Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, and in particular to a flow-increasing drainage valve. Background Art

[0002] In the sanitary ware industry, the drain valve inside the toilet and wall-mounted water tank is a key component responsible for flushing the waste into the sewer. The performance of the drain valve is directly related to whether it can be flushed cleanly and whether it saves water and energy. The quality of the flushing effect depends largely on the drainage flow rate. For the same amount of water, if the drainage rate increases, it can form a greater flushing pressure, thereby producing a stronger siphon effect.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figures 1 to 3 A flow-increasing drainage valve of the present invention comprises: a drainage body 100, wherein the drainage body 100 has a vertically extending drainage channel 110; a switch member 200, which is movably connected to the drainage body 100, and the switch member 200 has a sealing sheet 210 capable of opening or closing the upper port of the drainage channel 110; a guide member 300, which is arranged on the switch member 200, is located below the sealing sheet 210, and has a plurality of guide grooves distributed at intervals around an axis, wherein the guide grooves are used to drive water to produce a rotating downward movement to increase the water flow rate.

[0032] The flow-increasing drainage valve of the above structure is provided with a flow guide 300 below the sealing sheet 210. When the sealing sheet 210 opens the upper port of the drainage channel 110, as shown in FIG. Figure 2The arrowed line segments shown are water flow path diagrams, and water rushes into the guide member 300 from all directions, causing the water flow to change from an irregular and chaotic state to a regularly rotating downward vortex. At the same time, the center of the vortex is usually a through hole without water flow to destroy the effect of local vacuum adsorption. Thus, the vortex speed-increasing effect of the multiple guide grooves of the guide member 300 ultimately increases the water flow speed, thereby achieving an increased drainage speed. Therefore, when sanitary ware adopts the flow-increasing drainage valve of the present invention, the sanitary ware can be flushed with a higher speed of water at the moment of flushing, thereby improving the flushing effect of the sanitary ware, reducing the water flow required for flushing, and achieving water saving.

[0033] See also Figure 3 Or see Figure 6 In some embodiments of the present invention, the guide member 300 includes a shaft member 310 and a plurality of guide plates 320 spaced apart on the outer peripheral wall of the shaft member 310, and a guide groove is defined between two adjacent guide plates 320 and the outer peripheral wall of the shaft member 310, and the guide groove is spirally arranged in a clockwise or counterclockwise direction around the axis of the shaft member 310. The spiral directions of all guide grooves are consistent, and the spirally arranged guide grooves are conducive to guiding the water flow to form a spiral downward movement. The structure of arranging the guide plate 320 on the shaft member 310 is conducive to processing and manufacturing, and is also conducive to strictly controlling the depth dimension of the guide groove along its extension direction, thereby helping to adjust the ideal state of the water flow shock wave. Specifically, in this embodiment, the spiral guide groove is less than one circle, and the angular displacement generated when the water flow passes through the guide groove is small, which is conducive to the water flow maintaining a large kinetic energy and impacting downward.

[0034] It should be noted that, in other embodiments, the guide groove can also be arranged in a straight line, and the guide groove is inclined relative to the axis of the shaft 310, so that the guide groove can also guide the water flow passing through the guide groove to form a rotating downward vortex. Of course, in other embodiments, the guide groove can also be formed by being concave along the outer peripheral wall of the shaft 310, such as by integral stamping or integral injection molding.

[0035] See also Figure 5 and Figure 6 In some embodiments of the present invention, the shaft 310 is in the shape of a long frustum with a larger top and a smaller bottom. Figure 6 The arrowed line segment shown is a water flow path diagram. Water entering the guide groove is limited by the two adjacent guide plates 320 and the outer surface of the shaft 310. The outer surface of the shaft 310 is a frustum, which can guide the water to converge toward the axial position close to the shaft 310, thereby forming a downward impact water flow, further increasing the water flushing pressure.

[0036] In some other embodiments, the shaft member 310 is not limited to a long truncated cone shape with a larger top and a smaller bottom, and the distance between the bottom wall of the guide groove and the axis of the shaft member 310 gradually decreases along the drainage direction of the guide groove. According to the principle of fluid mechanics, the vortex formed by the water flow passing through the guide member 300 has a diameter that gradually decreases downward along the drainage channel 110. By setting the distance between the bottom wall of the guide groove and the axis of the shaft member 310 to gradually decrease along the drainage direction of the guide groove, the depth size of the guide groove adapts to the change in the diameter of the vortex, so that the guide groove can better guide the water flow to form a vortex, thereby further improving the drainage speed.

[0037] See also Figure 3 Or see Figure 6 In some embodiments of the present invention, the guide plate 320 is bent around the shaft 310 in a clockwise or counterclockwise direction, and the angle between the guide plate 320 and the outer peripheral wall of the shaft 310 gradually decreases from bottom to top, that is, when water enters the upper end of the guide groove, a large angular displacement is generated. As the water flows to the lower end of the guide groove, the water in each guide groove has a large flow velocity along the length direction of the shaft 310, which is conducive to forming a shock wave converging downward, and the shock wave also has a movement tendency of multiple streams of water spiraling around.

[0038] See also Figure 2 and Figure 3 In some embodiments of the present invention, the guide member 300 is connected to the switch member 200 by rotating around the axis. It can be understood that when the guide plate 320 is arranged in a clockwise or counterclockwise spiral around the axis of the shaft member 310, water flows from all directions to the guide member 300 and enters the guide groove to form a rotation effect. At this time, the guide member 300 also has a relative rotation movement trend. The rotation of the guide member 300 relative to the switch member 200 can reduce the kinetic energy loss of the water flow and ensure the impact force of the water flow.

[0039] Moreover, in this embodiment, in order to realize that water can flow from all directions to the upper port of the drainage channel 110 when the switch member 200 rises, the drainage body 100 has a frame surrounding the outer periphery of the switch member 200 and the guide member 300, and a plurality of columns are arranged at intervals in the frame, and water inlets are formed between adjacent columns, so that water can enter the drainage channel 110 from water inlets in different directions. Since the guide member 300 can rotate relative to the switch member 200, the side opening of the guide groove can be rotated to face any water inlet, thereby avoiding that part of the guide groove always faces the column and affects the water inlet, and further improves the drainage uniformity.

[0040] See also Figure 2 and Figure 3In some embodiments of the present invention, in some embodiments of the present invention, the switch member 200 includes a vertically arranged connecting rod 220, the sealing sheet 210 is installed at the lower part of the connecting rod 220, and the lower end of the connecting rod 220 is provided with a pivot 230, and the lower end of the pivot 230 has two anti-detachment hooks 231 arranged opposite to each other and capable of elastic deformation along the radial direction of the pivot 230, and the guide member 300 is provided with an axial hole 311 for the pivot 230 and the anti-detachment hook 231 after elastic deformation to pass through, and a limiting ring 312 is provided in the axial hole 311 corresponding to the anti-detachment hook 231. It can be understood that the aperture of the shaft hole 311 is adapted to the diameter of the pivot 230. Generally speaking, the connecting rod 220, the pivot 230 and the guide member 300 are all made of plastic material. During assembly, force is applied to the two anti-detachment hooks 231 to drive the two to approach each other. At this time, the pivot 230 and the anti-detachment hook 231 can pass through the shaft hole 311. When the anti-detachment hook 231 passes over the limiting ring 312, it restores its elastic deformation and prevents the guide member 300 from downwardly separating from the pivot 230, thereby realizing the function of the guide member 300 rotating relative to the switch member 200 with a simple structure.

[0041] Specifically, the connecting rod 220 includes a sleeve 221 and a column 222 inserted at the lower end of the sleeve 221, the pivot 230 is formed at the lower end of the column 222, an umbrella-shaped tray 240 is formed on the periphery of the column 222, a cover plate 250 located above the umbrella-shaped tray 240 is penetrated through the periphery of the column 222, and the lower end of the sleeve 221 presses downward against the cover plate 250 to clamp the sealing sheet 210 between the cover plate 250 and the umbrella-shaped tray 240. Specifically, a notch is provided on the side wall of the sleeve 221, and a hook that can be elastically engaged in the notch is provided on the upper part of the column 222. The cover plate 250 and the sealing sheet 210 are in the shape of an annulus. During assembly, after the above-mentioned guide member 300 is rotatably connected to the pivot 230, the sealing sheet 210 is inserted into the column 222 and abutted against the umbrella-shaped tray 240, and then the cover plate 250 is inserted into the column 222 and abutted against the sealing sheet 210. When the column 222 is inserted into the sleeve 221 so that the hook is engaged in the notch, the sealing sheet 210 is clamped and fixed.

[0042] In the prior art, the size of a conventional drain valve is usually 2 inches or 3 inches, and the outer diameter of the drain channel 110 is 2 inches or 3 inches. In some embodiments of the present invention, the outer diameter of the lower end of the drain body 100 is 2 inches or 3 inches, so as to be compatible with the installation structure of existing sanitary ware products. Of course, it is conceivable that the flow-increasing drain valve provided by the present invention can also be set to other sizes according to actual needs.

[0043] See also Figure 5In some embodiments of the present invention, the switch member 200 includes a float 260 rotatably connected to the drainage body 100 around a horizontal axis, the sealing sheet 210 is installed on the lower end surface of the float 260, the middle of the float 260 is connected with a mounting seat 270 for clamping the sealing sheet 210, and the flow guide 300 is installed on the mounting seat 270, or the flow guide 300 is integrally formed on the mounting seat 270. That is, the flow guide 300 can be installed on both the cylindrical drainage valve and the float 260 drainage valve, which widens the scope of application.
