[0030] How this atomizing device works: as shown in FIG. 1-FIG. 4, when the lever is pushed to fill liquid, the valve needle opens; when the lever is released, the lever is reset, the liquid in the piston cavity reaches a given volume, the liquid in the piston cavity instantly holds against the valve needle (when the liquid in the piston cavity reaches a given volume, push the lever, the pressure in the piston cavity gradually decreases, the liquid naturally holds against the valve needle, so that the valve needle can effectively seal the elastic body and prevent liquid from backflowing in the direction to the container); press the lever again, the elastic body is deformed. As the valve needle is seal-fit, the liquid will flows to the top of the elastic body which is forced to be deformed under a certain internal pressure (the elastic body is deformed under pressure, the elastic body sealing force slides to the opening underneath the thru-hole of the body, the liquid is naturally pressurized to eject); release the lever again, the elastic body naturally resets and seal-fit with the body under the action of resilience. More details are described as follows: push the lever to drive the piston, the liquid drives the valve needle when filling liquid, the area where the valve needle is seal-fit to the elastic body opens, the liquid smoothly enters the piston cavity through the supply passage in the elastic body. When the liquid in the piston cavity reaches a given volume, push the lever again to drive the piston, then the piston moves in the piston cavity. As the internal pressure in the piston cavity gradually decreases, it attempts to push the liquid from the piston cavity to the elastic body. As the liquid flows, the liquid first holds against the valve needle, so that the valve needle is tightly sealed with the elastic body sealing surface under the action of liquid, and the liquid will not backflow to the container. After the valve needle is closed, the liquid is compressed in the lid cavity on top of the supply passage underneath the thru-hole of the elastic body, the elastic body will be further deformed. Because the elastic body continues to slide along the sealing surface to the opening of the body with the elastic body, the elastic body will open. When the elastic body opens, the liquid will be distributed to the water outlet of the body. When the lever is released, the elastic body will smoothly reset and naturally seal with the body; because the elastic body is made of soft, easily deformed and resilient material, and given that it naturally rebounds under pressure, the curved surface of the elastic body is designed with the shape that allows for easy rebounding. Because the elastic body is designed in the position closer to the drainage area of the piston cavity, the liquid can naturally explode when the lever is pushed to test spray the liquid, and the liquid ejection is more explosive, the structure is designed to the extent that it has more explosive power and the test spraying pressure is stable per cycle, there is no obvious water droplets in the course of test spraying and the atomizing effect is improved.
