Description

Technical Field

[0001] This utility model relates to the field of hair trimmer technology, and more specifically, to a shaving aid component and hair trimmer that are easy to disassemble and install. Background Technology

[0002] In the use of traditional razors, shaving aids can significantly improve shaving comfort and results. However, because shaving aids are gradually consumed over time, existing products typically use a design where the entire razor head is replaced, which not only increases user costs but also wastes resources. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a shaving aid assembly that is easy to disassemble and install, comprising a frame adapted for detachable connection to a shaving head, the frame being connected to a shaving aid; the frame is provided with a first limiting group and a second limiting group, the first limiting group and the second limiting group being spaced apart from each other; when the shaving head is installed in the frame, the shaving head is confined between the first limiting group and the second limiting group; when the frame needs to detach from the shaving head, the second limiting group is pushed to deform, causing the shaving head to detach from the constraint of the second limiting group, thereby separating the frame from the shaving head.

[0004] Optionally, the frame is connected to an elastic element, and the shaving aid is flipped and connected to the frame through the elastic element.

[0005] Optionally, the elastic elements are connected to the upper and lower sides of the frame, and each elastic element is connected to a shaving aid.

[0006] Optionally, the first limiting group includes a first limiting piece and a second limiting piece. The frame has an inner side surface. The first limiting piece and the second limiting piece are respectively disposed at the upper and lower ends of the inner side surface, and both the first limiting piece and the second limiting piece are located at the front end of the inner side surface. When the shaver head is installed in the frame, the front side surface of the shaver head abuts against the rear surface of the first limiting piece and the rear surface of the second limiting piece, respectively.

[0007] Optionally, the first limiting piece extends downward from the front end of the inner side, and the second limiting piece extends upward from the front end of the inner side; both the first limiting piece and the second limiting piece are flush with the front surface of the frame.

[0008] Optionally, when the shaver head is installed within the frame, the inner side surface abuts against the outer side wall of the shaver head circumferentially.

[0009] Optionally, the second limiting group includes a first latch and a second latch, both of which are located at the rear end of the frame and on the upper and lower sides of the frame, respectively. When the shaver head is installed in the frame, the rear side of the shaver head abuts against the front surface of the first latch and the front surface of the second latch, respectively. When the frame needs to detach from the shaver head, the first latch is pushed to deform so that the shaver head is released from the restriction of the first latch, thereby moving the shaver head to release it from the restriction of the second latch, thus achieving complete separation of the frame from the shaver head.

[0010] Optionally, the second limiting group is further provided with a pushing piece to facilitate force application, and the first fastener is located on the pushing piece.

[0011] Optionally, the second fastener includes two latches spaced apart from each other on the left and right.

[0012] Compared to existing technologies, the shaving aid component of this invention, which is easy to disassemble and install, features a detachable frame and front and rear limiting structures of the first and second limiting groups. This ensures the shaving head is stably positioned during use, guaranteeing a stable and reliable shaving effect. The second limiting group can deform under external force, enabling quick assembly and disassembly of the shaving head and frame. This simplifies operation and enhances user convenience and experience. When replacing the shaving aid, simply remove the frame from the shaving head; the shaving aid is removed along with the frame, eliminating the need to replace the entire shaving head. This ease of operation effectively reduces user costs, avoids resource waste caused by frequent head replacements, and improves the product's economic and environmental value.

[0013] In addition, this utility model provides a hair trimmer, including a shaving aid component that is easy to disassemble and install as described above.

[0014] Compared to existing technologies, the hair trimmer described in this utility model has the same advantages as the aforementioned easy-to-disassemble and install shaving aid component, which will not be repeated here. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0023] This utility model embodiment provides a shaving aid component that is easy to disassemble and install, combined with Figures 1 to 4 As shown, the device includes a frame 2 adapted for detachable connection with a shaving head 1, and a shaving aid 3 is connected to the frame 2. The frame 2 is provided with a first limiting group 21 and a second limiting group 22, which are spaced apart from each other. When the shaving head 1 is installed in the frame 2, the shaving head 1 is restricted between the first limiting group 21 and the second limiting group 22. When the frame 2 needs to detach from the shaving head 1, the second limiting group 22 is pushed to deform so that the shaving head 1 is released from the restriction of the second limiting group 22, thereby separating the frame 2 from the shaving head 1.

[0024] Among them, shaving aid 3 refers to a substance or material used in the shaving process to assist the razor in smoothly removing beard hairs and protecting the skin. Its main functions are to lubricate and soften beard hairs, reduce friction, prevent scratches and skin irritation, thereby improving shaving comfort and safety. Shaving aid 3 can be a gel-like or wax-like substance that releases lubricating ingredients such as aloe vera, vitamin E, and glycerin when it comes into contact with water. The frame 2 and shaving aid 3 are preferably connected in a movable manner. The movable connection between the frame 2 and shaving aid 3 is an elastic connection or a torsion spring hinge connection, which gives shaving aid 3 a certain degree of floating and cushioning ability during shaving. It can conform to the unevenness of the skin and avoid the pulling or jamming between shaving aid 3 and the skin during shaving, thereby improving smoothness and comfort.

[0025] The frame 2 is preferably made of plastic, such as engineering plastics like polypropylene (PP), polycarbonate (PC), or ABS, which have good molding performance, mechanical properties, and cost advantages. The first limiting group 21 and the second limiting group 22 are preferably integrally injection molded with the frame 2 to improve the stability of the overall structure, reduce assembly processes, and improve product consistency and production efficiency. The second limiting group 22, by utilizing the elasticity and deformability of the plastic material itself, can undergo controllable deformation when pushed by external force, thereby allowing the shaver head 1 to smoothly pass through the second limiting group 22 and detach from the frame 2, realizing the quick assembly or disassembly operation between the shaver head 1 and the frame 2.

[0026] In addition, the first limiting group 21 and the second limiting group 22 can also be formed by separate manufacturing and assembly with the frame 2. That is, the limiting group is an independent component and is fixed to the frame 2 by mechanical connection, snap-fit ​​2221 connection, welding or adhesive. The second limiting group 22 is made of plastic material, such as nylon, PP or elastic TPU, which has good deformation ability and resilience. In scenarios where deformation release is required, other materials with a certain degree of flexibility or elasticity can also be used, such as silicone, rubber or metal spring sheet covering structure. This separate structure not only facilitates the standardized and modular manufacturing of the limiting structure, but also facilitates flexible replacement or maintenance according to different cutter head specifications.

[0027] The first limiting group 21 is used to position and fix the shaver head 1 to prevent it from coming out at the front end. It can be a protrusion structure, a limiting edge, or an arc-shaped bracket structure (i.e., a partial arc-shaped protrusion that fits the contour of the shaver head 1). The second limiting group 22 is used for movable limiting and has deformation capability. It can undergo elastic deformation when subjected to force to release the shaver head 1, so as to realize assembly or disassembly. It can be an elastic hook, a claw structure, a spring, or a barbed limiting part.

[0028] When the shaver head 1 is installed inside the frame 2, the shaver head 1 is restricted between the first limiting group 21 and the second limiting group 22. The restriction can be achieved by the front side of the shaver head 1 abutting against the first limiting group 21 and the rear side abutting against the second limiting group 22. Alternatively, the restriction can be achieved by the clamping cooperation between the two sides of the shaver head 1 and the limiting group, or by the engagement, snapping, or sliding rail limiting of specific structural parts of the shaver head 1 with the limiting group. This ensures a stable installation and prevents the shaver head 1 from shifting or falling off during use.

[0029] The force that causes the second limiting group 22 to deform can be the user's fingers, which press or squeeze the exposed part of the second limiting group 22 to deform it outward and release the shaver head 1; or it can be an auxiliary tool, such as applying external force through a special disassembly tool or prying structure to achieve the force deformation of the second limiting group 22; this enhances the operability of the component and adapts to the usage habits or scenario needs of different users.

[0030] The easily detachable and installable shaving aid component in this embodiment, through the detachable frame 2 and the front and rear limiting structures of the first limiting group 21 and the second limiting group 22, ensures that the shaving head 1 can be stably positioned during use, ensuring a stable and reliable shaving effect. The second limiting group 22 can deform under external force, thereby realizing the quick assembly and disassembly of the shaving head 1 and the frame 2, which is simple to operate and improves the user's convenience and experience. When replacing the shaving aid 3, simply remove the frame 2 from the shaving head 1, and the shaving aid 3 will be removed along with the frame 2, without having to replace the entire shaving head 1. This simple operation can effectively reduce user costs, avoid resource waste caused by frequent head replacements, and improve the product's economic and environmental value.

[0031] Optionally, combined Figures 1 to 4 As shown, the frame 2 is connected to an elastic element 4, and the shaving aid 3 is flipped and connected to the frame 2 via the elastic element 4. The elastic element 4 can be a torsion spring, leaf spring, rubber, or flexible plastic, and is preferably located at the connection between the shaving aid 3 and the frame 2. The connection between the shaving aid 3 and the elastic element 4 forms a movable flipping structure, allowing the shaving aid 3 to flip relative to the frame 2 within a certain angle range. The elastic element 4 can be fixed between the frame 2 and the shaving aid 3 by in-mold injection molding, insertion, riveting, or other methods. The flipping connection between the elastic element 4 and the frame 2 allows the shaving aid 3 to automatically adjust to a certain angle according to the shaving angle and the user's facial contours, enhancing shaving fit and improving user comfort and shaving effect.

[0032] Optionally, combined Figures 1 to 4As shown, the frame 2 has elastic members 4 connected to its upper and lower sides, and each elastic member 4 is connected to a shaving aid 3. The frame 2 has one elastic member 4 on its upper and lower sides, preferably symmetrically arranged. One end of each elastic member 4 is fixed to the frame 2, and the other end is connected to a shaving aid 3. The two shaving aids 3 can independently flip around their respective elastic member 4 axes and return to their default positions when not in use. The shaving aids 3 can be of the same material or a dual-form structure with different shaving functions or ingredients (e.g., cleaning + lubricating). By setting shaving aids 3 on the upper and lower sides respectively, multiple shaving experiences can be provided during shaving, such as simultaneously achieving multiple effects like lubrication, soothing, and cleaning, enhancing product functionality and differentiation. The two shaving aids 3 are independently flipped and connected via their respective elastic members 4, allowing them to adaptively adjust according to the shaving angle and facial contours, helping to improve shaving smoothness and user comfort.

[0033] Optionally, combined Figure 2 , Figure 3 As shown, the first limiting group 21 includes a first limiting piece 211 and a second limiting piece 212. The frame 2 has an inner side 23. The first limiting piece 211 and the second limiting piece 212 are respectively disposed at the upper and lower ends of the inner side 23, and the first limiting piece 211 and the second limiting piece 212 are both located at the front end of the inner side 23. When the shaver head 1 is installed in the frame 2, the front side of the shaver head 1 abuts against the rear surface of the first limiting piece 211 and the rear surface of the second limiting piece 212.

[0034] The first limiting piece 211 and the second limiting piece 212 are preferably fixed to the frame 2 by integral injection molding or insertion structure. The inner surface 23 refers to the inner surface of the frame 2 used to accommodate the shaver head 1, and the front end area of ​​this surface is provided with the first limiting piece 211 and the second limiting piece 212. When the shaver head 1 is installed, its front surface simultaneously contacts the rear surface of these two limiting pieces to achieve forward limiting positioning. The two limiting pieces can be a raised rib structure, a barbed structure, or a wedge-shaped structure to enhance the limiting effect and adapt to different shapes of shaver heads 1. By providing limiting pieces at both ends and located at the front end of the inner surface 23, the front surface of the shaver head 1 can stably abut against the limiting pieces when installed, effectively preventing forward displacement or loosening during use, and ensuring stability and safety during shaving.

[0035] Optionally, combined Figure 2 , Figure 3As shown, the first limiting piece 211 extends downward from the front end of the inner side surface 23, and the second limiting piece 212 extends upward from the front end of the inner side surface 23; both the first limiting piece 211 and the second limiting piece 212 are flush with the front surface of the frame 2. The design of the first limiting piece 211 extending downward and the second limiting piece 212 extending upward allows the limiting pieces to better abut against the front side of the shaver head 1 when it is installed, providing stable support and precise positioning, ensuring that the limiting pieces form a complete limiting area at the front end of the frame 2, thereby enhancing the accuracy and stability of forward positioning; the design of the limiting pieces being flush with the front surface of the frame 2 makes the shaver head look cleaner and more aesthetically pleasing.

[0036] Optionally, combined Figures 1 to 4 As shown, when the shaver head 1 is installed inside the frame 2, the inner side surface 23 circumferentially abuts against the outer side wall of the shaver head 1, that is, the frame 2 forms a surrounding enveloping structure for the shaver head 1. The circumferential abutment means that multiple positions (e.g., front, back, left, right, or annular area) of the inner side surface 23 of the frame 2 are tightly fitted with the corresponding outer side wall of the shaver head 1, forming a stable fit relationship of surface contact or multi-point contact. The circumferential abutment between the inner side surface 23 and the outer side wall of the shaver head 1 ensures that the shaver head 1 does not wobble during shaving, which helps to maintain a uniform fit between the head and the skin, thereby improving shaving efficiency and safety. When the shaver head 1 is inserted, it is automatically guided into place by the circumferential fit structure, avoiding misalignment or jamming, simplifying user operation, and improving the user experience.

[0037] Optionally, combined Figure 1 , Figure 4 As shown, the second limiting group 22 includes a first latch 221 and a second latch 222. The first latch 221 and the second latch 222 are both located at the rear end of the frame 2, and the first latch 221 and the second latch 222 are located on the upper and lower sides of the frame 2, respectively. When the shaver head 1 is installed in the frame 2, the rear side of the shaver head 1 abuts against the front surface of the first latch 221 and the front surface of the second latch 222, respectively. When the frame 2 needs to detach from the shaver head 1, the first latch 221 is pushed to deform so that the shaver head 1 is freed from the restriction of the first latch 221, and then the shaver head 1 is moved so that the shaver head 1 is freed from the restriction of the second latch 222, thereby achieving complete separation of the frame 2 from the shaver head 1.

[0038] The first latch 221 is located at the upper rear end of the frame 2, and the second latch 222 is located at the lower rear end of the frame 2. The two latching structures together constitute a limiting and fixing mechanism for the rear side of the shaver head 1. When the shaver head 1 is inserted into the frame 2, its rear side will abut against the front surfaces of the first latch 221 and the second latch 222 respectively. Thus, under the action of the bidirectional limiting structure with the first limiting group 21 at the front and the two latches at the rear, the shaver head 1 is stably clamped in the frame 2. During use, when the user needs to disassemble the frame 2 to replace the shaving aid 3 component, they only need to manually push (e.g., with a finger) the first latch 221 located on the upper side to cause it to elastically deform, so that the rear side of the shaver head 1 is released from the clamping restriction of the first latch 221. Then, by moving the shaver head 1 upward or backward, it can be completely released from the restriction of the second latch 222 below, thus achieving smooth separation of the frame 2 and the shaver head 1. The above structure facilitates the quick installation and removal of the three shaving aid components, improving ease of use and product maintenance efficiency. The first snap-fit ​​position 221 and the second snap-fit ​​position 222 are arranged vertically and can be formed by one-piece plastic injection molding or insert molding, which is a mature manufacturing process with low cost and high reliability.

[0039] In this embodiment, the user only needs to push the first latch 221 to deform it to release the shaver head 1 smoothly, realizing a quick one-handed disassembly operation and providing a good user experience; the second latch 222 is located below, and the entire separation can only be achieved by guidance after the first latch 221 is released, which improves safety and prevents it from falling or loosening in an unexpected state.

[0040] Optionally, combined Figure 1 , Figure 4 As shown, the second limiting group 22 is also provided with a pushing plate 223 for easy application of force, and the first fastener 221 is provided on the pushing plate 223. The pushing plate 223 is an outwardly protruding structure located at the rear end of the frame 2. Its shape can be a flat plate, an arc-shaped boss, or a pry bar with a certain degree of elasticity, and its size is suitable for the user's finger pressing operation. The first fastener 221 is integrally or assembled onto the pushing plate 223. As the pushing plate 223 is pressed and deformed, the first fastener 221 undergoes elastic deformation, thereby releasing the limiting and holding relationship with the rear side of the shaver head 1. The setting of the pushing plate 223 allows the user to apply external force more conveniently and accurately for disassembly operations in actual use, avoiding the inconvenience or slippage caused by directly operating the small fastener.

[0041] Optionally, combined Figure 1 , Figure 4As shown, the second latch 222 includes two latches 2221 spaced apart on the left and right sides. The two latches 2221 are located on the lower part of the rear end of the frame 2 and are distributed on the left and right sides at a certain interval. Each latch 2221 has a hook-shaped or barbed structure. When the shaver head 1 is installed inside the frame 2, the rear side of the shaver head 1 abuts against the front surface of the two latches 2221, forming a double-point engagement with the shaver head 1. When it is necessary to remove the shaver head 1 from the frame 2, the first latch 221 is pushed to release it, allowing the shaver head 1 to be easily moved and thus disengaged from the restraint of the two latches 2221, thereby achieving complete separation of the frame 2 from the shaver head 1.

[0042] Another embodiment of the present invention provides a hair trimmer, including a shaving aid assembly that is easy to disassemble and install as described above.

[0043] The hair trimmer in this embodiment, through the detachable frame 2 and the front and rear limiting structures of the first limiting group 21 and the second limiting group 22, ensures that the shaver head 1 can be stably positioned during use, ensuring a stable and reliable shaving effect. The second limiting group 22 can deform under external force, thereby realizing the quick assembly and disassembly of the shaver head 1 and the frame 2, which is simple to operate and improves the user's convenience and experience. When replacing the shaving aid 3, only the frame 2 needs to be removed from the shaver head 1, and the shaving aid 3 is removed along with the frame 2, without the need to replace the entire shaver head 1. The operation is simple, which can effectively reduce the user's operating costs, avoid the waste of resources caused by frequent replacement of the shaver head, and improve the product's economic and environmental value.
