This creation is a kind of Water draw-off pump,It includes drawing pressure-sucking ball,This draws pressure-sucking ball both ends and is separately connected a water inlet pipe component and an outlet pipe component,The end of the water inlet pipe component is equipped with a filtration members,The flow control member system sets the what outlet pipe component and adjustment water yield,The water inlet pipe component what neighbouring draw enters water one-way valve equipped with one at pressure-sucking ball,The outlet pipe component what neighbouring draw goes out water one-way valve equipped with one at pressure-sucking ball,Filtration members are passed through by water with siphon principle using pressure-sucking ball is drawn,It flows through water inlet pipe component and flows out the outlet pipe component,The Water draw-off pump uses the control that draws water singly flowed to,It makes overall structure simplified and manufacturing cost is effectively reduced.本創作係一種汲水器,其包含有一汲吸壓球,該汲吸壓球兩端分別連接一入水管組件及一出水管組件,該入水管組件的末端設有一過濾件,該流量控制件係設於該出水管組件且調整出水量,該入水管組件於鄰近汲吸壓球處設有一入水單向閥,該出水管組件於鄰近汲吸壓球處設有一出水單向閥,利用汲吸壓球以虹吸原理讓水通過過濾件,流經入水管組件且流出該出水管組件,該汲水器採用單流向的汲水控制,讓整體結構簡化並有效降低製造成本。
