本实用新型涉及吸尘器,具体涉及一种吸尘器的调速器。 The present invention relates to a vacuum cleaner, particularly to a vacuum cleaner governor.

本实用新型目的是提供一种可以用于手柄调速、电路结构简单、可靠性好、符合安全认证要求的吸尘器调速器。 Object of the present invention is to provide a handle for control, a simple circuit structure, good reliability, safety meet certification requirements cleaner governor.

为达到上述目的,本实用新型采用的技术方案是:一种隔离型变阻抗吸尘器调速器,包括双向可控硅、双向触发二极管、电容和电容的充电回路,双向可控硅与吸尘器电机串联,双向触发二极管的一端连接到双向可控硅的控制极,另一端与电容相连,所述充电回路中串联有一个隔离变压器的初级,隔离变压器的次级与一个可变阻抗相连。 To achieve the above object, the technical solution of the present invention is that: a separator-type vacuum cleaner dependent impedance converter, comprising a triac, diac, a capacitor and a capacitor charging circuit, triac in series with the vacuum cleaner motor one end of diac connected to the control electrode of the triac, is connected to the other end of the capacitor, the charging circuit in series with an isolation transformer has primary, secondary and isolation transformer is connected to a variable impedance.
