Pump-dispensing atomizer
View Patent ↗A pump-dispensing atomizer includes a dispensing pump with a closure to engage with a container. The dispensing pump includes a pressing button with a booster chamber formed inside, a nozzle with one end extending from the pressing button and a probe formed with at least one section. An interior of the nozzle is formed with a guide chamber, and one end of the guide chamber is connected to the booster chamber. The guide chamber has at least one expanding sub-chamber. After the probe is disposed in the guide chamber, a boosting channel is formed between the expanding sub-chamber and the stepped section. Moreover, the pressure accumulator is mounted on the other end of the nozzle, which is formed with a spraying opening communicated to outer environment. As such, the pressure of liquid flowing in the nozzle will be increased effectively so that liquid is sprayed out with a higher pressure to increase the spraying speed of the liquid.
1. A pump-dispensing atomizer comprising:
a container filled with liquid; and
a dispensing pump including:
a closure to engage with the container;
a pressing button with a booster chamber formed inside;
a nozzle with one end extending from the pressing button, wherein an interior of the nozzle is formed with a guide chamber, the guide chamber has a plurality of expanding sub-chambers, and one end of the guide chamber is connected to the booster chamber;
a probe formed with a plurality of sections, wherein after the probe is disposed in the guide chamber, a plurality boosting channels are formed between the expanding sub-chambers and the stepped sections, respectively; and
a pressure accumulator mounted on the other end of the nozzle, formed with a spraying opening which is communicated to outer environment
wherein a first tapered surface is formed between two adjacent sections and the first tapered surface is formed with a plurality of first flow guide slots.
2. The atomizer as claimed in claim 1 , wherein a second tapered surface is formed between two adjacent expanding sub-chambers and the second tapered surface is formed with a plurality of second flow guide slots.
3. The atomizer as claimed in claim 1 , wherein the number of the expanding sub-chambers is equal to that of the sections.
4. The atomizer as claimed in claim 1 , wherein the sizes of the boosting channels are sequentially enlarged.
5. The atomizer as claimed in claim 1 , wherein a pressure accumulating chamber is formed inside a distal end of the nozzle between the probe and the pressure accumulator.
6. The atomizer as claimed in claim 1 , wherein the pressure accumulator has a plurality of slots formed in a scrolled arrangement on an inner wall thereof.
