When the handle 38 is released for the first time, the second elastic body 36 pushes the second piston 37 in a direction away from the container 2; the liquid inlet cavity 351 is expanded, so that the air pressure in the liquid inlet cavity 351 is suddenly reduced to form negative pressure, the first ball 33 and the second ball 34 both move towards the liquid inlet cavity 351, the first opening 311 is opened, and the second opening 391 is sealed; at this time, the air pressure in the container 2 is large, so that the liquid in the container 2 enters the liquid inlet chamber 351 through the first flow channel 31 and the first opening 311, i.e., absorbs liquid, as shown in fig. 7 and 9.

Pressing the handle 38 for the second time, the second piston 37 in the liquid inlet chamber 351 presses the second elastic body 36 towards the container 2 again; at this time, the liquid in the liquid inlet chamber 351 pushes the first ball 33 and the second ball 34 toward the container 2, so that the first opening 311 is sealed, the second opening 391 is opened, and the liquid in the liquid inlet chamber 351 enters the second flow channel 39 through the second opening 391, then enters the oil outlet flow channel, then enters the spray channel, and finally is discharged out of the spraying device, i.e. spray, as shown in fig. 4, 5 and 6.

This cycle is repeated so that liquid is continuously dispensed from the spray device by depressing the handle 38.

6. The spray assembly of claim 1, wherein a window is formed at one end of the receiving chamber, the first piston further comprises a sliding section and a piston body, and the sliding section is movably disposed through the window;

the piston head and the inclined shoulder section are located outside the accommodating cavity, the piston body is located in the accommodating cavity, the outer end of the sliding section is connected with the inclined shoulder section, the inner end of the sliding section is connected with the piston body, and the piston body is further provided with a sliding piece used for sliding along the inner wall of the accommodating cavity.

7. The spray assembly of claim 6, wherein a portion of the outer wall surface of said piston body forms said slide.

8. The spray assembly of claim 1, wherein said outlet flow path further comprises a fourth channel, a fifth channel and a sixth channel disposed on said nozzle holder, one end of said fourth channel is connected to one end of said fifth channel, and the other end of said fourth channel extends out of said nozzle holder;

the other end of the fifth passage communicates with one end of the sixth passage, and the other end of the sixth passage communicates with one side of the second passage and may be aligned with the shoulder section, thereby providing the first piston with a force opposite to the elastic force.

9. A spraying device is characterized by comprising a container for containing liquid and a spray head connected to one end of the container, wherein a liquid inlet component and the spraying component as claimed in any one of claims 1 to 8 are arranged in the spray head, and the liquid inlet component is communicated with a liquid outlet channel of the spraying component;

the liquid inlet assembly comprises a fastener buckled on an opening of the container and a main body arranged on the fastener, the main body and the fastener are enclosed to form a liquid inlet cavity, the liquid inlet cavity is communicated with the container through a first flow passage, and the liquid inlet cavity is communicated with the liquid outlet channel through a second flow passage; a first check valve is arranged in the first flow passage, and a second check valve is arranged in the second flow passage;

the first flow passage is provided with a first opening communicated with the container, the first one-way valve comprises a first ball body, and the first ball body is movably arranged at the first opening to block the container and the liquid inlet cavity by blocking the first opening;

the second flow channel is provided with a second opening communicated with the liquid inlet cavity, the second one-way valve comprises a second ball body, and the second ball body is movably arranged at the second opening to block the liquid inlet cavity and the liquid outlet channel by plugging the second opening;

the first sphere and the second sphere are the same size.

10. The spraying device according to claim 9, wherein the inner diameter of the first opening gradually decreases from an end close to the liquid inlet chamber to an end far from the liquid inlet chamber, and the first ball is movably disposed at the first opening and blocks the first opening under its own weight;

the inner diameter of the second opening gradually shrinks from one end far away from the liquid inlet cavity to the other end close to the liquid inlet cavity, the second ball body is movably arranged at the second opening, and the second opening is blocked under the negative pressure action of the liquid inlet cavity.
