Description

Technical Field

[0001] The present application relates to the technical field of vacuum cleaners, and in particular to a dust collecting port structure of a vacuum cleaner. Background Art

[0002] At present, the structures of the dust collection port of the vacuum cleaner dust collection base station on the market mainly include: ① The dust cup cover spring bounces outward, and is fixed by a lock after being covered. When the vacuum cleaner is placed on the dust collection port of the dust collection base station, the vacuum cleaner dust cup cover lock is triggered, and the vacuum cleaner dust cup cover opens outward under the action of the spring force. At this time, the dust collection base station sucks the garbage in the vacuum cleaner dust cup into the base station dust bag. In this method, the user needs to cover the dust cup cover after the dust collection base station has collected dust. The operation is troublesome and may also dirty the user's hands, resulting in a poor user experience; ② The dust cup cover spring bounces inward, and there is no lock to fix it. The dust cup cover is covered simply by the spring force of the dust cup cover. In this method, when the spring force of the dust cup cover is too large, the opening angle of the vacuum cleaner dust cup cover is small when collecting dust, affecting the dust collection effect. When the spring force of the dust cup cover is too small, garbage may leak out of the dust cup cover when the vacuum cleaner is in use because the dust cup cover is not covered well, resulting in a poor user experience.

[0003] Therefore, a dust cup cover is needed to improve the user experience without the need for the user to cover the dust cup cover; and a dust collection port structure for a vacuum cleaner is needed to prevent garbage from leaking out through the dust cup cover during use of the vacuum cleaner.

[0030] Reference Figure 1-6 A dust collecting port structure of a vacuum cleaner includes: a dust cup 100, a base station dust suction pipe 101, a dust cup cover 102, and a cup cover rotating shaft 103. An opening for connecting the dust cup 100 is provided at the upper end of the base station dust suction pipe 101, so that the dust cup 100 is inserted into the base station dust suction pipe 101 for installation. An opening is provided at the lower end of the dust cup 100, and the dust cup cover 102 is hinged at the lower end opening of the dust cup 100 for sealing the dust cup 100. The cup cover rotating shaft 103 is fixedly arranged on the dust cup cover 102, and rotates with the dust cup 100, so that the dust cup cover 102 has an opening and closing effect, and a torsion spring 104 is sleeved on the cup cover rotating shaft 103 and abuts against the dust cup cover 102 and the dust cup 100. The dust cup cover 102 includes: a cover body 105 arranged on one side of the cup cover rotating shaft 103 and an abutting portion 106 arranged on the other side of the cup cover rotating shaft 103.

[0031] An opening and closing assembly is provided between the base station dust suction pipe 101 and the dust cup 100, which is used to realize the opening and closing of the dust cup cover 102.
