Dust collector

Abstract

The invention relates to a dust collector which comprises a suction head part and an operating rod part, wherein the suction head part and the operating rod part are respectively connected with a machine head part, and the operating rod part thereof is rotatablely connected with the tail or the top of the machine head part. The operating rod part is rotatablely connected with the tail of the machine head part through a connection rotating shaft. A rotating shaft clamping position for limiting the rotating direction of the operating rod part is arranged at the operating rod part or the tail of the machine head part corresponding to the connection rotating shaft. The operating rod part of the invention is rotatablely connected with the machine head part, so that when the dust at the bottom of furniture or other objects is cleaned by a user, the machine head part and the suction head part of the dust collector can be easily extended to the bottom of the furniture or other objects by the user without greatly bending, and the operation thereof conforms to man-machine engineering. The dust collector has simple and reasonable structure, convenient operation and convenient collection.

Description

technical field [0001] The invention relates to a vacuum cleaner. Background technique [0002] In the existing small hand-held charging two-in-one vacuum cleaner, the operating lever cannot be bent. When the user vacuums the bottom of the sofa, the bottom of the wardrobe, etc., the operating lever of the vacuum cleaner needs to be as close to the ground as possible, so that the user has to bend over or squat. It is extremely inconvenient to vacuum these places only when it is down, which is not ergonomic and may even cause damage to the body. In addition, since the operating rod cannot be bent, the packaging of the product is too large, resulting in increased cost and increased storage space. [0003] European Patent Document No. EP0875195B1 discloses a vacuum cleaner, which uses a suction head connected to a connecting bar so that the suction nozzle can be changed to different lengths, so that users of ordinary height can also operate comfortably. The up and down angle i...

However, the scope of use of this vacuum cleaner is limited, and it is usually connected with a power cord when it is working, so it is not easy to carry

At the same time, the dust collection efficiency of the bent tube shaft has a certain influence
