Description

Technical Field

[0001] This invention relates to the field of electric shavers, and in particular to a floating blade structure for an electric shaver. Background Technology

[0002] Electric shavers are a subcategory of personal care small appliances. They generally consist of a stainless steel mesh cover, inner blades, a micro motor, and a housing. Driven by the micro motor, the inner blades cut the beard and hair that extend into the mesh cover.

[0003] In existing shavers, the foil section of the head cover can typically move up and down for a better user experience. Since shavers need to be removed frequently for internal cleaning, if the inside is not cleaned for a long time, dirt can easily accumulate inside the shaver head, affecting its lifespan. The traditional foil installation and removal structure is inconvenient for users, and it is easy to damage small plastic parts during the process, rendering the entire shaver head unusable and requiring replacement.

[0004] To address these issues, we propose a floating blade structure for electric shavers. Summary of the Invention

[0008] The inner side of the first slide groove is movably connected to a first slider, the top of the first slider is fixedly connected to a second limiting plate, and the middle of the top of the second limiting plate is movably connected to two second movable rods. The four corners of the top of the inner cavity of the cutter head shell are provided with third slide grooves, the inner side of the third slide groove is movably connected to a first movable rod, the inner side of the first movable rod is fixedly connected to a fourth spring, and the bottom of the first movable rod is movably connected to the second movable rod.

[0009] In a further embodiment, a foil mechanism is installed on the inner surface of the razor head. The foil mechanism includes a through hole, which is circular, and a placement groove is formed on the inner side of the through hole.

[0010] In a further embodiment, a blade holder is placed in the inner cavity of the placement groove. The blade holder is circular, and the top edge of the blade holder contacts the inner surface of the placement groove.

[0011] In a further embodiment, the top of each blade holder is provided with a groove, the groove being annular, and a first spring is fixedly connected to the bottom of each groove cavity.

[0012] In a further embodiment, the number of first springs in the inner cavity of the groove is seven, and the first springs are distributed in an equidistant ring in the inner cavity of the groove, and a floating ring is fixedly connected to the top of each of the first springs.

[0013] In a further embodiment, a blade mesh body is fixedly connected to the top of each floating ring, and the top of each blade mesh body has a ring-shaped opening with mesh, and the blade mesh body is made of stainless steel.

[0014] In a further embodiment, a connecting plate is fixedly connected to the bottom of each of the second sliders, and the connecting plates are arranged symmetrically.

[0015] In a further embodiment, a second limiting groove is provided at the rear end of the inner cavity of the second slide groove, the rear end of the third slider is movably connected to the outer side of the inner cavity of the second limiting groove, and a first limiting groove is provided on the front side of the connecting block.

When the first movable rod moves outward, it stretches the fourth spring, causing it to deform. After the blade holder is inserted into the placement groove, the third and fourth springs quickly reset after losing pressure, causing the first and second limiting plates to reset and lock the blade holder in place. During disassembly, simply press the connecting plate inward. The connecting plate drives the second slider to move inward, compressing the second spring and causing it to deform. The second slider, through the connecting rod, drives the connecting block to move inward, causing the first limiting plate to move inward and release the restriction on the blade holder, facilitating quick assembly and disassembly.

[0019] Secondly, in this invention, the floating ring is located in the inner cavity of the groove, but the top of the floating ring is fixedly connected to the blade body. The floating ring and the blade body are an integral whole, and a first spring is provided at the bottom of the floating ring. The floating ring is also restricted in the inner cavity of the groove. Therefore, during the shaving process, the blade body continuously squeezes the first spring through the floating ring to deform it, which can achieve the effect of free floating.

[0029] 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.

[0030] Please see Figures 1-8 In this embodiment of the invention, a floating blade structure for an electric shaver includes: a shaver head 1; a disassembly / assembly mechanism 3 is installed on the top of the inner cavity of the shaver head 1; the disassembly / assembly mechanism 3 includes a shaver head housing 301 and a first sliding groove 304; a fixing shell 314 is fixedly connected to the front end of the top of the inner cavity of the shaver head housing 301; a second round rod 323 is fixedly connected to the inner cavity of the fixing shell 314; a second spring 308 is sleeved on the middle end of the outer surface of the second round rod 323; and second springs 308 are movably connected to the left and right sides of the outer surface of the second round rod 323. The rear end of the slider 316 and the second slider 316 are fixedly connected to the connecting rod 309. The rear end of the outer side of the connecting rod 309 is fixedly connected to the connecting block 311. The inner surface of the connecting block 311 is provided with a second sliding groove 305. The inner cavity of the second sliding groove 305 is fixedly connected to the first round rod 322. The outer side of the outer surface of the first round rod 322 is movably connected to the third slider 319. The outer surface of the first round rod 322 is sleeved with a third spring 315. The front end of the third slider 319 is fixedly connected to the first limiting plate 310.

[0031] The inner side of the first slide groove 304 is movably connected to the first slider 306. The top of the first slider 306 is fixedly connected to the second limiting plate 317. The middle of the top of the second limiting plate 317 is movably connected to two second movable rods 324. The four corners of the top of the inner cavity of the cutter head shell 301 are provided with third slide grooves 313.

[0032] In this invention, the blade holder body 201 is first positioned downwards, with the top edge of the blade holder 202 aligned with the inner sides of the first limiting plate 310 and the second limiting plate 317. The blade holder 202 is then pressed downwards, causing the edge of the blade holder 202 to press the first limiting plate 310 and the second limiting plate 317 outwards. When the first movable rod 303 moves outwards, it stretches the fourth spring 321, causing it to deform. After the blade holder 202 is inserted into the placement groove 312, the fourth spring 321 and the fourth spring 32... 1. After the pressure is lost, the device quickly resets, causing the first limiting plate 310 and the second limiting plate 317 to reset and lock the knife holder 202. During disassembly, simply press the connecting plate 307 inward. The connecting plate 307 drives the second slider 316 to move inward, compressing the second spring 308 and causing it to deform. The second slider 316 drives the connecting block 311 to move inward through the connecting rod 309, causing the first limiting plate 310 to move inward and release the limitation on the knife holder 202, making it convenient for people to quickly disassemble and assemble.

[0033] Specifically, a blade mesh mechanism 2 is installed on the inner surface of the razor head 1. The blade mesh mechanism 2 includes a through hole 302, which is circular, and a placement groove 312 is provided on the inner side of each through hole 302.

[0034] Specifically, a knife mesh holder 202 is placed in the inner cavity of the placement groove 312. The knife mesh holder 202 is circular, and the top edge of the knife mesh holder 202 contacts the inner surface of the placement groove 312.

[0035] Specifically, the top of the blade holder 202 is provided with a groove 205, which is annular, and the bottom of the inner cavity of the groove 205 is fixedly connected with a first spring 206.

[0036] Specifically, there are seven first springs 206 in the inner cavity of the groove 205, and the first springs 206 are distributed in an equal-distance ring in the inner cavity of the groove 205. The top of each first spring 206 is fixedly connected to a floating ring 204.

[0037] Specifically, the top of each floating ring 204 is fixedly connected to a blade mesh body 201, and the top of each blade mesh body 201 is provided with a ring of mesh 203. The blade mesh body 201 is made of stainless steel.

[0038] Specifically, the bottom of each of the second sliders 316 is fixedly connected to a connecting plate 307, and the connecting plates 307 are arranged symmetrically.

[0039] Specifically, the rear end of the inner cavity of the second slide groove 305 is provided with a second limiting groove 320, the rear end of the third slider 319 is movably connected to the outer side of the inner cavity of the second limiting groove 320, and the front side of the connecting block 311 is provided with a first limiting groove 318.

[0040] Specifically, the front and rear ends of the bottom of the cutter head housing 301 are fixedly connected with locking blocks 4, and the locking blocks 4 are symmetrically arranged and made of nylon.

[0041] In this invention, the floating ring 204 is located in the inner cavity of the groove 205, but the top of the floating ring 204 is fixedly connected to the foil body 201. The floating ring 204 and the foil body 201 are an integral unit, and a first spring 206 is provided at the bottom of the floating ring 204. The floating ring 204 is also restricted in the inner cavity of the groove 205. Therefore, during the shaving process, the foil body 201 continuously squeezes the first spring 206 through the floating ring 204 to deform it, which can achieve the effect of free floating.

[0042] The working principle of this invention is as follows: When installation is required, the bottom of the blade housing 301 faces upward, the blade holder 202 is held with the blade body 201 facing downward, and the top edge of the blade holder 202 is aligned with the inner side of the first limiting plate 310 and the second limiting plate 317. The blade holder 202 is pressed downward, at which point the edge of the blade holder 202 pushes the first limiting plate 310 and the second limiting plate 317 outward. The second limiting plate 317 drives the first slider 306 to slide outward in the inner cavity of the first sliding groove 304. The first slider 306 drives the second movable rod 324 to move to the left, and the second movable rod 324 drives the first movable rod 303 to move to the left, causing the first movable rod 303 to slide outward in the inner cavity of the third sliding groove 313. Since the two first movable rods 303 are connected by a fourth spring 321, when the first movable rod 303 moves outward, it stretches the fourth spring 321, causing it to deform. At the same time, the first limiting plate 302... The positioning plate 310 drives the third slider 319 to slide outward in the inner cavity of the second groove 305. While sliding on the outer surface of the second round rod 323, the third slider 319 compresses the fourth spring 321, causing it to deform. The inner top edges of the first limiting plate 310 and the second limiting plate 317 are arc-shaped, making it easy to press the knife mesh seat 202 in. After the knife mesh seat 202 is inserted into the placement groove 312, the fourth spring 321 and the second limiting plate 317 quickly reset after losing pressure, causing the first limiting plate 310 and the second limiting plate 317 to reset and lock the knife mesh seat 202. When it is necessary to remove the knife mesh seat 202, people only need to press the connecting plate 307 inward. The connecting plate 307 drives the second slider 316 to move inward, compressing the second spring 308 and causing it to deform. The second slider 316 drives the connecting block 311 to move inward through the connecting rod 309, causing the first limiting plate 310 to move inward and release the limitation on the knife mesh seat 202.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
