[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 3 shown, a low-cost motor for a small household appliance of the present invention includes a stator core 1. A cylindrical housing 2 is sleeved and arranged around the stator core 1. Both the upper and lower parts of the housing 2 are open. A plurality of convex teeth 3 are arranged on the outer side wall of the housing 2. The plurality of convex teeth 3 are evenly arranged along the outer circumference of the housing 2. The convex teeth 3 are arranged along the axial direction of the housing 2, and the top end of the convex teeth 3 is flush with the top end of the housing 2, and the bottom end of the convex teeth 3 is flush with the bottom end of the housing 2. By setting the housing 2, a plurality of convex teeth 3 are arranged on the outer peripheral surface of the housing 2. During the operation of the motor, heat will be generated by the internal components of the motor housing. Through the housing 2 and the convex teeth 3, effective heat dissipation is carried out. By increasing the heat dissipation area, the heat dissipation efficiency of the motor is improved, thus solving the problem of slow heat dissipation of the motor. This structure can ensure that the motor can still maintain a relatively low temperature during load operation, improving the working efficiency and service life of the motor.

[0027] An adjustment mechanism is provided on the outside of the housing 2. The adjustment mechanism includes two guide plates 4. The two guide plates 4 are fixedly connected to the housing 2. The cross-section of the guide plate 4 is L-shaped. The horizontal parts of the L-shapes of the two guide plates 4 are arranged opposite to each other. A guide post 5 is arranged between the two guide plates 4. A fixing block 6 is sleeved on the guide post 5. The end face of the fixing block 6 abuts against the outer end face of the guide plate 4. By moving along the length direction of the two guide plates 4, the position of the motor can be changed. There are two adjustment mechanisms, and the two adjustment mechanisms are symmetrically arranged along the central axis of the housing 2, which is beneficial to improving the stability when adjusting the position of the motor. The guide post 5 can be installed or disassembled according to requirements.

[0028] The stator core 1 is a straight-chain type stator core 1. The straight-chain type stator core 1 is convenient for winding. After winding is completed, the straight-chain type stator core 1 can be integrated into a complete circle.

[0029] Cover plates 7 are provided at both ends of the housing 2. A plurality of first holes 8 are provided at positions of the housing 2 near the edge. The first holes 8 penetrate through the housing 2. The cover plates 7 are provided with a plurality of protruding parts 9 extending outward. The protruding parts 9 are provided with second holes 10 corresponding to the first holes 8. Bolts are arranged in the first holes 8 and the second holes 10, so that the housing 2 and the cover plates 7 are fixedly connected. The bolts are used to fixedly connect the cover plates 7 and the housing 2. A plurality of through holes 11 are provided on the cover plates 7, which is convenient for the motor to dissipate heat.

[0030] Through the arrangement of the convex teeth 3, the surface area of the motor housing 2 is increased, and heat can be exchanged with the surrounding environment through these convex teeth 3, thereby accelerating the heat dissipation process. Through the increased surface area, the housing 2 of the motor can more effectively transfer the heat generated by the internal parts during operation to the external environment, avoiding the accumulation of heat inside the motor and protecting the motor from overheating damage. This device is not only simple in structure but also low in cost, and is an economical and effective heat dissipation solution. In this way, the motor can operate stably under a wider range of conditions, improving the reliability and service life of the motor.

[0031] In summary, by arranging a plurality of convex teeth 3 on the motor housing 2, through increasing the surface area and optimizing the heat dissipation structure, the heat dissipation efficiency of the motor is effectively improved, the motor is protected from overheating damage, and thus the performance and reliability of the motor are improved.
