Description

Vacuum cleaner system Technical Field The present invention relates to vacuum cleaner systems. Background In general, a vacuum cleaner is a home appliance that sucks small garbage or dust in a manner of sucking air by using electricity and fills it into a dust tub in a product, and is generally called a vacuum cleaner. Such a cleaner may be classified into a manual cleaner in which a user directly moves the cleaner and performs cleaning, and an automatic cleaner in which the user runs autonomously and performs cleaning. The manual cleaners can be classified into cylinder (canister-type) cleaners, upright (upright) cleaners, hand-held cleaners, stick-type (stick-type) cleaners, etc., according to the type of the cleaner. In recent years, a hand-held cleaner and a stick-type cleaner, which are integrally formed with a dust tub and a cleaner body to improve the convenience of use, have been increasingly used. In the cylinder cleaner, a main body and a suction port are connected by a rubber hose (hose) or a pipe (pipe), and a brush may be attached to the suction port according to circumstances. The hand-held cleaner (Hand Vacuum Cleaner) is a cleaner which maximizes portability, but has a limitation in cleaning area because it is required to be squatted down for cleaning due to its short length, although it is lightweight. Thus, it is used for cleaning local places such as desks, sofas or in automobiles. The stick type cleaner can be used standing, and thus cleaning can be performed without bending down. Therefore, the cleaning is facilitated while moving in a wide area. Compared with a handheld dust collector for cleaning a narrow space, the rod dust collector can clean a wider space and can clean a high place which cannot be touched by an adversary. In recent years, stick cleaners have been provided in a module form to actively change the type of the cleaner for various objects and use the same. In recent years, dust collectors have tended to be miniaturized in order to maximize portability. Therefore, the dust bucket of the dust collector produced in recent years has a small capacity, and thus there is a trouble that the user needs to empty the dust bucket frequently. In order to solve the aforementioned problems, a cleaner base station has been developed. The cleaner base station is a device for placing a cleaner ending cleaning and sucking dust collected by the cleaner. That is, the dust collected by the cleaner is continuously collected in the dust collecting part of the cleaner base station, and the user empties the dust collecting part of the cleaner base station. Accordingly, there is an advantage in that the number of times the user empties the dust can be significantly reduced, compared to the case where the dust tub of the dust aspirator is emptied each time. On the other hand, korean laid-open patent publication No. 10-2022-0115253 discloses a cleaning apparatus comprising a vacuum cleaner and a docking station. In the above-mentioned prior patent document, a filter capable of filtering ultrafine dust or the like which is not filtered in the multi-stage cyclone inside the dust tub may be provided. However, since the filter is disposed inside the filter housing in the upper part of the dust tank, it is difficult for a user to separate the filter and clean it. That is, there is a problem in that in order to clean the filter, a user needs to take out the filter from the filter housing after separating the dust bucket. Also, there is a problem in that, in order to clean the multi-stage cyclone, a user needs to open or separate the dust bucket first and then separate the multi-stage cyclone from the dust bucket. In this case, the conventional patent document may be provided with a flow rate changing device. The flow rate changing means is a structure that selectively changes the flow rate of suction air supplied to the dust bucket to change the flow rate of air inside the dust bucket when the suction means of the docking station is driven. That is, the flow rate changing device is configured to supply and block external air to the dust tub in such a manner that air is supplied to the dust tub during a prescribed time and the supply of air is blocked again during the prescribed time, thereby periodically changing the flow rate supplied to the inside of the dust tub. However, in the above-described conventional patent document, since the additional flow rate changing device is configured to change the flow rate supplied to the inside of the dust tub by repeatedly opening and closing the flow path between the trap part and the suction device, although the larger dust accumulated in the inside of the dust tub can be strongly sucked, there is a limitation in removing the dust accumulated in the filter disposed at the upper part of the dust tub and the multi-stage cyclone disposed in the inside of the dust tub.
