Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomization device and atomization equipment. 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] However, in the existing technology, due to unreasonable design of the oil storage chamber, either the e-liquid in the oil storage chamber cannot flow smoothly and be absorbed into the atomizer core, that is, the oil intake is not smooth, or the e-liquid in the oil storage chamber flows into the atomizer core excessively and seeps out from the atomizer core, resulting in oil leakage. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizing device that solves the problems of poor oil intake and easy oil leakage in existing atomizing devices.

[0005] To achieve the above objectives, the atomizing device proposed in this utility model includes:

The top arm pushes the elastic sealing plug towards the oil supply cavity to open the lower oil hole, which communicates with the oil storage cavity.

[0008] The atomizing tube has an oil inlet hole on its wall that connects the atomizing core and the oil storage chamber. The sealing assembly has multiple spaced filling protrusions that protrude downwards. The multiple filling protrusions are arranged around the circumference of the atomizing tube and are arranged to avoid the oil inlet hole. There is an oil passage gap between the filling protrusions and the wall and top arm of the atomizing tube.

[0009] 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.

[0010] 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 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.

[0011] Optionally, the lower side of the connector has a downward-facing mounting groove, the bottom of the mounting groove is provided with the filling protrusion, the oil drain hole and the through hole extend to penetrate the bottom of the mounting groove, the upper part of the mounting base is inserted into the mounting groove, the groove opening wall of the receiving groove is adjacent to or in contact with the bottom wall of the mounting groove, the inner wall of the through hole has a limiting step, the upper part of the atomizing tube is inserted into the through hole, and the top wall of the atomizing tube abuts against the step surface of the limiting step.

[0012] Optionally, a limiting groove is formed on the outer wall of the mounting base, and a sealing ring is installed in the limiting groove, the sealing ring abutting against the side wall of the mounting groove.

[0013] 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.

[0014] Optionally, the upper side of the connector is formed with a limiting groove, and the lower side of the seal is provided with a limiting protrusion, the limiting protrusion being inserted into the limiting groove; and / or, the upper side of the connector is provided with a limiting post, the seal is provided with a limiting hole, and the limiting post is inserted into the limiting hole.

[0015] Optionally, the top arm includes a connecting portion and a lifting portion in sequence in the extending direction, the width of the connecting portion is greater than the width of the lifting portion, and the chamfer formed at the connection between the connecting portion and the lifting portion is a convex arc chamfer.

[0016] 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.

[0017] Optionally, the oil inlet is located at the bottom of the oil storage chamber, or the oil inlet is adjacent to the bottom of the oil storage chamber.

[0018] This utility model also proposes an atomizing device, including a power supply device and the aforementioned atomizing device, wherein the power supply device is used to provide electrical energy to the atomizing device.

[0019] The technical solution of this utility model reduces the volume of the oil storage cavity by setting filling protrusions to fill the oil storage cavity, thus avoiding large-area cavities in the oil storage cavity and preventing negative pressure from being generated in the oil storage cavity. This ensures that the e-liquid in the oil storage cavity can flow smoothly through the oil inlet and be absorbed into the atomizer core, that is, ensure smooth oil intake. In addition, the smaller volume of the oil storage cavity reduces the gravity of the e-liquid in the oil storage cavity, thereby preventing the e-liquid from flowing excessively into the atomizer core due to gravity and seeping out from the atomizer core, thus preventing oil leakage.

[0040] The following will mainly describe the specific structure of the atomizing device.

[0041] Reference Figures 1 to 8 In this embodiment of the utility model, the atomizing device includes:

[0042] The oil storage component 10 includes a tank body 100 and a sealing assembly 200 installed on the lower side of the tank body 100. The upper side of the sealing assembly 200 and the tank body 100 enclose an oil supply chamber 11. The sealing assembly 200 is provided with an oil drain hole 221 communicating with the oil supply chamber 11, and an elastic sealing plug 211 is provided at the oil drain hole 221.

[0043] The atomizing assembly 20 includes a mounting base 300, an atomizing tube 400, and an atomizing core 500. The atomizing core 500 is installed inside the atomizing tube 400. A receiving groove 310 is formed on the upper side of the mounting base 300. A mounting hole 311 is provided at the bottom of the receiving groove 310. The bottom of the atomizing tube 400 is installed in the mounting hole 311. An upwardly protruding top arm 312 is provided on the side wall or opening wall of the receiving groove 310. The mounting base 300 is detachably mounted to the atomizing core 500. The sealing component 200 is used to give the atomizing device a disassembled state and an assembled state. In the disassembled state, the elastic sealing plug 211 blocks the lower oil hole 221. In the assembled state, the mounting base 300, the atomizing tube 400, the chamber 100, and the sealing component 200 enclose an oil storage chamber 21. The top arm 312 pushes the elastic sealing plug 211 into the oil supply chamber 11 to open the lower oil hole 221, and the lower oil hole 221 communicates with the oil storage chamber 21.

[0044] The atomizing tube 400 has an oil inlet 410 on its wall that connects the atomizing core 500 and the oil storage chamber 21. The sealing assembly 200 has a plurality of spaced filling protrusions 223 protruding downwards. The plurality of filling protrusions 223 are arranged around the circumference of the atomizing tube 400 and are arranged to avoid the oil inlet 410. There is an oil passage gap between the filling protrusions 223 and the wall of the atomizing tube 400 and the top arm 312.

[0045] Specifically, in this embodiment, the oil storage component 10 and the atomizing component 20 are separated before formal use. At this time, the atomizing core 500 does not adsorb e-liquid, and the e-liquid is stored in the oil supply chamber 11. The elastic sealing plug 211 blocks the lower oil hole 221 to ensure the sealing of the oil supply chamber 11, so that the e-liquid is located in the sealed oil supply chamber 11 and is not easily oxidized by air.

[0046] When the user needs to use the atomizing device, the atomizing component 20 is installed on the sealing component 200. After installation, an oil storage chamber 21 is formed between the atomizing component 20 and the oil storage component 10. At this time, the top arm 312 of the mounting base 300 lifts the elastic sealing plug 211, so that the oil outlet 221 is opened. In this way, the e-liquid in the oil supply chamber 11 can flow into the oil storage chamber 21 through the oil outlet 221, and then flow and be absorbed into the atomizing core 500 through the oil inlet 410 of the atomizing tube 400, so as to be atomized into a mist for the user to inhale. Because the sealing assembly 200 has multiple downward-protruding filling protrusions 223, and the filling protrusions 223 are arranged to avoid the oil inlet hole 410, and there are oil passage gaps between them and the atomizing tube 400 and the top arm 312, the oil storage chamber 21 is partially filled without affecting the oil inlet. In this way, the volume of the oil storage chamber 21 is reduced, avoiding the formation of large-area cavities in the oil storage chamber 21, thereby avoiding the generation of negative pressure in the oil storage chamber 21. This ensures that the e-liquid in the oil storage chamber 21 can flow smoothly through the oil inlet hole 410 and be absorbed into the atomizing core 500, thus ensuring smooth oil inlet. In addition, the reduced volume of the oil storage chamber 21 results in a smaller weight of e-liquid in the oil storage chamber 21, thereby preventing the e-liquid from flowing excessively into the atomizing core 500 due to gravity and seeping out from the atomizing core 500, thus preventing oil leakage.

[0047] The technical solution of this utility model reduces the volume of the oil storage cavity 21 by setting the filling protrusion 223 to fill the oil storage cavity 21, thereby avoiding large-area cavities in the oil storage cavity 21 and preventing negative pressure from being generated in the oil storage cavity 21. This ensures that the e-liquid in the oil storage cavity 21 can flow smoothly through the oil inlet 410 and be absorbed into the atomizing core 500, thus ensuring smooth oil intake. In addition, the smaller volume of the oil storage cavity 21 reduces the gravity of the e-liquid in the oil storage cavity 21, thereby preventing the e-liquid from flowing excessively into the atomizing core 500 due to gravity and seeping out from the atomizing core 500, thus preventing oil leakage.

[0048] 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 220 and a seal 210. The lower end of the connector 220 is snap-fitted to the inner wall of the chamber 100. The connector 220 has a through hole 224, an oil drain hole 221, and a filling protrusion 223. The seal 210 covers the upper end of the connector 220, and the outer peripheral wall of the seal 210 is flush with the chamber. The inner peripheral wall of the body 100 abuts against the seal 210. The top wall of the seal 210 is provided with the elastic sealing plug 211 and the oil passage 212 connecting the oil supply chamber 11 and the lower oil hole 221. The top wall of the seal 210 forms a downwardly extending insertion protrusion 213, which passes through the through hole 224 and is partially inserted into the atomizing tube 400. The seal 210 is provided with a sealing hole 214, which extends from the top wall of the seal 210 through the insertion protrusion 213. The lower end of the mist column 120 is inserted into the sealing hole 214, so that the mist outlet channel 121 communicates with the interior of the atomizing tube 400. In this way, the aerosol generated by the atomizing core 500 can flow out from the mouthpiece 110 through the mist outlet channel 121. The connector 220 is used to connect with the tank body 100, and the seal 210 has the effect of sealing the oil supply chamber 11, ensuring the sealing of the oil supply chamber 11 and preventing oil leakage.

[0049] In some embodiments, a downward-facing mounting groove 226 is formed on the lower side of the connector 220, the bottom of the mounting groove 226 is provided with the filling protrusion 223, the oil drain hole 221 and the through hole 224 extend to penetrate the bottom of the mounting groove 226, the upper part of the mounting base 300 is inserted into the mounting groove 226, the groove wall of the receiving groove 310 is adjacent to or in contact with the bottom wall of the mounting groove 226, a limiting step 225 is formed on the inner wall of the through hole 224, the upper part of the atomizing tube 400 is inserted into the through hole 224, and the top wall of the atomizing tube 400 abuts against the step surface of the limiting step 225. Because the groove wall of the receiving groove 310 is close to or in contact with the bottom wall of the mounting groove 226, the space enclosed between the groove wall of the receiving groove 310 and the groove wall of the mounting groove 226 is minimized, thus reducing the volume of the oil storage chamber 21. This avoids large-area cavities in the oil storage chamber 21, preventing negative pressure from forming and ensuring that the e-liquid in the oil storage chamber 21 can flow smoothly through the oil inlet 410 and be absorbed into the atomizing core 500, ensuring smooth oil intake. In addition, the smaller volume of the oil storage chamber 21 results in less gravity for the e-liquid within it, preventing excessive flow of e-liquid into the atomizing core 500 due to gravity and thus preventing leakage. The top wall of the atomizing tube 400 abuts against the step surface of the limiting step 225, which helps improve the installation stability of the atomizing tube 400, thereby improving the stability and reliability of the internal structure of the atomizing device.

[0050] In some embodiments, a limiting groove is formed on the outer wall of the mounting base 300, and a sealing ring 320 is installed in the limiting groove. The sealing ring 320 abuts against the side wall of the mounting groove 226. The sealing ring 320 improves the sealing performance of the oil storage chamber 21, thereby effectively preventing oil leakage.

[0051] In some embodiments, the sealing hole 214 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 215 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 215. In this way, the sealing member 210 will not move upward, and when the elastic sealing plug 211 is pushed up, it will not cause the sealing member 210 to move upward, ensuring that the sealing member 210 can stably and reliably perform its sealing function.

[0052] In some embodiments, a limiting groove 227 is formed on the upper side of the connector 220, and a limiting protrusion 216 protrudes from the lower side of the seal 210, the limiting protrusion 216 being inserted into the limiting groove 227. This improves the stability of the seal 210 installed on the connector 220. There are many other ways to improve the stability of the seal 210 installation; for example, in other embodiments, a limiting post 228 protrudes from the upper side of the connector 220, and the seal 210 has a limiting hole 217, the limiting post 228 being inserted into the limiting hole 217.

[0053] In some embodiments, the top arm 312 sequentially includes a connecting portion 313 and a lifting portion 314 in the extending direction. The width of the connecting portion 313 is greater than the width of the lifting portion 314, and the chamfer formed at the connection between the connecting portion 313 and the lifting portion 314 is a convex arc-shaped chamfer. It is understood that the larger width of the connecting portion 313 can improve the strength of the top arm 312, thereby improving its reliability. The smaller width of the lifting portion 314 can prevent the top arm 312 from clogging the oil outlet 221, ensuring smooth oil supply. The convex arc-shaped chamfer formed at the connection between the connecting portion 313 and the lifting portion 314 allows the e-liquid to flow down along the convex arc-shaped chamfer, preventing e-liquid from stagnating at the connection and ensuring smooth oil flow.

[0054] In some embodiments, a guide slope 222 is formed on the wall surface of the lower oil hole 221 near the oil supply chamber 11. The guide slope 222 is used to guide the elastic sealing plug 211 into the lower oil hole 221. The guide slope 222 makes it easier for the operator to insert the elastic sealing plug 211 into the lower oil hole 221 to seal the lower oil hole 221 during the production process, thereby improving production efficiency.

[0055] In some embodiments, the oil inlet 410 is located at the bottom of the oil storage chamber 21, or the oil inlet 410 is adjacent to the bottom of the oil storage chamber 21. This allows most of the e-liquid in the oil storage chamber 21 to flow through the oil inlet 410 and be absorbed into the atomizer core 500, reducing the amount of e-liquid retained in the oil storage chamber 21 and minimizing e-liquid waste.

[0056] This utility model also proposes an atomizing device, which includes a power supply device and an atomizing device. The power supply device is used to provide electrical energy to the atomizing device. The specific structure of the 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 elaborated here.
