The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.

[0026] In the description of the utility model, the orientation description such as the orientation or positional relation indicated by up, down, front, back, left, right etc. based on the orientation or positional relation shown in the drawing is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the utility model.

[0027] It should be understood that when one element (for example, a first element) is "connected" to another element (for example, a second element), the element can be directly connected to the other element, or there can be an intervening element (for example, a third element) between the element and the other element.

[0028] The embodiment of the utility model provides a kind of mounting structure for plastic package motor of range hood, as shown in Figures 1-5 It includes:

[0029] Plastic package motor body 100, plastic package motor body 100 includes rotor 110 and stator 120, stator 120 is provided with opening, rotor 110 is arranged in stator 120 by the opening of stator 120, and the outer wall of stator 120 is equipped with fixed structure 130, fixed structure 130 is equipped with mounting hole 140, and the side wall of mounting hole 140 is equipped with open mouth;

[0030] End cover 200, end cover 200 is arranged at the opening of stator 120 and closes opening, to limit rotor 110 in stator 120;

[0031] Limit fastener 300, limit fastener 300 includes head 310, limiting portion 320 and fastening portion 330 for being connected with range hood cooperation, and fastening portion 330 is equipped with screw thread;

[0032] Cushion foot pad 400 is used to form elastic support to plastic package motor body 100, cushion foot pad 400 can be inserted into mounting hole 140 from open mouth, and cushion foot pad 400 is equipped with fixed hole 410 for limit fastener 300, and fixed hole 410 is matched with limiting portion 320.

[0033] The plastic-sealed motor body 100 includes a rotor 110 and a stator 120. The rotor 110 is arranged inside the stator 120 through an opening of the stator 120. The stator 120 is provided with a fixing structure 130 on its outer wall. The fixing structure 130 is provided with mounting holes 140. The side walls of the mounting holes 140 are provided with openings. An end cover 200 is arranged at the opening of the stator 120 and seals the opening. The purpose of this design is to limit the rotor 110 inside the stator 120. Through the cooperation of the end cover 200 and the stator 120, the sealing of the plastic-sealed motor body 100 can be achieved, preventing oil fume from entering. To further improve the sealing effect, sealing glue can also be applied between the end cover 200 and the stator 120. The limiting fastener 300 includes a head 310, a limiting portion 320, and a fastening portion 330. The fastening portion 330 is equipped with threads, which are specially designed for connection with the extractor hood. The extractor hood is provided with corresponding threaded holes, so that the fastening portion 330 can be smoothly inserted. The main function of the limiting portion 330 is to control the depth of the fastener inserted into the extractor hood. Since the fastening portion 330 has threads and the limiting portion 330 does not, when the limiting portion 330 contacts the threaded holes of the extractor hood, it cannot match the threaded holes due to its smooth surface without threads, thereby effectively limiting the insertion depth. The shock-absorbing foot pad 400 is a component used to provide elastic support to the plastic-sealed motor body 100. The shock-absorbing foot pad 400 can be inserted into the mounting hole 140 from the opening of the fixing structure 130. It is provided with a fixed hole 410 for the limiting fastener 300 to pass through. The fixed hole 410 cooperates with the limiting portion 320. Through the cooperation of the shock-absorbing foot pad 400 mounted on the limiting fastener 300 and the fixing structure 130, the plastic-sealed motor is accurately positioned and its stability is ensured. In addition, this design also provides additional shock-absorbing function to reduce the impact of vibration on the extractor hood, ensuring the smooth operation of the equipment.

[0034] In some embodiments, the upper end of the fixing structure 130 is provided with a limiting groove 150 for limiting the passage of the shock-absorbing foot pad 400.

[0035] The limiting groove 150 can limit the horizontal or vertical movement of the shock-absorbing foot pad 400 in the mounting hole 140, ensuring that the shock-absorbing foot pad 400 does not move excessively or fall off during use, thereby maintaining the stability of the motor. Through the design of the limiting groove 150, the position of the shock-absorbing foot pad 400 can be more accurately controlled.

[0036] Further, the shock-absorbing foot pad 400 includes a first shock-absorbing pad 420 cooperating with the limiting groove 150 and a limiting sleeve 430 cooperating with the mounting hole 140.

[0037] The first shock pad 420 cooperates with the limiting groove 150 at the upper end of the fixed structure 130, which can limit the movement of the first shock pad 420 in the vertical direction and ensure its correct position in the mounting hole 140. As a part of the shock absorbing foot pad 400, the main function of the first shock pad 420 is to absorb and reduce the vibration generated during the operation of the motor, reduce the impact on the structure of the range hood, and improve the overall stability and service life. The limiting sleeve 430 cooperates with the mounting hole 140 on the shock absorbing foot pad 400, and the limiting sleeve 430 can enter the mounting hole 140 by overcoming the elastic force. The main function of the limiting sleeve 430 is to limit the movement of the shock absorbing foot pad 400 in the mounting hole 140, so that the limiting fastener 300 can stably fix the motor and prevent displacement caused by vibration or external force. Through the cooperation of the first shock pad 420 and the limiting sleeve 430, the vibration and displacement of the motor can be more effectively controlled, and the stability of the entire range hood system can be improved.

[0038] Further, the shock absorbing foot pad 400 further comprises a second shock pad 440, which is in the shape of a cylinder, and the outer diameter of the second shock pad 440 is greater than the diameter of the fixed hole 410.

[0039] The cylindrical shape of the second shock pad 440 helps to evenly distribute the weight of the motor body and the force generated during operation, reducing the pressure on the fixed structure 130. The outer diameter of the second shock pad 440 is greater than the diameter of the fixed hole 410, which can limit the movement of the second shock pad 440 in the vertical direction. The combination of the first shock pad 420 and the second shock pad 440 provides a double shock absorbing effect, which can more effectively absorb and reduce the vibration generated during the operation of the motor.

[0040] Further, the cross section of the shock absorbing foot pad 400 is in the shape of an I-beam.

[0041] The I-beam cross section has high bending strength and torsional performance due to its unique shape, which makes the shock absorbing foot pad 400 more stable when subjected to vertical and horizontal forces. The I-beam design is commonly used in engineering structures where high load capacity is required. This cross-sectional shape can effectively disperse the load and reduce local stress concentration.

[0042] Further, the first shock pad 420 and the second shock pad 440 are provided with shock holes 450.

[0043] The shock relief holes 450 can reduce the rigidity of the material, so that the first and second shock relief pads 420 and 440 can deform more effectively when subjected to pressure, thereby absorbing more shock energy. The presence of the shock relief holes 450 enables the shock relief pads to be more flexible during compression and recovery, which is particularly effective for reducing high-frequency vibrations. This design can improve the service life of the shock relief pads, as fatigue damage due to stress concentration is reduced. The design of the shock relief holes 450 can reduce the amount of material used, thereby reducing the weight of the shock relief insole 400, which is particularly advantageous for applications where reducing overall weight is desirable.

[0044] In some embodiments, the limiting fastener 300 further comprises an insertion portion 340, which is in the shape of a circular truncated cone.

[0045] The circular truncated cone-shaped insertion portion 340 can be more easily aligned and inserted into the corresponding hole or slot, especially in blind holes or installation environments that are difficult to observe directly, and the guidance of the circular truncated cone shape can improve the accuracy and convenience of installation.

[0046] In some embodiments, the plastic encapsulated motor body 100 is integrally formed with the fixing structure 130.

[0047] The integrally formed design can reduce the number of connection points, thereby reducing potential weak points and failure points, and improving the strength and durability of the overall motor structure. Integrally forming reduces the number of components that need to be manufactured and assembled separately, simplifies the manufacturing process, and improves production efficiency.

[0048] In some embodiments, the fixing structure 130 is provided in multiple numbers and uniformly distributed along the outer wall of the stator 120.

[0049] The multiple fixing structures 130 uniformly distributed along the outer wall of the stator 120 help to more evenly distribute the load of the motor, reduce local stress concentration, and improve the stability and durability of the overall structure.

[0050] In some embodiments, the limiting portion 320 has a diameter greater than that of the fastening portion 330.

[0051] The larger diameter of the limiting portion 320 can provide stronger fastening force, ensuring that the motor remains fixed and is not easily loosened under various working conditions.

[0052] The terms and words used in the above description and claims are not limited to the literal meaning but are merely used by the applicant to enable a clear and consistent understanding of the present utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present utility model is provided only for illustration and not for limitation of the present utility model as defined by the appended claims and their equivalents.
