Description

Technical Field

[0001] This utility model belongs to the field of motor equipment technology, specifically relating to a plastic-encapsulated motor for ventilation fans. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a energized coil, which acts on the rotor to create magnetoelectric torque. An electric motor mainly consists of a stator and a rotor. The direction of the force exerted on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] Plastic-encapsulated motors utilize plastic encapsulation technology to completely encapsulate the motor's stator core, windings, and other components with engineering plastics, eliminating the need for traditional stator insulation processes and the metal casing of ordinary motors. These micro-motors are used in household appliances such as vacuum cleaners, range hoods, air conditioners, and washing machines, as well as in instrument fans. The research and production of plastic-encapsulated motors are receiving increasing attention both domestically and internationally, and their promising future is attributed to a series of advantages not found in metal-cased motors.

[0004] The housing of the encapsulated motor is integrally encapsulated. The encapsulated motor used in the ventilation fan is fixed to the back of the ventilation fan by a mounting bracket. During use, the ventilation fan will generate vibration. In the existing technology, the stability of the ventilation fan motor is not high. Long-term use can easily affect the stability of the ventilation fan, and the motor of the ventilation fan needs to be maintained frequently. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a plastic-encapsulated motor for ventilation fans. By installing a fixing component on the outside of the housing, with one end of the fixing component connected to the mounting bracket and the other end of the mounting bracket connected to the ventilation fan, the stability of the plastic-encapsulated motor body installation is increased, the stability of the ventilation fan operation is guaranteed, and the maintenance frequency is reduced.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A molded motor for an exhaust fan includes: a molded motor body, which comprises a housing, an output shaft, and a fixing assembly. The output shaft is rotatably connected within the housing and is connected to the fan blades of the exhaust fan, driving the blades to rotate. The fixing assembly is fixedly connected to the outside of the housing, and the fixing assembly secures the molded motor body to the exhaust fan via a mounting bracket. This invention increases the stability of the molded motor body installation by installing the fixing assembly on the outside of the housing, with one end of the fixing assembly connected to the mounting bracket and the other end of the mounting bracket connected to the exhaust fan. This ensures the stability of the exhaust fan operation and reduces maintenance frequency.

[0008] Furthermore, the fixing assembly includes two semi-circular clips and limiting members. The two semi-circular clips are clamped and fixed to the outside of the housing, and the limiting members are respectively provided on the front and rear sides of the semi-circular clips, limiting and fixing the semi-circular clips to the housing. The semi-circular clips are designed to clamp and fix to the outside of the housing, and the limiting members increase the connection strength between the semi-circular clips and the housing, thereby limiting the semi-circular clips to the housing.

[0009] Furthermore, the semi-circular clamp includes a clamp body, connecting ends, and connecting screws. The connecting ends are located at both ends of the clamp body. When the two semi-circular clamps are fixed, the corresponding two connecting ends abut against each other. The connecting screw passes through the corresponding two connecting ends, and limit nuts are screwed into both ends of the connecting screw, which are tightened onto the connecting ends. When the two semi-circular clamps are fixedly clamped to the outside of the housing, the fixed connection between the semi-circular clamps and the housing is achieved by passing the connecting screw through the connecting ends and screwing limit nuts into both ends of the connecting screw.

[0010] Furthermore, the housing has an annular groove corresponding to the semi-circular clip, and the semi-circular clip is clamped in the annular groove. The annular groove can limit the semi-circular clip and restrict its fixed position, thereby increasing the stability of the connection between the semi-circular clip and the housing.

[0011] Furthermore, the limiting component includes a telescopic connecting rod, a spring, and a limiting end. The semi-circular clamp has mounting holes on both its front and rear sides, and corresponding limiting grooves are provided on both the front and rear arms of the annular groove. One end of the telescopic connecting rod is fixedly connected to the mounting hole, and the other end is fixedly connected to the limiting end. The spring is sleeved on the outside of the telescopic connecting rod, with one end connected to the mounting hole and the other end connected to the limiting end. The limiting end matches the limiting groove. When the semi-circular clamp is clamped in the annular groove, the spring controls the telescopic connecting rod to insert the limiting end into the limiting groove. First, the limiting end is pressed into the mounting hole. Then, after the semi-circular clamp is placed into the annular groove, the limiting end located in the mounting hole, controlled by the spring, causes the telescopic connecting rod to drive the limiting end into the limiting groove, thereby limiting the semi-circular clamp within the annular groove and improving the stability of the connection between the semi-circular clamp and the housing.

[0012] Furthermore, a threaded column one is fixedly connected to one side of the semi-circular clamp, and a corresponding threaded column two is fixedly connected to the back of the exhaust fan. One end of the mounting bracket passes through threaded column one, and a locking nut one is screwed into threaded column one, tightening the locking nut one at one end of the mounting bracket. The other end of the mounting bracket passes through threaded column two, and a locking nut two is screwed into threaded column two, tightening the locking nut two at the other end of the mounting bracket. The arrangement of threaded columns one and two facilitates the fixed connection of the mounting bracket.

[0013] Furthermore, the inner wall of the semi-circular clamp is equipped with shock-absorbing pads. The shock-absorbing pads are designed to reduce vibrations transmitted from the motor to the mounting components.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] This invention increases the stability of the encapsulated motor body installation by installing a fixing component on the outside of the housing. One end of the fixing component is connected to the mounting bracket, and the other end of the mounting bracket is connected to the ventilation fan. This ensures the stability of the ventilation fan operation and reduces the maintenance frequency.

[0016] This utility model discloses a semi-circular clip comprising a clip body, connecting ends, and connecting screws. The connecting ends are located at both ends of the clip body. When two semi-circular clips are fixed, the corresponding two connecting ends abut against each other. The connecting screw passes through the corresponding two connecting ends, and limit nuts are screwed into both ends of the connecting screw, tightening them onto the connecting ends. When the two semi-circular clips are fixedly clamped to the outside of the housing, the connection between the semi-circular clips and the housing is achieved by passing the connecting screw through the connecting ends and screwing limit nuts into both ends of the connecting screw. The housing has an annular groove corresponding to the semi-circular clips, and the semi-circular clips are clamped within the annular groove. The annular groove provides a limiting function for the semi-circular clips, restricting their fixed position and increasing the stability of the connection between the semi-circular clips and the housing.

[0017] The limiting component in this invention includes a telescopic connecting rod, a spring, and a limiting end. The semi-circular clamp has mounting holes on both its front and rear sides, and corresponding limiting grooves on both the front and rear arms of the annular groove. One end of the telescopic connecting rod is fixedly connected to the mounting hole, and the other end is fixedly connected to the limiting end. The spring is sleeved on the outside of the telescopic connecting rod, with one end connected to the mounting hole and the other end connected to the limiting end. The limiting end matches the limiting groove. When the semi-circular clamp is clamped in the annular groove, the spring controls the telescopic connecting rod to insert the limiting end into the limiting groove. First, the limiting end is pressed into the mounting hole. Then, after the semi-circular clamp is placed into the annular groove, the limiting end in the mounting hole, controlled by the spring, causes the telescopic connecting rod to drive the limiting end into the limiting groove, thereby limiting the semi-circular clamp within the annular groove and improving the stability of the connection between the semi-circular clamp and the housing.

Detailed Implementation

[0025] like Figures 1 to 5 As shown, the encapsulated motor for the ventilation fan of this utility model includes: an encapsulated motor body 1, the encapsulated motor body 1 including a housing 2, an output shaft 3 and a fixing component 4, the output shaft 3 being rotatably connected inside the housing 2, the output shaft 3 being connected to the fan blades 5 of the ventilation fan and driving the fan blades 5 to rotate, the fixing component 4 being fixedly connected to the outside of the housing 2, and the fixing component 4 fixing the encapsulated motor body 1 to the ventilation fan through a mounting bracket 6.

[0026] The fixing component 4 includes two semi-circular clips 7 and limiting members 8. The two semi-circular clips 7 are clamped and fixed to the outside of the housing 2. The limiting members 8 are respectively provided on the front and rear sides of the semi-circular clips 7, and the limiting members 8 limit and fix the semi-circular clips 7 to the housing 2. The semi-circular clips 7 are provided to clamp and fix to the outside of the housing 2, and the limiting members 8 increase the connection strength between the semi-circular clips 7 and the housing 2, thereby limiting the semi-circular clips 7 to the housing 2.

[0027] The semi-circular clip 7 includes a clip body 9, a connecting end 10, and a connecting screw 11. The connecting end 10 has two ends of the clip body 9. When the two semi-circular clips 7 are fixed, the corresponding two connecting ends 10 abut against each other, and the connecting screw 11 passes through the corresponding two connecting ends 10. Both ends of the connecting screw 11 are screwed with limit nuts 23, which are tightened onto the connecting end 10. When the two semi-circular clips 7 are fixedly clamped to the outside of the housing 2, the fixed connection between the semi-circular clips 7 and the housing 2 is achieved by passing the connecting screw 11 through the connecting end 10 and screwing the limit nuts 23 into both ends of the connecting screw 11.

[0028] The housing 2 has an annular groove 12 corresponding to the semi-circular clip 7, and the semi-circular clip 7 is clamped in the annular groove 12. The annular groove 12 can limit the semi-circular clip 7, limit the fixed position of the semi-circular clip 7, and increase the stability of the connection between the semi-circular clip 7 and the housing 2.

[0029] The limiting component 8 includes a telescopic connecting rod 13, a spring 14, and a limiting end 15. The semi-circular clamp 7 has mounting holes 16 on both the front and rear sides. The annular groove 12 has corresponding limiting grooves 17 on both the front and rear sides. One end of the telescopic connecting rod 13 is fixedly connected to the mounting hole 16, and the other end of the telescopic connecting rod 13 is fixedly connected to the limiting end 15. The spring 14 is sleeved on the outside of the telescopic connecting rod 13. One end of the spring 14 is connected to the mounting hole 16, and the other end of the spring 14 is connected to the limiting end 15. The limiting end 15 is matched with the limiting groove 17. When the semi-circular clamp 7 is clamped in the annular groove 12, the spring 14 controls the telescopic connecting rod 13 to insert the limiting end 15 into the limiting groove 17. First, the limiting end 15 is pressed into the mounting hole 16. Then, the semi-circular clip 7 is placed into the annular groove 12. The limiting end 15 in the mounting hole 16 is controlled by the spring 14, which causes the telescopic connecting rod 13 to drive the limiting end 15 into the limiting groove 17. This achieves the limiting of the semi-circular clip 7 in the annular groove 12, improving the stability of the connection between the semi-circular clip 7 and the housing 2.

One end of the mounting bracket 6 passes through the threaded column 18, and a locking nut 20 is screwed into the threaded column 18, tightening the locking nut 20 at one end of the mounting bracket 6. The other end of the mounting bracket 6 passes through the threaded column 29, and a locking nut 21 is screwed into the threaded column 29, tightening the locking nut 21 at the other end of the mounting bracket 6. The arrangement of the threaded columns 18 and 29 facilitates the fixed connection of the mounting bracket 6.

[0031] The inner wall of the semi-circular clip 7 is provided with a shock-absorbing pad 22. The shock-absorbing pad 22 is provided to reduce the vibration transmitted from the motor to the fixing component 4.

[0032] This invention increases the stability of the encapsulated motor body 1 during installation by installing a fixing component 4 on the outside of the housing 2. The fixing component 4 is connected to one end of the mounting bracket 6, and the other end of the mounting bracket 6 is connected to the ventilation fan. This ensures the stability of the ventilation fan operation and reduces the maintenance frequency.
