Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and particularly to a water purifier water circuit system using a spherical pump and a water purifier adopting the system. Background Art

[0002] At present, most of the water purifiers on the market only filter raw water such as tap water to obtain pure water; if consumers want to obtain hot water, they need to be equipped with accessories such as kettles and pipeline machines to heat the pure water, and then obtain hot water. As time goes by, products integrating the heating function into the water purifier appear on the market, which are simply called integrated water purifier with heating function. The main heating methods are instant heating (instant heat) and storing pure water (filtered water) in a hot water tank for heating.

[0003] In the hot water tank solution on the market, that is, the integrated water purifier with heating function mainly uses a centrifugal pump to discharge the water in the hot water tank for users to use. The following problems exist in this system:

[0004] 1. Since the centrifugal pump has no self-priming ability, the centrifugal pump must be placed below the hot water tank, so that there is a height difference between the centrifugal pump and the hot water tank, so as to ensure that the water entering the centrifugal pump from the hot water tank has a certain pressure to avoid dry running. The centrifugal pump can only be set below the hot water tank, which greatly limits the layout of the whole system, is not conducive to the flexibility of the whole system, and will also increase the height of the water purifier.

[0005] 2. The centrifugal pump has a high rotational speed, so the centrifugal pump is sensitive to pressure, which will result in poor flow accuracy of the centrifugal pump in the integrated water purifier with heating function system. In order to control the flow rate, a heat-resistant flowmeter needs to be added to the system to feedback the flow information and adjust the rotational speed of the centrifugal pump in real time to ensure the flow accuracy. The heat-resistant flowmeter needs to work normally in a high-temperature environment for a long time, so it has high requirements for its performance and its cost is high. The heat-resistant flowmeter greatly increases the cost of the system, reduces the competitiveness of the product, and increases the complexity of the system.

[0006] 3. The hot water tank in the system using a centrifugal pump must have a large exhaust port to ensure the connection between the hot water tank and the atmosphere, so as to avoid the formation of a vacuum in the hot water tank after the hot water is discharged, which will lead to a decrease in the water pressure entering the water pump and exacerbate the dry running phenomenon of the water pump; the large exhaust port is also used to discharge the water vapor generated during the heating process of the hot water tank to avoid the occurrence of cavitation phenomenon caused by the water vapor entering the water pump. After the cavitation phenomenon occurs, the system noise will become larger and the flow rate will decrease, which will seriously affect the user experience. The larger the exhaust port, the lower the heat preservation performance of the hot water tank will be.

[0007] Therefore, there is an urgent need in this field to solve the problems of low flexibility, high cost and low heat preservation performance of the integrated water purifier with heating function system. Summary of the Invention

[0008] The main object of the present invention is to provide a water purification machine water circuit system and a water purification machine using a spherical pump, aiming to solve the problems of low flexibility, high cost, and low heat preservation performance of the pure heat system.

[0009] To achieve the above object, the water purification machine water circuit system using a spherical pump proposed by the present invention includes an inlet water circuit, an outlet water circuit, and a heating water circuit. The inlet of the filtration water circuit is connected to the outlet of the inlet water circuit; the inlet of the outlet water circuit is connected to the outlet of the filtration water circuit; a hot water tank and at least one spherical pump are arranged on the heating water circuit. The inlet of the hot water tank is connected to the front end of the outlet water circuit, and the spherical pump is connected to the outlet of the hot water tank. The spherical pump is used to discharge the hot water in the hot water tank to the outlet of the heating water circuit and to pump the residual water in the heating water circuit back to the hot water tank.

[0010] In one embodiment, the water purification machine water circuit system further includes an exhaust gas circuit. One end of the exhaust gas circuit is connected to the hot water tank, and the other end is used to communicate with the outside.

[0011] In one embodiment, the spherical pump is arranged below the hot water tank; or, the spherical pump is arranged on one side of the hot water tank.

[0012] In one embodiment, the top of the hot water tank has an exhaust port connected to the exhaust gas circuit, and the diameter of the exhaust port is in the range of 3 mm - 4.5 mm.

[0013] In one embodiment, a plurality of water level probes are arranged on the hot water tank; the plurality of water level probes respectively extend into the top, middle, and bottom of the hot water tank.

[0014] In one embodiment, a temperature detection module is installed on the top of the hot water tank; and / or, a temperature detection module is installed on the bottom wall of the hot water tank.

[0015] In one embodiment, a composite filter element, a booster pump, and a reverse osmosis filter element are arranged on the filtration water circuit; the composite filter element includes a pre-filter element and a post-filter element. The inlet of the pre-filter element is connected to the outlet of the inlet water circuit; the booster pump is respectively connected to the outlet of the pre-filter element and the inlet of the reverse osmosis filter element; the outlet of the reverse osmosis filter element is connected to the inlet of the post-filter element; the outlet of the post-filter element is connected to the outlet water pipeline.

[0016] In one embodiment, a water quality detection module and a temperature detection module are further arranged between the composite filter element and the reverse osmosis membrane.

[0017] In one embodiment, a flow meter, a one-way valve, a high-pressure switch, and a pipeline machine are sequentially arranged on the outlet water pipeline; and / or, the water purification machine water circuit system further includes a waste water circuit, and the waste water circuit is connected to the waste water outlet of the reverse osmosis filter element.

[0018] The present invention also provides a water purifier, which includes the above-mentioned water purifier water circuit system.

[0019] By adopting a spherical pump to replace the centrifugal pump, the technical solution of the present invention can greatly improve the self-priming ability of the water pump. Therefore, the position of the spherical pump can be set arbitrarily, not limited to being arranged below the hot water tank, and can be arranged at other positions, which improves the flexibility of system design, greatly reduces the layout difficulty of the system, and can reduce the height of the water purifier, thereby enhancing the competitiveness of the water purifier. The spherical pump is a positive displacement pump, and its flow accuracy can reach within 10%. Compared with the accuracy of the centrifugal pump within 20%, the present application can cancel the flow meter to greatly reduce the system cost, reduce the complexity of the system, and enhance the competitiveness of the product. Due to the improvement of the self-priming ability of the spherical pump, its exhaust hole can be reduced by more than 20% without worrying about cavitation problems. The reduction of the exhaust hole can greatly improve the heat preservation performance of the hot water tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0029] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, if there are descriptions such as "first" and "second" in the embodiments of the present invention, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] At present, the integrated water purifier and heater on the market uses a thermal tank and a centrifugal pump for heating and water supply. The following problems exist in this system:

[0032] Since a centrifugal pump does not have self-priming ability, the centrifugal pump must be placed below the hot water tank, so that there is a height difference between the centrifugal pump and the hot water tank, thereby ensuring that the water entering the centrifugal pump from the hot water tank has a certain pressure to avoid dry running. The centrifugal pump can only be set below the hot water tank, which greatly limits the layout of the entire system, is not conducive to the flexibility of the entire system, and will also increase the height of the water purifier.

[0033] The centrifugal pump runs at a relatively high speed, so the centrifugal pump is sensitive to pressure, which will result in poor flow accuracy of the centrifugal pump in the pure heat system. In order to control the flow rate, it is necessary to add a heat-resistant flow meter in the system to feedback the flow information and adjust the speed of the centrifugal pump in real time to ensure the flow accuracy. The heat-resistant flow meter needs to be used normally in a high-temperature environment for a long time, so it has high requirements for its performance and its cost is high. The heat-resistant flow meter greatly increases the cost of the system, reduces the competitiveness of the product, and increases the complexity of the system.

[0034] The hot water tank in the system using a centrifugal pump must have a large exhaust port to ensure that the hot water tank is connected to the atmosphere, so as to avoid the formation of a vacuum in the hot water tank after the hot water is discharged, which will cause the water pressure entering the water pump to decrease and exacerbate the dry running phenomenon of the water pump; the large exhaust port is also used to discharge the water vapor generated during the heating process of the hot water tank to avoid the occurrence of cavitation phenomenon caused by the water vapor entering the water pump. After the cavitation phenomenon occurs, the system noise will become larger and the flow rate will decrease, which will seriously affect the user experience. The larger the exhaust port, the lower the heat preservation performance of the hot water tank.

[0035] Therefore, it is necessary to design a new water purification machine water circuit system to solve the problems of low flexibility, high cost, and low heat preservation performance of the water purification machine water circuit system.

[0036] The present invention proposes a water purification machine water circuit system using a spherical pump.

[0037] Please refer to Figure 1 As shown in the figure, in an embodiment of the present invention, the water purification machine water circuit system using a spherical pump includes an inlet water circuit 10, a filtration water circuit 20, an outlet water circuit 30, and a heating water circuit 40; the inlet of the filtration water circuit 20 is connected to the outlet of the inlet water circuit 10. The inlet of the outlet water circuit 30 is connected to the outlet of the filtration water circuit 20. A hot water tank 41 and at least one spherical pump 42 are provided on the heating water circuit 40. The inlet of the hot water tank 41 is connected to the front end of the outlet water circuit 30. The spherical pump 42 is connected to the outlet of the hot water tank 41. The spherical pump 42 is used to discharge the hot water in the hot water tank 41 to the outlet of the heating water circuit 40, and to pump the residual water in the heating water circuit 40 back into the hot water tank 41.

[0038] Specifically, the water purification machine water circuit system of the present application is used in a water purification machine to provide hot water for users. It includes an inlet water circuit 10, a filtration water circuit 20, an outlet water circuit 30, and a heating water circuit 40. The inlet water circuit 10 is used to introduce external raw water into the system, and the external raw water can be a water source such as tap water. The filtration water circuit 20 is used to filter the raw water to obtain clean water. The heating water circuit 40 is used to heat the filtered water to provide it to users. The outlet of the inlet water circuit 10 is connected to the inlet of the filtration water circuit 20, and the outlet of the filtration water circuit 20 is connected to the inlet of the outlet water circuit 30. A hot water tank 41 and a spherical pump 42 are also provided on the heating water circuit 40, and the number of spherical pumps 42 is set to at least one. The inlet of the hot water tank 41 is connected to the front end of the outlet water circuit 30 to receive the water flowing out of the filtration water circuit 20. The spherical pump 42 is connected to the outlet of the hot water tank 41. When the spherical pump 42 rotates forward, it discharges the hot water in the hot water tank 41 to the outlet of the heating water circuit 40; when the spherical pump 42 rotates in reverse, it pumps the residual water in the heating water circuit 40 back into the hot water tank 41. It should be noted that there is a faucet at the end of the heating water circuit 40, and users can open the faucet to receive hot water for use. There will be some residual water in front of the faucet on the heating water circuit 40 and after the spherical pump 42. These residual waters will flow out of the faucet when the user opens the faucet next time, thus affecting the user experience. The reverse rotation of the spherical pump 42 can pump the residual water on the heating water circuit 40 back into the hot water tank 41 for reheating or heat preservation for the user's next use, improving the performance of the water purification machine and the user experience.

[0039] The technical solution of the present invention solves the problem of the installation position limitation caused by the lack of self-priming ability of the centrifugal pump in the traditional water purification machine by using the spherical pump 42 instead of the traditional centrifugal pump. The spherical pump 42 has self-priming ability and does not need to be placed at the bottom of the hot water tank 41 and can be installed at any position, thus increasing the flexibility and variability of the system. This not only simplifies the installation process but also reduces the requirements for the installation space of the system. The spherical pump 42 is a positive displacement pump, and its flow accuracy can reach within 10%, compared with the accuracy of the centrifugal pump within 20%. Therefore, the present application can cancel the heat-resistant flowmeter 31, greatly reducing the cost of the system, improving the competitiveness of the product, and reducing the complexity of the system. Due to the improvement of the self-priming ability of the spherical pump 42, its exhaust hole can be reduced by more than 20% without worrying about cavitation problems. The reduction of the exhaust hole can greatly improve the heat preservation performance of the hot water tank 41.

[0040] Please refer to Figure 4As shown, the spherical pump 42 includes a motor assembly 421 and a pump body 422. The shape of the pump body 422 is spherical or similar to a sphere, and components such as a piston and a turntable are accommodated inside it. The motor assembly 421 is drivingly connected to the pump body. The pump body 422 has two water outlets 423. The turntable is hinged to the piston and is also drivingly connected to the motor assembly. The motor assembly drives the turntable to rotate, thereby driving the piston to reciprocate in the spherical inner cavity, forming two working chambers with alternately changing volumes, so as to realize the pumping and discharging functions of the pump. The forward and reverse rotations of the motor assembly can achieve the conversion of the two water outlets, enabling the spherical pump 42 to pump water bidirectionally. Therefore, the spherical pump can not only send the hot water in the hot tank 41 to the outlet of the heating water circuit 40, but also pump the remaining water on the heating water circuit 40 back to the hot tank 41. Thus, the system of the present application can reduce the return pipeline, simplify the structure of the system, and reduce the cost of the overall system.

[0041] Please refer to Figure 2 As shown, in an alternative embodiment, the water purification machine water circuit system of the present application further includes an exhaust gas path 50. One end of the exhaust gas path 50 is connected to the hot tank 41, and the other end is used to communicate with the outside.

[0042] Specifically, in this embodiment, an exhaust gas path 50 is further provided, and its function is to discharge the gas in the hot tank 41 to prevent the gas in the hot tank 41 from affecting the normal discharge of water flow. By providing the exhaust gas path 50, the problem of discharging the gas in the hot tank 41 can be effectively solved, ensuring that the water in the hot tank 41 can be discharged smoothly, and improving the use efficiency and stability of the water purification machine.

[0043] The material of the exhaust gas path 50 should be selected as a material that is resistant to high temperature and corrosion to meet the discharge requirements of high-temperature water vapor in the hot tank 41. As a preferred implementation manner, a one-way valve 32 can be provided on the exhaust gas path 50 to prevent external air or impurities from entering the hot tank 41, further improving the stability and safety of the system.

[0044] In an alternative embodiment, the top of the hot tank 41 has an exhaust port for connecting the exhaust gas path 50, and the diameter of the exhaust port is in the range of 3 mm - 4.5 mm.

[0045] Specifically, an exhaust port is provided at the top of the hot water tank 41. This design connects to the outside through the exhaust port to prevent a vacuum from forming inside the hot water tank 41, thereby ensuring stable water pressure in the spherical pump 42 and avoiding the phenomenon of dry pumping. By controlling the diameter range of the exhaust port, effective exhaust can be achieved without affecting the heat preservation performance of the hot water tank 41. This technical solution effectively prevents the phenomenon of vacuum formation inside the hot water tank 41 due to water discharge by providing an exhaust port at the top of the hot water tank 41 and connecting it to the exhaust gas path 50, ensuring normal water pressure inside the spherical pump 42 and avoiding the problem of dry pumping. At the same time, by controlling the diameter range of the exhaust port, effective exhaust can be realized while maintaining the heat preservation performance of the hot water tank 41. The diameter of the exhaust port can be controlled through precision machining technology to ensure it is within the specified range. By controlling the diameter range of the exhaust port, the heat preservation performance of the hot water tank 41 is guaranteed, thereby improving the operation efficiency and reliability of the overall system.

[0046] Please refer to Figure 3 As shown, in an alternative embodiment, the spherical pump 42 is disposed on one side of the hot water tank 41; or the spherical pump 42 is disposed below the hot water tank 41.

[0047] Specifically, the spherical pump 42 is disposed on one side of the hot water tank 41, or the spherical pump 42 is disposed below the hot water tank 41. The technical features of these two position arrangements are aimed at optimizing the installation position of the pump to better realize the function of the pump. In this application, the spherical pump 42 is disposed on the side of the hot water tank 41 so that the operator can more easily access the pump body for necessary inspections and maintenance work. Therefore, this design can facilitate the maintenance and repair of the pump, and at the same time ensure the stable operation of the pump during operation, thus effectively solving the problem of the position arrangement of the spherical pump 42 in the hot water tank 41. This setting method can make the pump more stable during operation and reduce failures caused by vibration or other factors. Specifically, the spherical pump 42 can be fixed to one side of the hot water tank 41 through a bracket and connected to the outlet of the hot water tank 41 and the outlet of the heating water circuit 40 through pipes. In this way, maintenance and repair can be conveniently carried out without affecting the normal operation of the pump.

[0048] It should be noted that the spherical pump 42 can also be disposed below the hot water tank 41 or at other positions according to needs, which can effectively solve the layout of the spherical pump 42 to improve the flexibility of the system and ensure the performance of the overall system.

[0049] Please refer to Figure 2 As shown, in an alternative embodiment, a plurality of water level probes 60 are further provided on the hot water tank 41, and the plurality of water level probes 60 respectively extend into the top, middle, and bottom of the hot water tank 41.

[0050] Specifically, the water level probe 60 is a sensor commonly used to monitor the fluid height of the fluid inside the container. In this application, multiple water level probes 60 are installed on the hot tank 41. For example, three water level probes 60 are used. The three water level probes 60 extend to different depths inside the hot tank 41. One water level probe 60 extends to a position near the bottom wall of the hot tank 41, another water level probe 60 extends to the middle position of the hot tank 41, and the last water level probe 60 extends to a position near the top of the hot tank 41. The water volume inside the hot tank 41 can be accurately monitored through the three water level probes 60. When it is detected that the water volume inside the hot tank 41 is less than the preset value, a water replenishment operation can be triggered. It can send a signal to the control system to trigger the water replenishment operation to maintain the liquid level inside the hot tank 41 within the normal range. It can be understood that the number of water level probes 60 can be set to be more, and the specific number can be set according to actual needs.

[0051] In an alternative embodiment, a temperature detection module 70 is installed on the top of the hot tank 41; and / or, a temperature detection module 70 is installed on the bottom wall of the hot tank 41.

[0052] Specifically, in this embodiment, the top of the hot tank 41 can be on the lid of the hot tank 41 or at a position on the side wall of the hot tank 41 near the lid. A temperature detection module 70 for detecting the internal temperature of the hot tank 41 is provided at the top of the hot tank 41. Installing the temperature detection module 70 at the top of the hot tank 41 can quickly respond to the temperature change at the top of the hot tank 41. A temperature detection module 70 is also installed on the bottom wall of the hot tank 41, which can provide temperature information closer to the medium at the bottom of the hot tank 41. This is very important for understanding the heating state of the bottom wall of the hot tank 41, monitoring possible thermal stratification, or ensuring that the water also reaches the required temperature at the bottom. Especially in some scenarios that require uniform heating, the bottom temperature detection module 70 can help ensure that the water temperature is evenly distributed throughout the hot tank 41.

[0053] In terms of implementation, the temperature detection module 70 can adopt various sensor technologies, such as thermocouples, thermistors, or semiconductor temperature sensors. Specifically, thermocouples have the characteristics of fast response and high precision and are suitable for real-time monitoring of water temperature changes; thermistors have lower costs and are suitable for large-scale applications; semiconductor temperature sensors can provide higher integration and stability. Further, the temperature detection module 70 can transmit the detected temperature data to the control system wirelessly or wiredly, and the control system makes corresponding adjustments and controls according to the temperature data. In addition, the installation position of the temperature detection module 70 can be adjusted according to actual needs. For example, multiple temperature detection modules 70 are set at different heights of the hot tank 41 to achieve more accurate temperature monitoring.

[0054] By installing the temperature detection module 70 on the top and / or bottom wall of the hot water tank 41, the present application can achieve precise monitoring and control of the water temperature in the hot water tank 41. Compared with the prior art, the solution of the present application can effectively prevent the water temperature from being too high or too low, improving the safety and reliability of the water purifier. In addition, through the application of various temperature sensor technologies, the optimal implementation method can be selected according to different requirements, further enhancing the flexibility and adaptability of the system. Thus, the present application has significant advantages in ensuring user safety and normal operation of the equipment.

[0055] In an alternative embodiment, the filtration module includes a composite filter element 21, a booster pump 22, and a reverse osmosis filter element 23; the composite filter element 21 includes a pre-filter element 211 and a post-filter element 212, and the inlet of the pre-filter element 211 is connected to the outlet of the water inlet line 10; the booster pump 22 is respectively connected to the outlet of the pre-filter element 211 and the inlet of the reverse osmosis filter element 23; the outlet of the reverse osmosis filter element 23 is connected to the inlet of the post-filter element 212; the outlet of the post-filter element 212 is connected to the water outlet line.

[0056] The composite filter element 21, the booster pump 22, and the reverse osmosis filter element 23 in the filtration module are key technical features. The composite filter element 21 combines the pre-filter element 211 and the post-filter element 212. The pre-filter element 211 first performs preliminary filtration, the booster pump 22 increases the water pressure to enhance the filtration effect and efficiency, the reverse osmosis filter element 23 performs deep filtration, and the post-filter element 212 further purifies the water quality. Through the cooperation of these technical features, the problem of how to improve the filtration effect and efficiency of the water purifier is solved.

[0057] The preliminary filtration of the pre-filter element 211 can be achieved by different filter materials, such as activated carbon, PP cotton, etc., and the specific selection can be determined according to the water quality. The booster pump 22 can adopt different types of pumps, such as centrifugal pumps, plunger pumps, etc., and the specific selection can be determined according to the pressure and flow rate required by the system. The selection of the reverse osmosis filter element 23 can be adjusted according to the required filtration accuracy, and usually, a reverse osmosis membrane is used. The post-filter element 212 can further select an activated carbon filter element or other types of filter elements to further remove odors and improve the taste.

[0058] By introducing the combination of the composite filter element 21, the booster pump 22, and the reverse osmosis filter element 23, the present application significantly improves the filtration effect and efficiency of the water purifier. Compared with the prior art, the technical solution of the present application can more effectively remove impurities and harmful substances in the water, while improving the filtration speed and efficiency, meeting the user's demand for high-quality purified water.

[0059] In an alternative embodiment, a water quality detection module 80 and a temperature detection module 70 are further provided between the composite filter element 21 and the reverse osmosis filter element 23. In this application, the water quality detection module 80 and the temperature detection module 70 are arranged between the composite filter element 21 and the reverse osmosis filter element 23, enabling dual monitoring of water quality and temperature during the filtration process. This not only improves the intelligence level of the system but also enhances the safety and stability of the system. When the water quality or temperature is abnormal, the system can respond quickly and take appropriate measures to ensure that the output water quality always meets the standards and, at the same time, extend the service life of the filter element.

[0060] In an alternative embodiment, a flow meter 31, a check valve 32, a high-pressure switch 33, and a pipeline machine 34 are sequentially arranged on the water outlet pipeline; and / or, the water purification machine water circuit system further includes a wastewater water circuit 90, and the wastewater water circuit 90 is connected to the wastewater outlet of the reverse osmosis filter element 23.

[0061] In this application, by arranging the flow meter 31, the check valve 32, the high-pressure switch 33, and the pipeline machine 34 on the water outlet pipeline, precise control and management of the water flow are achieved. The flow meter 31 is used to detect the water flow rate, the check valve 32 prevents water from flowing back, the high-pressure switch 33 is used to control the water pressure, and the pipeline machine 34 is used for water transmission and distribution. The setting of the wastewater water circuit 90 is used to treat the wastewater generated by the reverse osmosis filter element 23, ensuring the efficient operation of the water purification machine. This technical solution solves the problems of flow control and wastewater treatment in the water circuit system of the water purification machine by reasonably configuring flow control devices on the water outlet pipeline and setting the wastewater water circuit 90, ensuring the stability and efficiency of the system.

[0062] The flow meter 31 can be of various types, such as a mechanical flow meter 31 or an electronic flow meter 31, and the specific selection can be determined according to actual application requirements. The design of the check valve 32 can prevent water from flowing back, ensuring the single direction of the water flow and the stability of the system. The high-pressure switch 33 can control the operation of the system by sensing changes in water pressure, avoiding system failures caused by excessive water pressure. The pipeline machine 34 can be used to deliver purified water to different water usage points, improving the convenience of using the water purification machine. The wastewater water circuit 90 can directly discharge the wastewater through a pipeline or perform secondary treatment to reduce water resource waste and environmental pollution.
