Embodiment 1

This embodiment provides an atomization device, which can ensure that the temperature of the outer surface of the circumference is relatively low, reduce the probability of scalding the user, facilitate the user's grip, and have high safety.

As shown in FIG. 1 to FIG. 4 , the atomizing device includes a cylindrical housing 1 and a separator 2 and a heating assembly 3 respectively fixed in the housing 1 .

The housing 1 includes a cylindrical main housing 11 and a head cover 12 and a tail cover 13 respectively connected to the two ends of the main housing 11. In one embodiment, the head cover 12 can be sealed to one end of the main housing 11, and the tail cover 13 can be sealed to the other end of the main housing 11. As shown in FIG. 1 , the tail cover 13 has a first air inlet 131, a second air inlet 132 and an air outlet 133.

In one embodiment, the first air inlet 131, the second air inlet 132 and the air outlet 133 penetrate the tail cover 13 along the axis of the main housing 11. The first air inlet 131 and the second air inlet 132 are used for gas to enter the atomizing device, and the air outlet 133 is used for gas carrying tobacco flavor (i.e., atomized particles) to flow out of the atomizing device. The shape of the main housing 11 can be set according to actual needs. In some embodiments, the main housing 11 is cylindrical.

As shown in FIG5 , the separator 2 is cylindrical and fixed in the main shell 11. A first air channel 10 is formed between the inner wall of the main shell 11 and the outer wall of the separator 2. The first air channel 10 is connected to the first air inlet 131, so that the gas can enter the first air channel 10 through the first air inlet 131. In one embodiment, the axis of the separator 2 coincides with the axis of the main shell 11.

Please continue to refer to FIG. 5 . The heating assembly 3 is fixed in the separator 2 . In some embodiments, the axis of the heating assembly 3 coincides with the axis of the separator 2 .

The second air passage 20 is formed between the outer wall of the heating assembly 3 and the inner wall of the separator 2, and the heating assembly 3 has a middle air passage 30, the second air passage 20 is connected to the second air inlet hole 132, so that the gas can enter the second air passage 20 through the second air inlet hole 132, and the middle air passage 30 is connected to the air outlet hole 133, so that the gas in the atomizing device can pass through the middle air passage 30 and the outlet hole 133. The gas flows out of the air hole 133, and the first air channel 10 and the second air channel 20 are respectively connected to the middle air channel 30, so that the gas in the first air channel 10 and the second air channel 20 can flow into the middle air channel 30. The middle air channel 30 is used to accommodate the part to be atomized 100, so that the gas flowing into the middle air channel 30 can heat the part to be atomized 100, thereby causing the part to be atomized 100 to atomize and generate smoke. In one embodiment, the shape and size of the middle air channel 30 match the shape and size of the part to be atomized 100, so that when the part to be atomized 100 is located in the middle air channel 30, its outer wall is in close contact with the inner wall of the heating assembly 3. In one embodiment, the atomization member 100 may be a structure such as tobacco or a smoke bomb, and the atomization member 100 does not burn after being heated. It should be noted that the atomization member 100 has a portion exposing the middle air passage 30 for the user to put into the mouth.

When the atomizing device provided in this embodiment is used, as shown in FIG. 13 , the atomizing component 100 is inserted into the middle air passage 30, and the switch of the heating assembly 3 is turned on. When the user inhales the end of the atomizing component 100 located outside the middle air passage 30, since the atomizing component 100 is a loose porous medium, a negative pressure is generated in the middle air passage 30. At this time, air enters the first air passage 10 from the first air inlet 131 and enters the second air passage 20 from the second air inlet 132. The gas in the first air passage 10 can carry the heating assembly 3 to the main housing 11. The heat dissipated by the heating component 3 to the main housing 11 can also be taken away by the gas in the second air duct 20, that is, the gas in the first air duct 10 and the gas in the second air duct 20 are heated, and the heated gas in the first air duct 10 and the heated gas in the second air duct 20 both enter the middle air duct 30, preheat or heat the atomization part 100 in the middle air duct 30, and directly heat the atomization part 100 in combination with the heating component 3, so that the atomization part 100 is atomized to form smoke and inhaled into the user's mouth. In FIG. 14 , the thick solid line represents the flow path of the gas entering from the first air inlet 131, and the thick dotted line represents the flow path of the gas entering from the second air inlet 132.

In the atomizing device provided in this embodiment, the first air inlet hole 131 is connected to the first air passage 10, the second air inlet hole 132 is connected to the second air passage 20, and the first air passage 10 and the second air passage 20 are both connected to the middle air passage 30, so that the first air passage 10 and the second air passage 20 are both used for air intake, realizing the parallel air intake of the first air passage 10 and the second air passage 20, and the dual function of the atomizing device. The layered air intake can take away the heat that may be transferred to the main shell 11, and the setting of the separator 2 can also absorb part of the heat, thereby increasing the thermal resistance between the heating component 3 and the main shell 11, so that the heat transferred to the main shell 11 can be less, thereby ensuring that the temperature of the main shell 11 is lower, reducing the probability of scalding the user, facilitating the user's grip, and having higher safety.

In one embodiment, as shown in FIG. 1 and FIG. 2 , a plurality of first air inlet holes 131 are provided, and the plurality of first air inlet holes 131 are distributed at equal angles in a circular matrix around the air outlet hole 133, so that gas can enter the circumference of the heating assembly 3, so as to be able to block the heat transfer to the main shell 11 in the circumference of the heating assembly 3, so that the temperature of each position of the main shell 11 is relatively low, thereby improving the uniformity of the temperature of the main shell 11. In one embodiment, the circular matrix refers to the plurality of first air inlet holes 131 arranged in an array along the circumference of the tail cover 13.

In one embodiment, as shown in FIG2 , a plurality of second air inlet holes 132 are provided, and the plurality of second air inlet holes 132 are closer to the air outlet holes 133 than the plurality of first air inlet holes 131. The plurality of second air inlet holes 132 are distributed at equal angles in a circular matrix around the air outlet holes 133, further improving the uniformity of the temperature of the main housing 11.

In one embodiment, the first air inlet hole 131 and the second air inlet hole 132 are both strip holes or arc holes extending along the circumference of the main housing 11 .

In one embodiment, as shown in FIG8 and FIG9, the separator 2 includes a separator tube 21 and a separator plate 22 fixed to one end of the separator tube 21. In one embodiment, the separator plate 22 can be fixed to one end of the separator tube 21 near the head cover 12. A first air passage 10 is formed between the main housing 11 and the outer wall of the separator tube 21, and a second air passage 20 is formed between the heating assembly 3 and the inner wall of the separator tube 21.

A confluence chamber 40 is formed between the partition plate 22 and the head cover 12. The partition plate 22 has a plurality of fourth through holes 221 connected to the second air channel 20 and a plurality of fifth through holes 222 connected to the middle air channel 30. The first air channel 10 is connected to the confluence chamber 40, the second air channel 20 is connected to the confluence chamber 40 through the fourth through holes 221, and the middle air channel 30 is connected to the confluence chamber 40 through the fifth through holes 222. The gas in the first air channel 10 and the gas in the second air channel 20 both enter the confluence chamber 40 and flow from the confluence chamber 40 into the middle air channel 30. The setting of the confluence chamber 40 allows the gas in the first air channel 10 to be fully mixed with the gas in the second air channel 20 to prevent the temperature of the gas entering the middle air channel 30 from being too low, thereby improving the atomization effect.

In one embodiment, as shown in FIG. 4 or FIG. 7 , the housing 1 further includes a support plate 4 disposed in the confluence cavity 40 and fixedly connected to the inner wall of the main housing 11, the support plate 4 having a plurality of first flow diversion holes 41 connected to the first air channel 10, a plurality of second flow diversion holes 42 connected to the second air channel 20, and a third flow diversion hole 43 connected to the intermediate air channel 30. The plurality of first flow diversion holes 41 are arranged around the third flow diversion hole 43 in a circular matrix at equal angles, and the plurality of second flow diversion holes 42 are arranged around the third flow diversion hole 43 in a circular matrix at equal angles. Furthermore, the plurality of second flow diversion holes 42 correspond to the plurality of fourth through holes 221 one by one, and each second flow diversion hole 42 is opposite to the corresponding fourth through hole 221 in the axial direction of the main housing 11, so that the gas flowing out of the fourth through hole 221 flows to the second flow diversion hole 42, reducing the flow resistance. In one embodiment, the support plate 4 and the main housing 11 are an integrally formed structure to have a higher connection strength.

In one embodiment, as shown in FIG8 , the partition plate 22 has a convex cylinder 223 and a plurality of protrusions 224 on one side facing the support plate 4. In one embodiment, the axis of the convex cylinder 223 can coincide with the axis of the main housing 11. As shown in FIG4 , the convex cylinder 223 extends into the third diversion hole 43 and contacts or connects with the hole wall of the third diversion hole 43. The intermediate air channel 30 is connected with the convex cylinder 223. The mixed gas in the confluence chamber 40 enters the intermediate air channel 30 through the convex cylinder 223 and the fourth through hole 221. The protrusion 224 abuts against the support plate 4, and the other end of the partition tube 21 abuts against the tail cover 13. The partition 2 is fixed in the main housing 11 by the support plate 4 and the tail cover 13 to prevent the partition 2 from moving in the axial direction of the main housing 11.

The first positioning protrusion 23 is placed in the first positioning recess 111 to facilitate the positioning and assembly of the main housing 11 and the separator 2, and also to facilitate the circumferential positioning of the separator 2 by the main housing 11. As shown in FIGS. 6 and 8, the inner wall of the main housing 11 has the first positioning recess 111, and the outer wall of the separator 2 (specifically, the outer wall of the separator tube 21) has the first positioning protrusion 23, which extends from one end of the separator tube 21 to the other end thereof.

In addition, one of the inner wall of the separator 2 and the outer wall of the heating assembly 3 has a second positioning recess 24, and the other has a second positioning protrusion 34. The second positioning protrusion 34 is placed in the second positioning recess 24 to be used for positioning and assembling the separator 2 and the heating assembly 3, and also for the separator 2 to limit the circumferential position of the heating assembly 3.

The atomization device provided in this embodiment has the following beneficial effects:

1) Low air resistance. The tail end has multiple layers of external atmospheric air input channels, namely, multiple first air inlet holes 131 and multiple second air inlet holes 132. Each layer of air channels is distributed at equal angles in a circular matrix, and at the head end, all air flows converge in the confluence cavity 40 and enter the middle air channel 30, and finally the gas generated by the heated non-combustible tobacco or the heated herbs uniformly flows out from the surface of the loose porous layer medium to the negative pressure oral cavity of the consumer;

2) No heat generation on the outer surface. The first air channel 10 and the second air channel 20 form a multi-layer airflow, and the internal multi-layer airflow can completely remove the heat that may be transferred to the main shell 11, which can fully ensure that the outer surface around the main shell 11 is roughly at room temperature;

3) Sufficient heating without burning. The electromagnetic field eddy current generated by the electromagnetic induction coil 32 when it is energized generates a magnetic field-heating effect with the metal core 331 of the induction heater 33. This heating principle can keep the surface temperature of the induction heater 33 basically constant, and the central junction temperature is relatively high. Since the current can be controlled and output very accurately, it ensures that the temperature generated by the magnetic field-heating effect can be finely controlled, and precise temperature control is achieved. In summary, it can be ensured that the surface and center of the heated non-burning tobacco or herbs can obtain basically equivalent heating effects, and the disadvantage of poor central heating can be prevented.

In this embodiment, the separator 2 includes a plurality of coaxially sleeved separation tubes and a separation plate connected to one end of the plurality of separation tubes. The inner diameters of the plurality of separation tubes are different, and a separation air channel can be formed between two adjacent separation tubes. The tail cover 13 also has a third air inlet hole connected to the separation air channel. The separation plate has a hole structure connected to the separation air channel. The separation air channel is connected to the middle air channel 30 through the hole structure. The gas enters the separation air channel through the third air inlet hole, absorbs the heat dissipated by the heating assembly 3 in the separation air channel, flows out from the hole structure, and flows into the middle air channel 30. It should be noted that a confluence cavity can be formed between the partition plate and the head cover 12, and the gas flowing out of the hole structure enters the confluence cavity and mixes with the gas flowing out of the first air channel 10 and the gas flowing out of the second air channel 20, and the mixed gas enters the middle air channel 30. It should be noted that the first air channel 10 is formed between the outer cylinder and the main shell 11, and the second air channel 20 is formed between the inner cylinder and the main shell 11. By providing multiple partition cylinders, at least one partition air channel can be formed, and the gas in the partition air channel can also absorb the heat dissipated by the heating component 3, further reducing the temperature of the main shell 11.
