Patents such as Chinese Patent Nos. CN 103961025A, WO 2020011238A, CN 110811414A, CN 111588306A, CN 211933876U and CN 209404622U disclose the technique for storing a dust suction device.
Taking Chinese Patent No. CN 103961025A as an example, Chinese Patent No. CN 103961025A describes that the main structure of the dust suction device comprises a dust collection barrel and a body element, the body element has a head housing stacked on the dust collection barrel, a motor disposed in the head housing, a filter element located in the dust collection barrel, and a quick-installation structure disposed on the head housing, the quick-installation structure enables the dust suction device to switch between a first state and a second state. Wherein, in the second state, the filter element is connected to the head housing, and the head housing is stacked above the dust collection barrel through the quick-installation structure, so that the dust suction device can perform a dust suction operation; in the first state, the filter element is removed from the head housing, and is independently placed in the dust collection barrel relative to the head housing, and the head housing is suspended on the opening of the dust collection barrel in an upside down posture through the quick-installation structure, so that the head housing is accommodated in the dust collection barrel. However, when the conventional dust suction device enters the first state, the head housing and the motor will be suspended on the opening of the dust collection barrel at the same time, causing the quick-installation structure to bear a considerable weight. When the structural stability of the quick-installation structure is insufficient, it is easy to cause the head housing to collide with the filter element accommodated in the dust collection barrel. Furthermore, the storage method of the conventional dust suction device is likely to make some components on the head housing still expose outside the dust collection barrel, resulting in the head housing cannot be completely accommodated.
A main object of the invention is to solve the problem that conventional dust suction devices are not conducive to storage.

It is known from the above that the at least one shell outer diameter 511 of the shell 51 of the invention is smaller than the opening diameter 121, so that when the dust suction assembly 50 is in the use state, the dust suction assembly 50 cannot be placed above the dust collection barrel 10 alone. The dust suction assembly 50 is stacked on the dust collection barrel 10 through disposing and using the supporting ring 30 as a base. When the dust suction assembly 50 enters the storage state, after the dust suction assembly 50 is placed in the barrel inner space 11, the top edge of the dust suction assembly 50 does not exceed the assembling opening 12, so that the dust suction assembly 50 will not be exposed outside of the dust collection barrel 10 in order to reduce a volume of the dust suction device 100 and facilitate transportation of the dust suction device 100. Compared with the conventional technique, the invention is more than simply stores a body component upside down, but completely stores the dust suction assembly 50 in the dust collection barrel 10, and effectively solves the problem of relying on a quick-installation structure to suspend a head housing on the conventional dust suction devices.
