Description

Technical Field

[0001] This utility model relates to the field of water outlet device technology, and more specifically, to a water outlet device with dual-control water circuits. Background Technology

[0002] Currently, to prevent the solenoid valve switch of sensor faucets from malfunctioning and failing to dispense water, existing sensor faucets typically offer both automatic and manual water dispensing modes. However, these faucets have a complex structure and high cost, and the control box for the electronic switch is usually installed under the counter, making installation difficult for ordinary consumers.

[0003] While some existing sensor faucets solve the above-mentioned technical problems—for example, Chinese utility model patent application CN202121680297.2, "Valve Core Seat and Valve Core Module Assembly," discloses a structure that achieves dual control with a single valve core, in which the electronic control switch is installed on the valve core seat—its water circuit structure results in vertical water inlet and outlet, making it suitable only for kitchen faucets and not for sink faucets with side-discharge water flow. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a water outlet device with dual-control water circuits to solve the above problems.

[0005] The present invention adopts the following solution:

[0006] This application provides a water outlet device with dual-control water circuits, including a central body, a valve core disposed within the body, a valve core seat disposed within the body, and an electric control switch mounted on the valve core seat;

[0007] The valve core seat has at least one through-water inlet channel arranged vertically inside, and the top end face forms a mounting surface adapted to the valve core; the valve core seat has two outlet channels penetrating the mounting surface, and the side wall has at least one outlet communicating with the outlet channel; the outer peripheral wall of the valve core seat has a first sealing mounting groove for installing a first sealing element on the outer periphery of the outlet; the electric control switch is used to control the connection between one of the outlet channels and the outlet; the side wall of the body has an opening communicating with the inner cavity of the outlet support arm.

[0008] Furthermore, the first sealing mounting groove is configured to follow the shape of the water outlet.

[0009] Furthermore, the sealing mounting groove is generally square-shaped and annular, with multiple limiting parts protruding into the groove on its side wall; and the inner wall has a notch in the vertical direction; the sealing element includes an annular body adapted to the sealing mounting groove, with a connecting rib in the middle vertically connecting the annular body and the notch; the inner side of the annular body is adapted to the bottom wall of the first sealing mounting groove, and the outer side has a full circle of arc protrusion.

[0010] Furthermore, it also includes a first housing sleeved outside the main body, and the water outlet arm is disposed on the first housing; the first housing is sealed to the main body through at least one second sealing member so that the inner cavity of the water outlet arm is sealed to communicate with the opening.

[0011] Furthermore, a second sealing mounting groove for installing a second sealing element is provided on the outer peripheral wall of the body, located around the opening.

[0012] Furthermore, a full-circle sealing groove is provided on the outer peripheral wall of the body on the upper and lower sides of the opening for installing a sealing ring; a water outlet cavity is formed between the first housing and the body, which communicates with the opening and the inner cavity of the water outlet support arm.

[0013] Furthermore, it also includes a second housing fitted onto the main body and positioned below the first housing; the main body is provided with an opening window for installing a sensor electrically connected to the electronically controlled switch; the second housing is provided with a sensor window adapted to the sensor.

[0014] Furthermore, a mounting cavity with a downward opening is provided on the bottom of the valve core seat for mounting the electronic control switch.

[0015] Furthermore, the valve core has two switching states. The first switching state is used to independently control the connection between one of its water outlet channels and the valve core water outlet channel, thereby realizing the water outlet. The second switching state controls the connection between the other water outlet channel and the valve core water outlet channel, and controls the connection between the other water outlet channel and the water outlet through the electronic control switch.

[0016] Furthermore, the valve core has a third switching state for closing both of the water outlet channels.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] Compared to existing technologies, this solution allows for separate control of two water paths via an electronic switch and a valve core. This means that even if the electronic switch fails, the water flow can still be controlled by adjusting the valve core's on / off state using a handle. Furthermore, the valve core seat design is simple and suitable for side-discharge sink faucets. The sealing element is only installed around the water outlet, requiring minimal dimensional precision to ensure a tight seal. It is also easy to manufacture and cost-effective.

[0029] Example

[0030] Combination Figures 1 to 7 As shown, this embodiment provides a water outlet device with dual-control water circuits, including a body 1 with a central through-hole, a valve core 2 disposed in the body 1, a valve core 2 seat disposed in the body 1, and an electric control switch 4 installed on the valve core 2 seat;

[0031] The valve core 2 seat has at least one through water inlet channel 7 arranged vertically inside, and the top end face forms a mounting surface 8 adapted to the valve core 2; the valve core 2 seat has two water outlet channels that penetrate the mounting surface 8, and the side wall has at least one water outlet 9 that communicates with the water outlet channel; the outer peripheral wall of the valve core 2 seat is provided with a first sealing mounting groove 13 for installing the first sealing element 12 on the outer periphery of the water outlet 9; the electric control switch 4 is used to control the connection between one of the water outlet channels and the water outlet 9; the side wall of the body 1 is provided with an opening 14 that communicates with the inner cavity of the water outlet support arm 6.

[0032] In this embodiment, a first housing 5 with a water outlet support arm 6 is sleeved outside the main body 1. The inner cavity of the main body 1 is provided with a first limiting step; the upper end of the valve core 2 seat is provided with a second limiting step adapted to the limiting step, and the mounting surface 8 is the upper end surface of the second limiting step. The valve core 2 seat can be inserted through the upper opening of the inner cavity of the main body 1 and is limited and fixed by the limiting steps.

[0033] like Figures 3 to 7 As shown, this embodiment takes a temperature-adjustable valve core 2 as an example. Therefore, the valve core 2 seat has two water inlet channels 7, with connecting parts at its bottom for screwing cold water inlet pipes and hot water inlet pipes, respectively. Two water outlet channels penetrating the mounting surface 8 are the first water outlet channel 10 and the second water outlet channel 11. The first sealing mounting groove 13 is generally square-shaped and annular. Limiting parts 16 protruding into the groove are provided on the upper and right side walls of the groove; and a notch 17 is provided vertically on its inner side baffle. The first sealing element 12 includes an annular body 18 adapted to the sealing mounting groove. A connecting rib 19, adapted to the notch 17, is provided vertically in its middle portion; the inner side of the annular body 18 is adapted to the bottom wall of the first sealing mounting groove 13, and a full-circle arc protrusion 20 is provided on its outer side. The limiting part 16 is used to limit the first sealing member 12 to prevent it from falling outward. The connecting rib 19 prevents the first sealing member 12 from being dislodged when it is installed in the body 1 due to contact between it and the inner wall of the body 1. This sealing member, unlike the traditional circular sealing rings on the upper and lower sides of the outlet 9, does not have roundness requirements, or rather, the roundness requirement is low, which is sufficient to ensure sealing. Furthermore, it is not limited to whether the outer peripheral wall of the valve core 2 seat and the inner peripheral wall of the body 1 are cylindrical. It should be noted that the first sealing mounting groove 13 follows the shape of the outlet 9, and it can also be racetrack-shaped, elliptical, or other shapes.

[0034] In this embodiment, as Figure 2 As shown, the first housing 5 is rotatably fitted onto the body 1; a full-circumference sealing groove 21 is provided on the outer peripheral wall of the body 1 on both the upper and lower sides of the opening 14 for installing the second sealing element 15, wherein the second sealing element 15 is a shaped sealing ring; a water outlet cavity 22 is formed between the first housing 5 and the body 1, communicating with the opening 14 and the inner cavity of the water outlet support arm 6. This structure allows the water outlet support arm 6 to rotate 360 ​​degrees, facilitating user adjustment of the water outlet position. The shaped sealing ring achieves a better sealing effect under water pressure. To enable the water outlet cavity 22 to quickly fill with water and the water outlet support arm 6 to quickly discharge water, multiple water outlets 9 can be provided on the valve core 2 seat.

[0035] Of course, in other embodiments, the first housing 5 may also be fixedly sleeved on the body 1; a second sealing mounting groove for installing the second sealing element 15 is provided on the outer peripheral wall of the body 1, located around the opening 14. The structure of the second sealing mounting groove and the second sealing element 15 may be consistent with the structure of the first sealing mounting groove 13 and the first sealing element 12.

[0036] In this embodiment, a mounting cavity 23 with a downward opening is provided at the bottom of the valve core 2 seat for mounting the electric control switch 4. Specifically, the mounting cavity 23 includes a control cavity 24 communicating with the second water outlet channel 11 and the water outlet 9. The electric control switch 4 is a solenoid valve electrically connected to a sensor 26. The solenoid valve controls the opening and closing of the control cavity 24, thereby controlling the communication between the second water outlet channel 11 and the water outlet 9. A second housing 27 is fitted onto the body 1 below the first housing 5. The body 1 has an opening window 25 with a connecting part on its inner side. The sensor 26 is attached to the connecting part by screws, and the sensor 26 is placed on the sensing window on the second housing 27 through the opening window 25. In this embodiment, the first housing 5 and the water outlet support arm 6 can be formed by processing tubular profiles, and can be connected to the first housing 5 by welding.

[0037] In this embodiment, the valve core 2 has two switching states. The first switching state independently controls the connection between the first water outlet channel 10 and the valve core's water outlet channel, thereby enabling water to flow from the outlet 9. The second switching state controls the connection between the second water outlet channel 11 and the valve core's water outlet channel, and the connection between the second water outlet channel 11 and the outlet 9 is controlled by the electronic control switch 4. That is, when the valve core 2 is in the first switching state, it can independently control the water flow from the water outlet arm 6, i.e., manually control the water flow; while when the valve core 2 is in the second switching state, the water flow from the water outlet arm 6 needs to be controlled by the electronic control switch 4, i.e., sensor-activated water flow. Of course, the valve core 2 can also have a third switching state, used to close both water outlet channels.
