Description

Technical Field

[0001] The present application relates to the field of aerosol generating devices, and in particular to an atomizer and an aerosol generating device. Background Art

[0002] A common aerosol-generating device consists of a mouthpiece, an atomizer, and a power supply assembly, each of which is connected to the atomizer. The atomizer has an air inlet channel on its surface and an atomization channel inside, connecting the air inlet channel to the mouthpiece. The atomization channel is equipped with a heating element for heating. During inhalation, external air enters the atomizer through the air inlet channel and then enters the atomization channel. The heating element atomizes the aerosol matrix stored in the atomizer, which is then discharged from the aerosol-generating device along with the air through the mouthpiece.

[0003] In related art, because the atomizer's air inlet channel isn't directly facing the atomization channel, the airflow direction changes significantly as it enters the atomization channel. Within the atomization channel, the airflow velocity on the side closest to the air inlet channel is slower than on the side farther from the channel. This airflow velocity affects the local temperature of the heater: areas with faster airflow have lower heater temperatures, while areas with slower airflow have higher heater temperatures. High-temperature areas age faster and have shorter lifespans, thus impacting the atomizer's service life. Utility Model Content

[0047] Figure 1 This is a schematic diagram of the structure of an aerosol generating device. Figure 1 As shown, the aerosol generating device includes an atomizer 100 and a power supply assembly 200 , and the atomizer 100 is connected to the power supply assembly 200 .

[0048] The atomizer 100 has an air inlet channel 100a and an atomization channel 100b, and the air inlet channel 100a and the atomization channel 100b are arranged in a staggered manner. A heating element 101 is arranged in the atomization channel 100b. The power supply component 200 includes a microphone 201, which is arranged near the entrance of the air inlet channel 100a. During the inhalation process, air enters the aerosol generating device, enters the atomizer 100 through the air inlet channel 100a, and then enters the atomization channel 100b. The airflow exchanges heat with the heating element 101 while flowing through the atomization channel 100b. The microphone 201 controls the operation of the atomizer 100 based on the air pressure near the entrance of the air inlet channel 100a.

[0049] Figure 2 yes Figure 1 A partial enlarged schematic diagram. Figure 2 Schematically shows the airflow at the entrance of the atomizing channel 100b. Figure 2 As shown, since the air inlet channel 100a is not directly opposite the atomizing channel 100b, the direction of the airflow at the entrance of the atomizing channel 100b will change. The airflow speed on the side of the atomizing channel 100b away from the air inlet channel 100a is faster, which will accelerate the heat dissipation of the heating element 101 and make the temperature of the heating element 101 at this location lower. The airflow speed on the side of the atomizing channel 100b close to the air inlet channel 100a is slower, and the temperature of the heating element 101 is higher. In other words, during operation, there will be a certain temperature difference on both sides of the heating element 101. The side with a higher temperature will age faster and have a shorter lifespan, thereby shortening the service life of the heating element 101 and affecting the service life of the atomizer 100.

[0050] Figure 3 This is a schematic diagram of the structure of an atomizer provided in an embodiment of the present application. Figure 3 As shown, the atomizer includes a housing assembly 10 and an atomizing assembly 20 .

[0051] Figure 4 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of the present application. Figure 4 As shown, the housing assembly 10 has a first air inlet channel 11a and a second air inlet channel 11b. The atomizer assembly 20 is located in the housing assembly 10. The atomizer assembly 20 is formed with an atomizer channel 100b. One end of the atomizer channel 100b is located between the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b, and is connected to the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b.

[0052] By providing the first air inlet channel 11a and the second air inlet channel 11b in the housing assembly 10 of the atomizer 100, one end of the atomizing channel 100b of the atomizing assembly 20 is located between the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b. Figure 5Schematic diagram of the airflow at the inlet of the atomizing channel of an atomizer provided in an embodiment of the present application. Figure 5 As shown, during the inhalation process, air can enter the atomizer from the first air inlet channel 11a and the second air inlet channel 11b, and then flow into the atomizing channel 100b. When the air entering the atomizer 100 from the first air inlet channel 11a enters the atomizing channel 100b, the airflow speed in the atomizing channel 100b is slower on the side close to the first air inlet channel 11a, and faster on the side away from the first air inlet channel 11a; when the air entering the atomizer 100 from the second air inlet channel 11b enters the atomizing channel 100b, the airflow speed in the atomizing channel 100b is slower on the side close to the second air inlet channel 11b, and faster on the side away from the second air inlet channel 11b. The air entering from the first air inlet channel 11a and the air entering from the second air inlet channel 11b converge at the atomizing channel 100b, so that in the atomizing channel 100b, the air flow velocity on the side close to the first air inlet channel 11a and the air flow velocity on the side close to the second air inlet channel 11b are slightly different, which can reduce the temperature difference in the local area of the heating element 101 and is beneficial to extending the service life of the atomizer 100.

[0053] like Figure 4 As shown, the housing assembly 10 includes a liquid tank housing 11 and a partition plate 12. The partition plate 12 is located in the liquid tank housing 11 and is arranged opposite to the bottom wall of the liquid tank housing 11. In the liquid tank housing 11, a liquid tank for accommodating an aerosol substrate is formed on a side of the partition plate 12 away from the bottom wall of the liquid tank housing 11.

[0054] As an example, the bottom wall of the liquid tank housing 11 and the side walls of the liquid tank housing 11 may be detachably connected, for example, by a snap connection.

[0055] In some other possible implementations, the bottom wall of the liquid storage housing 11 and the side walls of the liquid storage housing 11 may also be an integral structure.

[0056] The atomizing assembly 20 is located on a side of the isolation plate 12 away from the bottom wall of the liquid tank housing 11 .

[0057] Exemplarily, the atomizing assembly 20 includes a liquid storage member 21, a bracket 22, and a heating member 101. The bracket 22 forms an atomizing channel 100b and is surrounded by the liquid storage member 21. The heating member 101 is located in the bracket 22.

[0058] As an example, the atomization assembly 20 may further include a liquid guiding member 23, a portion of which is located in the atomization channel 100b and arranged around the heating member 101, and another portion of the liquid guiding member 23 is located outside the atomization channel 100b. The liquid guiding member 23 is used to allow the aerosol matrix to enter the atomization channel 100b.

[0059] like Figure 4As shown, the first air inlet channel 11a and the second air inlet channel 11b are located on the bottom wall of the liquid tank housing 11. The isolation plate 12 has a first through hole 12a, which is located between the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b. The atomization channel 100b is connected to the first through hole 12a.

[0060] The isolation plate 12 isolates the aerosol matrix, preventing it from leaking through the first air inlet channel 11a and the second air inlet channel 11b. The gap between the isolation plate 12 and the bottom wall of the liquid reservoir housing 11 connects the first air inlet channel 11a with the first through hole 12a, and the second air inlet channel 11b with the first through hole 12a, allowing air entering the atomizer through the first and second air inlet channels 11a and 11b to enter the atomizing channel 100b via the first through hole 12a.

[0061] The isolation plate 12 may have an insertion hole 12b on one side away from the bottom wall of the liquid tank housing 11. The insertion hole 12b is coaxially arranged with the first through hole 12a. The bracket 22 may be inserted into the insertion hole 12b.

[0062] The isolation plate 12 can be sealed against the inner wall of the liquid tank housing 11 to prevent leakage of the aerosol matrix therebetween. The isolation plate 12 can also be sealed against the bracket 22 to prevent leakage of the aerosol matrix therebetween.

[0063] In some examples, sealing rings may be provided between the isolation plate 12 and the inner wall of the liquid tank housing 11 , and between the isolation plate 12 and the bracket 22 .

[0064] In other examples, the isolation plate 12 may be an elastic member to achieve a sealed fit through its own elastic deformation. For example, the isolation plate 12 may be a silicone structural member.

[0065] Figure 6 This is a schematic structural diagram of an isolation plate provided in an embodiment of the present application. Figure 6 As shown, the isolation plate 12 has a first groove 12c, which is located on one side of the isolation plate 12 close to the bottom wall of the liquid tank housing 11. The first through hole 12a is located in the first groove 12c, and the first air inlet channel 11a and the second air inlet channel 11b are respectively connected to the first groove 12c.

[0066] The first and second air inlet channels 11a and 11b have relatively small inner diameters, resulting in high air velocity and unstable airflow when the air flows through them. The first groove 12c provides a relatively large space, which can slow down the air flow and stabilize the airflow, thereby making the airflow smoother when passing through the first through hole 12a and into the atomizing channel 100b.

[0067] As an example, the outlet of the first air intake passage 11 a , the outlet of the second air intake passage 11 b , and the inlet of the first through hole 12 a are arranged on the same line.

[0068] The outlet of the first air inlet channel 11a, the outlet of the second air inlet channel 11b, and the inlet of the first through hole 12a are collinear, which means that the geometric center of the outlet of the first air inlet channel 11a, the geometric center of the outlet of the second air inlet channel 11b, and the collective center of the inlet of the first through hole 12a, the three's direct projections on the bottom wall of the liquid tank shell 11 are collinear.

[0069] That is to say, the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b are located on opposite sides of the first through hole 12a. The area with the fastest flow rate when the air flows from the first air inlet channel 11a into the atomizing channel 100b is the area with the slowest flow rate when the air flows from the second air inlet channel 11b into the atomizing channel 100b. The area with the slowest flow rate when the air flows from the first air inlet channel 11a into the atomizing channel 100b is the area with the fastest flow rate when the air flows from the second air inlet channel 11b into the atomizing channel 100b. This makes the flow rate of the airflow more uniform at the entrance of the atomizing channel 100b, and the difference in flow rate on both sides is smaller, which is conducive to further reducing the temperature difference on both sides of the heating element 101 and avoiding excessive temperature in local areas of the heating element 101 and shortening its service life.

[0070] like Figure 4 As shown, the bottom wall of the liquid tank housing 11 has a microphone hole 11 c, and the microphone hole 11 c is located between the second air inlet channel 11 b and the first through hole 12 a.

[0071] In the aerosol generating device, the microphone hole 11c is used to connect the atomizer 100 and the power supply assembly 200. During the inhalation process, the air pressure in the microphone hole 11c will change. The microphone in the power supply assembly 200 can control the operation of the aerosol generating device based on the air pressure in the microphone hole 11c.

[0072] for Figure 1 As can be seen, in the related art, microphone 201 is positioned adjacent to air inlet channel 100a, and controls the operation of the aerosol generating device based on the air pressure in air inlet channel 100a. However, during inhalation, the gas flow in air inlet channel 100a is high, the flow velocity is fast, and the velocity changes rapidly. This leads to unstable airflow and pressure in air inlet channel 100a, which affects the response of microphone 201 to pressure, resulting in reduced sensitivity of microphone 201 and abnormal operation of the aerosol generating device.

[0073] In this example, by providing an independent microphone hole 11c, the air pressure in the microphone hole 11c is less affected by the airflow in the first air inlet channel 11a and the second air inlet channel 11b. By using the microphone hole 11c in conjunction with the microphone, the microphone can more accurately control the operation of the aerosol generating device based on air pressure.

[0074] Figure 7 This is a schematic diagram of the structure of the bottom wall of a liquid tank shell provided in an embodiment of the present application. Figure 7 As shown, Figure 7 As shown, the inner diameter of the first air inlet passage 11a is larger than the inner diameter of the second air inlet passage 11b. Figure 4 As shown, the distance from the outlet of the first air inlet passage 11 a to the inlet of the first through hole 12 a is smaller than the distance from the outlet of the second air inlet passage 11 b to the inlet of the first through hole 12 a .

[0075] Because the inner diameter of the first air inlet channel 11a is larger than that of the second air inlet channel 11b, and the outlet of the first air inlet channel 11a is closer to the inlet of the first through hole 12a, during the inhalation process, the airflow through the first air inlet channel 11a encounters less resistance, making it easier for gas to enter the atomizer through the first air inlet channel 11a. The inner diameter of the second air inlet channel 11b is smaller, and the airflow encounters greater resistance when entering the atomizing channel 100b through the second air inlet channel 11b. This results in a smaller airflow volume, a slower flow rate, and a smoother gas flow. This makes it easier to form a relatively stable negative pressure at the microphone hole 11c, allowing the microphone to more accurately control the operation of the aerosol generating device based on air pressure.

[0076] like Figure 4 As shown, the atomizer may further include a suction nozzle 30, which is located on a side of the atomizing assembly 20 away from the isolation plate 12. The suction nozzle 30 is connected to the housing assembly 10. The suction nozzle 30 is communicated with the atomizing channel 100b.

[0077] As an example, the housing assembly 10 further includes a first shell 13. The first shell 13 may be cylindrical and sleeved outside the liquid tank housing 11. One end of the first shell 13 may be connected to the suction nozzle 30.

[0078] Figure 8 Schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application. Figure 8 As shown, the aerosol generating device includes a nebulizer 100 and a power supply component 200. The power supply component 200 is used to supply power to the nebulizer 100. The nebulizer 100 can be Figures 3 to 7 Any of the atomizers 100 shown.

[0079] In this example, by setting the first air inlet channel 11a and the second air inlet channel 11b in the shell assembly 10 of the atomizer 100, one end of the atomizing channel 100b of the atomizing assembly 20 is located between the outlet of the first air inlet channel 11a and the outlet of the second air inlet channel 11b. During the inhalation process, air can enter the atomizer from the first air inlet channel 11a and the second air inlet channel 11b, and then flow into the atomizing channel 100b. When the air entering the atomizer 100 from the first air inlet channel 11a enters the atomizing channel 100b, the air flow speed on the side close to the first air inlet channel 11a in the atomizing channel 100b is slower, and the air flow speed on the side away from the first air inlet channel 11a is faster; when the air entering the atomizer 100 from the second air inlet channel 11b enters the atomizing channel 100b, the air flow speed on the side close to the second air inlet channel 11b in the atomizing channel 100b is slower, and the air flow speed on the side away from the second air inlet channel 11b is faster. The air entering from the first air inlet channel 11a and the air entering from the second air inlet channel 11b converge at the atomizing channel 100b, so that in the atomizing channel 100b, the air flow velocity on the side close to the first air inlet channel 11a and the air flow velocity on the side close to the second air inlet channel 11b are slightly different, which can reduce the temperature difference in the local area of the heating element 101 and is beneficial to extending the service life of the atomizer 100.

[0080] Figure 9 This is a schematic diagram of the structure of a power supply component provided in an embodiment of the present application. Figure 9 As shown, the power supply assembly 200 may include a connector 31, a second housing 32, and a circuit structure. The second housing 32 has an open docking port for accommodating the atomizer 100. The connector 31 and the circuit structure are located within the second housing 32, with the circuit structure located on a side of the connector 31 away from the docking port.

[0081] The connecting seat 31 can be detachably connected to the housing assembly 10 of the atomizer 100 . For example, the connecting seat 31 can be used to be connected to the bottom wall of the liquid tank housing 11 .

[0082] The circuit structure may include a battery 33 , a circuit board 34 and a microphone 201 . The microphone 201 is disposed on the circuit board 34 , and the battery 33 is electrically connected to the circuit board 34 .

[0083] Figure 10 This is a schematic diagram of the structure of a power supply component provided in an embodiment of the present application. Figure 10 At least the second housing 32 is omitted. Figure 10As shown, the connection base 31 of the power supply assembly 200 has a second groove 31a and an air inlet 31b. The second groove 31a is located on the side of the connection base 31 close to the housing assembly 10, and the air inlet 31b is located at the bottom of the second groove 31a. The first air inlet channel 11a and the second air inlet channel 11b are connected to the second groove 31a.

[0084] After the connecting base 31 is connected to the shell assembly 10, the first air inlet channel 11a and the second air inlet channel 11b are both connected to the second groove 31a. During the suction process, air enters the second groove 31a through the air inlet hole 31b, and then enters the atomizer 100 through the first air inlet channel 11a and the second air inlet channel 11b. The second groove 31a allows the connecting base 31 to only be arranged with one air inlet hole 31b, without having to arrange multiple air inlet holes 31b. In addition, for different atomizers 100, the positions of the first air inlet channel 11a and the second air inlet channel 11b may be different. By arranging the second groove 31a, even if a different atomizer 100 is replaced, air can smoothly enter the first air inlet channel 11a and the second air inlet channel 11b during the suction process.

[0085] like Figure 10 As shown, the side of the connecting seat 31 away from the shell assembly 10 can be connected to the air intake pipe 311, one end of the air intake pipe 311 is connected to the air intake hole 31b, and the other end of the air intake pipe 311 can extend to the outside of the second shell 32, or the second shell 32 can have a third through hole, and the other end of the air intake pipe 311 can be connected to the third through hole.

[0086] As an example, the connecting seat 31 and the bottom wall of the liquid tank housing 11 can be connected by magnetic attraction to facilitate the replacement of the atomizer 100.

[0087] In other examples, the power supply assembly may also be fixedly connected to the atomizer 100. For example, the connection base 31 and / or the second shell 32 and the liquid tank housing 11 of the atomizer 100 are an integrated structure.

[0088] like Figure 10 As shown, the connecting base 31 further has a second through hole 31 c, and the second through hole 31 c is located at the bottom of the second groove 31 a.

[0089] The power supply assembly 200 further includes a microphone seat 35. At least a portion of the microphone seat 35 is located in the second through hole 31c and is sealed with the housing assembly 10. The microphone 201 is located on a side of the connecting base 31 away from the housing assembly 10 and is located in the microphone seat 35.

[0090] After the atomizer 100 and the power supply assembly 200 are assembled together, the second through hole 31c is aligned with the microphone hole 11c on the bottom wall of the liquid tank housing 11. The microphone 201 is connected to the circuit board 34 and is located in the microphone seat 35, which acts as a seal.

[0091] During the suction process, the air pressure at microphone hole 11c on the bottom wall of liquid tank housing 11 changes. Microphone 201 is used to detect the air pressure at microphone hole 11c. Microphone base 35 is sealed with housing assembly 10 to prevent the air pressure in second groove 31a from affecting the detection of microphone 201, thereby improving the accuracy and sensitivity of microphone 201's detection.

[0092] like Figure 10 As shown, the microphone base 35 includes a main body 351, a connecting portion 352, and a sealing edge 353. The main body 351 is located on the side of the connecting base 31 away from the housing assembly 10. The connecting portion 352 is located in the second through hole 31c and is connected to the main body 351 at one end. The sealing edge 353 is located at the end of the connecting portion 352 away from the main body 351 and is in contact with the housing assembly 10.

[0093] After the atomizer 100 and the power supply assembly 200 are assembled together, the sealing edge 353 contacts the bottom wall of the liquid tank shell 11. Under the action of squeezing, the sealing edge 353 is tightly attached to the bottom wall surface of the liquid tank shell 11, thereby forming a seal, allowing the microphone 201 to more accurately detect the pressure at the microphone hole 11c.

[0094] like Figure 10 As shown, the communication portion 352 may be tubular, and the communication portion 352 and the second through hole 31 c may be interference fit.

[0095] In some examples, the microphone base 35 may be an elastic member. Under the elastic force of the microphone base 35, the main body 351 is in contact with the surface of the circuit board 34, thereby reducing leakage between the contact surface of the main body 351 and the circuit board 34. For example, the microphone base 35 may be a silicone structural member.
