In addition, through integrating sampling tube 20, condensation mechanism 30 and clean mechanism 40 in box 10 inside, not only remove very conveniently, need not on-the-spot equipment moreover, let in pure steam in sampling tube 20 alright take a sample pure steam, easy operation, the sample rate is fast.

In another embodiment of the present application, as shown in FIG. 1, the sampling tube 20 is spiral, having a large surface area, which is advantageous for enhancing the condensing effect of the condensing mechanism 30 on the pure steam in the sampling tube 20. Of course, in other embodiments, the coupon 20 may also be rectilinear, spherical, etc.

In another embodiment of the present application, as shown in fig. 1, the sampling tube 20 is vertically arranged, so that after pure steam is converted into condensed water in the sampling tube 20, the condensed water can automatically flow downwards under the action of gravity and be discharged out of the sampling tube 20, which is beneficial to reducing the residual condensed water in the sampling tube 20. Of course, in other embodiments, the coupon 20 may also be disposed horizontally or obliquely.

In another embodiment of the present application, as shown in fig. 1, the sampling tube 20 includes a first tube segment 21 and a second tube segment 22, one end of the first tube segment 21 is communicated with one end of the second tube segment 22, the other end of the first tube segment 21 has an inlet 211, the other end of the second tube segment 22 has a collecting port 221, the first ventilation tube 42 is connected to the communication place between the first tube segment 21 and the second tube segment 22, and both the first tube segment 21 and the second tube segment 22 are communicated with the first ventilation tube 42. The inlet 211 is used for introducing pure steam from outside into the sampling tube 20, and the collection port 221 is used for discharging condensed water in the sampling tube 20. The condensation mechanism 30 may act on the first pipe section 21 alone, may act on the second pipe section 22 alone, or may act on both the first pipe section 21 and the second pipe section 22 together.

When the condensation mechanism 30 acts on the first pipe section 21 alone or acts on the first pipe section 21 and the second pipe section 22 together, there may be residual condensed water in both the first pipe section 21 and the second pipe section 22 after sampling, in which case, when the cleaning mechanism 40 is started, the inlet 211 and the collecting port 221 are both opened, so that a part of the wind blown by the fan 41 enters the first pipe section 21, the condensed water remaining in the first pipe section 21 is discharged from the communicating port, and the other part of the wind enters the second pipe section 22, and the condensed water remaining in the second pipe section 22 is discharged from the collecting port 221. In order to facilitate collection of the condensed water remaining in the sampling tube 20, the condensation mechanism 30 may act on the second tube segment 22 alone, thereby effectively reducing the condensed water formed in the first tube segment 21, and when the cleaning mechanism 40 is started, the inlet 211 is closed, so that the wind energy blown out by the fan 41 can be concentrated into the second tube segment 22, and the condensed water remaining in the second tube segment 22 is concentrated and discharged from the collection port 221.

Further, the second tube section 22 is spiral and vertically arranged.

Further, a flow regulating valve 23 is provided on the first tube section 21 and is positioned close to the access port 211 to better control the amount of pure steam entering the sampling tube 20 per unit time at the source.

In another embodiment of the present application, as shown in fig. 1, the condensing mechanism 30 includes a water tank 31, a water pump 32, a condenser 33, and a heat dissipation fan 34, the second pipe section 22 is disposed in the water tank 31, the inlet 211 and the collecting port 221 are both located outside the water tank 31, the water tank 31 is connected with a water outlet pipe 35 and a return pipe 36, the inlet of the condenser 33 is communicated with the water outlet pipe 35 through the water pump 32, the outlet of the condenser 33 is communicated with the return pipe 36, and the heat dissipation fan 34 is used for dissipating heat from the condenser 33. During operation, water is injected into the water tank 31, so that the second pipe section 22 is fully immersed in the water, and the through inlet 211 and the collecting opening 221 are both positioned outside the water tank 31, thereby ensuring that condensed water in the sampling tube 20 can be discharged outside the water tank 31 through the collecting opening 221 for collection, and avoiding that water in the water tank 31 flows into the sampling tube 20 through the through inlet 211 or the collecting opening 221. During sampling, pure steam introduced into the inlet 211 passes through the first pipe section 21 and then enters the second pipe section 22, and water in the water tank 31 absorbs heat of the pure steam in the second pipe section 22, so that the temperature of the pure steam is reduced, and the pure steam is converted into condensed water, thereby realizing a condensing function. The temperature of the water in the water tank 31 after absorbing the heat of the pure steam will rise, and the condenser 33 and the cooling fan 34 are used for cooling the water in the water tank 31, so as to reduce the temperature of the water in the water tank 31, thereby ensuring that the water in the water tank 31 can continuously convert the pure steam introduced into the second pipe section 22 into condensed water. During operation, the water pump 32 pumps water in the water tank 31 into the condenser 33 from an inlet of the condenser 33 through the water outlet pipe 35, when the water flows through the condenser 33, heat is transferred to the condenser 33, the cooling fan 34 is arranged close to the condenser 33, the heat absorbed by the condenser 33 is diffused into the outside air again, cooled water flows out from an outlet of the condenser 33, and then flows into the water tank 31 again through the return pipe 36 for circulation.

It should be noted that, the end of the second pipe section 22 facing away from the collecting port 221 may extend out of the water tank 31 to be connected to the first pipe section 21, i.e., the first pipe section 21 is located outside the water tank 31, and the condensation mechanism 30 acts on the second pipe section 22 alone. Of course, the end of the second pipe section 22 facing away from the collecting opening 221 may also be located in the water tank 31, and the first pipe section 21 may extend into the water tank 31 to be connected to the second pipe section 22, in which case the condensation mechanism 30 acts together on the first pipe section 21 and the second pipe section 22.

Further, the heat dissipation fans 34 are not limited by adopting an axial flow type, and the number of the heat dissipation fans 34 may be one, two, three or more, specifically four, and are equally arranged on two pairs of two sides of the condenser 33 so as to sufficiently dissipate heat of the condenser 33.

It will be appreciated that the condensation mechanism 30 uses water flowing in the water tank 31 to condense pure steam flowing into the sampling tube 20, and in other embodiments, the condensation mechanism 30 may use air cooling, semiconductor refrigeration, or other refrigeration methods. For example, when the condensing mechanism 30 adopts an air cooling mode, a cooling fan may be disposed in the box 10, and the cooling fan is disposed near the sampling tube 20, and directly uses flowing air blown by the cooling fan to cool pure steam in the sampling tube 20, so as to convert the pure steam into condensed water. For another example, when the condensation mechanism 30 adopts a semiconductor refrigeration mode, a semiconductor refrigeration sheet may be attached to the outer surface of the sampling tube 20, and the refrigeration sheet is used to absorb the heat of the pure steam in the sampling tube 20, so as to reduce the temperature of the pure steam, and thereby convert the pure steam into condensed water.

In another embodiment of the present application, as shown in fig. 1, an injection port 311 is provided on the water tank 31 for injecting water into the water tank 31.

Further, as shown in fig. 1, a cover 39 is provided at the injection port 311 to prevent evaporation of water in the water tank 31.

Further, a temperature measuring member is disposed on the water tank 31, and the temperature measuring member is used for detecting the temperature of water in the water tank 31. When the temperature measuring part detects that the temperature of the water in the water tank 31 is too high, the flow regulating valve 23 on the sampling tube 20 is regulated, the amount of pure steam which is introduced into the sampling tube 20 in unit time is reduced, the burden of the condenser 33 and the cooling fan 34 is lightened, and the influence on the condensation effect due to the too high temperature of the water in the water tank 31 is avoided. The temperature measuring member may specifically be a thermometer.

In another embodiment of the present application, the condenser 33 comprises a finned tube, the inlet of which communicates with the outlet pipe 35 of the water tank 31 through the water pump 32, and the outlet of which communicates with the return pipe 36 of the water tank 31.

After the sampling is finished, the water in the water tank 31 needs to be emptied, firstly, the drain valve 38 is opened, the drain outlet 371 is opened, the water pump 32 continuously works, water flowing out of the outlet of the condenser 33 does not flow into the water tank 31 through the return pipe 36, but enters the drain pipe 37 through the return pipe 36, and finally, most of the water in the water tank 31 is directly discharged to the outside, then, the cleaning mechanism 40 is started, the air blown by the fan 41 enters the water tank 31 through the second ventilation pipe 44, and then, the air sequentially passes through the water pump 32 and the condenser 33, and the outside is discharged from the drain outlet 371 together with the water remained in the water tank 31, the water pump 32 and the condenser 33, so that the water tank 31, the water pump 32 and the condenser 33 are guaranteed to be dried completely, and organic matters such as moss formed in the water tank 31, the water pump 32 and the condenser 33 are effectively avoided, and the condensation effect of the condensation mechanism 30 is effectively guaranteed.

Since the third pipe section 361 is vertically arranged, water flowing out of the outlet of the condenser 33 and flowing into the fourth pipe section 362 in a state where the drain port 371 is opened, while passing through the junction of the fourth pipe section 362 and the third pipe section 361, cannot flow back into the water tank 31 through the third pipe section 361 by the blocking effect of gravity, but is directly discharged to the outside from the drain pipe 37.
