Description

Novel bouncing drainer

Technical Field

The utility model relates to the technical field of kitchens and bathrooms, in particular to a novel bouncing drainer.

Background

In order to facilitate water storage and drainage in a bathtub, a hand sink or a vegetable basin, a drainer is generally arranged at the bottom end of the bathtub, the hand sink or the vegetable basin, and the water storage and drainage of the bathtub, the hand sink or the vegetable basin is realized by controlling the switch of the drainer, and the drainer generally comprises a turnover drainer and a bouncing drainer. The bouncing drainer generally comprises a bouncing switch and a fixed seat fixed with the bouncing switch; when the bouncing switch is pressed, the bouncing switch bounces, the waterway is conducted, drainage is carried out, the bouncing switch is pressed again, the bouncing switch is reset, and the water sealing plate is sealed with the waterway of the sewer pipe to store water.

CN217759116U (publication day 2022, 11, 8) discloses an improved bouncing drainer, which is arranged on a filter screen above a water sealing plate in a detachable manner, and when in use, the driving rod drives the water sealing plate to press down by pressing the driving rod, so that the bouncing switch is switched between two positions, namely, the water sealing plate is in a conducting state and a sealing state. Because the driving rod filter screen is in sliding connection, when the water sealing plate state is changed, the position of the filter screen does not need to be changed, and the filtering function is not affected. When the filter screen needs to be cleaned, the driving rod is detached from the water sealing plate, and the driving rod and the filter screen are independently detached for cleaning, so that the driving rod and the filter screen do not need to be detached together.

However, when the water sealing plate is closed (in a water-closing state), the product only realizes sealing at the water sealing plate, is single-stage sealing, and if the sealing plate is damaged, the water-closing effect is completely lost. The present inventors have further improved upon the product of CN217759116U to solve the above problems.

In view of the above, the present inventors have made intensive studies to solve the above-mentioned drawbacks of the prior art.
