Embodiment Construction

[0022] In conjunction with the accompanying drawings, the implementation mode takes the working principle of the present invention as an example. When the wrench 18 is pulled, the wrench presses down on the main body 3, which drives the pump body and the internal operating mechanism to move downward. First, the main body 3, the valve stem 5, and the valve needle 11 move downward. At the same time, due to the friction between the pump body 14 and the piston 10, the seal between the valve needle 11 and the piston 10 is opened (see Figure 1.1). When the A side of the valve stem 5 moves down to the B side of the piston 10, the piston 10 Also follow the start downward movement. The liquid inside the pump body 14 flows into the inner hole of the valve stem 5 through the three grooves on the valve needle 11, and then is sprayed out through the small-hole spray sheet 1, because under the action of the small-hole spray sheet 1, the liquid is in the form of mist. While the piston 10 mo...

Abstract

The present invention relates to miniature sprayer, and is one hand beating miniature sprayer. The key points of the present invention includes one ventilating hole in the middle part of the pump body and the piston; communicated central holes in spraying sheet, head cap and main body; communicated central holes in main body, switch and valve rod; connection between the lower section of the connecting seat and the upper section of the pump body; large ring between the connecting seat and the pump body; the switch with connected boss, extending block and limit stage; the connecting seat with inner boss, inner rib, limit stage, clamping notch and supporting shaft; and the inner boss to support the pump body and limit inner plug. The present invention has raised sealing property, less residual liquid after spraying and perfect inner structure design.

Description

technical field [0001] The invention relates to the field of micro-sprayers, in particular to a hand button type micro-sprayer. Background technique [0002] At present, there are two types of micro-sprayers: press type and hand button type. The pump body of the press type sprayer adopts a double spring structure, which has the advantages of good sealing performance, strong spraying power and fine droplets, but compared with the hand button type sprayer, the spray volume is higher Small, if the spray volume is increased, since it is a vertical downward pressure spray, a relatively large downward force needs to be added, so the hand feel is heavy. In contrast, the known hand-button sprayer has a larger discharge volume, and the trigger is used to pull the spray, so the hand feel is not too heavy, but since the straw moves up and down during spraying, there is more residual liquid in the bottle. In addition, the internal sealing is not good, and the wrench is pulled when it i...
