Pipe-free pump

Abstract

The invention discloses a pipe-free pump which comprises a pump body and a front cover connected to the pump body. A stator and a rotor are arranged in the pump body. An impeller is arranged on a rotating shaft of the rotor. The pump body comprises a shell integrally molded around the profile of the stator in an injection molding manner, a mounting portion molded at the front end of the shell in a secondary injection molding manner and used for being connected with the front cover and a containing cavity for containing the rotor. A water guide cover is arranged in the mounting portion. A water inlet located in the center and water outlets in the side edges of the water inlet are formed in the water guide cover. The impeller is arranged in a water cavity of the water guide cover. The pipe-free pump is simple and reasonable in structure and compact and firm in connection and has the beneficial effects of being low in vibration noise, stable in assembling quality and the like, and a great amount of manpower cost and a great amount of raw material cost are saved.

Description

technical field [0001] The present invention relates to a tubeless pump. Background technique [0002] A bathtub is a water storage device for bathing or showering, usually installed in a household bathroom. With the acceleration of the pace of life, people's work is more and more difficult and stressful, so after get off work, many people choose to soak in the bathtub for a long time to reduce or eliminate the fatigue on the body, so the jacuzzi should be used as needed pregnancy. The jacuzzi in the prior art uses a tubeless pump to spray water. The traditional tubeless pump is mostly a split assembly structure. The stator core of the motor and the coil winding are combined and then installed in the pump body and then poured into epoxy resin. It is sealed to prevent water from entering and burning out the motor components. This structure has many production processes and complicated processes, so the assembly time is long. The high cost of raw materials such as epoxy resin...

Problems solved by technology

The jacuzzi in the prior art uses a tubeless pump to spray water. The traditional tubeless pump is mostly a split assembly structure. The stator core of the motor and the coil winding are combined and then installed in the pump body and then poured into epoxy resin. It is sealed to prevent water from entering and burning out the motor components. This structure has many production processes and complicated processes, so the assembly time is long. The high cost of raw materials such as epoxy resin leads to high production costs, and the motor cannot be disassembled and repaired when there is a problem. , causing the entire ductless pump to be wasted

In addition, the existing jacuzzi water jets are usually set at the center of the front cover of the tubeless pump and spray water from a single port. This structure has a single water jet and the massage effect is not ideal.
