Filter system of water purifying plant and water purifying plant with same

Abstract

The invention discloses a filter system of a water purifying plant and the water purifying plant with the same. The filter system comprises a prepositioned filter element, a booster pump, an RO membrane filter element, a flexible water bag, a post-positioned filter element and an UV lamp, wherein the prepositioned filter element is connected with an outer water source to preliminarily purify the water quality; the booster pump is connected to the downstream of the prepositioned filter element through an inlet water magnetic valve; the RO membrane filter element is connected with the downstream of the booster pump and is provided with a water inlet, a purified water outlet and a wastewater outlet; the flexible water bag is connected with the purified water outlet of the RO membrane filter element; the post-positioned filter element is connected with the flexible water bag through a water pump so as to further purify water from the flexible water bag, and is applicable to being connected with a water faucet; and the UV lamp is used for sterilizing water in the flexible water bag. According to the filter system of the water purifying plant dislcosed by the embodiment of the invention, the UV lamp can be used for sterilizing the water in the flexible water bag once again, and the flexible water bag is prevented from bacteria breeding during long-term suspension, thus further improving the water quality of drinking water and ensuring health drinking water for users.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a filter system of the water purification equipment and the water purification equipment provided with it. Background technique [0002] With the vigorous development of the water purification equipment market, more and more water purification equipment have entered thousands of households. At present, the mainstream of water purification equipment is RO reverse osmosis water purifier, and RO reverse osmosis water purifier is divided into large flow and small flow. There are two types. The large flow mainly includes 400 gallons, 500 gallons, 600 gallons, etc. The small flow mainly includes 50 gallons, 75 gallons, 100 gallons and 200 gallons. Consumers need it, but the price is expensive, and it is difficult for ordinary families to accept it. The small flow system usually produces about 0.2-0.5L of water per minute, and it usually takes 1-2 minutes to receive...

[0002] With the vigorous development of the water purification equipment market, more and more water purification equipment have entered thousands of households. At present, the mainstream of water purification equipment is RO reverse osmosis water purifier, and RO reverse osmosis water purifier is divided into large flow and small flow. There are two types. The large flow mainly includes 400 gallons, 500 gallons, 600 gallons, etc. The small flow mainly includes 50 gallons, 75 gallons, 100 gallons and 200 gallons. Consumers need it, but the price is expensive, and it is difficult for ordinary families to accept it. The small flow system usually produces about 0.2-0.5L of water per minute, and it usually takes 1-2 minutes to receive a glass of water. Therefore, traditional small flow systems are usually equipped with 3 to The 5-gallon pressure tank stores water to increase the net water flux at the end and shorten the waiting time for water intake. There are several disadvantages in this way of storing water in the pressure tank and pressurizing the water outlet: First, the water storage tank is too large to completely drain the water Clean, some water will remain every time, resulting in stagnant water quality and easy breeding of bacteria. Second, the pressure tank is relatively large and can only be installed externally, taking up space, and the waterway is complicated
