[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, electronic atomization devices that can heat liquid or solid aerosol-generating substrates to generate aerosols are used in different fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.
[0003] Generally, an electronic atomization device atomizes an aerosol-generating substrate, which is a substrate material that can generate an aerosol after atomization. However, during the inhalation process, the conventional electronic atomization device makes a lot of noise and has a poor user experience. Utility Model Content

It can be understood that, in general, the cross section of the throttle hole is perpendicular to the axial direction of the throttle hole, which is equivalent to a horizontal plane, and the air inlet end is inclined relative to the cross section, so that the flare formed at the air inlet end during injection molding is located in the inclined inclined plane. In this way, when the external airflow flows to the air inlet end, the airflow and the flare will not collide vertically. Compared with the horizontally set air inlet end, the force on the flare of the inclined air inlet end is reduced, so that the collision frequency of the flare is reduced, thereby reducing noise. At the same time, the air inlet end is inclined, and the air inlet area is increased to reduce the amplitude of the sudden reduction in the area of the air flow channel when the airflow suddenly enters the throttle hole, so as to further reduce noise.
[0008] In some embodiments, a boss is protruding from the bracket body, the throttle hole is opened through the boss, the air inlet end of the throttle hole is formed on the bottom surface of the boss, and the bottom surface of the boss is inclined.

[0010] In some embodiments, the first inner side wall is extended along the flow direction of the airflow in the air inlet cavity, and the angle between the bottom surface of the boss and the first inner side wall is an obtuse angle.
[0011] In some of the embodiments, the angle between the plane where the air inlet end is located and the axis of the throttle hole is in the range of 115°-155°.
[0012] In some of the embodiments, the air inlet end of the throttle hole is provided with a chamfer.

[0028] As described in the background technology, traditional electronic atomization devices make a lot of noise during the suction process. Generally speaking, during the suction process, the external airflow needs to pass through the various airflow channels in the electronic atomization device before entering the atomizer, and finally the aerosol-generated matrix flows out of the atomizer with the atomized aerosol for the user to inhale and consume. Therefore, each position on the airflow path may cause suction noise. After studying and analyzing the various components on the airflow path, it was finally found that a major noise source causing the suction noise is in the throttle hole.
[0029] Specifically, the throttle hole is located upstream of the atomizer and is used to control parameters such as the airflow rate and pressure entering the atomizer. The throttle hole is generally manufactured using an injection molding process. When molding a battery holder with a throttle hole, the front and rear molds of the injection mold have a through-structure, and the front mold is a pin structure. The pins of the rear mold and the front mold collide, so it is easy to produce a peak at the place where the air inlet end of the throttle hole collides, which will cause noise during the inhalation process because the airflow blows the peak.
[0030] See also Figure 1-Figure 2 In order to solve this technical problem, some embodiments of the present application provide an electronic atomization device 100, including a power supply assembly and an atomizer 10, the power supply assembly is used to supply power to the atomizer 10, and the atomizer 10 heats the atomized aerosol to generate a matrix after being powered on, forming an aerosol for the user to inhale and consume.
[0031] The power supply assembly includes a battery bracket 40 and a battery 60, and the battery 60 is arranged on the battery bracket 40, so that the power supply is installed through the battery bracket 40. In addition, the battery bracket 40 includes a bracket body 41, and a throttle hole 42 for communicating with the atomizer 10 is opened on the bracket body 41. The external airflow enters the atomizer 10 through the throttle hole 42, and the airflow pressure and flow rate and other parameters entering the atomizer 10 are controlled by the throttle hole 42.
[0032] See also Figure 2-Figure 4According to some embodiments of the present application, the throttle hole 42 has an air inlet end, and the plane where the air inlet end is located is inclined relative to the transverse plane of the throttle hole 42. It can be understood that, generally speaking, the cross section of the throttle hole 42 is perpendicular to the axial direction of the throttle hole 42, which is equivalent to a horizontal plane, and the air inlet end is inclined relative to the cross section, so that the flare formed at the air inlet end during injection molding is located in the inclined inclined plane. In this way, when the external airflow flows to the air inlet end, the airflow and the flare will not collide vertically. Compared with the horizontally set air inlet end, the force on the flare of the inclined air inlet end is reduced, so that the collision frequency of the flare is reduced, thereby reducing noise. At the same time, the air inlet end is inclined, and the air inlet area is increased to reduce the amplitude of the sudden reduction in the area of the air flow channel when the airflow suddenly enters the throttle hole 42, so as to further reduce noise.
[0033] Furthermore, a boss 43 is protruding from the bracket body 41, and the throttle hole 42 is formed through the boss 43. The air inlet end of the throttle hole 42 is formed on the bottom surface 431 of the boss 43, and the bottom surface 431 of the boss 43 is inclined. In this way, the throttle hole 42 is formed by providing the boss 43, and the bottom surface 431 of the boss 43 is located at the air inlet end of the throttle hole 42. Therefore, the bottom surface 431 of the boss 43 is set as an inclined surface, and the air inlet end of the throttle hole 42 can also be constructed to be inclined.
[0034] According to some embodiments of the present application, the support body 41 has an air inlet cavity 50, the boss 43 is protrudingly arranged on the first inner side wall of the air inlet cavity 50, and the throttle hole 42 is connected with the air inlet cavity 50. In this way, the air inlet cavity 50 is arranged on the support body 41, and the external airflow can first flow to the air inlet cavity 50, and then flow to the throttle hole 42 and enter the atomizer 10, so that the airflow flowing to the throttle hole 42 is collected and gathered by the air inlet cavity 50, so as to facilitate the guidance of the airflow into the throttle hole 42.
[0035] In addition, the boss 43 is protrudingly arranged on the first inner wall of the air inlet cavity 50, which is equivalent to being arranged on the edge of a certain side wall. The boss 43 is not suspended in the air inlet cavity 50. After the airflow flows along the first inner wall, it can smoothly flow into the throttle hole 42 of the boss 43, thereby improving the smoothness of the airflow.
[0036] Specifically in this embodiment, the first inner side wall is extended along the air flow direction of the airflow in the air intake cavity 50, and the angle A between the bottom surface 431 of the boss 43 and the first inner side wall is an obtuse angle, so that the bottom surface 431 of the boss 43 is inclined upstream of the air flow, and when the airflow blows toward the air intake side of the throttle hole 42 on the boss 43, the flow direction of the airflow forms an obtuse angle with the air intake side, and the front force on the air intake side is smaller, thereby reducing noise.
[0037] According to some embodiments of the present application, the air intake end of the throttle hole 42 is provided with a chamfer, thereby forming a trumpet-shaped air intake side, further increasing the air intake area of the air intake side, and further reducing noise.
[0038] Specifically in one embodiment, the chamfer is a rounded corner with a radius of 0.5mm-10mm, so that the size of the rounded corner is controlled within a suitable range to ensure the noise reduction effect. It can be understood that the chamfer is an oblique angle, which is inclined at a certain angle relative to the outward expansion, and can also increase the intake area on the intake side.
[0039] According to some embodiments of the present application, the diameter of the throttle hole 42 is D, the length of the throttle hole 42 is L, and the ratio of D:L is in the range of 1:3 to 1:6. It can be understood that the length L of the throttle hole 42 is the length of the throttle hole 42 at the center axis.
[0040] Moreover, the larger the diameter of the throttle hole 42 is, the slower the air flow rate becomes when the length of the throttle hole 42 is the same and the suction force is the same; conversely, the smaller the diameter is, the faster the air flow rate becomes. In addition, the longer the length L of the throttle hole 42 is, the greater the pressure of the air in the throttle hole 42 becomes under the same diameter and suction force, and the air flow rate becomes slower when passing through the air inlet end, so the longer the length of the throttle hole 42 is, the slower the air flow rate at the air inlet end. Therefore, when the ratio of D:L is too small, the noise is relatively large; when the ratio of D:L is too large, the diameter of the throttle hole 42 is too small, and the mold needle for making the throttle hole 42 is easy to break, which is not conducive to mass production; when the ratio of D:L is in the range of 1:3 to 1:6, the ratio of D:L is within a reasonable range, the noise reduction effect is better, and it is easy to produce.
[0041] According to some embodiments of the present application, the present application also provides a power supply assembly, including a battery 60 and a battery holder 40 as described in any of the above embodiments, wherein the battery 60 is disposed on the battery holder 40, the battery 60 is installed through the battery holder 40, and the airflow to the atomizer 10 is adjusted through the throttle hole 42 on the battery holder 40.
[0042] Furthermore, the throttle hole 42 has an air inlet end, and the plane where the air inlet end is located is inclined relative to the transverse plane of the throttle hole 42. It can be understood that generally speaking, the cross section of the throttle hole 42 is perpendicular to the axial direction of the throttle hole 42, which is equivalent to a horizontal plane, and the air inlet end is inclined relative to the cross section, so that the flash formed at the air inlet end during injection molding is located in the inclined slope.
[0043] In this way, when the external airflow flows to the air inlet end, the airflow and the blaze will not collide vertically. Compared with the horizontal air inlet end, the force on the blaze of the air inlet end is reduced by setting the air inlet end at an angle, so that the collision frequency of the blaze is reduced, thereby reducing noise. At the same time, the air inlet end is set at an angle, and the air inlet area is increased to reduce the amplitude of the sudden reduction of the air flow channel area when the air flow suddenly enters the throttle hole 42, so as to further reduce noise.
[0044] According to some embodiments of the present application, the present application further provides a battery holder 40 as described in any of the above embodiments, the battery holder 40 includes a holder body 41, the holder body 41 is provided with a throttle hole 42 for communicating with the atomizer 10, the external airflow enters the atomizer 10 through the throttle hole 42, and the airflow pressure and flow rate and other parameters entering the atomizer 10 are controlled by the throttle hole 42.
[0045] Furthermore, the throttle hole 42 has an air inlet end, and the plane where the air inlet end is located is inclined relative to the transverse plane of the throttle hole 42. It can be understood that, generally speaking, the cross section of the throttle hole 42 is perpendicular to the axial direction of the throttle hole 42, which is equivalent to a horizontal plane, and the air inlet end is inclined relative to the cross section, so that the flare formed at the air inlet end during injection molding is located in the inclined inclined plane. In this way, when the external airflow flows to the air inlet end, the airflow and the flare will not collide vertically. Compared with the horizontally set air inlet end, the force on the flare of the inclined air inlet end is reduced, so that the collision frequency of the flare is reduced, thereby reducing noise. At the same time, the air inlet end is inclined, and the air inlet area is increased to reduce the amplitude of the sudden reduction in the area of the air flow channel when the airflow suddenly enters the throttle hole 42, so as to further reduce noise.
[0046] Furthermore, a boss 43 is protruding from the bracket body 41, and the throttle hole 42 is formed through the boss 43. The air inlet end of the throttle hole 42 is formed on the bottom surface 431 of the boss 43, and the bottom surface 431 of the boss 43 is inclined. In this way, the throttle hole 42 is formed by providing the boss 43, and the bottom surface 431 of the boss 43 is located at the air inlet end of the throttle hole 42. Therefore, the bottom surface 431 of the boss 43 is set as an inclined surface, and the air inlet end of the throttle hole 42 can also be constructed to be inclined.
[0047] According to some embodiments of the present application, the support body 41 has an air inlet cavity 50, the boss 43 is protrudingly arranged on the first inner side wall of the air inlet cavity 50, and the throttle hole 42 is connected with the air inlet cavity 50. In this way, the air inlet cavity 50 is arranged on the support body 41, and the external airflow can first flow to the air inlet cavity 50, and then flow to the throttle hole 42 and enter the atomizer 10, so that the airflow flowing to the throttle hole 42 is collected and gathered by the air inlet cavity 50, so as to facilitate the guidance of the airflow into the throttle hole 42.
[0048] In addition, the boss 43 is protrudingly arranged on the first inner wall of the air inlet cavity 50, which is equivalent to being arranged on the edge of a certain side wall. The boss 43 is not suspended in the air inlet cavity 50. After the airflow flows along the first inner wall, it can smoothly flow into the throttle hole 42 of the boss 43, thereby improving the smoothness of the airflow.
[0049] Specifically in this embodiment, the first inner side wall is extended along the air flow direction of the airflow in the air intake cavity 50, and the angle between the bottom surface 431 of the boss 43 and the first inner side wall is an obtuse angle, so that the bottom surface 431 of the boss 43 is inclined upstream of the air flow, and when the airflow blows toward the air intake side of the throttle hole 42 on the boss 43, the flow direction of the airflow forms an obtuse angle with the air intake side, and the front force on the air intake side is smaller, thereby reducing noise.
[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
