Description

Technical Field

[0001] This invention relates to a multifunctional switching valve. Background Technology

[0002] Currently, most push-button switching valves are large in size, with multiple buttons and flow control knobs designed separately, making them inconvenient to operate. At the same time, the buttons are greatly affected by water pressure, and the structure is complex. This is especially true for shower diverter valves, where push-button switching requires many valve cores, resulting in high costs. Furthermore, the separate design of multiple buttons and flow control knobs leads to a poor user experience. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide a multi-functional switching valve, specifically through structural design that integrates buttons to enhance the user experience.

[0004] This invention is achieved through the following technical solution:

[0005] A multifunctional switching valve includes a valve body, a fixed slider with a groove, and a switching rod connected to the fixed slider. A spring is provided between the switching rod and the fixed slider. The switching rod can pass through the groove and engage with the fixed slider, and can move within the groove. A button is connected to the switching rod. The fixed slider has a first oblique surface, and the switching rod has a second oblique surface that engages with the first oblique surface. The fixed slider also has a slot for engaging the switching rod. The engagement of the first oblique surface of the fixed slider with the second oblique surface of the switching rod determines the opening and closing of the water passage. The valve body has at least one water passage.

[0006] In this embodiment of the invention, the first beveled surface is disposed opposite to the slot.

[0007] In this embodiment of the invention, the valve body is provided with three water passages, and correspondingly provided with three switching rods and three fixed sliders, with a paired spring between each of the three switching rods and the three fixed sliders.

[0008] In this embodiment of the invention, three fixed sliders interact with each other, and the end of the fixed slider near the first oblique surface is triangular-pointed.

[0009] In this embodiment of the invention, the valve body further includes a water distribution body, on which a water outlet with a water passage is provided. The three water passages are respectively provided with a first water outlet, a second water outlet, and a third water outlet, and the first water outlet, the second water outlet, and the third water outlet are distributed in a stepped manner.

[0010] In Embodiment 2 of the present invention, the valve body is provided with two water passages, and correspondingly there are two switching rods and two fixed sliders. Each of the two switching rods and the two fixed sliders is provided with a paired spring. The shower device is provided with a first water outlet and a second water outlet corresponding to the two water passages.

[0011] In this embodiment, the two fixed sliders interact with each other, and the end of the fixed slider closest to the first oblique surface is the end of mutual pushing action.

[0012] In this embodiment, the valve body further includes a water distribution body, on which a water outlet with a water passage is provided. The two water passages are respectively provided with a first water outlet and a second water outlet, and the first water outlet and the second water outlet are distributed in a stepped manner.

[0013] In this embodiment of the invention, the water divider is also connected to a water divider cover.

[0014] In this embodiment of the invention, a fixed plate is also provided in the valve body, and a knob is connected to the fixed plate. The knob can drive the fixed plate to rotate and change its relative position with the valve body to change the water inlet volume.

[0015] In this embodiment of the invention, a limit block is provided on the fixed disk.

[0016] In this embodiment of the invention, the multi-functional switching valve is also applied to a shower device. The shower device is provided with a water outlet channel that matches the three water passages. The multi-functional control valve is provided with three paired switching rods and fixed sliders. The three fixed sliders interact with each other, so that pressing a button pushes one of the fixed sliders, which in turn drives the movement of the other two sliders, causing the switching rod corresponding to the pushed slider to reset and seal the water under the action of the spring.

[0017] The multifunctional switching valve of the present invention has the following beneficial effects:

[0018] The valve body is equipped with a fixed slide block, which works in conjunction with the connecting switching rod, button and spring. Under the action of the first and second oblique surfaces and the interaction between the three fixed sliders, the button of the present invention is integrated, which also avoids multiple valve core designs and reduces production costs.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0034] Referring to the accompanying drawings, a multi-functional switching valve includes a valve body 100. A fixed slider 10 is disposed within the valve body 100. The fixed slider 10 has a sliding groove 11. A switching rod 20 is also connected to the fixed slider 10. A spring 30 is disposed between the switching rod 20 and the fixed slider 10. The switching rod 20 can pass through the sliding groove 11 and engage with the fixed slider 10. The switching rod 20 can move within the sliding groove 11. A button 40 is connected to the switching rod 20. The fixed slider 10 has a first oblique surface 16. The switching rod 20 has a second oblique surface 26 that engages with the first oblique surface 16. The fixed slider 10 also has a slot 12 for engaging the switching rod 20. The engagement of the first oblique surface 16 of the fixed slider 10 with the second oblique surface 26 of the switching rod 20 determines the opening and closing of the water passage. The valve body 100 is provided with at least one water passage. More specifically, in this embodiment of the invention, the valve body 100 is provided with three water passages, and correspondingly, three switching rods and three fixed sliders are provided. Each of the three switching rods and the three fixed sliders is provided with a paired spring. In this embodiment, these are the first switching rod 61, the second switching rod 62, the third switching rod 63, the first fixed slider 51, the second fixed slider 52, the third fixed slider 53, the first spring 71, the second spring 72, and the third spring 73. The three fixed sliders interact with each other. The end of the fixed slider 10 near the first oblique surface 16 is triangular-pointed. (Refer to the attached specification.) Figure 5 As shown, one end of the triangular tip of the first fixed slider is connected to one end of the triangular tip of the second slider, and the other end of the triangular tip of the first fixed slider is connected to one end of the triangular tip of the third slider. Similarly, the other end of the second fixed slider is engaged with the other end of the third fixed slider. This structure enables the other two fixed sliders to slide under the push of the slider when the user presses button 40 to operate one of the switching rods and fixed sliders. This causes the switching rod corresponding to the pushed slider to reset and seal the water under the action of the spring. Through the integration of the above structure, this invention realizes the control of water outlet from multiple water passages, avoids the independent setting of multiple valve cores and switches, greatly reduces production costs, and enhances the user experience.

[0035] Furthermore, the first oblique surface 16 is positioned opposite to the slot 12.

[0036] Furthermore, the valve body 100 also includes a water distribution body 80, which has water outlets with water passages. The three water passages are respectively provided with a first water outlet 81, a second water outlet 82, and a third water outlet 83. The first water outlet 81, the second water outlet 82, and the third water outlet 83 are arranged in a stepped distribution. (Refer to the appendix of the instruction manual.) Figure 4 , 6 As shown in Figures 7 and 8, its purpose is to facilitate the manufacturer's processing and assembly during production.

[0037] The accompanying drawings of this invention only show a schematic diagram of three water passages. Of course, the number of water passages, switching rods, fixed sliders, and springs can be increased according to the needs of the shower device. For example, in embodiment 2, the valve body is provided with two water passages, corresponding to two switching rods and two fixed sliders. Each of the two switching rods and two fixed sliders is equipped with a paired spring. The shower device is provided with a first water outlet and a second water outlet corresponding to the two water passages. In this embodiment, the two fixed sliders interact with each other, with the end of the fixed slider near the first oblique surface being the mutual pushing end.

[0038] In this embodiment, the valve body further includes a water distribution body, on which a water outlet with a water passage is provided. The two water passages are respectively provided with a first water outlet and a second water outlet, and the first water outlet and the second water outlet are distributed in a stepped manner.

[0039] Furthermore, the water distribution body 80 is also connected to a water distribution cover 90.

[0040] Furthermore, a fixed plate 200 is also provided inside the valve body 100. The fixed plate 200 is connected to a knob 210. The knob 210 can drive the fixed plate 200 to rotate and change its relative position with the valve body 100 to change the water inflow. Specifically, the flow rate is controlled by changing the water passage area between the fixed plate 200 and the valve body 100. More specifically, a limit block 201 is provided on the fixed plate 200. The purpose of the limit block 201 is to limit the flow rate when the knob 210 adjusts the fixed plate 200.

[0041] In use, the multi-functional switching valve is also applied to a shower device. The shower device has three water outlet channels matching the three water passages. In a conventional embodiment, these water outlet channels are the overhead spray channel, the shower head channel, and the drain pipe channel. The multi-functional switching valve is equipped with three paired switching rods and fixed sliders. The three fixed sliders interact with each other, so that pressing a button pushes one of the fixed sliders, which in turn moves the other two sliders, causing the switching rod corresponding to the pushed slider to reset and seal the water flow under spring action. Of course, in a preferred embodiment of the invention, an embodiment with a fixed disc and knob for adjusting the water inlet flow is provided, as well as an embodiment where the water inlet flow cannot be adjusted, depending on customer and market needs. More specifically, the user presses button 40 to move the switching rod 20. During the movement of the switching rod 20, its second oblique surface 26 engages with the first oblique surface 16 on the fixed slider 10, thereby achieving a clearance function, causing the switching rod 20 to engage with the slot 12 on the fixed slider 10, thus achieving the water outlet function of the water passage. (Refer to the attached instruction manual.) Figure 4 and 6 As shown, due to the interaction of the three fixed sliders, when one fixed slider is activated, it will act on the other two fixed sliders, thereby causing the other two fixed sliders to slide. In turn, these two sliders will drive their corresponding switching rods to move. Under the action of their respective springs, the other two water passages achieve the function of resetting and sealing the water.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
