The cover body 405 is also provided with a snap buckle 4052 (second snap buckle) on the two side walls arranged opposite to each other along the thickness direction of the electronic atomization device 10. The snap buckle 4052 and the snap groove 401h form a third connecting mechanism, so that the cover body 405 can better hold the third shell 401. The cover 405 is further provided with a via hole 4053 corresponding to the first airflow cavity 4043 and a via hole 4054 corresponding to the second airflow cavity 4044, thereby exposing the first airflow cavity 4043 and the second airflow cavity 4044. The cover 405 is further provided with via holes 4055 corresponding to the sealing holes 4049. The number of via holes 4055 is the same as the number of sealing holes 4049, or the number of second electrode assemblies 4031 and third electrode assemblies 4034. The other end of each electrode can extend outside the cover 405 through the corresponding via hole 4055 or be exposed on the outer surface of the cover 405.

[0100] The display component 406 is installed in the third receiving cavity 401e together with the battery cell 402. The display component 406 is used to display information of the electronic atomization device 10, such as the power level of the battery cell 402, the remaining amount of the liquid matrix, etc.

[0101] Please refer to Figure 8 To understand, the air outside the electronic atomization device 10 can flow into the third accommodating chamber 401e through the air inlet 401g, and then flow into the air hole 4032 (air hole 4035) along the gap between the battery cell 402 and the partition 401b, and then flow into the first air flow chamber 4043 (second air flow chamber 4044) through the air hole 4045 (air hole 4046). For details, please refer to Figure 7 Indicated by the dotted arrow.

[0102] exist Figure 1-Figure 4 In the example, the structures of the first atomizer assembly 200 and the second atomizer assembly 300 are exactly the same. This arrangement facilitates mass production of the atomizer assembly, simplifies the structural design of the power supply assembly 400, and facilitates assembly of the atomizer assembly and the power supply assembly 400. It is understandable that in other examples, it is also feasible to distinguish the first atomizer assembly 200 and the second atomizer assembly 300 through structural design. The specific structure of the first atomizer assembly 200 is described below:

[0103] like Figure 13-16As shown, the first nebulizer assembly 200 includes an nebulizer part 201 and a liquid replenishing part 203 for replenishing the liquid matrix to the nebulizer part 201 .

[0104] The atomizing portion 201 includes a first shell 2011 (first shell). The first shell 2011 is composed of a main shell 20111 and a bottom cover 20112. The main shell 20111 and the bottom cover 20112 can be detachably connected by a connecting mechanism, such as a snap connection. The main shell 20111 defines the upper surface of the first shell 2011, and the bottom cover 20112 defines the lower surface of the first shell 2011. The upper surface of the first shell 2011 is provided with an air outlet 20111a (first air outlet), and the lower surface of the first shell 2011 is provided with an air inlet 20112a (first air inlet). The first shell 2011 has an air flow channel extending from the air inlet 20112a to the air outlet 20111a (reference Figure 16 The main shell 20111 is further provided with a notch groove 20111b.

[0105] Be formed with liquid storage chamber 2012 (first liquid storage chamber) in the first housing 2011, be used to store the first liquid matrix.The first liquid matrix can be the liquid that comprises the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, the first liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the first liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0106] In a preferred embodiment, a liquid storage medium 2013 is provided in the liquid storage chamber 2012. The liquid storage medium 2013 is made of, for example, a fibrous material or a porous material. The liquid storage medium 2013 can absorb and retain the liquid matrix. After injection, when the liquid storage medium 2013 reaches saturation, the liquid matrix content in the liquid storage medium 2013 ranges from 0.1 ml to 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml.

[0107] A sealing member 2014 and a sealing member 2015 are also provided within the first housing 2011. The sealing member 2014 or the sealing member 2015 can be made of silicone. The sealing member 2014 is positioned above the liquid storage medium 2013, while the sealing member 2015 is positioned below the liquid storage medium 2013. The space between the sealing member 2014 or the sealing member 2015 and the liquid storage medium 2013 defines an air portion. The sealing member 2014 and the sealing member 2015 seal the liquid storage chamber 2012. The sealing member 2014 has a through hole 2014a communicating with the air outlet 20111a, and the sealing member 2015 has a through hole 2015a communicating with the air inlet 20112a. A liquid absorbing medium 2016 , such as liquid absorbing cotton, is further provided between the sealing member 2014 and the air outlet 20111 a . The liquid absorbing medium 2016 can be accommodated in the accommodating cavity 2014 b of the sealing member 2014 .

[0108] A connecting tube 2017 is also provided within the first housing 2011. The upper end of the connecting tube 2017 passes through the liquid storage chamber 2012 and is connected to the sealing member 2014. The lower end of the connecting tube 2017 is connected to the sealing member 2015. The connecting tube 2017 is preferably made of a thin, rigid material, such as fiberglass or stainless steel. The liquid storage medium 2013 is sleeved onto the connecting tube 2017. Preferably, the inner diameter of the liquid storage medium 2013 is slightly smaller than the outer diameter of the connecting tube 2017, ensuring that the liquid storage medium 2013 is tightly sleeved onto the connecting tube 2017.

[0109] An atomizer core 2018 is also disposed within the first housing 2011. The atomizer core 2018 includes a capillary guide 2018a and a heating element 2018b. The capillary guide 2018a draws liquid from the liquid storage medium 2013 and transfers the liquid to the heating element 2018b. The heating element 2018b is heated by an electric current and transfers heat to the liquid in contact with the heating element 2018b, thereby heating the liquid and generating an aerosol.

[0110] The capillary liquid guide member 2018a is generally tubular in structure. It is understood that in other examples, it can also be a plate-like structure or other regular or irregular shapes. The capillary liquid guide member 2018a can be made of a flexible fiber material, such as cotton fiber, non-woven fabric, or sponge. Alternatively, in other examples, the capillary liquid guide member 2018a can be a rigid porous body, such as porous ceramic or porous glass. The outer surface of the capillary liquid guide member 2018a has a radially outward protrusion.

[0111] The heating element 2018b is positioned adjacent to the inner surface of the capillary guide 2018a, and may be positioned against the inner surface of the capillary guide 2018a, or partially or completely embedded within the capillary guide 2018a. The heating element 2018b may be a resistive heating mesh, a resistive heating coil, or the like. The heating element 2018b may be made of a material with suitable temperature coefficient of resistance (TCR) characteristics, such as 316 stainless steel, titanium, nickel, or a nickel-chromium alloy. In one example, the heating element 2018b may be formed by winding a sheet or mesh-like substrate. The wound heating element 2018b is a non-closed tubular structure in the circumferential direction, i.e., a tubular structure with side openings extending along the length of the first atomizer assembly 200. Leads are welded or otherwise arranged at both ends of the heating element 2018b. The leads may pass through the seal 2014 and be arranged outside the seal 2014, for example, on the surface of the seal 2014 facing the bottom cover 20112.

[0112] The atomizer core 2018 is disposed within the connecting tube 2017. Preferably, the atomizer core 2018 is coaxially disposed with the connecting tube 2017. The connecting tube 2017 also has a liquid guide port on its sidewall. The liquid storage medium 2013 covers the liquid guide port, and a portion of the capillary liquid guide member 2018a is exposed to the liquid storage chamber 2012 through the liquid guide port. This allows the capillary liquid guide member 2018a to be positioned adjacent to or in contact with the liquid storage medium 2013, thereby allowing the liquid matrix in the liquid storage chamber 2012 to flow through the liquid guide port into the atomizer core 2018, where it is drawn in by the capillary liquid guide member 2018a and atomized by the heating element 2018b to generate an inhalable aerosol.

[0113] The sidewall of the connecting tube 2017 is also provided with a notch extending from the lower end of the connecting tube 2017 toward the upper end of the connecting tube 2017. The protruding portion of the capillary guide 2018a extends into the notch, thereby being exposed to the liquid storage chamber 2012. After assembly, the liquid storage medium 2013 maintains contact with a portion of the protruding portion, thereby facilitating the capillary guide 2018a to absorb the liquid matrix.

[0114] The atomizing portion 201 includes a first electrode assembly 2019, which includes a positive electrode 2019a and a negative electrode 2019b spaced apart. The first electrode assembly 2019 preferably utilizes a resilient electrode, such as a cylindrical POGO pin. One end of the first electrode assembly 2019 is exposed on the lower surface of the first housing 2011. The other end of the first electrode assembly 2019 passes through the bottom cover 20112 and maintains contact with the lead of the heating element 2018b, thereby forming an electrical connection.

[0115] An opening 20112b (first opening) is further provided on the lower surface of the first shell 2011. The first shell 2011 also has a boss 20112c extending from the bottom cover 20112 toward the liquid storage chamber 2012. The boss 20112c is hollow inside and communicates with the opening 20112b.

[0116] A liquid inlet pipe 2020 is also provided within the first housing 2011. The upper end of the liquid inlet pipe 2020 is positioned adjacent to the seal 2014, while the lower end of the liquid inlet pipe 2020 is sleeved onto the boss 20112c. The liquid inlet pipe 2020 and the boss 20112c together define a liquid inlet channel that communicates with the opening 20112b. A liquid inlet port 2020a is provided on the sidewall of the liquid inlet pipe 2020, communicating with the liquid storage chamber 2012.

[0117] A capillary guide 2021 is provided in the liquid inlet channel. The capillary guide 2021 and the atomizer core 2018 are spaced apart in a direction parallel to the lower surface of the first housing 2011 in the first atomizer assembly 200. The cross-section of the capillary guide 2021 gradually decreases from its upper end to its lower end. The upper end of the capillary guide 2021 is positioned near the seal 2014, while its lower end extends toward the opening 20112b. With the capillary guide 2021 extending from top to bottom to the second liquid storage chamber 2032, the liquid matrix in the second liquid storage chamber 2032 can be transferred longitudinally from bottom to top, overcoming gravity, and then laterally to the first liquid storage chamber 2031, effectively controlling the velocity of the liquid matrix and preventing the risk of oversaturation of the liquid matrix in the first liquid storage chamber 2031 and leakage from the airflow inlet.

[0118] In a preferred embodiment, the upper end of the capillary liquid guide member 2021 has a flange that abuts the inner wall of the liquid inlet tube 2020. A gap is formed between the remaining portion of the capillary liquid guide member 2021 and the liquid inlet tube 2020. This facilitates the absorption and retention of a small amount of liquid matrix in this gap during the liquid conduction process, maintaining the continuity of the liquid supply. Furthermore, when the capillary liquid guide member within the first liquid storage chamber 2012 is short of liquid, the liquid is replenished, thereby preventing liquid loss in the atomizer core 218. The material of the capillary liquid guide member 2021 can be referred to the description of the capillary liquid guide member 2018a.

[0119] A snap-in hole 20112d is further provided on the lower surface of the first shell 2011 .

[0120] The rehydration part 203 includes a second housing 2031 (second housing) independent of the first housing 2011. The second housing 2031 is composed of a main housing 20311 and an upper cover 20312. The main housing 20311 and the upper cover 20312 can be detachably connected by a connection mechanism, such as a snap connection.

[0121] Be formed with liquid storage chamber 2032 (second liquid storage chamber) in the second housing 2031, be used to store the second liquid matrix.Similar to the first liquid matrix, the second liquid matrix can be the liquid that comprises the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the second liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0122] It should be noted that the second liquid matrix may have different or identical properties to the first liquid matrix. For example, the second liquid matrix may have different components than the first liquid matrix, or the second liquid matrix may have different concentrations than the first liquid matrix. In some examples, the second liquid matrix and the first liquid matrix have the same composition or type, and the second liquid matrix in the second liquid storage chamber 2032 serves as a liquid replenishment source for the first liquid storage chamber 2012.

[0123] The volume of the liquid storage chamber 2032 is greater than that of the liquid storage chamber 2012. Generally, the volume of the second liquid matrix stored in the liquid storage chamber 2032 is between 2 ml and 10 ml, such as 4 ml, 5 ml, 6 ml, 8 ml, etc.

[0124] A sealing member 2033 is provided in the second housing 2031. The sealing member 2033 is made of silicone material and is provided between the main housing 20311 and the upper cover 20312, thereby sealing the liquid storage chamber 2032.

[0125] The upper surface of the second housing 2031 has a protruding connecting portion 20312a, and the connecting portion 20312a is provided with a liquid outlet 20312b that communicates with the liquid storage chamber 2032. A sealing member 2034 is sleeved on the connecting portion 20312a.

[0126] A snap-fit ​​buckle 20312c (first snap-fit ​​buckle) is also provided on the upper surface of the second housing 2031. The snap-fit ​​buckle 20312c and the snap-fit ​​hole 20112d form a first connection mechanism, thereby connecting the second housing 2031 to the first housing 2011. The second housing 2031 and the first housing 2011 can be connected in a non-detachable or detachable manner.

[0127] When the second housing 2031 is connected to the first housing 2011, the connecting portion 20312a extends into the liquid inlet channel through the opening 20112b. The lower end of the capillary liquid guide 2021 is inserted into the second housing 2031 through the liquid outlet 20312b. The sealing member 2033 is located between the boss 20112c and the connecting portion 20312a. In this way, the second liquid matrix stored in the liquid storage chamber 2032 can flow through the liquid outlet 20312b to the liquid inlet channel and then to the liquid storage chamber 2012, thereby replenishing the liquid storage chamber 2012. The sealing member 2033 prevents leakage of the liquid matrix in the liquid inlet channel. The capillary liquid guide 2021 effectively guides the second liquid matrix stored in the liquid storage chamber 2032 to the liquid storage chamber 2012. It is understandable that the connecting portion 20312a does not extend into the liquid inlet channel, and it is also feasible that the liquid outlet 20312b is aligned and connected with the opening 20112b.

[0128] When the second housing 2031 is connected to the first housing 2011, the air inlet 20112a and the first electrode assembly 2019 are not blocked by the second housing 2031. In other words, the second housing 2031 avoids the air inlet 20112a and the first electrode assembly 2019. The second housing 2031 is connected to the lower surface (first outer surface) of the first housing 2011, or the second housing 2031 is connected to a portion of the lower surface of the first housing 2011. The air inlet 20112a is provided on the first portion G of the lower surface of the first housing 2011, and one end of the first electrode assembly 2019 is also exposed on the first portion G of the lower surface of the first housing 2011. The second housing 2031 blocks the second portion F of the lower surface of the first housing 2011 and avoids the first portion G of the lower surface of the first housing 2011, thereby exposing the air inlet 20112a and the first electrode assembly 2019 to the first portion G of the lower surface of the first housing 2011.

[0129] It is understood that before the second housing 2031 is connected to the first housing 2011, the opening 20112b, the liquid outlet 20312b, and the air outlet 20111a can be sealed with a sealing member to prevent leakage of the liquid matrix and facilitate product transportation. The sealing member can be made of silicone. After receiving the atomization unit 201 and the liquid replenishment unit 203, the user can remove the sealing member and then assemble the device.

[0130] It should be noted that, in combination with the above-mentioned specific structure of the first atomizer assembly 200, those skilled in the art can understand the second atomizer assembly 300 with the same structural design. It is understandable that the liquid matrix in the first atomizer assembly 200 and the liquid matrix in the second atomizer assembly 300 can be different or the same.

[0131] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c, the second shell 2031 of the first atomizer assembly 200 is completely contained in the third shell 401, and the first shell 2011 of the first atomizer assembly 200 is at least partially exposed outside the third shell 401. At least part of the first shell 2011 exposed outside the third shell 401 is convenient for the user to pinch and thus remove the first atomizer assembly 200 from the first accommodating chamber 401c. In order to facilitate the user to view the remaining amount of liquid matrix in the liquid storage chamber 2032, a visual window is provided on the part of the third shell 401 corresponding to the first accommodating chamber 401c. The visual window can be formed by a transparent material on the third shell 401, or it can be an opening on the third shell 401. It is understandable that when the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the above-mentioned characteristics are also present, which will not be described in detail here.

[0132] In a preferred embodiment, when the first atomizer assembly 200 is installed in the first accommodating chamber 401c, the second housing 2031 of the first atomizer assembly 200 is at least partially located in the first accommodating chamber 401c, while the first housing 2011 of the first atomizer assembly 200 can be partially accommodated between the partition E and the upper opening of the third housing 401, with a portion of the first housing 2011 exposed outside the third housing 401. The above characteristics also exist when the second atomizer assembly 300 is installed in the second accommodating chamber 401d, and will not be described in detail here.

[0133] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c, the first electrode assembly 2019 of the first atomizer assembly 200 maintains contact with the third electrode assembly 4034 in a one-to-one correspondence, thereby forming an electrical connection. When the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the electrode assembly of the second atomizer assembly 300 maintains contact with the second electrode assembly 4031 in a one-to-one correspondence, thereby forming an electrical connection.

[0134] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c and the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the first portion of the first outer surface of the first shell 2011 of the first atomizer assembly 200 and the first portion of the first outer surface of the shell of the atomizing portion of the second atomizer assembly 300 both abut against the cover 405, that is, abut against the partition E. Because the rehydration portions and the first electrode assembly of the first atomizer assembly 200 and the second atomizer assembly 300 are disposed on the same side surface, that is, the first outer surface, this helps save space within the power supply assembly and reduces the volume of the entire electronic atomizer device. In addition, during installation, the liquid replenishing parts of the first atomizing assembly 200 and the second atomizing assembly 300 are correspondingly accommodated in the first accommodating cavity 401c and the second accommodating cavity 401d, and the first part of the first outer surface is docked with the spacer E. The proximal surface of the third electrode assembly provided in the spacer E is significantly higher than the bottom of the first accommodating cavity 401c and the second accommodating cavity 401d, thereby effectively preventing the liquid matrix in the atomizing part of the first atomizing assembly 200 and the second atomizing assembly 300 from leaking to the circuit board on the spacer E. In this way, the first part G of the lower surface of the first shell 2011 in the first atomizer assembly 200 can block the second air flow cavity 4044 to form a closed chamber, so that the air inlet 20112a of the first atomizer assembly 200 is connected to the second air flow cavity 4044, and the airflow in the second air flow cavity 4044 can flow into the first atomizer assembly 200 through the air inlet 20112a of the first atomizer assembly 200, mix with the aerosol generated by the heating element 2018b, and then flow out from the air outlet 20111a of the first atomizer assembly 200. Correspondingly, the first part of the lower surface of the shell of the atomizing part in the second atomizing assembly 300 can block the first airflow cavity 4043 to form a closed chamber, so that the air inlet of the second atomizing assembly 300 is connected to the first airflow cavity 4043, and the airflow in the first airflow cavity 4043 can flow into the second atomizing assembly 300 through the air inlet of the second atomizing assembly 300, and after mixing with the aerosol generated by the heating element in the second atomizing assembly 300, flow out from the air outlet of the second atomizing assembly 300.

[0135] When the nozzle assembly 100 is connected to the power supply assembly 400 , at least a portion of the first shell 2011 exposed outside the third shell 401 and at least a portion of the second atomizer assembly 300 exposed outside the third shell 401 are both accommodated in the cavity in the cover 102 .

[0136] When the first atomizer assembly 200 is installed in the first accommodating chamber 401c and the second atomizer assembly 300 is installed in the second accommodating chamber 401d, the notched groove 20111b of the first atomizer assembly 200 and the notched groove of the second atomizer assembly 300 enclose a snap-fit ​​groove A (second snap-fit ​​groove). When the nozzle assembly 100 is connected to the power supply assembly 400, the lower end of the connection hole 102c extends into the cavity within the cover body 102 to form a protrusion that can snap into the snap-fit ​​groove A, thereby effectively holding the first atomizer assembly 200 and the second atomizer assembly 300.

[0137] When the nozzle assembly 100 is connected to the power supply assembly 400, the air outlet 20111a of the first atomizer assembly 200 is aligned and connected with the air hole 102a, and the air outlet of the second atomizer assembly 300 is aligned and connected with the air hole 102b, so that the aerosol generated by the first atomizer assembly 200 or the second atomizer assembly 300 can be inhaled by the user through the air outlet channel 101b1.

[0138] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of this application. The purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive. In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of this application; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
