[0037] [[ID=:15]]Please refer to Figure 1 , Figure 1It is the water circuit structure diagram of the first implementation manner of the water purifier provided by the embodiments of the present application. The present application provides a water purifier, which includes a water purification device 10, a raw water pipeline 01, a pure water pipeline 02, a raw water branch 03, a first switch 20 and a second switch 30. Among them, the water purification device 10 includes a raw water inlet 101 and a pure water outlet 102; the raw water pipeline 01 accesses the raw water to the water purification device 10 through the raw water inlet 101, so that the water purification device 10 purifies the raw water; the pure water pipeline 02 accesses the pure water obtained by the water purification device 10 through the pure water outlet 102; the raw water branch 03 is arranged on the raw water pipeline 01; the first switch 20 and the second switch 30 are sequentially arranged between the raw water branch 03 and the raw water inlet 101; a water storage component 40 is further arranged on the raw water branch 03.

[0038] Among them, the water purification device 10 is a device for removing impurities and harmful substances in water to provide clean and safe drinking water. The water purification device 10 can be a countertop water purifier, an under-sink water purifier or a water purifying machine. A water purifier generally refers to a small household device designed to be connected to a faucet or a water pipe to provide clean drinking water for a family. The countertop water purifier and the under-sink water purifier are two common household water purification devices, which are different according to the installation positions. The countertop water purifier is installed above the sink and usually uses the water outlet of the faucet as the water source; since it does not need to be fixedly installed, the countertop water purifier is convenient to move and change positions. The under-sink water purifier is installed in the cabinet under the sink and connected to the water pipe, and it has stronger filtering ability and larger filtering capacity, such as reverse osmosis technology can be adopted. The raw water pipeline 01 is a pipeline connecting the raw water supply source (such as a municipal water supply system, well water or a water storage tank) and the water purification device 10. The main function of the raw water pipeline 01 is to transport the raw water to the water purification device 10 for purification treatment. The raw water pipeline 01 needs to be designed strong enough to withstand water pressure and wear in daily use. The pipeline material can be selected as non-toxic and corrosion-resistant materials, such as stainless steel, PVC or PEX pipes, to ensure that the water quality will not be secondarily polluted.

[0039] The raw water pipeline 01 is connected to the water purification device 10 through the raw water inlet 101 to ensure that the raw water can flow into the device smoothly. Optionally, in some embodiments of the present application, the raw water pipeline 01 may include a valve or a flow control device to adjust the water flow rate and pressure entering the water purification device.

[0040] The pure water pipeline 02 is a pipeline system that connects the pure water outlet 102 of the water purification device 10 to the user's usage points (such as kitchen faucets, water dispensers, etc.). The pure water pipeline 02 needs to use food-grade materials to ensure that it will not contaminate the water quality. The pipeline of the pure water pipeline 02 should have good sealing performance to prevent the intrusion of bacteria and microorganisms. The pure water pipeline 02 is connected to the water purification device 10 through the pure water outlet 102 to ensure that the purified water can flow out smoothly. The design of the pure water pipeline 02 needs to consider the water flow and pressure to meet the user's water usage requirements and avoid pipeline rupture caused by excessive pressure.

[0041] A first switch 20 and a second switch 30 can be installed on the raw water branch 03. The first switch 20 and the second switch 30 can control the flow direction and flow rate of the raw water to ensure that the raw water can enter the water purification device 10 along the designed path. The water storage component 40 provided on the raw water branch 03, through the coordinated use of the water storage component 40, the first switch 20, and the second switch 30, can prevent the raw water from directly causing excessive water pressure on the raw water pipeline 01, reduce the risk of pipeline rupture, and improve the safety of the system.

[0042] The first switch 20 and the second switch 30 can work independently or cooperatively to control the flow rate and flow velocity of the raw water entering the water purification device 10. By adjusting the opening degree of the switch, the water supply can be precisely controlled. When the water pressure is abnormal or during system maintenance, the raw water supply can be cut off by closing the first switch 20 and / or the second switch 30 to protect the water purification device from damage.

[0043] The water storage component 40 can temporarily store a certain amount of raw water. The water storage component 40 helps to balance the water pressure and prevent pipeline rupture or equipment damage caused by excessive water pressure.

[0044] Optionally, in some embodiments of the present application, please refer to Figure 2 , the water storage component 40 includes a pressure tank 401a and a solenoid valve 402a. Among them, the first end of the solenoid valve 402a is connected to the raw water pipeline through the raw water branch, and the second end of the solenoid valve 402a is connected to the pressure tank 401a.

[0045] The solenoid valve 402a, as a controllable valve, can quickly open or close the water flow through an electromagnetic signal to achieve precise control of the water flow. The first end of the solenoid valve 402a is connected to the raw water branch, and the second end is connected to the pressure tank 401a. Such a design allows the raw water to flow into the pressure tank after being controlled by the solenoid valve 402a for storage and pressure regulation. Through the control of the solenoid valve 402a, pipeline rupture or equipment damage caused by excessive water pressure can be prevented, and the safety of the system can be improved.

[0046] Optionally, in some embodiments of the present application, please refer to Figure 3, the water storage assembly 40 includes an airbag diaphragm 401b, a pressing member 402b, and a water storage chamber 403; wherein, both ends of the airbag diaphragm 401b are respectively arranged at the bottom of the water storage chamber 403, and the pressing member 402b is arranged below the airbag diaphragm 401b to control the working state of the airbag diaphragm 401b.

[0047] Optionally, the airbag diaphragm 401b is detachably arranged at the bottom of the water storage chamber 403 for easy replacement at regular intervals, thereby increasing the service life of the back suction valve. The pressing member 402b can be a spring or a stepper motor. When it is necessary to suck the water in the raw water pipeline 01, the first switch 20 and the second switch 30 are closed, and the pressing member 402b (whether it is a spring or a stepper motor) is used to rebound or pull back the airbag diaphragm 401b, so as to form a low-pressure area in the water storage chamber and suck the water in the raw water pipeline into the water storage chamber 403; when it is necessary to squeeze out the water in the water storage chamber 403, the pressing member 402b applies pressure to the airbag diaphragm 401b, pushing the airbag diaphragm to move downward, and squeezing out the water in the water storage chamber through the raw water branch 03, so as to purify the squeezed raw water through the water purification device 10.

[0048] Optionally, in some embodiments of the present application, please refer to Figure 4 , the water storage assembly 40 includes a back suction valve 401c and a water storage tank 402c;

[0049] Wherein, the first end of the back suction valve 401c is connected to the raw water pipeline 01 through the raw water branch 03, and the second end of the back suction valve 401c is connected to the water storage tank 402c. The back suction valve 401c has a two-end connection design, with the first end connected to the raw water branch 03 and the second end connected to the water storage tank 402c. By controlling the opening and closing state of the back suction valve 401c, the water flow between the raw water branch 03 and the water storage tank 402c can be adjusted. When it is necessary to suck the water in the raw water pipeline 01 into the water storage tank 402c, the back suction valve 401c can be operated to allow the water flow to pass from the raw water pipeline 01 through the raw water branch 03 and finally flow into the water storage tank 402c. The back suction valve 401c can adjust the pressure according to the pressure requirements of the system to prevent the water pressure from being too high or too low from affecting the normal operation of the system.

[0050] Optionally, in some embodiments of the present application, please refer to Figure 5 , the water purifier further includes a first control assembly 50, and the first control assembly 50 is electrically connected to the first switch 20 and the second switch 30 to control the opening and closing of the first switch 20 and the second switch 30. The first control assembly 50 is connected to the first switch 20 and the second switch 30 through electrical connection to achieve remote control and automated operation. The first control assembly 50 can control the opening and closing of the first switch 20 and the second switch 30 according to a preset program or real-time monitoring data, thereby controlling the water flow into and out of the water purification device.

[0051] Optionally, in some embodiments of the present application, please refer to Figure 6 The water purifier also includes a first water leakage detection component 61a and a second water leakage detection component 62a, wherein the first water leakage detection component 61a is connected to the raw water pipeline 01, and the second water leakage detection component 62a is connected to the pure water pipeline 02.

[0052] Specifically, the first water leakage detection component 61a is installed on the raw water pipeline 01, which is the initial water path entering the water purifier, and detects water leakage of the raw water. The second water leakage detection component 62a is installed on the pure water pipeline 02, which is the water path after purification, and detects water leakage of the pure water. The main function of the two components is to monitor whether there is water leakage in their respective pipelines, and immediately send a signal once an abnormality is detected. The water leakage detection component may include sensors, such as water immersion sensors, capacitive sensors or pressure monitoring sensors, which can sense the presence of water or changes in pressure. Once a water leakage is detected, the component will convert the signal into an electrical signal and transmit it to the first control component 50. After receiving the water leakage signal, the first control component 50 may perform the following operations according to the preset program:

[0053] Trigger the alarm system to remind the user to check.

[0054] The first switch 20 and / or the second switch 30 are automatically closed to cut off the water leakage source and prevent further water damage.

[0055] The linkage between the water leakage detection component and the first control component 50 ensures that the water purifier can respond quickly when a water leakage occurs, thereby improving the safety of the system.

[0056] Optionally, in some embodiments of the present application, an operation button is also provided on the outer surface of the water purification equipment 10, and the operation button is electrically connected to the first control component 50. When the operation button is pressed, the first control component 50 controls the opening and closing of the first switch 20 and / or the second switch 30.

[0057] Optionally, in some embodiments of the present application, the first switch 20 and the second switch 30 are pulse switches or normally open switches. Pulse switches and normally open switches are two common types of electrical switches, and their use in water purifier systems has the following characteristics and functions:

[0058] Pulse switches: These switches typically trigger upon receiving a brief electrical signal and then automatically return to their original state. In water purifiers, pulse switches can be used to control the flow of water momentarily, such as when a quick rinse is required or when testing water quality. Pulse switches can be combined with control systems to achieve precise water flow control.

[0059] Normally open switch: A normally open switch is in an open state when it does not receive a control signal and requires an active signal to close the circuit. In a water purifier system, a normally open switch can be used to ensure that water flow is not supplied in the default state until the system is ready to supply water.

[0060] Optionally, in some embodiments of the present application, refer to Figure 7 , the water purifier may further include a first water leakage detection component 61b, a second water leakage detection component 62b, and a second control component 63. Among them, the first water leakage detection component 61b is disposed on the raw water pipeline 01, the second water leakage detection component 62b is disposed on the pure water pipeline 02, and the second control component 63 is electrically connected to the first water leakage detection component 61b, the second water leakage detection component 62b, and the first switch 20 respectively.

[0061] The first water leakage detection component 61b monitors the water leakage condition of the raw water pipeline 01, while the second water leakage detection component 62b monitors the water leakage condition of the pure water pipeline 02, achieving multi-point monitoring. The second control component 63 is electrically connected to the two water leakage detection components, capable of receiving the water leakage detection signal in real time and responding quickly. The second control component 63 can automatically control the opening and closing of the first switch 20 according to the signals of the first water leakage detection component 61b and the second water leakage detection component 62b, cutting off or restoring the water supply. The water leakage detection component can trigger the second control component 63 when detecting an abnormality, realizing automatic closing of the water source to prevent water loss and potential equipment damage. The second control component 63 can be linked with other system components, such as automatically closing the heating system, to prevent danger in case of water leakage.

[0062] Optionally, in some embodiments of the present application, the first water leakage detection component 61b and the second water leakage detection component 62b are water leakage detection sensors or water pressure detection sensors.

[0063] Water leakage detection sensor: A water leakage detection sensor is specifically designed to detect the presence of water. They usually respond to the conductivity of water and trigger an electrical signal once water is detected.

[0064] Water pressure detection sensor: A water pressure detection sensor is used to monitor changes in water pressure. They can sense an increase or decrease in water pressure and convert it into an electrical signal.

[0065] Installation location: The first water leakage detection component 61b is installed on the raw water pipeline 01 to monitor water leakage or water pressure problems in the raw water supply. The second water leakage detection component 62b is installed on the pure water pipeline 02 to monitor water leakage or water pressure problems during the transportation of purified water.

[0066] If the first water leakage detection component 61b and the second water leakage detection component 62 are water leakage detection sensors, their main function is to detect and report water leakage.

[0067] If they are water pressure detection sensors, they monitor whether the water pressure is within a safe range instead of directly detecting water leakage.

[0068] The above is the water purifier provided by this application.

[0069] As can be seen above, when the water purifier makes water, the dual-stage heating module 20 is used to perform two-stage heating on the purified water in the water circuit. While ensuring large-flow water supply, the time for the water purifier to produce hot water is reduced, thereby improving the efficiency of supplying hot water. In addition, when the water purifier is turned off, the back suction module 40 is used to back suction the purified water remaining at the end of the water circuit, so that there is no residual water in the discharge channel of the water purifier. Furthermore, when the user receives hot water, the water discharged by the water purifier is always hot water. Thus, water resources are saved, and the user experience is improved.

[0070] The above-disclosed are only the preferred embodiments of this application. Of course, the scope of rights of this application cannot be limited thereby. Therefore, equivalent changes made according to the claims of this application still fall within the scope covered by this application.
