Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method for elevator air conditioning and an elevator air conditioning system. Background Technology

[0002] With urbanization, elevators have become an indispensable mode of transportation in high-rise buildings. Every day, different people enter and exit elevators, and their breathing and the objects they carry can spread various harmful bacteria, viruses, and other pathogens. These pathogens multiply rapidly within the sealed elevator car space and spread quickly through the air and contact, making elevators a breeding ground for viruses. Currently, elevator disinfection still relies on manual spraying of disinfectants by cleaning staff. During flu season, this manual disinfection exacerbates the risk of flu transmission, and it is difficult to target and reduce the risk of flu transmission after virus carriers have entered or exited the elevator. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a control method for elevator air conditioning. The elevator air conditioning system can accurately identify individuals with elevated body temperatures entering the elevator and stop operating the air conditioning fan when such individuals enter, preventing further spread of influenza viruses. After individuals leave the elevator, a disinfectant spray device is controlled to disinfect the air inside the elevator for a preset time, promptly eliminating any viruses that may be carried in the air and preventing subsequent passengers from coming into contact with the potentially hazardous air inside the elevator, thus reducing the risk of influenza transmission.

[0004] This invention also provides an elevator air conditioner.

[0005] According to a first aspect of the present invention, the elevator air conditioner includes a temperature detection device, a biometric identification device, and a disinfectant spraying device. The temperature detection device is located at the elevator entrance. The biometric identification device is used to detect the number of people inside the elevator and their entry and exit. The disinfectant spraying device is installed on the top of the elevator. The elevator air conditioner control method includes:

[0006] In response to the elevator door opening signal, the body temperature of the people entering the elevator is obtained;

[0017] According to one embodiment of the present invention, the elevator air conditioner includes multiple air outlets, and the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel in the elevator have left the elevator further includes:

[0018] The swing angles of the air guide plates at the multiple air outlets are different at the same time. When the multiple air guide plates swing outward or inward simultaneously relative to the center of the elevator air conditioner, the swing angles at the same time differ by a predetermined angle.

[0019] According to one embodiment of the present invention, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all the people in the elevator have left the elevator further includes:

[0020] The concentration of disinfectant in the air inside the elevator was detected;

[0021] If the concentration of the disinfectant solution is determined to be greater than or equal to a preset concentration, the elevator is controlled to be in a closed state, and the elevator air conditioner is controlled to operate in fresh air mode for a fourth preset duration; wherein, the fourth preset duration is directly proportional to the concentration of the disinfectant solution.

[0022] If the concentration of the disinfectant is determined to be less than the preset concentration, a pre-opening signal is generated and sent to the elevator's control system.

[0023] According to an embodiment of the present invention, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel in the elevator have left the elevator further includes:

[0024] In response to the signal that the elevator door opens on this floor, the first actual duration of the disinfectant spraying device disinfecting the air inside the elevator is obtained.

[0025] If the first actual duration is determined to be less than the first preset duration, the elevator will remain in the closed state until the disinfectant spraying device disinfects the air inside the elevator for the first preset duration.

[0026] If the first actual duration is determined to be greater than or equal to the first preset duration, then the elevator is controlled to open its door on this floor.

[0027] According to an embodiment of the present invention, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel in the elevator have left the elevator further includes:

[0028] In response to a signal that the elevator is called from outside the current floor, the elevator is controlled to run to the called floor, and the second actual duration of the disinfectant spraying device disinfecting the air inside the elevator is obtained.

[0029] If the second actual duration is determined to be less than the first preset duration, the elevator will remain in the closed state until the disinfectant spraying device disinfects the air inside the elevator for the first preset duration.

[0030] If the second actual duration is determined to be greater than or equal to the first preset duration, then the elevator is controlled to open the door at the floor where the call was made.

[0031] According to one embodiment of the present invention, the elevator air conditioner includes a microphone assembly and a plurality of prompting components, wherein the plurality of prompting components are respectively installed at different positions inside the elevator. Then, the step of determining that the person's body temperature is greater than or equal to a preset temperature further includes:

[0032] The noise level inside the elevator, the structural information of the elevator, the arrangement information of the prompting components, and the location information of the people inside the elevator are obtained.

[0033] The prompting component is controlled to issue a prompting message based on the noise level, the structural information, the arrangement information, and the location information.

[0034] An elevator air conditioner according to a second aspect of the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the steps of the control method for the elevator air conditioner according to a first aspect of the present invention.

[0035] The above-described one or more technical solutions of this invention have at least one of the following technical effects:

[0036] According to the elevator air conditioning control method provided in this embodiment of the invention, the elevator air conditioning system includes a temperature detection device, a biometric identification device, and a disinfectant spraying device. The temperature detection device is located at the elevator entrance, the biometric identification device is used to detect the number of people in the elevator and their entry and exit, and the disinfectant spraying device is installed on the top of the elevator. The elevator air conditioning control method includes: responding to an elevator door opening signal to obtain the body temperature of the person entering the elevator; if the person's body temperature is greater than or equal to a preset temperature, controlling the elevator air conditioning fan to stop operating; and controlling the disinfectant spraying device to disinfect the air in the elevator for a first preset time after all the people in the elevator have left the elevator. When a person enters the elevator, the temperature detection device promptly obtains the person's body temperature. If the person's body temperature exceeds the preset temperature, for example, 37.3 degrees Celsius, and there is a risk of influenza transmission in the air inside the elevator, the elevator air conditioning fan is promptly shut off to slow down the airflow speed inside the elevator. Secondly, after all the people in the elevator have left the elevator, the air inside the elevator is promptly disinfected by the disinfectant spraying device for a duration of the first preset time, preventing subsequent passengers from coming into contact with air that may have carried the influenza virus, reducing the risk of influenza virus transmission, and improving the safety of the air inside the elevator. Furthermore, the elevator air conditioning automatically disinfects the air inside the elevator, eliminating the need for manual operation by cleaning staff and further reducing the risk of influenza transmission.

[0045] The elevator air conditioner provided in this embodiment of the invention is installed on the top or side wall of the elevator. The elevator air conditioner includes components such as a compressor, a first heat exchanger, a second heat exchanger, an electronic expansion valve, and a four-way valve. These components are connected via refrigerant pipelines to form a refrigerant circulation loop. Fans are installed at both the first and second heat exchangers to regulate temperature and airflow within the elevator. The elevator air conditioner also includes a disinfectant spraying device installed at the top of the elevator, which sprays disinfectant into the elevator interior. The spraying speed of the disinfectant is adjustable. The elevator air conditioner further includes a temperature detection device and a biometric identification device. The temperature detection device is installed at the top of the elevator or on the inner wall facing the elevator door, directly opposite the elevator entrance, and can detect the body temperature of passengers upon entry. The biometric identification device is installed at the top or side wall of the elevator to detect the number of people inside the elevator and their entry and exit status, which is determined by the increase or decrease in the number of people.

[0046] Please refer to the elevator air conditioning control method provided in the first aspect embodiment of the present invention. Figure 1 as well as Figure 2 The control methods for elevator air conditioning include:

[0047] S100: In response to the elevator door opening signal, obtain the body temperature of the person entering the elevator.

[0048] S200: If the body temperature of a person is greater than or equal to the preset temperature, the elevator air conditioner fan will be stopped, and the disinfectant spraying device will be controlled to disinfect the air in the elevator for a first preset time after all the people in the elevator have left the elevator.

[0049] In step S100, when the elevator is stopped at the ground floor or any floor of a high-rise building, pressing the up or down button will generate an elevator door opening signal. When the elevator air conditioning control device receives the elevator door opening signal, it uses a temperature detection device to detect the body temperature of the person entering the elevator. The temperature detection device is positioned directly opposite the elevator entrance, so the person's body temperature can be measured immediately upon entering the elevator.

[0050] In some cases, temperature detection devices use multiple checks when measuring the body temperature of people entering an elevator. For example, checks may be taken at 0, 3, 6, and 9 seconds after entry. The purpose of these multiple checks is to avoid the influence of outdoor ambient temperature on the temperature of the person's head and skin. For instance, in winter, when outdoor temperatures are low, the skin on the head cools down due to the cold air and takes a certain amount of time to recover after entering the room and elevator. Therefore, taking multiple temperature checks at intervals after entry eliminates the influence of outdoor ambient temperature on body temperature. The principle is that the first few checks determine how quickly the body temperature recovers to its true value, while the later checks determine whether the body temperature has stabilized, thus ensuring the accuracy of the test results.

[0051] In step S200, when there are multiple people, the number of their body temperatures can vary. Determining a person's body temperature is greater than or equal to a preset temperature means that at least one person's temperature is greater than or equal to the preset temperature, for example, ≥37.3 degrees Celsius. In this case, the elevator's air conditioning fan stops operating to reduce the airflow speed inside the elevator, minimizing the spread of the feverish person's exhaled air within the elevator or contaminating other passengers, thus minimizing the spread of the influenza virus. Secondly, when a fever is detected in the elevator, the number of people inside is continuously monitored using a biometric device. An increase in the number of people indicates someone has entered the elevator, and a decrease indicates someone has exited. Therefore, the number of people can be 0, 1, 2, 3, 4… and the entry and exit of people can be represented by 0, ±1, ±2, ±3, ±4, etc. In some cases, only 1 represents someone in the elevator, and 0 represents all people have left. Once it is determined that all people have left the elevator, the disinfectant spray device is controlled to disinfect the air inside the elevator for a first preset time. The first preset time can be 6 seconds, or it can be determined based on the elevator's spatial structure and the disinfectant spray flow rate. The elevator uses a disinfectant spray system to sterilize the air that a person with a fever has been in contact with, preventing subsequent passengers from coming into contact with air that may have carried the flu virus. This improves the safety of the elevator's air and reduces the risk of flu transmission. Furthermore, the elevator's air conditioning system automatically disinfects the air, eliminating the need for manual operation by cleaning staff and further reducing the risk of flu transmission.

[0052] In some embodiments, the step of stopping the operation of the elevator air conditioner fan further includes:

[0053] S208. Detect the number of people in the elevator using a biometric device.

[0054] S209. If the number of people is determined to be zero, then all people in the elevator must leave the elevator.

[0055] In steps S208 and S209, the number of people in the elevator is detected by a biometric device installed in the elevator. Therefore, the number of people can be 0, 1, 2, 3, 4, etc. When all the people in the elevator leave, the biometric device detects that the number of people in the elevator is 0. At this time, the elevator is turned off and the disinfectant spraying device is controlled to run for a first preset time to thoroughly disinfect the air in the elevator.

[0056] According to one embodiment of the present invention, after all personnel in the elevator have left the elevator, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time further includes:

[0057] S310, Obtain the air humidity inside the elevator.

[0058] S320. If the air humidity is determined to be greater than or equal to the preset humidity, control the elevator air conditioner to operate in dehumidification mode for the second preset duration and adjust the elevator air conditioner fan to the maximum speed.

[0059] In step S200, after all passengers have left the elevator, disinfectant is sprayed inside to eliminate viruses present or potentially present in the air. However, during continuous elevator operation, the freshly sprayed disinfectant mist may increase the humidity inside the elevator. In steps S310 and S320, the humidity inside the elevator is detected by the humidity sensor integrated into the elevator air conditioner, and the control strategy for the elevator air conditioner is determined based on the humidity. When the humidity is greater than or equal to a preset humidity level, passengers inside the elevator will experience a noticeable dampness. At this time, the elevator air conditioner is controlled to operate in dehumidification mode for a second preset duration. During dehumidification, the elevator air conditioner fan is adjusted to its maximum speed to accelerate the dehumidification of the air inside the elevator, thereby maintaining the efficient operation of the elevator and ensuring efficient circulation of people in high-rise buildings.

[0060] At the same time, adjusting the elevator air conditioner fan to its maximum speed helps the mist-like disinfectant to fully contact the air inside the elevator, achieving efficient disinfection within a limited disinfection time (before the next call to open the door), rather than simply improving dehumidification efficiency.

[0061] It should be noted that in step S320, when controlling the elevator air conditioner's dehumidification mode for the second preset duration based on air humidity, the higher the air humidity, the longer the second preset duration; the two are positively correlated. Air humidity can be divided into multiple levels, each corresponding to a different second preset duration; alternatively, a linear relationship can be established between air humidity and the second preset duration.

[0062] According to one embodiment of the present invention, a manifold is provided at the bottom of the elevator, and the elevator air conditioner also includes a water spraying device installed at the top of the elevator. After all personnel have left the elevator, the system further includes a step of controlling the water spraying device to disinfect the air inside the elevator for a first preset time, followed by:

[0063] S330, Inspect the cleanliness of the elevator's interior walls.

[0064] S340. The water spraying device is controlled to clean the inner wall of the elevator for a third preset time according to the degree of cleanliness; wherein the degree of cleanliness is inversely proportional to the third preset time.

[0065] In step S200, the elevator is sprayed with disinfectant to eliminate viruses carried in the air inside the elevator. However, after repeated spraying for a long time, the disinfectant may form stains on the inner wall of the elevator, which will affect the appearance of the elevator.

[0066] In step S330, the cleanliness of the elevator's inner wall can be detected through regular personnel inspections or sensor scanning. In step S340, based on the cleanliness of the elevator's inner wall, it is determined whether cleaning is necessary and what cleaning strategy should be adopted. When the cleanliness level meets the standard for cleaning, the water spraying device is controlled to clean the elevator's inner wall for a third preset time. The lower the cleanliness level, the longer the cleaning time is required; that is, the cleanliness level is inversely proportional to the third preset time.

[0067] It should be noted that the degree of cleanliness refers to the area of ​​stains on the inner wall per unit area, or the total length of stains on a single inner wall.

[0068] According to one embodiment of the present invention, the elevator air conditioner further includes a camera component for detecting light intensity, and the step of detecting the cleanliness of the inner wall of the elevator specifically includes:

[0069] S331. Obtain the reflectivity of the elevator's inner wall using a camera component.

[0070] S332. Determine the cleanliness of the elevator interior wall based on the reflectivity and preset reflectivity; wherein, the reflectivity is directly proportional to the cleanliness.

[0071] In this embodiment, the elevator air conditioner also includes a camera component, which is installed at a fixed position in the elevator. When the elevator lights are on and the elevator interior is completely clean, the camera component can detect a preset reflective intensity, which is relatively high at this time. As the number of disinfection cycles increases, stains appear on the elevator interior, at which point the reflective intensity decreases. Therefore, the cleanliness of the elevator interior can be determined based on the difference or ratio between the measured reflective intensity and the preset reflective intensity, where a higher reflective intensity indicates a higher level of cleanliness.

[0072] According to one embodiment of the present invention, the elevator air conditioner includes multiple air outlets. The step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel have left the elevator further includes:

[0073] S400: Control the air guide plates at multiple air outlets to swing at different angles at the same time. When multiple air guide plates swing outward or inward simultaneously relative to the center of the elevator air conditioner, the swing angles at the same time differ by a predetermined angle.

[0074] In step S400, the oscillation of the air guide plate makes the airflow blown out by the air conditioner circulate, which improves the air supply effect, enhances the uniformity of air supply and temperature in the elevator, improves the contact efficiency between the mist disinfectant and the air, and eliminates the variation in the size of the airflow distribution range. In addition, since the oscillation angle of each air guide plate is different, the opening of the total air outlet of the air conditioner is balanced, which reduces the air supply noise and makes the noise relatively stable, resulting in less noise pollution.

[0075] According to one embodiment of the present invention, after all personnel in the elevator have left the elevator, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time further includes:

[0076] S510. Detect the concentration of disinfectant in the air inside the elevator.

[0077] S520. If the concentration of disinfectant is greater than or equal to the preset concentration, the elevator is controlled to be in the closed state, and the elevator air conditioner is controlled to operate in the fresh air mode for the fourth preset time; wherein, the fourth preset time is directly proportional to the concentration of disinfectant.

[0078] S530. If the concentration of disinfectant is determined to be less than the preset concentration, a pre-opening signal is generated and sent to the elevator control system.

[0079] In step S200, the elevator is sprayed with disinfectant to eliminate viruses carried in the air inside the elevator. However, after disinfection, the elevator needs to be put into operation again. Therefore, the air inside the elevator may be filled with the smell of disinfectant. If the concentration of disinfectant is too high, it will cause breathing difficulties for people.

[0080] In S510, the concentration of disinfectant in the air inside the elevator is detected by a detection element, and then the operation mode of the elevator air conditioner is controlled according to the concentration of disinfectant.

[0081] In step S520, when the concentration of disinfectant is higher than the preset concentration, the elevator is kept in the closed state. Even if there is a signal to call the elevator to open the door, the elevator door is kept closed. Then, the elevator air conditioner is controlled to run in fresh air mode and run for a fourth preset time. The higher the concentration of disinfectant, the longer the fourth preset time, to ensure sufficient fresh air exchange.

[0082] In step S530, when the disinfectant concentration is lower than a preset concentration, a pre-opening signal is generated. This pre-opening signal is a safety signal. When the elevator receives another opening signal based on the pre-opening signal, it opens, indicating that the disinfectant concentration inside the elevator meets the standard.

[0083] According to one embodiment of the present invention, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel have left the elevator further includes:

[0084] S211. In response to the signal that the elevator door opens on this floor, the first actual duration of the disinfectant spraying device disinfecting the air inside the elevator is obtained.

[0085] S212. If the first actual duration is less than the first preset duration, then keep the elevator in the closed state until the disinfectant spraying device disinfects the air inside the elevator for the first preset duration.

[0086] S213. If the first actual duration is greater than or equal to the first preset duration, then control the elevator to open the door on this floor.

[0087] In step S211, the disinfectant spraying device starts working after all personnel have left the elevator. However, the disinfectant spraying device needs to run for a first preset time before it can fully disinfect the air inside the elevator. During the operation of the disinfectant spraying device, if someone on the same floor calls for the elevator door to open, for example, by pressing the up or down button, it is unclear whether the air inside the elevator that has been in contact with the feverish patient has been completely disinfected. This needs to be determined based on the first actual running time of the disinfectant spraying device.

[0088] In step S212, if the first actual duration is less than the first preset duration, it means that the disinfectant spraying device is still running and the risky air in the elevator has not been completely disinfected. The elevator cannot be opened immediately, but must remain closed until the disinfectant spraying device has been running for the first preset duration before the elevator door is opened to ensure that the risky air in the elevator is completely disinfected.

[0089] In some cases, a notification device outside the elevator can indicate to people that a disinfectant spraying device is in operation and also indicate the time until the elevator doors open. This can alleviate the anxiety or confusion of users waiting outside the elevator and make them feel more at ease.

[0090] In step S213, when the first actual duration is greater than or equal to the first preset duration, it indicates that the disinfectant spraying device has finished operating, the risky air inside the elevator has been completely disinfected, and the elevator can open in response to the door opening signal.

[0091] According to one embodiment of the present invention, the step of controlling the disinfectant spraying device to disinfect the air inside the elevator for a first preset time after all personnel have left the elevator further includes:

[0092] S221. In response to a signal that the elevator is called from outside the current floor, the elevator is controlled to run to the called floor, and the second actual duration of the disinfectant spraying device disinfecting the air inside the elevator is obtained.

[0093] S222. If the second actual duration is less than the first preset duration, then keep the elevator in the closed state until the disinfectant spraying device disinfects the air inside the elevator for the first preset duration.

[0094] S223. If the second actual duration is greater than or equal to the first preset duration, then control the elevator to open the door of the called floor.

[0095] In step S221, the disinfectant spraying device starts working after all personnel have left the elevator. However, the disinfectant spraying device needs to run for a first preset time to completely disinfect the air inside the elevator. During the operation of the disinfectant spraying device, if someone outside the current floor calls for the elevator to open, for example by pressing the up or down button, the elevator should run to the called floor according to the call instruction. However, it is not clear whether the air inside the elevator that has been in contact with a feverish patient has been completely disinfected, and this needs to be determined based on the second actual time of the disinfectant spraying device.

[0096] In step S222, when the second actual duration is less than the first preset duration, it means that the disinfectant spraying device is still running and the risky air in the elevator has not been completely disinfected. The elevator cannot be opened immediately, but must remain closed until the disinfectant spraying device has been running for the first preset duration before the elevator door is opened to ensure that the risky air in the elevator is thoroughly disinfected.

[0097] In step S223, when the second actual duration is greater than or equal to the first preset duration, it indicates that the disinfectant spraying device has finished operating, the risky air inside the elevator has been completely disinfected, and the elevator can open in response to the door opening signal.

[0098] According to one embodiment of the present invention, the elevator air conditioner includes a microphone assembly and multiple prompting components, which are respectively installed at different locations inside the elevator. After determining that a person's body temperature is greater than or equal to a preset temperature, the system further includes:

[0099] S231. Obtain the noise level inside the elevator, the structural information of the elevator, the layout information of the prompting components, and the location information of the people inside the elevator;

[0100] S232. Control the prompting component to issue prompting information based on noise level, structural information, layout information, and location information.

[0101] Understandably, the virus spreads widely during flu season. On the one hand, it's necessary to ventilate and disinfect elevators where people are densely populated. On the other hand, it's also necessary to remind people in elevators to take timely protective measures to prevent further spread of the flu. For example, if a person with a fever is detected entering the elevator, the alert system should promptly send a notification to remind the person with the fever to take self-protective measures, and also remind other passengers to take preventative measures.

[0102] When there are many people or the noise inside the elevator is loud, people may have difficulty paying attention to the prompts emitted by the notification component, which could lead to further spread of the flu. Therefore, in steps S231 and S232, the notification component can be controlled to emit prompts based on noise level, structural information, layout information, and location information. Specifically, the noise level inside the elevator is obtained through a microphone component. When the noise level is high, people inside the elevator may have difficulty concentrating on receiving the prompts. The elevator's structural information, the layout information of the notification component (including its location and orientation), and the location information of the people inside the elevator all affect the efficiency with which people receive the prompts.

[0103] In step S232, the prompting components can be controlled to issue prompting information based on the elevator structure where the user is located, the arrangement of surrounding prompting components, and the location of the person. The prompting information can be voice broadcast information or alarm information, such as "High body temperature, take precautions".

[0104] In some cases, the prompting components include not only voice prompts, but also displays, vibrators, or flashing lights.

[0105] In some embodiments, the step of controlling the prompting component to issue a prompting message based on noise level, structural information, layout information, and location information specifically includes:

[0106] S2321. Adjust the volume and repetition number of the prompt message emitted by the prompt component according to the noise level.

[0107] S2322. Based on structural information, layout information, and location information, determine the nearest prompting component to the person inside the elevator and issue a prompting message.

[0108] In step S2321, noise levels can be divided into different grades. The higher the noise level, the louder the prompt message. Alternatively, a linear relationship can be established between the two to ensure that the volume of the prompt message is always greater than the volume of the noise. Simultaneously, as the noise level increases, the repetition frequency of the prompt message can be appropriately increased to enhance the likelihood of people receiving the prompt message.

[0109] In some embodiments, after receiving a notification, if the people in the elevator determine that there is a person with a fever or a risk of influenza transmission in the elevator, they will remain silent for safety reasons. At this time, the noise level will be reduced to a silent state, indicating that the people in the elevator have received the notification. This can be used as an indicator of whether the notification has been properly conveyed.

[0110] In step S2322, the location of the nearest prompting component to the person in the elevator can be determined based on the elevator's structural information, the arrangement information of the prompting component, and the person's location information in the elevator (obtained through a biometric device). By controlling the prompting component to issue a prompting message, it can be ensured that the person accurately receives the prompting message.

[0111] An elevator air conditioner according to a second aspect of the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the steps of the control method for the elevator air conditioner according to a first aspect of the present invention.

[0112] When the elevator air conditioning is running: In response to the elevator door opening signal, it acquires the body temperature of people entering the elevator. If the body temperature is greater than or equal to a preset temperature, it stops the elevator air conditioning fan and, after all people have left the elevator, controls the disinfectant spray device to disinfect the air inside the elevator for a first preset time. When people enter the elevator, the temperature detection device promptly acquires their body temperature. If a person's body temperature exceeds the preset temperature, for example, 37.3 degrees Celsius, indicating a risk of influenza transmission in the elevator air, the elevator air conditioning fan is immediately shut off to slow the airflow. Secondly, after all people have left the elevator, the disinfectant spray device promptly disinfects the air inside the elevator for the first preset time, preventing subsequent passengers from coming into contact with air that may have carried the influenza virus, reducing the risk of influenza transmission and improving the safety of the air inside the elevator. Furthermore, the elevator air conditioning automatically disinfects the air inside the elevator, eliminating the need for manual operation by cleaning staff, further reducing the risk of influenza transmission.

[0113] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
