[0031] Next, in conjunction with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] In the embodiments of the present application, please refer to Figure 1 , a novel pure steam sampler, which includes a sampling main body 1, which is composed of a housing, two partitions and a plurality of connecting pipes. The two partitions are fixed inside the housing to form a cavity with the housing. The plurality of connecting pipes pass through the two partitions, and a pure steam inlet 11 and an air outlet pipe are respectively connected to both sides. A pressure sensor 7 is provided at the pure steam inlet 11. The end of the air outlet pipe is connected to the inlet end of a two-way three-way valve 8. The two outlet ends of the two-way three-way valve 8 are respectively connected to a sampling bottle connecting pipe and a drain pipe 13. The drain pipe 13 is successively connected to a temperature sensor two 6 and a steam trap 9. The pure steam inlet 11 is connected to the steam pipeline in a conventional manner and is provided with a valve;

[0033] During the use process, first connect the sampling bottle to the sampling bottle connecting pipe in a conventional manner, then steam enters through the pure steam inlet 11, passes through the connecting pipes inside the sampling main body and reaches the two-way three-way valve 8 through the air outlet pipe. Then open the two-way three-way valve 8 to connect the air outlet pipe with the drain pipe 13. At this time, the steam will pass through the temperature sensor two 6 and the steam trap 9 in the drain pipe 13 and then be discharged. The pressure sensor 7 continuously detects the inlet pressure. When the pressure is lower than a certain set value (usually set at 0.15 MPa), an alarm is given to remind to increase or decrease the pure steam flow. When the temperature sensor two 6 detects that the system temperature reaches 121 °C, the system times for 20 minutes to reach the moist heat sterilization condition (according to the steam flow characteristics, from the pure steam inlet 11, the sampler main body 1, the two-way three-way valve 8 to the steam trap 9, the temperature is lower closer to the steam trap 9. When the temperature sensor two 6 detects that the system temperature reaches 121 °C, it can be considered that the previous other positions and the pipelines have reached 121 °C). After the disinfection is completed, control the two-way three-way valve side valve 8 to disconnect the air outlet pipe from the drain pipe 13 and connect the air outlet pipe with the sampling bottle connecting pipe. The steam can then enter the sampling bottle for collection and sampling, and then it ends. During the whole process, all sensors transmit the detection signals to the existing sensor control device, such as the existing PLC or control circuit board, etc. Thus, during the whole sampling process, the inside of the sampler will be disinfected first, thereby ensuring the quality of the sampled pure steam.

[0034] In a further embodiment, a water tank 3 is also included, in which cooling water is filled. The top of the water tank 3 is connected to the top of the cavity through a pipe, and the bottom of the water tank 3 is connected to the bottom of the cavity through another pipe. A circulation pump 4 is arranged in the middle of the pipe, and a cooling device 2 is arranged on the side of the water tank 3. Therefore, during the sampling process (after disinfection), the circulation pump 4 is started to send the water in the water tank 3 into the cavity through the pipe, and then the steam passing through the connecting pipe is cooled to accelerate the condensation of pure steam, thereby increasing the sampling efficiency.

[0035] Furthermore, a cooling water replenishment port 12 is provided at the top of the pipe connected to the top of the water tank 3 to facilitate replenishment of cooling water into the water tank 3 .

[0036] The pipeline equipped with the circulation pump 4 is connected to the drain pipe 13 through a tee pipe, and an electric switch valve 10 is provided between the tee pipe and the drain pipe 13. When the cooling water needs to be replaced, the electric switch valve 10 is opened, and then the circulation pump 4 is started to discharge the cooling water in the water tank 3 through the drain pipe 13 after passing through the electric switch valve 10.

[0037] A temperature sensor 5 is provided on the side of the water tank 3 to monitor the temperature of the cooling water in the water tank 3 in real time.

[0038] In a further embodiment, the cooling device 2 includes a refrigeration box fixed to the side of the water tank 3, an electronic refrigeration sheet 21 is fixed in the refrigeration box and is close to the water tank 3, a heat sink 22 is fixed on the side of the electronic refrigeration sheet 21, an exhaust grille 23 and an air inlet grille 26 are inlaid on the side of the refrigeration box, an exhaust fan 24 is fixed on the side of the exhaust grille 23, and an air guide plate 25 is fixed inside the refrigeration box. The air guide plate 25 is located below the exhaust grille 23 and the exhaust fan 24 and above the air inlet grille 26. The structure of the air guide plate 25 is as follows: Figure 1 As shown, when in use, the air flow normally enters from the air inlet grille 26 and the air guide plate 25, then passes through the heat sink 22 to take away the dissipated heat, and then is discharged through the exhaust grille 23 after being guided by the exhaust fan 24, which can accelerate the discharge of heat and assist the electronic refrigeration sheet 21 to continuously cool the cooling water in the water tank 3.

[0039] The electronic refrigeration chip 21 may be an existing one, and may be connected, controlled and operated in an existing manner.

[0040] A liquid level observation glass plate is inlaid on the side of the water tank 3 to facilitate observation of the situation in the water tank 3.
