The rear of the body 11 is electrically connected to a battery pack 21, the battery pack 21 is used to supply power to the motor assembly 20, and the motor assembly 20 generates a dust suction airflow when rotating at a high speed to suck air and dust into the dust bucket unit 23. The body 11 also includes a handle 14, the handle 14 being easily grasped by a user for performing a dust-cleaning operation.
And a dust bucket unit 23 connected to the body 11 for filtering and containing dust. The dust bucket unit 23 and the body 11 may be locked or may be provided in a detachable manner. The dirt cup unit 23 includes a dirt cup 12, a dirt cup lid 15, a main suction pipe 13, a cyclone cone assembly 16, and a latch mechanism 22.
The dirt cup 12 is provided at the periphery of the dirt cup unit 23 for receiving dirt and also for receiving and supporting other components inside. A main suction pipe 13 is arranged in front of the dust cup 12. The main suction pipe 13 has one end connected to the dust cup 12 and the other end connected to the conductive pipe 29 for guiding a suction airflow from the suction nozzle 30 into the dust bucket unit 23. The bottom of the dust cup 12 is provided with a dust cup cover 15 which is connected with the dust cup 12 in an openable manner, so that dust in the dust cup 12 can be poured conveniently. In this embodiment, the dust cup 12 and the body 11 are detachably connected by a snap.
The interior of the dirt cup 12 is provided with a cyclone cone assembly 16. The air path inside and outside the cyclone cone assembly 16 is circuitous, and the dust-collecting airflow is rotated at a high speed when passing through the air path, and due to the centrifugal action, the dust in the dust-collecting airflow is thrown out of the air at a high speed and separated from the clean air, so that the dust falls into the bottom of the dust cup 12, and the clean air flows to the motor assembly 20. This cyclone dust and air separating structure is well known in the art of vacuum cleaners and will be briefly described.
The cyclone cone assembly 16 includes a screen assembly 28, a cyclone cone 17, and an inlet air filter 18. The top of cyclone cone 17 is provided with a mounting part 19, and the air inlet filter piece 18 is placed in the mounting part 19 and can be taken out of the mounting part 19 for cleaning or replacement. The cyclone cone 17 is assembled inside the screen assembly 28 by friction fit, the top of the cyclone cone 17 is higher than the top of the screen assembly 28, and the cyclone cone 17 can also be pulled out of the screen assembly 28, after cleaning, the cyclone cone 17 can be reloaded into the screen assembly 28, and the tight fit is realized by friction.
Fig. 4 is a partial cross-sectional view of a dirt cup unit in an embodiment of the present invention; and fig. 5 is an enlarged view of a portion of a locking mechanism in an embodiment of the present invention.
As shown in fig. 4 and 5, the locking and unlocking mechanism 22 includes a guide groove 24, a spigot 25 and a boss 26. The top of the dust cup 12 is provided with a circular hole, and the inner wall of the circular hole is provided with four salient points 26. Four guide slots 24 are provided in the top of the screen assembly 28, and each guide slot 24 terminates in a spigot 25 which mates with a nub 26 on the inner wall of the circular aperture of the dirt cup 12.
A flow guide tube 27 is arranged below the filter screen assembly 28, and a user can hold the flow guide tube 27 to operate the cyclone cone assembly 28. When a user holds the honeycomb duct 28, the cyclone cone assembly 28 moves upwards from the lower part of the dust cup 12 until the top of the cyclone cone assembly 16 touches the inner wall of the top round hole of the dust cup 12, at the moment, the user rotates the cyclone cone assembly 16 in the anticlockwise direction, the four guide grooves 24 can respectively find the four salient points 26, each salient point 26 rotates to the spigot 25 along the guide groove and is in friction fit with the spigot, and the cyclone cone assembly 16 is fixed inside the dust cup 12. When the cyclone cone assembly 16 is secured within the dirt cup 12, a user may grasp the draft tube 28 and rotate it clockwise to release the cyclone cone assembly 16 from the dirt cup 12 and remove it from the opening below the dirt cup 12, and may further remove the inlet filter member 18 from the mounting portion 19 at the top of the cyclone cone assembly 16 to clean or replace the inlet filter member 18.
After the suction airflow enters the main suction pipe 13, the suction airflow rotates counterclockwise around the filter screen assembly 28 to further tightly fit the spigot 25 with the salient point 26. The dust is thrown from the air and falls to the bottom along the inner wall of the dirt cup 12, the air passes through the screen of the screen assembly 28 into the cyclone cone 17, the dust entrained in the air is further separated from the air by centrifugal separation, the dust falls along the duct 28 to the bottom of the dirt cup 12, and the air passes through the air intake filter 18, wherein the cyclone structure is well known in the art of vacuum cleaners and will not be described in detail herein.
