The electronic atomization device 300 can be used for atomization of liquid substrates such as tobacco juice, liquid medicine and the like. The electronic atomizer 300 includes an atomizer 100 and a body assembly 200 connected to each other, the atomizer 100 is used for storing liquid substrate and atomizing the liquid substrate to form aerosol for a user to inhale, and the body assembly 200 is used for supplying power to the atomizer 100 so that the atomizer 100 can atomize the liquid substrate to form aerosol.
The atomizer 100 generally comprises, among other things, an atomizing sleeve 10, a base 20, a seal 30, an atomizing core 40, and a base 50.
The nebulizing sleeve 10 has a reservoir 12, inside the nebulizing sleeve 10 there is provided a vent tube 14, in other words the vent tube 14 is provided inside the reservoir 12, the reservoir 12 being intended to store a liquid substrate and the vent tube 14 being intended to direct the aerosol to the mouth of a user.
As shown in fig. 3, the base 20 is provided with a ventilation hole 22, a liquid inlet cavity 21 and a smoke outlet 23, the ventilation hole 22 can be communicated with the liquid storage cavity 12 and the atmosphere, the liquid inlet cavity 21 is communicated with the liquid storage cavity 12, the liquid inlet cavity 21 guides the liquid substrate to the atomizing core 40 so that the atomizing core 40 atomizes the liquid substrate to form smoke, and the ventilation pipe 14 is connected with the smoke outlet 23 so as to guide the smoke to the oral cavity of a user through the smoke outlet 23.
As shown in fig. 3 and 4, the sealing member 30 is disposed between the atomizing sleeve 10 and the base 20, and the sealing member 30 covers the airing hole 22, and the sealing member 30 is provided with an escape port 310 corresponding to the liquid inlet chamber 21 and an outlet port 312 corresponding to the smoke outlet 23.
Wherein the sealing member 30 is used to seal the gap between the side wall of the nebulizing sleeve 10 and the base 20, and the sealing member 30 covers the ventilation hole 22, and the sealing member 30 also seals the gap between the ventilation tube 14 and the side wall of the smoke outlet 23. It can be seen that the side of the sealing member 30 facing the reservoir 12 will bear the hydraulic pressure and the air pressure in the reservoir 12, the side of the sealing member 30 covering the ventilation hole 22 will bear the atmospheric pressure, and the sealing member 30 is made of elastic material, such as silicon rubber, plastic, etc., which has good elastic performance, so that the portion of the sealing member 30 corresponding to the ventilation hole 22 can be jacked up and restored under the action of the pressure forces of the two sides.
Specifically, when the pressure from the side of the ventilating hole 22 on the part of the sealing member 30 at the position of the ventilating hole 22 is greater than the pressure from the side of the liquid storage cavity 12, the part of the sealing member 30 is jacked up to not cover the ventilating hole 22, so that the ventilating hole 22 is communicated with the liquid storage cavity 12, and air from the outside enters the liquid storage cavity 12 to increase the air pressure in the liquid storage cavity 12, thereby avoiding the situation that the liquid in the liquid matrix is unsmooth due to too low air pressure or even negative pressure in the liquid storage cavity 12, so that the atomizing core 40 is burnt dry to generate scorched smell; when the pressure from the side of the ventilation hole 22 on the part of the sealing element 30 at the ventilation hole 22 is smaller than the pressure from the side of the reservoir chamber 12, the sealing element 30 rebounds and recovers due to the hydraulic pressure, the air pressure in the reservoir chamber 12 and the elastic force of the sealing element itself, thereby sealing the ventilation hole 22 and isolating the reservoir chamber 12 from the ventilation hole 22, and further reducing or even eliminating the risk of leakage of the reservoir chamber 12 through the ventilation hole 22.
As shown in fig. 4, the sealing member 30 includes a side wall sealing portion 32, an end surface covering portion 31, and a side wall sealing portion 33, the side wall sealing portion 32 is connected to an outer peripheral side of the end surface covering portion 31, the side wall sealing portion 32 is disposed between the base 20 and the side wall of the atomizing sleeve 10, the end surface covering portion 31 covers an end surface of the base 20 facing the reservoir chamber 12, the end surface covering portion 31 further covers the ventilation hole 22, the side wall sealing portion 33 is connected to an inner peripheral side of the outlet 312 of the end surface covering portion 31 and disposed at a distance from the side wall sealing portion 32, and the side wall sealing portion 33 is disposed between the ventilation pipe 14 and. Wherein the end face covering portion 31 is provided with an escape opening 310 and an outlet 312. The part of the end surface covering part 31 corresponding to the ventilation hole 22 is jacked up and rebounded to be restored, and the ventilation hole 22 is determined to be communicated with and isolated from the liquid storage cavity 12.
Wherein, after the part of the end face covering part 31 is jacked up, the ventilation hole 22 can be communicated with the liquid storage cavity 12 through the avoidance port 310.
In one embodiment, referring to fig. 5, the end surface covering portion 31 is provided with a vent hole 314, the vent hole 314 is a through hole provided on the end surface covering portion 31 and used for communicating the liquid storage cavity 12, the vent hole 314 is arranged in a staggered manner with the ventilation hole 22, and when the end surface covering portion 31 is not jacked up and covers the ventilation hole 22, the vent hole 314 is isolated from the ventilation hole 22 and is not communicated. The ventilation holes 314 and the ventilation holes 22 can be arranged at overall staggered intervals or in tangential contact with each other at the edges. When the part of the end surface covering part 31 corresponding to the ventilation hole 22 is jacked up, the ventilation hole 314 is caused to deflect or deflect towards the ventilation hole 22, so that the ventilation hole 314 is communicated with the ventilation hole 22, the ventilation hole 22 is communicated with the liquid storage cavity 12 through the ventilation hole 314, and after the end surface covering part 31 rebounds to re-cover the ventilation hole 22, the ventilation hole 314 is isolated from the ventilation hole 22. In one embodiment, the ventilation holes 314 and the ventilation holes 22 are circular and arranged in tangential contact at the edges.
Specifically, one or even a plurality of vent holes 314 may be provided in the end surface covering portion 31 around the peripheral side of the vent holes 22, and the provision of the plurality of vent holes 314 ensures that the vent holes 22 communicate with the vent holes 314 after the portion of the end surface covering portion 31 is jacked up.
In some embodiments, referring to fig. 6, the end surface covering portion 31 is provided with a shielding pad 313 corresponding to the position of the ventilation hole 22, and the shielding pad 313 covers the ventilation hole 22.
When the pressure of the shielding pad 313 towards the side of the ventilation hole 22 is greater than the pressure of the shielding pad 313 towards the side of the liquid storage chamber 12, the shielding pad 313 is jacked up, so that the ventilation hole 22 is communicated with the liquid storage chamber 12. When the pressure of the shielding pad 313 toward the ventilation hole 22 is less than the pressure of the shielding pad 313 toward the reservoir 12, the shielding pad 313 rebounds to cover the ventilation hole 22.
Specifically, the shielding pad 313 has a half-moon shape corresponding to the minor arc, and the shielding pad 313 does not turn sideways and cannot rebound when being jacked up, thereby ensuring that the shielding pad 313 rebounds to cover the ventilation hole 22. One part of the edge of the shielding pad 313 is integrated with the end face covering part 31, the other part of the edge is disconnected with the end face covering part 31, the shielding pad 313 is jacked up from the part of the edge disconnected with the end face covering part 31, and the liquid storage cavity 12 is communicated with the air vent 22. The shielding pad 313 is a part of the end surface covering portion 31, and is formed by cutting the end surface covering portion 31 around a position corresponding to the ventilation hole 22. For example, an arc is cut on the end surface covering portion 31 around the position of the corresponding ventilation hole 22 to form a half moon-shaped shielding pad 313. The shielding pad 313 may also be in various shapes such as a trapezoid shape, and the present application does not specifically limit the shielding pad 313, and it is sufficient to ensure that the shielding pad 313 covers the ventilation hole 22 in time.
Therefore, by arranging the shielding pad 313, most of the end surface covering part 31 does not need to be jacked up to enable the ventilating holes 22 to be communicated with the liquid storage cavity 12, the shielding pad 313 can be jacked up to communicate the ventilating holes 22 with the liquid storage cavity 12 timely and efficiently, the risk that the liquid medium is unsmooth due to too low air pressure in the liquid storage cavity 12 is effectively reduced, the ventilating holes 22 can be timely covered after the air pressure in the liquid storage cavity 12 is recovered to be normal, and liquid leakage through the ventilating holes 22 is avoided.
In other embodiments, referring to fig. 7, the end surface covering portion 31 is provided with a blocking cover 318 at a position corresponding to the ventilation hole 22, the blocking cover 318 covers the ventilation hole 22, the blocking cover 318 includes a plurality of sub-cover bodies 319, and the plurality of sub-cover bodies 319 together cover the ventilation hole 22.
When the pressure of the side of the blocking cover 318 facing the ventilating hole 22 is greater than the pressure of the side of the blocking cover 318 facing the reservoir 12, the sub-cover 319 is lifted up, so that the ventilating hole 22 is communicated with the reservoir 12. When the pressure of the cover 318 toward the ventilation hole 22 is lower than the pressure of the cover 318 toward the reservoir 12, the sub-covers 319 are resiliently folded to close the ventilation hole 22.
When the sub-cover bodies 319 close and cover the ventilation holes 22, a part of the edge of each sub-cover body 319 and the end surface covering part 31 are integrally formed, and the other part of the edge of each sub-cover body 319 is abutted to each other to jointly cover the ventilation holes 22. Each sub-cover 319 is a part of the end surface covering portion 31, and is formed by cutting the end surface covering portion 31 around the position corresponding to the ventilation hole 22. For example, three slits are cut on the end surface covering portion 31 around the positions corresponding to the ventilation holes 22, thereby forming the sub-cover 319 in a fan shape.
As shown in fig. 7 and 8, each sub cover body 319 comprises a boss 3191 which is far away from the ventilation hole 22 and a thinning groove 3192 which faces the ventilation hole 22, the boss 3191 protrudes out of the main surface of the end surface covering part 31 to ensure that each sub cover body 319 can be rebounded and folded to cover the ventilation hole 22 after being jacked up, and the thinning groove 3192 thins the thickness of the sub cover body 319 to ensure that the sub cover body 319 is easy to jack up, so that the communication efficiency of the ventilation hole 22 and the liquid storage cavity 12 is improved. The area surrounded by the bosses 3191 may cover the entire ventilation hole 22, and the area surrounded by the bosses 3191 may also cover a part of the ventilation hole 22, which is not limited in the present application.
Referring to fig. 9 and 12, in other embodiments, the distance between the ventilation hole 22 and the port of the intake chamber 21 is relatively long, the portion of the end surface covering portion 31 corresponding to the ventilation hole 22 is lifted up to be insufficient for the ventilation hole 22 to communicate with the bypass port 310, so that a ventilation groove 315 may be further provided on the side of the end surface covering portion 31 facing the base 20, the ventilation groove 315 is formed by thinning a partial region on the side of the end surface covering portion 31 facing the base 20, the ventilation groove 315 communicates with the ventilation hole 22, the ventilation groove 315 extends toward the bypass port 310, and when the end surface covering portion 31 is not lifted up, the ventilation groove 315 is isolated from the bypass port 310.
Specifically, since the ventilation groove 315 communicates with the ventilation hole 22 and extends toward the avoidance port 310, the ventilation groove 315 relatively shortens the distance when the ventilation hole 22 communicates with the avoidance port 310. In other words, the pressure applied to the portion of the sealing member 30 at the ventilation hole 22 from the side of the ventilation hole 22 is guided along the ventilation groove 315 to the end of the ventilation groove 315 extending toward the avoiding opening 310, and when the pressure is greater than the pressure applied to the sealing member 30 from the side of the reservoir chamber 12, the portion of the end surface covering portion 31 at the end of the ventilation groove 315 extending toward the avoiding opening 310 is lifted up, so that the ventilation groove 315 communicates with the reservoir chamber 12 through the avoiding opening 310, and the ventilation groove 315 also reduces the local thickness of the end surface covering portion 31, so that the difficulty of lifting up the end surface covering portion 31 can be relatively reduced, and after the air pressure in the reservoir chamber 12 is raised, the lifted portion of the end surface covering portion 31 is covered on the base 20 again to isolate the reservoir chamber 12 from the ventilation groove 315.
As shown in fig. 9 and 10, the ventilation groove 315 includes a main body portion 3150 and an extension portion 3151 that communicate with each other, the main body portion 3150 is provided in correspondence with the ventilation hole 22, the main body portion 3150 may have a circular or rectangular shape, the main body portion 3150 may cover the ventilation hole 22, or the main body portion 3150 may be located in a region corresponding to the ventilation hole 22, and the extension portion 3151 extends toward the escape port 310. In other embodiments, the ventilation groove 315 may have a shape such as a linear groove, as long as it can communicate with the ventilation hole 22 and extend toward the escape port 310, and the specific shape and structure of the ventilation groove 315 is not limited in the present application.
Referring to fig. 11, in still other embodiments, a positioning pillar 316 is disposed on a side of the end surface covering portion 31 facing the base 20, the positioning pillar 316 is provided with a ventilation groove 317, the positioning pillar 316 is embedded in the ventilation hole 22, and the ventilation groove 317 communicates with the ventilation groove 315 and the ventilation hole 22.
Considering that the sealing member 30 is easy to displace and not easy to align when the base 20 is large in size and the sealing member 30 is mounted on the base 20, the positioning post 316 is further provided to cooperate with the ventilation hole 22 to position the sealing member 30, so as to avoid the sealing member 30 from deviating and reducing the sealing effect, and the positioning post 316 is provided with the ventilation groove 317 to communicate the ventilation groove 315 and the ventilation hole 22 through the ventilation groove 317, thereby ensuring that the ventilation hole 22 can communicate with the liquid storage chamber 12.
As shown in fig. 11, the venting groove 315 is disposed around the positioning post 316 and extends toward the escape opening 310.
