Description

Foam generating device and closestool

Technical Field

The utility model relates to the technical field of sanitary wares, in particular to a foam generating device and a closestool.

Background

When the toilet is used, a lot of people can encounter the situation that the buttocks are splashed with water, so that the buttocks are unsanitary. Because bacteria, viruses and the like can be remained in the toilet bowl if the toilet bowl is not cleaned in time under the condition of using a public toilet, the excrement mouth spreading of some infectious diseases is caused.

In order to solve the problem of water splashing in the toilet, a lot of people take measures to put toilet paper into the toilet so that the paper covers the water surface of the toilet. However, this method has a problem that the paper swells by absorbing moisture and does not break, and the toilet bowl is easily clogged.

In order to solve the problem of blockage caused by water splashing prevention, a closestool bubble spraying agent is generated, and when the closestool is used, the closestool is manually sprayed to the water surface of the closestool, and bubbles are formed on the water surface. However, this method requires a manual operation each time, and is short in use time and high in cost.
