Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide detection technology, specifically a carbon dioxide concentration detection device. Background Technology

[0002] Carbon dioxide, a carbon oxide compound, is a colorless and odorless gas with a slightly acidic smell at room temperature and pressure. It can be used as a preservative, refrigerant, and fire extinguisher, and is also an important raw material in the chemical industry.

[0003] Carbon dioxide is typically stored in cylinders after production. To monitor its concentration, a carbon dioxide concentration detector is usually used during the production process. However, during storage, carbon dioxide can be contaminated by other gases, affecting its concentration. Furthermore, once stored in cylinders, it's inconvenient to use a carbon dioxide concentration detector to monitor the carbon dioxide levels inside. Therefore, we propose a carbon dioxide concentration detection device. Utility Model Content

[0004] To address the shortcomings of existing carbon dioxide detectors that are inconvenient for detecting carbon dioxide in carbon dioxide cylinders, this invention provides a carbon dioxide concentration detection device that can be connected to the outlet of a carbon dioxide cylinder to detect the carbon dioxide inside, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a carbon dioxide concentration detection device, including a connecting sleeve, which is fitted onto the outlet of a carbon dioxide cylinder and threadedly engaged with the outlet.

[0006] One end of the connecting sleeve is connected to a handle. The handle is hollow and connected to the connecting sleeve. One end of the handle is rotatably connected to a first pipe connector. A gas supply pipe is connected to the first pipe connector. The other end of the gas supply pipe is connected to a carbon dioxide detector through a second pipe connector.

[0007] Optionally, the inner diameter of the handle is smaller than the inner diameter of the connecting sleeve, forming a stepped structure between them, and a sealing gasket is installed on the stepped structure, which is sealed to the end of the carbon dioxide cylinder outlet.

[0008] Optionally, the carbon dioxide detector includes a housing, an internal detection chamber, a second pipe connector, and an exhaust pipe installed on one side of the detection chamber, with one end of the exhaust pipe extending outside the housing.

[0009] A carbon dioxide concentration sensor is installed at the bottom of the detection chamber, a control motherboard is installed inside the housing, and a display screen is installed on the outer side of the housing. The control motherboard is connected to the carbon dioxide concentration sensor and the display screen via wires.

[0010] Optionally, a first valve is installed on the gas supply pipe, and a second valve is installed at one end of the exhaust pipe, with the second valve fixed to the housing.

[0012] Optionally, a receiving groove is provided on the side of the handle, and a lever is rotatably connected in the receiving groove. The lever is fixed in the receiving groove by magnetic attraction. The side of the lever is arc-shaped and flush with the side of the handle, and one end of the lever and the end of the receiving groove are provided with notches.

[0013] Optionally, the rotation angle of the lever is A, where 0°≤A≤90°.

[0014] Compared with the prior art, this utility model allows the gas in the carbon dioxide cylinder to be transported to the detection chamber through the gas delivery pipe by connecting the connecting sleeve to the gas outlet of the carbon dioxide cylinder during use. The carbon dioxide concentration sensor then detects the carbon dioxide in the detection chamber, making the detection convenient and accurate, thus improving the effectiveness of use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 Figures 1 to 5 This utility model provides a technical solution: a carbon dioxide concentration detection device, including a connecting sleeve 1, such as... Figure 5 As shown, the connecting sleeve 1 is fitted onto the gas outlet of the carbon dioxide cylinder and is threaded into the gas outlet.

[0023] like Figure 3 As shown, one end of the connecting sleeve 1 is connected to a handle 2. The handle 2 is a hollow structure and communicates with the connecting sleeve 1. The inner diameter of the handle 2 is smaller than the inner diameter of the connecting sleeve 1, as shown below. Figure 4 As shown, a stepped structure is formed between the two, and a sealing gasket 16 is installed on the stepped structure. The sealing gasket 16 is sealed to the end of the carbon dioxide cylinder outlet. During connection, the sealing gasket 16 ensures a sealed fit between the connecting sleeve 1 and the carbon dioxide cylinder outlet, thus preventing carbon dioxide leakage from the connection between the connecting sleeve 1 and the outlet when the carbon dioxide concentration is detected.

[0024] One end of the handle 2 is rotatably connected to the first pipe connector 5. It should be noted that the connection between the first pipe connector 5 and the handle 2 is sealed by a sealing ring, which can prevent carbon dioxide gas from leaking from the connection between the handle 2 and the first pipe connector 5.

[0025] like Figure 1 and Figure 2 As shown, a gas supply pipe 6 is connected to the first pipe connector 5, and the other end of the gas supply pipe 6 is connected to a carbon dioxide detector via a second pipe connector 7. The carbon dioxide detector includes a housing 9, and a detection chamber 13 is provided inside the housing 9. The detection chamber 13 is connected to the gas supply pipe 6 via the second pipe connector 7, and an exhaust pipe 11 is installed on one side of the detection chamber 13. One end of the exhaust pipe 11 extends to the outside of the housing 9. A first valve 8 is installed on the gas supply pipe 6, and a second valve 10 is installed on one end of the exhaust pipe 11. The second valve 10 is fixed to the housing 9. To improve detection accuracy, carbon dioxide can be emitted for a preset time during detection. When the carbon dioxide is delivered to the detection chamber 13 through the gas supply pipe 6, the air in the detection chamber 13 can be discharged through the exhaust pipe 11, thus filling the detection chamber 13 with carbon dioxide. After the carbon dioxide gas is introduced into the detection chamber 13 for a preset time, the first valve 8 and the second valve 10 can be closed to isolate the detection chamber 13 from the external environment. This can avoid the detection results being affected by the external environment, making the detection more accurate.

[0026] like Figure 2 As shown, a carbon dioxide concentration sensor 14 is installed at the bottom of the detection chamber 13, a control motherboard 15 is installed inside the housing 9, and a display screen 12 is installed on the outer side of the housing 9. The control motherboard 15 is connected to the carbon dioxide concentration sensor 14 and the display screen 12 via wires. The control motherboard 15 is either a PCB circuit board or a microcontroller circuit board. During detection, the carbon dioxide concentration sensor 14 can detect the concentration of carbon dioxide gas filled into the detection chamber 13 and transmit the detection data to the control motherboard 15. The control motherboard 15 then transmits the detection result to the display screen 12 for easy observation by the staff.

[0027] Specifically, in use, the operator aligns the connecting sleeve 1 with the outlet of the carbon dioxide cylinder and rotates the handle 2. The handle 2 causes the connecting sleeve 1 to rotate, so that the connecting sleeve 1 is fitted onto the outlet (e.g., Figure 5 (As shown), then open the carbon dioxide cylinder valve, and the carbon dioxide in the carbon dioxide cylinder is transported to the detection chamber 13 along the gas supply pipe 6. The air in the detection chamber 13 is discharged from the exhaust pipe 11. After the preset ventilation time, close the first valve 8 and the second valve 10. The carbon dioxide concentration sensor 14 detects the concentration of carbon dioxide in the detection chamber 13 and transmits the detection result to the control main board 15. The control main board 15 then displays the detection result on the display screen 12, thus completing the detection of carbon dioxide concentration.

[0028] Furthermore, such as Figure 2 As shown, a rechargeable battery 17 is installed inside the housing 9, and the rechargeable battery 17 is connected to the control motherboard 15 via wires. The rechargeable battery 17 provides power to the control motherboard 15, the carbon dioxide concentration sensor 14, and the display screen 12, ensuring that the control motherboard 15, the carbon dioxide concentration sensor 14, and the display screen 12 can work normally.

[0029] It should be noted that a charging port can also be provided at the bottom of the housing 9. The charging port is connected to the control motherboard 15 through a wire, so that the rechargeable battery 17 can be charged when it is out of power, thus improving the performance.

[0030] Furthermore, such as Figure 3As shown, a receiving groove 3 is provided on the side of the handle 2. A lever 4 is rotatably connected to the receiving groove 3. The lever 4 is fixed in the receiving groove 3 by magnetic attraction. That is, magnets are embedded on the opposite surfaces of the lever 4 and the receiving groove 3. When the lever 4 is placed in the receiving groove 3, they attract each other. The side of the lever 4 is arc-shaped and flush with the side of the handle 2. One end of the lever 4 and the end of the receiving groove 3 are provided with notches. When rotating the lever 4, the operator can insert their finger into the notch at the end of the lever 4 and the end of the receiving groove 3, which makes it easy to remove the end of the lever 4 from the receiving groove 3.

[0031] The lever 4 rotates at an angle A, where 0° ≤ A ≤ 90°. When the lever 4 rotates 90°, one end of the lever 4 extends outside the receiving groove 3 and is perpendicular to the handle 2. During the process of connecting the connecting sleeve 1 to the carbon dioxide cylinder outlet, in order to ensure a tight connection between the connecting sleeve 1 and the outlet, as follows... Figure 5 As shown, the operator can rotate lever 4 to a position perpendicular to handle 2 and away from the carbon dioxide cylinder. Then, the operator holds lever 4 and applies force to it to rotate handle 2. This increases the lever arm of rotating handle 2, thereby tightly connecting connecting sleeve 1 to the gas outlet.
