[0002] This application claims priority to Chinese patent applications filed on December 17, 2024, with application number 202423123155.2 entitled "Atomizer and Electronic Atomizing Device" and filed on March 20, 2025, with application number 202510332251.8 entitled "Atomizer and Electronic Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of electronic atomization technology, and in particular to an atomizer and electronic atomization device. Background Technology
[0004] Electronic atomizing devices, as an alternative to traditional cigarettes, offer advantages such as no tar, no ash, and no open flame, effectively avoiding the various harmful substances produced when traditional cigarettes are lit. Electronic atomizing devices typically consist of a power supply and an atomizer. The power supply is configured to provide power to the atomizer, which is configured to generate an inhalable aerosol.
[0005] In related technologies, an atomizer includes a mouthpiece, an oil cup, a base, and an air duct and atomizing assembly disposed within the oil cup. The mouthpiece is connected to one end of the oil cup, communicates with the air duct, and cooperates with the air duct to form an air outlet channel. The base is connected to the other end of the oil cup and has at least a partial air inlet channel. The atomizing assembly is disposed within the oil cup and includes an atomizing bracket, airflow components, a wicking element, a heating element, and a sealing element. The atomizing assembly, oil cup, base, and air duct cooperate to form an atomizing channel connecting the air outlet channel and the air inlet channel. The air inlet channel, atomizing channel, and air outlet channel constitute the airflow channel of the atomizer. However, the above-described structure requires a large number of components. On the one hand, a large number of components leads to greater assembly difficulty, resulting in lower production efficiency; on the other hand, a large number of components leads to higher production costs.

[0056] Referring to Figures 1 to 12, an atomizer according to an embodiment of this application includes an oil cup 100, a base 200, a liquid guiding component 300, and a heating element 400.
[0057] Specifically, the oil cup 100 has a hollow cavity structure. One end of the oil cup 100 along the first direction has an opening 110. The base 200 is at least partially disposed in the opening 110 and is sealed to the oil cup 100. The liquid guide 300 is disposed in the oil cup 100. The heating element 400 is disposed in the oil cup 100 and is located between the liquid guide 300 and the base 200. The heating element 400 and the base 200 at least enclose an atomizing channel a. The atomizing channel a extends along the second direction and intersects with the first direction. One of the two side walls of the oil cup 100 disposed opposite each other along the second direction is provided with an air outlet 130 communicating with the atomizing channel a.
[0058] It should be noted that the first direction mentioned above refers to the X direction in the attached figures. Specifically, in some embodiments, the first direction mentioned above refers to the lateral direction of the atomizer.
[0059] It should be noted that the second direction mentioned above is the Y direction in the attached figure. Specifically, the second direction mentioned above can be perpendicular to the first direction. In some embodiments, the second direction mentioned above is the longitudinal direction of the atomizer (i.e., the direction parallel to the direction of gravity).
[0060] During assembly, the liquid guide 300, heating element 400 and base 200 are sequentially assembled into the oil cup 100 through the opening 110 along the first direction to complete the assembly. The heating element 400 and the base 200 at least enclose and form the atomization channel a in the airflow channel of the atomizer. Compared with the prior art, the atomizer of the present application embodiment simplifies the relevant structure to reduce the required parts, which is conducive to reducing the assembly difficulty and improving production efficiency, while also helping to reduce production costs.
[0061] Furthermore, in related technologies, the atomization channel a of an atomizer is typically defined by the inner wall of a vent pipe made of metal. This vent pipe passes through the liquid storage chamber inside the oil cup 100. The heated gas in the atomization channel a undergoes heat conduction through the vent pipe wall, which can cause the atomized liquid inside the liquid storage chamber to be heated without atomizing, making it prone to deterioration. However, in the atomizer of this embodiment, the atomization channel a does not need to pass through the liquid storage chamber inside the oil cup 100, thus reducing the simmering effect of the heated gas in the atomization channel a on the atomized liquid inside the oil cup 100 due to heat conduction.
[0062] In some embodiments, the oil cup 100 is a rigid component, and the base 200 is a flexible sealing component. The portion of the base 200 located within the opening 110 is interference-fitted with the oil cup 100, ensuring a sealing contact between the portion of the base 200 within the opening 110 and the oil cup 100, thus eliminating the need for a separate sealing component. Specifically, a rigid component refers to a self-supporting structural component. As an example, the oil cup 100 can be made of a rigid non-metallic material such as plastic, or a rigid metallic material such as stainless steel. The base 200 can be made of silicone or rubber; this application does not impose specific limitations on these embodiments.
[0063] In some of these embodiments, the heating element 400 may be a planar sheet structure made of a metallic material.
[0064] In some of these embodiments, the liquid guiding element 300 is made of a flexible porous material, such as integral cotton, oil-wicking cotton, etc.
[0065] In some embodiments, the liquid guide 300 completely fills the extra cavity inside the oil cup 100, that is, there is no need to retain a separate cavity for storing atomizing liquid inside the oil cup 100, which helps to reduce the risk of leakage.
[0066] In some embodiments, one end of the liquid guide 300 abuts against the side of the heating element 400 facing away from the base 200, and the other end of the liquid guide 300 abuts against the inner wall of the oil cup 100 facing the opening 110 (i.e., the inner wall of the end of the oil cup 100 away from the opening 110). The heating element 400 and the inner wall of the oil cup 100 facing the opening 110 compress the liquid guide 300 along a first direction, so that the liquid guide 300 is in a compressed state. That is, the length dimension of the liquid guide 300 along the first direction after assembly is smaller than the length dimension of the liquid guide 300 in the first direction before assembly. This allows the liquid guide 300 and the heating element 400 to fit tightly together, which helps to reduce the situation of poor contact between the liquid guide 300 and the heating element 400. This allows the liquid guide 300 to supply atomizing liquid to the heating element 400 in a timely manner, thereby helping to keep the heating element 400 wetted by the atomizing liquid and thus helping to reduce the risk of the heating element 400 burning dry.
[0067] Specifically, the compression amount of the liquid guiding component 300 along the first direction is 1mm to 4mm. The compression amount can be 1mm, 4mm, 3mm, or other values within the aforementioned range, and is not limited here. It should be noted that the compression amount is the difference between the length of the liquid guiding component 300 along the first direction before assembly and its length along the first direction after assembly. Furthermore, if the compression amount of the liquid guiding component 300 along the first direction is too small, it may lead to poor contact between the liquid guiding component 300 and the heating element 400. If the compression amount of the liquid guiding component 300 along the first direction is too large, it may lead to a decrease in the liquid storage capacity and liquid guiding rate of the liquid guiding component 300.
[0068] Referring to Figures 1, 3, 5, 6, and 8, in some embodiments, the oil cup 100 has a protruding supporting portion 120 on its inner wall facing the opening 110. The supporting portion 120 abuts against the end of the liquid guide 300 away from the heating element 400. The heating element 400 has a heating portion 410 directly opposite the supporting portion 120 along a first direction. Since the heating element 400 mainly heats the atomizing liquid supplied by the atomizing liquid guide 300 through the heating portion 410, the supporting portion 120 ensures a tight fit between the liquid guide 300 and the heating portion 410. This helps reduce the possibility of poor contact between the liquid guide 300 and the heating portion 410, allowing the liquid guide 300 to supply atomizing liquid to the heating portion 410 in a timely manner. This helps keep the heating portion 410 wetted by the atomizing liquid, thereby reducing the risk of the heating portion 410 burning dry. Furthermore, by providing the supporting portion 120, the compression degree of the portion of the liquid guide 300 located between the supporting portion 120 and the heating portion 410 is greater than that of other portions. This results in a higher density in the portion of the liquid guide 300 located between the supporting portion 120 and the heating portion 410 compared to other portions. Consequently, the atomized liquid will flow from the portion with lower density to the portion with higher density. That is, the atomized liquid in other portions of the liquid guide 300 will automatically flow to the portion of the liquid guide 300 located between the supporting portion 120 and the heating portion 410. This helps to reduce the amount of unusable atomized liquid remaining in the liquid guide 300, thereby improving the utilization rate of the atomized liquid in the liquid guide 300.
[0069] Specifically, the orthographic projection of the heating element 410 along the first direction falls at least partially within the area of the orthographic projection of the supporting element 120 along the first direction.
[0070] It should be noted that in some embodiments, the orthographic projection of the heating element 410 along the first direction falls completely within the area of the orthographic projection of the supporting element 120 along the first direction, so as to better achieve the technical effect of the supporting element 120 described above.
[0071] Referring to Figures 1 to 4, in some embodiments, the liquid guide 300 and the inner wall of the oil cup 100 form a return air channel b that communicates with the atomization channel a, so that the space in which the oil cup 100 is configured to accommodate the liquid guide 300 can be connected to the outside atmosphere. This balances the internal and external air pressures of the space in which the oil cup 100 is configured to accommodate the liquid guide 300, thereby helping to prevent the accumulation of negative pressure in the space in which the oil cup 100 is configured to accommodate the liquid guide 300 as the atomizing liquid is consumed, and enabling the liquid guide 300 to smoothly supply atomizing liquid to the heating element 400.
[0072] Referring to Figures 1 to 8, in some embodiments, the liquid guide 300 has grooves 310 on both sides opposite to each other along the second direction. The grooves 310 extend along the first direction and cooperate with the inner wall of the oil cup 100 to form at least a portion of the return air channel b. The inner wall of the oil cup 100 facing the opening 110 has a protruding abutment 120, which abuts against the end of the liquid guide 300 away from the heating element 400, so that a gap is formed between the inner wall of the oil cup 100 facing the opening 110 and the end of the liquid guide 300 away from the heating element 400, which is connected to the grooves 310. On one side of the liquid guide 300 opposite to each other along the second direction, the groove 310 is connected to the upstream end of the atomizing channel a, and the groove 310 on the other side is connected to the downstream end of the atomizing channel a. The airflow generated by the user's inhalation in the atomizing channel a flows from the upstream end to the downstream end. Its structure is simple and facilitates the return air through the return air channel b. In addition, since a gap is formed between the inner wall of the oil cup 100 facing the opening 110 and the end of the liquid guide 300 away from the heating element 400, which is connected to the groove 310, it is not easy to trap air bubbles when injecting atomizing liquid into the liquid guide 300 installed in the oil cup 100.
[0073] It should be noted that in some other embodiments, the groove 310 described above may also be provided on the inner wall of the oil cup 100, which is not limited here.
[0074] Referring to Figures 1 to 4, in some of the embodiments, the groove 310 near the air outlet 130 has two open ends, and the heating element 400 blocks a portion of the open end facing the base 200, so that the atomized liquid in the space containing the liquid guide 300 is not easily leaked from the air outlet 130 through the return air channel b.
[0075] It should be noted that in some of the embodiments, a portion of the orthographic projection of the groove 310 near the air outlet 130 along the second direction falls into the air outlet 130, which helps to improve the smoothness of air return during the return air channel b.
[0076] Specifically, along the first direction, the heating element 400 is located on the side of the center line of the air outlet 130 close to the liquid guiding element 300, so that the effective area of the air outlet 130 configured as the outlet of the atomization channel a is larger than the effective area of the air outlet 130 configured as the return air channel b. This helps to ensure that the aerosol in the atomization channel a can flow smoothly out of the air outlet 130, thereby reducing the risk of aerosol remaining in the atomization channel a and forming condensate.
[0077] Specifically, along the first direction, the distance between the inner wall of the air outlet 130 near the liquid guide 300 and the heating element 400 is 0.4mm to 0.6mm. This distance can be 0.4mm, 0.6mm, 0.5mm, or other values within the above range, and is not limited here.
[0078] Referring to Figures 1 to 11, in some embodiments, the base 200 is provided with an atomizing groove 210 on the side facing the heating element 400, and the heating element 400 and the atomizing groove 210 enclose each other to form an atomizing channel a, which has a simple structure and is easy to implement.
[0079] Specifically, the base 200 is provided with an air inlet 220 that is connected to the end of the atomizing tank 210 away from the air outlet 130.
[0080] It should be noted that in some other embodiments, the air inlet 220 described above can also be provided on the side wall of the oil cup 100. Specifically, the end of the atomizing channel a that is away from the air outlet 130 along the second direction passes through the side wall of the oil cup 100 to form the air inlet 220 described above. Of course, the air inlet 220 can also be provided on other side walls of the oil cup 100, which is not limited here.
[0081] Referring to Figures 6, 8, 9 and 11, in some embodiments, the liquid guiding component 300 includes a first porous body 320 and a second porous body 330. The first porous body 320 is disposed between the second porous body 330 and the heating element 400. Both the first porous body 320 and the second porous body 330 are made of flexible porous material. The end of the second porous body 330 away from the first porous body 320 abuts against the inner wall of the oil cup 100 facing the opening 110. That is, the liquid guiding component 300 has a split structure.
[0082] It should be noted that in some embodiments, the heat resistance temperature of the first porous body 320 is higher than that of the second porous body 330, that is, the heat resistance of the first porous body 320 is better than that of the second porous body 330, which helps to reduce the risk of the first porous body 320 being burned due to the excessive temperature of the heating element 400.
[0083] It should be noted that in some embodiments, the porosity of the first porous body 320 is lower than that of the second porous body 330. For the same volume, the liquid storage capacity of the second porous body 330 is greater than that of the first porous body 320. This makes the second porous body 330 mainly configured to store liquid, while the first porous body 320 is mainly configured to guide the atomized liquid in the second porous body 330 to the heating element 400. Since the liquid storage capacity of the first porous body 320 is relatively weak, the first porous body 320 has a certain liquid-locking effect compared to the second porous body 330, which helps to reduce the leakage of atomized liquid through the first porous body 320.
[0084] It should be noted that in some embodiments, the liquid storage volume of the first porous body 320 is smaller than that of the second porous body 330, resulting in a greater liquid storage capacity of the second porous body 330 than that of the first porous body 320. In this case, the second porous body 330 is mainly configured to store liquid, while the first porous body 320 is mainly configured to guide the atomized liquid in the second porous body 330 to the heating element 400. Since the liquid storage capacity of the first porous body 320 is relatively weak, the first porous body 320 has a certain liquid-locking effect compared to the second porous body 330, which helps to reduce the leakage of atomized liquid through the first porous body 320.
[0085] It should be noted that in some of the embodiments, the first porous body 320 is oil-wicking cotton, and the second porous body 330 is integral cotton.
[0086] It should be noted that in some embodiments, the heating element 400 and the oil cup 100 compress the first porous body 320 and the second porous body 330 along the first direction towards the inner wall of the opening 110, so that the first porous body 320 and the second porous body 330 are in a compressed state, that is, the length dimension of the first porous body 320 and the second porous body 330 along the first direction after assembly is smaller than the length dimension of the assembly front edge along the first direction, so that the first porous body 320 and the second porous body 330 can fit tightly together, and the first porous body 320 and the heating element 400 can fit tightly together. This helps to reduce the possibility of poor contact between the first porous body 320 and the second porous body 330 and between the first porous body 320 and the heating element 400, so that the first porous body 320 can supply atomizing liquid to the heating element 400 in a timely manner, thereby helping to keep the heating element 400 in a state of being wetted by atomizing liquid, and thus helping to reduce the risk of the heating element 400 burning dry.
[0087] It should be noted that in some embodiments, the second porous body 330 has a first region in contact with the first porous body 320 and a second region not in contact with the first porous body 320. The density of the first region is greater than that of the second region. The atomized liquid will flow from the part with lower density to the part with higher density. That is, the atomized liquid in the second region of the second porous body 330 will automatically flow to the first region of the second porous body 330 and be guided by the first porous body 320 to the heating element 400. This helps to reduce the amount of unusable atomized liquid remaining in the second porous body 330, thereby improving the utilization rate of the atomized liquid in the second porous body 330.
[0088] It should be noted that in some embodiments, the second porous body 330 has several fibers extending in the same direction. The extension direction of the fibers of the second porous body 330 is parallel to the first direction, so that the second porous body 330 has a higher support strength along the first direction. This makes it easier for the density of the first region and the second region to change after the second porous body 330 is compressed, and thus the density of the first region is still greater than the density of the second region.
[0089] It should be noted that in some embodiments, the first porous body 320 has several fibers extending in the same direction. The extension direction of the fibers of the first porous body 320 is parallel to the second direction, so that the support strength of the first porous body 320 along the first direction is low, thereby enabling the first porous body 320 to better fit the heating element 400 after being compressed, which is beneficial to ensuring the liquid guiding effect of the first porous body 320.
[0090] Referring to Figure 11, in some embodiments, the cross-sectional area of the first porous body 320 is smaller than that of the second porous body 330, so that the end face of the second porous body 330 near the first porous body 320 only partially contacts the first porous body 320. This results in a greater degree of compression in the area where the second porous body 330 contacts the first porous body 320 than in other areas of the second porous body 330. Consequently, the density of the area where the second porous body 330 contacts the first porous body 320 is greater than in other areas of the second porous body 330. The atomized liquid will flow from the low-density area to the high-density area. That is, the atomized liquid in other areas of the second porous body 330 will automatically flow to the area where the second porous body 330 contacts the first porous body 320 and be guided by the first porous body 320 to the heating element 400. This helps to reduce the amount of unusable atomized liquid remaining in the second porous body 330, thereby improving the utilization rate of the atomized liquid in the second porous body 330.
[0091] It should be noted that in some other embodiments, the liquid guiding component 300 may also be an integral structure, which is not limited here.
[0092] Referring to Figures 5 to 11, in some embodiments, the heating element 400 includes a heating portion 410 and an electrode portion 420 connected to the heating portion 410. The atomizer also includes a conductive portion 430 electrically connected to the electrode portion 420, and the conductive portion 430 is configured to be connected to an external power source.
[0093] Specifically, the conductive part 430 is disposed on the base 200. Of course, the conductive part 430 can also be disposed on the side wall of the oil cup 100, which is not limited here.
[0094] Referring to Figures 5 and 6, in some embodiments, the heating element 410, the electrode element 420, and the conductive element 430 are integrally formed.
[0095] It should be noted that in some other embodiments, the heating element 410, electrode element 420, conductive element 430, and base 200 may be integrally formed, and this is not limited here. In this case, the number of components required for the atomizer can be further reduced, thereby improving assembly efficiency during production.
[0096] Referring to Figures 7, 8, and 11, in some other embodiments, only the heating element 410 and the electrode element 420 may be integrally formed, which is not limited here. In this case, the conductive element 430 is independent of the heating element 400.
[0097] Referring to Figures 9 to 11, in some embodiments, the heating element 410 is located at the end of the atomizing channel a away from the air outlet 130. When the atomizer is in use, the extending direction of the atomizing channel a (i.e., the second direction mentioned above) is usually parallel to the direction of gravity. At this time, the air outlet 130 is located at the top of the atomizer. Due to the influence of gravity, the atomized liquid flowing to the heating element 400 will gather towards the lower part of the atomizing channel a, that is, the atomized liquid will gather towards the end of the atomizing channel a away from the air outlet 130. By placing the heating element 410 at the end of the atomizing channel a away from the air outlet 130, the gathered atomized liquid can be heated and atomized in a timely manner, thereby improving the utilization rate of the atomized liquid.
[0098] When the liquid guiding member 300 includes a first porous body 320 and a second porous body 330, the first porous body 320 has a portion that contacts the heating part 410. Since the extension direction of the fiber filaments of the first porous body 320 is parallel to the second direction, the atomized liquid will preferentially flow along the extension direction of the fiber filaments of the first porous body 320 based on capillary action, so that the atomized liquid in the first porous body 320 can preferentially flow to the heating part 410.
[0099] When the cross-sectional area of the first porous body 320 is smaller than that of the second porous body 330, since the first porous body 320 needs to have a part that contacts the heating part 410, the first porous body 320 is cross-shaped or "+" shaped, which makes the first porous body 320 less demanding on the assembly direction, has a foolproof function, and thus helps to improve the yield.
[0100] Of course, the first porous body 320 can also be T-shaped, L-shaped or other shapes, which are not limited here.
[0101] Referring to Figures 11 and 12, in some embodiments, the base 200 is provided with a mounting through hole 230 configured to allow the conductive part 430 to pass through. The mounting through hole 230 is a stepped hole, so that the mounting through hole 230 has a first section 231 with a larger diameter and a second section 232 with a smaller diameter, that is, the diameter of the first section 231 is larger than the diameter of the second section 232. The first section 231 is located on the side of the mounting through hole 230 near the heating element 400. The end of the conductive part 430 near the heating element 400 is provided with a limiting part 431 that accommodates the first section 231. A limiting surface is formed at the junction of the first section 231 and the second section 232, which cooperates with the limiting part 431 to limit the movement. During assembly, the liquid guide 300 will squeeze the heating element 400, causing the heating element 400 to squeeze the conductive part 430. Through the cooperation between the limiting part 431 and the limiting surface, the conductive part 430 can be prevented from leaving the preset assembly position when squeezed by the heating element 400. In addition, the limiting part 431 can increase the contact area between the electrode part 420 and the conductive part 430, which helps to reduce the possibility of poor contact between the electrode part 420 and the conductive part 430.

The power supply device 10 is connected to the atomizer 20 and configured to supply power to the atomizer 20.
