[0093] The mounting base 1 includes a shell 113 and a partition 114 disposed in the shell 113 . The partition 114 has a lower liquid hole 111 . The lower liquid hole 111 is communicated with the liquid storage bin 4 , that is, the lower liquid hole 111 is connected to the liquid storage bin 4 .

[0094] In this embodiment, the partition 114 divides the space in the housing 113 into a lower liquid chamber 116 and an access chamber 115, the lower liquid chamber 116 and the access chamber 115 are connected through the partition 114, and an air outlet channel 131 is also provided on the housing 113 on the same side as the lower liquid chamber 116. The mounting base 1 is embedded in the atomizer housing 209, and the ventilation pipe is connected to the air outlet channel 131, and the smoke in the atomization chamber 125 is guided to the user's mouth through the air flow channel 13 and the ventilation pipe.

[0095] In other embodiments, the mounting base 1 may not be embedded in the atomizer housing 209, but only requires the lower liquid hole 111 to be connected to the liquid storage tank 4. For example, the liquid storage tank 4 is a flexible liquid storage tank, a liquid storage ball, etc., which is connected to the partition 114 and the liquid storage tank 4 is connected to the lower liquid hole 111.

[0096] The partition 114 can be a plate body with a lower liquid hole 111 in the middle, or the partition 114 can be a plate with multiple lower liquid holes 111 in the middle. It only needs to be connected to the liquid storage tank 4 through the lower liquid hole 111 on the partition 114, and this application does not impose any restrictions on this.

[0097] The atomizer core 2 is assembled in the access cavity 115 and blocks the lower liquid cavity 116 , and the atomizer core 2 is communicated with the lower liquid cavity 116 . The lower liquid cavity 116 and the lower liquid hole 111 guide the smoke oil to the atomizer core 2 , so that the atomizer core 2 atomizes the smoke oil to form smoke.

[0098] The sealing member 3 is arranged on the side of the partition 114 away from the liquid storage bin 4 and between the partition 114 and the atomizer core 2. The atomizer core 2 presses against the sealing member 3 to prevent the leakage of the smoke oil. The sealing member 3 has an opening 31 connected to the lower liquid hole 111, so that the opening 31 is connected to the liquid storage bin 4, and the smoke oil enters the atomizer core 2 through the opening 31.

[0099] The lower seat body 12 is connected to and covers one end of the upper seat body 11 away from the liquid storage tank 4, and the lower seat body 12 abuts against the atomizer core 2, so that the atomizer core 2 abuts against the sealing member 3, and the space formed by the upper seat body 11, the atomizer core 2 and the lower seat body 12 constitutes an atomizer cavity 125, the atomizer core 2 atomizes the e-liquid and forms smoke in the atomizer cavity 125, and the atomizer cavity 125 is communicated with the air flow channel 13.

[0100] In another optional embodiment, an air guide groove structure 151 is provided between the mounting seat 1 and the sealing member 3, and the air guide groove structure 151 connects the liquid storage bin 4 and the external atmosphere. After the liquid storage space is filled with tobacco oil, the tobacco oil seals the air guide groove structure 151.

[0101] The air guide groove structure 151 can connect the atomizing chamber 125 and the liquid storage tank 4 , and further connect the liquid storage tank 4 and the external atmosphere through the atomizing chamber 125 .

[0102] The present application provides an air guide groove structure 151 between the mounting seat 1 and the sealing member 3, and the air guide groove structure 151 connects the liquid storage tank 4 and the atomization chamber 125, so that the air pressure and hydraulic pressure in the liquid storage tank 4 and the capillary tension, resistance and atmospheric pressure of the air guide groove structure 151 on the smoke oil can reach a dynamic balance by adjusting the smoke oil stored in the air guide groove structure 151, thereby avoiding the occurrence of poor liquid discharge and leakage of the atomizer 10, and improving the quality of the atomizer 10.

[0103] Specifically, when the air pressure in the liquid storage bin 4 decreases to reach the negative pressure threshold, the air in the atomizing chamber 125 can enter the liquid storage bin 4 through the air guide groove structure 151 to achieve ventilation, so that the air pressure in the liquid storage bin 4 increases, thereby avoiding the situation where the liquid is not flowing smoothly due to the low air pressure in the cavity, and improving the quality of the atomizer 10. When the air pressure in the liquid storage bin 4 increases due to being heated, more smoke oil will enter the air guide groove structure 151, and then the air pressure in the liquid storage bin 4 can be appropriately reduced to avoid leakage, which also improves the quality of the atomizer 10.

[0104] In other embodiments, the seal 3 is provided with an air guide groove structure 151. Specifically, the seal 3 is provided with an air guide groove structure 151 on one side facing the partition 114 and / or on one side facing the atomizer core 2, or the air guide groove structure 151 can also be provided inside the seal 3.

[0107] Since the air guide groove structures 151 are all located on the side of the partition plate 114 away from the liquid storage tank 4, the smoke oil in the air guide groove structures 151 has relatively the same hydraulic pressure value.

[0108] The air guide groove structure 151 can be arranged in a circuitous manner on the partition 114, which can increase the flow resistance of the smoke oil leakage of the air exchange groove structure 151 and extend the path of the smoke oil leakage. The air guide groove structure 151 can also be arranged in a straight line, as long as the air guide groove structure 151 can connect the lower liquid hole 111 and the atmosphere, and this application does not limit this.

[0109] The air guide groove structure 151 can also be provided in multiple pieces, and the multiple air guide groove structures 151 can simultaneously perform ventilation to increase the air pressure in the liquid storage bin 4, and the multiple air guide groove structures 151 can also simultaneously take in liquid to reduce the air pressure in the liquid storage bin 4, so that the multiple air guide groove structures 151 can increase the convenience of adjusting the air pressure in the liquid storage bin 4, so that the air pressure in the liquid storage bin 4 can be quickly adjusted.

The cross-sectional area of ​​the cache groove 153 along the path direction of the air guide groove structure 151 is larger than the cross-sectional area of ​​the air guide groove structure 151 in the same direction. The seal 3 covers the air guide groove structure 151 and the cache groove 153 to prevent liquid leakage from the air guide groove structure 151 and the cache groove 153.

[0111] The buffer groove 153 is used to buffer the e-liquid, and the cross-sectional area of ​​the buffer groove 153 along the path direction of the air guide groove structure 151 is larger than the cross-sectional area of ​​the air guide groove structure 151 in the same direction, thereby improving the liquid storage capacity of the air guide groove structure 151 to prevent the e-liquid from leaking from the air guide groove structure 151.

[0112] After research, it was found that the depth of the air guide groove structure 151 should be set to 0.1mm to 0.5mm, the width of the air guide groove structure 151 in a direction perpendicular to its path direction should be set to 0.1mm to 0.5mm, and the width of the cache groove 153 is greater than the width of the air guide groove structure 151, and the depth of the cache groove 153 is greater than or equal to the depth of the air guide groove structure 151.

[0113] Specifically, the air inlet 126 of one of the air guide groove structures 151 is adjacent to the ventilation port of the other air guide groove structure 151, and the ventilation port of the air guide groove structure 151 is adjacent to the air inlet 126 of the other air guide groove structure 151, and the two air guide groove structures 151 are arranged around the liquid lowering hole 111, the ventilation port is connected to the liquid storage tank 4, and the air inlet 126 is connected to the atmosphere, so that the air guide groove structure 151 has a longer length and can store more smoke oil. It is also possible to conveniently adjust the air pressure in the liquid storage tank 4, and the ventilation ports of the two air guide groove structures 151 are arranged in different positions, which can avoid the aggregation of bubbles generated by the ventilation ports at the same location and increase the difficulty of lowering the smoke oil.

[0114] The length and cross-sectional area of ​​the air guide groove structure 151 and the length and cross-sectional area of ​​the buffer groove 153 can be set according to the specifications of the atomizer 10 to facilitate adjusting the air pressure in the liquid storage tank 4.

The gas in the atomization chamber 125 is squeezed into the first air guide groove 1511 and the second air guide groove 1512 due to the pressure difference, and the gas in the first air guide groove 1511 enters the liquid storage tank 4 through the first air guide hole 1521. When the amount of gas transmitted by the first gas guide groove 1511 is greater than the amount of gas transmitted by the first gas guide hole 1521, the third gas guide groove 1513 transmits the gas not transmitted in the first gas guide groove 1511 to the liquid storage tank 4 through the lower liquid hole 111; when the amount of gas transmitted by the second gas guide groove 1512 is greater than the amount of gas transmitted by the second gas guide hole 1522, the fourth gas guide groove 1514 transmits the gas not transmitted in the second gas guide groove 1512 to the liquid storage tank 4 through the lower liquid hole 111; gas is transmitted to the liquid storage tank 4 through the first gas guide hole 1521, the second gas guide hole 1522 and the lower liquid hole 111, so that the air pressure in the liquid storage tank 4 and the atomization chamber 125 is balanced, and then the smoke oil in the liquid storage tank 4 enters the atomization core 2 through the lower liquid hole 111, so that the smoke oil in the liquid storage tank 4 can be smoothly transmitted to the atomization core 2 through the lower liquid hole 111, thereby avoiding dry burning of the atomization core 2.

[0140] The atomizer 10 further includes a sealing member 3, which is disposed between the mounting seat 1 and the atomizing core 2. The sealing member 3 may be a sealing ring. The porous substrate 21 may be any one of porous ceramics and porous metals.

[0141] The porous matrix 21 is in communication with the liquid stored in the liquid storage tank 4, and absorbs the liquid from the liquid storage tank 4 through capillary force; the heating element 22 is used to heat the liquid of the atomized porous matrix 21. In one embodiment, the porous matrix 21 includes an oil transfer portion 211 and a protrusion 212 integrally formed on one side of the oil transfer portion 211, and the leakage buffer structure 122 is in contact with the peripheral edge of the surface of the side of the oil transfer portion 211 provided with the protrusion 212. The surface of the protrusion 212 away from the oil transfer portion 211 is the atomization surface 214, and the surface of the oil transfer portion 211 in contact with the smoke oil is the liquid absorption surface 213. The leakage buffer structure 122 is in contact with the edge of the surface of the side of the oil transfer portion 211 provided with the protrusion 212, that is, the leakage buffer structure 122 is in contact with the edge of the oil transfer portion 211 and is spaced from the protrusion 212, so that the high temperature of the heating element 22 on the atomization surface 214 can avoid damaging the leakage buffer structure 122. The atomization surface 214 is provided with a heating element 22. Specifically, the heating element 22 can be a heating film or a heating circuit. In a specific embodiment, the heating element 22 is electrically connected to the electrode, and one end of the electrode passes through the base 121 and is connected to the power supply assembly 202. Specifically, the oil transfer part 211 and the protrusion 212 are integrally formed, and the oil transfer part 211 and the protrusion 212 are both porous materials. For example, the material of the oil transfer part 211 and the protrusion 212 can be porous ceramics or porous metals, but are not limited to these two materials, as long as the smoke oil in the liquid storage tank 4 can be transferred to the heating element 22 for atomization through capillary action. Among them, the oil transfer part 211 only covers part of the leakage buffer structure 122. Among them, the capillary force of the porous matrix 21 is greater than the capillary force of the leakage buffer structure 122. When the heating element 22 heats the liquid of the atomized porous matrix 21, the liquid received by the leakage buffer structure 122 can flow back to the porous matrix 21 and be heated and atomized.

[0142] The mounting seat 1 has an atomizing chamber 125, and the atomizing core 2 is accommodated in the atomizing chamber 125. The liquid leakage buffer structure 122 is connected to the bottom of the atomizing chamber 125 and absorbs the accumulated liquid at the bottom of the atomizing chamber 125 through capillary force. The mounting seat 1 includes an upper seat body 11 and a lower seat body 12. The lower seat body 12 includes a base 121. The upper seat body 11 is provided with a lower liquid hole 111. The liquid in the liquid storage tank 4 flows to the porous matrix 21 through the lower liquid hole 111. The liquid leakage buffer structure 122 is arranged on the lower seat body 12. The porous matrix 21 includes a liquid absorption surface 213 and an atomizing surface 214. The liquid absorption surface 213 is connected to the lower liquid hole 111. The heating element 22 is arranged on the atomizing surface 214. The porous matrix 21 is in contact with the liquid leakage buffer structure 122.

[0143] Among them, when the pressure of the liquid storage tank 4 increases, the pressure of the liquid storage tank 4 is greater than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 squeezes the liquid in the liquid storage tank 4 to the porous matrix 21, causing excess liquid to overflow from the porous matrix 21, and the leakage buffer structure 122 receives and locks the overflowing excess liquid; when the pressure of the liquid storage tank 4 decreases, the pressure of the liquid storage tank 4 is less than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 causes the liquid in the leakage buffer structure 122 to flow back to the porous matrix 21 in contact with it through capillary action, and the porous matrix 21 returns the liquid therein to the liquid storage tank 4.

[0144] In this embodiment, the upper body 11 and the lower body 12 are made of one piece, and a slot 112 can also be set on the upper body 11. A clamping member 124 is provided on the outer wall of the lower body 12 for clamping with the slot 112 on the upper body 11 to fix the lower body 12 to the upper body 11.

[0145] The material of the liquid leakage buffer structure 122 is a porous material, and the porous material can be a hard porous material or a soft porous material.

[0146] When the material of the leakage buffer structure 122 is a hard porous material, in order to save space, the leakage buffer structure 122 can also be used to support the atomizer core 2. The hard porous material is at least one of porous ceramics and porous metals, and can also be other materials with supporting and liquid absorbing capabilities.

It can be understood that if the atomizer core 2 is fixed by other components, the sub-leakage buffer 1221 may not be used to support the atomizer core 2. When the pressure of the liquid storage tank 4 is greater than the pressure of the atomization chamber 125, the sub-leakage buffer 1221 can collect the smoke oil leaked from the porous matrix 21; when the pressure of the liquid storage tank 4 is less than the pressure of the atomization chamber 125, the smoke oil stored in the sub-leakage buffer 1221 can be refluxed to the porous matrix 21 in contact with it, thereby achieving effective utilization of the leaked oil, so that the leakage buffer structure 122 can realize multiple cycles of collecting and reflux of smoke oil. The liquid absorption capacity of the porous material used to make the liquid leakage buffer structure 122 is smaller than that of the porous material used to make the oil transfer part 211. The condensate collection structure 14 and the ventilation channel 15 are connected to the sub-leakage buffer structure 122, and the liquid collected in the condensate collection structure 14 flows back to the porous matrix 21 in contact with it through the sub-leakage buffer structure 122.

Specifically, the leakage buffer structure 122 includes a sub-leakage buffer 1221 and a connecting portion 1222 connecting the sub-leakage buffer 1221 away from the end of the porous substrate 21. The material of the sub-leakage buffer 1221 and the connecting portion 1222 is a porous material, for example, it can be a material with supporting and liquid absorption capabilities such as porous ceramics and porous metals. The connecting portion 1222 is provided with a channel matching the air inlet 126 provided on the base 121. The connecting portion 1222 is used to absorb the condensed smoke oil after the atomized smoke oil is condensed in the atomization chamber 125 formed by the leakage buffer structure 122 and the atomization core 2, so as to prevent the condensed smoke oil from leaking through the air inlet 126. The condensate collecting structure 14 and the ventilation channel 15 are in communication with the sub-leakage buffer 1221 and / or the connecting piece, and the liquid collected in the condensate collecting structure 14 flows back to the porous matrix 21 in contact therewith through the leakage buffer structure 122.

The first sub-body 1231 and the second sub-body 1232 can be arranged parallel and vertically on the base 121. In another optional embodiment, the first sub-body 1231 and the second sub-body 1232 can be tilted and symmetrically arranged on the base 121, and the distance between the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 is greater than the distance between the ends of the first sub-body 1231 and the second sub-body 1232 connected to the base 121. Among them, the material of the first sub-body 1231 and the second sub-body 1232 is dense ceramic, dense metal or glass material, and can also be other materials with support capacity and no liquid absorption capacity. In another specific embodiment, the leakage buffer structure 122 is arranged at the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121, and the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 are connected to the oil transfer part 211 through the leakage buffer structure 122. The leakage buffer structure 122 can be a porous material with supporting and liquid absorbing capabilities. For example, the material of the leakage buffer structure 122 can be a porous ceramic, porous metal or other material with supporting and liquid absorbing capabilities. The leakage buffer structure 122 can collect the smoke oil leaked from the oil transfer part 211 in the leakage buffer structure 122, and can also make the smoke oil stored in the leakage buffer structure 122 flow back to the oil transfer part 211 in contact with the leakage buffer structure 122, thereby realizing the effective use of the stored smoke oil and realizing multiple cycles of collecting and reflowing the smoke oil. The material of the leakage buffer structure 122 can also be a material with liquid absorbing capabilities and no supporting capabilities, such as cotton, fiber, and liquid absorbing resin. The liquid absorption capacity of the porous material used to make the liquid leakage buffer structure 122 is smaller than that of the porous material used to make the oil transfer part 211. The condensate collection structure 14 and the ventilation channel 15 are connected to the liquid leakage buffer structure 122, and the liquid collected in the condensate collection structure 14 flows back to the porous matrix 21 in contact with it through the liquid leakage buffer structure 122.

The guide channel 1233 can be a groove structure, and the groove size of the guide channel 1233 is larger than the size of the first capillary groove 1223. The opening 31 at one end of the flow guiding channel 1233 is arranged on the inner side wall of the first sub-support 1271 and the second sub-support 1272, and the opening 31 at the other end is located on the end surface of the first sub-support 1271 and the second sub-support 1272 away from the base 121, and the leakage buffer structure 122 filled in the flow guiding channel 1233 is in contact with the oil transfer part 211. The cross-sectional size of the groove arranged on the surface of the first sub-support 1271 and the second sub-support 1272 away from the base 121 is not less than the contact size of the oil transfer part 211 and the first sub-support 1271 and the second sub-support 1272. Specifically, the width of the opening 31 of the guide channel 1233 at the end surface of the first sub-support 1271 and the second sub-support 1272 in the direction of the line connecting the first sub-support 1271 and the second sub-support 1272 is not less than the contact width between the first sub-support 1271 and the second sub-support 1272 and the oil transfer part 211 in the direction of the line connecting the first sub-support 1271 and the second sub-support 1272.

One end of the leakage buffer structure 122 is connected to the oil transfer part 211, and the other end extends to between the first sub-support 1271 and the second sub-support 1272, and can also extend to the surface of the base 121, so as to collect the condensed liquid of the atomized smoke oil, and prevent the atomized smoke oil from leaking from the air inlet 126 arranged on the base 121 after cooling and liquefaction, thereby affecting the user's experience. When the pressure in the liquid storage tank 4 decreases, the leakage buffer structure 122 can also return the collected smoke liquid to the oil transfer part 211 in contact with it through capillary action, thereby realizing effective utilization of the leakage liquid, so that the leakage buffer structure 122 can collect and return the smoke liquid in multiple cycles. Among them, the liquid absorption capacity of the leakage buffer structure 122 is less than the liquid absorption capacity of the oil transfer part 211. Specifically, the liquid absorption capacity of the porous material used to make the leakage buffer structure 122 is less than the liquid absorption capacity of the porous material used to make the oil transfer part 211.

At the same time, the volume of the bubbles in the liquid storage tank 4 will shrink, reducing the pressure of the liquid storage tank 4. Furthermore, due to the pressure difference between the inside and outside of the liquid storage tank 4, the liquid collected and stored in the leakage buffer structure 122 will flow through capillary action along the leakage buffer structure 122 in the direction close to the oil transfer part 211 to the oil transfer part 211 connected to the leakage buffer structure 122, thereby achieving effective utilization of the collected liquid.

[0157] See 28, Fig.28 It is a schematic diagram of the phenomenon of the atomizer provided by the present invention during the heating process. As the temperature rises, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will expand, so that the pressure of the liquid storage tank 4 increases, and then the smoke oil in the atomizer core 2 leaks out from the end of the oil transfer part 211 in the atomizer core 2. The smoke oil leaked from the end of the oil transfer part 211 can flow to the first capillary groove 1223 connected to the oil transfer part 211, and the leaked smoke oil is collected by the first capillary groove 1223.

As the temperature decreases, the atomized smoke oil in the atomization chamber 125 composed of the first sub-body 1231, the second sub-body 1232, the base 121 and the atomization core 2 will cool to form smoke oil, flow to the base 121, and collect the smoke oil through the second capillary groove 1224. At the same time, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will shrink, so that the pressure of the liquid storage tank 4 is reduced. Then, due to the pressure difference between the inside and outside of the liquid storage tank 4, the smoke oil collected and stored in the first capillary groove 1223 and the second capillary groove 1224 flows to the oil transfer part 211 connected to the first capillary groove 1223 through capillary action along the direction away from the second capillary groove 1224.

When the temperature drops, the atomized smoke oil in the atomizer chamber 125 will cool to form smoke oil, flow to the base 121, and collect the smoke oil through the second capillary groove 1224. At the same time, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will shrink, reducing the pressure in the liquid storage tank 4.
