Description

Technical Field

[0002] An aerosol generating device is a device used to heat an aerosol generating product to generate an aerosol for the user to inhale. The aerosol generating device usually includes an airflow channel for circulating the aerosol and an atomizing core for heating the aerosol generating product to generate the aerosol.

The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0038] See also Figures 1 to 3 The embodiment of the utility model provides an aerosol generating device 100, comprising a shell 1, a bracket 2 and an atomizing core 3, the shell 1 comprising an air outlet 11; the bracket 2 is installed inside the shell 1, and the bracket 2 defines a liquid storage chamber 21 for storing a liquid matrix; an air flow channel 22 defined by the bracket 2 or defined by the bracket 2 and the shell 1 is provided inside the shell 1, the air flow channel 22 is located at one side of the liquid storage chamber 21, the air flow channel 22 extends along a first direction X and the air outlet 11 is located at one end of the air flow channel 22, the air outlet 11 and the air flow channel 22 extend substantially along the same axis in the first direction X; the atomizing core 3 is provided on the bracket 2 and is located between the air flow channel 22 and the liquid storage chamber 21, the atomizing core 3 is provided with an atomizing surface 31 for generating an aerosol, and the atomizing surface 31 is parallel to the first direction X. Compared with the conventional method in which the extension direction of the airflow channel 22 is perpendicular to the atomizing surface 31 of the atomizing core 3, the above method can make the extension direction of the airflow channel 22 parallel to the atomizing surface 31 of the atomizing core 3, that is, the flow direction of the airflow is parallel to the atomizing surface 31, thereby reducing the obstruction to the output of the aerosol flowing through the airflow channel 22, thereby reducing the generation and accumulation of condensate, and improving the taste of the aerosol flowing through the airflow channel 22.

[0039] For the above-mentioned aerosol generating device 100, please refer to Figure 3 The housing 1 further includes an air inlet 12 connected to an air flow channel 22. Along the first direction X, the air flow channel 22 is offset from the air inlet 12, that is, the air flow channel 22 is not in a straight line with the air inlet 12, and the air flow channel 22 is in a straight line with the air outlet 11.

[0040] In some embodiments, see Figure 2 and Figure 3 , the atomizing surface 31 is flush with the inner wall of the airflow channel 22. Through the above-mentioned method, it is possible to prevent the atomizing core 3 from protruding from the inner wall of the airflow channel 22 and extending into the airflow channel 22 along the inner wall of the airflow channel 22 toward the center, thereby reducing the obstruction of the atomizing core 3 to the flow of the airflow. In addition, through the above-mentioned method, when condensate is formed at the airflow near the air outlet 11, the formed condensate can be returned to the atomizing surface 31 along the inner wall of the airflow channel 22 for secondary atomization, which is conducive to reducing the accumulation of condensate. It is understandable that in some other embodiments, the atomizing surface 31 is not flush with the inner wall of the airflow channel 22, for example: the atomizing surface 31 is recessed in the inner wall of the airflow channel 22 along the inner wall of the airflow channel 22 toward the center, thereby preventing the atomizing core 3 from protruding from the inner wall of the airflow channel 22 and extending into the airflow channel 22 along the inner wall of the airflow channel 22 toward the center.

[0041] For the above-mentioned air flow channel 22, see Figure 1 and Figure 2 In some embodiments, the airflow channel 22 includes a first airflow channel 221 and a second airflow channel 222 located on the same axis and in a straight line, the air outlet 11 is located at one end of the first airflow channel 221, and the other end of the first airflow channel 221 is connected to the second airflow channel 222. Along the first direction X, the cross-sectional area of ​​the first airflow channel 221 is smaller than the cross-sectional area of ​​the second airflow channel 222, and the atomizer core 3 is located between the second airflow channel 222 and the liquid storage chamber 21. In the above manner, the airflow channel 22 forms a structure that is narrow at the top and wide at the bottom, wherein the atomizer core 3 is located at the lower part of the airflow channel 3, and the structure that is narrow at the top and wide at the bottom can adapt to the width of the atomizer core 3, thereby making the atomization surface 31 of the atomizer core 3 completely exposed to the airflow channel 22, which helps the aerosol generated by the atomization surface 31 to completely enter the airflow channel 22.

[0042] For the first air passage 221 and the second air passage 222, in order to reduce the resistance of the air flowing through the air passage 22, please refer to Figure 1 and Figure 2In some embodiments, the support 2 includes a first inclined surface 223 for defining at least part of the airflow channel 22. The first inclined surface 223 is located at the connection between the first airway 221 and the second airway 222. The first inclined surface 223 is used to guide the airflow from the second airway 222 into the first airway 221. The first airway 221 and the second airway 222 form a structure of the airflow channel 22 that is narrow at the top and wide at the bottom. In the process of gas flowing from the second airway 222 to the first airway 221, the first inclined surface 223 can improve the smoothness of gas flowing from the second airway 222 to the first airway 221.

[0043] For the above-mentioned aerosol generating device 100, please refer to Figures 2 to 4 In some embodiments, the bracket 2 is further provided with a first installation cavity 27 , the first installation cavity 27 is located between the liquid storage cavity 21 and the air flow channel 22 , the first installation cavity 27 connects the liquid storage cavity 21 and the air flow channel 22 , and the atomizer core 3 is installed in the first installation cavity 27 .

[0044] Considering that the first installation cavity 27 is connected to the liquid storage cavity 21 and the air flow channel 22, in order to improve the sealing between the first installation cavity 27 and the atomizer core 3, please refer to Figure 3 and Figure 5 In some embodiments, the aerosol generating device 100 further includes a first seal 4, which is disposed between the side wall of the first mounting cavity 27 and the side wall of the atomizer core 3. The first seal 4 can improve the sealing between the side wall of the first mounting cavity 27 and the side wall of the atomizer core 3, and prevent the liquid matrix in the liquid storage cavity 21 from leaking from between the side wall of the first mounting cavity 27 and the side wall of the atomizer core 3.

[0045] For the above-mentioned aerosol generating device 100, when the liquid matrix in the liquid storage chamber 21 is generating aerosol, the liquid matrix is ​​reduced accordingly and causes the air pressure of the liquid storage chamber 21 to be unbalanced. In order to balance the air pressure of the liquid storage chamber 21, please refer to Figures 3 to 5 The bracket 2 is also provided with an air supply channel 23 , and the air supply channel 23 is located between the side wall of the first installation cavity 27 and the side wall of the first sealing member 4 .

[0046] For the above-mentioned air supply channel 23, please refer to Figures 3 to 5 The bracket 2 includes a liquid outlet 215, which is connected to the first installation cavity 27 and the liquid storage cavity 21. The port of the air supply channel 23 connected to the liquid storage cavity 21 is staggered with the liquid outlet 215. The liquid outlet 215 is used to output the liquid matrix stored in the liquid storage cavity 21 to the atomizer core 3. The atomizer core 3 receives the liquid matrix from the liquid outlet 215 and is heated by the atomization surface 31 of the atomizer core 3 to generate an aerosol. The air supply channel 23 has a capillary effect, which can circulate gas and prevent leakage of the liquid matrix. When the liquid matrix is ​​reduced and the air pressure in the liquid storage cavity 21 is unbalanced, the air supply channel 23 can be used to timely supply air to the liquid storage cavity 21 to balance the air pressure.

[0047] When condensate is formed near the air outlet 11, and the formed condensate flows back to the atomization surface 31 along the inner wall of the air flow channel 22 for secondary atomization, only a part of the condensate can flow back to the atomization surface 31 for secondary atomization, while the other part of the condensate flows back to the bottom of the air flow channel 22 along the inner wall of the air flow channel 22. Therefore, in order to reduce the accumulation of condensate in the air flow channel 22 and the mixing with the aerosol generated by heating, which affects the inhalation taste, please refer to Figure 3 and Figure 4 In some embodiments, the bracket 2 is further provided with a collecting chamber 28. Along the first direction X, the collecting chamber 28 is located on a side of the first installation chamber 27 away from the air outlet 11. The collecting chamber 28 is used to collect the condensed liquid matrix.

[0048] In order to timely feedback the gas flow status of the gas flow channel 22, please refer to Figure 3 and Figure 4 In some embodiments, an airflow sensor 210 is further included. The bracket 2 is further provided with a second installation cavity 29 on a side away from the collecting cavity 28 . The second installation cavity 29 is connected to the airflow channel 22 , and the airflow sensor 210 is installed in the second installation cavity 29 .

[0049] In order to improve the accuracy of the air flow sensor in detecting the air flow state of the air flow channel 22 and prevent the condensate from entering the second installation cavity 29 during the process of the condensate flowing back to the collection cavity 28, please refer to Figure 3 and Figure 4 In some embodiments, the bracket 2 is further provided with an airflow detection channel 211 , which connects the airflow channel 22 and the airflow sensor 210 , and the tube body of the airflow detection channel 211 extends into the collecting chamber 28 .

[0050] For the above liquid storage chamber 21, in order to facilitate the injection of liquid matrix into the liquid storage chamber 21, please refer to Figure 5 and Figure 6 , further comprising an upper cover 5, the bracket 2 is further provided with a liquid injection hole 24, the liquid injection hole 24 and the liquid storage chamber 21 are in liquid conduction, and the upper cover 5 is covered on the liquid injection hole 24. It can be understood that the upper cover 5 includes but is not limited to being fixed to the bracket 2 by one or more connection methods such as snap connection, thread connection, clamp connection, adhesive connection or magnetic connection, so that the upper cover 5 is covered on the liquid injection hole 24.

[0051] To facilitate the quick connection between the upper cover 5 and the bracket 2, please refer to Figure 5 and Figure 6 In some embodiments, the upper cover 5 is provided with a positioning groove 51 , and the bracket 2 is provided with a positioning protrusion 25 , and the positioning groove 51 is connected and matched with the positioning protrusion 25 , so that the upper cover 5 is covered on the injection hole 24 .

[0052] For the upper cover 5, in order to enhance the sealing between the upper cover 5 and the liquid injection hole 24 and reduce liquid leakage, please refer to Figure 5 and Figure 6 The aerosol generating device 100 further includes a second sealing member 6 , which is disposed between the liquid injection hole 24 and the upper cover 5 .

[0053] In some embodiments, see Figure 5 The upper cover 5 is provided with a protrusion 52, which at least partially extends into the injection hole 24, and the second sealing member 6 is sleeved on the protrusion 52. The second sealing member 6 follows the protrusion 52 and extends into the injection hole 24, and the outer wall of the sealing member abuts against the inner wall of the injection hole 24 to form a seal.

[0054] See also Figure 5 and Figure 6 In some embodiments, the liquid storage chamber includes a first liquid storage chamber 212 and a second liquid storage chamber 213, the injection hole 24 is connected to one end of the first liquid storage chamber 212, and the other end of the first liquid storage chamber 212 is connected to the second liquid storage chamber 213. Along the first direction, the cross-sectional area of ​​the first liquid storage chamber 212 is greater than the cross-sectional area of ​​the second liquid storage chamber 213, and the atomizer core 3 is located between the air flow channel 22 and the second liquid storage chamber 213. In the above manner, the liquid storage chamber 21 forms a structure that is wide at the top and narrow at the bottom, which can facilitate liquid inlet.

[0055] In order to facilitate the flow of the liquid matrix in the first liquid storage chamber 212 to the second liquid storage chamber 213 and reduce the residual liquid matrix in the first liquid storage chamber 212, please refer to Figure 5 and Figure 6 In some embodiments, the bracket 2 further includes a second inclined surface 214, which is located at the connection point between the first liquid storage chamber 212 and the second liquid storage chamber 213, and is used for guiding liquid.

[0056] For the above-mentioned aerosol generating device 100, please refer to Figure 5 The aerosol generating device 100 further includes a circuit board 7 and an electrode needle 8.

The two ends of the electrode needle 8 are correspondingly connected to the atomizing core 3 and the circuit board 7. In the above manner, the two electrodes of the atomizing core 3 can be directly connected to the circuit board 7, avoiding the large resistance or easy disconnection caused by the indirect connection between the electrodes of the atomizing core 3 and the circuit board 7, thereby improving the connection reliability and the efficiency of circuit transmission.

[0057] See also Figure 7In some embodiments, the electrode needle 8 includes an L-shaped first portion 81 and a second portion 82, the first portion 81 abuts against the atomizing surface 31 to keep the atomizing core 3 on the bracket 2, and the second portion 82 passes through the bracket 2 and is connected to the circuit board 7. In the above manner, the electrode needle 8 forms an L-shaped structure, that is, the electrical connection between the atomizing core 3 and the circuit board 7 can be achieved through the first portion 81, and the cooperation of the first portion 81 and the second portion 82 can play a role in pressing and fixing the atomizing core 3, which helps to improve the stability of the atomizing core 3.

[0058] In some embodiments, the cross-sections of the first part 81 and the second part 82 are both rectangular. In the above manner, the first part 81 and the second part 82 are both rectangular columnar structures. Compared with a circular columnar structure whose side abuts the atomizer core only in line contact, when the first part 81 and the second part 82 are both rectangular columnar structures, their rectangular side abuts the atomizer core 3 and is in surface contact, which can increase the contact area, thereby improving the stability of the atomizer core 3 and the stability of the electrical connection.
