The embodiment is as follows: as shown in fig. 1 to 4, the present invention discloses a first embodiment of a hand-held cleaner having a primary filter member, which includes a body 100 having a suction port 120 and a handle 140, a dust cup 200 connected to the body 100, a primary filter member 300 disposed in the dust cup 200, a secondary filter member 400 located downstream of the primary filter member 300, a motor 500 located downstream of the secondary filter member 400, and a power source 600 for supplying power to the motor 500, wherein the suction port 120 extends in a direction passing through the motor 500.
The main body 100 further includes a dust cup receiving portion 160 located between the suction port 120 and the handle 140, a power source receiving portion 180 connecting the dust cup receiving portion 160 and both bottom ends of the handle 140, and a motor receiving portion 190 located at the top end of the handle 140 and receiving the motor 500 therein. The handle 140, the dirt cup receiving portion 160, the power source receiving portion 180, and the motor receiving portion 190 are integrally injection molded. The extending direction of the suction inlet 120 intersects the dust cup housing 160 at an acute angle. One end of the suction port 120 is connected to the suction nozzle, and the extension direction of the suction port 120 intersects the central axis direction of the motor 500 at an obtuse angle, which is greater than 90 degrees and smaller than 135 degrees. The extending direction of the suction inlet 120 intersects with the central axis direction of the dirt cup 200 at a non-right angle or a non-zero angle.
The dirt cup 200 is made of a transparent or translucent plastic material, and includes a cyclone chamber 220 at an upper end, a dirt chamber at a lower end, and a shield 240 located in the dirt chamber and adjacent to the cyclone chamber 220 to allow airflow therethrough. The cyclone chamber 220 is isolated from the dust chamber. The shroud 240 is centrally provided with a central aperture which allows airflow to pass through and into the cyclone chamber 220.
The primary filter 300 includes a mesh portion 320 having a cyclone air outlet 322 and a plurality of meshes 324, a ring portion 340 provided at a top end of the mesh portion 320, and a tubular portion 360 located inside the mesh portion 320 and communicating with the cyclone air outlet 322. Wherein the annular portion 340 has an air outlet 342 and a connector 344 disposed in the air outlet 342 at the top end of the tubular portion 360. In this embodiment, the air outlets 342 are two on two sides of the connecting piece 344, and the connecting piece 344 connects two opposite inner sides of the annular portion 340.
The secondary filter 400 is detachably mounted to the housing 100 in a direction corresponding to a central axis of the dirt cup 200. The secondary filter 400 is preferably a hypa or high density grade sponge and is located downstream of the mesh and upstream of the motor 500.
The power source 600 is a lithium battery or a nickel-metal hydride battery, and the arrangement direction of the batteries is parallel to the extending direction of the suction inlet 120, and a triangular supporting portion 620 is disposed at the bottom thereof.
