[0028] See also Figures 1 to 3 In the specific embodiment shown, the utility model discloses a shaver structure, including: a main body 10, a cutter head assembly 20 and a transmission assembly 30, the transmission assembly 30 including a primary transmission part 31, a secondary transmission part 32 and a tertiary transmission part 33, the primary transmission part 31 is transmission-connected to the main body 10, the secondary transmission part 32 is transmission-connected to the primary transmission part 31, the tertiary transmission part 33 is transmission-connected to the secondary transmission part 32, and the cutter head assembly 20 is transmission-connected to the tertiary transmission part 33.

[0029] Specifically, the multi-stage transmission design allows the shaver to achieve a wider range of movement of the cutter head with smaller wrist movements. This means that when using the shaver, users can easily reach and shave hair in different parts without having to swing their wrists drastically or lift and turn the shaver frequently. In addition, since the range of wrist and arm movements is reduced, users will feel more relaxed and comfortable when using the shaver. This design helps reduce fatigue caused by long shaving periods, thereby improving the overall shaving experience. In addition, the multi-stage transmission system also means that the shaver can adapt to different shaving needs more flexibly; for example, by adjusting the transmission ratio, the speed or power of the cutter head can be changed to adapt to hair of different hardness and density.

[0030] In one embodiment, the host 10 includes a shell 11, a motor 12, a mounting bracket 13 and a motor gear 14. The mounting bracket 13 is installed inside the shell 11, the motor 12 is connected to the mounting bracket 13, the motor gear 14 is transmission-connected to the output shaft of the motor 12, and the first-stage transmission part 31 is transmission-connected to the motor gear 14.

[0031] Specifically, the shell 11 serves as the external protective structure of the main unit 10, and the shell 11 provides a safe and stable accommodation space for the internal components; the mounting bracket 13 is fixed inside the shell 11, and its main function is to support and fix the motor 12 to ensure that the motor 12 will not be displaced or damaged due to vibration or external force during operation; the motor gear 14 is connected to the output shaft of the motor 12, and its function is to transmit the rotational power of the motor 12 to the next-level component (i.e., the first-level transmission part 31) at a specific transmission ratio. The design of this transmission ratio can be adjusted according to the working requirements of the shaver to achieve the best shaving effect and efficiency; the first-level transmission part 31 is connected to the motor gear 14, receives power from the motor gear 14, and further transmits it to subsequent transmission parts (such as the second-level transmission part 32, the third-level transmission part 33, etc.), until it finally drives the cutter head assembly 20 to perform shaving operations. This continuous transmission system ensures that the shaver can work smoothly and efficiently.

[0032] In one embodiment, the first-stage transmission part 31 includes a first-stage rotating shaft 311 and a first-stage transmission bevel gear 312. One end of the first-stage rotating shaft 311 is connected to the mounting bracket 13, and the other end is connected to the first-stage transmission bevel gear 312. The first-stage transmission bevel gear 312 is engaged with the motor gear 14 for transmission.

[0033] Specifically, the primary rotating shaft 311, a key component of the transmission system, is connected to the mounting bracket 13 at one end and to the primary transmission bevel gear 312 at the other end. This design ensures smooth transmission of power from the motor gear 14 to the primary transmission bevel gear 312. The meshing transmission of the primary transmission bevel gear 312 with the motor gear 14 is an important link in the power transmission process. The design of the bevel gear makes the transmission process smoother, reduces vibration and noise, and improves the efficiency and load-bearing capacity of the transmission. In addition, the primary transmission unit 31 transmits the rotational power generated by the motor 12 to the subsequent transmission unit through the primary rotating shaft 311 and the primary transmission bevel gear 312. The meshing transmission method of the bevel gears ensures the smoothness and accuracy of power transmission and reduces power loss. The transmission efficiency of the bevel gear is generally higher than that of the spur gear because it can better distribute the force on the gear teeth, reducing wear and damage caused by uneven force. At the same time, the bevel gear has a stronger load-bearing capacity and can adapt to larger loads and more severe working environments. In addition, the design of the primary transmission part 31 makes the entire transmission system more compact and reduces the occupied space; at the same time, the meshing mode of the helical gears also helps to improve the stability of the transmission system, making the shaver more reliable during use.

[0034] In one embodiment, the secondary transmission part 32 includes a secondary rotating shaft 321, an internal gear 322 and an external gear 323. The internal gear 322 and the external gear 323 are distributed up and down and are connected to the secondary rotating shaft 321 to form an integrated structure. The internal gear 322 is meshed with the primary transmission bevel gear 312 for transmission, and the external gear 323 is connected to the tertiary transmission part 33 for transmission.

[0035] Specifically, the secondary rotating shaft 321, as one of the key components of the transmission system, connects the internal gear 322 and the external gear 323, forming an integral structure. This design ensures smooth transmission of power from the primary transmission part 31 to the secondary transmission part 32, and then to the tertiary transmission part 33. The internal gear 322 and the external gear 323 are arranged vertically and connected to the secondary rotating shaft 321 to form an integral structure. The internal gear 322 meshes with the primary transmission bevel gear 312 to receive power from the primary transmission part 31, while the external gear 323 is connected to the tertiary transmission part 33 to further transmit power to the next stage. This also makes the entire transmission system more compact and reduces space occupation. In other words, by adopting the design of the secondary rotating shaft 321, the internal gear 322 and the external gear 323, the smoothness, accuracy and efficiency of power transmission are achieved, while the stability and adaptability of the transmission system are improved. These advantages make the shaver more stable, reliable and comfortable during use, meeting the shaving needs of different users.

[0036] In one embodiment, the three-stage transmission part 33 includes a mounting plate 331 and at least two three-stage transmission gears 332. The three-stage transmission gear 332 is connected to the mounting plate 331 through a three-stage rotating shaft 333. The three-stage transmission gear 332 is transmission-connected to the external gear 323. The three-stage rotating shaft 333 is also transmission-connected to the cutter head assembly 20.

[0037] Specifically, the mounting plate 331 serves as the support structure for the three-stage transmission unit 33. The mounting plate 331 secures and supports at least two three-stage transmission gears 332, ensuring their stable operation. The at least two three-stage transmission gears 332 are connected to the mounting plate 331 via a three-stage rotating shaft 333, forming part of the transmission. These three-stage transmission gears 332 engage with the external gear 323 for transmission, receiving and transmitting power from the two-stage transmission unit 32. The three-stage rotating shaft 333 not only connects the three-stage transmission gears 332 but also is connected to the cutter head assembly 20, ultimately transmitting power to the cutter head and driving it for shaving. Furthermore, the design of the three-stage transmission unit 33 makes the entire transmission system more compact, reduces space usage, and improves the portability of the shaver. The support of the mounting plate 331 and the connection to the three-stage rotating shaft 333 ensure that the three-stage transmission gears 332 operate stably, reducing damage caused by vibration or external forces.

[0038] Preferably, there are three three-stage transmission gears 332, meaning the shaver has three blade heads. Compared to a single or dual blade head, three blade heads can cover a larger shaving area, thereby removing more hair in a single shaving session. A multi-blade design generally results in a higher shaving speed because each blade head can work independently and together to complete the task, thereby shortening shaving time. Furthermore, three blade heads can better conform to facial contours, especially difficult-to-shave areas like the chin and neck, reducing the pulling and discomfort during shaving. The increased number of blade heads also means a larger contact area with the skin, dispersing the pressure during shaving and making the shaving process gentler.

[0039] In one embodiment, the cutter head assembly 20 includes a cutter head mounting frame 21, a cutter head component 22 and a cutter head rotating wheel 23. The cutter head component 22 is installed on the cutter head mounting frame 21. One end of the cutter head rotating wheel 23 is transmission connected to the third-stage rotating shaft 333, and the other end is transmission connected to the cutter head component 22.

[0040] Specifically, the cutter head mounting frame 21 serves as the basic support structure of the cutter head assembly 20. The cutter head mounting frame 21 ensures the stable installation of the cutter head 22 and the cutter head rotor 23. It provides the necessary strength and rigidity to prevent deformation or damage due to excessive force during shaving. The cutter head 22 is a key component for the actual shaving operation. It is usually composed of a sharp blade and a protective net. The cutter head 22 is mounted on the cutter head mounting frame 21. Through precise assembly and positioning, it ensures stability and accuracy during shaving. The cutter head rotor 23 plays a key role in power transmission and conversion in the shaver. One end of the cutter head rotor is connected to the third-level shaft 333 to receive power from the transmission system, and the other end is connected to the cutter head 22 to convert power into rotation of the cutter head 22, thereby achieving the shaving function. In addition, the precise design and manufacture of the cutter wheel 23 ensures minimal power loss during transmission from the tertiary shaft 333 to the cutter element 22, which helps to improve the efficiency and performance of the shaver while reducing energy consumption and noise.

[0041] In one embodiment, a support and limiting plate 24 is further provided between the cutter head wheel 23 and the three-stage transmission gear 332 , and the three-stage rotating shaft 333 passes through the support and limiting plate 24 and is transmission-connected to the cutter head wheel 23 .

[0042] Specifically, the support and limit plate 24 serves as a connecting bridge between the tertiary transmission gear 332 and the cutter head rotor 23, enhancing the structural stability of the entire transmission system. This ensures that the tertiary transmission gear 332 will not fall off or shift due to excessive force or vibration during high-speed rotation, thereby ensuring the proper operation and safety of the shaver. Furthermore, the tertiary transmission gear 332 is a crucial component of the shaver's transmission system, and its stable operation is crucial for ensuring a good shaving effect. The design of the support and limit plate 24 effectively prevents transmission failure of the tertiary transmission gear 332 due to uneven force or excessive vibration during the transmission process, ensuring smooth power transmission from the tertiary transmission gear 332 to the cutter head rotor 23, and avoiding poor shaving results or damage to the shaver due to transmission failure.

[0043] In one embodiment, the razor structure further includes an upper shell 40, which is connected to the housing 11, the secondary rotating shaft 321 and the mounting plate 331 are connected to the upper shell 40, and the primary transmission bevel gear 312 extends into the upper shell 40 and is transmission-connected to the internal gear 322.

[0044] Specifically, the upper shell 40, as an important component of the razor structure, is connected to the housing 11 and together constitutes the main frame of the razor. The upper shell 40 provides a stable support for the internal transmission components (such as the secondary rotating shaft 321, the mounting plate 331, etc.), ensuring the stability and reliability of the razor during operation. In addition, by connecting the secondary rotating shaft 321 and the mounting plate 331 to the upper shell 40, the overall structural strength of the razor is enhanced, which helps to resist the vibration and impact force generated during the shaving process and extend the service life of the razor. In addition, the primary transmission bevel gear 312 extends into the upper shell 40 and is connected to the internal gear 322. This design optimizes the layout of the transmission system, making power transmission smoother and more efficient, and reducing energy loss and transmission noise.

[0045] Specifically, the cutter head mounting frame 21, support and limiting plate 24, and mounting plate 331 are arranged from top to bottom and secured by screws, forming a stable layered structure. This layered design helps disperse the vibration and impact forces generated during shaving, thereby enhancing the stability of the entire shaver structure. Furthermore, the screws tightly connect these components together, ensuring their firmness and stability. The screw connection not only provides sufficient tightening force but also prevents loosening or falling off due to vibration during use.

[0046] In one embodiment, the host 10 further includes a battery component 15, a control board and a main bracket 16. The main bracket 16 is installed inside the shell 11. The control board and the battery component 15 are connected to the main bracket 16. The battery component 15 and the motor 12 are electrically connected to the control board.

[0047] Specifically, the battery pack 15 serves as the power source for the shaver, providing the required electrical energy to the motor 12, ensuring that the shaver can function normally without the need for an external power source, thereby improving ease of use. The control panel is electrically connected not only to the battery pack 15 but also to the motor 12. This connection method enables the control panel to monitor the charge level of the battery pack 15 and the operating status of the motor 12 in real time, thereby achieving precise control of the shaver's operating status. In addition, the mounting bracket 13 is connected to the main bracket 16 via screws. The main bracket 16 serves as the main support structure inside the shaver, providing stable support for components such as the battery pack 15, the control panel, and the mounting bracket 13, ensuring the stability and reliability of these components during the shaving process.

[0048] In one embodiment, a switch element 17 is further provided on the outside of the housing 11 , and the switch element 17 is electrically connected to the control board.

[0049] Specifically, the most basic and important function of switch 17 is to control the power supply. When the user presses switch 17, the circuit is closed, and battery 15 supplies power to components such as the control panel and motor 12, and the shaver begins to operate. When the user turns off switch 17, the circuit is disconnected, and the shaver stops operating. This design ensures that the user can easily control the shaver's on and off states, improving ease of use and safety. Furthermore, in some advanced shavers, switch 17 is more than just a simple power switch; it may also function as a function switch. For example, by using different button combinations or long or short presses, the user can switch between different shaving modes, vibration intensities, or cleaning modes. This design allows the shaver to meet the needs and preferences of different users, improving the product's practicality and competitiveness.

[0050] Among them, other structures of the host 10 adopt existing public technologies and will not be elaborated on here.

[0051] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
