An electric shaver according to a preferred embodiment of the present utility model, which includes a handle portion 10 and a cutter portion 20 mounted to the handle portion 10, will be disclosed and described in the following description with reference to fig. 1 to 7 of the drawings accompanying the description of the present utility model.

Specifically, referring to fig. 1 to 6, the hand-held part 10 includes a housing 11 and a driving mechanism 12, the driving mechanism 12 is mounted on the housing 11, wherein the cutter head 20 includes a cutter mechanism 21 and a mesh cover 22, the cutter mechanism 21 is mounted on the housing 11 and is drivably connected to the driving mechanism 12, and the mesh cover 22 is rotatably mounted on the housing 11 of the hand-held part 10 and covers the cutter mechanism 21. When the driving mechanism 12 drives the blade mechanism 21 to rotate, a shearing force is generated between the blade mechanism 21 and the net cover 22 to shear the beard coming in through the mesh of the net cover 22, and when the user pushes the electric shaver integrally, the net cover 22 is allowed to rotate relative to the housing 11 of the hand-held portion 10 to cause rolling of the net cover 22 relative to the facial skin, so that sliding friction is prevented from being generated between the net cover 22 and the facial skin of the user to improve the comfort of the user when shaving with the electric shaver. In this process, although both the blade mechanism 21 and the net cover 22 are capable of generating rotation with respect to the housing 11, the blade mechanism 21 is driven by the driving mechanism 12, the net cover 22 is driven by the facial skin due to friction with the facial skin when the user pushes the electric shaver integrally, and thus the rotation speed of the blade mechanism 21 is much greater than that of the net cover 22, so that a shearing force can be generated between the blade mechanism 21 and the net cover 22 to shear the beard entered through the mesh of the net cover 22.

More specifically, referring to fig. 3 to 5, the housing 11 includes a first housing 111 and a second housing 112, and has a fitting space 113 and a fitting hole 114 communicating with the fitting space 113, wherein the first housing 111 and the second housing 112 are mounted to each other to form the fitting space 113 and the fitting hole 114 between the first housing 111 and the second housing 112.

It should be noted that the mounting manner of the first housing 111 and the second housing 112 is not limited in the electric shaver of the present utility model, for example, in some embodiments, the first housing 111 and the second housing 112 may be locked by screws, and in other embodiments, the first housing 111 and the second housing 112 may be locked by a snap structure.

The driving mechanism 12 includes a driving motor 121, and the driving motor 121 is mounted in the assembly space 113 of the housing 11. In order to prevent the driving motor 121 from shaking in the assembly space 113 of the housing 11, the first housing 111 and the second housing 112 are each provided with at least one clamping arm 1111, the clamping arms 1111 protruding toward the assembly space 113, wherein the clamping arms 1111 of the first housing 111 and the clamping arms 1111 of the second housing 112 clamp the driving motor 121 on opposite sides of the driving motor 121, respectively, to allow the driving motor 121 to be reliably mounted in the assembly space 113 of the housing 11.

The blade mechanism 21 includes a blade holder 211 and a blade 212 provided to the blade holder 211, the driven end 2111 of the blade holder 211 is rotatably mounted to the fitting hole 114 of the housing 11, and the driven end 2111 of the blade holder 211 is drivably connected to the drive motor 121, so that the drive motor 121 can drive the blade mechanism 21 to rotate.

It should be noted that the manner in which the driven end 2111 of the cartridge 211 is rotatably mounted to the fitting hole 114 of the housing 11 is not limited in the electric shaver of the present utility model. For example, the driven end 2111 of the blade holder 211 may be rotatably mounted to the mounting aperture 114 of the housing 11 by a bearing such that the blade 21 can be driven for rotation relative to the housing 11 when the drive motor 121 is powered.

The fitting end 221 of the net cover 22 is rotatably installed to the fitting hole 114 of the housing 11, and the blade 212 of the blade mechanism 21 tends to be close to the inner wall of the net cover 22, so that when the driving motor 121 drives the blade holder 211 and the blade 212 of the blade mechanism 21 to rotate, the blade 212 and the net cover 22 can generate a shearing force to cut the beard entered through the mesh of the net cover 22. The net cover 22 is passive, and the net cover 22 and the blade mechanism 21 are independent from each other, i.e., when the user pushes the electric shaver as a whole, the net cover 22 can roll against the skin of the face, which is advantageous in simplifying the structure of the electric shaver and improving the reliability of the electric shaver.

It should be noted that the manner in which the fitting end 221 of the net cover 22 is rotatably mounted to the fitting hole 114 of the housing 11 is not limited in the electric shaver of the present utility model. For example, the fitting hole 221 of the net cover 22 may be rotatably mounted to the fitting hole 114 of the housing 11 through a bearing, so that the net cover 22 may roll against the facial skin when the user pushes the electric shaver as a whole, to improve the user's comfort when shaving using the electric shaver.

With continued reference to fig. 1-5, the first housing 111 includes a first housing body 1112 and a first extension arm 1113 integrally extending outwardly from a corner of the first housing body 1112, the second housing 112 includes a second housing body 1122 and a second extension arm 1123 integrally extending outwardly from a corner of the second housing body 1122, wherein the fitting space 113 of the housing 11 is formed between the first housing body 1112 of the first housing 111 and the second housing body 1122 of the second housing 112, the fitting hole 114 of the housing 11 is formed between the first extension arm 1113 of the first housing 111 and the second extension arm 1123 of the second housing 112, such that after the cutter head 20 is mounted to the fitting hole 114 of the housing 11, there is a gap between the first screen 1112 and an outer wall of the screen 22 of the first housing 111 and a gap between the second screen 1122 and 22 of the second housing 112, allowing rotation of the screen 22.

With continued reference to fig. 3 and 4, the drive mechanism 12 includes a drive shaft 122, the drive shaft 122 having a shaft bottom end 1221 and a shaft top end 1222 corresponding to the shaft bottom end 1221, wherein the shaft bottom end 1221 of the drive shaft 122 is drivably connected to the output shaft of the drive motor 121, and the shaft top end 1222 of the drive shaft 122 is drivably connected to the driven end 2111 of the tool holder 211 such that when the drive motor 121 outputs power in a manner that the output shaft of the drive motor 121 rotates, the power can be transmitted to the tool holder 211 via the drive shaft 122 to drive the tool holder 211 to rotate relative to the housing 11 and the net 22. It will be appreciated that while the user pushes the electric shaver integrally, although the net cover 22 is rotatable with respect to the facial skin of the user, the rotational speed of the blade mechanism 21 is far higher than that of the net cover 22 by the driving of the driving motor 121, so that a sufficient shearing force can be generated between the blades 212 of the blade mechanism 21 and the net cover 22 for shearing the beard entered through the mesh of the net cover 22.

Preferably, in order to prevent the swing of the driving shaft 122 and secure the driving power capability of the driving shaft 122, the driving shaft 122 may be mounted to the first casing 111 and/or the second casing 112 of the housing 11 through a set of bearings.

Preferably, the output shaft of the drive motor 121 may be provided with a worm, and correspondingly, the shaft bottom end 1221 of the drive shaft 122 is provided with shaft teeth, the shaft teeth of the shaft bottom end 1221 of the drive shaft 122 and the worm of the drive motor 121 are engaged with each other to allow the shaft bottom end 1221 of the drive shaft 122 to be drivably connected to the output shaft of the drive motor 121, and the output shaft of the drive motor 121 and the drive shaft 122 form a right angle transmission structure. The shaft top 1222 of the drive shaft 122 is provided with shaft teeth and, correspondingly, the driven end 2111 of the tool holder 211 is provided with driven teeth, the shaft teeth of the shaft top 1222 of the drive shaft 122 and the driven teeth of the driven end 2111 of the tool holder 211 intermesh to allow the shaft top 1222 of the drive shaft 122 to be drivably connected to the driven end 2111 of the tool holder 211, and the drive shaft 122 and the tool holder 211 form another right angle drive. With such a structure as described above, the transmission shaft 122 can efficiently transmit the power supplied from the drive motor 121 to the blade holder 211 to allow the blade holder 211 and the blade 212 to be rotatable at a high speed.

Preferably, referring to fig. 3 to 6, the blades 212 of the blade mechanism 21 of the head 20 extend in a spiral shape from the driven end 2111 of the cutter holder 211 to the other end, so that when the blades 212 are rotated by the cutter holder 211, a shearing force can be generated between the blades 212 and the net cover 22 to cut the beard entering through the mesh of the net cover 22, on the one hand, and on the other hand, the blades 212 can push the beard toward the end of the net cover 22 away from the fitting end 221 to avoid the beard from affecting the shaving effect of the electric shaver.

In other words, by providing the blades 212 of the blade mechanism 21 of the head section 20 in a spiral shape, it is possible to prevent Hu Zhadui from being accumulated between the blades 212 and the net cover 22 during shaving by the electric shaver, and to prevent shaving from affecting the shaving effect of the electric shaver.

With continued reference to fig. 4 and 5, the hand-held portion 10 of the electric shaver further comprises a circuit board 13, a control switch 14 and a power supply element 15, wherein the circuit board 13 is integrated with the MCU module to have the corresponding function, the control switch 14 is attached to the circuit board 13, the driving motor 121 of the driving mechanism 12 and the power supply element 15 are respectively connected to the circuit board 13, and the circuit board 13 and the power supply element 15 are held in the fitting space 113 of the housing 11.

The circuit board 13 can control the state in which the power supply element 15 supplies power to the drive motor 121 through the control switch 14. For example, the user may operate the control switch 14 to cause the circuit board 13 to allow the power supply element 15 to supply power to the driving motor 121, at which time the power supplied by the driving motor 121 can be transmitted to the blade holder 211 of the blade mechanism 21 via the transmission shaft 122 to cause the blade mechanism 21 to rotate relative to the mesh enclosure 22. Accordingly, the user can operate the control switch 14 to cause the circuit board 13 to prevent the power supply element 15 from supplying power to the driving motor 121, and at this time, the driving motor 121 is no longer powered.

Preferably, the circuit board 13 is fixedly mounted to the first housing 111 of the housing 11, for example, the circuit board 13 may be screwed to the first housing 111 by screws to allow the circuit board 13 to be reliably held in the fitting space 113 of the housing 11.

Preferably, the first housing 111 has a switch penetration hole 1114 communicating the assembly space 113 with the outside, wherein the control switch 14 extends from the assembly space 113 to the outside through the switch penetration hole 1114 of the first housing 111 to allow a user to operate the control switch 14 at the outside of the case 11.

Preferably, the power supply element 15 is a rechargeable battery, and electrical energy can be supplied to the power supply element 15 via a power adapter. Alternatively, in other embodiments of the electric shaver of the present utility model, the power supply element 15 may be a dry cell, which is replaceable.

(a) The blade mechanism 21 of the cutter head 20 is driven to rotate relative to the mesh enclosure 22 by the driving mechanism 12 of the hand-held part 10 so as to generate shearing force between the blades 212 of the blade mechanism 21 and the mesh enclosure 20 to shear the beard entering through the meshes of the mesh enclosure 22; and

(b) The net cover 22 is allowed to roll against the facial skin of the user when the user pushes the electric shaver as a whole, so that sliding friction between the net cover 22 and the facial skin of the user is avoided to improve the user's comfort when shaving with the electric shaver.

Further, the step (a) further includes:

(a.1) supplying power to the drive motor 121 of the drive mechanism 12 to allow the output shaft of the drive motor 121 to rotate to provide power; and

(a.2) allowing the power supplied from the driving motor 121 to be transmitted to the cutter holder 211 of the cutter mechanism 21 via the transmission shaft 122 so that the cutter holder 211 rotates the cutter 212 provided to the cutter holder 211 in synchronization, thereby generating a shearing force between the cutter 212 and the net cover 20 to shear the beard entered through the mesh of the net cover 22.

Preferably, the step (a) further comprises: (a.3) pushing the shaving debris toward one end of the head portion 20 to avoid Hu Zhadui from being trapped between the blades 212 and the cap 22 and affecting the shaving result. Preferably, in the step (a.3), during shaving, the shaving debris is pushed toward one end of the head portion 20 by the blade 212. Specifically, referring to fig. 3 to 6, the blade 212 of the blade mechanism 21 of the head 20 extends in a spiral shape from the driven end 2111 of the cutter holder 211 to the other end, so that when the blade 212 is driven to rotate by the cutter holder 211, a shearing force can be generated between the blade 212 and the net cover 22 to shear the beard entering through the mesh of the net cover 22, and on the other hand, the blade 212 can push the beard toward the end of the net cover 22 far from the mounting end 221 to avoid the beard from affecting the shaving effect of the electric shaver.

An electric shaver according to another preferred embodiment of the present utility model will be disclosed and described in the following description with reference to fig. 8 to 14 of the drawings, wherein the electric shaver comprises a hand-held portion 10A and a cutter portion 20A mounted to the hand-held portion 10A.

Specifically, the hand-held portion 10A includes a housing 11A and a driving mechanism 12A mounted to the housing 11A, the head portion 20A includes a blade mechanism 21A and a mesh 22A, the blade mechanism 21A is mounted to the housing 11A and is drivably connected to the driving mechanism 12A, and the mesh 22A is rotatably mounted to the housing 11A and covers the blade mechanism 21A. When the driving mechanism 12A drives the blade mechanism 21A to rotate, a shearing force is generated between the blade mechanism 21A and the net cover 22A to shear the beard coming in through the mesh of the net cover 22A, and when the user pushes the electric shaver as a whole, the net cover 22A is allowed to rotate relative to the housing 11A of the hand-held portion 10A to cause rolling of the net cover 22A relative to the facial skin, so that sliding friction between the net cover 22A and the facial skin of the user is avoided to improve comfort when the user uses the electric shaver. In this process, although both the blade mechanism 21A and the net cover 22A are capable of generating rotation relative to the housing 11A, the blade mechanism 21A is driven by the driving mechanism 12A, the net cover 22A is driven by the facial skin due to friction with the facial skin when the user pushes the electric shaver integrally, and thus the rotation speed of the blade mechanism 21A is much greater than that of the net cover 22A, so that a shearing force can be generated between the blade mechanism 21A and the net cover 22A to shear the beard entered through the mesh of the net cover 22A.
