By the design, the installation and positioning are more accurate and the installation is firmer, and the anti-falling function can be realized. Of course, in other embodiments, there may be one, but the positioning effect is not good when installing, and it is easy to fall off after installing; the number of the positioning devices can be five or six, the positioning effect is more accurate and the positioning devices are firm after installation, but the manufacturing cost is correspondingly increased, and the assembly efficiency is correspondingly reduced.

As shown in fig. 9, the heat generating device 150 includes a heating wire 151 and a heating wire holder 153; the heating wire 151 and the heating wire holder 153 are integrally formed, and the heating wire holder 153 has a hollow structure or a porous structure.

With such a square frame structure of the heater supporter 153, the design of the heater 151 can only adopt a planar structure, such as a planar reciprocating folding type heater 151 shown in fig. 10a, a coil type heater 151 shown in fig. 10b, a planar quadrangular diagonal type heater 151 shown in fig. 10c, and so on.

As shown in fig. 4-7, an air inlet 160 is opened on a side wall of the electronic atomizer 200, and the air inlet 160 is communicated with the atomizing chamber 121 of the electronic atomizer 200 through an air inlet channel 161; the horizontal axis of the air inlet channel 161 is perpendicular to the longitudinal axis of the atomizing channel 124 of the electronic atomizer 200; the connection between the air inlet channel 161 and the atomizing chamber 121 is bent toward the atomizing chamber 121 to form an arc angle, and then the aperture is reduced.

Specifically, an air inlet 160 is formed on a side wall of the lower end of the housing 120 of the electronic atomizer 200, an air inlet channel 161 is formed inside the lower end of the housing 120, one end of the air inlet channel 161 is in air flow connection with the air inlet 160, and the other end is in air flow connection with the atomizing chamber 121; the size, the arrangement position and the like of the air inlet hole 160 are matched with the air hole 201 arranged on the power supply 200, and the air inlet hole 160 and the air hole 201 form air flow communication.

The connection part 162 of the air inlet channel 161 and the atomizing cavity 121 is bent towards the atomizing cavity 121, and the connection part 162 is bent to form an arc angle, and then the aperture is reduced, wherein the arc angle is 90-120 degrees, and preferably 100 degrees; and the aperture of the connection part 162 of the air inlet channel 161 and the atomizing chamber 121 is reduced to be about 0.6-0.9 times, preferably 0.8 times, the space of the air inlet hole 160.

The tail part of the air inlet channel 161 is bent into an air inlet channel which is approximately 90 degrees and is arc-shaped and contracted, so that a flow-resisting and speed-reducing effect can be performed when external atmosphere enters the atomizing cavity, and atomized liquid or smoke oil is prevented from being sucked out due to the fact that the air flow speed in the air inlet channel is too high; meanwhile, the condensed fluid at the air inlet can be eliminated or reduced, and the condensed fluid heating devices are prevented from being inhaled into the mouth of a user after being evaporated and condensed along with atomized steam. In a word, this kind of electronic atomizer can promote user's smoking taste greatly and experience.

Preferably, the number of the air inlets 160 is at least two, which can balance each other and buffer the air flow velocity after the outside air is sucked into the air inlet channel 161, so as to reduce or eliminate the air flow to take away part of the tobacco tar, and the smoke is sucked into the cavity of the user along with the atomized steam, thereby reducing the mouth experience.

The air flow path at this time is: the outside air-air hole 201-the air inlet hole 160-the air inlet channel 161-the atomizing cavity 121-the atomizing channel 124-the air suction channel 111-the mouth, that is: ambient air-a airflow path-b airflow path-mouth.

Preferably, in the electronic atomizer 100, the atomizing chamber 121, the atomizing passage 124 and the suction passage 111 in the suction nozzle are arranged in an axial direction.
