The utility model sets the pH value detector behind the reverse osmosis or nanofiltration membrane filter element, and automatically closes the bypass electromagnetic valve and opens the pH value regulator when the pH value of the direct drinking water is measured to be lower by setting the range of the pH value detector, so that the water can reach alkalescence after mineralization treatment, and the taste is improved; when the direct drinking water is in the set range, the pH value regulator is closed, the bypass electromagnetic valve is opened, the bypass water flows out and directly enters the water tank, and the purposes of improving the taste of the discharged water and improving the quality of the direct drinking water are achieved.

Description

Household water purifier capable of automatically adjusting water outlet taste

Technical Field

The utility model relates to a water purification technology field especially relates to a but domestic water purifier of automatically regulated play water taste.

Background

The pH value of drinking water has great influence on human health, and a long-term drinking of weakly acidic water can induce various digestive tract diseases of a human body, while weakly alkaline water is beneficial to the metabolism of the human body. After the common household water purifier is filtered by an RO membrane or an NF membrane, the water quality becomes weak acid, the direct drinking water after direct drinking treatment has poor taste, and the demand of a human body for drinking neutral or weak alkaline water can not be met. In order to improve the pH value of the purified water, the invention provides the household water purifier capable of automatically adjusting the taste of the discharged water.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem existing in the background art, the utility model provides a but domestic water purifier of automatically regulated play water taste.

The utility model provides a but domestic water purifier of automatically regulated play water taste, its characterized in that, includes the water inlet that communicates in proper order, the electromagnetic valve of intaking, the cotton filter core of PP, granule active carbon filter core, compression active carbon filter core, booster pump, reverse osmosis or receive and strain membrane filter core, pH value detector, still includes pH value regulator, bypass solenoid valve, clean water bucket and PLC controller, set up two branches after the pH value detector, be equipped with pH value regulator on a branch road, another is equipped with the bypass solenoid valve on a branch road, two branches all with the clean water bucket intercommunication, wherein, water inlet and municipal tap water intercommunication, clean water bucket and play tap intercommunication.

Preferably, a concentrated water outlet is arranged behind the reverse osmosis or nanofiltration membrane filter element.

Preferably, the PLC controller is respectively and electrically connected with the water inlet electromagnetic valve, the booster pump, the pH value detector, the pH value regulator and the bypass electromagnetic valve.

The utility model has the advantages that: the utility model is provided with the pH value detector behind the reverse osmosis or nanofiltration membrane filter element, and by setting the range of the pH value detector, when the pH value of the direct drinking water is measured to be lower, the bypass electromagnetic valve is automatically closed, the pH value regulator is opened, the water is mineralized to reach alkalescence and increase the taste; when the direct drinking water is in the set range, the pH value regulator is closed, the bypass electromagnetic valve is opened, and the bypass water is discharged and directly enters the water tank. The method improves the taste of the discharged water and improves the quality of the direct drinking water.

Detailed Description

Example 1

The embodiment provides a household water purifier capable of automatically adjusting outlet taste, which is characterized by comprising a water inlet 1, a water inlet electromagnetic valve 2, a PP cotton filter element 3, a granular activated carbon filter element 4, a compressed activated carbon filter element 5, a booster pump 6, a reverse osmosis or nanofiltration membrane filter element 7 and a pH value detector 9 which are sequentially communicated, and further comprising a pH value adjuster 10, a bypass electromagnetic valve 11, a water purifying barrel 12 and a PLC (programmable logic controller) 14, wherein two branches are arranged behind the pH value detector 9, one branch is provided with the pH value adjuster 10, the other branch is provided with the bypass electromagnetic valve 11, and the two branches are both communicated with the water purifying barrel 12, wherein the water inlet 1 is communicated with municipal tap water, and the water purifying barrel 12 is communicated with an outlet tap 13; a concentrated water discharge outlet 8 is arranged behind the reverse osmosis or nanofiltration membrane filter element 7; the PLC 14 is respectively electrically connected with the water inlet electromagnetic valve 2, the booster pump 6, the pH value detector 9, the pH value regulator 10 and the bypass electromagnetic valve 11.

The more detailed explanation is:

the utility model provides a when family expenses water purifier begins to make water, municipal running water flows through the cotton filter core of PP 3, granule active carbon filter core 4, compressed active carbon filter core 5 in proper order from water inlet 1 through inlet solenoid valve 2, and the water after the prefiltering gets into reverse osmosis or receives filter membrane filter core 7 and carries out the depth filtration after the 6 pressure boost of booster pump, and harmful substance such as the bacterium of aquatic, virus, heavy metal and organic matter all are got rid of, and the play water is straight drinking water. The direct drinking water flows through the pH value detector 9, and by setting the range of the pH value detector 9, when the pH value of the direct drinking water is detected to be lower, the pH value detector 9 transmits data to the PLC 14, the PLC controls the bypass electromagnetic valve 11 to be automatically closed, the pH value regulator 10 is opened, the water is mineralized to achieve alkalescence, and the taste is improved; when the direct drinking water is in the set range, the pH value regulator 10 is closed, the bypass electromagnetic valve 11 is opened, the bypass water flows out and directly enters the purified water bucket 12, the purpose of improving the taste of the water is achieved, and the quality of the direct drinking water is improved.
