Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of suction devices, and in particular relates to a portable electric suction device. Background Art
[0002] The electric suction device creates a negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the material outside the suction head toward the suction head, thereby achieving the "suction" effect. Since the electric suction device uses electricity as a power source, it has the characteristics of high power, strong suction, wide application range and good mobility.
[0003] At present, electric suction devices on the market are generally equipped with a body that is easy to move, so that the container for collecting liquids is placed on the vehicle. Since there is a negative pressure pipeline of appropriate length between the container and the main unit of the electric suction device, containers of different heights are prone to mismatch with the negative pressure pipeline during use. This will cause the negative pressure pipeline to be pulled when it is compact or bend and swing when it is redundant. In addition, in complex application scenarios of negative pressure liquid suction, both the vehicle body and the container will be bumped, causing shaking and displacement. Utility Model Content
