Description

Technical Field

[0001] This invention relates to the field of aerosol generation device technology, and more particularly to an atomizing component and atomizing device. Background Technology

[0002] An atomizer is an electronic device that mimics the function of a traditional cigarette. Its aerosol generation mechanism primarily involves a battery-powered heating coil that atomizes the aerosol matrix. Compared to traditional cigarettes, atomizers can be used for extended periods because the aerosol matrix and battery can be replaced to maintain their battery life.

[0003] To ensure the continuous permeation of the aerosol matrix stored in the fuel tank to the heating wire, the fuel tank is typically connected to the ventilation channel of the atomizer. However, existing atomizers lack additional space in their ventilation channels to store condensate. The condensate formed in the ventilation channel by the aerosol generated by the heating wire can easily clog the ventilation channel, thus affecting the permeation of the aerosol matrix from the fuel tank and reducing atomization efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an atomizing component and atomizing device to address the problem that existing atomizers do not have additional space for storing condensate in their ventilation channels, which can easily clog the ventilation channels, thereby affecting the penetration of the aerosol matrix in the oil tank and reducing atomization efficiency.

[0005] This invention provides an atomizing component, comprising:

[0006] The shell structure includes an oil reservoir, a ventilation channel, and an atomization channel. The oil reservoir is used to store the aerosol matrix. Both ends of the atomization channel are connected to the outside air. One end of the ventilation channel is connected to the atomization channel, and the other end of the ventilation channel can be connected to the oil reservoir to relieve pressure on the oil reservoir. The shell structure also has a storage cavity formed in the inner wall of the ventilation channel for storing condensate formed by aerosol liquefaction.

[0007] A heating structure is provided in the atomization channel, which can heat the aerosol matrix permeating the oil tank to form an aerosol.

[0008] The aforementioned atomizing component includes an oil tank that holds the aerosol matrix. The aerosol matrix in the oil tank can permeate to the heating structure, allowing the heating structure to heat and atomize the aerosol matrix into an aerosol. The user can draw air from one end of the housing structure into the atomization channel to extract the aerosol from the channel. As the aerosol matrix in the oil tank decreases, the negative pressure within the oil tank gradually increases. The oil tank can then be connected to external air through a ventilation channel to release pressure. Furthermore, a storage cavity is provided on the inner wall of the ventilation channel. The condensate formed by the liquefaction of the aerosol in the ventilation channel can flow into the storage cavity for collection, thus preventing condensate blockage of the ventilation channel and ensuring that the oil tank can release pressure through the ventilation channel.

[0009] In one embodiment, the housing structure includes a connected outer shell and a flow guide, the flow guide being located inside the outer shell, the oil tank being disposed inside the outer shell, and the flow guide having a flow channel connecting the oil tank and the heating structure, so that the aerosol matrix of the oil tank can flow to the heating structure through the flow channel.

[0010] In one embodiment, the flow channel has a flow ramp that is inclined relative to the extension direction of the outer casing, with the lower end of the flow ramp close to the heating structure and the higher end of the flow ramp close to the oil tank.

[0011] In one embodiment, the outer wall of the flow guide is provided with a pressure relief channel, a vent, and the storage cavity. The storage cavity is located on the side wall of the pressure relief channel. The flow guide is provided with a ventilation cavity. One end of the pressure relief channel is connected to the oil tank, and the other end is connected to the ventilation cavity through the vent. The ventilation cavity is connected to the atomization channel and the outside air. The pressure relief channel, the vent, and the ventilation cavity form part of the ventilation channel.

[0012] In one embodiment, there are multiple storage cavities, which are spaced apart along the extension direction of the pressure relief channel.

[0013] In one embodiment, the housing structure further includes a base having a plurality of spaced and interconnected pressure balancing slots, all of which are connected to the ventilation chamber and the atomization channel. The pressure balancing slots are capable of storing condensate formed by aerosol liquefaction.

[0014] In one embodiment, the housing structure further includes an intermediate component located between the base and the flow guide. The intermediate component has a central hole that connects the ventilation chamber and the pressure balance groove. The intermediate component has a receiving groove on the side facing the base that is located outside the pressure balance groove and the pressure balance groove connects the central hole and the atomization channel.

[0015] In one embodiment, the oil tank is provided with a one-way valve, the oil tank has an opening, and the one-way valve can rotate relative to the oil tank to open or close the opening of the oil tank; the aerosol matrix in the oil tank can permeate into the heating structure to create a negative pressure in the oil tank, thereby driving the one-way valve to open the opening of the oil tank, and the interior of the oil tank is connected to the ventilation channel to release pressure.

[0016] In one embodiment, the heating structure includes a heating element, an electrode rod, and an elastic pad. One end of the electrode rod is connected to the heating element, and the other end of the electrode rod is used to connect to a power source to supply power to the heating element, thereby driving the heating element to heat and atomize the aerosol matrix into an aerosol. The electrode rod, in conjunction with the elastic pad, clamps and fixes the heating element.

[0017] The present invention also provides an atomizing device, including a power supply component and the aforementioned atomizing component. The power supply component is detachably connected to the housing structure. When the power supply component is connected to the housing structure, the power supply component is electrically connected to the heating structure and can supply power to the heating structure to drive the heating structure to heat the atomized aerosol matrix.

Obviously, the specific details described below are only a part of the embodiments of the present invention, and the present invention can be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] The present invention provides an atomizing device that can store a certain amount of liquid aerosol matrix and heat and atomize the aerosol matrix into aerosol for users to inhale.

[0042] The atomizing device includes an atomizing component 100 and a power supply component connected together. The power supply component and the atomizing component can be fixedly connected or detachably connected by magnetic attraction, snap-fit, or other means, which is not limited here. The power supply component contains a battery. When the power supply component is connected to the atomizing component 100, the power supply component can supply power to the atomizing component 100, so that the atomizing component 100 can heat and atomize the stored aerosol matrix into an aerosol.

[0043] refer to Figure 1 , Figure 2 and Figure 3 The atomizing component 100 includes a housing structure 101 and a heating structure 102, with the heating structure 102 disposed inside the housing structure 101. The housing structure 101 is used to store the aerosol matrix, and the heating structure 102 is used to heat and atomize the aerosol matrix into an aerosol.

[0044] refer to Figure 3 The housing structure 101 includes an outer shell 1, a package 2, a flow guide 3, an intermediate component 4, a base 5, and a bottom shell 6. The package 2 is sleeved on the flow guide 3, the flow guide 3 is connected to the intermediate component 4, the intermediate component 4 is connected to the base 5, the base 5 is connected to the bottom shell 6, and the bottom shell 6 is detachably connected to the outer shell 1 to encapsulate the package 2, the flow guide 3, the intermediate component 4, and the base 5 inside the outer shell 1.

[0045] The end of the outer shell 1 away from the bottom shell 6 is a suction nozzle 11, which is duckbill-shaped to facilitate suction by the user's mouth. It is understood that in other embodiments, the suction nozzle 11 may also be other shapes, such as cylindrical or elliptical cylindrical shapes, which are not limited here.

[0046] The outer casing 1 has first snap-fit ​​flanges 12 on both sides of its end near the bottom casing 6. The first snap-fit ​​flanges 12 are used to snap into the bottom casing 6 to connect the outer casing 1 to the bottom casing 6. It is understood that in other embodiments, the outer casing 1 can also be detachably connected to the bottom casing 6 in other ways, such as magnetic connection or screw connection, etc., which are not limited here.

[0047] The outer casing 1 contains an oil reservoir 13 for storing the aerosol matrix. Additionally, the oil reservoir 13 is connected to a heating structure 102, enabling the heating structure 102 to heat and atomize the aerosol matrix into an aerosol.

[0048] The outer casing 1 is provided with a ventilation column 14, and the ventilation column 14 has an exhaust channel 141. The exhaust channel 141 passes through both ends of the ventilation column 14 and is located near the central axis of the outer casing 1. The exhaust channel 141 connects the heating structure 102 and the outside of the outer casing 1, so that the aerosol generated by the heating structure 102 can flow out to the outside of the outer casing 1 through the exhaust channel 141 for the user to inhale.

[0049] refer to Figure 4 The encapsulation component 2 is provided with a first sealing ring 21 and a second sealing ring 22 along its periphery, with the first sealing ring 21 and the second sealing ring 22 spaced vertically apart. The first sealing ring 21 and the second sealing ring 22 abut against the inner wall of the oil tank 13 to seal the inner wall of the oil tank 13 and prevent the aerosol matrix of the oil tank 13 from flowing out from its inner wall. It can be understood that in other embodiments, the number of sealing rings can be three or more, so as to improve the sealing effect on the inner wall of the oil tank 13.

[0050] The package 2 is hollow, meaning it has a first receiving cavity 23 inside. The package 2 is made of silicone, which gives it good elasticity and sealing ability. When the package 2 is fitted onto the flow guide 3, the flow guide 3 is located in the first receiving cavity 23 of the package 2.

[0051] The encapsulation component 2 has a liquid outlet 24 and a first through hole 25. The liquid outlet 24 connects the first accommodating cavity 23 and the oil tank 13, allowing the aerosol matrix in the oil tank 13 to flow into the first accommodating cavity 23 through the liquid outlet 24. There are two liquid outlets 24, located on both sides of the first through hole 25. It is understood that in other embodiments, one, three, or more liquid outlets 24 may be provided, which is not limited here.

[0052] The first through hole 25 is sealed and inserted into the vent column 14. Figure 2 (As shown), to prevent leakage of the aerosol matrix within the oil tank 13. The venting column 14 has an outlet channel 141 connected to the first receiving cavity 23.

[0053] refer to Figure 5 and Figure 6The guide member 3 has a second through hole 31, which is hollow with openings at both ends. The two ends of the second through hole 31 are connected to the first through hole 25 and the heating structure 102, respectively. The aerosol generated by the heating structure 102 can flow into the gas outlet channel 141 through the second through hole 31 and the first through hole 25 in sequence.

[0054] The guide member 3 has a guide channel 32, with both ends of the guide channel 32 passing through it. One end of the guide channel 32 is connected to the liquid outlet 24, and the other end is connected to the heating structure 102. Therefore, the oil tank 13 is sequentially connected to the liquid outlet 24, the guide channel 32, and the heating structure 102. The aerosol matrix in the oil tank 13 can flow sequentially through the liquid outlet 24 and the guide channel 32 to the heating structure 102, so that the heating structure 102 can heat and atomize the flowing aerosol matrix into aerosol.

[0055] The inner wall of the flow guiding channel 32 is partially inclined, forming a flow guiding slope 321. The lower end of the flow guiding slope 321 is closer to the heating structure 102, so that the aerosol matrix can flow more easily to the heating structure 102 through the guiding effect of the flow guiding slope 321. There are two flow guiding channels 32, located on both sides of the second through hole 31. In other embodiments, one, three, or more flow guiding channels 32 may be provided, which is not limited here.

[0056] The outer wall of the flow guide 3 has four air passage units 33, with two air passage units 33 provided on each side of the flow guide 3. It is understood that in other embodiments, the number of air passage units 33 provided on the flow guide 3 may be one, two, three, five or more, and is not limited here.

[0057] Each air duct unit 33 is connected to the oil tank 13 and the heating structure 102. Since the heating structure 102 is connected to the air outside the outer shell 1 through the second through hole 31, the first through hole 25, and the air outlet channel 141, the air duct unit 33 is connected to the air outside the outer shell 1, that is, the oil tank 13 is connected to the outside air through the air duct unit 33. As the heating structure 102 heats and atomizes the aerosol matrix, the aerosol matrix in the oil tank 13 gradually decreases, and the negative pressure formed in the oil tank 13 can be released sequentially through the air duct unit 33 so that the aerosol matrix in the oil tank 13 can continue to flow to the heating structure 102 by its own gravity.

[0058] In addition, the air passage unit 33 can also store a certain amount of liquid. When the aerosol generated by the heating structure 102 flows to the air passage unit 33 and liquefies to form condensate, the condensate can be stored in the air passage unit 33. At the same time, the air passage unit 33 can still continue to connect the oil tank 13 and the outside air, and the oil tank 13 can continue to depressurize.

[0059] The air duct unit 33 includes a pressure relief channel 331 and a first storage cavity 332, a second storage cavity 333, a third storage cavity 334, and a vent 335 that connect to the pressure relief channel 331. The pressure relief channel 331 connects to the oil tank 13 and the vent 335, and the vent 335 connects to external air, allowing the oil tank 13 to release pressure. The first storage cavity 332, the second storage cavity 333, and the third storage cavity 334 are arranged vertically at intervals, and the condensate formed after the aerosol liquefies in the pressure relief channel 331 can be stored in the first storage cavity 332, the second storage cavity 333, and the third storage cavity 334. Since the first storage cavity 332, the second storage cavity 333, and the third storage cavity 334 are not on the extension path of the pressure relief channel 331, even if multiple storage cavities store condensate, it will not block the pressure relief channel 331, and the oil tank 13 can still communicate with the external air. It should be emphasized that the number of the above-mentioned storage cavities is not limited, and one, two, four, or more can be set, which is not limited here.

[0060] A ventilation chamber 34 is provided on one side of the flow guide 3 opposite to the flow guide channel 32. The ventilation chamber 34 is connected to the air inlet 335 and the outside air.

[0061] The guide member 3 also has a second snap-fit ​​flange 35 on both sides, which is used to detachably snap-fit ​​with the base 5.

[0062] refer to Figure 7 and Figure 8 An airflow hole 41 is provided in the middle part of the intermediate part 4. The airflow hole 41 extends through the thickness direction of the intermediate part 4, allowing external air to flow into the intermediate part 4.

[0063] An airflow groove 42 is provided around the airflow hole 41 in the middle part of the intermediate component 4. External air can flow into the airflow groove 42 through the airflow hole 41 and then flow from the airflow groove 42 to the heating structure 102 to carry out the aerosol generated by the heating structure 102.

[0064] The bottom of the airflow channel 42 has two first mounting holes 43, which penetrate the intermediate part 4 and are used to supply two electrode rods 9 respectively. Figure 3 (As shown) The two electrode rods 9 are fixed in place, one positive and one negative. One end of each electrode rod 9 is electrically connected to the heating structure 102, and the other end is exposed to the outside for connecting to the battery in the power supply assembly. Thus, the battery supplies power to the heating structure 102 through the two electrode rods 9, causing the heating structure 102 to heat up.

[0065] The intermediate component 4 has a central hole 44 at both its left and right ends, through which the central hole 44 passes. The central hole 44 connects the ventilation chamber 34 and the base 5.

[0066] The intermediate part 4 has a receiving groove 45 on the side opposite to the airflow groove 42. The receiving groove 45 can be used to receive a part of the electrode rod, which facilitates the positioning and installation of the electrode rod, and also provides more space for airflow.

[0067] refer to Figure 9 The base 5 has first locking holes 51 on both sides, and the first locking holes 51 can be detachably locked to the second locking flange 35 of the guide 3.

[0068] The base 5 also has two first pressure balancing grooves 52 and two second pressure balancing grooves 53. The two first pressure balancing grooves 52 are located on the left and right sides of the base 5, respectively, and the two second pressure balancing grooves 53 are also located on the left and right sides of the base 5, respectively. The first pressure balancing grooves 52 and the second pressure balancing grooves 53 on the same side of the base 5 are spaced apart and interconnected. When the base 5 and the guide member 3 are engaged, the base 5 and the guide member 3 can clamp and fix the intermediate member 4 in the middle, and the first pressure balancing groove 52 connects to the intermediate hole 44.

[0069] The base 5 also has nine air inlets 54 arranged in an array. It is understood that the number of air inlets 54 can also be other, and the arrangement can be in other ways, such as a circular array, which is not limited here.

[0070] The air inlet 54 penetrates the base 5 and is connected to the second air pressure balance groove 53. Therefore, the oil tank 13 can sequentially pass through the pressure relief channel 331, the air vent 335, the air exchange chamber 34, the intermediate hole 44, the first air pressure balance groove 52, the second air pressure balance groove 53, and the air inlet 54 to connect with the outside air, thereby achieving pressure relief. The aerosol matrix in the oil tank 13 can flow smoothly to the heating structure 102 by its own gravity.

[0071] It should be emphasized that the receiving groove 45 of the intermediate component 4 is a certain distance from the top of the first pressure balancing groove 52 and the second pressure balancing groove 53, and the intermediate hole 44 and the air inlet 54 are both connected to the receiving groove 45. Therefore, even if the first pressure balancing groove 52 and the second pressure balancing groove 53 are filled with condensate, it will not block the connection between the intermediate hole 44 and the outside air, thus not affecting the connection between the oil tank 13 and the outside air.

[0072] The base 5 also has two second mounting holes 55, which are respectively connected to two first mounting holes 43. One end of each of the two electrode rods 9 can pass through the first mounting holes 43 and the second mounting holes 55 in sequence and be exposed to the outside. When the power supply component is connected to the atomizing component 100, the two electrode rods 9 are electrically connected to the battery of the power supply component.

[0073] The base 5 has a mounting groove 56 along its periphery, and a sealing ring 57 is fitted into the mounting groove 56. The sealing ring 57 is made of silicone and is used to abut against the inner wall of the base shell 6 to prevent air leakage inside the base 5.

[0074] refer to Figure 3 The bottom shell 6 has a second receiving cavity 61, which is closed at one end and open at the other end. The second receiving cavity 61 is used to accommodate the base 5, and the sealing ring 57 on the base 5 is tightly attached to the cavity wall of the second receiving cavity 61 to ensure the sealing of the base 5.

[0075] The bottom shell 6 has second locking holes 62 on both sides. The second locking holes 62 are used to engage with the first locking flange 12 of the outer shell 1 to encapsulate multiple other components.

[0076] refer to Figure 2 and Figure 3 The heating structure 102 includes a heating element 7, a gasket 8, and the two electrode rods 9 mentioned above. The heating element 7 is disposed between the gasket 8 and the two electrode rods 9. One end of each electrode rod 9 is connected to the positive and negative terminals of the heating element 7, respectively. The gasket 8 is made of silicone, but other elastic materials can also be used. Both ends of the gasket 8 abut against the flanges of the heating element 7 and the flow guide 3, respectively, to prevent the heating element 7 from directly contacting the flow guide 3.

[0077] A third through hole 81 is provided in the middle part of the gasket 8. The third through hole 81 connects the heating body 7 and the flow channel 32 of the flow guide 3, so that the aerosol matrix can flow to the heating body 7 through the third through hole 31. Then, after the heating body 7 is powered on, it can heat and atomize the aerosol matrix into aerosol.

[0078] A positioning protrusion 91 is provided along the periphery of the middle part of the electrode rod 9. Figure 3 As shown, the positioning protrusion 91 is engaged in the receiving groove 45 of the intermediate part 4, and the intermediate part 4, together with the base 5, clamps the positioning protrusion 91, thereby positioning the electrode rod 9. When the electrode rod 9 is fixed, the electrode rod 9, together with the gasket 8, clamps and fixes the heating element 7.

[0079] refer to Figure 10 It should be emphasized that there is a certain gap between the heating element 7 and the inner wall of the guide member 3, which connects the airflow hole 41 and the air outlet channel 141. The aerosol generated by the heating element 7 can flow out from the air outlet channel 141.

[0080] refer to Figure 11 , Figure 11A schematic diagram of the air passage of the present invention is shown. It is worth noting that the aforementioned air inlet 54, airflow hole 41, airflow groove 42, second through hole 31, and air outlet channel 141 together constitute the atomizing channel 15. It can be understood that the length extension direction of the atomizing channel 15 is parallel to the length extension direction of the outer shell 1, and both ends of the atomizing channel are connected to the external air of the outer shell 1. When the user inhales through the mouthpiece 11, external air can enter the atomizing channel through the air inlet 54. After the airflow mixes with the aerosol generated by the heating element 7, it enters the user's mouth through the air outlet channel 141.

[0081] The second pressure balance groove 53, the first pressure balance groove 52, the intermediate hole 44, the air exchange chamber 34, the vent 335, and the pressure relief channel 331 form the air exchange channel 16. It can be understood that one end of the air exchange channel 16 is connected to the oil tank 13, and the other end is connected to the atomization channel 15. Since the atomization channel 15 is connected to the outside air, the air exchange channel 16 is connected to the outside air, and the oil tank 13 is depressurized.

[0082] The flow guide 3 also includes a one-way valve 36, one end of which is rotatably connected to the side wall of the flow guide 3. The free end of the one-way valve 36 can only rotate toward the inside of the oil tank 13. A torsion spring (not shown in the figure) can be installed at the rotatable connection position of the one-way valve 36. In its natural state, the torsion spring can drive the one-way valve 36 to close the outlet of the oil tank 13 through its elastic force.

[0083] When the user inhales through the nozzle 11, the atomization channel 15 is under negative pressure. Since the atomization channel 15 connects to the ventilation channel 16, the ventilation channel 16 is also under negative pressure. Because the one-way valve 36 cannot rotate outwards from the oil tank 13, the outlet of the oil tank 13 remains closed. The heating element 7 can be made of ceramic material, which has natural pores. Furthermore, the heating element 7 connects to the oil tank 13, and the atomization channel 15 can exert a certain suction force on the oil tank 13 through the pores of the heating element 7. Combined with the gravity of the aerosol matrix 10 itself, this allows more of the aerosol matrix 10 to flow towards the heating element 7 and be atomized into an aerosol.

[0084] As the aerosol matrix in oil tank 13 gradually decreases, the negative pressure in oil tank 13 gradually increases until it drives the one-way valve 36 to overcome the elastic force of the torsion spring and rotate towards the inside of oil tank 13, so that oil tank 13 is connected to ventilation channel 16. Air from ventilation channel 16 enters oil tank 13, relieving pressure in oil tank 13. The negative pressure in oil tank 13 gradually decreases until it tends to balance, so that the aerosol matrix 10 in oil tank 13 can continue to flow into heating element 7 by its own gravity.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0086] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent.
