[0002] With the rapid development of small household appliance technology and the continuous improvement of people's living standards, vacuum cleaners have become one of the essential appliances in people's daily lives.

[0003] Currently, the main unit of a vacuum cleaner is one of its most important components, primarily consisting of a fan and a battery pack that powers the fan. However, current vacuum cleaner main units on the market suffer from insufficient strength in the motor cover, making it prone to loosening and resulting in excessive noise during use, negatively impacting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength vacuum cleaner main unit in order to solve the problem of insufficient strength of the motor cover in the vacuum cleaner main unit.

[0005] To achieve the above objectives, this utility model provides a high-strength vacuum cleaner main unit, which includes:

[0006] The housing includes an end cap and a shell. The end cap has a plurality of first screw holes, a first slot, and a plurality of first plug-in plates. The first screw holes are located between the first slots and the first plug-in plates. The shell is disposed at one end of the end cap, and the inner surface of the shell is provided with a plurality of second slots.

[0007] A motor cover has a plug-in portion at one end, located between the end cap and the housing. A second screw hole is provided on the plug-in portion corresponding to the first screw hole. A first screw passes through the second screw hole and enters the first screw hole. A second plug-in plate on the plug-in portion is inserted into the first slot. A third plug-in plate on the plug-in portion is inserted into the second slot. The first plug-in plate is inserted into the third slot on the motor cover. At least one third screw hole is provided at the end of the motor cover away from the plug-in portion. A second screw on the housing passes through the housing and connects to the third screw hole.

[0008] An electric motor is built into the motor cover, with one end of the motor connected to the end cover and the other end of the motor connected to the motor cover.

[0009] As a further description of the above technical solution:

[0010] Multiple first plug plates are arranged circumferentially along the end cap, and the first plug plates protrude from the surface of the end cap.

[0011] As a further description of the above technical solution:

[0012] The stud or support plate is disposed within the space enclosed by the first plug plate, and the first screw hole is disposed within the stud.

[0013] As a further description of the above technical solution:

[0014] The motor cover is provided with a connecting part corresponding to the position of the first plug plate, and the connecting part is arranged at an angle toward one end of the housing.

[0015] As a further description of the above technical solution:

[0016] The housing has an upwardly protruding space corresponding to the position of the third plug-in plate, and two reinforcing plates are provided in the space.

[0017] As a further description of the above technical solution:

[0018] The second slot is disposed on the reinforcing plate.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the plug-in part on the motor cover is engaged with the first slot through the second plug-in plate, and the first plug-in plate is engaged with the third slot. In this way, plug-in engagement is formed at both ends of the plug-in part, and the third plug-in plate is engaged with the second slot. This forms a multi-plug-in structure between the motor cover and the end cover and the housing, which can improve the connection strength and prevent the motor cover from loosening. At the same time, the motor cover and the end cover and the housing are further tightened with screws, which can further improve the connection strength. There is an overlapping area between the motor cover and the end cover and the housing at the connection point, which can improve the impact resistance and prevent deformation, thus protecting the motor.
