用户抽吸时,雾化腔内部气压呈负压,从进气通道100进入到雾化腔,控制电路启动加热片雾化多孔陶瓷体中吸附的液态介质。多孔陶瓷体的液态介质减少,在毛细作用力的作用下,多孔陶瓷体从储液腔4吸入油液,然后继续雾化。储液腔4的液态介质减少,气体空间增大,储液腔4气压出现过大的负压,空气从外壳的进气口63进入到空腔61,然后通过换气槽62进入储液腔4,实现气液平衡,从而让下液的速度与液态介质被雾化的速度相适配。When the user sucks, the air pressure inside the atomization cavity is negative, and it enters the atomization cavity from the air inlet channel 100, and the control circuit activates the heating plate to atomize the liquid medium adsorbed in the porous ceramic body. The liquid medium of the porous ceramic body is reduced. Under the action of the capillary force, the porous ceramic body sucks oil from the liquid storage cavity 4, and then continues to atomize. The liquid medium in the liquid storage chamber 4 decreases, and the gas space increases. The air pressure of the liquid storage chamber 4 is excessively negative. The air enters the cavity 61 from the air inlet 63 of the housing, and then enters the liquid storage chamber through the air exchange tank 62 4. Realize gas-liquid balance, so that the speed of the liquid is matched with the speed of the liquid medium being atomized.
再如图5、图6及图7所示,在本实施例中,该上座体11的上部包括倒圆台形外周面,壳体3包括圆柱形内周面,上座体11的中部设置有环形凸台116,倒圆台形外周面的顶部和凸台116的外周面分别与圆柱形内周面抵接,形成向换气槽62方向逐渐收窄的空腔61,其纵向横截面为上窄下宽。As shown in Figures 5, 6 and 7, in this embodiment, the upper part of the upper seat body 11 includes a rounded truncated cone-shaped outer circumferential surface, the housing 3 includes a cylindrical inner circumferential surface, and the middle of the upper seat body 11 is provided with a ring shape The boss 116, the top of the rounded truncated cone-shaped outer circumferential surface and the outer circumferential surface of the boss 116 respectively abut against the cylindrical inner circumferential surface to form a cavity 61 that gradually narrows toward the ventilation groove 62, and its longitudinal cross-section is upwardly narrow Lower width.
参照图8a-8c,由于毛细作用力,储液腔4经换气槽62进入空腔61的烟液会被吸附在倒V字型的顶部,从而储存在空腔61中。当用户抽吸时,储液腔4的液体减少,气压下降,被吸附在倒V字型顶部的烟油就会从换气槽62回流到储液腔4中。这种倒V字形结构设计,一方面可以防止烟油流出外壳,另一方面也可以使空腔61底部的烟油顺着倒V字形结构回流到储液腔4。其中,图8a-8c中的A,是不同情况下,烟液被吸附在倒V字型顶部的吸附量,具体地:8a-8c, due to the capillary force, the e-liquid that enters the cavity 61 from the liquid storage chamber 4 through the ventilation groove 62 will be adsorbed on the top of the inverted V shape, thereby being stored in the cavity 61. When the user sucks, the liquid in the liquid storage chamber 4 decreases and the air pressure drops, and the e-liquid adsorbed on the top of the inverted V shape will flow back into the liquid storage chamber 4 from the ventilation tank 62. This inverted V-shaped structure design can prevent the e-liquid from flowing out of the housing on the one hand, and on the other hand, it can also make the e-liquid at the bottom of the cavity 61 flow back to the liquid storage chamber 4 along the inverted V-shaped structure. Among them, A in Figures 8a-8c is the adsorption amount of the smoke liquid adsorbed on the top of the inverted V shape under different circumstances, specifically:
图8a是当搁置状态时,储液腔4的内部压力与外界压力相同时,烟油在换气槽62处形成油膜产生张力从而实现锁液,处于汽液平衡状态。Fig. 8a shows that when the internal pressure of the liquid storage chamber 4 is the same as the external pressure in the resting state, the e-liquid forms an oil film at the ventilating groove 62 to generate tension to achieve liquid lock and be in a vapor-liquid equilibrium state.
图8b是当搁置状态下,外界环境发生变化,例如出现外界负压,储液腔4内部压力大于外界压力时,烟液从换气槽62往空腔61进一步渗漏,由于空腔61为倒V字形结构,因此烟油在空腔61顶尖夹缝处被最大毛细力和张力牵引,从而实现锁液功能。而越往下毛细力和张力对烟油的牵引越小,直到张力被隔断,此时小部分的烟液会滞留在凸台116上,通过凸台116避免烟液从进气口63流出。Figure 8b shows that when the external environment changes in the resting state, for example, there is external negative pressure, and the internal pressure of the liquid storage chamber 4 is greater than the external pressure, the smoke liquid further leaks from the ventilation slot 62 to the cavity 61, because the cavity 61 is Inverted V-shaped structure, so the e-liquid is drawn by the maximum capillary force and tension at the gap between the center of the cavity 61, thereby achieving the liquid locking function. The lower the capillary force and the tension, the less the e-liquid will be drawn until the tension is cut off. At this time, a small part of the e-liquid will stay on the boss 116, and the e-liquid will be prevented from flowing out of the air inlet 63 through the boss 116.
图8c是当抽吸状态时,储液腔4的液态介质减少,气体空间增大,储液腔4气压出现过大的负压,储液腔4内部压力小于外界压力时,外界压力突破换气槽62处烟油的张力从而令外部空气进入储液腔4中,完成换气操作。同时,还能将吸附在倒V字型顶部的烟油挤回到储液腔4中,从而实现漏液回收利用。Figure 8c shows that when the liquid medium in the liquid storage chamber 4 is reduced, the gas space increases, and the air pressure in the liquid storage chamber 4 is excessively negative, when the internal pressure of the liquid storage chamber 4 is less than the external pressure, the external pressure breaks through and changes. The tension of the e-liquid at the air groove 62 causes external air to enter the liquid storage chamber 4 to complete the ventilation operation. At the same time, the e-liquid adsorbed on the top of the inverted V shape can be squeezed back into the liquid storage chamber 4, so as to realize the recovery and utilization of the leaked liquid.
在一些实施例中,换气槽62开设在倒圆台形外周面的顶部与圆柱形内周面抵接处的上座体11上或壳体3上。在本实施例中,换气槽62开设在倒圆台形外周面的顶部与圆柱形内周面抵接处的上座体11上。并且,换气槽62的槽深度向空腔61方向逐渐减小设置,该换气槽61足够小,以具有毛细力。优选地,换气槽61顶部的开口尺寸为1.0mm*0.3mm。In some embodiments, the ventilating groove 62 is opened on the upper seat 11 or the housing 3 where the top of the rounded cone-shaped outer circumferential surface abuts with the cylindrical inner circumferential surface.

In addition, the groove depth of the ventilating groove 62 is gradually reduced toward the cavity 61, and the ventilating groove 61 is small enough to have capillary force. Preferably, the size of the opening at the top of the ventilation groove 61 is 1.0 mm*0.3 mm.
在一些实施例中,进气口63与换气槽62呈上下设置,并在周向上错开设置。优选地,在本实施例中,为了进一步避免烟液从进气口63流出,设计了进气口63与换气槽62在周向上相对设置,液态介质从换气槽62进入到进气口63流出,需要流动半周的距离,因此可最大限度地避免烟液流出。In some embodiments, the air inlet 63 and the ventilation groove 62 are arranged up and down, and are staggered in the circumferential direction. Preferably, in this embodiment, in order to further prevent the smoke liquid from flowing out of the air inlet 63, the air inlet 63 and the ventilation groove 62 are designed to be arranged opposite to each other in the circumferential direction, and the liquid medium enters the air inlet from the ventilation groove 62 The 63 outflow requires a half-round distance to flow, so the outflow of smoke liquid can be avoided to the greatest extent.
