The condensate will accumulate at the bottom of the electronic atomizer, causing the user to experience oil flying and gurgling sounds (condensation cracking) when using the electronic atomizer, thereby affecting the user's experience.

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The terms "first", "second", "third", "fourth" and so on (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The directional terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of this utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are intended only for clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in this utility model.

[0028] like Figures 1 to 6 As shown, the electronic atomizer provided by the embodiment of the present invention includes a housing 1, an atomizing core 2 and a liquid storage chamber 31, both of which are disposed in the housing 1. The liquid storage chamber 31 is used to store atomized liquid (such as e-liquid), and the atomizing core 2 is used to heat and atomize the atomized liquid to generate smoke.

[0029] The atomizer core 2 includes a porous base 21 and a heating element 22. The porous base 21 is provided with an atomization hole 211, which extends transversely through the porous base 21. The heating element 22 is disposed on the inner wall of the atomization hole 211. Atomized liquid stored in the liquid storage chamber 31 is transferred to the porous base 21. When powered on, the heating element 22 generates heat, thereby heating and atomizing the atomized liquid on the porous base 21.

[0030] The housing 1 is also provided with a base 4, which is located below the atomizer core 2. The base 4 is used to receive condensed liquid (i.e., after the residual vapor in the housing 1 forms condensed liquid, the condensed liquid will accumulate on the base 4). A liquid guide 23 is provided on the outer wall of the porous substrate 21. The liquid guide 23 is in contact with the outer wall of the porous substrate 21 and is disposed at least between the bottom of the porous substrate 21 and the base 4. The liquid guide 23 can conduct the condensed liquid on the base 4 to the porous substrate 21.

[0031] The atomizing holes 211 extend transversely through the porous substrate 21. Specifically, the axial direction of the atomizing holes 211 may be parallel to the horizontal direction, i.e., the atomizing holes 211 extend horizontally. Alternatively, the axial direction of the atomizing holes 211 may form a certain angle (generally small) with the horizontal direction, for example, the angle between the axial direction and the horizontal direction may be less than 30°, i.e., the atomizing holes 211 extend transversely and obliquely. Preferably, the atomizing holes 211 extend horizontally.

[0032] The electronic atomizer provided by the embodiment of the present invention is provided with a base 4, which is capable of receiving condensed liquid generated after the smoke condenses, and a liquid guide 23 is provided between the porous matrix 21 and the base 4. The liquid guide 23 can conduct the condensed liquid on the base 4 to the porous matrix 21 for re-atomization, thereby improving the utilization rate of the atomized liquid and reducing or avoiding the accumulation of condensed liquid at the bottom of the shell 1, thereby avoiding the occurrence of flying oil or gurgling sounds during use. The electronic atomizer does not need to be additionally provided with a capillary groove structure and oil-absorbing cotton at the bottom of the shell 1 for absorbing condensed liquid (because the oil-absorbing cotton has a limited oil absorption capacity and the condensed liquid absorbed by the oil-absorbing cotton cannot be consumed, it needs to be replaced after a period of use), thereby saving costs.

[0033] At the same time, since a horizontal atomizing core 2 is adopted, that is, a transversely penetrating atomizing hole 211 is provided on the porous substrate 21, and the heating element 22 is arranged on the inner wall of the atomizing hole 211, the atomized liquid on the porous substrate 21 is atomized in the atomizing hole 211, which can avoid the heating element 22 contacting the liquid guide part 23 and causing dry burning damage to the liquid guide part 23, and the liquid guide part 23 blocking the air path and affecting the atomization efficiency.

[0034] Specifically, if a traditional block-shaped porous matrix is ​​used, since the heating element 22 is generally arranged on the lower surface of the block-shaped porous matrix, if a liquid guide 23 is set between the bottom of the block-shaped porous matrix and the base 4, the liquid guide 23 will contact the heating element 22. Since the temperature of the heating element 22 is relatively high during operation and the amount of condensate on the liquid guide 23 is relatively small, the liquid guide 23 will be damaged by dry burning due to insufficient liquid supply.

[0035] If a traditional vertically arranged hollow cylindrical porous matrix is ​​used, since the air inlet end of the vertically arranged hollow cylindrical porous matrix is ​​located at its lower end, if a liquid guide 23 is set between the bottom of the hollow cylindrical porous matrix and the base 4, the liquid guide 23 will block the air inlet end of the hollow cylindrical porous matrix, thereby affecting the atomization efficiency and even making it impossible to perform normal atomization work (for electronic atomizers using block-shaped porous matrices and vertically arranged hollow cylindrical porous matrices, please refer to patents such as CN116268608A).

[0036] like Figure 3 As shown, as an embodiment, the porous matrix 21 is a columnar structure, and the porous matrix 21 can be made of porous ceramics, porous glass, etc. The atomization hole 211 is set in the middle of the porous matrix 21. The atomization hole 211 is a circular hole. The heating element 22 is a cylindrical structure and is embedded in the inner wall of the atomization hole 211. The heating element 22 can specifically be a heating mesh, a heating wire, etc. Of course, in other embodiments, the atomization hole 211 can also be of other shapes.

[0037] As an embodiment, the liquid guide member 23 is liquid guide cotton (oil guide cotton), which can absorb condensed liquid on the base 4 and conduct it to the porous matrix 21. Of course, in other embodiments, the liquid guide member 23 can also be made of other materials.

[0038] like Figure 3 and Figure 5 As shown, as an embodiment, the liquid guiding member 23 is an annular structure, and the liquid guiding member 23 is arranged outside the porous matrix 21. The atomized liquid stored in the liquid storage chamber 31 can be conducted to the porous matrix 21 through the liquid guiding member 23, thereby enabling the condensed liquid / atomized liquid on the liquid guiding member 23 to be evenly conducted to various positions on the porous matrix 21, and facilitating the assembly of the liquid guiding member 23 and the porous matrix 21.

[0039] As an embodiment, the base 4 is made of silicone material.

[0040] like Figure 2 and Figure 5 As shown, as an embodiment, a liquid storage 3 is provided in the housing 1. The liquid storage 3 is located above the atomizing core 2. The liquid storage 3 and the housing 1 are an integral structure (of course, in other embodiments, the liquid storage 3 and the housing 1 can also be separate structures). A liquid storage cavity 31 is provided in the liquid storage 3. A liquid outlet 32 ​​is provided at the bottom of the liquid storage 3 and is connected to the liquid storage cavity 31. The liquid outlet 32 ​​is provided corresponding to the porous matrix 21 and is located above the porous matrix 21. The atomized liquid stored in the liquid storage cavity 31 can be transferred to the porous matrix 21 through the liquid outlet 32.

[0041] Specifically, in this embodiment, the liquid guide 23 abuts against the bottom of the liquid storage 3 and blocks the liquid outlet 32, thereby allowing the atomized liquid stored in the liquid storage chamber 31 to pass through the liquid outlet 32 ​​and onto the porous substrate 21 via the liquid guide 23. Furthermore, the upper surface of the porous substrate 21 is a planar structure, and the top of the liquid guide 23 is a flat structure, thereby enabling the liquid guide 23 to better block and seal the liquid outlet 32.

[0042] like Figure 5 As shown, as an embodiment, the base 4 is fixedly arranged at the bottom of the housing 1 , and the base 4 abuts against the liquid guide 23 . The base 4 can support and fix the atomizer core 2 so that the atomizer core 2 is fixed in the housing 1 .

[0043] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, as an embodiment, a smoke outlet 11 is provided at the top of the housing 1, and an air inlet 12 is provided on the side wall of the housing 1. The height of the air inlet 12 is greater than the height of the base 4 (i.e., the air inlet 12 is located above the base 4). An air inlet channel 13 and a smoke outlet channel 14 are provided in the housing 1. The air inlet channel 13 and the smoke outlet channel 14 are respectively located on opposite sides of the porous base 21. The air inlet 12 is connected to one end of the atomization hole 211 through the air inlet channel 13, and the smoke outlet 11 is connected to the other end of the atomization hole 211 through the smoke outlet channel 14.

[0044] Specifically, during inhalation, outside air enters the atomizing hole 211 through the air inlet 12 and the air inlet channel 13, mixes with the smoke generated by the heated atomization in the atomizing hole 211, and is then discharged through the smoke outlet channel 14 and the smoke outlet 11 for the user to inhale. Because the air inlet 12 is provided on the side wall of the housing 1 and is higher than the height of the base 4, condensation accumulated on the base 4 is prevented from being discharged outside the housing 1 through the air inlet 12, thereby preventing it from affecting the user's experience.

[0045] like Figure 5 As shown, as an embodiment, the height of the air inlet 12 is greater than the height of the atomizing hole 211, that is, the air inlet 12 is located above the atomizing hole 211. This arrangement, on the one hand, can further ensure that the condensed liquid accumulated on the base 4 will not be discharged to the outside of the shell 1 through the air inlet 12 (the liquid level of the condensed liquid will not exceed the atomizing hole 211), and on the other hand, it can make the air path between the air inlet 12 and the atomizing hole 211 (that is, the air inlet channel 13) relatively tortuous, so as to prevent the smoke in the atomizing hole 211 from being discharged to the outside of the shell 1 through the air inlet 12 in the opposite direction after the user stops inhaling (if the height of the air inlet 12 and the atomizing hole 211 is the same or similar, after stopping inhalation, the smoke in the atomizing hole 211 will be more easily discharged through the air inlet 12).

[0046] like Figure 5 and Figure 6 As shown, as an embodiment, the air inlet channel 13 includes a first sub-air channel 131 and a second sub-air channel 132. The first sub-air channel 131 is arranged between the side wall of the liquid storage 3 and the inner wall of the shell 1, and the second sub-air channel 132 is located below the first sub-air channel 131. The second sub-air channel 132 is located on the air inlet side of the atomization hole 211. One end of the first sub-air channel 131 is connected to the air inlet 12, and the other end of the first sub-air channel 131 is connected to the atomization hole 211 through the second sub-air channel 132. That is, in this embodiment, the air inlet channel 13 is a side-type air inlet structure; when inhaling, the outside air enters the atomization hole 211 through the air inlet 12, the first sub-air channel 131, and the second sub-air channel 132 in sequence.

[0047] The smoke outlet channel 14 includes a first flue 141 and a second flue 142. The first flue 141 is disposed between the side wall of the liquid storage 3 and the inner wall of the housing 1. The second flue 142 is located below the first flue 141 and on the smoke outlet side of the atomization hole 211. One end of the first flue 141 is connected to the smoke outlet 11, and the other end of the first flue 141 is connected to the atomization hole 211 through the second flue 142. That is, in this embodiment, the smoke outlet channel 14 is a side-type smoke exhaust structure. After the outside air mixes with the smoke in the atomization hole 211, it is discharged through the second flue 142, the first flue 141, and the smoke outlet 11 in sequence.

[0048] like Figure 4 and Figure 5 As shown, as an embodiment, the upper surface of the base 4 is provided with a receiving groove 41 for receiving condensed liquid, and the bottom of the liquid guide 23 is located in the receiving groove 41. That is, after the smoke remaining in the housing 1 forms condensed liquid, the condensed liquid will accumulate in the receiving groove 41 on the base 4. Because the bottom of the liquid guide 23 is located in the receiving groove 41, the liquid guide 23 can absorb the condensed liquid in the receiving groove 41 and then conduct it to the porous base 21.

[0049] like Figure 5 As shown, as an embodiment, the bottom of the liquid-guiding member 23 is spaced apart from the inner wall of the receiving groove 41, that is, the bottom of the liquid-guiding member 23 does not contact the inner wall of the receiving groove 41 (it should be noted that, although the liquid-guiding member 23 does not contact the inner wall of the receiving groove 41 in this embodiment, the liquid-guiding member 23 abuts against other parts of the base 4, so that the base 4 can support and fix the atomizer core 2). Of course, in other embodiments, the bottom of the liquid-guiding member 23 can also contact the inner wall of the receiving groove 41.

[0050] like Figure 4 and Figure 5 As shown, as an embodiment, the accommodating groove 41 includes a first groove 411, a second groove 412 and a third groove 413 that are interconnected. The first groove 411 is located directly below the liquid guide member 23, and the bottom of the liquid guide member 23 is located in the first groove 411; the second groove 412 and the third groove 413 are respectively located on opposite sides of the first groove 411, and the second groove 412 is arranged corresponding to the air inlet side of the atomization hole 211, the second groove 412 is located below the second sub-air duct 132, the third groove 413 is arranged corresponding to the smoke outlet side of the atomization hole 211, and the third groove 413 is located below the second flue 142.

[0051] Specifically, by setting the second groove 412 and the third groove 413, the second groove 412 can collect the condensate generated in the second sub-air duct 132, and the third groove 413 can collect the condensate generated in the second flue 142, and the second groove 412 and the third groove 413 are both connected to the first groove 411, so that the liquid guide 23 can absorb the condensate in the first groove 411, the second groove 412 and the third groove 413 at the same time.

[0052] like Figure 4 and Figure 5 As shown, as an embodiment, the depth of the first groove 411 is less than the depth of the second groove 412 and the depth of the third groove 413, that is, the inner bottom surface of the first groove 411 is higher than the inner bottom surface of the second groove 412 and the inner bottom surface of the third groove 413, thereby raising the liquid level of the condensate in the first groove 411, making it easier for the liquid guide 23 to absorb the condensate in the first groove 411 and improving the liquid guide efficiency.

[0053] like Figure 5 As shown, as an embodiment, the opposite ends of the liquid guiding member 23 extend into the second groove 412 and the third groove 413 respectively, so that the liquid guiding member 23 can directly absorb the condensed liquid in the second groove 412 and the third groove 413, thereby improving the liquid guiding efficiency.

[0054] like Figures 3 to 5 As shown, as an embodiment, the bottom of the porous matrix 21 and the bottom of the liquid guide 23 are both arc-shaped structures, and the inner bottom surface of the first groove 411 is an arc-shaped structure that imitates the bottom of the liquid guide 23.

[0055] like Figure 1 、 Figure 2 and Figure 5 As shown, as an embodiment, the housing 1 includes a main housing 10A and a mouthpiece 10B. The mouthpiece 10B is detachably connected to the main housing 10A (specifically, via a snap connection). The atomizer core 2 and liquid storage 3 are both disposed within the main housing 10A. The air inlet 12 is disposed on the side wall of the main housing 10A, and the smoke outlet 11 is disposed on the mouthpiece 10B. The top of the main housing 10A is provided with a top opening (not numbered in the figure) that communicates with the liquid storage chamber 31. A sealing plug 5 is disposed at the top opening, which is provided with a liquid injection port 51. The mouthpiece 10B is provided with a sealing portion 15 that plugs into and engages with the liquid injection port 51. When the mouthpiece 10B is removed from the main housing 10A, the sealing portion 15 is removed from the liquid injection port 51, and atomized liquid can be injected into the liquid storage chamber 31 through the liquid injection port 51. When the mouthpiece 10B is reassembled with the main housing 10A, the sealing portion 15 is reinserted into the liquid injection port 51 to seal the liquid injection port 51. The sealing plug 5 can be made of silicone.

[0056] like Figure 1 、 Figure 2 and Figure 5 As shown, as an embodiment, the bottom of the main housing 10A is provided with a bottom opening (not numbered in the figure), and the base 4 is disposed at the bottom opening and seals the bottom opening. The housing 1 also includes a base 10C, which is fixedly connected to the bottom of the main housing 10A (specifically, fixed by a snap connection). The upper half of the base 4 is located within the main housing 10A and has an interference fit with the inner wall of the main housing 10A. The lower half of the base 4 is sandwiched between the base 10C and the bottom of the main housing 10A, thereby securing the base 4.

[0057] like Figure 1 、 Figure 2 and Figure 5 As shown, as an embodiment, the electronic atomizer further includes a mouthpiece plug 6 , which is detachably connected to the cigarette holder 10B. The mouthpiece plug 6 is disposed at the cigarette outlet 11 and is used to seal the cigarette outlet 11 .

[0058] like Figures 2 to 5 As shown, as an embodiment, the atomizer core 2 further includes two electrode leads 221, which are respectively connected to the two ends of the heating element 22; two conductive electrodes 44 are provided in the base 4, and the two electrode leads 221 are respectively connected to the two conductive electrodes 44. The two conductive electrodes 44 are respectively used to connect to the positive and negative poles of the power supply component in the battery rod (not shown), thereby supplying power to the atomizer core 2.

[0059] Specifically, in this embodiment, a wire hole 45 is provided on the base 4 , and the wire hole 45 is a blind hole. The electrode lead 221 is connected to the conductive electrode 44 through the wire hole 45 .

[0060] like Figure 2 、 Figure 4 and Figure 5 As shown, as an embodiment, the base 4 is provided with a mounting hole 42, which is in communication with the second flue 142. An air pressure sensing element (not shown, i.e., a microphone) is disposed in the mounting hole 42. The air pressure sensing element is used to electrically connect to the power supply assembly in the battery rod; the air pressure sensing element acts as a switch element to control the on / off of the circuit between the power supply assembly and the atomizer core 2, thereby controlling the opening and closing of the atomizer core 2.

[0061] Specifically, during inhalation, the gas in the mounting hole 42 will be sucked into the second flue 142, causing the air pressure in the mounting hole 42 to decrease. The air pressure sensing element opens after sensing the air pressure change, thereby connecting the power supply assembly to the atomizer core 2 and supplying power to the atomizer core 2.

[0062] like Figure 2 、 Figure 4 and Figure 5As shown in the figure, as an embodiment, since the base 4 is made of soft silicone material, in order to prevent the mounting hole 42 from collapsing and causing the air pressure sensing element to be unable to open normally, a hollow tube 43 is provided in the mounting hole 42, and the air pressure sensing element is disposed in the hollow tube 43. The hollow tube 43 can be made of a hard material such as plastic or metal.

[0063] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
