Description

Water pump with improved pump body structure Technical Field The utility model belongs to the technical field of water pumps, and relates to a water pump with an improved pump body structure. Background The pump body of the water pump not only provides physical support and installation space for internal components, but also ensures high-efficiency flow of fluid through reasonable flow channel design, bears operating pressure and assists in heat dissipation, and is a key component for ensuring normal operation of the water pump. The chinese patent with the patent publication number CN209604270U discloses a pump body of a water pump, an impeller cavity is arranged inside, a liquid inlet and a liquid outlet are arranged on the pump body, the liquid inlet, the liquid outlet and the impeller cavity are arranged in a triangle, the liquid inlet and the liquid outlet are positioned on the same side of the impeller cavity, a liquid inlet cavity and a liquid outlet cavity which are communicated with the impeller cavity are also arranged in the pump body, the liquid inlet cavity is positioned between the liquid inlet and the impeller cavity, the liquid outlet cavity is positioned between the liquid outlet and the impeller cavity, a liquid outlet is arranged at the position of the impeller cavity, the number of liquid outlets is two, the liquid outlet comprises a horizontal liquid outlet and a vertical liquid outlet, and the axes of the horizontal liquid outlet and the vertical liquid outlet are perpendicular. In the pump body of the water pump, the liquid inlet, the liquid outlet and the impeller cavity are arranged at the triangular positions, so that the purpose of compactness is achieved, but the structure shortens the distance of the flow channel inside the pump body, and the flow channel is difficult to be arranged into a smooth structure, so that the working efficiency of the water pump is influenced. Disclosure of utility model The utility model aims to solve the problems in the prior art and provide a water pump with an improved pump body structure. The water pump with the improved pump body structure comprises a water pump cover, a water pump body and a water pump motor, wherein the water pump cover is fixedly connected to one side of the water pump body, a water inlet hole and a water outlet hole are respectively formed in the upper end of the water pump body, a water inlet flow passage, a water outlet flow passage, a volute cavity and a water storage cavity are formed in the water pump body, the water inlet flow passage, the water outlet flow passage, the volute cavity and the water storage cavity are mutually communicated, the water inlet flow passage is communicated with the water inlet hole, the water storage cavity is communicated with the water outlet hole, the volute cavity is located between the water inlet flow passage and the water outlet flow passage, the tail end part of the water outlet flow passage is of a fan-shaped structure, a partition plate is arranged in the center of the tail end part of the water outlet flow passage, the water pump body is fixedly connected with one end of the water pump motor, a driving shaft extends out of the water pump motor, the driving shaft extends into the water pump body, and a water pump impeller is sleeved on the driving shaft and is located in the volute cavity. In the water pump with the improved pump body structure, one end of the pump body of the water pump is provided with a plurality of connecting columns, one end of the motor of the water pump is provided with a plurality of mounting columns, and long bolts are fixed in the connecting columns and the mounting columns. In the water pump with an improved pump body structure, a diversion inclined plane is arranged in the water inlet flow channel. In the water pump with the improved pump body structure, the water inlet joint and the water outlet joint are respectively and fixedly arranged outside the water inlet hole and the water outlet hole. Compared with the prior art, the water pump with the improved pump body structure has the advantages that 1, through the arrangement of the flow guiding inclined plane in the water inlet flow channel, the conveying efficiency of fluid in the water inlet flow channel is improved, 2, through the arrangement of the tail end part of the water outlet flow channel in a fan-shaped structure and the arrangement of the baffle plate at the tail end part of the water outlet flow channel, the water pump with the improved pump body structure plays a role of a check valve, fluid is prevented from flowing back when the water pump is stopped, and through the backflow prevention, the baffle plate can ensure that the backflow resistance is not needed to be overcome when the water pump is started, so that the starting efficiency and the overall operation efficiency of the water pump are improved.
