Specifically, in the second embodiment and the fourth embodiment, the third housing 30 may not be provided with the spout cover 52, and the spout end 41 thereof may be folded to form a cover body instead of being provided with a large opening, and then the cover body may be provided with the corresponding third through hole 31, and the water mist sprayed from the atomizer 71 passes through the second through hole 21, then continues to pass through the third through hole 31, and is then sprayed into the external oral cavity. The third through hole 31 is preferably arranged coaxially with the second through hole 21, and a nozzle slider 54 may be further provided to shield the third through hole 31, thereby keeping the third through hole 31 clean.

In use, the cap 68 of the liquid storage bottle 61 is removed first, then the tail cap assembly 55 is pulled out to expose the opening 43, the liquid storage bottle 61 is inserted into the inner cavity of the first housing 10, and the first projection 12 of the first housing 10 and the first groove 67 of the liquid storage bottle 61 form a snap connection, so that the liquid storage bottle 61 is fixed in the inner cavity of the first housing 10. At the same time, the flow guiding column 63 is abutted against the atomizer 71, so that the atomizer 71 can atomize the liquid on the flow guiding column 63.

Then the spout cover 52 is pulled out, or the spout slider 54 is pushed open, and then the control button 83 is pressed, so that the control chip 82 drives the atomizer 71 to perform atomization treatment, water mist is formed to be sprayed out of the atomizer 71, and then the water mist passes through the second through hole 21 and is sprayed into the external oral cavity, or passes through the second through hole 21 and the third through hole 31 and is sprayed into the external oral cavity, so that the oral cavity is cleaned or treated.

After use, the spout cover 52 may be replaced or the spout slider 54 pushed back to protect the spout end 41 from being cleaned. When the use of the liquid in the liquid storage bottle 61 is completed, the tail cap assembly 55 can be opened again for quick replacement, so that bacteria breeding in the liquid storage bottle 61 is avoided.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
