Abstract
Description
- 1. Field of the Invention
- The present invention relates to a fluid supplying device.
- 2. Description of the Prior Art
- A conventional fluid supplying device has a reservoir for receiving fluid and is driven by manually pumping up or by gas filled into the reservoir for pushing fluid out.
- Some fluid supplying devices can be operated in gas-mode or manually alternatively. However, when operated manually, the reservoir has to communicate with exterior to allow a pressing rod to pumping up. Thus, the reservoir must form a relief hole or other similar structure. On the contrary, when operated in gas-mode, there is no necessity to slide the pressing rod, so the relief hole is unnecessary. In addition, the relief hole may result gas-leakage so that the fluid is difficult to be extracted out. Thus, the relief hole should be closed in advance.
- On the other hand, when operated in gas-mode, the pressing rod may bounce up due to the input gas. The bouncing pressing rod may be dangerous. Even if a positioning device is disposed to position the pressing rod, the pressing rod may bounce up when a user forgets to position it.
- The main object of the present invention is to provide a fluid supplying device which is able to be operated by gas-mode or manually, and the fluid supplying device can block relief hole and prevent pressing rod from bouncing up at the same time.
- To achieve the above and other objects, a fluid supplying device of the present invention includes a reservoir, a cover, an outer tube, an inner tube, a pressing rod, and a positioning handle.
- The reservoir has an opening at o top thereof and a gas inlet. The top of the reservoir further forms a relief hole. The cover is disposed at the opening and is hollow. A side of the cover forms a fluid outlet. An end of the outer tube extends into the reservoir, and an opposite end of the outer tube extends outside the reservoir through the cover. The outer tube communicates with the fluid outlet. The inner tube is disposed in the outer tube, and an end of the inner tube also extends through the cover. The pressing rod is slidably disposed in the inner tube, and an end of the pressing rod away from the reservoir extends outside the cover. An end of the positioning handle is pivotably disposed to the top of the reservoir and is able to pivot between a first position and a second position. The positioning handle further forms a through hole.
- When the positioning handle is located at the first position, an end of the positioning handle away from the reservoir abuts against the end of the pressing rod away from the reservoir so that the pressing rod is unable to move along the inner tube. Also, the through hole is positionally deviated from the relief hole so that the relief hole does not communicate inside the reservoir and exterior therebetween. On the contrary, when the positioning handle is located at the second position, the end of the positioning handle away from the reservoir is away from the pressing rod and does not block the pressing rod so that the pressing rod is able to move along the inner tube. Also, the through hole positionally corresponds to the relief hole so that the relief hole communicates with exterior via the through hole.
- That is, when the positioning handle is located at the first position, the reservoir does not communicate with exterior, and the pressing rod is unmovable. Thus, when gas enters the reservoir via the gas inlet, fluid in the reservoir is sucked out via the outer tube and the fluid outlet. Due to the positioning handle blocking the pressing rod, the pressing rod may not bounce up when gas enters the reservoir. On the other hand, when the positioning handle is located at the second position, the reservoir communicates with exterior, and the pressing rod is not blocked by the positioning handle so that the pressing rod is able to be slid to suck fluid into the inner tube and then to push the fluid in the inner tube into the outer tube. Thus, the fluid in the outer tube can further flow out via the fluid outlet.
- Thereby, the fluid supplying device of the present invention can be operated in gas-mode or manually. Moreover, the relief hole can be closed and the pressing rod can be blocked and be prevented from bouncing up at the same time by a simple operation when the fluid supplying device is operated in gas-mode. Thus, convenience and safety are achieved.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

At this time, the throughhole 611 positionally corresponds to therelief hole 13 so that therelief hole 13 communicates with exterior via the throughhole 611. Specifically, thehandgrip 51 leaves therestriction groove 62 so that thepressing rod 50 is able to move up and down, and the throughhole 611 communicates with therelief hole 13. - In use, to operate in gas-mode, a user needs to move the positioning handle to the first position to restrict the pressing rod and to block the relief hole, and then gas is filled into the reservoir via the gas inlet to push the fluid in the reservoir to enter the outer tube. Thus, the fluid in the outer tube can be further leave the reservoir via the fluid outlet to be available for injecting to other devices. On the other hand, to operate manually, a user needs to move the positioning handle to the second position to release the pressing rod. The fluid in the reservoir can be sucked into the inner tube when the pressing rod is pulled up, and the fluid in the inner tube can enter the outer tube to further leave via the fluid outlet when the pressing rod is pressed down.
- Thereby, the fluid supplying device of the present invention can be operated in gas-mode or manually alternatively and provides a simple mechanism for blocking the relief hole and for preventing the pressing rod from bouncing up at the same time. Even if a user forgets to move the positioning handle to the first position before filling gas into the reservoir, the pressing rod may not bounce up because the relief hole has not been closed. Thus, convenience and safety are both achieved.
