Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to an atomization device and atomization equipment that allows for air exchange without oil leakage. 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. An oil inlet channel connects the oil reservoir and the atomizing coil, allowing the oil in the reservoir to flow through the inlet channel 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. This mist then flows out through the mouthpiece's outlet channel for the user to inhale.
[0003] As the amount of oil in the reservoir decreases, a negative pressure is generated within it. Without ventilation, the oil cannot penetrate the porous ceramic atomizing core, easily leading to core clogging. Therefore, ventilation of the reservoir is necessary, i.e., replenishing it with gas. However, existing ventilation channels are poorly designed, easily resulting in oil leakage from the reservoir through these channels. Therefore, a leak-proof atomizing device with ventilation capability is needed to prevent oil leakage from the reservoir through the ventilation channels. Utility Model Content
[0004] The main purpose of this invention is to provide an atomizing device that prevents oil leakage during ventilation, thereby solving the problem that existing atomizing devices are prone to oil leakage from the oil storage chamber through the ventilation channel.
[0005] To achieve the above objectives, the atomizing device with air exchange and no oil leakage proposed in this utility model includes:
[0006] The cargo box is open at its lower end;
[0007] An installation component is installed at the lower end of the tank body to enclose and form an oil storage cavity. The installation component forms an installation cavity and an oil inlet channel connecting the installation cavity and the oil storage cavity.
[0008] A ceramic atomizing core is installed in the mounting cavity. The upper side of the ceramic atomizing core is connected to the oil inlet channel, and the lower side is enclosed by the mounting assembly to form an atomizing cavity.
[0009] The oil inlet channel has a vent on its side wall, the vent having a width of 0.1–0.3 mm and a cross-sectional area of 0.01–0.09 mm². 2 The installation component and the inner wall of the chamber form a ventilation channel, the ventilation channel has at least one bend, and the two ends of the ventilation channel are respectively connected to the ventilation port and the atomizing chamber.
[0010] Optionally, the mounting components include:
[0011] The bracket has an oil inlet channel and an installation cavity inside, a venting recess at the top, and a venting groove extending from the top to the bottom of the bracket on the outer wall.
[0012] A sealing cap is provided on the upper end of the bracket and has an oil passage at the position corresponding to the oil inlet channel. The top wall of the sealing cap and the ventilation recess form the ventilation port. The outer peripheral wall abuts against the inner wall of the chamber and the inner peripheral wall covers part of the ventilation groove.
[0013] The base is sealed and installed at the lower port of the chamber. The upper end of the base is open and sleeved on the lower end of the bracket to cover part of the opening of the ventilation groove. The inner wall of the base, the inner wall of the mounting cavity, and the lower side of the ceramic atomizing core form the atomizing cavity. The ventilation groove communicates with the atomizing cavity.
[0014] Optionally, the outer peripheral wall of the support is further provided with a plurality of air-containing grooves, all of which are connected to the ventilation groove, and the plurality of air-containing grooves are arranged at intervals along the height direction of the support.
[0015] Optionally, the outer diameter of the lower end of the bracket is smaller than the outer diameter of the middle part of the bracket, so as to form a limiting step on the outer wall of the bracket, and the top wall of the base abuts against the step surface of the limiting step.
[0016] Optionally, the outer peripheral wall of the base is provided with an installation groove, and a sealing ring is installed in the installation groove, the sealing ring abutting against the inner wall of the chamber.
[0017] Optionally, the air-exchange leak-proof atomizing device further includes oil-absorbing cotton, which is installed on the base and located below the ceramic atomizing core. The end of the air exchange channel near the atomizing chamber is positioned close to the oil-absorbing cotton.
[0018] Optionally, the air-exchange leak-proof atomizing device further includes an elastic sealing block and a support column. An abutting step is formed at the connection between the oil inlet channel and the mounting cavity. The upper side of the elastic sealing block abuts against the step surface of the abutting step, and the lower side abuts against the upper side of the ceramic atomizing core. The support column is installed at the lower end of the mounting assembly, and the upper end of the support column supports and abuts against the lower side of the ceramic atomizing core.
[0019] Optionally, the abutment step is provided with a ventilation opening, the width of which is 0.1–0.3 mm and the cross-sectional area is 0.01–0.09 mm². 2 There is a ventilation gap between the sidewall of the ceramic atomizing core and the sidewall of the mounting cavity, and the ventilation gap connects the ventilation notch and the atomizing cavity.
[0020] Optionally, there are two support pillars, one a positive conductive pillar and the other a negative conductive pillar.

[0021] This utility model also proposes an atomizing device, including a power supply device and the above-mentioned air-exchange oil-leakage atomizing device, wherein the power supply device is used to provide electrical energy to the air-exchange oil-leakage atomizing device.
[0022] The technical solution of this utility model, by setting up an air exchange port and an air exchange channel, allows the gas in the atomization chamber located on the lower side of the ceramic atomizing core to sequentially pass through the air exchange channel, air exchange port, and oil inlet channel to reach the upper side of the ceramic atomizing core. Thus, when a negative pressure is generated in the oil storage chamber, the gas in the atomization chamber can replenish the upper side of the ceramic atomizing core, balancing the air pressure on the upper and lower sides of the ceramic atomizing core. This allows the oil to continue to enter the ceramic atomizing core normally, preventing clogging. Because the air exchange port is small in size and the air exchange channel is bent, oil has difficulty passing through the entire air exchange channel, making it difficult or even impossible for oil from the oil storage chamber to enter the atomization chamber, thus preventing oil leakage.

[0035] The following will mainly describe the specific structure of the atomizing device that prevents oil leakage during air exchange.
[0036] Reference Figures 1 to 4 In this embodiment of the invention, the atomizing device with air exchange and no oil leakage includes:
[0037] The compartment is 100mm thick, with its lower end open.
[0038] An installation component is installed at the lower end of the tank body 100 to enclose and form an oil storage cavity 101. The installation component forms an installation cavity and an oil inlet channel 211 that connects the installation cavity and the oil storage cavity 101.
[0039] A ceramic atomizing core 300 is installed in the mounting cavity. The upper side of the ceramic atomizing core 300 is connected to the oil inlet channel 211, and the lower side is enclosed by the mounting assembly to form an atomizing cavity 203.
[0040] The oil inlet channel 211 has a vent 201 on its side wall. The vent 201 has a width of 0.1–0.3 mm and a cross-sectional area of 0.01–0.09 mm². 2 The installation assembly and the inner wall of the chamber 100 form a ventilation channel 202. The ventilation channel 202 has at least one bend, and the two ends of the ventilation channel 202 are respectively connected to the ventilation port 201 and the atomizing chamber 203.
[0041] Specifically, in this embodiment, the oil in the oil storage chamber 101 flows into the ceramic atomizing core 300 through the oil inlet channel 211. The power supply device supplies power to the ceramic atomizing core 300, causing it to heat up and convert the adsorbed oil into a mist for the user to inhale. As the amount of oil in the oil storage chamber 101 decreases, a negative pressure is generated inside the oil storage chamber 101. At this time, the gas in the atomizing chamber 203 can enter the oil inlet channel 211 through the ventilation channel 202 and the ventilation port 201 in sequence. In this way, the gas in the oil inlet channel 211 and the oil storage chamber 101 are replenished with gas, quickly balancing the air pressure on the upper and lower sides of the ceramic atomizing core 300, so that the oil can continue to enter the ceramic atomizing core 300 normally and avoid clogging.
[0042] Since the ventilation port 201 is relatively small, for example, its width can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, or other sizes, the cross-sectional area of the ventilation port 201 is related to its width, and can be 0.01mm². 2 0.0225mm 2 0.04mm 2 0.0625mm 2 Or other means prevent the oil in the oil storage chamber 101 from passing through the vent 201, thus preventing the oil in the oil storage chamber 101 from leaking out. Because the vent 202 has at least one bend, the length and complexity of the vent 202 are increased within a limited space, thereby increasing the difficulty for the oil to pass through the entire vent 202. Thus, even in special circumstances such as high pressure, where a small amount of oil in the oil storage chamber 101 passes through the vent 201, the oil will be stored in the bend of the vent 202 and will be difficult or even impossible to enter the atomizing chamber 203, thus avoiding oil leakage.
[0043] The technical solution of this utility model, by setting an air exchange port 201 and an air exchange channel 202, allows the gas in the atomizing chamber 203 located on the lower side of the ceramic atomizing core 300 to sequentially pass through the air exchange channel 202, the air exchange port 201, and the oil inlet channel 211 to reach the upper side of the ceramic atomizing core 300. Thus, when a negative pressure is generated in the oil storage chamber 101, the gas in the atomizing chamber 203 can replenish the upper side of the ceramic atomizing core 300, balancing the air pressure on the upper and lower sides of the ceramic atomizing core 300. This allows the oil to continue to enter the ceramic atomizing core 300 normally, preventing clogging. Because the air exchange port 201 is small and the air exchange channel 202 is bent, it is difficult for the oil to pass through the air exchange port 201 and the entire air exchange channel 202. Therefore, the oil in the oil storage chamber 101 is unlikely to enter the atomizing chamber 203, preventing oil leakage.
[0044] Regarding the composition of the mounting assembly, in some embodiments, the mounting assembly includes a bracket 210, a sealing cap 220, and a base 230. The bracket 210 has an oil inlet channel 211 and a mounting cavity formed inside, a venting recess 212 at the top, and a venting groove 213 extending from the top to the bottom of the bracket 210 on its outer wall. The sealing cap 220 covers the upper end of the bracket 210 and has an oil passage corresponding to the position of the oil inlet channel 211. The top wall of the sealing cap 220 and the venting recess 212 enclose each other to form a... The vent 201 has its outer peripheral wall abutting against the inner wall of the chamber 100, and its inner peripheral wall covering part of the opening of the vent groove 213. The base 230 is sealed and installed at the lower port of the chamber 100. The upper end of the base 230 is open and fitted onto the lower end of the bracket 210 to cover part of the opening of the vent groove 213. The inner wall of the base 230, together with the inner wall of the mounting cavity and the lower side of the ceramic atomizing core 300, forms the atomizing cavity 203. The vent groove 213 communicates with the atomizing cavity 203. The sealing cap 220 is made of an elastic material, such as silicone or rubber, to have good elastic deformation capability, thereby improving the sealing performance of the vent 201 formed by the bracket 210. The sealing cap 220 abuts against the inner wall of the chamber 100, improving the sealing effect of the oil storage cavity 101 and preventing oil leakage. The ventilation groove 213 is bent, with its two ends connected to the ventilation recess 212 and the atomizing chamber 203, respectively. The groove openings near the ventilation recess 212 and the atomizing chamber 203 are covered by the sealing cap 220 and the base 230, respectively. This improves the sealing performance of both ends of the enclosed ventilation channel 202, ensuring that the gas in the atomizing chamber 203 enters the ventilation channel 202 according to a preset path, and the gas in the ventilation channel 202 flows out through the ventilation port 201 according to a preset path, thus improving the ventilation effect.
[0045] In some embodiments, the outer peripheral wall of the support 210 is further provided with a plurality of air-containing grooves 214, each communicating with the ventilation groove 213, and the plurality of air-containing grooves 214 are arranged at intervals along the height direction of the support 210. In this way, the air-containing area is increased, and when the oil storage chamber 101 is under negative pressure, sufficient gas can be quickly replenished into the oil storage chamber 101, thereby improving the ventilation efficiency.
[0046] In some embodiments, the outer diameter of the lower end of the bracket 210 is smaller than the outer diameter of the middle part of the bracket 210, so as to form a limiting step 215 on the outer wall of the bracket 210, and the top wall of the base 230 abuts against the step surface of the limiting step 215. In this way, the bracket 210 is effectively prevented from moving up and down or swaying left and right relative to the base 230, improving the installation stability of the base 230 and the bracket 210, thereby improving the reliability of the atomizing device.
[0047] In some embodiments, the outer peripheral wall of the base 230 is provided with an installation groove, and a sealing ring 240 is installed in the installation groove. The sealing ring 240 abuts against the inner wall of the chamber 100. The sealing ring 240 fills the gap between the base 230 and the chamber 100, preventing oil from flowing out of the gap, thereby preventing oil leakage and improving the sealing performance of the atomizing device.
[0048] In some embodiments, the leak-proof atomizing device further includes an oil-absorbing cotton 400, which is mounted on the base 230 and located below the ceramic atomizing core 300. The end of the ventilation channel 202 near the atomizing chamber 203 is positioned close to the oil-absorbing cotton 400. Thus, in special circumstances, if a small amount of oil enters the atomizing chamber 203, the oil-absorbing cotton 400 can absorb and trap the oil, preventing leakage from the atomizing device.
[0049] In some embodiments, the leak-proof atomizing device further includes an elastic sealing block 500 and a support column. A step 216 is formed at the connection between the oil inlet channel 211 and the mounting cavity. The upper side of the elastic sealing block 500 abuts against the step surface of the step 216, and the lower side abuts against the upper side of the ceramic atomizing core 300. The support column is installed at the lower end of the mounting assembly, and the upper end of the support column supports and abuts against the lower side of the ceramic atomizing core 300. This arrangement sandwiches the ceramic atomizing core 300 between the elastic sealing block 500 and the support column, improving the installation stability of the ceramic atomizing core 300. The elastic sealing block 500 has elastic deformation capability and can be made of silicone, rubber or other elastic materials. It can not only abut against the ceramic atomizing core 300 to make it installed firmly, but also fill the gap between the upper side of the ceramic atomizing core 300 and the abutting step 216, so that the oil will not flow from the periphery of the ceramic atomizing core 300 into the atomizing chamber 203. That is, the elastic sealing block 500 also plays a sealing role.
[0050] In some embodiments, the abutment step 216 is provided with a ventilation opening 217, the ventilation opening 217 having a width of 0.1–0.3 mm and a cross-sectional area of 0.01–0.09 mm². 2 A ventilation gap 218 is provided between the sidewall of the ceramic atomizing core 300 and the sidewall of the mounting cavity, the ventilation gap 218 connecting the ventilation notch 217 and the atomizing cavity 203. Thus, the width of the ventilation notch 217 can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, or other values, and the cross-sectional area of the ventilation notch 217 is related to its width, and can be 0.01mm. 2 0.0225mm 2 0.04mm 2 0.0625mm 2 Alternatively, the gas in the atomizing chamber 203 can also sequentially reach the upper side of the ceramic atomizing core 300 through the ventilation gap 218 and ventilation notch 217, replenishing the upper side of the ceramic atomizing core 300 with gas, quickly balancing the air pressure between the upper and lower sides of the ceramic atomizing core 300, thus allowing the oil to continue to enter the ceramic atomizing core 300 normally, avoiding clogging. Because the ventilation notch 217 is small, it prevents oil from passing through, thus avoiding oil leakage. In other words, this embodiment provides an additional air supply path, improving the air supply speed and effect, and further preventing clogging. Furthermore, there are two ventilation notches 217, located on opposite sides of the abutment step 216, each ventilation notch 217 having a corresponding ventilation gap 218 connected to it. This further improves the ventilation effect. Moreover, it ensures that in special circumstances, such as strong vibration causing slight movement of the ceramic atomizing core 300 and blocking one ventilation gap 218, the other ventilation gap 218 can still provide ventilation.
[0051] In some embodiments, there are two support columns: a positive conductive column 610 and a negative conductive column 620. The positive conductive column 610 supports and abuts against the positive electrode of the ceramic atomizing core 300, and the negative conductive column 620 supports and abuts against the negative electrode of the ceramic atomizing core 300. Thus, the positive conductive column 610 and the negative conductive column 620 provide both conductivity and support, eliminating the need for additional support members for the ceramic atomizing core 300, reducing material usage, and simplifying the internal structure of the atomizing device.
[0052] This utility model also proposes an atomizing device, which includes a power supply device and a leak-proof atomizing device with ventilation. The power supply device provides electrical energy to the leak-proof atomizing device. The specific structure of the leak-proof 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.
[0053] 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.
