[0038] 1 to 8 , the present application provides a motor that can be used in household appliances such as air conditioners and washing machines. Conventional motor wiring methods include first soldering the stator winding leads and the power cord 40 to a circuit board, and then threading the power cord 40 out of the motor.

[0039] The motor includes a power cord 40 and a stator assembly (not shown). The stator assembly is encapsulated into a plastic housing (not shown). The stator assembly has winding leads (not shown). One end of the power cord 40 is connected to the winding leads and encapsulated and fixed within the plastic housing. The other end of the power cord 40 passes through the lead nozzle 20 and exits the plastic housing. Existing motor sealing structures generally use two methods to connect the leads between the stator opening and the electronic control board. One method is to use a hard plastic wire clamp made of nylon or PBT material, but the wire clamp made of hard plastic material cannot fit tightly with the lead wire of the electric control board, and the contact between the lead wire and the wire protection sleeve is also difficult to be completely sealed, resulting in poor waterproof and airproof effect; the existing rubber wire outlet nozzle uses a flat-mouthed wire outlet nozzle 22, which is squeezed at the wire outlet by the plastic shell, causing the wire outlet nozzle to deform, thereby solving the problem of sealing the wire outlet. The wire outlet nozzle 20 has a wire outlet nozzle 22 extending from the outside of the plastic shell, and the wire outlet nozzle 22 is a flat-mouthed setting. After the wire outlet nozzle 22 is sheathed on the protective sleeve 50 of the power cord 40, it is tightened with a cable tie for sealing. However, after squeezing, the part around the cable tie is deformed and warped, and the gap is large. In an environment where the motor needs to be used with high requirements for waterproof and airproof, the sealing performance is poor.

[0040] In order to solve the above problems, in one embodiment, the motor wire outlet assembly 10 includes a wire outlet nozzle 20 and an elastic plug 30. The elastic plug 30 is used to connect the wire outlet nozzle 22 of the wire outlet nozzle 20. The elastic plug 30 and the wire outlet nozzle 22 are sealed. The power cord 40 passes through the wire outlet nozzle 22 and the elastic plug 30. In this way, the wire outlet nozzle 22 is connected through the elastic plug 30. The elastic plug 30 plays a filling role, and because of its elastic properties, it can produce deformation, thereby achieving sealing of the wire outlet nozzle 22.

[0041] In another embodiment, the motor wire outlet assembly 10 includes a wire outlet nozzle 20, a protective cover 50 and an elastic plug 30. The wire outlet nozzle 20 is made of elastic material. The wire outlet nozzle 20 includes a wire outlet body 21 and a wire outlet nozzle 22 provided on the wire outlet body 21. The wire outlet body 21 is provided at the wire outlet of the motor. The power cord 40 of the motor passes through the wire outlet body 21 and passes through the wire outlet nozzle 22. The wire outlet body 21 is provided at the wire outlet and the wire outlet body 21 is deformed by squeezing the plastic package shell to achieve sealing at the wire outlet. The protective cover 50 is provided on the outside of the power cord 40. The power cord 40 passes through the elastic plug 30. The two ends of the elastic plug 30 are respectively sealed and connected to the protective cover 50 and the wire outlet nozzle 22. Compared with the existing solution, after the outlet nozzle 22 and the protective cover 50 of the power cord 40 are put together, they are tightened with a cable tie for sealing. However, after squeezing, the part around the cable tie is deformed and lifted, and the gap is large. In the motor's use environment with high requirements for waterproof and airproof, the sealing performance is poor. This solution uses an elastic plug 30 as an intermediate piece to connect the outlet nozzle 22 of the outlet nozzle 20 and the protective cover 50 of the power cord 40 respectively. The elastic plug 30 and the outlet nozzle 22 are sealed. The elastic plug 30 and the protective cover 50 are sealed. The power cord 40 passes through the outlet nozzle 22, the elastic plug 30 and the protective cover 50. In this way, the outlet nozzle 22 and the protective cover 50 are connected respectively by the elastic plug 30. The elastic plug 30 plays a filling role, and because of its elastic performance, it can be deformed. Therefore, when the cable tie is used to tighten and seal, the elastic plug 30 can be deformed, thereby avoiding the appearance of gaps.

[0042] The technical solution of the present application adopts an elastic plug 30 as an intermediate piece to respectively connect the outlet nozzle 22 of the outlet nozzle 20 and the protective cover 50 of the power cord 40. The elastic plug 30 and the outlet nozzle 22 are sealed, and the elastic plug 30 and the protective cover 50 are sealed. The power cord 40 passes through the outlet nozzle 22, the elastic plug 30 and the protective cover 50. In this way, the outlet nozzle 22 and the protective cover 50 are respectively connected through the elastic plug 30. The elastic plug 30 plays a filling role, and due to its elastic properties, it can produce deformation, thereby achieving sealing of the outlet nozzle 22 and the protective cover 50.

[0043] Specifically, the cross-section of the outlet nozzle 22 is circular, and the elastic plug 30 is adapted to the outlet nozzle 22. The outlet nozzle 22 is circular, and the elastic plug 30 is also circular. The circular design of the circular outlet nozzle 22 and the elastic plug 30 ensures a tight fit between the outlet nozzle 22 and the elastic plug 30. This design not only improves the overall aesthetics of the product, but also has good practicality. On this basis, the material selection of the elastic plug 30 is also crucial. Generally speaking, the elastic plug 30 is made of a material with good elasticity and wear resistance, such as silicone, rubber, etc. These materials not only ensure the durability of the elastic plug 30 during use, but also ensure the sealing performance.

[0044] Furthermore, to meet the needs of different scenarios, the designs of the cable outlet nozzle 22 and the elastic plug 30 can be diversified and innovative. For example, the cable outlet nozzle 22 can be designed in a variety of ways based on the type and size of the cable to accommodate various types of cables. The elastic plug 30 can also be made of different colors and materials to meet the user's aesthetic and personalized needs.

[0045] 1 to 8 , the elastic plug 30 further includes a partition 32 , and a first plug 33 and a second plug 34 located on opposite sides of the partition 32 . The first plug 33 is connected to the outlet nozzle 22 , and the second plug 34 is connected to the protective cover 50 .

[0046] Specifically, the outlet nozzle 20 is made of a highly elastic polymer material, such as rubber or silicone, and the outlet body 21 and the outlet nozzle 22 are integrally formed. The elastic plug 30 is made of a highly elastic polymer material, such as rubber or silicone.

[0047] Furthermore, to ensure the tightness of the first plug 33 and the outlet nozzle 22 after being nested, and the tightness of the second plug 34 and the protective sleeve 50 after being nested, the first plug 33 and the protective sleeve 50 are interference fit; the second plug 34 and the outlet nozzle 22 are interference fit. It can be understood that the interference fit is set to ensure a tight connection and sealing effect between the various components. In this design, the interference fit between the first plug 33 and the protective sleeve 50, and the second plug 34 and the outlet nozzle 22 plays a key role. At the same time, considering that the outlet nozzle 20 is made of silicone material during long-term use, and the elastic plug 30 is made of silicone material, the interference fit components may cause the sealing performance to deteriorate due to wear, and silicone material has good wear resistance.

[0048] Furthermore, the outlet nozzle 22 is sleeved with a first plug 33 and is close to the partition 32; the protective cover 50 is sleeved with a second plug 34 and is close to the partition 32. In addition to separating the first plug 33 and the second plug 34, the setting of the partition 32 can also facilitate assembly and disassembly.

[0049] Referring to Figures 2 to 8 , the first plug 33 is cylindrical and has a first chamfer 331 at its end. The second plug 34 is cylindrical and has a second chamfer 341 at its end. The design of the first and second plugs 33, 34 also takes into account the specifications and shape of the cable to ensure that they can closely match the cable and prevent the cable from loosening or being damaged during use. When the first plug 33 is inserted into the outlet nozzle 22, the first chamfer 331 serves as a guide, allowing the first plug 33 to pass smoothly through the outlet nozzle 22. At the same time, the second chamfer 341 can provide a certain limit to the partition 32 when inserted into the protective cover 50.

[0050] In other embodiments, the first plug 33 and the second plug 34 may also be in other shapes, such as a bullet shape or an arrow shape.

[0051] Furthermore, the area of ​​the partition 32 is larger than the areas of the outlet nozzle 22 and the protective cover 50 .

[0052] In one embodiment, the partition 32 is disc-shaped, and the first plug 33 and the second plug 34 are respectively located on two sides of the partition 32 , like a “two-headed spinning top”.

[0053] In one embodiment, the partition 32 is in other shapes, such as a square, a rectangle, a diamond, etc.

[0054] In one embodiment, the motor outlet assembly 10 further includes a first fastener 61 and a second fastener 62. The first fastener 61 tightens and seals the outlet nozzle 22 and the elastic plug 30; the second fastener 62 tightens and seals the protective sleeve 50 and the elastic plug 30. The first fastener 61 and the second fastener 62 further ensure the sealing of the outlet nozzle 22 to prevent loosening. The first fastener 61 tightly seals the outlet nozzle 22 and the elastic plug 30, ensuring stability at the outlet nozzle 22. The second fastener 62 tightens and seals the protective sleeve 50 and the elastic plug 30, forming a complete protection system. The second fastener 62 makes the seal between the protective sleeve 50 and the elastic plug 30 tighter, further improving the protection performance. The first fastener 61 and the second fastener 62 can be cable ties or clamps, hoop, etc.

[0055] 4, 6 and 7, in one embodiment, an annular groove is provided at the end of the outlet nozzle 22, and a first fastener 61 is provided in the annular groove and tightens and seals the outlet nozzle 22 and the elastic plug 30; the protective cover 50 and the elastic plug 30 are tightened and sealed by a second fastener 62. The design of the annular groove enables the first fastener 61 to better fit tightly with the outlet nozzle 22, further enhancing the sealing effect. This design not only improves the stability of the outlet nozzle 22, but also avoids potential safety hazards caused by looseness. In addition, compared with other solutions, the addition of a sealing groove improves the stability of the cable tie fixation, and the manufacturing process of the sealing groove is relatively simple, making it easy to mass-produce.

[0056] Referring to Figure 8, further, the elastic plug 30 is penetrated by a plurality of wire holes 31, and the plurality of wire holes 31 are evenly distributed in a ring shape. The power cord 40 passes through the elastic plug 30 through the wire holes 31, and the two ends of the elastic plug 30 are respectively penetrated by a protective cover 50 and a wire outlet mouth 22. When the first fastener 61 is tied to tighten and seal the wire outlet mouth 22 and the elastic plug 30; when the protective cover 50 and the elastic plug 30 are tightened and sealed by the second fastener 62, the wire holes 31 are arranged in a ring shape. Compared with other arrangements, the force is more uniform and the damage to the power cord 40 is less.

[0057] Furthermore, the diameter of the wire hole 31 is 1.6 mm to 1.8 mm, which can not only meet the requirements of the installation of most types of power cords 40, but also ensure the quality of the elastic plug 30.

[0058] In one embodiment, the protective cover 50 is made of polyvinyl chloride; in another embodiment, the protective cover 50 is made of silicone or rubber.
