[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] The embodiment of the present application provides a pure drinking system, which is a comprehensive system integrating water purification and convenient drinking water functions, wherein the pure drinking system can be applied to places such as families, offices, schools and hospitals, and the embodiment of the present application does not make specific limitations in this regard.

[0045] Please refer to Figure 1 , the pure drinking system comprises a water purifier 3 and a water tank-free pipeline machine 2. The water purifier 3 has a raw water inlet 31 for connecting tap water, and the water purifier 3 is used for deep filtration and purification treatment of the tap water, so that the water quality of the water source reaches the standard that can be safely drunk or meets the specific use requirements. The working principle of the water purifier 3 usually includes pre-filtering, precision filtering and post-treatment, etc. The pre-filtering mainly filters out large particle impurities in tap water by using a filter screen. The precision filtering uses more advanced filtration technology to remove small molecular substances, harmful substances and the like in tap water. The post-treatment may include activated carbon adsorption, etc. to improve the taste of water. The water purifier 3 also has a pure water outlet 32, and the water tank-free pipeline machine 2 is in communication with the pure water outlet 32, so that the purified pure water in the water purifier 3 can flow to the water tank-free pipeline machine 2 from the pure water outlet 32, and the water tank-free pipeline machine 2 is used for instant heating or refrigeration of the purified pure water, so as to facilitate users to accurately obtain drinking water and meet different drinking water temperature requirements of users.

[0046] Please continue to refer to Figure 1 In some embodiments, the pure drinking system can also include a faucet 4, which can be directly connected with the water purifier 3, so that the faucet 4 can directly flow out the purified pure water in the water purifier 3. Further, considering that the water pressure in the water supply pipeline for providing tap water to the water purifier 3 may change due to various factors (such as water supply peak period, pipeline maintenance, etc.), a pressure reducing valve is usually configured before the raw water inlet 31 of the water purifier 3, which not only stabilizes the water pressure in the water supply pipeline and reduces the water pressure entering the water purifier 3 in advance, but also avoids physical damage to the water purifier 3 caused by too high water pressure. In order to simultaneously distribute the purified pure water to the water tank-free pipeline machine 2 and the faucet 4 and improve the utilization efficiency of water, a flow dividing valve is usually configured at the rear end of the pure water outlet 32 of the water purifier 3, and the water inlet end of the water tank-free pipeline machine 2 and the water inlet of the faucet 4 are in communication with the flow dividing valve. When the user needs to take temperature-specific direct drinking water, such as drinking 5℃-15℃ ice water in hot summer, or taking 40℃-50℃ warm water to wash milk powder, or taking 90℃-99℃ hot water to make tea, etc., the user can open the water tank-free pipeline machine 2 to take. When the user needs to take domestic water to wash tableware or wash vegetables and fruits or wash clothes, the user can open the faucet 4 to take.

[0047] Please continue to refer to Figure 1However, the independent pressure reducing valve and the independent flow divider are respectively installed in the water purification system, which occupies more space and causes the pipeline layout to be messy, increasing the installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and the replacement of the pressure reducing valve and / or the flow divider in the limited space will greatly increase the operation complexity and maintenance cost. Therefore, in view of the existing problems, the water purification system can further include a flow divider 1, wherein the faucet 4, the tankless pipeline machine 2, the water purifier 3 and the tap water supply pipeline are all connected to the flow divider 1, so that the tap water supply pipeline can introduce tap water to the flow divider 1, regulate and maintain the excessively high and unstable water pressure of the tap water in the tap water supply pipeline within a preset pressure value range, and finally generate stabilized water and deliver it to the water purifier 3. The water purifier 3 will generate pure water after deep filtration and purification treatment of the stabilized water, and the pure water purified by the water purifier 3 can flow into the flow divider 1 and then be introduced to the tankless pipeline machine 2 and the faucet 4 through the flow divider 1. The pure water flowing to the faucet 4 will be used as domestic water, and the pure water flowing to the tankless pipeline machine 2 will be drunk as direct drinking water.

[0048] In the related art, the internal devices of the pipeline machine are electrically connected through wires, and a water path is formed through the water pipe connection. The pipeline structure is complex and is not conducive to assembly and maintenance. To solve the above technical problems, the tankless pipeline machine 2 of the embodiments of the present application is described in detail below.

[0049] Based on the tankless pipeline machine 2 of the embodiments of the present application, since it is designed without a water tank, on the one hand, it does not occupy too much space, achieving miniaturization of the tankless pipeline machine 2, and on the other hand, since the tankless pipeline machine 2 does not need to store water, it does not need to maintain the water temperature of the water tank, reducing energy consumption, and avoiding the problem of easy bacterial growth in the traditional tank pipeline machine, thereby improving the water quality of the tankless pipeline machine 2.

[0050] Please refer to Figures 2-3 The tankless pipeline machine 2 can include a housing 21, a water system 22, an electric control device 24 and an instant heating device 25.

[0051] The housing 21 is usually made of high-quality plastic materials such as high-density polyethylene, which has the characteristics of high strength, wear resistance, acid and alkali corrosion resistance, waterproofness, shock resistance and the like, and can maintain stable performance in various harsh environments, so as to ensure the normal work of the tankless pipeline machine 2.

[0052] The shell 21 is formed with a mounting cavity 215, which can be divided into an electric control mounting area 213, a waterway mounting area 2141 and an instant heating mounting area 2142 arranged in sequence. The electric control device 24 is mounted in the electric control mounting area 213, the waterway system 22 is mounted in the waterway mounting area 2141, and the instant heating device 25 is mounted in the instant heating mounting area 2142 and connected with the electric control device 24 through wires. The waterway system 22 is used to supply water to the instant heating device 25. The water tankless pipeline machine 2 further comprises the electric control device 24, which is used to control the working conditions of the waterway system 22 and the instant heating device 25. Through preset programs and algorithms, the electric control device 24 can accurately adjust the water flow rate, water temperature and other parameters to meet different needs of users.

[0053] It can be understood that the instant heating device 25 needs to be powered by strong electricity, and the strong electricity has the characteristics of high voltage and large current. The electric control device 24 needs to be powered by weak electricity, and the weak electricity has the characteristics of low voltage and small current. Therefore, the electric control device 24 and the instant heating device 25 are arranged separately in the length direction of the water tankless pipeline machine 2, so that the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal on the electric control device 24. In the length direction of the water tankless pipeline machine 2, the electric control device 24, the waterway system 22 and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the waterway system 22 to separate the electric control device 24 and the instant heating device 25, so that the thermal energy interaction interference is reduced.

[0054] The shell 21 has a water inlet 211 and a water outlet 212. The shell 21 can comprise a first shell and a second shell, which can be detachably connected by clamping, screw connection or the like. The first shell and the second shell enclose the mounting cavity 215.

[0055] It should be noted that the water inlet 211 and the water outlet 212 can be in the form of a pipeline integrally formed on the shell 21, or in the form of separate components such as a hose or a joint. The first shell and / or the second shell are formed with a clearance, and the water inlet 211 and / or the water outlet 212 components can at least partially extend into the mounting cavity 215 through the clearance and be connected with other components in the mounting cavity 215.

[0056] The waterway system 22 comprises a mounting bracket 217 and a pump assembly 2212 arranged on the mounting bracket 217. The water inlet end of the instant heating device 25 is communicated with the water outlet end of the pump assembly 2212, the water inlet end of the pump assembly 2212 is communicated with the water inlet 211, and the water outlet end of the instant heating device 25 is communicated with the water outlet 212.

[0057] The mounting rack 217 can be used as a mounting base for the components of the waterway system 22. During installation, the components such as the pump assembly 2212 can be mounted on the mounting rack 217 first, and then the mounting rack 217 is mounted in the mounting cavity 215, so that the assembly process is more simple and fast, and the installation difficulty and cost are reduced. When a component fails or needs to be maintained, the mounting rack 217 can be removed as a whole, so that the waterway system 22 can be taken out to observe the failure position, facilitating replacement and maintenance of the components.

[0058] In combination Figure 3 and Figure 4 , in the embodiment, the mounting rack 217 can also be configured in the form of a waterway plate, that is, a waterway is formed in the mounting rack 217. The first waterway 2171 is formed in the mounting rack 217, and an interface for connecting the first waterway 2171 is formed. The water outlet end of the pump assembly 2212 and the water inlet end of the instant heating device 25 are directly connected with the interface on the mounting rack 217 to communicate with the first waterway 2171. In this way, the pump assembly 2212 and the instant heating device 25 are communicated through the waterway in the mounting rack 217, which can avoid setting a water pipe between the two, and reduce the number of water pipes.

[0059] As can be seen, in the embodiment, the pump assembly 2212 of the waterway system 22 is mounted in the housing 21 through the mounting rack 217, the first waterway 2171 is formed in the mounting rack 217, and the first waterway 2171 communicates the water outlet end of the pump assembly 2212 and the water inlet end of the instant heating device 25. By forming a waterway on the mounting rack 217, the number of water pipes can be reduced, the complexity of the pipeline can be reduced, the assembly and maintenance can be facilitated, and the safety hazard of setting the water pipe together with the wire can be reduced or avoided, and the safety of the tankless pipeline machine can be improved.

[0060] In addition, during assembly, the components of the waterway system 22 can be mounted on the mounting rack 217 first, and then the mounting rack 217 is mounted in the housing 21, so that the assembly process is more simple and fast, the installation difficulty and cost are reduced, and the replacement and maintenance of the components are facilitated.

[0061] As shown in Figure 3 , in some embodiments, part of the mounting rack 217 is mounted in the waterway mounting area 2141, and the other part is mounted in the instant heating mounting area 2142, and is formed as a mounting base of the instant heating device 25. The instant heating device 25 is mounted on the mounting rack 217, and can be disassembled together with the mounting rack 217, facilitating assembly and maintenance of the instant heating device 25 and the tankless pipeline machine 2 as a whole, and facilitating communication of the instant heating device 25 with the first waterway 2171.

[0062] Optionally, the water outlet nozzle 212 is arranged at the bottom of the shell 21; that is, the water inlet end of the instant heating device 25 is below the instant heating device 25, and the water outlet end is above the instant heating device 25. Specifically, the water outlet nozzle 212 is located at the bottom of the shell 21, which is convenient for users to take water, especially for low space or children. The water inlet end and the water outlet end of the instant heating device 25 are arranged below and above the instant heating device 25, respectively, which can improve the utilization of space. In detail, since the water outlet nozzle 212 is located at the bottom of the shell 21, the water inlet end of the instant heating device 25 and the water outlet nozzle 212 are communicated through the water outlet pipeline 29. The water outlet nozzle 212 is arranged on the side of the mounting rack 217 away from the instant heating device 25, and the water outlet pipeline 29 is arranged in parallel with the instant heating device 25, which improves the utilization of space, makes the internal structure of the water tankless pipeline machine 2 more compact, and is beneficial to miniaturization design. Considering that the water outlet pipeline 29 is arranged in parallel with the instant heating device 25, the water inlet end of the water outlet pipeline 29 is arranged above, so that the water inlet end and the water outlet end of the instant heating device 25 are arranged below and above, respectively, thereby adapting to the arrangement direction of the water outlet pipeline 29.

[0063] In combination with Figure 1 and Figure 3 In an embodiment of the present application, the waterway system 22 further comprises a first water inlet electromagnetic valve 2211, a water quantity sensor 2215, a flow meter 2216, and a sterilization device 23. The first water inlet electromagnetic valve 2211, the water quantity sensor 2215, the flow meter 2216, and the sterilization device 23 are all mounted on the mounting rack 217, so as to facilitate assembly and maintenance.

[0064] Optionally, one end of the sterilization device 23 is communicated with the water outlet end of the pump assembly 2212, and the other end is communicated with the first waterway 2171. The sterilization device 23 is used for sterilizing the water flowing therethrough. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, etc. Such sterilization device 23 can effectively sterilize without generating chemical residues, thereby reducing pollution to the environment. The sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water outlet pipeline 29, ensure the safety and hygiene of water quality, and effectively reduce health problems caused by water quality problems. In an embodiment, a second waterway can be formed in the mounting rack 217, which communicates the water outlet end of the pump assembly 2212 and the sterilization device 23. In this way, the number of water pipes can be further reduced, the pipeline complexity is reduced, the pipelines in the shell 21 are further neat and orderly, assembly and maintenance are facilitated, and safety is improved.

[0065] In some embodiments, the sterilization device 23 can also be arranged on the water outlet pipeline 29, which will not be described in detail here.

[0066] In some embodiments of the present application, the mounting rack 217 is not limited to the first waterway 2171 and the second waterway, and can also be provided with another waterway to reduce the number of water pipes.

[0067] In the embodiments of the present application, the first water inlet electromagnetic valve 2211 is connected to the water inlet 211, and the first water inlet electromagnetic valve 2211 and the pump assembly 2212 are arranged side by side in the length direction in the waterway installation area 2141. Since there is no water tank design, the waterway system 22 needs to be provided with the first water inlet electromagnetic valve 2211 and the pump assembly 2212 for cooperation. The first water inlet electromagnetic valve 2211 is responsible for controlling the on-off of the water flow, and the pump assembly 2212 is responsible for providing the power of the water flow.

[0068] Please refer to Figure 1 With Figure 3 In some embodiments, the pump assembly 2212 can include a flow control pump and a water pump 2214. When the pump assembly 2212 includes the water pump 2214, the waterway system 22 further includes a negative pressure valve 2217. The negative pressure valve 2217 is arranged in the waterway installation area 2141 and can be connected to the mounting frame 217. The negative pressure valve 2217 is connected to the first water inlet electromagnetic valve 2211 and the water pump 2214 and is located between the first water inlet electromagnetic valve 2211 and the water pump 2214. When the water flow in the waterway system 22 is cut off or the water pump 2214 stops working, the negative pressure valve 2217 can prevent negative pressure (i.e., pressure lower than atmospheric pressure) from being generated in the pipeline. Negative pressure can cause pipeline rupture, water hammer phenomenon (pressure impact generated due to sudden stop or change of direction of water flow) or other damage. The negative pressure valve 2217 can maintain positive pressure in the pipeline or at least prevent the generation of negative pressure, thereby protecting the water pump 2214 and other components in the waterway system 22 from damage. The negative pressure valve 2217 can prevent the generation of negative pressure in various ways, such as air supplement method, pre-pressurization method, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in related technologies, and will not be described herein.

[0069] Of course, when the pump assembly 2212 is a flow control pump, the negative pressure valve 2217 can not be provided. The flow control pump is a pump that can maintain constant pressure when the flow changes. The flow control pump can stabilize the fluid state in the delivery pipeline by precisely controlling the flow and pressure of the water flow. In some cases, when the water flow in the delivery pipeline is cut off, the flow control pump can adjust its output flow to maintain the fluid pressure in the pipeline within a stable range, thereby avoiding the occurrence of negative pressure.

[0070] In some embodiments, the flow meter 2216 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or between the first water inlet electromagnetic valve 2211 and the water pump 2214, or between the water pump 2214 and the instant heating device 25. The flow meter 2216 is used to measure the flow of the water flow to provide accurate water consumption data for the user. By statistically analyzing the data collected by the flow meter 2216, the user can understand the water consumption rules of the tankless pipeline machine 2.

[0071] In some embodiments, the water quantity sensor 2215 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or between the first water inlet electromagnetic valve 2211 and the water pump 2214, or between the water pump 2214 and the instant heating device 25. The instant heating device 25 is configured to reduce power or stop working when the value detected by the water quantity sensor 2215 is lower than a preset value. The water quantity sensor 2215 can monitor the water quantity in the water path system 22 in real time, and stop or reduce the power of the instant heating device 25 in time when the water quantity is insufficient, so as to prevent dry burning and protect the safety of the equipment. By intelligently controlling the power of the instant heating device 25, the water quantity sensor 2215 can achieve the effect of energy saving and power saving, and reduce the electricity cost of the user.

[0072] In some embodiments, the part of the water path between the first water inlet electromagnetic valve 2211 and the pump assembly 2212 is formed by the mounting frame 217.

[0073] Please refer to Figures 1 to 3 In a specific embodiment, in the flow direction of the water flow, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water quantity sensor 2215, the flow meter 2216 and the pump assembly 2212 are sequentially communicated. The mounting frame 217 can also form a water path at one or more of the following positions: between the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217, between the negative pressure valve 2217 and the water quantity sensor 2215, between the water quantity sensor 2215 and the flow meter 2216, and between the flow meter 2216 and the pump assembly 2212, to communicate, thereby reducing the number of water pipes, reducing costs, and further improving the cleanliness of the pipes in the shell 21, facilitating assembly and maintenance, and also reducing the safety hazard of water pipe leakage.

[0074] Optionally, the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 are arranged at intervals in the height direction of the shell 21, the water quantity sensor 2215, the flow meter 2216 and the pump assembly 2212 are arranged at intervals in the height direction of the shell 21, and are located between the whole formed by the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 and the whole formed by the instant heating device 25 and the water outlet pipeline 29, and the pump assembly 2212 is located below the water quantity sensor 2215 and the flow meter 2216. The components such as the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water quantity sensor 2215, the flow meter 2216 and the pump assembly 2212 are partitioned according to functions, so that the role of each part is more explicit. When a fault occurs, the problem can be quickly located, facilitating maintenance and repair.

[0075] It should be noted that the first shell and the second shell of the present application are fixedly connected in the horizontal direction, and after the first shell is disassembled, the equipment of the waterway system 22 and the instant heating device 25 are arranged side by side in the second shell. In this way, the internal equipment can be seen at a glance, which is convenient for maintenance or replacement.

[0076] Please refer to Figure 5 and Figure 6 In some embodiments, the waterway system 22 further comprises a check valve 2218 arranged on the water outlet nozzle 212 and preventing the water flow from flowing backward in the pipeline, thereby protecting other components in the waterway system 22, such as the instant heating device 25, from being impacted and damaged by the reverse water flow. When the instant heating device 25 is used to heat the water in the waterway system 22 in the tankless pipeline machine 2, it is difficult for the instant heating device 25 to heat the water in the waterway system 22 to 100 degrees Celsius due to the rapid heating of the instant heating device 25. Therefore, the check valve 2218 designed at the water outlet nozzle 212 in the embodiments of the present application can play a pressure-bearing role to increase the boiling point of the water in the water outlet pipeline 29, so that the water boils. In the process of boiling, water vapor can be arranged in the water outlet pipeline 29, and since the water outlet pipeline 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge the water vapor, so that the water outlet nozzle 212 can flow out a stable water column.
