Description

Technical Field

[0001] This invention relates to the field of automatic cleaning technology for multi-head electric shavers, specifically to an automatic cleaning structure for a multi-head electric shaver. Background Technology

[0002] Razors play a very important role in men's appearance management. Most adult men shave every one to two days. Razors that are not cleaned in time or are not cleaned properly can harbor a large number of bacteria, which can not only damage the skin but also reduce the lifespan of the razor.

[0003] Most electric shavers are now washable, but they have a foil and a more complex structure. They also usually break down the beard after shaving, creating beard powder, which results in a large amount of beard debris inside the shaver head.

[0004] Existing washable shavers typically require opening the shaver head cavity for cleaning, allowing direct rinsing with water. However, due to the friction and static electricity generated by the beard dust, it adheres to the inner wall of the upper cavity of the shaver, making thorough cleaning difficult with natural rinsing. Furthermore, the complex structure of the shaver head, foil, and locking mechanism can create impact blind spots when directly rinsing the stationary shaver head and foil, potentially pushing beard dust directly into these areas, resulting in incomplete cleaning. Summary of the Invention

[0005] The technical problem of this invention is to provide an automatic cleaning structure for a multi-head electric shaver. High-pressure water is injected from the water inlet on the side wall of the top shell into a semi-enclosed cavity formed by the top shell, base, and rubber pad. The water flow forms a vortex in the upper cavity of the shaver, which is then discharged from the top of the top shell, effectively removing beard debris from the upper cavity. Subsequently, the high-pressure water flow is guided by a rubber tube to flush the filter screen mounted on the curved plate, cleaning the beard debris behind the filter screen. A rotating vortex is formed behind the filter screen, cleaning the complexly constructed shaver head. Finally, the locking frame is cleaned, thus cleaning all the beard debris from the shaver's cavity and components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic cleaning structure for a multi-head electric shaver, comprising a top shell, a base, a locking frame, three shaver heads, and three filters. One side of the top shell is rotatably connected to the outer edge of the base. The upper end of the top shell has three through holes arranged in a circular array along its vertical axis, each containing three arc-shaped rubber tubes. The three rubber tubes are respectively inserted into the three through holes. A chamfered plate is commonly provided at the upper end of the three rubber tubes, and the curvature of the chamfered plate is similar to that of the upper surface of the top shell. Similarly, the inverted arc plate has three insertion holes circumferentially opened along its vertical axis, and the three rubber tubes are respectively inserted into the three insertion holes. Each filter screen is respectively snapped into the insertion hole, and each blade head is rotatably connected to the inner wall of each filter screen. A column is vertically fixed in the center of the inverted arc plate, and the locking frame is snapped into the outer wall of the column. The locking frame presses the blade head against the inner wall of the filter screen. The top shell has a water injection hole, and a rubber plug is placed in the water injection hole. A rubber pad is placed on the contact surface between the top shell and the base.

[0007] As a further embodiment of the present invention, it includes three universal rotating heads, which are arranged in a circular array on the base along the vertical axis of the base. Each rubber tube has a brush mechanism on its inner wall. The brush mechanism includes two support rings, which are respectively fixedly connected to the inner wall of the rubber tube. A steel wire is rotatably connected between the two support rings. Brush bristles are spirally wound on the outer wall of the steel wire. A first transmission seat is fixedly provided at the lower end of the steel wire, and the first transmission seat is sleeved on the universal rotating head.

[0008] As a further embodiment of the present invention, two first sector plates are fixedly disposed on the outer wall of the steel wire, and two second sector plates are fixedly disposed on the inner wall of the rubber tube, wherein the first sector plates and the second sector plates have only one side surface coplanar.

[0009] As a further embodiment of the present invention, a first circular plate is snapped onto the outer wall of the upper end of the column, and three horizontal plates are fixedly connected to the first circular plate in a circular array along its vertical axis. A second shaft is rotatably provided on the side wall of each horizontal plate. An adapter is fixedly connected to the lower end of the second shaft, and the lower end of the adapter is snapped into the center of the cutter head. A first bevel gear is coaxially fixedly provided on the upper end of the second shaft, and a drive device for driving the first bevel gear to rotate is connected to the upper end of the first bevel gear.

[0010] As a further embodiment of the present invention, the driving device includes a ring sleeve, the upper end of the first circular plate is rotatably provided with the ring sleeve, the lower end of the ring sleeve is fixedly connected with a ring tooth plate, the ring tooth plate meshes with a first bevel gear, the outer wall of the ring sleeve is fixedly connected with a plurality of fan blades in a ring array around its axis, and the inverted arc plate is provided with a diversion device for gathering water flow to drive the ring sleeve to rotate.

[0011] As a further embodiment of the present invention, the diversion device includes a vertical ring plate fixedly disposed on the upper end of the inverted arc plate, an upper arc plate being snapped onto the upper end of the vertical ring plate, a water outlet hole being vertically opened in the center of the upper arc plate, and the fan blade and the ring sleeve being located in the center of the water outlet hole.

[0012] As a further aspect of the present invention, the contact surfaces of the first sector plate and the second sector plate are made of friction-reducing material to reduce equipment friction and extend the service life of the equipment.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention injects high-pressure water from the water injection hole on the side wall of the top shell into a semi-enclosed cavity formed by the top shell, base, and rubber pad. The water flow forms a vortex in the upper cavity of the shaver, which is then discharged from the top of the top shell, thus efficiently removing beard debris from the upper cavity of the shaver. Subsequently, the high-pressure water flow is guided by the rubber tube to wash the filter screen installed on the curved plate, cleaning the beard debris behind the filter screen. A rotating vortex is formed at the rear of the filter screen, which cleans the complex blade head. Finally, the locking frame is cleaned, thus cleaning all the beard debris from the cavity and parts of the shaver.

[0015] 2. This invention utilizes the electric shaver's own power to drive the universal rotating head, which in turn drives the steel wire to rotate, which in turn drives the brush bristles to rotate. This accelerates water flow efficiency and cleans the rubber tubes, preventing bacterial growth within the cleaning structure itself. Furthermore, the steel wire's rotation drives the first sector plate to revolve, opening and closing with the second sector plate closely attached to its lower end. This intermittent opening and closing of the three rubber tubes causes fluctuations in water pressure within the shaver's upper cavity, thereby enhancing the shaver's cleaning effect and capability.

[0016] 3. This invention uses a high-speed water flow from the outlet hole in the center of the cavity formed by the inverted arc plate, the vertical ring plate, and the upper arc plate to drive the cutter head to rotate at high speed between the locking frame and the filter screen. This changes the position of the cutter head, preventing it from blocking the water flow and impacting parts of the locking frame, thus avoiding cleaning dead corners. Secondly, it avoids the cutter head from being in contact with the filter screen for a long time, which would cause vibration due to water flow impact, resulting in collision between the cutter head and the filter screen, leading to damage to the cutter head and a reduced lifespan.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7This invention provides a technical solution: an automatic cleaning structure for a multi-head electric shaver, comprising a top shell 9, a base 10, a locking frame 12, three shaver heads 13, and three filters 15. One side of the top shell 9 is rotatably connected to the outer edge of the base 10. The upper end of the top shell 9 has three through holes 14 arranged in a circular array along its vertical axis, each containing three arc-shaped rubber tubes 17. The three rubber tubes 17 are respectively inserted into the three through holes 14. A curved plate 18 is commonly provided at the upper end of the three rubber tubes 17. The curvature of the curved plate 18 is the same as that of the upper surface of the top shell 9. The plate 18 has three insertion holes 19 arranged in a ring along its vertical axis. Three rubber tubes 17 are respectively inserted into the three insertion holes 19. Each filter screen 15 is respectively snapped into the insertion hole 19. Each cutter head 13 is rotatably connected to the inner wall of each filter screen 15. A column 20 is vertically fixed in the center of the arc plate 18. A locking frame 12 is snapped into the outer wall of the column 20. The locking frame 12 presses the cutter head 13 against the inner wall of the filter screen 15. The top shell 9 has a water injection hole. A rubber plug 22 is installed in the water injection hole. A rubber pad 23 is installed on the contact surface between the top shell 9 and the base 10.

[0029] Before using this invention, the device must be assembled, such as... Figure 1 As shown, from Figure 1 Looking from top to bottom, this is the upper part of the device. The device adopts a vertical axis circular arrangement, without left, right, front, or back distinctions. This invention mainly demonstrates the cleaning structure of a conventional three-head electric shaver. When the shaver needs cleaning, the rubber stopper 22 is pulled out. Simultaneously, the locking frame 12, shaver head 13, and filter 15, originally located in the upper cavity of the shaver, are assembled into the column 20 inside the upper curved plate 18. The curved plate 18 and the top shell 9 have the same shape (the structure of the column 20 is the same as the internal structure of the top shell 9), and they are symmetrical about a certain horizontal plane between them. Tap water is connected to the water inlet through a hose, and the rubber tube 17 is inserted into the through hole 14 at the upper end of the top shell 9 (e.g., ...). Figure 1 As shown, the through hole 14 on the top shell 9 is normally used to hold the filter screen 15. The side wall of the through hole 14 is provided with a step so that the rubber tube 17 can be held in the through hole 14 and will not fall off.

[0030] When using this invention, the top shell 9 is closed, forming a semi-closed cavity with the base 10. Through the action of the rubber pad 23, only the upper part of the upper cavity of the shaver body is open to the outside (no air leakage occurs in the upper cavity during normal use, preventing beard hairs from falling out). With the top of the device facing downwards, water can flow directly into the rubber tube 17 under gravity, preventing the shaver body from getting wet (the discharged water contains beard hair fragments, preventing the water from impacting the body and causing water damage). (Bad problem) When the tap is turned on, water flows into the top shell 9, increasing the water flow so that the cavity formed between the top shell 9 and the base 10 is filled with water. The water is pressurized inside the top shell 9 and the base 10 and then discharged from the rubber tube 17 at the top of the device to the top of the device (the device is facing downwards during cleaning, which will not be described further). Because the water inlet and outlet directions of the top shell 9 are at a 90-degree angle, the pressure inside the top shell 9 and the base 10 can form a vortex, thereby quickly removing the beard debris from the inner wall of the cavity formed inside the top shell 9 and the base 10. The water quickly blends into the water and is carried by the water flow into the rubber tube 17. The water flow from the rubber tube 17 rapidly washes the filter screen 15, thereby removing the beard debris remaining on the filter screen 15. (Initially, due to the large amount of beard debris impacting the filter screen 15, the filter screen 15 may become clogged, causing an increase in pressure within the top shell 9 and base 10, increasing the vortex energy and thus better removing beard debris. Subsequently, the high-pressure water flow continuously impacts the filter screen 15, forcing the beard debris at the rear end of the filter screen 15 to detach. The filter screen 15 then functions normally. During shaving, the operator will remove the filter screen 15.) 5. When the water is rubbed on the face, the mesh of the filter 15 is normally tilted and opened on its surface. When the water flows through the through holes on the tilted filter 15, it will be deflected, thus forming a rotating vortex at the rear end of the filter 15. The high-pressure water flow after the filter 15 forms a vortex to rotate and wash the razor head 13, thereby washing away the beard debris on the complex razor head 13. Then the water flow impacts the locking frame 12, washing the locking frame 12 clean. Thus, the upper cavity of the razor, the filter, and the waste water finally flow out from the upper end of the curved plate 18.

[0031] This invention injects high-pressure water from the water injection hole on the side wall of the top shell 9 into the semi-enclosed cavity formed by the top shell 9, the base 10, and the rubber pad 23. The water flow forms a vortex in the upper cavity of the shaver, and is discharged from the upper part of the top shell 9, thereby efficiently removing beard debris from the upper cavity of the shaver. Subsequently, the high-pressure water flow is guided by the rubber tube 17 to wash the filter screen 15 installed on the curved plate 18, cleaning the beard debris at the rear end of the filter screen 15. A rotating vortex is formed at the rear end of the filter screen 15, thereby cleaning the complex blade head 13. Finally, the locking frame 12 is cleaned, thus cleaning all the cavities and parts of the shaver that contain beard debris.

[0032] As a further embodiment of the present invention, it includes three universal rotating heads 11, which are arranged in a circular array and rotatably mounted on the base 10 along the vertical axis of the base 10. Each rubber tube 17 has a brush mechanism on its inner wall. The brush mechanism includes two support rings 25, which are respectively fixedly connected to the inner wall of the rubber tube 17. A steel wire 26 is rotatably connected between the two support rings 25. Brush bristles 27 are spirally wound on the outer wall of the steel wire 26. A first transmission seat 28 is fixedly mounted on the lower end of the steel wire 26 and is sleeved on the universal rotating head 11. Two first sector plates 30 are fixedly mounted on the outer wall of the steel wire 26, and two second sector plates 31 are fixedly mounted on the inner wall of the rubber tube 17. The first sector plates 30 and the second sector plates 31 have only one side coplanar.

[0033] When using this invention, when water is injected into the cavity formed by the top shell 9 and the base 10, the shaver power is turned on, the universal rotating head 11 rotates, the rotation of the universal rotating head 11 drives the first transmission seat 28 to rotate, the rotation of the first transmission seat 28 drives the steel wire 26 to rotate on the support ring 25 inside the rubber tube 17, and the rotation of the steel wire 26 drives the bristles 27 to rotate (e.g., Figure 3 As shown, the steel wire 26 is flexible and rotates at the same speed at both ends (as long as the folding angle of the steel wire 26 is greater than 100 degrees). The spiral bristles 27 rotate to drive the water flow to accelerate within the rubber tube 17. At the same time, the bristles 27 scrape the inner wall of the rubber tube 17, thereby cleaning the beard debris from the inner wall of the rubber tube 17 and preventing beard debris from remaining on the cleaning structure and causing bacterial growth. The rotation of the steel wire 26 drives the two first sector plates 30 to rotate on the fixed second sector plate 31, thereby opening and closing the rubber tube 17. The three rubber tubes 17 are closed intermittently, which causes the water pressure inside the upper cavity of the shaver to fluctuate, forming a stronger vortex and enhancing the cleaning efficiency and intensity of beard debris.

[0034] This invention utilizes the power of the electric shaver itself to drive the universal rotating head 11 to rotate. The rotation of the universal rotating head 11 drives the steel wire 26 to rotate, and the rotation of the steel wire 26 drives the bristles 27 to rotate. This accelerates the water flow efficiency and cleans the rubber tubes 17, preventing bacterial growth in the cleaning structure itself. Furthermore, the rotation of the steel wire 26 drives the first sector plate 30 to revolve, and it opens and closes with the second sector plate 31 that is closely attached to the lower end. This causes the three rubber tubes 17 to intermittently open and close, resulting in fluctuations in the water pressure inside the upper cavity of the shaver, thereby improving the shaver's cleaning effect and capability.

[0035] As a further embodiment of the present invention, a first circular plate 35 is snapped onto the outer wall of the upper end of the column 20. Three horizontal plates 36 are fixedly connected to the first circular plate 35 in a circular array along its vertical axis. A second shaft 37 is rotatably mounted on the side wall of each horizontal plate 36. An adapter 38 is fixedly connected to the lower end of the second shaft 37, and the lower end of the adapter 38 is snapped into the center of the cutter head 13. A first bevel gear 42 is coaxially fixed to the upper end of the second shaft 37. A driving device for driving the first bevel gear 42 to rotate is connected to the upper end of the first bevel gear 42. The driving device includes a ring sleeve 39. A ring sleeve 39 is rotatably mounted on the upper end of a circular plate 35. A ring tooth plate 40 is fixedly connected to the lower end of the ring sleeve 39. The ring tooth plate 40 meshes with a first bevel gear 42. Multiple fan blades 41 are fixedly connected in a ring array around the outer wall of the ring sleeve 39 along its axis. A flow guiding device for gathering water flow to drive the ring sleeve 39 to rotate is provided on the inverted arc plate 18. The flow guiding device includes a vertical ring plate 43 fixedly mounted on the upper end of the inverted arc plate 18. An upper arc plate 44 is snapped onto the upper end of the vertical ring plate 43. A water outlet hole 45 is vertically opened in the center of the upper arc plate 44. The fan blades 41 and the ring sleeve 39 are located in the center of the water outlet hole 45.

[0036] When using this invention, as Figure 2 , 3 As shown in Figure 4, water flows out at high speed through the outlet 45 in the center of the cavity formed by the inverted arc plate 18, the vertical ring plate 43, and the upper arc plate 44 (where the inverted arc plate 18, the vertical ring plate 43, and the upper arc plate 44 are all detachable, so that the internal locking frame 12, the cutter head 13, and the filter screen 15 can be installed and removed normally). The high-pressure water flow impacts the fan blade 41, and the fan blade 41 drives the ring sleeve 39 to rotate on the first circular plate 35. The rotation of the ring sleeve 39 drives the ring tooth plate 40 to rotate. The rotation of the ring tooth plate 40 drives the first bevel gear 42 to rotate. The rotation of the first bevel gear 42 drives the second shaft 37 to rotate. The rotation of the second shaft 37 drives the adapter 38 to rotate. The rotation of the adapter 38 drives the cutter head 13 to rotate at high speed between the locking frame 12 and the filter screen 15, thereby changing the position of the cutter head 13 and preventing the cutter head 13 from blocking the water flow from impacting the locking frame 12, thus avoiding dead corners in the cleaning process.

[0037] This invention utilizes the high-speed water flow discharged through the water outlet 45 in the center of the cavity formed by the inverted arc plate 18, the vertical ring plate 43, and the upper arc plate 44 to drive the cutter head 13 to rotate at high speed between the locking frame 12 and the filter screen 15. This changes the position of the cutter head 13, preventing it from blocking the water flow and impacting parts of the locking frame 12, thus avoiding cleaning dead corners. Secondly, it prevents the cutter head 13 from being in contact with the filter screen 15 for a long time, which would cause vibration due to water flow impact, resulting in collision between the cutter head 13 and the filter screen 15, leading to damage to the cutter head 13 and a reduced lifespan.

[0038] As a further aspect of the present invention, friction-reducing materials are used on the contact surfaces of the first sector plate 30 and the second sector plate 31 to reduce equipment friction and extend the service life of the equipment.
