Technical Field
[0001] This utility model relates to the field of water pump technology, and in particular to a rod-shaped water pump that is easy to use for dredging. Background Technology
[0002] Water pumps are a commonly used tool for pumping water. Among them, the rod-type water pump is a lightweight pump that has emerged in recent years, suitable for pumping clean water, sewage, oil, and other liquids in yards and outdoor areas. The rod-type water pump has a straight rod shape with a connecting pipe in the middle. The pump is fixed to the lower end of the connecting pipe, while the power supply and outlet are connected to the upper end. The pumped liquid is discharged through the outlet after passing through the connecting pipe. It is convenient to use and easy to transport. However, when dredging ponds or other areas that haven't been cleaned for a long time, existing rod-type water pumps cannot effectively remove the silt deposited at the bottom. This necessitates the user to prepare additional tools for dredging, causing inconvenience. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a rod-shaped water pump that is easy to use for dredging.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rod-shaped water pump for easy dredging, including a mounting base. The upper end of the mounting base is used to fix the power supply box of the rod-shaped water pump, and the lower end is used to fix the connecting pipe of the rod-shaped water pump. A shaft seat is fixed or integrally provided on the mounting base. The shaft seat is provided with an inlet and an outlet. The inlet is connected to the connecting pipe, and the outlet is connected to the outside. A fan is fixedly provided inside the mounting base. The fan is electrically connected to the power supply of the rod-shaped water pump. An air inlet is provided on the shaft seat. A mode conversion mechanism is provided inside the shaft seat to realize the blowing or pumping of water by the rod-shaped water pump.
[0005] Furthermore, the mode conversion mechanism includes a hollow rotating shaft, which is inserted into and rotatably connected to the bearing seat. A first through hole, a second through hole, and a third through hole are sequentially arranged on the circumferential surface of the rotating shaft, spaced apart along the circumferential direction. These three through holes are sealed to the bearing seat. When the rotating shaft is rotated, and the first through hole is aligned with the air inlet and the third through hole is aligned with the water inlet, the rod-shaped water pump is in air-blowing mode, and the water outlet is closed. When the second through hole is aligned with the water inlet and the third through hole is aligned with the water outlet, the rod-shaped water pump is in water-pumping mode, and the air inlet is closed.
[0006] Furthermore, an elastic sealing sleeve is provided between the rotating shaft and the bearing seat. The sealing sleeve is fixed inside the bearing seat. The sealing sleeve is provided with three fourth through holes that correspond one-to-one with the air inlet, water inlet and water outlet. The rotating shaft and the sealing sleeve are interference-fitted and can rotate relative to each other.
[0007] Furthermore, a positioning rib is integrally provided on the outer circumferential surface of the sealing sleeve, and a positioning groove is provided on the inner circumferential surface of the bearing seat. The positioning rib is embedded in the positioning groove to restrict the rotation of the sealing sleeve.
[0008] Furthermore, a first touch switch and a second touch switch are fixedly installed on the mounting base, and an touch protrusion is integrally provided on the rotating shaft. A limit groove is provided on the circumferential surface of the shaft seat, and the touch protrusion extends out of the limit groove. When the rod-shaped water pump is in the air blowing mode, the touch protrusion contacts the first touch switch; when the rod-shaped water pump is in the water pumping mode, the touch protrusion contacts the second touch switch. The first touch switch is electrically connected to the power supply of the fan and the rod-shaped water pump, and the second touch switch is electrically connected to the power supply and the water pump of the rod-shaped water pump.
[0009] Furthermore, a knob is fixedly provided at the outer end of the rotating shaft.
[0010] Compared with the prior art, the advantages of this utility model are that the mounting base is equipped with a fan and the shaft seat is equipped with a mode conversion mechanism, which enables the rod-shaped water pump to have two modes: air blowing and water pumping. When dredging is required, the mode conversion mechanism can be used to put the rod-shaped water pump into air blowing mode to blow air into the sludge at the bottom of the water to agitate the sludge. Then, the rod-shaped water pump can be switched to water pumping mode to pump out the sewage containing sludge. This achieves two uses in one device, is convenient to use, and also saves equipment costs. Attached Figure Description

The upper end of the mounting base 1 is fixed to the power supply box 2 of the rod-shaped water pump, and the lower end is fixed to the connecting pipe 3 of the rod-shaped water pump. A shaft seat 4 is integrally provided on the mounting base 1. The shaft seat 4 is provided with an inlet 41 and an outlet 42. The inlet 41 is connected to the connecting pipe 3, and the outlet 42 is connected to the outside. A blower 5 is fixedly installed inside the mounting base 1. The blower 5 is electrically connected to the power supply of the rod-shaped water pump. An air inlet 43 is provided on the shaft seat 4. A mode conversion mechanism is provided inside the shaft seat 4 to realize the blowing or pumping of water by the rod-shaped water pump. The mode conversion mechanism includes a hollow rotating shaft 6, which is inserted into the shaft seat 4 and rotatably connected to the shaft seat 4. The circumference of the rotating shaft 6 is sequentially... The pump is equipped with a first through hole 61, a second through hole 62, and a third through hole 63 spaced apart along the circumference. An elastic sealing sleeve 7 is provided between the rotating shaft 6 and the shaft seat 4, fixed inside the shaft seat 4. The sealing sleeve 7 has three fourth through holes 71 corresponding to the air inlet 43, water inlet 41, and water outlet 42. The rotating shaft 6 and the sealing sleeve 7 are interference-fitted and can rotate relative to each other, allowing the first through hole 61, second through hole 62, and third through hole 63 on the rotating shaft 6 to seal against the shaft seat 4. When the rotating shaft 6 is rotated, and the first through hole 61 is aligned with the air inlet 43 and the third through hole 63 is aligned with the water inlet 41, the rod-shaped water pump is in air-blowing mode, and the water outlet 42 is closed. Figure 2 , 3 As shown in the diagram; when the rotating shaft 6 is rotated clockwise, and the second through hole 62 is directly opposite the water inlet 41 and the third through hole 63 is directly opposite the water outlet 42, the rod-shaped water pump is in the water pumping mode, and the air inlet 43 is in a closed state; a first touch switch 8 and a second touch switch 9 are fixedly installed on the mounting base 1, and a touch protrusion 64 is integrally installed on the rotating shaft 6. A limit groove 44 is provided on the circumferential surface of the shaft seat 4, and the touch protrusion 64 extends out of the limit groove 44. When the rod-shaped water pump is in the air blowing mode, the touch protrusion... 64 is in contact with the first touch switch 8; when the rod-shaped water pump is in the pumping mode, the touch protrusion 64 is in contact with the second touch switch 9, and the rotation angle of the touch protrusion 64 can be limited by the limiting groove 44, which also makes the switching of the rod-shaped water pump usage mode accurate.
