Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomizing device and atomizing equipment with air exchange capability. Background Technology

[0002] Existing atomizing devices typically include an atomizing unit and a power supply unit that powers the atomizing unit. The atomizing unit internally comprises a supply chamber, a reservoir chamber, an atomizing chamber, and an atomizing coil located within the atomizing chamber. The supply chamber supplies e-liquid to the reservoir chamber, which is connected to the atomizing chamber. The atomizing coil absorbs the e-liquid from the reservoir chamber, and the atomizing chamber is connected to the outside. During use, the power supply unit powers the atomizing coil, causing the coil to convert the absorbed e-liquid into a vapor for the user to inhale.

[0003] During the process of supplying e-liquid from the supply chamber to the storage chamber, the injection of e-liquid compresses the space occupied by the gas in the storage chamber, causing the gas pressure in the storage chamber to increase. However, in the existing technology, the gas in the storage chamber only exchanges with the atomizing chamber through the inlet hole of the atomizing tube. The ventilation effect is poor, which can easily cause the e-liquid in the storage chamber to flow excessively into the atomizing coil and seep out from the atomizing coil, thus easily causing e-liquid leakage. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizing device with ventilation capability, which aims to solve the problem of poor ventilation effect of existing atomizing devices.

[0005] To achieve the above objectives, the present invention proposes an air-exchangeable atomizing device comprising: An oil storage device includes a tank body and a sealing assembly installed on the tank body. The sealing assembly and the tank body enclose an oil supply chamber. The sealing assembly is provided with an oil drain hole communicating with the oil supply chamber, and an elastic sealing plug is provided at the oil drain hole. The atomizing assembly includes a mounting component, an atomizing tube, an air exchange tube, and an atomizing core. The atomizing core is installed inside the atomizing tube. The air exchange tube and the atomizing tube are installed on the upper side of the mounting component. The mounting component is detachably installed on the lower side of the chamber, so that the air-exchangeable atomizing device has a disassembled state and an assembled state. In the disassembled state, the elastic sealing plug blocks the lower oil hole. In the assembled state, the mounting component, the atomizing tube, the inner wall of the chamber, and the sealing component enclose an oil storage chamber. The air exchange tube pushes the elastic sealing plug towards the oil supply chamber to open the lower oil hole, and the lower oil hole communicates with the oil supply chamber. The atomizing tube has an oil inlet hole in its wall that connects the oil storage chamber and the atomizing core; the ventilation tube has a ventilation channel that connects to the oil supply chamber, and the ventilation tube has a ventilation hole in its wall that connects the ventilation channel and the oil storage chamber.

[0006] Optionally, the vent is located above and close to the oil inlet.

[0007] Optionally, a suction nozzle is formed on the top of the chamber, and a mist column is formed in the chamber. The interior of the mist column is provided with a mist outlet channel that extends through both ends of the mist column, and the upper end of the mist outlet channel is connected to the suction nozzle. The sealing assembly includes a connector and a seal. The lower end of the connector is snapped into the inner wall of the chamber. The connector has a through hole and a lower oil hole. The seal covers the upper end of the connector. The outer peripheral wall of the seal abuts against the inner peripheral wall of the chamber. The top wall of the seal has an elastic sealing plug and an oil passage connecting the oil supply chamber and the lower oil hole. The top wall of the seal has a downwardly extending insertion protrusion that passes through the through hole and is partially inserted into the atomizing tube. The seal has a sealing hole that extends from the top wall of the seal through the insertion protrusion. The lower end of the mist column is inserted into the sealing hole so that the mist outlet channel communicates with the interior of the atomizing tube.

[0008] Optionally, the elastic sealing plug includes a connecting arm and a sealing plug. One end of the connecting arm is connected to the top wall of the sealing element and is located near the oil passage, and the other end is connected to the sealing plug. In the disassembled state, the sealing plug is inserted into the lower oil passage, and the connecting arm is bent into an "n" shape. In the assembled state, the connecting arm is vertical, and the sealing plug is located above the connecting arm and away from the lower oil passage.

[0009] Optionally, the side of the sealing plug opposite to the lower oil hole is configured as a concave arc shape to have a concave arc surface. In the assembled state, the concave arc surface of the air-exchangeable atomizing device is close to or fits against the outer peripheral wall of the mist column.

[0010] Optionally, the connecting arm is integrally formed with the sealing plug and the sealing element.

[0011] Optionally, the sealing hole includes a first hole segment and a second hole segment in sequence in the extending direction. The inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, so as to form a limiting step at the connection between the first hole segment and the second hole segment. The lower end wall of the mist column abuts against the step surface of the limiting step.

[0012] Optionally, the mounting assembly includes a base and a sealing sleeve. The lower end of the base is snapped into the inner wall of the chamber. The upper side of the base is provided with a mounting hole. The sealing sleeve covers the upper end of the base. The outer peripheral wall of the sealing sleeve abuts against the inner peripheral wall of the chamber. The top wall of the sealing sleeve is provided with a limiting hole corresponding to the position of the mounting hole. The ventilation pipe passes through the limiting hole and is inserted into the mounting hole.

[0013] Optionally, a guide slope is formed on the wall surface of the lower oil hole near the oil supply chamber, and the guide slope is used to guide the elastic sealing plug to be inserted into the lower oil hole.

[0014] This utility model also proposes an atomizing device, including a power supply device and the above-mentioned ventilable atomizing device, wherein the power supply device is used to provide electrical energy to the ventilable atomizing device.

[0015] The technical solution of this utility model, by setting up a ventilation pipe, can be used to open the elastic sealing plug to open the lower oil hole, realizing automatic oil supply as soon as the atomizing device is assembled. At the same time, when the air pressure in the oil storage chamber is too high and the e-liquid level in the oil supply chamber is lower than the ventilation pipe, it provides a ventilation path for the gas in the oil storage chamber. Under pressure, the gas in the oil storage chamber can flow sequentially through its ventilation hole and ventilation channel to the cavity of the oil supply chamber. Because the ventilation pipe is small in size, even if there is e-liquid in the ventilation channel, the amount of e-liquid is relatively small, and the resistance to gas flow is relatively small. Therefore, the gas can flow into the oil supply chamber relatively smoothly. Compared with the ventilation through the oil inlet hole of the atomizing tube and the atomizing chamber, the ventilation effect is better, thereby effectively avoiding the phenomenon of excessive e-liquid flowing into the atomizing core and then seeping out from the atomizing core, thus effectively preventing oil leakage.

[0022] The following will mainly describe the specific structure of the air-exchangeable atomizing device.

[0023] Reference Figures 1 to 6 In this embodiment of the invention, the ventilable atomizing device includes: An oil storage device includes a tank body 100 and a sealing assembly 200 installed on the tank body 100. The sealing assembly 200 and the tank body 100 enclose an oil supply chamber 101. The sealing assembly 200 is provided with an oil drain hole 211 communicating with the oil supply chamber 101, and an elastic sealing plug 230 is provided at the oil drain hole 211. The atomizing assembly includes an installation component, an atomizing tube 330, an air exchange tube 340, and an atomizing core 350. The atomizing core 350 is installed inside the atomizing tube 330. The air exchange tube 340 and the atomizing tube 330 are installed on the upper side of the installation component. The installation component is detachably installed on the lower side of the chamber 100, so that the air-exchangeable atomizing device has a disassembled state and an assembled state. In the disassembled state, the elastic sealing plug 230 blocks the lower oil hole 211. In the assembled state, the installation component, the atomizing tube 330, the inner wall of the chamber 100, and the sealing component 200 enclose an oil storage chamber 301. The air exchange tube 340 pushes the elastic sealing plug 230 toward the oil supply chamber 101 to open the lower oil hole 211. The lower oil hole 211 communicates with the oil supply chamber 101. The atomizing tube 330 has an oil inlet 331 on its wall that connects the oil storage chamber 301 and the atomizing core 350; the ventilation tube 340 has a ventilation channel 341 that connects to the oil supply chamber 101, and the ventilation tube 340 has a ventilation hole 342 on its wall that connects the ventilation channel 341 and the oil storage chamber 301.

[0024] Specifically, in this embodiment, the oil storage component and the atomizing component are separated before formal use. At this time, the atomizing core 350 does not adsorb e-liquid, and the e-liquid is stored in the oil supply chamber 101. The elastic sealing plug 230 seals the lower oil hole 211 to ensure the sealing of the oil supply chamber 101, so that the e-liquid is located in the sealed oil supply chamber 101 and is not easily oxidized by air.

[0025] When the user needs to use the atomizing device, the atomizing component is installed on the lower side of the chamber 100. After installation, the atomizing component and the oil storage component form an oil storage chamber 301. At this time, the air exchange pipe 340 pushes open the elastic sealing plug 230, so that the oil outlet 211 is opened. In this way, the e-liquid in the oil supply chamber 101 can flow into the oil supply chamber 101 through the oil outlet 211, and then flow and be absorbed into the atomizing core 350 through the oil inlet 331 of the atomizing tube 330, so as to be atomized into mist for the user to inhale. Because the ventilation pipe 340 is equipped with a ventilation channel 341 and a ventilation hole 342, when the air pressure in the oil storage chamber 301 is too high and the e-liquid level in the oil supply chamber 101 is lower than that in the ventilation pipe 340, the gas in the oil storage chamber 301 can flow into the cavity of the oil supply chamber 101 through the ventilation hole 342 and the ventilation channel 341 under pressure. It can be understood that because the ventilation pipe 340 is relatively small, even if there is e-liquid in the ventilation channel 341, the amount of e-liquid is relatively small, and the resistance to gas flow is relatively small. Therefore, the gas can flow into the oil supply chamber 101 relatively smoothly. Compared with exchanging air with the atomizing chamber through the oil inlet 331 of the atomizing pipe 330, the ventilation effect is better, thus effectively preventing the phenomenon of excessive e-liquid flowing into the atomizing core 350 and then seeping out from the atomizing core 350, effectively preventing oil leakage. In practical applications, the ventilation hole 342 is located above and close to the oil inlet 331. This allows the gas around the oil inlet 331 to quickly enter the vent 342 and be quickly discharged into the cavity of the oil supply chamber 101, preventing the gas around the oil inlet 331 from blocking the oil inlet 331 and ensuring smooth oil intake.

[0026] The technical solution of this utility model, by setting up a ventilation pipe 340, can both open the elastic sealing plug 230 to open the lower oil hole 211, thus achieving automatic oil supply after the atomizing device is assembled, and also provide a ventilation path for the gas in the oil storage chamber 301 when the air pressure in the oil storage chamber 301 is too high and the e-liquid level in the oil supply chamber 101 is lower than the ventilation pipe 340. This allows the gas in the oil storage chamber 301 to pass through its ventilation hole 342 and the ventilation port 340 under pressure. The gas flows into the cavity of the supply chamber 101 through the channel 341. Since the ventilation tube 340 is small in size, even if there is e-liquid in the ventilation channel 341, the amount of e-liquid is relatively small, and the resistance to gas flow is relatively small. Therefore, the gas can flow into the supply chamber 101 relatively smoothly. Compared with exchanging air with the atomizing chamber through the oil inlet 331 of the atomizing tube 330, the ventilation effect is better, thereby effectively avoiding the phenomenon of excessive e-liquid flowing into the atomizing core 350 and then seeping out from the atomizing core 350, thus effectively preventing oil leakage.

[0027] In some embodiments, a suction nozzle 110 is formed on the top of the chamber 100, and a mist column 120 is formed in the chamber 100. The mist column 120 has a mist outlet channel 121 extending through both ends, and the upper end of the mist outlet channel 121 communicates with the suction nozzle 110. The sealing assembly 200 includes a connector 210 and a seal 220. The lower end of the connector 210 is snap-fitted to the inner wall of the chamber 100. The connector 210 has a through hole 213 and an oil drain hole 211. The seal 220 covers the upper end of the connector 210, and the outer peripheral wall of the seal 220 is flush with the inner wall of the chamber 100. The sealing element 220 has a circumferential wall abutment. Its top wall is provided with an elastic sealing plug 230 and an oil passage 221 connecting the oil supply chamber 101 and the lower oil hole 211. The top wall of the sealing element 220 has a downwardly extending insertion protrusion 222, which passes through the through hole 213 and partially inserts into the atomizing tube 330. The sealing element 220 also has a sealing hole 223, which extends from the top wall of the sealing element 220 through the insertion protrusion 222. The lower end of the mist column 120 is inserted into the sealing hole 223, so that the mist outlet channel 121 communicates with the interior of the atomizing tube 330. Thus, the aerosol generated by the atomizing core 350 can flow out from the mouthpiece 110 through the mist outlet channel 121. The connector 210 is used to connect with the tank body 100, and the seal 220 has the effect of sealing the oil supply chamber 101, ensuring the sealing of the oil supply chamber 101 and preventing oil leakage.

[0028] The elastic sealing plug 230 includes a connecting arm 231 and a sealing plug 232. One end of the connecting arm 231 is connected to the top wall of the sealing member 220 and is located near the oil passage 221, and the other end is connected to the sealing plug 232. In the disassembled state, the sealing plug 232 is inserted into the lower oil passage 211, and the connecting arm 231 is bent into an "n" shape. In the assembled state, the connecting arm 231 is vertical, and the sealing plug 232 is located above the connecting arm 231 and away from the lower oil passage 211. That is, when the atomizing device is in the disassembled state, the connecting arm 231 is in an elastic deformation state. When the air exchange tube 340 pushes open the sealing plug 232, the sealing plug 232 is disengaged from the lower oil hole 211. The connecting arm 231 returns to its natural state and drives the sealing plug 232 to move above the connecting arm 231. This is to prevent the sealing plug 232 from obstructing the e-liquid from entering the lower oil hole 211 next to the oil inlet 331, ensuring that the e-liquid in the oil supply chamber 101 can smoothly and unobstructedly enter the oil inlet 331, thereby allowing the e-liquid to quickly reach the oil storage chamber 301 and improving the oil supply efficiency.

[0029] Furthermore, the sealing plug 232 is configured with a concave arc shape on the side opposite to the lower oil hole 211, forming a concave arc surface 233. In the assembled state, the concave arc surface 233 of the ventilable atomizing device is adjacent to or conforms to the outer peripheral wall of the mist column 120. This configuration of the sealing plug 232 allows the mist column 120 to limit its movement, preventing it from wobbling and ensuring the stability of the internal structure of the atomizing device.

[0030] In some embodiments, the connecting arm 231 is integrally formed with the sealing plug 232 and the sealing element 220. Since the lower end of the mist column 120 is inserted into the sealing hole 223, the mist column 120 can limit the sealing element 220. Since the connecting arm 231 is integrally formed with the sealing plug 232 and the sealing element 220, the connecting arm 231 and the sealing plug 232 are also limited by the mist column 120. Moreover, the integrally formed structure has higher strength and is not easy to break, ensuring that the elastic sealing plug 230 can function stably and reliably.

[0031] In some embodiments, the sealing hole 223 sequentially includes a first hole segment and a second hole segment in the extending direction. The inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, so as to form a limiting step 224 at the connection between the first hole segment and the second hole segment. The lower end wall of the mist column 120 abuts against the step surface of the limiting step 224. In this way, the sealing member 220 is not easily moved upward. When the sealing plug 232 is pushed up, it will not cause the sealing member 220 to move upward, ensuring that the sealing member 220 can stably and reliably perform its sealing function.

[0032] Regarding the composition of the installation assembly, in some embodiments, the installation assembly includes a base 310 and a sealing sleeve 320. The lower end of the base 310 is snap-fitted to the inner wall of the chamber 100, and the upper side of the base 310 is provided with an installation hole 311. The sealing sleeve 320 covers the upper end of the base 310, and the outer peripheral wall of the sealing sleeve 320 abuts against the inner peripheral wall of the chamber 100. The top wall of the sealing sleeve 320 is provided with a limiting hole 321 corresponding to the position of the installation hole 311. The ventilation pipe 340 passes through the limiting hole 321 and is inserted into the installation hole 311. That is, the base 310 is used to connect with the chamber 100, and the sealing sleeve 320 is used to seal the oil storage chamber 301 to ensure the airtightness of the oil storage chamber 301. The ventilation pipe 340 passes through the limiting hole 321 and is inserted into the mounting hole 311, so that the ventilation pipe 340 is simultaneously limited by the base 310 and the sealing sleeve 320, ensuring the installation stability of the ventilation pipe 340, thereby enabling it to perform its ventilation function stably and reliably.

[0033] In some embodiments, a guide slope 212 is formed on the wall surface of the lower oil hole 211 near the oil supply chamber 101. The guide slope 212 is used to guide the elastic sealing plug 230 into the lower oil hole 211. The guide slope 212 makes it easier for the operator to insert the elastic sealing plug 230 into the lower oil hole 211 to seal the lower oil hole 211 during the production process, thereby improving production efficiency.

[0034] This utility model also proposes an atomizing device, which includes a power supply device and an exchanging air atomizing device. The power supply device is used to provide electrical energy to the exchanging air atomizing device. The specific structure of the exchanging air atomizing device is as described in the above embodiments. Since this atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
