In order to understand the technical features and practical functions of the present invention in detail, and in accordance with the contents of the specification, the following is further illustrated in the following preferred embodiments.

Referring to Figures 1 to 4, the nebulizer for safe use of the present invention is provided with a storage bottle 10, an outer cover 20, a safety switch 30 and a pressing member 40, wherein:

The storage bottle 10 is a hollow can body for storing a liquid. The upper opening of the storage bottle 10 is provided with a sealing cover 13 so that the upper opening of the storage bottle 10 is sealed. The cover 13 is provided at the center with an air outlet 11 , and the storage bottle 10 is provided with a jet tube 12 at the air outlet 11 , the top end of the air tube 12 is perpendicular to the air outlet 11 , and further, the air tube 12 is in the middle portion. The outer surface is provided with a flat plate 14.

The outer cover 20 is disposed above the air outlet 11 against the outer diameter of the sealing cover 13 of the storage bottle 10. The outer cover 20 is provided with a line opposite to the air outlet 11 at the top surface. The upper cover 21 has a side opening 22 communicating with the upper opening 21 on the outer surface of the outer cover 20. The outer cover 20 has an annular limiting ring 23 laterally protruding from the outer surface of the bottom. The cover 20 is further provided with a plurality of limiting blocks 24 at an outer surface of the upper end of the limiting ring 23, so that the outer cover 20 forms an annular sleeve between the limiting ring 23 and the plurality of limiting blocks 24. With the slot 27, as shown in FIG. 3 and FIG. 4, the outer cover 20 is further provided with a sliding slot 25 at the top surface of the limiting ring 23 opposite to the side opening 22, and the sliding slot 25 is adjacent to the slot 25 Abutting protrusions 26 are respectively protruded outwardly at the two ends. Preferably, as shown in FIG. 6, a sliding surface 261 is formed between the inner side surfaces of the two abutting protrusions 26, and the two abutting protrusions are provided. The outer side surfaces of the 26 phase away from each other are respectively a limiting surface 262, wherein the angle of each limiting surface 262 is larger than the angle between the sliding surfaces 261.

The safety switch 30 is rotatably sleeved on the outer cover 20 and is provided with a rotating ring 31 and an ejector piece 32. The rotating ring 31 is rotatably disposed in the sleeve 27 of the outer cover 20 and is received by the outer cover 20 The limitation of the limiting ring 23 and the plurality of limiting blocks 24 is such that the rotating ring 31 is not separated from the outer cover 20. Referring to FIGS. 3 and 4, the rotating ring 31 is convex downwardly on the bottom surface. a guiding block 33 extending into the sliding slot 25 and optionally straddles one of the abutting projections 26 to rotate the rotating ring 31 relative to the outer cover 20 33 can slide in the chute 25 as shown in FIG. 6 and straddle one of the abutting lugs 26 and abut against it, thereby limiting the angle of rotation of the rotating ring 31 relative to the outer cover 20.

The ejector piece 32 is convexly formed on the top surface of the rotating ring 31 adjacent to the guiding block 33 and facing the side opening 22 of the outer cover 20. Please see the ejector piece 32 as shown in FIGS. 5 and 7. Preferably, the safety switch 30 is provided with a plurality of spaced apart ribs 35 on the outer surface of the rotating ring 31 and the ejector piece 32. The plurality of ribs 35 increase the friction of the user to push the safety switch 30, so that the safety switch 30 can be easily rotated relative to the outer cover 20.

The pressing member 40 is pivotally coupled to the inner portion of the outer cover 20 and selectively abuts against the safety switch 30. The pressing member 40 is provided with a pivoting post 44, a button string hole 42 and a pressing end. 43. The pivoting end 41 of each of the two ends of the pivoting column 44 of the pressing member 40 is pivotally coupled to the inner portion of the outer cover 20 as shown in FIGS. 5 and 8. The key string 42 is stringed. The abutting plate 46 is formed on the bottom surface of the pressing member 40 and is formed in a triangular shape and abuts against the flat plate 14 of the air tube 12, and the pressing end 43 extends through the side opening 22 The outer cover 20 can abut against the ejector piece 32. Preferably, the pressing member 40 is provided on the back surface of the pressing end 43 with a positioning portion 45 that can abut against the locking protrusion 34, so that the pressing portion The member 40 can be stably abutted against the ejector piece 32 of the safety switch 30, so as to avoid a user's accidental contact and a liquid state such as a mist, a water column or a bubble.

The sprayer of the present invention is used as shown in FIGS. 9 and 10. First, the user can push the rotating ring 31 between the limiting ring 23 and each limiting block 24 through the ribs 35, opposite to the outer cover 20. The sleeve groove 27 is rotated to separate the pressing piece 32 from the pressing end 43 of the pressing member 40 as the rotating ring 31 rotates, and moves in a direction away from the opening 22 of the outer cover 20 side. Even if the positioning portion 45 of the pressing member 40 is separated from the positioning bump 34 of the safety switch 30, when the rotating ring 31 is rotated relative to the outer cover 20, the guiding block 33 is along the line as shown in FIG. The sliding slot 25 moves away from one of the abutting projections 26 and moves toward the other abutting projection 26 , wherein the limiting surface 262 of each of the abutting projections 26 can limit the guiding block 33 . Further, the position of the pushing piece 32 is positioned, that is, the safety switch 30 is placed in a set or released state. Further, the sliding surface 261 between the two abutting protrusions 26 can make the guiding block 33 smooth. The ground moves in the chute 25.

Referring to FIG. 11 , when the pushing piece 32 is separated from the pressing end 43 of the pressing member 40 , the user can press the pressing end 43 to press the pressing member 40 against the plate 46 . The flat plate 14 of the middle portion of the squib 12 is pushed downward to discharge the liquid stored in the storage bottle 10 through the blast tube 12, thereby completing the use of the sprayer of the present invention, and the user uses the sprayer. Thereafter, the rotating ring 31 can be reversely pushed to rotate relative to the outer cover 20 according to the foregoing operation manner, so that the guiding block 33 moves along the sliding slot 25 to the initial position and abuts against one of the abutting protrusions 26, At the same time, the pushing piece 32 is moved to the lower side of the pressing end 43, and the engaging protrusion 34 is abutted against the positioning portion 45, so that the pressing end 43 can be prevented from being sprayed by the improper external force, and the water column is sprayed. A liquid state such as a bubble or a bubble.

According to the above technical features, the sprayer that can be safely used in the present invention can restrict the movement of the pusher 40 by the rotation of the safety switch 30 relative to the outer cover 20 during use, thereby effectively avoiding user error. Touching the pressing member 40, pushing the nozzle tube 12 to cause a liquid state such as a mist, a water column or a bubble to be ejected, and further providing two abutting protrusions 26 in the sliding groove 25, and The guiding block 33 is disposed at the bottom of the rotating ring 31, and the guiding block 33 and the two abutting protrusions 26 abut against each other, thereby providing a user to confirm that the safety switch 30 is in a set or released state, and the cover is The limiting ring 23 and the plurality of limiting blocks 24 are disposed on the 20 to form the sleeve groove 27, so that the rotating ring 31 of the safety switch 30 can be stably rotated relative to the outer cover 20 without falling off. Since the rotating ring 31 and the ejector piece 32 are provided with a plurality of ribs 35, the user can conveniently and labor-savingly rotate the safety switch 30, which is quite convenient to use and greatly enhances the safety of use, thereby providing a Sprayer for safe use.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
