Description

  The present invention relates to a local cleaning apparatus that cleans a human body part, and more particularly to a local cleaning apparatus that sprays cleaning water containing microbubbles on a human body part and cleans it.

  In recent years, a cleaning apparatus for cleaning a human body part with cleaning water has become widespread, but mere cleaning water has a strong impact force on the local part and does not provide sufficient comfort during cleaning.

  In order to improve the detergency of water-saving and spouted washing water or give a soft feeling of washing, air is mixed into the washing water, and a local washing device using this air as bubbles has been proposed. (Patent Document 1).

However, what is described in Patent Document 1 is a local cleaning device that refines an air mass in order to obtain a state where water and air are completely independent through air dispersion. In this device, the degree of refinement is as follows. The bubble diameter is about 1 mm, and it is not possible to expect a sufficient cleaning effect using such a large bubble, and it is difficult to sufficiently promote local blood circulation. There is a problem that considerable energy is required to make the bubbles fine before the bubble diameter is 100 μm or less, and it is difficult to realize microbubbles.
