Such as Fig. 2 ~ shown in Figure 4, described left and right pin 370,371 is connected to described left and right sides cantilever 311,312 and described support 350 on the described left and right flanges 331,332.As shown in Figure 2, described left and right pin 370,371 comprise can be successively slotted hole 313 rear interconnective cylindric latch 370a, 371a and circular plug 370b, 371b by described left and right flanges 331,332 through hole 334, the through hole 358 of described lower bracket 355, described left and right sides cantilever 311,312.
Because described left and right pin 370,371 determines that by the described anterior position that is located at described left and right sides cantilever 311,312 inboards convex closure 314 and described rear position determine that convex closure 315 is exerted pressure respectively, with when cantilever 311,312 forward and backward the sliding of the described left and right sides, make described left and right sides cantilever 311,312 that strains occur.Therefore, determine described left and right pin 370,371 size and material with this.
As mentioned above, left and right sides cantilever 310 plays the front and back gliding member function that slide front and back according to the structure of slotted hole 313 and linear guiding device 333.Therefore, be convenient for changing cleaning pad, and can according to the thickness of cleaning pad, keep certain ground and 163 spacings of nozzle suction inlet, to obtain equal suction.Because spacing is long, can reduces suction, and then reduce dust collection efficiency; And spacing is too short, then can adsorb on the ground, transfers before and after causing being difficult to.
Described joint is located on the eccentric e position of position between the center c of the front end of described mophead 110 and described mophead 110, why described joint 300 keeps such position, be because in the structural element of described joint 300, described left and right flanges 331,332 is on position between the center of the front end of described mophead 110 and described mophead 110.As shown in Figure 3, by described left and right flanges 331,332 eccentric position, be used for connecting described left and right sides cantilever 311,312 and described support 350 and described left and right flanges 331,332 described left and right pin 370,371 position, will be from the center c position deviation e distance of described mophead 110.
Accordingly, can effectively prevent the phenomenon that leans forward at the weight center that causes because of the weight that is located at the shower nozzle suction nozzle 160 on described mophead 110 anterior position, the phenomenon that mophead lifts when rotating described shell 200 to alleviate in front and back.
In addition, adopt the structure that directly supplies water to cleaning pad by described water supply installation 140, with the cleaning pad of wet rag as vacuum cleaner.At this moment, because the frictional force between wet rag and the ground is excessive, therefore when dropping vacuum cleaner backward, the possibility that lift in the place ahead of dust catcher also can increase, but if eccentric structure just can be contained this phenomenon of lifting to greatest extent.
In advance statement, the technology of the present invention is not limited to a described specific preferred embodiment, as long as under the prerequisite that does not break away from the main idea of the present invention of applying in the application range, the people who has the common sex knowledge of the technical field of the invention, all can carry out various deformation, and such change belongs to all in the application range of the present invention.
