[0002] An electronic atomization device is an electronic product that generates an aerosol for a user to inhale by heating a liquid substrate, such as a liquid substrate containing nicotine. It is found in actual use that the user can obtain a stronger stimulation by inhaling the aerosol with the nose than by inhaling the aerosol with the mouth. In addition, when a liquid substrate with medical properties is added to the electronic atomization device, the treatment effect can be greatly improved by inhaling the aerosol with the nose.

[0055] As Figures 1-5 The nasal inhalation type electronic atomization device 10 provided by the embodiment of the present application includes a power supply assembly 100, a first atomization assembly 200, a second atomization assembly 300, a nasal inhalation piece 400, and a cover 500. The X direction in the figure represents the width direction of the nasal inhalation type electronic atomization device 10, the Y direction represents the thickness direction of the nasal inhalation type electronic atomization device 10, and the Z direction represents the length direction of the nasal inhalation type electronic atomization device 10.

[0056] It should be understood in conjunction with Figures 6-11 The power supply assembly 100 includes a first housing 101 which is substantially cuboid-shaped, and which 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 apart 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. The first accommodating cavity 102 and the second accommodating cavity 103 each have an opening, which can be provided at the top of the first housing 101, and the opening of the first accommodating cavity 102 is spaced apart 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 provided 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 is kept in a longitudinal posture and 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.

[0061] In a preferred embodiment, the first portion of the first atomization assembly 200 is received in the first accommodating cavity 102, and the second portion of the first atomization assembly 200 is exposed outside the first housing 101, i.e., the first atomization assembly 200 partially extends outside the first housing 101; the first portion of the second atomization assembly 300 is received in the second accommodating cavity 103, and the second portion of the second atomization assembly 300 is exposed outside the first housing 101, i.e., 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 portion of the first atomization assembly 200 exposed outside the first housing 101; the same applies to the second atomization assembly 300.

[0062] The first accommodating cavity 102 is provided with a first electrode assembly 102a, at least a portion 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 connectors 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 embodiment, the positive electrode connector, the first air outlet 102b, and the negative electrode connector are all arranged on the bottom cavity wall of the first accommodating cavity 102, and are arranged in sequence along the thickness direction of the nasal inhalation type electronic atomization device 10, with the first air outlet 102b located between the positive electrode connector and the negative electrode connector. When the first atomization assembly 200 is received in the first accommodating cavity 102, the first electrode assembly 102a can achieve electrical connection between the power supply assembly 100 and the first atomization assembly 200; the first air outlet 102b can achieve 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. Similar to the above, 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 be referred 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, i.e., the electronic cavity 104 is located between the bottom of the first accommodating cavity 102 and the second accommodating cavity 103 and the first housing 101. The electronic cavity 104 is provided with a battery cell 1041, a circuit board 1042, and an airflow sensor 1043.

[0064] The battery cell 1041 is configured to provide power. The battery cell 1041 can be a primary battery cell or a rechargeable battery cell. In an example, the electronic cavity 104 is further provided with a charging interface exposed through the opening 104a of the sidewall of the electronic vaping device 10, through which the battery cell can be charged.

[0065] The circuit board 1042 is provided with a control unit configured to control the overall operation of the electronic vaping device 10. The control unit can control the operation of the battery cell 1041, the first atomization assembly 200, the second atomization assembly 300, and other components of the electronic vaping device 10.

[0066] The circuit board 1042 is horizontally arranged in the electronic cavity 104, and the battery cell 1041 is located between the circuit board 1042 and the bottom wall of the electronic vaping device 10. 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 receiving 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 receiving cavity 103.

[0067] In a preferred implementation, the airflow sensor 1043 can be a common microphone assembly. One of the sensing surfaces 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 of the sidewall of the electronic vaping device 10, so that one of the sensing surfaces 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 of the power supply assembly 100. In this way, during the process of the electronic vaping device 10 being puffed, the airflow sensor 1043 can sense the change in airflow in the airflow passage.

[0068] The first housing 101 is further provided with an airflow cavity defining an airflow passage extending from the air inlet 105a to the first air outlet 102b and / or the second air outlet 103b, i.e., providing a path for air to enter the first receiving cavity 102 and the second receiving cavity 103, respectively. The airflow cavity is configured to guide air to enter the first receiving cavity 102 or the second receiving cavity 103 in a direction opposite to the opening of the first receiving cavity 102 or the second receiving cavity 103. The airflow cavity includes 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, for example, by means of a partition, a sealing member or the like.

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

[0071] The first airflow cavity 105 is in communication with the outside atmosphere through an air inlet 105a on the side wall of the first housing 101, the first airflow cavity 105 is in communication with the second airflow cavity 106 through an air passage 107, and the second airflow cavity 106 is in communication with the first air outlet 102b and the second air outlet 103b. In this way, the outside 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 suction type electronic atomization device 10 towards the second airflow cavity 106, change direction again after passing through the air passage 107 and flow into the second airflow cavity 106, and finally flow to the left or right along the width direction of the nasal suction type electronic atomization device 10, i.e. from the first air outlet 102b or the second air outlet 103b, thereby forming an airflow passage (as shown by the dashed arrow S11 in the figure) of the power supply assembly 100. The sensing passage 1043a is provided between the electronic cavity 104 and the second airflow cavity 106, and the other sensing surface of the airflow sensor 1043 is in communication with the second airflow cavity 106 through the sensing passage 1043a, so that the airflow sensor 1043 can sense the airflow change in the airflow passage during the process of the nasal suction type electronic atomization device 10 being sucked.

[0072] The air passage 107 is arranged close to the front side wall or the rear side wall of the first housing 101, i.e. the front side wall or the rear side wall of the first housing 101 defines at least part of the boundary of the air passage 107.

[0073] The first atomization assembly 200 and the second atomization assembly 300 are both used for atomizing a liquid substrate to generate an aerosol.

[0074] In Figures 1-5In the example, the first atomization assembly 200 and the second atomization assembly 300 are configured in the same way, which facilitates the batch manufacturing of the atomization assembly, simplifies the structural design of the power assembly 100, and facilitates the assembly of the atomization assembly and the power assembly 100. It can be understood that in other examples, the first atomization assembly 200 and the second atomization assembly 300 can be distinguished by structural design, or they can adopt different configurations.

[0075] The following takes the example that the first atomization assembly 200 and the second atomization assembly 300 are configured in the same way to illustrate the specific structure of the first atomization assembly 200:

[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 to each other 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 inside of the shell of 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 into the inside of the shell of the first atomization assembly 200.

[0078] Please refer to Figure 16For better understanding, the bottom cover 202 has a cavity 202a, and the third electrode assembly is arranged on the bottom cover 202, which includes 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 supply assembly 100. Another convex column is further arranged 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 process of suction, the external air enters 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 prevent the liquid substrate flowing into the cavity 202a from flowing out of the air inlet 202d to the power supply assembly 100.

[0079] The main shell 201 and the bottom cover 202 can be connected in a detachable manner. In a preferred implementation, the main shell 201 is provided with a clamping hole 201b, and the bottom cover 202 is provided with a clamping buckle 202e matched 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 convex block 202f. When the main shell 201 and the bottom cover 202 are assembled, the notch groove 201c can be aligned with the convex block 202f, and after assembly, the convex block 202f is clamped in the notch groove 201c. Through the notch groove 201c and the convex block 202f, the positioning function 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 housing 201 further has an axially extending transmission tube 201d, and a space between an outer surface of the transmission tube 201d and an inner surface of the main housing 201 forms a liquid storage chamber A for storing the liquid substrate. A hollow portion in the transmission tube 201d forms a partial airflow passage or at least a partial aerosol passage, and one end of the transmission tube 201d is in communication 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 implementation, the transmission tube 201d is integrally molded with the main housing 201 using a moldable material, and the liquid storage chamber A formed after the manufacturing is open or has an opening at a 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 the 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 substantially in a tubular structure. It can be understood that in other examples, it can also be in a plate-like structure or other regular or irregular shapes. The second liquid guide element 205 can be made of a 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 side 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 transmit heat to the liquid substrate in contact with the heating element 206 to heat the liquid substrate, thereby generating the 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 having a suitable resistance temperature coefficient characteristic, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In an example, the heating element 206 can be wound from a sheet-like or net-like base material, and the wound heating element 206 is in a non-closed tubular structure in a circumferential direction, i.e., a tubular structure having a side opening extending in a length direction or an 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, so as 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 atomizing 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 matrix in the liquid storage cavity A can be sucked by the first liquid guide element 210 to flow into the atomizing 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 matrix is prevented from being excessively or rapidly delivered to the heating element 206 by the second liquid guide element 205 sucking the liquid matrix from the first liquid guide element 210.

[0087] In an example, the first liquid guide element 210 can be made of an organic porous material with elasticity, which presents moderate flexibility and rigidity. In implementation, the first liquid guide element 210 has an elastic modulus or rigidity smaller than that of the material of the bracket 211 and larger than that of the material of the second liquid guide element 205. Specifically, it is hard cotton with a Shore hardness of 20-70A. In an alternative implementation, the first liquid guide element 210 is hard cotton including oriented polyester fibers, or hard cotton or artificial foam made of filamentous polyurethane, 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 guide element 205 extends into the notch groove 209b and is thus exposed in the liquid storage cavity A. After assembly, the first liquid guide element 210 is in contact with part of the protruding portion 205a, thereby facilitating the second liquid guide element 205 to absorb the liquid substrate.

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

[0090] The support 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 support 211 is provided with a clamping buckle 211a which is snap-fitted with the clamping hole 202g.

[0091] The bottom of the support 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 support 211 can be supported on the support portion 202h.

[0092] The support 211 is generally in a cylindrical structure, and the outside air flows into the cavity 202a through the air inlet 202d, then flows into the support 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 support 211. Specifically, the inner surface of the support 211 has a boss 211b, for example, extending radially inwardly from the inner surface of the support 211. The upper end of the connecting pipe 209 is connected to 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 further has a support portion 211c extending axially towards the direction of the aerosol outlet 201a, and 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 support portion 211c.

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

[0095] Please understand Figure 20For better understanding, the sealing member 212 can be made of flexible material, such as silica gel. 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 support 211 is at least partially accommodated in the sealing member 212, and in a preferred embodiment, the support 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 support 211, thereby achieving sealing.

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

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

[0098] In order to achieve air pressure balance between the storage cavity A and the outside, for example, when the air pressure in the storage cavity A is low due to consumption of the liquid matrix, external air can be supplemented to the storage cavity A, thereby achieving air pressure balance between the storage cavity A and the outside. In a specific embodiment, the inner surface of the support 211 is further provided with a ventilation groove 212e, one end of the ventilation groove 212e communicates with a capillary groove or groove 211g on the outer surface of the support 211 through a through hole 211f, and the other end of the ventilation groove 212e extends towards or is arranged close to the storage cavity A. The capillary groove or groove 211g can communicate with the airflow channel in the housing of the first atomization assembly 200, thereby communicating with the outside of the atomizer 10; for example, the capillary groove or groove 211g extends to a position close to the cavity 202a along the circumferential and / or axial direction of the support 211, thereby communicating 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, the plurality of capillary grooves or grooves 211g communicate with each other, and one of the plurality of capillary grooves or grooves 211g close to the cavity 202a communicates with the cavity 202a. In this way, when the air pressure in the storage cavity A is low due to consumption of the liquid matrix, external air can be supplemented to the storage cavity A through the capillary groove or groove 211g, the through hole 211f and the ventilation groove 212e, thereby achieving air pressure balance between the 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 matrix (first liquid matrix) stored in the liquid storage cavity A in the first atomization assembly 200 can be different from the liquid matrix (second liquid matrix) 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 matrix is different from the first liquid matrix in composition, or the second liquid matrix is different from the first liquid matrix in concentration. For example, in other examples, the second liquid matrix is exactly the same as the first liquid matrix in composition, and the second liquid matrix can be part of a certain liquid formula, and the first liquid matrix 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 nosepiece 400 can also be integrally formed with the first atomization assembly 200 or the second atomization assembly 300.

[0101] In an example, the first nosepiece 401 and the second nosepiece 402 each have a nosepiece port, which includes a nosepiece air inlet, a nosepiece air outlet, and a nosepiece air outlet channel 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 part 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 part 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 an arc 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 nose inhale air outlet (at the center position) of the first nose inhale piece 401 and the nose inhale air outlet (at the center position) of the second nose inhale piece 402 is the distance between two nostrils of an adult; generally, the distance d is 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. In practice, nose inhale pieces 400 of different distances d can be configured and integrally formed for users to choose; or through structural design, the distance d can be dynamically adjusted by the user, thereby facilitating the use of the user.

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

[0104] In a preferred implementation, the cover body 500 is snap connected with the power assembly 100, for example, the cover body 500 is provided with a clamping buckle 501, and the first shell 101 of the power assembly 100 is provided with a clamping hole snap-fitted with the clamping 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 shell 101 and close to the top of the first shell 101, and the clamping buckle 501 can be snap-fitted in the air inlet 105a when the cover body 500 is connected with the power assembly 100; that is, the air inlet 105a is used as a clamping hole. In this way, the snap connection of the cover body 500 and the power assembly 100 can be achieved, and the air inlet 105a can be blocked when the cover body 500 is connected with the power assembly 100, reducing the risk of accidental start.

[0105] In an example, the first shell 101 has a step 101a arranged close to the top of the first shell 101. When the cover body 500 is connected with the power assembly 100, the end face of the lower end of the cover body 500 abuts on the step 101a. The air inlet 105a is located between the step 101a and the top of the first shell 101, so that in use, the probability of the air inlet 105a being blocked by the user's fingers 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 in alignment and communication with the first air outlet 102b in the first accommodating cavity 102, and the air inlet of the second atomization assembly 300 is in alignment and communication with the second air outlet 103b in the second accommodating cavity 103. That is, the airflow channel of the power assembly 100 is in communication with the airflow channel of the first atomization assembly 200 and the airflow channel of the second atomization assembly 300.

[0107] Thus, when the nasal suction type electronic atomization device 10 is sucked, external air can flow into the first airflow cavity 105 through the air inlet 105a, then change direction to flow along the length direction of the nasal suction type electronic atomization device 10 towards the electronic cavity 104, change direction again to flow into the second airflow cavity 106 after passing through the air passage 107, and flow along the width direction of the nasal suction type electronic atomization device 10 to both sides, i.e., 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, finally flows into one of the user's nostrils from the nasal suction air inlet of the first nasal suction piece 401, flows out from the nasal suction air outlet of the first nasal suction piece 401 after passing through the nasal suction air passage of the first nasal suction piece 401, and is thus sucked.

[0109] Similarly, the air flowing out from 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 from the air outlet of the second atomization assembly 300 through the transmission pipe of the second atomization assembly 300, finally flows into the other of the user's nostrils from the nasal suction air inlet of the second nasal suction piece 402, flows out from the nasal suction air outlet of the second nasal suction piece 402 after passing through the nasal suction air passage of the second nasal suction piece 402. The flow direction of the above airflow can be referred to the dashed arrow S1 shown in the figure.

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

[0111] Since the airflow passages in the first atomization assembly 200 and the airflow passages in the second atomization assembly 300 extend linearly in a substantially parallel manner, the first accommodating cavity 102 and the second accommodating cavity 103 are also arranged in a substantially parallel manner.

[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 distance d, generally 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.

[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, the air inlet 202d of the first atomization assembly 200 and the first air outlet 102b in the first accommodating cavity 102 can be sealed by a sealing member, and the air inlet of the second atomization assembly 300 and the second air outlet 103b in the second accommodating cavity 103 can also be sealed by a sealing member.

[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 inhalation 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 maintains contact with the first electrode assembly 102a to form an electrical connection; the third electrode assembly of the second atomization assembly 300 maintains contact with the second electrode assembly 103a to form an electrical connection.

[0116] Specifically, the first electrode column 203 of the first atomization assembly 200 maintains contact with the positive electrode connecting member in the first accommodating cavity 102 to form an electrical connection, the second electrode column 204 of the first atomization assembly 200 maintains contact with the negative electrode connecting member in the first accommodating cavity 102 to form an electrical connection, the first electrode column of the second atomization assembly 300 maintains contact with the positive electrode connecting member in the second accommodating cavity 103 to form an electrical connection, and the second electrode column of the second atomization assembly 300 maintains contact with the negative electrode connecting member 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 first atomization assembly 200 by the battery 1041, the current can flow to the first electrode column 203 and the second electrode column 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 second atomization assembly 300 by the battery 1041, 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 by the first magnetic member 102c, and the third electrode assembly of the second atomization assembly 300 is adsorbed by 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, through which 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 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.

[0124] For example, the shell of the first atomization assembly 200 or the second atomization assembly 300 can be made of a 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 description of the application and its drawings, but the present application can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments are not intended to be additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Furthermore, the above technical features continue to be combined with each other to form various embodiments not listed above, which are considered to be within the scope of the present application. Furthermore, for those skilled in the art, the above description can be improved or modified, and all such improvements and modifications are intended to be within the scope of the appended claims.
