Powder sprayer

Abstract

A powder sprayer comprises a bottle body, a pump body, a piston and an elastic element and is characterized in that a hollow delivery pipe is arranged in a piston of the pump body, the upper end of the hollow delivery pipe is communicated with a nozzle of a cap, and the lower end of the delivery pipe is communicated with a middle hole in the pump body. The upper end of a connector is connected with the lower end of the pump body, the connector comprises a powder outlet channel communicated with the delivery pipe, a base used for mixing powder and air flow is arranged at the bottom of the powder outlet channel, and a powder inlet is formed and communicated with a bottle body inner cavity. The connector further comprises an air flow channel, an air inlet of the air flow channel is communicated with a piston cavity, and an air outlet is communicated with the base. A manipulator mechanism is arranged in the bottle body inner cavity and at least comprises a manipulator, and the upper end of the manipulator is connected with the cap or the piston through a transmission mechanism. The powder sprayer has the advantages of being simple in structure, convenient and quick to use and good in powder spraying effect.

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, but because the rotation of the gear is relatively simple, the powder in the bottle cannot be completely sprayed out for use, and because the gear is installed in the housing, it occupies a certain space and is sealed. The performance is relatively not the best, resulting in the airflow not being able to fully blow up the powder in the housing, resulting in a decrease in efficiency, and the hollow delivery tube is easily deformed after a long time of use, making it difficult for the dry powder to pass through smoothly, so the structure needs to be further improved
