[0049] Referring to Figs. 1 to 3 As shown, the atomizer in the embodiment includes a shell assembly 100, a support assembly 200, and an atomizing core 300. The shell assembly 100 includes an upper shell 110 and a lower shell 120 connected together, and the upper shell 110 and the lower shell 120 are detachably connected through a buckle structure.

[0050] The upper shell 110 can include an oil cup 111, a suction nozzle 112, and an exhaust pipe 113. The oil cup 111 is generally a hollow cylinder, the oil cup 111 and the suction nozzle 112 are connected, and the exhaust pipe 113 is arranged in the oil cup 111. The exhaust pipe 113 and the oil cup 111 form a liquid storage cavity 101 therebetween, and the liquid storage cavity 101 is used to store an aerosol substrate.

In some embodiments, the upper shell 110 can further include a connecting pipe 114 which is integrally connected with the oil cup 111, and the connecting pipe 114 is inserted into the lower shell 120 to achieve the connection of the upper shell 110 and the lower shell 120. The outer wall of the connecting pipe 114 can be further provided with a buckle, and the inner wall of the lower shell 120 can be further provided with a clamping groove to achieve the detachable connection of the upper shell 110 and the lower shell 120 through the buckle structure.

[0053] The bracket assembly 200 is arranged in the inner cavity formed by the oil cup 111 and the lower shell 120. The bracket assembly 200 includes a first air inlet flow channel 201, the first end of the first air inlet flow channel 201 communicates with the first air inlet hole 121, and the second end of the first air inlet flow channel 201 is connected with the exhaust pipe 113. The axis of the exhaust pipe 113 extends in the first direction, and the center line of the first air inlet flow channel 201 also extends in the first direction. The atomizing core 300 is arranged at least on the opposite sides of the first air inlet flow channel 201 and in the bracket assembly 200. The atomizing core 300 includes a base body 310 and a heating element, the heating element is arranged on one side of the base body 310, and at least the heating element is located in the first air inlet flow channel 201. When the atomizer works, the heating element heats and atomizes the aerosol substrate to generate aerosol in the first air inlet flow channel 201, and the aerosol directly enters the exhaust pipe 113 and the suction nozzle 112 for the user to suck.

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

[0055] In the embodiment, the atomizer comprises a shell assembly 100, a support assembly 200 and an atomizing core 300. The shell assembly 100 comprises an upper shell 110 and a lower shell 120 connected together. The upper shell 110 can comprise 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. The lower shell 120 is provided with a first air inlet hole 121. The support assembly 200 is arranged in an inner cavity formed by the oil cup 111 and the lower shell 120. The support assembly 200 comprises a first air inlet flow channel 201. The first end of the first air inlet flow channel 201 is in communication with the first air inlet hole 121. The second end of the first air inlet flow channel 201 is connected to the exhaust pipe 113. The atomizing core 300 is arranged at least on opposite sides of the first air inlet flow channel 201 and located in the support assembly 200. The atomizing core 300 comprises a base body 310 and a heating element. The heating element is arranged at least in the first air inlet flow channel 201. The first air inlet flow channel 201 is directly connected to the exhaust pipe 113. The first air inlet flow channel 201 is arranged directly below the atomizing core 300. Compared with the scheme that the aerosol needs to bypass the atomizing core 300 from the side to enter the exhaust pipe 113, the loss of the aerosol in the air inlet flow channel is reduced, and the aroma and taste of the aerosol are improved.

[0056] In some embodiments, the first air inlet flow channel 201 and the exhaust pipe 113 are centrally aligned. That is, the center line of the first air inlet flow channel 201 coincides with the center line of the exhaust pipe 113.

[0057] The first air inlet flow channel 201 and the exhaust pipe 113 are centrally aligned, which can further reduce the bypass of the aerosol and reduce the loss of the aerosol in the air inlet flow channel.

[0058] Referring to Figs. 4 to 6 As shown, the support assembly 200 comprises an upper support 210 and a lower support 220 connected together. The upper support 210 comprises a main body portion 211. In the second direction, opposite sides of the main body portion 211 are provided with accommodating holes 2111. The accommodating holes 2111 are in communication with the first air inlet flow channel 201. The atomizing core 300 is arranged in the accommodating holes 2111. The second direction is perpendicular to the first direction. The main body portion 211 is provided with first liquid inlet holes 2112 away from the lower support 220. The two first liquid inlet holes 2112 are located on opposite sides of the first air inlet flow channel 201. The first liquid inlet holes 2112 are in communication with the liquid storage cavity 101 and the accommodating holes 2111.

[0059] The base body 310 is provided with an atomization surface on the side of the heating element, and a liquid suction surface on the side away from the heating element. The base body 310 can be made of porous ceramic, porous metal, porous glass or other porous materials to ensure that the aerosol substrate can permeate from the liquid suction surface to the atomization surface. When the atomizer is working, the aerosol substrate in the liquid storage cavity 101 can enter the accommodating hole 2111 through the first liquid inlet hole 2112, then permeate to the liquid suction surface of the base body 310, and then permeate to the atomization surface through the base body 310, so that the heating element can heat and atomize the aerosol substrate to generate aerosol for the user to inhale.

[0060] The aerosol substrate permeates to the liquid suction surface of the base body 310 through the first liquid inlet hole 2112 and the accommodating hole 2111, which can prevent the aerosol substrate from leaking. The atomizer core 300 is arranged symmetrically on both sides to ensure that the area of the liquid suction surface and the atomization surface of the base body 310 is large enough, thereby ensuring that the atomizer has sufficient atomization power.

[0061] In some embodiments, the support assembly 200 further includes a silica gel sleeve 230 and a side support 240, the side support 240 including an insertion portion 241 and a connecting portion 242, the insertion portion 241 being arranged in the accommodating hole 2111. It should be noted that, Figs. 4 to 6 The insertion portion 241 is provided with a second liquid inlet hole 2411 on the side close to the liquid storage cavity 101, and a third liquid inlet hole 2412 on the side close to the base body 310, and the silica gel sleeve 230 connects the base body 310 and the insertion portion 241. The silica gel sleeve 230 is provided with a communication hole corresponding to the position of the second liquid inlet hole 2411, which communicates the inside and outside of the silica gel sleeve 230.

[0062] In some embodiments, the second liquid inlet hole 2411 can penetrate the insertion portion 241 up and down, and the second liquid inlet hole 2411 away from the liquid storage cavity 101 is sealed by the silica gel sleeve 230, thereby preventing the side support 240 from being installed in reverse and affecting the working of the atomizer. The connecting portion 242 is in a U-shaped structure, i.e. the connecting portion 242 includes a connecting arm and two cantilever arms located at both ends of the connecting arm, the cantilever arms being perpendicular to the connecting arm, the insertion portion 241 being connected to the connecting arm of the connecting portion 242, and a buckle can be arranged on the cantilever arm of the connecting portion 242, and the side support 240 is connected to the outer surface of the main body portion 211 through the buckle on the cantilever arm.

[0063] When the atomizer is working, the aerosol substrate in the liquid storage cavity 101 can permeate to the liquid suction surface of the base body 310 through the first liquid inlet hole 2112, the second liquid inlet hole 2411, the third liquid inlet hole 2412 and the silica gel sleeve 230, and then permeate to the atomization surface through the base body 310, so that the heating element can heat and atomize the aerosol substrate to generate aerosol for the user to inhale.

[0064] The support assembly 200 further comprises a silica gel sleeve 230 and a side support 240 for mounting and positioning the atomizing core 300, and the silica gel sleeve 230 is used to seal the liquid inlet channel to avoid leakage of the aerosol substrate.

[0065] In some embodiments, the lower support 220 comprises a first cylinder 221, a second cylinder 222, and a support bottom plate 223, the support bottom plate 223 is arranged in the first cylinder 221, and the second cylinder 222 is arranged in the first cylinder 221 and located on the side of the support bottom plate 223 close to the upper support 210. The second cylinder 222 is connected with the support bottom plate 223, a buffer cavity 202 is formed between the first cylinder 221 and the second cylinder 222, the buffer cavity 202 is in communication with the first air inlet channel 201, and the accommodation hole 2111 is in communication with the buffer cavity 202.

[0066] When the atomizer works, the aerosol substrate in the liquid storage cavity 101 is continuously consumed, and the gas pressure in the liquid storage cavity 101 decreases. Since the buffer cavity 202 is in communication with the liquid storage cavity 101 and the first air inlet channel 201, external air can enter the liquid storage cavity 101 through the first air inlet channel 201 and the buffer cavity 202 to balance the gas pressure inside and outside the liquid storage cavity 101, so as to avoid the problem that the gas pressure in the liquid storage cavity 101 is too small to cause the aerosol substrate to be supplied in time, thereby affecting the user experience.

[0067] In some embodiments, the upper support 210 further comprises a third cylinder 212 and a fourth cylinder 213, both of which are located on the side of the main body part 211 away from the liquid storage cavity 101. The third cylinder 212 is located in the first cylinder 221, and the third cylinder 212 is connected with the first cylinder 221. The fourth cylinder 213 is located in the third cylinder 212, one end of the fourth cylinder 213 is located in the second cylinder 222, and a gap is formed between the fourth cylinder 213 and the second cylinder 222. The buffer cavity 202 is in communication with the first air inlet channel 201 through the gap between the fourth cylinder 213 and the second cylinder 222. The second cylinder 222 and the main body part 211 are matched with a small gap, for example, the gap between the second cylinder 222 and the main body part 211 is 1-5 mm.

[0068] The buffer cavity 202 is in communication with the first air inlet channel 201 through the gap between the fourth cylinder 213 and the second cylinder 222, which avoids the problem that the opening of the side wall of the second cylinder 222 causes the liquid storage capacity of the buffer cavity 202 to decrease, and further causes the aerosol substrate in the buffer cavity 202 to leak.

[0069] In some embodiments, the upper support 210 further comprises a ventilation pipe 214 located between the third cylinder 212 and the fourth cylinder 213, and the ventilation pipe 214 communicates the containing hole 2111 and the buffer cavity 202. The atomizer further comprises a backflow rod 400 arranged in the ventilation pipe 214, and the contact surface of the backflow rod 400 with the ventilation pipe 214 is provided with a backflow groove 2141, or the contact surface of the ventilation pipe 214 with the backflow rod 400 is provided with a backflow groove 2141, and the containing hole 2111 and the buffer cavity 202 are communicated through the backflow groove 2141. That is, the backflow groove 2141 can be provided on the backflow rod 400 or the inner wall of the ventilation pipe 214, and the specific arrangement can be determined according to the situation. The backflow rod 400 is made of plastic, silica gel, metal, ceramic and the like. In some embodiments, the backflow rod 400 is a porous structure cylinder made of plastic, silica gel, metal or ceramic, or a cylinder made of cotton.

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

[0071] In some embodiments, the second air inlet hole 2231 is arranged on the support bottom plate 223, the third air inlet hole 2113 is arranged on the main body 211 away from the liquid storage cavity 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 communicated to form the first air inlet channel 201. The main body 211 is provided with an air outlet hole 2114 at the end close to the liquid storage cavity 101, the air outlet hole 2114 and the third air inlet hole 2113 are communicated, and the end of the exhaust pipe 113 away from the mouthpiece 112 is inserted into the air outlet hole 2114, so that the exhaust pipe 113 is directly connected with the first air inlet channel 201.

[0072] The lower support 220 further comprises an electrode sheath 224, and the two electrode sheaths 224 are located in the second cylinder 222 and connected with the support bottom plate 223, and the two electrode sheaths 224 are located on the two sides opposite to the second air inlet hole 2231.
