- Therein, the base is formed with a disk having a surrounding wall at its rim. The base has two sets of connecting pipes and each set has two connecting pipes located at two radial ends separately. Two inward arc protrusions are located on inner surface of the surrounding wall at two radial ends separately. Each protrusion is located between two neighboring connecting pipes at each one of the radial ends. And a shaft of the disk is penetrated through an axis hole.
- The rotor is movably set in the surrounding wall. The outer surface of the rotor is stuck to an arc surface of the protrusion. Thus, a pair of flow paths is formed between the surrounding wall and the rotor and is connected with the connecting pipes. An axis rod on an end surface of the rotor penetrates out the base through the axis hole for an outside driver to rotate the rotor. A sliding channel at the opposite end surface of the rotor is set along an axis radial and is penetrated out the outside rim of the rotor at two ends of the sliding channel.
- The sliding block is embedded in the sliding channel with a length shorter than the sliding channel. The part of the sliding channel which extends out of the sliding block forms a transferring space to connect to the flow path. Two ends of the sliding block are closely contacted with an inner surface of the protrusion. And the middle section of the sliding block is concaved to obtain a slot.
- The towing member is embedded in the slot nestling to the slot wall. The towing member is inserted with a positioning rod at the center. And a shaft of the positioning rod is parallel to a shaft of the rotor. The shaft of the positioning rod is located on the line of two protrusions and is deviated from the shaft of the rotor. The sliding block is towed by the towing member to reciprocate a long the sliding channel. Thus, the transferring space is used to transfer fluid.
- The cover unit is covered on the top of the surrounding wall to seal the flow path. And the positioning rod is fixed with the cover unit to position the shaft of the towing member.
- The prior art uses a towing member to reciprocate a sliding block following the rotation of the rotor along a radial path so that fluid in the fluid channel are pumped with sucking and pushing motions. However, the prior art has a complex structure with a running gear (a motor) at the outside. And a big noise is produced when using the running gear. Hence, the prior art does not fulfill users' requests on actual use.
- The main purpose of the present invention is to lessening a component number of a pump; to simplify fabrication and assembly procedures; and to reduce friction noise of vibration.
- To achieve the above purpose, the present invention is a pumping device, comprising a base, a rotating unit, a driving unit and a cover unit, where the base has a containing space; the containing space has a first indentation and a second indentation having a hole separately; the rotating unit is movably set in the containing space; the rotating unit has a channel on an end surface; the channel has a first opening and a second opening corresponding to the first indentation and the second indentation respectively; the driving unit is set in the channel of the rotating unit; the driving unit has a long hole; the cover unit is covered on the containing space; and the cover unit has a shaft on an end surface to movably penetrating through the long hole of the driving unit. Accordingly, a novel pumping device is obtained.
