[0044] The electronic atomization device generally includes an atomization core, an atomization chamber, an air inlet channel and an air outlet channel. The atomization core is arranged in the atomization chamber, and the atomization chamber is connected to the air inlet channel and the air outlet channel respectively, while the air inlet channel is connected to the outside air. At present, a commonly used air intake method is to intake air from the center of the bottom of the atomization chamber. The atomization core is located at the top of the atomization chamber, and the atomization surface faces the bottom of the atomization chamber. The air inlet channel is located directly below the atomization core. The external airflow enters from directly below the atomization core and blows toward the atomization core to bring out the high-temperature atomized gas generated after the atomization of the atomization core; and airflow channels are arranged on both sides of the atomization core. The atomized gas is diverted through the airflow channels on both sides of the atomization core and converges at the top of the atomization core, which increases the contact between the atomized gas and the wall of the airflow channel, thereby increasing the amount of condensate formed; and the airflow diversion is easy to form turbulence, which affects the airflow velocity, and also increases the amount of condensate formed; affecting the air output and taste of the electronic atomization device.

[0045] Based on this, in order to solve the above problems, the present application designs an atomizer, in which the external airflow flows from the air inlet channel at the bottom of the atomizing chamber through the air outlet channel at the top of the atomizer to bring out the atomized gas, the airflow will not be split, and the airflow turbulence is reduced; and the air inlet of the air inlet channel and the air outlet of the air outlet channel are arranged diagonally relative to the atomizing chamber, and the projection of the airflow path from the air inlet to the air outlet on the first plane crosses the projection of the atomizing surface on the first plane; that is, the projection of the airflow path from the air inlet to the air outlet on the first plane approaches the projection of the atomizing surface The center of the atomizer core is designed so that the airflow can flow through the central atomization area of ​​the atomizer core, and the atomized gas released by the atomizer core can be quickly brought out from the atomization chamber, which is conducive to increasing the airflow velocity to reduce the amount of condensate formed, so that the large-particle sweetener molecules in the atomized gas can reach the user's mouth faster, and the taste of the atomizer is improved; and the airflow path between the air inlet channel and the air outlet channel can be appropriately increased, and the path of the airflow passing through the atomization area of ​​the atomizer core can be extended, so as to bring out all the atomized gas formed by the atomizer core as much as possible, thereby improving the air output and atomization efficiency of the atomized gas.

[0046] An embodiment of the present application provides an electronic atomization device, including an atomizer 1000 and a power supply assembly (not shown), wherein the power supply assembly is used to supply power to the atomizer 1000.

[0047] It can be understood that the atomizer 1000 is used to store the aerosol-generating substrate and atomize the aerosol-generating substrate to form an aerosol that can be inhaled by the user. The power supply assembly includes a battery for powering the atomizer 1000, and the battery is electrically connected to the atomizer 1000 through the electrode ejector 11, and the electrode ejector 11 is penetrated in the atomizer 1000.

[0048] Please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 In some embodiments, the atomizer 1000 includes a shell assembly 1 and an atomizer core 2. The shell assembly 1 is formed with an atomizer cavity 3, an air inlet channel 4 for introducing airflow, and an air outlet channel 5 for leading out airflow; the air inlet channel 4 and the air outlet channel 5 are respectively extended along a first direction X and are connected to the atomizer cavity 3, and the first direction X is parallel to the central axis of the atomizer 1000; the atomizer core 2 is arranged in the shell assembly 1; the atomizer core 2 is located at the top of the atomizer cavity 3, and the atomizer core 2 has An atomizing surface 201 facing the bottom of the atomizing chamber 3; an air inlet channel 4 having an air inlet 401 located at the bottom of the atomizing chamber 3, and an air outlet channel 5 having an air outlet 501 located at the top of the atomizing chamber 3; the air inlet 401 and the air outlet 501 are arranged diagonally relative to the atomizing chamber 3, and a projection of an air flow path from the air inlet 401 to the air outlet 501 on a first plane e crosses a projection of the atomizing surface 201 on the first plane e, and the first plane e is perpendicular to the first direction X.

[0049] Specifically, the aerosol generating substrate is stored in the atomizer 1000, and the atomizer core 2 is used to atomize the aerosol generating substrate to generate atomized gas. The atomizing surface 201 of the atomizer core 2 is located at the top of the atomizing chamber 3 and faces the bottom of the atomizing chamber 3; that is, the atomizing core 2 releases the generated atomized gas downward into the atomizing chamber 3, and the atomizing area of ​​the atomizer core 2 is located in the atomizing chamber 3. When the user inhales the atomizer 1000, the external airflow enters the bottom of the atomizing chamber 3 from the air inlet channel 4, and carries the atomized gas generated by the atomization of the atomizer core 2 to the air outlet channel 5 at the top of the atomizing chamber 3 to reach the user's mouth. The external airflow can smoothly bring the atomized gas out of the atomizing chamber 3, and the airflow will not be diverted, that is, the airflow velocity is stable, which is conducive to reducing the amount of condensate formed.

[0050] The first direction X is the X direction shown in the figure, and the first direction X is parallel to the central axis of the atomizer 1000 ; the first direction X extends along the outlet channel 5 and the inlet channel 4 respectively along the first direction X. The first plane e is any plane perpendicular to the first direction X.

[0051] Understandably, reference Figure 2 , Figure 3 The atomizing chamber 3 can be regarded as a cavity similar to a three-dimensional rectangular structure, the air inlet 401 and the air outlet 501 are arranged diagonally relative to the atomizing chamber 3, the air inlet 401 is located at one of the corners of the bottom of the atomizing chamber 3, and the air outlet 501 is located at one of the corners of the top of the atomizing chamber 3, that is, the air outlet 501 is located obliquely above the air inlet 401; and the air outlet 501 and the air inlet 401 must also satisfy that the projection of the air flow path between the two on the first plane e crosses the projection of the atomizing surface 201 on the first plane e; through such a design, the projection of the air flow path from the air inlet channel 4 to the air outlet channel 5 on the first plane e approaches the geometric center of the projection of the atomizing surface 201 on the first plane e, so that the air flow can flow through the central atomizing area of ​​the atomizing core 2, and the atomized gas can be better brought out of the atomizing chamber 3.

[0052] In the atomizer 1000 of the present application, the external air flow flows from the air inlet channel 4 through the atomizing chamber 3 and the air outlet channel 5 to bring out the atomized gas, the air flow will not be split, and the air flow turbulence is reduced; and the air inlet 401 of the air inlet channel 4 and the air outlet 501 of the air outlet channel 5 are arranged diagonally relative to the atomizing chamber 3, and the projection of the air flow path from the air inlet 401 to the air outlet 501 on the first plane e crosses the projection of the atomizing surface 201 on the first plane e, so that in the first plane e, the air flow path from the air inlet channel 4 to the air outlet channel 5 approaches the geometric center of the atomizing surface 201, so that the air flow can flow through the central atomizing area of ​​the atomizing core 2, and can quickly bring the atomized gas released by the atomizing core 2 out of the atomizing chamber 3, which is beneficial to increase the air flow rate to reduce the amount of condensate formed, so that the large-particle sweetener molecules in the atomized gas can reach the user's mouth faster and improve the taste.

[0053] Furthermore, by arranging the air inlet 401 of the air inlet channel 4 and the air outlet 501 of the air outlet channel 5 diagonally relative to the atomizing chamber 3, the airflow path between the air inlet 401 and the air outlet 501 can be appropriately increased, and the path of the airflow passing through the atomizing area of ​​the atomizing core 2 can be extended, so that all the atomized gas formed by the atomizing core 2 can be brought out as much as possible, thereby improving the air output volume and atomization efficiency of the atomized gas.

[0054] refer to Figure 2 , Figure 3 In some embodiments, a plane rectangular coordinate system is established with the intersection of the first plane e and the central axis of the atomizer 1000 as the coordinate origin, and the width direction and the length direction of the cross section of the shell assembly 1 in the first plane e as the first axis direction and the second axis direction respectively; the quadrant where the projection of the air inlet 401 in the plane rectangular coordinate system is located is opposite to the quadrant where the projection of the air outlet 501 in the plane rectangular coordinate system is located.

[0055] Specifically, refer to Figure 3That is, when the quadrant where the projection of the air outlet 501 of the air outlet channel 5 in the plane rectangular coordinate system is located in the second quadrant of the plane rectangular coordinate system, the quadrant where the projection of the air inlet 401 of the air inlet channel 4 in the plane rectangular coordinate system is located in the fourth quadrant of the rectangular coordinate system, the quadrants where the projections of the two in the plane rectangular coordinate system are located are not adjacent; and the air outlet 501 is located obliquely above the air inlet 401, and then it can be regarded that the air outlet 501 and the air inlet 401 are arranged diagonally relative to the atomization chamber 3.

[0056] It can be understood that the quadrant where the projection of the air outlet 501 in the plane rectangular coordinate system covers the largest area is defined as the quadrant where the projection of the air outlet 501 in the plane rectangular coordinate system is located; and the quadrant where the projection of the air inlet 401 in the plane rectangular coordinate system covers the largest area is defined as the quadrant where the projection of the air inlet 401 in the plane rectangular coordinate system is located.

[0057] In some embodiments, reference Figure 3 , Figure 6 The atomizing surface 201 is parallel to the first plane e, and the shape of the atomizing surface 201 is similar to a rectangle, and the atomizing surface 201 has a first corner 202 and a second corner 203 that are diagonally opposite each other; the projection position of the air outlet 501 in the plane rectangular coordinate system is close to the first corner 202 of the atomizing surface 201; the projection position of the air inlet 401 in the plane rectangular coordinate system is close to the second corner 203 of the atomizing surface 201 or coincides with the second corner 203 of the atomizing surface 201.

[0058] Specifically, the atomizing core 2 is a cuboid structure, and the atomizing surface 201 is rectangular, which is suitable for the atomizer 1000 that is generally flat in the market; that is, the length direction and the width direction of the atomizing surface 201 respectively form the first axis and the second axis direction in the plane rectangular coordinate system.

[0059] In some embodiments, reference Figure 6 , the projection position of the air outlet 501 in the plane rectangular coordinate system is close to the first corner 202 of the atomizing surface 201; the projection position of the air inlet 401 in the plane rectangular coordinate system is close to the second corner 203 of the atomizing surface 201, that is, the projection of the air inlet 401 in the plane rectangular coordinate system and the projection of the air outlet 501 in the plane rectangular coordinate system are arranged diagonally; then, in the direction of the connecting line of the two diagonals of the atomizing core 2, the external airflow is sucked in by the air inlet channel 4 on one side and exhausted by the air outlet channel 5 on the other side, and the airflow can pass through the central atomizing area of ​​the atomizing core 2 along the diagonal line of the atomizing chamber 3 as a path, so that the airflow flows smoothly and the flow rate is fast, the external airflow can better pass through the atomizing area of ​​the atomizing core 2, and can quickly carry the atomized gas to the air outlet 501.

[0060] refer to Figure 6, the projection of the air outlet channel 5 in the plane rectangular coordinate system is located outside the projection of the atomizing surface 201 in the plane rectangular coordinate system and close to the first corner 202 of the atomizing surface 201; the projection of the air inlet channel 4 in the plane rectangular coordinate system is located outside the atomizing surface 201 and close to the second corner 203 of the atomizing surface 201. That is, the external airflow enters from the bottom side of the atomizing core 2, which can avoid the airflow collision between the external airflow and the atomized gas released by the atomizing core 2, and the external airflow can quickly pass through the atomizing area of ​​the atomizing core 2, which can better bring out the atomized gas; and the airflow can completely flow through the atomizing area of ​​the atomizing core 2 in the diagonal direction, better bring out the atomized gas, and improve the atomization amount of the atomizer 1000.

[0061] refer to Figure 3 In some embodiments, the projection position of the air inlet channel 4 in the plane rectangular coordinate system coincides with the second corner 203 of the atomizing surface 201. It can be understood that, limited by the structural size of the atomizer 1000, the projection position of the air inlet channel 4 in the plane rectangular coordinate system can also coincide with the second corner 203 of the atomizing surface 201, so long as the air inlet channel 4 and the air outlet channel 5 are diagonally inlet.

[0062] In some embodiments, the shape of the atomized surface 201 may also be non-rectangular; for example, referring to Figure 7 , the shape of the atomizing surface 201 is circular; then the projection position of the air outlet channel 5 in the plane rectangular coordinate system and the projection position of the air inlet channel 4 in the plane rectangular coordinate system are set to be symmetrical relative to the center of the circle as much as possible, so that the air flow path between the air inlet channel 4 and the air outlet channel 5 can flow through the atomizing area of ​​the atomizing core 2 along the diameter direction of the atomizing surface 201, better bring out the atomized gas, improve the atomization amount of the atomizer 1000, and the structural layout is reasonable.

[0063] refer to Figure 2-Figure 5 In some embodiments, the shell assembly 1 includes a main shell 101 and a heating seat 102 disposed at the bottom of the main shell 101; the main shell 101 and the heating seat 102 are combined to form an atomization chamber 3; the main shell 101 is formed with an air outlet channel 5 and an air outlet 501, and the atomization core 2 is disposed in the main shell 101; the heating seat 102 is formed with an air inlet channel 4 and an air inlet 401.

[0064] Specifically, a liquid storage chamber 6 is formed in the main shell 101 and is located above the atomizer core 2 . The liquid storage chamber 6 is used to store a liquid aerosol generating substrate, and the aerosol generating substrate can be transported to the atomizer core 2 under the action of gravity.

[0065] The bottom end of the main shell 101 is the end directly facing the atomizing surface 201 of the atomizing core 2. The heating seat 102 is connected to the bottom end of the main shell 101 and the two enclose an atomizing chamber 3, and a sealing member is provided between the two to form a good sealing effect inside the atomizer 1000. The atomizing surface 201 of the atomizing core 2 faces downward to the atomizing chamber 3. The air outlet channel 5 is located on the side of the atomizing core 2 to be isolated from the liquid storage chamber 6.

[0066] refer to Figure 2-Figure 4 In some embodiments, the heating seat 102 includes a wall platform 7 forming the bottom surface of the atomization chamber 3 and a boss 8 protruding upward from the wall platform 7, the boss 8 forms an air inlet channel 4, and the top surface of the boss 8 is formed with an air inlet port 401 connecting the air inlet channel 4 and the atomization chamber 3.

[0067] Specifically, refer to Figure 4 The wall platform 7 forms the bottom surface of the liquid storage chamber 6, the boss 8 protrudes upward from the wall platform 7, the air inlet channel 4 is formed in the boss 8, and the air inlet 401 is opened on the top surface of the boss 8 so that the air inlet 401 is higher than the wall platform 7. After the external air flows through the air inlet channel 4, it enters the atomization chamber 3 through the air inlet 401; the purpose of designing the height of the air inlet 401 to be higher than the wall platform 7 is: since the atomization core 2 releases the atomized gas downward into the atomization chamber 3, the atomized gas contacts the wall platform 7 and condenses to form condensate. By setting the boss 8 to protrude upward from the wall platform 7, the height of the air inlet 401 is higher than the wall platform 7, which can prevent the condensate from flowing into the air inlet channel 4 from the air inlet 401 and causing liquid leakage, thereby improving product reliability.

[0068] In some embodiments, the distance between the air inlet 401 and the atomizing surface 201 in the first direction X ranges from 2 to 5 mm. For example, the height difference between the air inlet 401 and the atomizing surface 201 may be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5 mm, etc.; the height difference between the air inlet 401 and the atomizing surface 201 is preferably 3 mm, so that the air inlet 401 is closer to the atomizing core 2, and when the atomizer 1000 is inhaled, the external airflow can carry the atomized gas to the air outlet channel 5 more quickly.

[0069] refer to Figure 3-Figure 7 In some embodiments, the heating seat 102 is provided with two ejector pin mounting holes 10 for mounting an electrode ejector pin 11 electrically connected to the atomizer core 2, and the projections of the geometric centers of the two ejector pin mounting holes 10 in the plane rectangular coordinate system are respectively located in the other two opposite quadrants in the rectangular coordinate system.

[0070] It can be understood that the battery of the power supply assembly is electrically connected to the positive and negative electrodes of the atomizer core 2 through the two electrode pins 11, so as to provide electrical energy to the atomizer core 2, so that the atomizer core 2 can be powered on and heated. The electrode pin 11 is inserted into the heating seat 102 along the first direction X, and the top of the electrode pin 11 is connected to the electrode of the atomizer core 2.

[0071] refer to Figure 3 , the quadrant where the projection of the air inlet channel 4 in the plane rectangular coordinate system is located is opposite to the quadrant where the projection of the air outlet channel 5 in the plane rectangular coordinate system is located; the projections of the geometric centers of the two ejector mounting holes 10 in the plane rectangular coordinate system are respectively located in the other two opposite quadrants. That is, when the projection of the geometric center of the air outlet channel 5 in the plane rectangular coordinate system is in the second quadrant, and the projection of the geometric center of the air inlet channel 4 in the plane rectangular coordinate system is in the fourth quadrant; then the projections of the geometric centers of the two ejector mounting holes 10 in the plane rectangular coordinate system are respectively located in the first quadrant and the third quadrant.

[0072] After the two electrode ejectors 11 are installed in the two ejector mounting holes 10, the central atomization area in the atomization chamber 3 can be cleared between the two electrode ejectors 11, allowing the airflow between the air inlet channel 4 and the air outlet channel 5 to pass smoothly, thereby increasing the amount of smoke; and enabling the sweetener molecules in the atomized gas to reach the user's mouth faster, thereby increasing the sweetness and improving the taste of the atomizer 1000.

[0073] In some embodiments, the atomizing surface 201 is rectangular in shape, and the projection of the air inlet channel 4 in the plane rectangular coordinate system is diagonally arranged with the projection of the air outlet channel 5 in the plane rectangular coordinate system, that is, the projection of the geometric center of the two ejector mounting holes 10 in the plane rectangular coordinate system is arranged along another diagonal line of the atomizing surface 201; the structural layout is reasonable, which improves the space utilization rate in the atomizer 1000, makes the airway more unobstructed, and the airflow can flow through the atomizer 1000 more smoothly.

[0074] In some embodiments, reference Figure 8 The electrode ejector pin 11 includes an ejector pin body 1101 and a connecting seat 1102 disposed at the bottom end of the ejector pin body 1101 . The ejector pin body 1101 is disposed away from the geometric center of the connecting seat 1102 .

[0075] It can be understood that the ejector body 1101 is diagonally arranged relative to the atomizing surface 201 in the atomizing chamber 3, and the connection seat 1102 at the bottom end of the electrode ejector 11 needs to be electrically matched with the spring pin on the battery. Therefore, there are different requirements for the setting positions of the ejector body 1101 and the connection seat 1102. Therefore, the ejector body 1101 is set away from the geometric center of the connection seat 1102, so that the two are not concentric in the first direction X, and each can meet the position assembly requirements. The structural design is ingenious.

[0076] In some embodiments, the ejector body 1101 includes a main body 1401 and connecting parts 1402 respectively disposed at two opposite ends of the main body 1401 , and the outer diameter of the main body 1401 is smaller than the outer diameter of the connecting part 1402 .

[0077] Specifically, the outer diameter of the main body 1401 is smaller than the outer diameter of the connecting portion 1402, which can reduce the space occupied by the main body 1401 in the atomization chamber 3, reduce the interference between the airflow flowing through the air inlet channel 4 and the air outlet channel 5 and the main body 1401, and reduce the airflow resistance.

[0078] refer to Figure 1 , Figure 2 In some embodiments, a nozzle portion 12 is formed at the top of the shell component 1, and a nozzle air passage 1201 communicating with the external airflow is formed in the nozzle portion 12. The shell component 1 is formed with a corner air passage 13 connecting the nozzle air passage 1201 with the air outlet passage 5, and the extension direction of the corner air passage 13 forms an angle with the first direction X.

[0079] It can be understood that the shell assembly 1 also includes a nozzle shell 103 arranged at the top of the main shell 101, and a seal is provided between the two, so that a good sealing effect is formed inside the atomizer 1000; the nozzle portion 12 is formed at the middle position of the top of the nozzle shell 103, and the airflow flows from the air outlet channel 5 through the corner airway 13 to the nozzle airway 1201 for the user to inhale; the extension direction of the corner airway 13 is at an angle to the first direction X, so that the corner airway 13 is similar to the chamfer formed between the air outlet channel 5 and the nozzle airway 1201, which is beneficial to reduce the airflow resistance, make the airflow turn and flow faster, and make the airflow pass through the airway better.

[0080] refer to Figure 2 , Figure 3 In some embodiments, the cross-sectional area of ​​the outlet channel 5 on the first plane e ranges from 7 to 20 mm. 2 .

[0081] For example, the cross-sectional area of ​​the air outlet channel 5 on the first plane e can be 7, 10, 12, 14, 16, 18, or 20 mm. 2 .

[0082] Understandably, if the air outlet channel 5 is spacious, the air flow rate will be slow, affecting the air outlet effect of the atomized gas. Therefore, setting the air outlet channel 5 in a narrow range can increase the air flow rate, so that the atomized gas can quickly reach the user's mouth, ensure the temperature and sweetness of the atomized gas, and improve the smoking taste; and can also reduce the contact area between the atomized gas and the inner wall of the air outlet channel 5, reducing the amount of condensate formed.

[0083] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
