Abstract
Description

[0002] An electronic atomizing device includes an atomizer and a power supply unit for powering the atomizer. The atomizer contains a reservoir and a coil. The reservoir stores the aerosol matrix, and the coil heats and atomizes the aerosol matrix. An airflow sensor is included in the electronic atomizing device. When the user inhales through the atomizer's mouthpiece, the resulting negative pressure triggers the airflow sensor. The airflow sensor then controls the power supply unit to power the coil, causing it to heat and atomize the aerosol matrix, generating the aerosol for the user to inhale.
[0003] Existing atomizer cores mainly include etched ceramic cores and thick-film ceramic cores. Etched ceramic cores have the advantages of rapid heating, strong power output, and easier extraction of aroma and sweetness, while thick-film ceramic cores have the advantages of a delicate taste and strong throat hit. However, as users' requirements for the taste of aerosols continue to increase, existing etched ceramic cores or thick-film ceramic cores are no longer sufficient to meet user needs.

[0037] See Figure 1 and Figure 2 As shown, in this embodiment, the atomizing core 100 includes a substrate 110 and a heating wire assembly. The substrate 110 includes a liquid-absorbing surface 111 and an atomizing surface 112 facing each other. The substrate 110 is a porous structure with pores inside, allowing the gas-gel matrix of the liquid-absorbing surface 111 to permeate to the atomizing surface 112 through the pores inside the substrate 110. The heating wire assembly is disposed on the atomizing surface 112 of the substrate 110 and includes two heating wires 120 with different structures, namely an etched heating wire 120a and a thick-film printed heating wire 120b.
[0038] The etched heating wire 120a and the thick film printed heating wire 120b have different manufacturing processes and structures. When used in atomizers and electronic atomization devices, the user's inhalation experience is also different.
[0039] The etched heating wire 120a is made by etching a metal film into a specific shape. The etched heating wire 120a and the material used to make the substrate 110 are sintered in a mold to form the substrate 110, and the etched heating wire 120a and the substrate 110 are then connected as a single unit, resulting in the etched atomizing core 100. The etched atomizing core 100 has the advantages of rapid heating, strong burst power, and easier extraction of aroma and sweetness.
[0040] The thick-film printed heating wire 120b is made by adding an inorganic binder to metal powder to form a resistance paste, which is then screen-printed onto the atomizing surface 112 of the substrate 110. After sintering, the thick-film printed heating wire 120b is formed on the atomizing surface 112 of the substrate 110, thus forming the thick-film atomizing core 100. The thick-film atomizing core 100 has the advantages of a delicate taste and a strong throat hit.
[0041] In the prior art, the atomizing core 100 is made of etched sheet heating wire 120a or thick film printed heating wire 120b. However, as users' requirements for the taste of aerosols continue to increase, the existing etched sheet atomizing core 100 or thick film atomizing core 100 can hardly meet user needs.
[0042] In this embodiment, the atomizing core 100 includes a substrate 110 and a heating wire assembly. The substrate 110 includes a liquid absorption surface 111 and an atomizing surface 112. The heating wire assembly is disposed on the atomizing surface 112 of the substrate 110. The heating wire assembly includes an etched sheet heating wire 120a and a thick film printed heating wire 120b. The etched sheet heating wire 120a and the thick film printed heating wire 120b have different manufacturing processes and structures, resulting in different inhalation sensations of the aerosol formed by atomization. When the atomizing core 100 is used in atomizers and electronic atomization devices, the etched sheet heating wire 120a and the thick film printed heating wire 120b can be connected in parallel. That is, the etched sheet heating wire 120a and the thick film printed heating wire 120b can simultaneously atomize the aerosol matrix. When the user inhales, they can obtain a better sweet and fragrant taste as well as a better throat hit, improving the taste of the aerosol generated by atomization and meeting the user's requirements for richness of taste.
[0043] It should be noted that the heating wire assembly may include two heating wires 120 with different structures, namely one etched sheet heating wire 120a and one thick film printed heating wire 120b, but it is not limited to this. The heating wire assembly may also include more than two heating wires 120, depending on the specific situation. When the heating wire assembly includes more than two heating wires 120, at least one etched sheet heating wire 120a and one thick film printed heating wire 120b shall be activated. The other heating wires 120 can serve as backups and be activated when the activated heating wires 120 fail. The backup heating wires 120 may be all etched sheet heating wires 120a or all thick film printed heating wires 120b, or they may be partially etched sheet heating wires 120a and partially thick film printed heating wires 120b, depending on the specific situation. When the heating wire assembly includes two or more heating wires 120, one etched heating wire 120a and one thick film printed heating wire 120b can be used, with the other heating wires 120 serving as backups. However, this is not the only option; all heating wires 120 can also be used, depending on the specific circumstances.
[0044] In some embodiments, the etched heating wire 120a is made of stainless steel, nickel-chromium alloy, or iron-chromium-aluminum alloy. The thick-film printed heating wire 120b comprises metal powder and a binder; the metal powder is made of silver, nickel-chromium alloy, or stainless steel, and the binder comprises glass powder. The substrate 110 is made of ceramic.
[0045] When manufacturing the ceramic atomizing core 100 in this application, an etched heating wire 120a (the etched heating wire 120a is made by etching a metal film into a specific shape) and a ceramic substrate 110 can be manufactured separately. Then, the etched heating wire 120a and the ceramic substrate 110 are integrally formed and sintered to obtain a semi-finished product of the atomizing core 100. Then, an inorganic binder is added to the metal powder to make a resistance paste. The resistance paste is formed on the atomizing surface 112 of the substrate 110 by screen printing. Finally, the ceramic atomizing core 100 is made by sintering.
[0046] The materials and processes used to manufacture the atomizing core 100 in this application are a combination of the materials and processes used to manufacture the etched ceramic atomizing core 100 and the thick-film ceramic atomizing core 100, without adding any other materials or processes, which helps to control the manufacturing cost of the atomizing core 100.
[0047] In some embodiments, the thick film printed heating wire 120b is a porous structure with internal pores.
[0048] The thick-film printed heating wire 120b is a porous structure, which allows the aerosol matrix to permeate evenly into the surface and interior of the thick-film printed heating wire 120b. This increases the contact area between the thick-film printed heating wire 120b and the aerosol matrix, which is beneficial for improving the atomization speed and atomization uniformity of the aerosol matrix.
[0049] In some embodiments, the heating wire 120 includes a heating wire body 121 and contacts 122 disposed at both ends of the heating wire body 121, the heating wire body 121 and the contacts 122 being integrally connected. The heating wire body 121 is a non-intersecting curve, and the heating wire bodies 121 of different heating wires 120 are spaced apart, that is, the heating wire bodies 121 of different heating wires 120 do not intersect. The contacts 122 are used to connect electrodes, so that the heating wire body 121 is energized and heated, and the heating wire body 121 is used to heat and atomize the aerosol matrix.
[0050] The resistance values of both the etched heating wire 120a and the thick-film printed heating wire 120b are 0.8 ohms to 2.0 ohms. Their resistance values can be equal or approximately equal. However, due to differences in structure and manufacturing process, the resistance value per unit length of the heating wire 120a differs from that of the thick-film printed heating wire 120b. Typically, the etched heating wire 120a is longer to ensure that its resistance value is equal or approximately equal to that of the thick-film printed heating wire 120b.
[0051] The heating wire bodies 121 of different heating wires 120 are spaced apart to avoid the heating wires 120 crossing and causing changes in the resistance value of the heating wires 120, which in turn prevents the heating wires 120 from heating the aerosol matrix evenly.
[0052] In some embodiments, a gap is formed between contacts 122 located on the same side of the substrate 110.
[0053] The contacts 122 located on the same side of the substrate 110 are spaced apart, and each heating wire 120 is powered independently. Users can control the activation of any number of etched heating wires 120a and any number of thick film printed heating wires 120b to meet users' personalized suction taste needs.
[0054] It should be noted that the contacts 122 on the same side of the substrate 110 can be spaced apart, but are not limited to this. The contacts 122 on the same side of the substrate 110 can also be partially or completely connected, depending on the situation. Since the different heating wires 120 are connected in parallel, connecting the contacts 122 on the same side of the substrate 110 eliminates the need to supply power to each heating wire 120 separately, which simplifies the power supply circuit of the heating wires 120 and reduces the manufacturing cost of atomizers and electronic atomization devices.
[0055] In some embodiments, at least a portion of the etched heating wire 120a is embedded in the substrate 110, with the lower surface of the etched heating wire 120a away from the liquid absorption surface 111 exposed in the substrate 110. That is, the depth to which the etched heating wire 120a is embedded in the substrate 110 is less than or equal to the thickness of the etched heating wire 120a, ensuring that the lower surface of the etched heating wire 120a away from the liquid absorption surface 111 is exposed in the substrate 110.
[0056] At least a portion of the etched heating wire 120a is embedded in the substrate 110, which increases the contact area between the etched heating wire 120a and the aerosol matrix, thereby improving the atomization speed and uniformity of the aerosol matrix and enhancing the user's inhalation experience.
[0057] In some embodiments, the liquid absorption surface 111 of the substrate 110 is provided with an oil-collecting groove 113, which may be a rectangular cross-section groove.
[0058] An oil tank 113 capable of storing aerosol matrix is provided on the liquid absorption surface 111 to avoid untimely supply of aerosol matrix when the heating wire 120 heats and atomizes the aerosol matrix.
[0059] This embodiment also provides an atomizer, see [link]. Figure 3 and Figure 4As shown, in this embodiment, the atomizer includes an atomizing core 100 and electrodes. The electrodes include a positive electrode 210 and a negative electrode 220, which are respectively connected to a power supply assembly. At least two heating wires 120 with different structures are connected in parallel between the positive electrode 210 and the negative electrode 220, that is, at least one etched sheet heating wire 120a and at least one thick film printed heating wire 120b are connected in parallel between the positive electrode 210 and the negative electrode 220. The etched sheet heating wire 120a and the thick film printed heating wire 120b can work simultaneously.
[0060] The atomizer includes an atomizing coil 100, which comprises a substrate 110 and a heating wire assembly. The substrate 110 includes a liquid absorption surface 111 and an atomizing surface 112. The heating wire assembly is disposed on the atomizing surface 112 of the substrate 110. The heating wire assembly includes an etched sheet heating wire 120a and a thick-film printed heating wire 120b. The etched sheet heating wire 120a and the thick-film printed heating wire 120b have different manufacturing processes and structures, resulting in different inhalation flavors of the aerosol formed. When the atomizing coil 100 is used in the atomizer, the etched sheet heating wire 120a and the thick-film printed heating wire 120b are connected in parallel, meaning that the etched sheet heating wire 120a and the thick-film printed heating wire 120b can simultaneously atomize the aerosol matrix. When the user inhales, they can obtain both a better sweet and fragrant taste and a better throat hit, enhancing the flavor of the aerosol generated and satisfying the user's requirements for a richer flavor profile.
[0061] In some embodiments, the heating wire 120 includes a heating wire body 121 and contacts 122 disposed at both ends of the heating wire body 121. The heating wire body 121 is a non-intersecting curve, and a gap is formed between the heating wire bodies 121 of different heating wires 120. The contacts 122 are used to connect electrodes, and a gap is formed between the contacts 122 located on the same side of the substrate 110. The atomizer also includes a connecting rod 230, which connects at least two spaced contacts 122 on the same side of the substrate 110. The positive electrode 210 is connected to at least two contacts 122 located on one side of the substrate 110 via a connecting rod 230, and the negative electrode 220 is connected to at least two contacts 122 located on the other side of the substrate 110 via a connecting rod 230.
[0062] Since the different heating wires 120 are connected in parallel, when a gap is formed between the contacts 122 located on the same side of the substrate 110, the positive electrode 210 and the negative electrode 220 are simultaneously connected to at least two contacts 122, which can reduce the number of positive electrodes 210 and negative electrodes 220 and reduce the manufacturing cost of atomizers and electronic atomization devices.
[0063] In some embodiments, the heating wire 120 includes a heating wire body 121 and contacts 122 disposed at both ends of the heating wire body 121. The heating wire body 121 is a non-intersecting curve, and the heating wire bodies 121 of different heating wires 120 are spaced apart. The contacts 122 are used to connect electrodes, and the contacts 122 located on the same side of the substrate 110 are connected together. The positive electrode 210 is connected to one contact 122 on one side of the substrate 110, and the negative electrode 220 is connected to one contact 122 on the other side of the substrate 110.
[0064] Since the different heating wires 120 are connected in parallel, when the contacts 122 on the same side of the base 110 are connected, the positive electrode 210 and the negative electrode 220 can be connected to one contact 122 respectively. The positive electrode 210 and the negative electrode 220 are both roughly cylindrical, which is the same as the electrode structure of existing atomizers. This reduces the number of electrodes and allows the use of existing cylindrical electrodes, which helps to reduce the manufacturing cost of atomizers.
[0065] In some embodiments, the heating wire 120 includes a heating wire body 121 and contacts 122 disposed at both ends of the heating wire body 121. The heating wire body 121 is a non-intersecting curve, and a gap is formed between the heating wire bodies 121 of different heating wires 120. The contacts 122 are used to connect electrodes, and a gap is formed between contacts 122 located on the same side of the substrate 110. See also Figure 5 As shown, the contacts 122 are connected to the electrodes one-to-one. That is, one end of each heating wire 120 has a contact 122 connected to a positive electrode 210, and the other end of each heating wire 120 has a contact 122 connected to a negative electrode 220.
[0066] Contact 122 is connected to the electrode in a one-to-one correspondence. A set of positive electrodes 210 and negative electrodes 220 can individually control whether a heating wire 120 is activated. Users can control the activation of any number of etched heating wires 120a and any number of thick film printed heating wires 120b to meet users' personalized suction taste needs.
[0067] This application also provides an electronic atomizing device, which includes the atomizer and power supply components disclosed above, and is connected to the positive electrode 210 and the negative electrode 220.
[0068] The heating wire 120 includes a heating wire body 121 and contacts 122 disposed at both ends of the heating wire body 121. The heating wire body 121 is a non-intersecting curve, and there are gaps between the heating wire bodies 121 of different heating wires 120. The contacts 122 are used to connect electrodes, and there are gaps between the contacts 122 located on the same side of the substrate 110. When the contacts 122 are connected to the electrodes one-to-one, that is, when the contacts 122 at one end of each heating wire 120 are connected to a positive electrode 210 and the contacts 122 at the other end of each heating wire 120 are connected to a negative electrode 220, the power supply component can individually control the connection or disconnection of a set of positive electrodes 210 and negative electrodes 220 connected to each heating wire 120 with the power supply component.
[0069] The electronic atomizing device includes an atomizer and a power supply assembly for powering the atomizer. The atomizer contains a liquid reservoir and an atomizing coil 100. The liquid reservoir stores the aerosol matrix, and the atomizing coil 100 heats and atomizes the aerosol matrix. An airflow sensor is included in the electronic atomizing device. When a user inhales through the atomizer's mouthpiece, the resulting negative pressure triggers the airflow sensor. The airflow sensor then controls the power supply assembly to power the atomizing coil 100, causing it to heat and atomize the aerosol matrix, generating an aerosol for the user to inhale.
