Description

Technical Field

[0001] The utility model relates to the technical field of drainers, and more specifically to a sink drainer. Background Art

[0002] At present, the bottom of the water basin of the kitchen sink is provided with a drain port, and a drainer is installed on the drain port, and the drainer is connected to the drain pipe, and the water in the water basin can be discharged into the sewer through the drain pipe. Generally, in order to avoid the problem of large particles entering the drain pipe and causing pipe blockage, accessories such as a filter basket and a sealing cover are installed on the drainer. For example, the Chinese patent announcement number is CN205636943U, which discloses a sink bouncing drainer, including a body sealed in the sink, a drain basket and a bouncing valve installed in the body; a drain port is opened in the body, the drain port is connected to the drain pipe of the sink, and the drain basket is connected to the drain port through a bouncing valve; each time the drain basket is pressed, the bouncing valve switches between the open and closed states, when the bouncing valve is in the open state, the drain port and the space in the drain basket are connected, and when the bouncing valve is in the closed state, the drain port and the space in the drain basket are isolated. This patented structure can store water and drain water from the sink by simply pressing the drain basket, and is easy to operate. However, the disadvantage is that the edge of the top cover is provided with supporting feet that directly act on the drain basket, so the supporting feet may be deformed due to long-term pressing force, affecting the sealing.
