Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water quality control device. Background Technology

[0002] Hospital endoscopy centers require large quantities of sterile, purified water for endoscope cleaning and disinfection, especially for the final rinse water, where the total bacterial count must be less than 10 CFU / ml. However, current technologies typically employ conventional membrane purification techniques (such as reverse osmosis (RO) membranes) for water circulation and purification, but this technology has limitations. For example, it suffers from insufficient purification capacity. While conventional purification technologies can remove most impurities and some bacteria, the bacterial count accumulates during repeated cycles, leading to water quality deterioration. This not only affects the cleaning effectiveness of the endoscopes but may also increase the risk of patient infection. Furthermore, existing systems are inadequate in water quality monitoring and real-time control, making it difficult to ensure that the total bacterial count in the final rinse water remains below 10 CFU / ml.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 This utility model discloses a water quality control device, comprising a raw water tank 1, a pure water tank 2, and a water purification system 3 disposed between the raw water tank 1 and the pure water tank 2. The raw water tank 1 stores untreated natural water. The water in the raw water tank 1 is treated by the water purification system 3 before entering the pure water tank 2. The pure water tank 2 is connected to a water inlet 4 for leading water out to clean an endoscope. A circulation system 5 is provided between the pure water tank 2 and the water inlet 4 to circulate the water in the pure water tank 2 between the pure water tank 2 and the water inlet 4.

[0026] The water purification system 3 includes a mechanical filter 31, an activated carbon filter 32, a softening filter 33, a precision filter 34, and a reverse osmosis device 35. The raw water tank 1, the mechanical filter 31, the activated carbon filter 32, the softening filter 33, the precision filter 34, and the reverse osmosis device 35 are connected sequentially. That is, after the water in the raw water tank 1 flows out of the raw water tank 1, it passes through the mechanical filter 31, the activated carbon filter 32, the softening filter 33, the precision filter 34, and the reverse osmosis filter in sequence. The outlet of the reverse osmosis filter is connected to the inlet of the pure water tank 2. A raw water pump 36 is also provided between the raw water tank 1 and the mechanical filter 31 to pump the water out of the raw water tank 1.

[0027] Please refer to Figure 2The circulation system 5 includes a circulation pump 51, a UV sterilizer 52, and a conductivity monitor 53. The pure water tank 2, the circulation pump 51, the UV sterilizer 52, and the conductivity monitor 53 are sequentially connected via a delivery pipe 54. Specifically, the inlet of the circulation pump 51 is connected to the outlet of the pure water tank 2, and the outlet of the circulation pump 51 is connected to the UV sterilizer 52 via the delivery pipe 54. The conductivity monitor 53 is installed on a section of the delivery pipe 54 at the outlet of the UV sterilizer 52, and the conductivity monitor 53 can monitor the conductivity of the water in the delivery pipe 54. A branch is formed at the end of the delivery pipe 54 away from the pure water tank 2, specifically forming a first branch pipe 541 and a second branch pipe 542, which are respectively connected to the delivery pipe 54. The first branch pipe 541 extends to communicate with the pure water tank 2, and a first solenoid valve 55 is provided on the first branch pipe 541. When the first solenoid valve 55 is open, the water in the delivery pipe 54 can flow out of the pure water tank 2, flow through the circulating delivery pump 51, the UV sterilizer 52, and the conductivity monitor 53 in sequence, and then flow back into the pure water tank 2 through the first branch pipe 541. This is the first circulation path. The second branch pipe 542 extends to communicate with the raw water tank 1, and a second solenoid valve 56 is provided on the second branch pipe 542. When the second solenoid valve 56 is open and the first solenoid valve 55 is closed, the water in the delivery pipe 54 can flow out of the pure water tank 2, flow through the circulating delivery pump 51, the UV sterilizer 52, and the conductivity monitor 53 once, and then flow back into the raw water tank 1 through the second branch pipe 542. This is the second circulation path.

[0028] Furthermore, this device also includes an ozone concentration monitor 57 and a PEM ozone device 58. The PEM ozone device 58 is mounted on the pure water tank 2 and communicates with the interior of the pure water tank 2 to adjust the ozone concentration in the pure water tank 2. The ozone concentration monitor 57 is mounted on the delivery pipe 54 to monitor the ozone concentration in the water flowing out of the pure water tank 2. This device also includes a control system (not shown in the figure), and the conductivity monitor 53, the first solenoid valve 55, the second solenoid valve 56, the ozone concentration monitor 57, and the PEM ozone device 58 are all signal-connected to the control system. The control system can control the opening or closing of the first solenoid valve 55 and the second solenoid valve 56. The conductivity monitor 53 can send the detected conductivity signal to the control system. The control system controls the first solenoid valve 55 to open and the second solenoid valve 56 to close, or the first solenoid valve 55 to close and the second solenoid valve 56 to open, according to the signal from the conductivity monitor 53. In this way, water can flow to the pure water tank 2 through the first branch pipe 541, or to the raw water tank 1 through the second branch pipe 542.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5Furthermore, in the above structure, the UV sterilizer 52 includes a base 521 and a water pipe 522, which is detachably connected to the base 521. Specifically, the base 521 is provided with fixing members 523 for fixing the water pipe 522. There are two fixing members 523, which are symmetrically arranged at both ends of the base 521 to cooperate in fixing the water pipe 522. Each set of fixing members 523 includes a sliding rod 5231. The upper end of the base 521 is recessed downward to form a sliding groove 524 for mounting the sliding rod 5231. Each sliding rod 5231 is perpendicular to the base 521, and the lower end of the sliding rod 5231 extends into the corresponding sliding groove 524 and can slide within the sliding groove 524 along the length direction of the base 521. An elastic element 5232 is provided between the side of the slide rod 5231 away from the other slide rod 5231 and the corresponding sidewall of the slide groove 524 to drive the slide rod 5231 to elastically return to its original position. In the illustrated embodiment, the elastic element 5232 is a helical spring, with one end fixedly connected to the slide rod 5231 and the other end fixedly connected to the corresponding sidewall of the slide groove 524. In other embodiments, the elastic element 5232 can also be other elastic elements 5232 such as spring sheets, as long as it can achieve the function of driving the slide rod 5231 to elastically return to its original position. The upper end of each slide rod 5231 is provided with a fixing cap 5233 for connecting to the end of the water pipe 522, and the openings of the two fixing caps 5233 are arranged opposite each other. The inner diameter of the fixing cover 5233 matches the outer diameter of the water pipe 522. The inner circumferential wall of the fixing cover 5233 is provided with an internal thread 5234. The helical directions of the internal threads 5234 on the two fixing covers 5233 are opposite. The end of the water pipe 522 is provided with external threads 5235 that respectively match the two sections of the internal threads 5234. A water passage hole 5236 is formed on the fixing cover 5233 to allow water to flow into or out of the water pipe 522 through the water passage hole 5236.

[0030] One embodiment of the water quality control device of this utility model operates as follows: In use, water first enters the raw water tank 1. Under the action of the raw water pump 36, the water flows out of the raw water tank 1 and passes through the mechanical filter 31, the activated carbon filter 32, the softening filter 33, the precision filter 34, and the reverse osmosis device 35. After undergoing multiple filtration processes, the water flows into the pure water tank 2. The water in the pure water tank 2 then enters the UV sterilizer 52 under the action of the circulating pump 51 for sterilization. It is important to emphasize that the user sets the target conductivity value through the control system. The conductivity monitor 53 sends the detected conductivity value signal of the water in the delivery pipe 54 to the control system. The control system compares this monitored value with the set value. If the monitored value is less than the set value, it indicates that the water quality meets the requirements. At this time, the control system sends a signal to open the first solenoid valve 55 and close the second solenoid valve 56. The water flows back to the pure water tank 2 through the first branch pipe 541 to start a new cycle. (It should be noted that when it is necessary to clean the endoscope with water, the user...) Water is drawn from the device through the water inlet 4 for cleaning. When cleaning the endoscope is not required, the water inlet 4 is closed, but the water is still circulating. If the monitored value is greater than the set value, it indicates that the impurities in the water exceed the standard and the water quality does not meet the requirements. At this time, the control system sends a signal to open the second solenoid valve 56 and close the first solenoid valve 55. The water flows back to the original water tank 1 through the second branch pipe 542 to be purified again by the water purification system 3. After purification, it flows back into the pure water tank 2 to participate in the circulation. In this way, the water quality used for cleaning the endoscope can always be good.

[0031] The UV sterilizer 52 has two conduits at both ends forming water passages 5236, both of which can be connected to the delivery pipe 54 to form a passage. The water passage pipe 522 can be separated from the base 521, which facilitates the user to clean or repair the water passage pipe 522 and the base 521 separately. When it is necessary to install the water passage pipe 522 on the base 521, the two fixing members 523 are moved away from each other to create sufficient space for the water passage pipe 522 to be inserted. At this time, the two elastic members 5232 are compressed. When the water passage pipe 522 is inserted between the two end caps, the force applied to the two fixing members 523 is released. Under the rebound force of the two elastic members 5232, the two end caps are retracted towards the water passage pipe 522 and contact the two ends of the water passage pipe 522. The water passage pipe 522 is rotated so that the two end caps are screwed onto the two ends of the water passage pipe 522. To remove the water pipe 522, simply reverse the steps described above.

[0032] Compared with existing technologies, this utility model's water quality control device achieves highly efficient sterilization and microbial control of circulating water through the synergistic effect of a PEM ozone device and a UV sterilizer. Simultaneously, the device has the function of real-time monitoring of ozone concentration and conductivity, automatically adjusting the ozone concentration and optimizing water quality to ensure the hygiene, safety, and stability of the circulating water. This technology has advantages such as intelligence, energy saving, environmental protection, and stable operation, significantly improving the efficiency and reliability of circulating water treatment systems.
