Description

Technical Field

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

[0002] An aerosol generating device is a small device that uses heating technology to act on an aerosol generating matrix and generate aerosols. In related technologies, an aerosol generating device includes an atomizer with an air inlet chamber. The air inlet chamber allows outside air to flow to the bottom of the aerosol generating matrix, enabling the matrix to generate aerosols when heated. However, during the use of the aerosol generating device, aerosols easily condense and deposit at the bottom of the air inlet chamber, obstructing the flow of outside air and affecting the normal operation of the aerosol generating device. Therefore, how to reduce or even avoid aerosol condensation at the bottom of the air inlet chamber has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] The embodiments of this application provide an atomizer and an aerosol generating device to solve at least one of the above-mentioned technical problems.

[0004] The atomizer according to this application includes a container and an inlet gas. The container has an internal cavity for containing an aerosol generation matrix. The inlet gas is connected to the container and has an internal air intake chamber that communicates with the container cavity and allows outside air to flow into the container cavity. The inlet gas has multiple spaced-apart air inlets forming an air intake area for allowing outside air to flow into the air intake cavity. The air intake area at least partially corresponds to the periphery of the air intake cavity.

[0006] In some embodiments, when at least a portion of the air inlet corresponds to a position close to the bottom wall of the intake gas, the wall of the air inlet is tangent to the bottom wall of the intake gas.

[0007] In some embodiments, when at least a portion of the air inlet corresponds to a position communicating with the air inlet chamber near the sidewall of the air intake in the radial direction corresponding to the maximum range of the air intake direction, the wall of the air inlet is tangent to the corresponding position of the sidewall of the air intake.

[0008] In some embodiments, the central axes of the plurality of air inlets are parallel to each other.

[0009] In some embodiments, a plurality of the air intake holes are arranged in an array, with each row of air intake holes having the same number of holes in the axial direction of the air intake cavity.

[0010] In some embodiments, the array of multiple air intake holes is arranged such that, in the axial direction of the air intake cavity, the row of air intake holes closest to the bottom wall of the air intake cavity has a greater number of holes than the other rows of air intake holes.

[0011] In some embodiments, the number of the multiple rows of air inlets gradually increases in the direction from the receiving cavity to the air inlet cavity.

[0015] In the atomizer and aerosol generating device of this application embodiment, the gas inlet is provided with a plurality of spaced air inlets, which form an air inlet area for allowing outside air to flow into the air inlet chamber. The air inlet area at least partially corresponds to the periphery of the air inlet chamber, thereby reducing the airflow dead zone in the air inlet chamber, thereby reducing or even avoiding the condensation and deposition of aerosols in the air inlet chamber, preventing the flow of outside air from being blocked, and thus improving the stability and reliability of the aerosol generating device.

[0034] In related technologies, aerosol generating devices include an atomizer with an air inlet chamber. The air inlet chamber allows outside air to flow to the bottom of the aerosol generating matrix, enabling the matrix to generate aerosols when heated. However, during the use of the aerosol generating device, aerosols easily condense and deposit at the bottom of the air inlet chamber, obstructing the flow of outside air and affecting the normal operation of the device. Therefore, how to reduce or even avoid aerosol condensation at the bottom of the air inlet chamber has become a technical problem that urgently needs to be solved by those skilled in the art. For a solution to this problem, please refer to [link to relevant documentation]. Figure 1 This application provides an atomizer 10 and an aerosol generating device 100.

[0035] Please see Figure 1 and Figure 2 The aerosol generating device 100 provided in this application includes an electronic control component 30 and an atomizer 10, with the atomizer 10 electrically connected to the electronic control component 30.

[0036] It is understood that the atomizer 10 is a structure in the aerosol generating device 100 used to heat the aerosol generating matrix 300 to generate aerosols from the aerosol generating matrix 300. The aerosol generating matrix 300 is a processed product capable of generating aerosols under conditions such as heating, ultrasound, or mechanical vibration. The aerosol generating matrix 300 can be in a liquid state, or in a fully solid or semi-solid state. The aerosol can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.

[0037] In some embodiments of this application, the atomizer 10 includes a heating element 101. When the heating element 101 is energized, it can heat the aerosol generating matrix 300 to generate aerosols. The heating method of the heating element 101 to heat the aerosol generating matrix 300 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating, and laser irradiation heating. For example, the heating element 101 can be arranged around the outer side of the aerosol generating matrix 300, thus enabling the heating element 101 to heat the aerosol generating matrix 300 in a circumferential heating manner.

[0038] In some embodiments, the electronic control component 30 includes a power supply unit and a control unit. The power supply unit is electrically connected to the atomizer 10. The control unit is electrically connected to the power supply unit and is used to control the power supply unit to supply power to the atomizer 10. Specifically, when the aerosol generating device 100 is being drawn in, the control unit can control the power supply unit to output electrical energy to the atomizer 10. In this case, the atomizer 10 can heat and atomize the aerosol generating matrix 300 to generate aerosol. When the aerosol generating device 100 is not being drawn in, the control unit can control the power supply unit to stop supplying electrical energy to the atomizer 10. In this case, the atomizer 10 will not heat the aerosol generating matrix 300. It should be noted that in some embodiments, the power supply unit can be a dry cell battery or a rechargeable battery; rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0039] Furthermore, in some embodiments, the aerosol generating device 100 further includes a housing 50, within which the electronic control component 30 and the atomizer 10 are disposed. The housing 50 is a structure in the aerosol generating device 100 that can accommodate and protect the atomizer 10 and the electronic control component 30, etc. The material of the housing 50 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. In some embodiments, the housing 50 may be made of plastic, which makes the housing 50 lighter and facilitates the portability of the aerosol generating device 100. In other embodiments, the housing 50 may be made of a high-temperature resistant material, which prevents the housing 50 from being damaged by heat (e.g., deformation), ensuring the stability and reliability of the aerosol generating device 100. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK) materials, high-melting-point metals, and high-temperature resistant ceramics.

[0040] Since the aerosol generating device 100 in this embodiment includes an atomizer 10, it is understood that the aerosol generating device 100 has at least the same beneficial effects as the atomizer 10. Therefore, for the beneficial effects of the aerosol generating device 100, please refer to the beneficial effects of the atomizer 10 described below.

[0041] Please see Figure 2 and Figure 3 and combined Figure 4 or Figure 6The atomizer 10 of this application includes a container 11 and an air inlet 13. The container 11 has an internal cavity 111 for containing the aerosol generating matrix 300. The air inlet 13 is connected to the container 11 and has an internal air inlet chamber 131. The air inlet chamber 131 communicates with the container chamber 111 and is used to allow outside air to flow into the container chamber 111. The air inlet 13 has multiple spaced air inlets 1333, which form an air intake area for allowing outside air to flow into the air intake chamber 131. The air intake area at least partially corresponds to the periphery of the air intake chamber 131. The body 11 and the multiple air inlets 133 are also included. The main body 11 is provided with a receiving cavity 111 and an air inlet cavity 131. The receiving cavity 111 is used to receive the aerosol generating matrix 300. The air inlet cavity 131 is connected to the receiving cavity 111 and is used to allow outside air to flow into the receiving cavity 111. A plurality of air inlets 133 are spaced apart on the side wall 137 of the air inlet 13 and are used to allow outside air to flow into the air inlet cavity 131. At least some of the air inlets 133 correspond to positions in the air inlet cavity 131 in the axial direction X near the bottom wall 135 of the air inlet 13; and / or, at least some of the air inlets 133 correspond to positions in the air inlet cavity 131 in the radial direction Y near the side wall 137 of the air inlet 13.

[0042] It is understood that the container 11 is a structure in the atomizer 10 used to house components such as the heating element 101. The materials of the container 11 include, but are not limited to, plastics, glass, ceramics, and metals. The outer contour shape of the container 11 may include, but is not limited to, cylinders, cubes, cuboids, triangular prisms, and hexagonal prisms. The cross-sectional shape of the container cavity 111 includes, but is not limited to, regular or irregular shapes such as squares, circles, and triangles; the cross-section (including shape and size) of the container cavity 111 is approximately the same as the cross-section (including shape and size) of the aerosol generating matrix 300, thus improving the stability of the aerosol generating matrix 300 within the container cavity 111. In some embodiments of this application, the cross-sectional shapes of both the container cavity 111 and the aerosol generating matrix 300 are circular, and the cross-sectional dimensions of the container cavity 111 and the cross-sectional dimensions of the aerosol generating matrix 300 are substantially the same.

[0043] The material of the gas inlet 13 may include, but is not limited to, plastics, glass, ceramics, and metals. The outer contour shape of the gas inlet 13 may include, but is not limited to, cylinders, cubes, cuboids, triangular prisms, and hexagonal prisms. In some embodiments, the container 11 and the gas inlet 13 may be an integral structure, that is, the container 11 and the gas inlet 13 are a single structure manufactured using an integral molding process, which can improve the stability of the connection between the container 11 and the gas inlet 13 and ensure the normal operation of the atomizer 10. In other embodiments, the container 11 and the gas inlet 13 may be separate structures, that is, the container 11 and the gas inlet 13 are two different structures. The container 11 and the gas inlet 13 may be combined using a detachable connection method or a non-detachable connection method. Specifically, detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; non-detachable connection methods include, but are not limited to, bonding or welding.

[0044] In some embodiments, in the insertion direction of the aerosol generating matrix 300, the air inlet chamber 131 is located at the bottom of the receiving cavity 111 and communicates with the receiving cavity 111. Thus, when the aerosol generating matrix 300 is housed in the receiving cavity 111 and the aerosol generating matrix 300 is aspirated, outside air can flow through the air inlet chamber 131 to the bottom of the aerosol generating matrix 300. Figure 3 The aerosol generating matrix 300 is located at its lowest point (the bottom side of the matrix), allowing it to generate aerosols when heated. The cross-sectional shape of the air intake cavity 131 includes, but is not limited to, regular or irregular shapes such as square, circle, and triangle. For ease of understanding, the following embodiment uses a circular cross-sectional shape for the air intake cavity 131 as an example. It should be noted that when the cross-sectional shape of the air intake cavity 131 is circular, the air intake cavity 131 can be cylindrical; that is, the bottom wall 135 of the air intake cavity 13 is flat, and the side wall 137 of the air intake cavity 13 is cylindrical.

[0045] The air inlet 133 in the atomizer 10 mainly serves to connect the external environment and the air intake chamber 131; outside air can flow into the air intake chamber 131 through the air inlet 133. The cross-sectional shape of the air inlet 133 can be regular or irregular, and regular shapes include, but are not limited to, circles, squares, rectangles, and rhombuses. For ease of understanding, the following embodiment uses a circular cross-sectional shape of the air inlet 133 as an example. It should be noted that when the cross-sectional shape of the air inlet 133 is circular, the wall of the air inlet 133 can be cylindrical.

[0046] In some embodiments, the gas inlet 13 includes a bottom wall 135 and a side wall 137 extending from the periphery of the bottom wall 135 toward the accommodating body 11. The side wall 137 is connected to the accommodating body 11. A plurality of air inlets 133 are spaced apart on the side wall of the gas inlet 13. At least some of the air inlets 133 are located near the bottom wall 135 of the gas inlet 13 at positions corresponding to the air intake 131. And / or, at least some of the air inlets 133 are located near the side wall 137 of the gas inlet 13 at positions corresponding to the maximum range of the air intake direction in the radial direction Y.

[0047] In some embodiments of this application, a plurality of air inlets 133 form an air intake area and are used to allow outside air to flow into the air intake chamber. The air intake area at least partially corresponds to the periphery of the air intake chamber 131, that is, the air intake area at least partially corresponds to the position of the air intake chamber 131 in the axial direction X near the bottom wall 135 of the air intake 13; and / or, the air intake area at least partially corresponds to the position of the air intake chamber 131 in the radial direction Y corresponding to the maximum range of the air intake direction. For example, when the cross-sectional shape of the air intake chamber 131 is circular, the air intake area at least partially corresponds to the position of the air intake chamber 131 in the radial direction Y corresponding to the maximum range of the air intake direction passing through the center of the air intake chamber 131. This allows outside air to enter the edge region of the air intake chamber 131 through the air intake port 133. Compared to a single air intake port 133 that is connected to the center of the air intake chamber 131, the airflow dead zone in the air intake chamber 131 is smaller, thereby reducing the possibility of aerosol condensation and deposition in the air intake chamber 131 and improving the stability and reliability of the aerosol generation device 100.

[0048] It should be noted that, in some embodiments, the axial direction X of the air intake chamber 131 can be the direction extending along the central axis of the air intake chamber 131; the radial direction Y of the air intake chamber 131 can be the direction perpendicular to the axial direction X and intersecting the central axis of the air intake chamber 131.

[0049] In the atomizer 10 of this embodiment, the gas inlet 13 is provided with a plurality of spaced air inlets 1333, which form an air intake area for allowing outside air to flow into the air intake chamber 131. The air intake area at least partially corresponds to the periphery of the air intake chamber 131, thereby reducing the airflow dead zone in the air intake chamber 131, thus reducing or even avoiding the condensation and deposition of aerosols in the air intake chamber 131, preventing the flow of outside air from being blocked, and thereby improving the stability and reliability of the aerosol generating device 100. Furthermore, the arrangement of the air inlets 133 in this application can also increase the air intake area, which can further reduce the possibility of aerosol condensation and deposition in the air intake chamber 131, ensuring the normal operation of the aerosol generating device 100.

[0050] Furthermore, since the air intake chamber 131 is typically small in size, it is difficult for users to clean it when aerosol condenses and deposits on the bottom wall 135 of the air intake chamber 13, which will affect the user experience. However, the way the air intake hole 133 is designed in the atomizer 10 of this application can reduce or even avoid aerosol condensation and deposition in the air intake chamber 131, thereby avoiding the problem of the air intake chamber 131 being difficult to clean due to aerosol condensation and deposition, and thus improving the user experience.

[0051] Furthermore, compared to having only one air inlet 133, having multiple air inlets 133 can increase the jet velocity of the outside air and increase the jet area, thereby reducing the condensation and deposition of aerosols in the air inlet chamber 131, preventing the flow of outside air from being blocked, and ensuring the normal operation of the aerosol generating device 100.

[0052] The atomizer 10 will be further explained below with reference to the accompanying drawings.

[0053] Please see Figure 4 and Figure 5 ,or Figure 6 and Figure 7 In some embodiments, when at least a portion of the air inlet 133 corresponds to a position close to the bottom wall 135 of the gas inlet 13, the wall of the air inlet 133 is tangent to the bottom wall 135 of the gas inlet 13.

[0054] Specifically, in some embodiments, the tangency between the wall of the air inlet 133 and the bottom wall 135 of the gas inlet 13 can be such that the wall of the air inlet 133 (cylindrical) and the bottom wall 135 (planar) of the gas inlet 13 have only one common tangential surface at the contact point, and the two transition smoothly at the contact point. This ensures that outside air flows directly to the bottom wall 135 of the gas inlet 13, thereby reducing or even eliminating the airflow dead zone in the air intake chamber 131, reducing the possibility of aerosol condensation and deposition on the bottom wall 135 of the gas inlet 13, and thus improving the stability and reliability of the aerosol generation device 100, resulting in a better user experience.

[0055] In some embodiments, when at least a portion of the air inlet 133 corresponds to the position of the air inlet cavity 131 close to the side wall 137 of the air inlet 13 at the position corresponding to the maximum range of the air inlet direction in the radial direction Y, the wall of the air inlet 133 is tangent to the corresponding position of the side wall 137 of the air inlet 13.

[0056] Specifically, in some embodiments, the tangency between the wall of the air inlet 133 and the side wall 137 of the gas inlet 13 can be achieved by the following: in a cross-sectional view (a plane parallel to the radial direction Y), the wall of the air inlet 133 and the side wall 137 of the gas inlet 13 share only one common tangent at the contact point, and the two transition smoothly at the contact point. This ensures that outside air flows directly to the edge region of the air inlet chamber 131 in the radial direction Y, thereby reducing or even eliminating airflow dead zones in the air inlet chamber 131, reducing the possibility of aerosol condensation and deposition on the bottom wall 135 of the gas inlet 13, and thus improving the stability and reliability of the aerosol generation device 100, resulting in a better user experience.

[0057] In some embodiments, the central axes of the multiple air inlets 133 are parallel to each other. This ensures that the airflow direction of each air inlet 133 is consistent, preventing interference between different air inlets 133, thereby allowing outside air to enter the air intake chamber 131 evenly and improving air intake efficiency. On the other hand, the parallel multiple air inlets 133 are easier to manufacture, thereby improving the production efficiency of the atomizer 10.

[0058] Please see Figure 4 and Figure 5 In some embodiments, a plurality of air inlets 133 are arranged in an array, with each row of air inlets 133 having the same number of holes in the axial direction X of the air intake cavity 131. That is, the plurality of air inlets 133 can be arranged in a matrix on the sidewall 137 of the air intake 13, thereby increasing the area covered by the air inlets 133, i.e., increasing the air intake area, reducing the airflow dead zone in the air intake cavity 131, reducing the possibility of aerosol condensation and deposition on the bottom wall 135 of the air intake 13, and improving the stability and reliability of the aerosol generation device 100. For example, the array number of the plurality of air inlets 133 can be 4*5, that is, the number of holes in each row of air inlets 133 in the axial direction X of the air intake cavity 131 is 5.

[0059] Specifically, in some embodiments, when at least some of the air inlets 133 are located near the bottom wall 135 of the gas inlet 13 in the axial direction X, the wall of the bottom row of air inlets 133 can be tangent to the bottom wall 135 of the gas inlet 13 along the insertion direction of the aerosol generating matrix 300 (parallel to the axial direction X); when at least some of the air inlets 133 are located near the side wall 137 of the gas inlet 13 in the radial direction Y, the wall of the outermost row of air inlets 133 can be tangent to the side wall 137 of the gas inlet 13 along the circumference of the gas inlet 131.

[0060] Please see Figure 6 and Figure 7In other embodiments, a plurality of air inlets 133 are arranged in an array, and in the axial direction X of the air inlet cavity 131, the number of holes in the row of air inlets 133 closest to the bottom wall 135 of the air inlet 13 is greater than the number of holes in the other rows of air inlets 133.

[0061] Therefore, compared to having only one air inlet 133, this design not only ensures that outside air flows directly to the bottom wall 135 of the air inlet 13, reducing the dead zone in the air intake chamber 131, but also increases the air intake area, reducing the condensation and deposition of aerosol on the bottom wall 135 of the air intake chamber 131, thus improving the stability and reliability of the aerosol generating device 100. Furthermore, compared to a row of air inlets 133 closest to the bottom wall 135 of the air inlet 13 having the same number of holes as other rows of air inlets 133, the fewer openings in the air inlet 133 design improve the structural strength of the body 11, reduce the possibility of deformation and damage, extend the service life of the body 11, and consequently improve the stability and reliability of the atomizer 10.

[0062] Furthermore, in some embodiments, the number of holes in the multiple rows of air inlets 133 gradually increases in the direction from the accommodating cavity 111 to the air inlet cavity 131 (parallel to the axial direction X of the air inlet cavity 131). This allows for a larger number of air inlets 133 in the bottom row, ensuring a smaller dead zone in the airflow within the air inlet cavity 131 and reducing the condensation and deposition of aerosols on the bottom wall 135 of the air inlet cavity 131. It also allows for a more uniform arrangement of the air inlets 133 on the side wall 137 of the air inlet 13, reducing visual imperfections and improving the visual effect.

[0063] In other embodiments, the number of holes in the multiple rows of air inlets 133 varies irregularly in the direction from the accommodating cavity 111 to the air inlet cavity 131, and the row of air inlets 133 closest to the bottom wall 135 of the air inlet 13 has a greater number of holes than the other rows. For example, in the direction from the accommodating cavity 111 to the air inlet cavity 131, the side wall 137 of the air inlet 13 has four rows of air inlets 133, and the first row of air inlets 133 has 1 hole, the second row of air inlets 133 has 1 hole, the third row of air inlets 133 has 3 holes, and the fourth row of air inlets 133 has 5 holes.

[0064] Please see Figure 3In some embodiments, the diameter of the air intake 133 is greater than or equal to 0.20 mm and less than or equal to 0.40 mm. It should be noted that in some embodiments, the diameter of the air intake 133 can be any one or any value between any two of the following: 0.20 mm, 0.22 mm, 0.24 mm, 0.26 mm, 0.28 mm, 0.30 mm, 0.32 mm, 0.34 mm, 0.36 mm, 0.38 mm, and 0.40 mm. Preferably, the diameter of the air intake 133 can be 0.30 mm.

[0065] Specifically, the diameter of the air inlet 133 is greater than or equal to 0.20 mm and less than or equal to 0.40 mm. This can, on the one hand, prevent the air inlet 133 from being too small, which would result in excessive suction resistance and ensure normal inhalation for the user; on the other hand, it can prevent the air inlet 133 from being too large, which would result in low airflow velocity. This ensures that when outside air flows into the air inlet chamber 131, it can have a scouring effect on the bottom wall 135 and / or the side wall 137 of the air inlet 13, reducing the possibility of aerosol condensation and deposition in the air inlet chamber 131; and on the other hand, it can prevent the air inlet 133 from being too large, which would result in low structural strength of the body 11. This can reduce the possibility of deformation and damage to the body 11, extend the service life of the body 11, and improve the stability and reliability of the atomizer 10.

[0066] In some embodiments, the distance between two adjacent air intakes 133 is greater than or equal to 0.30 mm and less than or equal to 0.90 mm. It should be noted that in some embodiments, the distance between two adjacent air intakes 133 can be any one of 0.30 mm, 0.40 mm, 0.50 mm, 0.60 mm, 0.70 mm, 0.80 mm, and 0.90 mm, or any value between any two of these. Preferably, the distance between two adjacent air intakes 133 can be 0.60 mm.

[0067] Specifically, the distance between two adjacent air inlets 133 is greater than or equal to 0.30 mm and less than or equal to 0.90 mm. This can prevent the airflow between different air inlets 133 from interfering due to the distance between two adjacent air inlets 133 being too small, thereby improving the air intake efficiency and ensuring normal suction for the user. On the other hand, it can prevent the air intake area from being too large due to the distance between two adjacent air inlets 133 being too small, thereby reducing the dead zone of airflow in the air intake chamber 131 and reducing or even avoiding the condensation and deposition of aerosols on the bottom wall 135 of the air intake chamber 13.
