Description

Technical Field

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

[0002] Electronic cigarettes generally consist of a casing, inside which is a reservoir containing e-liquid. A mouthpiece is located at the top of the reservoir, and a battery and circuit board are located at the bottom. An air duct is also installed inside the reservoir, with one end connected to the mouthpiece and the other end connected to an air inlet that allows access to outside air. An e-liquid inlet is also located within the air duct, connecting to the reservoir. An atomizing component is installed inside the air duct, 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 atomizing component.

[0003] For ease of use, e-cigarettes are pre-filled with e-liquid in the reservoir after production. Since the e-liquid enters the atomizing component through the inlet, and the atomizing component is exposed to air, the aroma of the e-liquid evaporates into the air. Long-term storage will lead to a decrease in the quality of the e-liquid. Furthermore, if the atomizing component is constantly immersed in e-liquid, too much e-liquid will accumulate and enter the airflow tube, causing the e-liquid to flow out along the airflow tube. This is especially true when air pressure changes, which will increase the likelihood of e-liquid leakage. Additionally, during transportation, the e-cigarette may be vibrated, causing e-liquid to enter the airflow tube through the atomizing component, resulting in e-liquid flowing out along the airflow tube. Utility Model Content

[0004] The main objective of this application is to provide a liquid storage device to solve the technical problem of how to maintain the quality of e-liquid over a long period of time.

[0005] To achieve the above objectives, this application proposes a liquid storage device, comprising:

[0006] A first oil tank is provided with a first channel, which connects the first oil tank to the outside. The first oil tank is used to hold e-liquid.

[0007] A sealing element includes a first sealing body and a second sealing body. The first sealing body has a first flow channel and is installed in the first channel. The second sealing body abuts against the inner wall of the first channel. One end of the first flow channel is connected to a first oil tank, and the other end of the first flow channel ends at the junction of the second sealing body and the first channel.

[0008] The first channel is located at the lower part of the first oil tank. A first flange is provided on the inner wall of the first channel. The first sealing body is located at the upper part of the second sealing body. A first annular groove is recessed on the outer side of the first sealing body. The first flange is engaged with the first annular groove.

[0009] The first flow channel is formed by opening downward from the upper surface of the first sealing body. The bottom wall of the first flow channel is lower than the bottom wall of the first annular groove. The distance from the inner wall of the first flow channel to the center of the first sealing body is L1, and the distance from the inner wall of the first annular groove to the center of the first sealing body is L2, where L1 < L2.

[0010] The first flow channel extends outward and penetrates the side of the first sealing body.

[0011] A first blind hole is formed on the upper surface of the first sealing body, and the bottom wall of the first blind hole is higher than the bottom wall of the first annular groove.

[0012] The second sealing body extends downward from the bottom of the first sealing body. The bottom wall of the first flow channel extends downward and outward to form a first guide groove. The lower surface of the second sealing body is opened upward to form a second clearance groove. The lower end of the first guide groove is lower than the top surface of the second clearance groove.

[0013] The second sealing body has multiple protruding ribs on its side, which abut against the inner wall of the first channel and are located below the first guide groove.

[0014] This design also provides an atomizing device, which includes the aforementioned liquid storage device, and further includes: a second oil tank for mounting on the lower part of the first oil tank, the second oil tank having a second channel connecting the second oil tank to the outside, a connecting portion extending inward from the inner wall of the second channel, a pushing member extending upward from the connecting portion, and a second clearance groove formed on the lower surface of the second sealing body, wherein when the pushing member presses against the top wall of the second clearance groove, the second sealing body moves toward the pushing member, and the outer side of the second sealing body moves away from the inner wall of the first channel, facilitating the entry of e-liquid in the first oil tank into the second channel through the first flow channel.

[0015] The second channel is located at the top of the second oil tank. A sealing ring is also provided on the outside of the first channel. After the first channel is inserted into the second channel, the inner wall of the second channel abuts against the sealing ring.

[0016] The second oil tank is also equipped with a pipe with an oil inlet. The oil inlet is connected to the second oil tank, and an atomizing component is installed inside the pipe corresponding to the oil inlet.

[0017] The sealing element described in this application includes a first sealing body and a second sealing body.

One end of the first flow channel connects to the first oil tank, and the other end of the first flow channel terminates at the junction of the second sealing body and the first channel. The sealing element can store e-liquid in a liquid storage device, preventing the e-liquid from contacting the outside air, preventing the e-liquid from deteriorating, and effectively ensuring the quality of the e-liquid. When needed, when the pusher pushes the top wall of the second clearance groove, the second sealing body moves towards the pusher, and the outer side of the second sealing body moves away from the inner wall of the first channel, facilitating the entry of e-liquid in the first oil tank into the second channel through the first flow channel, and facilitating the atomization component in the second oil tank to atomize it.

[0033] the following Figure 1-8This section will primarily describe the specific structure of the liquid storage device. Please refer to the figure below. A liquid storage device 1 includes: a first oil tank 14, which has a first channel 11 connecting it to the outside. The first oil tank 14 is used to store e-liquid; a sealing element 3, which includes a first sealing body 31 and a second sealing body 32. The first sealing body 31 has a first flow channel 312 and is installed in the first channel 11. The second sealing body 32 abuts against the inner wall of the first channel 11. One end of the first flow channel 312 connects to the first oil tank 14, and the other end terminates at the intersection of the second sealing body 32 and the first channel 11. There can be one or two first oil tanks 14; this design uses two, but for ease of explanation, one will be used. The first oil tank 14 can be made of plastic or metal, such as stainless steel. The sealing element 3 can be made of silicone or rubber. The sealing element 3 has certain deformation characteristics or elasticity after being subjected to force. A mouthpiece is provided at the top of the first oil tank 14 to facilitate inhalation of smoke through the mouth.

[0034] The first channel 11 is located at the lower part of the first oil tank 14. The first channel 11 is made of plastic material and protrudes from the lower surface of the first oil tank 14. A first flange 12 is provided inward on the inner wall of the first channel 11. The first flange 12 is located at the upper part of the first channel 11 and is circular, surrounding the inner wall of the first channel 11. The first sealing body 31 is located above the second sealing body 32. The first sealing body 31 and the second sealing body 32 are integrally formed. A first annular groove 311 is recessed on the outer side of the first sealing body 31 and surrounds the outer side of the first sealing body 31. The first flange 12 is snapped into the first annular groove 311. During assembly, since the diameter of the first channel 11 is larger than the diameter of the first flange 12, the first sealing body 31 can be inserted into the first annular groove 311 from bottom to top, which is convenient for installation.

[0035] The first flow channel 312 is formed downward from the upper surface of the first sealing body 31. The bottom wall of the first flow channel 312 is lower than the bottom wall of the first annular groove 311. The distance between the inner wall of the first flow channel 312 and the center of the first sealing body 31 is L1, and the distance between the inner wall of the first annular groove 311 and the center of the first sealing body 31 is L2. L1 < L2, so that there is a gap between the inner wall of the first flow channel 312 and the first flange 12. In use, the e-liquid flows downward through the first flow channel 312, preventing it from being blocked by the first flange 12.

[0036] The first flow channel 312 extends outward and penetrates the side of the first sealing body 31, which facilitates the forming of the first flow channel 312 and increases the contact area between the upper part of the first flow channel 312 and the e-liquid, making it easier for the e-liquid to enter the upper part of the first flow channel 312 and then flow downward. If the first flow channel 312 does not extend outward and penetrate the side of the first sealing body 31, it can still be used normally, but this design is inconvenient to manufacture.

[0037] A first blind hole 314 is formed downwards on the upper surface of the first sealing body 31, and the bottom wall of the first blind hole 314 is higher than the bottom wall of the first annular groove 311. This advantage is reflected in the assembly process. Specifically, as the first sealing body 31 is inserted into the first annular groove 311 from bottom to top, due to its own elasticity, the first blind hole 314 can provide a clearance space, which facilitates the inward contraction of the side of the first sealing body 31 and the passage of the head of the first sealing body 31 through the space formed by the first flange 12. After the head of the first sealing body 31 has passed the first flange 12, the first sealing body 31 is pushed further, and the first flange 12 is engaged with the first annular groove 311. Due to its own elasticity, the side of the first sealing body 31 expands outward again, preventing the first sealing body 31 from falling out of the space formed by the first flange 12. For ease of installation, a guide slope (unlabeled) can also be provided on the outer edge of the upper surface of the first sealing body 31.

[0038] The second sealing body 32 extends downward from the bottom of the first sealing body 31. A first guide groove 313 extends downward and outward from the bottom wall of the first flow channel 312. A second clearance groove 321 is formed upward on the lower surface of the second sealing body 32. The lower end of the first guide groove 313 is lower than the top surface of the second clearance groove 321. When the outer side of the second sealing body 32 is subjected to extrusion pressure, the design of the second clearance groove 321 facilitates the inward movement of the second sealing body 32. At this time, the distance between the first guide groove 313 and the inner wall of the first channel 11 is increased, which facilitates the downward flow of e-liquid in the first flow channel 312. Then, it flows outward and downward into the first guide groove 313, and then flows downward through the gap between the first guide groove 313 and the inner wall of the first channel 11 to reach the bottom of the first channel 11.

[0039] The second sealing body 32 has multiple protruding ribs 322 on its side. The protruding ribs 322 abut against the inner wall of the first channel 11. The protruding ribs 322 are located below the first guide groove 313. The protruding ribs 322 are annular and integrally formed with the second sealing body 32. The protruding ribs 322 can increase the airtightness between the second sealing body 32 and the inner wall of the first channel 11. When not in use, they can prevent e-liquid from flowing out through the gap between the second sealing body 32 and the inner wall of the first channel 11. The protruding ribs 322 can also increase the stability between the second sealing body 32 and the first channel 11 and prevent relative sliding between the two sealing bodies and the first channel 11.

[0040] The liquid storage device 1 provided in this design allows e-liquid to be stored, preventing it from contacting outside air and thus preventing deterioration and ensuring its quality. The storage device 1 can also be transported independently, effectively preventing leakage due to vibration or changes in atmospheric pressure. E-liquid can be injected into the storage device 1 from the top, and then sealed directly at the top using silicone sealant; alternatively, it can be injected from the bottom, with the first channel 11 initially without a seal 3, through which the e-liquid enters, and then the seal 3 is installed. This facilitates subsequent transportation, storage, and use.

[0041] This design also provides an atomizing device, including the aforementioned liquid storage device 1, and further including: a second oil tank 2 for mounting on the lower part of the first oil tank 14, the second oil tank 2 having a second channel 21, the second channel 21 connecting the second oil tank 2 to the outside, the inner wall of the second channel 21 extending inward to a connecting part 22, the connecting part 22 extending upward to a pushing member 23, there being a gap between two adjacent connecting parts 22, the pushing member 23 being provided at the intersection of multiple connecting parts 22, the pushing member 23 being columnar, the lower surface of the second sealing body 32 having a second clearance groove 321 opening upward, wherein, when the pushing member 23 presses against the top wall of the second clearance groove 321, the second sealing body 32 moves toward the pushing member 23, the outer side of the second sealing body 32 being away from the inner wall of the first channel 11, facilitating the entry of e-liquid in the first oil tank 14 into the second channel 21 through the first flow channel 312. The second oil tank 2 can be made of plastic or metal, such as stainless steel. The second oil tank 2 is used to temporarily store e-liquid to facilitate subsequent atomization.

[0042] The second channel 21 is located at the top of the second oil tank 2. A sealing ring 13 is also provided on the outside of the first channel 11. After the first channel 11 is inserted into the second channel 21, the inner wall of the second channel 21 abuts against the sealing ring 13. Specifically, when the first oil tank 14 and the second oil tank 2 approach and mate, the first channel 11 is inserted into the second channel 21, and the sealing ring 13 begins to contact the inner wall of the second channel 21. The pusher 23 pushes upward against the top wall of the second clearance groove 321. Since the elastic first sealing body 31 is fixed by the first flange 12, the first sealing body 31 will continue to move upward, and the second sealing body 32 will also be pulled. The second sealing body 32 moves closer to the pusher 23, and the outer rib 322 of the second sealing body 32 separates from the inner wall of the first channel 11, creating a gap. The e-liquid in the first oil tank 14 flows out sequentially through the first flow channel 312, the first guide groove 313, the gap between the outer rib 322 of the second sealing body 32 and the inner wall of the first channel 11, and then enters the bottom of the second channel 21, and then enters the second oil tank 2 through the gap between the connecting parts 22. The flow path of the e-liquid can be found in [reference needed]. Figure 8 The direction indicated by the middle arrow.

[0043] The second oil tank 2 is also equipped with a tube 5, which can be a steel pipe or a high-temperature resistant plastic pipe. The tube 5 has an oil inlet hole that connects to the second oil tank 2. An atomizing component 4 is installed inside the tube 5 corresponding to the oil inlet hole. The atomizing component 4 is connected to a control board, which in turn is connected to a battery. The control board controls the battery output to control the operating mode of the atomizing component 4. A bracket 24 is also installed at the lower part of the second oil tank 2. The bracket 24 has an air inlet hole. Outside air flows into the lower part of the tube 5 through the air inlet hole, passes through the atomizing component 4, and carries the atomized smoke upwards before flowing out through the mouthpiece. The e-liquid in the second oil tank 2 flows into the atomizing component 4 through the oil inlet hole, where it is heated into gaseous smoke. Air flowing through the atomizing component 4 carries away the gaseous smoke. In order to ensure that e-liquid continuously flows from the first oil tank 14 into the second oil tank 2, a positioning device, such as a matching of a protrusion and a buckle, can be set between the first oil tank 14 and the second oil tank 2 to prevent the first oil tank 14 and the second oil tank 2 from separating.
