Title
(EN) AN EMULSION PUMP WITH EXTERNAL SPRING
(FR) POMPE À ÉMULSION AVEC RESSORT EXTERNE
(ZH) 弹簧外置式乳液泵
Abstract
(EN)
An emulsion pump comprises a gland; a connecting duct which connects with said gland and which is provided with an upper one-way valve; a toothed connector which is provided with a first connection structure and a second connection structure, wherein said first connection structure is used to engage with a bottle; a cylinder with its upper part provided with a connection structure to engage with the second connection structure of said toothed connector while its lower part provided with a lower one-way valve; a piston which moves inside said cylinder and connects with said connecting duct with its upper part; and a spring for resetting said piston, whose upper part abuts on said connecting duct while its lower part rests on the spring seat provided in said cylinder. The emulsion pump has an external spring which does not contact with the emulsion. The emulsion pump can be made with very simple structure and can be manufactured with few components, therefore can greatly improve the production efficiency and reduce the cost.

La présente invention concerne une pompe à émulsion qui comprend un fouloir ; une conduite de raccord qui se raccorde audit fouloir et qui est pourvue d'une soupape de non-retour supérieure ; un raccord denté qui est pourvu d'une première structure de raccord et une seconde structure de raccord, ladite première structure de raccord étant utilisée pour entrer en prise avec une bouteille ; un cylindre avec sa partie supérieure pourvue d'une structure de raccord pour entrer en prise avec la seconde structure de raccord dudit raccord denté alors que sa partie inférieure est pourvue d'une soupape de non-retour inférieure ; un piston qui se déplace à l'intérieur dudit cylindre et se raccorde à ladite conduite de raccord avec sa partie supérieure ; et un ressort pour remettre ledit piston, dont la partie supérieure prend appui sur ladite conduite de raccord alors que sa partie inférieure repose sur le siège de ressort prévu dans ledit cylindre, dans sa position initiale. La pompe à émulsion comporte un ressort externe qui n'entre pas en contact avec l'émulsion. La pompe à émulsion peut être réalisée avec une structure très simple et peut être fabriquée avec moins de composants, et donc peut énormément optimiser le rendement de production et réduire les frais.
