[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] Electric shavers currently on the market often use switches in the form of inductive touch or mechanical touch to control the on and off of the circuit and thus control the start and stop of the motor. However, the mechanical touch method is relatively traditional, and after long-term use, the structure is damaged, resulting in inflexible switches; the inductive touch method often causes the shaver to be started due to accidental touch by the user, and the control method is unstable.

[0033] In view of this, the utility model provides a magnetically controlled shaver. Figure 1-4 For an embodiment of the magnetically controlled shaver provided by the utility model, please refer to Figure 1-4The shaver 100 comprises a main body 1 , a cutter head assembly 2 and a protective cover 3 .

[0034] The main body 1 includes a shell 11, a drive assembly 12 and a circuit board 13. A fixing structure is provided in the shell 11 so that the drive assembly 12 and the circuit board 13 are fixedly installed in the shell 11. The blade assembly 2 is installed in the main body 1, that is, it is provided in the shell 11 and is connected to the drive assembly 12. The protective cover 3 is provided in the shell 11 and only covers a part of the shell 11. The protective cover 3 is provided with a magnetic part 31, and a reed switch 14 is provided in the shell 11, which is used to turn off or start the drive assembly 12 when the magnetic part 31 approaches or moves away from the reed switch 14. It should be noted that the reed switch 14 is also called a reed switch, which is an electric switch operated by an applied magnetic field. The magnetizable reeds overlapping at the two ends of the reed switch are sealed in a glass tube, and the function of the reed is equivalent to a magnetic flux conductor. When in the magnetic field generated by the magnetic member 31 (permanent magnet or electromagnetic coil), the external magnetic field causes the two reeds to have the same polarity near their end points. When the magnetic force exceeds the elastic force of the reeds themselves, the two reeds will separate and disconnect the circuit. When the magnetic field weakens or disappears, the two reeds will be released due to their own elasticity, and the contact surfaces will touch to connect the circuit.

[0035] In the technical solution of the utility model, a magnetic member 31 is provided in the protective cover 3 and a reed switch 14 is provided in the housing 11. When the protective cover 3 approaches or moves away from the housing 11, that is, the magnetic member 31 approaches or moves away from the reed switch 14, the driving assembly 12 is turned off or started. The control method of the shaver 100 is simple and reliable, and the shaver can respond sensitively even after long-term use.

[0036] To install the blade assembly 2, refer to Figure 1-3 In one embodiment of the utility model, the housing 11 includes a mesh head seat 112, and the cutter head assembly 2 is installed in the mesh head seat 112. In addition, the housing 11 also includes a base 113 for installing the drive assembly 12 and the circuit board 13. The mesh head seat 112 and the base 113 are detachable to facilitate the removal of the cut hair in the housing 11. The mesh head seat 112 and the base 113 are connected by means of snap connection, magnetic adsorption, etc.

[0037] For further information, see Figure 1-3 In one embodiment of the utility model, the cutter head assembly 2 includes a moving cutter (not shown in the figure) and a mesh cover 21. The moving cutter is rotatably mounted in the mesh head seat 112, and the mesh cover 21 is fixedly mounted on the mesh head seat 112 and exposed to the outside. The driving assembly 12 is a micro motor, which drives the moving cutter, and the mesh cover 21 is elastically arranged on the mesh head seat 112 to make it float up and down and move closer to or away from the moving cutter, thereby completing the shaving action.

[0038] To prevent the cutter head assembly 2 from being damaged due to collision, please refer to Figure 1-3 In one embodiment of the present invention, the protective cover 3 is installed on the mesh head seat 112, that is, it is covered outside the mesh head seat 112 to protect the cutter head assembly 2. It should be understood that the protective cover 3 can be connected to the housing 11 (the mesh head seat 112 or the base 113) by means of snap connection, magnetic adsorption, etc.

[0039] To facilitate the reed switch 14 to connect or disconnect the circuit, please refer to Figure 1-3 In one embodiment of the utility model, one end of the reed switch 14 is disposed near the mesh head seat 112, preferably facing the magnetic member 31. When the protective cover 3 is close to the mesh head seat 112 of the housing 11, the magnetic force of the reed of the reed switch 14 is enhanced, and the reed switch 14 is connected to the circuit and drives the motor to work under the action of the magnetic force to shave; when the protective cover 3 is away from the mesh head seat 112 of the housing 11, the magnetic force is weakened, and the reed switch 14 disconnects the circuit and stops the motor.

[0040] It should be noted that the two ends of the reed switch 14 are electrically connected to the mesh cover 21 and the circuit board 13 respectively. When the reed switch 14 is connected to the circuit under the action of magnetic force, the human hand and the skin area to be shaved touch the housing 11 and the mesh cover 21 of the cutter head assembly 2 respectively, so that the current of the power supply passes through the reed switch 14, the mesh cover 21, the human body and the housing 11 in sequence, the housing 11 is electrically connected to the circuit board 13 and energizes the circuit board 13, and at the same time the circuit board 13 controls the drive assembly 12 to start, thereby achieving shaving.

[0041] To facilitate the installation of magnetic element 31, please refer to Figure 1-4 In one embodiment of the utility model, the protective cover 3 includes a cover body 32 and a mounting frame 33 arranged in the cover body 32. The mounting frame 33 is provided with a mounting groove 331 arranged toward the mesh head seat 112 for installing the magnetic member 31. After the magnetic member 31 is fixed to the mounting member, the mounting frame 33 is clamped and fixed in the cover body 32.

[0042] To enhance the effect of the magnetic field of the magnetic member 31 on the reed switch 14, please refer to Figure 1-3 In one embodiment of the present invention, the magnetic member 31 and the reed switch 14 are arranged opposite to each other.

[0043] To fix the magnetic member 31, in one embodiment of the present invention, the inner groove wall of the mounting groove 331 is provided with ribs (not shown) extending in the axial direction, where the axial direction is the axial direction of the driving shaft of the driving assembly 12. Of course, the mounting groove 331 can also be set to other shapes, and considering the magnetic field distribution of the magnetic member 31, a circular groove is preferred.

[0044] Furthermore, in one embodiment of the present invention, the magnetic member 31 and the mounting groove 331 are interference fit, and the interference fit can make the magnet installation more secure. Of course, the implementation of the present invention is not limited to this, and the magnetic member 31 can also be bonded into the mounting groove 331, and the gluing method is also secure. Alternatively, the magnet can be installed by combining gluing and interference fit.

[0045] Preferably, the mounting frame 33 is made of plastic material, which will not interfere with the magnetic field distribution of the magnetic member 31. Furthermore, the magnetic member 31 is a permanent magnet, and its magnetic properties can be maintained for a long time.

[0046] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
