bottle cap and a limiting and positioning component, the humidification bottle mouth is arranged in the middle of the upper end of the humidification bottle body, the
bottle cap is arranged outside the humidification bottle mouth, and the limiting and positioning component comprises a clamping boss rib arranged on the lower side of the inner wall of the
bottle cap. According to the L-shaped structure for limiting and positioning the bottle opening of the humidification bottle, the
bottle cap is clamped at the bottle opening through the clamping boss rib connected with the limiting check block rib and the positioning groove rib in the clamping mode, so that the bottle cap and the bottle body are connected, the clamping boss rib is limited by the limiting check block rib of the bottle opening and positioned by the positioning groove rib of the bottle opening, and when the bottle cap and the bottle opening are assembled, the bottle cap and the bottle opening can be clamped and positioned through the clamping boss rib. The bottle cap is limited and positioned, excessive
assembly is avoided, the stress fatigue of the bottle cap is reduced, the application range of all bottle body and bottle cap
assembly structures is wide, and the bottle cap can be used for a long time.
