[0037] In this application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions.

The airflow sensor 20 and the battery cell 30 are both installed on the bracket 10. The control board 40 is connected to the bracket 10 and shields the airflow sensor 20 from one side. The electrode is arranged on the bracket 10 and connected to the control board 40. The electrode is used to connect the atomizer 200 to the outside to supply power to the atomizer 200. The shell 50 encloses a receiving cavity 501.

The shell 50 is also provided with an opening. The atomizer 200 is arranged at the opening of the shell 50 to be electrically connected to the power supply assembly 100.

[0040] In one embodiment, magnetic elements are disposed on the power supply assembly 100 and the atomizer 200 so that the power supply assembly 100 and the atomizer 200 can be detachably connected through magnetic attraction.

[0041] In another embodiment, a fixing structure is provided on both the power assembly 100 and the atomizer 200. For example, a groove is provided on the power assembly 100 and a protrusion is provided on the atomizer 200; or a protrusion is provided on the power assembly 100 and a groove is provided on the atomizer 200. The power assembly 100 and the atomizer 200 are detachably connected through the fixing structure.

[0046] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] Combined with reference Figures 2 to 5 The bracket 10 includes a back plate 11 and a connecting seat 12 arranged at one end of the back plate 11. The end of the connecting seat 12 away from the back plate 11 is provided with a liquid storage tank 13 and an air intake column 14. The back plate 11 is provided with a mounting cavity 110. The mounting cavity 110 is used to install the airflow sensor 20. The air intake column 14 has an air hole 140. The air hole 140 connects the liquid storage tank 13 and the mounting cavity 110. After the airflow sensor 20 senses the airflow change in the liquid storage tank 13 through the air hole 140, the power supply assembly 100 supplies power to the atomizer 200.

[0048] A receiving groove 130 is provided on each side of the liquid storage tank 13. The receiving groove 130 is used to install the electrode. The receiving groove 130 can also be used to install the magnetic member. For example, the magnetic member is arranged in the receiving groove 130 and is arranged around the electrode. The magnetic member can be a permanent magnet or a ferromagnet, etc. The magnetic member is used to be magnetically connected to the atomizer 200, and the electrode is used to be electrically connected to the atomizer 200.

[0049] Optionally, the airflow sensing element 20 is accommodated in the installation cavity 110, and a liquid absorbing element may be provided in the installation cavity 110. The liquid absorbing element may be liquid absorbing cotton, liquid absorbing paper or desiccant, etc. The liquid absorbing element is used to absorb liquid leaking into the installation cavity 110 to avoid damage to the airflow sensing element 20 due to liquid leakage, thereby reducing the risk of failure of the airflow sensing element 20 and increasing the service life of the airflow sensing element 20. In this embodiment, the battery cell 30 and the control board 40 are also installed on the back plate 11; the housing 50 is provided with an air intake hole 51, and the outside air flows through the liquid storage tank 13 and flows to the atomizer 200 through the air intake hole 51, and then the air hole 140 can be used to detect whether the user draws the atomizer 200.

[0050] In other embodiments, the bracket 10 may also include only the connecting seat 12, and the airflow sensor 20, the battery cell 30 and the control board 40 may also be arranged on other structural parts; or the bracket 10 may also have other shapes, for example, the bracket 10 is generally prismatic or cylindrical, etc., and the present application does not impose specific restrictions on this.

[0051] In this embodiment, Figure 2 and Figure 3 As shown, a liquid reservoir 13 and an air inlet column 14 are provided at one end of the bracket 10, and the air inlet column 14 is provided with an air hole 140, and the air hole 140 is fluidically connected to the liquid reservoir 13, and the air inlet column 14 is provided with a drainage structure 15 around the air hole 140, and the drainage structure 15 is used to drain the liquid to the liquid reservoir 13. It should be noted that fluid communication means that the air flow can flow between the area of ​​the liquid reservoir 13 and the area of ​​the air hole 140.

[0052] like Figure 4 As shown, in this embodiment, the air hole 140 is arranged at one end of the air inlet column 14 away from the bottom wall of the liquid storage tank 13, and the drainage structure 15 is arranged around the air hole 140 to increase the height of the air hole 140 to prevent excessive accumulated liquid in the liquid storage tank 13 from flowing into the air hole 140.

[0053] Optional, see Figure 5 The air hole 140 can also be set on the side wall of the air inlet column 14, and the drainage structure 15 is set around the air hole 140, thereby preventing the condensate on the atomizer 200 from directly dripping into the air inlet hole 140.

[0054] In one embodiment, the air inlet hole on the atomizer 200 is arranged substantially opposite to the center of the liquid storage tank 13 , and the position of the air inlet column 14 is offset from the position of the air inlet hole of the atomizer 200 to prevent leaked liquid from falling into the air hole 140 .

[0055] Optionally, the air intake column 14 can be arranged in the liquid storage tank 13, that is, the air intake column 14 is connected to the bottom wall of the liquid storage tank 13, and the air intake column 14 is spaced apart from the side wall 132 of the liquid storage tank 13; or, the air intake column 14 can also be partially or completely embedded in the side wall 132 of the liquid storage tank 13, so that it can be at a greater distance from the air intake hole of the atomizer 200, which can significantly reduce the risk of liquid leakage into the air hole 140.

[0056] The air inlet on the atomizer 200 faces the liquid storage tank 13, which is mainly used to accumulate liquid leaking from the air inlet to prevent the leaked liquid from flowing to the battery cell 30, the control board 40 and other devices; the external air flow flows through the liquid storage tank 13 and leads to the air inlet of the atomizer 200, and the water vapor and liquid such as the leaked liquid carried by the air flow can condense on the end surface of the air inlet column 14, and even the liquid on the end surface of the bracket 10 is guided to the air inlet column 14, thereby causing the air hole 140 to have a higher risk of being blocked.

[0057] like Figure 4 As shown, the drainage structure 15 can be in a circular ring shape, and can be arranged 360 degrees around the air hole 140; the drainage structure 15 can also be arranged partially around the air hole 140, such as half-around, and the present application does not make any specific limitation on this.

[0058] Optionally, the drainage structure 15 can be a drainage slope 151 such as a chamfered right angle or a rounded angle, and the drainage structure 15 can also be a structure such as a drainage groove or a drainage hole, which can reduce the area of ​​the first end face 141 of the end of the air intake column 14 away from the bottom wall of the liquid storage tank 13, thereby reducing the amount of liquid accumulated on the first end face 141, and is also beneficial for introducing the liquid accumulated on the first end face 141 into the liquid storage tank 13, further reducing the amount of liquid accumulated on the first end face 141, and can effectively reduce the risk of liquid entering the air hole 140.

[0059] Further, when the drainage structure 15 is a drainage slope 151, the angle between the drainage slope 151 and the axis of the air hole 140 is greater than or equal to 30 degrees and less than or equal to 60 degrees, so as to increase the drainage efficiency of the drainage slope 151. Optionally, the angle between the drainage slope 151 and the axis of the air hole 140 can be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees or 60 degrees.

[0060] In this application, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0061] like Figure 5 As described above, the air hole 140 is disposed on the side wall of the air inlet column 14 , and the drainage structure 15 can also be a drainage groove and is disposed around the air hole 140 to guide the liquid flowing into the air hole 140 to the liquid storage tank 13 .

[0062] Specifically, the liquid storage tank 13 is used to store liquid that has leaked into the power supply assembly 100; the air hole 140 on the air intake column 14 is connected to the air flow sensing component 20. When the atomizer 200 is subjected to a suction operation, the air flow sensing component 20 senses the air flow changes in the electronic atomization device through the air hole 140, and feeds back a signal to the control board 40, thereby controlling the battery cell 30 to power the atomizer 200; the drainage structure 15 is used to guide the liquid gathered on one end of the air intake column 14 away from the bottom wall of the liquid storage tank 13 to the liquid storage tank 13, to prevent the end face of the air intake column 14 away from the bottom wall of the liquid storage tank 13 from accumulating excessive liquid, which can significantly reduce the risk of liquid blocking the air hole 140, thereby avoiding the air flow sensing component 20 being unable to sense air flow changes and the electronic atomization device 300 being unable to start normally.

[0063] In this embodiment, the air hole 140 is disposed at one end of the bottom wall of the air inlet column 14 away from the liquid storage tank 13, and the drainage structure 15 is a drainage slope 151 disposed around the air hole 140. For example, a right angle or a rounded corner is formed on one end of the bottom wall of the air inlet column 14 away from the liquid storage tank 13 to form the drainage slope 151.

[0064] It can be understood that the end of the air intake column 14 away from the bottom wall of the liquid storage tank 13 is chamfered, and the end of the air intake column 14 away from the bottom wall of the liquid storage tank 13 is divided into a first end face 141 and a drainage slope 151. Compared with a design without a chamfer, the drainage slope 151 can reduce the platform area of ​​the end face of the bottom wall of the air intake column 14 away from the liquid storage tank 13, thereby reducing the amount of liquid accumulated on the air intake column 14. At the same time, the liquid is also more likely to flow into the liquid storage tank 13 through the drainage slope 151, thereby reducing the risk of liquid flowing into the air hole 140.

[0065] Furthermore, the radial width of the first end face 141 of the air intake column 14 away from the bottom wall of the liquid storage tank 13 along the air hole 140 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm, which can make the air intake column 14 have a certain strength, and can also reduce the accumulation of liquid on the first end face 141, and the liquid on the air intake column 14 can easily flow into the liquid storage tank 13 through the drainage slope 151.

[0066] Optionally, the width of the first end surface 141 along the radial direction of the air hole 140 is 0.1 mm, 0.2 mm or 0.3 mm.

[0067] In other embodiments, the drainage structure 15 may also be a plurality of drainage grooves arranged around the air hole 140, with one end of the drainage groove being arranged on the end surface of the air intake column 14 away from the liquid storage tank 13, and the other end extending toward the liquid storage tank 13, for guiding the liquid on the air intake column 14 into the liquid storage tank 13.

[0068] In the description of the present application, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0069] Furthermore, an isolation groove 16 is formed between the air intake column 14 and the side wall of the liquid storage tank 13, and the isolation groove 16 is at least partially arranged around the air intake column 14. By arranging the isolation groove 16 between the air intake column 14 and the side wall of the liquid storage tank 13, the isolation groove 16 can block the liquid on the side wall of the liquid storage tank 13 from flowing into the air intake column 14 area, reducing the source of liquid around the air intake hole 140. When the isolation groove 16 is arranged completely around the air intake column 14, the isolation groove 16 can also be used to receive the liquid flowing from the side wall of the air intake column 14 and the liquid storage tank 13, which is equivalent to a secondary liquid storage tank.

[0070] Optionally, the isolation groove 16 is arranged around the air intake column 14, and the isolation groove 16 is isolated from the liquid storage tank 13, and the isolation groove 16 can store the liquid guided on the air intake column 14. The side wall of the isolation groove 16 near the liquid storage tank 13 is lower than the side walls of the air intake column 14 and the liquid storage tank 13. When the liquid contained in the isolation groove 16 is full, the liquid in the isolation groove 16 can overflow the isolation groove 16 and flow into the liquid storage tank 13.

[0071] In one embodiment, the isolation groove 16 is also connected to the liquid storage tank 13 , and the isolation groove 16 can guide the liquid contained therein into the liquid storage tank 13 , thereby preventing the liquid stored in the isolation groove 16 from overflowing and entering the air hole 140 .

[0072] Furthermore, the bottom wall of the isolation groove 16 can be a plane or a diversion sloping wall. When the bottom wall of the isolation groove 16 is a diversion sloping wall, the lowest point of the diversion sloping wall is close to the liquid storage tank 13, and the liquid in the isolation groove 16 is diverted to the liquid storage tank 13 along the diversion sloping wall, thereby increasing the liquid guiding effect of the isolation groove 16.

[0073] Furthermore, an isolation wall 17 is provided at one end of the bracket 10. The isolation wall 17 is arranged around the air intake column 14, and the isolation groove 16 is arranged between the isolation wall 17 and the air intake column 14. An opening 18 is formed on the isolation wall 17, and the isolation groove 16 is connected to the liquid storage tank 13 through the opening 18.

[0074] The isolation wall 17 can further increase the difficulty of the liquid on the end surface of the bracket 10 flowing to the pore 140, and the isolation wall 17 can also block the water vapor in the liquid storage tank 13 from flowing to the pore 140, which is beneficial to reduce the risk of the pore 140 being blocked.

[0075] Optionally, the isolation wall 17 surrounds the air intake column 14 , and when the air intake column 14 and the side wall of the liquid storage tank 13 are spaced apart, the isolation wall 17 can also be spaced apart from the side wall of the liquid storage tank 13 ; the isolation wall 17 can also be integrally formed with the side wall of the isolation tank 16 .

[0076] Optionally, the opening 18 is a through hole provided on the isolation wall 17 close to one side of the liquid storage tank 13 , and the liquid in the isolation tank 16 flows into the liquid storage tank 13 through the through hole.

[0077] In this embodiment, the opening 18 is a notch extending from the end surface of the partition wall 17 away from the bottom wall of the liquid storage tank 13 to the bottom wall of the liquid storage tank 13. Setting the opening 18 as a notch can reduce the difficulty of processing and achieve a better diversion effect.

[0078] The air inlet column 14 is at least partially embedded in the side wall of the liquid storage tank 13. The side wall of the liquid storage tank 13 is formed with a partition wall 17. The partition wall 17 includes an annular block portion 171. The annular block portion 171 extends from the side wall of the liquid storage tank 13 into the liquid storage tank 13. The annular block portion 171 is formed with an opening 18.

[0079] Specifically, the air intake column 14 is partially embedded in the side wall of the liquid storage tank 13, the isolation wall 17 is a circular ring with an opening 18, a portion of the isolation wall 17 is embedded in the side wall of the liquid storage tank 13, and the other portion of the isolation wall 17 extends into the liquid storage tank 13 to form an annular retaining portion 171, and the opening 18 connects the liquid storage tank 13 and the isolation tank 16.

[0080] In other embodiments, the air intake column 14 can also be completely embedded in the side wall of the liquid storage tank 13, and the isolation wall 17 is arranged around the air intake column 14, and the isolation wall 17 has an opening 18 on the side facing the liquid storage tank 13 for introducing the liquid in the isolation groove 16 into the liquid storage tank 13.

[0081] Combination Figure 6 At least one air inlet 131 is provided on the side wall of the liquid storage tank 13, wherein at least one air inlet 131 is arranged at a position where an air inlet column 14 is embedded in the side wall of the liquid storage tank 13, so that when the outside air flows into the liquid storage tank 13 through the air inlet 131, it will directly pass through the air inlet column 14, so that the air hole 140 can detect the airflow condition more directly and efficiently.

[0082] For example, when the side wall of the liquid storage tank 13 is provided with an air inlet 131, the air inlet 131 is arranged at the position where the air inlet column 14 is embedded in the side wall of the liquid storage tank 13. When the side wall of the liquid storage tank 13 is provided with two air inlets 131, one of the air inlets 131 is arranged at the position where the air inlet column 14 is embedded in the side wall of the liquid storage tank 13, and the other air inlet 131 can be arranged symmetrically with the first air inlet 131, or can be arranged at other positions of the side wall of the liquid storage tank 13, which is not limited here.

[0083] Specifically, when the atomizer 200 is subjected to a suction operation, the outside air enters the electronic atomization device 300 through the air inlet 131, and then flows into the atomizer 200 through the liquid storage tank 13. Therefore, by setting the air inlet 131 at the position where the air inlet column 14 is embedded in the side wall of the liquid storage tank 13, the outside air first passes through the air hole 140, and then flows into the liquid storage tank 13 and the atomizer 200. Compared with opening the air inlet 140 at other positions on the side wall of the liquid storage tank 13, it can prevent the outside air from first passing through the liquid storage tank 13, carrying more water vapor, and then flowing through the air hole 140, and depositing in the area around the air hole 140, blocking the air hole 140, thereby causing the air flow sensor 20 to be unable to detect air flow changes, and the electronic atomization device 300 cannot start normally.

[0084] Furthermore, at least one air inhalation hole 51 is provided on the housing 50, and the air inhalation hole 51 is used to conduct external air into the electronic atomization device 300. It can be understood that the at least one air inhalation hole 51 is provided in a one-to-one correspondence with the at least one air inlet 131, which can reduce the suction resistance of the electronic atomization device 300.

[0085] In this embodiment, the first end surface 141 of the air inlet column 14 is higher than the second end surface 172 of the isolation wall 17, wherein the second end surface 172 is the end surface of the isolation wall 17 away from the bottom wall of the liquid storage tank 13, which can prevent the liquid in the isolation tank 16 from overflowing into the air hole 140.

[0086] And when the user takes a puff, the isolation wall 17 can block the gas flowing from the liquid storage tank 13 area to the air hole 140, thereby removing at least part of the water vapor carried by the air flow, and facilitating the condensation of water vapor on the isolation wall 17, effectively reducing the water vapor carried by the air flow flowing to the air inlet column 14, and further reducing the condensation of water vapor on the first end surface 141, which is beneficial to reducing the risk of liquid blocking the air hole 140.

[0087] Furthermore, the height difference between the first end surface 141 and the second end surface 172 is in the range of 0.2 mm to 0.4 mm. Within this range, the isolation wall 17 can play a good role in blocking water vapor from flowing toward the intake column 14 .

[0088] For example, the height difference between the first end surface 141 and the second end surface 172 may be 0.2 mm, 0.3 mm, or 0.4 mm.

[0089] In this embodiment, the first end surface 141 is lower than the third end surface 133 of the side wall of the liquid storage tank 13 , wherein the third end surface 133 is the end surface of the side wall of the liquid storage tank 13 away from the bottom wall of the liquid storage tank 13 , and the third end surface 133 can be used to abut the atomizer 200 .

[0090] It can be understood that the first end face 141 is lower than the third end face 133, and the first end face 141 is higher than the second end face 172, that is, when the atomizer 200 is connected to the power supply assembly 100, the end of the atomizer 200 close to the bracket 10 abuts against the third end face 133, which can avoid interference between the abutting surfaces of the air intake column 14 and the abutting surfaces of the atomizer 200, and further, the gap between the first end face 141 and the abutting surfaces of the atomizer 200 can be used to detect the airflow condition.

[0091] See also Figure 7 , Figure 7 yes Figure 3 The partial structural cross-sectional view along line BB when the bracket is connected to the atomizer shown in the figure shows that the height difference between the third end face 133 and the first end face 141 is in the range of 0.06 mm to 0.1 mm, which can reduce the air cut-off distance C of the air hole 140, thereby facilitating the reduction of the formation of aerosol condensate in the air hole 140.

[0092] Specifically, the aerosol of the atomizer 200 easily overflows into the liquid storage tank 13. If the height difference between the third end surface 133 and the first end surface 141 is large, that is, the air cut-off distance between the air hole 140 and the abutting surface of the atomizer 200 is also large, it is easy for the aerosol to flow to the air hole 140 and condense in the air hole 140, resulting in blocking the air hole 140. That is, within this numerical range, the air cut-off distance of the air inlet column 14 can be made small, which can detect the air flow condition and prevent a large amount of aerosol from flowing to the air hole 140, effectively reducing the formation of condensate in the air hole 140.

[0093] For example, the height difference between the third end surface 133 and the first end surface 141 may be 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm.

[0094] The bracket 10 provided in the present application has an air intake column 14 with a drainage slope 151, an isolation wall 17 and an isolation groove 16 at one end of the bracket 10, thereby forming a moat structure around the air intake column 14. Through the moat structure, the source of liquid flowing to the air intake column 14 is reduced, and the path for the liquid to enter the air hole 140 is isolated, which significantly reduces the risk of blockage of the air hole 140 and can ensure the normal startup of the electronic atomization device 300.

[0095] Furthermore, the second end face 172 of the isolation wall 17 is set lower than the first end face 141 of the air inlet column 14, and the height difference between the first end face 141 and the second end face 172 is in the range of 0.2mm to 0.4mm; the first end face 141 is set lower than the third end face 133 of the side wall of the liquid storage tank 13, and the height difference between the third end face 133 and the first end face 141 is in the range of 0.06mm to 0.1mm, that is, the distance between the air inlet column 14 and the atomizer 200 is 0.06mm-0.1mm; when the atomizer 200 is subjected to a suction operation, the aerosol can be effectively blocked from entering the air inlet column 14 area, and the airflow sensor 20 detects the flow state of the air supplemented by the outside through the air hole 140, thereby significantly reducing the formation of condensate in the air hole 140.

[0096] It can be understood that the inventive concept of the moat structure in the present application can also be applied to other fields. As long as it is possible to avoid liquids, condensates, etc. from blocking the channels in the central area, the setting method provided in the present application can be used to achieve the purpose.

[0097] Different from the prior art, the present application also provides an electronic atomization device. In the electronic atomization device, a liquid storage tank and an air inlet column are provided at one end of the bracket, the air inlet column is provided with an air hole, the air hole fluid is connected to the liquid storage tank, and a drainage structure is provided at one end of the air inlet column away from the bottom wall of the liquid storage tank, the drainage structure is arranged around the air hole, and the drainage structure is used to drain the liquid to the liquid storage tank, thereby reducing the amount of liquid accumulated around the air inlet column and guiding the liquid from the end of the air inlet column to the liquid storage tank, effectively reducing the risk of liquid blocking the air hole.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
