Description

Technical Field

[0001] The invention relates to a water fitting, in particular to a double-waterway double-valve integrated structure with two waterways, each waterway having a water valve for regulating the water flow. Background Art

[0002] Currently, many homes are equipped with water purifiers that purify tap water. Purified tap water, after purification, is then discharged through a countertop faucet for use. Currently, most faucets have a single outlet, requiring two faucets on the kitchen counter to deliver tap water and purified water, respectively. This results in a large number of faucets on the countertop, making installation and use more complicated. Some faucets also have multiple outlet functions, such as the applicant's prior Chinese patent application, "Multi-functional Faucet," with application number 2021222320445. The disclosed faucet valve body can deliver both purified and tap water, but only incorporates a valve in the tap water channel, not the purified water channel. Consequently, this existing faucet valve body can only regulate the flow rate of the tap water channel, not the purified water channel, and cannot achieve quantitative control of the purified water output. Therefore, improvements are necessary. Summary of the Invention

[0048] The principle of this embodiment is illustrated by using the dual-waterway, dual-valve integrated structure in conjunction with an existing water purifier (not shown). In the prior art, the purified water output by a water purifier is water that has been filtered through activated carbon and contains trace elements and minerals. This purified water is clean and hygienic, and users typically use it for washing vegetables and cooking. The pure water output by the water purifier is water that has been filtered through a reverse osmosis membrane and is of high purity. Users typically drink it directly or heat it to a suitable temperature before drinking. Therefore, in this embodiment, the first waterway can be used as the purified water path, and the second waterway as the pure water path.

[0049] The first water inlet interface 121 is connected to the purified water output end of the water purifier through a pipeline, and the first water outlet interface 131 can be connected to the faucet through a pipeline to realize the purified water output. The first water valve 2 can be used to manually adjust whether the purified water is output and the output amount. Manual adjustment is very convenient and suitable for the user's water use habits for washing vegetables and cooking.

[0050] The second water inlet interface 122 is connected to the pure water output end of the water purifier through a pipeline, and the second water outlet interface 132 can be connected to the faucet through a pipeline to realize pure water output. The second water outlet interface 132 can also be connected to the heating device through a pipeline, and output after being heated by the heating device. The second water valve 3 can automatically control whether pure water is output and the output amount. Through automatic control, pure water can be output in a quantitative manner to meet the drinking habits of different users.
