The thickness of the main body 431 and the lug portion 432 is smaller than the width of the second cut groove 42, so that the second valve plate 43 is not positioned in the second cut groove 42, and can deflect when subjected to pressure . When the main body 431 of the second valve plate 43 deflects against the second step 413, the small diameter section 411 of the second passage 41 is closed by the main body 431; and when the main body 431 of the second valve plate 43 When it deflects away from the second step portion 413, the second passage 41 is opened.

Referring to Fig. 8, a pumping space 5 is defined between the first valve plate 34 and the second valve plate 43, and the volume of the pumping space 5 can vary with the volume of the first paddle tube 1 and the second paddle tube 2. The relative movement of 2 changes; in detail, when the first paddle tube 1 and the second paddle tube 2 are pulled apart so that the first tube head 3 and the second tube head 4 are relatively far away, the pumping space 5 becomes larger, otherwise the drawing space 5 becomes smaller. A buffer spring 6 is arranged between the first tube head 3 and the second tube head 4 to avoid direct collision between the two.

Referring to Figure 1, the second paddle tube 2 is connected to a paddle plate 7 at one end away from the first tube head 3 for paddling to generate thrust to propel the boat forward. The paddle plate 7 includes a plate portion 71 and a connecting portion 72. The plate portion 71 is provided with a groove 711, and the connecting portion 72 is embedded in the groove 711 and fixed on the plate portion 71 accordingly.

Furthermore, the paddle board 7 can be as shown in FIG. 3, the connecting portion 72 has one end of the water outlet 722 extending to the end of the paddle board 7, so that the water outlet 722 is located on the edge of the paddle board 7.

When this creation is actually used to draw water on a ship, first the second paddle tube 2 is inserted into the first paddle tube 1 as shown in Figure 8, that is, the second valve plate 43 is close to the first valve plate. 34 to reduce the pumping space 5, and immerse the pumping port 32 in the water in this position. Then pull the second paddle tube 2 as shown in Figure 9, that is, make the second valve plate 43 away from the first valve plate 34 to increase the pumping space 5. At this time, the pumping space 5 is increased. Therefore, the pressure of the pumping space 5 is reduced, and the second valve plate 43 is driven by the pressure to deflect in the direction of the pumping space 5 to abut against the second step 413, thereby closing the second passage 41 in order to ensure the low pressure state of the pumping space 5; on the other hand, the pressure also drives the first valve plate 34 to deflect in the direction of the pumping space 5 and leave the first step 313, thereby opening the first Channel 31. Combining the changes in the actions of the above-mentioned components, the water on the ship can be sucked into the first passage 31 from the pumping port 32 based on the pressure change of the pumping space 5, and enter the pumping space through the opened first valve plate 34 5.

Then, as shown in Figure 10, push the second paddle tube 2 into the first paddle tube 1, that is, make the second valve plate 43 approach the first valve plate 34 to reduce the pumping space 5. At this time, because the pumping space 5 is reduced, the pressure of the pumping space 5 increases, and the pressure drives the first valve plate 34 to deflect in the direction away from the pumping space 5 to resist the first stage. According to this, the first passage 31 is closed; on the other hand, the pressure also drives the second valve plate 43 to swing away from the pumping space 5 and leave the second step 413, thereby opening the first Two channel 41. Combining the movement changes of the above components, the water in the pumping space 5 is driven based on pressure changes, but is blocked by the first valve plate 34 and cannot flow toward the pumping port 32, but passes through the opened second The valve plate 43 enters the second paddle tube 2 and is discharged from the water outlet 722.

When using this creation to implement the aforementioned water pumping action, as shown in Figure 11, the user can easily sit on the boat, as long as the action of pulling the second oar tube relative to the first oar tube can complete the water pumping, and then The action of pushing the second propeller tube into the first propeller tube can complete the drainage. Repeated implementation of these two actions can continuously absorb the water from the boat and drain it out of the boat. There is no need to bend over and get up repeatedly in the process. Effectively reduce physical exertion, and quickly complete water drawing and drainage, which is very convenient to use.

However, the disclosure of the above embodiments is only used to illustrate the creation, not to limit the creation, and the replacement of equivalent components should still belong to the scope of the creation.

In summary, those skilled in the art can understand that this creation can indeed achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, so that the application is filed in accordance with the law.
