Description

Technical Field

[0001] The utility model relates to the technical field of wall drainage, and particularly relates to a rainwater funnel for wall drainage with sealing performance. Background Art

[0002] The gutter often has side drainage or external drainage, and the water discharges through the wall and is externally connected to the downpipe. The commonly used wall drainage elbow is a 90° PVC or metal elbow connected to the external downpipe for drainage. However, this elbow does not have a sealing function, often causing water to overflow and flow back to the wall, resulting in "water leakage" on the outer wall. Summary of the Invention

[0006] Preferably, the other sides of the rainwater funnel body except the side close to the wall are wavy.

[0007] Preferably, the filter screen is detachable.

[0008] Preferably, the sealing structure includes a sealing groove and a sealing ring, and the sealing ring is installed in the sealing groove.

[0009] Preferably, the lining seal is provided with two parallel sealing grooves and sealing rings.

[0010] Preferably, the lining seal is made of stainless steel or other materials that are not easy to rust.

[0011] Preferably, the lining seal and the rainwater funnel are connected by welding or threading.

[0012] Preferably, an inclined surface is formed along the circumferential direction of the inner diameter edge of the lining seal.

[0013] The advantages of the utility model are: using a sealed rainwater bucket to solve the problem of conventional elbow leakage; and solving the problem that the rainwater bucket is easily detached due to rapid water outflow. The utility model can handle large-volume flushing, and at the same time, a filter is added on the top, which is not easy to be blocked. The side drainage saves the elbow accessories and is directly connected to the rainwater bucket, which is beautiful in appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1 to 4As shown in the figure, a wall-mounted sealed rainwater bucket 100 includes: a rainwater bucket body 1. A water inlet is provided at the top of the rainwater bucket body 1. A filter screen 3 that matches its size is provided near the water inlet. An interface for connecting a downpipe 300 is provided at the bottom of the rainwater bucket body 1. A circular opening is provided on the side of the rainwater bucket body against the wall and below the filter screen 3, and the inner diameter of the circular opening is larger than the outer diameter of the drain pipe in the wall; a lining seal 2 is provided in the circular opening of the rainwater bucket body 1, its outer diameter matches the inner diameter of the circular opening, and its inner diameter matches the outer diameter of the inner drain pipe 200; and at least one sealing structure 4 is also provided on the side of the lining seal 2 in contact with the outer wall of the drain pipe 200 in the wall; a threaded hole 5 is also opened at the top of the lining seal 2 near the circular interface, and the threaded hole 5 is located behind the sealing structure 4, and the lining seal 2 is fixedly connected to the drain pipe 200 in the wall by screwing a screw (as Figure 4 shown).

[0023] Preferably, the other sides of the rainwater bucket body 1 except the side against the wall are wavy (as Figure 3 shown).

[0024] Preferably, the filter screen 3 is detachable.

[0025] Preferably, the sealing structure 4 includes a sealing groove 41 and a sealing ring 42, and the sealing ring 41 is installed in the sealing groove 42 (as Figure 4 shown).

[0026] Preferably, the lining seal 2 is provided with two parallel sealing grooves 41 and sealing rings 42 (as Figure 4 shown). The first sealing ring is mainly used to prevent liquid from leaking around the pipe and leaking from the connection port. The second sealing O-ring can strengthen the sealing of the inner drain pipe and further ensure the sealing of the inner drain pipe. At the same time, it also prevents problems with the first sealing ring. The second one can also play a backup strengthening role.

[0027] Preferably, the lining seal 2 is made of stainless steel or other materials that are not easily rusted.

[0028] Preferably, the lining seal 2 and the rainwater bucket body 1 are connected by welding or threading.

[0029] Preferably, an inclined surface is formed along the circumferential direction of the inner diameter edge of the lining seal 2 (as Figure 4 shown), so that the inner drain pipe 200 can be smoothly inserted.

[0030] The working principle of the present utility model:

[0031] First, machine-process the inner lining seal 2 so that the outer diameter of the inner lining seal 1 matches the circular opening of the rainwater hopper main body 1, and the inner diameter matches the outer diameter of the inner drain pipe 200. Secondly, machine-process the bevel cut of the inner diameter edge of the inner lining seal 2 so that the inner drain pipe 200 can be smoothly inserted. Then, machine-process two sealing grooves 41. The sealing ring 42 mainly prevents liquid from leaking around the pipe and leaking from the connection port. The second sealing O-ring can strengthen the sealing of the inner drain pipe and further ensure the sealing performance of the inner drain pipe. At the same time, it also prevents problems with the first sealing ring. The second one can also play a backup strengthening role. Finally, machine-process a threaded hole 5 at the top of the inner lining seal 2 close to the circular interface, and the threaded hole 5 is located behind the sealing structure 4. The inner lining seal 2 is fixedly connected to the wall inner drain pipe 200 by screwing a screw, preventing the large amount of water discharged from the water outlet from having an impact and causing the rainwater hopper to separate from the inner drain pipe.

[0032] At the same time, a filter screen 3 is provided at the place where the rainwater hopper main body 1 is close to the water inlet, which can prevent leaves and other garbage from entering the rainwater hopper and causing pipe blockage.

[0033] The utility model solves the problem of water leakage of the conventional elbow by using a rainwater hopper with good sealing performance; and solves the problem that the rainwater hopper is easily separated due to the rapid impact of water discharge. The utility model can receive a large amount of flushing water, and at the same time, a filter screen is added at the top, which is not easy to be blocked. And the side drainage omits the connecting elbow fittings and directly connects to the rainwater hopper, with a beautiful appearance.

[0034] Although the specific implementation manners of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should be covered by the scope protected by the claims of the present utility model.
