Description

Technical Field

[0001] This utility model relates to the field of personal care electrical appliance technology, and more specifically, to a reciprocating electric shaver transmission structure. Background Technology

[0002] Electric shavers are mainly divided into two categories: rotary and reciprocating. Reciprocating electric shavers, due to the high-speed linear reciprocating motion of their blades, have excellent cutting efficiency for coarse, thick, and dense beards, resulting in a cleaner shave. They are especially suitable for the characteristics of Asian men's beards and therefore hold an important position in the market.

[0003] Although reciprocating shavers have a clear advantage in shaving cleanliness, their inherent technical shortcomings have long plagued users and manufacturers, mainly in the following aspects:

[0004] 1. Most mainstream designs adopt a single eccentric wheel drive structure. Its inherent unbalanced mass will generate strong periodic excitation force when running at high speed, resulting in poor hand-held experience and significant operating noise.

[0005] 2. Many transmission mechanisms rely on simple grooves or limited fulcrums for guidance, making it difficult to accurately constrain the movement trajectory of the cutter head at high speeds. This insufficient guidance can easily lead to unexpected wobble and vibration in the cutter head assembly, not only generating additional noise but also causing wear and tear on transmission components due to uneven wear, thereby shortening the service life of the entire mechanism.

[0006] 3. Sliding friction is common at transmission joints. If the friction pair material is not selected properly, wear and increased clearance are likely to occur after long-term high-speed operation, resulting in abnormal transmission noise, reduced efficiency, and even the need for regular lubrication and maintenance, which affects the long-term reliability of the product and the user experience. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reciprocating electric shaver transmission structure, which aims to solve the problems mentioned in the background art.

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A reciprocating electric shaver drive structure includes:

[0010] A housing, wherein a connecting frame is fixedly installed between the inner walls of the housing, and a tool holder is embedded in the outer wall of the connecting frame. Multiple outer blade nets are installed on the outer wall of the tool holder via snap-fits. Multiple inner blades are correspondingly and movably embedded inside the tool holder, and each inner blade has a groove at its bottom.

[0011] The transmission mechanism, located on the housing, is used to drive multiple internal blades.

[0012] As a preferred embodiment of this utility model, the transmission mechanism includes multiple guide rods, each of which is fixedly installed between the inner walls of the connecting frame. A main drive block and a secondary drive block are movably sleeved between the outer surfaces of every two guide rods. A linkage arm is rotatably installed on one side of the outer wall of the connecting frame, and the linkage arm is rotatably connected to the main drive block and the secondary drive block.

[0013] As a preferred embodiment of this utility model, a drive motor is installed between the inner walls of the connecting frame, an eccentric wheel is sleeved on the output end of the drive motor, and a corresponding mounting groove is opened on the outer wall of one side of the main drive block.

[0014] As a preferred embodiment of this utility model, multiple magnet blocks are fixedly embedded on one side of the outer wall of both the tool holder and the connecting frame.

[0015] As a preferred embodiment of this utility model, multiple limiting posts are fixedly installed on the outer walls of the tool holder and the multiple inner blades, and a spring is sleeved between the outer surfaces of every two limiting posts.

[0016] As a preferred embodiment of this utility model, a protrusion is provided on one side of the outer wall of the connecting frame.

[0017] As a preferred embodiment of this utility model, a sealing ring is fixedly installed between the connecting frame and the outer shell.

[0018] Beneficial effects

[0019] Compared with the prior art, this utility model provides a reciprocating electric shaver transmission structure, which has the following advantages:

[0020] 1. In this design, the housing provides protection for the connecting frame, blade holder, outer blade net, inner blade, and transmission mechanism. The transmission mechanism facilitates the reciprocating motion of the inner blade, which, in conjunction with the outer blade net, easily cuts the beard hairs that have entered the outer blade net, thus achieving the shaving function. At the same time, the transmission mechanism enables synchronous, reverse, and constant-speed linear reciprocating motion in the same plane, which not only balances the inertial force but also concentrates the moving parts in the same space, greatly saving longitudinal and lateral space.

[0021] 2. In this solution, the eccentric wheel is easily driven to rotate by the drive motor. At the same time, the eccentric wheel and the mounting groove on the main drive block cooperate to facilitate the continuous reciprocating motion of the main drive block, which facilitates the use of the transmission mechanism. By linking the eccentric wheel with the main drive block and the auxiliary drive block, the vibration during the use of the shaver is reduced, thereby reducing noise and making the structure more compact.

[0022] 3. In this design, the main drive block slides on two corresponding guide rods, and in conjunction with the linkage arm, it facilitates the movement of the secondary drive block in the opposite direction. In conjunction with the groove on the inner blade, it facilitates the movement of the inner blade. Through three parallel guide rods, and with oil-impregnated bearings installed on both the main drive block and the secondary drive block, the movement of the main drive block and the secondary drive block is more stable and maintenance-free, thereby effectively improving the noise reduction effect and service life, and making it easier to assemble and with higher structural rigidity.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] Example:

[0034] Please see Figure 1-7 A reciprocating electric shaver drive structure includes:

[0035] The housing 1 and the transmission mechanism 6 are included. A connecting frame 2 is fixedly installed between the inner walls of the housing 1. A tool holder 3 is embedded in the outer wall of the connecting frame 2. Multiple outer blade nets 4 are installed on the outer wall of the tool holder 3 by means of a buckle. Multiple inner blades 5 are correspondingly and movably embedded inside the tool holder 3. Each inner blade 5 has a groove at its bottom. The transmission mechanism 6 is located on the housing.

[0036] In this embodiment, the housing 1 provides protection for the connecting frame 2, the blade holder 3, the outer blade net 4, the inner blade 5, and the transmission mechanism 6. The transmission mechanism 6 facilitates the reciprocating motion of the inner blade 5, which, in conjunction with the outer blade net 4, facilitates the cutting of beard hairs that enter the outer blade net 4, thus achieving the shaving function. At the same time, the transmission mechanism 6 enables synchronous, reverse, and constant-speed linear reciprocating motion in the same plane, which not only balances the inertial force but also concentrates the moving parts in the same space. Compared with designs that require multiple independent motors or complex transmission chains, this greatly saves longitudinal and lateral space.

[0037] Please refer to the specific details. Figure 2 and Figure 5-7 As shown, the transmission mechanism 6 includes multiple guide rods 601. Each guide rod 601 is fixedly installed between the inner walls of the connecting frame 2. A main drive block 602 and a secondary drive block 603 are movably sleeved between the outer surfaces of every two guide rods 601. A linkage arm 604 is rotatably installed on one side of the outer wall of the connecting frame 2, and the linkage arm 604 is rotatably connected to the main drive block 602 and the secondary drive block 603.

[0038] In this embodiment, the main drive block 602 slides on the corresponding two guide rods 601, and in conjunction with the linkage arm 604, it facilitates the movement of the secondary drive block 603 in the opposite direction. In conjunction with the groove on the inner blade 5, it facilitates the movement of the inner blade 5. Through the three parallel guide rods 601, and with oil-impregnated bearings provided on both the main drive block 602 and the secondary drive block 603, the movement of the main drive block 602 and the secondary drive block 603 is more stable and maintenance-free, thereby effectively improving the noise reduction effect and service life, and making it easier to assemble and with higher structural rigidity.

[0039] Please refer to the specific details. Figure 5-7 As shown, a drive motor 605 is installed between the inner walls of the connecting frame 2. An eccentric wheel 606 is sleeved on the output end of the drive motor 605, and a corresponding mounting groove is opened on the outer wall of one side of the main drive block 602.

[0040] In this embodiment, the drive motor 605 facilitates the rotation of the eccentric wheel 606. At the same time, the eccentric wheel 606 and the mounting groove on the main drive block 602 cooperate to facilitate the continuous reciprocating motion of the main drive block 602, which facilitates the use of the transmission mechanism 6. Through the linkage of the eccentric wheel 606, the main drive block 602, and the auxiliary drive block 603, the vibration during the use of the shaver is reduced, thereby reducing noise and making the structure more compact.

[0041] Please refer to the specific details. Figure 3 As shown, multiple magnet blocks 7 are fixedly embedded on one side of the outer wall of both the tool holder 3 and the connecting frame 2.

[0042] In this embodiment, the corresponding magnet blocks 7 attract each other, which facilitates the installation and disassembly of the tool holder 3 and the connecting frame 2.

[0043] Please refer to the specific details. Figure 6 As shown, multiple limiting posts 8 are fixedly installed on the outer walls of the tool holder 3 and multiple inner blades 5, and a spring 9 is sleeved between the outer surfaces of every two limiting posts 8.

[0044] In this embodiment, the corresponding limiting post 8 and spring 9 work together to ensure that the inner blade 5 can fit tightly against the corresponding outer blade net 4, thereby improving the shaver's performance.

[0045] Please refer to the specific details. Figure 4 As shown, a protrusion 10 is provided on one side of the outer wall of the connecting frame 2.

[0046] In this embodiment, a protrusion 10 is provided on the connecting frame 2. The protrusion 10 facilitates the formation of a storage space on the connecting frame 2, which is convenient for collecting the shaved beard and thus facilitating subsequent cleaning.

[0047] Please refer to the specific details. Figure 4 As shown, a sealing ring 11 is fixedly installed between the connecting frame 2 and the housing 1.

[0048] In this embodiment, the sealing effect between the connecting frame 2 and the housing 1 is improved by the sealing ring 11, which reduces noise to a certain extent.

[0049] Working principle: In use, the drive motor 605 on the connecting frame 2 starts, driving the eccentric wheel 606 to rotate. Since the eccentric wheel 606 is compatible with the mounting groove on the main drive block 602, and both the main drive block 602 and the auxiliary drive block 603 are movably mounted on the guide rod 601, the main drive block 602 can be easily driven to reciprocate continuously. Because the linkage arm 604 connects the main drive block 602 and the auxiliary drive block 603, it drives the auxiliary drive block 603 to reciprocate in the opposite direction to the main drive block 602. At this time, the main drive block 602 and the auxiliary drive block 603 drive the corresponding inner blade 5 to reciprocate inside the blade holder 3, working in conjunction with the outer blade net 4 to cut the beard. This utility model also features high wear resistance, long lifespan, and low noise.

[0050] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
