Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to a nasal inhalation electronic atomization device. Background Technology

[0002] An electronic nebulizer is an electronic device that generates an aerosol by heating a liquid matrix, such as one containing nicotine, for the user to inhale. In practical use, it has been found that inhaling the aerosol through the nose provides a stronger stimulating sensation compared to inhaling it through the mouth. Furthermore, when a medical-grade liquid matrix is ​​added to the electronic nebulizer, nasal inhalation of the aerosol can significantly enhance the therapeutic effect.

[0003] Existing nasal inhaler e-cigarettes, limited by various factors such as cost and regulations, generally have a relatively small amount of liquid matrix stored inside the atomizer. Once the liquid matrix is ​​depleted, it must be discarded. This not only inconveniences users and reduces their user experience, but also increases their operating costs. Summary of the Invention

[0004] This application provides a nasal inhalation electronic atomizing device, which aims to solve the problems of inconvenience and increased user costs associated with existing nasal inhalation electronic atomizing devices.

[0005] This application provides a nasal inhalation electronic atomizing device, including a power supply component, a first atomizing component, and a second atomizing component;

[0006] The power supply assembly includes a first housing, inside which a battery cell for providing power is disposed, and a first receiving cavity and a second receiving cavity are formed on the first housing;

[0007] Both the first atomizing component and the second atomizing component are configured to atomize a liquid matrix to generate an aerosol. The first atomizing component is removably received in the first receiving cavity and partially extends outside the first housing. The second atomizing component is removably received in the second receiving cavity and partially extends outside the first housing.

[0008] A first aerosol outlet is provided on the portion of the first atomizing component extending outside the first housing, and a second aerosol outlet is provided on the portion of the second atomizing component extending outside the first housing. The first aerosol outlet and the second aerosol outlet output aerosol in parallel to provide it to the user's nasal cavity.

[0009] In one example, the nasal inhalation electronic atomizing device further includes a nasal inhaler for use with a user's nasal cavity. The nasal inhaler is disposed on the first atomizing component and / or the second atomizing component. The nasal inhaler has a nasal inlet that is connected to the first aerosol outlet and the second aerosol outlet, thereby delivering the aerosol generated by the first atomizing component and the second atomizing component to the user's nasal cavity.

[0010] In one example, the nasal suction device includes an arcuate or spherical surface that matches the shape of the user's nasal cavity.

[0011] In one example, the first atomizing component has a first aerosol channel communicating with the first aerosol outlet, and the second atomizing component has a second aerosol channel communicating with the second aerosol outlet. The first aerosol channel and the second aerosol channel extend in a straight line that is substantially parallel to each other, thereby providing aerosol to the user's nasal cavity in parallel.

[0012] In one example, the top or side wall of the first housing is provided with a first opening communicating with the first receiving cavity or a second opening communicating with the second receiving cavity. The first atomizing component is removably received into the first receiving cavity through the first opening, and the second atomizing component is removably received into the second receiving cavity through the second opening.

[0013] In one example, the first housing contains a first electrode assembly and a second electrode assembly electrically connected to the battery cell, with at least a portion of the first electrode assembly exposed on the cavity wall of the first receiving cavity, and at least a portion of the second electrode assembly exposed on the cavity wall of the second receiving cavity.

[0014] Both the first atomizing component and the second atomizing component include a second housing and a third electrode assembly. The second housing contains an atomizing core for atomizing a liquid matrix. The third electrode assembly is electrically connected to the atomizing core and is at least partially exposed on the outer surface of the second housing.

[0015] When the first atomizing component is received into the first receiving cavity, the third electrode component of the first atomizing component remains in contact with the first electrode component to form an electrical connection;

[0016] When the second atomizing component is received into the second receiving cavity, the third electrode component of the second atomizing component remains in contact with the second electrode component to form an electrical connection.

[0017] In one example, a first magnetic element is provided on the wall of the first receiving cavity, a second magnetic element is provided on the wall of the second receiving cavity, and the third electrode assembly of the first atomizing assembly and the second atomizing assembly includes a magnetic electrode assembly.

[0018] When the first atomizing component is received into the first receiving cavity, the third electrode component of the first atomizing component is attracted to the first magnetic component;

[0019] When the second atomizing component is received into the second receiving cavity, the third electrode component of the second atomizing component is attracted to the second magnetic component.

[0020] In one example, the first accommodating cavity has a first vent for the power supply assembly on its wall, and the second accommodating cavity has a second vent for the power supply assembly on its wall.

[0021] When the first atomizing component is received into the first receiving cavity, the air inlet of the first atomizing component is connected to the first air outlet of the power supply component;

[0022] When the second atomizing component is received into the second receiving cavity, the air inlet of the second atomizing component is connected to the second air outlet of the power supply component.

[0023] In one example, the first receiving cavity and the second receiving cavity are arranged substantially parallel to each other and spaced apart.

[0024] In one example, the first housing also has an airflow cavity located between the first receiving cavity and the second receiving cavity, the airflow cavity providing a path for air to enter the first receiving cavity and the second receiving cavity, respectively.

[0025] In one example, the distance between the center of the first receiving cavity and the center of the second receiving cavity is between 15 and 25 mm.

[0026] In one example, the device also includes a cover detachably connected to the power assembly, the cover having a snap-fit ​​fastener, and the first housing having a snap-fit ​​hole that engages with the snap-fit ​​fastener.

[0027] In one example, the snap-fit ​​hole is the air inlet of the power supply assembly.

[0028] In the above-mentioned nasal inhalation electronic atomizing device, both the first and second atomizing components can be removably installed onto the power supply component. This increases the capacity of the liquid matrix in the device and facilitates the removal or replacement of the atomizing components, thereby improving the user experience.

[0055] like Figures 1-5 This application provides a nasal inhalation electronic atomizing device 10, including a power supply assembly 100, a first atomizing assembly 200, a second atomizing assembly 300, a nasal inhalation component 400, and a cover 500. In the figure, the X direction represents the width direction of the nasal inhalation electronic atomizing device 10, the Y direction represents the thickness direction of the nasal inhalation electronic atomizing device 10, and the Z direction represents the length direction of the nasal inhalation electronic atomizing device 10.

[0056] Please combine Figures 6-11 To understand, the power supply assembly 100 includes a first housing 101, which is generally rectangular in shape and defines a portion of the sidewalls and bottom wall forming the nasal inhalation electronic atomizing device 10.

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

[0058] The first receiving cavity 102 and the second receiving cavity 103 are arranged side by side along the width direction of the nasal inhalation electronic atomizing device 10. Both the first receiving cavity 102 and the second receiving cavity 103 have openings, which can be located at the top of the first housing 101, with the openings of the first receiving cavity 102 and the second receiving cavity 103 spaced apart. The first atomizing component 200 is at least partially received or inserted into the first receiving cavity 102 through the opening, and the second atomizing component 300 is at least partially received or inserted into the second receiving cavity 103 through the opening. That is, both the first atomizing component 200 and the second atomizing component 300 are inserted from top to bottom into their respective receiving cavities along the length direction of the nasal inhalation electronic atomizing device 10, and the first atomizing component 200 and the second atomizing component 300 are also arranged sequentially along the width direction of the nasal inhalation electronic atomizing device 10.

[0059] In other examples, it is also feasible for the first receiving cavity 102 and the second receiving cavity 103 to be partially or completely connected.

[0060] In other examples, the opening of the first receiving cavity 102 or the second receiving 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. It is also feasible for the first atomizing component 200 or the second atomizing component 300 to maintain a longitudinal posture and be assembled into the corresponding receiving cavity from left to right or from right to left along the width direction of the nasal inhalation electronic atomizing device 10.

[0061] In a preferred embodiment, a first portion of the first atomizing component 200 is received in the first receiving cavity 102, and a second portion of the first atomizing component 200 is exposed outside the first housing 101, meaning a portion of the first atomizing component 200 extends outside the first housing 101; a first portion of the second atomizing component 300 is received in the second receiving cavity 103, and a second portion of the second atomizing component 300 is exposed outside the first housing 101, meaning a portion of the second atomizing component 300 extends outside the first housing 101. Thus, the user can extract the first atomizing component 200 from the first receiving cavity 102 using the portion of the first atomizing component 200 exposed outside the first housing 101; the same applies to the second atomizing component 300.

[0062] A first electrode assembly 102a is disposed in a first receiving cavity 102, at least a portion of which is exposed on the cavity wall of the first receiving cavity 102. It is understood that the first electrode assembly 102a includes a positive electrode connector and a negative electrode connector spaced apart. The first electrode assembly 102a can be a common POGO PIN, or other elastic or non-elastic conductive material. A first air outlet 102b is also disposed in the first receiving cavity 102. In a preferred embodiment, the positive electrode connector, the first air outlet 102b, and the negative electrode connector are all disposed on the bottom cavity wall of the first receiving cavity 102, arranged sequentially along the thickness direction of the nasal inhalation electronic atomizing device 10, with the first air outlet 102b located between the positive and negative electrode connectors. When the first atomizing component 200 is received in the first receiving cavity 102, the first electrode component 102a enables an electrical connection between the power supply component 100 and the first atomizing component 200; the first air outlet 102b enables fluid communication between the power supply component 100 and the first atomizing component 200, allowing air to flow into the first atomizing component 200. Similarly, the second receiving cavity 103 is provided with a second electrode component 103a and a second air outlet 103b; the specific structural design can be found in the description of the first electrode component 102a and the first air outlet 102b.

[0063] The electronic cavity 104 is located below the first receiving cavity 102 and the second receiving cavity 103, that is, the electronic cavity 104 is located between either the first receiving cavity 102 or the second receiving cavity 103 and the bottom of 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 used to provide power. The battery cell 1041 can be a primary battery cell or a rechargeable battery cell. In one example, a charging interface is also provided in the electronic cavity 104, which is exposed through an opening 104a in the side wall of the nasal inhalation electronic atomizing device 10, through which the battery cell can be charged.

[0065] A control unit is provided on the circuit board 1042. The control unit 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 battery cell 1041, the first atomization component 200, the second atomization component 300, etc., 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 nasal inhalation electronic atomizing device 10. The airflow sensor 1043 is disposed on the circuit board 1042 and on the surface of the circuit board 1042 facing away from the bottom wall of the nasal inhalation electronic atomizing device 10. The charging interface mentioned above can also be disposed on this 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 embodiment, the airflow sensor 1043 can be a common microphone assembly. One sensing surface of the airflow sensor 1043 is connected to the electronic cavity 104, which is connected to the outside through a through-hole 104b in the side wall of the nasal inhalation electronic atomizing device 10, thereby allowing one sensing surface of the airflow sensor 1043 to be connected to the external atmospheric pressure. The other sensing surface of the airflow sensor 1043 is connected to the airflow channel in the power supply assembly 100. In this way, during the inhalation process of the nasal inhalation electronic atomizing device 10, the airflow sensor 1043 can sense changes in airflow in the airflow channel.

[0068] The first housing 101 also includes an airflow cavity, which defines an airflow channel extending from the air inlet 105a to the first air outlet 102b and / or the second air outlet 103b, providing a path for air to enter the first receiving cavity 102 and the second receiving cavity 103 respectively. The airflow cavity guides air to enter the first receiving cavity 102 or the second receiving cavity 103 in a direction opposite to the opening orientation 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 chamber 105 or the second airflow chamber 106 is airtight with the first receiving chamber 102, the second receiving chamber 103 and the electronic chamber 104, which can be achieved, for example, through components such as partitions and seals.

[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 1-5In 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 description uses the example of the first atomizing component 200 and the second atomizing component 300 having the same structure to illustrate the specific structure of the first atomizing component 200:

[0076] like Figures 12 to 20 As shown, the first atomizing component 200 includes:

[0077] The main housing 201 is generally cylindrical. The main housing 201 has a proximal end and a distal end opposite each other along its length. The proximal end is provided with an aerosol outlet 201a for aerosol outflow, and the distal end is configured as an end for connection with the power supply assembly 100. The distal end of the main housing 201 is open, and a removable bottom cover 202 is mounted thereon. After being connected with the bottom cover 202, the main housing 201 and the bottom cover 202 together define the housing (second housing) of the first atomizing assembly 200, and the interior of the housing of the first atomizing assembly 200 is hollow and provided with necessary functional devices for storing and atomizing the liquid matrix; through the opening of the main housing 201, the necessary functional components can be installed into the interior of the housing of the first atomizing assembly 200.

[0078] Please combine Figure 16To understand the details, the bottom cover 202 has a chamber 202a, and a third electrode assembly is disposed on the bottom cover 202. The third electrode assembly includes a first electrode post 203 and a second electrode post 204. Specifically, the bottom wall of the chamber 202a has two protrusions. One of the protrusions has a through hole to form a first electrode hole 202b, and the conductive part 203a of the first electrode post 203 is at least partially housed in the first electrode hole 202b, while the connecting part 203b of the first electrode post 203 is exposed on the outer surface of the bottom cover 202. The other protrusion has another through hole to form a second electrode hole 202c, and the conductive part of the second electrode post 204 is at least partially housed in the second electrode hole 202c, while the connecting part of the second electrode post 204 is exposed on the outer surface of the bottom cover 202. Through the first electrode post 203 and the second electrode post 204, the first atomizing assembly 200 can be electrically connected to the power supply assembly 100. Between the two protruding pillars mentioned above, another protruding pillar is provided, which has another through hole to form an air inlet 202d. The housing of the first atomizing component 200 has an airflow channel extending from the air inlet 202d to the aerosol outlet 201a. Specifically, during suction, external air enters the first atomizing component 200 through the air inlet 202d, mixes with the generated aerosol, and then flows out of the first atomizing component 200 through the aerosol outlet 201a (as shown by the dashed arrow S12 in the figure). The aforementioned second protruding pillar also prevents the liquid matrix flowing into the chamber 202a from flowing directly out of the air inlet 202d to the power supply component 100.

[0079] The main shell 201 and the bottom cover 202 can be connected in a detachable manner. In a preferred embodiment, the main shell 201 is provided with a snap-fit ​​hole 201b, and the bottom cover 202 is provided with a snap-fit ​​buckle 202e that engages with the snap-fit ​​hole 201b.

[0080] The main shell 201 is provided with a notch 201c, and the bottom cover 202 is provided with a protrusion 202f. When assembling the main shell 201 and the bottom cover 202, the notch 201c can be aligned with the protrusion 202f before assembly. After assembly, the protrusion 202f is engaged in the notch 201c. The notch 201c and the protrusion 202f serve a positioning function, facilitating assembly.

[0081] The housing of the first atomizing component 200 includes a liquid storage chamber A, a second liquid guiding element 205, a heating element 206, a first lead wire 207, a second lead wire 208, a connecting pipe 209, a first liquid guiding element 210, a bracket 211, and a sealing element 212.

[0082] The main shell 201 also has an axially extending transmission tube 201d. The space between the outer surface of the transmission tube 201d and the inner surface of the main shell 201 forms a liquid storage cavity A for storing a liquid matrix. The hollow portion inside the transmission tube 201d forms a partial airflow channel or at least a partial aerosol channel. One end of the transmission tube 201d is connected to an aerosol outlet 201a, thereby transmitting the aerosol generated by the atomization of the heating element 206 to the aerosol outlet 201a. In a preferred embodiment, the transmission tube 201d and the main shell 201 are integrally molded from a moldable material, and the resulting liquid storage cavity A is open or partially open at the distal end.

[0083] The second liquid guiding element 205 and the heating element 206 constitute an atomizing core, which atomizes the liquid matrix and generates an aerosol. Specifically, the second liquid guiding element 205 can absorb the liquid matrix and transfer it to the heating element 206. The second liquid guiding element 205 is generally tubular. It is understood that in other examples, it can also be a plate-like structure or other regular or irregular shapes. The second liquid guiding element 205 can be made of a flexible fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the second liquid guiding element 205 can also be a rigid porous body, such as porous ceramics or porous glass. The outer surface of the second liquid guiding element 205 has radially outwardly extending protrusions 205a.

[0084] The heating element 206 can be heated by an electric current supply and transfers heat to the liquid matrix in contact with it to heat the liquid matrix, thereby generating an aerosol. The heating element 206 is disposed close to the inner surface of the second liquid guiding element 205, and can be attached to the inner surface of the second liquid guiding element 205, or partially or completely embedded in the second liquid guiding element 205. The heating element 206 can be a resistance heating mesh, resistance heating coil, etc. The heating element 206 can be made of a material with suitable temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 206 can be wound from a sheet or mesh substrate, and the wound heating element 206 is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with side openings extending along the length or axial direction of the first atomizing assembly 200.

[0085] The heating element 206 has a first lead 207 and a second lead 208 welded or arranged at both ends. The first lead 207 is in contact with the conductive part 203a of the first electrode post 203 to form an electrical connection, and the second lead 208 is in contact with the conductive part of the second electrode post 204 to form an electrical connection. Specifically, the first lead 207 and the second lead 208 extend from the bottom of the bracket 211 and are bent and held on the bottom of the bracket 211. The conductive parts 203a of the first electrode post 203 and the conductive parts of the second electrode post 204 abut against the bottom of the bracket 211, thereby maintaining contact with the first lead 207 and the second lead 208.

[0086] Both the second liquid guiding element 205 and the heating element 206 are housed within the connecting tube 209. A first liquid guiding element 210 is disposed on the outer surface of the connecting tube 209. Specifically, the tubular first liquid guiding element 210 is sleeved on the connecting tube 209. Preferably, the inner diameter of the first liquid guiding element 210 is slightly smaller than the outer diameter of the connecting tube 209, thereby ensuring that the first liquid guiding element 210 is tightly fitted onto the connecting tube 209. The connecting tube 209 is preferably made of a thin, rigid material, such as glass fiber or stainless steel. Preferably, the atomizing core is coaxially arranged with the connecting tube 209. The side wall of the connecting pipe 209 also has a liquid guide port 209a. The first liquid guide element 210 covers the liquid guide port 209a, and a portion of the second liquid guide element 205 is exposed in the liquid storage chamber A through the liquid guide port 209a. This allows the portion of the second liquid guide element 205 to be positioned close to or in contact with the first liquid guide element 210. The liquid matrix in the liquid storage chamber A can be drawn by the first liquid guide element 210 and flow through the liquid guide port 209a into the atomizing core, i.e., drawn by the second liquid guide element 205, and atomized by the heating element 206 to generate an inhalable aerosol. Advantageously, by drawing the liquid matrix from the first liquid guide element 210 through the second liquid guide element 205, excessive or rapid transfer of the liquid matrix to the heating element 206 can be avoided.

[0087] In one example, the first liquid-guiding element 210 may be made of an elastic organic porous material, exhibiting moderate flexibility and rigidity. In this embodiment, the first liquid-guiding element 210 has an elastic modulus or stiffness smaller than that of the material of the support 211 and larger than that of the material of the second liquid-guiding element 205. Specifically, it is a rigid synthetic cotton with a Shore hardness of 20–70 A. In an alternative embodiment, the first liquid-guiding element 210 is a rigid synthetic cotton comprising oriented polyester fibers, or a rigid synthetic cotton or synthetic foam made of filamentous polyurethane, etc.

[0088] A notch 209b is also provided on the side wall of the connecting pipe 209, extending from the lower end of the connecting pipe 209 toward the upper end. The protruding portion 205a of the second liquid guiding element 205 extends into the notch 209b, thereby exposing it in the liquid storage chamber A. After assembly, the first liquid guiding element 210 maintains contact with a portion of the protruding portion 205a, thereby facilitating the second liquid guiding element 205 to absorb the liquid matrix.

[0089] Please combine Figures 17-19 It is understood that the support 211 is preferably made of a rigid material, for example, in some examples the support 211 may be made of plastic material.

[0090] The bracket 211 and the bottom cover 202 can be connected by a snap-fit ​​connection. In a preferred embodiment, the bottom cover 202 is also provided with a snap-fit ​​hole 202g, and the bracket 211 is provided with a snap-fit ​​buckle 211a that engages with the snap-fit ​​hole 202g.

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

[0092] The support 211 is roughly cylindrical in shape. External air flows into the chamber 202a through the air inlet 202d, then into the support 211, mixes with the aerosol generated by the atomizing core, flows into the transmission tube 201d, and finally flows out from the aerosol outlet 201a.

[0093] At least a portion of the connecting tube 209 is housed within the support 211. Specifically, the inner surface of the support 211 has a boss 211b, which extends radially inward from the inner surface of the support 211. The upper end of the connecting tube 209 is connected to the transmission tube 201d, for example, the upper end of the connecting tube 209 is sleeved on the transmission tube 201d; the lower end of the connecting tube 209 is inserted into the connecting tube 209 and abuts against the boss 211b. Furthermore, the boss 211b also has a support portion 211c extending axially toward the aerosol outlet 201a, which supports the second liquid guiding element 205 when the lower end of the connecting tube 209 is inserted into the connecting tube 209.

[0094] At least a portion of the first liquid guiding element 210 is housed within the support 211. Specifically, the support 211 also has a support portion 211d, which extends axially toward the aerosol outlet 201a. The first liquid guiding element 210 is supported by the support portion 211d.

[0095] Please combine Figure 20For clarity, the seal 212 can be made of a flexible material, such as silicone. The seal 212 is cylindrical. The lower end of the seal 212 is fitted onto the bottom cover 202, and the end face of the lower end of the seal 212 abuts against the step 202i of the bottom cover 202. The bracket 211 is at least partially housed within the seal 212; in a preferred embodiment, the bracket 211 is located within the seal 212. When the main housing 201 and the bottom cover 202 are connected, a portion of the seal 212 is sandwiched between the main housing 201 and the bottom cover 202, and another portion of the seal 212 is sandwiched between the main housing 201 and the bracket 211, thereby achieving a seal.

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

[0097] Furthermore, the inner surface of the seal 212 has a step 212b. When the bracket 211 is assembled inside the seal 212, the upper end face of the bracket 211 can abut against the step 212b, thus axially limiting the bracket 211 and achieving the effect of proper assembly.

[0098] To achieve pressure balance between the liquid storage chamber A and the external environment, for example, when the pressure in the liquid storage chamber A is low due to the consumption of the liquid matrix, external air can be added to the liquid storage chamber A, thereby achieving pressure balance between the liquid storage chamber A and the external environment. In a specific implementation, the inner surface of the support 211 is also provided with a venting groove 212e. One end of the venting groove 212e is connected to the capillary groove or recess 211g on the outer surface of the support 211 through a through hole 211f, and the other end of the venting groove 212e extends toward or is located close to the liquid storage chamber A. The capillary groove or recess 211g can communicate with the airflow channel inside the housing of the first atomizing component 200, thereby communicating with the outside of the atomizer 10; for example, the capillary groove or recess 211g extends along the circumferential and / or axial direction of the support 211 to a position near the chamber 202a, thereby communicating with the chamber 202a; or, multiple capillary grooves or recesses 211g are provided on the outer surface of the support 211, the multiple capillary grooves or recesses 211g are arranged along the circumferential and / or axial direction of the support 211, the multiple capillary grooves or recesses 211g are interconnected, and one of the capillary grooves or recesses 211g near the chamber 202a communicates with the chamber 202a. In this way, when the air pressure in the liquid storage chamber A is low due to the consumption of the liquid matrix, external air can be replenished to the liquid storage chamber A through the capillary groove or recess 211g, the through hole 211f, and the venting groove 212e, thereby achieving air pressure balance between the liquid storage chamber A and the outside.

[0099] It should be noted that, based on the specific structure of the first atomizing component 200 described above, those skilled in the art can understand the second atomizing component 300 with the same structural design. It is understood that the liquid matrix (first liquid matrix) stored in the liquid storage chamber A of the first atomizing component 200 and the liquid matrix (second liquid matrix) stored in the liquid storage chamber of the second atomizing component 300 can be different or the same. For example, in some examples, the composition of the second liquid matrix is ​​different from that of the first liquid matrix, or the concentration of the second liquid matrix is ​​different from that of the first liquid matrix. For example, in other examples, the composition of the second liquid matrix is ​​exactly the same as that of the first liquid matrix; the second liquid matrix can be one part of a certain liquid formulation, while the first liquid matrix can be another part of a certain liquid formulation.

[0100] The nasal suction device 400 is made of a flexible material, such as food-grade silicone. The nasal suction device 400 includes a first nasal suction device 401 and a second nasal suction device 402. The first nasal suction device 401 and the second nasal suction device 402 can be integrally formed, for example... Figures 1-5 As shown; the first nasal suction device 401 and the second nasal suction device 402 can also be independent of each other. The nasal suction device 400 is detachably connected to the first atomizing assembly 200 or the second atomizing assembly 300, for example... Figures 1-5 As shown; the nasal inhaler 400 can also be integrally formed with the first atomizing component 200 or the second atomizing component 300.

[0101] In one example, both the first nasal inhaler 401 and the second nasal inhaler 402 have nasal inhalation ports, which include a nasal inlet, a nasal outlet, and a nasal outlet passage extending from the nasal inlet to the nasal outlet. One end of the first nasal inhaler 401 is fitted onto the first atomizing component 200, for example, onto the portion of the first atomizing component 200 exposed outside the first housing 101, and the nasal inlet of the first nasal inhaler 401 is connected to the aerosol outlet 201a of the first atomizing component 200; one end of the second nasal inhaler 402 is fitted onto the second atomizing component 300, for example, onto the portion of the second atomizing component 300 exposed outside the first housing 101, and the nasal inlet of the second nasal inhaler 402 is connected to the outlet 201 of the second atomizing component 300. The other end of the first nasal suction device 401 or the second nasal suction device 402 includes an arc surface or a spherical crown surface that matches the shape of the user's nasal cavity. The other end of the first nasal suction device 401 or the second nasal suction device 402 can be close to the user's nasal cavity, so that the nasal suction outlet of the first nasal suction device 401 or the second nasal suction device 402 is connected to the nasal cavity. That is, the nasal suction outlet of the first nasal suction device 401 transmits the aerosol generated by the first atomizing component 200 to one of the user's nasal cavities, and the nasal suction outlet of the second nasal suction device 402 transmits the aerosol generated by the second atomizing component 300 to the user's other nasal cavity.

[0102] The distance d between the nasal air outlet (center position) of the first nasal suction device 401 and the nasal air outlet (center position) of the second nasal suction device 402 is the distance between the two nasal cavities 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, nasal suction devices 400 with different distances d can be configured and integrally formed for users to choose from; alternatively, the structural design can allow users to dynamically adjust the distance d, thus facilitating user operation.

[0103] The cover 500 is detachably connected to the power supply assembly 100, and the cover 500 defines another part of the sidewall and top wall forming the nasal inhalation electronic atomizing device 10. When the cover 500 is connected to the power supply assembly 100, the first atomizing assembly 200 and the second atomizing assembly 300 are completely housed within the nasal inhalation electronic atomizing device 10.

[0104] In a preferred embodiment, the cover 500 is snap-fitted to the power assembly 100. For example, a snap-fit ​​buckle 501 is provided inside the cover 500, and a snap-fit ​​hole is provided on the first housing 101 of the power assembly 100 to engage with the snap-fit ​​buckle 501. In one example, the air inlet 105a is located on the front and / or rear sidewalls of the first housing 101 and near the top of the first housing 101. When the cover 500 is connected to the power assembly 100, the snap-fit ​​buckle 501 can snap into the air inlet 105a; that is, the air inlet 105a is used as a snap-fit ​​hole. In this way, the snap-fit ​​connection between the cover 500 and the power assembly 100 can be achieved, and the air inlet 105a can be blocked when the cover 500 is connected to the power assembly 100, reducing the risk of accidental start-up.

[0105] In one example, the first housing 101 has a step 101a located near the top of the first housing 101. When the cover 500 is connected to the power assembly 100, the lower end face 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, thus reducing the likelihood of the user's fingers blocking the air inlet 105a during use.

[0106] In one example, when the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the air inlet 202d of the first atomizing component 200 is aligned and connected with the first air outlet 102b in the first receiving cavity 102, and the air inlet of the second atomizing component 300 is aligned and connected with the second air outlet 103b in the second receiving cavity 103. That is, the airflow channel of the power supply component 100 is connected to the airflow channels of the first atomizing component 200 and the second atomizing component 300.

[0107] Thus, when the nasal inhalation electronic atomizing device 10 is drawn in, 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 electronic chamber 104. After passing through the air outlet 107, it flows in a different direction into the second airflow chamber 106, and flows to both sides 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.

[0108] Air flowing from the first air outlet 102b enters the first atomizing component 200 through the air inlet 202d. After mixing with the aerosol generated by the heating element 206, it flows out through the transmission pipe 201d from the aerosol outlet 201a of the first atomizing component 200, and finally flows in through the nasal inlet of the first nasal inhaler 401. After passing through the nasal outlet of the first nasal inhaler 401, it flows into one of the user's nasal cavities and is thus inhaled.

[0109] Similarly, air flowing from the second air outlet 103b enters the second atomizing component 300 through its air inlet, mixes with the aerosol generated by the heating element of the second atomizing component 300, flows out through the transmission tube of the second atomizing component 300, and finally flows into the nasal inlet of the second nasal inhaler 402. After passing through the nasal outlet of the second nasal inhaler 402, it flows into the user's other nasal cavity through its nasal outlet. The direction of the airflow can be seen from the dashed arrow S1 in the figure.

[0110] As shown in the figure, the airflow channels in the first atomizing component 200 and the second atomizing component 300 extend in a straight line, essentially parallel to each other, thereby providing aerosol to the user's nasal cavity in parallel through the nasal inhalations of the first nasal inhaler 401 and the second nasal inhaler 402. Compared to the traditional bi-directional airflow path, this reduces the generation of turbulence in the airflow path and the adsorption loss of aerosol functional components, thus improving the absorption rate of aerosol functional components.

[0111] Since the airflow channels in the first atomizing component 200 and the airflow channels in the second atomizing component 300 extend in a straight line that is basically parallel, the first receiving cavity 102 and the second receiving cavity 103 are also basically parallel and spaced apart.

[0112] The distance between the center of the first receiving cavity 102 and the center of the second receiving cavity 103 is the same as the aforementioned distance d, and 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 one example, when the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the air inlet 202d of the first atomizing component 200 and the first air outlet 102b in the first receiving cavity 102 can be sealed by a sealing element, and the air inlet of the second atomizing component 300 and the second air outlet 103b in the second receiving cavity 103 can also be sealed by a sealing element.

[0114] In one example, when the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the first atomizing component 200 and the second atomizing component 300 are arranged sequentially along the width direction of the nasal inhalation electronic atomizing device 10.

[0115] In one example, when the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the third electrode assembly of the first atomizing component 200 remains in contact with the first electrode assembly 102a to form an electrical connection; the third electrode assembly of the second atomizing component 300 remains in contact with the second electrode assembly 103a to form an electrical connection.

[0116] Specifically, the first electrode post 203 of the first atomizing component 200 maintains contact with the positive electrode electrical connector in the first receiving cavity 102 to form an electrical connection, the second electrode post 204 of the first atomizing component 200 maintains contact with the negative electrode electrical connector in the first receiving cavity 102 to form an electrical connection, the first electrode post of the second atomizing component 300 maintains contact with the positive electrode electrical connector in the second receiving cavity 103 to form an electrical connection, and the second electrode post of the second atomizing component 300 maintains contact with the negative electrode electrical connector in the second receiving cavity 103 to form an electrical connection.

[0117] Thus, when the control unit controls the battery cell 1041 to provide power to the first atomizing assembly 200, the current can flow through the first electrode assembly 102a in the first receiving cavity 102 to the first electrode post 203 and the second electrode post 204 of the first atomizing assembly 200, and then to the heating element of the first atomizing assembly 200; when the control unit controls the battery cell 1041 to provide power to the second atomizing assembly 300, the current can flow through the second electrode assembly 103a in the second receiving cavity 103 to the first electrode and the second electrode of the second atomizing assembly 300, and then to the heating element of the second atomizing assembly 300.

[0118] The control unit can control the battery cell 1041 to simultaneously supply power to the first atomizing component 200 and the second atomizing component 300 based on the suction signal fed back by the airflow sensor 1043, so that both the first atomizing component 200 and the second atomizing component 300 generate aerosols.

[0119] Understandably, in other examples, the control unit can also control the battery cell 1041 to provide power to the first atomizing component 200 and the second atomizing component 300 in a time-sharing manner based on the suction signal fed back by the airflow sensor 1043, or control the battery cell 1041 to provide power to the first atomizing component 200 only, or control the battery cell 1041 to provide power to the second atomizing component 300 only, so that the user can inhale a single aerosol.

[0120] In one example, a first magnetic element 102c is provided on the cavity wall of the first receiving cavity 102, a second magnetic element 103c is provided on the cavity wall of the second receiving cavity 103, and the third electrode assembly of the first atomizing assembly 200 and the second atomizing assembly 300 includes a magnetic electrode assembly.

[0121] When the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the third electrode component of the first atomizing component 200 is attracted to the first magnetic element 102c, and the third electrode component of the second atomizing component 300 is attracted to the second magnetic element 103c.

[0122] In this way, on the one hand, it is convenient for the first atomizing component 200 to be received in the first receiving cavity 102 and the second atomizing component 300 to be received in the second receiving cavity 103, and on the other hand, it is possible to keep the first atomizing component 200 in the first receiving cavity 102 and the second atomizing component 300 in the second receiving cavity 103.

[0123] In one example, a viewing window 101b is provided on the first housing 101. When the first atomizing component 200 is received in the first receiving cavity 102 and the second atomizing component 300 is received in the second receiving cavity 103, the amount of liquid matrix stored in the liquid storage cavity of the first atomizing component 200 or the second atomizing component 300 can be observed through the viewing window 101b.

[0124] For example, the housing of the first atomizing component 200 or the second atomizing component 300 can be made of a transparent material, and the viewing window 101b can be a through hole on the first housing 101. In this way, the amount of liquid matrix stored in the liquid storage chamber of the first atomizing component 200 or the second atomizing component 300 can be observed through the through hole.

[0125] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
