[0036] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Figure 1Some preferred embodiments of the electronic atomizing device of the present invention are shown. This electronic atomizing device can be used to heat and atomize a liquid matrix to generate atomized gas for the user to inhale. In some embodiments, the liquid matrix is ​​a liquid aerosol generating matrix. This electronic atomizing device can greatly improve the problem of burnt smells during inhalation, and has the advantages of being less prone to burnt smells and providing a superior user experience.

[0038] Furthermore, in this embodiment, the electronic atomizing device includes an atomizer 1 and a power supply component 2; the atomizer 1 can be used to atomize liquid aerosol to generate a matrix, and the power supply component 2 can be mechanically and electrically connected to the atomizer 1 and can be used to supply power to the atomizer 1.

[0039] like Figures 2 to 5 As shown, the atomizer 1 includes an atomizing shell 10, a base 20, an atomizing seat 30, a heating element 40, and a liquid storage structure 50. The atomizing shell 10 can be cylindrical with a hollow inner structure for housing the atomizing seat 30 and the heating element 40, and for storing the liquid matrix. The base 20 is assembled with the atomizing seat 30 and is used to connect the power supply component 2. The atomizing seat 30 is sleeved on the base 20 and is detachably connected to the base 20, for housing the heating element 40. The heating element 40 is disposed in the atomizing seat 30 and is used to heat the liquid matrix transmitted from the atomizing shell 10. The liquid storage structure 50 is disposed in the atomizing seat 30 and is fluidly connected to the liquid storage chamber 13 in the atomizing shell 10 and the heating element 40. It is used to store the liquid matrix and can supply liquid to the heating element 40, so that the heating element 40 is always fully filled, avoiding insufficient liquid supply and causing a burnt taste during inhalation, thereby improving the aerosol volume and inhalation experience to a certain extent.

[0040] Further, in this embodiment, the atomizing shell 10 includes a shell 11 and an outlet pipe 12 disposed within the shell 11. The outlet pipe 12 may be located at the central axis of the shell 11 and extend to the atomizing seat 30. The gap between the outlet pipe 12 and the inner wall of the shell 11 can form a liquid storage chamber 13 for storing the liquid aerosol generation matrix. The shell 11 has two ends in its axial direction, one end of which is provided with an assembly port 111 and the other end is provided with an outlet 112. The assembly port 111 communicates with the liquid storage chamber 13 for assembling the atomizing seat 30. The outlet 112 communicates with the outlet pipe 12 for outputting the aerosol formed after atomization.

[0041] Further, in this embodiment, the base 20 includes a seat body 21, the cross-section of which may be approximately circular. The atomizing shell 10 can be fitted onto the seat body 21 and can be interference-fitted with the seat body 21. The power supply component 2 can be inserted into the seat body 21 from the end of the seat body 21 opposite to the atomizing shell 10, and then connected to the seat body 21. In this embodiment, an air intake channel 211 is provided at the central axis of the seat body 21, which is used to allow external gas to enter the atomizer 1, thereby carrying out the aerosol generated by atomization. The seat body 21 is provided with two hooks 22 that engage with the atomizing seat 30. The two hooks 22 are spaced apart and can be inserted into the atomizing seat 30 and engage with the atomizing seat 30.

[0042] See also Figures 3 to 7 Further, in this embodiment, the atomizing base 30 includes a body 31 and a receiving portion 32. The body 31 has a generally circular cross-section. The body 31 includes a cylindrical body 311 and a mating portion 312 located at one end of the cylindrical body 311. The cylindrical body 311 may be generally cylindrical, and one end is provided with a sleeve interface 3111, and it is hollow, with an atomizing cavity 3110 formed inside. The cross-sectional shape and size of the cylindrical body 311 are adapted to the cross-sectional shape and size of the atomizing shell 10, and it can be interference-fitted with the atomizing shell 10. The mating portion 312 is located at one end of the cylindrical body 311, and its cross-sectional size is smaller than that of the cylindrical body 311, and it can be used to mate with the second sealing member 70. The receiving portion 32 is disposed in the cylindrical body 311 and is used to accommodate the heating element 40.

[0043] Further, in this embodiment, the receiving portion 32 includes a top wall 321 and a plurality of side walls 322; the top wall 321 and the plurality of side walls 322 surround a receiving cavity 320 with an opening 323. In this embodiment, there are four side walls 322. The cross-section of the receiving cavity 320 is generally square. The opening 323 is disposed toward the socket of the atomizing seat 30. The receiving cavity 320 can accommodate at least a portion of the heating element 40.

[0044] Furthermore, in this embodiment, the atomizing seat 30 also includes an atomizing port 33, which is formed on the mating part 312, located at the central axis of the mating part 312, and can communicate with the air outlet pipe 12. The atomizing seat 30 also includes two liquid outlets 34, which are disposed on the mating part 312 and on opposite sides of the atomizing port 33. A liquid channel 341 is formed inside the liquid outlet 34, which communicates with the receiving cavity 320. Specifically, the liquid channel 341 can extend to the top wall of the receiving part 32 and communicate with the receiving cavity 320. In this embodiment, the atomizing base 30 is also provided with a connecting channel 35, which is located on the side wall of the atomizing base 30 and is used to connect the atomizing chamber 3110 and the atomizing port 33, so that the aerosol formed by atomization in the atomizing chamber 3110 can be output to the atomizing port 33 and output from the atomizing port 33 to the air outlet pipe 12.

[0045] Furthermore, in this embodiment, the heating component 40 includes a porous body 41. The porous body 41 may be cuboid in shape and may be partially embedded in the receiving cavity 320. Of course, it is understood that in other embodiments, the porous body 41 may not be limited to a cuboid shape, but may be columnar or other shapes. In this embodiment, the porous body 41 is a ceramic porous body; it is understood that in other embodiments, the porous body 41 is not limited to a ceramic porous body, and may be cotton or other materials.

[0046] Specifically, in this embodiment, the porous body 41 includes a first liquid-absorbing surface 411, an atomizing surface 412, and a second liquid-absorbing surface 413. The first liquid-absorbing surface 411 can be located on the side of the porous body 41 opposite to the top wall 321 of the receiving portion 32, and opposite to the liquid-lowering channel 341, and can directly absorb the liquid matrix directly discharged from the liquid-lowering channel 341. The atomizing surface 412 is disposed opposite to the first liquid-absorbing surface 411, and the atomizing surface 412 is the end face of the heating element 42. There are four second liquid-absorbing surfaces 413, two of which are disposed between the first liquid-absorbing surface 411 and the atomizing surface 412, and can absorb the liquid matrix from the liquid storage structure 50. It can be understood that in some other embodiments, the number of second liquid-absorbing surfaces 413 is not limited to two, but can be three or four.

[0047] In this embodiment, the heating component 40 further includes a heating element 42, which is disposed on the end face of the porous body 41 opposite to the first liquid absorption surface 411, thereby forming an atomizing surface 412 on the end face. In this embodiment, the heating element 42 can be a heating film. Of course, it is understood that in some other embodiments, the heating element 42 is not limited to a heating film, but can be a heating sheet or a heating wire. The heating element 42 can heat the liquid matrix absorbed in the porous body 41 when energized.

[0048] In this embodiment, the liquid storage structure 50 is disposed in the accommodating cavity 320 and located inside the two oppositely disposed sidewalls 322 of the accommodating cavity 320. It is opposite to the heating element 40 and is fluid-conducting. Specifically, there are two sets of liquid storage structures 50, which are respectively located on two opposite sides of the heating element 40, and each set of liquid storage structures 50 is opposite to a second liquid absorption surface 413. Of course, it is understood that in some other embodiments, the liquid storage structure 50 may also be one set, or the liquid storage structure 50 may be more than two sets. By setting the liquid storage structure 50, liquid matrix can be stored and liquid can be supplied to the heating element 40. Specifically, when the liquid storage chamber 13 outputs liquid matrix to the porous body 41 through the liquid discharge channel 341, the liquid matrix on the porous body 41 can be guided from the second liquid absorption surface 413 to the liquid storage structure 50 and temporarily stored by the liquid storage structure 50. When the liquid matrix in the porous body 41 is consumed too quickly due to the output of a large amount of aerosol and it takes a certain amount of time for the liquid matrix to flow from the first liquid absorption surface 411 to the heating element 42, so that continuous suction will cause the porous body 41 to have a significant insufficient liquid supply, and / or the porous body 41 cannot absorb enough liquid matrix due to occasional poor ventilation, the liquid storage structure 50 can supply liquid matrix to the porous body 41. The liquid matrix can be drawn into the porous body 41 through the second liquid absorption surface 413 and flow to the atomizing surface 412, and is heated by the heating element 42 to form an aerosol. The liquid storage structure 50 can greatly improve the problem of drawing out burnt smells. It can provide a liquid matrix to the porous body 41 instead of condensate when the liquid supply is insufficient, and it can keep the porous body 41 in a full state, thereby increasing the amount of aerosol to a certain extent.

[0049] In this embodiment, each liquid storage structure 50 is integrally formed in the atomizing base 30. It is understood that in other embodiments, the liquid storage structure 50 may also be detachably installed in the atomizing base 30. The liquid storage structure 50 includes multiple micro-grooves 51, which are integrally formed on the sidewall 322. They can absorb and store liquid matrix through capillary action. During atomization, if the liquid supply is not timely or the ventilation is abnormal, the stored liquid matrix will be absorbed by the capillary force of the porous body 41, thereby continuously providing liquid matrix to the heating element 42, avoiding low aerosol volume, burnt taste, and reduced flavor. The multiple micro-grooves 51 are spaced apart along the length of the sidewall 322. The opening of each micro-groove 51 is at least partially opposite to the heating element 40 and is fluidly connected to the heating element 40. Specifically, the opening of each micro-groove 51 is opposite to and fluidly connected to the second liquid absorption surface 413, and each micro-groove 51 extends towards the opening 323. In this embodiment, the microgroove 51 may be triangular. It is understood that in some other embodiments, the microgroove 51 is not limited to multiple microgrooves, but may be a single microgroove; in some embodiments, the microgroove 51 may be omitted altogether. In other embodiments, the microgroove 51 is not limited to a triangular shape, but may be circular, trapezoidal, rectangular, or irregular in shape, etc., as long as it is a structure capable of storing or allowing a liquid matrix to remain temporarily.

[0050] In this embodiment, by setting the liquid storage structure 50 opposite to the second liquid absorption surface 413, the liquid guiding surface of the porous body 41 is increased, thereby improving the continuity of liquid supply to the heating element 42. This avoids the problem of untimely liquid supply caused by relying solely on the first liquid absorption surface 411 for liquid guiding, and also avoids the generation of burnt smell, especially when atmospheric fog and ventilation are not smooth.

[0051] In this embodiment, the atomizer 1 further includes a first sealing member 60, which is a silicone component and may be square-shaped. The first sealing member 60 is disposed between the porous body 41 and the top wall 321 of the receiving portion 32, for sealing the gap between the first liquid-absorbing surface 411 of the porous body 41 and the top wall 321. Of course, it is understood that in some other embodiments, the first sealing member 60 may not be limited to a silicone component, and may not be limited to being disposed between the porous body 41 and the top wall 321 of the receiving portion 32.

[0052] In this embodiment, the atomizer 1 further includes a second sealing element 70. The second sealing element 70 can be a sealing sleeve, which can be fitted onto the mating part 312 to seal the connection between the atomizing seat 30 and the atomizing shell 10. In this embodiment, the second sealing element 70 is provided with a first through hole 71 corresponding to the atomizing port 33 and a second through hole 72 corresponding to the liquid outlet 34. The first through hole 71 communicates with the atomizing port 33. The second through hole 72 communicates with the liquid outlet 34.

[0053] In this embodiment, the atomizer 1 further includes a conductive element 80. There can be two conductive elements 80, which are spaced apart on the base 20. One end of each conductive element 80 is in contact with the heating element 42, and the other end can be connected to the power supply component 2 to connect the power supply component 2 and the heating element 42.

[0054] Figures 8 to 9 A second embodiment of the electronic atomizing device of the present invention is shown, which differs from the first embodiment in that the liquid storage structure 50 can be an independent component. The liquid storage structure 50 is detachably installed in the accommodating cavity 320 and is arranged opposite to the heating component 40.

[0055] Specifically, each liquid storage structure 50 includes a liquid storage element 52, which is detachably installed in the accommodating cavity 320 and located between the porous body 41 and the sidewall 322, i.e., opposite to the heating element 40. The liquid storage element 52 may be generally cuboid in shape. In this embodiment, a plurality of microgrooves 51 are formed on the side of the liquid storage element 52 opposite to the heating element, and the plurality of microgrooves 51 are spaced apart along the length of the liquid storage element 52. The opening of each microgroove 51 is at least partially opposite to the heating element 40, thereby allowing fluid communication with the heating element 40. Specifically, each micro-channel 51 can be rectangular, with its opening positioned opposite to the second liquid-absorbing surface 413 and in fluid communication with the second liquid-absorbing surface 413. It can absorb and store liquid matrix from the second liquid-absorbing surface 413, and output liquid matrix to the second liquid-absorbing surface 413 in the event of untimely liquid supply or abnormal ventilation. The second liquid-absorbing surface 413 absorbs the liquid matrix from the micro-channel 51 through capillary force and provides liquid matrix to the heating element 42, thus avoiding low suction mist volume, burnt taste, and reduced taste.

[0056] In this embodiment, the liquid storage structure 50 can be a porous structure, which can increase the liquid storage capacity and make it easier to store liquid matrix. Specifically, the liquid storage element 52 can be absorbent cotton. Of course, it is understood that in some other embodiments, the liquid storage structure 50 is not limited to cotton, but can also be silicone or metal. The liquid storage structure 50 can absorb excess liquid matrix on the porous body 41 by capillary action. When the liquid supply is insufficient, the stored liquid matrix can be absorbed by the capillary action of the porous body 41, avoiding insufficient liquid supply leading to small aerosol volume, burnt taste, and reduced taste.

[0057] In some other embodiments, the liquid storage structure 50 may extend partially to the atomizing surface 412, that is, the liquid storage element 52 may extend partially to the atomizing surface 412, and the longitudinal section of the liquid storage element 52 may be approximately L-shaped, and the microgroove 51 may also be approximately L-shaped. It is understood that in some other embodiments, the liquid storage structure 50 may also extend partially to the first liquid absorption surface 411, that is, the liquid storage element 52 may extend partially to the first liquid absorption surface 411.

[0058] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
