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.
