Description

Technical Field

[0002] The atomizing device is usually capable of heating and atomizing the atomizing matrix to produce an aerosol, and the atomizing device has a liquid storage tank for storage.

At the same time, during normal use, it is easy for the atomizing matrix to not flow smoothly due to excessive negative pressure in the liquid storage tank, which will cause the atomizer to burn dry and cause a burnt taste.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0038] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0039] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0040] The atomizing device includes an atomizer and a power supply assembly. The atomizer and the power supply assembly can be an integral structure or a detachable split structure. The power supply assembly can supply power to the atomizer, and the atomizer can heat the atomized matrix to form an aerosol under the action of electric energy. The atomizer includes an atomizing assembly and a liquid storage tank. The liquid storage tank stores the atomized matrix. The atomizing assembly includes an atomizing tube, a liquid guide and a heating element. The liquid storage tank is usually provided with an atomizing pipeline. One end of the atomizing pipeline can pass through the atomizer, and the other end can be sealed and connected to the atomizing tube. The liquid guide and the heating element are both arranged inside the atomizing tube, and the liquid guide wraps the heating element. The liquid guide can guide the atomized matrix in the liquid storage tank to the heating element. In a specific embodiment, the power supply assembly provides electric energy to the heating element, and the atomized matrix can be heated and atomized by the heating element.

[0041] If the internal air pressure of the liquid storage tank and the external atmospheric pressure change greatly due to changes in ambient temperature, the atomized matrix will leak through the liquid inlet hole on the liquid storage tank-the liquid guide piece-the atomization pipeline.

[0042] For the above problems, the following two solutions are commonly used:

[0043] First, by increasing the amount of atomizing matrix in the liquid storage tank and reserving bubbles in the atomizing matrix, this method can effectively alleviate the above problems. However, if the negative pressure in the liquid storage tank is too large, the bubbles will shrink, which can easily cause trapped air during use, resulting in poor liquid flow and causing the problem of dry burning and burnt smell.

[0044] Second, a ventilation groove is made inside the liquid storage tank to connect the internal pressure of the liquid storage tank with the external atmospheric pressure. The pressure difference between the inside and outside of the liquid storage tank can be balanced by adding air, which can solve the problem of trapped air. However, in the subsequent use process, it is easy to cause the liquid to drain too quickly and cause splashing.

[0045] The above two solutions still lead to problems such as air entrapment and slow liquid delivery during use, which easily cause dry burning smell, so the solution shown in the following embodiment is proposed.

[0046] See also Figure 1-Figure 8 As shown, the atomizer provided in this embodiment includes: a chamber body 10 , a sealing movable part 20 and a liquid outlet assembly 12 .

[0047] The warehouse body 10 is provided with a pressure relief hole 11, which is connected to the outside atmosphere. The sealing movable part 20 is slidably and sealingly connected in the warehouse body 10, and the warehouse body 10 has a liquid storage cavity 102 for storing atomized matrix. The liquid storage cavity 102 is formed on the side of the warehouse body 10 away from the pressure relief hole 11 of the sealing movable part 20.

[0048] It should be noted that the sealing movable part 20 is sealingly connected in the warehouse body 10 in a sliding manner. In other words, the sealing movable part 20 can slide back and forth in the warehouse body 10 and is sealingly connected to the inner wall of the warehouse body 10. The liquid storage tank 101 is arranged on the side of the warehouse body 10 away from the pressure relief hole 11 of the sealing movable part 20. It can be understood that the pressure relief hole 11 is arranged at one end of the sliding direction of the sealing movable part 20.

[0049] In order to ensure that the sealing movable member 20 can slide back and forth in the bin body 10, the bin body 10 preferably adopts a hard bin body structure made of plastic material.

[0050] In order to improve the sealing performance, the sealing movable part 20 is preferably made of a soft plastic material such as polypropylene (PP) or low-density polyethylene (LDPE). The sealing movable part 20 can seal the gap between itself and the inner wall of the warehouse body 10 during the reciprocating sliding process in the warehouse body 10.

[0051] The liquid outlet assembly 12 is disposed at one end of the chamber body 10 away from the sealing movable member 20 . The liquid outlet assembly 12 is communicated with the liquid storage chamber 102 and is used for outputting the atomized matrix.

[0052] In a specific embodiment, the atomized matrix output by the liquid outlet component 12 can be heated and atomized into an aerosol by the atomization component, and the liquid outlet component 12 is arranged at a position at one end of the chamber 10 close to the liquid storage chamber 102 opposite to the position where the pressure relief hole 11 is arranged.

[0053] In some embodiments, along the sliding direction of the sealing movable member 20, the pressure relief hole 11 and the liquid outlet assembly 12 are respectively located at two ends of the chamber body 10, so as to Figure 1 Taking the perspective shown as an example, the bin body 10 is arranged in a vertical direction, the pressure relief hole 11 is located at the top of the bin body 10 , and the liquid outlet assembly 12 is at the bottom of the bin body 10 .

[0054] In this way, the sealing movable part 20 can be set inside the warehouse body 10 to slide back and forth in the direction from the pressure relief hole 11 to the liquid outlet component 12. In other words, the sealing movable part 20 can slide inside the warehouse body 10 along the direction from the pressure relief hole 11 to the liquid outlet component 12, or the sealing component 20 can slide inside the warehouse body 10 along the direction from the liquid outlet component 12 to the pressure relief hole 11.

[0055] In this embodiment, the area inside the housing 10 from the sealing movable part 20 to the liquid outlet assembly 12 is a liquid storage chamber 102 for storing the atomized matrix, and the liquid outlet assembly 12 can output the atomized matrix to the atomizing assembly.

[0056] It should be noted that the atomization matrix is ​​usually in liquid form. In this embodiment, the atomization matrix is ​​an aerosol generating matrix that can generate an aerosol by heating and atomization, for example, tobacco oil, etc. After being output through the liquid outlet component 12, the atomization matrix can be output to the atomization component for atomization. For the specific liquid outlet method and atomization method, please refer to the subsequent embodiments.

[0057] When the atomizer is subjected to a change in the external atmospheric pressure, the internal pressure of the liquid storage chamber 102 changes relative to the external atmospheric pressure, and the sealing movable part 20 can slide according to the change in the liquid storage chamber 102 relative to the external atmospheric pressure, thereby adjusting the internal pressure of the liquid storage chamber 102.

[0058] Under normal circumstances, the pressure of the outside atmosphere and the liquid storage chamber 102 are maintained at a constant state. During the storage or transportation of the atomizer, as the outside environment temperature changes, the outside atmospheric pressure changes, and the inside of the liquid storage chamber 102 changes relative to the constant state, and the sealing movable member 20 slides to the side where the pressure decreases, and stops moving when the outside atmospheric pressure is the same or substantially the same as the pressure inside the liquid storage chamber 102, so as to balance the pressure of the outside atmosphere and the pressure inside the liquid storage chamber 102 and prevent leakage of the atomized matrix.

[0059] Specifically, for example, as the temperature of the external environment increases, the pressure of the external atmosphere increases, while the pressure inside the liquid storage chamber 102 decreases relatively, and the sealing movable part 20 moves toward one side of the liquid storage chamber 102 from the pressure relief hole 11 to the liquid outlet assembly 12, which is equivalent to compressing and increasing the pressure inside the liquid storage chamber 102. When the pressure inside the liquid storage chamber 102 is the same or substantially the same as the pressure of the external atmosphere, the sealing movable part 20 stops moving to balance the pressure of the external atmosphere and the pressure inside the liquid storage chamber 102. As the temperature of the external environment decreases, the sealing movable part 20 slides in the opposite direction until it stops moving.

[0060] In the above embodiment, the sealing movable part 20 slides toward the side where the pressure decreases as the pressure changes, which can balance the liquid storage chamber 102 and the external atmospheric pressure. On the one hand, leakage of the liquefied matrix can be avoided, and on the other hand, the liquefied matrix will not produce trapped air. After the pressure stabilizes, the atomized matrix is ​​output smoothly without causing the problem of dry burning smell. At the same time, the problem of splashing when the atomized matrix is ​​output can be further avoided.

[0061] In this embodiment, the interior of the silo 10 forms a pressure relief chamber 101 together with the sealing movable part 20 and the inner wall of the silo 10 near the pressure relief hole. The pressure relief chamber 101 is communicated with the pressure relief hole 11 .

[0062] As the sealing movable part 20 slides toward the pressure relief chamber 102, a cavity is formed inside the chamber body 10 from the sealing movable part 20 to the pressure relief hole 11. The cavity is the pressure relief chamber 101, and the pressure of the pressure relief chamber can change when the external atmospheric pressure changes.

[0063] It should be noted that the pressure relief chamber 101 does not exist when the sealing movable part 20 slides to fit the cavity wall of the inner cavity 100 where the pressure relief hole 11 is set. In other words, the size of the pressure relief chamber 101 and the size of the liquid storage chamber 102 change relative to each other.

[0064] The pressure relief hole 11 is connected to the pressure relief chamber 101, so that the pressure relief chamber 101 can be connected to the outside atmosphere through the pressure relief hole 11. When the pressure inside the pressure relief chamber 101 and the liquid storage chamber 102 changes, the sealing movable member 20 can move to the side chamber with reduced pressure.

[0065] Specifically, under normal circumstances, the pressure of the pressure relief chamber 101 and the liquid storage chamber 102 is maintained at a constant state. During the storage or transportation of the atomizer, as the external environment temperature changes, the pressure of the pressure relief chamber 101 changes, and the sealing movable member 20 moves from the chamber with increased pressure in the pressure relief chamber 101 and the liquid storage chamber 102 to the chamber with reduced pressure, and stops moving when the pressure inside the two chambers is the same or substantially the same, so as to balance the pressure inside the two chambers and prevent leakage of the atomized matrix.

[0066] For example, as the temperature of the external environment increases, the pressure inside the pressure relief chamber 101 increases, while the pressure inside the liquid storage chamber 102 decreases relatively, and the sealing movable part 20 moves from the pressure relief chamber 101 to the liquid storage chamber 102, which is equivalent to compression and increases the pressure inside the liquid storage chamber 102. When the pressure inside the liquid storage chamber 102 is the same or substantially the same as the pressure inside the pressure relief chamber 101, the sealing movable part 20 stops moving to balance the pressure inside the pressure relief chamber 101 and the liquid storage chamber 102. As the temperature of the external environment decreases, the sealing movable part 20 moves in the opposite direction until it stops moving.

[0067] In one embodiment of the present application, the liquid outlet component 12 may be an open port or hole, and is connected to the atomizing component, and may output the atomized matrix into the atomizing component. In this case, the atomizer and the atomizing component form an integrated structure.

[0068] It should be noted that in the above-mentioned embodiment, a corresponding sealing structure needs to be provided at the open mouth or hole, and the sealing structure can seal the open mouth or hole. The sealing structure has a liquid storage component inside, and the liquid storage component can slowly release the atomized matrix to the atomization component. For the specific structure of the sealing structure, please refer to the subsequent embodiments.

[0069] As the amount of atomized matrix stored in the liquid storage chamber 102 changes, the pressure inside the liquid storage chamber 102 also changes accordingly. For example, when the liquid storage chamber 102 discharges the atomized matrix through the liquid outlet assembly 12, the pressure inside the liquid storage chamber 102 decreases, and at this time, the sealing movable member 20 slides inside the warehouse body 10 from the pressure relief chamber 101 to the liquid storage chamber 102; when the atomized matrix is ​​added to the liquid storage chamber 102, the pressure inside the liquid storage chamber 102 increases, and at this time, the sealing movable member 20 moves from the liquid storage chamber 102 to the pressure relief chamber 101.

[0070] In the above embodiment, the pressure inside the pressure relief chamber 101 can be changed under the action of the pressure relief hole 11. As the pressure inside the pressure relief chamber 101 and the liquid storage chamber 102 changes, the sealing movable part 20 can move inside the chamber body 10 to the side where the pressure in the pressure relief chamber 101 and the liquid storage chamber 102 is reduced, so as to balance the pressure inside the pressure relief chamber 101 and the liquid storage chamber 102, which can effectively avoid the problem of leakage of the atomized matrix and ensure that the atomized matrix can be smoothly discharged during subsequent use.

[0071] In this embodiment, in order to enable the generated aerosol to be discharged from the designated path, an atomizing pipe 13 is further provided inside the warehouse body 10, one end of the atomizing pipe 13 penetrates the warehouse body 10, and the other end of the atomizing pipe 13 is connected to the atomizing assembly, so that the aerosol can be output to the outside of the warehouse body 10 through the atomizing pipe 13. The sealing movable part 20 is arranged in an annular shape, and the sealing movable part 20 arranged in an annular shape is sleeved between the atomizing pipe 13 and the inner wall of the warehouse body 10, that is, the inner circumference 200 of the sealing movable part 20 arranged in an annular shape is sleeved on the outer wall of the atomizing pipe 13, and the inner circumference 200 of the sealing movable part 20 arranged in an annular shape is connected to the outer wall of the atomizing pipe 13 in a sliding and sealing manner. When the sealing movable part 20 reciprocates in the direction from the pressure relief hole 11 to the liquid outlet assembly 12 inside the warehouse body 10, the inner circumference 200 of the sealing movable part 20 synchronously reciprocates along the length direction of the atomizing pipe 13. In other words, the sliding direction of the sealing movable part 20 is the length direction of the atomizing pipe 13.

[0072] like Figure 3 , Figure 4 , Fig. 9 and Fig.10As shown, the sealing movable part 20 includes a main body 21, a first elastic part 22 and a second elastic part 23. The main body 21 is annular in shape. The first elastic part 22 is disposed around the outer peripheral side of the main body 21. The first elastic part 22 flexibly abuts against the inner wall of the bin body 10 in an interference fit manner, and then deforms inwardly along the radial direction of the main body 21 when the outer periphery of the main body 21 contacts the inner wall of the bin body 10, thereby sealing the gap between the inner wall of the bin body 10. The second elastic part 23 is disposed around the inner peripheral side of the main body 21. The second elastic part 23 flexibly abuts against the outer wall of the atomizing pipe 13 in an interference fit manner. Then, when the inner periphery of the main body 21 contacts the outer wall of the atomizing pipe 13, the second elastic part 23 deforms outwardly along the radial direction of the main body 21 when the inner periphery of the main body 21 contacts the outer wall of the atomizing pipe 13, thereby sealing the gap between the outer wall of the atomizing pipe 13.

[0073] Continue to see Figure 6 and Figure 7 As shown, the first elastic portion 22 includes a first connecting segment 221 and two first curved segments 222. The first connecting segment 221 is formed by being recessed from the outer periphery of the main body 21 in the direction toward the middle of the outer periphery of the main body 21, that is, the first connecting segment 222 is a groove arranged on the outer periphery of the main body 21, and the groove is recessed inwardly along the radial direction of the main body 21. Along the axial direction of the main body 21, the two first curved segments 222 are respectively arranged at opposite ends of the first connecting segment 221, one of the first curved segments 222 is bent and extended from one end of the first connecting segment 221 in a direction away from the side of the liquid storage chamber 102, and the other first curved segment 222 is bent and extended from the other end of the first connecting segment 221 in a direction toward the side of the liquid storage chamber 102. The two first curved segments 222 are sealed against the inner wall of the warehouse body 10 on the side facing away from the main body 21.

[0074] In one embodiment of the present application, the main body 21 has two surfaces, the groove and the two surfaces of the main body 21 form two edges respectively, and the two first curved sections 222 are respectively arranged at the two edges of the first connecting section 221. The first curved section 222 bends and extends from the edge of the first connecting section 221 along the axial direction of the main body 21 toward the outside of the main body 21, and the outside of the main body 21 is the outside of the two surfaces along its axial direction, so that the first curved section 222 forms a curved shape. The side of the first curved section 222 facing away from the main body 21 is sealed against the inner wall of the bin body 10. When squeezed by the main body 21 and the inner wall of the bin body 10, the first curved section 222 is deformed inward along the radial direction of the main body 21, thereby sealing the gap between the first curved section 222 and the inner wall of the bin body 10.

[0075] When the sealing movable part 20 slides back and forth inside the warehouse body 10, since the contact area between the first curved section 222 and the inner wall of the warehouse body 10 is smaller than that between the outer periphery of the sealing movable part 20 and the inner wall of the warehouse body 10, the damping of the reciprocating sliding of the sealing movable part 20 on the inner wall of the warehouse body 10 can be reduced.

[0076] In this embodiment, Figure 6 Taking the perspective shown as an example, the two first bending sections 222 are respectively arranged at the upper side edge and the lower side edge of the outer periphery of the sealing movable part 20, and the first bending section 222 located at the upper side edge bends upward and inward along the radial direction of the main body 21, and the first bending section 222 located at the lower side edge bends downward and inward along the radial direction of the main body 21.

[0077] The second elastic part 23 includes a second connecting section 231 and two second curved sections 232. The main body 21 is provided with a mounting hole corresponding to the atomizing pipe 13 along its axial direction. The mounting hole is the inner circumference of the sealing movable part 20, and the mounting hole is sleeved on the outer wall of the atomizing pipe 13. The second connecting section 231 is formed by being recessed from the edge of the mounting hole toward the middle of the mounting hole. Along the axial direction of the main body 21, the two second curved sections 232 are respectively arranged at the opposite ends of the second connecting section 231, one of the second curved sections 232 is bent and extended from one end of the second connecting section 231 in a direction away from the side of the liquid storage chamber 102, and the other second curved section 232 is bent and extended from the other end of the second connecting section 231 in a direction toward the side of the liquid storage chamber 102. The two second curved sections 232 are sealed against the outer wall of the atomizing pipe 13 on the side facing away from the main body 21.

[0078] In one embodiment of the present application, the second connecting section 231 is a groove arranged on the hole wall of the mounting hole of the main body 21, and the groove is recessed inwardly along the radial direction of the main body 21, and the groove and the two surfaces of the main body 21 along its axial direction respectively form two edges, and the two second curved sections 232 are respectively arranged at the two edges of the second connecting section 231. The second curved section 232 is bent and extended from the edge of the second connecting section 231 along the axial direction of the main body 21 toward the outside of the main body 21, so that the second curved section 232 forms a curved shape. The side of the second curved section 232 facing away from the main body 21 is sealed against the outer wall of the atomization pipe 13, and when squeezed by the main body 21 and the atomization pipe 12, the second curved section 232 is deformed outwardly along the radial direction of the main body 21, thereby sealing the gap between the second curved section 232 and the atomization pipe 13.

[0079] When the sealing movable part 20 slides back and forth inside the chamber body 10, since the contact area between the second curved section 232 and the atomization pipe 13 is smaller than the inner periphery of the sealing movable part 20, the damping of the reciprocating sliding of the sealing movable part 20 on the inner wall of the chamber body 10 can be reduced.

[0080] Likewise Fig. 9 Taking the perspective shown as an example, the two second bending sections 232 are respectively arranged at the upper side edge and the lower side edge of the inner circumference of the sealing movable part 20, and the second bending section 232 located at the upper side edge bends upward and outward along the radial direction of the main body 21, and the second bending section 232 located at the lower side edge bends downward and outward along the radial direction of the main body 21.

[0081] In this embodiment, the main body 21 can provide the overall strength of the sealing movable part 20, and the first curved section 222 and the second curved section 232 are arranged on the premise of reducing damping, and the sealing effect between the cavity wall of the inner cavity 100 and the outer wall of the atomization pipe 13 can be further improved by deforming under compression.

[0082] In one embodiment of the present application, the thickness of the first curved section 222 and the thickness of the second curved section 232 are both in the range of 0.2-0.8 mm, and the first curved section 222 and the second curved section 232 are thinner, so that they can undergo elastic deformation when squeezed, thereby achieving a sealing effect.

[0083] In some embodiments, the nebulizer can be applied to the nebulization device. The nebulizer can be an independent structure relative to the nebulization component and only needs to provide the nebulization matrix. For example, it only needs to be connected to the liquid guide part in the nebulization component and output the nebulization matrix to the liquid guide part.

[0084] In other embodiments, the atomizer is an integral part of the atomizing device, that is, fixedly connected to the atomizing assembly, and in some cases, the generated aerosol can be output through the atomizer. Specifically, the atomizing pipe 13 is connected to the atomizing assembly, so that the aerosol can be output to the outside of the warehouse body 10 through the atomizing pipe 13.

[0085] See also Figure 2 , Figures 5 to 8 as well as Fig.11 As shown, the atomizer provided in this embodiment also includes: an atomizing assembly 30, wherein the liquid outlet assembly 12 includes: a sealing plug 40 and a liquid storage member 50, and the warehouse body 10 is also provided with a suction nozzle 14 and an opening, and the suction nozzle 14 is connected to the air outlet end of the atomizing pipeline 13, and the generated aerosol can be discharged through the suction nozzle 14.

The sealing plug 40 is provided with a receiving chamber 41 connecting the liquid storage chamber 102 and the atomizing channel 13, and the liquid storage member 50 is arranged inside the receiving chamber 41, and the liquid storage member 50 is provided with an installation chamber 51 connecting the atomizing channel 13, and the atomizing assembly 30 is installed in the installation chamber 51 and is sealed and connected with the atomizing pipeline 13.

[0086] In one embodiment of the present application, the liquid outlet assembly 12 also includes a first sealing seat 121 and a second sealing seat 122.

The first sealing seat 121 is sealingly installed on the air inlet end of the atomization pipe 13, and the second sealing seat 122 is sealingly installed on the air inlet hole 45.

[0087] The atomization assembly 30 includes: an atomization tube 31, a liquid guide member 32 and a heating member 33. The atomization tube 31 is clamped between the first sealing seat 121 and the second sealing seat 122.

The atomization tube 31 is arranged inside the installation cavity 51, and the atomization tube 31 is sealed and connected with the atomization pipeline 13. The side wall of the atomization tube 31 is provided with an opening 311. The liquid guide member 32 wraps the heating member 33, and the liquid guide member 32 can extend to the liquid storage member 50 through the opening 311 and contact the liquid storage member 50, so that the atomized matrix can be transferred to the heating member 33 through the liquid guide member 32.

[0088] In some embodiments, the first sealing seat 121 is disposed between the atomizing tube 31 and the atomizing pipeline 13 . The first sealing seat 121 is sleeved around the periphery of the atomizing tube 31 , and the atomizing pipeline 13 is sleeved around the periphery of the first sealing seat 121 .

[0089] A through hole 123 is provided in the second sealing seat 122. The through hole 123 is arranged through the middle of the second sealing seat 122. The through hole 123 connects the atomizing tube 31 and the air inlet hole 45, thereby connecting the atomizing tube 31 with the outside atmosphere. In addition, the aperture of the through hole 123 gradually decreases from the air inlet hole 45 toward the atomizing tube 31. In this way, the passing airflow can be gathered to better impact the heating element 33, thereby improving the atomization efficiency.

[0090] During use, the atomized matrix or the generated aerosol will inevitably produce condensate and reflux. At the same time, in order to facilitate the filling of the atomized matrix, the atomizer provided in this embodiment also includes a plunger 44 and an oil suction piece 70. The sealing plug 40 also includes a accommodating chamber 46 and an oil injection hole 47. The oil injection hole 47 connects the accommodating chamber 41 and the accommodating chamber 46. The plunger 44 is sealed in the oil injection hole 43. The oil suction piece 70 is arranged in the accommodating chamber 46. The sealing plug 40 is provided with a drainage structure 48 at the position corresponding to the air inlet hole 45. The drainage structure 48 can guide the refluxed atomized matrix or condensate to the oil suction piece 70 so as to absorb the refluxed atomized matrix or condensate through the oil suction piece 70.

[0091] In this embodiment, the oil suction member 70 is also wrapped around the second sealing seat 122 , and is further provided with a communication hole 71 communicating with the outside and the through hole 123 .

[0092] The atomizer provided in this embodiment further comprises a cover plate 72, a circuit board 73 and a bottom cover 74. The cover plate 72 is arranged on a side of the sealing plug 40 away from the liquid storage chamber 102. The cover plate 72 and the sealing plug 40 enclose a receiving chamber 46. The circuit board 73 is arranged on a side of the cover plate 72 away from the oil absorption member 70. The side of the circuit board 73 away from the cover plate 72 is provided with an electrode sheet 731 (such as Figure 6 As shown), the electrode sheet 731 is electrically connected to the heating element 33, and the circuit board 73 is provided with a through hole 732 (as shown) which is connected to the air inlet 45. Figure 6 As shown), the bottom cover 74 is clamped at the opening of the bin body 10 so that the circuit board 73, the bottom cover 74 and the sealing plug 40 are limited to the inner side of the bin body 10, and the bottom cover 74 is made of magnetic or metal material.

[0093] In a specific embodiment, when the atomizer is connected to the power supply assembly, the bottom cover 74 can be quickly connected to the power supply assembly through the magnetic attraction, so that the power supply assembly provides electrical energy to the heating element 33 through the electrode sheet 731. The setting of the circuit board 73 can control the opening, closing and power of the heating element 33.

[0094] Combination Figure 8 As shown, the solid arrows pointing downward and converging toward the liquid guide 32 in the figure indicate the direction of the liquid under the atomized matrix, and the dotted arrows pointing upward in the figure indicate the direction in which the outside atmosphere is sucked in from the bottom and drives the aerosol to be discharged. In actual application, the atomized matrix flows to the liquid storage member 50 through the liquid guide groove 42, and the liquid guide 32 conducts the atomized matrix and conducts it around the heating member 33. The user inhales at the suction nozzle 14, and the outside atmosphere enters the atomization tube 31 through the connecting hole 71 and the perforation 123. When the outside atmosphere flows into the atomization tube 31 or when the user performs the suction action, the circuit board 73 triggers the heating member 33 to work. In a short period of time, while the heating member 33 heats the atomized matrix to generate aerosol, the outside gas flows, thereby discharging the aerosol from the suction nozzle 14.

[0095] This embodiment also provides an atomization device, including: the atomizer in the above embodiment, and also including: a power supply component, which is connected to the atomizer in a fixed or detachable manner and can be connected to the heating element 33 through the electrode sheet 731 to provide working power to the heating element 33 through the power supply component.

[0096] To sum up, in the atomizer and atomizing device provided by the present application, the pressure inside the liquid storage chamber can be changed under the action of the pressure relief hole. As the pressure of the external atmosphere and the pressure inside the liquid storage chamber change, the sealing movable part can slide inside the chamber body toward the side where the pressure decreases, so that the pressure inside the liquid storage chamber and the pressure of the external atmosphere reach a balance, which can effectively avoid the problem of leakage of the atomized matrix and can ensure that the atomized matrix can be smoothly discharged during subsequent use.

[0097] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
