因此，当用户吸烟时，当储油腔11中储备有烟油时，发热金属丝L2中伸入储油腔11的一段被烟油浸泡使得其热量被烟油吸收，温度传感器检测到该段发热金属丝L2的温度不会太高，当储油腔11中的烟油将要用完时，该段发热金属丝L2脱离烟油浸泡，抽烟时该段发热金属丝L2的温度会迅速升高并超过阈值，此时温度传感器通过检测该段发热金属丝L2的温度迅速升高而获知储油腔11中的烟油用完。本实施例中，温度传感器可以检测伸入所述储油腔11的底部的所述发热金属丝L2的温度，并将所述发热金属丝L2的温度信号转化成电信号传送给所述保护电路，保护电路则根据所述电信号判断伸入所述储油腔11的底部的所述发热金属丝L2的温度，在所述温度超出阈值时，对所述电子烟进行保护处理，即由保护电路对温度进行比较并在温度超出阈值时对电子烟进行保护处理。此外，也可以由温度传感器在检测到伸入所述储油腔11的底部的所述发热金属丝L2的温度超出阈值时，将温度信号转化为电信号传送给保护电路，保护电路收到该电信号则对电子烟进行保护处理。故本发明可以通过温度检测提前预知烟油用完，并进行保护处理，有效预防因过渡吸烟导致的电热丝干烧造成的产生烧焦异味及释放有毒有害气体，保证了用户的身体健康，提高了用户体验，提高了安全性。Therefore, when the user smokes, when the oil storage chamber 11 is filled with the smoke oil, a portion of the heat generating wire L2 that protrudes into the oil storage chamber 11 is soaked by the smoke oil so that the heat is absorbed by the smoke oil, and the temperature sensor detects the section. The temperature of the heating wire L2 is not too high. When the oil in the oil storage chamber 11 is about to be used up, the heating wire L2 is immersed in the soot oil, and the temperature of the heating wire L2 rises rapidly when smoking. And exceeding the threshold value, at this time, the temperature sensor knows that the smoke oil in the oil storage chamber 11 is used up by detecting that the temperature of the heating wire L2 is rapidly increased. In this embodiment, the temperature sensor can detect the temperature of the heating wire L2 protruding into the bottom of the oil reservoir 11 and convert the temperature signal of the heating wire L2 into an electrical signal to be transmitted to the protection circuit. The protection circuit determines the temperature of the heating wire L2 that protrudes into the bottom of the oil reservoir 11 according to the electrical signal, and protects the electronic cigarette when the temperature exceeds a threshold, that is, protection The circuit compares the temperature and protects the electronic cigarette when the temperature exceeds a threshold. In addition, when the temperature of the heating wire L2 protruding into the bottom of the oil reservoir 11 exceeds a threshold value, the temperature signal may be converted into an electrical signal and transmitted to the protection circuit, and the protection circuit receives the The electrical signal protects the electronic cigarette. Therefore, the invention can predict the exhaustion of the smoke oil in advance by the temperature detection, and carry out the protection treatment, thereby effectively preventing the burnt odor caused by the dry burning of the electric heating wire caused by the transitional smoking and releasing the toxic and harmful gas, thereby ensuring the health of the user and improving the health of the user. The user experience improves security.
可选的，参阅图1、图2或图4所示，所述雾化组件1包括雾化套12，所述雾化套12一端连接有用于雾化烟油的具有所述电热丝L1的电热丝组件，所述雾化套12的另一端设置有吸嘴13，其中，所述电热丝组件与所述电池杆组件2电连接；所述雾化套12内插设有将电热丝L1雾化的烟雾排出至所述吸嘴13的通气管14，所述通气管14与所述雾化套12之间形成用于存储烟油的储 油腔11。其中，该吸嘴13为金属材料制件，该吸嘴13的外端面为球面，使得该吸嘴13具有更加美观及便于清理污垢等优点。Optionally, referring to FIG. 1 , FIG. 2 or FIG. 4 , the atomization assembly 1 includes an atomization sleeve 12 , and one end of the atomization sleeve 12 is connected with the heating wire L1 for atomizing the tobacco oil. a heating wire assembly, the other end of the atomizing sleeve 12 is provided with a suction nozzle 13 , wherein the heating wire assembly is electrically connected to the battery rod assembly 2; the atomizing sleeve 12 is internally provided with a heating wire L1 The atomized smoke is discharged to the vent pipe 14 of the suction nozzle 13, and the vent pipe 14 and the atomization sleeve 12 form a reservoir for storing the smoke oil. Oil chamber 11. The nozzle 13 is made of a metal material, and the outer end surface of the nozzle 13 is a spherical surface, so that the nozzle 13 has the advantages of more beautiful appearance and easy cleaning of dirt.
其中，由图1、图2或图4可知，储油腔11位于通气管14的外侧，即所述储油腔11环绕所述通气管14的外周设置。1 , 2 or 4 , the oil reservoir 11 is located outside the vent tube 14 , that is, the oil reservoir 11 is disposed around the outer circumference of the vent tube 14 .
一个实施方式中，该所述雾化组件1还包括与所述储油腔11相连通的储油板15，所述储油板15由吸油材料制成，所述电热丝L1与所述储油板15抵接并用于雾化所述储油板15上的烟油。这样，储油腔11中的烟油流入储油板15，电热丝L1吸收储油板15上的烟油进行雾化，不会造成因烟油过多而导致雾化不彻底形成烟油颗粒，使得雾化效果更好。其中，在本实施例中，所述储油板15卷绕呈柱状结构，可以理解的是，所述储油板15的结构不做具体限定。In one embodiment, the atomization assembly 1 further includes an oil storage plate 15 communicating with the oil reservoir 11 , the oil storage plate 15 being made of an oil absorbing material, the heating wire L1 and the storage The oil plate 15 abuts and is used to atomize the smoke oil on the oil storage plate 15. In this way, the oil in the oil storage chamber 11 flows into the oil storage plate 15, and the electric heating wire L1 absorbs the smoke oil on the oil storage plate 15 for atomization, and does not cause the atomization to form the smoke oil particles due to excessive smoke oil. To make the atomization effect better. In the present embodiment, the oil storage plate 15 is wound in a columnar structure. It is understood that the structure of the oil storage plate 15 is not specifically limited.
正常烟油量抽烟时，发热金属丝L2有一段伸入储油腔11中，烟油流入储油板15，电热丝L1对储油板15上的烟油进行雾化，小段发热金属丝L2浸泡在储油腔11的烟油中，其热量散发在烟油中，温度不会太高。When the normal amount of smoke oil smokes, the heating wire L2 has a section extending into the oil storage chamber 11, the smoke oil flows into the oil storage plate 15, the heating wire L1 atomizes the oil on the oil storage plate 15, and the small heating wire L2 Soaked in the oil of the oil storage chamber 11, the heat is emitted in the smoke oil, and the temperature is not too high.
烟油将要抽完，此时储油板15中还有烟油，电热丝L1继续对储油板15中的烟油进行雾化，不至于因发生干烧而产生异味等烟雾。而伸入储油腔11内的发热金属丝L2因脱离烟油的浸泡而产生高温，通过检测该段发热金属丝L2温度即可识别烟油是否将要抽完，温度传感器检测到该段发热金属丝L2的温度升高从而将温度信号转化为电信号发送给保护电路，由保护电路对电子烟进行保护处理。此时储油板15中还有部分烟油供给电热丝雾化，所以在烟油刚抽完时电热丝还可以雾化出正常烟雾，不会产生异味或有害物质，不仅起到提前预警的作用，还可以提高安全性。The smoke oil will be exhausted. At this time, there is smoke oil in the oil storage plate 15, and the heating wire L1 continues to atomize the smoke oil in the oil storage plate 15, so that smoke such as odor is not generated due to dry burning. The heating wire L2 extending into the oil storage chamber 11 generates high temperature due to the immersion of the smoke oil. By detecting the temperature of the heating wire L2, it is possible to identify whether the oil is to be exhausted, and the temperature sensor detects the heating metal. The temperature of the wire L2 is increased to convert the temperature signal into an electrical signal and sent to the protection circuit, and the protection circuit protects the electronic cigarette. At this time, some of the oil oil in the oil storage plate 15 is supplied with electric heating wire atomization, so that the electric heating wire can also atomize the normal smoke when the smoke oil is completely discharged, and does not generate odor or harmful substances, which not only plays an early warning. The role can also improve security.
请参阅图2及图3，所述电热丝L1与所述发热金属丝L2串联连接，且伸入储油腔11的底部。其中，发热金属丝L2可伸入储油腔11左侧的底部，也可以伸入储油腔11右侧的底部，图示所示设置方式不构成对本发明的限定。Referring to FIG. 2 and FIG. 3, the heating wire L1 is connected in series with the heating wire L2 and extends into the bottom of the oil reservoir 11. The heating wire L2 may extend into the bottom of the left side of the oil storage chamber 11 or may extend into the bottom of the right side of the oil storage chamber 11. The arrangement shown in the drawings does not constitute a limitation of the present invention.
