[0002] At present, in the common electronic atomizer, the atomization substrate is heated by the atomization core to generate aerosol, but some condensate will inevitably be produced in the use process. The condensate flows downward from the atomization cavity. In order to collect the condensate, a collection space (such as a collection bin or a collection groove) is usually arranged below the atomization cavity. However, due to space limitation, too much condensate will cause the collection space to accumulate liquid too quickly. After the collection space is full, the accumulated liquid will still overflow, which is easy to flow into the induction airway, causing the corresponding airflow sensor to be abnormal or invalid, affecting the normal use of the atomizer, and also possibly causing the condensate to leak outward, affecting the user experience.

In the application, a sealing assembly is arranged in the shell of the atomizer to divide the internal space of the shell into a liquid storage cavity and a gas guiding cavity, and an atomization core assembly is arranged in the liquid storage cavity and communicates with the gas outlet, and a guide structure with a vent hole is arranged on the sealing assembly at the connection position of the atomization core assembly, the vent hole is used to communicate the atomization cavity of the atomization core assembly with the gas guiding cavity, and the arc structure on the guide structure is used to block and guide the condensed liquid flowing down the side wall of the atomization cavity, so that the condensed liquid flows to the edge of the guide structure, avoiding the condensed liquid flowing directly into the gas guiding cavity below through the vent hole, and also preventing the condensed liquid from leaking outward. In the application, the first direction is specifically the height direction, and the following examples are the same as this.
[0039] Some embodiments of the atomizer and the atomization equipment provided in the application are described below in combination with the accompanying drawings.
[0040] In the embodiments of the first aspect of the application, an atomizer 100 is provided, as shown in Figure 1 Figure 2 Figure 3 Figure 4 The atomizer 100 includes a shell 1, a sealing assembly 2 and an atomization core assembly 3. The shell 1 has an accommodating space inside, the sealing assembly 2 is arranged inside the shell 1 and sealingly cooperates with the inner side wall of the shell 1 to divide the internal space of the shell 1 into a liquid storage cavity 141 and a gas guiding cavity 142 which are isolated from each other; in the first direction, an end of the shell 1 is provided with a gas outlet 111 and an air inlet 112, and the other end of the shell 1 is provided with a sensing air channel 121 which extends into the shell 1 along the first direction; wherein the liquid storage cavity 141 is located on the side of the sealing assembly 2 facing the gas outlet 111, the gas guiding cavity 142 is located on the side of the sealing assembly 2 facing the sensing air channel 121, and the gas guiding cavity 142 communicates with the air inlet 112 and the sensing air channel 121. The atomization core assembly 3 is arranged in the liquid storage cavity 141 and arranged along the first direction; the atomization core assembly 3 has an atomization cavity 312 inside, one end of the atomization cavity 312 is connected with the gas outlet 111, the other end is sealingly connected with the sealing assembly 2, the atomization core assembly 3 has a liquid inlet 311, and the atomization substrate stored in the liquid storage cavity 141 can enter the atomization cavity 312 through the liquid inlet 311; correspondingly, the sealing assembly 2 has a guide structure 221 at the connection position of the atomization core assembly 3, the guide structure 221 has an outwardly protruding arc structure 2211 on the side facing the atomization core assembly 3, and the arc structure 2211 is provided with a vent hole 2212 to communicate the atomization cavity 312 with the gas guiding cavity 142 through the vent hole 2212.
[0041] When the atomizer 100 is applied in an atomization device, the atomization core assembly 3 can be electrically connected with the power supply assembly to supply power to the atomization core assembly 3 through the power supply assembly to heat the atomization substrate, and the induction air channel 121 of the atomizer 100 can be in communication with an air channel in which an airflow inductor of the atomization device is located, and the air outlet 111 can be in communication with a mouthpiece structure of the atomization device. When a user performs a suction action through the mouthpiece structure, airflow movement is generated inside the atomizer 100, the airflow inductor generates an induction signal and transmits it to the power supply assembly, the power supply assembly energizes and heats the atomization core assembly 3, the atomization substrate in the atomization cavity 312 is heated and atomized to generate aerosol, and the gas in the air guide cavity 142 flows into the atomization cavity 312 through the air hole 2212 and carries the aerosol to flow to the mouthpiece structure.
[0042] It can be understood that in the existing atomization device, when condensate is generated in the atomization cavity, the condensate usually adheres to the inner side wall of the atomization cavity and flows downward under the action of gravity and accumulates in the air guide cavity below the atomization cavity. When the accumulated liquid is too large to overflow, it is easy to cause the condensate to flow into the induction air channel and cause the airflow inductor to be abnormal or fail, affecting the normal work of the atomization device, and also easily causing the device to leak liquid.
[0043] The atomizer 100 in the embodiment, by improving and optimizing the structure, the connecting part of the sealing assembly 2 and the atomization core assembly 3 is provided with a guide structure 221 having an outward convex arc-shaped structure 2211. Not only can the air flow pass through the air hole 2212 on the guide structure 221, but also the arc-shaped structure 2211 can guide the condensate formed in the atomization cavity 312, so that at least part of the condensate flows along the surface of the arc-shaped structure 2211 to the edge of the guide structure 221, thereby remaining in the atomization cavity 312, so as to reduce the amount of condensate flowing into the air guide cavity 142 through the air hole 2212, thereby delaying the speed of the area for storing condensate in the air guide cavity 142 to overflow, prolonging the service life of the device, and also preventing the condensate from overflowing due to excessive accumulation, thereby improving the use experience.
[0044] It can be understood that by delaying the speed of the condensate in the atomization cavity 312 entering the air guide cavity 142 through the air hole 2212, part of the condensate is first stored on one side of the atomization cavity 312, and when the atomization core assembly 3 heats up during subsequent use, part of the condensate can also be heated and evaporated, so that the condensate is discharged in the form of gas. If the condensate directly flows into the air guide cavity 142 through the air hole 2212, it is difficult to be evaporated again during subsequent use due to its distance from the atomization core assembly 3, which will make the accumulated liquid in the air guide cavity 142 flow faster.
[0045] It should be noted that in practical applications, the arc-shaped structure 2211 on the guide structure 221 can be configured in different ways. For example, it can form an arc in one direction, for example... Figure 5 Examples are provided. At least a portion of the guide structure 221 is a partial sidewall of a cylindrical structure. It can also form an arc shape in multiple intersecting directions, or in a partial or complete circumferential region. For example, in a top-view perspective, the arc-shaped structure 2211 covers a partial circumferential region of the guide structure 221; alternatively, the entire circumferential region of the guide structure 221 can be arc-shaped. Furthermore, depending on the installation height, the guide structure 221 can also include a partially cylindrical structure extending along the first direction or a hollow prism structure, such as... Figure 6 In the example, the height of the arc-shaped structure 2211 is increased. The specific design can be adjusted according to the usage requirements and the specific structural form inside the atomizing chamber 312. In addition, the number and shape of the vent holes 2212 can also be set according to actual needs.
[0046] In further embodiments of this application, such as Figure 3 , Figure 4 In the example shown, at least a portion of the arc-shaped structure 2211 on the guide structure 221 is a spherical structure, so that an arc can be formed in any direction of the circumference through the spherical structure, thereby expanding the guiding range of the condensate; the spherical structure extends into the atomizing cavity 312 so that the inner wall of the atomizing cavity 312 is not directly facing the spherical structure in the first direction. This prevents the condensate from flowing downwards along the inner wall of the atomizing cavity 312 and directly falling onto the spherical structure or passing directly through the vent 2212, so that the condensate on the inner wall of the atomizing cavity 312 first flows to the circumferential outer side of the guide structure 221, utilizing the space on the circumferential outer side of the guide structure 221 to store a portion of the condensate, which helps to slow down the velocity of the condensate flowing into the lower air guiding cavity 142. Specifically, the radius of the spherical structure can be set according to the structural dimensions of the atomizing cavity 312 to adapt to it.
[0047] Furthermore, such as Figure 7 In the example shown, the guide structure 221 is entirely spherical, ensuring that any position on the guide structure 221 is a point on the arc. This allows the condensate to flow towards the lateral edge under the influence of gravity and the guiding effect of the spherical surface, enhancing the guiding effect on the condensate and reducing its adhesion to the guide structure 221. This further reduces the amount of condensate entering the air guide cavity 142 through the vent hole 2212. It should be noted that in practical applications, the spherical structure can be designed as follows: Figure 7 The hemispherical structure shown in the figure, that is, in Figure 7from the perspective of the ball surface structure, the central angle of the ball surface structure is 180°, of course, it can also be set to be less than 180° or greater than 180° according to the needs, for example, 100°, 120°, 150°, 160°, 200°, 240°, it can be understood that if the central angle of the ball surface structure is too small, the flow guiding ability is weak, the condensate attached to the surface of the ball surface structure is not easy to flow to the outer edge, and it is easy to directly flow into the ventilation hole 2212, if the central angle of the ball surface structure is too large, the processing and manufacturing difficulty will be increased, at the same time, the volume will also be increased, which is not conducive to assembly in a small space, and the appropriate angle can be selected for application to balance the above two aspects.
[0048] In the example of the ball surface structure, the central angle of the ball surface structure is 180°, of course, it can also be set to be less than 180° or greater than 180° according to the needs, for example, 100°, 120°, 150°, 160°, 200°, 240°, it can be understood that if the central angle of the ball surface structure is too small, the flow guiding ability is weak, the condensate attached to the surface of the ball surface structure is not easy to flow to the outer edge, and it is easy to directly flow into the ventilation hole 2212, if the central angle of the ball surface structure is too large, the processing and manufacturing difficulty will be increased, at the same time, the volume will also be increased, which is not conducive to assembly in a small space, and the appropriate angle can be selected for application to balance the above two aspects. Figure 7 In the example of the ball surface structure, the central angle of the ball surface structure is 180°, of course, it can also be set to be less than 180° or greater than 180° according to the needs, for example, 100°, 120°, 150°, 160°, 200°, 240°, it can be understood that if the central angle of the ball surface structure is too small, the flow guiding ability is weak, the condensate attached to the surface of the ball surface structure is not easy to flow to the outer edge, and it is easy to directly flow into the ventilation hole 2212, if the central angle of the ball surface structure is too large, the processing and manufacturing difficulty will be increased, at the same time, the volume will also be increased, which is not conducive to assembly in a small space, and the appropriate angle can be selected for application to balance the above two aspects.
[0049] Further, in the example of the ball surface structure, the number of ventilation holes 2212 on the ball surface structure is multiple, so as to increase the ventilation amount, and the multiple ventilation holes 2212 are arranged at intervals in the circumferential direction of the ball surface structure, preferably, the multiple ventilation holes 2212 are uniformly arranged in the circumferential direction as shown in the example of the ball surface structure, so that the airflow in the air guiding cavity 142 can flow into the atomization cavity 312 more uniformly, which is conducive to the full mixing of the aerosol generated in the atomization cavity 312 and the airflow. Among the multiple ventilation holes 2212, part of the ventilation holes 2212 are arranged opposite to the pin structure 331 of the atomization core assembly 3, so that the pin structure 331 can pass through the ventilation hole 2212, so as to facilitate the formation of a conductive structure on the shell 1 for electrical connection with the power supply assembly; and since the pin structure 331 is usually led out of the atomization cavity 312, the pin structure 331 directly passes through the ventilation hole 2212, which forms a certain degree of integrated design, and there is no need to additionally provide a wire passing hole and a corresponding anti-condensation structure on the sealing assembly 2, which is conducive to simplifying the overall structure design. Figures 2 to 4 Figure 2 In the example of the ball surface structure, the central angle of the ball surface structure is 180°, of course, it can also be set to be less than 180° or greater than 180° according to the needs, for example, 100°, 120°, 150°, 160°, 200°, 240°, it can be understood that if the central angle of the ball surface structure is too small, the flow guiding ability is weak, the condensate attached to the surface of the ball surface structure is not easy to flow to the outer edge, and it is easy to directly flow into the ventilation hole 2212, if the central angle of the ball surface structure is too large, the processing and manufacturing difficulty will be increased, at the same time, the volume will also be increased, which is not conducive to assembly in a small space, and the appropriate angle can be selected for application to balance the above two aspects.
[0050] In the example of the ball surface structure, the central angle of the ball surface structure is 180°, of course, it can also be set to be less than 180° or greater than 180° according to the needs, for example, 100°, 120°, 150°, 160°, 200°, 240°, it can be understood that if the central angle of the ball surface structure is too small, the flow guiding ability is weak, the condensate attached to the surface of the ball surface structure is not easy to flow to the outer edge, and it is easy to directly flow into the ventilation hole 2212, if the central angle of the ball surface structure is too large, the processing and manufacturing difficulty will be increased, at the same time, the volume will also be increased, which is not conducive to assembly in a small space, and the appropriate angle can be selected for application to balance the above two aspects. Figure 7
[0051] In further embodiments of the present application, as shown in Figure 3 , Figure 4 and Figure 7 , in the atomizer 100, the sealing assembly 2 has a connecting groove 222 on the side facing the liquid storage cavity 141, the atomizing core assembly 3 extends into the connecting groove 222 at the end facing the sealing assembly 2 and abuts against the groove bottom wall of the connecting groove 222; the inner side wall of the connecting groove 222 has a first sealing protrusion 2222, and the outer side wall of the part of the atomizing core assembly 3 extending into the connecting groove 222 is sealingly matched with the first sealing protrusion 2222, so as to form a sealing connection between the atomizing core assembly 3 and the sealing assembly 2. Wherein, the groove bottom wall of the connecting groove 222 is provided with a guide structure 221, and the guide structure 221 extends into the inside of the atomizing cavity 312 of the atomizing core assembly 3. On the one hand, the atomizing core assembly 3 can be used to keep the vent hole 2212 isolated from the liquid storage cavity 141, and on the other hand, the vent hole 2212 of the guide structure 221 can be higher than the bottom surface of the atomizing core assembly 3 in the first direction, so that the condensed liquid adhering to the inner side wall of the atomizing cavity 312 will not directly flow into the vent hole 2212 of the guide structure 221 during the downward flow. Wherein, the first sealing protrusion 2222 can adopt the annular sealing structure as shown in Figure 8 , and the number thereof can also be multiple and arranged in the first direction to enhance the sealing effect. Of course, in actual application, a split sealing ring can also be sleeved outside the atomizing core assembly 3 to seal the gap between the atomizing core assembly 3 and the connecting groove 222.
[0052] Further, in a specific example, as shown in Figure 3 and Figure 8 , the sealing assembly 2 also has a gas guide hole 2231, which is located in the side area of the connecting groove 222 and corresponds to the air inlet 112 of the shell 1; the shell 1 has an air inlet duct 114 extending in the first direction, one end of the air inlet duct 114 is connected with the air inlet 112, and the other end of the air inlet duct 114 extends into the gas guide hole 2231, so that the air inlet 112 and the gas guide cavity 142 are communicated through the air inlet duct 114; the inner side wall of the gas guide hole 2231 has a second sealing protrusion 2232, and the outer side wall of the part of the air inlet duct 114 extending into the gas guide hole 2231 is sealingly matched with the second sealing protrusion 2232, so as to keep the gas guide hole 2231 isolated from the liquid storage cavity 141. Wherein, the second sealing protrusion 2232 can adopt the annular sealing structure as shown in Figure 8 , and the number thereof can also be multiple and arranged in the first direction to enhance the sealing effect. Of course, in actual application, a split sealing ring can also be sleeved outside the air inlet duct 114 to seal the gap between the air inlet duct 114 and the gas guide hole 2231.
[0053] Further, in one specific example, as shown in the examples of Figure 8 , Figure 9 and Figure 10 , the sealing assembly 2 specifically comprises a split sealing base 21 and a flexible sealing member 22. The sealing base 21 can be made of a hard material (e.g. PEEK material) and is assembled with the inner wall of the shell 1; the sealing base 21 and the end of the shell 1 away from the air outlet 111 form an air guide cavity 142.

The airway groove 421 is arranged on the support structure 412 on the side facing the upper chamber, and the atomizer 100 is arranged in the upper chamber; the airway groove 421 completely covers the sensing airway 121 at the bottom of the atomizer 100 and is in sealed connection with the atomizer base 12, and the airflow sensor 422 is in communication connection with the electric control panel 432. The suction nozzle structure 411 is a filter tip structure and is arranged at the top of the main shell 410 at a position corresponding to the air outlet 111, part of the suction nozzle structure 411 extends into the atomizer 100 and is in sealed connection with the shell 1 of the atomizer 100.
[0062] As Figure 2 , Figure 4 and Figure 15 , the shell 1 of the atomizer 100 is provided with a plurality of air inlets 112 at the top, and a rotatable air inlet switch 113 is connected above the air inlets 112, part of the air inlet switch 113 is exposed by the main shell 410 to facilitate control of the opening and closing state of the air inlets 112 and the size of the air inlet amount by operating the air inlet switch 113.
[0063] As Figure 11 , Figure 12 and Figure 15 , the outer wall surface of the atomizer base 12 is provided with two magnetic attraction members 123 at intervals, and the support structure 412 is also provided with two magnetic attraction members 123 at corresponding positions, the magnetic attraction members 123 of the atomizer base 12 and the magnetic attraction members 123 of the support structure 412 are in magnetic attraction connection to position and fix the atomizer 100, and also facilitate assembly and disassembly.
[0064] As Figures 3 to 5In the example, the atomization core assembly 3 of the atomizer 100 specifically includes an atomization cover 31, a liquid absorption structure 32, and a heating element 33. The atomization cover 31 forms an atomization cavity 312 inside, and one end of the atomization cover 31 is connected with the air outlet 111 of the shell 1, and the other end is sealingly connected with the sealing assembly 2. Specifically, a corresponding interface structure can be arranged inside the air outlet 111 to sealingly connect with one end of the atomization cover 31, and a corresponding connecting groove 222 is arranged on the sealing assembly 2 to sealingly connect with the other end of the atomization cover 31. The liquid absorption structure 32 is arranged on the inner side wall of the atomization cover 31, and can specifically adopt a hollow cylindrical structure. The heating element 33 adopts a heating mesh structure and is connected to the inner side wall of the liquid absorption structure 32. The atomization cover 31 is provided with a liquid inlet 311 at a position corresponding to the liquid absorption structure 32, and the atomization substrate in the liquid storage cavity 141 can pass through the liquid inlet 311 and be absorbed on the liquid absorption structure 32. The liquid absorption structure 32 can be made of liquid absorption cotton or the like, so that the atomization substrate can be uniformly absorbed on the liquid absorption structure 32. The heating element 33 has a pin structure 331, which passes through the air hole 2212 and is connected with the conductive element 122 on the atomizer base 12. The conductive element 122 is in contact with the conductive structure on the support structure 412 to be electrically connected with the power supply assembly 430. The heating element 33 can heat in the electrified state to heat the atomization substrate absorbed on the liquid absorption structure 32.
[0065] The connecting part of the sealing assembly 2 and the atomization cover 31 has a guide structure 221 protruding towards the atomization cavity 312. The guide structure 221 is a spherical structure and extends into the atomization cavity 312. A plurality of air holes 2212 are arranged on the spherical structure at a position close to the center in the circumferential direction. There is a liquid storage gap 2221 between the outer side wall edge of the guide structure 221 and the inner side wall of the atomization cavity 312. Correspondingly, the atomizer base 12 has a liquid storage groove at a position corresponding to the guide structure 221.
[0066] When the user performs a suction action through the mouthpiece structure 411, corresponding airflow movement is generated in the atomizer 100. Specifically, external air enters the air guide cavity 142 through the air inlet 112 and passes through the air holes 2212 on the guide structure 221 of the sealing assembly 2 to enter the atomization cavity 312 of the atomization core assembly 3. At the same time, the airflow sensor 422 senses the airflow movement and generates an induction signal. The electronic control board 432 receives the induction signal and controls the battery 431 to electrify the heating element 33 of the atomization core assembly 3. The heating element 33 heats to heat and atomize the atomization substrate in the atomization cavity 312. The generated aerosol mixes with the airflow entering the atomization cavity 312, and then flows to the outer port of the mouthpiece structure 411 under the action of the airflow.
[0067] In use, some condensate will be generated in the atomization cavity 312, and the liquid storage groove can accommodate the condensate from the atomization cavity 312 into the air guide cavity 142, and the guide structure 221 can guide part of the condensate in the atomization cavity 312 through the spherical structure, so that the part of the condensate flows to the liquid storage gap 2221, so as to prevent the part of the condensate from flowing directly through the air hole 2212 to the liquid storage groove below, thereby delaying the liquid accumulation speed of the liquid storage groove, preventing the liquid accumulation in the liquid storage groove from overflowing too fast to cause the condensate to enter the induction airway 121 or to leak outward, thereby preventing the adverse effects on the air flow inductor 422, prolonging the service life of the equipment, and at the same time, improving the use experience.
[0068] In addition, the atomization device 400 in the embodiment also has all the beneficial effects of the atomizer 100 in any of the above embodiments, which will not be repeated here.
[0069] The above application of specific examples is used to help understand the application and does not limit the application. For those skilled in the art to which the application belongs, according to the idea of the application, some simple deductions, deformations or substitutions can be made.
