Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization generating device. Background Technology

[0002] Electronic cigarettes generally include an e-liquid reservoir containing e-liquid, a mouthpiece at the top, and a battery assembly and control assembly at the bottom. An air duct is also installed within the reservoir, with one end connected to the mouthpiece and the other end connected to an air inlet that allows air to pass through. An atomizing assembly is installed within the air duct, with an e-liquid inlet connected to the reservoir. The atomizing assembly corresponds to this inlet and includes wicking material and a heating wire. The heating wire is bent into a spiral shape, and the wicking material covers the outside of the spiral heating wire. E-liquid flows through the inlet to the wicking material. The heating wire is connected to the control assembly, which in turn is connected to the battery assembly. The control assembly controls the current or voltage flowing from the battery assembly to the heating wire, thereby controlling the heating power of the heating wire.

[0003] During inhalation, the heating wire generates heat, which heats the e-liquid inside the wicking cotton into a gaseous state. Outside air flows in through the air inlet, flows upward over the heating wire, carries away the gaseous e-liquid, and flows out from the mouthpiece. Due to the air flow, the air pressure inside the wicking cotton decreases, creating a pressure difference between the air pressure outside and inside the wicking cotton. E-liquid in the reservoir can continuously enter the wicking cotton, maintaining a dynamic balance.

[0004] Under normal pressure, because the air pressure inside and outside the wicking cotton is equal, and due to the surface tension of the e-liquid itself, the e-liquid can be absorbed by the wicking cotton and will not flow out of the wicking cotton into the air tube. However, when the e-cigarette is transported or stored, if the environment in which the e-cigarette is located changes, the air pressure inside the wicking cotton may change. The inside of the wicking cotton needs to be consistent with the ambient air pressure, which causes the air pressure difference between the inside and outside of the wicking cotton to exceed a threshold. The e-liquid in the wicking cotton will then enter the air tube. When the e-liquid that has flowed out accumulates to a certain extent, the e-liquid will flow out from the air inlet along the air tube. Utility Model Content

[0033] the following Figure 1-6 This section will primarily describe the specific structure of the atomizing device (also known as an electronic cigarette). Please refer to [link / reference]. Figure 1-6 A vapor generator includes a housing 2, an upper housing 1 made of plastic, and a sealing element 21 made of silicone. A suction port 11 is formed at the top of the upper housing 2, facilitating connection with the mouth. An air inlet 21 extends from the top of the sealing element 21 downwards. A tube 22 connects the suction port and the air inlet 211. The upper housing 1, housing 2, sealing element 21, and tube 22 together form an oil reservoir. Specifically, the lower part of the upper housing 1, the inner surface of the housing 2, the upper surface of the sealing element 21, and the outer side of the tube 22 form an oil reservoir 6, which contains e-liquid. The e-liquid can be injected by first separating the upper housing 1 from the housing 2, injecting e-liquid from the upper part of the upper housing 1, and then reassembling the upper housing 1 onto the upper part of the housing 2 to achieve a seal between the upper housing 1 and the housing 2.

[0034] The atomizing device also includes a lower shell 5, which houses a power supply 51, a control board 53, and a bracket 52. The power supply 51 is connected to the control board 53, and the control board 53 is fixed to the bracket 52. Specifically, the upper part of the lower shell 5 is open. The power supply 51 is a battery or similar device and is installed in the bracket 52. The upper part of the bracket 52 is equipped with the control board 53, which is also equipped with a pressure sensor, such as a microphone. The control board 53 is fixed to the bracket 52 and is connected to the microphone. The control board 53 is also connected to the power supply 51 and is equipped with a light-emitting component, such as an LED. The control board 53 controls the output mode of the power supply 51, such as the output power, output voltage, and current. The bracket 52 is made of plastic material, but other materials can also be used.

[0035] The oil storage tank 6 is provided with an air inlet 211, a suction port 11, and a tube 22. One end of the tube 22 is connected to the air inlet 211, and the other end is connected to the suction port 11. The tube 22 is also provided with an oil inlet hole 221. The atomizing component 3 is disposed on the tube 22 and is located at the oil inlet hole 221. The atomizing component 3 includes oil-guiding cotton and a heating element. In this design, the heating element is a heating plate, which is bent into a cylindrical shape. The oil-guiding cotton covers the outside of the heating element. The heating element has two ends, which are used to connect to the positive and negative terminals of the power supply 51, respectively. The tube 22 is a steel pipe, or a high-temperature resistant plastic pipe can be used. E-liquid can flow into the oil-guiding cotton from the oil inlet hole 221. The oil-guiding cotton absorbs the e-liquid and the e-liquid is evenly distributed on the oil-guiding cotton.

[0036] The sealing assembly 4 includes a first sealing body 41 and a second sealing body 42. The first sealing body 41 is installed at the suction port 11 and is hollow. The second sealing body 42 is installed at the tube body 22. One end of the second sealing body 42 is inserted into the hollow first sealing body 41, and the second sealing body 42 compresses the first sealing body 41. The first sealing body 41 contacts the inner wall of the suction port 11, and the first sealing body 41 is compressed and expanded, tightly compressing the inner wall of the suction port 11. The other end of the second sealing body 42 abuts against the air inlet 211. The lower end of the second sealing body 42 abuts against the top of the sealed air inlet 211 for sealing purposes, or the second sealing body 42 can be inserted into the air inlet 211 to seal the air inlet 211.

[0037] Further, the first sealing body 41 includes a first operating part 411 and a first main body part 412. The first main body part 412 extends downward from the middle of the first operating part 411. The first operating part 411 covers the outer side of the suction port 11. The first main body part 412 is assembled to the suction port 11 and is hollow. In this design, the first sealing body 41 and the second sealing body 42 are separate designs, which facilitates the molding of each and the assembly and separation between them. The first sealing body 41 is made of silicone material, and the second sealing body 42 is made of plastic material. The second sealing body 42 can also be made of stainless steel material. The shape of the first sealing body 41 matches the suction port 11. The first operating part 411 can be divided into two parts: the upper part is located above the suction port 11 and can seal the upper part of the suction port 11, and the lower part is located below the suction port 11 and can seal the area outside the suction port 11.

[0038] A first receiving hole 413 is formed on the lower surface of the first main body 412, and a rib 414 protrudes from the inner wall of the first receiving hole 413. A groove 421 is formed on the upper outer surface of the second sealing body 42, and the rib 414 is fitted into the groove 421. The cooperation between the rib 414 and the groove 421 can prevent them from sliding against each other. The diameter of the top end of the second sealing body 42 is larger than that of the groove 421, which can prevent the first sealing body 41 and the second sealing body 42 from separating from each other during the process of pulling out the second sealing body 42. The first main body 412 is inserted into the suction port 11, which facilitates its installation and positioning, prevents misalignment during assembly, and also prevents its installation from being offset.

[0039] A first through hole 415 is formed on the top wall of the first receiving hole 413, extending upwards through the upper surface of the first main body 412. The upper end of the second sealing body 42 is exposed through the first through hole 415. The first through hole 415 allows observation of whether the second sealing body 42 is properly assembled and also serves to release excess airflow. When the second sealing body 42 is not assembled, air inside the tube 22 can flow upwards through the first receiving hole 413 and out through the first through hole 415.

[0040] The suction port 11 gradually tapers from top to bottom, and the first main body 412 also gradually tapers from top to bottom, which facilitates the installation of the first main body 412 from top to bottom and also makes it easy to pull it out of the suction port 11. This assembly can expel excess air from the tube 22, which facilitates the connection between the first main body 412 and the suction port 11 and avoids the situation where the air pressure inside the tube 22 is too high and the first main body 412 is easy to come out. The outer side of the first main body 412 is provided with a first sealing strip 416 that abuts against the inner wall of the suction port 11. The first sealing strip 416 is used to abut against the inner side of the suction port 11.

[0041] In another design, the lower end of the second sealing body 42 is inserted into the air inlet 211. An annular groove 422 is formed inwardly at the lower end of the second sealing body 42, encircling the side of the second sealing body 42 and extending downwards through the lower surface of the second sealing body 42. The upper surface of the annular groove 422 abuts against the upper end face of the air inlet 211. The diameter of the lower end of the second sealing body 42 is smaller than the diameter of the air inlet 211, allowing gas to flow through the gap between the lower end of the second sealing body 42 and the air inlet 211. However, because the upper surface of the annular groove 422 abuts against the upper end face of the air inlet 211, a seal exists between the annular groove 422 and its upper surface, effectively preventing gas from passing through the gap between them. In this design, the air inlet 211 can position the lower part of the second sealing body 42, preventing it from shifting, and also facilitates the insertion and removal of the second sealing body 42, making operation more convenient and faster.

[0042] The lower surface of the seal 21 has an upward-facing light-transmitting hole 212. The control board 53 is equipped with an LED, which is located below the light-transmitting hole 212. The seal 21 can be made of colorless transparent silicone to facilitate the passage of light. The light-transmitting hole 212 is a blind hole, and its top wall is not connected to the oil storage tank 6. Light can be emitted upward through the light-transmitting hole 212 to illuminate the oil storage tank 6, especially in low-light conditions, such as at night, allowing users to intuitively observe the e-liquid in the oil storage tank 6 and its usage status.

[0043] An air inlet 54 is provided at the bottom of the lower shell 5, and an air outlet 55 is provided on the bracket 52. The air outlet 55 is located below the air inlet 211. Outside air flows into the lower shell 5 through the air inlet 54, passes through the battery and the bracket, and flows out through the air outlet 55, reaching below the air inlet 211. A microphone assembly is also provided inside the lower shell 5. The microphone assembly is connected to the control board 53. The microphone assembly can sense changes in air pressure. When the air pressure inside the lower shell 5 changes, the microphone sends an electrical signal to the circuit board.

[0044] When the first sealing body 41 is inserted into the suction port 11 and the second sealing body 42 is inserted into the air inlet 211, both ends of the tube 22 are isolated from the outside air, allowing outside air to flow in and e-liquid in the oil storage tank 6 to flow out. In use, the first sealing body 41 and the second sealing body 42 are pulled out, and suction is drawn through the suction port 11. Outside air enters the lower shell 5 through the air inlet 54, flows out through the air outlet 55, enters the air inlet 211, flows upward through the lower end of the tube 22, and flows out from the suction port 11. The airflow flows through the lower shell 5, and the air pressure inside the lower shell 5 changes. The microphone sends an electrical signal to the circuit board, and the circuit board controls the power supply 51 to supply power to the atomizing component 3. After the heating element is powered on, heat is generated. E-liquid enters the oil-guiding cotton through the oil storage tank 6 and is heated into a gaseous state on the heating element. The current heats and atomizes the e-liquid absorbed by the oil-guiding cotton. When outside air flows through the heating element, it carries away the atomized smoke and flows out from the suction port 11. When inhalation stops, the air pressure inside the lower shell 5 stabilizes, the microphone stops working, the circuit board notifies the power supply 51 to stop supplying power to the atomizing component 3, and the heating element stops heating.
