The working principle of the present invention is as follows:

Take the case where the body filter part has a two-stage cyclone filter structure, the handheld vacuum cleaner has a two-stage cyclone filter structure, and the whole machine has a total of four-stage filtration.

The air that has dust enters in the air duct 181 of the main body by the air inlet duct 31 of the handle bar 3, forms a spiral running track by the air duct of the main body and enters the dust cup 11 of the main body (①, ②, ③ in Fig. 2 ), the dust is thrown for the first time in the dust cup 11, and the dust is thrown to the inner wall of the dust cup 11 under the action of centrifugal force, and falls to the bottom of the dust cup along the inner wall of the dust cup. Large particles of dust, paper scraps, and hair are separated first, and after being filtered by the large body net cover 12, the first stage of dust and gas separation is completed.

The air with some fine ash enters the spiral wind impeller 142 through the large body mesh cover 12, and is guided by the spiral wind impeller 142 into the cyclone tube 141, and forms a spiral air intake track in the process of passing through the spiral wind impeller 142 , in the cyclone 141, part of the fine dust falls along the inner wall of the cyclone 141 into the second dust collecting space, completing the second stage of dust-gas separation.

Afterwards, the air with a small portion of fine dust enters the handheld vacuum cleaner through ④, ⑤, ⑥, ⑦. First, the dust and gas are separated through the filter screen cover 21, and the separated dust is collected in the third dust collection space 22, and the separated air enters the hand-held cyclone 231 through the hand-held spiral wind impeller 232 for separation again. The dust is basically separated and left in the fourth dust collection space 25 of the hand-held vacuum cleaner. The air with part of the fine dust passes through the cyclone cone 233 of the hand-held part upwards and enters the soft rubber sponge (not shown) through ⑧, and passes through the soft rubber sponge (not shown). The air filtered by the rubber sponge enters the motor to realize the complete separation of dust and gas.

The separation efficiency of the dust cup with a large body is more than 95%, which is obvious compared with other types of vacuum cleaners. improve. After four cyclones of dust and gas separation, Hypa is not easy to be blocked, which reduces the need for users to clean up Hypa. At the same time, the dust of large and small particles is divided into two dust cups, which is convenient for users to clean up. The structure of the large dust cup is simple and convenient for pouring dust.

In addition, the two helical wind impellers in the filter system are similar in structure. The helical wind impeller 142 is provided with a number of blades 1421 inclined downward, which can restrain the flow direction of the dust gas and swoop downward to form a spiral air flow.
