Description

Technical Field

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

[0002] Gases are one of the most common basic substances in nature. They can be composed of a single atom or a single element, or they can be composed of compound molecules composed of multiple elements. Unlike liquids and solids, gases are colorless and odorless, have no fixed volume, and can move freely. Therefore, people need devices to assist in the detection when conducting gas environment testing.

[0003] Currently, conventional gas environment detection devices mostly use pumps to draw gas to the detection probe, which makes it difficult to quantify the air volume. Furthermore, during the gas intake process, a large amount of dust is easily drawn in, which can affect the detection results. In addition, in low temperature and high humidity environments, the detection probe is prone to condensation, leading to inaccurate detection results. Moreover, the detection probe is difficult to clean, making it very inconvenient to use. Therefore, we propose a gas environment detection device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a gas environment detection device that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A gas environment detection device includes a gas detector body. Detection probes are arranged on the upper surface of the gas detector body near the left and right sides. A heating mechanism is fixedly installed on the upper surface of the gas detector body corresponding to the detection probes. A sealing cylinder is threaded onto the outer surface of the heating mechanism. A piston disc is movably installed between the inner walls of the sealing cylinder. An air intake mechanism is fixedly installed on the piston disc. The air intake mechanism is connected to the output shaft of an electric telescopic rod via a connecting mechanism. The electric telescopic rod is installed on the upper inner wall of the gas detector body.

[0006] Furthermore, the front side of the gas detector body is equipped with a display screen and operation buttons.

[0007] Furthermore, the heating mechanism includes a threaded sleeve and an electric heating film. The threaded sleeve is fixedly installed on the upper surface of the gas detector body, and the electric heating film is fixedly installed on the inner wall of the threaded sleeve.

[0008] Furthermore, the inner diameter of the heating film on the inner wall of the threaded sleeve is the same as the inner diameter of the sealing cylinder.

[0009] Furthermore, the air intake mechanism includes a circular tube, a mechanical seal, a partition, an air intake hole, a filter element, and a limiting sleeve. The upper and lower sides of the circular tube are both open structures. The circular tube is installed in the piston disc through the mechanical seal. A partition is fixedly installed on the inner wall of the circular tube near the lower side, and an air intake hole is opened on the side wall of the circular tube on the upper side of the partition. The filter element is movably placed on the partition, and a limiting sleeve is threadedly installed on the upper surface of the circular tube.

[0010] Furthermore, a through hole is provided on the upper side wall of the sealing cylinder corresponding to the circular tube to allow the circular tube to pass through.

[0011] Furthermore, the connecting mechanism includes internal threads and external threads. The internal thread is provided on the lower side of the inner wall of the round tube, and the external thread is provided on the outer surface of the output shaft of the electric telescopic rod. The output shaft of the electric telescopic rod is connected to the internal thread on the inner wall of the round tube through the external thread.

[0012] Furthermore, a first groove is formed on the lower surface of the piston disc at a position corresponding to the detection probe, and a second groove is formed on the lower surface of the piston disc at a position corresponding to the electric telescopic rod.

[0013] Compared with the prior art, the present invention provides a gas environment detection device, which has the following beneficial effects: This invention uses an electric telescopic rod to move the air intake mechanism upwards, which in turn moves the piston disc upwards within the sealed cylinder. This allows for quantitative gas extraction and detection. The air intake mechanism also incorporates a dust filtration function for the incoming gas, resulting in more accurate test results. Furthermore, a heating mechanism adds a heating function to the detection probe, preventing frost formation and facilitating the disassembly and assembly of the sealed cylinder, thus making probe maintenance more convenient.

[0016] 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. Example

[0017] like Figures 1-3 As shown in the figure, a gas environment detection device according to one embodiment of the present invention includes a gas detector body 1. Detection probes 2 are arranged on the upper surface of the gas detector body 1 near the left and right sides. The detection probes include a temperature and humidity sensor, a CO2 sensor, a VOCs sensor, and a PM2.5 sensor. A heating mechanism 3 is fixedly installed on the upper surface of the gas detector body 1 corresponding to the detection probes 2. A sealing cylinder 4 is threadedly installed on the outer surface of the heating mechanism 3. A piston disc 5 is movably installed between the inner walls of the sealing cylinder 4. An air intake mechanism 6 is fixedly installed on the piston disc 5. The air intake mechanism 6 is connected to the output shaft of an electric telescopic rod 8 through a connecting mechanism 7. The electric telescopic rod 8 is electrically connected to a controller in the gas detector body 1. The electric telescopic rod 8 is installed on the upper inner wall of the gas detector body 1.

[0018] like Figure 1 As shown, in some embodiments, the front side of the gas detector body 1 is provided with a display screen 9 and operation buttons 10.

[0019] In this embodiment, the display screen 9 displays the detection results, and the operation button 10 issues commands to the gas detector body 1.

[0020] like Figure 2 As shown, in some embodiments, the heating mechanism 3 includes a threaded sleeve 301 and an electric heating film 302. The threaded sleeve 301 is fixedly installed on the upper surface of the gas detector body 1, and the electric heating film 302 is fixedly installed on the inner wall of the threaded sleeve 301.

[0021] In this embodiment, the threaded sleeve 301 is used to install the electric heating film 302, which is used to heat the inside of the threaded sleeve 301. The threaded sleeve 301 is also used to install and connect the sealing cylinder 4. The electric heating film 302 is electrically connected to the controller inside the gas detector body 1. The controller detects the temperature and humidity at the detection probe 2 through the temperature and humidity sensor in the detection probe 2. When the humidity is greater than the set value, the controller causes the electric heating film 302 to heat and dehumidify.

[0022] like Figure 2As shown, in some embodiments, the inner diameter of the electrothermal film 302 on the inner wall of the threaded sleeve 301 is the same as the inner diameter of the sealing cylinder 4.

[0023] In this embodiment, the sealing effect between the piston disc 5 and the heating film 302 is better, which is beneficial for gas extraction.

[0024] like Figure 3 As shown, in some embodiments, the air intake mechanism 6 includes a circular tube 601, a mechanical seal 602, a partition 603, an air intake hole 604, a filter element 605, and a limiting sleeve 606. The upper and lower sides of the circular tube 601 are open structures. The circular tube 601 is installed in the piston disc 5 through the mechanical seal 602. The partition 603 is fixedly installed on the inner wall of the circular tube 601 near the lower side, and the air intake hole 604 is opened on the side wall of the circular tube 601 above the partition 603. The filter element 605 is movably placed on the partition 603, and the limiting sleeve 606 is threadedly installed on the upper surface of the circular tube 601.

[0025] In this embodiment, the circular tube 601 is connected to the electric telescopic rod 8 through the connecting mechanism 7, so that the circular tube 601 can drive the piston disc 5 to move up and down through the mechanical seal 602. When the piston disc 5 moves upward, the external gas limiting sleeve 606 enters the circular tube 601, and the dust in the intake gas is filtered by the filter element 605. The filtered gas flows into the sealing cylinder 4 through the air inlet 604. When the piston disc 5 moves downward, the gas in the sealing cylinder 4 is squeezed through the air inlet 604 into the circular tube 601, and then discharged through the limiting sleeve 606.

[0026] like Figure 2 As shown, in some embodiments, the upper side wall of the sealing cylinder 4 corresponding to the circular tube 601 is provided with a through hole 11 for the circular tube 601 to pass through.

[0027] In this embodiment, the through hole 11 facilitates the vertical movement of the circular tube 601.

[0028] like Figure 3 As shown, in some embodiments, the connecting mechanism 7 includes an internal thread 701 and an external thread 702. The internal thread 701 is provided on the lower side of the inner wall of the round tube 601, and the external thread 702 is provided on the outer surface of the output shaft of the electric telescopic rod 8. The output shaft of the electric telescopic rod 8 is connected to the internal thread 701 on the inner wall of the round tube 601 through the external thread 702.

[0029] In this embodiment, the round tube 601 is rotated so that it is threaded onto the output shaft of the electric telescopic rod 8 through the internal thread 701 and the external thread 702, thereby achieving the effect of connecting the round tube 601 to the output shaft of the electric telescopic rod 8.

[0030] like Figure 2As shown, in some embodiments, a first groove 12 is formed on the lower surface of the piston disc 5 at a position corresponding to the detection probe 2, and a second groove 13 is formed on the lower surface of the piston disc 5 at a position corresponding to the electric telescopic rod 8.

[0031] In this embodiment, the first type of groove 12 meets the requirement of inserting the detection probe 2 into the piston disk 5, and the second type of groove 13 meets the requirement of inserting the electric telescopic rod 8 into the piston disk 5, while allowing gas to enter the air inlet 604.

[0032] In use, the sealing cylinder 4 is threaded onto the outer surface of the threaded sleeve 301 in the heating mechanism 3. Then, the round tube 601 in the air intake mechanism 6 is placed on the upper end of the output shaft of the electric telescopic rod 8. The round tube 601 is then rotated by hand. This rotation causes the round tube 601 to be threaded onto the output shaft of the electric telescopic rod 8 via the internal thread 701 and external thread 702 in the connecting mechanism 7, thus connecting the round tube 601 to the output shaft of the electric telescopic rod 8. When air extraction is required, the output shaft of the electric telescopic rod 8 drives the round tube 601 upwards, causing the round tube 601 to drive the piston disc 5 upwards via the mechanical seal 602. The piston disc 5 extracts air from the space between the sealing cylinder 4 and the gas detector body 1. The external gas limiting sleeve 606 enters the round tube 601. Dust in the intake gas is filtered by the filter element 605. The filtered gas then passes through the intake... The gas flows into the sealed cylinder 4 through the vent 604. The gas environment is checked by the detection probe 2. During the detection process, the controller detects the temperature and humidity at the detection probe 2 through the temperature and humidity sensor in the detection probe 2. When the humidity is greater than the set value, the controller causes the electric heating film 302 to heat and dehumidify. After the detection is completed, the output shaft of the electric telescopic rod 8 drives the piston disc 5 to move downward through the round tube 601 and the mechanical seal 602. The piston disc 5 compresses the gas in the sealed cylinder 4. The gas in the sealed cylinder 4 is compressed and enters the round tube 601 through the air inlet 604, and then is discharged through the limiting sleeve 606. This achieves the ability to quantitatively extract and detect the gas. At the same time, it adds a dust filtration function to the incoming gas, making the detection results more accurate. It also adds a heating function to the detection probe 2 to prevent frost from forming on the detection probe 2, making it easier to disassemble and assemble the sealed cylinder 4 and make the maintenance of the detection probe 2 more convenient.

[0033] In summary, this gas environment detection device can quantitatively extract and detect gases, while adding a dust filtration function to the incoming gas to make the detection results more accurate. It also adds a heating function to the detection probe 2 to prevent frost from forming on the detection probe 2 and facilitate the maintenance of the detection probe 2.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
