[0022] After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of this application.
[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.
[0025] The embodiments of the utility model are further described in detail below in conjunction with the accompanying drawings.
[0026] The utility model provides a harmful volatile matter detection device, such as Figure 1 As shown, the device includes an air inlet pipe 1, a first sliding box 2, a water absorption assembly 3, a slide rail 4, a second sliding box 5 and an air outlet pipe 6;
[0027] The air inlet pipe 1 is arranged on the top of the first sliding box 2, the water absorption component 3 is arranged inside the first sliding box 2, the first sliding box 2 is slidably arranged on the slide rail 4, the slide rail 4 is vertically arranged on the second sliding box 5, and the second sliding box 5 is fixedly connected to the air outlet pipe 6.
[0028] Specifically, when the harmful volatiles are detected, the harmful volatiles enter the first sliding box 2 from the air inlet pipe 1 , pass through the first sliding box 2 into the second sliding box 5 , and are discharged from the air outlet pipe 6 .
[0029] Furthermore, if Figure 2 As shown, it is a schematic diagram of the structure of a water absorption assembly of the utility model, the water absorption assembly 3 includes a frame 31, a fixing frame 32 arranged on the side of the frame 31, and a water absorption bag 33. The frame 31 is suspended on the top of the first sliding box 2, and the fixing frame 32 is arranged horizontally on the side of the frame 31. The water absorption bag 33 is placed in the hollow space formed by the fixing frame 32. The number of water absorption assemblies 3 can be set according to actual needs.
[0030] Specifically, the frame 31 can be fixed and suspended on the top of the first sliding box 2 by screws, and a fixing frame 32 is horizontally arranged on each of the four sides of the frame 31. The four fixing frames 32 and the frame 31 form a hollow space, and the water absorbent bag 33 is placed in the hollow space; it can be understood that the height of the water absorbent bag 33 is higher than the height of the fixing frame 32 from the bottom of the frame 31, which can prevent the water absorbent bag 33 from slipping out of the hollow space during use and facilitate the replacement of the water absorbent bag 33.
[0031] It can be understood that when harmful volatiles enter the first sliding box 2, the water absorption component 3 located in the first sliding box 2 can quickly absorb the moisture in the harmful volatiles to effectively reduce the influence of moisture on the accuracy of the test results; however, the water absorption capacity of the water absorption bag 33 is limited and therefore needs to be replaced regularly. When replacing, the second sliding box 5 can be slid downward, and the second sliding box 5 slides along the slide rail 4 to achieve separation from the first sliding box 2. When the second sliding box 5 slides to the bottom of the slide rail 4, the gap between the first sliding box 2 and the second sliding box 5 can achieve the replacement of the water absorption bag 33.
[0032] The beneficial effect of the utility model is that the first shell 21 and the second shell 51 can be freely separated by connecting through the slide rail 4. When the first shell 21 and the second shell 51 are separated, the water-absorbing material can be replaced without disassembling the shells, thereby effectively improving the efficiency of replacing the water-absorbing bag 33.
[0033] Furthermore, in the utility model, the first sliding box 2 includes a first shell 21, a detection component 22 and an air guide component 23 arranged in the first shell 21, the water absorption component 3 is located above the detection component 22, the detection component 22 is located above the air guide component 23, and the air guide component 23 passes through the bottom of the first shell 21 and the top of the second sliding box 5 in sequence.
[0034] Specifically, Figure 3As shown, it is a schematic diagram of the structure of a first sliding box of the utility model. When harmful volatiles enter the first shell 21, the water absorption component 3 first absorbs the moisture in the harmful volatiles. After a preset period of time, the detection component 22 detects the concentration of the harmful volatiles. At the same time, the harmful volatiles continue to flow and enter the second sliding box 5 through the air guide component 23 located at the bottom of the first shell 21.
[0035] Furthermore, in the utility model, the air guide assembly 23 includes a retractable closing device 231 and an air guide tube 232. The retractable closing device 231 is located at the bottom of the inner side of the first shell 21. The retractable closing device 231 is hinged at the top of the air guide tube 232. The air guide tube 232 passes through the bottom of the first shell 21 and the top of the second sliding box 5.
[0036] Among them, the contraction and closing device 231 includes a main contraction and closing blade 2311 and a sub-contraction and closing blade 2312, and the main contraction and closing blade 2311 intersects vertically with the sub-contraction and closing blade 2312; the main contraction and closing blade 2311 is hinged on the airway 232 through a connecting shaft.
[0037] like Figure 4 The figure is a schematic diagram of the structure of the retractable closing device 231 of the utility model. It can be understood that when the second sliding box 5 slides downward, the air guide tube 232 in the air guide assembly 23 moves downward simultaneously with the second sliding box 5, and the main retractable closing blade 2311 in the retractable closing device 231 hinged with the air guide tube 232 gradually rotates upward under the push of the first shell 21. When the second sliding box 5 slides to the bottom of the slide rail 4, the main retractable closing blade 2311 rotates 90°, and the four sub-retractable closing blades 2312 are closed; in the embodiment of the present application, the air guide tube 232 is a rectangular parallelepiped; when the second sliding box 5 slides to the bottom, the sub-retractable closing blade 2312 can play a blocking role to prevent the air guide tube 232 from sliding out of the first shell 21. In the embodiment of the present application, the sub-contracting and closing blade 2312 is in the shape of a right triangle, and the length of the hypotenuse of the sub-contracting and closing blade 2312 is the same as the width of the main contracting and closing blade 2311. Therefore, when the vertices corresponding to the four sub-contracting and closing blades 2312 intersect at one point, the four sub-contracting and closing blades 2312 form a square to block the air duct 232. The contraction and closing device 231 is hinged to the air duct 232 through the connecting shaft to realize the free rotation of the blades. When the second shell 51 drives the air duct 232 to move, the closing of the contraction and closing device 231 can avoid the pollution of the air duct 232 by the outside air during replacement. It can be understood that the slide rail 4 itself has a damping effect and will not slide freely due to gravity.
[0038] Furthermore, in the present invention, the second sliding box 5 includes a second shell 51 and a purification membrane 52 disposed inside the second shell 51 .
[0039] Specifically, when harmful volatiles enter the second shell 51 , they will pass through the purification membrane 52 , and the purification membrane 52 can purify the harmful volatiles. The purified harmful volatiles are discharged through the outlet pipe 6 to effectively reduce pollution to the environment.
[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
