[0002] This application claims priority to Chinese patent application number 2019218803898, filed on November 4, 2019, entitled “Heating without combustion equipment and acid reduction device thereof”, the entire text of which is hereby incorporated by reference. Technical Field

[0003] The invention relates to the technical field of cigarette substitutes, in particular to a heat-not-burn device and an acid reduction device thereof. Background Art

[0004] As we all know, the smoke produced when cigarettes burn will produce a large amount of harmful substances such as tar and CO. Long-term inhalation of these harmful substances will cause great harm to the human body. In order to overcome the harm to the human body caused by harmful substances produced during smoking, low-temperature heating without burning equipment has been developed. By using low-temperature heating without burning equipment to bake tobacco products (such as cigarettes), the harm of harmful substances to the human body can be reduced as much as possible, while at the same time a certain amount of smoke can be produced to meet the smoking needs of smokers.

[0005] The low-temperature heating without burning devices currently available on the market only have basic functions and are still imperfect. The taste of the smoke is poor during the inhalation process and is generally felt to be sour. This is because when using low-temperature heating without burning devices, the smoke generated contains more acidic components and is acidic overall. In addition, because the generated smoke is in a relatively closed environment, the smoke will condense as the temperature decreases during the flow of the internal airway, and the nicotine in the smoke will also cause a certain hydrolysis reaction to produce nicotine acid, which will eventually enter the user's mouth through the suction port of the device and make the user feel the sour taste of the smoke.

[0038] like Figure 1 As shown, a heat-not-burn device 10 provided by one embodiment of the present invention includes a device body 100 and an acid reduction device 200. The device body 100 is a modular whole, which can heat tobacco products to generate smoke. The device body 100 has an air outlet 100a, and the smoke generated by the device body 100 is discharged through the air outlet of the air outlet 100a. The acid reduction device 200 is arranged at the air outlet 100a of the device body 100 to reduce the acidic substances in the smoke transmitted to the smoker, thereby improving the taste of the smoke of the heat-not-burn device 10.

[0039] like Figure 2 and Figure 3As shown, in some embodiments, the acid reduction device 200 includes a device body 210, and the device body 210 has an airway for smoke to pass through. In some embodiments, the material of the device body 210 is a weakly basic anion exchange resin. The weakly basic anion exchange resin includes a weakly basic group, which can dissociate into OH in water. － (hydroxyl ion) and is weakly alkaline. In some embodiments, the weakly alkaline group of the weakly alkaline anion exchange resin is a primary amine group (also called a primary amine group) -NH2, a secondary amine group (a secondary amine group) -NHR or a tertiary amine group (a tertiary amine group) -NR2, wherein R represents a non-H (hydrogen group). In some embodiments, the weakly alkaline anion exchange resin is a porous weakly alkaline anion exchange resin with a polystyrene skeleton and a product number of Lijiang Brand D301 produced by Lijiang Biotechnology Co., Ltd., and contains a -N(CH3)2 weakly alkaline group.

[0040] In some embodiments, the acid reduction device 200 further includes a packaging shell 220, the device body 210 is disposed in the packaging shell 220, and the packaging shell 220 has two openings for smoke to enter and exit the packaging shell 220. At this time, the acid reduction device 200 can be plugged with the gas outlet 100a of the device body 100 by interference or circumferential sealing. When the acid reduction device 200 is plugged with the gas outlet 100a of the device body 100 by interference, the acid reduction device 200 can be plugged into the gas outlet 100a of the device body 100, or the gas outlet 100a of the device body 100 can be plugged into the packaging shell 220 of the acid reduction device 200. When the acid reduction device 200 is plugged into the gas outlet 100a of the device body 100, the acid reduction device 200 can be completely accommodated in the gas outlet 100a, or the packaging shell 220 of the acid reduction device 200 can be partially accommodated in the gas outlet 100a. In some other embodiments, the packaging shell 220 may be omitted, and the device body 210 may be directly disposed in the air outlet end 100 a of the device body 100 .

[0041] In some embodiments, the device body 210 includes a plurality of weakly basic anion exchange resin particles disposed in a packaging shell 220, and the plurality of weakly basic anion exchange resin particles are stacked to form the device body 210 having an airway. In some embodiments, when the weakly basic anion exchange resin particles are porous particles, the holes of the particles also constitute the airway of the device body 210. In some other embodiments, the device body 210 may not be formed by stacking granular alkaline anion exchange resins, and the device body 210 may directly be a block structure such as a porous block, a cylindrical block, etc.

[0042] like Figure 3 and Figure 4As shown, in some embodiments, the device body 100 includes a first end 102 and a second end 104, and a smoke channel 106 for exhausting smoke, and the smoke channel 106 includes a first air outlet 1062 located at the first end 102, wherein the first end 102 is the air outlet end 100a of the device body 100.

[0043] In some embodiments, the device body 100 further includes a heating chamber 110 , which can heat tobacco products (usually containing shredded tobacco in traditional cigarettes) in the heating chamber 110 to generate smoke. The end of the smoke channel 106 away from the first air outlet 1062 is connected to the heating chamber 110 .

[0044] In some embodiments, the first end 102 is further provided with an insertion port 108 for inserting tobacco products, and the insertion port 108 is connected to an end of the heating chamber 110 away from the smoke channel 106, that is, both ends of the heating chamber 110 are respectively connected to the insertion port 108 and the smoke channel 106. The insertion port 108 and the first air outlet 1062 are both located at the first end 102, so that the heating chamber 110 and the smoke channel 106 can be connected at the second end 104, and the smoke in the heating chamber 110 can flow from the second end 104 to the first end 102 through the smoke channel 106, and then flow out through the first air outlet 1062. In this way, the smoke channel 106 can cool the smoke generated by the heating chamber 110 (for the device body 100, in order to allow substances such as nicotine in the tobacco products to evaporate better, the temperature of the heating chamber 110 needs to be set at a higher range, for example, above 100°C. Therefore, the temperature of the smoke generated by heating the tobacco products in the heating chamber 110 is relatively high, and the smoke is directly transmitted to the smoker, which can easily burn the smoker).

[0045] In some embodiments, an inner heat insulating sleeve 112 and an outer heat insulating sleeve 114 are disposed outside the heating chamber 110, and the heating chamber 110, the inner heat insulating sleeve 112 and the outer heat insulating sleeve 114 are sequentially connected. The inner heat insulating sleeve 112 and the outer heat insulating sleeve 114 can effectively prevent the heat in the heating chamber 110 from being dissipated.

[0046] like Figure 3-Figure 5 As shown, in some embodiments, the device body 100 further includes a filter 120, which is located at the second end 104 and connects the heating chamber 110 and the smoke channel 106. The filter 120 can purify the smoke, purify some organic pollutants, dust, water vapor (part of the water vapor will condense at the filter 120 to form condensed water), etc. in the smoke, thereby improving the quality of the smoke. In addition, the filter 120 can also cool the smoke, thereby reducing the temperature of the smoke. In some embodiments, the filter 120 is filled with at least one of materials such as activated carbon and porous ceramics.

[0047] In some embodiments, the device body 100 further includes a housing 130, which includes an inner housing 132 and an outer housing 134, that is, the housing 130 is a double-layer housing structure, which can achieve better heat insulation effect and prevent the housing 130 from being overheated due to the operation of the heating chamber 110. In some embodiments, the inner housing 132 and the outer housing 134 are made of different materials, and the heat conduction effect of the inner housing 132 is worse than that of the outer housing 134. In this way, better heat insulation can be achieved.

[0048] In some embodiments, the inner shell 132 is provided with a notch 1322, the notch 1322 is located at the second end 104, the filter 120 is detachably connected to the notch 1322, and fills the notch 1322. The outer shell 134 includes a first outer shell portion 1342 and a second outer shell portion 1344, the first outer shell portion 1342 is closer to the first end 102 than the second outer shell portion 1344, the second outer shell portion 1344 is detachably connected to the inner shell 132, and can be docked with the first outer shell portion 1342 to form the outer shell 134. In this way, the filter 120 can be accommodated in the outer shell 134, so that the integrity of the heating without burning device 10 is better. Moreover, the second outer shell portion 1344 is detachably connected to the inner shell 132, and the filter 120 is detachably connected to the notch 1322, which is very convenient for replacing the filter 120. In some embodiments, the filter 120 is connected to the notch 1322 by a card block and a card slot, and the second outer shell portion 1344 is also connected to the inner shell 132 by a card block and a card slot.

[0049] In some embodiments, the device body 100 further includes a battery 140, and the battery 140, the smoke channel 106, and the heating chamber 110 are arranged in sequence along a first direction along the device body 100, and the first direction is perpendicular to the direction from the first end 102 to the second end 104. In this way, it is easy to control the height of the device body 100, and it can be avoided that the high temperature of the heating chamber 110 has an adverse effect on the battery 140.

[0050] In some embodiments, the device body 100 further includes a main control board 150, a key switch 160, and a charging interface 170. The main control board 150 is located on a side of the battery 140 away from the smoke passage 106, and is electrically connected to the battery 140. The key switch 160 is convexly disposed on the housing 130, and is electrically connected to the main control board 150. The charging interface 170 is exposed from the second end 104, and is electrically connected to the main control board 150.

[0051] In some embodiments, the device body 100 further includes a cover 180 , which is openable and closable and is disposed on the first end 102 to open or close the insertion port 108 and the first air outlet 1062 .

[0052] In some embodiments, the acid reduction device 200 includes a device body 210 and a mouthpiece structure 220, and the device body 210 is disposed in the mouthpiece structure 220. The mouthpiece structure 220 is disposed on the cover 180, and the mouthpiece structure 220 is connected to the smoke channel 106 through the first air outlet 1062, and the end of the mouthpiece structure 220 located outside the cover 180 is the mouthpiece of the heat-not-burn device 10. In some other embodiments, when the sealing requirements for the heat-not-burn device 10 are not high, the cover 180 can be omitted. In this case, part of the mouthpiece structure 220 can be inserted into the first air outlet 1062, and the packaging shell located outside is the mouthpiece of the heat-not-burn device 10.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the acid reduction device 200 further includes a dehydration structure 230 connected to the mouthpiece structure 220, a second air outlet 222 is provided at one end of the mouthpiece structure 220 away from the dehydration structure 230, and a second air inlet 232 is provided at one end of the dehydration structure 230 away from the mouthpiece structure 220. The acid reduction device 200 is connected to the first air outlet 1062 via the second air inlet 232. The dehydration structure 230 can remove at least part of the water vapor in the smoke, thereby reducing the probability of the hydrolysis reaction, and can also reduce the moisture of the smoke transmitted to the smoker, making the smoke taste richer.

[0054] In some embodiments, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the cover 180 is used to cover the end surface of the device body 100 and is provided with a receiving cavity 180a, and the cover 180 is provided with a clearance hole 180b connected to the receiving cavity 180a. The water removal structure 230 is accommodated in the receiving cavity 180a, and the mouthpiece structure 220 is penetrated on the clearance hole 180b. In some embodiments, the acid reduction device 200 is detachably connected to the cover 180. Since the cover 180 is openable and closable and is provided on the first end 102, it is very convenient to replace the acid reduction device 200 on the end surface of the device body 100 covered by the cover 180.

[0055] When the cover 180 is in the closed state, the cover 180 covers the first air outlet 1062 and the insertion port 108, and the second air inlet 232 is connected to the first air outlet 1062 and is circumferentially sealed. During inhalation, smoke generated by the device body 100 enters the dehydration structure 230, and after being dehydrated by the dehydration structure 230, flows out through the second air outlet 222. When the cover 180 is in the open state, the acid reduction device 200 and the cover 180 can be disassembled.

[0056] In the above-mentioned heating without burning device 10, the acid reduction device 200 can be replaced by opening and closing the cover 180, and the convenience of replacing the acid reduction device 200 is good. Moreover, when the cover 180 is in the covered state, the cover 180 covers the first air outlet 1062 and the insertion port 108, and the second air inlet 232 is connected to the first air outlet 1062, and the circumferential sealing is achieved, which has good air tightness.

[0057] like Figure 4 and Figure 5 As shown, in some embodiments, one side edge of the cover 180 is hinged to the device body 100 via a hinge 300. Thus, when the cover 180 is in an open state, the cover 180 is still connected to the device body 100, which is more convenient to replace the acid reduction device 200 than when the cover 180 is separated from the device body 100.

[0058] like Figure 8 and Fig. 9 As shown, in some embodiments, the device body 100 is provided with a first magnetic member 190, and the cover 180 is provided with a second magnetic member 182, and the cover 180 and the device body 100 are magnetically matched through the second magnetic member 182 and the first magnetic member 190. At this time, when the cover 180 and the device body 100 are magnetically matched, the cover 180 is in a covered state, and when the cover 180 is separated from the device body 100, the cover 180 is in an open state. The magnetic matching of the cover 180 and the device body 100 is very convenient for the cover 180 and the device body 100 to be openably connected. In some other embodiments, the cover 180 and the device body 100 can also be connected by interference fit, or by the card block and the card slot. The card can be connected.

[0059] In some embodiments, the device body 100 further includes a packaging plate 192, which is located at the first end 102 and connected to the housing 130. The first air outlet 1062 and the insertion port 108 are both located on the packaging plate 192. The first magnetic member 190 is located in the housing 130 and is located on a side of the packaging plate 192 away from the cover 180. In other embodiments, when the packaging plate 192 is a magnetic plate, the first magnetic member 190 can be omitted.

[0060] In some embodiments, the second magnetic member 182 includes a plurality of second magnetic blocks 1822, which are arranged at intervals and located at a side edge of the cover 180 away from the hinge 300. The first magnetic member 190 includes a plurality of first magnetic blocks 190a, which are arranged one-to-one with the plurality of second magnetic blocks 1822. In this way, better airtightness can be achieved and the cover 180 can be easily opened and closed.

[0061] like Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the cover 180 includes an outer cover 184 and an inner cover 186 connected to each other. In some embodiments, the outer cover 184 and the inner cover 186 are fixedly connected by screws 188. The accommodating chamber 180a is located on the inner cover 186, and the clearance hole 180b runs through the inner cover 186 and the outer cover 184. The inner cover 186 also includes a clearance groove 180c, which is directly connected to the insertion port 108 to accommodate part of the tobacco products. Among them, at least part of the inner cover 186 is spaced from the outer cover 184 and forms an air intake channel 180d. The outer cover 184 is provided with an air intake hole 1842 connecting the outside air and the air intake channel 180d, and the side of the clearance groove 180c away from the device body 100 (the bottom of the clearance groove 180c) is provided with a vent 1862 connecting the air intake channel 180d and the clearance groove 180c. In this way, when the tobacco product is an ordinary cigarette, the filter tip of the cigarette can be placed in the yield groove 180c to avoid being heated by the heating chamber 110, and the outside air can enter the cigarette from the top of the cigarette (filter tip) through the air inlet hole 1842, the air inlet channel 180d and the vent hole 1862 in sequence, and then pass through the cigarette, so as to better remove the smoke from the cigarette.

[0062] In some embodiments, the second magnetic member 182 is disposed on a side of the inner cover 186 away from the device body 100. In other embodiments, when the inner cover 186 is a magnetic cover, the second magnetic member 182 can be omitted.

[0063] In some embodiments, the water removal structure 230 includes a water absorbent, a main body 234 for accommodating the water absorbent, and a rubber connector 236 that is inserted into the main body 234. In some embodiments, the water absorbent is cotton. The rubber connector 236 is a hollow structure with two ends open, and the second air inlet 232 is located on the rubber connector 236. When the cover 180 is in a covered state, the rubber connector 236 contacts the end face of the first end 102, so that the second air inlet 232 is connected to the first air outlet 1062 and is circumferentially sealed. When the cover 180 and the device body 100 are magnetically matched, the rubber connector 236 is set, which can have very good sealing. It can be understood that in some other embodiments, the rubber connector 236 can also be omitted. At this time, the end face of the cover 180 and the end face of the device body 100 are magnetically contacted, and better sealing can also be achieved.

[0064] In some embodiments, the mouthpiece structure 220 includes a tubular body 224 and a cover 226 sleeved on the tubular body 224. The side of the main body 234 away from the device body 100 is an open side, and the cover 226 is connected to the open side and closes the open side. In this way, it is very convenient to encapsulate cotton in the main body 234. In some embodiments, the cover 226 is ultrasonically fused with the open side, so that the cover 226 is fixedly connected to the open side. In some embodiments, the cover 226 is detachably connected to the open side, so that the cover 226 can be opened. After the cotton is replaced in the main body 234, the cover 226 closes the open side again, thereby making the mouthpiece structure 220, the main body 234 and the rubber connector 236 reusable and more environmentally friendly.

[0065] In some embodiments, the mouthpiece structure 220 further includes a cap 228, which is located outside the cover 180 and is detachably connected to the tubular body 224. The cap 228 includes a first portion 2282 and a second portion 2282 connected to each other, the first portion 2282 being sleeved on the tubular body 224, and the second portion 2282 being covered on an end of the tubular body 224 away from the cover 226 to block the second air outlet 222. In this way, when the heat-not-burn device 10 is not in use, the outside air can be effectively prevented from affecting the performance of the dewatering structure 230, thereby extending the service life of the dewatering structure 230. In some embodiments, the first portion 2282 and the second portion 2282 are both interference fit with the tubular body 224. In some other embodiments, the first portion 2282 can be omitted.

[0066] In some embodiments, the mouthpiece structure 220 further includes a stopper 229, which is disposed in the tubular body 224 and is closer to the second air outlet 222 than the device body 210. The stopper 229 is spaced a certain distance from the device body 210 and forms a gap, so that when the device body 210 is formed by granular weakly basic anion exchange resin, during suction, the airflow will drive the granular weakly basic anion exchange resin to move in the gap, thereby reducing suction resistance. In some embodiments, the stopper 229 is cotton. In some other embodiments, the stopper 229 may also be a porous air-permeable plate.

[0067] In some embodiments, the cover 180 is provided with a third magnetic member 189, and the acid reduction device 200 is provided with a fourth magnetic member 240, and the acid reduction device 200 and the cover 180 are magnetically matched through the fourth magnetic member 240 and the third magnetic member 189.
