Description

Technical Field

[0001] The present application relates to the technical field of atomizing devices, and more specifically, to a microphone assembly and an atomizing device. Background Art

[0002] Existing atomizers typically consist of an airway, a microphone assembly, and a heating element. When a user draws on the atomizer, external air flows through the microphone assembly, triggering the heating element to heat the material inserted into the atomizer. This heating process produces an aerosol, which is inhaled through the airway.

[0003] After the user completes the puff, some external moist air or backflow aerosol may enter the atomizer through the airway. This moist air or backflow aerosol often flows to the microphone assembly, causing liquid contamination on the microphone assembly surface and affecting the sensitivity of the microphone assembly. After the microphone assembly sensitivity is affected, it may be triggered by the backflowing air or the air entering when the atomizer is shaken, causing the atomizer to activate incorrectly, seriously reducing the user's efficiency and increasing the loss of the heated material.

[0004] In summary, the microphone assembly of the existing atomization device is easily contaminated by liquid, resulting in changes in its own sensitivity. Utility Model Content

[0038] Various embodiments of the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a hard limitation on the scope of the present application; therefore, the range description should be considered to have specifically disclosed all possible sub-ranges and single numbers within the range.

In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range.

[0039] Please refer to Figure 1 The embodiment of the present application provides a microphone assembly 100, which includes:

[0040] Microphone 130;

[0041] The filter element 120 is used to filter liquid;

[0042] The main body 110 has a return air duct disposed therein, the return air duct including a first air inlet 112 and a first air outlet (not shown in the figure), at least part of the microphone 130 is located in the return air duct and close to the first air outlet, and the filter element 120 is located in the return air duct and between the microphone 130 and the first air inlet 112.

[0043] In this embodiment, the return air duct can make the return gas flowing to the location of the microphone 130 flow along a preset path, that is, from the first air inlet 112 to the first air outlet ( Figure 1 In the X direction, the backflow gas is prevented from contacting the microphone 130 through the gaps of the remaining components after being dispersed and unable to be gathered. At the same time, because the filter 120 is located between the microphone 130 and the first air inlet 112, the liquid in the backflow gas or the atomized liquid in the atomizing device will first contact the filter 120 before contacting the microphone 130, and then be removed by the filter 120, so as to avoid liquid contamination of the surface of the microphone 130, prevent the sensitivity of the microphone 130 from changing, and improve the stability of the microphone 130.

[0044] It should be understood that the filter element 120 includes various structures such as filter cotton, filter mesh, and drying device.

[0045] For further information, please refer to Figure 1 and Figure 2 Filter 120 is a cotton filter that forms an interference fit with the return airway. It also has a through-hole 121, one end of which connects to the first air inlet 112 and the other end to the microphone 130. Filter 120 filters liquids including aerosols that flow back during inhalation, water vapor that enters the atomizer from the outside environment, and some of the atomized liquid stored within the atomizer. Therefore, filter 120 prevents some of the atomized liquid within the atomizer from contacting the microphone 130.

[0046] In this embodiment, the filter cotton is inherently elastic and can achieve an interference fit with the return air duct through elastic deformation. Therefore, it can be quickly assembled with the main body 110, thereby improving the production efficiency of the microphone assembly 100. The filter cotton filters liquid by absorbing moisture from the return gas. If the return gas carries too much moisture and the return gas flow rate is too high at the same time, the filter cotton will become saturated with water, resulting in some moisture still contacting the microphone 130. The through hole 121 allows the moisture absorbed by the filter cotton to flow out through the through hole 121. In this case, the through hole 121 can be tilted downward from the first air inlet 112 to allow the moisture flowing out of the through hole 121 to flow out of the return air duct, thereby preventing moisture accumulation on the filter cotton and contamination of the microphone 130.

[0047] For further information, please refer to Figure 1 and Figure 2 The ratio of the cross-sectional area of ​​the through hole 121 to the cross-sectional area of ​​the filter element 120 is 0.1 to 0.4.

[0048] In this embodiment, if the range of the through hole 121 is too large, too much backflow gas will pass through the filter element 120, resulting in the filter element 120 being unable to fully block moisture, and further causing the microphone 130 to be contaminated by moisture. If the range of the through hole 121 is too small, the through hole 121 will not be able to effectively allow moisture to flow out, and further causing the filter element 120 to be saturated with water. Therefore, the ratio range of the cross-sectional area of ​​the through hole 121 to the cross-sectional area of ​​the filter element 120 in the embodiment of the present application can both prevent the backflow gas from carrying too much moisture through the filter element 120 and prevent the filter element 120 from being saturated with water. It should be understood that the cross section is parallel to Figure 1 The YZ plane in .

[0049] For further information, please refer to Figures 1 to 2 The main body 110 is provided with an abutting protrusion 117, which is located on the side where the first air outlet is located. An air guide groove is provided on the side of the abutting protrusion 117 away from the first air inlet 112, and one end of the air guide groove is connected to the first air inlet 112.

[0050] In this embodiment, when the microphone assembly 100 is installed on the atomizing device 10, the side of the microphone assembly 100 provided with the first air inlet 112 is usually in contact with the external device. However, if the first air inlet 112 is completely blocked, the external air cannot be discharged. Figure 2 Air enters the USB air vent 410, thereby affecting the use of the atomizing device 10 or causing negative pressure to be generated in the atomizing device 10, making it inconvenient for the user to inhale.

[0051] Therefore, the abutting protrusion 117 in the embodiment of the present application is used to abut against the external device to complete the installation of the microphone assembly 100. At this time, the side of the microphone assembly 100 provided with the first air inlet 112 can be completely blocked, and the external air is only introduced into the return air duct through the air guide groove. At this time, the gas flow path is as follows Figure 1 As shown in the third path 40, that is, the installation of the microphone assembly 100 is achieved while avoiding the first air inlet 112 of the microphone assembly 100 being completely blocked and unable to take in air. It should be understood that the air guide groove can be as follows Figure 1 The open groove shown here requires the abutment protrusion 117 to abut against an external device so that the air guide groove can form a complete channel. The air guide groove can also be a through groove. In this case, the air guide groove is shaped like a hole and its inner wall is not exposed to the external environment. In this case, the channel in the air guide groove does not need to be defined by an external device.

[0052] For further information, please refer to Figure 1 and Figure 2 The air guide groove includes a second air inlet 113, a second air outlet 115 and a buffer air channel 114. Along the direction from the second air inlet 113 to the second air outlet 115, the cross-sectional area of ​​the buffer air channel 114 is greater than the cross-sectional area of ​​the second air inlet 113; and / or

[0053] A buffer groove 116 is provided at the bottom of the air guide groove.

[0054] In this embodiment, Figure 1 The cross-sections of the buffer air duct 114 and the second air inlet 113 are parallel to the ZX plane. Since the cross-sectional area of ​​the buffer air duct 114 is larger than the cross-sectional area of ​​the second air inlet 113, when the gas enters the buffer air duct 114 from the second air inlet 113, the gas enters the buffer air duct 114 in a divergent manner. At this time, the buffer air duct 114 can play a role in reducing the gas flow rate, thereby avoiding the backflow gas flow rate being too fast, resulting in the filter element 120 being unable to fully filter water, and can also avoid the filter element 120 absorbing water at a rate greater than the rate of water loss.

[0055] When the abutting protrusion 117 abuts an external device, the buffer groove 116 is located at the bottom of the air guide groove, leaving the buffer protrusion exposed while the air guide groove is blocked by the external device. At this time, when external air quickly enters the buffer air channel 114 from the second air inlet 113, the buffer groove 116 can release some of the return air channel, thereby further reducing the flow rate of the return air.

[0056] For further information, please refer to Figure 1 , the main body 110 is an elastic member; and / or,

[0057] An elastic sealing ring 111 is provided on the outer wall of the main body 110; and / or,

[0058] Along the length direction of the return air duct, the cross-sectional shape of the return air duct is an asymmetric shape, and the shape and size of the filter element 120 are adapted to the shape and size of the return air duct.

[0059] In this embodiment, when the main body 110 is an elastic member, it can be quickly fitted with the microphone 130 and the filter 120 through elastic deformation, thereby quickly achieving the installation of the microphone assembly 100 and improving the installation efficiency of the microphone assembly 100. The elastic sealing ring 111 on the outside of the main body 110 can seal the outer wall of the main body 110 when it needs to abut against an external device, thereby preventing external air from flowing into the first air inlet 112 through the gap between the outer wall and the external device. When the cross-sectional shape of the return air duct is an asymmetric shape, for example Figure 1 When the shape and size of the filter element 120 are adapted to the shape and size of the return air duct, it is possible to prevent the filter element 120 from being fooled during installation, thereby avoiding errors in the installation angle of the filter element 120 and improving the installation efficiency of the microphone assembly 100.

[0060] Please refer to Figure 2 and Figure 3 The present application also provides an atomizing device 10, which includes the microphone assembly 100 of any one of the above embodiments.

[0061] In this embodiment, since the atomizing device 10 includes the microphone assembly 100 of any one of the above embodiments, the return air duct can make the return gas flowing to the location of the microphone 130 flow according to a preset path, thereby preventing the return gas from being unable to converge after being dispersed and contacting the microphone 130 through the gaps of the remaining components; at the same time, since the filter element 120 is located between the microphone 130 and the first air inlet 112, the return gas will first contact the filter element 120 before contacting the microphone 130, thereby removing the liquid in the return gas and the atomized liquid and other liquids, thereby preventing the liquid from contaminating the surface of the microphone 130, thereby preventing the sensitivity of the microphone 130 from changing, thereby improving the stability and service life of the atomizing device 10 and the user experience.

[0062] For further information, please refer to Figure 2 and Figure 3 The atomizing device 10 further includes a housing 200 and a plurality of heating elements 520 . At least two suction air passages 510 are provided in the housing 200 . The suction air passages 510 are used to inhale aerosols.

[0063] At least two heating elements 520 are provided in a single suction airway 510 , and the heating elements 520 are used to heat the material to be heated to generate aerosol.

[0064] In this embodiment, since the housing 200 of the atomizing device 10 has two suction air passages 510, and at least two heating elements 520 are provided in each of the two suction air passages 510, when the microphone 130 senses the airflow and causes the heating elements 520 to heat the material to be heated, due to the large number of heating elements 520, it can heat the material to be heated to efficiently generate a large amount of aerosol, and the aerosol is heated more evenly, the particles are finer, and the taste is more integrated; the dual suction air passages 510 enable the user to inhale a large amount of aerosol at one time, thereby achieving a strong explosive suction taste. The gas flow path during inhalation through the suction air passage 510 is as follows: Figure 2 The second path 30 is shown by the dotted arrow in FIG.

[0065] For further information, please refer to Figure 2 and Figure 3 The atomizing device 10 further includes a fixing member 300, a battery 600, and a liquid storage tank 500. The fixing member 300 includes a first fixing plate 310 and a second fixing plate 320 that are perpendicular to each other and integrally formed. The first fixing plate 310 and the second fixing plate 320 together define an installation cavity. A placement groove 311 is provided on a side of the first fixing plate 310 facing the installation cavity.

[0066] The liquid storage tank 500 is in contact with the second fixing plate 320 and is located in the installation cavity. The battery 600 is installed in the placement groove 311 and is located between the liquid storage tank 500 and the battery 600 .

[0067] In this embodiment, because the first fixing plate 310 and the second fixing plate 320 of the fixing member 300 are integrally formed, modular installation is possible. Specifically, the liquid reservoir 500 can be first installed in the installation cavity, and then the battery 600 can be installed in the placement groove 311. Then, the fixing member 300 with the above components can be quickly installed in the housing 200 as an integral module. While assembling components such as the fixing member 300, battery 600, and liquid reservoir 500, the microphone assembly 100, PCB board 400, and other components can also be assembled with the housing 200, thereby improving the assembly efficiency of the atomizing device 10.

[0068] For further information, please refer to Figure 2 and Figure 3 The atomizing device 10 further includes a PCB board 400, which is located on a side of the first fixing plate 310 where the placement groove 311 is not provided. The microphone 130 is passed through the PCB board 400, and one end of the main body 110 abuts against the PCB board 400, and the other end abuts against the fixing member 300; and / or,

[0069] The atomizing device 10 further includes EVA cotton, which is located between the battery 600 and the bottom of the placement groove 311 .

[0070] In this embodiment, the microphone 130 is installed on the PCB board 400, and a USB is provided on the PCB board 400. The USB is installed on the housing 200 and can serve as the air inlet of the microphone 130. That is, when the user inhales the atomizing device 10, the gas flow path received by the microphone 130 is as follows: Figure 2 The middle arrow indicates the first path 20. At this time, the main body 110 is sleeved on the microphone 130, with one end abutting against the PCB board 400.

[0071] EVA cotton is an ethylene-vinyl acetate copolymer, which provides shock absorption and thermal insulation, preventing the battery 600 from overheating and causing the first fixing plate 310 to melt. It should be understood that the liquid storage tank 500 can be made of a thermally insulating material, so it is not easily affected by the high temperature of the battery 600, and the heat of the heating element 520 inside it is not easily transferred out of the liquid storage tank 500.
