Description

Technical Field

[0001] This invention relates to a thin smoke machine and a heating unit for a smoke machine. The thin smoke machine is used to emit smoke, and the heating unit for the thin smoke machine is used to heat e-liquid into smoke, which can make the beam effect of the light more obvious. Background Technology

[0002] A type of thin smoke machine is often used in entertainment and performance settings. This type of smoke machine can produce an appropriate amount of smoke and spray it into the space. In addition to creating a smoke-filled effect, the smoke can also be used in conjunction with lighting to make the visual effect of the beams better.

[0003] Most commercially available slim smoke hoods that generate smoke through heating require a pump to deliver e-liquid. In order to control the amount of smoke effectively, the slim smoke hood needs to precisely control the pump's delivery rate. The pump, as well as the electronic equipment and software or firmware that control the pump's operation, will increase the manufacturing cost of such slim smoke hoods. Summary of the Invention

[0004] The purpose of this invention is to provide a thin smoke machine and a heating unit for a thin smoke machine.

[0005] Therefore, the present invention provides a thin smoke hood, comprising:

[0006] A carrier, the carrier including an e-liquid chamber for containing e-liquid;

[0007] A heating unit is installed within the carrier, the heating unit comprising a heater, a conveyor having capillary action, and a heat-conducting box connecting the heater and the conveyor, the heat-conducting box comprising a chamber, the heat-conducting box being separated from the e-liquid;

[0008] A mouthpiece mechanism is connected in communication with the chamber of the heating unit, and the smoke in the chamber is guided out along the mouthpiece mechanism.

[0009] The heat-conducting box of the heating unit is made of a metal material with heat storage effect, which enables the heater to maintain a sufficient operating temperature during operation, thus ensuring that the e-liquid can be heated into smoke. In addition, the chamber of the heating box provides a temporary smoke-containing space, and the smoke in the chamber can move to the mouthpiece mechanism and be ejected along the guide of the mouthpiece mechanism.

[0010] In one embodiment, the thin smoke hood further includes:

[0011] A fan, the mouthpiece mechanism includes a first end, a second end and a third end located outside the carrier, the fan includes an air outlet connected to the first end of the mouthpiece mechanism, the second end of the mouthpiece mechanism is connected in communication with the chamber of the heat conduction box, part of the airflow generated by the operation of the fan enters the chamber of the heating unit from the second end and pushes the smoke located in the chamber into the mouthpiece mechanism from the second end, and another part of the airflow generated by the fan is guided by the mouthpiece mechanism to drive the smoke in the mouthpiece mechanism to be ejected from the third end.

[0012] In one embodiment, the thin smoke hood further includes:

[0013] An inner cover includes a conduit, wherein the mouthpiece mechanism further includes a second end and a third end, the mouthpiece mechanism further includes a first air duct extending inward from the end face of the first end, the mouthpiece mechanism further includes two flues and a second air duct extending inward from the end face of the second end, the second air duct being spaced apart between the two flues and communicating with the first air duct, the two flues being spaced apart from the first air duct, the mouthpiece mechanism further includes a third air duct extending from the third end toward the first air duct and being spaced apart from the second air duct, the third air duct communicating with the first air duct, the two flues communicating with the third air duct, the conduit being communicatively connected between the second end of the mouthpiece mechanism and the chamber, a portion of the airflow from the fan enters the chamber through the first air duct, the second air duct, and the conduit of the mouthpiece mechanism, causing the smoke in the chamber to be pushed and flow along the conduit, the two flues, and the third air duct and ejected from a smoke outlet.

[0014] The design of the mouthpiece mechanism divides the airflow generated by the fan into two non-interfering parts, allowing a single fan to smoothly drive the smoke out of the smoke outlet.

[0015] In one embodiment, the conduit further includes two partitions that separate an air inlet and two exhaust channels within the conduit. The air inlet is located between the two partitions and is separated from the two exhaust channels. The air inlet extends into the chamber, and the two exhaust channels are connected in communication with the chamber.

[0016] The design of the mouthpiece mechanism, in conjunction with the air intake and the two exhaust ducts separated by the duct piece, ensures that the airflow generated by the fan and the smoke generated by the heating unit are free from turbulence, and further allows the smoke to be smoothly ejected from the smoke outlet.

[0017] In one embodiment, the thin smoke hood further includes:

[0018] An e-liquid bottle containing the e-liquid, the e-liquid bottle including a neck and a sealing film sealing an opening included in the neck, wherein when the sealing film remains intact, the e-liquid inside the e-liquid bottle will not enter the carrier;

[0019] A connecting ring is provided. The carrier includes a first cavity and a second cavity. The carrier further includes a connecting pipe connecting the first cavity and the second cavity. The heating unit is housed in the second cavity. The connecting ring is fixed to the first cavity. The connecting ring includes a spike with an opening communicating with the interior of the first cavity. When the e-liquid bottle is attached to the first cavity, the spike pierces the sealing film, allowing the e-liquid in the e-liquid bottle to enter the first cavity through the opening and then enter the second cavity along the connecting pipe.

[0020] The e-liquid bottle is designed to be disposable, and with the connecting ring, the e-liquid bottle can be replaced quickly and without leakage, making the slim e-cigarette device very convenient.

[0021] In one embodiment, the thin smoke hood further includes:

[0022] An inner cover includes a conduit, a carrier includes a first cavity and a second cavity, the carrier further includes a connecting tube connecting the first cavity and the second cavity, the conduit extends into the heating unit, the second cavity further includes an upper end and a lower end, one end of the connecting tube is connected to the lower end and spaced apart from the upper end, the second cavity includes an installation space extending from the end face of the upper end toward the lower end but spaced apart from the lower end, the second cavity further includes an e-liquid chamber, the heating unit is combined with the inner cover, the inner cover is accommodated in the installation space and closes the e-liquid chamber, the heating unit is located in the e-liquid chamber, and the maximum height of the e-liquid in the e-liquid chamber is approximately flush with the uppermost end of the connecting tube;

[0023] An outer cover is fixed to the upper end of the second cavity and closes the mounting space. The outer cover presses against the inner cover to close the e-liquid chamber and covers the chamber. The outer cover is connected in communication with the conduit. The mouthpiece mechanism further includes a second end connected in communication with the outer cover. The smoke enters the mouthpiece mechanism through the conduit and the outer cover.

[0024] The inner cover separates the e-liquid chamber where the e-liquid is stored from the installation space, preventing the e-liquid in the e-liquid chamber from easily leaking out. Furthermore, the connecting ring and the e-liquid bottle are screwed together for a tight seal, thus preventing the e-liquid in the e-liquid bottle and the carrier from easily leaking out. Additionally, due to atmospheric pressure, the carrier allows the e-liquid to move from the e-liquid bottle to the e-liquid chamber of the second cavity without additional power assistance (e.g., no pump is needed), reducing the manufacturing cost of the slim e-cigarette. Moreover, the heating unit is detachably connected to the second cavity, so when the heating unit is damaged, it can be easily removed by simply removing the four screws on the outer cover, making replacement and maintenance of the heating unit very convenient.

[0025] In one embodiment, the heat-conducting box includes a bottom end, the heat-conducting box further includes a recess communicating with the chamber, the conveying member includes an extension arm, the conveying member is fixed in the recess and abuts against the heater, the extension arm protrudes to the bottom end of the heat-conducting box, the conduit extends into the chamber, the extension arm is located in the e-liquid and conveys the e-liquid into the heat-conducting box and contacts the heater by the capillary action, the heater heats the e-liquid and atomizes it into smoke, the smoke enters the chamber.

[0026] The conveying component can deliver an appropriate amount of e-liquid to contact the heater and the inner surface of the heat-conducting box, so that the e-liquid delivered to the inside of the heat-conducting box can be quickly heated into smoke.

[0027] In one embodiment, the heat-conducting box further includes two fixed spaces located outside the container, the two fixed spaces being heat-exchangeably connected to the heater. When the heater is operating, the temperature of the heat-conducting box rises, and a small amount of the e-liquid delivered by capillary action is heated into smoke when it comes into contact with the inner surface of the heat-conducting box.

[0028] In one embodiment, the recess includes a plurality of spaced-apart ribs, and the conveyor further includes a contact portion connected to the extension arm. The contact portion of the conveyor is housed in the recess, and the plurality of ribs press against the contact portion to form a plurality of gaps communicating with the recess between the contact portion and the inner surface of the recess. E-liquid delivered to the contact portion by capillary action comes into contact with the inner surface of the recess and is heated into smoke. The smoke enters the recess through the gaps between the contact portion and the recess.

[0029] The present invention also provides a heating unit for a slim e-cigarette, the heating unit being installed within a carrier member included in the slim e-cigarette, the carrier member containing e-liquid, characterized in that: the heating unit includes an inner cover, a heater, and a conveying member having capillary action, the heating unit further including a heat-conducting box connecting the heater and the conveying member, the heat-conducting box including a chamber located inside and separated from the heater, the heat-conducting box being separated from the e-liquid, the conveying member including a contact portion conforming to the heater and an extension arm extending outward from the heat-conducting box and having its end immersed in the e-liquid, the conveying member transporting the e-liquid into the heat-conducting box and contacting the heater to be heated into smoke, the smoke entering the chamber, the inner cover including a conduit communicating with the chamber, the smoke in the chamber moving along the conduit and leaving the chamber.

The heat-conducting box includes a bottom end, and further includes a recessed chamber communicating with the container and two fixed spaces located outside the container. The two fixed spaces are heat-exchangeably connected with the heater. When the heater is operating, the temperature of the heat-conducting box rises. The contact portion of the conveying member is fixed in the recessed chamber. The extension arm protrudes to the bottom end of the heat-conducting box and protrudes from the bottom end of the heat-conducting box and is located in the e-liquid chamber.

[0032] The heat-conducting box of the heating unit is made of a metal material with heat storage effect, which enables the heater to maintain a sufficient operating temperature during operation, thus ensuring that the e-liquid can be heated into smoke.

[0033] In one embodiment, the conduit further includes two partitions that separate an air inlet and two exhaust ducts within the conduit. The air inlet is located between the two partitions and is separated from the two exhaust ducts. The air inlet extends into the chamber, and the two exhaust ducts are connected in communication with the chamber.

The inner surface of the recess 90 is provided with a plurality of ribs 90A protrudingly.

[0060] The heat-conducting box 83 is disposed covering the outside of the heater 92. The two fixed spaces 88 are in contact with the two straight portions of the heater 92, so that the heat generated by the heater 92 is conducted to the heat-conducting box 83, thereby heating the heat-conducting box 83 as well. The arc-shaped portion of the heater 92 is housed within the recess 90 and is separated from the inner surface of the recess 90. Please refer to [link / reference]. Figure 9 As shown, the chamber 86 is located inside the heater 92 and is separated from the heater 92. One end of each of the two upper wires 191 away from the control circuit unit 179 is fixed to the carrier 44 near the assembly part 62. The two ends of the heater 92 extend to the position near the assembly part 62 and are detachably electrically connected to the two wires 191.

[0061] The heating unit 82 further includes a conveying member 94 disposed between the heater 92 and the heat-conducting box 83. The conveying member 94 may be, but is not limited to, being made of a material with capillary action. The conveying member 94 is composed of two identical units 96. The conveying member 94 includes an arc-shaped contact portion 97 and two extension arms 111 extending from both ends of the contact portion 97. The contact portion 97 includes an open end 98, which is not closed.

[0062] The contact portion 97 of the conveyor 94 fits snugly over the arcuate portion of the heater 92 and is housed within the recess 90. (See also...) Figure 11 As shown, the outer surface of the contact portion 97 is compressed by each of the ribs 90A of the recess 90, thus forming a plurality of gaps 90B between the contact portion 97 and the recess 90 that communicate with the chamber 86. The two extension arms 111 protrude from the bottom end 85 of the heat-conducting box 83. That is, the contact portion 97 of the conveyor 94 is located inside the heat-conducting box 83, and the two extension arms 111 are located outside the heat-conducting box 83.

[0063] Please see Figure 3 , Figures 7-9 As shown, the heating unit 82 further includes an inner cover 115, the inner cover 115 including a conduit 116 formed approximately at the center, the conduit 116 further including two partitions 118 spaced apart from each other, forming an air intake duct 130 between the two partitions 118, the two partitions 118 further separating two exhaust ducts 132, the two exhaust ducts 132 being spaced apart from the air intake duct 130 and located on both sides of the air intake duct 130, substantially, the length of the air intake duct 130 extending from the lower surface of the inner cover 115 is much greater than the length of the two exhaust ducts 132 extending from the lower surface of the inner cover 115.

[0064] Please see Figures 6-10As shown, the inner cover 115 is combined with the heater 92 and covers the chamber 86 of the heat-conducting box 83. The heating unit 82 and the inner cover 115 are housed together within the second cavity 52 of the support member 44. Essentially, the inner cover 115 is housed within the mounting space 60. A sealing element 131 is provided on the stepped surface formed between the inner cover 115, the mounting space 60, and the e-liquid chamber 58. The outer periphery of the inner cover 115 tightly abuts against the sealing element 131, thereby sealing the e-liquid chamber 58. The heating unit 82 is suspended within the e-liquid chamber 58 by the inner cover 115, and the two extension arms 111 of the conveyor 94 are located within the e-liquid chamber 58.

[0065] The two partitions 118 of the conduit 116 extend into the chamber 86 of the heat-conducting box 83 and are separated from the open end 98 of the conveyor 94. In other words, the air intake duct 130 extends into the chamber 86 and communicates with the chamber 86. It can be understood that in this state, the chamber 86 forms a roughly U-shaped space. Furthermore, the chamber 86 is located between the two fixed spaces 88, the recess 90, and the air intake duct 130. It can be understood that because the two exhaust ducts 132 communicate with the chamber 86, and the air intake duct 130 also communicates with the chamber 86, the two exhaust ducts 132 are indirectly connected to the air intake duct 130 through the chamber 86.

[0066] The smoke-generating device 42 further includes an outer cover 117 that is combined with the carrier 44. The outer cover 117 includes a sleeve portion 119, which includes a first channel 119A located in the center and two second channels 119B located on both sides of the first channel 119A.

[0067] The outer cover 117 is combined with the upper end 54 of the second cavity 52 and closes the installation space 60. The sleeve part 119 is sleeved in communication with the conduit 116. The first channel 119A is combined in communication with the air intake 130 of the conduit 116. The two second channels 119B are combined in communication with the two exhaust channels 132.

[0068] In the embodiment shown in the accompanying drawings of the present invention, the inner cover 115 is pressed against the outer cover 117 in the direction toward the e-liquid chamber 58, such that the outer cover 117 tightly abuts against the sealing member 131 and the heat-conducting box 83.

[0069] The smoke-generating device 42 includes a fan 78, which includes an air outlet 80. The fan 78 is fixed on the assembly part 62 of the second cavity 52 and is located outside the installation space 60 and the e-liquid chamber 58.

[0070] The thin e-cigarette 10 further includes a mouthpiece mechanism 133 disposed between the smoke outlet 26 and the support member 44 and an e-liquid bottle 171, wherein the e-liquid bottle 171 contains liquid e-liquid 175 that can be heated to form smoke 177. The e-liquid bottle 171 includes a neck 172 with external threads on its outer surface. The end face of the neck 172 is sealed with a sealing film 173, and the e-liquid 175 inside the e-liquid bottle 171 will not leak out before the sealing film 173 is broken.

[0071] Please see Figure 1 , Figure 2 , Figure 10 As shown, the mouthpiece mechanism 133 includes a first part 135 and a second part 137 joined together, the first part 135 covering the second part 137. The mouthpiece mechanism 133 further includes a first end 139, a second end 151, and a third end 153 protruding from the second part 137, the second end 151 being located between the first end 139 and the third end 153. The mouthpiece mechanism 133 further includes a first air duct 155 extending inward from the end face of the first end 139. The mouthpiece mechanism 133 further includes... Two flues 158 extending inward from the second end 151 and a generally L-shaped second air duct 156, the second air duct 156 being spaced apart between the two flues 158 and communicating with the first air duct 155, the two flues 158 being spaced apart from the first air duct 155, the mouthpiece mechanism 133 further including a third air duct 157 extending from the third end 153 toward the first air duct 155 and spaced apart from the second air duct 156, the third air duct 157 communicating with the first air duct 155, the two flues 158 communicating with the third air duct 157.

[0072] The second end 151 of the mouthpiece mechanism 133 is connected to the sleeve portion 119 of the outer cover 117 in a communicative manner. Thus, the two flues 158 are connected to the two second channels 119B, the second air duct 156 is connected to the first channel 119A, the third end 153 is aligned with and adjacent to the smoke outlet 26, and the first end 139 is connected to the air outlet 80 of the fan 78.

[0073] Please see Figure 7 , Figure 9As shown, the air outlet 80, the first air duct 155, the second air duct 156, the first channel 119A, the air inlet 130, and the chamber 86 are interconnected. Please refer to [link / reference]. Figures 8-10 As shown, the first air duct 155 is separated from the two flues 158 and is connected to the third air duct 157. In addition, the two flues 158, the third air duct 157, the two exhaust ducts 132 and the chamber 86 are interconnected.

[0074] Please see Figures 6-7 As shown, when installing the e-liquid bottle 171, the flip cap 38 is opened to expose the replacement space 23 and the connecting ring 66. The neck 172 of the e-liquid bottle 171 is then inserted into the connecting ring 66 and rotated. Guided by the internal thread 68, the e-liquid bottle 171 moves along the height direction towards the chamber 50, causing the spike 70 to pierce the sealing film 173 and the e-liquid bottle 171 to be sealed and screwed into the connecting ring 66. Due to atmospheric pressure, the e-liquid 175 in the e-liquid bottle 171 flows into the chamber 50 and the e-liquid chamber 58 through the openings 72. In addition, the viewing windows 32 of the two side walls 30 provide the function of visually viewing the remaining capacity of the e-liquid bottle 171.

[0075] It is worth mentioning that the connecting ring 66 can be, but is not limited to, made of a heat-resistant material with low thermal conductivity (such as silicone). Therefore, when the heating unit 82 is operating, the neck 172 of the e-liquid bottle 171 will not be heated and softened due to its connection with the connecting ring 66. The separator 159 also separates the heating unit 82 from the e-liquid bottle 171, so that the body of the e-liquid bottle 171 will not be heated and softened or damaged.

[0076] Please see Figures 6-7 As shown, the liquid level of the e-liquid 175 flowing into the e-liquid chamber 58 is approximately flush with the uppermost end of the connecting pipe 64. In other words, the liquid level of the e-liquid 175 in the e-liquid chamber 58 is between the bottom end 85 of the heat-conducting box 83 and the lower end 56 of the carrier 44 in the height direction and is separated from the bottom end 85, so that the heat-conducting box 83 does not directly contact the e-liquid 175.

[0077] Furthermore, since the inner cover 115, in conjunction with the sealing element 131, separates the installation space 60 and the e-liquid chamber 58, and the heat-conducting box 83 separates the container 86 from the e-liquid chamber 58, the e-liquid 175 located in the e-liquid chamber 58 will not leak out. The e-liquid bottle 171, in conjunction with the connecting ring 66, also ensures that the e-liquid 175 located in the chamber 50 will not leak out. Moreover, when the chamber 50 is filled with the e-liquid 175, the float 74 moves to approximately abut against the connecting ring 66 due to buoyancy, thus moving the magnet 76 away from the sensor 77. The control circuit unit 179 then determines that the slim e-cigarette 10 has sufficient e-liquid 175.

[0078] The e-liquid 175 located in the e-liquid chamber 58 is separated from the heat-conducting box 83 and cannot directly contact the heater 92. However, the two extension arms 111 of the conveyor 94 with capillary action are located in the e-liquid chamber 58 and their ends are immersed in the e-liquid 175. Therefore, the conveyor 94 conveys an appropriate amount of e-liquid 175 to the contact portion 97 through capillary action, so that an appropriate amount of e-liquid 175 directly contacts the heater 92 and the inner surface of the recess 90.

[0079] Assuming the vaporizer 10 is operating, the temperature of the heater 92 rises and the fan 78 operates, and the heat-conducting box 83 is also heated by the heater 92. After the e-liquid 175 (a small amount or appropriate quantity) supplied to the contact portion 97 comes into contact with the heater 92 and the inner surface of the recess 90, the e-liquid 175 is heated to a state of vaporization into smoke 177. (See [link to previous section]). Figures 7-9 As shown, the smoke 177 enters the chamber 86 through the gap 90B and each of the open ends 98.

[0080] Please see Figures 7-10 As shown, a portion of the airflow generated by the operation of the fan 78 enters the chamber 86 from the outlet 80 through the first air duct 155, the second air duct 156, the first channel 119A, and the air inlet duct 130. This causes the smoke 177 in the chamber 86 to be squeezed towards the two exhaust ducts 132. Thus, the smoke 177 in the chamber 86 sequentially enters the third air duct 157 through the two exhaust ducts 132, the two second channels 119B, and the two smoke ducts 158. The other portion of the airflow generated by the fan 78 is sequentially blown from the first air duct 155 and the third air duct 157 towards the outside of the smoke outlet 26, causing the smoke 177 to be ejected from the smoke outlet 26.

[0081] It is worth mentioning that when the thin smoke machine 10 is operating, since part of the airflow generated by the fan 78 enters the air intake duct 130, it is understood that the pressure in the air intake duct 130 will increase, so that the smoke 177 in the chamber 86 cannot enter the air intake duct 130 from the end of the air intake duct 130 located in the chamber 86, ensuring that the smoke 177 can only flow from the two exhaust ducts 132 to the third air duct 157 of the mouthpiece mechanism 133.

[0082] Assuming the e-liquid 175 in the e-liquid bottle 171 is exhausted and new e-liquid needs to be added, the cap 38 is opened to expose the replacement space 23 and the originally installed e-liquid bottle 171. The e-liquid bottle 171 is then rotated in the opposite direction to separate it from the connecting ring 66. In this way, another new e-liquid bottle 171 can be quickly connected to the connecting ring 66, allowing new e-liquid 175 to be injected into the carrier 44.

[0083] Assuming that the e-liquid 175 in the e-liquid bottle 171 and the carrier 44 is completely consumed, the magnet 76 of the float 74 will approach the sensor 77, so that the control circuit unit 179 can detect that the e-liquid 175 has been exhausted, and then the control circuit unit 179 can stop the heater 92 from continuing to heat, so that the heater 92 will not be damaged due to dry burning.

[0084] The technical features and operation of the present invention have been described in detail, and it should be understood from this that the technical features of the present invention include at least the following advantages. For example, the heat-conducting box 83 of the heating unit 82 is made of a metal material with heat storage effect, so that the heater 82 can maintain a sufficient operating temperature when it is operating, thereby ensuring that the e-liquid can be heated into smoke. In addition, the chamber 86 of the heat-conducting box 83 provides a temporary space for the smoke 177, and the smoke 177 in the chamber 86 can move to the mouthpiece mechanism 133 and be ejected along the guide of the mouthpiece mechanism 133.

[0085] Due to atmospheric pressure, the carrier 44 allows the e-liquid 175 to move from the e-liquid bottle 171 to the e-liquid chamber 58 of the second cavity 52 without additional power assistance (e.g., no pump is needed), thus reducing the manufacturing cost of the thin e-cigarette 10.

[0086] The e-liquid bottle 171 is designed to be disposable, and with the connecting ring 66, the e-liquid bottle 171 can be replaced quickly and without leakage, making the slim e-cigarette 10 very convenient.

[0087] The inner cover 115 separates the e-liquid chamber 58, which stores the e-liquid 175, from the mounting space 60, making it difficult for the e-liquid 175 in the e-liquid chamber 58 to leak out. Furthermore, the connecting ring 66 engages with the e-liquid bottle 171 in a screw-on seal, thus preventing leakage of the e-liquid 175 from both the e-liquid bottle 171 and the carrier 44.

[0088] The conveyor 94 can deliver an appropriate amount of e-liquid to contact the heater 92 and the inner surface of the heat-conducting box 83, so that the e-liquid delivered to the inside of the heat-conducting box can be quickly heated into smoke.

[0089] The design of the mouthpiece mechanism 133 divides the airflow generated by the fan 78 into two non-interfering parts, so that a single fan 78 can smoothly drive the smoke 177 out of the smoke outlet 26.

[0090] The design of the mouthpiece mechanism 133, which works in conjunction with the air intake 130 and the two exhaust ducts 132 separated by the conduit 116, ensures that the airflow generated by the fan 78 and the smoke 177 generated by the heating unit 82 are free from turbulence, and further allows the smoke 177 to be smoothly ejected from the smoke outlet 26.

[0091] Furthermore, the heating unit 82 is detachably connected to the second cavity 52, so when the heating unit 82 is damaged, it is only necessary to simply remove the four screws of the outer cover 117 (e.g., Figure 1 , Figure 3 As shown in the figure, the entire heating unit 82 can be easily removed, making the replacement and maintenance of the heating unit 82 quite convenient.

[0092] The basic teachings of the invention have been described, and many extensions and variations will be readily apparent to those skilled in the art. For example, the smoke-generating device 42 may not include the outer cover 117, in which case the mouthpiece mechanism 133 is allowed to be directly fitted onto the conduit 116, so that the smoke 177 can still be ejected from the smoke outlet 26 and the e-liquid 175 in the e-liquid chamber 58 will not leak out.

[0093] Since the embodiments disclosed in this specification can be implemented in other specific forms without departing from the spirit or general characteristics of the invention, and some of these specific forms have been pointed out, the embodiments disclosed in this specification should be regarded as illustrative rather than limiting.
