Problems solved by technology
[0003] 1. The suction cup of the existing vacuum head is often set on a plane, the suction force in the middle of the suction hole is large, the suction force on both sides is small, and the suction force is unevenly distributed, resulting in the dust far away from the middle suction hole cannot be sucked clean, and the efficiency is low
[0004] 2. There are no deflector fins on both sides of the suction cup of the existing suction head, and the dust particles directly collide with the top of the suction hole flow channel, causing a large amount of impact loss

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings:
[0021] Such as figure 1 As shown, the present invention provides a fin-adjustable vacuum cleaner head, comprising a suction cup 1 and an elbow 8 arranged on the suction cup 1. The suction cup 1 is provided with a suction hole channel 2 in the middle, and a plurality of suction cups are provided on both sides of the suction cup 1. The fin 4 is provided with a dust suction port 6 in the middle of the suction hole channel 2, and the dust suction port 6 communicates with the channel in the elbow 8. The fins 4 on both sides of the suction hole channel 2 are arranged in a staggered manner. The elbow 8 is connected with the vacuum cleaner.
[0022] Preferably, the fins 4 are arranged from dense to sparse from the dust suction port 6 to the edge of the suction cup 1 in sequence. The suction head is provided with inclined fins with unequal widths and intervals on both si...

The invention discloses a fin adjustment type dust collection head. The fin adjustment type dust collection head comprises a suction cup and a bent pipe arranged on the suction cup. A suction hole passageway is formed in the middle of the suction cup. A plurality of fins are arranged on the two sides of the suction cup. A dust collection opening is formed in the middle of the suction hole passageway and communicated with a passageway in the bent pipe. Inclined toothed plates of equal widths and equal intervals are arranged on the two sides of the suction cup of the dust collection head. The resistance distribution and flow direction of a dust collection passageway can be regulated when gas enters the dust collection passageway, and therefore the dust collection efficiency of the dust collection head is improved, the striking loss is reduced, and the effect of rapidly and efficiently sucking dust of floors and carpets is achieved.
Description
Technical field [0001] The invention relates to the field of vacuum cleaner accessories, in particular to a dust suction head device. Background technique [0002] The vacuum cleaners currently in use are equipped with a rectangular flat suction cup with suction holes at the lower end of the suction pipe, and the dust is sucked away through the middle suction hole. Therefore, the traditional suction cups often appear near the center of the suction hole and the dust is easy to clean. The dust on both sides of the suction cup is difficult to clean. In short, the existing vacuum cleaner head device has the following disadvantages: [0003] 1. The suction cup of the existing vacuum cleaner head is often set on a flat surface, the suction force in the middle of the suction hole is large, and the suction force on both sides is small, and the suction force is unevenly distributed, which causes the dust far away from the middle suction hole to be unable to be cleaned and the efficiency is...
