Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of personal care appliances, and more particularly to razors. [Background technology]

[0002] Conventional razors generally only have a single shaving function—cutting hair with the reciprocating motion of the blade—and do not provide post-shaving skin care. As disclosed in Chinese Utility Model Application No. 202420779215.7, some shaving devices are equipped with a UV disinfection function, which uses a germicidal lamp attached to the top cover to sterilize the razor head, emphasizing hygiene maintenance of the device. However, these do not provide phototherapy for the skin in the shaved area and cannot address issues such as skin irritation during shaving (e.g., redness, swelling, itching, etc.). If phototherapy is required, a separate phototherapy device must be used, and the multiple devices required for shaving and skin care make operation complicated. Meanwhile, conventional razors have limited freedom of movement of the razor head and an inadequate shaving fit. Summary of the Invention [Problem to be solved by the invention]

[0039] As shown in FIGS. 1 to 6, a razor 100 according to an embodiment of the present application generally comprises a main body 1 and a razor head 2. The two are connected to the main body 1 via a ball-joint-type connecting member 3, allowing the razor head 2 to be rotatably or oscillate in multiple directions or in any direction, for example, rotatably or oscillatably. The ball-joint-type connecting member allows the razor head 2 to rotate or oscillate in any direction within an angular range of 350°.

The light source assembly 23 includes a light source, and light emitted directly from the light source or light filtered by a filter element has a skin treatment effect, preferably near-infrared light. The main functions and features of the razor 100 according to the present application are as follows:

[0040] 1) Dual function integration: The blade assembly 22 mechanically shaves hair, while the light source assembly 23 generates light in a specific wavelength band (e.g., near-infrared light) to illuminate the shaving area, thereby achieving the dual functions of "shaving + phototherapy" in one device, and of course, either function can be turned on.

[0041] 2) Flexible razor head design: The razor head 2 is connected to the main body 1 via a ball-joint type connecting member 3, allowing it to rotate and swing in multiple directions (non-directionally), ensuring that the razor head 2 can fit the curves of the skin in various areas.

[0042] 3) Precise optical path design: After being reflected by the light reflecting member 232, the light source assembly 23 emits light in the same light emission direction, and the filter element 233 selects the wavelength band, ensuring that light in a predetermined wavelength band (preferably the near-infrared wavelength band) acts efficiently on the shaving area.

[0043] Here, main body 1 includes housing 11, and a control circuit board 12 and a power supply module 13 are mounted within the internal cavity of main body housing 11. Main body housing 11 mainly protects the internal elements and provides a grip structure to support the movement of razor head 2. A through hole 16 communicating with the internal cavity is provided at the top of main body 1, and is used to mount ball-joint type connecting member 3 and motor 15.

[0044] The main body housing 11 is a long (but not limited to long) hollow structure, and may have a protruding post 111 (used to secure the damping block 32) on the inner wall at the top, and a circular through-hole 16 at the top. The main body housing 11 may be formed by engaging a left housing 11a with a right housing 11b. The ball joint-type connecting member 3 and the motor 15 are located inside the main body housing 11 near the top, and the control circuit board 12 and power supply module 13 are located in the cavity and below the ball joint-type connecting member 3. The light source 231, power supply module 13, key module 14, and motor 15 of the light source assembly 23 are electrically connected to the control circuit board 12.

[0045] The control circuit board 12 may be a PCBA board on which functional circuits such as a controller, a motor driving circuit, and a light source control circuit are integrated. The power supply module 13, the key module 14, the motor 15, and the light source assembly 23 may be electrically connected to the control circuit board 12 via electrical wires. The control circuit board 12 can receive commands from the key module and control the start / stop and rotation speed of the motor 15, the opening / closing and brightness of the light source 231, etc.

[0046] The power supply module 13 includes a battery 130 and / or an AC / DC converter module (not shown), and also has a power interface (e.g., Micro-USB) 131. The power interface 131 is disposed on the control circuit board 12, and its end passes through a through-hole on the housing 11 and is exposed to the outside of the housing, facilitating connection to a commercial power source or other power source for supplying power to the razor 100 or charging the battery 130. Of course, the battery may be a primary battery or a rechargeable battery.

[0047] The key module 14 is disposed on the control circuit board 12 or electrically connected to the control circuit board 12, and its outer surface is exposed to the outside of the housing 11 through a through-hole provided on the housing 11 to facilitate user operation. The key module 14 includes a power key and may also include a mode key, etc. The key module is embedded in the outer surface of the housing 11 of the main body. The power key controls starting / stopping the entire device, and the mode key can be used to switch between modes such as "shaving," "shaving + light therapy," and "light therapy."

[0048] The ball joint-type connecting member 3 provides a movable connection between the razor head 2 and the main body 1 and includes a ball joint 31 and a damping block 32. The ball joint 31 is a spherical, hemispherical, or quasi-spherical hollow housing, and the size or shape of the spherical surface of the ball joint 31 is adapted to the required width and range of movement (oscillation and rotation) of the razor head. The interior of the ball joint 31 is hollow and is provided with a plurality of through-holes, including a through-hole 311 at the top through which the upper and upper output ends 151 of the motor 15 pass, a through-hole 312 at the side through which electric wires 314 pass, and a through-hole at the bottom as a shaft hole (or protruding shaft) 313 that forms a rotational connection with the damping block 32. The ball joint 31 is mounted in the through-hole 16 at the top of the housing 11 of the main body, and its bottom is movably fitted with the damping block 32. The internal cavity of the ball joint 31 accommodates and supports the motor 15, which cooperates with the damping block 32 to realize rotation and oscillation.

[0049] The damping block 32 is block-shaped and has a protruding shaft (or shaft hole) 321 at the top, which forms a movable connection (rotation and swing) with the shaft hole (or protruding shaft) 313 at the bottom of the ball joint 31. Da The side of the damping block 32 has a plurality of assembly holes 322 (for example, a pair of assembly holes 322), into which the protruding posts 111 (a pair of protruding posts 111) on the inner wall of the main body housing 11 are inserted to form an interference fit, thereby fixing the damping block 32 within the internal cavity of the main body housing near the upper part.

[0050] The damping block 32 applies a damping force to the ball joint 31, allowing the razor head 2 to stably stop (rotate and swing) at any angle, and also absorbs the vibrations of the motor within the ball joint 31, reducing the impact of the motor vibrations on the control circuit board 12 and power supply module 13.

[0051] The motor 15 is preferably an eccentric motor or a vibration motor, and its output end 151 is connected to the razor head 2, specifically, fastened to the vibration platen 24 of the razor head 2, the blade assembly 22 is mounted on the vibration platen 24, and the output end 151 of the motor 15 is connected to the vibration platen 24 to drive the vibration platen 24 to reciprocate, thereby driving the blade assembly 22 to reciprocate. The motor 15 is mounted in the inner cavity of the ball joint 31 and electrically connected to the control circuit board 12, and the output end 151 is connected to the vibration platen 24 through a through-hole 311 at the top of the ball joint 31 and a through-hole 211 at the bottom of the razor head housing 21. The motor 15 converts electrical energy into mechanical vibrations, driving the vibration platen 24 and the blade assembly 22 to reciprocate. The reciprocating motion of the vibration platen 24 and the blade assembly 22 drives the entire razor head to move synchronously.

[0052] The razor head 2 is the core of the razor for performing shaving and (near-infrared) light treatment, and includes a razor head housing 21, with its upper cover 21a and base 21b mated to form an internal cavity. For example, the upper end surface of the razor head 2 forms a light-emitting panel 212, which comes into close proximity with the skin of the area to be shaved during operation. The light-emitting panel 212 is provided with three elongated (but not limited to elongated) through-grooves 213 communicating with the internal cavity, with the central through-groove being a light outlet 213a and both sides being blade assembly mounting grooves 213b, although the arrangement of the through-grooves 213 is not limited thereto. A through-hole 211 is provided at the bottom of the base 21b to allow the upper part and output end 151 of the motor 15 to pass through. The razor head housing 21 is fitted to the output end 151 of the motor 15 via a through-hole 211 at its bottom, and the internal cavity accommodates the vibration plate 24, the blade assembly 22, and the light source assembly 23. The razor head housing 21 is used to mount the blade assembly 22 and the light source assembly 23. The through-hole 213 of the light output panel 212 guides hair into the blade assembly 22, and the light passing through the light outlet 213a is irradiated onto the skin. As a non-limiting example, there are four sets of blade assemblies 22 (not limited to four sets), which are symmetrically distributed on both sides of the light outlet 213a (not limited to this arrangement). Each set of blade assemblies 22 is equipped with a blade holder 221, which may be designed in a lever structure, with an axis (axis hole) 221a in the middle, support legs 221b at the bottom, and an engagement groove 221c formed along the length at the top. Blade 222 may be made of stainless steel with an arcuate surface, with arcuate cutting edges 222a arranged in a row along its length. Mesh blade 223 may be made of metal with a mesh etched on its surface, with a shape that matches blade 222. Blade 222 is engaged in engagement groove 221c of blade holder 221, and mesh blade 223 is attached to the outside of blade 222 and engaged with engagement groove 221c. Blade holder 221 is inserted and fitted onto short shaft 241 at the top of vibrating plate 24 via shaft hole (or shaft center) 221a at its bottom, so that motor 15 drives vibrating plate 24 to drive blade holder 221 to reciprocate, causing blade 222 to reciprocate in sync.The blade 222 moves back and forth to cut hair that has entered the mesh blade 223, and the mesh blade 223 prevents the skin from coming into direct contact with the blade, reducing irritation.

[0053] The vibrating plate 24 may be a flat plate, the bottom of which is fixedly connected to the output end 151 of the motor 15 (it may be connected by inserting a protruding shaft and a shaft hole), and two (or one or more) platforms are provided on the top to form the vibrating plate 24 in a stepped shape, with the platforms spaced apart from each other and the light source assembly 23 attached above the middle space, and each platform is provided with a short shaft 241 extending upward. ( For example, two short axes 241 are provided symmetrically. ) , each fitted to two blade holders 221 。 The vibrating platen 24 is attached to the internal cavity of the razor head housing 21, with its bottom connected to the output end 151 of the motor 15 and its upper short shaft 241 connected to the axis 221a of the blade holder 221. The vibrating platen 24 transmits the vibration of the motor 15 to the blade assembly 22, driving the blade 222 to reciprocate.

[0054] The light source assembly 23 includes a light source 231, a light-reflecting member 232, and a filter element 233 or a light-transmitting plate 234. The light source 231 is attached to the rear side of the light outlet 213a, and the light-reflecting member 232 is fixed to the outside of the light source 231 and may be arc-shaped so as to surround the outside of the light source 231. The filter element 233 or the light-transmitting plate 234 covers the light outlet and covers the light source 231 on the inside of the light-reflecting member 232. The light source 231 may be an incandescent lamp, or preferably a halogen lamp, carbon filament lamp, tungsten filament lamp, or other light source. The light-reflecting member 232 and its inner surface have light-reflecting properties and reflect light emitted from the light source toward the light outlet 213a. The optical filter element 233 may be a filter or filter film, and preferably has filter properties including a near-infrared band (e.g., 750 to 2500 nm). The light-transmitting plate 234 is made of a transparent material such as a transparent plastic plate or transparent crystal.

[0055] In some embodiments, the filter element 233 may be disposed on the light outlet 213a to cover the light outlet, or may be disposed between the light source 231 and the light outlet 213a, or on the inner or outer surface of the lamp tube of the light source 231, or on the outer or outer surface of the light-transmitting plate 234. The light waves emitted from the light source 231 are filtered by the filter element 233 to obtain near-infrared light, which acts on the skin of the shaving area to perform near-infrared treatment of the skin. The light emitted from the light source 231 is reflected by the light reflecting member 232 and screened by the filter element 233, after which light of a predetermined wavelength band (e.g., near-infrared light) is emitted from the light outlet 213a and irradiated onto the shaving area.

[0056] In the razor 100 of the present application, the main body 1 and the razor head 2 are connected via a ball joint type connecting member 3. That is, a ball joint 31 is attached to the through hole 16 in the upper part of the housing 11 of the main body, a damping block 32 is fixed to the inner wall of the housing 11 of the main body to support the ball joint 31, and a motor 15 is attached within the ball joint 31, with its output end 151 connected to the vibrating plate 24 of the razor head 2. The motor 15 is located within the neck portion of the entire razor, with its upper part located within the razor head 2 (bottom part) and its lower part located within the main body 1 (upper part).

[0057] Inside the razor head 2, the vibrating plate 24 connects the motor 15 and the blade assembly 22, and the light source assembly 23 is fixed within the razor head housing 21. Specifically, it is attached to the rear side of the light emitting panel 212, and specifically, is located on the rear side corresponding to the light outlet 213a. For example, the top end surface of the razor head housing 21 (or another end surface such as a side surface) may function as the light emitting panel 212.

[0058] The control circuit board 12 is connected to a power supply module 13 (power supply) via an electric wire or circuit. pond130 and energizing interface 131), are connected to key module 14, motor 15 and light source 231, and electrical wire 314 passes through through-hole 312 of ball joint 31 to connect to motor 15, and is further electrically connected to light source 231 within the razor head via through-hole 16 at the top of main body housing 11 and through-hole 211 at the bottom of razor head housing 21.

[0059] The operating principle of the razor 100 of the present application is as follows.

[0060] 1) Shaving function: When the power key of the key 14 is operated, the control circuit board 12 starts the motor 15, and the output end 151 of the motor 15 drives the vibrating plate 24 to vibrate at high frequency, and the vibrating plate 24 drives the blade assembly 22 to reciprocate synchronously via the upper short shaft 241, and the arc-shaped cutting edge 222a of the blade 222 cuts the hair that has entered the mesh blade 223.

[0061] 2) Light therapy, i.e. near-infrared light therapy function: When the mode key on the keypad 14 is operated to switch to the "Shaving + Light Therapy" mode, the control circuit board 12 activates the light source 231, which emits light. The light is reflected by the light-reflecting member 232 and emitted from the light outlet 213a. The light emitted from the light source or filtered by the filter element 233 is converted into light of a predetermined wavelength band (e.g., near-infrared light). The light of the predetermined wavelength band (near-infrared light) passes through the light outlet 213a and is irradiated onto the shaving area, providing therapeutic effects such as anti-inflammatory and soothing effects on the skin and hair follicles. During shaving, the near-infrared light from the lamp tube is irradiated onto the shaving area, generating an internal heating effect that promotes the contraction of hair follicles in the shaving area, accelerating hair follicle aging and lengthening the hair growth cycle. The near-infrared light also accelerates blood circulation, increases metabolism, and exerts anti-inflammatory and antibacterial effects, eliminating discomfort such as redness, swelling, and itching after shaving. The therapeutic effect of near-infrared light on the skin and its superficial hair follicles has been demonstrated in the prior art, and rather than repeating clinical trials, this application applies near-infrared light technology to a razor to provide therapeutic treatment to the skin in the shaved area. and prolong the hair growth cycle That is the thing.

[0062] In the razor 100 of the present application, the operating principle of the razor head 2 is as follows.

[0063] During shaving, the razor head 2 is subjected to a force along the curved surface of the skin, causing the ball joint 31 to rotate or swing around the protruding axis 321 of the damping block 32. The design of the ball joint 31 of the ball joint-type connecting member 3 allows the razor head to rotate or swing in any direction within an angular range of 350°. The damping block 32 uses a material with high damping force, such as silicone, to provide a damping force, allowing the razor head 2 to remain stably in place after coming into contact with the skin. The ball joint 31 of the ball joint-type connecting member 3, in conjunction with the damping block 32, allows the razor head 2 to swing or rotate, increasing the degree of freedom of the razor head 2, allowing it to better adapt to the shape of the area being shaved and improving the adhesion of the razor head 2 to the skin.

[0064] The razor 100 of the present application has the following features:

[0065] 1) During shaving, near-infrared (or filtered near-infrared) rays emitted from the lamp tube are irradiated onto the shaving area, creating an internal heating effect that accelerates the aging of hair follicles. In other words, shaving the outer hairs of the skin simultaneously shrinks the hair follicles beneath the skin, achieving the goal of extending the hair growth cycle. At the same time, the near-infrared light effect accelerates blood circulation, increases metabolism, and exerts anti-inflammatory and antibacterial effects, eliminating discomfort such as redness, swelling, and itching after shaving.

[0066] 2) The ball joint design of the connecting member allows for greater freedom of movement of the razor head, the swingable design improves fit to the skin, and the rotatable design allows for improved adaptability to the shaving needs of various areas.

[0067] It will be appreciated that in other embodiments, the razor's light source assembly 23 can use a light source 231 that emits light in other wavelength bands, which, when combined with an appropriate filter element, can provide emitted light of a predetermined wavelength band to act on the shaving area. The light generated by the light source or the light generated after filtering by the filter element has different beneficial effects on the skin in different photon bands. For example, 480 nm photons have antibacterial and disinfecting effects, 530 nm photons have skin rejuvenation and blemish reduction effects, 600 nm photons have vascular softening effects, and 640 nm photons have hair removal effects. In some embodiments, the light generated by the light source 231 or the light waves generated after filtering by the filter element can have one or more of the following wavelength bands:

[0068] The wavelength band of 430 to 1200 nm can be used to treat inflammatory acne. The wavelength band of 480-1200 nm can be used to treat acne and vascular lesions. The wavelength band of 530-1200 nm can be used to treat vascular (superficial thin blood vessels) and pigmented lesions. The wavelength band of 560-1200nm can be used to remove wrinkles, treat pigmented lesions and vascular lesions (thick blood vessels in the deep layer). The wavelength range of 640~1200nm can be used for hair removal, skin rejuvenation, and deep redness removal. The wavelength range of 690-1200nm can be used for hair removal, deep redness removal, etc. The filtering characteristics of the light source and the filter element can be set according to the requirements of a particular application.

[0069] Although the embodiments of the present application have been shown and described above, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application, and the scope of protection of the present application is limited by the appended claims and their equivalents.
