The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0025] In the related art, the main airway and the sensing airway of the atomizer are separated from each other and lack effective sealing means. There is still cross-flow between the main airway and the sensing airway, resulting in a poor user experience.

[0026] Please refer to Figure 1-3 In an embodiment of the present application, a nozzle assembly 1 is provided, which includes a shell and a seal 15; the shell includes an inner shell 11 and an outer shell 12, the inner shell 11 encloses a main air passage 110, and the main air passage 110 has an air outlet end 112 and an air inlet end 111 arranged oppositely along the axial direction; the outer shell 12 is arranged around the circumference of the inner shell 11, and the outer shell 12 is connected to the inner shell 11 at the air outlet end 112; a cavity 13 is formed between the inner shell 11 and the outer shell 12, and the inner shell 1 ... An air hole 14 connecting the cavity 13 with the outside is provided at the connection of the outer shell 12; a seal 15 is filled in the cavity 13; the seal 15 is provided with a first through hole 151, one end of the first through hole 151 is connected to the air hole 14 through the cavity 13, and the first through hole 151 and the cavity 13 together form a sensing airway 150, which is used to connect the pneumatic switch with the air hole 14, and the sensing airway 150 and the main airway 110 are separated from each other by the seal 15 and the inner shell 11.

[0027] The nozzle assembly 1 in the embodiment of the present application is used as a gas outlet of the atomizing device as a whole. The gas outlet is used as the gas outlet of the main airway in the atomizing device for discharging aerosol, and is used as the triggering gas outlet of the pneumatic switch in the atomizing device. When the pneumatic switch detects negative pressure, it can trigger the atomizer to heat the aerosol matrix to generate aerosol, and then discharge it along the main airway.

[0028] The main components of the nozzle assembly 1 include a shell and a seal 15. The shell includes an inner shell 11 and an outer shell 12, which are arranged inside and outside. The inner shell 11 itself is surrounded along the circumference to form a main airway 110, which is used to discharge aerosol; along the axial direction of the main airway 110, the main airway 110 has an air outlet end 112 and an air inlet end 111 which are arranged opposite to each other, wherein the air inlet end 111 is used to communicate with the atomizing device as an inlet of the aerosol discharged outward; the air outlet end 112 is connected to the outside and serves as an outlet of the aerosol discharged outward.

[0029] The outer shell 12 is arranged around the circumference of the inner shell 11, that is, the outer shell 12 is arranged outside the inner shell 11 along the circumferential direction, and the outer shell 12 and the inner shell 11 are connected at the air inlet end 111. The gap between the outer shell 12 and the inner shell 11 forms a cavity 13, and the cavity 13 can communicate with the outside through the air hole 14 arranged at the connection between the inner shell 11 and the outer shell 12. It is worth mentioning that the air hole 14 is arranged at the connection between the outer shell 12 and the inner shell 11, and the main air channel 110 formed by the circumferential enclosure of the inner shell 11 itself is not connected to the air hole 14.

[0030] The cavity 13 cooperates with the air hole 14, which is equivalent to forming the airway space required by the sensing airway 150; then, in order to improve the sealing between the sensing airway 150 and the main airway 110, the embodiment of the present application also includes a seal 15, which is directly filled in the cavity 13, so that the cavity 13 forms a closed space because of the seal 15; the seal 15 is also provided with a first through hole 151, one end of which is connected to the air hole 14 through the cavity 13, thereby forming a channel of the air hole 14-cavity 13-first through hole 151, which is used as the sensing airway 150. The sensing airway 150 is separated from the main airway 110 by the seal 15 and the inner shell 11, thereby effectively improving the sealing between the main airway 110 and the sensing airway 150, and reducing the phenomenon of cross-flow between the main airway 110 and the sensing airway 150.

[0031] In addition, in addition to being used to achieve sealing between the main airway 110 and the sensing airway 150, the seal 15 is also used to seal the nozzle assembly 1 with other parts of the atomizer when the nozzle assembly 1 is installed in the atomizer, thereby preventing leakage of the aerosol matrix in the atomizer.

[0032] In some alternative embodiments, please refer to Figure 2 and Figure 3In order to improve the sealing performance of the seal 15, the seal 15 includes an elastic seal 150. The elastic seal 150 is elastic. When the elastic seal 150 is filled in the cavity, the elastic seal 150 is in close contact with the inner wall of the cavity. At the same time, the elastic seal 150 has a tendency to expand outward due to its elasticity, thereby further enhancing the contact strength with the inner wall of the cavity, effectively improving the sealing performance. The elastic seal 150 has a second through hole 152, and at least part of the structure of the inner shell 11 is embedded in the second through hole 152. At least part of the structure of the elastic seal 150 abuts against the inner wall of the outer shell 12. The elastic seal 150 is set as an integrally formed structure, which has a simple structure and can ensure excellent sealing performance; the elastic seal 150 realizes the sealing of the inner shell 11 and the outer shell 12 through elastic deformation, wherein when the elastic seal 150 is placed in the cavity 13 between the inner shell 11 and the outer shell 12, the elastic seal 150 can abut against the inner shell 11 and the outer shell 12, and there is no gap at the contact point, thereby ensuring the sealing performance. In order to fill the elastic seal 150 in the cavity 13, a second through hole 152 is provided on the elastic seal 150, and the second through hole 152 is directly sleeved on the outer side of the inner shell 11, so that at least part of the structure of the inner shell 11 is directly embedded in the second through hole 152. In this state, the elastic seal 150 abuts against the inner shell through the second through hole 152.

[0033] The elastic sealing member 150 in the embodiment of the present application may specifically include rubber elastomer, thermoplastic elastomer, engineering plastic, composite material, etc.

[0034] In some alternative embodiments, please refer to Figure 2 and Figure 3 In order to further improve the sealing effect of the seal 15, the seal 15 also includes a sealing ring 153 disposed on the elastic seal 150, and the sealing ring 153 abuts against the inner wall of the housing 12. The sealing ring 153 surrounds the surface of the elastic seal 150 facing the housing 12, and the elastic seal 150 is further closely contacted with the inner wall of the housing 12 through the sealing ring 153. The sealing ring 153 is continuously distributed along the outer surface of the elastic seal 150. By providing the sealing ring 153, the sealing performance of the seal 15 can be improved while reducing the difficulty of assembling the seal 15, so that the seal 15 can be easily assembled into the cavity 13. In addition, the elastic seal 150 and the sealing ring 153 can be directly integrally formed, or the elastic seal 150 and the sealing ring 153 can be in a split structure. A groove matching the sealing ring 153 can be provided on the outer surface of the elastic seal 150, and the sealing ring 153 can be embedded in the groove of the elastic seal 150 during assembly, and then the entire seal 15 is filled in the cavity 13.

[0035] In some alternative embodiments, please refer to Figure 2 and Figure 3 In order to collect the condensate generated by the condensation of the aerosol, the nozzle assembly 1 may further include a liquid absorbent 16, which is arranged at the air inlet end 111 of the main airway 110; the liquid absorbent 16 is used to absorb the condensate that flows back into the main airway 110. The liquid absorbent 16 is arranged at the air inlet end 111 of the main airway 110. When the aerosol matrix is ​​heated by the atomizer, the formed aerosol will be discharged from the main airway 110, and part of the aerosol will condense to form condensate due to the cold, and the condensate will flow back through the inner wall of the inner shell 11 constituting the main airway 110; therefore, by arranging the liquid absorbent 16 at the air inlet end 111 of the main airway 110, when the condensate flows back, it will be absorbed by the liquid absorbent 16, thereby preventing the condensate from flowing back into the atomizer.

[0036] In some alternative embodiments, please refer to Figure 2 and Figure 3 In order to increase the absorption effect of the liquid absorbent 16 on the condensate, the liquid absorbent 16 is attached to the side of the sealing member 15 away from the pore 14, and the liquid absorbent 16 is provided with a third through hole 161 and a fourth through hole 162 that penetrate the liquid absorbent 16, the third through hole 161 is interconnected with the main airway 110, and the fourth through hole 162 is interconnected with the first through hole 151. In this case, the liquid absorbent 16 is in a block shape as a whole, and the liquid absorbent 16 and the sealing member 15 form a surface contact, so that the condensate can be diffused in the liquid absorbent 16, thereby increasing the amount of aerosol absorbed by the liquid absorbent 16 as much as possible. In other words, the larger the volume of the liquid absorbent 16, the better its absorption effect on the condensate. In order for the aerosol to circulate normally, a third through hole 161 is provided on the liquid absorbent 16, wherein the third through hole 161 and the main airway 110 are interconnected, so that the aerosol can pass through the third through hole 161 into the main airway 110 and then be discharged outward. In order not to affect the penetration of the sensing airway 150 , a fourth through hole 162 is provided on the liquid absorbing member 16 . The fourth through hole 162 is communicated with the first through hole 151 , that is, the fourth through hole 162 is communicated with the sensing airway 150 .

[0037] Based on the communication structure among the main air passage 110 , the second through hole 152 and the third through hole 161 , the main air passage 110 , the second through hole 152 and the third through hole 161 can be coaxially arranged, which can facilitate assembly and sealing.

[0038] In some optional embodiments, in order to increase the absorption effect of the liquid absorbent 16 on the condensed liquid, the cross-sectional area of ​​the liquid absorbent 16 along the direction perpendicular to the axis is larger than the end surface area of ​​the sealing member 15. The cross-sectional area of ​​the liquid absorbent 16 can be larger than the end surface of the sealing member 15 to enhance the liquid storage effect of the liquid absorbent 16 and enhance the absorption effect on the condensed liquid.

[0039] In some alternative embodiments, please refer to Figure 2 and Figure 3 The inner shell 11 and the outer shell 12 together form a shell. In order to ensure the connection strength, the inner shell 11 and the outer shell 12 can be directly integrated. In addition, when the inner shell 11 and the outer shell 12 are directly integrated, the manufacturing process of the inner shell 11 and the outer shell 12 can be combined into one step, thereby effectively reducing the manufacturing process of the product. Moreover, since the inner shell 11 and the outer shell 12 are integrally formed, the structure presented by the shell is a seamless integral structure with good structural strength, without the need for additional assembly process, which is conducive to improving production efficiency.

[0040] The nozzle assembly 1 provided in the embodiment of the present application realizes the mutual separation between the main airway 110 and the sensing airway 150 by setting an inner shell 11 and an outer shell 12, and a seal 15 is further set between the inner shell 11 and the outer shell 12, and the normal circulation of the sensing airway 150 is ensured by a first through hole 151 set on the seal 15, so that the sealing between the main airway 110 and the sensing airway 150 is improved by combining the seal 15 and the inner shell 12, thereby improving the user experience.

[0041] The present application also provides an atomization device, please refer to Figure 4 and Figure 5 The atomizing device includes an atomizer 4 and the above-mentioned nozzle assembly 1; wherein the atomizer 4 includes an atomizing air channel 41, and the atomizing air channel 41 is interconnected with the main air channel 110.

[0042] The atomizer 4 is used to heat the aerosol matrix to generate an aerosol, and the aerosol is discharged outward along the atomization airway 41 and the main airway 110 which are interconnected.

[0043] In addition, the atomization device in the embodiment of the present application further includes a housing assembly 2 and a pneumatic switch 3; the pneumatic switch 3 and the atomizer 4 are both arranged in the housing assembly 2, and the nozzle assembly 1 is connected to the housing assembly 2.

[0044] The housing assembly 2 is provided with an air inlet cavity 21, and the pneumatic switch 3 is arranged in the air inlet cavity 21, and the air inlet cavity 21 is connected with the sensing airway 150 on the nozzle assembly 1. When the pneumatic switch 3 senses negative pressure from the air inlet cavity 21, it drives the atomizer 4 to work, so as to heat the aerosol matrix to generate aerosol discharge.

[0045] The atomizing device in the embodiment of the present application is used to heat the aerosol matrix to generate aerosol and then discharge it; wherein, the components of the atomizing device include a housing assembly 2, a pneumatic switch 3, an atomizer 4 and a nozzle assembly 1 in the embodiment of the present application. A receiving cavity is formed inside the housing assembly 2, and the receiving cavity can be used to accommodate various components including the pneumatic switch 3 and the atomizer 4, and the arrangement positions of the pneumatic switch 3 and the atomizer 4 in the receiving cavity can be arranged according to the structure of the receiving cavity in the atomizer, which is not limited in the present embodiment.

[0046] In the embodiment of the present application, the nozzle assembly 1 is connected to the housing assembly 2, that is, the assembly between the nozzle assembly 1 and the housing assembly 2 is detachable or fixed. A main airway 110 and a sensing airway 150 are formed in the nozzle assembly 1, wherein the main airway 110 is connected to the atomizer 4, and the sensing airway 150 is connected to the pneumatic switch 3.

[0047] To create a confined space, please refer to Figure 5 An air inlet cavity 21 is formed in the housing assembly 2 , and the air inlet cavity 21 is connected to the induction airway 150 in the nozzle assembly 1 , and the pneumatic switch 3 is disposed in the air inlet cavity 21 .

[0048] In some optional embodiments, in order to improve the sealing performance of the sensing airway 150, please refer to Figure 5 The housing component 2 is also formed with a hollow air duct 22, which is in communication with the air inlet cavity 21; the air duct 22 is inserted into the first through hole 151 of the seal 15, and the air duct 22 is sealed with the seal 15 at the first through hole 151. The air duct 22 is directly inserted into the first through hole 151 of the seal 15, and the air duct 22 can be sealed together by utilizing the sealing characteristics of the seal 15, so that the space between the sensing airway 150 and the air inlet cavity 21 is more sealed. The air duct 22 formed on the housing component 2 can be directly integrally formed with the housing component 2, so that based on the structure in which the air duct 22 is inserted into the seal 15, the sealing performance of the sensing airway 150 can be further improved.

[0049] In some optional embodiments, in order to prevent the aerosol condensate from flowing back into the sensing airway 150, the nozzle assembly 1 includes a liquid absorbing member 16, which has a fourth through hole 162, and the fourth through hole 162 is connected to the first through hole 151; the air guide tube 22 passes through the fourth through hole 162 and is inserted into the first through hole 151. Since the air guide tube 22 directly passes through the fourth through hole 162 and is inserted into the first through hole 151, the condensate absorbed by the liquid absorbing member 16 will be directly isolated by the outer wall of the air guide tube 22, and combined with the air guide tube 22 being sealed with the sealing member 15 through the first through hole 151, the condensate is prevented from entering the air inlet cavity 21, ensuring that the pneumatic switch 3 can work normally.

[0050] The atomizing device in the embodiment of the present application may further include a power supply assembly 5 for supplying power to the atomizer 4. The power supply assembly 5 may be directly or indirectly electrically connected to the atomizer 4 and provide the atomizer 4 with the power required for operation, so that the atomizer 4 enters the working state to heat the aerosol matrix to generate aerosol. The power supply assembly 5 may be disposed in the housing assembly 2 and away from the location of the nozzle assembly 1, and the atomizer 4 may be disposed between the nozzle assembly 1 and the power supply assembly 5.

[0051] The power supply component 5 can be connected to the housing component 2 in a detachable manner, and the power supply component 5 can be peeled off the housing component 2 by disassembling the connection between the power supply component 5 and the housing component 2, so that the power supply component 5 can be replaced. In addition, the power supply component 5 can also be directly fixed in the accommodating cavity of the housing component 2. This structure of the atomizer device is mostly used for disposable products.

[0052] In addition, the atomizer device in the embodiment of the present application may further include a liquid replenishing component 6. The liquid replenishing component 6 is detachably connected to the housing component 2, and the liquid replenishing component 6 is used to store liquid aerosol matrix so as to replenish the aerosol matrix processed by the atomizer 4, thereby increasing the number of times / duration of use of the atomizer device.

[0053] The liquid replenishing component 6 can be arranged on the same side as the power supply component 5, that is, the arrangement positions of the liquid replenishing component 6 and the power supply component 5 are more independent relative to other mechanisms in the atomization device. This makes it convenient to design power supply components 5 of different capacities based on atomization device products of different specifications, or to design liquid replenishing components 6 of different capacities, etc., which can enrich the application scenarios of the products.
