Description

Technical Field

[0001] This utility model relates to a precision ceramic valve with two bottom inlets and three outlets, and more particularly to a precision ceramic valve that can be used to switch water sources for three different water-using devices. Background Technology

[0002] Ceiling-mounted shower heads and wall-mounted handheld shower heads typically offer both cold and hot water options. Warm water is obtained by simultaneously introducing cold water and mixing it with hot water in equal proportions before controlling the flow. This mixing ratio can be adjusted to achieve the desired water temperature. The mixing of cold and hot water is controlled primarily by turning a ceramic valve. However, since each ceramic valve can only supply water to one type of device, if the same cold and hot water source needs to supply water to both the fixed shower head and the handheld shower head, an additional ceramic valve is required. The cold and hot water must then be diverted to the two ceramic valves via a distributor and water pipes. Furthermore, both types of devices need to have a bottom-flow mode for use with bathtubs and other containers. This significantly increases the complexity of the entire water piping system and makes its construction more difficult.

[0003] Therefore, how to develop and improve the existing structure to address its shortcomings is a goal that the relevant industry needs to strive for. In view of this, the applicant conceived this utility model, designed it based on years of experience, and after extensive discussions, sample testing, and multiple revisions and improvements, launched this utility model. Utility Model Content

[0004] The technical issues to be addressed:

[0005] The existing ceramic valve can only be used with one type of water-using equipment, which is the technical problem we want to solve.

[0006] Technical means to solve the problem:

[0007] This utility model provides a precision ceramic valve with two inlets and three outlets. The valve has a rotating seat inside a valve housing. Below the rotating seat, inside the valve housing, are a first movable valve plate, a second movable valve plate, and a fixed valve plate stacked sequentially. The rotating seat has a control rod extending upwards from the valve housing, through which a valve stem passes. By engaging the rotating seat and the valve stem with the second movable valve plate and the first movable valve plate respectively, the second movable valve plate or the first movable valve plate can be rotated by operating the rotating seat or the valve stem. The valve housing has an opening and a base, allowing the fixed valve plate and the... The second movable valve plate, the first movable valve plate, and the rotating seat can be sequentially inserted into the valve housing through the opening and supported on the base. The base is provided with a cold water inlet, a hot water inlet, and a first water outlet. A second water outlet and a third water outlet are respectively provided on both sides of the first water outlet. The opening is fitted with a cover, and the cover has a through hole in the center, allowing the inner and outer valve rods and the control rod to pass through the through hole and exit the valve housing together. After the valve rod passes through the control rod, its side end extends out of the control rod. When the control rod is not stuck, the valve rod and the control rod can be tightly closed to allow the valve housing to function properly. The valve stem can be rotated along with the control lever when it rotates. The first movable valve plate has a cold water passage hole and a hot water passage hole, and both sides of the first movable valve plate have a flat cut. The second movable valve plate has a cold water flow hole and a hot water flow hole, and one side edge has a water guide notch. Under normal non-use conditions, the cold water flow hole and the hot water flow hole will avoid each other, achieving a water shut-off effect where neither cold nor hot water can flow out. The fixed valve plate has a cold water hole, a hot water hole, a first water outlet hole, a second water outlet hole, and a third water outlet hole. When the fixed valve plate is released... When the valve plate is inserted into the valve housing and secured on the base, the cold water hole, hot water hole, first outlet hole, second outlet hole, and third outlet hole of the fixed valve plate can be aligned with the cold water inlet, hot water inlet, first outlet, second outlet, and third outlet of the valve housing, respectively. The design of the cold water hole and hot water hole as long arc-shaped holes ensures that the second movable valve plate remains connected to the cold water hole and hot water hole of the fixed valve plate during rotation. Therefore, a precision ceramic valve with two bottom inlets and three outlets can be obtained.

[0008] Compared to existing technologies, the following benefits are achieved:

[0009] This utility model provides a precision ceramic valve with two bottom inlets and three outlets. By using the same precision ceramic valve, the use and control of three water-using devices can be achieved. During use and control, it also has the function of mixing cold water and hot water. In this way, it is not necessary to install a water distributor and connect additional water pipes between the three water-using devices and the cold and hot water sources, which effectively simplifies the complexity of the entire water pipeline and makes the pipeline construction simpler, saving time and effort.

The cold water hole 51 and the hot water hole 52 of the fixed valve plate 50 are respectively formed with an expansion portion 511 and an expansion portion 521 on one side of the hole edge. By using the concave arrangement of the expansion portion 511 and the expansion portion 521 from bottom to top, the coverage area of ​​the cold water hole 51 and the hot water hole 52 can be increased, so that the cold water hole 51 and the hot water hole 52 can be smoothly connected with the cold water inlet 13 and the hot water inlet 14.

[0098] This utility model provides a precision ceramic valve with two inlets and three outlets, wherein the precision ceramic valve is installed in a water distribution valve seat 70 during use (please also refer to...). Figures 15 to 20 As shown), the water distribution valve seat 70 has a valve chamber 71 pre-installed. The valve chamber 71 is connected to a cold water inlet channel 72, a hot water inlet channel 73, a first outlet channel 74, a second outlet channel 75, and a third outlet channel 76. The cold water inlet channel 72 and the hot water inlet channel 73 are used to connect cold water C and hot water H.

When the precision ceramic valve is placed in the valve chamber 71, the cold water inlet 13, hot water inlet 14, first outlet 15, second outlet 16, and third outlet 17 of the valve body 10 are respectively connected via the cold water inlet 72, hot water inlet 73, first outlet 74, second outlet 75, and third outlet 76.

[0099] This utility model provides a precision ceramic valve with two bottom inlets and three outlets. The valve seat 70 is embedded in the wall and connected to the water faucet (first water-using device) below via the first outlet 74. The second outlet 75 is used to connect to the wall-mounted shower head (second water-using device) above, and the third outlet 76 is used to connect to the shower head (third water-using device) fixed on the ceiling.

[0100] This utility model provides a precision ceramic valve with two inlets and three outlets, wherein the control rod 21 of the rotating seat 20 and the valve stem 22 are jointly equipped with a switching control group 80 (please refer to the same). Figures 15 to 20As shown, the switching control group 80 has a fixed ring 81, a panel 82, a first handle 83, and a second handle 84. The fixed ring 81 is locked onto the outside of the cover 18 and has three slots 811. The panel 82 has three indicator symbols 821 corresponding to these three slots 811. These three indicator symbols 821 represent a water-using device. In addition, the first handle 83 is fixedly connected to the control lever 21, and the second handle 84 is fixedly connected to the valve stem 22. The first handle 83 is equipped with a button 86 that is pushed outward by a spring 85. The button 86 is also connected to a lever 87. By pressing the button 86, the lever 87 is moved out of its original position. When the first handle 83 drives the control lever 21 to rotate, water from a specific water-using device can be selected. After rotation, the release of the button 86 causes the lever 87 and the button 86 to be actively returned by the spring 85 to engage in another slot 811, allowing the first handle 83 to be relocked. The second handle 84 can then drive the valve stem 22 to rotate to adjust the water temperature. Since the first handle 83 rotates in tandem with the control lever 21 and the valve stem 22, the adjusted water temperature can be prevented from being arbitrarily changed. The switching control group 80 can be used by first setting the water temperature and then selecting the desired water-using device.

[0101] This utility model provides a precision ceramic valve with two bottom inlets and three outlets, wherein the control rod 21 is provided with an external toothed part and the first handle 83 is provided with an internal toothed part, so that the control rod 21 and the first handle 83 can be interlocked by the external toothed part and the internal toothed part.

[0102] This utility model provides a precision ceramic valve with two bottom inlets and three outlets, wherein the control rod 21 and the first handle 83 are locked together by screws (please also refer to...). Figure 21 (As shown).

[0103] In actual use, with the control lever 21 locked to the first handle 83, the water temperature is adjusted by first rotating the second handle 84 together with the valve stem 22. After the valve stem 22 rotates, it will drive the first movable valve plate 30 to rotate, so as to align the cold water through hole 31 with the cold water flow hole 41 (please refer to the following). Figure 8(As shown), the cold water C flowing in from the cold water inlet 13, balance valve 60, cold water hole 51, cold water flow hole 41, and cold water through hole 31 can be transferred through the water guide notch 43 and discharged from the water-using device; in addition, during the water discharge process, if warm water is to be used at the same time, or even hot water H is used only, the hot water through hole 32 can be gradually overlapped with the hot water flow hole 42 by continuously rotating the second handle 84. The size of the overlap can be adjusted according to the different rotation amplitudes. When the cold water through hole 31 and the hot water through hole 32 are simultaneously connected to the cold water flow hole 41 and the hot water flow hole 42, the cold water C and the hot water H will mix to form warm water for use (please also refer to...). Figure 9 As shown), when the second handle 84 is turned to its maximum stroke position, allowing cold water to completely or significantly bypass the cold water flow hole 41 through the hole 31, hot water H can flow out for use (please also refer to...). Figure 10 As shown), when you want to turn off the water, simply turn the second handle 84 back. Hot water H flows in from the hot water inlet 14, the balance valve 60, the hot water hole 52, the hot water flow hole 42, and the hot water through hole 32, and then flows into the guide hole 43.

[0104] Furthermore, after adjusting the outlet water temperature, if water needs to be dispensed through different water-using devices, first release the locking state of the first handle 83. This allows the first handle 83 to drive the control lever 21 and valve stem 22 to rotate together. During this rotation, the first movable valve plate 30 and the second movable valve plate 40 maintain their adjusted alignment, ensuring the adjusted water temperature does not change due to the rotation of the second movable valve plate 40. Simultaneously, the water guide notch 43 of the second movable valve plate 40 can be aligned with the first outlet hole 53 and the second outlet hole 54 as needed (please also refer to...). Figure 11 and Figure 12 (as shown) or the third water outlet 55 (please also refer to) Figure 13 and Figure 14 As shown, water can flow out from the water guide notch 43, the first water outlet 53, the first water outlet 15 through the first water outlet channel 74, or from the water guide notch 43, the second water outlet 54, the second water outlet 16 through the second water outlet channel 75, or from the water guide notch 43, the third water outlet 55, the third water outlet 17 through the third water outlet channel 76, so that the same precision ceramic valve can control three different water-using devices at the same time.

[0105] The structure of the above specific embodiments can achieve the following beneficial effects: by using the same precision ceramic valve, the use and control of three water-using devices can be achieved. During use and control, it also has the function of mixing cold water C and hot water H. In this way, it is not necessary to install a water distributor and connect water pipes separately between the three water-using devices and the cold and hot water sources, which effectively simplifies the complexity of the entire water pipeline and makes the pipeline construction simpler, saving time and effort.

[0106] In summary, this utility model has indeed achieved a breakthrough in structural design, possesses improved utility model content, and can achieve industrial applicability and progress. Moreover, this utility model has not been published in any publication.

[0107] However, the above is only a preferred embodiment of the present utility model and should not be used to limit the scope of the present utility model; that is, any equivalent changes and modifications made in accordance with the claims of the present utility model should still fall within the protection scope of the present utility model.
