Description

Technical Field

[0001] This application relates to the field of aerosol generating device technology, and more specifically, to an air intake component and an aerosol generating device. Background Technology

[0002] Aerosol generators typically include an air inlet, an atomizing core, and a suction channel. The air inlet allows external gas to enter the device. After entering, the gas flows through the atomizing core, carrying the heated aerosol along the suction channel, where it is then inhaled by the user. To prevent the air inlet from remaining open when the device is not in use, thus allowing dust and other substances to enter, a gas regulating component is usually included. This component controls the opening degree of the air inlet. Because the gas flow rate within the air inlet is high, sudden changes in velocity cause a transition from laminar to turbulent flow. Vortices form between the gas and the edge membrane of the inlet. When these vortices detach, they generate periodic pressure pulsations, resulting in broadband noise. This broadband noise is perceptible to the human ear and therefore can be heard by the user.

[0003] Existing aerosol generating devices can only control the opening degree of the air inlet to reduce broadband noise. However, if a large gas flow is required to assist in aerosol generation and extraction, the diameter of the air inlet needs to be large, which will lead to broadband noise. If the flow area of ​​the air inlet is reduced, the amount of aerosol extracted will be less, resulting in a poor user experience. Utility Model Content

[0004] The technical problem to be solved by the embodiments of this application is that the air intake components of existing aerosol generating devices result in poor user experience or noise.

[0016] The elastic protrusions are multiple in number and are symmetrically distributed on the elastic part along the direction perpendicular to the air regulating channel to the first air inlet.

[0021] Compared with the prior art, the embodiments of this application have the following main advantages:

[0022] The gas regulating component can be moved or rotated to connect one or more of the flow-limiting orifices with the first air inlet, thereby reducing the gas flow area and thus reducing broadband noise.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0035] In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or operating state, specifically the orientation shown in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "comprising" means "including but not limited to". The terms first, second, third, etc., are used merely as illustrative purposes and do not impose numerical requirements or establish a numerical order.

[0036] In this application, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. A and B can be singular or plural.

[0037] In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, "at least one of a, b, or c," or "at least one of a, b, and c," can both mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0038] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0039] To solve the above problems, please refer to... Figures 1-5 This application provides an intake assembly, including:

[0040] The main body is provided with a first air inlet 30 and a suction channel 50, and the first air inlet 30 is connected to the suction channel 50.

[0041] An air regulating component 100 blocks the first air inlet 30 and is provided with a plurality of flow limiting holes 121 for moving or rotating relative to the first air inlet 30 so that one or more of the flow limiting holes 121 are connected to the first air inlet 30.

[0042] In this embodiment, the usage process of the air intake assembly is as follows: Figure 1 As shown, initially, the air regulating component 100 blocks the first air inlet 30. Then, when air needs to enter through the first air inlet 30, the air regulating component 100 moves or rotates to connect one or more of the flow-limiting orifices 121 with the first air inlet 30. As the airflow passes through the flow-limiting orifices 121, its flow area decreases, thus reducing broadband noise. When it is necessary to increase the amount of aerosol drawn in, the air regulating component 100 moves or rotates again to increase the number of flow-limiting orifices 121 and the first air inlet 30 that are connected. At this time, the rate at which external gas enters the body increases, and the rate of aerosol generation also increases, but the diameter of a single flow-limiting orifice remains unchanged, thus still preventing broadband noise generation.

[0043] Since the first air inlet 30 can be connected to multiple flow-limiting holes 121, it can be seen that the diameter of a single flow-limiting hole 121 is smaller than that of the first air inlet 30. Therefore, when the airflow passes through multiple flow-limiting holes 121 at the same time, it can increase the amount of external gas entering the main body, but will not generate broadband noise due to the large flow area of ​​the gas entering the main body.

[0044] In summary, the air conditioning component 100 of this application can reduce the noise heard by the user while maintaining a high aerosol generation rate, thereby improving the user experience.

[0045] It should be understood that the main body of this application may include an atomizing core 60, at least part of which is located within the suction channel 50, for heating the aerosol generating medium to generate aerosol. Figure 3 The direction indicated by the middle arrow and the dashed line is the flow path for external gas to enter the main body.

[0046] Further, please refer to Figures 1-3 The main body is provided with an air regulating channel 40, which is connected to the first air inlet 30. At least part of the air regulating component 100 is located in the air regulating channel 40 and moves along the direction from the air regulating channel 40 to the first air inlet 30, so as to block the first air inlet 30 or connect with the flow limiting hole 121.

[0047] In this embodiment, the direction from the gas regulating channel 40 to the first air inlet 30 is the Z direction in the figure. The gas regulating channel 40 can accommodate and restrict the position of the gas regulating component 100, so that the gas regulating component 100 can move back and forth toward the first air inlet 30, thereby achieving the effect of precisely blocking or controlling the gas flow of the first air inlet 30.

[0048] Further, please refer to Figure 1 The air regulating component 100 includes a blocking part 110 and a flow limiting part 120 connected to each other. A flow limiting hole 121 is disposed in the flow limiting part 120, and a plurality of flow limiting holes 121 are sequentially disposed in the flow limiting part 120 along the movement path of the air regulating component 100.

[0049] In this embodiment, when the blocking part 110 is located at the first air inlet 30, it can effectively block the first air inlet 30. When the flow-limiting part 120 is located at the first air inlet 30, it can adjust the number of flow-limiting holes 121 and the first air inlet 30 through its own proportion in the first air inlet 30, thereby controlling the amount of aerosol generated. It should be understood that when the movement path of the air regulating component 100 is a straight line, the first air inlets 30 are arranged sequentially along the straight line; if its movement path is arc-shaped, the first air inlets are arranged sequentially in an arc shape along its movement path.

[0050] It should be understood that when the blockage part 110 abuts against the gas regulating passage 40, the flow restricting part 120 may not abut against the gas regulating passage 40. Specifically, as... Figure 3 As shown, the flow-limiting part 120 is thicker along the X direction in the figure, thus it abuts against the air regulating channel 40. At this time, the regulating member is restricted within the air regulating channel 40 by the blocking part 110. Even if the thickness of the flow-limiting part 120 is small and it does not contact the air regulating channel 40, the regulating member can maintain its own position and balance. Therefore, the thickness of the flow-limiting part 120 can be smaller than that of the blocking part 110, thereby reducing the production cost of the regulating member. The blocking part 110 can be elastic; in this case, the blocking part 110 can be easily installed into the air regulating channel 40 through deformation, and can also reduce its rigid friction with the air regulating channel 40 through deformation.

[0051] Further, please refer to Figures 1-6 The flow area ratio between the flow-limiting orifice 121 and the first air inlet 30 is 1:(2~10); and / or,

[0052] The opening of the flow-limiting orifice 121 is provided with a rounded corner; and / or,

[0053] The air regulating component 100 is disposed inside the main body and also includes a toggle part 130. The toggle part 130 is disposed along the length direction of the first air inlet 30, and one end of the toggle part 130 extends to the outside of the main body along the depth direction of the first air inlet 30.

[0054] In this embodiment, when the flow area ratio of the flow-limiting orifice 121 to the first air inlet 30 is 1:(2~10), it can effectively reduce the gas flow rate entering the main body through the first air inlet 30, thereby reducing the generation of broadband noise. Figures 5-6 As shown, when the opening of the flow-limiting orifice 121 is rounded, the rounded corner can prevent airflow separation from forming large-scale vortices. Simultaneously, it prevents pressure pulsations caused by the collision of the separated airflow with the main airflow after right-angle separation. In summary, the rounded corner further reduces the noise generated by gas entering the main body. The toggle part 130 allows the user to easily control the movement of the adjusting component along the Z-axis direction, thereby controlling the flow area of ​​the flow-limiting orifice 121 and the first air inlet 30.

[0055] Further, please refer to Figure 5 and Figure 6 The air regulating component 100 includes an elastic protrusion 151, which is arranged along the direction from the air regulating channel 40 to the first air inlet 30 and abuts against the air regulating channel 40.

[0056] In this embodiment, the elastic protrusion 151 is arranged along the direction (Z direction) from the air regulating channel 40 to the first air inlet 30, which can be understood as the length direction of the elastic protrusion 151 being the Z direction. First, the elastic protrusion 151 can abut against the air regulating channel 40, thereby limiting the movement direction of the air regulating component 100. Second, the elastic protrusion 151 is elastic, so when it abuts against the air regulating channel 40 and slides along the air regulating channel 40, it can provide a flexible damping feel, thereby improving the user experience.

[0057] Further, please refer to Figure 5 and Figure 6 The air regulating component 100 includes an elastic part 150, a blocking part 110 and a flow limiting part 120 connected to each other. The flow limiting hole 121 is disposed in the flow limiting part 120. The blocking part 110 is provided with a deformation groove 140. The elastic part 150 is located in the deformation groove 140.

[0058] The elastic protrusions 151 are multiple and are symmetrically distributed on the elastic part 150 along the direction perpendicular to the air regulating channel 40 to the first air inlet 30.

[0059] In this embodiment, the flow-limiting part 120 is provided with a flow-limiting orifice 121, and its structural strength is lower than that of the blocking part 110 (it is easy to shrink or deform under force). Therefore, the elastic part 150 is provided on the blocking part 110 to avoid the flow-limiting part 120 from further decreasing in strength when the deformation groove 140 is opened in the flow-limiting part 120. At the same time, since the elastic protrusion 151 is provided on the elastic part 150, the contact force between the elastic protrusion 151 and the air regulating channel 40 can be adjusted by replacing different elastic parts 150, thereby adjusting the feel of the air regulating component 100 according to the user's needs.

[0060] Furthermore, there is a gap between the elastic protrusion 151 and the sidewall of the deformation groove 140.

[0061] In this embodiment, the elastic protrusion 151 is located in the deformation groove 140. When it deforms, it can be compressed into the space within the deformation groove 140, thereby providing deformation space for the elastic protrusion. This avoids the elastic protrusion 151 having a large frictional force with the air regulating channel 40 under assembly tolerance, which would affect the user's control of the movement of the air regulating component 100.

[0062] It should be understood that the elastic protrusion 151 can be made of materials such as damping silicone or rubber. A sliding groove can be provided in the air regulating channel 40, and the elastic protrusion 151 is located in the sliding groove. In this case, the sliding groove and the elastic protrusion 151 can further restrict the position of the air regulating component 100. When a sliding groove is provided, the side of the air regulating component 100 facing the air regulating channel 40 can abut against the air regulating channel 40, or only the elastic protrusion 151 can contact the sliding groove. If the side of the air regulating component 100 facing the air regulating channel 40 contacts the air regulating channel 40, then the air regulating component 100 is doubly fixed by the elastic protrusion 151 and its own sidewall, resulting in strong structural stability. Furthermore, because the elastic protrusion 151 is located in the sliding groove, the contact area between the elastic protrusion 151 and the air regulating channel 40 increases (from single-sided contact to three-sided contact), thus providing a better feel when the air regulating component 100 slides.

[0063] Further, please refer to Figures 4-6Along the direction from the air regulating channel 40 to the first air inlet 30, the deformation groove 140 includes a first sub-deformation groove 141 and a second sub-deformation groove 142. The first sub-deformation groove 141 is connected to the second sub-deformation groove 142 and is perpendicular to the direction from the air regulating channel 40 to the first air inlet 30. The groove width of the first sub-deformation groove 141 is smaller than the groove width of the second sub-deformation groove 142. There are at least four elastic protrusions 151, and at least two elastic protrusions 151 are symmetrically arranged in the first sub-deformation groove 141 along the groove width direction of the first sub-deformation groove 141. At least two elastic protrusions 151 are arranged in the second sub-deformation groove 142 along the groove width direction of the second sub-deformation groove 142.

[0064] Further, please refer to Figure 3 The main body is provided with a liquid storage chamber 80, and at least part of the suction channel 50 is located in the liquid storage chamber 80. The outer side wall of the liquid storage chamber 80 and the inner side wall of the main body together define the gas regulating channel 40. The elastic part 150 is provided with elastic protrusions 151 on both sides, and the elastic protrusions 151 on both sides abut against the outer side wall of the liquid storage chamber 80 and the inner side wall of the main body, respectively.

[0065] In this embodiment, the outer wall of the liquid storage cavity 80 and the inner wall of the main body together define the gas regulating channel 40, so there is no need to process the gas regulating channel 40 separately, thereby reducing the production cost of the air intake assembly; at the same time, when the elastic protrusion 151 on the elastic part 150 abuts against the outer wall of the liquid storage cavity 80 and the inner wall of the main body, the two sides of the elastic part 150 at opposite positions are subjected to force at the same time, which can prevent it from shaking and falling off the gas regulating channel 40.

[0066] In this embodiment, firstly, the nozzle 1 is typically shaped with a narrow top and a wide bottom. Therefore, the width of the first sub-groove 141 (in the Y direction of the figure) is smaller than the width of the second sub-groove 142, thus adapting to existing nozzles 1 and improving the versatility of the air regulating component 100. Secondly, four elastic protrusions 151 are located in the first sub-groove 141 and the second sub-groove 142 respectively, and are symmetrically distributed. Therefore, given that the width of the first sub-groove 141 is smaller than that of the second sub-groove 142, the four elastic protrusions 151 located in the first sub-groove 141 and the second sub-groove 142 are symmetrically distributed. The elastic protrusion 151 in the sub-shaped groove 141 can play a central supporting role (centered relative to the symmetry plane of the first sub-shaped groove 141), while the elastic protrusion 151 in the second sub-shaped groove 142 can play a supporting role located on the outside (far away from the symmetry plane of the first sub-shaped groove 141). At this time, the contact surface between the air regulating component 100 and the air regulating channel 40 can have multiple points in the Z and Y directions, thereby improving the stability of the air regulating component 100 during movement.

[0067] Further, please refer to Figures 2-4The main body includes a first outer shell 10 and a second outer shell 20. An air inlet groove is provided on the side of the first outer shell 10 facing the second outer shell 20, and a positioning protrusion 21 is provided at the opening of the air inlet groove. A positioning hole is provided on the side of the second outer shell 20 facing the first outer shell 10, and the positioning protrusion passes through the positioning hole to connect the first outer shell 10 and the second outer shell 20; and / or,

[0068] The air regulating component 100 is an elastic component.

[0069] In this embodiment, during the assembly of the first housing 10 and the second housing 20, there may be assembly errors, which may cause the connection between the two to be misaligned, resulting in a decrease in the stability of the air intake assembly. At the same time, after the air regulating component 100 is installed on the second housing 20, it needs to abut against the inner wall of the first housing 10, which may easily push the first housing 10 into a bulging state, thereby causing a decrease in the stability of the air intake assembly.

[0070] Therefore, the positioning protrusion 21 in this embodiment can cooperate with the positioning hole to fix the first outer shell 10 and the second outer shell 20, and also serve to guide the two to connect precisely. At the same time, the design of the air inlet groove allows the air regulating component 100 to be inserted into the second outer shell 20 from top to bottom without considering the influence of the actuating part 130 on the installation of the air regulating component 100 and the second outer shell 20. Therefore, the air inlet groove can improve the assembly efficiency of the air regulating component 100 and the second outer shell 20. Then, after the first outer shell 10 and the second outer shell 20 are connected, the air inlet groove can form an air inlet hole. At this time, the actuating part 130 will be abutted by the air regulating hole during the movement of the air regulating component 100, thereby limiting the maximum movement of the air regulating component 100 and preventing it from falling off to the preset position.

[0071] When the air regulating component 100 is an elastic component, its elastic material can produce slight deformation when the airflow passes through the flow limiting hole 121 to reduce vortex generation and thus reduce broadband noise.

[0072] Accordingly, please refer to Figure 7 and Figure 8 This application also provides an aerosol generating device, which includes an air intake component, an atomizing component, and a main unit 2 obtained in any of the above embodiments.

[0073] In this embodiment, since the aerosol generating device includes the air intake component of any of the above embodiments, the air regulating component 100 can enable the aerosol generating device to maintain a high aerosol generation rate while reducing the noise heard by the user, thereby improving the user experience.

[0074] It should be understood that, such as Figure 7 and Figure 8As shown, the aerosol generating device includes a nozzle 1 and a main unit 2. The main unit 2 houses components such as a circuit board and a battery. In this embodiment, the air intake component is located on the nozzle 1 instead of the main unit 2. The nozzle 1 has a bottom cover that seals the bottom of the second outer casing 20, thereby preventing airflow from the first air intake 30 and aerosol (or aerosol generating medium) in the nozzle 1 from leaking into the main unit 2, which would otherwise affect the efficiency and lifespan of the circuit board, battery, and other components due to external liquids and gases. Therefore, when the air intake component is located on the nozzle 1, it can prevent liquid from penetrating the main unit 2. An atomizing component may be installed inside the nozzle 1. The atomizing component is usually located within the suction channel 50 and includes an atomizing core 60. It is typically controlled by the main unit 2 via an electrical signal to heat the aerosol generating medium from the liquid storage chamber 80, thereby generating aerosol within the suction channel 50.
