DETAILED DESCRIPTION

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present utility model provides a multifunctional collection device for environmental monitoring, such as Figure 1-4 As shown, it comprises: an air collector 1, four fixing sleeves 2 are evenly fixedly connected to the top of the air collector 1, a collecting tube 3 is arranged inside the fixing sleeve 2, and a sealing cover 4 is threadedly connected to the top of the collecting tube 3; a piston 5 is arranged inside the collecting tube 3, and a fixing block 6 is fixedly connected at the center of the collecting tube 3 and the sealing cover 4, a one-way air hole 7 is opened inside the fixing block 6, a sealing bead 8 is arranged inside the one-way air hole 7, and a conical spring 9 is arranged at the bottom of the sealing bead 8, and the conical spring 9 is respectively arranged inside the one-way air hole 7; an elastic mechanism 10 for quickly disassembling and assembling the collecting tube 3 is arranged inside the fixing sleeve 2.

[0021] It should be noted that the air collector 1 extracts the air inside the collection tube 3 from the bottom of the collection tube 3, so that negative pressure is generated inside the collection tube 3, thereby causing the piston 5 to slide slowly downward, and at the same time causing negative pressure to be generated on the top of the piston 5. The outside air pushes the sealing bead 8 through the one-way air hole 7, and then enters the inside of the collection tube 3 from the gap between the sealing bead 8 and the one-way air hole 7. When the air pressure inside the collection tube 3 is consistent with that of the outside, the conical spring 9 pushes the sealing bead 8 and the one-way air hole 7 to seal, thereby achieving the goal of discharging the original air inside the collection tube 3 while collecting the outside air, thereby avoiding the mixing of the collected air with the original air inside the collection tube 3, and solving the problem that the current collection device can collect air, but does not discharge the original air in the tube while collecting, resulting in the mixing of the collected air with the original air in the tube, resulting in large errors in the data results of air detection.

[0022] In a further preferred embodiment of the present invention, Figure 1 , 3 As shown, the elastic mechanism 10 includes: six limiting holes 11 are opened inside the fixing sleeve 2, steel balls 12 are arranged inside the limiting holes 11, springs 13 are arranged on the side of the steel balls 12 away from the collection tube 3, and the springs 13 are arranged inside the limiting holes 11; the outer surface of the collection tube 3 near the steel balls 12 is opened with a card slot 14, and the card slot 14 is adapted to the steel balls 12.

[0023] In this embodiment, the user can insert the collection tube 3 into the interior of the fixing sleeve 2 and apply downward pressure. The collection tube 3 pushes the steel ball 12 while entering, so that the steel ball 12 enters the interior of the limiting hole 11. When the collection tube 3 completely enters the interior of the fixing sleeve 2, the spring 13 pushes the steel ball 12 so that a small part of the steel ball 12 moves to the card groove on the surface of the collection tube 3, thereby fixing the collection tube 3 and facilitating the user to install or take the collection tube 3.

[0024] In a further preferred embodiment of the present invention, Figure 1 As shown, the collecting tube 3 comprises a tube body 15 and a detachable arc-shaped base 16 , and the bottom of the tube body 15 is threadedly connected with the arc-shaped base 16 .

[0025] In this embodiment, the user can open the sealing cover 4 and the arc-shaped base 16, take out the piston 5 inside the collection tube 3 and then insert it from the top of the collection tube 3, so that the collection tube 3 can be recycled for multiple times, saving the use cost.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, a sealing gasket 17 is fixedly connected to the outer surface of the piston 5 , and the piston 5 is matched with the fixing block 6 .

[0027] In this embodiment, the sealing performance at the contact point between the piston 5 and the collection tube 3 is improved to prevent air leakage.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, a sealing block 18 is fixedly connected to the bottom of the fixed sleeve 2 , and the sealing block 18 is adapted to the collection tube 3 .

[0029] In this embodiment, the sealing performance of the connection between the collection tube 3 and the fixing sleeve 2 is improved to prevent air leakage.

[0031] In this embodiment, the air collector 1 can simultaneously extract the air inside the collection tube 3 through the suction hole 19, thereby achieving the purpose of collecting multiple portions of air at the same time, thereby improving work efficiency.
