Technical Field

[0001] The present invention relates to an intelligent disinfector for subway handrails, which belongs to the field of traffic sanitation equipment, and more particularly to an intelligent disinfector for subway handrails that can automatically disinfect handrails in all directions through motion sensing. Background Art

[0002] The disinfection of the announcement area has gradually become a new focus, especially for the handrails on subways and buses. Due to the high frequency of being touched every day, they are very likely to become a place for viruses to stay and a medium for transmission. The traditional disinfection method is manual disinfection and cleaning, which is labor-intensive and frequent, and has low cleaning efficiency. In addition, subways and trains will be suspended during disinfection and cleaning, affecting their normal departure time. The existing devices for disinfecting handrails mostly change the structure of the handrail itself so that it can be disinfected independently.

The cross-sectional area of ​​the bottom of the disinfectant box (7) gradually decreases from top to bottom. Control boxes (10) are arranged on both sides of the main body box (11). Drive pumps (9) are arranged on both sides of the main body box (11). One end of two hoses (8) are respectively connected to the liquid inlets of the two drive pumps (9). The hoses (8) are connected to the drive pumps (9). The other end of the hoses (8) is connected to the bottom of the disinfectant box (7). The hoses (8) are connected to the interior of the disinfectant box (7). The disinfection nozzle (14) is connected to the liquid outlets of the two driving pumps (9) through connecting pipes and is in communication with each other. The disinfection nozzle (14) is located in the main body box (11). The two guide rods (12) are respectively placed on both sides of the main body box (11). The two guide rods (12) are symmetrical in center. The ends of the two guide rods (12) are bent and extended in opposite directions. A plurality of ultraviolet lamps (13) are respectively arranged at equal distances on the inner walls of both sides of the main body box (11). Two groups of baffles (15) are respectively placed in the main body box (11) near both sides. Each group of baffles (15) is composed of a plurality of baffles (15) arranged at equal distances. The control box (10) has a built-in battery. The control box (10) has a built-in infrared sensor. The control box (10) has a built-in control panel. A signal converter, a data processor and a controller are arranged on the control panel. The signal converter is connected to the infrared sensor signal via a data transmission line. The data processor is connected to the signal converter signal via a data transmission line. The controller is connected to the data processor, the ultraviolet lamp (13) and the driving pump (9) via the data transmission line. The battery is electrically connected to the data processor, the ultraviolet lamp (13) and the driving pump (9) via a power line. The end of the guide rod (12) is made of rubber material. The two connecting plates (5) are respectively connected to the sliding sleeve (4). The disinfectant tank (7) is connected to the main body box (11). A sealing ring is disposed at the top edge of the disinfectant tank (7) and the bottom edge of the main body box (11).

[0024] The signal converter is capable of receiving the infrared wavelength signal of the infrared sensor and performing signal conversion;

[0025] The data processor and the signal converter perform information exchange, and a computer program is stored in the data processor, and the following steps are implemented when the program is executed:

[0026] Receive the infrared wavelength signal transmitted by the signal converter, perform data processing, obtain the currently sensed infrared wavelength, and compare the processed infrared wavelength value with the preset value in the data processor;

[0027] The controller and the data processor exchange information and execute instructions issued by the data processor, thereby starting the drive pump (9) and turning on the ultraviolet lamp (13);

[0028] The battery provides power for the UV lamp (13), the drive pump (9), and the battery may include a power management system, one or at least two power supplies, and other components associated with generating, managing and distributing power to the data processing device.

[0029] When in use, firstly, two lead screws (1) are arranged on the carriage so that the two lead screws (1) are placed across the crossbar (2) of the handrail (3), and the two lead screws (1) are respectively connected to the motor shafts of two drive motors. When the handrail (3) needs to be disinfected, the drive motor is started, and the motor shaft of the drive motor drives the lead screw (1) to rotate, so that the sliding sleeve (4) can move along the lead screw (1), and the main body box (11) moves with the movement of the sliding sleeve (4). When the main body box (11) moves close to the handrail (3), the guide rod (12) on one side of the main body box (11) first touches the handrail (3) and pushes the handrail (3) to deflect, and then as the main body box (11) continues to move forward, the handrail (3) can gradually enter the main body box (11). At this time, after the infrared sensor in the control box (10) senses the handrail (3), it can transmit the sensed infrared wavelength data to the signal converter, and the signal converter converts the data and transmits it to the data processor. The data processor determines that when the value exceeds the preset value, the data processor controls the ultraviolet lamp (13) to turn on through the controller, and at the same time controls the drive pump (9) to start. After the drive pump (9) is started, the disinfectant in the disinfectant tank (7) can be drawn and sprayed onto the handrail (3) through the disinfectant nozzle (14), thereby disinfecting the handrail (3). In combination with the ultraviolet light radiation, automatic double disinfection of the handrail (3) is achieved. The disinfectant sprayed onto the handrail (3) can gradually accumulate and then drip into the disinfectant tank (7) for reuse.

[0030] The design of the stiffening rib (6) can increase the stability of the connection between the connecting plate (5) and the main box (11), and the main box (11) will not fall off when moving with the connecting plate (5);

[0031] The design of the end of the guide rod (12) being made of rubber material can, on the one hand, protect the guide rod (12) and the handrail (3) to avoid rigid contact between the guide rod (12) and the handrail (3); on the other hand, it can prevent the handrail (3) from touching the hand of a person holding the handrail (3) in front during mobile disinfection, thereby causing accidental injury;

[0032] The ends of the two guide rods (12) are respectively bent and extended in opposite directions, so that the rotation of the armrest (3) can be guided by the curvature of the bend, thereby ensuring that the armrest (3) can smoothly enter the main box (11) for all-round disinfection;

[0033] The cross-sectional area of ​​the bottom of the main box (11) gradually decreases from top to bottom. When the disinfectant is sprayed for disinfection, the sprayed disinfectant can gradually gather and drip into the main box (11) after disinfection, and then slide along the inner wall of the main box (11) to the bottom of the main box (11), and then slide into the disinfectant box (7), which is conducive to the recycling of the disinfectant;

[0034] The cross-sectional area of ​​the bottom of the disinfectant tank (7) gradually decreases from top to bottom. When the disinfectant is extracted, after the disinfectant at the bottom is extracted, the subsequent disinfectant can quickly slide to the bottom for timely replenishment, thereby improving the utilization efficiency of the disinfectant in the disinfectant tank (7);

[0035] The design in which the two connecting plates (5) are respectively engaged with the sliding sleeves (4) makes it easy to remove the main box (11) through the connecting plates (5) for maintenance;

[0036] The design of the disinfectant box (7) and the main box (11) being snap-fitted together makes it easy to remove the disinfectant and replace it;

[0037] The top edge of the disinfectant box (7) and the bottom edge of the main box (11) are provided with sealing rings, which can ensure the sealing between the disinfectant box (7) and the main box (11) and prevent the disinfectant from overflowing from the connection between the disinfectant box (7) and the main box (11);

[0038] The ultraviolet lamp (13) is designed in conjunction with the disinfection nozzle (14) to perform double all-round disinfection on the handrail (3), thereby ensuring the disinfection effect on the handrail (3);

[0039] The guide rod (12) cooperates with the design of the main box (11), and when performing mobile disinfection, the guide rod (12) can be used to first drive the handrail (3) to rotate, and the handrail (3) can be limited and guided so that the handrail (3) can smoothly enter the main box (11) for all-round disinfection;

[0040] The purpose of automatically disinfecting the handrail (3) in all directions through motion sensing is achieved.

[0041] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any person skilled in the art may make some improvements without departing from the scope of the present invention, that is, any equivalent improvements made according to the present invention should be covered by the scope of the present invention.
