Description

Technical Field

[0001] This utility model relates to water pumps, and more particularly to a rod-shaped water pump. 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. It 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. Sewage, oil, and other liquids pumped by the pump pass through the connecting pipe and are discharged through the outlet. However, to reduce labor, users often lean the rod-type water pump against the side of the water tank or other pumping area, allowing it to pump automatically. This results in the pump being tilted at the lower end of the connecting pipe. When the water in the tank or other area is pumped to the bottom, the tilted pump cannot completely remove the water from the bottom unless the user straightens the rod-type water pump so that it is flush with the bottom of the tank or other area. This causes some inconvenience in using the rod-type water pump. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a rod-shaped water pump that can automatically pump water out of pools and other places without user intervention, bringing convenience to users.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rod-shaped water pump, including a connecting pipe and a pump assembly located at the lower end of the connecting pipe, a connecting frame is sealed and fixed at the lower end of the connecting pipe, the pump assembly is hinged to the connecting frame, a channel is provided in the connecting frame, and the channel is connected to the connecting pipe and the pump assembly respectively.

[0005] Furthermore, the pump assembly includes a motor mounting base, a motor, a volute, and a filter cover. The motor mounting base is sealed and hinged to the connecting frame, and the lower end of the motor mounting base is open. The motor is fixed inside the motor mounting base, and an impeller is fixedly mounted on the drive shaft of the motor. The filter cover and the volute are both fixed to the lower end of the motor mounting base. The volute is located inside the motor mounting base and has a through hole. The impeller is located above the through hole, and the motor mounting base has a liquid passage hole that communicates with the channel.

[0006] Furthermore, the connecting wire between the wire connection point at the lower end of the connecting pipe and the wire connection point on the motor passes through the channel.

[0007] Furthermore, an installation ring is fixedly provided at the upper end of the connecting pipe, and at least two telescopic rods are hinged to the installation ring.

[0008] Compared with the prior art, the advantages of this utility model are that the lower end of the connecting pipe is fixed with a connecting frame, and the pump assembly is hinged to the connecting frame, so that the pump assembly can rotate. When in use, even if the rod-shaped water pump is leaned against a water tank or other place, the bottom surface of the pump assembly can still fit against the bottom of the water tank or other place, so that the rod-shaped water pump can automatically pump the water tank or other place clean without the user's manual support, which is convenient to use. In addition, since the connecting pipe is equipped with a telescopic rod, the telescopic rod can be pulled out as a support leg as needed, so that the rod-shaped water pump is in an upright position. When not in use, the telescopic rod can be retracted and used as a handle. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-3 As shown, a rod-shaped water pump includes a connecting pipe 1 and a pump assembly 2 located at the lower end of the connecting pipe 1. A connecting frame 3 is fixedly installed at the lower end of the connecting pipe 1. The pump assembly 2 includes a motor mounting base 21, a motor 22, a volute 23, and a filter cover 24. The motor mounting base 21 is sealed and hinged to the connecting frame 3, and the lower end of the motor mounting base 21 is open. The motor 22 is fixed inside the motor mounting base 21. An impeller 25 is fixedly installed on the drive shaft of the motor 22. The filter cover 24 and the volute 23 are both fixed at the lower end of the motor mounting base 21. The volute 23 is located inside the motor mounting base 21 and has a through hole 26. The impeller 25 is located above the through hole 26. The motor mounting base 21 has a liquid passage hole 27. A channel 31 is provided inside the connecting frame 3. The channel 31 is connected to the connecting pipe 1 and the liquid passage hole 27 respectively. A connecting wire 4 between the wire connection point at the lower end of the connecting pipe 1 and the wire connection point on the motor 22 passes through the channel 31.

[0016] In the above embodiment, the wire connection point at the lower end of the connecting pipe 1 and the wire connection point on the motor 22 are the existing wire connection points in the rod-shaped water pump.

[0017] In addition, to facilitate the upright operation of the rod-shaped water pump, a mounting ring 5 can be fixedly installed at the upper end of the connecting pipe 1. At least two telescopic rods 6 are hinged to the mounting ring 5. By pulling down the telescopic rods 6 to form support legs, the rod-shaped water pump can be kept in an upright position, preventing it from tipping over. Figure 4 As shown; when the rod-shaped water pump is not in use, the telescopic rod 6 can be retracted upwards, and the retracted telescopic rod 6 can also be used as a handle, as shown. Figure 5 As shown.

[0018] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
