Detailed Description

It is to be understood that the terms "upper," "lower," "horizontal," "top," "bottom," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must be in a particular orientation, constructed and operative in a particular orientation, and are not to be construed as limiting the present invention.

Example 1

The spraying device comprises a water tank 1 and a pressing pump 2, wherein the water tank 1 is used for supplying water to the pressing pump 2;

the pressing pump 2 comprises an upper cover 21, a piston 3 and a shell 22; a water inlet cavity 4 and a water outlet cavity 5 are sequentially arranged in the shell 22 from top to bottom, the water inlet cavity 4 is provided with a water inlet 41, an opening of the water inlet 41 is downward, a water inlet valve core 42 is arranged in the water inlet 41, and the water inlet valve core 42 falls down under the action of gravity to block the water inlet 41; the water outlet cavity 5 is provided with a nozzle 51 and a water outlet valve core 52, the nozzle 51 is arranged at the bottom of the water outlet cavity 5, and the water outlet valve core 52 is movably arranged in the water outlet cavity 5 and is propped against the communication position of the water inlet cavity 4 and the water outlet cavity 5 from bottom to top; the piston 3 is arranged in the water inlet cavity 4 and used for changing the size of the cavity of the water inlet cavity 4.

In this embodiment, the pressing pump 2 and the water tank 1 are both cylindrical, and the pressing pump 2 is installed in the water tank 1 and has the same center. The water inlet 41 is communicated with the water tank 1, the nozzle 51 is exposed on the lower surface of the water tank 1, the water tank 1 comprises a tank body 12 and a tank cover 11, a button 13 is arranged on the tank cover 11, and the bottom of the button 13 is connected with the top of the piston 3; the button 13 and the upper cover 21 are flush with the upper surface of the water tank 1, and a sealing ring 14 is arranged among the button 13, the upper cover and the water tank.

Be equipped with reset spring 31 in piston 3 and the intake antrum 4, guarantee to push down button 13 artificially and promote piston 3 and realize the water spray after, piston 3 can upwards reset under reset spring 31's effect.

The water inlet valve core 42 is a sphere, and the water inlet 41 has a circular truncated cone structure with a large upper part and a small lower part; when the spraying device is horizontally placed, the water inlet valve core 42 blocks the water inlet 41 under the action of gravity, and the water inlet is closed.

The water outlet valve core 52 is connected in the water outlet cavity 5 through an elastic member 53, the water outlet valve core 52 has a structure with a gradually increasing cross-sectional area from top to bottom, and when the water outlet valve core 52 is not stressed, the elastic member 53 jacks up the water outlet valve core 52 to seal an inlet of the water outlet cavity 5.

When the spraying device of the present embodiment is placed horizontally, the mouth of the nozzle 51 faces downward; due to the gravity, the water inlet valve core 42 is closed, the button 13 is pressed, the piston 3 of the pump 2 is pressed, high pressure is formed in the water inlet cavity 4, the liquid pressure extrudes the water outlet valve core 52, the elastic piece 53 contracts, the water outlet valve core 52 is opened, and the liquid flows into the water outlet cavity 5 and reaches the nozzle 51 to produce spray. After spraying, the liquid pressure in the water inlet cavity 4 is released, the elastic element 53 is reset, the water outlet valve core 52 closes the inlet of the water outlet cavity 5, the piston 3 of the pressing pump 2 is also reset under the action of the reset spring 31, at the moment, negative pressure is formed inside the water inlet cavity 4, and pressure difference is generated between the negative pressure and the water tank 1, so that the liquid in the water tank 1 jacks up the water inlet valve core 42 to be supplemented into the water inlet cavity 4.
