In some specific examples of the present utility model, a second filter assembly may be disposed in the main body 10, where the second filter assembly includes a first filter, a second filter, and a motor pre-filter, and a first dust collecting space is disposed between the first filter and the second filter, and a second dust collecting space is disposed between the second filter and the motor pre-filter, and the first dust collecting space and the second dust collecting space may be used to collect dust filtered from an airflow.

The airflow path of the cleaning apparatus 100 may be: the air flow enters the air inlet pipe from the inlet 60, dust and air enter the main body 10 from the side part of the main body 10, the dust falls into the first dust collecting space after being filtered by the first-stage filter, the air flow containing a small amount of dust continuously enters the second-stage filter for filtering, the filtered fine dust falls into the second dust collecting space, the air flow continuously enters the motor pre-filter for filtering and then flows towards the motor, and finally the air flow passes through the motor post-filter and is discharged from the outlet 70.

Specifically, dust and air enter from the suction port 60, enter the main body 10 tangentially through the inlet 60, and spin down along the sidewall of the main body 10 to the first dust collecting space of the main body 10 under the centrifugal force. The lower part of the filtering net cover (namely the first-stage filter) is provided with a flanging which forms a certain angle with the horizontal direction (wherein the horizontal direction is the same as the axis direction), and the downward flanging of the filtering net cover (namely the first-stage filter) can prevent dust entering the bottom by centrifugal force from entering the multi-cone cyclone (namely the second-stage filter) again, so that the total amount of the dust entering the multi-cone cyclone (namely the second-stage filter) is effectively reduced. Part of the dust passes through the filter screen (i.e. the first-stage filter) and enters the multi-cone cyclone (i.e. the second-stage filter); similarly, under the action of centrifugal force, dust rotates downwards to the second dust collecting space at the bottom along the wall of the multi-cone cyclone (namely the second-stage filter), and gas enters the motor pre-filter through the porous wind-passing channel at the dust-gas separating port and then enters the motor, and is filtered by the motor post-filter and then is discharged. The cyclone filter is arranged twice, the cyclone mechanism with multiple cones is adopted for the secondary filtering, the separation efficiency of dust and air can be greatly increased, the frequency of cleaning the filter is reduced, and the service life of the filter is prolonged.

The scheme is that the motor pre-filter and the motor post-filter (namely the first filter assembly 30) are arranged, so that the motor air inlet end and the motor air outlet end are both provided with the filter, and the separation efficiency is improved.

This case is through setting up the display screen on support 31 to utilize the structure installation motor post-filter of support 31, rational utilization's space makes complete machine structure compacter, and avoided the display screen to drop the damage.

The hand-held cleaner (i.e., cleaning apparatus 100) includes a main body portion 10, a dirt cup connected to the main body portion 10, a handle, a motor, a battery, an air intake, a motor pre-filter, a motor post-filter (i.e., first filter assembly 30). The hand-held dust collector can adopt side air inlet, so the air inlet is positioned at one side of the dust cup. The motor pre-filter and the motor post-filter are respectively positioned at the front part and the rear part of the motor on the airflow path for respectively filtering airflow, and the motor pre-filter is positioned in the dust cup and at least partially positioned in the first-stage filter.

The post filter of the motor can be overlapped with the motor in space according to actual conditions. The dust cup, the motor and the motor post filter are sequentially arranged along the longitudinal axis direction of the dust cup. The battery supports the whole handheld dust collector, the handle is located between the motor and the battery, the axis of the handle does not penetrate through the motor, and the motor is more rear relative to the axis of the handle. The hand-held dust collector is provided with a far end and a near end which are opposite, the air inlet is positioned at the far end, and the motor post-filter is positioned at the near end.

The dust cup comprises a cup body, a dust cup cover for pouring dust, a first-stage filter and a second-stage filter, wherein the first-stage filter is arranged in the cup body, the surface of the first-stage filter is provided with a plurality of through holes and is used for filtering dust with larger granularity, the second-stage filter is a multi-cone cyclone, the second-stage filter comprises a plurality of small cones, and the small cones are arranged in the dust cup in a surrounding manner and are positioned at the downstream of the first-stage filter. The dust cup is also provided with an unlocking button for unlocking the dust cup cover.

The motor pre-filter is located inside the first stage filter. The dust collector is provided with a motor pre-filter handle for taking out the pre-filter along the longitudinal axis of the dust cup, the pre-filter handle is arranged at a position close to the dust pouring cover, and the pre-filter is disassembled towards a direction far away from the dust cup cover. The motor post filter can be detached from the rear, so that the motor pre filter and the motor post filter can be conveniently cleaned. The motor pre-filter is arranged coaxially with the first stage filter. The motor pre-filter comprises a filter support 31 and filter cotton arranged on the filter support 31, and air flow enters the interior through a plurality of through holes on the filter support 31 after being filtered by the filter cotton and flows from an interior channel towards the motor.

As stated before, in order to make the motor pre-filter disassemble and clean quickly, the motor pre-filter is designed to disassemble quickly (without disassembling the whole dust cup), the motor pre-filter is positioned at the middle position of the dust cup, the upper part of the motor pre-filter is communicated with the fan assembly through a sealing ring, and the air after dust and gas separation enters the pre-filter through a porous air passage and then enters the motor to be discharged, usually, the motor pre-filter has a small amount of fine dust attached to the outer wall of the motor pre-filter, when the pre-filter needs to be cleaned, a handle of the filter is screwed by hand to be pulled out at the position of an opening at the bottom of the dust cup, and the motor pre-filter can be cleaned or replaced quickly under the condition that any other parts are not disassembled, so that the convenience and satisfaction of users are greatly improved.
