[0055] As Figures 1-5 The electronic atomization device 10 provided by the embodiment of the present application comprises a power supply assembly 100, a first atomization assembly 200, a second atomization assembly 300, a nosepiece 400, and a cover 500. In the drawings, the X direction represents the width direction of the electronic atomization device 10, the Y direction represents the thickness direction of the electronic atomization device 10, and the Z direction represents the length direction of the electronic atomization device 10.

[0056] Please refer to Figures 6-11For better understanding, the power assembly 100 comprises a first housing 101 which is substantially cuboid, and the first housing 101 defines part of the side wall and the bottom wall of the nasal electronic atomization device 10.

[0057] The first housing 101 is provided with a first accommodating cavity 102, a second accommodating cavity 103 and an electronic cavity 104. The first accommodating cavity 102, the second accommodating cavity 103 and the electronic cavity 104 are spaced from each other, for example, by a partition or the like.

[0058] The first accommodating cavity 102 and the second accommodating cavity 103 are arranged side by side along the width direction of the nasal electronic atomization device 10. Both the first accommodating cavity 102 and the second accommodating cavity 103 have an opening, which can be arranged at the top of the first housing 101, and the opening of the first accommodating cavity 102 is spaced from the opening of the second accommodating cavity 103. The first atomization assembly 200 is removably received or inserted in the first accommodating cavity 102 at least partially through the opening of the first accommodating cavity 102, and the second atomization assembly 300 is removably received or inserted in the second accommodating cavity 103 at least partially through the opening of the second accommodating cavity 103. That is, the first atomization assembly 200 and the second atomization assembly 300 are inserted into the corresponding accommodating cavities from top to bottom along the length direction of the nasal electronic atomization device 10, and the first atomization assembly 200 and the second atomization assembly 300 are also arranged in sequence along the width direction of the nasal electronic atomization device 10.

[0059] In other examples, the first accommodating cavity 102 and the second accommodating cavity 103 are partially or wholly communicated, which is also feasible.

[0060] In other examples, the opening of the first accommodating cavity 102 or the second accommodating cavity 103 is arranged on the side wall of the first housing 101, for example, the opening can be a slot extending longitudinally on the side wall, and it is also feasible that the first atomization assembly 200 or the second atomization assembly 300 can be assembled into the corresponding accommodating cavity from left to right or from right to left along the width direction of the nasal electronic atomization device 10 while maintaining a longitudinal posture.

[0061] In a preferred implementation, a first part of the first atomization assembly 200 is received in the first accommodating cavity 102, and a second part of the first atomization assembly 200 is exposed outside the first housing 101, that is, the first atomization assembly 200 partially extends outside the first housing 101; a first part of the second atomization assembly 300 is received in the second accommodating cavity 103, and a second part of the second atomization assembly 300 is exposed outside the first housing 101, that is, the second atomization assembly 300 partially extends outside the first housing 101. In this way, the user can extract the first atomization assembly 200 from the first accommodating cavity 102 through the part of the first atomization assembly 200 exposed outside the first housing 101, and the second atomization assembly 300 is also the same.

[0062] The first accommodating cavity 102 is provided with a first electrode assembly 102a, at least a part of the first electrode assembly 102a being exposed on the cavity wall of the first accommodating cavity 102. It can be understood that the first electrode assembly 102a includes positive and negative electrode connecting members arranged at intervals. The first electrode assembly 102a can be a common POGO PIN, or other elastic or non-elastic conductive member. The first accommodating cavity 102 is also provided with a first air outlet 102b. In a preferred implementation, the positive electrode connecting member, the first air outlet 102b and the negative electrode connecting member are arranged on the bottom cavity wall of the first accommodating cavity 102, and the positive electrode connecting member, the first air outlet 102b and the negative electrode connecting member are arranged in sequence along the thickness direction of the nasal inhalation electronic atomization device 10, and the first air outlet 102b is located between the positive electrode connecting member and the negative electrode connecting member. When the first atomization assembly 200 is received in the first accommodating cavity 102, the first electrode assembly 102a can realize electrical connection between the power supply assembly 100 and the first atomization assembly 200; the first air outlet 102b can realize fluid communication between the power supply assembly 100 and the first atomization assembly 200, so that air can flow into the first atomization assembly 200. Similarly, the second accommodating cavity 103 is provided with a second electrode assembly 103a and a second air outlet 103b, and the specific structural design can refer to the description of the first electrode assembly 102a and the first air outlet 102b.

[0063] The electronic cavity 104 is located below the first accommodating cavity 102 and the second accommodating cavity 103, that is, the electronic cavity 104 is located between any one of the first accommodating cavity 102 and the second accommodating cavity 103 and the bottom of the first shell 101. The electronic cavity 104 is provided with an electric core 1041, a circuit board 1042 and an air flow sensor 1043.

[0064] The electric core 1041 is used to provide power. The electric core 1041 can be a primary battery or a rechargeable battery. In an example, the electronic cavity 104 is also provided with a charging interface, which is exposed through the opening 104a of the side wall of the nasal inhalation electronic atomization device 10, and the electric core can be charged through the charging interface.

[0065] The circuit board 1042 is provided with a control unit, which is used to control the overall operation of the nasal inhalation electronic atomization device 10. The control unit can not only control the operation of the electric core 1041, the first atomization assembly 200, the second atomization assembly 300 and the like, but also control the operation of other components in the nasal inhalation electronic atomization device 10.

[0066] The circuit board 1042 is horizontally arranged in the electronic cavity 104, the battery cell 1041 is located between the circuit board 1042 and the bottom wall of the electronic vaping device 10, and the airflow sensor 1043 is arranged on the circuit board 1042 and on the surface of the circuit board 1042 facing away from the bottom wall of the electronic vaping device 10. The charging interface can also be arranged on the surface. One end of the first electrode assembly 102a can be connected to the circuit board 1042, and the other end of the first electrode assembly 102a extends into the first accommodating cavity 102. Similarly, one end of the second electrode assembly 103a can be connected to the circuit board 1042, and the other end of the second electrode assembly 103a extends into the second accommodating cavity 103.

[0067] In a preferred implementation, the airflow sensor 1043 can adopt a common microphone assembly. One sensing surface of the airflow sensor 1043 is in communication with the electronic cavity 104, and the electronic cavity 104 is in communication with the outside through the through hole 104b in the side wall of the electronic vaping device 10, so that one sensing surface of the airflow sensor 1043 is in communication with the external atmospheric pressure. The other sensing surface of the airflow sensor 1043 is in communication with the airflow passage in the power supply assembly 100. In this way, during the process of inhaling the electronic vaping device 10, the airflow sensor 1043 can sense the change of airflow in the airflow passage.

[0068] The first shell 101 further comprises an airflow cavity. The airflow cavity defines an airflow passage extending from the air inlet 105a to the first air outlet 102b and / or the second air outlet 103b, i.e. provides a path for air to enter the first accommodating cavity 102 and the second accommodating cavity 103, respectively. The airflow cavity is used to guide air to enter the first accommodating cavity 102 or the second accommodating cavity 103 in a direction opposite to the opening of the first accommodating cavity 102 or the second accommodating cavity 103. The airflow cavity comprises a first airflow cavity 105 and a second airflow cavity 106.

[0069] The first airflow cavity 105 or the second airflow cavity 106 is in airtight sealing with the first accommodating cavity 102, the second accommodating cavity 103 and the electronic cavity 104, which can be achieved by a partition, a sealing member or the like.

[0070] The first airflow cavity 105 extends along the length of the first housing 101 and is located between the first receiving cavity 102 and the second receiving cavity 103. That is, the first airflow cavity 105, the first receiving cavity 102, and the second receiving cavity 103 are arranged side by side along the width of the first housing 101. The second airflow cavity 106 extends along the width or thickness of the first housing 101 and is located between any one of the first receiving cavity 102, the second receiving cavity 103, and the first airflow cavity 105 and the bottom of the first housing 101. The electronic cavity 104 is located between the second airflow cavity 106 and the bottom of the first housing 101.

[0071] The first airflow chamber 105 is connected to the external atmosphere through the air inlet 105a on the side wall of the first housing 101. The first airflow chamber 105 is connected to the second airflow chamber 106 through the air outlet 107. The second airflow chamber 106 is connected to the first air outlet 102b and the second air outlet 103b. In this way, external air can flow into the first airflow chamber 105 through the air inlet 105a, and then flow in a different direction along the length of the nasal inhalation electronic atomizing device 10 towards the second airflow chamber 106. After passing through the air outlet 107, it flows in a different direction into the second airflow chamber 106, and finally flows to the left or right along the width of the nasal inhalation electronic atomizing device 10, that is, it flows out from the first air outlet 102b or the second air outlet 103b, thereby forming the airflow channel of the power supply component 100 (refer to the dashed arrow S11 in the figure). A sensing channel 1043a is provided between the electronic cavity 104 and the second airflow cavity 106. Another sensing surface of the airflow sensor 1043 is connected to the second airflow cavity 106 through the sensing channel 1043a. In this way, during the inhalation process of the nasal inhalation electronic atomizing device 10, the airflow sensor 1043 can sense the changes in airflow in the airflow channel.

[0072] The vent 107 is located near the front or rear sidewall of the first housing 101, that is, the front or rear sidewall of the first housing 101 defines at least a portion of the boundary of the vent 107.

[0073] Both the first atomizing component 200 and the second atomizing component 300 are used to atomize the liquid matrix to generate an aerosol.

[0074] exist Figures 1-5 In the example, the first atomizing component 200 and the second atomizing component 300 have the same structure. This arrangement facilitates mass production of the atomizing components, simplifies the structural design of the power supply component 100, and facilitates the assembly of the atomizing components and the power supply component 100. It is understandable that in other examples, it is also feasible to distinguish the first atomizing component 200 and the second atomizing component 300 through structural design, or to adopt different structures for the two.

[0075] The following takes the first atomization assembly 200 and the second atomization assembly 300 as an example, and the specific structure of the first atomization assembly 200 is described.

[0076] As shown in Figures 12 to 20 , the first atomization assembly 200 includes:

[0077] The main shell 201 is generally cylindrical. The main shell 201 has a proximal end and a distal end opposite along the length direction. The proximal end is provided with an aerosol outlet 201a for the aerosol to flow out, and the distal end is configured as one end combined with the power assembly 100. The distal end of the main shell 201 is open, and a detachable bottom cover 202 is mounted thereon. After being combined with the bottom cover 202, the main shell 201 and the bottom cover 202 jointly define the shell (second shell) of the first atomization assembly 200, and the shell inside the first atomization assembly 200 is hollow and provided with necessary functional devices for storing and atomizing the liquid substrate; through the opening of the main shell 201, each necessary functional component can be installed inside the shell of the first atomization assembly 200.

[0078] Please understand in combination with Figure 16 , the bottom cover 202 has a cavity 202a, and the bottom cover 202 is provided with a third electrode assembly including a first electrode column 203 and a second electrode column 204. Specifically, the bottom wall of the cavity 202a has two convex columns. One of the convex columns is provided with a through hole to form a first electrode hole 202b, and the conductive part 203a of the first electrode column 203 is at least partially received in the first electrode hole 202b, and the connecting part 203b of the first electrode column 203 is exposed on the outer surface of the bottom cover 202; the other convex column is provided with another through hole to form a second electrode hole 202c, and the conductive part of the second electrode column 204 is at least partially received in the second electrode hole 202c, and the connecting part of the second electrode column 204 is exposed on the outer surface of the bottom cover 202. Through the first electrode column 203 and the second electrode column 204, the first atomization assembly 200 can be electrically connected with the power assembly 100. Another convex column is also provided between the above two convex columns, and the other convex column is provided with a through hole to form an air inlet 202d, and the shell of the first atomization assembly 200 has an air flow channel extending from the air inlet 202d to the aerosol outlet 201a. Specifically, in the suction, the external air enters into the first atomization assembly 200 through the air inlet 202d, and after mixing with the generated aerosol, it flows out of the first atomization assembly 200 through the aerosol outlet 201a (as shown by the dashed arrow S12 in the figure). The above-mentioned another convex column can also avoid that the liquid substrate flowing into the cavity 202a directly flows out of the air inlet 202d to the power assembly 100.

[0079] The main shell 201 and the bottom cover 202 can be detachably connected. In a preferred embodiment, the main shell 201 is provided with a clamping hole 201b, and the bottom cover 202 is provided with a clamping buckle 202e which is buckled with the clamping hole 201b.

[0080] The main shell 201 is further provided with a notch groove 201c, and the bottom cover 202 is provided with a protrusion 202f. When the main shell 201 and the bottom cover 202 are assembled, the notch groove 201c can be aligned with the protrusion 202f and then assembled. After assembly, the protrusion 202f is clamped in the notch groove 201c. Through the notch groove 201c and the protrusion 202f, the positioning effect can be achieved, which is convenient for assembly.

[0081] The shell of the first atomization assembly 200 is provided with a liquid storage cavity A, a second liquid guide element 205, a heating element 206, a first lead wire 207, a second lead wire 208, a connecting pipe 209, a first liquid guide element 210, a bracket 211 and a sealing element 212.

[0082] The main shell 201 further has an axially extending transmission pipe 201d. The space between the outer surface of the transmission pipe 201d and the inner surface of the main shell 201 forms a liquid storage cavity A for storing a liquid substrate. The hollow part in the transmission pipe 201d forms a part of the airflow channel or at least part of the aerosol channel. One end of the transmission pipe 201d communicates with the aerosol outlet 201a, so as to transmit the aerosol generated by the atomization of the heating element 206 to the aerosol outlet 201a. In a preferred embodiment, the transmission pipe 201d and the main shell 201 are integrally molded by using a moldable material, so that the liquid storage cavity A formed after preparation is open or open towards the distal end.

[0083] The second liquid guide element 205 and the heating element 206 constitute an atomization core which can atomize the liquid substrate and generate aerosol. Specifically, the second liquid guide element 205 can absorb the liquid substrate and deliver the absorbed liquid substrate to the heating element 206. The second liquid guide element 205 is generally in a tubular structure. It can be understood that in other examples, it can also be in a plate structure or other regular or irregular shapes. The second liquid guide element 205 can be made of flexible fiber material, such as cotton fiber, non-woven fabric or sponge, etc. Alternatively, in other examples, the second liquid guide element 205 can also be a rigid porous body, such as porous ceramic, porous glass, etc. The outer surface of the second liquid guide element 205 has a radially outwardly extending protruding portion 205a.

[0084] The heating element 206 can be heated by an electric current supply and transfer heat to the liquid substrate in contact with the heating element 206 to heat the liquid substrate and further generate aerosol. The heating element 206 is arranged close to the inner side surface of the second liquid guide element 205, can be attached to the inner side surface of the second liquid guide element 205, or partially or completely embedded in the second liquid guide element 205. The heating element 206 can be a resistance heating net, a resistance heating coil, etc. The heating element 206 can be made of a material with suitable resistance temperature coefficient characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In an example, the heating element 206 can be wound from a sheet or net substrate, and the wound heating element 206 is a non-closed tubular structure in the circumferential direction, i.e. a tubular structure with a side opening extending along the length direction or axial direction of the first atomization assembly 200.

[0085] The two ends of the heating element 206 are welded or arranged with a first lead wire 207 and a second lead wire 208, the first lead wire 207 keeps contact with the conductive part 203a of the first electrode column 203 to form an electrical connection, and the second lead wire 208 keeps contact with the conductive part of the second electrode column 204 to form an electrical connection. Specifically, the first lead wire 207 and the second lead wire 208 extend from the bottom of the bracket 211 and are bent to be kept on the bottom of the bracket 211, and the conductive part 203a of the first electrode column 203 and the conductive part of the second electrode column 204 abut on the bottom of the bracket 211 to keep contact with the first lead wire 207 and the second lead wire 208.

[0086] The second liquid guide element 205 and the heating element 206 are both accommodated in the connecting pipe 209. The first liquid guide element 210 is arranged on the outer surface of the connecting pipe 209, specifically, the tubular structure of the first liquid guide element 210 is sleeved on the connecting pipe 209, preferably, the inner diameter of the first liquid guide element 210 is slightly smaller than the outer diameter of the connecting pipe 209, so that the first liquid guide element 210 is tightly sleeved on the connecting pipe 209. The connecting pipe 209 is preferably made of a relatively thin rigid material, such as glass fiber material, stainless steel, etc. Preferably, the atomization core is coaxially arranged with the connecting pipe 209. The sidewall of the connecting pipe 209 also has a liquid guide opening 209a, the first liquid guide element 210 covers the liquid guide opening 209a, and part of the second liquid guide element 205 is exposed in the liquid storage cavity A through the liquid guide opening 209a, so that the part of the second liquid guide element 205 is arranged close to or in contact with the first liquid guide element 210, and the liquid substrate in the liquid storage cavity A can be sucked by the first liquid guide element 210 to flow into the atomization core through the liquid guide opening 209a, i.e. be sucked by the second liquid guide element 205, and be atomized by the heating element 206 to generate the inhalable aerosol. Advantageously, the liquid substrate is sucked by the second liquid guide element 205 from the first liquid guide element 210, which can avoid the liquid substrate being excessively or too quickly transferred to the heating element 206.

[0087] In an example, the first liquid guiding element 210 can be made of a flexible organic porous material, which has moderate flexibility and rigidity. In an implementation, the first liquid guiding element 210 has a modulus of elasticity or rigidity smaller than that of the bracket 211 and larger than that of the second liquid guiding element 205. Specifically, the first liquid guiding element 210 is a hard cotton wool with a Shore hardness of 20-70A. In an alternative implementation, the first liquid guiding element 210 is a hard cotton wool including oriented polyester fibers, or a hard cotton wool made of filamentous polyurethane or a foamed cotton, etc.

[0088] The side wall of the connecting pipe 209 is further provided with a notch groove 209b extending from the lower end of the connecting pipe 209 towards the upper end of the connecting pipe 209. The protruding portion 205a of the second liquid guiding element 205 extends into the notch groove 209b and is thus exposed in the liquid storage cavity A. After assembly, the first liquid guiding element 210 is in contact with the protruding portion 205a, which facilitates the second liquid guiding element 205 to absorb the liquid substrate.

[0089] Please understand that Figures 17-19 The bracket 211 is preferably made of a hard material, for example, in some examples, the bracket 211 can be made of a plastic material.

[0090] The bracket 211 and the bottom cover 202 can be connected in a snap-fit manner. In a preferred implementation, the bottom cover 202 is further provided with a clamping hole 202g, and the bracket 211 is provided with a clamping buckle 211a which is snap-fitted with the clamping hole 202g.

[0091] The bottom of the bracket 211 can be supported on the bottom cover 202. In a preferred implementation, the bottom cover 202 is further provided with a support portion 202h which is located in the cavity 202a and protrudes from the bottom wall of the cavity 202a, and the bottom of the bracket 211 can be supported on the support portion 202h.

[0092] The bracket 211 has a substantially cylindrical structure, and the outside air flows into the cavity 202a through the air inlet 202d, then flows into the bracket 211, mixes with the aerosol generated by the atomizing core, and then flows into the transmission pipe 201d, and finally flows out from the aerosol outlet 201a.

[0093] At least part of the connecting pipe 209 is accommodated in the bracket 211. Specifically, the inner surface of the bracket 211 has a boss 211b, for example, extending radially inward from the inner surface of the bracket 211. The upper end of the connecting pipe 209 is connected with the transmission pipe 201d, for example, the upper end of the connecting pipe 209 is sleeved on the transmission pipe 201d; the lower end of the connecting pipe 209 is inserted into the connecting pipe 209 and abuts against the boss 211b. Further, the boss 211b also has a supporting portion 211c extending axially toward the direction of the aerosol outlet 201a, when the lower end of the connecting pipe 209 is inserted into the connecting pipe 209, the second liquid guide element 205 can be supported by the supporting portion 211c.

[0094] At least part of the first liquid guide element 210 is accommodated in the bracket 211. Specifically, the bracket 211 also has a supporting portion 211d extending axially toward the direction of the aerosol outlet 201a. The first liquid guide element 210 is supported by the supporting portion 211d.

[0095] Please understand in combination Figure 20 The sealing member 212 can be made of a flexible material, for example, silicone or the like. The sealing member 212 is in a cylindrical shape. The lower end of the sealing member 212 is sleeved on the bottom cover 202 and the end face of the lower end of the sealing member 212 abuts against the step 202i of the bottom cover 202. The bracket 211 is at least partially accommodated in the sealing member 212, and in a preferred implementation, the bracket 211 is located in the sealing member 212. When the main shell 201 is connected with the bottom cover 202, part of the sealing member 212 is clamped between the main shell 201 and the bottom cover 202, and part of the sealing member 212 is clamped between the main shell 201 and the bracket 211, thereby achieving sealing.

[0096] Further, the outer surface of the sealing member 212 has one or more protruding sealing rings 212a, which can better form a seal between the main shell 201 and the bottom cover 202 and / or between the main shell 201 and the bracket 211.

[0097] Further, the inner surface of the sealing member 212 has a step 212b. When the bracket 211 is assembled in the sealing member 212, the end face of the upper end of the bracket 211 can abut against the step 212b, so that the bracket 211 can be axially limited, achieving the effect of being assembled in place.

[0098] In order to balance the air pressure between the liquid storage cavity A and the outside, when the air pressure in the liquid storage cavity A is low due to the consumption of the liquid substrate, external air can be supplied to the liquid storage cavity A to balance the air pressure between the liquid storage cavity A and the outside. In a specific implementation, the inner surface of the support 211 is further provided with a vent groove 212e, one end of the vent groove 212e is in communication with the capillary groove or the groove 211g on the outer surface of the support 211 through the through hole 211f, and the other end of the vent groove 212e extends towards or is arranged close to the liquid storage cavity A. The capillary groove or the groove 211g can be in communication with the airflow channel in the housing of the first atomization assembly 200, thereby being in communication with the outside of the atomizer 10; for example, the capillary groove or the groove 211g extends to a position close to the cavity 202a along the circumferential and / or axial direction of the support 211, thereby being in communication with the cavity 202a; or a plurality of capillary grooves or grooves 211g are arranged on the outer surface of the support 211, the plurality of capillary grooves or grooves 211g are arranged along the circumferential and / or axial direction of the support 211, and one of the plurality of capillary grooves or grooves 211g that are in communication with each other and close to the cavity 202a is in communication with the cavity 202a. In this way, when the air pressure in the liquid storage cavity A is low due to the consumption of the liquid substrate, external air can be supplied to the liquid storage cavity A through the capillary groove or the groove 211g, the through hole 211f and the vent groove 212e, thereby balancing the air pressure between the liquid storage cavity A and the outside.

[0099] It should be noted that, in combination with the above specific structure of the first atomization assembly 200, those skilled in the art can understand the second atomization assembly 300 with the same structure design. It can be understood that the liquid substrate (first liquid substrate) stored in the liquid storage cavity A in the first atomization assembly 200 can be different from the liquid substrate (second liquid substrate) stored in the liquid storage cavity in the second atomization assembly 300, or can be the same. For example, in some examples, the second liquid substrate and the first liquid substrate are different in composition, or the second liquid substrate and the first liquid substrate are different in concentration. For example, in other examples, the second liquid substrate and the first liquid substrate are exactly the same in composition, and the second liquid substrate can be part of a certain liquid formula, and the first liquid substrate can be another part of a certain liquid formula.

[0100] The nosepiece 400 is made of a flexible material, such as a food-grade silicone material. The nosepiece 400 includes a first nosepiece 401 and a second nosepiece 402. The first nosepiece 401 and the second nosepiece 402 can be integrally formed, for example Figures 1-5 The first nosepiece 401 and the second nosepiece 402 can also be independent of each other. The nosepiece 400 is detachably connected to the first atomization assembly 200 or the second atomization assembly 300, for example Figures 1-5 The first nosepiece 401 and the second nosepiece 402 can also be independent of each other. The nosepiece 400 is detachably connected to the first atomization assembly 200 or the second atomization assembly 300, for example

[0101] In an example, the first nosepiece 401 and the second nosepiece 402 each has a nosepiece port including a nosepiece air inlet, a nosepiece air outlet, and a nosepiece air passage extending from the nosepiece air inlet to the nosepiece air outlet. One end of the first nosepiece 401 is sleeved on the first atomization assembly 200, for example, on the portion of the first atomization assembly 200 exposed outside the first housing 101, and the nosepiece air inlet of the first nosepiece 401 is in communication with the aerosol outlet 201a of the first atomization assembly 200; one end of the second nosepiece 402 is sleeved on the second atomization assembly 300, for example, on the portion of the second atomization assembly 300 exposed outside the first housing 101, and the nosepiece air inlet of the second nosepiece 402 is in communication with the air outlet 201 of the second atomization assembly 300. The other end of the first nosepiece 401 or the second nosepiece 402 includes a curved surface or a spherical cap surface matching the shape of the user's nasal cavity, and the other end of the first nosepiece 401 or the second nosepiece 402 can be close to the user's nasal cavity, so that the nosepiece air outlet of the first nosepiece 401 or the second nosepiece 402 is in communication with the nasal cavity, that is, the nosepiece air outlet of the first nosepiece 401 transmits the aerosol generated by the first atomization assembly 200 into one of the user's nasal cavities, and the nosepiece air outlet of the second nosepiece 402 transmits the aerosol generated by the second atomization assembly 300 into the other of the user's nasal cavities.

[0102] The distance d between the nosepiece air outlet (at the center position) of the first nosepiece 401 and the nosepiece air outlet (at the center position) of the second nosepiece 402 is the distance between the two nasal cavities of an adult; generally, the distance d is between 15 mm and 25 mm, or between 15 mm and 24 mm, or between 15 mm and 23 mm, or between 15 mm and 22 mm, or between 16 mm and 22 mm, or between 17 mm and 22 mm, or between 18 mm and 22 mm, or between 19 mm and 22 mm. In practice, nosepieces 400 with different distances d and integrally formed can be configured for users to choose; or through structural design, the user can dynamically adjust the distance d, thereby facilitating the user's use.

[0103] The cover 500 is detachably connected with the power assembly 100, and the cover 500 defines another part of the side wall and the top wall of the nosepiece electronic atomization device 10. When the cover 500 is connected with the power assembly 100, the first atomization assembly 200 and the second atomization assembly 300 are completely accommodated in the nosepiece electronic atomization device 10.

[0104] In a preferred embodiment, the cover 500 is snap-connected with the power assembly 100. For example, the cover 500 is provided with a snap buckle 501, and the first housing 101 of the power assembly 100 is provided with a snap hole which is snap-connected with the snap buckle 501. In an example, the air inlet 105a is arranged on the front side wall and / or the rear side wall of the first housing 101 and close to the top of the first housing 101. When the cover 500 is connected with the power assembly 100, the snap buckle 501 can be snap-connected in the air inlet 105a, that is, the air inlet 105a is used as a snap hole. In this way, the snap connection of the cover 500 with the power assembly 100 is achieved, and the air inlet 105a is blocked when the cover 500 is connected with the power assembly 100, thereby reducing the risk of accidental start.

[0105] In an example, the first housing 101 is provided with a step 101a close to the top of the first housing 101. When the cover 500 is connected with the power assembly 100, the end surface of the lower end of the cover 500 abuts against the step 101a. The air inlet 105a is located between the step 101a and the top of the first housing 101, so that in use, the probability of the user's fingers blocking the air inlet 105a can be reduced.

[0106] In an example, when the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, the air inlet 202d of the first atomization assembly 200 is aligned and communicated with the first air outlet 102b in the first accommodating cavity 102, and the air inlet of the second atomization assembly 300 is aligned and communicated with the second air outlet 103b in the second accommodating cavity 103. That is, the airflow channel of the power assembly 100 is communicated with the airflow channels of the first atomization assembly 200 and the second atomization assembly 300.

[0107] In this way, when the nasal inhalation electronic atomization device 10 is inhaled, external air can flow into the first airflow cavity 105 through the air inlet 105a, then change direction and flow along the length direction of the nasal inhalation electronic atomization device 10 towards the electronic cavity 104, then change direction again and flow into the second airflow cavity 106 after passing through the air passage 107, and then flow along the width direction of the nasal inhalation electronic atomization device 10 to both sides, that is, flow out from the first air outlet 102b or the second air outlet 103b.

[0108] The air flowing out from the first air outlet 102b flows into the first atomization assembly 200 from the air inlet 202d of the first atomization assembly 200, mixes with the aerosol generated by the heating element 206, and then flows out from the aerosol outlet 201a of the first atomization assembly 200 through the transmission pipe 201d, and finally flows into one of the user's nostrils from the nasal inhalation air inlet of the first nasal inhalation piece 401, then flows out from the nasal inhalation air outlet of the first nasal inhalation piece 401 through the nasal inhalation air passage of the first nasal inhalation piece 401, and then flows into the user's nostril, thereby being inhaled.

[0109] Similarly, the air flowing out of the second air outlet 103b flows into the second atomization assembly 300 from the air inlet of the second atomization assembly 300, mixes with the aerosol generated by the heating element of the second atomization assembly 300, and then flows out of the second atomization assembly 300 from the air outlet of the second atomization assembly 300 through the transmission pipe of the second atomization assembly 300, and finally flows into the other nostril of the user from the nasal suction air inlet of the second nasal suction piece 402, and then flows out of the second nasal suction piece 402 from the nasal suction air outlet of the second nasal suction piece 402 through the nasal suction air outlet of the second nasal suction piece 402. The flow direction of the above air flow can be referred to as the dashed arrow S1 shown in the figure.

[0110] As can be seen from the figure, the air flow channel in the first atomization assembly 200 and the air flow channel in the second atomization assembly 300 extend linearly and substantially in parallel, thereby providing aerosol to the nostrils of the user through the nasal suction ports of the first nasal suction piece 401 and the second nasal suction piece 402 in parallel. Compared with the traditional bifurcated flow path, the generation of turbulence in the air flow path and the adsorption loss of the functional components of the aerosol are reduced, and the absorption rate of the functional components of the aerosol is improved.

[0111] Since the air flow channel in the first atomization assembly 200 and the air flow channel in the second atomization assembly 300 extend linearly and substantially in parallel, the first accommodating cavity 102 and the second accommodating cavity 103 are also arranged substantially in parallel and spaced apart.

[0112] The distance between the center of the first accommodating cavity 102 and the center of the second accommodating cavity 103 is the same as the above-mentioned distance d, which is generally between 15mm and 25mm, or between 15mm and 24mm, or between 15mm and 23mm, or between 15mm and 22mm, or between 16mm and 22mm, or between 17mm and 22mm, or between 18mm and 22mm, or between 19mm and 22mm.

[0113] In an example, when the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, a seal can be used to seal between the air inlet 202d of the first atomization assembly 200 and the first air outlet 102b in the first accommodating cavity 102, and a seal can also be used to seal between the air inlet of the second atomization assembly 300 and the second air outlet 103b in the second accommodating cavity 103.

[0114] In an example, when the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, the first atomization assembly 200 and the second atomization assembly 300 are arranged in sequence along the width direction of the nasal suction type electronic atomization device 10.

[0115] In an example, when the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, the third electrode assembly of the first atomization assembly 200 keeps in contact with the first electrode assembly 102a to form an electrical connection, and the third electrode assembly of the second atomization assembly 300 keeps in contact with the second electrode assembly 103a to form an electrical connection.

[0116] Specifically, the first electrode post 203 of the first atomization assembly 200 keeps in contact with the positive electrode connector in the first accommodating cavity 102 to form an electrical connection, the second electrode post 204 of the first atomization assembly 200 keeps in contact with the negative electrode connector in the first accommodating cavity 102 to form an electrical connection, the first electrode post of the second atomization assembly 300 keeps in contact with the positive electrode connector in the second accommodating cavity 103 to form an electrical connection, and the second electrode post of the second atomization assembly 300 keeps in contact with the negative electrode connector in the second accommodating cavity 103 to form an electrical connection.

[0117] In this way, when the control unit controls the power supply of the battery 1041 to the first atomization assembly 200, the current can flow to the first electrode post 203 and the second electrode post 204 of the first atomization assembly 200 through the first electrode assembly 102a in the first accommodating cavity 102, and then flow to the heating element of the first atomization assembly 200; when the control unit controls the power supply of the battery 1041 to the second atomization assembly 300, the current can flow to the first electrode and the second electrode of the second atomization assembly 300 through the second electrode assembly 103a in the second accommodating cavity 103, and then flow to the heating element of the second atomization assembly 300.

[0118] The control unit can control the battery 1041 to supply power to the first atomization assembly 200 and the second atomization assembly 300 at the same time based on the puffing signal fed back by the airflow sensor 1043, so that the first atomization assembly 200 and the second atomization assembly 300 both generate aerosol.

[0119] It can be understood that in other examples, the control unit can also control the battery 1041 to supply power to the first atomization assembly 200 and the second atomization assembly 300 at different times based on the puffing signal fed back by the airflow sensor 1043, or only control the battery 1041 to supply power to the first atomization assembly 200, or only control the battery 1041 to supply power to the second atomization assembly 300, so that the user can inhale single aerosol.

[0120] In an example, the cavity wall of the first accommodating cavity 102 is provided with a first magnetic member 102c, the cavity wall of the second accommodating cavity 103 is provided with a second magnetic member 103c, and the third electrode assembly of the first atomization assembly 200 and the second atomization assembly 300 comprises a magnetic electrode assembly.

[0121] When the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, the third electrode assembly of the first atomization assembly 200 is adsorbed with the first magnetic member 102c, and the third electrode assembly of the second atomization assembly 300 is adsorbed with the second magnetic member 103c.

[0122] In this way, on the one hand, the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, and on the other hand, the first atomization assembly 200 can be kept in the first accommodating cavity 102 and the second atomization assembly 300 can be kept in the second accommodating cavity 103.

[0123] In an example, the first shell 101 is provided with a visual window 101b, and when the first atomization assembly 200 is received in the first accommodating cavity 102 and the second atomization assembly 300 is received in the second accommodating cavity 103, the amount of liquid substrate stored in the liquid storage cavity of the first atomization assembly 200 or the second atomization assembly 300 can be observed through the visual window 101b.

[0124] For example, the shell of the first atomization assembly 200 or the second atomization assembly 300 can be made of transparent material, and the visual window 101b can be a through hole on the first shell 101. In this way, the amount of liquid substrate stored in the liquid storage cavity of the first atomization assembly 200 or the second atomization assembly 300 can be observed through the through hole.

[0125] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification.
