Title:
LIQUID PUMP
Document Type and Number:
WIPO Patent Application WO/2019/100764
Kind Code:
A1
Abstract:
A liquid pump (100, 200, 300, 400 ,500, 600, 700, 800, 900), comprising a moving unit and a fixed unit, the moving unit capable of moving relative to the fixed unit, thereby pumping out a product; an elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) disposed between the moving unit and the fixed unit, the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) comprising at least one elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931), an elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) applying biasing force to the moving unit so as to cause the moving unit to reset after pumping a product. The liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900) further comprises an elastic mechanism adjustment element, the elastic mechanism adjustment element being capable of moving between a first position and a second position; in the first position, the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a relaxed state, and in the second position, the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a pre-loaded state. By means of providing an elastic mechanism adjustment element, the present invention facilitates pressing down a pressure head (110, 210, 310, 410, 510, 610, 710, 910) during use, and can prevent yield deformation of an elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) caused by long-term stress.
