Description

Technical Field

[0001] This invention relates to the field of water outlet device technology, and more specifically, to a linkage control water distributor and water outlet device. Background Technology

[0002] Currently, many water dispensing devices, in order to meet user needs, typically include an additional water outlet branch for connecting a spray gun or showerhead; and the spray gun or showerhead usually has its own switch for easier operation and control. However, in existing technology, although each branch has an independent water flow control switch, they are all connected to the same main water outlet pipe. This means that when the water dispensing device and the spray gun or showerhead are dispensing water simultaneously, the water flow from both branches is relatively low and cannot meet the usage requirements. To ensure the water flow needs of one branch, the water flow from the other branch must be shut off first. For example, if a water outlet branch is added to a conventional faucet to connect to a spray gun, when the user needs to briefly use the spray gun while using the faucet, they must first turn off the faucet and then turn the spray gun on to ensure sufficient water flow for rinsing. This switching method is cumbersome and results in a poor user experience. Summary of the Invention

[0008] Furthermore, the water distribution assembly includes a valve stem, a seat, a second sealing element and a third sealing element sleeved at both ends of the valve stem; the seat is sealed on the opening at one end of the water distribution chamber, and the outer end of the seat is provided with a movable cavity, and the middle of the sealing platform at the bottom is provided with a water passage; the valve stem is movably disposed in the water distribution chamber, the second sealing element and the third sealing element are respectively placed on both sides of the mixing inlet, and the third sealing element is placed in the movable cavity; the pressure-bearing area of ​​the second sealing element is greater than that of the third sealing element.

[0009] Furthermore, the second seal is generally frustum shaped, and a deformation groove is provided on the end face of the larger end so that the outer edge of the larger end forms an elastic sealing part.

[0010] Furthermore, the outer end face of the base is provided with a plurality of protrusions at intervals, which can abut against the side wall of the mounting cavity; a water passage is formed between the protrusions.

[0011] Furthermore, multiple ribs are evenly distributed inward on the sidewall of the movable cavity.

[0012] Furthermore, the sealing platform is provided with multiple support arms to provide axial support and guidance for the valve stem.

[0013] This application also provides a water outlet device, including the aforementioned linkage control water distributor, wherein the first water outlet channel and the second water outlet channel are respectively used to connect to any two of a faucet, a handheld shower head, an overhead shower head, and a spray gun.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: This application provides a linkage control water distributor and water outlet device, which, through a structure including a housing with an installation cavity, a control valve, and a water distribution valve, enables water to flow when the first water outlet channel is open, automatically switch to the second water outlet channel and close the first water outlet channel after the second water outlet channel is opened, and automatically resume water flow from the first water outlet channel after the second water outlet channel is closed.

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example Combination Figures 1 to 5 As shown, this embodiment provides a linkage control water distributor, including a main body 1 with an installation cavity, a control valve 2 disposed in the installation cavity, and a water distributor 3 that forms an end face seal with the control valve 2; The control valve 2 and the water distribution valve 3 form a first side seal and a second side seal with the mounting cavity, respectively, thereby forming a first mixing outlet cavity 4 for connecting to the first outlet channel; the body 9 of the water distribution valve 3 is provided with a water distribution cavity 5 with one end open and connected to the first mixing outlet cavity 4, and a water distribution component is provided inside; the other end of the water distribution cavity 5 is connected to the second mixing outlet cavity 17 for connecting to the second outlet channel; a mixing inlet 6 is opened in the middle and connected to the mixing outlet of the control valve 2; a first inlet channel 7 and a second inlet channel 8 are respectively provided through the water distribution cavity 5 on both sides and are respectively connected to the two inlets of the control valve 2; When the first water outlet channel is opened, the water distribution component enables the first mixing water outlet chamber 4 to connect with the mixing water outlet, thereby enabling water to flow out of the first water outlet channel; and after the second water outlet channel is opened, the second mixing water outlet chamber 17 is connected with the mixing water outlet, thereby enabling water to flow out of the second water outlet channel, while automatically closing the connection between the first mixing water outlet chamber 4 and the mixing water outlet; and after the second water outlet channel is closed, water flow out of the first water outlet channel is restored.

[0019] In this embodiment, the linkage between the faucet and the spray gun 24 is used for specific explanation. The main body 1 is the faucet body 9. The mounting cavity is configured with openings at the top and bottom, and a limiting step is provided at the bottom opening. The control valve 2 and the water distribution valve 3 can be inserted into the limiting step from the top opening and locked onto the limiting step. Specifically, the control valve 2 is a conventional valve core that can realize the functions of switching and temperature adjustment.

[0020] The water distribution chamber 5 of the main body 9 is arranged radially. A first water inlet channel 7 and a second water inlet channel 8 are arranged through both sides of the water distribution chamber 5 and are respectively connected to the two water inlets of the control valve 2. The water inlet sections of the first water inlet channel 7 and the second water inlet channel 8 connected to the external water circuit are arranged axially to facilitate quicker connection of the water inlet pipe. The bottom end face of the housing of the control valve 2 is provided with a first sealing groove, and a first sealing element 10 is provided on the first sealing groove to achieve sealing with the end face of the main body 9. The upper side wall of the housing is provided with a second sealing groove, and a first sealing ring 11 is fitted on the second sealing groove. The lower side wall of the main body 9 is provided with a third sealing groove, and a second sealing ring 12 is fitted on the third sealing groove. The first mixing outlet chamber 4 is formed between the first sealing ring 11 and the second sealing ring 12.

[0021] like Figures 3 to 5 As shown, the water distribution assembly includes a valve stem 13, a seat 14, a second sealing element 15 and a third sealing element 16 sleeved at both ends of the valve stem 13; the seat 14 is sealed on the opening at one end of the water distribution chamber 5, and the outer end of the seat 14 is provided with a movable cavity, a water passage is provided in the middle of the sealing platform on the bottom side, and multiple support arms 22 are provided on the sealing platform to provide axial support and guidance for the valve stem 13; the valve stem 13 is movably disposed in the water distribution chamber 5, the second sealing element 15 is respectively placed on both sides of the mixing inlet 6, and the third sealing element 16 is placed in the movable cavity; the pressure-bearing area of ​​the first sealing element 10 is larger than the pressure-bearing area of ​​the second sealing element 15. The second sealing element 15 is generally frustum-shaped, and a deformation groove 18 is provided on the end face of the larger end to form an elastic sealing part 19 on the outer edge of the larger end.

[0022] In this embodiment, the outer end face of the seat 14 is provided with a plurality of protrusions 20 spaced apart, which can abut against the side wall of the mounting cavity; a water passage is formed between the protrusions 20. A plurality of ribs 21 are evenly distributed inward on the side wall of the movable cavity. The ribs 21 provide radial support and guidance for the movement of the valve stem 13, and the arrangement of the ribs 21 forms a water passage between the movable cavity and the valve stem 13. The arrangement of the water passage ensures that the water flow can smoothly bypass the seat 14 and enter the first mixing outlet cavity 4.

[0023] The main body 1 has a water outlet 23 on its side wall that connects to the first mixing water outlet chamber 4; the second mixing water outlet chamber 17 is arranged axially to connect to the water distribution chamber 5 and is connected to the spray gun 24 by a water outlet pipe.

[0024] The control valve 2 is controlled by a handle. When the control valve 2 is opened, the mixed water enters the water distribution chamber 5 through the mixing inlet 6. Under the action of water pressure, the valve stem 13 moves to the right. At this time, the second seal 15 moves away from the sealing platform, and the first mixing outlet chamber 4 connects with the mixing inlet 6, allowing water to flow out through the outlet nozzle 23. When the spray gun 24 is opened at this time, because the pressure-bearing area of ​​the first seal 10 is greater than that of the second seal 15, the valve stem 13 moves to the left. The second seal 15 moves closer to the sealing platform to form a seal, and the first mixing outlet chamber 4 disconnects from the mixing inlet 6, preventing water from flowing out of the outlet nozzle 23. At the same time, under the action of water pressure, the sealing part 19 is compressed and deformed inward, allowing water to flow into the second mixing outlet chamber 17. At this time, only the spray gun 24 outputs water. When the spray gun 24 is closed, the valve stem 13 moves to the right again under the action of water pressure. At this time, the second seal 15 moves away from the sealing platform, and the first mixing water outlet chamber 4 is connected to the mixing water inlet 6 and the water outlet 23 is used to output water.

[0025] The above achieves water flow when the first water outlet is open, and automatically switches to the second water outlet when the second water outlet is opened, while closing the first water outlet. Furthermore, the first water outlet automatically resumes flow after the second water outlet is closed. This solves the problem of multiple water outlet branches not being able to coordinate and operate automatically. It has the advantages of achieving automatic switching of water outlet branches, avoiding water pressure dispersion, improving water flow efficiency and ease of use.

[0026] This application also provides a water outlet device, including the aforementioned linkage control water distributor, wherein the first water outlet channel and the second water outlet channel are respectively used to connect to any two of the following: a faucet, a handheld shower head, an overhead shower head, and a spray gun 24.
