As shown in fig. 1 and 2, an embodiment of the present application provides a nebulizer 100 comprising a housing 110, a reservoir 120, a nebulizing assembly 130, and a seal 140. The housing 110 includes an inlet end 112 for inlet air and an outlet end 111 for outlet air, and a first air flow channel 113 penetrating the inlet end 112 and the outlet end 111 is disposed inside the housing 110. A reservoir 120 is provided within the housing 110 for storing an aerosol-generating substrate. An atomizing assembly 130 is disposed in the first airflow channel 113 and is in fluid communication with the reservoir 120 for atomizing the aerosol-generating substrate. Seal 140 has a seal body 141 and an air relief valve 142, and seal body 141 is used to form a seal between housing 110 and atomization assembly 130, enhancing the air tightness of the assembly of atomization assembly 130 with housing 110. The gulp valve 142 is a one-way valve, and the gulp valve 142 includes a first side 1421 and a second side 1422 opposite to each other, the first side 1421 is communicated with the liquid storage chamber 120, and the second side 1422 is directly or indirectly communicated with the external air.

In the using process of the atomizer 100, when the external air pressure of the second side 1422 is greater than the internal pressure of the liquid storage cavity 120 of the first side 1421, and the pressure difference reaches a threshold value capable of pushing the air compensating valve 142 to rotate, the air compensating valve 142 is opened, the external air enters the liquid storage cavity 120 through the air compensating valve 142 to supplement the air pressure in the liquid storage cavity 120, the situation that the internal air pressure of the liquid storage cavity 120 is too low and the liquid cannot permeate into the atomizing assembly 130 for atomization is avoided, the smoothness of atomization is improved, and the situation that the atomizing assembly 130 is overheated due to dry burning caused by unsmooth liquid supply is avoided. It should be noted that the air-replenishing valve 142 is a one-way valve, and under normal conditions, the pressure inside the liquid storage chamber 120 is greater than or equal to the pressure of the external air, the liquid supply from the liquid storage chamber 120 is smooth, and the air-replenishing valve 142 is in a closed state, so as to prevent the aerosol-generating substrate in the liquid storage chamber 120 from leaking from the air-replenishing valve 142.

The sealing body 141 is a sealing silicone member 144, the air release valve 142 is an elastic member 143, and the air release valve 142 and the sealing body 141 are integrally formed, so that the assembly of the sealing body 141 and the atomizing assembly 130 is more convenient.

Specifically, when the external air pressure on the second side 1422 of the gulp valve 142 is 200 to 2000pa stronger than the internal pressure of the liquid storage chamber 120 on the first side 1421 of the gulp valve 142, the gulp valve 142 is opened, for example, 200pa, 600pa, 1000pa, 1500pa, or 2000 pa. Preferably, when the external air pressure on the second side 1422 of the gulp valve 142 is 600 to 1500pa stronger than the internal pressure of the liquid storage chamber 120 on the first side 1421 of the gulp valve 142, the gulp valve 142 is opened, such as 600pa, 900pa, 1000pa, or 1500 pa.

In one embodiment, as shown in fig. 2 to 4, the atomizing assembly 130 includes an atomizing base 131, and a groove 1315 is formed on an outer wall of the atomizing base 131, and the groove 1315 is in communication with the external air and extends to the liquid storage chamber 120, so that the external air can enter the liquid storage chamber 120. The sealing body 141 is a sealing silicone member 144, and the sealing silicone member 144 is sleeved outside the atomizing base 131. A ventilation channel 150 for external air to enter the liquid storage chamber 120 is formed between the sealing silicone member 144 and the groove 1315, and an end of the ventilation channel 150 facing the liquid storage chamber 120 is an air outlet 151. The elastic element 143 is located on the atomizing base 131 facing the liquid storage chamber 120 and covers the air outlet 151. The elastic member 143 includes a first end 1431 connected to the sealing silicone member 144 and a second end 1432 opposite to the first end 1431, and when the pressure of the side of the elastic member 143 facing away from the reservoir 120 is higher than the pressure of the side facing the reservoir 120 and the pressure difference reaches a threshold value capable of pushing the elastic member 143 to rotate, the second end 1432 of the elastic member 143 rotates towards the reservoir 120, so that the external air can enter the reservoir 120 from the air outlet 151.

In one embodiment, as shown in fig. 2, the atomizing assembly 130 further includes an atomizing element 132 and an atomizing chamber 133, the atomizing element 132 is mounted on the atomizing base 131, the atomizing chamber 133 is disposed in the atomizing element 132, and the atomizing element 132 atomizes the aerosol-generating substrate stored in the reservoir 120 in the atomizing chamber 133.

The elastic member 143 may be disposed in various ways, and the elastic member 143 may be disposed perpendicular to the central axis of the atomizer 100, or the elastic member 143 may be disposed parallel to the central axis of the atomizer 100. In one embodiment, as shown in fig. 4, the air outlet 151 is located at the top of the atomizing base 131, i.e. the side of the atomizing base 131 facing the liquid storage chamber 120, and the plane of the air outlet 151 is perpendicular to the central axis of the atomizer 100. In a natural state, the elastic member 143 is horizontally attached to the top of the atomizing base 131 at the air outlet 151, the width of the elastic member 143 is greater than that of the air outlet 151, and the elastic member 143 is attached to the top of the atomizing base 131. When the pressure of the external air in the ventilation channel 150 is greater than the pressure in the liquid storage chamber 120 and the pressure difference reaches a threshold value that can push the elastic member 143 to rotate, the elastic member 143 rotates upward, and the external air in the ventilation channel 150 passes through the air outlet 151 and enters the liquid storage chamber 120 upward to supplement the air pressure in the liquid storage chamber 120. When the pressure in the liquid storage chamber 120 is greater than or equal to the external pressure in the ventilation channel 150, the elastic member 143 is tightly attached to the air outlet 151 at the top of the atomizing base 131 under the action of the air pressure from top to bottom, so as to prevent the aerosol-generating substrate in the liquid storage chamber 120 from leaking.

In order to control the elastic force range of the elastic member 143, so that the elastic member is more easily rotated upward when the pressure of the external air inside and outside the ventilation channel 150 is greater than the pressure inside the liquid storage chamber 120, as shown in fig. 3, the thickness of the first end 1431 of the elastic member 143 is smaller than the thickness of the second end 1432 of the elastic member 143, and the width of the first end 1431 of the elastic member 143 is smaller than the width of the second end 1432 of the elastic member 143, so that the elastic member 143 can more sensitively sense the pressure change on both sides thereof, and when the pressure inside the liquid storage chamber 120 is insufficient, the elastic member is more easily rotated to one side of the liquid storage chamber 120 to timely supplement the external air inside. Specifically, the elastic force range of the elastic member 143 can be comprehensively considered in accordance with the density of the aerosol-generating substrate in the reservoir 120, the liquid absorption capacity of the atomizing assembly 130, and the like, and the thickness and width of the first end 1431 of the elastic member 143 can be adjusted to be appropriate.

Referring to fig. 5 to 7, fig. 5 is a schematic cross-sectional view of another embodiment of an atomizer according to the present application; FIG. 6 is an enlarged schematic view of portion B of FIG. 5; fig. 7 is a schematic view of a partial explosion configuration of yet another embodiment of the atomizer of the present application.

In this embodiment, the structure of the atomizer 100 and the path of the external air entering the liquid storage chamber 120 are substantially the same as those of the above-mentioned embodiment shown in fig. 1 to 3, as shown in fig. 5 to 7, the air outlet 151 is located at the top of the atomizing base 131, and in a natural state, the elastic member 143 is horizontally attached to the top of the atomizing base 131 at the air outlet 151. Except that, since the elastic member 143 is a rubber elastic member, the nebulizer 100 further includes a stopper to limit the magnitude of opening of the elastic member 143. Specifically, the blocking portion 160 includes a first step surface 114 disposed on an inner wall of the housing 110, the first step surface 114 abuts against an upper surface of a first end 1431 of the elastic member 143, and the first end 1431 of the elastic member 143 is located between the atomizing base 131 and the first step surface 114. Because the elastic component 143 is the elastic material, for example, the silica gel material, the condition of sticking up the limit appears easily in the elastic component 143, and the first end 1431 of the elastic component 143 of this application is located between atomizing seat 131 and the first step face 114, the first end 1431 of the elastic component 143 can be pushed down to first step face 114, it can not influence the rotation in the liquid storage cavity 120 of the elastic component 143, and simultaneously, can play certain limiting effect to the opening range of the elastic component 143, avoid the elastic component 143 to rotate excessively in the vertical direction, thereby prevent the elastic component 143 from appearing warping, the condition of sticking up the limit. Further, the first step surface 114 can improve the installation convenience of the sealing silicone piece 144, and facilitate the quick positioning and installation of the sealing silicone piece 144.

In addition, the elastic member 143 is easily displaced in the horizontal direction after being installed, so that the elastic member 143 cannot completely cover the air outlet 151, and the sealing function of the elastic member 143 is deteriorated. Thus, as shown in fig. 5, the top of the atomizing base 131 is provided with a supporting portion 1313, the middle of the supporting portion 1313 is recessed to form an accommodating cavity 1314 for accommodating the elastic member 143, the accommodating cavity 1314 serves to limit the elastic member 143, so as to prevent the elastic member 143 from shifting in the horizontal direction and maintain the sealing effect of the elastic member 143.

Further, the width of the receiving chamber 1314 is greater than the width of the elastic member 143, that is, a certain gap is left between the support 1313 and the elastic member 143, so that friction between the support 1313 and the elastic member 143 can be avoided, and the elastic member 143 can smoothly rotate towards the liquid storage chamber 120 when the pressure of the external gas inside and outside the ventilation channel 150 is greater than the pressure inside the liquid storage chamber 120.

Referring to fig. 8 to 12, fig. 8 is a schematic cross-sectional view of another embodiment of an atomizer according to the present application; FIG. 9 is a schematic view of a partial explosion configuration of yet another embodiment of the atomizer of the present application; FIG. 10 is a schematic illustration in partial cross-section of yet another embodiment of an atomizer according to the present application; FIG. 11 is a schematic view of the overall configuration of an atomizing base of an embodiment of an atomizer according to the present application; fig. 12 is an overall structural diagram of another perspective view of an atomizing base according to an embodiment of the atomizer of the present application.

In this embodiment, the structure of the atomizer 100 and the path of the external air entering the liquid storage chamber 120 are substantially the same as those of the above-mentioned embodiment shown in fig. 1 to 5, except that the elastic member 143 is disposed parallel to the central axis of the atomizer 100, specifically, as shown in fig. 8 to 11, the air outlet 151 is vertically disposed inside the atomizing base 131; in a natural state, the elastic member 143 is vertically attached to the inner wall of the atomizing base 131 at the air outlet 151.

Specifically, as shown in fig. 8 and 11, the atomizing base 131 has a vertical groove 1311 opened toward the inside of the atomizing base 131 along the central axis direction thereof, the top of the vertical groove 1311 is communicated with the reservoir 120, the vertical groove 1311 includes a first sidewall 1312 and a second sidewall 1313 opposite to the first sidewall 1312, and the air outlet 151 of the air exchange channel 150 is located on the first sidewall 1312. When the pressure of the external air in the ventilation channel 150 is higher than the pressure in the liquid storage chamber 120 and the pressure difference reaches a threshold value capable of pushing the elastic member 143 to rotate, the elastic member 143 rotates towards the vertical groove 1311, and the external air in the ventilation channel 150 enters the vertical groove 1311 through the air outlet 151 and then enters the liquid storage chamber 120 to supplement the air pressure in the liquid storage chamber 120. When the pressure in the reservoir 120 is greater than or equal to the external pressure in the ventilation channel 150, the resilient member 143 is tightly attached to the outlet 151 of the vertical channel 1311 under the action of the high pressure in the reservoir 120, thereby preventing the aerosol-generating substrate in the reservoir 120 from leaking.

Because the elastic member 143 is located in the vertical groove 1311, the vertical groove 1311 can limit the elastic member 143, so as to prevent the elastic member 143 from deviating and not completely covering the air outlet 151, thereby maintaining the sealing function of the elastic member 143. Further, the blocking portion 160 in this embodiment is the second sidewall 1313, and since the elastic member 143 is attached to the first sidewall 1312, a distance between the first sidewall 1312 and the second sidewall 1313 is greater than a thickness of the elastic member 143 and less than a length of the elastic member 143. The rotation amplitude of the elastic member 143 towards the second side wall 1313 is related to the pressure difference between the external air in the ventilation channel 150 and the internal air in the liquid storage chamber 120, the larger the pressure difference is, the larger the rotation amplitude of the elastic member 143 is, and the second side wall 1313 can play a certain role in limiting the opening range of the elastic member 143, so that the elastic member 143 is prevented from rotating excessively in the vertical direction, and the elastic member 143 is prevented from deforming and warping.

It should be noted that the distance between the first sidewall 1312 and the second sidewall 1313 can be adjusted according to the elastic capacity of the elastic element 143 and the length from the first end 1431 to the second end 1432 of the elastic element 143, so that the elastic element 143 can rotate towards the second sidewall 1313 to allow external air to enter the vertical groove 1311 through the air outlet 151, and excessive rotation of the elastic element 143 in the vertical direction is avoided, thereby preventing the elastic element 143 from deforming and warping.

In one embodiment, the ventilation channel 150 communicates with the nebulizing chamber 133. Specifically, as shown in fig. 11 and 12, the outer wall of the atomizing base 131 is provided with a plurality of fins 1316, the plurality of fins 1316 are arranged in parallel at intervals, transverse capillary grooves 1317 are formed between adjacent fins 1316, and the atomizing base 131 is further provided with at least one longitudinal vent groove 1318, and the longitudinal vent groove 1318 is communicated with each transverse capillary groove 1317. The atomizing base 131 is provided with at least one vent 1319 in communication with the atomizing chamber 133. The lateral capillary grooves 1317 have a function of liquid absorption and air ventilation.

The gas in the nebulizing chamber 133 enters the lateral capillary groove 1317 or the longitudinal vent groove 1318 from the vent hole 1319, then converges to the ventilation channel 150, and enters the reservoir chamber 120 through the outlet 151 opened by the air replenishment valve 142 to replenish the pressure in the reservoir chamber 120.

When liquid may overflow from the air outlet 151 at the top of the atomizing base 131 during the opening and closing of the air compensating valve 142, the transverse capillary groove can absorb the overflowing liquid and lock the liquid.

In other embodiments, the ventilation channel 150 may be directly connected to the external atmosphere, for example, by providing a ventilation port on the housing 110, the ventilation channel 150 is directly connected to the external atmosphere by being connected to the ventilation port, and the external air enters the ventilation channel 150 through the ventilation port and then enters the reservoir 120 through the air outlet 151 opened by the air compensation valve 142 to supplement the pressure in the reservoir 120.

Of course, in other embodiments, the ventilation channel 150 may be in communication with the nebulizing chamber 133 and, at the same time, in direct communication with the outside atmosphere to achieve a supplemental pressure to the reservoir chamber 120.

It should be noted that the specific details of the communication between the external air and the reservoir 120 are also applicable to any of the above embodiments. Referring to fig. 13, fig. 13 is a schematic perspective view of an electronic atomization device according to an embodiment of the present disclosure.
