Abstract

A pocket-type ultrasonic atomizer structure comprised of a water reservoir, an atomization chamber and an atomizing unit of a main unit, and a water supply regulating mechanism, wherein the opening and closing of the water supply regulating mechanism and the water reservoir is integrated such that closing the water reservoir enables the simultaneous entry of a volume of water required in the atomization chamber through atmospheric pressure and the maintenance of a preset liquid surface height to thereby achieve low-voltage atomizing performance.

Claims

1. An ultrasonic atomizer structure comprising:

a main unit, a water supply regulating mechanism, and an atomizing unit, said main unit including a bottom cover, a middle casing, and an upper casing assembled into a vertical body;

said bottom cover secured onto an underside of said middle casing;

said middle casing including a compartment into which a fan is installed, a hollow ventilator duct and a hollow pipe extending vertically from a top side of said middle casing, a water input hole formed in said pipe near a bottom end of said pipe and a connective channel disposed between said pipe and said ventilator duct;

said upper casing hermetically conjoined to a top section of said middle casing, a sealed interior section formed between said upper casing and said middle casing to form a water reservoir, a filler opening for adding water, a pivot hole, and an output port for diffusing atomized particles respectively disposed on a top side of said upper casing, a mist tube movably sleeved onto a mouth of said output port;

said water supply regulating mechanism comprising a valve controlling stem which is an active tubular component installed inside said middle casing hollow pipe, having a valve on a bottom end that is aligned with an inner diameter of said pipe and an adjustment knob at a top end, said adjustment knob being utilized to rotate said valve controlling stem within a range of preset angles, thereby synchronously controlling said valve to open or close said water input hole at an inner wall of said pipe;

a pressure cover frictionally fitted into said upper casing filler opening and secured in place by a check section projecting from said adjustment knob that exerts downward pressure against a top side of said upper casing;

said atomizing unit comprising an accumulator, an elastic sleeve, a vibrator element, a conductive ring, and a circuit board, said accumulator disposed at a lower extent of said upper casing ventilator duct within the sealed interior section of an atomization chamber which has a conical space at its bottom end, an orifice through a center of said conical space, an annular groove section of a tapered contour formed around said orifice, a coupling ring placed around said annular groove section, and a circular wall extending outward axially and concentrically from an outer circumference of said coupling ring;

said elastic sleeve being a soft insulation fitting having an inner conical section for aligned insertion into said conical space of said accumulator, an annular shoulder section of a stepped profile contoured downward along an inner diameter of said conical section that produces a constricted passage of a very small diameter at a bottom side of said orifice, a round hole that is aligned with said accumulator orifice, an annular edge extending downward from an outer diameter of said elastic sleeve, and an enclosing space receding towards its interior section;

said vibrator element inserted flat into said elastic sleeve enclosing space and being capable of generating a sonic field sufficient to efficiently atomize liquid from said water reservoir;

said conductive ring being a thin annular component dimensioned to fit into said enclosing space having an end surface firmly attached to a bottom side of said vibrator element; and

said circuit board being an electronic control circuit tightly fastened to said accumulator within an interior section of said middle casing compartment.

2. The ultrasonic atomizer structure as claimed in claim 1, wherein said bottom cover has two L-shaped projections each extending in parallel with its bottom side for assembly onto a mounting base underneath;

said mounting base being a substructure that matches a shape of said bottom cover consisting of a constraining wall extending along its peripheral edge, a pair of inverted L-shaped protrusions on its end surface that corresponds in reverse to positions of said L-shaped projections at a bottom side of said bottom cover and which provides for their parallel slip insertion into said L-shaped projections, and an elastic clip at a center section of its front side that is divided into two lateral aspects capable of upward and downward flexure, with a pawl section at a top side of said elastic clip extending upward to engage a lip at the bottom side of said bottom cover to prevent backing off and dislodging from said main unit;

a bottom side of said mounting base is then secured in an interior of the vehicle.

3. The ultrasonic atomizer structure as claimed in claim 1, wherein said bottom cover has two L-shaped projections each extending in parallel with its bottom side for assembly onto a battery base underneath;

said battery base being a substructure that matches a shape of said bottom cover consisting of a constraining wall extending along a peripheral edge of said bottom cover, a pair of inverted L-shaped protrusions on its end surface that corresponds in reverse to positions of said L-shaped projections at a bottom side of said bottom cover and which provides a parallel slip insertion into said L-shaped projections, a the center section of a front side of an elastic clip divided into two lateral aspects capable of upward and downward flexure, with a pawl section at a top side of the elastic clip extending upward to engage a lip at the bottom side of said bottom cover to prevent backing off and dislodging from said main unit, power terminals projecting from its top surface that mechanically contacts power terminals of said main unit to establish electrical continuity with batteries.
