[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 4The present invention discloses an electronic atomization device, which includes a body 100 and a sealing cover 200. The body 100 includes a nozzle 1, a shell 2, a liquid storage component 3, an atomizing core 4, a bottom blocking component 5, a controller 6, a battery 7 and a liquid supply switch 8. The nozzle 1 is connected to the shell 2, and the nozzle 1 is provided with a mist outlet 11. The bottom wall of the shell 2 is provided with an air inlet 21, and the air inlet 21 is used to introduce external air into the shell 2.

[0024] The liquid storage assembly 3 is located in the housing 2, and includes a second vent pipe 31, a liquid storage sleeve 32, a sealing top seat 33, a sealing base 34 and an isolation ring 35. The second vent pipe 31 is inserted in the liquid storage sleeve 32, and an atomizing chamber 311 is formed in the second vent pipe 31. The atomizing chamber 311 passes through the top wall of the liquid storage assembly 3 and is connected to the mist outlet hole 11. A liquid guide hole 310 is provided at the cavity wall of the atomizing chamber 311. The second vent pipe 31, the liquid storage sleeve 32 and the isolation ring 35 form a first liquid storage chamber 313 and a second liquid storage chamber 314, both of which are used to store vapor mist generating liquid. A drainage hole 315 is provided at the cavity wall of the second liquid storage chamber 314.

[0025] The vapor generating liquid may include propylene glycol, glycerol, flavors and fragrances, etc. It is understandable that as long as vapor is formed after being heated and atomized, its chemical composition is not specifically limited here. The liquid guide hole 310 is connected to the first liquid storage chamber 313, and the vapor generating liquid flows out from the liquid guide hole 310. The sealing top seat 33 is covered on the top of the liquid storage sleeve 32 and is sleeved on the second ventilation pipe 31, and the atomization chamber 311 passes through the sealing top seat 33. The sealing base 34 is covered on the second end of the liquid storage sleeve 32 and inserted into the second liquid storage chamber 314.

[0026] The atomizing core 4 is located in the atomizing chamber 311 and covers the liquid guide hole 310, which is used to atomize the vapor mist generating liquid. In the present embodiment, the atomizing core 4 includes a liquid guide cotton tube 41, a heating wire 42 and a plurality of first air bags 43, and the liquid guide cotton tube 41 is located in the atomizing chamber 311. An atomizing hole 411 is provided in the liquid guide cotton tube 41, and the atomizing hole 411 passes through the end faces of both ends of the liquid guide cotton tube 41. It is understandable that the liquid guide cotton tube 41 can be formed by winding one or more pieces of cotton cloth. The heating wire 42 is electrically connected to the controller 6, which is wound in a columnar shape and attached to the cavity wall of the atomizing hole 411. The first air bag 43 is located in the liquid guide cotton tube 41, and is used to drive the vapor mist generating liquid or the receptor stimulant in the liquid guide cotton tube 41 to the heating wire 42 when it is heated and expanded. The first air bag 43 can be made of an elastic material such as inflatable rubber or latex.

[0027] Every two adjacent first airbags 43 are spaced apart from each other, and a plurality of first airbags 43 form a ring, and the distances from all first airbags 43 to the atomization hole 411 are equal. Therefore, when the heating wire 42 is heated, the first airbags 43 are heated and gradually expand, so that the liquid-guiding cotton is squeezed, and the vapor-generating liquid or the receptor stimulant in the liquid-guiding cotton tube 41 is driven to the heating wire 42, so that the heating wire 42 can be continuously replenished with the vapor-generating liquid.

[0028] The atomizer core 4 also includes a first protective sleeve 44 and a first liquid-blocking ring 45. The first protective sleeve 44 is inserted into the atomization hole 411. The heating wire 42 and the first protective sleeve 44 are located at different axial positions of the atomization hole 411. The first airbag 43 and the first protective sleeve 44 are located at the same radial position of the atomization hole 411. Therefore, when the first airbag 43 expands, the heating wire 42 is prevented from being squeezed and deformed, thereby affecting the resistance value of the heating wire 42. The first liquid-blocking ring 45 is covered at the upper end surface of the liquid-conducting cotton tube 41 and sleeved on the first protective sleeve 44, thereby avoiding the problem of excessive expansion of the first airbag 43, thereby generating liquid from the vapor mist in the liquid-conducting cotton tube 41.

[0029] The atomizing core 4 further includes a second protective sleeve 46, a second liquid blocking ring 47 and a plurality of second airbags 48. The second protective sleeve 46 is inserted into the atomizing hole 411. The heating wire 42 is located between the first protective sleeve 44 and the second protective sleeve 46. The second airbag 48 and the second protective sleeve 46 are located at the same radial position of the atomizing hole 411. The second protective sleeve 46 is located below the first protective sleeve 44. The second liquid blocking ring 47 is covered at the lower end surface of the liquid-conducting cotton tube 41 and sleeved on the second protective sleeve 46. The volume of the second airbag 48 is greater than that of the first airbag 43. Due to the effect of gravity, the saturation of the lower end of the liquid-conducting cotton tube 41 is often greater than that of the upper end, that is, the vapor mist generating liquid at the lower end of the liquid-conducting cotton tube 41 is more. Since the volume of the second airbag 48 is greater than that of the first airbag 43, the volume of the second airbag 48 expands more when heated, thereby replenishing more vapor mist generating liquid to the heating wire 42.

[0030] The bottom plugging assembly 5 is located at the end of the liquid storage assembly 3 facing away from the suction nozzle 1. The bottom plugging assembly 5 includes a first ventilation pipe 51, a first liquid storage cup 52, a first electric heating coil 53, a first piston 54 and a driving mechanism 55. The first ventilation pipe 51 is connected to the bottom wall of the liquid storage assembly 3. The first ventilation pipe 51 is provided with an air guide cavity 511, which is connected to the atomization cavity 311. The cavity wall of the air guide cavity 511 is provided with a liquid inlet hole 512. The first liquid storage cup 52 is provided with a first liquid storage tank 521 connected to the liquid inlet hole 512, and the first liquid storage tank 521 contains a reversible phase change gel.

[0031] It is understandable that the small molecular weight organic gelling agent self-assembles to obtain a three-dimensional network through non-covalent interactions such as hydrogen bonding, van der Waals forces, and electrostatic interactions, and the organic solvent molecules are captured and fixed to the three-dimensional network through interfacial forces to form a viscoelastic gel material. Due to its complex supramolecular structure, such a gel is called a supramolecular organic gel. The supramolecular organic gel is a non-glassy, ​​non-crystalline thermally reversible solid material, that is, it is a reversible phase change gel. The reversible phase change gel of this embodiment is a supramolecular organic gel. Preferably, the reversible phase change gel is a sugar-based gel containing an aromatic ring. Among them, the sugar-based gel containing an aromatic ring is a material sold on the market, and its specific structure is not repeated here.

[0032] The first electric heating coil 53 is sleeved on the first liquid storage cup 52 and connected to the controller 6. When the controller 6 receives more than 3 inhalation signals formed by the user inhaling within 1 second, the controller 6 controls the battery 7 to supply power to the first electric heating coil 53 so that the first electric heating coil 53 generates heat. The first piston 54 is movably disposed in the first liquid storage tank 521 and can move up and down along the first liquid storage tank 521. The driving mechanism 55 is connected to the first piston 54 and is used to drive the first piston 54 to move. The sealing cover 200 includes a cover body 201 and a push rod 202, and the push rod 202 is connected to the cover body 201.

[0033] The electronic atomization device of the present invention includes a cover state and an open cover state. In the cover state, the cover body 201 is covered on the suction nozzle 1, the push rod 202 penetrates the atomization chamber 311 and the air guide chamber 511 and abuts against the driving mechanism 55, and the first piston 54 squeezes the reversible phase change gel, the reversible phase change gel is in a gel state, and at least part of the reversible phase change gel is located in the gap between the air guide chamber 511 and the push rod 202. In the open cover state, the first electric heating coil 53 generates heat to change the reversible phase change gel from a gel state to a liquid state, the sealing cover 200 is separated from the suction nozzle 1, the driving mechanism 55 drives the first piston 54 to reset, and at least part of the reversible phase change gel in the air guide chamber 511 flows back to the first liquid storage tank 521 through the liquid inlet hole 512.

[0034] Specifically, the driving mechanism 55 includes a first connecting rod 551, a support plate 552 and a first elastic member 553. The first end of the first connecting rod 551 penetrates the bottom wall of the first liquid storage tank 521 and is connected to the first piston 54. The second end of the first connecting rod 551 is connected to the support plate 552. The first elastic member 553 elastically abuts against the support plate 552, and is used to drive the support plate 552 so that the support plate 552 pushes the first connecting rod 551 and the first piston 54 to move toward the nozzle 1, so that at least part of the reversible phase change gel in the air guide cavity 511 flows back into the first liquid storage tank 521 through the liquid inlet hole 512, so as to prevent the reversible phase change gel from falling randomly. In the capping state, the push rod 202 abuts against the support plate 552, so that the support plate 552 squeezes the first elastic member 553, and the first elastic member 553 is in a compressed state; in the uncapping state, the push rod 202 is released from the abutment with the support plate 552, and the first elastic member 553 is reset. The driving mechanism 55 has the advantages of being easy to control and assemble.

[0035] The driving mechanism 55 further includes a first guide column 554 and a fixing plate 555. The first guide column 554 is fixed on the fixing plate 555. The support plate 552 is movably sleeved on the first guide column 554. The fixing plate 555 is located on the side of the support plate 552 facing away from the first vent pipe 51. The first end of the first elastic member 553 abuts against the support plate 552, and the second end of the first elastic member 553 abuts against the fixing plate 555. The first guide column 554 is used for guidance, thereby preventing the support plate 552 from shaking left and right, thereby improving reliability.

[0036] The driving mechanism 55 further includes a first positioning tube 556, which is fixed on the fixing plate 555 and located between the fixing plate 555 and the supporting plate 552. The first end of the first elastic member 553 is located outside the first positioning tube 556, and the second end of the first elastic member 553 is located inside the first positioning tube 556. By positioning the first elastic member 553 through the first positioning tube 556, it is unnecessary to fix the first elastic member 553, thereby reducing the production process and improving the assembly efficiency.

[0037] The driving mechanism 55 also includes a bracket 557 and a liquid blocking tube 558, the liquid storage assembly 3 is fixed on the bracket 557, and the fixed plate 555 is fixed on the bracket 557 and is located in the space formed by the bracket 557 and the liquid storage assembly 3. The liquid blocking tube 558 is fixed on the fixed plate 555 and is located between the support plate 552 and the fixed plate 555. When in the capping state, the support plate 552 is covered on the first end face of the liquid blocking tube 558, thereby further improving the sealing performance. When in the uncapping state, the first end of the liquid blocking tube 558 is communicated with the air guide cavity 511, and the second end of the liquid blocking tube 558 is communicated with the outside of the housing 2. The leaked vapor mist generating liquid and the reversible phase change gel are blocked by the liquid blocking tube 558, thereby preventing the vapor mist generating liquid and the reversible phase change gel from leaking to the outside of the housing 2.

[0038] The support plate 552 is provided with an air guide hole 5521, and the orthographic projection of the air guide hole 5521 on the fixed plate 555 is arranged at a distance from the liquid blocking tube 558. When the cover is opened, the external air flows into the liquid blocking tube 558 through the air inlet hole 21, and then enters the air guide cavity 511 through the air guide hole 5521. The first ventilation tube 51 is coaxially arranged with the liquid blocking tube 558, and the diameter of the first ventilation tube 51 is larger than the diameter of the liquid blocking tube 558. Therefore, the vapor mist generating liquid and the reversible phase change gel can be prevented from flowing into the liquid blocking tube 558 and leaking out of the housing 2.

[0039] The driving mechanism 55 further includes a second liquid storage cup 5591, a second electric heating coil 5592, a second piston 5593, a second connecting rod 5594, a second elastic member 5595, a second positioning tube 5596 and a second guide column 5597. The second liquid storage cup 5591 and the first liquid storage cup 52 are located on opposite sides of the first ventilation tube 51 and are connected to the air guide cavity 511. The second liquid storage cup 5591 contains a reversible phase change gel. The second electric heating coil 5592 is sleeved outside the second liquid storage cup 5591 and is electrically connected to the controller 6. The second piston 5593 is movably arranged in the second liquid storage cup 5591, and the second connecting rod 5594 is connected to the second piston 5593 and the support plate 552. The second elastic member 5595 is located between the fixing plate 555 and the support plate 552, and abuts against the support plate 552. The second positioning tube 5596 is sleeved on the second elastic member 5595, and the support plate 552 is movably sleeved on the second guide column 5597. In this embodiment, the first elastic member 553 and the second elastic member 5595 are both springs.

[0040] The electronic atomization device of the present invention further includes a first sealing ring 91 and a second sealing ring 92. A first drainage hole 5211 is provided at the wall of the first liquid storage tank 521. The first sealing ring 91 is installed at the first drainage hole 5211 and seals the edge of one liquid inlet hole 512. Similarly, a second drainage hole (not shown) is provided at the second liquid storage cup 5591. The second sealing ring 92 is installed at the second drainage hole and seals the edge of another liquid inlet hole 512 to prevent leakage of the reversible phase change gel.

[0041] The electronic atomization device of the present invention also includes an elastic sealing sheet 93 and an air regulating sheet 94. The elastic sealing sheet 93 is located on the side of the bracket 557 facing away from the liquid storage component 3. The elastic sealing sheet 93 can be a silicone sheet or a rubber sheet. The air regulating sheet 94 is movably arranged between the elastic sealing sheet 93 and the bottom wall of the shell 2, and abuts against the elastic sealing sheet 93. The air regulating sheet 94 is provided with an air regulating hole 941. In the closed state, the air inlet 21 and the air regulating hole 941 are staggered to separate the inside and outside of the shell 2, thereby further enhancing the sealing. In the open state, the air inlet 21 is connected to the atomization chamber 311 through the air regulating hole 941, and the air intake volume can be adjusted by adjusting the overlapping area of ​​the air inlet 21 and the air regulating hole 941.

[0042] The present invention cooperates with the sealing cover 200 and the main body 100. Before air transportation, the controller 6 controls the first electric heating coil 53 to heat for a preset time. The first electric heating coil 53 heats and melts the reversible phase change gel. After the sealing cover 200 is covered on the suction nozzle 1, the present invention is in a capped state. In the capped state, the push rod 202 penetrates the atomization chamber 311 and the air guide chamber 511 and abuts against the driving mechanism 55. The first piston 54 squeezes the reversible phase change gel. After cooling, the reversible phase change gel is in a gel state, and at least part of the reversible phase change gel is located in the gap between the air guide chamber 511 and the push rod 202, thereby sealing the gap between the air guide chamber 511 and the push rod 202, so that the vapor generated liquid in the liquid storage component 3 is not easy to leak out.

[0043] When the user needs to use it, the controller 6 controls the first electric heating coil 53 to heat for a preset time, the first electric heating coil 53 heats and melts the reversible phase change gel, and then removes the sealing cover 200 to put the electronic atomization device in the second state. In the open cover state, the driving mechanism 55 drives the first piston 54 to reset, and at least part of the reversible phase change gel in the air guide cavity 511 flows back to the first liquid storage tank 521 through the liquid inlet hole 512. Therefore, not only can the leakage of the vapor generated liquid be prevented during air transportation, but also the air pressure of the atomization cavity 311 decreases during the process of pulling out the push rod 202, so that the vapor generated liquid can be quickly replenished to the atomization core 4, which is convenient for users to use.

[0044] The liquid supply switch 8 includes a liquid discharge pipe 81, a guide rod 82, a first magnetic member 83, and a second magnetic member 84. The liquid discharge pipe 81 is located in the first liquid storage chamber 313 and connected to the wall of the first liquid storage chamber 313. The liquid discharge pipe 81 is used to prevent the vapor production liquid in the first liquid storage chamber 313 from flowing into the second liquid storage chamber 314. The first end of the liquid discharge hole 315 is connected to the first end of the liquid discharge pipe 81, and the second end of the liquid discharge hole 315 is connected to the second liquid storage chamber 314, so that the vapor production liquid in the second liquid storage chamber 314 flows into the first liquid storage chamber 313 through the liquid discharge hole 315 and the liquid discharge pipe 81 when the electronic atomization device is inverted.

[0045] The guide rod 82 is coaxially arranged with the discharge pipe 81, the first end of the guide rod 82 is located inside the discharge pipe 81, and the second end of the guide rod 82 is located outside the discharge pipe 81. The first magnetic member 83 is movably sleeved on the guide rod 82, and the first magnetic member 83 is guided by the guide rod 82, so that the first magnetic member 83 is aligned with the pipe mouth of the discharge pipe 81 to prevent deviation caused by swinging and the like. The second magnetic member 84 is connected to the guide rod 82 and is located on the side of the first magnetic member 83 facing away from the discharge pipe 81. In this embodiment, the second magnetic member 84 is fixed to the end of the guide rod 82, so it is not easy to fall off.

[0046] The electronic atomization device of the present invention includes an upright state and an inverted state. In the upright state, the nozzle 1 faces upward, the first magnetic member 83 is covered on the nozzle of the liquid discharge pipe 81, the inner cavity of the liquid discharge pipe 81 is isolated from the first liquid storage cavity 313, the first magnetic member 83 and the second magnetic member 84 are magnetically repelled, and the first magnetic member 83 and the second magnetic member 84 are separated by a first preset distance. At this time, under the action of the magnetic force of the second magnetic member 84 and the gravity of the first magnetic member 83, the first magnetic member 83 tightly seals the nozzle of the liquid discharge pipe 81. In this embodiment, in the upright state, the magnetic force between the first magnetic member 83 and the second magnetic member 84 is not less than the gravity of the first magnetic member 83, the first magnetic member 83 and the second magnetic member 84 are coaxially arranged, and the first magnetic member 83 and the second magnetic member 84 are both magnets. It can be understood that as long as it can generate magnetic force, its material is not specifically limited here. The height of the first liquid storage chamber 313 is higher than that of the second liquid storage chamber 314 , so it is not easy to cause the problem that the vapor generating liquid in the second liquid storage chamber 314 flows into the first liquid storage chamber 313 at will.

[0047] When the vapor generating liquid in the first liquid storage chamber 313 is exhausted, the user turns the electronic atomization device upside down. Due to the gravity of the first magnetic member 83 and the vapor generating liquid, the first magnetic member 83 moves in the direction of the second magnetic member 84 until the force is balanced and the device is stationary. At this time, the electronic atomization device enters an inverted state. In the inverted state, the first magnetic member 83 and the drain pipe 81 are spaced apart, and the first magnetic member 83 and the second magnetic member 84 are separated by a second preset distance, which is smaller than the first preset distance. The inner cavity of the drain pipe 81 is connected to the first liquid storage chamber 313 and the second liquid storage chamber 314. The vapor generating liquid in the second liquid storage chamber 314 flows into the first liquid storage chamber 313 through the drain hole 315 and the drain pipe 81, so that the vapor generating liquid can be replenished to the first liquid storage chamber 313 through the second liquid storage chamber 314. When the refilling is completed, the electronic atomization device can be placed upright and used normally. Therefore, the user does not need to push, pull or press when refilling the vapor generating liquid, which is not only convenient for the user to use, but also has good sealing performance to avoid leakage. It can be understood that the second preset distance can be set as needed, and the distance can be 0.

[0048] The controller 6 and the battery 7 are both located in the housing 2. The controller 6 is electrically connected to the battery 7 so that when the user inhales the vapor, the controller 6 controls the battery 7 to power the atomizer core 4. Since the magnetic force between the first magnetic member 83 and the second magnetic member 84 is not less than the gravity of the first magnetic member 83. Therefore, when the electronic atomization device enters an inverted state, and the vapor generating liquid in the second liquid storage chamber 314 flows into the first liquid storage chamber 313 and generates buoyancy on the first magnetic member 83, the distance between the first magnetic member 83 and the discharge pipe 81 gradually decreases, thereby not only facilitating the vapor generating liquid in the second liquid storage chamber 314 to flow into the first liquid storage chamber 313, but also better preventing the vapor generating liquid in the first liquid storage chamber 313 from flowing back into the second liquid storage chamber 314.

[0049] In summary, the present invention cleverly cooperates with the liquid storage component 3 and the liquid supply switch 8. The liquid storage component 3 is provided with a first liquid storage chamber 313 and a second liquid storage chamber 314, and the atomization chamber 311 passes through the top wall of the liquid storage component 3; the liquid supply switch 8 includes a discharge pipe 81, a guide rod 82, a first magnetic component 83 and a second magnetic component 84 that cooperate with each other. When in an upright state, through the repulsive force of the first magnetic component 83 and the magnetic gravity of the second magnetic component 84, the first magnetic component 83 is firmly covered on the pipe mouth of the discharge pipe 81 to seal the second liquid storage chamber 314, so that the first liquid storage chamber 313 and the second liquid storage chamber 314 are isolated from each other. When the vapor generating liquid in the first liquid storage chamber 313 is about to be exhausted, the electronic atomization device is inverted to make the electronic atomization device enter an inverted state. In the inverted state, the gravity of the second magnetic member 84 and the gravity of the vapor generating liquid in the second liquid storage chamber 314 cause the first magnetic member 83 and the drain pipe 81 to be spaced apart. At this time, the vapor generating liquid in the second liquid storage chamber 314 flows into the first liquid storage chamber 313 through the drain hole and the drain pipe 81, so the vapor generating liquid in the first liquid storage chamber 313 can be automatically replenished. Therefore, the amount of vapor generating liquid stored as a whole is large, avoiding frequent replacement of the atomization core, which is not only convenient for users to use, but also has good sealing performance and avoids leakage, and is more environmentally friendly.
