Problems solved by technology

[0010] However, this automatic pump has a disadvantage in that the manufacturing cost is increased since the valve-installed outlet pipe is formed separately from the pump body and then assembled to the pump body.

Abstract

The invention disclose a automatic pump whose valve structure is improved, the valve opens and closes the flow path by straight reciprocating motion with the pressure different caused by allowing and stopping for the flowing of the liquid. The inlet and outlet pipes are formed together with the pump body. The valve base and the valve guide component are configured in the outlet pipe and apart from each other with a appointed distance. The valve has one end part supported by the valve base and the other part supported by the valve guide component so that the valve can disport from the valve base for preventing the connecting of the inlet pipe and the outlet pipe. The valve and valve guide component set dividing apparatus for marking the configuration position of the valve and preventing the valve rotating.

Description

technical field [0001] The present invention relates to an automatic pump having an improved structure of a valve that linearly reciprocates to open and close a flow path using a pressure differential induced when fluid flow is allowed and blocked. Background technique [0002] As is well known in the art, a pump is a device that is driven by a motor to transport fluid. An automatic pump is a device for automatically controlling the flow of fluid introduced into and discharged out of the pump. [0003] will refer to figure 1 Describe a conventional automatic pump. figure 1 is a longitudinal sectional view showing a schematic structure of a conventional automatic pump. [0004] refer to figure 1 , the automatic pump has a pump body 11. The pump body 11 includes a first case 12 and a second case 13 which are combined with each other to define a flow path. The inlet 12 a and the outlet 12 b are formed through one side and the other side of the first casing 12 , and the im...
