Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, specifically to a hair clipper with an adjustable blade angle. Background Technology

[0002] A hair clipper is a tool for trimming hair, also called a hair trimmer. In existing hair clippers, the outer shell and the blade are usually connected as one piece. During the haircutting process, you need to bend your hand for a long time to trim the hair while holding the hair clipper. At the same time, some parts are difficult to operate when cutting hair at home, making it inconvenient to use.

[0003] Authorized announcement number CN217597161U discloses a rotatable and bendable hair clipper, which includes a handle, a clipper holder installed at one end of the handle, and a clipper head installed at one end of the clipper holder. A rotating mechanism is provided at the connection between the handle and the clipper holder. The rotating mechanism includes a rotating groove formed at one end of the clipper holder, a rotating seat integrally formed at one end of the handle, a damping rotating shaft installed inside the rotating groove, and a damping rotating sleeve fixed inside the rotating seat. The rotating seat is rotatably mounted on the damping rotating shaft through the damping rotating sleeve. A fixing mechanism is provided at one end of the damping rotating shaft. This discloses a hair clipper that can adjust the angle between the clipper head and the handle using the damping rotating sleeve. Although it can make hair cutting more convenient, during use, it is easy to accidentally push the clipper head to rotate, resulting in instability. Utility Model Content

[0004] The technical problem this invention aims to solve is that after adjusting the angle between the blade and the handle, the angle between the blade and the handle cannot be stably fixed.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a hair clipper with an adjustable blade angle is provided, including a housing, a ball rotatably mounted on the housing, a blade mounted on the ball, a damping assembly inside the housing, and a damping part on the side of the ball corresponding to the position of the damping assembly, for limiting the rotation of the ball.

[0007] Furthermore, the damping assembly includes a damping element that cooperates with the damping section.

[0008] Furthermore, a mounting base is provided inside the housing, and the damping element is movably mounted on the mounting base via a first elastic element.

[0009] Furthermore, the damping part includes several evenly distributed limiting grooves, the cross-section of which is an isosceles trapezoid with an open bottom, and the end of the damping member is provided with two inclined surfaces that cooperate with the limiting grooves.

[0010] Furthermore, the damping part includes a first rough surface disposed on the surface of the sphere, and the end of the damping member is provided with a matching second rough surface.

[0011] Furthermore, a rotating handle is installed on the sphere.

[0012] Furthermore, the housing is provided with a drive assembly for moving the damping element.

[0013] Furthermore, the drive assembly includes a baffle and a rocker plate. The rocker plate is provided with a rotating shaft that is rotatably connected to the housing. A pin is installed at one end of the rocker plate, and the end of the baffle is rotatably connected to the pin. An unlocking hole is provided on the baffle plate.

[0014] This invention has the following advantages: By setting a damping part on the sphere and a damping element inside the shell, the cooperation between the damping part and the damping element is used to lock the rotation of the sphere, thereby conveniently fixing the cutter head at a specified angle, which is convenient for users. At the same time, by selecting different damping parts and matching damping elements, more gears and arbitrary angle locking can be achieved within a certain angle, making the application range wider. In addition, the angle of the cutter head can only be adjusted by pressing the button, preventing the angle change of the cutter head due to external force during use, making it more stable and effective.

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that all directional indicators in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides a hair clipper with an easily adjustable blade angle, such as... Figure 1 and Figure 2As shown, the device includes a long, narrow outer shell 10, with an opening at one end. A sphere 20 is rotatably mounted at the opening, and the side of the sphere 20 fits against the edge of the opening of the outer shell 10 to prevent hair clippings from entering the outer shell 10. A hair clipper head 11 is mounted on the sphere 20. The user holds the outer shell 10 and then rotates the sphere 20, thereby changing the angle of the hair clipper head 11 relative to the outer shell 10 to adapt to different hair cutting situations. The sphere 20 can also be replaced with a cylinder, with its side rotatably connected to the opening of the outer shell 10. The hair clipper head 11 is mounted on the side of the cylinder. The shape of the component rotatably connected to the outer shell 10 can be selected according to the actual situation.

[0032] Specifically, in this embodiment, the rotation center of the sphere 20 relative to the outer shell 10 passes through the center of the sphere 20, ensuring that the sphere 20 can stably fit against the outer shell 10 during rotation. A rotating handle 21 is installed on the side of the sphere 20, and the rotation axis of the rotating handle 21 passes through the center of the sphere 20. By rotating the rotating handle 21, the sphere 20 can be rotated relative to the outer shell 10, which is convenient to operate.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in order to ensure that the sphere 20 can maintain its state stably after rotating a certain angle, a damping component 30 is provided inside the outer shell 10, and a damping part is provided on the side of the sphere 20 corresponding to the position of the damping component 30 to limit the rotation of the sphere 20.

[0034] like Figures 3-6 As shown, in this embodiment, a mounting base 35 is fixedly disposed inside the outer shell 10, and a damping member 31 passes through the mounting base 35. The flat end of the damping member 31 extends out of the mounting base 35, and the cylindrical end is flush with the surface of the mounting base 35. A first elastic member 33 is disposed inside the mounting base 35. The first elastic member 33 causes the damping member 31 and the mounting base 35 to have a tendency to move relative to each other. The first elastic member 33 is a spring.

[0035] like Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, a baffle 41 is provided inside the outer casing 10. The side of the baffle 41 contacts one cylindrical end of the locking member 31 to prevent the locking member 31 from moving away from the locking groove. The baffle 41 is provided with an unlocking hole 42. Specifically, the unlocking hole 42 extends through one end of the baffle 41. When the baffle 41 moves upward, the unlocking hole 42 aligns with the end of the locking member 31, and the end of the locking member 31 can enter the unlocking hole 42, allowing the locking member 31 to move away from the locking groove. The locking member 31 separates from the locking groove, and then the rotation angle of the ball 20 can be adjusted.

[0036] In order to facilitate the up-and-down movement of the baffle 41, such as Figure 3 and Figure 4 As shown, a rocker plate 40 is provided inside the outer casing 10. A rotating shaft 43 passes through the middle of the rocker plate 40, and the rocker plate 40 can rotate around the axis of the rotating shaft 43. A pin 44 is provided at one end of the rocker plate 40, and a push block 45 is vertically provided at the other end. One end of the baffle 41 is rotatably connected to the pin 44. In this embodiment, by pressing down the push block 45, the pin 44 will be lifted up under the action of the rocker plate 40, thereby driving the baffle 41 to move upward. The two ends of the rotating shaft 43 are connected to the inner wall of the outer casing 10 through the bearing seat 47. A protruding stop is provided inside the outer casing 10 to prevent the baffle 41 from moving horizontally and to ensure that the baffle 41 remains vertical under the action of the rocker plate 40. At the same time, it is also to make the baffle 41 more stable against the locking member 31.

[0037] Specifically, a second elastic element 46 is provided between the side of the rocker 40 located between the pin 44 and the rotating shaft 43 and the inner wall of the outer casing 10. The second elastic element 46 has a tendency to push one end of the rocker 40 downward. In this embodiment, during use, firstly, under the action of the second elastic element 46, the end of the pin 44 on the rocker 40 will move downward, so that the side of the baffle 41 is aligned with the end of the locking member 31, achieving a locking effect. When the push block 45 is pressed down, the second elastic element 46 will be compressed, and at the same time, the baffle 41... Move upwards to align the unlocking hole 42 with the locking member 31, thereby unlocking the device and moving the locking member 31 away from the locking groove. This allows the ball 20 to be rotated to adjust the angle of the cutter head 11. When the push block 45 is released, the baffle 41 will move downwards under the action of the second elastic member 46, locking the locking member 31 again. The second elastic member 46 is a spring. To make the spring more stably mounted on the rocker plate 40, a protrusion 48 is provided on the rocker plate 40 at the position corresponding to the spring to limit the position of the spring.

[0038] like Figure 1 and Figure 4 As shown, a button 12 is provided at the position of the outer shell 10 corresponding to the push block 45. The inner side of the button 12 contacts the push block 45. When the button 12 is pressed down, the locking member 31 can be unlocked. When the button 12 is released, the second elastic 46 can reset the push block 45, thereby restoring the button 12 to its original state. In this embodiment, the angle of the blade head 11 can only be adjusted by pressing the button 12 down during use, which avoids the situation where the angle of the blade head 11 changes due to external force during hair cutting, making it more stable and reliable to use.

[0039] The outer casing 10 contains a drive assembly that can drive the damping element 31 to move. Specifically, when the damping element 31 moves toward the damping part, it can increase the pressure exerted by the damping element 31 on the damping part, thereby increasing the friction between the two. This makes it more difficult for the ball to rotate and makes it less likely to rotate. Conversely, it makes it easier for the ball to rotate. At the same time, when the damping element 31 moves to a certain extent, it can lock the ball 20 so that it cannot rotate on its own.

[0040] First embodiment:

[0041] In this embodiment, such as Figure 2 and Figure 6 As shown, the damping part consists of several limiting grooves 23 evenly distributed in the arc-shaped groove 22. The cross-section of the limiting groove 23 is an isosceles trapezoid, and the bottom of the isosceles trapezoid is open. The end of the damping member 31 is adapted to the shape of the limiting groove 23. The contact position between the end of the damping member 31 and the limiting groove 23 is two inclined surfaces 34, and the first elastic member 33 has a tendency to push the damping member 31 toward the limiting groove 23.

[0042] In this embodiment, when the end of the damping member 31 is fitted into the limiting groove 23, the baffle 41 locks the damping member 31, and the end of the damping member 31 cannot be moved out of the limiting groove 23. At this time, the effect of locking the angle of the cutter head 11 is achieved.

[0043] When the angle needs to be adjusted, press button 12. The unlocking hole 42 is aligned with the damping element 31. When the ball 20 is rotated using the rotating handle 21, the end of the damping element 31 will slowly move out of the limiting groove 23 under the action of the inclined surface 34 at the end of the damping element 31. At this time, the first elastic element 33 is compressed, and the other end of the damping element 31 enters the unlocking hole 42. When the end of the damping element 31 moves to the position of the other limiting groove 23, the end of the damping element 33 re-enters the limiting groove 23 under the action of the first elastic element 33, and the other end also moves out of the unlocking hole 42. At this time, the angle adjustment is completed, and the changed angle is the angle between the two limiting grooves 33.

[0044] Since multiple limiting grooves 33 are provided in this embodiment, multiple angle settings can be adjusted. After the angle is adjusted, the button 12 can be released. Under the action of the second elastic element 46, the baffle 41 re-seals the damping element 31, thus fixing the angle. Different settings can be selected according to actual needs. In order to facilitate user use, the ball 20 is provided with a scale so that users can quickly find the required angle.

[0045] Second embodiment:

[0046] In this embodiment, such as Figure 8 and Figure 9 As shown, the damping part consists of several spherical blind holes 24 evenly distributed in the arc-shaped groove 22. The end of the damping member 31 is equipped with several spherical protrusions 25 that cooperate with the spherical blind holes 24. Since the end of the damping member 31 that cooperates with the locking groove is flat, the several spherical protrusions 25 at the end of the damping member 31 can be arranged in a row, and the corresponding spherical blind holes 24 are also evenly distributed in rows. The corresponding first elastic member 33 also has a tendency to push the damping member 31 into the locking groove.

[0047] In this embodiment, during use, the spherical protrusion 25 first enters the corresponding row of spherical blind holes 24. At this time, the baffle 41 locks the damping element 31, and the spherical protrusion 25 cannot move out of the spherical blind hole 24, thus achieving the effect of locking the ball 20. Then, the button 12 is pressed, and the ball 20 is rotated. Under the action of the side of the spherical protrusion 25, the spherical protrusion 25 will slowly move out of the spherical blind hole 24 and enter another row of spherical blind holes 24, thereby realizing the adjustment of the angle. Compared with the first embodiment, the spherical blind hole 34 and the spherical protrusion 25 can be made smaller in this embodiment, so more gear selections can be provided when rotating the same angle, and the application range is wider.

[0048] Third Embodiment

[0049] In this embodiment, as Figure 10 and Figure 11 As shown, the damping part is a first rough surface 26 provided in the arc-shaped groove 22, and the end face of the corresponding damping member 31 is an inwardly concave arc-shaped surface 27. The arc-shaped surface 27 is provided with a second rough surface 28 that cooperates with the first rough surface 26. The large friction between the first rough surface 26 and the second rough surface 28 is used to prevent the ball 20 from rotating. At the same time, the first elastic member 33 has a tendency to move the damping member 31 away from the locking groove. Meanwhile, a ball bearing 29 is installed on the end of the damping member 31 near the baffle 41.

[0050] In this embodiment, during use, the side of the baffle 41 first contacts the ball 29, and the baffle 41 provides a clamping force to press the second rough surface 28 of the end of the damping member 31 against the first rough surface 26. At this time, due to the large friction between the second rough surface 28 and the first rough surface 26, the ball 20 cannot rotate on its own. When the button 12 is pressed, the ball 29 rolls on the side of the baffle 31, and the unlocking hole 42 slowly aligns with the ball 29. Then, under the action of the first elastic member 33, the damping member 31 slowly moves away from the ball 29. When the ball 20 is separated from the first rough surface 26, the second rough surface 28 can rotate freely. After adjusting the angle, release the button 12. Under the action of the second elastic element 46, the baffle 41 moves downward. First, the side of the unlocking hole 42 will contact the side of the ball 29 and slowly move to the outermost side of the ball 29. At the same time, the baffle 41 will slowly push the damping element 31 to move closer to the ball 20, so that the second rough surface 28 and the first rough surface 26 are re-fitted, thereby limiting the ball 20.

[0051] Since the ball 20 is limited by the second rough surface 28 and the first rough surface 26, it can be locked at any angle, achieving stepless adjustment and wider adaptability. Items with a high coefficient of friction can also be installed on the arc-shaped groove 22 and the end of the damping component 31, as long as there is sufficient friction for relative movement after they are pressed together. In addition, to provide a better feel when rotating the ball 20 in this embodiment, a damper is installed at the rotation point between the ball 20 and the outer shell 10.

[0052] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above.
