Description

Technical Field

[0001] The utility model relates to the technical field of elevator car purification, and particularly relates to a radar induction control car purifier. Background Art

[0002] With the acceleration of the urbanization process, people pay more and more attention to the indoor air quality, especially the air quality in enclosed spaces. With the use of car elevators with electric motors as power in medium and high-rise buildings, which use box-shaped pods to carry people or goods in multi-story buildings, the use of car elevators is becoming more and more widespread.

[0003] Due to the small and enclosed car space, harmful gases and microorganisms are likely to accumulate, posing a threat to the health of passengers, and the air quality inside the car has received extensive attention. Traditional car purifiers are mostly manually adjusted or in a single mode, running continuously inside the car, unable to automatically adjust according to changes in the internal environment of the car and whether there are people. There are safety hazards when using the ultraviolet sterilization mode when there are people, so there is an urgent need for an intelligent solution, an air purification device that can intelligently judge whether there are people in the car and automatically adjust the working state accordingly.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A radar induction control car purifier, including a housing, a purification device, and a radar induction device. The housing is a rectangular box structure, provided with an air inlet and an air outlet. The purification device is arranged at the top inside the housing, and the radar induction device is arranged at the front end inside the housing. On both sides of the radar induction device, a safety monitoring module and a control module are respectively arranged.

[0006] Preferably, the purification device includes a HEPA filter, an activated carbon filter layer, and an ultraviolet lamp tube.

[0007] Preferably, the radar induction device is a microwave radar sensor.

[0008] Preferably, the control module is connected to the radar induction device, the purification device, and the safety control module through a circuit board.

[0010] Preferably, the heat dissipation holes are small round holes, and each small round hole is arranged in a "rice" shape with each other.

[0011] Preferably, screw fixing holes are arranged on the top of the housing.

[0012] Beneficial effects of the utility model: The radar sensing controlled car purifier device provided by the utility model monitors the status of people in the car through a microwave radar sensor set at the front end, transmits the information to the control unit, and the control unit controls the purification device to turn on ultraviolet irradiation to implement air purification in the elevator car. When someone is detected, the control unit instructs to turn off the ultraviolet lamp and only uses physical and chemical filtering modes for air purification to avoid harm to the human body. The device uses the signal of the radar sensing device to intelligently control the purification device, effectively avoiding the potential harm of ultraviolet rays to the human body, and improving the purification efficiency and safety of use.

DETAILED DESCRIPTION

[0016] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0017] Reference Figure 1 and Figure 2 The utility model provides a radar sensing controlled car purifier, which includes a shell 1, a control module 2, a radar sensing device 3, a safety monitoring module 4 and a purification device 5. The shell 1 is designed as a rectangular box, made of lightweight, high-strength aluminum alloy material, and the surface is anti-corrosive treated to ensure the safety of the shell 1. There are screw fixing holes 103 on the top of the shell 1, and the purifier is fixed on the top of the car by screws, which is simple to install. The front end of the shell 1 has an air inlet 102 and an air outlet 101, and the purifier circulates and replaces air when working. Heat dissipation holes 104 are designed at both ends of the shell 1. The heat dissipation holes 104 are small circular holes, and the small circular holes are arranged in a "rice" shape with each other to ensure that the purifier can operate stably for a long time.

[0018] A radar sensing device 3 is provided inside the shell 1 and installed at the front end of the shell 1 to ensure that the interior space of the car can be fully covered. The radar sensing device 3 uses a microwave radar sensor, which can penetrate non-metallic objects inside the car, accurately monitor whether there is someone in the car, and send the data to the control module 2.

[0019] The control module 2 and the safety monitoring module 4 are installed on both sides of the radar sensing device 3, and are connected to the radar sensing device 3, the purification device 5 and the safety monitoring module 4 through the circuit board. The control module 2 adopts a high-performance microprocessor with a built-in intelligent algorithm. After receiving the signal from the radar sensing device 3, it intelligently adjusts the working state of the purification unit according to the signal and manages the safety monitoring module 4 at the same time. The safety monitoring module 4 is used to monitor the working state of the ultraviolet lamp 503, to ensure that the ultraviolet lamp is automatically turned off when someone is present to protect the health of passengers, and to quickly cut off the power supply to ensure safety when the ultraviolet light is accidentally turned on.

[0020] The purification device 5 includes a HEPA filter 501, an activated carbon filter layer 502, and an ultraviolet lamp 503. When the purifier is working, the air first passes through the HEPA 501 filter and the activated carbon filter layer 502 to remove particulate matter and harmful gases, and then passes through the ultraviolet lamp 503 for disinfection, providing a cleaner and healthier cabin environment. When no one is in the purification device 5, the ultraviolet lamp 503 is turned on for deep disinfection, and when someone is there, the ultraviolet lamp is turned off to avoid harm to the human body.

[0021] Example

[0022] The elevator car of a commercial building is selected and the purifier of the utility model is installed to purify the air in the car. When no one is in the car, the control module 2 analyzes the current purification demand and instructs the purification device 5 to work at an appropriate wind speed and mode. The radar sensor 3 transmits this information to the control module 2, and the purifier automatically turns on ultraviolet sterilization and other purification modes to thoroughly purify the air; when someone enters the car, the radar sensor 3 immediately detects it and instructs the purifier to turn off ultraviolet irradiation through the control module 2, and only uses physical and chemical filtration modes for air purification until the person leaves, ensuring the health of the passengers.

[0023] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
