Description

Technical Field

[0001] The present disclosure relates to the technical field of atomizers, and in particular to a pressure-balanced atomizer and a pressure-balanced atomizing device. Background Art

[0002] In the prior art, the electronic atomization device is mainly composed of an atomizer and a body component. The atomizer generally includes a liquid storage chamber and an atomization component. The liquid storage chamber is used to store the atomizable medium, and the atomization component is used to heat and atomize the atomizable medium to form an aerosol that can be consumed by the smoker; the body component is used to provide energy to the atomizer. For some common large-capacity atomizers, in order to increase the oil storage capacity of the liquid storage chamber as much as possible, that is, to increase the oil storage capacity of the liquid storage chamber, it is usually adopted to increase the internal central air pipe to expand the internal volume of the liquid storage chamber. For example, a glass fiber tube is added to the upper end of the original central air pipe to increase its length. Please refer to the patent application with application number CN202210954526.8.

[0003] However, due to the increase in the length of the central air pipe, the overall rigidity of the central air pipe is affected. During the high-temperature process of atomization, the structure of the central air pipe is easily damaged, which will seriously cause a large amount of liquid in the liquid storage chamber to flow out. For this reason, a double air pipe is usually adopted, and oil storage cotton is added between the double air pipes to alleviate the oil leakage problem. It can also enhance the structural strength of the central air pipe. Please refer to the patent application with application number CN202010966178.7.

[0004] However, no matter which of the above methods is used to form the atomizer, the interior of the central air pipe is relatively isolated from the liquid storage chamber, the central air pipe is connected to the external environment, and the liquid storage chamber remains relatively closed. In high altitude or high-altitude environments, such as flying, mountaineering, or rapid changes in altitude, the air pressure in the central air pipe will be significantly lower than the air pressure in the liquid storage chamber, which can easily cause the air pressure in the liquid storage chamber to squeeze the central air pipe outward, thereby easily causing the central air pipe to deform and crack, or even burst, which is not conducive to normal use.

When the air pressure of the central air pipe is less than the air pressure of the oil storage chamber, that is, low pressure appears outside the central air pipe, and the air pressure at the top of the oil storage chamber is high pressure, at this time, the gas at the top of the oil storage chamber is convenient to timely guide the gas in the oil storage chamber through the interconnected microporous ventilation channels and air leakage holes, so that the air pressure in the oil storage chamber is released, avoiding the squeezing of the central air pipe, and effectively improving the anti-negative pressure burst capability of the air pressure balance atomizer.

[0033] See also Figure 1 , which is a schematic diagram of the structure of a pressure-balanced atomizer according to an embodiment of the present disclosure.

[0034] The pressure-balanced atomizer 10 of one embodiment includes an oil cup 100. Figure 2The air pressure balanced atomizer 10 also includes an oil guide assembly 200 and an atomizing heating assembly 300. The oil guide assembly 200 includes an oil storage cotton 210, a sealing base 220 and two sleeved central air pipes 230. The sealing base 220 is connected to the inner wall of the oil cup 100. The oil storage cotton 210 is arranged between the two central air pipes 230. The two central air pipes 230 are respectively connected to the inner wall of the oil cup 100 and the sealing base 220. An oil storage cavity 102 is formed between the central air pipe 230, the sealing base 220 and the oil cup 100. Each of the central air pipes 230 is provided with an oil inlet hole 202. The oil inlet hole 202 is connected to the oil storage cavity 102. The central air pipe 230 is also respectively connected to the air outlet of the oil cup 100 and the air inlet of the sealing base 220. The atomizing heating component 300 is disposed in the central air pipe 230, and the atomizing heating component 300 is disposed corresponding to the oil inlet hole 202. Figure 3 The air pressure balanced atomizer 10 also includes an air pressure balanced tube 400, which is connected to one of the central air pipes 230. Each of the central air pipes 230 is also provided with an air leakage hole 204. The air leakage hole 204 and the air pressure balanced tube 400 are both arranged away from the oil inlet hole 202. The air pressure balanced tube 400 has a plurality of microporous ventilation channels, and each of the microporous ventilation channels is connected to the air leakage hole 204.

[0035] In this embodiment, when the air pressure in the central air pipe 230 is lower than the air pressure in the oil storage chamber 102, that is, low pressure appears outside the central air pipe 230, while the air pressure at the top of the oil storage chamber 102 is high pressure, the gas at the top of the oil storage chamber 102 is convenient for timely discharge of the gas in the oil storage chamber 102 through the interconnected microporous ventilation channels and the air leakage holes 204, thereby releasing the air pressure in the oil storage chamber, avoiding squeezing of the central air pipe 230, and effectively improving the negative pressure burst prevention capability of the pressure-balanced atomizer.

[0036] In another embodiment, the air pressure balance tube further has a pressure relief zone of a preset pressure difference, and the pressure relief zone of the preset pressure difference is used to connect at least two of the microporous ventilation channels when the air pressure difference between the central air pipe and the oil storage chamber is greater than or equal to the preset pressure difference. The pressure relief zone of the preset pressure difference is a gap that can be opened or closed on the outer wall of the air pressure balance tube, for example, the pressure relief zone of the preset pressure difference is a closable zone of the preset pressure difference, and specifically, the pressure relief zone of the preset pressure difference is any one of a straight gap, a cross gap, an arc gap, and a special-shaped gap. The pressure relief zone of the preset pressure difference is used to connect at least two of the microporous ventilation channels when the pressure difference between the central air pipe and the oil storage chamber is greater than or equal to the preset pressure difference. Specifically, the preset pressure difference is in the range of 0.2 standard atmospheres to 0.8 standard atmospheres. At this time, the air pressure in the oil storage chamber is greater than the air pressure in the central air pipe, and the pressure difference between the oil storage chamber and the central air pipe is greater than or equal to the preset pressure difference. The pressure relief zone of the preset pressure difference is in an open state to connect multiple adjacent microporous ventilation channels, so that when a negative pressure occurs, multiple microporous ventilation channels are interconnected, and the pressure relief zone of the preset pressure difference expands the opening of the microporous ventilation channel to facilitate the rapid discharge of the gas in the liquid storage chamber, thereby effectively improving the pressure relief rate of the oil storage chamber.

[0037] In another embodiment, the air pressure balance tube is a glass fiber tube or a butter tube, and the air pressure balance tube achieves ventilation and liquid blocking functions by means of the microporous ventilation channel thereon, that is, the microporous ventilation channel is a channel with a tiny pore structure, and its pore size allows air to pass through, but it acts as a barrier for liquids with larger molecular particle sizes, thereby achieving ventilation without leakage.

[0038] In one embodiment, see Figure 3, the air pressure balance pipe 400 is located between the central air pipe 230 and the oil storage cotton 210. In this embodiment, the air pressure balance pipe 400 serves as an air pressure balance adjustment component in a negative pressure environment inside the central air pipe 230, specifically, it is realized by the opening and closing state of the pressure relief zone of the preset pressure difference on the air pressure balance pipe 400. The air pressure balance pipe 400 is arranged between the central air pipe 230 and the oil storage cotton 210. For example, the air pressure balance pipe 400 is sleeved on the outer wall of the oil storage cotton 210, that is, the outer central air pipe 230 of the two central air pipes 230 is sleeved on the outer wall of the air pressure balance pipe 400, so that the gas in the oil storage chamber 102 can pass through the air leakage hole 204 of the outer central air pipe 230 and the pressure relief zone of the preset pressure difference in sequence. When the pressure-balanced atomizer is in a negative pressure state, specifically, the internal air pressure of the central air pipe 230 is between 0.2 standard atmospheres and 0.8 standard atmospheres, and the internal air pressure of the oil storage chamber 102 is 1 standard atmosphere. At this time, the top air of the oil storage chamber 102 is affected by the difference and flows toward the outside. The top air of the oil storage chamber 102 first passes through the air leakage hole 204 of the outer central air pipe 230, and when reaching the pressure-balanced pipe 400, it squeezes the pressure relief area of ​​the preset pressure difference to open the pressure relief area of ​​the preset pressure difference, and then passes through the gap of the oil storage cotton 210, and finally passes through the air leakage hole 204 of the inner central air pipe 230 into the external environment, so that the internal air pressure of the oil storage chamber 102 is released.

[0039] For further information, see Figure 3, the air pressure balance pipe 400 is sleeved on the inner central air pipe 230 of the two central air pipes 230, and the pressure relief area of ​​the preset pressure difference is arranged corresponding to the air leakage hole 204 of the inner central air pipe 230. In this embodiment, the air pressure balance pipe 400 serves as an air pressure balance adjustment component in a negative pressure environment inside the central air pipe 230, specifically, it is realized by the opening and closing state of the pressure relief area of ​​the preset pressure difference on the air pressure balance pipe 400. The air pressure balance pipe 400 is sleeved on the inner central air pipe 230 of the two central air pipes 230, that is, the air pressure balance pipe 400 is located between the inner central air pipe 230 of the two central air pipes 230 and the oil storage cotton 210, so that the gas in the oil storage chamber 102 can pass through the pressure relief area of ​​the preset pressure difference and the air leakage hole 204 of the inner central air pipe 230 in sequence. When the pressure-balanced atomizer is in a negative pressure state, specifically, the internal air pressure of the central air pipe 230 is between 0.2 standard atmospheres and 0.8 standard atmospheres, and the internal air pressure of the oil storage chamber 102 is 1 standard atmosphere. At this time, the top air of the oil storage chamber 102 is affected by the difference and flows toward the outside. The top air of the oil storage chamber 102 first passes through the air leakage hole 204 of the outer central air pipe 230, and then passes through the gap of the oil storage cotton 210. After that, the gas breaks through the pressure relief area of ​​the preset pressure difference when reaching the pressure-balanced tube 400, and finally passes into the external environment through the air leakage hole 204 of the inner central air pipe 230, so that the oil storage chamber 102 is connected with the external environment, thereby avoiding the squeezing and deformation of the central air pipe 230 by the air in the oil storage chamber 102.

[0040] In another embodiment, see Figure 4, the inner wall of the outer central air pipe 230 of the two central air pipes 230 is in contact with the air pressure balance pipe 400, and the pressure relief area of ​​the preset pressure difference is arranged corresponding to the air leakage hole 204 of the outer central air pipe 230. In this embodiment, the air pressure balance pipe 400 is used as an air pressure balance adjustment component in a negative pressure environment inside the central air pipe 230. Specifically, it is realized by the opening and closing state of the pressure relief area of ​​the preset pressure difference on the air pressure balance pipe 400. The air pressure balance pipe 400 is arranged between the outer central air pipe 230 and the oil storage cotton 210, and the air pressure balance pipe 400 is sleeved on the outer wall of the oil storage cotton 210, so that the gas in the oil storage cavity 102 can pass through the air leakage hole 204 of the outer central air pipe 230 and the pressure relief area of ​​the preset pressure difference in sequence. Under negative pressure, the internal air pressure of the central air pipe 230 is lower than the internal air pressure of the oil storage chamber 102. For example, the external environment connected to the central air pipe 230 is a high-altitude environment. At this time, there is a pressure difference in the top air of the oil storage chamber 102. The top air of the oil storage chamber 102 first passes through the air leakage hole 204 of the outer central air pipe 230. The relatively high-pressure gas squeezes and opens the pressure relief area of ​​the preset pressure difference, so that the gas can pass through the gap of the oil storage cotton 210 and the air leakage hole 204 of the inner central air pipe 230 in turn, so that the oil storage chamber 102 is connected to the external environment, so that the air pressure in the oil storage chamber 102 can be quickly released to the external environment.

[0041] In another embodiment, the air pressure balance tube 400 can also be sleeved on the outer wall of the outer central air pipe 230 of the two central air pipes 230, or the inner central air pipe 230 of the two central air pipes 230 can be sleeved on the outer wall of the air pressure balance tube 400. When negative pressure occurs, the pressure relief area of ​​the preset pressure difference on the air pressure balance tube 400 can be opened to quickly release the air pressure in the oil storage chamber 102, thereby effectively avoiding the bursting of the central air pipe 230.

[0042] In one embodiment, there are at least two air leakage holes 204 and at least two pressure relief areas of the preset pressure difference, and each air leakage hole 204 is correspondingly arranged with a pressure relief area of ​​the preset pressure difference. In this embodiment, under negative pressure, the air leakage holes 204 are correspondingly connected with the pressure relief areas of the preset pressure difference, so that there are at least two air guide channels between the oil storage chamber 102 and the external environment. Through at least two air guide channels, it is convenient to quickly guide the gas in the oil storage chamber 102, so that the air pressure in the oil storage chamber 102 is released more quickly.

[0043] In another embodiment, at least two of the pressure relief areas of the preset pressure difference are arranged relative to each other. In this embodiment, the pressure relief areas of the preset pressure difference are arranged one by one with the air leakage holes 204. Specifically, each of the pressure relief areas of the preset pressure difference is connected to a corresponding air leakage hole 204 of the central air pipe 230 of the outer layer, and each of the pressure relief areas of the preset pressure difference is also synchronously connected to a corresponding air leakage hole 204 of the central air pipe 230 of the inner layer, so that the air leakage holes 204 of the central air pipes 230 of the inner and outer layers are synchronously connected to the corresponding pressure relief areas of the preset pressure difference. At least two of the pressure relief areas of the preset pressure difference are arranged relative to each other. Specifically, there are at least two symmetrically arranged pressure relief areas of the preset pressure difference on the air pressure balance pipe 400, so that the positions of the at least two pressure relief areas of the preset pressure difference remain symmetrical, that is, there are at least two pressure relief areas of the preset pressure difference on the air pressure balance pipe 400 to maintain a 180-degree symmetrical arrangement. In this way, under negative pressure conditions, no matter in what posture the air pressure-balanced atomizer is laid flat, it is always possible to ensure that at least one pressure relief area with a preset pressure difference is in an upward state, thereby ensuring that at least one air guide channel is in a conducting state.

[0044] In another embodiment, the aperture of the air leakage hole 204 of the inner central air pipe 230 of the two central air pipes 230 is larger than the aperture of the air leakage hole 204 of the outer central air pipe 230 of the two central air pipes 230. In this embodiment, there are two central air pipes 230, and the two central air pipes 230 are sleeved, that is, the two central air pipes 230 are coaxially sleeved together. An oil storage cotton 210 is arranged between the two central air pipes 230. The oil storage cotton 210 serves as a temporary storage component for the smoke oil in the oil storage chamber 102. The oil storage cotton 210 is an integrated cotton with a certain gap, which can be used for the top air circulation of the oil storage chamber 102. The aperture of the leak hole 204 of the inner central air tube 230 is set to be larger than the aperture of the leak hole 204 of the outer central air tube 230. Under the condition of ensuring gas circulation, when the oil level in the oil storage chamber 102 exceeds the position of the leak hole 204, the oil in the oil storage chamber 102 needs to pass through the leak hole 204 with a smaller aperture before entering the oil storage cotton 210. At this time, the leak hole 204 of the outer central air tube 230 can effectively reduce the rate at which the oil in the oil storage chamber 102 is introduced into the oil storage cotton 210 through the leak hole 204, thereby improving the oil leakage prevention capability of the air pressure balance atomizer. The aperture of the leak hole is the equivalent diameter or average diameter of the leak hole, for example, the diameter after the area of ​​the leak hole is equivalent to the circular area; for example, the average value of each diameter in the leak hole is obtained.

[0045] In another embodiment, the number of the leak holes 204 of the inner central air tube 230 of the two central air tubes 230 is greater than the number of the leak holes 204 of the outer central air tube 230 of the two central air tubes 230. In this embodiment, the number of the leak holes 204 of the inner central air tube 230 is set to be greater than the number of the leak holes 204 of the outer central air tube 230. Under the condition of ensuring gas circulation, when the smoke oil level in the oil storage chamber 102 exceeds the position of the leak holes 204, the smoke oil in the oil storage chamber 102 needs to pass through the leak holes 204 with a smaller number of holes before entering the oil storage cotton 210. At this time, the passages provided by the leak holes 204 of the outer central air tube 230 are reduced, slowing down the rate of the smoke oil entering the oil storage cotton 210 through the leak holes 204, further reducing the rate at which the smoke oil in the oil storage chamber 102 is introduced into the oil storage cotton 210 through the leak holes 204, and further improving the anti-leakage capability of the air pressure balance atomizer.

[0046] In another embodiment, the air leakage holes 204 on each of the central air pipes 230 are evenly distributed. In this embodiment, there are multiple air leakage holes 204 on the inner and outer central air pipes 230, and the distance between two adjacent air leakage holes 204 on each central air pipe 230 is the same, so that the air pressure distribution of the gas passing through each central air pipe 230 is even, and the gas pressure in the oil storage chamber 102 is effectively distributed to each air leakage hole 204, thereby improving the air pressure balancing ability of the oil storage chamber 102.

[0047] During the actual transportation or carrying of the air pressure balance atomizer, due to the severe shaking, the smoke oil in the oil tank quickly passes through a large number of oil holes, which can easily lead to serious oil leakage accidents.

[0048] See also Figure 5 The pressure-balanced atomizer 10 includes an oil guide assembly 200 and an atomization heating assembly 300. Figure 6The oil guide assembly 200 includes an oil cup 100, a sealing base 220 and an atomizing isolation kit 240. The oil cup 100 has an air outlet 104. The sealing base 220 is arranged in the oil cup 100. The sealing base 220 is provided with an air inlet 206. The air inlet 206 is communicated with the air outlet 104. The atomizing isolation kit 240 is located between the inner wall of the oil cup 100 and the sealing base 220. The atomizing isolation kit 240 includes an oil storage cotton 210 and two central air pipes. Specifically, the outer central air pipe is a first atomizing sleeve 242, and the inner central air pipe is a second atomizing sleeve 244. The first atomizing sleeve 242 is sleeved outside the second atomizing sleeve 244, the oil storage cotton 210 is filled between the first atomizing sleeve 242 and the second atomizing sleeve 244, the interior of the second atomizing sleeve 244 is connected to the air outlet 104 and the air inlet 206; an oil storage chamber 102 is formed between the first atomizing sleeve 242 and the oil cup 100, the oil storage chamber 102 is used to store the smoke oil to be atomized, and the first atomizing sleeve 242 is provided with A first oil guide hole 2022 is connected to the oil storage chamber 102, and the second atomization sleeve 244 is provided with a second oil guide hole 2024 connected to the first oil guide hole 2022; the atomization heating component 300 is arranged in the second atomization sleeve 244, and the atomization heating component 300 is used to heat the tobacco oil to be atomized; wherein the first oil guide hole 2022 is the oil inlet hole on the outer central air pipe 230, and the second oil guide hole 2024 is the oil inlet hole on the inner central air pipe 230.

[0049] The oil guide assembly 200 further includes an atomizing oil-isolating cotton 250 , which is connected to the first atomizing sleeve 242 , and the atomizing oil-isolating cotton 250 is disposed corresponding to the first oil guide hole 2022 .

[0050] In this embodiment, during transportation, the first oil guide hole 2022 is blocked by the atomizing oil-isolating cotton 250, and the smoke oil to be atomized in the oil storage chamber 102 must first pass through the atomizing oil-isolating cotton 250 before reaching the first oil guide hole 2022, so that the rate at which the smoke oil to be atomized passes through the atomizing isolation kit 240 is slowed down, thereby reducing the probability of leakage of the smoke oil to be atomized when shaking, effectively improving the anti-leakage ability of the pressure-balanced atomizer.

[0051] In another embodiment, in addition to the atomized oil-isolating cotton, the first oil guide hole may be blocked by any one of a microporous membrane, a breathable fabric or a glass fiber tube, which has a liquid-proof and breathable function, that is, it allows gas to pass through but can block liquid from passing through.

[0052] In one embodiment, see Figure 6, the atomizing oil-separating cotton 250 is sleeved outside the first atomizing sleeve 242. In this embodiment, the atomizing oil-separating cotton 250 is located on the first atomizing sleeve 242. Specifically, the atomizing oil-separating cotton 250 is sleeved on the outer wall of the first atomizing sleeve 242. The atomizing oil-separating cotton 250 covers the first oil guide hole 2022, so that the atomizing oil-separating cotton 250 is located between the first atomizing sleeve 242 and the smoke oil to be atomized. The atomizing oil-separating cotton 250 reduces the rate at which the smoke oil to be atomized in the oil storage chamber 102 is introduced into the first oil guide hole 2022, effectively slowing down the efficiency of the smoke oil to be atomized passing through the atomizing isolation kit 240, thereby improving the oil leakage prevention capability.

[0053] In one embodiment, see Figure 6 The sealing base 220 is provided with a first clamping groove 208, and part of the atomizing isolation kit 240 is clamped in the first clamping groove 208. In this embodiment, the first clamping groove 208 is located on the sealing base 220, and the opening of the first clamping groove 208 faces the atomizing isolation kit 240, so that part of the atomizing isolation kit 240 is easily accommodated in the first clamping groove 208, so that the atomizing isolation kit 240 is clamped with the sealing base 220, which effectively improves the installation stability of the atomizing isolation kit 240 in the oil cup 100.

[0054] For further information, see Figure 6 The sealing base 220 is provided with a second clamping groove 201 which is in communication with the first clamping groove 208, and at least part of the atomizing oil-isolating cotton 250 is clamped in the second clamping groove 201. In this embodiment, the second clamping groove 201 is located on the sealing base 220, and the second clamping groove 201 and the first clamping groove 208 are jointly provided on the sealing base 220, and the second clamping groove 201 and the first clamping groove 208 are kept in communication with each other, so that the second clamping groove 201 and the first clamping groove 208 form a common clamping position. Part of the atomizing isolation kit 240 is located in the first clamping groove 208, and at least part of the atomizing oil-isolating cotton 250 is clamped in the second clamping groove 201, so that the atomizing oil-isolating cotton 250 is convenient for abutting against the atomizing isolation kit 240, thereby aligning the atomizing oil-isolating cotton 250 with the first oil guide hole 2022, so that the atomizing oil-isolating cotton 250 reduces the probability of oil leakage of the atomizing isolation kit 240.

[0055] In one embodiment, see Figure 6The sealing base 220 includes a base body 222 and a bottom cover 224 which are connected to each other. The base body 222 abuts against the inner wall of the oil cup 100 and the atomizing isolation kit 240 respectively, and the bottom cover 224 is located on the side of the base body 222 away from the atomizing isolation kit 240. In this embodiment, the base body 222 is sleeved in the oil cup 100, and the base body 222 provides an installation and fixing point for the atomizing isolation kit 240, and also facilitates the installation of the atomizing oil-isolating cotton 250. Specifically, the second clamping groove 201 and the first clamping groove 208 are both provided on the base body 222. The bottom cover 224 serves as the bottom of the sealing base 220, which is convenient for limiting the base body 222 in the oil cup 100. For example, the bottom cover 224 is also connected to the bottom end of the oil cup 100.

[0056] For further information, see Figure 6 The base body 222 is provided with a third snap-fitting groove 203, and part of the bottom cover 224 is snap-fitted into the third snap-fitting groove 203. In this embodiment, the third snap-fitting groove 203 is located on the base body 222. Specifically, the opening of the third snap-fitting groove 203 faces away from the atomizing partition kit 240. The third snap-fitting groove 203 accommodates part of the bottom cover 224, so that the bottom cover 224 is snap-fitted with the base body 222, which effectively improves the connection stability between the bottom cover 224 and the base body 222.

[0057] In one embodiment, see Figure 7 , the oil guide assembly 200 also includes an atomizing top seat 260, which is respectively connected to the inner wall of the oil cup 100 and the atomizing partition kit 240, and the atomizing top seat 260 is provided with a first through hole 205 connected to the air outlet 104. In this embodiment, the atomizing top seat 260 is arranged at the upper end of the atomizing partition kit 240, that is, the atomizing top seat 260 is located at the end of the atomizing partition kit 240 away from the sealing base 220, and the atomizing top seat 260 serves as a sealing plugging component between the atomizing partition kit 240 and the inner wall of the oil cup 100. Specifically, part of the atomizing top seat 260 is clamped between the first atomizing sleeve 242 and the second atomizing sleeve 244, so that the seal between the atomizing partition kit 240 and the inner wall of the oil cup 100 is tighter. The first through hole 205 is in communication with the interior of the second atomizing sleeve 244 , so as to facilitate the discharge of smoke generated by the atomizing and heating component 300 after heating and atomization.

[0058] For further information, see Figure 7The oil guide assembly 200 further includes a top oil-absorbing cotton 270, which is located on the side of the atomizing top seat 260 away from the atomizing spacer 240, and is respectively connected to the inner wall of the oil cup 100 and the atomizing top seat 260. The top oil-absorbing cotton 270 is provided with a second through hole 207 connected to the first through hole 205. In this embodiment, the top oil-absorbing cotton 270 is located between the atomizing top seat 260 and the inner wall of the oil cup 100, and the second through hole 207 on the top oil-absorbing cotton 270 is connected to the inside of the second atomizing sleeve 244. The top oil-absorbing cotton 270 is used to absorb the oil to be atomized leaking from between the atomizing top seat 260 and the inner wall of the oil cup 100, and can also absorb the excess oil to be atomized in the second atomizing sleeve 244, thereby preventing the oil to be atomized from being led out through the air outlet 104 of the oil cup 100.

[0059] In one of the embodiments, the present disclosure also relates to an air pressure balanced atomization device, including the air pressure balanced atomizer described in any of the above embodiments. In this embodiment, the air pressure balanced atomizer includes an oil cup, an oil guide assembly, and an atomization heating assembly; the oil guide assembly includes oil storage cotton, a sealing base, and two sleeved central air pipes, the sealing base is connected to the inner wall of the oil cup, the oil storage cotton is arranged between the two central air pipes, the two central air pipes are respectively connected to the inner wall of the oil cup and the sealing base, an oil storage cavity is formed between the central air pipe, the sealing base, and the oil cup, each of the central air pipes is provided with an oil inlet hole, and the oil inlet hole is connected to the oil storage cavity, The central air pipe is also connected to the air outlet of the oil cup and the air inlet of the sealing base respectively; the atomizing heating component is arranged in the central air pipe, and the atomizing heating component is arranged corresponding to the oil inlet hole; the air pressure balanced atomizer also includes an air pressure balanced pipe, which is connected to one of the central air pipes, and each of the central air pipes is also provided with an air leakage hole, and the air leakage hole and the air pressure balanced pipe are arranged away from the oil inlet hole, and the air pressure balanced pipe has a plurality of microporous ventilation channels, and each of the microporous ventilation channels is connected to the air leakage hole. When the air pressure of the central air pipe is less than the air pressure of the oil storage chamber, that is, low pressure appears outside the central air pipe, and the air pressure at the top of the oil storage chamber is high pressure, at this time, the gas at the top of the oil storage chamber is convenient to timely guide the gas in the oil storage chamber through the interconnected microporous ventilation channels and the air leakage holes, so that the air pressure in the oil storage chamber is released, avoiding the squeezing of the central air pipe, and effectively improving the anti-negative pressure burst capability of the air pressure balanced atomizer.
