Description

Tool bit subassembly and razor
Technical Field
The utility model relates to the field of articles for daily use, in particular to a cutter head assembly and a shaver.
Background
The structure of the shaver generally comprises a body, a machine head and a cutter head assembly, wherein the cutter head assembly comprises a cutter mesh, a movable blade and the like. In order to facilitate cleaning, the cutter mesh, the movable blade and the machine body are detachably connected, and after the cutter mesh is detached, the motor in the machine body can still be started, so that when the movable blade is not detached after the cutter mesh is detached, once the motor is started by careless misoperation, the motor can drive the movable blade to rotate at a high speed, and due to the lack of protection of the cutter mesh, the movable blade can fly out directly to generate unexpected injury accidents.
At present, most coping methods are that a safety switch which can be matched with a cutter mesh is arranged on a machine body, when the cutter mesh is assembled in place, the cutter mesh is contacted with the safety switch, so that a circuit is communicated, a motor can be started, if the cutter mesh is assembled in place, the safety switch is not operated, the circuit cannot be communicated, and the motor cannot be started, so that safe disassembly is ensured.
For example, chinese patent application "a safety locking device for a cutter head cover", application number: CN201620939505.9 discloses that a guide frame is arranged on the inner side wall of the housing, a push rod is arranged in the guide frame in a sliding way, the lower end of the push rod is fixedly provided with a movable press contact piece, the movable press contact piece is in contact fit with a circuit board fixedly arranged in the housing, the upper end of the push rod is propped against a net cover, when the net cover is not assembled in place, a power supply cannot be conducted, and a motor cannot drive a cutter head to rotate.
However, by adopting the scheme, the cutter head assembly is not only provided with a plurality of parts and is inconvenient to assemble, but also high in cost, so that a cutter head assembly which can effectively prevent accidents and is simple in structure is urgently needed. There is thus a chinese patent application "a cutter head assembly, a shaver and a hair bulb trimmer", application number: CN20192156780.8; the cutter head assembly comprises a cutter net, a movable cutter bracket and a movable cutter blade, wherein the cutter net comprises a net surface and a fixed mounting ring, and a circle of annular mounting groove is formed in the inner wall of the fixed mounting ring; the edge of the movable cutter bracket is provided with a plurality of elastic limiting pieces which are uniformly distributed in the circumferential direction, and the movable cutter bracket is installed in the cutter mesh through limiting cooperation of the elastic limiting pieces and the annular installation groove. The movable knife bracket has the advantages that the movable knife bracket is axially limited and matched with the annular mounting groove of the knife net through the elastic limiting piece, so that the movable knife bracket and the movable knife blade can be removed simultaneously when the knife net is disassembled, the safety accident that the motor drives the movable knife bracket to fly out is avoided, and the movable knife bracket is simple in structure and convenient to assemble, and a safety switch and the like are omitted.
However, in the above patent application, in order to achieve synchronous disassembly of the blade net, the movable blade carrier and the movable blade, an elastic limiting member is newly added, and then the elastic limiting member is newly added during assembly. Although the assembly of the elastic limit piece is not complex, it is an additional assembly step. Accordingly, there remains room for further improvement in existing cutter head assemblies.
