A water purifier with intelligent water-saving function

Abstract

The invention discloses a water purifier with an intelligent water-saving function. The water purifier comprises a water purifier body internally provided with a water storage container, wherein a water inlet and a water outlet are formed in the water purifier body, a reverse osmosis filter is arranged inside the water purifier body, a water inlet pipe is connected between the reverse osmosis filter and the water inlet, a water outlet pipe is connected between the reverse osmosis filter and the water outlet, a water inlet valve is arranged on the water inlet pipe, the water storage container is connected with the water outlet pipe, a concentrated water discharge pipe is arranged on the reverse osmosis filter, a discharge valve is arranged on the concentrated water discharge pipe, a backflow branch is arranged between the concentrated water discharge pipe and the water inlet pipe, a backflow valve is arranged on the backflow branch, the water purifier body is also internally provided with a main control chip, the main control chip is connected with a TDS sensor which is arranged at the outlet end of the backflow branch and the main control chip is in control connection with the water inlet valve, the discharge valve and the backflow valve. The water purifier has the advantages that the structure is simple, the water purifier is convenient to use, the concentrated water can be recycled and the discharge of the concentrated water can be automatically controlled.

Description

technical field [0001] The invention relates to the field of water purifier manufacturing, in particular to a water purifier with an intelligent water-saving function. Background technique [0002] Water dispensers have become widely used drinking water equipment in homes, offices and public places. In the past, water dispensers mostly used bottled water as raw water. When the water consumption was relatively large in summer, the normal use of the water dispenser was often affected because the water delivery workers were too busy to deliver water in time. With the continuous advancement of water dispenser technology, water purifiers have gradually replaced water dispensers that use bottled water. The water purifier is directly connected to municipal water, and the impurities and peculiar smell in the water are removed through its internal water purification device to meet the drinking standard. It is very convenient to use and low in use cost. [0003] Since the developmen...

Problems solved by technology

[0005] Concentrated water is not drinkable, and it is often discharged directly. The discharge of this part of the concentrated water will cause a lot of waste of water resources; and the concentrated water produced in different regions is different due to the difference in water quality, so the concentrated water discharge ratio needs to be adjusted. Therefore, the structure of the existing reverse osmosis membrane water purifier needs to be further improved
