Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to an openable and closable door and window based on gas leak detection. Background Technology
[0002] In daily life, natural gas is a commonly used energy source, widely used in home cooking and heating. However, gas leaks occur frequently, posing a serious threat to people's lives and property. When a gas leak occurs, if indoor doors and windows are closed, the gas will accumulate indoors, gradually increasing in concentration. Once it comes into contact with an open flame or electrical spark, it can easily cause serious accidents such as explosions or fires.
[0003] Currently, while some doors and windows on the market have certain intelligent functions, there are relatively few products that can detect gas leaks and automatically control the opening and closing of doors and windows. Even if some existing technologies can detect gas leaks and control the opening of doors and windows, there are still problems such as poor ventilation, low detection accuracy, and slow response speed, which cannot effectively reduce the indoor gas concentration in a timely manner and ensure the safety of people.
[0004] Therefore, developing a door and window system that can accurately detect gas leaks and quickly and effectively control the opening and closing of doors and windows while enhancing ventilation is of great practical significance. Utility Model Content
[0005] The purpose of this utility model is to provide an openable and closable door and window based on gas leak detection, in order to solve the problems mentioned in the background art: although some doors and windows on the market have certain intelligent functions, there are relatively few products that can detect gas leaks and automatically control the opening and closing of doors and windows. In some existing technologies, even if gas leaks can be detected and doors and windows can be opened, there are still problems such as poor ventilation, low detection accuracy, and slow response speed, which cannot effectively reduce the indoor gas concentration and ensure the safety of people in a timely manner.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An operable door and window based on gas leak detection, comprising: The window itself has a sliding open and sliding close state; The window body includes: window frame; An internally fixed window is fixedly installed in the upper part of the inner cavity of the window frame; An inward sliding window, which is slidably installed in the lower part of the inner cavity of the window frame; The fixed internal windows and the sliding internal windows are arranged alternately, one above the other. The inner sliding window can slide up and down within the window frame, and the window body can be opened or closed while sliding. A gas detection module is installed on one side of the inner wall of the window frame; The control module is installed on the other side of the inner wall of the window frame and is electrically connected to the gas detection module. The drive actuator is provided in two sets. The two sets of drive actuators are respectively installed on both sides of the top of the inner cavity of the window frame. One end of each set of drive actuators is connected to the inner sliding window. The two sets of drive actuators are connected in series and then electrically connected to the control module. A ventilation auxiliary module is installed on an internally fixed window and is electrically connected to a control module.
[0007] By adopting the above technical solution, the gas detection module installed on the inner wall of the window frame can detect the indoor gas concentration in real time and send a detection signal when the gas concentration exceeds the preset threshold. The control module is also installed on the inner wall of the window frame and is electrically connected to the gas detection module. It is used to receive the detection signal from the gas detection module and generate control commands. When the gas detection module detects that the gas concentration exceeds the preset threshold, it sends an electrical signal to the control module. After receiving the signal, the control module generates control commands and drives two sets of drive execution components. The two sets of drive execution components can drive the window body from the closed state to the open state or from the open state to the closed state according to the control commands. When the gas detection module detects that the gas concentration exceeds the preset threshold, it sends an electrical signal to the control module. Upon receiving the signal, the control module generates a control command to drive the ventilation auxiliary module. When the inner sliding window in the window body is opened, the control module activates the ventilation auxiliary module to enhance the circulation of indoor and outdoor air.
[0008] Preferably, the internally fixed window is composed of an upper inner window frame and an upper glass panel, wherein the upper inner window frame is fixedly installed in the upper part of the inner cavity of the window frame, and the upper glass panel is fixedly installed in the inner cavity of the upper inner window frame.

When the detection signal indicates that the gas concentration exceeds the preset threshold, it generates a control instruction to open the doors and windows. When the gas concentration decreases to a safe range, it generates a control instruction to close the doors and windows. The command output port is electrically connected to the control signal input terminals of both electric telescopic masts via wires, and is used to output control commands.
[0015] By adopting the above technical solution, the signal receiving port in the controller is used to receive the detection signal transmitted by the gas alarm. The instruction generation unit in the controller can compare the received detection signal with the preset threshold. When the detection signal indicates that the gas concentration exceeds the preset threshold, a control instruction to open the doors and windows is generated. When the gas concentration drops to a safe range, a control instruction to close the doors and windows is generated. The instruction output port in the controller can send control instructions to the two electric telescopic rods respectively, so that they can perform the work of opening the inner sliding window.

[0037] In this embodiment, when the two electric telescopic rods 70 receive instructions from the control module to operate, the extension and retraction of the piston rods of the two electric telescopic rods 70 enables the inner sliding window to move up and down within the window frame 10.
[0038] Furthermore, the control module is a controller 60, which is fixedly installed on one side of the inner wall of the window frame 10. The gas detection module is a gas alarm 100, which is fixedly installed on the inner wall of the window frame 10 and away from the controller 60. The controller 60 has the following features: The signal receiving port is electrically connected to the signal output terminal of the gas alarm 100 via a wire and is used to receive detection signals; The instruction generation unit compares the received detection signal with a preset threshold.

When the gas concentration decreases to a safe range, it generates a control instruction to close the doors and windows. The command output port is electrically connected to the control signal input terminals of both electric telescopic rods 70 via wires, and is used to output control commands.
[0039] In this embodiment, the signal receiving port in the controller 60 is used to receive the detection signal transmitted by the gas alarm 100.

The control module is also installed on the inner wall of the window frame 10 and is electrically connected to the gas detection module. It is used to receive the detection signal from the gas detection module and generate control commands. When the gas detection module detects that the gas concentration exceeds the preset threshold, it sends an electrical signal to the control module. After receiving the signal, the control module generates control commands and drives two sets of drive actuators. The two sets of drive actuators can drive the window body from the closed state to the open state or from the open state to the closed state according to the control commands. When the gas detection module detects that the gas concentration exceeds the preset threshold, it sends an electrical signal to the control module. Upon receiving the signal, the control module generates a control command to drive the ventilation auxiliary module. When the inner sliding window in the window body is opened, the control module activates the ventilation auxiliary module to enhance the circulation of indoor and outdoor air. When the gas concentration exceeds the preset threshold, the command output port in the control module simultaneously triggers the alarm module. After the command output port in the control module simultaneously triggers the alarm module, the audible and visual alarm 120 can emit a clear audible and visual signal to remind people indoors to pay attention to the gas leak.
[0048] In summary: I. Precise Detection and Rapid Response: The gas detection module detects the indoor gas concentration in real time. Once the preset threshold is exceeded, the control module can quickly generate instructions to drive the relevant components to work, thus achieving a rapid response to gas leaks. II. Effective ventilation: The system uses an internal sliding window opening mechanism combined with a ventilation auxiliary module (exhaust fan 110), which, compared to traditional single door and window opening, can more effectively enhance indoor and outdoor air circulation and quickly reduce indoor gas concentration. Third, dual protection: While automatically opening doors and windows for ventilation, it triggers an audible and visual alarm, which can promptly remind people indoors, buying time for evacuation and taking countermeasures, and further protecting people's lives.
