Description

Technical Field

[0002] Currently in the electronic atomization industry, the smoke paste type aerosol generating device is mainly a smoke generating device suitable for solid atomization media. Compared with real cigarettes that burn tobacco, its advantage is that it uses evaporation or baking to replace the combustion process, avoiding the production of many irritating toxic and carcinogenic substances, and has a purer taste. It can be applied to various types of solid atomization media.

[0003] The common cigarette paste aerosol generating device usually includes the following components, namely, a cigarette paste box, an atomizer assembly and a battery. Among them, in the traditional structure, the atomizer assembly is arranged on the upper part of the battery, that is, between the mouthpiece and the battery, and the atomizer assembly includes an airway tube and an atomizer core, and the atomizer core is arranged in the airway tube. When in use, the battery energizes the atomizer core, so that the atomizer core generates heat to heat the cigarette paste in the cigarette paste box, and the user generates aerosol by inhalation. However, after a long period of use, a large amount of condensed substances or other impurities will remain in the airway tube. Over time, these condensed substances or impurities will cause blockage in the airway. Since the atomizer core is arranged in the airway tube, if the airway tube is to be cleaned, the airway tube must be disassembled first, and then the atomizer core must be removed from the airway tube to clean the airway tube. Since the volume of the airway tube and the atomizer core is relatively small, it is time-consuming and laborious to disassemble, which causes great inconvenience to the user. Utility Model Content

[0033] An embodiment of the present application provides an aerosol generating device, which is used to heat an atomizing medium (such as tobacco paste or tobacco liquid) inside the aerosol generating device to form an aerosol for a user to inhale.

[0034] The following is an example of an electronic atomization device for heating solid cigarette paste to generate aerosol as an aerosol generating device to illustrate the structure of the aerosol generating device in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the aerosol generating device of the present application is not limited to the above-mentioned electronic atomization device for heating solid cigarette paste, but can also be other aerosol generating devices for heating solid atomization media to generate aerosols, which is not limited here.

[0035] See Figures 1 to Figure 5 , FIG. 1 and FIG. 2 show the appearance of an aerosol generating device 10 in one embodiment of the present application, Figure 3FIG. 1 shows an explosion diagram of the aerosol generating device 10 in this embodiment. Figure 4 and Figure 5 The internal structure diagram of the aerosol generating device 10 in this embodiment is shown. The aerosol generating device 10 provided in one embodiment of the present application comprises a housing 100, an atomizing unit 200 and a power supply unit 300, wherein the housing 100 is provided with an air outlet 101 and mounting grooves 103 penetrating the housing 100 on opposite sides thereof, the mounting groove 103 is provided at one end of the housing 100 away from the air outlet 101, the groove wall of the mounting groove 103 is provided with an air hole 102 arranged at a relative interval from the air outlet 101, and the housing 100 is also provided with a main air passage 401, the air hole 102 and the air outlet 101 are connected to each other through the main air passage 401; the atomizing unit 200 and the power supply unit 300; 00 is detachably connected to the shell 100, and is provided with an air inlet 201 connected to the air outlet 101. The power supply unit 300 is arranged in the shell 100 and is electrically connected to the atomization unit 200, and is used to supply power to the atomization unit 200 so that it can generate heat energy; the atomization unit 200 is used to heat the atomization medium contained therein to generate an aerosol. When the user inhales, the airflow can enter the atomization unit 200 from the air inlet 201, and after mixing with the aerosol, it is discharged through the air hole 102, the main airway 401 and the air outlet 101 in sequence to be inhaled by the user.

[0036] Specifically, in one embodiment, Figure 3 and Figure 4 As shown, an airway tube 400 is provided in the housing 100 , and a main airway 401 runs through opposite ends of the airway tube 400 . More specifically, the top of the shell 100 is provided with a nozzle 104, and the air outlet 101 runs through the opposite ends of the nozzle 104. A first seal 500 made of silicone is provided at a position near the nozzle 104 in the accommodating chamber, and a second seal 600 made of silicone is also provided in the accommodating chamber. The first seal 500 and the second seal 600 are arranged relatively spaced apart, the nozzle 104 is inserted into one side of the first seal 500, one end of the airway tube 400 is inserted into the side of the first seal 500 facing away from the nozzle 104, and the other end of the airway tube 400 is inserted into the second seal 600. The first seal 500 is used to prevent the condensate generated by the aerosol from flowing back into the shell 100 from the nozzle 104 and causing a short circuit in the power supply unit 300, and the second seal 600 is used to prevent the condensate in the airway tube 400 from flowing back into the atomization unit 200.

[0037] In this way, by detachably inserting the atomizing unit 200 into the mounting groove 103, one end of the airway tube 400 is connected to the air outlet 101, and the other end is directly connected to the mounting groove 103 through the air hole 102, so that there are no other components in the airway tube 400. Compared with the structure in which the atomizing core 230 in the existing aerosol generating device is usually required to be arranged in the airway tube 400, this structure makes it easier for users to clean the condensed substances or other impurities remaining in the main airway 401. The user only needs to use the matching straight brush, insert it into the main airway 401 from the air outlet 101 at the suction nozzle 104, and then directly penetrate the entire main airway 401, and clean all the impurities in the airway from the air hole 102, without any residual impurities, and the cleaning effect is very good. At the same time, there is no need to disassemble individual parts for cleaning, and the cleaning operation is very convenient.

[0038] Preferably, the outer diameter of the airway tube 400 is 0.5 cm to 1 cm. Setting the diameter of the airway tube 400 to a size within the above range can be more conducive to the layout of various components in the shell 100, thereby saving space, and is also conducive to the convenient selection of suitable cleaning tools to penetrate into the main airway 401 to clean the airway tube 400.

[0039] It is worth noting that since the airway tube 400 is a standard part with a fixed length, the depth of insertion of both ends of the airway tube 400 into the first seal 500 and the second seal 600 must be limited to prevent one end of the airway tube 400 from being inserted too deeply and causing the other end to fall off from the first seal 500 or the second seal 600. Figure 4 In a preferred embodiment, a limiter 700 is further provided on the outer circumferential surface of the airway tube 400, one side of the limiter 700 abuts against the second sealing member 600, and the inner circumferential surface of the limiter 700 and the outer circumferential surface of the airway tube 400 have a step so that the limiter 700 can limit the insertion depth of the airway tube 400 into the second sealing member 600.

[0040] It is understandable that the limiting member 700 and the airway tube 400 may be integrally connected, or may be fixedly connected to the airway tube 400, which is not limited here.

[0041] In terms of the connection between the atomizer unit 200 and the housing 100, the atomizer unit 200 can be detachably fixed and inserted into the mounting groove 103 by means of magnetic attraction, or can be detachably fixed and inserted into the mounting groove 103 by means of a buckle 105 connection. Figure 3As shown, one of the outer wall of the atomizing unit 200 and the groove wall of the installation groove 103 is provided with a buckle 105, and the other is provided with a slot 204 corresponding to the buckle 105, and the buckle 105 is engaged in the slot 204, so that the atomizing unit 200 can be fixedly inserted in the installation groove 103. Compared with the magnetic fixing method, it can avoid the atomizing unit 200 being difficult to disassemble due to too strong magnetism, and it can also avoid the atomizing unit 200 being easy to fall off from the installation groove 103 due to insufficient magnetism. At the same time, it can avoid the problems of increased cost and increased device volume caused by setting a magnetic structure, so it has better technical effects.

[0042] In this way, when the atomizing medium in the atomizing unit 200 is exhausted or the atomizing unit 200 fails, the user can easily replace the atomizing unit 200, so it is convenient for the user to use it, and it can also reduce the risk of the whole machine being scrapped due to local damage to electronic components, extend the life of the product, and reduce environmental pollution and waste of resources. Furthermore, since the installation groove 103 runs through the opposite sides of the shell 100, when the user removes the atomizing unit 200, he only needs to use his fingers to push the atomizing unit 200 along the axial direction of the installation groove 103, and the atomizing unit 200 can be easily removed from the shell 100, which is convenient for the user's operation and greatly improves the user's experience.

[0043] Furthermore, in order to prevent the user from inserting the atomizing unit 200 into the mounting groove 103 in the reverse direction, that is, to ensure that the atomizing unit 200 can only be inserted into the mounting groove 103 at one of the two ends of the mounting groove 103 along its own axial direction,

[0044] The two ends of the mounting groove 103 in its axial direction are respectively defined as a limit end and a mounting end, and the inner diameter of the opening of the mounting end is larger than the inner diameter of the opening of the limit end, so that the atomization unit 200 can only be inserted into the mounting groove 103 from the mounting end, thereby preventing the atomization unit from being inserted in the reverse direction.

[0045] Exemplarily, a limiting structure extending toward the mounting groove may be provided at the opening edge of the limiting end, such as a protrusion or rib extending from the opening edge of the limiting end toward the center of the mounting groove 103; the inner circumferential surface of the mounting groove 103 may also be provided as a structure extending obliquely along the axial direction of the mounting groove 103, both of which can achieve that the inner diameter of the opening of the mounting end is larger than the inner diameter of the opening of the limiting end, which is not limited here.

[0046] Furthermore, in order to prevent the atomization unit 200 from rotating and thus being misaligned when inserted into the mounting groove 103, the outer circumferential surface of the atomization unit 200 includes a first plane 205, and the air hole 202 is opened on the first plane 205. Correspondingly, the groove wall of the mounting groove 103 includes a second plane 103a that is in contact with the first plane 205, and the air hole 102 is opened on the second plane 103a. The groove wall contour of the mounting groove 103 matches the outer circumferential surface contour of the portion of the atomization unit 200 inserted in the mounting groove 103. In the embodiment shown in the figure, the outer peripheral surface of the part of the atomization unit 200 inserted into the mounting groove 103 has a plane, namely the first plane 205, and the rest are arc surfaces. Correspondingly, the groove wall of the mounting groove 103 also has a plane, namely the second plane 103a, and the rest are also arc surfaces. When the atomization unit 200 is inserted into the mounting groove 103, there is only one installation direction in its own circumferential direction, thereby avoiding the atomization unit 200 from rotating and causing dislocation when inserted into the mounting groove 103.

[0047] Of course, it is understandable that the groove wall contour of the mounting groove 103 and the outer peripheral surface contour of the part of the atomization unit 200 inserted in the mounting groove 103 are not limited to the shapes shown in the embodiment of the figure, as long as they have a plane so that the atomization unit 200 cannot rotate after being inserted into the mounting groove 103.

[0048] Please continue reading Figure 4 and Figure 5 In the embodiment shown in the figure, the power supply unit 300 includes a battery 310 and a circuit board 320. The battery 310 is disposed on one side of the circuit board 320 and is electrically connected to the circuit board 320. The circuit board 320 is sleeved and clamped on the outer wall of the mounting groove 103 to be fixed in the accommodating cavity of the housing 100. Figure 5 As shown, at least two electrodes 321 are provided on the circuit board 320. Figure 6 As shown, the first plane 205 of the atomization unit 200 has at least two electrode contacts 206 correspondingly, and each electrode 321 is electrically connected to a corresponding electrode contact 206. In the present embodiment, there are three electrodes 321, and there are also three electrode contacts 206 correspondingly. Each electrode 321 abuts against a corresponding electrode contact 206, thereby realizing electrical connection between the power supply unit 300 and the atomization unit 200, and by arranging the electrode contact 206 on the first plane 205, the electrode 321 can be more tightly abutted against the electrode contact 206, thereby avoiding the occurrence of poor contact.

[0049] It should be noted that among all the electrodes 321, one electrode 321 is a positive electrode, another electrode 321 is a negative electrode, and the remaining electrodes 321 can be used for information reading, writing, collection, and interaction between the atomization unit 200 and the power supply unit 300. For example, in this embodiment, there are three electrodes 321, and except for the two electrodes 321 used as the positive electrode and the negative electrode, the remaining electrode 321 can be used to read the information in the chip, circuit or sampling resistor in the atomization unit 200, so that the circuit board 320 in the power supply unit 300 can match different heating modes according to different atomization units 200 control.

[0050] It should be noted that the aerosol generating device 10 provided in the present application may not be provided with the power supply unit 300, and the atomization unit 200 may be powered by an external power supply, which is not limited here.

[0051] See also Figure 4 and Figure 7 In terms of the specific structure of the atomization unit 200, the atomization unit 200 includes a tool box 210, a heating pot 220 and an atomization core 230. The tool box 210 is coaxially inserted into the mounting groove 103, the heating pot 220 is coaxially arranged in the tool box 210, and the atomization core 230 is arranged in the heating pot 220. The heating pot 220 is a hollow cylindrical metal structure, which includes a first pot body 221 and a second pot body 222 which are coaxially connected and have different diameters. The diameter of the first pot body 221 is smaller than the diameter of the second pot body 222. A first cavity 221a is opened in the first pot body 221, a second cavity 222a is opened in the second pot body 222, and the atomization core 230 is arranged in the first cavity 221a. When the atomizer core 230 is powered on to generate heat, the solid atomization medium (eg, solid tobacco paste) contained in the second cavity 222a can be melted into a molten state and flow into the atomizer core 230, and can be further heated by the atomizer core 230 to generate aerosol.

[0052] Furthermore, in order to accelerate the melting of the solid atomizing medium into a molten state, on the basis of the above embodiment, the outer peripheral surface of the second pot body 222 is provided with a preheating element (not shown in the figure) electrically connected to the circuit board 320 of the power supply unit 300. The preheating element is used to preheat the atomizing medium contained in the second cavity 222a, so that the solid atomizing medium is accelerated to melt and flow into the atomizing core 230, so that the atomizing core 230 can more fully heat the atomizing medium to generate an aerosol.

[0053] Furthermore, the atomizing unit 200 further includes a sealing ring 240, which is used to seal the atomizing medium and parts in the atomizing unit 200, and is also used to further prevent the condensate in the main airway 401 from flowing back into the atomizing chamber 203. In the connection structure between the tool box 210 and the sealing ring 240, the sealing ring 240 is at least partially coaxially inserted in the tool box 210. In the embodiment shown in the figure, the sealing ring 240 is completely inserted in the tool box 210, the heating pot 220 is coaxially inserted in the sealing ring 240, the inner wall of the sealing ring 240 and part of the inner wall of the tool box 210 jointly form the atomizing chamber 203, and the tool box 210 is provided with an air inlet 201 and an air vent 202, and the air inlet 201 and the air vent 202 are connected to each other through the atomizing chamber 203. At this time, the seal between the atomizer unit 200 and the shell 100 is achieved by the second seal 600. In this embodiment, the air hole 102 is opened on the second seal 600 and passes through the opposite sides of the second seal 600. The second seal 600 forms a part of the groove wall of the mounting groove 103. The end of the airway tube 400 away from the suction nozzle 104 is inserted into the air hole 102 opened by the second seal 600. When the atomizer unit 200 is inserted into the mounting groove 103, one side of the second seal 600 abuts against the device box 210 of the atomizer unit 200, so that the air hole 102 and the vent hole 202 are connected to each other.

[0054] Preferably, the air inlet 201 is disposed on the back side of the tool box 210 (the side facing the heating pot 220 is the front side). Specifically, the flow direction of the air at the air inlet 201 entering the atomizing chamber 203 is parallel to the axial direction of the mounting slot 103 .

[0055] In other embodiments, the air inlet 201 may also be provided on the side of the device box 210, and when the atomizing unit 200 is located in the mounting groove 103, the air inlet 201 faces the side wall of the mounting groove 103. At this time, the external air may flow to the air inlet 201 through the gap between the atomizing unit 200 and the mounting groove 103, and then flow through the inside of the atomizing unit 200. Of course, another through hole may be provided at the position of the side wall of the mounting groove 103 corresponding to the air inlet 201, so as to allow the external air to enter the atomizing chamber 203.

[0056] See also Figure 4 and Figure 7In order to facilitate the placement of the atomized medium into the heating pot 220, one end of the atomizing unit 200 has an opening 207, and the opening 207 faces the second cavity 222a of the heating pot 220, so that the atomized medium can be placed into the second cavity 222a of the heating pot 220 from the opening 207. An oil tank cover 250 for closing the opening 207 is detachably provided at the position of the opening 207. When the aerosol generating device 10 needs to load the atomized medium into the heating pot 220 before leaving the factory, it only needs to open the oil tank cover 250, load the solid atomized medium into the accommodating cavity of the heating pot 220 through the opening 207, and then close the oil tank cover 250.

[0057] Preferably, if Figure 4 As shown, the central axis of the heating pot 220 is perpendicular to the central axis of the airway tube 400 (i.e., the central axis of the mounting groove 103 is perpendicular to the central axis of the main airway 401). In this way, when the aerosol generating device 10 is held by the user for horizontal inhalation (i.e., when the opening 207 of the atomization unit 200 is facing upward), the solid atomization medium is converted into a molten state that can flow under the preheating action of the preheating member, and the molten atomization medium is further heated by the atomization core 230 to generate an aerosol, so that the flow path of the molten atomization medium is in a vertical direction, and the outflow path of the aerosol is in a horizontal direction. In this case, the molten atomization medium can enter the atomization core 230 more smoothly under the action of gravity, so that the atomization medium can be atomized more thoroughly when heated and atomized by the atomization core 230, thereby reducing the residue of the atomization medium and avoiding the blockage of the main airway 401. Moreover, through the above arrangement, the power supply unit 300 can be arranged by fully utilizing the space inside the shell 100 in the flow direction of the atomized medium, so that the internal structure of the aerosol generating device 10 is more compact, thereby achieving the purpose of making the appearance of the aerosol generating device 10 smaller and flatter.

[0058] In addition, in order to enable the user to conveniently control the working state of the aerosol generating device 10, that is, to conveniently control the aerosol generating device 10 to switch from the preheating state to the heating state, and from the heating state to the standby state in which the aerosol generating device 10 is not working, as shown in Figure 2, the shell 100 is also provided with a button 800 on the side of the opening 207 facing away from the atomization unit 200 for the user to switch between the above-mentioned working states. The button 800 can move relative to the shell 100 under the action of external force, so that the button 800 can be connected to the circuit board 320, thereby driving the circuit board 320 in turn to respectively control the opening and closing of the preheating part and the opening and closing of the atomization core 230.

[0059] In this way, by arranging the opening 207 of the atomization unit 200 relative to the button 800, the aerosol generating device 10 provided in the present application is more user-friendly in design, and the user's operation is more in line with people's operating habits. During operation, the user only needs to hold the shell 100 with his hand, press the button 800 with his thumb, or toggle the button 800 to easily control the aerosol generating device 10 to be in a heating state, a preheating state or a standby state. Compared with the button 800 being arranged on the same side as the opening 207 of the atomization unit 200 or being arranged on the side relative to the opening 207 of the atomization unit 200, it is more suitable for user operation. Furthermore, by using the button 800 to control the aerosol generating device 10 to switch between the standby state, the preheating state, and the heating state, it is not necessary to set an airflow sensor in the atomization unit 200. The user can only drive the battery 310 to power the atomization unit 200 when applying force to the button 800. When no force is applied to the button 800, the battery 310 cannot power the atomization unit 200 and start the atomization unit 200, so that the user can use the above-mentioned aerosol generating device 10 to control more accurately when inhaling than using an airflow sensor, and reduce the occurrence of dry burning caused by false triggering. Furthermore, because there is no need to set an airflow sensor, the structure of the atomization unit 200 is simple, and there is no need to set an auxiliary airway connected to the airflow sensor and connected to the main airway 401, which also avoids the aerosol remaining in the auxiliary airway after atomization, so that the more expensive solid atomization medium can be fully atomized and inhaled, reducing unnecessary waste of atomization medium.

[0060] The paste atomizing device of the above embodiment has the following operating steps:

[0061] In the first step, the button 800 is pressed once, and the driving circuit board 320 controls the preheating element to preheat the heating pot 220 for at least 5 seconds, so that the solid atomizing medium in the heating pot 220 melts to form a fluid atomizing medium and penetrates into the atomizing core 230 .

[0062] In the second step, the user continues to press the button 800 and inhales from the air outlet 101; the driving circuit board 320 controls the atomizer core 230 to work, and when the atomizer core 230 works, the molten atomizing medium flowing into the inside is further heated to produce aerosol for the user to inhale.

[0063] In the third step, the user releases the button 800 and stops inhaling, completing one inhalation action, and the atomizing core 230 also stops working, and the aerosol generating device 10 enters the standby state. When the user needs to inhale again, the second and third steps can be repeated.

[0064] Finally, it should be noted that the various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various technical features in the above-described 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.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
