Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an aerosol generating device. Background Technology

[0002] An aerosol generator is a device that heats an aerosol-forming matrix to generate aerosols for users to inhale. The aerosol generator heats and atomizes the aerosol-forming matrix located within a heating chamber to form an aerosol that can be inhaled by the user.

[0003] In related technologies, the filaments within the aerosol forming matrix are typically arranged vertically in a strip-like pattern. This arrangement causes the airflow to primarily flow along the vertical direction of the aerosol forming matrix during suction, making lateral diffusion difficult. Furthermore, the airflow through the device's intake structure is concentrated in the central region of the aerosol forming matrix, failing to effectively extract aerosols from the outer ring of the matrix. This results in two consequences: firstly, a smaller amount of aerosol being drawn during suction; and secondly, aerosols accumulating around the periphery of the aerosol forming matrix, wetting it. Utility Model Content

[0041] Example:

[0042] Please see Figures 1 to 5This utility model provides an aerosol generating device, including a shell 1, a hollow body 2, and a baffle 3. The shell 1 is provided with an air inlet channel 11; the hollow body 2 is disposed on the shell 1 and has a heating cavity 21 extending through its top and bottom ends, the heating cavity 21 being used to contain an aerosol forming matrix 9; the baffle 3 is disposed on the shell 1 with its top end close to the bottom end of the hollow body 2, and the baffle 3 is provided with a first air passage 321, a guide hole 322, and a circumferential... Multiple air inlets 34 are spaced apart and located at the top end face of the baffle 3. The first air passage 321 is connected to the guide hole 322 and the heating chamber 21 respectively. The guide hole 322 is connected to the air intake channel 11. The air inlets 34 are connected to the first air passage 321 and the heating chamber 21 respectively. The first air passage 321 and the heating chamber 21 are coaxially arranged. When the aerosol forming matrix 9 is inserted into the heating chamber 21, the top end of the baffle 3 supports the aerosol forming matrix 9.

[0043] During suction, external gas flows into the first air passage 321 through the air inlet channel 11 and the guide hole 322. Part of the gas in the first air passage 321 flows directly into the central area of ​​the aerosol forming matrix 9 and drives the aerosol in the central area to flow out. Another part of the gas flows into the outer side of the aerosol forming matrix 9 through the air inlet 34 and drives the aerosol in the outer peripheral area to flow out. This can effectively suction out all the generated aerosol, increase the amount of aerosol during suction, and effectively prevent the aerosol on the outer periphery of the aerosol forming matrix from wetting the aerosol forming matrix 9, thus improving the user experience.

[0044] It should be noted that, since the top of the aerosol forming matrix 9 supports the aerosol forming matrix 9 when the aerosol forming matrix 9 is inserted into the heating chamber 21, the diameter of the first air passage chamber 321 is smaller than the diameter of the aerosol forming matrix 9, and the outer diameter of the top of the aerosol forming matrix 3 is smaller than or equal to the diameter of the aerosol forming matrix 9.

[0045] In some embodiments, the hollow body 2 can be any of the following: resistance heating, air heating, infrared heating, microwave heating, and electromagnetic induction heating. For example, when the hollow body 2 is resistance heating, the hollow body 2 can be a heating element.

[0046] Please see Figure 4 and Figure 5 ( Figure 5(The arrow in the image points to the length extension direction of the guide hole 322). In some embodiments, the baffle 3 is provided with multiple guide holes 322 arranged circumferentially at intervals. The first air passage chamber 321 is columnar, and the angle between the length extension direction of the guide hole 322 and the circumferential tangent direction of the first air passage chamber 321 is an acute angle. Thus, when the gas flows from the guide hole 322 into the first air passage chamber 321, it rotates at a certain angle. Therefore, during suction, the bottom airflow of the aerosol forming matrix 9 forms a certain orderly rotating flow under the action of the guide hole 322, making the air intake at the bottom of the aerosol forming matrix 9 more uniform and more conducive to the release of aerosol.

[0047] Please see Figure 4 In some embodiments, at least three guide holes 322 are provided, and each guide hole 322 is equally spaced along the circumference. In this way, the air intake uniformity at the bottom of the aerosol forming matrix 9 can be further improved, and a better turbulence effect on the airflow can be achieved.

[0048] Depending on actual needs, the angle between the length extension direction of the guide hole 322 and the circumferential tangent direction of the first air passage 321 can be 5°, 15°, 23°, 30°, etc., and the number of guide holes 322 can be three, four, five, etc.

[0049] It should be understood that, according to the principles of fluid mechanics, when multiple streams of air enter a cylindrical cavity simultaneously and uniformly in a circular direction, a symmetrical and orderly rotating flow will be formed inside the cavity, and the airflow inside the cavity will be relatively uniform.

[0050] In some embodiments, the number of guide holes 322 may also be two.

[0051] In some embodiments, the ratio of the length to the diameter of the first air passage 321 ranges from 1 to 1.6, for example, 1, 1.2, 1.4, 1.6, etc. This allows the rotating airflow within the first air passage 321 to be a spiral laminar flow, resulting in better suction. Furthermore, when space permits, the greater the length of the first air passage 321, i.e., the larger the ratio of its length to its diameter, the better the suction effect.

[0052] Please see Figure 2 , Figure 3 and Figure 4 ( Figure 2(The arrows in the diagram indicate the direction of gas flow). In some embodiments, the baffle 3 includes a mounting portion 31, a baffle portion 32, and a support portion 33. The mounting portion 31 is disposed on the outer casing 1; the baffle portion 32 is disposed on the mounting portion 31, a first air passage chamber 321 is disposed within the baffle portion 32, and guide holes 322 are disposed on the periphery of the baffle portion 32; the support portion 33 is disposed at the end of the baffle portion 32 away from the mounting portion 31, and multiple support portions 33 are provided, which are distributed circumferentially at intervals, and an air inlet notch 34 is provided between adjacent support portions 33. Thus, multiple guide holes 322 are distributed equidistantly on the periphery of the baffle portion 32, ensuring the baffle effect of the baffle 3; multiple air inlet notches 34 are distributed equidistantly on the baffle portion 32, ensuring that the gas in the first air passage chamber 321 can flow out in two parts.

[0053] Please see Figure 4 In some embodiments, both the mounting portion 31 and the turbulence-disrupting portion 32 can be columnar, and the outer diameter of the turbulence-disrupting portion 32 is larger than the outer diameter of the mounting portion 31. The turbulence-disrupting hole can be a stepped hole, thereby facilitating the processing and forming of the turbulence-disrupting hole. The support portion 33 can be block-shaped, and the mounting portion 31, the turbulence-disrupting portion 32, and the support portion 33 can be integrally set, reducing the manufacturing difficulty of the turbulence-disrupting component 3.

[0054] Please see Figure 2 In some embodiments, the end of the support portion 33 away from the turbulence portion 32 is flush with the bottom end of the hollow body 2. In this way, the bottom end of the aerosol forming matrix 9 can be prevented from extending beyond the bottom end of the hollow body 2, that is, the bottom end of the aerosol forming matrix 9 extends beyond the heating chamber 21, thus ensuring the utilization rate of the aerosol forming matrix 9.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the support portion 33 is provided with a guide slope 331 on the side near the first air passage 321, and the guide slope 331 is inclined from the bottom end of the baffle 3 to the top end of the baffle 3. In this way, the uniformity of the airflow flowing into the central region of the aerosol forming matrix 9 from the first air passage 321 can be improved.

[0056] Please see Figure 1 and Figure 2 In some embodiments, the mounting part 31 is provided with mounting holes 311 extending through both ends, and the mounting holes 311 communicate with the first air passage chamber 321; the aerosol generating device also includes a locking member 4, which is fitted into the mounting holes 311 and connected to the outer casing 1. In this way, the deflector 3 can be locked onto the outer casing 1 by the locking member 4, which facilitates the installation of the deflector 3; wherein, the locking member 4 can be a screw, so that the deflector 3 is detachably connected to the outer casing 1, which facilitates the disassembly and replacement of the deflector 3.

[0057] Please see Figure 1 and Figure 2In some embodiments, the aerosol generating device further includes a first support 5 and a second support 6. The first support 5 is disposed on the outer shell 1, and the top end of the hollow body 2 is connected to the first support 5. The outer shell 1 and the first support 5 together form a positioning cavity 51. One end of the positioning cavity 51 penetrates one end face of the outer shell 1, and the other end communicates with the heating cavity 21. The positioning cavity 51 and the heating cavity 21 are coaxially arranged. The second support 6 is disposed on the outer shell 1, and the bottom end of the hollow body 2 is connected to the second support 6. The baffle 3 is disposed on the second support 6. The second support 6 has a second air passage cavity 61 that communicates with the guide hole 322 and the air inlet channel 11 respectively. In this way, the hollow body 2 can be fixed on the outer shell 1 by the first support 5 and the second support 6, simplifying the installation difficulty of the hollow body 2. The aerosol forming matrix 9 is inserted into the heating cavity 21 through the positioning cavity 51, which can guide the insertion of the aerosol forming medium and support the aerosol forming matrix 9 through the first support 5. Moreover, the space of the second air passage 61 is larger than that of the first air passage 321, which can create a pressure difference, making it easier for the gas in the second air passage 61 to flow into the first air passage 321 through the turbulence hole.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the bottom end of the spoiler 3 is provided with a positioning hole 312, and the second bracket 6 is provided with a positioning part 62, which is fitted into the positioning hole 312. This facilitates fixing the spoiler 3 to the second bracket 6; wherein, the positioning part 62 may be provided with a connecting hole, and the locking member 4 is connected to the connecting hole, thereby fixing the spoiler 3 to the second bracket 6 by means of the locking member 4.

[0059] Please see Figure 1 In some embodiments, the aerosol generator further includes a battery 7 and a circuit board 8, both of which are fixed to the outer casing 1. The battery 7 is electrically connected to both the circuit board 8 and the hollow body 2, and the circuit board 8 is electrically connected to the hollow body 2. Thus, the heating power of the hollow body 2 can be controlled by the circuit board 8, and power can be supplied to the circuit board 8 and the hollow body 2 by the battery 7.
