[0003] The press-type oil filling is a method of filling oil in existing atomizers for the convenience of users to fill oil by themselves.

[0025] The embodiment of the present application provides an oil locking and anti-leakage device for an electronic atomization device and an electronic atomization device, which solves the technical problem that during the oil filling process of the existing electronic cigarette structure, the oil in the oil tank is easy to leak from the mouthpiece, causing inconvenience to the user.

[0026] Embodiment 1:

[0027] Figure 1 This is a schematic diagram of the structure of the oil-locking and anti-leakage device of the electronic atomization device according to the embodiment of the present application. Figure 2 This is another structural schematic diagram of the oil locking and anti-leakage device of the electronic atomization device described in an embodiment of the present application.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an oil locking and leak-proof device for an electronic atomization device, which is applied to the electronic atomization device. The electronic atomization device includes an atomization component and an oil storage element 62 for providing smoke oil to the atomization component. The atomization component is provided with an oil inlet pipe 11, a pressing element 5, an oil tank 1 and an atomization element 2. The leak-proof device includes a leak-proof element for reducing or removing the impact force of the smoke oil on the atomization element 2. The leak-proof element 3 is wrapped and installed on the outer wall surface of the atomization element 2.

[0029] In the embodiment of the present application, the oil locking and leak prevention device of the electronic atomization device uses the leak prevention element 3 to enable the electronic atomization device to effectively prevent the oil in the oil tank 1 from leaking from the mouthpiece through the atomization element 2 while satisfying the function of pressing to feed oil, thereby improving the operability of the electronic atomization device for pressing to feed oil.

[0030] It should be noted that the anti-leakage element 3 is installed on the atomizing element 2 to increase the oil locking of the atomizing element 2, thereby reducing the impact force of the smoke oil on the atomizing element 2 and avoiding oil leakage.

[0031] In the embodiment of the present application, the oil tank 1 is provided with an air inlet, an air outlet and an oil inlet pipe 11; the atomizing element 2 is arranged in the oil tank 1, and the atomizing element 2 is connected to the air inlet and the air outlet; the air inlet and the air outlet are arranged opposite to each other, and the oil inlet pipe 11 is arranged on the same side as the air inlet. The above-mentioned structural design is an existing structure and will not be described in detail.

[0032] It should be noted that the atomizing element 2 can be selected as an atomizing core. In this embodiment, the oil storage element 62 can be selected as an oil storage bottle, and the oil outlet of the oil storage bottle is connected to the oil inlet pipeline 11 through.

[0033] The present application provides an oil-locking and leak-proof device for an electronic atomization device, which is applied to the electronic atomization device. The electronic atomization device includes an atomization component and an oil storage element for providing smoke oil to the atomization component. The atomization component is provided with an oil inlet pipeline, a pressing element, an oil bin and an atomization element. The leak-proof device includes a leak-proof element for slowing down or removing the impact force of the smoke oil on the atomization element, and the leak-proof element is wrapped and installed on the outer wall surface of the atomization element. The oil-locking and leak-proof device for the electronic atomization device increases the oil-locking of the atomization element through the leak-proof element while satisfying the function of pressing the oil inlet, thereby slowing down the impact force of the smoke oil on the atomization element and avoiding oil leakage. At the same time, it can effectively prevent the smoke oil in the oil bin from leaking from the cigarette holder, thereby improving the operability of the electronic atomization device for pressing the oil inlet; it solves the technical problem that the smoke oil in the oil bin of the existing electronic cigarette structure is easy to leak from the cigarette holder during the oil inlet process, causing inconvenience to the user.

[0034] like Figure 1 As shown, in one embodiment of the present application, the leak-proof element 3 is an oil-locking layer 301 made of cotton, and the oil-locking layer 301 is used to increase the oil-locking strength of the atomizing element 2 to mitigate or remove the impact force of the smoke oil in the oil tank 1 on the atomizing element 2.

[0035] It should be noted that in order to increase the oil locking strength of the atomizing element 2, one or more layers of cotton can be provided as required to form an oil locking layer 301. The oil locking layer 301 is wrapped and provided on the outer wall surface of the atomizing element 2. Adding the oil locking layer 301 on the outer wall surface of the atomizing element 2 can increase the oil locking of the atomizing element 2, so that the smoke oil in the oil tank 1 will not directly impact the atomizing element 2, thereby avoiding oil leakage. The pressure in the oil tank 1 will not increase when the electronic atomizing device is pressed to enter the oil, resulting in an increase in the strength of the smoke oil impacting the atomizing element 2, causing the smoke oil to leak easily from the mouthpiece 611.

[0036] In one embodiment of the present application, the oil-locking layer 301 is wrapped and installed on the outer wall surface of all the atomizing elements 2 located in the oil tank 1 , or the oil-locking layer 301 is wrapped and installed on the outer wall surface of the oil inlet located at the atomizing element 2 .

[0037] It should be noted that the length of the oil-locking layer 301 can be set according to the size specifications of the outer wall surface of the atomizing element 2, so that the oil-locking layer 301 can completely wrap the atomizing element 2. In order to save costs and prevent oil leakage, the oil-locking layer 301 is only provided on the outer wall surface of the oil inlet of the atomizing element 2. For example, the oil-locking layer 301 is provided at the oil inlet position of the atomizing element 2, and the other outer wall surfaces of the atomizing element 2 in the oil tank 1 are not wrapped with the oil-locking layer 301.

[0038] In order to further increase the oil locking capability of the atomizing element 2 and to more effectively mitigate the impact force of the e-liquid on the atomizing element 2 , in one embodiment of the present application, a highly active adsorption material is filled between the oil locking layer 301 and the outer wall surface of the atomizing element 2 .

[0039] It should be noted that the highly active adsorption material can be silica gel.
