The invention relates to an improved structure of a hand-buckling minitype atomizer and a using method thereof, which is designed aiming at solving the technical problem that the existing hand-buckling minitype atomizer has certain limitation for the viscosity of liquid. The improved structure of the hand-buckling minitype atomizer has the key points that the valve top of a valve needle in the atomizer takes on a cone shape, and the valve top of the valve needle is movably matched and sealed with the inner diameter of a piston; a pump body is provided with a pressure discharge hole between a first valve needle sealing rib and a second valve needle sealing rib of the valve needle; the inner and the outer diameters of the pump body are gradually increased in a four-step shape from a glass bead cavity to a pump cavity; a sealing cavity is formed by the piston, the valve needle, a spring, the pump body and a glass bead; when in use, pressure difference is formed between the inside and theoutside of the sealing cavity A; and the liquid is repeatedly circulated under the action of elastic force of the spring and is finally sprayed out. The invention changes the exhaust of the sealing cavity, the instantaneous sealing after the movable sealing part of the piston and the valve needle is opened, and the structure change of liquid introduction when in liquid absorption, leads the liquid with proper high viscosity to be normally atomized for use, and is applicable to improving the structure of the existing hand-buckling minitype atomizer and similar products.
Description
technical field [0001] The invention relates to a micro-sprayer, which is an improved structure of a hand button type micro-sprayer and a using method thereof. Background technique [0002] At present, there are many micro-sprayers on the market. These micro-sprayers atomize and spray the liquid in the container by pressing the wrench with the hand button. Depending on the composition of the liquid in the container, they can be used in gardening, hairdressing, beauty and other fields. Its working principle is: the piston moves in the pump body, so that the gas in the pump body flows, the pressure becomes smaller, the pressure outside the pump body remains unchanged, and a pressure difference is generated inside and outside the pump body, and the liquid is guided out of the pump body through the pressure difference. Instant atomization when encountering high-speed airflow. For example, the patent No. ZL200610050655.5 published in the Chinese patent literature, the date of au...
