Abstract
The utility model discloses an absorbing nozzle of a dust collector, which comprises a body, an absorbing nozzle tube and a rotating brush arranged in the body, wherein the lower part of the body is provided with a main absorbing port; the top part of the body is provided with a top-surface absorbing port; the main absorbing port is communicated with the interior of the absorbing nozzle tube through a first passage; the top-surface absorbing port is communicated with the interior of the absorbing nozzle tube through a second passage; the absorbing nozzle also comprises a movable blockage selecting part; and the blockage selecting part is arranged between the body and the absorbing nozzle tube for blocking the first passage or the second passage so as to lead only one of the first passage and the second passage to be communicated with the interior of the absorbing nozzle tube at one time. The blockage selecting part selects one of the first passage and the second passage to be communicated with the absorbing nozzle tube, therefore, only one of the two passages is communicated with the absorbing nozzle tube, when dust is collected from the main absorbing port, the top-surface absorbing port is closed, and when dust is collected from the top-surface absorbing port, the main absorbing port is closed. The two absorbing ports can have adequate absorbing force when in work, thus improving the dust collecting effect.

Fig. 2 is the structural representation of the utility model cleaner suction nozzle state two;
Fig. 3 is the structural representation of the utility model cleaner suction nozzle state three.
[specific embodiment]
As Fig. 1,2, shown in 3, cleaner suction nozzle comprises body 3, suction nozzle pipe 6 and the revolution that is located in the body 3 brush 2, the bottom of described body 3 is provided with main suction inlet 1, the top is provided with end face suction inlet 4, described main suction inlet 1 communicates with suction nozzle pipe 6 inside by first path 7, end face suction inlet 4 communicates with suction nozzle pipe 6 inside by alternate path 8, also comprise and movably stop selection portion 9, the described selection portion 9 that stops is arranged on the front portion of suction nozzle pipe 6, first path 7 or alternate path 8 are stopped, make first path 7 and alternate path 8 synchronizations that one and suction nozzle pipe 6 internal communication can only be arranged.The described selection portion 9 that stops is arranged on the front portion of suction nozzle pipe 6, and is stopping that selection portion 9 has pipe suction inlet 5, and the described selection portion 9 that stops can move with suction nozzle pipe 6, and pipe suction inlet 5 stops that selection portion 9 stops alternate path 8 when being communicated with first path 7; When pipe suction inlet 5 is communicated with alternate path 8, stop that selection portion 9 stops first path 7.
The described bottom of selection portion 9 that stops is provided with lower convexity 10, and body 3 bottoms are provided with lower limit portion 12, and the inwall of described lower limit portion 12 is close to the outer wall that stops selection portion 9.Be close to and can guarantee sealing property, lower convexity 10 cooperates with lower limit portion 12 to form and stops, carries out rotary spacing.The described top that stops selection portion 9 is provided with projection 11, and body 3 tops are provided with upper limit portion 13, and the inwall of described upper limit portion 13 is close to the outer wall that stops selection portion 9.Be close to and can guarantee sealing property, last projection 11 cooperates formation to stop with upper limit portion 13, carries out rotary spacing.The end of upper limit portion 13 and lower limit portion 12 is equipped with sealed muscle 14.Further improve sealing property.The cross-sectional area of described first path 7 and alternate path 8 is all less than the cross-sectional area of managing suction inlet 5.Like this, the space of first path 7 and alternate path 8 can make full use of, and avoids the waste in space.
Fig. 1 is the maximum angle schematic diagram of common user mode (by main suction inlet 1 dust suction), and when clearing away usually on ground, at first rubbish sucks from main suction inlet 1, by first path 7 and pipe suction inlet 5 and the suction nozzle pipe 6 inner air flues that form, is sucked by dust catcher.At this moment alternate path 8 is an air-tight state, and the 4 not dust suctions of end face suction inlet have guaranteed that main suction inlet 1 has sufficient suction, has improved pick-up performance.
Fig. 2 is the minimum angles schematic diagram of common user mode (by main suction inlet 1 dust suction), under Fig. 1 state, constantly press down suction nozzle pipe 6 and push up ground up to the bottom of suction nozzle pipe 6, the opening of the pipe suction inlet 5 and first path 7 produces relative displacement in this process, but, because the cross-sectional area of pipe suction inlet 5 is greater than the cross-sectional area of first path 7, so still can guarantee to manage being communicated with of suction inlet 5 and first path 7, and, make full use of the space of first path 7, guaranteed the good result of use of main suction inlet 1 dust suction state.Under this state, rubbish sucks from main suction inlet 1, by first path 7 and pipe suction inlet 5 and the suction nozzle pipe 6 inner air flues that form, is sucked by dust catcher.At this moment alternate path 8 is an air-tight state, and the 4 not dust suctions of end face suction inlet have guaranteed that main suction inlet 1 has sufficient suction, has improved pick-up performance.
Fig. 3 is the schematic diagram of end face user mode (by 4 dust suctions of end face suction inlet), when end face such as at the bottom of the bed is cleared away, suction nozzle pipe 6 is mentioned, under the gravity effect, body 3 front portions of suction nozzle rotate, and push up lower convexity 10 formation up to lower limit portion 12 and stop, this moment, alternate path 8 was communicated with pipe suction inlet 5, rubbish sucks from end face suction inlet 4, forms air flue by alternate path 8 and pipe suction inlet 5, is sucked by body of dust collector 3.At this moment first path 7 is an air-tight state, and main suction inlet 1 not dust suction has guaranteed that end face suction inlet 4 has sufficient suction, has improved pick-up performance.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
