Description

Technical Field

[0001] This application relates to the field of personal care device technology, specifically to a razor. Background Technology

[0002] Current razors typically only have a single shaving function, cutting hair through the reciprocating motion of the blades, but they cannot provide aftercare for the shaved skin. Some razors have UV sterilization functions, such as Chinese Patent Publication No. CN202420779215.7, which uses a germicidal lamp on the top cover to sterilize the blade head, focusing on equipment hygiene maintenance, but it does not provide phototherapy for the skin in the shaved area, and cannot solve problems such as skin irritation (such as redness, swelling, and itching) during shaving; if phototherapy is to be provided, a separate phototherapy device is required, resulting in multiple devices and complicated operation for shaving and skin care. On the other hand, the blade head of current razors has low freedom of movement, resulting in insufficient shaving contour. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a razor that solves the problem that existing razors have only one function and cannot combine shaving and phototherapy functions.

Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0038] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0039] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0040] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0041] Please refer to Figure 1-6 As shown, the shaver 100 of this application embodiment generally includes a main body 1 and a blade head 2. The two are connected by a ball-type connector 3 to achieve multi-directional or non-directional movement of the blade head 2 relative to the main body 1, such as rotation or oscillation. Through the ball-type connector, the blade head 2 can rotate or oscillate in a variable direction within a 350° angle range. The blade head 2 includes a blade head housing 21 and several sets of blade assemblies 22, a light source assembly 23, and a vibrating plate 24 installed in the cavity of the housing. The light source assembly 23 includes a light source, and the light emitted directly by the light source or the light filtered by the light filter element has the effect of treating the skin, preferably near-infrared light. The main functions and features of the shaver 100 of this application are as follows: 1) Dual-function integration: The blade assembly 22 mechanically removes hair, while the light source assembly 23 generates light of a predetermined wavelength (such as near-infrared light) to irradiate the shaved area, thus realizing the dual functions of "shaving + phototherapy" in one machine. Of course, one function can also be selected to be activated. 2) Flexible blade head design: The blade head 2 is connected to the main body 1 through the ball joint 3, realizing multi-directional (non-directional) movement, and can rotate and swing, ensuring that the blade head 2 can conform to the skin curvature of different parts; 3) Precise optical path design: After the light source component 23 is reflected by the reflector 232, the light is emitted in the same direction. The light is filtered by the filter element 233 to ensure that the light of the predetermined wavelength (preferably the near-infrared wavelength) is efficiently applied to the shaving area.

[0042] The main body 1 includes a housing 11, within which a control circuit board 12 and a power module 13 are installed. The housing 11 primarily protects the internal components, provides a gripping structure, and supports the movement of the cutter head 2. A through hole 16 is provided at the top of the main body 1, communicating with the internal cavity, for mounting the ball-type connector 3 and the motor 15.

[0043] The main housing 11 can be a long, hollow structure (not limited to a long strip), with a protruding post 111 on the inner top wall (for fixing the damping block 32); the circular through hole 16 is opened at the top. The main housing 11 can be formed by fastening together a left outer shell 11a and a right outer shell 11b. The ball-head connector 3 and the motor 15 are located inside the main housing 11 near the top; the control circuit board 12 and the power module 13 are located in the cavity and below the ball-head connector 3. The light source 231, power module 13, button module 14, and motor 15 of the light source assembly 23 are electrically connected to the control circuit board 12.

[0044] The control circuit board 12 can be a PCBA board, which integrates functional circuits such as a controller, motor drive circuit, and light source control circuit. The power module 13, button module 14, motor 15, and light source assembly 23 can be electrically connected to the control circuit board 12 via wires. The control circuit board 12 can control the start / stop and speed of the motor 15, and the on / off and brightness of the light source 231 by receiving commands from the button module.

[0045] The power module 13 includes a battery 130 and / or an AC / DC conversion module (not shown), and is also equipped with a power interface (such as a Micro-USB) 131. The power interface 131 is located on the control circuit board 12 and its end passes through a through-hole in the housing 11 to expose the housing outside, facilitating connection to mains power or other power sources for powering the shaver 100 or charging the battery 130. Of course, the battery can be a primary battery or a rechargeable battery.

[0046] The button module 14 is mounted on or electrically connected to the control circuit board 12, and its outer side is exposed outside the housing 11 through a through hole for easy user operation. The button module 14 includes a power button and may also include a mode button, etc., and is embedded in the outer surface of the main housing 11. The power button controls the start and stop of the entire machine, and the mode button can be used to set and switch between modes such as "shaving", "shaving + light therapy", and "light therapy".

[0047] The ball-type connector 3 enables the movable connection between the cutter head 2 and the main body 1, and includes a ball head 31 and a damping block 32. The ball head 31 is a hollow shell, such as a sphere, hemisphere, or quasi-sphere, and the size or shape of the spherical surface of the ball head 31 is adapted to the required range and amplitude of the cutter head's movement (swinging and rotation). The ball head 31 has a hollow cavity inside, with several through holes, including a top through hole 311 for the top of the motor 15 and its top output end 151 to pass through, a side through hole 312 for the power supply line 314 to pass through, and a bottom through hole as a shaft hole (or a convex shaft) 313 to form a rotatable connection with the damping block 32. The ball head 31 is installed in the top through hole 16 of the main body shell 11, and its bottom is movably engaged with the damping block 32; the internal cavity of the ball head 31 accommodates and supports the motor 15, and achieves rotation and swaying through its engagement with the damping block 32.

[0048] The damping block 32 is block-shaped, with a convex shaft (or shaft hole) 321 at the top that is movably connected (for rotation and swing) to the shaft hole (or convex shaft) 313 at the bottom of the ball head 31. Several mounting holes 322 (e.g., a pair of mounting holes 322) are provided on the side of the damping block 32, which are inserted and tightly fitted with the protrusions 111 (a pair of protrusions 111) on the inner wall of the main body housing 11, thereby fixing the damping block 32 in the internal cavity of the main body housing and near the top.

[0049] The damping block 32 provides damping force to the ball head 31, allowing the cutter head 2 to remain stably at any angle (rotation and oscillation). It can also absorb the vibration of the motor inside the ball head 31, reducing the impact of motor vibration on the control circuit board 12 and the power module 13.

[0050] Motor 15 is preferably an eccentric motor or a vibration motor. Its output end 151 is connected to the cutter head 2, specifically, it is securely connected to the vibratory feeder 24 of the cutter head 2. The blade assembly 22 is mounted on the vibratory feeder 24. The output end 151 of motor 15 drives the vibratory feeder 24 to reciprocate, thereby driving the blade assembly 22 to reciprocate. Motor 15 is installed in the internal cavity of ball head 31 and is electrically connected to control circuit board 12. Its output end 151 passes through the top through hole 311 of ball head 31 and the bottom through hole 211 of cutter head housing 21 and connects to vibratory feeder 24. Motor 15 converts electrical energy into mechanical vibration, driving vibratory feeder 24 and blade assembly 22 to reciprocate. The reciprocating motion of vibratory feeder 24 and blade assembly 22 drives the entire cutter head to move synchronously.

[0051] The blade head 2 is the core component for performing shaving and (near-infrared) light therapy. It includes a blade head housing 21, which is formed by a top cover 21a and a base 21b fastening together, creating an internal cavity. For example, the top end face of the blade head 2 forms a light-emitting panel 212, which is positioned close to the skin in the shaving area during operation. The light-emitting panel 212 has three elongated (but not limited to) slots 213 that communicate with the internal cavity. The middle slot is the light outlet 213a, and the two side slots are blade assembly mounting slots 213b; the arrangement of the slots 213 is not limited to this. A through hole 211 is formed at the bottom of the base 21b, through which the top and output end 151 of the motor 15 pass. The blade head housing 21 engages with the output end 151 of the motor 15 via the bottom through hole 211, and the internal cavity accommodates the vibrating plate 24, the blade assembly 22, and the light source assembly 23. The blade housing 21 is used to mount the blade assembly 22 and the light source assembly 23. A slot 213 in the light-emitting panel 212 guides hair into the blade assembly 22, and a light-emitting port 213a allows light to penetrate and irradiate the skin. In a non-limiting example, there are four sets of blade assemblies 22 (not limited to four sets), symmetrically distributed on both sides of the light-emitting port 213a (this arrangement is not limited to this). Each set of blade assemblies 22 includes a blade holder 221, which can be designed as a lever structure with a central axis (axis hole) 221a, a bottom support leg 221b, and a slot 221c formed along the length of the top. The blade 222 can be made of stainless steel, has an arc-shaped surface, and a row of arc-shaped cutting edges 222a along its length. The blade mesh 223 can be made of metal, with etched mesh holes on the surface, and its shape is adapted to the blade 222. The blade 222 is engaged in the slot 221c of the blade holder 221, and the blade mesh 223 is attached to the outside of the blade 222 and secured together in the slot 221c. The blade holder 221 is connected to the top short shaft 241 of the vibratory feeder 24 via a bottom shaft hole (or shaft center) 221a. Therefore, the motor 15 drives the vibratory feeder 24 to reciprocate the blade holder 221, and the blade 222 reciprocates synchronously. The reciprocating motion of the blade 222 cuts the hair that enters the blade mesh 223, which prevents the skin from directly contacting the blade, reducing irritation.

[0052] The vibratory feeder 24 can be a flat plate, with its bottom fixedly connected to the output end 151 of the motor 15 (possibly through an insertion fit between a convex shaft and a shaft hole). Two (or one or more) platforms can be provided on the top, forming a stepped shape. The platforms are spaced apart, with a light source assembly 23 installed above the middle gap. Each platform has an upward-extending short shaft 241 (e.g., two symmetrically arranged short shafts 241) that respectively mate with two blade holders 221. The vibratory feeder 24 is installed inside the cavity of the blade housing 21, with its bottom connected to the output end 151 of the motor 15, and its top short shafts 241 connected to the axis 221a of the blade holder 221. The vibratory feeder 24 transmits the vibration of the motor 15 to the blade assembly 22, driving the blade 222 to reciprocate.

[0053] The light source assembly 23 includes a light source 231, a reflector 232, and a filter element 233 or a light-transmitting plate 234. The light source 231 is mounted behind the light outlet 213a; the reflector 232 is fixed to the outside of the light source 231, and may be arc-shaped, wrapping around the outside of the light source 231. The filter element 233 or the light-transmitting plate 234 covers the light outlet and encloses the light source 231 inside the reflector 232. The light source 231 can be an incandescent lamp, preferably a halogen lamp, a carbon filament lamp, or a tungsten filament lamp, or other light sources. The reflector 232 and its inner surface have reflective properties, reflecting the light emitted by the light source towards the light outlet 213a. The optical filter element 233 can be a filter or filter film, preferably with filtering characteristics including the near-infrared band (e.g., 750-2500nm). The light-transmitting plate 234 is made of a transparent material, such as a transparent plastic sheet or a transparent crystal.

[0054] In some embodiments, the filter element 233 may be disposed on and cover the light outlet 213a, or disposed between the light source 231 and the light outlet 213a, or disposed on the inner or outer surface of the light source 231 lamp tube, or disposed on the outer surface or outside of the light-transmitting plate 234. The light waves emitted by the light source 231 are filtered by the filter element 233 to obtain near-infrared light, which is applied to the skin of the shaved area for near-infrared skin treatment. The light source 231 emits light, which is reflected by the reflector 232 and filtered by the filter element 233. Light of a predetermined wavelength (such as near-infrared light) is emitted from the light outlet 213a and irradiates the shaved area.

[0055] The shaver 100 of this application is connected to the main body 1 and the shaver head 2 as follows: the shaver head 2 is connected to the main body 1 through a ball joint connector 3—the ball joint 31 is installed in the top through hole 16 of the main body housing 11, the damping block 32 fixes the inner wall of the main body housing 11 and supports the ball joint 31, and the motor 15 is installed inside the ball joint 31, with its output end 151 connected to the vibrating plate 24 of the shaver head 2. The motor 15 is located in the neck of the shaver body, with its upper part located inside the shaver head 2 (bottom) and its lower part located inside the main body 1 (top).

[0056] Inside the cutter head 2, the vibratory feeder 24 connects the motor 15 and the blade assembly 22. The light source assembly 23 is fixed inside the cutter head housing 21, specifically behind the light emission panel 212, and specifically behind the corresponding light emission port 213a. For example, the top surface of the cutter head housing 21 (or other end surfaces such as the side) serves as the light emission panel 212.

[0057] The control circuit board 12 is connected to the power module 13 (battery 130 and power interface 131), button module 14, motor 15 and light source 231 via wires or circuits. The wire 314 passes through the through hole 312 of the ball head 31 and is connected to the motor 15. It can also enter the cutter head through the through hole 16 at the top of the main body housing 11 and the through hole 211 at the bottom of the cutter head housing 21 and be electrically connected to the light source 231.

[0058] The working principle of the razor 100 in this application: 1) Shaving function: The power button on the operation button 14 starts the motor 15 on the control circuit board 12. The output end 151 of the motor 15 drives the vibratory plate 24 to vibrate at high frequency. The vibratory plate 24 drives the blade assembly 22 to reciprocate synchronously through the top short shaft 241. The arc-shaped cutting edge 222a of the blade 222 cuts the hair that enters the blade mesh 223.

[0059] 2) Phototherapy, specifically near-infrared light therapy: Using the mode button on operation button 14, switch to the "Shaving + Light Therapy" mode. Control circuit board 12 activates light source 231. Light source 231 emits light, which is reflected by reflector 232 and emitted from light outlet 213a. The light emitted by the light source, or filtered by filter element 233, becomes light of a predetermined wavelength (such as near-infrared light). The predetermined wavelength (near-infrared light) shines through light outlet 213a onto the shaving area, providing anti-inflammatory and soothing treatment effects to the skin and hair follicles. During shaving, the near-infrared light from the lamp irradiates the shaving area, generating an internal heat effect that promotes hair follicle shrinkage and accelerates follicle aging, thus extending the hair growth cycle. Simultaneously, the near-infrared light effect accelerates blood circulation and increases metabolism, achieving anti-inflammatory and antibacterial effects and eliminating discomfort such as redness and itching after shaving. Existing technologies have confirmed the therapeutic efficacy of near-infrared light on the skin and hair follicles on its surface. This application will not repeat the clinical trials. This application applies near-infrared light technology to treat the skin in the shaving area and delay the hair growth cycle in a razor.

[0060] The operating principle of the razor head 2 in the razor 100 of this application is as follows: During shaving, the blade head 2 follows the curve of the skin, and the ball head 31 rotates or oscillates around the convex shaft 321 of the damping block 32. Thanks to the design of the ball head 31 in the ball-type connector 3, the blade head can rotate or oscillate in any direction within a 350° angle range. The damping block 32 can be made of a material with high damping force, such as silicone, to provide damping force, allowing the blade head 2 to remain stably in contact with the skin. The ball head 31 of the ball-type connector 3, in conjunction with the damping block 32, allows the blade head 2 to oscillate and rotate, increasing the freedom of the blade head 2, making it more adaptable to the shape of the shaving area, and allowing the blade head 2 to better conform to the skin.

[0061] The razor 100 of this application has the following characteristics: 1) When shaving, the near-infrared rays emitted by the lamp (or the near-infrared rays obtained after filtering) can irradiate the shaving area to produce an internal heat effect, which accelerates the aging of hair follicles. That is, while shaving off the hair on the outside of the skin, it also causes the hair follicles under the skin to shrink, thereby promoting the extension of the hair growth cycle. At the same time, the near-infrared light effect accelerates blood circulation and promotes metabolism to achieve anti-inflammatory and bactericidal effects, eliminating discomfort such as redness, swelling and itching after shaving. 2) The ball-head design of the connector increases the freedom of the shaving head, the swingable design makes it fit the skin better, and the rotating design makes it more adaptable to the shaving needs of different areas.

[0062] It is understood that in other embodiments, the light source assembly 2 of the razor can use a light source 231 that emits light of other wavelengths, combined with a suitable filter element, to obtain emitted light of a predetermined wavelength that acts on the shaving area. The light generated by the light source or the light generated after being filtered by the filter element has different effective effects on the skin depending on its photon wavelength. For example, 480nm photons have a bactericidal and disinfecting function, 530nm photons can rejuvenate the skin and lighten pigmentation, 600nm photons can soften blood vessels, and 640nm photons can remove hair. In some embodiments, the light generated by the light source 231 or the light wave after being filtered by the filter element can have one or more of the following wavelengths: The 430-1200nm wavelength range can be used to treat inflammatory acne; The 480-1200nm wavelength range can be used to treat acne and vascular lesions; The 530-1200nm wavelength range can be used to treat vascular (superficial small blood vessels) and pigmented lesions; The 560-1200nm wavelength can be used for wrinkle removal and treatment of pigmented and vascular lesions (deep and thick blood vessels). The 640-1200nm wavelength range can be used for hair removal, skin rejuvenation, and deep redness reduction. The 690-1200nm wavelength can be used for hair removal, deep redness removal, etc. The light source and filter characteristics of the filter element can be configured according to specific application needs.

[0063] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
