Description

Technical Field

[0001] The utility model relates to water purification technology, in particular to an intelligent antibacterial portable water purification system with recyclable backwashing and a water purifier thereof. Background Art

[0002] Existing outdoor water purifiers cannot meet the long-term and effective filtration of natural source water. Because there are many impurities in the water source under natural conditions, the existing water purifiers are prone to block the filter element after filtration. Existing filter elements such as PP cotton rods, carbon rods, RO reverse osmosis membranes, etc. cannot be disassembled and cleaned. After the filter element is blocked, only the filter element can be replaced, which seriously affects the service life and cycle of the filter element. In addition, there is an ultrafiltration membrane that can be manually cleaned, but this ultrafiltration membrane needs to be used continuously. Once it is used and then left idle for a period of time and then used again, this ultrafiltration membrane will fail and will not filter water.

[0003] In addition, for existing water purifiers, their water purification systems include pipelines. A pre-filter is installed at the front end of the pipeline, and a filter element assembly and a power assembly (including a water pump) are installed on the pipeline. During use, a water purification bucket is placed at the end of the pipeline and connected to the end of the pipeline. Then, the front end of the pipeline together with the pre-filter is placed in the water source, and the power assembly (including the water pump) is started to pump water. The water is filtered by the pre-filter and the filter element assembly and then stored in the water purification bucket; The pipeline has drained the water stored in the filter element assembly and part of the pipeline, but the filter element assembly and part of the pipeline are still in a relatively humid environment, and there is still a risk of secondary pollution. After the water stored in the filter element assembly is discharged by the pre-filter, air is continuously passed through. The air is discharged by the pre-filter to discharge the humid air, dry the inside of the filter element assembly and the pipeline, and at the same time perform a secondary backwash on the pre-filter to clean the pre-filter; of course, at this time, the pre-filter is removed from the water source. Figure 1 After the filtration is completed, there is stored water inside the filter element. In the case of short-term or long-term non-use of the water purifier, this stored water will instead produce bacteria and cause secondary pollution; the stored water in the filter element and pipeline inside the device will freeze in a state of extremely low temperature, causing problems such as freezing and cracking of the device and pipeline. Summary of the Utility Model

[0004] To overcome the above technical defects, the utility model provides an intelligent antibacterial portable water purification system with recyclable backwashing and a water purifier thereof, aiming to solve the problems in the above background art that the pre-filter element is prone to blockage and has a short service life, and the stored water in the filter element assembly and pipeline will cause secondary pollution and freeze and cause damage in a low-temperature environment.

[0005] The technical solution of the utility model is as follows:

[0006] An intelligent antibacterial portable water purification system with recyclable backwashing, the water purification system includes a pipeline, a pre-filter element, a water purification bucket, a filter element assembly, and a pumping assembly.

[0007] A branch pipe connects pipeline I and pipeline II. A valve I is installed on pipeline I, and valve I is located downstream of the connection between the branch pipe and pipeline I. A valve II is installed on pipeline II, and valve II is located downstream of the connection between the branch pipe and pipeline II. A valve III is installed on the branch pipe;

Use the stored water (clean water) in the filter element assembly and part of the pipeline to backwash the pre-filter element, killing two birds with one stone. That is, the stored water in the filter element assembly and the pipeline is discharged, avoiding the problem of secondary pollution caused by the stored water and damage caused by freezing expansion at low temperatures from the source, and at the same time cleaning the pre-filter element to prevent its blockage and extend its service life.

[0009] For further optimization of the above technical solution, an air inlet is provided on pipeline Ⅰ. The air inlet is located downstream of valve Ⅰ, and valve Ⅳ is installed thereon.

[0011] For further refinement of the above technical solution, as Figure 2 Figure 3 Figure 4 Figure 5 Figure 6

[0012] There is still stored water in the remaining pipeline. For further optimization of the above technical solution, after the stored water in the filter element assembly and part of the pipeline is discharged from the pre-filter element, valve Ⅰ remains closed, valve Ⅲ remains closed, valve Ⅳ remains open, close valve Ⅱ, and air enters from the air inlet to send the stored water in the remaining pipeline into the water purification bucket; of course, after the water purification bucket is removed, continuously pass air to dry the remaining pipeline.

[0013] For further optimization of the above technical solution, the one-two position three-way valve is installed at the connection of the branch pipe and pipeline Ⅱ, that is, valve Ⅱ and valve Ⅲ; the one-two position three-way valve is installed on pipeline Ⅰ, upstream of the connection of the branch pipe and pipeline Ⅰ, that is, valve Ⅱ and valve Ⅳ, and one of its inlets is the air inlet; reducing the number of valves used makes the structure more compact.

[0014] For further optimization of the above technical solution, the pumping assembly includes several water pumps; pumping is convenient and efficient.

[0015] For further optimization of the above technical solution, a flow meter, UV sterilization, and TDS water quality detection are also installed on the pipeline; for sterilization, and real-time monitoring of the flow and water quality.

[0016] For further refinement of the above technical solution, the two-position three-way valve is an electromagnetic valve; the water purification system further includes a control system, and the control system is connected to the two two-position three-way valves and the pumping assembly; realizing the automatic control of the water purification system.

[0017] The control system is a single-chip microcomputer control system.
