Multifunctional garbage separating device

The invention discloses a multifunctional garbage separating device. The multifunctional garbage separating device consists of a shaking table, a stepless speed regulating system, a material feeding groove and a water feeding groove, wherein the shaking table repeatedly moves under the action of the stepless speed regulating system; the moving frequency and the fluctuation amplitude of the shaking table are regulated and controlled by the stepless speed regulating system; garbage is dispersed to a bed surface from the material feeding groove under the movement of the shaking table and is mixed with water from the water feeding groove, and since the bed surface structure of the shaking table is that the horizontal surface of the rear end of the shaking table is higher than the front end of the shaking table, the garbage moves to the front end of the bed surface under the driving of water flow, when the garbage and the water flow through a wave-shaped flowing groove in the bed surface in ...

Hair care device

A hair care device (10, fig.1) comprising an airflow mover 29 for moving air through a passage 27 from an inlet 11 to an outlet 12, and an opening (35, fig.4), preferably upstream of the air mover, fluidly connecting the passage with an electronics cavity 31 housing an electronic component 32, such as a PCB, battery, or ioniser. The opening may have an air permeable barrier that restricts passage of water, preferably with a mesh (42, fig.4) and a hydrophobic coating. An air heater 30 may be in the passage downstream of the opening. The electronics cavity may be in an annular space between a main body (18, fig.2) defining the passage, and a surrounding housing 19 that forms a handle (13, fig.1). A sealing member (37, fig.4) may be provided with a first portion (38, fig.5), which may include an aperture (39, fig.5) and skirt (44, fig.5), sealing between the main body and housing, and a second portion (40, fig.5), which may include an aperture (41, fig.5) and tab (45, fig.5), sealing about the opening.
