Industrial sweeper provided with an improved device for unclogging the air filter thereof

An industrial sweeper designed to operate by rolling along a floor that is to be cleaned, pushed or pulled, comprising:

• a brush with an axis that is horizontal when considering a position of use of the industrial sweeper on a horizontal floor,
• a collecting pan intended to collect the dirt swept by the brush during operation of the industrial sweeper, the collecting pan being mounted with the ability to pivot about an articulation that is offset laterally from the centre of gravity of the collecting pan between a closed and working position of the industrial sweeper and a wide open position allowing the collecting pan to be emptied,
• a suction turbine situated downstream of the collecting pan to encourage, by suction, the dust to enter the collecting in the closed and working positions,
• two wheels intended to rest on the floor that is to be cleaned,
• an air filter, fixed directly to the collecting pan so that the air filter moves in a same way as the collecting pan moves when the collecting pan pivots, and
• an unclogging mechanism for unclogging the air filter, the unclogging mechanism comprising an end stop designed to block the travel of the collecting pan in the wide open position, the end stop causing an abrupt halt at the end of an opening movement of the collecting pan,
• wherein passage from the closed and working position to the wide open position occurs under the effect of gravity.
