DETAILED DESCRIPTION

[0024] The utility model will be further described below in combination with the drawings and embodiments.

[0025] As Figures 1 to 4As shown, an ambient air sampling temperature control device includes a housing 1, which comprises a placement chamber 4, a circulating water extraction chamber 5, and a heating chamber 6. The placement chamber 4 and the heating chamber 6 are in cyclic communication. The housing 1 is provided with an openable or closable cover. The placement chamber 4 is provided with a bladder 7 that divides the placement chamber 4 into two parts. The lower half of the bladder 7 is provided with circulating water that is in cyclic communication with the heating chamber 6. The bladder 7 is provided with a plurality of sampling tube receiving bags 71 for placing gas sampling tubes. The cover is provided with a sampling structure that corresponds to the gas sampling tubes for sampling. The cover is also provided with a heating device for facilitating the heating of the circulating water in the heating chamber 6. The circulating water extraction chamber 5 is provided with an extraction device for transporting the circulating water in the placement chamber 4 to the heating chamber 6.

[0026] In this embodiment, the box 1 is a cuboid structure. When the bladder 7 is fixedly installed in the placement chamber 4, a sealed structure is formed below the bladder 7 to store circulating water. Since the bladder 7 is a flexible structure, when the circulating water circulates, the bladder 7 can effectively withstand the fluctuations of the water flow, ensuring that the gas sampling tube is effectively placed in the sampling tube receiving bag 71.

[0027] like Figure 3 As shown, the sampling structure includes an inlet pipe 8 and an outlet pipe 9 fixedly mounted on the cover plate, corresponding one-to-one with the gas sampling tube inlet 13 and outlet 12. Each inlet pipe 8 is connected to the main inlet pipe 10, and each outlet pipe 9 is connected to the main outlet pipe 11. Each inlet pipe 8 and outlet pipe 9 is equipped with a valve 16 for easy switching. Since each gas sampling tube has an inlet 13 and an outlet 12, the corresponding inlet pipe 8 and outlet pipe 9 ensure effective gas intake and exhaust within the gas sampling tube. Furthermore, the intake manifold 8 and the exhaust manifold 9 are combined into the intake manifold 10 and the exhaust manifold 11, which facilitates air extraction and exhaust. When a gas sampling tube needs to be sampled, the valve 16 of the corresponding gas sampling tube is opened, and the sampled gas will enter the corresponding gas sampling tube. When the valve 16 is closed, another valve 16 is opened, and the sampled gas will enter the other gas sampling tube, which effectively improves the sampling efficiency. When the sampled gas is discharged, it is only necessary to open the valve 16 on the corresponding exhaust manifold 9, and the sampled gas will enter the exhaust manifold 11 for discharge.

[0028] In the embodiment, the pumping device comprises a water pumping pump 14 fixedly installed in the circulating pumping chamber 5, the water pumping pump 14 is provided with a water pumping pipe 141, the placing chamber 4 is communicated with the heating chamber 6 through the water pumping pipe 141, and a water outlet hole 15 is further arranged between the placing chamber 4 and the heating chamber 6. The circulating pumping chamber 5 is adjacently installed with the heating chamber 6 and the placing chamber 4, and the circulating pumping chamber 5 is free of circulating water. Therefore, the placing chamber, the water pumping pump 14 and the heating chamber 6 are sequentially communicated through the water pumping pipe 141, so that the water pumping of the placing chamber can be completed, and the circulating water in the heating chamber 6 flows out from the water outlet hole 15 due to the pumping of the circulating water in the placing chamber 4, so as to keep the pressure balance between the heating chamber 6 and the placing chamber 4, and the circulating water flow can make the temperature more uniform, thereby ensuring the constant temperature effect. Since the water pumping pump 14 is a commercially available structure, it is not described in detail herein.

[0029] As shown in Figure 1 and Figure 4 , the heating device comprises a heating pipe 17, the cover plate is provided with a heating gap 18 for facilitating the deepening of the heating pipe 17, and the heating pipe 17 is provided with a placing plate 171 at the top, and the placing plate 171 is larger than the heating gap 18. In the embodiment, the heating pipe 17 is a U-shaped tubular structure, and the heating pipe 17 can heat the circulating water after being connected with a power supply. Moreover, the placing plate 171 is larger than the heating gap 18, so that the placing plate 171 can cover the cover plate, and the heating pipe 17 is suspended in the heating chamber 6, thereby further improving the heating effect of the circulating water. The heating pipe 17 is a commercially available structure.

[0030] Further, the cover plate comprises a first cover plate 2 and a second cover plate 3, the first cover plate 2 corresponds to the circulating pumping chamber 5 and the heating chamber 6, the heating gap 18 is arranged on the first cover plate 2, the second cover plate 3 corresponds to the placing chamber 4, the air inlet branch pipe 8 and the air outlet branch pipe 9 are fixedly installed on the second cover plate 3, and the first cover plate 2 and the second cover plate 3 are hingedly installed on the box body 1, so that they can be separately controlled. Since the gas sampling pipe in the placing chamber 4 needs to be replaced, the second cover plate 3 can be flipped to facilitate the placement of the gas sampling pipe, and can effectively prevent external impurities from entering the placing chamber 4 and affecting sampling. The first cover plate 2 can also effectively prevent external impurities from entering the heating chamber 6 and the circulating pumping chamber 5.

[0031] In the embodiment, the air inlet branch pipe 8 and the air outlet branch pipe 9 are both PU hoses, so that when connected, the air inlet branch pipe 8 and the air outlet branch pipe 9 can be simply sleeved on the air inlet 13 and the air outlet 12 of the gas sampling pipe, thereby achieving connection, which is convenient and fast.

[0032] Further, the sampling tube containing bag 71 is made of flexible material, and the sampling tube containing bag 71 is identical in shape with the gas sampling tube; thus, after the gas sampling tube is placed in the sampling tube containing bag 71, the circulating water extruding the sampling tube containing bag 71 can make the sampling tube containing bag 71 closely adhere to the gas sampling tube, so that the sampling tube containing bag 71 can be well heat-conducted.

[0033] The working principle of the embodiment is as follows: first, open the valves 16 on the gas inlet branch pipe 8 and the gas outlet branch pipe 9 corresponding to the first gas sampling tube, and then sample gas enters the gas inlet main pipe 10, and then enters the gas inlet branch pipe 8 corresponding to the gas sampling tube, and finally enters the gas sampling tube, and then close the valves 16 on the gas inlet branch pipe 8 and the gas outlet branch pipe 9 corresponding to the gas sampling tube; when the next sampling is waited, open the valves 16 on the gas inlet branch pipe 8 and the gas outlet branch pipe 9 of another gas sampling tube, complete the sampling of another gas sampling tube, repeat the above operation until the required sampling is completed, and at the same time of sampling, the heating pipe 17 works to heat, and the water pump 14 also starts to work, and the circulating water in the placing chamber 4 is transported to the heating chamber 6 through the water suction pipe 141, the circulating water in the heating chamber 6 flows into the placing chamber 4 from the water outlet, and when the circulating water reaches the specified temperature, the heating rod stops heating, and when the circulating water is lower than the specified temperature, the heating rod starts to heat.

[0034] The above-described embodiment is only a description of the preferred embodiment of the present application, and is not intended to limit the scope of the present application, and various modifications and improvements of the technical solutions of the present application made without departing from the design spirit of the present application shall fall within the protection scope of the present application determined by the claims.
