Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more specifically, to a multi-core electronic atomization device and its control method. Background Technology

Existing electronic atomizing devices generally include a housing, an atomizing coil, a liquid reservoir, a battery, and a controller. A mouthpiece is connected to the housing, and the mouthpiece has a mist outlet. The atomizing coil is installed in the liquid reservoir. The atomizing coil and the mouthpiece are interconnected, and the liquid reservoir stores the atomized liquid. The atomizing coil includes a liquid guide rope, around which a heating wire is wound. The heating wire is electrically connected to the battery and controller. In use, the controller controls the battery to power the heating wire, and the atomized liquid is atomized at the high temperature of the heating wire, producing a certain amount of aerosol, which can then be inhaled.

[0003] To avoid insufficient liquid supply causing the heating wire to burn out, those skilled in the art have added an atomizing core to the existing liquid storage device. The two atomizing cores are arranged side by side with a gap between them, each located in a ventilation channel. During operation, the two atomizing cores work alternately. However, when a user inhales the aerosol atomized by one atomizing core, they also passively inhale air from the air passage of the other atomizing core, resulting in low aerosol concentration and poor taste.

[0011] Preferably, the porous liquid suction element is provided with an exhaust vent, which is located between the first exhaust groove and the atomizing chamber. The exhaust vent extends longitudinally along the porous liquid suction element and extends to the end face of the porous liquid suction element. The first side and the second side of the exhaust vent are positioned opposite each other. The first exhaust groove is located on the first side of the exhaust vent, and the first atomizing chamber is located on the second side of the exhaust vent. The exhaust vent extends to the groove surface of the first exhaust groove and the cavity surface of the first atomizing chamber.

[0012] Preferably, the surface of the second end wall facing the porous liquid suction element is provided with a pressure relief groove, the first end of the first exhaust groove is connected to the pressure relief groove, and the second end of the first exhaust groove is connected to the ventilation gap.

[0013] Preferably, the surface of the liquid storage component facing the nozzle is provided with a first flow-blocking groove, the first flow-blocking groove being arranged around the opening of the first mist discharge hole; the nozzle is provided with a first flow-blocking ring portion, the first flow-blocking ring portion being inserted into the first flow-blocking groove.

Therefore, this not only avoids the problem of insufficient atomizing liquid supply leading to dry burning, but also results in a high aerosol concentration, good taste, and relatively stable aerosol emission, avoiding fluctuations in volume.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Please see Figures 1 to 8 This invention provides a multi-core electronic atomizing device, including a mouthpiece 1, a housing 2, a liquid storage component 3, a fixing bracket 4, a porous liquid suction component 5, a first atomizing core 6, a second atomizing core 7, a third atomizing core 8, a fourth atomizing core 91, and a controller 92. The mouthpiece 1 includes a suction section 11, a first flow-blocking ring section 12, a second flow-blocking ring section 13, and a connecting ring section 14. The suction section 11 has a mist outlet 111 for discharging aerosol. The first flow-blocking ring section 12, the second flow-blocking ring section 13, and the connecting ring section 14 are located on the same side of the suction section 11 and are all connected to the suction section 11. The first flow-blocking ring section 12 is located between the second flow-blocking ring section 13 and the connecting ring section 14. The second flow-blocking ring section 13 communicates with the mist outlet 111, and the connecting ring section 14 is connected to the housing 2.

[0033] The outer casing 2 includes an outer sleeve 21 and a bottom cover 22. The first end of the outer sleeve 21 is fitted onto the connecting ring 14 of the nozzle 1, and the second end of the outer sleeve 21 is fitted onto the bottom cover 22. A snap-fit ​​hole 221 is provided on the side wall of the bottom cover 22. The outer sleeve 21 and the bottom cover 22 form a first storage cavity 23. A battery 93 for power supply is stored in the first storage cavity 23, and the battery 93 is electrically connected to the controller 92.

[0034] The liquid storage component 3 is located within the first receiving cavity 23. A second receiving cavity 301 is provided within the liquid storage component 3. The second receiving cavity 301 includes a first end wall and a second end wall. The first end wall is located between the suction nozzle 1 and the second end wall. A first mist discharge hole 302 and a limiting protrusion 303 are provided on the first end wall. The first mist discharge hole 302 communicates with the suction nozzle 1. A pressure relief groove 304 is provided on the surface of the second end wall facing the porous liquid suction component 5.

[0035] The surface of the liquid storage component 3 facing the nozzle 1 is provided with a first flow-blocking groove 305 and a receiving groove 306. The first flow-blocking groove 305 surrounds the opening of the first mist-expelling hole 302. The first flow-blocking ring 12 is inserted into the first flow-blocking groove 305. Therefore, it not only effectively prevents air from the outer shell 2 from entering the nozzle 1, but also makes the liquid storage component 3 more tightly sealed, preventing the atomized liquid in the liquid storage component 3 from leaking out. The receiving groove 306 communicates with the first mist-expelling hole 302. The receiving groove 306 contains an elastic liquid-absorbing sheet 94 for absorbing condensate. The elastic liquid-absorbing sheet 94 is provided with a second mist-expelling hole 941, which communicates with the first mist-expelling hole 302 and the mist outlet 111. The second flow-blocking ring 13 is inserted into the receiving groove 306 and abuts against the elastic liquid-absorbing sheet 94. The opening of the second mist-expelling hole 941 is located in the space formed by the second flow-blocking ring 13. Therefore, it effectively prevents the aerosol discharged from the second row of mist holes 941 from flowing arbitrarily, reducing the probability of aerosol condensation.

[0036] Specifically, the liquid storage component 3 includes a receiving tube 31, an elastic sealing top cover 32, and an elastic sealing base 33. The receiving tube 31 is located within a first receiving cavity 23. The elastic sealing top cover 32 is inserted into the first end of the receiving tube 31, and the surface of the elastic sealing top cover 32 facing the nozzle 1 is provided with the first flow-blocking groove 305. The elastic sealing base 33 is inserted into the second end of the receiving tube 31, and the second receiving cavity 301 is located within the space formed by the receiving tube 31, the elastic sealing top cover 32, and the elastic sealing base 33. The surface of the elastic sealing base 33 facing the second receiving cavity 301 is provided with the pressure relief groove 304, and the surface of the elastic sealing base 33 facing away from the second receiving cavity 301 is provided with a second flow-blocking groove 331, which is located within the receiving tube 31. The elastic sealing top cover 32 and the elastic sealing base 33 can be made of materials such as silicone or rubber. In one embodiment, the receiving tube 31 and the elastic sealing top cover 32 can be an integrally formed structure.

[0037] The mounting bracket 4 includes a base plate portion 41, a third flow-blocking ring portion 42, and a plug-in ring portion 43. The base plate portion 41 is located on the side of the liquid storage member 3 facing away from the nozzle 1. The base plate portion 41 is provided with a mounting groove 411, in which an airflow sensor 95 is installed. The airflow sensor 95 is electrically connected to the controller 92 and communicates with the nozzle 1 to send a suction signal to the controller 92 when the user inhales. A leakage collection chamber is formed between the base plate portion 41 and the elastic sealing top cover 32. The leakage collection chamber is filled with a leakage absorbent cotton block 96, which is used to absorb leaked atomized liquid.

[0038] The third flow-blocking ring 42 is connected to the base plate 41 and located on the side of the base plate 41 facing the liquid storage component 3. The third flow-blocking ring 42 is inserted into the second flow-blocking groove 331. The third flow-blocking ring 42 and the receiving tube 31 together clamp the groove wall of the second flow-blocking groove 331. Therefore, the outer peripheral surface of the elastic sealing base 33 and the receiving tube 31 can be tightly connected, which effectively prevents the atomized liquid from leaking out of the second receiving cavity 301. The insertion ring 43 is connected to the base plate 41 and located on the side of the base plate 41 facing away from the liquid storage component 3. The outer peripheral surface of the insertion ring 43 is provided with a fastening protrusion 431. The insertion ring 43 is inserted into the bottom cover 22. The fastening protrusion 431 fastens with the fastening hole 221, thereby fastening the fixed bracket 4 to the bottom cover 22. This not only facilitates assembly but also ensures a more reliable connection.

[0039] The porous liquid suction element 5 is located within the second receiving cavity 301, and is spaced apart from the first end wall. A ventilation gap 50, communicating with the first mist outlet 302, is formed between the porous liquid suction element 5 and the first end wall. Therefore, in environments with low external air pressure, such as aircraft, air within the ventilation gap 50 can be discharged from the nozzle 1, thus reducing the probability of leakage of atomized liquid from the porous liquid suction element 5. The limiting protrusion 303 is located within the ventilation gap 50, thus preventing the porous liquid suction element 5 from shifting due to vibration or other reasons during transportation, which could lead to blockage of the ventilation gap 50. Preferably, the limiting protrusion 303 is strip-shaped, and its extending direction is the same as the direction of gas flow to the first mist outlet 302. Therefore, the ventilation gap 50 is more unobstructed, not only preventing deformation of the porous liquid suction element 5 that could compress the space of the ventilation gap 50, but also facilitating gas flow.

[0040] The porous liquid suction component 5 is provided with a first atomizing chamber 51, a second atomizing chamber 52, a first exhaust groove 53, an exhaust slit 54, and a second exhaust groove 55. The first atomizing chamber 51 and the second atomizing chamber 52 are arranged side by side and both penetrate through the end face of the porous liquid suction component 5. Both the first atomizing chamber 51 and the second atomizing chamber 52 are connected to the nozzle 1. The first exhaust groove 53 is located on the outer peripheral surface of the porous liquid suction component 5. The first end of the first exhaust groove 53 is connected to the pressure relief groove 304, and the second end of the first exhaust groove 53 is connected to the ventilation gap 50. Therefore, air on the bottom and sides of the porous liquid suction component 5 can be discharged to the nozzle 1, thereby further reducing the probability of leakage of atomized liquid inside the porous liquid suction component 5.

[0041] The exhaust vent 54 is located between the first exhaust groove 53 and the atomizing chamber. The exhaust vent 54 extends longitudinally along the porous liquid suction member 5 and extends to the end face of the porous liquid suction member 5. The first side and the second side of the exhaust vent 54 are positioned opposite each other. The first exhaust groove 53 is located on the first side of the exhaust vent 54, and the first atomizing chamber 51 is located on the second side of the exhaust vent 54. The exhaust vent 54 extends to the groove surface of the first exhaust groove 53 and the cavity surface of the first atomizing chamber 51. Therefore, it is not only convenient to assemble the first atomizing core 6 and the second atomizing core 7, but also allows the air inside the porous liquid suction member 5 to be discharged to the nozzle 1 when the external air pressure is low, further reducing the probability of leakage of atomized liquid inside the porous liquid suction member 5.

[0042] The second exhaust groove 55 is located on the outer peripheral surface of the porous liquid-absorbing component 5. The first end of the second exhaust groove 55 communicates with the pressure relief groove 304, and the second end communicates with the ventilation gap 50. The first exhaust groove 53 and the second exhaust groove 55 are located on opposite sides of the porous liquid-absorbing component 5. The first atomizing chamber 51 and the second atomizing chamber 52 are located between the first exhaust groove 53 and the second exhaust groove 55. Therefore, the exterior of the porous liquid-absorbing component 5 forms a good exhaust passage, thus greatly reducing the risk of atomized liquid leakage. It is understood that the porous liquid-absorbing component 5 can be made of materials such as cotton, ceramic, or porous rubber foam; the material is not specifically limited here, as long as it can absorb the atomized liquid.

[0043] The first atomizing core 6 and the second atomizing core 7 are located at different positions within the first atomizing chamber 51, so that the area where the first atomizing core 6 atomizes the atomized liquid in the first atomizing chamber 51 and the area where the second atomizing core 7 atomizes the atomized liquid in the first atomizing chamber 51 do not overlap during operation. Therefore, both the first atomizing core 6 and the second atomizing core 7 can obtain sufficient atomized liquid, avoiding the problem of insufficient atomized liquid supply leading to dry burning.

[0044] The third atomizing core 8 and the fourth atomizing core 91 are located at different positions within the second atomizing chamber 52, so that the area where the third atomizing core 8 atomizes the atomized liquid in the second atomizing chamber 52 does not overlap with the area where the fourth atomizing core 91 atomizes the atomized liquid in the second atomizing chamber 52. Therefore, the third atomizing core 8 and the fourth atomizing core 91 can obtain sufficient atomized liquid, avoiding the problem of insufficient atomized liquid supply and thus dry burning. The first atomizing core 6 and the fourth atomizing core 91 form a first working group, and during operation, the first atomizing core 6 and the fourth atomizing core 91 in the first working group work simultaneously. The second atomizing core 7 and the third atomizing core 8 form a second working group, and during operation, the second atomizing core 7 and the third atomizing core 8 in the second working group work simultaneously. Under the control of the controller 92, the first and second working groups work alternately, resulting in a higher aerosol concentration and a longer overall service life.

[0045] To ensure timely replenishment of the atomizing fluid, the first atomizing core 6 and the second atomizing core 7 are located at different axial positions in the first atomizing chamber 51, with the distance between the first atomizing core 6 and the mouthpiece 1 being less than that of the second atomizing core 7. Similarly, the third atomizing core 8 and the fourth atomizing core 91 are located at different axial positions in the second atomizing chamber 52, with the distance between the third atomizing core 8 and the mouthpiece 1 being less than that of the fourth atomizing core 91. In other words, when the invention is placed vertically, the height of the first atomizing core 6 is higher than the height of the second atomizing core 7, and the height of the third atomizing core 8 is higher than the height of the fourth atomizing core 91. This means that the first and second working groups are arranged in a staggered configuration, thus better preventing the problem of insufficient atomizing fluid supply.

[0046] In one embodiment, the resistance values ​​of the first atomizing core 6 and the second atomizing core 7 are both greater than the resistance values ​​of the third atomizing core 8 and the fourth atomizing core 91. The distance from the geometric center of the first atomizing core 6 to the geometric center of the porous liquid-absorbing element 5 is less than the distance from the geometric center of the third atomizing core 8 to the geometric center of the porous liquid-absorbing element 5, and the distance from the geometric center of the second atomizing core 7 to the geometric center of the porous liquid-absorbing element 5 is less than the distance from the geometric center of the fourth atomizing core 91 to the geometric center of the porous liquid-absorbing element 5. This arrangement not only generates a larger aerosol during operation but also avoids the problem of insufficient atomized liquid supply. Preferably, the first atomizing core 6, the second atomizing core 7, the third atomizing core 8, and the fourth atomizing core 91 are located at different longitudinal positions of the porous liquid-absorbing element 5. That is, when the present invention is placed vertically, the heights of the positions of the first atomizing core 6, the second atomizing core 7, the third atomizing core 8, and the fourth atomizing core 91 are all different, thus allowing the atomized liquid to be replenished in a timely manner.

[0047] In another embodiment, the distance between the first atomizing core 6 and the nozzle 1 is equal to the distance between the third atomizing core 8 and the nozzle 1, and the distance between the second atomizing core 7 and the nozzle 1 is equal to the distance between the fourth atomizing core 91 and the nozzle 1. The porosity of the porous liquid suction element 5 in the region between the first atomizing core 6 and the third atomizing core 8 is greater than the porosity in the region between the second atomizing core 7 and the fourth atomizing core 91. Therefore, excessive flow of atomized liquid into the pressure relief groove 304 during vibration is avoided, which could affect the exhaust. Furthermore, it ensures a good supply of liquid to the atomizing cores, avoiding interference issues.

[0048] In this embodiment, specifically, the first atomizing core 6 includes a first fixing tube 61, a first porous liquid guiding column 62, and a first heating element 63. The first fixing tube 61 is located within the first atomizing chamber 51. The first porous liquid guiding column 62 is located within the first fixing tube 61 and contacts the porous liquid suction element 5. The first heating element 63 is located within the first porous liquid guiding column 62 and is electrically connected to the controller 92. The second atomizing core 7 includes a second fixing tube 71, a second porous liquid guiding column 72, and a second heating element 73. The second fixing tube 71 is located within the first atomizing chamber 51. The second porous liquid guiding column 72 is located within the second fixing tube 71 and contacts the porous liquid suction element 5. The second heating element 73 is located within the second porous liquid guiding column and is electrically connected to the controller 92.

[0049] The first fixing tube 61 and the second fixing tube 71 are integrally formed, as are the first porous liquid guiding column 62 and the second porous liquid guiding column 72. This facilitates assembly. The first fixing tube 61 and the second fixing tube 71 can be made of fiberglass tubes, metal tubes, etc., for better high-temperature resistance. The first porous liquid guiding column 62 and the second porous liquid guiding column 72 can be made of porous materials such as cotton or ceramics. The first heating element 63 and the second heating element 73 can be heating wires or heating meshes, etc. It is understood that as long as the atomizing liquid can be atomized, the structure of the first atomizing core 6 and the second atomizing core 7 is not specifically limited here.

[0050] The third atomizing core 8 includes a third fixing tube 81, a third porous liquid guiding column 82, and a third heating element 83. The third fixing tube 81 is located inside the second atomizing chamber 52. The third porous liquid guiding column 82 is located inside the third fixing tube 81 and is in contact with the porous liquid suction element 5. The third heating element 83 is located inside the third porous liquid guiding column and is electrically connected to the controller 92. The fourth atomizing core 91 includes a fourth fixing tube 911, a fourth porous liquid guiding column 912, and a fourth heating element 913. The fourth fixing tube 911 is located inside the second atomizing chamber 52. The fourth porous liquid guiding column 912 is located inside the fourth fixing tube 911 and is in contact with the porous liquid suction element 5. The fourth heating element 913 is located inside the fourth porous liquid guiding column and is electrically connected to the controller 92.

[0051] The third fixing tube 81 and the fourth fixing tube 911 are integrally molded structures, as are the third porous liquid guiding column 82 and the fourth porous liquid guiding column 912. This facilitates assembly. The third fixing tube 81 and the fourth fixing tube 911 can be made of fiberglass tubes, metal tubes, etc., for better high-temperature resistance. The third porous liquid guiding column 82 and the fourth porous liquid guiding column 912 can be made of porous materials such as cotton or ceramics. The third heating element 83 and the fourth heating element 913 can be heating wires or heating meshes, etc. It is understood that as long as the atomizing liquid can be atomized, the structure of the third atomizing core 8 and the fourth atomizing core 91 is not specifically limited here. For example, the first fixing tube 61, the second fixing tube 71, the third fixing tube 81, and the fourth fixing tube 911 may not be necessary.

[0052] The multi-core electronic atomizing device of the present invention also includes a display screen 97, which is located in the first storage cavity 23 and electrically connected to the controller 92. The display screen 97 is used to display information such as battery level and remaining atomizing liquid. Therefore, users can understand the information of the multi-core electronic atomizing device during use, which makes it convenient for users to use.

[0053] Please see Figure 9 The present invention also discloses a control method for a multi-core electronic atomizing device applicable to the above embodiments, comprising the following steps:

[0054] S1. Obtain the first inhalation signal;

[0055] When a user inhales, the airflow sensor 95 is triggered, and the airflow sensor 95 sends an inhalation signal to the controller 92. When the number of inhalation signals generated is odd, the inhalation signal is defined as the first inhalation signal.

[0056] S2. Control the first working group to operate based on the first inhalation signal;

[0057] After receiving the first inhalation signal, the controller 92 controls the first atomizing core 6 and the fourth atomizing core 91 in the first working group to work, so that the first heating element 63 and the fourth heating element 913 heat up, thereby atomizing the atomized liquid.

[0058] S3, Obtain the second inhalation signal;

[0059] When the user inhales again, the airflow sensor 95 is triggered, and the airflow sensor 95 sends an inhalation signal to the controller 92. When the number of inhalation signals generated is even, the inhalation signal is defined as the second inhalation signal.

[0060] S4. Based on the second inhalation signal, control the second working group to work so that the first working group and the second working group take turns working.

[0061] After receiving the second inhalation signal, the controller 92 controls the second atomizing core 7 and the third atomizing core 8 in the second working group to operate, so that the second heating element 73 and the third heating element 83 heat up, thereby atomizing the atomized liquid. In other words, when the user inhales, the controller 92 controls one working group to operate at a time, with the first working group and the second working group working alternately, thus avoiding insufficient supply of atomized liquid and achieving a high aerosol concentration.

[0062] In summary, by placing the first atomizing core 6 and the second atomizing core 7 at different positions within the first atomizing chamber 51, and the third atomizing core 8 and the fourth atomizing core 91 at different positions within the second atomizing chamber 52, this invention forms a first working group with the first atomizing core 6 and the fourth atomizing core 91, and a second working group with the second atomizing core 7 and the third atomizing core 8. During operation, the controller 92 controls the first and second working groups to work alternately. Each time, an atomizing core is active in each atomizing chamber, and the atomization area differs between adjacent atomization cycles within the same atomizing chamber. Therefore, this not only avoids the problem of dry burning due to insufficient atomizing liquid supply, but also results in a high aerosol concentration, good taste, and relatively stable aerosol output, avoiding fluctuations in volume.
