[0050] The upper shell 110 may include an oil cup 111, a suction nozzle 112 and an exhaust pipe 113. The oil cup 111 is roughly a hollow cylinder. The oil cup 111 and the suction nozzle 112 are connected. The exhaust pipe 113 is arranged in the oil cup 111. A liquid storage chamber 101 is formed between the exhaust pipe 113 and the oil cup 111.

The first air inlet 121 may be one or more circular holes, and the diameters of the multiple first air inlet holes 121 may be the same or different.

[0053] The bracket assembly 200 is arranged in the inner cavity surrounded by the oil cup 111 and the lower shell 120. The bracket assembly 200 includes a first inlet flow channel 201, a first end of the first inlet flow channel 201 is connected to the first inlet hole 121, and a second end of the first inlet flow channel 201 is connected to the exhaust pipe 113.

The atomizer core 300 is at least arranged on two opposite sides of the first inlet flow channel 201 and is located in the bracket assembly 200. The atomizer core 300 includes a substrate 310 and a heating element, and the heating element is arranged on one side of the substrate 310, and at least the heating element is located in the first inlet flow channel 201. When the atomizer is working, the heating element heats and atomizes the aerosol matrix, generates an aerosol in the first inlet flow channel 201, and the aerosol directly enters the exhaust pipe 113 and the suction nozzle 112 for the user to inhale.

[0054] In some atomizer designs, the atomizer core 300 is arranged directly below the exhaust pipe 113, the upper surface of the atomizer core 300 is the liquid absorption surface, and the lower surface of the atomizer core 300 is the atomization surface, and the atomization surface is provided with a heating element for heating and atomizing the aerosol matrix to generate aerosol. The inlet flow channel is arranged directly below the atomizer core 300, and the aerosol needs to bypass the atomizer core 300 from the side to enter the exhaust pipe 113 for the user to inhale, which increases the loss of aerosol in the inlet flow channel and affects the aroma and taste of the aerosol.

[0055] In this embodiment, the atomizer includes a shell assembly 100, a bracket assembly 200 and an atomizer core 300. The shell assembly 100 includes an upper shell 110 and a lower shell 120 connected to each other. The upper shell 110 may include an oil cup 111, a suction nozzle 112 and an exhaust pipe 113. The exhaust pipe 113 is arranged in the oil cup 111 and connected to the suction nozzle 112. A first air inlet hole 121 is opened on the lower shell 120. The bracket assembly 200 is arranged in an inner cavity surrounded by the oil cup 111 and the lower shell 120. The bracket assembly 200 includes a first inlet flow channel 201.

The atomizer core 300 is at least arranged on two opposite sides of the first inlet flow channel 201 and is located in the bracket assembly 200. The atomizer core 300 includes a substrate 310 and a heating element, and at least the heating element is located in the first inlet flow channel 201. The first inlet flow channel 201 is directly connected to the exhaust pipe 113. Compared with the solution in which the inlet flow channel is arranged directly below the atomizer core 300 and the aerosol needs to bypass the atomizer core 300 from the side to enter the exhaust pipe 113, the loss of aerosol in the inlet flow channel is reduced and the aroma and taste of the aerosol are improved.

[0056] In some embodiments, the first intake air passage 201 is centrally aligned with the exhaust pipe 113. That is, the center line of the first intake air passage 201 coincides with the center line of the exhaust pipe 113.

[0057] The first intake air passage 201 and the exhaust pipe 113 are centrally aligned, which can further reduce aerosol detours and reduce aerosol losses in the intake air passage.

[0058] See also Figures 4 to 6 As shown, the bracket assembly 200 includes an upper bracket 210 and a lower bracket 220 connected to each other, the upper bracket 210 includes a main body 211, and in the second direction, two opposite sides of the main body 211 are provided with accommodating holes 2111, the accommodating holes 2111 are communicated with the first inlet flow channel 201, and the atomizer core 300 is arranged in the accommodating holes 2111, and the second direction is perpendicular to the first direction. A first liquid inlet hole 2112 is provided on the side of the main body 211 away from the lower bracket 220, and the two first liquid inlet holes 2112 are located on two opposite sides of the first inlet flow channel 201, and the first liquid inlet hole 2112 communicates the liquid storage chamber 101 and the accommodating hole 2111.

[0059] The substrate 310 is provided with a heating element on one side thereof as an atomizing surface, and the side of the substrate 310 away from the heating element is a liquid absorbing surface. The substrate 310 can be made of porous materials such as porous ceramics, porous metals and porous glass to ensure that the aerosol matrix can penetrate from the liquid absorbing surface to the atomizing surface. When the atomizer is working, the aerosol matrix in the liquid storage chamber 101 can enter the containing hole 2111 through the first liquid inlet hole 2112, and then penetrate into the liquid absorbing surface of the substrate 310, and then penetrate into the atomizing surface through the substrate 310, so that the heating element can heat and atomize the aerosol matrix to generate an aerosol for the user to inhale.

[0060] The aerosol matrix penetrates into the liquid absorption surface of the substrate 310 through the first liquid inlet hole 2112 and the receiving hole 2111, which can prevent the aerosol matrix from leaking. The atomizer core 300 is arranged symmetrically on both sides to ensure that the liquid absorption surface and the atomization surface of the substrate 310 are large enough, thereby ensuring that the atomizer has sufficient atomization power.

[0061] In some embodiments, the bracket assembly 200 further includes a silicone sleeve 230 and a side bracket 240, and the side bracket 240 includes an inserting portion 241 and a connecting portion 242, and the inserting portion 241 is disposed in the receiving hole 2111. It should be noted that, Figures 4 to 6 Only one of the two silicone sleeves 230 and one of the two side brackets 240 are shown. A second liquid inlet hole 2411 is provided on the side of the inserting portion 241 close to the liquid storage chamber 101, and a third liquid inlet hole 2412 is provided on the side of the inserting portion 241 close to the base 310. The silicone sleeve 230 connects the base 310 and the inserting portion 241. A connecting hole connecting the inside and outside of the silicone sleeve 230 is provided at the position of the silicone sleeve 230 corresponding to the second liquid inlet hole 2411.

[0062] In some embodiments, the second liquid inlet hole 2411 may penetrate the insertion part 241 up and down, and the second liquid inlet hole 2411 is sealed away from the liquid storage chamber 101 by the silicone sleeve 230, so as to prevent the side bracket 240 from being installed upside down and affecting the operation of the atomizer. The connecting part 242 is a U-shaped structure, that is, the connecting part 242 includes two cantilevers with connecting arms located at both ends of the connecting arm, the cantilever is perpendicular to the connecting arm, the insertion part 241 is connected to the connecting arm of the connecting part 242, and a buckle may be provided on the cantilever of the connecting part 242, and the side bracket 240 is connected to the outer surface of the main body 211 through the buckle on the cantilever.

[0063] When the atomizer is working, the aerosol matrix in the liquid storage chamber 101 can penetrate into the liquid absorption surface of the substrate 310 through the first liquid inlet hole 2112, the second liquid inlet hole 2411, the third liquid inlet hole 2412, and the silicone sleeve 230, and then penetrate into the atomization surface through the substrate 310, so that the heating element can heat and atomize the aerosol matrix to generate an aerosol for the user to inhale.

[0064] The support assembly 200 further includes a silicone sleeve 230 and a side support 240 . The side support 240 is used for installing and positioning the atomizer core 300 , and the silicone sleeve 230 is used for sealing the liquid inlet channel to prevent leakage of the aerosol matrix.

[0065] In some embodiments, the lower bracket 220 includes a first barrel 221, a second barrel 222, and a bracket bottom plate 223. The bracket bottom plate 223 is disposed in the first barrel 221. The second barrel 222 is disposed in the first barrel 221 and is located on the side of the bracket bottom plate 223 close to the upper bracket 210. The second barrel 222 is connected to the bracket bottom plate 223. A buffer chamber 202 is formed between the first barrel 221 and the second barrel 222. The buffer chamber 202 is communicated with the first inlet air channel 201, and the accommodating hole 2111 is communicated with the buffer chamber 202.

[0066] When the atomizer is working, the aerosol matrix in the liquid storage chamber 101 is continuously consumed, and the gas pressure in the liquid storage chamber 101 decreases. Since the buffer chamber 202 connects the liquid storage chamber 101 and the first inlet flow channel 201, the outside air can enter the liquid storage chamber 101 through the first inlet flow channel 201 and the buffer chamber 202 to balance the air pressure inside and outside the liquid storage chamber 101, thereby avoiding the gas pressure in the liquid storage chamber 101 being too low, resulting in untimely supply of the aerosol matrix and affecting the user experience.

[0067] In some embodiments, the upper bracket 210 further includes a third barrel 212 and a fourth barrel 213, and the third barrel 212 and the fourth barrel 213 are both located on the side of the main body 211 away from the liquid storage chamber 101. The third barrel 212 is located in the first barrel 221, and the third barrel 212 is connected to the first barrel 221. The fourth barrel 213 is located in the third barrel 212, one end of the fourth barrel 213 is located in the second barrel 222, and a gap is formed between the fourth barrel 213 and the second barrel 222. The buffer chamber 202 is connected to the first inlet flow channel 201 through the gap between the fourth barrel 213 and the second barrel 222. A small gap is used between the second barrel 222 and the main body 211, for example, the gap between the second barrel 222 and the main body 211 is 1 mm to 5 mm.

[0068] The buffer chamber 202 is connected to the first inlet flow channel 201 through the gap between the fourth cylinder 213 and the second cylinder 222 , so as to avoid the opening of the side wall of the second cylinder 222 causing the buffer chamber 202 to have a reduced liquid storage capacity, thereby causing the aerosol matrix in the buffer chamber 202 to leak.

[0069] In some embodiments, the upper bracket 210 also includes a vent pipe 214, which is located between the third barrel 212 and the fourth barrel 213, and the vent pipe 214 is connected to the receiving hole 2111 and the buffer chamber 202. The atomizer also includes a reflux rod 400, which is arranged in the vent pipe 214, and the contact surface between the reflux rod 400 and the vent pipe 214 is provided with a reflux groove 2141 or the contact surface between the vent pipe 214 and the reflux rod 400 is provided with a reflux groove 2141, and the receiving hole 2111 is connected to the buffer chamber 202 through the reflux groove 2141. In other words, the reflux groove 2141 can be provided on the reflux rod 400, or on the inner wall of the vent pipe 214, depending on the specific situation. The manufacturing materials of the reflux rod 400 include plastic, silicone, metal, ceramic, etc. In some embodiments, the reflux rod 400 is a porous cylinder made of plastic, silicone, metal or ceramic or a cylinder made of cotton.

[0070] In order to balance the air pressure inside and outside the liquid storage chamber 101, the liquid storage chamber 101 is connected to the outside through the buffer chamber 202 and the first inlet flow channel 201, and a small amount of aerosol matrix in the liquid storage chamber 101 will leak into the buffer chamber 202. A reflux rod 400 and a reflux groove 2141 are arranged between the liquid storage chamber 101 and the buffer chamber 202. When the air pressure in the liquid storage chamber 101 decreases, the aerosol matrix in the buffer chamber 202 can slowly flow back to the liquid storage chamber 101 through the reflux rod 400 and the reflux groove 2141, which can improve the utilization rate of the aerosol matrix and reduce the risk of aerosol matrix leakage in the buffer chamber 202.

[0071] In some embodiments, a second air inlet hole 2231 is provided on the bracket bottom plate 223, a third air inlet hole 2113 is provided on the side of the main body 211 away from the liquid storage chamber 101, and the second air inlet hole 2231, the second cylinder 222, the fourth cylinder 213 and the third air inlet hole 2113 are sequentially connected to form the first inlet flow channel 201.
