The ultrafiltration membrane module 30 is communicated with the water inlet pump 10 and used for filtering sewage introduced from the water inlet pump 10, the ultrafiltration membrane module 30 comprises a shell, an ultrafiltration membrane and the like, the filtration precision of the ultrafiltration membrane is 0.01 micron, and microorganisms, colloid, diatom and other substances causing turbidity can be removed. The ultrafiltration membrane has good hydrophilicity, long service life and strong anti-pollution capability, can retain beneficial minerals and can be used for kitchen water purifiers, and the ultrafiltration membrane component 30 has large water yield but filtered water cannot be directly used.
The reverse osmosis membrane module 40 is communicated with the water inlet pump 10, and is used for filtering sewage introduced from the water inlet pump 10, and includes a housing, a reverse osmosis membrane, and the like. The reverse osmosis membrane has the filtering precision of 0.0001 micron (one-ten-thousandth micron), is a filter element with extremely high filtering precision at present, and can filter bacteria, heavy metals, organic matters, residual chlorine, colloid substances and other harmful substances in water. The water filtered by the reverse osmosis membrane can be directly used, but the water yield is low.
The water storage module 50 is communicated with the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 and is used for storing water filtered by the ultrafiltration membrane module 30 and/or the reverse osmosis membrane module 40.
The water storage assembly 50 comprises a domestic water tank 51 and a direct drinking water tank 52, wherein the domestic water tank 51 is communicated with the ultrafiltration membrane assembly 30 and is used for receiving water filtered by the ultrafiltration membrane assembly 30; the direct drinking water tank 52 is communicated with the reverse osmosis membrane module 40 and is used for receiving water filtered by the reverse osmosis membrane module 40, so that water filtered by the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 is separated and stored, confusion of two types of filtered water is avoided, and different filtering modules can be conveniently opened in different application scenes. The switching component 60 is connected with the ultrafiltration membrane component 30 and the reverse osmosis membrane component 40, and is used for switching water entering from the water inlet pump 10 to be filtered through the ultrafiltration membrane component 30 and/or the reverse osmosis membrane component 40, that is, through the switching component 60, the ultrafiltration membrane component 30 can be controlled alone to filter sewage, the reverse osmosis membrane component 40 can be controlled alone to filter sewage, and the ultrafiltration membrane component 30 and the reverse osmosis membrane component 40 can be controlled together to filter sewage.
Based on the above embodiment, the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 are both communicated with the water inlet pump 10; the domestic water tank 51 is communicated with the ultrafiltration membrane module 30 and is used for receiving water filtered by the ultrafiltration membrane module 30, and the direct drinking water tank 52 is communicated with the reverse osmosis membrane module 40 and is used for receiving water filtered by the reverse osmosis membrane module 40; the switching module 60 is connected with the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 and is used for switching the sewage entering from the water inlet pump 10 to be filtered by the ultrafiltration membrane module 30 and/or the reverse osmosis membrane module 40. When the domestic water is used, the advantage of large water yield of the ultrafiltration membrane component 30 is utilized, and the sewage entering the water inlet pump is rapidly filtered through the ultrafiltration membrane component 30 alone, so that the requirement of a large amount of domestic water in time is met.
In some embodiments, the shift assembly 60 includes a filter housing 61, a first drive member 62, and a second drive member 63. The filter shell 61 is provided with a filter cavity 61a, the filter cavity 61a is communicated with the water inlet pump 10, the domestic water tank 51 and the direct drinking water tank 52, and the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 are arranged in the filter cavity 61a, so that the sewage enters the filter cavity 61a from the water inlet pump 10, is filtered by the ultrafiltration membrane module 30 and/or the reverse osmosis membrane module 40, and can be discharged into the water storage module 50 for storage. First driving piece 62 sets up in filtering shell 61 inner wall, and first driving piece 62 is connected with milipore filter subassembly 30 for drive milipore filter subassembly 30 switches between operating position and inoperative position, and at operating position, milipore filter subassembly 30 filters sewage, and at the inoperative position, sewage does not pass through milipore filter subassembly 30, and milipore filter subassembly 30 does not filter sewage. The second driving member 63 is disposed on the inner wall of the filtering shell 61, and the second driving member 63 is connected to the reverse osmosis membrane module 40 and is configured to drive the reverse osmosis membrane module 40 to switch between an operating position and a non-operating position, in the same way, in the operating position, the reverse osmosis membrane module 40 filters the sewage, in the non-operating position, the sewage does not pass through the reverse osmosis membrane module 40, and the reverse osmosis membrane module 40 does not filter the sewage. When the ultrafiltration membrane module 30 and the reverse osmosis membrane module 40 are both in working positions, the ultrafiltration membrane module 30 is used for primary filtration of sewage, and the reverse osmosis membrane module 40 is used for secondary filtration of sewage, so that the service life of the reverse osmosis membrane module 40 can be prolonged, and the cost of the reverse osmosis membrane module 40 is higher than that of the ultrafiltration membrane module 30, so that the filtration cost can be reduced. It can be understood that under the scene of large water consumption such as a kitchen, the sewage can be filtered only through the ultrafiltration membrane module 30, so that the requirement of large water consumption of the kitchen is met; in a scene where the water consumption is small, such as when drinking water is provided to a user, sewage can be filtered only through the reverse osmosis membrane module 40, so that a demand that the sewage can be directly drunk after being filtered is met, and thus, applicable scenes of the sewage filtering apparatus 100 capable of switching the filtering modules can be increased.
In some embodiments, a first water level sensor 511 is disposed in the domestic water tank 51, and when the first water level sensor 511 detects that the water level in the domestic water tank 51 drops to a preset first low water level, the ultrafiltration membrane module 30 can be rotated to the working position alone to perform filtration treatment on sewage and store the filtered water in the domestic water tank 51; the second water level sensor 512 is arranged in the direct drinking water tank 52, and when the second water level sensor 512 detects that the water level in the direct drinking water tank 52 is lowered to a preset second low water level, at least the reverse osmosis membrane module 40 can be rotated to a working position to filter sewage and store the filtered water in the direct drinking water tank 52. Domestic water is filtered through milipore filter subassembly 30 alone, and not only the water yield is big, can satisfy a large amount of and timely demands of domestic water, and directly drink water and do not do domestic water, directly drink water demand reduction, can prolong the life of reverse osmosis membrane subassembly 40, reduce cost.

When the second water level sensor 521 detects that the water level in the straight drinking water tank 52 drops to the second low water level, the three-way valve 90 controls the filter chamber 61a to communicate with the straight drinking water tank 52, so that the water filtered by the reverse osmosis membrane module 40 is stored in the straight drinking water tank 52.
The sewage filtering apparatus 100 with switchable filtering assemblies further comprises a third water level sensor 522, the third water level sensor 522 is disposed in the direct drinking water tank 52 and is located at a position lower than the second water level sensor 521, when the first water level sensor 511 detects that the water level in the domestic water tank 51 drops to the first low water level, and at the same time, the second water level sensor 521 detects that the water level in the direct drinking water tank 52 drops to the second low water level, and when the third water level sensor 522 detects that the water level in the direct drinking water tank 52 drops to a preset third low water level from the second low water level within a preset time, it indicates that the user needs to use direct drinking water, at this time, the reverse osmosis membrane assembly 40 can be rotated to a working position to filter sewage, and the three-way valve 90 controls the filtering cavity 61a to communicate with the direct drinking water tank 52, so as to store filtered water into the direct drinking water tank 52 and use the filtered water for the user, thereby satisfying the immediate demand of the direct drinking water user.
