The dirty air entering the cyclone 5 enters the cyclone vessel away from the filter 6. Therefore, the dust-containing air entering the cyclone cylinder 5 forms spiral airflow rapidly, the dust and the like are thrown away from the filter 6 under the action of centrifugal force, the dust is far away from the filter 6, the phenomenon that the filter 6 is blocked due to the fact that the dust is adhered to the filter 6 can be avoided, the service time of the filter 6 is prolonged, and the cleaning frequency of the filter 6 is reduced.

The center of the baffle plate 4 is provided with a through hole corresponding to the air inlet of the dust suction fan 103, and the baffle plate 4 is provided with a cleaning filter screen 401 matched with the annular cavity 102.

The top of the upper cover 1 is provided with a filter screen grille 105, the air outlet of the dust suction fan 103 is communicated with the filter screen grille 105, and the air inlet of the dust suction fan 103 is communicated with the filter 6 arranged in the cyclone separator 5.

The dust collection fan 103 is driven by a motor, and the dust collection fan 103 and the motor are both electrically connected with a PLC (programmable logic controller) of the equipment.

Specifically, the screen grille 105 communicates the suction fan 103 with the outside air. Through PLC controller remote start dust absorption fan 103, the dust passes through air intake 201 and gets into casing 2, and after cyclone 5 and filter 6, the dust falls into collection dirt funnel 7, and the air after the dust removal gets into annular chamber 102 through clean filter screen 401 to discharge behind the filter screen through air outlet 104, carry out secondary filter to the air after the dust removal, avoid the secondary pollution that dust catcher itself during operation produced.

The bag clamping mechanism 8 comprises a fixed block 801, a clamping block 802 and a cylinder 803, the fixed block 801 is installed at the bottom of the dust collecting funnel 7, the cylinder 803 is installed at two sides of the inner surface of the shell 2 and corresponds to the fixed block 801, and the clamping block 802 is connected to an expansion rod of the cylinder 803.

The opposite surfaces of the clamping block 802 and the fixing block 801 are provided with anti-skid grooves.

Specifically, the integrated barrel 3 is detached, the bag clamping mechanism 8 is started to clamp the garbage bag, the electromagnetic valve 701 is started to dump the dust temporarily stored in the dust collecting hopper 7 into the garbage bag, and the electromagnetic valve 701 is closed after the detection device on the electromagnetic valve 701 detects that the garbage bag is full. The arrangement of the dust collecting funnel 7 can ensure the ventilation capability of the dust collector and avoid the reduction of the dust collecting capability. The bag clamping mechanism 8 is also convenient for dumping garbage after dust collection of small houses at each time, and the garbage bag is taken down, so that the situation that when the dust bag is cleaned, dust flies around when the shell is opened is avoided.

The action process of the utility model is as follows:

firstly, the central dust collector is arranged on a balcony or a storage room, the air inlet 201 is connected with a dust collection pipeline of a central dust collection system, the dust collection fan 103 is turned on through a remote switch, indoor air mixed with dust enters the shell 2 from the pipeline of the central dust collection system through the air inlet 201, the indoor air is filtered and separated through the cyclone separator 5 and the filter 6, the dust falls into the dust collection funnel 7, and the air after dust removal enters the annular cavity 102 through the cleaning filter screen 401 and is discharged after passing through the filter screen of the air outlet 104.

Dismantle integrated bucket 3, start 8 clamping disposal bags of bag mechanism, start solenoid valve 701 will be kept in the dust of collecting hopper 7 and pour into in the disposal bag, the detection device on the solenoid valve 701 detects the disposal bag and closes solenoid valve 701 after filling up, takes off the disposal bag packing, can handle with domestic waste together.

On the premise of ensuring the suction force of the dust collector, the dust collector realizes that a user can empty a small amount of dust for multiple times, and also avoids the situation that the dust overflows when the user replaces or cleans the dust collector.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
