Abstract

A fluid supply device includes a base member including an end plate and a rod perpendicularly extending from a first end of the end plate and defining a first channel axially and a through slot radially, a container attached to a second end of the end plate opposite to the first end and defining a second channel to contain fluid, a pushing member slidably received in the first channel and the second channel, an actuating sleeve threadedly engaging with the rod, and a fixing member attached to the actuating sleeve and extending through the through slot and the pushing member. The actuating sleeve is rotated to drive the pushing member to slide in the first channel and the second channel to push the fluid.

First claim

What is claimed is:

1. A fluid supply device comprising:
a base member comprising an end plate and a rod perpendicularly extending from a first end of the end plate, the rod axially defining a first channel, which extends through the end plate and radially defining a through slot;
a container attached to a second end of the end plate opposite to the first end, in the container defining a second channel to contain fluid therein, wherein the second channel is in alignment with the first channel of the base member;
a pushing member slidably received in the first channel and the second channel;
an actuating sleeve configured to threadedly engage with the rod; and
a fixing member attached to the actuating sleeve and extending through the through slot and the pushing member;
wherein the actuating sleeve is rotated to drive the pushing member to slide in the first channel and the second channel to push the fluid.

2. The fluid supply device of claim 1 , wherein the pushing member comprises a first post and a second post connected to the first post.

3. The fluid supply device of claim 1 , wherein an elastic member is configured to be sandwiched between the fixing member and the end plate.

4. The fluid supply device of claim 3 , wherein a gasket member is configured to be attached to the fixing member and be placed around the rod.

5. The fluid supply device of claim 4 , wherein a slit is radially defined in the gasket member for the fixing member extending through.

6. The fluid supply device of claim 1 , wherein the rod comprises an external threaded portion, the actuating sleeve comprises a connecting sleeve formed at one end thereof, a threaded hole is defined in the connecting sleeve to threadedly engage with the external threaded portion of the rod.

7. The fluid supply device of claim 6 , wherein the container comprises an output tube formed at an end thereof away from the base member and a cylindrical member received in the container, the second channel is axially defined in the cylindrical member and in alignment with the output tube.

8. The fluid supply device of claim 7 , wherein a pair of tabs extends outward from container to be attached to the end plate.

9. The fluid supply device of claim 8 , wherein the end plate comprises a fixing portion to be attached to the pair of tabs.

10. The fluid supply device of claim 6 , wherein a rotating sleeve is placed around the actuating sleeve to rotate the actuating sleeve.

11. The fluid supply device of claim 10 , wherein a groove is axially defined in an outer side of the actuating sleeve, and a bar axially extends from an inner side of the rotating sleeve to slidably engage in the groove.

12. The fluid supply device of claim 10 , further comprising a cover configured to be attached to an end of the rod away from the end plate, wherein the cover abuts against the actuating sleeve and the rotating sleeve.

13. The fluid supply device of claim 12 , further comprising an elastic member configured to be sandwiched between the cover and the connecting sleeve of the actuating sleeve.

14. The fluid supply device of claim 12 , wherein an outer side of the rotating sleeve near the cover defines a plurality of evenly distributed scale lines, and an indicator is formed at an outer side of the cover.
