Description

Technical Field

[0001] This utility model belongs to the field of ultrapure water machine technology, specifically a high-efficiency and energy-saving laboratory ultrapure water machine. Background Technology

[0002] An ultrapure water system is a water treatment device that uses pretreatment, reverse osmosis technology, ultrapure water treatment, and post-treatment methods to almost completely remove conductive media from water, and also removes non-dissociated colloidal substances, gases, and organic matter to very low levels. Ultrapure water systems are also known as: ultrapure water purifiers, ultrapure water equipment, ultrapure water instruments, ultrapure water systems, laboratory ultrapure water systems, etc.

[0003] Currently available ultrapure water systems, if not used for extended periods, leave the ultrapure water in a stagnant state within the equipment's pipelines. This causes a decline in water quality. Consequently, the resistivity of the initial ultrapure water drawn is very low and does not meet experimental requirements. The water quality only improves during the initial drawing process to meet usage requirements. Consequently, the initial ultrapure water drawn is often discarded. However, in practical applications, it is uncertain how much ultrapure water will be drawn to meet usage needs, potentially leading to water waste and reduced utilization of equipment consumables. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient and energy-saving laboratory ultrapure water system in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A high-efficiency and energy-saving laboratory ultrapure water system includes an ultrapure water system body. Inside the ultrapure water system body, there is a PCB board and a pretreatment module, a reverse osmosis module, and a storage tank connected in sequence.

The water outlet end of the water outlet end is detachably equipped with a protective component. The water outlet end of the storage tank is provided with a pumping component for extracting pure water. The water outlet end of the pumping component is equipped with a water flow channel. A water quality sensor in contact with water is provided on the water flow channel. An electric three-way valve is connected between the end of the water flow channel and the water outlet end. The other end of the electric three-way valve is connected to the reverse osmosis module through a return pipe. The electric three-way valve and the pumping component are both controlled by the PCB board.

[0006] In a preferred embodiment, the protective component includes a protective cover and a connecting strap. The bottom end of the water outlet is recessed inward to form a plurality of positioning grooves. The protective cover has a receiving cavity with a top opening. The top wall of the protective cover protrudes to form a plurality of positioning protrusions that allow for interference fitting into the positioning grooves.

[0007] In a preferred embodiment, the top of the positioning protrusion is provided with a spherical arc surface, and the width of the positioning protrusion gradually decreases from bottom to top.

[0008] In a preferred embodiment, the connecting strap is made of a soft material, with one end of the connecting strap fitted onto the protective cover and the other end fixed to the ultrapure water unit.

The water can then be re-treated by the reverse osmosis module and discharged back into the storage tank. This can reduce the waste of water resources and monitor the quality of the extracted ultrapure water in real time. It is highly efficient and energy-saving, and can also ensure the accuracy of subsequent experiments.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] Reference Figure 1-3 A high-efficiency and energy-saving laboratory ultrapure water system includes an ultrapure water unit 3 (externally powered or powered by AC mains). Inside the ultrapure water unit 3, there is a PCB board 17 and a pretreatment module 1, a reverse osmosis module 2, and a storage tank 9 connected in sequence. The pretreatment module 1 includes multiple filter elements, activated carbon filter elements, etc., for pretreatment of water. The reverse osmosis module 2 includes a purification column, a reverse osmosis membrane, etc. Through pretreatment and reverse osmosis treatment of tap water, water can be converted into ultrapure water. The converted ultrapure water can be stored in the storage tank 9. Since the pretreatment and reverse osmosis technologies in the ultrapure water system are known, the specific structure and connection method will not be described in detail here.

[0021] Reference Figure 2 As shown, the ultrapure water unit 3 has an outlet head 4 connected to the storage water tank 9 at its outer end. A protective component is detachably installed at the outlet end of the outlet head 4. The protective component includes a protective cover 13 and a connecting strap 14. The bottom end of the outlet head 4 is recessed inward to form several positioning grooves. The protective cover 13 has a receiving cavity with a top opening. The top wall of the protective cover 13 protrudes to form several positioning protrusions 15 that can be inserted into the positioning grooves with interference fit. The top of the positioning protrusions 15 has a spherical arc surface. The width of the positioning protrusions 15 gradually decreases from bottom to top. The protective component is detachably installed at the outlet end of the outlet head. When not in use, the protective cover 13 can be placed on the outlet head 4 to reduce the accumulation of external impurities or dust on the outlet head 4 when not in use, which can reduce the impact on water quality. Since the protective cover 13 and the outlet head 4 are connected by a snap-fit ​​method, installation and removal are also more convenient.

[0022] The outer shell of the water outlet 4 and the protective cover 13 is preferably made of plastic.

[0023] Furthermore, the connecting strap 14 is made of a soft material, preferably plastic. One end of the connecting strap 14 is fixed to the protective cover 13, and the other end of the connecting strap 14 is fixed to the ultrapure water body 3. The protective cover 13 and the ultrapure water body 3 can be combined together through the connecting strap 14 to avoid the loss of the protective cover 13 after disassembly.

[0024] Reference Figure 1 As shown, the water outlet of the storage tank 9 is equipped with a pumping component for extracting pure water. A water flow channel 12 is installed at the water outlet of the pumping component. A water quality sensor 6 is installed on the water flow channel 12, which is in contact with the water phase. An electric three-way valve 11 is connected between the end of the water flow channel 12 and the water outlet 4. The other end of the electric three-way valve 11 is connected to the reverse osmosis module 2 through a return pipe 7. The electric three-way valve 11 and the pumping component are both controlled by the PCB board 17. The water quality sensor 6 is designed on the water flow channel 12. The water quality sensor 6 can monitor the water quality of the extracted water in real time. When the water quality does not meet the standard, the electric three-way valve 11 is controlled by the PCB board 17 to connect the water flow channel 12 and the reverse osmosis module 2. The water can then be re-treated by the reverse osmosis module 2 and then discharged back into the storage tank 9. This can reduce the waste of water resources and monitor the quality of the extracted ultrapure water in real time. It is highly efficient and energy-saving, and can also ensure the accuracy of subsequent experiments by the experimental personnel.

[0025] Furthermore, a tray 5 is installed directly below the water outlet 4 on the ultrapure water unit 3. A maintenance cover is detachably installed on the side of the ultrapure water unit 3, and an inlet 16 connected to the pretreatment module 1 is also provided on the side of the ultrapure water unit 3. The ultrapure water unit 3 is also equipped with operation buttons and a display screen (not shown in the figure).

[0026] Furthermore, the return pipe 7 is equipped with a one-way valve 8 that can only flow from the electric three-way valve 11 into the reverse osmosis module 2. The one-way valve 8 is designed to prevent the backflow of substandard water.

[0027] Furthermore, the water pumping assembly includes a water pump 10, an electrically controlled valve, and an outlet pipe. The inlet end of the water pump 10 is connected to the storage tank 9, and both ends of the outlet pipe are connected to the water pump 10 and the electric three-way valve 11. The electrically controlled valve is installed on the outlet pipe. The water pump 10 can discharge ultrapure water from the storage tank 9 and then flow into the outlet head 4 for discharge, thus realizing the water extraction operation.

[0028] The end of the water outlet pipe facing the storage tank 9 can also be designed with a check valve that allows water to flow out of the storage tank 9 in only one direction.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
