Description

Atomizer core assembly and assembly method thereof, atomizer and atomizing device

[0001] This application claims priority to the prior application with application number 202311243091.7 filed on September 25, 2023, entitled “Atomizer core assembly and assembly method thereof, atomizer and atomization device”. The contents of the above-mentioned prior application are incorporated into this text by introduction. Technical Field

[0002] The present application relates to the field of electronic atomization technology, and in particular to an atomization core assembly and an assembly method thereof, an atomizer, and an atomization device. Background Art

[0003] Aerosol generating devices and electronic devices used to atomize non-nicotine media (such as health care drugs, therapeutic drugs, etc.) can be collectively referred to as atomizers. A nebulizer is a product that can heat the atomized liquid and atomize it into a gas. In the prior art, an atomizer generally includes a shell and an atomizer core, wherein the atomizer core includes a ceramic atomizer core and a cotton atomizer core, etc., but compared with the cotton atomizer core, the ceramic atomizer core has a poorer taste. If a cotton atomizer core is used, a stainless steel tube is often used as a bracket. The atomized liquid can only pass through the bracket from the oil guide hole of the stainless steel bracket and enter the cotton atomizer core. Too few oil guide holes will result in insufficient oil intake, affecting the taste of the atomizer. Too many oil guide holes will make the atomizer's anti-leakage performance poor. Therefore, how to improve the anti-leakage performance while ensuring the taste of the atomizer is an urgent problem to be solved.

[0043] Referring to Figures 1 to 4, the present application provides an atomizer core assembly 300, which includes: a porous support 120, an atomizer core 110, and a sealing sleeve 130. The porous support 120 has a mounting cavity 121, an outer wall 122, and micropores 126 that allow atomized liquid to penetrate from the outer wall 122 into the mounting cavity 121; the atomizer core 110 is disposed in the mounting cavity 121, and a hollow atomization channel 111 is formed therein; the sealing sleeve 130 is sleeved on the outer periphery of the porous support 120 and surrounds the atomizer core 110 therein, and a liquid inlet hole 1311 is formed through the side wall of the sealing sleeve 130.

[0045] Preferably, the sealing sleeve 130 is sleeved on the outer periphery of the porous support 120 , and the sealing sleeve 130 can be fitted on the outer periphery of the porous support 120 , which is beneficial to further improve the anti-leakage performance of the atomizer 100 .

[0046] It can be understood that in the atomizer core assembly 300 provided in the embodiment of the present application, the atomizer core 110 , the porous support 120 , and the sealing sleeve 130 are arranged in sequence from the inside to the outside.

[0047] Optionally, the sealing sleeve 130 may be, but is not limited to, a silicone member, a rubber member, etc.

[0048] In this embodiment, a liquid inlet hole 1311 is formed through the side wall of the sealing sleeve 130, and the porous bracket 120 has micropores 126 that allow the atomized liquid to penetrate from the outer wall 122 into the installation cavity 121. When the atomizer core assembly 300 is assembled to the atomizer 100, the atomized liquid 180 enters the porous bracket 120 from the liquid inlet hole 1311 of the sealing sleeve 130 and infiltrates the atomizer core 110 through the micropores 126. The atomizer core 110 heats the atomized liquid 180 and atomizes it into smoke, which then flows out of the atomizer core assembly 300 through the atomization channel 111 to deliver the atomized smoke to the target object. In addition, an embodiment of the present application provides a porous bracket 120, which is sleeved on the outer periphery of the atomizer core 110. The porous bracket 120 has a plurality of micropores 126. The plurality of micropores 126 allow the atomized liquid 180 to penetrate from the outer wall 122 into the mounting cavity 121, so that the atomized liquid 180 infiltrates the atomizer core 110 and is atomized. Compared with the solution of using a stainless steel bracket sleeved on the outer periphery of the atomizer core 110, the porous bracket 120 provided in the present application does not require an oil guide hole, which is beneficial to improving the anti-leakage performance of the porous bracket 120, and then improving the anti-leakage performance of the atomizer core assembly 300. Furthermore, the sealing sleeve 130 is sleeved on the outer periphery of the porous support 120, which helps to prevent the atomized liquid 180 from directly infiltrating the atomizing core 110 through the gap between the porous support 120 and the sealing sleeve 130, thereby improving the anti-leakage performance of the atomizer 100, and helps to improve the uniformity of the atomized liquid 180 infiltrating the atomizing core 110, improve the taste of the smoke after atomization by the atomizing core 110, and improve the user experience of the target object. The atomizer 100 provided in this application improves the anti-leakage performance of the atomizer 100 by utilizing the sealing sleeve 130, and the processing cost and assembly cost of the sealing sleeve 130 are relatively low, which helps to save the processing cost and assembly cost of the atomizer 100.

[0049] It can be understood that, in the terminology of the present application, a “target object” refers to an object that consumes the gas atomized from the atomized liquid 180 .

[0050] It can be understood that, in the terminology of this application, "plurality" means greater than or equal to two.

[0051] Please refer to Figures 5 to 7. Optionally, in some embodiments, the porous bracket 120 further has an upper end surface 123 and an inner sidewall 124 that defines the installation cavity 121. The outer sidewall 122, the upper end surface 123, and the inner sidewall 124 are connected in sequence. One end of the porous bracket 120 on which the sealing sleeve 130 is installed further has a notch 125. The notch 125 simultaneously passes through the inner sidewall 124, the upper end surface 123, and the outer sidewall 122 to connect with the installation cavity 121. The atomizer core 110 includes a liquid guide 114 and a heating element 115. The liquid guide 114 at least partially extends into the notch 125. Exemplarily, the porous support 120 is roughly cylindrical, and the mounting cavity 121 is surrounded by the side walls of the porous support 120 , and its shape is adapted to the shape of the atomizer core 110 . For example, the mounting cavity 121 can be cylindrical, and the upper end of the mounting cavity 121 is open to facilitate the loading and unloading of the atomizer core 110 . The outer wall of the atomizer core 110 fits against the inner wall of the mounting cavity 121 to better transmit the atomized liquid 180 .

[0052] The porous bracket 120 provided in the embodiment of the present application has a mounting cavity 121 and a notch 125 that passes through the inner wall 124, the upper end surface 123 and the outer wall 122. In the process of sleeve-mounting the porous bracket 120 on the periphery of the atomizer core 110, the liquid guide 114 and the heating element 115 are first stacked, wherein the heating element 115 is arranged on one side of the liquid guide 114, and the liquid guide 114 wraps the heating element 115 therein, and then the liquid guide 114 and the heating element 115 are wound, and the liquid guide 114 is further stacked. The heating element 115 is inserted into the mounting cavity 121 of the porous support 120, wherein part of the liquid guide member 114 and the heating element 115 are arranged in the mounting cavity 121, and the liquid guide member 114 protruding from the mounting cavity 121 is cut away along the surface of the outer wall 122 away from the inner wall 124, so that the liquid guide member 114 at least partially extends into the notch 125. The liquid guide member 114 arranged in the notch 125 can increase the amount of atomized liquid 180 absorbed by the liquid guide member 114, thereby improving the atomization efficiency of the atomizer core assembly 300 for the atomized liquid 180. The porous support 120 of the embodiment of the present application has the notch 125, which facilitates manual assembly of the atomizer core 110, reduces the accuracy of the action of assembling the atomizer core 110, and is conducive to improving the work efficiency of assembling the atomizer core 110.

[0053] Optionally, the liquid guiding member 114 may be oil-conducting cotton, and the liquid guiding member may be used to absorb and store the atomized liquid 180 .

[0054] Alternatively, in some embodiments, the heating element 115 is a heating net that is wound into a cylindrical heating net, and the outer circumference of the cylindrical heating net is attached to the inner circumference of the liquid guide 114. In other embodiments, the heating element 115 is a heating wire that is wound into a spiral heating wire, and the outer circumference of the spiral heating wire is attached to the inner circumference of the liquid guide 114.

[0055] Optionally, in some embodiments, the liquid guiding member 114 is a sheet-shaped body, and the sheet-shaped liquid guiding member 114 is enclosed to form the atomization channel 111, and at least one end is located in the notch 125, and the outer peripheral surface of the heating member 115 is attached to the inner peripheral surface of the liquid guiding member 114.

[0056] It can be understood that at least one end of the liquid guiding member 114 is located in the notch 125 . Alternatively, one end of the liquid guiding member 114 is located in the notch 125 , or both opposite ends of the liquid guiding member 114 are located in the notch 125 .

[0057] In this embodiment, the liquid guiding member 114 is a sheet-like body, the heating member 115 and the liquid guiding member 114 are stacked, and when the atomization channel 111 is formed inside the atomization core 110, the outer peripheral surface of the heating member 115 is attached to the inner peripheral surface of the liquid guiding member 114. In other words, the liquid guiding member 114 is arranged on the outer periphery of the heating member 115, so that when the atomized liquid 180 infiltrates into the liquid guiding member 114 through the liquid inlet hole 1311 and the micropores 126, the heating member 115 can heat and atomize the atomized liquid 180 infiltrating into the side of the liquid guiding member 114 close to the atomization channel 111, and transport the atomized smoke out of the atomization core assembly 300 through the atomization channel 111, so as to transport the atomized smoke to the target object. In which, at least one end of the liquid guiding member 114 is located in the notch 125. Compared with the solution in which the liquid guiding member 114 is only arranged in the mounting cavity 121, the portion of the liquid guiding member 114 provided in the embodiment of the present application that is arranged in the notch 125 is beneficial to increasing the amount of the liquid guiding member 114 that absorbs the atomized liquid 180, is beneficial to the heating member 115 to fully atomize the atomized liquid 180 and deliver sufficient smoke to the target object, is beneficial to improving the atomization efficiency of the atomization core assembly 300 for the atomized liquid 180, and improves the user experience of the target object.

[0058] Please refer to Figure 8. Optionally, the atomizer core 110 includes an atomizing portion 112 and a protruding portion 113. The atomizing portion 112 has the atomizing channel 111. The protruding portion 113 is protruded from the surface of the atomizing portion 112 away from the atomizing channel 111. The atomizing portion 112 passes through the mounting cavity 121, and the protruding portion 113 passes through the notch 125.

[0059] In the embodiment of the present application, in the process of sleeve-mounting the porous support 120 on the outer periphery of the atomizing core 110, the liquid guide 114 and the heating element 115 are first stacked, wherein the heating element 115 is arranged on one side of the liquid guide 114, and the liquid guide 114 wraps the heating element 115 therein, and then the liquid guide 114 and the heating element 115 are wound around the outer periphery of the rod body 200, and further the liquid guide 114 and the heating element 115 are inserted into the mounting hole of the porous support 120. The mounting cavity 121 is provided to form the atomizing portion 112; further, part of the liquid guiding member 114 is provided in the mounting cavity 121, and the liquid guiding member 114 protruding from the mounting cavity 121 is cut away along the surface of the outer wall 122 away from the inner wall 124, so that the liquid guiding member 114 passing through the mounting cavity 121 forms the protruding portion 113, and the protruding portion 113 can increase the storage capacity of the atomizing core 110 for the atomized liquid 180, so as to improve the efficiency of atomizing the atomized liquid 180.

[0060] Optionally, in some embodiments, the porous support 120 is a porous ceramic support.

[0061] In this embodiment, the porous support 120 is a porous ceramic support having a plurality of micropores 126 through which the atomized liquid 180 can penetrate from the outer wall 122 into the mounting cavity 121. The micropores 126 can be formed directly during the preparation of the porous support 120, thereby simplifying the preparation process of the porous support 120. Furthermore, compared to the solution of using a stainless steel support sleeved around the outer periphery of the atomizer core 110, the porous support 120 provided in this application does not require an oil guide hole, which helps improve the anti-leakage performance of the porous support 120, and thus improves the anti-leakage performance of the atomizer core assembly 300.

[0062] Optionally, in some embodiments, the mounting cavity 121 of the porous support 120 has an air inlet 127 on a side facing away from the notch 125, and the sealing sleeve 130 has an air outlet 1351 on a side close to the notch 125, and the air inlet 127 communicates with the air outlet 1351. In other words, the mounting cavity 121 of the porous support 120 has an air inlet 127 on a side facing away from the upper end surface 123, and the sealing sleeve 130 has an air outlet 1351 on a side close to the upper end surface 123, and the air inlet 127 communicates with the air outlet 1351.

[0063] It can be understood that the air inlet 127, the atomization channel 111 and the air outlet 1351 are connected in sequence.

[0064] In this embodiment, the air inlet 127 is used to allow air to enter the atomizer core assembly 300. When the heating element 115 heats the liquid guide element 114, the atomized liquid 180 stored in the liquid guide element 114 is atomized into smoke. The smoke and air flow to the air outlet 1351 through the atomization channel 111 and are transported out of the atomizer core assembly 300 through the air outlet 1351. The air inlet 127 and the air outlet 1351 form convection, which is beneficial to improving the transmission efficiency of the smoke formed by the atomized atomized liquid 180 in the atomizer core assembly 300 and improving the smoothness of the smoke transmission, thereby realizing the transmission of smoke to the target object, thereby improving the user experience of the target object.

[0065] Optionally, the orthographic projections of the liquid inlet hole 1311 and the notch 125 on the outer sidewall 122 do not overlap. In other words, the orthographic projection of the liquid inlet hole 1311 on the surface of the outer sidewall 122 facing away from the inner sidewall 124 is staggered with the notch 125. In other words, the liquid inlet hole 1311 and the notch 125 are staggered in the circumferential direction.

[0066] In this embodiment, the liquid inlet hole 1311 and the notch 125 are staggered, so that the atomized liquid 180 in the oil storage chamber 163 cannot directly enter the notch 125 through the liquid inlet hole 1311 of the sealing sleeve 130, thereby preventing the portion of the liquid guide 114 arranged in the notch 125 from being directly infiltrated by the atomized liquid 180, thereby facilitating improved uniformity of the infiltration of the atomizer core 110 with the atomized liquid 180, avoiding the influence of the atomization effect due to different concentrations of the atomized liquid 180 in different areas of the atomizer core 110, and facilitating improved taste of the smoke atomized by the atomizer core 110, thereby enhancing the user experience of the target user.

[0067] Please refer to Figures 9 to 11. Optionally, in some embodiments, the sealing sleeve 130 includes a columnar portion 131, a connecting portion 132 and a surrounding portion 133 connected in sequence, the columnar portion 131 and the surrounding portion 133 are spaced apart and arranged on the same side of the connecting portion 132, the surrounding portion 133 is arranged around a portion of the outer periphery of the columnar portion 131, the columnar portion 131 is sleeved on the outer periphery of the porous bracket 120, and the columnar portion 131, the connecting portion 132 and the surrounding portion 133 enclose a plug-in slot 136.

[0068] It can be understood that the surrounding portion 133 is disposed around a portion of the outer circumference of the column portion 131 , and the surrounding portion 133 can be sleeved around a portion of the outer circumference of the column portion 131 .

[0069] It can be understood that the two opposite ends of the connecting portion 132 are respectively connected to the column portion 131 and the surrounding portion 133 , and the connecting portion 132 is used to connect the column portion 131 and the surrounding portion 133 into an integrated structure.

[0070] It can be understood that in the atomizer 100 provided in the embodiment of the present application, the atomizing core 110 , the porous support 120 , the column portion 131 and the surrounding portion 133 are arranged in sequence from the inside to the outside.

[0071] In this embodiment, the column portion 131 is sleeved on the outer periphery of the porous support 120 to prevent the atomized liquid 180 from directly entering the interior of the porous support 120 through the gap between the porous support 120 and the porous support 120, thereby preventing part of the atomized liquid 180 from directly infiltrating the atomizer core 110, thereby improving the leakage-proof performance of the atomizer core assembly 300, and is conducive to improving the uniformity of the atomized liquid 180 infiltrating the atomizer core 110, improving the taste of the smoke after atomization by the atomizer core 110, and improving the user experience of the target object. In addition, the column portion 131, the connecting portion 132 and the surrounding portion 133 enclose a plug-in slot 136, and the plug-in slot 136 is plugged into an external component to achieve a sealed connection between the atomizer core assembly 300 and the external component. When the atomizer core assembly 300 is assembled to the atomizer 100, the plug-in groove 136 is used to plug the air guide tube 140. At this time, the surrounding portion 133 is sleeved on a portion of the outer periphery of the air guide tube 140, that is, part of the air guide tube 140 is sandwiched between the surrounding portion 133 and the column portion 131, further improving the sealing performance between the porous bracket 120 and the air guide tube 140, which is conducive to preventing part of the atomized liquid 180 from entering the gap on the side of the air guide tube 140 away from the upper end surface 123. The porous support 120 prevents part of the atomized liquid 180 from directly infiltrating the atomizer core 110 from the gap between the porous support 120 and the air guide tube 140, and also prevents the atomized liquid 180 from directly entering the air guide channel 1421 from the gap on the side of the air guide tube 140 close to the upper end surface 123, thereby preventing part of the atomized liquid 180 from being directly discharged from the atomizer core assembly 300 without being atomized by the atomizer core 110, thereby improving the anti-leakage performance of the atomizer core assembly 300 and enhancing the user experience of the target object.

[0072] Please refer to Figures 12 and 13. Optionally, when the atomizer core assembly 300 is assembled to the atomizer 100, the atomizer 100 includes an air guide tube 140, and the air guide tube 140 includes a first air guide portion 141 and a second air guide portion 142 connected to each other. The first air guide portion 141 is sleeved on the outer periphery of a portion of the sealing sleeve 130, and the second air guide portion 142 has an air guide channel 1421, and the air guide channel 1421 is connected to the atomization channel 111. The surrounding portion 133 is sleeved on the outer periphery of the first air guide portion 141, and the connecting portion 132 is located on the side of the first air guide portion 141 away from the second air guide portion 142.

[0073] Preferably, the first air guide portion 141 is sleeved on a portion of the outer circumference of the sealing sleeve 130 . Alternatively, the first air guide portion 141 is fitted onto a portion of the outer circumference of the sealing sleeve 130 , which is beneficial for further improving the anti-leakage performance of the atomizer core assembly 300 and the atomizer 100 .

[0074] Preferably, the column portion 131 is sleeved on the outer periphery of the porous support 120 , and the column portion 131 is fitted on the outer periphery of the porous support 120 , which is beneficial to further improve the anti-leakage performance of the atomizer 100 .

[0075] Preferably, the surrounding portion 133 is sleeved on the outer periphery of the first air guide portion 141 , and the surrounding portion 133 is fitted on the outer periphery of the first air guide portion 141 , which is beneficial to further improve the anti-leakage performance of the atomizer 100 .

[0076] In this embodiment, the atomizing channel 111 is in communication with the air guide channel 1421. When the atomized liquid 180 enters the atomizing channel 111, the atomizing core 110 heats the atomized liquid 180 and atomizes it into smoke. The atomized smoke is transported out of the atomizer 100 through the air guide channel 1421 to deliver the atomized smoke to the target object. In addition, the air guide channel 1421 is connected to the atomizing channel 111, and the air guide channel 1421 of the second air guide portion 142 is connected to the atomizing channel 111. This can prevent the atomized smoke from re-mixing with the atomized liquid 180, and can also prevent unatomized atomized liquid 180 from entering the atomizing channel 111 and / or the air guide channel 1421 from mixing with the atomized smoke. This improves the patency of transporting the heated atomized smoke from the atomized liquid 180 to the target object through the air guide channel 1421, and also improves the taste of the smoke atomized by the atomizing core 110. Furthermore, the surrounding portion 133 is sleeved on the outer periphery of the first air guide portion 141, that is, the first air guide portion 141 is sandwiched between the surrounding portion 133 and the column portion 131, further improving the sealing performance between the porous support 120 and the air guide tube 140, which is conducive to preventing part of the atomized liquid 180 from entering the porous support 120 from the gap on the side of the first air guide portion 141 away from the second air guide portion 142, thereby preventing part of the atomized liquid 180 from entering the porous support 120 from the porous support. The gap between the air guide tube 140 and the atomizer core 110 is directly infiltrated, and the atomized liquid 180 is prevented from directly entering the air guide channel 1421 from the gap on the side of the first air guide portion 141 close to the second air guide portion 142, thereby preventing part of the atomized liquid 180 from being atomized by the atomizer core 110 and being directly discharged from the electronic atomizer core 110 through the air guide channel 1421, thereby improving the anti-leakage performance of the atomizer 100 and improving the user experience of the target object.

[0077] In some embodiments, the sealing sleeve 130 further includes a first sealing portion 134, which is bent and connected to an end of the cylindrical portion 131 facing away from the surrounding portion 133. The first sealing portion 134 is located on a side of the cylindrical portion 131 close to the upper end surface 123, and the side of the first sealing portion 134 facing the upper end surface 123 abuts against the porous support 120. In other words, when the atomizing core assembly 300 is assembled to the atomizer 100, the first sealing portion 134 is located on a side of the cylindrical portion 131 close to the second air guide portion 142, and the side of the first sealing portion 134 facing away from the second air guide portion 142 abuts against the porous support 120.

[0078] It can be understood that the first sealing portion 134 is bent and connected to the end of the column portion 131 away from the surrounding portion 133. It can be that the first sealing portion 134 is bent and connected to the column portion 131, and the first sealing portion 134 is arranged farther away from the surrounding portion 133 than the column portion 131. It can also be that the first sealing portion 134 is bent and connected to the column portion 131, and the first sealing portion 134, the column portion 131 and the surrounding portion 133 are arranged in sequence from the inside to the outside.

[0079] In this embodiment, the first sealing portion 134 is located on the side of the column portion 131 close to the upper end surface 123, and the first sealing portion 134 abuts against the porous bracket 120 on the side facing the upper end surface 123. The column portion 131 and the first sealing portion 134 cooperate with each other to block the passage on the side of the porous bracket 120 close to the upper end surface 123, thereby preventing the atomized liquid 180 from directly entering the atomization channel 111 through the gap between the column portion 131 and the porous bracket 120 and the gap between the first sealing portion 134 and the porous bracket 120, thereby improving the leakage-proof performance of the atomizer 100. On the one hand, the atomized liquid 180 that penetrates from the gap between the sealing sleeve 130 and the porous support 120 is prevented from being directly output from the atomizer 100 through the air guide channel 1421 without being atomized, thereby preventing the atomized smoke from mixing with the un-atomized atomized liquid 180 and reducing the taste of the atomizer 100, thereby improving the user experience of the target object; on the other hand, the atomized liquid 180 that penetrates from the gap between the sealing sleeve 130 and the porous support 120 is prevented from dripping onto the atomizer core 110, thereby avoiding differences in the content of the atomized liquid 180 in different parts of the atomizer core 110, thereby improving the atomization effect of the atomizer core 110 on the atomized liquid 180, and then improving the taste of the smoke atomized by the atomizer core 110, thereby improving the user experience of the target object.

[0080] In some embodiments, the sealing sleeve 130 also includes a second sealing portion 135, which is connected to the end of the first sealing portion 134 facing away from the column portion 131, and the second sealing portion 135 and the column portion 131 are respectively located on the same side of the first sealing portion 134, and the side of the second sealing portion 135 facing the column portion 131 abuts against the porous bracket 120, and the second sealing portion 135 has an air outlet 1351, and the air outlet 1351 connects the atomization channel 111 and the air guide channel 1421.

[0081] It can be understood that the second sealing portion 135 is connected to one end of the first sealing portion 134 away from the column portion 131 , and the opposite ends of the first sealing portion 134 are respectively connected to the second sealing portion 135 and the column portion 131 .

[0082] It is understandable that the second sealing portion 135 and the column portion 131 are respectively located on the same side of the first sealing portion 134 , and the end of the second sealing portion 135 facing away from the first sealing portion 134 is arranged toward the atomization channel 111 .

[0083] It can be understood that the atomization channel 111 , the air outlet 1351 and the air guide channel 1421 are sequentially connected, so that the smoke atomized by the atomization core 110 can be discharged from the atomizer 100 through the air outlet 1351 and the air guide channel 1421 .

[0084] In this embodiment, the second sealing portion 135 and the column portion 131 are respectively located on the same side of the first sealing portion 134, and the end of the second sealing portion 135 facing away from the first sealing portion 134 is arranged toward the atomization channel 111, and the side of the second sealing portion 135 facing the column portion 131 abuts against the porous bracket 120, so that the second sealing portion 135 blocks the passage between the side of the porous bracket 120 facing the atomization channel 111 and the side of the second sealing portion 135 facing the column portion 131, thereby preventing the atomized liquid 180 from entering the atomization channel 111 through the gap between the second sealing portion 135 and the porous bracket 120, thereby improving the leakage-proof performance of the atomization core assembly 300. On the one hand, the atomized liquid 180 that penetrates from the gap between the sealing sleeve 130 and the porous support 120 is prevented from being directly output from the atomizer 100 through the air guide channel 1421 without being atomized, thereby preventing the atomized smoke from mixing with the un-atomized atomized liquid 180 and reducing the taste of the atomizer 100, thereby improving the user experience of the target object; on the other hand, the atomized liquid 180 that penetrates from the gap between the sealing sleeve 130 and the porous support 120 is prevented from dripping onto the atomizer core 110, thereby avoiding differences in the content of the atomized liquid 180 in different parts of the atomizer core 110, thereby improving the atomization effect of the atomizer core 110 on the atomized liquid 180, and then improving the taste of the smoke atomized by the atomizer core 110, thereby improving the user experience of the target object.

[0085] Referring to FIG. 14 , the present application further provides an assembly method of an atomizer core assembly 300 , the assembly method comprising:

[0086] S101 , providing an atomizer core 110 and a rod body 200 , and wrapping the atomizer core 110 around the outer periphery of the rod body 200 .

[0087] Specifically, the atomizer core 110 includes a liquid guide member 114 and a heating member 115, and the liquid guide member 114 is a sheet. The liquid guide member 114 and the heating member 115 are first stacked, wherein the heating member 115 is arranged on one side of the liquid guide member 114, and the liquid guide member 114 wraps the heating member 115 therein. Then, the liquid guide member 114 and the heating member 115 are wrapped around the outer periphery of the rod body 200, so that the outer peripheral surface of the heating member 115 is attached to the inner peripheral surface of the liquid guide member 114.

[0089] Specifically, the liquid guiding member 114 and the heating member 115 are inserted into the installation cavity 121 of the porous bracket 120 , and parts of the liquid guiding member 114 and the heating member 115 are disposed in the installation cavity 121 .

[0090] S103 , providing a sealing sleeve 130 , sleeve the sealing sleeve 130 onto the outer periphery of the porous support 120 , and pull out the rod 200 .

[0091] Specifically, the sealing sleeve 130 includes a column portion 131, a connecting portion 132 and a surrounding portion 133 connected in sequence, the column portion 131 and the surrounding portion 133 are spaced apart and arranged on the same side of the connecting portion 132, the surrounding portion 133 is arranged around part of the outer periphery of the column portion 131, and the column portion 131 is sleeved on the outer periphery of the porous bracket 120; the sealing sleeve 130 also includes a first sealing portion 134, the first sealing portion 134 is bent and connected to the end of the column portion 131 away from the surrounding portion 133, and the first sealing portion 134 is located on the column portion 131 near the upper end surface 123 On one side, the first sealing portion 134 faces the upper end surface 123 and abuts against the porous support 120; the sealing sleeve 130 also includes a second sealing portion 135, which is connected to the end of the first sealing portion 134 away from the column portion 131, and the second sealing portion 135 and the column portion 131 are respectively located on the same side of the first sealing portion 134, and the second sealing portion 135 faces the column portion 131 and abuts against the porous support 120 to achieve a sealed connection between the sealing sleeve 130 and the porous support 120, thereby improving the anti-leakage effect of the atomization core assembly 300.

[0092] Optionally, in some embodiments, the rod 200 is removed when the sealing sleeve 130 is sleeved around the periphery of the porous support 120. In other embodiments, the rod 200 is retained when the sealing sleeve 130 is sleeved around the periphery of the porous support 120, and when the atomizer core assembly 300 is assembled to the atomizer 100, the rod 200 is removed after the base 150 is assembled to the atomizer 100.

[0093] In the assembly method of the atomizer core assembly 300 provided in this embodiment, the porous support 120 has an installation cavity 121, which facilitates the operator to place the atomizer core 110 in the installation cavity 121. The assembly method also provides a sealing sleeve 130, which is conducive to improving the sealing connection between the sealing sleeve 130 and the porous support 120, thereby improving the anti-leakage effect of the atomizer core assembly 300. The assembly method is simple and easy for the operator to operate.

[0094] Optionally, in some embodiments, the atomizer core 110 includes a liquid guide member 114, which is a sheet-shaped body. Wrapping the atomizer core 110 around the periphery of the rod body 200 includes: winding the sheet-shaped liquid guide member 114 around the periphery of the rod body 200 so that two ends of the sheet-shaped liquid guide member 114 fit together.

[0095] In this embodiment, the liquid guide member 114 is a sheet-like structure. The liquid guide member 114 and the heater 115 are first stacked, with the heater 115 positioned on one side of the liquid guide member 114 and encased within it. The liquid guide member 114 and the heater 115 are then wrapped around the outer circumference of the rod body 200, such that the outer circumference of the heater 115 abuts the inner circumference of the liquid guide member 114. The liquid guide member 114 and the heater 115 are wrapped around the outer circumference of the rod body 200, which provides support for the wrapped structure, facilitating placement of the liquid guide member 114 and the heater 115 within the mounting cavity 121. The ends of the sheet-like liquid guide member 114 fit together, making it easier for an operator to hold and insert the atomizer core 110 into the mounting cavity 121, and also facilitating further assembly of the atomizer core 110.

[0096] Optionally, in some embodiments, the porous support 120 has a notch 125; inserting the rod body 200 wrapped with the atomizer core 110 into the installation cavity 121 includes: aligning the two ends of the liquid-guiding member 114 of the sheet with the notch 125, and installing the liquid-guiding member 114 of the sheet into the installation cavity 121; and cutting off the portion of the end of the liquid-guiding member 114 of the sheet that extends outside the notch 125.

[0097] Optionally, in some embodiments, one end of the sheet-shaped liquid guiding member 114 extends out of the notch 125, and the portion of the end of the liquid guiding member 114 extending out of the notch 125 is cut off. In other embodiments, both opposite ends of the sheet-shaped liquid guiding member 114 extend out of the notch 125, and the portion of the end of the liquid guiding member 114 extending out of the notch 125 is cut off.

[0098] In the assembly method of the atomizer core assembly 300 provided in this embodiment, the sheet-like liquid-guiding member 114 and the heating member 115 are arranged around the outer circumference of the rod body 200 and inserted into the mounting cavity 121, so that portions of the liquid-guiding member 114 and the heating member 115 are disposed within the mounting cavity 121. Furthermore, the ends of the sheet-like liquid-guiding member 114 are abutted against each other, inserted into the notch 125, and partially extend beyond the notch 125. The portion of the end of the sheet-like liquid-guiding member 114 extending beyond the notch 125 is cut away, so that the end of the liquid-guiding member 114 facing away from the mounting cavity 121 is flush with the outer wall 122, thereby preventing interference with further assembly of the porous support 120 and the sealing sleeve 130. Furthermore, the portion of the liquid-guiding member 114 located within the notch 125 enhances the oil storage capacity of the atomizer core 110 and improves the atomization efficiency of the atomizer core assembly 300 for the atomized liquid 180.

[0099] Optionally, in some embodiments, the porous support 120 is a porous ceramic support, and the porous support 120 has a plurality of micropores 126 through which the atomized liquid 180 can penetrate from the outer wall 122 into the mounting cavity 121 .

[0100] In this embodiment, the porous support 120 is a porous ceramic support having a plurality of micropores 126 through which the atomized liquid 180 can penetrate from the outer wall 122 into the mounting cavity 121. The micropores 126 can be formed directly during the preparation of the porous support 120, thereby simplifying the preparation process of the porous support 120. Furthermore, compared to the solution of using a stainless steel support sleeved around the outer periphery of the atomizer core 110, the porous support 120 provided in this application does not require an oil guide hole, which helps improve the anti-leakage performance of the porous support 120, and thus improves the anti-leakage performance of the atomizer core assembly 300.

[0101] Optionally, in the assembly method of the atomizer core assembly 300 provided in an embodiment of the present application, the side wall of the sealing sleeve 130 is provided with a penetrating liquid inlet hole 1311, and the porous bracket 120 has a notch 125. The sealing sleeve 130 is sleeved on the outer periphery of the porous bracket 120, including: the orthographic projections of the liquid inlet hole 1311 and the notch 125 on the outer side wall 122 do not overlap.

[0102] In the assembly method of the atomizer core assembly 300 provided in this embodiment, the orthographic projections of the liquid inlet hole 1311 and the notch 125 on the outer wall 122 do not overlap. In other words, the liquid inlet hole 1311 and the notch 125 are staggered, so that the atomized liquid 180 in the oil storage chamber 163 cannot directly enter the notch 125 through the liquid inlet hole 1311 of the sealing sleeve 130, thereby preventing the portion of the liquid guide member 114 arranged in the notch 125 from being directly infiltrated by the atomized liquid 180, thereby facilitating the uniformity of the infiltration of the atomizer core 110 with the atomized liquid 180, avoiding the influence of the atomization effect due to the different concentrations of the atomized liquid 180 in different areas of the atomizer core 110, and facilitating the improvement of the taste of the smoke atomized by the atomizer core 110, thereby enhancing the user experience of the target user.

[0103] Please refer to Figures 5 to 7. The present application also provides an atomizer 100. The atomizer 100 includes the atomizer core assembly 300 provided in an embodiment of the present application.

[0104] In this embodiment, the atomizer core assembly 300 has a good oil leakage prevention effect, so that when the atomizer core assembly 300 is assembled in the atomizer 100, the atomizer 100 has a good oil leakage prevention effect, and the atomization liquid 180 infiltrates the atomizer core 110 with high uniformity, which is beneficial to improving the taste of the smoke after atomization by the atomizer core 110 and enhancing the user experience of the target user.

[0105] Referring to FIG. 15 , in some embodiments, the atomizer 100 further includes a base 150 and an air duct 140. The air duct 140 is sleeved over a portion of the outer circumference of the sealing sleeve 130. The base 150 has a stepped groove 151. The sealing sleeve 130 of the atomizing core assembly 300 is at least partially located within the stepped groove 151. The sealing sleeve 130 is used to achieve a sealed connection between the base 150 and the air duct 140. In other words, the base 150 has a stepped groove 151 and an inner wall 152 defining the stepped groove 151. The surrounding portion 133 penetrates the stepped groove 151 and abuts against the inner wall 152 of the stepped groove 151.

[0106] In this embodiment, when the atomized liquid 180 enters the atomizing channel 111, the atomizing core 110 heats the atomized liquid 180 and atomizes it into smoke. The atomized smoke is transported out of the electronic atomizer 100 through the air guide channel 1421 to deliver the atomized smoke to the target object. The sealing sleeve 130 of the atomizing core assembly 300 is at least partially located in the step groove 151. The sealing sleeve 130 is used to achieve a sealed connection between the base 150 and the air guide tube 140, which can prevent the atomized liquid 180 from seeping out of the gap between the base 150 and the atomizing core assembly 300, thereby preventing the atomized liquid 180 from leaking from the gap between the base 150 and the atomizing core assembly 300, thereby preventing the atomizer 100 from leaking. This improves the anti-leakage effect of the atomizer 100 and also improves the utilization rate of the atomized liquid 180, which is beneficial to improving the user experience of the target object. Furthermore, the surrounding portion 133 is inserted into the stepped groove 151 , and the sealing sleeve 130 , the air guide tube 140 , the porous support 120 , and the atomizer core 110 are all inserted into the stepped groove 151 of the base 150 , so as to fix the sealing sleeve 130 , the air guide tube 140 , the porous support 120 , and the atomizer core 110 on the base 150 . Among them, the surrounding portion 133 is penetrated by the step groove 151 and abuts against the inner wall 152 of the step groove 151, and the opposite ends of the surrounding portion 133 respectively abut against the inner wall 152 of the step groove 151 of the base 150 and the air guide tube 140. The surface of the surrounding portion 133 facing the step groove 151 is in close contact with the inner wall 152 of the step groove 151, which can prevent the atomized liquid 180 from seeping out of the gap between the base 150 and the surrounding portion 133, thereby preventing the atomizer 100 from leaking, improving the anti-leakage effect of the atomizer 100, and also improving the utilization rate of the atomized liquid 180, which is beneficial to improving the user experience of the target object.

[0107] In some embodiments, the base 150 also has a groove 153 located on the inner wall 152 and surrounding the inner periphery of the step groove 151. The surrounding portion 133 includes a sleeve sub-portion 1331 and a protruding sub-portion 1332. The sleeve sub-portion 1331 is sleeved on the outer periphery of the first air guide portion 141. The protruding sub-portion 1332 is protruded from the sleeve sub-portion 1331 away from the surface of the first air guide portion 141 and the protruding sub-portion 1332 is arranged around the sleeve sub-portion 1331. The protruding sub-portion 1332 is located in the groove 153.

[0108] It can be understood that the sleeve sub-portion 1331 is sleeved on the outer periphery of the first air guiding portion 141 , and the sleeve sub-portion 1331 can be arranged to fit the outer periphery of the first air guiding portion 141 .

[0109] It can be understood that the protruding sub-portion 1332 is protruded from the sleeve sub-portion 1331 and is arranged away from the surface of the first air guiding portion 141 . The protruding sub-portion 1332 can be arranged farther away from the first air guiding portion 141 than the sleeve sub-portion 1331 .

[0110] It can be understood that the protruding sub-portion 1332 is arranged around the sleeve sub-portion 1331 , and the protruding sub-portion 1332 is arranged around the outer periphery of the sleeve sub-portion 1331 .

[0111] In this embodiment, the sleeve sub-portion 1331 is sleeved on the outer periphery of the first air guide portion 141 to achieve a seal between the first air guide portion 141 and the porous support 120, preventing the atomized liquid 180 from passing through the gap between the first air guide portion 141 and the surrounding portion 133 and the gap between the first air guide portion 141 and the column portion 131 and entering the porous support 120, thereby improving the anti-leakage effect of the atomizer 100. In addition, the side of the sleeve sub-portion 1331 facing away from the first air guide portion 141 abuts against the step groove 151, achieving a sealed connection between the sealing sleeve 130 and the base 150, preventing the atomized liquid 180 from seeping out of the gap between the base 150 and the surrounding portion 133, avoiding the situation where the atomizer 100 leaks, and improving the anti-leakage effect of the atomizer 100. Furthermore, the protruding sub-portion 1332 is protruding from the surface of the sleeve sub-portion 1331 away from the first air guide portion 141, and the protruding sub-portion 1332 is located in the groove 153 around the step groove 151. By embedding the protruding sub-portion 1332 in the groove 153, the sealing performance between the sealing sleeve 130 and the base 150 can be further improved, and the atomized liquid 180 can be further prevented from seeping out of the gap between the base 150 and the protruding sub-portion 1332, thereby greatly improving the leakage-proof performance of the atomizer 100.

The base 150 further includes a blocking portion 154, which is arranged on the surface of the step groove 151 facing the atomizer core assembly 300, and the vent 1604 is within the range of the blocking portion 154.

The bottom shell 1601 is disposed on one side of the base 150 and the air duct 140. When the atomizer 100 is in use, the bottom shell 1601 is disposed below the gravity of the base 150 and the air duct 140. The bottom shell 1601 has a vent 1604 for allowing air to enter the atomizer 100. When the orthographic projection of the vent 1604 on the surface of the step groove 151 facing the atomizer core assembly 300 falls within the range of the blocking portion 154, and the atomized liquid 180 is atomized by the atomizer core 110 to form smoke, part of the smoke may be re-liquefied into liquid. This part of the liquid and part of the atomized liquid 180 may drip into the blocking portion 154 through the air inlet hole 127 of the porous bracket 120. The blocking portion 154 can block this part of the liquid and part of the atomized liquid 180, preventing this part of the liquid and part of the atomized liquid 180 from directly dripping into the vent 1604 and affecting the use of the atomizer 100, which is conducive to improving the user experience of the target object.

[0115] It can be understood that the atomization channel 111, the air outlet 1351 of the second sealing portion 135 of the sealing sleeve 130, the air guide channel 1421 and the opening 162 are connected in sequence to achieve the transmission of the smoke atomized by the atomization core 110 out of the atomizer 100, so as to deliver the atomized gas to the target object.

[0116] It can be understood that the receiving chamber 161 includes the oil storage chamber 163 and a chamber for arranging the air guide tube 140 .

[0117] Optionally, the atomized liquid 180 may be, but is not limited to, e-liquid, liquid healthcare medicine, or liquid therapeutic medicine.

[0118] In this embodiment, the shell 160 and the air guide tube 140 are spaced apart and enclose the oil storage chamber 163. The oil storage chamber 163 is used to set the atomized liquid 180. The atomized liquid 180 enters the atomization channel 111 through the liquid hole 1411 of the first air guide part 141, the liquid inlet hole 1311 of the sealing sleeve 130, and the micropores of the porous bracket 120 in sequence to infiltrate the atomization core 110. The atomization core 110 heats the stored atomized liquid 180 and atomizes it into smoke. The atomized smoke is transported out of the atomizer 100 through the air outlet 1351, the air guide channel 1421 and the opening 162 to transport the atomized smoke to the target object. The oil storage chamber 163, the liquid through hole 1411, and the liquid inlet hole 1311 are connected in sequence, which is conducive to controlling the speed of the atomized liquid 180 entering the atomization channel 111 from the oil storage chamber 163, improving the uniformity of the atomized liquid 180 infiltrating the atomizer core 110, improving the taste of the smoke atomized by the atomizer core 110, and improving the user experience of the target user.

[0119] Optionally, in some embodiments, the orthographic projection of the liquid hole 1411 on the surface of the sealing sleeve 130 facing the air duct 140 falls within the range of the liquid inlet hole 1311. In other words, the diameter of the liquid hole 1411 is smaller than the diameter of the liquid inlet hole 1311.

[0120] In this embodiment, the orthographic projection of the liquid through hole 1411 on the surface of the sealing sleeve 130 facing the air guide tube 140 falls within the range of the liquid inlet hole 1311, which facilitates the atomized liquid 180 to enter the liquid inlet hole 1311 from the oil storage chamber 163 through the liquid through hole 1411, thereby preventing part of the atomized liquid 180 from seeping into the gap between the first air guide portion 141 and the sealing sleeve 130 due to the small aperture of the liquid inlet hole 1311, thereby improving the anti-leakage effect of the atomizer 100. In addition, it is also beneficial for the atomized liquid 180 to evenly enter the atomization channel 111 from the liquid through hole 1411, the liquid inlet hole 1311 and the micropores of the porous bracket 120, thereby improving the taste of the smoke after being atomized by the atomization core 110 and enhancing the user experience of the target user.

The number of the liquid through holes 1411 can be two, three, or four, etc. The number of the liquid inlet holes 1311 can be two, three, or four, etc.

[0122] In this embodiment, the number of the liquid through holes 1411 and the number of the liquid inlet holes 1311 are both multiple. The multiple liquid through holes 1411 and the multiple liquid inlet holes 1311 are conducive to accelerating the speed at which the atomized liquid 180 enters the atomization channel 111 from the oil storage chamber 163, so that the atomized liquid 180 fully infiltrates the atomization core 110, which is conducive to improving the uniformity of the atomized liquid 180 infiltrating the atomization core 110, improving the taste of the smoke after atomization by the atomization core 110, and improving the user experience of the target object.
