[0034] An embodiment of the present application provides an atomization device, which includes multiple atomization bins, wherein the multiple atomization bins can share one airflow sensor to achieve an airflow sensing function, simplify the internal structure of the atomization device, save the internal space of the shell, and provide convenience for the internal space layout of the atomization device.

[0035] It should be noted that, in the embodiment of the present application, the first direction is the height direction of the atomization device, and the first direction intersects with the second direction. Preferably, the first direction is perpendicular to the second direction.

[0036] The atomization device provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0037] Reference Figure 1 , showing a schematic diagram of the structure of the atomization device according to the embodiment of the present application, referring to Figure 2 , shows a front view of the atomization device according to an embodiment of the present application, referring to Figure 3 , showing a cross-sectional view of the atomization device according to an embodiment of the present application, referring to Figure 4 , showing a side view of the atomization device according to an embodiment of the present application, referring to Figure 5 , showing a cross-sectional view of the atomization device according to an embodiment of the present application from another angle, referring to Figure 6 , showing one of the internal structure schematic diagrams of the atomization device described in the embodiment of the present application, referring to Figure 7 , which shows the second internal structure schematic diagram of the atomization device described in the embodiment of the present application.

[0038] like Figures 1 to 7 As shown, the atomization device disclosed in the present application may specifically include: a housing 10 , a bracket 20 , at least two atomization bins 30 and an airflow sensor 40 .

[0039] Reference Figure 8 , showing a schematic diagram of the structure of the bracket 20 according to the embodiment of the present application, referring to Fig. 9, showing a schematic diagram of the structure of the bracket 20 at another angle according to the embodiment of the present application, referring to Fig.10 , showing a top view of the bracket 20 of the embodiment of the present application, referring to Fig.11 , shows a bottom view of the bracket 20 described in the embodiment of the present application. Figures 8 to 11 As shown, the bracket 20 includes a first side and a second side which are arranged in opposite directions along a first direction x, and the bracket 20 is connected in the shell 10, and the first side of the bracket 20 and the shell 10 are enclosed to form a first accommodating cavity 101, and the second side of the bracket 20 and the shell 10 are enclosed to form a second accommodating cavity 102, wherein the first accommodating cavity 101 is connected to the suction nozzle 11, and the second accommodating cavity 102 is connected to the external atmosphere.

[0040] The atomizing device further comprises a suction nozzle 11 , in which at least two suction nozzle 11 air passages are provided, and each atomizing chamber 30 is provided with an atomizing air passage 32 , wherein the atomizing air passage 32 is communicated with the suction nozzle 11 air passage.

[0041] The atomizing chamber 30 is connected to the first side of the bracket 20, and is enclosed with the bracket 20 to form two air inlet chambers 301. The bracket 20 is provided with an air inlet channel 21 at the position corresponding to at least two atomizing air passages 32. The air inlet channel 21 is respectively connected to the atomizing air passage 32 and the second accommodating chamber 102, and each air inlet channel 21 can be selectively closed. Since the second accommodating chamber 102 is connected to the external atmosphere, when any air inlet channel 21 is opened, the external atmosphere can enter the air inlet chamber 301 through the air inlet channel 21. In practical applications, after entering the air inlet chamber 301, the gas can pass through the atomizing air passage 32 and the air passage of the suction nozzle 11 in sequence.

[0042] In some embodiments, the position where the second accommodating chamber 102 is connected to the external atmosphere is located at its bottom, and there is a gap between the bracket 20 and the shell 10, through which the external atmosphere can flow from the external atmosphere into the air inlet channel of the bracket; or, in some other embodiments, the position where the second accommodating chamber 102 is connected to the external atmosphere is located in the middle thereof, and the shell 10 is provided with an air inlet hole at this position of the second accommodating chamber 102, the bracket 20 is against the inner wall of the shell 10, and the air inlet channel 21 of the bracket 20 is abutted against and connected to the air inlet hole of the shell.

[0043] The bracket 20 is provided with at least one sensing air hole 22 penetrating the first side and the second side, and one end of the sensing air hole 22 is communicated with an atomizing air channel 32 of at least one atomizing bin 30 .

[0044] In one embodiment, the bracket 20 may be provided with one sensing air hole 22, wherein one sensing air hole 22 is located in one atomizing bin 30, and one end of the sensing air hole 22 is connected to the atomizing air passage 32, and the other end is connected to the air flow sensor 40; in another embodiment, the bracket 20 may be provided with two sensing air holes 22, wherein the projections of the two sensing air holes 22 in the first direction are respectively located in the two atomizing bins 30, and one end of the two sensing air holes 22 is respectively connected to the atomizing air passages 32 of the two atomizing bins 30, and the other end is connected to the air flow sensor 40, so that the external atmosphere can enter the two atomizing bins 30 through the two sensing air holes 22. Of course, the bracket 20 may also be provided with multiple sensing air holes 22, and this application does not specifically limit this.

[0045] The airflow sensor 40 is arranged on the second side of the bracket 20, and one side of the airflow sensor 40 is connected to the sensing air hole 22. The side of the airflow sensor 40 facing away from the sensing air hole 22 is located in the second accommodating cavity 102 to be connected to the external atmosphere. When the user performs the inhalation action, the airflow sensor 40 can detect the negative pressure, thereby triggering the device to heat the atomized matrix.

[0046] For example, Figure 8 The bracket 20 in the embodiment has a sensing air hole 22 on one side of the right side of the bracket 20, and the sensing air hole 22 is located in the right air inlet cavity 301. When the left air inlet channel 21 is closed, the right atomizing bin 30 takes in air through the right air inlet channel 21. Since the sensing air hole 22 is connected with the atomizing air passage 32 on the right side and the air inlet channel 21, when the user inhales at the mouthpiece 11, the external atmosphere flows into the atomizing air passage 32 from the air inlet channel 21, and forms a negative pressure in the sensing air hole 22. The airflow sensor 40 located at the lower part of the sensing air hole 22 is deformed upward, thereby generating a sensing signal, so that the airflow sensing and the air inlet cavity 301 can be realized at the same time. Although the atomizing air channel 32 in the air inlet cavity 301 on the left is also connected to the mouthpiece 11, since the air inlet channel 21 is closed, when the user inhales at the mouthpiece 11, negative pressure is formed in the atomizing air channel 32 on the left; and there is no deformable component in the air inlet channel 21, so the negative pressure in the atomizing air channel 32 on the left will not cause loss of suction resistance.

[0047] When the right air inlet channel 21 is closed, the left atomizing bin 30 takes in air through the left air inlet channel 21. Since the left side of the bracket 20 does not have a sensing air hole 22, the external atmosphere can only enter the atomizing air channel 32 in the right air inlet cavity 301 through the right sensing air hole 22. The atomizing air channels 32 in the left and right air inlet cavities 301 are both connected to the suction nozzle 11. The suction at the suction nozzle 11 will act on the two atomizing air channels 32 on the left and right sides at the same time; that is, the air inlet channel connected to the right atomizing air channel 32 21 is closed and air cannot be taken in, a negative pressure is formed in the atomizing airway 32 on the right side, and since the sensing air hole 22 is connected to the atomizing airway 32 on the right side, a negative pressure is also generated at the sensing air hole 22, and the air flow sensing and the air intake of the air intake chamber 301 can also be realized at the same time. It can be understood that in this embodiment, since the air intake channel 21 connected to the atomizing airway 32 on the right side is closed, the suction nozzle 11 is connected to the atomizing airway 32 on the right side to the position of the sensing air hole 22, which is equivalent to a sensing airway independent of the atomizing airway 32 on the left side. In addition, when the air intake channels 21 on both sides are opened, the atomizing bins 30 on both sides take in air through the air intake channels 21 on both sides, and at the same time, a negative pressure is generated at the sensing air hole 22 in the atomizing airway 32 on the right side, and the air intake and air flow sensing of the atomizing bin 30 can also be realized at the same time. Therefore, the atomization device provided in the embodiment of the present application can not only provide two atomization flavors, but also can simultaneously realize the air intake and airflow sensing functions of the atomization bin 30 under various air intake states of the air intake cavity 301 by setting an airflow sensor 40, thereby saving the internal space of the atomization device.

[0048] In an embodiment of the present application, the suction nozzle 11 is arranged on the shell 10. Further, the shell 10 may include an upper shell 10 and a lower shell 10, and the upper shell 10 and the lower shell 10 are connected to each other to form a accommodating cavity, wherein the upper shell 10 and the lower shell 10 can be connected by snapping or bonding. A suction nozzle 11 is provided at one end of the upper shell 10 away from the lower shell 10, and the user can suction through the suction nozzle 11 when using it. There are two atomization bins 30, and each atomization bin 30 can be provided with a liquid storage cotton, and the liquid storage cotton is used to store the atomization matrix. The atomization airway 32 is provided in the liquid storage cotton, and a heating component is provided in the atomization airway 32. The heating component can be used to heat and atomize the atomization matrix stored in the liquid storage cotton. The liquid storage cotton in the two atomization bins 30 can store atomization matrices of different flavors. In addition, an atomization bin 30 includes a sealing member 31 and an atomization air duct 32 at its lower portion. The sealing member 31 is disposed on one side of the atomization bin 30 close to the bracket 20 and is connected to the bracket 20 to enclose an air inlet cavity 301 with the first side of the bracket 20. The air inlet cavity 301 also connects the atomization air duct 32 and the air inlet channel 21.

[0049] Among them, one air inlet cavity 301 corresponds to one air inlet channel 21, so as to perform atomization operations independently. When the liquid storage cottons in the two atomization bins 30 store atomization matrices of different flavors, the atomization device can provide users with different atomization flavors and improve user experience. It can be understood that since the atomization bin 30 includes a sealing member 31, and the sealing member 31 is connected to the bracket 20 to enclose and form the air inlet cavity 301, the sealing effect of the air inlet cavity 301 can be better.

[0050] like Fig. 9 , Fig.10 As shown, a mounting cavity 24 is provided on the second side of the bracket 20. The mounting cavity 24 and the bracket 20 are an integrally formed structure, and the shape of the mounting cavity 24 is adapted to the shape of the airflow sensor 40. The portion of the sensing air hole 22 located on the first side of the bracket 20 is connected to the air inlet cavity 301, the atomization air duct 32, and the air duct of the suction nozzle 11 in sequence, and the portion located on the second side of the bracket 20 is connected to one side of the mounting cavity 24, and the airflow sensor 40 is accommodated in the mounting cavity 24.

[0051] In actual application, the user can perform a suction action through the nozzle 11. Since the airflow sensor 40 is arranged on the second side of the bracket 20, the airflow sensor 40 is actually located in the second accommodating chamber 102. Furthermore, the second accommodating chamber 102 is connected to the external atmosphere. Therefore, when the user inhales, the external atmosphere can pass through the installation cavity 24, the air inlet cavity 301, the atomization airway 32, the nozzle 11 airway in sequence to the nozzle 11, thereby generating a negative pressure on the top of the airflow sensor 40. The airflow sensor 40 detects the negative pressure, thereby triggering the heating component to heat and atomize the atomization matrix.

[0052] Since the installation cavity 24 is provided on the second side of the bracket 20 and the airflow sensor 40 is accommodated in the installation cavity 24, the airflow channel of the airflow sensor 40 is more accurate, and the sensitivity of the airflow sensor 40 in sensing airflow can be improved; in addition, since there are many internal components of the atomization device, connecting the airflow sensor 40 in the installation cavity 24 can isolate the airflow sensor 40 from other components, thereby playing a certain protective role on the structure of the airflow sensor 40.

[0053] In one embodiment, the atomization device also includes a shielding member 50, and the two air inlet channels 21 form two air inlets on the second side of the bracket 20. The shielding member 50 is movably connected to the bracket 20 to selectively close the air inlet corresponding to one of the air inlet channels 21, or to release the closure of the air inlets corresponding to the two air inlet channels 21.

[0054] like Figure 8As shown, the two air inlets formed by the two air inlet channels 21 on the bracket 20 are arranged in parallel, and the shielding member 50 is movably connected to the bracket 20 and can slide left and right. When the shielding member 50 slides to the left side of the bracket 20, the left air inlet is closed, the atomizing device takes in air through the right air inlet channel 21, and the right atomizing bin 30 works; when the shielding member 50 slides to the right side of the bracket 20, the right air inlet is closed, the atomizing device takes in air through the left air inlet channel 21, and the left atomizing bin 30 works; and when the shielding member 50 slides to the middle position of the bracket 20, the air inlets on both sides are exposed to the outside, and the atomizing device can take in air through the air inlet channels 21 on both sides at the same time. At this time, the two atomizing bins 30 can work at the same time.

[0055] In one embodiment, negative pressure is formed in the air inlet cavity 301 , the atomizing air channel 32 , and the air channel of the suction nozzle 11 which are in communication with the closed air inlet channel 21 .

[0056] Specifically, when the air inlet channel 21 on one side is closed, the user inhales at the nozzle 11, and the external atmosphere flows into the atomizing air channel 32 corresponding to the air inlet channel 21 on the side through the sensing air hole 22, and passes through the air inlet cavity 301, the atomizing air channel 32 and the air channel of the nozzle 11 in turn, and forms a negative pressure in the air inlet cavity 301, the atomizing air channel 32 and the air channel of the nozzle 11 on the side.

[0057] In one embodiment, the bracket 20 is provided with a sensing air hole 22, wherein the atomizing air duct 32 connected to the sensing air hole 22 is a first atomizing air duct 32, and the two ends of the first atomizing air duct 32 are respectively connected to the air duct of the first suction nozzle 11 and the first air inlet cavity 301, and the air inlet channel 21 connected to the first air inlet cavity 301 is the first air inlet channel 21; when the first air inlet channel 21 is closed, negative pressure is formed in the first air inlet cavity 301, the first atomizing air duct 32 and the air duct of the suction nozzle 11.

[0058] For example, Figure 8 As shown, a sensing air hole 22 is provided on the right side of the bracket 20, and the atomization bin 30 on the right side corresponding to the sensing air hole 22 is the first atomization bin 30, and a first atomization airway 32 is provided in the first atomization bin 30, and both ends of the first atomization airway 32 are connected to the first suction nozzle 11 airway and the first air inlet cavity 301, and the first air inlet cavity 301 is inhaled through the first air inlet channel 21. When the first air inlet channel 21 is closed, negative pressure is formed in the first air inlet cavity 301, the first atomization airway 32 and the suction nozzle 11 airway.

[0059] In one embodiment, the number of the sensing air holes 22 is at least two, and the at least two sensing air holes 22 are spaced apart on the bracket 20 and are respectively located in the two air inlet cavities 301 .

[0060] In actual applications, when each air inlet cavity 301 includes a sensing air hole 22, when any one of the air inlet channels 21 is opened, or when both air inlet channels 21 are opened, the sensing air hole 22 can enter the two air inlet cavities 301. Since the air inlet cavity 301 is connected to the suction nozzle 11, the airflow can be sensed by the airflow sensor 40.

[0061] For example, Figure 6 In the atomization device, if the left and right sides of the bracket 20 are provided with sensing air holes 22, and the sensing air holes 22 are respectively located in the air inlet cavities 301 on the left and right sides. When the left air inlet channel 21 is closed, the right atomization bin 30 takes in air through the right air inlet channel 21, and the external atmosphere enters the air inlet cavities 301 on both sides through the left sensing air holes 22 and the right sensing air holes 22, respectively. Although the atomization airway 32 in the air inlet cavity on the left is also connected to the suction nozzle 11, since its air inlet channel 21 is closed, when the user inhales at the suction nozzle 11, a negative pressure is formed in the atomization airway 32 on the left; and there is no deformable component in its air inlet channel 21, and the negative pressure in the atomization airway 32 on the left will not cause loss to the suction resistance, so that the airflow sensing and the air inlet cavity 301 can be realized at the same time.

[0062] Similarly, when the right air inlet channel 21 is closed, the left atomization bin 30 takes in air through the left air inlet channel 21, and the external atmosphere enters the air inlet cavities 301 on both sides through the left sensing air holes 22 and the right sensing air holes 22, respectively. Although the atomization air duct 32 in the right air inlet cavity is also connected to the suction nozzle 11, because its air inlet channel 21 is closed, when the user inhales at the suction nozzle 11, a negative pressure is formed in the atomization air duct 32 on the right; and there are no deformable parts in its air inlet channel 21, and the negative pressure in the atomization air duct 32 on the right will not cause loss to the suction resistance. In addition, when the air inlet channels 21 on both sides are opened, the atomization bins 30 on both sides take in air through the air inlet channels 21 on both sides, and at the same time, the external atmosphere enters the air inlet cavities 301 on both sides through the left sensing air holes 22 and the right sensing air holes 22, respectively, and the air intake and airflow sensing of the atomization bin 30 can also be realized simultaneously.

[0063] In one embodiment, the bracket 20 is further provided with an air inlet 23, and the shell 10 is provided with an opening. The air inlet 23 is arranged opposite to the opening and is at least partially exposed to the opening. The second accommodating cavity 102 is connected to the external atmosphere through the air inlet 23 and the opening.

[0064] like Figure 8 , Fig. 9As shown, the air inlet 23 is arranged between the air inlets on both sides. In actual application, the air inlet 23 is arranged opposite to the opening arranged on the shell 10, so that the external atmosphere can enter the second accommodating chamber 102 through the opening of the shell 10 and the air inlet 23 on the bracket 20 in sequence, so that the second accommodating chamber 102 is connected with the external atmosphere. Since the air intake in the second accommodating chamber 102 is used to sense the user's suction action, the bracket 20 is separately provided with an air inlet 23 for air intake, and the air inlet channel 21 of the air flow sensor 40 can be independent of the air inlet channel 21 of the atomization bin 30, and they do not interfere with each other, so that when the air inlet channels 21 of different atomization bins 30 are opened, the same air flow sensor 40 is used to realize the air flow sensing function.

[0065] In an optional embodiment, the air inlet hole 23 is disposed between the two air inlet ports, and the air inlet area of ​​the air inlet hole 23 is larger than the air inlet area of ​​the air inlet ports.

[0066] It should be noted that since the shielding member 50 is movably connected to the bracket 20 and is used to shield the two air inlets, the air inlet 23 is set between the two air inlets, so that the flow path between the air inlet 23 and the airflow sensor 40 can be shorter, and the airflow sensor 40 can be more sensitive to the airflow.

[0067] In the embodiment of the present application, the bracket 20 is interference fit with the shell 10. In practical applications, the bracket 20 can be interference fit with the shell 10 using a plastic part or a silicone part. It is understandable that when the bracket 20 and the shell 10 are interference fit, the bracket 20 and the inner wall of the shell 10 can be connected more tightly, the sealing between the first accommodating chamber 101 and the second accommodating chamber 102 is better, and the gas in the second accommodating chamber 102 is difficult to enter the first accommodating chamber 101 through the gap between the bracket 20 and the inner wall of the shell 10, which helps to improve the accuracy of the airflow sensor 40 in sensing the airflow. On the contrary, if the gas flow between the first accommodating chamber 101 and the second accommodating chamber 102 is good, when the user inhales, the gas may enter the first accommodating chamber 101 from the second accommodating chamber 102, resulting in a reduction in the airflow entering the air inlet chamber 301 through the sensing air hole 22, affecting the airflow sensor 40's sensing of the airflow.

[0068] In one embodiment, the bracket 20 includes a substrate 201 and a side plate 202, the substrate 201 includes a first side and a second side arranged in opposite directions along a first direction x, the side plate 202 is connected to the second side of the substrate 201, and the substrate 201, the side plate 202 and the shell 10 are enclosed to form a second accommodating cavity 102; the sensing air hole 22 is arranged on the substrate 201, the air inlet channel 21 is connected between the substrate 201 and the side plate 202, the atomization chamber 30 is connected to the first side of the substrate 201, and is enclosed with the first side of the substrate 201 to form an air inlet cavity 301, and the airflow sensor 40 is connected to the second side of the substrate 201.

[0069] Specifically, Figures 8 to 11 As shown, the substrate 201 and the side plate 202 are both configured to be thin plates, thereby saving the internal space of the atomization device, and since the side plate 202 is connected to the second side of the substrate 201, the atomized gas can enter the air inlet cavity 301 from the second accommodating cavity 102, thereby separating the air inlet channel 21 of the air inlet cavity 301 from the air inlet channel 21 of the air flow sensor 40.

[0070] In one embodiment, the two air inlet channels 21 form two air inlets on the side plate 202 , and the two air inlets are symmetrically arranged on the side plate 202 along the second direction y.

[0071] It is understandable that when the two air inlets are symmetrically arranged on the side plate 202, it is convenient for the layout design of the shielding member 50, and the air inlet paths of the two air inlets and the air inlet cavity 301 are the same, and the atomization effect can also be kept consistent.

[0072] In summary, the atomization device provided in the embodiment of the present application has at least the following technical effects:

[0073] The atomization device provided in the embodiment of the present application includes at least two atomization bins, and the bracket is provided with an air inlet channel at the position corresponding to each atomization bin. Since each air inlet channel can be selectively closed, each atomization bin can be inletted separately to realize the atomization function; in addition, each atomization bin is provided with an atomization airway, and each atomization airway is connected to the suction nozzle airway. When the user inhales at the suction nozzle, the external atmosphere can enter the atomization airway and the suction nozzle airway through the air inlet channel, and negative pressure can be formed in any atomization airway, and negative pressure is formed in the sensing air hole, and the airflow sensor is deformed to generate a sensing signal. Since the sensing air hole is connected to the atomization airway and forms an independent airflow channel of the airflow sensor, when any air inlet channel is opened, the airflow sensor can sense the airflow and generate a sensing signal. Therefore, only one airflow sensor is required to realize the airflow sensing in the case of multiple atomization bins, which simplifies the internal structure of the atomization device and can save more internal space to facilitate the spatial layout of the atomization device.

[0074] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
