Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic atomizer technology, and in particular to a leak-proof sealing structure for atomizing liquid. Background Technology
[0002] Existing electronic atomization devices generally include a battery pack and an atomizer. The battery pack contains a battery that supplies power to the atomizer. The atomizer includes an atomizing coil mounted on an atomizing base. The atomizing coil includes a liquid conductor and a heating element. When powered on, the heating element heats and atomizes the solution to be atomized, i.e., the atomizing liquid, into an aerosol or mist. The atomizing liquid is the e-liquid stored in the atomizer's reservoir. Electronic atomization devices can be used as electronic cigarettes, herbal atomizing devices, and medicinal atomizing devices, etc.
[0003] Currently, the principle of electronic atomized cigarettes is that the vaporizing agent is heated and vaporized into high-temperature vapor on the electric heating element of the atomization system and sprayed out through the opening. The sprayed vapor expands and condenses into tiny, smoke-like droplets in the atmosphere, thus forming smoke similar to that of traditional cigarettes. However, this approach presents the following problems in actual operation:
[0004] 1. Because existing electronic cigarette products generally adopt an open design, that is, the heating chamber and the airflow channel are connected, leakage is a common problem.
[0005] 2. Traditional electronic cigarette products are usually sealed with rubber and cotton thread. Since the electronic cigarette heater is close to the rubber ring, the rubber ring will be affected by high temperature, making it prone to thermal expansion and contraction when the temperature changes, resulting in seal failure. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide a leak-proof sealing structure for atomizing liquid, in order to address the current open design of electronic cigarettes, which is prone to leakage, and the fact that the liquid storage chamber and heating chamber are generally sealed with rubber sealing rings, which are easily deformed by temperature, thus affecting the sealing effect. In addition, some existing electronic atomizing devices have potential safety issues for children, as children's curiosity and immature judgment may lead them to misoperate or misuse electronic cigarettes, endangering their safety.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] A leak-proof sealing structure for atomizing liquid includes a storage tank, a heated atomizing box fixedly installed on the top of the storage tank, a sealed heating mechanism fixedly installed in the inner cavity of the heated atomizing box, and a sealed nozzle connected to the top of the heated atomizing box.
[0010] The sealed heating mechanism includes a heater, the outer surface of which is fixedly connected to the inner surface of the heating atomizing box, a heating wire is fixedly installed on the top of the heater, and a cotton core is fixedly installed on the inner surface of the heating wire.
[0011] As an improved technical solution, the sealed heating mechanism further includes a sealing rubber ring, on the inner surface of which a memory metal ring is fixedly installed.
[0012] As an improved technical solution, the outer surface of the sealing rubber ring is fixedly connected to the inner surface of the heating atomizing box, and the inner surface of the sealing rubber ring is fixedly connected to the outer surface of the cotton core.
[0013] As an improved technical solution, the sealed nozzle includes an atomizing nozzle, a rotating rod is rotatably mounted on the inner surface of the atomizing nozzle, both ends of the rotating rod penetrate the atomizing nozzle and extend to the outside of the atomizing nozzle, a connecting block is fixedly mounted on the outer surface of the rotating rod, and a sealing plate is provided on the outer surface of the rotating rod away from the connecting block.
[0014] As an improved technical solution, the sealed nozzle also includes a torsion spring, the inner surface of which is fitted onto the outer surface of the rotating rod, one end of which is fixedly connected to the inner wall of the atomizing nozzle, and the other end of which is fixedly connected to the top of the connecting block.
[0015] As an improved technical solution, the sealed nozzle also includes a limiting block, the outer surface of which is fixedly connected to the inner surface of the atomizing nozzle.
[0016] As an improved technical solution, the sealed nozzle further includes a locking assembly, which includes a locking frame. The outer surface of the locking frame is slidably connected to the inner surface of the atomizing nozzle. The front and back of the locking frame penetrate the atomizing nozzle and extend to the outside of the atomizing nozzle. An isolation plate is fixedly installed on the outer surface of the locking frame. A sliding groove is provided at the bottom of the locking frame. A slider is slidably installed on the inner surface of the sliding groove. A pressure spring is fixedly installed at the bottom of the slider. The bottom end of the pressure spring is fixedly connected to the inner surface of the atomizing nozzle.
[0017] As an improved technical solution, the locking component further includes a slot, which is formed on the inner surface of the atomizing nozzle. A locking block is installed on the inner surface of the slot, and the left side of the locking block is fixedly connected to the right side of the locking frame.
[0018] After adopting the above technical solution, the beneficial effects of this utility model are:
[0019] 1. This utility model improves the sealing effect of electronic cigarettes by increasing the sealing effect during heating and atomization. By using the cotton wick and sealing rubber ring in conjunction with the memory metal ring and heating atomization box, the deformation of the memory metal ring compensates for the deformation of the rubber sealing ring when the heater inside the electronic cigarette is heated, thus preventing the atomized liquid from overflowing from the cotton wick.
[0020] 2. This utility model incorporates a child-locking function for electronic cigarettes. This is achieved through the combined use of a torsion spring and sealing plate with a rotating rod and atomizing nozzle; a locking frame and insulating plate with a sealing plate and limiting block; a locking frame, sliding groove, and slider with a pressure spring and locking slot; and a locking slot and locking block. This seals the atomizing nozzle when the electronic cigarette is not in use, preventing the cigarette from being activated by suction if a child accidentally inhales it, thus avoiding harm to the child.

[0033] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a leak-proof sealing structure for atomizing liquid. This leak-proof sealing structure for atomizing liquid includes a storage tank 1, a heating atomizing box 2 fixedly installed on the top of the storage tank 1, a sealed heating mechanism 3 fixedly installed in the inner cavity of the heating atomizing box 2, and a sealed nozzle 4 connected to the top of the heating atomizing box 2.
[0034] The sealed heating mechanism 3 includes a heater 31, the outer surface of which is fixedly connected to the inner surface of the heating atomizing box 2, a heating wire 32 is fixedly installed on the top of the heater 31, and a cotton core 33 is fixedly installed on the inner surface of the heating wire 32.
[0035] Heater 31 is electrically connected to an external power source and is controlled by an external PLC programming program.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the sealed heating mechanism 3 also includes a sealing rubber ring 34, and a memory metal ring 35 is fixedly installed on the inner surface of the sealing rubber ring 34.
[0037] The memory metal ring 35 (nickel-titanium alloy) has a preset deformation temperature of 50-80℃. At low temperatures, the memory metal ring 35 shrinks to provide pre-tightening force, and at high temperatures, the memory metal ring 35 expands to compensate for the thermal deformation of the sealing rubber ring 34.
[0038] like Figure 1 and Figure 4 As shown, the outer surface of the sealing rubber ring 34 is fixedly connected to the inner surface of the heating atomizing box 2, and the inner surface of the sealing rubber ring 34 is fixedly connected to the outer surface of the cotton core 33.
[0039] like Figure 1 and Figure 4 As shown, the sealed nozzle 4 includes an atomizing nozzle 41. A rotating rod 42 is rotatably mounted on the inner surface of the atomizing nozzle 41. Both ends of the rotating rod 42 pass through the atomizing nozzle 41 and extend to the outside of the atomizing nozzle 41. A connecting block 43 is fixedly mounted on the outer surface of the rotating rod 42. A sealing plate 44 is provided on the outer surface of the rotating rod 42 away from the connecting block 43.
[0040] like Figure 1 and Figure 4 As shown, the sealed nozzle 4 also includes a torsion spring 45. The inner surface of the torsion spring 45 is fitted onto the outer surface of the rotating rod 42. One end of the torsion spring 45 is fixedly connected to the inner wall of the atomizing nozzle 41, and the other end of the torsion spring 45 is fixedly connected to the top of the connecting block 43.
[0041] like Figure 1 and Figure 4 As shown, the sealed nozzle 4 also includes a limiting block 46, the outer surface of which is fixedly connected to the inner surface of the atomizing nozzle 41.
[0042] like Figure 1 and Figure 5As shown, the sealed nozzle 4 also includes a locking assembly 47, which includes a locking frame 471. The outer surface of the locking frame 471 is slidably connected to the inner surface of the atomizing nozzle 41. The front and back of the locking frame 471 penetrate the atomizing nozzle 41 and extend to the outside of the atomizing nozzle 41. An isolation plate 472 is fixedly installed on the outer surface of the locking frame 471. A sliding groove 473 is provided at the bottom of the locking frame 471. A slider 474 is slidably installed on the inner surface of the sliding groove 473. A pressure spring 475 is fixedly installed at the bottom of the slider 474. The bottom end of the pressure spring 475 is fixedly connected to the inner surface of the atomizing nozzle 41.
[0043] There are two partition plates 472.
[0044] like Figure 1 and Figure 5 As shown, the locking assembly 47 also includes a slot 476, which is formed on the inner surface of the atomizing nozzle 41. A block 477 is snapped onto the inner surface of the slot 476, and the left side of the block 477 is fixedly connected to the right side of the locking frame 471.
[0045] When using the electronic cigarette, the user first presses the locking frame 471, causing it to move to the left. This disengages the locking block 477 from the slot 476. Then, the pressure spring 475, via the slider 474, moves the locking frame 471 upwards, disengaging it from the sealing plate 44. Next, the user presses the locking frame 471 to the right, re-engaging the locking block 477 with the slot 476. Then, the user can use the electronic cigarette. When a user holds the atomizing nozzle 41 in their mouth and inhales outwards, the airflow causes the sealing plate 44 to rotate, opening the atomizing nozzle 41. At the same time, the heater 31 and the heating wire 32 are energized and heated, heating the cotton core 33 inside the heating wire 32. The atomizing liquid inside the cotton core 33 is atomized and sprayed out from the atomizing nozzle 41. When the heater 31 is heated, the sealing rubber ring 34 deforms due to the heat. The memory metal ring 35 inside expands due to heat to compensate for the thermal deformation of the sealing rubber ring 34, ensuring the sealing effect of the electronic cigarette when it is used.
[0046] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
