[0045] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0047] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0048] In previous atomization devices, the atomization channel through which the aerosol passes and the airflow channel used to trigger the airflow sensor are the same channel. The aerosol is easy to condense at the channel outlet and then flow back to the airflow sensor, causing corrosion of the airflow sensor, which can easily cause the risk of failure or self-start of the airflow sensor, further reducing its service life.

[0049] It can be understood that in the related art, a trigger hole is usually provided in the air flow channel for outputting aerosol in the atomization device, and an air flow sensor is installed on the outside of the trigger hole. The air flow sensor is prone to corrosion during backblowing, which leads to failure, causing self-start or failure defects, thereby causing a decrease in sensitivity.

[0050] See also Figure 1-Figure 7 , Figure 10-15 As shown, the atomizer provided in this embodiment includes: a housing 10 , a sealing body 20 , a liquid storage component 30 , an atomizing assembly 40 and an airflow sensor 50 .

[0051] like Figure 3-Figure 7 , Figure 11-Figure 15As shown, the bottom of the housing 10 is provided with an opening 11, the top of the housing 10 is provided with an atomization air outlet 12 and a first detection air hole 13, and the closing body 20 cooperates with the opening 11 of the housing 10, so that the closing body 20 and the housing 10 enclose a mounting cavity 100. Figure 2 As shown, the shell 10 and / or the enclosure 20 are provided with an atomizing air inlet 14. In other words, the atomizing air inlet 14 can be provided on the shell 10, or on the enclosure 20, or, the atomizing air inlet 14 is provided between the shell 10 and the enclosure 20. The enclosure 20 is provided with a second detection air hole 21, and a mounting groove 22 is provided on the side of the enclosure 20 away from the mounting cavity 100. The second detection air hole 21 passes through the mounting groove 22, and the airflow sensor 50 is arranged in the mounting groove 22. The interior of the shell 10 is provided with a detection air channel 15, and the detection air channel 15 is connected with the second detection air hole 21 and the first detection air hole 13. The enclosure 20 can be made of silicone material, so that it can be better sealed with the bottom opening of the shell 10.

[0052] The liquid storage component 30 and the atomization component 40 are both arranged in the installation cavity 100, and the atomization component 40 is connected to the atomization air inlet hole 14 and the atomization air outlet hole 12. The liquid storage component 30 is used to store the atomization matrix. The atomization component 40 is connected to the airflow sensor 50. The atomization component 40 is used to heat the atomization matrix to generate an aerosol.

[0053] It should be noted that the airflow sensor 50 can generate a trigger signal according to the change in the size and / or direction of the airflow, and the trigger signal can control the operation of the atomization component 40 to heat the atomization matrix to generate aerosol.

[0054] In a specific embodiment, the user inhales into the atomizing air outlet 12 and the first detecting air hole 13, and the outside air enters through the atomizing air inlet 14. At the same time, the detecting air duct 15 generates a certain negative pressure inside thereof under the action of inhalation. The negative pressure can generate a trigger signal through the second detecting air hole 22 to enable the air flow sensor 50 installed in the mounting groove 22. The trigger signal controls the atomizing component 40 to work so as to heat the atomizing matrix to generate an aerosol, wherein the aerosol is output through the atomizing air outlet 12 under the action of the outside air entering through the atomizing air inlet 14.

[0055] As described above, the atomizing air inlet 14, the atomizing assembly 40 and the atomizing air outlet 12 form a channel for aerosol output, and the second detection air hole 22, the detection air channel 15 and the first detection air hole 13 form a channel for negative pressure airflow flow. The two channels are relatively independent. In this way, the condensate formed by the aerosol at the atomizing air outlet 12 is not easy to flow back to the airflow sensor 50, thereby effectively extending the service life of the airflow sensor 50.

[0056] In some embodiments, the second detection air hole 22 is connected to the outside atmosphere. When the user inhales into the atomization air outlet hole 12 and the first detection air hole 13, the outside air enters through the atomization air inlet hole 14 and also enters the detection air duct 14 through the second detection air hole 22, so that the airflow sensor 50 senses the airflow change and can also generate a trigger signal to trigger the atomization component 40 to work.

[0057] In order to facilitate the user to inhale the atomizing air outlet 12 and the first detecting air hole 13, the atomizer provided in this embodiment also includes a suction nozzle 60, and the suction nozzle 60 is provided with an atomizing air channel 61 and a sensing air channel 62 running through the interior thereof. Of course, the atomizing air channel 61 and the sensing air channel 62 are arranged inside the suction nozzle 60 at intervals, and the two are relatively isolated. The suction nozzle 60 is connected to the top of the shell 10, and the top of the shell 10 is a side where the atomizing air outlet 12 and the first detecting air hole 13 are arranged, the atomizing air channel 61 is connected to the atomizing air outlet 12, and the sensing air channel 62 is connected to the first detecting air hole 13.

[0058] When the user inhales through the nozzle 60, he can simultaneously inhale towards the atomizing airway 61 and the sensing airway 62. The inhaled airflow flows through the atomizing airway 61, the atomizing air outlet 12, the atomizing component 40, and the atomizing air inlet 14, and allows external gas to enter through the atomizing air inlet 14. At the same time, the inhaled airflow flows through the sensing airway 62, the first detection air hole 13, the detection airway 15, and the second detection air hole 22, and the detection airway 15 generates a certain negative pressure inside thereof under the action of inhalation. The negative pressure can generate a trigger signal through the second detection air hole 22 to enable the airflow sensor 50 installed in the mounting groove 22. The trigger signal controls the operation of the atomizing component 40 to heat the atomizing matrix to generate an aerosol, wherein the aerosol is output from the atomizing airway 61 through the atomizing air outlet 12 under the action of the external gas entering through the atomizing air inlet 14.

[0059] Of course, in one embodiment, the detection airway 15 may also be a positive pressure airway. Specifically, Fig.11 A gap is set between the side wall of the airflow sensor 50 and the accommodating groove 18, and the airflow sensor 50 can adopt a capacitive sensor, whose deformable diaphragm is located at the lower part of the airflow sensor 50. Then, when the user sucks through the suction nozzle 60, the airflow impacts the deformable diaphragm at the lower part of the airflow sensor 50 and flows out through the gap between the airflow sensor 50 and the accommodating groove 18, and in turn passes through the second detection air hole 21, the detection air channel 15 defined between the first partition plate 151 and the second partition plate 152, the first detection air hole 13, the airflow channel 161, and the sensing air channel 62 of the suction nozzle 60.

[0060] In this embodiment, in order to improve the sealing performance between the first detection air hole 13 and the sensing air channel 62, as shown in FIG. Figure 2 , Figure 4 and Fig.11 As shown, a positioning column 16 is further provided on the side of the shell 10 facing the suction nozzle 60, that is, a positioning column 16 is provided on the top of the shell 10, so that the positioning column 16 located on the outside of the top of the shell 10 can cooperate with the suction nozzle 60. Specifically, the positioning column 16 is provided with an air flow channel 161 running through the interior thereof along its axial direction, and the air flow channel 161 is connected to the first detection air hole 13. The positioning column 16 is installed in the sensing air channel 62. In a specific embodiment, the positioning column 16 and the sensing air channel 62 are interference fit.

[0061] In one embodiment of the present application, a positioning channel 63 is also provided on the suction nozzle 60, and the positioning channel 63 is also set through the suction nozzle 60. Correspondingly, a spare positioning column 17 is also provided on the side of the shell 10 facing the suction nozzle 60. When the suction nozzle 60 is installed to the other side of the shell 10, the spare positioning column 17 is inserted into the positioning channel 63 to position the connection between the suction nozzle 60 and the shell 10.

[0062] In this embodiment, the positioning channel 63 and the sensing air channel 62 are symmetrical about the atomizing air channel 61 , and correspondingly, the spare positioning column 17 and the positioning column 16 are symmetrical about the atomizing air outlet 12 , thereby improving the aesthetics of the suction nozzle 60 .

[0063] In one embodiment, if Figure 2 and Fig.11 As shown, a sealing member 64 is also provided between the suction nozzle 60 and the other side of the housing 10. Figure 4 As shown, a receiving groove 18 is further provided on the other side of the shell 10 , a seal 64 is installed in the receiving groove 18 , and the suction nozzle 60 is connected to the other side of the shell 10 , so that the gap between the suction nozzle 60 and the other side of the shell 10 can be sealed by the seal 64 .

[0064] It should be noted that the seal 64 is a block structure, which is provided with avoidance holes that can avoid the atomization air outlet 12, the positioning column 16 and the spare positioning column 17. Of course, in other embodiments, the seal 64 can also be annular, and correspondingly, the accommodating groove 18 is also annular, which can also play a sealing role.

[0065] In one embodiment, if Figure 3 and Figure 5 As shown, the shell 10 is provided with a first partition 151 and a second partition 152 extending from the inner side of the top toward the bottom, and both sides of the first partition 151 and the second partition 152 are connected to the opposite side walls of the shell 10, wherein the opposite sides of the shell 10 are two side edges adjacent to the opening 11 and opposite to each other, so that the interval space between the first partition 151 and the second partition 152 defines the detection airway 15.

[0066] In this embodiment, the first partition 151 and the second partition 152 are arranged to separate the installation cavity 100 into two spaces, and the liquid storage component 30 is arranged on a side that ends at the first partition 151 and is away from the detection airway 15, and the atomization component 40 is arranged on this side. Of course, in other embodiments, if the atomization component 40 is arranged on a side that ends at the second partition 152 and is away from the detection airway 15, the liquid storage component 30 can also be arranged in the space on this side, and the specific selection is made according to actual needs.

[0067] When the sealing member 20 is installed at the opening 11 on one side of the housing 10, it is necessary to keep the detection air passage 15 and the second detection air hole 21 sealed. Figure 3 and Figure 6 As shown, a first groove 211 and a second groove 212 are further provided on the side of the closing body 20 facing the shell 10, the first partition plate 151 is sealed and connected to the first groove 211 by interference fit and plugging in the first groove 211, the second partition plate 212 is sealed and connected to the second groove 212 by interference fit and plugging in the second groove 212, and the second detection air hole 21 is located in the area between the first groove 211 and the second groove 212, so that the detection air channel 15 and the second detection air hole 21 are sealed and connected.

[0068] like Figure 3 As shown, the liquid storage component 30 is provided with a mounting channel 31 , and the atomizer assembly 40 is mounted in the mounting channel 31 . The mounting channel 31 forms an installation space for avoiding the atomizer assembly 40 , thereby facilitating the installation of the atomizer assembly 40 .

[0069] In another embodiment, if Fig.12 and Fig.13 As shown, a conducting tube 19 is provided inside the housing 10 , and the inner cavity of the conducting tube 19 defines a detection air channel 15 . The conducting tube 19 is sealedly connected to the second detection air hole 21 .

[0070] In a specific embodiment, a sealing groove 23 is further provided on the side of the closure member 20 facing the shell 10, wherein the second detection air hole 21 passes through the sealing groove 23, so that the conducting tube 19 can be inserted into the sealing groove 23 and maintain an interference fit connection relationship, so that the conducting tube 19 is sealed and connected to the second detection air hole 21.

[0071] Accordingly, in order to avoid the guide tube 19 and the atomization assembly 40, as shown in FIG. Fig.12 As shown, the liquid storage component 30 is provided with a first installation channel 32 and a second installation channel 33, both of which penetrate the liquid storage component 30, the atomization component 40 is arranged in the first installation channel 32, and the conducting tube 19 is arranged in the second installation channel 33, the first installation channel 32 forms an avoidance space for the atomization component 40, and the second installation channel 33 forms an avoidance space for the conducting tube 19.

[0072] like Figure 3 and Fig.12 As shown, the atomization assembly 40 includes an atomization tube 41, a heating element 42 and a liquid guiding element 43. The two ends of the atomization tube 41 are respectively connected to the atomization air inlet 14 and the atomization air outlet 12. The atomization tube 41 is provided with an extension port (not shown in the figure). The heating element 42 and the liquid guiding element 43 are both installed inside the atomization tube 41, and the liquid guiding element 42 extends to the outside of the atomization tube 41 through the extension port to contact with the liquid storage element 20, so that the atomization matrix can be conducted to the heating element 42 in an infiltration manner through the liquid guiding element 43, and the heating element 42 can heat the atomization matrix and atomize it into an aerosol by heating.

[0073] In this embodiment, the airflow sensor 50 is specifically connected to the heating element 42, and the trigger signal is used to trigger the operation of the heating element 42. The sum of the length of the atomizing airway 61 and the length of the atomizing tube 41 is greater than the sum of the length of the sensing airway 62 and the length of the detection airway 15. In this way, when the user inhales through the mouthpiece 60, the airflow sensor 50 can sense the change in air pressure and generate a trigger signal earlier than the time when the outside atmosphere enters through the atomizing air inlet 14.

[0074] In one embodiment of the present application, see Figure 6 and Figure 7 , Fig.14 and Fig.15 As shown, a mounting hole 24 is provided on the side of the closure member 20 facing the shell 10, and a connecting hole 25 is provided on the side of the closure member 20 away from the shell 10. The connecting hole 25 is connected to the atomization air inlet hole 14, and the connection method can be achieved by any method such as a pipeline, which is not limited here.

[0075] In this embodiment, the connecting hole 25 is also connected to the mounting hole 24, one end of the atomizer tube 41 is inserted into the mounting hole 24 with an interference fit, and the other end of the atomizer tube 41 is connected to the atomizer air outlet hole 12 with an interference fit, so that the two ends of the atomizer tube 41 are connected to the atomizer air inlet hole 14 and the atomizer air outlet hole 12 respectively.

[0076] See also Figure 1 and Figure 2 , Figure 8-Figure 11 ,and Fig.16 and Fig.17 As shown, this embodiment also provides an atomizing device, which includes: the atomizer in the above embodiment also includes: a power supply component 70 and a liquid storage component 80, the power supply component 70 is fixedly connected to the closed body 20 and is electrically connected to the atomizing component 40, as shown in FIG. Figure 8 and Fig. 9 , Fig.16 and Fig.17 As shown, the liquid storage assembly 80 can be detachably connected to the closed body 20, such as Figure 7 and Fig.15 As shown, the closing body 20 is provided with a liquid inlet 26 , and the liquid storage assembly 80 can provide the atomized matrix to the liquid storage member 30 through the liquid inlet 26 .

[0077] In a specific embodiment, the enclosing body 20 is further provided with a liquid inlet groove 27, the bottom of the liquid inlet groove 27 is a liquid inlet 26, and the liquid storage component 80 has a liquid supply end 81, and the liquid supply end 81 is installed at the liquid inlet groove 27 to realize the installation of the liquid outlet component 80. The liquid storage component 80 is mainly used to provide an atomized matrix to the liquid storage part 30, and the atomized matrix is ​​stored therein. With such an installation method, after the atomized matrix is ​​used up, the user's usage cost can be reduced by replacing a new liquid storage component 80.

[0078] In summary, in the atomizer and atomizing device provided by the present application, the user inhales the atomizing air outlet and the first detection air hole in the form of inhalation, and the external gas enters through the atomizing air inlet, and at the same time, the detection airway generates a certain negative pressure inside it under the action of inhalation, and the negative pressure can generate a trigger signal for the airflow sensor installed in the mounting groove through the second detection air hole, and the trigger signal controls the operation of the atomizing component to heat the atomizing matrix to generate an aerosol, wherein the aerosol is output through the atomizing air outlet under the action of the external gas entering through the atomizing air inlet. The atomizing air inlet, the atomizing component and the atomizing air outlet form a channel for aerosol output, and the second detection air hole, the detection airway and the first detection air hole form a channel for negative pressure airflow flow, and the two channels are relatively independent, so that the condensate formed by the aerosol at the atomizing air outlet is not easy to flow back to the airflow sensor, thereby effectively extending the service life of the airflow sensor.

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.
