[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 aerosols may have a burnt smell in the related art, and obtain the technical solutions of the embodiments of the present application through reasonable analysis.

[0034] In the related art, the atomizer is provided with a switching member to switch the atomizing medium in different liquid storage chambers to flow into the atomizing chamber, and the atomizer continuously consumes the atomizing medium in the liquid storage chamber to generate an aerosol for the user to inhale. In order to balance the air pressure difference between the liquid storage chamber and the outside world, the atomizer is provided with a ventilation channel to allow external gas to enter the liquid storage chamber. The bubbles generated by the ventilation channel covered by the liquid through hole can enter the liquid storage chamber through the liquid through hole, while the bubbles generated by the ventilation channel staggered from the liquid through hole are blocked by the switching member, which is easy to cause accumulation. When there are more bubbles, the bubbles will block part of the flow channel of the atomizing medium to flow to the atomizing core, making the atomizing medium not flowing smoothly, thereby causing the aerosol generated by the atomizing medium to have a burnt smell, which ultimately causes the user's experience to deteriorate.

[0035] On the one hand, the present application provides an aerosol generating device. Figures 1 to 8 , 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, nicotine-containing materials or nicotine-free materials, etc. The atomizing medium can be a solid material with plants such as tobacco as the main raw material and corresponding aerosol formers and aroma materials added. In one embodiment, the atomizing medium can be a 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 8 , the atomizer includes a shell 5, an atomizer seat 1, an atomizer core 10, a switching member 2 and an air guide 3. The shell 5 has a liquid storage chamber 1b, the liquid storage chamber 1b is used to store the atomizing medium, and the liquid storage chamber 1b includes a first liquid storage chamber and a second liquid storage chamber. The atomizer seat 1 has an atomizing chamber 1a, a first ventilation channel 1d and a second ventilation channel 1e. The atomizer seat 1 is connected to the shell 5. The first ventilation channel 1d connects the first liquid storage chamber with the atomizing chamber 1a, and the second ventilation channel 1e connects the second liquid storage chamber with the atomizing chamber 1a. The atomizer core 10 is fixed in the atomizing chamber 1a, and the atomizer core 10 is used to atomize the atomizing medium. The switching member 2 has a liquid hole 2a connecting the first liquid storage chamber and the atomizing chamber 1a, and the switching member 2 can cut off the communication path between the second liquid storage chamber and the atomizing chamber 1a. The switching member 2 is installed on the atomizer seat 1; and the air guide 3 is used to close the second ventilation channel 1e, and the air guide 3 is installed on the atomizer seat 1.

[0039] In this embodiment, the atomizer seat 1 is formed with an atomizing chamber 1a and a ventilation channel connected to the atomizing chamber 1a, and the air guide 3 is installed on the atomizer seat 1, and the air guide 3 is used to close the second ventilation channel 1e. The airflow in the atomizing chamber 1a forms bubbles after passing through the first ventilation channel 1d, and the bubbles enter the liquid storage chamber 1b through the liquid through hole 2a formed on the switching member 2, thereby balancing the air pressure difference between the liquid storage chamber 1b and the outside world. Furthermore, the switching member 2 can cut off the communication path between the second liquid storage chamber and the atomizing chamber 1a, and bubbles are difficult to be generated in the second ventilation channel 1e that is staggered with the liquid through hole 2a. Therefore, the atomizer of the embodiment of the present application causes bubbles to be generated in the ventilation channel corresponding to the liquid through hole 2a during the ventilation process, alleviates the situation of bubble accumulation, and the atomized medium flows smoothly to alleviate the situation of burnt smell of the aerosol generated by the aerosol generating device, thereby improving the user experience.

[0040] It can be understood that the first ventilation channel 1d is a ventilation channel covered by the liquid through hole 2a, and the second ventilation channel 1e is a ventilation channel staggered from the liquid through hole 2a.

[0041] It should be noted that the ventilation channel covered by the liquid through hole 2a refers to the projection along the up-down direction 1g, and the projection area of ​​the ventilation channel is located within the projection area of ​​the liquid through hole 2a.

[0042] It should be noted that the ventilation channel offset from the liquid through hole 2a refers to a projection area of ​​the ventilation channel along the up-down direction 1g, and the projection area of ​​the ventilation channel is located outside the projection area of ​​the liquid through hole 2a.

[0043] For example, see Figure 6 The switching member 2 is in the shape of a disc and is rotatably connected to the atomizer seat 1 . The switching member 2 is switched between various working positions by rotating relative to the atomizer seat 1 .

[0044] For example, see Figure 3 , multiple liquid storage chambers 1b are isolated from each other, and each liquid storage chamber 1b can accommodate atomized medium.

[0045] It is understandable that the atomized medium in each liquid storage chamber 1b can be of the same type or of different types.

[0046] In one embodiment, the atomizer core 10 includes a liquid-conducting body and a heating element. The liquid-conducting body is disposed in the atomizing chamber 1a, the heating element is disposed inside the liquid-conducting body, and the heating element is electrically connected to a power supply assembly.

[0047] Exemplarily, the material of the liquid conductor may be cotton or ceramic.

[0048] 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.

[0049] For example, see Figure 1 and Figure 3 The atomizer further includes a suction nozzle 4, which is mounted on the housing 5 and connected to the switching member 2. The suction nozzle 4 can rotate relative to the housing 5 to drive the switching member 2 to rotate. The suction nozzle 4 is formed with a suction channel 4a, which is connected to the inside of the atomizing seat 1, and the aerosol can enter the suction channel 4a from the atomizing seat 1.

[0050] Exemplarily, the housing 5 is also formed with an air inlet 1f, which is used to connect the outside with the inside of the atomizer seat 1. The airflow can enter the atomizer seat 1 from the air inlet 1f and flow to the inhalation channel 4a. The airflow can also enter the liquid storage chamber 1b from the atomizer seat 1 through the ventilation channel.

[0051] Exemplarily, the air inlet 1 f is formed at the bottom of the housing 5 .

[0052] In one embodiment, the atomizer and the power supply assembly are detachably connected.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] It is understandable that the present application is not limited to the detachable connection between the atomizer and the power assembly. In one embodiment, the atomizer is fixedly connected to the power assembly, and the atomizer and the power assembly are not detachable. In another embodiment, the atomizer core of the atomizer is fixedly connected to the power assembly, and the shell 5 of the atomizer is detachably connected to the atomizer seat 1, so that the atomized medium in the liquid storage chamber can be replaced after use, and the atomizer core can be removed together with the shell 5 to reduce the user's use cost.

[0057] In one embodiment, please refer to Figure 3 The air guide portion 3 includes at least two air guide components 30. The first ventilation channel 1d and the second ventilation channel 1e are each provided with an air guide component 30. The air guide component 30 can cut off the ventilation channel. When the air guide component 30 is located in the second ventilation channel 1e, the second ventilation channel 1e is in a closed state. The part of the air guide component 30 corresponding to the first ventilation channel 1d is located in the liquid hole 2a to open the first ventilation channel 1d.

[0058] It is understandable that when the air guide component 30 cuts off the ventilation channel, it is difficult for the air flow to flow through the corresponding ventilation channel.

[0059] In this embodiment, the air guide part 3 includes at least two air guide components 30, each of which corresponds to a ventilation channel. The individual control of each air guide component 30 can alleviate the mutual interference of the air guide part 3 in the process of ventilation channel, and the control of the air guide part 3 is more accurate and stable.

[0060] Exemplarily, the air guide component 30 corresponding to the first ventilation channel 1d is partially located in the liquid hole 2a so that the end of the corresponding air guide component 30 facing away from the switching element 2 is separated from the first ventilation channel 1d, so that the first ventilation channel 1d is in an open state.

[0061] Exemplarily, the air guide component 30 corresponding to the second air exchange channel 1e abuts against the switching member 2 and the atomizer seat 1 respectively to close the second air exchange channel 1e, and the air guide component 30 corresponding to the second air exchange channel 1e is pressed toward the second air exchange channel 1e under the action of the switching member 2.

[0062] It should be noted that the second ventilation channel 1e being in a closed state means that external gas cannot enter the liquid storage chamber through the second ventilation channel 1e.

[0063] It is understandable that the present application is not limited to the air guide portion 3 including at least two air guide components 30 to control the ventilation channels separately. In one embodiment, the air guide portion 3 also includes a connecting rod and a support rod, the support rod is arranged on the atomizer seat 1, the connecting rod is rotatably connected to the support rod, the air guide portion 3 has a plurality of air guide portions, the air guide portions are arranged corresponding to the ventilation channels, the two ends of the connecting rod are respectively connected to different air guide portions, and under the action of the connecting rod, the air guide portion can move into or out of the corresponding ventilation channel.

[0064] In one embodiment, please refer to Figure 4 and Figure 8 The air guide component 30 includes a latch 300 and a valve sleeve 301. The valve sleeve 301 is arranged on the atomizer seat 1. The latch 300 is movably arranged on the valve sleeve 301. The latch 300 penetrates the valve sleeve 301. When the switching member 2 abuts against the latch 300 corresponding to the second ventilation channel 1e, the end of the latch 300 away from the switching member 2 abuts against the second ventilation channel 1e to put the second ventilation channel 1e in a closed state. When the liquid hole 2a of the switching member 2 releases the latch 300 corresponding to the first ventilation channel 1d, the corresponding latch 300 is separated from the first ventilation channel 1d to put the first ventilation channel 1d in an open state.

[0065] In this embodiment, the air guide assembly 30 includes a latch 300 and a valve sleeve 301, the valve sleeve 301 is arranged on the atomizer seat 1, the latch 300 is movably arranged on the valve sleeve 301, and the latch 300 passes through the valve sleeve 301. Usually, in order to increase the overall strength of the atomizer, the atomizer seat 1 is made of hard plastic, the valve sleeve 301 can alleviate the friction between the atomizer seat 1 and the latch 300, and the movement of the latch 300 is smoother. Furthermore, the valve sleeve 301 can alleviate the wear of the latch 300 on the atomizer seat 1 during use. Exemplarily, the material of the valve sleeve 301 is silicone.

[0066] It is understandable that the embodiment of the present application is not limited to the air guide assembly 30 including the latch 300 and the valve sleeve 301. In one embodiment, the side wall of the latch 300 abuts against the atomizer seat 1 to alleviate the atomized medium from flowing from the vicinity of the latch 300 to the outside.

[0067] In one embodiment, the material of the latch 300 is oil-soakable plastic or silicone.

[0068] In this embodiment, the material of the latch 300 is oil-soakable plastic or silicone. The latch 300 itself can produce elastic deformation, so that the latch 300 can move into or out of the ventilation channel under the action of the switching member 2. The air guide component 30 does not need to be provided with additional components to drive the latch 300 to move. The air guide component 30 has a simple structure and is easy to assemble the atomizer.

[0069] It is understandable that the embodiment of the present application is not limited to the material of the latch 300 being oil-soakable plastic or silicone. In one embodiment, the air guide component 30 includes a latch 300 and a spring, the spring respectively abutting against the latch 300 and the atomizer seat 1, the spring can apply an elastic force toward the switching member 2 to the latch 300, and the latch 300 corresponding to the first ventilation channel 1d can open the corresponding ventilation channel under the action of the elastic force. The latch 300 can resist the elastic force of the spring under the action of the switching member 2 to put the corresponding ventilation channel in a closed state. In another embodiment, the air guide component 30 includes a magnetic member and a latch 300, the magnetic member is arranged on the atomizer seat 1, and the magnetic member can apply a magnetic force to the latch 300 to disengage the latch 300 from the ventilation channel, so that the corresponding ventilation channel is in an open state.

[0070] In one embodiment, the air guide portion 3 can cut off the second ventilation channel 1 e under the action of the switching element 2 .

[0071] In this embodiment, when the user uses the switching member 2 to switch the liquid storage chamber 1b, the air guide portion 3 can cut off the second ventilation channel 1e under the action of the switching member 2, which is more convenient for the user to operate and improves the user experience.

[0072] In one embodiment, please refer to Figure 6 and Figure 7 The switching member 2 is formed with a transition surface 2b, which is formed at both ends of the circumference of the liquid hole 2a. Along the circumference of the liquid hole 2a, the distance between one end of the transition surface 2b close to the liquid hole 2a and the bottom surface of the switching member 2 is greater than the distance between the other end and the bottom surface of the switching member 2.

[0073] In this embodiment, the switching member 2 is formed with a transition surface 2b, and the distance between one end of the transition surface 2b close to the liquid through hole 2a and the bottom surface of the switching member 2 is greater than the distance between the other end and the bottom surface of the switching member 2. During the movement of the switching member 2, the air guide 3 moves along the transition surface 2b, and the air guide 3 moves smoothly, which alleviates the impact of the air guide 3 during the process of separating from the switching member 2. Furthermore, during the process of the air guide 3 moving from the liquid through hole 2a to the transition surface 2b, the air guide 3 moves relatively smoothly.

[0074] It should be noted that the distance between any point on the transition surface 2 b and the bottom surface of the switching member 2 is the vertical distance between any point on the transition surface 2 b and the bottom surface of the switching member 2 .

[0075] Exemplarily, when the moving direction of the air guide assembly 30 is the up-down direction 1g, the distance between any point of the transition surface 2b and the bottom surface of the switching member 2 is the height difference between any point of the transition surface 2b and the bottom surface of the switching member 2.

[0076] Exemplarily, the transition surface 2b is formed at two ends of the liquid through hole 2a in the circumferential direction.

[0077] Exemplarily, the liquid through hole 2 a is in the shape of a circular ring, and the liquid through hole 2 a extends along the circumferential direction of the switching member 2 .

[0078] In one embodiment, the transition surface 2b is a curved surface.

[0079] In this embodiment, the transition surface 2 b is a curved surface, which makes the movement of the air guide component 30 smoother and alleviates the interference between the air guide component 30 and the switching component 2 .

[0080] It is understandable that the present application is not limited to the transition surface 2b being formed on the switching member 2. In one embodiment, the transition surface 2b is formed on one end of the latch 300 facing the switching member 2.

[0081] It is understandable that, projected along the length direction of the latch 300, the projected area of ​​the latch 300 is smaller than the projected area of ​​the switch member 2. When the stroke of the latch 300 is constant, the slope formed by the transition surface 2b formed on the switch member 2 is smaller than the slope formed by the transition surface 2b formed on the latch 300. When the switch member 2 acts on the latch 300, the force that needs to be applied changes slowly, and the user's experience is better.

[0082] In one embodiment, please refer to Figure 8 A guide surface 300 a is formed at one end of the latch 300 facing the switching member 2 , and one end of the guide surface 300 a facing the central axis of the latch 300 is higher than the other end.

[0083] In this embodiment, when the latch 300 abuts against the transition surface 2 b , the guide surface 300 a cooperates with the transition surface 2 b , which can further alleviate the interference between the latch 300 and the switching member 2 , making the movement process smoother.

[0084] In one embodiment, please refer to Figure 7 Along the circumference of the liquid through hole 2a, the difference between the height of the end of the transition surface 2b facing the liquid through hole 2a and the height of the end away from the liquid through hole 2a ranges from 0.1mm to 2.0mm.

[0085] In this embodiment, the difference between the height of the end of the transition surface 2b facing the liquid hole 2a and the height of the end away from the liquid hole 2a is in the range of 0.1mm to 2.0mm. The difference between the heights within a suitable range can ensure that the ventilation channel is easy to process, the overall size of the atomizer is compressed as much as possible, and the switching member 2 is easier during the switching process. Furthermore, the gap between the plug 300 and the ventilation channel due to the processing tolerance problem of the ventilation channel can be alleviated.

[0086] Exemplarily, the difference between the height of one end of the transition surface 2b facing the liquid hole 2a and the height of the other end away from the liquid hole 2a is 0.1mm, 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.1mm, 1.3mm, 1.5mm, 1.7mm, 1.9mm or 2.0mm.

[0087] In one embodiment, please refer to Figure 7 The angle formed between the transition surface 2b and the rotation plane of the switching member 2 is in the range of 1° to 45°.

[0088] In this embodiment, the angle formed between the transition surface 2b and the rotation plane of the switching member 2 is within a suitable range, the movement of the air guide portion 3 is smoother, and the user can switch conveniently.

[0089] It should be noted that the embodiment of the present application does not limit the direction of the rotation plane of the switching member 2. The rotation plane of the switching member 2 can be a horizontal plane, or a plane that forms an angle with the horizontal plane.

[0090] Exemplarily, the angle formed between the transition surface 2 b and the rotation plane of the switching element 2 is 1°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40° or 45°.

[0091] In one embodiment, please refer to Figure 5 The liquid storage chamber 1b, the liquid through hole 2a and the atomizing core 10 are arranged from top to bottom.

[0092] In this embodiment, the liquid storage chamber 1b, the liquid through hole 2a and the atomizing core 10 are arranged from top to bottom, and the atomizing medium in the liquid storage chamber 1b can smoothly pass through the liquid through hole 2a from the liquid storage chamber 1b to contact the atomizing core 10 by its own gravity, so as to be atomized into an aerosol. The arrangement direction is basically parallel to the gravity direction, and the atomizing medium flows smoothly, which can ensure that the atomizing medium in the atomizing chamber 1a can be basically maintained in a saturated state, and alleviate the situation where the aerosol has a burnt smell.

[0093] Exemplarily, the liquid storage chamber 1 b , the liquid through hole 2 a and the atomizing core 10 are arranged in a straight line.

[0094] In one embodiment, please refer to Figure 3 and Figure 4 The switching member 2 and the air guide portion 3 are arranged along the up-down direction 1g, and the air guide portion 3 can move along the up-down direction 1g to move into or out of the ventilation channel.

[0095] In this embodiment, the switching member 2 and the air guide portion 3 are arranged along the up-down direction 1g, and the air guide portion 3 moves along the up-down direction 1g.
