[0029] like Figure 1-3 As shown, an anti-stuck drain device includes a drain pipe 1, the outside of the drain pipe 1 is provided with an external thread, the drain pipe 1 is a tubular structure with a hollow interior, the interior of the drain pipe 1 is fixedly installed with a core bracket 2, the core bracket 2 is installed on the core 3, the core 3 is installed inverted, the top of the core 3 extends to the top of the drain pipe 1, the top of the drain pipe 1 is provided with an upper blocking plate 4, the upper blocking plate 4 and the drain pipe 1 are integrally formed, a sealing cover plate 5 is installed above the upper blocking plate 4, the sealing cover plate 5 is connected to the core 3, the bottom of the sealing cover plate 5 is fixedly provided with a sealing ring 6, the sealing ring 6 covers the water inlet of the upper blocking plate 4 when the sealing cover plate 5 moves up and down, and the diameter of the sealing ring 6 is larger than the diameter of the inner tube of the drain pipe 1.
[0030] In this embodiment, the end with a smaller diameter of the movement 3 is installed inside the sewer pipe 1, while the end with a larger diameter of the movement 3 is connected to the sealing cover plate 5. This will not occupy the flow space of the sewer, thereby expanding the water flow space and increasing the drainage volume, making it less likely to cause blockage.
[0031] Combine Figure 3 As shown, the inner wall of the sewer pipe 1 is provided with a mounting convex ring 7, and a mounting portion 8 is provided on the central axis of the mounting convex ring 7. The outer wall of the mounting portion 8 is fixedly connected to the inner wall of the mounting convex ring 7 through three groups of support rods 9, and a sewer hole is formed between the mounting portion 8 and the mounting convex ring 7.
[0032] In this embodiment, the mounting portion 8 , the support rod 9 and the mounting protruding ring 7 constitute the movement bracket 2 , which can fix the movement 3 .
[0033] Combine Figure 3 、 Figure 4 、 Figure 7 As shown, a threaded mounting hole is provided on the inner ring of the mounting portion 8, a lower connecting portion 10 is provided at the bottom end of the movement 3, and the bottom end of the movement 3 is fixed to the mounting hole of the mounting portion 8 by a threaded connection.
[0034] The bottom of the sealing cover plate 5 is integrally formed with a connection hole 12 , and the top of the movement 3 is provided with an upper connection portion 11 , which is threadedly connected to the upper blocking plate 4 in a threaded connection manner.
[0035] In this embodiment, both ends of the core 3 are connected to the downpipe 1 and the sealing cover plate 5 respectively by threaded connection, which makes assembly and disassembly convenient.
[0036] Combine Figure 5 、 Figure 6 As shown, a tubular mounting member 13 extends downward from the bottom of the upper blocking plate 4 , an annular mounting groove 14 is provided on the outer wall of the tubular mounting member 13 , and the sealing ring 6 is fixedly mounted in the annular mounting groove 14 of the tubular mounting member 13 .
[0037] In this embodiment, when the sealing cover plate 5 is pressed downward, the sealing ring 6 directly covers the water inlet of the sewer pipe 1 without blocking the sewer pipe 1. In this way, even if the sealing ring 6 ages, it will not block the sewer pipe 1, thereby avoiding the phenomenon that the movement cannot bounce up.
[0038] Combine Figure 1 、 Figure 2 As shown, the outer portion of the sewer pipe 1 is sequentially sleeved with an upper seal 15 , a lower seal 16 and a locking nut 17 from top to bottom, and the locking nut 17 is threadedly connected to the inner wall of the sewer pipe 1 .
[0039] In this embodiment, the upper seal 15 is located inside the wash basin, and the lower seal 16 is located at the bottom of the wash basin. Then, the locking nut 17 is tightened with a wrench, and the locking nut 17 squeezes the upper seal 15 and the lower seal 16, thereby achieving a sealing and waterproofing effect.
[0040] Combine Figure 1 、 Figure 3 As shown, the upper sealing member 15 and the lower sealing member 16 adopt a trumpet-shaped structure.
[0041] In this embodiment, the upper sealing member 15 and the lower sealing member 16 can improve the sealing effect.
[0042] Combine Figure 4 、 Figure 5 As shown, the sealing ring 6 is an inverted frustum-shaped structure, and the sealing ring 6 is made of rubber material.
[0043] In this embodiment, the sealing ring 6 directly covers the water inlet of the sewer pipe 1 without blocking the sewer pipe 1. In this way, even if the sealing ring 6 ages, it will not block the sewer pipe 1, avoiding the phenomenon that the movement cannot bounce up.
[0044] Combine Figure 1 、 Figure 3 As shown, overflow holes 18 are opened on both side walls of the sewer pipe 1 close to the upper blocking plate 4 , and the overflow holes 18 are communicated with the sewer pipe 1 .
[0045] In this embodiment, when the wash basin is full of water, the overflow hole 18 flows through the holes on the wash basin and then enters the drain pipe 1 through the overflow hole 18 .
[0046] Combine Figure 7 As shown, the movement 3 adopts a two-stage bouncing movement, the material of the movement 3 is brass, and the sewer pipe 1 and the sealing cover plate 5 are made of stainless steel.
[0047] In this embodiment, brass has strong wear resistance and high corrosion resistance, and can resist the erosion of many chemical substances. The sewer pipe 1 and the sealing cover plate 5 are made of stainless steel, which has outstanding corrosion resistance and certain chemical corrosion resistance.
[0048] The working principle of this utility model is:
[0049] Since the movement used in the current drain device is installed upright, the bottom of the movement is larger and the top of the movement is smaller. The bottom end of the upright installation movement is installed inside the drain pipe 1. Since the bottom of the movement occupies a larger space in the drain pipe 1, the water flow space is larger, so it is easy to get blocked during the downward flow of water. The utility model changes the traditional upright installation to an inverted installation, so that the end with the smaller diameter of the movement 3 is installed inside the drain pipe 1, and the end with the larger diameter of the movement 3 is connected to the sealing cover plate 5, which does not occupy the flow space of the sewer, thereby expanding the water flow space and increasing the drainage volume, making it less likely to get blocked.
[0050] At the same time, since the outer diameter of the current sealing ring 6 is equal to the inner diameter of the sewer pipe 1, when the sealing cover plate 5 is pressed downward, the sealing ring 6 is directly blocked into the inside of the sewer pipe 1, which is to improve the sealing performance. However, due to aging of the sealing ring 6 or obstruction of foreign matter, the movement 3 often cannot pop out the sealing ring 6. The diameter of the sealing ring 6 of the utility model is larger than the diameter of the inner tube of the sewer pipe 1. In this way, when the sealing cover plate 5 is pressed downward, the sealing ring 6 directly covers the water inlet of the sewer pipe 1 without being blocked into the sewer pipe 1. In this way, even if the sealing ring 6 ages, it will not block the sewer pipe 1, thereby avoiding the phenomenon that the movement cannot bounce up.
[0051] When installing the present invention, the sewer pipe 1 is installed in the hole of the wash basin, the upper seal 15 is located inside the wash basin, and the lower seal 16 is located at the bottom of the wash basin. Then, the locking nut 17 is tightened with a wrench, and the locking nut 17 squeezes the upper seal 15 and the lower seal 16, thereby achieving a sealing and waterproofing effect. When in use, the sealing cover plate 5 is pressed downward. At this time, the sealing ring 6 blocks the sewer pipe 1 to prevent water flow. Then, the sealing cover plate 5 is pressed again, and the movement 3 pops up the sealing cover plate 5, and the sealing ring 6 moves upward together. At this time, the water inlet of the sewer pipe 1 is opened, thereby draining the water in the wash basin.
[0052] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the spirit of the present invention.
