Description

Ultrasonic atomization transducing sheet

Technical field

The utility model ultrasonic atomization transducing sheet belongs to the supersonic atomizer field, particularly relates to the low-power used on a kind of ultrasonic ultrasonic delay line memory or the ultrasonic atomization transducing sheet of low-voltage.

Background technology

Be used for humidification, perfuming, sterilization or ornamental supersonic atomizer in the daily life, the ultrasonic wave that the liquid that is contained in the liquid container can be produced by supersonic generator is the atomization of liquid, thereby realizes its atomizing functions.Ultrasonic atomization transducing sheet comprises by the drive circuit of electrode and auto-excitation type to be formed, the back side at ultrasonic atomization transducing sheet is provided with electrode coating, the electrode coating area at the back side of traditional ultrasonic atomization transducing sheet is all greater than 78 square millimeters, its operating frequency is generally more than the 1.7MHZ. in these atomising devices, the general voltage that all needs to use more than the 24V, power all is useful on lower powered recessed chip transducing sheet now greater than 5W., the cost height, and efficient is low.Be useful on lower powered pore type transducing sheet now, atomizing particle is big, loses efficacy thereby blocked the hole by the particulate in the water easily, and service life is extremely short, and the application scenario is restricted, and its drive circuit generally adopts separately driven circuit, and operating frequency is about 100KHZ.

Summary of the invention

The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of cost low, and atomization quantity and efficient height are applicable to the ultrasonic atomization transducing sheet of the occasion of low-voltage and low-power consumption.

The purpose of this utility model reaches by following measure, ultrasonic atomization transducing sheet comprises by electrode and drive circuit to be formed, the back side at ultrasonic atomization transducing sheet is provided with electrode coating, drive circuit comprises by metal-oxide-semiconductor, inductance L 1 and inductance L 2 and forming, the area of the electrode coating at the ultrasonic atomization transducing sheet back side is less than 40 square millimeters, the transducing sheet links to each other with inductance L 2, the switch drive inductance L 1 of metal-oxide-semiconductor, and inductance L 1 is mutual inductance with inductance L 2.

Through experimental studies have found that, the size of the atomization quantity of ultrasonic atomization transducing sheet and backplate coating area and relevant, the electrode coating at the back side is meant that electrode coating that does not contact water, the electrode coating area is narrowed down to below 40 square millimeters, under condition with constant power, being added in power on the unit are will increase and be twice, atomization quantity is relevant with added power on the unit are, will not having mist when added power is lower than a certain value on the unit are produces, therefore adopt and dwindle ultrasonic atomization transducing sheet backplate coating area, play the effect of cumulative, the occasion of low-voltage particularly, as 5V and 12V etc., be applied to lower powered occasion, mist amount and efficient improve obviously.Drive circuit is the separate excitation drive circuit, and by the switch drive inductance L 1 of metal-oxide-semiconductor, inductance L 1 is mutual inductance with L2, produces more high voltage drive signal, the both required high-frequency driving signal of transducing sheet at L2 like this.

The area of the electrode coating at the transducing sheet back side of ultrasonic ultrasonic delay line memory of the present utility model is between 10 square millimeters to 40 square millimeters.To between the 1MH, the inductance value of L2 is 0.1 to 2 times of L1 inductance value to the inductance value of the inductance L 1 in the ultrasonic ultrasonic delay line memory drive circuit at 1UH.

The utility model is simple in structure, and the low-voltage occasion is used, and the mist amount is big, the efficient height.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is circuit diagrams of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: ultrasonic atomization transducing sheet 1, electrode coating 2.

As shown in Figure 1, the utility model ultrasonic atomization transducing sheet comprises by electrode and drive circuit to be formed, the back side at ultrasonic atomization transducing sheet 1 is provided with electrode coating 2, the area of the electrode coating at the ultrasonic atomization transducing sheet back side is less than 50 square millimeters, the electrode coating at the back side is meant that electrode coating that does not contact water, the area of the electrode coating at the ultrasonic atomization transducing sheet back side is 30 square millimeters, transducing sheet backplate area need only be reduced, just can use under power is condition below the 5W, mist amount and efficient all can be high more a lot of than traditional atomizer.The shape of ultrasonic atomization transducing sheet backplate coating can be square, circular or other shapes.

As shown in Figure 2, as shown in Figure 1, the utility model ultrasonic atomization transducing sheet comprises by electrode and drive circuit to be formed, the back side at ultrasonic atomization transducing sheet 1 is provided with electrode coating, the electrode coating at the back side is meant that electrode coating that does not contact water, and the area of the electrode coating at the ultrasonic atomization transducing sheet back side is 30 square millimeters.Drive circuit comprises Q1MOS pipe and inductance L 1 and inductance L 2, and inductance L 1 is mutual inductance with inductance L 2, and the transducing sheet links to each other with inductance L 2.The utility model reduces transducing sheet backplate area, and the use separately driven circuit comes the switching drive signal to the metal-oxide-semiconductor certain frequency, by boosting of L1 and L2 mutual inductance, just can under being condition below the 5W, use low-voltage power, and mist amount and efficient all can be high more a lot of than traditional atomizer.
