[0006] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: a dust suction nozzle, comprising a dust suction tube for detachable connection with a vacuum cleaner main body, the dust suction tube is sleeved with a brush sleeve that can slide back and forth along the axial direction, the brush sleeve is provided with bristles at one end facing the dust suction port of the dust suction tube, the inner circle of the brush sleeve is provided with a spring-lock mechanism, the dust suction tube is respectively provided with a spring-lock groove near the dust suction end and the middle section, the spring-lock groove is matched with the spring-lock mechanism, and the peripheral wall of the dust suction tube is also provided with a convex structure corresponding to the spring-lock groove one by one.

[0007] The preferred technical solution is: the snap mechanism includes a button, which is rotated in the brush sleeve through a rotating shaft, and a torsion spring is sleeved on the rotating shaft. The first force arm of the torsion spring is against the brush sleeve, and the second force arm of the torsion spring is against one side of the button. A hook is provided at the bottom of the other side of the button, and the hook remains extended out of the inner ring of the brush sleeve under the action of the torsion spring.

[0008] The preferred technical solution is: a limit strip for limiting the sliding range of the brush sleeve is also provided on the dust suction pipe.

[0009] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0010] The utility model proposes a dust nozzle, which realizes buckling and fixing between the brush cover and the dust collection tube by arranging a spring buckle mechanism on the brush cover and arranging a buckle groove corresponding to the spring buckle mechanism on the dust collection tube; in order to prevent the brush cover from shaking on the dust collection tube, a convex structure corresponding to the buckle groove is arranged on the dust collection tube, so as to achieve a tight fit when the brush cover is buckled with the dust collection tube.
