Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices, also known as electronic cigarettes, are devices that heat and atomize e-liquid to create an aerosol for users to inhale, simulating the sensation of smoking. As a substitute for cigarettes, they are popular among smokers. Typically, an electronic atomizing device consists of a reservoir, an atomizing component, a power supply, and a control unit. The atomizing component contains an atomizing coil, and the e-liquid is stored in the reservoir. The control unit controls the power supply to the atomizing coil, which heats and atomizes the e-liquid in the reservoir to create an aerosol for the user to inhale.

[0003] Currently, most e-cigarette devices have a layout where the e-liquid reservoir is located at the top (closest to the mouthpiece), the atomizing component in the middle, and the power and control components at the bottom (farthest from the mouthpiece). E-liquid in the reservoir flows to the atomizing component under gravity, where it is heated and atomized into an aerosol for vaping. However, in this layout, due to gravity, e-liquid constantly seeps downwards. If the device's seal is poor, leakage is very likely. Even with a good seal, e-liquid can still seep through the sealing joints over time, leading to leakage. Leaks can cause the e-cigarette to malfunction and become unusable, and in severe cases, may even lead to safety accidents. Utility Model Content

[0004] Based on this, the purpose of this application is to provide an electronic atomizing device to solve the problem of leakage that easily occurs in existing electronic atomizing devices because the oil storage tank is located above the atomizing component, causing the e-liquid to seep downwards under the influence of gravity.

[0005] According to one aspect of this application, an electronic atomizing device is provided, comprising:

[0006] The outer casing has an air inlet and an air outlet;

[0007] An oil storage tank is located at the end of the outer shell away from the air outlet, and the oil storage tank is used to store the atomizing medium.

[0008] An atomizing component, comprising a heating element and an oil guiding element; the atomizing component is disposed between the oil storage tank and the air outlet;

[0009] A transmission component, comprising a first part and a second part, wherein the first part is enclosed within the atomizing assembly and the second part extends into the oil storage tank;

[0010] When the transmission element is located in the electronic atomizing device, the first part has a higher density than the second part.

[0011] In one embodiment, the first part and the second part are an integral structure.

[0012] In one embodiment, before the transmission element is installed in the electronic atomizing device, the density of the first portion is higher than the density of the second portion;

[0013] Alternatively, before the transmission element is installed in the electronic atomizing device, the density of the first portion is the same as the density of the second portion. The electronic atomizing device also includes an oil reservoir that wraps around the first portion. When the oil reservoir and the transmission element are installed in the electronic atomizing device, the oil reservoir squeezes the first portion so that the density of the first portion is higher than the density of the second portion.

[0014] The heating element includes a main heating part and a non-main heating part. The main heating part is disposed near the connection between the first part and the second part, and the non-main heating part is disposed away from the connection between the first part and the second part.

[0015] In one embodiment, the heating element further includes a heat-conducting portion, which is at least partially located in the first portion, and the heat-conducting portion is used to transfer a portion of the heat from the heating element to the first portion.

[0016] In one embodiment, an oil storage component is further included, which is wrapped around the first portion, wherein the oil storage component is made of the same material as the transmission component, and the oil storage component is made of a different material than the oil guide component.

[0017] In one embodiment, the oil storage tank further includes a sealing assembly having an oil guiding channel, and at least a portion of the second part is filled into the oil guiding channel.

[0018] In one embodiment, the sealing assembly includes a conduit forming the oil channel, one end of the conduit extending into the oil reservoir and disposed near the bottom wall of the oil reservoir, and at least a portion of the second part filling the conduit.

[0019] In one embodiment, the sealing assembly includes a sealing bracket that seals the oil reservoir. The sealing bracket has an annular flange on the side away from the oil reservoir, and the annular flange forms a groove in which condensation cotton is disposed.

[0020] In one embodiment, the side surface of the sealing assembly away from the oil storage tank forms a power supply mounting position with the inner wall of the housing, and a power supply assembly is provided in the power supply mounting position, which is electrically connected to the atomizing assembly.

[0021] The aforementioned electronic atomizing device places the e-liquid reservoir inside the outer casing at the end furthest from the air outlet, and positions the atomizing component between the reservoir and the outlet. A transmission component is also included; the first part of the transmission component encloses the atomizing component, and the second part extends into the reservoir. This results in a layout where the reservoir is located at the bottom of the outer casing, and the atomizing component is positioned above it. This allows the transmission component to guide the e-liquid upwards into the atomizing component. Compared to existing electronic atomizing devices where the atomizing component is below the reservoir, storing the e-liquid at the bottom of the casing, rather than above the atomizing component and power supply, prevents downward leakage due to gravity. This avoids e-liquid leakage caused by negative pressure, high temperature, or prolonged storage, thus improving the user experience. Furthermore, by making the density of the first part higher than the second part, it also promotes faster e-liquid transfer from the second part to the first part, thus solving the problem of dry burning of the atomizing component due to insufficient e-liquid supply.

[0038] One embodiment of this application provides an electronic atomizing device for heating an atomizing medium stored inside the device to form an aerosol for a user to inhale.

[0039] The structure of the electronic atomizing device in this application will be described below using an electronic cigarette as an example. This embodiment is only used as an example and does not limit the technical scope of this application. It can be understood that in other embodiments, the electronic atomizing device of this application is not limited to an electronic cigarette, but can also be any other electronic atomizing device that can atomize the atomizing medium into an aerosol, which is not limited here.

[0040] See Figures 1 to 4 , Figure 1 This paper shows a schematic diagram of the appearance of the electronic atomizing device 10 in one embodiment of the present application. Figure 2 A top view of the electronic atomizing device 10 is shown. Figure 3An explosion diagram of the electronic atomizing device 10 is shown. Figure 4 A cross-sectional view of the internal structure of the electronic atomizing device 10 is shown. An embodiment of the electronic atomizing device 10 provided in this application includes a housing 100, an oil reservoir 200, an atomizing component 300, a transmission component 400, and a power supply component 500. The housing 100 has an air inlet 101 and an air outlet 102. The oil reservoir 200 is located at the end of the housing 100 away from the air outlet 102. The atomizing component 300 is located between the oil reservoir 200 and the air outlet 102 (i.e., in…). Figure 4 The power supply component 500 is electrically connected to the atomizing component 300 and is located next to the atomizing component 300, also located above the oil storage chamber 201. The oil storage chamber 200 is used to store the atomizing medium; the atomizing component 300 is used to heat the atomizing medium so that the atomizing medium can be atomized to generate an aerosol for the user to inhale; the power supply component 500 is used to provide electrical energy to the atomizing component 300. Specifically, in this application, the atomizing medium can be e-liquid.

[0041] See Figure 1 and Figure 4 In the embodiment shown in the figure, one end of the outer shell 100 has a mouthpiece 103, an air outlet 102 is provided on the mouthpiece 103, and an air inlet 101 is provided on the side wall of the outer shell 100. When the user vapes, the e-liquid is introduced from the oil storage chamber 201 from bottom to top by the transmission member 400 into the atomizing assembly 300; the atomizing assembly 300 heats and atomizes the e-liquid delivered by the transmission member 400 to generate an aerosol, and the aerosol mixes with the outside air entering the atomizing channel 301 from the air inlet 101 and is discharged from the air outlet 102 through the atomizing channel 301 and inhaled by the user.

[0042] Thus, from Figure 4 As can be seen, the oil storage chamber 201 is designed at the bottom inside the outer shell 100, and the atomizing component 300 and the power supply component 500 are located above the oil storage chamber 201. This design can prevent e-liquid from leaking downwards to the atomizing component 300 or the atomizing component 500 under the action of gravity. Compared with the traditional electronic atomizing device 10, where the atomizing component 300 or the power supply component 500 is located below the oil storage chamber 201, this design can solve the problem of e-liquid leakage caused by various factors such as negative pressure, high temperature or long-term placement.

[0043] Please continue reading. Figure 4 In one specific embodiment, a sealing assembly 600 is provided inside the outer casing 100, and the oil storage chamber 201 is formed by the side surface of the sealing assembly 600 away from the vent 102 and the inner wall of the oil storage chamber 200. Figure 4In the embodiment shown, the sealing assembly 600 includes a sealing bracket 610 and a first sealing element 620. One side of the sealing bracket 610 is away from the air outlet 102 and blocks the oil storage tank 200, while the other side is close to the air outlet 102. This allows the side of the sealing bracket 610 away from the air outlet 102 to form an oil storage cavity 201 with the inner wall of the oil storage tank 200. An oil guiding channel 601 is provided inside the sealing assembly 600. A portion of the transmission member 400 fills the oil guiding channel 601, while another portion is exposed outside the oil guiding channel 601 and connected to the atomizing assembly 300.

[0044] Combined Figure 4 and Figure 5 As shown, the sealing assembly 600 has an annular flange 611 on the side near the air outlet 102 (i.e., the side away from the oil reservoir 201). The first sealing member 620 is connected to the annular flange 611, and the atomizing assembly 300 is inserted into the side of the first sealing member 620 away from the sealing bracket 610. The annular flange 611 forms a groove 612, and the first sealing member 620 and the groove wall of the groove 612 together form an air inlet chamber 602 that is isolated from the oil reservoir 201 and the oil guide channel 601. The air inlet chamber 602 connects to the air inlet 101 and the atomizing channel 301. Preferably, a condensation cotton 700 is provided at the bottom of the air inlet chamber 602.

[0045] As can be seen, by designing an annular flange 611 at the end where the sealing bracket 610 is connected to the first sealing element 620, the sealing bracket 610 and the first sealing element 620 can form an air intake chamber 602. This facilitates the installation of the condensing cotton 700, and the extra space in the groove 612 can also be used to collect the condensate dripping from the atomizing channel 301, so that the condensate can only be collected in the groove 612 and will not flow to other places.

[0046] Based on the above embodiments, the sealing bracket 610 has a hollow tubular conduit 613, an oil channel 601 passing through both ends of the conduit 613, one end of the conduit 613 extending into the air inlet chamber 602 and inserted into the first seal 620, and the other end of the conduit 613 extending into the oil storage chamber 201, preferably extending close to the bottom wall of the oil storage tank 200. Figure 4 and Figure 5In the embodiment described above, the conduit 613 and the sealing bracket 610, except for the conduit 613, are integrally formed. This increases the sealing performance of the oil reservoir 200, ensuring that the e-liquid in the oil reservoir 200 can only flow onto the transmission component 400 within the oil guiding channel 601. Of course, the remaining parts of the conduit 613 and the sealing bracket 610 can also be connected in other ways, which are not limited here. Through the above design, when the electronic atomizing device 10 is placed on its side or upside down (i.e., the air outlet 102 is facing down), the e-liquid can still be sealed in the oil reservoir 200 and will not flow back into the transmission component 400 and / or the atomizing assembly 300.

[0047] Furthermore, in one embodiment, the sealing assembly 600 further includes an inner shell 630 and a second sealing member 640. The inner shell 630 has openings at both ends, with the edge of one axial opening connected to the first sealing member 620 and the edge of the other axial opening connected to the second sealing member 640. The first sealing member 620 and the second sealing member 640 respectively close the openings at both ends of the inner shell 630, so that the inner shell 630, the first sealing member 620, and the second sealing member 640 form a closed sealing cavity 603. One end of the atomizing assembly 300 is connected to the first sealing member 620, and the other end is connected to the second sealing member 640. The portion of the transmission member 400 exposed in the oil guide channel 601 is accommodated in the sealing cavity 603. The outer wall of the inner shell 630, the inner wall of the outer shell 100, and a portion of the groove wall of the groove 612 in the sealing bracket 610 together form a power supply mounting position 104. The power supply assembly 500 is installed in the power supply mounting position 104, and the power supply mounting position 104 is isolated from the sealing cavity 603. In this way, the e-liquid exposed in the oil channel 601 of the transmission component 400 and the condensate generated after atomization can only be sealed in the sealing cavity 603, so they will not leak into the power installation position 104 and damage the power supply component 500, thereby avoiding short circuits and thus avoiding safety accidents.

[0048] Regarding the structure of the power supply component 500, the power supply component 500 includes a power supply and a PCB board electrically connected to the power supply, as well as a microphone electrically connected to the PCB board. Its specific structure and function can be referred to the existing technology, and will not be elaborated here.

[0049] See Figure 6 In the structure of the transmission element 400, the transmission element 400 includes a first part 410 and a second part 420 that are interconnected, combined with Figure 4 and Figure 6As shown, the second part 420 extends into the oil storage tank 200 and at least partially fills the conduit 613 (i.e., at least partially fills the oil guiding channel 601). The first part 410 is exposed outside the conduit 613, with one end connected to the second part 420 and the other end wrapped around the atomizing component 300. Visually, in the embodiment shown, the transmission component 400 is shaped like a "7," with the first part 410 formed by bending one end of the second part 420. In other embodiments, the transmission component 400 can also have a "1"-shaped structure, where the first part 410 tubularly wraps around the atomizing component 300, and the second part 420 is elongated; the specific shape is not limited.

[0050] In one optional embodiment, the overall material of the transmission component 400 is fiber cotton, that is, the first part 410 and the second part 420 are made of the same material and have the same density. Thus, from a microscopic perspective, the transmission component 400 is essentially a structure composed of multiple strip-shaped fibers extending along its own length direction, with tiny gaps between adjacent fibers. In this way, when e-liquid comes into contact with the transmission component 400, it can penetrate into these tiny gaps, thereby overcoming gravity and being gradually transported from bottom to top to the atomizing component 300.

[0051] As a preferred embodiment of this implementation, the first part 410 and the second part 420 are integrally connected. This is because if the first part 410 and the second part 420 are separate structures, even if they are in contact with each other, it will affect the smoothness and speed of e-liquid transmission, and it will be impossible to ensure that the e-liquid is replenished to the atomizing component 300 in time, which will easily lead to dry burning.

[0052] However, it should be noted that in the above embodiments, if the density of the first part 410 and the second part 420 is the same, although the e-liquid can be transferred to the atomizing component 300, experiments have shown that the transfer speed will be relatively slow and uneven. This may also lead to the e-liquid not being supplied to the atomizing component 300 in time, thus failing to meet the normal use of the atomizing component 300, and may even lead to dry burning.

[0053] Therefore, in order to completely solve the problem of e-liquid not being supplied to the atomizing component 300 in a timely manner, as a more preferred embodiment, the first part 410 and the second part 420 have different densities. Specifically, the density of the first part 410 is greater than that of the second part 420. Thus, the distribution of strip fibers in the first part 410 is more dense than that in the second part 420. Therefore, the first part 410 has more micro-gaps for e-liquid to penetrate, which can promote the faster delivery of e-liquid from the second part 420 to the first part 410, thereby solving the problem of dry burning of the atomizing component 300 due to insufficient e-liquid supply.

[0054] There are several different ways to make the density of the first part 410 greater than that of the second part 420. For example, as a first possible approach, before the transmission member 400 is installed in the electronic atomizing device 10, it can be integrally cut from a fiber material with multiple densities (or gradient densities), thereby giving the transmission member 400 a first part 410 and a second part 420 with different densities. As a second possible approach, before the transmission member 400 is installed in the electronic atomizing device 10, it can be integrally cut from a material of the same density to form a first part 410 and a second part 420 with the same density, but when assembling the transmission member 400 into the housing 100, the density of the first part 410 is increased by applying external pressure; for example, by combining... Figure 4 and Figure 7 As shown, the outer casing 100 contains an oil storage component 800 made of the same material as the transmission component 400. The oil storage component 800 encloses the first part 410. When the oil storage component 800 and the transmission component 400 are installed in the electronic atomizing device 10, the oil storage component 800 compresses the first part 410. This allows the oil storage component 800 to apply external pressure to the first part 410, making the density of the first part 410 higher than that of the second part 420, thereby facilitating the transmission of e-liquid. Of course, it is understood that, based on the first implementation (i.e., the transmission component 400 itself is made of materials with multiple densities or gradually varying densities), the oil storage component 800 can also enclose the first part 410 to make the density of the first part 410 even greater. Furthermore, other methods of applying external pressure can also be used to increase the density of the first part 410; none of the above are limited.

[0055] It should be noted that the function of the e-liquid reservoir 800 is not only to increase the density of the first part 410, but also to further prevent the atomizing component 300 from dry burning. Specifically, since the e-liquid reservoir 800 encloses the first part 410, when the electronic atomizer is idle, e-liquid can be transported to the e-liquid reservoir 800 through the transmission component 400, thus allowing it to store a portion of e-liquid. In this way, when the atomizing component 300 needs to use a large amount of e-liquid in a short period of time, the e-liquid stored in the e-liquid reservoir 800 can be replenished to the atomizing component 300 in a timely manner, thereby further preventing dry burning.

[0056] Please continue reading. Figure 7 and Figure 8In one embodiment, the atomizing assembly 300 includes an atomizing tube 310, an oil guide 320, and a heating element 330. The atomizing tube 310 is also a hollow tubular structure. An atomizing channel 301 passes through the two opposite ends of the atomizing tube 310 along its own axial direction. One end of the atomizing tube 310 is connected to a first sealing element 620, and the other end is connected to a second sealing element 640. The first portion 410 of the transmission element 400 covers at least a portion of the outer peripheral surface of the atomizing tube 310. The oil guide 320 is also tubular and attached to the wall of the atomizing tube 310. The oil guide 320 is also connected to the first portion 410 of the transmission element 400. The heating element 330 is connected to the oil guide 320 and electrically connected to the power supply assembly 500. The oil guide 320 is made of a different material than the oil reservoir 800 (i.e., also different from the material of the transmission element 400), thereby facilitating oil locking and guiding.

[0057] Thus, the transmission component 400 can deliver e-liquid to the wicking component 320, which then temporarily stores the e-liquid and delivers it to the heating component 330. When the power supply component 500 is powered on, the heating component 330 generates heat under the power provided by the power supply component 500, thereby heating and atomizing the e-liquid in the wicking component 320 to generate an aerosol.

[0058] Furthermore, in a preferred embodiment, the heating element 330 includes a main heating part and a non-main heating part. The main heating part faces the connection position between the first part 410 and the second part 420 of the transmission element 400, while the non-main heating part faces away from the connection position between the first part 410 and the second part 420. The purpose of this arrangement is that, when the heating element 330 is working, it can transfer a portion of the heat to the first part 410 and the connection position between the first part 410 and the second part 420, thereby creating a significant temperature difference between the first part 410 and the second part 420. That is, the temperature at the first part 410 is significantly higher than the temperature at the end of the second part 420 that extends into the oil storage tank 200, thereby further accelerating the transfer speed of e-liquid from the oil storage tank 200 to the first part 410.

[0059] Specifically, in this embodiment, the transmission component 400 is shaped like a "7", and the heating component 330 is a curved mesh structure, such as a "C" shape. The opening of the "C" shape is the non-main heating part, and the remaining mesh part is the main heating part. During assembly, the opening of the "C" shape (non-main heating part) should be far away from the first part 410 of the transmission component 400, and the remaining mesh part (main heating part) should be close to the first part 410. This way, the main heating part can face the connection position between the first part 410 and the second part 420 of the transmission component 400, while the non-main heating part is away from the connection position between the first part 410 and the second part 420, thereby achieving the purpose of accelerating the transmission of e-liquid.

[0060] Furthermore, in order to accelerate the heat transfer of the heating element 330 to the first part 410, the heating element 330 also includes a heat-conducting part (not shown in the figure), which is at least partially located in the first part 410 and is used to transfer part of the heat of the heating element 330 to the first part 410.

[0061] It should be noted that the structure of the electronic atomizing device 10 provided in this application is not limited to the structure shown in the embodiment in the figure, and can also be other structures. For example, in other embodiments, the oil storage tank 200 can be externally connected to the outer shell 100 or internally installed in the outer shell 100; the power supply component 500 can be set outside the outer shell 100, or even the power supply component 500 can be not set inside the outer shell 100, and the atomizing component 300 can be powered by an external power source. It can be set as needed, and there is no limitation here.

[0062] Therefore, the electronic atomizing device 10 provided in this application, on the one hand, avoids leakage problems caused by various factors such as negative pressure, high temperature, and long-term placement by placing the oil storage chamber 200 at the bottom and transferring the e-liquid to the atomizing component 300 through the transmission component 400. Furthermore, with the structure of the conduit 613 extending into the oil storage chamber 201, the electronic atomizing device 10 will not leak even if placed on its side or upside down for a long time, thus effectively solving the industry pain point of oil leakage. On the other hand, the transmission component 400 is designed with a structure including a first part 410 and a second part 420 of different densities, which can accelerate the delivery of e-liquid from the oil storage chamber 201 to the atomizing component 300, enabling the transmission component 400 to supply e-liquid to the atomizing component 300 in a timely manner, meeting the usage needs of the atomizing component 300, effectively preventing dry burning, and thus greatly improving the user experience.

[0063] 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.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
