Abstract
Description
Technical Field
[0001] This application relates to the field of hair clippers, and more particularly to a hair clipper blade. Background Technology
[0002] Hair clippers consist of a blade head and a handle. The blade head is the core component, as it comes into direct contact with the human body to shave hair. Existing hair clippers typically feature an adjustable floating blade on the main blade head. The teeth of the floating blade are staggered with those of the main blade head. The floating blade slides on the main blade head along the direction of its proximity to or distance from the main blade's teeth. Users can adjust the floating blade by moving it using an adjustment mechanism connected to its transmission, thereby adjusting the tooth density to meet different needs.
[0003] In existing technologies, the adjustment components are mostly toggle switches. Users adjust the level of the floating cutter head by toggling the switch. The adjustment direction of the toggle switch is the same as the movement direction of the floating cutter head, which causes the floating cutter head to easily retract when it encounters resistance or impact, resulting in a problem of cutter retraction. Utility Model Content
[0004] To solve the above-mentioned technical problems, this application provides a hair clipper head.
[0005] This application provides a hair clipper head, which adopts the following technical solution:
[0006] A hair clipper head includes a main blade head and a floating blade head. The floating blade head is slidably disposed on the main blade head and moves in a direction close to or away from the blade teeth of the main blade head. An adjusting member is rotatably disposed on the floating blade head, and the adjusting member is used to rotate to drive the floating blade head to slide. The main blade head is also provided with a gear adjustment structure, which is used to adjust the rotation angle of the adjusting member and lock the adjusting member.
[0007] By adopting the above technical solution, the floating cutter head is translated by the rotation of the adjusting component. The direction of movement of the adjusting component is not the same as the direction of movement of the floating cutter head. When the floating cutter head is subjected to resistance or impact, the adjusting component bears part of the force, but does not cause the adjusting component to move, making the floating cutter head more stable during use. The gear adjustment structure can adjust the rotation angle of the adjusting component, thereby adjusting the movement distance of the floating cutter head. The distance between the floating cutter head and the main cutter head is divided into several gears to meet the diverse needs of users. Moreover, the adjusting component can be locked to further improve the locking effect of the floating cutter head and minimize the occurrence of cutter retraction.
[0008] Optionally, it also includes a mounting housing, on which the adjusting member and the floating cutter head are both disposed, and the main cutter head is detachably connected to the mounting housing.
[0009] By adopting the above technical solution, the main cutter head and the mounting housing are set independently, which facilitates the individual maintenance or replacement of the main cutter head and the mounting housing, reduces replacement costs, and the main cutter head and the mounting housing are detachably connected, which facilitates the disassembly and assembly of the adjusting parts and the floating cutter head.
[0010] Optionally, the adjusting component includes a cam disk rotatably mounted on the mounting housing and a transmission assembly slidably mounted on the mounting housing. The cam disk is provided with a transmission block that rotates eccentrically. The transmission block is rotatably connected to the transmission assembly. The floating cutter head is mounted on the transmission assembly. The transmission assembly is used to convert the rotational force of the transmission block into a sliding force to drive the floating cutter head to move.
[0011] By adopting the above technical solution, the rotation of the adjusting component is converted into the linear motion of the floating cutter head through the cam mechanism and transmission assembly. The structure is simple, easy to process, and has a good transmission effect. The transmission assembly is set on the mounting housing, and the floating cutter head is driven to slide through the transmission assembly. The floating cutter head and the transmission assembly are set independently, which facilitates the maintenance and replacement of the floating cutter head or the transmission assembly and reduces the replacement cost.
[0012] Optionally, the transmission assembly includes a transmission plate slidably disposed on the mounting housing. The mounting housing has a guide groove, and the transmission plate has a guide block for inserting into the guide groove and sliding. The transmission plate also has a transmission groove for inserting the transmission block. The transmission plate is used to slide to drive the floating cutter head to slide.
[0013] By adopting the above technical solution, the guide groove guides the guide block, so that the transmission plate moves in a straight line. The guide groove and guide block have simple structures and are easy to process. The transmission plate is connected to the transmission block through the transmission groove, and the transmission effect is good.
[0014] Optionally, both ends of the transmission groove along the sliding direction of the floating cutter head are abutted and clamped onto the transmission block.
[0015] By adopting the above technical solution, clamping the transmission blocks at both ends of the transmission groove can make the response more timely and improve the transmission efficiency. On the other hand, not clamping the transmission blocks at both ends can provide space for rotation and movement.
[0016] Optionally, the mounting housing has a sliding hole that extends along the rotation path of the adjusting member. The adjusting member is slidably disposed within the sliding hole, and the adjusting member includes an operating end that extends out of the mounting housing through the sliding hole.
[0017] By adopting the above technical solution, the sliding hole can limit the rotation path of the adjusting component, and the operating end extends out of the mounting housing, making it convenient for users to rotate the adjusting component.
[0018] Optionally, the gear adjustment structure includes multiple adjustment slots formed on the mounting housing and adjustment blocks provided on the adjustment member. The multiple adjustment slots are distributed around the rotation axis of the adjustment member, and the adjustment blocks are used to be inserted into different adjustment slots to lock the rotation angle of the adjustment member.
[0019] By adopting the above technical solution, the rotation angle of the adjusting component can be changed by inserting the adjusting block into different adjusting slots, and the insertion and engagement of the adjusting block and the adjusting slot can lock the adjusting component, so that the adjusting component is fixed at a certain position.
[0020] Optionally, a guide surface is formed on the adjusting groove and / or the adjusting block, the guide surface being used to guide the adjusting block to slide out of the adjusting groove.
[0021] By adopting the above technical solution, the guide surface facilitates the unlocking of the adjustment component, making operation convenient.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. Elastic components greatly enhance the rebound performance of the sole;
[0024] 2. The snap-fit design facilitates the installation of flexible components, minimizing deformation of the snap-fit groove during the snap-fit process;
[0025] 3. The telescopic sleeve and the fixed sleeve limit and guide the spring, providing a good guiding effect and allowing the spring to be hidden inside the sleeve, thus providing a certain degree of protection for the spring. Attached Figure Description
