[0037] See also Figure 1 , Figure 1 This is a partial structural diagram of an aerosol generating device according to an embodiment of the present application. Figure 1 As shown, an embodiment of the present application discloses an aerosol generating device, which includes a heating cup 100 and a nozzle assembly.

[0038] For details, please refer to Figure 1The heating cup 100 has a heating chamber 110 with an open end; the nozzle assembly is covered at the open end of the heating chamber 110, and the nozzle assembly is provided with an air inlet and an air outlet 221. The air inlet includes a first longitudinal air channel 320 and a transverse air channel 330. One end of the first longitudinal air channel 320 is connected to the outside, and the other end of the first longitudinal air channel 320 is a closed end. One end of the transverse air channel 330 is connected to the heating chamber 110, and the other end of the transverse air channel 330 has a connecting port connected to the first longitudinal air channel 320. The connecting port is higher in the longitudinal direction than the closed end. One end of the air outlet 221 is connected to the heating chamber 110, and the other end of the air outlet 221 is connected to the outside.

[0039] In this embodiment of the present application, the aerosol generating device further includes a heating element 500, which is mounted on the heating cup 100. Specifically, the heating chamber 110 is used to house the aerosol-forming substrate, and the heating element 500 generates the aerosol by heating the heating element 500 within the heating chamber. When a user uses the aerosol generating device, external air flows into the heating chamber 110 through the air inlet, mixes with the generated aerosol, and then flows out through the air outlet.

[0040] In the embodiment of the present application, the connecting port of the transverse air duct 330 is higher in the longitudinal direction than the closed end of the first longitudinal air duct 320. That is, a liquid storage space is formed between the connecting port and the closed end, so that the condensate formed when the aerosol in the inlet duct converges can be stored in the liquid storage space, effectively reducing the problem of condensate blocking the transverse air duct 330.

[0041] In the examples of this application, see Figure 1 The aerosol generating device further includes a capillary structure 600, which is disposed at the bottom of the heating cup 100. In actual use, the aerosol-forming substrate is placed on the capillary structure 600, which is provided with a capillary groove 610. The capillary groove 610 is used to guide the liquid aerosol-forming substrate to the heating area of ​​the heating element 500 to ensure a stable supply of the aerosol-forming substrate, thereby improving the uniformity of atomization and smoke output.

[0042] In some embodiments of this application, see Figures 1 to 3 ,in, Figure 2 This is an exploded schematic diagram of a partial structure of an aerosol generating device according to an embodiment of the present application. Figure 3 for Figure 2Schematic diagram of the exploded structure from another perspective. As shown in the figure, the nozzle assembly also includes a nozzle cover 210 and a seal 300. The nozzle cover 210 is installed on the seal 300, and the seal 300 is installed at the open end. The air outlet 221 is at least partially formed on the nozzle cover 210, and the first longitudinal air channel 320 and the transverse air channel 330 are formed on the seal 300. Specifically, the seal 300 is partially embedded in the heating chamber 110 of the heating cup 100, and the seal 300 is sealed with the heating cup 100; the nozzle cover 210 is installed at the open end of the heating cup 100, the nozzle cover 210 abuts against the seal 300, and the seal 300 is located between the heating cup 100 and the nozzle cover 210. The nozzle cover 210 is provided with a nozzle 220 , and an air outlet 221 communicating with the heating chamber 110 is provided in the nozzle 220 . The air outlet 211 passes through the nozzle cover 210 to form the nozzle 220 communicating with the outside.

[0043] In the above embodiment, the sealing member 300 is provided with a communication channel, which is used to connect the air outlet 221 and the heating chamber 110. It should be noted that Figure 1 and Figure 2 In the figure, the X direction refers to the longitudinal direction, and the Y direction refers to the transverse direction.

[0044] It is worth understanding that the first longitudinal air channel 320 can be a vertical air channel extending along the longitudinal direction of the heating cup 100 (that is, the longitudinal air channel can be parallel to the longitudinal axis of the heating cup 100), or it can be a longitudinal extension with a certain deflection angle relative to the longitudinal line of the heating cup 100, and the deflection angle can be within 10°, within 5° or less; similarly, the transverse air channel 330 can be a horizontal air channel extending horizontally parallel to the bottom of the heating cup 100, or it can be deflected upward or downward at a certain angle relative to the horizontal plane, and the deflection angle can be within 10°, within 5° or even less.

[0045] Further, see Figure 1 The suction nozzle 220 is at least partially embedded in the communication channel of the sealing member 300 to achieve the purpose of positioning and fixing the suction nozzle cover 210.

[0046] In some embodiments of this application, see Figures 1 to 4 As shown, the nozzle cover 210 is provided with an air inlet 211 , a connecting cavity is enclosed between the nozzle cover 210 and the sealing member 300 , an oil suction member 400 is provided in the connecting cavity, and the first longitudinal air channel 320 is connected to the air inlet 211 through the connecting cavity.

[0047] In a possible embodiment, the oil absorbing member 400 is made of oil absorbing cotton. Since the oil absorbing cotton has a porous structure and is air permeable, the first longitudinal air channel 320 can be directly connected to the air inlet 211 through the oil absorbing cotton.

[0048] It is worth noting that, in some other embodiments, the first longitudinal air channel 320 may also be connected to the air inlet 211 through a connection gap formed between the oil suction member 400 , the suction nozzle cover 210 and the sealing member 300 .

[0049] In some embodiments of this application, see Figures 1 to 4 As shown, Figure 4 The following is a schematic diagram of the structure of the nozzle cover 210 in one embodiment. As shown, the nozzle cover 210 is provided with an air inlet 211 and a first groove 212 connected to the air inlet 211. The first groove 212 is formed on the side of the nozzle cover 210 near the sealing member 300. The sealing member 300 is provided with a second groove 310 on the side near the nozzle cover 210. The nozzle assembly also includes an oil suction member 400, which is disposed between the nozzle cover 210 and the sealing member 300.

[0050] The second groove 310 may be provided corresponding to the first groove 212 , or may not be provided corresponding to the first groove 212 , as long as the second groove 310 and the first groove 212 can be communicated.

[0051] Specifically, along the longitudinal direction (i.e., the Y direction), the upper end surface of the oil suction member 400 abuts the lower end of the nozzle cover 210, and the oil suction member 400 and the first groove 212 enclose a first end surface airway. The lower end surface of the oil suction member 400 abuts the upper end surface of the sealing member 300, and the oil suction member 400 and the second groove 310 enclose a second end surface airway. The first end surface airway and the second end surface airway are connected by at least two connecting ports, and the second end surface airway is connected to the first longitudinal airway 320 through the connecting ports. In this embodiment, the first end surface airway and the second end surface airway are connected by at least two connecting ports. If one of the connecting ports is blocked, the other connecting ports can still maintain the connection between the first and second end surface airways, thus avoiding the situation where only one connecting port is blocked and air cannot enter.

[0052] It is worth noting that the connection port between the first end surface air channel and the second end surface air channel can be provided on the oil suction member 400 or outside the oil suction member 400. In addition, the number of connection ports can be set to two, three, or other numbers according to actual needs and is not limited here.

[0053] In some embodiments of this application, see Figure 1As shown, the seal 300 is further provided with a second longitudinal air channel 340, one end of which communicates with the second end surface air channel, and the other end of which communicates with the transverse air channel 330. The second longitudinal air channel 340 can be arranged parallel to the first longitudinal air channel 320, or at a certain angle to the first longitudinal air channel 320. In other words, the second end surface air channel is connected through both the first longitudinal air channel 320 and the second longitudinal air channel 340, preventing the entire air intake duct from being blocked if either the first longitudinal air channel 320 or the second longitudinal air channel 340 is blocked.

[0054] In some embodiments of this application, see Figure 1 and Figure 2 As shown, the first groove 212 and the second groove 310 at least partially extend outside the axially projected coverage area of ​​the oil-absorbing member 400 to form a connection port. In other words, the projections of the first groove 212 and the second groove 310 in the longitudinal direction (Y direction) are at least partially located outside the oil-absorbing member 400. The connection port connecting the first end surface air passage and the second end surface air passage is provided outside the oil-absorbing member 400.

[0055] In some embodiments of this application, see Figure 2 As shown, the second groove 310 includes a third flow channel 311 and a fourth flow channel 312 intersecting the third flow channel 311 . Both the third flow channel 311 and the fourth flow channel 312 partially extend beyond the coverage area of ​​the oil suction member 400 projected in the longitudinal direction to form a connection port.

[0056] In some embodiments of this application, see Figure 3 and Figure 4 As shown, the first groove 212 includes a first flow channel 2121 and a second flow channel 2122 intersecting the first flow channel 2121 . Both the first flow channel 2121 and the second flow channel 2122 at least partially extend outside the coverage area of ​​the oil suction member 400 projected along the longitudinal direction.

[0057] It is worth noting that, in some possible implementations, the first groove 212 may be provided with one flow channel or multiple flow channels. Similarly, the second groove 310 may be provided with one flow channel or multiple flow channels.

[0058] It should be noted that the extension trajectories of the first flow channel 2121 , the second flow channel 2122 , the third flow channel 311 and the fourth flow channel 312 may be straight lines, curves, or other trajectory shapes composed of straight lines and / or curves, which are not limited here.

[0059] In some embodiments of this application, see Figure 2The sealing member 300 is provided with a mounting groove 370, and the oil suction member 400 is mounted in the mounting groove 370. Specifically, the depth of the mounting groove 370 is less than or equal to the thickness of the oil suction member 400, so as to ensure that the two end surfaces of the oil suction member 400 can respectively abut against the suction nozzle cover 210 and the sealing member 300, thereby ensuring that the suction nozzle cover 210, the oil suction member 400, and the sealing member 300 enclose a first end surface air channel and a second end surface air channel.

[0060] In some embodiments of this application, see Figure 1 and Figure 2 Along the longitudinal direction, a liquid blocking portion 360 is provided on at least one of the upper and lower sides of the outer wall of the sealing member 300 corresponding to the connection between the transverse airway 330 and the heating chamber 110. A gap is provided between the liquid blocking portion 360 and the wall of the heating chamber 110. Specifically, the liquid blocking portion 360 protrudes from the outlet end of the transverse airway 330, and the distance between the liquid blocking portion 360 and the inner wall of the heating cup 100 is less than the distance between the outlet end of the transverse airway 330 and the inner wall of the heating cup 100. In this way, the baffle can be used to effectively prevent aerosol from converging and entering the transverse airway 330, thereby reducing the probability of aerosol condensate clogging the transverse airway 330.

[0061] In some embodiments of this application, see Figure 1 As shown, a first liquid storage tank 351 is provided on the side wall of the sealing member 300. The first liquid storage tank 351 is provided above and / or below the opening connecting the transverse airway 330 and the heating chamber 110 (i.e., the opening where the transverse airway 330 passes through the outer wall of the sealing member 300). The first liquid storage tank 351 can store a portion of the aerosol, effectively reducing the possibility of aerosol entering the transverse airway 330 and causing blockage of the transverse airway 330.

[0062] It should be understood that, above the opening where the transverse air channel 330 communicates with the heating chamber 110 refers to the portion of the side wall of the seal 300 in the transverse air channel 330 away from the bottom of the heating cup 100; below the opening where the transverse air channel 330 communicates with the heating chamber 110 refers to the side of the side wall of the seal 300 in the transverse air channel 330 close to the bottom of the heating cup 100.

[0063] As one implementation method, see Figures 1 to 3 As shown, the side wall of the sealing member 300 is provided with one or more first liquid storage grooves 351 above and below the transverse air channel 330 .

[0064] In some embodiments of this application, see Figure 1 and Figure 3As shown, at least one second liquid storage tank 352 is further provided on one side of the sealing member 300 near the bottom of the heating chamber 110. In this way, the second liquid storage tank 352 can be used to further store part of the aerosol, which can effectively reduce the situation where the aerosol flows into the transverse airway 330 and causes blockage of the transverse airway 330.

[0065] In some specific embodiments, the first liquid storage groove 351 and the second liquid storage groove 352 may be capillary grooves.

[0066] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
