Problems solved by technology
[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.

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] Implement Example 1, such as Figure 1-3 Shown is a dry powder pump, which includes a bottle body 1, a cover 2, a piston 3, an elastic element, a piston rod 4, a one-way valve 5, a delivery pipe 6, a mixing chamber seat 7, a gear 8, a gear connecting rod 9, etc. The main parts, the bottle body 1 is hollow, and its inner cavity is used to hold powder such as talcum powder or prickly heat powder. In order to facilitate the dry powder in the bottle to be used up as much as possible, the bottom of the bottle body 1 is in a concave arc shape, and the bottom of the bottle body 1 is covered The base of the bottle body is connected, the bottle body 1 properly leaves space, the cover 2 is installed on the upper part of the bottle body 1 through threaded connection, and the sealing ring 10 is lined between the cover 2 and the mouth of the bottle ...

The invention relates to a powder stirring mechanism of a dry powder pump, comprising a piston rod, a pipeline and a gear connecting rod. The powder stirring mechanism is characterized in that the piston rod is hollow and does an up-and-down motion by the fit of a head cap and an elastic element; the upper section of the pipeline is slidably spliced and connected with the middle lower section of the piston rod; the upper end of the gear connecting rod is connected with the middle lower part of the piston rod, and the lower end of the gear connecting rod is rotationally and eccentrically connected together with the upper end of the gear; the gear is rotationally installed in the opening position at the lower end of the pipeline or in the opening position of a mixed cavity seat; and the upper end of the mixed cavity seat with an air inlet is connected with the pipeline. The invention 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 powder dialing mechanism of a dry powder pump, which is filled with powder inside and sprayed out. It is similar to a liquid spray gun. In civil use, it can be used to hold various powders such as talcum powder, prickly heat powder, and cosmetic powder. On the one hand, it can also be 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 ...
