Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, and more particularly to an aerosol generating device. Background Technology

[0002] An aerosol generator is a product that can turn a liquid atomized matrix into an aerosol through heating or other means.

[0003] When the aerosol generator is evacuated, gas enters the aerosol generator through the inlet and generates an airflow. The airflow flows through the atomization channel in the aerosol generator and carries the aerosols in the atomization channel out of the aerosol generator. However, the airflow inside the aerosol generator is quite noisy, especially in quiet environments, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this application is to provide an aerosol generating device that aims to reduce the noise generated when the aerosol generating device is being drawn in.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: an aerosol generating device, including a housing assembly, an atomizing assembly, and a control assembly.

[0006] The housing assembly comprises a liquid storage chamber, a buffer chamber, and a mounting chamber arranged in sequence, with the liquid storage chamber communicating with the buffer chamber. An atomizing component is housed in and communicates with the liquid storage chamber, and the atomizing component has an atomizing channel penetrating the liquid storage chamber and communicating with the buffer chamber. A control component is housed in the mounting chamber and electrically connected to the atomizing component. The housing assembly also includes a first vent and an air inlet, the first vent communicating with the buffer chamber and the mounting chamber, and the air inlet communicating with the mounting chamber and the external space. At least one of the first vent and the air inlet is provided in multiple locations.

[0007] The beneficial effects of the aerosol generating device provided in this application embodiment are as follows: Since the shell assembly is constructed with a liquid storage chamber, a buffer chamber, and a mounting chamber stacked sequentially, and the liquid storage chamber is provided with an atomizing channel communicating with the buffer chamber; the shell assembly is also provided with a first air passage and an air inlet, the first air passage connecting the buffer chamber and the mounting chamber, and the air inlet connecting the mounting chamber and the external space; therefore, when the aerosol generating device is drawn in, the airflow direction is: air inlet → mounting chamber → first air passage → buffer chamber → atomizing channel. The airflow first fills the buffer chamber before entering the atomizing channel. After the airflow diffuses in the buffer chamber, it can enter the atomizing channel with a more uniform speed and pressure, reducing local turbulence, making the airflow entering the atomizing channel continuous and stable. Furthermore, the buffer chamber can absorb the impact of the airflow, thereby reducing the turbulence noise and mechanical vibration generated when high-speed airflow directly enters the atomizing channel, improving the quietness of the aerosol generating device, and reducing the noise generated when the aerosol generating device is drawn in. Furthermore, since at least one of the first air passage and the air inlet is provided with multiple holes, the multiple holes can break a strong turbulence into several weak turbulences, achieving a silent effect. Therefore, the quietness of the aerosol generating device can be improved, and the noise generated when the aerosol generating device is being drawn in can be reduced.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0024] An aerosol generator is a product that can turn a liquid atomized matrix into an aerosol through heating or other means.

[0025] When the aerosol generator is evacuated, gas enters the aerosol generator through the inlet and generates an airflow. The airflow flows through the atomization channel in the aerosol generator and carries the aerosols in the atomization channel out of the aerosol generator. However, the airflow inside the aerosol generator is quite noisy, especially in quiet environments, resulting in a poor user experience.

[0026] In view of the above problems, this application provides an aerosol generating device, which aims to reduce the noise generated when the aerosol generating device is being drawn in.

[0027] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0028] Please refer to Figures 1 to 2 This application provides an aerosol generating device, including a housing assembly 100, an atomizing assembly 200, and a control assembly 300.

[0029] The housing assembly 100 comprises a liquid storage chamber 110, a buffer chamber 120, and a mounting chamber 130 arranged in sequence. The liquid storage chamber 110 communicates with the buffer chamber 120. An atomizing assembly 200 is housed in and communicates with the liquid storage chamber 110. The atomizing assembly 200 has an atomizing channel 210 penetrating the liquid storage chamber 110 and communicating with the buffer chamber 120. A control assembly 300 is housed in the mounting chamber 130 and electrically connected to the atomizing assembly 200. The housing assembly 100 also includes a first vent 140 and an air inlet 150. The first vent 140 communicates with the buffer chamber 120 and the mounting chamber 130, and the air inlet 150 communicates with the mounting chamber 130 and the external space. At least one of the first vent 140 and the air inlet 150 is provided in multiple quantities.

[0030] Understandably, the mounting cavity 130, buffer cavity 120, and liquid storage cavity 110 are typically stacked sequentially from bottom to top. The mounting cavity 130 is used to accommodate the control assembly 300. A gap exists between the control assembly 300 and the inner wall of the mounting cavity 130 to allow airflow within the mounting cavity 130. For example, Figure 2 As shown, the housing assembly 100 includes a base 170 and a cup body 161. The base 170 is housed within the cup body 161, and the base 170 and the cup body 161 together form a mounting cavity 130. A control assembly 300 is mounted on the base 170 and housed within the mounting cavity 130. The control assembly 300 is spaced apart from the base 170 and from the inner wall of the cup body 161, allowing airflow to flow within the mounting cavity 130.

[0031] It is understood that the atomizing component 200 is housed in and communicates with the liquid storage chamber 110. The atomizing component 200 is constructed with an atomizing channel 210 that penetrates the liquid storage chamber 110, meaning that the aerosol generating matrix stored in the liquid storage chamber 110 can enter the atomizing component 200. When the atomizing component 200 is in operation, the aerosol generating matrix entering the atomizing component 200 can be atomized by the atomizing component 200 to generate aerosols within the atomizing channel 210.

[0032] Since the atomizing channel 210 is connected to the buffer chamber 120, when the aerosol generating device is drawn in, the airflow first fills the buffer chamber 120 before entering the atomizing channel 210. After the airflow diffuses in the buffer chamber 120, it can enter the atomizing channel 210 at a more uniform speed and pressure, reducing the possibility of local turbulence. This makes the airflow entering the atomizing channel 210 continuous and stable. Furthermore, the buffer chamber 120 can absorb the impact of the airflow, thereby reducing the turbulence noise and mechanical vibration generated when high-speed airflow directly enters the atomizing channel 210, improving the quietness of the aerosol generating device, and reducing the noise generated when the aerosol generating device is drawn in.

[0033] It is understood that the control component 300 is electrically connected to the atomizing component 200, that is, the control component 300 is used to supply power to the atomizing component 200, and the control component 300 is used to control the working state of the atomizing component 200 (whether it is working, the working power, etc.). For example, the control component 300 includes an airflow sensing switch, a circuit board 310, and a battery 320. The airflow sensing switch is located at the mounting cavity 130. When the airflow rate in the mounting cavity 130 reaches the response threshold of the airflow sensing switch, the battery 320 supplies power to the atomizing component 200, and the circuit board 310 controls the atomizing component 200 to work to generate aerosol in the atomization channel 210.

[0034] It is understood that the housing assembly 100 is also provided with a first vent 140 and an air inlet 150. The first vent 140 connects the buffer chamber 120 and the mounting chamber 130, and the air inlet 150 connects the mounting chamber 130 and the external space. That is, when the aerosol generating device is drawn in, the airflow direction is: air inlet 150 → mounting chamber 130 → first vent 140 → buffer chamber 120 → atomization channel 210.

[0035] Understandably, when multiple first vents 140 are provided, the multiple first vents 140 can break down the strong turbulence entering the buffer chamber 120 into several weak turbulences, which can disperse the energy of the airflow and balance the air pressure in the buffer chamber 120. Furthermore, the multiple first vents 140 allow the airflow entering the buffer chamber 120 to diffuse rapidly and cancel each other out, enabling the air pressure in the buffer chamber 120 to quickly reach uniformity. This avoids local high-pressure and low-pressure areas caused by direct airflow from a single vent, thereby reducing turbulent noise and mechanical vibration generated when the airflow enters the buffer chamber 120, improving the quietness of the aerosol generating device, and reducing the noise generated when the aerosol generating device is being drawn in.

[0036] Understandably, when multiple air inlets 150 are provided, the strong turbulence entering the mounting cavity 130 can be broken down into several weak turbulences, dispersing the energy of the airflow and balancing the air pressure within the mounting cavity 130. Furthermore, the multiple air inlets 150 allow the airflow entering the mounting cavity 130 to diffuse rapidly and cancel each other out, enabling the air pressure within the mounting cavity 130 to quickly reach uniformity. This avoids localized high-pressure and low-pressure areas caused by direct airflow from a single inlet, thereby reducing turbulent noise and mechanical vibration generated when the airflow enters the mounting cavity 130, improving the quietness of the aerosol generating device, and reducing the noise generated when the aerosol generating device is being drawn in.

[0037] It is understandable that having multiple first air vents 140 and air inlets 150 can improve the effect of reducing noise generated when the aerosol generating device is being drawn in.

[0038] In the aerosol generating device provided in this application embodiment, since the shell assembly 100 is constructed with a liquid storage chamber 110, a buffer chamber 120 and a mounting chamber 130 stacked in sequence, and the liquid storage chamber 110 is provided with an atomization channel 210 communicating with the buffer chamber 120; the shell assembly 100 is also provided with a first air passage 140 and an air inlet 150, the first air passage 140 communicating with the buffer chamber 120 and the mounting chamber 130, and the air inlet 150 communicating with the mounting chamber 130 and the external space; therefore, when the aerosol generating device is drawn in, the airflow direction is: air inlet 150 → mounting chamber 130 → first air passage 140 → buffer chamber 120 → atomization channel 210. The airflow first fills the buffer chamber 120 before entering the atomization channel 210. After diffusing within the buffer chamber 120, the airflow enters the atomization channel 210 at a more uniform speed and pressure, reducing local turbulence and making the airflow entering the atomization channel 210 continuous and stable. Furthermore, the buffer chamber 120 absorbs the impact of the airflow, thereby reducing turbulence noise and mechanical vibration generated when high-speed airflow directly enters the atomization channel 210, improving the quietness of the aerosol generating device, and reducing the noise generated when the aerosol generating device is being drawn in. Since at least one of the first air passage 140 and the air inlet 150 has multiple holes, the multiple holes can break down a strong turbulent flow into several weak turbulent flows, achieving a quieting effect. Therefore, it can improve the quietness of the aerosol generating device and reduce the noise generated when the aerosol generating device is being drawn in.

[0039] In some embodiments, a plurality of first air passages 140 are provided, and the plurality of first air passages 140 are symmetrically arranged around the central axis of the atomization channel 210.

[0040] In the above embodiment, the multiple first air passages 140 are geometrically symmetrical, allowing airflow to enter the buffer chamber 120 simultaneously, in equal amounts, and at equal speeds. This creates an isobaric ring in the circumferential direction, preventing local high-pressure or low-pressure zones within the buffer chamber 120 and balancing the air pressure within it. Furthermore, the momentum of the airflow entering the buffer chamber 120 through the multiple first air passages 140 cancels each other out, allowing the air pressure within the buffer chamber 120 to quickly reach uniformity. This achieves the "rectification-pressure equalization" function within a very short path, reducing turbulent noise and mechanical vibration generated when airflow enters the buffer chamber 120, improving the quietness of the aerosol generation device, and reducing the noise generated when the aerosol generation device is being drawn in.

[0041] Please refer to Figure 2 In some embodiments, there are two first air passages 140, which are arranged 180° apart around the central axis of the atomization channel 210.

[0042] In other embodiments, the number of first air passages 140 can be N (N is greater than 2), and the N first air passages 140 are arranged at a first angle interval around the coaxial line of the atomization channel 210, where the first angle = 360° / N.

[0043] In some embodiments, multiple air inlets 150 are provided, and the multiple air inlets 150 are symmetrically arranged around the central axis of the atomizing channel 210.

[0044] In the above embodiment, the multiple air inlets 150 are geometrically symmetrical, allowing airflow to enter the mounting cavity 130 simultaneously, in equal amounts, and at equal speeds. This creates an isobaric ring in the circumferential direction, preventing localized high-pressure or low-pressure zones within the mounting cavity 130 and balancing the air pressure within the cavity. Furthermore, the momentum of the airflow entering the mounting cavity 130 from the multiple air inlets 150 cancels each other out, allowing the air pressure within the cavity 130 to quickly reach uniformity. This achieves the "rectification-pressure equalization" function within a very short path, reducing turbulent noise and mechanical vibration generated when airflow enters the mounting cavity 130, improving the quietness of the aerosol generation device, and reducing the noise generated when the aerosol generation device is being drawn in.

[0045] Please refer to Figure 2 In some embodiments, there are two air inlets 150, which are arranged 180° apart around the central axis of the atomizing channel 210.

[0046] In other embodiments, the number of air inlets 150 can be M (M is greater than 2), and the M air inlets 150 are arranged at second angle intervals around the coaxial line of the atomizing channel 210, where the second angle = 360° / M.

[0047] Please refer to Figure 2 In some embodiments, the housing assembly 100 includes a liquid storage tank 160 and a base 170. The liquid storage tank 160 has a liquid storage cavity 110 and a connection hole 163 communicating with the liquid storage cavity 110, and the atomizing assembly 200 is inserted into the connection hole 163. The base 170 is connected to the liquid storage tank 160, with a portion of the base 170 opposite to and spaced apart from the connection hole 163, and the base 170 and the liquid storage tank 160 enclose a buffer cavity 120 communicating with the connection hole 163, and the base 170 and the liquid storage tank 160 enclose a mounting cavity 130, and the first air passage 140 and the air inlet 150 are both constructed on the base 170. In the above embodiment, the liquid storage chamber 110 is connected to the buffer chamber 120 through the insertion hole 163, and the atomizing channel 210 in the atomizing assembly 200 is connected to the buffer chamber 120 through the insertion hole 163. When the aerosol generating device is drawn in, the airflow direction is: air inlet 150 → mounting chamber 130 → first air outlet 140 → buffer chamber 120 → insertion hole 163 → atomizing channel 210. In the above embodiment, the base 170 is used to support the control component 300, that is, the control component 300 is fixed on the base 170 so as to facilitate the electrical connection between the control component 300 and the atomizing component 200.

[0048] In some embodiments, the base 170 and the liquid storage tank 160 are detachably connected, that is, the base 170 and the liquid storage tank 160 are connected by detachable connection methods such as snap-fit ​​connection, magnetic connection, threaded connection, and plug-in connection. The housing assembly 100 is composed of the base 170 and the liquid storage tank 160 detachably assembled, which can reduce the assembly cost and maintenance cost of the aerosol generating device, thereby reducing the cost of the aerosol generating device. Please refer to Figure 2 and Figure 3 In some embodiments, the liquid storage chamber 160 includes a cup body 161 and a seal 162. The cup body 161 includes an integrally formed cup lid 161-1 and a side plate 161-2, and the side plate 161-2 and the cup lid 161-1 together form an installation cylinder 161-3. The seal 162 is housed in the installation cylinder 161-3, and the cup lid 161-1, the side plate 161-2, and the seal 162 together form a liquid storage cavity 110, with a insertion hole 163 formed on the seal 162. A base 170 is connected to the side plate 161-2 and covers the opening of the installation cylinder 161-3 opposite to the cup lid 161-1. A portion of the base 170 is spaced apart from the seal 162. The base 170, the seal 162, and the side plate 161-2 together form a buffer cavity 120, and the base 170 and the side plate 161-2 together form an installation cavity 130. In the above embodiment, the cup lid 161-1 and the side plate 161-2 are integrally formed, which can reduce the assembly cost of the housing assembly 100.

[0049] Please refer to Figure 2 and Figure 3 In the above embodiment, the sealing element 162 is inserted into the mounting cylinder 161-3 through the opening opposite to the cup lid 161-1, and the base 170 is inserted into the mounting cylinder 161-3 through the opening opposite to the cup cylinder, so that the cup lid 161-1, the side plate 161-2 and the sealing element 162 form a liquid storage cavity 110, the base 170, the sealing element 162 and the side plate 161-2 form a buffer cavity 120, and the base 170 and the side plate 161-2 form a mounting cavity 130. Only the cup body 161, the seal 162, and the base 170 are needed to form the mounting cavity 130, the buffer cavity 120, and the liquid storage cavity 110. This eliminates the need for the oil cup in conventional designs (i.e., the oil cup and the outer shell are integrated in this embodiment) and the bracket in conventional designs (i.e., the bracket and the bottom cover are integrated in this embodiment), thereby reducing the number of parts in the aerosol generating device and lowering material and assembly costs. In the above embodiments, when assembling the aerosol generating device, the atomizing component 200 is first inserted into the insertion hole 163, and then the atomizing component 200 and the sealing component 162 are inserted into the mounting cylinder 161-3. This simplifies the assembly steps of the aerosol generating device, reduces the assembly time of the aerosol generating device, and lowers the assembly difficulty of the aerosol generating device.

[0050] In the above embodiment, the sealing member 162 abuts against the inner wall of the side plate 161-2 to improve the airtightness of the liquid storage chamber 110. Optionally, the seal 162 can be made of silicone, rubber, or other materials that provide a certain degree of support and elasticity. This ensures that the seal 162 has sufficient support while also meeting the sealing requirements of the liquid storage chamber 110. It is understood that the base 170 is detachably connected to the liquid storage tank 160, that is, the base 170 is detachably connected to the side plate 161-2, and the side plate 161-2 is provided with a first connecting structure 164. The base 170 is provided with a second connecting structure 171 corresponding to the first connecting structure 164. The first connecting structure 164 and the second connecting structure 171 cooperate to allow the base 170 to be detachably connected to the side plate 161-2. This can reduce the assembly cost and maintenance cost of the aerosol generating device, thereby reducing the overall cost of the aerosol generating device. Optionally, the base 170 and the side plate 161-2 can be detachably connected by a threaded connection. That is, the first connecting structure 164 is an internal thread and the second connecting structure 171 is an external thread. The internal and external threads mesh, allowing the base 170 and the side plate 161-2 to be detachably connected. Optionally, the base 170 and the side plate 161-2 can be detachably connected by a snap-fit ​​connection. That is, one of the first connecting structure 164 and the second connecting structure 171 is a slot, and the other of the first connecting structure 164 and the second connecting structure 171 is a plate. The plate is engaged in the slot, so that the base 170 and the side plate 161-2 can be detachably connected. Optionally, the base 170 and the side plate 161-2 can be detachably connected by magnetic attraction. That is, one of the first connecting structure 164 and the second connecting structure 171 is a magnet, and the other of the first connecting structure 164 and the second connecting structure 171 is a magnet or a ferromagnetic structural component. The first connecting structure 164 and the second connecting structure 171 are magnetically attracted, so that the base 170 and the side plate 161-2 can be detachably connected.

[0051] Please refer to Figure 4 and Figure 5In some embodiments, the base 170 includes a base plate 172, a connecting plate 173, and a top plate 174. The top plate 174 and the base plate 172 are respectively connected to opposite ends of the connecting plate 173. At least a portion of the top plate 174 is spaced apart from the seal 162, and the top plate 174, the seal 162, and the side plates 161-2 enclose a buffer cavity 120. A first vent 140 is formed on the top plate 174, the base plate 172 covers the opening of the mounting cylinder 161-3 opposite to the cup lid 161-1, an air inlet 150 is formed on the base plate 172, and the connecting plate 173 is connected to the side plates 161-2. In the above embodiment, the second connection structure 171 is disposed on the connection plate 173.

[0052] In the above embodiments, the control component 300 is connected to at least one of the base plate 172, the connecting plate 173, and the top plate 174. Please refer to Figure 4 and Figure 5 In some embodiments, at least part of the control components 300 are disposed between the top plate 174 and the bottom plate 172. The base 170 also includes a limiting plate 175 extending from the top plate 174 toward the bottom plate 172. In the direction toward the bottom plate 172, the limiting plate 175 protrudes from the first vent hole 140. In the above embodiment, the limiting plate 175 can block the control component 300 to prevent the control component 300 from blocking the first air passage 140, thus ensuring smooth airflow.

[0053] Please refer to Figures 4 to 6 In some embodiments, the seal 162 is provided with a first snap-fit ​​structure 165, and the base 170 is provided with a second snap-fit ​​structure 176 adapted to the first snap-fit ​​structure 165. The first snap-fit ​​structure 165 and the second snap-fit ​​structure 176 snap-fit ​​each other to define the relative positions of the seal 162 and the base 170 in the distribution direction of the liquid storage cavity 110 and the mounting cavity 130.

[0054] In the above embodiment, when assembling the aerosol generating device, the base 170 and the sealing element 162 are connected first, and then the atomizing component 200 is inserted into the insertion hole 163. After that, the atomizing component 200, the sealing element 162 and the base 170 are inserted into the mounting cylinder 161-3. This simplifies the assembly steps of the aerosol generating device, reduces the assembly time of the aerosol generating device, and lowers the assembly difficulty of the aerosol generating device.

[0055] Please refer to Figure 5 and Figure 6In some embodiments, the first snap-fit ​​structure 165 includes a first snap-fit ​​groove 165-1 and a limiting portion 165-2 formed on the seal 162. The limiting portion 165-2 is connected to the side wall of the first snap-fit ​​groove 165-1 and covers a portion of the opening of the first snap-fit ​​groove 165-1. The second snap-fit ​​structure 176 includes a second snap-fit ​​groove formed on the base 170. A portion of the base 170 is received in the first snap-fit ​​groove 165-1, and the limiting portion 165-2 is received in the second snap-fit ​​groove to define the relative positions of the seal 162 and the partition in the distribution direction of the base plate 172 and the partition.

[0056] Please refer to Figure 2 In some embodiments, the housing assembly 100 further includes a liquid-absorbing member 180, which has a second vent 181. The liquid-absorbing member 180 is housed in the buffer cavity 120, and the second vent 181 is opposite to and communicates with the first vent 140. The liquid-absorbing member 180 and the sealing member 162 are spaced apart. Understandably, when a large amount of aerosol generating matrix enters the atomizing component 200, the aerosol generating matrix can easily flow out of the atomizing channel 210 and into the buffer chamber 120, causing leakage of the aerosol generating device. By providing a liquid suction element 180 in the buffer chamber 120, the aerosol generating matrix flowing into the buffer chamber 120 can be locked within the liquid suction element 180, preventing the aerosol generating matrix from flowing out of the first air passage 140, thereby preventing leakage of the aerosol generating device. In the above embodiment, when the aerosol generating device is drawn in, the airflow direction is: air inlet 150 → mounting cavity 130 → first air outlet 140 → second air outlet 181 → buffer cavity 120 → insertion hole 163 → atomization channel 210.
