[0031] The atomizer provided in this application includes: a liquid storage chamber storing a liquid matrix; a liquid storage block for absorbing and storing the liquid matrix, the liquid storage block having a receiving chamber; a partition plate disposed between the liquid storage chamber and the liquid storage block to control the speed at which the liquid matrix flows into the liquid storage block; and an atomizing assembly, at least part of which is disposed in the receiving chamber of the liquid storage block and in contact with the liquid storage block to atomize the liquid matrix and generate an aerosol. The partition plate is disposed between the liquid storage chamber and the liquid storage block to control the speed at which the liquid matrix flows into the liquid storage block, thereby preventing the liquid storage block and the atomizing assembly from absorbing the liquid matrix excessively, thereby preventing the liquid matrix from leaking.

[0032] Please refer to Figure 1, which is an exploded view of an embodiment of the atomizer provided herein. The atomizer 100 may include, but is not limited to, a main housing 110, a liquid reservoir 120, a separator 130, an atomizer assembly 140, a seal 150, a base 160, a positive electrode 171, and a negative electrode 172. The main housing 110 provides support for the other components of the atomizer 100. The liquid reservoir 120 is used to absorb and store liquid matrix. The separator 130 is used to conduct and lock the liquid matrix to control the rate at which the liquid matrix flows into the liquid reservoir 120. The atomizer assembly 140 is used to atomize the liquid matrix and generate an aerosol for inhalation by the user. The seal 150 is used to seal the space in contact with the liquid matrix and provide support for the liquid reservoir 120 and atomizer assembly 140. The base 160 is used to provide support for the seal 150. The positive electrode 171 and the negative electrode 172 provide operating power to the atomizer assembly 140.

[0033] Please refer to Figures 1, 2, 3, 4, 7, and 8. Figure 2 is a front cross-sectional view of one embodiment of the atomizer provided herein. Figure 3 is a front cross-sectional view of another embodiment of the atomizer provided herein. Figure 4 is a side cross-sectional view of one embodiment of the atomizer provided herein. Figure 7 is a cross-sectional view of one embodiment of the main housing provided herein. Figure 8 is a cross-sectional view of one embodiment of the base provided herein. The main housing 110 may include, but is not limited to, a first wall 111 and a second wall 112. The second wall 112 is fixed to the first wall 111. As shown in Figure 7, the outer side of the second wall 112 and the inner side of the first wall 111 form a receiving groove 103. The inner side of the second wall 112 forms a ventilation channel 1121 as shown in Figure 4. An air outlet 102 is provided at the junction of the first wall 111 and the second wall 112 to release the generated aerosol. The position of the air outlet 102 relative to the atomizer 100 is defined as the upper side, top, or tip. The isolation plate 130 is secured to the receiving groove 103. The upper surfaces of the receiving groove 103 and the isolation plate 130 define a liquid storage chamber 101. The liquid storage chamber 101 stores a liquid matrix 180. When heated, the liquid matrix 180 mixes with air to form an aerosol. The portion of the main housing 110 corresponding to the liquid storage chamber 101 is transparent, allowing the user to readily see the remaining liquid matrix 180 in the liquid storage chamber 101. This prevents the liquid matrix 180 from running out and causing a burnt taste in the inhaled liquid, which could negatively impact the user experience.

[0034] Furthermore, the main housing 110 is provided with a stepped groove 104 at the notch of the receiving groove 103. The stepped groove 104 includes a first positioning groove 1041 and a second positioning groove 1042 that communicate with each other. The isolation plate 130 is disposed through the end of the second wall 112 away from the air outlet 102 and is fixed to the first positioning groove 1041. The liquid storage block 120 is disposed through the atomizer assembly 140 and is fixed to the second positioning groove 1042.

[0035] Optionally, the first wall 111 and the second wall 112 may be integrally formed. The main housing 110 may be made of plastic.

[0036] Furthermore, one end of the second wall 112 away from the air outlet 102 is inserted into the atomizer assembly 140 to position and install the atomizer assembly 140 and at the same time make the ventilation channel 1121 directly connected to the atomizer assembly 140. Among them, at least part of the outer side surface of the second wall 112 is closely attached to the atomizer assembly 140 to fix the atomizer assembly 140. The liquid storage block 120 is clamped between the inner side surface of the first wall 111 and the atomizer assembly 140, and the partial structure connecting the atomizer assembly 140 and the second wall 112 is pressed against the outer side surface of the second wall 112. The liquid storage block 120 is used to absorb and store the liquid matrix 180. The liquid storage block 120 has a accommodating cavity 121. At least part of the structure of the atomizer assembly 140 is arranged in the accommodating cavity 121 of the liquid storage block 120 and contacts the liquid storage block 120 to atomize the liquid matrix 180 and generate an aerosol. The isolation plate 130 is disposed between the liquid reservoir 101 and the liquid reservoir block 120. Due to the barrier provided by the isolation plate 130, the liquid matrix 180 in the liquid reservoir 101 can enter the liquid reservoir block 120 more slowly. This controls the flow rate of the liquid matrix 180 into the liquid reservoir block 120, thereby preventing the liquid reservoir block 120 and the atomizer assembly 140 from being oversaturated with the liquid matrix 180 and causing leakage of the liquid matrix 140. The liquid matrix 180 flows from the liquid reservoir 101 through the isolation plate 130 into the liquid reservoir block 120, and then from the liquid reservoir block 120 into the atomizer assembly 140, where it is atomized by the atomizer assembly 140 to generate an aerosol.

[0037] Optionally, the material of the isolation plate 130 may include polyethylene terephthalate to better control the speed at which the liquid matrix 180 flows into the liquid storage block 120 .

[0038] Optionally, the density of the separator 130 can be 0.2-0.5 grams per cubic centimeter, so that the separator 130 has both good liquid-conducting and liquid-retaining properties to achieve a desired liquid-draining speed. Specifically, the density of the separator 130 can be 0.21 g / cm^3, 0.23 g / cm^3, 0.25 g / cm^3, 0.30 g / cm^3, 0.35 g / cm^3, 0.40 g / cm^3, 0.45 g / cm^3, etc.

[0039] It is understandable that the isolation plate 130 is required to have both liquid-conducting properties to conduct the liquid matrix 180 to the liquid reservoir 120 and liquid-locking properties to lock the liquid matrix 180 and limit the speed at which the liquid matrix 180 flows to the liquid reservoir 120. A suitable density corresponds to a suitable porosity, which enables the isolation plate 130 to have both good liquid-conducting and liquid-locking properties.

[0040] Optionally, the material of the liquid storage block 120 can be polyamide and polyethylene terephthalate to obtain good liquid absorption and liquid storage performance. Alternatively, the material of the liquid storage block 120 can be polyethylene and polypropylene to obtain good liquid absorption and liquid storage performance.

[0041] Furthermore, a sealing member 150 is disposed at the bottom of the receiving tank 103. The sealing member 150 is provided with a through hole 151. At least a portion of the structure of the atomizer assembly 140 passes through the through hole 151. The sealing member 150 is fixed to the main housing 110. Specifically, the sealing member 150 is clamped between the main housing 110 and the atomizer assembly 140. The end surface of the sealing member 150 facing the liquid reservoir block 120 contacts the liquid reservoir block 120 to provide support for the liquid reservoir block 120.

[0042] Optionally, the sealing member 150 may be made of silicone to achieve good sealing performance.

[0043] Furthermore, the base 160 is snapped onto the main shell 110. Specifically, the base 160 is provided with a first snap-on structure (not shown), and the first wall 111 in the main shell 110 is provided with a second snap-on structure (not shown). The first snap-on structure and the second snap-on structure cooperate so that the base 160 is snapped onto the main shell 110. In one embodiment, the first snap-on structure can be a protrusion, and the second snap-on structure can be a groove. The base 160 is provided with an avoidance hole 162 and an air inlet 161. The position of the air inlet 161 relative to the atomizer 100 is defined as the lower side or bottom or bottom end. The avoidance hole 162 is used for the positive electrode 171 and the negative electrode 172 to pass through. In one embodiment, the positive electrode 171 and / or the negative electrode 172 are interference-fitted with the avoidance hole 162 to fix the positive electrode 171 and / or the negative electrode 172 on the base 160. The air inlet 161 is used for air to flow into the atomization assembly 140. The atomizer assembly 140 is disposed between the air inlet 161 and the air outlet 102. A vent 1121 is defined between the air outlet 102 and an end of the atomizer assembly 140 adjacent to the air outlet 102. The interior of the atomizer assembly 140 communicates with the vent 1121 to release aerosol into the air outlet 102. Optionally, the base 160 may be made of plastic.

[0044] Please refer to Figures 1, 2, 3, 5, and 6 in conjunction with each other. Figure 5 is an exploded schematic diagram of an embodiment of the atomizer assembly provided in this application, and Figure 6 is a cross-sectional view of an embodiment of the atomizer assembly provided in this application. The atomizer assembly 140 may include, but is not limited to, a mounting tube 141, a porous body 142, a heating element 143, and a support member 144. The mounting tube 141 is provided with a liquid guide hole 1411, so that the liquid matrix in the liquid storage block 120 can be absorbed by the porous body 142 through the liquid guide hole 1411. The porous body 142 is arranged in the mounting tube 141 corresponding to the liquid guide hole 1411 to absorb and store the liquid matrix. The porous body 142 is provided with an atomization space 1421 connected to the ventilation channel 1121 and the air inlet 161 to atomize the liquid matrix to generate an aerosol and release the aerosol. The heating element 143 is embedded in the porous body 142 and is in contact with it and arranged adjacent to the atomization space 1421 to heat the liquid matrix 180 and generate an aerosol. Support member 144 is secured within the end of tube 141 away from air outlet 102. Referring to Figure 6 , support member 144 is provided with a through-hole 1441 for airflow. Support member 144 is also provided with a through-slot 1442 around its periphery to guide and secure the positive and negative leads of heating element 143. Specifically, through-slot 1442 positions the positive and negative leads of heating element 143, preventing them from shifting.

[0045] Optionally, the porous body 142 may be made of cotton to improve the taste of the aerosol.

[0046] Optionally, the support member 144 may be made of polycarbonate or glass fiber. In one embodiment, the support member 144 is chamfered at one end facing the porous body 142 to facilitate insertion into the tube 141 .

[0047] Optionally, the heating element 143 may be a grid-shaped heating net. The material of the heating element 143 may be iron-chromium-aluminum or nickel-chromium alloy.

[0048] Furthermore, heating element 143 includes a positive lead 1431 and a negative lead 1432. Positive lead 1431 and negative lead 1432 are inserted through through-hole 151. Positive electrode 171 passes through one escape hole 162 and is in pressurized contact with positive lead 1431, while negative electrode 172 passes through another escape hole 162 and is in pressurized contact with negative lead 1432, ensuring more reliable electrical conductivity.

[0049] When the user inhales at the air outlet 102, the outside air enters the atomization space 1421 through the through hole 1441 from the air inlet 161, and generates an aerosol with the liquid matrix 180 under the heating of the heating element 143; the aerosol enters the ventilation channel 1121 from the atomization space 1421, and is then released at the air outlet 102 and inhaled by the user.

[0050] The atomizer 100 provided herein includes: a liquid storage chamber 101 storing a liquid matrix 180; a liquid storage block 120 for absorbing and storing the liquid matrix 180, the liquid storage block 120 having a receiving chamber 121; a partition plate 130 disposed between the liquid storage chamber 101 and the liquid storage block 120 to control the flow rate of the liquid matrix 180 into the liquid storage block 120; and an atomizer assembly 140, at least partially disposed within the receiving chamber 121 of the liquid storage block 120 and in contact with the liquid storage block 120 to atomize the liquid matrix 180 and generate an aerosol. The partition plate 130 is disposed between the liquid storage chamber 101 and the liquid storage block 120 to control the flow rate of the liquid matrix 180 into the liquid storage block 120, thereby preventing the liquid storage block 120 and the atomizer assembly 140 from being oversaturated with the liquid matrix 180 and causing leakage of the liquid matrix 180.

In other embodiments, the atomizer 100 can also be fixed in the outer shell 200 by means of mechanical connections such as magnetic attraction, threaded connection, and snap connection, so that the user can replace the atomizer 100 or the power supply assembly 300; the atomizer 100 and the power supply assembly 300 can also be designed as an integrated unit, and replacement is not allowed. No specific restrictions are made here. The power supply assembly 300 is disposed in the space enclosed by the outer shell 200 and the atomizer 100, and is electrically connected to the atomizer 100 to provide working power to the atomizer 100.
