Hand-pressing liquid suction pump

Abstract

The invention discloses a hand-pressing liquid suction pump which comprises a piston shell body, wherein a pump shell is fixedly arranged at one end of the piston shell body; a valve bead is arranged in the pump shell; a piston cover is fixedly arranged at the end, away from the pump shell, of the piston shell body; and a liquid outlet pipe is fixedly arranged on one side of the outer part of the piston shell. Through the spring liquid suction mode, the accuracy of the liquid suction flow can be ensured according to the spring damping effect; compared with an existing hand-pressing liquid suction pump, the hand-pressing liquid suction pump provided by the invention has the advantages that the spring liquid suction mode is matched with the use of a piston head optimized to be an umbrella-shaped structure, so that the self-suction flow can be increased, and then the pressing stroke can be shortened by one third based on the same liquid suction flow; in the actual application process of the hand-pressing liquid suction pump, the self-suction of two hundred milliliters at a time can be achieved, and thus no repeated pressing suction action of a cleaning user is needed; meanwhile, the proportional mixing can be completed as required; and consequently, the hand-pressing liquid suction pump is relatively high in usability, and worthy of popularization and use.

Description

technical field [0001] The invention relates to the technical field of liquid suction pumps for washing liquid bottles, in particular to a hand-pressed liquid suction pump. Background technique [0002] Washing liquid is a cleaning product in a liquid state used to wash clothes or clean utensils or clean furniture. It adopts a variety of new surfactants, which has strong detergency, easy rinsing and no irritation to the skin. It is most suitable for washing kitchen utensils, furniture, and fruits and vegetables. [0003] At present, shops and large venues mostly use concentrated washing liquid with water as the main cleaning method. Although there is a ratio requirement for the mixing of washing liquid and water, the single suction volume of the existing suction pump is only 30ml in actual application. At the same time, it adopts the form of spring and ball check valve, which makes its self-priming flow low. The main method of use is to absorb liquid by pressing, which can...

Problems solved by technology

[0003] At present, shops and large venues mostly use concentrated washing liquid with water as the main cleaning method. Although there is a ratio requirement for the mixing of washing liquid and water, the single suction volume of the existing suction pump is only 30ml in actual application. At the same time, it adopts the form of spring and ball check valve, which makes its self-priming flow low. The main method of use is to absorb liquid by pressing, which cannot accurately absorb the liquid flow. At present, the liquid suction flow of the suction pump is still controlled by the pressing stroke. The longer the pressing stroke, the more the suction flow will be. As a result, due to the structural defects of the suction pump, the current suction pump cannot accurately control the suction volume, and the flow rate of a single pump body is low, so that the cleaning staff needs to The disadvantage of being unable to complete the proportion mixing as required by pressing and absorbing multiple times
