Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0026] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0027] The heat-not-burn atomization device (hereinafter referred to as the atomization device) generally includes a power supply mechanism and a heat-not-burn atomizer (hereinafter referred to as the atomizer). The atomizer is used to heat the atomized aerosol to form a matrix, and the power supply mechanism is used to provide electrical energy and function control to the atomizer. The aerosol formed after the aerosol-forming matrix is ​​heated and atomized will mostly flow to one side of the mouthpiece when the user inhales. When the user does not inhale or pauses in the middle, the formed aerosol will flow and spread everywhere, and a large part of the aerosol will condense and accumulate in the parts with low temperatures. The condensate formed by the condensation may flow around and pollute the entire atomization device. The atomization device designed in this application mainly aims to improve the structure of the atomizer, collect the condensate by structural design and make it easy to discharge the condensate, avoid the condensate from contaminating or damaging other parts in the atomization device (such as the power supply mechanism), and avoid the presence of the condensate affecting the taste of the aerosol. The specific technical scheme of the atomizer of this application is as follows.

[0028] refer to Figures 1 to 5 The atomizer includes a heating component 100 and a liquid storage tank 200. The heating component 100 is used to heat and atomize the aerosol-forming matrix 400, and the liquid storage tank 200 is used to store condensed liquid.

[0029] The heating assembly 100 includes a heating tube 110 and a heating base 120. The heating tube 110 has a heating cavity 111. The heating tube 110 has a first end 112 and a second end 113 symmetrically arranged along its axis. The first end 112 is used for inserting an aerosol-forming matrix 400 and is accommodated in the heating cavity 111. The heating base 120 is arranged at the second end 113. The heating base 120 is provided with a plurality of air flow holes 121, which are connected to the heating cavity 111. The plurality of air flow holes 121 arranged on the heating base 120 are generally used to guide air circulation. The heating tube 110 is provided with a heating element (not shown in the figure), which can generate heat to heat the air and then use the heated airflow to heat and atomize the aerosol-forming matrix 400.

[0030] The heating element is arranged around the inner wall of the heating tube 110. The heating element can be composed of a plurality of heating wires, and heating is achieved by resistance heating, or it can be composed of a magnetic material and a coil arranged on the magnetic material, and heating is achieved by electromagnetic heating. The heating tube 110 is generally a cylindrical structure, and its axis is a straight line, which can make the aerosol or condensate flow smoothly.

[0031] The liquid storage tank 200 is used to store condensate. The liquid storage tank 200 is arranged on a side of the heating base 120 away from the heating tube 110. The liquid storage tank 200 has a liquid outlet 221, and the liquid outlet 221 is connected to the air flow hole 121, so that the condensate passes through the liquid outlet 221 and the air flow hole 121 in sequence and flows into the heating chamber 111. When a certain amount of condensate is stored, the atomizer or atomizing device is inverted so that the condensate flows back out of the liquid storage tank 200 from the liquid outlet 221, and then the condensate is guided to flow into the heating chamber 111 through the air flow hole 121. The atomizer or atomizing device is continued to be inverted, and the condensate in the heating chamber 111 can be discharged from the heating chamber 111 to the outside of the entire atomizer by gravity, thereby realizing the discharge and treatment of the condensate.

[0032] Since the temperature of heating and atomizing the aerosol-forming matrix 400 is generally 250°C-350°C, a heating element is directly provided on the heating tube 110, and the temperature of the heating tube 110 is relatively high. The heating base 120 is arranged on one side of the heating tube 110, and the two are in contact, and the temperature of the heating base 120 is also relatively high. The liquid storage tank 200 is arranged relatively far away from the heating element, and its temperature is relatively low (compared with the heating tube 110 and the heating base 120). Moreover, since the liquid storage tank 200 is generally made of metal, the aerosol in the entire atomizer will condense into condensate when it encounters the liquid storage tank 200. The presence of the condensate may contaminate or corrode the components in the entire atomization device (including the atomizer and the power supply mechanism). The condensate is collected and processed by using the setting of the liquid storage tank 200, and the air flow hole 121, which is generally used for air circulation, is used as a structure for discharging the condensate, which can simplify the structure of the entire atomizer and reduce the difficulty of modifying the atomizer.

[0033] In order to clean the condensate thoroughly, when the condensate is discharged, the first end 112 of the heating tube 110 can be provided with a liquid absorbent (such as liquid absorbent cotton), and the liquid absorbent is used to absorb the condensate while it is discharged to avoid flowing outside the heating tube 110. The liquid absorbent can also be extended into the heating chamber 111 to clean the condensate. Of course, the heating element can also be turned on when the condensate is discharged, which can increase the speed of condensate discharge.

[0034] It is understandable that when the atomizer is operating normally, the aerosol-forming matrix 400 is inserted from the first end 112 of the heating tube 110. When the condensate is cleaned and discharged, the aerosol-forming matrix 400 can be removed from the heating tube 110 to avoid the condensate from contaminating the aerosol-forming matrix 400.

[0035] It should be further explained that the condensate mentioned herein is a substance produced when the aerosol formed by the aerosol-forming matrix 400 being heated and atomized is cooled, and it can be a thick liquid.

[0036] refer to Figure 5A liquid collecting groove 122 is provided on the side of the heating base 120 away from the heating tube 110. The liquid collecting groove 122 is formed by the surface of the heating base 120 away from the heating tube 110 being concave toward the direction close to the heating tube 110. The liquid collecting groove 122 is used to collect condensed liquid discharged from the liquid outlet 221 and flow into the heating chamber 111 through the air flow hole 121.

[0037] In order to facilitate the collection of condensed liquid and discharge it from the air flow hole 121, the liquid collecting tank 122 includes a main body 1221 and an enclosure 1222 arranged around the main body 1221. The main body 1221 is recessed in the direction close to the heating tube 110 to form a funnel shape. The enclosure 1222 can limit the flow of condensed liquid. The enclosure 1222 cooperates with the recessed main body 1221 to allow the condensed liquid to be concentrated from the outer edge of the main body 1221 to the center.

[0038] In one embodiment, the orthographic projection of the liquid collecting groove 122 along the axial direction of the heating tube 110 at least partially overlaps with the orthographic projection of the air flow hole 121 along the axial direction of the heating tube 110, so that a connected condensate discharge channel can be formed between the liquid collecting groove 122 and the air flow hole 121, so that the condensate can be smoothly discharged from the air flow hole 121 into the heating chamber 111.

[0039] Of course, in other embodiments, the orthographic projection of the liquid collecting groove 122 along the axial direction of the heating tube 110 completely covers the orthographic projection of the air flow hole 121 along the axial direction of the heating tube 110 .

[0040] The heating base 120 extends along the axial direction of the heating tube 110 and is roughly a cylindrical structure. The air flow is provided with multiple, multiple air flow holes 121 are evenly arranged along the cross-section of the heating base 120. The air flow holes 121 are arranged through the heating base 120 along the extension direction of the heating base 120. The axis of the air flow hole 121 is a straight line, so that air or condensate can pass through directly to avoid affecting its flow rate, especially the direct passage of the condensate can reduce residue and make it discharged more cleanly.

[0041] refer to Figures 2 to 4 The liquid storage tank 200 includes a tank body 210 and a sealing cover 220. The sealing cover 220 is arranged on a side of the tank body 210 close to the heating base 120, and is enclosed with the tank body 210 to form a receiving space 230. The receiving space 230 is used to store condensate. A liquid outlet 221 is arranged on the sealing cover 220, and the liquid outlet 221 is used to connect the receiving space 230 with the air flow hole 121.

[0042] Since the condensate is a viscous liquid, there may be residual condensate in the liquid storage bin 200 after long-term use. The bin body 210 and the sealing cover 220 are detachably connected. When necessary, the bin body 210 can be removed for cleaning or washing to thoroughly clean the condensate in the liquid storage bin 200.

[0043] In one embodiment, a guide portion 222 is provided on one side of the sealing cover 220 close to the heating base 120. The guide portion 222 is formed by the surface of the sealing cover 220 close to the heating base 120 protruding toward the direction close to the heating base 120. The shape and size of the guide portion 222 and the liquid collecting tank 122 match. The guide portion 222 is used to guide the condensate to flow to the liquid outlet 221 and flow into the accommodation space 230 through the liquid outlet 221. The guide portion 222 can also guide the air.

[0044] In one embodiment, a liquid channel 223 is further provided on the sealing cover 220, and two ends of the liquid channel 223 are respectively connected to the accommodating space 230 and the liquid outlet 221, and the axis of the liquid channel 223 is arranged at a right angle to the axis of the heating tube 110, so that there is an "L"-shaped condensate flow trajectory between the accommodating space 230 and the liquid outlet 221. The liquid channel 223 is a straight line segment in the "L"-shaped condensate flow trajectory, and the other straight line segment flows from the accommodating space 230 to the liquid channel 223. The design can control the outflow speed of the condensate, so that the condensate flows along the wall of the liquid channel 223 to the main body 1221 of the liquid collecting tank 122, and then flows along the main body 1221 to the air flow hole 121.

[0045] When the condensate is discharged in an inverted manner, due to the existence of the "L"-shaped condensate flow trajectory, when the condensate is reduced, it may affect its flow from the containing space 230 to the liquid channel 223. At this time, the atomizer or atomizing device can be slightly tilted to allow more condensate to be discharged until no condensate is discharged from the heating chamber 111.

[0046] The atomizer further includes a shell 300, which is sleeved on the outside of the heating component 100 and connected to the liquid storage tank 200 at one end. The shell 300 is provided with an air inlet channel 310, and the sealing cover 220 is provided with an air inlet hole 224. The air inlet channel 310, the air inlet hole 224 and the air flow hole 121 are sequentially connected to guide the outside air from the air inlet channel 310 to flow through the air inlet hole 224 and the air flow hole 121 in sequence, and then flow into the heating chamber 111. The air inlet channel 310, the air inlet hole 224 and the air flow hole 121 provide the air required for the atomizer to work, and the air can be used for air conduction heat exchange, etc. Figure 1 , where the direction indicated by the arrow is the direction of air circulation.

[0047] In order to prevent the condensate from flowing to the air inlet 224 and affecting the taste of the aerosol by flowing along the air inlet 224, the air inlet 224 and the liquid outlet 221 are staggered along the circumference of the sealing cover 220. Specifically, the angle between the air inlet 224 and the liquid outlet 221 is 90°.

[0048] Of course, the arrangement of the liquid collecting tank 122 and the enclosing portion 1222 thereof can also block the condensed liquid, thereby preventing the condensed liquid from flowing to the air inlet 224 .

[0049] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
