[0002] Airflow sensors are often used as inhalation detection elements in atomizers. Specifically, when inhaling, the airflow sensor senses the negative pressure inside the atomizer, and the controller controls the atomizer core to start heating based on the voltage output by the airflow sensor.

Conventional airflow sensors are installed in the airway, making it easy for condensation generated in the airway to flow back into the airflow sensor, causing the airflow sensor to fail.

Similarly, the following examples are only some examples of the present application and not all examples. All other examples obtained by those of ordinary skill in the art without creative work are intended to fall within the scope of protection of this application.

[0037] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the atomization device in one embodiment of the present application. Figure 2 yes Figure 1 A cross-sectional view of the internal structure of the atomizing device in the embodiment, Figure 3 yes Figure 1Schematic diagram of the overall explosion of the atomizing device in the embodiment. The atomizing device may include an atomizing device and a power supply assembly 60. The atomizing device includes a housing 51, and a liquid storage tank 10, an atomizing core assembly 20, a sealing member 30, and an airflow sensor 41 arranged inside the housing 51. The liquid storage tank 10 is provided with a liquid storage chamber 11 for storing the atomizing matrix; the atomizing core assembly 20 is provided in the liquid storage chamber 11 and forms an atomizing channel 21. The atomizing core assembly 20 heats the atomizing matrix and forms an aerosol; the housing 51 is provided with a nozzle 53, which can be used by the user to inhale. 3 is connected to one end of the atomization channel 21 so that the aerosol can be transmitted to the suction nozzle 53 through the atomization channel 21 for the user to inhale. When the atomization device is not in operation, a suction nozzle plug 54 is inserted into the suction nozzle 53 to seal the atomization channel 21, thereby preventing external dust from entering the atomization channel 21, thereby maintaining the cleanliness of the atomization channel 21; the sealing member 30 and the liquid storage tank 10 are enclosed to form an air chamber 31, and the sealing member 30 includes a sensing channel 35, which is connected to the atomization channel 21 through the air chamber 31. The sensing channel 35 is connected to the atomization channel 21 through the air chamber 31. 5 is misaligned with the atomization channel 21; the airflow sensor 41 is arranged in the sealing member 30, and the airflow sensor 41 responds to the air pressure signal in the sensing channel 35 and outputs an electrical signal to the atomization device. The atomization device thus receives the electrical signal output by the airflow sensor 41 to control the working state of the atomization core assembly 20. Specifically, when the user inhales through the mouthpiece 53, the air pressure in the atomization channel 21 changes. Since the sensing channel 35 is connected to the atomization channel 21 through the air chamber 31, the air pressure in the sensing channel 35 changes with the air pressure in the atomization channel 21. The airflow sensor 41 responds to the air pressure signal in the sensing channel 35 and outputs an electrical signal. The atomization device controls the atomization core assembly 20 to be connected to the power supply assembly 60 according to the electrical signal output by the airflow sensor 41, and the atomization core assembly 20 can heat the atomization matrix to generate aerosol; when the user stops inhaling, the airflow sensor 41 does not sense the change in airflow within a preset time period, and the airflow sensor 41 controls the atomization core assembly 20 to be disconnected from the power supply assembly 60, and the atomization core assembly 20 stops heating.

[0039] See also Figure 2The power supply assembly 60 is disposed within the housing 51. The power supply assembly 60 provides electrical energy for the atomizer during operation. The power supply assembly 60 can be detachably connected to the atomizer, making it easy to replace the power supply assembly 60. For example, the power supply assembly 60 includes a battery cell 61 and a conductive spring 62. The battery cell 61 and the atomizer core assembly 20 are mounted side by side within the housing 51. That is, the extension direction of the battery cell 61 is the same as the extension direction of the atomizer channel 21. This can reduce the length of the atomizer and make full use of the lateral space to arrange the battery cell 61, which can adapt to atomizers with a wide and flat appearance. At the same time, the end of the shell 51 away from the suction nozzle 53 is detachably connected to the bottom cover 52. When the shell 51 and the bottom cover 52 are assembled together, the conductive spring 62 connects the atomizer core assembly 20 and the electrodes of the battery core 61 to achieve circuit conduction; when the shell 51 and the bottom cover 52 are separated, the conductive spring 62 is synchronously disconnected from the atomizer core assembly 20 and the battery core 61, thereby disconnecting the connection between the battery core 61 and the atomizer core assembly 20, making it convenient to replace the battery core 61, so that the atomizer device can be used multiple times, thereby reducing user costs.

[0040] In this embodiment, the seal 30 can be made of a material such as silicone with good compressibility. On the one hand, the seal 30 and the liquid storage tank 10 enclose an air chamber 31, which has a good sealing effect; on the other hand, the seal 30 forms a sensing channel 35, and a misalignment is formed between the sensing channel 35 and the atomization channel 21, thereby preventing the condensate in the atomization channel 21 from directly flowing back into the sensing channel 35, thereby reducing the risk of failure of the airflow sensor 41; the airflow sensor 41 is arranged in the seal 30, and the seal 30 can isolate and protect the airflow sensor 41 to avoid damage caused by hard contact between the airflow sensor 41 and other parts.

[0041] See also Figure 4 as well as Figure 5 , Figure 4 yes Figure 3 Schematic diagram of a partial explosion of the atomization device in the embodiment, Figure 5 yes Figure 4Partial cross-sectional view of the atomization device in the embodiment. In some embodiments, the liquid storage tank 10 is provided with a receiving groove 12, and the sealing member 30 is arranged in the receiving groove 12 and encloses the groove wall of the receiving groove 12 to form an air chamber 31. The liquid storage tank 10 includes a tank body 14, the tank body 14 includes a mounting portion 140 and a side plate 145 arranged around the mounting portion 140. The mounting portion 140 and the side plate 145 are an integral structure. A partition 143 is provided on the side of the mounting portion 140 facing away from the liquid storage chamber 11. The partition 143 separates the mounting portion 140 to form a first mounting area 141 and a second mounting area 142. The first mounting area 141, the partition and the side plate 145 enclose the receiving groove 12. The projections of the atomization channel 21 and the sealing member 30 on the first plane are located in the first mounting area 141. The first plane is a reference plane perpendicular to the axial direction of the atomization channel 21.

[0042] See also Figure 6 , Figure 6 yes Figure 4 Schematic diagram of the structure of the sealing member in the embodiment. The sealing member 30 includes a sealing portion 32 and an extension portion 33. The sealing portion 32 is fixedly fitted with the side plate 145 and the partition 143 of the liquid storage tank 10. The sealing portion 32, the first mounting area 141 of the mounting portion 140, the side plate 145 and the partition 143 enclose an air chamber 31. The extension portion 33 extends from the sealing portion 32 toward one side of the liquid storage chamber 11, and the sensing channel 35 passes through the extension portion 33. The misalignment between the sensing channel 35 and the atomization channel 21 refers to the fact that the projections of the sensing channel 35 and the atomization channel 21 on the first plane do not overlap. It can be understood that since the extension portion 33 extends from the sealing portion 32 toward the liquid storage chamber 11, the top of the extension portion 33 is higher than the top of the sealing portion 32, that is, the top of the sensing channel 35 is higher than the bottom of the air chamber 31. This can prevent the condensate formed in the atomization channel 21 from entering the sensing channel 35, thereby reducing the risk of failure of the airflow sensor 41. An avoidance groove 321 is provided on the sealing portion 32 , and the avoidance groove 321 is connected to the air chamber 31 through the sensing channel 35 . The airflow sensor 41 is accommodated in the avoidance groove 321 so that the airflow sensor 41 can quickly respond to the air pressure signal in the sensing channel 35 .

[0043] See also Figure 5A blind hole 1412 is formed on the side of the mounting portion 140 facing away from the liquid storage chamber 11, and the extension portion 33 extends into the blind hole 1412. A mounting groove 144 is formed on the side of the mounting portion 140 facing the liquid storage chamber 11, and the atomizer core assembly 20 is inserted into the mounting groove 144, with the mounting groove 144 and the blind hole 1412 being misaligned. By extending the extension portion 33 into the blind hole 1412, the distance from the top end of the extension portion 33 to the suction nozzle 53 is made smaller than the distance from the bottom end of the atomizer channel 21 to the suction nozzle 53. While maintaining gas flow between the sensing channel 35 and the atomizer channel 21, a bend is further formed between the ports connecting the sensing channel 35 and the atomizer channel 21, thereby reducing the entry of condensate into the sensing channel 35.

[0044] Please continue reading Figure 5 A limiting portion 1411 is provided in the first mounting area 141 of the mounting portion 140, which is used to limit the movement of the seal 30 in the direction close to the liquid storage chamber 11. The limiting portion 1411 can be in any shape such as a plate or a column, and is not specifically limited here. The limiting portion 1411 is fixedly connected to the mounting portion 140, and the seal 30 abuts against the limiting portion 1411 to form a gap between the seal 30 and the bottom wall of the receiving groove 12. Since the seal 30 and the groove wall of the receiving groove 12 enclose the air chamber 31, the limiting portion 1411 can install and position the seal 30, limit the movement of the seal 30 in the direction close to the liquid storage chamber 11, and avoid the reduction of the space of the air chamber 31 resulting in changes in the air pressure in the air chamber 31, thereby avoiding affecting the sensitivity of the air flow sensor 41 detection. Optionally, the limiting portion 1411 can also be fixedly set on the seal 30, and the limiting portion 1411 can be made of a different material from the seal 30. For example, the limiting portion 1411 is made of a material with higher hardness and less compressibility. During assembly, the limiting portion 1411 abuts against the bottom wall of the accommodating groove 12, thereby forming a gap between the seal 30 and the bottom wall of the accommodating groove 12.

[0045] In some embodiments, the sealing member 30 is provided with an air inlet pipe 34. One end of the air inlet pipe 34 communicates with the atomizing channel 21 through the air chamber 31, and the other end communicates with the outside air. The air inlet pipe 34, the extension portion 33, and the sealing portion 32 are integrally formed. The air inlet pipe 34 extends from the sealing portion 32 away from the liquid storage chamber 11. Outside air can directly enter the atomizing channel 21 through the air inlet pipe 34 and the air chamber 31. The air inlet pipe 34 forms an independent air inlet channel, which can prevent stray air from entering the atomizing channel 21 and meet the air supply needs of the user during inhalation. The projection of the air inlet pipe 34 and the atomizing channel 21 on the first plane overlaps, making the air flow smoother.

[0046] See also Figure 2 as well as Figure 4 In some embodiments, a circuit board 40 is provided on the side of the sealing member 30 facing away from the liquid storage chamber 11 , and the airflow sensor 41 is provided on the circuit board 40 , so as to facilitate modular assembly of components.

[0047] See also Figure 2 In particular, the atomization device also includes a power regulation module 44, which is used to adjust the power of the atomizer core assembly 20. The power regulation module 44 includes a button 441 and a key cover 442 that is linked to the button 441. The button 441 is integrated on the circuit board 40. In this embodiment, the button 441 is configured as a tactile switch, and the key cover 442 covers the button 441. Pressing the key cover 442 can control the action of the tactile switch. The action signal of the button 441 is input into the power regulation module 44, and the power regulation module 44 adjusts the voltage or current supplied to the atomizer core assembly 20, thereby changing the power of the atomizer core assembly 20. The power regulation module 44 of this embodiment uses a power regulation chip familiar to those skilled in the art, and will not be described in detail here.

[0048] See also Figure 7 , Figure 7 yes Figure 3 Schematic diagram of the bottom cover structure in this embodiment. In this embodiment, the key cover 442 is formed on the bottom cover 52 at the position corresponding to the key 441. The key cover 442 and the bottom cover 52 are integrally formed. The key cover 442 is configured as a cantilever structure on the bottom cover 52 that can be pressed and deformed. An air inlet 521 is formed between the periphery of the key cover 442 and the bottom cover 52. This eliminates the need to provide the air inlet 521 on the bottom cover 52 or the housing 51, ensuring the aesthetic appearance of the atomizer.

[0049] Also, see Figure 1 The housing 51 is provided with a display component 511. The information displayed by the display component 511 may include the remaining amount of atomizing matrix in the liquid storage chamber 11, the heating power of the atomizing core assembly 20, the power level of the battery 61, warning information, etc., so that the user can promptly understand the working status of the electronic atomizing device. For example, when the remaining amount of atomizing matrix in the atomizing core assembly 20 is less than a preset value, the display component 511 may display an oil level warning message to prompt the user to stop inhaling to prevent the atomizing core assembly 20 from burning dry and producing a burnt smell; or, when the power level of the battery 61 is less than a preset value, the display component 511 may display a power level warning message to prompt the user to charge or replace the battery 61 in time, thereby ensuring the normal operation of the atomizing device.

[0050] See also Figure 2 as well as Figure 4In some embodiments, the second mounting area 142 of the mounting portion 140 is provided with a pin hole 1421, which is used to pass the wires connecting the atomizer core assembly 20. The atomizer core assembly 20 includes an atomizer tube 23 and a heating element 22. The atomizer tube 23 has a certain rigidity. For example, the atomizer tube 23 can be made of a steel pipe. One end of the atomizer tube 23 is inserted into the mounting groove 144 to form an atomization channel 21. The heating element 22 is mounted on the atomizer tube 23. A liquid storage element is provided in the liquid storage chamber 11. The liquid storage element can be made of a porous material such as fiber cotton. The liquid storage element is arranged around the atomizer tube 23 and the heating element 22. The heating element 22 is used to heat the atomization matrix and form an aerosol. The heating element 22 passes through the pin hole 1421 through a wire and establishes an electrical connection with the circuit board 40. After the wire is passed through, the pin hole 1421 can be encapsulated with glue to prevent the atomization matrix from leaking from the pin hole 1421.

[0051] See also Figure 4 as well as Figure 5 Furthermore, a positioning groove 1422 is provided on the second mounting area 142 of the mounting portion 140. A first conductive electrode 42 is provided on the circuit board 40 and inserted into the positioning groove 1422. The first conductive electrode 42 is electrically connected to the heating element 22. The first conductive electrode 42 not only serves as a component for electrically connecting the circuit board 40 to the atomizer core assembly 20, but also serves to position the circuit board 40 for assembly.

[0052] By separating the mounting portion 140 to form a second mounting area 142 and a first mounting area 141, the atomizing channel 21 is correspondingly arranged in the first mounting area 141, and the pin hole 1421, the positioning groove 1422, etc. are correspondingly arranged in the second mounting area 142. Since the wires in the pin hole 1421 will be encapsulated after being passed through, and the positioning groove 1422 does not pass through the mounting portion 140, the second mounting area 142 does not need to be sealed by the seal 30, and the seal 30 only needs to seal the first mounting area 141. In other words, the seal 30 does not need to be in contact with the inner wall of the entire chamber body 14; as long as the contour of the sealing portion 32 matches the contour of the first mounting area 141, the space occupied by the seal 30 is small, and the second mounting area 142 forms the assembly space for the circuit board 40 and the atomizing core assembly 20, making full use of the lateral internal space of the atomizing device, optimizing the internal space of the atomizing device, making each component more compact, and reducing space occupation.

[0053] As mentioned above, the conductive spring 62 provided on the bottom cover 52 connects the atomizer core assembly 20 to the electrodes of the battery cell 61. Specifically, a second conductive electrode 43 is also provided on the circuit board 40. The second conductive electrode 43 extends from the side of the circuit board 40 facing away from the liquid storage chamber 11 in a direction away from the liquid storage chamber 11. The second conductive electrode 43 is used to establish an electrical connection between the circuit board 40 and the battery cell 61, that is, the second conductive electrode 43 is used to electrically connect the atomizer core assembly 20 and the battery cell 61. It will be understood that the conductive spring 62 uses a contact-type electrical connection to connect the second conductive electrode 43 and the battery cell 61. That is, when the bottom cover 52 and the outer shell 51 are assembled, the two ends of the conductive spring 62 contact the second conductive electrode 43 and the electrodes of the battery cell 61, respectively. When the bottom cover 52 and the outer shell 51 are separated, the conductive spring 62 no longer contacts the second conductive electrode 43 and the electrodes of the battery cell 61.

[0054] See also Figure 2 as well as Figure 8 , Figure 8 yes Figure 3 Schematic diagram of the structure of the bracket in the embodiment. Furthermore, a bracket 80 is provided on the side of the circuit board 40 facing away from the liquid storage chamber 11. The bracket 80 is provided with a plurality of mounting holes 81 to facilitate the installation and positioning of the second conductive electrode 43, the button 441, and the air inlet pipe 34. The air inlet pipe 34 passes through the circuit board 40 and plugs into the mounting holes 81 on the bracket 80 to form an independent air inlet duct, preventing the formation of air vortices in the space between the circuit board 40 and the bracket 80. The bracket 80 can be made of an insulating plastic material to isolate the second conductive electrode 43 and the button 441 from the surrounding electronic devices, preventing the electronic devices from being affected by long-term exposure.

[0055] See also Figure 9 as well as Figure 10 , Figure 9 yes Figure 3 Another partial explosion diagram of the atomizing device in the embodiment, Figure 10 yes Figure 9 A partial cross-sectional view of the atomization device in an embodiment. In some embodiments, the nozzle 53 is detachably connected to the housing 51, specifically by a snap-on connection, bolt connection, or the like. A liquid wicking member 70 is positioned between the liquid reservoir 10 and the nozzle 53. The wicking member 70 can be made of a material with excellent adsorption properties, such as fiber cotton, to absorb condensate. The ends of the wicking member 70 abut against the nozzle 53 and the liquid reservoir 10, respectively, for ease of assembly.

[0056] Optionally, the liquid storage tank 10 further includes a tank cover 13 that is detachably connected to the tank body 14, and the liquid absorbing member 70 is clamped between the tank cover 13 and the suction nozzle 53.
