Sprayer capable of preventing mistaken pressing

Abstract

The invention discloses a sprayer capable of preventing mistaken pressing, comprising a sealed cup, wherein the sealed cup comprises a cup body; an outwards convex connecting part is arranged on the upper end face of the cup body; a mounting hole is formed in the middle of the outwards convex connecting part; a pump chamber is arranged inside the outwards convex connecting part; an inner gasket is arranged between the top end of the pump chamber and the outwards convex connecting part; a limit convex ring is arranged on the outer wall of the upper end of the pump chamber; the sealed cup is provided with a plurality of inwards convex grabbing openings which enable the pump chamber to be tightly connected to the sealed cup; the inwards convex grabbing openings are arranged on the lower end face of the limit convex ring in a clamping way; a pump rod assembly is arranged inside the pump chamber; a button assembly capable of driving the pump rod assembly to work is arranged on the upper end of the pump rod assembly; a protecting cover capable of preventing the button assembly from moving downwards under the effect of force is arranged between the button assembly and the cup body; the protecting cover is sleeved outside the outwards convex connecting part. The invention aims at providing the sprayer capable of preventing mistaken pressing, which is simple in structure, convenient in connection, capable of effectively preventing the mistaken pressing, rapid in starting up a pump, and relatively stable in extrusive quantity.

Description

technical field [0001] The invention relates to an anti-mispress sprayer. Background technique [0002] Because of its exquisite design and convenient use, the sprayer has been widely used in daily chemical and pharmaceutical industries. However, the existing sprayer has complex structure, great manufacturing difficulty, high production cost and inconvenient assembly. [0003] Existing sprayers generally do not have protective devices, and the button of the sprayer is easily squeezed and moved down due to misoperation during transportation or use, resulting in waste or unnecessary accidents. [0004] In addition, due to the defects in the design of the existing sprayer, there are disadvantages such as relatively slow start of the pump during use, relatively unstable spraying volume, and the like. Can not meet the needs of users. [0005] Therefore, the existing sprayer needs to be further improved. Contents of the invention [0006] The object of the present invention ...
