DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions.

[0032] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the reasons why users inhale liquids in the relevant technology, and obtain the technical solutions of the embodiments of the present application through reasonable analysis.

[0034] In the related art, the atomizer heats the atomizing medium in the atomizing chamber to form an aerosol, and the aerosol is then inhaled by the user through the mouthpiece. During the inhalation process, there is a situation where the user does not completely inhale the aerosol in the atomizing chamber, and the aerosol will remain in the atomizing chamber. After the atomizer stops heating, the temperature in the atomizing chamber drops, and the aerosol remaining in the atomizing chamber will form condensate. Usually, a liquid absorption component is provided in the atomizer to absorb the condensate, but the liquid absorption component will also absorb the newly generated aerosol during the user's inhalation of the aerosol, thereby reducing the user's inhalation amount.

[0035] On the one hand, the present application provides an aerosol generating device. Figures 1 to 4 , including a power supply assembly and an atomizer provided by any embodiment of the present application. The power supply assembly is electrically connected to the atomizer.

[0036] The aerosol generating device is used to atomize the atomizing medium to generate an aerosol for the smoker to inhale. The atomizing medium includes but is not limited to medicines, materials containing nicotine or materials not containing nicotine, etc. In one embodiment, the atomizing medium can be liquid oil containing nicotine.

[0037] The power supply assembly is electrically connected to the atomizer for supplying power to the atomizer. The atomizer converts the electrical energy into thermal energy, and the aerosol generating matrix is ​​converted into an aerosol that can be inhaled by the user under the action of the thermal energy.

[0038] Another aspect of the present application embodiment provides an atomizer, see Figures 1 to 6 , the atomizer includes a shell 1, an atomizer seat 6, a liquid suction component 3 and an atomizer core 4. The shell 1 has a liquid storage chamber and an outlet flow channel 1b isolated from each other, and the liquid storage chamber is used to store the atomized medium. The atomizer seat 6 is connected to the shell 1, and the atomizer seat 6 includes an atomizer seat body 2 and a block 5. The atomizer seat body 2 has an air inlet 2a. The liquid suction component 3 is arranged on the atomizer seat 6, and the liquid suction component 3, the block 5 and the atomizer seat body 2 are surrounded to form an atomizing chamber 2b that is connected to the air inlet 2a and the air outlet respectively. The outlet flow channel 1b is located on the downstream side of the atomizing chamber 2b, and the air inlet 2a is located on the upstream side of the atomizing chamber 2b. The liquid suction component 3 has a first liquid suction part 30a, and the atomizing chamber 2b includes a guide chamber 2d for guiding the airflow of the air inlet 2a to the outlet flow channel 1b. The first liquid suction part 30a, the block 5 and the atomizer seat body 2 are jointly surrounded to form the guide chamber 2d. The atomizing core 4 is fixed in the atomizing chamber 2b. The atomizing core 4 is connected to the liquid storage chamber and is used to atomize the atomizing medium to form an aerosol. The block 5 is located on the side of the atomizing core 4 facing the first liquid suction part 30a. The aerosol generated by the atomizing core 4 passes through the block 5, the first liquid suction part 30a and the outlet channel 1b in sequence.

[0039] In this embodiment, the liquid absorption assembly 3, the atomizer seat body 2 and the block 5 are arranged to form an atomizing chamber 2b, and the atomizing chamber 2b is connected to the air inlet 2a and the outlet flow channel 1b. The first liquid absorption part 30a of the liquid absorption assembly 3 can absorb the condensed water remaining in the atomizing chamber 2b, and also absorb a part of the aerosol during the user's aerosol inhalation process. The block 5 is arranged on the side of the atomizing core 4 facing the first liquid absorption part 30a to reduce the adsorption of the aerosol by the first liquid absorption part 30a, thereby reducing the situation where the aerosol becomes less, and improving the user's experience. Furthermore, the block 5 is located in the guide cavity 2d, which can reduce the flow space in the guide cavity 2d, and reduce the vortex formed by the airflow flowing in the guide cavity 2d, so that the aerosol can enter the outlet flow channel 1b more smoothly with the airflow.

[0040] Exemplarily, the inlet passage 2a and the outlet passage 1b are arranged along the up-down direction 2c.

[0041] Exemplarily, the material of the liquid absorbent component 3 is liquid absorbent cotton.

[0042] In one embodiment, the atomizing seat 6 is further formed with a ventilation channel, and the ventilation channel connects the atomizing chamber 2b and the liquid storage chamber.

[0043] In this embodiment, the ventilation channel connects the atomizing chamber 2b and the liquid storage chamber. The airflow enters the atomizing chamber 2b from the air inlet 2a and then enters the liquid storage chamber through the ventilation channel to balance the air pressure difference between the liquid storage chamber and the outside world, so that the atomized medium can flow out of the liquid storage chamber stably.

[0044] In one embodiment, the atomizer core 4 includes a liquid-conducting liquid and a heating element. The liquid-conducting liquid is disposed in the atomizing chamber 2b, the heating element is disposed inside the liquid-conducting liquid, and the heating element is electrically connected to a power supply assembly.

[0045] Exemplarily, the material of the liquid conductor may be cotton or ceramic.

[0046] In this embodiment, the power supply component provides electrical energy to the heating element, and the heating element can convert the electrical energy into thermal energy, thereby heating the atomizing medium to form an aerosol.

[0047] In one embodiment, the atomizer and the power supply assembly are detachably connected.

[0048] In this embodiment, the atomizer is an independent component, and a new atomizer can be replaced after the atomization medium in the liquid storage chamber is used up.

[0049] It should be noted that there is no limit to the detachable connection method between the power supply assembly and the atomizer, for example, it can be a magnetic connection, a snap connection, a threaded connection or a plug-in connection.

[0050] In one embodiment, the atomizer and the power supply assembly are connected by magnetic attraction. The magnetic attraction connection between the atomizer and the power supply assembly can improve the reliability and convenience of the connection between the atomizer and the power supply assembly.

[0051] It is understandable that the present application is not limited to the detachable connection between the atomizer and the power supply assembly. In one embodiment, the atomizer is fixedly connected to the power supply assembly, and the atomizer and the power supply assembly are not detachable. In another embodiment, the atomizer core 4 of the atomizer is fixedly connected to the power supply assembly, and the shell 1 of the atomizer is detachably connected to the atomizer seat 6, so that the atomized medium in the liquid storage chamber can be replaced after use, and the atomizer core 4 can be not disassembled together with the shell 1 to reduce the user's use cost.

[0052] In one embodiment, please refer to Figure 3 and Figure 4 The liquid absorption component 3 is partially arranged around the atomization core 4.

[0053] It should be noted that the liquid absorption component 3 is partially disposed around the atomizer core 4 and is not limited to being continuous along the circumference of the atomizer core 4 , and the liquid absorption component 3 may also be discontinuous.

[0054] In this embodiment, the liquid absorption component 3 is partially arranged around the atomizing core 4, and the contact area between the liquid absorption component 3 and the aerosol is large, so the liquid absorption component 3 can better absorb the condensed water formed by the aerosol. Furthermore, the volume of the liquid absorption component 3 is large, and it can absorb more condensed water, which alleviates the situation where the user frequently replaces the liquid absorption component 3 because the liquid absorption component 3 is saturated.

[0055] In one embodiment, please refer to Figure 5Along the arrangement direction of the outlet flow channel 1b and the atomizer core 4, the surface of the block 5 facing the outlet flow channel 1b is the first surface 5a, and the surface of the atomizer core 4 away from the outlet flow channel 1b is the second surface 4a. The first surface 5a is located between the outlet flow channel 1b and the second surface 4a.

[0056] In this embodiment, the first surface 5a is located between the outlet channel 1b and the second surface 4a, and is projected along the arrangement direction of the block 5 and the atomizer core 4. The projection area of ​​the block 5 can cover more of the projection area of ​​the atomizer core 4, and the block 5 can better block the aerosol.

[0057] In one embodiment, please refer to Figure 4 The liquid absorption component 3 includes a first liquid absorption component 30 and a second liquid absorption component 31. The first liquid absorption component 30 and the second liquid absorption component 31 are both arranged on the atomizer seat body 2. The first liquid absorption component 30 is arranged around the side of the atomizer core 4. The first liquid absorption portion 30a is formed on the side of the first liquid absorption component 30 facing the atomization chamber 2b. The second liquid absorption component 31 is located on the side of the first liquid absorption component 30 away from the outlet channel 1b, and the second liquid absorption component 31 is attached to the first liquid absorption component 30.

[0058] In this embodiment, the liquid absorption component 3 includes a first liquid absorption component 30 and a second liquid absorption component 31. The first liquid absorption component 30 is arranged around the side of the atomizing core 4, and the second liquid absorption component 31 is attached to the first liquid absorption component 30. The first liquid absorption component 30 is arranged on the side of the atomizing core 4, and the first liquid absorption component 30 can better absorb the condensed water in the atomizing chamber 2b. The second liquid absorption component 31 is arranged on the side of the first liquid absorption component 30 away from the first opening, and the space on the bottom surface of the atomizing chamber 2b is more fully utilized. The liquid absorbed by the first liquid absorption component 30 can be transferred to the second liquid absorption component 31 attached to the first liquid absorption component 30, and the liquid absorption component 3 can absorb more liquid. Thereby alleviating the situation that the liquid absorption component 3 needs to be frequently replaced because the absorbed liquid reaches saturation.

[0059] In one embodiment, please refer to Figure 4 The top surface of the second liquid-absorbing component 31 is attached to the bottom surface of the first liquid-absorbing component 30 .

[0060] In this embodiment, after the first liquid absorbent member 30 absorbs liquid, the absorbed liquid can be transferred to the second liquid absorbent member 31 due to its own gravity, so that it is difficult for the first liquid absorbent member 30 to reach saturation.

[0061] In one embodiment, the second absorbent member 31 and the first absorbent member 30 are integrally formed.

[0062] In this embodiment, the second liquid absorbing member 31 and the first liquid absorbing member 30 are integrally formed, which reduces the assembly steps of the liquid absorbing assembly 3 and makes the processing of the atomizer more convenient.

[0063] It is understandable that the present application is not limited to the second liquid absorbing member 31 and the first liquid absorbing member 30 being integrally formed. In one embodiment, the second liquid absorbing member 31 and the first liquid absorbing member 30 are processed separately, and after the second liquid absorbing member 31 and the first liquid absorbing member 30 are processed separately, the second liquid absorbing member 31 and the first liquid absorbing member 30 are connected to the atomizing seat 6 respectively.

[0064] In one embodiment, please refer to Figure 3 and Figure 4 The atomizing chamber 2b includes a guide chamber 2d for guiding the airflow of the air inlet channel 2a to the outlet channel 1b. The second liquid absorption member 31 has a second liquid absorption portion 31a. The first liquid absorption portion 30a, the second liquid absorption portion 31a and the atomizing seat 6 are arranged to form the guide chamber 2d. The first liquid absorption portion 30a is located on the side of the atomizing core 4 facing the guide chamber 2d.

[0065] Exemplarily, the second liquid suction portion 31a is formed below the flow guiding cavity 2d.

[0066] In this embodiment, the atomizing chamber 2b includes a guide chamber 2d for guiding the airflow of the air inlet 2a to the outlet flow channel 1b, and the first liquid absorption portion 30a is located on the side of the atomizing core 4 facing the guide chamber 2d. The guide chamber 2d is used to guide the airflow, and the residual aerosol may remain in the guide chamber 2d. The first liquid absorption portion 30a is located on the side of the atomizing core 4 facing the guide chamber 2d. The first liquid absorption portion 30a can absorb the condensed water formed in the guide chamber 2d more stably. This further alleviates the situation where the condensed water is inhaled into the mouth of the user.

[0067] In one embodiment, please refer to Figure 4 , the stopper 5 is in contact with the first liquid absorbing part 30a.

[0068] In this embodiment, the block 5 is in contact with the first liquid absorbing part 30a, and the block 5 can play a good blocking role, reduce the aerosol absorbed by the first liquid absorbing part 30a, and can effectively reduce the vortex formed by the airflow in the guide cavity 2d.

[0069] It is understandable that the present application is not limited to the block 5 being in contact with the first liquid absorbing portion 30a. In one embodiment, along the arrangement direction of the first liquid absorbing portion 30a and the atomizer core 4, the block 5 and the first liquid absorbing portion 30a are arranged at intervals.

[0070] Exemplarily, along the arrangement direction of the first liquid absorption part 30a and the atomizer core 4, the distance between the stopper 5 and the first liquid absorption part 30a ranges from 0 mm to 1.5 mm.

[0071] Exemplarily, along the arrangement direction of the first liquid absorption portion 30a and the atomizer core 4, the distance between the stopper 5 and the first liquid absorption portion 30a is 0 mm, 0.5 mm, 1.0 mm or 1.5 mm.

[0072] It is understandable that, along the arrangement direction of the first liquid absorption part 30a and the atomizer core 4, the distance between the stopper 5 and the first liquid absorption part 30a can be measured by a ruler or a vernier caliper at normal temperature and pressure before the atomizer is heated for the first time.

[0073] In one embodiment, please refer to Figure 4 , the stopper 5 is in contact with the second liquid absorbing part 31a.

[0074] In this embodiment, the stopper 5 is in close contact with the second liquid absorbent portion 31 a , which can reduce the situation where the airflow carries the aerosol and flows from the bottom of the stopper 5 to the first liquid absorbent member 30 .

[0075] It is understandable that the embodiment of the present application is not limited to the stopper 5 being in contact with the second liquid absorbing part 31a. In one embodiment, along the up-down direction 2c, the stopper 5 and the second liquid absorbing part 31a are arranged at intervals.

[0076] In one embodiment, the stopper 5 is connected to the atomizer seat body 2 .

[0077] In this embodiment, the stopper 5 is connected to the atomizer seat body 2, and the stopper 5 is stably positioned in the flow guide cavity 2d, and can play a good blocking role.

[0078] Exemplarily, the stopper 5 is fixedly connected to the atomizer seat body 2 .

[0079] In one embodiment, the arrangement of the stopper 5 satisfies at least one of the following:

[0080] The stopper 5 is in contact with the first liquid suction part 30a;

[0081] The stopper 5 is in contact with the second liquid absorbing part 31a.

[0082] In one embodiment, along the arrangement direction of the outlet channel 1b and the air inlet channel 2a, the distance between the surface of the stopper 5 facing the outlet channel 1b and the surface of the atomizer seat body 2 facing the air inlet channel 2a ranges from 3 mm to 5 mm.

[0083] In this embodiment, along the arrangement direction of the outlet flow channel 1b and the air inlet channel 2a, the distance between the surface of the block 5 facing the outlet flow channel 1b and the surface of the atomizer seat body 2 facing the air inlet channel 2a is within a suitable range, which can take into account the area of ​​the aerosol blocked by the block 5 and the area of ​​the first liquid absorbing part 30a exposed to the guide cavity 2d. Therefore, the block 5 can better reduce the vortex formed by the corner of the airflow at the first liquid absorbing part 30, and the first liquid absorbing part 30a can absorb the liquid in the guide cavity 2d more stably.

[0084] Exemplarily, the distance between the top surface of the stopper 5 and the atomizer seat 6 is 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm or 5.0 mm.

[0085] It is understandable that the distance between the top surface of the stopper 5 and the atomizer seat 6 along the up-down direction 2c can be measured by a ruler or a vernier caliper at normal temperature and pressure before the atomizer is heated for the first time.

[0086] In one embodiment, please refer to Figure 4 The direction intersecting the up-down direction 2c is a preset direction 3a, and the flow guide cavity 2d is arranged on opposite sides of the atomization core 4 along the preset direction 3a.

[0087] Exemplarily, the preset direction 3a is arranged orthogonal to the up-down direction 2c.

[0088] In this embodiment, the flow guiding cavity 2d is arranged along the preset direction 3a on opposite sides of the atomizer core 4, and the airflow can flow to the outlet flow channel 1b from opposite sides of the atomizer core 4. The user can absorb more aerosol within a certain period of time, which can enhance the user's experience.

[0089] It is understandable that the present embodiment is not limited to the flow guiding chamber 2d being arranged on opposite sides of the atomizing chamber 2b along the preset direction 3a. In one embodiment, the flow guiding chamber 2d is located on one side of the atomizing chamber 2b along the preset direction 3a.

[0090] In one embodiment, please refer to Figure 4 The atomizing core 4 is provided with first liquid absorbing parts 30a on opposite sides along the preset direction 3a.

[0091] In this embodiment, the first liquid absorption part 30a is correspondingly arranged on both sides of the atomizing core 4 along the preset direction 3a, and the aerosol flows from the opposite sides of the atomizing core 4 along the airflow, thereby contacting the first liquid absorption parts 30a on both sides. The first liquid absorption part 30a can absorb the liquid remaining in the guide cavity 2d on both sides, thereby reducing the situation where the liquid continues to remain in the atomizing cavity 2b.

[0092] In one embodiment, a stopper 5 is correspondingly disposed on each side of the first liquid suction portion 30a.

[0093] In this embodiment, a stopper 5 is correspondingly provided on each side of the first liquid absorption part 30a, and the stopper 5 can largely block the absorption of aerosol by the liquid absorption component 3 in the guide cavity 2d, thereby reducing the user experience caused by the absorption of aerosol by the liquid absorption component 3.

[0094] Exemplarily, the atomizer seat body 2 is formed with a mounting cavity 2e, and the mounting cavity 2e is used to mount the atomizer core 4 therein.

[0095] In one embodiment, please refer to Figure 6A leakage groove 2f is formed on the cavity wall of the installation cavity 2e, and the bottom wall of the leakage groove 2f is the third surface 2g. The surfaces of the side wall of the installation cavity 2e that are away from the outlet flow channel 1b except the third surface 2g are all located on the side of the third surface 2g facing the air inlet channel 2a, and the arrangement direction of the atomization core 4 and the leakage groove 2f is cross-arranged with the arrangement direction of the atomization cavity 2b and the guide cavity 2d.

[0096] In this embodiment, the surface of the side wall of the installation cavity 2e facing the outlet flow channel 1b is located on the side of the third surface 2g facing the air inlet channel 2a, and the arrangement direction of the atomizer core 4 and the leakage groove 2f is arranged crosswise with the arrangement direction of the atomizer cavity 2b and the flow guide cavity 2d. During the transportation of the atomizer, the atomizer is usually in an inverted state, and the atomizer core 4 is easily squeezed by the atomizer seat body 2 during transportation, so that the atomized medium flows to the atomizer cavity 2b, and the third surface 2g is lower, and the atomized medium will flow more to the leakage groove 2f, thereby reducing the atomized medium from entering the flow guide cavity 2d, and thus remaining in the mouthpiece, affecting the user's feeling of use.

[0097] In one embodiment, please refer to Figure 6 At least one of the side walls of the mounting cavity 2e is formed with a capillary groove 2i, the groove wall of the capillary wall 2h is in contact with the liquid absorption component 3, and the capillary groove 2i is used to allow the atomization medium to flow toward the atomization core 4.

[0098] In this embodiment, the cavity wall of the mounting cavity 2e is formed with a capillary groove 2i, and the capillary groove 2i abuts against the liquid absorption component 3. When the user uses the atomizer, the liquid absorption component 3 absorbs a portion of the aerosol or atomized medium, and the atomized medium can return to the atomization core 4 through the capillary groove 2i for heating, thereby increasing the user's use experience.

[0099] It can be understood that the size of the capillary groove 2i is configured to be a size capable of generating a capillary phenomenon.
