Description

Technical Field

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

[0002] With the growth of the economy and the improvement of the scientific and technological level, individuals have more and better pursuits for the quality of life. More and more families at home and abroad have the conditions for private swimming pools. Different from public swimming pools, private swimming pools have higher requirements in all aspects. As the core of the swimming pool circulation system, a water pump with stronger performance and lower noise is their pursuit goal.

[0003] The silent water pump enables them not to be affected by the noisy motor sound when enjoying the fun of swimming, and not to be disturbed during night rest. The intelligent variable frequency control of the water pump can also reduce energy waste and noise pollution.

[0004] Traditional silent water pumps mainly consist of a filtering component, a pump body, a motor, etc. The motor, as the main power source, makes the impeller in the pump body rotate, sucks in the water before filtration, and after being filtered by the filtering component, the water flow will be thrown outwards under the action of the centrifugal force of the impeller. However, due to the absence of a blocking part, the water flow will flow back and generate noise. Summary of the Invention

[0005] The purpose of the utility model is to provide a silent water pump to solve the problems put forward in the above background art.

[0006] To solve the above technical problems, the utility model is realized by the following technical measures: A silent water pump includes a motor assembly that provides a power source. The front end of the motor assembly is connected to a pump body. The front of the pump body is connected to a filtering housing. A filtering component is arranged in the inner cavity of the filtering housing. An outlet is arranged on the filtering housing. Among them, a pump body base is arranged in the pump body. A semi-circular water outlet is arranged on the pump body base. A flow guide sleeve is installed on the pump body base. An inlet is arranged on the flow guide sleeve. A baffle is arranged on the flow guide sleeve. A semi-circular water outlet is arranged on the flow guide sleeve. A water outlet flow guide groove is arranged on the flow guide sleeve. A drain hole is arranged on the flow guide sleeve. A sealing ring is arranged on the flow guide sleeve.

[0007] Compared with the prior art, the advantages of the present utility model are as follows: By adding a baffle, a water outlet diversion groove, a drain hole, and a sealing ring to the traditional diversion sleeve, the water flow will not flow back due to the diversion effect of the baffle, reducing the generation of noise. The water outlet diversion groove (drain notch) is added to the diversion sleeve and the diversion sleeve base to guide the flow trajectory of the water and reduce noise. The drain hole of the diversion sleeve is added to prevent the water flow from forming a part of static stagnant water inside the diversion sleeve, generating unnecessary noise. In the connection area between the diversion sleeve and the external water outlet, the sealing ring is used to reduce the noise generated by the gap between the diversion sleeve and the external water outlet.

[0008] As an improvement of the present utility model, the pump body base and the diversion sleeve are two half-cavities, which form a total cavity after being enclosed and installed. The purpose of selecting this design is to facilitate the disassembly and assembly of the diversion sleeve. If the pump body base and the diversion sleeve are designed as one part, due to the relatively many internal technical features, the production and manufacturing are more troublesome.

[0009] As an improvement of the present utility model, there are two water outlet diversion grooves, which are symmetrically arranged. The purpose of selecting this design is that the symmetrically arranged structure can make the water flow velocity uniform and stable when discharging water.

[0010] As an improvement of the present utility model, the position of the drain hole is set at the bottom of the diversion sleeve. The purpose of selecting this design is to prevent the water flow from forming a part of static stagnant water inside the diversion sleeve, generating unnecessary noise. Description of the Drawings
