Description

Technical Field

[0001] This disclosure relates to the technical field of atomizing devices, and in particular to an atomizing structure with silicone oil-gas separation and an electronic atomizing device. Background Technology

[0002] Electronic atomizers have an oil inlet channel and an airflow channel. The separators used to separate the oil and airflow channels inside electronic atomizers are mostly made of hard plastic, metal, or simple sealing rings.

[0003] When the separator is used for a long time, subjected to temperature changes, or mechanical stress, oil can easily leak from the oil circuit to the air circuit, or air can enter the oil circuit from the air circuit, causing oil leakage in the electronic atomizer. Oil leakage not only contaminates the internal parts of the device and the user interface, but also leads to oil waste, uneven atomization, and even the risk of short circuits.

[0004] For example, in the prior art document CN201822212552.5, an electronic cigarette includes an atomizing component and an oil tank. The ceramic core is secured by a second silicone pad and electrode protrusions, allowing for interference-forced contact, resulting in simple assembly, lower and more stable contact resistance. The first silicone pad, upper bracket, and lower bracket are packaged together, with tapered funnels added to the oil holes on both sides of the upper bracket. However, in this design, the oil holes on the first silicone pad are prone to leakage along the plane of the first silicone pad. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a silicone oil-gas separation atomization structure and electronic atomization device with better leak-proof performance.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A silica gel oil-gas separation atomizing structure includes an atomizing element, a first housing, a silica gel separator, and a second housing. The silica gel separator is sandwiched between the first housing and the second housing. An oil storage groove is formed between the first housing and the silica gel separator. The atomizing element is disposed in the oil storage groove and sandwiched between the first housing and the silica gel separator.

[0008] The silicone separator includes an air inlet and an oil inlet. The air inlet has an air inlet channel that is connected to the atomizing element. The oil inlet has an oil inlet protrusion on the side opposite to the first housing. The oil inlet protrusion and the air inlet form a stepped structure. The oil inlet protrusion has a first oil inlet hole that is connected to the oil storage tank. The second housing has an oil inlet column that has a second oil inlet hole. The oil inlet column is embedded in the first oil inlet hole, and the second oil inlet hole is connected to the first oil inlet hole.

[0009] In one embodiment, the silicone separator has an arc groove at one end opposite to the second housing, and the atomizing element is disposed in the arc groove.

[0010] In one embodiment, a first annular sealing strip is also provided inside the first oil inlet hole, and the first annular sealing strip abuts against the outer wall of the oil inlet column.

[0011] In one embodiment, the silicone separator is further provided with a second annular sealing strip in the circumferential direction, and the second annular sealing strip abuts against the inner wall of the second housing.

[0012] In one embodiment, the first housing has a first annular connecting portion and a housing insert groove. The silicone separator has a silicone annular connecting portion and a silicone insert groove formed on its edge. The first annular connecting portion is correspondingly installed in the silicone insert groove, and the silicone annular connecting portion is correspondingly installed in the housing insert groove.

[0013] In one embodiment, the atomizing structure for separating the silicone oil and gas path further includes oil-absorbing cotton, and a receiving groove is formed between the silicone separator and the second housing, with the oil-absorbing cotton installed in the receiving groove.

[0014] In one embodiment, the second housing is further provided with a fixing protrusion, and the oil-absorbing cotton is provided with a fixing hole, through which the fixing protrusion passes.

[0015] In one embodiment, a limiting groove is formed on the side of the silicone separator facing away from the second housing, and a portion of the atomizing element is installed in the limiting groove.

[0016] In one embodiment, the silicone separator has a fixing groove on the side opposite to the first housing, and the second housing has a protruding fixing member, a portion of which is embedded in the fixing groove.

[0017] An electronic atomizing device includes the atomizing structure with silicone oil-gas separation as described in any of the above embodiments.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] The aforementioned silicone oil-gas separation atomization structure features an oil inlet column embedded in a first oil inlet hole. The inner wall of the first oil inlet hole tightly wraps around the outer wall of the oil inlet column, forming a radial seal. The contact surface between the oil inlet boss and the second housing forms an end-face seal under pressure, thereby improving the connection sealing of the oil inlet channel and effectively preventing oil leakage from the interface. The stepped structure formed by the oil inlet boss and the air inlet raises the connection plane between the oil inlet and the air inlet, increasing the difficulty and resistance of the lateral flow from the oil inlet channel to the air inlet channel, thus improving leak-proof performance. The silicone separator integrates the features of the air inlet channel, oil inlet boss, first oil inlet hole, and the stepped structure, reducing the use of independent sealing rings or complex hard separators, simplifying the overall structure, and making the silicone oil-gas separation atomization structure compact.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 2 As shown, this is an embodiment of the atomizing structure 10 with silicone oil-gas separation according to this disclosure, including an atomizing element 100, a first housing 200, a silicone separator 300 and a second housing 400. The silicone separator 300 is sandwiched between the first housing 200 and the second housing 400. An oil storage tank 201 is formed between the first housing 200 and the silicone separator 300. The atomizing element 100 is disposed in the oil storage tank 201 and sandwiched between the first housing 200 and the silicone separator 300.

[0030] Furthermore, the silicone separator 300 includes an air inlet 310 and an oil inlet 320. The air inlet 310 has an air inlet channel 3101, which is connected to the atomizing element 100. The oil inlet 320 has an oil inlet boss 321 protruding on the side opposite to the first housing 200. The oil inlet boss 321 and the air inlet 310 form a stepped structure. The oil inlet boss 321 has a first oil inlet hole 3201, which is connected to the oil storage tank 201. The second housing 400 has an oil inlet column 410 protruding. The oil inlet column 410 has a second oil inlet hole 4101. The oil inlet column 410 is embedded in the first oil inlet hole 3201. The second oil inlet hole 4101 is connected to the first oil inlet hole 3201 to form an oil inlet channel.

[0031] In this embodiment, the atomizing element 100 is used to atomize the oil. The first housing 200 and the silicone separator 300 together form an oil storage tank 201 and fix the atomizing element 100. The silicone separator 300 forms a stepped air inlet 310 and an oil inlet 320. The oil inlet 320 protrudes to form an oil inlet boss 321, making the oil passage higher than the air passage, thus achieving physical isolation. The air inlet channel 3101 directly connects to the atomizing element 100 to deliver air, and the oil inlet of the second housing 400... The column 410 is embedded in the first oil inlet hole 3201 of the silicone separator 300, so that the oil inlet column 410 is sealed against the inner wall of the first oil inlet hole 3201. The oil inlet part 320 has an oil inlet channel, and the air inlet part 310 has an air inlet channel 3101, so that the silicone separator 300 separates the oil inlet channel and the air inlet channel 3101. The oil inlet column 410 is embedded in the first oil inlet hole 3201, so that the second housing 400 and the silicone separator 300 are sealed together.

[0032] In the aforementioned silicone oil-gas separation atomizing structure 10, the oil inlet column 410 is embedded in the first oil inlet hole 3201. The inner wall of the first oil inlet hole 3201 tightly wraps the outer wall of the oil inlet column 410 to form a radial seal. The contact surface between the end face of the oil inlet boss 321 and the second housing 400 forms an end face seal under pressure, thereby improving the connection sealing performance of the oil inlet channel and effectively preventing oil leakage from the interface. The stepped structure formed by the oil inlet boss 321 and the air inlet 310 raises the connection plane between the oil inlet 320 and the air inlet 310, increasing the difficulty and resistance of the lateral flow from the oil inlet channel to the air inlet channel 3101, thereby improving the leak-proof performance. The silicone separator 300 integrates the features of the air inlet channel 3101, the oil inlet boss 321, the first oil inlet hole 3201, and the stepped structure, reducing the use of independent sealing rings or complex hard separators, simplifying the overall structure, and making the silicone oil-gas separation atomizing structure 10 compact.

[0033] like Figure 2 As shown, in one embodiment, the silicone separator 300 has an arcuate groove 301 at one end facing away from the second housing 400, and the atomizing element 100 is disposed within the arcuate groove 301. In this embodiment, the edge of the arcuate groove 301 abuts against the inner wall of the first housing 200, allowing oil to flow smoothly from the inner wall of the first housing 200 into the arcuate groove 301, preventing oil leakage from the gap between the first housing 200 and the silicone separator 300. The arcuate groove 301 then guides the oil to contact the atomizing element 100, enabling the oil to be smoothly atomized.

[0034] like Figure 1As shown, in one embodiment, a first annular sealing strip 322 is further protruding inside the first oil inlet hole 3201, and the first annular sealing strip 322 abuts against the outer wall of the oil inlet column 410. In this embodiment, the abutment of the first annular sealing strip 322 against the outer wall of the oil inlet column 410 increases the sealing area at the oil inlet channel, prevents oil leakage, maintains a good sealing effect, and ensures that the oil does not leak into other components or the external environment.

[0035] like Figure 1 As shown, in one embodiment, the silicone separator 300 is further provided with a second annular sealing strip 330 protruding circumferentially, the second annular sealing strip 330 abutting against the inner wall of the second housing 400. In this embodiment, the abutment of the second annular sealing strip 330 against the inner wall of the second housing 400 seals the silicone separator 300 against the second housing 400 and limits and fixes the silicone separator 300 to the second housing 400, preventing it from shifting due to vibration or external force, and ensuring precise alignment of the air intake channel 3101 and the oil intake channel.

[0036] like Figure 1 and Figure 3 As shown, in one embodiment, the first housing 200 has a protruding first annular connecting portion 210 and a housing embedding groove 202. The silicone separator 300 has a silicone annular connecting portion 340 formed on its edge and a silicone embedding groove 302. The first annular connecting portion 210 is correspondingly installed in the silicone embedding groove 302, and the silicone annular connecting portion 340 is correspondingly installed in the housing embedding groove 202. In this embodiment, the first annular connecting portion 210 of the first housing 200 is embedded in the silicone embedding groove 302 of the silicone separator 300. The elastic deformation of the silicone separator 300 achieves a tight fit. The silicone annular connecting portion 340 of the silicone separator 300 is embedded in the housing embedding groove 202 of the first housing 200, further enhancing the sealing performance at the connection. The cooperation between the first housing 200 and the silicone separator 300 forms a multi-level sealing barrier, significantly improving the sealing reliability between the first housing 200 and the silicone separator 300.

[0037] like Figure 3 As shown, in one embodiment, the atomizing structure 10 with silicone oil-gas separation further includes an oil-absorbing cotton 500. A receiving groove 401 is formed between the silicone separator 300 and the second housing 400, and the oil-absorbing cotton 500 is installed in the receiving groove 401. In this embodiment, the oil-absorbing cotton 500 can quickly absorb excess oil, preventing residual oil from flowing into the air passage or leaking to the outside. The turbulence noise generated when the oil flows can be absorbed by the porous structure of the oil-absorbing cotton 500, significantly reducing the operating noise of the atomizing structure.

[0038] like Figure 3 As shown, in one embodiment, the second housing 400 further has a fixing protrusion 430, and the oil-absorbing cotton 500 has a fixing hole 501, through which the fixing protrusion 430 passes. In this embodiment, by the fixing protrusion 311 passing through the fixing hole 501, the displacement of the oil-absorbing cotton 500 along the axial direction of the air inlet 310 is restricted, preventing the oil-absorbing cotton 500 from loosening due to airflow.

[0039] like Figure 4 As shown, in one embodiment, the silicone separator 300 has a limiting groove 303 on the side opposite to the second housing 400, and a portion of the atomizing element 100 is installed in the limiting groove 303. In this embodiment, a portion of the atomizing element 100 is embedded in the limiting groove 303, thereby limiting and fixing the silicone separator 300 of the atomizing element 100; when dropped or subjected to mechanical impact, the silicone separator 300 can absorb the impact force, and by elastically wrapping the portion of the atomizing element 100 with the silicone separator 300, the impact resistance of the atomizing element 100 is improved.

[0040] like Figure 1 and Figure 3 As shown, in one embodiment, the silicone spacer 300 has a fixing groove 304 on the side opposite to the first housing 200, and the second housing 400 has a protruding fixing member 420, a portion of which is embedded in the fixing groove 304. In this embodiment, by partially embedding the fixing member 420 in the fixing groove 304, lateral displacement or rotation between the silicone spacer 300 and the second housing 400 is suppressed, and the second housing 400 and the silicone spacer 300 form an assembly guide, reducing assembly errors between the second housing 400 and the silicone spacer 300.

[0041] This application also provides an electronic atomizing device, including the silicone oil-gas separation atomizing structure 10 described in any of the above embodiments. In this embodiment, the silicone oil-gas separation atomizing structure 10 prevents oil from flowing between the air inlet channel 3101 and the oil inlet channel, thereby improving the leak-proof performance of the electronic atomizing device.

[0042] Compared with the prior art, this disclosure has at least the following advantages:

[0043] In the aforementioned silicone oil-gas separation atomizing structure 10, the oil inlet column 410 is embedded in the first oil inlet hole 3201. The inner wall of the first oil inlet hole 3201 tightly wraps the outer wall of the oil inlet column 410 to form a radial seal. The contact surface between the end face of the oil inlet boss 321 and the second housing 400 forms an end face seal under pressure, thereby improving the connection sealing performance of the oil inlet channel and effectively preventing oil leakage from the interface. The stepped structure formed by the oil inlet boss 321 and the air inlet 310 raises the connection plane between the oil inlet 320 and the air inlet 310, increasing the difficulty and resistance of the lateral flow from the oil inlet channel to the air inlet channel 3101, thereby improving the leak-proof performance. The silicone separator 300 integrates the features of the air inlet channel 3101, the oil inlet boss 321, the first oil inlet hole 3201, and the stepped structure, reducing the use of independent sealing rings or complex hard separators, simplifying the overall structure, and making the silicone oil-gas separation atomizing structure 10 compact.

[0044] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
