Description

Technical Field

[0001] This utility model relates to the technical field of elevator car disinfection equipment, and in particular to an elevator car cleaning device. Background Technology

[0002] In residential buildings, commercial buildings, hospitals, factories, and other places, people use elevator cars to move conveniently between different floors. For example, in high-rise residential buildings, residents rely on elevator cars to go up and down floors, avoiding the inconvenience of climbing stairs. In shopping malls, customers can easily reach different shopping floors using elevator cars.

[0003] As mentioned above, people going up and down stairs are highly likely to use elevator cars. An elevator car is a relatively enclosed space with relatively poor air circulation. When a passenger carrying a virus (such as SARS or influenza) enters the car, the virus may remain suspended in the air for a period of time. Furthermore, frequent entry and exit of people, and close contact between different individuals within the car, increase the risk of virus transmission.

[0004] To address the aforementioned issues, cleaning staff are typically assigned to clean and disinfect elevator cars. Furthermore, to improve cleaning efficiency and avoid prolonged cleaning and disinfection time in the elevator car, elevator car cleaning equipment has emerged on the market. For example, a Chinese patent with publication number CN115870248B discloses an elevator car cleaning device, which includes a base and a support frame. The support frame is welded to the upper end of the base, and a slider is slidably connected inside the support frame. The left and right ends of the slider extend outwards from the left and right ends of the support frame, respectively. A drive shaft extending outwards from the left end of the slider is rotatably connected to the middle of the slider. Inserting and removing blocks adjusts the height of the T-shaped handrail. When using this equipment, cleaning staff push the T-shaped handrail to move the device, pull down the stabilizing suction cup to securely place the device inside the elevator car, motor one adjusts the height of the cleaning roller, motor three adjusts the angle of the cleaning roller, motor two rotates the cleaning roller, and motor four rotates the cleaning roller. An external water source is connected to the connector to allow an electric spray nozzle to spray water onto the cleaning roller.

[0005] While the equipment provided by the aforementioned patent can assist cleaning staff in efficiently completing disinfection and cleaning processes, solving the problems of low efficiency, high labor intensity, and time-consuming and laborious cleaning of existing elevator cars, it still has some drawbacks. For example, it cannot promptly clean and disinfect the elevator car. Because the number of cleaning staff is limited, and each cleaner has to undertake a large number of cleaning tasks, it means that the cleaning staff cannot perform timely cleaning and disinfection of the elevator car.

[0006] Elevator buttons are a part that passengers must touch. Whether entering the elevator to select a floor or pressing the open / close button to exit, almost everyone who uses the elevator touches the buttons. This makes the button area a high-risk area for virus transmission. For example, during the peak of the pandemic, numerous studies found various viruses and bacteria on elevator buttons. As mentioned in the previous paragraph, if the elevator car (especially the buttons) is not disinfected and cleaned in a timely manner, it can easily lead to cluster infections.

[0050] like Figure 10 As shown, in order to disinfect and clean the button area of ​​the elevator car 7 in a timely manner and change the method of waiting for manual disinfection and cleaning, this embodiment provides a disinfection and cleaning device for the button area of ​​the elevator car 7.

[0051] like Figure 1 , Figure 6As shown, the disinfection and cleaning device specifically includes a disinfection device 4, a connecting frame 6, a support frame 1, connecting devices 5, and a drive mechanism 2. Two sets of connecting devices 5 are provided, respectively located at both ends of the support frame 1. Therefore, under the action of the connecting devices 5, the support frame 1 can be stably installed on the side of the button area, for example, ensuring the support frame 1 is stably placed vertically. Before the support frame 1 is stably installed on the side of the elevator car 7, one end of the connecting frame 6 is fitted onto the support frame 1. Therefore, with the support frame 1 stably installed, the connecting frame 6 is also stably installed, providing support for the connecting frame 6 to move along the length of the support frame 1 under external force. After both the support frame 1 and the connecting frame 6 are stably installed, the disinfection device 4 is stably installed on the end of the connecting frame 6 away from the support frame 1, directly opposite the side of the button. To control the reciprocating movement of the disinfection device 4 along the length of the buttons and achieve comprehensive disinfection, a drive mechanism 2 is installed on the side of the support frame 1 and connected to the connecting frame 6. Therefore, when the drive mechanism 2 is working, the connecting frame 6 can be controlled to move the disinfection device 4, providing support for the reciprocating movement of the disinfection device 4 and achieving comprehensive disinfection and cleaning of the buttons. A control box 3 is also provided at the end of the support frame 1. The power cord of the control box 3 is connected to the power supply of the elevator car 7, thereby providing power for the drive mechanism 2 and the disinfection device 4.

[0052] like Figure 7 , Figure 8 As shown, in order to disinfect the buttons using the disinfection device 4, the disinfection device 4 is configured as an ultraviolet disinfection lamp, which includes an ultraviolet disinfection lamp rod 43, a cover 44, a ballast, and a lamp holder. The lamp holder is installed at both ends of the cover 44 and is electrically connected to the ultraviolet disinfection lamp rod 43. The ballast is also electrically connected to the ultraviolet disinfection lamp rod 43. The cover 44 is located on the side of the ultraviolet disinfection lamp rod 43 away from the button area and covers the ultraviolet disinfection lamp rod 43. Furthermore, the central angle of the cover 44 is greater than or equal to 180°. Therefore, under the action of the cover 44, the propagation of ultraviolet light can be blocked, the propagation range of ultraviolet light can be limited, and damage to personnel inside the elevator car 7 caused by the operation of the ultraviolet disinfection lamp rod 43 can be avoided.

[0053] like Figure 3 , Figure 9As shown, to ensure stable installation of the disinfection device 4, the connecting frame 6 includes a plate 61 and two tubes 62. The two tubes 62 are arranged in parallel and perpendicularly to the same end of the plate 61. Additionally, the support frame 1 includes two parallel guide rods 11 and two sets of clamps 14. The two sets of clamps 14 are detachably mounted on both ends of the two guide rods 11 and are respectively fitted onto two sets of connecting devices 5. Thus, under the action of the two connecting devices 5, the two guide rods 11 are stably installed on the elevator car 7. Before installing the guide rods 11, they are installed through the tubes 62. Therefore, with the cooperation of the two guide rods 11 and the two tubes 62, the connecting frame 6 can be stably installed on the side of the support frame 1, thereby ensuring stable installation of the disinfection device 4.

[0054] like Figure 5 , Figure 9 As shown, to control the disinfection device 4 to move along the length of the guide rod 11, the drive mechanism 2 includes a motor 23, a first wheel 22, a second wheel 24, and a pull rope 21. The second wheel 24 is sleeved on the power output shaft of the motor 23. The motor 23 is mounted on the side of a clamp 14 via a frame. The central shaft of the first wheel 22 is mounted on the side of another clamp 14 via another frame. The pull rope 21 is designed as a loop structure; therefore, both ends of the pull rope 21 are sleeved on the first wheel 22 and the second wheel 24 respectively, and the pull rope 21 is taut. The pull rope 21 can be replaced with a synchronous belt, and the wheel 24 can be replaced with a synchronous pulley. The motor 23 can be a servo motor, a stepper motor, etc.

[0055] like Figure 9 As shown, the connecting frame 6 also includes a second arc-shaped plate 64, which is mounted on a certain tube 62, and a clamping arc plate 65 is bolted to its side. One side of the annular pull rope 21 passes through the space formed by the clamping arc plate 65 and the second arc-shaped plate 64, realizing a fixed connection between the plate 61 and one side of the pull rope 21. Therefore, when the motor 23 is working, the pull rope 21 can be rotated under the action of the wheel, thereby controlling the plate 61 to drive the disinfection device 4 to move back and forth along the length of the guide rod 11, realizing comprehensive disinfection of the button.

[0056] like Figure 9 As shown, the connecting frame 6 also includes a first arc plate 63. The central angle of the first arc plate 63 is greater than 180°, and the first arc plate 63 is installed on another tube 62. At the same time, one side of the annular pull rope 21 passes through the first arc plate 63. Since the inner diameter of the first arc plate 63 is larger than the diameter of the pull rope 21, the presence of the first arc plate 63 serves to restrict the pull rope 21.

[0057] To control the operation of motor 23 and disinfection device 4, control box 3 is equipped with contactors, relays, controllers (such as PLCs), and power modules. The power lines of motor 23 and disinfection device 4 are connected to the corresponding terminals in the control box, and signal lines are also connected inside. This provides power to motor 23 and disinfection device 4, enabling their operation and facilitating the periodic disinfection of the button area. Additionally, a timer can be equipped for disinfection device 4 to control the operating time of the ultraviolet disinfection lamp. Alternatively, the signal lines of the button panel inside the elevator car can be connected to the controller in the control box. When no one presses a button, the controller can activate the motor and ultraviolet disinfection lamp to disinfect and clean the buttons. Since motor 23, ultraviolet disinfection lamp, electrical control box, and elevator car are all existing technologies, this is only a brief introduction.

[0058] like Figure 7 , Figure 9 As shown, to ensure a stable connection between the disinfection device 4 and the connecting frame 6, and to allow for adjustment of the state of the disinfection device 4 as needed, a through hole is provided at the end of the plate 61 away from the tube 62. A back rod 41 is provided on the back side of the disinfection device 4, and a stud 42 is fixedly installed in the middle of the back rod 41. The stud 42 passes through the through hole of the plate 61, and a nut is threaded onto the end of the stud 42. Therefore, under the action of the nut, the interaction force between the plate 61 and the back rod 41 can be increased, thereby making the back rod 41 stably placed relative to the plate 61. In addition, due to the presence of the nut, the constraint between the back rod 41 and the plate 61 can be released by rotating the nut, and the state of the disinfection device 4 can be adjusted to fit the width of the button area.

[0059] like Figure 3 As shown, in order to make the clamp 14 and the guide rod 11 stably and detachably connected, a threaded groove 12 is provided at the end of the guide rod 11, and a bracket is provided on the side of each clamp 14. A countersunk hole 15 is provided on the bracket, and a connecting bolt 13 is provided through the countersunk hole 15. The end of the connecting bolt 13 is threaded into the threaded groove 12. Therefore, under the action of the connecting bolt 13, a stable connection between the clamp 14 and the guide rod 11 is achieved.

[0060] like Figure 4As shown, to ensure the clamp 14 is stably installed on the side of the elevator car 7, the connecting device 5 includes a cylinder 51 and a piston 52. An internally threaded pipe is fixedly installed at the closed end of the cylinder 51, and a sealing layer is provided at the open end of the cylinder 51. The piston 52 is located inside the cylinder 51, and a sealing layer is provided on the side of the piston 52 that contacts the cylinder 51. A threaded rod 53 is provided on the side of the piston 52, with its threads penetrating the internally threaded pipe. When the open end of the cylinder 51 is placed against the side wall of the elevator car 7, the piston 52 can be moved by rotating the threaded rod 53, increasing the space formed by the cylinder 51, piston 52, and side wall of the elevator car 7, reducing the air pressure in this space, and utilizing the pressure difference between the inside and outside, ensuring the cylinder 51 is stably fitted against the side of the elevator car 7. The clamp 14 is sleeved on the internally threaded pipe; therefore, with the cylinder 51 stably installed, the guide rod 11 can be stably installed as well.

[0061] The aforementioned disinfection and cleaning devices can also be installed at the button areas on each floor of the elevator.

[0062] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0063] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
