Abstract
Description
Technical Field
[0001] This utility model relates to the field of shaver technology, specifically to an electric shaver with a U-shaped protective cap. Background Technology
[0002] Electric shavers are classified into two types based on the blade's movement: rotary and reciprocating. The former has a simpler structure, lower noise, and moderate shaving force; the latter has a more complex structure, higher noise, but stronger shaving force and higher sharpness.
[0003] Existing electric shavers with protective covers for the shaver head face the following problems: the protective cover has a single function, is generally a separately detachable shaver head cover, and adopts a split design. It needs to be removed when in use, and if it is not replaced in time after use, it is easy to lose. Therefore, this utility model proposes an electric shaver with a U-shaped protective cover to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an electric shaver with a U-shaped protective cover, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an electric shaver with a U-shaped protective cover, including a core assembly, a main body shell installed on the outside of the core assembly, a blade assembly installed on the top of the core assembly, side decorative pieces fixedly provided on both sides of the core assembly, and a movable protective component provided between the two side decorative pieces, the movable protective component being used to cover and protect the blade assembly.
[0006] Preferably, the active protection component includes a U-shaped protective cover disposed between two side decorative pieces. A rotating shaft is fixedly installed on both sides of the inner wall of the U-shaped protective cover. A rotating hole for cooperating with the rotating shaft is opened on the outer side of each of the two side decorative pieces. A magnet is embedded and fixed on the upper part of the inner wall of the U-shaped protective cover.
[0007] Preferably, after the U-shaped protective cover is placed over the cutter head assembly, the cutter head assembly is attracted by the magnet to achieve automatic positioning of the U-shaped protective cover.
[0008] Preferably, a Hall switch for use with a magnet is provided below the movement assembly, and a rubber protrusion for limiting the U-shaped protective cover is provided below the main body shell.
[0009] Preferably, when the U-shaped protective cover is rotated to the bottom of the main body shell, it is limited by the rubber protrusion, and when the magnet approaches the Hall switch, it controls the Hall switch to turn on.
[0010] Preferably, a charging port is provided at the bottom of the main body shell.
[0011] Beneficial effects
[0012] This invention provides an electric shaver with a U-shaped protective cap. Compared with the prior art, it has the following advantages:
[0013] This electric shaver with a U-shaped protective cover allows the cover to rotate 360 degrees around the shaver head assembly, thanks to the cooperation of the rotating shaft and rotating hole. When the U-shaped cover is placed on top of the shaver head assembly, it is magnetically attracted to the assembly, thus automatically positioning the cover and protecting it from external impacts. The U-shaped cover and the shaver head assembly are integrated into one piece, solving the problem of traditional shaver head protective covers being easily lost or dropped. Furthermore, the shaver automatically starts when the U-shaped cover is flipped over, making it highly convenient to use. Attached Figure Description

Detailed Implementation
[0018] 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.
[0019] Please see Figures 1-3 The present invention provides the following technical solution: an electric shaver with a U-shaped protective cover, including a core assembly 1, a main body shell 2 installed on the outside of the core assembly 1, a blade head assembly 3 installed on the top of the core assembly 1, side decorative pieces 4 fixedly provided on both sides of the core assembly 1, a movable protective component 5 provided between the two side decorative pieces 4, the movable protective component 5 being used to cover and protect the blade head assembly 3, and a charging interface 8 provided at the bottom of the main body shell 2.
[0020] In this embodiment, the active protection component 5 includes a U-shaped protective cover 51 disposed between two side decorative pieces 4. A rotating shaft 52 is fixedly installed on both sides of the inner wall of the U-shaped protective cover 51. A rotating hole 53 that cooperates with the rotating shaft 52 is opened on the outer side of both side decorative pieces 4. A magnet 54 is embedded and fixed on the upper part of the inner wall of the U-shaped protective cover 51.
[0021] With the cooperation of the rotating shaft 52 and the rotating hole 53, the U-shaped protective cover 51 can rotate 360 degrees around the core assembly 1. The cutter head assembly 3 is made of iron. Therefore, when the U-shaped protective cover 51 is placed on top of the cutter head assembly 3, the cutter head assembly 3 is attracted by the magnet 54 to achieve automatic positioning of the U-shaped protective cover 51, thereby protecting the cutter head assembly 3 from external impact damage.
[0022] In this embodiment, a Hall switch 6 is provided below the mechanism assembly 1 to cooperate with the magnet 54, and a rubber protrusion 7 is provided below the main body shell 2 to limit the U-shaped protective cover 51. When the U-shaped protective cover 51 rotates to the bottom of the main body shell 2, it is blocked and limited by the rubber protrusion 7. When the magnet 54 approaches the Hall switch 6, it controls the Hall switch 6 to open. The rubber protrusion 7 is fixed at the front and rear of the U-shaped protective cover 51, which can initially limit the U-shaped protective cover 51, so that the magnet 54 can stably approach the Hall switch 6. At this time, the Hall element inside the Hall switch 6 will sense the magnetic field. When the magnet 54 approaches, the magnetic field strength reaches the threshold, and the switch outputs a level signal, which can then control the opening of the motor inside the mechanism assembly 1. At the same time, traditional push-button quick-close and indicator lights are also retained on the side of the mechanism assembly 1, which can simultaneously control the product's opening and closing.
