[0033] The present application discloses an electronic atomization device 100, referring to Figure 1 to Figure 3 , Figure 1 is a structural schematic diagram of an embodiment of the electronic atomization device provided by the present application, Figure 2 is Figure 1 is an exploded structural schematic diagram of the electronic atomization device shown in Figure 3 is Figure 1 is a cross-sectional structural schematic diagram of the electronic atomization device shown in.

[0034] The electronic atomization device 100 is used to atomize aerosol generating substrate to generate aerosol when powered on, which can be used in different fields, such as drug atomization, agricultural spraying, hair spray atomization, and oil liquid atomization, etc. Among them, the aerosol generating substrate can be tobacco tar, liquid medicine or nutrient solution, etc.

[0035] The electronic atomization device 100 comprises an atomization cartridge 10, a heating top cover 20, an atomization core 30, a base 40, a battery 50, a control element (not shown), and a shell 64. The atomization cartridge 10 is internally provided with a liquid storage cavity 12 for storing an aerosol generating substrate. The heating top cover 20 is arranged in the atomization cartridge 10. The atomization core 30 is connected to the heating top cover 20. The base 40 is located on a side of the heating top cover 20 away from the liquid storage cavity 12 and is connected to the atomization cartridge 10. The battery 50 is arranged on the base 40 and is electrically connected to the atomization core 30. The control element is electrically connected to the battery 50 and is used to control the battery 50 to supply power to the atomization core 30. The shell 64 covers the outer periphery of the atomization cartridge 10, the base 40, and the battery 50.

[0036] In other embodiments, the battery 50 can also be arranged on a side of the base 40 away from the heating top cover 20 without being connected to the base 40.

[0037] Specifically, as shown in Figure 3 , the atomization cartridge 10 comprises a shell 11 and an air outlet pipe 13. The shell 11 is in a cylindrical structure with one end closed and the other end open. The air outlet pipe 13 is located in the shell 11 and is connected to the closed end of the shell 11 and communicates with the outside through the closed end, i.e., the closed end is provided with an air outlet hole 14, and the air outlet pipe 13 communicates with the air outlet hole 14. The user inhales the aerosol generated in the electronic atomization device 100 through the air outlet pipe 13 and the air outlet hole 14. The liquid storage cavity 12 is arranged between the shell 11 and the air outlet pipe 13.

[0038] The heating top cover 20 is embedded in the shell 11 from the open end of the shell 11. One end of the air outlet pipe 13 is inserted into the air mist outlet hole 21 of the atomization seat 20, and the atomization seat 20 and the shell 11 and the air outlet pipe 13 and the air mist outlet hole 21 are all sealed to prevent liquid leakage.

[0039] The heating top cover 20 is further provided with a liquid inlet hole 22. The aerosol generating substrate in the liquid storage cavity 12 flows to the atomization core 30 through the liquid inlet hole 22. The atomization core 30 is used to atomize the aerosol generating substrate to generate an aerosol.

[0040] Specifically, in combination with Figure 3 and Figure 4 , wherein Figure 4 is Figure 3 the assembly structure diagram of the heating top cover and the atomization core shown in

[0041] The heating top cover 20 comprises a cover body 23 and a flow guide wall 24 arranged on the cover body 23. The cover body 23 is provided with a liquid inlet hole 22 and an air mist outlet hole 21, and both the liquid inlet hole 22 and the air mist outlet hole 21 communicate with an atomization cavity 25 formed by the flow guide wall 24. The flow guide wall 24 is provided with an air inlet 26, and the air inlet 26 communicates with the atomization cavity 25.

[0042] The cover 23 is embedded in the shell 11, and the air outlet pipe 13 is inserted into the air mist outlet hole 21. The electronic atomization device 100 further comprises a top cover sealing piece 61, which covers one end of the cover 23 facing the liquid storage cavity 12, so that the atomization seat 20 and the shell 11 and the air outlet pipe 13 and the air mist outlet hole 21 are sealed.

[0043] The atomization core 30 is connected with the heating top cover 20, and the atomization core 30 is arranged corresponding to the liquid inlet hole 22. The atomization core 30 has a liquid suction surface 31 and an atomization surface 32. The liquid suction surface 31 covers the liquid inlet hole 22, that is, the liquid suction surface 31 completely blocks the liquid inlet hole 22, so that the liquid in the liquid storage cavity 12 can flow to the liquid suction surface 31 of the atomization core 30 through the liquid inlet hole 22. The atomization surface 32 is located in the atomization cavity 25. The atomization core 30 guides the aerosol generating substrate from the side where the liquid suction surface 31 is located to the side where the atomization surface 32 is located, and the aerosol generating substrate is atomized at the atomization surface 32 to generate aerosol.

[0044] The first port 261 of the air inlet 26 is communicated to the atomization cavity 25, and the second port 211 of the air mist outlet hole 21 is communicated to the atomization cavity 25. The first port 261 and the second port 211 are respectively located on two opposite sides of the atomization core 30, so that the airflow enters the atomization cavity 25 from the air inlet 26 and flows through the atomization surface 32 and the air mist outlet hole 21 in sequence.

[0045] In an embodiment, the atomization core 30 is a rectangular body, which further has a first side 33 and a second side 34. The first side 33 and the second side 34 are oppositely arranged, and the first side 33 and the second side 34 are adjacent to the liquid suction surface 31 and the atomization surface 32. The second port 211 is located on the side where the first side 33 is located, and the first port 261 is located on the side where the second side 34 is located. Therefore, during the process that the airflow flows from the air inlet 26 to the air mist outlet hole 21, the airflow can cross the atomization surface 32, so that the generated aerosol after atomization can be carried away to a greater extent and with higher efficiency, that is, the airflow can more fully carry the generated aerosol on the atomization surface 32 to the air outlet pipe 13, so as to avoid the aerosol from being retained in the atomization cavity 25, effectively improve the aerosol output, and be beneficial to improving the atomization efficiency.

[0046] In this embodiment, the atomization surface 32 is a rectangular surface, which includes two opposite first edges 321 and two opposite second edges 322. The length of the first edge 321 is not less than the length of the second edge 322. The first port 261 and the second port 211 are respectively located on two sides of the two first edges 321. The airflow flowing from the air inlet 26 to the air mist outlet hole 21 flows through the atomization surface 32 in a direction that one first edge 321 points to the other first edge 321, that is, the airflow can cross the atomization surface 32 by approximately crossing the length dimension of the second edge 322, so as to more efficiently and more quickly carry away the generated aerosol.

[0047] In other embodiments, the first port 261 and the second port 211 can also be located on two sides of the two second edges 322 respectively, so that the airflow flowing to the air outlet 21 through the air inlet 26 is directed to the other second edge 322 along the interval direction of the two second edges 322, so as to be able to carry away the aerosol generated after atomization to a greater extent and with higher efficiency.

[0048] In other embodiments, the atomization surface 32 can also be a circular surface or an elliptical surface, and the airflow is substantially directed along a straight line direction across the atomization surface 32; the atomization core 30 can also be a trapezoidal body or a cylindrical body, and the present application does not make specific limitations thereto.

[0049] In the present embodiment, the second port 211 is located in the atomization cavity 25, and the air outlet 21 is spaced apart from the outer peripheral wall of the cover 23, in other words, the air outlet 21 directly communicates with the atomization cavity 25, and the airflow from the atomization cavity 25 to the air outlet 21 does not need to pass through the inner peripheral wall of the shell 11, that is, the risk of condensation of the aerosol generated by atomization in contact with the inner peripheral wall of the shell 11 is eliminated, the risk of aerosol condensation remaining in the atomization cavity 25 is effectively reduced, and the aerosol production of the electronic atomization device 100 can be further improved.

[0050] Specifically, the air outlet 21 is a through hole, and it directly communicates with the atomization cavity 25, and the aerosol generated in the atomization cavity 25 can directly pass to the air outlet pipe 13 without passing through the inner peripheral wall of the shell 11.

[0051] Optionally, the hole path of the air outlet 21 can also be curved, and the second port 211 can also be located outside the atomization cavity 25, and the airflow from the atomization cavity 25 to the second port 211 can also flow through the inner peripheral wall of the shell 11.

[0052] In the present embodiment, the air outlet 21 is centrally arranged on the cover 23, and the air outlet 21 is spaced apart from the outer peripheral wall of the cover 23, and the air outlet pipe 13 is a straight pipe, and one end of the air outlet pipe 13 is connected to the air outlet 21, so that the airflow can directly pass from the atomization cavity 25 to the air outlet pipe 13 through the air outlet 21, that is, the airflow can flow to the air outlet pipe 13 along the shortest path without being wound from both sides of the top cover to the air outlet 21 as in the prior art, and the path of the airflow carrying the aerosol is relatively shortened, and the time of the aerosol from the atomization cavity 25 to the air outlet 14 is reduced, so that the temperature drop of the aerosol can be effectively alleviated, and the aerosol production can be improved and the condensate can be reduced, so that the aerosol entering the user's oral cavity can maintain a relatively high temperature, so as to bring a better taste to the user.

[0053] The aerosol outlet 21 is centrally located on the cover 23, and the air inlet 26 is relatively eccentrically located. The air inlet 26 and the aerosol outlet 21 are located on both sides of the two first sides 321, which can relatively reduce the size of the electronic atomizing device 100 along the second side 322, thereby facilitating the miniaturization of the electronic atomizing device 100 and making it easier for users to carry.

[0054] Continue reading Figure 2 and Figure 3 The base 40 is located on the side of the heating top cover 20 away from the liquid storage chamber 12. The base 40 can be physically connected to the atomizing chamber 10, for example, the base 40 can be snapped or threaded to the housing 11 of the atomizing chamber 10. At the same time, the side of the base 40 facing the heating top cover 20 abuts against one end of the guide wall 24, or the base 40 can be embedded in the housing 11 from the open end of the atomizing chamber 10, and at the same time, the base 40 can be physically connected to the guide wall 24 or abut against one end of the guide wall 24.

[0055] In this embodiment, the base 40 is connected to the guide wall 24 and is located on the side of the guide wall 24 away from the cover 23. The base 40 is provided with at least one air hole 41, which is located on the outside of the guide wall 24 away from the atomizing chamber 25. The airflow flows through the air hole 41 along the guide wall 24 to the air inlet 26.

[0056] Specifically, the housing 10 is provided with a bayonet, and the outer periphery of the base 40 is provided with a locking tooth for engaging with the bayonet on the housing 10; furthermore, the base 40 is also engaged with the guide wall 24, or the base 40 can also be inserted into the guide wall 24, for example, one of them is provided with a positioning post, and the other is provided with a positioning hole for assembly with the positioning post, and the positioning post and the positioning hole are inserted into each other.

[0057] The electronic atomizing device 100 also includes a base seal 62, which covers the end of the base 40 facing the heating top cover 20, so that the base 20 and the housing 11 and the base 40 and the guide wall 24 are sealed, thereby ensuring that the airflow in the space between the heating top cover 20 and the base 40 flows through the air hole 41, the guide wall 24, the air inlet 26, the atomizing surface 32 and the atomization outlet 21 in sequence, so as to avoid the airflow from freely escaping uncontrollably.

[0058] See also Figure 5 to Figure 7 ,in Figure 5 yes Figure 4 The diagram shows a bottom view of the structure of the heating top cover. Figure 6 yes Figure 3 The diagram shows the assembly structure of the heating top cover and the base. Figure 7 yes Figure 3 A schematic diagram of the base in the electronic atomizing device shown.

[0059] Specifically, such asFigure 5 and Figure 6 As shown, the guide wall 24 divides the space between the cover 23 and the base 40 into two layers: an inner layer, which is the atomizing cavity 25 enclosed by the guide wall 24, and an outer layer, which is the preheating cavity 27 between the outer side of the guide wall 24 away from the atomizing cavity 25 and the inner wall of the housing 11. The preheating cavity 27 surrounds the atomizing cavity 25 to isolate the atomizing cavity 25 from the inner peripheral wall of the housing 11. The vent 41 connects the atmosphere and the preheating cavity 27, so the airflow must pass through the preheating cavity 27 to enter the atomizing cavity 25. The preheating cavity 27 is used to preheat the airflow and store condensate, so that the temperature of the airflow entering the atomizing cavity 25 is higher and the humidity is lower. The preheating cavity 27 also has the function of heat preservation for the atomizing cavity 25, which can effectively slow down the rate of temperature dissipation in the atomizing cavity 25 and help maintain a higher temperature in the atomizing cavity 25 to improve atomization efficiency.

[0060] Specifically, the guide wall 24 is used to direct the airflow to the air inlet 26 and preheat the airflow.

[0061] The atomizing core 30 can be connected to the cover 23 and / or the guide wall 24. When the atomizing core 30 is working, it generates heat and diffuses the heat to its surroundings. The guide wall 24 can transfer the heat generated by the atomizing core 30 to preheat the airflow entering through the air hole 41 as it flows in the preheating chamber 27.

[0062] Furthermore, the air vent 41 is located in the preheating chamber 27 on the outside of the guide wall 24 away from the atomizing chamber 25, rather than directly connected to the atomizing chamber 25. This increases the time and path length for the airflow to enter the atomizing chamber 25, thereby enabling efficient preheating of the airflow.

[0063] In this embodiment, as Figure 5 As shown, the guide wall 24 has a receiving groove 28, which is connected to the liquid inlet 22. The atomizing core 30 is disposed in the receiving groove 28, and the guide wall 24 can transfer the heat generated by the atomizing core 30, so that the atomizing core 30 can be in close contact with the guide wall 24 to transfer heat more efficiently.

[0064] Furthermore, the cover 23 can also transfer the heat generated by the atomizing core 30 and preheat the airflow.

[0065] In other embodiments, the cover 23 may be provided with a receiving groove 28 that communicates with the liquid inlet hole 22.

[0066] In this embodiment, the cover 23 is provided with a ventilation groove 230, which surrounds the liquid inlet hole 22 and connects the liquid inlet hole 22 and the atomizing chamber 25. The ventilation groove 230 has a capillary effect. The electronic atomizing device 100 includes a sealing gasket 63, which covers the ventilation groove 230 and is located between the atomizing core 30 and the cover 23. Thus, the liquid storage chamber 12 can adjust the internal air pressure through the ventilation groove 230 to avoid the dry burning situation caused by insufficient liquid supply to the atomizing core 30 due to the drop in internal air pressure.

[0067] Furthermore, multiple condensation grooves are provided on the outer side of the guide wall 24 and the side of the cover 23 facing the base 40. As the airflow flows along the guide wall 24 in the preheating chamber 27, it can provide condensation efficiency for the airflow, thereby reducing the humidity of the airflow and making the airflow entering the atomization chamber 25 drier. This can improve atomization efficiency and carry the generated aerosol more efficiently, thereby increasing the aerosol output and reducing the humidity of the aerosol.

[0068] like Figure 5 and Figure 6 As shown, the guide wall 24 includes a guide ring wall 242 and a partition wall 244. The guide ring wall 242 surrounds and forms an atomizing chamber 25, and the partition wall 244 connects to the side of the guide ring wall 242 away from the atomizing chamber 25. The base 40 is provided with a plurality of air holes 41, which are located on both sides of the partition wall 244.

[0069] Specifically, the baffle wall 244 can divide the preheating cavity 27 outside the flow guide ring wall 242 into two sub-spaces, and there is a gap between the baffle wall 244 and the inner wall of the shell 11 to increase the flow of the two sub-spaces. The multiple air holes 41 are divided into two parts and respectively disposed on both sides of the baffle wall 244 to provide an airflow entry position in each of the two sub-spaces, so that the airflow at the two locations flows in the corresponding sub-spaces to preheat the airflow more fully and improve the preheating efficiency.

[0070] Furthermore, the guide wall 24 also includes at least two positioning posts 246, which are connected to the outer side of the guide ring wall 242 away from the atomizing chamber 25, and are used to align and assemble with the base 40.

[0071] In this embodiment, the positioning post 246 is provided with an alignment hole, and the base 40 is provided with an alignment post 43. The alignment post is inserted into the alignment hole so that the heating top cover 20 and the base 40 are aligned and assembled, thereby simplifying the assembly difficulty between them and improving the assembly efficiency.

[0072] Optionally, the base 40 is provided with a positioning hole, and the positioning post 246 is assembled with the positioning hole, which can also simplify the assembly difficulty between the base 40 and the heating top cover 20.

[0073] In the embodiment, the at least two positioning columns 246 cooperate with the partition wall 244 to divide the preheating cavity 27 outside the flow guide ring wall 242 into at least four subspaces, and the plurality of air holes 41 are respectively located in two subspaces on both sides of the partition wall 244.

[0074] The four subspaces are in communication with each other, the at least two positioning columns 246 are located on both sides of the partition wall 244, so that the subspaces are formed between the partition wall 244 and the adjacent positioning columns 246, the subspaces are formed between the positioning columns 246 and the air inlet 26, and the subspaces can also be formed between two adjacent positioning columns 246 on one side of the partition wall 244.

[0075] For example, the number of the positioning columns 246 is two, and the two positioning columns 246 are respectively located on both sides of the partition wall 244, so that two subspaces are formed between the partition wall 244 and the adjacent positioning columns 246 on both sides, and two subspaces are formed between the positioning columns 246 on both sides and the air inlet 26, that is, the airflow on one side separated by the partition wall 244 needs to pass through two subspaces to enter the air inlet 26. The positioning columns 246 are arranged outside the flow guide ring wall 242, so that a small gap is formed between the positioning columns 246 and the inner wall of the shell 11, that is, the positioning columns 246 can slow down the flow rate of the airflow, so as to increase the time spent by the airflow flowing through the preheating cavity 27, so that the airflow can be more fully preheated, and the atomization efficiency is further improved.

[0076] The electronic atomization device 100 further comprises two electrodes 70, both of which are mounted on the base 40 and electrically connected with the atomization core 30; wherein the two electrodes 70 are respectively arranged adjacent to two side edges of the air inlet 26, and the two side edges are spaced apart along the circumferential direction of the flow guide ring wall 242. In a preferred embodiment, the two electrodes 70 are arranged spaced apart along the extension direction of the first edge 321, so as to reduce the blocking effect of the electrodes 70 on the airflow entering the atomization cavity 25 from the air inlet 26, and the airflow can relatively flow more smoothly, and most of the airflow entering the atomization cavity 25 from the air inlet 26 passes between the two electrodes 70, so as to efficiently carry away the aerosol generated between the two electrodes 70, and improve the aerosol output.

[0077] Different from the prior art, the application discloses an electronic atomization device. By arranging the air inlet and the aerosol outlet hole on two opposite sides of the atomization core respectively, the airflow can cross the atomization surface during the process of flowing from the air inlet to the aerosol outlet hole, so as to more greatly and more efficiently carry away the aerosol generated after atomization, that is, the airflow can more fully carry the aerosol generated on the atomization surface to the aerosol outlet hole, so as to avoid the aerosol remaining in the atomization cavity, effectively improve the aerosol output, and be beneficial to improving the atomization efficiency.

[0078] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
