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.

As shown in fig. 5-9, the atomizer 1 may in some embodiments include a base assembly 10 for detachable connection with the host computer 4, an atomizer body 20 longitudinally mounted to an upper end of the base assembly 10, and a nozzle assembly 30 longitudinally mounted to an upper end of the atomizer body 20. The base assembly 10, atomizer body 20, and nozzle assembly 30 may be coaxially assembled together.

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 outer diameter of the combining part 112 may be smaller than that of the seat 111, and the outer wall surface thereof may be formed with an external thread for being screwed with the body 421 of the connector 42. The seat 111 is pressed against the upper side of the flange 422, and the outer diameter thereof can be equivalent to the outer diameter of the flange 422 and the outer diameter of the housing 41.

The second electrode pillar 12 is used to electrically contact the first electrode pillar 43, and the central through holes of the two are communicated. The second electrode shaft 12 is arranged insulated in the longitudinal direction in the joint 112, typically by an insulating sleeve 14 arranged between the outer circumference of the second electrode shaft 12 and the inner circumference of the joint 112.

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 induction conduit 13 may be a vertical elongated tube in some embodiments, and may have an outer diameter of 0.3cm to 1.1 cm. Since the induction pipe 13 is thin and long, a small amount of condensate adheres to the induction pipe 13 due to surface tension and does not easily enter the main unit 4. The induction conduit 13 may be a metal material, such as stainless steel, preferably 316 stainless steel for medical use without heavy metals.

The atomizer body 20 may in some embodiments include a housing 21 mounted longitudinally on top of the base 11, an outer tube 22 disposed longitudinally in the housing 21, an atomizing assembly 25 disposed in the outer tube 22, and an inner tube 27 disposed longitudinally in the outer tube 22 and above the atomizing assembly 25. Both the outer tube 22 and the inner tube 27 may be made of metal, such as stainless steel, preferably 316 stainless steel containing no heavy metals.

The atomizing assembly 25 may include a liquid 251, a heating element disposed on the liquid 251, and two electrode leads 253 connected to the heating element, wherein the two electrode leads 253 are electrically connected to the base 11 and the second electrode column 12, respectively.

A heating element may be provided on the wall of the through hole 2510 for heating and atomizing the liquid substrate adsorbed in the liquid absorbing body 251 after energization. The through-hole 2510 forms an atomizing chamber for mixing mist and air generated by the atomizing assembly 25. 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. The inner wall surface of the inner tube 27 defines an air outlet duct 270, and the air outlet duct 270 is communicated with the air outlet of the atomizing chamber to guide the mixture of mist and air out of the atomizing chamber.

The housing 21 may be cylindrical in some embodiments, and may have an outer diameter comparable to the outer diameter of the housing 41. 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.

A main body portion 2511 and two catch arms 2512 of the liquid absorbing material 251 are provided in the first pipe section 221, and an extension portion 2513 extends upward from the top surface of the main body portion 2511 and into the second pipe section 222.

The side and end faces of the clamping arm 2512 absorb liquid, and the main body 2511, the extension 2513 and the outer tube 22 are connected in a sealing manner, so that the liquid matrix can be blocked by the liquid absorbing body, and a good liquid guiding effect can be guaranteed. In some embodiments, the distance between the end surfaces of the two catch arms 2512 is smaller than the inner diameter of the first pipe section 221, so that the two catch arms 2512 respectively form a gap with the first pipe section 221, the gap can facilitate liquid discharge and absorption, and can prevent the absorption liquid 251 from contacting the outer pipe 22 and directly conducting heat.

The atomizer body 20 may also include a connector 23 for connecting the atomizer body 20 to the base assembly 10 in some embodiments.

The outer diameter of the lower insertion portion 231 is matched with the hole diameter of the base hole 1110 of the base body 111 of the base 11 so as to penetrate through the neck portion 211 of the housing 21 and then be tightly inserted into the base body 111.

The induction pipe 13 penetrates through the atomizing base 24, the atomizing assembly 25 and the mounting base 26 from bottom to top in sequence, then extends into the inner pipe 27, and is suspended in the inner pipe 27 along the longitudinal direction (i.e. the air outlet end is not in contact with the inner wall surface of the inner pipe 27). By arranging the sensing pipeline 13 in the inner pipe 27, the inherent space in the structure is fully utilized, the design difficulty of the sensing air passage can be reduced, the space is saved, and the cost is reduced. In some embodiments, the upper outlet end of the sensing tube 13 is preferably higher than the plane of the top surface of the mounting seat 26 to prevent the condensate from entering the sensing tube 13 and causing blockage, and also prevent the condensate from entering the main unit 4 through the sensing tube 13. The upper air outlet end of the sensing pipe 13 is preferably lower than the 2/3 height of the inner pipe 27 from bottom to top, so as to prevent the sensing pipe 13 from being too long and easily inclined, which leads to unsmooth air flow and thus reduces the sensing sensitivity.
