Description

Technical Field

[0001] This utility model relates to the technical field of water purification systems, and in particular to a water circuit system for improving the flow rate of an RO water purifier. Background Technology

[0002] The flow rate of a reverse osmosis water purifier is one of its important performance characteristics and a key concern for users. Water purifiers with higher flow rates offer a better user experience and are more popular with consumers.

[0003] Most high-flow reverse osmosis water purifiers on the market currently achieve this by using high-flow reverse osmosis membranes and high-flow booster pumps. Existing methods for increasing the flow rate of reverse osmosis water purifiers include:

[0004] 1: A single reverse osmosis membrane achieves a larger flux by increasing the membrane area;

[0005] 2: Increase the number of reverse osmosis membranes;

[0006] 3. Equipped with a high-flow-rate booster pump;

[0007] The above method has corresponding drawbacks:

[0008] 1. There is an upper limit to the roll area of ​​a single membrane in industry. If the roll area is to be increased, the costs of processes, filter bottles, etc. will increase significantly.

[0009] 2. Increasing the number of reverse osmosis filter cartridges will increase the size of the machine;

[0010] 3: High flow rate pumps are accompanied by high noise.

[0011] Due to limitations in membrane throughput, industrial film winding conditions, and machine size, further increasing throughput using this method would drastically increase costs. The method of increasing machine throughput by using high-throughput membranes and pumps has reached a bottleneck.

[0012] Therefore, it is essential to design a new water circuit system that can improve the flow rate of RO water purifiers. Utility Model Content

[0020] The aforementioned water circuit system for increasing the flow rate of an RO water purifier further includes: a post-filter cartridge, wherein the pre-filter cartridge, the booster pump, the reverse osmosis filter cartridge, the post-filter cartridge, and the heating module are connected in series.

[0021] In the aforementioned water system for increasing the flow rate of an RO water purifier, the inlet end of the pre-filter is connected to the inlet pipe.

[0022] The water outlet of the heating module is connected to a hot water pipe, and the hot water pipe has a hot water outlet.

[0023] The hot water pipe is connected to the inlet water pipe via the return pipe.
