Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator disinfection and purification device and a control method. Background Art

[0002] Elevators are an indispensable means of transportation in multi-story and high-rise buildings. Due to poor air circulation in the elevator car and direct or indirect contact between elevator users, it is very easy for various bacteria and viruses to breed inside the elevator. In addition, various odors (such as sweat and odor) produced by the human body will also affect the health of users if they are not handled in time. Therefore, it is necessary to regularly carry out effective disinfection (sterilization) and deodorization of elevators.

[0003] Among the existing patents, the patent with publication number CN116370684A proposes a disinfection and deodorization system, a manned elevator system and a control method thereof. When disinfecting the air inside the elevator car, it is necessary to connect to the elevator system, or install a human body sensor to identify whether there is someone, and perform unmanned disinfection. A first disinfection and deodorization device releases disinfection and deodorization substances into the air duct to disinfect and deodorize the gas in the air duct. A catalytic decomposition device is added to disinfect and deodorize the excess ozone in the air duct, and the remaining ozone is catalytically decomposed. A liquid storage container is added to connect to the air duct through an atomization passage. The atomization device atomizes the disinfectant in the liquid storage container, thereby efficiently disinfecting and deodorizing the gas in the air duct. In addition, an identification device, a control device, a temperature detection device, an ozone concentration detection device, etc. are added, and an external power supply is required to power each device, so that multiple devices need to be connected and powered by an external power supply, resulting in a complex structure and troublesome installation. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an elevator disinfection and purification device and a control method to solve the problems raised in the above background technology. The present invention has a reasonable structure, does not need to be connected to the elevator system, or install a human body sensor to identify whether there is someone for unmanned disinfection, and has a simple structure and is easy to install.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: an elevator disinfection and purification device, comprising: An elevator car top and an elevator lighting lamp arranged on the elevator car top, wherein a power supply circuit for supplying power to the elevator lighting lamp is arranged on the elevator car top; wherein, An air purification module for purifying the air in the elevator, a disinfection module for sterilizing the air in the elevator, and a detection and control module are arranged on the top of the elevator car; The detection control module is used to detect the opening and closing of the elevator lighting. When it is detected that the elevator lighting is turned on, the air purification module is controlled to be turned on and the disinfection module is turned off. When it is detected that the elevator lighting is turned off, the air purification module is controlled to be turned off and the disinfection module is turned on.

[0006] Further, the detection control module includes a disinfection controller and a control relay arranged on the top of the elevator car; The control relay is used to detect the opening and closing of the elevator lighting and, when it is detected that the elevator lighting is turned on, sends a signal to the disinfection controller to control the disinfection module to turn off and the air purification module to turn on. When it is detected that the elevator lighting is turned off, it sends a signal to the disinfection controller to control the disinfection module to turn on and the air purification module to turn off.

[0007] Furthermore, the power supply circuit includes two front-end power lines and two rear-end power lines. The two front-end power lines are used to power the disinfection module and the disinfection controller, and the two rear-end power lines are used to power the air purification module, the elevator lighting, and the control relay.

At the same time, the neutral wire is connected to one end of the air purification module and the live wire is connected to the other end of the air purification module through the relay output end of the disinfection controller. The live wire and the neutral wire in the two rear-end power lines are connected to the elevator lighting, and the normally open contact of the control relay is connected to the input detection interface of the disinfection controller.

[0009] Furthermore, the disinfection controller includes a Bluetooth module, a microprocessor controller, a clock chip, a FLASH memory and a relay; The input detection interface of the disinfection controller is connected to the microprocessor controller of the disinfection controller; The Bluetooth module is used to connect and communicate with an external mobile phone or Bluetooth device and send the received current time, disinfection and purification start and end time data to the microprocessor controller of the disinfection controller; The microprocessor controller of the disinfection controller writes the received current time data into the clock chip and stores the disinfection and purification start and end time data into the FLASH memory. The microprocessor controller of the disinfection controller reads the current time data inside the clock chip in real time and compares it with the disinfection and purification start and end time data. When the read current time data is within the range of the disinfection and purification start and end time data, the control relay sends the signal detected when the elevator lighting is turned on to the microprocessor controller of the disinfection controller to control the disinfection module to turn on and the air purification module to turn on, and sends the signal detected when the elevator lighting is turned off to the microprocessor controller of the disinfection controller to control the disinfection module to turn on and the air purification module to turn off.

[0010] Furthermore, the air purification module is a negative oxygen ion generator, and the disinfection module is an ultraviolet lamp.

DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] like Figure 1 As shown, the present invention provides a technical solution: an elevator disinfection and purification device, comprising: The elevator car top 101 and the elevator lighting lamp 107 arranged on the elevator car top 101, the elevator car top 101 is provided with a power supply circuit 109 for supplying power to the elevator lighting lamp 107; wherein, An air purification module 108 for purifying the air in the elevator, a disinfection module 106 for sterilizing the air in the elevator, and a detection control module 1010 are provided on the elevator car top 101; The detection control module 1010 is used to detect the opening and closing of the elevator lighting 107. When it is detected that the elevator lighting 107 is turned on, the air purification module 108 is controlled to be turned on and the disinfection module 106 is controlled to be turned off. When it is detected that the elevator lighting 107 is turned off, the air purification module 108 is controlled to be turned off and the disinfection module 106 is turned on. This design uses the detection control module 1010 to control the air purification module 108 to be turned on and the disinfection module 106 to be turned off when the elevator lighting 107 is turned on. When it is detected that the elevator lighting 107 is turned off, the air purification module 108 is controlled to be turned off and the disinfection module 106 is turned on, thereby facilitating effective safe and harmless disinfection and air purification of the elevator car. There is no need to connect to the elevator system or install a human body sensor to identify whether there is someone for unmanned disinfection. The structure is simple and easy to install.

[0016] The elevator lighting 107 is in a closed state when there is no one in the elevator or when the elevator is out of operation due to timeout, and is in an open state when there is someone in the elevator. This is an energy-saving working mode currently available in all elevators and is the prior art.

[0017] The detection control module 1010 includes a disinfection controller 104 and a control relay 105 disposed on the elevator car top 101; The control relay 105 is used to detect the opening and closing of the elevator lighting 107 and send a signal to the disinfection controller 104 to control the disinfection module 106 to turn off and the air purification module 108 to turn on when the elevator lighting 107 is detected to be turned on. When the elevator lighting 107 is detected to be turned off, a signal is sent to the disinfection controller 104 to control the disinfection module 106 to turn on and the air purification module 108 to turn off. This design sends a signal to the disinfection controller 104 to control the disinfection module 106 to turn off and the air purification module 108 to turn on when the elevator lighting 107 is detected to be turned on. When the elevator lighting 107 is detected to be turned off, a signal is sent to the disinfection controller 104 to control the disinfection module 106 to turn on and the air purification module 108 to turn off. There is no need to access the elevator system or install a human body sensor to identify whether there is someone performing unmanned disinfection. The structure is simple and easy to install.

[0018] The power supply circuit 109 includes two front-end power lines 102 and two rear-end power lines 103. The two front-end power lines 102 are used to power the disinfection module 106 and the disinfection controller 104, and the two rear-end power lines 103 are used to power the air purification module 108, the elevator lighting 107, and the control relay 105. This design facilitates powering the disinfection module 106, the disinfection controller 104, the elevator lighting 107 and the control relay 105.

[0019] The live wires in the two front-end power lines 102 are respectively connected in series with the relay output end of the disinfection controller 104, the normally closed contact 105C of the control relay 105, and one end of the disinfection module 106, and the neutral wires in the two front-end power lines 102 are connected to the other end of the disinfection module 106. The live wires and neutral wires in the two front-end power lines 102 are respectively connected to the power input wire of the disinfection controller 104 to power the disinfection controller 104; The live wire and the neutral wire in the two rear-end power lines 103 are connected to the two ends of the coil 105A in the control relay 105, and the neutral wire is connected to one end of the air purification module 108 and the live wire is connected to the other end of the air purification module 108 through the relay output end of the disinfection controller 104, wherein the relay output end of the disinfection controller 104 here is another, and the disinfection controller 104 has two relay output ends, one of which is connected to the normally closed contact 105C of the control relay 105, and the other is connected to the air purification module 108, the live wire and the neutral wire in the two rear-end power lines 103 are connected to the elevator lighting 107, and the normally closed contact 105C of the control relay 105 is connected to the elevator lighting 107. The open contact 105B is connected to the input detection interface of the disinfection controller 104. This design facilitates the use of two front-end power lines 102 to be electrically connected to the disinfection controller 104, the relay output end of the disinfection controller 104, the normally closed contact 105C of the control relay 105 and the disinfection module 106, thereby facilitating power supply. It is also convenient to use two rear-end power lines 103 to be connected to the coil 105A in the control relay 105, the relay output end of the disinfection controller 104, the air purification module 108 and the elevator lighting 107, thereby facilitating power supply and further realizing control of the air purification module 108 and the disinfection module 106. When the disinfection controller 104 detects that the elevator lighting 107 is turned on, it controls the air purification module 108 to turn on and the disinfection module 106 to turn off. When it detects that the elevator lighting 107 is turned off, it controls the air purification module 108 to turn off and the disinfection module 106 to turn on, thereby achieving effective safe and harmless disinfection and air purification of the elevator car. The disinfection controller 104 detects the opening and closing of the elevator lighting 107 through the coil 105A of the control relay 105 and the normally open contact 105B of the control relay 105. Since the coil 105A of the control relay 105 is connected to the two rear-end power lines 103 and the two rear-end power lines 103 are connected, the two rear-end power lines 103 are connected. 3 is connected to the elevator lighting 107. When the elevator lighting 107 is turned on, the coil 105A of the control relay 105 is energized to close the normally open contact 105B of the control relay 105. Since the normally open contact 105B of the control relay 105 is connected to the input detection interface of the disinfection controller 104, the closure of the normally open contact 105B of the control relay 105 can be detected, so that the turning on of the elevator lighting 107 can be detected. Similarly, when the normally open contact 105B of the control relay 105 is detected to be open, it means that the coil 105A of the control relay 105 is de-energized and the elevator lighting 107 is in the off state.

[0020] The disinfection controller 104 includes a Bluetooth module, a microprocessor controller, a clock chip, a FLASH memory and a relay; The input detection interface of the disinfection controller 104 is connected to the microprocessor controller of the disinfection controller 104; The Bluetooth module is used to connect and communicate with an external mobile phone or Bluetooth device and send the received current time, disinfection and purification start and end time data to the microprocessor controller of the disinfection controller 104, where the current time data here is the current Beijing time data; The microprocessor controller of the disinfection controller 104 writes the received current time data into the clock chip and stores the disinfection and purification start and end time data into the FLASH memory. The microprocessor controller of the disinfection controller 104 reads the current time data inside the clock chip in real time and compares it with the disinfection and purification start and end time data. When the read current time data is within the range of the disinfection and purification start and end time data, the control relay 105 sends the signal detected when the elevator lighting 107 is turned on to the microprocessor controller of the disinfection controller 104 to control the disinfection module 106 to turn off and the air purification module 108 to turn on. The signal detected when the elevator lighting 107 is turned off is sent to the microprocessor controller of the disinfection controller 104 to control the disinfection module 106 to turn on and the air purification module 108 to turn on. 108 is closed. The design can connect and communicate with an external mobile phone or Bluetooth device by using a Bluetooth module, so that the current time can be written into the clock chip through the microprocessor controller of the disinfection controller 104, and the start and end time of disinfection and purification can be set as required through the microprocessor controller of the disinfection controller 104 and stored in the FLASH memory. Then the microprocessor controller of the disinfection controller 104 reads the current time data inside the clock chip in real time and compares it with the start and end time data of disinfection and purification, so that the disinfection module 106 and the air purification module 108 can work within the start and end time of disinfection and purification set according to the requirements. The Bluetooth module is a low-power Bluetooth module that can send its own unique identification code to the surrounding area, so that the mobile phone or Bluetooth device can search and connect through software.

[0021] The air purification module 108 is a negative oxygen ion generator, and the disinfection module 106 is an ultraviolet lamp. This design can achieve effective safe and harmless disinfection and air purification of the elevator car by using the negative oxygen ion generator and the ultraviolet lamp.

[0022] A control method for an elevator disinfection and purification device comprises the following steps: Step A sends the current time, disinfection and purification start and end time data to the Bluetooth module through an external mobile phone or Bluetooth device; Step B: the Bluetooth module sends the received current time, disinfection and purification start and end time data to the microprocessor controller of the disinfection controller 104; Step C: The microprocessor controller of the disinfection controller 104 writes the received current time data into the clock chip and stores the disinfection and purification start and end time data into the FLASH memory; Step D: The microprocessor controller of the disinfection controller 104 reads the current time data inside the clock chip in real time and compares it with the disinfection and purification start and end time data; Step E: When the compared current time data is within the range of the start and end time data of the disinfection and purification, when the control relay 105 detects that the elevator lighting 107 is turned on, a signal is sent to the microprocessor controller of the disinfection controller 104 to respectively control the relay output end of the disinfection controller 104 connected to the normally closed contact 105C of the control relay 105 to cut off the power and the control relay 105 to control its normally closed contact 105C to open to close the disinfection module 106, and control the relay output end of the disinfection controller 104 connected to the other end of the air purification module 108 to power on to control the air purification module 108 to turn on; When it is detected that the elevator lighting 107 is turned off, a signal is sent to the microprocessor controller of the disinfection controller 104 to respectively control the relay output end of the disinfection controller 104 connected to the normally closed contact 105C of the control relay 105 to be energized and the control relay 105 to control its normally closed contact 105C to be closed to open the disinfection module 106, and control the relay output end of the disinfection controller 104 connected to the other end of the air purification module 108 to be de-energized to control the air purification module 108 to be closed; In step F, when the compared current time data is not within the range of the start and end time data of the disinfection and purification, a signal is sent to the microprocessor controller of the disinfection controller 104 to respectively control the power-off of the relay output end of the disinfection controller 104 connected to the normally closed contact 105C of the control relay 105 and the power-off of the relay output end of the disinfection controller 104 connected to the other end of the air purification module 108. This design enables the air purification module 108 and the disinfection module 106 to not work when the current time is not within the start and end time of the disinfection and purification set according to demand.

[0023] Reference Figure 1 ,in Figure 1The top one of the two front-end power lines 102 is the neutral line, and the bottom one is the live line. Similarly, the top one of the two rear-end power lines 103 is the neutral line, and the bottom one is the live line. As an embodiment of the present invention: when it is necessary to disinfect and purify the air inside the elevator car, the staff searches for the unique identification code sent by the Bluetooth module to the surrounding through the software on the mobile phone or Bluetooth device to complete the connection communication, and then first writes the current time data into the clock chip through the microprocessor controller of the disinfection controller 104 to ensure that the time of the clock chip in the disinfection controller 104 is consistent with the time, and then sets the disinfection and purification start and end time data according to the needs. The disinfection and purification start and end time data are stored in the FLASH memory through the microprocessor controller of the disinfection controller 104, and the microprocessor controller of the disinfection controller 104 reads the current time data inside the clock chip in real time and compares it with the disinfection and purification start and end time data as follows: When the compared current time data is not within the range of the start and end time data of the disinfection and purification, a signal is sent to the microprocessor controller of the disinfection and purification controller 104 to respectively control the power-off of the relay output end of the disinfection and purification controller 104 connected to the normally closed contact 105C of the control relay 105 and the power-off of the relay output end of the disinfection and purification controller 104 connected to the other end of the air purification module 108, so that when the current time is not within the start and end time of the disinfection and purification set according to the demand, the air purification module 108 and the disinfection and purification module 106 do not work; When the compared current time data is within the range of the start and end time data of the disinfection and purification, and when there is someone in the elevator, the elevator lighting 107 is turned on, and the coil 105A of the control relay 105 is energized, so that the normally open contact 105B of the control relay 105 connected to the input detection interface of the disinfection controller 104 is closed, so that the signal of the normally open contact 105B of the control relay 105 is sent to the microprocessor controller of the disinfection controller 104 to control the relay output end of the disinfection controller 104 connected to the normally closed contact 105C of the control relay 105 to cut off the power and the control relay 105 to control its normally closed contact 105C to open to close the disinfection module 106, and control the relay output end of the disinfection controller 104 connected to the other end of the air purification module 108 to energize to control the air purification module 108 to open; When the elevator is empty and the elevator is not running due to timeout, the elevator lighting 107 is turned off, and the coil 105A of the control relay 105 loses power, thereby opening the normally open contact 105B of the control relay 105 connected to the input detection interface of the disinfection controller 104, thereby sending a signal that the normally open contact 105B of the control relay 105 is opened to the microprocessor controller of the disinfection controller 104 to respectively control the relay output end of the disinfection controller 104 connected to the normally closed contact 105C of the control relay 105 to be energized and the control relay 105 to control its normally closed contact 105C to be closed to open the disinfection module 106, and control the relay output end of the disinfection controller 104 connected to the other end of the air purification module 108 to be de-energized to control the air purification module 108 to be closed, thereby facilitating effective safe and harmless disinfection and air purification of the elevator car, without the need to connect to the elevator system or install a human body sensor to identify whether there is someone for unmanned disinfection, and the structure is simple and easy to install.
