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, a drain opening is provided at the bottom of the water basin of a kitchen sink, and a drainer is installed on the drain opening. The drainer is connected to a drain pipe, and the water in the water basin can be discharged into the sewer through the drain pipe. Generally, in order to avoid large particles entering the drain pipe and causing pipe blockage problems, accessories such as a filter basket and a sealing cover are installed on the drainer. For example, Chinese Patent Publication No. CN205636943U discloses a sink pop-up drainer, which includes a main body sealed in the sink, a drain basket and a pop-up valve installed in the main body; a drain opening is formed in the main body, and the drain opening is communicated with the drain pipe of the sink. The drain basket is connected to the drain opening through the pop-up valve; each time the drain basket is pressed, the pop-up valve switches between the open and closed states. When the pop-up valve is in the open state, the space in the drain opening and the drain basket is communicated. When the pop-up valve is in the closed state, the space in the drain opening and the drain basket is isolated. The structure of this patent can realize the water storage and drainage of the sink by simply pressing the drain basket, and the operation is simple. However, the disadvantage is that the support feet are provided at the edge of the top cover and directly act on the drain basket, so the support feet may be deformed due to long-term pressing force, affecting the sealing performance. For this reason, the technical personnel in this field have proposed a solution, canceling the support feet and directly placing the top cover above the drain basket, solving the problem of the support feet, but the disadvantage is that once the drain basket is taken out, the top cover will directly sink into the main body of the drainer at this time and is difficult to take out, and its structure needs to be further improved.
