[0002] In order to improve the quality of life and obtain clean and usable domestic water, many water purification systems have been developed on the market.

[0003] The water purification system is used to connect the water supply network and then branch out several branch pipelines, according to the requirements and working conditions of each branch pipeline, different types and different levels of water purification equipment are installed, and multiple water purification equipment can be combined for use according to the requirements of special working conditions. However, some branch pipelines do not need to be filtered because their water requirements are low, and some branch pipelines also have different requirements for filtration according to different stages. According to the above problems, the present application is born. SUMMARY

[0004] The purpose of the present application is to provide a water purification system which can adjust the position of the water purification equipment according to the different requirements of the branch pipeline, so as to reduce the amount of water purification equipment, lower the cost and improve the water purification effect.

[0005] The above technical purpose of the present application is realized by the following technical scheme: a water purification system comprising a water supply network and a plurality of branch pipelines, the water supply network is connected with the plurality of branch pipelines through a docking pipe box, the docking pipe box is in communication with the plurality of branch pipelines, a filtering mechanism is arranged in the docking pipe box, a first driving assembly is arranged on the docking pipe box to drive the filtering mechanism to switch between the plurality of branch pipelines, when the filtering mechanism corresponds to one of the branch pipelines, the fluid medium entering the branch pipeline is filtered.

[0006] By adopting the above technical scheme, the position of the filtering mechanism is adjusted by the first driving assembly according to the requirements of the working conditions connected by the branch pipeline, when the filtering mechanism is adjusted to correspond to one of the branch pipelines, the fluid medium flowing into the branch pipeline is filtered by the filtering mechanism, so as to reduce the amount of water purification equipment, lower the cost and improve the water purification effect, and better adapt to different working condition requirements. And this kind of structure also realizes the complete installation of the pipeline, and then selects the filtering according to the demand of the pipeline layout, so as to avoid the installation error caused by the pre-installation of the water purification equipment and the layout of the pipeline, and make the installation and layout of the water purification system more convenient.

[0007] Further, the filtering mechanism comprises a mounting frame, a filtering barrel movably arranged in the mounting frame and having an opening, and a control assembly cooperating with the fluid medium to control movement of the filtering barrel, the opening of the filtering barrel is opposite to the flow direction of the fluid medium, and the filtering barrel is arranged in the mounting frame to reciprocally slide along the flow direction of the fluid medium, the control assembly cooperates with the fluid medium to control the filtering barrel to have a filtering state and a moving state for switching the filtering barrel between the branch pipelines, and a sealing assembly is arranged between the filtering barrel and the branch pipelines to form a seal when the filtering barrel is in the filtering state.

[0008] By using the above technical scheme, the control assembly cooperates with the fluid medium to control movement of the filtering barrel and switches the filtering barrel between the filtering state and the moving state, so that the filtering barrel in the filtering state can achieve better filtering efficiency on the fluid medium, and the moving switching function of the filtering barrel in the later stage will not be interfered in structure, and the sealing assembly is further arranged to reduce the probability of the fluid medium entering the branch pipeline without being filtered, thereby ensuring the filtering quality of the filtering mechanism.

[0009] Further, the control assembly comprises a water hammer plate arranged in the filtering barrel and moving therewith, a flow gap formed between the water hammer plate and the filtering barrel, and a plurality of return springs connecting the mounting frame and the filtering barrel.

[0010] By using the above technical scheme, the filtering barrel moves to a position corresponding to one of the branch pipelines under the action of the first driving assembly, the fluid medium flows and impacts on the water hammer plate and then drives the filtering barrel into the branch pipeline, and the fluid medium flows towards the branch pipeline after passing through the filtering barrel and the flow gap, so that the fluid medium can be better filtered and the probability of the fluid medium entering the branch pipeline without being filtered can be further reduced, thereby improving the filtering quality. When the position of the filtering barrel needs to be switched, the water inlet of the water supply network is cut off, the filtering barrel loses the impact force of the fluid medium and is reset under the action of the return spring, thereby ensuring the position switching function of the filtering barrel.

[0013] Further, the sealing assembly comprises a sealing ring fixedly arranged on the outer circumferential wall of the filter barrel and abutting against the blocking ring, and a sealing ring arranged between the sealing ring and the blocking ring.

[0014] By adopting the above technical scheme, the sealing ring abuts against the blocking ring when the filter barrel enters the branch pipeline, thereby forming a seal between the filter barrel and the branch pipeline, preventing the fluid medium from entering the branch pipeline without being filtered, and improving the filtering quality.

[0015] Further, the docking pipe box is formed with a guide rod, the mounting frame is in sliding cooperation with the guide rod, and the first driving assembly comprises a screw rod sealingly and rotatably arranged in the docking pipe box and threadedly connected with the mounting frame, and a first motor arranged outside the docking pipe box and used for driving the screw rod to rotate.

[0017] Further, the docking pipe box is formed with a cleaning cavity at one end of the movement path of the mounting frame, a partition plate is arranged at the bottom position between the cleaning cavity and the inner cavity of the docking pipe box, a drain port is arranged on the docking pipe box and communicates the cleaning cavity with the outside, a cover is threadedly connected on the drain port, a high-pressure cleaning nozzle is movably arranged in the cleaning cavity, and a second control member is arranged outside the docking pipe box and used for controlling the high-pressure cleaning nozzle to enter or exit the filter barrel.

[0018] By adopting the above technical scheme, when the impurities in the filter barrel need to be cleaned, the filter barrel is controlled by the first driving assembly to enter the cleaning cavity, then the water inlet of the water supply network is cut off, and the high-pressure cleaning nozzle is driven by the second control member to enter the filter barrel for cleaning, the sewage generated in the cleaning process is discharged through the drain port, and the sewage is prevented from entering the inner cavity of the docking pipe box by the partition plate, thereby avoiding secondary pollution.

[0019] Further, the second control member comprises a water inlet pipe extending into the cleaning cavity through the docking pipe box, a second motor connected with the water inlet pipe and used for controlling the rotation of the water inlet pipe, and a pneumatic cylinder used for driving the second motor to move, the water inlet pipe is connected with the high-pressure cleaning nozzle and sealingly and movably cooperates with the docking pipe box.

[0020] By adopting the above technical scheme, the pneumatic cylinder controls the second motor to drive the high-pressure cleaning nozzle to enter the inside of the filter barrel, and then the second motor drives the high-pressure cleaning nozzle to rotate, so that the inner wall of the filter barrel is uniformly cleaned, thereby ensuring the cleaning quality.

[0021] Further, the high-pressure cleaning nozzle comprises a side wall cleaning section used for cleaning the inner circumferential wall of the filter barrel, and a cleaning head connected with the side wall cleaning section and used for cleaning the bottom of the filter barrel.

[0022] By adopting the above technical solution, the cleaning head, together with the side wall cleaning section, covers the inner circumferential wall of the filter barrel as the second motor rotates, achieving all-round uniform cleaning.

[0023] A further setting is made: a water purifier is installed on a portion of one of the branch pipes.

[0024] By adopting the above technical solutions, the water purifier, in conjunction with the filtration mechanism, can adapt to the filtration levels required for different operating conditions.
