[0005] According to one embodiment of the utility model, the air handling system has a ventilation mode and a disinfection mode. In the ventilation mode, the fan module operates to ventilate the space, while the air quality detection module monitors the air quality of the space in real time. When the air quality detection module detects that the air quality of the space is substandard and the human body detection module detects that there are no users in the space, the air handling system enters the disinfection mode. The main control module activates the ozone disinfection module, the door control module, and / or the window control module.

[0006] According to one embodiment of the utility model, the human body detection module is a human body sensor. The human body sensor detects whether a user exists in the space and sends the information to the main control module.

[0007] According to one embodiment of the utility model, the human body detection module is a camera. The camera's field of view is the entire usable space. The camera takes a picture of the usable space and transmits it to the main control module. The main control module determines whether a user exists in the usable space based on the picture.

[0008] According to one embodiment of the utility model, it also includes an APP module, which connects the main control module and the human body detection module. The human body detection module transmits photos to both the main control module and the APP module simultaneously. The main control module controls the ozone disinfection module, the door control module, and the window control module according to the user's instructions.

[0009] According to one embodiment of the utility model, the human body detection module is installed on the ventilation device, or the human body detection module is independent of the ventilation device and installed in the use space.

[0010] According to one embodiment of the utility model, the ozone disinfection module includes an ozone generator and a blowing device. The blowing device is used to blow the ozone generated by the ozone generator to promote the diffusion of ozone in the use space.

[0026] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] Please see Figures 1 to 5 This utility model discloses an air handling system. The air handling system includes a ventilation device 1, an ozone disinfection module 2, a human body detection module 3, a door control module 4, and / or a window control module 5. The ventilation device 1 has a main control module 11, an air quality detection module 12, and a fan module 13, which are signal-connected to the main control module 11. The ozone disinfection module 2 is signal-connected to and controlled by the main control module 11. The human body detection module 3 is signal-connected to the main control module 11 and is used to detect human activity. The door control module 4 is signal-connected to and controlled by the main control module 11 and is used to control the opening and closing of the doors in the usable space. The window control module 5 is signal-connected to and controlled by the main control module 11 and is used to control the opening and closing of the windows in the usable space.

[0028] In this embodiment, the usable space can be a kitchen, a bathroom, or a storage room, etc. The usable space has a door for users to enter and exit. The usable space may also have windows for ventilation. A ventilation device 1 drives gas flow, for example, exhausting gas from the usable space to the outside, allowing fresh air to enter and ventilate the space. The ventilation device 1 can be a standalone fan, or a range hood or air purifier with a fan module 13, etc. An air quality detection device 12 detects the air quality within the usable space, for example, detecting PM2.5 concentration.

[0029] Human body detection module 3 is used to detect the presence of human activity in the space to confirm its occupancy. Ozone disinfection module 2 releases ozone, which sterilizes and purifies the air in the space, including walls and other exposed surfaces, improving air quality and reducing bacterial growth. Ozone has a broad bactericidal spectrum, killing bacteria, viruses, and various microorganisms, and also effectively removes mold, fishy smells, and other odors. After ozone disinfection, excess oxygen atoms recombine into oxygen within 30 minutes, producing no pollution and requiring minimal consumables.

[0030] Door control module 4 is used to drive the doors of the usable space to open or close, while window control module 5 is used to control the windows of the usable space to open or close. Door control module 4 and window control module 5 are electrically connected to main control module 11, allowing main control module 11 to control the opening or closing of doors and windows of the usable space via these modules. Specifically, taking door control module 4 as an example, it includes a first slide rail, a first pulley, a first drive motor, a first transmission gear, and a first transmission rack. The first slide rail is installed on the floor of the usable space, and the first pulley is installed at the bottom of the door, with the pulley rolling in conjunction with the first slide rail. The first drive motor is electrically connected to main control module 11, and its drive shaft is connected to the first transmission gear to drive its rotation. The first transmission gear meshes with the first transmission rack to convert the rotation of the first transmission gear into linear motion of the first transmission rack. The first transmission rack is connected to the door to move the door. Therefore, the main control module 11 can drive the door of the usable space to reciprocate along the first slide rail by controlling the drive shaft of the first drive motor to rotate forward or in the opposite direction, thereby controlling the door of the usable space to open or close.

[0031] Accordingly, the window control module 5 includes a second slide rail, a second pulley, a second drive motor, a second transmission gear, and a second transmission rack. The second slide rail is installed on the windowsill of the usable space, and the second pulley is installed at the bottom of the window, with the second pulley and the second slide rail in rolling engagement. The second drive motor is electrically connected to the main control module 11, and its drive shaft is connected to the second transmission gear to drive the gear to rotate. The second transmission gear meshes with the second transmission rack to convert the rotation of the gear into linear motion of the rack. The rack is connected to the window to move the window. Thus, the main control module 11 can control the window of the usable space to reciprocate along the second slide rail by controlling the drive shaft of the second drive motor to open or close.

[0032] The air handling system has a disinfection mode. The air quality detection module 12 first detects the air quality in the space. If the air quality meets the standards, disinfection is not required; if the air quality does not meet the standards, the ozone disinfection module 2 needs to be activated to release ozone for disinfection. Of course, before activating the ozone disinfection module 2, the human body detection module 3 needs to detect whether there is any user activity in the space. If there is user activity, the ozone disinfection module 2 will not be activated to prevent ozone from affecting the user's health; if there is no user activity, the ozone disinfection module 2 will be activated.

[0033] Air quality and the presence or absence of human activity in the usable space are the trigger conditions for the disinfection mode. When the air quality detection module 12 detects that the air quality in the usable space is substandard and the human detection module 3 detects that there are no users in the usable space, the air handling system enters the disinfection mode. The main control module 11 activates the ozone disinfection module 2, the door control module 4, and / or the window control module 5. The door control module 4 closes the door of the usable space and / or the window control module 5 closes the window of the usable space. The ozone disinfection module 2 releases ozone into the usable space. Ozone can disinfect and sterilize the air environment and walls of the usable space to improve the air quality. Since it has been confirmed that no one is in the usable space and the doors and windows are closed when ozone is released, it can both prevent ozone from affecting users and improve the sterilization effect of the usable space by closing the doors and windows.

[0034] In the air handling system of this invention, the air handling system also has a ventilation mode. In the ventilation mode, the fan module 13 operates to ventilate the space in use, while the air quality detection module 12 monitors the air quality of the space in real time. That is to say, if the air quality detection module 12 detects that the air quality of the space in use meets the standards, the air handling system will remain in the ventilation mode, and at this time, only the fan module 13 needs to refresh the air in the space in use.

[0035] In the air handling system of this invention, such as Figure 5 As shown, the human detection module 3 is a human sensor. The human sensor detects whether a user is present in the usage space and sends the information to the main control module 11. The human sensor can directly detect whether a user is present in the usage space. Compared with detecting human activity through methods such as lasers, the detection results of the human sensor are more accurate and reliable. This can further prevent the air handling system from mistakenly entering the disinfection mode when there is human activity in the usage space, thereby improving the safety performance of the air handling system.

[0036] In the air handling system of this invention, the human body detection module 3 is a camera. The camera's field of view covers the entire usable space. The camera captures a photo of the usable space and transmits it to the main control module 11. The main control module 11 determines whether a user is present in the usable space based on the photo. The main control module 11 has pre-stored comparison data for determining whether a human body is present in a photo. After the camera captures a photo of the usable space and transmits it to the main control module 11, the main control module 11 analyzes the image data of the photo and compares it with the pre-stored comparison data. If the data matches, it indicates that a user is present in the usable space. Detecting the presence of a human body in the usable space through photography makes the detection process more intuitive and effective, further improving the reliability of the detection results.

[0037] In the air handling system of this invention, such as Figure 5As shown, the system also includes an APP module, which connects the main control module 11 and the human body detection module 3. The human body detection module 3 transmits photos to both the main control module 11 and the APP module. The main control module 11 controls the ozone disinfection module 2, the door control module 4, and the window control module 5 according to user instructions. The APP module can be installed on the user's smart terminal, such as a mobile phone or smartwatch. This allows the smart terminal to communicate with the main control module 11 via the APP module, enabling the user to interact with the air handling system. After the human body detection module 3 takes a photo of the space, it transmits it to the user's smart terminal via the APP module. The user then determines whether a human is present in the space. Once the user confirms the absence of a human, they can control the door control module 4 and the window control module 5 to close the doors and windows and control the ozone disinfection module 2 to release oxygen. Using the APP module to allow users to control the air handling system to disinfect the space further improves the safety performance of the air handling system.

[0038] In the air handling system of this invention, such as Figure 3 As shown, the human body detection module 3 is installed on the ventilation device 1, or it can be installed independently of the ventilation device 1 within the usage space. If the ventilation device 1 is installed at a high position within the usage space, the human body detection module 3 can be installed on it, ensuring it is positioned high within the space and can detect the entire area from top to bottom, preventing blind spots. If the ventilation device 1 is installed at a low position, the human body detection module 3 can be installed independently of it, also ensuring it is positioned high within the space.

[0039] In the air handling system of this invention, such as Figure 4 As shown, the ozone disinfection module 2 includes an ozone generator 21 and a blowing device 22. The blowing device 22 is used to blow the ozone generated by the ozone generator 21 to promote the diffusion of ozone in the usage space. The ozone generator 21 can generate ozone through high-voltage discharge, ultraviolet irradiation, or electrolysis. The blowing device 22 is used to generate airflow to bring ozone into the usage space and diffuse it within the space. In this way, ozone can be diffused more quickly and fully throughout the usage space, improving the disinfection effect.

[0040] In the air handling system of this invention, such as Figure 4As shown, the ozone disinfection module 2 is installed on the ventilation device 1. In this way, the ozone disinfection module 2 can be installed together with the ventilation device 1 in the usable space without separate installation, thus improving the installation convenience of the air handling system. Furthermore, installing the ozone disinfection module 2 on the ventilation device 1 also serves to conceal and protect the ozone disinfection module 2.

[0041] In the air handling system of this invention, such as Figure 3 As shown, the ventilation device 1 is a range hood, which has a smoke collection chamber and an air intake communicating with the smoke collection chamber. A fan module 13 is located inside the smoke collection chamber. The range hood also has an electrical control chamber located at the front of the range hood's head. An ozone disinfection module 2 is located inside the electrical control chamber. An exhaust port is located on the bottom plate of the electrical control chamber. When the ozone disinfection module 2 is activated, ozone gas flows out through the exhaust port. When the range hood is running, the activation of the fan module 13 creates negative pressure at the air intake, thereby drawing the oil fumes near the air intake into the smoke collection chamber for purification before discharging them outside the usable space. Installing the ozone disinfection module 2 inside the electrical control chamber of the range hood improves the ease of installation and facilitates subsequent maintenance and replacement of the ozone module.

[0042] In the air handling system of this invention, such as Figure 1 As shown, the blower 22 can operate independently. When a cooktop is installed in the space, and the cooktop is running while the user is cooking, the fan module 13 starts, and the blower 22 activates, forming an air curtain between the user and the cooktop. When the user starts cooking, the range hood enters the fume extraction mode. In this mode, the fan module 13 extracts and exhausts the fumes generated during cooking, while the blower 22 activates to create an air curtain by blowing air downwards through the exhaust vents. This air curtain separates the fumes from the user, preventing them from directly hitting the user and improving the cooking experience. It is understood that in the fume extraction mode, the ozone generator 21 remains off to prevent ozone generation from affecting the user. Thus, the ozone disinfection module 2 can perform different functions in different operating modes of the range hood, thereby improving the overall operating efficiency of the air handling system.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
