[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] refer to Figure 1 The blade head of the electric shaver provided in the embodiment of the present application includes: a blade head housing and a blade head support, and a blade disc arranged between the blade head housing and the blade head support. In the specific setting, a drive shaft driven by a motor is passed through the blade head support, and the drive shaft is connected to the blade disc. When the motor is started, the drive shaft can drive the blade disc to rotate circumferentially. In addition, a blade net is arranged on the blade head housing, and the blade net can allow the beard to enter the inside of the blade head housing when it fits the face of the person, so that the rotating blade disc cuts off the beard to achieve shaving.

[0029] refer to Figure 1 and Figure 2 In some embodiments, a first clamping member is disposed on the inner wall of the cutter head housing. A second clamping member is disposed on the outer wall of the cutter head support. The first clamping member and the second clamping member are configured to be able to engage with each other so as to connect and fix the cutter head housing and the cutter head support. Compared with the method of connecting with screws, such a configuration can realize convenient installation between the cutter head housing and the cutter head support, which is conducive to improving production efficiency.

[0030] refer to Figure 1 and Figure 2 In some embodiments, the first clamping member is a protrusion and the second clamping member is a slot. In specific use, the first clamping member can be inserted into the second clamping member, thereby achieving the engagement of the first clamping member and the second clamping member. It should be understood that in specific settings, the cutter head bracket and / or the cutter head housing can have a certain elasticity, so that the first clamping member and the second clamping member can be engaged or disengaged.

[0031] Alternatively, in other embodiments, the first clamping member is a clamping groove, and the second clamping member is a protrusion.

[0032] refer to Figure 2 In some embodiments, the first clamping member is a circular protrusion, and the first clamping member is arranged around the circumference of the cutter head housing. This arrangement allows the second clamping member to be engaged with the first clamping member at any position in the circumference. Therefore, when the cutter head housing and the cutter head bracket are assembled, there is no need to adjust the position of the clamping groove or the protrusion, which is conducive to improving the assembly efficiency.

[0033] refer to Figure 2 and Figure 3 In some embodiments, the second clamping member includes a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion are staggered along the circumference of the cutter head support, and the first limiting portion and the second limiting portion are respectively located on opposite sides of the protrusion when clamped ( Figure 1 The first limiting part and the second limiting part are the upper and lower surfaces of the protrusion in the middle. In specific use, the first limiting part and the second limiting part serve as the two side walls of the card slot respectively, and the first limiting part and the second limiting part can limit the axial movement of the first clamping part relative to the second clamping part along the cutter head bracket, thereby achieving the fixation of the cutter head housing and the cutter head bracket. In addition, since the first limiting part and the second limiting part are staggered along the circumference of the cutter head bracket, the force on the cutter head bracket in the circumferential direction is more uniform, thereby avoiding stress concentration.

[0034] In some embodiments, there are multiple second clamping members, and the multiple second clamping members are spaced apart along the circumference of the cutter head support. This arrangement can improve the connection strength between the cutter head support and the cutter head housing and ensure the reliability of the structure. Figure 2 and Figure 3 As shown, this embodiment shows that the number of the second clamping parts is two, and the two second clamping parts are respectively located on the opposite sides of the cutter head bracket.

[0035] In some embodiments, the cutter head support is provided with a cantilever arm, the second clamping member is provided on the cantilever arm, the cantilever arm is provided to be able to swing along the radial direction of the cutter head support, and has a first position and a second position relative to the cutter head support, in the first position, the second clamping member is engaged with the first clamping member, and in the second position, the second clamping member is disengaged from the first clamping member. This arrangement can realize the engagement and disengagement between the first clamping member and the second clamping member, thereby realizing the loading and unloading between the cutter head housing and the cutter head support.

[0036] In some embodiments, a groove is formed on the side wall of the cutter head support, and the cantilever arm is located in the groove, and one end of the cantilever arm is connected to the side wall of the groove, and the other end is cantilevered. When subjected to external force, the cantilevered end of the cantilever arm can swing along the radial direction of the cutter head support to enter or exit the groove. This arrangement can prevent the cantilever arm from protruding from the outer wall of the cutter head support and affecting assembly. It should be understood that the above-mentioned manner of arranging the cantilever arm is only an example and does not constitute a limitation of the present application.

[0037] In some embodiments, the cantilever arm can be configured to remain in the first position when not subject to external force. That is, the cantilever arm has a certain elasticity, and the elasticity can cause the cantilevered end of the cantilever arm to have a tendency to swing outward from the groove. Specifically, when subjected to external force, the cantilever arm can swing along the radial direction of the cutter head holder into the groove so that the second clip reaches the second position. When the external force disappears, the cantilever arm can swing along the radial direction of the cutter head holder to exit the groove so that the second clip reaches and remains in the first position. This configuration can prevent the first clip and the second clip from being released prematurely during use, thereby causing the cutter head housing and the cutter head holder to separate, affecting the reliability of the structure and the safety of use.

[0038] In some embodiments, the cantilever arm can be configured to allow the user to swing it in the radial direction of the cutter head support when engaged. That is, in the assembled state, at least part of the structure of the cantilever arm is exposed to the outside, so that the user can apply external force to the cantilever arm to swing it in the radial direction of the cutter head support. This configuration can facilitate the user to release the engagement of the first clamping member and the second clamping member, thereby separating the cutter head housing and the cutter head support.

[0039] According to the above scheme, the blade housing and the blade support of the electric shaver are connected by snap-fitting. Compared with the method of connecting with screws, this can realize convenient installation between the blade housing and the blade support, which is conducive to improving production efficiency.

[0040] An embodiment of the present application also provides an electric shaver, comprising a handle and a shaver head.

[0041] According to the above scheme, the blade housing and the blade support of the electric shaver are connected by snap-fitting. Compared with the method of connecting with screws, this can realize convenient installation between the blade housing and the blade support, which is conducive to improving production efficiency.

[0042] In some embodiments, the cutter head and the handle are connected by magnetism. That is, one of the cutter head and the handle is provided with a first magnetic member, and the other is provided with a second magnetic member, and the cutter head and the handle are adsorbed and connected by the first magnetic member and the second magnetic member. This arrangement can facilitate the loading and unloading between the cutter head and the handle, which is beneficial to improving production efficiency. It should be understood that in the specific arrangement, both the first magnetic member and the second magnetic member can be magnets, or one of the first magnetic member and the second magnetic member is a magnet, and the other is a metal component in the cutter head or the handle, such as a cutter head bracket or a cutter head housing.
