Description

[0002] Traditional electronic atomizers include an atomization component and a battery rod component. The atomization component includes an oil cup and a heating atomization member. The e-liquid in the oil cup flows out through an atomization chamber that communicates with the oil cup and is used to arrange the heating atomization member. The e-liquid flows into the heating atomization member by gravity for heating and atomization. To save transportation costs, before transportation, the e-liquid is pre-injected into the oil cup and sealed for transportation with the heating atomization member by setting a sealing protective film to prevent the e-liquid from contacting and oxidizing with the heating atomization member or even leaking during the transportation of the oil cup. When in use, only need to puncture the sealing protective film to make the e-liquid leak to the heating atomization member for heating and atomization. However, during transportation, due to factors such as shaking or pressure during transportation, the sealing protective film is prone to accidental puncture and oil leakage, resulting in poor sealing reliability of the atomization component during transportation and the problem of easy oil leakage.

[0035] The above atomization component, the sealing seat is located in the oil storage cavity and sleeved on the central tube. The peripheral wall of the sealing seat elastically abuts against the inner wall of the oil cup, so that the sealing seat is sealed between the inner wall of the oil cup and the central tube. In addition, the oil storage cavity and the air outlet hole are separated by the central tube, and the central tube is provided with an air guide channel communicating with the air outlet hole. Before use, such as during transportation, the plugging member is connected to the part of the insertion hole and the oil inlet hole, so that the plugging member blocks the second oil passing hole and plugs the insertion hole.

During use, the plugging member can be pulled out for use, and the e-liquid in the oil storage cavity can enter the air guide channel through the oil inlet hole, the second oil passing hole and the first oil passing hole for atomization. The plugging member is detachably connected to the part of the insertion hole and the oil inlet hole, that is, through the combined sealing action of the plugging member and the sealing seat, the oil inlet hole is not communicated with the second oil passing hole, and at the same time, the e-liquid is prevented from leaking out of the insertion hole. Compared with the traditional sealing method of the atomization component using a sealing protective film, the problem of accidental puncture of the sealing protective film and oil leakage is solved.

[0036] Please refer to Figure 1 , which is a schematic structural diagram of the atomization component 10 of an embodiment of the present application.

[0037] At the same time, refer to Figure 2 and Figure 3 , the atomization component 10 of an embodiment includes an oil cup 100, a sealing seat 200 and a plugging member 300. The oil cup 100 is provided with an air outlet hole 110, an oil storage cavity 120 and an opening groove 130, and the oil storage cavity 120 communicates with the opening groove 130. The oil cup 100 protrudes a central tube 100a in the oil storage cavity 120, and the peripheral wall of the central tube 100a surrounds the air outlet hole 110, so that the oil storage cavity 120 is separated from the air outlet hole 110. The central tube 100a is provided with a first oil passing hole 140 and an air guide channel 150 that are connected to each other, and the air guide channel 150 also communicates with the air outlet hole 110.

[0038] The sealing seat 200 is located within the oil storage cavity 120 and sleeved on the central tube 100a. The peripheral wall of the sealing seat 200 elastically abuts against the inner wall of the oil cup 100. The sealing seat 200 is provided with an oil inlet hole 210, a second oil passage hole 220, and a plug hole 230. The oil inlet hole 210 communicates with the oil storage cavity 120. The oil inlet hole 210 communicates with the second oil passage hole 220 and the plug hole 230 respectively. The second oil passage hole 220 communicates with the first oil passage hole 140, so that e-liquid can sequentially pass through the oil inlet hole 210, the second oil passage hole 220, and the first oil passage hole 140 to enter the air guiding channel 150 for heating and atomization. The plugging member 300 is detachably connected to the plug hole 230 and a part of the oil inlet hole 210 to block the second oil passage hole 220 and plug the plug hole 230. Thus, when the plugging member 300 is connected to the plug hole 230 and a part of the oil inlet hole 210, e-liquid cannot pass through the second oil passage hole 220 to enter the first oil passage hole 140 and the air guiding channel 150, and at the same time, leakage of e-liquid from the plug hole 230 is avoided, so that the e-liquid can only be stored in the oil storage cavity 120. See also Figure 4 and Figure 5 , the plugging member 300 is used to be pulled out of the plug hole 230 during use. Thus, during the use process, e-liquid can sequentially pass through the oil inlet hole 210, the second oil passage hole 220, and the first oil passage hole 140 to enter the air guiding channel 150. In this embodiment, the plugging member 300 is detachably connected to the sealing seat 200, enabling the plugging member 300 and the sealing seat 200 to be quickly disassembled and assembled. It can be understood that during use, when e-liquid needs to sequentially pass through the oil inlet hole 210, the second oil passage hole 220, and the first oil passage hole 140 to enter the air guiding channel 150, the user pulls out and removes the plugging member 300 from the sealing seat 200.

[0039] The above-mentioned atomization component 10, the sealing seat 200 is located in the oil storage cavity 120 and sleeved on the central tube 100a. The peripheral wall of the sealing seat 200 elastically abuts against the inner wall of the oil cup 100, so that the sealing seat 200 is sealed between the inner wall of the oil cup 100 and the central tube 100a. Coupled with the fact that the oil storage cavity 120 and the air outlet hole 110 are separated by the central tube 100a, and the central tube 100a is provided with an air guiding channel 150 communicating with the air outlet hole 110. Before use, such as during transportation, the plugging member 300 is connected to the plugging hole 230 and a part of the oil inlet hole 210, so that the plugging member 300 blocks the second oil passing hole 220 and plugs the plugging hole 230. In this way, under the combined action of the sealing seat 200 and the plugging member 300, the e-liquid can be reliably stored in the oil storage cavity 120 to prevent oil leakage problems and achieve reliable sealing, solving the problems of poor sealing reliability and easy oil leakage of the traditional atomization component 10 during transportation; during use, the plugging member 300 can be pulled out for use, and the e-liquid in the oil storage cavity 120 can enter the air guiding channel 150 through the oil inlet hole 210, the second oil passing hole 220 and the first oil passing hole 140 for atomization. The plugging member 300 is pluggably connected to the plugging hole 230 and a part of the oil inlet hole 210, that is, through the combined sealing action of the plugging member 300 and the sealing seat 200, the oil inlet hole 210 is not communicated with the second oil passing hole 220, and at the same time, it is avoided that the e-liquid leaks from the plugging hole 230. Compared with the traditional sealing method of the atomization component 10 using a sealing protective film, the problem of accidental puncture of the sealing protective film and oil leakage is solved.

[0040] As Figure 5 shown, in one embodiment, the oil cup 100 and the central tube 100a are of an integrally formed structure, so that the oil cup 100 and the central tube 100a are firmly connected, and at the same time, the structure of the atomization component 10 is more compact, and the number of components of the atomization component 10 is simplified. In this embodiment, the oil cup 100 and the central tube 100a are integrally injection molded. It can be understood that in other embodiments, the oil cup 100 and the central tube 100a can also be formed separately and connected together by welding or gluing.

[0041] As Figure 3 shown, in one embodiment, the oil inlet hole 210 and the plugging hole 230 are respectively opened on both sides of the sealing seat 200, so that one end of the plugging member 300 inserted into the plugging hole 230 is just on the opposite sides of the e-liquid inlet direction, which is convenient for the insertion or extraction operation of the plugging member 300, and at the same time is conducive to the one-time processing and molding of the oil inlet hole 210 and the plugging hole 230. In one embodiment, the oil inlet hole 210 is opened on the top side of the sealing seat 200, and the plugging hole 230 is opened on the bottom side of the sealing seat 200.

[0042] As Figure 3As shown, in one embodiment, the central axis of the oil inlet hole 210 coincides with the central axis of the insertion hole 230, enabling the oil inlet hole 210 and the insertion hole 230 to communicate better, so that the plugging member 300 can be quickly inserted into a part of the oil inlet hole 210 through the insertion hole 230, and at the same time enabling the plugging member 300 to better block the second oil passing hole 220 when inserted into the oil inlet hole 210. It can be understood that in other embodiments, the central axis of the oil inlet hole 210 and the central axis of the insertion hole 230 are not limited to coincidence. For example, the central axis of the oil inlet hole 210 is offset from the central axis of the insertion hole 230, that is, there is a distance between the central axis of the oil inlet hole 210 and the central axis of the insertion hole 230.

[0043] As Figure 3 shown, in one embodiment, the sealing seat 200 is a silica gel seat, making the sealing seat 200 have better elasticity, and then enabling the sealing seat 200 to elastically abut against the inner wall of the oil storage cavity 120, and at the same time enabling the sealing seat 200 to tightly sleeve on the central tube 100a. Further, an annular protrusion 202 protrudes from the peripheral wall of the sealing seat 200, and the annular protrusion 202 tightly abuts against the inner wall of the oil cup 100.

[0044] As Figure 3 shown, further, the plugging member 300 includes an integrally formed limiting portion 310 and an insertion portion 320. The diameter of the limiting portion 310 is larger than the diameter of the insertion hole 230. The insertion portion 320 is inserted into the insertion hole 230 and a part of the oil inlet hole 210, and the insertion portion 320 blocks the second oil passing hole 220, enabling the plugging member 300 to be inserted into the insertion hole 230 and a part of the oil inlet hole 210, and at the same time enabling the plugging member 300 to block the second oil passing hole 220. In this embodiment, the diameter of the insertion hole 230 is equal to the diameter of the oil inlet hole 210, and the central axis of the insertion hole 230 coincides with the central axis of the oil inlet hole 210. Since the diameter of the limiting portion 310 is larger than the diameter of the insertion hole 230, the limiting portion 310 is limited outside the insertion hole 230, avoiding the problem that the limiting portion 310 is inserted into the insertion hole 230 excessively and is difficult to pull out and disassemble.

[0045] As Figure 4 and Figure 5As shown, in one embodiment, the atomization assembly 10 further includes a bottom cover 400. The bottom cover 400 is located within the opening groove 130 and is connected to the oil cup 100. The bottom cover 400 abuts against the sealing seat 200 to position the sealing seat 200 by abutting. A part of the bottom cover 400 is inserted into the insertion hole 230 to prevent e-liquid from leaking out of the insertion hole 230. At the same time, the e-liquid can reliably enter the air guide channel 150 sequentially from the oil inlet hole 210, the second oil passing hole 220, and the first oil passing hole 140. The bottom cover 400 is provided with an air inlet hole 402 communicating with the air guide channel 150, so that the air flow outside the atomization assembly 10 can enter the air guide channel 150 through the air inlet hole 402 to realize the air intake of the atomization assembly 10. In this embodiment, the bottom cover 400 is plugged and installed within the opening groove 130, and the bottom cover 400 is plugged and inserted into the insertion hole 230. Before use, first, the end of the oil cup 100 having the opening groove 130 is turned upward. Second, the plugging member 300 is pulled out from the sealing seat 200. Finally, the bottom cover 400 is inserted into the opening groove 130 and the insertion hole 230, which is convenient and fast.

[0046] As Figure 4 and Figure 5 shown, in one embodiment, the bottom cover 400 includes a bottom cover main body 410 and a convex column portion 420. The bottom cover main body 410 is located within the opening groove 130 and is connected to the oil cup 100. The bottom cover main body 410 abuts against the sealing seat 200. The convex column portion 420 is inserted into the insertion hole 230 to block the insertion hole 230, so that the bottom cover 400 abuts against the sealing seat 200, and a part of the bottom cover 400 is inserted into the insertion hole 230. In this embodiment, the bottom cover main body 410 and the convex column portion 420 are integrally formed, so that the bottom cover main body 410 and the convex column portion 420 are firmly connected, and at the same time, the structure of the bottom cover 400 is more compact. It can be understood that in other embodiments, the bottom cover main body 410 and the convex column portion 420 can also be formed separately and connected together by welding or gluing.

[0047] Of course, the pressure of the bottom cover 400 abutting against the sealing seat 200 can be large or small. If the pressure of the bottom cover 400 abutting against the sealing seat 200 is too small, the sealing seat is likely to move relative to the central tube in the direction of mutual separation between the two or even oil leakage may occur. If the pressure of the bottom cover 400 abutting against the sealing seat 200 is too large, although it can avoid the problem that the sealing seat is likely to move relative to the central tube in the direction of mutual separation between the two or even oil leakage, the sealing seat 200 is displaced excessively relative to the central tube 100a in the direction opposite to the direction of mutual separation between the two, resulting in the problem that the first oil passing hole 140 and the second oil passing hole 220 cannot be accurately aligned, affecting the problem that the e-liquid cannot reliably enter the first oil passing hole 140 during use, that is, there is a problem of poor oil guiding effect. As Figure 4 andFigure 5 As shown, to avoid the problems of poor oil guiding effect or oil leakage, further, a limiting rib 102 is formed on the outer peripheral wall of the central tube 100a. The limiting rib 102 abuts against the side of the sealing seat 200 away from the bottom cover 400. The limiting rib 102 plays a role in limiting the sealing seat 200, avoiding the problem that the excessive pressure of the bottom cover 400 abutting against the sealing seat 200 causes the sealing seat 200 to shift relative to the central tube 100a, and even the first oil passing hole 140 and the second oil passing hole 220 cannot be accurately aligned, which affects the reliable entry of e-liquid into the first oil passing hole 140 during use. At the same time, it can avoid the problem that the sealing seat is prone to move relative to the central tube in the direction of mutual separation and even cause oil leakage.

[0048] As Figure 4 and Figure 5 As shown, in one embodiment, the sealing seat 200 is provided with a communicating mounting groove 240 and an air passing hole 250. The central tube 100a is located in the mounting groove 240 and connected to the sealing seat 200, so that the sealing seat 200 is sleeved on the central tube 100a. The air inlet hole 402 is communicated with the air guiding channel 150 through the air passing hole 250. In this embodiment, the diameter of the mounting groove 240 is larger than the diameter of the air passing hole 250, and the outer diameter of the central tube 100a is larger than the diameter of the air passing hole 250, so that the mounting groove 240 and the air passing hole 250 communicate to form a stepped hole structure, enabling the sealing seat 200 to reliably connect and limit the end of the central tube 100a. To reliably align and conduct the air guiding channel 150 and the air passing hole 250, further, the center line of the air passing hole 250 coincides with the center line of the mounting groove 240, so that the central tube 100a is installed in the mounting groove 240, and the center line of the central tube 100a coincides with the center line of the air inlet hole 402, thereby enabling the central tube 100a and the air inlet hole 402 to be reliably aligned and conducted. In this way, the air flow entering through the air inlet hole 402 can quickly enter the air guiding channel 150.

[0049] As Figure 4 and Figure 5As shown, in one embodiment, the atomizer assembly 10 also includes an atomizer 500, which is located in the air guide channel and connected to the central tube 100a. The atomizer 500 is arranged corresponding to the first oil hole 140. When in use, the smoke oil in the oil storage chamber 120 can enter the first oil hole 140 through the oil inlet hole 210 and the second oil hole 220, and contact the atomizer 500, so that the atomizer 500 heats and atomizes the smoke oil. The sealing seat 200 is also provided with a through hole 260 connected to the mounting groove 240. The atomizer 500 is connected to an external power source through the through hole 260, so that the position of the external power source of the atomizer 500 is avoided from the air inlet hole 402, which is safe and hygienic, and avoids affecting the patency of the air intake of the air inlet hole 402. At the same time, the atomizer 500 can reliably connect to the external power source for conducting electricity to heat the smoke oil. In one embodiment, an air passage 502 is opened in the center of the atomizer 500, and the air passage 502 is connected to the air guide channel 150 and the air inlet 402 respectively, so that the peripheral air flow is mixed with the atomizing gas in the air passage 502 to form an aerosol and flows out through the air guide channel 150.

[0050] like Figure 4 and Figure 5 As shown, in one embodiment, the atomizer 500 includes an atomizer body 500a and a conductive electrode 500b connected to each other. The atomizer body 500a is located in the air guide channel 150 and connected to the central tube 100a. The atomizer body 500a is arranged corresponding to the first oil hole 140, so that the atomizer body 500a is in contact with the tobacco oil passing through the first oil hole 140. The conductive electrode 500b is connected to an external power source through the penetration hole 260, so that the atomizer body 500a is electrically conductive through the conductive electrode 500b external power source, and then the atomizer body 500a is powered on and heated, so that the atomizer body 500a heats the tobacco oil and atomizes it. In this embodiment, the air passage 502 is opened in the atomizer body 500a. See also Figure 7 Further, a fixing groove 160 communicating with the air guide channel 150 is provided at the end of the central tube 100a away from the air outlet 110, and the atomizer body 500a is located in the fixing groove 160 and connected to the central tube 100a, so that the atomizer body 500a is reliably fixedly connected to the inner wall of the central tube 100a. In this embodiment, the diameter of the fixing groove 160 is larger than the diameter of the air guide channel 150, and the inner wall of the fixing groove 160 is matched with the outer wall of the atomizer body 500a, so that the atomizer body 500a is reliably limited and installed in the fixing groove 160.

[0051] like Figure 8As shown, to enable the e-liquid to quickly contact and heat the outer wall of the atomizing member body 500a through the first oil passage hole 140, the atomizing efficiency of the atomizing member body 500a is improved. Further, an oil guiding annular groove 162 is formed on the inner peripheral wall of the fixing groove 160. The oil guiding annular groove 162 is communicated with the second oil passage hole 220 and is also communicated with the first oil passage hole 140 in a butt joint manner. In this embodiment, the first oil passage hole 140 is a kidney-shaped hole. The e-liquid contacts the atomizing member body 500a through the second oil passage hole 220, the oil guiding annular groove 162 and the first oil passage hole 140, so that the contact area between the e-liquid and the atomizing member body 500a is relatively large, and the e-liquid can quickly contact and heat the outer wall of the atomizing member body 500a through the first oil passage hole 140, thereby improving the atomizing efficiency of the atomizing member body 500a. It can be understood that in other embodiments, the first oil passage hole 140 is not limited to a kidney-shaped hole, but may also be a circular hole, and the number of the first oil passage holes 140 is multiple. The multiple first oil passage holes 140 are spaced along the peripheral wall of the central tube 100a. The multiple first oil passage holes 140 are all communicated with the oil guiding annular groove 162, so that any first oil passage hole 140 can be correspondingly communicated with the second oil passage hole 220 through the oil guiding annular groove 162, and the e-liquid can quickly contact and heat the outer wall of the atomizing member body 500a through the first oil passage hole 140, thereby improving the atomizing efficiency of the atomizing member body 500a.

[0052] In one embodiment, the atomizing member body 500a includes a ceramic atomizing member and an oil absorbing cotton member. The oil absorbing cotton member is sleeved on the outer peripheral wall of the ceramic atomizing member. The ceramic atomizing member is electrically connected to the conducting electrode 500b, so that the ceramic atomizing member conducts electricity and generates heat. Thus, when the e-liquid enters through the second oil passage hole 220 and the first oil passage hole 140, it first contacts the oil absorbing cotton member. The oil absorbing cotton member quickly adsorbs and guides it to various positions on the outer peripheral wall of the ceramic atomizing member, so that the e-liquid can contact and heat the outer wall of the ceramic atomizing member more quickly through the first oil passage hole 140. Coupled with the fact that an oil guiding annular groove 162 is formed on the inner peripheral wall of the installation groove 240 and the first oil passage hole 140 is a kidney-shaped hole, the contact area between the e-liquid and the atomizing member body 500a is relatively large, and further improves the atomizing efficiency of the atomizing member body 500a. In this embodiment, the oil absorbing cotton member is a high-temperature resistant oil guiding cotton member, so that the oil absorbing cotton member has good high-temperature resistant performance.

[0053] As Figure 4 and Figure 5As shown, in one embodiment, the atomization assembly 10 further includes a conductive pressing member 600. The bottom cover 400 is provided with a connection hole 404. The conductive pressing member 600 passes through the connection hole 404, and the conductive pressing member 600 abuts against and presses the conductive electrode 500b, so that the conductive electrode 500b is positioned on the sealing seat 200 and electrically connected to the conductive pressing member 600. Furthermore, the conductive electrode 500b is externally connected to a power source through the conductive pressing member 600 to improve the reliability of the external connection of the conductive electrode 500b to the power source. In this embodiment, the conductive pressing member 600 is installed in the connection hole 404 from the side of the bottom cover 400 away from the oil cup 100, so that a part of the conductive pressing member 600 is exposed on the side of the bottom cover 400 to abut against and conduct electricity with the conductive pin of the electronic atomizer. To make the conductive pressing member 600 better abut against and press the conductive electrode 500b, also refer to Figure 6 , further, a pressing groove 206 is further provided on the side of the sealing seat 200 adjacent to the bottom cover 400. The conductive electrode 500b passes through the through hole 260, and a part of the conductive electrode 500b is received in the pressing groove 206. A part of the conductive pressing member 600 is inserted into the pressing groove 206 and abuts against the conductive electrode 500b, so that the conductive pressing member 600 better abuts against and presses the conductive electrode 500b. In this embodiment, the conductive pressing member 600 is inserted into the pressing groove 206, and the conductive pressing member 600 abuts against the conductive electrode 500b at least on the side wall of the part located inside the pressing groove 206.

[0054] As Figure 4 and Figure 5 shown, to avoid the problem that too many slot holes provided on the bottom cover 400 result in low stress intensity of the bottom cover 400, further, the connection hole 404 is provided at a position corresponding to the connection part of the bottom cover main body 410 and the convex column part 420. The pressing groove 206 is communicated with the insertion hole 230, so that when the convex column part 420 is inserted into the insertion hole 230, the conductive pressing member 600 is inserted into the pressing groove 206 and presses the conductive electrode 500b. To improve the bending resistance of the conductive pressing member 600 pressing the conductive electrode 500b and avoid the problem that the conductive pressing member 600 is prone to side bending, furthermore, a connection notch 424 is provided on the outer peripheral wall of the convex column part 420. The connection notch 424 is correspondingly communicated with the connection hole 404, and the connection notch 424 is correspondingly arranged with the pressing groove 206. The conductive pressing member 600 is inserted into the connection hole 404, and a part of the outer peripheral wall of the conductive pressing member 600 is located in the connection notch 424 and fixedly connected to the convex column part 420, improving the bending resistance of the conductive pressing member 600 pressing the conductive electrode 500b and avoiding the problem that the conductive pressing member 600 is prone to side bending.

[0055] To better press and position the conductive electrode 500b in the pressing groove 206, further, a limiting groove is provided on one side of the sealing seat 200 adjacent to the bottom cover body 410. The limiting groove extends into the pressing groove 206 and the through hole 260 respectively. After the conductive electrode 500b passes through the through hole 260, it is sequentially positioned in the limiting groove and the pressing groove 206, so that the conductive electrode 500b is better received and positioned on the sealing seat 200, and further the conductive electrode 500b is better pressed and positioned in the pressing groove 206.

[0056] This application also provides an electronic atomizer, including the atomization component 10 described in any of the above embodiments.

[0057] Compared with the prior art, the present invention has at least the following advantages:

[0058] 1. The sealing seat 200 is located in the oil storage cavity 120 and sleeved on the central tube 100a. The peripheral wall of the sealing seat 200 elastically abuts against the inner wall of the oil cup 100, so that the sealing seat 200 seals between the inner wall of the oil cup 100 and the central tube 100a. In addition, the oil storage cavity 120 and the air outlet hole 110 are separated by the central tube 100a, and the central tube 100a is provided with an air guiding channel 150 communicating with the air outlet hole 110. Before use, such as during transportation, the plugging member 300 is connected to the insertion hole 230 and a part of the oil inlet hole 210, so that the plugging member 300 blocks the second oil passing hole 220 and plugs the insertion hole 230. In this way, under the combined action of the sealing seat 200 and the plugging member 300, the e-liquid is reliably stored in the oil storage cavity 120 to prevent oil leakage, realizing reliable sealing and solving the problems of poor sealing reliability and easy oil leakage of the traditional atomization component 10 during transportation; during use, the plugging member 300 can be pulled out for use, and the e-liquid in the oil storage cavity 120 can enter the air guiding channel 150 through the oil inlet hole 210, the second oil passing hole 220 and the first oil passing hole 140 for atomization;

[0059] 2. For the above atomization component 10, the plugging member 300 is detachably connected to the insertion hole 230 and a part of the oil inlet hole 210, that is, through the combined sealing action of the plugging member 300 and the sealing seat 200, the oil inlet hole 210 is not communicated with the second oil passing hole 220, and at the same time, it is avoided that the e-liquid leaks from the insertion hole 230. Compared with the traditional sealing method of the atomization component 10 using a sealing protective film, the problem that the sealing protective film is easily accidentally punctured and causes oil leakage is solved.

[0060] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
