Description

Technical Field

[0001] This application relates to the technical field of preparation methods for oil storage components of atomizing devices, and in particular to preparation methods and oil storage components for atomizing devices. Background Technology

[0002] Existing electronic cigarettes mainly consist of two parts: a battery and an atomizing device. The battery includes a battery that provides the operating voltage for the electronic cigarette. The atomizing device has a built-in e-liquid storage assembly, which includes an e-liquid cup and an atomizer coil inside the cup. The e-liquid cup also contains e-liquid storage cotton or other e-liquid media. The e-liquid storage assembly is usually assembled by placing the e-liquid storage cotton over the atomizer coil, and then inserting the e-liquid storage cotton and the atomizer coil together into the e-liquid cup. The e-liquid filling needle is inserted into the e-liquid storage cotton from the top, and after filling, the e-liquid filling needle is removed and the e-liquid cup is sealed.

[0003] In traditional technology, the e-liquid storage component is filled by inserting an e-liquid needle into the top of the e-liquid storage cotton. The e-liquid is unevenly distributed in the e-liquid storage cotton, and areas with high e-liquid storage rates will have the risk of leakage. Summary of the Invention

[0004] Based on this, a method for injecting oil into an oil storage medium, an oil injection fixture, a method for preparing an oil storage component, and an atomizing device are provided to improve the uniformity of the distribution of e-liquid in the oil storage medium and reduce the risk of oil leakage.

[0005] An embodiment of the first aspect of this application provides a method for injecting oil into an oil storage medium, comprising:

[0006] The oil storage medium is vented;

[0007] Inject oil into the oil storage medium used for exhaust treatment;

[0008] Obtain the oil storage unit.

[0009] According to the e-liquid injection method of the e-liquid storage medium in this application embodiment, the e-liquid storage medium is vented, and the gas inside the e-liquid storage medium is discharged. On the one hand, reducing the gas content in the e-liquid storage medium helps to improve the e-liquid absorption capacity of the e-liquid storage medium, similar to a siphon effect. During e-liquid injection, the e-liquid enters the e-liquid storage medium under the combined driving force of the injection force and the absorption force of the e-liquid storage medium, and the e-liquid will be distributed more evenly, improving the uniformity of e-liquid distribution within the e-liquid storage medium and avoiding the risk of leakage caused by high e-liquid storage rate in a certain area of ​​the e-liquid storage medium. On the other hand, reducing the gas in the e-liquid storage medium also reduces the amount of air bubbles in the e-liquid injected into the e-liquid storage medium, reducing the risk of leakage caused by the expansion of air bubbles compressing the e-liquid.

[0010] In one embodiment, the oil storage medium is configured as an oil storage cotton, and during the venting process of the oil storage medium, a preliminary compression is provided to the oil storage medium.

[0011] In one embodiment, during the preceding compression, a force is provided to drive the outer wall of the oil storage medium to contract inward into the oil storage medium.

[0012] In one embodiment, during the preceding extrusion, an extrusion chamber is provided, the size of which is smaller than the size of the oil storage medium, and the oil storage medium enters the extrusion chamber.

[0013] In one embodiment, when the oil storage medium is injected, continuous compression is provided to the oil storage medium, and the compression force of the continuous compression is less than the compression force of the preceding compression.

[0014] In one embodiment, the squeezing force of the continuous compression gradually decreases as the oil absorption rate of the oil storage medium increases.

[0015] In one embodiment, the oil storage medium is injected with oil in multiple stages, and the injection speed and / or injection volume of each stage are controlled independently.

[0016] In one embodiment, the multiple oil injection stages are distinguished according to different oil injection locations; or

[0017] The multiple oil injection stages are distinguished based on the timing of the oil injection.

[0018] In one embodiment, the oil storage medium is configured as an oil storage material strip. After the oil storage material strip is filled with oil, it is cut off to obtain the oil storage component.

[0019] In one embodiment, the oil storage material strip is subjected to micro-pressure treatment after being injected with oil and before being cut off to obtain a micro-pressure oil storage material strip.

[0020] In one embodiment, after the end of the oil-filled raw material strip is inserted into the oil cup, the raw material strip outside the oil cup is cut off to obtain the oil storage component.

[0021] An embodiment of the second aspect of this application provides an oil injection fixture for oil injection using the oil storage medium injection method as described in any of the above embodiments. The oil injection fixture is sequentially provided with:

[0022] The oil storage medium is fed into the feeding area;

[0023] The oil storage medium is vented in the venting area;

[0024] The oil injection area is where the oil storage medium is injected to form an oil storage component;

[0025] The oil storage unit discharges oil in the discharge area.

[0026] In one embodiment, the exhaust area is provided with a compression chamber, the size of which is smaller than the size of the oil storage medium, and the compression chamber compresses the oil storage medium.

[0027] In one embodiment, the oil injection area is provided with a first position oil injection stage and a second position oil injection stage in sequence along the moving direction of the oil storage medium, and the oil injection speed and oil injection volume of the first position oil injection stage and the second position oil injection stage can be independently controlled.

[0028] According to the e-liquid filling fixture of this application embodiment, the venting area vents the e-liquid storage medium, expelling the gas within the storage medium. On one hand, reducing the gas content in the storage medium helps improve its absorption capacity, similar to a siphon effect. When e-liquid is injected in the filling area, the e-liquid enters the storage medium under the combined driving force of the injection force and the absorption force of the storage medium, resulting in a more uniform distribution of the e-liquid and improving the uniformity of e-liquid distribution within the storage medium. This avoids the risk of leakage caused by a high e-liquid storage rate in a certain area of ​​the storage medium. On the other hand, reducing the gas content in the storage medium also reduces the amount of air bubbles in the injected e-liquid, minimizing the risk of leakage caused by the expansion and compression of the e-liquid by the air bubbles.

[0029] The third aspect of this application provides a method for preparing an oil storage component, wherein the oil storage component is prepared by the oil storage medium injection method as described in any of the above embodiments.

[0030] Insert the atomizing core and the oil reservoir into the oil cup.

[0031] The method for preparing an oil storage component according to the embodiments of this application prepares an oil storage component. Compared with the traditional method of injecting oil into the oil cup, the oil storage component of this application completes the oil injection work outside the oil cup. It is not limited by the oil cup for the direction and position of oil injection, which improves the uniformity of the distribution of e-liquid in the oil storage medium and reduces the risk of oil leakage of the oil storage component.

[0032] In one embodiment, the oil storage component is inserted into the oil cup, and then the atomizing core is inserted into the oil storage component inside the oil cup.

[0033] In one embodiment, the oil cup includes a cup body, a top cover, and a bottom cover, and the atomizing core is mounted on the bottom cover;

[0034] The atomizing core and the bottom cap are assembled together with the cup body, the bottom cap covers the cup body, and the atomizing core is inserted into the oil storage component;

[0035] The top cover closes the cup body.

[0036] An embodiment of the fourth aspect of this application provides an atomizing device, including an oil storage component prepared using the oil storage component preparation method described in any of the above embodiments.

[0037] The aforementioned atomizing device improves the uniformity of e-liquid distribution within the oil storage medium, reduces the risk of oil leakage, and enhances the atomization effect. Attached Figure Description

[0058] See Figure 1 , Figure 1 A schematic flowchart of an oil storage medium injection method according to an embodiment of this application is shown. In some embodiments, embodiments of this application provide an oil storage medium injection method, including:

[0059] Step S120: Vent the oil storage medium.

[0060] Step S130: Inject oil into the oil storage medium for the exhaust treatment.

[0061] Step S160: Obtain the oil storage unit.

[0062] According to the e-liquid filling method of the e-liquid storage medium described in the above embodiments of this application, the e-liquid storage medium is vented, and the gas inside the e-liquid storage medium is discharged. On the one hand, reducing the gas content in the e-liquid storage medium helps to improve the e-liquid absorption capacity of the e-liquid storage medium, similar to a siphon effect. During e-liquid filling, the e-liquid enters the e-liquid storage medium under the combined driving force of the filling force and the absorption force of the e-liquid storage medium, resulting in a more uniform distribution of e-liquid within the e-liquid storage medium. This improves the uniformity of e-liquid distribution within the e-liquid storage medium and avoids the risk of leakage caused by a high e-liquid storage rate in a certain area of ​​the e-liquid storage medium. On the other hand, reducing the gas content in the e-liquid storage medium also reduces the amount of air bubbles in the e-liquid injected into the e-liquid storage medium, reducing the risk of leakage caused by the expansion and compression of e-liquid by air bubbles.

[0063] Understandably, venting can be achieved by absorbing gas from the oil storage medium through negative pressure or by squeezing the oil storage medium to expel the gas. Venting simply needs to remove the gas from the oil storage medium.

[0064] In some embodiments, the oil storage medium is configured as oil-storing cotton, and during the venting process, a preliminary compression is applied to the oil storage medium. The oil-storing cotton possesses good oil storage, oil conductivity, and fire resistance, and contains oil-storing gaps. It is understood that the oil storage medium can also be configured as other porous structures with oil-storing gaps that can be compressed. When the oil storage medium is configured as oil-storing cotton, venting is achieved through compression. During compression, the oil-storing gaps within the cotton decrease, and the air within these gaps is expelled, thus providing preliminary compression to the oil storage medium.

[0065] In some embodiments, during the initial extrusion, a force is provided that drives the outer wall of the oil reservoir to contract inward. Extruding the oil reservoir is possible as long as a force capable of contracting it is provided; applying force from the outer wall of the oil reservoir is easier to operate than applying force from the inside outward or from the ends inward.

[0066] In some embodiments, during the preceding extrusion, an extrusion chamber is provided, the size of which is smaller than the size of the oil storage medium, and the oil storage medium enters the extrusion chamber. As the oil storage medium enters the extrusion chamber, because the size of the extrusion chamber is smaller than the size of the oil storage medium, the outer wall of the oil storage medium is compressed by the inner wall of the extrusion chamber, reducing the volume of the oil storage medium entering the extrusion chamber and achieving venting.

[0067] In some embodiments, during e-liquid filling, the e-liquid storage medium is subjected to continuous compression, with the compression force being less than that of the preceding compression. Because the e-liquid storage cotton is resilient, providing a slightly weaker continuous compression force during filling further ensures the air release effect of the e-liquid storage medium, reduces the amount of air bubbles in the injected e-liquid, and simultaneously provides storage space for the e-liquid.

[0068] In some embodiments, the squeezing force of the continuous compression gradually decreases as the oil absorption rate of the e-liquid storage medium increases. An increase in the oil absorption rate indicates a gradual increase in the amount of e-liquid within the storage medium. As the amount of e-liquid increases, the squeezing force of the continuous compression gradually decreases, gradually releasing storage space to allow e-liquid to enter. This ensures smooth e-liquid injection while reducing the amount of air bubbles in the injected e-liquid, further improving the uniformity of e-liquid distribution within the storage medium and reducing the risk of leakage.

[0069] In some embodiments, the filling of the oil storage medium includes multiple filling stages, and the filling speed and / or filling amount of each stage are independently controlled. Dividing the filling stage into multiple stages can improve the precision and controllability of the filling operation. By adjusting the filling speed and / or filling amount of each stage, the filling state of the oil storage medium can be adjusted, further improving the uniformity of the e-liquid distribution within the oil storage medium.

[0070] In some embodiments, multiple e-liquid filling stages are distinguished based on the filling location. Specifically, the e-liquid storage medium can be divided into a first-position filling stage at the center and a second-position filling stage at the edge, depending on the filling location. The first-position filling stage involves a larger filling volume, allowing the e-liquid to spread evenly from the center of the storage medium outwards. The second-position filling stage involves a smaller filling volume, replenishing a small amount of e-liquid at the edge of the storage medium to further improve the uniformity of e-liquid distribution and prevent leakage.

[0071] In some embodiments, multiple e-liquid filling stages may be distinguished based on the timing of the filling. Specifically, the filling stages can be divided according to the different times of filling. For example, the first half of the time is the first filling stage, and the second half of the time is the second filling stage. During the first filling stage, a large amount of e-liquid is injected quickly into the e-liquid storage medium, improving efficiency and allowing the e-liquid storage medium to quickly reach a certain absorption rate. Then, during the second filling stage, a smaller amount of e-liquid is injected, matching the gradually decreasing absorption capacity of the storage medium. This further improves the uniformity of e-liquid distribution while avoiding the risk of leakage.

[0072] In some embodiments, the oil storage medium is configured as an oil storage material strip. After the oil storage material strip is filled with oil, it is cut to obtain an oil storage unit. Directly filling the oil storage material strip with oil, and then cutting the strip after it has reached a certain oil absorption rate, significantly improves production efficiency compared to first cutting it into individual oil storage media and then filling them individually. This method also helps improve the consistency of oil storage units in the same batch, thereby improving product consistency.

[0073] See Figure 2 , Figure 2 A schematic flowchart of an oil-filling method for an oil storage medium according to another embodiment of this application is shown. In some embodiments, after oil filling and before cutting, the oil storage material strip is subjected to micro-pressure treatment to obtain a micro-pressurized oil storage material strip. Micro-pressure treatment can squeeze out excess e-liquid from the oil storage material strip after filling, and at the same time facilitates cutting, avoiding the oil storage material strip being too soft and affecting the cutting accuracy.

[0074] In some embodiments, an oil storage medium injection method includes:

[0075] Step S110: Configure the oil storage medium as an oil storage raw material bar.

[0076] Step S120: Exhaust the oil storage material bar.

[0077] Step S130: Inject oil into the oil storage material bar after the exhaust treatment.

[0078] Step S140: Perform micro-pressure treatment on the oil storage raw material strip to obtain micro-pressure oil storage raw material strip.

[0079] Step S150: Cut the micro-pressure oil storage raw material strip.

[0080] Step S160: Obtain the oil storage unit.

[0081] Specifically, oil storage material strips are selected as the oil storage medium. Then, the oil storage material strips are vented, oil is injected into the vented strips, and micro-pressure treatment is applied to obtain micro-pressured oil storage material strips. These micro-pressured strips are then processed to obtain oil storage components. Micro-pressure refers to a pressure slightly greater than the pressure experienced by the oil storage component during use within the oil cup, but less than the compressive force experienced during venting.

[0082] In some embodiments, after the end of the oil-filled raw material strip is inserted into the oil cup, the portion of the raw material strip outside the oil cup is cut off to obtain the oil storage component. Thus, the end of the raw material strip is already inserted into the oil cup; after cutting it off, the portion of the raw material strip outside the oil cup, i.e., the oil storage component, is then pushed into the oil cup. This process is more compact and improves the assembly efficiency of the oil storage component entering the oil cup.

[0083] See Figure 3 , Figure 3 A schematic flowchart of an embodiment of the present application for the preparation of an oil storage component is shown. In some embodiments, embodiments of the present application provide a method for preparing an oil storage component, comprising:

[0084] Step S100: Prepare an oil storage component using the oil storage medium injection method as described in any of the above embodiments.

[0085] Step S200: Install the atomizer core and oil reservoir into the oil cup.

[0086] The method for preparing an oil storage component according to the above embodiments of this application prepares an oil storage component. Compared with the traditional method of injecting oil into the oil cup, the oil storage component of this application completes the oil injection work outside the oil cup. It is not limited by the oil cup for the direction and position of oil injection, which improves the uniformity of the distribution of e-liquid in the oil storage medium, reduces the risk of oil leakage of the oil storage component, and improves the preparation efficiency.

[0087] See Figure 4 , Figure 4 This illustration shows a flowchart of a method for preparing an oil storage assembly according to an embodiment of this application, in which an atomizing device and an oil storage component are loaded into an oil cup. In some embodiments, step S200 specifically includes:

[0088] Step S210: Insert the oil reservoir into the oil cup.

[0089] Step S220: Insert the atomizing coil into the oil reservoir inside the oil cup. This method allows for a convenient and quick installation of the atomizing device and oil reservoir into the oil cup, improving preparation efficiency.

[0090] See Figure 5 , Figure 5 This illustration shows a flowchart of a method for preparing an oil storage assembly according to an embodiment of this application, in which an atomizing core is inserted into an oil storage component within an oil cup. In some embodiments, the oil cup includes a cup body, a top cap, and a bottom cap. Step S220 specifically includes:

[0091] Step S221: The atomizing core is assembled on the bottom cover.

[0092] Step S222: Assemble the assembled atomizer core and bottom cap together with the cup body, close the bottom cap to the cup body, and insert the atomizer core into the oil reservoir.

[0093] Step S223: Close the top cover to the cup body.

[0094] In some embodiments, both the bottom and top covers are made of silicone, which achieves a seal with the cup body through deformation and snap-fit ​​structures, providing good sealing and repeated disassembly performance.

[0095] See Figures 6 to 9 , Figure 6 A schematic diagram of the structure of the oil storage component is shown in the method for preparing an oil storage component according to an embodiment of this application. Figure 7 This diagram illustrates the structure of the oil storage component preparation method according to an embodiment of the present application, where the atomizing core 4 is assembled on the bottom cover 32. Figure 8 This diagram illustrates the structure of an oil storage component preparation method according to an embodiment of this application, where the assembled atomizing core 4 and bottom cover 32 are assembled together with the cup body 31. Figure 9 This diagram illustrates a method for preparing an oil storage assembly according to an embodiment of this application, where the top cover 33 is placed over the cup body 31. In some embodiments, the oil storage assembly is prepared using the method described in the above embodiment.

[0096] See Figure 6In some embodiments, the oil storage medium is configured as oil-storing cotton 2. Embodiments of this application provide an oil injection fixture 1. The venting, oil injection, and cutting processes of the oil-storing cotton 2 are all performed within the oil injection fixture 1. The oil injection fixture 1, along the feeding direction indicated by the arrow, can be sequentially divided into: a feeding area 11, a venting area 12, an oil injection area 13, and a discharge area. In some embodiments, a micro-pressure area 14 is provided between the oil injection area 13 and the discharge area. In some embodiments, the discharge area is configured as a discharge cutting-off area 15, capable of cutting off. The oil-storing cotton 2 is passed through the oil injection fixture 1, sequentially passing through the aforementioned areas, and after oil injection, is placed into the oil cup 3.

[0097] Specifically, in some embodiments, the oil storage medium enters the oil injection fixture 1 from the feeding area 11 along the feeding direction, and the end after passing through the oil injection fixture 1 is inserted into the oil cup 3. The feeding direction is also the direction of movement of the oil storage cotton 2. The inner wall cross-section of the end of the feeding area 11 is larger than the cross-section of the oil storage cotton 2, facilitating the feeding of the oil storage cotton 2. The inner wall of the feeding area 11 gradually contracts along the feeding direction until it connects with the inner wall of the extrusion chamber 121 of the exhaust area 12. The size of the extrusion chamber 121 is smaller than the size of the oil storage cotton 2, and the cross-section of the extrusion chamber 121 is smaller than the original cross-section of the oil storage cotton 2. After entering the exhaust area 12, the volume of the oil storage cotton 2 decreases, and the gas inside the oil storage cotton 2 is squeezed out, performing a preliminary compression on the oil storage cotton 2 to achieve the exhaust effect.

[0098] After venting, the oil reservoir 2 reaches the oil injection area 13. Within the oil injection area 13, depending on the injection position, a first-position oil injection stage 16 and a second-position oil injection stage 17 are set up. Multiple oil injection needles are arranged circumferentially in both the first-position and second-position oil injection stages 16 and 17. The first-position oil injection stage 16 is located just as the oil reservoir 2 enters the oil injection area 13, and the second-position oil injection stage 17 is located just before the oil reservoir 2 leaves the oil injection area 13. The injection speed and volume of the first-position and second-position oil injection stages 16 and 17 can be independently controlled. The injection speed and volume of the oil injection needles within each stage can be adjusted separately. The cross-section of the filling fixture 1 in the filling area 13 gradually expands, which means that it provides continuous compression to the oil storage cotton 2 during filling. However, the continuous compression force is less than the previous compression force. As the oil absorption rate of the oil storage medium increases, the continuous compression force gradually decreases. The oil storage cotton 2 starts to expand and absorb oil from the compressed state. The oil storage cotton 2 passing through this area is all soaked in e-liquid. By controlling parameters such as the filling speed of the front and rear filling needles or the size of the filling holes, it is ensured that the e-liquid distribution inside the oil storage cotton 2 is uniform and the oil storage rate inside the oil storage cotton 2 is adjusted.

[0099] After being filled with oil, the oil-retaining cotton 2 passes through the micro-pressure zone 14 and then enters the discharge cutting zone 15, where it is cut by the cutting blade 18. This zone is located at the outlet of the oil filling fixture 1. After exiting the discharge port, the oil-retaining cotton 2 enters the oil cup 3 and is cut by the cutting blade 18 after a certain length. The oil storage component is then placed into the oil cup 3.

[0100] Subsequent fabrication steps for the oil storage assembly:

[0101] See Figure 7 Step S221: The atomizing core 4 is assembled on the bottom cover 32.

[0102] See Figure 8 Step S222: Assemble the assembled atomizing core 4 and bottom cap 32 together with the cup body 31. The bottom cap 32 covers the cup body 31, and the atomizing core 4 is inserted into the oil storage component.

[0103] See Figure 9 Step S223, top cover 33 closes the cup body 31.

[0104] In some embodiments, the present application provides an atomizing device including an oil storage component prepared using the oil storage component preparation method of any of the above embodiments.

[0105] The atomizing device in the above embodiments improves the uniformity of e-liquid distribution within the oil storage medium, reduces the risk of oil leakage, and enhances the atomization effect.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
