Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an oil supply bottle. Background Technology

[0002] Atomizing devices consist of an atomizing component and a power supply component. The power supply component provides power to the atomizing component, heating it and converting the adsorbed oil into an aerosol for the user to inhale. To meet the requirements for a large number of puffs, a separate refill bottle is usually provided. The refill bottle is used to fill the atomizing component with oil. During transportation, the refill bottle is packaged separately. When using the device, the user opens the refill bottle and installs it on the atomizing component to supply oil.

[0003] In existing technologies, due to the unreasonable structural design of the fuel supply bottle, users either need additional tools to open it, making operation inconvenient, or the opening method is too simple, making it easy for children to learn and potentially leading to accidental opening and leakage. Therefore, a new type of fuel supply bottle needs to be designed that allows users to open it without auxiliary tools while also having a child lock function to prevent accidental operation by children. Utility Model Content

[0004] The main purpose of this utility model is to provide a fuel bottle that solves the problem that existing fuel bottles either require additional tools to open or have an overly simple opening method that is easy for children to master and may lead to misoperation.

[0020] The technical solution of this utility model requires the user to press down on the cover and rotate it until the limiting protrusion aligns with the disassembly notch. Only then can the user release the cover to detach the sealing sleeve and sealing plug from the neck of the bottle and open the oil supply port. Because the operation involves several steps, it is not easy for children to master, thus effectively preventing children from accidentally opening the oil supply bottle and causing oil leakage, achieving a child lock function.

[0040] The following will mainly describe the specific structure of the fuel supply bottle.

[0041] Reference Figures 1 to 8 In this embodiment of the utility model, the oil supply bottle includes:

[0042] The bottle body 100 has an oil supply chamber 110 inside and a bottleneck 120 at the top. The bottleneck 120 is provided with an oil supply port 121 that communicates with the oil supply chamber 110. The outer peripheral wall of the bottleneck 120 is provided with a limiting protrusion ring 122 that extends circumferentially therein. The limiting protrusion ring 122 is provided with a disassembly and assembly notch 123 that penetrates its upper and lower sides.

[0043] A sealing plug 200 is detachably inserted into the oil supply port 121 to seal the oil supply port 121, and the outer wall of the sealing plug 200 is provided with a limiting structure.

[0044] A sealing sleeve 300 is fitted onto the bottleneck 120 and can rotate circumferentially along the bottleneck 120. The inner wall of the sealing sleeve 300 is provided with a limiting protrusion 310 and a mating structure. The limiting protrusion 310 can pass through the disassembly notch 123. The mating structure cooperates with the limiting structure to make the sealing sleeve 300 axially limited to the sealing plug 200. The outer wall of the sealing sleeve 300 is provided with a push-resistant structure.

[0045] A cover 400 is provided on the sealing sleeve 300 and can rotate around the circumference of the sealing sleeve 300. The inner wall of the cover 400 is provided with a downwardly extending abutment post 440 and a main push structure for pushing the pushed structure, so that the cover 400 can drive the sealing sleeve 300 to rotate.

[0046] The cover 400 has an inner peripheral wall and the sealing sleeve 300 have an outer peripheral wall, one of which has a limiting groove 410 and the other has a limiting protrusion 320. The limiting protrusion 320 can move up and down along the width of the limiting groove 410, so that the cover 400 has an installation position and a detachable position. In the installation position, the abutment post 440 is close to or in contact with the sealing plug 200, the main pushing structure is located above the pushed structure, and the limiting protrusion 310 is located below the limiting protrusion ring 122 to hold the cover 400 and the sealing sleeve 300 together. 0 and sealing plug 200 are limited to the bottleneck 120; in the detachable position, the abutment post 440 presses against the sealing plug 200, the sealing plug 200 is in a compressed state, the main push structure is located to the side of the pushed structure so as to push the pushed structure until the limiting protrusion 310 is directly opposite the disassembly notch 123, so that after the cover 400 is moved upward, the limiting protrusion 310 passes through the disassembly notch 123, and the cover 400 moves the sealing sleeve 300 and sealing plug 200 away from the bottleneck 120 to open the oil supply port 121.

[0047] Specifically, in this embodiment, since the limiting protrusion 320 can move up and down along the width direction of the limiting groove 410, the user can move the cover 400 up and down. When the oil bottle leaves the factory, the cover 400 is in the installation position. At this time, the main push structure is located above the push structure. Even if the cover 400 is rotated, the sealing sleeve 300 will not rotate, so that the limiting protrusion 310 of the sealing sleeve 300 remains below the limiting protrusion ring 122. Thus, the sealing sleeve 300 cannot be dislodged upward from the bottleneck 120, so that the sealing sleeve 300 is limited to the bottleneck 120. Thus, the sealing plug 200 and the cover 400 also cannot be dislodged upward from the bottleneck 120. That is, at this time, the cover 400, the sealing sleeve 300 and the sealing plug 200 are limited to the bottleneck 120 to ensure the sealing of the oil bottle. Moreover, since the abutment post 440 is close to or in contact with the sealing plug 200 at this time, it can limit the cover body and prevent the cover body 400 from sliding down, thereby ensuring the stability of the cover body 400.

[0048] When the fuel bottle needs to be installed on the atomizing assembly, press down on the cap 400 until the main push structure is located to the side of the pushed structure, and then rotate the cap 400. At this time, the main push structure of the cap 400 can push the pushed structure of the sealing sleeve 300 to rotate. When the sealing sleeve 300 rotates to the point where the limiting protrusion 310 is aligned with the insertion notch, release the movable cap 400. At this time, the sealing plug 200 resets, thereby causing the sealing sleeve 300 and the cap 400 to move upward automatically. The limiting protrusion 310 passes through the disassembly notch 123, thereby releasing the limiting protrusion ring 122 from limiting the sealing sleeve 300, so that the sealing sleeve 300 can be disengaged upward from the bottle. Neck 120, due to the axial limiting function of limiting groove 410 and limiting protrusion 320, when sealing sleeve 300 is separated from neck 120, it will also drive cap 400 to be separated together. Due to the cooperation between the limiting structure of sealing plug 200 and the matching structure of sealing sleeve 300, sealing sleeve 300 is axially limited to sealing plug 200. When sealing sleeve 300 moves upward and separates from neck 120, it will also pull sealing plug 200 to move upward and separate from neck 120. In this way, by removing sealing plug 200, the oil supply port 121 of bottle 100 can be exposed, so that after being assembled with atomizing component, oil can be supplied to atomizing component.

[0049] The technical solution of this utility model requires the user to press down on the cover 400 and rotate it until the limiting protrusion 310 is aligned with the disassembly notch 123. Only then can the user release the cover 400 to detach the sealing sleeve 300 and sealing plug 200 from the neck 120 and open the oil supply port 121. Because the operation involves multiple steps, it is not easy for children to master, thus effectively preventing children from accidentally opening the oil bottle and causing oil leakage, achieving a child lock function. Since this process does not require auxiliary tools, it is convenient to operate and improves the user experience.

[0050] Regarding the specific forms of the pushing and pushed structures, in some embodiments, the outer top wall of the sealing sleeve 300 is provided with a pushed block 330, which constitutes the pushed structure. The inner top wall of the cover 400 is provided with a downwardly protruding pushing strip 420, which constitutes the pushing structure. One side of the pushing strip 420 is connected to the inner sidewall of the cover 400. Because the pushing strip 420 is connected to the inner sidewall of the cover 400, the strength of the pushing strip 420 is increased, making it less prone to deformation, thereby ensuring that it can push the pushed block 330 to rotate, thus ensuring that the cover 400 can drive the sealing sleeve 300 to rotate.

[0051] To ensure that the cover 400 rotates along a preset trajectory, in some embodiments, a limiting ring 340 protrudes from the outer top wall of the sealing sleeve 300, and a plurality of limiting protrusions 430 protrude downward from the inner top wall of the cover 400, arranged circumferentially along the cover 400. The plurality of limiting protrusions 430 extend into the limiting ring 340 and are adjacent to the inner wall of the limiting ring 340. Thus, the limiting ring 340 limits the limiting protrusions 430, ensuring that the cover 400 rotates along the preset trajectory without deviation, thereby ensuring that the cover 400, sealing sleeve 300, and sealing plug 200 can be easily removed to open the oil supply port 121.

[0052] Regarding the specific form of the axial limiting of the sealing sleeve 300 to the sealing plug 200, in some embodiments, the sealing plug 200 includes a limiting part 210 and a sealing part 220 from top to bottom. The outer diameter of the limiting part 210 is smaller than the outer diameter of the sealing part 220. The sealing part 220 is inserted into the oil supply port 121. A limiting boss 211 protrudes from the side wall of the limiting part 210. The lower wall of the limiting boss 211 is flush with the side wall of the limiting part 210. A limiting groove 212 is formed between the top walls of the sealing part 220, which constitutes the limiting structure. An extension ring 350 protrudes downward from the inner top wall of the sealing sleeve 300. An extension protrusion 351 protrudes from the side of the extension ring 350 facing the sealing plug 200. The limiting part 210 extends into the extension ring 350, and the extension protrusion 351 constitutes the mating structure. The extension protrusion 351 extends into the limiting groove 212. That is, when the cover 400 is rotated to a detachable position and then the cover 400 is released, causing the sealing sleeve 300 to move upward, the extension protrusion 351 of the sealing sleeve 300 applies an upward force to the groove wall of the limiting groove 212, causing the sealing plug 200 to move upward as well, thereby removing the sealing plug 200 from the oil supply port 121.

[0053] Furthermore, the outer wall of the sealing part 220 is provided with a plurality of sealing protrusions 221 extending circumferentially thereon. The plurality of sealing protrusions 221 are arranged circumferentially along the sealing part 220, and the sealing protrusions 221 abut against the inner wall of the oil supply port 121, thereby improving the sealing effect of the sealing part 220.

[0054] In some embodiments, a limiting step is formed on the inner wall of the bottleneck 120, and a mating step 230 is formed on the outer wall of the sealing plug 200, the step surface of the mating step 230 fitting with the step surface of the limiting step. This prevents the sealing plug 200 from being forced into the oil supply chamber 110, thereby ensuring that the sealing plug 200 is stably positioned in a preset location and performs its sealing function.

[0055] In some embodiments, the disassembly notch 123 includes, from bottom to top, an entry guide section 124, a connecting section 125, and a guide-away section 126. One side wall of the entry guide section 124 includes a guide ramp, so that the width of the entry guide section 124 gradually decreases from bottom to top. The guide ramp is used to guide the limiting protrusion 310 into the disassembly notch 123. The width of the guide-away section 126 gradually increases from bottom to top. The guide ramp guides the limiting protrusion 310 into the disassembly notch 123, and the gradual increase in the width of the guide section from bottom to top allows the limiting protrusion 310 to smoothly and quickly leave the disassembly notch 123, thereby improving the smoothness of disassembling the sealing sleeve 300 and smoothly opening the oil inlet.

[0056] In some embodiments, the outer wall of the bottleneck 120 is provided with a stop 127. The side wall surface of the stop 127 facing the limiting protrusion 310 is in contact with and located on the same plane as the inner wall surface of the lower end of the disassembly notch 123. When rotating the cover 400, if the user feels that it cannot be rotated any further, it indicates that the cover 400 has been rotated to the detachable position. That is, the stop 127 makes it easy for the user to sense whether the cover 400 has been rotated to the correct position, thereby facilitating the user to quickly open the oil filler port and improving the user's operating experience.

[0057] In some embodiments, the outer peripheral wall of the cover 400 is provided with a plurality of anti-slip recesses 450, which extend along the axial direction of the cover 400 and are arranged circumferentially along the cover 400. This makes it less likely for the user's hand to slip when rotating the cover 400, facilitating user operation.

[0058] In some embodiments, the outer peripheral wall of the bottleneck 120 is provided with a mounting groove 128 extending circumferentially therefrom. The mounting groove 128 is located below the limiting protrusion ring 122. The oil supply bottle also includes a sealing ring 500, which is installed in the mounting groove 128 and abuts against the inner wall of the oil inlet channel of the atomizing component. The mounting groove 128 has a limiting function for the sealing ring 500, ensuring that the sealing ring 500 can stably and reliably perform its sealing function.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
