Dry powder pump

Abstract

The invention relates to a dry powder pump comprising a bottle body, a cap, a piston and an elastic element, wherein an inner cavity of the bottle body is used for containing powder; the cap is connected to a mouth of the bottle body to form a piston cavity; the piston is driven to slide up and down by a head cap and then is limited and installed in the piston cavity to form an air compressing mechanism; and the elastic element makes the piston have a resetting trend. The dry powder pump is characterized in that a one-way valve is arranged in the mouth of the bottle body, an air inlet and the one-way valve is communicated with the piston cavity, and an air outlet of the one-way valve is communicated with the inner cavity of the bottle body; and the upper end of a hollow pipeline is communicated with a nozzle on the head cap, and the lower end of the hollow pipeline passes through the mouth of the bottle body to extend nearby the bottom of the bottle body and is directly or indirectly communicated with the inner cavity of the bottle body. The dry powder pump has the advantages of reasonable and practical structure, favorable sealing performance, convenient operation and use, light weight and convenient carrying and is easy to spray mixed powder and air.

Description

technical field [0001] The invention relates to a dry powder pump which sprays out the powder contained in it, which is similar to a liquid spray gun. It can be used to hold various powders such as talcum powder, prickly heat powder, and cosmetic powder in civil use. It can also be used in industry. It is used to hold various powders such as dyeing powder. Background technique [0002] In traditional habits, sprayers have been widely applied to the packaging and use of liquid products, such as spray cans, foam pumps, and vacuum pumps, but for dry powder products such as prickly heat powder, talcum powder, and even pigment powder. Good packaging and usage methods, they are usually packed in cans or boxes, which are inconvenient to use and need to be used with other tools such as spoons or powder dusters. Moreover, during use, things often happen due to knocking over, causing dry powder to spill All over the world, it pollutes the environment and causes waste. People are eage...

Problems solved by technology

[0002] In traditional habits, sprayers have been widely applied to the packaging and use of liquid products, such as spray cans, foam pumps, and vacuum pumps, but for dry powder products such as prickly heat powder, talcum powder, and even pigment powder. Good packaging and usage methods, they are usually packed in cans or boxes, which are inconvenient to use and need to be used with other tools such as spoons or powder dusters. Moreover, during use, things often happen due to knocking over, causing dry powder to spill All over the place, it pollutes the environment and causes waste. People are eager for a new sprayer-like product suitable for the packaging and use of dry powder products

[0003] Although there are many sprayer structures produced by using the vacuum principle, such as spray cans, foam pumps, vacuum pumps, etc., they are only suitable for liquid products, and cannot meet the requirements of dry powder in structure, and cannot atomize the powder from the container. Therefore, It cannot be directly applied to dry powder products, and the structure needs to be improved.
