Description

Technical Field

[0001] This application relates to the field of shaver technology, and in particular to a reciprocating electric shaver with a self-cleaning function. Background Technology

[0002] In recent years, with the improvement of people's living standards, the personal care products industry has developed rapidly. Electric shavers, as an essential daily grooming tool for men, have seen continuous technological advancements. From the initial simple manual shavers to today's electric shavers, technological progress has made the shaving process more convenient, efficient, and comfortable. The advent of electric shavers has greatly saved people's time, improved the shaving experience, and allowed them to maintain a clean appearance more easily, presenting a good image in social and work settings. With the continuous development of technology, consumers have increasingly higher demands for the functions and performance of electric shavers, not only hoping for good shaving results but also expecting more additional functions to meet diverse needs.

[0003] In related technologies, to achieve the reciprocating motion of the blade assembly, an eccentric wheel is typically fixed on the output shaft of the drive motor. The eccentric wheel is connected to a drive rod, which in turn is connected to the blade assembly via a drive plate. This drives the blade assembly to reciprocate and complete the shaving operation. Regarding the cleaning of the shaver head system, there are two common methods. One is manual cleaning, where the user needs to remove the shaver head after use and carefully clean the beard residue between the blades with a brush or other tools. This method requires manual operation, is tedious, and cannot guarantee thorough cleaning. The other is water washing, where some shavers are designed to be washable. Users can directly rinse the shaver head under running water, using the force of the water flow to wash away beard residue. However, this method may not be effective in removing stubborn beard hairs stuck between the blades.

[0004] However, manual cleaning is not only time-consuming and laborious, but also, due to operational limitations, it's difficult to completely remove beard residue from inside the shaver head system. Over time, this accumulation can affect the shaving performance and lifespan of the shaver. While water washing is relatively more convenient, it still cannot guarantee the complete removal of beard hairs from the gaps between the blades in some complex shaver head systems. Furthermore, frequent washing may damage the internal structure of the shaver, reducing its reliability and stability. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a reciprocating electric shaver with a self-cleaning function.

[0006] A reciprocating electric shaver with a self-cleaning function includes a body, a blade head system disposed on the top of the body, and a drive motor disposed within the body. The blade head system includes an outer mesh cover and a built-in reciprocating blade assembly. An eccentric wheel is fixed on the output shaft of the drive motor, and the eccentric wheel is connected to a drive rod. The drive rod is connected to the blade assembly via a drive plate to drive its reciprocating motion. The shaver also includes: A mechanically linked air pump module includes a dual-chamber air pump, which has a cylinder and a piston, and the piston divides the inside of the cylinder into a first chamber and a second chamber. The piston is equipped with a first intake check valve, a first exhaust check valve, a second intake check valve, and a second exhaust check valve; The air blowing channel is connected to the first exhaust check valve and the second exhaust check valve via an exhaust hose, and its outlet leads to the inside of the cutter head system. The air intake channel is connected to the first and second air intake check valves via an air intake hose, and its inlet leads to the inside of the cutter head system. The dust collection chamber is located on the path of the air intake channel and upstream of the air inlet of the dual-chamber air pump.

[0007] By adopting the above technical solution, the power of the drive motor is used to make the blade assembly reciprocate to shave, and at the same time the power is transmitted to the piston, so that the volume of the first chamber and the second chamber alternately changes, realizing the simultaneous blowing and suction. A continuous airflow circulation is formed inside the shaving head system, which blows away the stuck beard and sucks it into the dust collection chamber for collection, realizing the self-cleaning of the shaving head system and avoiding beard residue in the gaps between the blade teeth. Moreover, the mechanical linkage realizes the reuse of power, and the filter screen in the dust collection chamber can prevent beard stubble from entering the air pump, ensuring the reliability of the air pump.

This allows the drive motor to rotate and drive the T-shaped rocker arm to slide back and forth in the sliding groove of the support plate. In turn, the power rod drives the piston to make linear reciprocating motion in the cylinder, realizing power transmission. This synchronizes the mechanical linkage air pump module with the shaving action of the shaver, achieving self-cleaning of the shaver head system.

[0010] Optionally, a relief groove is provided in the middle of the cylinder, the power rod passes through the relief groove and is threadedly connected to the piston, and the piston surface always blocks the relief groove during the sliding process.

When the piston moves, compressed air can enter the air blowing channel through the exhaust hose and blow it onto the blade assembly to loosen the embedded beard. At the same time, the beard-containing air in the beard storage chamber of the blade head is sucked into the dust collection chamber, realizing the self-cleaning of the blade head system and forming a continuous airflow circulation to improve cleaning efficiency.

[0014] Optionally, the air blowing channel includes a plastic guide fixed inside the outer mesh cover, and the top of the plastic guide has an array of miniature air outlet holes arranged longitudinally along the blade assembly.

[0015] By adopting the above technical solution, the plastic guide is fixed inside the outer mesh cover and has a micro air outlet array arranged longitudinally along the top of the blade assembly. Compressed air can be blown onto the blade assembly through the micro air outlet of the plastic guide to loosen the stuck beard. It can also ensure that the airflow sprayed from the micro air outlet covers the blade head of the blade assembly, realize the self-cleaning of the blade head system, and prevent the cut beard from remaining in the gap between the blade teeth.

[0016] Optionally, the dust collection chamber is made of metal and is magnetically connected to the inner wall of the blade storage chamber via a magnetic absorbing plate.

[0017] By adopting the above technical solution, the dust collection chamber is made of metal and is magnetically connected to the inner wall of the shaving head's storage chamber via a magnetic plate. This makes it easier for users to remove the dust collection chamber to clean their beard after shaving, making the cleaning of the shaver more convenient.

[0018] Optionally, the inlet of the air intake channel is located at the bottom of the blade storage chamber, which is located below the blade system and communicates with the swing space of the blade assembly.

[0019] By adopting the above technical solution, a hair storage chamber for the shaving head is set below the shaving head system and communicates with the swing space of the blade assembly. The air intake is placed at the bottom of the hair storage chamber, so that the air containing beard in the hair storage chamber can be effectively drawn into the dust collection chamber, which facilitates the collection and cleaning of beard produced during shaving, realizes the self-cleaning of the shaving head system, and avoids beard residue in the gap between the blade teeth.

[0021] By adopting the above technical solution, a rubber vibration damping pad is set between the drive plate and the body, and a compressible through hole is opened in the vibration damping pad, which can increase the compressibility and elasticity of the vibration damping pad, separate the blade assembly from the drive motor, prevent stubble from entering the drive motor, and ensure the normal operation of the blade assembly.

[0022] Optionally, a support plate is fixed inside the main body, which separates the drive motor from the space where the drive plate is located, and the T-shaped rocker arm is slidably installed in the sliding groove of the support plate.

[0023] By adopting the above technical solution, the support plate separates the drive motor from the space where the drive plate is located, preventing stubble from entering the drive motor; the T-shaped rocker arm is slidably installed in the sliding groove of the support plate, so that after the drive motor rotates, the vertical rod of the T-shaped rocker arm can slide back and forth in the sliding groove, thereby transmitting the power of the drive motor to the piston, realizing power reuse, driving the air pump module to work, and realizing the self-cleaning of the cutter head system.

[0024] Optionally, sealing blocks are fixed at both ends of the piston, and the sealing blocks cooperate with the cylinder plug to form an airtight cavity, and lubricating oil is coated between the piston and the cylinder inner wall.

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0030] A reciprocating electric shaver with self-cleaning function, as described in the reference Figure 1 , Figure 2 , Figure 3The device includes a main body 1, a blade system, a drive motor 2, a mechanically linked air pump module 3, an air blowing channel, an air suction channel, and a dust collection chamber 4. The mechanically linked air pump module 3 is connected to the output shaft of the drive motor 2 via a power conversion mechanism. The air blowing channel inlet is connected to the exhaust port of the air pump module 3, and its outlet leads to the interior of the blade system. The air suction channel outlet is connected to the air inlet of the air pump module 3, and its inlet leads to the interior of the blade system. The dust collection chamber 4 is located on the path of the air suction channel and upstream of the air inlet of the air pump module 3. This design enables the blade system to self-clean, preventing cut beard hairs from remaining in the gaps between the blade teeth.

[0031] Reference Figure 3 , Figure 4 , Figure 5 The power conversion mechanism includes an eccentric wheel 5 fixedly connected to the drive shaft of the drive motor 2, and a drive rod 6 is engaged with the eccentric wheel 5. The drive rod 6 includes a engaging portion 601 and a rotating portion 602. The engaging portion 601 of the drive rod 6 is inserted into the eccentric rod of the eccentric wheel 5. Simultaneously, a drive plate 7 is engaged with the drive rod 6. The upper part of the drive plate 7 engages with the blade assembly 8 in the cutter head system, and the lower part of the drive plate 7 has a first drive groove 9. The rotating portion 602 of the drive rod 6 extends into the first drive groove 9, and the extension direction of the first drive groove 9 is perpendicular to the movement direction of the blade assembly 8. This allows the drive motor 2 to rotate, driving the blade assembly 8 to reciprocate. Furthermore, a ball bearing 603 can be embedded at the contact point between the rotating portion 602 of the drive rod 6 and the bottom of the first drive groove 9 to further reduce the friction between the drive rod 6 and the drive plate 7.

[0032] Reference Figure 3 , Figure 4 A connecting groove 10 is provided on the top of the main body 1 near the cutter head system. A limiting ring 11 is fixedly connected to the side of the main body 1 facing the cutter head system via the connecting groove 10. The drive plate 7 is installed in the connecting groove 10, and a rubber damping pad 12 is fixedly connected to its side. The damping pad 12 abuts against the limiting ring 11 and the inner wall of the connecting groove 10, thereby separating the blade assembly 8 from the drive motor 2. In addition, several compressible through holes are provided in the damping pad 12 to increase the compressibility and elasticity of the damping pad 12 and ensure the normal operation of the blade assembly 8. The upper surface of the drive plate 7 and the inner wall of the limiting ring 11 are covered with a rubber pad 13 by adhesive to further prevent stubble from entering the drive motor 2.

[0033] Reference Figure 3 , Figure 6A support plate 14 is detachably connected to the inner wall of the main body 1 between the drive plate 7 and the drive motor 2, and the support plate 14 separates the space where the drive motor 2 and the drive plate 7 are located. In addition, a sliding groove 15 is provided on the surface of the support plate 14 near the drive plate 7, and a T-shaped rocker arm 16 is installed in the sliding groove 15. The crossbar of the T-shaped rocker arm 16 has a second drive groove 17, and it is sleeved on the drive rod 6 through the second drive groove 17, so that the vertical bar of the T-shaped rocker arm 16 slides back and forth in the sliding groove 15 after the drive motor 2 rotates.

[0034] Reference Figure 3 , Figure 6 , Figure 7 The mechanically linked air pump module 3 includes a dual-chamber air pump fixedly connected to the upper surface of the support plate 14. The dual-chamber air pump has a cylinder 301 and a piston 302. The cylinder 301 consists of a connecting cylinder and two airtight cylinders, with the opposing portions of the two airtight cylinders fixedly connected to a cap 303 by welding. A clearance groove 18 is formed on the surface of the connecting cylinder 301, directly opposite the T-shaped rocker arm 16. The piston 302 is shaped to match the connecting cylinder, its outer surface abutting against the inner wall of the cylinder 301, and its length is greater than the length of the clearance groove 18. A power rod 304 is threadedly connected to the middle portion of the piston 302. The power rod 304 extends out of the cylinder 301 through the clearance groove 18, and its end is connected to the vertical rod of the T-shaped rocker arm 16 via a hinge shaft. This allows the vertical rod of the T-shaped rocker arm 16 to slide back and forth in the sliding groove 15, thereby driving the piston 302 to slide along the opening direction of the relief groove 18. During the sliding process of the piston 302, its surface always blocks the relief groove 18, thus preventing gas leakage in the cylinder 301.

[0035] Reference Figure 7 Both ends of the piston 302 are fixed with sealing blocks 305. The shape of the sealing blocks 305 matches the airtight cylinder, and they cooperate with the corresponding plugs 303 to form airtight cavities within the cylinder 301. One of these cavities is designated as the first chamber 19, and the other as the second chamber 20. Furthermore, lubricating oil is coated between the piston 302 and the inner wall of the cylinder 301, which reduces wear between the piston 302 and the cylinder 301 while improving the sealing performance of the first chamber 19 and the second chamber 20. After the cylinder 301, plugs 303, and piston 302 are installed, the first chamber 19 and the second chamber 20 are filled with everyday air.

[0037] Reference Figure 7 , Figure 8 The main body 1 has a blade storage chamber 26 within the space where the blade assembly 8 is located. There are two blade storage chambers 26, which are respectively located in the direction of movement of the blade assembly 8 and below the blade assembly 8. Both the first intake check valve 21 and the second intake check valve 23 are connected to intake hoses 25. One end of each intake hose 25, which is far from the cylinder 301, passes through the blade storage chambers 26 located close to each other, allowing the gas in the blade storage chambers 26 to flow into the cylinder 301 through the intake hoses 25.

[0038] Reference Figure 4 , Figure 7 , Figure 8 A filter cover 27 is fixedly connected to the end of the intake hose 25 away from the cylinder 301. The filter cover 27 is fixedly connected to the inner wall of the stubble storage cavity 26, and the surface of the filter cover 27 has several filter holes. In addition, a magnetic absorbing plate 28 is embedded in the inner wall of the stubble storage cavity 26, and a metal dust collection bin 4 is installed inside the stubble storage cavity 26. The outer surface of the dust collection bin 4 abuts against the inner wall of the stubble storage cavity 26, and its lower outer bottom surface is magnetically attracted to the magnetic absorbing plate 28. A clearance hole is provided at the filter cover 27, so that the dust collection bin 4 can be fitted over the filter cover 27 through the clearance hole. In addition, a filter screen 29 is fixedly connected to the bottom surface of the dust collection bin 4, and the filter screen 29 covers the filter cover 27, so that it and the filter cover 27 cooperate to form a double filtration protection to prevent stubble from entering the cylinder 301 through the intake hose 25.

[0039] Reference Figure 9 The outer mesh cover 30 of the blade system is snapped into the main body 1. Two plastic air guides 31 are fixedly connected inside the outer mesh cover 30, and are respectively positioned on both sides of the blade assembly 8. The plastic air guides 31 have a hollow interior, with several miniature air outlets 32 facing the blade assembly 8 at their top. These miniature air outlets 32 are arranged in a longitudinal array along the blade assembly 8 to ensure that the airflow from the miniature air outlets 32 covers the blade tip of the blade assembly 8. Additionally, a docking hole 33 is provided at the bottom of the plastic air guide 31, and a sealing ring 34 is fixedly connected to the inner wall of the docking hole 33.

[0040] Reference Figure 7 , Figure 8 , Figure 9Both the first exhaust check valve 22 and the second exhaust check valve 24 are connected to exhaust hoses 35. The exhaust hoses 35 extend through the limiting ring 11 into the space containing the blade assembly 8, allowing gas from the cylinder 301 to flow into the space containing the blade assembly 8. An exhaust seat 36 is fixedly connected to the end of the exhaust hose 35 away from the cylinder 301. The exhaust seat 36 is fixedly connected to the surface of the limiting ring 11 near the blade assembly 8. Furthermore, a mating ring 37 protruding towards the blade assembly 8 is integrally formed on the exhaust seat 36. The exhaust seats 36 on the two exhaust hoses 35 are respectively located on both sides of the blade assembly 8 laterally. When the outer mesh cover 30 is installed in place, the mating rings 37 on the two exhaust seats 36 mate with the mating holes 33 on the plastic guide members 31, allowing one plastic guide member 31 to be inserted into the mating ring 37 of one exhaust seat 36 through the mating hole 33. This allows the gas in cylinder 301 to flow into plastic guide 31 through exhaust pipe 35, and then be blown toward blade assembly 8 through miniature air outlet 32.

[0041] The implementation principle of this application embodiment is as follows: When the user starts the shaver, the drive motor 2 rotates, driving the eccentric wheel 5 fixed on the output shaft to rotate. The eccentric wheel 5 drives the drive plate 7 through the drive rod 6, causing the reciprocating blade assembly 8 to perform high-speed reciprocating motion for shaving. At the same time, the drive rod 6 drives the T-shaped rocker arm 16 to slide back and forth in the sliding groove 15 of the support plate 14, and the T-shaped rocker arm 16 drives the piston 302 to perform linear reciprocating motion in the cylinder 301 through the power rod 304.

[0042] As piston 302 moves, the volumes of the first chamber 19 and the second chamber 20 change alternately: When the piston 302 moves toward the first chamber 19, the volume of the first chamber 19 decreases and the pressure increases. The first exhaust check valve 22 opens, and compressed air enters the blowing channel through the exhaust hose 35. It is blown toward the blade assembly 8 through the miniature air outlet 32 ​​of the plastic guide 31 to loosen the embedded beard. At the same time, the volume of the second chamber 20 increases and the pressure decreases. The second intake check valve 23 opens, and the beard-containing air in the beard storage chamber 26 is drawn into the dust collection chamber 4. After being filtered by the filter screen 29, the clean air enters the second chamber 20 through the intake hose 25.

[0043] When the piston 302 moves toward the second chamber 20, the process is reversed: the second chamber 20 compresses and blows air, while the first chamber 19 draws air in under negative pressure.

[0044] The blowing and suction processes are synchronized, creating a continuous airflow circulation within the shaving head system. Blown-out hairs are drawn into the dust collection chamber 4 by negative pressure, and the filtered air is then recycled by the air pump. After shaving, the user can remove the dust collection chamber 4 using the magnetic attachment 28 to clean the hairs. Throughout the process, mechanical linkage enables power reuse, synchronized blowing and suction improves cleaning efficiency, and the pre-filter ensures the reliability of the air pump, thus achieving a highly efficient and automatic self-cleaning function. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
