Description

Technical Field

[0001] This application relates to the field of heated cigarette technology, and in particular to a smoke generating device. Background Technology

[0002] Heated tobacco products (i.e., heated tobacco sticks and heated tobacco devices) are emerging healthy tobacco products in recent years. Among them, heated tobacco devices that use center heating typically employ a top air intake method. However, the top air intake method causes the airflow to make a sharp 180° turn, which not only increases the airflow resistance but also makes it very easy for condensate to accumulate at the turn, affecting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a smoke generating device to address the technical problems of high gas flow resistance and easy accumulation of condensate at bends in existing smoking products.

[0007] A heater is housed in the receiving groove and connected to the main body, and the heater extends into the heating channel through the second hole.

[0008] In one embodiment, the bottom wall of the receiving groove is located on the main body, the push block abuts against the bottom wall of the receiving groove, and there is a gap between the push block and the bottom wall of the receiving groove to form the first air intake channel.

[0009] In one embodiment, the bottom wall of the receiving groove is provided with a groove, and the projection of the wall of the second hole in the axial direction of the heating channel falls into the groove.

[0010] In one embodiment, the groove sidewall is provided with a first stepped wall, and the push block has a first mating wall adapted to the first stepped wall on the side facing the groove, and the first mating wall abuts against the first stepped wall.

[0011] In one embodiment, the main body is provided with a guide limiting member on the area of ​​the side wall of the receiving groove, and the push block is provided with a mating groove, which is inserted into the guide limiting member along the axial direction of the heating channel.

[0012] In one embodiment, the guide limiting member includes a first connecting plate and a second connecting plate extending axially along the heating channel. The first connecting plate and the second connecting plate are connected and set at an included angle. Both the first connecting plate and the second connecting plate are inserted into the mating groove and are slidably connected to the groove wall of the mating groove.

[0013] In one embodiment, the cover assembly further includes an upper cover, which is connected to the bracket and detachably connected to the main body. When the upper cover is connected to the main body, an installation cavity for accommodating the push block is formed between the upper cover and the main body, and a gap is formed between the upper cover and the bottom wall of the receiving groove to form a second air intake channel.

[0014] In one embodiment, the bracket is detachably connected to the main body, and the bracket includes a first sleeve and a second sleeve that are slidably connected along the axial direction of the heating channel. The second sleeve is sleeved on the first sleeve, the heating channel is disposed inside the first sleeve, and the side wall of the first sleeve has an opening at one end away from the second sleeve.

[0015] In one embodiment, the outer wall of the first sleeve is provided with a protrusion, and the side wall of the second sleeve is provided with a sliding groove along the axial direction of the heating channel. The protrusion is inserted into the sliding groove and is slidably connected to the sliding groove along the axial direction of the heating channel.

[0016] In one embodiment, the end of the slide away from the heater is provided with a first limiting portion, which abuts against the protrusion to restrict the movement of the protrusion relative to the wall of the slide, and the protrusion is configured to be operablely movable to the end of the slide away from the first limiting portion.

[0017] Beneficial effects:

[0018] The flue gas generating device provided in this application includes a main body assembly, a cover assembly, and a heater. The main body assembly has a receiving groove and includes a detachably connected main body part and a push block. When the push block is connected to the main body part, the push block and the main body part enclose the receiving groove, and the gap between the push block and the main body part forms a first air intake channel. The cover assembly includes a bracket, which is inserted into the receiving groove. The bracket has a heating channel. One end of the heating channel communicates with the outside through a first hole for inserting a cigarette holder. The other end of the heating channel communicates with the receiving groove through a second hole. The first air intake channel is located to the side of the second hole in the axial direction of the heating channel. The heater is housed in the receiving groove and connected to the main body part. The heater extends into the heating channel through the second hole. In this application, the push block is detachably connected to the main body. When the push block is connected to the main body, there is a gap between the push block and the main body to form a first air intake channel. Thus, during the suction process, external gas can be drawn into the receiving groove through the first air intake channel. Since the heating channel is connected to the receiving groove through the second hole, the gas in the receiving cavity enters the heating channel through the second hole, thereby carrying away the vapor generated by the thermal decomposition of the cigarette in the heating channel. That is, by setting the first air intake channel to the side of the second hole in this application, the gas mainly undergoes a 90° directional change, rather than the 180° sharp turn of the traditional top air intake. This not only helps to reduce gas flow resistance, but also reduces the probability of condensate formation. Attached Figure Description

[0035] See Figures 1-4 , Figure 1 This is a schematic diagram of a flue gas generating device provided in an embodiment of this application. Figure 2 This is a partial exploded view of a flue gas generating device provided in an embodiment of this application. Figure 3 This is a partial cross-sectional schematic diagram of a flue gas generating device provided in an embodiment of this application. Figure 4This is a schematic diagram of a flue gas generating device provided in an embodiment of this application with the top cover removed. The flue gas generating device provided in an embodiment of this application includes a main body assembly 100, a cover assembly 200, and a heater 300. The main body assembly 100 has a receiving groove 110 and includes a detachably connected main body portion 120 and a push block 130. When the push block 130 is connected to the main body portion 120, the push block 130 and the main body portion 120 surround the receiving groove 110, and the gap between the push block 130 and the main body portion 120 forms a first air intake channel 140. The cover assembly 200 includes a bracket 210, which is inserted into... A heating channel 211 is provided in the receiving groove 110 and the bracket 210 is provided in the bracket. One end of the heating channel 211 is connected to the outside through the first hole 250 for inserting the cigarette stick 400. The other end of the heating channel 211 is connected to the receiving groove 110 through the second hole 260. In the axial direction of the heating channel 211, the first air inlet channel 140 is located to the side of the second hole 260. The heater 300 is housed in the receiving groove 110 and connected to the main body 120. The heater 300 extends into the heating channel 211 through the second hole 260.

[0036] Specifically, in this application, the push block 130 is detachably connected to the main body 120. When the push block 130 is connected to the main body 120, there is a gap between the push block 130 and the main body 120 to form a first air intake channel 140. Thus, during the suction process, external gas can be drawn into the receiving groove 110 through the first air intake channel 140. Since the heating channel 211 is connected to the receiving groove 110 through the second hole 260, the gas in the receiving cavity enters the heating channel 211 through the second hole 260, thereby carrying away the vapor generated by the thermal decomposition of the cigarette 400 in the heating channel 211. That is, in this application, by setting the first air intake channel 140 to the side of the second hole 260, the gas mainly undergoes a 90° directional change, rather than the traditional 180° sharp turn of top air intake. This not only helps to reduce gas flow resistance, but also reduces the probability of condensate formation.

[0037] The push block 130 is detachably connected to the main body 120, thereby forming a first air intake channel 140 between the push block 130 and the main body 120. This simplifies the manufacturing process. Furthermore, when the push block 130 is detached from the main body, a notch is provided on one side of the receiving groove 110, which facilitates the cleaning of soot generated by the burning of the cigarette 400 in the receiving groove 110, thereby improving the smoke generating device.

[0038] See Figure 2 , Figure 3 and Figure 4In some embodiments, the bottom wall of the receiving groove 110 is located on the main body 120, the push block 130 abuts against the bottom wall of the receiving groove 110, and there is a gap between the push block 130 and the bottom wall of the receiving groove 110 to form a first air intake channel 140.

[0039] Specifically, by providing a first air intake channel 140 between the pusher block 130 and the bottom wall of the receiving tank 110, the flow path of the gas can be shortened, so that the gas entering the bottom of the receiving tank 110 through the first air intake channel 140 can directly enter the heating channel 211 through the second hole 260.

[0040] Furthermore, the bracket 210 extends into the bottom of the receiving groove 110 to increase the contact area between the cigarette stick 400 and the heater 300.

[0041] See Figure 3 and Figure 5 , Figure 5 This is a schematic diagram of a flue gas generating device provided in one embodiment of this application with the top cover and pusher removed. In some embodiments, a groove 111 is provided on the bottom wall of the receiving groove 110. In the axial direction of the heating channel 211, the projection of the hole wall of the second hole 260 falls into the groove 111, so that the soot falling through the second hole 260 can fall into the groove 111, which can prevent it from scattering everywhere. Therefore, when the pusher 130 is disassembled relative to the main body 120, it is easier to collect the soot and clean the receiving groove 110.

[0042] See Figure 3 , Figure 4 and Figure 6 , Figure 6 This is a schematic diagram illustrating the interaction between the heater and the main body in a flue gas generating device according to an embodiment of this application. In some embodiments, a first stepped wall 112 is provided on the side wall of the groove 111, and the push block 130 has a first mating wall adapted to the first stepped wall 112 on the side facing the groove 111. The first mating wall abuts against the first stepped wall 112, thereby limiting the push block 130 and preventing it from shifting relative to the main body 120. In addition, the mating arrangement of the push block 130 and the first stepped wall 112 on the side wall of the groove 111 can shield the soot in the groove 111, thereby stably concentrating the soot in the groove 111.

[0043] Furthermore, the first step wall 112 is arranged circumferentially around the heating channel 211, and is not arranged in a full circumference, thereby improving the limiting effect on the push block 130.

[0044] In some embodiments, the outer side of the bottom wall of the receiving groove 110 is provided with a second stepped wall 113, and the push block 130 has a second mating wall adapted to the second stepped wall 113 on the side facing the groove 111. The second mating wall abuts against the second stepped wall 113 to improve the limiting effect on the push block 130.

[0045] See Figure 5 and Figure 7 , Figure 7 This is a schematic diagram of a pusher block in a flue gas generating device according to an embodiment of this application. In some embodiments, the main body 120 is provided with a guide limiting member 150 on the side wall of the receiving groove 110, and the pusher block 130 is provided with a mating groove 131. The mating groove 131 and the guide limiting member 150 are inserted and mated along the axial direction of the heating channel 211, thereby guiding the pusher block 130 relative to the main body 120 during installation. At the same time, it can also limit the movement of the pusher block 130 relative to the main body 120 in a direction perpendicular to the axial direction of the heating channel 211, so as to improve the stability of the connection between the pusher block 130 and the main body 120.

[0046] See Figure 5 , Figure 6 and Figure 7 In some embodiments, the guide limiting member 150 includes a first connecting plate 151 and a second connecting plate 152 extending along the axial direction of the heating channel 211. The first connecting plate 151 and the second connecting plate 152 are connected and set at an angle. The first connecting plate 151 and the second connecting plate 152 are both inserted into the mating groove 131 and are slidably connected to the groove wall of the mating groove 131. Thus, when the push block 130 is connected to the main body 120, the first connecting plate 151 and the second connecting plate 152 set at an angle can stably restrict the push block 130 from moving in two directions perpendicular to the axial direction of the heating channel 211, thereby improving the stability of the connection between the push block 130 and the main body 120.

[0047] Furthermore, there are two guide limiters 150, which are respectively disposed at both ends of the main body 120, thereby further stably guiding and limiting the push block 130.

[0048] See Figure 1 , Figure 3 and Figure 8 , Figure 8This is a schematic diagram of a cover assembly in a flue gas generating device according to an embodiment of this application. In some embodiments, the cover assembly 200 further includes an upper cover 220, which is connected to a bracket 210 and detachably connected to a main body 120. When the upper cover 220 is connected to the main body 120, a mounting cavity 240 for accommodating a pusher block 130 is formed between the upper cover 220 and the main body 120, and there is a gap between the upper cover 220 and the bottom wall of the receiving groove 110 to form a second air intake channel 230.

[0049] Specifically, when the upper cover 220 is connected to the main body 120, a mounting cavity 240 for accommodating the push block 130 is formed between the upper cover 220 and the main body 120, thereby protecting the push block 130. A second air intake channel 230 is formed by a gap between the upper cover 220 and the bottom wall of the receiving groove 110, facilitating the entry of external gas into the first air intake channel 140 via the second air intake channel 230. Since the second air intake channel 230 is located in the gap between the upper cover 220 and the bottom wall of the receiving groove 110, the manufacturing process is simplified, and the gas flow path is shortened to reduce air resistance.

[0050] Furthermore, the upper cover 220 and the push block 130 are located on the same side of the main body 120, which facilitates the disassembly of the push block 130 relative to the main body 120 when the upper cover 220 is disassembled relative to the main body 120, and can shorten the path of gas entering the heating channel 211.

[0051] See Figure 2 , Figure 3 and Figure 8 In some embodiments, the bracket 210 is detachably connected to the main body 120. The bracket 210 includes a first sleeve 212 and a second sleeve 213 that are slidably connected along the axial direction of the heating channel 211. The second sleeve 213 is sleeved on the first sleeve 212. The heating channel 211 is disposed inside the first sleeve 212, and the side wall of the first sleeve 212 away from the second sleeve 213 has an opening 217.

[0052] Specifically, when the bracket 210 is disassembled relative to the main body 120, the first sleeve 212 can slide away from the second sleeve 213 along the axial direction of the heating channel 211, so that the opening 217 on the side wall of the first sleeve 212 is located outside the second sleeve 213. Thus, when the cigarette 400 is broken, the broken cigarette 400 can be taken out through the opening 217, improving the convenience of the smoke generating device.

[0053] It should be noted that since the bracket 210 extends into the bottom of the receiving groove 110, when the bracket 210 is connected to the main body 120, the bottom wall of the receiving groove 110 will play a limiting role to restrict the first sleeve 212 from moving away from the second sleeve 213.

[0054] See Figure 8 In some embodiments, the outer wall of the first sleeve 212 is provided with a protrusion 214, and the side wall of the second sleeve 213 is provided with a sliding groove 215 along the axial direction of the heating channel 211. The protrusion 214 is inserted into the sliding groove 215 and is slidably connected with the sliding groove 215 along the axial direction of the heating channel 211, thereby guiding the relative sliding of the first sleeve 212 and the second sleeve 213.

[0055] See Figure 8 In some embodiments, a first limiting part 216 is provided at the end of the slide 215 away from the heater 300. The first limiting part 216 is used to abut against the protrusion 214 to restrict the movement of the protrusion 214 relative to the groove wall of the slide 215, and the protrusion 214 is configured to be operable to move to the end of the slide 215 away from the first limiting part 216.

[0056] Specifically, the first limiting part 216 abuts against the protrusion 214 to restrict the movement of the protrusion 214 relative to the groove wall of the slide 215, thereby limiting the position of the first sleeve 212 relative to the second sleeve 213, so that the bracket 210 is stably installed in the receiving groove 110. When the bracket 210 is detached from the main body 120, the cigarette 400 in the heating channel 211 can be manually pushed to apply a force away from the second sleeve 213 to the first sleeve 212, causing the first sleeve 212 to slide away from the second sleeve 213. Optionally, the groove wall of the slide 215 is provided with a protrusion, which is constructed as the first limiting part 216.

[0057] Furthermore, each end of the slide groove 215 is provided with a second limiting part 218, which is used to abut against the protrusion 214 to prevent the protrusion 214 from dislodging from the slide groove 215. Optionally, the sidewalls of the two ends of the slide groove 215 are constructed as the second limiting part 218. The bottom wall of the slide groove 215 is provided through, thereby facilitating the engagement with the protrusion 214.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
