Description

A self-service government service machine with automatic dust removal Technical Field

[0001] This invention relates to the technical field of cleaning government self-service machines, and in particular to an automatic dust-removing government self-service machine. Background Technology

[0002] Government self-service machines refer to devices placed in densely populated places such as community service stations, shopping malls, train stations, large factories, and enterprises to provide users with convenient government self-service.

[0003] Existing self-service government kiosks consist of a base and a terminal unit mounted on the base, with a touchscreen on the terminal unit. When people need to conduct self-service transactions, they can do so by tapping the touchscreen. However, during use, the touchscreen accumulates a significant amount of dust, requiring staff to clean it daily, thus increasing their workload. Summary of the Invention

[0004] To address the issue of staff needing to wipe and clean the touchscreens of government service self-service machines daily, thus increasing their workload, this application provides an automatic dust-cleaning government service self-service machine.

[0005] The self-service government service machine with automatic dust removal provided in this application adopts the following technical solution:

[0006] An automatic dust-cleaning self-service government service machine includes a base, a terminal body mounted on the base, a touch screen mounted on the terminal body, two guide rails mounted on the terminal body, the two guide rails being located on opposite sides of the touch screen, sliders slidably mounted on the guide rails, a connecting rod between the two sliders, a scraper mounted on the connecting rod, a driving mechanism mounted on the guide rails for driving the sliders to move along the length of the guide rails, and a water spraying mechanism mounted on the terminal body for spraying water onto the surface of the touch screen.

[0007] By adopting the above technical solution, a large amount of dust will accumulate on the touch screen of the government self-service machine during long-term use. When it is necessary to clean the touch screen, water is sprayed onto the touch screen through a water spraying mechanism. Then, the drive mechanism drives the slider to move along the length of the guide rail. The slider drives the connecting rod to move along the length of the guide rail, so that the connecting rod drives the scraper to scrape off the dust on the surface of the touch screen. This reduces the need for staff to wipe and clean the touch screen of the government self-service machine every day, thereby reducing the workload of the staff.

[0008] Preferably, the driving mechanism includes a reciprocating screw 1 rotatably disposed within the guide rail, the reciprocating screw 1 passing through the slider, the slider being threadedly connected to the reciprocating screw 1, and a motor being disposed at the top end of each of the two guide rails, the output shaft of the motor being fixedly connected to one end of the reciprocating screw 1.

[0009] By adopting the above technical solution, the motor is started, and the output shaft of the motor drives the reciprocating screw to rotate. The reciprocating screw drives the slider to move along the axial direction of the reciprocating screw, thereby causing the slider to drive the connecting rod to move along the length direction of the guide rail.

[0010] Preferably, one end of the connecting rod passes through one of the sliders, a rack is provided on the terminal body, the rack is close to the bottom of the touch screen, a gear is provided on the connecting rod, the gear is slidably connected to the connecting rod along the axial direction of the connecting rod, the gear can mesh with the rack, and a driving member is provided on the slider for driving the gear to disengage from the rack.

[0011] By adopting the above technical solution, when the motor starts, it drives the reciprocating screw to rotate, causing the reciprocating screw to drive the slider to move towards the bottom of the touch screen. When the slider drives the connecting rod to the bottom of the touch screen, the gear on the connecting rod meshes with the rack, causing the gear to drive the connecting rod to rotate. The connecting rod then drives the scraper to rotate, causing the end face of the scraper away from the connecting rod to move below the connecting rod. Then, the gear disengages from the rack, and the driving component drives the gear to move to one side of the rack. This makes it easier for the end face of the scraper away from the connecting rod to be below the connecting rod when the reciprocating screw drives the slider to move towards the top of the touch screen, reducing the friction between the scraper and the touch screen surface, and thus facilitating the movement of the connecting rod towards the top of the touch screen.

[0012] Preferably, the driving component includes a push rod slidably disposed on the slider, a locking block is engaged on the gear, the end of the push rod away from the slider is fixedly connected to the locking block, a guide rod is fixed on the push rod, a guide plate is disposed on one of the guide rails, the guide plate is located on the side of the rack near the bottom end of the touch screen, a guide groove is formed on the side of the guide plate near the connecting rod, an inclined surface is formed on the inner side of the guide groove near the touch screen, and the outer peripheral surface of the guide rod can abut against the inclined surface.

[0013] By adopting the above technical solution, when the gear disengages from rack one, the connecting rod continues to move towards the bottom of the touch screen, causing the guide rod to abut against the inclined plane one. The inclined plane one pushes the guide rod to move away from the slider, and the guide rod drives the locking block to move away from the slider, causing the locking block to push the gear to move away from the slider, so that the gear moves to one side of the rack. This makes it easier for the reciprocating screw one to drive the slider to move the connecting rod towards the top of the touch screen, and the side of the scraper away from the connecting rod is located below the connecting rod.

[0014] Preferably, the terminal body is provided with a rack two, the gear can mesh with the rack two, the rack two is close to the top of the touch screen, the guide rail is fixed with a guide plate two, the guide plate two is located on the side of the gear two away from the gear one, the guide plate two is provided with a guide groove two on the side of the guide plate two close to the guide plate one, the guide groove two is provided with an inclined surface two on the inner side of the guide groove two away from the touch screen, and the outer peripheral surface of the guide rod can abut against the inclined surface two.

[0015] By adopting the above technical solution, when the reciprocating screw drives the slider to move the connecting rod toward the top of the touch screen, the gear and rack mesh, causing the gear to drive the connecting rod to rotate. The connecting rod then drives the scraper to rotate, moving the scraper away from the end face of the connecting rod and above it. The connecting rod continues to move toward the top of the touch screen, causing the guide rod to abut against the inclined plane. The inclined plane pushes the guide rod toward the direction closer to the slider. The guide rod drives the locking block toward the direction closer to the slider, causing the locking block to drive the gear to move to one side of the rack, so that the gear corresponds to the rack. This facilitates the reciprocating screw driving the slider to move the connecting rod toward the bottom of the touch screen, allowing the scraper to scrape off the dust on the touch screen.

[0016] Preferably, the water spraying mechanism includes a water spray pipe disposed on the terminal body, the water spray pipe being located above the touch screen, a water tank disposed on the terminal body, a water pump disposed on the water tank, a water inlet disposed on the water pump, a water suction pipe disposed on the water pump, the end of the water suction pipe away from the water pump being inserted into the water tank, and an outlet pipe disposed on the water pump, the outlet pipe being connected to one end of the water spray pipe.

[0017] By adopting the above technical solution, the water pump is started, and water in the water tank is pumped into the water pump through the water pump pipe. Then, the water is delivered to the water spray pipe through the water outlet pipe, so that the water spray pipe sprays water onto the surface of the touch screen to clean the surface of the touch screen.

[0018] Preferably, the terminal body is provided with a water receiving trough, which is located at the bottom of the touch screen. Water outlet holes are opened on both sides of the water receiving trough, and drain pipes are fixed on both sides of the water receiving trough. The two drain pipes are respectively connected to the two water outlet holes, and the end of the drain pipe away from the water receiving trough is connected to the outer peripheral surface of the water tank.

[0019] By adopting the above technical solution, when the water spray pipe sprays water onto the surface of the touch screen, the reciprocating screw drives the connecting rod towards the bottom of the touch screen, causing the scraper to scrape the water off the surface of the touch screen and let the water flow into the water collection tank. The water then flows into the water tank through the water outlet and drain pipe, thus facilitating water recycling.

[0020] Preferably, a second reciprocating screw is rotatably mounted between the opposite inner surfaces of the water receiving tank. A push plate is provided on the second reciprocating screw, and the outer surface of the push plate is in contact with the inner surface of the water receiving tank. A drive assembly for driving the second reciprocating screw is provided on the first reciprocating screw.

[0021] By adopting the above technical solution, when water flows into the water receiving tank, the reciprocating screw one drives the drive component two to rotate, and the drive component two drives the reciprocating screw two to rotate, so that the reciprocating screw two drives the push plate to move along the axial direction of the reciprocating screw two, thereby pushing the water in the water receiving tank to both ends of the water receiving tank, so that the water in the water receiving tank can flow into the water tank through the water outlet and drain pipe.

[0022] Preferably, the drive assembly includes a bevel gear one disposed on the reciprocating lead screw one, and a bevel gear two disposed on the reciprocating lead screw two, wherein the bevel gear one meshes with the bevel gear two.

[0023] By adopting the above technical solution, when the reciprocating screw rotates, the reciprocating screw drives the bevel gear to rotate, the bevel gear drives the bevel gear to rotate, and thus the bevel gear drives the reciprocating screw to rotate.

[0024] Preferably, sliding blocks are fixed on both sides of the push plate, and sliding grooves are provided on the opposite inner sides of the water receiving tank, with the sliding blocks slidably disposed in the sliding grooves.

[0025] By adopting the above technical solution, when the push plate moves along the axial direction of the reciprocating screw two, the push plate drives the sliding block to move in the sliding groove, thereby making the push plate move more stably along the axial direction of the reciprocating screw two.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. During prolonged use, the touchscreens of government self-service machines accumulate a large amount of dust. When cleaning is required, a water spraying mechanism sprays water onto the touchscreen, and then a drive mechanism moves a slider along the length of the guide rail. The slider then moves a connecting rod along the length of the guide rail, causing the connecting rod to drive a scraper to remove the dust from the touchscreen surface. This reduces the need for staff to wipe and clean the touchscreens daily, thus reducing their workload.

[0028] 2. Start the motor. The output shaft of the motor drives the reciprocating screw to rotate. The reciprocating screw drives the slider to move along the axial direction of the reciprocating screw, thereby causing the slider to drive the connecting rod to move along the length of the guide rail.

[0029] 3. When the motor starts, it drives the reciprocating screw to rotate, causing the slider to move towards the bottom of the touchscreen. When the slider moves the connecting rod to the bottom of the touchscreen, the gear on the connecting rod meshes with the rack, causing the gear to rotate the connecting rod. The connecting rod then rotates the scraper, moving the scraper's end face away from the connecting rod to below the connecting rod. Then, the gear disengages from the rack, and the drive unit moves the gear to one side of the rack. This ensures that when the reciprocating screw drives the slider towards the top of the touchscreen, the scraper's end face away from the connecting rod is below the connecting rod, reducing the friction between the scraper and the touchscreen surface, thus facilitating the movement of the connecting rod towards the top of the touchscreen.

[0039] The present application will be further described in detail below with reference to Figures 1-8.

[0040] This application discloses an automatic dust removal self-service government service machine.

[0041] Referring to Figures 1 and 2, an automatic dust-cleaning self-service government service machine includes a base 1 and a terminal body 11 fixed on the base 1. A touchscreen 12 is mounted on the terminal body 11. Two parallel guide rails 13 are fixed on the terminal body 11, located on opposite sides of the touchscreen 12. Sliders 14 are slidably mounted on each guide rail 13, and a connecting rod 15 is rotatably mounted between the two sliders 14. A scraper 16 is fitted and fixed to the outer circumference of the connecting rod 15, with the end of the scraper 16 away from the connecting rod 15 positioned above it. The end of the scraper 16 away from the connecting rod 15 is in contact with the surface of the touchscreen 12. A driving mechanism 2 is provided on the terminal body 11 to drive the sliders 14 to move along the length of the guide rails 13, and a water spraying mechanism 3 is provided on the terminal body 11 to spray water onto the surface of the touchscreen 12.

[0042] Referring to Figures 1 and 2, the drive mechanism 2 includes a reciprocating screw 21 rotatably disposed within a guide rail 13. The reciprocating screw 21 is arranged along the length of the guide rail 13 and passes through a slider 14, with the reciprocating screw 21 threadedly connected to the slider 14. A motor 22 is fixed to the top of the guide rail 13, and the output shaft of the motor 22 is fixedly connected to one end of the reciprocating screw 21.

[0043] When the touch screen 12 needs to be cleaned, water is sprayed onto the surface of the touch screen 12 by the water spraying mechanism 3. Then, two motors 22 are started at the same time. The output shaft of the motor 22 drives the reciprocating screw 21 to rotate. The reciprocating screw 21 drives the slider 14 to move along the axial direction of the reciprocating screw 21. The slider 14 drives the connecting rod 15 to move along the axial direction of the reciprocating screw 21. The connecting rod 15 drives the scraper 16 to move along the axial direction of the reciprocating screw 21, so that the scraper 16 scrapes off the dust on the surface of the touch screen 12.

[0044] Referring to Figures 1 and 3, the water spraying mechanism 3 includes a water spray pipe 31 fixed to the terminal body 11. The water spray pipe 31 is arranged along the width direction of the terminal body 11 and is located above the touch screen 12. A water tank 32 is fixedly fixed to the side wall of the terminal body 11, and the water tank 32 is located on the side of the terminal body 11 away from the touch screen 12. A water pump 33 is fixedly fixed to the side wall of the water tank 32. A water suction pipe 34 is fixedly connected to the inlet of the water pump 33. The end of the water suction pipe 34 away from the water pump 33 passes through the side wall of the water tank 32 and is inserted into the water tank 32. The water suction pipe 34 is fixedly connected to the water tank 32. A water outlet pipe 35 is fixedly connected to the outlet of the water pump 33. The end of the water outlet pipe 35 away from the water pump 33 is fixedly connected to one end of the water spray pipe 31. The water outlet pipe 35 communicates with the water spray pipe 31.

[0045] By starting the water pump 33, the water pump 33 draws water from the water tank 32 into the water pump 33 through the water pump pipe 34, and then delivers the water to the water spray pipe 31 through the water outlet pipe 35. The water is then sprayed onto the surface of the touch screen 12 through the water spray pipe 31, so that when the scraper 16 moves, it can scrape off the dust on the surface of the touch screen 12.

[0046] Referring to Figures 1, 3, and 4, a water receiving trough 4 is fixed on the terminal body 11. The water receiving trough 4 is located at the bottom of the touch screen 12. Water outlet holes 41 are opened on both sides of the water receiving trough 4, and drain pipes 42 are fixed on both sides of the water receiving trough 4. The drain pipes 42 are connected to the water outlet holes 41. The end of the drain pipe 42 away from the water receiving trough 4 passes through the side wall of the water tank 32 and is inserted into the water tank 32. The drain pipe 42 is fixedly connected to the water tank 32. A filter plate 36 is fixed inside the water tank 32. The drain pipe 42 is located above the filter plate 36, and the water pumping pipe 34 is located below the filter plate 36.

[0047] Referring to Figures 1, 4, and 5, a reciprocating screw 2 43 is rotatably mounted between the opposite inner surfaces of the water receiving tank 4. A push plate 44 is sleeved on the reciprocating screw 2 43 and threadedly connected to it. The outer surface of the push plate 44 is in contact with the inner surface of the water receiving tank 4. Sliding blocks 45 are fixed on both sides of the push plate 44, and sliding grooves 46 are formed on the opposite inner surfaces of the water receiving tank 4. The sliding blocks 45 are slidably disposed within the sliding grooves 46. The bottom end of one of the reciprocating screws 1 21 passes through the bottom surface of the guide rail 13, and one end of the reciprocating screw 2 43 passes through the end face of the water receiving tank 4. A bevel gear 1 47 is fixed to the bottom end of the reciprocating screw 1 21, and a bevel gear 2 48 is fixed to one end of the reciprocating screw 2 43. The bevel gear 1 47 and the bevel gear 2 48 mesh with each other.

[0048] When the reciprocating screw 21 rotates, it drives the bevel gear 47 to rotate, which in turn drives the bevel gear 48 to rotate. The bevel gear 48 then drives the reciprocating screw 43 to rotate, which in turn drives the push plate 44 to move along the axial direction of the reciprocating screw 43. This push plate 44 pushes the water in the water receiving tank 4 to both ends of the water receiving tank 4, thus facilitating the flow of water in the water receiving tank 4 into the water tank 32 through the water outlet 41 and the drain pipe 42.

[0049] Referring to Figures 6 and 7, one end of the connecting rod 15 passes through the slider 14, and a gear 5 is fitted onto the end of the connecting rod 15 away from the slider 14. Two moving blocks 51 are fixed to the inner circumferential surface of the gear 5, and the two moving blocks 51 are symmetrically arranged along the central axis of the gear 5. Two moving grooves 52 are formed on the outer circumferential surface of the connecting rod 15, and the moving blocks 51 are slidably disposed in the moving grooves 52. The moving blocks 51 are slidably connected to the connecting rod 15 along the axial direction of the connecting rod 15 through the moving grooves 52.

[0050] Referring to Figures 1, 7, and 8, a rack 63 is fixed on the terminal body 11. The rack 63 is located on the side of the guide rail 13 away from the touch screen 12, and the gear 5 can mesh with the rack 63. A wedge-shaped groove 53 is formed on the top surface of one of the sliders 14. A wedge block 54 is slidably disposed in the wedge groove 53. A push block 58 is fixed on the top surface of the wedge block 54. A push rod 55 is fixed on the side of the push block 58 near the gear 5. A locking block 56 is engaged on the gear 5. The end face of the push rod 55 away from the push block 58 is fixedly connected to the side of the locking block 56. A guide rod 57 is fixed on the outer peripheral surface of the push rod 55. A guide plate 6 is fixed on the top surface of one of the guide rails 13. The guide plate 6 is located at the bottom end of the guide rail 13. A guide groove 61 is formed on the side of the guide plate 6 near the connecting rod 15. An inclined surface 62 is formed on the inner side of the guide groove 61 near the touch screen 12. The guide rod 57 can abut against the inclined surface 62.

[0051] When motor 22 is started, its output shaft drives reciprocating screw 21 to rotate. Screw 21 drives slider 14, which in turn moves connecting rod 15 towards the bottom of touchscreen 12. When connecting rod 15 reaches the bottom of touchscreen 12, gear 5 meshes with rack 63. Gear 5 drives connecting rod 15 to rotate, causing scraper 16 to rotate and move away from the side of connecting rod 15 until it is below it. Then, gear 5 disengages from rack 63, and connecting rod 15 continues to move downwards. The guide rod 57 abuts against the inclined plane 62, and the inclined plane 62 pushes the guide rod 57 to move away from the slider 14. The guide rod 57 drives the push rod 55 to move, and the push rod 55 drives the locking block 56 to move. The locking block 56 pushes the gear 5 to move, and the gear 5 moves to one side of the rack 63. This reduces the friction between the scraper 16 and the surface of the touch screen 12 when the reciprocating screw 21 drives the connecting rod 15 to move towards the top of the touch screen 12, thereby facilitating the connecting rod 15 to drive the scraper 16 to move upward.

[0052] Referring to Figures 1, 7, and 8, a rack 2 73 is provided on the terminal body 11. The rack 2 73 is located near the top of the guide rail 13, and the gear 5 can mesh with the rack 2 73. A guide plate 2 7 is fixed on the guide rail 13. Both the guide plate 2 7 and the guide plate 1 6 are L-shaped plates. The guide plate 2 7 and the guide plate 1 6 are both on the same guide rail 13, with the guide plate 2 7 located at the top of the guide rail 13. The rack 1 63 and the rack 2 73 are located between the guide plate 1 6 and the guide plate 2 7, respectively. A guide groove 2 71 is formed on the side of the guide plate 2 7 near the guide plate 1 6. An inclined surface 2 72 is formed on the inner side of the guide groove 2 71 away from the touch screen 12, and the guide rod 57 can abut against the inclined surface 2 72.

[0053] When the reciprocating screw 21 drives the connecting rod 15 to move the scraper 16 upward, the gear 5 meshes with the rack 73. The gear 5 drives the connecting rod 15 to rotate, causing the connecting rod 15 to drive the scraper 16 to rotate. This causes the scraper 16 to rotate away from the end face of the connecting rod 15 and move above the connecting rod 15, so that the end of the scraper 16 away from the connecting rod 15 is in contact with the surface of the touch screen 12. This makes it easier for the connecting rod 15 to drive the scraper 16 to move towards the bottom of the touch screen 12, so that the scraper 16 can scrape off the dust on the touch screen 12. The connecting rod 15 continues to move toward the top of the touch screen 12. The guide rod 57 abuts against the inclined plane 72. The inclined plane 72 pushes the guide rod 57 toward the direction closer to the slider 14. The guide rod 57 drives the push rod 55 to move toward the direction closer to the slider 14, so that the push rod 55 drives the locking block 56 to move toward the direction closer to the slider 14. The locking block 56 drives the gear 5 to move toward the direction closer to the slider 14, so that the gear 5 moves to the side of the rack 73 close to the slider 14 and is opposite to the rack 63. This makes it easier for the gear 5 to mesh with the rack 63 when the reciprocating screw drives the connecting rod 15 toward the bottom of the touch screen 12.

[0054] The implementation principle of an automatic dust-removing self-service government service machine according to an embodiment of this application is as follows: When it is necessary to clean the touch screen 12 of the self-service government service machine, the water pump 33 is started. The water pump 33 draws water from the water tank 32 into the water pump 33 through the water pipe 34, and then delivers the water to the spray pipe 31 through the water outlet pipe 35. The water is then sprayed onto the surface of the touch screen 12 through the spray pipe 31. At the same time, two motors 22 are started. The output shaft of the motor 22 drives the reciprocating screw 21 to rotate. The reciprocating screw 21 drives the slider 14 to move the connecting rod 15 along the length direction of the guide rail 13. The connecting rod 15 drives the scraper 16 to move along the length direction of the guide rail 13, thereby scraping off the dust on the surface of the touch screen 12, reducing the need for staff to clean the touch screen 12 of the self-service government service machine, and thus reducing the workload of the staff.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
