[0043] A preferred embodiment is given below, and the present disclosure is described more clearly and completely in conjunction with the accompanying drawings.

[0044] Example 1

[0045] In a specific embodiment of the present disclosure, a clean water generation system is provided, such as Figure 1As shown, the clean water generation system includes a controller (not shown in the figure), a clean water circuit 1 and a temperature control circuit 2, and the clean water circuit 1 is connected to the temperature control circuit 2 through a gas-liquid mixing valve 3;

[0046] A booster pump 11 is provided on the clean water circuit 1;

[0047] The temperature control water path 2 is provided with a tank body 21, a temperature sensor 22 and a water outlet 23 in sequence along the liquid flow direction, and an electric heating body 24 is also provided in the tank body 21;

[0048] The clean water circuit 1 is used to produce clean water, and the clean water flows into the tank body 21 through the booster pump 11 and the gas-liquid mixing valve 3;

[0049] The temperature sensor 22 is used to detect the temperature of the purified water in the tank 21;

[0050] The controller is used to receive a heating instruction, drive the electric heating body 24 to heat the purified water in the tank body 21, and discharge it through the water outlet 23;

[0051] The controller is also used to receive the collected purified water temperature and drive the booster pump 11 to adjust the pressure.

[0052] Specifically, a water purification unit is provided in the water purification circuit 1 for producing purified water based on the raw water entering the water purification system, and the produced purified water enters the temperature control circuit 2 via the booster pump 11. The tank body 21 on the temperature control circuit 2 may be a gas-liquid mixing tank, and an electric heating body 24 (for example, an electric heater) is provided in the tank body 21, and the electric heating body 24 can heat the liquid in the tank body 21, and the heated liquid is discharged via the water outlet 23 for use by the user, wherein a temperature sensor 22 is provided at the water outlet of the tank body 21, and the temperature sensor 22 detects the outlet water temperature of the tank body 21 and feeds back to the controller in real time. The water purification circuit 1 is connected to the temperature control circuit 2 via the gas-liquid mixing valve 3, so that the purified water produced by the water purification circuit 1 can enter the temperature circuit via the gas-liquid mixing valve 3, wherein the gas-liquid mixing valve 3 is a pressurized electromagnetic valve.

[0053] When the controller receives the user's water intake instruction, the gas-liquid mixing valve 3 is opened, so that the clean water produced by the clean water circuit 1 can flow into the tank 21 on the temperature control water circuit 2, and then be discharged through the water outlet 23 for the user to use. When the water intake instruction includes a heating instruction, the controller starts the electric heater 24 to heat the clean water in the tank 21, and receives the water outlet temperature feedback from the temperature sensor 22. If the water outlet temperature is lower than the user's required temperature, the pressure of the booster pump 11 is reduced to reduce the clean water flow entering the tank 21. If the water outlet temperature is higher than the user's required temperature, the pressure of the booster pump 11 is increased to increase the clean water flow entering the tank 21. By adjusting the flow of the booster pump 11, different water outlet temperatures are achieved under the power rated electric heater to meet the user's temperature control requirements.

[0054] In a specific practicable manner, as Figure 2 As shown, a bubbler 25 is also provided between the tank body 21 and the water outlet 23 in the temperature control water circuit 2;

[0055] The water purification circuit 1 is also provided with an air intake solenoid valve 12, which is connected to the booster pump 11 in sequence relative to the liquid flow direction;

[0056] The controller is also used to receive micro-nano bubble water production instructions, drive the air intake solenoid valve 12 to open, so that the gas enters the tank body 21 through the booster pump 11, and forms a gas-liquid mixture with the clean water in the tank body 21;

[0057] The bubbler 25 is used to generate micro-nano bubble water based on the gas-liquid mixture and discharge it through the water outlet 23 .

[0058] Specifically, the bubbler 25 can be a high-pressure bubbler for forming micro-nano bubble water from a gas-liquid mixture. The air intake solenoid valve 12 is a pressureless valve that can control the air flow, wherein the air intake solenoid valve 12 can also be provided with a one-way valve at the air inlet.

[0059] When the controller receives the micro-nano bubble water production instruction, the air inlet solenoid valve 12 and the gas-liquid mixing valve 3 are opened, so that a large amount of gas can flow into the tank body 21 to form a gas-liquid mixture with the clean water in the tank body 21. The gas-liquid mixture is provided to the user by the bubbler 25 to form micro-nano bubble water. The user can also set the temperature of the micro-nano bubble water. For the specific implementation principle, please refer to the above embodiment.

[0060] In a specific embodiment, Figure 3 As shown, the purified water circuit 1 also includes a filtration circuit 13 and a soft water circuit 14;

[0061] A reverse osmosis membrane filter element 131, a water tank 132 and a water purification solenoid valve 133 are provided in the filtration water circuit 13, and the booster pump 11, the reverse osmosis membrane filter element 131, the water tank 132 and the water purification solenoid valve 133 form a loop;

[0062] The soft water circuit 14 is connected to the filter water circuit 13 through the booster pump 11;

[0063] The soft water circuit 14 is used to produce soft water;

[0064] The water tank 132 is used to store the purified water filtered by the reverse osmosis membrane filter element 131;

[0065] The controller is also used to receive water production instructions and drive the gas-liquid mixing valve 3 and the water purification solenoid valve 133 to close to enter the water production mode.

[0066] Specifically, the reverse osmosis membrane filter element 131 can be an RO reverse osmosis filter element, which is a reverse osmosis membrane original, and the filtration accuracy reaches the nanometer level. The filter element has a water inlet, a clean water outlet and a wastewater outlet. A water-making solenoid valve 134 can be set before the water inlet of the filter element, and a flushing solenoid valve 135 can be set at the wastewater outlet of the filter element to achieve water inlet and wastewater control of the filter element. Among them, the water-making solenoid valve 134 is a pressurized solenoid valve, and the booster pump 11 can provide pressure for the RO reverse osmosis filter element so that it can normally make water. The flushing solenoid valve 135 can discharge a certain amount of wastewater when it is normally closed, and it is in a fully open state when it is normally open. A one-way valve can also be set at the water outlet of the flushing solenoid valve 135. The water tank 132 can be an open water tank 132, which can be a stainless steel square water tank 132 or a plastic water tank 132 made of PP material (a thermoplastic synthetic resin with stable performance), which is used to store clean water filtered by the reverse osmosis membrane filter element 131. The water purification solenoid valve 133 is a pressureless solenoid valve that can control the water outflow of the water tank 132.

[0067] When the controller receives the water production instruction, it drives the gas-liquid mixing valve 3 and the water purification solenoid valve 133 to close and the water production solenoid valve 134 to open, so that the soft water produced in the soft water circuit 14 enters the reverse osmosis membrane filter element 131 through the water inlet of the reverse osmosis membrane filter element, and the purified water obtained after filtration flows into the water tank 132 through the purified water outlet of the reverse osmosis membrane.

[0068] In a specific embodiment, a plurality of liquid level floats and float valves 1321 are provided in the water tank 132;

[0069] The liquid level float is used to detect the water level in the water tank 132. When the liquid level float reaches a preset height, the water inlet of the water tank 132 is closed;

[0070] The float valve 1321 is used to close the water inlet of the water tank 132 when the liquid level float fails.

[0071] In a specific embodiment, a high water level float 1322 and a low water level float 1323 are provided in the water tank 132, and a clean water replenishment solenoid valve 136 is provided between the water tank 132 and the reverse osmosis membrane filter element 131;

[0072] The height of the high water level float 1322 is higher than the height of the low water level float 1323 and lower than the height of the float valve 1321;

[0073] The height of the low water level float 1323 is higher than the water outlet 23 of the water tank 132;

[0074] The controller is also used to receive detection signals from the low water level float 1323 and the high water level float 1322 to drive the clean water replenishment solenoid valve 136 to open or close.

[0075] Specifically, the water tank 132 is also equipped with a float valve 1321, a low water level float 1323 and a high water level float 1322, wherein the water level of the low water level float 1323 is higher than the height of the water outlet 23 of the water tank 132, so that even if the water tank 132 is at a low water level, clean water can be guaranteed to flow out, and the height of the high water level float 1322 is lower than the height of the float valve 1321, so that when the high water level float 1322 fails, the float valve 1321 can effectively prevent water from entering the water tank 132.

[0076] In another specific embodiment, a high-pressure switch 137 may be further provided between the purified water replenishment solenoid valve 136 and the water tank 132 so as to cut off the power supply to the entire machine when the high-water level float 1322 fails, thereby further ensuring the health of the maintenance equipment.

[0077] In one embodiment, the top of the water tank 132 is also provided with an exhaust port 1324;

[0078] The exhaust port 1324 is used to keep the gas pressure in the water tank 132 at a preset pressure state.

[0079] Specifically, an exhaust port 1324 may be provided at the top of the water tank 132 to keep the gas pressure in the water tank 132 at a preset pressure state, for example, to keep the gas pressure in the water tank 132 consistent with the external atmospheric pressure.

[0080] In one specific embodiment, a composite filter element 141 and a central water softener 142 are sequentially arranged on the soft water circuit 14 along the liquid flow direction;

[0081] The central water softener 142 is used to produce soft water based on the raw water filtered by the composite filter element 141 .

[0082] Specifically, the composite filter element 141 can be a CPP composite filter element, which can be a composite filter element of a carbon rod and a polypropylene melt-blown filter element, or a composite filter element of a polypropylene and a carbon powder melt-blown filter element, which can effectively filter impurities, sediment and other particulate matter in the water, and can also adsorb residual chlorine and colloids. The central water softener 142 uses softening resin and salt regeneration to obtain soft water. The central water softener 142 has a water inlet, a soft water outlet and a drain. A water inlet solenoid valve 143 can be set before the water inlet of the central water softener 142, a drain solenoid valve 144 can be set at the drain of the central water softener 142, and a soft water outlet solenoid valve 145 can be set at the soft water outlet to control the production of soft water. Among them, the water inlet solenoid valve 143 is a pressurized solenoid valve that can control the water inlet of the entire water system, and the soft water outlet solenoid valve 145 is a pressurized solenoid valve. After being filtered by the composite filter element 141 , the raw water enters the central water softener 142 through the water inlet of the central water softener 142 to produce soft water, and then enters the filtering water path 13 through the soft water outlet to obtain purified water.

[0083] In a specific example, if Figure 3 As shown, the working principle of the clean water generation system is as follows:

[0084] ① Power-on flushing: control the water inlet solenoid valve, soft water outlet solenoid valve, booster pump, water making solenoid valve, and flushing solenoid valve to open, and close the others. The duration is 15 minutes. Power-on flushing is for the first use. Because there is no water inside the bottle and the central water softener, the flushing time will be longer.

[0085] ② Water flushing: control the water inlet solenoid valve, soft water outlet solenoid valve, booster pump and water production solenoid valve to open, and close the others, lasting for 45 minutes.

[0086] ③ Water production process: control the water inlet solenoid valve, soft water outlet solenoid valve, booster pump, water production solenoid valve, open the clean water replenishment solenoid valve, and close the others. At this time, the clean water will flow from the clean water pipe into the open water tank. At this time, the liquid level float monitors the current liquid level signal in real time. When the liquid level float detects a high water level, it stops replenishing water.

[0087] ④ Heating process: Users can adjust the outlet water temperature according to their own needs. When the temperature exceeds the temperature of normal temperature water, the electric heater should be turned on. The outlet water temperature required by the user is related to the outlet water flow of the booster pump. That is, when the heating power is constant, the higher the outlet water temperature, the smaller the outlet water flow of the booster pump. When the outlet water temperature is lower, the outlet water flow of the booster pump is greater.

[0088] ⑤ Full water flushing: Full water flushing should be carried out every time the water production stops, that is, when the liquid level float detects a high water level, the water inlet solenoid valve, soft water outlet solenoid valve, booster pump, water production solenoid valve, and waste water solenoid valve are all opened, and the others are all closed.

[0089] ⑥Micro-nano bubble water production process: When the micro-nano water extraction signal is given, the water inlet solenoid valve, soft water outlet solenoid valve, air inlet solenoid valve, water purification solenoid valve, gas-liquid mixing valve, and booster pump are all turned on, and the others are all closed. At this time, micro-nano bubble water can be obtained.

[0090] ⑦ Water replenishment process: When the liquid level float in the water tank detects that the water level is lower than the low water level, water production is required and the system enters the water production process.

[0091] ⑧ Overnight water drain: When the system detects that the machine has not been used for more than the preset time, for example, 24 hours, the system first needs to enter the full water flushing process, and then enter the water production flushing process, and finally control the opening of the water purification solenoid valve, booster pump, water production solenoid valve, and flushing solenoid valve until the system enters the water production process when the water tank detects a low water level.

[0092] ⑨Soft water regeneration process: Regardless of whether the system is in use or not, the central water softener will enter the regeneration mode at 3 am every day. When the central water softener enters the regeneration mode, the system will not drain the water overnight.

[0093] This embodiment effectively removes impurities in the water body through the reverse osmosis filter element. The water quality after filtration is almost pure water. At the same time, the pure water is mixed with soft water. The pure water and soft water pass through the micro-nano bubble machine to obtain "milk water". This water can effectively penetrate the pores of human skin and reach the deep layer of the skin. It can effectively clean the skin and can also adjust the water outlet temperature so that the water temperature meets the personalized needs of users and improves the user experience.

[0096] Among them, smart home appliances may include water dispensers, water purifiers, drinking water purifiers, beauty devices, countertop micro-nano bubble beauty devices, etc.

[0097] This embodiment effectively removes impurities in the water body through the reverse osmosis filter element. The water quality after filtration is almost pure water. At the same time, the pure water is mixed with soft water. The pure water and soft water pass through the micro-nano bubble machine to obtain "milk water". This water can effectively penetrate the pores of human skin and reach the deep layer of the skin. It can effectively clean the skin and can also adjust the water outlet temperature so that the water temperature meets the personalized needs of users and improves the user experience.
