Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a liquid storage device and an atomizer using the liquid storage device. Background Technology

[0002] Electronic cigarettes generally consist of an e-liquid reservoir containing e-liquid, a mouthpiece at the top, and a battery and circuit board at the bottom. A steel tube is also installed inside the reservoir; one end connects to the mouthpiece, and the other end connects to an air inlet, which allows air to enter. An e-liquid inlet is located within the steel tube and connects to the reservoir. The e-liquid assembly is connected to the circuit board, which in turn connects to the battery. The circuit board controls the battery's output power, which in turn controls the heating power of the e-liquid assembly. E-liquid from the reservoir enters the e-liquid assembly through the inlet. The battery provides power to the heating element of the e-liquid assembly, allowing the e-liquid to continuously flow into the wicking material. When the heating element is powered, it heats the liquid e-liquid into a vapor, thus atomizing it.

[0003] In this type of e-cigarette, the e-liquid is in contact with the wicking cotton for a long time, and the wicking cotton becomes saturated with e-liquid. Over time, this will reduce the wicking cotton's adsorption capacity. In addition, the wicking cotton is exposed in the steel tube, and the e-liquid can easily evaporate into the air, resulting in a decrease in the concentration of the e-liquid, which does not meet the expected quality requirements and results in a poor taste after vaporization.

[0004] To solve the above problems, a silicone sleeve is installed on the outside of the steel pipe. The upper part of the silicone sleeve is connected to a pull rod, which is inserted into the steel pipe. The upper end of the pull rod extends from the mouthpiece and seals the oil inlet of the oil storage tank through the silicone sleeve to isolate the e-liquid from the atomizing component. A pre-cut wire is set between the pull rod and the silicone sleeve. When in use, pulling the pull rod forcefully moves the silicone sleeve, causing it to detach from the oil inlet. Continuing to pull the pull rod separates it from the silicone sleeve at the pre-cut wire, and the e-liquid in the oil storage tank enters the atomizing component through the oil inlet. However, this design is complex and inconvenient to operate. First, a silicone sleeve and a pull rod must be designed, and the bonding force between the silicone sleeve and the pull rod must be controlled. It is also necessary to control the friction between the silicone sleeve and the steel pipe. Otherwise, it is easy for the pull rod to be pulled out during the process, but the silicone sleeve is still sealing the oil inlet, preventing the e-liquid in the oil storage tank from entering the atomizing component.

[0005] Therefore, it is necessary to design a liquid storage device to overcome the above-mentioned defects. Utility Model Content

[0006] The main objective of this application is to provide a liquid storage device that solves the technical problems of complex structure, inconvenient operation, and poor quality of e-liquid after long-term storage.

After the protrusion is inserted into the channel through the oil passage hole, the cover moves upward and separates from the retaining parts. The oil supply chamber is connected to the upper part of the oil passage through the through groove.

[0020] The buffer chamber is also equipped with a tube, which has an oil inlet. The oil inlet is connected to the buffer chamber, and an atomizing component is installed inside the tube corresponding to the oil inlet.

[0039] the following Figure 1-10 This section will primarily describe the specific structure of the liquid storage device. Please refer to the figure below. A liquid storage device 1 includes: an oil supply chamber 18, which has an oil passage 11 connecting it to the outside. The oil supply chamber 18 is used to hold e-liquid. The oil passage 11 is located at the lower part of the oil supply chamber 18, with its bottom protruding from the lower part of the oil supply chamber 18. The upper surface of the oil passage 11 protrudes from the upper surface of the bottom wall of the oil supply chamber 18. The upper part of the oil supply chamber 18 is sealed with a silicone cap. There are two oil supply chambers 18, each semi-cylindrical, located on the outside of a tube body 5. The two oil supply chambers 18 form a cylinder, with the tube body 5 located in the middle of the two oil supply chambers 18. The oil supply chambers 18 can be made of plastic or metal. A mouthpiece is provided at the upper part of the oil supply chamber 18 for inhalation through the mouth.

[0040] A cover 3 is installed at one end of the oil passage 11 and located outside the oil passage 11 to seal the oil supply chamber 18. The cover 3 is made of silicone or plastic material and is located inside the oil supply chamber 18. An elastic body 4 is installed in the oil passage 11. One end of the elastic body 4 abuts against the cover 3, and the other end of the elastic body 4 abuts against the other end of the oil passage 11. The elastic body 4 has a channel 44 that passes through one end and the other end of the elastic body 4. The elastic body 4 is made of silicone or rubber material. The elastic body 4 deforms under force. The elastic body 4 can be compressed in the vertical direction and can expand in the horizontal direction.

[0041] The inner wall of the upper end of the oil passage 11 extends inward with multiple retaining parts 12, and there is a through groove 13 between two adjacent retaining parts 12. The through groove 13 connects the oil supply chamber 18 and the oil passage 11. Specifically, the retaining part 12 extends towards the center of the oil channel 11 and intersects at the center of the oil channel 11 to form a connecting part 14. The channel 44 penetrates the upper and lower ends of the elastic body 4. The cross-sectional area of ​​the connecting part 14 is L1, and the cross-sectional area of ​​the channel 44 at the upper end of the elastic body 4 is L2, where L1 < L2, to facilitate the entry of e-liquid into the channel 44 through the through groove 13. In this design, the connecting part 14 is circular or square. The connecting part 14 is located directly above the elastic body 4. The retaining part 12 connects the connecting part 14 and the inner wall of the oil channel 11. The outer sides of the two retaining parts 12, the outer side of the connecting part 14, and the inner wall of the oil channel 11 together constitute the through groove 13. The e-liquid in the oil tank 18 flows downward through the through groove 13 and then enters the channel 44 of the elastic body 4.

[0042] The cover 3 includes a head 31 and a protrusion 32. The protrusion 32 extends downward from the head 31, and there is a gap between two adjacent protrusions 32 to facilitate the entry of the retaining part 12. The protrusion 32 is engaged with the through groove 13, and the head 31 abuts against and seals the end of the oil passage 11. The protrusion 32 and the through groove 13 are matched. After the protrusion 32 is pushed upward, it can disengage from the through groove 13, squeezing the head 31. The protrusion 32 can then enter the through groove 13. As the depth of entry continues to advance, the top surface of the head 31 finally abuts against the oil passage 11, completing the seal between the cover 3 and the oil passage 11.

[0043] The elastomer 4 includes an upper connector 41, a lower connector 42, and a curved portion 43. The upper end of the curved portion 43 is connected to the lower part of the upper connector 41, and the lower end of the curved portion 43 is connected to the upper part of the lower connector 42. The outer side of the curved portion 43 is used to abut against the inner wall of the oil passage 11, and the upper connector 41 is used to abut against the lower surface of the retaining portion 12. The bent portion 43 includes at least one structural unit, which may have two, three, or more. The structural unit includes a first segment 431 and a second segment 432. The first segment 431 extends outward from the lower part of the upper connector 41, and the second segment 432 extends inward from the free end of the first segment. The free end of the second segment 432 is connected to the upper part of the lower connector 42. When the structural unit is fully stretched in the vertical direction, the diameter of the channel 44 is equal at any position of the elastic body 4. Since the elastic body 4 is compressible, after the elastic body 4 is squeezed in the vertical direction, the diameter of the channel 44 is unevenly distributed along the axial direction of the elastic body 4.

[0044] The inner wall of the lower end of the oil passage 11 extends inward to form a supporting surface 15. The lower surface of the lower connector 42 abuts against the upper surface of the supporting surface 15. An oil passage hole 16 is provided through the center of the supporting surface 15, and the oil passage hole 16 is located below the oil passage 11. The oil passage hole 16 is smaller than the cross-section of the lower connector 42, which prevents the lower connector 42 from detaching from the oil passage hole 16 after the elastomer 4 is inserted into the oil passage 11.

[0045] An atomizer includes the aforementioned liquid storage device 1, and further includes: a buffer chamber 2, the upper part of which is provided with a connecting groove 21, the connecting groove 21 being circular, a protruding post 22 extending upward from the bottom wall of the connecting groove 21, the protruding post 22 being located at the center of the connecting groove 21, the protruding post 22 being cylindrical, a flow channel 23 being formed downward on the upper surface of the protruding post 22, the flow channel 23 extending downward and connecting to the buffer chamber 2, a horizontal groove 24 being formed downward on the upper surface of the protruding post 22, the horizontal groove 24 connecting to the flow channel 23, the horizontal groove 24 penetrating the side of the protruding post 22, facilitating the entry of e-liquid into the horizontal groove 24, and then into... The flow channel 23 is used to guide the elastomer 4 upward by inserting the protrusion 22 into the channel 44. The elastomer 4 moves upward and pushes the cover 3 upward. The oil supply chamber 18 is connected to the flow channel 23 through the channel 44. The buffer chamber 2 is also equipped with a tube 5 with an oil inlet hole connected to the buffer chamber 2. The tube 5 is equipped with an atomizing component 6 corresponding to the oil inlet hole. A sealing ring 17 is also provided on the lower outer side of the oil channel 11. When the oil channel 11 and the docking groove 21 are assembled, the sealing ring 17 can increase the airtightness between the outer side of the oil channel 11 and the side wall of the docking groove 21 to prevent e-liquid leakage.

[0046] The atomizing component 6 is also connected to a control board via a lead wire. The control board is connected to a battery, and the control board controls the output of the battery to control the working mode of the atomizing component 6. The lower part of the buffer chamber 2 is also equipped with a bracket with an air inlet. Outside air flows into the lower part of the tube body 5 through the air inlet, and through the atomizing component 6, the atomized smoke is carried upward and then flows out through the mouthpiece.

[0047] After the protrusion 22 is inserted into the channel 44 through the oil passage 16, the elastic body 4 is subjected to an upward force. The lower connector 42 pushes the bent part 43 upward, the bent part 43 pushes the upper connector 41 upward, and the upper connector 41 pushes the protrusion 32 upward. The protrusion 32 slowly separates from the retaining part 12, and the cover 3 moves upward. At this time, e-liquid can flow in through the gap between two adjacent protrusions 32. Since the through groove 13 is still sealed at this time, the e-liquid cannot enter the oil passage 11. Continue to push the buffer chamber 2. The upward movement of the protrusion 22 pushes the elastic body 4 upward, and the protrusion 32 completely separates from the retaining part 12. The e-liquid can flow into the oil channel 11 through the channel 13, enter the channel 44 along the oil channel 11, flow downward along the channel 44, enter the guide channel 23, continue to flow downward into the buffer chamber 2, and then enter the atomizing component 6 in the tube body 5 through the oil inlet hole. It is heated into a gaseous state on the atomizing component 6. This design has a simple structure and is easy to operate. When using it, you only need to push the buffer chamber 2 upward or squeeze the oil supply chamber downward to realize the conduction of e-liquid.
