[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution for an electric shaver structure with an adjustable blade angle.

[0027] like Figure 1 - Figure 6 As shown, the device includes a shaver body 1, with a shaver head assembly 2 positioned above the shaver body 1. The shaver head assembly 2 includes a connecting blade disc 21 and a protective blade cover 22 nested together. An adjusting rod 309 is fixedly connected to the connecting blade disc 21. The protective blade cover 22 protects other components in the shaver head assembly 2. The adjusting rod 309 supports the shaver head assembly 2. When the adjusting rod 309 swings, it can cause the shaver head assembly 2 to change its angle, thereby adjusting the shaving angle of the shaver head assembly 2 to meet various user needs and improve the applicability of the device.

[0028] Inside the protective blade cover 22 is a set of razor modules 23. The inner top wall of the connecting blade disc 21 is rotatably connected to a main gear 24 and a set of driven gears 25. Inside the adjusting rod 309 is a micro motor that drives the main gear 24 to rotate. The surface of the razor body 1 has a button to control the start of the micro motor. The user can control the start of the motor by pressing the button. When the motor starts, it drives the main gear 24 to rotate in the connecting blade disc 21. The rotation of the main gear 24 drives the driven gears 25 to rotate, providing power for shaving.

[0029] A protective plate 26 is fixedly connected inside the connecting disc 21. Each driven gear 25 meshes with the main gear 24, and the top of each driven gear 25 is engaged with the razor module 23. The razor module 23 includes an internal razor blade and a fixed blade structure. The end of the driven gear 25 is engaged with the fixed structure. The rotation of the driven gear 25 can drive the blade in the razor module 23 to rotate, thereby shaving the user's beard. The protective plate 26 provides a certain protection effect, preventing the shaving stubble from falling between the main gear 24 and the driven gear 25 and affecting the use of the device. The internal structure and installation method of the razor head assembly 2 are technologies well known to those skilled in the art, so they will not be described in detail.

[0030] The shaver body 1 has an adjustment mechanism 3 inside. The adjustment mechanism 3 includes a fixed base 301 and an adjustment top plate 302. The adjustment top plate 302 rotates inside the shaver body 1. The fixed base 301 is fixed inside the shaver body 1 by bolts. An adjustment connecting rod 309 is fixedly connected to the top surface of the adjustment top plate 302. Arc-shaped support plates 304 are fixedly connected to both ends of the adjustment top plate 302. The fixed base 301 supports the swinging of the adjustment top plate 302. The two ends of the fixed base 301 slide against the two arc-shaped support plates 304. When the adjusting top plate 302 swings under the action of the adjusting worm 303 and the limiting worm wheel 305, the fixed base 301 can provide stable support and limiting effect for the swing of the adjusting top plate 302 through the arc-shaped support plate 304. The swing of the adjusting top plate 302 can drive the adjusting connecting rod 309 to swing. The top surface of the shaver body 1 is provided with a sliding groove that matches the adjusting connecting rod 309. When the adjusting connecting rod 309 swings in the sliding groove, it can drive the blade head assembly 2 to change position, thereby adjusting the tilt angle of the blade head assembly 2 for convenient use.

[0031] An adjusting worm gear 303 is rotatably connected to the bottom of the adjusting top plate 302. A drive motor 308 is fixedly mounted on the outer surface of the adjusting top plate 302. The adjusting worm gear 303 is fixedly connected to the output shaft of the drive motor 308. A limiting worm wheel 305 is fixedly connected to the middle of the fixed base 301. The adjusting worm gear 303 meshes with the limiting worm wheel 305. A button for controlling the forward and reverse rotation of the drive motor 308 is mounted on the outer surface of the shaver body 1. The drive motor 308 and the button are electrically connected via wires. The button controls the start and stop of the drive motor 308 by pressing it. The drive motor 308 is powered by the battery pack inside the shaver body 1. When the drive motor 308 is started, it can drive the adjusting worm gear 303 to rotate. The rotation of the adjusting worm gear 303 will drive the adjusting top plate 302 to move under the limiting action of the limiting worm wheel 305. The adjusting top plate 302 will change from moving to swinging under the limitation of the arc-shaped sliding bar 306 and the limiting slide rail 307, thereby driving the adjusting connecting rod 309 to swing, providing power for the adjustment of the blade angle of the device. The drive motor 308 is prior art, and will not be described in detail in this application.

[0032] Each arc-shaped support plate 304 has an arc-shaped sliding strip 306 fixedly connected to its bottom surface. Both ends of the fixed base 301 are provided with limiting slide rails 307. The two arc-shaped sliding strips 306 slide in the two limiting slide rails 307 respectively. Both the arc-shaped sliding strips 306 and the limiting slide rails 307 are T-shaped designs, which can effectively improve the limiting effect of the limiting slide rails 307 on the arc-shaped sliding strips 306, so that the arc-shaped sliding strips 306 can slide at a certain angle inside the limiting slide rails 307, thereby improving the support effect of the fixed base 301 on the adjusting top plate 302.

[0033] Working principle: When the user wants to adjust the angle of the cutter head of this device, first select the corresponding button according to the adjustment direction, and then press the corresponding button. The button controls the drive motor 308 to start. The start of the drive motor 308 can drive the adjusting worm 303 to rotate. The rotation of the adjusting worm 303 will move under the limiting action of the limiting worm wheel 305. The adjusting top plate 302 can only swing along a certain angle under the limiting action of the arc sliding bar 306 and the limiting slide 307. The movement of the adjusting worm 303 will drive the adjusting top plate 302 to swing, thereby adjusting the support angle of the adjusting connecting rod 309, and then adjusting the overall tilt angle of the cutter head assembly 2. After adjusting to the appropriate angle, the user can release the button.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
