Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic atomizers, and in particular to an anti-dry burning electronic atomizer. Background Art
[0002] As people's health awareness gradually improves, people are aware of the harm of tobacco to the body, so electronic atomizers are produced. Electronic atomizers are also called virtual cigarettes, electronic cigarettes, steam cigarettes, etc. They have the same appearance and taste as cigarettes, and are a non-combustion tobacco substitute product. However, electronic atomizers generally do not contain tar, suspended particles and other harmful ingredients in cigarettes, which greatly reduces the harm to the user's body. Therefore, they are mostly used as a substitute for cigarettes and are deeply loved by smokers.
[0003] At present, the working principle of commercially available electronic atomizers is mainly to use atomization to heat the atomization medium such as smoke oil and evaporate it into an aerosol by electric heating, which is then inhaled by consumers to achieve a smoking experience. In this process, once the atomization medium is reduced to the point where it cannot be supplied to the atomization core, the atomization core will be dry-burned. On the one hand, this seriously reduces the consumer experience. On the other hand, high-temperature dry burning will cause atomization cores such as oil-conducting cotton or oil-conducting ceramics or a small amount of residual smoke oil to undergo chemical reactions, producing harmful gases and affecting the health of consumers. Therefore, the anti-dry burning function of electronic atomizers has become a hot research field. The existing anti-dry burning technology mainly uses the installation of a temperature sensor and sets a threshold in the temperature sensor to prevent dry burning by monitoring whether the temperature in the electronic atomizer exceeds the threshold. However, this method has different atomization temperatures for different types of atomization media, and there is no way to set a unified temperature threshold to prevent dry burning. Summary of the invention
[0004] Based on this, it is necessary to provide a simple and easy to implement anti-dry burning electronic atomizer that can effectively prevent dry burning for different types of atomizing media, in order to address the problem that the existing electronic atomizers still cannot effectively prevent dry burning for different types of atomizing media.

[0008] The atomizing core is used to heat the atomizing medium and the anti-dry burning medium, so that the atomizing medium and the anti-dry burning medium generate a first aerosol and a second aerosol respectively, and then are discharged from the electronic atomizer through the first air passage.
[0009] In one embodiment, the anti-dry burning medium covers the surface of the atomizing medium at one end away from the atomizing core.
[0010] In one embodiment, the anti-dry burning medium is in sheet form.
[0011] In one of the embodiments, the anti-dry burning medium is made by a thinning process.

[0014] In one embodiment, the first aerosol and the second aerosol have different colors, and / or the first aerosol and the second aerosol have different smells, and / or the first aerosol and the second aerosol have different mouthfeels.
[0015] In one embodiment, the atomization assembly further includes an oil seepage plate, which is disposed between the oil storage cavity and the atomization core, the oil storage cavity and the atomization core are matched with each other through the oil seepage plate, and the oil seepage plate is used to infiltrate the atomization medium in the oil storage cavity into the atomization core.
[0016] In one embodiment, the oil seepage plate is provided with a plurality of oil seepage holes arranged at intervals.
[0017] In one embodiment, the atomizer core includes a heating body, oil-conducting cotton and a heating element. The oil-conducting cotton and the heating element are accommodated in the heating body, and the oil-conducting cotton is connected to the heating element.

Therefore, when the atomizing component is heated, the atomizing medium is heated and atomized before the anti-dry-burn medium, so that the first aerosol and the second aerosol with different properties are obtained according to the order of atomization of the atomizing medium and the anti-dry-burn medium. The user can judge whether the atomizing medium is exhausted by sensing the different properties of the first aerosol and the second aerosol, so that the structure of the above-mentioned anti-dry-burn electronic atomizer is simple, and the atomizing core can be prevented from dry burning without installing a sensor. The raw materials of the anti-dry-burn medium are environmentally friendly and harmless and can be mass-produced, and can be adapted to different types of atomizing media.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0025] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “liquid level”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0027] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher liquid level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower liquid level than the second feature.
[0029] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "liquid horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0030] As described in the background technology, existing electronic atomizers mainly use circuit control or residual control methods, such as installing a temperature sensor and setting a threshold in the temperature sensor to prevent dry burning by monitoring whether the temperature in the electronic atomizer exceeds the threshold. However, this method will prevent dry burning because the atomization temperatures of different types of atomizing media are different, and there is no way to set a unified temperature threshold to prevent dry burning. For example, for an atomizing medium with an atomizing temperature of 230°C, the temperature sensor will stop heating when it detects 230°C, but for another atomizing medium with an atomizing temperature of 220°C, the temperature sensor will not alarm and stop heating, and dry burning will still occur.
[0031] In order to solve this problem, the inventor of the present application has conducted in-depth research and designed an anti-dry burning electronic atomizer that is simple and easy to implement and can effectively prevent dry burning for different types of atomization media.
[0032] According to the principle of like dissolves like, when the molecular structures of two different substances are very different, the molecules cannot combine with each other and cannot dissolve in each other. At the same time, when the densities of the two substances are different, the substance with lower density is lighter than the substance with higher density in the same volume. Therefore, when two substances that cannot dissolve in each other are mixed together, the substance with lower density will also float on the surface of the substance with higher density. For example, water and oil, water is a polar molecule, while oil is a non-polar molecule. Polar molecules and non-polar molecules repel each other and cannot dissolve together. At the same time, the density of oil is also less than that of water. Therefore, when water and oil are mixed, the oil will also float on the surface of the water.
[0033] Based on the above principles, the inventor of the present application thought of finding a substance that is insoluble in the atomizing medium and has a density lower than that of the atomizing medium, so that it can float on the surface of the atomizing medium. When the atomizer is powered on, the substance is used to float above the atomizing medium, so that when the atomizing medium below is atomized and consumed first, the substance floating above begins to be heated and atomized. By sensing the atomization state of two different substances in turn, it is determined whether the atomizing medium has been exhausted, thereby achieving the purpose of preventing dry burning. The anti-dry burning electronic atomizer has a simple structure and does not require the aid of sensors, which solves the problem that existing electronic atomizers cannot effectively prevent dry burning for different types of atomizing media.
[0034] The structure of the anti-dry-burn electronic atomizer provided by the present application is described below by taking the anti-dry-burn electronic atomizer as an electronic cigarette and the atomizing medium inside the electronic cigarette as smoke oil as an example. The anti-dry-burn electronic atomizer is used to heat and atomize the atomizing medium inside it to generate an aerosol for the user to inhale, and is used to prevent the state of high-temperature dry burning when the atomizing medium is reduced to the point where it cannot be supplied.
[0035] This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomizer and the method for preventing dry burning of the electronic atomizer disclosed in this application can be used, but not limited to, to prevent the electronic cigarette from continuing to dry burn when the e-liquid supply is insufficient, and can also be used to prevent any other type of electronic atomizer from dry burning when the atomizing medium supply is insufficient, which is not limited here.
[0036] The following combination Figure 1 to Figure 2 , introduces the preferred implementation of the electronic atomizer provided by the present application and the anti-dry burning method based on the electronic atomizer.
[0037] Figure 1 The figure is a schematic diagram of the internal structure of an electronic atomizer 10, which includes a power supply component 100, an atomizer component 200 and a nozzle 300 which are coaxially arranged in sequence along the axial direction defined by the central axis (dotted line in the figure) of the electronic atomizer 10. The atomizer component 200 is connected to one end of the power supply component 100, and the nozzle 300 is connected to the end of the atomizer component 200 away from the power supply component 100. The power supply component 100 is used to provide electrical energy to the atomizer component 200, and the atomizer component 200 is used to accommodate the atomizing medium 40 (i.e., smoke oil), and can heat the atomizing medium 40 under the action of the electrical energy provided by the power supply component 100, so that the atomizing medium 40 is atomized to generate an aerosol, and the nozzle 300 has a second airway 301 that runs through the two opposite ends of the nozzle 300 in the axial direction, so that the user can inhale the aerosol generated by the atomization of the atomizing medium 40 into the body through the second airway 301.
[0038] In some embodiments, the power supply assembly 100 includes a battery and an electrode. The battery includes a battery cell and a circuit board connected to the end of the battery. The battery cell is used to store the power supply medium. The circuit board is used to control the power supply of the battery cell and provide overcurrent protection for the battery cell, as well as other control logic for controlling the electronic atomizer 10. There are two electrodes, namely a positive electrode and a negative electrode. One end of each electrode is connected to the circuit board, and the other end is connected to the atomizer assembly 200, so as to form a conductive loop so as to be able to power the atomizer assembly 200.
[0039] In some embodiments, the atomizer assembly 200 includes a coaxially arranged housing 210, an atomizer core 220, and an oil storage cavity 230. One end of the housing 210 along the axial direction is plugged into the power supply assembly 100, and the atomizer core 220 and the oil storage cavity 230 are accommodated in the housing 210. The atomizer core 220 is connected to the electrode of the power supply assembly 100, and one end of the oil storage cavity 230 is connected to the atomizer core 220. The oil storage cavity 230 is filled with an atomizing medium 40 and an anti-dry burning medium 50. The atomizer core 220 can generate heat energy when the power supply component 100 is working to atomize the atomizing medium 40 and the anti-dry burning medium 50 in the oil storage cavity 230 respectively. The atomizing medium 40 is used to atomize and generate a first aerosol that simulates the feeling of smoking, and the anti-dry burning medium 50 is used to atomize and generate a second aerosol. Compared with the first aerosol, the second aerosol has at least one property that is different from that of the first aerosol so that it can be perceived by the user. The user can determine whether the atomizing medium 40 is exhausted by perceiving the different properties of the first aerosol and the second aerosol.
[0040] In one embodiment, the oil storage cavity 230 is in an inverted cone-shaped structure, and the outer diameter of one end connected to the atomizer core 220 is smaller than the outer diameter of the other end. The oil storage cavity 230 includes an oil storage cavity shell 231 and a center tube 232 inserted in the oil storage cavity shell 231. The inner wall of the oil storage cavity shell 231 and the outer wall of the center tube 232 jointly define an oil storage cavity 233 for accommodating the atomizing medium 40 and the anti-dry burning medium 50. The center tube 232 has a first air channel 2321 connected to the second air channel 301 of the suction nozzle 300. The first air channel 2321 is surrounded by the tube body of the center tube 232. The first air channel 2321 and the second air channel 301 jointly form an air flow channel with two opposite ends respectively connected to the atomizer core 220 and the external environment.
[0041] In this embodiment, the electronic atomizer 10 is an electronic cigarette, and the atomizing medium 40 used in the electronic cigarette is smoke oil. The main components of the smoke oil are propylene glycol and glycerol. The characteristics of propylene glycol and glycerol are that they can be mutually dissolved with most substances. Most substances that cannot be dissolved in propylene glycol and glycerol are also harmful to the human body. Once these harmful substances are used as the anti-dry burning medium 50, these harmful substances will also be inhaled by the human body after atomization, which is obviously not feasible. After a lot of experimental research, the inventor of this application has found a substance that is not only difficult to dissolve in smoke oil, but also has a lower density than smoke oil and is harmless to the human body as the anti-dry burning medium 50, that is, a grease that can float on the surface of the smoke oil and is difficult to dissolve in the smoke oil, such as butter and tallow. The grease has low cost, acceptable taste and is harmless to the human body, and can be solid, semi-solid or liquid. When the grease is solid or semi-solid, it can be formed through a thinning process to form a sheet-like structure and laid on the surface of the atomizing medium 40 away from the atomizing core 220; when the grease is liquid, the grease can be dropped on the surface of the atomizing medium 40 away from the atomizing core 220 to make it float on the atomizing medium 40.
[0042] In this way, when the atomizing medium 40 and the anti-dry burning medium 50 are heated and atomized, since the atomizing medium 40 is closer to the atomizing core 220 than the anti-dry burning medium 50, the atomizing medium 40 is heated and atomized before the anti-dry burning medium 50 to generate the first aerosol. When the atomizing medium 40 is consumed, the anti-dry burning medium 50 will be heated and atomized to generate the second aerosol. The first aerosol and the second aerosol generated in sequence can be inhaled by the user through the nozzle 300, so that the first aerosol and the second aerosol are inhaled into the mouth of the user through the air flow channel in sequence, and the different flavors of the first aerosol and the second aerosol are sensed in sequence to determine whether the atomizing medium 40 has been exhausted.
[0043] Preferably, in order to enable the user to more clearly perceive the difference between the first aerosol generated by the atomization medium 40 and the second aerosol generated by the atomization of the anti-dry-burn medium 50, the anti-dry-burn medium 50 can be completely covered and sealed on the surface of the atomization medium 40 away from the atomization core 220, or the thickness of the anti-dry-burn medium 50 after being compressed can be controlled so that it can generate more second aerosols and can be fully perceived by the user to distinguish the difference from the first aerosol. At the same time, the outer shell of the oil storage cavity 230 can also be optimized so that the inner diameter of the outer shell of the oil storage cavity 230 away from the atomization core 220 can better match the thickness of the anti-dry-burn medium 50 after being compressed.
[0044] It should be noted that the material of the anti-dry-burning medium 50 is not limited to grease, but can also be other insoluble media, as long as it is insoluble in the atomized medium 40 and has a density less than that of the atomized medium 40, so that the anti-dry-burning medium 50 can float on the surface of the atomized medium 40 and is harmless to the human body, and there is no specific limitation. At the same time, since the properties of the first aerosol and the second aerosol are different, they can be different in taste, color, or smell. Therefore, the way in which the user perceives the difference between the first aerosol and the second aerosol is not limited to inhaling the first aerosol and the second aerosol into the mouth in sequence. It can be judged whether the atomized medium 40 is exhausted by perceiving the difference in taste between the first aerosol and the second aerosol, or by observing the difference in color between the first aerosol and the second aerosol with the eyes or by smelling the difference in smell between the first aerosol and the second aerosol with the nose. There is no specific limitation.
[0045] In some embodiments, Figure 2As shown, the atomizing core 220 includes a heating body 221, an oil-conducting cotton 222 and a heating element 223. The opposite ends of the heating body 221 are respectively abutted against the oil storage cavity 230 and the circuit board. The oil-conducting cotton 222 and the heating element 223 are accommodated in the heating body 221. The oil-conducting cotton 222 is connected to the heating element 223, and the heating element 223 is connected to the power supply assembly 100. The oil-conducting cotton 222 is used to introduce the atomizing medium 40 or the anti-dry-burning medium 50 dripped from the oil storage cavity 233 into the heating element 223, so that the heating element 223 heats the atomizing medium 40 and the anti-dry-burning medium 50. Optionally, the heating element 223 can be a metal heating wire wound on the oil-conducting cotton 222, or a metal heating sheet arranged on the bottom wall of the heating body 221, which is not limited here.
[0046] Preferably, the atomization assembly 200 also includes an oil seepage plate 240, which is disposed between the oil storage cavity 230 and the heating element 221. The oil storage cavity 230 and the atomization core 220 are matched with each other through the oil seepage plate 240. For example, the oil seepage plate 240 can be respectively against the oil storage cavity 230 and the heating element 221 on opposite sides along the thickness direction. The oil seepage plate 240 is provided with a plurality of oil seepage holes arranged at intervals and passing through the oil seepage plate 240. In this way, the atomization medium 40 and the anti-dry burning medium 50 in the oil storage cavity 230 can drip into the heating element 221 slowly and evenly through the oil seepage holes, rather than dripping directly from the oil storage cavity 230 into the heating element 221, thereby avoiding the atomization medium 40 from suddenly dripping into the heating element 221 in large quantities to produce a thick aerosol and choke the user, and also avoiding the occurrence of safety hazards.
[0047] The following combination Figure 1 and Figure 2 , the method of using the anti-dry burning electronic atomizer provided in this application is further introduced.
[0048] The first step is to power on the anti-dry-burn electronic atomizer so that the atomizing medium 40 in the atomizing assembly 200 is atomized before the anti-dry-burn medium 50 in the atomizing assembly 200 is atomized.
[0049] Specifically, in this step, the atomizing medium 40 needs to be atomized first to reduce the volume of the atomizing medium 40 so that the anti-dry burning medium 50 is close to the atomizing core 220 of the atomizer; and then the anti-dry burning medium 50 is atomized.
[0050] As described above, since the anti-dry burning medium 50 is insoluble in the atomizing medium 40 and has a lower density than the anti-dry burning medium 50, the anti-dry burning medium 50 can float on the surface of the atomizing medium 40, and since the atomizing core 220 is disposed at the bottom of the oil storage cavity 230, the atomizing medium 40 is closer to the atomizing core 220 than the anti-dry burning medium 50. Therefore, when the atomizing core 220 begins to generate heat, the atomizing medium 40 must be heated and atomized before the anti-dry burning medium 50. After the atomizing medium 40 is heated and atomized, the volume of the atomizing medium 40 decreases, and the liquid level of the atomizing medium 40 gradually decreases, so that the anti-dry burning medium 50 gradually approaches the atomizing core 220, until the atomizing medium 40 is exhausted, and the anti-dry burning medium 50 contacts the atomizing core 220 and is atomized, thereby generating different atomization states according to the order in which the atomizing medium 40 and the anti-dry burning medium 50 are atomized.
[0051] In the second step, different atomization states are obtained according to the order of atomization of the atomization medium 40 and the anti-dry burning medium 50 to determine whether the atomization medium 40 is exhausted. The atomization state includes a first atomization state and a second atomization state, so that heating the atomization medium 40 can generate a first aerosol, so that the atomizer has a first atomization state. Heating the anti-dry burning medium 50 can generate a second aerosol, so that the atomizer has a second atomization state. The user determines whether the atomization medium 40 is exhausted by sequentially perceiving the difference between the first aerosol and the second aerosol.
[0052] Specifically, the first aerosol and the second aerosol can be inhaled into the mouth, and the atomized medium 40 can be judged to be exhausted by judging the difference in their tastes. Alternatively, the atomized medium 40 can be judged to be exhausted by observing the difference in color between the first aerosol and the second aerosol with the eyes or smelling the difference in the smell between the first aerosol and the second aerosol with the nose. When the user perceives the difference between the first aerosol and the second aerosol in the above manner, it can be judged that the atomized medium 40 has been exhausted, and the user stops inhaling, thereby achieving the purpose of preventing dry burning.
[0053] In this way, the above-mentioned anti-dry-burn electronic atomizer utilizes the low-cost and easily available anti-dry-burn medium 50 to float on the surface of the atomizing medium 40, and sets the atomizing core 220 at the bottom of the atomizing medium 40 to keep the anti-dry-burn medium 50 away from the atomizing core 220, so that the atomizing medium 40 is necessarily heated and atomized before the anti-dry-burn medium 50. The user can judge whether the atomizing medium 40 is exhausted by sensing the changes in the first aerosol generated by the atomization of the atomizing medium 40 and the second aerosol generated by the atomization of the anti-dry-burn medium 50. Without the aid of a sensor, the atomizing core 220 can be prevented from continuing to dry-burn after the atomizing medium 40 is exhausted. Regardless of whether the atomization temperature of the atomizing medium 40 is consistent, the purpose of preventing dry-burning can be achieved without causing misjudgment.
[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
