Description

[0002] Atomizing devices typically consist of an atomizing unit and a power supply unit that powers the atomizing unit. The atomizing unit usually contains an oil reservoir, an atomizing tube, and an atomizing coil housed within the atomizing tube. The atomizing tube has oil guide holes in its wall that communicate with the oil reservoir, allowing liquid in the reservoir to flow to the atomizing coil. During use, the power supply unit powers the atomizing coil, causing it to heat up and convert the adsorbed liquid into a mist. This mist then flows through the interior of the atomizing tube and the mist outlet channel for the user to inhale.
[0003] As people continue to inhale, the e-liquid in the reservoir gradually decreases, inevitably creating negative pressure within the reservoir. Consequently, the e-liquid in the reservoir cannot continue to flow to the atomizer coil, which can easily lead to the atomizer coil burning dry.
[0004] Therefore, it is necessary to design an atomizing device to overcome the above-mentioned defects. Utility Model Content

[0036] The following will mainly describe the specific structure of the atomizing device.
[0037] Reference Figures 1 to 7 In this embodiment of the invention, the atomizing device includes an oil supply bottle 200 and an oil storage tank 100. The oil storage tank 100 is detachably installed on the oil supply bottle 200 and forms a ventilation gap with it communicating with the outside. The oil storage tank 100 includes:
[0038] The chamber 110 has an air vent 113 with a diameter of 0.5mm-2mm on the upper side and is open on the lower side;
[0039] The lower sealing seat 120 is installed on the lower side of the chamber body 110;
[0040] The atomizing tube 130 is installed at its lower end on the sealing seat and at its upper end near the upper side of the chamber 110. The tube wall of the atomizing tube 130 is provided with an oil guide hole 131.
[0041] Oil-guiding cotton 140 is installed on the inner wall of the atomizing tube 130;
[0042] A sealing ring 150 is installed circumferentially on the upper end of the atomizing tube 130. The upper side of the sealing ring 150 abuts against the inner wall of the chamber 110, so as to form an oil storage chamber 101 between the chamber 110, the lower sealing seat 120, the atomizing tube 130 and the sealing ring 150. The sealing ring 150 is provided with a ventilation channel connecting its upper and lower sides, so that external gas can enter the oil storage chamber 101 in sequence through the ventilation gap, the ventilation hole 113, the ventilation channel, the oil guide cotton 140 and the oil guide hole 131.
[0043] Specifically, in this embodiment, the oil supply bottle 200 is used to supply oil to the oil storage chamber 100. There are many ways to detach the oil supply bottle 200 and the oil storage chamber 100, such as snap-fit, plug-in, or magnetic connection. No strict limitations are imposed, as long as a ventilation gap connecting them to the outside is formed. Oil storage cotton may or may not be installed in the oil storage chamber 101. When the e-liquid in the oil storage chamber 101 continuously decreases, creating a negative pressure, external air from the atomizing device can sequentially enter the oil storage chamber 101 through the ventilation gap, ventilation hole 113, air passage, oil guide cotton 140, and oil guide hole 131. This replenishes the oil storage chamber 101 with gas, balancing the internal and external air pressure. This ensures that the e-liquid in the oil storage chamber 101 flows smoothly and promptly to the atomizing core 170 in the atomizing tube 130, effectively preventing the atomizing core 170 from dry burning. Because the diameter of the vent 113 is small, such as 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm or others, liquid has difficulty or even cannot pass through (it can only pass through when the air pressure in the oil storage chamber 101 is high), thus avoiding oil leakage.
[0044] It is worth mentioning that when the user continuously inhales the atomizing device, the atomizing core 170 becomes quite hot. This causes the oil-absorbing cotton in the oil storage chamber 101 to expand due to heat, resulting in an increase in the air pressure inside the oil storage chamber 101. The gas inside the oil storage chamber 101 can also be discharged to the outside through the oil guide hole 131, the oil guide cotton 140, the ventilation channel, the air exchange hole 113, and the air exchange gap in sequence to relieve pressure. This achieves air pressure balance inside and outside the oil storage chamber 101, preventing excessive leakage of liquid from the oil-absorbing cotton through the oil guide hole 131 under air pressure.
[0045] In this invention, when the e-liquid in the oil storage chamber 101 continuously decreases, causing a negative pressure to form inside the oil storage chamber 101, external air from the atomizing device can sequentially enter the oil storage chamber 101 through the ventilation gap, ventilation hole 113, ventilation channel, oil guide cotton 140, and oil guide hole 131, thereby replenishing the oil storage chamber 101 with gas in a timely manner. This balances the air pressure inside and outside the oil storage chamber 101, ensuring that the e-liquid in the oil storage chamber 101 can flow smoothly and timely to the atomizing core 170 in the atomizing tube 130, thus effectively preventing the atomizing core 170 from burning dry.
[0046] The venting channel of the sealing ring 150 can be formed in various ways. For example, in some embodiments, the upper side of the sealing ring 150 is provided with a venting groove 151, and the bottom of the venting groove 151 is provided with a venting hole 152 extending to penetrate the lower side of the sealing ring 150. The diameter of the venting hole 152 is 0.5mm-2mm. That is, the venting hole 152 and the venting groove 151 form a venting channel. Since the venting groove 151 has a large volume, it can store gas for timely ventilation. The diameter of the venting hole 152 can be 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, or others, making it difficult or even impossible for liquid to pass through, further preventing oil leakage.
[0047] Furthermore, the venting groove 151 extends in a ring shape along the circumferential direction of the sealing ring 150, and the number of venting holes 152 is at least two, with at least two venting holes 152 arranged opposite to each other. This improves airflow, thereby enhancing ventilation and ensuring timely pressure balance inside and outside the oil storage chamber 101, effectively preventing dry burning and oil leakage of the atomizing core 170.
[0048] In some embodiments, the vent 152 and the air exchange 113 are misaligned. This makes the entire path more complex, further increasing the difficulty for oil to pass through the air exchange path, thereby further preventing oil leakage.
[0049] In some embodiments, the lower side of the sealing ring 150 is provided with an abutment protrusion 153, which abuts against the upper end of the oil-guiding cotton 140. The vent hole 152 is located to the side of the abutment protrusion 153, so that there is a ventilation gap between the vent hole 152 and the upper end of the oil-guiding cotton 140. Similarly, the ventilation gap can store gas and also facilitates gas flow, timely air exchange, and timely pressure balance inside and outside the oil storage chamber 101, thereby effectively preventing dry burning and oil leakage of the atomizing core 170. There are many other ways to increase the gas storage space. For example, in some embodiments, the outer peripheral wall of the oil-guiding cotton 140 is provided with a ventilation notch, which extends to both ends of the oil-guiding cotton 140. The ventilation notch is offset from the oil-guiding hole 131. The offset setting can prevent oil from flowing into the ventilation notch from the oil-guiding hole 131, ensuring that the oil flows along a preset path.
[0050] In some embodiments, the oil-guiding cotton 140 is arranged in a ring shape with a through hole forming in the middle, penetrating both ends of the oil-guiding cotton 140. The oil storage chamber 100 further includes an inner tube 160 and an atomizing core 170. The inner tube 160 is inserted into the through hole and protrudes along both ends of the oil-guiding cotton 140. The inner tube 160 has an oil passage hole connecting its inner and outer sides. The atomizing core 170 is installed inside the inner tube 160. The lower part of the sealing ring 150 is sandwiched between the atomizing tube 130 and the inner tube 160. This improves the installation stability of the sealing ring 150, thereby ensuring the ventilation effect. During operation, the oil in the oil storage chamber 101 flows sequentially through the oil guide hole 131, the oil-guiding cotton 140, and the oil passage hole to the atomizing core 170. Under the power supply of the power supply device 300, the atomizing core 170 heats up, thereby converting the adsorbed oil into a mist for the user to inhale.
[0051] Furthermore, an annular slot 154 is formed on the lower side of the sealing ring 150. The upper end of the inner tube 160 is inserted into the annular slot 154, and the lower end is installed in the lower sealing seat 120. The sealing ring 150 partially extends into the inner tube 160. In this embodiment, the inner tube 160 is inserted into the annular slot 154, which improves the installation stability of the sealing ring 150. At the same time, since the sealing ring 150 extends into the inner tube 160, the sealing effect of the sealing ring 150 is improved, preventing oil leakage.
[0052] Regarding the specific installation method of the oil supply bottle 200 and the oil storage tank 100, in some embodiments, the upper end wall of the tank body 110 extends upward to form an insertion protrusion 111, and the outer peripheral wall of the insertion protrusion 111 is provided with a locking protrusion 112. The lower end wall of the oil supply bottle 200 forms an insertion groove 210, and the side wall of the insertion groove 210 forms a locking groove 211. The insertion protrusion 111 is detachably inserted into the insertion groove 210, and the locking protrusion 112 is detachably inserted into the locking groove 211. That is, in this embodiment, the installation of the oil supply bottle 200 and the oil storage tank 100 is achieved by a combination of insertion and locking, which is simple and quick to install and remove.
[0053] This utility model also proposes an atomizing device, which includes a power supply device 300 and an atomizing device. The power supply device 300 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.
