[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 double-tube atomizers, that is, two coaxially sleeved central air pipes are used, and oil storage cotton is added between the double tubes to alleviate the oil leakage problem and enhance the structural strength of the central air pipe. Please refer to the patent application with application number CN202010966178.7.

[0003] However, in order to facilitate rapid oil conduction, traditional double-tube atomizers have a large number of oil holes opened on the two central air pipes. This results in severe shaking during transportation or carrying, causing the oil in the oil tank to quickly pass through a large number of oil holes, which can easily lead to serious oil leakage accidents.

[0026] See also Figure 1 , which is a schematic structural diagram of a double-tube aerosol generating device according to an embodiment of the present disclosure.

[0027] The double-tube aerosol generating device 10 of one embodiment includes an atomizing assembly 200 and a heating assembly 300. Please refer to Figure 2 The atomizing assembly 200 includes an atomizing cup 100, an atomizing base 220 and an atomizing spacer 240. The atomizing cup 100 has a mist outlet 104. The atomizing base 220 is disposed in the atomizing cup 100. The atomizing base 220 is provided with a vent 206. The vent 206 is communicated with the mist outlet 104. The atomizing spacer 240 is located between the inner wall of the atomizing cup 100 and the atomizing base 220. The atomizing spacer 240 includes a first atomizing sleeve 242, a second atomizing sleeve 244 and a spacer oil-absorbing cotton 210. The first atomizing sleeve 242 is sleeved outside the second atomizing sleeve 244. The spacer oil-absorbing 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 communicated with the mist outlet 104 and the vent 206. An oil storage bin 102 is formed between the first atomizing sleeve 242 and the atomizing cup 100, and the oil storage bin 102 is used to store the e-liquid to be atomized. The first atomizing sleeve 242 is provided with a first oil hole 2022 in communication with the oil storage bin 102, and the second atomizing sleeve 244 is provided with a second oil hole 2024 in communication with the first oil hole 2022. The heating component 300 is disposed in the second atomizing sleeve 244, and the heating component 300 is used to heat the e-liquid to be atomized. The atomizing component 200 also includes an oil-passing retarding cotton 250, which is connected to the first atomizing sleeve 242, and the oil-passing retarding cotton 250 is disposed corresponding to the first oil hole 2022.

[0028] In this embodiment, during transportation, the first oil-passing hole 2022 is blocked by the oil-passing retarding cotton 250, and the tobacco oil to be atomized in the oil storage bin 102 must first pass through the oil-passing retarding cotton 250 before reaching the first oil-passing hole 2022, so that the rate at which the tobacco oil to be atomized passes through the atomization isolation kit 240 is slowed down, thereby reducing the probability of leakage of the tobacco oil to be atomized when shaken, and effectively improving the anti-leakage capability of the double-tube aerosol generating device.

[0029] In another embodiment, in addition to the oil-passing retarding cotton, the first oil-passing hole may also 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.

[0030] In one embodiment, see Figure 2, the oil-passing retarding cotton 250 is sleeved outside the first atomizing sleeve 242. In the present embodiment, the oil-passing retarding cotton 250 is located on the first atomizing sleeve 242. Specifically, the oil-passing retarding cotton 250 is sleeved on the outer wall of the first atomizing sleeve 242. The oil-passing retarding cotton 250 covers the first oil-passing hole 2022, so that the oil-passing retarding cotton 250 is located between the first atomizing sleeve 242 and the smoke oil to be atomized. The oil-passing retarding cotton 250 reduces the rate at which the smoke oil to be atomized in the oil storage bin 102 is introduced into the first oil-passing 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.

[0031] In one embodiment, see Figure 2 The atomizing base 220 is provided with a first connecting groove 208, and part of the atomizing partition kit 240 is clamped in the first connecting groove 208. In this embodiment, the first connecting groove 208 is located on the atomizing base 220, and the opening of the first connecting groove 208 faces the atomizing partition kit 240, so that part of the atomizing partition kit 240 is conveniently accommodated in the first connecting groove 208, so that the atomizing partition kit 240 is clamped with the atomizing base 220, which effectively improves the installation stability of the atomizing partition kit 240 in the atomizing cup 100.

[0032] For further information, see Figure 2 , the atomizing base 220 is provided with a second connecting groove 201 connected to the first connecting groove 208, and at least part of the oil-passing retarding cotton 250 is clamped in the second connecting groove 201. In this embodiment, the second connecting groove 201 is located on the atomizing base 220, and the second connecting groove 201 and the first connecting groove 208 are jointly opened on the atomizing base 220, and the second connecting groove 201 and the first connecting groove 208 are kept in communication with each other, so that the second connecting groove 201 and the first connecting groove 208 form a common clamping position. Part of the atomizing spacer 240 is located in the first connecting groove 208, and at least part of the oil-passing retarding cotton 250 is clamped in the second connecting groove 201, so that the oil-passing retarding cotton 250 is abutted against the atomizing spacer 240, so as to facilitate the oil-passing retarding cotton 250 to align with the first oil-passing hole 2022, so that the oil-passing retarding cotton 250 reduces the oil leakage probability of the atomizing spacer 240.

[0033] In one embodiment, see Figure 2, the atomizer base 220 includes a base clamping portion 222 and a base fixing portion 224 connected to each other, the base clamping portion 222 abuts against the inner wall of the atomizer cup 100 and the atomizer spacer 240 respectively, and the base fixing portion 224 is located on the side of the base clamping portion 222 away from the atomizer spacer 240. In this embodiment, the base clamping portion 222 is sleeved in the atomizer cup 100, and the base clamping portion 222 provides an installation and fixing point for the atomizer spacer 240, and also facilitates the installation of the oil-passing slow cotton 250. Specifically, the second connecting groove 201 and the first connecting groove 208 are both opened on the base clamping portion 222. The base fixing portion 224 serves as the bottom of the atomizer base 220, which is convenient for limiting the base clamping portion 222 in the atomizer cup 100. For example, the base fixing portion 224 is also connected to the bottom end of the atomizer cup 100.

[0034] For further information, see Figure 2 The base clamping portion 222 is provided with a third connection groove 203, and part of the base fixing portion 224 is clamped in the third connection groove 203. In this embodiment, the third connection groove 203 is located on the base clamping portion 222. Specifically, the opening of the third connection groove 203 is away from the atomizing partition sleeve 240, and the third connection groove 203 accommodates part of the base fixing portion 224, so that the base fixing portion 224 is clamped with the base clamping portion 222, which effectively improves the connection stability between the base fixing portion 224 and the base clamping portion 222.

[0035] In one embodiment, see Figure 3 , the atomization assembly 200 also includes a top connection seat 260, which is respectively connected to the inner wall of the atomization cup 100 and the atomization partition kit 240, and the top connection seat 260 is provided with a first air guide hole 205 connected to the mist outlet hole 104. In this embodiment, the top connection seat 260 is arranged at the upper end of the atomization partition kit 240, that is, the top connection seat 260 is located at the end of the atomization partition kit 240 away from the atomization base 220, and the top connection seat 260 serves as a sealing plugging component between the atomization partition kit 240 and the inner wall of the atomization cup 100. Specifically, part of the top connection seat 260 is clamped between the first atomization sleeve 242 and the second atomization sleeve 244, so that the seal between the atomization partition kit 240 and the inner wall of the atomization cup 100 is tighter. The first air guide 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 heating component 300 after heating and atomization.

[0036] For further information, see Figure 3 The atomization assembly 200 further includes an oil storage cotton 270, which is located on a side of the top connection seat 260 away from the atomization spacer 240, and is respectively connected to the inner wall of the atomization cup 100 and the top connection seat 260, and is provided with a second air guide hole 207 connected to the first air guide hole 205. In this embodiment, the oil storage cotton 270 is located between the top connection seat 260 and the inner wall of the atomization cup 100, and the second air guide hole 207 on the oil storage cotton 270 is connected to the interior of the second atomization sleeve 244. The oil storage cotton 270 is used to absorb the smoke oil to be atomized that leaks from between the top connection seat 260 and the inner wall of the atomization cup 100, and can also absorb the excess smoke oil to be atomized in the second atomization sleeve 244, thereby preventing the smoke oil to be atomized from being discharged through the mist outlet hole 104 of the atomization cup 100.
