Description

Technical Field

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

[0002] Electronic atomizing devices (such as electronic cigarettes) are electronic devices that atomize liquids into tiny particles. The core principle of these devices is to use internal atomizing components to heat the liquid to a sufficient temperature through resistance heating, thereby atomizing the liquid.

[0003] In related technologies, the atomizing core in the atomizing component of an electronic cigarette typically includes a substrate (such as porous ceramic) and a heating element (such as an electric heating wire). The heating element needs to be electrically connected to a power source via an electrical connector. During use, incompletely atomized e-liquid flows downwards along the electrical connector, resulting in e-liquid waste and a reduction in the number of puffs the user can take. Furthermore, even after the user stops vaping continuously, the heating element still retains a high residual temperature, and the substrate continues to release e-liquid for a period of time. Therefore, it often happens that during storage, the seeping e-liquid clogs the air vents, causing the user to find increased draw resistance when using it again, thus affecting the user's vaping experience. Summary of the Invention

[0004] In view of this, this application provides an atomizing component that, by incorporating a heating element and a liquid-absorbing structure, can effectively seal the leakage and blockage pores of the atomizing core.

[0009] A heating element, connected to the absorbent liquid, and used to atomize the liquid in the absorbent liquid; and,

[0010] An electrical connector is provided to be electrically connected to the atomizing core and the heating element to form a heating circuit. The heating circuit is configured to operate in a single-mode where only the atomizing core operates when the temperature of the atomizing core is less than a first threshold temperature, and in a multi-mode where the atomizing core and the heating element operate simultaneously when the temperature of the atomizing core is greater than the first threshold temperature but less than a second threshold temperature.

[0011] Optionally, the heating element is electrically connected to both the atomizing core and the electrical connector;

[0012] When the temperature of the atomizing core is lower than the first threshold temperature, the electrical connector is electrically connected to the atomizing core to short-circuit the heating element. When the temperature of the atomizing core is greater than the first threshold temperature but less than the second threshold temperature, the electrical connection between the electrical connector and the atomizing core is disconnected to connect the heating element and the atomizing core in series.

[0013] Optionally, the electrical connector is an electrode sheet, and the electrode sheet has an electrical connection portion that can be electrically connected to the atomizing core, the electrical connection portion being made of a thermo-deformable metal material.

[0014] Optionally, the electrical connection portion is a bimetallic strip, and when the temperature of the atomizing core is greater than the first threshold temperature but less than the second threshold temperature, the bimetallic strip bends in a direction away from the atomizing core to disconnect the electrical connection between the electrical connection portion and the atomizing core.

[0015] Optionally, the heating element includes:

[0016] The first contact piece is electrically connected to the electrical connector.

[0017] The second contact is electrically connected to the atomizing core.

[0018] The heating element is disposed between the first contact piece and the second contact piece. The liquid absorber is disposed on the side of the heating element away from the atomizing core. The heating element is provided with a channel that allows the liquid leakage from the atomizing core to flow to the liquid absorber.

[0019] Optionally, the heating power of the heating element accounts for 20%-30% of the total heating power of the atomizing assembly.

[0020] Optionally, the electrode sheet includes a positive electrode sheet and a negative electrode sheet;

[0021] The heating element includes a first heating element and a second heating element, wherein the first heating element is electrically connected to the positive electrode plate and the atomizing core, and the second heating element is electrically connected to the negative electrode plate and the atomizing core.

[0022] Optionally, the range of the first threshold temperature is 220℃-260℃.

[0023] Optionally, the electrical connection portion of the positive electrode and the electrical connection portion of the negative electrode are configured to disconnect from the atomizing core at different temperatures.

[0024] Optionally, when the electrical connection between one of the electrical connection portions of the positive electrode plate and the negative electrode plate is disconnected from the atomizing core, the temperature of the atomizing core is within the range of 180℃-220℃; when the electrical connection between the other and the atomizing core is disconnected, the temperature of the atomizing core exceeds 220℃.

[0025] Optionally, the resistance values ​​of both the first contact and the second contact are less than the resistance value of the heating element.

[0026] Optionally, when the temperature of the atomizing core is greater than the second threshold temperature, the heating circuit is configured to be in open circuit mode.

[0028] The leakage generated by the atomizing core in the atomizing assembly provided in this application is absorbed by the absorbed liquid. Furthermore, during operation, when the temperature of the atomizing core is below a first threshold temperature, only the atomizing core operates in the heating circuit of the atomizing assembly. When the temperature of the atomizing core exceeds the first threshold temperature, both the atomizing core and the heating element operate simultaneously in the heating circuit. During operation, the heating element atomizes the liquid in the absorbed liquid, effectively preventing the leakage generated by the atomizing core from accumulating to supersaturation in the absorbed liquid. This ensures that the leakage generated by the atomizing core does not stagnate in the gas flow channel, thus guaranteeing unobstructed gas flow. Simultaneously, the atomization of the absorbed liquid by the heating element also enables liquid recycling and reuse. Moreover, in the above process, the heating element in the atomizing assembly uses the temperature of the atomizing core as the basis for activation. Specifically, the heating element activates when the temperature of the atomizing core reaches the first threshold temperature and does not activate when the temperature of the atomizing core is below the first threshold temperature, thereby achieving automated heating element control and improving the user experience.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0043] First, it should be noted that the atomizing component in this application embodiment is suitable for scenarios where liquid is converted into tiny mist particles by heating; for example, in the field of electronic cigarettes, e-liquid is atomized by heating to form smoke, and in the medical field, some medical atomizers heat drugs to make them evaporate and produce tiny drug particles.

[0044] like Figures 1-6 As shown, the atomizing component provided in this embodiment includes an atomizing core 1, a liquid absorber 3, an electrical connector, and a heating element 2, wherein...

[0045] The atomizing core 1 is a structure in the atomizing assembly that uses resistance heating to atomize liquid. In an exemplary embodiment, the atomizing core 1 includes a substrate and a heating element. The substrate can be a porous liquid-conducting material, such as porous ceramic or porous glass, or a porous liquid-conducting material formed by opening liquid-conducting holes in dense ceramic or dense glass. The heating element can be a metal sheet, metal mesh, metal wire, or metal coating disposed on the substrate. Of course, in some other embodiments, the atomizing core 1 can also be composed of oil-conducting cotton and a metal sheet. During operation, the liquid in the liquid storage structure (such as the oil cup mentioned below) flows into the substrate of the atomizing core 1. The heating element in the atomizing core 1 is heated by electricity and heats the liquid in the substrate to atomize it.

[0046] The liquid absorber 3 is a structure used to absorb and constrain the flow of liquid. It can absorb and store the leakage from the atomizing core 1, thereby preventing the leakage from the atomizing core 1 from remaining in the gas flow channel 19 (i.e., the channel used to guide the liquid to the target area after atomization), and thus preventing the leakage from the atomizing core 1 from clogging the gas flow channel 19. In an exemplary embodiment, the liquid 3 can be made of oil-absorbing cotton, organic cotton, or fiber cotton, etc.

[0047] The heating element 2 is a structural component in the atomization assembly that can convert electrical energy into heat energy. In specific implementation, the heating element 2 can be a metal sheet, metal mesh, or metal wire with a certain resistance value. The heating element 2 is connected to the liquid absorber 3 and can atomize the liquid in the liquid absorber 3.

[0048] Electrical connectors are structural components in the atomizing assembly that electrically connect the atomizing structure (i.e., the atomizing core 1 and heating element 2 mentioned above) to a power source (such as the battery cell 10 mentioned below) to form a heating circuit. In specific implementations, electrical connectors can be wires, or they can be... Figures 1-6 Electrode 4 in the middle.

[0049] Furthermore, the aforementioned heating circuit is configured to operate in a single-emission mode (where only the heating element in the atomizing core 1 heats the liquid to atomize it) when the temperature of the atomizing core 1 is below a first threshold temperature, and in a multi-emission mode (where both the atomizing core 1 and the heating element 2 heat the liquid to atomize it) when the temperature of the atomizing core 1 is above the first threshold temperature but below a second threshold temperature, operating simultaneously. Thus, during operation, any leakage from the liquid inhaled into the atomizing component 3 can be atomized promptly by the heating element 2. This effectively prevents the leakage from the atomizing core 1 from accumulating to oversaturation in the liquid inhaled into ... Furthermore, in the above process, the heating element 2 in the atomizing component uses the temperature of the atomizing core 1 as the basis for whether to start. Specifically, when the temperature of the atomizing core 1 reaches the first threshold temperature, the heating element 2 starts; when the temperature of the atomizing core 1 is lower than the first threshold temperature, the heating element 2 does not start, thus realizing the automatic control of the heating element 2. In this way, it can effectively avoid the accumulation of liquid leakage in the liquid 3 to the point of oversaturation due to user negligence. At the same time, this setting can simplify user operation and thus improve the user experience.

[0050] It should be noted that the above-mentioned operating mode in which the atomizing core 1 and the heating element 2 work simultaneously can be either a parallel connection between the atomizing core 1 and the heating element 2, or a series connection between the atomizing core 1 and the heating element 2. For example:

[0051] In some embodiments, when the temperature of the atomizing core 1 is greater than a first threshold temperature but less than a second threshold temperature, the atomizing core 1 is connected in parallel with the heating element 2. For example, the electrical connector includes a first electrical connector and a second electrical connector, and the first and second electrical connectors are respectively connected to different electrode portions (i.e., the positive electrode portion and the negative electrode portion) of the atomizing core 1; one electrical connection terminal of the heating element 2 (hereinafter referred to as the first electrical connection terminal for ease of description) is electrically connected to one of the first and second electrical connectors, and when the temperature of the atomizing core 1 is less than the first threshold temperature, the other electrical connection terminal of the heating element 2 (hereinafter referred to as the second electrical connection terminal for ease of description) is in a suspended state (i.e., neither electrically connected to the atomizing core 1 nor to the electrical connector; of course, in specific implementations, the other electrical connection terminal of the heating element 2...). The connector can also be electrically connected to the atomizer core 1, but it should be ensured that the heating element 2 and the electrical connector connected to it are connected to the same electrode part of the atomizer core 1 (for example, both are connected to the positive electrode of the atomizer core 1). When the temperature of the atomizer core 1 reaches the first threshold temperature, the electrical connection state between the electrical connector and the atomizer core 1 remains unchanged, the electrical connection state between the first electrical connection end of the heating element 2 and the electrical connector remains unchanged, and the second electrical connection end of the heating element 2 changes from a suspended state to being electrically connected to the other of the first electrical connector and the second electrical connector (that is, if the first electrical connection end of the heating element 2 is electrically connected to the first electrical connector, then the second electrical connection end of the heating element 2 is electrically connected to the second electrical connector); in this way, the parallel connection between the atomizer core 1 and the heating element 2 is realized.

[0052] In the above description, the change in the electrical connection state of the second connection terminal of the heating element 2 can be achieved by setting a control component and a control switch. Alternatively, the second electrical connection terminal of the heating element 2 can be made of a heat-deformable metal material. When the temperature of the atomizing core 1 rises, the temperature on the atomizing core 1 can be transferred to the heating element 2 through the electrical connector, thereby causing the second electrical connection terminal of the heating element 2 to automatically deform under the rising temperature and electrically connect to the other of the first and second electrical connectors. In specific implementations, the second connection terminal of the heating element 2 can be made of a bimetallic strip or a memory metal with a two-way memory effect.

[0053] In other embodiments, when the temperature of the atomizing core 1 is greater than a first threshold temperature but less than a second threshold temperature, the atomizing core 1 and the heating element 2 are connected in series. Specifically, in this embodiment, the heating element 2 is electrically connected to both the atomizing core 1 and the electrical connector, and both the electrical connector and the heating element 2 connected thereto are electrically connected to the same electrode portion of the atomizing core 1. When the temperature of the atomizing core 1 is less than the first threshold temperature, the electrical connector is electrically connected to the atomizing core 1 to short-circuit the heating element 2. When the temperature of the atomizing core 1 is greater than the first threshold temperature but less than the second threshold temperature, the electrical connection between the electrical connector and the atomizing core 1 is broken (for example, refer to...). Figure 6(The state of the middle electrode plate 4 and the atomizing core 1) At this time, the heating element 2 and the atomizing core 1 will be connected in series, so that the current flows through the heating element 2, thereby heating the heating element 2 and atomizing the liquid in the liquid 3.

[0054] In the above embodiment, when the heating element 2 is activated, the total resistance of the heating circuit increases because the heating element 2 is connected in series with the atomizing core 1, and the overall power of the atomizing assembly decreases. However, since the atomization area changes from only the atomizing core 1 participating in atomization to both the atomizing core 1 and the heating element 2 participating in atomization, the entire atomization area increases. Therefore, the overall atomization volume of the atomizing assembly does not decrease after the heating element 2 is activated. Furthermore, in this configuration, when the heating element 2 is activated, the power of the atomizing core 1 decreases significantly, causing its temperature to drop accordingly, thus avoiding the problem of dry burning caused by overheating of the atomizing core 1.

[0055] Furthermore, in some embodiments, such as Figures 1-6 As shown, the electrical connector is an electrode plate 4, and the electrode plate 4 has an electrical connection portion 301 that can be electrically connected to the atomizing core 1. This electrical connection portion 301 is made of a heat-deformable metal material; thus, the electrical connection portion 301 can deform with the temperature change of the atomizing core 1, thereby changing the electrical connection state between the electrical connection portion 301 and the atomizing core 1. In this configuration, the inherent properties of the metal material are utilized to cause the electrical connection portion 301 to bend and deform at a preset temperature, thereby breaking the electrical connection between the electrical connection portion 301 and the atomizing core 1, resulting in high reliability. Furthermore, since no other structure is needed to control the on / off state of the electrical connection between the electrical connection portion 301 and the atomizing core 1, this configuration also simplifies the structure of the atomizing assembly.

[0056] In an optional embodiment, the electrical connection portion 301 is a bimetallic strip, and when the temperature of the atomizing core 1 is greater than a first threshold temperature, the bimetallic strip bends away from the atomizing core 1 to disconnect the electrical connection between the electrical connection portion 301 and the atomizing core 1. In an exemplary embodiment, such as Figures 1-4 As shown, the bimetallic strip is a composite material made of brass and iron. Copper is on the side closer to the atomizer core 1, serving as the active layer, while iron is on the side farther from the atomizer core 1, serving as the passive layer. Due to the different coefficients of thermal expansion of the two metal layers, when the temperature rises, the deformation of the active layer is greater than that of the passive layer. This causes the bimetallic strip to bend towards the passive layer, thus breaking the electrical connection between the atomizer core 1 and the electrical connection part 301. Conversely, when the temperature of the bimetallic strip decreases, it gradually recovers, thereby restoring the electrical connection between the atomizer core 1 and the electrical connection part 301.

[0057] In an optional embodiment, the electrical connection portion 301 may also be a shape memory metal, specifically a shape memory metal with a two-way memory effect, meaning that the shape memory metal can recover its high-temperature phase shape at high temperatures and its low-temperature phase shape when cooled. In an exemplary embodiment, the aforementioned shape memory metal may be a nickel-titanium alloy, etc.

[0058] Of course, in some other embodiments, the control structure can also be set to disconnect the electrical connection between the electrical connection part 301 and the atomizing core 1 when the temperature of the atomizing core 1 reaches the first threshold temperature by means of a temperature sensor and an electronic switch.

[0059] In some embodiments, such as Figure 4 As shown, the heating element 2 includes a first contact 201, a second contact 202, and a heating body 203. The first contact 201 is electrically connected to the electrode plate 4, and the second contact 202 is electrically connected to the atomizing core 1. The heating body 203 is disposed between the first contact 201 and the second contact 202, and is integrally formed with or electrically connected to the first contact 201 and the second contact 202. The liquid absorber 3 is disposed on the side of the heating body 203 away from the atomizing core 1, and the heating body is provided with a channel that can guide the leakage of liquid from the atomizing core 1 to the liquid absorber 3. During the use of the atomizing assembly, when the liquid leaking from the atomizing core 1 flows along the second contact plate 202 to the heating body 203, it can flow through the channel on the heating body 203 to the liquid absorber 3. When the heating body 2 is not activated, the liquid absorber 3 stores the liquid leaking from the atomizing core 1. After the heating body 2 is activated, the liquid stored in the liquid absorber 3 flows to the heating body 203 and is atomized under the action of the heating body 203, thus realizing the reuse of the liquid leaking from the atomizing core 1. In a specific implementation, the heating body 203 can be set as a metal sheet with openings, which is more conducive to increasing the heating area of ​​the heating body 203.

[0060] In some embodiments, when the temperature of the atomizing core 1 exceeds a second threshold temperature, the heating circuit is configured in a circuit-breaking mode, meaning that both the atomizing core 1 and the heating element 2 are in a circuit-breaking state with no current flowing through them. This addresses the issue of continuous dry burning caused by the depletion of the atomized liquid in the multi-firing mode. As an example, the portion of the heating element 2 that makes conductive contact with the atomizing core 1 (e.g., the second contact 202), and the portion of the electrical connector that makes conductive contact with the atomizing core 1 (e.g., the electrical connection portion), are all thermally deformable portions, enabling the heating circuit formed by the atomizing core 1, the heating element 2, and the electrical connector to automatically switch between single-firing mode, multi-firing mode, and circuit-breaking mode at different threshold temperature conditions.

[0061] The channels provided on the heating element 203 can be adapted to specific implementations as needed, but it must be ensured that the liquid flowing into the heating element 203 can be promptly diverted to the liquid absorber 3 to prevent the heating element 203 from being submerged. In an exemplary embodiment, the channels on the heating element 203 can be elongated through holes (see specific examples). Figure 4 Alternatively, it can be a circular through hole set on the heating body 203.

[0062] Furthermore, in some embodiments, the resistance of both the first contact 201 and the second contact 202 is less than the resistance of the heating element 203. Thus, when the heating element 2 is activated, the lower resistance of the first contact 201 and the second contact 202 reduces ineffective heat generation, thereby improving overall energy efficiency. In an exemplary embodiment, the heating element 203 is made of nickel-chromium alloy or a material composed of iron-chromium-aluminum; the first contact 201 and the second contact 202 are made of brass.

[0063] In some embodiments, the heating power of the heating element 2 accounts for 20%-30% of the total heating power of the atomizing assembly. This power setting avoids excessively rapid liquid consumption in the liquid 3 and effectively reduces the temperature of the atomizing core 1, thereby improving the service life of the atomizing assembly. In an exemplary embodiment, the resistance range of the heating element 203 in the heating element 2 can be set to 0.4Ω-0.6Ω, so that the heating power of the heating element 2 accounts for 20%-30% of the total heating power of the atomizing assembly. Of course, in specific implementations, the heating power of the heating element 2 can be adaptively adjusted according to the oil leakage rate of the atomizing core 1. Specifically, when the oil leakage rate of the atomizing core 1 is fast, the heating power of the heating element 2 can be appropriately increased; when the oil leakage rate of the atomizing core 1 is slow, the heating power of the heating element 2 can be appropriately decreased.

[0064] In some embodiments, such as Figures 1-4 As shown, electrode plate 4 includes a positive electrode plate and a negative electrode plate; heating element 2 includes a first heating element and a second heating element, and the first heating element is electrically connected to the positive electrode plate and the atomizing core 1, and the second heating element is electrically connected to the negative electrode plate and the atomizing core 1. In this configuration, the first heating element and the second heating element can be activated as needed, so that the liquid consumption rate in the liquid 3 can be adjusted as needed.

[0065] Of course, in some other embodiments, only one heating element 2 may be provided, and the heating element 2 may be connected to the atomizing core 1, as well as the positive electrode plate or the negative electrode plate.

[0066] Furthermore, based on the aforementioned first and second heating elements, in some embodiments, the electrical connection portion 301 of the positive electrode and the electrical connection portion 301 of the negative electrode are identical, meaning they are identical in material, size, etc. Thus, during operation, the deformation of the electrical connection portion 301 of the positive electrode and the electrical connection portion 301 of the negative electrode is completely identical, thereby enabling the positive and negative electrodes to simultaneously disconnect their electrical connection with the atomizing core 1 at the same temperature. More preferably, when the electrical connection between the positive electrode plate's electrical connection portion 301 and the atomizing core 1 is disconnected, and when the electrical connection between the negative electrode plate's electrical connection portion 301 and the atomizing core 1 is disconnected, the temperature of the atomizing core 1 is within the range of 220℃-260℃. That is, the range of the first threshold temperature is 220℃-260℃. When the temperature of the atomizing core 1 reaches a certain temperature within the range of 220℃-260℃, the electrical connections between the positive electrode plate's electrical connection portion 301 and the negative electrode plate's electrical connection portion 301 and the atomizing core 1 are both disconnected. For example, in a specific implementation, the first threshold temperature can be 225℃, 222℃, or 227℃, etc.

[0067] Since 220℃-260℃ is close to the dry burning temperature of the heating element of atomizing core 1, at this time, the amount of liquid remaining in the liquid storage structure (such as the oil tank below) is small, while the amount of liquid stored in the liquid absorbing 3 is large. At this time, the first heating element and the second heating element are activated, which can reduce the power of atomizing core 1 and lower its temperature, thereby avoiding the dry burning problem caused by the excessive temperature of atomizing core 1.

[0068] Furthermore, it should be noted that, in specific implementations, due to factors such as assembly errors and production errors, the temperature of the atomizing core 1 when the electrical connection between the positive electrode plate's electrical connection 301 and the atomizing core 1 is disconnected may differ from the temperature of the atomizing core 1 when the electrical connection between the negative electrode plate's electrical connection 301 and the atomizing core 1 is disconnected. However, the difference is small, and both fall within the temperature range of 220℃-260℃. This situation also falls within the protection scope of this application. Moreover, at this time, the temperature of the atomizing core 1 when the electrical connection between the positive electrode plate's electrical connection 301 and the atomizing core 1 is disconnected is considered equivalent to the temperature of the atomizing core 1 when the electrical connection between the negative electrode plate's electrical connection 301 and the atomizing core 1 is disconnected.

[0069] In other embodiments, the electrical connection portions of the positive electrode and the negative electrode are configured to disconnect from the atomizing core 1 at different temperatures. That is, in this embodiment, the heating element 2 connected to the positive electrode and the heating element 2 connected to the negative electrode are connected in series in the heating circuit at different temperatures of the atomizing core 1. Since the power is lower when only a single heating element 2 is connected in series in the heating circuit, the liquid consumption rate in the liquid 3 is lower, thus making the liquid consumption in the liquid 3 even slower.

[0070] Furthermore, in specific implementations, the electrical connection portion 301 of the positive electrode sheet and the electrical connection portion 301 of the negative electrode sheet can be set to differ in width, upward angle, and / or thickness; so that the electrical connection portion of the positive electrode sheet and the electrical connection portion of the negative electrode sheet are configured to disconnect from the atomizing core at different temperatures.

[0071] Furthermore, when the electrical connection between the positive electrode plate's electrical connection portion 301 and the negative electrode plate's electrical connection portion 301 is disconnected from the atomizing core 1, the temperature of the atomizing core 1 is between 180℃ and 220℃. When the electrical connection between the other electrode plate's electrical connection portion 301 and the atomizing core 1 is disconnected, the temperature of the atomizing core 1 exceeds 220℃. Simultaneously, as mentioned above, when the temperature of the atomizing core 1 exceeds 220℃, both heating elements are connected in series in the heating circuit, which further reduces the power of the atomizing core 1, lowering its temperature and preventing dry burning due to excessively high temperatures.

[0072] Furthermore, this application embodiment also provides an electronic atomizing device, which includes an oil cup and the aforementioned atomizing component. The oil cup contains a liquid storage chamber and a first channel for forming a gas flow channel 19. The atomizing core 1 is disposed at the bottom of the liquid storage chamber and communicates with the liquid in the chamber. A portion of the gas flow channel 19 is defined between the atomizing core 1 and the heating element 2. It should be noted that since the electronic atomizing device includes the aforementioned atomizing component, the beneficial effects of the atomizing component are detailed above and will not be repeated here.

[0073] In some embodiments, the electronic atomizing device includes an anti-dry-burn component for controlling the rate at which liquid (e.g., e-liquid) is consumed in the inhaled liquid 3. This anti-dry-burn component monitors the temperature of the heating element 2 and controls the connection between the heating element 2 and the power supply based on the temperature of the heating element 2, thereby preventing the heating element 2 from overheating and causing the liquid inhaled in the inhaled liquid 3 to be consumed too quickly, thus improving the user experience.
