Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a mobile laboratory gas detection sampler. Background Technology

[0002] Gas is a fundamental state of matter, and together with solid and liquid, it constitutes the three common states of matter. It has no fixed shape or volume and can fill an entire container. Its molecules are relatively far apart and have weak interaction forces, allowing them to move freely and quickly. When detecting gases, conventional equipment cannot effectively detect different types of gases due to the different types of gases, which affects the detection results.

[0003] Existing technology CN212207291U discloses a laboratory gas leak detection device, including a power cord, switch, exhaust fan, conduit, gas detection chamber, chamber body, gas sensor, motor, second rotating rod, track, first rotating rod, rotating wheel, connecting rod, microcontroller, indicator light, and buzzer alarm. When the power cord is connected and the switch is turned on, the exhaust fan starts working, introducing gas into the chamber body of the gas detection chamber through the conduit. The gas comes into contact with gas sensors of different types. At the same time, the motor starts, driving the second rotating rod to rotate. Through the track and the first rotating rod, the rotating wheel and the gas sensor fixed to the rotating wheel via the connecting rod rotate, increasing the contact opportunity between the gas sensor and the extracted gas, thereby increasing the sensitivity of the device. When the gas sensor detects laboratory leak gas in the extracted gas, the gas sensor transmits a signal to the microcontroller. The microcontroller controls the indicator light and buzzer alarm to sound an alarm, thereby improving the gas detection effect.

[0004] In normal use, existing technologies make it inconvenient to sample and preserve different types of gases during the detection process, thus affecting the accuracy of the gas detection results and impacting the detection performance of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a mobile laboratory gas detector sampler, which solves the problem that in the process of detecting different types of gases, the existing equipment is inconvenient to sample and preserve different types of gases to ensure the accuracy of gas detection results, thus affecting the detection effect of the equipment.

[0006] To achieve the above objectives, this utility model provides a mobile laboratory gas detection sampler, including a housing and structural components. The structural components include a fan, a conduit, a valve body, a sampling bottle, a needle, a frame, a block, a push button, a slide rod, a first spring, a detection component, and a driving component. The frame is fixedly installed on one side of the housing, the block is slidably installed on the side of the frame away from the housing, the sampling bottle is detachably connected to the frame, the conduit communicates with the housing, the output end of the fan is connected to the conduit, the detection component is connected to the housing, the driving component is connected to the frame, the push button is slidably connected to the frame and connected to the driving component, the input end of the valve body communicates with the conduit via a pipe, the needle is fixedly connected to the frame and communicates with the output end of the valve body via a pipe, the slide rod is fixedly connected to the frame and slidably connected to the block, one end of the first spring is connected to the frame, and the other end of the first spring is connected to the block.

[0007] The driving component includes a frame, a slider, and a moving part. The frame is fixedly connected to the frame and slidably connected to the button. The slider is slidably connected to the frame and fixedly connected to the button. The moving part is connected to the frame, the slider, and the frame.

[0008] The movable component includes a movable rod and a second spring. The movable rod is fixedly connected to the frame and the outer frame, and is slidably connected to the slider. One end of the second spring is connected to the frame, and the other end of the second spring is connected to the slider.

[0009] The detection component includes a gas sensor, a mounting block, and a rotating component. The mounting block is rotatably connected to the housing and is located on the side of the housing away from the conduit. The rotating component is connected to the housing and to the mounting block. The gas sensor is fixedly connected to the mounting block and is located on the side of the mounting block away from the housing.

[0010] The rotating component includes a belt, a main wheel, and a rotating motor. The rotating motor is fixedly connected to the housing and located on the side of the housing away from the mounting block. The main wheel is connected to the output shaft of the rotating motor. One end of the belt is sleeved on the main wheel, and the other end of the belt is sleeved on the mounting block.

[0011] This utility model discloses a mobile laboratory gas detection sampler. A fan draws gas into the housing. A rotating motor drives a main wheel to rotate, which in turn drives a belt to rotate a mounting block. As the mounting block rotates, it causes a gas sensor to rotate inside the housing, contacting the gas and transmitting data to a computer for gas detection. Pressing a button moves a slider on a sliding rod, compressing a second spring. This causes the button to press against the block, resulting in the two blocks moving in opposite directions. The first spring is compressed, and the sample is then taken. The bottle is inserted into the frame, and the needle is inserted into the rubber layer of the sampling bottle. The button is released, and the second spring drives the slider to move on the slide rod, causing the button to rise and separate from the block. The first spring then drives the block to move on the slide rod, causing the block to abut against both sides of the sampling bottle. The sampling bottle is then installed on the frame. The valve is opened, and gas enters the sampling bottle through the conduit and the needle, thus sampling and storing the gas in the sampling bottle. This allows the device to easily sample and store different types of gases, ensuring the accuracy of gas detection results and improving the device's detection effect. Attached Figure Description
