Dry powder sprayer

Abstract

A dry powder sprayer comprises a bottle body accommodating dry powder, and is characterized by comprising a hollow conveying pipe, a connector, a group of manipulators and a push rod, wherein the upper end of the hollow conveying pipe is communicated with the nozzle of a head cap; the lower end of the hollow conveying pipe is fixed on a pillar body of a pump body, and is communicated with a central hole; the upper end of the connector is butted with the lower end of the pump body in a sealed manner; a powder discharge passage coaxially communicated with the conveying pipe is arranged in the middle of the connector; a base used for mixing powder and airflow is arranged at the bottom of the powder discharge passage; a powder inlet is formed in the side part of the base, and is communicated with the inner chamber of the bottle body; the manipulators are arranged at the side part of the connector; the upper end of each manipulator is rotationally mounted onto the connector; the lower end of the manipulator is matched with the powder inlet of the base; the push rod is movably inserted into an inner hole in the conveying pipe; the upper end of the push rod is connected with a piston; the lower end of the push rod penetrates the central hole of the pump body and is arranged in the powder discharge passage of the connector; the manipulators push dry powder in the bottle body into the base under the driving of the push rod. The dry powder sprayer has the advantages that the structure is simple and reasonable; the use is convenient and fast; the sealing performance is high; the possibility of blockage is low.

Description

technical field [0001] The invention relates to a sprayer, in particular to a dry powder sprayer capable of spraying the powder contained in the sprayer. Background technique [0002] At present, there are many liquid sprayers on the market, but for dry powder products such as talcum powder and prickly heat powder, etc., they are generally packed in cans or boxes, and need to be used with a spoon or powder tip, or there are multiple devices on the mouth of the tank. There is a small hole for pouring, and the dry powder is poured onto the powder head through the small hole during use. These several methods are very inconvenient to use, and it is easy to cause dry powder to spill accidentally, which not only pollutes the environment, but also causes waste. Therefore, sprayers for dry powder products have also appeared now, such as the Chinese patent "A Kind of Dry powder pump", which includes: a bottle body, the inner cavity of the bottle is used to hold powder; a cover, conn...

AI Technical Summary

Problems solved by technology

With this structure, it is easy to make the powder and gas mixed and sprayed out of the dry powder pump, and the sealing performance is good, but because the rotation of the gear is relatively simple, the powder in the bottle cannot be completely sprayed out, and the hollow delivery tube is easy to deform after a long time of use. , so that the dry powder cannot pass through smoothly, so the structure needs to be further improved
