In a preferred embodiment of the present invention, the main magnetic attraction component is mounted in a central area of a central axis of the electric shaver, and the auxiliary magnetic attraction component is disposed around the main magnetic attraction component.
The main magnetic attraction component is assembled in the central area, so that the magnetic attraction force of the lower shell and the upper shell in the central area of the contact surface is ensured, the design is convenient for the quick suction connection of the lower shell and the upper shell, and the action of stabilizing the connection force of the lower shell and the upper shell can be started; the subassembly of will assisting magnetism simultaneously centers on the subassembly setting is inhaled to main magnetism, in concrete use, when guaranteeing that the edge of going up the casing contacts casing down, just probably because the existence of subassembly is inhaled to supplementary magnetism has the suction force, can guide the casing assembly of going up on the casing down, and two magnetism inhale the subassembly and work jointly, and the effect of magnetism is strengthened, can fix a position the assembly fast.
In a preferred embodiment of the present invention, the main magnetic attraction assembly comprises a driving magnet embedded in the lower housing and a driven magnet embedded in the upper housing, wherein the magnetism of the driving magnet corresponding to the longitudinal direction of the driven magnet is in a state of opposite attraction;
the auxiliary magnetic attraction component comprises a lower auxiliary magnet and an upper auxiliary magnet, wherein the lower auxiliary magnet is arranged adjacent to the driving magnet, the upper auxiliary magnet is arranged adjacent to the driven magnet, and the magnetism corresponding to the longitudinal direction of the lower auxiliary magnet and the upper auxiliary magnet is in a state of opposite attraction.
In the scheme, the main magnetic attraction component is provided with 2 magnetic attraction components, and the auxiliary magnetic attraction component is provided with 2 magnetic attraction components for detailed description, and the magnetic attraction effect is stronger because the driving magnet and the driven magnet are in opposite attraction states, and the lower auxiliary magnet and the upper auxiliary magnet are in opposite attraction states.
In a preferred embodiment of the present invention, the driving magnet and the driven magnet are integrally injection molded, and the surface of the driving magnet and the surface of the driven magnet include at least two sections, and the magnetic properties of two adjacent sections on the same surface are different.
In the scheme, the driving magnet and the driven magnet are similar in structure, and in order to realize that the driving magnet and the driven magnet can synchronously rotate in a working state, the surfaces of the driving magnet and the driven magnet comprise at least two subareas, and the magnetism of two adjacent subareas on the same surface is different, namely the N pole and the S pole are arranged adjacently; if 3 partitions are provided, the partitions can be N poles, S poles, N poles or S poles, N poles and S poles;
the number of the N poles and the number of the S poles are equal when the number of the partitions is even; when the number of the partitions is odd, the N pole is one more than the S pole, or the S pole is one more than the N level; the concrete conditions are determined according to actual conditions.
However, since the driven magnet works under the magnetic conduction effect of the driving magnet, when the electric shaver is static and is placed longitudinally, the magnetism of the driving magnet corresponding to the driven magnet in the longitudinal direction is in a state of opposite attraction, that is, when the driving magnet is divided into sections corresponding to the N poles, the driven magnet is divided into sections corresponding to the S poles in the longitudinal direction; when the driving magnet partition corresponds to the S pole, the driven magnet partition corresponds to the N pole in the longitudinal direction, and the design ensures that the driving magnet and the driven magnet can synchronously rotate.
In a preferred embodiment of the present invention, the driving unit includes a motor, the motor is connected to the driving magnet, the motor rotates to drive the driving magnet to rotate synchronously, and the moving blade unit is driven to rotate under the action of the motor, the driving magnet and the driven magnet.
As can be seen from the above description, since the driving magnet and the driven magnet are both in opposite attraction, the driving magnet inevitably drives the driven magnet to rotate in the rotating process of the driving magnet, wherein the driven magnet is arranged in the upper shell, and the moving blade unit is also arranged in the upper shell, so that the moving blade unit is known to be driven to rotate under the action of the motor, the driving magnet and the driven magnet according to the force conduction, and the moving blade unit can trim the hair of the human body; this assembly structure is convenient to be dismantled last casing and lower casing, is convenient for wash the drive unit rivers of last casing, improves the convenience of use.

However, since the driven magnet works under the magnetic conduction effect of the driving magnet, when the electric shaver is static and is placed longitudinally, the magnetism of the driving magnet corresponding to the driven magnet in the longitudinal direction is in a state of opposite attraction, that is, when the driving magnet is divided into sections corresponding to the N poles, the driven magnet is divided into sections corresponding to the S poles in the longitudinal direction; when the driving magnet partition corresponds to the S pole, the driven magnet partition corresponds to the N pole in the longitudinal direction, and the design ensures that the driving magnet and the driven magnet can synchronously rotate.
Example 2:
in addition to the active magnetic component and the auxiliary magnetic component disclosed in embodiment 1, this embodiment further describes the structure associated with other components.
Referring to fig. 7 and 8, the driving unit includes a motor 100, the motor 100 is connected to the driving magnet 300, the motor rotates to drive the driving magnet to rotate synchronously, and the moving blade unit E is driven to rotate by the motor 100, the driving magnet 300 and the driven magnet 400.

In the specific working process, the lower magnet fixing shell and the driving magnet are driven to rotate together, and the upper magnet fixing shell and the driven magnet are driven to rotate together; the arrangement of the magnet fixing shell can protect the driving magnet and the driven magnet from reducing the magnetic force performance caused by magnet abrasion and reducing the service life in the long-time rotating process; and secondly, the motor is directly connected with the lower magnet fixing shell, namely, the kinetic energy of the motor indirectly acts on the driving magnet.
Example 2:
the auxiliary magnetic attraction component and the main magnetic attraction component are adopted in the embodiments 1 and 2.
Furthermore, the magnetic attraction force of the auxiliary magnetic attraction component is smaller than that of the main magnetic attraction component. As can be seen from the above description, the upper casing and the lower casing are connected in an attracting manner, and if the connection is performed only by means of the magnetic attraction of the main magnetic attraction component, the magnetic attraction of the main magnetic attraction component needs to be adjusted to be large to ensure good magnetic attraction, but because the driving magnet in the main magnetic attraction component is connected with the motor, if the magnetic attraction of the driving magnet and the driven magnet is too large, if the motor wants to drive the driving magnet to rotate, the overall load of the motor is inevitably too heavy, or a motor with high rotation speed is adopted, the cost of the mode is greatly increased; or the motor load is large, which affects the service life of the normal motor;
in conclusion, the magnetic attraction force of the driving magnet and the driven magnet in the main magnetic attraction component is reduced, the reduced magnetic attraction force is transferred to the auxiliary magnetic attraction component, the reduced magnetic attraction force is compensated through the auxiliary magnetic attraction component, and the lower auxiliary magnet and the upper auxiliary magnet of the auxiliary magnetic attraction component are in static fixed connection, so that the upper shell and the lower shell can be in magnetic attraction connection, the dependence on the magnetic attraction force of the main magnetic attraction component is reduced, the whole machine load of the motor can be further reduced, the motor can be selected more conveniently, and the motor can be adapted to motors of various models;
the magnetic attraction force of the auxiliary magnetic attraction component is further smaller than that of the main magnetic attraction component, and if the magnetic attraction force of the auxiliary magnetic attraction component is larger than that of the main magnetic attraction component, the whole motor is overloaded; if the magnetic attraction force of the auxiliary magnetic attraction component is too large, the motor overcomes the friction force of the corresponding areas of the driving magnet and the driven magnet and the friction force of the contact surfaces of the corresponding areas of the lower auxiliary magnet and the upper auxiliary magnet, and the whole load of the motor is heavier under the condition that the friction force of the areas which are not connected with the motor is larger; in summary, the magnetic attraction force of the auxiliary magnetic attraction assembly needs to be smaller than the magnetic attraction force of the main magnetic attraction assembly in the design process.
In order to realize assembly better, the main magnetic component and the auxiliary magnetic component both adopt annular magnets, and the thickness of the magnet corresponding to the annular magnet of the main magnetic component is larger than that of the magnet corresponding to the annular magnet of the auxiliary magnetic component.
The structure of the annular magnet is convenient to install, and the magnetic force line cannot be cut off, so that a relatively finished attraction force is formed, and the assembly of the upper shell and the lower shell is facilitated;
as can be seen from the above, the main magnetic attraction component is a driving rotary magnetic attraction, and the magnetic force line needs to pass through the lower shell, the upper shell and other components, and if the thickness is low, a good magnetic attraction force cannot be achieved.

As shown in fig. 9, the central axis of the motor is offset from the central axis of the electric shaver by 4-8 mm. In order to prevent water from entering the shell to influence the service life of the magnets in the process of cleaning the electric shaver, the driving magnets and the driven magnets are respectively coated through the lower shell and the upper shell for protection, in the specific working process, the driving magnets are driven by the rotation of a motor to rotate at a high speed, the driven magnets which are in magnetic attraction connection with the driving magnets are driven to rotate by the high-speed rotation, the motor can be fixed through a motor support to prevent vibration due to the fact that the rotating speeds of the two magnets are related to the rotating speed of the motor, the two magnets are fixed through a magnet fixing shell, but the magnet fixing shell is not in direct physical connection with the shell, and the magnets vibrate during the rotating process; the driving magnet and the driven magnet are arranged at the central axis of the electric shaver, and vibration is generated at the central axis and in the gravity center area, so that the vibration is counteracted with other components, the vibration influence is lowest, and the rotating stability of the two magnets is guaranteed.
Firstly, the motor for providing power for the driving magnet is eccentrically arranged compared with the central axis of the electric shaver, namely, the driving shaft of the motor is not placed at the central axis of the electric shaver, so that the motor can be placed at will according to the design space, and the convenience of design is improved; secondly, if the distance between the central axis of the motor and the central axis of the electric shaver is less than 4mm, the motor can generate certain vibration in the rotating process, and the driving magnet positioned at the central axis of the electric shaver can be influenced to a certain extent due to the too close distance, so that the driving magnet is not beneficial to work; if the distance between the central axis of the motor and the central axis of the electric shaver is larger than 8mm, the installation space of the lower shell is too large, so that the electric shaver is inconvenient to hold.
