[0031] Referring to Figures 1 to 3 The utility model discloses a flow increasing drain valve, which comprises a drain main body 100, the drain main body 100 has vertically extending drain passage 110, switch piece 200 is movably connected to the drain main body 100, the switch piece 200 has the sealing sheet 210 that can open or close the upper port of the drain passage 110, the flow guide piece 300 is arranged on the switch piece 200 and is located below the sealing sheet 210, a plurality of flow guide grooves are distributed around an axis, and the flow guide grooves are used to drive water to rotate downward to increase the water flow speed.
[0032] The flow increasing drain valve with the above structure is provided with the flow guide piece 300 below the sealing sheet 210, when the sealing sheet 210 opens the upper port of the drain passage 110, Figure 2The arrowed line segment shown is a water flow path diagram, water flows from all directions to the flow guide 300, so that the water flow changes from an irregular turbulent state to a regular downward rotating vortex, and the center of the vortex is usually a through hole without water flow to destroy the effect of local vacuum adsorption, thereby, the vortex speed of the multiple flow guide grooves of the flow guide 300 is increased, finally the water flow speed is increased, the speed of the drainage is improved, and when the bathroom sanitary ware adopts the flow increasing drainage valve, the bathroom sanitary ware can flush with a higher speed of water flow in the flushing moment, the flushing effect of the bathroom sanitary ware is improved, the water flow required for flushing is reduced, and water saving is achieved.
[0033] Referring to Figure 3 or referring to Figure 6 In some embodiments of the utility model, the flow guide 300 includes a shaft 310 and multiple flow guide plates 320 which are arranged at intervals on the outer peripheral wall of the shaft 310, an adjacent two flow guide plates 320 and the outer peripheral wall of the shaft 310 define a flow guide groove, and the flow guide grooves are arranged spirally in the clockwise or counterclockwise direction around the axis of the shaft 310. The spiral directions of all the flow guide grooves are consistent, and the spirally arranged flow guide grooves are beneficial to guiding the water flow to form a spiral downward movement. The structure of arranging the flow guide plates 320 on the shaft 310 is beneficial to processing and manufacturing, and is also beneficial to strictly controlling the depth dimension of the flow guide grooves along the extension direction, thereby helping to adjust the water flow impact wave to an ideal state. Specifically, in the embodiment, the spiral flow guide grooves are less than one turn, the angular displacement of the water flow passing through the flow guide grooves is small, and the water flow is beneficial to maintaining a large kinetic energy to impact downward.
[0034] It should be noted that in other embodiments, the flow guide grooves can also be arranged in a straight line and inclined relative to the axis of the shaft 310, so that the flow guide grooves can also guide the water flow passing through the flow guide grooves to form a downward rotating vortex. Of course, in other embodiments, the flow guide grooves can also be recessed along the outer peripheral wall of the shaft 310, for example, in the form of one-piece stamping or one-piece injection molding.
[0035] Referring to Figure 5 and Figure 6 In some embodiments of the utility model, the shaft 310 is in the shape of a long strip of a circular truncated cone type with a large upper part and a small lower part. It can be understood that, as Figure 6 The arrowed line segment shown is a water flow path diagram, water entering the flow guide groove is limited by the adjacent two flow guide plates 320 and also limited by the outer peripheral surface of the shaft 310, and the outer peripheral surface of the shaft 310 in the shape of a circular truncated cone can guide the water to converge towards the position close to the axis of the shaft 310, thereby forming a downward impacting water flow, and further improving the water flow flushing pressure.
[0036] In some other embodiments, the shaft 310 is not limited to the long strip-shaped circular truncated cone type with the upper part being larger and the lower part being smaller, and the spacing between the bottom wall of the flow guide groove and the axis of the shaft 310 gradually decreases along the drainage direction of the flow guide groove. According to the principle of fluid mechanics, the vortex formed by the water flow passing through the flow guide 300 gradually decreases in diameter downward along the drainage channel 110, and by gradually decreasing the spacing between the bottom wall of the flow guide groove and the axis of the shaft 310 along the drainage direction of the flow guide groove, the depth dimension of the flow guide groove is adapted to the change in the diameter of the vortex, so that the flow guide groove can better guide the water flow to form a vortex, thereby further improving the drainage speed.
[0037] Referring to Figure 3 or referring to Figure 6 In some embodiments of the present application, the flow guide plate 320 is bent in the clockwise or counterclockwise direction around the shaft 310, and the included angle between the flow guide plate 320 and the outer peripheral wall of the shaft 310 gradually decreases from bottom to top, that is, when the water enters the upper end of the flow guide groove, a larger angular displacement is generated, and as the water flows to the lower end of the flow guide groove, the flow velocity of the water in each flow guide groove along the length direction of the shaft 310 is larger, which is beneficial to form a downward converging shock wave, and the shock wave also has a motion trend of spiral wrapping of multiple water flows.
[0038] Referring to Figure 2 and Figure 3 In some embodiments of the present application, the flow guide 300 is rotationally connected to the switch 200 around the axis. It can be understood that in the case of the flow guide plate 320 being spirally arranged in the clockwise or counterclockwise direction around the axis of the shaft 310, the water from all directions rushes to the flow guide 300 and enters the flow guide groove, forming a rotating effect, at this time the flow guide 300 also has a motion trend of relative rotation, and the relative rotation of the flow guide 300 with respect to the switch 200 can reduce the kinetic energy loss of the water flow and protect the water flow impact force.
[0039] Moreover, in the present embodiment, in order to realize that when the switch 200 rises, water can rush to the upper port of the drainage channel 110 from all directions, the drainage main body 100 has a frame body surrounding the outer periphery of the switch 200 and the flow guide 300, a plurality of columns are arranged at intervals in the frame body, and water inlet ports are formed between adjacent columns, and water can enter the drainage channel 110 from different water inlet ports. Since the flow guide 300 can rotate relative to the switch 200, the side opening of the flow guide groove can be rotated to face any water inlet port, avoiding that part of the flow guide grooves always face the columns to affect the water inflow, and further improving the drainage uniformity.

[0041] Specifically, the connecting rod 220 includes a sleeve 221 and a plug 222 inserted into the lower end of the sleeve 221, the pivot 230 is formed at the lower end of the plug 222, the outer periphery of the plug 222 is formed with an umbrella-shaped tray 240, the outer periphery of the plug 222 is provided with a cover plate 250 located above the umbrella-shaped tray 240, and the lower end of the sleeve 221 abuts against the cover plate 250 to clamp the sealing sheet 210 between the cover plate 250 and the umbrella-shaped tray 240. Specifically, the side wall of the sleeve 221 is provided with a notch portion, the upper part of the plug 222 is provided with a hook capable of being elastically clamped in the notch portion, the cover plate 250 and the sealing sheet 210 are annular, and when assembling, after the flow guide piece 300 is rotationally connected to the pivot 230, the sealing sheet 210 is inserted into the plug 222 and abuts against the umbrella-shaped tray 240, then the cover plate 250 is inserted into the plug 222 and abuts against the sealing sheet 210, and when the plug 222 is inserted into the sleeve 221 to enable the hook to be clamped in the notch portion, the sealing sheet 210 is clamped and fixed.
