AI Technical Summary
The drainage passage of the existing toilet tank drain valve cannot be filled with water, resulting in slowing down the drainage speed.
At the end of the drainage channel, an annular water guide surface extending radially outward and a water barrier extending upward in the vertical direction are provided to increase the offset and buffering of the water flow direction, reduce air gaps, and improve water filling.
Through the design of annular water guide surface and water barrier, the water flow can maximize the drainage passage, significantly increasing the drainage speed.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drain valves, and in particular relates to a drain valve base capable of improving drainage speed. Background Art
[0002] Existing toilet tank flap drain valves usually include a base with a drainage channel, the bottom of the base is sealed and connected to the bottom of the water tank, such as Figure 1 As shown, when the drain valve drains water, there is a large air gap A around the drainage channel wall of the base, which causes the drainage channel to be unable to be filled with water. Water only flows out through the central area of the drainage channel, reducing the drainage speed. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art described in the background technology, the utility model provides a drain valve base that improves drainage speed, characterized in that it includes a seat body, the seat body has a drainage channel running through from top to bottom, the end of the drainage channel is provided with an annular water guide surface extending radially outward, and the edge of the annular water guide surface is provided with a water baffle extending upward in a vertical direction.
[0004] Furthermore, the width of the annular water guide surface is greater than 5 mm.
[0005] Furthermore, an end portion of the water baffle is higher than an end portion of the drainage channel.
[0006] Furthermore, the height of the water baffle is not greater than 20 mm.
[0007] Compared with the background technology, the technical solution adopted by the present invention has the following advantages:
[0008] By arranging an annular water guide surface and a water baffle at the water inlet end of the drainage channel, water can fill the drainage channel to the maximum extent when the drainage valve base drains water, thereby improving the drainage speed. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 A schematic diagram of a drainage cross-section of a flap drain valve base structure in the prior art;
[0010] Figure 2 This is a schematic diagram of the structure of the drain valve base of the utility model;
[0011] Figure 3 This is a schematic drainage cross-sectional view of the drainage valve base structure of the present utility model. DETAILED DESCRIPTION
[0012] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.
[0013] like Figure 2-3 As shown, the drain valve base for improving drainage speed of the utility model includes a seat body 1, the seat body 1 has a drainage channel 11 running through the upper and lower parts, the seat body 1 is sealed and fixed to the bottom surface of the toilet tank, and the drain valve also has a water-stop rubber pad for opening or closing the drainage channel 11, which is used to realize water tank drainage. This prior art will not be described in detail.
[0014] An annular water guide surface 12 extending radially outward is provided at the end of the drainage channel 11 , and the edge of the annular water guide surface 12 extends upward in the vertical direction to form an annular water baffle 13 , and the end of the water baffle 13 is higher than the end of the drainage channel 11 .
[0015] When the drain valve drains water, water from the outer periphery of the seat body 1 flows in through the end of the water deflector 13. This water flow exerts a force horizontally toward the center of the seat body 1. Because the annular water guide surface 12 is located below the end of the water deflector 13, the water flows downward into the annular water guide surface 12, causing the water flow to shift vertically. After being buffered by the annular water guide surface 12, the force of the water flowing toward the center of the seat body 1 is weakened, and the water then flows into the drain channel 11 of the seat body 1. Meanwhile, the water flowing directly above the drain channel 11 flows essentially vertically downward, exerting a force that forces the water to flow vertically downward. This water flow merges with the water flowing from the outer periphery of the seat body 1 and is discharged from the drain channel 11. The arrangement of the water deflector 13 and the annular water guide surface 12 deflects the water flow vertically and weakens the force of the water flowing from the outer periphery of the seat body 1 toward the center of the seat body 1. This reduces the air gap B around the wall of the drain channel 11, allowing the water to fill the drain channel 11 to the maximum extent possible, thereby increasing the drainage speed.
[0016] The width of the preferred annular water guide surface is greater than 5 mm, so that after being buffered by the annular water guide surface 12, the force of water flowing toward the center of the seat body 1 is weakened; and the height of the water baffle is not greater than 20 mm, so that the water in the water tank can be discharged as much as possible while increasing the drainage speed.
[0017] The above describes in detail the drain valve base for improving drainage speed provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
