[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] This utility model discloses a large-capacity, leak-proof oil structure, comprising an oil cup 1, an oil cup support 2, a heating element 3, a suction nozzle 4, a core outer tube 5, and an air passage tube 6. The oil cup support 2 is connected to the bottom of the oil cup 1, and the suction nozzle 4 is movably connected to the top of the oil cup 1. The core outer tube 5 and the air passage tube 6 are respectively fixed to the bottom of the suction nozzle 4, with the air passage tube 6 located inside the core outer tube 5. The heating element 3 is connected to the oil cup support 2, and the core outer tube 5 is sleeved on the outside of the heating element 3. The heating element 3 has a first oil inlet 31 and a first air inlet structure. The core outer tube 5 has a second oil inlet 51, and the air passage tube 6 has a second air inlet structure. When the suction nozzle 4 is adjusted to the working position, the first oil inlet 31 is aligned with the second oil inlet 51, and the first air inlet structure and the second air inlet structure are connected. When the suction nozzle 4 is adjusted to the non-working position, the first oil inlet 31 is offset from the second oil inlet 51, and the first air inlet structure and the second air inlet structure are misaligned and not connected.
[0031] The oil cup 1 stores e-liquid. The first oil inlet 31 of the heating element 3 allows e-liquid to enter the oil storage cotton inside the heating element 3, where it is atomized by the heating core. The bottom of the oil cup support 2 has a support through hole 21, which connects to the internal air passage of the heating element 3. Combined with the structure of the mouthpiece 4, air flows into the heating element 3 when the user inhales, providing airflow for the heating core. Therefore, for the heating element 3 to function normally, both the oil passage and the air passage must be open simultaneously for heating and atomization to be achieved. The outer tube 5 of the coil is positioned between the oil cup 1 and the heating element 3. The opening and closing of the oil passage between the heating element 3 and the oil cup 1 is controlled by adjusting the position of the second oil inlet 51 on the outer tube 5 relative to the first oil inlet 31 of the heating element 3. The air passage 6 is positioned between the mouthpiece 4 and the heating element 3. The opening and closing of the air passage inside the heating element 3 is controlled by adjusting the position of the second air intake structure on the air passage 6 relative to the first air intake structure of the heating element 3. Moreover, the position changes of the outer tube 5 and the air passage tube 6 can be achieved simultaneously by adjusting the position of the nozzle 4, which is convenient to operate. During transportation and storage, the nozzle 4 can be moved to a non-working position to disconnect the oil and air passages, avoiding the risk of oil leakage. Even if you suck in this state, the heating element 3 cannot conduct airflow for heating, avoiding accidental sucking that could burn the heating core.
[0032] The large-capacity, leak-proof e-liquid structure also includes a sealing ring 41, which is fitted onto the mouthpiece 4, sealing the mouthpiece 4 to the e-liquid cup 1. The mouthpiece 4 has at least one sealing groove 42 on its outer side, with a sealing ring 41 connected within each groove. The sealing ring 41 seals the connection between the mouthpiece 4 and the e-liquid cup 1, preventing e-liquid from leaking out of the mouthpiece 4.
[0033] Based on the above-mentioned oil and gas circuit adjustment structure, this utility model provides the following two implementation methods.
[0034] Example 1:
[0035] like Figures 1 to 5 As shown, the large-capacity open-oil leak-proof structure also includes a core lower colloid 7, which is connected inside the oil cup bracket 2. The core lower colloid 7 is provided with a limiting groove 71. The bottom of the core outer tube 5 is inserted into the oil cup bracket 2 and cooperates with the limiting groove 71. The edge of the suction nozzle 4 is provided with a limiting step 43. The top of the oil cup 1 is provided with a suction nozzle sliding wall 11. The suction nozzle 4 is movably connected to the suction nozzle sliding wall 11. When in working condition, the suction nozzle 4 is pressed and moved until the bottom of the core outer tube 5 contacts the bottom of the limiting groove 71. When not in working condition, the suction nozzle 4 is pulled up and moved until the limiting step 43 contacts the bottom of the suction nozzle sliding wall 11.
[0036] The mouthpiece 4 has a sealing groove 42 on its side wall for installing a sealing ring 41. The mouthpiece 4 is in sealed contact with the mouthpiece sliding wall 11 through the sealing ring 41 to prevent e-liquid from leaking out of the mouthpiece 4. When the mouthpiece 4 is pressed or pulled up, the sealing ring 41 will move with the mouthpiece 4 to maintain the seal between the mouthpiece 4 and the mouthpiece sliding wall 11. While sealing the bottom of the heating element 3 with the oil cup 1, the lower core colloid 7 limits the lowest position of the outer core tube 5 by the limiting groove 71 on the lower core colloid 7. The limiting step 43 of the suction nozzle 4 and the bottom of the suction nozzle sliding wall 11 limit the highest position of the suction nozzle 4. When the user operates the oil circuit and the air circuit, he / she only needs to press the suction nozzle 4 until it can no longer be pressed down. At this time, the outer core tube 5 is pushed to the lowest point of the limiting groove 71 of the lower core colloid 7. When the user needs to operate the oil circuit and the air circuit, he / she only needs to pull up the suction nozzle 4 until the limiting step 43 is pushed up. The operation is simple and it is also convenient for the user to judge the insertion and removal position.
[0037] The large-capacity open-oil leak-proof structure also includes a lower colloid 8 for the oil cup. The lower colloid 8 is connected to the top of the oil cup bracket 2. The lower colloid 8 is provided with an oil inlet channel 81, which is connected to the inner cavity of the oil cup 1 and the first oil inlet hole 31 respectively. The outer tube 5 of the core is connected to the lower colloid 8 and is located between the oil inlet channel 81 and the first oil inlet hole 31. In the working state, the second oil inlet hole 51 is aligned with the first oil inlet hole 31. In the non-working state, the second oil inlet hole 51 is aligned with the lower colloid 8.
[0038] The oil inlet channel 81 is opened inside the colloid 8 under the oil cup, forming an oil supply path. The e-liquid in the oil cup 1 flows directly to the position of the first oil inlet hole 31 through the guide of the oil inlet channel 81. When the second oil inlet hole 51 is located at the first oil inlet hole 31, the e-liquid in the oil inlet channel 81 enters the heating element 3 through the second oil inlet hole 51 and the first oil inlet hole 31. When the second oil inlet hole 51 is offset from the first oil inlet hole 31, the oil path of the oil inlet channel 81 will be blocked by the outer wall of the outer tube 5 of the core and cannot flow into the first oil inlet hole 31.
[0039] The second oil inlet 51 on the outer tube 5 of the core can be positioned so that when the outer tube 5 is lowered to its lowest point, the second oil inlet 51 aligns with the first oil inlet 31. This way, when the user presses the nozzle 4, the oil circuit is opened when the pressure is reduced to the lowest point. When the nozzle 4 is pulled up to its highest position, the second oil inlet 51 can be offset from the first oil inlet 31 and enter the lower colloid 8 of the oil cup. The lower colloid 8 of the oil cup seals the second oil inlet 51, isolating the oil inlet channel 81 and the first oil inlet 31 by the outer tube 5, thus preventing oil supply.
[0040] The inner walls of the lower coil colloid 7 and the lower oil cup colloid 8 are equipped with sealing ribs 9, which seal the lower coil colloid 7 and the lower oil cup colloid 8 to the outer coil tube 5. The sealing ribs 9 ensure that the e-liquid flows within the oil inlet channel 81, preventing leakage from the gaps in the lower coil colloid 7 and the lower oil cup colloid 8.
[0041] The second air intake structure includes an airway sealant 61 and a tube inlet 62 disposed on the side wall of the airway tube 6. The top of the airway sealant 61 is connected to the bottom of the airway tube 6, and the bottom of the airway sealant 61 is provided with a sealing rib 9. The first air intake structure includes an airway opening 32 disposed on the top of the heating element 3 and an airway chamber 33 disposed inside the heating element 3. The airway opening 32 communicates with the airway chamber 33. In the working state, the airway tube 6 is inserted into the airway chamber 33 from the airway opening 32, and the tube inlet 62 is located inside the airway chamber 33. In the non-working state, the airway tube 6 is pulled up until the sealing rib 9 at the bottom of the airway sealant 61 blocks the airway opening 32, and the tube inlet 62 is located outside the airway chamber 33.
[0042] The airway opening 32 is a constricted structure relative to the airway chamber 33. The diameter of the airway opening 32 is larger than the diameter of the airway tube 6 and smaller than the diameter of the bottom sealing rib 9 of the airway sealant 61. During operation, the airway tube 6 and the airway sealant 61 are pressed into the airway chamber 33 together. The airway tube 6 can move freely at the airway opening 32. When the nozzle 4 is pressed into the outer tube 5 of the core and reaches the bottom of the limiting groove 71, the air inlet 62 of the airway tube 6 is also located in the airway chamber 33. The airflow can directly enter the air inlet 62 of the tube from the airway chamber 33 and pass to the nozzle 4, realizing the flow of air. When the nozzle 4 is pulled up to the limit step 43 and hits the bottom of the nozzle sliding wall 11, the airway tube 6 is moved out of the airway chamber 33. At this time, the air inlet 62 of the tube body is also located outside the airway chamber 33. At the same time, the sealing rib 9 of the airway sealant 61 contacts the inner wall of the airway opening 32, sealing the airflow in the airway chamber 33. At this time, the airflow cannot flow out from the airway chamber 33 to the air inlet 62 of the tube body, thus disconnecting the airway.
[0043] This embodiment controls whether e-liquid in the tank enters the heating element and simultaneously whether the airflow orifice is blocked by plugging and unplugging the mouthpiece 4. Controlling the e-liquid intake of the heating element: By plugging and unplugging the mouthpiece 4, the e-liquid in the tank is controlled to enter the heating element. Controlling the opening and closing of the mouthpiece 4's airflow orifice: By plugging and unplugging the mouthpiece 4, the e-liquid tank is closed, simultaneously closing the airflow of the electronic atomizer to prevent malfunction.
[0044] The working principle of this embodiment is as follows:
[0045] like Figure 3As shown, when in use, after pressing the mouthpiece 4, the travel of the outer tube 5 of the core is limited by the lower colloid 7. After the mouthpiece 4, the outer tube 5 of the core, the air passage tube 6 and the air passage sealant 61 reach the corresponding positions, the oil inlet channel 81 and the air passage are open. When inhaling, the e-liquid in the oil cup 1 can continuously enter the heating core, and the airflow can reach the mouth of the mouthpiece 4.
[0046] like Figure 4 As shown, when not in use, when the mouthpiece 4 is pulled up, the oil cup 1 limits the stroke of the mouthpiece 4. After the mouthpiece 4, the outer tube 5 of the coil, the air passage tube 6 and the air passage sealant 61 reach the corresponding positions, the oil inlet channel 81 and the air passage are closed. The e-liquid in the oil cup 1 will not enter the heating coil, and the e-liquid will not leak outside the device. In addition, there will be no airflow generated by the mouthpiece 4, so the heating coil will not work and will not become unusable due to dry burning of the heating coil caused by accidental inhalation.
[0047] This embodiment solves the oil leakage problem by allowing the oil inlet channel 81 and air passage to be closed by plugging and unplugging, and also prevents the heating coil from burning due to accidental vaping when no e-liquid enters the coil.
[0048] Example 2:
[0049] like Figures 6 to 14 As shown, the mouthpiece 4 has a rotating latch 44 and a limiting ring 45 on its edge, and a mouthpiece rotating wall 12 on the top of the oil cup 1. The mouthpiece 4 is rotatably connected to the mouthpiece rotating wall 12. The mouthpiece rotating wall 12 has a rotating protrusion 13. A limiting groove 46 is formed between the rotating latch 44 and the limiting ring 45, and the rotating protrusion 13 is locked in the limiting groove 46. The mouthpiece 4 is restricted to the position of the rotating protrusion 13 by the limiting groove 46. In this structure, the mouthpiece 4 cannot move up and down relative to the mouthpiece rotating wall 12. Instead, the mouthpiece 4 can rotate relative to the mouthpiece rotating wall 12. The opening and closing of the oil passage and the air passage are switched by rotating the mouthpiece 4. The rotating latch 44 can restrict the rotation position of the mouthpiece 4, and multiple sealing grooves 42 can be provided on the limiting ring 45 for installing the sealing ring 41, so that the mouthpiece 4 and the mouthpiece rotating wall 12 are sealed together to prevent e-liquid from leaking out of the mouthpiece 4.
[0050] The top of the oil cup 1 is provided with a first limiting rib 14 and a second limiting rib 15. In the working state, the rotating latch 44 rotates to contact the first limiting rib 14, and in the non-working state, the rotating latch 44 rotates to contact the second limiting rib 15. The first limiting rib 14, the second limiting rib 15, and the rotating latch 44 of the nozzle 4 form a rotating limiting structure. The directions of the first limiting rib 14 and the second limiting rib 15 are perpendicular to each other. The nozzle 4 can be configured with two rotating latches 44 distributed at 180° to each other. When the first rotating latch 44 contacts the first limiting rib 14, the oil passage and the air passage are connected. When the second rotating latch 44 contacts the second limiting rib 15, the nozzle 4 rotates exactly 90°, and the oil passage and the air passage switch from the connected state to the closed state.
[0051] The large-capacity open-oil leak-proof structure also includes a lower colloid 8 for the oil cup. The lower colloid 8 is connected to the top of the oil cup support 2. The lower colloid 8 has an oil inlet area 82 and a sealing area 83. The oil inlet area 82 and the sealing area 83 are adjacent to each other. The oil inlet area 82 is respectively connected to the inner cavity of the oil cup 1 and the first oil inlet hole 31. The outer tube 5 of the core is connected to the lower colloid 8 of the oil cup and is located between the lower colloid 8 of the oil cup and the first oil inlet hole 31. In the working state, the outer tube 5 of the core rotates to align the second oil inlet hole 51 with the oil inlet area 82. In the non-working state, the outer tube 5 of the core rotates to align the second oil inlet hole 51 with the sealing area.
[0052] The oil inlet areas 82 and 83 are arranged in a 180° opposing pattern, and the closed areas 83 are also arranged in a 180° opposing pattern. That is, the oil inlet areas 82 and 83 are staggered every 90°. The oil inlet areas 82 connect to the e-liquid in the oil cup 1, allowing the e-liquid to flow towards the heating element 3. The closed areas 83 are blocked by the lower colloid 8 of the oil cup, preventing e-liquid from flowing into them. The first oil inlet hole 31 of the heating element 3 is always aligned with the oil inlet area 82. When the second oil inlet hole 51 of the outer coil tube 5 rotates to align with the first oil inlet hole 31, the oil inlet areas 82 and the heating element 3 are connected, allowing e-liquid to flow into the heating element 3. When the outer coil tube 5 rotates 90° with the mouthpiece 4, the second oil inlet hole 51 is blocked by the lower colloid 8 of the closed area 83, and the connection between the oil inlet areas 82 and the first oil inlet hole 31 is also blocked by the wall of the outer coil tube 5, thus closing the oil path.
[0053] The second air intake structure includes an air passage valve 63, which is connected to the bottom of the air passage tube 6. The first air intake structure includes a core-on-colloid 34, which is connected to the top of the heating element 3. The air passage valve 63 and the core-on-colloid 34 are mated together. The air passage valve 63 is provided with a valve body air inlet 64, and the core-on-colloid 34 is provided with a colloid air inlet 35. In the working state, the air passage tube 6 rotates until the valve body air inlet 64 is aligned with the colloid air inlet 35. In the non-working state, the air passage tube 6 rotates until the valve body air inlet 64 is offset from the colloid air inlet 35.
[0054] When the airway valve 63 and the colloid 34 on the core are aligned at 0° or 180°, the air inlet 64 of the valve body and the air inlet 35 of the colloid are connected. After the airway valve 63 rotates 90° together with the airway tube 6, the air inlet 64 of the valve body and the air inlet 35 of the colloid are misaligned. At this time, the air inlet 64 of the valve body is blocked by the colloid 34 on the core, while the air inlet 35 of the colloid is blocked by the valve body of the airway valve 63. The two sides cannot be connected, thus closing the airway.
[0055] This embodiment controls whether e-liquid in the oil tank enters the heating element by rotation, and simultaneously whether the airflow hole is blocked. The method for controlling whether e-liquid enters the heating element is: by rotating the mouthpiece 4, the e-liquid in the oil tank enters the heating element through the oil inlet hole. The method for controlling whether airflow is generated in the airflow hole of the mouthpiece 4 is: by rotating the mouthpiece 4, the airflow in the airflow hole of the mouthpiece 4 is controlled.
[0056] The working principle of this second embodiment is as follows:
[0057] like Figures 8 to 9 As shown, when in use, the arrow indicates VAPE. After the mouthpiece 4, outer coil tube 5, airway tube 6, and airway valve 63 are in the corresponding positions, the oil inlet channel 81 and the airway are open. When inhaling, the e-liquid in the oil cup 1 can continuously enter the heating element 3, and the airflow can reach the mouth of the mouthpiece 4.
[0058] like Figures 10 to 12 As shown, when not smoking, rotate 90° until the arrow indicates CLOSE. After the mouthpiece 4, outer coil tube 5, airway tube 6, and airway valve 63 reach the designated positions, the oil inlet channel and airway are closed. E-liquid from oil cup 1 will not enter the heating element 3, and the e-liquid will not leak outside the device. Furthermore, no airflow will be generated from the mouthpiece 4, so the heating element will not work and will not become unusable due to accidental inhalation causing the heating element to burn out.
[0059] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
