[0002] Currently, with the improvement of people's living standards, plug-in electric water faucets are becoming increasingly popular in the market due to their installation-free and easy-to-use features.

[0003] This type of electric water faucet is installed at the water outlet of a water tap and includes a control valve assembly and an electric heating head assembly. In the prior art, an electric water faucet typically has a vertical heating chamber on one side connected to the water inlet, with a spiral heating tube inside the heating chamber, and a user-operable control valve on the other side connected to the water inlet to control the cold water or hot water working mode. However, the spatial planning of the electrical control components of this type of electric water faucet is unreasonable, resulting in a large vertical space occupation and making it difficult to adapt to the application of linear tubular heating tube assemblies.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document 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 ease of understanding, and are not used to define any directional or sequential restrictions.

[0020] like Figure 1-16 As shown, An electrically controlled connection structure for an electrically heated water outlet includes: The water outlet housing 1 is horizontally arranged, specifically horizontally arranged in the horizontal direction. The water outlet housing 1 is used to connect to the faucet 15. The water outlet housing 1 is provided with an inlet 1.1 and an outlet 1.2. The inlet 1.1 is connected to the faucet 15, and the water outlet housing 1 is provided with a heating chamber 1.3. The heating chamber 1.3 is provided with a heating tube assembly 2. The heating chamber 1.3 and the heating tube assembly 2 extend along the length direction of the water outlet housing 1. The heating chamber 1.3 is connected to the outlet 1.2. The outlet 1.2 is preferably located at the bottom of the water outlet housing 1, and the inlet 1.1 is preferably located at the top of the water outlet housing 1.

The electrical control installation area includes a first area 3 arranged on the upper surface of the water outlet housing 1 corresponding to the heating chamber 1.3, and a second area 4 arranged on the end of the water outlet housing 1 corresponding to the heating chamber 1.3. Both the first area 3 and the second area 4 define a recessed assembly space on the surface of the water outlet housing 1, and the first area 3 and the second area 4 are arranged perpendicularly and communicate with each other. A circuit board 5 is provided on the first region 3. The circuit board 5 is preferably consistent with the outline of the first region 3 so that the electronic control components on the circuit board 5 can be evenly arranged. A water pressure switch 6 is provided on the second area 4. The water pressure switch 6 is fixed on the second area 4 in a vertical position. The live wire end 2.1 of the heating tube assembly 2 extends out of the second area 4 and is connected to the water pressure switch 6. The water pressure switch 6 is connected to the circuit board 5. Preferably, the heating tube assembly 2 is linearly arranged and extends out of the bottom of the second area 4 to ensure that the water flow is fully heated in the heating chamber 1.3. The circuit board 5 extends from the first area 3 to the second area 4 to facilitate connection with the water pressure switch 6. Further reference Figure 2 As shown, the outlet housing 1 is also provided with a neutral wire channel 1.4 extending along its length. The neutral wire channel 1.4 runs through the end of the outlet housing 1 away from the second region 4 and the first region 3. The neutral wire channel 1.4 is used to pass through the neutral wire for connection of the heating tube assembly 2.

[0021] like Figure 6As shown, specifically, the outlet housing 1 is provided with a third region 1.63 for the other end of the heating tube assembly 2 to extend out. The third region 1.63 is located at the end of the outlet housing 1 away from the electrical control installation area from the inlet 1.1. That is, the third region 1.63 and the second region 4 are located at opposite ends of the outlet housing 1 along its length. The neutral wire end 2.2 of the heating tube assembly 2 extends out of the third region 1.63. The neutral wire channel 1.4 connects the first region 3 and the third region 1.63. Specifically, the neutral wire channel 1.4 connects the neutral wire end 2.2 of the heating tube assembly 2 and the first region 3. Thus, the third region 1.63 forms a concave cavity at the other end of the outlet housing 1 for wiring operations. Furthermore, the first region 3 and the second region 4 are located on the same side of the inlet 1.1 on the outlet housing 1. The live wire end 2.1 and the neutral wire end 2.2 of the heating tube assembly 2 are respectively led to the electrical control installation area through the neutral wire channel 1.4, realizing centralized management of the connection of all electrical control components. Reference Figure 5 As shown, as a further explanation of the first region 3, the first region 3 is recessed on the surface of the water outlet housing 1. Specifically, the first region 3 includes a first part 3.1 and a second part 3.2 spaced apart in the front-rear direction of the water outlet housing 1. The first part 3.1 is further recessed relative to the second part 3.2. The second part 3.2 forms a support wall on the surface of the water outlet housing 1. The neutral wire channel 1.4 is integrally formed on the side of the water outlet housing 1, and one side opening of the neutral wire channel 1.4 is located in the first part 3.1, and the other side opening of the neutral wire channel 1.4 is located in the third region 1.63 to facilitate the neutral wire wiring operation.

[0022] Specifically, the circuit board 5 supports and shields the first area 3, and the circuit board 5 is provided with a clearance opening 5.1 for the power control components to extend from the first area 3. The circuit board 5 serves as a shield for the power control installation area, which simplifies the structural design of the water outlet housing 1. The clearance opening 5.1 allows the power control components to pass through and be shielded on the circuit board 5, thereby further compressing the space and achieving a compact layout.

[0023] Specifically, the first region 3 and the second region 4 are open on the surface of the water outlet shell 1, and a protective cover 10 is also provided on the outside of the first region 3 and the second region 4. The protective cover 10 and the water outlet shell 1 define a power inlet 11 in the second region 4. The open first region 3 and the second region 4 form an open space, thereby releasing the operation and assembly space of the electronic control components. Finally, the protective cover 10 is used to enclose the power inlet 11, and together with the shell, they form a regular power inlet 11. In addition, an end cap 14 is arranged in the third region 1.63 to close and protect the neutral wire end 2.2 of the heating tube assembly 2.

[0024] Reference Figure 16As shown, to ensure protection of the open first region 3 and the second region 4, in this embodiment, a surrounding wall 3.3 is provided on the contour side of the first region 3. The outer contour of the circuit board 5 matches the inner contour of the surrounding wall 3.3. The protective cover 10 has an L-shaped structure. A fastening groove 3.4 is provided at the end of the surrounding wall 3.3 away from the second region 4, and a fastening block 10.1 matching the fastening groove 3.4 is provided at the end of the protective cover 10. Figure 16 (The dotted line portion) The protective cover 10 surrounds the outer side of the enclosure wall 3.3. The protective cover 10 is provided with a fixing seat corresponding to the second region 4. The fixing seat is connected to the second region 4 along the length direction of the water outlet shell 1. A bolt connection part and a wire harness snap-fit ​​part 10.2 are provided on the fixing seat. A wire harness mating part matching the wire harness snap-fit ​​part 10.2 is provided on the side of the second region 4. Through the above improvements, during the assembly process, thanks to the L-shaped shape of the protective cover 10, after the fixing seat is inserted into the second region 4, the end of the protective cover 10 where the buckle 10.1 is located can be deformed and snap into the enclosure wall 3.3. In the assembled state, the protective cover 10 and the enclosure wall 3.3 are engaged by a snap-fit ​​structure, and the protective cover 10 stops the enclosure wall 3.3 in the length direction of the water outlet shell 1. In the height direction, the protective cover 10 is fixed to the water outlet shell 1 by the fixing seat and is restricted from falling out, thereby ensuring the structural stability of the protective cover 10 on the water outlet shell 1.

[0025] like Figure 5 As shown, in this embodiment, a temperature control switch 7 is provided in the first region 3. The temperature control switch 7 is specifically located in the first part 3.1. The circuit board 5 is pressed on the top of the temperature control switch 7. The temperature control switch 7 is connected to the circuit board 5, and the temperature control switch 7 extends at least partially into the heating chamber 1.3, or the temperature control switch 7 abuts against the heating tube assembly 2.

[0026] The temperature control switch 7 includes a temperature control base 7.1 and a temperature control body 7.2. The temperature control body 7.2 passes through the bottom wall of the first part 3.1 so that the temperature sensing part of the temperature control body 7.2 enters the heating chamber 1.3. The temperature control body 7.2 and the bottom wall of the first part 3.1 are sealed by a sealing ring. The temperature control base 7.1 is pressed onto the temperature control body 7.2 and fixed inside the first part 3.1. The circuit board 5 is pressed onto the temperature control base 7.1. Preferably, the temperature control body 7.2 directly abuts against the heating tube assembly 2, thereby accurately controlling the heating tube assembly 2.

[0027] Preferably, the temperature control base 7.1 is provided with a notch 7.3. In the vertical direction, the wiring part of the temperature control body 7.2 is exposed in the notch 7.3 and is arranged directly opposite the wiring board. Furthermore, the wiring part of the temperature control body 7.2 is located in the first part 3.1 near the entrance and exit of the neutral wire channel 1.4.

[0028] Furthermore, a reset part 7.4 is disposed in the middle of the temperature control body 7.2. The reset part 7.4 is used to reset the temperature control body 7.2 after it is disconnected. A guide part 7.5 is provided on the top of the temperature control base 7.1. The guide part 7.5 is connected to the reset part 7.4 so that an external component can act on the reset part 7.4 through the guide part 7.5. The guide part 7.5 is disposed through the circuit board 5, and a reset hole 10.3 corresponding to the guide part 7.5 is provided on the protective cover 10. The reset hole 10.3 is filled with a protective member.

[0029] like Figures 7 to 12 As shown, as a further embodiment of the water pressure switch 6, a hot water inlet channel 1.5 is provided at the top of the water outlet housing 1. The hot water inlet channel 1.5 is arranged along the extension direction of the water outlet housing 1. In hot water mode, the hot water inlet channel 1.5 is connected to the water inlet 1.1. The water pressure switch 6 is located at one end of the hot water inlet channel 1.5. The hot water inlet channel 1.5 is connected to the water-facing surface of the water pressure switch 6. The water pressure switch 6 receives the incoming water flow in the hot water inlet channel 1.5 and conducts the heating module.

[0030] Specifically, the water pressure switch 6 includes a switch housing 6.1 fixed on the second region 4, and a first conductive plate 6.2 and a second conductive plate 6.3 movably disposed on the switch housing 6.1. The switch housing 6.1 also contains a valve diaphragm 6.5 abutting the end of the hot water inlet channel 1.5. The water-facing side of the valve diaphragm 6.5 is in contact with the hot water inlet channel 1.5, and its back-water portion is connected to the second conductive plate 6.3 via a rod. The first conductive plate 6.2 is connected to the circuit board 5. The switch housing 6.1 has an extension arm 6.4 for mounting the second conductive plate 6.3. The extension arm 6.4 is inserted into the live wire end 2.1 of the heating element assembly, and the second conductive plate 6.3 is electrically connected to the live wire end 2.1 of the heating element assembly 2. Under the action of the incoming water flow, the valve diaphragm 6.5 bears the water pressure and moves towards the first conductive plate 6.2. At this time, the valve diaphragm 6.5, through the rod, drives the second conductive plate 6.3 to abut against the first conductive plate 6.2, thus realizing the circuit conduction of the heating element assembly 2.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, the switch housing 6.1 is fitted with the live wire end 2.1 of the heating tube assembly 2, and the extension arm 6.4 is preferably embedded in the live wire end 2.1 of the heating tube assembly 2, which is provided with a conductive connector.

[0032] Optionally, the conductive connector and the second conductive piece 6.3 are mechanically and electrically connected through a conductive insert, realizing a wireless electrical connection, simplifying assembly, and simultaneously achieving mutual positioning between the water pressure switch 6 and the live wire end 2.1 of the heating tube group 2, improving connection reliability and mechanical strength.

[0033] In some embodiments, the first region 3 is further provided with a temperature-conducting element 8 passing through the hot water inlet channel 1.5 and a semiconductor 8.1 abutting against the temperature-conducting element 8. The semiconductor 8.1 is connected to the circuit board 5. The temperature-conducting element 8 and the semiconductor 8.1 are specifically disposed on the second part 3.2, and the temperature-conducting element 8 is embedded in the top wall of the water outlet housing 1 in the second part 3.2. The circuit board 5 is provided with a clearance opening 5.1 corresponding to the semiconductor 8.1.

[0034] In some embodiments, a temperature sensor 9 is also disposed within the first region 3. The temperature sensor 9 is placed in the heating chamber 1.3 through the first region 3. The temperature sensor 9 is connected to the circuit board 5. The circuit board 5 is provided with a clearance opening 5.1 corresponding to the temperature sensor 9. Preferably, the temperature sensor 9 is covered by a temperature sensing kit on its outside. The temperature sensing kit can be made of silicone. The temperature sensing kit is disposed within the first part 3.1. The temperature sensor 9 is inserted into the temperature sensing kit. The circuit board 5 covers the first part 3.1, and the clearance opening 5.1 on the circuit board 5 allows the circuit of the temperature sensor 9 to be led out to the circuit board 5 for easy circuit connection.

[0035] The aforementioned semiconductor 8.1 and temperature sensor 9 constitute an electronic control component.

[0036] from Figure 5 As can be seen, a grounding connector 12 is also embedded on the surface of the water outlet shell 1 that is away from the heating chamber 1.3.

[0037] Reference Figure 3 As shown in the figure, as a further improvement to the outlet housing 1, in this embodiment, the outlet housing 1 includes a first housing 1.6 and a second housing 1.7 arranged opposite to each other. A splicing part 1.8 is provided between the first housing 1.6 and the second housing 1.7, and a sealing connector 1.9 is tightly connected to the splicing part 1.8. The outlet housing 1 is divided about the longitudinal section to form a left-right split first housing 1.6 and second housing 1.7. The electrical control installation area is set on the second housing 1.7, and the control valve 13 and the water inlet 1.1 are set on the first housing 1.6. Thus, during assembly, pre-assembly can be completed on the first housing 1.6 and the second housing 1.7 respectively. More assembly space can be freed in the second housing 1.7 to pre-assemble the temperature control switch, the circuit board 5 and the water pressure switch 6 on the second housing 1.7. After the splicing of the first housing 1.6 and the second housing 1.7 and the connection of the neutral wire are completed, the circuit board 5 is covered and fixed in the first area 3, and finally the protective cover 10 is fixed.

[0038] Specifically, the splicing part 1.8 and the sealing connector 1.9 are provided with a wire passage 1.81 corresponding to the neutral wire channel 1.4. The sealing connector 1.9 is arranged around the wire passage 1.81. The sealing connector 1.9 further seals the split water outlet shell 1, and the sealing effect of the sealing connector 1.9 extends to the wire passage 1.81 of the neutral wire channel 1.4, ensuring the sealing reliability of the neutral wire channel 1.4.

[0039] The sealing connector 1.9 is provided with a sealing profile that matches the wire passage 1.81. The splicing part 1.8 has a housing mating part 1.82 and a wire passage mating part 1.83. The housing mating part 1.82 protrudes from the surface of the wire passage mating part 1.83 and forms a concave structure relative to the housing mating part 1.82. The sealing connector 1.9 has an extension profile that extends toward the splicing part 1.8 and is embedded in the aforementioned concave structure, thereby further ensuring the sealing performance of the neutral wire channel 1.4.

[0040] A control valve 13 is provided on the end of the outlet housing 1 away from the electrical control installation area. This control valve 13 is used to control the cold water output mode or the hot water output mode, and to balance the weight distribution of the outlet housing 1 away from the electrical control installation area. It should be noted that the outlet housing 1 also has a cold water inlet channel 1.61 and a cold water outlet channel 1.62. The cold water inlet channel 1.61 is connected to the water inlet 1.1. In the hot water output mode, the control valve 13 is connected to the water inlet 1.1, and the cold water inlet channel 1.61 is connected to the hot water inlet channel 1.5. In cold water mode, control valve 13 disconnects the hot water inlet channel 1.5 and connects the cold water inlet channel 1.61 and the cold water outlet channel 1.62 to allow water from inlet 1.1 to directly enter the heating chamber 1.3. Control valve 13 controls the connection between cold water inlet channel 1.61 and hot water inlet channel 1.5 by rotating the gear, or controls the connection between cold water inlet channel 1.61 and cold water outlet channel 1.62. In some embodiments, control valve 13 can also close inlet 1.1 and cold water inlet channel 1.61.

[0041] The control valve 13 is a conventional valve body in the prior art, which realizes the connection of cold water or hot water by rotating the gear, and will not be described in detail here.

[0042] like Figure 12As shown, as a further embodiment of the heating chamber 1.3, in this embodiment, the heating tube assembly 2 specifically refers to the heating tube assembly 2. The ends of the first housing 1.6 and the second housing 1.7 are provided with a first fixed space and a second fixed space for accommodating the ends of the heating tube assembly 2. The ends of the heating tube assembly 2 are provided with sealing rings that abut against the first fixed space and the second fixed space. The heating tube assembly 2 has a tube portion with a first outer diameter and an end seat with a second outer diameter. Thanks to the left and right split configuration of the first housing 1.6 and the second housing 1.7, there is no need to provide a completely through fixed space on the first housing 1.6 and the second housing 1.7. It is only necessary to allow the electrical connection part on the end seat to extend, which improves the assembly reliability of the heating tube assembly 2. During the assembly process, the left and right split first housing 1.6 and the second housing 1.7 are spliced ​​and embraced at both ends of the heating tube assembly 2.

[0043] like Figure 7 , Figures 10 to 14 As shown, to further explain the hot water output mode, the outlet housing 1 is also provided with a water passage 1.51 connecting the water-facing surface and the heating chamber 1.3. When there is no water flow, the valve diaphragm 6.5 abuts against the water passage 1.51. When the control valve 13 is set to the hot water position, the incoming water flows through the inlet 1.1 and sequentially into the cold water inlet channel 1.61 and the hot water inlet channel 1.5. Then the incoming water flows onto the valve diaphragm 6.5. Under the action of the water flow, the valve diaphragm 6.5 presses against the conductive sheet group, so that the heating tube group 2 is energized. At this time, the valve diaphragm 6.5 deforms and releases the water passage 1.51. Then the water flows through the water passage 1.51, enters the heating chamber 1.3 and is heated, and finally is discharged from the outlet 1.2.

[0044] Specifically, the temperature control switch and the water pressure switch are connected in series in the live wire circuit of the heating tube assembly, and are located on the upstream and downstream sides of the heating tube assembly, respectively, forming at least two series-connected circuit break control points in the live wire circuit. When either the water pressure switch or the temperature control switch breaks the circuit due to a fault, the power supply to the entire live wire of the heating tube assembly is cut off to prevent the heating tube assembly from dry burning.

[0045] 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.
