Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to an electronic atomization structure and an electronic atomization device. Background Technology

[0002] To improve the sealing effect between the liquid-conducting ceramic and the liquid storage chamber, sealing silicone is often wrapped around the liquid-conducting ceramic to reduce leakage from the liquid storage chamber. For example, the utility model patent application with application number CN202022544336.8 shows that the atomizing silicone is sleeved on the ceramic atomizer and installed in the atomizer chamber, which effectively reduces the leakage problem. However, because the atomizing silicone effectively seals the liquid storage chamber, after the liquid-conducting ceramic is fully wetted by the atomizing liquid, it can easily aggravate the problem of pressure imbalance inside and outside the liquid storage chamber, thereby affecting the liquid-conducting efficiency of the liquid-conducting ceramic.

[0030] This application provides an electronic atomization structure. The electronic atomization structure includes an atomizing shell, sealing silicone, a liquid-conducting ceramic, a heating element, and a microporous liquid-separating component. The atomizing shell has an atomizing chamber and a liquid storage tank. The atomizing chamber is connected to the liquid storage tank through a liquid outlet. The liquid-conducting ceramic is housed within the atomizing chamber and sealed at the liquid outlet. The heating element is connected to the liquid-conducting ceramic and is at least partially exposed within the atomizing chamber.

[0031] The aforementioned electronic atomization structure, with its sealing silicone surrounding the liquid outlet and sandwiched between the atomizing shell and the liquid-guiding ceramic, effectively improves the sealing effect at the connection between the atomizing shell and the liquid-guiding ceramic.

This, in turn, further improves the pressure balance within the liquid storage chamber while ensuring the sealing effect of the atomized liquid in the electronic atomization structure, thus significantly improving the liquid guiding efficiency of the liquid-guiding ceramic.

[0032] To better understand the electronic atomization structure of this application, the following further explanation is provided:

[0033] Please refer to the following: Figures 1 to 4One embodiment of the electronic atomizing structure 10 includes an atomizing shell 100, a sealing silicone 200, a liquid-conducting ceramic 300, a heating element (not shown), and a microporous liquid separator 500. The atomizing shell 100 has an atomizing chamber 101 and a liquid storage chamber 102. The atomizing chamber 101 is connected to the liquid storage chamber 102 through a liquid outlet 103. The liquid-conducting ceramic 300 is housed in the atomizing chamber 101 and sealed at the liquid outlet 103. The heating element is connected to the liquid-conducting ceramic 300 and is at least partially exposed in the atomizing chamber 101. The sealing silicone 200 is disposed around the liquid outlet 103 and sandwiched between the atomizing shell 100 and the liquid-conducting ceramic 300. The atomizing shell 100 is also provided with a pressure balance port 104, which is connected to the liquid storage chamber 102 and the atomizing chamber 101 respectively.

The microporous liquid separator 500 is sealed at the pressure balance port 104 and is connected to both the pressure balance port 104 and the pressure balance hole 201 respectively.

[0034] The aforementioned electronic atomization structure 10 allows the sealing silicone 200 to surround the liquid outlet 103 and be sandwiched between the atomizing shell 100 and the liquid-guiding ceramic 300, effectively improving the sealing effect at the connection between the atomizing shell 100 and the liquid-guiding ceramic 300. This, combined with the air pressure balance port 104 connecting to the liquid storage chamber 102 and the atomizing chamber 101 respectively, and the air pressure balance hole 201 of the sealing silicone 200 connecting to the air pressure balance port 104, and the microporous liquid separator 500 sealing the air pressure balance port 104, and the microporous liquid separator 500 connecting to the air pressure balance port... The pressure balance port 104 is connected to the pressure balance port 201, that is, the pressure balance port 104 is added to achieve the pressure balance of the liquid storage chamber 102. The microporous liquid separator 500 is sealed at the pressure balance port 104. While preventing the leakage of the atomized liquid at the pressure balance port 104, the gas exchange in the liquid storage chamber 102 is effectively achieved. In this way, while ensuring the sealing effect of the atomized liquid of the electronic atomization structure 10, the pressure balance in the liquid storage chamber 102 is further improved, and the liquid guiding efficiency of the liquid guiding ceramic 300 is improved.

[0035] Please refer to the following: Figures 1 to 4 In one embodiment, the microporous liquid barrier 500 is a metal liquid barrier with a plurality of gas flow micropores 501.

Further, the pore size of each gas flow micropore 501 is 0.1 μm to 10 μm. Further, the porosity of the microporous liquid barrier 500 corresponding to the pressure balance port 104 is 60% to 85%. Further, the thickness of the microporous liquid barrier 500 is 0.1 mm to 0.3 mm, further ensuring the structural strength of the microporous liquid barrier 500, and ensuring effective gas exchange to balance the gas pressure inside and outside the liquid storage chamber 102 while ensuring effective blocking of the atomized liquid to reduce leakage.

Further, there are multiple pressure balancing holes 201, each communicating with both the pressure balancing port 104 and the microporous liquid separator 500. Further, the distance between any two adjacent pressure balancing holes 201 is greater than the diameter of any single pressure balancing hole 201, thus better ensuring effective gas exchange to balance the pressure inside and outside the liquid storage tank 102.

[0038] Please refer to the following: Figures 1 to 4 In one embodiment, the liquid storage chamber 102 is provided with a liquid storage cotton 600, which is connected to the liquid guiding ceramic 300. The liquid storage cotton 600 is also spaced apart from the microporous liquid separator 500, which reduces the contact of the atomized liquid at the microporous liquid separator 500 and further reduces leakage.

[0039] Please refer to the following: Figures 1 to 4 In one embodiment, the end of the liquid-conducting ceramic 300 is sealed at the liquid outlet 103, and the sealing silicone 200 is sleeved on the peripheral wall of the liquid-conducting ceramic 300 and the end wall near the liquid outlet 103, with the sealing silicone 200 and the liquid outlet 103 being positioned separately.

Further, the sidewall portion of the liquid-conducting ceramic 300 is spaced apart from the cavity wall of the atomizing chamber 101. Further, the heating element is located at the end of the liquid-conducting ceramic 300 away from the liquid outlet 103 and is at least partially exposed in the atomizing chamber 101, which facilitates the stable conduction of the atomized liquid in the storage tank 102 to the liquid-conducting ceramic 300 under gravity.
