Description

一种超声雾化片振荡控制电路及超声波电子烟 技术领域
本发明属于电子烟技术领域，特别涉及一种超声雾化片振荡控制电路及超声波电子烟。
背景技术
现有的超声雾化片振荡控制电路有两种，第一种是采用一路PWM波控制超声雾化片进行单边振荡，包括微处理器及第一驱动振荡电路，其中微处理器的输出端通过第一驱动振荡电路与超声雾化片的一端电连接。第二种是采用两路PWM波控制超声雾化片进行双边振荡，其在第一种振荡控制电路的基础上增加了第二驱动振荡电路，微处理器的第一输出端通过第一驱动振荡电路与超声雾化片的第一端电连接，微处理器的第二输出端通过第二驱动振荡电路与超声雾化片的第二端电连接，微处理器同时输出两路互补的PWM波以控制超声雾化片进行双边振荡。
现有的超声雾化片振荡控制电路具有以下缺点：
第一，在双边振荡结构中，由于需要微处理器同时输出两路互补的PWM波，从而限制了微处理器的选型范围，增加了使用成本。
第二，现有振荡控制电路中的超声雾化片只有一种工作模式，即单纯单边振荡或单纯双边振荡，因而其额定功率固定不可调，同时由于有极性超声雾化片只能进行单边振荡，无极性超声雾化片可进行双边振荡，因而双边振荡的超声雾化片振荡控制电路不适用于有极性超声雾化片。可见，现有超声雾化片振荡控制电路不便于应用于不同种类的超声雾化片，不能满足不同用户群体的使用需求。
第三，由于现有的超声波电子烟中仅设有一片超声雾化片，因而工作时该超声雾化片进行反复振荡。由于超声雾化片是易耗品，寿命较短，容易因高温、过流等原因而烧坏，所以经常发生因超声雾化片损坏而无法出烟的情况，影响用户体验。再者，由于超声雾化片长时间大雾化量工作，随着时间的推移其工作效率会降低，因而会出现超声雾化片雾化量过小的情况，出烟量变小，影响用户体验。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种超声雾化片振荡控制电路及超声波电子烟。
为解决需要微处理器同时输出两路互补PWM波的技术问题，本发明所采用的技术方案是：
一种超声雾化片振荡控制电路，包括微处理器、第一驱动振荡电路和第二驱动振荡电路，第一驱动振荡电路的输出端与第一超声雾化片的第一端电连接，第二驱动振荡电路的输出端与第一超声雾化片的第二端电连接，其特点是还包括第一反相器，第一反相器的输入端、第二驱动振荡电路的输入端均与微处理器的第一输出端电连接，第一反相器的输出端与第一驱动振荡电路的输入端电连接。
借由上述结构，由于微处理器的输出端与第二驱动振荡电路的输入端电连接，同时，微处理器的输出端通过第一反相器与第一驱动振荡电路的输入端电连接，因此，微处理器输出的一路PWM波转换成了两路互补的PWM波，并分别用于控制第一驱动振荡电路、第二驱动振荡电路工作。可见，在本发明中，微处理器仅需要输出一路PWM波也可以控制第一超声雾化片进行双边振荡，对微处理器的选型没有特殊要求，降低了使用成本。
进一步地，还包括输出两路互补电平的互斥电路，第一反相器的输出端通过互斥电路与第一驱动振荡电路的输入端电连接，微处理器的第一输出端通过互斥电路与第二驱动振荡电路的输入端电连接。
为了排除微处理器内部的死区干扰以及第一反相器的延时作用，增设互斥电路，可以确保输送至第一驱动振荡电路、第二驱动振荡电路的两路信号为互补信号，防止出现因第一驱动振荡电路和第二驱动振荡电路同时导通而不出烟的情况，使第一超声雾化片的出烟量更加稳定，用户体验好。
作为一种优选方式，所述互斥电路包括第二反相器、第三反相器、第一或门、第二或门；第一反相器的输出端、第二反相器的输出端均与第二或门的输入端电连接，第二或门的输出端通过第三反相器与第一驱动振荡电路的输入端电连接；微处理器的第一输出端、第三反相器的输出端均与第一或门的输入端电连接，第一或门的输出端通过第二反相器与第二驱动振荡电路的输入端电连接。
进一步地，为解决超声雾化片工作只能在一种工作模式下工作的技术问题，本发明所采用的技术方案是：还包括用于控制第一驱动振荡电路是否工作的切换电路，微处理器的第二输出端与切换电路的控制端电连接，切换电路的输出端与第一驱动振荡电路电连接。
借由上述结构，控制器通过切换电路控制第一驱动振荡电路是否工作。当控制器通过切换电路控制第一驱动振荡电路工作时，第一驱动振荡电路和第二驱动振荡电路均工作，此时第一超声雾化片工作在双边振荡模式，功率大，烟雾量大，适用于无极性超声雾化片。当控制器通过切换电路控制第一驱动振荡电路不工作时，仅有第二驱动振荡电路工作，此时第一超声雾化片工作在单边振荡模式，功率小，烟雾量较小，适用于有极性超声雾化片。可见，由于设置了切换电路，因而可以根据用户使用需求选择第一超声雾化片的工作模式，同时也可以根据第一超声雾化片的种类选择对应的工作模式，应用范围广。
作为一种优选方式，所述第一驱动振荡电路包括放大器、第一电阻、第一MOS管、第一电感、第一电容，第一反相器的输出端与放大器的第一输入端电连接，放大器的第一输出端通过第一电阻与第一MOS管的栅极电连接，第一MOS管的源极接地，第一MOS管的漏极、第一电感的一端、第一电容的一端均与第一超声雾化片的第一端电连接，第一电感的另一端与电源正极电连接，第一电容的另一端接地。
作为一种优选方式，所述第二驱动振荡电路包括放大器、第二电阻、第二MOS管、第二电感、第二电容，微处理器的输出端与放大器的第二输入端电连接，放大器的第二输出端通过第二电阻与第二MOS管的栅极电连接，第二MOS管的源极接地，第二MOS管的漏极、第二电感的一端、第二电容的一端均与第一超声雾化片的第二端电连接，第二电感的另一端与电源正极电连接，第二电容的另一端接地。
进一步地，还包括电源模块，第一驱动振荡电路的电源端、第二驱动振荡电路的电源端均与该电源模块的输出端电连接。
作为一种优选方式，所述电源模块包括单节锂电池与升压模块，单节锂电池的输出端与升压模块的输入端电连接，升压模块的输出端为电源模块的输出端。
通过升压模块将单节锂电池电压升高至第一超声雾化片所需电压，可以简化电路，降低成本。
作为一种优选方式，所述切换电路包括第三MOS管、第四MOS管、第三电阻、第四电阻和第五电阻，第三电阻的一端、第三MOS管的漏极均与电源正极相连，第三电阻的另一端、第三MOS管的栅极均通过第四电阻与第四MOS管的漏极相连，第三MOS管的源极与第一驱动振荡电路相连，第四MOS管的栅极、第五电阻的一端均与微处理器的第二输出端相连，第四MOS管的源极、第五电阻的另一端均接地。
进一步地，还包括电源模块，所述电源模块包括升压芯片、第三电容、第四 电容和第五电容，升压芯片的输入端、第三电容的一端均与供电正极电连接，升压芯片的输出端、第四电容的一端、第五电容的一端均与放大器的电源端电连接，升压芯片的接地端、第三电容的另一端、第四电容的另一端、第五电容的另一端均接地。
进一步地，为解决超声雾化片容易损坏且工作效率下降快的技术问题，本发明所采用的技术方案是：还包括第二超声雾化片和第三驱动振荡电路，微处理器的第三输出端通过第三驱动振荡电路与第二超声雾化片的第一端电连接，第二超声雾化片的第二端接地。
借由上述结构，本发明包括第一超声雾化片和第二超声雾化片共两片超声雾化片，两超声雾化片可分别谐振。本发明有两种工作模式：第一种工作模式中，同一时刻仅有一片超声雾化片振荡，在此工作模式下，当某片超声雾化片损坏或因其它情况(如过温保护、过流保护)而无法出烟时，可及时切换至另一超声雾化片工作，避免出现无法出烟的情况。第二种工作模式中，两超声雾化片同时工作且以小于额定雾化量的小雾化量工作，可以延长单片超声雾化片的工作寿命，在某片超声雾化片雾化量变小的情况下，可相应提高另一片超声雾化片的雾化量，使总体出烟量保持不变，提高电子烟的使用品质。其中雾化量是指单位时间内超声雾化片振荡产生烟雾的量。
进一步地，还包括用于检测第一超声雾化片工作功率的第一功率检测电路，第一功率检测电路的输出端与微处理器的第一输入端电连接。
进一步地，还包括用于检测第二超声雾化片工作功率的第二功率检测电路，第二功率检测电路的输出端与微处理器的第二输入端电连接。
借由上述结构，如果某一路超声雾化片因损坏而不出烟或因损耗而烟雾减小，就可以通过相应的功率检测电路检测到并将检测结果发送至微处理器，微处理器通过调大另一路超声雾化片的振荡频率，可使总体出烟量保持不变，提高电子烟的使用品质和寿命。
基于同一个发明构思，本发明还提供了一种超声波电子烟，包括所述的超声雾化片振荡控制电路。
与现有技术相比，本发明具有以下优点：
第一，通过仅输出一路PWM波的微处理器实现第一超声雾化片的双边振荡，对微处理器的选型没有特殊要求，降低了使用成本；同时第一驱动振荡电路和第二驱动振荡电路不会同时导通，工作可靠，出烟量稳定，用户体验好。
第二，第一超声雾化片能够在单边振荡工作模式和双边振荡工作模式之间进行自由切换，可以调整产品的额定功率，适用于不同种类的超声雾化片，能够满足不同用户群体的使用需求，应用范围更广。
第三，当第一超声雾化片或第二超声雾化片中的某一片损坏时，可及时切换至另一正常的超声雾化片工作，避免出现无法出烟的情况；在两片超声雾化片同时工作的情况下，可使得两超声雾化片同时以小于额定雾化量的小雾化量工作，可以延长单片超声雾化片的工作寿命，在某片超声雾化片雾化量变小的情况下，可相应提高另一片超声雾化片的雾化量，使总体出烟量保持不变，提高电子烟的使用品质和寿命。

所述互斥电路6包括第二反相器U2、第三反相器U4、第一或门U3、第二或门U5；第一反相器4的输出端、第二反相器U2的输出端均与第二或门U5的输入端电连接，第二或门U5的输出端通过第三反相器U4与第一驱动振荡电路2的输入端电连接；微处理器1的第一输出端、第三反相器U4的输出端均与第一或门U3的输入端电连接，第一或门U3的输出端通过第二反相器U2与第二驱动振荡电路3的输入端电连接。
所述第一驱动振荡电路2包括放大器U1、第一电阻R1、第一MOS管Q1、第一电感L1、第一电容C1，第一反相器4的输出端与放大器U1的第一输入端电连接，放大器U1的第一输出端通过第一电阻R1与第一MOS管Q1的栅极电连接，第一MOS管Q1的源极接地，第一MOS管Q1的漏极、第一电感L1的一端、第一电容C1的一端均与第一超声雾化片J1的第一端电连接，第一电感L1的另一端与电源正极电连接，第一电容C1的另一端接地。
所述第二驱动振荡电路3包括放大器U1、第二电阻R2、第二MOS管Q2、第二电感L2、第二电容C2，微处理器1的输出端与放大器U1的第二输入端电连接，放大器U1的第二输出端通过第二电阻R2与第二MOS管Q2的栅极电连接，第二MOS管Q2的源极接地，第二MOS管Q2的漏极、第二电感L2的一端、第二电容C2的一端均与第一超声雾化片J1的第二端电连接，第二电感L2的另一端与电源正极电连接，第二电容C2的另一端接地。
互斥电路6可以有效保证两路MOS管(第一MOS管Q1、第二MOS管Q2)不会同时导通，确保出烟稳定。

如图1所示，在本实施例中，电源模块5由单节锂电池充放电保护电路和升压电路组成，具有过充和过压保护功能，同时防止后端电路过流及短路。电源模块5采用单节锂电池501升压的方式，为后端高频它激式双边振荡电路提供大约30W功率的电源。

随后，放大器U1进行驱动信号放大，然后第一MOS管Q1、第二MOS管Q2在PWM波的控制下交替开关工作，使第一超声雾化片J1和电感电容形成谐振，振荡烟油产生烟雾。
