Description

[Technical Field]

[0001] This utility model relates to a blade holder for a rotary shaver, and also to a blade head assembly. [Background Technology]

[0002] Existing rotary shavers, such as the Chinese patent CN219466217U entitled "A Shaver Head and Shaver," typically include a base and a head cover detachably attached to the base. The head cover has several suspension rings on which blades are mounted. These rings rotatably connect the blades to the head cover, allowing them to float. Inside the blades are moving blades, driven by a drive shaft on the base to rotate and work with the blades to cut hairs entering the pores. The head cover needs to be installed and connected to the shaver head base, and it also needs to rotatably connect to the suspension rings for them to float. Therefore, the head cover is generally quite complex, usually injection molded from engineering plastics, and to ensure strength, the material thickness and volume are usually relatively large. Furthermore, the head cover, base, and blades form a closed or nearly closed space, resulting in a complex structure that is not conducive to hair and dandruff removal.

[0003] This utility model is a technical improvement made based on this situation. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a blade holder for a rotary shaver, which is integrally formed of metal and has a cantilever integrally formed on the holder body for suspending the suspension ring. The structure is simple and helps to simplify the structure of the blade head assembly.

[0005] To solve the above-mentioned technical problems, the present invention provides a blade holder for a rotary shaver, comprising a holder body, wherein a plurality of pairs of cantilever arms are provided on the holder body in a circumferential direction, and a groove for installing a suspension ring is provided between each pair of cantilever arms. The cantilever arms are provided with a rotatable connection structure, and the holder body and the cantilever arms are integrally formed of metal.

[0006] As described above, the blade holder of a rotary shaver has two or more pairs of cantilever arms. The cantilever arms extend laterally from the holder body, and the holder body is laterally concave and forms a groove with the cantilever arms. The groove is vertically continuous, and the groove has a side opening at the outer end of the cantilever arm.

[0007] As described above, the blade holder of a rotary shaver has a rotating connection structure that is an integrally formed suspension shaft on the inner side of the cantilever.

[0008] As described above, in the blade holder of a rotary shaver, two adjacent cantilever arms on two pairs of cantilever arms are connected as one unit and form a gripping part on the outside for fingers to grasp.

[0009] As described above, the blade holder of a rotary shaver has a gripping part that is laterally concave in an arc shape, and its surface is provided with raised stripes.

[0010] As described above, in a rotary shaver foil holder, the gripping portion extends downward and protrudes below the holder body.

[0011] The blade holder of a rotary shaver as described in any one of the above, wherein the holder body and the cantilever are integrally formed by powder metallurgy.

[0012] Another technical problem to be solved by this utility model is to provide a cutter head assembly, wherein the cutter head support is integrally formed of metal, and a cantilever is integrally formed on the support body for suspending the suspension ring. The structure is simple and is conducive to simplifying the structure of the cutter head assembly and the removal of lint and chips from the cutter head assembly.

[0013] To solve the above-mentioned technical problems, the present invention provides a blade head assembly of a blade holder for a rotary shaver, wherein each pair of cantilever arms is connected by a suspension ring through a rotatable connection structure, the suspension ring is installed in a groove and can swing relative to the holder body, and the suspension ring is provided with a blade net that can swing with the suspension ring.

[0014] As described above, in a cutter head assembly, there are two or more pairs of cantilever arms. The cantilever arms extend laterally from the support body. The support body is laterally concave and forms a groove with the cantilever arms. The groove is vertically continuous. The groove has a side opening at the outer end of the cantilever arm. The rotating connection structure is a suspension shaft integrally formed on the inner side of the cantilever arm. The suspension ring has a suspension hole that mates with the suspension shaft. The suspension ring has a guide angle on one side of the suspension hole to guide the suspension shaft into the suspension hole when the suspension ring is pushed into the groove from the side opening.

[0015] As described above, in a blade assembly, two adjacent cantilever arms on two pairs of cantilever arms are connected as one unit and form a gripping part on the outside for fingers to grasp. The gripping part is a laterally concave arc-shaped structure.

[0016] As described above, in a cutter head assembly, the portion of the suspension ring corresponding to the groove has a pressing edge extending above the support body. When the suspension ring swings inward, the pressing edge presses against the support body, thereby restricting the suspension ring from continuing to swing inward. The portion of the suspension ring located outside the groove has a downward-facing arc-shaped edging. The arc-shaped edging has a limiting portion corresponding to the outer end of the cantilever. When the suspension ring swings outward, the limiting portion presses against the outer end of the cantilever, thereby restricting the suspension ring from continuing to swing outward.

[0017] In one type of cutter head assembly as described above, the suspension ring and the cutter head are integrally formed by powder metallurgy.

[0018] As described above, in one type of blade assembly, a magnet mounting hole is integrally formed on the support body, and a magnet is fixed in the magnet mounting hole.

[0019] As described above, in a blade assembly, a light guide hole is integrally formed on the support body, and a light guide component is provided in the light guide hole.

[0020] As described above, in one type of blade assembly, the support body has an integrally formed cooling outlet hole that extends vertically through the support body, located on the inner side of the groove.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The blade holder of this utility model is a metal holder with good structural strength. It can suspend the suspension ring through two opposing cantilever suspension rings, avoiding the blade holder from completely surrounding the suspension rings. This makes it easier to form a simpler structure between the blade holder and the suspension rings, reducing the volume and facilitating the removal of lint and chips and cleaning.

[0023] 2. The laterally extending cantilever allows the suspension ring to be installed laterally, which is beneficial for the positioning and / or clamping of tooling fixtures and facilitates assembly production.

[0024] 3. The bracket body, cantilever and suspension shaft are integrally formed by powder metallurgy, which has good structural strength, which helps to reduce the material thickness and volume of the knife net bracket and simplify the knife net bracket.

[0025] 4. The blade holder is formed by powder metallurgy, which has good structural strength and makes it easy to form various functional structures such as suspension shaft, gripping part, stripes, magnet mounting holes, light guide holes or cooling hole, while avoiding excessive size.

Detailed Implementation Methods

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] like Figures 1 to 4 The blade holder 1 of a rotary shaver shown includes a holder body 11, on which a plurality of pairs of cantilever arms 12 are provided in a circumferential direction. A groove 13 for mounting a suspension ring 2 is provided between each pair of cantilever arms 12. A rotatable connection structure is provided on the cantilever arms 12. The holder body 11 and the cantilever arms 12 are integrally formed of metal.

[0039] Preferably, the support body 11 and the cantilever 12 are integrally formed by powder metallurgy, preferably by stainless steel powder forming, which has good structural strength, helps to reduce the material thickness and volume of the knife net support 1, and simplifies the knife net support 1.

[0040] like Figure 5 The cutter head assembly using the above-mentioned cutter head bracket 1 is shown in which each pair of cantilever 12 is connected by a rotatable connection structure with a suspension ring 2. The suspension ring 2 is installed in the groove 13 and can swing relative to the bracket body 11. The suspension ring 2 is provided with a cutter head 3 that can swing with the suspension ring 2.

[0041] The blade holder 1 is a metal holder with good structural strength. The suspension ring 2 can be suspended by two opposite cantilevers 12, which avoids the blade holder 1 completely surrounding the suspension ring 2. This makes it easier for the blade holder 1 and the suspension ring 2 to form a simpler structure, reduce the volume, and facilitate the removal of lint and chips and cleaning.

[0042] Preferably, the cantilever 12 has two or more pairs, the cantilever 12 extends laterally from the support body 11, the support body 11 is laterally concave and surrounds the cantilever 12 to form a groove 13 with a laterally concave shape, the groove 13 is vertically continuous, and the groove 13 has a side opening 14 at the outer end of the cantilever 12. The rotating connection structure is a suspension shaft 15 integrally formed on the inner side of the cantilever 12 by powder metallurgy.

[0043] like Figure 6 As shown, the suspension ring 2 has a suspension hole 21 that mates with the suspension shaft 15. A guide angle 22 is provided on one side of the suspension ring 2 near the suspension hole 21, guiding the suspension shaft 15 into the suspension hole 21 when the suspension ring 2 is pushed into the groove 13 from the side opening 14. During installation, the suspension ring 2 is positioned with the side opening 14 facing the side opening 14 and the guide angle 22 facing the suspension shaft 15. The suspension ring 2 is then pushed laterally into the groove 13, and the suspension shaft 15 is easily inserted into the suspension hole 21 via the guide angle 22. Lateral insertion of the suspension ring 2 also allows the cantilever 12 to be appropriately elastically extended, facilitating the insertion of the suspension shaft 15 into the suspension hole 21. The laterally extending cantilever 12 allows the suspension ring 2 to be installed laterally, which is beneficial for the positioning and / or clamping of tooling fixtures and facilitates assembly production.

[0044] Of course, it can also be like Figure 7 As shown, the suspension ring 2 is provided with a guide angle 22 below the suspension hole 21 to guide the suspension shaft 15 from bottom to top into the suspension hole 21, and the suspension ring 2 is installed into the groove 13 from top to bottom.

[0045] Of course, the rotating connection structure can also be a shaft hole, through which the suspension ring 2 is rotatably connected to the bracket body 11 by a pin passing through the shaft hole and the suspension hole 21. The figure is omitted here.

[0046] Preferably, two adjacent cantilever arms 12 on two adjacent pairs of cantilever arms 12 are connected as one unit and form a gripping part 16 on the outer side for finger gripping, such as Figure 5 , 7 As shown in Figure 9, the suspension ring 2 is mounted on the bracket body 11, and the gripping part 16 is exposed on the outside of the suspension ring 2 so that different fingers can grip the entire blade assembly by pinching different gripping parts 16.

[0047] Preferably, the gripping part 16 has a laterally concave arc-shaped structure, and its surface is provided with protruding stripes 17. The stripes 17 are integrally formed on the gripping part 16 by powder metallurgy, which facilitates finger gripping. In addition, the concave gripping part 16 avoids the cantilever 12 from being too large, so that when the suspension ring 2 is installed laterally from the side opening 14, the cantilever 12 can be appropriately elastically stretched.

[0048] Preferably, the gripping part 16 extends downward and protrudes below the support body 11, so that the thickness of the support body 11 in the height direction is reduced, while the width of the gripping part 16 in the height direction is increased, so that it can be better gripped by the fingers.

[0049] Preferably, the portion of the suspension ring 2 corresponding to the groove 13 is provided with a pressing edge 23 extending above the bracket body 11. When the suspension ring 2 swings inward, the pressing edge 23 presses against the bracket body 11, thereby limiting the maximum angle of the suspension ring 2 swinging inward. The portion of the suspension ring 2 located outside the groove 13 is provided with a downward-facing arc-shaped edge 25. The arc-shaped edge 25 is used to prevent shavings from being thrown outward by the razor, and to facilitate the shavings falling downward onto the base of the razor head. The arc-shaped edge 25 is provided with a limiting part 24 corresponding to the outer end of the cantilever 12. When the suspension ring 2 swings outward, the limiting part 24 presses against the outer end of the cantilever 12, thereby limiting the maximum angle of the suspension ring 2 swinging outward.

[0050] like Figure 1 As shown, the upper surface of the support body 11 is divided into multiple surfaces corresponding to multiple grooves 13. For each groove 13, the upper surface of the cantilever 12 extends along the corresponding upper surface of the support body 11, and as shown... Figure 8 and 9 As shown, the upper surface of the cantilever 12 slopes downwards from the outer end inwards, as... Figure 8 The blade mesh 3 is coaxially mounted on the suspension ring 2. When the suspension ring 2 swings inward so that the pressing edge 23 presses against the corresponding upper surface of the bracket body 11, the top surface of the blade mesh 3 can tilt inward.

[0051] like Figure 4 In the embodiment shown, the support body 11 has a magnet mounting hole 18 integrally formed by powder metallurgy. The structure is simple and easy to form. A magnet 4 is fixed in the magnet mounting hole 18 so that it can be magnetically attached to the base of the cutter head.

[0052] like Figure 2 , 3 In the embodiment shown, the support body 11 is integrally formed with a light guide hole 19 by powder metallurgy, which has a simple structure and is easy to form. The light guide hole 19 is provided with a light guide component 5 so that the cutter head assembly can guide and emit light. The support body 11 is made of metal material that is resistant to high temperature, and the light guide component 5 can be injection molded into the light guide hole 19.

[0053] like Figure 3In the embodiment shown, the bracket body 11 has an integrated cooling outlet 10 formed by powder metallurgy on the inner side of the groove 13, which runs through the bracket body 11 from top to bottom. This outlet allows the cooling end of the cooling module to pass through and be exposed from bottom to top. The cooling end of the cooling module can contact the skin to provide a cooling sensation during shaving. The technical solution of the cooling module is referenced in Chinese patent CN219466216U, entitled "Shaver".

[0054] like Figure 6-9 In the illustrated embodiment, the suspension ring 2 and the blade net 3 are two independent components. The blade net 3 is mounted on the suspension ring 2, and the blade net 3 is fixedly or floatingly connected to the suspension ring 2. Alternatively, as shown... Figure 10 The blade mesh 3 and the suspension ring 2 are integrally formed by powder metallurgy, which has a simple structure, reduces the number of parts and eliminates the assembly process between the blade mesh 3 and the suspension ring 2, which helps to optimize the inner space of the blade mesh 3 and the suspension ring 2 and increase the space for removing hair and chips.
