Description

TECHNICAL FIELD

[0001] The utility model relates to the field of household appliances, in particular to a gear mechanism, knife net driving mechanism, double output driving mechanism and shaver. BACKGROUND

[0002] In the prior art, the knife net of the shaver is static or can only rotate in one direction, which causes the situation that the beard is not easy to be rolled into the knife net, and it is difficult to smoothly put the beard into the cutting range, and the situation that the beard is pulled instead of being cut off is easy to appear, and the skin after shaving may have more stubble, which is not smooth enough and also reduces the comfort of shaving, making the user experience bad. SUMMARY

[0003] Therefore, it is necessary to provide a gear mechanism, a knife net driving mechanism, a double output driving mechanism and a shaver aiming at the problem that the knife net of the shaver is static or can only rotate in one direction.

[0004] A gear mechanism, the gear mechanism comprising: a power input mechanism for driving with a power mechanism; a speed reduction mechanism, the input side of the speed reduction mechanism being drivingly connected with the power input mechanism; a first direction transmission mechanism, the output side of the speed reduction mechanism being drivingly connected with the first direction transmission mechanism; a second direction transmission mechanism, the second direction transmission mechanism being drivingly connected with the first direction transmission mechanism, and the rotation direction of the second direction transmission mechanism being opposite to that of the first direction transmission mechanism; and a first transmission output mechanism, the first transmission output mechanism being drivingly connectable with part of the first direction transmission mechanism and part of the second direction transmission mechanism respectively.

[0005] The above discloses a gear mechanism, by using the power mechanism to drive the power input mechanism, provides the original power for the power input mechanism, so as to start the whole power system. The reduction mechanism is in transmission connection with the power input mechanism, which can effectively reduce the rotating speed of the power, so that the rotating speed is reduced to a suitable degree, thereby providing a more suitable power speed for the subsequent working parts to meet the actual working requirements, and at the same time, the reduction of the rotating speed improves the torque, so that the power can more powerfully drive the cutter screen and the blade, and ensure the smooth progress of the shaving process. The first direction transmission mechanism is in transmission connection with the reduction mechanism, and the second direction transmission mechanism is in transmission connection with the first direction transmission mechanism, so as to realize the control of the rotating direction of the first transmission output mechanism. By controlling different rotating directions, the shaver provided with the gear mechanism can control the rotating direction of the cutter screen to realize different angle shaving through the gear mechanism. When the cutter screen of the shaver rotates forward, it can normally cut the beard, and the reverse rotation is helpful to clean the sundries such as beard stubble stuck in the holes of the cutter screen. In the shaving process, the beard cut off may be left in the holes of the cutter screen, and with the increase of the use times, these residual beard will gradually accumulate and block the cutter screen. The reverse rotation of the cutter screen can loosen these blockages, so as to maintain the good air permeability and cutting performance of the cutter screen. At the same time, the forward and reverse rotation function of the cutter screen can make the shaver better fit the growth direction of the beard. When the forward rotation cannot well cut some reverse growth beard, the reverse rotation can process these beard from another angle, which can lift and cut the lying beard or hair, so that the shaving is more thorough, and also can play a certain massage effect. Furthermore, the forward and reverse rotation function can make the wear of the blade and the cutter screen more uniform, which can distribute the wear in more areas, avoid local excessive wear, and thereby prolong the service life of the shaver as a whole.

[0006] In one of the embodiments, the first direction transmission mechanism comprises a first transmission gear and a first direction transmission gear, the first transmission gear is in transmission connection with the output side of the speed reduction mechanism, the first direction transmission gear is arranged on the first transmission gear, the second direction transmission mechanism comprises a second transmission gear and a second direction transmission gear, the second transmission gear is in mesh with the first transmission gear, the second direction transmission gear is arranged on the second transmission gear, the first direction transmission gear can be in mesh with the first transmission output mechanism and drive the first transmission output mechanism to rotate in the first direction when the first transmission gear rotates, the second direction transmission gear can be in mesh with the first transmission output mechanism and drive the first transmission output mechanism to rotate in the second direction when the second transmission gear rotates, the first direction is opposite to the second direction, the time when the second direction transmission gear is in mesh with the first transmission output mechanism and the time when the first direction transmission gear is in mesh with the first transmission output mechanism are staggered. By transmission connection of the first transmission gear and the speed reduction mechanism, the high rotation speed output by the motor is converted into a lower rotation speed and a larger torque suitable for the operation of the razor net. At the same time, through the transmission connection of the first transmission gear and the speed reduction mechanism, the first transmission gear can receive power from the speed reduction mechanism to provide a power source for the subsequent working components of the razor. The first direction transmission gear is arranged on the first transmission gear, and the rotation of the first transmission gear drives the first direction transmission gear to rotate at the same time. The second transmission gear is in mesh with the first transmission gear, and power is transmitted to the second transmission gear, which also drives the second direction transmission gear arranged on the second transmission gear to rotate, so that the first direction transmission gear and the second direction transmission gear alternately drive the first transmission output mechanism, so that the rotation direction of the first transmission output mechanism can be alternately changed to realize the purpose of forward and reverse rotation of the razor net, and provide power support for the forward and reverse rotation. The forward and reverse rotation of the razor net can contact the beard in different directions, thereby expanding the effective area of shaving. Compared with the single direction rotating razor net, the forward and reverse rotation can more comprehensively capture the beard growing in different directions, can automatically adjust the rotation direction according to the growth direction of the beard, better fit the beard, reduce the omission, improve the coverage range of shaving, thereby realize a cleaner shaving effect, and can better adapt to the growth direction of the beard, can reduce the number of repeated shaving in the same area. This not only saves time, but also reduces the irritation and friction to the skin and reduces the discomfort caused in the shaving process.

[0007] In one of the embodiments, the first direction transmission gear includes a first direction base and a plurality of first direction teeth, the first direction base is arranged on the first transmission gear, and the first direction teeth are arranged along the circumference of the side wall of the first direction base. By arranging the first direction base on the first transmission gear, the power of the first transmission gear is smoothly transmitted to the first direction base, and then transmitted to the first direction teeth through the first direction base, and the first transmission output mechanism is driven to rotate in the forward direction by the first direction teeth, thereby realizing the forward rotation of the cutter net. The cooperative work among the first direction base, the first direction teeth and the first transmission output mechanism is an embodiment of optimizing the internal mechanical structure of the shaver. They cooperate with each other to form an organic whole, so that the power can be transmitted in the predetermined direction and manner. This cooperative work not only improves the efficiency of the forward rotation of the cutter net, but also reduces the mutual interference and wear between the components.

[0008] In one of the embodiments, the second direction transmission gear includes a second direction base and a plurality of second direction teeth, the second direction base is arranged on the second transmission gear, and the second direction teeth are arranged along the circumference of the side wall of the second direction base. By arranging the second direction base on the second transmission gear, the power of the second transmission gear is smoothly transmitted to the second direction base, and then transmitted to the second direction teeth through the second direction base, and the first transmission output mechanism is driven to rotate in the reverse direction by the second direction teeth, thereby realizing the reverse rotation of the cutter net. The cooperative work among the second direction base, the second direction teeth and the first transmission output mechanism is an embodiment of optimizing the internal mechanical structure of the shaver. They cooperate with each other to form an organic whole, so that the power can be transmitted in the predetermined direction and manner. This cooperative work not only improves the efficiency of the reverse rotation of the cutter net, but also reduces the mutual interference and wear between the components.

[0009] In one of the embodiments, the speed reduction mechanism is a gear speed reduction mechanism. By arranging the speed reduction mechanism as a gear speed reduction mechanism, high-precision speed control can be realized, and the rotation speed can be accurately reduced according to the design requirements. Meanwhile, the meshing between the gears is a relatively stable transmission mode. Under appropriate lubrication and maintenance conditions, the gear speed reduction mechanism can provide stable power transmission, reduce fluctuations in the power transmission process, and improve the working stability and reliability of the equipment.

[0010] In one of the embodiments, the speed reduction mechanism comprises a first gear, a second gear, a third gear and a fourth gear, the first gear is in driving connection with the power input mechanism, the second gear is in driving connection with the first gear, the third gear is in driving connection with the second gear, the fourth gear is in driving connection with the third gear, and the fourth gear is in driving connection with the first direction transmission mechanism. By dividing the speed reduction mechanism into a first gear, a second gear, a third gear and a fourth gear, the purpose of multi-stage speed reduction is achieved. The number of teeth, modulus and other parameters of each gear can be used as variables to adjust the power output. By changing the transmission ratio between the gears, the output speed and torque can be adjusted in small steps. Compared with single-stage gear speed reduction mechanism, the multi-stage gear arrangement provides a wider range of power adjustment and higher adjustment accuracy.

[0011] In one of the embodiments, the first transmission output mechanism comprises a third transmission gear, a first transmission shaft, a first floating support, a first transmission floating block and a fourth transmission gear, the third transmission gear is in driving connection with the first direction transmission gear and the second direction transmission gear respectively, the first transmission shaft is arranged on the third transmission gear, the first transmission floating support is arranged on the first transmission shaft, the first transmission floating block is arranged on the first transmission shaft and / or the first transmission floating support, and the fourth transmission gear is arranged on the first transmission floating block. By driving the third transmission gear with the first direction transmission gear or the second direction transmission gear, the purpose of forward and reverse rotation of the third transmission gear is achieved. When the first direction transmission gear meshes with the third transmission gear, the third transmission gear rotates forward, and when the second direction transmission gear meshes with the third transmission gear, the third transmission gear rotates reversely, which can better adapt to different shaving conditions. This forward and reverse rotation function provides users with a more comfortable and efficient shaving experience. In the early stage of shaving, forward rotation of the cutter mesh can quickly remove most of the beard; in the later stage of shaving or for some stubborn beard, reverse rotation can more accurately capture and remove the remaining beard. At the same time, the reverse rotation of the cutter mesh also plays an important role in the cleaning process, which can prevent the accumulation of beard stubble in the cutter mesh, maintain the cleanliness of the cutter mesh, thereby prolonging the service life of the cutter mesh and ensuring good shaving effect each time. Arranging the first transmission shaft on the third transmission gear, the first transmission floating block on the first transmission shaft and the first transmission floating support, and the fourth transmission gear on the first transmission floating block ensures the continuity of power in the entire transmission system, avoids interruption or sudden change of power transmission, and at the same time, this compact structure can realize more complex power transmission and adjustment function without increasing the size of the equipment, improving the space utilization of the equipment. The first transmission floating block can absorb external forces such as collision during transmission or shaving process, improve the structural strength of the shaver and prolong its service life.

[0012] The second aspect of the present application discloses a cutter net driving mechanism, which comprises the gear mechanism mentioned above and a cutter net assembly.

[0013] The second aspect of the above application discloses a cutter net driving mechanism. By engaging the cutter net assembly with the output end of the first transmission output mechanism, a direct power transmission link from the power source to the cutter net assembly is established. This direct power supply mode ensures that the cutter net assembly can obtain stable and effective power, so that it can perform rotational motion and thus play a role in the shaving process. At the same time, this engagement mode can accurately drive the cutter net assembly to perform a shaving action. The power characteristics output by the first transmission output mechanism are transmitted to the cutter net assembly through engagement, enabling the cutter net to rotate at an appropriate speed and force. At the same time, transmitting power through engagement can also enhance the stability of the cutter net assembly motion. The mechanical structure of the engagement can effectively resist external interference and internal power fluctuations during power transmission.

[0014] In one embodiment, the rotation angle of the cutter net assembly is 1-359°. By setting the rotation angle of the cutter net assembly to 1-359°, comprehensive coverage of the shaving area can be achieved. During shaving, the cutter net needs to constantly change angles such as 10°, 50°, 100°, etc. to fit the different contours of the face, such as the distribution of beard on the chin, mouth corner, etc. This wide range of rotation angles can ensure that the cutter net assembly can cover the beard growth area through appropriate angle rotation whether it is on a flat cheek or a complex chin, mouth corner, etc. so that the cutter net can closely fit the curvature of the chin, effectively capturing and cutting the beard, and avoiding missing.

[0015] In one embodiment, the rotation frequency of the cutter net assembly is 10-1000 times per minute. By setting the rotation frequency of the cutter net assembly to 10-1000 times per minute, the efficiency of shaving can be effectively improved. Higher rotation frequency means that the cutter net can cover a larger shaving area in unit time. At the same time, the density and texture of different people's beard are different, lower rotation frequency is suitable for the case of sparse or soft beard, the cutter net assembly can gently contact the skin and accurately cut the beard, avoiding excessive irritation to the skin. For the case of dense and hard beard, higher rotation frequency can provide sufficient power and cutting times, so that the cutter net assembly can smoothly penetrate the beard layer and effectively cut the beard, ensuring the effect of shaving.

[0016] In one of the embodiments, the number of the cutter net assemblies is multiple. By setting the number of the cutter net assemblies as multiple, the coverage area during shaving can be significantly increased. During shaving, each cutter net assembly can work independently while covering different areas of the face, and compared with a single cutter net assembly, a larger face area can be covered in a shorter time, thereby effectively improving the shaving efficiency. The cooperation of the multiple cutter net assemblies with the multi-angle rotation can cut the beard growing in the forward direction or the reverse direction from multiple angles, thereby improving the user experience.

[0017] In one of the embodiments, the cutter net assembly comprises a cutter net driving tooth, a cutter net driven sleeve, a spring and a cutter net. The cutter net driving tooth is in meshing and transmission connection with the first transmission output mechanism. The cutter net driven sleeve is arranged on the cutter net driving tooth and can float relative to the cutter net driving tooth. The spring is clamped between the cutter net driving tooth and the cutter net driven sleeve. The cutter net is arranged on the cutter net driven sleeve. By meshing and transmission connection of the cutter net driving tooth with the first transmission output mechanism, a stable and reliable power transmission path is established. Then, the cutter net driven sleeve is arranged on the cutter net driving tooth, the spring is clamped between the cutter net driving tooth and the cutter net driven sleeve, and the cutter net is arranged on the cutter net driven sleeve, thereby forming a complete power transmission link from the power source to the cutter net. The spring clamped between the cutter net driving tooth and the cutter net driven sleeve plays an important role in buffering and shock absorption. During shaving, the cutter net assembly will generate vibration and impact, and the spring can absorb these vibrations and impacts to avoid the cutter net directly subjected to strong force, thereby protecting the cutter net and related components from damage. Meanwhile, the presence of the spring enables the cutter net to have the ability of self-adaptive shaving. When the cutter net contacts different contours and beard densities of the face, the spring can automatically adjust the relative position between the cutter net driven sleeve and the cutter net driving tooth according to the actual situation to ensure the shaving effect.

[0018] The third aspect of the present application discloses a double-output driving mechanism, which comprises: a power mechanism; the cutter net driving mechanism; the power input mechanism comprises a first gear, a connecting rod and a second gear, the first gear and the second gear are arranged on the connecting rod, the first gear and the second gear are located at both ends of the connecting rod, the first gear is in meshing with the power mechanism and the speed reduction mechanism respectively; a moving cutter assembly, part of the moving cutter assembly is arranged in the cutter net assembly and can rotate in the cutter net assembly; the second gear is in meshing with the power input end of the moving cutter assembly.

[0019] The third aspect discloses a double-output driving mechanism. The first gear is engaged with the power mechanism and the speed reduction mechanism, so that the first gear can directly receive the power generated by the power mechanism, and the power can be transmitted to the connecting rod and the second gear, and then transmitted to the moving cutter assembly by the second gear to drive the moving cutter assembly. Meanwhile, the first gear is engaged with the speed reduction mechanism, which transmits the power obtained from the power mechanism to the speed reduction mechanism to establish a continuous power transmission link from the power source to the speed reduction mechanism, ensuring that the power can be effectively transmitted inside the device. The moving cutter of the moving cutter assembly is arranged in the cutter net assembly, and the moving cutter and the cutter net assembly are rotated simultaneously to shave, the cutter net assembly guides the beard into the shaving area, and the rotation of the cutter net assembly makes the beard better adhere to the cutter net, and the rotation of the moving cutter directly cuts the beard, greatly improving the efficiency and effect of shaving, and achieving fine shaving.

[0020] In one embodiment, the moving cutter assembly includes a moving cutter driving gear and a plurality of moving cutter driven assemblies. The moving cutter driving gear is engaged with and drivingly connected to the second gear. The plurality of moving cutter driven assemblies are arranged along the circumference of the moving cutter driving gear and engaged with the moving cutter driving gear. By engaging and drivingly connecting the moving cutter driving gear with the second gear, a power transmission channel from the power source to the moving cutter assembly is established, so that the moving cutter driving gear can obtain sufficient power to drive the moving cutter to perform a shaving action. By engaging and drivingly connecting the plurality of moving cutter driven assemblies along the circumference of the moving cutter driving gear, the power can be evenly distributed from the moving cutter driving gear to each moving cutter driven assembly, ensuring that each moving cutter driven assembly can obtain stable power and avoiding the situation that some moving cutters work excessively while others work insufficiently due to uneven power, thereby ensuring the consistency of the shaving action in the entire shaving area. Meanwhile, the plurality of moving cutter driven assemblies are arranged along the circumference of the moving cutter driving gear, which can better fit different contours, and they can flexibly adjust the position and angle according to the shape of each part of the face to ensure that the beard in each corner can be effectively handled, improving the thoroughness of shaving.

[0021] In one of the embodiments, the driven cutter assembly comprises a driven gear, a driven shaft, a cutter floating block, a cutter floating bracket and a cutter, the driven gear is engaged with and drivingly connected to the cutter driving gear, the driven shaft is arranged on the driven gear, the cutter floating bracket is arranged on the driven shaft, the cutter floating block is arranged on the driven shaft and / or the cutter floating bracket, and the cutter is arranged on the cutter floating block. By engaging and drivingly connecting the driven gear with the cutter driving gear, power is provided to the driven gear. Arranging the driven shaft on the driven gear, the cutter floating block on the driven shaft and the cutter floating bracket, and the cutter on the cutter floating block, enables the power to be effectively transmitted to the cutter through the driven shaft, ensuring that the cutter can obtain sufficient power to perform shaving action. At the same time, the cutter floating block arranged on the driven shaft plays an important role in buffering and damping during the power shaving process, and the cutter floating block can absorb the impact and vibration during shaving to make the shaving more stable. The cutter floating block can buffer these external disturbances through its own elasticity and floating characteristics, reducing the impact on the cutter, thereby prolonging the service life of the cutter.

By reasonably arranging these components in this area, the space can be effectively utilized, and the excessive space occupied by the dispersion of various components in different positions can be effectively avoided, so that the overall volume of the shaver is smaller, and the shaver is more convenient to carry and use. At the same time, the handle housing assembly provides structural support for these components, ensuring that each mechanism can work stably and normally. Part of the gear mechanism is arranged on the head housing assembly, the cutter net assembly is arranged on the head housing assembly, and part of the cutter assembly is arranged on the head housing assembly, so that the components in the head housing assembly work cooperatively, which can ensure that the rotation of the cutter net assembly and the cutter assembly is more synchronous and smooth, and at the same time, the head housing assembly can absorb part of the impact force, reducing the risk of damage to the cutter net assembly and the cutter assembly, and prolonging the service life of the components.

[0047] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other manners different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0049] Some embodiments of the present application are described below with reference to the accompanying drawings, which illustrate the gear mechanism, the cutter net driving mechanism, the double output driving mechanism and the shaver.

[0050] Embodiment 1

[0051] As shown in Figures 1 to 4 the embodiment, a gear mechanism is disclosed, comprising: a power input mechanism 1, the power input mechanism 1 is used for driving with a power mechanism 7; a speed reduction mechanism 2, the input side of the speed reduction mechanism 2 is drivingly connected with the power input mechanism 1; a first direction transmission mechanism 3, the first direction transmission mechanism 3 is drivingly connected with the output side of the speed reduction mechanism 2; a second direction transmission mechanism 4, the second direction transmission mechanism 4 is drivingly connected with the first direction transmission mechanism 3, and the rotation direction of the second direction transmission mechanism 4 is opposite to that of the first direction transmission mechanism 3; a first transmission output mechanism 5, the first transmission output mechanism 5 can be drivingly connected with part of the first direction transmission mechanism 3 and the second direction transmission mechanism 4 respectively.

[0052] The application discloses a gear mechanism, which is driven by a power input mechanism 1 through a power mechanism 7 to provide original power for the power input mechanism 1, so as to start the whole power system. The power speed is effectively reduced by driving connection of a speed reduction mechanism 2 and the power input mechanism 1, so that the rotating speed is reduced to a proper degree, thereby providing a more suitable power speed for subsequent working components to meet actual working requirements, and the torque is improved while the rotating speed is reduced, so that the power can more powerfully drive the cutter screen and the cutter blade, and the smoothness of the shaving process is ensured. The first direction transmission mechanism 3 is drivingly connected with the speed reduction mechanism 2, and the second direction transmission mechanism 4 is drivingly connected with the first direction transmission mechanism 3, so that the rotating direction of the first transmission output mechanism 5 is controlled, and the shaving razor provided with the gear mechanism can realize different angle shaving by controlling the rotating direction of the cutter screen through the gear mechanism. When the cutter screen of the shaving razor rotates forward, it can normally cut the beard, and the reverse rotation is helpful to clean the sundries such as beard stubble stuck in the holes of the cutter screen. In the shaving process, the beard cut off may be left in the holes of the cutter screen, and with the increase of the use times, the left beard is gradually accumulated to block the cutter screen. The reverse rotation of the cutter screen can loosen the blockage, so that the good air permeability and cutting performance of the cutter screen are maintained. Meanwhile, the forward and reverse rotation function of the cutter screen can make the shaving razor better fit the growth direction of the beard, and when the forward rotation cannot well cut some beard growing in the reverse direction, the reverse rotation can process the beard from another angle, can lift and cut the lying beard or hair, can make the shaving more thorough, and can also play a certain massage role. Furthermore, the forward and reverse rotation function can make the wear of the cutter blade and the cutter screen more uniform, can make the wear distributed in more areas, avoids local excessive wear, and thereby prolongs the service life of the whole shaving razor.

[0053] As Figure 2 , Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment is further limited in that: the first direction transmission mechanism 3 includes a first transmission gear 31 and a first direction transmission gear 32, the first transmission gear 31 is in transmission connection with the output side of the speed reduction mechanism 2, the first direction transmission gear 32 is arranged on the first transmission gear 31, the second direction transmission mechanism 4 includes a second transmission gear 41 and a second direction transmission gear 42, the second transmission gear 41 is in mesh with the first transmission gear 31, the second direction transmission gear 42 is arranged on the second transmission gear 41, the first direction transmission gear 32 can mesh with and drive the first transmission output mechanism 5 to rotate in the first direction when the first transmission gear 31 rotates, the second direction transmission gear 42 can mesh with and drive the first transmission output mechanism 5 to rotate in the second direction when the second transmission gear 41 rotates, the first direction is opposite to the second direction, and the time when the second direction transmission gear 42 meshes with the first transmission output mechanism 5 and the time when the first direction transmission gear 32 meshes with the first transmission output mechanism 5 are staggered in turn. By connecting the first transmission gear 31 in transmission with the speed reduction mechanism 2, the high rotation speed output by the motor is converted into a lower rotation speed and a larger torque suitable for the operation of the razor head. At the same time, through the transmission connection of the first transmission gear 31 with the speed reduction mechanism 2, the first transmission gear 31 can receive power from the speed reduction mechanism to provide a power source for the subsequent working components of the razor. By arranging the first direction transmission gear 32 on the first transmission gear 31, the rotation of the first transmission gear 31 can drive the first direction transmission gear 32 to rotate. By meshing the second transmission gear 41 with the first transmission gear 31, power is transmitted to the second transmission gear 41, which in turn drives the second direction transmission gear 42 arranged on the second transmission gear 41 to rotate, so that the first direction transmission gear 32 and the second direction transmission gear 42 alternately drive the first transmission output mechanism 5, so that the rotation direction of the first transmission output mechanism 5 can be alternately changed to realize the purpose of forward and reverse rotation of the razor head, and provide power support for the forward and reverse rotation. The forward and reverse rotation of the razor head can contact the beard in different directions, thereby expanding the effective area of shaving. Compared with the single-direction rotating razor head, the forward and reverse rotation can more comprehensively capture the beard growing in different directions, and can automatically adjust the rotation direction according to the growth direction of the beard, better fit the beard, reduce the missed area, and improve the coverage of shaving, thereby realizing a cleaner shaving effect. At the same time, it can better adapt to the growth direction of the beard, and can reduce the number of times of repeated shaving in the same area. This not only saves time, but also reduces the irritation and friction to the skin, and reduces the discomfort caused during shaving.

[0054] As Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first direction transmission gear 32 includes a first direction base 321 and first direction teeth 322. The first direction base 321 is disposed on the first transmission gear 31, and the number of first direction teeth 322 is multiple, with the multiple first direction teeth 322 arranged circumferentially along a portion of the sidewall of the first direction base 321. By disposing the first direction base 321 on the first transmission gear 31, the power of the first transmission gear 31 is smoothly transmitted to the first direction base 321, and then the power is transmitted to the first direction teeth 322 through the first direction base 321. The first direction teeth 322 then drive the first transmission output mechanism 5 to rotate in the positive direction, realizing the forward rotation of the shaver foil. The cooperative work between the first direction base 321, the first direction teeth 322, and the first transmission output mechanism 5 is a manifestation of optimizing the internal mechanical structure of the shaver. They cooperate with each other to form an organic whole, enabling power to be transmitted in a predetermined direction and manner. This cooperative work not only improves the efficiency of the forward rotation of the shaver foil but also reduces mutual interference and wear between components.

[0055] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: the second direction transmission gear 42 includes a second direction base 421 and a second direction tooth 422. The second direction base 421 is disposed on the second transmission gear 41, and the number of second direction teeth 422 is multiple, with the multiple second direction teeth 422 arranged circumferentially along a portion of the sidewall of the second direction base 421. By disposing the second direction base 421 on the second transmission gear 41, the power of the second transmission gear 41 is smoothly transmitted to the second direction base 421, and then the power is transmitted to the second direction teeth 422 through the second direction base 421. The second direction teeth 422 drive the first transmission output mechanism 5 to rotate in the opposite direction, thereby achieving the reversal of the razor foil. The coordinated work between the second direction base 421, the second direction teeth 422, and the first transmission output mechanism 5 is a manifestation of optimizing the internal mechanical structure of the razor. They cooperate with each other to form an organic whole, enabling power to be transmitted in a predetermined direction and manner. This coordinated work not only improves the efficiency of razor foil reversal but also reduces mutual interference and wear between components.

[0056] like Figure 2 and Figure 3As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the speed reduction mechanism 2 is a gear speed reduction mechanism. By setting the speed reduction mechanism 2 as a gear speed reduction mechanism, high-precision speed control can be achieved, and the rotational speed can be reduced more accurately according to design requirements. At the same time, the meshing between the wheels is a relatively stable transmission mode. Under appropriate lubrication and maintenance conditions, the gear speed reduction mechanism can provide stable power transmission and reduce fluctuations during power transmission, thereby improving the working stability and reliability of the equipment.

At the same time, the meshing between the wheels is a relatively stable transmission mode. Under appropriate lubrication and maintenance conditions, the gear speed reduction mechanism can provide stable power transmission and reduce fluctuations during power transmission, thereby improving the working stability and reliability of the equipment. Figure 2 Figure 3 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the speed reduction mechanism 2 is a gear speed reduction mechanism. By setting the speed reduction mechanism 2 as a gear speed reduction mechanism, high-precision speed control can be achieved, and the rotational speed can be reduced more accurately according to design requirements. At the same time, the meshing between the wheels is a relatively stable transmission mode.

[0058] As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the speed reduction mechanism 2 is a gear speed reduction mechanism. By setting the speed reduction mechanism 2 as a gear speed reduction mechanism, high-precision speed control can be achieved, and the rotational speed can be reduced more accurately according to design requirements. At the same time, the meshing between the wheels is a relatively stable transmission mode. Under appropriate lubrication and maintenance conditions, the gear speed reduction mechanism can provide stable power transmission and reduce fluctuations during power transmission, thereby improving the working stability and reliability of the equipment. Figure 3 Figure 4 ​​As shown, in addition to the features of the above embodiments, this embodiment is further limited in that: the first transmission output mechanism 5 comprises a third transmission gear 51, a first transmission shaft 52, a first transmission floating support 53, a first transmission floating block 54 and a fourth transmission gear 55, the third transmission gear 51 is capable of being in transmission connection with the first direction transmission gear 32 and the second direction transmission gear 42 respectively, the first transmission shaft 52 is arranged on the third transmission gear 51, the first transmission floating support 53 is arranged on the first transmission shaft 52, the first transmission floating block 54 is arranged on the first transmission shaft 52 and / or the first transmission floating support 53, and the fourth transmission gear 55 is arranged on the first transmission floating block 54. By connecting the third transmission gear 51 with the first direction transmission gear 32 or the second direction transmission gear 42, the purpose of forward and reverse rotation of the third transmission gear 51 is achieved. When the first direction transmission gear 32 meshes with the third transmission gear 51, the third transmission gear 51 rotates forward, and when the second direction transmission gear 42 meshes with the third transmission gear 51, the third transmission gear 51 rotates reversely, which can better adapt to different shaving conditions. This forward and reverse rotation function provides users with a more comfortable and efficient shaving experience. In the early stage of shaving, the forward rotation of the cutter net can quickly remove most of the beard; in the later stage of shaving or for some more stubborn beard, the reverse rotation can more accurately capture and remove the remaining beard. At the same time, the reverse rotation of the cutter net also plays an important role in the cleaning process, which can prevent the accumulation of beard in the cutter net, maintain the cleanliness of the cutter net, thereby prolonging the service life of the cutter net, and ensuring good shaving effect each time. By arranging the first transmission shaft 52 on the third transmission gear 51, the first transmission floating block 54 on the first transmission shaft 52 and the first transmission floating support 53, and the fourth transmission gear 55 on the first transmission floating block 54, the layer-by-layer transmission mode ensures the continuity of power in the entire transmission system, avoids interruption or mutation of power transmission, and at the same time, this compact structure can realize more complex power transmission and adjustment functions without increasing the size of the equipment, thereby improving the space utilization of the equipment. The first transmission floating block 54 can absorb external forces such as collision during the transmission process or the shaving process, improve the structural strength of the shaver, and prolong its service life.

[0059] Embodiment 2

[0060] As Figures 1 to 7 shown, this embodiment discloses a cutter net driving mechanism, which comprises: the above-mentioned gear mechanism, a cutter net assembly 6, and the cutter net assembly 6 is in mesh with the output end of the first transmission output mechanism 5.

[0061] The second aspect of the present application discloses a cutter net driving mechanism. By engaging the cutter net assembly 6 with the output end of the first transmission output mechanism 5, a direct power transmission link from the power source to the cutter net assembly 6 is established. This direct power supply method ensures that the cutter net assembly 6 can obtain stable and effective power, enabling it to perform rotational motion and thus play a role in the shaving process. At the same time, this engagement method can accurately drive the cutter net assembly 6 to perform a shaving action. The power characteristics output by the first transmission output mechanism 5 are transmitted to the cutter net assembly 6 through engagement, allowing the cutter net to rotate at an appropriate speed and force. At the same time, transmitting power through engagement can also enhance the stability of the movement of the cutter net assembly 6. The mechanical structure of the engagement can effectively resist external interference and internal power fluctuations during power transmission.

[0062] As shown in Figure 2 , in addition to the features of the above embodiments, this embodiment further limits the rotation angle of the cutter net assembly 6 to 1-359°. By setting the rotation angle range of the cutter net assembly 6 to 1-359°, comprehensive coverage of the shaving area can be achieved. During shaving, the cutter net needs to constantly change angles such as 10°, 50°, 100°, etc. to fit the different contours of the face, such as the mustache distribution on the chin and mouth corners. This wide range of rotation angles can ensure that the cutter net assembly 6 can cover the mustache growth area through appropriate angle rotation whether it is on a flat cheek or a complex chin and mouth corner, allowing the cutter net to closely fit the curvature of the chin, effectively capturing and cutting the mustache, and avoiding missed areas.

[0063] As shown in Figure 2 , in addition to the features of the above embodiments, this embodiment further limits the rotation frequency of the cutter net assembly 6 to 10-1000 times per minute. By setting the rotation frequency of the cutter net assembly 6 to 10-1000 times per minute, the efficiency of shaving can be effectively improved. Higher rotation frequency means that the cutter net can cover a larger shaving area in unit time. At the same time, different people have different mustache densities and textures, and lower rotation frequency is suitable for cases where the mustache is sparse or soft in texture. The cutter net assembly 6 can gently contact the skin and accurately cut the mustache, avoiding excessive irritation to the skin. For cases where the mustache is dense and hard in texture, higher rotation frequency can provide sufficient power and cutting times, allowing the cutter net assembly 6 to smoothly penetrate the mustache layer and effectively cut the mustache, ensuring the effectiveness of shaving.

[0064] As shown in Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that the number of foil components 6 is multiple. By setting the number of foil components 6 to multiple, the coverage area during shaving can be significantly increased. During shaving, each foil component can work independently, covering different areas of the face simultaneously. Compared to a single foil component 6, it can cover a larger facial area in a shorter time, thereby effectively improving shaving efficiency. Multiple foil components 6, combined with multi-angle rotation, can cut forward-growing or reverse-growing beard hairs from multiple angles, improving the user experience.

[0065] like Figure 5 , Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: the blade mesh assembly 6 includes a blade mesh drive tooth 61, a blade mesh driven sleeve 62, a spring 63, and a blade mesh 64. The blade mesh drive tooth 61 meshes with and is connected to the first transmission output mechanism 5. The blade mesh driven sleeve 62 is disposed on the blade mesh drive tooth 61 and can float relative to the blade mesh drive tooth 61. The spring 63 is sandwiched between the blade mesh drive tooth 61 and the blade mesh driven sleeve 62. The blade mesh 64 is disposed on the blade mesh driven sleeve 62. By meshing and connecting the blade mesh drive tooth 61 with the first transmission output mechanism 5, a stable and reliable power transmission path is established. Furthermore, by disposing the blade mesh driven sleeve 62 on the blade mesh drive tooth 61, the spring 63 being sandwiched between the blade mesh drive tooth 61 and the blade mesh driven sleeve 62, and the blade mesh 64 being disposed on the blade mesh driven sleeve 62, a complete power transmission link from the power source to the blade mesh 64 is formed. Spring 63, sandwiched between the foil drive teeth 61 and the foil driven sleeve 62, plays a crucial role in buffering and shock absorption. During shaving, the foil assembly 6 generates vibrations and impacts. Spring 63 absorbs these vibrations and impacts, preventing the foil 64 from being directly subjected to strong forces, thus protecting the foil 64 and its related components from damage. Simultaneously, the presence of spring 63 enables the foil 64 to adapt to different facial contours and beard densities. When the foil 64 comes into contact with different facial contours and beard densities, spring 63 automatically adjusts the relative position between the foil driven sleeve 62 and the foil drive teeth 61 according to the actual situation, ensuring a good shaving effect.

[0066] Example 3

[0067] like Figures 2 to 8As shown, the embodiment discloses a double-output driving mechanism, comprising: a power mechanism 7; the above-mentioned cutter net driving mechanism; the power input mechanism 1 comprises a first gear 11, a connecting rod 12 and a second gear 13, the first gear 11 and the second gear 13 are arranged on the connecting rod 12, the first gear 11 and the second gear 13 are located at both ends of the connecting rod 12, the first gear 11 is engaged with the power mechanism 7 and the speed reduction mechanism 2 respectively; a moving cutter assembly 8, part of the moving cutter assembly 8 is arranged in the cutter net assembly 6 and can rotate in the cutter net assembly 6; the second gear 13 is engaged with the power input end of the moving cutter assembly 8.

[0068] The third aspect of the application discloses a double-output driving mechanism, by engaging the first gear 11 with the power mechanism 7 and the speed reduction mechanism 2 respectively, so that the first gear 11 can directly receive the power generated by the power mechanism 7, and can transmit the power to the connecting rod 12 and the second gear 13, and then transmit the power to the moving cutter assembly 8 by the second gear 13, to realize the driving of the moving cutter assembly 8, and at the same time, the first gear 11 is engaged with the speed reduction mechanism 2, which transmits the power obtained from the power mechanism 7 to the speed reduction mechanism 2, establishing a continuous power transmission link from the power source to the speed reduction mechanism, ensuring that the power can be effectively transmitted inside the device. Then the moving cutter of the moving cutter assembly 8 is arranged in the cutter net assembly 6, and the moving cutter and the cutter net assembly 6 are rotated at the same time to shave, the cutter net assembly 6 plays a role in guiding the beard into the shaving area, and the rotation can make the beard better adhere to the cutter net, and the rotation of the moving cutter directly cuts the beard, greatly improving the efficiency and effect of shaving, and realizing fine shaving.

[0069] As Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the moving blade assembly 8 includes a moving blade drive gear 81 and moving blade driven components 82. The moving blade drive gear 81 meshes with and is connected to the second gear 13. There are multiple moving blade driven components 82, which are arranged circumferentially around the moving blade drive gear 81 and mesh with it. By meshing and connecting the moving blade drive gear 81 with the second gear 13, a power transmission channel from the power source to the moving blade assembly 8 is established, enabling the moving blade drive gear 81 to obtain sufficient power to drive the moving blades to perform shaving actions. By meshing and connecting multiple moving blade driven components 82 circumferentially around the moving blade drive gear 81, power can be evenly distributed from the moving blade drive gear 81 to each moving blade driven component 82, ensuring that each moving blade driven component 82 receives stable power. This avoids situations where some moving blades overwork while others underwork due to uneven power, thereby ensuring the consistency of the shaving action throughout the entire shaving area. Meanwhile, multiple driven blade components 82 are arranged circumferentially along the driven blade gear 81, which can better fit these different contours. They can flexibly adjust their position and angle according to the shape of each part of the face, ensuring that the beard in every corner can be effectively treated and improving the thoroughness of shaving.

[0070] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the driven tool assembly 82 includes a driven gear 821, a driven shaft 822, a moving tool floating bracket 823, a moving tool floating block 824, and a moving tool 825. The driven gear 821 meshes with and is connected to the moving tool drive gear 81. The driven shaft 822 is disposed on the driven gear 821, the moving tool floating bracket 823 is disposed on the driven shaft 822, the moving tool floating block 824 is disposed on the driven shaft 822 and / or the moving tool floating bracket 823, and the moving tool 825 is disposed on the moving tool floating block 824. By meshing with and connecting the driven gear 821 to the moving tool drive gear 81, power is provided to the driven gear 821. The driven shaft 822 is mounted on the driven gear 821, the moving blade floating bracket 823 is mounted on the driven shaft 822, the moving blade floating block 824 is mounted on both the driven shaft 822 and the moving blade floating bracket 823, and the moving blade 825 is mounted on the moving blade floating block 824. This allows power to be effectively transmitted to the moving blade 825 through the driven shaft 822, ensuring that the moving blade 825 receives sufficient power for the shaving action. Simultaneously, the moving blade floating block 824, mounted on the driven shaft 822, plays a crucial role in buffering and shock absorption during powered shaving. The moving blade floating block 824 absorbs impacts and vibrations during shaving, resulting in a smoother shave. The moving blade floating block 824, through its elasticity and floating characteristics, buffers these external disturbances, reducing their impact on the moving blade 825 and thus extending its service life.

[0071] Example 4

[0072] like Figures 1 to 10 As shown, this embodiment discloses a shaver, including: the aforementioned dual-output drive mechanism; a handle housing assembly 9, on which a gear mechanism is partially disposed, a power mechanism 7 is disposed, and a moving blade assembly 8 is partially disposed; and a blade head housing assembly 10, on which a gear mechanism is partially disposed, a blade foil assembly 6 is disposed, and a moving blade assembly 8 is partially disposed.

[0073] The fourth aspect of this application discloses a shaver in which a portion of the gear mechanism, a portion of the power mechanism, and a portion of the moving blade assembly 8 are located on the handle housing assembly 9. This contributes to a compact design of the shaver. By rationally arranging these components in this area, space can be effectively utilized, avoiding the excessive space occupied by components scattered in different locations, resulting in a smaller overall size of the shaver, making it easier to carry and use. Simultaneously, the handle housing assembly 9 provides structural support for these components, ensuring the stable and normal operation of each mechanism. The gear mechanism, the foil assembly 6, and the moving blade assembly 8 are all located on the head housing assembly 10. This allows the components within the head housing assembly 10 to work collaboratively, ensuring more synchronized and smooth rotation of the foil assembly 6 and the moving blade assembly 8. Furthermore, the head housing assembly 10 can absorb some impact force, reducing the risk of damage to the foil assembly 6 and the moving blade assembly 8, and extending the service life of the components.

[0074] like Figure 9As shown, in addition to the features of the above embodiments, the present embodiment is further defined as: the handle housing assembly 9 comprises a handle housing body 91, a first inner housing 92, a second inner housing 93, a first support plate 94, a second support plate 95 and a third support plate 96, the first inner housing 92 is arranged on the handle housing body 91, the second inner housing 93 is arranged on the first inner housing 92, the first support plate 94 is arranged on the second inner housing 93, the second support plate 95 is arranged on the first support plate 94, the third support plate 96 is arranged on the second support plate 95, and the head housing assembly 10 is arranged on the third support plate 96. By arranging the first inner housing 92 on the handle housing body 91 and the second inner housing 93 on the first inner housing 92, a basis for installing the power mechanism 7 is provided, and arranging the power mechanism 7 on the second inner housing 93 helps to optimize the internal space utilization of the shaver, so that the internal structure of the entire shaver can be more compact. Arranging the first support plate 94 on the second inner housing 93 provides a basis and position for installing the speed reduction mechanism 2, ensures that the speed reduction mechanism 2 can work normally, and guarantees stable speed reduction, and at the same time, the first support plate 94 also provides a fixing space for the power input mechanism 1, ensuring that the power source of the power mechanism 7 is transmitted, and maintaining the normal work of the shaver. Arranging the second support plate 95 on the first support plate 94 provides a position for installing the speed reduction mechanism 2, the first direction transmission mechanism 3 and the second direction transmission mechanism 4, and arranging the third support plate 96 on the second support plate 95 provides further structural support for the first direction transmission mechanism 3, the second direction transmission mechanism 4 and the first transmission output mechanism 5, ensuring that the cutter net can stably forward and reverse, and guaranteeing the continuity of the shaving process. At the same time, arranging the first transmission output mechanism 5 in the third support plate 96 can fully utilize the internal space of the shaver, improve the space utilization, and make the various components in the shaver compactly arranged, and also avoid mutual interference between the components. Arranging the moving cutter driving gear 81 on the third support plate 96 ensures that the power is transmitted to the head, and provides structural support for the rotation of the moving cutter.

[0075] As Figure 10As shown, in addition to the features of the above embodiments, the present embodiment is further limited that: the cutter head housing assembly 10 comprises a matching shell 101, a cutter head housing body 102, a support limiting plate member 103 and a plurality of cutter net shells 104, the matching shell 101 is arranged on the handle housing assembly 9, the cutter head housing body 102 is arranged on the matching shell 101, the support limiting plate member 103 is arranged on the cutter head housing body 102, and the plurality of cutter net shells 104 are arranged on the cutter head housing body 102. By arranging the matching shell 101 on the handle housing assembly 9, the cutter net assembly 6 and the moving cutter assembly 8 are connected, and the integrity of the shaver is realized. By arranging the cutter head housing body 102 on the matching shell 101, the cutter net assembly 6 and the moving cutter assembly 8 inside are physically protected. During daily use, the shaver may be subjected to various accidents, such as falling, collision, etc. The cutter head housing body 102 can effectively reduce the direct impact on the cutter net assembly 6 and the moving cutter assembly 8, and reduce the risk of component damage. By arranging the support limiting plate member 103 on the cutter head housing body 102, the driven gear 821 and the moving cutter 842 can be accurately positioned. During the working process of the shaver, the position accuracy of the driven gear 821 and the moving cutter 825 is crucial for power transmission and shaving effect. The support limiting plate member 103 can fix the driven gear 821 and the moving cutter 842 in the appropriate position, avoiding the situation that gear misalignment leads to poor power transmission. By arranging the plurality of cutter net shells 104 on the cutter head housing body 102, the cutter net assembly 6 is physically protected against external impact and collision, preventing the cutter net of the cutter net assembly 6 from breaking or deforming, and prolonging the service life of the cutter net assembly 6.
