Dust collector with function of being automatically turned off when toppling over or being filled with water

Abstract

The invention discloses a dust collector with the function of being automatically turned off when toppling over or being filled with water. The dust collector comprises a negative pressure toggle device (1), a floating bowl (2), a switch (3), a machine head (4) and a dust collection drum (5). A device composed of the negative pressure toggle device, the floating bowl and the switch is arranged in the machine head of the dust collector, the floating bowl is arranged below an air inlet of a fan inside a filter support, the negative pressure toggle device and the switch are arranged at the upper left portion of the machine head, a bypass air flue is arranged inside the machine head, one end of the bypass air flue is communicated with the negative pressure toggle device, and the other end of the bypass air flue is communicated with the air inlet of the fan. When the dust collection drum is nearly filled with sewage, the floating bowl floats along with the water level to the portion near the air inlet, negative pressure airflow lifts the floating bowl to seal the air inlet, negative pressure jerking motion is generated inside the bypass air flue, the negative pressure jerking motion airflow opens a circuit in the mode that the negative pressure toggle device triggers the switch, and a motor is stopped; when the dust collector topples over, the toppled floating bowl seals the air inlet under the action of the negative pressure airflow, in the same way, the circuit is opened, and the motor is stopped. According to the technical scheme, the dust collector can be used for collecting dust and can also be used for removing muddy water, and is multifunctional and wide in application range.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a vacuum cleaner with the function of automatically shutting off when it is dumped or filled with water, which is used for dust suction and can also be used for sucking sewage slurry. Background technique [0002] Sudden waterlogging in cities with floods, sewage overflows into the room, and after the flood recedes, someone uses a vacuum cleaner to remove the sewage slurry in the room. When the dust collecting bucket of the vacuum cleaner is full of sewage or the vacuum cleaner is dumped due to dragging, if the The motor of the vacuum cleaner is quickly damaged due to the mud water immersing into the fan to overload the motor. The vacuum cleaner in the prior art does not have the function of dumping or automatically shutting off when the water is full. It can only be used for dust collection, and cannot be used for suction. Therefore, the prior art has the problems and deficiencies of single f...

[0002] Sudden waterlogging in cities with floods, sewage overflows into the room, and after the flood recedes, someone uses a vacuum cleaner to remove the sewage slurry in the room. When the dust collecting bucket of the vacuum cleaner is full of sewage or the vacuum cleaner is dumped due to dragging, if the The motor of the vacuum cleaner is quickly damaged due to the mud water immersing into the fan to overload the motor. The vacuum cleaner in the prior art does not have the function of dumping or automatically shutting off when the water is full. It can only be used for dust collection, and cannot be used for suction. Therefore, the prior art has the problems and deficiencies of single function and limited application
