the top end of the exhaust tube is provided with a connector, the top end of the connector is provided with an insertion tube, the connector is clamped with the bottom end of the extension part, and the insertion tube penetrates through the rubber sheet and pushes the plugging plate open;
an air exhaust structure is arranged in the air exhaust pipe.
Furthermore, the top end of the rubber plug is semicircular and the diameter of the rubber plug is larger than that of the bottom end of the rubber plug.
Further, the top end of the storage pipe is provided with an inwards concave connecting part, and the bottom end of the rubber plug is in threaded connection with the connecting part.
Further, the plugging plate is connected with the storage pipe through a spring rotating shaft.
Further, an opening through which the cannula can conveniently penetrate is formed in the center of the rubber sheet.
Further, the connector both sides are equipped with the arc breach, the inside rubber arc piece that is equipped with arc breach cooperation joint of extension.
Further, the air exhaust structure comprises a piston, a piston shaft and a handle, the piston is connected with the piston shaft, the piston shaft is connected with the handle, and the handle is located outside the air exhaust pipe.
Compared with the prior art, the invention has the beneficial effects that:
the form that adopts storage tube and exhaust tube combination utilizes removable formula design, can take off the storage tube alone after having gathered each room sample, changes, makes things convenient for the independent sampling in every room, the accurate formaldehyde content of testing of being convenient for.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Example 1, please refer to fig. 1:
an indoor air sampling device comprises an upper storage tube 2 and a lower exhaust tube 3, wherein a rubber plug 1 is installed at the top end of the storage tube 2 and used for plugging.
As shown in fig. 2-3:
the top end of the rubber plug 1 is semicircular, the diameter of the semicircular shape is larger than that of the bottom end of the rubber plug 1, sealing is better, and the top end of the storage tube 2 is provided with an integrally-formed and inwards-concave connecting part, so that the bottom end of the rubber plug 1 is in threaded connection with the connecting part, and disassembly is convenient;
the plugging plate 6 is arranged in the bottom end of the storage pipe 2 through a spring rotating shaft 7, so that the plugging plate 6 can rotate and is convenient to automatically reset;
set up integrated into one piece's extension in storage tube 2 bottom, set up a sheet rubber 8 in the inside on extension top simultaneously, sheet rubber 8 center department has seted up an opening, shutoff opening after shutoff board 6 rotates, set up integrated into one piece's connector 10 on 3 tops of exhaust tube, connector 10 top sets up integrated into one piece's intubate 9, carry out the gomphosis joint with the arc breach 11 of connector 10 both sides and the inside arc rubber block 12 of extension, make the intubate 9 pass the opening on the sheet rubber 8 simultaneously, 9 backs down shutoff board 6 of intubate this moment, conveniently bleed.
As shown in fig. 4:
the inside structure of bleeding that sets up of exhaust tube 3 for the bleed, wherein the structure of bleeding includes piston 301, piston shaft 302 and handle 303, connects piston 301 with piston shaft 302, connects piston shaft 302 with handle 303, and handle 303 is located the outside of exhaust tube 3 simultaneously.
The use principle is as follows:
during air suction, the rubber plug 1 at the top end of the storage tube 2 is screwed to be detached, the piston 301 is moved by pulling the handle 303, the insertion tube 9 starts air suction, gas enters the storage tube 2, and the rubber plug 1 is installed again after the air suction is finished;
when sampling different rooms, need to change storage tube 2, upwards draw storage tube 2 this moment hard, make inside arc rubber block 12 of extension and the separation of arc breach 11 on the connector 10, will store up storage tube 2 and take off completely, intubate 9 is taken out from storage tube 2 this moment, the external force that plugboard 6 lost intubate 9 and pushed up, because the characteristic of spring spindle 7 is reset and is kick-backed, the opening on the packing rubber sheet 8, avoid the air of sample to expose.
