Description

The present invention relates to a nozzle cleaning aerosol products of bidet.

There is known a warm water flush toilet seat that ejects warm water from a nozzle provided in a toilet seat to wash the anus. Such warm water flush toilet seats were initially introduced in hospitals and welfare facilities, then installed in hotels, offices, and the like, and in recent years have become widespread in ordinary households.
The nozzle in this warm water flush toilet seat squeezes down below the anus when in use and spouts warm water upward, so it is easily soiled with scales and dirt. Therefore, in order to keep the nozzle clean, the toilet seat for washing with hot water is equipped with an automatic cleaning device for the nozzle, and the nozzle is washed before and after use, but it is difficult to wash sufficiently, and it becomes dirty due to long-term use. There were problems such as sticking out and causing mold generation due to dirt.
In order to solve such a problem, a cleaner (for example, refer to Patent Document 1) having a brush for cleaning the nozzle, an aerosol cleaning agent for injecting a cleaning material or the like toward the nozzle (for example, refer to Patent Document 2). Etc.) have been proposed.
