Referring to fig. 1 to 8, the present embodiment provides an RO filter element with a water stop structure, which includes a filter element body 1, a water stop component, and a filter element seat, wherein a water purifying pipe 11 and an RO membrane coated on the periphery of the water purifying pipe 11 are coaxially disposed in the filter element body 1; the water stopping component is configured at the head of the filter element body 1 and comprises a movable piece 21 and a fixed piece 22 sleeved outside the movable piece 21, wherein the fixed piece 22 is in limit connection with the filter element body 1 through a clamping ring 221, the movable piece 21 is communicated with the water purifying pipe 11 to form a pure water outlet waterway, a raw water inlet waterway is formed between the fixed piece 22 and the inner wall of the filter element body 1, and a waste water outlet waterway is formed between the fixed piece 22 and the movable piece 21; the filter element seat comprises a water inlet piece 313, a rotating piece 32 and a connecting piece 33, wherein the connecting piece 33 is connected with the filter element body 1 in an adapting way, the water inlet piece 313 is clamped and fixed with the connecting piece 33, the rotating piece 32 is configured between the water inlet piece 313 and the connecting piece 33 to rotate, and a limiting part for limiting the rotation angle of the rotating piece 32 is arranged on the connecting piece 33; specifically, the water inlet member 313 is provided with a raw water inlet 311, a waste water outlet 312 and a pure water outlet 313 corresponding to a raw water inlet waterway, a waste water outlet waterway and a pure water outlet waterway, the rotary member 32 is provided with water passing holes corresponding to the inlets and outlets on the water inlet member 313 one by one, and the rotary member 32 is driven to rotate in an operable manner, so that the water passing holes are conducted with the inlets and outlets on the water inlet member 313 relatively or are sealed relatively. The sealing structure between the water inlet 313 and the rotary member 32 may be, but not limited to, a sealing structure by the gasket 34, or a sealing structure between the water inlet 313 and the rotary member 32 by a sufficiently smooth surface.
In this embodiment, the water is stopped by arranging the rotating member 32 at the head of the filter element body 1, so as to avoid the problem that other water functions cannot be used normally due to the water source being closed when the filter element is replaced, and meanwhile, the machine (such as a water purifier) can be prevented from being broken down due to the fact that water flows leak to the inside of the machine. In addition, with stagnant water structure setting at the head of filter core body 1 to promoted the space utilization of filter core body 1, increased the usable floor area of RO membrane, thereby realized the large-traffic play water more than 1000G.
Based on the above embodiment, in an alternative embodiment of the present utility model, the fixing member 22 is sleeved with the water stop gasket 222 for controlling the on-off of the raw water inlet waterway, when the raw water inlet 311 is in alignment connection with the water passing hole, the water stop gasket 222 is bent downwards under the upper water flow pressure to enable the water to pass through, and when the raw water inlet 311 is misplaced with the water passing hole, the water stop gasket 222 is abutted upwards under the water flow pressure inside the filter element body 1 to seal, so that the raw water inlet waterway is disconnected. Further, the water purifying pipe 11 is sleeved with a connecting pipe 12, the connecting pipe 12 is connected with the fixing piece 22 through threads, the connecting pipe 12 is communicated with a through hole communicated with the water purifying pipe 11 and the movable piece 21, and a one-way valve 23 used for controlling the on-off of a water way of pure water outlet is arranged between the connecting pipe 12 and the movable piece 21 in a propping way, so that the water flow direction is from the water purifying pipe 11 to the pure water outlet 313, and the water backflow pollution of the pure water in the water purifying pipe 11 is avoided. Preferably, one end of the movable member 21 is matched with the rotating member 32, an elastic member 211 is abutted between the other end and the connecting pipe 12, a sealing member 212 is sleeved on the movable member 21, and the sealing member 212 is configured to move downwards or upwards through the rotating member 32 so as to control the on-off of a water path of wastewater outlet. For example, when the water passing hole of the rotating member 32 rotates to be in alignment conduction with the waste water outlet 312, the driving structure on the rotating member 32 presses down the movable member 21 to drive the movable member 21 to move downward, so that the waste water outlet waterway is conducted; or when the water passing hole of the rotating member 32 rotates to be sealed with the waste water outlet 312 in a dislocation way, the driving structure on the rotating member 32 releases the movable member 21, and at the moment, the movable member 21 moves upwards under the action of the elastic member 211, so that the sealing member 212 arranged on the movable member 21 abuts against the fixed member 22 to seal, and correspondingly, the waste water outlet waterway is disconnected. The driving structure on the rotating member 32 may be an inclined plane inclined downward from top to bottom around the inner wall of the rotating member 32, when the water passing hole of the rotating member 32 rotates to be communicated with each inlet and outlet, the movable member 21 abuts against the bottom of the inclined plane, and when the water passing hole of the rotating member 32 rotates to be misplaced with each inlet and outlet, the movable member 21 abuts against the top of the inclined plane under the action of the elastic member 211, which is not limited thereto.
It should be noted that, in this embodiment, the filter element body 1 is isolated from the external water flow by the rotating member 32, and the raw water inlet waterway, the waste water outlet waterway and the pure water outlet waterway are synchronously disconnected by the water stopping assembly, so that the dual water stopping is realized. It will be readily appreciated that the water stop of the cartridge body 1 can be achieved by merely rotating the cartridge body 1 to drive the rotary member 32 to the blocking position. When the filter element is replaced, a water source is not required to be closed, so that other water use activities can be normally performed. In addition, set up the stagnant water structure at the top of filter core body 1 and can carry out the core operation of trading under the condition of not demolishing external connection hose, can avoid the hose damage when saving assembly time.
The above is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model.
