Description
Technical field
The present invention relates to a kind of bathroom accessory, more particularly, relate to a kind of flexible scavenge pipe of two motion.
Background technology
The cleaning device of existing intelligent closestool, conventional implementation:
1, utilize hydraulic cylinder principle control single tube or two-tube scavenge pipe to stretch, realize the cleaning to buttocks and secret place.
2, utilize the mechanisms such as gear, steel band, Timing Belt, screw rod that the scavenge pipe of single tube or two-tube (up and down or left and right side by side) is stretched, realize the cleaning to buttocks and secret place.The cleaning drying device that Chinese invention patent 201220232234 discloses a kind of toilet comprises: a cleaning device, and it comprises the cleaning arc-shaped guide rail, that a relative toilet fixes and is connected to the cleaning body of the arc of cleaning arc-shaped guide rail, at least one hose, one first transmission mechanism and a cleaning power unit; Described hose leading portion is installed in cleaning body, and rear end is installed in watering; The arc of described cleaning arc-shaped guide rail is suitable with the arc of cleaning body; Described cleaning power unit is cleaned body by the first transmission mechanism connection and cleaning body can be driven relatively to clean arc-shaped guide rail and arcuately stretches; And a drying unit, it comprise oven dry arc-shaped guide rail, that a relative toilet fixes be slidably connected at the arc of drying arc-shaped guide rail oven dry body, a hot blast produces mechanism, one second transmission mechanism and dries power unit; Described hot blast produces the slip of device front end mouth and puts in oven dry body; The arc of described oven dry arc-shaped guide rail is suitable with the arc of drying body; Described oven dry power unit is dried body by the second transmission mechanism connection and oven dry body can be driven relatively to dry arc-shaped guide rail and arcuately stretches.In conjunction with described in the Figure of description of invention, can find out, thus disclosure of the invention be utilize gear set drive to clean arc-shaped guide rail, thus drive cleaning dress body to move back and forth.
Two kinds of above-mentioned motion modes are all generally front-rear reciprocation movements in a linear fashion, and the direction of motion and ceramic water plane are 30 ° ~ 50 ° angles.Utilize the telescoping tube that hydraulic cylinder principle controls, due to structural restriction, larger to outward appearance restriction.Scavenge pipe major part is single-unit pipe, and minority is binodal or more piece pipe.The scavenge pipe of single-unit pipe, because the length of cleaning device must ensure, must ensure extension elongation, thus the overall length of restriction split toilet, limit the suitability of split toilet.Though the scavenge pipe of binodal or more piece pipe can reduce length, but less stable, and outward appearance and manufacturability are also poor.
