[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that all directional indicators in this utility model embodiment, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0022] like Figure 3 and Figure 5As shown, this utility model provides a gear indicator mechanism, which is mainly used for indicating the rotation gear between a rotating component sleeved on the outside of the main body and the main body. It includes a first positioning component 700 disposed on the main body and a second positioning component 800 disposed on the rotating component. The second positioning component 800 is inserted into the first positioning component, and the two can rotate relative to each other. Rotation can be achieved through a snap-fit ​​mechanism or by bolt fastening. In this embodiment, bolt fastening is used. The rotating component is fixed to the main body using bolts, and due to the smooth surface design between the rotating component and the bolt, the rotating component can rotate relative to the main body. In this embodiment, it is mainly used in a shaver; therefore, the main body can be the shaver body, and the rotating component is a U-shaped or annular protective frame, mainly serving to protect the shaver head assembly.

[0023] The first positioning member 700 has a slot 710 with a positioning block 740, i.e., the positioning block is disposed inside the slot. The second positioning member 800 is inserted into the first positioning member 700 and forms a rotatable engagement, and is provided with a plurality of position grooves 810; that is, the outer surface of the second positioning member is rotatably engaged with the first positioning member, and the inner surface of the second positioning member is provided with a plurality of position grooves, which are four in this embodiment, and are distributed at 0°, 90°, 180° and 270°, thereby realizing the indication of different rotation angles of the protective frame.

[0024] Two positioning blocks are arranged opposite each other. The slot 710 is provided with a U-shaped elastic element 730 fixed to one side, and its two elastic arms respectively overlap with the positioning block 740, so that the positioning block 740 and the positioning groove 810 form a positioning position. The U-shaped elastic element plays the role of supporting the positioning block. At the same time, when the protective frame rotates relative to each other, the U-shaped elastic element can be driven to compress and generate elastic force, and after the external force is released, it drives the positioning block to return to its original position.

[0025] In this embodiment, the U-shaped elastic element is a U-shaped retaining spring or a U-shaped spring sheet. A fixing groove 770 is provided on one side of the slot 710, and the U-shaped elastic element 730 is embedded in the fixing groove 770. That is, the middle section is locked in the fixing groove 770, while the two elastic arms extend to the bottom of the positioning block and apply an outward force to it.

[0026] The rotating component and the main body are rotatably coupled via a rotating shaft assembly, which consists of a copper sleeve 750 embedded in the slot 710 and a bolt 720 for fixing the rotating component and the main body. The bolt is locked to the copper sleeve to ensure a reliable connection between the rotating component and the main body.

[0027] like Figure 2As shown, the slot 710 has a positioning groove 760 with a through hole. The positioning block 740 is slidably disposed within the positioning groove 760. One end of the positioning block 740 has a protrusion 741 that can pass through the through hole. The positioning groove serves to restrict the positioning block. The positioning block is pressed against the positioning groove by a U-shaped elastic element, and its protrusion passes through the through hole and contacts the inner surface of the second positioning element on the outside. When the inner surface contacts the protrusion, it causes the positioning block to move inward against the elastic force. When the gear slot contacts the protrusion, the pressure is released, the U-shaped elastic element returns to its original position, and the protrusion enters the gear slot. The movement of the protrusion along the inner surface of the second positioning element achieves the gear shifting design. At the same time, the U-shaped elastic element allows the positioning block to be pre-installed in the first positioning element, making assembly more convenient and improving production efficiency.

[0028] The other end of the positioning block 740 is provided with a limiting groove for limiting the elastic arm. The limiting groove accommodates the elastic arm, thereby preventing the positioning block from being ejected. It can always ensure that the positioning block is limited in the slot of the first positioning member by the U-shaped elastic member and will not fall out.

[0029] The bottom of the slot 710 is provided with a guide groove 780 that is adapted to the positioning block 740, which serves to guide the sliding of the positioning block.

[0030] like Figure 1 As shown, this utility model also provides a shaver, which includes a shaver body 100, a blade assembly 300 disposed at one end of the shaver body 100, and a control board 600 for controlling the movement of the blade assembly 300. The shaver body 100 includes a housing, which can be made of plastic or metal. The blade assembly and the housing are detachably connected by a snap-fit ​​or magnetic attraction method. The housing is hollow inside, and its upper end is provided with a bracket for supporting a gear set. This bracket encloses the housing to form a sealed space, which can prevent water or stubble from entering the housing. The bottom of the bracket extends to form a mounting bracket. A motor 400 is also provided inside the housing. A battery is disposed on one side of the motor 400 and the control board 600 on the other side. The control board 600 is fixedly mounted on the mounting bracket. When the control board 600 receives a control signal, it drives the blade assembly to move through the motor. This control signal can be triggered by a control switch disposed at any position on the housing. The control switch can be a touch chip, a tactile switch, a Hall sensor, etc.

[0031] In this embodiment, a Hall sensor 610 is used as a control switch to check whether the start signal has been detected. Preferably, a protective frame 200 is provided on the outside of the housing. This protective frame 200 is a ring, semi-ring, or U-shaped frame structure. In this embodiment, a U-shaped frame structure is used. That is, the protective frame is rotatably fitted onto the outside of the shaver body through symmetrically arranged retaining rings or rotating shafts. The structure arranged along the width direction of the shaver body is the cover 220. Its projected area on the horizontal plane covers the entire shaver head assembly, thus protecting the shaver head assembly in the first position. By rotating the protective frame, it can be rotated to a certain angle. By setting a Hall switch at a specific angle, when it is rotated to the set angle, the magnet 210 embedded in the protective frame triggers the Hall switch, thereby driving the shaver head assembly to work.

[0032] To allow the user to better perceive whether the protective frame has rotated to the correct position when it is turned, the aforementioned gear indicator mechanism is provided between the protective frame 200 and the shaver body 100. The gear indicator mechanism consists of two sets, symmetrically arranged on both sides of the shaver body 100, ensuring consistent rotation feel on both sides.

[0033] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
