Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an atomization device and atomization equipment. Background Technology

[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 chamber, and an atomizing coil housed within the atomizing chamber. The atomizing chamber and the oil reservoir are connected via an oil inlet, allowing the oil in the reservoir to flow through the inlet and be drawn into 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. The mist then flows out through the outlet channel of the mouthpiece for the user to inhale.

[0003] When the ambient temperature or pressure is high, the air pressure inside the e-liquid reservoir increases. Under these conditions, excessive e-liquid can seep from the inlet into the atomizing chamber and then leak out of the mouthpiece. Consequently, users will directly inhale e-liquid when vaping, reducing the user experience. Therefore, an atomizing device with a pressure relief function is needed to prevent e-liquid from leaking out of the mouthpiece. Utility Model Content

[0004] The main objective of this invention is to provide an atomizing device that addresses the problem of excessive oil leakage from the oil storage chamber into the atomizing chamber via the oil inlet and then out of the nozzle in existing atomizing devices.

[0008] A pressure relief assembly is installed in the mounting hole. The pressure relief assembly forms an air passage, an insertion hole communicating with the oil reservoir and the air passage respectively, and a pressure relief air passage communicating with the air passage and the outside of the sealing seat respectively. The width of the pressure relief air passage is 0.2-0.6 mm, and the cross-sectional area is 0.04-0.36 mm². 2 ;

[0009] The exhaust pipe is inserted into the insertion hole at its lower end.

[0010] An elastic seal is installed at the upper end of the exhaust pipe. The elastic seal has a slit at the upper end of the exhaust pipe so that when the gas pressure in the oil storage chamber is higher than that outside, the gas in the oil storage chamber causes the gap of the slit to widen, and the gas is discharged out of the oil storage chamber in sequence through the slit, the inside of the exhaust pipe, the gas passage chamber and the pressure relief passage.

[0011] Optionally, the elastic seal includes a sleeve with openings at both ends and a sealing block connected to the inner wall of the sleeve. The sleeve is fitted onto the exhaust pipe, and the sealing block covers the upper end of the exhaust pipe. The thickness of the sealing block is 0.1 to 0.4 mm, and the slit is formed in the sealing block.

[0012] Optionally, the sealing block is disposed near the upper end wall of the sleeve, and the upper end of the sleeve has an air passage notch communicating with the slit.

[0013] Optionally, the inner top wall of the chamber is recessed upward to form an air-receiving groove, which is located directly above the exhaust pipe.

[0014] Optionally, the inner top wall of the compartment is provided with at least two enclosing plates protruding downwards, and the at least two enclosing plates enclose a bubble cavity in a non-closed ring shape, and the elastic seal is located in the bubble cavity.

[0015] Optionally, the pressure relief assembly includes:

[0016] An elastic mounting cylinder is inserted into the mounting hole. The lower end of the elastic mounting cylinder is open, and the upper end is a sealed end with an insertion hole.

[0017] A pressure relief cylinder is inserted into the elastic mounting cylinder from the lower end of the elastic mounting cylinder. An insertion protrusion is formed at the upper end of the pressure relief cylinder. The insertion protrusion is inserted into the insertion hole. The insertion hole extends from the end wall of the insertion protrusion into the interior of the pressure relief cylinder.

[0018] A sealing plug is inserted into the lower end of the pressure relief cylinder, and together with the inner wall of the pressure relief cylinder, forms the air passage and pressure relief air channel.

[0019] Optionally, the cylinder wall of the pressure relief cylinder is provided with a pressure relief groove, and the groove wall of the pressure relief groove and the outer wall of the sealing plug form the pressure relief air passage.

[0020] Optionally, the wall of the insertion hole is provided with an exhaust groove, the width of the exhaust groove is 0.1 to 0.4 mm, the groove depth is 0.1 to 0.4 mm, the groove wall of the exhaust groove and the outer wall of the exhaust pipe form an exhaust channel, and the exhaust channel is connected to the air passage.

[0021] The present invention 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.

[0022] Optionally, the power supply device includes a mounting bracket and a battery and circuit board installed in the mounting bracket. A receiving groove is formed on the upper side of the mounting bracket, and an oil-absorbing cotton is installed in the receiving groove. The oil-absorbing cotton is located near the outlet of the venting channel.

[0023] The technical solution of this utility model, by setting a pressure relief component, inserts the exhaust pipe into the insertion hole of the pressure relief component, and installs an elastic sealing element at the upper end. The upper port of the sealing element has a slit, so that when the pressure inside the oil storage chamber is higher than that outside, the high pressure inside the oil storage chamber can make the slit larger, allowing gas or oil to enter the exhaust pipe through the slit. The gas can be discharged out of the oil storage chamber through the air passage and the pressure relief air passage in sequence, and the oil can flow and be stored in the air passage. In this way, the pressure of the oil storage chamber is relieved, so that the air pressure inside and outside the oil storage chamber is balanced, effectively preventing the phenomenon that the oil in the oil storage chamber seeps out excessively from the oil inlet into the atomizing chamber and then leaks out from the nozzle.

[0039] The following will mainly describe the specific structure of the atomizing device.

[0040] Reference Figures 1 to 6 In this embodiment of the invention, the atomizing device includes:

[0041] The compartment is 100mm thick, with its lower end open.

[0042] A sealing seat 200 is installed at the lower end of the chamber 100 to form an oil storage cavity 101 by surrounding the chamber 100. The sealing seat 200 is provided with mounting holes that penetrate its upper and lower sides.

[0043] A pressure relief assembly 300 is installed in the mounting hole. The pressure relief assembly 300 forms an venting chamber 301, an insertion hole 321 communicating with the oil storage chamber 101 and the venting chamber 301 respectively, and a pressure relief air passage 302 communicating with the venting chamber 301 and the outside of the sealing seat 200 respectively. The width of the pressure relief air passage 302 is 0.2-0.6 mm, and the cross-sectional area is 0.04-0.36 mm². 2 ;

[0044] The lower end of the exhaust pipe 400 is inserted into the insertion hole 321;

[0045] An elastic seal 500 is installed at the upper end of the exhaust pipe 400. The elastic seal 500 has a slit 521 at the upper port of the exhaust pipe 400. When the gas pressure in the oil storage chamber 101 is higher than that outside, the gas in the oil storage chamber 101 causes the gap of the slit 521 to widen. The gas then passes through the slit 521, the inside of the exhaust pipe 400, the gas passage 301, and the pressure relief passage 302 to be discharged outside the oil storage chamber 101.

[0046] Specifically, in this embodiment, the amount of e-liquid dispensed from the oil storage chamber 101 can be controlled so that when the atomizing device is upright, the height of the slit 521 is higher than the e-liquid surface. Since the slit 521 is located in the elastic seal 500, the slit 521 can expand under pressure. When the air pressure inside the oil storage chamber 101 is higher than the outside due to temperature or pressure, the air pressure inside the oil storage chamber 101 can make the gap of the slit 521 larger, allowing gas to enter the exhaust pipe 400 through the slit 521, and then be discharged from the oil storage chamber 101 through the air passage 301 and the pressure relief passage 302. In this way, the pressure of the oil storage chamber 101 is relieved, and the air pressure inside and outside the oil storage chamber 101 is quickly balanced, effectively preventing the phenomenon that the e-liquid in the oil storage chamber 101 seeps excessively from the oil inlet into the atomizing chamber and then leaks out from the mouthpiece.

[0047] It is worth mentioning that, because the pressure relief duct 302 is relatively small—for example, its width can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, or other sizes—its cross-sectional area is related to its width, and can be as small as 0.04mm². 2 0.06mm 2 0.09mm 2 0.16mm 2 0.25mm 2Alternatively, this ensures that even if the oil can flow through the slit 521 and the interior of the exhaust pipe 400 into the air passage 301, it will not flow out through the pressure relief passage 302, thus storing the oil in the air passage 301 to prevent leakage. When a negative pressure is generated in the oil storage chamber 101, a small amount of oil in the air passage 301 returns to the oil storage chamber 101 via the original path. Therefore, when the atomizing device is laid flat or upside down, even if the slit 521 is blocked by oil, if the pressure inside the oil storage chamber 101 is higher than the external pressure, the high pressure inside the oil storage chamber 101 causes the gap in the slit 521 to widen, allowing a small amount of oil to enter the exhaust pipe 400 through the slit 521 and then flow into the air passage 301 for storage. This also achieves pressure relief; when a negative pressure is generated in the oil storage chamber 101, a small amount of oil in the air passage 301 returns to the oil storage chamber 101 via the original path.

[0048] The technical solution of this utility model is to set up a pressure relief component 300, and insert the exhaust pipe 400 into the insertion hole 321 of the pressure relief component 300. An elastic sealing element 500 is installed at the upper end. The upper port of the sealing element has a slit 521. When the pressure inside the oil storage chamber 101 is higher than that outside, the high pressure inside the oil storage chamber 101 can make the slit 521 larger, so that gas or oil can enter the exhaust pipe 400 through the slit 521. The gas can be discharged from the oil storage chamber 101 through the air passage 301 and the pressure relief air passage 302 in sequence, and the oil can flow and be stored in the air passage 301. In this way, the pressure of the oil storage chamber 101 is relieved, so that the air pressure inside and outside the oil storage chamber 101 is balanced, effectively preventing the phenomenon that the oil in the oil storage chamber 101 seeps out excessively from the oil inlet into the atomizing chamber and then leaks out from the nozzle.

[0049] In some embodiments, the elastic seal 500 includes a sleeve 510 with openings at both ends and a sealing block 520 connected to the inner wall of the sleeve 510. The sleeve 510 is fitted onto the exhaust pipe 400, and the sealing block 520 covers the upper port of the exhaust pipe 400. The thickness of the sealing block 520 is 0.1–0.4 mm, and the slit 521 is formed in the sealing block 520. That is, the thickness of the sealing block 520 is relatively small, for example, it can be set to 0.15 mm, 0.2 mm, 0.3 mm, or 0.35 mm, etc., so that the sealing block 520 is easily forced to deform under pressure, thereby causing the slit 521 to become larger. In this way, gas or liquid can quickly pass through the slit 521, thereby ultimately increasing the pressure relief speed. This allows the atomizing device to quickly restore the air pressure balance inside and outside the oil storage chamber 101, effectively preventing the phenomenon of excessive oil seeping from the oil inlet into the atomizing chamber and then leaking out from the nozzle from the oil storage chamber 101. The sealing block 520 is positioned close to the upper wall of the sleeve 510, and the upper end of the sleeve 510 has an air passage notch 511 communicating with the slit 521. Thus, the sealing block 520 is positioned as close as possible to the top of the oil storage chamber 101, allowing more e-liquid to be injected into the oil storage chamber 101, increasing the amount of e-liquid discharged from the oil storage chamber 101. The air passage notch 511 ensures that airflow can smoothly pass through the slit 521.

[0050] In some embodiments, the inner top wall of the chamber 100 is recessed upward to form a gas-containing groove 102, which is located directly above the exhaust pipe 400. This increases the amount of oil discharged from the oil storage chamber 101 while providing sufficient space for gas release to facilitate depressurization.

[0051] In some embodiments, the inner top wall of the reservoir 100 is provided with at least two enclosing plates 103 protruding downwards. The at least two enclosing plates 103 enclose a non-closed annular bubble-trapping cavity 104, and the elastic seal 500 is located in the bubble-trapping cavity 104. In this way, when bubbles are generated in the oil storage cavity 101, the movement of the bubbles is restricted, so that the bubbles are located in the bubble-trapping cavity 104, thereby approaching the slit 521. When high pressure is generated in the oil storage cavity 101, the gas can quickly pass through the slit 521 and finally be discharged from the pressure relief vent 302, thus achieving rapid pressure relief.

[0052] Regarding the composition of the pressure relief assembly 300, in some embodiments, the pressure relief assembly 300 includes an elastic mounting cylinder 310, a pressure relief cylinder 320, and a sealing plug 330. The elastic mounting cylinder 310 is inserted into the mounting hole, with its lower end open and its upper end sealed with an insertion hole. The pressure relief cylinder 320 is inserted into the elastic mounting cylinder 310 from its lower end, and its upper end has an insertion protrusion that inserts into the insertion hole. The insertion hole 321 extends from the end wall of the insertion protrusion into the interior of the pressure relief cylinder 320. The sealing plug 330 is inserted into the lower end of the pressure relief cylinder 320, and together with the inner wall of the pressure relief cylinder 320, forms the air passage 301 and the pressure relief air passage 302. In this embodiment, both the elastic mounting cylinder 310 and the sealing plug 330 are elastic components, and the material can be silicone, rubber or other materials, so as to have good elasticity, thereby improving the sealing performance of the air passage 301 and the pressure relief air passage 302.

[0053] Furthermore, the pressure relief cylinder 320 has a pressure relief groove 324 on its cylinder wall. The groove wall of the pressure relief groove 324 and the outer wall of the sealing plug 330 enclose the pressure relief passage 302. That is, the outer wall of the sealing plug 330 seals the opening of the pressure relief groove 324. Since the sealing plug 330 has sealing properties, the enclosed pressure relief passage 302 has a good sealing effect, thereby allowing the gas to be discharged along a preset path and improving the pressure relief effect.

[0054] In some embodiments, the wall of the insertion hole 321 is provided with an exhaust groove 322. The width of the exhaust groove 322 is 0.1-0.4 mm, and the depth is 0.1-0.4 mm. The wall of the exhaust groove 322 and the outer wall of the exhaust pipe 400 enclose an exhaust channel 323, which communicates with the air passage 301. The exhaust groove 322 is relatively small in size; for example, the width of the exhaust groove 322 can be selected as 0.15 mm, 0.2 mm, 0.3 mm, or 0.35 mm, and the depth can be selected as 0.15 mm, 0.2 mm, 0.3 mm, or 0.35 mm, etc. In this way, when the atomizing device is inverted, the gas can be discharged sequentially through the exhaust channel 323, the air passage 301, and the pressure relief channel 302, thereby achieving pressure relief. Because the venting groove 322 is small, oil has difficulty passing through. Even if it can pass through under relatively high pressure in the oil storage chamber 101, the oil will be stored in the venting chamber 301 and will not leak out.

[0055] The present invention also proposes an atomizing device, which includes a power supply device and an atomizing device, wherein 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 the 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.

[0056] In some embodiments, the power supply device includes a mounting bracket 600 and a battery 710 and a circuit board 720 mounted within the mounting bracket 600. A receiving groove is formed on the upper side of the mounting bracket 600, and an oil-absorbing cotton 800 is installed in the receiving groove. The oil-absorbing cotton 800 is positioned near the outlet of the venting channel. The oil-absorbing cotton 800 can absorb oil, so that in special circumstances, if oil flows out from the pressure relief channel 302, the oil can be absorbed by the oil-absorbing cotton 800, preventing the oil from flowing onto the battery 710 or the circuit board 720.

[0057] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
