[0059] The drinking water purification system is mainly used in home kitchens, office tea rooms and other places to provide people with safe, healthy and convenient drinking water and domestic water.

[0060] In the related art, the current drinking water purification system on the market generally uses the purified water produced by the water purifier to supply the pipeline machine. However, the pipeline machine can only provide pure water to users. However, for the instant heating pipeline machine, since its instant heating device is limited by the heating power, the amount of water that can be heated is limited. In contrast, the water output of the water purifier is large, far exceeding the flow limit of the pipeline machine's instant heating device. Therefore, in order to cooperate with the large-flow water purifier, the pipeline machine usually needs to be equipped with a water tank as a buffer water storage device, and then the water is pumped from the water tank to the heating system for heating through a water pump. The water purification efficiency of the water purifier of this drinking water purification system is not only difficult to be fully utilized, but also the volume of the water tank is large, which becomes a key factor restricting the reduction of the volume of the whole machine. In addition, when users want to drink fresh mineral water, they need to set up a separate drinking water purification device, so that users need to switch between different devices to meet different drinking water needs, which reduces the convenience of use, and requires increased costs and occupies a certain amount of space.

[0061] Based on this, see Figure 1 The embodiment of the present application provides a drinking water purification system, which includes a diverter 1, a tankless pipeline machine 2, a water purifier 3 and a faucet 4, wherein the water purifier 3 has a raw water inlet 31 and a pure water outlet 32; the tankless pipeline machine 2 has a water inlet 211; and the faucet 4 has a pure water inlet 41, wherein the diverter 1 includes a valve housing 11, and the valve housing 11 includes a water inlet chamber 1147, a reflux chamber 1146 and a water outlet chamber 1148. The water inlet chamber 1147 is connected to the water source and the water purifier 3, so that water from the external water source enters the water purifier 3 through the diverter 1, and the pure water outlet 32, the pure water inlet 41 and the water inlet 211 are all connected to the water outlet chamber 1148, so that the pure water purified by the water purifier 3 can enter the faucet 4 and the tankless pipeline machine 2 through the diverter 1, so that the user can use the purified pure water by the water purifier 3 through different use ends.

[0062] It is understandable that the tankless pipeline machine 2 has an instant heating device 25 to heat pure water, and the amount of water purified by the water purifier 3 is large. The tankless pipeline machine 2 is limited by the heating efficiency of its instant heating device 25 and has a small water consumption. The water outlet chamber 1148 of the diverter 1 of the present application is connected to the water inlet chamber 1147 through the reflux chamber 1146. That is to say, the amount of water flowing from the water purifier 3 to the water outlet chamber 1148 is too large. When the water pressure in the water outlet chamber 1148 is relatively large, the water in the water outlet chamber 1148 can flow back to the water inlet chamber 1147 through the reflux chamber 1146, and enter the water purifier 3 again through the water inlet chamber 1147. In this way, the pressure-bearing capacity of the diverter 1 and the tankless pipeline machine 2 can be reduced, and the service life of the diverter 1 and the tankless pipeline machine 2 can be improved.

[0063] Specifically, please combine Figures 2 to 6 As shown, the diverter 1 includes a valve housing 11, which includes a valve body upper shell 116 and a valve body lower shell 117 that are interconnected. The interconnection here should be understood as a detachable connection, such as a bolt connection, a snap connection, etc., to facilitate the production of the valve body upper shell 116 and the valve body lower shell 117, and can also effectively improve the assembly efficiency and reduce the difficulty of assembly. In this embodiment, the valve body upper shell 116 and the valve body lower shell 117 are configured with a water inlet chamber 1147, a reflux chamber 1146 and a water outlet chamber 1148. The water outlet chamber 1148 can be connected to the water inlet chamber 1147 through the reflux chamber 1146. The water inlet chamber 1147 and the water outlet chamber 1148 are preferably located on the top side of the reflux chamber 1146. The valve body upper shell 116 is an integrally formed component, and / or the valve body lower shell 117 is an integrally formed component. Then, the valve housing 11 after the valve body upper shell 116 and the valve body lower shell 117 are assembled is more stable and has a higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in various parts of the valve housing 11, effectively preventing the valve housing 11 from rupturing. When subjected to external impact, it can better resist deformation. Compared with the combination of an independent pressure reducing valve and a diverter valve, such a diverter 1 is less likely to loosen or detach, reducing the risk of leakage of the diverter 1 and improving the sealing performance of the diverter 1, thereby ensuring that the sealing of the drinking water purification system is more stable during long-term use, and also simplifying the number of pipeline components (such as valves, conduits, etc.) and pipeline connections of the drinking water purification system, thereby helping to reduce the difficulty of installation and subsequent maintenance of the drinking water purification system. At the same time, the one-piece molding technology can realize the manufacture of the valve body through precise molds or processing techniques, and can also better control the dimensional accuracy and shape accuracy of the valve housing 11.

[0064] In this embodiment, please refer to Figures 2 to 5As shown, the diverter 1 is provided with a raw water inlet 1141, a pure water inlet 1143, a raw water outlet 1142, a first water supply port 1144 and a second water supply port 1145, wherein the raw water inlet 1141 is used to connect the water supply pipe to introduce tap water into the water inlet chamber 1147 of the valve housing 11, the raw water outlet 1142 is used to connect the water purifier 3 to deliver the pressure-stabilized water that flows through the water inlet chamber 1147 and is pressure-stabilized to the water purifier 3, the pure water inlet 1143 is used to connect the water purifier 3 to introduce the pure water purified by the water purifier 3, the first water supply port 1144 is used to connect the water inlet 211 to deliver the pure water to the water tankless pipeline machine 2, and the second water supply port 1145 is used to connect the pure water inlet 41 to deliver the pure water to the faucet 4. The raw water inlet 1141 is connected to the water inlet chamber 1147, the raw water outlet 1142 is connected to the reflux chamber 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the water outlet chamber 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143, and the second water supply port 1145 are all arranged on the valve body lower shell 117, and the raw water inlet 1141 and the first water supply port 1144 are arranged on the valve body upper shell 116.

[0065] Furthermore, if Figure 4 and Figure 5 As shown, the diverter 1 includes a pressure regulating component 16 and a diverter component 17, wherein the pressure regulating component 16 is disposed in the water inlet chamber 1147, and the diverter component 17 is disposed in the water outlet chamber 1148. In this way, the tap water supplied by the water supply pipe flows into the water inlet chamber 1147 from the raw water inlet 1141. If the water pressure in the urban water supply network changes due to various factors (such as water consumption peak and valley, maintenance and adjustment of the water supply system, etc.), for example, the water pressure is relatively low during the peak water supply stage, while the water pressure is relatively high during the low water consumption period such as at night. At this time, the pressure regulating component 16 will be able to reduce the pressure / stabilize the tap water flowing into the water inlet chamber 1147 to make it into stabilized water, and then output it to the water purifier 3 through the raw water outlet 1142 for filtration and purification, stabilizing the water pressure of the tap water within a suitable range to avoid the risk of overpressure damage or leakage of the water purifier 3 caused by the high water pressure acting on the filter element, water purification pipeline and other precision parts inside the water purifier 3, thereby increasing the service life of the water purifier 3. In addition, the tap water passes through the filter element of the water purifier 3 at a relatively stable flow rate, so that the filter element can fully absorb impurities such as organic matter and residual chlorine in the tap water, ensuring that the water purifier 3 always maintains the best filtering effect.

[0066] Understandably, if Figure 5As shown, the water purifier 3 generates pure water after deep filtration and purification of the pressure-stabilized water, which flows through the pure water inlet 1143 of the diverter 1 again and flows into the water outlet chamber 1148. Through the cooperation between the water outlet chamber 1148 and the diverter assembly 17, the pure water can be actually allocated and flow out from the first water supply port 1144 to the tankless pipeline machine 2, and from the second water supply port 1145 to the faucet 4. During the diversion of pure water, the excess pure water in the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter assembly 17 to form excess water. The reflux chamber 1146 can merge the pressure-stabilized water after the pressure-stabilized water flows through the pressure regulating assembly 16 with the excess water refluxed by the diverter assembly 17, and output it to the water purifier 3 from the raw water outlet 1142.

[0067] Next, the specific structure of the voltage regulating assembly 16 will be described in detail with reference to the accompanying drawings.

[0068] Please combine the specific Figure 4 , Figure 5 and Figure 6 As shown, the pressure regulating assembly 16 can divide the water inlet cavity 1147 into an air cavity 1153 and a liquid cavity 1611. Specifically, the space enclosed by the valve body upper shell 116 and the pressure regulating assembly 16 is formed into the air cavity 1153, and the pressure regulating assembly 16 is provided with a water injection guide hole 1612 and a pressure regulating water outlet 1613, and the water injection guide hole 1612 and the pressure regulating water outlet 1613 are both connected to the liquid cavity 1611.

[0069] For further details, please refer to Figure 4 , Figure 5 and Figure 6As shown, the inner wall of the air cavity 1153 is provided with a water injection conduit portion 1154 connected to the raw water inlet 1141 extending toward the inside of the air cavity 1153, and the water injection conduit portion 1154 is inserted into the water injection guide hole 1612 of the pressure regulating assembly 16. Specifically, a water injection flow channel 1155 connected to the raw water inlet 1141 is provided inside the water injection conduit portion 1154, and the water injection conduit portion 1154 is connected to the liquid cavity 1611 through the water injection flow channel 1155, and the port of the water injection flow channel 1155 used to connect to the liquid cavity 1611 is a water passing port. The valve housing 11 is provided with a pressure reducing chamber outlet 1151, so that the liquid chamber 1611 can be connected to the reflux chamber 1146 through the pressure reducing chamber outlet 1151, and the water pressure of the liquid chamber 1611 near the pressure regulating outlet 1613 is equal to the water pressure in the reflux chamber 1146, that is, the outlet pressure of the pressure regulating outlet 1613 of the pressure regulating assembly 16 is equivalent to the water pressure of the pressure-stabilized water delivered to the water purifier 3, and the water pressure of the liquid chamber 1611 near the water injection guide hole 1612 is equal to the water pressure of the water supply pipeline, that is, the inlet pressure of the water injection guide hole 1612 of the pressure regulating assembly 16 is the water pressure of the water supply pipeline. Since the pressure regulating assembly 16 includes a pressure regulating execution end arranged inside the liquid chamber 1611. In this way, when a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection guide hole 1612, the pressure regulating component 16 can produce a relative displacement along the central axis of the water injection conduit portion 1154 to change the throttling distance between the water passing port and the pressure regulating execution end.

[0070] Understandable, such as Figure 6 As shown, the whole process of tap water flowing into the liquid cavity 1611 is as follows: after the tap water flows into the water injection channel 1155 from the raw water inlet 1141, it will flow through the water port, the water injection guide hole 1612, the pressure regulating outlet 1613, the pressure reducing cavity outlet 1151 and flow to the reflux cavity 1146. When the outlet pressure of the pressure regulating assembly 16 increases (such as turning off the water purifier 3), the pressure on the side of the pressure regulating outlet 1613 will drive the pressure regulating assembly 16 to move along the central axis of the water injection conduit portion 1154 and toward the side close to the water port, and the pressure regulating execution end of the pressure regulating assembly 16 moves toward the water port, so that the throttling distance between the water port and the pressure regulating execution end is reduced, that is, the flow area between the water port and the pressure regulating execution end through which the tap water can pass is reduced until it reaches the position of force balance. When the outlet pressure drops (such as when the water purifier 3 is activated), the pressure on one side of the water injection guide hole 1612 will drive the pressure regulating component 16 to move along the central axis of the water injection conduit portion 1154 and toward the side away from the water port. The pressure regulating execution end of the pressure regulating component 16 moves away from the water port, thereby increasing the throttling distance between the water port and the pressure regulating execution end until the pressure regulating execution end is in a force balance state again.

[0071] Therefore, as the outlet pressure changes, the pressure regulating assembly 16 automatically makes corresponding displacements to change the throttling distance between the water port and the pressure regulating execution end, so as to achieve the purpose of stabilizing the pressure, thereby ensuring that the pressure supplied to the water purifier 3 remains basically unchanged. The structure is simple and compact, which is more convenient for subsequent disassembly and maintenance work by maintenance personnel. In addition, since the water injection conduit portion 1154 is inserted into the water injection guide hole 1612 of the pressure regulating assembly 16, not only the pressure regulating assembly 16 is more stable during the displacement process, but also the pressure regulating execution end can be accurately moved toward or away from the water port, thereby accurately adjusting the throttling distance between the water port and the pressure regulating execution end, so as to achieve the purpose of accurately regulating the pressure. In the process of assembling the pressure regulating assembly 16 to the valve housing 11, the water injection conduit portion 1154 can also insert and position the pressure regulating assembly 16, so as to improve the assembly efficiency and positioning accuracy.

[0072] The unexpected effect is that please combine Figure 4 and Figure 6 As shown, the tap water flowing in from the raw water inlet 1141 flows into the liquid chamber 1611 under the guidance of the water injection channel 1155, but does not fill the entire water inlet chamber 1147, which not only makes the pressure regulation response more timely and accurate, but also can further reduce the probability of tap water leaking from the assembly position between the pressure regulating component 16 and the valve housing 11, thereby improving the structural stability and reliability of the diverter 1.

[0073] Please refer to Figure 4 As shown, the pressure regulating assembly 16 includes a valve core assembly 162 and an elastic pressure regulating elastic member 163, that is, the pressure regulating elastic member 163 is made of a material that can be elastically deformed (such as silicone, rubber, etc.), the water injection guide hole 1612 and the pressure regulating water outlet 1613 are both arranged on the valve core assembly 162, and the valve core assembly 162 and the pressure regulating elastic member 163 are detachably connected to facilitate the disassembly and assembly of the valve core assembly 162 and the pressure regulating elastic member 163. If the pressure regulating elastic member 163 is damaged or loses its elasticity during long-term use, the pressure regulating elastic member 163 can be replaced separately, thereby reducing the maintenance cost of the pressure regulating assembly 16. Figure 5 As shown, the pressure regulating elastic member 163 is connected between the valve body upper shell 116 and the valve body lower shell 117. Further, when a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic member 163 can be deformed, and the valve core assembly 162 forms a relative slide along the extension direction of the water injection conduit portion 1154.

[0074] It can be understood that when the outlet pressure on the pressure-regulating water outlet 1613 side of the valve core assembly 162 increases, under the action of the outlet pressure, the pressure-regulating elastic member 163 produces elastic deformation toward the side close to the water port, and at the same time, it also cooperates with the valve core assembly 162 to move along the central axis of the water injection conduit portion 1154 and toward the side close to the water port. When the inlet pressure on the water injection guide hole 1612 side of the valve core assembly 162 decreases, under the action of the outlet pressure and the deformation recovery of the pressure-regulating elastic member 163, the pressure-regulating elastic member 163 resets toward the side away from the water port, and at the same time, it also cooperates with the valve core assembly 162 to move along the central axis of the water injection conduit portion 1154 and toward the side away from the water port.

[0075] As a preferred method of this embodiment, please refer to Figure 6 As shown, the valve core assembly 162 includes a valve core limiting sleeve 1621 and a valve core base 1622, wherein the valve core limiting sleeve 1621 is provided with a first guide hole 16121, and the valve core base 1622 is provided with a second guide hole 16122, the first guide hole 16121 and the second guide hole 16122 constitute a water injection guide hole 1612, the central axis of the first guide hole 16121 and the central axis of the second guide hole 16122 are collinear, ensuring that the water injection conduit portion 1154 can be sequentially inserted into the first guide hole 16121 and the second guide hole 16122, and the pressure regulating water outlet 1613 is provided on the valve core base 1622. Further, as Fig.13 and Fig.14 As shown, the valve core limiting sleeve 1621 is sleeved on the outside of the valve core base 1622, and part of the pressure regulating elastic member 163 is sandwiched between the valve core limiting sleeve 1621 and the valve core base 1622. Preferably, the valve core base 1622 is provided with an external thread section 1625, and the valve core limiting sleeve 1621 is provided with an internal thread section 1626 threadedly connected to the external thread section 1625, and the valve core limiting sleeve 1621 is threadedly fixed to the valve core base 1622, which not only realizes the purpose of detachable connection between the valve core assembly 162 and the pressure regulating elastic member 163, but also makes the assembly more convenient and efficient.

[0076] Specifically, Figure 6 As shown, the inner diameter of the port of the valve core limit sleeve 1621 near the end of the pressure regulating elastic member 163 is larger than the diameter of the valve core base 1622, so the valve core limit sleeve 1621 near the end of the pressure regulating elastic member 163 and the outer side wall of the valve core base 1622 cooperate to form a clamping space. Fig.13 , Fig.14 and Fig.15As shown, the above-mentioned pressure-regulating elastic member 163 includes an elastic member body 1631, and a clamping protrusion 1632 extending from the elastic member body 1631 toward the clamping space, wherein the elastic member body 1631 and the clamping protrusion 1632 both extend along the circumference of the valve core base 1622, and the end of the elastic member body 1631 close to the valve core base 1622 and the clamping protrusion 1632 are formed into an elastic sleeve hole 164, the valve core base 1622 is inserted into the elastic sleeve hole 164 of the pressure-regulating elastic member 163, and the clamping protrusion 1632 is clamped between the valve core limit sleeve 1621 and the valve core base 1622. With such a configuration, the valve core limit sleeve 1621 and the valve core base 1622 cooperate to clamp the pressure-regulating elastic member 163, making the connection between the pressure-regulating elastic member 163 and the valve core assembly 162 more stable, thereby ensuring that during the elastic deformation of the pressure-regulating elastic member 163 and the movement of the valve core assembly 162, the pressure-regulating elastic member 163 and the valve core assembly 162 will not be separated, thereby improving the stability of the pressure-regulating assembly 16 during operation.

[0077] Further, please refer to Fig.15 As shown, the clamping protrusion 1632 is provided with a second fastening protrusion 16332, and the second fastening protrusion 16332 is integrally formed with the clamping protrusion 1632, so that the second fastening protrusion 16332 is clamped between the clamping protrusion 1632 and the valve core limiting sleeve 1621, thereby increasing the friction resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621, and effectively preventing the clamping protrusion 1632 from escaping from the clamping space. Of course, the second fastening protrusion 16332 can also be provided on the valve core limiting sleeve 1621, and the valve core limiting sleeve 1621 and the second fastening protrusion 16332 are integrally formed, which can also increase the friction resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621.

[0078] Further, please refer to Fig.16 As shown, the clamping protrusion 1632 is further provided with a third fastening protrusion 16333, the third fastening protrusion 16333 is integrally formed with the clamping protrusion 1632, and the third fastening protrusion 16333 is clamped between the clamping protrusion 1632 and the valve core base 1622, thereby increasing the friction resistance between the clamping protrusion 1632 and the valve core base 1622, and further preventing the clamping protrusion 1632 from escaping from the clamping space. Of course, the third fastening protrusion 16333 can also be provided on the valve core base 1622, and the third fastening protrusion 16333 is integrally formed with the valve core base 1622, which can also increase the friction resistance between the clamping protrusion 1632 and the valve core base 1622.

[0079] It should be noted that the second fastening protrusion 16332 can be combined with the third fastening protrusion 16333, which can not only better prevent the clamping protrusion 1632 from escaping from the clamping space, but also enable the clamping protrusion 1632 to be more compactly assembled in the clamping space.

[0080] In addition, please refer to Figure 6 As shown, the pressure regulating assembly 16 also includes a valve core sealing ring 165, a valve core limiting sleeve 1621 and a valve core base 1622 cooperate to form a valve core sealing cavity, and the valve core sealing ring 165 is sleeved on the water injection conduit portion 1154 and embedded in the valve core sealing cavity to better prevent tap water from leaking into the air cavity 1153 from between the water injection guide hole 1612 and the water injection conduit portion 1154.

[0081] In this embodiment, in order to ensure that the pressure regulating elastic member 163 can be connected between the valve body upper shell 116 and the valve body lower shell 117 more quickly and more firmly, the inventor provides a preferred method. Figures 2 to 6 As shown, the elastic member body 1631 is clamped between the valve body upper shell 116 and the valve body lower shell 117. Fig.15 As shown, the valve body lower shell 117 is provided with a housing slot, which extends along the circumference of the valve body lower shell 117, and the pressure regulating elastic member 163 extends toward the inside of the housing slot to form a sealing buckle 1635, which extends along the slot length direction of the housing slot, and the sealing buckle 1635 is inserted into the housing slot. Such a configuration can not only ensure that the pressure regulating elastic member 163 is more compactly and firmly clamped on the valve housing 11, but also achieve the premise of facilitating the assembly of the pressure regulating assembly 16, and the pressure regulating assembly 16 is more firmly installed on the valve housing 11. At the same time, it also ensures the sealing of the connection position between the pressure regulating elastic member 163 and the valve housing 11, prevents water from seeping out of the valve housing 11, and also avoids the problem of water infiltrating into the air cavity 1153 and causing the parts in the air cavity 1153 to rust and fail. It should be noted that the shell slot can also be provided on the valve body upper shell 116, or the valve body upper shell 116 and the valve body lower shell 117 are both provided with shell slots, which can be set and adjusted according to structural design and design requirements.

[0082] Further, please refer to Fig.15As shown, the sealing buckle part 1635 is provided with a first fastening protrusion 16331, and the first fastening protrusion 16331 is integrally formed with the sealing buckle part 1635, so that the first fastening protrusion 16331 is sandwiched between the sealing buckle part 1635 and the housing slot, thereby increasing the friction resistance between the sealing buckle part 1635 and the housing slot, so that the sealing buckle part 1635 is more firmly inserted into the housing slot, and the sealing buckle part 1635 is better prevented from being separated from the housing slot. Of course, the first fastening protrusion 16331 can also be provided on the slot wall of the housing slot, which can also increase the friction resistance between the sealing buckle part 1635 and the housing slot.

[0083] As a preferred method of this embodiment, see Fig.15 As shown, the elastic member body 1631 is provided with a deformation adjustment groove 1634, which is in a U-shaped structure, and the notch of the deformation adjustment groove 1634 is preferably oriented toward the air cavity 1153. Figure 6 As shown, the deformation adjustment groove 1634 is formed by bending the elastic member body 1631 between the valve core base 1622 and the valve housing 11, and the deformation adjustment groove 1634 extends along the circumference of the valve core base 1622. This not only creates enough space for the elastic member body 1631 during elastic deformation, but also provides a larger elastic deformation range within a limited space, thereby increasing the elastic capacity of the pressure regulating elastic member 163.

[0084] As a preferred method of this embodiment, please refer to Fig.13 As shown, the valve core base 1622 includes a valve flap plug 1623, and the valve flap plug 1623 serves as the pressure regulating execution end of the pressure regulating assembly 16. Fig.14 As shown, the valve flap plug 1623 is provided with a valve flap support beam 1624 extending toward the cavity wall of the liquid cavity 1611, and the valve flap support beam 1624 extends to the body of the valve core base 1622 and is fixedly connected to the body of the valve core base 1622. In order to ensure that the valve core base 1622 has good structural strength and facilitate the production of the valve core base 1622, the valve flap plug 1623, the valve flap support beam 1624 and the body of the valve core base 1622 are integrally formed. Among them, the valve flap support beam 1624 can be selected as one, and the valve flap support beam 1624 extends along the circumference of the valve flap plug 1623, and the valve flap support beam 1624 is evenly provided with a plurality of water flow holes along the circumference of the valve flap plug 1623, so that the pressure-stabilizing water can flow through the water flow holes. Alternatively, there are preferably multiple valve flap support beams 1624, which are evenly distributed around the valve flap plug 1623, and two adjacent valve flap support beams 1624 are arranged at intervals to facilitate the flow of pressure-stabilizing water through the valve flap plug 1623.

[0085] In order to avoid the valve plug 1623 and the water port of the water injection conduit 1154 from being in rigid contact and reduce the noise of the diverter 1, please refer to Figure 6 , Fig.13 and Fig.14 As shown, the valve flap plug 1623 includes a valve flap support 16231 and an elastic plug elastic member 16232. The plug elastic member 16232 can be made of silicone material. The valve flap support 16231 is provided with a valve flap embedding groove 16233 for embedding the plug elastic member 16232. The valve flap support 16231 is fixedly connected to the main body of the valve core base 1622 through a valve flap support beam 1624.

[0086] In this embodiment, please refer to Figures 4 to 6 As shown, the pressure regulating assembly 16 also includes a pressure regulating spring 166, which is located in the air cavity 1153, and one end of the pressure regulating spring 166 abuts against the inner wall of the air cavity 1153, and the other end of the pressure regulating spring 166 abuts against the valve core assembly 162. When a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic member 163 and the pressure regulating spring 166 are both deformed.

[0087] On the one hand, during the pressure regulation process, the pressure regulating spring 166 can assist the pressure regulating elastic member 163 to return to the initial position or the equilibrium position after the pressure changes. That is, the pressure regulating spring 166 can use its own elastic force to push the pressure regulating elastic member 163 back to a certain position, and make the valve core assembly 162 move accordingly, returning to a state close to the original state, thereby ensuring the stability of the outlet pressure. Moreover, the elastic coefficient of the pressure regulating spring 166 is relatively stable, which helps to more accurately control the deformation of the pressure regulating elastic member 163, and then accurately control the outlet pressure. On the other hand, the pressure regulating spring 166 can share the pressure borne by the pressure regulating elastic member 163 to a certain extent, thereby avoiding the problem that when the inlet pressure is too high or the valve is frequently started and stopped, the pressure regulating elastic member 163 alone may be subjected to excessive deformation, fatigue failure, or even damage.

[0088] In addition, the combination of the pressure regulating spring 166 and the pressure regulating elastic member 163 can make the valve core assembly 162 respond to pressure changes more quickly. When the pressure changes, the elastic force of the pressure regulating spring 166 can cooperate with the deformation force of the pressure regulating elastic member 163 to accelerate the movement of the valve core assembly 162, that is, quickly adjust the throttling distance between the water port and the pressure regulating execution end, thereby improving the pressure regulating efficiency of the diverter 1.

[0089] For further details, please refer to Figures 4 to 6As shown, a pressure regulating limit platform 1194 is provided on the inner wall of the air cavity 1153 along the extension direction of the water injection conduit portion 1154. The extension length of the pressure regulating limit platform 1194 should be smaller than the extension length of the water injection conduit portion 1154. The end of the pressure regulating spring 166 is sleeved on the outside of the pressure regulating limit platform 1194 to achieve the purpose of limiting the pressure regulating spring 166 and improve the positioning accuracy and assembly efficiency of the pressure regulating spring 166 during the assembly process.

[0090] Preferably, please combine Figures 4 to 6 As shown, the valve core assembly 162 can abut against the pressure regulating limit platform 1194 along the central axis of the water injection conduit portion 1154, so that the pressure regulating execution end seals and closes the water passing port. That is, when the valve core assembly 162 moves along the central axis of the water injection conduit portion 1154 and toward the side close to the water passing port, when the valve core limit sleeve 1621 of the valve core assembly 162 abuts against the pressure regulating limit platform 1194, the plug elastic member 16232 of the valve core assembly 162 will also abut against the water passing port of the water injection conduit portion 1154, thereby increasing the bearing area and bearing capacity of the diverter 1.

[0091] Further, please refer to Figure 4 As shown, the valve housing 11 is also provided with a breathing hole 118, and the air cavity 1153 is connected to the outside of the valve housing 11 through the breathing hole 118, so that the pressure regulating assembly 16 can produce relative displacement along the central axis direction of the water injection conduit portion 1154. It can be understood that when the pressure regulating elastic member 163 and the pressure regulating spring 166 are deformed, the spatial pressure inside the air cavity 1153 will change. At this time, the air cavity 1153 is connected to the atmospheric pressure by using the breathing hole 118, which helps to maintain the pressure of the air cavity 1153 where the pressure regulating spring 166 is located stable, thereby avoiding the risk of excessive deformation and rupture caused by the pressure difference on both sides of the pressure regulating elastic member 163 exceeding the bearing capacity of the pressure regulating elastic member 163, thereby improving the service life of the pressure regulating assembly 16 and the diverter 1. In addition, the pressure in the air cavity 1153 is kept connected with the external environmental pressure through the breathing hole 118. In the process of reducing / regulating the pressure of tap water, it can effectively avoid the pressure dropping below the saturated vapor pressure of tap water to cause cavitation, thereby avoiding the vibration and noise of the diverter 1 due to the presence of bubbles.

[0092] Preferably, please refer to Figure 4As shown, the breathing hole 118 is provided on the valve body upper shell 116 of the valve shell 11, and the central axis of the breathing hole 118 is arranged parallel to the central axis of the water injection conduit portion 1154. With such an arrangement, from the perspective of stability, the consistent direction helps to maintain the equilibrium state of the air cavity 1153. During operation, when there is a slight fluctuation in pressure, the pressure regulating spring 166 will expand and contract according to the pressure change, and the position of the breathing hole 118 allows the gas to enter and exit in time, and cooperates with the action of the pressure regulating spring 166 and the pressure regulating elastic member 163 to quickly adjust the internal pressure. In terms of the accuracy of pressure regulation, when the breathing hole 118 and the pressure regulating spring 166 are in the same expansion and contraction direction, during the pressure change process, the path of the gas entering and exiting the breathing hole 118 is more matched and coordinated with the path of the internal space change caused by the expansion and contraction of the pressure regulating spring 166, which will be able to more accurately control the pressure reduction range.

[0093] Further, please refer to Figure 4 As shown, the breathing hole 118 is arranged on one side of the upper shell 116 of the valve body close to the edge, and the breathing hole 118 extends along the extension direction of the water injection conduit portion 1154 to the side of the upper shell 116 of the valve body close to the pressure regulating assembly 16, which will effectively ensure that the inner hole wall of the breathing hole 118 is more flat and smooth, so that the flow state of the gas passing through the breathing hole 118 is more stable, and the unstable phenomenon of local turbulence of the gas is effectively avoided, thereby ensuring that the air cavity 1153 can more accurately sense the change in pressure and more accurately adjust the pressure, thereby improving the accuracy of pressure regulation. Of course, the flat inner hole wall is not easy to accumulate impurities. In some working environments, the fluid may carry tiny particulate impurities, which are easy to gather at the protrusions, and may cause the breathing hole 118 to be blocked over time. The flat inner hole wall makes it difficult for impurities to adhere and accumulate, which can effectively ensure the smoothness of the breathing hole 118, ensure the normal breathing function of the air cavity 1153, and then ensure the stable operation of the entire diverter 1.

[0094] As a preferred method of this embodiment, please refer to Figure 7 and Figure 8As shown, a limit support column 1191 is provided on the valve body lower shell 117 of the valve housing 11, and the limit support column 1191 is preferably located directly below the valve disc plug 1623, and the limit support column 1191 is convexly arranged toward the liquid chamber 1611, and the pressure regulating execution end of the pressure regulating assembly 16 can abut against the limit support column 1191, so that the diverter 1 can limit the pressure regulating execution end of the valve core assembly 162 when it is not in use or when the outlet pressure drops, that is, the limit support column 1191 can support the valve core assembly 162. At this time, the throttling distance between the pressure regulating execution end and the water port of the water injection channel 1155 is the largest. Furthermore, an anti-sticking protrusion 1192 is provided at the end of the limit support column 1191 close to the pressure regulating execution end, so that a gap is formed between the limit support column 1191 and the pressure regulating execution end. This is equivalent to reducing the contact area between the limit support column 1191 and the pressure regulating execution end. It can also be understood that the pressure regulating execution end does not directly contact the end of the limit support column 1191. Therefore, when scale accumulation occurs at the end of the limit support column 1191, the pressure regulating execution end will not adhere to the limit support column 1191, thereby effectively preventing the diverter 1 from having a pressure regulating failure.

[0095] For further details, please refer to Figure 7 and Figure 8 As shown, the anti-sticking protrusion 1192 is distributed at the edge position of the end of the limiting support column 1191 and is extended along the circumference of the limiting support column 1191. The anti-sticking protrusion 1192 is preferably extended along the circumference of the limiting support column 1191 to form an arc-shaped structure. Then, tap water flowing through the limiting support column 1191 can clean the end of the limiting support column 1191 by itself, thereby reducing the probability of scale accumulation at the end of the limiting support column 1191.

[0096] It should be noted that the anti-sticking protrusion 1192 can also be set on the pressure regulating execution end, that is, the anti-sticking protrusion 1192 is set on the valve flap support 16231 of the valve flap plug 1623.

[0097] Preferably, a groove 1193 may be further provided at the end of the position-limiting support column 1191, and the anti-sticking protrusion 1192 is located on the side of the groove 1193. Such a configuration is equivalent to effectively increasing the gap distance between the position-limiting support column 1191 and the pressure-adjusting execution end, thereby further preventing the pressure-adjusting execution end from sticking to the position-limiting support column 1191, and improving the stability of the pressure adjustment of the diverter 1.

[0098] Furthermore, if Fig.16As shown, at least one conducting hole 16234 is provided on a side wall of the valve flap support 16231 close to the limiting support column 1191, which not only facilitates embedding the plug elastic member 16232 in the valve flap embedding groove 16233 of the valve flap support 16231 and pushing the plug elastic member 16232 out of the valve flap embedding groove 16233 of the valve flap support 16231, but also further reduces the contact area of ​​the pressure regulating execution end.

[0099] In the above, the water outlet chamber 1148 cooperates with the diversion component 17 to distribute the pure water purified by the water purifier 3, and the excess pure water inside the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diversion component 17 to form excess water, thereby effectively preventing the water pressure from fluctuating greatly during the sudden activation of the tankless pipeline machine 2 and / or the faucet 4, causing the water purifier 3 to start and stop frequently.

[0100] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail in conjunction with the drawings.

[0101] Please refer to Figure 4 As shown, the diverter 1 also includes a diverter assembly 17, on which a flow hole is provided, and the flow hole is used to guide the pure water flowing in from the pure water inlet 1143 to pass through the diverter assembly 17 and enter the water outlet chamber 1148. Further, the valve housing 11 has a reflux guide portion 1171, and the interior of the reflux guide portion 1171 is provided with a guide channel 1172 connected to the reflux chamber 1146, and the reflux guide portion 1171 extends toward the interior of the water outlet chamber 1148, and the reflux guide portion 1171 is preferably connected to the valve body lower shell 117. The diverter assembly 17 is installed in the water outlet chamber 1148 of the valve housing 11, and the diverter assembly 17 can abut against the reflux guide portion 1171. According to the pressure difference formed by the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145, the diverter component 17 can produce a relative displacement toward the first water supply port 1144, so that the diverter component 17 is separated from the reflux guide part 1171, and the excess pure water will be able to flow from the guide channel 1172 into the reflux chamber 1146 to form the above-mentioned excess water.

[0102] In this case, please combine Figure 7 and Figure 8 As shown, when the faucet 4 is used alone, pure water flows into the valve housing 11 from the pure water inlet 1143 and then flows out directly from the second water supply port 1145. At this time, the diversion component 17 abuts against the reflux guide portion 1171 to seal the guide channel 1172, and the pure water will not flow back to the guide channel 1172.

[0103] When the water tankless pipeline machine 2 uses water alone, pure water flows in from the pure water inlet 1143 and enters the water outlet chamber 1148 through the water hole, and finally flows out from the first water supply port 1144 to the water tankless pipeline machine 2. At this time, the pressure of the diverter component 17 on the side close to the first water supply port 1144 is less than the pressure on the side of the diverter component 17 facing away from the first water supply port 1144, that is, the water pressure formed by the pure water inlet 1143 and the second water supply port 1145 is greater than the water pressure on the side of the first water supply port 1144. The diverter component 17 can produce a relative displacement toward the side of the first water supply port 1144, so that the diverter component 17 is separated from the reflux guide portion 1171, and the excess pure water flows back to the guide channel 1172. When the water tankless pipeline machine 2 is turned off, the diverter component 17 will be reset toward the side of the reflux guide portion 1171, and the diverter component 17 will be re-contacted on the reflux guide portion 1171 to re-seal the guide channel 1172. Therefore, the diverter 1 can flexibly respond to the water flow distribution needs when the tankless pipeline machine 2 uses water alone, so that pure water can meet the water needs of the tankless pipeline machine 2 while reasonably processing excess water, without causing waste of water resources and avoiding the risk of damaging the tankless pipeline machine 2 due to excessive water pressure.

[0104] When the water tankless pipeline machine 2 and the faucet 4 use water at the same time, after the pure water inlet 1143 flows into the valve housing 11, a part of it flows out from the second water supply port 1145 to the faucet 4, and the other part passes through the water hole into the water outlet cavity 1148 and flows out from the first water supply port 1144 to the water tankless pipeline machine 2. Due to the reduction of the water pressure on the side of the second water supply port 1145, the pressure on the side of the diverter assembly 17 close to the first water supply port 1144 is not much different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144. At this time, the diverter assembly 17 abuts against the reflux guide 1171, and the excess pure water will not flow back to the guide channel 1172. In this way, the water tankless pipeline machine 2 and the faucet 4 can use water normally, and the stable operation of the entire drinking water purification system is guaranteed.

[0105] In this way, because when the tankless pipeline machine 2 is turned on, the excess pure water can flow back, so that the water purifier 3 can be prevented from frequently adjusting its own working state due to the sudden change in the water consumption of the tankless pipeline machine 2 (such as the change in water pressure caused by the frequent opening and closing of the tankless pipeline machine 2). For example, if there is no reflux mechanism, when the tankless pipeline machine 2 is suddenly closed, the instantaneous change in water pressure may have an impact on the internal structure and working pressure of the water purifier 3, and with the reflux mechanism, it can buffer this water pressure change to a certain extent and reduce the pressure of frequent start and stop of the water purifier 3. In the case of simultaneous water use, the relatively stable water flow distribution state is maintained by the action of the diverter component 17. If there is no diverter component 17, when the faucet 4 and the tankless pipeline machine 2 are working at the same time, the sudden change in water consumption of one party (such as the sudden closing of the faucet 4) may cause a large fluctuation in the internal water pressure of the water purifier 3, causing the water purifier 3 to frequently adjust its working state. The diverter component 17 can maintain a relatively stable water pressure and water flow distribution, reducing the frequent start and stop of the water purifier 3 caused by changes in external water use.

[0106] In some embodiments, please refer to Figure 4 As shown, the above-mentioned diverter assembly 17 includes a diverter balancing membrane 172 and a balancing spring 171. The diverter balancing membrane 172 is provided with a diaphragm through hole 1724. The flow-through hole includes the diaphragm through hole 1724. Since the diverter balancing membrane 172 is made of elastic material (such as silicone, rubber and other materials), the flow-through hole can be expanded and contracted under the action of its own rebound force. The balancing spring 171 is arranged between the diverter balancing membrane 172 and the inner cavity wall of the water outlet cavity 1148, and the edge of the diverter balancing membrane 172 is clamped between the valve body upper shell 116 and the valve body lower shell 117. In this way, when the water consumption of the water tankless pipeline machine 2 is large, the pressure on the side of the diverter balance membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144, and the effect of the pressure difference on the flow hole becomes larger, so that the amount of pure water flowing through the flow hole increases. When the water consumption of the water tankless pipeline machine 2 becomes smaller, the flow hole will shrink and become smaller by itself, and the amount of pure water flowing through the flow hole will decrease accordingly, so as to achieve the purpose of automatically maintaining the pressure difference on both sides of the diverter balance membrane 172 and delay the reset of the diverter balance membrane 172. At this time, there is no pure water flowing in the first water supply port 1144, and the diverter balance membrane 172 will reset under the action of the deformation recovery of the balance spring 171, thereby reducing the probability of frequent start and stop of the water purifier 3 when the water tankless pipeline machine 2 is low flow.

[0107] In this embodiment, please refer to Fig.17As shown, the shunt assembly 17 also includes a diaphragm top cover 173 and a diaphragm base 174, the diaphragm top cover 173 is provided with a top cover through hole 1731, the diaphragm base 174 is provided with a base through hole 1741, the shunt balancing membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, the diaphragm top cover 173 is preferably snap-connected with the diaphragm base 174, the top cover through hole 1731 and the base through hole 1741 are both connected to the diaphragm through hole 1724, at this time, the top cover through hole 1731, the base through hole 1741 and the diaphragm through hole 1724 form a flow hole, one end of the balance spring 171 abuts against the inner cavity wall of the water outlet cavity 1148, and the other end of the balance spring 171 abuts against the diaphragm top cover 173.

[0108] As a preferred method of this embodiment, please refer to Fig.17 As shown, the shunt balancing membrane 172 has a flexible check portion 1721 provided with a flow regulating port 1722. The flexible check portion 1721 is protruded toward one side of the diaphragm top cover 173 and penetrates the diaphragm top cover 173. According to the difference between the pressure on the side of the diaphragm top cover 173 and the pressure on the side of the diaphragm base 174, the flexible check portion 1721 can control the opening and closing size of the flow regulating port 1722 to adjust the amount of pure water flowing into the water outlet chamber 1148. The larger deformation of the flexible check portion 1721 compared to the flow hole is utilized, so that when the water consumption of the water tankless pipeline machine 2 is large, the pressure on the side of the shunt balancing membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the shunt component 17 facing away from the first water supply port 1144, so that more pure water can be supplied. The principle is the same as the above-mentioned elastically expandable flow hole. When the water consumption of the water tankless pipeline machine 2 decreases, the flexible check portion 1721 will shrink and become smaller by itself, and the amount of pure water flowing through the flexible check portion 1721 will decrease accordingly, thereby achieving the purpose of automatically maintaining the pressure difference on both sides of the diversion balance membrane 172, and can also reduce the probability of frequent start and stop of the water purifier 3.

[0109] It should be noted that the above-mentioned method of setting the elastically retractable flow hole and the method of setting the flexible check portion 1721 are selected to reduce the probability of frequent start and stop of the water purifier 3 when the water tankless pipeline machine 2 has a low flow rate. Of course, the two can also be used in combination.

[0110] In the above, the excess pure water in the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter assembly 17. The reflux chamber 1146 can merge the pressure-stabilized water after the pressure-stabilized pressure-regulating assembly 16 with the excess water returned by the diverter assembly 17, and output it from the raw water outlet 1142 to the water purifier 3, so that the water source can be redistributed and utilized inside the drinking water purification system, reducing the waste of water source. However, when the amount of excess water returned from the water outlet chamber 1148 toward the reflux chamber 1146 is much smaller than the amount of pressure-stabilized water transported from the water inlet chamber 1147 toward the reflux chamber 1146, that is, the pressure of the reflux chamber 1146 near the water outlet chamber 1148 is smaller than the pressure of the reflux chamber 1146 near the water inlet chamber 1147, which easily causes the pressure-stabilized water entering the reflux chamber 1146 to flow back into the water outlet chamber 1148, thereby affecting the water quality of domestic water and direct drinking water.

[0111] Based on this, an optimal method is also disclosed in the embodiments of the present application. Figure 4 As shown, the flow divider 1 also includes a one-way flow guide 13, which is arranged in the reflux chamber 1146 to prevent the pressure-stabilized water flowing through the water inlet chamber 1147 from flowing back to the water outlet chamber 1148 after being stabilized, and to output the excess water flowing back from the water outlet chamber 1148 to the reflux chamber 1146 to the water purifier 3 after merging with the pressure-stabilized water. This not only prevents the pressure-stabilized water from flowing back to the water outlet chamber 1148 after being stabilized in the water inlet chamber 1147, causing the purified water in the water outlet chamber 1148 to be mixed with the pressure-stabilized water, but also ensures the water quality and quantity of the purified water supplied by the flow divider 1. At the same time, the pressure of both the water outlet chamber 1148 and the water inlet chamber 1147 is maintained, so that the water source flow in the water outlet chamber 1148, the water inlet chamber 1147 and the reflux chamber 1146 can be carried out in the designed direction and pressure conditions, so as to simplify the pipeline components and connections of the drinking water purification system while ensuring its stability.

[0112] An unexpected effect is that the one-way flow guide 13 is assembled in the reflux chamber 1146 of the valve housing 11, making the assembly between the one-way flow guide 13 and the valve housing 11 more compact. In a drinking water purification system with limited space, such an assembly method has a higher degree of integration, saves space, and very effectively simplifies the pipeline layout of the drinking water purification system, and reduces the risk of leakage due to too many pipe connections. In addition, it can also prevent the diverter 1 and the drinking water purification system from being damaged by the water hammer phenomenon. It can be understood that when the pressure of the external water supply pipeline increases instantly, the inertia of the water flow will cause a water hammer effect, generating a very high pressure wave. At this time, the one-way flow guide 13 can prevent this high-pressure wave from reversely impacting the one-way flow guide 13, which is beneficial to extend the service life of the diverter 1 and reduce the maintenance cost of the diverter 1 and the drinking water purification system.

[0113] As a preferred method of this embodiment, please refer to Fig. 9 , Fig.10 and Fig.11 As shown, the above-mentioned one-way flow guide 13 includes a check body 131 and a mixed flow guide 132, wherein the check body 131 has an input port 1311 and an output port 1312, and the check body 131 is used to control the water source to flow from the input port 1311 to the output port 1312. It can be understood that the water source refers to the excess water that flows back from the water chamber 1148 toward the reflux chamber 1146. A flow guide channel 1321 is provided inside the mixing guide body 132. An extension portion 133 with a liquid injection port 1331 is provided on one side of the mixing guide body 132 protruding toward the check body 131. The extension portion 133 is extended along the circumferential portion of the mixing guide body 132 and is provided at the end of the mixing guide body 132. One end of the check body 131 provided with an output port 1312 abuts against the extension portion 133 to form a mixing chamber 1332. At this time, the opening formed by the mixing guide body 132, the extension portion 133 and the check body 131 is the liquid injection port 1331. The liquid injection port 1331 is connected to the mixing chamber 1332, and the output port 1312 is connected to the mixing chamber 1332. The input port 1311 is connected to the water outlet chamber 1148.

[0114] For further details, please refer to Figure 7 and Figure 8 As shown, the injection port 1331 of the one-way flow guide 13 is arranged toward the water inlet chamber 1147, that is, the injection port 1331 is aligned with the water inlet chamber 1147, and the injection port 1331 is connected to the water inlet chamber 1147, so the pressure-stabilized water flowing into the reflux chamber 1146 will flow into the mixing chamber 1332 through the injection port 1331. The input port 1311 of the check body 131 is connected to the water outlet chamber 1148, and the guide channel 1321 is connected to the raw water outlet 1142 of the valve body lower shell 117, so the excess water can only flow from the input port 1311 of the check body 131 and enter the mixing chamber 1332 through the output port 1312. At this time, the excess water is mixed with the pressure-stabilized water, and the excess water is guided to the raw water outlet 1142 by the guide channel 1321 after mixing with the pressure-stabilized water, and then transported to the water purifier 3. When the pressure in the mixing chamber 1332 is too high, that is, the pressure on the side of the reflux chamber 1146 close to the water outlet chamber 1148 is lower than the pressure on the side of the reflux chamber 1146 close to the water inlet chamber 1147, the check body 131 will close automatically under the action of the pressure, thereby preventing the stabilized pressure water from flowing back to the water outlet chamber 1148.

[0115] It should be supplemented that in order to ensure that the extension portion 133 can more stably abut against the end surface of the input port 1311 of the anti-return body 131, Figures 7 to 12As shown, the mixing flow guide 132 is provided with an auxiliary support portion 135 protruding toward one side of the check body 131. The auxiliary support portion 135 is preferably distributed opposite to the extension portion 133, and the length of the auxiliary support portion 135 is equal to the length of the extension portion 133. One end of the auxiliary support portion 135 away from the mixing flow guide 132 abuts against the check body 131. In this way, the auxiliary support portion 135 and the extension portion 133 are both abutted against the check body 131, which not only realizes a more balanced force between the mixing flow guide 132 and the check body 131, but also increases the contact area between the mixing flow guide 132 and the check body 131, thereby ensuring the compactness and stability of the overall structure of the one-way flow guide 13.

[0116] Preferably, please combine Figure 7 and Figure 8 As shown, a positioning protrusion 1322 is provided on the outer side wall of the extension portion 133 , and the extending direction of the positioning protrusion 1322 is consistent with the extending direction of the guide channel 1321 . The positioning protrusion 1322 is located at one side of the liquid injection port 1331 . A positioning groove 1149 is provided on the valve housing 11, and the positioning groove 1149 is located inside the reflux chamber 1146, and the positioning groove 1149 extends along the extension direction of the reflux chamber 1146. When the one-way flow guide 13 is assembled into the reflux chamber 1146, the positioning protrusion 1322 is inserted into the positioning groove 1149. Through the cooperation between the positioning protrusion 1322 and the positioning groove 1149, the injection port 1331 of the one-way flow guide 13 can align itself with the water inlet chamber 1147, that is, the pressure reduction chamber outlet 1151 is aligned with the injection port 1331, and the injection port 1331 fully covers the pressure reduction chamber outlet 1151, so that the pressure-stabilized water can flow more smoothly through the pressure reduction chamber outlet 1151 and the injection port 1331 and enter the mixing chamber 1332, thereby avoiding the problem of unstable water pressure caused by turbulence or eddy currents caused by the obstruction of the pressure-stabilized water.

[0117] In addition, during the process of assembling the one-way flow guide 13 into the reflux chamber 1146, it is only necessary to align the positioning protrusion 1322 of the one-way flow guide 13 with and slide it into the positioning groove 1149 inside the reflux chamber 1146, thereby improving the convenience and efficiency of assembling the one-way flow guide 13, facilitating the subsequent disassembly and maintenance of the one-way flow guide 13, improving the efficiency of repairing the diverter 1, and ensuring the stability of the diverter 1 during long-term use. Since the positioning protrusion 1322 is restricted by the positioning groove 1149, the one-way flow guide 13 is effectively prevented from being deflected and displaced in the reflux chamber 1146, thereby ensuring that the injection port 1331 of the one-way flow guide 13 is always aligned with the pressure relief chamber discharge port 1151 of the valve housing 11, thereby reducing the impact and vibration of the valve housing 11 by the pressure-stabilizing water, thereby reducing the noise of the diverter 1 during use.

[0118] For further details, please refer to Fig.10 and Fig.11As shown, one end of the mixing flow guide 132 close to the extension 133 is the shoulder end of the mixing flow guide 132, and the shoulder end and the extension 133 are offset to form a shoulder portion 134. It can be understood that the cross-sectional dimension of the shoulder end is greater than the cross-sectional dimension of the extension 133, and the shoulder portion 134 is the portion where the shoulder end and the extension 133 are connected and the cross-sectional dimension changes. Figure 8 As shown, a step limit portion 1152 is provided on the valve housing 11, and the step limit portion 1152 is located inside the reflux chamber 1146, that is, the inner wall of the channel of the reflux chamber 1146 protrudes toward the inside of the reflux chamber 1146 to form the step limit portion 1152, and the shoulder end of the one-way flow guide 13 abuts against the step limit portion 1152 of the valve housing 11, then the shoulder portion 134 of the one-way flow guide 13 can enable the mixed flow guide 132 to move horizontally in the extension direction of the positioning protrusion 1322.

[0119] In this embodiment, the mixed flow guide 132 of the one-way flow guide 13 is inserted into the interior of the reflux chamber 1146 under the guidance of the positioning groove 1149 until the shoulder portion 134 abuts against the step limit portion 1152 of the valve housing 11, thereby limiting the movement of the mixed flow guide 132 in the extension direction of the reflux chamber 1146, thereby achieving the purpose of efficient positioning.

[0120] Preferably, please combine Fig. 9 , Fig.10 and Fig.11 As shown, a drainage bottom slope 136 is provided between the inner wall of the mixing chamber 1332 and the inner wall of the guide channel 1321, and the drainage bottom slope 136 extends obliquely from the mixing chamber 1332 toward the inner wall of the flow channel of the guide channel 1321. Such a configuration can not only avoid the height difference in the process of the pressure-stabilized water flowing from the mixing chamber 1332 to the guide channel 1321, which causes a drastic change in a short time, generates a large impact force and the instability of local turbulence, but also ensures that the pressure-stabilized water is sequentially mixed in the mixing chamber 1332, the guide channel 1321, and is delivered from the raw water outlet 1142 to the water purifier 3 at a relatively stable speed and state.

[0121] As a preferred method of this embodiment, please refer to Fig. 9 and Fig.10 As shown, the check body 131 includes a fixed shell 1313 and a valve core body 1314, the valve core body 1314 is movably arranged inside the fixed shell 1313, the input port 1311 and the output port 1312 are both arranged on the fixed shell 1313, and the valve core body 1314 can open and close the input port 1311 according to the pressure difference between the input port 1311 and the output port 1312. It can be understood that the water pressure on the side of the input port 1311 is equivalent to the pressure on the side of the reflux chamber 1146 close to the water outlet chamber 1148, and the water pressure on the side of the output port 1312 is equivalent to the pressure on the side of the reflux chamber 1146 close to the water inlet chamber 1147.

[0122] When the water pressure on the side of the input port 1311 is greater than the water pressure on the side of the output port 1312, the valve core body 1314 can open the input port 1311, so that the excess water flowing back from the water outlet chamber 1148 toward the reflux chamber 1146 can enter the fixed shell 1313 through the input port 1311, and then enter the mixing chamber 1332 from the output port 1312 after passing through the fixed shell 1313. When the water pressure on the side of the input port 1311 is less than or equal to the water pressure on the side of the output port 1312, the valve core body 1314 will reset and close the input port 1311, so that the pressure-stabilized water entering the mixing chamber 1332 cannot flow through the fixed shell 1313 and then flow back to the water outlet chamber 1148, thereby achieving the purpose of unidirectional flow control of excess water.

[0123] Preferably, please combine Fig.11 and Fig.12 As shown, the valve core body 1314 includes a movable opening and closing part 13141 and an elastic reset part 13142, wherein the elastic reset part 13142 is preferably a spring. Of course, the elastic reset part 13142 can also be selected as a component made of elastic material (such as rubber material, silicone material, etc.). The elastic reset part 13142 is preferably sleeved on the movable opening and closing part 13141, and the two ends of the elastic reset part 13142 are respectively abutted against the movable opening and closing part 13141 and the fixed shell 1313. Specifically, a spring embedding groove is provided on the movable opening and closing part 13141, and the shape and size of the spring embedding groove are adapted to the shape and size of the elastic reset part 13142. The end of the elastic reset part 13142 is embedded in the spring embedding groove to prevent the elastic reset part 13142 from deflecting during the deformation process.

[0124] In this way, when the water pressure on the side of the input port 1311 is less than or equal to the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 abuts against the sealed input port 1311, effectively preventing the pressure-stabilized water from flowing through the input port 1311. When the water pressure on the side of the input port 1311 is greater than the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 moves away from the input port 1311 under the action of pressure, and at the same time squeezes the elastic reset part 13142 to generate deformation, so that the input port 1311 is connected to the output port 1312. At this time, excess water can enter the water outlet cavity 1148 through the input port 1311. It can be understood that when the water pressure on the side of the input port 1311 is again lower than the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 will reset toward the side of the input port 1311 under the action of the deformation recovery of the elastic reset part 13142, and the sealing head 13143 will automatically abut against the sealed input port 1311, preventing the pressure-stabilized water from flowing through the input port 1311 into the water outlet chamber 1148.

[0125] To ensure the sealing between the sealing head 13143 and the input port 1311, please refer to Fig.11 and Fig.12 As shown, a first sealing groove is provided on the sealing head 13143, and the first sealing groove extends along the circumference of the sealing head 13143, and a non-return sealing ring 13144 is embedded in the first sealing groove. Under the action of the non-return sealing ring 13144, the sealing performance between the sealing head 13143 and the input port 1311 can be effectively improved, and at the same time, the sealing head 13143 of the movable opening and closing part 13141 is ensured to be in flexible contact with the fixed shell 1313 during the opening and closing process, thereby reducing the wear of the non-return body 131 during the frequent opening and closing process, thereby effectively improving the service life of the non-return body 131 and the one-way fluid guide.

[0126] Preferably, please combine Fig.11 and Fig.12 As shown, the fixed shell 1313 includes a valve seat shell 13131 and a retaining inner frame 13132, the valve seat shell 13131 is sleeved on the outer side of the retaining inner frame 13132, the movable opening and closing part 13141 is inserted into the retaining inner frame 13132, the end of the elastic reset part 13142 abuts against the retaining inner frame 13132, the input port 1311 is arranged on the valve seat shell 13131, and the output port 1312 is arranged on the retaining inner frame 13132. When assembling the check body 131, first place the movable opening and closing part 13141 of the valve core body 1314 into the valve seat shell 13131, then sleeve the elastic reset part 13142 of the valve core body 1314 on the movable opening and closing part 13141, and finally embed the inner frame 13132 inside the valve seat shell 13131, and make the movable opening and closing part 13141 plugged into the inner frame 13132, so that the assembly of the check body 131 is completed. At this time, the sealing head 13143 of the movable opening and closing part 13141 abuts against the input port 1311 sealed on the valve seat shell 13131, and the elastic reset part 13142 is in a state of compression deformation. In this way, the valve seat shell 13131 and the inner frame 13132 can be produced separately, which reduces the difficulty of making the fixed shell 1313, thereby helping to reduce the manufacturing cost of the fixed shell 1313. At the same time, the assembly of the backstop 131 is facilitated, the assembly efficiency of the backstop 131 is improved, and the assembly cost of the backstop 131 is reduced.

[0127] Specifically, see Fig. 9, a holding arm 13134 is provided on the inner holding frame 13132, and the holding arm 13134 is located on the inner side of the output port 1312, that is, a holding arm 13134 is extended from the inner holding frame 13132 toward the inner side of the output port 1312, and a guide socket 13136 for plugging the movable opening and closing part 13141 is provided on the holding arm 13134, and the shape of the guide socket 13136 can be selected to match the shape of the end of the movable opening and closing part 13141, and of course, the shape of the guide socket 13136 can also be selected to match the shape of the movable opening and closing part The shapes of the ends of 13141 are different, but it is necessary to ensure that the side wall of the end of the movable opening and closing part 13141 abuts against the inner hole wall of the guide socket 13136, so that the movable opening and closing part 13141 can reciprocate along the central axis direction of the guide socket 13136, so that the guide socket 13136 cooperates with the elastic reset part 13142 to ensure that the sealing head 13143 of the movable opening and closing part 13141 is accurately reset and abutted on the input port 1311, and the end of the elastic reset part 13142 abuts against the retaining support arm 13134.

[0128] It should be noted here that Figures 9 to 12 As shown, the retaining arm 13134 is protruded toward the movable opening and closing part 13141 to provide a limiting boss 13135, and the guide plug hole 13136 passes through the limiting boss 13135, thereby increasing the contact area between the side wall of the end of the movable opening and closing part 13141 and the inner hole wall of the guide plug hole 13136. The end of the elastic reset part 13142 is sleeved on the limiting boss 13135, so that the limiting boss 13135 cooperates with the spring insertion groove provided on the movable opening and closing part 13141, which can not only ensure that the elastic reset part 13142 is firmly assembled in the fixed shell 1313, but also further prevent the elastic reset part 13142 from deflecting during the deformation process.

[0129] Further, please refer to Fig.11 As shown, in order to reduce the weight of the fixed shell 1313 and the check body 131, and also reduce the production materials of the fixed shell 1313, thereby reducing the production cost of the fixed shell 1313 and the check body 131, at least one material reduction opening 13133 is provided on the side wall of the inner frame 13132. The shape, size and number of the material reduction opening 13133 are not limited here. The shape, size and number of the material reduction opening 13133 can be set and adjusted according to the structural design and design requirements.

[0130] It should be noted that in order to ensure the sealing between the valve seat housing 13131 of the fixed housing 1313 and the inner wall of the reflux chamber 1146, please refer to the following for details. Figures 7 to 12As shown, a second sealing groove is provided on the valve seat shell 13131, and the second sealing groove extends along the circumference of the valve seat shell 13131. An outer sealing ring 137 is embedded in the second sealing groove. Under the action of the outer sealing ring 137, the sealing between the fixed shell 1313 of the check body 131 and the inner wall of the reflux chamber 1146 can be effectively improved.

[0131] It should be added here that in order to firmly install and fix the one-way flow guide 13 in the return chamber 1146 of the valve housing 11, please refer to Figure 7 and Figure 8 As shown, a pipe joint 14 is installed at the raw water outlet 1142 , and the one-way flow guide 13 is completely constrained in the reflux chamber 1146 by the pipe joint 14 , and a conduit can also be connected through the pipe joint 14 .

[0132] In addition, if Figure 4 , Figure 7 , Figure 8 As shown, at least one fastening seal ring 15 can be arranged between the pipe joint 14 and the one-way flow guide 13. On the one hand, the end of the conduit is penetrated by the fastening seal ring 15, which improves the sealing between the conduit and the reflux chamber 1146, effectively prevents the water-stabilizing water from leaking from the connection between the raw water outlet 1142 and the pipe joint 14, and also makes the conduit more firmly connected to the diverter 1. On the other hand, by utilizing the elasticity of the fastening seal ring 15, not only the pipe joint 14 and the one-way flow guide 13 are flexibly connected, but also when the pipe joint 14 is assembled to the raw water outlet 1142, the fastening seal ring 15 is elastically deformed under the extrusion of the pipe joint 14 and the one-way flow guide 13. This deformation enables the fastening seal ring 15 to fill the assembly gap between the pipe joint 14 and the one-way flow guide 13 by itself, and to adaptively change its own shape according to the size and shape of the assembly gap. At the same time, the elastic deformation also enables the fastening seal ring 15 to compensate for the gap change caused by factors such as expansion and vibration during the operation of the diverter 1 to a certain extent, thereby maintaining the stability of the assembly gap.

[0133] Of course, the pipe joint 14 can also be other quick joints or quick plug joints. Similarly, the pipe joint 14 and the above-mentioned fastening seal ring 15 are also adapted to be installed at the raw water inlet 1141, the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145. The size of the pipe joint 14 can be appropriately adjusted according to the raw water inlet 1141, the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145.

[0134] The present application also provides a water tankless pipeline machine 2, see Figures 18 to 20The tankless pipeline machine 2 includes a shell 21, a water system 22, an instant heating device 25 and a water outlet pipe 29. The shell 21 has a water inlet 211 and a water outlet 212, wherein the shell 21 may include a first shell and a second shell, wherein the first shell and the second shell may be detachably connected by snap connection, screw connection, etc. The first shell and the second shell enclose an installation cavity 215. The water system 22, the instant heating device 25 and the water outlet pipe 29 are all installed in the installation cavity 215. The water system 22 is used to supply water to the instant heating device 25, wherein the tankless pipeline machine 2 also includes an electronic control device 24, and the electronic control device 24 is used to control the working conditions of the water system 22 and the instant heating device 25. Through preset programs and algorithms, the electronic control device 24 can accurately adjust parameters such as water flow rate and water temperature to meet different needs of users.

[0135] It should be noted that the water inlet 211 and the water outlet 212 may be in the form of a pipe integrally formed on the housing 21, or may be in the form of a separate component, such as a hose or a joint. A avoidance opening is formed on the first shell and / or the second shell, and the components forming the water inlet 211 and / or the water outlet 212 may at least partially pass through the avoidance opening to extend into the installation cavity 215 and be connected to other components in the installation cavity 215.

[0136] See also Fig.19 and Fig. 20 In order to optimize the thermal management of the water tankless pipeline machine 2 and avoid unnecessary heat transfer and superposition between the electric control device 24 and the instant heating device 25, in some embodiments, the installation cavity 215 includes a strong current installation area 214 and a weak current installation area. In the length direction of the water tankless pipeline machine 2, the strong current installation area 214 and the weak current installation area are arranged at intervals, wherein the electric control device 24 is installed in the strong current installation area 214, and the instant heating device 25 is installed in the weak current installation area. Among them, the strong current installation area 214 is also the electric control installation area 213 for installing the electric control device 24. It can be understood that the instant heating device 25 needs strong power supply, and strong power has the characteristics of high voltage and large current; the electric control device 24 needs weak power supply, and weak power has the characteristics of low voltage and small current. Therefore, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged at intervals, so that electromagnetic interference can be reduced to ensure the stability and reliability of the electrical signal on the electric control device 24.

[0137] See also Fig.19 and Fig. 20Furthermore, the high-voltage installation area 214 includes a water channel installation area 2141 and an instant heating installation area 2142 which are arranged in sequence in the length direction. The electric control installation area 213 and the instant heating installation area 2142 are respectively located on both sides of the water channel installation area 2141. This can avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25. It can be understood that the instant heating device 25 requires high-voltage power supply, and high voltage has the characteristics of high voltage and large current; the electric control device 24 requires low-voltage power supply, and low voltage has the characteristics of low current. Therefore, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are spaced apart. In this way, electromagnetic interference can be reduced to ensure the stability and reliability of the electrical signal on the electric control device 24.

[0138] Since the water tankless pipeline machine 2 of the embodiment of the present application is designed without a water tank, it will not take up too much space. The overall size of the pipeline machine is smaller and can be installed in a smaller area, making the installation more flexible. Moreover, since the water tankless pipeline machine 2 does not need to store water, there is no need to maintain the water temperature in the water tank, which reduces energy consumption. It can also avoid problems such as dirt and grime easily accumulating inside the traditional water tank, severe odor, and bacterial growth, thereby ensuring the purity of the output water and improving the quality of drinking water.

[0139] See also Fig.19 and Fig. 20 as well as Fig. 22 , and because it is designed without a water tank, the water system 22 needs to be provided with a first water inlet solenoid valve 2211 and a pump assembly 2212. The first water inlet solenoid valve 2211 is responsible for controlling the on and off of the water flow, and the pump assembly 2212 is responsible for providing the power of the water flow. It is understandable that the first water inlet solenoid valve 2211 and the pump assembly 2212 are relatively large in size. In this application, the first water inlet solenoid valve 2211 and the pump assembly 2212 are arranged side by side in the length direction of the shell 21, while the volume of the water outlet pipe 29 is relatively small. In this application, the instant heating device 25 and the water outlet pipe 29 are arranged side by side in the thickness direction of the shell 21, and the first water inlet solenoid valve 2211 and the pump assembly 2212 are arranged in the waterway installation area 2141, and the instant heating device 25 and the water outlet pipe 29 are arranged in the instant heating installation area 2142. The installation layout provided in the present application can, firstly, space the water system 22 and the instant heating device 25 to avoid the heat generated by the instant heating device 25 affecting the operation of the water system 22; secondly, make the structure inside the entire shell 21 compact, save space, and be conducive to the miniaturization and lightweight of the equipment. For example, if the water outlet pipe 29 and the instant heating device 25 are arranged side by side in the length direction of the shell 21, it is easy to make the length of the shell 21 longer; thirdly, it can take into account the equipment repair or maintenance of the water system 22.

[0140] It should be noted that the first shell and the second shell of the present application are enclosed and fixedly connected in the horizontal direction, and after the first shell is disassembled, the equipment of the water 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. When installed and used, the second shell is hung on the wall. In this way, there is no need to remove the water tankless pipeline machine 2 as a whole, and the parts in the installation cavity 215 can be directly maintained or repaired after disassembling the first shell. Further explanation, based on the installation environment, the back of the water tankless pipeline machine 2 is attached to the wall, and the second shell can be in the form of a cover shell with an opening on the front side, and the first shell forms a cover structure and covers the opening.

[0141] In some embodiments, the pump assembly 2212 may include a flow control pump and a water pump. When the pump assembly 2212 includes a water pump, the water system 22 also includes a negative pressure valve 2217, which is arranged in the waterway installation area 2141. The negative pressure valve 2217 is connected to the first water inlet solenoid valve 2211 and the water pump, and is located between the first water inlet solenoid valve 2211 and the water pump. When the water flow in the waterway system 22 is cut off or the water pump stops working, the negative pressure valve 2217 can prevent the generation of negative pressure (i.e., pressure lower than atmospheric pressure) in the pipeline. Negative pressure may cause pipeline rupture, water hammer phenomenon (pressure shock caused by sudden cessation 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 and other components in the waterway system 22 from damage. There are many ways for the negative pressure valve 2217 to prevent the generation of negative pressure, such as air filling method, pre-pressure method, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in the relevant technology for a long time, and this application will not elaborate on it.

[0142] Of course, when the pump assembly 2212 is a flow control pump, the negative pressure valve 2217 may not be provided. A flow control pump is a pump that can maintain a constant pressure when the flow rate changes. The flow control pump can stabilize the fluid state in the delivery pipeline by accurately controlling the flow rate 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 rate to keep the fluid pressure in the pipeline within a stable range, thereby avoiding the occurrence of negative pressure.

[0143] See also Figure 19 to Figure 20In some embodiments, the water system 22 further includes a flow meter 2216, which is installed in the water installation area 2141, wherein the flow meter 2216 can be arranged between the water inlet 211 and the first water inlet solenoid valve 2211; or, between the first water inlet solenoid valve 2211 and the water pump; or, between the water pump and the instant heating device 25. The flow meter 2216 is used to measure the flow rate of water flow and provide accurate water use data for the user. By statistically analyzing the data collected by the flow meter 2216, the user can understand the water use pattern of the tankless pipeline machine 2.

[0144] See also Figure 19 to Figure 20 In some embodiments, the water system 22 further includes a water volume sensor 2215, which is installed in the water installation area 2141, and the water volume sensor 2215 can be arranged between the water inlet 211 and the first water inlet solenoid valve 2211; or, between the first water inlet solenoid valve 2211 and the water pump; or, between the water pump 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 volume sensor 2215 is lower than a preset value. The water volume sensor 2215 can monitor the water volume in the water system 22 in real time, and stop or reduce the power of the instant heating device 25 in time when the water volume is insufficient, so as to prevent the occurrence of dry burning and protect the safety of the equipment. By intelligently controlling the power of the instant heating device 25, the water volume sensor 2215 can achieve the effect of energy saving and power saving, and reduce the user's electricity cost.

[0145] See also Figure 19 to Figure 20 In some embodiments, in the direction of water flow, the first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are connected in sequence; wherein, the first water inlet solenoid valve 2211 and the negative pressure valve 2217 are arranged at intervals in the height direction of the housing 21, the water volume sensor 2215, the flow meter 2216 and the water pump are arranged at intervals in the height direction of the housing 21, and are located between the whole formed by the first water inlet solenoid valve 2211 and the negative pressure valve 2217 and the whole formed by the instant heating device 25 and the water outlet pipe 29, and the water pump is located below the water volume sensor 2215 and the flow meter 2216. The first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are partitioned according to their functions, so that the role of each component is clearer. When a fault occurs, the problem can be quickly located, which is convenient for maintenance and repair.

[0146] See also Fig.19 Fig.21In some embodiments, the housing 21 includes an outer shell 216 and a mounting frame 217, wherein the outer shell 216 includes the first shell and the second shell mentioned above, and has a mounting cavity 215; the mounting frame 217 is fixedly connected to the outer shell 216 and fixed in the mounting cavity 215, and the first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are all mounted on the mounting frame 217. In this way, each component can be installed on the mounting frame 217 first, and then the mounting frame 217 can be installed in the mounting cavity 215, making the assembly process simpler and faster, and reducing the difficulty and cost of installation. When a component fails or needs maintenance, the mounting frame 217 can be taken out as a whole, so that the water system 22 can be taken out to observe the location of the fault, which is convenient for replacing and maintaining components.

[0147] See also Fig. 22 In some embodiments, the tankless pipeline machine 2 further includes a sterilizing device 23, which is disposed on the outlet pipe 29 and sterilizes the water in the outlet pipe 29. The sterilizing device 23 may be an ultraviolet sterilizer or an ozone sterilizer, etc. Such a sterilizing device 23 can effectively sterilize without producing chemical residues, thereby reducing pollution to the environment. The sterilizing device 23 can effectively kill microorganisms such as bacteria and viruses in the outlet pipe 29, ensure the safety and sanitation of the water quality, and effectively reduce health problems caused by water quality problems.

[0148] See also Figure 20 to Figure 22 ,as well as Figure 8 In some embodiments, the water outlet 212 is arranged at the bottom of the housing 21; the water inlet end of the instant heating device 25 is located below the instant heating device 25, and the water outlet end is located above the instant heating device 25. Specifically, the water outlet 212 is located at the bottom of the housing 21, which is convenient for users to take water, especially for low spaces or children. The water inlet end and the water outlet end of the instant heating device 25 are located below and above it, respectively, which can improve the utilization rate of the space. In detail, since the water outlet 212 is located at the bottom of the housing 21, the water outlet of the water outlet pipe 29 is provided with a sterilization device 23, and considering the parallel arrangement of the water outlet pipe 29 and the instant heating device 25, the water inlet end of the water outlet pipe 29 is arranged above, so that the water inlet end and the water outlet end of the instant heating device 25 are located below and above it, respectively, so as to adapt to the arrangement direction of the water outlet pipe 29.

[0149] The arrangement of the above-mentioned water system 22 is also adapted to the direction of the water path in the instant heating installation area 2142. Specifically, the water inlet 211 is arranged at the bottom of the shell 21, and the first water inlet solenoid valve 2211 and the negative pressure valve 2217 are spaced apart in the height direction. The water volume sensor 2215, the flow meter 2216 and the water pump are also spaced apart in the height direction. After the water from the water source enters the water system 22 from the water inlet 211, it first passes through the first water inlet solenoid valve 2211 and the negative pressure valve 2217. At this time, the water flows upward, and then passes through the water volume sensor 2215, the flow meter 2216 and the water pump. At this time, the water flows downward, and then enters the instant heating device 25, flows upward again, and then flows downward through the water outlet pipe 29, and finally flows out from the water outlet 212.

[0150] In the present application, through reasonable layout of components, the space inside the shell 21 can be fully utilized, making the overall equipment more compact, the water flow can achieve smooth flow and efficient heating, and the components inside the equipment can be easy to maintain and repair, thereby improving the practicality of the water tankless pipeline machine 2.

[0151] In the present application, the first water inlet solenoid valve 2211, the flow control pump, the water volume sensor 2215 and the flow meter 2216 are all installed in the water channel installation area 2141, and the instant heating device 25 is installed in the instant heating installation area 2142, and in the length direction of the water tankless pipeline machine 2, the water channel installation area 2141 is located between the electric control installation area 213 and the instant heating installation area 2142; that is, in the length direction of the water tankless pipeline machine 2, the electric control device 24, the water channel system 22 and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the water channel system 22 to separate the electric control device 24 and the instant heating device 25, thereby reducing thermal energy interaction interference.

[0152] See also Fig. 22 In some embodiments, the water system 22 further includes a check valve 2218, which is disposed on the water outlet nozzle 212 and prevents water from flowing back in the pipe, thereby protecting other components in the water system 22, such as the water pump, the instant heating device 25, etc., from the impact and damage of the reverse water flow. When the water tankless pipeline machine 2 uses the instant heating device 25 to heat the water in the water system 22, since the instant heating device 25 heats rapidly, it is difficult for the instant heating device 25 to heat the water in the water system 22 to 100 degrees Celsius. Therefore, the check valve 2218 designed at the water outlet nozzle 212 in the embodiment of the present application can play a pressure-bearing role, so as to increase the boiling point of the water in the water outlet pipe 29, thereby making the water boil. In the process of water boiling, water vapor can be discharged from the water outlet pipe 29, and since the water outlet pipe 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge the water vapor, so that a stable water column can flow out of the water outlet nozzle 212.

[0153] See also Fig.19and Fig. 22 In some embodiments, the tankless pipeline machine 2 further includes an illumination lamp 28, which is disposed on the housing 21 and is disposed toward the water storage area of ​​the tankless pipeline machine 2, so that the light emitted by the illumination lamp 28 is irradiated on the water storage area, which is located below the water outlet 212. The illumination lamp 28 can illuminate the water storage area, so that the user can clearly see the water level, water quality, and whether there are impurities in the water container even in a dimly lit environment, thereby ensuring the accuracy and safety of water extraction. In addition, the illumination of the illumination lamp 28 helps the user to more intuitively check the cleanliness of the water storage area and the water outlet 212, thereby reminding the user to clean and maintain them in time to ensure water hygiene.

[0154] See also Fig.21 In some embodiments, the tankless pipeline machine 2 further includes a display device 27, which is disposed on the housing 21 to display the working information of the tankless pipeline machine 2. The display device 27 can display the working status of the tankless pipeline machine 2 in real time and intuitively, such as water temperature, working status (heating, water discharge, standby, etc.), and possible fault prompts, etc., so that users can better understand the working status of the equipment, thereby reasonably arranging the use time and frequency to avoid unnecessary energy waste. For example, when the water temperature is low, the required heating time is long, and the user can arrange other work first, avoiding wasting time waiting for the water temperature to rise.

[0155] In some embodiments, the display device 27 and the irradiation lamp 28 are both installed in the instant hot installation area 2142, so that the display device 27 and the irradiation lamp 28 can be close to each other. Since the display device 27 and the irradiation lamp 28 are close to each other, in the embodiment of the present application, the display device 27 and the irradiation lamp 28 are electrically connected, and the display device 27 is also used to power the irradiation lamp 28 and directly control the opening and closing of the irradiation lamp 28, which helps to simplify the wiring complexity in the tankless pipeline machine 2.

[0156] Please return to Figure 1 The fresh mineral water path 5 is connected to the external fresh mineral water source and the water outlet pipe 29, and the external fresh mineral water can flow to the water outlet 212 through the fresh mineral water path 5 and the water outlet pipe 29 without being heated by the instant heating device 25. The fresh mineral water path 5 is provided with a third water inlet solenoid valve 51, and the third water inlet solenoid valve 51 is used to control the opening and closing of the fresh mineral water path 5.

[0157] Furthermore, fresh mineral water can be provided by a water purifier 3 , which is provided with a fresh mineral water module to convert incoming tap water into fresh mineral water. The water purifier 3 is provided with a fresh mineral water outlet 33 , which is connected to a fresh mineral water waterway 5 to provide fresh mineral water to the water tankless pipeline machine 2 .
