[0033] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0034] It should be understood that the terms "front", "rear", "left", "right", "up", "down", "first", "second", etc. are only for the convenience of describing the technical solution of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore cannot be understood as limiting the present invention. It should be noted that when a piece is considered to be "connected" to another piece, it can be directly connected to the other piece or there may be a central piece at the same time. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] Figure 1 and Figure 2 The electronic atomization device 1 in some embodiments of the present invention is shown. The electronic atomization device 1 can be used for heating and atomizing liquid media such as cigarette liquids and liquid medicines. It can be roughly cylindrical and includes a cylindrical atomizer 10 and a cylindrical main unit 20 axially detachably connected to the atomizer 10. The atomizer 10 is used to receive the liquid medium, heat and atomize the liquid medium, and deliver the mist. The main unit 20 is used to power the atomizer 10 and control operations such as turning the entire electronic atomization device 1 on or off. It is understandable that the electronic atomization device 1 is not limited to being cylindrical, and it can also be other shapes such as an elliptical cylinder.

[0036] like Figures 3 to 7As shown, the atomizer 10 in some embodiments may include: a base 11 for detachably connecting to a host 20; a shell 12 with its lower end longitudinally arranged on the top of the base 11; a fixing member 13 of which the lower end extends out of the shell 12 from the inside of the shell 12 and is longitudinally embedded in the base 11 to clamp the shell 12; an atomizer seat 14 located in the shell 12 and with its lower end longitudinally embedded in the fixing member 13; an atomizer assembly 15 located in the shell 12 and mounted on the atomizer seat 14; a mounting seat 16 located in the shell 12 and mounted on the atomizer assembly 15 along the longitudinal direction; an inner tube 17 located in the shell 12 and with its lower end longitudinally embedded in the mounting seat 16; an outer tube 18 located in the shell 12 and with its lower portion sleeved on the fixing member 13, the atomizer seat 14, the atomizer assembly 15 and the mounting seat 16, and with its upper portion surrounding the periphery of the inner tube 17; and a nozzle 19 longitudinally mounted on the shell 12, the inner tube 17 and the upper end of the outer tube 18. Preferably, the base 11 , the housing 12 , the fixing member 13 , the atomizing seat 14 , the atomizing assembly 15 , the mounting seat 16 , the inner tube 17 , the outer tube 18 and the suction nozzle 19 are coaxially assembled together.

[0037] A liquid storage chamber 120 is defined between the inner wall surface of the shell 12 and the outer wall surface of the outer tube 18 to store liquid medium. An atomizing chamber 140 is defined in the atomizing seat 14 for mixing the mist and air generated by the atomizing assembly 15. An air inlet pipe 180 is defined between the inner wall surface of the outer tube 18 and the outer wall surface of the inner tube 17. The air inlet pipe 180 is connected to the atomizing chamber air inlet of the atomizing chamber 140 to allow outside air to enter the atomizing chamber 140. The inner wall surface of the inner tube 17 defines an air outlet pipe 170, which is connected to the atomizing chamber air outlet of the atomizing chamber 140 to guide the mist and air mixture in the atomizing chamber 140. In some embodiments, the suction nozzle 19 is detachably sealed at the upper end of the liquid storage chamber 120 so that the liquid medium can be added.

[0038] For example Figure 3 and Figure 4As shown, in some embodiments, the base 11 may include a conductive cylindrical main body 111, a cylindrical conductive coupling portion 112 integrally connected to the lower portion of the cylindrical main body 111 along the longitudinal direction, a cylindrical first electrode column 113 insulated and longitudinally disposed within the coupling portion 112, and a sensing conduit 114 extending longitudinally through the upper end of the first electrode column 113. The outer diameter of the coupling portion 112 may be smaller than that of the main body 111, and its outer wall may be formed with external threads for threaded connection to the main unit 20. The central through-hole of the first electrode column 113 communicates with the central through-hole of the sensing conduit 114, allowing airflow to enter from the lower end of the first electrode column and exit from the upper end of the sensing conduit 114, forming a first sensing airway. In some embodiments, the sensing conduit 114 may be a cylindrical tube, with its upper outlet extending into the inner tube 17 and longitudinally suspended within the inner tube 17 (i.e., the outlet does not contact the inner wall of the inner tube 17). In some embodiments, the upper air outlet of the sensing conduit 114 is preferably higher than the plane of the top surface of the mounting base 16 to prevent condensation from entering the sensing conduit 114. The upper air outlet of the sensing conduit 114 is preferably lower than two-thirds of the height of the inner tube 17 from bottom to top. This prevents the sensing conduit 114 from being too long and prone to tilting, thereby reducing sensing sensitivity. In some embodiments of the atomizer 10 of the present invention, by providing the sensing conduit 114 on the base 11, the inherent space within the structure is fully utilized to implement the first sensing airway. This reduces the design difficulty of the sensing airway, saves space, and reduces costs.

[0039] In some embodiments, the housing 12 may be cylindrical and made of a transparent or translucent material. A neck portion 121 with a smaller aperture is provided at the lower end of the housing 12. The housing 12 is mounted on the top surface of the main body 111 of the base 11 with the neck portion 121. The inner diameter of the neck portion 121 is comparable to the inner diameter of the main body 111 of the base 11.

[0040] In some embodiments, the fixing member 13 may be cylindrical and include a lower cylindrical insert portion 131 at the bottom, an upper cylindrical insert portion 132 at the top, and a radially outwardly extending flange 133 at the center. The outer diameter of the lower insert portion 131 matches the inner diameter of the main body 111 of the base 11, allowing it to penetrate the neck portion 121 of the housing 12 and fit tightly within the main body 111. The outer diameter of the upper insert portion 132 is larger than that of the lower insert portion 131 and matches the inner diameter of the outer tube 18, allowing it to fit tightly within the outer tube 18. The flange 133 is used to press against the upper side of the neck portion 121 of the housing 12, thereby clamping the neck portion 121 together with the base 11, thereby securing the housing 12 to the base 11.

[0041] In some embodiments, the atomizer seat 14 can be made of a soft material such as soft glue, and may include a main body 141, an insertion portion 142 connected to the lower portion of the main body 141, and a pair of baffles 143 connected to the upper portion of the main body 141. The pair of baffles 143 are arranged on the edge of the top of the main body 141 at intervals. The top surface of the main body 141 is concave to form an atomizing chamber 140. Two air guide grooves 144 are formed on the inner wall surfaces of the two baffles 143 and the atomizing chamber 140. Each air guide groove 144 extends downward from the upper end surface of the corresponding baffle 143 to the bottom surface of the atomizing chamber 140. The insertion portion 142 includes a first slot 1420 located in the middle and two second slots 1422 located on opposite sides of the first slot 1420. The first slot 1420 and the second slot 1422 both extend from the lower end surface of the insertion portion 142 to the main body 141. A connecting hole 1424 is provided between the bottom surface of the first slot 1420 and the bottom surface of the atomizing chamber 140. The diameter of the connecting hole 1424 is adapted to the outer diameter of the sensing pipe 114 (for example, slightly smaller than the outer diameter of the sensing pipe 114), so that the sensing pipe 114 can be tightly inserted therein to prevent leakage. The bottom surface of the atomizing chamber 140 is also recessed to form two third slots 1401. The two third slots 1401 extend from the bottom surface of the atomizing chamber 140 toward the two second slots 1422, respectively, so that a thin wall is formed between the bottom surface of the third slot 1401 and the bottom surface of the corresponding second slot 1422. When the atomizing assembly 15 is installed, its electrode lead 153 can pierce the thin wall and be tightly inserted into the second slot 1422 and the third slot 1401 to prevent leakage.

[0042] In some embodiments, the atomization assembly 15 may include an absorbing liquid 151, a heating element 152 disposed on the absorbing liquid 151, and two electrode leads 153 connected to the heating element 152. The absorbing liquid 151 includes a central through hole 1510 and two clamping arms 1511 respectively disposed on two opposite sides of the upper end of the absorbing liquid 151. The lower portion of the absorbing liquid 151 is embedded in the atomization chamber 140, and a gap is formed between the absorbing liquid 151 and the heating element 152 and the bottom surface of the atomization chamber 140. The central through hole 1510 connects the gap with the upper portion of the absorbing liquid 151. The two clamping arms 1511 are respectively clamped in the two card grooves between the two retaining walls 143 of the atomization seat 14. The two electrode leads 153 are respectively electrically connected to the joint 112 of the base 11 and the first electrode column 113.

[0043] In some embodiments, the mounting base 16 may include a base 161, a mounting portion 162 disposed on the top of the base 161, and a mounting hole 160 longitudinally passing through the base 161 and the mounting portion 162. The base 161 includes two opposite ends 1611 and 1612. Figure 8 and Figure 9The two ends 1611 and 1612 are respectively provided with two air guide holes 1613 and 1614 that extend vertically. These two air guide holes 1613 and 1614 correspond to the two air guide grooves 144 on the atomizer seat 14. Two air guide grooves 1621 and 1622 are respectively provided on opposite sides of the outer wall of the mounting portion 162. These two air guide grooves 1621 and 1622 extend from the upper end of the mounting portion 162 toward the base 161. The top surfaces of the ends 1611 and 1612 are respectively provided with air guide grooves 1615 and 1616, which connect the air guide grooves 1621 and 1622 with the air guide holes 1613 and 1614. The outer diameter of the inner tube 17 is adapted to the aperture of the mounting hole 160 so that its lower end is tightly inserted into the mounting hole 160.

[0044] In some embodiments, the outer tube 18 may include a first tube section 181 at the bottom, a second tube section 182 at the middle, and a third tube section 183 at the top, wherein the inner diameter and outer diameter of the first tube section 181, the second tube section 182, and the third tube section 183 are all reduced, so that the outer tube 18 is in the shape of a stepped shaft. The outer diameter of the first tube section 181 is adapted to the inner diameter of the housing 12 so that the two can be tightly sleeved together. The inner diameter of the first tube section 181 is adapted to the outer diameter of the upper embedded portion 132 of the fixing member 13, the outer diameter of the main body 141 of the atomizing seat 14, the distance between the end faces of the two clamping arms 1511 of the liquid suction 151 of the atomizing assembly 15, and the distance between the end faces of the two ends 1611, 1612 of the mounting seat 16 so that the first tube section 181 can be tightly sleeved on the periphery of these components. The inner diameter of the second pipe section 182 matches the outer diameter of the mounting portion 162 of the mounting seat 16 so that it is tightly sleeved on the mounting portion 162 .

[0045] The inner diameter of the third pipe section 183 is greater than the outer diameter of the inner tube 17, thereby defining an annular air intake duct 180 between the inner wall surface of the third pipe section 183 and the outer wall surface of the inner tube 17. The air intake duct 180 is connected to the air inlet of the atomizing chamber 140 via the air guide grooves 1621, 1622 of the mounting seat 16, the air guide grooves 1615, 1616 of the mounting seat 16, the air guide holes 1613, 1614 of the mounting seat 16, and the air guide groove 144 of the atomizing seat 14. The outer wall surfaces of the second pipe section 182 and the third pipe section 183 and the housing 12 define the liquid storage chamber 120. An opening 1810 is formed on both sides of the top wall of the first pipe section 181, and the two openings 1810 are respectively corresponding to the two clamping arms 1511 of the liquid suction 151 of the atomizing assembly 15, thereby connecting the liquid suction 151 with the liquid storage chamber 120.

[0046] In some embodiments, the suction nozzle 19 may include a main body 191, an insert 192 connected to the lower portion of the main body 191, a suction nozzle 193 connected to the upper portion of the main body 191, and a longitudinally extending air outlet 190. An air inlet 1910 is defined on opposite sides of the main body 191, each of which is connected to the air inlet pipe 180. The insert 192 is removably and hermetically sealed in the annular opening at the upper end of the liquid storage chamber 120. The air outlet 190 is connected to the inner tube 17.

[0047] Here, the air inlet 1910, the air inlet pipe 180, the air guide grooves 1621 and 1622, the air guide grooves 1615 and 1616, the air guide holes 1613 and 1614, the air guide groove 144, the atomizing chamber 140, the mounting hole 160, the air outlet pipe 170, and the air outlet 190 are sequentially connected in series to form a complete mist delivery channel. The air inlet 1910, the air inlet pipe 180, the air guide grooves 1621 and 1622, the air guide grooves 1615 and 1616, the air guide holes 1613 and 1614, and the air guide groove 144 together form an air inlet channel for introducing external air into the mist delivery channel, and the mounting hole 160, the air outlet pipe 170, and the air outlet 190 together form an air outlet channel for delivering a mixture of mist and air.

[0048] like Figure 10 and Figure 11As shown, in some embodiments, the host 20 may include a cylindrical housing 21 with a receiving chamber 210, a connector 22 disposed at the top of the housing 21, and a power supply 23 and an air switch 24 disposed within the receiving chamber 210. The connector 22 is configured to be threadedly connected to the base 11 of the atomizer 10 and may include a cylindrical, conductive connector body 221 and a cylindrical second electrode post 223 insulatedly disposed within the connector body 221. The inner wall of the connector body 221 is internally threaded for threaded connection to the coupling portion 112 of the base 11. The second electrode post 223 is configured to electrically contact the first electrode post 113, with the central through-holes of the two electrodes communicating with each other. The connector body 221 and the second electrode post 223 are electrically connected to the negative and positive electrodes of the power supply 23, respectively, thereby electrically connecting the coupling portion 112 of the base 11 and the first electrode post 113 to the negative and positive electrodes of the power supply 23, respectively. The joint of the shell 21 and the connector 22 may be provided with an air inlet 212 to allow outside air to enter the receiving chamber 210. The air inlet 212, the receiving chamber 210 and the central through hole of the second electrode column 223 together form a second sensing airway. The second sensing airway and the first sensing airway together form the air switch sensing airway of the electronic atomization device 1 for controlling the operation of the air switch 24. Specifically, when the outside inhales air, the airflow passes through the air inlet 212, the receiving chamber 210, the second electrode column 223 in sequence and enters the first electrode column 113 and the sensing pipe 114. During this process, a negative pressure is formed in the receiving chamber 210, and the air switch 24 is activated under the negative pressure.

[0049] When the electronic atomizer device 1 is in operation, the user inhales through the mouthpiece 193 of the nozzle 19. The negative pressure generated by the inhalation is transmitted through the outlet channel of the mist delivery channel to the air switch sensing airway. The air switch 24 is turned on, allowing the power supply device 23 to power the atomizer assembly 15, and the liquid medium begins to be atomized. At the same time, external air enters the atomization chamber 140 through the air inlet channel of the mist delivery channel and mixes with the mist. The mixture of mist and air then enters the user's mouth through the outlet channel of the mist delivery channel.

[0050] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
