[0038] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the atomization device 10 involved in the embodiment of the present application includes: an atomization tube 100, a heating component 200, a liquid suction component 300 and an air guide tube 400.

[0039] Specifically, the atomizing tube 100 is provided with an atomizing channel 110 extending along the airflow direction, and a liquid guide hole 120 and an observation window 130 are also provided on the tube wall of the atomizing tube 100, and the liquid guide hole 120 and the observation window 130 are both connected to the atomizing channel 110; the heating component 200 is arranged in the atomizing channel 110; the liquid absorption component 300 is installed in the atomizing channel 110 and is located at the periphery of the heating component 200, and the liquid absorption component 300 is at least partially opposite to the liquid guide hole 120; and an air guide tube 400, one end of which is arranged in the atomizing channel 110 and is located within the observation range of the observation window 130.

[0040] It should be noted that the airflow direction is Figure 1 The direction that x points to.

[0041] In the above-mentioned atomization device 10, since the atomization channel 110 of the atomization tube 100 is connected to the liquid guide hole 120 on the tube wall of the atomization tube 100, the aerosol matrix can enter the atomization channel 110 through the liquid guide hole 120. Since the liquid absorption component 300 is at least partially opposite to the liquid guide hole 120 and is located at the periphery of the heating component 200, the aerosol matrix can enter the atomization channel 110 through the liquid guide hole 120 and be absorbed by the liquid absorption component 300, and is heated by the heating component 200 to achieve atomization. In this process, the air guide tube 400 is used to guide the atomized gas generated by the atomizer tube 100. Since one end of the air guide tube 400 is arranged in the atomizer channel 110 and is located within the observation range of the observation window 130, during the assembly process of the above-mentioned atomizer device 10, the position of one end of the air guide tube 400 arranged in the atomizer channel 110 can be observed through the observation window 130 to ensure that the air guide tube 400 can be accurately installed in place to ensure the atomization effect.

[0042] Specifically, in the above-mentioned embodiments, the sealed connection between the air guide tube 400 and the atomizer tube 100 can be achieved by forming an interference fit between the air guide tube 400 and the liquid suction piece 300, or by providing a sealing piece between the air guide tube 400 and the liquid suction piece 300 to achieve the sealed connection between the air guide tube 400 and the atomizer tube 100, or by the abutment between the air guide tube 400 and the liquid suction piece 300 to achieve the sealed connection between the air guide tube 400 and the atomizer tube 100.

[0043] Reference Figure 4 As shown, the atomizer tube 100 is also provided with a liquid guide notch 140 connected to the atomizer channel 110, and the liquid absorption member 300 has a first liquid absorption portion 310 and a second liquid absorption portion 320 connected to each other, the first liquid absorption portion 310 is wrapped around the outside of the heating component 200, and the free end of the second liquid absorption portion 320 extends out of the liquid guide notch 140, the air guide tube 400 is in contact with the first liquid absorption portion 310, and the abutment between the air guide tube 400 and the liquid absorption member 300 is located within the observation range of the observation window 130.

[0044] It can be understood that, since the first liquid absorbing portion 310 is wrapped around the outside of the heating component 200, and the free end of the second liquid absorbing portion 320 extends out of the liquid guiding notch 140, the second liquid absorbing portion 320 can be limited by the liquid guiding notch 140, and the liquid absorbing member 300 can be further limited by the liquid guiding notch 140, so that the liquid absorbing member 300 is fixedly installed on the atomizing tube 100, and the liquid absorbing member 300 is prevented from moving relative to the atomizing tube 100 along the airflow direction, so as to reduce the assembly difficulty of the above-mentioned atomizing device 10. At the same time, the above-mentioned guide notch 140 can be used to limit the position of the second liquid absorbing portion 320. The air tube 400 is in contact with the first liquid absorption part 310. Therefore, the air tube 400 and the first liquid absorption part 310 can be abutted against each other to seal the flow path of the aerosol and prevent the atomized gas from flowing out of the air tube 400, so as to improve the utilization rate of the aerosol matrix and the user experience. At the same time, it can prevent the aerosol matrix from flowing into the atomization channel from the liquid guide notch 140 and causing leakage. Furthermore, it can prevent the air tube 400 from being inserted into the liquid absorption part 300 and interfering with the heating component 200 wrapped in the first liquid absorption part 310.

[0045] Reference Figure 1 As shown, the atomization device 10 also includes a liquid storage part 500, and an avoidance channel 510 extending along the airflow direction and a slit 520 connected to the avoidance channel are opened inside the liquid storage part 500. The atomization tube 100 and the air guide tube 400 are both arranged in the avoidance channel 510, and the free end of the second liquid suction part 320 extends out of the liquid guide notch 140 and is located in the slit 520.

[0046] In the above-mentioned embodiment, the liquid storage element 500 is used to store the aerosol matrix.

[0047] It can be understood that since the free end of the second liquid absorption portion 320 extends out of the liquid guiding notch 140 and is located in the slit 520, the second liquid absorption portion 320 can be fixed in the slit 520, and the second liquid absorption portion 320 can contact the liquid storage part 500 to absorb the aerosol matrix inside the liquid storage part 500, and the aerosol matrix can be diffused to the first liquid absorption portion 310, and the aerosol matrix on the first liquid absorption portion 310 is heated by the heating component 200 to achieve atomization of the aerosol matrix. In this process, the rate at which the aerosol matrix flows to the first liquid absorption portion 310 can be increased by the second liquid absorption portion 320.

[0048] Reference Figure 3 As shown, the liquid guiding gap 140 is opened at one end of the atomizing tube 100 close to the air guiding tube 400 , and the end of the liquid guiding gap 140 away from the air guiding tube 400 has a limiting wall 141 , and the end of the second liquid suction part 320 away from the air guiding tube 400 abuts against the limiting wall 141 .

[0049] It can be understood that since the second liquid absorption part 320 is inserted into the liquid guiding notch 140 and the end of the second liquid absorption part 320 away from the air guiding tube 400 is abutted against the limiting wall 141, the limiting wall 141 of the liquid guiding notch 140 can limit the second liquid absorption part 320, and further limit the liquid absorption component, so as to facilitate the positioning of the first liquid absorption part 310 in the atomization channel 110, facilitate the installation of the liquid absorption component, and further reduce the assembly difficulty of the above-mentioned atomization device 10.

[0050] Reference Figure 4 As shown, the end surface of the first liquid suction part 310 close to the air guide tube 400 is flush with the end surface of the second liquid suction part 320 close to the air guide tube 400 , and the air guide tube 400 abuts against the first liquid suction part 310 and the second liquid suction part 320 .

[0051] It can be understood that, since the end surface of the first liquid absorbing part 310 close to the air guide tube 400 and the end surface of the second liquid absorbing part 320 close to the air guide tube 400 are flush, the aerosol matrix on the second liquid absorbing part 320 can first diffuse to the downstream end of the first liquid absorbing part 310, and then flow from the downstream end of the first liquid absorbing part 310 to the upstream end of the first liquid absorbing part 310 through gravity and capillary action, so that the first liquid absorbing part 310 is infiltrated with the aerosol matrix at all locations along the axial direction of the atomization tube 100. Further, since the air guide tube 400 is simultaneously in contact with the first liquid absorbing part 310 and the second liquid absorbing part 320, the connection sealing between the air guide tube and the liquid absorbing member 300 can be further improved.

[0052] Reference Figure 2 as well as Figure 4 As shown, the liquid absorbent member 300 has two second liquid absorbent portions 320 , the first liquid absorbent portion 310 is wound around the heating component 200 , the two second liquid absorbent portions 320 are respectively connected to the two ends of the first liquid absorbent portion 310 in the circumferential direction, and the two second liquid absorbent portions 320 are attached to each other.

[0053] In one embodiment, the liquid absorbent member 300 is a flexible sheet structure, such as liquid absorbent cotton. The first liquid absorbent portion 310 and the two second liquid absorbent portions 320 are integrally formed to form a liquid absorbent member 300 wound around the heating element. In the airflow direction, the first liquid absorbent portion 310 is longer than the second liquid absorbent portion 320, that is, in addition to the portion connected to the second liquid absorbent portion 320, the first liquid absorbent portion 310 also includes a portion located upstream of the second liquid absorbent portion 320 in the airflow direction (such as Figure 1 After the liquid absorbing member 300 is wrapped around the heating element, the portion of the first liquid absorbing portion 310 located upstream of the second liquid absorbing portion 320 forms a complete cylindrical shape, and the portion of the first liquid absorbing portion 310 connected to the second liquid absorbing portion 320 forms a complete cylindrical shape with the second liquid absorbing portion 320. In other embodiments, the liquid absorbing member 300 may also be a porous ceramic member.

[0054] It is understandable that when assembling the above-mentioned atomizing device 10, the liquid absorbing member 300 can be first wrapped around the heating component 200 to make the two liquid absorbing parts fit each other, and then the whole composed of the liquid absorbing member 300 and the heating component 200 is installed in the atomizing channel 110, and the free ends of the two liquid absorbing parts are extended out of the liquid guiding notch 140; or the liquid absorbing member 300 can be firstly rolled up so that the two liquid absorbing parts fit each other, and then the liquid absorbing member 300 is installed in the atomizing channel 110, and the free ends of the two liquid absorbing parts are extended out of the liquid guiding notch 140, and finally the heating component 200 is inserted into the wrapped space formed by the winding of the liquid absorbing member 300 to form the wrapping of the heating component 200 by the liquid absorbing member 300. In the assembly process of the above-mentioned atomizing device 10, the wrapping of the heating component 200 by the liquid absorbing member 300 can simplify the assembly process of the above-mentioned atomizing device 10, and reduce the assembly difficulty of the above-mentioned atomizing device 10.

[0055] Reference Figure 4 as well as Figure 5 As shown, the heating component 200 includes a plurality of heating elements and a plurality of electrical connectors, the plurality of heating elements are arranged along the airflow direction, and at least one electrical connector is electrically connected to the plurality of heating elements at the same time. The heating element 200 is electrically connected to the power supply component (not shown) of the aerosol generating device through each electrical connector, so that the power supply component and the heating component 200 form a loop.

[0056] In this way, each heating element can be powered on and heated through multiple electrical connectors, so that each heating element can heat and atomize the aerosol matrix on the liquid absorbing element 300. At the same time, when each heating element is powered on, multiple heating elements can be powered on simultaneously or independently to achieve the switching of the heating power of the above-mentioned atomization device 10. It can be understood that since at least one electrical connector is electrically connected to multiple heating elements at the same time, that is, multiple heating elements share one electrical connector, the number of electrical connectors can be saved, and the circuit control of each heating element is also convenient. The electrical connector can also be used as a physical connection structure between the heating elements to integrate at least two heating elements together to simplify the assembly process.

[0057] Continue to refer to Figure 4 as well as Figure 5 As shown, the heating component 200 includes a first heating element 210 and a second heating element 220. The first heating element 210 and the second heating element 220 are longitudinally arranged along the airflow direction, and the first heating element 210 is arranged close to the air duct 400 relative to the second heating element 220. In the airflow direction, the first heating element 210 and the second heating element 220 are both located between the two ends of the first liquid absorption part 310, and the first heating element 210 is arranged opposite to the second liquid absorption part 320.

[0058] It should be noted that in a conventional atomizer 10, for an atomizer 10 having multiple heating elements, it is usually necessary to connect each heating element to a liquid absorbing element 300 so that the aerosol matrix can be absorbed onto the heating element through the liquid absorbing element 300. At the same time, when assembling the atomizer 10, since the liquid absorbing element 300 is often a structural member made of soft materials such as a sponge, there will be assembly difficulties between multiple heating elements, between multiple liquid absorbing elements 300, and between a heating element and a liquid absorbing element 300 during the assembly process.

[0059] It is understandable that the heating power of the above-mentioned atomization device 10 can be switched by simultaneously powering on the first heating element 210 and the second heating element 220 for heating or independently powering on the first heating element 210 and the second heating element 220 for heating, so as to adjust the atomization solubility of the aerosol matrix, thereby increasing the user's usage experience. At the same time, in the airflow direction, since the first heating element 210 and the second heating element 220 are both located between the two ends of the first liquid absorption part 310, when assembling the above-mentioned atomization device 10, it is only necessary to arrange the first heating element 210 and the second heating element 220 in the first liquid absorption part 310 along the airflow direction, that is, the first heating element 210 and the second heating element 220 are both surrounded by the first liquid absorption part 310. In this way, the assembly process of the above-mentioned atomization device 10 will be simplified and the assembly difficulty of the above-mentioned atomization device 10 will be reduced. At the same time, since the first heating element 210 is arranged close to the air guide tube 400 relative to the second heating element 220, and the first heating element 210 is arranged opposite to the second liquid absorption part 320, the aerosol matrix absorbed onto the first liquid absorption part 310 through the second liquid absorption part 320 can flow through the first heating element 210 and the second heating element 220, so as to ensure that the aerosol matrix on the first liquid absorption part 310 covers the surfaces of the first heating element 210 and the second heating element 220 at the same time, so that the first heating element 210 and the second heating element 220 can both play the role of atomizing the aerosol matrix, so that the above-mentioned atomization device 10 has a better atomization effect.

[0060] Specifically, refer to Figure 5 As shown, the heating component 200 includes a first electrical connector 230, a second electrical connector 240 and a third electrical connector 250, and the first electrical connector 230, the second electrical connector 240 and the third electrical connector 250 are arranged at intervals; wherein the first electrical connector 230 is electrically connected to the first heating element 210, the second electrical connector 240 is electrically connected to the second heating element 220, and the third electrical connector 250 is electrically connected to the first heating element 210 and the second heating element 220.

[0061] More specifically, the first electrical connector 230 , the second electrical connector 240 , and the third electrical connector 250 are also electrically connected to the power supply assembly of the aerosol generating device.

[0062] It can be understood that, since the first electrical connector 230 is electrically connected to the first heating element 210, and the third electrical connector 250 is electrically connected to the first heating element 210, an electrical circuit can be formed between the first heating element 210 and the power supply component through the first electrical connector 230 and the third electrical connector 250, so that the first heating element 210 can be powered on and heated, thereby enabling the first heating element 210 to heat and atomize the aerosol matrix on the liquid absorbing element 300. Similarly, since the second electrical connector 240 is electrically connected to the second heating element 220, and the third electrical connector 250 is electrically connected to the second heating element 220, an electrical circuit can be formed between the second heating element 220 and the power supply component through the second electrical connector 240 and the third electrical connector 250, so that the second heating element 220 can be powered on and heated, thereby enabling the second heating element 220 to heat and atomize the aerosol matrix on the liquid absorbing element 300.

[0063] Reference Figure 2 as well as Figure 3 As shown, in one embodiment, a plurality of liquid guide holes 120 are provided on the tube wall of the atomizer tube 100, and the plurality of liquid guide holes 120 are arranged at intervals along the circumference of the atomizer tube 100, and each liquid guide hole 120 is arranged close to an end downstream of the first liquid suction part 310, and the observation window 130 is connected to at least one liquid guide hole 120.

[0064] It can be understood that, since a plurality of liquid guide holes 120 are provided on the tube wall of the atomizer tube 100, and the plurality of liquid guide holes 120 are arranged at intervals along the circumference of the atomizer tube 100, the aerosol matrix can be sucked into the atomization channel 110 along the circumference of the atomizer tube 100 through the plurality of liquid guide holes 120, so that the first liquid absorption part 310 is infiltrated with the aerosol matrix at various locations along the circumference of the atomizer tube 100, so as to increase the rate at which the aerosol matrix flows to the first liquid absorption part 310. Since each liquid guide hole 120 is arranged close to the downstream end of the first liquid absorption part 310, the aerosol matrix entering the first liquid absorption part 310 can flow from the downstream end of the first liquid absorption part 310 to the upstream end of the first liquid absorption part 310 due to the action of gravity, so that the first liquid absorption part 310 is infiltrated with the aerosol matrix at various locations along the axial direction of the atomizer tube 100. Furthermore, since the observation window 130 is in communication with at least one liquid guide hole 120, during the assembly process of the above-mentioned atomizing device 10, the assembly field of view can be expanded. When the air guide tube 400 abuts against the liquid absorbing member 300, the air guide tube 400 provides a squeezing force to the liquid absorbing member 300, so that the liquid absorbing member 300 is compressed along the air flow direction, and the end of the air guide tube 400 abutting against the liquid absorbing member 300 will be exposed in the liquid guide hole 120, so that it is easier to observe whether the air guide tube 400 is installed in place.

[0065] In one embodiment, a plurality of liquid guiding holes 120 are arranged at intervals along the air flow direction, and the observation window 130 is communicated with the liquid guiding hole 120 located most downstream in the air flow direction.

[0066] It can be understood that since the multiple liquid guide holes 120 are arranged at intervals along the airflow direction, the aerosol matrix can be sucked into the atomization channel 110 along the axial direction of the atomization tube 100 through the multiple liquid guide holes 120, and further the first liquid absorption part 310 is infiltrated with the aerosol matrix at all locations along the axial direction of the atomization tube 100.

[0067] Specifically, in other embodiments, the observation window 130 may not be connected to the liquid guide hole 120 .

[0068] Reference Figure 1 As shown, the aerosol generating device designed in the embodiment of the present application includes the above-mentioned atomization device 10.

[0069] In the above-mentioned aerosol generating device, since the above-mentioned atomization device 10 can determine whether the air guide tube 400 is installed in place during the assembly process, it is possible to improve the air leakage phenomenon caused by the air guide tube 400 not being inserted into place in the above-mentioned aerosol generating device, and the interference phenomenon between the air guide tube 400 and the heating component 200 caused by the air guide tube 400 being inserted too deeply, thereby ensuring the atomization effect.
