The cutter head assembly 1300 is a separate component independent of the body 1000, and can be detached and washed separately. The cutter head can be a cutter head, a brush head, a massage head, a care head, etc.

[0108] The body 1000 is substantially vertical to the horizontal plane and is cylindrical, and has a body cavity 110 for accommodating the battery inside, and a display screen 1020 is provided on the outside.

In the vertical direction, the upper surface of the first arc segment 1112 is higher than the upper surface of the second arc segment 1114. The upper surface of the central portion 1122 is coplanar with the upper surface of the second arc segment 1114.

[0109] The support member 1200 is disposed at the top of the fuselage 1000 and is roughly L-shaped and includes a support arm 1210 located on one side of the fuselage, and a support ring 1220 located at the bottom of the support arm 1210 and integrally connected, wherein the support ring 1220 can rotate relative to the fuselage 1000 around a rotation axis.

The receiving space formed between the support arm 1210 and the support ring 1220 is used to receive the cutter head assembly 1300 and allow the cutter head assembly 1300 to rotate. The upper end of the support ring 1220 has a central cavity 1240 that allows the central portion 1122 to enter, an annular portion 1242 located at the bottom of the central cavity 1240, and a screw 1244 that limits the annular portion 1242 and connects it to the body 1000 and allows the annular portion 1242 to rotate relative to the body 1000. The lower surface of the screw 1244 maintains a vertical gap with the annular portion 1242. The lower end of the support ring 1220 is provided with a limiting cavity 1222, a supporting base 1226 isolating the free cavity 1240 from the limiting cavity 1222, a limiting protrusion 1224 disposed on the supporting base 1226 and protruding downward, a limiting protrusion 1228 adjacent to and located outside the limiting protrusion 1224, and a limiting center hole 1229 located at the center of the limiting protrusion 1224, which allows the central portion 1122 to partially pass through. There is a height difference between the bottom end surface of the limiting protrusion 1224 and the bottom end surface of the limiting protrusion 1228, and the limiting protrusion 1224 rotates in the stop groove 1254, while the limiting protrusion 1228 follows the trajectory of the second arc segment 1114 and is limited by the height difference of the steps at the two ends of the first arc segment 111. The sealing ring 1032 is disposed adjacent to the elastic member 1250.

[0110] The cutter head assembly 1300 includes a housing 1320, a plurality of cutter head nets 1330 disposed on the housing 1320, and a cutter head net cover 1340 that fixes the cutter head nets 1330 on the housing 1320. The housing 1320 has a power chamber for accommodating a power unit. The cutter head assembly 1300 is connected to the support member 1200 via a connecting shaft 1322, and the cutter head assembly 1300 rotates in a first direction around the connecting shaft 1322. One end of the connecting shaft 1322 is disposed on the housing 1320, and the other end is detachably connected to the shaft hole 1212, or can be connected by magnetic attraction, which is more convenient for disassembly and cleaning of the cutter head assembly 1300. The stop center hole 1278, the connecting shaft 1322, and the shaft hole 1212 are coaxial, and the stop portion 1270 is fixedly connected to the connecting shaft 1322 to ensure that the stop portion 1270 and the connecting shaft 1322 rotate as one.

Fig.21 shown.

[0111] Therefore, the present invention separates the power unit from the fuselage, and the original space in the fuselage can be used to increase the capacity of the battery, extend the battery life of the product, and reduce the complexity of the internal structure of the fuselage.

[0112] The present invention greatly increases the floating freedom and angle of the blade head of the electric shaver, solving the problem that the blade head of traditional electric shavers has a small floating and swinging angle, and because the motor technology is relatively primitive, noise and vibration will be generated during shaving, and consumers cannot be provided with a shaving experience that perfectly matches their facial contours, while achieving the unity of compactness and portability with powerful performance.

[0113] The present invention uses multiple axes (first axis, second axis) with different angles to form multiple free rotation activity spaces, which can be freely moved at any time. It perfectly replaces the traditional tools that need to rely on the freedom of human joints to use the product. The angle of movement is greater than the angle of movement of human joints, which can maximize the user's experience, better reach the hair trimming position, and capture hair with a larger free movement angle. The present invention can be more widely used in shavers, hair dryers, shavers, lint trimmers, beauty devices, hydrating devices, hair stylers, curling straighteners, electric toothbrushes, manual shavers, epilators, etc.

[0114] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
