Description

Technical Field

[0001] This invention relates to the field of razor technology, and more specifically to a razor with a limiting function. Background Technology

[0002] A hair shaving tool is a tool used to remove hair. It includes a fixed blade and a moving blade. The fixed blade includes a fixed blade holder and a fixed blade, while the moving blade includes a moving blade holder and a moving blade. Both the moving blade and the fixed blade have toothed cutting edges at their front ends. When the hair shaving tool is working, the moving blade moves horizontally relative to the fixed blade, so that the toothed cutting edges of the moving blade produce a horizontal shearing effect relative to the toothed cutting edges of the fixed blade, thereby achieving the removal of hair.

[0003] To ensure that the moving blade moves parallel to the fixed blade, the vertical movement of both blades needs to be restricted. Existing shavers typically use a pressure elastic element for this purpose. The fixed end of the pressure elastic element is fixed to the fixed blade, while the pressure-applying end is fixed to the moving blade, thus pressing the moving blade against the fixed blade and restricting its vertical movement relative to the fixed blade.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] The present invention will now be further described with reference to the accompanying drawings.

[0045] This invention provides the following technical solution:

[0046] As attached Figures 1-15As shown, this invention discloses a shaver with a limiting function, including a moving blade 1, a fixed blade 2, and a limiting mechanism 3 for limiting the vertical position of the moving blade 1 and the fixed blade 2. The limiting mechanism 3 is disposed between the moving blade 1 and the fixed blade 2, with its two ends correspondingly connected to the moving blade 1 and the fixed blade 2. The limiting mechanism 3 limits the relative displacement of the moving blade 1 and the fixed blade 2 in the vertical cutting direction. The limiting mechanism 3 includes a fixed blade limiting mechanism 4 disposed on the fixed blade 2 and a moving blade limiting mechanism 5 disposed on the moving blade 1. Specifically, the fixed blade 2 includes a fixed blade seat 6 and a fixed blade 7, and the moving blade 1 includes a moving blade seat 8 and a moving blade 9.

[0047] A guide mechanism (not shown) is provided between the fixed blade 2 and the moving blade 1. The guide mechanism drives the moving blade 1 or the fixed blade 2 to move along the cutting direction on the other one.

[0048] Specifically, the fixed blade 7 and the fixed tool holder 6 can be an integral structure or a separate structure. Those skilled in the art should understand that when the fixed tool holder 6 and the fixed blade 7 are separate structures, they should be fixedly connected in a fixed relative position. The moving blade 9 and the moving tool holder 8 can be an integral structure or a separate structure. In actual application, the choice can be made according to actual needs.

[0049] In one embodiment, the moving blade limiting mechanism 5 and the fixed blade limiting mechanism 4 are integrally formed on the moving blade 1 and the fixed blade 2, respectively. The moving blade limiting mechanism 5 is a limiting part 10 formed on the moving blade 1, and the fixed blade limiting mechanism 4 is a connecting part 11 formed on the fixed blade 2. The limiting part 10 extends into the connecting part 11 and engages with it. The limiting part 10 is a limiting block formed on the moving blade 1, located on the side of the moving blade 1 closest to the fixed blade 2. The connecting part 11 is a limiting groove formed on the fixed blade 2, and the limiting block extends into the limiting groove and engages with it. There is a gap of 0-0.05 mm between the limiting part and the connecting part. In this invention, the limiting part 10 can be formed on either the moving blade 1 or the fixed blade 2, and the connecting part can be formed on both the moving blade 1 and the fixed blade 2.

[0050] In the preferred embodiment, since the moving blade holder 8 is made of plastic, the moving blade limiting mechanism 5 is formed on the moving blade holder 8 and is also made of plastic. In contrast, when the moving blade limiting mechanism 5 is set on the moving blade 9, it is made of metal. This combination of plastic moving blade limiting mechanism 5 and metal fixed blade limiting mechanism 4 reduces the noise generated between the fixed blade limiting mechanism 4 and the moving blade limiting mechanism 5, and the friction between metal and plastic does not easily generate heat.

[0051] In another embodiment, the fixed-blade limiting mechanism 4 and the moving-blade limiting mechanism 5 are both formed on the fixed-blade 2 and the moving-blade 1 respectively through a secondary forming process. The secondary forming methods for fixing the fixed-blade limiting mechanism 4 and the moving-blade limiting mechanism 5 can be secondary injection molding, spot welding, laser welding, snap-fitting, and bonding. The fixed-blade limiting mechanism 4 is a connecting part 11 formed on the fixed-blade 2, and the connecting part 11 can be a groove / protrusion. The fixed-blade limiting mechanism 5 is a groove / protrusion formed on the moving-blade, and the shapes of the groove / protrusion are correspondingly set, and the shapes of the groove / protrusion can be T-shaped, π-shaped, or L-shaped. The fixed-blade limiting mechanism 4 and the moving-blade limiting mechanism 5 are connected and cooperate. In this embodiment, the limiting part 10 can be formed on the fixed-blade 2 or the moving-blade 1, and the connecting part 11 can be formed on the fixed-blade 2 or the moving-blade 1.

[0052] Reference Appendix Figure 7-8 As shown, in another embodiment, the limiting mechanism 3 is detachably installed between the moving blade 1 and the fixed blade 2, the fixed blade limiting mechanism 4 is detachably installed on the fixed blade 2, and the moving blade limiting mechanism 5 is detachably installed on the moving blade 1.

[0053] In one embodiment, the fixed tool limiting mechanism 4 is a protrusion / or groove detachably mounted on the fixed tool 2, and the fixed tool limiting mechanism 5 is a protrusion / or groove detachably mounted on the moving tool 1. The fixed tool limiting mechanism 5 and the fixed tool limiting mechanism 4 are connected in a fitting manner. The detachable fixed tool limiting mechanism 4 and the fixed tool limiting mechanism 5 reduce the machining difficulty. The fixed tool limiting mechanism 5 and the fixed tool limiting mechanism 4 can be machined on external parts, and then the moving tool limiting mechanism 5 and the fixed tool limiting mechanism 4 can be correspondingly mounted on the moving tool 1 and the fixed tool 2, preventing overall defects caused by machining errors when directly machining the moving tool limiting mechanism 5 and the fixed tool limiting mechanism 4 on the moving tool 1 or the fixed tool 2. The fixed tool limiting mechanism 4 can be a connecting part 11 machined on an external part, a limiting part 10 machined on an external part, and the corresponding parts are mounted on the moving tool 1 and the fixed tool 2, so that the internal part 10 and the connecting part 11 of the separately machined part can then perform a limiting fit.

[0054] To enable the limiting mechanism 3 to more accurately limit the upper and lower positions of the moving blade 1 and the fixed blade 2, the limiting mechanism 3 is an adjustable limiting mechanism. A height adjustment device (not shown) is provided on the limiting mechanism 3. This height adjustment device compensates for the lack of precision in the fit between the moving blade 1 and the fixed blade. The height adjustment device is a screw; by rotating the screw on the fixed blade 2 and / or the moving blade 1, the screw moves up and down, thus achieving height adjustment. The height adjustment device is located on the side of the limiting mechanism 3 close to the moving blade 1 and / or the fixed blade 2, allowing for a more precise fit between the fixed blade limiting mechanism 4 and the fixed blade limiting mechanism 5 when the moving blade 1 and the fixed blade 2 are in the upper and lower limit positions, thereby improving the accuracy of the limit.

[0055] Reference Appendix Figure 4 In one embodiment, a sliding member 13 is provided on the limiting mechanism 3. The two ends of the sliding member 13 abut against the moving blade limiting mechanism 5 and the fixed blade limiting mechanism 4, respectively. The sliding member 13 can be a ball, roller, or rubber ball. A groove 14 is formed on the moving blade limiting mechanism 5, and the sliding member 13 is placed within the groove 14. Since the diameter of the sliding member 13 is larger than the diameter of the groove 14, one end of the sliding member 13 extends out of the groove 14 and abuts against the fixed blade limiting mechanism 4. In this embodiment, the groove 14 can be provided on either the moving blade limiting mechanism 5 or the fixed blade limiting mechanism 4. When the groove 14 is provided on the fixed blade limiting mechanism 4, one end of the sliding member 13 extends out of the groove 14 and abuts against the moving blade limiting mechanism 5. The sliding member 13 enables the contact between the fixed blade limiting mechanism 4 and the moving blade limiting mechanism 5 to achieve point contact or line contact through different sliding members 13, thereby reducing friction between the moving blade limiting mechanism 5 and the fixed blade limiting mechanism 4. In another embodiment, an elastic element (not shown) may be added between the slider 13 and the groove 14. The elasticity of the elastic element is used to apply pressure to the moving blade limiting mechanism 5 or the fixed blade limiting mechanism 4 in the direction of pressure cutting, thereby improving the limiting accuracy.

[0056] Reference Appendix Figure 3 As shown, in one embodiment, an elastic element 12 can also be provided on the limiting mechanism 3. The elastic element 12 abuts against the fixed tool limiting mechanism 5 and the fixed tool limiting mechanism 4. Four elastic elements 12 are provided, respectively distributed between the fixed tool limiting mechanism 4 and the fixed tool limiting mechanism 5. Compared with the limiting mechanism without elastic elements 12, the setting of elastic elements 12 can achieve flexible cooperation between the elastic element 12 and the moving tool 1 or the fixed tool 2. Moreover, the processing requirements of the elastic element 12 are low and the structure is simple. The elastic element 12 can be plastic, elastic silicone, TPE / TPR, rubber and spring. The two ends of the elastic element abut against the moving tool and the fixed tool respectively.

[0057] Reference Appendix Figure 9-11As shown, in one embodiment, a limiting support member 15 is further provided between the fixed blade 2 and the moving blade 1. The limiting support member 15 and the moving blade 1 can be an integral structure or a separate structure. The end of the limiting support member 15 that abuts against the fixed blade 2 can be a spherical protrusion. The fixed blade 2 forms a support groove 16 corresponding to the position of the spherical protrusion and connects with it. In another embodiment, the support groove 16 that cooperates with the spherical protrusion can also be formed on the external part 25. The external part 25 with the support groove 16 is fixed on the fixed blade. This arrangement can reduce the number of steps that need to be processed directly on the fixed blade 2, improve the processing accuracy, and the external part 25 can be replaced after long-term use. In this embodiment, a spring member 17 is also provided between the moving blade 1 and the fixed blade 2. The spring member 17 can be a spring sheet or a spring. In this embodiment, the spring 17, made of elastic balls or elastic rubber, consists of two spring pieces arranged in a figure-eight shape. One end of the spring 17 is connected to the moving blade 1, and the other end abuts against the fixed blade 2. By applying pressure to the moving blade 1, the spring 17 deforms, thereby changing the distance between the moving blade 1 and the fixed blade 2. In another embodiment of this solution, when the spring 17 is a spring, both ends of the spring are connected to the moving blade and the fixed blade respectively. By applying pressure to the moving blade 1, the spring deforms and compresses, thereby changing the distance between the moving blade 1 and the fixed blade 2.

[0058] Reference Appendix Figure 12-13 As shown, a height adjustment component 18 is also provided between the moving blade 1 and the fixed blade 2. The height adjustment component 18 is a shim, which is fixed between the fixed blade 2 and the limiting support component 15. An adjusting screw 19 is provided at the bottom of the fixed blade 2. The adjusting screw 19 passes through the fixed blade 2 and abuts against the shim. By rotating the adjusting screw 19, the shim rises or falls. Since the moving blade 1 is connected to the limiting support component 15, the rise and fall of the shim will drive the rise and fall of the limiting support component 15, thereby changing the distance between the moving blade 1 and the fixed blade 2. In another embodiment, the height adjustment component can also be replaced by a spring. The spring is installed between the fixed blade and the limiting support component, so that the two ends of the spring are connected to the fixed blade and the limiting support component respectively. When pressure is applied to the limiting support component, the spring will deform, so that the distance between the limiting support component and the fixed blade can be changed at any time under different pressure conditions.

[0059] Reference Appendix Figure 14-15As shown, in another embodiment, the moving blade limiting mechanism 5 forms two moving blade seat ribs 24 with inclined surfaces 20. The two moving blade seat ribs 24 are symmetrically arranged. The inclined surfaces 20 on the moving blade seat ribs 24 are concave to form spherical grooves 21. Steel balls 22 are embedded in the spherical grooves 21. The fixed blade 2 forms a limiting groove 23 corresponding to the moving blade 1 limiting mechanism. The shape of the limiting groove 23 corresponds to the moving blade limiting mechanism 5. One end of the steel ball 22 is embedded in the spherical groove 21, and the other end extends out of the spherical groove 21 and is press-fitted with the limiting groove 23, thereby making the moving blade 1 and the fixed blade 2 fit tightly together. In this embodiment, the moving blade limiting mechanism 5 and the moving blade seat 8 are an integral structure. Both the moving blade limiting mechanism 5 and the moving blade seat 8 are made of plastic. Since the steel ball 22 is a rigid material and the plastic moving blade limiting mechanism 5 is a flexible material, the two together can make the steel ball 22 precisely abut against the spherical groove 21 and the limiting groove 23.
