The air guide passage may have various structures:.

In the above solution, air enters the first air pass hole from the first air inflow passage, then flows through the first air guide groove, the gap between the first seal cover and the second seal cover, and the second air guide groove, and finally flows out from the hollow cavity of the base body.

In the above solution, the cover located at the bottom of the hollow cavity of the base body has certain elasticity, thus it has certain deformation space when abutting against the atomizing cotton to improve the contact effect between the atomizing cotton and the atomizing sheet, and at the same time, the second air pass hole has the effect to guide the air.

Preferably, the cover is spherical or inversely conical.

In another preferred solution, the air inlet is provided at the upper part of the shell, an accommodating cavity is formed in the middle of the tobacco tar cavity, the air outflow pipe is arranged in the accommodating cavity, a gap A is reserved between the outer wall of the air outflow pipe and the inner wall of the accommodating cavity, and the gap A communicates with the air inlet to form the first air inflow passage;.

In the above solution, the air passage is provided, therefore, after air enters the first air inflow passage, the air is guided to flow through the second gap and the third gap, thereby ensuring that the air can flow along the inner wall of the hollow cavity of the atomizing cotton, thus the smoke generated at the corner of the atomizing cotton can be carried away to avoid the accumulation of smoke and increase the concentration of the smoke. With the air pass groove, air can be guided to flow, and all the air can pass over, at a low level, the surface where the atomizing cotton is in contact with the atomizing sheet, so that the atomization is more sufficient, the atomizing efficiency is higher, and more smoke is produced.

Further, the bottom of the tobacco tar cavity is sealed by a second seal seat, a groove is formed in the middle of the second seal seat, and a second tobacco tar isolation seat is mounted in the groove;.

In order to ensure closer contact between the atomizing cotton and the atomizing sheet, the lower part of the second vertical portion is sleeved with a spring, the spring is wrapped by the atomizing cotton, the lower end of the spring abuts against the inner surface of the bottom of the atomizing cotton, the lower part of the air outflow pipe penetrates through the second tobacco tar isolation seat and is inserted into a central hole of the spring, and the flexible tube communicates with the first air outlet.

the length of the second glass fiber tube is shorter than that of the first glass fiber tube, and the air pass groove is formed at the lower part edge of the first glass fiber tube.

The second glass fiber tube mainly improves the strength of the first glass fiber tube to prevent bending during assembly.

Further, a filter screen is arranged at the lower part of the inner cavity of the air outflow pipe. The filter screen is used for blocking tobacco tar from splashing or large particle smoke from being sucked into the user's mouth when the atomizing sheet is operated.

In another preferred solution, the air inlet is provided at the upper part of the shell, a tobacco tar isolation cavity is formed in the middle of the tobacco tar cavity, an accommodating cavity is formed in the tobacco tar isolation cavity, the air outflow pipe is arranged in the accommodating cavity, a gap B is reserved between the outer wall of the air outflow pipe and the inner wall of the accommodating cavity, and the gap B communicates with the air inlet to form the first air inflow passage;
the air guide structure comprises a liner tube which is sleeved in the inner cavity of the air outflow pipe and has the performance of thermal insulation and tobacco tar absorption, a gap C is reserved between the lower end of the air outflow pipe and the bottom of the hollow cavity of the atomizing cotton, the lower end of the liner tube stretches out of the lower end of the air outflow pipe and abuts against the bottom of the hollow cavity of the atomizing cotton, the lower part edge of the liner tube is provided with an air pass hole F which communicates with the first air inflow passage, and the air pass hole F is the air guide passage.

The liner tube itself has the thermal insulation function, and the lower end of the air pipe is not in contact with the atomizing cotton, so that the heat produced by the atomizing sheet can be prevented from being transferred to the shell through the air pipe.

In addition, the liner tube has the performance of tobacco tar absorption. When the smoke flows to the upper part of the air pipe and is condensed, the condensed smoke can adsorb the condensed tobacco tar, and is guided again to the atomizing cotton from top to bottom for secondary atomizing to prevent the condensed tobacco tar from being sucked into the mouth to affect the mouthfeel.

Further, the height of the air pass hole F is <NUM> to <NUM>. The reserved air pass hole is small, thus air can be guided to flow, and all the air can pass over, at a low level, the surface where the atomizing cotton is in contact with the atomizing sheet, so that the atomization is more sufficient.

Specifically, the accommodating cavity is composed of an outer sleeve and an inner sleeve sleeved in the inner cavity of the outer sleeve, the outer sleeve comprises a hollow third seal seat arranged at the bottom of the tobacco tar cavity to seal the tobacco tar cavity and a vertical pipe fixed on the third seal seat, the inner sleeve is sleeved in the inner cavity of the vertical pipe, and the inner cavity of the inner sleeve is the accommodating cavity;.

Further, the air outflow pipe is flush with the upper end of the liner tube, and a filter screen is arranged at the upper part of the liner tube. The filter screen is used for blocking tobacco tar from splashing or large particle smoke from being sucked into the user's mouth when the atomizing sheet is operated.

Further, the liner tube is a glass fiber tube, and the air pass hole F is zigzag groove or wave groove formed around the lower part edge of the liner tube.

For better thermal insulation, the height of the gap C between the air outflow pipe and the bottom of the hollow cavity of the atomizing cotton is more than <NUM>. The lower end of the air outflow pipe is not in contact with the atomizing cotton, which can prevent the heat produced by the atomizing sheet from being transferred to the shell through the air outflow pipe.

In an improved solution, the upper end of the liner tube extends out of the upper end of the air outflow pipe and extends into the inner cavity of the suction nozzle assembly, and a gap D is reserved between the outer wall of the liner tube and the inner cavity wall of the suction nozzle assembly;
the suction nozzle assembly is detachably connected to the top of the shell.

The liner tube is directly extended up to a suction nozzle, and the suction nozzle is made of other non-metallic material such as plastic or wood, so that the entire air outflow passage can greatly reduce the occurrence of condensation. The gap D is provided to facilitate the disassembly and assembly of the suction nozzle.

Further, a thermal insulation sheet is arranged between the lower surface of the atomizing sheet and the connection electrode. The thermal insulation sheet can prevent the heat of the atomizing sheet from being transferred from the lower part to the connection electrode and the shell.

Preferably, the atomizing sheet is a solid piezoelectric ceramic sheet.

Correspondingly, the present invention also provides an electronic cigarette, comprising an external power source, and the atomizer according to the above solution, wherein the external power source is connected to the connection electrode of the atomizer.

By adding the air guide passage on the basis of the prior art, the incoming air can be correctly guided to flow, so that all the air can pass over, at a low level, the surface where the atomizing cotton is in contact with the atomizing sheet, the atomization is more sufficient, the atomizing efficiency is higher, and more smoke is produced. Moreover, cold air is prevented from flowing away directly from the air pipe to be mixed with the smoke to reduce the temperature of the smoke, thereby avoiding the phenomenon that the low temperature of the smoke affects the mouthfeel.
