Abstract
The utility model discloses a liquid level switch with liquid level indicator for a micro-ultrasound atomizer, which comprises a housing, a circuit board and a buoy capable of rising and falling up and down, wherein the buoy is arranged at the upper end of the housing; a conductive body which can move up and down to control the disconnection or connection of the circuit board under the action of the magnetic force between the buoy and the conductive body is arranged between the buoy and the circuit board. The utility model do not use electron devices to carry out control, thereby, has the advantages of low cost and simple manufacture and assembly to completely overcome defects of the existing atomizer switch. Therefore, the operation of the atomizer is more safe and reliable, and the utility model can effectively give full play to optimum atomization effect. As atomization slices are not easy to burn, the utility model has long service life. Besides, with the adoption of the technique of buoy indication, the utility model is more visual, convenient and accurate for observing liquid level and charging liquid. The utility model is suitable for various electronic ultrasound atomizers with different power and different appearances.
Description
Technical field
The utility model relates to a kind of miniature ultrasonic atomizer, particularly a kind of atomizer switching device with the liquid level indication.
Background technology
Phenomenons such as electric field violate-action couple corrosion appears, in " electrode touches ability of swimming ", " electric field induction " switching mode easily that be used for atomizer at present.Someone has invented a kind of " adopting the miniature ultrasonic atomizer of magnetic inducted level switch " (Chinese patent 02271748.X), though overcome the drawback of aforementioned switches, but still there is serious defective in actual applications: under exsiccosis, the inclination of atomizer, upset, inversion can make float slide in cavity, can start atomizer work equally, cause atomizing piece to burn out.And, the best atomizing effect of miniature ultrasonic atomizer is between atomizing piece is apart from liquid level 20-50mm, existing miniature atomizer but is difficult to hold the amount and the best liquid level of liquid filling when reality is used, long-term use is very inconvenient, the improper atomizing effect that also can directly influence atomizer of liquid level.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of simple and convenient, and is not fragile, can control the miniature ultrasonic atomizer liquid-level switch of the band liquid level indication of atomizer start and stop according to water level automatically.
The purpose of this utility model is achieved in that a kind of miniature ultrasonic atomizer liquid-level switch with the liquid level indication, comprise shell, circuit board and be located at the floating drum that shell upper end can upper and lower lifting, it is characterized in that: but be provided with in the middle of described floating drum and the circuit board nationality by and floating drum between upper and lower the moving of magnetic force and control circuit board disconnects or the electric conductor of conducting.
Described electric conductor places in the guide, and position relative with floating drum on the circuit board is provided with conductive via, and the unidirectional opening of this guide props up circuit board and is positioned at the conductive via top.
The utility model does not use electronic device control, cost is low, it is simple to make assembling, overcome the deficiency of existing atomizer switch fully, made the work safety and reliability of atomizer, can effectively bring into play the best atomizing effect of atomizer, atomizing piece all is difficult for burning under any state, longer service life, and adopted " buoy " indication technology, make observation liquid level and filling liquid more directly perceived, convenient, accurate.The utility model is applicable to the electronic ultrasonic atomizer of various different capacities, different profiles.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is by shell 1, floating drum 2, compositions such as electric conductor 4, circuit board 8.In the cavity of floating drum 2 monolithic cases 1, can float with liquid level is upper and lower, floating drum 2 tops are provided with colored arrow shaped colour code 3, and the bottom is provided with iron plate 6 or magnetic steel plate.Circuit board 8 is located in the shell 1, and its position corresponding to floating drum 2 is provided with a band tin conductive via 7, and diameter is slightly less than electric conductor 4, can when printed circuit board, make, to cut off in the middle of the copper clad plate on 7 of the via holes, with the input 10 of power supply link to each other on one side, another side links to each other with load 11.Between floating drum 2 and circuit board 8, be provided with electric conductor 4, make shapes such as sphere, cylindricality by magnetic or nonmagnetic material (as iron).Electric conductor 4 or floating drum 2 bottoms one of at least have magnetic among both, thereby can attract each other by magnetic force.Electric conductor 4 places in the guide 5.The end face 9 that guide 5 parts are pierced atomizer is fixed on the outer cover of atomizer 1, and the unidirectional opening of guide 5 is tight against on the conductive via 7 of circuit board 8, and electric conductor 4 can make via hole 7 two ends conductings when embedding via hole 7.
When floating drum 2 dropped to the bottom, electric conductor 4 was owing to the breaking circuit plate 8 with iron plate 6 adhesives of floating drum 2 bottom surfaces, and the complete machine power supply disconnects; When floating drum 2 rose, because buoyancy and the effect of gravity and the restriction of guide 5, magnetic force weakened gradually between electric conductor 4 and the iron plate 6, comes off at last to embed in the via hole 7 power turn-on again; Canting when the charged lack of water of atomizer, upset, inversion, electric conductor 4 hightail circuit board 8 and tightly adhesive of floating drum 2, and power supply is disconnected.The colour code 3 on floating drum 2 tops is the red arrow shape, when liquid level is lower than red arrow, is the best atomizing lower limit liquid level, and prompting needs filling liquid; When the filling liquid level floods red arrow, be the best atomizing upper limit liquid level, prompting stops the liquid of annotating.
