Aspiration-type spray system

Abstract

An aspiration-type spray system preventing from leaking out of the fluid from the fluid container in transport includes a spraying mechanism (31), a gas cylinder (21), and a chamber (15) for containing fluid to be sprayed. The spraying mechanism (31) aspirates and sprays the fluid contained in the chamber (15) by spouting a gas from the gas cylinder (21). The spraying mechanism (31) includes a cylinder-connecting member (40) connected to the stem (22) of the gas cylinder (21), a fluid-connecting member (45) connected to the fluid chamber (15), and an actuator (35) for hand-operated spraying. The fluid-connecting member (45) is provided with an open / close valve, and the operation of the actuator (35) not only opens the open / close valve of the fluid-connecting member but presses the stem (22).

Description

technical field [0001] This invention relates to suction injectors. Background technique [0002] Conventionally, liquid injectors can be roughly divided into the following three types. The first type is represented by an aerosol container, which accommodates the spray gas and the sprayed object in the same pressure container, and discharges the sprayed object in the form of mist or mousse while spraying the spray gas. The second type is to make the pressure vessel into a double-layer container, and make the inner container into a soft container, which contains the sprayed object inside, and on the other hand, contains high-pressure gas on the outside, thus, the inner soft container Pressurize, and use its pressure to spray the object to be sprayed. The third type is a suction type sprayer, which has: a spraying gas cylinder connected to the spraying mechanism part, and an injected object receiving chamber connected to the spraying mechanism part separately from the sprayi...

Problems solved by technology

However, in this sprayer, since the object container to be sprayed is arranged in front of the spray gas cylinder, if the object container to be sprayed is too large and heavy, the center of gravity when holding it will be moved forward, or the object to be sprayed will be pushed forward. The object container becomes an obstacle, which deteriorates the operability

[0004] The sprayer described in Patent Document 2 is provided with an accommodating chamber for the object to be sprayed on the spraying mechanism (aerosol head) of the aerosol container as a spraying gas cylinder, and the size of the accommodating chamber is limited by the size of the aerosol head, so it cannot be used An overly large housing, even if it is barely designed to be large, will skew the entire weight balance upwards, deteriorating the stability or operability of the setup

[0005] In the injector described in Patent Document 3, the object container to be sprayed is arranged at the lower part of the injection gas cylinder, and the pipe connecting the injection mechanism to the object container must traverse the pressure gas cylinder and lead to the pressure gas cylinder. below, making the structure complex

[0006] In addition, in the injector described in the above-mentioned patent documents, there is no mechanism for sealing the container of the object to be injected, and there is a danger of the object to be injected leaking from the container of the object to be injected during transportation.
