Description

Technical Field

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

[0002] An aerosol generating device is a device used to heat an aerosol generating matrix, causing the matrix to atomize and form an aerosol. The aerosol formed from this atomized matrix can then be inhaled by a user.

[0003] The atomizer, as the atomizing module of an aerosol generating device, has an air inlet, an atomizing chamber, and an air outlet. The atomizing chamber connects the air inlet and the air outlet, and contains an atomizing core. During operation, the user inhales through the atomizer, and the airflow from the external environment passes sequentially through the air inlet, atomizing chamber, and air outlet under the user's inhalation. The atomizing core heats the aerosol generating substrate, causing it to atomize within the atomizing chamber to form an aerosol. The aerosol flows with the airflow within the atomizing chamber and is exhaled through the air outlet for inhalation.

[0004] In some cases, the airflow direction inside the air inlet differs from that inside the atomizing chamber, creating a large cavity between them. When the user draws air in, the airflow within this cavity becomes rapid, easily generating a large vortex that produces significant noise such as airflow noise and whistling sounds, negatively impacting the user experience.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0033] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments: Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 This is a perspective structural diagram of an aerosol generating apparatus provided in some embodiments of this application. Figure 2 for Figure 1 Cross-sectional view along AA. The atomizer provided in this application embodiment can be applied in an aerosol generating device.

[0034] Specifically, the aerosol generating device may include an atomizer and a power supply component, the power supply component being disposed on the atomizer and electrically connected to it. Understandably, the power supply component is used to supply power to the atomizer, enabling the atomizer to start and heat and atomize the aerosol generating matrix to form an aerosol.

[0035] In some possible designs, the power supply component can be located inside the atomizer.

[0036] Please refer to the following: Figures 1 to 3 ,in, Figure 3 for Figure 2 Enlarged view at point B. The atomizer provided in this embodiment includes a housing assembly 10, an atomizing core, and a filling structure 20. The housing assembly 10 has an air inlet 101, a cavity 102, an atomizing chamber 103, and an air outlet channel 104 connected in sequence. The air inlet 101 and the cavity 102 are connected along a first direction Y, and the cavity 102 and the atomizing chamber 103 are connected along a second direction X. The first direction Y and the second direction X intersect. The atomizing core is disposed in the atomizing chamber 103. The filling structure 20 is disposed in the cavity 102, and the filling structure 20 is spaced apart from the air inlet 101.

[0037] Atomizing core refers to a structure used to heat the aerosol generating matrix, causing it to atomize and form an aerosol. Atomizing chamber 103 refers to the space within the housing assembly 10 used to mount the atomizing core and to generate aerosols. Understandably, the atomizing core heats the aerosol generating matrix, causing it to atomize within the atomizing chamber 103 to form an aerosol.

[0038] The power supply component is electrically connected to the atomizer, specifically it may be electrically connected to the atomizer core.

[0039] The power supply component is located on the atomizer, specifically on the housing assembly 10. In some possible designs, the power supply component is located inside the housing assembly 10.

[0040] The air inlet 101 can be exposed to the external environment, allowing airflow from the external environment to enter the housing assembly 10 through the air inlet 101, and then sequentially pass through the cavity 102, the atomizing chamber 103, and the air outlet 104. Alternatively, the air inlet 101 can also be located inside the housing assembly 10, allowing airflow from the external environment to enter the housing assembly 10 through holes in the housing assembly 10 or assembly gaps between the components of the housing assembly 10, and then sequentially pass through the air inlet 101, the cavity 102, the atomizing chamber 103, and the air outlet 104.

[0041] The air inlet 101, cavity 102, atomizing chamber 103 and air outlet 104 are connected in sequence, so that the airflow can pass through the air inlet 101, cavity 102, atomizing chamber 103 and air outlet 104 in sequence, thereby allowing the aerosol formed in the atomizing chamber 103 to pass through the air outlet 104 with the airflow.

[0042] The air inlet 101 and the cavity 102 are connected along the first direction Y, meaning that the portion of the cavity 102 used to connect to the air inlet 101 is distributed along the first direction Y with the air inlet 101. In other words, the main portion of the cavity 102 and the air inlet 101 are distributed along the first direction Y. Based on this, airflow mainly flows from the air inlet 101 to the cavity 102 along the first direction Y. It is understood that it is permissible for a portion of the cavity 102 to be arranged with the air inlet 101 in directions other than the first direction Y; for example, a portion of the cavity 102 may surround the outer periphery of the air inlet 101.

[0043] The cavity 102 and the atomizing cavity 103 are connected along the second direction X, meaning that the portion of the cavity 102 used to connect to the atomizing cavity 103 is distributed along the second direction X with the atomizing cavity 103. In other words, the main portion of the cavity 102 and the atomizing cavity 103 are distributed along the second direction X. Based on this, the airflow mainly flows from the cavity 102 to the atomizing cavity 103 along the second direction X. Understandably, it is permissible for a portion of the cavity 102 and the atomizing cavity 103 to be arranged in directions other than the second direction X.

[0044] The intersection of the first direction Y and the second direction X means that the first direction Y and the second direction X can form an angle greater than 0° and less than 180°, that is, the first direction Y and the second direction X are not parallel. The first direction Y and the second direction X can be perpendicular to each other or not perpendicular. The first direction Y and the second direction X can be intersecting directions on the same plane, or they can be directions on planes that are skew to each other, and the projection of the second direction X onto the plane containing the first direction Y can intersect the first direction Y. As an example, the first direction Y and the second direction X are perpendicular. In some cases, the first direction Y can be the height direction of the aerosol generating device, and the second direction X can be the thickness direction or the width direction of the aerosol generating device.

[0045] Understandably, the intersection of the first direction Y and the second direction X causes the airflow direction from the air inlet 101 to the cavity 102 to differ from the airflow direction from the cavity 102 to the atomizing chamber 103. That is, as the airflow passes through the air inlet 101, the cavity 102, and the atomizing chamber 103 sequentially, it undergoes a bend within the cavity 102. This results in a more rapid airflow within the cavity 102, making it easier for an air cyclone to form within the cavity 102.

[0046] The filling structure 20 refers to the structure used to fill the cavity 102.

[0047] The filling structure 20 is spaced apart from the air inlet 101, allowing airflow to enter the space between the filling structure 20 and the air inlet 101 in the cavity 102, and then flow into the atomizing chamber 103. Understandably, at least a portion of the filling structure 20 and the air inlet 101 are spaced apart along a first direction Y.

[0048] The atomizer provided in this embodiment has a filling structure 20 disposed within the cavity 102, and the filling structure 20 is spaced apart from the air inlet 101, allowing airflow to pass sequentially through the air inlet 101, the cavity 102, the atomizing chamber 103, and the air outlet 104. Furthermore, the filling structure 20 reduces the volume of the cavity 102, which helps to reduce the air cyclone generated within the cavity 102, thereby reducing noise such as airflow noise and whistling sounds.

[0049] In some embodiments, please refer to the following: Figure 2 and Figure 3 The atomizing chamber 103 and the air outlet channel 104 are distributed along the second direction X, which facilitates the flow of air between the atomizing chamber 103 and the air outlet channel 104.

[0050] In some embodiments, please refer to the following: Figure 2 and Figure 3 The housing assembly 10 also includes a liquid storage chamber 120 for storing the aerosol generation matrix. The liquid storage chamber 120 is connected to the atomization chamber 103. Thus, the aerosol generation matrix in the liquid storage chamber 120 can flow into the atomization chamber 103 and onto the atomizing core within the atomization chamber 103. The atomizing core can then heat the aerosol generation matrix to atomize it and form an aerosol.

[0051] As an example, the liquid storage chamber 120 and the atomizing chamber 103 are distributed along the first direction Y.

[0052] In some embodiments, please refer to the following: Figure 2 and Figure 3 The housing assembly 10 may also be provided with a suction channel 130, which may be exposed outside the atomizer and is connected to the air outlet channel 104. In this way, when the user inhales from the atomizer, the aerosol can pass through the air outlet channel 104 and the suction channel 130 in sequence with the airflow for the user to inhale.

[0053] In some embodiments, the filling structure 20 is a noise reduction structure.

[0054] In this way, as the airflow enters the cavity 102 through the air inlet 101, it will impact the filling structure 20, and the noise reduction effect will be achieved under the noise reduction effect of the filling structure 20.

[0055] In some possible designs, the filling structure 20 is an elastic structure, giving it cushioning properties, which in turn allows it to achieve noise reduction. For example, the filling structure 20 can be a cushioning silicone pad.

[0056] In this way, when the airflow enters the cavity 102 through the air inlet 101 and impacts the filling structure 20, the filling structure 20 can deform under the impact of the airflow to buffer the airflow, thereby reducing the amount of vibration of the airflow in the cavity 102, which helps to reduce the noise caused by the airflow in the cavity 102.

[0057] In some embodiments, the filling structure 20 is a liquid-absorbing structure.

[0058] Understandably, the filling structure 20 has liquid absorption properties. Specifically, the filling structure 20 can absorb aerosols to generate a matrix.

[0059] This configuration allows the aerosol generation matrix in the atomization chamber 103 to be absorbed and stored by the filling structure 20 when it overflows into the cavity 102. This improves the problem of the aerosol generation matrix overflowing outside the atomizer or onto the power supply component of the atomizer.

[0060] In some embodiments, the filling structure 20 includes at least one of a cotton structure, a silicone structure, and a plastic structure.

[0061] Among them, cotton structure refers to a structure with buffering and liquid absorption properties. It can be used to buffer airflow to achieve noise reduction, and can also be used to absorb and store aerosols to form a matrix.

[0062] Among them, silicone structure refers to a structure with buffering properties, which can be used to buffer airflow, thereby achieving noise reduction effect.

[0063] The plastic structure can be, but is not limited to, ethylene-vinyl acetate copolymer, and has properties such as liquid absorption and noise reduction.

[0064] By adopting the above technical solution, the filling structure 20 can be made of a variety of materials.

[0065] In some embodiments, please refer to the following: Figures 2 to 5 ,in, Figure 4 This is a perspective structural view of the housing 1 of the atomizer provided in some embodiments of this application. Figure 5 This is a perspective view of the sealing structure 2 of the atomizer provided in some embodiments of this application. The housing assembly 10 includes a housing 1 and a sealing structure 2. The housing 1 has an atomizing chamber 103 and an air outlet channel 104. The sealing structure 2 is located at one end of the housing 1 along the first direction Y to seal the atomizing chamber 103 and the air outlet channel 104. The sealing structure 2 has an air inlet 101, and the sealing structure 2 and the housing 1 form a cavity 102. The filling structure 20 abuts against the housing 1 and the sealing structure 2 along the first direction Y.

[0066] The sealing structure 2 is located at one end of the housing 1 along the first direction Y, meaning that the sealing structure 2 is located at one end of the housing 1 along the first direction Y, wherein at least a portion of the sealing structure 2 may be located inside one end of the housing 1 along the first direction Y.

[0067] The sealing structure 2 seals the atomizing chamber 103 and the air outlet channel 104, so that the airflow can strictly pass through the air inlet 101, air, atomizing chamber 103 and air outlet channel 104 in sequence, and leakage through the atomizing chamber 103 and air outlet channel 104 is minimized.

[0068] The filling structure 20 abuts against the housing 1 and the sealing structure 2 along the first direction Y, so that the filling structure 20 can be stably assembled inside the housing assembly 10. In this way, during the assembly of the atomizer, the filling structure 20 can be placed at one end of the housing 1 along the first direction Y, and then the sealing structure 2 can be placed at the other end of the housing 1 along the first direction Y. In this way, the filling structure 20 abuts against the housing 1 and the sealing structure 2 along the first direction Y, realizing the assembly of the filling structure 20, making the assembly operation of the filling structure 20 very simple and convenient.

[0069] In some possible designs, the filling structure 20 and the air inlet 101 are spaced apart along the first direction Y.

[0070] In some possible designs, the air inlet 101 passes through the sealing structure 2 along the first direction Y.

[0071] In some embodiments, please refer to Figure 2 The liquid storage chamber 120 is located inside the shell 1.

[0072] In some embodiments, please refer to the following: Figure 1 and Figure 2 The housing assembly 10 may also include a nozzle 3, which is disposed at the end of the housing 1 away from the sealing structure 2 along the first direction Y. The nozzle 3 is provided with a suction channel 130. In this way, the user can inhale through the nozzle 3, so that the aerosol passes through the atomizing chamber 103, the air outlet channel 104 and the suction channel 130 in sequence with the airflow for the user to inhale.

[0073] In some embodiments, please refer to the following: Figures 2 to 5 And in conjunction with other accompanying drawings. The sealing structure 2 includes a sealing body 21 and a first enclosure portion 22. The sealing body 21 is located at one end of the housing 1 along the first direction Y to seal the atomizing chamber 103 and the air outlet channel 104. The sealing body 21 is provided with an air inlet 101. The first enclosure portion 22 is located at one end of the sealing body 21 along the first direction Y near the housing 1, and the first enclosure portion 22 surrounds the outer periphery of the air inlet 101. The housing 1, the sealing body 21 and the first enclosure portion 22 enclose to form a cavity 102. The filling structure 20 abuts against the first enclosure portion 22 and the housing 1 along the first direction Y. The first enclosure portion 22 is provided with a first notch 108 at one end along the second direction X, and the first notch 108 connects the atomizing chamber 103 and the cavity 102.

[0074] The sealing body 21 is the main part of the sealing structure 2. As an example, the sealing body 21 has an air inlet 101 extending through it in the first direction Y.

[0075] The first enclosure part 22 refers to the component used to assist in forming the cavity 102 and for assembling the filling structure 20.

[0076] Understandably, the first enclosure portion 22 extends beyond the air inlet 101 along the first direction Y away from the sealing body 21. Thus, the filling structure 20 abuts against the first enclosure portion 22 and the housing 1 along the first direction Y, such that the filling structure 20 and the air inlet 101 are spaced apart along the first direction Y.

[0077] By setting the first enclosure 22, it is convenient to construct the cavity 102 on the one hand, and to assemble the filling structure 20 on the other hand.

[0078] Understandably, airflow can flow from cavity 102 to atomizing cavity 103 through the first notch 108.

[0079] In some embodiments, please refer to the following: Figures 2 to 5 In conjunction with other accompanying drawings, the sealing structure 2 also includes a protrusion 23, which is located at one end of the sealing body 21 along the first direction Y near the housing 1. The protrusion 23 is located in the cavity 102, and the air inlet 101 is located on the protrusion 23.

[0080] Understandably, the air inlet 101 passes through the sealing body 21 and the protrusion 23.

[0081] Understandably, the first enclosure portion 22 is spaced around the protrusion 23, and the first enclosure portion 22 and the protrusion 23 are spaced apart. In this way, a portion of the cavity 102 can be formed between the outer periphery of the protrusion 23 and the first enclosure portion 22.

[0082] Understandably, the first enclosure portion 22 extends beyond the protrusion 23 in the first direction Y, away from the sealing body 21. This ensures that when the filling structure 20 abuts against the first enclosure portion 22 and the housing 1 in the first direction Y, the filling structure 20 and the protrusion 23 are spaced apart in the first direction Y, thereby ensuring that the filling structure 20 and the air inlet 101 are spaced apart in the first direction Y.

[0083] By providing the protrusion 23, when the aerosol generating matrix in the atomization chamber 103 leaks into the cavity 102, the space between the outer periphery of the protrusion 23 and the first enclosure 22 can be used to store the aerosol generating matrix, thereby reducing the risk of the aerosol generating matrix leaking through the air inlet 101.

[0084] In some embodiments, please refer to the following: Figures 2 to 5 Furthermore, in conjunction with other accompanying drawings, the outer peripheral wall of the protrusion 23 is tapered in the direction from the first direction Y toward the filling structure 20.

[0085] The protrusion 23 may be, but is not limited to, a frustum-shaped structure, a pyramid-shaped structure, a cone-shaped structure, or a pyramidal structure.

[0086] In this way, if the aerosol generation matrix accidentally leaks onto the protrusion 23, the aerosol generation matrix can slide down along the outer peripheral wall of the protrusion 23 toward the sealing body 21, thereby reducing the risk of the aerosol generation matrix leaking into the air inlet 101.

[0087] In some embodiments, please refer to the following: Figures 2 to 5 And in conjunction with other accompanying drawings. The housing 1 has a second enclosure portion 11 at one end near the sealing structure 2 in the first direction Y. The second enclosure portion 11 encloses and forms an atomizing chamber 103, and abuts against the sealing body 21 along the first direction Y. The second enclosure portion 11 has a second notch 109 and a third notch 110. The second notch 109 connects the atomizing chamber 103 and the first notch 108, and the third notch 110 connects the atomizing chamber 103 and the air outlet channel 104.

[0088] The second enclosure 11 is a part of the shell 1.

[0089] The second enclosure portion 11 abuts against the sealing body 21 along the first direction Y, so that the sealing body 21 can achieve a sealing effect on the atomizing cavity 103 formed by the second enclosure portion 11.

[0090] The second notch 109 connects the atomizing chamber 103 and the first notch 108, allowing the airflow in the cavity 102 to flow sequentially through the first notch 108 and the second notch 109 into the atomizing chamber 103. That is, the first notch 108 and the second notch 109 connect the cavity 102 and the atomizing chamber 103. As an example, the first enclosure 22 and the second enclosure 11 can abut against each other along the second direction X.

[0091] The third notch 110 connects the atomizing chamber 103 and the air outlet channel 104, allowing the airflow and aerosol in the atomizing chamber 103 to flow into the air outlet channel 104 through the third notch 110. That is, the third notch 110 connects the atomizing chamber 103 and the air outlet channel 104.

[0092] As an example, the atomizing chamber 103 and the air outlet channel 104 are arranged along the second direction X, and the second notch 109 and the third notch 110 are respectively arranged at both ends of the second enclosure portion 11 along the second direction X.

[0093] This configuration allows the cavity 102, the atomizing chamber 103, and the air outlet channel 104 to be connected sequentially.

[0094] In some embodiments, please refer to the following: Figures 2 to 5 In conjunction with other accompanying drawings, at least a portion of the sealing structure 2 is disposed within the housing 1, and the outer peripheral wall of the sealing structure 2 is engaged with the inner peripheral wall of the housing 1.

[0095] Understandably, the inner peripheral wall of the housing 1 is provided with a first fastening position 12, and the outer peripheral wall of the sealing structure 2 is provided with a second fastening position 24. The first fastening position 12 and the second fastening position 24 are fastened to each other, so that the sealing structure 2 can be stably assembled into one end of the housing 1 along the first direction Y.

[0096] Among them, the first snap position 12 can be a snap groove, and the second snap position 24 is a snap fastener, such as... Figure 4 and Figure 5 As shown. Alternatively, the first snap position 12 is a snap fastener, and the second snap position 24 is a snap groove.

[0097] This arrangement facilitates the assembly between the sealing structure 2 and the housing 1, thereby facilitating the assembly of the filling structure 20.

[0098] In some embodiments, please refer to the following: Figures 2 to 5 And in conjunction with other accompanying drawings. The housing 1 has a first negative pressure channel 105, which is sealed by a sealing structure 2. The sealing structure 2 has a second negative pressure channel 106. At one end of the sealing structure 2 away from the housing 1 along the first direction Y, there is a mounting cavity 107, which connects to the second negative pressure channel 106. A pressure sensor is installed within the mounting cavity 107, and the pressure sensor is sealed within the second negative pressure channel 106. An air inlet 101 penetrates the end of the sealing structure 2 away from the housing 1 along the first direction Y, connecting the first negative pressure channel 105 and the second negative pressure channel 106.

[0099] Understandably, the second negative pressure channel 106 and the mounting cavity 107 together penetrate the sealing structure 2 along the first direction Y.

[0100] Among them, the barometric pressure sensor can be, but is not limited to, a microphone.

[0101] An air inlet 101 penetrates the end of the sealing structure 2 away from the housing 1 along the first direction Y, thus exposing the air inlet 101 to the end of the sealing structure 2 away from the housing 1 along the first direction Y. A mounting cavity 107 is provided at the end of the sealing structure 2 away from the housing 1 along the first direction Y, thus exposing the mounting cavity 107 to the end of the sealing structure 2 away from the housing 1 along the first direction Y. That is, the air inlet 101 and the mounting cavity 107 are exposed at the end of the sealing structure 2 away from the housing 1 along the first direction Y, causing the air pressure in the mounting cavity 107 and the air inlet 101 to be similar.

[0102] By adopting the above technical solution, when the user inhales, the airflow can pass through the air inlet 101, cavity 102, atomizing chamber 103 and air outlet 104 in sequence. Based on the similarity of air pressure between the mounting chamber 107 and the air inlet 101, the first negative pressure channel 105 and the second negative pressure channel 106 can approach a negative pressure state, thereby creating a large air pressure difference on both sides of the air pressure sensor. This allows the air pressure sensor to activate the atomizing core, so that the atomizing core heats the aerosol generation matrix.

[0103] The power supply component is electrically connected to the atomizer, and may also include an electrical connection between the power supply component and the air pressure sensor. When the user inhales, creating a significant pressure difference across the air pressure sensor, the sensor activates. The power supply component then powers the atomizer core based on the signal from the air pressure sensor, allowing the atomizer core to heat the aerosol-generating matrix.

[0104] In some embodiments, please refer to the following: Figures 1 to 3 The suction channel 130 and the first negative pressure channel 105 are connected. Based on this, during the user's suction process, the airflow in the first negative pressure channel 105 and the second negative pressure channel 106 can be suctioned, which helps to increase the air pressure difference on both sides of the air pressure sensor, making it easier to achieve the effect of suction to start the atomizing core.

[0105] In some embodiments, please refer to the following: Figures 2 to 5 And in conjunction with other accompanying drawings. In the first direction Y, at least a portion of the diameter of the air inlet 101 is gradually reduced toward the cavity 102.

[0106] That is, in the direction from the air inlet 101 to the cavity 102 along the first direction Y, the diameter of at least a portion of the air inlet 101 gradually decreases. As an example, such as... Figure 2 and Figure 3 As shown, the diameter of the air inlet 101 gradually decreases in the direction from the first direction Y to the cavity 102.

[0107] The inner peripheral wall of the air inlet 101 can be in the shape of a frustum or a pyramid.

[0108] This design allows for control of the airflow resistance within the air inlet 101, i.e., by increasing the airflow resistance within the air inlet 101. This ensures a larger pressure difference across the air pressure sensor during inhalation, facilitating the activation of the atomizing core during inhalation.

[0109] Please refer to the following: Figure 1 and Figure 2The aerosol generating device provided in this embodiment includes an atomizer and a power supply component. The power supply component is disposed on the atomizer and electrically connected to the atomizer. The atomizer in this embodiment is the same as the atomizer in the previous embodiments; please refer to the relevant descriptions of the atomizers in the previous embodiments for details, which will not be repeated here.

[0110] Specifically, the power supply component is located inside the housing assembly 10 of the atomizer and is electrically connected to the atomizer core and the pressure sensor.

[0111] The aerosol generating device provided in this application, by employing the atomizers involved in the above embodiments, can reduce noise such as airflow noise and whistling generated during the use of the aerosol generating device.

The circuit board assembly 40 is electrically connected to the battery 30, the air pressure sensor is electrically connected to the circuit board assembly 40, and the circuit board assembly 40 is electrically connected to the atomizer core.

[0113] Specifically, the circuit board assembly 40 is used to receive signals from the air pressure sensor and to control the battery 30 to supply power to the atomizing core.
