Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a pure water machine structure. Background Technology

[0002] A water purifier is a water purification device that uses multi-stage filter cartridges to purify water. It uses reverse osmosis or ultrafiltration technology to apply pressure to the water, allowing water molecules and some minerals to pass through a special semi-permeable membrane, while pollutants, bacteria, viruses and other contaminants are trapped on the other side of the membrane, thereby achieving the purpose of purifying the water.

[0003] Currently, water purifiers on the market use leak alarms to warn of leaks. If a problem occurs, the water inlet solenoid valve is shut off to disconnect the water supply. However, the water inlet of the water purifier is not controlled. If the leak is located at the front end of the water inlet solenoid valve, the product will continue to leak. This makes it impossible to deal with the leak in time, resulting in large-scale leaks and potentially serious accidents.

[0004] Most water purifiers on the market do not have a zero-stagnant-water function, which results in poor water quality for the first cup of water when not in use, thus affecting the user experience.

[0005] Although water purifiers with reflux valves have emerged, most lack IoT (Internet of Things) functionality. This is because switching on and off the zero-stagnant-water function requires bending down to the machine under the kitchen or bathroom, resulting in a poor user experience. Furthermore, leaks cannot be reported to customers promptly, making it impossible to anticipate product status immediately.

[0006] Therefore, there is an urgent need for a water purifier structure that can solve the leakage problem of water purifiers from the water inlet, optimize the reverse osmosis of the RO membrane, and improve the user experience. Utility Model Content

[0007] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0008] The technical problem to be solved by this utility model is to provide a water purifier structure that can solve the water leakage problem of the water purifier from the water inlet source, optimize the reverse osmosis of the RO membrane, and improve the user experience.

[0009] To solve the above-mentioned technical problems, the present invention provides a pure water machine structure comprising:

[0010] The water inlet control component 1 has its inlet connected to the water inlet end and its outlet connected to the water inlet of the first filter unit 2;

[0011] The outlet of the first filter unit 2 is connected to the inlet of the booster pump 4 via the first valve 3.

[0012] Booster pump 4, whose outlet is connected to the inlet of the second filter unit 5;

[0013] The outlet of the second filter unit 5 is connected to the inlet of the third filter unit 8 after passing through the second valve 6 and the switch 7 in sequence. Its outlet is also connected to the inlet of the booster pump 4 after passing through the third valve 9, the fourth valve 10, and the fifth valve 11 in sequence.

[0014] The third filter unit 8 has its outlet connected to the water supply end;

[0015] The fourth valve, 10, is a normally closed valve;

[0016] The sensor, located at the water-using end, detects water usage. If no water usage is detected again after a first delay, it sends a first electrical signal to trigger the opening of the fourth valve 10 and the start of the booster pump 4. After a second delay, it sends a second electrical signal to trigger the closing of the fourth valve 10 and the shut-off of the booster pump 4.

[0017] Preferably, in a further improvement to the structure of the pure water machine, the water inlet control component 1 includes:

[0018] The electric inlet three-way ball valve 1.1 has its inlet connected to the inlet end and its outlet connected to the inlet of the low-pressure switch 1.2. It has a geared motor.

[0019] The low-pressure switch 1.2 has its outlet connected to the inlet of the first filter unit 2.

[0020] Preferably, in a further improvement to the structure of the pure water machine, the first filtration unit 2 includes:

[0021] The first polypropylene meltblown filter element 2.1, the carbon rod filter element 2.2, and the second polypropylene meltblown filter element 2.3 are connected in series.

[0022] Preferably, in a further improvement to the structure of the pure water machine, the first valve 3 and the fourth valve 10 are solenoid valves.

[0023] Preferably, the structure of the pure water machine is further improved in that the second valve 6, the third valve 9, and the fifth valve are check valves.

[0024] Preferably, in a further improved version of the pure water machine structure, the second filtration unit 5 is a reverse osmosis membrane.

[0025] Preferably, in a further improvement to the structure of the pure water machine, the third filtration unit 8 is an activated carbon filter element.

[0026] Preferably, the structure of the pure water machine is further improved by including:

[0027] The combined solenoid valve 12 is connected to the concentrate outlet of the second filter unit 5.

[0028] The working principle and technical effects of this utility model are as follows;

[0029] This invention enables zero-stagnant-water functionality. Under normal water supply conditions, the return water solenoid valve is normally closed. If the customer does not use the water supply again after a certain period (e.g., five minutes), it is assumed that the customer has stopped using the water supply. Therefore, opening the return water solenoid valve starts the machine. At this time, RO water will return to the pump through the return solenoid valve. After a certain period of energization, the RO water and raw water are mixed together, lowering the influent water quality. During this time, the TDS value of the water before the RO membrane is reduced through mixing. Then, the pump and the return water solenoid valve are closed. When the machine is not in use, the water quality before the RO membrane is far superior to normal water quality. Even with reverse osmosis, the TDS value is less than one-third of the original value. Combined with the downstream activated carbon filtration, since the TDS of the return water is already lower than normal during the initial return water run, a certain amount of water with lower TDS is stored in the activated carbon filter chamber. When the customer uses the water supply, the water participating in reverse osmosis will flow back into the activated carbon filter, mixing before being discharged. Based on the mixing ratio, this ensures that the discharged water still meets the standard water quality requirements. Furthermore, this invention can circulate the machine periodically while in zero-stagnant-water mode to ensure the freshness of the water. During use, the product has IoT functionality, allowing users to manually turn the zero-stagnant-water function on and off via an app, catering to diverse needs and different usage scenarios.

[0030] This invention uses an electric inlet three-way ball valve for water inlet control, and the electric inlet three-way ball valve employs a geared motor. Under normal use, the geared motor uses a gear transmission principle to rotate the ball valve. According to the electrical control command, it controls the ball valve's switch, thus meeting the customer's usage environment requirements. Using a gear transmission principle, there is no overheating phenomenon during long-term use; rotation stops after reaching a certain torque resistance. By adjusting the current in either direction as needed, the ball valve can be controlled to switch in either direction to meet different customer usage environments. Furthermore, if the machine leaks, the ball valve can be directly closed, completely eliminating the problem of blind spots in the leak detection. The system can also remotely alert the customer via an app, ensuring the safety of the customer's property. Attached Figure Description
