Vacuum cleaner

Abstract

A vacuum cleaner is provided. The vacuum cleaner includes a main body unit having a driving unit for generation suction; a main body; a dust separation unit that is provided in the main body to separate dusts from air and provided with a dust exhaust portion through which the separated dusts are exhausted; a dust storage chamber that is provided with a dust inflow portion through which the dusts exhausted from the dust exhaust portion is introduced; and a mounting unit that is formed on the main body and on which the dust storage chamber is mounted, wherein the dust exhaust portion and the dust inflow portion contact each other by a pressing force by which the dust storage chamber is mounted on the mounting unit, thereby preventing the air from leaking.

Description

technical field [0001] The present invention relates to a vacuum cleaner, in particular to such a vacuum cleaner, which has a dust collecting unit with an improved structure, so that it is more convenient for users to use. Background technique [0002] In general, a vacuum cleaner is a device capable of sucking dust-laden air using a suction force generated by a motor installed on a main body, and filtering the dust in a dust filter device. [0003] Vacuum cleaners are divided into cylinder type and upright type. The cylinder type vacuum cleaner includes a main body and a suction nozzle connected to the main body by a connecting pipeline. A cylinder type vacuum cleaner includes a main body and a suction nozzle integrally formed with the main body. [0004] Meanwhile, a conventional cyclone vacuum cleaner includes a suction nozzle for sucking air containing dust, a main body unit communicated with the suction nozzle, a dust collection unit for filtering out dust contained i...

AI Technical Summary

Problems solved by technology

[0009] However, since the conventional dust collection unit includes both the main cyclone unit and the sub-cyclone unit, the volume and weight of the vacuum cleaner are increased

Therefore, it is difficult for the user to hold the vacuum cleaner

This problem becomes more serious when a large amount of dust is stored in the dust collection unit

[0010] Secondly, since the traditional dust collection unit includes both the main cyclone unit and the sub-cyclone unit, the sub-chamber leads to a reduction in the space of the main chamber structurally

As a result, the dust collection volume of the main chamber is reduced, and thus the user has to empty the dust collection unit more frequently

[0011] Third, since the traditional dust collection unit includes both the main cyclone unit and the sub-cyclone unit, the internal structure of the dust collection unit is complicated, and thus it is difficult to clean or flush the inside of the dust collection unit

[0012] Fourth, since the traditional dust collection unit includes both the main cyclone unit and the sub-cyclone unit, it is expensive to manufacture molds for the production of the dust collection unit

Moreover, when the dust collection unit leaks or is damaged, the dust collection unit must be replaced as a whole

[0013] Fifth, since the sub-chambers are arranged around the main body, it is difficult for the user to determine the amount of dust stored in the main chamber with the naked eye

[0014] Sixth, during emptying the dust collection unit or dumping the dust in the dust collection unit after separating the dust collection unit from the main body, the inside of the room may be recontaminated

Therefore, the room needs to be cleaned again
