Manual spraying bottle good in air tightness and convenient to press

Abstract

The invention relates to the technical field of disinfection and sterilization, and discloses a manual spraying bottle good in air tightness and convenient to press. The manual spraying bottle comprises a spraying bottle body, wherein a bottle cap is movably connected to the top of the spraying bottle body. According to the manual spraying bottle good in air tightness and convenient to press, a button is pressed, a piston piece is driven by a linkage rod to move, and liquid in a water storage chamber is sprayed out of the bottle through a second one-way valve; and when the button is released,a spring drives the button to move leftwards, the piston piece is driven by the linkage rod to move, the liquid in the spraying bottle body can be automatically sucked through a first one-way valve due to pressure in a storage chamber, and therefore the effect of saving labor is achieved. In the normal state, the liquid contained in the water storage chamber blocks air from making contact with theinterior of the spraying bottle body, air pressure leakage cannot be caused, and the air tightness cannot be affected; when the spraying bottle body is used, a first water inlet cannot make contact with air, and therefore air cannot make contact with the interior of the spraying bottle body, and the advantage of being good in air tightness is achieved.

Description

technical field [0001] The invention relates to the technical field of disinfection and sterilization, in particular to a manual spray bottle with good airtightness and convenient pressing. Background technique [0002] Spray bottles, originally known as spray cans, first appeared during World War II. At that time, the number of deaths due to diseases such as malaria was far greater than the number of casualties on the battlefield. At that time, people began to put disinfectants into spray cans and spray them with spray cans. For disinfection and sterilization, people used a gas called chlorofluorocarbons in spray tanks for spraying, but this gas was harmful to the environment, and then gradually developed into other types of sprayers, manual sprayers are one of them One, the manual sprayer does not need to fill in the gas of chlorofluorocarbons when performing disinfection and sterilization, so that it will not pollute the environment, and is very popular among people.
