Figures 1 and 2 show the atomizer in the first embodiment of the present invention. The atomizer can form an electronic atomization device together with a battery device for providing atomization to liquid media such as e-liquid or liquid medicine. The atomizer includes a liquid storage chamber 4 for storing liquid, and a ventilation channel connecting the liquid storage chamber 4 with the outside. The ventilating passage includes: an air inlet 63 communicating with the outside, a cavity 61 communicating with the air inlet 63, and a ventilating groove communicating the cavity 61 and the liquid storage chamber 4. The liquid chamber is connected to the outside world to replenish air for the liquid storage chamber, realize gas-liquid balance, and make the liquid in the liquid storage chamber more smooth.

In some embodiments, the cavity 61 is a ring or a part of a ring. The end of the cavity 61 close to the gas exchange groove 62 has capillary force. When the liquid in the liquid storage cavity 4 overflows into the cavity 61, the cavity 61 is close to the exchange One end of the gas tank 62 locks the liquid by capillary force, which realizes the liquid lock in the resting state, and also realizes the recovery and utilization of the leaked liquid at the end of the cavity 61 close to the gas exchange tank 62 in the suction state.

In addition, the atomizer further includes an atomizing core 20. The cavity 61 may be a closed loop, or a segment or segmented ring. The cavity 61 surrounds or partially surrounds the atomizing core 20, so as to make full use of the space. In this embodiment, the cavity 61 is a closed loop.

In this embodiment, the cavity 61 gradually narrows toward the ventilation groove 62, so that the end of the cavity 61 close to the ventilation groove 62 has capillary force. Also, preferably, the longitudinal cross section of the cavity 61 is in an inverted V shape.

In this embodiment, the atomizer may include an atomization seat 1, an atomization assembly 2 installed in the atomization seat 1, and an atomization seat 1 sleeved on the battery device mechanically and electrically.上的壳3。 On the shell 3. Wherein, a liquid storage cavity 4 for storing liquid medium is defined between the atomization seat 1 and the housing 3. The atomization assembly 2 is connected to the liquid storage cavity 4 for liquid conduction, and an atomization cavity is defined between the atomization seat 1 and the atomization cavity is used to heat the atomized medium after the atomization assembly 2 is energized to mix with the outside air .

In this embodiment, the cavity 61 is enclosed by the inner wall of the housing 3 and a part of the outer wall of the atomization seat 1. In other embodiments, the cavity 61 may also be formed inside the atomization seat 1, and the atomization seat 1 and the housing 3 are immediately sleeved to form an air inlet 63 communicating with the cavity 61. The top of 1 is provided with a ventilating groove 62 communicating with the liquid storage chamber 4.

3 and 4 together, the atomization seat 1 in this embodiment includes a lower seat body 10 for mechanically and electrically connecting with the battery device, and an upper seat body 11 embedded on the top of the lower seat body 10 , The upper base 11 is used to carry the atomization assembly 2. The housing 3 is sleeved on the upper seat body 11 and the lower seat body 10, a liquid storage chamber 4 and a ventilation channel are defined between the housing 3 and the upper seat body 11, and the housing 3 and the lower seat body 10 are snap-fitted.

As shown in Figures 2 and 7, specifically, the upper seat body 11 includes an outer peripheral surface, the housing 3 includes an inner peripheral surface corresponding to the upper seat body 11, and the ventilation passage includes the outer peripheral surface of the upper seat body 11 and the inner peripheral surface of the housing 3. A cavity 61 is defined along the peripheral surface, at least one ventilation groove 62 opened on the upper seat 11 or the housing 3, and at least one air inlet 63 opened on the housing 3. Wherein, the ventilating tank 62 communicates with the liquid storage chamber 4 and the cavity 61, and the air inlet 63 communicates with the cavity 61 and the outside.

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.

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.

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:

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.

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.

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.
