Description
Technical Field
[0001] This utility model relates to the field of water purifier technology, specifically to an ultrapure water storage device. Background Technology
[0002] Pure water, also known as UP water, refers to water with a resistivity of 18 MΩ*cm (25℃). This type of water contains virtually no impurities other than water molecules; it is water from which almost all atoms except oxygen and hydrogen have been removed. Ultrapure water can be used in the preparation of ultrapure materials (semiconductor components, nano-fine ceramic materials, etc.) through distillation, deionization, reverse osmosis, or other appropriate supercritical fine technologies. Due to its extremely high purity, ultrapure water contains almost no inorganic salts or organic matter, making it highly susceptible to contamination and difficult to store and transport over long distances.
[0003] In existing ultrapure water storage devices, it is often impossible to disassemble the storage device for cleaning. Long-term use will make it impossible to guarantee the hygienic environment inside the device, thus causing ultrapure water contamination.
[0004] In view of this, there is an urgent need to provide a technical solution to the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-generated ultrapure water storage device. This storage device is detachable, allowing for a more thorough cleaning of its internal components and further ensuring the purity of the ultrapure water remains uncontaminated. To solve the aforementioned technical problems, this invention adopts the following technical solution:
[0006] An ultrapure water storage device includes an ultrapure water tank body and a tank cover. The ultrapure water storage device includes a supply water tank, which comprises a tank body for storing ultrapure water and a tank cover attached to the tank body. The tank cover is equipped with a UV germicidal lamp for sterilizing the ultrapure water inside the tank body. This device, with its tank body and tank cover, allows for disassembly for deep cleaning and subsequent resealing. This device ensures overall airtightness while making tank cleaning more convenient and thorough, thus helping to maintain the purity of the ultrapure water and prevent contamination.
[0007] As an improvement to the ultrapure water storage device of this utility model, the water tank cover is axially provided with an ultrapure water input interface and a UV sterilization lamp mounting port, and the UV sterilization lamp is installed in the UV sterilization lamp mounting port. The UV sterilization lamp can further sterilize and disinfect the ultrapure water in the storage device, further improving the purity of the ultrapure water.
[0008] Furthermore, a flow-limiting orifice is provided on the inner bottom of the ultrapure water input interface. The flow-limiting orifice allows ultrapure water to be continuously input into the water supply tank in a basically dripping state, enabling water production and use simultaneously. This ensures both normal water output and use while maintaining the freshness of the supplied ultrapure water, reducing the impact of secondary pollution on water quality.
[0009] Preferably, the outer wall of the water tank cover is provided with an installation groove, and a sealing ring is built into the installation groove. The water tank cover is sealed to the water tank body through the sealing ring.
[0010] As an improvement to the ultrapure water storage device of this utility model, a side wall groove is provided on the side of the water tank body, and a water level control module for detecting the ultrapure water level inside the water tank body is installed in the side wall groove. The sealing ring can improve the airtightness of this ultrapure water storage device and prevent external air from entering the tank and causing ultrapure water contamination.
[0011] Preferably, the groove on the side wall of the water tank is provided with a plurality of mounting holes for the water level control module. The water level control module is inserted into the mounting holes and fits into the groove on the side wall of the water tank. The mounting holes make the installation of the water level control module on the side wall of the water tank more secure, further improving the durability of the device.
[0012] Furthermore, a boss is axially provided on the bottom of the water tank body, and a water outlet extends from the center of the boss in the opposite direction of the boss's projection. This boss design ensures that the water outlet is not located at the bottom of the water tank body, thus preventing the ultrapure water flowing from the outlet from being the water at the bottom of the tank. This further guarantees the purity of the ultrapure water used.
[0013] Preferably, the protrusion has a square cross-section, and the water outlet is cylindrical. The square protrusion creates a height difference between the water outlet and the bottom of the water tank, further ensuring the purity of the ultrapure water flowing out of the outlet.
[0014] Preferably, a cleaning drain outlet is provided between the protrusion and the interior of the water tank body. When cleaning the water tank, the cleaning drain outlet needs to be blocked to prevent water from flowing out. After cleaning, simply open the cleaning drain outlet to let the water flow out. This design makes cleaning the water tank more convenient.
[0015] Preferably, the cleaning drain outlet is fitted with a removable soft rubber plug. The soft rubber plug can be used to block or release the cleaning drain outlet, preventing water leakage during water tank cleaning.
[0016] The beneficial effects of this utility model are as follows: the ultrapure water storage device of this application facilitates deep cleaning of the inside of the water tank, ensures a hygienic environment inside the device, avoids technical problems that cause ultrapure water pollution, and keeps the output ultrapure water fresh and pure.

[0030] This application provides an ultrapure water storage device, including an ultrapure water tank body 211 and a water tank cover 212. The ultrapure water storage device 2 includes a water supply tank 21, which includes a water tank body 211 for storing ultrapure water and a water tank cover 212 attached to the water tank body 211. The water tank cover 212 is equipped with a UV germicidal lamp 22 for sterilizing the ultrapure water inside the water tank body 211.
[0031] This device has a water tank body 211 and a water tank cover 212, allowing the ultrapure water storage device 2 of this invention to be disassembled for deep cleaning. This invention solves the problem that existing ultrapure water storage devices often make the cleaning process very complicated and the cleaning effect unsatisfactory due to the need for airtightness. This device makes the cleaning of the water tank more convenient and thorough while ensuring overall airtightness, which helps to ensure that the ultrapure water is pure and not contaminated.
[0032] Please refer to further information. Figure 2-3 In some embodiments, the water tank cover 212 is axially provided with an ultrapure water inlet 2121 and a UV germicidal lamp mounting port 2124, with the UV germicidal lamp 22 installed in the UV germicidal lamp mounting port 2124. The ultrapure water to be stored enters the water tank body 212 through the ultrapure water inlet 2121. The ultrapure water in the water tank body 211 is further sterilized and disinfected by the UV germicidal lamp 22 installed in the UV germicidal lamp mounting port 2124.
[0033] In some embodiments, a flow-limiting orifice 2122 is provided on the inner bottom of the ultrapure water input interface 2121. The flow-limiting orifice 2122 allows the ultrapure water to be continuously input into the water supply tank 21 in a drip state, which can realize water production and use at the same time.

[0034] Please refer to further information. Figure 3 In some embodiments, the outer wall of the water tank cover 212 is provided with a mounting groove 2126, and a sealing ring 24 is built into the mounting groove 2126. The water tank cover 212 is sealed to the water tank body 211 through the sealing ring 24. The sealing ring 24 on the outer side of the water tank cover 212 ensures the airtightness of the entire device after sealing the water tank cover 212 to the water tank body 21, preventing outside air from entering the device and contaminating the ultrapure water.
[0035] Please refer to further information. Figure 2-3 In some embodiments, a side wall groove 2114 is provided on the side of the water tank body 211, and a water level control module 23 for detecting the level of ultrapure water inside the water tank body 211 is installed in the side wall groove 2114. The side wall groove 2114 makes the installation of the water level control module 23 more secure. When the water level control module 23 detects that the water level in the water supply tank 21 is low, it sends a signal to the main control board, and the main control board delivers ultrapure water to the water supply tank 21. Conversely, when the water level control module 23 detects that the water level in the water supply tank 21 is high, it sends a signal to the main control board, and the main control board will control the stopping of the delivery of ultrapure water. This ensures that the water inside the water supply tank 211 meets the requirements for output and use, but does not remain for too long, thus ensuring the freshness of the water quality.
[0036] Preferably, the side wall groove 2114 of the water tank is provided with a plurality of water level control module mounting holes 2115. The water level control module 23 is inserted into the water level control module mounting holes 2115 and is fitted and covered by the side wall groove 2114 of the water tank. The water level control module mounting holes 2115 make the water level control module 23 more securely fixed and enhance the durability of the device.
[0037] Please refer to further information. Figure 2 In some embodiments, a boss 2111 is axially provided at the bottom of the water tank body 211, and a water outlet 2112 extends from the center of the boss 2111 in the opposite direction to the protrusion of the boss 2111. The water outlet 2112 extending from the boss 2111 in the opposite direction to the protrusion ensures that the outflowing water is not the water flow at the bottom of the water tank body 21, further guaranteeing the purity of the outflowing ultrapure water.
[0038] Typically, the boss 2111 has a square cross-section, and the water outlet 2112 is cylindrical.

The cleaning drain outlet 2113 is located at the bottom of the water tank body 211. When cleaning and draining, all the water in the water tank can be drained to avoid contamination of the ultrapure water.
[0040] Preferably, the cleaning drain outlet 2113 is equipped with a removable soft rubber plug. During cleaning, the soft rubber plug is inserted into the cleaning drain outlet 2113, and when cleaning is complete, the soft rubber plug is removed to drain the water. The soft rubber plug has good sealing properties, which can prevent water leakage during the cleaning process.
[0041] Using this embodiment to store ultrapure water:
[0042] The ultrapure water to be stored flows into the tank body 211 from the ultrapure water inlet 2121 through the flow restrictor 2122. The water level control module sends a signal to the main control board to control whether ultrapure water continues to be added to the tank body 211. The bottom of the tank body 211 has a protrusion 2111, with the outlet 2112 extending in the opposite direction. When the stored ultrapure water is needed, it flows out from the outlet 2112.
