[0060] In existing heat-not-burn electronic cigarette devices, the assembly of the filter structure is not only cumbersome, inefficient, and easy to loosen, but also makes the structure not compact enough and occupies a large space.

[0061] Based on this, the present application proposes a filter tip structure and an assembly method thereof to solve the problems of complex structure and assembly of existing filter tips.

[0062] Please refer to Figures 1 to 12 In one aspect, the present invention provides a filter structure for use in an electronic smoking device, comprising:

[0063] The filter cover 10 protrudes downward to form a frame 11, the frame 11 is used to form an oil storage chamber 111, and the filter cover 10 protrudes downward to form a first side wall 12;

[0064] The filter lower cover assembly 20 includes a filter lower cover 21, the upper portion of which has a filter mounting groove 211, and the first side wall 12 is assembled and connected to the filter mounting groove 211; the filter lower cover 21 is provided with a third through hole 22, and the frame 11 is passed through the third through hole 22 and abuts against the hole wall of the third through hole 22.

[0065] In the present application, the filter upper cover 10 downwardly protrudes to form a frame body 11, which is used to form an oil storage cavity 111 for storing essential oil. The frame body 11 formed by the downward protrusion of the filter upper cover 10 makes the formed oil storage cavity 111 integral with the filter upper cover 10, thereby reducing the assembly steps and helping to ensure the stability of the structure. The filter upper cover 10 downwardly protrudes with a first side wall 12, and the upper part of the filter lower cover 21 has a filter mounting groove 211. The first side wall 12 is assembled and connected with the filter mounting groove 211. At the same time, the filter lower cover 21 is provided with a third through hole 22, and the frame body 11 is arranged in the third through hole 22 and abuts with the hole wall of the third through hole 22. In implementation, the frame body 11 passes through the third through hole 22 to realize positioning during assembly, and then the first side wall 12 is inserted into the filter mounting groove 211, so that the assembly process between the filter upper cover 10 and the filter lower cover assembly 20 is simple and has few steps, thereby simplifying the assembly steps, providing assembly efficiency, and further providing product production efficiency, and ensuring the stable, firm and non-loose connection between the two, realizing the mutual connection and limiting of the filter upper cover 10, the oil storage cavity 111 and the filter lower cover assembly 20, and ensuring the structural stability of the filter structure. Further, the filter structure can be simplified, and the filter upper cover 10 and the frame body 11 are integrally formed. The downwardly formed frame body 11 facilitates the accommodation of the oil storage cavity 111 into the main machine, and the oil storage cavity 111 can be set longer. The space of the oil storage cavity 111 is expanded to facilitate the setting of a larger oil storage cavity 111 in a limited space.

[0066] In some embodiments, the frame body 11 and the first side wall 12 are respectively located at both ends of the bottom surface of the filter upper cover 10, so as to cover more positions of the bottom surface of the filter upper cover 10, realize the connection of the filter upper cover 10 and the filter lower cover assembly 20 at more positions, and enhance the stability of the connection. It can be understood that the outer wall profile of the first side wall 12 matches the groove wall profile of the filter mounting groove 211, and the outer wall profile of the frame body 11 matches the hole wall profile of the third through hole 22, so as to help improve the stability of the connection between the filter upper cover 10 and the filter lower cover assembly 20.

[0067] Exemplarily, the filter upper cover is made of PCTG material, black and semi-transparent, and is injection molded. The filter lower cover 21 is injection molded and made of PC2805, which is transparent as a whole.

[0068] In some embodiments, in order to enhance the connection strength of the filter upper cover 10 and the filter lower cover 21, the first side wall 12 and the filter mounting groove 211 are connected through the filter clasp 121 and the filter clasp groove 214, and the stable connection of the filter upper cover 10 and the filter lower cover 21 is achieved through the assembly connection between the filter clasp 121 and the filter clasp groove 214. For example, in a preferred embodiment, the filter clasp 121 is arranged on the outer side wall of the first side wall 12 of the filter upper cover 10, the filter clasp groove 214 is arranged on the groove wall of the filter mounting groove 211 of the filter lower cover 21, and the connection strength of the filter upper cover 10 and the filter lower cover 21 can be enhanced through the cooperation of the filter clasp 121 and the filter clasp groove 214. The assembly connection of the filter clasp 121 and the filter clasp groove 214 is simple and reliable, which helps to improve the filter assembly efficiency and improve the stability of the filter structure.

[0069] In some preferred embodiments, the filter structure further comprises an atomization device 30, the atomization device 30 is located at the bottom of the inner wall of the frame body 11 and forms an oil storage cavity 111 with the frame body 11, the top of the atomization device 30 is provided with an oil inlet hole 32 in communication with the oil storage cavity 111 for introducing essential oil into the atomization device 30; the side wall of the frame body 11 is provided with a second outlet 112, and the atomization device 30 has an atomization outlet 31 in communication with the second outlet 112. By arranging the atomization device 30 at the bottom of the inner wall of the frame body 11, the atomization upper cover of the atomization device 30 and the inner wall of the frame body 11 together form the oil storage cavity 111, the oil storage cavity 111 has good sealing performance, and being placed in the frame body 11 also helps to reduce the space and can avoid unnecessary contact with other components to collide with the atomization device 30 and damage the sealing performance of the oil storage cavity 111.

[0070] In some embodiments, the side wall of the frame body 11 is provided with an air inlet 113, and the atomization device 30 has an atomization inlet 39 in communication with the air inlet 113. The essential oil can slowly penetrate into the atomization cavity of the atomization device 30 through the oil inlet hole 32, the external air enters through the air inlet 113 and the atomization inlet 39, the essential oil is heated and atomized in the atomization device 30, and the atomized essential oil forms atomized gas with the air and exits through the atomization outlet 31 and the second outlet 112.

[0071] In some embodiments, the atomization device 30 comprises an atomization upper cover 33, an atomization lower cover 34, a cotton core 35, a heating wire 36, an atomization oil absorption cotton 37, and an electrode 38. The atomization upper cover 33 and the atomization lower cover 34 are buckled to each other and form a chamber structure, which is an atomization chamber of the atomization device 30. An atomization inlet 39 and an atomization outlet 31 are respectively located on two sides of the atomization device 30. For example, the atomization upper cover 33 and the atomization lower cover 34 are respectively provided with through holes or through grooves to form the atomization inlet 39 and the atomization outlet 31 when the atomization upper cover 33 and the atomization lower cover 34 are assembled to each other. An oil inlet hole 32 is opened at the top of the atomization upper cover 33. The atomization oil absorption cotton 37 is located in the inner cavity of the atomization lower cover 34 and is used to absorb oil or water vapor. The bottom of the atomization lower cover 34 is provided with an electrode mounting hole 313 which is in communication with the inner cavity of the atomization lower cover 34. The cotton core 35 is sleeved into the spiral heating wire 36 and is arranged in the inner cavity of the atomization lower cover 34 together. The end of the heating wire 36 extends into the electrode mounting hole 313 at the bottom of the atomization lower cover 34. The electrode 38 is pressed into the electrode mounting hole 313 at the bottom of the atomization lower cover 34 and abuts against the end of the heating wire 36. The electrode 38 is electrically connected with an electronic module (not shown) of the main machine. The atomization device is controlled to work through the electronic module of the main machine. When working, the essential oil in the oil storage cavity enters the atomization chamber from the oil inlet hole 32 and permeates onto the cotton core. The heating wire 36 is controlled to heat by the electronic module of the main machine to realize essential oil atomization.

[0072] Preferably, the atomization upper cover 33 is injection molded and is made of food-grade silica gel with a material color of 60 degrees. The atomization lower cover 34 is injection molded and is made of PC2805. The cotton core 35 is made of organic cotton. The heating wire 36 is made of nickel-chromium alloy wire. The atomization oil absorption cotton 37 is needle cotton.

[0073] In some embodiments, the outer periphery of the atomization device is provided with a convex ring which is tightly attached to the inner wall of the frame body 11 to prevent essential oil leakage. In some preferred embodiments, the convex ring is a top convex ring 310 and a bottom convex ring 311. The top convex ring 310 is located at the top outer periphery of the atomization upper cover 33. The bottom convex ring 311 is located at the bottom outer periphery of the atomization upper cover 33. The air inlet 113 and the atomization inlet 39, and the atomization outlet 31 and the second outlet 112 are all located between the top convex ring 310 and the bottom convex ring 311. The top convex ring 310 and the bottom convex ring 311 prevent essential oil and atomization gas from leaking between the atomization device 30 and the inner wall of the frame body 11, thereby preventing leakage.

[0074] In some embodiments, the bottom outer periphery of the atomization lower cover 34 has a boss 312 with a size greater than the bottom inner wall of the frame body 11, so that when the atomization device 30 is installed in the frame body 11, the boss 312 abuts against the bottom end of the frame body 11 to prevent the atomization device 30 from entering the inside of the frame body 11 too much, causing the air inlet 113 and the atomization inlet 39, and the atomization outlet 31 and the second outlet 112, etc. to be misaligned and communicate, causing gas or essential oil to leak.

[0075] In some embodiments, the filter lower cover 21 is provided with a smoke output channel 23 and a gas transmission structure mounting groove 24 beside the smoke output channel 23, and the smoke output channel 23 is located below the filter mounting groove 211.

[0076] The filter lower cover assembly 20 further comprises a filter air channel support 25, which comprises a smoke output channel cover plate 251 and a gas transmission structure 252.

[0077] The filter air channel support 25 is covered on the filter lower cover 21, the smoke output channel cover plate 251 is located at the bottom of the filter mounting groove 211 and abuts against the top of the smoke output channel 23; the gas transmission structure 252 is mounted in the gas transmission structure mounting groove 24, the gas transmission structure 252 is provided with a first outlet 253 and a second inlet 254 which are in communication with each other, the smoke output channel 23 is provided with a first inlet 231 which is in communication with the first outlet 253, and the second inlet 254 is in communication with the second outlet 112. The bottom of the gas transmission structure mounting groove 24 is provided with a second through hole 241, the gas transmission structure 252 is further provided with a third outlet 258 which is in communication with the second inlet 254, the third outlet 258 is in communication with the second through hole 241, and the second through hole 241 is in communication with the air channel of the main machine provided with a differential pressure sensor. Exemplarily, the filter air channel support 25 is made of PC2805 material, is transparent as a whole, and is injection molded. Compared with forming the gas transmission structure 252 by multiple parts which is easy to produce gaps, the gas transmission structure 252 is manufactured by an integral molding processing method, has higher sealing performance, and has simple manufacturing process, convenient processing, and convenient assembly with the filter lower cover 21. The smoke generated by the cigarette heating enters the smoke output channel 23 through the through hole at the bottom of the filter lower cover 21, the atomized gas after the essential oil is atomized enters the second inlet 254 through the second outlet 112, then enters the first inlet 231 from the first outlet 253, and finally enters the smoke output channel 23 to mix with the smoke, circulates and cools in the smoke output channel 23, then enters the channel of the filter upper cover 10 and goes out of the channel for smoking, i.e. goes out of the filter for smoking.

[0078] In some embodiments, the smoke output channel cover 251 is provided with a first delivery pipe 255 upwardly. A smoke outlet 2510 is provided at a corresponding position on the smoke output channel cover 251 for downward communication with the smoke output channel 23. The filter cover 10 is provided with a second delivery pipe 13 downwardly communicating with the outside. A filter silicone mounting groove 256 is provided at the mouth of the first delivery pipe 255. The filter silicone mounting groove 256 is filled with filter silicone 257. The second delivery pipe 13 is inserted into the filter silicone mounting groove 256 and sealed by the filter silicone 257, thereby connecting the second delivery pipe 13 to the first delivery pipe 255. At this point, the mixture of smoke and atomized gas entering the smoke output channel 23 can enter the second delivery pipe 13 through the first delivery pipe 255 and then exit through the channel of the filter cover 10. A first delivery pipe 255 and a second delivery pipe 13 are provided. By plugging the first delivery pipe 255 and the second delivery pipe 13 into each other, the connection strength between the filter upper cover 10 and the filter lower cover 21 can be enhanced to prevent the filter upper cover 10 and the filter lower cover 21 from loosening.

[0079] In some embodiments, the smoke output channel 23 includes an air intake column 232 and an arc-shaped channel 233. The interior of the air intake column 232 is an air intake channel. The bottom of the air intake channel penetrates the bottom of the lower filter cover 21 to allow smoke to enter, and the top is connected to the channel entrance of the arc-shaped channel 233. The arc-shaped channel 233 is arranged around the outer periphery of the air intake column 232. The above-mentioned enclosure can be a complete enclosure or even multiple circles of enclosure, or it can be a partial enclosure. For example, the arc-shaped channel 233 can be in the form of half a circle, one circle, or multiple circles. For example, when one or more circles of the arc-shaped channel 233 are arranged around the outer periphery of the air intake column 232, it is preferably arranged on the outer semicircle of the air intake column 232. In a preferred embodiment, the first inlet 231 is positioned at the front or middle of the arcuate channel 233 so that atomized gas enters the arcuate channel 233 from the front or middle and mixes with the smoke. The channel outlet of the arcuate channel 233 is connected to the bottom end of the first delivery pipe 255 on the smoke output channel cover 251, so that the mixture of smoke and atomized gas mixes and cools within the arcuate channel 233 before entering the second delivery pipe 13 of the filter cover 10 through the first delivery pipe 255 and exiting. The horizontally distributed arcuate channels 233 are not the traditional vertically stacked channel distribution form. The annular contact area is large, and the curved channels that can be formed have long bends, eliminating the need for excessive bends. This ensures a cooling effect while not affecting the smoke circulation speed, allowing the smoke to be discharged as quickly as possible, ensuring the speed and quality of smoke output.

[0080] In some embodiments, the smoke output channel 23 is filled with oil-absorbing cotton 234, which absorbs condensate from smoke or atomized gas. The oil-absorbing cotton 234 does not completely fill its area, leaving a path for smoke or atomized gas to circulate. For example, the oil-absorbing cotton 234 may fill all or part of the bottom of the curved channel 233 of the smoke output channel 23, leaving space at the top of the curved channel 233 for smoke or atomized gas to circulate. The oil-absorbing cotton 234 filling the curved channel 233 is a single unit, ensuring a unified arrangement of the oil-absorbing cotton 234. This facilitates placement and replacement, and helps stabilize the oil-absorbing cotton 234 within the smoke output channel 23, preventing it from accidentally shifting, such as toward the smoke output channel cover 251. In a preferred embodiment, the smoke output channel cover 251 includes a downwardly facing abutment post that abuts against the top of the oil-absorbing cotton 234 to retain the oil-absorbing cotton 234. Exemplarily, the channel oil-absorbing cotton 234 is needle cotton.

[0081] In some embodiments, a magnet mounting groove is recessed on the bottom surface of the filter lower cover 21, and a magnet 213 is provided in the magnet mounting groove for cooperating with the magnet on the main unit of the electronic smoking device.

[0084] The assembly method comprises the following steps:

[0085] Pre-assemble the filter cover 10 and the filter cover assembly 20;

[0086] Place the filter cover 10 on the filter lower cover assembly 20, and insert the frame 11 on the filter cover 10 into the third through hole 22 on the filter lower cover assembly 20 so that the outer wall of the frame 11 abuts against the hole wall of the third through hole 22;

[0087] When the frame 11 is inserted into the third through hole 22 , the first side wall 12 is aligned with the filter installation groove 211 and inserted into the filter installation groove 211 to achieve assembly of the filter structure.

[0088] In the present application, the frame body 11 formed by the downward protrusion of the filter upper cover 10 is integrated with the filter upper cover 10 to form the oil storage cavity 111, thereby reducing the assembly steps and helping to ensure the stability of the structure. When assembling the filter upper cover 10 and the filter lower cover 21, the filter lower cover 21 is provided with a third through hole 22, the frame body 11 is arranged in the third through hole 22 and abuts against the hole wall of the third through hole 22 to realize the positioning function through the frame body 11 and the third through hole 22. The filter upper cover 10 is provided with a first side wall 12, and the upper part of the filter lower cover 21 is provided with a filter mounting groove 211. The first side wall 12 is assembled and connected with the filter mounting groove 211. In the implementation, the frame body 11 is arranged through the third through hole 22 to realize the positioning during assembly, and then the first side wall 12 is inserted into the filter mounting groove 211. The assembly process between the filter upper cover 10 and the filter lower cover assembly 20 is simple and has few steps, thereby simplifying the assembly steps, providing assembly efficiency, further providing product production efficiency, and ensuring the stable, firm and non-loose connection between the two, realizing the mutual connection and positioning of the filter upper cover 10, the oil storage cavity 111 and the filter lower cover assembly 20, and ensuring the structural stability of the filter structure.

[0089] In some embodiments, the filter structure comprises an atomization device 30. The specific structure of the atomization device 30 is described above. In the assembly of the atomization device 30, the filter upper cover 10 is inverted, the bottom of the inner wall of the frame body 11 faces upward, and the essential oil is injected into the frame body 11. After the atomization device 30 is assembled as a whole, it is installed at the bottom of the inner wall of the frame body 11 to form the oil storage cavity 111 with the frame body 11, and the second outlet 112 is in communication with the atomization outlet 31 after installation. The atomization device 30 is assembled first, and then the frame body 11 is sealed and the oil storage cavity 111 is formed. Compared with the form of sealing the oil cavity first and then assembling the atomization device, it helps to reduce the consequences of oil leakage caused by the loosening of the sealing caused by the atomization device assembly process, thereby improving the sealing performance of the oil storage cavity 111.

[0090] In some embodiments, the assembly of the atomization device 30 comprises the following steps:

[0091] The atomization oil absorption cotton 37 is assembled into the inner cavity of the atomization lower cover 34, and the bottom of the atomization lower cover 34 is provided with an electrode mounting hole 313 in communication with the inner cavity of the atomization lower cover 34;

[0092] The cotton core 35 is sleeved into the spiral heating wire 36 and assembled into the inner cavity of the atomization upper cover 33. At this time, the end of the heating wire 36 extends into the electrode mounting hole 313 at the bottom of the atomization lower cover 34;

[0093] The electrode 38 is pressed into the electrode mounting hole 313 at the bottom of the atomization lower cover 34 and abuts against the end of the heating wire 36;

[0094] The atomizing upper cover 33 is placed on the atomizing lower cover 34 , and the atomizing upper cover 33 and the atomizing lower cover 34 are interference fit.

[0095] Through the above-mentioned assembly steps of the atomizing device 30 , the atomizing device 30 can be assembled quickly and easily, with fewer assembly steps and good sealing performance of the atomizing device 30 .

[0096] In some embodiments, during the assembly of the heating wire 36, after the end of the heating wire 36 is inserted into the electrode mounting hole 313 at the bottom of the atomizer lower cover 34, the end of the heating wire 36 is first bent, and then the electrode 38 is pressed into the electrode mounting hole 313 at the bottom of the atomizer lower cover 34 so as to press the bent end of the heating wire 36 through the electrode 38. Considering that the end of the heating wire 36 needs to contact with the electrode 38 and achieve electrical conductivity, after the end of the heating wire 36 is inserted into the electrode mounting hole 313 at the bottom of the atomizer lower cover 34, the end of the heating wire 36 is first bent, and then the electrode 38 is pressed into the electrode mounting hole 313 at the bottom of the atomizer lower cover 34 so as to press the bent end of the heating wire 36 through the electrode 38. In this way, better contact between the end of the heating wire 36 and the electrode 38 can be achieved. At the same time, the end of the heating wire 36 enters the electrode mounting hole 313 and then bends, thereby forming a bent structure at the end. At this time, the bent end structure can form a restrictive effect, so that the end of the heating wire 36 extending into the electrode mounting hole 313 can no longer be retracted into the inside of the atomizer lower cover 34, so that the end of the heating wire 36 can remain in the electrode mounting hole 313, on the one hand, maintaining contact with the electrode 38, and on the other hand, the electrode 38 can press the bent end of the heating wire 36 to keep the position of the heating wire 36 unchanged, preventing the heating wire 36 and the cotton core 35 from shifting and affecting the assembly and atomization effect.
