Description

Technical Field

[0001] The present invention relates to the field of vacuum cleaners, and in particular to a cooling device applied to vacuum cleaners and the vacuum cleaner. Background Art

[0002] Vacuum cleaners are a type of cleaning device widely used in modern human life and industrial production, and have been around for over a century. The working principle of a vacuum cleaner is that an electric motor drives the blades to rotate at high speed, creating negative air pressure within a sealed housing. The air then draws in dust through an external suction pipe.

[0003] Temperature requirements for vacuum cleaners are becoming increasingly stringent, a harsh reality for the industry. Existing solutions for reducing temperature in vacuum cleaners primarily include two methods: one involves drilling holes in the body near the large roller to cool the base of the cord reel through ambient air. However, this approach hinders air flow and reduces the temperature at the base of the cord. The other involves drilling holes in the motor housing to allow hot air from the motor's exhaust to cool the area.

[0004] Neither of the two current cooling measures can completely reduce the temperature at the root of the power cord and the PCB heat sink at one time, and the temperature reduction is not ideal. They can only solve the temperature rise problem of each point in a partial manner, but cannot solve the temperature rise problem in multiple parts at one time, so the cooling effect is not ideal. Summary of the Invention

[0005] In view of this, the present invention provides a cooling device for a vacuum cleaner and a vacuum cleaner, which can solve the temperature rise problem in multiple locations at one time.

[0006] On the one hand, the present invention provides a cooling device for a vacuum cleaner, which includes a cooling pipe, the cooling pipe having an air inlet end, the air inlet end connected to a preset air outlet on a motor cover, the cooling pipe also having a first air outlet end and a second air outlet end, the first air outlet end extends to a cord reel, and the second air outlet end extends to a circuit board.

[0007] Furthermore, the cooling pipe is a Y-shaped pipe as a whole.

[0008] Furthermore, the above-mentioned cooling pipe includes a first pipe unit and a second pipe unit, and the first pipe unit and the second pipe unit are connected by a three-way pipe. The free end of the first pipe unit forms the air inlet end, the free end of the second pipe unit forms the first air outlet end, and the free end of the three-way pipe forms the second air outlet end.

[0009] Furthermore, a U-shaped pipeline structure is formed between the first pipeline unit and the second pipeline unit.

[0010] Furthermore, the above-mentioned motor cover is a motor upper cover.

[0011] Furthermore, the motor cover is connected to an air duct, and an air outlet is provided at the end of the air duct.

[0012] Furthermore, a cover plate is provided on the cable reel, and the first air outlet end is connected to the cable reel through the cover plate.

[0013] Furthermore, the cover plate is a circular cover plate, and its surface has semicircular ribs.

[0014] On the other hand, the present invention provides a vacuum cleaner, including a vacuum cleaner main body, wherein the vacuum cleaner main body is further provided with a cooling device applied to the vacuum cleaner as described above.

[0015] The present invention provides a cooling device and a vacuum cleaner for use in a vacuum cleaner, wherein the three ends of the cooling pipe (specifically, a silicone tube) extend to the motor cover, the circuit board and the exhaust cover, and the first air outlet end and the second air outlet end are directly aligned with the root of the power cord of the cord reel and the heat sink of the circuit board to perform synchronous ventilation and cooling treatment. Moreover, all of the physical cooling treatment is performed by utilizing the rapid flow of cold air in the motor cover, which can achieve the goal of reducing the temperature of two points at the same time, and can solve the temperature rise problem in multiple parts at one time, thereby improving the cooling effect.

The free end of the first pipe unit 14 forms an air inlet end 11, the free end of the second pipe unit 15 forms a first air outlet end 12, and the free end of the three-way pipe 16 forms a second air outlet end 13; a U-shaped pipe structure is formed between the first pipe unit 14 and the second pipe unit 15.

[0027] Through the setting of the above structure, the structure that adapts to the internal installation cavity of the vacuum cleaner can be utilized to make the installation structure more compact. At the same time, the synchronous flow of airflow can be achieved, so that the air inlet and outlet volumes are kept consistent, the air volume loss is reduced, and the cooling efficiency is improved. Specifically, a guide ball that slides along the inner wall of the pipe can be installed in the pipe to form a rapid diversion of cooling air to the cooling point and reduce air volume loss.
