As shown in fig. 1, the multi-functional filter according to the embodiment of the first aspect of the present application includes a filter assembly 200, an outlet pipe 120, a soil exhaust pipe 130, an inlet pipe 110, a valve body 400, and a control assembly 500. Filter assembly 200 the filter assembly 200 includes a filter part partitioning the inside of the filter assembly 200 to form a raw water chamber 240 and a purified water chamber 250; the valve body 400 can switch the multifunctional filter to a filtering state, a backwashing state or a closing state; when the multifunctional filter is in a filtering state, the valve body 400 can enable the water outlet pipeline 120 to be communicated with the raw water cavity 240 and enable the water outlet pipeline 120 to be communicated with the purified water cavity 250; when the multifunctional filter is in a backwashing state, the valve body 400 enables the water outlet pipeline 120 to be communicated with the purified water cavity 250 and enables the sewage discharge pipeline 130 to be communicated with the raw water cavity 240; when the multifunctional filter is in a closed state, the valve body 400 closes the water inlet pipe 110, the water outlet pipe 120, the sewage discharge pipe 130, the purified water chamber 250, and the raw water chamber 240; and a control assembly 500 connected to the valve body 400 for controlling the valve body 400. The flow detection assembly 600 is disposed on the water inlet pipeline 110 or the water outlet pipeline 120, the flow detection assembly 600 is electrically connected to the control assembly 500, and the flow detection assembly 600 is configured to detect a water flow, determine whether the water pipeline of the user leaks water, and feed back a determination signal to the control assembly 500.

The filter part partitions the inside of the filter assembly 200 into two chambers, i.e., a raw water chamber 240 and a purified water chamber 250. The clean water chamber 250 is near the axial center of the filter assembly 200. The raw water chamber 240 is remote from the axial center of the filter assembly 200.

The valve body 400 is connected to the filter assembly 200, the water outlet line 120, the sewage line 130, and the water inlet line 110, respectively. The valve body 400 can control the water inlet pipeline 110 to be communicated or not communicated, can control the water inlet pipeline 110 to be communicated with the raw water cavity 240 or the purified water cavity 250, can control the sewage draining pipeline 130 to be communicated or not communicated with the raw water cavity 240, and can control the water outlet pipeline 120 to be communicated or not communicated with the purified water cavity 250.

When the multifunctional filter is in a normal filtering state, the valve body 400 controls the water inlet pipeline 110 to be communicated with the raw water cavity 240, the water outlet pipeline 120 to be communicated with the purified water cavity 250, and the sewage discharge pipeline 130 is not communicated. The tap water passes through the water inlet pipe 110, the valve body 400, the raw water chamber 240, the purified water chamber 250, the valve body 400, and the water outlet pipe 120 in sequence. And when the tap water passes through the filter part from the raw water chamber 240 to the purified water chamber 250, the tap water can be filtered through the filter part between the two chambers, and impurities will be deposited in the raw water chamber 240.

When the multifunctional filter is in a back flushing state, the valve body 400 controls the water inlet pipeline 110 to be communicated with the water purifying cavity 250, the sewage discharge pipeline 130 to be communicated with the raw water cavity 240, and the water outlet pipeline 120 not to be communicated. The tap water passes through the water inlet pipe 110, the valve body 400, the purified water chamber 250, the raw water chamber 240, the valve body 400, and the sewage draining pipe 130 in sequence. Because there is no separation between the raw water cavity 240 and the sewage discharge pipeline 130, impurities in the raw water cavity 240 can be carried away by tap water in a back-flushing state.

When the multifunctional filter is in a closed state, the valve body 400 controls the water inlet line 110 not to communicate with any one chamber. Tap water passes through the water inlet pipeline 110 and the valve body 400 in sequence, and the tap water is blocked by the valve body 400 and cannot continuously circulate.

The multifunctional filter according to the embodiment of the application has at least the following beneficial effects: the multifunctional filter has a filtering state and a back-flushing state, namely when the multifunctional filter is in the filtering state, the water inlet pipeline 110, the raw water cavity 240, the purified water cavity 250 and the water outlet pipeline 120 are communicated in sequence; when the multifunctional filter is in a back-flushing state, the water inlet pipeline 110, the purified water cavity 250, the raw water cavity 240 and the sewage discharge pipeline 130 are communicated in sequence. The multifunctional filter can be switched between a normal filtering state, a backwashing state and a closing state by only one valve body 400. The multifunctional filter has the advantages of simple structure, convenience in disassembly and assembly, small volume and small required installation space.

Meanwhile, the flow detection assembly 600 is disposed on the water inlet pipeline 110, and the flow detection assembly 600 can monitor the flow of water in the water inlet pipeline 110 in real time to determine whether the water leakage condition occurs in the water system of the user. When the flow detection assembly 600 judges that the water leakage condition exists, the flow detection assembly 600 feeds information back to the control assembly, the control assembly turns off the control valve body 400, the multifunctional filter is in a closed state, the circulation of a water pipeline for a user is blocked, and the damage caused by water leakage is prevented from further expansion. The multifunctional filter has the functions of monitoring water leakage of a water system for a user and timely cutting off protection, so that the multifunctional filter is multifunctional.

As shown in fig. 1 to 2, according to some embodiments of the present disclosure, the filter assembly 200 further includes a first housing 210, a filter part disposed inside the first housing 210, a purified water chamber 250 formed inside the filter part, and a raw water chamber 240 formed between the filter part and the first housing 210.

When the water inlet pipe 110 is connected to the raw water chamber 240, the water outlet pipe 120 can be connected to the purified water chamber 250, so that the tap water enters the purified water chamber 250 from the raw water chamber 240 and passes through the filter portion to achieve the filtering effect, and meanwhile, impurities in the tap water remain in the raw water chamber 240, i.e., the multifunctional filter is in a filtering state.

When the water inlet pipe 110 is communicated with the purified water chamber 250, the sewage draining pipe 130 can be communicated with the raw water chamber 240, so that tap water enters the raw water chamber 240 from the purified water chamber 250, and then the tap water carries away impurities in the raw water chamber 240 and is discharged from the sewage draining pipe 130, i.e. the multifunctional filter is in a back-flushing state.

When the water inlet line 110 is not connected to the raw water chamber 240 or the purified water chamber 250, i.e., the water inlet line 110 is closed by the valve body 400, the multifunctional filter is in a closed state.
