The atomizer 1 is used for accommodating liquid matrix, heating and atomizing the liquid matrix and conveying mist, and the host 4 is used for supplying power to the atomizer 1 and controlling the whole electronic atomization device to be opened or closed. It is to be understood that the electronic atomization device is not limited to be cylindrical, and may be other shapes such as elliptic cylinder, square, etc.
As shown in fig. 3-4, the main body 4 may include a cylindrical housing 41 with a receiving cavity 410, a conductive connector 42 disposed on the top of the housing 41, a cylindrical first electrode column 43 insulatedly disposed in the connector 42, and a battery device 45 and an air switch 46 disposed in the receiving cavity 410.
The connector 42 is used for connecting to the atomizer 1 and may be made of metal, such as stainless steel, preferably 316 stainless steel containing no heavy metals. The connection head 42 may include a cylindrical body 421 and a flange 422 integrally combined with the body 421 along a longitudinal direction in some embodiments. The outer diameter of the body 421 is adapted to the inner diameter of the housing 41 to be tightly inserted into the housing 41, and the two are usually fixed to each other by riveting. The inner wall surface of the body portion 421 is formed with an internal thread for screwing with the atomizer 1. The outer diameter of the flange portion 422 is larger than the outer diameter of the body portion 421 and is comparable to the outer diameter of the housing 41, and the flange portion 422 is pressed against the upper side of the housing 41 to realize positioning during assembly.
The flange portion 422 is formed with at least one air intake hole 4221 to allow external air to enter the receiving chamber 410. The at least one air inlet hole 4221 is opened on the flange portion 422 and can be formed by inward sinking of the outer edge of the flange portion 422, so that special opening on the housing 41 can be avoided, the processing technology is saved, and meanwhile, the attractiveness and the integrity of the appearance of the product can be ensured. At least one air guide groove 4211 is formed on an outer wall surface of the body portion 421, and the at least one air guide groove 4211 is disposed corresponding to the at least one air inlet hole 4221. The at least one air guide groove 4211 extends downward from the upper end surface of the body portion 421, thereby communicating the air intake hole 4221 with the receiving chamber 410. The air inlet hole 4221, the air guiding groove 4211, the accommodating cavity 410 and the central through hole of the first electrode column 43 together form a first sensing air passage.
The first electrode column 43 is insulatively disposed in the body portion 421. The outer circumference of the first electrode shaft 43 and the inner circumference of the body portion 421 may be insulated by providing an insulating sheath 44. The connector 42 and the first electrode column 43 are electrically connected to the negative electrode and the positive electrode (or the positive electrode and the negative electrode) of the battery device 45, respectively.

The base assembly 10 may in some embodiments comprise an electrically conductive base 11, a second electrode column 12 arranged longitudinally insulated in the base 11, and an induction conduit 13 arranged longitudinally through the upper end of the second electrode column 12. The base 11 is used for connecting and contacting with the connector 42 of the host 4, and the base 11 may be made of metal, such as stainless steel, preferably 316 stainless steel containing no heavy metal.

The central through hole of the second electrode column 12 is communicated with the central through hole of the induction pipeline 13 to form a second induction air passage. The second sensing air passage and the first sensing air passage together form an air switch sensing air passage of the electronic atomization device for controlling the operation of the air switch 46. Specifically, when the air is sucked from the outside, the air flow passes through the air inlet hole 4221, the air guide groove 4211, the accommodating cavity 410, the first electrode column 43 and enters the second electrode column 12 and the sensing pipeline 13 in sequence, negative pressure is formed in the accommodating cavity 410, and the air switch 46 is activated under the negative pressure.

The body portion 2511 may have a substantially rectangular or other longitudinal shape, and the two catch arms 2512 are disposed on two opposite sides of the upper end of the body portion 2511 in the longitudinal direction. The extension 2513 may be cylindrical, and the extension 2513 may increase the axial length of the through hole 2510 and increase the installation space of the heating element.
A liquid storage cavity 210 for storing liquid matrix is defined between the inner wall surface of the shell 21 and the outer wall surface of the outer tube 22, and at least one liquid inlet 2210 is arranged on the outer tube 22 so that the liquid matrix in the liquid storage cavity 210 can enter the outer tube 22 through the at least one liquid inlet 2210 to conduct and connect the liquid absorption 251 with the liquid storage cavity 210. The inner wall surface of the outer tube 22 and the outer wall surface of the inner tube 27 define an air inlet duct 220, and the air inlet duct 220 is communicated with the air inlet of the atomizing chamber to allow the external air to enter the atomizing chamber.

A neck 211 is formed by extending the inner ring of the lower end of the housing 21 radially inward, the inner diameter of the neck 211 is equivalent to the inner diameter of the seat 111 of the base 11, and the housing 21 is pressed against the top of the seat 111 by the neck 211. A sealing ring 15 may be provided between the bottom of the neck 211 and the top of the housing 111 to prevent leakage.
The outer tube 22 may include a first tube section 221 at a lower portion, a second tube section 222 at a middle portion, and a third tube section 223 at an upper portion in some embodiments, and the inner and outer diameters of the first, second, and third tube sections 221, 222, 223 are all decreased such that the outer tube 22 has a stepped shaft shape. The outer diameter of the inner tube 27 is smaller than the inner diameter of the third tube section 223 so that an annular inlet duct 220 is defined between the inner wall surface of the third tube section 223 and the outer wall surface of the inner tube 27.
