comb is assembled on at least one structure of the cutter head and the cutter head bracket, and includes a main rod 10, comb teeth 20, a reinforcing column 30 and an assembly part 40;

[0045] The main rod 10 is provided with a reinforcement column assembly groove 11;

[0046] The comb teeth 20 are arranged along the length direction of the main rod 10. The comb teeth 20 are provided with a skin contact surface 21 and a guide surface 22. The guide surfaces 22 are provided on both sides of the skin contact surface 21. The guide surfaces 22 of adjacent comb teeth 20 are arranged opposite to each other.

[0047] The reinforcing column 30 is inserted into the reinforcing column assembly groove 11 of the main rod 10;

[0048] The assembly part 40 is connected to at least one structure of the main rod 10 and the comb teeth 20. A cutter head assembly portion 41 is provided on the assembly part 40. The cutter head assembly portion 41 is connected to at least one structure of the cutter head and the cutter head bracket.

[0049] According to the above structure, during the installation of the cutter head limiting comb with a reinforcement column, the cutter head is assembled on the cutter head bracket. The reinforcement column assembly groove 11 provided on the main rod 10 provides space for the reinforcement column 30 to be installed. After the reinforcement column 30 is installed in the reinforcement column assembly groove 11 on the main rod 10, it contacts the reinforcement column assembly groove 11 of the main rod 10 and shares the external force with the main rod 10. In addition, the main rod 10 is buckled onto at least one structure of the cutter head and the cutter head bracket through the cutter head assembly portion 41 of the assembly parts 40 on both sides. The cutter head and the cutter head bracket are pre-set with a docking structure adapted to the cutter head assembly portion 41, which facilitates the assembly of the assembly parts 40.

[0050] After assembly, during use of the cutter head limiting comb with a reinforcing column, the arranged comb teeth 20 contact the user's skin via the skin contact surface 21 and pull and guide the skin along the length of the skin contact surface 21, so that under the obstruction of the guide surface 22, the hair and beard reach the area where the cutter head is located for cutting. During movement, the comb teeth 20 are subjected to external forces that deviate from the guiding direction. The external forces are transmitted by the comb teeth 20 to the main rod 10 and further to the reinforcing column 30, which then shares the external forces. By providing the reinforcing column assembly groove 11 of the main rod 10, the reinforcing column 30 replaces a portion of the main rod 10 structure to bear the forces, and the high-strength reinforcing column 30 is used to share the external forces exerted on the comb teeth 20 and the main rod 10. When the size of the limiting comb is adapted to the guide adaptation of short hair and the miniaturization and lightweight design are implemented, the main rod 10 structure is ensured to be less susceptible to damage, and the comb teeth 20 are ensured to be stably guided and arranged without displacement or rotation.
