[0002] The core component of the atomizer is the atomization chamber that heats and atomizes liquids such as e-liquids and liquid medicines to generate aerosols, and the function of the atomizer is mainly based on the liquid-conducting and heating structure arranged in the atomization chamber. This liquid-conducting and heating structure usually has a porous body for absorbing and conducting liquids, and a heating element arranged on the porous body for heating and atomizing the liquid absorbed and conducted by the porous body.

However, research has found that the aerosol particles produced by the atomizer using the ceramic core are uneven in size, which makes the aerosol taste poor, and the ceramic core is easily powdered and causes powder loss due to repeated thermal cycles and liquid erosion, which is harmful to human health; the aerosol particles produced by the atomizer using the cotton core are also uneven in size, and the atomized particles are relatively large, and are prone to oil leakage, and even easy to burn the cotton core and cause the core to become sticky. Summary of the invention

DETAILED DESCRIPTION

[0025] For ease of understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on another element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to another element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0027] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] In this specification, the term "installation" includes fixing or restricting a component or device to a specific position or place by welding, screwing, clamping, bonding, etc. The component or device may remain stationary at the specific position or place or move within a limited range. After being fixed or restricted to a specific position or place, the component or device may or may not be disassembled, which is not limited in the embodiments of the present invention.

[0029] See also Figures 1 to 3 , which shows a liquid-conducting and heating structure 100 provided in an embodiment of the present invention. The liquid-conducting and heating structure 100 may mainly include an aerosol dispensing component 10, a heating component 20 and a liquid absorbing component 30.

[0030] The aerosol dispenser 10 has a first surface 11 and a second surface 12 opposite to the first surface 11, and has a plurality of aerosol dispensing through holes 13 penetrating the first surface 11 and the second surface 12; that is, the plurality of aerosol dispensing through holes 13 penetrate the aerosol dispenser 10 from the first surface 11 to the second surface 12. The heating element 20 is disposed adjacent to the first surface 11 and is used to generate heat when powered on; for example, the heating element 20 may be disposed in contact with or in close contact with the first surface 11, or the heating element 20 may be spaced apart from the first surface 11, as long as it is disposed on the side close to the first surface 11. The liquid absorbing element 30 is disposed on the heating element 20 and is used to absorb liquid and transport the absorbed liquid to the vicinity of the heating element 20. The liquid absorbing member 30 may have good wetting properties for liquid, and may evenly distribute the liquid in the pores of the liquid absorbing member 30 through, for example, capillary action, so as to have liquid absorption capacity; further, since the liquid in the liquid absorbing member 30 tends to be evenly distributed, when the liquid in the portion of the liquid absorbing member 30 close to the heating element 20 is atomized and consumed, the liquid in other portions of the liquid absorbing member 30 may be transported toward the vicinity of the heating element 20. The liquid may be, for example, a liquid that can be heated and atomized, such as tobacco oil, liquid medicine, etc.

[0031] In this embodiment, the liquid-conducting heating structure 100 adopts an aerosol distribution component 10, a heating component 20 and a liquid absorption component 30 which are arranged in sequence, and a plurality of aerosol distribution through holes 13 are arranged on the aerosol distribution component 10, so that when the heating component 20 is powered on, it generates heat to heat and atomize the liquid transported by the liquid absorption component 30, and then the aerosol is emitted from these aerosol distribution through holes 13 in a controlled manner. This arrangement can make the atomized smoke particles uniform and fine.

[0032] In some embodiments, the aerosol distribution component 10 may be a dense ceramic body, and the aerosol distribution through hole 13 is a through hole perpendicular to the second surface 12. The dense ceramic body can be made of materials such as silicon carbide, aluminum nitride or aluminum oxide. Since dense ceramic materials are used, the aerosol distribution component 10 needs to be provided with through holes to pass the aerosol, and the dense ceramic body will not leak gas or liquid except for these through holes. These aerosol distribution through holes 13 can be made by mechanical drilling, laser punching, etc., or can be integrally molded or 3D printed with the aerosol distribution component 10. In addition, the liquid absorbent 30 can be a multi-gap body, and the multi-gap body has multiple liquid delivery gaps. For example, the liquid absorbent 30 can be a porous ceramic or glass fiber material, so that the internal pore structure of the porous ceramic or glass fiber material can be used to generate a capillary phenomenon, thereby achieving liquid absorption and delivery.

[0033] In some embodiments, the aerosol distribution member 10 may be a zirconium oxide sheet, such as a high-density zirconium oxide sheet; the aerosol distribution through hole 13 is a through hole perpendicular to the second surface 12. Zirconia is a dense ceramic material. In this embodiment, the aerosol distribution member 10 is made of sheet-shaped zirconium oxide; similarly, these aerosol distribution through holes 13 can be made by mechanical drilling, laser drilling, etc., or can be integrally molded or 3D printed with the aerosol distribution member 10. In addition, the liquid absorbent member 30 can be a liquid absorbent cotton; for example, the liquid absorbent member 30 can be a sheet-shaped cotton or cotton cloth, which has good wetting properties for liquid and can make the liquid evenly distributed in the pores of the liquid absorbent member 30 through capillary action. By using a combination of liquid absorbent cotton and zirconium oxide sheets, the problems of poor taste, easy powder loss, and great harm to human health caused by the use of a ceramic core alone can be effectively solved, and the problems of large atomized particles, easy oil leakage, and easy core sticking caused by the use of a cotton core alone can also be effectively solved.

[0034] In this embodiment, by arranging the zirconium oxide sheet, the sheet heating element and the liquid absorbent cotton in an overlapping manner, the support requirements for the shell for accommodating the zirconium oxide sheet, the sheet heating element and the liquid absorbent cotton are not high, and are not restricted by shape, which facilitates product structural design. For example, the product can be made smaller in size, thereby improving the space utilization of the product.

[0035] In some embodiments, the aerosol dispenser 10 is a sheet, and the heating element 20 may include a heating sheet, so that the sheet-shaped aerosol dispenser 10 is conveniently placed in close contact with the heating sheet of the heating element 20. It is noted that the heating sheet described herein means that the heating circuit of the heating element 20 can be arranged in the same plane, for example, the heating sheet can be a heating circuit arranged in a zigzag manner, a heating circuit arranged in a grid shape, etc. Further, as Figures 1 to 3 As shown, the liquid-conducting heating structure 100 may further include a pressing plate 40, and the pressing plate 40 is pressed on the liquid-absorbing member 30. For example, when liquid-absorbing cotton is used, the pressing plate 40 can be used to firmly press the liquid-absorbing cotton, the heating member 20 and the aerosol dispensing member 10 to avoid the loosening phenomenon caused by the liquid-absorbing cotton being too fluffy. It is easy to understand that the pressing plate 40 can adopt any structure that can press the liquid-absorbing member 30, and it can also have a liquid through hole 41 to transport the liquid to the liquid-absorbing member 30 through the liquid through hole 41. In the illustrated embodiment, the middle part of the pressing plate 40 is hollowed out to form the liquid through hole 41.

[0036] In a further embodiment, Figures 1 to 3As shown, the liquid-conducting heating structure 100 may also include a receiving shell 50, which may be cylindrical and have a receiving cavity 51. The receiving cavity 51 may have a first opening 52 and a second opening 57 opposite thereto. The aerosol dispensing component 10, the heating component 20, the liquid absorbing component 30 and the pressing plate 40 are sequentially arranged in the receiving cavity 51, and the second surface 12 of the aerosol dispensing component 10 is exposed through the first opening 52 of the receiving cavity 51. Since the second surface 12 of the aerosol dispensing component 10 is exposed through the first opening 52, when the heating component 20 is powered on, the liquid transported by the liquid absorbing component 30 is heated and atomized, and the generated aerosol can be emitted from these aerosol dispensing through holes 13 through the first opening 52, so as to be further delivered to the user for inhalation. In addition, by adopting the containing shell 50 to load the aerosol distribution component 10, the heating component 20, the liquid absorption component 30 and the pressing plate 40 therein, the structure is simple and compact. One end of the cylindrical containing shell 50 is set as the liquid inlet end, and the other end is set as the atomization end. The airway and the liquid to be atomized are separated from each other, and the atomized smoke is carried thoroughly. On the other hand, the sheet-type heating component 20 and the liquid are isolated by the liquid absorption component 30, so that the heat diffusion is small and the heat utilization rate is high.

[0037] In a further embodiment, Figure 2 and Figure 3 As shown, the aerosol dispenser 10 may also have two lead wire insertion holes 14. The heating element 20 also includes two lead wires 21; during assembly, the aerosol dispenser 10 may be first installed in the receiving shell 50, and then the two lead wires 21 may be respectively aligned with the two lead wire insertion holes 14 and inserted through the two lead wire insertion holes 14 and extend out of the first opening 52 of the receiving cavity 51.

[0038] In a further embodiment, Figure 2 and Figure 3 As shown, the receiving shell 50 has a first stopper 53 defining the first opening 52, and the aerosol dispenser 10 can be placed against the first stopper 53; and the receiving shell 50 can also have a second stopper 54, and the pressing plate 40 can be placed against the second stopper 54. The first stopper 53 can be a step or platform extending toward the first opening 52, so as to receive the aerosol dispenser 10 and limit its downward movement; similarly, the second stopper 54 can be a step or platform extending toward the inside of the receiving shell 50, so as to receive the pressing plate 40 and limit its downward movement. By providing the first stopper 53 and the second stopper 54, the assembly of the aerosol dispenser 10, the heating element 20, the liquid absorbing element 30 and the pressing plate 40 is more convenient.

[0039] In a further embodiment, Figure 2As shown, the receiving chamber 51 may include a first space 55 and a second space 56. The first space 55 may be used to receive the aerosol dispenser 10, the heating element 20, the liquid absorbent 30 and the pressing plate 40, and the second space 56 may be used to contain liquid. In other words, the portion of the receiving chamber 51 that receives the aerosol dispenser 10, the heating element 20, the liquid absorbent 30 and the pressing plate 40 is the first space 55, and the portion other than the first space 55 is the second space 56. When the receiving chamber 51 has the second space 56, more liquid can be stored, so that when the liquid absorbed in the liquid absorbent 30 is consumed, the liquid in the second space 56 can be replenished to the liquid absorbent 30.

[0040] In some embodiments, the aperture of the aerosol distribution through hole 13 can be any value in the range of 5μm to 100μm, for example, 5μm, 5.5μm, 6μm, 10μm, 15μm, 30μm, 50μm, 60μm, 90μm, 100μm, etc.; the apertures of the multiple aerosol distribution through holes 13 can be the same or slightly different. In addition, the multiple aerosol distribution through holes 13 can be evenly distributed, for example, they can be distributed in a matrix form. Since the multiple aerosol distribution through holes 13 are micropores, when the heating element 20 heats and atomizes a liquid such as tobacco oil, the smoke will evaporate through the micropores on the aerosol distribution element 10, so that the atomized smoke particles can be very fine and there will be no oil explosion problem.

[0041] like Figure 4 As shown, the present invention further provides an atomization chamber 200, which may include a housing assembly 70 and any one of the above-described liquid-conducting and heating structures 100. The housing assembly 70 defines an atomization channel 71, and the liquid-conducting and heating structure 100 is at least partially located in the atomization channel 71.

[0042] In some embodiments, the shell assembly 70 may be a hollow outer shell, and its lower end may be open, and the atomization channel 71 in the shell assembly 70 may be arranged along the axial direction of the shell assembly 70. The atomization channel 71 may include an atomization cavity 72, that is, the part of the atomization channel that accommodates the liquid-conducting and heating structure 100. The upper end of the atomization channel 71 is used to communicate with the suction nozzle, so that the aerosol generated by the internal liquid-conducting and heating structure 100 is output to the suction nozzle at the upper end of the shell assembly 70 for inhalation. A liquid storage cavity 73 for storing liquid may be further formed between the outer wall of the atomization channel 71 and the inner wall of the shell assembly 70. A silicone seat 74 located at the lower end of the liquid storage cavity 73 may also be installed in the shell assembly 70. The silicone seat 74 is mainly used to close the liquid storage cavity 73 to prevent liquid leakage, and on the other hand, it can be used as a carrier to provide a base for the installation of the liquid-conducting and heating structure 100. The open end of the shell assembly 70 may also be provided with an end cap 75, and the atomization chamber 72 is formed between the end cap 75 and the silicone seat 74, and the atomization chamber 72 is configured as a space for atomizing the liquid after the liquid-conducting and heating structure 100 is installed. A liquid-conducting hole 76 for conducting the liquid from the liquid storage chamber 73 to the liquid-conducting and heating structure 100 may be provided in the silicone seat 74, and one end of the liquid-conducting hole 76 is connected to the liquid storage chamber 73, and the other end is connected to the second space 56 of the liquid-conducting and heating structure 100. At the same time, the two leads 21 of the liquid-conducting and heating structure 100 can pass through the end cap 75 as electrode columns or be electrically connected to the electrode columns in the end cap 75, so that the liquid-conducting and heating structure 100 can be powered.

[0043] Refer to Figure 5 As shown, the present invention further provides an atomizer 400 , which may include a power supply component 300 and the atomization bin 200 described above, wherein the power supply component 300 is used to supply power to the atomization bin 200 .

[0044] In some embodiments, the lower end of the atomization bin 200 can be detachably connected to the upper end of the power supply component 300 by plugging and unplugging. For example, the lower end of the atomization bin 200 can be set as an insertion portion, and the upper end of the power supply component 300 can be provided with a socket, so that the insertion portion can be inserted into the socket to form an atomizer 400. Furthermore, a magnet may be included at the lower end of the atomization bin 200, and a magnet may also be correspondingly arranged in the socket of the power supply component 200, so that the atomization bin 200 and the power supply component 300 can be assembled by magnetic attraction. In other embodiments, the atomization bin 200 and the power supply component 300 can also be assembled by means of snap-fitting, threaded connection, etc., which can also make the two disassembled.

[0045] Combination Figure 4 and Figure 5As shown, when the atomizer 400 is working, the power supply component 300 transmits current to the heating element 20 of the liquid-conducting heating structure 100, so that the heating circuit of the heating element 20 heats up; the liquid is transmitted from the liquid storage chamber 73 to the second space 56 of the liquid-conducting heating structure 100 through the liquid conducting hole 76, and is further transmitted to the heating element 20 through the micropores of the liquid absorption component 30, and is atomized to generate an aerosol, and then escapes into the atomization chamber 72 through the aerosol distribution component 10; the airflow circulation process is that the user inhales the negative pressure generated by the suction nozzle at the upper end of the atomization channel 71, thereby driving the external airflow to enter the atomization chamber 72 from the air inlet 77 at the lower end of the atomization channel 71, and then carries the aerosol in the atomization chamber 72 together and outputs it to the suction nozzle at the upper end of the atomization channel 71 to be inhaled, forming a complete airflow circulation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they may still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
