[0017] In some embodiments, the atomizer further includes an end cap that is connected to the base and covers the receiving groove and the liquid absorption structure.

[0044] This application provides an electronic atomizing device 300, see reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application. Figure 2 Is it like this? Figure 1 A cross-sectional view of the atomizer in the electronic atomizing device shown.

[0045] The electronic atomizing device 300 may include a detachably connected atomizer 100 and a main unit 200, that is, the atomizer 100 is replaceable, the main unit 200 is used to power the atomizer 100, and the atomizer 100 is used to store the aerosol matrix and atomize the aerosol matrix to generate an aerosol.

[0046] The electronic atomizing device 300 can also be a disposable device, meaning that the aerosol matrix carried by the electronic atomizing device 300 can be discarded after use; it can also include a non-removable atomizer 100 and a main unit 200.

[0047] In this embodiment, the atomizer 100 and the main unit 200 are detachably connected. The main unit 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect the atomizer 100 to identify information of the atomizer 100 and control the power supply mode to the atomizer 100 according to the identification information.

[0048] like Figure 2As shown, the atomizer 100 includes a liquid storage chamber 10, a top cover 20, an atomizing core 30, a base 40, and multiple electrodes 50. The top cover 20 is connected to the liquid storage chamber 10 and forms a liquid storage cavity 12. The atomizing core 30 is disposed on the top cover 20. The base 40 is connected to the liquid storage chamber 10 and / or the top cover 20, and forms an atomizing cavity 22 between the base 40 and the top cover 20. The multiple electrodes 50 are connected to the base 40 and electrically connected to the atomizing core 30. The electrodes 50 can be pressed onto the atomizing core 30, or the electrodes 50 can be welded onto the atomizing core 30, or the atomizing core 30 can be pressed onto the top cover 20 by the base 40. The electrodes 50 are used to connect to a battery in the main unit 200 to supply power to the atomizing core 30.

[0049] The base 40 can be screwed onto the liquid storage tank 10 or the top cover 20. The base 40 can also be directly embedded in the open end of the liquid storage tank 10, or embedded in the open end of the liquid storage tank 10 through a sealing ring, and / or the base 40 is also connected to the top cover 20. This application does not make specific limitations in this regard.

[0050] See also Figures 3 to 5 , Figure 3 Is it like this? Figure 2 The diagram shows the assembly structure of the atomizer, including the base, flexible components, and electrodes. Figure 4 Is it like this? Figure 3 A schematic cross-sectional view of the structure shown along the AA direction. Figure 5 Is it like this? Figure 3 The diagram shown is a bottom view of one embodiment of the structure.

[0051] The base 40 is provided with an air inlet 42 and a receiving groove 44. The air inlet 42 and the receiving groove 44 are located on the same end face of the base 40. Specifically, the air inlet 42 and the receiving groove 44 are located on the end face of the base 40 away from the atomizing core 30. The air inlet 42 is used to supply air to the atomizing chamber 22.

[0052] The atomizer 100 also includes an electronic component 60, which is housed in a receiving slot 44 and electrically connected to a plurality of electrodes 50. The electronic component 60 can be used for anti-counterfeiting and / or identification of the type of the atomizer 100.

[0053] The electronic component 60 can be an anti-counterfeiting chip or a structure where the anti-counterfeiting chip is set on the PCB. The electronic component 60 is used for anti-counterfeiting to prevent counterfeit atomizers 100 from being produced on the market. After the host 200 is electrically connected to the atomizer 100, if the anti-counterfeiting information on the electronic component 60 is incorrect or cannot be identified, the control element of the host 200 will stop supplying power to the atomizer core 30 to avoid harm to the user due to counterfeit products.

[0054] The electronic component 60 may also carry information data of the atomizer 100, so that after the control element of the host 200 obtains the information data, it can identify the type of the atomizer 100, and then the control element supplies power to the atomizer 100 based on the control method that matches the type of the atomizer 100.

[0055] The type of atomizer 100 can be the type of aerosol matrix stored within it. The atomizer 100 can store different types of aerosol matrices. Different types of aerosol matrices may require different optimal atomization temperatures. The aerosol matrix can only be atomized more fully when it is atomized at the corresponding optimal atomization temperature. Therefore, the control element identifies the type of aerosol matrix through the information on the electronic component 60, and can output power supply parameters that match the type of aerosol matrix to the atomizer 100. The power supply parameters can be the power supply voltage value and / or the power supply current value, so that the aerosol matrix can be atomized at the optimal atomization temperature.

[0056] Due to its electrical characteristics, electronic component 60 is easily damaged when it comes into contact with liquid, which can lead to functional failure. In particular, the aerosol matrix and its condensate generated in the atomization chamber 22 can easily cause corrosion of electronic component 60. Therefore, it is necessary to prevent the aerosol matrix and its condensate from flowing back and corroding electronic component 60.

[0057] like Figure 5 As shown, in this embodiment, an isolation structure 41 is formed between the air inlet 42 and the accommodating groove 44, and a liquid absorption structure 43 is also provided on the base 40. The liquid absorption structure 43 is used to absorb the fluid leaking from the air inlet 42. The fluid may be aerosol and its condensate flowing back from the atomizing chamber 22 to the air inlet 42.

[0058] The isolation structure 41 is used to laterally block the air inlet 42 and the receiving tank 44, preventing the fluid leaking from the air inlet 42 from flowing directly into the receiving tank 44. Furthermore, by setting the liquid absorption structure 43 to absorb the fluid leaking from the air inlet 42, the aerosol and its condensate flowing back from the air inlet 42 can be effectively prevented from corroding the electronic components 60 in the receiving tank 44, thus effectively reducing the risk of damage to the electronic components 60 due to corrosion.

[0059] The isolation structure 41 may be the part of the base 40 itself located between the air inlet 42 and the receiving groove 44, and may also include the electrode 50.

[0060] There can be multiple electrodes 50, such as two or three. For example, if there are three electrodes 50, the main unit 200 is electrically connected to two of the electrodes 50. The three electrodes 50 can be combined into three sets of electrode pairs. Each set of electrode pairs can correspond to a different power supply voltage. That is, by changing the main unit 200, different electrode pairs can be powered on, thereby changing the power supply voltage to the atomizer 100.

[0061] The base 40 is provided with at least one air inlet 42. The number of air inlets 42 can be one, two or three, etc., and this application does not limit it.

[0062] Optionally, the isolation structure 41 is the part of the base 40 itself located between the air inlet 42 and the receiving groove 44, and the electrode 50 is located in the area of ​​the base 40 that is not between the air inlet 42 and the receiving groove 44.

[0063] In this embodiment, as Figure 5 As shown, the end face of the base 40 is elliptical. Considering that electronic components 60, multiple electrodes 50, air inlets 42, and liquid absorption structures 43 are to be installed on the base 40, the electronic components 60, multiple electrodes 50, air inlets 42, and liquid absorption structures 43 are arranged along the long axis of this ellipse to make full use of the space along the long axis to arrange the various structural features. Furthermore, the electrodes 50 are placed between the air inlets 42 and the receiving groove 44 to form part of the isolation structure 41, making the distribution of the structural features more compact. This makes it easier to meet the aperture size requirements of the air inlets 42, thereby ensuring sufficient and smooth air supply to the atomizing chamber 22. It also allows the liquid absorption structure 43 to occupy a larger area, thereby obtaining stronger liquid absorption and storage capacity. As a result, all features on the base 40 can achieve complete functions, avoiding functional impairment due to size limitations.

[0064] In this embodiment, at least a portion of the plurality of electrodes 50 are disposed between the air inlet 42 and the receiving groove 44, forming at least a portion of the isolation structure 41.

[0065] For example, there are two electrodes 50 and one air inlet 42. One electrode 50 is disposed in the area between the air inlet 42 and the receiving groove 44 to form at least a part of the isolation structure 41, and the other air inlet 42 may be disposed on the side of the receiving groove 44 away from the air inlet.

[0066] Alternatively, there may be two electrodes 50 and two air inlets 42, with the two air inlets 42 located on both sides of the receiving groove 44, and the two electrodes 50 also located on both sides of the receiving groove 44 and respectively located in the area between the air inlets 42 and the receiving groove 44.

[0067] See also Figure 4 , Figure 5 and Figure 7 ,in Figure 7 Is it like this? Figure 5 or Figure 6 A schematic diagram of the structure of the central base from below.

[0068] In this embodiment, the base 40 is provided with an electrode hole 45, and the electrode 50 is detachably connected to the electrode hole 45 to facilitate the replacement and assembly of the electrode 50. The electrode hole 45 includes a first hole segment 451 and a second hole segment 452 arranged in a stepped manner. The cross-sectional area of ​​the first hole segment 451 along its extension direction is greater than the cross-sectional area of ​​the second hole segment 452 along its extension direction. The first hole segment 451 is at least laterally connected to the receiving groove 44, and the second hole segment 452 is spaced apart from the air inlet 42 and the receiving groove 44.

[0069] Electrode 50 is a pin, which includes a conductive disk 51 and a conductive needle 52 arranged in a stepped manner. The cross-sectional area of ​​the conductive disk 51 along the extension direction is larger than the cross-sectional area of ​​the conductive needle 52 along the same direction. The conductive disk 51 is assembled with the first hole segment 451, and the conductive needle 52 is assembled with the second hole segment 452. That is, the relatively larger area of ​​the conductive disk 51 is conducive to realizing the electrical connection relationship with the corresponding electrode on the host 200.

[0070] like Figure 7 As shown, the first hole segment 451 is at least laterally connected to the receiving groove 44. Lateral refers to the direction perpendicular to the extension direction of the first hole segment 451, specifically the major axis direction of this type of ellipse in this embodiment. That is, the first hole segment 451 and the receiving groove 44 are unobstructed in the lateral direction. Part of the outer wall surface of the conductive disk 51 also constitutes part of the groove wall surface of the receiving groove 44, thereby making the electrode 50 and the receiving groove 44 more compactly distributed and requiring a smaller distribution area, which is more conducive to the distribution of various structural features on the base 40 and avoids damage to functions such as the air inlet 42 and the liquid absorption structure 43 due to the size limitation of the base 40.

[0071] In one embodiment, such as Figure 5 and Figure 7 As shown, the baffle 411 formed between the first hole section 451 and the air inlet 42, the isolation structure 41 includes the baffle 411 and the electrode 50. That is, one way to implement the isolation structure 41 is the baffle 411 and the electrode 50 between the air inlet 42 and the receiving groove 44, thereby forming a primary barrier to isolate the fluid that flows back from the air inlet 42, preventing the backflowing fluid from flowing directly to the receiving groove 44, and thus effectively reducing the risk of fluid corrosion to the internal electronic components 60.

[0072] See also Figure 5 and Figure 6 ,in Figure 6 Is it like this? Figure 3 The diagram shows a bottom view of the structure of the second embodiment.

[0073] Furthermore, the atomizer 100 also includes a first seal 71, which is sealed between the electrode 50 and the orifice wall of the first orifice 451, so as to make it more secure and tighter connected to the base 40.

[0074] See also Figure 8 and Figure 9 , Figure 8 Is it like this? Figure 3 The diagram shows a bottom view of the structure in three embodiments. Figure 9 Is it like this? Figure 8 A schematic diagram of the structure of the central base from below.

[0075] In another embodiment, the first hole segment 451 is further laterally connected to the air inlet 42, that is, the two sides of the first hole segment 451 are laterally connected to the receiving groove 44 and the air inlet 42 respectively. The first hole segment 451 and the air inlet 42 are unobstructed in the lateral direction, that is, there is no baffle 411, which makes the distribution of the air inlet 42, the electrode 50 and the receiving groove 44 more compact, and the required distribution area is further reduced.

[0076] The atomizer 100 also includes a first seal 71, which is sealed between the electrode 50 and the orifice wall of the first orifice 451 to eliminate the gap between the conductive disk 51 and the orifice wall of the first orifice 451. Another implementation of the isolation structure 41 includes the first seal 71 and the electrode 50. Thus, the isolation structure 41 can form a primary barrier to the fluid that flows back from the air inlet 42, preventing the backflowing fluid from entering the receiving groove 44 through the gap, and effectively reducing the risk of fluid corrosion to the internal electronic components 60.

[0077] In some embodiments, the three implementations of the isolation structure 41 described above may coexist, or only one or two of them may coexist. This application does not limit this.

[0078] See Figure 10 , Figure 10 Is it like this? Figure 3 The diagram shows a bottom view of the four embodiments of the structure.

[0079] Based on the above embodiments, the atomizer 100 further includes a second sealing member 72. The second sealing member 72 is provided with a clearance hole 720 corresponding to the electrode 50. The second sealing member 72 is also sleeved on the electrode 50 and covers the receiving groove 44 to cover the electronic component 60. The second sealing member 72 is interference-fitted with the electrode 50, thereby better isolating the receiving groove 44, so that the electronic component 60 in the receiving groove 44 is protected from contact with the backflowing fluid and is protected from fluid corrosion.

[0080] like Figure 2As shown, the atomizer 100 also includes an end cap 73, which is connected to the base 40 and seals the receiving groove 44 and the liquid suction structure 43 to further increase the isolation of the receiving groove 44, reduce the risk of corrosion of the electronic components 60 inside it due to contact with the fluid flowing back from the air inlet 42, and can also shield the liquid suction structure 43 to reduce the risk of leakage of the liquid suction structure 43.

[0081] End cap 73 can be directly connected to base 40, or end cap 73 can be indirectly connected to base 40 by connecting to the outer wall of liquid storage tank 10. End cap 73 can directly cover receiving groove 44, or end cap 73 can cover receiving groove 44 by pressing the second sealing member 72.

[0082] Electrode 50 is exposed from end cap 73 for easy electrical connection to main unit 200. End cap 73 is provided with clearance hole, through which air inlet 42 and electrode 50 are exposed.

[0083] See Figures 5 to 10 The liquid absorption structure 43 can be a capillary groove to absorb the backflowing aerosol and its condensate using capillary force; the liquid absorption structure 43 can also be absorbent cotton. The liquid absorption structure 43 can be set on either side of the air inlet 42 or around the air inlet 42 so that the liquid absorption structure 43 can easily absorb the fluid leaking from the air inlet 42.

[0084] In this embodiment, the liquid absorption structure 43 is located on the side of the air inlet 42 away from the isolation structure 41, so that the fluid it adsorbs is far away from the isolation structure 41, thereby reducing the risk of electronic components 60 in the accommodating tank 44 coming into contact with the fluid.

[0085] Specifically, the air inlet 42 is located at the bottom of the settling tank on the base 40, and the liquid absorption structure 43 includes a capillary groove 431 that connects to the settling tank so as to connect to the air inlet 42 through the settling tank. Alternatively, the capillary groove 431 can be directly connected to the wall of the air inlet 42 to absorb any leaked fluid.

[0086] At least one air inlet 42 is provided between the liquid absorption structure 43 and the isolation structure 41. There are multiple capillary grooves 431 so that the leaked fluid can be fully and timely absorbed by the multiple capillary grooves 431, thereby reducing the risk of fluid flowing to the receiving tank 44. The multiple capillary grooves 431 all extend along the isolation structure 41 toward the air inlet 42, that is, the multiple capillary grooves 431 extend along the long axis. The extension length of the multiple capillary grooves 431 can be different, so that it makes full use of the area of ​​the air inlet 42 away from the isolation structure 41 to improve its liquid storage capacity.

[0087] Multiple air inlets 42 are provided between the liquid absorption structure 43 and the isolation structure 41. The multiple air inlets 42 are arranged side by side, and the arrangement direction of the multiple air inlets 42 is perpendicular to the spacing direction between the isolation structure 41 and the liquid absorption structure 43. That is, in this embodiment, the liquid absorption structure 43, the air inlets 42, the isolation structure 41, and the receiving groove 44 are distributed along the long axis direction, and the arrangement direction of the multiple air inlets 42 is the short axis direction of the end face of the base 40. By providing multiple air inlets 42, the aperture of a single air inlet 42 can be reduced. The multiple air inlets 42 between the liquid absorption structure 43 and the isolation structure 41 are arranged along the short axis direction, so as to utilize the space of the end face of the base 40 in the short axis direction to arrange the multiple air inlets 42, thereby saving the size distribution of the air inlets 42 in the long axis direction, thus leaving more space for the liquid absorption structure 43, the isolation structure 41, and the receiving groove 44 to be distributed.

[0088] In this embodiment, two isolation structures 41, multiple air inlets 42, and two liquid suction structures 43 are symmetrically distributed on both sides of the accommodating tank 44. That is, an isolation structure 41 is provided on the side of each air inlet 42 facing the accommodating tank 44, and a liquid suction structure 43 is provided on the side of each air inlet 42 away from the accommodating tank 44. Thus, the isolation structure 41 blocks the fluid leaking from the air inlet 42, and the liquid suction structure 43 absorbs the leaked fluid. The combination of these two means effectively reduces the adverse effects of the leaked fluid on the electronic components 60 in the accommodating tank 44, and can achieve good protection for the electronic components 60.

[0089] Optionally, the liquid absorption structure 43 may also include liquid-absorbing cotton. The base 40 is provided with a groove, and the air inlet 42 communicates with the groove. The liquid-absorbing cotton is filled in the groove, so that the liquid-absorbing cotton is located on one side of the air inlet 42 or is arranged around the air inlet 42. The liquid-absorbing cotton can also effectively absorb the leaked fluid.

[0091] The atomizer 100 also includes a flexible component 80, which is disposed on the side of the base 40 away from the receiving groove 44 and forms an air intake channel 46 between it and the base 40. An air intake hole 42 is connected to the air intake channel 46. An air outlet hole 82 is formed on the flexible component 80, which is connected to the air intake channel 46 and is disposed corresponding to the receiving groove 44. That is, the bottom wall of the receiving groove 44 also serves as the side wall of the air intake channel 46. When the aerosol and its condensate in the atomizing chamber 22 flow back, they enter through the air outlet hole 82. The bottom wall of the receiving groove 44 separates the air intake channel 46 and the receiving groove 44, thereby blocking the flow of aerosol and its condensate and preventing the flow of fluid from entering the receiving groove 44.

[0092] Air from outside the atomizer 100 enters the atomization chamber 22 through the air inlet 42, the air inlet channel 46, and the air outlet 82. The electronic component 60 and the air outlet 82 are both centrally located, with the air outlet 82 facing the atomizing core 30, so that the airflow entering the atomization chamber 22 blows towards the atomizing core 30, so as to fully carry away the aerosol.

[0093] Specifically, the flexible element 80 is sandwiched between the top cover 20 and the base 40, and an atomizing chamber 22 is formed between the flexible element 80 and the top cover 20. An air intake channel 46 is formed between the flexible element 80 and the base 40. The electrode 50 passes through the flexible element 80 and is electrically connected to the atomizing core 30. The top cover 20 and the base 40 clamp the flexible element 80 to form a sealed structure, and the outer periphery of the flexible element 80 is also pressed against the inner wall of the liquid storage tank 10 to form a sealed structure, which can effectively prevent the airflow in the atomizing chamber 22 from leaking out from these places.

[0094] Furthermore, the flexible element 80 is interference-fitted with the electrode 50, and the flexible element 80 is also elastically pressed against one end of the second hole section 452, thereby preventing the backflowing fluid from entering the second hole section 452.

[0095] In this embodiment, air inlets 42 are symmetrically provided on both sides of the receiving groove 44, and the air inlet channel 46 spans the receiving groove 44 and connects the air inlets 42 on both sides of the receiving groove 44, so as to increase the air supply of the air inlets 42 and reduce the risk of eddies generated in the air inlet channel 46, making the air supply faster and more sufficient.

[0096] The air outlet 82 is a racetrack-shaped hole, with the long side of the racetrack-shaped hole aligned with the long side of the atomizing core 30 in the atomizer 100 and positioned corresponding to the receiving groove 44. This centralizes the air outlet 82, allowing the airflow entering the atomizing chamber 22 through the racetrack-shaped hole to be evenly blown around the atomizing surface of the atomizing core 30. The aerosol generated on the atomizing surface is smoothly carried into the vertical air channels on both sides of the atomizing core 30 by the airflow, and finally converges at the inlet of the air channel tube of the liquid storage chamber 10, reducing the risk of eddy current generation and increasing the atomization volume.

[0097] Furthermore, the projection of the center of the racetrack-shaped hole along the direction of the flexible member 80 toward the atomizing core 30 is located at the center of the atomizing core 30, that is, the racetrack-shaped hole and the atomizing core 30 are centered. Utilizing the characteristics of the racetrack-shaped hole, the airflow entering the atomizing chamber through the racetrack-shaped hole and the airflow in the atomizing chamber will not generate collision vortices due to the airflow direction, reducing aerosol loss and effectively improving the output atomization volume.

[0098] The flexible component 80 has a liquid absorption groove 84 on the side facing the atomizing core 30 in the atomizer 100, and the liquid absorption groove 84 is located near the air outlet 82. In this embodiment, the air outlet 82 has elongated liquid absorption grooves 84 on both sides to facilitate the collection of liquids such as condensate and reduce the amount of fluid flowing back to the air inlet channel 46.

[0099] The flexible component 80 has a guide surface 86 on the side facing the base 40. The guide surface 86 is used to guide the gas entering from the air inlet 42 to the air outlet 82, so that the airflow flows more smoothly to the air outlet 82 and reduces the generation of vortices in the air inlet channel 46.

[0100] Unlike existing technologies, this application discloses an electronic atomizing device and its atomizer. By providing an isolation structure between the air inlet and the receiving groove on the base, the isolation structure laterally blocks the air inlet and the receiving groove, preventing fluid leaking from the air inlet from flowing directly into the receiving groove. Furthermore, by providing a liquid-absorbing structure on the base to absorb fluid leaking from the air inlet, the aerosol and its condensate flowing back from the air inlet can be effectively prevented from corroding the electronic components in the receiving groove, effectively reducing the risk of damage to the electronic components due to corrosion.

[0101] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
