The inner shell 2 is provided with a plurality of heat dissipation holes 21 arranged along its length direction and between two adjacent heat dissipation fins 3. Preferably, the heat dissipation holes 21 are strip holes. Such a design of the heat dissipation holes 21 helps the motor body to obtain good heat dissipation from back to front, and the heat dissipation effect is better. The inner peripheral wall of the outer shell 1 is provided with fin grooves 11, which are the same in number as the heat dissipation fins 3 and can be matched and inserted one by one; specifically, the fin grooves 11 penetrate the rear end surface of the outer shell 1 and extend from the rear end surface of the outer shell 1 to the front end of the outer shell 1, so that the heat dissipation fins 3 can be inserted into the fin grooves 11 from the rear end surface of the outer shell 1, which is convenient for assembly. When a number of heat dissipation fins 3 are matched and inserted into the fin grooves 11 one by one, the inner shell 2 is located in the outer shell 1, and two adjacent heat dissipation fins 3 form a heat dissipation duct 6 with the inner peripheral wall of the outer shell 1 and the outer peripheral wall of the inner shell 2; the air guide cover 4 is detachably connected to the outer shell 1 and is respectively connected to the inner cavity of the inner shell 2 and the heat dissipation duct 6.

[0035] The detachable and cleanable motor air duct shell structure is combined by setting an outer shell 1, an inner shell 2, heat dissipation fins 3 and a guide cover 4. A plurality of air ducts and heat dissipation holes 21 are set on the outer shell 1, the inner shell 2 and the heat dissipation fins 3, and combined with the guide cover 4, the overall heat dissipation of the motor is accelerated to form an efficient heat dissipation effect. At the same time, the inner shell 2 and the plurality of heat dissipation fins 3 are formed into an integral structure, and the heat dissipation fins 3 are adapted and detachably connected with the fin slots 11, so that the heat dissipation fins 3 and the inner shell 2 can be easily disassembled for cleaning, which solves the problem that the traditional fixed air duct is not easy to clean and improves the heat dissipation efficiency and service life of the motor. And the guide cover 4 and the outer shell 1 are detachably connected, so that the entire motor air duct shell structure can be completely disassembled when necessary, which is convenient for thorough cleaning and maintenance of the interior.

[0036] In order to improve the heat dissipation efficiency of the detachable and cleanable motor air duct shell structure, the detachable and cleanable motor air duct shell structure also includes a fan shell 5 for installing a heat dissipation fan; the outer shell 1, the air deflector 4 and the fan shell 5 are detachably connected together. A fan is installed in the fan shell 5 to provide wind force to the air deflector 4, accelerate the overall heat dissipation of the motor, and improve the overall heat dissipation efficiency of the motor. At the same time, the outer shell 1, the air deflector 4 and the fan shell 5 are detachably connected together, so that the entire motor air duct shell structure can be completely disassembled when necessary, which is convenient for thorough cleaning and maintenance of the interior.

[0037] In this embodiment, a snap-in portion 8 is provided on the front end surface of the fan housing 5; a snap-in through hole 44 is provided on the air duct 4 at a position corresponding to the snap-in portion 8, through which the snap-in portion 8 can pass; a snap-in groove 12 adapted to the snap-in portion 8 is provided on the rear end surface of the outer shell 1; the snap-in portion 8 passes through the snap-in through hole 44 and is snap-fitted into the snap-in groove 12 so that the fan housing 5 and the air duct 4 can be detachably connected to the outer shell 1. The snap-in portion 8 passes through the snap-in through hole 44 and is snap-fitted into the snap-in groove 12 so that the fan housing 5, the air duct 4 and the outer shell 1 can be detachably connected, so that the entire motor air duct housing structure can be completely disassembled when necessary, which is convenient for thorough cleaning and maintenance of the interior.

[0038] In this embodiment, the air guide cover 4 includes a cover ring body 41, a shaft body 42 and a guide vane 43; the shaft body 42 is located in the center of the cover ring body 41; the cover ring body 41 and the shaft body 42 are connected by the guide vane 43; a plurality of guide vanes 43 are evenly arranged around the central axis of the shaft body 42. Preferably, the guide vane 43 has a guide slope 431 inclined toward the direction of the outer shell. The air guide cover 4 is formed by arranging the cover ring body 41, the shaft body 42 and the guide vane 43, and the guide vane 43 has a guide slope 431 set as required, which facilitates the diversion to the inner cavity of the inner shell 2 and the heat dissipation duct 6, accelerates the overall heat dissipation of the motor, and forms an efficient heat dissipation effect. Especially after the fan is installed in the fan shell 5, the heat dissipation effect is better.

[0039] In this embodiment, the detachable and cleanable motor air duct shell structure is made of zinc alloy. The motor air duct shell structure made of zinc alloy has excellent mechanical properties, and its strength, hardness and toughness are all excellent. This enables the motor shell made of zinc alloy to withstand higher working pressure and impact force, and effectively protect the parts inside the motor from damage. In addition, zinc alloy also has good wear resistance and corrosion resistance, and can maintain a long service life in harsh environments. At the same time, compared with traditional metal materials, the density of zinc alloy is lower, so the motor air duct shell structure made of zinc alloy has a lighter weight. The lightweight design not only helps to reduce the overall weight of the motor and reduce energy consumption, but also helps to improve the operating efficiency of the motor. In addition, the lightweight motor air duct shell structure can also reduce transportation and installation costs and improve the market competitiveness of the product. On the other hand, the motor will generate electromagnetic radiation during operation, which will have a certain impact on the surrounding environment and equipment. As a good conductive material, zinc alloy can effectively shield electromagnetic radiation and reduce the interference of the motor to the surrounding environment. This is of great significance for ensuring the stable operation of the motor and improving the safety of the equipment. Therefore, the motor air duct shell structure made of zinc alloy has many advantages, including excellent mechanical properties, lightweight design concept, excellent electromagnetic shielding performance and beautiful appearance design, etc. Of course, the detachable and cleanable motor air duct shell structure is not limited to zinc alloy, and can also be made of other materials, such as aluminum alloy, stainless steel, etc.
