Description

Technical Field

[0001] This utility model relates to the field of atomizing equipment, and more particularly to an aerosol generator. Background Technology

[0002] Existing aerosol generators mainly consist of two parts: an atomizing component and a power supply component. The atomizing component typically uses a heating wire or heating tube. The atomizing agent flows into the heating wire or heating tube and is heated, forming a high-temperature gaseous atomizing agent. Under pressure, external cooling gas enters the aerosol generator and mixes with the high-temperature gaseous atomizing agent. The high-temperature gaseous atomizing agent condenses rapidly upon contact with the external cooling gas, forming a mist. The power supply component provides power to the atomizing device. In existing aerosol generators, the atomizing component and power supply component are usually fixed together and cannot be disassembled. Furthermore, the heating device and liquid storage tank of the atomizing component are usually located together, which can easily lead to atomizing agent leakage after prolonged use. Utility Model Content

[0003] In view of the above, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an aerosol generator that is easy to disassemble and has good sealing properties, effectively preventing atomizing agent leakage.

[0004] This utility model provides an aerosol generator, including an atomizing component for heating an atomizing agent and a power supply component for providing power to the atomizing component. The atomizing component includes a substrate, a liquid storage tank for storing the atomizing agent, and a heating device. A slot is provided at one edge of the substrate, and a hook is provided on the corresponding side wall of the power supply component. The hook can be engaged with the slot to fix the atomizing component to the power supply component. The liquid storage tank includes a base plate with a flow guide groove. The heating device includes a base with a drainage channel communicating with the flow guide groove. The atomizing agent can flow into the drainage channel through the flow guide groove and thus enter the heating device.

[0005] Preferably, the substrate is provided with a vent hole, the base is provided with a hollow air guide column communicating with the vent hole, and the power supply component includes a top plate. The top plate is provided with an air intake channel communicating with the vent hole.

[0006] Preferably, the heating device further includes a positive electrode connecting plate and a negative electrode connecting plate fixed on the base. The base plate is provided with two positive electrode holes and two negative electrode holes. The bottom of the base is provided with a positive electrode plate electrically connected to the positive electrode connecting plate and a negative electrode plate electrically connected to the negative electrode connecting plate. The top plate is provided with two positive electrode posts and two negative electrode posts. The positive electrode posts can pass through the positive electrode holes and be electrically connected to the positive electrode plate. The negative electrode posts can pass through the negative electrode holes and be electrically connected to the negative electrode plate.

[0007] Preferably, the base is further provided with two adsorption holes that are respectively connected to the guide groove. The heating device also includes a heating element and an oil-drawing element. The heating element is connected to the positive electrode connecting plate and the negative electrode connecting plate on both sides and is located directly above the air guide column. The oil-drawing element fills the adsorption holes and the area around the heating element. The oil-drawing element is used to adsorb the atomizing agent in the guide groove to the heating element.

[0008] Preferably, the heating device further includes an atomizing hood, which has an atomizing chamber and a mist outlet channel located at the top of the atomizing chamber. The heating element is housed in the atomizing chamber, and the atomizing agent is heated and atomized in the atomizing chamber by the heating element and can be discharged from the mist outlet channel.

[0009] Preferably, the substrate is provided with a receiving groove, one end of which is provided with an oil filling port, the bottom plate is provided with a groove, and the groove is provided with a through hole, which is connected to the oil filling port, and the atomizing agent is added to the liquid storage tank through the oil filling port and the through hole.

[0010] Preferably, the groove is further provided with two permeation holes, which are respectively connected to the guide groove, so that the atomizing agent can enter the guide groove through the permeation holes.

[0011] Preferably, the top of the liquid storage tank is provided with an air inlet. When the atomizing agent inside the liquid storage tank enters the heating device through the guide channel and is heated and atomized, outside air can enter the liquid storage tank through the air inlet to balance the air pressure inside the liquid storage tank, thereby ensuring that the atomizing agent flows smoothly into the guide channel.

[0012] Preferably, a mounting plate protrudes from one side of the liquid storage tank, the mounting plate is provided with a mounting hole, the base is accommodated in the mounting hole, and two sealing members are sleeved between the mounting plate and the base to prevent the atomizing agent from leaking.

The protective cover has a clearance hole communicating with the mist outlet channel and a notch communicating with the air inlet. The protective cover also includes a protective sleeve, which can be snapped into the clearance hole and the notch to cover the mist outlet channel and the air inlet.

[0014] The aerosol generator provided by this invention features a detachable design for the atomizing component and the power supply component, allowing for easy disassembly, cleaning of the atomizing component, and refilling of the atomizing agent. Furthermore, the aerosol generator separates the heating device from the liquid storage tank, and the mist outlet channel from the liquid storage tank, effectively preventing atomizing agent leakage. Simultaneously, as the atomizing agent in the liquid storage tank is consumed, external gas can enter the liquid storage tank through the air inlet to balance the air pressure within the liquid storage tank, ensuring that the atomizing agent flows smoothly into the heating device. Therefore, the aerosol generator provided by this invention can provide a sustainable aerosol supply with excellent atomization effect. Attached Figure Description

[0036] This utility model provides an aerosol generator 100. The aerosol generator 100 according to an embodiment of this utility model is described below with reference to the accompanying drawings.

[0037] Please see Figure 1 The aerosol generator 100 includes an atomizing component 10 and a power supply component 60. The atomizing component 10 is used to heat the atomizing agent, and the power supply component 60 is used to provide power to the atomizing component 10.

[0038] Please see Figures 1 to 3 The atomizing assembly 10 includes a substrate 20, a liquid storage tank 30 fixed on the substrate 20, a heating device 40, and a protective cover 50. The substrate 20 has a receiving groove 21, with a filling port 211 at one end, through which the atomizing agent can enter the liquid storage tank 30. The substrate 20 also has a cover plate 215, which is housed within the receiving groove 21 and covers the filling port 211 to prevent leakage of the atomizing agent from the liquid storage tank 30.

[0039] Please see Figure 3 The substrate 20 has a vent 22, through which external cooling air enters the heating device 40 and cools the atomizing agent in a high-temperature gaseous state inside the heating device 40. The substrate 20 has at least one positive electrode hole 23 and at least one negative electrode hole 24 around the vent 22. The power supply component 60 can pass through the positive electrode hole 23 and the negative electrode hole 24 to electrically connect with the positive and negative electrodes of the heating device 40, thereby providing power to the atomizing component 10. In this embodiment, the substrate 20 has two positive electrode holes 23 and two negative electrode holes 24 to enhance power supply stability. Preferably, the two positive electrode holes 23 are closer to the vent 22 than the two negative electrode holes 24.

[0040] The substrate 20 is also provided with a plurality of fixing holes 25 around its perimeter. A plurality of fasteners 251 can pass through the fixing holes 25 and be inserted into the liquid storage tank 30, thereby fixing the liquid storage tank 30 to the substrate 20 together. A slot 26 is provided on one side edge of the substrate 20. The hook of the power supply component 60 can be engaged in the slot 26 to fix the atomizing component 10 to the power supply component 60 together.

[0041] Please see Figures 2 to 6The liquid storage tank 30 is used to store the atomizing agent. A base plate 31 is provided at its bottom, and the base plate 31 has a groove 32. The groove 32 has a through hole 321 and two permeation holes 322. The through hole 321 is connected to the filler port 211, allowing the atomizing agent to enter the liquid storage tank 30 through the filler port 211 and the through hole 321. Two guide grooves 33 are also provided at the bottom end of the base plate 31, with one end of each guide groove 33 connected to one of the two permeation holes 322, allowing the atomizing agent to flow into the guide grooves 33 through the permeation holes 322. A mounting plate 34 protrudes from one side of the liquid storage tank 30, and the mounting plate 34 has mounting holes 341. The heating device 40 can pass through the mounting holes 341 and be fixed to the base plate 20. Two limiting holes 35 are also provided at the top of the liquid storage tank 30 for fixing the protective cover 50. The top of the liquid storage tank 30 is provided with an air inlet 36. When the atomizing agent inside the liquid storage tank 30 enters the heating device 40 through the guide channel 33 and is heated and atomized, outside air can enter the liquid storage tank 30 through the air inlet 36 to balance the air pressure inside the liquid storage tank 30, thereby ensuring that the atomizing agent flows smoothly into the guide channel 33.

[0042] The heating device 40 includes a base 41, a positive electrode connecting plate 42, a negative electrode connecting plate 43, a heating element 44 for heating the atomizing agent, and an atomizing cover 48. The atomizing agent can be discharged from the atomizing cover 48 after being heated and atomized by the heating element 44.

[0043] A hollow air guide column 411 is disposed in the middle of the base 41, and the air guide column 411 is connected to the vent hole 22 of the substrate 20. A positive electrode plate 412 and a negative electrode plate 413 are disposed around the air guide column 411 at the bottom of the base 41. The positive electrode plate 412 is electrically connected to the positive electrode connecting plate 42, and the negative electrode plate 413 is electrically connected to the negative electrode connecting plate 43. In this embodiment, the positive electrode plate 412 is located in the inner ring, and the negative electrode plate 413 is located in the outer ring. Two flow channels 414 are disposed on the side of the base 41 near the bottom plate 31, which are respectively connected to the flow guide channel 33. Two adsorption holes 415 are disposed on the top of the base 41, which are respectively connected to the flow guide channel 414. The atomizing agent can enter the adsorption holes 415 through the flow guide channel 33 and the flow channel 414.

[0044] Preferably, the base 41 is accommodated in the mounting hole 341, and two sealing members 45 are sleeved between the mounting plate 34 and the base 41 to prevent the atomizing agent from leaking.

[0045] The positive electrode connecting plate 42 and the negative electrode connecting plate 43 are respectively fixed to the top two ends of the base 41. The heating element 44 is connected to the positive electrode connecting plate 42 and the negative electrode connecting plate 43 on both sides and is located directly above the air guide column 411. The two ends of the heating element 44 are close to the two adsorption holes 415. The heating element 142 can heat and atomize the atomizing agent. In this embodiment, the heating element 44 can be made of a metal with good heat resistance. Specifically, the material of the heating element 44 can be stainless steel, nickel alloy, or tungsten wire. The shape of the heating element 44 can be designed as one or more of the following shapes: spiral, tubular, mesh, and sheet, depending on the actual situation.

[0046] In this embodiment, the heating device 40 further includes an oil-guiding element (not shown in the figure). The oil-guiding element 416 fills the area around the adsorption hole 415 and the heating element 44. The oil-guiding element can be made of a flexible fiber fabric material with good temperature resistance or a solid material with micropores, thereby allowing the atomizing agent to permeate from the more humid side (i.e., the side of the drainage channel 414) to the drier side (i.e., the side of the heating element 44) through capillary action, thus facilitating the heating element 44 to heat the atomizing agent. Specifically, the flexible fabric material can be cotton, glass fiber, asbestos, etc., and the solid material with micropores can be porous ceramics, diatomaceous earth, gypsum, cement, etc.

[0047] The atomizing cover 48 is provided with an atomizing chamber 481 and a mist outlet channel 482 located at the top of the atomizing chamber 481. The heating element 44 is housed in the atomizing chamber 481. The atomizing agent is heated and atomized by the heating element 44 in the atomizing chamber 481 and can be discharged from the mist outlet channel 482. In this embodiment, the inner wall of the atomizing chamber 481 is approximately frustum-shaped, and the inner wall of the mist outlet channel 482 is approximately cylindrical. The inner diameter of the mist outlet channel 482 is smaller than the top diameter of the atomizing chamber 481, and a baffle is provided at its bottom protruding into the atomizing chamber 481. This design prevents the atomizing agent in the atomizing chamber 481 from being sprayed out due to insufficient heating. The atomizing cover 48 and the base 41 are connected together by a threaded connection. Specifically, in this embodiment, the inner wall of the atomizing cover 48 is provided with a first thread, and the base 41 is provided with a second thread at a corresponding position. The first thread and the second thread mesh with each other to connect the atomizing cover 48 and the base 41 together.

[0048] Please see Figures 2 to 6The protective cover 50 is fitted onto the atomizing cover 48. The protective cover 50 has several heat dissipation grooves 51 to quickly dissipate the heat generated by the heating device 40. Two limiting members 52 pass through the protective cover 50 and are inserted into the limiting holes 35 to fix the protective cover 50 to the liquid storage tank 30. The protective cover 50 also has a clearance hole 53 communicating with the mist outlet channel 482 and a notch 54 communicating with the air inlet 36. The protective cover 50 includes a protective sleeve 55, which can be snapped into the clearance hole 53 and the notch 54 to cover the mist outlet channel 482 and the air inlet 36.

[0049] Please see Figure 1 and Figure 7 The power supply assembly 60 includes a top plate 61 with an air intake channel 611 connected to the vent 22. An air blowing device (not shown) is installed within the power supply assembly 60. This device blows external cooling air towards the air intake channel 611 and through the vent 22 and the air guide column 411 towards the heating device 40. At least one positive electrode post 612 and at least one negative electrode post 613 are arranged around the top plate 61 near the air intake channel 611. The positive electrode post 612 passes through the positive electrode hole 23 and is electrically connected to the positive electrode plate 412. The negative electrode post 613 passes through the negative electrode hole 24 and is electrically connected to the negative electrode plate 413. In this embodiment, two positive terminals 612 and two negative terminals 613 are provided on the top plate 61 to enhance power supply stability. Preferably, the two positive terminals 612 are closer to the air intake channel 611 than the two negative terminals 613. It is understood that the power supply assembly 60 contains a power source, and the positive and negative terminals of the power source are electrically connected to the positive terminals 612 and the negative terminals 613, respectively. A switch is provided on one side wall of the power supply assembly 60; turning on the switch supplies power to the atomizing assembly 10, and turning off the switch stops supplying power to the atomizing assembly 10.

[0050] A hook 62 is provided on one side wall of the power supply component 60. The hook 62 can slide between a closed position and an open position. When the hook 62 is in the closed position, it engages with the slot 26, thereby fixing the atomizing component 10 to the power supply component 60. When the hook 62 is in the open position, it disengages from the slot 26, and the atomizing component 10 can be detached from the power supply component 60.

[0051] When the aerosol generator 100 is needed, open the cover plate 215, inject the atomizing agent into the liquid storage tank 30 through the filler port 211, and then close the cover plate 215 to cover the filler port 211. Next, place the atomizing assembly 10 onto the top plate 61 of the power supply assembly 60, aligning the air guide column 411 with the air intake channel 611. The positive electrode post 612 passes through the positive electrode hole 23 and is electrically connected to the positive electrode plate 412, and the negative electrode post 613 passes through the negative electrode hole 24 and is electrically connected to the negative electrode plate 413. Then, slide the hook 62 to the closed position so that the hook 62 engages with the slot 26 of the substrate 20, thereby completing the assembly of the atomizing assembly 10 and the power supply assembly 60. At this time, the atomizing agent in the storage tank 30 flows from the permeation hole 322 into the guide channel 33 under the action of gravity, and flows along the guide channel 33 to the diversion channel 414. Subsequently, it is adsorbed by the oil guide element 46 in the adsorption hole 415 from the diversion channel 414 to the vicinity of the heating element 44. At the same time, the protective cover 55 is opened, so that the air inlet 36 and the mist outlet channel 482 are connected to the outside. Outside gas can enter the storage tank 30 at any time through the air inlet 36 to balance the internal air pressure of the storage tank 30, thereby ensuring that the atomizing agent flows smoothly into the heating device 40.

[0052] After the atomizing component 10 and the power supply component 60 are assembled, the switch is turned on, and the heating device 40 starts working to heat and atomize the atomizing agent near the heating element 44. The heated and atomized atomizing agent fills the atomizing chamber 481. The air blowing device of the power supply component 60 blows external cooling air towards the air inlet channel 611. The cooling air passes through the air guide column 411 and the vent 22 and then blows towards the heating element 44, cooling the atomizing agent in a high-temperature gaseous state inside the atomizing chamber 481. That is, the atomizing agent undergoes a "liquid-gas-liquid" physical change inside the atomizing chamber 481 to form mist. At this time, driven by the cooling air, the vaporized mist is discharged from the mist outlet channel 482, thus successfully completing the mist-making process.

[0053] The aerosol generator 100 provided by this utility model adopts a detachable design for the atomizing component 10 and the power supply component 60, which can facilitate the disassembly, cleaning of the atomizing component 10 and the addition of atomizing agent. In addition, the aerosol generator 100 also separates the heating device 40 from the liquid storage tank 30, and the mist outlet channel 482 from the liquid storage tank 30, thereby effectively preventing atomizing agent leakage. Furthermore, the oil supply scheme of the aerosol generator 100 of this utility model adopts the capillary principle. The atomizing agent in the liquid storage tank 30 continuously seeps into the heating device 40 under the attraction of the oil inlet 46, continuously repeating the "liquid-gas-liquid" atomization process, ensuring a continuous supply of atomizing agent during the atomization process. Simultaneously, as the atomizing agent in the liquid storage tank 30 is consumed, external gas can enter the liquid storage tank 30 through the air inlet 36 to balance the air pressure inside the liquid storage tank 30, thereby ensuring that the atomizing agent flows smoothly into the heating device 40. Therefore, the aerosol generator 100 provided by this utility model can provide a sustainable aerosol with good atomization effect.
