As shown in
During operation of the atomizer 100 described above, when a pressure of the external air on the second side 1422 is greater than a pressure in the liquid storage chamber 120 on the first side 1421, and a differential-pressure reaches a threshold which can push the air compensating valve 142 to rotate, the air compensating valve 142 is opened, the external air enters the liquid storage chamber 120 through the air compensating valve 142, to supply an air pressure in the liquid storage chamber 120, thus a situation that the air pressure in the liquid storage chamber 120 is too low can be avoided, a situation that the liquid cannot penetrate to the atomizing assembly 130 for atomization can be avoided, a fluency of atomizing liquid supply is improved, and a situation that the atomizing assembly 130 is overheated due to an unsmooth liquid supply is avoided. It should be noted that the air compensating valve 142 is a one-way valve. In a normal situation, the pressure in the liquid storage chamber 120 is greater than or equal to the pressure of the external air, the liquid storage chamber 120 supplies liquid smoothly, and the air compensating valve 142 is in a closed state, thus, the aerosol generating material inside the liquid storage chamber 120 is prevented from leaking through the air compensating valve 142.
Wherein the sealing body 141 is a sealing silicone element 144, the air compensating valve 142 is an elastic element 143. The air compensating valve 142 and the sealing body 141 are integrally formed, so that an assembly of the sealing body 141 and the atomizing assembly 130 is more convenient.
Specifically, when the pressure of the external air on the second side 1422 of the air compensating valve 142 is 200-2000 pa greater than the pressure in the liquid storage chamber 120 on the first side 1421 of the air compensating valve 142, the air compensating valve 142 is opened, such as 200 pa, 600 pa, 1000 pa, 1500 pa or 2000 pa etc. In an embodiment, when the pressure of the external air on the second side 1422 of the air compensating valve 142 is 600-1500 pa greater than the pressure in the liquid storage chamber 120 on the first side 1421 of the air compensating valve 142, the air compensating valve 142 is opened, such as 600 pa, 900 pa, 1000 pa or 1500 pa etc.
In an embodiment, as shown in
In an embodiment, as shown in
The elastic element 143 may be set in a variety of ways. The elastic element 143 may be disposed perpendicular to a central axis of the atomizer 100, or the elastic element 143 is disposed parallel to the central axis of the atomizer 100. In an embodiment, as shown in
In order to control a range of elastic force of the elastic element 143, to make it easier to rotate upward when the pressure of the external air within the air exchange passage 150 is greater than the pressure in the liquid storage chamber 120, as shown in
In this embodiment, a structure of the atomizer 100 and a path of the external air into the liquid storage chamber 120 are approximately the same as the embodiment shown in
In addition, after installation, the elastic element 143 is prone to migrate in a horizontal direction. As a result, the elastic element 143 cannot completely cover the air outlet 151, which may cause a failure of sealing function of the elastic element 143. Thus, as shown in
Further, a width of the receiving chamber 1314 is greater than a width of the elastic element 143. That is, there is an interval between the supporting part 1313 and the elastic element 143, which may avoid a friction between the supporting part 1313 and the elastic element 143, so as to ensure that the elastic element 143 rotates smoothly to the liquid storage chamber 120 when the pressure of the external air within the air exchange passage 150 is greater than the pressure in the liquid storage chamber 120.
Please refer to
In this embodiment, the structure of the atomizer 100 and the path of the external air into the liquid storage chamber 120 are approximately the same as the embodiment shown in
Specifically, as shown in
Since the elastic element 143 is disposed within the vertical groove 1311, the vertical groove 1311 may limit the elastic element 143, and avoids a migration of elastic element 143 which result in the condition that the elastic element 143 cannot completely cover the air outlet 151, so as to maintain the sealing function of the elastic element 143. Further, the blocking element 160 in this embodiment is the second side wall 1313. The elastic element 143 abuts against the first side wall 1312, a distance between the first side wall 1312 and the second side wall 1313 is greater than a thickness of the elastic element 143, and less than a length of the elastic element 143. The thickness of the elastic element 143 refers to a thickness in a direction from the first side wall 1312 to the second side wall 1313. The length of the elastic element 143 refers to a length in a direction from the first end 1431 to the second end 1432. Rotation amplitude of the elastic element 143 toward the second side wall 1313 is related to the differential-pressure between the external air within the air exchange passage 150 and the liquid storage chamber 120. The greater the differential-pressure, the greater is the rotation amplitude of the elastic element 143. The second side wall 1313 may limit the opening amplitude of the elastic element 143, to avoid an excessive rotation of the elastic element 143 in a vertical direction, so as to prevent the elastic element 143 from deforming or warping.
It should be noted that, the distance between the first side wall 1312 and the second side wall 1313 may be adjusted according to an elastic capability of the elastic element 143, and the length of the first end 1431 to the second end 1432 of the elastic element 143, so that the elastic element 143 can rotate toward the second side wall 1313 for the external air to enter the vertical groove 1311 through the air outlet 151. At the same time, the excessive rotation of the elastic element 143 in a vertical direction is avoided, so as to prevent the elastic element 143 from deforming or warping.
In an embodiment, the air exchange passage 150 communicates with the atomizing chamber 133. Specifically, as shown in
The air of the atomizing chamber 133 enters the horizontal capillary grooves 1317 or the vertical vent groove 1318 through the air vent 1319, and then converges into the air exchange passage 150, and enters the liquid storage chamber 120 through the air outlet 151 opened by the air compensating valve 142, to supply the pressure in the liquid storage chamber 120.
During the process of opening and closing of the air compensating valve 142, liquid may overflow from the air outlet 151 on the top of the atomizing base 131, and the horizontal capillary grooves can absorb the spilled liquid and lock it in.
In other embodiments, the air exchange passage 150 may communicate with the external air directly. For example, a scavenge port may be disposed on the housing 110, the air exchange passage 150 communicates with the external air directly through the scavenge port, the external air enters the air exchange passage 150 through the scavenge port, and then enters the liquid storage chamber 120 through the air outlet 151 opened by the air compensating valve 142, to supply the pressure in the liquid storage chamber 120.
Of course, in other embodiments, the air exchange passage 150 may communicate with the atomizing chamber 133, and communicate with the external air directly at the same time, to supply the pressure in the liquid storage chamber 120.
It should be noted that, the details of a communication between the external air and the liquid storage chamber 120 are also applicable in any one of the embodiments described above. Please refer to

The electronic atomizing device 200 includes a power supply assembly (the power supply assembly is disposed within the electronic atomizing device 200, and is not shown in the FIGS) and an atomizer 100 of any one of the embodiments described above. The electronic atomizing device 200 further includes the power supply assembly; the power supply assembly 210 is configured to power the atomizer 100, to enable the atomizer 100 to atomize the aerosol generating material into smoke.
In summary, during operation of the electronic atomizing device 200 of the present disclosure, when the pressure of the external air on the second side 1422 is greater than the pressure in the liquid storage chamber 120 on the first side 1421, and the differential-pressure reaches a threshold which can push the air compensating valve 142 to rotate, the air compensating valve 142 is opened, the external air enters the liquid storage chamber 120 through the air compensating valve 142, to supply the air pressure in the liquid storage chamber 120, and avoid a situation that the air pressure in the liquid storage chamber 120 being too low, liquid cannot penetrate to the atomizing assembly 130 for atomization, so as to improve a fluency of atomizing liquid supply, and avoid a situation that the atomizing assembly 130 is overheated due to an unsmooth liquid supply. In a normal situation, the pressure in the liquid storage chamber 120 is greater than or equal to the pressure of the external air, the liquid storage chamber 120 supplies liquid smoothly, and the air compensating valve 142 is in a closed state, to prevent the aerosol generating material inside the liquid storage chamber 120 from leaking from the air compensating valve 142.
