The equipment may be designed as a closed system to prevent airborne contaminants from entering the sample, especially in laboratory environments with high water quality requirements.
[0003] In specific purified water sampling, the testing capacity of purified water is usually specified. However, when using vacuum vessels to fill purified water, it is impossible to achieve accurate filling, which affects the test results of purified water. Furthermore, it is not possible to make the purified water into a vacuum state during sampling, which is inconvenient for the operator.
[0004] Therefore, it is particularly important to improve existing purified water sampling equipment and design a new type of purified water sampling equipment to solve the above-mentioned technical defects and improve the overall practicality of purified water sampling equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example:
[0026] Please see Figures 1-6 This utility model provides a technical solution:
[0027] A purified water sampling device includes a sampling tube 1, with support plates 2 symmetrically fixedly connected to the top and bottom of the sampling tube 1. An auxiliary rod 3 is fixedly connected between the two sets of support plates 2. An extension cylinder 4 is fixedly connected to the top of the sampling tube 1, and a motor 5 is fixedly connected to the top of the extension cylinder 4. A scale 6 is provided on the outside of the sampling tube 1. A sleeve 7 is fixedly connected to the bottom of the sampling tube 1, and a contact plate 8 is fixedly connected to the bottom of the sleeve 7. A lead screw 9 is rotatably connected inside the extension cylinder 4, and a limiting plate 10 is sleeved on the outside of the lead screw 9. An extension rod 11 is fixedly connected to the bottom of the limiting plate 10, and a sealing device is fixedly connected to the bottom of the extension rod 11. The sampling tube 1 is held vertically in the hand, and the contact plate 8 is brought into contact with the water to be tested. The auxiliary rod 3 is designed to protect the sampling tube 1, extend its service life, and provide a grip for easy handling. Then, the motor 5 is driven, and the output of the motor 5 drives the limiting plate 10 to rotate spirally. Then, under the action of the inner wall of the sampling tube 1, the tube is lifted and lowered. Subsequently, the extension rod 11 and the sealing plate 12 move, creating a negative pressure inside the sampling tube 1, and the water to be sampled is drawn into the sampling tube 1 from the contact plate 8.
[0028] Furthermore, in this embodiment, an auxiliary tube 13 is symmetrically fixedly connected to the outside of the sampling tube 1. The auxiliary tube 13 is interconnected with the inside of the sampling tube 1. A fixed cylinder 14 is fixedly connected to the top of the auxiliary tube 13. An exhaust pipe 15 is fixedly connected to the top of the fixed cylinder 14. When the sampled water enters the inside of the sampling tube 1, the water flow is synchronously introduced into the inside of the auxiliary tube 13 because the auxiliary tube 13 is interconnected with the inside of the sampling tube 1.
[0029] Furthermore, in this embodiment, one end of the exhaust pipe 15 is rotatably connected to the connecting pipe 16, and the end of the connecting pipe 16 away from the exhaust pipe 15 is fixedly connected to the linkage pipe 17. A first spring 18 is sleeved between the exhaust pipe 15 and the connecting pipe 16. When it is necessary to discharge the air inside the sampling tube 1 and simultaneously achieve precise filling of purified water, the linkage pipe 17 is squeezed, which in turn causes the connecting pipe 16 to shift and stretches the first spring 18. The gas will directly enter from the gap between the connecting pipe 16 and the exhaust pipe 15, and then be discharged from the inside of the exhaust pipe 15 to the outside. After the gas is discharged, the water level inside the sampling tube 1 drops and does not reach the predetermined value. Then, the water inside the auxiliary pipe 13 will flow into the sampling tube 1. When the predetermined value is reached, the first spring 18 will be reset by releasing the insertion rod 20, aligning the connecting pipe 16 and the exhaust pipe 15.
[0030] Furthermore, in this embodiment, a collar is fixedly connected to the outside of the linkage pipe 17, and a floating block 19 is fixedly connected to the bottom of the collar. The external structural size of the floating block 19 is the same as the structural size of the fixed cylinder 14. An insert rod 20 is fixedly connected to the top of the collar, and the insert rod 20 extends to the outside of the fixed cylinder 14. By squeezing the insert rod 20, the collar is subjected to pressure, which causes the connecting pipe 16 and the exhaust pipe 15 to tilt, expelling air. Finally, the reset action of the first spring 18 will align the connecting pipe 16 and the exhaust pipe 15, thereby raising the floating block 19.
[0031] Furthermore, in this embodiment, a wheel 21 is rotatably connected to the outside of the sleeve 7, and an insert shaft is fixedly connected inside the wheel 21. The insert shaft extends into the inside of the sleeve 7, and a sealing plate 22 is fixedly connected to the outside of the insert shaft. By rotating the wheel 21, the insert shaft rotates accordingly, and the sealing plate 22 is then in a vertical state inside the sleeve 7, thus achieving communication between the sleeve 7 and the sampling tube 1, which facilitates water extraction.
[0032] Furthermore, in this embodiment, a filter screen 23 is slidably connected inside the contact plate 8, and a first sleeve 24 is fixedly connected to the outside of the contact plate 8. An extension shaft 25 is slidably connected inside the first sleeve 24. A second spring 26 is sleeved inside the first sleeve 24 and outside the extension shaft 25. A second sleeve 27 is fixedly connected to the outside of the extension shaft 25. Both the first sleeve 24 and the second sleeve 27 have beveled edges on their sides. An auxiliary handle is fixedly connected to the end of the second sleeve 27 away from the first sleeve 24. After water is drawn in, particles and impurities in the water are filtered out by the filter screen 23. The filter is used to prevent impurities from entering the sampling tube 1. When the filter screen 23 is used for filtering for a long time, impurities will block the surface of the filter screen 23. By pulling the auxiliary handle outward, the extension shaft 25 will be pulled out from the inside of the filter screen 23, and the connection between it and the filter screen 23 will be released. Then, the extension shaft 25 is rotated so that the inclined surfaces between the first sleeve 24 and the second sleeve 27 are pressed against each other, fixing the position of the extension shaft 25. After the cleaned filter screen 23 is placed inside the contact plate 8, the extension shaft 25 is inserted into the inside of the filter screen 23 by the second spring 26.
[0033] In this embodiment, the specific implementation scenario is as follows: The sampling tube 1 is held vertically in the hand, and the contact plate 8 is brought into contact with the water to be tested. The wheel 21 is rotated, and the insertion shaft follows suit. The sealing plate 22 is then in a vertical position inside the sleeve 7, establishing communication between the sleeve 7 and the sampling tube 1. The filter screen 23 filters particulate impurities in the water, preventing them from entering the sampling tube 1. The auxiliary rod 3 protects the sampling tube 1, extending its lifespan, and provides grip for easy handling. The motor 5 is then driven, and its output drives the limiting plate 10 to rotate spirally. Under the action of the inner wall of the sampling tube 1, it achieves lifting and lowering motion. The extension rod 11 and the sealing plate 12 then move, creating a negative pressure inside the sampling tube 1. The water to be sampled is drawn into the sampling tube 1 from the contact plate 8. Since the auxiliary tube 13 is interconnected with the sampling tube 1, water flows synchronously into the auxiliary tube 13. The insertion rod 20 is then... The compression causes the collar to tilt, resulting in the connection between the connector 16 and the exhaust pipe 15. Gas enters directly from the gap between the connector 16 and the exhaust pipe 15 and then exits from the inside of the exhaust pipe 15 to the outside. After the gas is discharged, the water level inside the sampling tube 1 drops. If the predetermined value is not reached, water from the auxiliary tube 13 will flow into the sampling tube 1. When the predetermined value is reached, the first spring 18 will align the connector 16 and the exhaust pipe 15 by releasing the insertion rod 20, thus aligning the floating block 19. As the filter screen 23 rises, impurities will clog its surface during prolonged filtration. By pulling the auxiliary handle outward, the extension shaft 25 will be pulled out from inside the filter screen 23, detaching it from the filter screen 23. Then, the extension shaft 25 is rotated, causing the inclined surfaces of the first sleeve 24 and the second sleeve 27 to press against each other, fixing the position of the extension shaft 25. After the cleaned filter screen 23 is placed inside the contact plate 8, the extension shaft 25 is inserted into the filter screen 23 by the second spring 26.
