Technical Field

[0001] The utility model relates to the technical field of circulating water pumps, and particularly relates to an efficient circulating water pump device. Background Art

[0002] As the core component of the water circulation system, the circulating water pump is widely used in various occasions where water flow circulation is required. For example, the flowing water features or fish tanks in families need to use circulating water pumps.

[0003] Traditional circulating water pumps usually adopt a centrifugal design, and the impeller is driven by a motor to rotate at a high speed to pump water. When the motor drives the impeller to rotate at a high speed, it is easy to generate noise. Moreover, it needs to work continuously for a long time in a family water feature or fish tank, causing noise pollution indoors. In addition, when the water flow is sucked into the circulating water tank, the falling water flow will also generate noise, further aggravating the indoor noise.

[0004] Therefore, it is necessary to invent an efficient circulating water pump device to solve the above problems. Content of the Utility Model

[0007] By adopting the above technical solution, the motor body drives the impeller to rotate to suck the water inside the return water tank body. At this time, the sound insulation cotton on the side walls of the protective cover and the return water tank body reduces the sound generated by the motor driving the impeller to rotate, reducing the transmission of noise. At the same time, the return water flows into the interior of the guide pipe and then flows into the interior of the return water tank body through a plurality of groups of water inlet holes, slowing down the water flow rate and reducing the noise of the water flow, thereby effectively reducing the noise during the use of the circulating pump.

[0010] Optionally, a drain pipe is fixedly connected to the upper side of the left surface of the return water tank body. The right end of the drain pipe is fixedly connected to a suction pipe. The lower end of the suction pipe is fixedly connected to a suction head. A filter screen is fixedly connected to the side water inlet of the suction head.

[0011] By adopting the above technical solution, the suction pipe and the drain pipe cooperate to suck the water flow inside the return water tank body, and at the same time, the filter screen filters the impurities in the return water.

[0012] Optionally, heat dissipation holes are opened at the upper end of the protective cover, and a protective net is arranged above the heat dissipation holes.

[0014] Optionally, two groups of first connecting plates are fixedly connected to the upper surface of the fixed cover plate, and threaded holes are formed on the surfaces of the first connecting plates.

[0015] Optionally, second connecting plates are fixedly connected to the lower ends of the front and rear surfaces of the protective cover, and through holes are formed on the surfaces of the second connecting plates.

[0016] By adopting the above technical solution, screws are passed through the through holes and threadedly connected to the threaded holes to fix the first connecting plate and the second connecting plate, thereby fixing the protective cover.

[0017] Optionally, a liquid supplement hole is opened on the right side of the fixed cover plate. A sealing cover is hinged to the side wall of the liquid supplement hole, and a handle is fixedly connected to the upper surface of the sealing cover.

[0018] By adopting the above technical solution, the liquid supplement hole is used to supplement the interior of the return water tank body with liquid.

[0019] Optionally, a plurality of support blocks are fixedly connected to the right inner wall of the liquid supplement hole, and a locking plate is rotatably connected to the surface of the fixed cover plate at a position on the right side of the liquid supplement hole.

[0020] By adopting the above technical solution, the support plates support the lower end of the sealing cover, and the locking plate is rotated to the upper side of the sealing cover to lock and fix the sealing plate.

[0021] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0022] 1. The utility model drives the impeller to rotate through the motor body to suck the water inside the return water tank body. At this time, the sound insulation cotton on the side wall of the protective cover and the return water tank body reduces the sound generated by the motor driving the impeller to rotate, reducing the transmission of noise. At the same time, the return water flows into the inside of the diversion pipe and flows into the inside of the return water tank body through multiple water inlet holes, slowing down the water flow velocity and reducing the noise of the water flow. Furthermore, the noise during the use of the circulation pump is effectively reduced, solving the problem that the motor driving the impeller is prone to generate noise during high-speed operation, and needs to work continuously for a long time in a household water feature or fish tank, causing noise pollution to the indoor environment. Moreover, during the process of sucking the water flow into the circulation water tank, the falling water flow will also generate noise, further exacerbating the indoor noise problem;

[0023] 2. The utility model collects the water body to the middle of the return water tank body through the inclined diversion plate, and the suction head is at the lowest end of the diversion plate, so that the suction pipeline always maintains the best suction state, thereby realizing efficient circulation.
