[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0019] ​It should be understood that although the terms upper, middle, lower, top end, one end, etc. appear herein to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for the purpose of understanding, but are not used to define any restriction in direction or sequence.

[0020] As shown in Figures 1-14 A waterway system of a docking water outlet device, comprising: A water outlet shell 1, the water outlet shell 1 is arranged in a transverse direction, and a water inlet 2 is arranged in the middle of the water outlet shell 1, the water inlet 2 is used to engage with a port of a faucet 14, so as to fix the water outlet shell 1 on the faucet 14; A water inlet channel 7 and a heating cavity 4 are arranged in the water outlet shell 1 and extend in a transverse direction, the extending direction of the water inlet channel 7 and the heating cavity 4 is consistent with the extending direction of the water outlet shell 1, and the water inlet channel 7 and the heating cavity 4 are arranged in a vertical direction and are spaced apart, so as to divide the water outlet shell 1 in the vertical direction, the heating cavity 4 is provided with a heating module 5, the heating module 5 preferably also extends along the extending direction of the water outlet shell 1 and the heating cavity 4, and the water outlet shell 1 is further provided with a water outlet 3 which is connected to the heating cavity 4; A control valve 6, the water control assembly and the heating cavity 4 are connected to the water inlet 2 through the control valve 6, wherein the control valve 6 is a conventional control valve 6 in the prior art, according to the type of the control valve 6, the water outlet mode is operated by rotation or other operation mode, according to the operating position of the control valve 6, it includes but is not limited to hot water outlet mode, cold water outlet mode, and the intermediate position of disconnecting the faucet 14 and the docking water outlet device; The water control assembly, when the control valve 6 is selected as the hot water outlet mode, the water control assembly receives the water flow and connects the water inlet channel 7 and the heating cavity 4 in the vertical direction, the water control assembly receives the water inlet pressure and triggers the water inlet signal to turn on the heating module 5, at this time the heating module 5 works to heat the water flow in the heating cavity 4; As shown in Figures 2 to 4 In this embodiment, the control valve 6 and the water control assembly are arranged on the water outlet shell 1, the water inlet 2 is located between the control valve 6 and the water control assembly, and the control valve 6 and the water control assembly are preferably arranged at both ends of the water outlet shell 1, the water outlet shell 1, the control valve 6, the water control assembly and the heating cavity 4 are all arranged in a transverse direction, forming a compact "one" type structure. This layout greatly reduces the center of gravity of the entire device and makes it close to the port of the faucet 14, i.e. the water inlet 2 of the water outlet shell 1, effectively eliminating the large torque generated by the vertical suspension of the electric heating module in the prior art, which not only solves the problem of "head heavy feet light", makes the installation more stable, greatly reduces the stress on the faucet 14 body and the docking interface, fundamentally avoids the risk of sealing failure and water leakage caused by long-term stress, prolongs the service life of the product and the faucet 14, and is safer.

[0021] Further referring to Figure 11and Figure 12 As shown, it is worth mentioning that the water inlet channel 7 and the heating chamber 4 are arranged vertically at intervals and horizontally extended. This design creates a nearly straight and smooth "U" or "U" shaped flow channel. The water flows from the upper water inlet 2 into the horizontal water inlet channel 7, then into the water control component to the lower heating chamber 4. Subsequently, the water flows horizontally within the heating chamber 4 for heating, and then is output from the water outlet 3. The change in water flow direction is gradual, and the flow resistance is significantly reduced.

[0022] As a further explanation of the water inlet channel 7, the water inlet channel 7 includes a cold water inlet channel 7.1 and a hot water inlet channel 7.2. The cold water inlet channel 7.1 refers to the channel at the front end of the control valve 6 and connected to the faucet port 14, which is used to introduce cold water. The hot water inlet channel 7.2 refers to the channel located at the rear end of the control valve 6. The control valve 6 is adjusted to the hot water outlet mode, thereby controlling the connection between the cold water inlet channel 7.1 and the hot water inlet channel 7.2. In this embodiment, the extension direction of the cold water inlet channel 7.1 is not limited. Of course, the cold water inlet channel 7.1 is preferably extended laterally along the outlet shell 1. On the one hand, it is more conducive to the control of the overall center of gravity of the outlet shell 1. On the other hand, this arrangement is more conducive to the forming of the outlet shell 1 and the arrangement of the hot water inlet channel 7.2.

[0023] Specifically, the cold water inlet channel 7.1 is connected to the water inlet 2, the hot water inlet channel 7.2 is connected to the cold water inlet channel 7.1 through the control valve 6, and the hot water inlet channel 7.2 is connected to the heating chamber 4 through the water control component.

[0024] In addition, the outlet housing 1 is also equipped with a cold water outlet channel 15. At this time, the control valve 6 is adjusted to the cold water outlet mode, and the cold water inlet channel 7.1 is connected to the cold water outlet channel 15. The cold water outlet channel 15 is arranged adjacent to the hot water inlet channel 7.2 so that the water flow can be led out through the control valve 6.

[0025] Preferably, the cold water outlet channel 15 does not need to be set with a separate cavity. The cold water outlet channel 15 is opened on the side wall adjacent to the control valve 6 in the water outlet housing 1. The cold water outlet channel 15 can be a hole set on the side wall. The cold water outlet channel 15 is connected to the heating chamber 4. At this time, since there is no water flow in the hot water inlet channel 7.2, the water control component and the heating module 5 are disconnected, and the cold water flow is directly output from the outlet 3 in the heating chamber 4.

[0026] As a further improvement to the inlet channel 7, the outlet housing 1 includes at least a top wall 1.5 and a bottom wall 1.6. The inlet 2 is arranged on the top wall 1.5, and the outlet 3 is arranged on the bottom wall 1.6. The cold water inlet channel 7.1 and / or the hot water inlet channel 7.2 are integrally formed on the top wall 1.5 of the outlet housing 1. The cold water outlet channel 15 can be arranged on the side wall of the outlet housing 1 corresponding to the control valve 6. Depending on the position of the control valve 6, the cold water outlet channel 15 can also be arranged on the top wall 1.5. Preferably, the cold water outlet channel 15 is located between the cold water inlet channel 7.1 and the hot water inlet channel 7.2, thereby making full use of the space of the top wall 1.5 of the outlet housing 1. The cold water outlet channel 15, the cold water inlet channel 7.1, and the hot water inlet channel 7.2 are arranged side by side.

[0027] Both the cold water inlet channel 7.1 and the hot water inlet channel 7.2 are U-shaped partitions 1.3 formed at the bottom of the top wall 1.5, defining the heating chamber 4 below the inlet channel 7. The U-shaped partitions 1.3 extend laterally from the wall where the control valve 6 is located. The cold water inlet channel 7.1 is separated from the control valve 6 at one end on the outlet housing 1, while the hot water inlet channel 7.2 is connected to the water control component at the other end on the outlet housing 1. Through these improvements, the integrally formed hot water inlet channel 7.2 and cold water inlet channel 7.1 form a clear water flow path inside the outlet housing 1, while ensuring the structural strength and water tightness of the hot water inlet channel 7.2 and cold water inlet channel 7.1. The internal water flow switching is achieved through the control valve 6, and there is only one mixed water outlet 3 on the outside, making the user experience simpler and avoiding the confusion and splashing problems caused by two water outlets 3.

[0028] It should be noted that the water control component is connected to the hot water inlet channel 7.2 via a movable valve diaphragm 8.2. In the cold water outlet mode, there is no water flow in the hot water inlet channel 7.2, and the water control component closes the hot water inlet channel 7.2. In the hot water outlet mode, the water flow impacts the valve diaphragm 8.2, forcing the valve diaphragm 8.2 to open, thereby connecting the hot water inlet channel 7.2 and the heating chamber 4.

[0029] like Figure 7 and Figure 8 As shown, as a further embodiment of the water control component, the water control component includes a water pressure switch 8 connected to the end of the hot water inlet channel 7.2. The water pressure switch 8 includes a conductive sheet group 8.1 connected to the heating module 5 and a valve diaphragm 8.2. The water pressure switch 8 determines that the current mode is hot water. At this time, the incoming water flows through the hot water inlet channel 7.2 and acts on the valve diaphragm 8.2 to conduct the conductive sheet group 8.1.

[0030] Specifically, the valve diaphragm 8.2 includes a control unit 8.22 that cooperates with the conductive sheet group 8.1 and controls the conductive sheet group 8.1 to be turned on or off, and a water-facing surface 8.21 facing the water inlet and outlet direction. The conductive sheet group 8.1 includes a fixed conductive sheet 8.12 and a movable conductive sheet 8.11. The movable conductive sheet 8.11 is connected to the heating module 5. The control unit 8.22 is slidably disposed in the water pressure switch 8 and is positioned directly opposite the movable conductive sheet 8.11. Further reference Figure 13 and Figure 14 As shown, the outlet housing 1 is also provided with a water passage 9 that connects the heating chamber 4 and the water-facing surface 8.21. Under normal conditions, the valve diaphragm 8.2 is closed in the water passage 9 to maintain normal isolation. The valve diaphragm 8.2 receives the incoming water flow through the water-facing surface 8.21 and deforms. Under the deformed posture, the valve diaphragm 8.2 releases a gap for the incoming water flow to enter the water passage 9. At the same time, the control unit 8.22 moves towards the movable conductive plate 8.11 under the deformation action, and drives the movable conductive plate 8.11 to engage with the fixed conductive plate 8.12, so as to realize the conduction of the heating module 5.

[0031] The valve diaphragm 8.2 can be reset by the reset action of the movable conductive sheet 8.11 itself, or by setting an elastic element in the water pressure switch 8 to abut against the valve diaphragm 8.2, so as to provide a reset force for the valve diaphragm 8.2 toward the water passage 9.

[0032] from Figure 8 As can be seen, as a further improvement to the water control component, a one-way valve 10 is provided between the water inlet channel 7 and the heating chamber 4. The one-way valve 10 is located on the water inlet side or the water outlet side of the water control component. The function of the one-way valve 10 is to prevent water backflow. Therefore, the position of the one-way valve 10 relative to the water control component is not limited.

[0033] In another embodiment, the check valve 10 is disposed in the water passage 9, that is, on the outlet side of the water control component. The check valve 10 is preferably disposed in the vertical part of the water passage 9, thereby providing an installation position for the check valve 10 in the compact horizontal water path, providing a stable pressure environment for the water pressure switch 8, ensuring that its switching signal is accurate, avoiding misleading opening or disconnection caused by water flow fluctuations, and further enhancing the reliability of safety protection.

[0034] As a further improvement to the water passage 9, the transverse water inlet channel 7 and heating chamber 4, as well as the vertical water passage 9 connecting the hot water inlet channel 7.2 and heating chamber 4, benefit from the structural layout of the transverse water passage shell. The end of the outlet shell 1 is provided with a control shell 1.1 spaced apart from the heating chamber 4. The water passage 9 is disposed on the control shell 1.1. The control shell 1.1 includes a diaphragm seat 1.2 for fixing the valve diaphragm 8.2. The diaphragm seat 1.2 is connected to the hot water inlet channel 7.2 so that the incoming water flow can act on the valve diaphragm 8.2. The diaphragm seat 1.2 is provided with a water passage 9 connected to the water passage 9. The water inlet 9.1 can be part of the water passage 9. The water inlet 9.1 is adapted to the arrangement direction of the water pressure switch 8. In this embodiment, the water pressure switch 8 is arranged laterally along the extension direction of the water outlet housing 1. The water inlet 9.1 is flush with the top of the water passage 9. At this time, the valve diaphragm 8.2 is fixed in a vertical position. The diaphragm seat 1.2 is also used to provide an installation position for the water pressure switch 8. The water pressure switch 8 is fixed laterally on the diaphragm seat 1.2. Through the above improvements, the space between the laterally extending water inlet channel 7 and the end of the heating chamber 4 is fully utilized.

[0035] If space permits, the one-way valve 10 can also be installed in the water inlet 9.1.

[0036] like Figure 4 As shown, specifically, a first fixing space is provided between the membrane seat 1.2 and the bottom of the water outlet housing 1 for connecting the first end 5.1 of the heating module 5. A valve seat 1.4 is provided at the end of the water outlet housing 1 away from the control housing 1.1 for accommodating and fixing the control valve 6. The valve seat 1.4 is preferably set at the same height as the control housing 1.1. A second fixing space is provided between the bottom walls 1.6 of the water outlet housing 1 for connecting the second end 5.2 of the heating module 5. Both ends of the heating module 5 are provided with a first sealing ring 5.3, which abuts against the walls of the first fixing space and the second fixing space, respectively.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, in some other embodiments, the control housing 1.1 is also provided with a temperature control component 11. The temperature control component 11 includes a mounting base 11.1 and a temperature control switch 11.2 disposed on the mounting base 11.1. The temperature sensing part of the temperature control switch 11.2 extends into the heating chamber 4. The upper part of the water passage 9 is open, and the end of the mounting base 11.1 extends and seals the opening of the water passage 9. A second sealing ring 11.4 is provided on the extended end 11.3 of the mounting base. The second sealing ring 11.4 abuts between the extended end 11.3 and the top of the water passage 9, and the one-way valve 10 abuts against the extended end 11.3. The mounting base 11.1 is used to seal the water passage 9, which serves two purposes, reduces the need for separate seals and assembly steps, and improves production efficiency and sealing reliability.

[0038] In the above embodiment, the water control components and thermostat are centrally arranged at the other end, with clear functional zoning, which facilitates installation and maintenance.

[0039] The top of the control housing 1.1 is also equipped with a circuit board 13, which is connected to the water pressure switch 8 and the heating module 5.

[0040] like Figure 9 As shown, specifically, the outlet 3 is provided with an outlet pipe 3.1 connected to the heating chamber 4. The outlet pipe 3.1 extends toward the top of the outlet housing 1, and the top of the outlet pipe 3.1 is set higher than the heating module 5. The heating module 5 extends laterally in the heating chamber 4 along the direction of the outlet housing 1, so that the incoming water flow first fills the horizontal heating chamber 4 and fully contacts the heating module 5. After reaching the top height of the outlet pipe 3.1, it is output from the outlet pipe 3.1. At this time, the one-way valve 10 prevents the hot water in the heating chamber 4 from flowing back to the water passage 9 and the water pressure switch 8.

[0041] In addition, this ensures that even after the water outlet is turned off, some water can remain in the heating chamber 4, preventing the heating chamber 4 from being emptied and avoiding the situation where the heating tube is started and burned dry when there is no water.

[0042] As a further embodiment of the heating module 5, the heating module 5 is preferably a heating tube assembly, including at least one heating tube. The heating tube extends laterally along the heating cavity 4 and is disposed at both ends of the water outlet shell 1, so that the heating module 5 is parallel to the water flow direction. The water flow can evenly wrap around and flow over the entire surface of the heating tube, resulting in a large heating area without dead corners, high heating efficiency and uniformity, avoiding local overheating and extending the life of the heating tube.

[0043] As a further constraint on the overall layout of the outlet shell 1, the inlet 2 and outlet 3 are vertically opposite each other on the outlet shell 1. Combined with the transverse flow channel, the water flow path is natural and smooth. Together, they form a water system with low flow resistance, high flow rate, and sufficient and uniform heating.

[0044] Preferably, the inlet 2 and outlet 3 are located in the middle of the outlet housing 1. The control valve 6 is located at one end of the outlet housing 1, and the water control assembly is located at the other end of the outlet housing 1. The main weight components, including the control valve 6 (containing a metal valve core and handle) and the metal or plastic module water control assembly (containing a water pressure switch 8), are arranged at both ends of the transverse housing. The heating module 5 is arranged along the transverse direction of the outlet housing 1. Arranging the pipe interfaces of the inlet 2 and outlet 3 in the middle of the housing is beneficial for controlling the mass distribution of the entire device and improving installation stability. After long-term use, when the user rotates the handle of the control valve 6, the entire device will not feel loose or twisted.

[0045] In this embodiment, the water pressure switch 8 and the control valve 6 are preferably arranged in a direction parallel to the lateral extension of the water outlet housing 1. In the above embodiment, the control valve 6 and the water control component are set in a direction parallel to the water outlet housing 1, that is, the control valve 6 and the water control component are located on the left and right sides of the faucet 14, and the water outlet housing 1 extends on the left and right sides of the faucet 14. Combined with the arrangement of the inlet 2 and the outlet 3, the entire water outlet housing 1 forms a cross-shaped structure, which further improves the structural stability and weight balance.

[0046] Of course, in some cases, the orientation of the water pressure switch 8 and the control valve 6 can be modified. For example, the control valve 6 can be vertically positioned at the end of the outlet housing 1, or on the top wall 1.5 at the end of the outlet housing 1.

[0047] In some embodiments, the control valve 6 and the water control assembly may be arranged perpendicular to the direction of the water outlet housing 1, that is, the control valve 6 and the water control assembly are located on the front and rear sides of the faucet 14, and the water outlet housing 1 extends on the left and right sides of the faucet 14.

[0048] like Figure 1 and Figure 2 As shown, specifically, the inlet 2 is provided with a connecting component 12 for engaging with the faucet 14. The connecting component 12 is a conventional faucet 14 fixing solution from the market, including a threaded sleeve 12.1 and a threaded seat 12.2 disposed on the periphery of the inlet 2 of the outlet housing 1. The threaded sleeve 12.1 is used to engage with the port of the faucet 14 and is fixedly connected with the threaded seat 12.2, thereby connecting the water outlet device to the faucet 14. Further details are omitted here.

[0049] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
