Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] This application provides an electronic atomization device 300, see Figures 1 to 4 , Figure 1 This is a structural diagram of an embodiment of the electronic atomization device provided by this application. Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure of the atomizer in the electronic atomization device, Figure 3 yes Figure 1 Schematic diagram of the explosion of the atomizer. Figure 4 yes Figure 2 A magnified schematic diagram of area A in the middle.

[0032] The electronic atomization device 300 can be used to atomize tobacco liquid. The electronic atomization device 300 includes an interconnected atomizer 100 and a main body assembly 200. The atomizer 100 is used to store tobacco liquid and atomize the tobacco liquid to form smoke for the user to inhale. The main body assembly 200 is used to power the atomizer 100 so that the atomizer 100 can atomize the tobacco liquid to form smoke.

[0033] like Figure 2 As shown, the atomizer 100 generally includes an atomizing sleeve 10 , a mounting seat 20 , an atomizing core 30 , a sealing member 40 and a base 50 .

[0034] The atomizing sleeve 10 includes a liquid storage cavity 11 , which has a liquid storage cavity 12 . The atomizing sleeve 10 also includes an air duct 14 disposed therein. The liquid storage cavity 12 is used to store e-liquid, and the air duct 14 is used to guide the smoke into the user's mouth.

[0035] like Figure 2 and Figure 4 As shown, the mounting base 20 includes a shell 21 and a partition 22 disposed in the shell 21 . The partition 22 has a through hole 220 . The through hole 220 communicates with the liquid storage cavity 11 , that is, the through hole 220 communicates with the liquid storage cavity 12 .

[0036] In this embodiment, a partition 22 divides the space within the housing 21 into a liquid inlet chamber 23 and an access chamber 24. The liquid inlet chamber 23 and the access chamber 24 are connected via the partition 22. A smoke outlet 25 is also provided on the housing 21 on the same side as the liquid inlet chamber 23. The mounting base 20 is embedded in the atomizing sleeve 10, and the vent tube 14 is connected to the smoke outlet 25 to direct the smoke through the smoke outlet 25 and the vent tube 14 to the user's mouth.

[0037] In other embodiments, the partition 22 may be connected to the end of the housing 21 facing the liquid storage chamber 11, thereby eliminating the need for the partition 22 to form a liquid inlet chamber 23 with the housing 21; or, the partition 22 may be connected to the end of the housing 21 facing away from the liquid storage chamber 11, thereby eliminating the need for the partition 22 to form an access chamber 24 with the housing 21. This application does not limit the specific structure of the mounting base 20. The following description of the mating relationship between the mounting base 20, the atomizer core 30, and the sealing member 40 is applicable to various variations of the mounting base 20 structure.

[0038] In other embodiments, the mounting base 20 may not be embedded in the atomizing sleeve 10, but only requires the through hole 220 to be connected to the liquid storage cavity 11. For example, the liquid storage cavity 11 is a flexible liquid storage tank, a liquid storage ball, etc., which is connected to the partition 22 and the liquid storage cavity 12 is connected to the through hole 220.

[0039] The partition 22 can be a plate with a through hole 220 in the middle, or a plate with multiple through holes 220 in the middle. It only needs to be connected to the liquid storage cavity 11 through the through hole 220 on the partition 22. This application does not impose any restrictions on this.

[0040] Continue reading Figure 2 and Figure 4 The atomizer core 30 is assembled in the access cavity 24 and blocks the liquid inlet cavity 23, and the atomizer core 30 is communicated with the liquid inlet cavity 23, so that the atomizer sleeve 10, the mounting base 20 and the atomizer core 30 form a liquid storage space, and the liquid storage space stores the tobacco oil. The liquid inlet cavity 23 and the through hole 220 guide the tobacco oil to the atomizer core 30, so that the atomizer core 30 atomizes the tobacco oil to form smoke, and then the smoke is guided to the user's mouth through the smoke outlet 25 and the ventilation tube 14.

[0041] The seal 40 is located on the side of the partition 22 facing away from the liquid storage chamber 11 and between the partition 22 and the atomizer core 30. The atomizer core 30 presses against the seal 40 to prevent liquid leakage. The seal 40 has an opening 42 that communicates with the through hole 220. Thus, the opening 42 connects to the liquid storage chamber 11, and the liquid enters the atomizer core 30 through the opening 42.

[0042] like Figure 2 and Figure 3 As shown, the base 50 is connected to and covers the end of the mounting seat 20 facing away from the atomizer sleeve 10, and the base 50 abuts the atomizer core 30, so that the atomizer core 30 abuts the seal 40, and the space formed by the mounting seat 20, the atomizer core 30 and the base 50 constitutes an atomizer chamber 51. The atomizer core 30 atomizes the e-liquid and forms smoke in the atomizer chamber 51, and the atomizer chamber 51 is communicated with the smoke outlet 25.

[0043] An electrode is also connected to the base 50, which is electrically connected to the atomizer core 30 to supply power to the atomizer core 30. A vent hole 53 is provided on the bottom wall of the base 50 away from the mounting seat 20, which is connected to the atomizer chamber 51. The vent hole 53 connects the atomizer chamber 51 and the atmosphere.

[0044] The user draws in the electronic atomization device 300 , and the atomizer core 30 atomizes the e-liquid. As the user draws in, the outside air enters the atomization chamber 51 through the vent 53 , and carries the smoke in the atomization chamber 51 through the smoke outlet 25 and the vent tube 14 to the user's mouth.

[0045] In this application, reference is made to Figures 4 to 7 A ventilation groove 26 is provided between the mounting base 20 and the sealing member 40 , and the ventilation groove 26 connects the liquid storage cavity 11 and the external atmosphere. After the liquid storage space is filled with smoke oil, the smoke oil seals the ventilation groove 26 .

[0046] The ventilation groove 26 can connect the atomizing chamber 51 and the liquid storage chamber 12, and further connect the liquid storage chamber 12 and the external atmosphere through the atomizing chamber 51. Alternatively, the atomizing sleeve 10 is provided with a through hole, and the ventilation groove 26 connects the through hole and the liquid storage chamber 12, and the through hole is connected to the external atmosphere.

[0047] As the liquid in the liquid storage chamber 12 is consumed, if the liquid storage chamber 12 is not replenished with gas, the air pressure in the liquid storage chamber 12 will continue to decrease. When the air pressure in the chamber drops to a certain level, the liquid will not be able to flow smoothly, resulting in insufficient liquid supply to the atomizer core 30, which can easily produce a burnt smell and reduce the efficiency of smoke production, ultimately giving the user a poor smoking experience. Alternatively, when the atomizer core 30 atomizes the liquid, the air in the liquid storage chamber 12 is heated, causing the air pressure in the chamber to increase. The excessive air pressure in the liquid storage chamber will cause the liquid to leak outward from the various connections. These factors will significantly reduce the quality of the electronic atomizer device 300.

[0048] Therefore, the present application provides a ventilation groove 26 between the mounting base 20 and the sealing member 40, and the ventilation groove 26 connects the liquid storage chamber 12 and the external atmosphere, so that the air pressure and hydraulic pressure in the liquid storage chamber 12 and the capillary tension and resistance of the ventilation groove 26 on the e-liquid and the atmospheric pressure are dynamically balanced by adjusting the e-liquid stored in the ventilation groove 26, thereby avoiding the occurrence of liquid discharge and leakage in the atomizer 100, and improving the quality of the atomizer 100.

[0049] Specifically, when the pressure in the liquid storage chamber 12 drops to a negative pressure threshold, outside air can enter the liquid storage chamber 12 through the ventilation groove 26 to achieve ventilation, thereby increasing the pressure in the liquid storage chamber 12. This prevents the occurrence of poor liquid flow caused by excessively low pressure in the chamber, thereby improving the quality of the atomizer 100. When the pressure in the liquid storage chamber 12 increases due to heating, more e-liquid enters the ventilation groove 26, thereby appropriately reducing the pressure in the liquid storage chamber 12, preventing leakage, and similarly improving the quality of the atomizer 100.

[0050] In one embodiment, if Figure 5 As shown, the ventilation groove 26 is provided on the side of the partition 22 facing away from the liquid storage chamber 11, and the ventilation groove 26 is covered by the sealing member 40, leaving only the ventilation port communicating with the through hole 220 and the air inlet communicating with the atomization chamber 51 exposed.

[0051] Since the ventilation grooves 26 are all located on the side of the partition 22 away from the liquid storage chamber 11, the oil in the ventilation grooves 26 has a relatively uniform hydraulic pressure, thereby reducing the risk of leakage due to excessive oil hydraulic pressure in the ventilation grooves 26.

[0052] The ventilation groove 26 can be arranged in a circuitous manner on the partition 22 to increase the length and increase the space for storing tobacco liquid. The ventilation groove 26 can also be arranged in a straight line, as long as the ventilation groove 26 can connect the through hole 220 and the atmosphere. This application does not limit this.

[0053] The ventilation grooves 26 can also be provided in multiple lines. The multiple ventilation grooves 26 can simultaneously perform ventilation to increase the air pressure in the liquid storage chamber 12. The multiple ventilation grooves 26 can also simultaneously allow liquid to flow in to reduce the air pressure in the liquid storage chamber 12. Therefore, the multiple ventilation grooves 26 can increase the convenience of adjusting the air pressure in the liquid storage chamber 12, so that the air pressure in the liquid storage chamber 12 can be quickly adjusted. The ventilation groove 26 can also be provided in one line. The present application does not limit the number of ventilation grooves 26.

[0054] A cache groove 27 is also provided on the side of the partition 22 facing away from the liquid storage chamber 12. The ventilation groove 26 flows through the cache groove 27. The cross-sectional area of ​​the cache groove 27 along the path direction of the ventilation groove 26 is larger than the cross-sectional area of ​​the ventilation groove 26 in the same direction. The seal 40 covers the ventilation groove 26 and the cache groove 27 to prevent the ventilation groove 26 and the cache groove 27 from leaking.

[0055] The buffer groove 27 is used to buffer the e-liquid, and the cross-sectional area of ​​the buffer groove 27 along the path direction of the ventilation groove 26 is larger than the cross-sectional area of ​​the ventilation groove 26 in the same direction, thereby improving the liquid storage capacity of the ventilation groove 26 to prevent the e-liquid from leaking from the ventilation groove 26.

[0056] After research, it was found that the depth of the ventilation groove 26 should be set to 0.1mm to 0.5mm, the width of the ventilation groove 26 in the direction perpendicular to its path direction should be set to 0.1mm to 0.5mm, and the width of the cache groove 27 is greater than the width of the ventilation groove 26, and the depth of the cache groove 27 is greater than or equal to the depth of the ventilation groove 26.

[0057] See Figures 6 to 9 The atomizer core 30 squeezes the seal 40 to create an end-face seal, allowing e-liquid to flow only through the ventilation groove 26. A simulation analysis was conducted on a structure where the ventilation groove 26 is located on the side of the partition 22 facing away from the liquid storage chamber 11 to investigate the relationship between the extrusion deformation of the seal 40 and the width of the ventilation groove 26.

[0058] Analysis revealed that when the depth of the ventilation groove 26 is less than 0.1mm or the width of the ventilation groove 26 is less than 0.1mm, the capillary tension of the ventilation groove 26 on the e-liquid is too great, making ventilation difficult and hindering the regulation of air pressure within the liquid storage chamber 12. As the width of the ventilation groove 26 gradually increases from 0.1mm to 0.5mm, the extrusion deformation of the seal 40 corresponding to the ventilation groove 26 gradually increases. When the depth of the ventilation groove 26 is greater than 0.5mm or the width of the ventilation groove 26 is greater than 0.5mm, the capillary tension of the ventilation groove 26 on the e-liquid is too small, making the ventilation groove 26 prone to leakage. Furthermore, when the seal 40 covers the ventilation groove 26, it deforms and squeezes too much space in the ventilation groove 26, and there is also a risk of blocking the ventilation groove 26, hindering the regulation of air pressure within the liquid storage chamber 12.

[0059] Therefore, the depth of the ventilation groove 26 is 0.1mm to 0.5mm, and the width of the ventilation groove 26 is 0.1mm to 0.5mm, which can not only ensure that the capillary tension of the ventilation groove 26 on the e-liquid is appropriate, but also prevent the seal 40 from blocking the ventilation groove 26, thereby facilitating the adjustment of the air pressure of the liquid storage chamber 12 through the ventilation groove 26 and the buffer groove 27, and avoiding the occurrence of leakage and poor liquid discharge of the atomizer 100.

[0060] In this embodiment, the partition plate 22 is provided with a through hole 220, which connects the liquid storage chamber 12 and the atomizer core 30. The partition plate 22 is provided with two ventilation grooves 26, which are adjacent to each other end to end and are arranged around the through hole 220 of the partition plate 22. The two ventilation grooves 26 have the same length.

[0061] Specifically, the air inlet of one ventilation groove 26 is adjacent to the air inlet of another ventilation groove 26, and the air inlet of the ventilation groove 26 is adjacent to the air inlet of the other ventilation groove 26, and the two ventilation grooves 26 are arranged around the through hole 220, the ventilation port is connected to the liquid storage chamber 12, and the air inlet is connected to the atmosphere, so that the ventilation groove 26 has a longer length, can store more e-liquid, and can also conveniently adjust the air pressure in the liquid storage chamber 12, and the ventilation ports of the two ventilation grooves 26 are arranged in different positions, which can avoid the bubbles generated by the ventilation ports in the same place from aggregating and increasing the difficulty of liquid discharge.

[0062] The length and cross-sectional area of ​​the ventilation groove 26 and the length and cross-sectional area of ​​the buffer groove 27 can be set according to the specifications of the atomizer 100 to facilitate adjusting the air pressure in the liquid storage chamber 12.

[0063] In this embodiment, Figure 10 As shown, the sealing member 40 includes a sealing ring gasket 41 and two isolation gaskets 43 respectively provided at opposite ends of the sealing ring gasket 41. The sealing ring gasket 42 has an opening 42. The isolation gaskets 43 press against the shell 21. The air inlet of the ventilation groove 26 is exposed from the sealing ring gasket 41 and is offset from the isolation gasket 43, so that the air inlet of the ventilation groove 26 is connected to the atomization chamber 51 and further connected to the atmosphere.

[0064] In other embodiments, a ventilation groove 26 is provided on the shell 21 located on the side of the partition 22 away from the liquid storage chamber 11, and the ventilation port of the ventilation groove 26 is provided on the partition 22 to communicate with the liquid storage chamber 12, the seal 40 covers the ventilation groove 26, and the air inlet of the ventilation groove 26 is connected to the atmosphere.

[0065] A buffer slot 27 may also be provided on the path of the ventilation slot 26 , and the ventilation slot 26 flows through the buffer slot 27 . The description of the specifications and dimensions of the ventilation slot 26 and the buffer slot 27 in the above embodiment is also applicable to this embodiment and will not be repeated here.

[0066] In other embodiments, see Figure 11 The sealing member 40 is provided with a ventilation groove 26 . Specifically, the ventilation groove 26 is provided on the side of the sealing member 40 facing the partition 22 and / or on the side of the sealing member 40 facing the atomizing core 30 , or the ventilation groove 26 can also be provided in the sealing member 40 .

[0067] For example, six ventilation grooves 26 are provided on the side of the sealing member 40 facing the partition 22 and / or the side of the sealing member 40 facing the atomizer core 30 , which can extremely conveniently adjust the air pressure in the liquid storage chamber 12 .

[0068] See also Figures 5 to 9 and Figure 11Relatively speaking, the seal 40 is greatly deformed by extrusion. When a ventilation groove 26 is provided on the seal 40, the ventilation groove 26 is easily cut off by the extrusion and deformation of the seal 40, so its ventilation effect is worse than that of the ventilation groove 26 provided on the partition 22. If the specification size of the ventilation groove 26 is increased to improve the ventilation effect of the ventilation groove 26 provided on the seal 40, it is considered that the force on the seal 40 may be uneven, resulting in a large amount of extrusion deformation of some ventilation grooves 26, which makes the ventilation effect of the ventilation groove 26 poor, and a small amount of extrusion deformation of some ventilation grooves 26 makes the ventilation groove 26 prone to leakage. Therefore, in general, the solution of providing the ventilation groove 26 on the partition 22 is better than the solution of providing the ventilation groove 26 on the seal 40 in all aspects.

[0069] Alternatively, in some embodiments, in conjunction with Figure 4 、 Figure 5 and Figure 11 The side of the partition 22 facing away from the liquid storage chamber 12 is provided with a ventilation groove 26, and the sealing member 40 is also provided with a ventilation groove 26. For example, the side of the partition 22 facing away from the liquid inlet chamber 23 is provided with a ventilation groove 26, and the side of the sealing member 40 facing the partition 22 is provided with another ventilation groove 26. The two ventilation grooves 26 are arranged in different positions relative to each other, thereby effectively increasing the number of ventilation grooves 26 that can be set, thereby increasing the convenience of adjusting the air pressure in the liquid storage chamber 12 and preventing liquid leakage; alternatively, the two ventilation grooves 26 are arranged in opposite positions, thereby reducing the groove depth of the ventilation grooves 26 set on the partition 22 and the sealing member 40, effectively ensuring that the strength of the partition 22 is not greatly damaged by the ventilation grooves 26, and the value obtained by adding the groove depths of the two oppositely arranged ventilation grooves 26 is 0.1mm to 0.5mm.

[0070] In addition, the ventilation groove 26 can also be provided on the side of the seal 40 facing away from the partition 22, or the ventilation groove 26 can be provided on both the side of the seal 40 facing the partition 22 and the side of the seal 40 facing the atomizer core 30, or the ventilation groove 26 can also be provided in the seal 40, which is not limited in this application.

[0071] Different from the prior art, the present application discloses an atomizer and an electronic atomization device. In the present application, a ventilation groove is provided between the mounting seat and the sealing member, and the ventilation groove connects the liquid storage cavity and the external atmosphere. This allows the air pressure and hydraulic pressure in the liquid storage cavity to reach a dynamic balance with the capillary tension and resistance of the ventilation groove on the smoke liquid and the atmospheric pressure by adjusting the smoke liquid stored in the ventilation groove. Furthermore, when the air pressure in the liquid storage cavity of the atomizer is too low, outside air can enter the liquid storage cavity through the ventilation groove, thereby increasing the air pressure in the liquid storage cavity, thereby avoiding the problem of poor liquid discharge caused by too low air pressure in the cavity, thereby improving the quality of the atomizer.

[0072] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. 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.
