Description

Technical Field

[0001] The present invention relates to the field of atomization devices, and more particularly to an electronic atomization device and a smoking assembly. Background Art

[0002] Traditional smoking is done by lighting tobacco with an open flame, which produces smoke for smokers to inhale. The smoke produced by burning tobacco usually contains thousands of harmful substances. Therefore, traditional tobacco not only causes serious respiratory diseases to smokers, but also easily causes the harm of secondhand smoke.

[0003] In order to solve the technical problem that more harmful substances are produced by burning traditional tobacco, technicians have developed atomized electronic cigarettes and electronic flue-cured cigarettes. However, the atomized electronic cigarette forms smoke by atomizing the smoke liquid for smokers to inhale. Although the atomized electronic cigarette overcomes the above shortcomings of traditional cigarettes and can satisfy consumers' dependence on tobacco to a certain extent, the smoke liquid of the electronic cigarette is prepared by flavors and spices, and is not a real cigarette product. Its smoke taste is light and lacks the aroma of tobacco, and it cannot be widely accepted by consumers. The existing low-temperature electronic flue-cured cigarette uses a low-temperature (below 360 degrees Celsius) non-combustion method to heat the tobacco. Due to its low heating temperature, the harmful substances produced by heating are few, but the amount of smoke is obviously insufficient. If the tobacco is heated at a high temperature, it is easy to blacken the tobacco and carbonize it, and the heat distribution is uneven, which is easy to produce the problem that some tobacco has been carbonized while the temperature of another part is not enough, and thus more harmful substances are also produced. How to be able to suck out the aroma of tobacco and reduce harmful substances to a large extent has become a problem that the tobacco industry needs to solve urgently.

[0004] In the related art, in addition to using an atomizing component to atomize the liquid medium, a baking unit is also used to bake the solid smoke medium to solve the above problems.

The atomization unit 20 is used to atomize liquid media such as smoke liquid. It can be understood that in some other embodiments, the atomization unit 20 can be omitted, and the baking unit can bake the smoke assembly 40 to generate smoke for the user to inhale. The baking unit 80 is used to heat solid smoke media such as the smoke assembly 40 (flavor bomb) to form smoke. The atomization unit 20 and the baking unit 80 are installed side by side on the upper part of the housing 10, that is, installed in the horizontal direction of the upper part of the housing 10. The smoke assembly 40 can be placed in the baking unit 80, and it can generate smoke for the user to inhale under the baking of the baking unit 80. The power supply unit 50 is used to supply power to the atomization unit 20 and the baking unit 80, and is installed at the lower part of the shell 10, that is, the power supply unit 50, the atomization unit 20 and the baking unit 80 are distributed in the longitudinal direction of the shell 10. The air switch unit 60 is installed between the baking unit 80 and the power supply unit 50, and is used to control the connection and disconnection between the power supply unit 50 and the atomization unit 20 and the baking unit 80 through the driving of the airflow. The main control unit 70 is installed on the side of the shell 10, and is used to realize the unlocking, data input, control and other functions of the electronic atomization device 1. The connecting unit 30 is arranged at the lower part of the baking unit 80, and is used to connect the baking unit 80 and the atomization unit 20, so that the smoke and mist can be mixed and then discharged, thereby meeting the user's requirements. See also Figure 3 and Figure 4 In some embodiments, the atomizing unit 20 is detachably mounted in the housing 10 so that the atomizing unit 20 can be replaced. The power supply unit 50 includes a battery.

[0053] Read also Figure 5 and Figure 6 In some embodiments, the housing 10 may be in a longitudinally long and flat shape, and may include a sleeve 11, a bracket 13 disposed in the sleeve 11, and a nozzle 15 installed at the top of the bracket 13. In some embodiments, the sleeve 11 may be in a longitudinally long and flat shape, and may be sleeved on the periphery of the bracket 13. The bracket 13 may be used for installing the atomization unit 20, the power supply unit 60, the main control unit 70, and the communication unit 30. In some embodiments, the nozzle 15 may be cylindrical, and may be used by the user to inhale tobacco.

[0054] In some embodiments, the bracket 13 may be integrally formed with the sleeve 11 and the nozzle 15, and may include a first receiving space 131 for receiving the atomization unit 20, a second receiving space 132 for receiving the baking unit 80, a third receiving space 133 for receiving the power supply unit 50, a fourth receiving space 134 for receiving the air switch unit 60, a fifth receiving space 135 for receiving the main control unit 60, and a sixth receiving space 136 for receiving the connection unit 30. A partition wall 137 is provided between the first receiving space 131 and the third receiving space 133, which can be used to separate the first receiving space 131 from the third receiving space 133.

[0055] In some embodiments, a pair of electrode holes 1371, a pair of magnetic element receiving holes 1372, and an arc-shaped first air guide groove 1373 are provided on the top surface of the partition wall 137. The pair of electrode holes 1370 are spaced apart and distributed in the length direction of the partition wall 137, and the first air guide groove 1373 extends from the first end away from the third receiving space 134 to the second end close to the third receiving space 134. The third receiving space 133 is located at the far end away from the suction nozzle 15, and the first receiving space 131 and the second receiving space 132 are located at the near end close to the suction nozzle 15. Accordingly, the power supply unit 50 is located at the far end away from the suction nozzle 15, and the atomization unit 20 and the baking unit 80 are located at the near end close to the suction nozzle 15. Such a layout makes the structure of the entire electronic atomization device 1 more compact. The partition wall 137 also includes a second air guide groove 1374 that is connected to the second end of the first air guide groove 1373 and sinks longitudinally downward, and a third air guide groove 1375 that connects the second air guide groove 1374 with the third receiving space 134, so as to form a first air flow channel connected to the air switch unit 60. The first air guide groove 1373 is arranged in an arc shape, which can reduce the probability of liquid leakage entering the air switch unit 60 to a certain extent, so as to prevent the adverse effects of liquid leakage on the air switch unit 60. Preferably, the bottom of the second air guide groove 1374 is lower than the end of the third air guide groove 1375 connected to the second air guide groove 1374, so that even if the liquid leakage enters the first air flow channel, the lower end of the second air guide groove 1374 can also receive a part of the liquid leakage, further reducing the possibility of liquid leakage entering the air switch unit 60.

[0056] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the housing 10 further includes a pair of electrode contacts 12, a pair of magnetic bodies 14, and a cover 17; the electrode contact 12 can be inserted into the electrode hole 1370 and electrically connected to the power supply unit 50. The magnetic body 14 is embedded in the magnetic element receiving hole 1372 to adsorb the atomization unit 20. The cover 17 is sealed on the top of the partition 137 to seal the first air guide groove 1373. The cover 17 is also provided with an opening (unnumbered) for exposing the electrode contacts 12 and the magnetic body 14. The cover 17 is provided with an air vent 170 connected to the first end of the first air guide groove 1373, and the air vent 170 is used to connect the first air flow channel with the air guide hole 212 of the atomization unit 20.

[0057] For example Figures 2 to 4 As shown, in some embodiments, the atomization unit 20 may include a base 21, an atomization assembly 22 disposed on the base 21, an atomization shell 23 sleeved on the base 21, and a pair of electrodes 24 conductively connected to the atomization assembly 22. The atomization shell 23 defines a liquid storage chamber 230 for accommodating a liquid medium. The top liquid absorption surface of the atomization assembly 22 is exposed in the liquid storage chamber 230 to be connected to the liquid storage chamber 230. The atomization assembly 22 may include a porous body and a heating element disposed on the porous body, and the heating element may be conductively connected to the electrode 24 through a conductive connection portion. The base 21 includes a second air flow channel 210 disposed laterally, and the second air flow channel 210 is located below the atomization assembly 22, and the bottom atomization surface of the atomization assembly 22 is exposed in the second air flow channel 210. The atomizing shell 23 is provided with a first air inlet 231 and a first air outlet 232 on opposite sides of the outer and inner sides, respectively, and the first air inlet 231 and the first air outlet 232 are respectively connected to the second air flow channel 210, and the first air inlet 231 is located on the side of the atomizing unit 20 away from the baking unit 80, which allows the outside air to enter the second air flow channel 210 and mix with the mist generated by the atomizing assembly 22, and the first air outlet 232 is located on the side of the atomizing unit close to the baking unit 80, which allows the mixed gas to flow out of the atomizing unit 20. The outer side of the atomizing shell 23 is also provided with a plurality of protruding push portions 233, so as to facilitate pushing the atomizing unit 20 out of the housing 10. Correspondingly, the sleeve 11 of the housing 10 is provided with a notch 110 for exposing the push portion 233. In some embodiments, the base 21 may further include an air guide hole 212, one end of which is connected to one end of the second air flow channel 210 close to the first air inlet 231, and the other end of which extends downward to the bottom surface of the base 21, and is used to be connected to the first air flow channel in the bracket 13. The pair of electrodes 24 penetrates from the bottom surface of the base 21 to be conductively connected to the electrode contacts 12, and is conductively connected to the conductive connection portion of the heating element of the atomizer assembly 22.

[0058] In some embodiments, the baking unit 80 may be cylindrical and longitudinally arranged in the housing 10, with its lower end connected to the connecting unit 30 and its upper end connected to the suction nozzle 15. In some embodiments, the baking unit 80 may include a cylindrical heating element and a cylindrical heat conductor coaxially arranged inside the heating element. The inner side of the heating element forms a baking cavity, which can be used to accommodate the smoking assembly 40. The baking cavity 310 has a second air inlet at the bottom and a second air outlet at the top; the second air inlet is connected to the connecting channel 80. The cylindrical heat conductor can be placed at the second air outlet end of the baking cavity, and can be made of materials with good thermal conductivity such as copper, aluminum, stainless steel, etc. The baking unit 80 can heat solid smoking media such as tobacco in a low-temperature non-combustion manner. Since its heating temperature is low, less harmful substances are generated by heating. Preferably, the heating temperature of the baking unit 80 is to keep the internal temperature of the smoking solid smoking medium at 40 to 50 degrees. In some embodiments, the heating temperature of the baking unit 80 is between 45 degrees and 55 degrees.

[0059] like Figure 7 and Figure 8 As shown, in some embodiments, the communication unit 30 may include a front half 31 and a rear half 32 spliced ​​together, and a first arc-shaped groove 310 with a semicircular cross section is formed on the surface opposite to the front half 31 and the rear half 32. A second arc-shaped groove 320 with a semicircular cross section is formed on the surface opposite to the front half 31 of the rear half 32, and a third air outlet 322 connected to the upper end of the second arc-shaped groove 320 is also provided on the top of the rear half 32, and a third air inlet 321 connected to the lower end of the second arc-shaped groove 320 is provided on the side of the rear half 32 adjacent to the atomization unit 20. After the front half 31 and the rear half 32 are spliced, an arc-shaped communication channel 33 is formed to guide the horizontal airflow into a longitudinal airflow.

[0060] For example Figure 2 As shown, the connecting channel 33 connects the transverse second air flow channel 210 of the atomizing unit 20 with the longitudinally arranged baking chamber of the baking unit 80. One end of the connecting channel 33 is connected to the first air outlet 232, and the other end is connected to the second air inlet. A circular groove 323 is also provided on the top of the rear half 32, and the groove 323 is tightly sleeved on the bottom end of the baking unit 80, so that the connecting channel 33 is tightly connected to the baking chamber of the baking unit 8030.

[0061] like Figures 9 to 11As shown, the smoke generating assembly 40 can be accommodated in the baking chamber and can be detachably mounted with the baking chamber 310. The smoke generating assembly 40 can include a solid smoke generating medium, a spoiler 41 and a receiving device 42; the solid smoke generating medium can include tobacco particles or tobacco leaves, which can be heated by a low-temperature non-combustion method to generate smoke for users to inhale. In some embodiments, the solid smoke generating medium can be columnar, and the spoiler 41 can be embedded in the solid smoke generating medium and can be arranged along the longitudinal direction of the solid smoke generating medium, which can increase the average airflow velocity by spoiling the flow, improve the uniformity of the velocity, make the airflow have sufficient contact with the tobacco leaves, and improve the convective heat exchange and the release and transmission of nicotine.

[0062] The spoiler 41 may be spiral in some embodiments and may extend in the longitudinal direction of the solid smoke-generating medium. It may include a central column 411 and three spoilers 412 arranged at intervals. The central column 41 may be integrally formed with the spoiler 412, and in some other embodiments, it may also be omitted. The spoiler 412 may be one or more, and is not limited to three. The three spoilers 412 may be arranged at intervals along the circumferential direction on the outer peripheral wall of the central body 411, and each spoiler 412 may extend along the axial direction of the central column. The spoiler 412 may be spiral in some embodiments, and a spiral airflow channel 413 in the shape of a spiral may be defined thereon; the spiral airflow channel 413 may be arranged between two adjacent spoilers 412, and it may allow gas to pass into the solid smoke-generating medium. The spiral airflow channel 413 may extend in the longitudinal direction and communicate with the second airflow channel 210. By spirally arranging the spiral airflow channel 413, the path of the gas can be increased, thereby improving the uniformity of the speed, and the contact area between the solid smoke-generating medium and the gas can be increased, so that the airflow passing through the solid smoke-generating medium can be in more complete contact with the solid smoke-generating medium, thereby improving the release and transmission of nicotine.

[0063] Read also Fig.14a to Fig.16b In some embodiments, when there is no spoiler 41, the average flow velocity of the longitudinal section is 0.503 m / s. After adding the spoiler, the average flow velocity of the longitudinal section is 0.573 m / s, and the average velocity of the longitudinal section is increased by 13.9%; when there is no spoiler 41, the average flow velocities of the cross-sections of each section of the solid smoke medium sequentially arranged along the gas flow direction are 0.456 m / s, 0.439 m / s, and 0.395 m / s, respectively; after adding the spoiler, the average flow velocities of the cross-sections of each section of the solid smoke medium sequentially arranged along the gas flow direction are 0.539 m / s, 0.539 m / s, and 0.559 m / s, respectively, and the average velocity of the cross-section is increased by 21.5%.

[0064] like Fig.17a and Fig.17bAs shown, the spoiler 41 can very effectively increase the release of nicotine in the raw material. After adding the spoiler 41, the less the raw material, the more nicotine is released, and the more obvious the improvement effect is. Specifically, adding the spoiler 14 allows the airflow to fully contact the smoke-generating medium, thereby increasing the release of nicotine and reducing the amount of raw materials in the solid smoke-generating medium by 2 / 3, thereby greatly reducing the cost.

[0065] The receiving device 42 may be cylindrical in some embodiments, and may be used to receive the solid smoke-generating medium. It may be a metal sleeve with good thermal conductivity, and the bottom surface of the sleeve may be provided with an air inlet to communicate with the second communication channel 210 for gas to enter. It can be understood that in some embodiments, in other embodiments, it may be a wrapping paper wrapped around the solid smoke-generating medium, and it may not be limited to a sleeve.

[0066] In some embodiments, the smoke generating assembly 40 may further include a mounting sleeve 43 mounted in the receiving device 42 and located at one end near the suction nozzle 15, and a filter cotton 44 mounted in the mounting sleeve 43; it can be understood that in some embodiments, the mounting sleeve 43 may be omitted. The filter cotton 44 is received in the receiving device 42 and is located at one end of the receiving device 42 near the suction nozzle 15. In some embodiments, the filter cotton 44 may be columnar, which can be used to filter the smoke generated by the solid smoke generating medium.

[0067] like Fig.12 and Fig.13 As shown, in some embodiments, the air switch unit 60 may include a mounting base 61 and an air switch 62 mounted in the mounting base 61, and the mounting base 61 includes a receiving cavity 610 with an opening at the top. Figure 4 and Figure 5 It can be seen that the air switch 62 is mounted upside down in the top opening, and a gap is formed between the top trigger surface of the air switch 62 and the bottom of the receiving chamber 610, and the mounting seat 61 also includes a connecting pipe 612 that connects the gap to the outside. The connecting pipe 612 is used to communicate with the second air flow channel in the housing 10. In this way, the trigger surface of the air switch 62 is connected to the second air flow channel 210 of the atomizing unit 20 via the first air flow channel. When the second air flow channel 210 has air flow suction, a negative pressure will be formed in the first air flow channel, and then a negative pressure will be formed at the trigger surface of the air switch 62, so that the air switch 62 is turned on. It should be noted that since the air switch 62 is mounted upside down, a gap is formed between it and the bottom of the receiving chamber 610, so that even if the receiving chamber 610 enters the leakage, it is not easy to touch the trigger surface of the air switch 62, thereby further ensuring the normal operation of the air switch 62.

[0068] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
