The mini ultrasonic atomizer comprises a shell, an energy conversion plate, a breadboard part and the magnetic inductive liquid level switch. Wherein the breadboard part is enclosed in the shell; the energy conversion plate is arranged on a concave position of the shell through a rubber obturating ring and a chuck ring, the underside of the energy conversion plate is pressed a metal spring, and the lower end of the metal spring is connected with the output of an ultrasonic oscillator on the breadboard; the magnetic inductive liquid level switch adopts the reed switch type magnetic inductive liquid level switch and is vertically arranged on the top of the shell; and a magnetic float which lifts or falls along with the liquid level can force the reed switch to be on or off for controlling the mini ultrasonic atomizer to be started or stopped. The utility model has the advantages of novel design, small size, high working sensitivity, high reliability, low energy consumption and long service life.
Description
Technical field
The utility model relates to the miniature ultrasonic atomizer, particularly a kind of miniature ultrasonic atomizer that adopts magnetic inducted level switch.
Background technology
The liquid level control switch of existing ultrasonic atomizer adopts dual mode mostly: 1. electrode touches ability of swimming, 2. electric field induction.But the atomizer of taking above-mentioned two kinds of control modes all exists shortcoming separately, adopt electrode to touch the atomizer of ability of swimming liquid level control switch, when work, the transducing sector-meeting is produced couple corrosion, to cause the transducing sheet lost of life, and electrode is when being immersed in the liquid for a long time, electrode contact can deposit dirt, causes reducing the sensitivity and the functional reliability of switch.The atomizer that adopts the electric field induction liquid level control switch is when work, its couple corrosion situation makes moderate progress, but can not avoid fully, and it is not enough at water level, switch cuts out, still have an appointment when atomizer quits work 20MA by operating current, thereby cause energy consumption to increase and slight couple corrosion, reduce the service life of transducing sheet, in addition, when staff or other object touch inductive switch, can cause atomizer work, cause atomizing piece to burn out.
Summary of the invention
Order of the present utility model ground is exactly to have the ultrasonic atomizer above shortcomings now for overcoming, and provides a kind of easy to use, and energy consumption is little, functional reliability, the miniature ultrasonic atomizer that the life-span is long.
The miniature ultrasonic atomizer of this employing magnetic inducted level switch, comprise: shell, the transducing sheet, wiring board part and liquid-level switch, the embedding of wiring board part in the enclosure, the transducing sheet is installed in recess on the shell by rubber seal and pressure ring, push down metal spring below the transducing sheet, the spring lower end is connected to the output of wiring board ultrasonic vibrator, and its liquid-level switch adopts magnetic inducted level switch, and magnetic inducted level switch is erect and is installed in above the shell.Adopt the dry-reed magnetic inducted level switch in the exemplary embodiments, can make tongue tube closed or disconnect the start and stop of control atomizer with the magnetic float of liquid level lifting.
The utlity model has following advantage compared with the prior art:
Its compact conformation, volume is little, and cost is low, adopts new magnetic inducted level switch, has stopped the couple corrosion phenomenon that conventional atomizers exists fully, and the life-span is long.
When atomizer quit work, conventional atomizers remained at the about operating current of 20MA, and the utility model atomizer does not have any operating current when quitting work, thereby had saved energy consumption, had avoided the couple corrosion that the faint electrolysis of water is caused.
Because adopt magnetic inducted level switch to adopt vertical structure, the distance between the magnetic float of liquid-level switch and the transducing sheet can be turned down as far as possible, make atomizer possess lower priming level and reach by working water level.
This miniature atomizer process reaches six months test, test, and the result of use ideal, highly sensitive, working stability is reliable, and is easy to use.
Description of drawings
Fig. 1 is the typical structure schematic diagram of this miniature ultrasonic atomizer;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Further specify below in conjunction with the embodiment accompanying drawing.
As shown in Figure 1, 2, this miniature ultrasonic atomizer mainly comprises: shell (1), transducing sheet (2), wiring board (5), power line (9), bottom (11), LED light (12) and magnetic inducted level switch (6) etc.
Wherein magnetic inducted level switch (6) is in reed pipe formula magnetic inducted level switch.Wiring board (5), transducing sheet (2), LED light (12), liquid-level switch (6) etc. all is assembled into an integral body.
Shell is offered a plurality of apertures on (1), power line (9), indicator lamp (12), liquid-level switch (6) is directly erect and is installed on the metal shell (1), and transducing sheet (2) is positioned at the recess of shell, and pad is gone up rubber seal (3) as cutting off between transducing sheet (2) and the shell (1), the outside uses pressure ring (10) to compress again, pressure ring (10) is connected by threaded engagement with shell (1), and two gap are arranged on the pressure ring (10), screws or screws out by gap is stressed.Push down metal spring (4) below the transducing sheet (2), the spring other end is wired to the output that wiring board (5) is gone up ultrasonic vibrator, and wiring board (5) is packaged in the inner chamber of metal shell (1) with bottom (11), the epoxy resin embedding of whole inner chamber.
The dry-reed magnetic inducted level switch of this atomizer is made up of tongue tube (7), magnetic float (8) and housing, tongue tube (7) is packaged in the housing and fixes with casing, can move up and down along housing with the magnetic float (8) of liquid level lifting to make tongue tube closed or disconnect.
Two adjacent cavitys are arranged in Fig. 1 middle shell, and tongue tube is packaged in the cavity of housing, and magnetic float places in another cavity with holes of housing, and tongue tube and magnetic float be arranged in parallel about being.Tongue tube can be taked vertical up and down set-up mode with magnetic float.When adopting the magnetic float of annular, the magnetic float of annular is sleeved on upright tongue tube outside.Above-mentioned several set-up modes of tongue tube and magnetic float all can obtain extremely stable and sensitive effect.
When liquid level exceeds the transducing sheet, when reaching a certain height, magnetic float moves up, and makes reed switch conduction, atomizer startup work.When liquid level dropped to critical groundwater table, magnetic float descended, and tongue tube disconnects, and atomizer quits work.
Because magnetic inducted level switch adopts vertical structure, the distance between the magnetic float of liquid-level switch and the transducing sheet can be turned down as far as possible, makes atomizer possess lower priming level and reaches by working water level.
The circuit part of miniature ultrasonic atomizer is with traditional circuit, by power transformer, rectification circuit, and sonic oscillation circuit, formations such as magnetic inducted level switch control circuit.Rectification circuit is respectively by power line and transformer, the sonic oscillation circuit, the magnetic induction switch control circuit is electrically connected, the sonic oscillation circuit is connected with transducing sheet, indicator lamp by the sonic oscillation output line respectively, and the magnetic inducted level switch control circuit is electrically connected with magnetic induction fluid level controller and supersonic oscillations circuit mutually by magnetic induction output line and switch controlling signal output line respectively.
The employing of dry-reed magnetic inducted level switch, the couple corrosion phenomenon of having avoided conventional atomizers to exist fully, easy to use, reliable operation, the life-span is long.
