DETAILED DESCRIPTION
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0040] To solve the above technical problems, please refer to Figures 1 to 6 The embodiment of the present application provides a liquid storage structure 10, and the liquid storage structure 10 includes:
[0041] A liquid storage element 100, wherein a liquid storage cavity 120 is formed inside the liquid storage element 100, and a liquid injection hole 110 is provided on the liquid storage element 100, and the liquid injection hole 110 communicates with the liquid storage cavity 120 and the external environment;
[0042] The sealing member 200 is connected to the liquid storage member 100 and can reciprocate toward the direction of the liquid injection hole 110 to control the liquid injection hole 110 to be connected or blocked;
[0043] Among them, one of the liquid storage component 100 and the sealing component 200 is provided with a limiting groove 130, and the other is provided with a limiting protrusion 210. The limiting protrusion 210 is located in the limiting groove 130, and the limiting groove 130 is used to limit the relative movement distance of the limiting protrusion 210.
[0044] In this embodiment, the movement direction of the sealing member 200 isFigure 2 in the X direction (left - right direction) in Figure 5 and Figure 6 As can be seen from
[0045] When the seal 200 approaches the liquid injection hole 110 in the X direction, the seal 200 will block the liquid injection hole 110. When the seal 200 moves away from the liquid injection hole 110 in the X direction, the seal 200 will be misaligned with the liquid injection hole 110, thereby exposing the liquid injection hole 110, so that the user can add the atomizing liquid into the liquid storage cavity 120 through the liquid injection hole 110.
[0046] Furthermore, please refer to Figure 4 and Figure 6 During the movement of the seal 200, since the liquid storage member 100 is provided with a limiting groove 130 and the limiting protrusion 210 is located in the limiting groove 130, when the seal 200 moves in the X direction to a certain extent, the limiting protrusion 210 will abut against the inner wall of the limiting groove 130. At this time, the seal 200 cannot move further. That is, the cooperation of the limiting groove 130 and the limiting protrusion 210 realizes the limitation of the movement degree of the seal 200 relative to the liquid storage member 100, thereby avoiding the detachment of the seal 200. It can be understood that the sealing protrusion 220 can also be provided on the liquid storage member 100, and the limiting groove 130 is provided on the seal 200.
[0047] In the direction perpendicular to the length direction, the limiting groove 130 is provided with two opposite guiding side walls 131. The guiding side walls 131 and the bottom wall of the limiting groove 130 form an obtuse angle, and the shape of the limiting protrusion 210 is adapted to the limiting groove 130.
[0048] In this embodiment, the length direction of the limiting groove 130 is Figure 2 the X direction in
[0049] During the assembly process of the liquid storage structure 10, if the limiting groove 130 and the limiting protrusion 210 are not completely aligned for assembly, it may cause the limiting protrusion 210 to bump against the surface of the liquid storage member 100, thereby causing the limiting protrusion 210 to bend or break. Therefore, the assembly accuracy requirement is high, and thus the assembly efficiency of the liquid storage structure 10 is low. Figure 3 Therefore, in this embodiment, two guiding side walls 131 are provided in the limiting groove 130 and the shape of the limiting protrusion 210 is adapted to the limiting groove 130, that is, in the Figure 2When inserted into the limiting groove 130 in the Z direction, even if there is an offset between the limiting protrusion 210 and the limiting groove 130 and they are not completely aligned, the guiding side wall 131 can still guide the limiting protrusion 210 into the limiting groove 130, thereby effectively improving the assembly efficiency of the liquid storage structure 10.
[0050] Further, please refer to Figure 3 , Figure 5 and Figure 6 , the liquid storage member 100 is provided with a first guiding groove 141 and a second guiding groove 142. The second guiding groove 142 is arranged on the side wall of the first guiding groove 141. The length direction of the first guiding groove 141 is parallel to the moving direction of the sealing member 200. A guiding protrusion 240 is arranged on the side wall of the sealing member 200, and the guiding protrusion 240 is clamped in the second guiding groove 142.
[0051] In this embodiment, the first guiding groove 141 can accommodate the sealing member 200, thereby preventing the sealing member 200 from rotating or shifting. When the sealing member 200 moves to block the liquid injection hole 110, the sealing member 200 can be completely located in the first guiding groove 141. Since the guiding protrusion 240 is clamped in the second guiding groove 142, the sealing member 200 cannot slip off along the Figure 2 Z-axis direction in the middle and separate from the liquid storage member 100, thereby improving the stability of the liquid storage structure 10. At the same time, in this embodiment, the liquid storage member 100 and the sealing member 200 are connected through the second guiding groove 142 and the guiding protrusion 240. This connection method has a simple structure and effectively reduces the production cost of the liquid storage structure 10.
[0052] Further, please refer to Figure 3 , Figure 4 and Figures 6 to 8 , an elastic protrusion 230 is further arranged on the side of the sealing member 200 facing the liquid injection hole 110;
[0053] The elastic protrusion 230 abuts against the bottom of the first guiding groove 141 to make the guiding protrusion 240 in interference fit with the second guiding groove 142.
[0054] In this embodiment, Figure 2 the Z direction in the middle is the up and down direction, and the X direction is the left and right direction. The elastic protrusion 230 can play a role in jacking up the sealing member 200 along the Figure 2 Z direction in the middle, so that the guiding protrusions 240 on both sides of the sealing member 200 abut against the upper wall of the second guiding groove 142. At this time, the elastic protrusion 230 can play a role in increasing the friction force, so that the user receives resistance when pushing and pulling the sealing member 200, avoiding the decrease in hand feeling caused by the too fast movement of the sealing member 200, and at the same time avoiding the collision and damage between the limiting protrusion 210 and the limiting groove 130. It can be understood that the elastic protrusion 230 can be damping silica gel.
[0055] Further, please refer to Figure 2 , Figure 4 and Figure 6 . A sealing protrusion 220 is provided on one side of the seal 200 facing the liquid injection hole 110. The sealing protrusion 220 abuts against the liquid injection hole 110 to seal the liquid injection hole 110.
[0056] In this embodiment, due to the existence of the elastic protrusion 230, there is a certain gap between the seal 200 and the liquid injection hole 110. Even if the seal 200 moves to coincide with the liquid injection hole 110, liquid leakage may occur in the liquid injection hole 110. Therefore, the sealing protrusion 220 is provided in this embodiment. The sealing protrusion 220 can abut against the liquid injection hole 110, thereby eliminating the gap between the liquid injection hole 110 and the seal 200 and playing a role in preventing the atomized liquid from leaking. It can be understood that the sealing protrusion 220 can be pressed against the surface of the liquid injection hole 110 under the action of the elastic protrusion 230 and the second guide groove 142, thereby providing a pre-tightening force to prevent the atomized liquid from leaking.
[0057] Further, please refer to Figures 2 to 4 and Figure 6 . One side of the liquid storage member 100 facing the sealing protrusion 220 is the first surface 30. A convex platform 111 is provided on the first surface 30, and the liquid injection hole 110 is provided on the convex platform 111.
[0058] In this embodiment, if the convex platform 111 is not provided, when the seal 200 moves along the Figure 2 X direction in
[0059] , the sealing protrusion 220 will rub against the first surface 30. Therefore, when the number of movements of the seal 200 reaches a certain level, the sealing protrusion 220 will be worn. At this time, a gap may appear at the connection between the sealing protrusion 220 and the liquid injection hole 110, and then the atomized liquid will flow out from the liquid storage cavity 120.
[0060] Further, please refer to Figures 6 to 8 . The first surface 30 is further provided with an avoidance groove 150. The limiting groove 130 is provided at the bottom of the avoidance groove 150. The avoidance groove 150 is larger than the sealing protrusion 220 to accommodate the sealing protrusion 220.
[0061] In this embodiment, since the elastic protrusion 230 is elastic, firstly, in the process of pressing and pushing the seal 200, the sealing protrusion 220 may move toward the first surface 30, thereby causing the sealing protrusion 220 to still be worn. On the other hand; secondly, the sealing protrusion 220 may also be an elastic part such as silicone, so after releasing the interference fit with the boss 111, it may recover its shape and then contact the first surface 30. At this time, there is still a risk of wear.
[0062] In this embodiment, the avoidance groove 150 is larger than the sealing protrusion 220, which should be understood as the area of the avoidance groove 150 on the XY plane can include the sealing protrusion 220. Therefore, when the sealing protrusion 220 is released from contact with the boss 111, it can enter the avoidance groove 150 instead of contacting the first surface 30. In summary, the avoidance groove 150 of this embodiment can accommodate the sealing protrusion 220, thereby preventing the sealing protrusion 220 from being worn.
[0063] For further information, please refer to Figure 1 , Figure 5 and Figure 7 A shifting protrusion 250 is provided on the side of the sealing member 200 away from the liquid storage member 100 , and the protruding direction of the shifting protrusion 250 is perpendicular to the moving direction of the sealing member 200 .
[0064] In this embodiment, the moving protrusion 250 can be used by the user to apply force, for example, along Figure 2 The protrusion 250 is pushed rightward in the middle X direction, thereby causing the sealing member 200 and the liquid storage member 100 to move relative to each other.
[0065] For further information, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 The sealing member 200 is a plate-shaped structure, the injection hole 110 and the limiting groove 130 are located on the same surface of the liquid storage member 100 , and the sealing member 200 is movably connected to the liquid storage member 100 .
[0066] In this embodiment, the seal 200 can be Figure 2 Push in the left and right directions to complete the sealing and exposure of the injection hole 110.
[0067] For further information, please refer to Figure 9 In the figure, the Z direction is the up-down direction, and the X direction is the left-right direction. The injection hole 110 and the limiting groove 130 are respectively arranged on two mutually perpendicular surfaces of the liquid storage part 100; the sealing member 200 includes a first sub-seal 201 and a second sub-seal 202 which are perpendicular to each other. The second sub-seal 202 is provided with a limiting protrusion 210 and is movably connected to the liquid storage part 100 to increase or decrease the distance between the first sub-seal 201 and the injection hole 110.
[0068] In this embodiment, the first guiding groove 141, the second guiding groove 142, and the limiting groove 130 of the liquid storage member 100 are all provided on the right surface of the liquid storage member 100. At this time, the second sub-sealing member 202 is provided with structures such as a guiding protrusion 240 and a limiting protrusion 210. The sealing member 200 can move in the up and down direction to sequentially bring the first sub-sealing member 201 closer to or farther away from the liquid injection hole 110, thereby realizing the sealing and exposure of the liquid injection hole 110.
[0069] Further, please refer to Figure 10 , the sealing member 200 is rotatably connected to the liquid storage member 100, and the limiting groove 130 is arc-shaped, and the shape and size of the limiting protrusion 210 are adapted to the limiting groove 130.
[0070] In this embodiment, both the limiting protrusion 210 and the limiting groove 130 are arc-shaped structures, and the size of the limiting protrusion 210 is equal to or slightly smaller than that of the limiting groove 130. Therefore, when the sealing member 200 rotates relative to the liquid storage member 100, the limiting protrusion 210 can move relative to the limiting groove 130, and still can realize the position limitation of the sealing member 200 to prevent the sealing member 200 from slipping off.
[0071] It should be understood that the sealing member 200 may be provided with a rotating shaft 203, and the liquid storage member 100 is provided with a through hole 101. The rotating shaft 203 is inserted into the through hole 101 to realize the rotatable connection between the sealing member 200 and the liquid storage member 100.
[0072] Correspondingly, the present application also provides an aerosol generating device, and the aerosol generating device includes the liquid storage structure 10 in any one of the above embodiments.
[0073] In this embodiment, since the aerosol generating device includes the liquid storage structure 10 in any one of the above embodiments, and the liquid storage member 100 is provided with a limiting groove 130, and the limiting protrusion 210 is located in the limiting groove 130, when the sealing member 200 moves to a certain extent, the limiting protrusion 210 will abut against the inner wall of the limiting groove 130. At this time, the sealing member 200 cannot move further. That is, the cooperation between the limiting groove 130 and the limiting protrusion 210 realizes the limitation of the movement degree of the sealing member 200 relative to the liquid storage member 100, thereby preventing the sealing member 200 from falling off the liquid storage member 100.
[0074] It can be understood that the aerosol generating devices in the above embodiments include but are not limited to devices such as aromatherapy machines, drug atomizers, fire sprinkler systems, cleaning equipment, irrigation equipment, beauty instruments, and laboratory solute extraction equipment. Structures such as the elastic protrusion 230 and the sealing protrusion 220 in the above sealing member 200 can be Figure 1 as shown in, a silicone structure 20 formed integrally, having a certain elasticity.
