Purifier for reverse osmosis direct drinking machine

Abstract

The invention relates to a water purification device for a reverse osmosis directly drinkable water dispenser. The device comprises a water tank divided into a raw water chamber and a waste water chamber, a primary filtering device, a reverse osmosis treatment device and a clean water tank, and is characterized in that the primary filtering device and the reverse osmosis treatment device are arranged in a shell. The shell has two water openings. The bottom of the shell has a general water outlet which is connected with the clean water tank. The water tank is arranged above the shell detachably. Elastic internal pressure self-sealing valves are arranged at a raw water outlet and a waste water recovery opening of the water tank. In the water purification device, the water tank does not need to be connected with a water pipe and to be arranged in a place wherein water pipes are arranged, so the directly drinkable water dispenser using the water purification device suffers no limit on installation place and can be arranged at any place. The water purification device is convenient in use, particularly suitable for domestic application. And a waste water outlet is not required to be arranged on the water tank, and a special concentrated water discharge pipeline is not required, so the water purification device is simpler in structure, more reasonable in arrangement and the same with the prior drinkable water dispenser in terms of use occasion and mode.

Description

technical field [0001] The invention relates to a water purification device, in particular to a water purification device for a reverse osmosis direct drinking water machine. Background technique [0002] With the strengthening of people's awareness of drinking water safety, people's requirements for drinking water quality are getting higher and higher. Bottled water of various qualities continues to appear, and drinking water dispensers are widely used thereupon. The water dispenser must use bottled water produced by the manufacturer, and the tap water cannot be filtered, and the drinking cost is relatively high. Aiming at the aforementioned present situation, a kind of direct drinking water dispenser which directly filters tap water and then drinks is invented. [0003] The direct drinking water machine is mainly composed of a water purification device and a heating part (equivalent to an ordinary water dispenser). The water purification device is arranged on the upper pa...

AI Technical Summary

Problems solved by technology

[0007] Throughout the existing various direct drinking water dispenser devices, they have such a commonality, that is, the water storage tank for storing raw water and the waste water tank for storing concentrated water (also called waste water) are fixed and cannot be moved, so the water inlet of the water storage tank must be directly connected to the water tank. It is connected to the tap water pipe, and the water inlet solenoid valve is installed on the water pipe, while the waste water tank must be equipped with a waste water outlet and a drain solenoid valve at the waste water outlet, that is, the discharge of concentrated water requires a special pipe, and the structure is complex; Furthermore, the existing direct drinking water dispenser must be placed in a place where water pipes are arranged, and there is no water pipe arrangement in the living room or dining room of a general family. Direct drinking water dispensers cannot be placed in these places. However, the general household drinking water device is generally placed in the living room or dining room, and once the direct drinking water dispenser is placed, the place cannot be easily changed, so the existing direct drinking water dispenser has a limited range of placement and is inconvenient to use. It is more convenient to use the traditional water dispenser; when there is waste water to be discharged, a water container needs to be placed at the waste water outlet, and the drain solenoid valve is opened to discharge the waste water. At this time, the waste water is easy to overflow to the place where the direct drinking water machine is placed, and the discharge efficiency Low
