[0004] To achieve the above purpose, the present utility model provides the following technical solution: a brushless motor for a piston high-pressure water pump, comprising: a front housing; a rear housing, wherein the front housing and the rear housing together form a housing body of an engine; a stator iron core, wherein the stator iron core is fixedly installed inside the housing body, with a coil wound and fixed on the stator iron core; a rotor iron core, wherein the rotor iron core is provided inside the housing body and fits relative to the stator iron core, wherein four magnets are installed inside the rotor iron core, wherein the rotor iron core is provided on both sides in one direction of a shaft with a compensating block, wherein the compensating block is firmly connected to the rotor iron core; a shaft, wherein the shaft passes through the center of the rotor iron core and is firmly connected to the rotor iron core; an insulating adhesive, wherein the insulating adhesive is provided in a wear-prone part within the motor; and a cooling fan, wherein the cooling fan is mounted on the housing of the motor; wherein the brushless motor works together and is connected to a piston high-pressure water pump of a household cleaner to provide a driving force for the piston high-pressure water pump.

[0005] Preferably, the four magnets are all embedded inside the rotor iron core and distributed along a circumferential direction of the rotor iron core, and corresponding to the coil on the stator iron core, in order to interact with an electromagnetic field.

[0006] Furthermore, the compensating block is attached and fastened to end faces on the sides of the rotor iron core facing the front housing and the rear housing, and is designed to be coaxial with the rotor iron core and the shaft in order to be adapted to a rotational movement of the rotor iron core.

[0007] Furthermore, the coil is tightly wound on an outer side wall of the stator iron core, with one terminal end of the coil extending to the outside of the housing body to be connected to an external power supply line.

[0008] Furthermore, the two ends of the shaft extend in the direction of the shaft towards the outside of the rotor iron core and are positioned opposite an inside of the front housing and the rear housing, and rotate synchronously with the rotation of the rotor iron core.

[0009] Based on the solutions above, the insulating adhesive is applied to the surface of wear-prone parts inside the engine and coated on the wear-prone parts to provide double protection against wear and for insulation.

[0010] Based on the above solutions, the cooling fan is also mounted on an end section of the housing body and works in conjunction with a rotary structure of the motor, operating synchronously with the motor operation to dissipate the heat inside the housing body.

[0013] The electromagnetic field interacts with the magnets to achieve rotary drive. The rotor core's balancing blocks ensure stability during rotation and reduce vibrations and noise during operation. The insulating adhesive not only effectively prevents wear on the parts but also further reduces the likelihood of failure. The cooling fan dissipates heat synchronously and maintains the operating temperature. The rigid connection between the shaft and the rotor core ensures a reliable transmission of drive power, delivering stable performance suitable for the actual working demands of household cleaners.

[0016] With reference to Fig.The brushless motor for a piston high-pressure water pump comprises a front housing 1, to which a rear housing 2 is fitted, with the front housing 1 and the rear housing 2 together forming a housing body of the motor. A stator iron core 3 is fixedly installed inside the housing body, with a coil 4 wound and attached to the stator iron core 3. A rotor iron core 5 is provided inside the housing body and fits relative to the stator iron core 3. Four magnets 6 are installed inside the rotor iron core 5. The rotor iron core 5 is provided on both sides in one direction with a counterweight 7, the counterweight 7 being fixedly connected to the rotor iron core 5. A shaft 8 passes through the center of the rotor iron core 5 and is fixedly connected to the rotor iron core 5.An insulating adhesive 9 is provided in a wear-prone area within the motor. A cooling fan 10 is mounted on the motor housing. The brushless motor is connected to the household cleaner's piston high-pressure water pump to provide the driving force for the piston high-pressure water pump. The function of the front housing 1 is to form a housing body with the rear housing to protect the internal components inside the motor on one side, and the function of the rear housing 2 is to form a closed housing body with the front housing 1 to protect the internal core components inside the motor. The function of the housing body is to provide a mounting base and external protection for all internal components, such as the stator iron core 3, the rotor iron core 5, etc., to prevent foreign objects from entering the interior of the motor and impairing its operation.The function of the stator iron core 3 is to provide a support for the winding and a mounting for the coil 4 to ensure the coil 4's rigidity. The function of the coil 4, after excitation, is to generate an electromagnetic field to provide a power source for motor operation. The function of the rotor iron core 5 is to interact with the stator iron core 3 to achieve rotation through interaction with the electromagnetic field. The function of the magnets 6 is to interact with the electromagnetic field of the coil 4 to generate a force that sets the rotor iron core 5 in rotation. The function of the balancing blocks 7 is to ensure the stability of the rotor iron core 5's rotation.The function of shaft 8 is to transmit the rotational driving force of the rotor iron core 5 to drive the piston high-pressure water pump, and the function of the insulating adhesive 9 is to protect the wear-prone parts inside the motor. The function of the cooling fan 10 is to dissipate heat from inside the motor to ensure that the motor operates at an appropriate temperature. Operating principle:

[0017] When the brushless motor is used for a piston high-pressure water pump, the connection should first be made as follows: Carefully connect the brushless motor to the piston high-pressure water pump, ensure that the shaft 8 is firmly connected to the piston high-pressure water pump, ensure that the magnet 6, the balancing block 7, the cooling fan 10 and other components do not loosen and that the housing seal is good, then the installation preparation is complete.

[0018] Next, the motor is energized to achieve rotation, specifically as follows: one terminal of coil 4 on the stator core 3 is connected to the external power supply line. Coil 4 is energized to generate an electromagnetic field, which interacts with the four magnets 6 embedded in the rotor core 5. The rotor core 5 rotates around its central shaft 8 to achieve motor rotation. Simultaneously, the rotor core 5 rotates with the counterweights 7 on either side of the shaft 8, synchronously with the rotation of the rotor core 5. This counterweights compensate for the eccentric force generated by the rotation of the rotor core 5, thereby reducing motor vibrations and noise, and ensuring stable motor rotation.

[0019] To ensure heat dissipation from the motor and power transmission, the specific operation is as follows: The rotor iron core 5 rotates, driving the motor's rotation. The cooling fan 10 operates synchronously with the motor, drawing cool air into the housing and dissipating heat. The insulating adhesive 9 inside the motor protects wear-prone parts and reduces frictional loss. The rotational force from the rotor iron core 5 is transmitted to the shaft 8, which rotates synchronously with the rotor iron core 5. This rotational force is then transferred to the piston high-pressure water pump, which powers the high-speed operation and provides stable and efficient drive power for the cleaning operation of household cleaners. To stop operation, disconnect the connection between the coil 4 and the external power supply line.The electromagnetic field of coil 4 disappears, the rotor iron core 5 stops rotating, the shaft 8 and the cooling fan 10 also stop running, and the power supply to the piston high-pressure water pump is interrupted, and the work is stopped.
