Description

Technical Field

[0001] This application relates to the technical field of water purification devices, and in particular to a high-flow-rate suspended ultrafiltration forward and reverse flushing device. Background Technology

[0002] Water purifiers, also known as water filters or water purifiers, are water treatment devices that perform deep filtration and purification of water according to the requirements for water use.

[0003] Currently, water purifiers include an outer shell, a central tube fixedly connected inside the outer shell, and a filter element fixedly connected to the central tube. The outer shell includes a top cover and a lower shell connected to the top cover. According to Chinese patent CN 203809772U, the top cover is equipped with a fork, a fixed valve, a movable valve plate, a first through hole, a second through hole, a third through hole, a fourth through hole, a fifth through hole, a sixth through hole, a blind guide hole, a water flow through hole, a brine control valve, an inlet, an outlet, and a drain outlet. It is also equipped with a brine cleaning device, which is connected to the brine control valve. Then, by adjusting the upper and lower water distributors, the water flow direction inside the water purifier is adjusted. When the user needs purified water, by rotating the fork, when the through hole on the movable valve plate coincides and connects with the second through hole on the fixed valve plate, the blind guide hole connects the third and fourth through holes. The blind guide hole only connects with the sixth through hole, and the brine control valve is closed. At this time, the water entering from the inlet flows through the through-hole into the second through-hole, through the valve body to the upper part of the filter element, through the upper water distributor into the lower housing, and after being processed by the filter element, it flows through the lower water distributor to the lower part of the filter element, flows to the third through-hole, and after being guided by the guide blind hole, flows to the fourth through-hole. Since the fourth through-hole is connected to the outlet, the water flows out from the outlet, achieving the purpose of water purification. When the user needs to clean the water purifier, close the brine control valve, and by rotating the lever, when the first through-hole on the moving valve plate coincides and connects with the third through-hole on the fixed valve plate, the guide blind hole connects the first through-hole and the sixth through-hole, and the guide blind hole only connects with the fourth through-hole, thus closing the brine control valve. At this time, the water flowing in from the inlet enters the third through hole through the through hole, passes through the valve body to the lower part of the filter element, enters the water treatment tank through the lower water distributor, flows upward through the filter element, loosens and washes the filter element, and the washed-off dirt flows through the upper water distributor to the upper interface of the filter element, flows to the first through hole, and flows to the sixth through hole after being guided by the blind hole. Since the sixth through hole is connected to the drain outlet, the water flows out from the drain outlet, thus achieving cleaning.

[0004] When replacing the internal filter cartridges of a water purifier, the inventor discovered that disassembling the water purifier requires using a specific wrench to open the pipes and the outer casing before the internal filter cartridges can be disassembled and replaced. This makes the replacement of the filter cartridges very troublesome and the cleaning efficiency very low. Utility Model Content
