Abstract

The invention provides a pressing opening-closing floor drain which can be opened when required, and is closed at ordinary times to prevent off-flavor gas in a downstair pipeline from channeling intoa room along the floor drain. The pressing opening-closing floor drain comprises a water inlet bowl, a filter screen plate, a partition plate and a pipe, wherein the filter screen plate is fixedly connected with the top end of the water inlet bowl. The pressing opening-closing floor drain is characterized in that the pipe penetrates the water inlet bowl upwards and is fixedly connected with the water inlet bowl, the top end of the pipe is closed, the pipe is provided with a water outlet communicated with the water inlet bowl and the inside of the pipe, the upper portion of the water inlet bowlis provided with a straight tubular structure, the bottom end of the straight tubular structure is lower than the top end of the water outlet, the filter screen plate is provided with a through hole,the partition plate slidably sleeves the pipe through a limit through hole in the middle of the partition plate and is provided with a pressing column penetrating the through hole upwards, the top end of the pressing column penetrates the filter screen plate and is exposed to the filter screen plate, a spring is arranged between the partition plate and the filter screen plate, and the partition plate moves upwards and approaches to the filter screen plate by the aid of elastic force of the spring.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a push-to-open and close floor drain. Background technique [0002] Floor drains are installed in bathrooms, kitchens, and balconies to facilitate drainage. Floor drains are equipped with partitions to prevent debris from flowing into the pipes with water and blocking the pipes. In actual use, the frequency of use of some floor drains is very low, but the odor gas in the pipeline downstairs will enter the room along the floor drain, affecting the air quality. In order to solve the above problems, some floor drains are provided with U-shaped pipes, and the water in the U-shaped pipes is used to seal the floor drains, thereby preventing odorous gases from escaping. However, if the frequency of use is low, the water in the U-shaped pipe will also evaporate, losing the function of sealing the floor drain. Contents of the invention [0003] The purpose of the present i...
