Description

Technical Field

[0001] The utility model relates to the technical field of shaving heads, in particular to an assembled shaving head. Background Art

[0002] As we all know, a razor is a shaving tool and a daily personal care product for men. They are generally divided into manual razors and electric razors. Electric razors are more commonly used by men due to their convenience and labor-saving nature. Electric razors can be further divided into rotating circular heads and reciprocating flat heads, depending on the blade type.

[0003] At present, the existing planar cutter heads are all integrally formed in structure. For example, Chinese patent No. 201810182537.2 discloses a razor cutting head, which mainly includes a fixed blade and a cutting blade that can be moved reciprocatingly relative to the fixed blade. The fixed blade includes a long strip body, a pressing long piece respectively arranged below the two long sides of the long strip body and parallel to the long strip body, and a bent connection part connected between the long side of the long strip body and the pressing long piece. The bent connection part and the pressing long piece form an inward return hook on the two long sides of the long strip body. The long strip body is provided with a plurality of tooth grooves on at least one long side, and the cutting blade is provided with cutting teeth corresponding to the tooth grooves. The cutting blade is inserted into the guide groove surrounded by the return hook and the long strip body. It can be seen that the existing flat cutter heads are all structurally configured as one piece, and are provided with cutting edges on both ends for cutting beards (the two ends are provided mainly to make shaving more efficient, and can achieve a reciprocating shaving with one push and one back). However, due to the integrated design, when the single-sided cutting edge is worn or the cutting is not sharp, it cannot meet the requirements of efficient shaving, and the entire cutter head will be scrapped as a whole, which easily leads to a waste of resources. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an assembled razor head.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An assembled razor head comprises two splicing units, each of which is provided with a connecting member for connecting to a razor main unit. A razor edge is provided on one end face of the splicing unit, and a mating portion is provided on the other end face of the splicing unit. The splicing unit is assembled with the other splicing unit by means of the mating portion.

[0007] Preferably, the two splicing monomers are centrally symmetrical structures.

[0008] Preferably, the splicing unit is provided with a tooth groove edge at the razor edge, the splicing unit has a built-in movable cavity, the movable cavity is provided with a blade that can slide repeatedly along the movable cavity, one end of the blade is provided with a serrated blade, the blade is placed at the tooth groove edge, the blade is provided with a convex head placed outside the cavity opening of the movable cavity, the number of the convex heads is at least two, and there is an insertion gap between the convex heads, and the insertion gap is inserted into the transmission part of the shaver host.

[0009] Preferably, the mounting portion includes an insert block and a slot, with the center of the splicing unit as a dividing line, the insert block is located at the lower half of the splicing unit, and the slot is located at the upper half of the splicing unit.

[0010] Preferably, the protruding heads of every two of the splicing units are respectively provided with a convex block and a groove which is matched with the convex block.

[0011] Preferably, a limit block is provided in the movable cavity of the splicing unit, a connecting rod is provided on the blade, the top end of the connecting rod is connected to the protrusion, a ring is formed between the connecting rod and the end face of the blade, the limit block is placed in the ring, and the distance from the limit block to the edge of the ring is the movable distance of the blade.

[0012] Due to the adoption of the above-mentioned scheme, the utility model is composed of two splicing monomers, so that the original integrated cutter head is divided into two components that can be disassembled and assembled with each other. Therefore, when a certain razor edge is damaged or cannot be used, the corresponding splicing monomer can be directly replaced without having to scrap the entire razor, which can effectively avoid waste of resources. At the same time, relying on the two splicing monomers to form a centrally symmetrical structure, the same set of molds can be used for processing during production. When stocking replaceable splicing monomers, there is no need to prepare two sets. Only one splicing monomer needs to be prepared, which is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, removable connections, or integral connections. They may refer to mechanical connections or electrical connections. They may refer to direct connections or indirect connections through an intermediary, and they may refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0020] like Figures 1 to 4 As shown, the present embodiment provides an assembled razor head, comprising two splicing monomers 1, each of which is provided with a connecting member 2 for connecting to a razor main unit, a razor edge 3 being provided on one end face of the splicing monomer 1, and a mating portion 4 being provided on the other end face of the splicing monomer 1, wherein the splicing monomer 1 is assembled with another splicing monomer 1 by means of the mating portion 4.

[0021] This embodiment is composed of two spliced ​​monomers 1, which split the original integrated cutter head into two components that can be disassembled and assembled with each other. Therefore, when a certain razor blade 3 is damaged or cannot be used, the corresponding spliced ​​monomer 1 can be directly replaced without having to scrap the entire razor head, which can effectively avoid waste of resources.

[0022] It should be noted that the splicing unit 1 must be assembled before being installed on the shaver main unit. The connection structure 2 of the shaver main unit only needs to ensure a fixed connection between the splicing unit 1 and the shaver main unit. Depending on the specifications of the corresponding shaver main unit, the corresponding connection member 2 will also vary. This example only illustrates a connection member 2 that relies on two side-mounted connections. This embodiment does not limit the specific connection structure 2 used.

[0023] Furthermore, to facilitate production and replacement without having to distinguish between the two splicing units 1, the two splicing units 1 of this embodiment are centrally symmetrical. Specifically, the splicing unit 1 is provided with a toothed edge 11 at the razor edge 3, and a movable cavity 12 is built into the splicing unit 1. The movable cavity 12 houses a blade 13 that can slide repeatedly along the movable cavity 12. One end of the blade 13 is provided with a serrated blade edge 14, and the blade 14 is placed at the toothed edge 11. The blade 13 is provided with a protrusion 15 located outside the cavity of the movable cavity 12. The number of the protrusions 15 is at least two and an even number. There is an insertion gap between the protrusions 15, and the insertion gap is plugged into the transmission part of the shaver main body. At the same time, the mating portion 4 includes an insert 16 and a slot 17. With the center of the splicing unit 1 as the dividing line, the insert 16 is located in the lower half of the splicing unit 1, and the slot 17 is located in the upper half of the splicing unit 1. The protrusions 15 of each of the two splicing units 1 are respectively provided with a protrusion 18 and a groove 19 that forms a mating connection with the protrusion 18. This arrangement allows only two splicing units 1 to be designed identically, allowing for mass production using a single mold. When replacing splicing units 1 at home, only one type is required, making daily use more convenient. Of course, it should be noted that, depending on the needs, the number of teeth in the trough 11, the spacing between the teeth, the shape and style of the blade 14, and the color of the splicing unit 1 itself can all be changed according to the design. If necessary, the mating portion 4 can be the same, while the color, trough 11 specifications, and blade 14 style can all be changed, allowing two sizes of razor blades to be present on a single razor head.

[0024] Furthermore, in order to prevent the blade 13 from having too large a range of movement or directly detaching from the active cavity 12, because the active cavity 12 is generally a through cavity during processing and production, the splicing unit 1 of this embodiment is provided with a limit block 21 in the active cavity 12, and a connecting rod 22 is provided on the blade 13. The top of the connecting rod 22 is connected to the protrusion 15, and a ring is formed between the connecting rod 22 and the end face of the blade 13. The limit block 21 is placed in the ring, and the distance from the limit block 21 to the edge of the ring is the movable distance of the blade 13.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
