Description

Technical Field

[0001] The utility model belongs to the technical field of water pump structures, in particular to a water pump. Background Art

[0002] Water pumps are widely used, especially in the cleaning industry, where water pumps are needed to pump liquid to a designated location. For users, a cleaning gun is often used to clean vehicles. Conventional cleaning guns have built-in water pumps. Users put the water pipe into the water or river, start the cleaning gun, and the cleaning gun pumps liquid for cleaning. Common cleaning guns have built-in water pumps and hanging batteries, so the overall weight of the cleaning gun is large and it is difficult to use.

[0003] Therefore, cleaning guns with external water pumps have appeared on the market. The water pump is not set on the gun body, but at the end of the water pipe, and the water pump is directly placed in the water or river, which can effectively reduce the weight of the cleaning gun. However, this solution also has shortcomings: the overall weight of the water pump is large, and the water pump sinks to the bottom during daily use; if used in an outdoor river, the water inlet of the sinking water pump may be blocked by water plants at the bottom of the riverbed, and the water pump may be stuck at the bottom of the riverbed and cannot be dragged or is difficult to drag. Summary of the invention

[0004] The utility model aims to provide a water pump which can float on the water surface.

[0005] The purpose of the utility model is achieved in this way:

[0006] A water pump comprises a main body, wherein a pump body is arranged inside the main body; a floating body is arranged at the upper end of the main body, and the whole water pump can float on the water surface by relying on the floating body;

[0007] The pump body includes a motor and an impeller. A liquid pumping seat is arranged at the lower end of the main body. The liquid pumping seat has a water inlet and a drain outlet. The motor drives the impeller to rotate in the liquid pumping seat. The liquid enters the liquid pumping seat from the water inlet and is discharged from the drain outlet. The pump body is located at the lower end of the floating main body. When the water pump is put into the water, the pump body naturally hangs into the water under the action of gravity, and the water pump floats on the water surface relying on the floating main body.

[0008] The floating body has a chamber in which a battery is placed, and the battery supplies power to the pump body;

[0009] The floating body comprises a lower body and an upper cover, the upper cover and the lower body are fixed to each other, and a sealing ring is arranged at the connection position between the two; under the action of the sealing ring, the chamber of the floating body is in a closed state.

[0010] The lower body is fixed on the upper part of the main body or the lower body is integrally formed on the upper part of the main body, and the lower body is communicated with the main body.

[0011] The water inlet is located at the lower end of the liquid extraction seat, and the water outlet is located at the side of the liquid extraction seat.

[0012] An annular cavity is formed in the middle of the pumping seat, the impeller is located in the annular cavity, the water inlet is located at the lower part of the annular cavity; and the drain outlet is located at the side of the annular cavity.

[0013] The lower end of the annular cavity is provided with a water storage area with a diameter smaller than that of the impeller, and the impeller does not enter the water storage area; the water inlet is located in the water storage area.

[0014] The impeller comprises a lower impeller and an upper impeller fixed to each other, and a plurality of arc-shaped guide vanes are arranged on the upper impeller or the lower impeller.

[0015] A guide column is arranged in the middle of the upper impeller, and at least three arc-shaped guide vanes are arranged around the circumference of the guide column; the guide column is provided with an inclined wall.

[0016] The upper impeller is fixed on the output shaft of the motor; a sealing ring is arranged between the main body and the liquid pumping seat; under the action of the sealing ring, the chamber in the middle of the liquid pumping seat is in a closed state.

[0017] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0018] 1. The utility model adopts a water pump with a floating body. When the water pump is placed in water or a river, the water pump can float on the water surface. When the user drags it, the water pump can follow it more easily. The water pump in the floating state is not easily blocked by weeds or gravel at the bottom of the river, which is more convenient for users to use. In addition, the battery is sealed in the floating body, so that the center of gravity of the whole moves upward, which is conducive to the stability of the floating state. In addition, the chamber space of the floating body is large, which is more convenient for placing the battery.

[0019] 2. The pump body of the utility model is located below the floating body, so the center of gravity of the whole water pump is located below the floating body. Therefore, when the water pump is put into the water, the pump body naturally hangs into the water under the action of gravity, and the water pump floats on the water surface relying on the floating body. The user only needs to put the water pump into the water and start the pump body to pump liquid.

[0020] 3. The lower end of the annular cavity of the utility model is provided with a water storage area with a diameter smaller than that of the impeller, and the impeller does not enter the water storage area; the water inlet is located in the water storage area. By providing the water storage area, the liquid can have a buffer area, making the pumping process more continuous.

[0021] 4. The impeller of the utility model includes a lower impeller and an upper impeller fixed to each other, and a plurality of arc-shaped guide vanes are arranged on the upper impeller or the lower impeller. The impeller is formed by fixing two separate parts, which is conducive to the production and processing of the impeller and reduces the difficulty of mold production. Preferably, a guide column is arranged in the middle of the upper impeller, and at least three arc-shaped guide vanes are arranged around the circumference of the guide column; the guide column is provided with an inclined wall, and the water flow is drained by the guide column with an inclined wall, which is conducive to pumping liquid.

[0033] A water pump includes a main body 1, in which a pump body is arranged; a floating main body 3 is arranged at the upper end of the main body 1, and the whole water pump can float on the water surface by relying on the floating main body 3. The floating main body 3 has a chamber, and a battery 8 is placed in the chamber. The battery 8 supplies power to the pump body. The present application preferably places the battery in the water pump, and of course, the water pump can also be remotely powered by wires; the floating main body 3 includes a lower main body 31 and an upper cover 32, the upper cover 32 and the lower main body 31 are fixed, and a sealing ring 19 is arranged at the connection position between the two; under the action of the sealing ring 19, the chamber of the floating main body is in a closed state. By packaging the battery 8 inside, the battery 8 can be stably installed in the floating main body 3. The whole water pump can float on the water surface by using the floating main body 3, and the applicable scenes are wider. The user only needs to configure a light spray gun and connect the water pump to work. The spray gun has no pump body and battery, and the weight of the spray gun is greatly reduced. The pump body includes a motor 4 and an impeller 5. A pumping seat 2 is provided at the lower end of the main body 1. The pumping seat 2 has a water inlet 21 and a water outlet 22.
