At present, people purchase purified water products mainly in several aspects: filtration process, water flow, waste water ratio, etc. There is also a great variation in tap water pressure at different times in the same place due to the difference in tap water pressure at no place. Because the water pressure is low, many people are always dissatisfied with the water outlet flow when using the water purifier, the general flow is smaller, and a long time is needed to wait for a cup of water.
There is a solution on the market for this: the water purifier is matched with the pressure barrel. Thus, the stability of the water outlet flow is ensured. However, this also brings about a great negative problem: the pressure barrel is a warm bed for bacteria breeding. Moreover, since the pressure barrels are generally provided at the ends, the water received by the user is often rich in bacteria, some of which are even tens or hundreds times more than bacteria in tap water.
In addition, low water pressure is a problem, and excessive water pressure is a common problem. For example, in Chongqing areas, due to the uniqueness of the geographic position, the tap water pressure is particularly high, and the tap water pressure in some areas is even higher than 1.2MPa set by the pressure maintaining test of the water purifier products. Under such pressure, the safety of the water purifier product is a great test. Some products have a large number of water leakage accidents.

The primary filter module 1 can filter out large particle impurities, and the primary filter module 1 in the embodiment can be one or a combination of more than one of a PP cotton filter element, an active carbon filter element, a micro-filtration membrane filter element and an ultrafiltration membrane filter element.
The water storage barrel 3 is provided with an exhaust port 34, a first liquid level sensor 31, a second liquid level sensor 32 and a third liquid level sensor 33 are sequentially arranged in the water storage barrel 3 from high to low, a water quality monitoring sensor 35 is further arranged in the water storage barrel 3, and the third liquid level sensor 33 and the water quality monitoring sensor 35 are arranged close to the bottom wall of the water storage barrel 3.
The water inlet end of the water storage barrel 3 is connected with the water outlet end of the primary filter module 1 through a first pipeline 51, and a first electromagnetic valve 61 is arranged on the first pipeline 51; the water storage barrel 3 is externally connected with a drain pipe 56, a fourth electromagnetic valve 66 electrically connected with the third liquid level sensor 33 is arranged on the drain pipe 56, and the fourth electromagnetic valve 66 is also electrically connected with the water quality monitoring sensor 35.
The secondary filter module 2 can filter out small particle impurities, and the secondary filter module 2 in the embodiment can be one or a combination of more than one of a nanofiltration membrane filter element and a reverse osmosis membrane filter element.
The water inlet end of the secondary filter module 2 is connected with the first water outlet end of the water storage barrel 3 through a second pipeline 52, a water pump 62 is arranged on the second pipeline 52, the wastewater outlet end of the secondary filter module 2 is connected with the water storage barrel 3 through a third pipeline 53, and a second electromagnetic valve 63 is arranged on the third pipeline 53.
The water inlet end of the water outlet valve 7 is connected with the purified water outlet end of the secondary filter module 2 through a fourth pipeline 54, and a Hall sensor which is electrically connected with the water pump 62 is arranged on the water outlet valve 7 and is not shown in the figure; the water outlet valve 7 in this embodiment may be a faucet with a built-in hall sensor, and the water pump 62 is a self-priming water pump.
The high end of the fifth pipeline 55 is connected with the fourth pipeline 54, the low end is connected with the water storage barrel 3, and a third electromagnetic valve 65 is arranged on the fifth pipeline 55;
the first liquid level sensor 31 and the second liquid level sensor 32 are electrically connected with the first solenoid valve 61.
The water quality monitoring sensor 35 in this embodiment may be one or more of a TDS monitoring head and an organic matter sensor.
Tap water is subjected to coarse filtration by the primary filter module 1, and large-particle impurities such as sediment, rust, colloid and the like are filtered out. The first solenoid valve 61 controls tap water to enter the water storage tub. When the first level sensor is triggered, the first solenoid valve 61 is closed. When the water outlet valve 7 is opened, a Hall sensor is triggered to control the water pump 62 to start. The water pump 62 sucks water from the water storage tub 3. When the second level sensor 32 is triggered, the first solenoid valve 61 is opened and tap water is fed.
After each water taking, the first electromagnetic valve 61 is opened until the first liquid level sensor 31 is triggered, so that the water taking process can be smoothly performed each time, and the phenomenon that the water outlet flow is too small or water cannot be discharged due to insufficient water in the water storage barrel 3 is prevented.
When the water is taken, a section of clean water, namely water on the fourth pipeline 54, exists between the secondary filter module 2 and the water outlet valve 7. When a general user takes water each time, worrying about bacterial growth of water on the section of pipeline, the water outlet valve 7 can flow for a period of time before taking water, and then water is received. This process is wasteful of water. In this embodiment, it is necessary to drain the water between the secondary filter module 2 and the water outlet valve 7 in advance, or to reuse the water in advance. On one hand, water resources are saved, on the other hand, bacteria are prevented from breeding, and on the other hand, the system is prevented from being broken and leaking water caused by pipeline icing in winter.
The control mode is as follows: when water taking is finished each time, after the water outlet valve is closed, the Hall sensor is triggered, and the water pump stops running. The third solenoid valve 65 is then opened, and gravity is used to flow water between the secondary filter module 2 and the water outlet valve 7 into the water storage tub 3.
The waste water rate of the secondary filter module 2 is too high. In practice, the wastewater discharged from the wastewater outlet corresponds to the concentration of tap water, and a lot of available water still exists in the wastewater outlet. The waste water port of the secondary filter module 2 is connected to the water storage barrel 3 and is mixed with tap water for reuse.
The water quality monitoring sensor 35 in this embodiment only adopts a TDS monitoring head, and its control method is as follows: when the TDS monitoring head detects that the TDS > a value of water in the water storage barrel (for example, the a value is set to 800), the water draining treatment is judged to be needed. The first solenoid valve 61 is closed (water is prevented from being wasted), the water pump 62 is stopped, and the third solenoid valve 65 is closed. The fourth solenoid valve 66 is opened and water is drained. When the third level sensor 33 is triggered, the fourth solenoid valve 66 is closed. The first solenoid valve 61 opens the inlet water. When the second level sensor 32 is triggered, the water intake process is continued.
In addition, the value a can be set to different values according to different places, such as a region with smaller TDS of tap water, and the value a can be set to be smaller (such as the value a is set to 400), so that water is saved, and meanwhile, the service life of the filter element is prevented from being reduced due to long-time filtration of a water source with a high TDS value.
The water quality monitoring sensor 35 in this embodiment may be combined with an organic matter sensor, and double-control the wastewater discharge time through organic matter detection and TDS detection.
Embodiment 2, as shown in fig. 2, in this embodiment, no first level filter module is disposed, no first level sensor is disposed in the water storage tank 3, and other structures and operations refer to embodiment 1. When the liquid level triggers the second liquid level sensor 32, an alarm device may be provided to prompt the user to add water.
