Description

Technical Field

[0001] This invention relates to the field of toiletries technology, and in particular to a manually powered, purely mechanical rotary shaving mechanism. Background Technology

[0002] Razors are a common tool in people's daily lives. Traditional electric razors rely on electricity, requiring frequent charging or battery replacements. Once the battery is low, they cannot be used properly. In some special situations, such as while traveling or engaging in outdoor activities, the lack of suitable charging equipment can be inconvenient for users. Furthermore, the motors and circuits of electric razors are relatively complex, resulting in higher production costs and greater difficulty in repair. While manual razors do not require electricity, most use a simple blade-cutting method, leading to lower shaving efficiency and difficulty in achieving efficient speed adjustment. For users with thick beards, the shaving effect is often unsatisfactory. In addition, during the use of a manual razor, the hand applies direct force to the blades, which can easily cause skin abrasions due to uneven force, resulting in a poor user experience.

One side of the connecting rod 91 is movably connected to the upper side of the front cover 8, and the other side of the connecting rod 91 is movably connected to the left side of the handle 94 via the first rotating shaft 92. The right side of the handle 94 is movably connected to the upper side of the power input ratchet module 3 via the second rotating shaft 95. The center of the return torsion spring 96 is located outside the first rotating shaft 92, and the outer sides of the return torsion spring 96 are respectively connected to the other side of the connecting rod 91 and the left side of the handle 94. The pulley 93 is movably connected to the lower left side of the handle 94, and the lower side of the pulley 93 is connected to the outside of the outer shell 1.

[0043] The invention is used as follows: It features a reasonable and simple structure, low production cost, and convenient installation. In use, first hold the outer casing 1 and press the handle 94, causing the connecting piece 311 to move the slide rod 312 and rack 314 downwards. Additionally, the left side of the handle 94 is movably connected to the connecting rod 91 via a rotating shaft 92. During rotation, the return force provided by the return torsion spring 96 can be clearly felt. Releasing the handle 94 will cause the connecting piece 311 to move the slide rod 312 and rack 314 upwards. The pulley 93 and connecting rod 91 are designed to compensate for the displacement caused when the handle 94 is pressed. When the rack 314 moves downward, it drives the transmission gear 315 to rotate in one direction. The transmission gear 315 then drives the mainspring turntable 39 to rotate through the ratchet external tooth 318 and the ratchet locking tongue 310. When the handle 94 is released, the rack 314 moves upward, driving the transmission gear 315 to rotate. At this time, since the ratchet external tooth 318 and the ratchet locking tongue 310 can only transmit power in one direction, they will not drive the mainspring turntable. When the mainspring drive disc 39 rotates, it drives the mainspring drive shaft 37 to rotate. The rotation of the mainspring drive shaft 37 tightens the mainspring spring 32, storing elastic potential energy. The ratchet latch 36 engages with the ratchet internal tooth 317 to prevent the mainspring drive disc 39 from reversing. The elastic potential energy stored in the mainspring spring 32 drives the mainspring barrel 31 to rotate. The ratchet latch 316 on the left side of the mainspring barrel 31 engages with the ratchet internal tooth 42 on the right side of the one-way output ratchet disc 41 to transmit power to the one-way power. Output module 4 then drives the three planetary gears 52 to rotate via the planetary ring gear 43 on the left side of the unidirectional output ratchet disc 41. Simultaneously, planetary gears 52 mesh with the sun gear 53 on the right side of the movable disc 54, causing the movable disc 54 to rotate. The planetary ring gear 522 on the left side of the movable disc 54 drives the three planetary gears 55 to rotate, and so on. Through multi-stage planetary gear transmission, acceleration and speed change are achieved. With only two presses per second, the speed can reach 4860 RPM. The planetary gear 517 drives the sun gear 62 to rotate, which in turn causes the flywheel 61 to rotate. The flywheel 61 uses its inertia to balance the rotation speed. The rotating needle 63 on the left side of the flywheel 61 is connected to the rotating head 73 of the blade module 7. The rotating needle 63 drives the rotating head 73 to rotate, and the rotating head 73 drives the blade 74 to rotate at high speed in the blade net 75 to shave the beard. During the shaving process, the contact angle and force between the blade head and the face are adjusted in a timely manner according to the density and distribution of the beard to achieve the best shaving effect.

[0044] The control method of this invention is either manual start-up or control through existing automation technology. The wiring diagram of the power element and the supply of power are common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail here.
