Wash bottle

Abstract

The invention provides a wash bottle which comprises a foot-operated inflator, an air tap pipe, an air inlet pipe, a stainless steel wash bottle, a wash bottle cover, a drain pipe, a connecting pipe and a water valve, wherein the water valve includes a circular plug, a liquid delivering hole, a water valve vertical tube, a spring, a water valve transverse tube end cap, a wedge, a spacing fixing orifice, a chute, a water valve transverse tube, a pressing handle and a cross-like valve tube. According to the invention, the wash bottle realizes flushing of vessels with a large volume at a variety of angles, especially flushing of containers with a large volume, frequency of liquid supplementation is substantially reduced, and powerful water flow can wash out solid or liquid difficult to wash; holding capacity of the wash bottle for a solution is 60 times of that of a common wash bottle, so frequency of supplementing liquid into the wash bottle is substantially reduced; foot-operated pressing is used to replace hand-operated extrusion, so the velocity of water flow is increased, labor intensity of operation personnel is greatly reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to a washing bottle, which is suitable for the operation of a large number of samples in a laboratory and which is washed at different angles, and belongs to the technical field of experimental instruments. Background technique [0002] The wash bottle is used for the quantitative transfer of the solution, as well as the washing and transfer of the precipitate. In laboratories in the fields of environment, chemistry, chemical industry, metallurgy, and geology, the bottle is used for cleaning a small amount of multiple precipitations, transferring solutions, rinsing solvents, and distilling solutions to a certain volume when preparing solutions. The commonly used washing bottle is extruding type at present, is made up of plastic narrow mouth bottle and bottle mouth device outlet pipe. When the bottle body is inclined to a certain angle so that the lower mouth of the conduit is exposed to the liquid surface, the bottle wash canno...

AI Technical Summary

Problems solved by technology

When the bottle body is tilted to a certain angle so that the lower mouth of the catheter is exposed to the liquid surface, the washing bottle cannot be used normally, so the washing bottle can only be rinsed at a certain angle, which is difficult to achieve when it needs to be rinsed from bottom to top

In addition, squeeze-type bottle washing uses the operator to apply pressure to the washing bottle by hand to make the water flow out, which increases the labor intensity of the operator.

Commonly used washing bottles can only hold 500mL of water. When washing a large number of samples or utensils, it is necessary to continuously add water, which is time-consuming and labor-intensive.
