Description

Technical Field

[0001] This utility model relates to a detachment structure for a plucking tool head, and particularly to an automatic detachment structure for a plucking tool head, belonging to the field of plucking tool technology. Background Technology

[0002] Currently, most hair removal devices on the market have a complex removal mechanism consisting of multiple components such as a slide and a button. The connection between the blade and the removal mechanism is located near the center of the main body, resulting in poor stability of the connection. Existing removal blades are typically pulled out by pressing the removal button and then directly pulling the blade out. Because the blade and body have a seamless fit, and the blade's round, smooth surface makes it difficult to grip. This means that even when the button is pressed, it's difficult to effectively hold the blade and pull it out.

[0003] For example, the publication number is CN 221711411 U, the application number is CN2023236688945, and the invention title is: A straight-press type reverse-direction operation hair removal structure hair removal device. The hair removal structure of the above patent includes a button, a rocker, a sliding plate, and a connecting plate. The structure is relatively complex. The rocker seat is located near the middle of the main body, making the connection between the connecting plate and the main body not completely stable. After pressing the button, the blade does not automatically pop out and needs to be pulled out with effort. It is inconvenient to change different blades and cannot meet customer needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology, such as complex structure, incomplete and unstable connection, difficulty in pulling out the blade, and inconvenience in replacing different blades. This invention provides an automatic detachment structure for the blade of a hair removal device, which simplifies the structure, ensures a stable connection, makes it easy to pull out the blade, and makes it very convenient to replace different blades.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic removal structure for a hair removal tool head, comprising a main body and a head assembly, wherein the head assembly is inserted into the upper end of the main body and tightly connected; a motor and a motor shaft extending forward from the motor are provided inside the main body, and an eccentric wheel is fixedly connected to the front end of the motor shaft, wherein the eccentric wheel drives the head assembly to work through the eccentric shaft;

[0006] It also includes a double-arm cutter head release button, a top block, a top block spring, and a seat support; the seat support is disposed between the cutter head assembly and the machine body.

[0007] The cutter head assembly has one cutter head hook on each of its two lower sides; the double-arm cutter head release button includes a button in the middle of the upper end and symmetrically arranged arms on both sides, with a hook locking position in the middle of each arm; a sleeve post is provided at the front of each arm, and a return spring is provided on the sleeve post; the double-arm cutter head release button is inserted between the machine body and the base, and the cutter head hook passes through the base and engages with the hook locking position;

[0008] The top block is vertically positioned between the base and the upper surface of the motor; the base has a through hole, and a top block limiting ring is fixedly installed in the middle of the top block; the upper end of the top block extends upward from the through hole, and the lower end of the top block passes through the top block spring and rests against the upper surface of the motor; when the cutter head assembly and the main body are combined, the cutter head hook and the hook locking position are in a locked state, and the top block spring is in a compressed state;

[0009] When the button is pressed, the two side arms insert a certain distance, and when the two cutter head hooks are completely disengaged from their respective hook positions, the top block, under the restoring force of the top block spring, pushes the cutter head assembly upward.

[0010] This allows for easy removal of the blade head, separating the blade head assembly from the main body and thus solving the problem of the blade head being difficult to remove.

[0011] When the button is pressed down, the top block is pushed upwards. The top block limiting ring moves up to below the seat and can no longer move upwards, thus limiting the distance the top block can move.

[0012] Under the restoring force of the top block spring, the top block lifts the cutter head assembly upwards by a distance of 1-3 mm.

[0013] Under the restoring force of the top block spring, the top block lifts the cutter head assembly upwards by a distance of 2 mm.

[0014] The support is a concave support, and the shape of the interior of the concave support matches the lower part of the cutter head assembly; the eccentric wheel passes through the support and connects with the cutter head assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the designed double-arm blade removal button is an integral unit, which simplifies the structure; it has two side arms, which makes insertion and installation convenient; the blade assembly is firmly connected to the removal structure, which increases the reliability of use; it is equipped with a top block and top block spring assembly structure, which can automatically spring up when the button is pressed, so that the blade can be easily removed and the blade assembly can be separated from the main body, thereby solving the problem of the blade being difficult to remove.
