Description

A dust collecting device, cleaning equipment, central workstation and intelligent cleaning system

【Technical field】

The present invention relates to the technical field of cleaning equipment, in particular to a dust collecting device and a cleaning equipment having the same.

【Background technique】

Sweeping robots are robots capable of performing required cleaning operations in an environment without human guidance. The sweeping robot can automatically dock with the maintenance station to empty its dust box. During the operation of emptying the dust box, the maintenance station is able to suck the dirt collected by the robot vacuum into its interior. The sucked dirt is stored in the accommodating cavity in the maintenance station after passing through the dust extraction pipe inside the maintenance station. The accommodating cavity of the maintenance station is provided with a dust collector for accommodating dirt, and the dust collector is connected to the dust outlet of the dust extraction pipe, so that the dirt discharged through the dust extraction pipe can be accommodated in the dust collector .

In the prior art, there are problems of poor connection stability and reliability and poor sealing effect between the dust collecting member and the dust outlet pipe of the maintenance station. Therefore, it is necessary to improve the prior art to overcome the stated drawbacks in the prior art.

Sweeping robots, also known as automatic cleaners, smart vacuum cleaners, robot vacuum cleaners, etc., are a kind of smart household appliances that can automatically complete the floor cleaning work in the room with certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, vacuuming, and wiping are also classified as sweeping robots. Due to the limited dust storage space of the cleaning robot itself, it is often necessary to perform dust extraction in the central workstation, and at the same time, it can also be charged.

The dust collected by the central workstation needs to be temporarily stored in the dust bag. The current form of the dust bag is shown in Figure 32: there is a card board 7 on the dust bag (not shown), and a card board 7 is opened Circular dust collecting hole 71, a circular soft film 8 is glued on the dust collecting hole 71, and a straight hole 81 is opened on the soft film 8. When collecting dust, the dust collected by the sweeping robot enters into the dust extraction channel of the central workstation under the suction force, and blows the slot 81 into the dust bag by the wind. However, when the dust in the dust bag reaches a certain amount, a new dust bag needs to be replaced. At this time, the old dust bag needs to be taken out from the central workstation, because the dust bag is full of the central workstation cavity before taking it out. When taking out the dust bag, it is inevitable to compress the dust bag to reduce its volume, and the air inside the dust bag will be discharged. Therefore, the dust in the dust bag will be discharged from the slot 21. brought out, resulting in secondary pollution.

Therefore, it is necessary to improve the prior art to overcome the stated drawbacks in the prior art.
