[0043] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] like Figure 3 and Figure 4 As shown, the side wall of the medicine cup 3 is provided with a positioning groove 31, and the ultrasonic atomizer sheet 5 is arranged in the positioning groove 31. Placing the ultrasonic atomizer sheet 5 in the positioning groove 31 can improve the assembly structure stability of the ultrasonic atomizer sheet 5 and avoid the ultrasonic atomizer sheet 5 from being displaced during use and affecting the atomization effect.

[0049] A liquid outlet 32 ​​is provided between the positioning groove 31 and the liquid storage chamber 30, and the liquid outlet 32 ​​is used to guide the liquid medicine in the liquid storage chamber 30 to the ultrasonic atomization sheet 5;

[0050] The ultrasonic atomizer sheet 5 is used to ultrasonically atomize the medicine to form liquid mist. Specifically, when an external voltage is applied to the ultrasonic atomizer sheet 5, the ultrasonic atomizer sheet 5 will generate high-frequency mechanical vibrations. When the medicine flows to the surface of the ultrasonic atomizer sheet 5, the high-frequency mechanical fluctuations will cause the medicine to form a fine liquid layer.
