Portable sprayer

The present invention provides a portable sprayer, in particular a portable sprayer that reduces liquid residue, and which can be attached directly to the mouth tube or mask, because of its light weight, it is particularly suitable for use in action.

There is a growing variety of health care methods in the market. One way is to put the syrup or maintenance solution (described later with the syrup) into the atomizer. The operation of the atomizer can make the syrup form a mist, which allows The user can easily inhale by mouth or nose.

When the user uses the atomizer, the medicine is first placed in the container of the atomizer, and the oscillating piece is driven to vibrate at a high frequency through the circuit in the atomizer, and the surface of the liquid is raised by the contact of the oscillating piece with the syrup. Cavitation occurs around the raised liquid surface, causing the liquid to atomize into a small molecule aerosol.

However, there is a problem with the atomizer in the workshop: when the syrup is often used at the end, there is still some syrup left in the container, that is, when the bottling is used, the syrup in the container cannot be used completely, and it is easy to cause bacteria to germinate, or There are many problems with the conflict with the potion used next time. In view of this, it is necessary to propose a solution.
