[0009] In some embodiments, the atomizer further includes a base unit having a receiving cavity, the liquid absorption unit being disposed within the receiving cavity, and the air intake column being formed on the base unit and extending toward the interior of the receiving cavity; the base unit also has an air outlet, and the air guiding space is connected to the atomization channel through the air outlet; the cross-sectional dimension of the air guiding hole is larger than the cross-sectional dimension of the air outlet.

[0010] In some embodiments, the first top surface is located within the receiving cavity, and the first suction member has a second top surface facing away from the bottom surface of the receiving cavity, the second top surface being lower than the first top surface.

[0030] The directional terms "vertical," "horizontal," "above," and "below" mentioned in the text can be found in [reference]. Figure 2 Understanding the directions indicated in the diagram. In the diagram, U represents the up direction, D represents the down direction, UD represents the vertical direction; L represents the left direction, R represents the right direction, and LR represents the horizontal direction.

[0031] In some embodiments, this application provides an electronic atomizing device, which includes a power supply unit (not shown) and an atomizer, the atomizer and the power supply unit being connected. Specifically, the atomizer and the power supply unit can be detachably connected or are an integrated structure. The power supply unit provides power to the atomizer. The power supply unit may include components such as a rechargeable battery. When powered on, the atomizer heats and atomizes the atomizing matrix to generate an aerosol for the user to inhale.

[0032] Please see Figure 1 and Figure 2In some embodiments, this application provides an atomizer, which includes at least an atomization channel 10, a liquid intake unit 2, and at least one air intake column 3. The atomization channel 10 is used to deliver aerosol to the outside. Specifically, a liquid storage chamber 11 is formed inside the atomizer, and the liquid storage chamber 11 stores a liquid atomizing matrix. The atomizer also includes an atomizing core 12 disposed within the atomization channel 10. The atomizing core 12 and the liquid storage chamber 11 are in liquid-conducting communication. The atomizing core 12 is connected to a power supply unit. The atomizing core 12 is used to heat and atomize the atomizing matrix from the liquid storage chamber 11 when energized. After the atomizing matrix is ​​heated and atomized, an aerosol is generated in the atomization channel 10. One end of the atomization channel 10 is in communication with the atmosphere, and the aerosol is delivered to the outside of the atomizer for the user to inhale through the atomization channel 10. Specifically, the atomizing core 12 includes a liquid guide 121 and a heating element 122. The liquid guide 121 has an inlet surface and an atomizing surface, with the inlet surface facing the liquid storage chamber 11 and the atomizing surface facing away from the liquid storage chamber 11. A heating element 122 is disposed on the atomizing surface and can be at least partially embedded in the liquid guide 121. The heating element 122 is connected to a power supply unit. The atomizing matrix within the liquid storage chamber 11 can gradually permeate from the inlet surface to the atomizing surface, and the heating element 122, when energized, heats and atomizes the atomizing matrix that has permeated to the atomizing surface.

[0033] The number of intake columns 3 can be one or more. See also Figure 2 and Figure 5 Each air intake column 3 has a first top surface 31 and an outer peripheral surface 32, and is provided with at least one air intake hole 30, which penetrates the first top surface 31. Specifically, the air intake hole 30 penetrates the air intake column 3 vertically, and the end of the air intake hole 30 away from the first top surface 31 (the air intake end) along its extension direction is connected to the atmospheric environment outside the atomizer. The liquid suction unit 2 forms an air guiding space 20, which is connected to the air intake hole 30 and the atomization channel 10 respectively. Thus, under the suction force of the user on the atomizer, external air flows sequentially through the air intake hole 30, the air guiding space 20 and the atomization channel 10, mixes with the aerosol in the atomization channel 10 and is delivered to the user's mouth. At the same time, the liquid suction unit 2 at least partially surrounds the outer peripheral surface 32 of the air intake column 3 and does not contact the first top surface 31. That is, the liquid suction unit 2 can be partially or completely surrounding the outer peripheral surface 32 of the air intake column 3. The liquid suction unit 2 is always completely out of contact with the first top surface 31.

[0034] Since the air-guiding space 20 formed by the liquid-absorbing unit 2 is connected to the air inlet 30 and the atomization channel 10 respectively, the liquid-absorbing unit 2 can be used to absorb the liquid dripping from the atomization channel 10 (mainly including condensate and atomization matrix seeping from the atomization core 12), and also provide the air-guiding space 20 to transport airflow. Therefore, the same liquid-absorbing unit 2 can be used as two functional components at the same time, eliminating the need to design an additional air inlet channel, thereby saving internal space of the device and helping to meet the requirements of leakage prevention and air intake at the same time when the device size is small. At the same time, since the air inlet 30 penetrates the first top surface 31 of the air inlet column 3, the liquid-absorbing unit 2 is at least partially surrounded by the outer peripheral surface 32 of the air inlet column 3 and does not contact the first top surface 31. That is, the plane where the liquid-absorbing unit 2 and the air inlet 30 are located do not contact each other, thereby reducing the risk of leakage caused by the liquid stored in the liquid-absorbing unit 2 creeping to the air inlet 30.

[0035] Please see Figures 2 to 5 In some embodiments, the atomizer further includes a base unit 4. The base unit 4 forms a receiving cavity, and the liquid suction unit 2 is disposed within the receiving cavity. An air intake column 3 is formed on the base unit 4 and extends toward the interior of the receiving cavity. The air intake column 3 and the base unit 4 can be an integrally formed structure or they can be independent structures. The first top surface 31 is located inside the receiving cavity. The air outlet of the air inlet 30 is located inside the receiving cavity; the air inlet port of the air inlet 30 is located outside the receiving cavity, at the bottom of the base unit 4, and is connected to the outside atmosphere. The base unit 4 also has an air outlet 40, and the air guiding space 20 is connected to the atomization channel 10 through the air outlet 40. That is, under the suction force of the user on the atomizer, external air flows sequentially through the air inlet 30, the air guiding space 20, the air outlet 40, and the atomization channel 10. The air outlet 40 and the air inlet 30 are staggered. Specifically, the air outlet 40 and the air inlet 30 are offset laterally, and their vertical projections do not overlap at all. As a result, when condensate generated in the atomization channel 10 or liquid such as the atomization matrix seeping from the atomization core 12 drips from the air outlet 40, the liquid will not drip vertically to the position of the air inlet 30, but will be absorbed by the liquid absorption unit 2, thus reducing the risk of leakage at the air inlet 30.

[0036] Please see Figure 2 and Figure 5In some embodiments, the number of air intake columns 3 is at least two, and the at least two air intake columns 3 are spaced apart. The liquid absorption unit 2 has a main liquid absorption region 21, which is located between two adjacent air intake columns 3, and the air outlet 40 and the main liquid absorption region 21 are directly opposite each other. Specifically, the vertical projections of the air outlet 40 and the main liquid absorption region 21 at least partially overlap. Thus, when condensate generated in the atomization channel 10 or liquid such as atomization matrix seeping from the atomization core 12 drips from the air outlet 40, the liquid will drip vertically to the position of the main liquid absorption region 21 and be absorbed by the liquid absorption unit 2.

[0037] Please see Figures 2 to 5 In some embodiments, the liquid suction unit 2 includes a first liquid suction member 22 and a second liquid suction member 23. The first liquid suction member 22 is disposed at the bottom of the accommodating cavity and surrounds the outer peripheral surface 32 of the air intake column 3. Specifically, the first liquid suction member 22 surrounds the outer periphery of all air intake columns 3, that is, for any air intake column 3, the first liquid suction member 22 surrounds its outer periphery. The main liquid suction area 21 is located on the first liquid suction member 22. When liquid drips from the air outlet 40, the liquid drips vertically to the position of the main liquid suction area 21 and is absorbed by the first liquid suction member 22. The first liquid suction member 22 serves as the main liquid suction component and liquid storage component. The second liquid suction member 23 is disposed above the first liquid suction member 22 and does not contact the air intake column 3. The second liquid suction member 23 constructs the air guiding space 20. The first liquid suction member 22 and the second liquid suction member 23 are two independent components, which are stacked one above the other and fit together. When the first liquid-absorbing element 22 is saturated, the excess liquid can be absorbed by the second liquid-absorbing element 23. That is, the second liquid-absorbing element 23 can provide both the air-guiding space 20 and supplement the first liquid-absorbing element 22, providing more liquid storage space.

[0038] Please see Figures 2 to 5 In some embodiments, the second liquid-absorbing member 23 includes at least two first liquid-absorbing portions 231 and at least one second liquid-absorbing portion 232. That is, the number of first liquid-absorbing portions 231 can be two or more; the number of second liquid-absorbing portions 232 can be one or more. At least two first liquid-absorbing portions 231 are spaced apart. Each second liquid-absorbing portion 232 has at least one air guide hole 24, which is connected to the atomization channel 10. The air guide hole 24 and the interval between the at least two first liquid-absorbing portions 231 together form an air guide space 20. Specifically, the first liquid-absorbing portions 231 and the second liquid-absorbing portions 232 are independent components, and each first liquid-absorbing portion 231 and the second liquid-absorbing portion 232 are stacked vertically and attached to each other. When the first liquid-absorbing member 22 is saturated with liquid, excess liquid can be absorbed by the first liquid-absorbing portions 231; when the first liquid-absorbing portion 231 is saturated with liquid, excess liquid can be absorbed by the second liquid-absorbing portion 232.

[0039] Please see Figures 2 to 5In some embodiments, the first liquid-absorbing member 22, the first liquid-absorbing section 231, and the second liquid-absorbing section 232 are stacked sequentially from bottom to top to form a three-layer liquid-absorbing structure. The first liquid-absorbing member 22 is located at the bottom layer and serves as the main liquid-absorbing component and liquid-storing component. When the liquid is saturated, it permeates from bottom to top into the second liquid-absorbing section 232 and the second liquid-absorbing section 232.

[0040] In some embodiments, the first liquid-absorbing element 22, the first liquid-absorbing portion 231, and the second liquid-absorbing portion 232 may each be made of a fiber material. The fiber material includes natural cotton, bamboo fiber, glass fiber, polyamide (PA, commonly known as nylon), polyethylene terephthalate (PET, commonly known as polyester), cellulose acetate (CA), and other materials.

[0041] Please see Figure 2 and Figure 5 In some embodiments, the cross-sectional dimension of the vent 24 is larger than that of the vent 40. Specifically, the cross-sectional area of ​​the vent 24 is larger than that of the vent 40. Due to the size difference, liquid dripping from the vent 40 can avoid the second liquid absorption section 232, preventing the second liquid absorption section 232 from becoming saturated prematurely and increasing the risk of liquid flowing back to the vent 40.

[0042] Please see Figure 2 In some embodiments, the first suction member 22 has a second top surface 25, which faces away from the bottom surface 43 of the accommodating cavity. The second top surface 25 is lower than the first top surface 31. That is, with the bottom surface 43 of the accommodating cavity as a reference, the vertical distance between the second top surface 25 and the bottom surface 43 is less than the vertical distance between the first top surface 31 and the bottom surface 43. Therefore, a height difference exists between the first suction member 22 and the air inlet 30, preventing liquid seeping from the first suction member 22 from flowing towards the air inlet 30, thereby reducing the risk of leakage at the air inlet 30. Thus, even if a small amount of liquid seeps from the first suction member 22 under conditions such as pressure changes, the liquid will be difficult to reach the air inlet 30 on the first top surface 31 due to the height difference, and the liquid seeping from the first suction member 22 can be absorbed by the second suction member 23.

[0043] Please see Figures 4 to 6In some embodiments, the atomizer further includes at least two conductive electrode posts 5. At least two limiting posts 44 are also formed on the base unit 4, which limit the electrode posts 5. Specifically, limiting holes 440 are formed on the limiting posts 44, the first end of the electrode post 5 is embedded in the limiting hole 440, and the second end of the electrode post 5 is electrically connected to the heating element 122 of the atomizing core 12. The first liquid-absorbing member 22 has at least one first clearance hole 221 and at least two second clearance holes 222. The air intake column 3 passes through the first clearance hole 221 for clearance, and the second clearance holes 222 are used to clear the limiting posts 44. The main liquid-absorbing area 21 is located between the two first clearance holes 221.

[0044] Please see Figures 2 to 5 In some embodiments, the atomizer further includes a housing 13, which has a first end and a second end. The first end has a mouthpiece 14, which communicates with the atomization channel 10, allowing the user to inhale through the mouthpiece 14. A base unit 4 is connected to the second end of the housing 13. The base unit 4 includes a base 41 and a sealing seat 42, which are connected together and together enclose a receiving cavity. The sealing seat 42 is fitted onto the outer periphery of the base 41. The outer periphery of the sealing seat 42 has a sealing ring, which seals against the inner wall of the housing 13. An air outlet 40 is formed on the sealing seat 42. A groove 420 is provided on the side of the sealing seat 42 facing away from the base 41, and this groove 420 communicates with the air outlet 40. The atomizer also includes an atomizing tube 15, the cavity of which forms an atomizing channel 10. One end of the atomizing tube 15 is embedded in a groove 420 for fixation, and the other end of the atomizing tube 15 is connected to the outer shell 13. The outer peripheral surface of the atomizing tube 15, the surface of the sealing seat 42 facing away from the base 41, and the outer shell 13 together define the liquid storage chamber 11. The air intake column 3 and the limiting column 44 are both formed on the base 41. The air intake column 3 and the base 41 can be integrally formed or they can be independent structures; similarly, the limiting column 44 and the base 41 can be integrally formed or they can be independent structures. The limiting hole 440 penetrates the surface of the base 41 facing away from the sealing seat 42 (i.e., the bottom surface of the base 41). The first end of the electrode post 5 is provided with a conductive part 51. The cross-sectional dimension of the conductive part 51 is larger than the cross-sectional dimension of the limiting hole 440, and the conductive part 51 is located on the side of the base 41 facing away from the sealing seat 42. When the atomizer and the power supply unit are connected together, the conductive part 51 and the battery cell of the power supply unit form an electrical connection. Thus, the battery cell of the power supply unit, the conductive part 51, the electrode post 5 and the heating element 122 of the atomizing core 12 are sequentially connected to form an electrical connection, thereby enabling the atomizing core 12 to enter the energized state to heat the atomizing matrix.

[0045] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
