Title: VACUUM CLEANER
Abstract:
Disclosed is a vacuum cleaner, comprising a dirty air inlet, a clean air outlet and an air channel arranged between the dirty air inlet and the clean air outlet. A vacuum generator (8) is arranged inside the air channel. A first filter (23) is arranged in the upper reach of the vacuum generator (8). A second filter (25) is arranged in the upper reach of the first filter (23). The vacuum cleaner further comprises a state sensor (5). When in a first state, the first filter (23) and the second filter (25) are combined to trigger the state sensor (5). When in a second state, the first filter (23) and the second filter (25) are not combined, and the state sensor (5) is not triggered. Missing mounting prevention detection of a main filter and a pre-filter can be realised at the same time by means of a micro-control switch, thereby saving on the cost.
