Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to an environmental gas detector. Background Art

[0002] The environment is closely related to our lives. In the process of environmental testing, testing the air composition and air quality in the environment is an important part of the testing. In the traditional environmental testing process, it is necessary to set up a testing bracket in the environment and install the environmental testing instrument on the testing bracket, which is a large workload and wastes a lot of manpower and material resources, and is very troublesome to implement.

[0003] There is already a portable gas detector on the market, which can be carried directly to the target environment by hand to detect the air in the target environment. However, with the development of technology, detection instruments are becoming more and more sophisticated. In order to adapt to different environments and better detect environmental gases, various detection instruments for plateau terrain, plain terrain, and sea are specifically differentiated in the existing environmental detection instruments. However, the above-mentioned portable gas detectors are all all-in-one machines, which only have the gas detection function of a single environment. It is impossible to reasonably select different detection bodies according to the environment, resulting in limited detection capabilities. If you want to accurately detect gases in different environments, you need to carry several different types of detectors, which undoubtedly greatly increases the amount of work that staff have to carry.

DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] The environmental gas detector provided by the embodiment of the present invention is now described in conjunction with the accompanying drawings.

[0044] See also Figures 1 to 5 An environmental gas detector includes a gas detection module 100 and a control module 200. The gas detection module 100 is provided with a plug board 110, and the plug board 110 is provided with an electrical plug interface 111. The electrical plug interface 111 is used to electrically connect the control module 200 so that the control module 200 and the gas detection module 100 form a complete detector.

[0045] Among them, the control module 200 includes a controller 210, an electrical connection seat 220, a buckle plate 230 and a positioning mechanism 240. The controller 210 is used to control the operation of the entire detector. The electrical connection seat 220 is set on the controller 210, and the buckle plate 230 is rotatably set on the electrical connection seat 220. The middle part of the buckle plate 230 is provided with an electrical contact strip 231 for plugging into the electrical plug interface 111. The electrical contact strip 231 has a plurality of electrical contact sheets arranged in a straight line along its length direction. The electrical plug interface 111 is provided with a metal sheet matching each electrical contact sheet, so that the electrical contact strip 231 is electrically connected to the gas detection module 100 through the metal sheet after being plugged into the plug-in component 242.

[0046] The positioning mechanism 240 includes an elastic member 241 and a plug-in member 242 movably arranged on the electrical connection seat 220. The electrical connection seat 220 is provided with a plug-in through hole 221. The plug-in member 242 is inserted into the plug-in through hole 221 and can move on the plug-in through hole 221. The elastic member 241 is connected between the plug-in member 242 and the electrical connection seat 220, and pushes one end of the plug-in member 242 to abut against the outer edge of the snap-on plate 230, so that during the rotation of the snap-on plate 230, the abutting end of the plug-in member 242 always abuts against the snap-on plate 230. The outer edge of the snap-on plate 230 is provided with at least one snap-on hole 232 for the plug-in member 242 to snap into, and the snap-on hole 232 is located on the abutting track of the abutting end of the plug-in member 242.

[0047] The installation process of this environmental gas detector is as follows: align and plug the electrical contact strip 231 on the control module 200 into the electrical socket 111, so that the control module 200 is electrically connected to the gas detection module 100. At this time, the control module 200 can be relatively rotated through the snap-on plate 230 on the electrical connection seat 220 to rotate the position of the entire control module 200. When it is rotated to a suitable position, the plug-in piece 242 resting on the outer wall of the snap-on plate 230 is snapped into the snap-on hole 232 under the action of the elastic piece 241, thereby fixing the control module 200 on the gas detection module 100 and completing the installation.

[0048] During disassembly, the plug 242 is pulled out, and the plug 242 no longer locks the control module 200, and the control module 200 is moved away from the gas detection module 100, so that the electrical contact strip 231 is separated from the electrical plug interface 111, and the disassembly is completed.

[0049] Compared with the prior art, the present invention adopts a split structure, splitting the environmental gas detector into a gas detection module 100 and a control module 200, so that the control module 200 can adapt to different gas detection modules 100 to achieve different gas detection functions, thereby solving the problem that the current gas detection function is single and cannot meet the requirements of environmental gas detection; and the gas detection module 100 and the control module 200 are flexibly connected, and the electrical contact strip 231 can continue to be connected by plugging and unplugging after being inserted into the electrical plug interface 111 by rotating the buckle plate 230. The cooperation between the component 242 and the snap-on hole 232 fixes the positional relationship between the controller 210 and the snap-on plate 230, thereby fixing the positions of the gas detection module 100 and the control module 200 to form a fixed whole. The assembly position between the gas detection module 100 and the control module 200 can be established according to usage requirements, and the use is flexible; at the same time, when the control module 200 is rotated to the appropriate position relative to the gas detection module 100, the elastic component 241 pushes the plug-in component 242 to automatically snap into the corresponding snap-on hole 232, thereby improving the assembly efficiency of the detection module on the gas detection module 100.

[0050] In one embodiment of the present invention, at least two positioning posts 233 are provided on the buckle plate 230, and at least two positioning holes 112 are provided on the plug board 110. The position of each positioning post 233 on the buckle plate 230 corresponds to the position of each positioning hole 112 on the plug board 110. When the positioning posts 233 are inserted into the corresponding positioning holes 112, the electrical plug interface 111 is aligned with the insertion direction of the electrical contact strip 231. At the same time, the positioning posts 233 guide the electrical contact strip 231 to be inserted into the electrical plug interface 111 during the further penetration process, so as to facilitate the assembly and connection of the control module 200 on the gas detection component 150, and avoid damage to the electrical contact strip 231 or the electrical plug interface 111 due to inaccurate plugging direction when the electrical contact strip 231 is directly plugged into the electrical plug interface 111. At the same time, the pairing of the positioning posts 233 and the positioning holes 112 can also enhance the lateral bearing capacity when the control module 200 is connected to the gas detection module 100, and improve the structural stability of the detachable whole.

[0051] Further, see Figure 6 and Figure 7 There are two positioning holes 112 and they are arranged on opposite sides of the electrical plug interface 111. A first elastic blocking piece 113 and a second elastic blocking piece 114 are arranged in the plug board 110. The first elastic blocking piece 113 and the second elastic blocking piece 114 are engaged with each other on the inner side of the electrical plug interface 111, and the engaging edges of the first elastic blocking piece 113 and the second elastic blocking piece 114 are closed in the electrical plug interface 111. After the positioning column 233 is inserted into the positioning hole 112, the positioning column 233 located on the same side of the first elastic blocking piece 113 pushes the first elastic blocking piece 113 to make the first elastic blocking piece 113 disengage from the electrical plug interface 111, and the positioning column 233 located on the same side of the second elastic blocking piece 114 pushes the second elastic blocking piece 114 to make the second elastic blocking piece 114 disengage from the electrical plug interface 111. As a result, the first elastic blocking piece 113 and the second elastic blocking piece 114 are no longer closed on the electrical plug interface 111, and the electrical plug interface 111 is opened so that the electrical contact strip 231 can be connected. By providing the structure of the first elastic baffle 113 and the second elastic baffle 114, dust can be effectively prevented from entering the interior of the electrical plug interface 111, and the impact of the external environment on the electrical plug interface 111 can be significantly reduced, thereby extending the service life of the electrical plug interface 111, and utilizing the linkage relationship between the positioning column 233 and the positioning hole 112 to improve the assembly smoothness of the control module 200 and the gas detection module 100.

[0052] In this embodiment, the first elastic baffle 113 and the second elastic baffle 114 are both rotatably arranged in the plug board 110, and the rotational connection between the plug board 110 and the first elastic baffle 113 and the second elastic baffle 114 is provided with a reset torsion spring 115. Specifically, the plug board 110 is fixedly connected to the gas detection module 100, and an internal cavity is formed between the plug board 110 and the gas detection module 100. The first elastic baffle 113 and the second elastic baffle 114 are relatively hinged on opposite sides of the internal cavity, and the first elastic baffle 113 and the second elastic baffle 114 are close to each other and engaged under the action of the reset torsion spring 115, and the engaged position is exactly located in the middle of the electrical plug interface 111. By means of the rotation setting mode and the setting of the reset torsion spring 115, after the control module 200 is separated from the gas detection module 100, the reset torsion spring 115 uses its elastic potential energy to push the first elastic baffle 113 and the second elastic baffle 114 to reset and reclose the electrical plug interface 111. At the same time, the force exerted by the reset torsion spring 115 on the first elastic baffle 113 and the second elastic baffle 114 can further push back the positioning column 233, so that the positioning column 233 is separated from the positioning hole 112, so as to facilitate the separation of the control module 200 from the gas detection module 100.

[0053] Further, see Figures 8 to 12 , and also includes a snap-fit ​​fixing component, which includes a first snap-fit ​​mechanism 310 arranged on the control module 200 and a second snap-fit ​​mechanism 320 arranged on the gas detection module 100, and the first snap-fit ​​mechanism 310 cooperates with the second snap-fit ​​mechanism 320 to better fix the control module 200 on the gas detection module 100.

[0054] On the one hand, see Figure 1 and Figure 8The bottom of the control module 200 is provided with a buckle extension opening 260, and the first buckle mechanism 310 includes a first buckle block 311, a first sliding cover 312 and a push block 313. The first buckle block 311 is elastically arranged on the buckle extension opening 260, and a reset tension spring is arranged between the first buckle block 311 and the inside of the control module 200. One end of the reset tension spring is buckled on the buckle column 311-1 of the first buckle block 311, and the other end is buckled on the inner side of the shell of the control module 200, which is used to pull the first buckle block 311 to reset and retract to the buckle extension opening 260. Among them, the middle part of the first buckle block 311 is provided with an inclined guide groove 311-2, and the end of the push block 313 has a push inclined surface 313-1 matched with the inclined guide groove 311-2, and the first buckle block 311 is pushed to move toward the bottom of the control module 200 through the push inclined surface 313-1, and overcomes the tension of the reset tension spring to extend to the buckle extension opening 260. The first sliding cover 312 is arranged on the buckle extension opening 260, and is provided with a force-bearing protrusion 312-1. The force-bearing protrusion 312-1 has an inclined guide surface 312-2. The side surface of the push block 313 has an inclined pushing portion 313-2, and the inclined pushing portion 313-2 is pressed against the inclined guide surface 312-2. When the push block 313 moves in the direction of pushing the first buckle block 311, that is, the X direction, the inclined pushing portion 313-2 pushes the first sliding cover 312 to move along the Y direction through the inclined guide surface 312-2, so that the first sliding cover 312 opens the buckle extension opening 260, and at the same time makes the first buckle block 311 move along the Z direction and be able to extend out of the buckle extension opening 260.

[0055] The extension process of the first rebate mechanism 310 is as follows: the push block 313 moves in the X direction, and the oblique push portion 313-2 on the side pushes the first sliding cover 312 to move along the Y direction and open the buckle extension opening 260. At the same time, the push inclined surface 313-1 at its end uses the oblique guide groove 311-2 to push the first buckle block 311 to move along the Z direction and finally extend to the buckle extension opening 260 to cooperate with the second rebate mechanism 320.

[0056] In addition, a return spring is provided between the first slide cover 312 and the housing of the first slide cover 312, and the return spring is used to pull the first slide cover 312 to return to the opposite direction of Y. When the return spring pulls the first buckle block 311 to retract and return, the push block 313 is pushed back, and the first slide cover 312 recloses the buckle extension opening 260 under the action of the return spring, so as to achieve the purpose of protecting the first buckle mechanism 310. The other end of the push block 313 away from the push inclined surface 313-1 extends to the outside of the control module 200, and the end has a pressing portion 313-3, and a human hand pushes the push block 313 to move along the X direction through the pressing portion 313-3.

[0057] On the other hand, see Figure 2 , Fig. 9 , Fig.10 , Fig.11 and Fig.12The gas detection module 100 has a snap-on docking port 160 on its end face, and the second snapback mechanism 320 includes a second sliding cover 321, an unlocking column 322 and an intermediate block 323. The unlocking column 322 is telescopically arranged at the bottom of the internal cavity formed between the plug-in board 110 and the gas detection module 100, that is, below the first elastic baffle 113 and / or the second elastic baffle 114, and the intermediate block 323 is hinged to the outer shell of the gas detection module 100 and is located below the unlocking column 322. The bottom of the unlocking column 322 has an inverted cone 322-1, and the intermediate block 323 has a force-bearing inclined surface 323-1 that matches the inverted cone surface of the inverted cone 322-1. Among them, an elastic reset member is provided between the unlocking column 322 and the gas detection module 100, and the elastic reset member is used to reset the unlocking column 322 in the opposite direction of U and protrude on the internal cavity, and the protruding end of the unlocking column 322 in the internal cavity is used for the first elastic baffle 113 and the second elastic baffle 114 to push and retract. The second sliding cover 321 is provided on the buckle docking interface 160, and the middle block 323 is connected to the second sliding cover 321 through a connecting line 324, and a fixed pulley 170 is also provided on the housing of the gas detection module 100. The connecting line 324 extends from the middle block 323 and then bypasses the fixed pulley 170 and is connected to the second sliding cover 321, so that when the middle block 323 rotates in the W direction, the second sliding cover 321 is pulled to move in the V direction, thereby opening the buckle docking interface 160, so that the lower buckle can extend into the buckle docking interface 160.

[0058] Specifically, a second buckle block 325 is slidably arranged in the buckle docking port 160, a fixed block 180 is provided on the outer shell of the gas detection module 100, and a reel tension spring 326 is provided between the fixed block 180 and the second buckle block 325, which can pull the second buckle block 325 to reset, and when the first buckle block 311 is extended into the buckle docking port 160, the second buckle block 325 is fastened with the first buckle block 311 in the N direction.

[0059] In addition, the upper end surface of the second buckle block 325 is a lower guide surface, and the lower end surface of the first buckle block 311 is a lower guide surface. The push structure of the upper guide surface and the lower guide surface allows the first buckle block 311 to be smoothly buckled with the second buckle block 325. The second buckle block 325 has a pull handle 325-1 extending to the outside of the gas detection module 100. When the first buckle block 311 and the second buckle block 325 are buckled, the pull handle 325-1 pulls the second buckle block 325 to move in the opposite direction of N, thereby unlocking the first buckle block 311.

[0060] In combination with the above structure, during the fixed assembly process of the control module 200 of this embodiment, after the buckle plate 230 is docked with the plug board 110, the first elastic baffle 113 and the second elastic baffle 114 push down the unlocking column 322, and the unlocking column 322 pushes the middle block 323, and the second sliding cover 321 is linked to open the buckle docking interface 160 through the connecting line 324.

In a structural manner similar to a threaded connection, the buckle edge 116 is finally clamped and fastened to the buckle piece 223, thereby achieving the position fixation between the control module 200 and the gas detection module 100. On the basis of the above structure, the plug-in fixation of the plug-in member 242 is added to further enhance the installation stability of the control module 200 and the gas detection module 100. In this embodiment, the gas detection module 100 also includes a plug cover 120, which is detachably buckled on the plug board 110 and is used to cover the electrical plug interface 111 to protect the connection part between the gas detection module 100 and the control module 200.

The limiting groove 224 limits the rotation range of the buckle plate 230 on the electrical connection seat 220 through the limiting protrusion 234, preventing the buckle plate 230 from rotating too much and affecting the electrical connection with the controller 210.

[0064] In another embodiment of the present invention, the gas detection module 100 includes a housing 130, a suction pump 140 and a gas detection assembly 150, the housing 130 has a suction port 131, the suction pump 140 has a suction end 141 and an air outlet end 142, the suction end 141 is connected to the suction port 131 through an air pipe, and the air outlet end 142 is connected to the gas detection assembly 150 through an air pipe, so that the suction pump 140 sucks air from the external environment, and provides power to transmit the air to the gas detection assembly 150, detects the composition of the ambient gas, and feeds back the detection results to the control module 200. In addition, an exhaust port can also be set on the housing 130, and the gas after the gas detection assembly 150 completes the detection is discharged back to the external environment through the exhaust port.

[0065] Preferably, the control module 200 also includes a drone body, which is fixed to the controller 210 and electrically connected to the controller 210. By adopting the drone body, the environmental gas detector can fly in the environment, adapt to different altitudes in mountainous areas or at sea, and the detection environment is more flexible, further solving the technical problem of inconvenient environmental gas detection.

[0066] Among them, see Fig.13 The drone body includes at least four flight brackets 250, and a propeller 251 is provided at the end of each flight bracket 250. The propeller 251 rotates to generate an updraft, thereby enabling the environmental gas detection component 150 to have a flight function.
