Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to atomizing components and atomizers. Background Technology

[0002] A nebulizer is a device that atomizes an aerosol matrix into an aerosol for user use, and it has been widely used in industries such as medicine and beauty. In related technologies, the atomization principle typically involves overlapping and winding a liquid-guiding cotton pad with a heating element. The cotton pad adheres to the heating element and surrounds its outer circumference. The heating element, when powered, heats up, thus atomizing the aerosol matrix on the cotton pad into an aerosol. However, with continued use, the cotton pad gradually expands during heating and matrix absorption. This expansion causes it to press inward against the heating element, triggering a series of chain reactions.

[0003] When the heating element is subjected to pressure from the liquid-guiding cotton pad, its inner diameter gradually decreases. This change not only directly reduces the airway space for aerosol passage but also indirectly increases the suction resistance experienced by the user. For users seeking a smooth experience, this is undoubtedly a negative impact, reducing overall user satisfaction. Furthermore, different types of aerosol matrices exert varying pressures on the heating element due to differences in viscosity and density. This further leads to significant differences in suction resistance even within the same device for different flavors or types of products, affecting product standardization and consistency. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an atomizing component that addresses the problem of the heating element being compressed and retracted during atomizer use, thus affecting the suction resistance.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] An embodiment of this application provides an atomizing component, including a heating element, a liquid guiding element, and a support element.

[0007] The heating element is sheet-shaped and has a first end and a second end opposite to each other; the heating element is wound to form at least a portion of an atomizing channel and a notch is left between the first end and the second end; a liquid guiding element is sleeved on the outside of the heating element; a support element is disposed in the notch and abuts against the first end and the second end respectively.

[0008] In one embodiment, the heating element is wound into a C-shape, and the support element and the heating element together form an atomization channel.

[0009] In one embodiment, the support includes a support portion; the support portion is arc-shaped, and the center of the arc of the support portion is located within the atomization channel.

[0010] In one embodiment, the thickness of the support portion is greater than or equal to the thickness of the first end and the second end of the heating element.

[0011] In one embodiment, the atomizing assembly further includes a first atomizing tube, which is sleeved on the outside of the liquid guiding member. The side of the first atomizing tube is provided with a first opening groove, and the end face of the support member opposite to the axis of the heating member is provided with a fixing part, which passes through and is fixed in the first opening groove.

[0012] In one embodiment, the liquid guiding element is sheet-shaped and is wrapped around the outside of the heating element. Both ends of the liquid guiding element are extension ends, both of which pass through the first opening groove and extend away from the heating element. The fixing part is clamped between the two extension ends, and the two corresponding extension ends are interference fit with the first opening groove.

[0013] In one embodiment, the atomizing assembly further includes a second atomizing tube, which is sleeved on the first atomizing tube. A second opening groove corresponding to the first opening groove is formed on the side wall of the second atomizing tube, and the two extended ends of the liquid guiding member pass through the second opening groove. The opening orientation of the first opening groove is opposite to the opening orientation of the second opening groove.

[0014] In one embodiment, the positive and negative conductive pins of the heating element are respectively disposed on both sides of the heating element near the first end and the second end.

[0015] In one embodiment, the atomizing assembly further includes an atomizing base with a limiting step. The end of the first atomizing tube near the opening of the first opening groove is sleeved on the atomizing base and abuts against the limiting step.

[0016] In one embodiment, the support member is provided with an inner support portion, which has two ends. The two ends of the inner support portion extend over the first end and the second end of the heating member, respectively, and abut against the inner sidewall of the heating member.

[0017] In one embodiment, the heating element is a heating mesh, and / or the support element is made of ceramic material.

[0018] This application also provides an atomizer, including an atomizing component as described in any of the above.

[0019] Specifically, the atomizing component is located inside the atomizer. One end of the atomizing channel of the atomizing component is connected to the air outlet of the atomizer, and the other end of the atomizing channel of the atomizing component is connected to the air inlet of the atomizer. The positive and negative conductive pins of the heating element are connected to the electrode plates on the atomizer through wires, and the electrode plates are in contact with the electrical contacts of the power supply unit.

[0020] The beneficial effects of this application are:

[0021] The atomizing assembly provided in this application forms a compact atomizing channel through the cooperation of the support and heating elements. The liquid guide tightly surrounds the outside of the support and heating elements. During use, when the liquid guide fully absorbs the atomizing matrix and expands accordingly, it exerts a certain squeezing force on the support and heating elements. At this time, the stable support structure formed by the cooperation between the support and heating elements effectively disperses and bears the squeezing force generated by the liquid guide, thereby improving the problem of the heating element collapsing or deforming into the atomizing channel due to the expansion and squeezing of the liquid guide cotton during use.

[0022] Thanks to this design, the inner diameter of the atomization channel can remain within a relatively constant range during use, which helps maintain a relatively stable draw resistance and thus provides users with a more comfortable and smooth user experience.

[0023] In addition, this atomizing component further improves the working stability of the atomizer by ensuring the stability of the inner diameter of the atomizing channel.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In related technologies, when the atomizer 800 is in use, the liquid-guiding cotton absorbs the atomizing matrix and expands, which in turn compresses the heating element. This compression causes the heating element to deform, gradually reducing the inner diameter of the atomization channel. This results in a decrease in the consistency of flavor and unstable draw resistance, ultimately affecting the user experience.

[0039] An embodiment of this application provides an atomizing component 900, which relates to the field of electronic atomization technology and is mainly used to atomize an aerosol matrix to form an aerosol for user use.

[0040] like Figure 3 As shown, the atomizing component 900 provided in this embodiment includes a heating element 100, a liquid guiding element 300, and a support element 200.

[0041] The heating element 100 is sheet-shaped and has a first end and a second end opposite to each other; the heating element 100 is wound to form at least a part of the atomization channel and a notch 110 is left between the first end and the second end; the liquid guiding element 300 is sleeved on the outside of the heating element 100, and the liquid guiding element 300 is specifically liquid guiding cotton; the support element 200 is disposed in the notch 110 and abuts against the first end and the second end respectively.

[0042] The atomizing assembly 900 provided in this embodiment forms a compact atomizing channel through the cooperation of the support member 200 and the heating member 100. During user operation of the atomizer 800, the liquid guide member 300, as a crucial component, tightly surrounds the support member 200 and the heating member 100. When the liquid guide member 300 fully absorbs the atomizing matrix and expands accordingly, it exerts a certain squeezing force on the support member 200 and the heating member 100. At this time, the stable support structure formed by the cooperation between the support member 200 and the heating member 100 effectively disperses and bears the squeezing force generated by the liquid guide member 300, thereby ensuring that the heating member 100 does not collapse or deform into the atomizing channel when squeezed.

[0043] In some embodiments, the heating element 100 is wound in a C-shape, and the support member 200 and the heating element 100 together form an atomization channel. Specifically, the support member 200 and the heating element 100 together form a cylindrical shape. This cylindrical design is based on fluid dynamics and structural mechanics. Specifically, when the liquid guide member 300 absorbs the atomization matrix and expands, it generates a certain amount of compressive force. The cylindrical structure formed by the support member 200 and the heating element 100 effectively disperses and bears this compressive force, avoiding structural damage caused by excessive local pressure. This design significantly improves the deformation resistance of the heating element 100, enabling it to maintain structural stability and functional integrity even under long-term use or complex environments, thereby further enhancing the operational stability and reliability of the entire atomization device.

[0044] In some embodiments, the support member 200 includes a support portion; the support portion is arc-shaped, with the center of the arc located within the atomization channel; this arrangement greatly facilitates the support fit between the support portion and the heating element 100. Through this design, the support portion can more effectively support the heating element 100, preventing unnecessary deformation or displacement during operation, thereby ensuring the smoothness of the atomization channel. This design not only improves the overall efficiency of the atomization device but also enhances its stability and durability, providing users with a superior user experience.

[0045] In some embodiments, the thickness of the support member 200 is greater than or equal to the thickness of the first and second ends of the heating element 100. This design is based on the following considerations: First, by increasing the thickness of the support member 200, its structural strength and stability can be significantly improved, enabling it to better withstand the pressure and load from the heating element 100. Second, when the thickness of the support member 200 is greater than or equal to the thickness of the first and second ends of the heating element 100, stress concentration and deformation problems that may be caused by differences in material thickness can be effectively reduced, thereby further improving the support effect of the support member 200 on the heating element 100. This design not only optimizes the structural performance of the entire atomizing assembly 900 but also ensures its stability and reliability during long-term use.

[0046] In some embodiments, the support member 200 has corresponding mating grooves on its end faces opposite to the first and second ends, with the first and second ends respectively abutting into the corresponding mating grooves. This design brings several significant advantages: First, the guiding and limiting effect of the mating grooves further reduces the probability of the first and second ends misaligning and disengaging during assembly. This means that during assembly, workers can more easily and accurately install the first and second ends of the heating element 100 into the corresponding positions on the support member 200 without worrying about assembly errors caused by improper operation.

[0047] Secondly, the design of the mating grooves simplifies the installation process and improves assembly efficiency. Workers only need to align the first and second ends of the heating element 100 with the mating grooves on the support 200, and then press to achieve a secure assembly, without the need for additional fixing measures or tools.

[0048] like Figure 2 As shown, in some embodiments, the atomizing assembly 900 further includes a first atomizing tube 400, which is sleeved on the outside of the liquid guiding member 300. The side of the first atomizing tube 400 is provided with a first opening groove 410. The end face of the support member 200 opposite to the axis of the heating member 100 is provided with a fixing part 210, which passes through and is fixed in the first opening groove 410. The cooperation between the fixing part 210 and the first opening groove 410 can not only improve the stability of the atomizing assembly 900 during use and prevent performance degradation or damage caused by the relative rotation between the heating member 100 and the first atomizing tube 400, but also simplify the assembly process of the atomizing assembly 900 and improve assembly efficiency and accuracy.

[0049] In some embodiments, the liquid guide 300 is sheet-shaped and is wrapped around the outside of the heating element 100. Both ends of the liquid guide 300 are extension ends 310. Both extension ends 310 pass through the first opening groove 410 and extend away from the heating element 100. Specifically, the extensions are inserted into the liquid storage chamber 820 of the atomizer 800. This design allows the liquid guide 300 to directly contact the atomizing matrix in the liquid storage chamber 820, thereby effectively absorbing the atomizing matrix for use in the subsequent atomization process. The fixing part 210 is clamped between the two extension ends 310, and the two corresponding extension ends 310 are interference-fitted with the first opening groove 410. This design not only enhances the connection strength between the extension ends 310 and the first opening groove 410, but also further restricts the relative movement between the liquid guide 300 and the heating element 100, thereby improving the stability and reliability of the entire atomization assembly 900.

[0050] like Figure 1As shown, in some embodiments, the atomizing assembly 900 further includes a second atomizing tube 600, which is sleeved on the first atomizing tube 400. A second opening groove 610 corresponding to the first opening groove 410 is formed on the side wall of the second atomizing tube 600. The two extended ends 310 of the liquid guiding member 300 pass through the second opening groove 610. The opening orientation of the first opening groove 410 is opposite to the opening orientation of the second opening groove 610. Specifically, when the extended ends 310 of the liquid guiding member 300 pass through the first opening groove 410 and the second opening groove 610, they are clamped by the two opening grooves, thus being firmly fixed within the atomizing channel. This design not only improves the structural stability of the atomizing assembly 900 but also ensures the positional accuracy of the liquid guiding member 300 and the support member 200 during the atomization process.

[0051] Furthermore, this complementary setup further simplifies the assembly process of the atomizing component 900. The worker only needs to fit the second atomizing tube 600 onto the first atomizing tube 400 and ensure that the extension end 310 of the liquid guide 300 passes through the two opening slots, without requiring additional fixing measures or tools. This not only improves assembly efficiency but also reduces the error rate during assembly.

[0052] like Figure 4 As shown, in some embodiments, the positive and negative conductive pins 700 of the heating element 100 are respectively disposed on both sides of the heating element 100 near the first end and the second end; specifically, these two positive and negative conductive pins 700 are not directly disposed on the body of the heating element 100, but are disposed on both sides of the support member 200. The support member 200, as an important support and fixing structure of the heating element 100, has a crucial impact on the performance of the entire atomizing assembly 900 due to its position and stability. By disposing the positive and negative conductive pins 700 on both sides of the support member 200, not only is the installation position of the positive and negative conductive pins 700 precisely defined, but it also ensures that they can be stably connected in the circuit, preventing circuit failure due to improper positioning or incorrect installation.

[0053] Furthermore, this design has another important advantage: it effectively prevents short circuits caused by contact between the positive and negative conductive pins 700. During the operation of the atomizing assembly 900, if the positive and negative conductive pins 700 accidentally come into contact, it could cause a short circuit, damaging the entire atomizing assembly 900 or even leading to more serious consequences. By placing the positive and negative conductive pins 700 on opposite sides of the support 200, this potential safety hazard is effectively avoided, providing a strong guarantee for the stable operation of the atomizing assembly 900.

[0054] In some embodiments, the atomizing assembly 900 further includes an atomizing base 500, which has a limiting step 510. The end of the first atomizing tube 400 near the opening of the first opening slot 410 is fitted onto the atomizing base 500 and abuts against the limiting step 510. Through the cooperation of the atomizing base 500 and the limiting step 510, the entire installation and positioning process of the atomizing assembly 900 becomes simpler and more accurate. Workers only need to fit the first atomizing tube 400 onto the atomizing base 500 and make it abut against the limiting step 510 to easily complete the installation and positioning of the atomizing assembly 900 and the first atomizing tube 400. This design not only improves assembly efficiency but also reduces the error rate during assembly, providing strong support for the mass production of the atomizing assembly 900.

[0055] Furthermore, the introduction of the atomizing base 500 further enhances the overall structural stability of the atomizing assembly 900. During atomization, vibrations and impacts are generated between the various components. Without a stable support structure, this could lead to loosening or damage between the components. The presence of the atomizing base 500 effectively disperses these vibrations and impacts, thereby protecting the normal operation of each component.

[0056] like Figure 6 As shown, in some embodiments, the support member 200 is provided with an inner support portion 220, which has two extending ends 310. These two extending ends 310 respectively extend beyond the first and second ends of the heating element 100 and abut tightly against the inner wall of the heating element 100. On the one hand, the support member 200 provides abutment support to the first and second ends of the heating element 100; on the other hand, the inner support portion 220 provides additional support to the inner wall of the heating element 100. This design makes the cylindrical atomizing channel structure formed by the heating element 100 and the support member 200 more compact and stable, thereby optimizing the user experience.

[0057] In some embodiments, the heating element 100 is a heating mesh. Compared to traditional heating wires or heating plates, the heating mesh has a larger surface area, meaning that under the same heating power, it can transfer heat to the surrounding atomizing matrix more evenly and quickly. Therefore, using a heating mesh as the heating element 100 not only effectively improves atomization efficiency but also makes the atomized mist finer and more uniform, thereby enhancing the user experience. The support element 200 is made of ceramic, which is used as the main material. This choice is not accidental but based on a series of excellent properties of ceramic. First, ceramic has extremely high hardness and wear resistance, capable of withstanding various mechanical stresses and frictions that may occur during atomization. Second, ceramic also has good thermal stability and chemical inertness, maintaining stable performance in high-temperature and corrosive environments, thus ensuring that the support element 200 will not deform or be damaged due to heat or chemical reactions during long-term use. Finally, ceramic material also has good insulation properties, which can effectively isolate the heating element 100 from the external environment and improve the safety performance of the entire atomizing assembly 900. Of course, in other embodiments of this application, the support member 200 can also be made of other materials with supporting properties and insulation properties. In addition, if the usage scenario requires it, the support member 200 can also be made of a material with a certain degree of elasticity to improve the user experience.

[0058] like Figure 5 As shown, embodiments of this application also provide an atomizer 800, including the atomizing component 900 as described in the foregoing embodiments.

[0059] Specifically, the atomizing component 900 is disposed inside the atomizer 800, and the atomizer 800 is provided with a liquid storage chamber 820. The liquid guiding component 300 of the atomizing component 900 passes through the liquid storage chamber 820. One end of the atomizing channel of the atomizing component 900 is connected to the air outlet 810 of the atomizer 800, and the other end of the atomizing channel of the atomizing component 900 is connected to the air inlet of the atomizer 800.

[0060] In one embodiment, the atomizer 800 further includes a power supply component 830, which may be detachably connected to the atomizer 800 or be an integral part thereof. In other embodiments, the atomizer 800 is configured to work with an external power supply component, and the atomizer 800 itself does not include the power supply component 830.

[0061] When a user begins using the atomizer 800, they simply inhale through the outlet 810. This action triggers airflow from the inlet into the atomization channel, and simultaneously, the power supply component 830 begins supplying power to the heating element 100. Upon receiving electrical energy, the heating element 100 rapidly heats up, generating sufficient heat to act on the atomization matrix, heating it and converting it into an aerosol. During this process, the airflow mixes thoroughly with the heated atomization matrix, forming a fine and uniform aerosol. Finally, this aerosol enters the user's mouth through the outlet 810 with the user's inhalation, ready for use.
