[0029] Referring to Figure 1 , Figure 1 A schematic diagram of a waterway system 10 in an embodiment of the present application is shown. The waterway system 10 provided by the embodiment of the present application is preferably used in a desktop water purifier, and can also be used in other types of water purifiers.

[0030] The water system 10 comprises a purified water path 200, a pure water tank 300, a hot water path 400, a cold water path 500 and a tea brewing unit 600. The purified water path 200 is connected to an external raw water source for purifying raw water to obtain pure water. The pure water tank 300 is connected to the purified water path 200 for storing pure water. The hot water path 400 is connected to the pure water tank 300 and comprises a first branch 401 and a second branch 402 in parallel, both of which are used to selectively make one of normal temperature water, warm water and hot water, and the second branch 402 is connected to a water outlet 11 of the purified drinking machine. The cold water path 500 is connected to the pure water tank 300 in parallel with the hot water path 400, for cooling pure water to obtain cold water. The tea brewing unit 600 has an inlet matched with the position of the outlet of the first branch 401, and the tea brewing unit 600 comprises a teapot for storing normal temperature water, warm water or hot water obtained by the first branch, and a heating unit for heating the normal temperature water, warm water or hot water as needed.

[0031] The water system 10 described above has the functions of brewing tea, making normal temperature water, warm water, hot water and cold water, and all the water is purified to meet the daily drinking water quality requirements. By providing the first branch 401, the water path of the tea brewing unit 600 is separated from the drinking water path, and the tea brewing function is realized by separate control. The second branch 402 in parallel is provided, and the second branch 402 integrates three types of water outlets, which are heated and controlled to discharge water of different requirements without the need to provide multiple water outlets 11, so that the drinking is convenient and easy to distinguish and control separately from the first branch 401 of the tea brewing.

[0032] In one embodiment, the purified water path 200 comprises a raw water tank 100 and a filter cartridge module 210, the raw water tank 100 is connected to the filter cartridge module 210 through a pipeline, and the filter cartridge module 210 is connected to the pure water tank 300 through a pipeline.

[0033] The raw water tank 100 is connected to a water source and pre-stores a part of raw water. To further improve the utilization rate of the water source, a more optimal implementation is that, as described in the foregoing embodiment, an overflow partition is arranged in the raw water tank 100 to divide the inner cavity of the raw water tank 100 into a concentrated water area and a raw water area. The bottom of the raw water area is connected to the filter cartridge module 210 through a pipeline.

[0034] In one embodiment, the water system 10 further comprises a waste water path 700 connected between the filter cartridge module 210 and the raw water tank 100, and the water flow direction of the waste water path 700 is opposite to that of the purified water path 200.

[0035] The wastewater channel 700 comprises a wastewater pipeline 710 and a wastewater valve 720 arranged on the wastewater pipeline 710. The outlet of the wastewater pipeline 710 is in communication with the bottom of the concentrated water area, that is, the initial raw water is stored in the raw water tank 100 for supplying water for filtration of the filter cartridge module 210, and the wastewater generated after filtration of the filter cartridge module 210 flows back to the concentrated water area through the wastewater pipeline 710, and the top of the overflow partition is provided with an overflow port, and when the returned wastewater reaches a certain height, it overflows to the raw water area through the overflow port for repeated filtration and utilization, thereby effectively improving the utilization rate of raw water. The wastewater outlet of the filter cartridge module 210 is in communication with the raw water tank 100 through the wastewater pipeline 710. The water channel system 10 of the embodiment provides more sufficient power for raw water filtration through the booster pump 220, and cooperates with the design of the rear-end double self-suction pump, so that the constant speed and constant flow of the water outlet of the purified drinking equipment can be realized by controlling the pump body operation program, which is beneficial to more accurate temperature control and improves the control accuracy of the outlet water temperature and single outlet water capacity of drinking water.

[0036] In one of the embodiments, the filter cartridge module 210 comprises a fine filter cartridge, a pre-filter cartridge and a post-filter cartridge arranged in part or in whole in combination, or the filter cartridge module comprises a fine filter cartridge, a pre-filter cartridge or a post-filter cartridge arranged separately. The fine filter cartridge can be a RO (Reverse Osmosis) filter cartridge, a nanofiltration filter cartridge or others, and the raw water can form purified water after filtration by the fine filter cartridge. The filter cartridge module 210 comprises at least one fine filter cartridge arranged separately or in combination. When the filter cartridge module 210 comprises a pre-filter cartridge and a fine filter cartridge, the raw water passes through the pre-filter cartridge and the fine filter cartridge in sequence, and the purified water is formed after filtration. When the filter cartridge module 210 comprises a post-filter cartridge and a fine filter cartridge, the raw water passes through the fine filter cartridge and the post-filter cartridge in sequence, and the purified water is formed after filtration. When the filter cartridge module 210 comprises a pre-filter cartridge, a post-filter cartridge and a fine filter cartridge, the raw water passes through the pre-filter cartridge, the fine filter cartridge and the post-filter cartridge in sequence, and the purified water is formed after filtration.

[0037] In other embodiments, when the filter cartridge module 210 does not comprise a fine filter cartridge, the filter cartridge module 210 comprises a pre-filter cartridge and a post-filter cartridge, and the raw water passes through the pre-filter cartridge and the post-filter cartridge in sequence, and the purified water is formed after filtration. The purified water has a lower cleanliness than the purified water, and is suitable for use in a use scenario with low water quality requirements. At this time, the purified water is obtained by the purified water channel, and the purified water is stored in the purified water tank.

[0038] It can be understood that the combination arrangement means that at least two filter cartridges are arranged in the same filter bottle, and the separate arrangement means that each filter cartridge is arranged in a separate filter bottle.

[0039] In one embodiment, the purified water path 200 includes a water quality detector 230 arranged upstream of the filter cartridge module 210, or arranged downstream of the purified water tank 300. To achieve detection of the raw water quality and the filtered water quality, it is more preferable to arrange the water quality detector on the raw water path and the filtered water path.

[0040] To facilitate timely monitoring of the water level in the water tank, it is more preferable to arrange a water level sensor in the raw water tank 100 and the purified water tank 300 respectively. The raw water tank 100 is provided with at least one water level monitor, particularly for monitoring the low limit water level, so as to prompt addition of raw water when the water level drops to a certain extent. The purified water tank 300 is provided with a water level sensor for monitoring the high limit water level and the low limit water level respectively, so as to prompt replenishment of the water source for continuous purification when the water level is low, and to prompt stopping of the filtration and purification for supplying water to the purified water tank 300 when the water level is high, so as to prevent the purified water from overflowing the water tank.

[0041] In one embodiment, the filter cartridge module 210 includes a fine filter, and the purified water path 200 further includes a booster pump 220 arranged between the filter cartridge module 210 and the raw water tank 100, which is used to pump the raw water in the raw water tank 100 to the filter cartridge module 210.

[0042] In one embodiment, a one-way valve 240 is arranged on the connecting pipeline between the outlet of the filter cartridge module 210 and the inlet of the purified water tank 300, so as to prevent backflow of the purified water to the filter cartridge module 210.

[0043] In one embodiment, the hot water path 400 includes a heating body 410 and a distribution valve 420, the heating body 410 is used to heat the purified water, the inlet of the distribution valve 420 is connected to the heating body 410, and the outlet of the distribution valve 420 is connected to the first branch 401 and the second branch 402 respectively.

[0044] Preferably, the heating body 410 is an instant heating body, the purified water enters the heating body 410 from the inlet, and after flowing through the heating body 410, the purified water has the required temperature at the outlet of the heating body 410. The first water outlet 11 of the water purifier simultaneously serves as a normal temperature water outlet, a warm water outlet and a hot water outlet. When the heating body 410 is heated to a first preset temperature, hot water flows out of the first water outlet 11; when the heating body 410 is heated to a second preset temperature, warm water flows out of the first water outlet 11; and when the heating body 410 is heated to a third preset temperature or not heated, normal temperature water flows out of the first water outlet 11. The first preset temperature is greater than the second preset temperature and greater than the third preset temperature. As an example, the first preset temperature is 60-100℃, the second preset temperature is 30-100℃, and the third preset temperature is 10-30℃.

[0045] Further, when the temperature of the pure water is close to (difference of ±5°C) or equal to the required normal temperature water temperature, the heating body 410 does not work, and the pure water only flows out through the first water outlet 11 after flowing through the heating body 410. When the temperature of the pure water is lower than the required normal temperature water temperature, the heating body 410 works, and the pure water only flows out through the first water outlet 11 after being heated to the required third preset temperature by the heating body 410.

[0046] The inlet and outlet of the heating body 410 are respectively provided with temperature detectors for monitoring the temperature change of the pure water flowing therethrough, so as to facilitate the control of the water outlet temperature. The outlet of the heating body 410 is connected to the inlet of the distribution valve 420 through the branch distribution pipe 411, and the outlet of the distribution valve 420 is respectively connected to the first branch 401 and the second branch 402, so that the first branch 401 and the second branch 402 are connected in parallel.

[0047] As preferred, the distribution valve 420 is a three-way valve, and at least one of the first branch 401 and the second branch 402 communicates with the heating body 410 through the distribution valve 420. When only one of the first branch 401 and the second branch 402 can communicate with the heating body 410, the distribution valve 420 is a two-position three-way valve, and the tea brewing function and the water drinking function of the water purifier are used alternatively. When both of the first branch 401 and the second branch 402 can communicate with the heating body 410, the distribution valve 420 is a one-in-two-way distribution valve, and the tea brewing function and the water drinking function of the water purifier are used simultaneously. If the tea brewing function and the water drinking function require water supply at different temperatures, the third branch can be connected to the pure water tank 300 to mix water, or the heating power of the tea brewing unit 600 can be adjusted to match the requirement. Further, in order to facilitate the overall control of the waterway system 10, the distribution valve 420 can be a controllable distribution valve 420, which can control and adjust the flow rate distributed to the first branch 401 and the second branch 402 respectively.

[0048] In one embodiment, the teapot of the tea brewing unit 600 is used to receive and store the pure water (warm water, warm water or hot water) output by the first branch 401, and the heating unit is used to heat or keep warm the pure water. When the pure water made by the first branch 401 is normal temperature water, the heating unit is used to heat the normal temperature water together with tea leaves or tea bags. When the pure water made by the first branch 401 is warm water, the heating unit is used to heat the warm water together with tea leaves or tea bags, or keep the warm water warm. When the pure water made by the first branch 401 is hot water, the heating unit is used to heat the hot water together with tea leaves or tea bags, or keep the hot water warm.

[0049] Further, the inlet of the teapot is directly communicated with the outlet of the first branch 401, and the teapot is provided with a through hole for docking the first branch 401, or the inlet of the teapot is matched with the outlet of the first branch 401, for example, the inlet of the teapot is separated and spaced apart from the outlet of the first branch 401, so as to facilitate taking away the teapot. The outlet of the first branch 401 is the second water outlet 12, which can be arranged side by side with the first water outlet 11.

[0050] In one of the embodiments, the tea brewing unit 600 is provided with tea leaves or tea bags, and the tea brewing unit 600 is provided with a water inlet directly communicated with the first branch 401. The tea brewing unit 600 receives normal temperature water or warm water from the first branch 401, and the normal temperature water or the warm water is mixed with the tea leaves or the tea bags and then is further heated. Further, the tea brewing unit 600 is provided with a placing groove for accommodating the tea leaves or the tea bags. The tea brewing unit 600 is in the shape of a teapot and can be made of transparent or translucent glass material, so as to facilitate the user to observe the inside of the cup body when brewing tea or making tea.

[0051] In one of the embodiments, the hot water making path 400 comprises a first liquid pump 430 arranged between the heating body 410 and the pure water tank 300. The first liquid pump 430 is located between the pure water tank 300 and the heating body 410. Further, a main distribution pipe 310 is arranged downstream of the pure water tank 300, one end of the main distribution pipe 310 is connected to the outlet of the pure water tank 300, and the other end is connected to the parallel hot water making path 400 and the cold water path. The first liquid pump 430 is located between the main distribution pipe 310 and the heating body 410. Preferably, the first liquid pump 430 can be a self-priming pump.

[0052] In one of the embodiments, the second branch 402 is provided with a gas-liquid separator 403. The outlet of the distribution valve 420 is communicated with the gas-liquid separator 403 through a pipeline, and the gas-liquid separator 403 is respectively provided with an exhaust port and a separated water port, and the separated water port is connected to the first water outlet 11 of the pure drinking machine.

[0053] In one of the embodiments, the cold water path 500 comprises a cold tank 510 for cooling pure water, and / or the cold water path 500 comprises a second liquid pump 530 arranged between the cold tank 510 and the pure water tank 300.
