[0044] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0045] See Figures 1 to 4 As shown, in this embodiment, the atomizer includes a liquid reservoir 100, a base 200, a support 300, an atomizing core 400, and a return cotton 500. The liquid reservoir 100 includes a liquid storage chamber 101 for storing the aerosol matrix. The liquid reservoir 100 also includes a receiving cavity, which is connected to the liquid reservoir 101. One end of the liquid reservoir 100 has an opening. The base 200 is disposed at one end of the liquid reservoir 100, with part of the base 200 located within the receiving cavity through the opening and part located outside the receiving cavity. The base 200 is sealed to the liquid reservoir 100, and an air inlet 211 is provided on the base 200.

[0046] A support 300 is disposed within the receiving cavity of the liquid storage cup 100 and is sealed to the inner wall of the liquid storage cup 100. At opposite ends of the support 300 are respectively provided an inlet hole 301 and a drain hole 302, with the inlet hole 301 connecting the liquid storage cavity 101 and the drain hole 302. An atomizing core 400 is disposed between the support 300 and the base 200 and covers the drain hole 302. The aerosol matrix in the liquid storage cavity 101 can flow sequentially through the inlet hole 301 and the drain hole 302 to the top surface of the atomizing core 400. The atomizing core 400, the liquid storage cup 100, and the base 200 together form the atomizing cavity 102.

[0047] The atomizing core 400 includes a substrate 410 and a heating element 420. The substrate 410 has a liquid-absorbing surface 411 and an atomizing surface 412. The liquid-absorbing surface 411 is the side of the substrate 410 closer to the liquid storage chamber 101, and the atomizing surface 412 is the side of the substrate 410 away from the liquid storage chamber 101. The heating element 420 is disposed on the atomizing surface 412. That is, the top surface of the atomizing core 400 is the liquid-absorbing surface 411, and the bottom surface of the atomizing core 400 is the atomizing surface 412. The substrate 410 can be made of porous materials such as porous ceramics, porous metals, and porous glass to ensure that the aerosol matrix can permeate from the liquid-absorbing surface 411 to the atomizing surface 412. Part of the liquid absorption surface 411 is exposed through the drain hole 302. The aerosol matrix in the liquid storage chamber 101 can flow to the liquid absorption surface 411 through the liquid inlet hole 301 and the drain hole 302, and then permeate to the atomizing surface 412 through the matrix 410, so that the heating element 420 can heat and atomize the aerosol matrix to generate an aerosol located in the atomizing chamber 102 for the user to inhale.

[0048] The return cotton 500 is placed inside the atomizing chamber 102 and in contact with the atomizing core 400. The return cotton 500 can draw the aerosol matrix in the atomizing chamber 102 back to the surface of the atomizing core 400 through capillary action for secondary atomization.

[0049] In some technical solutions, the aerosol matrix stored in the liquid storage chamber 101 above the atomizing core 400 of the atomizer is prone to leaking into the atomizing chamber 102 below the atomizing core 400, reducing the atomization rate of the aerosol matrix.

[0050] In this embodiment, the atomizer includes a liquid storage cup 100, a base 200, a support 300, an atomizing core 400, and a return cotton 500. The liquid storage cup 100 includes a liquid storage chamber 101 for storing the aerosol matrix. The base 200 is disposed at one end of the liquid storage cup 100, and the support 300 is disposed inside the liquid storage cup 100 and sealed to the inner wall of the liquid storage cup 100. The support 300 has an inlet hole 301 and an outlet hole 302 at opposite ends. 301 connects the liquid storage chamber 101 and the drain hole 302. The atomizing core 400 is positioned between the support 300 and the base 200 and covers the drain hole 302. The atomizing core 400, the liquid storage cup 100, and the base 200 together form the atomizing chamber 102. The return cotton 500 is positioned inside the atomizing chamber 102 and in contact with the atomizing core 400. The return cotton 500 can draw the aerosol matrix in the atomizing chamber 102 back to the surface of the atomizing core 400 through capillary action for secondary atomization. This secondary atomization via the return cotton 500 improves the atomization rate of the aerosol matrix and increases the number of suction ports for the user.

[0051] In some embodiments, at least two return cotton 500s are disposed on opposite sides of the atomizing core 400. For example, two return cotton 500s are disposed on opposite sides of the atomizing core 400. It should be understood that one return cotton 500 may be disposed on each side of the atomizing core 400, but is not limited thereto; multiple return cotton 500s may be disposed on each side of the atomizing core 400, depending on the specific circumstances. Furthermore, the number of return cotton 500s on both sides of the atomizing core 400 may be the same or different. A rectangular groove for installing the return cotton 500 may be provided on the side of the support 300 away from the liquid storage chamber 101, with one end of the return cotton 500 disposed in the rectangular groove of the support 300 and the other end of the return cotton 500 extending toward the base 200.

[0052] Multiple return cotton 500s are provided to improve the efficiency of reverse suction of aerosol matrix from atomizing chamber 102, thereby improving the atomization rate of aerosol matrix. Multiple return cotton 500s are arranged on opposite sides of atomizing core 400, without obstructing gas flow channel (the specific structure of gas flow channel will be described in detail below).

[0053] In some embodiments, the return cotton 500 is disposed in the atomizing chamber 102 and in contact with the atomizing core 400, and the upper end of the return cotton 500 is approximately flush with the liquid absorption surface 411 of the atomizing core 400.

[0054] The upper end of the return cotton 500 is roughly flush with the liquid absorption surface 411 of the atomizing core 400. The return cotton 500 can also accelerate the penetration of the aerosol matrix of the liquid absorption surface 411 into the atomizing surface 412.

[0055] In some embodiments, the base 200 includes an integrally connected base plate 210 and extension tube 230. An air inlet 211 is disposed on the base plate 210, and the extension tube 230 is disposed on the side of the base plate 210 near the atomizing core 400. The inner hole of the extension tube 230 communicates with the air inlet 211. The distance between the bottom surface of the return cotton 500 (the end face near the base plate 210) and the base plate 210 is less than the distance between the top surface of the extension tube 230 (the end face near the base plate 210) and the base plate 210. A gap is formed between the extension tube 230 and the atomizing core 400 to prevent the atomizing core 400 from blocking the gas flow channel.

[0056] Some aerosol matrix may leak into the atomization chamber 102. When the atomizer is not in use, there is a risk that the aerosol matrix in the atomization chamber 102 may leak to the outside of the atomizer through the air inlet 211. This application reduces the risk of aerosol matrix leakage and improves the utilization rate of the aerosol matrix by increasing the height of the air inlet 211 through the extension tube 230.

[0057] See Figure 3 As shown, the atomizer also includes an air intake bushing 600, one end of which is connected to the extension tube 230, and the other end of which is provided with a plurality of first connecting holes 601. For example, four first connecting holes 601 are provided at the end of the air intake bushing 600 away from the extension tube 230, and the four first connecting holes 601 are evenly spaced around the center line of the extension tube 230. A gap is formed between the air intake bushing 600 and the atomizing coil 400 to prevent the atomizing coil 400 from blocking the gas flow channel.

[0058] In some technical solutions, the base 200 is made of plastic to reduce the manufacturing cost of the atomizer. However, plastic has poor high-temperature resistance. When the distance between the extension tube 230 and the atomizing coil 400 is relatively small, the extension tube 230 is easily melted by the high temperature generated when the atomizing coil 400 heats the aerosol matrix, leading to blockage of the air intake 211. When the distance between the extension tube 230 and the atomizing coil 400 is relatively large, the risk of the aerosol matrix in the atomization chamber 102 leaking to the outside of the atomizer through the air intake 211 increases. Installing an air intake bushing 600 on the extension tube 230, which can be made of a material with better high-temperature resistance than plastic, ensures that even when the distance between the air intake bushing 600 and the atomizing coil 400 is relatively small, it will not be melted by the high temperature generated when the atomizing coil 400 heats the aerosol matrix, thus preventing blockage of the air intake 211.

[0059] In some embodiments, the intake bushing 600 is a silicone structural component, that is, the intake bushing 600 is made of silicone. The intake bushing 600 is a silicone structural component, and silicone is a flexible material. One end of the intake bushing 600 can be fitted onto the extension tube 230.

[0060] The intake bushing 600 is a silicone structural component, which can prevent the intake bushing 600 from being melted by the high temperature generated when the atomizing core 400 heats the aerosol matrix, thus preventing the intake hole 211 from being blocked. It can also facilitate the installation of the intake bushing 600 and reduce the assembly difficulty of the intake bushing 600.

[0061] It should be noted that an extension tube 230 can be installed on the base plate 210 to raise the air inlet 211, but this is not the only option. A one-way valve can also be installed at the air inlet 211, depending on the specific situation. Installing a one-way valve at the air inlet 211 allows air to enter in one direction only, which can prevent the aerosol matrix from leaking through the air inlet 211. In addition, the one-way valve can be located away from the atomizing core 400 and is not affected by the high temperature generated when the atomizing core 400 heats the aerosol matrix.

[0062] In some embodiments, the atomizer further includes a first sealing ring 710, which is disposed on the side of the bracket 300 where the drain hole 302 is opened and surrounds the drain hole 302. The top surface (liquid absorption surface 411) of the atomizing core 400 is connected to the first sealing ring 710, and the orthographic projection of the first sealing ring 710 on the top surface of the atomizing core 400 is located outside the atomizing core 400.

[0063] The first sealing ring 710 has its projection on the top surface of the atomizing core 400 outside the atomizing core 400, which can prevent the atomizing core 400 from directly contacting the support 300. Poor sealing between the atomizing core 400 and the support 300 will cause the liquid storage chamber 101 to leak from the aerosol matrix through the gap between the atomizing core 400 and the support 300, which will in turn cause excessive aerosol matrix to leak into the atomizing chamber 102.

[0064] In some embodiments, the liquid storage cup 100 includes an upper housing 110 and a lower housing 120 that are sealed together, and the upper housing 110 and the lower housing 120 can be connected by ultrasonic welding or laser welding. The accommodating cavity is a portion of the inner cavity of the lower housing 120, and the liquid storage cavity 101 is a portion of the inner cavity of the upper housing 110 and the lower housing 120. An exhaust pipe 111 is provided inside the upper housing 110, and the exhaust pipe 111 is located in the middle of the inner cavity of the upper housing 110. One end of the exhaust pipe 111 is connected to the outside of the upper housing 110, and the other end of the exhaust pipe 111 is connected to the atomizing chamber 102. The upper housing 110, the lower housing 120, the exhaust pipe 111, and the support 300 together form an annular liquid storage cavity 101. The end of the upper shell 110 away from the atomizing chamber 102 can be the mouthpiece of the atomizer. When the user inhales through the mouthpiece, the aerosol generated by the heating of the aerosol matrix by the atomizing core 400 is drawn into the user's mouth through the atomizing chamber 102 and the exhaust pipe 111.

[0065] When the upper housing 110 and the lower housing 120 are connected by a sealing ring, there is a risk of poor sealing and leakage of the aerosol matrix in the liquid storage chamber 101 from the joint between the upper housing 110 and the lower housing 120. In this application, the upper housing 110 and the lower housing 120 are connected by ultrasonic welding or laser welding, and there are no gaps between the upper housing 110 and the lower housing 120, which can avoid leakage of the aerosol matrix in the liquid storage chamber 101 from the joint between the upper housing 110 and the lower housing 120.

[0066] Furthermore, when the upper shell 110 and the lower shell 120 are integrally molded, the manufacturing process is difficult due to the irregular shapes of both. In this application, the upper shell 110 and the lower shell 120 are manufactured separately and then connected by ultrasonic welding or laser welding, which reduces the manufacturing difficulty of the liquid storage cup 100.

[0067] In some embodiments, a vent 303 is provided at the end of the bracket 300 away from the base 200, the vent 303 is centrally located, and the exhaust pipe 111 of the upper housing 110 extends into the vent 303, with a sealed connection between the exhaust pipe 111 and the vent 303. Side flow channels 304 are provided on opposite sides of the bracket 300, such as... Figure 6 As shown, the side flow channel 304 and the liquid inlet 301 are located on different sides of the vent 303. Two liquid inlets 301 can be provided, positioned on opposite sides of the vent 303, and both inlets 301 are connected to the drain hole 302. For example, the two liquid inlets 301 can be positioned on opposite left and right sides of the vent 303, and the two side flow channels 304 can be positioned on opposite front and rear sides of the vent 303. The air inlet 211, atomizing chamber 102, side flow channel 304, vent 303, and exhaust pipe 111 are sequentially connected to form a gas flow channel.

[0068] The vent 303 is centrally located, facilitating a sealed connection between the vent 303 and the exhaust pipe 111. Two liquid inlets 301 are located on opposite sides of the vent 303, and both inlets 301 are connected to the drain hole 302. The aerosol matrix disperses from the two inlets 301 into the drain hole 302, and then permeates through the substrate 410 to the atomizing surface 412. This ensures that the cross-section of the flow channel between the drain hole 302 and the storage chamber 101 is sufficiently large, allowing the aerosol matrix supply rate to meet the user's suction needs. The side flow channel 304 and the liquid inlets 301 are located on different sides of the vent 303, meaning the gas and liquid flow channels pass through different sides of the support 300. This improves space utilization and prevents the gas and liquid flow channels from intersecting and affecting gas and liquid flow.

[0069] See Figure 6As shown, a ventilation groove 305 is provided on the side wall of the support 300. The ventilation groove 305 connects the liquid storage chamber 101 and the atomizing chamber 102. The ventilation groove 305 can be provided on the contact surface between the support 300 and the first sealing ring 710. Multiple ventilation grooves 305 can be provided and arranged around the drain hole 302. The first sealing ring 710 can be a rectangular cross-section sealing ring. While connecting the support 300 and the atomizing core 400, the first sealing ring 710 can also seal the opening of the ventilation groove 305 near the side of the first sealing ring 710.

[0070] It should be noted that a ventilation groove 305 may be provided on the side wall of the bracket 300, but it is not limited to this. A ventilation hole may also be provided on the side wall of the bracket 300. The ventilation hole does not pass through the end face of the bracket 300 that contacts the liquid storage chamber 101 or the end face of the bracket 300 that contacts the first sealing ring 710. The specific details may vary depending on the circumstances.

[0071] As the aerosol matrix in the storage chamber 101 is continuously consumed, the air pressure in the storage chamber 101 will continuously decrease and form a negative pressure, which will affect the flow of the aerosol matrix through the inlet hole 301 and the outlet hole 302 to the atomizing core 400, resulting in untimely supply of aerosol matrix and affecting the user experience.

[0072] In this embodiment, a ventilation groove 305 is provided on the side wall of the support 300. The ventilation groove 305 connects the liquid storage chamber 101 and the atomizing chamber 102. When the aerosol matrix in the liquid storage chamber 101 is continuously consumed, the air pressure in the liquid storage chamber 101 will continuously decrease. The gas in the atomizing chamber 102 can enter the liquid storage chamber 101 through the ventilation groove 305, thereby balancing the air pressure in the liquid storage chamber 101 and the atomizing chamber 102, and avoiding the formation of negative pressure in the liquid storage chamber 101, which would cause the aerosol matrix supply to be untimely.

[0073] It should be understood that the flow area of ​​the ventilation groove 305 is relatively small, and the aerosol matrix in the liquid storage chamber 101 will not leak into the atomization chamber 102 through the ventilation groove 305, or only a small amount of aerosol matrix will leak into the atomization chamber 102. Since the return cotton 500 is located inside the atomization chamber 102 and in contact with the atomizing core 400, the return cotton 500 can draw the aerosol matrix in the atomization chamber 102 back to the surface of the atomizing core 400 through capillary action for secondary atomization. Even if a small amount of aerosol matrix leaks into the atomization chamber 102, it can be drawn back to the surface of the atomizing core 400 through the return cotton 500 for secondary atomization and consumption, preventing leakage of the aerosol matrix from the air inlet 211. Furthermore, to prevent the aerosol matrix from leaking into the atomization chamber 102 through the ventilation groove 305, a one-way valve can be installed at the ventilation groove 305 to allow one-way flow from the atomizing core 400 to the atomization chamber 102.

[0074] In some embodiments, the bracket 300 further includes a plurality of enclosure portions 306, which are disposed around the contact surface between the bracket 300 and the first sealing ring 710, and a side flow channel 304 is located between two adjacent enclosure portions 306. The bracket 300 also includes a connecting groove 307, which is located inside the enclosure portion 306 and connects the ventilation groove 305 and the atomizing chamber 102.

[0075] Air enters the atomizing chamber 102 through the air inlet 211 and mixes with the aerosol matrix on the atomizing surface 412 of the atomizing core 400 to form an aerosol. The aerosol then flows into the exhaust pipe 111 through the side flow channel 304. The connecting groove 307 connects the ventilation groove 305 and the atomizing chamber 102. The inlet of the connecting groove 307 is close to the atomizing surface 412. That is, the ventilation groove 305 draws air from the lower end face of the support 300. Compared with the scheme where the ventilation groove 305 draws air from the side of the support 300, the intake of aerosol into the liquid storage chamber 101 can be reduced.

[0076] In addition, the enclosure 306 surrounds the contact surface between the bracket 300 and the first sealing ring 710. The enclosure 306 can serve as a limiting structure for the first sealing ring 710, preventing the first sealing ring 710 from being improperly installed, which would cause the drain hole 302 to connect with the side flow channel 304.

[0077] In some embodiments, the base 200 further includes a side plate portion 220, which surrounds the edge of the base plate 210. The side plate portion 220 is located in the inner cavity of the lower housing 120, and the base plate 210 is located at the end of the lower housing 120 away from the upper housing 110. The edge of the base plate 210 is located outside the inner cavity of the lower housing 120, serving as the upper limit structure of the base 200. The inner sidewall of the lower housing 120 is provided with a first slot 121, and the side plate portion 220 is provided with a first buckle 221 corresponding to the first slot 121 of the lower housing 120. The lower housing 120 and the base 200 are connected by the first slot 121 and the first buckle 221. The first slot 121 and the first buckle 221 serve as the lower limit structure of the base 200.

[0078] A second slot 222 is provided at the end of the side plate 220 away from the base plate 210, and a first buckle 221 is located between the second slot 222 and the base plate 210. A second buckle 308 is provided at the end of the bracket 300 away from the liquid storage chamber 101, and the second buckle 308 is located between the return cotton 500 and the side plate 220. The base 200 and the bracket 300 are connected by the second slot 222 and the second buckle 308.

[0079] The liquid storage cup 100 is connected to the base 200 through the first slot 121 and the first buckle 221, and the base 200 and the bracket 300 are connected through the second slot 222 and the second buckle 308. The liquid storage cup 100, the base 200 and the bracket 300 are connected to prevent the base 200 and the bracket 300 from being far away from or close to the liquid storage chamber 101.

[0080] In some embodiments, the outer surface of the side plate portion 220 opposite to the lower housing 120 is provided with an annular groove structure. The atomizer also includes a second sealing ring 720, which is disposed within the annular groove structure to seal the gap between the side plate portion 220 and the lower housing 120, i.e., the gap between the base 200 and the liquid storage cup 100. The second sealing ring 720 may be an O-ring.

[0081] The second sealing ring 720 seals the gap between the base 200 and the liquid storage cup 100, preventing the aerosol matrix in the atomization chamber 102 from leaking from the gap between the base 200 and the liquid storage cup 100.

[0082] In some embodiments, the atomizer further includes a third sealing ring 730, which is disposed at the end of the support 300 near the liquid storage chamber 101. The third sealing ring 730 includes an outer cylinder portion 731, an inner cylinder portion 732, and an annular portion 733. The outer cylinder portion 731 is sleeved on the inner cylinder portion 732, and the outer cylinder portion 731 and the inner cylinder portion 732 are substantially coaxial. The annular portion 733 connects the outer cylinder portion 731 and the inner cylinder portion 732. The outer cylinder portion 731 is disposed between the support 300 and the lower housing 120, and the inner cylinder portion 732 is disposed between the exhaust pipe 111 and the vent 303. The annular portion 733 covers the end face of the support 300 near the liquid storage chamber 101. The annular portion 733 has a second connecting hole 734 at the position corresponding to the liquid inlet 301, and the second connecting hole 734 connects the liquid inlet 301 and the liquid storage chamber 101.

[0083] A third sealing ring 730 is provided at one end of the support 300 near the liquid storage chamber 101 to seal the gap between the support 300 and the lower housing 120 and the gap between the support 300 and the exhaust pipe 111. This prevents the aerosol matrix in the liquid storage chamber 101 from leaking into the atomizing chamber 102 through the gap between the support 300 and the lower housing 120 and the gap between the support 300 and the exhaust pipe 111.

[0084] This application also provides an electronic atomizing device, which includes the atomizer and power supply assembly disclosed above, with the power supply assembly connected to the atomizer. The atomizer also includes two electrodes 800, with portions of the electrodes 800 located in a groove on the side of the base plate 210 away from the atomizing core 400, and portions of the electrodes 800 passing through the base plate 210 and connected to the heating element 420 of the atomizing core 400.

[0085] An airflow sensor is also installed in the electronic atomizing device. When the user inhales into the atomizer's mouthpiece (the end of the upper housing 110 away from the lower housing 120), the resulting negative pressure triggers the airflow sensor. The airflow sensor controls the power supply component to supply power to the atomizing core 400, causing the atomizing core 400 to atomize the aerosol matrix and generate an aerosol for the user to inhale.

[0086] In this embodiment, the electronic atomizing device includes an atomizer, which includes a liquid storage cup 100, a base 200, a support 300, an atomizing core 400, and a return cotton 500. The liquid storage cup 100 includes a liquid storage chamber 101 for storing the aerosol matrix. The base 200 is disposed at one end of the liquid storage cup 100, and the support 300 is disposed inside the liquid storage cup 100 and sealed to the inner wall of the liquid storage cup 100. The two opposite ends of the support 300 are respectively provided with a liquid inlet 301 and a liquid outlet 301. 02. The inlet port 301 connects the storage chamber 101 and the outlet port 302. The atomizing core 400 is positioned between the support 300 and the base 200 and covers the outlet port 302. The atomizing core 400, the storage cup 100, and the base 200 together form the atomizing chamber 102. The return cotton 500 is positioned inside the atomizing chamber 102 and in contact with the atomizing core 400. The return cotton 500 can draw the aerosol matrix in the atomizing chamber 102 back to the surface of the atomizing core 400 through capillary action for secondary atomization. This secondary atomization via the return cotton 500 improves the atomization rate of the aerosol matrix and increases the number of suction ports for the user.
