[0026] As Figures 1 to 4As shown, the embodiment of the present application provides a fluid sampling mechanism for sampling the water quality inside the refrigerator, which comprises a buffer barrel 10 and a mixing barrel 20. The buffer barrel 10 and the mixing barrel 20 are both arranged at the top end of the refrigerator. The mixing barrel 20 is arranged at one side of the buffer barrel 10. The buffer barrel 10 is connected to the pipe body inside the refrigerator and can extract the water inside the refrigerator. The mixing barrel 20 is in communication with the buffer barrel 10. In this way, when it is necessary to detect the water sample inside the refrigerator, the buffer barrel 10 extracts the water sample inside the refrigerator and buffers the water sample in the buffer barrel 10. At the same time, the water sample buffered in the buffer barrel 10 can be sent to the mixing barrel 20 for mixing. The mixed water sample can make the detection data more accurate.
[0027] The mixing barrel 20 is provided with a driving member 30 and a stirring paddle 40. The driving member 30 is arranged on the mixing barrel 20, and the stirring paddle 40 is arranged in the mixing barrel 20. The driving member 30 is in communication with the stirring paddle 40. The mixing barrel 20 can be filled with clean water or the water sample to be detected. When it is necessary to mix the water sample in the mixing barrel 20, the driving member 30 drives the stirring paddle 40 to rotate, and the stirring paddle 40 stirs the water sample in the mixing barrel 20. When clean water is filled in the mixing barrel 20, the rotation of the stirring paddle 40 can bring the impurities attached to the barrel wall of the mixing barrel 20 into the clean water, so as to clean the mixing barrel 20. Specifically, the driving member 30 is an electric motor. Of course, the driving member 30 can also be a motor, which can drive the stirring paddle 40 to rotate.
[0028] In order to facilitate the water sample in the buffer barrel 10 to flow into the mixing barrel 20, a support 50 is arranged at the top of the refrigerator. The buffer barrel 10 is arranged on the support 50. The support 50 is used to lift the position of the buffer barrel 10. Therefore, the height of the buffer barrel 10 is greater than the height of the mixing barrel 20. In this way, it is convenient for the water sample in the buffer barrel 10 to enter the mixing barrel 20. Overflow ports are arranged on the buffer barrel 10 and the mixing barrel 20. The two overflow ports are connected by a pipeline. It should be understood that when the buffer barrel 10 is installed on the support 50, the overflow port of the buffer barrel 10 is higher than the upper surface of the mixing barrel 20. In this way, the water sample in the buffer barrel 10 can quickly flow into the mixing barrel 20 by the gravity of water. Of course, a switch valve can be arranged between the buffer barrel 10 and the mixing barrel 20 to control the opening and closing of the water flow. When it is necessary to flow the water sample in the buffer barrel 10 into the mixing barrel 20, the switch valve can be opened. When the water sample in the mixing barrel 20 reaches a set amount, the switch valve is closed, and the water sample in the buffer barrel 10 cannot flow into the mixing barrel 20.
[0029] In an embodiment, the mixing barrel 20 and the buffer barrel 10 are provided with a cleaning mechanism 60, which can clean the inside of the mixing barrel 20 and the buffer barrel 10. The cleaning mechanism 60 can access external clean water, and the external clean water enters the inside of the mixing barrel 20 and the buffer barrel 10 through the cleaning mechanism 60 to clean the inside of the mixing barrel 20 and the buffer barrel 10.
[0030] Specifically, the cleaning mechanism 60 includes a turbine nozzle 61 and a water inlet pipe 62. The turbine nozzle 61 is arranged on the mixing barrel 20 or the buffer barrel 10, and the water inlet pipe 62 is connected to the turbine nozzle 61. The water inlet pipe 62 accesses external clean water, and the clean water flows from the water inlet pipe 62 to the turbine nozzle 61. The turbine nozzle 61 can provide water with pressure, i.e., can spray water to the inner wall of the mixing barrel 20 or the buffer barrel 10. The water with pressure can clean the impurities on the inner wall. In this way, the impurities inside the mixing barrel 20 and the buffer barrel 10 can be cleaned, and when the water sample to be detected is introduced into the inside of the buffer barrel 10 and the mixing barrel 20, the pollution of the impurities can be avoided, and the accuracy of the detection can be ensured. When installed, the driving member 30 and the stirring paddle 40 on the mixing barrel 20 are arranged at the middle position of the mixing barrel 20, and the turbine nozzle 61 on the mixing barrel 20 is arranged on both sides of the driving member 30. In this way, the inside of the mixing barrel 20 can be cleaned during cleaning.
[0031] In an embodiment, the buffer barrel 10 is provided with a water pump 70 on one side. The water pump 70 is connected to the water inlet pipe 62. A first valve body 80 is arranged below the water pump 70. The first valve body 80 is connected to a first pipe body 90 and a second pipe body 100. The first pipe body 90 is connected to the water inlet pipe 62, i.e., the water from the water inlet pipe 62 into the buffer barrel 10 passes through the first pipe body 90 and then enters the water inlet pipe 62, and finally enters the buffer barrel 10. A second valve body 110 is arranged between the first pipe body 90 and the water inlet pipe 62. The second valve body 110 is used to control the opening and closing of the first pipe body 90 and the water inlet pipe 62. The second pipe body 100 is configured as an emergency pipe body and is connected to a pipe body inside the refrigerator. In this way, in special cases, when the water sample inside the refrigerator needs to be directly detected, the water sample can be directly sampled and detected without passing through the buffer barrel 10 and the mixing barrel 20.
[0032] Specifically, the water inlet pipe 62 includes a third pipe body 621 and a fourth pipe body 622. One end of the third pipe body 621 is connected to the turbine nozzle 61, and the other end of the third pipe body 621 is connected to the second valve body 110. The fourth pipe body 622 is connected to the second valve body 110, and the other end of the fourth pipe body 622 is a water inlet end.
[0033] It should be understood that in this application, the mixing barrel 20 and the buffer barrel 10 have the same structure. That is, the structure of the mixing barrel 20 is the same as that of the buffer barrel 10. The difference is that the driving member 30 and the stirring paddle 40 are installed in the middle of the mixing barrel 20.
[0034] It should be finally pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
