초록 ▼

A one way valve is revealed. The one way valve includes a valve seat and a valve member supported by the valve seat. A hole is mounted at a center of the valve base while an outer circular base is disposed around the hole and an inner circular base is arranged at a center of the hole. The inner circular base has a circular sidewall around an opening. At least one gap is radially formed on the circular sidewall and the gap is vertically penetrating the circular sidewall. The valve member consists of a membrane portion and a rod portion extended from one side of the membrane portion. Thereby the rod portion is passed through the gap of the inner circular base to be set into the opening of the inner circular base.

1. A one way valve comprising: a valve seat having an outer circular base disposed around a hole, an inner circular base arranged at a center of the hole and having a circular sidewall around an opening while the opening and the hole are concentric, wherein a longitudinal section of the opening of the inner circular base is funnel shape, and a plurality of ribs that are radially extended from the circular sidewall to an inner sidewall of the outer circular base for dividing the hole into plurality of equal openings;a valve member disposed on the valve seat for opening and closing the hole and having:a membrane portion in contact with a part of the outer circular base around the hole; the membrane portion is in contact with the whole circumference of the hole while in a first state thereof so as to close the hole on the valve seat; while in a second state, at least a part of the membrane portion originally in contact with the outer circular base is apart from each other, allowing at least one fluid to pass through the hole of the valve seat; the membrane portion is switched from the first state to the second by deformation thereof;a rod portion having a fixing end connected to one side of the membrane portion, and a moveable end opposite to the fixing end;a positioning part is disposed on the rod portion of the valve member and adjacent to the movable end of the rod portion, the positioning part is projecting outward from an outer surface of the rod portion;a cross section of the positioning part is in a shape selected from the group consisting of rectangular, round or tapered inwardly in the direction from the fixing end to the movable end, and able to be passed through one of the plurality equal openings;wherein at least one gap is set radially on the circular sidewall of the inner circular base of the valve seat and is vertically penetrating the circular sidewall to allow the rod portion of the valve member to be passed through radially; the rod portion of the valve member and the positioning part to first inserted into the one of the plurality equal openings axially and then the rod portion radially passed through the gap and mounted into the opening of the inner circular base so that the rod portion is axially retained between the membrane portion of the valve member and the positioning part. 2. The one way valve as claimed in claim 1, wherein the valve seat further includes a flange projecting radially from an outer wall of the outer circular base. 3. The one way valve as claimed in claim 1, wherein the gap of the inner circular base of the valve seat is located between the two adjacent ribs. 4. The one way valve as claimed in claim 1, wherein a width of the gap of the inner circular base of the valve seat is smaller than an outer diameter of the rod portion of the valve member. 5. The one way valve as claimed in claim 1, wherein two sides of the gap of the inner circular base of the valve seat are parallel as viewed axially from the opening of the inner circular base. 6. The one way valve as claimed in claim 1, wherein the gap of the inner circular base of the valve seat is funnel-shaped as viewed axially from the opening of the inner circular base. 7. The one way valve as claimed in claim 1, wherein at least one ring is arranged at and projecting from one side of the membrane portion.
