[0021] Embodiment: Please refer to Figure 1 A hand-held sprayer shown in the figure, including a gun body 5, a piston 9 and a connecting cover 10. The top of the inner cavity of the connecting cover 10 is fixedly installed with the gun body 5, and the bottom of the inner cavity of the connecting cover 10 is slidably installed with the piston 9;

[0022] The top of the inner cavity of the gun body 5 is fixedly installed with a plastic spring 7. The bottom of the inner cavity of the piston 9 is clamped with a plastic ball 8, and the bottom of the piston 9 is fixedly installed with a plastic straw 13;

[0023] Among them, the plastic straw 13 draws the liquid from the container to the hand-held sprayer.

[0024] In this embodiment, referring to Figure 1 the figure shown, the plastic spring 7 and the plastic ball 8 are in contact with each other, and the bottom of the plastic spring 7 is in contact with the bottom of the inner cavity of the piston 9;

[0025] Among them, when in use, the liquid is lifted by the pressure of the plastic spring 7 and finally sprayed out;

[0026] The plastic ball 8 seals the piston 9 so that the piston 9 does not leak air;

[0027] The piston 9 causes suction and compression.

[0028] In this embodiment, referring to Figure 1 the figure shown, an outer cover 1 is provided on the outer wall of the gun body 5;

[0029] Among them, the outer cover 1 improves the aesthetics of the entire hand-held sprayer, and all small components are hidden inside the outer cover.
