[0002] Atomizers and electronic atomization devices have been widely used at present. An atomizer consists of an atomization heating component, an air passage, a power source, etc. During operation, the atomization heating component directly atomizes a liquid or semi-liquid working substance into an aerogel with certain functional components for use. The working principle of the atomizer is to cause a state change of the working substance, evaporating from a liquid state into a gaseous state. This process is completed by the atomization heating component, which is composed of a heating element, a matrix, etc. The heating element is powered on to vaporize the working substance, and the matrix is used for liquid conduction, generally using cotton or ceramics.

[0003] For a ceramic matrix, the working substance is usually transported to the heating element for atomization under capillary action. The heating element directly heats the working substance from room temperature to the vaporization temperature (i.e., the atomization temperature), and there are the following problems: 1. Frequently, the working substance cannot reach the heating element in time, resulting in dry burning of the heating element, generating burnt odors and other harmful substances, and reducing the service life of the atomization heating component, thereby affecting the user experience; 2. Due to the large temperature difference, oil splashing will occur, that is, particulate working substances will splash, and the cooled working substance particles will flow back into the air passage, causing blockage of the air passage.

[0039] In the description of the present invention, it should be noted that unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0040] Refer to Figures 1 to 7 to describe the atomizing and heating component 100 of the embodiments of the present invention.

[0041] The atomizing and heating component 100 is a key component of an atomizer (not shown in the figure). A liquid storage cavity and an atomizing cavity (not shown in the figure) are provided in the atomizer. The liquid storage cavity and the atomizing cavity are isolated from each other and not connected. The liquid storage cavity is used to store a working substance represented by an aerosol-forming matrix. The smoke formed after the working substance is atomized overflows from the atomizing cavity. The atomizer is also provided with an air inlet channel and a suction channel (not shown in the figure). The air inlet channel communicates the outside and the atomizing cavity, and the suction channel also communicates the outside and the atomizing cavity. External air enters the atomizing cavity through the air inlet channel to carry the smoke in the atomizing cavity, and then the smoke is sucked out by the user through the suction channel.

[0042] When the atomizing and heating component 100 is working, it directly atomizes a liquid or semi-liquid working substance into an aerogel. The atomizing and heating component 100 can adopt a ceramic core. The working substance is guided to the heating body through the micropores of the ceramic core. The heating body directly heats the working substance from room temperature to the vaporization temperature, generally above 200 °C. Thus, the temperature difference between the atomizing temperature and room temperature is relatively large. As a result, the following defects occur: the oil guiding rate of the ceramic core is relatively low. If the working substance fails to be guided to the heating body in time, it is easy to cause dry burning of the heating body, resulting in the heating body producing a burnt smell and other harmful substances, which in turn affects the user experience; due to the large temperature difference, oil sputtering will occur, that is, particulate working substances splash; due to the large amount of splashing particulate working substances, there is a relatively large amount of condensed working substance in the atomizer, which will flow back into the airway and cause airway blockage.

[0043] Refer to Figures 1 - 3 As shown, the atomizing and heating component 100 according to the first aspect embodiment of the present invention is used to atomize a liquid or semi-liquid working substance. It includes a ceramic matrix 103, a first heating body 101, and a second heating body 102. The first heating body 101 is connected to the ceramic matrix 103 and is used to heat the working substance to a first temperature; the second heating body 102 is used to heat the working substance to a second temperature; wherein, the working substance can flow from the first heating body 101 to the second heating body 102, the first temperature is lower than the atomizing temperature of the working substance, and the second temperature is higher than or equal to the atomizing temperature of the working substance.

[0044] It should be noted that the liquid or semi-liquid working substance can be an oil or a paste. The main difference between a liquid and a semi-liquid lies in the viscosity. The working substance can be a medicine for treating respiratory and lung diseases, or an item with a calming effect or enhancing excitability, or e-liquid, e-paste, etc.

[0045] It should also be noted that the atomization temperature is related to the type of working substance. For example, for e-liquid, its atomization temperature is usually between 220°C and 250°C, such as 220°C, 230°C or 250°C, etc. The first temperature is lower than the atomization temperature of the working substance, and the second temperature is higher than or equal to the atomization temperature of the working substance. The value range of the first temperature can be 40°C to 180°C, such as the preheating temperature can be 40°C, 70°C, 120°C or 180°C, etc. Thus, the first heating element 101 is used to preheat the working substance to increase the temperature of the working substance, and the second heating element 102 is used to atomize the working substance, that is, to heat the working substance from the first temperature to the second temperature, thereby avoiding directly heating the working substance from room temperature to the second temperature, reducing the temperature difference of the working substance before and after atomization, reducing the probability of e-liquid explosion during the atomization process, that is, reducing the splashing of working substance particles, that is, avoiding the reflux of the cooled working substance particles into the airway and preventing airway blockage.

[0046] It should also be noted that the ceramic matrix 103 can be made of porous ceramic material. Therefore, the ceramic matrix 103 contains a large number of micropores and has a certain porosity. The porosity can be defined as the percentage of the volume of pores in an object to the total volume of the material in its natural state. The porosity of the ceramic matrix 103 is relatively low. For example, the porosity of the ceramic matrix 103 is 8% - 22%. At the same time, the viscosity of the working substance is relatively large at room temperature, and the value range of this viscosity can be 40 mPa·S - 1300 mPa·S. A relatively large viscosity will cause the working substance to not be conducted to the heating element quickly. In the atomization heating component 100 in the above-mentioned embodiment of the present invention, when the atomizer works, the first heating element 101 preheats the working substance. Since the viscosity of the working substance is inversely proportional to the temperature, the viscosity of the working substance after preheating will be lower than that of the working substance at room temperature, thereby reducing the resistance of the working substance flowing through the inside of the ceramic matrix 103. At this time, the working substance with reduced viscosity will reach the second heating element 102 through the micropores inside the ceramic matrix 103 at a relatively faster speed in a short time for atomization, so as to avoid dry burning caused by insufficient infiltration amount of the working substance per unit time in the ceramic matrix 103 and extend the service life of the atomization heating component 100. It can be understood that the first heating element 101 can be a film-shaped preheating film or a wire-shaped preheating wire, such as a resistance wire, and can be made of stainless steel material, titanium metal material or titanium alloy material, etc. According to the actual needs, the first heating element 101 can be connected to the ceramic matrix 103 through printing process, spraying process or electroplating process. Further explanation is that the second heating element 102 can be a film-shaped heating film or a wire-shaped heating wire, such as a resistance wire, and can be made of stainless steel material, titanium metal material or titanium alloy material, etc. The second heating element 102 can be directly attached to the end face of the ceramic matrix 103. According to the actual needs, the second heating element 102 can be connected to the ceramic matrix 103 through printing process, spraying process or electroplating process.

[0047] In some embodiments, when the working substance is a substance that can be inhaled, by setting a secondary heating element for preheating, the working substance is heated to a certain temperature before entering the second heating element 102. This temperature can be artificially controlled to make the working substance undergo a quantitative change before vaporization without vaporizing. It has two functions. One is to reduce the temperature difference, and the other is to catalyze the large molecular groups in the working substance into small molecular groups under the condition of heating to improve the efficacy of the working substance. For example, when the working substance is e-liquid, the secondary heating can make the e-liquid volatilize the fragrance and nicotine more fully. Since the oil supply is sufficient, when the second heating element 102 works, it will not cause local oil shortage and high temperature, avoid the generation of harmful substances caused by dry burning, and at the same time reduce the carbon deposition at local high temperatures. Therefore, the service life will also be extended.

[0048] It should be noted that the atomization heating component 100 further includes a first electrical connector (not shown in the figure) for connecting to the positive electrode of the power supply and a second electrical connector (not shown in the figure) for connecting to the negative electrode of the power supply. The first electrical connector and the second electrical connector are respectively connected to the first electrode 201 of the first heating element and the second electrode 301 of the second heating element, thereby realizing the power supply of the atomization heating component 100 by the power supply.

[0049] Referring to Figure 1 、 Figure 4 As shown, the first heating body 101 and the second heating body 102 are respectively located on two opposite end faces of the ceramic substrate 103. For example, specifically, the first heating body 101 is located on the upper end face 104 of the ceramic substrate 103, and the second heating body 102 is located on the lower end face 105 of the ceramic substrate 103. Thus, the working substance can flow from the first heating body 101 to the second heating body 102 under the action of its own gravity and capillary action, facilitating the flow of the working substance. It can be understood that according to the specific structural design of the atomizer, the first heating body 101 and the second heating body 102 can be respectively located on the front end face and the rear end face (not shown in the figure) of the ceramic substrate 103, or the left end face and the right end face (not shown in the figure).

[0050] Referring to Figure 1 、 Figure 3 、 Figure 4 As shown, the ceramic substrate 103 is generally in an approximate square structure, which has an upper end face 104, a lower end face 105, and a plurality of side faces 107. Among them, the first heating body 101 is located on the upper end face 104, the second heating body 102 is located on the lower end face 105, and at least part of the upper end face 104 and at least part of the lower end face 105 are permeable regions, so that the working substance can be preheated at the upper end face 104 and enter the interior of the ceramic substrate 103, and flow to the lower end face 105, where it is heated and atomized by the second heating body 102. In order to prevent the unnecessary leakage of the working substance from the ceramic substrate 103, the plurality of side faces 107 of the ceramic substrate 103 are provided as a sealing layer. For example, a silicone coating is provided on the side face 107 of the ceramic substrate 103.

[0051] Referring to Figure 1 、 Figure 4As shown, the ceramic substrate 103 is provided with two blind holes 108, and the two blind holes 108 are respectively located on both sides of the second heating element 102. At least part of the bottom wall 302 of the blind holes 108 is a permeable area. By providing the blind holes 108, a gas return channel can be provided for the liquid storage cavity of the atomizer. When the working substance is gradually consumed, the air pressure in the liquid storage cavity decreases. When the air pressure decreases too much, the working substance will not be able to flow smoothly to the second heating element 102. By providing the blind holes 108 with the bottom wall 302 being a permeable area, since the distance between the bottom wall 302 of the blind holes 108 and the upper end face 104 of the ceramic substrate 103 is small, the gas can conveniently permeate through to supplement the liquid storage cavity, achieving the effect of gas return. Figure 1 and Figure 4 The two vertical arrows on both sides in Figure 4 are the directions of gas return. It can be understood that the upper end face 104 of the ceramic substrate 103 corresponding to the bottom wall 302 of the blind holes 108 is a permeable area. It should be noted that at least one blind hole 108 is provided, such as 1, 3 or more. The blind holes 108 should be arranged avoiding the first heating element 101 and the second heating element 102.

[0052] Referring to Figure 4 As shown, in some embodiments, the blind holes 108 are located on the lower end face 105 where the second heating element 102 is located and on one side of the second heating element 102. The depth of the blind holes 108 can be set to one - half to four - fifths of the thickness of the ceramic substrate 103, achieving a better gas return effect while avoiding liquid leakage.

[0053] Referring to Figure 1 As shown, the parts of the ceramic substrate 103 on both sides of the second heating element 102 are set as thinning areas 109, and the two blind holes 108 are both arranged in the thinning areas 109. By providing the thinning areas 109, the processing cost can be saved. In some embodiments, the surface of the thinning area 109 where the blind holes 108 are arranged is set as an arc surface 106. The second heating element 102 heats the working substance to generate aerosol, and the aerosol is sucked out and used by the user. During the process of sucking out the aerosol, an air flow is generated. By setting the lower side surface 107 of the thinning area 109 as an arc surface 106, the flow process of the air flow can be made smoother, reducing the resistance during the discharge of the aerosol and also avoiding excessive adhesion of the aerosol on the lower end face 105 of the ceramic substrate 103, improving the user experience. Figure 1 The two diagonal arrows in the lower middle part in Figure 1 show the flow direction of the aerosol. It should be noted that the lower side surface 107 of the thinning area 109 is also set as an inclined surface (not shown in the figure), thereby reducing the flow resistance of the aerosol.

[0054] Referring to Figure 6As shown, in some embodiments, a breathable membrane 601 is provided over the opening of the blind hole 108. By providing the breathable membrane 601, while ensuring smooth gas entry into the blind hole 108, aerosol airflow can be prevented from entering the blind hole 108, thereby reducing airflow resistance. At the same time, it can also prevent excessive adhesion of aerosol on the side wall or bottom wall 302 of the blind hole 108, blocking the air return channel. Additionally, when the suction effect is large and the airflow speed is fast, the presence of the blind hole 108 is likely to form noise, such as a whistling sound. By providing the breathable membrane 601, the above situation can be avoided.

[0055] In some embodiments, the first heating element 101 is electrically connected to a temperature control element (not shown in the figure), thereby achieving prevention of dry burning through temperature control. The principle is that the first heating element 101 is electrically connected to a temperature control element. If the working substance is lacking at the second heating element 102, the temperature of the first heating element 101 will rise rapidly. Therefore, it is used to determine whether the working substance needs to be added to the liquid storage cavity of the atomizer, or to perform controls such as pausing first.

[0056] Refer to Figure 7 As shown, in some embodiments, the second heating element 102 is provided as a first resistance wire 701 and a second resistance wire 702. The first resistance wire 701 and the second resistance wire 702 can work alternately as needed. Additionally, the connection circuit of the first resistance wire 701 and the second resistance wire 702 enables the first resistance wire 701 or the second resistance wire 702 to act alone, or the first resistance wire 701 and the second resistance wire 702 to act in parallel, or the first resistance wire 701 and the second resistance wire 702 to act in series, that is, four working modes of single resistance heating, parallel heating, and series heating are realized for the user to select according to needs. It should be noted that the resistances of the first resistance wire 701 and the second resistance wire 702 can be the same or different. The second heating element 102 can also be provided with more than 3 resistance wires to achieve more working modes.

[0057] The atomizer according to the second aspect embodiment of the present invention includes the atomization heating assembly 100 according to the first aspect embodiment of the present invention. For the atomizer according to the second aspect embodiment of the present invention, when the atomization heating assembly 100 of the above embodiment is adopted, the first heating element 101 can achieve a preheating effect to reduce the temperature difference between the working substance and the second temperature, reducing the probability of oil splashing. Additionally, through the preheating effect, the viscosity of the working substance to be introduced into the ceramic matrix 103 can be reduced, avoiding dry burning of the second heating element 102.

[0058] The electronic atomization device according to the embodiment of the third aspect of the present invention includes: a power source, a control circuit, and the atomizer according to the embodiment of the second aspect of the present invention. Among them, the power source is connected to the atomizer and supplies power to the atomizer. The control circuit is used to control the first heating element and the second heating element to heat. According to the electronic atomization device of the embodiment of the third aspect of the present invention, when the atomizer of the above embodiment is adopted, the temperature difference between the working substance and the temperature can be reduced, the probability of oil explosion can be reduced, and the dry burning of the second heating body 102 can be avoided, thereby improving the quality of the electronic atomization device.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
