Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generating devices, and particularly to an atomizer and an aerosol generating device. Background Art

[0002] With the development of e-cigarette technology and the popularization of e-cigarettes, the market demand has been continuously increasing, and e-cigarettes have been widely recognized.

[0003] Currently, an atomizer core assembly is provided inside the atomizer of market e-cigarettes. However, due to the lifespan issue of the atomizer core assembly, after being recycled many times, these atomizer core assemblies need to be replaced, otherwise there will be impure taste or harmful substances. When a user needs to replace the atomizer core assembly in the atomizer, one way is to rotate and open the connection structure to take out the atomizer core assembly, and the other is to press the base to expose the atomizer core assembly and then directly pull it out. However, such disassembly methods are simple and easy for children to operate, resulting in a high probability that children may open the atomizer, thus coming into contact with the aerosol-forming substrate therein, and even causing the situation of accidental ingestion. Summary of the Invention

[0004] The purpose of the present invention is to provide an atomizer and an aerosol generating device with a structurally safe disassembly method.

[0005] The present invention discloses an atomizer core, including a housing provided with a through air outlet and an air inlet; an airway tube inserted on the housing and movably connected to the air outlet; an atomizer core disposed inside the housing, with the end of the atomizer core away from the air inlet abutting against the airway tube; a base connected to the housing and disposed at the air inlet; wherein, in the natural state, the base is flush with the end of the atomizer core; when the airway tube moves towards the air inlet, the atomizer core is exposed outside the base.

[0006] Optionally, the atomizer further includes an elastic component disposed between the airway tube and the atomizer core for providing an elastic restoring force for the airway tube.

When an external force moves the airway tube from a first position to a second position, the elastic component is stretched, and the atomizer core moves along the air inlet so that the atomizer core protrudes from the air inlet to form a stepped structure with the base. When the external force disappears, the airway tube returns from the second position to the first position under the action of the elastic restoring force of the elastic component.

[0008] Optionally, the elastic component includes an elastic member and a sliding ring. The sliding ring is sleeved on the outer wall of the airway tube. One end of the elastic member is connected to the oil storage chamber, and the other end is connected to the sliding ring.

[0009] Optionally, the housing further includes a top cover ring and a bottom cover ring. The top cover ring is connected to the oil storage chamber and is disposed between the air outlet and the airway tube. The top cover ring is connected to the bottom cover ring. The airway tube is movably connected to the top cover ring and the bottom cover ring. A cavity is formed between the outer wall of the airway tube and the top cover ring. The elastic member and the sliding ring are disposed in the cavity.

[0010] Optionally, the elastic member is connected to the top cover ring. The sliding ring slides in the cavity towards the air inlet direction and drives the elastic member to stretch. The sliding ring abuts against the bottom cover ring. The end of the atomization core protrudes from the base.

[0011] Optionally, a resisting portion is provided on the outer wall of the airway tube.

[0015] In the atomizer according to the embodiment of the present invention, through the transmission connection among the elastic component, the airway tube and the atomization core, in the natural state, the atomizer is in the housing, and the end of the atomization core is flush with the base. The atomization core cannot be directly taken out from the base. When replacing or taking out the atomization core, only need to press the airway tube. After pressing, the airway tube will push the atomization core out of the base to form a step, then can pinch both sides of the atomization core, and then take out the atomization core. This operation is relatively complicated for children, which can reduce or avoid the possibility that children take out the atomization core, and further reduce or avoid children contacting or ingesting the aerosol generating matrix therein.

Detailed Embodiments

[0024] It should be understood that the terms, specific structures and functional details used here are only for describing specific embodiments, which are representative, but the present invention can be specifically implemented in many alternative forms and should not be construed as being limited only to the embodiments described herein.

[0025] The present invention will be further described below with reference to the drawings and optional embodiments.

[0026] As Figures 1 to 6As shown in the figure, an embodiment of the present invention discloses an atomizer, which includes a housing 100, an airway tube 200, an atomization core 400, and a base 180. A through air outlet 110 and an air inlet 120 are provided on the housing 100; the airway tube 200 is inserted into the housing 100 and is movably connected to the air outlet 110; the atomization core 400 is arranged inside the housing 100, and the end of the atomization core 400 away from the air inlet 120 abuts against the airway tube 200; the base 180 is connected to the housing 100 and is arranged at the air inlet 120. Among them, in the natural state, the base 180 is flush with the end of the atomization core; when the airway tube 200 moves towards the air inlet 120, the atomization core 200 is exposed outside the base 180.

[0027] In the atomizer according to the embodiment of the present invention, through the transmission connection of the elastic component, the airway tube and the atomization core, in the natural state, the atomizer is inside the housing, and the end of the atomization core is flush with the base. The core cannot be directly taken out from the base. When replacing or taking out the atomization core, only need to press the airway tube. After pressing, the airway tube will push the atomization core out of the base to form a step, so that the two sides of the atomization core can be pinched, and then the atomization core can be taken out. This operation is relatively complicated for children, which can reduce or avoid the possibility that children take out the atomization core, and then reduce or avoid children contacting or ingesting the aerosol generation matrix therein.

[0028] Furthermore, the atomizer further includes an elastic component 300, which is arranged between the airway tube 200 and the atomization core 400 and is used to provide the elastic restoring force of the airway tube 200; after the airway tube 200 pushes out the atomization core 400, it provides the elastic restoring force of the airway tube 200, so that the airway tube 200 can reset after moving at the air outlet 120 without affecting inhalation.

[0029] Furthermore, as Figure 3 shown, the housing includes an oil storage chamber 150, the air outlet 110 is arranged on the oil storage chamber 150, one end of the airway tube 200 away from the air inlet 120 protrudes from the oil storage chamber 150, the air inlet 120 is arranged on the base 180, one end of the atomization core 400 away from the air inlet 120 is placed inside the oil storage chamber 150 and abuts against the airway tube 200, and the other end is placed inside the air inlet 120 and is movably connected to the air inlet 120. When an external force causes the airway tube 200 to move from the first position to the second position, the elastic component 300 is stretched, and the atomization core 400 moves along the air inlet 120, so that the atomization core 400 protrudes from the air inlet 120 to form a stepped structure with the base 180. When the external force disappears, the airway tube 200 returns from the second position to the first position under the action of the elastic restoring force of the elastic component 300.

[0030] As Figure 3 shown, in the initial state, the atomization core 400 is installed at the air inlet 120 and is inside the housing 100. The housing 100 is flush with the end of the atomization core 400. The atomization core 400 is communicated with the airway tube 200, so that the aerosol generated by the atomization core 400 is output from the airway tube 200. The atomization core 400 cannot be directly taken out from the air outlet 110 of the housing 100. When the atomization core 400 needs to be removed, as Figure 5 shown, press the airway tube 200 to move the airway tube 200 downward relative to the air outlet 110. At this time, the elastic component 300 is stretched to generate an elastic force. The airway tube 200 presses the atomization core 400 to push the atomization core 400 out of the housing 100 from the air inlet 120 to form a step, and then the atomization core 400 can be easily pulled out. After pulling out, release the airway tube 200, and the airway tube 200 automatically rebounds and resets under the elastic force of the elastic component 300. Subsequently, insert a new atomization core 400 into the air inlet 120, so that the end of the newly replaced atomization core 400 is flush with the housing 100 again and cannot be directly pulled out from the outside.

[0031] Specifically, as Figures 1 to 2 shown, the elastic component 300 includes an elastic member 310 and a sliding ring 320. The sliding ring 320 is sleeved on the outer wall of the airway tube 200. One end of the elastic member 310 is connected to the oil storage chamber 150, and the other end is connected to the sliding ring 320; the sliding ring 320 is sleeved on the outer wall of the airway tube 200 and can slide synchronously with the airway tube 200 along the axial direction of the air outlet 110. One end of the elastic member 310 is connected to the inner wall of the housing 100, and the other end is connected to the sliding ring 320. In this embodiment, the elastic member 310 is a spring. In the initial state, the sliding ring 320 is at a high position and the spring is in a natural state. When the airway tube 200 is pressed downward, the airway tube 200 moves downward along the air outlet 110, driving the sliding ring 320 to move from a high position to a low position. The end of the airway tube 200 pushes the atomization core 400 out of the housing 100. At this time, the spring is in a stretched state, providing an elastic restoring force. Release the pressure on the airway tube 200, and the elastic member 310 rebounds to spring the airway tube 200 back to its original position.

[0032] More specifically, the housing 100 further includes a top cover ring 130 and a bottom cover ring 140. The top cover ring 130 is connected to the oil storage chamber 150 and is disposed between the air outlet 110 and the airway tube 200. The top cover ring 130 is connected to the bottom cover ring 140. The airway tube 200 is movably connected to the top cover ring 130 and the bottom cover ring 140. A cavity 131 is formed between the outer wall of the airway tube 200 and the top cover ring 130. The elastic member 310 and the sliding ring 320 are disposed in the cavity 131. The top cover ring 130 and the bottom cover ring 140 form the air outlet 110, enabling the airway tube 200 to slide within the air outlet 110 and connecting the airway tube 200 to the atomization core 400. The sealing structure formed by the top cover ring 130 and the bottom cover ring 140 isolates the e-liquid in the oil storage chamber 150, preventing the e-liquid from directly entering the airway tube 200 and the cavity 131 and contaminating the elastic member 310 and the sliding ring 320 in the cavity 131.

[0033] In this embodiment, the top cover ring 130 is directly inserted into the oil storage chamber 150, with a part exposed outside the oil storage chamber 150. A limiting portion (not shown) is provided on the top cover ring 130 to limit the position after the top cover ring 130 is inserted. Another part is disposed inside the oil storage chamber 150. The bottom cover ring 140 is connected to the bottom of the top cover ring 130 to form a hollow structure. The airway tube 200 is inserted between the two. The cavity 131 formed between the airway tube 200 and the top cover ring 130 is used to accommodate the sliding ring 320 and the elastic member 310, providing a sliding sealing space.

[0034] Further, the elastic member 310 is connected to the top cover ring 130. The sliding ring 320 slides in the cavity 131 towards the air inlet 120 direction and drives the elastic member 310 to stretch. The sliding ring 320 abuts against the bottom cover ring 140. The end of the atomization core 400 protrudes from the base 180, restricting the sliding stroke of the sliding ring 320 and thus limiting the sliding stroke of the airway tube 200.

[0035] In this embodiment, the elastic member 310 is fixed to the top cover ring 130. One end of the sliding ring 320 is connected to the elastic member 310. The sliding ring 320 slides in the cavity 131. When the atomization core 400 and the housing 100 form a stepped surface and have reached the position where it can be taken out, the sliding ring 320 slides to abut against the bottom cover ring 140, that is, it cannot slide further, limiting the downward pressing distance stroke of the airway tube 200 and also limiting the stretching stroke of the elastic member 310, avoiding excessive stretching and causing elastic fatigue damage.

[0036] Even further, as Figures 3 to 6As shown, a resisting portion 210 is provided on the outer wall of the airway tube 200. The end of the airway tube 200 away from the air outlet 110 extends out of the bottom cover ring 140 and is inserted into the atomization core 400. In the natural state, the resisting portion 210 abuts against the atomization core 400 and the bottom cover ring 140. Through the initial elastic force of the elastic member 310 and the abutting and limiting of the resisting portion 210, the airway tube 200 is positioned so that the airway tube 200 will not slide by itself in the natural state. The resisting portion 210 also has the function of conducting force on the atomization core 400 to push out the atomization core 400, and at the same time, it also has a blocking effect on the air inlet 120 to further prevent e-liquid from entering.

[0037] In this embodiment, the resisting portion 210 is in the shape of a sheet and surrounds the outer wall of the airway tube 200. In the initial state, the elastic member 310 has a pre-elastic force, which stretches the airway tube 200 towards the air outlet 110. At this time, the resisting portion 210 abuts against the bottom cover ring 140 to position the airway tube 200. The resisting portion 210 has a continuous acting force on the bottom cover ring 140 to prevent the airway tube 200 from sliding by itself. At the same time, the other side of the resisting portion 210 abuts against the atomization core 400. When the airway tube 200 is pressed down, the atomization core 400 is pushed out through the conduction of force by the resisting portion 210, which is labor-saving and has a good force-receiving effect.

[0038] As Figure 2 and Figure 3 shown, a first sealing ring 160 is provided on the inner walls of the top cover ring 130 and the bottom cover ring 140 to seal the air outlet 110 to prevent e-liquid from entering and is also beneficial to the sliding of the airway tube 200. In this embodiment, the first sealing ring 160 is placed in the installation groove (not shown) on the inner walls of the top cover ring 130 and the bottom cover ring 140, and its surface slightly protrudes. When the airway tube 200 is inserted into the air outlet 110, it is squeezed with the first sealing ring 160 to seal both the upper and lower ends. The first sealing ring 160 can be made of silicone or rubber material, and preferably silicone material.

[0039] As Figure 4 shown, the atomizer further includes a mouthpiece 500. The mouthpiece 500 is detachably connected to the top cover ring 130 and covers the airway tube 200. The mouthpiece 500 is communicated with the airway tube 200 for the user to inhale the generated aerosol. On the other hand, when in use, the mouthpiece 500 covers the airway tube 200, so it cannot generate a downward pressure on the airway tube 200, thus not pushing out the atomization core 400. When the atomization core 400 needs to be replaced, the mouthpiece 500 needs to be removed first before the airway tube 200 can be pressed down, which further improves the safety and prevents misoperation.

[0040] In addition, a second sealing ring 170 is provided on the outer wall of the top cover ring 130. The second sealing ring 170 is arranged in a mounting groove (not shown) on the outer wall of the top cover ring 130. After the nozzle 500 is covered with the top cover ring 130, the nozzle 500 and the second sealing ring 170 are mutually extruded to provide a pre-tightening force, so that the nozzle 500 is firmly installed and has a good sealing effect.

[0041] As Figure 2 shown, a magnet seat 190 is provided in the base 180 of the housing 100. The magnet seat 190 is connected to the oil storage chamber 150. The base 180 covers the magnet seat 190. A magnet 191 is provided on the magnet seat 190. When the base 180 is plugged into an external host, it is adsorbed and fixed by the adsorption force of the magnet 191.

[0042] As another embodiment of the present invention, an aerosol generating device is disclosed, which includes a main body and the atomization core 400 described in the above embodiment. The atomization core 400 is installed on the main body.

[0043] Specifically, a power supply and a power supply electrode electrically connected to the power supply are provided on the main body. When the atomizer is installed on the main body, the electrode assembly is in contact with the power supply electrode to conduct electricity, so that the power supply supplies power to the atomization core 400 to make it heat up, heats the e-liquid, thereby generating aerosol, and discharges it to the nozzle 500 through the air duct for the user to inhale.

[0044] The above content is a further detailed description of the present invention in combination with specific optional embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
