DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1-3As shown, a filter comprises a mounting seat 1 and a funnel 2 located in the mounting seat 1. The mounting seat 1 is used to be mounted on a drainage hole reserved on the ground. Water in the room flows into the funnel 2 for drainage, which is used to prevent excessive debris from entering the drainage hole and causing blockage. The mounting seat 1 is provided with a mounting hole 3 that penetrates the mounting seat 1. The funnel 2 is installed in the mounting hole 3. The side wall of the mounting hole 3 is provided with a limiting step 4, and the funnel 2 is placed on the upper end of the limiting step 4. The funnel 2 is detachably installed in the mounting hole 3. The funnel 2 includes a disposable filter net that can be removed and replaced. A connecting ring 5 is provided at the upper end of the funnel 2. The funnel 2 is placed on the upper end of the limiting step 4 through the connecting ring 5. There is no connection between the connecting ring 5 and the mounting hole 3. The funnel 2 is directly placed on the upper end of the limiting step 4 through the connecting ring 5. The limiting step 4 supports the connecting ring 5 from below, and the funnel 2 cannot fall, which is convenient for users to easily take out the funnel 2 for replacement, and avoid excessive dirt accumulation and odor. The port of the funnel 2 is detachably installed in the connecting ring 5 . If the funnel 2 is too dirty and unsuitable for continued use, it can be removed and replaced with a new funnel 2 installed on the connecting ring 5 .

[0024] The funnel 2 also includes a plastic funnel or a metal funnel. If the funnel 2 is too dirty, it can be disassembled, cleaned, and then reinstalled for use.

[0025] The connecting ring 5 includes an upper connecting ring 6 and a lower connecting ring 7, which are connected by threads, and are convenient to install or disassemble. An inner side of the lower end of the upper connecting ring 6 is provided with an inwardly concave upper connecting portion 8, and an outer side of the upper end of the lower connecting ring 7 is provided with a lower connecting portion 9 adapted to the upper connecting portion 8, and an external thread is provided on the side wall of the upper connecting portion 8, and an internal thread is provided on the side wall of the lower connecting portion 9. When the upper connecting ring 6 is connected to the lower connecting ring 7, the lower connecting ring 7 is embedded in the upper connecting portion 8, and the upper connecting ring 6 is embedded in the lower connecting portion 9, and the internal thread and the external thread are matched and connected with each other.

[0026] The inner wall of the upper connecting ring 6 is provided with a blocking piece 10 extending inwardly, and the blocking piece 10 abuts against the top of the lower connecting ring 7 to prevent the threaded connection from being screwed in too deeply.

[0027] The end of the funnel 2 is provided with a connecting piece 11 extending outward, and the funnel 2 is detachably mounted on the connecting ring 5 by clamping the connecting piece 11 between the blocking piece 10 and the lower connecting ring 7. The tighter the upper connecting ring 6 and the lower connecting ring 7 are threadedly connected, the tighter the connecting piece 11 is clamped, and it is not easy to fall off.

[0028] The inner diameter of the mounting hole 3 is equal to the outer diameter of the connecting ring 5, and the outer contour of the connecting ring 5 matches the inner contour of the mounting hole 3. The connecting ring 5 is placed into the mounting hole 3 with the funnel 2, and the gap between the connecting ring 5 and the mounting hole 3 is small to prevent debris from falling in.

[0029] A pull ring 12 is provided at the upper end of the connecting ring 5. Both sides of the pull ring 12 are rotatably connected to the inner wall of the connecting ring 5, and the pull ring 12 is pivotally connected to the inner wall of the upper connecting ring 6, facilitating the user to lift the pull ring 12 to take out the funnel 2. After the funnel 2 is installed, the pull ring 12 is rotated to make it fit against the upper end of the baffle 10.

[0030] A guiding surface 13 is provided inside the upper end of the connecting ring 5. The guiding surface 13 is an inclined plane, which can guide the water on the ground into the funnel 2, helping to drain water faster.

[0031] An outwardly extending fixing piece 14 is provided at the upper end of the mounting seat 1. The fixing piece 14 fits against the groove reserved on the ground for stabilizing the entire mounting seat 1.
