Description

Technical Field

[0001] This utility model relates to the field of shaving device technology, and in particular to a razor head and shaving device. Background Technology

[0002] Currently, to make manual razors more user-friendly, the detachable connection between the razor head and blades has been a key focus of technological improvement in this field. Currently, manual razors typically use a rotary or push-button connection between the razor head and blades. When assembling or disassembling the rotary connection structure, the user first separates the shaving head base from the old blade, then rotates the shaving head base to align the new blade with the mounting slot, and then inserts the new blade into the mounting slot for installation. When assembling or disassembling the push-button connection structure, the user first presses the release buttons on both sides simultaneously to separate the shaving head from the old blade, then applies vertical pressure to the mounting slot of the shaving head to make them engage. In summary, when connecting the shaving head and blades of the aforementioned connection structures, the user needs to carefully align the mounting slots on the shaving head and the blades before installation. If the two are significantly misaligned, they cannot be properly connected, and multiple adjustments are usually required for successful installation. Therefore, replacing the blades may take a considerable amount of time, making the operation cumbersome and inconvenient. This may lead users to prefer using the old, less effective blades already installed on the shaving head when they urgently need to shave, and then replacing the blades later, resulting in poor shaving results and skin sensitivity.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, 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, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] like Figs. 1 to 6 As shown, the side facing the user is considered the front, and the opposite side is considered the rear. The top and bottom are distinguished by the upper and lower sides of the shaver head 1 during normal operation. The left and right are distinguished by the left and right sides of the shaver head 1 when it faces the user. A razor head 1 according to this embodiment includes a razor holder 11 and a razor case 12. The razor holder 11 has a connecting mounting hole 111 and an extension hole 112 on its side relative to the left and right direction. The extension hole 112 is located in front of the mounting hole 111 and extends forward to the front side of the razor holder 11. The razor case 12 is mounted in the mounting hole 111 and can move in the left and right direction. The razor case 12 is detachably connected to the razor holder 11. The razor case 12 extends out of the razor holder 11 through the extension hole 112. The opening of the mounting hole 111 is provided with a first guide portion 114 and / or the razor case 12 is provided with a second guide portion 121 on its side relative to the left and right direction. The first guide portion 114 and the second guide portion 121 are used to guide the razor case 12 into the mounting hole 111.

[0027] In the above technical solution, the tool holder 11 is provided with a connecting mounting hole 111 and an extension hole 112. Both holes are located on the same side of the tool holder 11 in the left-right direction. The extension hole 112 is located in front of the mounting hole 111 and extends through to the front side of the tool holder 11, so that the tool box 12 can be installed into the mounting hole 111 along the side of the tool holder 11 where the mounting hole 111 and the extension hole 112 are provided, and extends forward through the extension hole 112 to the outside of the tool holder 11. Furthermore, the tool box 12 is detachably connected to the tool holder 11, so that the tool box 12 is fixed in the mounting hole 111 after being installed in the mounting hole 111. When the tool box 12 needs to be replaced, the old tool box 12 can be removed. Furthermore, the mounting hole 111... One or both of the opening of the shaver head 111 and one side of the shaver box 12 are provided with guide portions. When the shaver box 12 is inserted into the mounting hole 111, the guide portion abuts against the opening of the mounting hole 111, the guide portion abuts against the edge of the end of one side of the shaver box 12, or the two guide portions abut against each other. By moving along the guide portion, the shaver box 12 is guided into the mounting hole 111, thereby reducing the precision required for inserting the shaver box 12 into the mounting hole 111. In summary, when using the shaver head 1 and shaving device of this utility model, the user does not need to carefully align the shaver box 12 with the mounting hole 111, which can minimize the number of times the user needs to install it repeatedly, thereby making the user's operation of changing the blade simpler, more convenient and faster.

[0028] The shaving box 12 is equipped with a blade that protrudes from the front side of the shaving box 12 to enable it to shave. Other auxiliary components such as a lubricating strip can also be installed on the shaving box 12.

[0029] Alternatively, a detachable connection can be achieved by installing magnetic blocks on the tool holder 12 and the tool post 11. Another option is to install a cover plate at the mounting hole 111 after the tool holder 12 is inserted into it, thus restricting movement and achieving a detachable connection. A third option is to use bolts to pass through the tool post 11 and abut against the tool holder 12, causing the tool holder 12 to abut against the wall of the mounting hole 111, thus achieving a detachable connection. Alternatively, a snap-fit ​​part can be provided on the tool holder 12, and a connecting hole 113 can be provided on the wall of the mounting hole 111, allowing the snap-fit ​​part to engage with the connecting hole 113, thus achieving a detachable connection. These are just some examples of possible structures; no specific limitations are imposed on the detachable connection structure.

[0030] In addition, the first guide portion 114 and the second guide portion 121 can be composed of an arc surface, an inclined surface, or a combination of an arc surface and an inclined surface.

[0031] Furthermore, the first guide portion 114 includes an outer guide portion 1141 and an inner guide portion 1142. The outer guide portion 1141 is disposed along the edge of the mounting hole 111, and the inner guide portion 1142 is disposed between the inner wall of the mounting hole 111 and the outer guide portion 1141. The inner guide portion 1142 is connected to the inner sidewall of the mounting hole 111 and the outer guide portion 1141. The distance between the inner guide portion 1142 and the knife box 12, and the distance between the outer guide portion 1141 and the knife box 12, gradually decrease from the outside to the inside. Herein, from the outside to the inside means from the outside of the mounting hole 111 to the inside of the mounting hole 111.

[0032] The outer guide portion 1141 is positioned at the opening of the mounting hole 111, serving as an initial guide structure. This allows the tool holder 12 to quickly slide into the opening along the outer guide portion 1141 upon contact with the mounting hole 111, reducing the precision required for initial alignment by the user. The inner guide portion 1142 is located between the inner wall of the mounting hole 111 and the outer guide portion 1141, connecting the initial guidance on the outside with precise installation on the inside. After the tool holder 12 is inserted into the mounting hole 111, the inner guide portion 1142 continues to guide the tool holder 12 inward, forming a continuous guide path from the outside to the inside, avoiding mid-way deviation due to insufficient length of a single guide portion. In summary, the outer guide portion 1141 reduces the difficulty for the user to find the hole, while the inner guide portion 1142 guides the insertion accuracy of the tool holder 12. The combination of the two improves the smoothness of the user's tool holder 12 installation operation, allowing the user to complete the installation operation without repeatedly adjusting the angle.

[0033] Furthermore, the distance between the outermost and innermost sides of the inner guide portion 1142 is greater than the distance between the outermost and innermost sides of the outer guide portion 1141.

[0034] The outer guide portion 1141 has a shorter guide surface, which reduces the feeling of obstruction during initial insertion and avoids confusion for the user when searching for the insertion point due to an excessively long outer guide portion 1141. The inner guide portion 1142 has a longer guide surface to provide a continuous and deep guide path, gradually reducing the gap between the knife box 12 and the guide portion, and achieving a transition from rough alignment to precise positioning. In summary, the cooperation between the short outer guide portion 1141 and the long inner guide portion 1142 results in a graded guidance effect during the installation process, which involves rapid insertion followed by precise correction.

[0035] Furthermore, the knife box 12 is detachably connected to the rear wall of the connecting hole 113. The inner guide portion 1142 is provided on the side of the mounting hole 111 away from the protruding hole 112. The inner guide portion 1142 is connected to the rear wall of the mounting hole 111 and the outer guide portion 1141 on both sides in the left-right direction, respectively. The inner guide portion 1142 is connected upward to the upper wall of the mounting hole 111 and downward to the lower wall of the mounting hole 111.

[0036] The connection structure between the tool holder 12 and the tool post 11 is located between the mounting hole 111 and the rear side of the tool post 11 to achieve the effect that the tool holder 12 can be detachably connected to the rear wall of the mounting hole 111. This makes the distance between the mounting hole 111 and the rear side of the tool post 11 designed to be greater than the distance between the top surface of the mounting hole 111 and the top surface of the tool post 11, and the distance between the bottom surface of the mounting hole 111 and the bottom surface of the tool post 11. The inner guide portion 1142 with a longer guide surface is located on the side of the mounting hole 111 away from the protrusion hole 112. This feature can be used to make the tool post 11 structure more compact and avoid the tool post 11 having a large width in the vertical direction, which would make the tool post 11 design bulky.

[0037] Furthermore, the knife box 12 includes an extension portion 122 and a mounting portion 123. The extension portion 122 is disposed on the side of the mounting portion 123. The mounting portion 123 is located inside the mounting hole 111. The extension portion 122 passes through the extension hole 112 and extends out of the extension hole 112. The mounting portion 123 is connected to the hole wall of the mounting hole 111. The first guide portion 114 is disposed at the end of the mounting portion 123 in the left-right direction and is disposed along the edge of the end.

[0038] The mounting part 123 is used to fix the blade box 12 by connecting it to the hole wall, so as to ensure that the blade box 12 remains stable during shaving. A first guide part 114 is provided on the edge of one end to provide physical guidance when installing the blade box 12. The protruding part 122 is used to install the blade, and its exposed design allows the blade to contact the skin to perform the shaving function.

[0039] Furthermore, the first guide portion 114 and the second guide portion 121 are composed of arc surfaces, so as to reduce the rigid contact between the knife box 12 and the mounting hole 111 through the smooth transition of the arc surfaces, thereby reducing the insertion resistance and improving the installation smoothness.

[0040] Furthermore, clearance gaps 13 are provided between the two side walls of the protruding hole 112 and the knife box 12.

[0041] The clearance 13 provides physical buffer space for the movement of the blade box 12. When the blade box 12 moves in the left and right direction, the clearance on both sides can prevent the blade box 12 from directly rubbing or getting stuck with the wall of the extension hole 112, making the operation smoother. In addition, the clearance 13 can also prevent the vibration generated by the shaving operation from causing the blade box 12 to collide or rub against the extension hole 112, ensuring the durability of the parts and extending the service life of the parts.

[0042] Furthermore, the mounting hole 111 and the extension hole 112 extend through the knife holder 11, so that the user can insert and eject the knife box 12 from both sides in the left-right direction.

[0043] Furthermore, the mounting hole 111 and the protruding hole 112 are rectangular holes, and the width of the mounting hole 111 in the vertical direction is greater than the width of the protruding hole 112 in the vertical direction, so that the tool holder 11 has a stepped hole structure, ensuring that the tool box 12 can be stably connected to the mounting hole 111.

[0044] This embodiment also relates to a shaving device, including a handle 2 and the aforementioned razor head 1, wherein the razor head 1 is mounted on the handle 2.

[0045] The shaving device is a razor, and the handle 2 is a long rod-shaped component to facilitate the user's grip and use.

[0046] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0047] Furthermore, detachable connection and detachable setting refer to the ability of two components to be repeatedly assembled and disassembled without damage or severe deformation, including but not limited to fixing by connectors or fixing by snap-fit ​​connections.

[0048] Furthermore, sliding connection and sliding setting refer to the connection between two connected components, where one component can slide along a fixed trajectory on the other component, including but not limited to connection by sliding a slider into a groove, or connection by inserting a slider into a hole whose size and profile match the slider.

[0049] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0050] In summary, this utility model embodiment provides a razor head 1 and a shaving device, the technical effects of which are as follows:

[0051] The razor head 1 of this utility model has a razor holder 11 with a connecting mounting hole 111 and an extension hole 112. Both holes are located on the same side of the razor holder 11 in the left-right direction. The extension hole 112 is located in front of the mounting hole 111 and extends through to the front side of the razor holder 11, allowing the razor case 12 to be inserted into the mounting hole 111 along the side of the razor holder 11 where the mounting hole 111 and extension hole 112 are located, and to extend forward through the extension hole 112 to the outside of the razor holder 11. Furthermore, the razor case 12 is detachably connected to the razor holder 11, so that after being inserted into the mounting hole 111, the razor case 12 is fixed inside the mounting hole 111. When the razor case 12 needs to be replaced, the old razor case 12 can be removed. Furthermore, the mounting hole... One or both of the opening of the mounting hole 111 and one side of the blade holder 12 are provided with guide portions. When the blade holder 12 is inserted into the mounting hole 111, the guide portion abuts against the opening of the mounting hole 111, the guide portion abuts against the edge of one end of the blade holder 12, or the two guide portions abut against each other. By moving along the guide portion, the blade holder 12 is guided into the mounting hole 111, thereby reducing the precision required for inserting the blade holder 12 into the mounting hole 111. In summary, when using the shaver head 1 and shaving device of this utility model, the user does not need to carefully align the blade holder 12 with the mounting hole 111, which can minimize the number of times the user needs to install it repeatedly, thereby making the user's blade replacement operation simpler, more convenient and faster.
