Technical Field

[0001] The embodiment of the utility model relates to the field of atomization technology, and in particular to an aerosol generating device. Background Art

[0002] The aerosol generating device is used to generate aerosol for the user to inhale.

[0003] The aerosol generating device is equipped with an air inlet channel and an atomizing core. The air inlet channel is connected to the outside of the aerosol generating device. When the user inhales the aerosol, the external airflow enters the atomizing chamber of the atomizing core through the air inlet channel, mixes with the aerosol in the atomizing chamber, and then exits the aerosol generating device.

[0004] The aerosol generating device is equipped with electronic components such as a power supply and a circuit control board. The circuit control board determines the timing of supplying power to the atomizing core based on the changes in the air pressure in the air inlet channel, and controls the voltage and current so that the atomizing core can convert an appropriate amount of aerosol generating matrix into aerosol within the appropriate time to meet the user's usage needs.

[0005] Some aerosol in the atomization chamber may not be able to exit the aerosol generating device in time, and may diffuse into the air inlet channel. In related art, the air inlet channel is connected to the space where the electronic components of the aerosol generating device are located, allowing aerosol to enter the space where the electronic components are located. This poses the risk of aerosol condensation on the electronic components, affecting their normal operation. Utility Model Content

DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present invention and should not be regarded as an improper limitation on the embodiments of the present invention.

It should be understood that these orientation terms are only used to facilitate the description of the embodiments of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present invention.

[0035] The present invention provides an aerosol generating device. Figures 1 to 4 The aerosol generating device includes an atomizing component 10 and a mounting component 30.

[0036] The atomizing assembly 10 is provided with an atomizing chamber 10a.

[0037] The mounting assembly 30 is provided with an air inlet channel 30a, which connects the atomization chamber 10a with the outside of the aerosol generating device. The air inlet channel 30a is independently provided. The mounting assembly 30 includes a mounting bracket 31 and a sealing member 32. The mounting bracket 31 is provided with a first cavity 31a. One side of the first cavity 31a is open to form a mounting opening 31d. The sealing member 32 is a sealing cover provided on the mounting opening 31d so that the first cavity 31a forms at least part of the air inlet channel 30a.

[0038] The atomizing assembly 10 is provided with an atomizing core and an aerosol generating matrix, and the atomizing cavity 10a is located in the atomizing core. The aerosol generating matrix enters the atomizing core, and the atomizing core converts the aerosol generating matrix into aerosol, which enters the atomizing cavity 10a.

[0039] It can be understood that the atomization chamber 10a is in communication with the outside of the aerosol generating device, so that the aerosol in the atomization chamber 10a can be discharged from the aerosol generating device for inhalation by the user.

[0040] When the user inhales the aerosol, negative pressure is generated in the aerosol generating device. Under the action of the negative pressure, the airflow outside the aerosol generating device enters the air inlet channel 30a, and then enters the atomizing chamber 10a to mix with the aerosol before being discharged.

[0041] It is understandable that after the user completes the inhalation, the aerosol remaining in the atomization chamber 10a can diffuse into the air inlet channel 30a and the condensate formed by the condensation of the aerosol can flow into the air inlet channel 30a.

[0042] The air inlet channel 30a is independently provided, which means that the air inlet channel 30a is not connected to other channels in the aerosol generating device, so that the fluid medium, such as aerosol, is difficult to diffuse from the air inlet channel 30a to other areas in the aerosol generating device and contact other components in the aerosol generating device.

[0043] The mounting bracket 31 and the sealing member 32 together form at least a portion of the air intake passage 30a. That is, at least a portion of the air intake passage 30a is not a one-piece structure, but rather is formed by the combination of the mounting bracket 31 and the sealing member 32. Adjusting the shapes of the mounting bracket 31 and the sealing member 32 facilitates diversifying the shape of the portion of the air intake passage 30a formed by the mounting bracket 31 and the sealing member 32. This allows, given a given total volume of the mounting assembly 30, to tailor the shape and size of the air intake passage 30a to meet airflow requirements while improving the space utilization of the mounting assembly 30 and making the structure more compact.

[0044] The aerosol generating device in the embodiment of the present invention, by independently setting up the air inlet channel 30a, makes it difficult for the aerosol and condensate entering the air inlet channel 30a to enter other areas of the aerosol generating device, and thus difficult to come into contact with other components of the aerosol generating device, which is beneficial to reducing the corrosive effect of the aerosol and condensate on other components of the aerosol generating device and is beneficial to extending the service life of the aerosol generating device; by splicing at least part of the air inlet channel 30a by the mounting bracket 31 and the sealing member 32, the arrangement of the air inlet channel 30a is beneficial to better utilize the space within the mounting bracket 31, which is beneficial to making the structure of the aerosol generating device more compact.

[0045] In some embodiments, see Figures 1 to 4 The aerosol generating device further includes an electronic device 20, which is electrically connected to the atomizer assembly 10. The electronic device 20 can provide electrical energy to the atomizer core in the atomizer assembly 10 at an appropriate time. After the atomizer core obtains the electrical energy, it converts the electrical energy by heating or other means, thereby converting an appropriate amount of aerosol-generating substrate into aerosol for the user to inhale.

[0046] The electronic device 20 refers to a device that can release, transmit and use electrical energy.

[0047] In some embodiments, the mounting assembly 30 is provided with a mounting cavity 30 b , and at least a portion of the electronic device 20 is located in the mounting cavity 30 b .

[0048] In some embodiments, see Figure 8 The mounting cavity 30b is provided on the mounting bracket 31, so as to facilitate the simultaneous preparation of the mounting cavity 30b and the first cavity 31a. The mounting cavity 30b provides a mounting position for the electronic device 20 and also enables the mounting assembly 30 to play a certain protective role for the electronic device 20.

[0049] It is understood that the air inlet channel 30a is independently provided so that the air inlet channel 30a is isolated from the mounting cavity 30b, thereby reducing the corrosive effect of aerosol and condensate on the electronic device 20, and also reducing the adverse effect of condensate on the power and signal transmission in the electronic device 20.

[0050] In some embodiments, see Figure 2 and Figure 3 The electronic device 20 includes at least one of a power supply component 21 , a circuit control board 22 and a screen component 23 .

[0051] The power supply component 21 is used to provide power to other power-consuming components in the aerosol generating device, such as the atomizer core, the screen component 23, the air pressure sensor, etc.

[0052] The power supply assembly 21 includes a battery. The specific type of the battery is not limited, such as a lithium battery, a silver-zinc battery, etc.

[0053] The circuit control board 22, which can be a PCB (Printed Circuit Board), is used to control the aerosol generating device. For example, the power supply assembly 21 is electrically connected to the atomizer core. The circuit control board 22 is electrically connected to the power supply assembly 21 to control the current and voltage provided by the power supply assembly 21 to the atomizer core, as well as the duration and on-time, so that the aerosol generated by the atomizer core meets the user's needs.

[0054] The screen assembly 23 is used to display information about the aerosol generating device, such as remaining power information, remaining aerosol generating substrate information, etc. It can also display patterns, characters and other information for users to appreciate.

[0055] It can be understood that one of the power supply component 21, the circuit control board 22 and the screen component 23 may be located in the installation cavity 30b; the power supply component 21, the circuit control board 22 and the screen component 23 may all be located in the installation cavity 30b; or a portion of each of the power supply component 21, the circuit control board 22 and the screen component 23 may be located in the installation cavity 30b.

[0056] It is understandable that in the process of the atomizer core heating the aerosol generating matrix to convert it into aerosol, due to factors such as impurities in the aerosol generating matrix, oil-frying noise may be generated during the heating process. The sound waves of the oil-frying noise can be transmitted out of the aerosol generating device along the air inlet channel 30a, creating an adverse impression on the user's experience.

[0057] In some embodiments, see Figure 4 and Figure 5 The installation component 30 also includes a partition 311, which divides the air inlet channel 30a to form a plurality of sub-cavities 30c. The installation component 30 is also provided with an air hole 30f, which connects the sub-cavities 30c on both sides of the partition 311 so that the sub-cavities 30c are connected in sequence along the flow direction of the airflow.

[0058] When the user inhales the aerosol, the airflow passes through the air holes 30f in sequence to pass between the sub-cavities 30c until it flows out of the air inlet channel 30a and enters the atomization chamber 10a.

[0059] It can be understood that, in the projection plane perpendicular to the air flow direction, the projection of the air hole 30 f is smaller than the projection of either of the two sub-cavities 30 c it communicates with.

[0060] In this way, after the sound waves of the oil-frying noise are transmitted from the atomizing chamber 10a to the air inlet channel 30a, they need to be reflected multiple times in the sub-chamber 30c before passing through the air hole 30f to enter the other sub-chamber 30c located upstream along the air flow direction, thereby increasing the propagation path and the number of reflections of the sound waves of the oil-frying noise, consuming more energy of the sound waves of the oil-frying noise, reducing the size of the oil-frying noise transmitted from the aerosol generating device, and helping to improve user experience.

[0061] The multiple sub-cavities 30c means that the number of the sub-cavities 30c is not less than two.

[0062] In some embodiments, see Figure 2 、 Figure 5 and Figure 6 One side of the first cavity 31a along the first direction is opened to form a mounting opening 31d. A partition 311 is provided in the first cavity 31a. The partition 311 extends along the first direction and connects to the inner wall of the first cavity 31a.

[0063] The mounting bracket 31 is made of engineering plastics. In the process of manufacturing the mounting bracket 31 by injection molding, after the liquid plastic solidifies, the injection mold needs to be pulled out.

[0064] After the injection mold is pulled out in the first direction, the first cavity 31 a is formed and the partition 311 is formed simultaneously. This is beneficial to simplifying the manufacturing process steps of the mounting bracket 31 and improving the manufacturing efficiency.

[0065] The seal 32 is made of an elastic material, such as silicone. The seal 32 seals the mounting opening 31d and elastically deforms, thereby reducing the chance of airflow and aerosol leaking through the joint between the seal 32 and the mounting bracket 31. This helps maintain the airtightness of the air inlet passage 30a, thereby generating negative pressure during inhalation.

[0066] In some embodiments, see Figure 4 and Figure 5 At least a portion of the partition plate 311 is spaced apart from the sealing member 32 to form the air hole 30f.

[0067] In this way, there is no need for an additional process to drill and form the air holes 30f on the partition 311. The air holes 30f can be directly formed during the demolding process by setting a corresponding structure on the injection mold, thereby improving manufacturing efficiency.

[0068] It can be understood that in an embodiment where there are multiple air holes 30 f , at least some of the air holes 30 f are formed by the sealing member 32 and the partition plate 311 .

[0069] There is no limitation on the specific method for achieving the spacing between the partition 311 and the sealing member 32 .

[0070] For example, see Figure 6 At least part of the partition 311 is provided with a notch 311a, the notch 311a passes through the partition 311 perpendicular to the first direction, and the notch 311a is open along the first direction toward one side of the installation port 31d, and the sealing member 32 and the inner wall of the notch 311a are surrounded to form an air hole 30f.

[0071] In some embodiments, see Figure 5 A portion of the end surface of the partition 311 along the first direction close to the installation port 31d is fitted with the seal 32, so that during the installation of the seal 32, the partition 311 is used to limit the seal 32 along the first direction.

[0072] In some embodiments, see Figure 5 and Figure 6 A stop rib 312 is provided in the first cavity 31a. The stop rib 312 extends along the first direction and fits with the seal 32 along the first direction, thereby facilitating the sealing member 32 to be limited along the first direction during the installation process of the sealing member 32.

[0073] In some embodiments, see Figure 8 The aerosol generating device further includes an air pressure sensor. The mounting assembly 30 is provided with a negative pressure channel 30g. The sensing area of ​​the air pressure sensor is located in the negative pressure channel 30g. The air inlet channel 30a is connected to the negative pressure channel 30g.

[0074] During the user's inhalation process, negative pressure is formed in the air inlet channel 30a. Since the air inlet channel 30a is connected to the negative pressure channel 30g, negative pressure is formed in the negative pressure channel 30g. The sensing area of ​​the air pressure sensor senses the air pressure change information in the negative pressure channel 30g and transmits the information to the circuit control board 22. The circuit control board 22 controls the power supply component 21 to supply power to the atomizer core.

[0075] In some embodiments with negative pressure channel 30g, see Figure 4 and Figure 5The sub-cavity 30c includes a negative pressure chamber 30d and a flow chamber 30e. The negative pressure channel 30g is connected to the negative pressure chamber 30d. The sensing area of ​​the air pressure sensor is located in the negative pressure channel 30g. Along the flow direction of the airflow, at least one flow chamber 30e is provided upstream of the negative pressure chamber 30d.

[0076] It can be understood that in order to generate negative pressure in the negative pressure chamber 30d in a timely manner to improve the response speed of the aerosol generating device, the size of the flow hole connecting the upstream flow chamber 30e of the negative pressure chamber 30d and the negative pressure chamber 30d is relatively small. Therefore, the air flow velocity passing through the flow hole is relatively large, which is easy to generate air flow noise and affect the user experience.

[0077] Therefore, at least one flow cavity 30e is provided upstream of the negative pressure cavity 30d, so that the sound waves of the generated airflow noise must pass through at least one flow cavity 30e before being transmitted out of the aerosol generating device, thereby increasing the propagation path and number of reflections of the sound waves of the airflow noise, consuming more energy of the sound waves of the airflow noise, and reducing the size of the airflow noise transmitted out of the aerosol generating device, which is beneficial to improving user experience.

[0078] In some embodiments, see Figure 5 Along the flow direction of the airflow, the last sub-cavity 30c forms a negative pressure cavity 30d, which is beneficial to further increase the propagation path and reflection times of the sound waves of the airflow noise, consume more energy of the sound waves of the airflow noise, reduce the size of the airflow noise transmitted from the aerosol generating device, and improve the user experience.

[0079] It is understandable that since the seal 32 is made of elastic material, the negative pressure formed in the air inlet channel 30a during the user's inhalation process will cause the seal 32 to deform, thereby affecting the speed of change of the air pressure in the air inlet channel 30a formed by the seal 32.

[0080] In some embodiments, see Figure 6 and Figure 7 The mounting bracket 31 is provided with a second cavity 31b and a throttle hole 31c. The second cavity 31b is open on one side along the second direction to form an outlet of the air intake channel 30a. The first direction intersects with the second direction. The throttle hole 31c connects the first cavity 31a and the second cavity 31b. The second cavity 31b forms a negative pressure chamber 30d, and the first cavity 31a forms at least a partial flow chamber 30e.

[0081] The throttle hole 31c forms an air passage hole 30f.

[0082] After demolding, the negative pressure chamber 30d is formed directly by forming the second cavity 31b. That is, the negative pressure chamber 30d is formed solely by the structure of the mounting bracket 31, without being surrounded by the seal 32. The structure forming the negative pressure chamber 30d is stronger and less likely to deform under negative pressure. Therefore, the volume of the negative pressure chamber 30d is less likely to decrease under negative pressure, and the air pressure inside it drops more quickly, making it easier to trigger the air pressure sensor. This improves the response speed of the aerosol generating device in generating aerosol, which is beneficial for improving the user experience.

[0083] In some embodiments where the mounting cavity 30b is provided on the mounting bracket 31, see Figure 8 The mounting cavity 30b passes through the mounting bracket 31 along the first direction. On the one hand, it is convenient to simultaneously prepare the mounting cavity 30b and the first cavity 31a by drafting along the first direction; on the other hand, it is also convenient to install the electronic device 20 into the mounting cavity 30b.

[0084] In some embodiments, see Figure 9 and Figure 10 The aerosol generating device further includes a housing 40 , which is provided with an installation space 40 a , and the atomizing assembly 10 and the installation assembly 30 are both provided in the installation space 40 a .

[0085] The housing 40 provides protection to the atomizer assembly 10 , the electronic device 20 and the mounting assembly 30 . The housing 40 can be shaped in various ways to facilitate viewing and holding by the user.

[0086] It can be understood that the atomizing assembly 10 and the mounting assembly 30 are both spaced apart from at least part of the inner wall of the mounting space 40a to form a gap, and a portion of the electronic device 20 is located in the gap, so that the structure of the aerosol generating device is more compact.

[0087] In some embodiments having a housing 40, see Figure 5 and Figure 10 The shell 40 is provided with an air inlet hole 40b, which connects the outside of the shell 40 and the installation space 40a. The seal 32 is provided with a penetrating air flow hole 32a, which connects to the first cavity 31a. The seal 32 is sealed and fitted with the inner wall of the installation space 40a, and the air flow hole 32a is connected to the air inlet hole 40b.

[0088] In this way, on the one hand, the risk of aerosol entering the installation space 40a and then condensing on the electronic device 20 is reduced; on the other hand, it is helpful to reduce the probability of gas in the installation space 40a entering the air inlet channel 30a during the user's inhalation.

[0089] In some embodiments, see Figure 4 and Figure 10One of the atomizing assembly 10 and the mounting assembly 30 is provided with a first sealing protrusion 12, and the other is provided with a limiting member 313. Both the first sealing protrusion 12 and the limiting member 313 are annular structures and one of them is embedded in the inner side of the other. The first sealing protrusion 12 and the limiting member 313 are sealed and fitted perpendicular to the embedding direction of the two, and the one located on the inner side of the two is surrounded to form a connecting space 30h, and the connecting space 30h connects the atomizing chamber 10a and the air inlet channel 30a.

[0090] It can be understood that if the first sealing protrusion 12 is embedded in the inner side of the limiting member 313, the inner side wall of the first sealing protrusion 12 is enclosed to form a connecting space 30h; if the limiting member 313 is embedded in the inner side of the first sealing protrusion 12, the inner side wall of the limiting member 313 is enclosed to form a connecting space 30h.

[0091] In this way, through the sealing fit between the first sealing protrusion 12 and the limiter 313, the probability of aerosol and condensate entering other parts of the aerosol generating device or adhering to the user from the connecting position between the atomizing chamber 10a and the air inlet channel 30a is reduced; it is also beneficial to reduce the probability of external gas entering the connecting space, which is beneficial to the formation of negative pressure in the air inlet channel 30a.

[0092] The first sealing protrusion 12 can be made of an elastic material, such as rubber, silicone, etc., and the elastic deformation of the first sealing protrusion 12 maintains a sealed fit between the first sealing protrusion 12 and the limiting member 313 .

[0093] In some embodiments, see Figure 6 The limiting member 313 is provided on the mounting bracket 31 so as to improve production efficiency by one-time injection molding.

[0094] In some embodiments, see Figure 4 The atomizer assembly 10 is located on one side of the mounting assembly 30 along the third direction. The first sealing protrusion 12 is located on the surface of the atomizer assembly 10 on the side closer to the mounting assembly 30 along the third direction. The stopper 313 is located on the surface of the mounting assembly 30 on the side closer to the atomizer assembly 10 along the third direction. The atomizer assembly 10 includes an airflow channel 10b extending along the third direction, and the atomizer chamber 10a forms at least a portion of the airflow channel 10b. This allows the communicating space 30h to communicate with the airflow channel 10b along the third direction, which helps reduce draw resistance.

[0095] In some embodiments, see Figure 10The aerosol generating device also includes a mouthpiece 60, which is provided with a through air outlet channel 60a. The atomizing assembly 10 includes a through air flow channel 10b. The atomizing chamber 10a forms at least a portion of the air flow channel 10b. The mouthpiece 60 is sealed and fitted to the atomizing assembly 10 so that the air outlet channel 60a is connected to the air flow channel 10b. The air flow channel 10b is connected to the air inlet channel 30a. The air outlet channel 60a is connected to the outside of the aerosol generating device.

[0096] The mouthpiece 60 is used by a user to hold the mouthpiece 60 in his or her mouth when using the aerosol generating device to inhale the aerosol in the airflow channel 10b.

[0097] The mouthpiece 60 is sealed against the atomizer assembly 10, so that the airflow channel 10b and the air outlet channel 60a form independent airflow paths. This makes it difficult for the airflow in the airflow channel 10b to enter other parts of the aerosol generating device or to flow out of the aerosol generating device through other airflow paths, except for flowing to the air outlet channel 60a. On the one hand, this reduces the adverse effect of air entering the airflow channel 10b and the air outlet channel 60a through the junction of the mouthpiece 60 and the atomizer assembly 10 during the user's aerosol inhalation process, thereby forming a negative pressure. On the other hand, it also reduces the probability of aerosol and condensate leaking from the junction of the mouthpiece 60 and the atomizer assembly 10 and entering other parts of the aerosol generating device or adhering to the user.

[0098] In some embodiments having a housing 40, see Figure 10 The shell 40 is provided with a mounting through hole, which connects the outside of the shell 40 and the mounting space 40a. A portion of the suction nozzle 60 is passed through the mounting through hole, and the fitting position of the suction nozzle 60 and the atomizer assembly 10 is located in the mounting space 40a.

[0099] In this way, the protective effect of the housing 40 reduces the probability of failure of the sealing between the mouthpiece 60 and the atomizer assembly 10 due to collision with external objects or the like.

[0100] In some embodiments, see Figure 3 、 Figure 4 and Figure 10 The air outlet channel 60a and the air flow channel 10b both extend along the third direction. A second sealing protrusion 11 is provided at one end of the atomizer assembly 10 along the third direction. The second sealing protrusion 11 is an annular structure. The suction nozzle 60 is embedded in the inner side of the second sealing protrusion 11 along the third direction and abuts against the mounting assembly 30 along the third direction. The circumferential side surface of the suction nozzle 60 perpendicular to the third direction is sealed with the inner surface of the second sealing protrusion 11.

[0101] During assembly of the aerosol generating device, the mouthpiece 60 is inserted into and abutted against the inner side of the second sealing protrusion 11 along the third direction, thereby establishing communication between the air outlet channel 60a and the airflow channel 10b and sealing the connection between them. The second sealing protrusion 11 serves to position, guide, and seal the device during assembly.

[0102] The second sealing protrusion 11 can be made of elastic material, such as rubber, silicone, etc., and the second sealing protrusion 11 maintains a sealed fit with the suction nozzle 60 through elastic deformation. Figure 4 and Figure 10 The aerosol generating device further includes a liquid absorbing member 50, which is disposed in the communicating space 30h.

[0103] After the condensed liquid formed by the aerosol enters the communicating space 30h, it may come into contact with the liquid absorbing member 50 and be absorbed by the liquid absorbing member 50, thereby reducing the risk of the condensed liquid entering the air inlet channel 30a and generating abnormal noise or flowing out of the aerosol generating device.

[0104] The absorbent element 50 may be formed in any form, such as cotton wool, sponge, or a fiber structure woven or twisted from chemical fibers such as polyester and nylon. In embodiments in which the second cavity 31b is provided, the opening of the second cavity 31b, located along the second direction away from the throttle orifice 31c, communicates with the communication space 30h.

[0105] In some embodiments, see Figure 7 and Figure 8 The mounting assembly 30 is provided with a through-hole 30i, which connects the connecting space 30h and the mounting cavity 30b. The atomization assembly 10 includes a conductive column, which passes through the through-hole 30i and enters the mounting cavity 30b to be electrically connected to the electronic device 20. The through-hole 30i is filled with a seal, and the conductive column is passed through the seal.

[0106] In this way, the purpose of electrically connecting the electronic device 20 to the atomizer assembly 10 is achieved. After the electrical connection between the atomizer assembly 10 and the electronic device 20 is completed during the assembly process, the purpose of isolating the connecting space 30h from the installation cavity 30b is achieved by filling the seal.

[0107] The specific type of the sealing member is not limited. For example, a sealant is filled into the through hole 30i, and the sealant is solidified to form a sealing member.

[0108] The various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.

For those skilled in the art, the embodiment of the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the embodiment of the present invention shall be included in the scope of protection of the embodiment of the present invention.
