Description

Inflatable sprayer

Technical Field

The invention relates to the technical field of sprayers, in particular to a manually-inflated type sprayer which is provided with all plastic parts, can be recycled and used at present and is inflated manually.

Background

The canning principle of air cleaner, aerial fog insecticide, makeup ware spraying etc. is all the same, all packs into the sealed can with liquid medicine, lotion, refills high-pressure gas again, and the spray tube stretches to the tank bottoms, opens the liquid outlet through pressing down the nozzle button during the use, receives high-pressure gas's effect, and the liquid medicine becomes the spray form blowout, loosens the finger after, relies on the effect of spring, and the nozzle button recovers, and the liquid outlet is closed. The aerosol spraying can is characterized in that after the can is made, the liquid medicine and the aerosol propellant are filled into the can together, the aerosol propellant generally adopts Freon and the like as refrigerants for air conditioners as the propellant, the aerosol propellant exists in a liquid state in the can under the action of high pressure, when a nozzle is pressed, the propellant in the can is sprayed outwards rapidly due to small external air pressure, the aerosol propellant in the can is vaporized rapidly, meanwhile, the liquid medicine in the can is sprayed out of the can together through a thin tube under the pressure action of the propellant, and the liquid medicine is sprayed into tiny fog drops to be diffused into the air under the action of air flow; since high-pressure gas is used to perform spray-like operation, such spray cans are generally metal cans because of a certain pressure, and can be used only once and cannot be reused, and there is a risk of explosion during transportation or use.

The prior art also adopts a manual air-filling structure, for example, Chinese patent document (publication date: 1/27 1988, publication number: CN 87201243U) discloses a manual air-filling aerosol sprayer. The sprayer is characterized in that an exhaust hole with the diameter of 0.8-1 mm is arranged at the position, close to the spray head, of the liquid guide pipe connected with the spray head, so that liquid flow and compressed air flow can simultaneously enter the spray head, and aerial fog spraying is realized; the handle of the piston rod may be integrated with the reservoir when the piston is pushed uppermost. However, in the technical scheme, the liquid in the tank can be limited in a very small range and cannot contain too much liquid, otherwise the liquid can enter the inner part of the air cylinder in the use process, and the reason why the air exhaust hole is arranged close to the spray head is also the reason.

Chinese patent document (publication date: 11/9/1988, publication number: CN 88201615U) discloses an inflatable plastic aerosol can, the nozzle structure of the aerosol can adopts a lever form and is made into a whole with a nozzle protection cap, the nozzle of the lever structure has reasonable finger force application in use, the purposes of light weight and labor saving can be achieved, and meanwhile, a one-way air inlet valve on an inflatable pump cylinder is formed by combining a conical rubber valve and a plastic pressing ring, so that the effect of tight inflation matching can be achieved. The aerosol can realize the purposes of one-time inflation and continuous spraying, can be repeatedly filled with liquid for use, is in aerosol shape, and can be widely applied to various spraying fields of cosmetics, air disinfection, sanitary disinsection and the like. Although this technical scheme has adopted the structural principle of plastics aerosol canister and one-way inflation valve, although can hold 80% liquid in the jar in the in-service use process, but to one-way admission valve and the requirement of irritating liquid mouthful sealing performance extremely high, sealing performance is poor in the in-service use process, can have the weeping phenomenon, this kind because jar body need bear higher atmospheric pressure, one-way admission valve and seal structure are inefficacy very easily under the effect of atmospheric pressure.

In order to realize the purpose of high-pressure spraying, the liquid filling port of the two technical schemes can only be arranged at one end, namely the bottom, of the tank body, namely the liquid filling port which cannot realize high-pressure spraying in the prior art is arranged above the tank body so as to realize the operation of air filling below the liquid filling from the upper part. This also leads to problems of the conventional nebulizer, such as complicated structure and poor sealing performance.

In the prior art, a hand-held sprayer is also adopted, for example, a Chinese patent document (publication date: 2016, 5, 4, publication number: CN 205199784U) discloses a hand-held sprayer, aiming at providing a hand-held inflator with high inflating efficiency, and the technical scheme of the hand-held inflator is as follows: the kettle comprises a kettle body and a kettle cover, wherein a water suction pipe and a pressure cylinder are arranged in the kettle body, a nozzle connected with the water suction pipe is arranged on the kettle cover, the pressure cylinder is detachably connected to the kettle cover, a piston and an inflating handle connected with the piston are arranged in the pressure cylinder, a water sealing part is arranged at the bottom of the pressure cylinder, and the diameter of the pressure cylinder is 27 mm-31 mm. Although the liquid filling opening of the hand-held sprayer can be arranged at the upper part, the sprayer is complex in structure, an external hand-held inflatable structure is generally a kettle-type structure, the whole sprayer is large in appearance, inconvenient to transport and store, and mostly used for spraying plants and other appliances.

Disclosure of Invention

The invention aims to solve the problems that the sprayer in the prior art cannot simultaneously realize the lower arrangement of an inflation structure arranged on a liquid filling port, and the inflatable structure in the prior art is arranged in liquid, has poor sealing effect, has liquid leakage and the like, the liquid in a bottle body can be filled with 80% of the liquid at most, the utilization rate of the volume in the bottle is limited, and the maximization of space utilization cannot be realized.

The invention adopts the technical scheme that the invention achieves the aim that: an inflatable nebulizer, comprising:
