DETAILED DESCRIPTION

[0023] like Figures 1 to 4 As shown, the utility model provides a gas analyzer sampling device, including a handheld disk 1; a plurality of mounting holes arranged in a circular array are evenly opened on the handheld disk 1; a collecting tube 2 is threadedly connected to each mounting hole; an intermediate tube 4 with a valve 3 is connected to one end of each collecting tube 2; a collecting tube for collecting gas is provided on one side of the handheld disk 1; and the collecting tube can be detachably connected to any intermediate tube 4.

[0024] The principle and beneficial effects of the above technical solution:

[0025] The gas is collected through the collecting tube, and the valve 3 is opened to allow the collected gas to enter the collecting tube 2 through the intermediate tube 4 for storage. When different types of gases need to be collected, the valve 3 is closed, and then the collecting tube is connected to other intermediate tubes 4. Then, the corresponding valve 3 is opened, so that other types of gases can be stored in the corresponding collecting tube 2 through the intermediate tube 4 under the action of the collecting tube. By setting a collecting tube and multiple collecting tubes 2, the collecting tube can be connected to any collecting tube 2, so that different types of gases can be collected and stored, and gas collection and storage can be flexibly performed.

[0026] In this embodiment, Figure 2 As shown, the collecting tube has air inlet holes running through both ends; a plurality of filter slots 5 connected to the air inlet holes are axially opened on the circumferential side of the collecting tube; a fixed column 6 parallel to the collecting tube is connected to the outer wall of the collecting tube through two fixed blocks; a plurality of filter assemblies are arranged on the fixed column 6; each filter assembly can be inserted into the filter slot 5.

[0027] The principle and beneficial effects of the above technical solution:

[0028] The collected gas can be filtered through several filter components after entering the air inlet, so that the filtered gas is stored in the collection tube 2 through the intermediate tube 4. The filter components can effectively remove impurities, particulate matter and pollutants in the gas, thereby improving the purity and quality of the stored gas.

[0029] In this embodiment, Figure 2 , 3 As shown, a plurality of coaxial annular grooves are formed on the fixed column 6; each filter assembly comprises a rotating ring 7 rotatably sleeved in the corresponding annular groove; a plurality of filter rings 8 are evenly arranged on the circumference of each rotating ring 7; each filter ring 8 is connected to the circumference of the rotating ring 7 by a connecting rod; by rotating each rotating ring 7, any filter ring 8 on the circumference of each rotating ring 7 can be inserted into the filter groove 5; an inner ring 9 is connected to the inner thread of each filter ring 8; a filter screen 10 is connected to the inner ring 9; when the filter ring 8 is inserted into the slot, the filter screen 10 is coaxial with the air inlet.

[0030] The principle and beneficial effects of the above technical solution:

[0031] By rotating the rotating ring 7, the filter ring 8 can be driven through the connecting rod to be inserted into the corresponding filter groove 5, so that the filter screen 10 blocks the air inlet, ensuring that the gas flowing into the intermediate tube 4 can be filtered by the filter screen 10, thereby ensuring the filtering effect; when the filtering effect of the filter screen 10 decreases, the filter ring 8 with another filter screen 10 can be replaced and inserted into the filter groove 5 by rotating the rotating ring 7; at the same time, the filter screen 10 can be removed by rotating the inner ring 9, thereby completing the replacement of the filter screen 10; after the inner ring 9 is removed, the filter ring 8 inserted into the filter groove 5 only realizes the function of connection, so that the number of filter screens 10 blocking the air inlet can be adjusted to achieve different degrees of filtering effects.

[0032] In this embodiment, Figure 2 As shown, a radial fixing groove 11 is opened on the circumferential side of each filter ring 8; a plurality of radial fixing holes are opened on the circumferential side of the collection tube; each fixing hole is connected to the corresponding filter tank 5; when the filter ring 8 is inserted into the filter tank 5, the fixing groove 11 is coaxial with the fixing hole, and a screw 12 that can be inserted into the fixing groove 11 is threadedly connected to each fixing hole.

[0033] The principle and beneficial effects of the above technical solution:

[0034] When the filter ring 8 is inserted into the filter tank 5, the fixing groove 11 is coaxial with the fixing hole, and then the screw 12 is rotated to allow the screw 12 to be inserted into the fixing groove 11 to limit the filter ring 8 and prevent the filter ring 8 from accidentally leaving the filter tank 5 during gas collection.

[0035] In this embodiment, Figure 1 As shown, a plurality of positioning components are provided on one side of the handheld disk 1 close to the collecting tube; each positioning component includes two positioning blocks 13 connected to the handheld disk 1, and the two positioning blocks 13 are located on both sides of the corresponding mounting hole; each positioning block 13 is connected to a positioning rod 14 parallel to the collecting tube 2, and a positioning ring 15 is connected to one end of the collecting tube close to the handheld disk 1; the positioning ring 15 is slidably mounted on the positioning rod 14 through the opened positioning hole; each positioning rod 14 is threadedly connected to a nut 16 for pressing the positioning ring 15 onto the positioning block 13.

[0036] The principle and beneficial effects of the above technical solution:

[0037] Sleeve the positioning ring 15 on the positioning ring 15, then rotate the nut 16, and use the nut 16 to press the positioning ring 15 onto the positioning block 13. At this time, the intermediate tube 4 is connected to the collection tube, and then open the valve 3 so that the gas can be stored in the collection tube 2 through the intermediate tube 4.

[0038] In this embodiment, Figure 1 , 4 As shown, an end of the collection tube close to the handheld disk 1 is connected to an air intake pipe 17; an end of the air intake pipe 17 away from the collection tube can be sleeved with the intermediate tube 4; a positioning ring 15 is fixedly sleeved on the outside of the air intake pipe 17; a frame is provided inside the air intake pipe 17; and an air intake fan 18 is installed on the frame.

[0039] The principle and beneficial effects of the above technical solution:

[0040] The suction fan 18 is controlled to rotate, thereby generating suction, so that the gas can enter from the collection tube away from one end of the handheld tray 1, and enter the intermediate tube 4 through the suction pipe 17, and then be stored in the collection tube 2.

[0041] In this embodiment, Figure 1 As shown, a hand-held rod 19 is coaxially connected to the side of the hand-held disk 1 facing away from the collection component.

[0042] The principle and beneficial effects of the above technical solution:

[0043] The device can be carried by means of a handle 19 .

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
