Therefore, it should not be construed as a limitation to the present application. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0035] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0036] Please refer to Figures 1 to 4 , the present application provides an electronic atomization device 100. The electronic atomization device 100 includes an oil cup 11, a mouthpiece 70, a heating assembly 20, and a base 50. The mouthpiece 70 is disposed at one end of the oil cup 11, and the base 50 is disposed at the other end of the oil cup 11. An independent liquid storage cavity 10 and an air flow channel 30 are formed in the oil cup 11. The heating assembly 20 is disposed at the bottom of the liquid storage cavity 10. The heating assembly 20 includes a porous body 21 and a heating element 22. The porous body 21 has a heating surface 211 for setting the heating element 22. The air flow channel 30 includes an air inlet 53, an atomization chamber 31, a gas delivery section 32, and an air outlet 71 that are sequentially connected. The gas delivery section 32 is disposed outside the liquid storage cavity 10. Along the direction from the air inlet 53 to the air outlet 71, the cross-section of the porous body 21 gradually increases, so that the heating surface 211 is inclined from the air inlet 53 to the gas delivery section 32 direction in the atomization chamber 31, and the air inlet 53 is misaligned with the lowest point of the heating surface 211.

[0037] By arranging the heating surface 211 in an inclined manner, the air flow channel 30 formed by the heating surface 211 also has a certain inclination angle. After the air flow enters the electronic atomization device 100, it can flow under the guidance of the inclined air flow channel 30. When the atomization medium is heated and atomized, the aerosol formed on the heating surface 211 can, on the one hand, make the angle of the corner passed by the aerosol smoother when flowing from the air inlet to the air outlet direction, that is, when the aerosol flows from the air inlet to the air outlet, it can enter the air supply section 32 more smoothly, making the aerosol flow more smoothly, thereby reducing the loss of the aerosol and reducing the generation of condensate; on the other hand, by setting the cross-section of the porous body 21 to be a structure that gradually increases, the aerosol can be dispersed along the air supply direction and leave from the air supply section 32 respectively, avoiding a large accumulation of the aerosol in the atomization chamber 31. In this way, the amount of condensate at each position in the atomization chamber 31 can be reduced, effectively preventing the air flow channel 30 from being blocked by the condensate. Since the porous body 21 is used to absorb the atomization medium and atomize the atomization medium, when there is too much atomization medium in the porous body 21 or the atomization is not timely, the atomization medium will drip along the tip position of the porous body 21, or when the aerosol generation amount is large and not discharged from the air supply section 32 in time, condensate is easily formed. Therefore, by arranging the air inlet 53 to be misaligned with the tip position of the heating surface 211, the problem of liquid leakage caused by the atomization medium or condensate directly dripping onto the air inlet 53 can be avoided.

[0038] Exemplarily, the inclined arrangement of the heating surface 211 can form structures such as a V shape, a conical shape, a frustum shape, or a pyramid shape, and has the effect that the cross-section of the porous body 21 gradually increases along the air supply direction. Hereinafter, the case where the heating surface 211 is inclined to form a V shape will be taken as an example for description.

[0039] In some embodiments, two air supply sections 32 are respectively provided on both sides outside the liquid storage chamber 10, the heating surface 211 is provided with two, the two heating surfaces 211 are inclined, and the two heating surfaces 211 are respectively inclined from the air inlet 53 to the corresponding air supply section 32. In this way, the heating component 20 can form a V-shaped structure, and the V-shaped structure divides the atomization chamber 31 into two flow channels, and the two flow channels extend along the heating surface 211. By dividing the atomization chamber 31 into two flow channels, the aerosol can be divided into two parts and leave from the two air supply sections 32 respectively, thereby reducing the amount of condensate in a single flow channel and effectively preventing the air flow channel 30 from being blocked by the condensate. At the same time, by providing two heating surfaces 211, the area of the heating surface 211 can be increased, the atomization efficiency and the amount of aerosol output can be improved, thereby enhancing the taste experience of the user during suction; the heating surface 211 forms a V-shaped structure, which can make the structure of the heating component 20 more compact, facilitating the realization of the miniaturized design of the electronic atomization device 100.

[0040] Optionally, the heating element 22 can be in the form of a heating wire, a heating sheet, etc. The heating element 22 heats and atomizes the atomizing medium in the porous body 21 by means of electrical heating. In order to be able to energize the heating element 22, in some embodiments, a planar connecting portion 2111 is provided on the heating surface 211, and the planar connecting portion 2111 is provided with a connecting plane, and the heating element 22 extends to the connecting plane. The electronic atomization device 100 also includes an electrode column 40, which is arranged on a base 50, and the base 50 is arranged on the side of the porous body 21 away from the liquid storage chamber 10, and is spaced apart from the porous body 21 to form the atomization chamber 31, and the electrode column 40 abuts against the connecting plane to be electrically connected to the heating element 22. By setting the connecting plane, even if the heating surface 211 is set as an inclined plane, the electrode column 40 can still achieve a good connection with the heating element 22 on the heating surface 211. When the electrode column 40 abuts against the connection plane, the contact surface of the two is in the form of a plane, which can increase the contact area between the electrode column 40 and the heating element 22, ensure the stability of the electrical connection between the two, and thus improve the reliability of the heating component 20 during operation.

[0041] It is understandable that after the airflow is split into two airflows in the atomizing chamber 31, the airflows can be respectively delivered to the vicinity of the suction nozzle 70 along the two air delivery sections 32, and the two airflows are combined and ejected from the suction nozzle 70. For example, at the suction nozzle, the shape of the interior of the suction nozzle 70 can be used to guide and combine the gas, or the inverted V-shaped structure at the top of the oil filling plug can be used to guide and combine the two airflows.

[0042] Optionally, the planar connection portion 2111 may be in the form of a boss or a groove provided on the heating surface 211, and the connection plane is formed by utilizing the table surface of the boss or the bottom plane of the groove. These two examples will be introduced respectively below.

[0043] In one example, Figure 4As shown, the planar connection portion 2111 is arranged as a groove, the groove is arranged on the heating surface 211, the bottom of the groove is formed as a connection plane, the heating element 22 includes a heating area 221 and an electrode connection area 222, the electrode connection area 222 is connected to both ends of the heating area 221, the heating area 221 is arranged on the heating surface 211, and the electrode connection area 222 is bent and attached to the groove wall and the bottom of the groove. By using the groove, a plane, i.e., the connection plane, can be formed on the inclined heating surface 211. The connection plane can be used to abut against the electrode post 40. On the one hand, it can improve the stability of the electrical connection between the heating element 22 and the electrode post 40; on the other hand, the electrode post 40 can also provide a fixing function for the porous body 21. That is, the electrode post 40 provides a supporting force for the heating assembly 20 from below, so as to realize the stable connection of the electrode post 40, the porous body 21 and the liquid storage cavity 10, and improve the assembly stability of each component in the electronic atomization device 100. Exemplarily, the groove can be arranged as a triangular groove, or a groove with a polygonal inner wall. Taking the triangular groove as an example, the triangular groove can be formed at one time by using a mold with a corresponding shape when the porous body 21 is molded, or alternatively, a porous body 21 with a V-shaped structure can be first formed, and then a triangular groove is opened on the inclined surface of the porous body 21.

[0044] In another example, as Figure 6 shown, the planar connection portion 2111 is arranged as a step, the step protrudes from the heating surface 211, the step surface of the step is formed as a connection plane, the heating element 22 includes a heating area 221 and an electrode connection area 222, the electrode connection area 222 is connected to both ends of the heating area 221, the heating area 221 is arranged on the heating surface 211, and the electrode connection area 222 is bent and attached to the step surface of the step. By using the step surface of the step, a connection plane can also be formed, so as to facilitate the electrode post 40 to abut against the connection plane. Similarly, the step can be arranged as a triangular convex structure, or other convex structures with a polygonal contour.

[0045] Exemplarily, the electrode posts 40 are usually arranged in two and are respectively connected to the heating elements to form an electrical conduction loop. Therefore, in order to make the number of electrode connection areas 222 on the connection plane correspond to the number of electrode posts 40, the planar connection portion 2111 can be arranged as at least two. For example, it is arranged at the diagonal or four corners of the porous body 21. The following will introduce these two examples respectively.

[0046] In one of the examples, please refer to Figure 5 and Figure 7, planar connection portions 2111 are respectively provided at two diagonal corners of the porous body 21 facing the base 50. Two electrode posts 40 are provided on the base 50, and the two electrode posts 40 respectively abut against the connection planes of the corresponding planar connection portions 2111. By arranging the planar connection portions 2111 in a diagonal manner on the heating surface 211, on the one hand, when the electrode posts 40 abut against the connection plane, the electrode posts 40 can provide a supporting force in the diagonal direction for the heating assembly 20, making the force on the heating assembly 20 more uniform and making the connection between the electrode posts 40 and the heating assembly 20 more stable. On the other hand, after the atomization medium is atomized into an aerosol, the aerosol will impact on the objects in the flow path and generate condensate. Therefore, the electrode posts 40 are connected to the diagonal positions of the porous body 21, which can avoid the aerosol flow path and reduce the blocking effect of the electrode post 40 structure on the aerosol flow process, thereby reducing the generation of condensate. Optionally, the two planar connection portions 2111 arranged diagonally are centrosymmetrically arranged about the center of the porous body 21.

[0047] In another example, please refer to Figure 4 , Figure 6 and Figure 10 , planar connection portions 2111 are respectively provided at the four corner positions of the porous body 21 facing the base 50. Two electrode posts 40 and two support posts 51 are provided on the base 50. The two electrode posts 40 respectively abut against the connection planes of two of the diagonal planar connection portions 2111, and the two support posts 51 abut against the connection planes of the other two diagonal planar connection portions 2111. By arranging the planar connection portions 2111 at the four corner positions, the force on the porous body 21 can be made more uniform, so that the heating assembly 20 can be assembled and fixed by the electrode posts 40 and the support posts 51 of the base 50.

[0048] In order to further reduce the blocking effect of the electrode posts 40 on the aerosol airflow, in some embodiments, please refer to Figure 8 , the planar connection portion 2111 is arranged at the connection of the two heating surfaces 211. The connection planes respectively connect the two heating surfaces 211. The heating body 22 includes a heating area 221 and an electrode connection area 222 that are connected to each other. The heating area 221 is arranged on the heating surface 211, and the electrode connection area 222 extends to the connection plane and fits against the connection plane. By arranging the planar connection portion 2111 at the connection between the two heating surfaces 211, in this way, during the process of aerosol formation and flowing from the atomization chamber 31 into the air supply section 32, the electrode posts 40 will avoid the aerosol and prevent the aerosol from hitting the electrode posts 40, thereby solving the problem of aerosol condensation to generate condensate. This can not only avoid the condensate from blocking the air inlet 53, but also reduce the particle loss in the aerosol, thereby ensuring the smoke volume and taste when the user smokes.

[0049] In some embodiments, please refer to Figure 9, the porous body 21 has an oil guiding groove 212 which communicates with the liquid storage cavity 10. The porous body 21 further has a support rib plate 2121 disposed in the oil guiding groove 212. By using the oil guiding groove 212, it can be used to store the atomization medium, facilitating the better penetration of the atomization medium into the pores inside the porous body 21, achieving the effect that the porous body 21 absorbs and stores a certain amount of atomization medium. By using the support rib plate 2121, the overall strength of the oil guiding groove 212 can be improved, avoiding problems such as wall surface deformation of the oil guiding groove 212 during the oil storage process, thereby ensuring the flatness of each surface of the oil guiding groove 212 and the overall reliability.

[0050] In some embodiments, both the support rib plate 2121 and the planar connection portion 2111 are located at the central axis position of the heating component 20, and the support rib plate 2121 is connected to the planar connection portion 2111 to enhance the structural strength of the planar connection portion 2111 and avoid the problem of fracture when the planar connection portion 2111 abuts against the electrode post 40. Additionally, while ensuring the overall structural strength of the porous body 21, the wall thickness of the porous body 21 where the heating surface 211 is located can be made smaller to improve the oil guiding performance of the porous body 21 at the heating surface 211 and avoid problems such as dry burning and burnt smell caused by insufficient liquid supply in the porous body 21.

[0051] Optionally, in other examples, for example, when adopting the scheme of the electrode post 40 abutting against the diagonal positions of the porous body 21, the two heating surfaces 211 can be directly connected or can adopt an arc surface connection (as shown in Figure 3 ), and of course, a planar connection (as shown in Figure 7 ) can also be adopted. The included angle formed by the two heating surfaces 211 can also be set to different angles, for example, 80°, 90°, 100°, 120°, etc. The smaller the included angle, the faster the aerosol can move on the heating surface 211, which is beneficial to improving the transportation efficiency of the aerosol. As the included angle increases, the depth of the oil guiding groove 212 can be reduced accordingly, thereby reducing the probability of forming bubbles in the oil guiding groove 212. Or, even if bubbles are formed, due to the shallowness of the oil guiding groove 212, the bubbles can quickly rise to the liquid level of the atomization medium in the oil guiding groove 212 and disappear, thereby avoiding the blockage of the oil guiding groove 212 by bubbles and the generation of burnt smell due to dry burning of the heating component 20.

[0052] Optionally, the heating elements 22 disposed on the two heating surfaces 211 may be integrally formed, or two heating elements 22 may be welded into a V-shaped structure by means of welding or the like. When the two heating surfaces 211 are connected by an arc surface, a heating element 22 may also be disposed on the surface of the connecting arc surface, so as to connect the two heating elements 22 located on the heating surfaces 211 together. Further, a hollow portion 223 may be provided on the heating element 22 on the arc surface, so as to prevent the atomization medium from dripping. Of course, in other examples, the heating assembly 20 may also be energized by means of conductive leads, that is, instead of using the electrode post 40 to abut against the connecting plane, one end of the conductive lead may be welded to the surface of the heating element 22, and the other end of the conductive lead is connected to a power source, so as to supply power to the heating element 22. Exemplarily, a T-shaped or L-shaped gripping foot 224 may be provided on the outer periphery of the heating element 22, and the gripping foot 224 is bent and inserted into the porous body 21, so as to realize the connection between the heating element 22 and the porous body 21.

[0053] In some embodiments, please refer to Figure 2 、 Figure 3 and Figure 10 , the top surface of the base 50 is provided as an inclined surface, and the inclination direction is the same as that of the heating surface 211. The top surface of the base 50 and the heating surface 211 form an atomization chamber 31. By using the inclined surface of the top surface of the base 50, it cooperates with the inclined heating surface 211 of the porous body 21 to realize the diversion of the aerosol in the atomization chamber 31. Exemplarily, when the porous body 21 is provided as a V-shaped structure, the top surface of the base 50 is also provided as a V-shaped structure, so as to cooperate with the V-shaped structure of the porous body 21 to divide the atomization chamber 31 into two flow channels, and the two flow channels are distributed in a V shape. In this way, the shape of the top surface of the base 50 can be used to guide the air flow into the atomization chamber 31, and after the aerosol is generated by atomization, guide the aerosol to flow along the V-shaped path, so as to divide the aerosol into two gas streams, reduce the amount of condensate formed in a single flow channel, and thus prevent the condensate from blocking the intake air flow channel 30. Optionally, the inclination direction of the top surface of the base 50 is the same as that of the heating surface 211, which means that the top surface of the base 50 and the heating surface 211 may be arranged parallel to each other, or the top surface of the base 50 and the heating surface 211 have substantially the same direction, but the two planes are not parallel.

[0054] Furthermore, the base 50 is further provided with a boss 55 protruding towards the porous body 21. The top surface is formed on the boss 55. A condensate groove 52 penetrating through to the top surface of the base 50 is provided on the boss 55 for receiving condensate. The open end of the condensate groove 52 is arranged close to the connection part of the atomization cavity 31 and the air supply section 32. Along the air inlet direction, the open end of the condensate groove 52 is higher than the open end of the air inlet 53 facing the atomization cavity 31. The condensate groove 52 can be used to collect or store condensate, avoiding the accumulation of condensate at the air flow channel 30, solving the problem of liquid leakage during the use of the electronic atomization device 100, and improving the reliability and practicability of the use of the electronic atomization device 100.

[0055] In some embodiments, two air inlets 53 are provided. The two air inlets 53 are arranged at intervals on both sides of the projection of the lowest point of the porous body 21 on the base 50. In order to enable the air to sweep over a larger area of the heating surface 211 when entering the atomization cavity 31, the air inlets 53 are arranged on both sides of the tip projection. In this way, it can not only avoid the air inlets 53 facing the tip directly, thus avoiding the blockage of the air inlets 53 caused by oil leakage at the tip, but also ensure that the air can start sweeping over the heating surface 211 from the lowest point of the V-shaped structure, so as to better drive the aerosol to flow and leave the atomization cavity 31. Optionally, the two air inlets 53 are arranged as semi-circular through holes. In this way, it can not only avoid the circular air inlets facing the tip of the V-shaped structure directly, but also ensure that the ventilation area of the two air inlets 53 is the same as that of a complete circular through hole, ensuring the air intake effect of the air inlets 53.

[0056] Optionally, the end face of the air inlet 53 facing the atomization cavity 31 is arranged as an inclined surface, and the inclination direction is the same as that of the heating surface 211. By using the air inlet 53 with an inclined opening, the air flow can be guided to enter the atomization cavity 31 along the inclination direction of the heating surface 211, thus guiding the flow direction of the air flow and facilitating the air flow to flow along the V-shaped atomization cavity 31.

[0057] In some embodiments, please refer to Figure 11, a liquid collecting groove 54 is further provided on the base 50, and the opening end of the liquid collecting groove 54 facing the atomization chamber 31 is lower than the opening end of the air inlet 53 facing the atomization chamber 31. Further, a protrusion 56 is provided on the base 50, the air inlet 53 is arranged on the protrusion 56, the end face of the air inlet 53 facing the atomization chamber 31 is arranged as an inclined surface, and the inclination direction of the inclined surface is the same as the inclination direction of the heating surface 211. A liquid collecting groove 54 is formed between the outer wall of the protrusion 56 and the inner wall of the base 50. By using the liquid collecting groove 54, the condensate or the leakage of the atomization medium can be collected and stored, so as to avoid the leakage of the condensate or the leakage to the outside of the base 50, and solve the problem of liquid leakage of the electronic atomization device 100. By setting the opening end of the liquid collecting groove 54 lower than the opening end of the air inlet 53, in this way, the condensate or the leakage in the liquid collecting groove 54 will be difficult to enter the air inlet 53, avoiding the blockage of the air inlet 53, and thus ensuring the air intake reliability of the air inlet 53. By forming the liquid collecting groove 54 between the outer wall of the protrusion 56 and the inner wall of the base 50, the structure of the whole base 50 can be made more compact.

[0058] Further, the electronic atomization device 100 further includes an adsorbent 60, and the adsorbent 60 is arranged at the opening end of the liquid collecting groove 54 for adsorbing the condensate. The adsorbent 60 can be made of materials such as absorbent cotton with an internal porous structure or a fibrous structure, which can absorb the condensate in time, improve the storage capacity of the liquid collecting groove 54 for the condensate, and further improve the reliability of the electronic atomization device 100 in use.
