[0041] Furthermore, a limiting groove 13 is provided on the inner wall of the outer sleeve 12, and the bottom end of the outer wall of the push cover 3 is integrally connected to a limiting slider 37, and the limiting slider 37 is clamped in the limiting groove 13 to ensure that the push cover 3 can only move up and down in the outer sleeve 12, that is, to ensure that the push cover 3 cannot rotate relative to the rhinitis medicine bottle 1, thereby ensuring that the baffle 6 is always directly above the baffle 7.

[0042] Furthermore, the lower end of the pressing pump 2 is connected to a liquid inlet pipe 21, and the upper end of the pressing pump 2 is connected to a liquid outlet pipe 22. The bottom end of the liquid inlet pipe 21 is located at the bottom of the bottle of the rhinitis medicine bottle 1. The pressing cover 3 is fixedly connected with a docking block 31, and one side of the docking block 31 is connected to a liquid guide tube 32. The body of the liquid guide tube 32 passes through the side wall of one side of the pressing cover 3. A medicine flow channel 33 is opened in the docking block 31, and a liquid outlet slot 34 is opened at the bottom of the docking block 31. The liquid guide tube 32 is connected to the bottom of the rhinitis medicine bottle 1. 32, the medicine flow channel 33 is connected to the liquid outlet slot 34, and the upper end of the liquid outlet tube 22 is inserted in the liquid outlet slot 34, and the liquid guide tube 4 is inserted at one end of the liquid guide tube 32 located on the outside of the pressing cover 3, so that the pressing pump 2 can extract the rhinitis medicine solution from the bottom of the bottle of the rhinitis medicine bottle 1 through the liquid inlet tube 21, and transport the medicine solution to the liquid guide tube 4 through the liquid outlet tube 22, the medicine flow channel 33 and the liquid guide tube 32 in turn, so as to realize the extraction and flow of the rhinitis medicine solution.

When the liquid guiding tube 4 is inserted in the liquid guiding tube 32, the sealing rubber rings 41 and the annular sealing grooves 35 are locked and sealed to ensure that the liquid guiding tube 4 can rotate relative to the liquid guiding tube 32, and the delivered rhinitis medicine solution will not overflow from the gap between the liquid guiding tube 4 and the liquid guiding tube 32;

[0044] Furthermore, a positioning protrusion 36 is integrally connected to the inner wall of one end of the liquid guiding tube 32 located on the outer side of the pressing cover 3, and the connection position of the positioning protrusion 36 is located between the two groups of annular sealing grooves 35. The liquid guiding tube 4 is inserted into the tube body of the liquid guiding tube 32 and is also provided with a positioning groove 42, and the opening position of the positioning groove 42 is located between the two groups of sealing rubber rings 41. The positioning protrusion 36 and the positioning groove 42 are both distributed in a cross shape, and the positioning protrusion 36 and the positioning groove 42 are connected in a one-to-one corresponding manner, so that when the liquid guiding tube 4 is rotated relative to the liquid guiding tube 32, each rotation amplitude of 90° can make the positioning groove 42 re-connected with the positioning protrusion 36, that is, the liquid guiding tube 4 can be positioned and rotated to drive the atomizing spray assembly 5 to be parallel or perpendicular to the nasal medicine bottle 1, that is, the sprayer can be easily switched to a non-sprayable state or a sprayable state.

[0045] like Figure 1 , Figures 6 to 10As shown, the body of the spray pipe 51 of the atomizing spray assembly 5 is provided with a plurality of annular limiting grooves 55, and the annular limiting grooves 55 are provided at one end of the spray pipe 51 close to the spray head 52.
