[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3A gas detection safety warning device includes a gas collecting box 1 with a detection tube 2 fixedly connected to the top. The gas collecting box 1 is a rectangular structure, and a connecting component is installed on the top of the detection tube 2, so that the user can fix the gas collecting box 1 on the ceiling of the building through the connecting component when in use.

[0028] A detection component for detecting harmful gases is fixedly connected to the periphery of the detection tube 2, and an air suction component for drawing air into the gas collecting box 1 is fixedly connected to the outer walls on the four sides. The indoor ambient air is transported to the detection tube 2 through the air suction component, and the gas inside the detection tube 2 is detected by the detection component to determine whether there is any leakage of harmful gas in the room.

[0029] The end of the air intake component away from the air collecting box 1 is fixedly connected to an exhaust pipe 12 with an air inlet hole 13 on the outer surface. The exhaust pipe 12 is a hose structure. The end of the exhaust pipe 12 away from the air intake component is sealed. The exhaust pipe 12 is sleeved with a fixing part for fixing the exhaust pipe 12. The user can fix the positions where the air inlet holes 13 on multiple exhaust pipes 12 are opened to the positions where harmful gas leakage may exist in the indoor environment through the fixing parts. When the air intake component is started, the air near the air inlet hole 13 can be sucked into the exhaust pipe 12 through the air inlet hole 13, and transported along the exhaust pipe 12 to the inside of the detection tube 2 for detection.

[0030] A control device for controlling the start and stop of the vacuum assembly is also fixedly connected to the outer surface of the detection tube 2. The control device can control the alternating start-up of multiple vacuum assemblies to prevent gases from entering multiple detection areas inside the gas collecting box 1 at the same time. When there is a harmful gas leak in one of the detection areas, the gas transported from the non-leaking area to the gas collecting box 1 will be mixed with the harmful gas, resulting in a decrease in the concentration of the harmful gas, which affects the detection of the detection component.

[0031] Reference Figure 1 The connection assembly includes a mounting plate 5 fixedly connected to the top of the detection tube 2, and bolts 6 are penetrated on the periphery of the mounting plate 5. The bolts 6 penetrate the mounting plate 5 and are screwed to the building ceiling. An exhaust hole 3 is opened on the side wall of the detection tube 2 below the connection assembly. When in use, the user aligns the mounting plate 5 with the center of the building ceiling, and then penetrates the bolts 6 and screws them to the ceiling to complete the installation of the gas collecting box 1. The screw connection method is not only stable, but also convenient for users to install and disassemble the gas collecting box 1.

[0032] Reference Figure 1 The detection assembly includes a detector 4 which is fixedly connected to the outer wall of the detection tube 2, and the detection end of which penetrates the side wall of the detection tube 2 and extends into the inner cavity of the detection tube 2. The detector 4 includes a catalytic combustion type combustible gas detection alarm and an electrochemical type toxic gas detection alarm, which can detect combustible gas, steam and various toxic organic compounds in the room.

[0033] Reference Figure 2 The air suction assembly includes an exhaust hood 7 fixedly connected to the side wall of the air collecting box 1 and connected to the inner cavity of the air collecting box 1. A servo motor 8 with a diameter smaller than the inner diameter of the exhaust hood 7 is provided in the inner cavity of the exhaust hood 7. The circumference of the servo motor 8 is fixed to the inner wall of the exhaust hood 7 through a connecting rod 10. A fan blade 9 is fixedly connected to the output end of the servo motor 8. When the servo motor 8 is started, it can drive the fan blade 9 to rotate at a high speed in the inner cavity of the exhaust hood 7, so that negative pressure is generated inside the exhaust hood 7, and under the action of the negative pressure, the air at the detection position is discharged into the detection tube 2 through the air inlet 13 and the exhaust pipe 12 for detection.

[0034] Reference Figure 3 A threaded hole is provided at one end of the exhaust hood 7 away from the air collecting box 1, and a joint 11 is fixedly connected to the open end of the exhaust pipe 12, and the exhaust pipe 12 is screwed to the threaded hole through the joint 11. The joint 11 and the threaded hole are provided to screw the exhaust pipe 12 to the exhaust hood 7, and the screw connection is not only convenient for installing and disassembling the exhaust pipe 12, but also can make the connection between the exhaust pipe 12 and the exhaust hood 7 better sealed.

[0035] Reference Figure 1 The fixing member includes a plurality of U-shaped buckles 14 sleeved on the outer surface of the exhaust pipe 12, and the plurality of buckles 14 are evenly distributed along the length direction of the exhaust pipe 12. When in use, the user can arrange the exhaust pipe 12 along the wall of the building, and fix the exhaust pipe 12 on the wall of the building through the buckles 14, so that the arrangement of the exhaust pipe 12 is more beautiful.

[0036] Reference Figure 3 A buzzer 15 is fixedly connected to the bottom wall of the gas collecting box 1, and the control device is a programmable controller 16 fixedly connected to the outer wall of the detection tube 2. The servo motor 8 and the buzzer 15 are both electrically connected to the programmable controller 16. The programmable controller 16 is used to control the multiple servo motors 8 to start alternately. At the same time, when the detector 4 detects the presence of harmful gas leakage, the programmable controller 16 can control the buzzer 15 to start and generate an alarm sound to alarm.

[0037] The implementation principle of the present application is: when in use, the user first fixes the air collecting box 1 to the indoor ceiling through the mounting plate 5 and the bolts 6, and then screws one end of the exhaust pipe 12 to the exhaust hood 7 through the joint 11, and fixes the positions of multiple exhaust pipes 12 with air inlets 13 along the building wall at positions where harmful gas leakage may exist in the indoor environment. At this time, the servo motor 8 can be started alternately to drive the fan blades 9 to rotate at high speed in the inner cavity of the exhaust hood 7, so that negative pressure is generated inside the exhaust hood 7, and under the action of negative pressure, the air at multiple detection positions is discharged into the detection tube 2 through the air inlet 13 and the exhaust pipe 12 in turn for detection, thereby avoiding the existing method as much as possible. In an indoor environment with a large space and multiple harmful gas leakage points that may occur, in order to ensure that leakage can be detected in time, it is often necessary to install early warning devices at multiple positions, which greatly increases the detection cost.
