[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Reference Figures 1 to 8 The utility model provides a motor, which can be used in household appliances such as air conditioners and washing machines. The existing motor output method is: firstly, the lead wire of the stator winding and the power line 40 are respectively welded and fixed on the circuit board, and then the power line 40 is passed through the motor.

[0039] The motor includes a power cord 40 and a stator assembly (not shown in the figure), the stator assembly is packaged to form a plastic housing (not shown in the figure), the stator assembly has a winding lead (not shown in the figure), one end of the power cord 40 is connected to the winding lead and is packaged and fixed in the plastic housing, and the other end passes through the outlet nozzle 20 to the outside of the plastic housing. The lead-out wires of the stator mouth and the electric control board of the existing motor sealing structure generally adopt two methods. One 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, and the waterproof and airproof effect is poor; the existing rubber wire outlet nozzle with a flat outlet nozzle 22 is used, and the outlet nozzle is squeezed at the outlet by the plastic sealing shell, and the outlet nozzle is deformed to solve the problem of sealing the outlet. The outlet nozzle 20 has an outlet nozzle 22 extended outside the plastic sealing shell, and the outlet nozzle 22 is a flat mouth setting. After the outlet nozzle 22 and the protective cover 50 of the power cord 40 are set together, they are 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 the use environment where the motor needs to be waterproof and airproof with high requirements, the sealing performance is poor.

[0040] In order to solve the above problem, the present solution proposes that, in one embodiment, the motor lead-out assembly 10 includes a lead-out nozzle 20 and an elastic plug 30. The lead-out nozzle 22 of the lead-out nozzle 20 is connected by the elastic plug 30. The elastic plug 30 and the lead-out nozzle 22 are sealed. The power cord 40 passes through the lead-out nozzle 22 and the elastic plug 30. In this way, the lead-out nozzle 22 is connected by the elastic plug 30. The elastic plug 30 plays a filling role and can be deformed due to its elastic properties, thereby achieving sealing of the lead-out 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 arranged on the wire outlet body 21. The wire outlet body 21 is arranged 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 arranged 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 sleeved on the outside of the power cord 40, and the power cord 40 is passed 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 scheme, after the wire outlet nozzle 22 and the protective cover 50 of the power cord 40 are installed together, they are tightened with a cable tie for sealing. However, after extrusion, the part around the cable tie is deformed and lifted, and the gap is large. In the motor environment with high requirements for waterproof and airproof use, the sealing performance is poor. In this scheme, the elastic plug 30 is used as an intermediate piece to respectively connect the wire outlet nozzle 22 of the wire outlet nozzle 20 and the protective cover 50 of the power cord 40. The elastic plug 30 and the wire outlet nozzle 22 are sealedly connected, and the elastic plug 30 and the protective cover 50 are sealed. The power cord 40 passes through the wire outlet nozzle 22, the elastic plug 30 and the protective cover 50. In this way, the wire outlet nozzle 22 and the protective cover 50 are respectively connected 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 utility model adopts an elastic plug 30 as an intermediate piece to respectively connect the wire outlet nozzle 22 of the wire outlet nozzle 20 and the protective cover 50 of the power cord 40. The elastic plug 30 and the wire outlet nozzle 22 are sealedly connected, and the elastic plug 30 and the protective cover 50 are sealedly connected. The power cord 40 passes through the wire outlet nozzle 22, the elastic plug 30 and the protective cover 50. In this way, the wire 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 can be deformed due to its elastic properties, thereby achieving sealing of the wire 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 close 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] In addition, in order to meet the use requirements in different scenarios, the design of the outlet nozzle 22 and the elastic plug 30 can be diversified and innovative. For example, the outlet nozzle 22 can be diversified according to the type and size of the cable to adapt to various types of cables. The elastic plug 30 can be made of different colors and materials to meet the user's needs for beauty and personality.

[0045] Reference Figures 1 to 8 Furthermore, the elastic plug 30 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, not limited to rubber, silicone, etc., 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, not limited to rubber, silicone, etc.

[0047] Furthermore, in order to ensure the sealing performance after the first plug 33 and the outlet nozzle 22 are nested and the sealing performance after the second plug 34 and the protective cover 50 are nested, the first plug 33 and the protective cover 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 the tight connection and sealing effect between the various components. In this design, the interference fit between the first plug 33 and the protective cover 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 and the elastic plug 30 is made of silicone material during long-term use, the interference fit parts may cause the sealing performance to decrease due to wear, and the 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 partition 32 can also facilitate assembly and disassembly.

[0049] Reference Figures 2 to 8 Further, the first plug 33 is columnar, and a first chamfer 331 is provided at the end, and the second plug 34 is columnar, and a second chamfer 341 is provided at the end. The design of the first plug 33 and the second plug 34 also needs to take into account the specifications and shapes of the cables to ensure that they can be closely matched with the cables to prevent the cables from being loosened or damaged during use. When the first plug 33 is inserted into the outlet nozzle 22, the first chamfer 331 plays a guiding role, so that the first plug 33 can smoothly pass through the outlet nozzle 22. At the same time, when the second chamfer 341 is inserted into the protective cover 50, the partition 32 can play a certain limiting role.

[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 portion 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 rectangular 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 to ensure stability at the outlet nozzle 22. The second fastener 62 tightens and seals the protective sleeve 50 and the elastic plug 30 to form 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, clamps, etc.

[0055] Reference Figure 4 , Figure 6 and Figure 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 closely 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, adding a sealing groove improves the stability of the cable tie fixation, and the manufacturing process of the sealing groove is relatively simple, which is easy to mass produce.

[0056] Reference Figure 8Furthermore, 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 sleeve 50 and a wire outlet nozzle 22. When the first fastener 61 is tied to tighten and seal the wire outlet nozzle 22 and the elastic plug 30; when the protective sleeve 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-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.

[0059] The utility model also provides a household appliance, which includes a motor, and the motor applies the motor outlet assembly 10.
