[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] See also Figures 1 to 4 , Figure 1 This is a schematic diagram of the three-dimensional structure of an embodiment of the atomizer of the present application; Figure 2 1 is a schematic cross-sectional view of an embodiment of an atomizer of the present application; Figure 3 yes Figure 2 A magnified schematic diagram of part A; Figure 4 It is a schematic diagram of the partial explosion structure of an embodiment of the atomizer of the present application.

[0038] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a nebulizer 100, which includes a housing 110, a liquid storage chamber 120, an atomizing assembly 130 and a sealing member 140. The housing 110 includes an air inlet end 112 for air intake and an air outlet end 111 for air discharge, and a first air flow channel 113 is provided inside the housing 110, which passes through the air inlet end 112 and the air outlet end 111. The liquid storage chamber 120 is arranged in the housing 110 for storing an aerosol-generating matrix. The atomizing assembly 130 is arranged in the first air flow channel 113 and is in fluid communication with the liquid storage chamber 120 to atomize the aerosol-generating matrix. The sealing member 140 has a sealing member body 141 and an air supply valve 142. The sealing member body 141 is used to form a seal between the housing 110 and the atomizing assembly 130, thereby enhancing the air tightness of the assembly of the atomizing assembly 130 and the housing 110. The air supply valve 142 is a one-way valve and includes a first side 1421 and a second side 1422 that are oppositely disposed. The first side 1421 communicates with the liquid storage chamber 120 , and the second side 1422 communicates directly or indirectly with external air.

[0039] During use of the above-mentioned atomizer 100, when the external gas pressure on the second side 1422 is greater than the pressure in the liquid storage chamber 120 on the first side 1421, and the pressure difference reaches a threshold value that can drive the air supply valve 142 to rotate, the air supply valve 142 opens, and the external gas enters the liquid storage chamber 120 through the air supply valve 142 to replenish the air pressure in the liquid storage chamber 120, thereby preventing the air pressure in the liquid storage chamber 120 from being too low and the liquid from being unable to penetrate the atomizing assembly 130 for atomization, thereby improving the smoothness of the atomization liquid supply, and avoiding the situation where the atomizing assembly 130 is dry-burned and overheated due to poor liquid supply. It should be noted that the air supply valve 142 is a one-way valve. Under normal circumstances, the pressure in the liquid storage chamber 120 is greater than or equal to the pressure of the external gas, the liquid supply in the liquid storage chamber 120 is smooth, and the air supply valve 142 is in a closed state, preventing the aerosol-generating matrix in the liquid storage chamber 120 from leaking from the air supply valve 142.

[0040] The sealing body 141 is a sealing silicone member 144 , the air supply valve 142 is an elastic member 143 , and the air supply valve 142 and the sealing body 141 are integrally formed, so that the sealing body 141 and the atomizing assembly 130 are more convenient to assemble.

[0041] Specifically, the air supply valve 142 opens when the pressure of the external gas on the second side 1422 of the air supply valve 142 is 200-2000 Pa higher than the pressure in the liquid storage chamber 120 on the first side 1421 of the air supply valve 142, for example, 200 Pa, 600 Pa, 1000 Pa, 1500 Pa, or 2000 Pa. Preferably, the air supply valve 142 opens when the pressure of the external gas on the second side 1422 of the air supply valve 142 is 600-1500 Pa higher than the pressure in the liquid storage chamber 120 on the first side 1421 of the air supply valve 142, for example, 600 Pa, 900 Pa, 1000 Pa, or 1500 Pa.

[0042] In one embodiment, if Figures 2 to 4 As shown, the atomizer assembly 130 includes an atomizer seat 131, and the outer wall of the atomizer seat 131 is provided with a groove 1315. The groove 1315 is connected to the external gas and extends to the liquid storage chamber 120 to allow external gas to enter the liquid storage chamber 120. The sealing body 141 is a sealing silicone member 144, which is sleeved on the outside of the atomizer seat 131. A ventilation channel 150 for external gas to enter the liquid storage chamber 120 is formed between the sealing silicone member 144 and the groove 1315. The end of the ventilation channel 150 facing the liquid storage chamber 120 is an air outlet 151. The elastic member 143 is located on the side of the atomizer seat 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. When the pressure on the side of the elastic member 143 facing away from the liquid storage chamber 120 is greater than the pressure on the side facing the liquid storage chamber 120, and the pressure difference reaches a threshold that can push the elastic member 143 to rotate, the second end 1432 of the elastic member 143 rotates toward the liquid storage chamber 120, so that external gas can enter the liquid storage chamber 120 from the air outlet 151.

[0043] In one embodiment, if Figure 2 As shown, the atomizing assembly 130 further includes an atomizing element 132 and an atomizing chamber 133 . The atomizing element 132 is mounted on the atomizing seat 131 , and the atomizing chamber 133 is disposed within the atomizing element 132 . The atomizing element 132 atomizes the aerosol-generating matrix stored in the liquid storage chamber 120 in the atomizing chamber 133 .

[0044] The elastic member 143 can be arranged in a variety of ways. The elastic member 143 can be arranged perpendicular to the central axis of the atomizer 100, or the elastic member 143 can be arranged parallel to the central axis of the atomizer 100. In one embodiment, Figure 4As shown, the air outlet 151 is located at the top of the atomizer seat 131, that is, the atomizer seat 131 is facing the side of the liquid storage chamber 120, and the plane where the air outlet 151 is located 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 atomizer seat 131 at the air outlet 151, the width of the elastic member 143 is greater than the width of the air outlet 151, and the elastic member 143 is attached to the top of the atomizer seat 131. When the pressure of the external gas 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 drive the elastic member 143 to rotate, the elastic member 143 rotates upward, and the external gas in the ventilation channel 150 passes through the air outlet 151 and enters the liquid storage chamber 120 upward to replenish 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 fitted to the air outlet 151 at the top of the atomizer seat 131 under the action of the air pressure from top to bottom, preventing the aerosol-generating matrix in the liquid storage chamber 120 from leaking.

[0045] In order to control the elastic force range of the elastic member 143, it is easier to rotate upward when the pressure of the external gas in the ventilation channel 150 is greater than the pressure in the liquid storage chamber 120. Figure 3 As shown, the thickness of the first end 1431 of the elastic member 143 is less 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 less than the width of the second end 1432 of the elastic member 143. As a result, the elastic member 143 is more sensitive to pressure changes on both sides of it. When the pressure in the liquid storage chamber 120 is insufficient, it is easier to rotate toward the liquid storage chamber 120, thereby promptly replenishing the liquid storage chamber 120 with external gas. Specifically, the elastic force range of the elastic member 143 can be comprehensively considered based on the density of the aerosol-generating substrate in the liquid storage chamber 120, the liquid absorption capacity of the atomizer assembly 130, and other factors, and then the thickness and width of the first end 1431 of the elastic member 143 can be adjusted to achieve an appropriate elastic force range.

[0046] See also Figures 5 to 7 , Figure 5 1 is a schematic cross-sectional view of another embodiment of the atomizer of the present application; Figure 6 yes Figure 5 An enlarged schematic diagram of part B; Figure 7 This is a schematic diagram of the partial explosion structure of another embodiment of the atomizer of the present application.

[0047] In this embodiment, the structure of the atomizer 100 and the path of the external gas entering the liquid storage chamber 120 are the same as those described above. Figures 1 to 3 The embodiments shown are substantially the same as Figures 5 to 7As shown, the air outlet 151 is located at the top of the atomizer seat 131. In the natural state, the elastic member 143 is horizontally attached to the top of the atomizer seat 131 at the air outlet 151. The difference is that since the elastic member 143 is a rubber elastic member, the atomizer 100 further includes a blocking portion to limit the opening range of the elastic member 143. Specifically, the blocking portion 160 includes a first stepped surface 114 provided on the inner wall of the housing 110. The first stepped surface 114 is provided to abut the upper surface of the first end 1431 of the elastic member 143. The first end 1431 of the elastic member 143 is located between the atomizer seat 131 and the first stepped surface 114. Since the elastic member 143 is made of an elastic material, such as silicone, the elastic member 143 is prone to warping. However, the first end 1431 of the elastic member 143 of the present application is located between the atomizer seat 131 and the first step surface 114. The first step surface 114 can press the first end 1431 of the elastic member 143, which will not affect the rotation of the elastic member 143 in the liquid storage chamber 120. At the same time, it can limit the opening range of the elastic member 143 to a certain extent, preventing the elastic member 143 from rotating excessively in the vertical direction, thereby preventing the elastic member 143 from deforming or warping. Furthermore, the first step surface 114 can improve the installation convenience of the sealing silicone member 144, facilitating the rapid positioning and installation of the sealing silicone member 144.

[0048] In addition, after installation, the elastic member 143 is prone to horizontal deviation, resulting in the elastic member 143 not being able to completely cover the air outlet 151, causing the sealing effect of the elastic member 143 to fail. Figure 5 As shown, a supporting portion 1313 is provided on the top of the atomizer seat 131. The middle part of the supporting portion 1313 is recessed to form a receiving cavity 1314 for accommodating the elastic member 143. The receiving cavity 1314 serves to limit the elastic member 143, thereby preventing the elastic member 143 from deviating in the horizontal direction and maintaining the sealing effect of the elastic member 143.

[0049] Furthermore, the width of the accommodating cavity 1314 is greater than the width of the elastic member 143, that is, a certain gap is left between the supporting portion 1313 and the elastic member 143, which can avoid friction between the supporting portion 1313 and the elastic member 143, and ensure that when the pressure of the external gas in the ventilation channel 150 is greater than the pressure in the liquid storage cavity 120, the elastic member 143 can smoothly rotate into the liquid storage cavity 120.

[0050] See also Figures 8 to 12 , Figure 8 1 is a schematic cross-sectional view of another embodiment of the atomizer of the present application; Figure 9 This is a schematic diagram of a partial explosion structure of another embodiment of the atomizer of the present application; Figure 10 This is a partial cross-sectional structural diagram of another embodiment of the atomizer of the present application; Figure 11This is a schematic diagram of the overall structure of the atomizer seat of an embodiment of the present application; Figure 12 This is a schematic diagram of the overall structure of the atomizer seat of one embodiment of the present application from another perspective.

[0051] In this embodiment, the structure of the atomizer 100 and the path of the external gas entering the liquid storage chamber 120 are the same as those described above. Figures 1 to 5 The embodiment shown is substantially the same, except that the elastic member 143 is arranged parallel to the central axis of the atomizer 100. Specifically, as shown in FIG. Figures 8 to 11 As shown, the air outlet 151 is vertically disposed inside the atomizer seat 131 ; in a natural state, the elastic member 143 is vertically attached to the inner wall of the atomizer seat 131 at the air outlet 151 .

[0052] Specifically, if Figure 8 and Figure 11 As shown, the atomizer seat 131 is provided with a vertical groove 1311 along its central axis toward the interior of the atomizer seat 131. The top of the vertical groove 1311 is in communication with the liquid storage chamber 120. The vertical groove 1311 includes a first sidewall 1312 and a second sidewall 1313 opposite the first sidewall 1312. The air outlet 151 of the ventilation channel 150 is located on the first sidewall 1312. When the pressure of the external gas 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 drive the elastic member 143 to rotate, the elastic member 143 rotates into the vertical groove 1311, and the external gas in the ventilation channel 150 enters the vertical groove 1311 through the air outlet 151, and then enters the liquid storage chamber 120 to replenish the air pressure in the liquid storage chamber 120. When the pressure inside the liquid storage chamber 120 is greater than or equal to the external pressure inside the ventilation channel 150, the elastic member 143 is tightly fitted to the air outlet 151 of the vertical groove 1311 under the action of the high pressure inside the liquid storage chamber 120, thereby preventing the aerosol-generating matrix inside the liquid storage chamber 120 from leaking.

[0053] Because the elastic member 143 is located within the vertical groove 1311, the vertical groove 1311 acts as a limiter for the elastic member 143, preventing it from shifting and failing to fully cover the air outlet 151, thereby maintaining the sealing effect of the elastic member 143. Furthermore, in this embodiment, the blocking portion 160 is a second sidewall 1313. Because the elastic member 143 is attached to the first sidewall 1312, the distance between the first sidewall 1312 and the second sidewall 1313 is greater than the thickness of the elastic member 143 and less than the length of the elastic member 143. The extent to which the elastic member 143 rotates toward the second sidewall 1313 is related to the pressure difference between the air inside and outside the ventilation channel 150 and the liquid storage chamber 120. The greater the pressure difference, the greater the extent to which the elastic member 143 rotates. The second sidewall 1313 can limit the opening range of the elastic member 143, preventing it from excessively rotating in the vertical direction, thereby preventing deformation and warping of the elastic member 143.

[0054] It should be noted that the distance between the first side wall 1312 and the second side wall 1313 can be adjusted according to the elastic capacity of the elastic member 143 and the length from the first end 1431 to the second end 1432 of the elastic member 143, so that the elastic member 143 can rotate toward the second side wall 1313 to allow external gas to enter the vertical groove 1311 through the air outlet 151, while avoiding excessive rotation of the elastic member 143 in the vertical direction, thereby preventing the elastic member 143 from deformation and warping.

[0055] In one embodiment, the ventilation channel 150 is connected to the atomization chamber 133. Specifically, Figure 11 and Figure 12 As shown, the outer wall of the atomizer seat 131 is provided with a plurality of fins 1316. The fins 1316 are arranged in parallel and spaced apart, and transverse capillary grooves 1317 are formed between adjacent fins 1316. The atomizer seat 131 also has at least one longitudinal ventilation groove 1318, which connects to each transverse capillary groove 1317. The atomizer seat 131 has at least one vent hole 1319 connected to the atomizing chamber 133. The transverse capillary grooves 1317 have the functions of liquid absorption and ventilation.

[0056] The gas in the atomization chamber 133 enters the transverse capillary groove 1317 or the longitudinal ventilation groove 1318 from the vent hole 1319 , then converges to the ventilation channel 150 , and enters the liquid storage chamber 120 through the outlet 151 opened by the air replenishment valve 142 to replenish the pressure in the liquid storage chamber 120 .

[0057] When the air supply valve 142 is opened and closed, liquid may overflow from the air outlet 151 on the top of the atomizer seat 131 , and the transverse capillary grooves can absorb the overflowed liquid and lock the liquid.

[0058] In other embodiments, the ventilation channel 150 can be directly connected to the external atmosphere, for example, by providing a ventilation port on the shell 110, and the ventilation channel 150 is connected to the ventilation port, and then directly connected to the external atmosphere. The external gas enters the ventilation channel 150 through the ventilation port, and then enters the liquid storage chamber 120 through the outlet 151 opened by the air replenishment valve 142 to replenish the pressure in the liquid storage chamber 120.

[0059] Of course, in other embodiments, the ventilation channel 150 can be connected to the atomization chamber 133 and directly connected to the external atmosphere at the same time to achieve pressure replenishment for the liquid storage chamber 120.

[0060] It should be noted that the specific details of the above-mentioned communication between the external gas and the liquid storage chamber 120 are also applicable to any of the above-mentioned embodiments. Figure 13 , Figure 13 It is a schematic diagram of the three-dimensional structure of an embodiment of the electronic atomization device of the present application.

[0061] Another embodiment of the present application provides an electronic atomization device 200, which includes a power supply assembly (not shown, located inside the electronic atomization device 200) and the atomizer 100 of any of the above embodiments. The electronic atomization device 200 also includes a power supply assembly 210 for powering the atomizer 100 so that the atomizer 100 can atomize the aerosol-generating substrate into smoke.

[0062] In summary, during use of the electronic atomization device 200 of the present application, when the external gas pressure on the second side 1422 is greater than the pressure in the liquid storage chamber 120 on the first side 1421, and the pressure difference reaches a threshold value that can drive the elastic member 143 to rotate, the air supply valve 142 opens, and the external gas enters the liquid storage chamber 120 through the air supply valve 142 to replenish the air pressure in the liquid storage chamber 120, thereby avoiding the situation where the air pressure in the liquid storage chamber 120 is too low and the liquid cannot penetrate into the atomization assembly 130 for atomization, improving the smoothness of the atomization liquid supply, and avoiding the situation where the atomization assembly 130 is dry-burned and overheated due to poor liquid supply. Under normal circumstances, the pressure in the liquid storage chamber 120 is greater than or equal to the pressure of the external gas, the liquid supply in the liquid storage chamber 120 is smooth, and the air supply valve 142 is in a closed state, preventing the aerosol-generating matrix in the liquid storage chamber 120 from leaking from the air supply valve 142.

[0063] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application.
