Description

一种微波发生电路及微波发生装置 技术领域
本发明属于微波电路领域，具体地说，涉及一种微波发生电路及微波发生装置。
背景技术
香烟燃烧时会产生烟雾，由于香烟燃烧时温度较高，最高温度可以超过800℃，在高温条件下产生的烟雾会包含大量有害物质，烟雾弥漫在空气中形成二手烟，二手烟会对吸烟者周围的人群造成伤害。并且香烟燃烧时会有明火，部分烟民吸食完香烟后并未将烟头彻底灭火，容易引起火灾，具有较高的安全隐患。
随着加热不燃烧电子烟的出现，让广大烟民有了更多的选择。加热不燃烧电子烟是以“加热不燃烧”为理念所设计的一种烟具，与传统香烟相比，加热不燃烧电子烟的工作温度要远远低于传统香烟燃烧时的温度，加热不燃烧电子烟仅仅对烟叶进行加热，让烟叶散发出烟草香味，满足使用者的需求。加热不燃烧电子烟的工作温度通常在250℃至350℃范围内，而烟叶在温度低于350℃时不会燃烧，避免了产生传统香烟燃烧时产生的有害物质，同时不会在空气中形成二手烟，减少了对周围人群的伤害。
现有的一种加热不燃烧电子烟内设有微波射频电路，通过微波射频电路来发射微波，用微波对烟草介质进行加热来产生烟雾。现有微波射频电路供电电压较高，使用电池供电需要使用升压电路，导致分立元件的体积较大，增大电子烟的体积，不方便用户使用。
有鉴于此特提出本发明。

本发明通过将充电探针210设置为第二连接部211和凸出部212，并且第二连接部211的直径大于通孔213的直径，第二连接部211第二端卡在第一侧板205远离电子烟201一侧，让电路板215和第一侧板205之间具有一定的间隙，避免电路板215与第一侧板205之间挤压导致影响电路板215正常工作。
如图3所示，本发明优选的另一实施例中，充电探针210的凸出部212远离第二连接部211一端为半球形。在将充电探针210插入充电接口214内时，能够让充电探针210滑进充电接口214内，减小将充电探针210插入充电接口214时的阻力，方便用户使用。
本发明实施例中，充电探针210包括给电子烟201充电的电源探针和用于识别电子烟201与充电装置203连接的识别探针，电源探针包括电源正极探针、电源负极探针和用于指示充电状态的充电指示探针，充电接口214包括与电源正极探针、电源负极探针、充电指示探针和识别探针分别适配的电源正极接口、电源负极接口、充电指示接口和识别接口。
在对电子烟201充电时，将电源正极探针、电源负极探针、充电指示探针和识别探针分别插入对应的电源正极接口、电源负极接口、充电指示接口和识别接口后，对识别探针的电平进行检测。若识别探针的电平从高电平变为低电平，则电子烟201与充电装置203连接成功，充电装置203通过电源探针给电子烟201充电。
本发明实施例中，在充电装置203内设有电池，电池连接至所述电路板215，电池通过电路板215上的探针向电子烟201充电。同时在充电装置203内设有用于给电池充电的充电电路，充电电路上预留有充电端口，充电端口卡接在第一壳体204上的安装孔中。
在用充电装置203给电子烟201多次充电后，可以通过充电端口给充电装置203内的电池充电，保证充电装置203内电池的电量，方便用户使用。
本发明实施例中，在第二壳体208上设有多个指示灯，指示灯包括用于展示电子烟201充电状态的充电指示灯，以及用于展示充电装置203充放电状态的充电指示灯。
当充电装置203给电子烟201充电时，充电指示灯显示红色，并且在电子烟201充电过程中充电指示灯不停闪烁，表示电子烟201正在充电；在电子烟201充电完毕后，充电指示灯显示绿色，并且充电指示灯常亮，表示电子烟201充电完毕。
在给充电装置203充电时，充电指示灯闪烁，同时用充电指示灯常亮的数量来表示充电装置203内电池的电量。若所有充电指示灯均常亮，则表示充电装置203内的电池已经达到满电状态，需要停止向充电装置203充电；若所有充电指示灯均熄灭，表示充电装置203内的电池电量过低，需要及时对充电装置203进行充电。
本发明通过设置充电指示灯，可以让用户清楚的了解电子烟201的充电状态，方便用户使用。同时本发明设置充电指示灯，用充电指示灯来表示充电装置203的电量，让用户可以在充电装置203电量不足时及时对充电装置203进行充电，提高充电装置203的续航效果，方便用户使用。
本发明实施例中，电子烟201采用微波加热方式，与采用发热电阻丝加热的方式相比，微波加热时温度较低，具有更高的安全性，同时微波加热不会产生有害物质，减小对用户身体造成的损害。
本发明实施例中电子烟201内设有微波发生装置，微波发生装置包括微波腔室和设在微波腔室内的微波天线，微波腔室顶部设有开口，微波腔室通过开口与电子烟201外部连通。在使用电子烟201时，将烟弹从开口处插入微波腔室内，然后开启微波发生装置，烟弹在微波作用下产生烟雾，满足用户的使用需求。同时本发明在微波腔室内设有波纹环，通过波纹环来抑制微波辐射。
本发明还介绍了一种分体式电子加热烟具充电方法，充电装置203上的充电探针210接入电子烟201上的充电接口214后，获取电子烟201的电压，若电子烟201的电压低于第一设定电压，则充电装置203通过充电探针210向电子烟201充电；在电子烟201的电压高于第二设定电压后，充电装置203停止向电子烟201充电，电子烟201进入休眠状态。
本发明实施例中，充电装置203上的充电探针210接入电子烟201上的充电接口214后，识别探针处的电平由高电平变为低电平，充电装置203识别到电子烟201接入。在充电装置203识别到电子烟201接入后，充电装置203向电子烟201充电。
通常电池的电量越高，电池的输出电压也越高。当电池的电量过低时，电池无法正常向负载供电。即使电池内仍然存有一定的电量，但由于电池的输出电压过低，无法满足负载的需求，使负载无法正常工作。而在电池的电量过高时，如果继续向电池充电，会降低电池的使用寿命。
本发明实施中，在对电子烟201进行充电时，首先检测充电装置203上的识别探针是否成功连接至电子烟201上的识别接口，在识别探针成功接入识别接口后，识别探针处的电平由高电平变为低电平，此时充电装置203识别到电子烟201接入。在电子烟201接入充电装置203后，检测电子烟201的电压，将检测到的电子烟201的电压与预先设定的第一电压进行比较，只有当检测到的电子烟201的电压低于第一设定电压时，充电装置203才会向电子烟201充电。随着充电过程的进行，电子烟201内电池的电量逐渐提升，电池的电压也逐渐升高，当电子烟201的电压高于第二设定电压后，充电装置203停止向电子烟201充电，电子烟201进入休眠状态，提高电子烟201内电池的使用寿命。
