Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] An embodiment of the present application discloses an electronic atomization device. Refer to Figures 1 to 4 , an electronic atomization device includes a housing 1, a bracket 2, and an atomization core 5. Specifically, an accommodation chamber 11 is provided inside the housing 1 for placing components. The bracket 2 is arranged at the middle position of the accommodation chamber 11. The bracket 2 is made of silica gel material. The side wall of the bracket 2 is in sealed contact with the inner side wall of the accommodation chamber 11 to divide the accommodation chamber 11 into two chambers, namely a working chamber 111 and a liquid storage chamber 112. The working chamber 111 is used for arranging components such as a battery, a PCB board, and the atomization core 5. The liquid storage chamber 112 is used for storing the liquid to be atomized. The liquid can be substances such as e-liquid. In this embodiment, the liquid storage chamber 112 and the working chamber 111 are vertically distributed up and down. In other embodiments, the liquid storage chamber 112 and the working chamber 111 can also be distributed horizontally left and right. A ventilation pipe 3 is arranged in the liquid storage chamber 112. The ventilation pipe 3 is in the shape of a long cylindrical tube. The ventilation pipe 3 is vertically arranged in the liquid storage chamber 112. And the inside of the ventilation pipe 3 is set as a hollow air passage 31. The lower end of the hollow air passage 31 penetrates out of the liquid storage chamber 112 and is connected to the external atmosphere. A communication hole is arranged on the bracket 2. And the upper end of the hollow air passage 31 is connected to the air inlet end of the atomization core 5 through the communication hole. A liquid guiding medium 4 is arranged in the liquid storage chamber 112. The liquid guiding medium 4 is in the shape of a long cylindrical tube. The liquid guiding medium 4 is sleeved on the outer side wall of the ventilation pipe 3. The lower end of the liquid guiding medium 4 extends towards the bottom of the liquid storage chamber 112. And the upper end of the liquid guiding medium 4 penetrates into the working chamber 111 through the communication hole on the bracket 2. And the outer side wall of the liquid guiding medium 4 is in contact with the inner side wall of the communication hole. The upper end of the liquid guiding medium 4 is used for inserting the atomization core 5. In this embodiment, the structural form of the liquid guiding medium 4 is oil guiding cotton. When the user uses the electronic atomization device, through the suction effect, the liquid in the liquid storage chamber 112 is transported from the bottom of the liquid guiding medium 4 to the upper end of the liquid guiding medium 4 and enters the atomization core 5. That is, when the electronic atomization device is in use, there is always liquid entering the atomization core 5 through the liquid guiding medium 4. Then it is not necessary to frequently invert the electronic atomization device, which helps to improve the use experience and convenience of the electronic atomization device.
[0029] Refer to Figure 2 and Figure 3In order to prevent the liquid-conducting medium 4 from sliding and stacking up and down along the outer wall of the ventilation tube 3, a fixing sleeve 12 is provided in the liquid storage chamber 112. The fixing sleeve 12 is cylindrical and can be made of metal material. The fixing sleeve 12 is sleeved on the ventilation tube 3. The upper end of the fixing sleeve 12 can extend into the bracket 2, and the lower end abuts against the bottom of the liquid storage chamber 112. The bottom of the fixing sleeve 12 is provided with a liquid inlet hole 121 connected with the liquid-conducting medium 4. The fixing sleeve 12 is connected to the ventilation tube 3 and the bottom of the liquid storage chamber 112. An annular space will be formed between the parts for placing the lower end of the liquid-conducting medium 4, and the inner wall of the fixed sleeve 12 will abut against the outer wall of the liquid-conducting medium 4 to provide a predetermined friction force to prevent the lower end of the liquid-conducting medium 4 from sliding and stacking along the ventilation pipe 3 in the vertical direction to affect the liquid-conducting effect. At the same time, the liquid inlet hole 121 is provided at the bottom of the fixed sleeve 12, so that the speed at which the liquid is immersed in the liquid-conducting medium 4 can be limited, and the liquid-conducting medium 4 can be prevented from leaking out of the air channel 31 due to too much immersion of the liquid.
[0030] Reference Figure 2 and Figure 3 In order to improve the practicality of the electronic atomization device, the following settings are correspondingly made. First, the shell 1 is provided with a liquid injection hole 13 on the part of the liquid storage chamber 112. The liquid injection hole 13 is arranged at the bottom of the liquid storage chamber 112. The liquid injection hole 13 is filled with a sealing portion 131. The sealing portion 131 is made of an elastic material, such as silicone. The sealing portion 131 is used to seal the liquid injection hole 13. At the same time, the sealing portion 131 is tightly inserted in the liquid injection hole 13 to achieve a detachable connection. When the liquid storage chamber 112 needs to be injected, the electronic atomization device is inverted, and then the sealing portion 131 is pulled out to inject liquid. After the injection is completed, the sealing portion 131 is inserted into the liquid injection hole 13, so that the electronic atomization device can be reused.
[0031] Reference Figure 2 and Figure 3, secondly, an air regulating valve 6 is provided on a part of the housing 1 in the liquid storage chamber 112. The air regulating valve 6 is arranged at the bottom of the housing 1 and is movably arranged at the bottom of the housing 1. The air regulating valve 6 is used to block the lower opening of the middle air passage 31. An air regulating hole 61 is provided on the air regulating valve 6. There are multiple air regulating holes 61, and the sizes of the multiple air regulating holes 61 are different. Under the action of the movable connection of the air regulating valve 6, one of the multiple air regulating holes 61 will be correspondingly communicated with the middle air passage 31, and external air enters the middle air passage 31 from the correspondingly corresponding air regulating hole 61. In this embodiment, the air regulating valve 6 is rotationally connected to the housing 1 through a pin, and the air regulating valve 6 is in the shape of a rectangular parallelepiped plate. The air regulating holes 61 are provided in two, and the two air regulating holes 61 are symmetrically arranged along the axis of the air regulating valve 6. At the same time, the air regulating valve 6 can also be set in the shape of a cylindrical plate, and the multiple air regulating holes 61 are distributed along the center of the air regulating valve 6. In other embodiments, the air regulating valve 6 can be slidably connected to the housing 1, and different apertures of the air regulating holes 61 are made to correspond to the middle air passage 31 through sliding. Therefore, the intake air volume of the atomizing core 5 is changed through different air regulating holes 61, so that the suction resistance of the electronic atomizing device can be adjusted, and thus the electronic atomizing device can be suitable for different people.
[0032] Referring to Figures 2 to 4 , thirdly, a liquid storage shell 7 is provided in the working chamber 111. The liquid storage shell 7 and the bracket 2 form an additional chamber 71. The atomizing core 5 is arranged in the additional chamber 71. At the same time, a communication hole communicates the additional chamber 71 with the liquid storage chamber 112, so that the liquid guiding medium 4 penetrates into the additional chamber 71 through the communication hole. A liquid storage medium 72 is arranged in the additional chamber 71. The liquid storage medium 72 is integrally in the shape of a cylindrical ring. The liquid storage medium 72 is sleeved on the upper end of the liquid guiding medium 4, and the inner side wall of the liquid storage medium 72 abuts against the outer side wall of the liquid guiding medium 4. The liquid storage medium 72 can store liquid, and the liquid storage medium 72 can be filled with liquid during the production process of the electronic atomizing device, which can further increase the liquid storage capacity of the electronic atomizing device.
[0033] In order to prevent liquids such as condensate or e-liquid from leaking out from the lower end of the middle air passage 31, a liquid absorbing cotton 8 is provided at the upper end of the ventilation pipe 3. The liquid absorbing cotton 8 is used to adsorb the condensate, and a liquid sealing silica gel 9 is provided above the liquid absorbing cotton 8. The liquid sealing silica gel 9 is used to hold liquids similar to e-liquid to prevent leakage, which helps to improve the user experience. The liquid absorbing cotton 8 and the liquid sealing silica gel 9 can be sequentially arranged on the upper end surface of the ventilation pipe 3, or can be sequentially embedded in the inner wall of the ventilation pipe 3 to achieve the purpose of liquid absorption and liquid holding.
[0034] The implementation principle of an electronic atomization device according to an embodiment of the present application is as follows: The liquid guiding medium 4 extends to the bottom of the liquid storage cavity 112, so that the liquid in the liquid storage cavity 112 is always in contact with the liquid guiding medium 4. Under the suction effect, the liquid in the liquid storage cavity 112 can be transported towards the upper end of the liquid guiding medium 4, so that the atomization core 5 can always atomize the liquid, without repeatedly inverting the whole electronic atomization device, thereby helping to improve the user experience and convenience of the electronic atomization device.
[0035] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
