Problems solved by technology

However, this patent application uses the atomizing sheet scanning circuit for frequency scanning and control, which cannot solve the defect of increasing the cost of the capacitor adjustment method
[0005] In short, the current traditional RC circuit method for generating driving frequency is difficult to achieve high-precision frequency control due to area and structural constraints.

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 As shown, the high-frequency precision and high-linear atomization sheet control circuit realized by the present invention includes a PLL unit, a control unit and an atomization sheet unit, wherein the PLL unit receives a control signal from the control unit to generate a specific frequency square wave. The control unit receives the voltage signal generated by the atomizing sheet and generates a control signal. The atomizing sheet unit is driven by the square wave generated by the PLL unit and outputs a voltage signal.

[0021] The frequency range output by the PLL unit of...

Abstract

The invention discloses an atomizing film control circuit with high frequency precision and high linearity. The atomizing film control circuit comprises a PLL (Phase Locked Loop) unit, a control unitand an atomizing film unit, wherein the PLL unit receives a control signal of the control unit to generate square waves of a specific frequency, the control unit receives a voltage signal generated byan atomizing film to generate a control signal, and the atomizing film unit receives square waves generated by the PLL unit, is driven and outputs a voltage signal. The atomizing film control circuitcan search the optimal resonance frequency of the atomizing film and ensure the best atomizing efficiency by using a method with small step, high precision and high linearity.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a control circuit and method of an atomizing sheet. Background technique [0002] Ultrasonic atomizer uses high-frequency vibration (oscillation frequency is 1.7MHz or 2.4MHz, which is beyond the range of human hearing, and the electronic vibration is absolutely harmless to human body and animals), and through the high-frequency resonance of the ceramic atomizer, water and other The liquid is dispersed to produce a natural and elegant water mist without heating or adding any chemical reagents. Compared with the heating atomization method, the energy saving is 90%. But the characteristic of the atomizing sheet is that only at the resonance point can the best atomization effect be produced, and the driving frequency slightly deviates from the resonance point, and the atomization amount will drop sharply. At present, the industry adopts the method of RC osc...
