Abstract
The invention discloses a spring-free vacuum cleaner indicator, which adopts magnets as elements for controlling the displacement of an indication body and utilizes repulsive force between the magnetswith the same pole to balance pressure difference formed between inside air and outside air when a vacuum cleaner works so as to overcome problems existing in spring-adopting indicators. The indication body and two magnets are arranged in an indicator shell, wherein the indication body has a short cylindrical structure; the two magnets are oppositely arranged through the same pole; and one magnetis fixed at one end of the shell with an air outlet, and the other magnet is fixed on the indication body. When a dust-collecting bag of the vacuum cleaner is full of dust, the rapidly increasing pressure difference in a vacuum cleaner casing allows the two magnets to be completely close, and the indication body moves to a position which can be observed from an observation port. When the obviouscolor and mark of the indication body are observed through the observation port of the indicator shell and a display window at the front of the vacuum cleaner casing, the dust-collecting bag full of dust can be replaced for the normal use of the vacuum cleaner.
