Description

Technical Field

[0001] This application relates to the field of razor technology, and more particularly to a manual razor. Background Technology

[0002] A manual razor consists of three main parts: a handle, a connecting mechanism, and a razor head. The razor head includes a blade holder and blades mounted on it. The connecting mechanism connects the handle and the blade holder, thus assembling the razor head and the handle.

[0003] Currently, to facilitate head replacement, most manual razors on the market use a clamp-type connection structure, meaning the connecting mechanism is attached to the razor head via a clamping method. However, this method has significant drawbacks in practical use: replacing the razor head is complicated and inefficient. Utility Model Content

[0004] This application provides a manual razor to solve the problems existing in related technologies. The technical solution is as follows:

[0005] This application provides a manual razor, including:

[0006] handle;

[0007] The cutting head has a slot or a fastener;

[0008] A connecting frame is provided, which is connected to the handle. The connecting frame is provided with an elastic buckle, which has a locked state and an unlocked state. In the locked state, the elastic buckle engages with the slot or buckle body to connect the connecting frame and the blade head together. In the unlocked state, the elastic buckle disengages from the slot or buckle body to allow the blade head to detach from the connecting frame. The elastic buckle can maintain the unlocked state under the action of elastic force.

[0009] A sliding component, slidably disposed on the connecting frame, has a first station and a second station. The first station is where the sliding component engages with the elastic buckle to restrict the elastic buckle to a locked state. The second station is where the sliding component disengages from the elastic buckle, allowing the elastic buckle to be switched to an unlocked state.

[0010] A first elastic component is disposed between the connecting frame and the sliding component, and the first elastic component is used to provide the sliding component with an elastic force to maintain the first working position.

[0011] In one embodiment, the manual razor further includes:

[0012] An operating component is rotatably mounted on the connecting frame. When the operating component rotates toward the cutter head, it abuts against the sliding component to push the sliding component to slide along the direction from the first station to the second station.

[0013] In one embodiment, the cutter head further has a connecting cavity, the rear end of the connecting cavity is open, the slot communicates with the connecting cavity, or the buckle body is disposed in the connecting cavity;

[0014] The connecting frame is provided with a first connecting part, which is adapted to the connecting cavity, and the elastic buckle is provided on the first connecting part.

[0015] In one embodiment, the connecting frame has a first clearance opening and a guide groove. The first clearance opening is located on the first connecting portion, the first clearance opening accommodates the elastic buckle and allows the elastic buckle to move, and the guide groove extends into the first connecting portion and communicates with the first clearance opening.

[0016] The sliding component is slidably engaged with the guide groove.

[0017] In one embodiment, the rear end of the first connecting part is provided with two first connecting arms, which are respectively placed on the upper and lower sides of the sliding component. The ends of the two first connecting arms opposite to the first connecting part are connected by a vertical limiting component, which is used to restrict the sliding component from disengaging from the guide groove.

[0018] In one embodiment, a first end of the first elastic member is connected to the sliding member, and a second end of the first elastic member is connected to the vertical limiting member.

[0019] In one embodiment, both first connecting arms are provided with first connecting holes, the first end of the vertical limiting component is adapted to the first connecting hole on one of the first connecting arms, and the second end of the vertical limiting component is adapted to the first connecting hole on the other first connecting arm.

[0020] In one embodiment, the slots are provided on both the upper and lower sides of the connecting cavity, and the elastic buckles are provided on both the upper and lower sides of the first connecting part, with each elastic buckle cooperating with the corresponding slot.

[0021] Alternatively, the connecting cavity may be provided with buckle bodies on both the left and right sides, and the first connecting part may be provided with elastic buckles on both the left and right sides, with each elastic buckle cooperating with the corresponding buckle body.

[0022] In one embodiment, the cutter head includes:

[0023] The support, having the slot or the buckle; and

[0024] A blade holder, which is sway-up and down at the front end of the support;

[0025] The manual razor also includes:

[0026] A push rod is slidably mounted on the sliding component. The front end of the push rod passes through the front end of the connecting frame and the front end of the support, and the push rod abuts against the blade holder.

[0027] The second elastic component has a first end connected to the connecting frame and a second end connected to the top rod. The second elastic component is used to provide the top rod with an elastic force that keeps it in contact with the blade holder.

[0028] In one embodiment, the connecting bracket is swayable left and right on the handle;

[0029] The manual razor also includes:

[0030] A third elastic component is disposed on the connecting frame and extends laterally. The two ends of the third elastic component are respectively connected to the handle, or one end of the two ends of the third elastic component is connected to the handle and the other end of the two ends of the third elastic component is connected to the connecting frame. The third elastic component is used to provide an elastic force that causes the connecting frame to return to the center position after swinging left and right.

[0031] The advantages or beneficial effects of the above technical solutions include at least the following:

[0032] This utility model discloses a manual razor that integrates a handle, razor head, connecting frame, sliding component, and first elastic component, enabling quick assembly and disassembly of the razor head and improving operational efficiency. Specifically, when disassembling the razor head, the sliding component is operated to switch from the first position to the second position, disengaging the sliding component from the elastic latch. The elastic latch then returns to its unlocked state under its own elastic force, disengaging from the latch or locking body, allowing the razor head to be removed. Similarly, when assembling the razor head, the sliding component is operated to switch from the first position to the second position. The workstation disengages the sliding component from the elastic latch, allowing the elastic latch to reset to the unlocked state under its own elastic force. This ensures that the elastic latch does not interfere with the insertion of the cutter head. After the cutter head is mounted on the connecting frame, the sliding component is released. Under the elastic force of the first elastic component, the sliding component automatically pushes the elastic latch to engage with the slot or latch of the cutter head, thus connecting the cutter head to the connecting frame. Whether installing or removing the cutter head, simply driving the sliding component to slide is sufficient to complete the installation or removal. The operation is simple, convenient, and efficient, enhancing the user experience.

[0053] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0054] See Figures 1-16 This invention illustrates a preferred embodiment of a manual razor, comprising:

[0055] Handle 1;

[0056] Cutter head 2, cutter head 2 has a slot 211 or a buckle 212;

[0057] The connecting frame 3 is connected to the handle 1. The connecting frame 3 is provided with an elastic buckle 31. The elastic buckle 31 has a locked state and an unlocked state. In the locked state, the elastic buckle 31 cooperates with the slot 211 or the buckle body 212 to connect the connecting frame 3 and the cutter head 2 together. In the unlocked state, the elastic buckle 31 disengages from the slot 211 or the buckle body 212 so that the cutter head 2 can be disengaged from the connecting frame 3. The elastic buckle 31 can maintain the unlocked state under the action of elastic force.

[0058] A sliding component 4 is slidably mounted on the connecting frame 3. The sliding component 4 has a first station and a second station. The first station is where the sliding component 4 engages with the elastic buckle 31 to lock the elastic buckle 31. The second station is where the sliding component 4 disengages from the elastic buckle 31, allowing the elastic buckle 31 to be switched to an unlocked state.

[0059] The first elastic component 5 is disposed between the connecting frame 3 and the sliding component 4. The first elastic component 5 is used to provide the sliding component 4 with an elastic force to maintain it in the first working position.

[0060] This utility model of a manual razor integrates a handle 1, a razor head 2, a connecting frame 3, a sliding component 4, and a first elastic component 5, enabling quick assembly and disassembly of the razor head 2 and improving operational efficiency. Specifically, when disassembling the razor head 2, the sliding component 4 is operated to slide from the first position to the second position, disengaging the sliding component 4 from the elastic latch 31. The elastic latch 31 then returns to its unlocked state under its own elastic force, disengaging from the latch 211 or the retaining body 212, allowing the razor head 2 to be removed. Similarly, when assembling the razor head 2, the sliding component 4 is operated to slide from the first position to the second position. In the second station, the sliding component 4 disengages from the elastic buckle 31, allowing the elastic buckle 31 to reset to the unlocked state under its own elastic force. This ensures that the elastic buckle 31 does not interfere with the insertion of the cutter head 2. After the cutter head 2 is installed on the connecting frame 3, the sliding component 4 is released. Under the elastic force of the first elastic component 5, the sliding component 4 automatically pushes the elastic buckle 31 to engage with the slot 211 or buckle of the cutter head 2, thereby connecting the cutter head 2 to the connecting frame 3. Whether installing or removing the cutter head 2, only the sliding component 4 needs to be driven to slide to complete the installation or removal of the cutter head 2. The operation is simple, convenient, and efficient, which can improve the user experience.

[0061] To facilitate the sliding of component 4, see [reference needed]. Figure 1 In one embodiment, the manual razor further includes:

[0062] The operating component 6 is rotatably mounted on the connecting frame 3. When the operating component 6 rotates towards the cutter head 2, it abuts against the sliding component 4, pushing the sliding component 4 to slide in the direction of switching from the first station to the second station. By adding the operating component 6 rotatably mounted on the connecting frame 3, the user can easily drive the operating component 6 to abut against the sliding component 4 by simply rotating it, thereby directly converting the rotational motion into the linear displacement of the sliding component 4, pushing the sliding component 4 to switch from the first station to the second station. The design of the operating component 6 utilizes the lever principle to achieve labor-saving operation, allowing the user to slide the sliding component 4 with one hand, making the operation more labor-saving, convenient, and efficient.

[0063] See Figure 6 and Figure 8 In one embodiment, the cutter head 2 also has a connecting cavity 213, the rear end of the connecting cavity 213 is open, the slot 211 communicates with the connecting cavity 213, or the buckle body 212 is disposed in the connecting cavity 213;

[0064] The connecting frame 3 is provided with a first connecting part 32, which is adapted to the connecting cavity 213, and an elastic buckle 31 is provided on the first connecting part 32. By providing a connecting cavity 213 with an open rear end on the cutter head 2, and making the slot 211 communicate with the connecting cavity 213 or directly placing the buckle body 212 in the connecting cavity 213, while adapting the shape of the first connecting part 32 of the connecting frame 3 to the connecting cavity 213 and integrating the elastic buckle 31 on the first connecting part 32, this structure uses the open connecting cavity 213 and the adapted first connecting part 32 to form a guiding and accommodating space, ensuring that the cutter head 2 and the connecting frame 3 are quickly and accurately aligned and inserted. Combined with the cooperation of the elastic buckle 31 with the slot 211 or the buckle body 212, the connection stability between the cutter head 2 and the connecting frame 3 can be improved.

[0065] See Figure 8 In one embodiment, the connecting frame 3 has a first clearance opening 33 and a guide groove 34. The first clearance opening 33 is located on the first connecting portion 32. The first clearance opening 33 accommodates the elastic buckle 31 and allows the elastic buckle 31 to move. The guide groove 34 extends into the first connecting portion 32 and communicates with the first clearance opening 33.

[0066] The sliding component 4 and the guide groove 34 are slidably engaged. Thus, the guide groove 34 can be used to precisely and linearly guide and constrain the running path of the sliding component 4, ensuring that the movement trajectory of the sliding component 4 is accurate and reliable when sliding smoothly within the guide groove 34, effectively preventing deviation or jamming. When the sliding component 4 is controlled to slide, at least a portion of it can extend into or out of the space aligned with the first clearance opening 33, thereby directly and reliably pushing or releasing the elastic latch 31 to deform, achieving precise control over the locking state of the elastic latch 31. This integrated guiding and clearance structure improves the smoothness and reliability of the unlocking and locking actions of the elastic latch 31 during the replacement of the cutter head 2.

[0067] See Figure 5 and Figure 8In one embodiment, the rear end of the first connecting part 32 is provided with two first connecting arms 35, which are respectively placed on the upper and lower sides of the sliding member 4. The ends of the two first connecting arms 35 away from the first connecting part 32 are connected by a vertical limiting member 36, which is used to restrict the sliding member 4 from disengaging from the guide groove 34. By setting two first connecting arms 35 on the upper and lower sides of the sliding component 4 at the rear end of the first connecting part 32, and connecting the far ends of the two first connecting arms 35 together with the vertical limiting component 36, this structure together forms a closed frame structure surrounding the sliding component 4. The upper and lower distributed first connecting arms 35 provide symmetrical support and constraint, effectively enhancing the structural strength of the rear end of the first connecting part 32. At the same time, the setting of the vertical component can prevent the sliding component 4 from accidentally disengaging from the guide groove 34 during the sliding process, ensuring that the sliding component 4 always slides stably along the predetermined guide groove 34 trajectory, thereby improving the reliability and stability of the tool head 2 replacement or unlocking operation. In addition, when installing the sliding component 4, the sliding component 4 is inserted into the guide groove 34 through the gap between the two first connecting arms 35, and then the vertical limiting component 36 is installed on the two first connecting arms 35, making the installation of the sliding component 4 more convenient and efficient.

[0068] See Figure 5 In one embodiment, the first end of the first elastic component 5 is connected to the sliding component 4, and the second end of the first elastic component 5 is connected to the vertical limiting component 36. By connecting the first end of the first elastic component 5 to the sliding component 4 and its second end to the vertical limiting component 36, this structure utilizes the vertical limiting component 36 as a stable and reliable force-bearing fulcrum, enabling the first elastic component 5 to generate an elastic restoring force acting on the sliding component 4. When the sliding component 4 is driven by an external force to slide and compress or stretch the first elastic component 5 to store energy, once the external force is released, the elastic potential energy stored in the first elastic component 5 will be released, driving the sliding component 4 to automatically and accurately reset to the first working position. This design places the first elastic component 5 between the vertical limiting component 36 and the sliding component 4, eliminating the need for additional fixing structures, simplifying the overall structure, saving internal space, and ensuring the smoothness, consistency, and high reliability of the sliding component 4's reset action, thereby improving the convenience of operation and the service life of the entire mechanism.

[0069] To facilitate the installation of the first elastic component 5, in one embodiment, the first end of the first elastic component 5 is sleeved on the outside of the first connecting post on the sliding component 4, and the second end of the first elastic component 5 abuts against the vertical limiting component 36.

[0070] In one embodiment, the first elastic component 5 is a spring. Of course, in other embodiments, the first elastic component 5 can also be a commonly used elastic component such as a spring sheet or an elastic bellows.

[0071] For easy fixing of the vertical limiting component 36, see [reference needed]. Figure 8 In one embodiment, both first connecting arms 35 are provided with first connecting holes 351, the first end of the vertical limiting member 36 is adapted to the first connecting hole 351 on one of the first connecting arms 35, and the second end of the vertical limiting member 36 is adapted to the first connecting hole 351 on the other first connecting arm 35.

[0072] See Figures 1-6 In one embodiment, the connecting cavity 213 is provided with slots 211 on both the upper and lower sides, and the first connecting part 32 is provided with elastic buckles 31 on both the upper and lower sides. Each elastic buckle 31 cooperates with the corresponding slot 211 to increase the connection stability between the cutter head 2 and the connecting frame 3.

[0073] See Figures 1-6 In one embodiment, the connecting cavity 213 is provided with two slots 211 on both the upper and lower sides, and the first connecting part 32 is provided with two elastic buckles 31 on both the upper and lower sides. Each elastic buckle 31 cooperates with the corresponding slot 211 to further increase the connection stability between the cutter head 2 and the connecting frame 3.

[0074] See Figures 9-12 Both sides of the connecting cavity 213 are provided with buckle bodies 212, and both sides of the first connecting part 32 are provided with elastic buckles 31. Each elastic buckle 31 cooperates with the corresponding buckle body 212 to increase the connection stability between the cutter head 2 and the connecting frame 3.

[0075] See Figures 1-2 In one embodiment, the cutter head 2 includes:

[0076] Support 21, support 21 having a slot 211 or a buckle 212; and

[0077] The blade holder 22 is mounted on the front end of the support 21 and can swing up and down so that the blades on the blade holder 22 can adapt to the contours of the human face.

[0078] Manual razors also include:

[0079] The push rod 7 is slidably mounted on the sliding component 4. The front end of the push rod 7 passes through the front end of the connecting frame 3 and the front end of the support 21, and the push rod 7 abuts against the blade holder 22.

[0080] The second elastic component 8 has its first end connected to the connecting frame 3 and its second end connected to the push rod 7. The second elastic component 8 provides an elastic force to the push rod 7, ensuring it remains in contact with the blade holder 22. Thus, by continuously applying an elastic force towards the blade holder 22 using the second elastic component 8, the tip of the push rod 7 remains in contact with the blade holder 22. When facial contours change during shaving, causing the blade holder 22 to swing up and down, the push rod 7, supported by the second elastic component 8, slides and extends accordingly, dynamically transmitting the elastic force to the blade holder 22. This allows the blade holder 22 to smoothly and adaptively conform to the facial curves, ensuring continuous stability and comfort during shaving and improving shaving performance.

[0081] To ensure reliable installation of the second elastic component 8, in one embodiment, the first end of the second elastic component 8 abuts against the rotating shaft 10 on the connecting frame 3, and the second end of the second elastic component 8 is sleeved on the second connecting post of the top rod 7.

[0082] In one embodiment, the second elastic component 8 can be a spring. Of course, in other embodiments, the second elastic component 8 can be a commonly used elastic component such as a spring sheet or an elastic bellows.

[0083] See Figure 3 and Figure 14 In one embodiment, the connecting frame 3 is mounted on the handle 1 and can swing left and right so that the blade head 2 can swing left and right, thereby allowing the blade head 2 to better adapt to the contours of the human face.

[0084] Manual razors also include:

[0085] The third elastic component 9 is disposed on the connecting frame 3 and extends laterally. The two ends of the third elastic component 9 are respectively connected to the handle 1, or one end of the two ends of the third elastic component 9 is connected to the handle 1 and the other end of the two ends of the third elastic component 9 is connected to the connecting frame 3. The third elastic component 9 is used to provide an elastic force that causes the connecting frame 3 to return to the center position after swinging left and right. By mounting the connecting frame 3 on the handle 1 in a way that allows it to swing left and right, and by providing a third elastic component 9 extending laterally on the connecting frame 3 (with its two ends connected to the handle 1 or one end connected to the handle 1 and the other end connected to the connecting frame 3), this structure utilizes the lateral elastic deformation characteristics of the third elastic component 9 to provide restoring force. When the shaving head 2 is subjected to the lateral force of the facial contour during shaving, causing the connecting frame 3 to swing left and right relative to the handle 1, the third elastic component 9 is stretched or compressed accordingly and stores elastic potential energy. Once the lateral force is eliminated, this elastic potential energy drives the connecting frame 3 to automatically and accurately return to a stable central position, ensuring that the shaving head 2 swings left and right flexibly and smoothly and returns to its central position in a timely and reliable manner. This allows it to better adapt to the undulations of the human face contour, comprehensively improving the closeness, comfort, and operational stability of shaving.

[0086] See Figure 3 and Figure 14 In one embodiment, the connecting frame 3 is provided with a rotating shaft 10 in the middle. The rotating shaft 10 extends vertically. The upper end of the rotating shaft 10 is rotatably disposed on the second connecting arm 11 of the handle 1, and the lower end of the rotating shaft 10 is rotatably disposed on the third connecting arm 12 of the handle 1, so that the connecting frame 3 can swing left and right stably, that is, the cutter head 2 can swing left and right stably.

[0087] See Figure 3 and Figure 8 In one embodiment, the connecting frame 3 is provided with a second connecting part 37, which is sleeved on the outside of the rotating shaft 10;

[0088] The second connecting arm 11 has a third connecting part 111 at each of its two transverse ends. The two third connecting parts 111 are respectively placed on the transverse sides of the second connecting part 37. The third connecting part 111 has a first limiting groove 1111.

[0089] The third elastic component 9 is a spring sheet. The spring sheet passes through the rotating shaft 10 and the second connecting part 37. The first lateral end of the spring sheet is connected to the first limiting groove 1111 on one of the third connecting parts 111, and the second lateral end of the spring sheet is connected to the first limiting groove 1111 on the other third connecting part 111. In this way, the connecting frame 3 is sleeved on the rotating shaft 10 through its second connecting part 37, so that it can swing left and right on the handle 1. The third connecting parts 111 at both ends of the second connecting arm 11 have first limiting grooves 1111. The third elastic component 9 is in the form of a spring sheet. The spring sheet passes through the rotating shaft 10 and the second connecting part 37. Its first lateral end and second lateral end are respectively connected to the first limiting grooves 1111 on the two third connecting parts 111, thereby fixing the spring sheet on the handle 1. This structure utilizes the elastic characteristics of the spring sheet's lateral extension. When the cutter head 2 is driven by the lateral force of the facial contour, the connecting frame 3 can be fixed. When the spring oscillates around the pivot 10, it undergoes elastic deformation and stores potential energy. Once the lateral force is eliminated, the spring releases its potential energy to drive the connecting frame 3 to automatically return to the center position. This solution integrates the swing support and elastic return function into a single spring component through the integrated design of the spring, pivot 10, second connecting part 37 and first limiting groove 1111. This eliminates the need for additional connecting structures, greatly simplifies the overall structure, reduces the number of parts and assembly costs, and ensures that the blade head 2 swings flexibly and returns to its position accurately and reliably, so that it can better adapt to changes in facial contours and improve shaving closeness and comfort.

[0090] See Figure 7 In one embodiment, the third connecting part 111 has a second connecting hole 1112, which is perpendicular to the first limiting groove 1111. The second connecting hole 1112 communicates with the corresponding first limiting groove 1111. The second connecting hole 1112 is used to connect with a fastening member (not shown in the figure). A portion of the fastening member extends into the first limiting groove 1111 and abuts the spring against the side wall of the first limiting groove 1111 to restrict the spring from disengaging from the first limiting groove 1111, thereby reliably fixing the spring to the third connecting part 111.

[0091] Specifically, the fastening component mentioned above can be a bolt.

[0092] See Figure 14 , Figure 15 and Figure 16 In one embodiment, the second connecting arm 11 is provided with a third connecting part 111, the third connecting part 111 having a first limiting groove 1111, and the connecting frame 3 is provided with a fourth connecting part 38, the fourth connecting part 38 and the third connecting part 111 being disposed on the lateral sides of the second connecting part 37, and the fourth connecting part 38 having a second limiting groove 381.

[0093] The third elastic component 9 is a torsion spring. The main body of the torsion spring is sleeved outside the second connecting part 37. The first extension arm of the torsion spring is inserted into the first limiting groove 1111, and the second extension arm of the torsion spring is inserted into the second limiting groove 381. By providing a third connecting part 111 with the first limiting groove 1111 on the second connecting arm 11 of the handle 1, and providing a fourth connecting part 38 with the second limiting groove 381 on the connecting frame 3, and placing the third connecting part 111 and the fourth connecting part 38 on the lateral sides of the second connecting part 37 respectively, and specifically using a torsion spring as the third elastic component 9, with the main body of the torsion spring sleeved outside the second connecting part 37, and its first and second extension arms inserted into the first limiting groove 1111 of the third connecting part 111 and the second limiting groove 381 of the fourth connecting part 38 respectively; this structure utilizes the torsional elasticity characteristics of the torsion spring. When the cutter head 2 is driven by a lateral force to swing the connecting frame 3 left and right relative to the handle 1, it will drive the fourth connecting part 38 to move synchronously, thereby forcing the extension of the torsion spring. The arm (first extension arm or second extension arm) undergoes torsional deformation and stores recovery potential energy within the limiting groove (first limiting groove 1111 or second limiting groove 381). After the lateral force disappears, the torsion spring releases its potential energy to drive the connecting frame 3 to automatically and accurately return to the centered position. This solution integrates the swing support and elastic return function into a single torsion spring component through the tight cooperation between the torsion spring, the second connecting part 37, and the two limiting grooves (first limiting groove 1111 and second limiting groove 381). This eliminates the need for additional connecting structures, significantly simplifies the overall structure, and reduces manufacturing and assembly costs. At the same time, it ensures that the shaving head 2 swings flexibly and smoothly and has a timely and reliable return response, enabling it to efficiently adapt to the undulations of the human face and effectively improve the closeness, comfort, and operational stability of shaving.
