Problems solved by technology

[0003] In the prior art, a single gas flow channel is mostly used for gas detection. The disadvantage is that the gas detector is basically in a fixed state during use, and such a setting will lead to the inability to detect the overall air flow in a large space environment. For accurate detection, in this case, multiple gas detectors need to be installed, and they need to be fixed, and it is troublesome to disassemble and move. Therefore, a gas detector with a larger detection range is required

Embodiment 1

[0033] Please refer to figure 1 , figure 1 Shown is a gas detector provided by this embodiment, including a housing 1, an air pump 2, a gas detection device 4, an alarm, an air outlet pipe 3, a plurality of air inlet pipes 5, and any air inlet pipe 5 telescopic hose 6; one end of any intake pipe 5 is connected to the input end of the air pump 2, and the other end of any air intake pipe 5 is connected to the shell 1; the output end of the air pump 2, the gas detection device 4, the gas outlet The pipeline 3 communicates with the shell 1 in turn, the alarm is connected with the gas detection device 4 , and one end of the telescopic hose 6 is connected with the inner wall of the intake pipeline 5 .

[0034] In some embodiments of the present invention, the gas detector in the prior art can only detect the surrounding gas in a small range, and the larger space may not be able to fully detect the gas. This design adopts the telescopic hose 6, and when a large space needs to be de...

Embodiment 2

[0036] Please refer to figure 2 , the present embodiment proposes based on the technical solution of embodiment 1, any air intake pipe 5 comprises diameter-expanding section 51 and pipe main body 52, and casing 1, diameter-expanding section 51, pipe main body 52 and air pump 2 are connected in sequence; diameter-expanding section The diameter of 51 near the end of the shell 1 decreases gradually toward the end away from the shell 1 .

[0037] In some embodiments of the present invention, the purpose of setting the diameter-expanding section 51 is mainly that when the telescopic hose 6 shrinks into the intake pipe, if the intake pipe 5 adopts a pipe with the same diameter, the user needs to move the intake pipe 5 when shrinking. The pipe 5 is plugged into the air intake pipe 5 section by section, and it is easy to get knotted when plugging inward, which causes the user to pay attention when using it, thereby causing inconvenience to the user. Therefore, in this embodiment, the ...

Embodiment 3

[0041] Please refer to figure 2 , the present embodiment is proposed based on the technical solution of the second embodiment, and the upper side wall of the pipeline main body 52 is provided with a plurality of decompression holes 53 .

[0042] In some embodiments of the present invention, after such a gas detector is used for a long time, more dust and dirt will be accumulated in the intake pipe 5, the air pump 2 and the gas detection device 4, so that the intake air The area of ​​the suction port of the pipeline 5 becomes smaller. In addition, the speed of air pump 2 transporting gas inward is inconvenient, which will easily cause the internal pressure of the intake pipe 5 to increase, causing the intake pipe 5 to expand and rupture, thereby making the detection inaccurate. Therefore, the present implementation adopts that a pressure relief hole 53 with a width of 0.05 mm is set on the pipeline main body 52. ​​Thus, under normal air pressure, because the air intake pipeli...

Abstract

The invention provides a gas detector, and relates to the technical field of gas detection devices. The gas detector comprises a shell, a sucking pump, a gas detection device, an alarm, a gas outlet pipeline, a plurality of gas inlet pipelines and a telescopic hose arranged in any gas inlet pipeline, wherein one end of any air inlet pipeline is connected with the input end of the sucking pump, and the other end of the any air inlet pipeline is connected with the shell; the output end of the sucking pump, the gas detection device, the gas outlet pipeline and the shell sequentially communicate with each other; the alarm is connected with the gas detection device; and one end of the telescopic hose is connected with the inner wall of the gas inlet pipeline. A user can stretch the telescopic hose according to the size of an environment, so detection in a larger range is achieved; and multi-point detection can be carried out in the range, so detection accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of gas detection devices, in particular to a gas detector. Background technique [0002] A gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The probe adjusts the gas sample through the gas sensor, usually including filtering out impurities and interfering gases, drying or cooling the display part of the instrument; the gas sensor is a method that converts information such as the composition and concentration of the gas into information that can be read by personnel, instruments, meters, etc. Devices that use information such as computers, gas sensors are generally classified as chemical sensors. Gas sensors include: semiconductor gas sensors, electrochemical gas sensors, catalytic combustion gas sensors, thermal conductivity gas sensors, infrared gas sensors, solid electrolyte gas sensors, etc. [0003] In the prior art, a single air flow...
