[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] Reference Figures 1 to 7The diagram illustrates an embodiment of the exhaust structure of the present invention. The exhaust structure includes an oil storage tank 100, a heating element 200, and an atomizing bracket 300. The atomizing bracket 300 is fixedly connected to the oil storage tank 100. The atomizing bracket 300 includes a first channel 310 and multiple receiving cavities 320. Each receiving cavity 320 communicates with the oil storage tank 100, and one end of each receiving cavity 320 communicates with the first channel 310. The heating element 200 is disposed within each receiving cavity 320.

[0031] Specifically, the oil storage tank 100 is provided to store the aerosol matrix; the atomizing bracket 300 is fixedly connected to the oil storage tank 100, and a plurality of receiving cavities 320 are provided on the atomizing bracket 300. The receiving cavities 320 are used to accommodate the heating element 200. The heating element 200 can heat the aerosol matrix to generate aerosol. Therefore, the heating element 200 is provided on each receiving cavity 320. The heating elements 200 on each receiving cavity 320 are connected in series. When the aerosol generating device starts to work, each heating element 200 can work simultaneously and generate aerosol at the same time. Since the receiving cavity 320 is connected to the oil storage tank 100, the aerosol matrix stored in the oil storage tank 100 flows to the receiving cavity 320 and comes into contact with the heating element 200 located in the receiving cavity 320 to undergo an atomization reaction and generate aerosol. The atomizing bracket 300 is provided with a first channel 310, which is a flow channel for aerosol. Each receiving cavity 320 is connected to the first channel 310. Therefore, all the aerosol generated simultaneously in each receiving cavity 320 is collected in the first channel 310, and finally a large amount of aerosol is sucked out. This achieves a one-time increase in aerosol suction volume, meeting the user's need to suction a large amount of aerosol at once. The exhaust structure is simple, has low production cost, and does not require the selection of a heating element 200 with a specific resistance value, thus meeting the user's needs and avoiding problems such as wicking, poor oil guiding, and carbon buildup caused by the heating element 200 having too low a resistance value.

[0032] In one embodiment, reference is made to Figures 1 to 2As shown, multiple receiving cavities 320 are located on the same plane and opened along a direction perpendicular to the first channel 310, and the multiple receiving cavities 320 are interconnected at the first channel 310. Specifically, since all the receiving cavities 320 are connected to the first channel 310 and are arranged on the same horizontal plane perpendicular to the first channel 310, the exhaust structure is more compact and easier to install. Furthermore, the aerosol generated by each receiving cavity 320 flows to the first channel 310 at the same time and then flows to the outside at the same time, allowing the user to extract a large amount of aerosol at once. This avoids the situation where the amount of aerosol extracted is small at the beginning of extraction due to the different times the aerosol from each receiving cavity 320 reaches the first channel 310. This structure further increases the probability of the user extracting a large amount of aerosol at once. Meanwhile, the port at one end of the receiving cavity 320 that is connected to the first channel 310 is smaller than the opening at the other end of the receiving cavity 320. The receiving cavity 320 extends from the end connected to the first channel 310 away from the first channel 310 and gradually widens outward. This structure allows the atomizing bracket 300 to be provided with multiple receiving cavities 320, saving the space occupied by the exhaust structure and providing multiple receiving cavities 320 to the maximum extent.

[0033] In a specific embodiment, refer to Figure 1 As shown, the receiving cavity 320 is provided with a first oil storage component 321, the first oil storage component 321 is provided with a through groove, and the heating element 200 is provided in the through groove. Specifically, each of the receiving cavities 320 is provided with a first oil storage component 321. The first oil storage component 321 is used to store the aerosol matrix flowing from the oil storage tank 100 to the receiving cavity 320, so that the aerosol matrix is ​​not stored in the receiving cavity 320 in a flowing state, reducing the risk of aerosol matrix leakage. At the same time, the first oil storage component 321 can store more aerosol matrix, further avoiding aerosol matrix leakage. In addition, the first oil storage component 321 is provided with a through groove perpendicular to the first channel 310, so that the heating element 200 is closely attached to the first oil storage component 321, increasing the contact area between the heating element 200 and the first oil storage component 321. Furthermore, the heating element 200 is set with a mesh structure, further increasing the contact area between the heating element 200 and the first oil storage component 321, thereby improving the atomization efficiency of the heating element 200 and the aerosol matrix, and ultimately generating more aerosol at one time.

[0034] In one embodiment, reference is made to Figure 1 and Figure 2As shown, the side wall of the receiving cavity 320 is provided with a through hole 322, which connects the receiving cavity 320 and the oil storage tank 100. Specifically, multiple through holes 322 are provided on the side wall of the receiving cavity 320. In this embodiment, through holes 322 are provided on the upper side wall, left side wall and right side wall of the receiving cavity 320. The through holes 322 connect the receiving cavity 320 and the oil storage tank 100, so that the aerosol matrix in the oil storage tank 100 can flow through the through holes 322 to the receiving cavity 320 and be stored in the first oil storage component 321. The through holes 322 improve the flow efficiency of the aerosol matrix, thereby improving the reaction efficiency between the aerosol matrix and the heating element 200, and generating a large amount of aerosol more quickly.

[0035] In a specific embodiment, refer to Figures 3 to 7 As shown, the exhaust structure also includes a second oil storage component 400, which is disposed in the oil storage chamber 100 and sleeved on the outside of the atomizing bracket 300. Specifically, the second oil storage component 400 is located in the oil storage chamber 100. The second oil storage component 400 is used to store the aerosol matrix located in the oil storage chamber 100. In this embodiment, the second oil storage component 400 adopts a venting type oil storage cotton, so that the internal airflow of the second oil storage component 400 is consistent with the air pressure of the external airflow, reducing the risk of aerosol matrix leakage. The size of the second oil storage component 400 is adapted to the oil storage chamber 100. Using the second oil storage component 400 can further avoid aerosol matrix leakage and maximize the utilization of aerosol matrix. The second oil storage component 400 is sleeved on the outside of the atomizing bracket 300, so more aerosol matrix on the second oil storage component 400 can flow into the receiving cavity 320 of the atomizing bracket 300, improving the generation efficiency of the heating element 200 and the aerosol matrix. At the same time, the structure is compact, saves space of the venting structure, and is easy to install.

[0036] In one embodiment, reference is made to Figure 6As shown, the exhaust structure also includes a nozzle 500, and the second oil storage component 400 further includes a second channel 410. One end of the second channel 410 is connected to the first channel 310, and the second channel 410 connects the first channel 310 and the nozzle 500. Specifically, the aerosol generator includes a housing 619, which is provided with the nozzle 500. In the middle part of the second oil storage component 400, a second channel 410 is provided along the axial direction of the second oil storage component 400. Since the second oil storage component 400 is sleeved on the outside of the atomizing bracket 300, the length of the first channel 310 is less than the length of the second channel 410, and the first channel 310 is embedded in one end of the second channel 410. The first channel 310 and the second channel 410 are in communication, and the other end of the second channel 410 is also connected to the... The aerosol generated by the receiving cavity 320 is gathered in the first channel 310 and then flows to the second channel 410. Finally, it flows to the mouthpiece 500 and into the user's mouth. This structure further reduces the production cost of the exhaust structure and facilitates the installation of the atomizing bracket 300 and the second oil storage component 400. The length of the second channel 410 is longer than that of the first channel 310, which ensures airflow while also keeping the air pressure of the second oil storage component 400 consistent with the external air pressure, thus preventing leakage of the aerosol matrix.

[0037] In a specific embodiment, refer to Figure 3As shown, the second oil storage component 400 further includes a receiving groove 420, which is correspondingly disposed with the receiving cavity 320. The receiving cavity 320 is located in the receiving groove 420. The receiving groove 420 has an opening at one end away from the first channel 310, and the heating element 200 passes through the opening and connects to the circuit board 615. Specifically, the second oil storage component 400 has the same number of receiving grooves 420 as the receiving cavity 320, and the positions of the receiving grooves 420 and the receiving cavity 320 are corresponding. The receiving cavity 320 is installed in the receiving groove 420, and the receiving cavity 320 and the receiving groove 420 are tightly combined, which improves the fixation of the second oil storage component 400 and the atomizing bracket 300, making it less likely for the atomizing bracket 300 to detach from the second oil storage component 400. At the same time, it allows the aerosol matrix on the second oil storage component 400 to enter the receiving cavity 320 more quickly. An opening is provided at one end of the receiving groove 420 away from the first channel 310, so that one end of the heating element 200 can pass through the opening and connect to the circuit board 615, thereby controlling the working state of the heating element 200. In this embodiment, the heating element 200 is a heating wire. Therefore, the opening makes the connection between the heating element 200 and the circuit board 615 simpler, and the internal structure of the exhaust structure is simpler. There will be no phenomenon of cross-entanglement between the heating elements 200 in each receiving cavity 320, ensuring the stability of the internal structure of the exhaust structure.

[0038] In one embodiment, reference is made to Figure 6 As shown, the mouthpiece 500 includes a third channel 510. The third channel 510 extends from one end connected to the second channel 410 away from the atomizing support 300, and the diameter of the third channel 510 gradually increases from the end near the second channel 410 towards the top of the mouthpiece 500. Specifically, the third channel 510 is provided inside the mouthpiece 500, and the third channel 510 is connected to the second channel 410. The third channel 510 extends all the way to the top of the mouthpiece 500 and connects to the outside. The diameter of the third channel 510 gradually increases from the end near the second channel 410 upwards, that is, the third channel 510 is an unclosed inverted cone structure. This structure allows aerosol to flow quickly to the third channel 510 and converge there. When the user inhales, a large amount of aerosol can be drawn in, further meeting the user's needs. Moreover, the aerosol flowing to the third channel 510 will not flow into the user's mouth all at once, thus preventing choking.

[0039] Reference Figures 1 to 7As shown, the atomizing bracket 300 has four receiving cavities 320. The four receiving cavities 320 are arranged opposite each other and are all connected to the first channel 310. The openings of the four receiving cavities 320 are opened in a direction away from the first channel 310. Specifically, in this embodiment, four receiving cavities 320 are provided on the atomizing bracket 300. The four receiving cavities 320 are respectively located on the front, rear, left, and right sides of the first channel 310. The planes where the four receiving cavities 320 are located are parallel to and do not overlap with the planes where the ports of the first channel 310 are located. The heating element 200 is placed in the four receiving cavities 320. Therefore, the exhaust structure has four heating elements 200. When the resistance of the heating element 200 is 1.2 ohms, the total amount of aerosol generated by the atomization of the four heating elements 200 and the aerosol matrix can reach the amount of aerosol generated by the atomization of a single heating element 200 with a resistance of 0.2 ohms and the aerosol matrix. This exhaust structure can solve the user's need for a large amount of aerosol in a disposable aerosol generator. Even when a high-resistance heating element 200 is selected, it can still generate a sufficient amount of aerosol. The openings of the four receiving cavities 320 are opened in a direction away from the first channel 310, so that one end of the heating element 200 can come out from the opening of the receiving cavity 320 and connect to the circuit board 615. The structure is simple, the production cost is low, and it can increase the aerosol suction volume at one time, meeting the user's need to suction a large amount of aerosol at one time. It does not require the selection of a heating element 200 with a specific resistance value to meet the user's needs, and avoids problems such as wicking, poor oil guiding, and carbon buildup caused by the heating element 200 having too low a resistance value.

[0040] Reference Figure 6 and Figure 7 As shown, this embodiment also provides an aerosol generating device, which includes an exhaust structure. The exhaust structure can be any exhaust structure provided by this invention. Since the specific structure and working principle of the exhaust structure have been described in detail in the previous specification, they will not be repeated here for the sake of brevity.

[0041] The aerosol generator in this embodiment utilizes the exhaust structure provided by this invention to increase the aerosol extraction volume at one time, meeting the user's need to extract a large amount of aerosol at once. Furthermore, its simple structure and low production cost eliminate the need for a heating element 200 with a specific resistance value, thus meeting user requirements and avoiding problems such as wicking, poor oil guiding, and carbon buildup caused by an excessively low resistance value of the heating element 200. Simultaneously, the use of the first oil storage component 321 and the second oil storage component 400 ensures that the internal airflow of the aerosol generator maintains the same pressure as the external airflow, and prevents the aerosol matrix from being in constant contact with the heating element 200, thereby avoiding the risk of aerosol matrix leakage.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
