Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generators, in particular to a pre-oil-filled oil core separation atomization structure and an aerosol generator. Background Art

[0002] The atomizer is the core of the aerosol generator, but the oil leakage problem is a major problem that plagues this field. In order to solve the oil leakage problem, there are many oil core separation atomizers on the market. Before use, the smoke oil is sealed separately and separated from the atomizer core. When in use, the sealed space of the smoke oil is opened through manual operation, so that the smoke oil penetrates into the heating wire through the oil guide cotton, and then the heating wire heats the smoke oil to evaporate, allowing the user to inhale. However, it takes time for the smoke oil to completely penetrate the heating wire. This time is affected by many factors such as the material and volume of the oil guide cotton, and the viscosity of the smoke oil, resulting in an uncertain time. Users often use it before the smoke oil completely penetrates the heating wire, which can easily cause dry burning and burn the core. Utility Model Content

In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0034] See Figures 1 to 7 In the specific embodiment shown, the present utility model discloses a pre-filled oil core separation atomization structure, including: an oil storage body 10, a sealing body 20, an atomization assembly 30, an atomization seat 40, and a base 50. The oil storage body 10, the sealing body 20, and the atomization assembly 30 form an oil storage cavity 60. The atomization seat 40 is connected to the lower end of the atomization assembly 30. The atomization seat 40 is provided with a pre-filled oil port 41. The base 50 is located at the lower end of the atomization seat 40 and is movably connected to the oil storage body 10. After the oil storage cavity 60 is filled with e-liquid, pre-fill the atomization assembly 30 with e-liquid and seal the glue along the pre-filled oil port 41, and install the base 50 to block the oil storage cavity 60 to complete the assembly.

[0035] Specifically, see Figure 2 As shown, after the oil storage body 10, the sealing body 20, the atomization assembly 30, and the atomization seat 40 are assembled, the end of the oil storage body 10 with the mouthpiece end is placed downward (i.e., inverted), and then e-liquid is injected into the oil storage cavity 60 until it is full. Then, pre-fill the atomization assembly 30 with e-liquid (a small amount of e-liquid) along the pre-filled oil port 41, seal the pre-filled oil port 41 with glue, and finally install the base 50 to block the oil storage cavity 60 to complete the assembly. It is also possible to first pre-fill the atomization assembly 30 with e-liquid and seal the glue through the pre-filled oil port 41, and then inject e-liquid into the oil storage cavity 60 until it is full. Thus, it can be seen that by pre-soaking the wicking cotton and heating wire with a small amount of e-liquid in advance, it is possible to avoid the situation where the e-liquid in the oil storage body 10 has not fully soaked into the heating wire when the user uses it, resulting in dry burning and wick burning. In addition, the pre-filled oil method enables the aerosol generator to provide a stable and uniform smoke effect when it is used for the first time, avoiding the problem of unstable smoke quality caused by uneven e-liquid supply or dry burning, thereby improving the user experience.

[0036] In one embodiment, a glue dispensing groove 42 is further provided at the position of the pre-filled oil port 41 on the atomization seat 40.

[0037] Specifically, see Figure 2 , Figure 3 ,Figure 4 and Figure 6 As shown, the pre-oil filling port 41 is located in the area of ​​the glue dispensing groove 42. After the atomizer assembly 30 is pre-filled with oil, glue is filled into the glue dispensing groove 42 to play a sealing role to prevent the smoke oil from leaking from the atomizer assembly 30, thereby ensuring the stability and safety of the device during use.

[0038] Preferably, the atomizer seat 40 is provided with multiple channels on the outside of the dispensing groove 42, so that the jig (i.e., the base 50 may be provided with support blocks corresponding to the channels, and the support blocks pass through the channels and abut against the bottom of the sealing body 20) is supported on the sealing body 20 through the channels. The sealing body 20 is made of silicone material and has the characteristics of high temperature resistance and corrosion resistance.

[0039] In one embodiment, oil filling holes 21 are provided on both sides of the sealing body 20 , and the base 50 is provided with oil sealing columns 51 corresponding to the oil filling holes 21 .

[0040] Specifically, see Figures 3 to 7 As shown, after the oil storage chamber 60 is filled with tobacco oil along the oil filling hole 21, the oil sealing column 51 is inserted into the oil filling hole 21 to form an interference fit to play a sealing role, thereby effectively preventing tobacco oil from leaking from the oil filling hole 21, which is crucial to ensure that the tobacco oil is safely and stably stored in the oil storage chamber 60.

[0041] In one embodiment, the atomizer seat 40 is provided with a needle hole 43 corresponding to the oil filling hole 21 , and the oil sealing column 51 passes through the needle hole 43 and is inserted into the oil filling hole 21 .

[0042] Specifically, see Figures 3 to 7 As shown, the needle hole 43 and the oil filling hole 21 are coaxial, which means that the oil sealing column 51 can accurately and smoothly pass through the needle hole 43 and be inserted into the oil filling hole 21, thereby achieving a tight sealing effect. Through this design, the smoke oil is effectively sealed in the oil storage chamber 60, preventing the smoke oil from leaking from the oil filling hole 21. In addition, since the needle hole 43 and the oil filling hole 21 are coaxial, the oil sealing column 51 can be easily inserted and passed through the needle hole 43 and the oil filling hole 21, without the need for complicated alignment or adjustment operations, which greatly simplifies the sealing process. In addition, after the oil sealing column 51 is fully inserted and passed through the needle hole 43 and the oil filling hole 21, it can be firmly fixed in place, enhancing the stability of the entire structure.

[0043] In one embodiment, the atomizer seat 40 is further provided with a positioning post 44 at a position offset from the needle hole 43 , and the sealing body 20 is provided with a positioning hole 22 corresponding to the positioning post 44 .

[0044] Specifically, see Figures 5 to 7As shown, the number of positioning posts 44 and needle passing holes 43 is both two, and they are staggered and evenly distributed on the atomizing base 40. By providing the positioning posts 44, it is convenient to position the sealing body 20 during assembly and make the needle passing hole 43 and the oil injection hole 21 coaxial. This enables the oil sealing post 51 to smoothly pass through the needle passing hole 43 and accurately insert into the oil injection hole 21, thereby ensuring the reliability and tightness of the seal. In addition, by providing the positioning posts 44 and the positioning holes 22, the assembly process between the atomizing base 40 and the sealing body 20 is greatly simplified, and rapid and accurate assembly between the two can be achieved without complex alignment or adjustment operations.

[0045] In one embodiment, the atomizing base 40 is provided with a mounting post 45, the lower end of the atomizing assembly 30 is connected to the mounting post 45, and the upper end of the atomizing assembly 30 passes through the sealing body 20 and is slidably connected to the oil storage body 10.

[0046] Specifically, referring to Figures 2 to 7 As shown, the mounting post 45 is located at the central position of the atomizing base 40, and the lower end of the atomizing assembly 30 is sleeved on the mounting post 45. The mounting post 45 is provided with an air inlet hole, which communicates with the atomizing assembly 30. The atomizing assembly 30 communicates with the mouthpiece end. The atomizing assembly 30 is used to heat and atomize the e-liquid to generate smoke, and then the smoke flows out along the mouthpiece end for the user to inhale. In addition, the atomizing base 40 is slidably connected to the inner wall of the oil storage body 10, and the oil storage body 10 is provided with a receiving cavity at the position corresponding to the upper end of the atomizing assembly 30; when in the pre-oiling state, the upper end of the atomizing assembly 30 is located in the receiving cavity but does not contact the top of the receiving cavity; when in the use state, the upper end of the atomizing assembly 30 abuts against the top of the receiving cavity.

[0047] In one embodiment, the atomizing assembly 30 is provided with an oil inlet hole 311; when the base 50 and the oil storage body 10 are in the first connection state (i.e., the pre-oiling state), the oil inlet hole 311 is located in the side wall of the sealing body 20 or below the sealing body 20, and the e-liquid cannot enter the atomizing assembly 30. When the base 50 and the oil storage body 10 are in the second connection state (i.e., the use state), the oil inlet hole 311 communicates with the oil storage cavity 60, and the e-liquid can enter the atomizing assembly 30.

[0048] Specifically, referring to Figures 2 to 7As shown, after the pre-injection of oil is completed, the base 50 is assembled with the oil storage body 10. At this time, the base 50 is not fully inserted into the oil storage body 10 (i.e., the first connection state), and the oil inlet hole 311 is located in the side wall of the sealing body 20 or below the sealing body 20 (preferably, the oil inlet hole 311 is located in the side wall of the sealing body 20), which plays a sealing role, so that the e-liquid cannot enter the atomization assembly 30 along the oil inlet hole 311; when in the use state, that is, the base 50 is fully inserted into the oil storage body 10 (i.e., the second connection state), during this process, the base 50 drives the atomization seat 40 to move along the inner wall of the oil storage body 10 towards the mouthpiece end direction, so that the oil inlet hole 311 is separated from the side wall of the sealing body 20 until it is above the sealing body 20, so that the oil inlet hole 311 communicates with the oil storage cavity 60, and the e-liquid can enter the atomization assembly 30 along the oil inlet hole 311.

[0049] In one embodiment, the base 50 is provided with an installation buckle 52, and the oil storage body 10 is provided with a lower buckle position hole 11 and an upper buckle position hole 12; when the installation buckle 52 is connected to the lower buckle position hole 11, the base 50 and the oil storage body 10 are in the first connection state, and when the installation buckle 52 is connected to the upper buckle position hole 12, the base 50 and the oil storage body 10 are in the second connection state.

[0050] Specifically, referring to Figures 2 to 7 As shown, installation buckles 52 are provided on both sides of the base 50. When the base 50 is pushed into the oil storage body 10, the installation buckle 52 is fastened at the lower buckle position hole 11, and the sealing oil column 51 passes through the needle hole 43 and has an interference fit with the oil injection hole 21 to achieve a sealing effect. At this time, the oil inlet hole 311 abuts against the side wall of the sealing body 20, and the e-liquid in the oil storage body 10 is completely sealed, reaching the state of oil-core separation; when the base 50 is further pushed in, the installation buckle 52 is fastened at the upper buckle position hole 12. At this time, the oil inlet hole 311 is above the sealing body 20, and the e-liquid in the oil storage body 10 can enter the atomization assembly 30 through the oil inlet hole 311, reaching the use state.

[0051] In one embodiment, a step position is further provided on the inner wall of the oil storage body 10, and the upper surface of the sealing body 20 abuts against the step position.

[0052] Specifically, referring to Figures 2 to 4 As shown, the step position provides a clear positioning point for the sealing body 20, ensuring that the sealing body 20 can be accurately placed inside the oil storage body 10 during the assembly process, avoiding misalignment or inclination. Once the upper surface of the sealing body 20 abuts against the step position, a stable connection is formed, which helps to fix the sealing body 20 and prevent it from moving or falling off during the use of the electronic cigarette (i.e., the aerosol generator). In addition, the abutting relationship between the step position and the upper surface of the sealing body 20 can further improve the sealing performance of the internal structure of the electronic cigarette, which helps to prevent e-liquid leakage, reduce the entry of external impurities into the electronic cigarette, and maintain the stable performance of the electronic cigarette.

[0053] Preferably, a limiting steel sheet 70 is further provided between the sealing body 20 and the step position. The limiting steel sheet 70 is provided with openings corresponding to the oil injection hole 21 and the positioning hole. The limiting steel sheet 70 plays a role in limiting the sealing body 20 to prevent the sealing body 20 from disengaging from the step position upward; in addition, the limiting steel sheet 70, as an additional support structure, can enhance the stability of the sealing body 20 at the step position, which helps to prevent the sealing body 20 from being displaced or deformed when subjected to external pressure or vibration, and ensures the normal operation of the electronic cigarette.

[0054] Specifically, referring to Figures 2 to 7 As shown, the atomization assembly 30 includes an atomization outer tube 31, an outer oil guiding cotton 32, an atomization inner tube 33, an inner oil guiding cotton 34, a heating wire 35 and a glass fiber tube 36; the atomization outer tube 31 is provided with the oil inlet hole 311, and the outer oil guiding cotton 32, the atomization inner tube 33, the inner oil guiding cotton 34, the heating wire 35 and the glass fiber tube 36 are all arranged inside the atomization outer tube 31; wherein, the heating wire 35 is located at the center, the inner oil guiding cotton 34 is located on the outer periphery of the heating wire 35, the atomization inner tube 33 is located on the outer periphery of the inner oil guiding cotton 34, the outer oil guiding cotton 32 is located on the outer periphery of the atomization inner tube 33, the glass fiber tube 36 is located above the inner oil guiding cotton 34 and inside the atomization inner tube 33; in addition, the atomization inner tube 33 is provided with an opening corresponding to the position of the inner oil guiding cotton 34, and the pins of the heating wire 35 pass downward through the atomization base 40 and are electrically connected to the electrode 80 inserted along the base 50 to form an electrical connection to realize power supply.

[0055] Among them, when performing pre-injection of oil, pre-injection of oil is carried out on the outer oil guiding cotton 32 through the pre-injection oil port 41 to achieve the effect of soaking the heating wire 35 with e-liquid in advance. In addition, the e-liquid in the oil storage cavity 60 soaks along the path of the oil inlet hole 311, the outer oil guiding cotton 32, the opening, and the inner oil guiding cotton 34 in sequence, and finally soaks onto the heating wire 35 to reach the use state.

[0056] Among them, silica gel is provided at the top of the atomization outer tube 31, and the silica gel forms an interference fit with the oil storage body 10 and the atomization outer tube 31 to achieve a sealing effect.

[0057] Referring to Figure 8 In the specific embodiment shown, the present invention also discloses an aerosol generator, including the pre-injection type oil core separation atomization structure as described above and a sleeve 90, and the sleeve 90 is connected to the base 50.

[0058] Specifically, the sleeve 90 is a jig. During assembly, the jig passes through multiple channels provided in the atomization base 40, pushes the base 50 and the atomization base 40 to move upward, and is fastened at the lower buckling position hole 11 to position the sealing body 20 in height. After assembly (that is, when the base 50 and the oil storage body 10 are in the second connection state), the jig is taken out.

[0059] Specifically, the aerosol generator is provided with a pre-injection oil port on the atomization base. After the oil storage cavity is filled with e-liquid, pre-injection of e-liquid and sealing glue are performed along the pre-injection oil port towards the atomization component, and then the base is installed to block the oil storage cavity to complete the assembly. That is, by using a small amount of e-liquid to soak the wicking cotton and heating wire in advance, it is avoided that when the user uses it, the e-liquid in the oil tank body has not completely soaked into the heating wire and is used, resulting in dry burning and wick clogging, effectively improving the service life of the aerosol generator.

[0060] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
