Abstract
This invention relates to a liquid jet blower that operates as an aerosol sprayer without using any pressurized gas. This invention is intended to provide a liquid jet blower which is free from clogging of the nozzle and undesired flows of the liquid outside its container. To that end, structure is provided for relieving any excessive pressure within its pressure chamber and transferring any remaining liquid to a small chamber specifically arranged within the blower.
Claims20
A liquid jet blower comprising:
- a nozzle having an injection pipe disposed in communication with a tubular cap;
- a container movably connected to said tubular cap, said container having a pressure chamber;
- a plunger that reciprocates between upper and lower positions within said pressure chamber of said container, said pressure chamber being capable of supplying said nozzle with pressurized fluid,
- means for reciprocating said plunger from said upper position to said lower position upon movement of said container with respect to said tubular cap whereby pressurization of said pressure chamber occurs independently of actuation of said nozzle;
- and
- means for at least one of relieving excess pressure from an inside of the pressure chamber into the container when the plunger is moved to said lower position, providing ambient air to said container when the plunger is moved to the upper position, and removing excess pressurized fluid from at least one of said injection pipe and said nozzle.

A liquid jet blower comprising:
- a tubular cap;
- a nozzle disposed in communication with said tubular cap;
- a container for storing pressurized fluid having a pressure chamber, said container being connected to said tubular cap;
- a plunger that reciprocates between upper and lower positions within said pressure chamber of said container, said pressure chamber being capable of supplying said nozzle with said pressurized fluid,
- means for reciprocating said plunger from said upper position to said lower position upon movement of said container with respect to said tubular cap whereby pressurization of said pressure chamber occurs independently of actuation of said nozzle;
- and
- means for relieving excess pressure from an inside of the pressure chamber into the container when the plunger is moved to said lower position.

A liquid jet blower comprising:
- a tubular cap;
- a nozzle disposed in communication with said tubular cap;
- a container for storing pressurized fluid, said container being rotatably connected to said tubular cap;
- a plunger that reciprocates between upper and lower positions within a pressure chamber of said container, said pressure chamber being capable of supplying said nozzle with said pressurized fluid, said plunger being reciprocated between said upper and lower positions upon rotation of said container with respect to said tubular cap;
- and
- a cam tube rigidly connected to said plunger, said container and said tubular cap being relatively rotated to cause the cam tube, and therefore the plunger, to reciprocate, the cam tube further includes a continuous slot having vertical and inclined sections, and said relative rotation causes ball bearings located between said cam tube and an inner surface of said tubular cap to engage said inclined sections thereby moving the plunger to the upper position and drawing said pressurized fluid into said pressure chamber.
