[0036] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in connection with the accompanying drawings.

[0037] The following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in specific cases. In addition, in the description of the present application, unless otherwise specified, "multiple" means two or more. "And / or", the association between the associated objects, means that there can be three relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B, and the existence of B alone. The character " / " generally represents a "or" relationship between the associated objects before and after.

[0039] 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.

[0040] The first aspect of the present application provides a pure drinking system, which is a comprehensive system integrating water purification and convenient drinking water functions. The pure drinking system can be applied in places such as homes, offices, schools, and hospitals, and the embodiments of the present application do not make specific limitations.

[0041] Please refer to Figure 1 The pure drinking system includes a water purifier 3 and a water tank-free pipeline machine 2. The water purifier 3 has a raw water inlet 31 for connecting to tap water, and is used for deep filtration and purification treatment of tap water to make the water quality of the water source meet the standard of safe drinking or meet 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 uses a filter screen to filter out large particles of impurities in tap water; the precision filtering uses more advanced filtration technology to remove small molecules, harmful substances, etc. in tap water, and 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 from 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 cooling of the purified pure water, so that the user can accurately obtain drinking water and meet the user's different drinking water temperature requirements.

[0042] 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 to the water purifier 3, so that the faucet 4 can directly flow out the purified pure water from the water purifier 3. Further, considering that the water pressure in the water supply pipeline 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 due to 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 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.

[0043] 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 with the flow divider 1, so that the tap water supply pipeline can introduce tap water to the flow divider 1, and the excessively high and unstable water pressure of the tap water in the tap water supply pipeline can be adjusted and maintained within a preset pressure value range, so as to finally generate stabilized water and deliver the stabilized water to the water purifier 3, the water purifier 3 can 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 can be used as domestic water, and the pure water flowing to the tankless pipeline machine 2 can be drunk as direct drinking water.

[0044] However, in the related art, the pipeline machine has the problem of large overall size. This defect leads to insufficient flexibility in installation and difficulty in well adapting to various installation scenarios.

[0045] To solve the above problems, please refer to Figures 1 to 3 The application also provides a tankless pipeline machine 2 including a shell 21 and a waterway system 22.

[0046] The shell 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. The shell 21 has a mounting cavity 215 formed therein for accommodating various components.

[0047] The shell 21 has a water inlet 211 and a water outlet 212. The shell 21 can include a first shell 21 and a second shell 21, which can be detachably connected by clamping, screw connection or the like. The first shell 21 and the second shell 21 enclose the mounting cavity 215.

[0048] It should be noted that the water inlet 211 and the water outlet 212 described above can be in the form of a pipeline formed integrally on the shell 21, or in the form of separate components such as a hose or a connector. The first shell 21 and / or the second shell 21 has a relief opening, and the water inlet 211 and / or the water outlet 212 component can at least partially extend into the mounting cavity 215 through the relief opening and be connected with other components in the mounting cavity 215.

[0049] The waterway system 22 is disposed in the shell 21 and respectively communicates with the water inlet 211 and the water outlet 212, and at least comprises a first water inlet electromagnetic valve 2211, a negative pressure valve 2217 and a water pump 2214 disposed in sequence along the flow direction of water flow. The first water inlet electromagnetic valve 2211 is in communication with the water inlet 211,

[0050] The negative pressure valve 2217 is in communication with 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. Since the water tank is not designed, the waterway system 22 needs to be provided with the first water inlet electromagnetic valve 2211 and the water pump 2214 for cooperation. The first water inlet electromagnetic valve 2211 is responsible for controlling the on-off of water flow, and the water pump 2214 is responsible for providing the power of water flow. 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 the negative pressure (i.e. the pressure lower than the atmospheric pressure) in the pipeline. The negative pressure can cause the pipeline to be broken, the water hammer phenomenon (pressure impact caused by sudden stop or change of direction of water flow) or other damages. The negative pressure valve 2217 can maintain the 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 being damaged. The negative pressure valve 2217 has various ways to prevent the generation of negative pressure, such as air supplement method, pre-pressurization method, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in the related art, and will not be described herein.

[0051] In addition, the water tankless pipeline machine 2 based on the embodiments of the present application is designed without a water tank. On the one hand, it does not occupy too much space, so as to realize the miniaturization of the water tankless pipeline machine 2. On the other hand, since the water tankless pipeline machine 2 does not need to store water, it is not necessary to maintain the water temperature of the water tank, thereby reducing the energy consumption and avoiding the problem that bacteria are easily bred in the traditional pipeline machine with a water tank, and further improving the water quality of the water tankless pipeline machine 2.

[0052] The first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 are disposed along the length direction of the shell 21, and the length direction of the water pump 2214 is disposed in the same direction as the length direction of the shell 21. It can be understood that the shell 21 as a whole can be disposed in a rectangular body, so as to have a length direction. The outer contour of the water pump 2214 is disposed in a cylindrical shape, so that the axial direction of the water pump 2214 can be defined as the length direction.

[0053] Based on the above embodiments, the water tank-free design saves a lot of space for the pipeline machine to place the water tank, thus saving internal space from the root. At the same time, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217 and the water pump 2214 are arranged along the length direction of the shell 21, and the length direction of the water pump 2214 is consistent with the length direction of the shell 21. This layout effectively avoids the superposition of each component in the thickness direction. The orderly arrangement of each component makes the pipeline machine as a whole present a flat design. Compared with the traditional pipeline machine with a water tank and a messy internal layout, the water tank-free pipeline machine 2 greatly reduces the overall size, and the internal structure is more compact and reasonable. Whether it is a small family with limited space or an office with a compact layout, it can easily find a suitable installation location, significantly improving the applicability and popularity of the water tank-free pipeline machine 2 in different scenarios, and better meeting the diversified installation needs of people for high-quality water purification systems.

[0054] Referring to Figure 3 In some embodiments, the shell 21 is sequentially provided with a waterway installation area 2141 and an instant heating installation area 2142 along the length direction thereof, and the first water inlet electromagnetic valve 2211, the negative pressure valve 2217 and the water pump 2214 are all arranged in the waterway installation area 2141. The water tank-free pipeline machine 2 further comprises an instant heating device 25, which is in communication with the water pump 2214 and the water outlet nozzle 212, for heating the water flow flowing through the instant heating device 25. Among them, the layout of sequentially arranging the waterway installation area 2141 and the instant heating installation area 2142 along the length direction of the shell 21 makes the arrangement of each component more reasonable as a whole. The different functional areas are clearly divided, avoiding the messy stacking of components in space, effectively utilizing the internal space of the shell 21, and creating favorable conditions for realizing the flat design of the equipment.

[0055] It should be noted that the instant heating device 25 is generally used to quickly heat the water flow by using the electric heating element; that is, when the user needs hot water, the instant heating device 25 works, at this time, the water flow is quickly heated to a set stable temperature after flowing through the electric heating element in the instant heating device 25, so as to realize the hot water out of the water tankless pipeline machine. In addition, the embodiment of the present application uses the instant heating device 25 to heat the water flow, which can improve the energy efficiency of the water tankless pipeline machine 2; that is, the instant heating device 25 uses the instant heating technology, when the user needs hot water, the water tankless pipeline machine 2 can discharge hot water at a set temperature according to the user's demand, so that on the one hand, the heat loss can be reduced, on the other hand, the user does not need to wait for the heating time of the hot water, thereby saving the user's water receiving time. Furthermore, the type of the instant heating device 25 is not specifically limited in the embodiment of the present application. Exemplarily, the instant heating device 25 can be one of quartz tube heating type, thick film heating type and electromagnetic heating type. Among them, the quartz tube heating type uses quartz tube as heating body, the electric heating wire is wound on the outer wall of the quartz tube, the water flow in the quartz tube is heated by electric current, and this heating method has the advantages of fast heating speed, high temperature resistance and corrosion resistance. The thick film heating type uses thick film heating technology, the electric heating element is directly printed on the heating body to form a uniform heating film, and this heating method has the characteristics of high heating efficiency, fast thermal response speed and long service life. The electromagnetic heating type uses the principle of electromagnetic induction, generates eddy current in the heating body by electromagnetic field, thereby heating the water flow, and this heating method has the advantages of uniform heating, no open flame, safety and reliability. It should be noted that when the user needs to receive normal temperature water, the instant heating device 25 is in a non-working state, so that even if the water flow flows through the instant heating device 25, the electric heating element in the instant heating device 25 will not heat the water flow, so that the water tankless pipeline machine 2 flows out the normal temperature water.

[0056] Further, the shell 21 further comprises an electric control installation area 213, and the waterway installation area 2141 is located between the instant heating installation area 2142 and the electric control installation area 213. The water tankless pipeline machine 2 further comprises an electric control device 24, the electric control device 24 is installed in the electric control installation area 213, and is electrically connected with the first water inlet electromagnetic valve 2211, the water pump 2214 and the instant heating device 25.

[0057] The electric control device 24 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 speed, water temperature and other parameters to meet the different needs of users. 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, and the stability and reliability of the electric signal on the electric control device 24 can be ensured. 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. In addition, the electric control installation area 213, the waterway installation area 2141 and the instant heating installation area 2142 are arranged in sequence along the length direction of the shell 21, which makes the arrangement of each component more reasonable as a whole. The different functional areas are clearly divided, the components are not stacked in space, the internal space of the shell 21 is effectively utilized, and favorable conditions are created for the realization of the flat design of the equipment.

[0058] With reference to Figure 3Optionally, the waterway system 22 further comprises a water quantity sensor 2215 arranged in parallel with the water pump 2214 along the length direction of the water pump 2214 and electrically connected with the electric control device 24, the water quantity sensor 2215 is respectively communicated between the first water inlet electromagnetic valve 2211 and the water inlet 211, 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, so that the water quantity sensor 2215 is communicated with the water outlet nozzle 212. The embodiments of the present application do not make specific limitations on this. And the water quantity sensor 2215 comprises two polar plates, when there is enough water in the waterway system 22 flowing through the water quantity sensor 2215, at this time the water flow will flow through the two polar plates, so that the water quantity sensor 2215 generates an electric signal and sends a changed signal to the electric control device 24, because the electric signal generated by the water flow flowing through the two polar plates is inconsistent with the electric signal generated by the air or the less water flow flowing through the two polar plates, so that the electric control device 24 can determine the water quantity of the waterway system 22 at this time according to the received electric signal. It can be understood that when the instant heating device 25 is arranged in the water tankless pipeline machine 2, the instant heating device 25 is electrically connected with the electric control device 24, and the water quantity sensor 2215 can protect the instant heating device 25; that is, when the user needs to use hot water, the instant heating device 25 works, but due to insufficient water in the waterway system 22, the electric heating element in the instant heating device 25 is exposed to the air and continuously heated, so that the instant heating device 25 is in dry burning, which leads to overheating of the instant heating device 25, so that the instant heating device 25 is easily burned out, and the instant heating device 25 is easy to produce high-temperature steam in the heating process, if the water tankless pipeline machine 2 is used in the case of insufficient water in the waterway system 22, high-temperature steam is easy to be sprayed at the water outlet nozzle 212, which can cause harm to the user; therefore, the water quantity sensor 2215 arranged in the embodiments of the present application can monitor the water quantity information in the waterway system 22 in real time, and feed back the monitored water quantity information in the waterway system 22 to the control device of the water tankless pipeline machine 2, the control device determines the water quantity of the waterway system 22 according to the set water shortage logic, when the water quantity of the water quantity system is lower than the preset threshold, it indicates that the water in the waterway system 22 is insufficient, the control device controls the instant heating device 25 to stop working or reduces the power of the instant heating device 25, to prevent the occurrence of dry burning phenomenon, to protect the instant heating device 25, thereby ensuring the safety of the water tankless pipeline machine 2, to realize the protection of the water tankless pipeline machine 2. Furthermore, by intelligently controlling the power of the instant heating device 25, the water quantity sensor 2215 can realize the effect of energy saving and power saving, and reduce the electricity cost of the user.

[0059] Referring to Figure 3Optionally, the waterway system 22 further comprises a flow meter 2216 arranged in parallel with the water pump 2214 along the length direction of the water pump 2214 and electrically connected with the control device 24, the flow meter 2216 being connected with the first water inlet electromagnetic valve 2211 and the water inlet 211, or the first water inlet electromagnetic valve 2211 and the water pump 2214, or the water pump 2214 and the instant heating device 25 respectively, so that the flow meter 2216 is connected with the water outlet nozzle 212, which is not limited in the embodiments of the present application. The flow meter 2216 is used to detect the flow of the water flowing through the waterway system 22; that is, when the user inputs a quantitative water taking value to the water tankless pipeline machine 2, the first water inlet electromagnetic valve 2211 is opened, the water pump 2214 is operated, and the flow meter 2216 starts to detect the flow of the water flowing through the waterway system 22 and sends the flow to the control device of the water tankless pipeline machine 2. When the flow meter 2216 detects that the flow of the water flowing through the waterway system 22 reaches the water taking value required by the user, the control device controls the first water inlet electromagnetic valve 2211 to be closed, and the water pump 2214 and the flow meter 2216 stop working. In this way, the embodiments of the present application can improve the detection of the flow of the water flowing through the waterway system 22 and the accuracy of controlling the water discharge amount of the water tankless pipeline machine 2 by arranging the flow meter 2216. At the same time, the flow meter 2216 is placed more reasonably, which is convenient for the miniaturization of the water tankless pipeline machine 2.

[0060] With reference to Figure 3 In some embodiments, the water tankless pipeline machine 2 further comprises a sterilization device 23 arranged between the instant heating device 25 and the water outlet nozzle 212, or arranged upstream of the instant heating device 25. The embodiments of the present application are not limited in this regard. It can be understood that the sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water flow to ensure the safety and hygiene of the water quality, thereby improving the water quality of the water tankless pipeline machine 2. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, and such sterilization device 23 can effectively sterilize without producing chemical residues, thereby reducing pollution to the environment; in addition, these devices are usually designed compactly, easy to install and maintain.

[0061] With reference to Figure 3 and Figure 4Optionally, the waterway system 22 further comprises a mounting rack 217 connected in the housing 21, and the mounting rack 217 is at least partially mounted in the waterway mounting area 2141, and the first water inlet electromagnetic valve 2211, the negative pressure valve 2217 and the water pump 2214 are mounted on the mounting rack 217. The mounting rack 217 can be used as a mounting base for the components of the waterway system 22. During installation, the water pump 2214 and other components 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 fault position, facilitating replacement and maintenance of the components.

[0062] Further, the mounting rack 217 is provided with a first waterway 2171, and the water pump 2214 communicates with the instant heating device 25 through the first waterway 2171. In the embodiment of the application, 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, and the water outlet end of the water pump 2214 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 water pump 2214 and the instant heating device 25 are communicated through the waterway in the mounting rack 217, which can avoid the setting of a water pipe between the two, reducing the number of water pipes.

[0063] It can be seen that in the embodiment of the application, the water pump 2214 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 water outlet end of the water pump 2214 and the water inlet end of the instant heating device 25 are communicated. 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, the safety hidden danger of the water pipes and the wires being set together can be reduced or avoided, and the safety of the tankless pipeline machine 2 can be improved.

[0064] Referring to Figure 3 Optionally, part of the mounting rack 217 is located in the instant heating mounting area 2142, and the instant heating device 25 is connected with the mounting rack 217. In this way, the mounting rack 217 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 the assembly and maintenance of the instant heating device 25 and the tankless pipeline machine 2 as a whole, and facilitating the instant heating device 25 to communicate with the first waterway 2171.

[0065] Referring to Figure 5 and Figure 6In some embodiments, the waterway system 22 further comprises a check valve 2218 arranged at the water outlet nozzle 212 to prevent water dripping from the water outlet nozzle 212. It can be understood that the waterway system 22 further comprises a water outlet pipe 29 for connecting the instant heating device 25 and the water outlet nozzle 212. When the instant heating device 25 is used to heat the water in the waterway system 22, the instant heating device 25 is difficult to heat the water in the waterway system 22 to 100 degrees Celsius because the instant heating device 25 heats rapidly. Therefore, the check valve 2218 arranged 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 pipe 29, so that the water boils. In the process of boiling, water vapor can be arranged in the water outlet pipe 29. Since the water outlet pipe 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge water vapor, so that the water outlet nozzle 212 can flow out a stable water column.

[0066] Furthermore, the check valve 2218 can correspond to a one-way valve to prevent water flow from flowing backward in the water outlet pipe 29, and to protect other components in the waterway system 22, such as the water pump 2214, the instant heating device 25, etc., from being impacted and damaged by the reverse water flow.
