[0045] This application provides an atomizer 10, see the following embodiment. Figures 3 to 5 The atomizer 10 includes an atomizing chamber 10a, an air outlet channel 10b, and an air inlet 10c.

[0046] The generated aerosol can enter the atomization chamber 10a.

[0047] The air outlet channel 10b connects the atomizing chamber 10a and the outside of the atomizer 10, and is located downstream of the atomizing chamber 10a along the airflow direction. The air outlet channel 10b includes a constriction section 10ba, and at least part of the cross-sectional area of ​​the constriction section 10ba gradually decreases along the airflow direction.

[0048] The air inlet 10c connects the air outlet channel 10b to the outside of the atomizer 10, and the connection between the air inlet 10c and the air outlet channel 10b forms a connection port.

[0049] The connection port is located on the wall of the contraction section 10ba, or the connection port is located on the wall of the outlet passage 10b in the downstream part of the contraction section 10ba along the airflow direction.

[0050] The aerosol generating matrix within the atomizer 10 is atomized by an atomizing component. The atomized aerosol generating matrix then mixes with air within the atomizer 10 cavity to form an aerosol. The atomizing component can be any one or any combination of an electric heating element, an electromagnetic sensor element, a light wave heater, or an ultrasonic device. The aerosol generating matrix is ​​a matrix capable of releasing volatile compounds that can form aerosols, and can be in solid, liquid, or paste form.

[0051] Understandably, during the use of the atomizer 10, the air outlet channel 10b can create negative pressure through the user's inhalation. Under the action of negative pressure, the aerosol enters from the atomizing chamber 10a into the air outlet channel 10b and flows out of the air outlet channel 10b before entering the user's body.

[0052] The contraction section 10ba is part of the exhaust passage 10b.

[0053] The cross section of the contraction section 10ba refers to the contour formed by the wall boundary of the contraction section 10ba taken at any position of the contraction section 10ba perpendicular to the direction of airflow.

[0054] Along the direction of airflow, at least part of the cross-sectional area of ​​the contraction section 10ba gradually decreases. Thus, as the airflow flows through the contraction section 10ba, the airflow velocity continuously increases.

[0055] By increasing the airflow velocity, the force exerted by the airflow on the droplet particles of the aerosol generation matrix carried in the airflow is increased, which helps to further break down and decompose the droplet particles of the aerosol generation matrix into smaller droplet particles under the force.

[0056] Due to the airflow, the air pressure in the air outlet channel 10b decreases, allowing air from outside the atomizer 10 to enter the air outlet channel 10b through the air inlet 10c.

[0057] The airflow in the air inlet 10c enters the air outlet 10b. On the one hand, it can impact the droplet particles of the aerosol generating matrix, which helps to further break down and decompose the droplet particles of the aerosol generating matrix into smaller droplet particles under the force, reducing the phenomenon of droplet particles of the aerosol generating matrix agglomerating. On the other hand, it can dilute the content of the aerosol generating matrix in the airflow.

[0058] The atomizer 10 in this embodiment, by increasing the airflow velocity and introducing additional airflow into the outlet channel 10b through the air inlet 10c, helps to make the droplet particles of the aerosol generation matrix smaller and mix more evenly with the airflow, resulting in a more delicate and mellow taste of the aerosol; it also helps to reduce the visual effect of the smoke formed after the aerosol flows out of the atomizer 10, thus reducing the adverse impact on the surrounding environment caused by user use; it eliminates the need for an additional power source to accelerate the airflow and allow the airflow to enter the outlet channel 10b from the air inlet 10c, simplifying the structure of the atomizer 10 and reducing energy consumption; the air supplemented through the air inlet 10c can increase the moisture content in the aerosol, resulting in a more moist taste for the user and improving the user experience.

[0059] It is understandable that when the atomizer 10 atomizes the aerosol to generate the matrix by heating, the temperature of the aerosol is relatively high. The airflow introduced through the air inlet 10c is ambient air, which helps to reduce the temperature of the aerosol flowing out from the outlet of the air outlet 10b and improves the user's vaping experience.

[0060] In some embodiments, the cross-sectional shape of each position of the contraction section 10ba is the same, which helps to improve the stability of the airflow in the contraction section 10ba.

[0061] In some embodiments, the wall of the contraction section 10ba is conical, which helps to improve the stability of the airflow in the contraction section 10ba and makes the airflow smoother.

[0062] In some embodiments, the inlet of the contraction section 10ba along the airflow direction is connected to the atomizing chamber 10a, so that the airflow can be directly accelerated after entering the outlet channel 10b.

[0063] In some embodiments, see Figure 6 The connecting port is located on the wall of the downstream portion of the contraction section 10ba.

[0064] The downstream portion of the contraction section 10ba refers to the latter half of the contraction section 10ba along the direction of airflow.

[0065] This allows for a faster flow rate of the airflow from the connecting port, which in turn helps to increase the flow rate of the airflow from the inlet 10c into the outlet channel 10b.

[0066] In some embodiments, see Figure 3 and Figure 5 The exhaust passage 10b also includes a transition section 10bb, which is located downstream of the contraction section 10ba along the airflow direction. The air inlet 10c is connected to the transition section 10bb, and the cross-sectional area of ​​the transition section 10bb is smaller than the maximum cross-sectional area of ​​the contraction section 10ba.

[0067] After the airflow exits from the contraction section 10ba, it enters the transition section 10bb, and the connecting hole is located on the wall of the transition section 10bb.

[0068] The cross-sectional area of ​​the transition section 10bb is smaller than the maximum cross-sectional area of ​​the contraction section 10ba. In other words, the airflow velocity in the transition section 10bb is greater than that before the airflow enters the contraction section 10ba.

[0069] This results in a higher airflow velocity in the transition section 10bb, which is beneficial for increasing the airflow velocity from the inlet 10c into the outlet channel 10b.

[0070] In some embodiments, see Figure 5Along the direction of airflow, the cross-sectional area of ​​the transition section 10bb shall not exceed the minimum cross-sectional area of ​​the contraction section 10ba.

[0071] In this way, on the one hand, the airflow velocity in the transition section 10bb is high, which is conducive to increasing the airflow velocity from the air inlet 10c into the air outlet channel 10b, and further decomposing the droplet particles of the aerosol generation matrix under the impact of the airflow; on the other hand, the cross-sectional area of ​​the transition section 10bb is constant, which maintains the stability of the airflow and reduces the adverse effects of airflow turbulence on the user's suction smoothness.

[0072] It is understandable that after the user finishes using the atomizer 10, aerosol droplets may remain in the air outlet channel 10b. These droplets may aggregate and form a liquid flow that exits from the air outlet channel 10b, adversely affecting the user experience. In this embodiment, on the one hand, the air inlet 10c is connected to the outside of the atomizer 10, improving the evaporation effect of the residual aerosol droplets and reducing the probability of them aggregating and forming a liquid flow. On the other hand, the interconnected transition section 10bb and converging section 10ba allow the liquid flow to converge at the transition section 10bb. During the user's use of the atomizer 10, the airflow entering the transition section 10bb from the air inlet 10c impacts the liquid flow, causing it to break up again and reducing the probability of liquid flowing out.

[0073] In some embodiments, the cross-sectional shape of each position of the transition section 10bb is the same, which helps to improve the stability of the airflow in the transition section 10bb.

[0074] In some embodiments, the wall of the transition section 10bb is cylindrical, which helps to improve the stability of the airflow in the transition section 10bb and makes the airflow smoother.

[0075] In some embodiments, see Figure 5 The transition section 10bb is connected to the contraction section 10ba. Along the flow direction of the airflow, the cross-sectional area of ​​the transition section 10bb remains unchanged, and the cross-sectional area of ​​the transition section 10bb is the same as the cross-sectional area of ​​the outlet of the contraction section 10ba.

[0076] This allows the airflow to maintain its maximum speed in the transition section 10bb after accelerating to its maximum speed in the contraction section 10ba, thus ensuring that the airflow in the transition section 10bb remains at a high velocity.

[0077] In some embodiments, the cross-sectional area of ​​the air inlet 10c does not exceed the cross-sectional area of ​​the transition section 10bb.

[0078] This helps reduce the probability of excessively low aerosol concentration due to excessive airflow entering the transition section 10bb through the air inlet 10c.

[0079] In some embodiments, the cross-sectional area of ​​the inlet of the transition section 10bb is the same as the cross-sectional area of ​​its outlet.

[0080] It is understandable that by adjusting the ratio between the cross-sectional area of ​​the air inlet 10c and the cross-sectional area of ​​the transition section 10bb, the concentration of aerosol and the size of droplets in the aerosol can be adjusted.

[0081] It is understandable that during the use of the atomizer 10, the user may come into contact with the structure that forms the outlet of the air outlet channel 10b.

[0082] In some embodiments, see Figure 2 and Figure 4 The air outlet 10b extends along the first direction, and the air inlet 10c extends along the second direction, with the first direction intersecting the second direction.

[0083] This helps reduce the probability that the user will block the air intake 10c during the use of the atomizer 10, preventing outside air from entering the air intake 10c.

[0084] The specific number of air intake vents 10c is not limited; it can be one or more.

[0085] In some embodiments, there are multiple air inlets 10c, which are spaced apart from each other and arranged around the periphery of the air outlet channel 10b.

[0086] This allows some of the air intake holes 10c to be blocked or obstructed, while outside air can still enter the exhaust channel 10b through other air intake holes 10c.

[0087] In some embodiments, the first direction is perpendicular to the second direction, which helps to reduce the length of the air inlet 10c and improve the efficiency of airflow entering the air outlet channel 10b through the air inlet 10c.

[0088] In some embodiments, the wall of the air inlet 10c is cylindrical to facilitate the manufacture of the air inlet 10c.

[0089] In some embodiments, see Figure 5 and Figure 6 The air outlet channel 10b also includes an expansion section 10bc, which is located downstream of the contraction section 10ba and communicates with the outside of the atomizer 10. The cross-sectional area of ​​the inlet of the expansion section 10bc is smaller than the cross-sectional area of ​​its outlet, and the connection port is located outside the expansion section 10bc and upstream of the expansion section 10bc.

[0090] The airflow exiting the contraction section 10ba can flow into the expansion section 10bc. The outlet of the expansion section 10bc is connected to the outside of the atomizer 10.

[0091] The cross-sectional area of ​​the inlet of expansion section 10bc is smaller than that of its outlet, which means that the airflow velocity at the outlet of expansion section 10bc is lower than that at the inlet of expansion section 10bc. In other words, the airflow velocity decreases after passing through expansion section 10bc.

[0092] This helps to reduce the flow rate of the aerosol inhaled by the user, reduce the suction resistance during the inhalation process, and improve the user experience.

[0093] It is understandable that the connection port is located outside and upstream of the expansion section 10bc, which helps to ensure that the airflow in the inlet 10c is not affected by the reduced airflow velocity in the expansion section 10bc.

[0094] In some embodiments, the cross-sectional area of ​​the expansion section 10bc remains unchanged along the flow direction of the airflow, thus simplifying the manufacturing process of the expansion section 10bc.

[0095] In some embodiments, see Figure 5 Along the direction of airflow, the cross-sectional area of ​​the expansion section 10bc gradually increases.

[0096] This helps to improve the stability of airflow within the expansion section 10bc and reduces the probability of turbulence in the airflow within the expansion section 10bc.

[0097] In some embodiments, the wall of the expansion section 10bc is conical, which helps to improve the stability of the airflow in the expansion section 10bc and makes the airflow smoother.

[0098] In some embodiments, see Figure 6 The expanding segment 10bc is connected to the contracting segment 10ba, with the connection point located in the contracting segment 10ba. In other words, the inlet of the expanding segment 10bc is the outlet of the contracting segment 10ba.

[0099] In some embodiments with a transition section 10bb, see [reference] Figure 5 Along the direction of airflow, the contraction section 10ba, the transition section 10bb, and the expansion section 10bc are connected in sequence.

[0100] This allows the aerosol, which is uniformly mixed in the transition section 10bb, to enter the expansion section 10bc at a reduced flow rate, resulting in a smoother and more delicate user experience.

[0101] In some embodiments, see Figures 1 to 3The atomizer 10 includes a housing 11 and a mounting assembly 12. The mounting assembly 12 has an atomizing chamber 10a. The housing 11 has an air outlet channel 10b that runs through the housing in a first direction. The housing 11 is located on one side of the mounting assembly 12 along the first direction and the two are sealed together in the first direction. The housing 11 includes a mouthpiece 111 and the outlet of the air outlet channel 10b is located on the outer surface of the mouthpiece 111.

[0102] The housing 11 and the mounting assembly 12 are assembled along the first direction, which enables the air outlet channel 10b to communicate with the atomizing chamber 10a and the housing 11 to be sealed with the mounting assembly 12, thus simplifying the manufacturing and assembly process of the atomizer 10.

[0103] Understandably, the atomizing chamber 10a has an opening on one side along the first direction for communicating with the air outlet channel 10b.

[0104] The mouthpiece 111 is for the user to inhale, so that the outlet of the air passage 10b is connected to the user's mouth during the use of the atomizer 10.

[0105] In some embodiments, the housing 11 is provided with an installation space that communicates with the air outlet channel 10b. The installation space is open on one side away from the air outlet channel 10b in a first direction, and at least a portion of the installation assembly 12 can be inserted into the installation space through the open position of the installation space.

[0106] Part of the wall of the installation space and the installation component 12 form a storage cavity, which is used to store the aerosol generation matrix.

[0107] In some embodiments, see Figure 3 The mounting assembly 12 includes a mounting base 122 and an atomizing core 121. The mounting base 122 has a mounting cavity, and at least a portion of the atomizing core 121 is located in the mounting cavity and together with a portion of the wall of the mounting cavity to form an atomizing cavity 10a.

[0108] The atomizing core 121 can absorb the aerosol generation matrix and atomize the aerosol generation matrix through heating, ultrasonic atomization and other methods.

[0109] A portion of the outer surface of the atomizing core 121 forms part of the wall of the atomizing chamber 10a.

[0110] In some embodiments, see Figure 4 and Figure 5 The outlet of the air outlet channel 10b is located on the end face of the nozzle portion 111 along the first direction, and the inlet of the air inlet 10c is located on the surface of the nozzle portion 111 along the second direction and is spaced apart from the outlet of the air outlet channel 10b along the first direction. The first direction and the second direction intersect.

[0111] This reduces the likelihood of the user's lips blocking the air inlet 10c during the sucking process, allowing air to freely enter the air inlet 10c.

[0112] This application also provides an aerosol generating device, see below. Figures 7 to 9 The aerosol generating device includes an atomizing component 13, an air outlet channel 10b, an air inlet 10c, and a power supply component 20.

[0113] The atomizing component 13 is used to generate aerosol, and the atomizing component 13 is provided with an atomizing chamber 10a.

[0114] The air outlet channel 10b connects the atomizing chamber 10a with the outside of the atomizer 10 and is located downstream of the atomizing assembly 13 along the airflow direction. The air outlet channel 10b includes a constriction section 10ba, and at least part of the cross-sectional area of ​​the constriction section 10ba gradually decreases along the airflow direction.

[0115] The air inlet 10c connects the air outlet channel 10b to the outside of the atomizer 10, and the connection between the air inlet 10c and the air outlet channel 10b forms a connection port.

[0116] The connection port is located on the wall of the contraction section 10ba, or the connection port is located on the wall of the outlet passage 10b in the downstream part of the contraction section 10ba along the airflow direction.

[0117] The power supply assembly 20 is electrically connected to the atomizing assembly 13.

[0118] The power supply component 20 is used to provide electrical energy to the atomizing component 13 so that the atomizing component 13 can atomize the aerosol to generate a matrix.

[0119] In some embodiments, the atomizing component 13 includes an atomizing core 121.

[0120] In some embodiments, the atomizer 10 in the foregoing embodiments includes an atomizing component 13, and the atomizer 10 is detachably connected to the power component 20 so as to be replaced after the power component 20 is damaged or the power is depleted.

[0121] The power supply assembly 20 includes electrodes and a battery. The electrodes can contact the atomizing assembly 13 to achieve an electrical connection between the two, and the electrodes can contact the battery to achieve an electrical connection between the two.

[0122] In other embodiments, the aerosol generating device is an integrated package structure, that is, the atomizing component 13 and the power supply component 20 are non-detachable, and the aerosol generating device is for single use, which helps to reduce the manufacturing cost of the aerosol generating device.
