Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this utility model, a carbon dioxide detection device includes a housing 1. A gas chamber 2 is fixedly connected inside the housing 1. The gas chamber 2 is an important component of the sensor 11, providing energy for the interaction between carbon dioxide and infrared light. A power supply 10 is fixedly installed inside the gas chamber 2. The power supply 10 provides the necessary energy to the carbon dioxide detector. The power supply 10 is electrically connected to the sensor 11 via wires. The sensor 11 is the core component of the carbon dioxide detector and is responsible for detecting the concentration of carbon dioxide in the environment. The power supply 10 is electrically connected to an infrared detector 14 via wires. The infrared detector 14 and the sensor 11 determine the carbon dioxide concentration by measuring the absorption of infrared light of a specific wavelength. The infrared detector 14 penetrates the gas chamber 2 and extends outside the housing 1. An air intake pump 3 is fixedly installed inside the housing 1. The input end of the air intake pump 3 is fixedly connected to an air inlet pipe 4 and extends outside the housing 1. By drawing in air, the concentration information of carbon dioxide is detected. The output end of the air intake pump 3 is fixedly connected to an air outlet pipe 5 to release the drawn air and assist in the next detection step.

[0023] One end of the outlet pipe 5 is fixedly connected to a connecting rod 6. The gas drawn in by the suction pump 3 is projected into the gas chamber 2 through the cooperation of the gas head 7 and the gas chamber 8, allowing the device to detect the carbon dioxide concentration. The gas head 7 is fixedly installed at one end of the connecting rod 6. The gas chamber 2 has a gas chamber 8 on the side near the gas head 7. A perforation 9 is opened inside the gas chamber 8. A display 12 is fixedly connected to the outer surface of the outer shell 1. The display 12 is used to intuitively display the detection results, usually in the form of numbers or graphics. It helps users quickly understand the concentration of carbon dioxide in the environment, whether it exceeds the safety standard, and other information, so as to take appropriate measures. A signal processor 13 is fixedly connected to the outer surface of the outer shell 1. The signal processor 13 is responsible for processing the sensor data. The signal generated by the device 11 is converted into a readable form. It amplifies, filters, and performs analog-to-digital conversion on the output signal of the sensor 11 to improve the signal quality and readability, and ensure the accuracy of the detection results. The outer surface of the housing 1 is fixedly connected to an exhaust port 15 to discharge the gas after detection. Gas remaining in the gas chamber 2 will affect the accuracy of the detection information. One end of the exhaust port 15 passes through the housing 1 and extends into the gas chamber 2. The outer surface of the housing 1 is fixedly connected to a support leg 16 and a hook 17. It can be used both indoors and outdoors. If it is outdoors, the device can be placed through the support leg 16. If it is indoors, it can be hung on the wall through the hook 17 without taking up indoor floor space.

[0024] The working principle of this utility model is as follows: First, the air pump 3 inside the outer shell 1 draws in gas through the air inlet pipe 4. With the cooperation of the connecting rod 6 on the air outlet pipe 5 and the air head 7, the gas enters through the air chamber 8 and the perforation 9 on the gas chamber 2. Under the dual precise detection of the sensor 11 and the infrared detector 14 connected by the power supply 10 in the gas chamber 2, the data information is transmitted to the signal processor 13 and read on the display 12. The gas that has been detected is discharged through the exhaust port 15. It is convenient for indoor and outdoor use. It can be placed through the outdoor support leg 16, and can be hung on the wall indoors through the hook 17.
