The upper part of the left side surface of the machine shell 12 is provided with an air inlet used for communicating the dust cup mechanism 2 and the motor 4. In order to shorten the air flow path and reduce the energy consumption, the motor 4 is located above the handle 11 and has a height corresponding to the height of the air inlet. In addition, a switch for opening and closing the motor 4 is attached to the handle 11. The connection mode and circuit principle of the switch and the motor 4 are common knowledge in the art, and the description of this embodiment is omitted. The casing 12 is further provided with an air outlet 12a for exhausting air and dissipating heat, and the air outlet 12a is adapted to the position of the motor 4.

The dirt cup mechanism 2 includes a cup body 21, a cover 22, a filter element 23, a filter 24, and a cyclone 25. In the present embodiment, the cup body 21 and the filter 24 are each shaped as a hollow cylinder. It should be noted that the cylinder of the present embodiment does not need to be a cylinder in a strict sense, for example, the bottom edge of the cup body 21 is cut into a chamfered edge, and the filter 24 is provided with a projection. The top of the cup body 21 is provided with an opening, the cover body 22 is detachably mounted on the top of the cup body 21, and the left side of the cup body 21 is provided with a hole for connecting with the adsorption mechanism 3. The side of the cover 22 is provided with an air outlet 22a communicating with the motor 4. Both the filter 24 and the cyclone 25 are disposed inside the cup 21.

The cyclone passage 251a of the cyclone part 251 communicates with the inside of the filter 24. The bottom end of the barrel portion 252 is connected to the bottom of the cup body 21. In addition, the cylinder 252 is provided with a guide slope 252a, the guide slope 252a functions to guide movement of dust during cyclone separation so that the dust moves downward against the guide slope 252a, and the guide slope 252a makes a partial region of the cylinder 252 present a funnel shape with a large top and a small bottom.

The filter 24 functions to block large foreign materials such as paper sheets and to limitedly block large particles of dust. The side of the filter 24 is provided with filtration pores. The filter 24 is fitted around the cyclone 25, and a certain space is provided between the inner wall of the filter 24 and the cyclone 25 to facilitate the gas circulation. As described above, the interval between the filter 24 and the cyclone 25 is communicated with the cyclone passage 251a.

The filter cartridge 23 opens through the top of the cup 21. A cavity for accommodating the filter element 23 is arranged in the cover 22. When the cover 22 is opened, the filter element 23 can be easily taken out. Specifically, the filter element 23 includes an annular support portion 231 and a filter portion 232. The annular support 231 and the filter part 232 are both cylindrical, and the top of the annular support 231 is open. The diameter of the annular support portion 231 is larger than that of the filter portion 232, the annular support portion 231 is located at an upper portion of the filter portion 232, and the annular support portion 231 and the filter portion 232 are integrally formed. The annular support 231 is placed on the cyclone 25 and connected to the cyclone 25 by fasteners (not shown in the figures). The fasteners may be selected from screws, bolts, etc., which are well known in the art and will not be described in detail herein. The fastening means prevents locking of the filter element 23 and the cyclone 25 and loosening of the filter element 23 and the cyclone 25 during dust extraction. When the filter element 23 is disassembled, the fastener is disassembled, which is simple and fast. The filter unit 232 passes through the cyclone unit 251 and extends into the cylindrical unit 252, and the filter unit 232 is coaxial with the cylindrical unit 252. A filter opening 232a is formed in the lower portion of the filter portion 232, and the gas in the cyclone 25 enters the filter element 23 through the filter opening 232a. The bottom surface of the filter part 232 is provided with a dust blocking member 232b. The dust blocking member 232b functions to block dust from the airflow flowing upward from the cyclone 25. Specifically, the dust blocking member 232b includes a plurality of splitter plates. In the present embodiment, the number of the flow distribution plates 232b is four, which are uniformly circumferentially distributed around the axis of the filter part 232, i.e., the adjacent flow distribution plates 232b are perpendicular to each other. The function of the diverter plate of the dust guard 232b is to block dust while facilitating the flow of gas into the filter opening 232a.

The cup 21 is provided with a support structure 21a for supporting the filter cartridge 23. Specifically, a plurality of supporting protrusions 231a are circumferentially distributed on the annular supporting portion 231, and the supporting protrusions 231a radially extend outward from the circumference of the annular supporting portion 231.

As a further preferable mode of the above-described embodiment, a filter cotton 23a is provided between the filter element 23 and the air outlet 22a. The filter cotton 23a functions to adsorb fine dust remaining after being filtered through the filter 24 and the filter element 23. The filter cotton 23a can be installed on the cover 22, and also can be installed on the top of the filter element 23. In the preferred embodiment, the filter cotton 23a is mounted on the top of the filter element 23 by a compression block. The surface of the filter cotton 23a can prevent fine dust from entering the motor 4, the motor 4 is prevented from being damaged, and the filter cotton 23a is convenient to dismantle. Meanwhile, the filter cotton 23a is convenient to clean and can be used repeatedly.

The suction mechanism 3 communicates with the side of the cup body 21. The suction mechanism 3 is a suction nozzle, which is a prior art, and the specific shape and model can be selected according to specific situations, which is not described in detail in this embodiment.

The air circulation channel of the handheld dust collector is as follows: the gas enters the cup body 21 from the adsorption mechanism 3, then passes through the filter holes of the filter 24 into the interior of the filter 24, and then enters the cyclone 25 from the cyclone passage 251a. The gas forms a peripheral cyclonic flow within the cyclone 25, entrains the dust down the shroud 252, and then the gas moves up from the centre of the shroud 252 and into the filter element 23. The air moves from bottom to top in the filter element 23, passes through the filter cotton 23a, enters the motor and is finally discharged from the air outlet 12a of the machine shell 12.
