Description

A highly intelligent pure water machine

technical field

Therefore, the current tap water in China is not suitable for direct drinking , must be purified by a pure water machine or filter before drinking. As water pollution becomes more and more serious, the quality problems of domestic tap water suppliers have been repeatedly exposed.

Since the hardness (TDS value) of tap water in southern and northern China is very different (ranging from 80-1500), and the replacement filter element of the pure water machine on the market is reminded by a fixed use time, there are many problems in this way. Big question. First, if the user’s water consumption is small or the water quality in the user’s location is good, replacing the filter element within a fixed time will cause incomplete utilization of the filter element, resulting in waste; second, if the user’s water consumption is large or the user’s location When the water quality is very poor, it will cause the filter element to fail early, so that polluted water will be used, and the purpose of water purification will not be achieved.

Generally, the amount of polluted water Around 50-100ml. Since the general pure water machine is not equipped with a detection device, the user does not know that the water quality is polluted by the RO membrane immersion membrane when using it, especially when the user’s water consumption is small each time, it will cause the user to repeatedly use the contaminated immersion membrane Water cannot guarantee the safety of water for users, and the pure water machine has lost its original meaning of water purification.

detailed description

In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, not to limit the utility model.

Example 1:

With reference to shown in Fig. 1-9, the highly intelligent pure water machine that the utility model provides, comprises single-chip microcomputer intelligent control system, pressure control system, water quality detection system, water quality purification system, water flow control system and pipeline, described pressure control system, water quality The detection system, the water quality purification system, and the water flow control system are connected through pipelines, and the pressure control system, water quality detection system, water quality purification system, and water flow control system are respectively connected with the single-chip intelligent control system, and the single-chip intelligent control system is provided with an LED display interface 11 and voice alarm prompting device 12. The pressure control system includes a water inlet pressure detection sensor 21, a pure water pressure detection sensor 22, a booster pump 23 and a water storage pressure tank 24; the water quality detection system includes a raw water quality detection sensor 31 and a pure water quality detection sensor 32. The water purification system includes a pre-filter ultrafiltration device 41, an RO membrane 42 and a post-filter device 43; the water flow control system includes a water inlet switch 51, a water inlet solenoid valve 52, and a first one-way valve 531, second one-way valve 532, third one-way valve 533, blocking solenoid valve 54, produced water flow detection sensor 55, sewage solenoid valve 56, waste water solenoid valve 57, membrane water drainage solenoid valve 58 and drainage water Solenoid valve 59.

During work, connect the 24V DC power supply to the high-intelligence pure water machine, turn on the water inlet switch 51, the equipment automatically detects the raw water information, and starts working automatically. If the tap water is not turned on or the tap water pressure is not enough, the water inlet pressure detection sensor 21 detects no water information, and the LED display interface 11 will display water shortage, the raw water TDS value and the purified water TDS value are both displayed as 0PPM, and the machine is in a static state. as shown in picture 2.

When the water inlet switch 51 is turned on, the inlet water pressure detection sensor 21 detects raw water information, and the raw water passes through the raw water quality detection sensor 31 and then enters the pre-filter element ultrafiltration device 41 through the water inlet solenoid valve 52, at this time, the solenoid valve 54 is blocked , the discharge water solenoid valve 59, the row immersion membrane water solenoid valve 58 and the waste water solenoid valve 57 are closed. The machine enters the blowdown state for ten seconds and the flushing state for two minutes, and the pollutants intercepted by the pre-filter element ultrafiltration device 41 are discharged from the blowdown solenoid valve 510 and rinsed away. Through the single-chip intelligent control system connected with the raw water quality detection sensor 31, the real-time TDS value of the raw water is fed back to the LED display interface 11. At this time, the LED display interface 11 displays the TDS value of the raw water and the high TDS value of the purified water, as shown in the figure 3.

Two minutes later, the high-intelligence pure water machine enters the water production state. Within one minute of the start of water production, the sewage solenoid valve 510, the waste water solenoid valve 57, the differential water solenoid valve 59 and the blocking solenoid valve 54 are closed, and the immersion membrane water is discharged. Electromagnetic valve 58 is opened, and due to the effect of the first one-way valve 531, water can not flow backwards, and at this moment, the polluted water of immersion membrane can enter in the waste water pipeline and be discharged through the electromagnetic valve 58 of drainage immersion membrane water. A second one-way solenoid valve 532 is arranged between the valves 58 to avoid cross-contamination caused by waste water and pure water when the solenoid valve 58 is opened and closed. After one minute, the membrane water solenoid valve 58 is closed, the solenoid valve 54 is blocked, and the equipment enters the normal water production state, and the qualified pure water produced enters the water storage pressure tank 24 for storage, as shown in Figure 5; Figure 4 shows the state of water quality for rinsing with polluted water of the immersion membrane.

After a period of time, the pressure in the water storage pressure barrel 24 rises with the increase of water production, and when the pure water pressure detection sensor 22 detects that the pressure reaches the highest set value, a water full signal is given, and the LED display interface 11 shows that the water is full. , the machine stops working at this time, as shown in Figure 6.

When the user uses water, the pressure in the water storage pressure barrel 24 drops, and when the pressure detected by the pure water pressure detection sensor 22 drops to the lowest set value, the water production state is re-entered, and the whole process is automatically completed.

When the raw water quality detection sensor detects the raw water TDS value (take the average value of 0.1 tons of water), it will be fed back to the single-chip intelligent control system, and the system will set the parameters according to the size of the RO membrane 42, so that RO can be calculated according to the raw water quality. The prefabricated water volume of the membrane 42, when the user’s water production is close to or exceeds 90% of the prefabricated water volume, the system prompts to replace the RO membrane, as shown in FIG.

When the TDS value detected by the pure water quality detection sensor is higher than the set value (set to 10PPM according to the country’s requirements for bottled water), the LED display interface 11 will display poor water quality, and an alarm will be given through the voice alarm prompt device 12, as shown in the figure 8. At this time, the blocking solenoid valve 54, the waste water solenoid valve 57, the soaking membrane water solenoid valve 58 and the blowdown solenoid valve 510 are closed, the drain water solenoid valve 59 is opened, and the unqualified pure water is discharged into the waste water through the drain water solenoid valve 59 In the pipeline, generally as long as the RO works normally, the normal TDS value can be restored within 5-10 minutes. At the same time, a third one-way valve 533 is also arranged between the waste water pipeline and the differential water solenoid valve 59 to avoid cross-contamination caused by waste water and pure water when the differential water solenoid valve 59 is opened and closed.

When the adjustment time of the above-mentioned discharge water exceeds the upper limit time (60 minutes) of the adjustment setting, and still cannot produce qualified pure water, it means that the RO membrane has been damaged, prompting to replace the RO membrane, and the whole equipment stops working. At this time, the LED display interface The status is shown in Figure 9.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present utility model shall be included in the present utility model. within the scope of the new protection.
