[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] An embodiment of the present invention provides a combustible gas detection probe. Figure 1 A schematic diagram of the structure of a combustible gas detection probe provided by an embodiment of the present invention is shown in FIG. Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure along the A-A' direction. Figure 1 and Figure 2The combustible gas detection probe 00 includes: a front shell 10, a probe base shell 20 and a tail shell 30.

[0030] The front shell 10 and the probe base shell 20, as well as the probe base shell 20 and the rear shell 30 are all mechanically connected by threads; the surface of the front shell 10 is provided with a through air hole 11, and the interior of the front shell 10 is provided with a gas concentration detection module 12, and the gas concentration detection module 12 is arranged opposite to the air hole 11; the interior of the rear shell 30 is provided with a temperature and humidity detection module 31, and the temperature and humidity detection module 31 is used to collect temperature and humidity data of the detection environment during the combustible gas detection process.

[0031] Specifically, the combustible gas detection probe 00 comprises three separate parts: a front housing 10, a probe base housing 20, and a rear housing 30. One end of the probe base housing 20 and the top of the rear housing 30 are both provided with matching threads, allowing the probe base housing 20 to be rotatably secured to the top of the rear housing 30 through a threaded connection. Similarly, the other end of the probe base housing 20 and the bottom of the front housing 10 are both provided with matching threads, allowing the front housing 10 to be rotatably secured to the probe base housing 20 through a threaded connection, thus forming the complete combustible gas detection probe 00.

[0032] A gas concentration detection module 12 is disposed within the front housing 10 of the combustible gas detection probe 00. The surface of the gas concentration detection module 12 is in contact with the inner wall of the top of the front housing 10. A through-hole 11 is provided in the top surface of the front housing 10, exposing the gas concentration detection module 12 to the detection environment through the hole 11. This allows the combustible gas detection probe 00 to be in the detection environment. As long as combustible gas enters the hole 11 at the top of the combustible gas detection probe 00, it can quickly contact the gas concentration detection module 12 through the hole 11 and react with it, thereby quickly detecting and analyzing the combustible gas concentration data in the environment.

[0033] However, during the combustible gas detection process, the temperature and humidity levels of the detection environment in which the gas concentration detection module 12 is located, as well as the temperature and humidity changes, will cause significant interference to the detection results obtained by analyzing the combustible gas concentration data collected by the gas concentration detection module 12, thereby resulting in poor accuracy of the detection results. Based on the above problems, a temperature and humidity detection module 31 is provided inside the tail shell 30 of the combustible gas detection probe 00 provided in an embodiment of the present invention. Exemplarily, the temperature and humidity detection module 31 may include a temperature and humidity sensor. By providing the temperature and humidity detection module 31 inside the combustible gas detection probe 00, the distance between the temperature and humidity detection module 31 and the gas concentration detection module 12 can be reduced as much as possible, so that the temperature and humidity detection module 31 can collect accurate temperature data and humidity data of the environment surrounding the gas concentration detection module 12 as much as possible. In this way, the collected temperature data and humidity data can be transmitted to the detection device, and the combustible gas concentration data collected and analyzed by the detection device in combination with the gas concentration detection module 12 can be compensated and corrected accordingly to eliminate the significant influence of the obtained combustible gas concentration data on the changes in ambient temperature and humidity, thereby effectively improving the accuracy of the combustible gas detection results.

[0034] The combustible gas detection probe provided by an embodiment of the present invention includes a front shell, a probe base shell, and a rear shell, and the front shell and the probe base shell, as well as the probe base shell and the rear shell, are fixed by mating threads for rotation to achieve mechanical connection. A gas concentration detection module is provided inside the front shell, and the surface of the gas concentration detection module is in contact with the inner wall of the front shell. A through-hole is provided on the top surface of the front shell, through which the gas concentration detection module can be exposed to the external detection environment. During the detection process, as long as combustible gas enters the pore, it can quickly contact the gas concentration detection module through the pore, achieving rapid detection of the combustible gas concentration, thereby quickly issuing an early warning based on the detection results, which is conducive to improving detection efficiency and ensuring personal safety. A temperature and humidity detection module is provided inside the rear shell, which can accurately collect temperature and humidity data of the detection environment around the gas concentration detection module, thereby performing parameter compensation and correction on the combustible gas concentration detection results, eliminating the impact of temperature and humidity changes in the detection environment on the detection results, and effectively improving the accuracy of the combustible gas detection results.

[0035] On the basis of the above embodiment, continue to refer to Figure 1 and Figure 2 Optionally, a plurality of through openings 32 are provided on the surface of the tail shell 30 .

[0036] The plurality of openings 32 are arranged in an array, and each opening 32 has a predetermined diameter D.

[0037] Specifically, the surface of the tail housing 30 is provided with a plurality of openings 32, each of which is provided through the tail housing 30 along the thickness direction of the tail housing 30. In other words, the plurality of openings 32 provided on the surface of the tail housing 30 enable communication between the interior of the tail housing 30 and the external detection environment, allowing the temperature and humidity detection module 31 provided inside the tail housing 30 to sense the temperature and humidity of the external detection environment, thereby detecting the temperature and humidity data of the detection environment where the gas concentration detection module 12 is located, and accordingly performing parameter compensation and correction on the detection results, thereby obtaining a highly accurate detection result.

[0038] On the surface of the tail housing 30, multiple openings 32 can be arranged in a specific pattern, for example, in an array. This regular arrangement of openings 32 provides the tail housing 30 with a strong support structure, protecting the internal components. The shape of the openings 32 can be customized based on actual needs and is not limited here. For example, in an embodiment of the present invention, the openings 32 can be circular, and each opening 32 has a predetermined diameter D.

[0039] Based on the above embodiments, optionally, the preset diameter D is smaller than the size of the temperature and humidity detection module 31 .

[0040] Specifically, by setting the preset diameter D of the opening 32 to be smaller than the size of the temperature and humidity detection module 31, the temperature and humidity detection module 31 can be protected inside the rear housing 30, so that the temperature and humidity detection module 31 is not directly exposed to the external environment through the opening 32. If the preset diameter D of the opening 32 is greater than or equal to the size of the temperature and humidity detection module 31, the temperature and humidity detection module 31 is easily damaged by the external environment directly through the opening 32, causing damage to the temperature and humidity detection module 31, affecting the accuracy of the temperature and humidity data collection, and further affecting the accuracy of the combustible gas detection results.

[0041] There are many options for the materials used in the various housings of the combustible gas detection probe 00, and different types of materials produce different effects. The following embodiments will specifically describe the material types and corresponding effects of the front housing 10, the probe base housing 20, and the rear housing 30.

[0042] Based on the above embodiments, optionally, the gas concentration detection module 12 includes a combustible gas semiconductor sensor.

[0043] For example, a combustible gas semiconductor sensor is used as the gas concentration detection module 12. Its detection principle can be: based on the characteristic that the conductivity of the semiconductor material changes with the gas environment, the semiconductor surface is chemically reacted or physically adsorbed with the combustible gas, resulting in a change in the conductivity of the semiconductor material, thereby indirectly reflecting the combustible gas concentration. During the detection process, the concentration of the combustible gas can be determined by applying a constant heating voltage and a measuring voltage to the combustible gas semiconductor sensor and measuring the change in the resistance value of the combustible gas semiconductor sensor. The heating voltage is applied to the combustible gas semiconductor sensor to maintain its operating temperature. Therefore, when the combustible gas detection probe 00 is in operation, the gas concentration detection module 12 provided at the front thereof will generate heat itself.

[0044] On the basis of the above embodiments, optionally, a signal conversion module is provided inside the probe base housing 20, and the signal conversion module is fixed to the top of the probe base housing 20;

[0045] The combustible gas semiconductor sensor is rotated and plugged through pins to electrically connect the combustible gas semiconductor sensor to the signal conversion module.

[0046] Specifically, the signal conversion module is provided at the top position of the probe base housing 20. While the front housing 10 is rotationally fixed to the probe base housing 20 through a threaded structure, the combustible gas semiconductor sensor fixed inside the front housing 10 can be plugged and fixed to the signal conversion module during the rotation process through the connection pins provided by itself, so as to realize the electrical connection between the combustible gas semiconductor sensor and the signal conversion module. Exemplarily, the signal conversion module can be a printed circuit board provided with a signal conversion circuit. The combustible gas semiconductor sensor is electrically connected to the signal conversion module through rotational plugging. The combustible gas concentration data signal collected by the combustible gas semiconductor sensor can be converted into an electrical signal through the signal conversion module. The electrical signal is transmitted to the detection device through the wire connected to the signal conversion module for calculation and analysis, thereby obtaining the detection result of the combustible gas concentration and issuing a rapid warning based on the detection result, which is conducive to improving the detection efficiency and ensuring the personal safety of relevant personnel. It should be noted that the signal conversion module is not shown in the accompanying drawings.

[0047] Based on the above embodiments, optionally, the tail shell 30 is made of metal material or polymer material.

[0048] Specifically, the tail shell 30 can be made of metal material or polymer material. For example, the polymer material can include plastic material. If the tail shell 30 is made of metal material, since the metal material has good thermal conductivity, during the detection process, the tail shell 30 can quickly conduct the temperature and humidity of the internal environment with the temperature and humidity of the external environment, so that the temperature and humidity detection module 31 can accurately measure the temperature data and humidity data of the external detection environment to perform parameter compensation and correction on the combustible gas concentration detection result, thereby reducing the impact of the temperature and humidity of the detection environment on the detection result and improving the accuracy of the detection result. If the tail shell 30 is made of polymer material, the tail shell 30 releases heat at a slower rate, which has a certain impact on the temperature data and humidity data of the external detection environment measured by the temperature and humidity detection module 31, which is not conducive to obtaining accurate combustible gas concentration detection results.

[0049] For example, the front shell 10 can be made of a metal material or a polymer material, which can include a plastic material. If the front shell 10 is made of a metal material, the heat generated by the gas concentration detection module 12 inside the front shell 10 can be quickly released to the outside during the detection process, reducing the impact of the heat generated by itself on the combustible gas concentration detection results, which is conducive to improving the accuracy of the detection results. If the front shell 10 is made of a polymer material, the heat generated by the gas concentration detection module 12 inside the front shell 10 cannot be quickly released during the detection process, which may affect the measurement accuracy of the temperature and humidity data by the temperature and humidity detection module 31 set inside the rear shell 30, thereby affecting the accuracy of the combustible gas concentration detection results.

[0050] For example, the probe base housing 20 can be made of a metal material or a polymer material, and the polymer material can include a plastic material. If the probe base housing 20 is made of a metal material, due to the good thermal conductivity of the metal material, during the detection process, the probe base housing 20 will quickly conduct the heat generated by the gas concentration detection module 12 itself to the temperature and humidity detection module 31 inside the tail shell 30, affecting the temperature and humidity detection module 31's measurement of the actual temperature data and humidity data of the external detection environment, thereby failing to accurately compensate and correct the detection results, causing the detection results to be less accurate under the influence of temperature and humidity. If the probe base housing 20 is made of a polymer material, due to the good thermal insulation ability of the polymer material, during the detection process, the probe base housing 20 can block the heat generated by the gas concentration detection module 12 itself, so that it will not be conducted to the temperature and humidity detection module 31 inside the tail shell 30, thereby reducing the influence of heat on the temperature and humidity detection module 31 detecting the temperature data and humidity data of the external detection environment, improving the accuracy of the temperature and humidity detection of the detection environment, and thus improving the accuracy of the detection results.

[0051] Based on the above embodiments, a feasible embodiment is that the front shell 10, the probe base shell 20 and the rear shell 30 of the combustible gas detection probe 00 are all made of metal materials. The heat generated by the front shell 10 of the combustible gas detection probe 00 will be quickly conducted through the probe base shell 20 to the temperature and humidity detection module 31 in the rear shell 30. The combustible gas detection probe 00 configured in this way can use the temperature and humidity detection module 31 to consider the influence of the detection environment temperature and humidity on the detection results during the process of detecting the combustible gas concentration, thereby improving the accuracy of the detection results to a certain extent; however, the heat generated by the combustible gas detection probe 00 itself has a greater influence on the detection of the temperature and humidity of the external detection environment, resulting in the temperature and humidity detection results being not completely true temperature data and humidity data of the detection environment. Therefore, the accuracy of the combustible gas concentration detection results can only be improved to a certain extent.

[0052] In another feasible embodiment, the front shell 10, the probe base shell 20, and the rear shell 30 of the combustible gas detection probe 00 are all made of polymer materials. Although this can effectively prevent the heat generated by the front shell 10 from being quickly transferred to the temperature and humidity detection module 31 inside the rear shell 30, the heat inside the front shell 10 and the rear shell 30 cannot be effectively released. For example, after detecting the combustible gas concentration in a detection environment with a high ambient temperature and high humidity, when the combustible gas concentration is changed to a detection environment with a low ambient temperature and low humidity, the remaining heat inside the rear shell 30 cannot be quickly released, causing the temperature and humidity detection module 31 to have a greater impact on the detection of the temperature and humidity data of the new detection environment. Although the accuracy of the combustible gas concentration detection results can be improved to a certain extent, the improvement effect is limited.

[0053] In another feasible embodiment, preferably, the front shell 10 and the rear shell 30 of the combustible gas detection probe 00 are made of metal materials, and the probe base shell 20 is made of polymer materials. In the combustible gas detection probe 00 configured in this way, the heat of the front shell 10 and the rear shell 30 can be quickly released through the metal material with good thermal conductivity, and the probe base shell 20 located between the front shell 10 and the rear shell 30 has a good thermal insulation effect, which can well block the heat generated by the gas concentration detection module 12 in the front shell 10, reduce the impact on the temperature and humidity data detected by the temperature and humidity detection module 31 in the rear shell 30, and obtain accurate temperature data and humidity data of the external detection environment, thereby effectively compensating and correcting the parameters of the detection results of the combustible gas concentration, and achieving the best effect on improving the accuracy of the combustible gas concentration detection results.

[0054] On the basis of the above embodiments, continue to refer to Figure 2Optionally, a heat insulation area is provided inside the probe base housing 20, and a heat insulation structure 21 is provided in the heat insulation area;

[0055] The heat insulation structure 21 is used to provide heat insulation between the temperature and humidity detection module 31 and the gas concentration detection module 12 .

[0056] Specifically, the probe base housing 20 is used to connect the front housing 10 and the rear housing 30. Since the gas concentration detection module 12 in the front housing 10 will generate heat and release heat during the inspection process, in order to prevent the temperature and humidity detection module 31 provided in the rear housing 30 from being easily interfered with by the heat released by the gas concentration detection module 12 when detecting the temperature and humidity data of the external detection environment, an insulation area is provided inside the probe base housing 20. By providing an insulation structure 21 in the insulation area, the insulation structure 21 is filled into the insulation area, thereby achieving heat conduction between the gas concentration detection module 12 in the front housing 10 and the temperature and humidity detection module 31 in the rear housing 30, ensuring that the temperature data and humidity data detected by the temperature and humidity detection module 31 can reflect the actual temperature and humidity conditions of the detection environment in which the combustible gas detection probe 00 is located, which is conducive to improving the accuracy of the combustible gas concentration detection results. Exemplarily, the insulation structure 21 includes insulation glue. The insulation area in the probe base housing 20 is the area filled with insulation glue. The thermal insulation glue can be thermal insulation AB glue, which is a two-component adhesive. In addition to the basic bonding function, it can also achieve properties such as thermal insulation, high temperature resistance and flame retardancy. The main components of the thermal insulation AB glue include component A and component B, wherein component A is usually epoxy resin, silicone resin or acrylic resin to provide the basic performance of the bonding substrate; component B is usually a curing agent, such as amines, acid anhydrides, etc., and component B reacts with component A to cross-link and solidify the colloid. During use, the AB glue must be prepared strictly according to a certain ratio. If the mixing is uneven, the colloid may not be fully cured or the performance may be degraded. The prepared and evenly mixed thermal insulation glue is poured into the thermal insulation area until it is completely cured, that is, a thermal insulation structure 21 is formed in the thermal insulation area, thereby blocking the heat between the gas concentration detection module 12 and the temperature and humidity detection module 31.

[0057] On the basis of the above embodiments, continue to refer to Figure 2 , Optionally, there is a preset distance d between the gas concentration detection module 12 and the temperature and humidity detection module 31;

[0058] The preset distance d ranges from 3 to 4 cm.

[0059] Specifically, there needs to be a certain distance between the setting positions of the temperature and humidity detection module 31 and the gas concentration detection module 12. Since the gas concentration detection module 12 will generate heat during the detection process, if the setting distance between the temperature and humidity detection module 31 and the gas concentration detection module 12 is too small, the temperature and humidity detection module 31 will be interfered with by the heat of the combustible gas detection probe 00 itself when detecting the temperature and humidity data of the external detection environment, making the collected data of the temperature and humidity conditions of the detection environment inaccurate, thereby affecting the accuracy of the combustible gas concentration detection results, and further leading to false alarms and the like. Therefore, the distance between the gas concentration detection module 12 and the temperature and humidity detection module 31 can be set to a preset distance d, and the preset distance d includes the length of the probe base housing 20. Preferably, the preset distance d is 3 to 4 cm. If the preset distance d is too small, the heat insulation structure 21 in the probe base housing 20 alone will not be able to effectively block the heat released by the gas concentration detection module 12, affecting the accuracy of the temperature and humidity data collected by the temperature and humidity detection module 31. This will make it impossible to accurately compensate and correct parameters, which is not conducive to improving the accuracy of the combustible gas concentration detection results. If the preset distance d is too large, although it can effectively block the heat between the gas concentration detection module 12 and the temperature and humidity detection module 31, it will increase the volume of the combustible gas detection probe 00, limiting the range of combustible gas concentration detection.

[0060] An embodiment of the present invention also provides a combustible gas detection device. Figure 3 Schematic diagram of a combustible gas detection device provided by an embodiment of the present invention. Figure 3 The combustible gas detection device 000 comprises: a unit 01 and a combustible gas detection probe 00 as provided in any of the above embodiments;

[0061] The combustible gas detection probe 00 is connected to the machine 01 via the pipeline 02.

[0062] Specifically, the combustible gas detection probe 00 is connected to the main unit 01 via a pipe 02 of a certain length. During the detection process, the combustible gas detection probe 00 can be extended into a narrow detection position through the pipe 02, thereby detecting the combustible gas concentration in the narrow area. Furthermore, during the detection process, the gas concentration detection module 12 transmits the measured gas concentration data to the main unit 01 via the pipe 02, and the temperature and humidity detection module 31 transmits the collected external detection environment temperature and humidity data to the main unit 01 via the pipe 02. The main unit 01 performs parameter compensation and correction on the gas concentration data based on the temperature and humidity data, thereby reducing the impact of drastic changes in the temperature and humidity of the detection environment on the detection results of the combustible gas concentration, which helps to improve the accuracy of the detection results.

[0063] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
