[0033] It should also be understood that the terminology used in this specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in this specification of the present invention and the appended claims, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0034] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0035] A specific embodiment of the present invention discloses an atomizer. Please refer to Figures 1-4 , the atomizer includes a mouthpiece 1, an oil reservoir 15, and a base 10; a child lock structure 13 is provided between the base 10 and the oil reservoir 15. The child lock structure 13 includes an oil filling member 12 that can move up and down, a rotating plate 131 movably connected to the oil filling member 12, and a fixing plate 132. In this embodiment, the oil filling member 12 is tubular. An installation hole is formed on the base 10. The oil filling member 12 is placed in the installation hole and can move relative to the installation hole. An oil filling port 122 is provided at one end of the oil filling member 12 away from the oil reservoir 15, and an oil outlet 121 is provided at one end close to the oil reservoir 15. An exhaust hole plug 11 for sealing the exhaust hole 101 is provided at the bottom of the oil filling member 12. The base 10 is provided with an installation groove. The fixing plate 132 is fixed in the installation groove. The rotating plate 131 is rotatably connected to the fixing plate 132 and is kept in linkage with the oil filling member 12.

[0036] During oil filling, the e-liquid bottle S is pressed down to push the oil filling member 12 to move towards the mouthpiece 1, so that the oil outlet 121 is communicated with the oil reservoir 15 (after the oil outlet 121 is communicated with the oil reservoir 15, the oil in the e-liquid bottle S can smoothly enter the oil reservoir 15 to complete the oil filling process). When the oil filling member 12 moves towards the mouthpiece 1, the exhaust hole plug 11 will move away from the exhaust hole 101, and will simultaneously drive the rotating plate 131 to rotate in the opposite direction of the moving direction of the oil filling member 12. When the oil filling is completed, the e-liquid bottle S leaves the oil filling member 12, and the rotating plate 131 is pressed to rotate to the initial position. During the rotation of the rotating plate 131, the oil filling member 12 will be synchronously driven to move away from the mouthpiece 1 to return to the initial position, and the exhaust hole plug 11 will re-seal the exhaust hole 101.

[0037] Since the oil outlet 121 of the oil filling member 12 is blocked and closed by the hole wall of the mounting hole when in the initial position, the oil outlet 121 is not communicated with the oil tank 15, and oil leakage will not occur.

[0038] Specifically, a retaining edge is provided at the outer end of the oil filling member 12, and the front end of the fixing plate 132 extends into the moving range of the retaining edge; in the initial state, the rotating plate 131 is flush with the bottom surface of the base 10. When the oil filling member 12 moves towards the suction nozzle 1, the retaining edge of the oil filling member 12 presses down the rotating plate 131, causing the rear end of the rotating plate 131 to tilt upwards and protrude from the bottom surface of the base 10. By pressing the part of the rotating plate 131 that protrudes from the bottom surface of the base 10, the oil filling member 12 can be made to return to the initial position in the direction away from the suction nozzle 1. When the oil filling member 12 retracts, it can synchronously drive the exhaust hole plug 11 back to the initial position. In addition, the retaining edge also serves to limit the movement of the oil filling member 12 to prevent the oil filling member 12 from moving too far towards the oil tank 15.

[0039] It should be noted that for the convenience of oil filling, the atomizer is turned upside down, that is, the base 10 faces upwards. Figure 6 This is the state where the atomizer is turned upside down. In this state, the e-liquid bottle S can fill the oil tank 15 with oil. Figure 7 The state of is the state during oil filling. As can be seen from the figure, compared with Figure 6 , the position of the oil filling member 12 has moved downwards. After moving downwards, the oil outlet 121 on the oil filling member 12 just communicates with the oil tank 15, and the exhaust hole plug 11 moves away from the position of the exhaust hole 101. At this time, oil filling into the oil tank 15 and opening the exhaust channel for exhaust are synchronously achieved. Figure 7 The water droplet shape in represents the shape of the oil dropped into the oil tank 15. Figure 7 and Figure 8 The arrow shape in represents the exhaust path. Figure 9 and Figure 10 The state of is the state where the e-liquid bottle S leaves the oil filling member 12 after oil filling is completed. In this state, the oil outlet 121 and the exhaust hole 101 are not closed. Figure 11 The state of is the state diagram where the oil filling member 12 and the child lock structure 13 return to the initial position after oil filling is completed. In this state, the oil outlet 121 is blocked and closed by the hole wall of the mounting hole, and the exhaust hole 101 is blocked and closed by the exhaust hole plug 11.

[0040] In this embodiment, the rotating plate 131 and the oil filling member 12 are of a split structure. Of course, in other embodiments, the rotating plate 131 and the oil filling member 12 can be of an integral structure.

[0041] Further, please refer to Figure 3 、 4, a sealing seat 9 is further provided between the base 10 and the oil tank 15. A guiding hole for guiding the oil filling member 12 is provided at the corresponding position of the sealing seat 9 and the oil filling member 12. The exhaust hole 101 is provided on the sealing seat 9, and both the guiding hole and the exhaust hole 101 penetrate through the sealing seat 9. The base 10 is provided with an air outlet communicating with the outside, and an exhaust passage is formed between the exhaust hole 101 and the air outlet. Figure 7 and Figure 8 The path indicated by the arrow in Figure 8 is the path of the exhaust passage. The function of the sealing seat 9 is to seal the oil tank 15 to prevent the oil tank 15 from leaking oil. In addition, the sealing seat 9 also has the functions of waterproofing and moisture-proofing. Preferably, the sealing seat 9 is made of silica gel material.

[0042] In some embodiments, such as in this embodiment, the exhaust hole plug 11 includes a fixing portion, a plugging portion and a connecting portion. The connecting portion connects the fixing portion and the plugging portion into one body. The fixing portion is fixedly connected to the port portion at the inner end of the oil filling member 12, and the plugging portion is sealingly connected to the inner end orifice of the exhaust hole 101. In order to achieve better airtightness, the exhaust hole plug 11 is made of silica gel material. In this embodiment, the exhaust hole plug 11 and the oil filling member 12 are of a split structure. In other embodiments, the exhaust hole plug 11 can be of an integral structure with the oil filling. It should be noted that the exhaust hole plug 11 not only has the function of sealing the exhaust hole 101, but also has the function of restricting the moving distance of the oil filling assembly away from the oil tank 15.

[0043] Further, please refer to Figure 3 , the atomizer further includes a bracket 8, a heating wire 7, an atomization tube 4 and an airway tube 3; the lower end of the bracket 8 passes through the sealing seat 9 and is fixed on the base 10. An electrode 14 is provided on the base 10. The heating wire 7 is installed on the bracket 8 and is electrically connected to the electrode 14. The head of the heating wire 7 is wrapped with an inner cotton 6. The atomization tube 4 is sleeved on the bracket 8. An outer cotton 5 is provided between the atomization tube 4 and the bracket 8. The airway tube 3 is fixed above the atomization tube 4, and an O-ring 2 is sleeved on the upper end of the airway tube 3.

[0044] The specific embodiment of the present invention also discloses an aerosol generating device, which includes a main body and the above-mentioned atomizer; the atomizer is installed on the main body. The aerosol generating device includes the above-mentioned atomizer. Since the aerosol generating device adopts the above-mentioned atomizer, the technical effects that the above-mentioned atomizer can achieve, the aerosol generating device of the specific embodiment of the present invention also has the same technical effects.

[0045] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention.
