Description

Technical Field

[0001] This utility model relates to the technical field of atomizers, and in particular to an atomizing cartridge and an electronic atomizer. Background Technology

[0002] The atomizing cartridge is the core component of an electronic atomizer. The atomizing cartridge consists of an atomizing chamber and a liquid storage chamber connected to each other. The liquid storage chamber is used to store the liquid to be atomized. The atomizing chamber includes absorbent cotton and atomizing core. The absorbent cotton is responsible for drawing the liquid to be atomized from the liquid storage chamber, while the atomizing core is used to receive the liquid from the absorbent cotton and atomize the liquid by heating it.

[0003] Existing technology typically involves placing a normally closed, easily puncturable silicone component and a liquid-guiding needle between the atomizing chamber and the liquid reservoir. When the atomizing cartridge is not activated, the liquid-guiding needle is separated from the silicone component, and the easily puncturable portion is closed, thus preventing the liquid in the liquid reservoir from flowing into the atomizing chamber. When the atomizing cartridge is activated, pressing brings the atomizing chamber and the liquid reservoir closer together, causing the liquid-guiding needle to puncture the easily puncturable portion of the silicone component, thereby opening the channel so that the liquid to be atomized in the liquid reservoir can flow into the atomizing chamber and be absorbed by the absorbent cotton.

[0004] However, in the existing design, the liquid-guiding needle does not extend into the absorbent cotton when the atomizing bullet is activated. This results in a lack of effective guidance and adsorption of the liquid to be atomized during delivery, leading to insufficient liquid supply speed to the absorbent cotton and potentially causing it to burn out. Therefore, the existing atomizing bullet needs to be improved to enhance the liquid supply efficiency of the absorbent cotton.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0006] This utility model provides an atomizing cartridge and an electronic atomizer, mainly solving the technical problem of how to improve the liquid supply efficiency of the absorbent cotton in the atomizing chamber to prevent the absorbent cotton from burning dry.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An atomizing bullet includes an atomizing chamber, a liquid storage chamber, and a liquid guiding needle;

[0009] The liquid guiding needle is disposed between the atomizing chamber and the liquid storage chamber. One of the atomizing chamber and the liquid storage chamber is provided with an elastic, normally closed, easily punctured part that is not subjected to external force, and the liquid guiding needle is fixed on the other. The atomizing chamber is provided with absorbent cotton for receiving the liquid to be atomized in the liquid storage chamber.

[0010] When the liquid-guiding needle punctures the easily punctured portion, the liquid to be atomized in the reservoir can flow along the liquid-guiding needle into the atomizing chamber, which is the activated state of the atomizing bullet; when the liquid-guiding needle is away from the easily punctured portion and the easily punctured portion is in a closed state, the liquid to be atomized in the reservoir cannot flow into the atomizing chamber, which is the inactive state of the atomizing bullet;

[0011] At least when the atomizing bullet is in the activated state, the liquid guiding needle is inserted into the liquid-absorbing cotton.

[0012] In one of the technical solutions, the liquid storage chamber has a puncture-prone part on the side facing the atomizing chamber, the liquid guiding needle is fixedly connected to the atomizing chamber, the absorbent cotton has an insertion hole, and the liquid guiding needle is inserted into the insertion hole.

[0013] In one of the technical solutions, a liquid guiding channel is provided inside the liquid guiding needle. When the atomizing bullet is in an activated state, the liquid guiding channel connects the liquid storage chamber and the atomizing chamber.

[0014] The liquid guiding needle includes a first end and a second end opposite to each other. The first end is away from the atomizing chamber and is used to puncture the easily punctured part. The second end is inserted into the insertion hole and into the middle region of the absorbent cotton. The liquid guiding channel passes through the first end and does not pass through the second end. The outer wall of the second end is provided with at least one liquid outlet hole that extends into the liquid guiding channel.

[0015] In one of the technical solutions, the liquid guiding needle is provided with at least one liquid inlet on the outer wall of the first end, which extends into the liquid guiding channel. The liquid storage chamber is provided with a liquid storage room. When the atomizing bullet is in the activated state, the liquid storage room is connected to the liquid inlet, and the lowest point of the liquid inlet is not higher than the bottom surface of the liquid storage room.

[0016] In one of the technical solutions, the absorbent cotton is provided with the insertion hole at both opposite ends, the atomizing bullet includes two liquid guiding pins, the two liquid guiding pins are inserted into the two insertion holes one by one, and the second end of the two liquid guiding pins is provided with a liquid outlet, and the first end of the two liquid guiding pins is provided with a liquid inlet.

[0017] In one of the technical solutions, the liquid storage tank includes a liquid storage shell, a silicone component, a first fixing component, and a second fixing component;

[0018] The liquid storage shell has an open liquid storage chamber. The silicone component, the first fixing component, and the second fixing component are all located at the opening of the liquid storage chamber. The silicone component is used to block the opening of the liquid storage chamber. The silicone component has an easily puncturable part. The silicone component is disposed between the first fixing component and the second fixing component. The inner wall of the liquid storage chamber has a protruding limiting surface. The second fixing component is fixedly connected to the liquid storage shell, and the second fixing component compresses the silicone component. The silicone component is pushed by the force of the second fixing component to push the first fixing component against the limiting surface.

[0019] Let the plane of the first fixing member facing away from the silicone member be the first plane. When the atomizing bullet is in the activated state, the lowest point of the liquid inlet is not higher than the first plane.

[0020] In one of the technical solutions, the atomizing bullet further includes a splicing component, which is used to splice between the atomizing chamber and the liquid storage chamber. When the splicing component is connected between the atomizing chamber and the liquid storage chamber, the atomizing bullet is in an inactive state. When the splicing component is removed and the atomizing chamber and the liquid storage chamber are spliced ​​together, the atomizing bullet is in an active state.

[0021] In one of the technical solutions, the splicing component is a silicone component with a mating hole. When the atomizing bullet is in an inactive state, the splicing component is snapped into the liquid storage tank, and the liquid guiding pin is inserted into the mating hole. When the atomizing bullet is in an active state, the atomizing tank is snapped into the liquid storage tank.

[0022] In one of the technical solutions, the atomizing chamber includes an atomizing shell, the absorbent cotton, and the atomizing core;

[0023] The atomizing housing is provided with an atomizing chamber, in which the absorbent cotton and the atomizing core are housed. The atomizing core includes a hollow tube, atomizing cotton, and a heating wire. The hollow tube passes through the absorbent cotton, and the atomizing cotton passes through the hollow tube. A through hole is provided on the outer wall of the hollow tube, through which the atomizing cotton receives the liquid to be atomized from the absorbent cotton. The heating wire is in contact with the atomizing cotton. An air inlet is also provided on the outer wall of the hollow tube. A suction channel communicating with the outside is provided on the liquid storage chamber. The air inlet is connected to both the suction channel and the atomizing chamber. A clearance hole is provided on the outer wall of the atomizing housing, penetrating into the atomizing chamber. The liquid guiding pin is fixedly connected to the atomizing housing and inserted into the absorbent cotton through the clearance hole.

[0024] This application also provides an electronic atomizer, including a power supply unit and the aforementioned atomizing cartridge, wherein the atomizing chamber is electrically connected to the power supply unit.

[0025] Compared with the prior art, the atomizing bullet provided by this utility model has at least the following beneficial effects:

[0026] This design incorporates a liquid-guiding needle that extends into the absorbent cotton within the atomizing chamber at least when the atomizing cartridge is activated. Due to the porous structure and strong adsorption properties of the absorbent cotton, when the atomizing cartridge is activated, the liquid to be atomized in the storage chamber is subjected to both its own gravity and the suction force of the absorbent cotton. This allows the liquid to flow rapidly along the liquid-guiding needle into the absorbent cotton under the combined effect of gravity and suction, enabling the absorbent cotton to quickly absorb and store the liquid. In other words, using this atomizing cartridge, the liquid to be atomized can reach the absorbent cotton quickly and stably, providing a sufficient liquid supply and preventing the absorbent cotton from burning dry.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Please refer to the following: Figures 1 to 5 This utility model provides an atomizing bullet, which mainly includes a liquid storage chamber 1, an atomizing chamber 2, and a liquid guiding needle 3. The atomizing chamber 2 includes absorbent cotton 22 placed inside, which receives the liquid to be atomized from the liquid storage chamber 1. When the absorbent cotton 22 is heated, it can achieve the function of liquid atomization. The liquid guiding needle 3 is disposed between the atomizing chamber 2 and the liquid storage chamber 1. One of the atomizing chamber 2 and the liquid storage chamber 1 is provided with a puncture-prone part 10, and the liquid guiding needle 3 is fixed on the other. The puncture-prone part 10 is elastic and is normally closed when not subjected to external force. More specifically, when the liquid guiding needle 3 punctures the easily puncturable part 10, the liquid to be atomized in the liquid storage chamber 1 can flow along the liquid guiding needle 3 into the atomizing chamber 2, which is the activated state of the atomizing bullet; when the liquid guiding needle 3 is away from the easily puncturable part 10 and the easily puncturable part 10 is in a closed state, the liquid to be atomized in the liquid storage chamber 1 cannot flow into the atomizing chamber 2, which is the inactive state of the atomizing bullet; Figures 1 to 3 These are structural diagrams of the atomizing bomb in its activated state. Figure 7 and Figure 8 The diagram shown is of the atomizing bomb in its inactive state. Figure 3 As shown, at least when the atomizing bomb is in the activated state, the liquid guiding needle 3 is inserted into the liquid-absorbing cotton 22.

[0047] Specifically, this design involves inserting the liquid-guiding needle 3 into the absorbent cotton 22 of the atomizing chamber 2 at least when the atomizing bullet is in the activated state. Because the absorbent cotton 22 has a porous structure and strong adsorption capacity, when the atomizing bullet is activated, the liquid to be atomized in the storage chamber 1 is subjected to both its own gravity and the suction force of the absorbent cotton 22. This allows the liquid to be atomized in the storage chamber 1 to flow rapidly into the absorbent cotton 22 along the liquid-guiding needle 3 under the combined effect of its own gravity and suction force. This enables the absorbent cotton 22 to quickly absorb and store the liquid to be atomized. In other words, using the atomizing bullet of this design, the liquid to be atomized can quickly and stably reach the absorbent cotton 22, providing a sufficient liquid supply and preventing the absorbent cotton 22 from burning dry.

[0048] Please refer to the following: Figures 2 to 5 In this embodiment, the aforementioned easily puncturable portion 10 is preferably provided on the side of the liquid storage chamber 1 facing the atomizing chamber 2. Correspondingly, in this embodiment, the aforementioned liquid guiding needle 3 is preferably designed to be fixed on the atomizing chamber 2. In fact, the absorbent cotton 22 is provided with an insertion hole 221. Since the liquid guiding needle 3 is fixed on the atomizing chamber 2, the liquid guiding needle 3 is always inserted into the insertion hole 221 of the absorbent cotton 22, regardless of whether the atomizing bullet is in an activated or deactivated state. Using this technical solution, when the atomizing bullet is in the deactivated position, the easily puncturable portion 10 blocks the liquid storage chamber 1, so the liquid to be atomized in the liquid storage chamber 1 will not automatically leak downwards.

[0049] In another technical solution, the liquid-guiding needle 3 can also be designed to be fixed to the liquid storage chamber 1. Correspondingly, the side of the atomizing chamber 2 facing the liquid storage chamber 1 needs to be provided with the aforementioned easily puncturable part 10. Using this solution, the atomizing chamber 2 and the liquid storage chamber 1 can be moved closer or further apart, enabling the atomizing bullet to switch between active and inactive states. With this technical solution, since the liquid-guiding needle 3 is fixed to the liquid storage chamber 1, the liquid-guiding needle 3 always contains liquid to be atomized. Therefore, this technical solution also requires sealing the gap between the outer wall of the liquid-guiding needle 3 and the atomizing chamber 2 to prevent the liquid to be atomized in the liquid storage chamber 1 from leaking along the gap between the liquid-guiding needle 3 and the atomizing chamber 2 when the atomizing bullet is in the inactive position. Therefore, compared to the previous technical solution, this technical solution is structurally more complex.

[0050] Please refer to the following: Figures 3 to 5 The liquid-guiding needle 3 can be specifically understood as having an internal liquid-guiding channel 30. When the atomizing bullet is activated, the liquid-guiding channel 30 connects the liquid storage chamber 1 and the atomizing chamber 2, allowing the liquid to be atomized in the liquid storage chamber 1 to flow into the absorbent cotton 22. Specifically, the liquid-guiding needle 3 includes a first end 31 and a second end 32. The first end 31 extends away from the atomizing chamber 2. In fact, the first end 31 is used to pierce the easily punctured part 10, and the second end 32 is used to insert into the aforementioned insertion hole 221. More specifically, this design places the second end 32 into the middle region of the absorbent cotton 22, and the liquid-guiding channel 30 is designed to penetrate the first end 31 but not the second end 32. At least one liquid outlet hole 33 is provided on the outer wall of the second end 32 of the liquid-guiding needle 3, and this liquid outlet hole 33 extends into the liquid-guiding channel 30. This design allows the liquid to be atomized in the storage chamber 1 to flow sequentially along the liquid guiding channel 30 and the liquid outlet 33 into the central area of ​​the absorbent cotton 22 when the atomizing bullet is activated. The flow of the liquid to be atomized from the central area of ​​the absorbent cotton 22 helps the absorbent cotton 22 absorb the liquid to be atomized more quickly, thereby further preventing the absorbent cotton 22 from dry burning.

[0051] Please refer to the following: Figures 2 to 4 The absorbent cotton 22 has insertion holes 221 at both opposite ends. Correspondingly, the atomizing cartridge includes two liquid-guiding pins 3, which are inserted into the two insertion holes 221 one-to-one. The second ends 32 of both liquid-guiding pins 3 are provided with liquid outlet holes 33. Furthermore, the liquid storage chamber 1 has two easily puncturable portions 10. This design allows the liquid to be atomized in the storage chamber 1 to flow from the two liquid-guiding pins 3 to the opposite ends of the middle region of the absorbent cotton 22 when the atomizing cartridge is activated. This further improves the efficiency of the absorbent cotton 22 in absorbing the liquid to be atomized, thereby further preventing the absorbent cotton 22 from dry-burning.

[0052] Please refer to it again. Figure 5 The liquid guiding needle 3 has at least one liquid inlet 34 on the outer wall of its first end 31. This liquid inlet 34 extends into the liquid guiding channel 30. The liquid storage tank 1 is provided with a liquid storage chamber 111. Please refer to [link / reference]. Figure 3 When the atomizing bomb is activated, the liquid storage chamber 111 and the liquid inlet 34 are connected, and the lowest point of the liquid inlet 34 is not higher than the bottom surface of the liquid storage chamber 111, so that the liquid to be atomized at the bottom of the liquid storage chamber 111 can also flow into the atomizing chamber 2 along the liquid guiding channel 30. The outer diameter of the liquid guiding needle 3 is 1.5mm-2mm, preferably 1.8mm; the width of the liquid inlet 34 is 0.4mm-0.8mm, preferably 0.6mm; and the diameter of the liquid outlet 33 is 0.4mm-1.2mm, preferably 0.5mm.

[0053] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 6The liquid storage chamber 1 specifically includes a liquid storage shell 11 and a silicone component 12. The liquid storage shell 11 contains an open liquid storage chamber 111. The silicone component 12 is located at the opening of the liquid storage chamber 111 and is used to block the opening to prevent the liquid to be atomized from leaking downwards. The silicone component 12 has the aforementioned easily puncturable portion 10. In other words, in this embodiment, the silicone component 12, in addition to sealing the liquid storage chamber 111, also facilitates the formation of the normally closed easily puncturable portion 10, thereby simplifying the structure of the atomizing bullet. Considering that the silicone component 12 may shift inwards due to friction during the insertion of the liquid-guiding needle 3 into the easily puncturable portion 10, and also considering that the silicone component 12 may shift outwards due to friction during the withdrawal of the liquid-guiding needle 3 relative to the silicone component 12, this shifting of the silicone component 12 could cause the liquid to be atomized in the liquid storage chamber 111 to leak downwards. Based on this, the liquid storage chamber 1 of this embodiment further includes a first fixing member 13 and a second fixing member 14. Both the first fixing member 13 and the second fixing member 14 are located at the opening of the liquid storage chamber 111. The silicone component 12 is specifically disposed between the first fixing member 13 and the second fixing member 14. A limiting surface 112 protrudes from the inner wall of the liquid storage chamber 111. The second fixing member 14 is fixedly connected to the liquid storage shell 11. Furthermore, the second fixing member 14 compresses the silicone component 12 to ensure that the silicone component 12 can reliably seal the liquid storage chamber 111. The silicone component 12, under the force of the second fixing member 14, pushes the first fixing member 13 to abut against the limiting surface 112. By providing the first fixing member 13 and the second fixing member 14, the silicone component 12 can be restricted to a designated position. When the liquid guiding needle 3 inserts into or pulls out of the silicone component 12, the silicone component 12 will not shift, thereby ensuring that the silicone component 12 can reliably seal the liquid storage chamber 111. Preferably, the surface of the liquid storage shell 11 is provided with a first slot 113, and the buckle on the second fixing member 14 is embedded in the first slot 113 to achieve a fixed connection with the liquid storage shell 11.

[0054] Please see Figure 3 Let the plane of the first fixing member 13 facing away from the silicone member 12 be the first plane 131. This first plane 131 is understood as the bottom surface of the liquid storage chamber 111. That is, when the atomizing bullet is in the activated state, the lowest point of the liquid inlet 34 is not higher than the first plane 131.

[0055] Please see Figure 6 The second fixing member 14 is provided with a liquid injection hole 141. The liquid injection hole 141 passes through the silicone member 12 and the first fixing member 13 in sequence to connect to the liquid storage chamber 111. The liquid to be atomized can be added to the liquid storage chamber 111 through this liquid injection hole 141. Based on this, the liquid storage chamber 1 of this embodiment also includes a liquid injection plug 16. The liquid injection plug 16 blocks the liquid injection hole 141 to prevent the liquid to be atomized in the liquid storage chamber 111 from leaking out from the liquid injection hole 141.

[0056] Please refer to the following: Figure 7 and Figure 8 The atomizing cartridge also includes a connecting piece 4, which is used to connect between the atomizing chamber 2 and the liquid storage chamber 1 to separate them. When the connecting piece 4 is connected between the atomizing chamber 2 and the liquid storage chamber 1, the liquid guiding needle 3 cannot be inserted into the easily puncturable part 10 of the liquid storage chamber 1 due to the obstruction of the connecting piece 4, and the atomizing cartridge is in an inactive state at this time. When the connecting piece 4 is removed, and the atomizing chamber 2 and the liquid storage chamber 1 are connected to each other, the liquid guiding needle 3 is inserted into the easily puncturable part 10 of the liquid storage chamber 1, and the atomizing cartridge is in an active state at this time. Preferably, the connecting piece 4 is designed as a silicone component with a certain degree of elasticity, so that the user can more easily install the connecting piece 4 between the liquid storage chamber 1 and the atomizing chamber 2, and at the same time, the user can more easily remove the connecting piece 4, thereby facilitating the user to switch the atomizing cartridge between the active and inactive states. More preferably, the splicing component 4 is provided with mating holes 41, the number of which is the same as the number of liquid guiding pins 3. When the atomizing bullet is in an inactive state, the first buckle 42 on the splicing component 4 is engaged into the second slot 114 of the liquid storage shell 11 to achieve a snap-fit ​​connection between the splicing component 4 and the liquid storage chamber 1. At the same time, the liquid guiding pins 3 connected to the atomizing chamber 2 are inserted into the mating holes 41 of the splicing component 4. When the atomizing bullet is in an active state, the second buckle 212 on the atomizing chamber 2 is engaged into the second slot 114 of the liquid storage shell 11 to achieve a snap-fit ​​connection between the atomizing chamber 2 and the liquid storage chamber 1.

[0057] Please refer to the following: Figure 3 and Figure 4The atomizing chamber 2 mainly includes an atomizing shell 21, absorbent cotton 22, and atomizing core 23. The atomizing shell 21 contains an atomizing chamber 211, within which the absorbent cotton 22 and atomizing core 23 are housed. The atomizing core 23 specifically includes a hollow tube 231, atomizing cotton 232, and a heating wire 233. The hollow tube 231 passes through the absorbent cotton 22, and the atomizing cotton 232 passes through the hollow tube 231. A through-hole (not shown in the figure) is provided on the outer wall of the hollow tube 231, through which the atomizing cotton 232 receives the liquid to be atomized from the absorbent cotton 22. The heating wire 233 contacts the atomizing cotton 232; when the heating wire 233 heats up, it atomizes the liquid absorbed by the atomizing cotton 232. The adsorbed liquid is atomized. In addition, an air inlet 2311 is provided on the outer wall of the hollow tube 231. The liquid storage chamber 1 is provided with a suction channel 15 that communicates with the outside. When the user inhales into the suction channel 15, the liquid atomized in the atomizing chamber 2 flows outward from the suction channel 15 so that the user can draw in the atomized liquid. The air inlet 2311 is connected to the suction channel 15 and the atomizing chamber 211 respectively, so that outside air can enter the liquid storage chamber 111 in sequence from the suction channel 15, the air inlet 2311, the atomizing chamber 211, and the liquid guiding channel 30, thereby replenishing the air in the liquid storage chamber 111 and ensuring that the liquid to be atomized in the liquid storage chamber 111 can automatically flow into the atomizing chamber 2 due to its own weight. In addition, an allowance hole 213 is provided on the outer wall of the atomizing housing 21, extending into the atomizing chamber 211. The aforementioned liquid guiding needle 3 is actually fixedly connected to the atomizing housing 21, and the liquid guiding needle 3 is inserted into the absorbent cotton 22 through the allowance hole 213. Preferably, the liquid guiding needle 3 is fixedly connected to the atomizing housing 21 by a snap-fit ​​connection.

[0058] This embodiment also provides an electronic atomizer, which mainly includes a power supply unit (not shown in the figure) and the aforementioned atomizing cartridge. The atomizing chamber 2 of the atomizing cartridge is electrically connected to the power supply unit, enabling the power supply unit to provide power to the atomizing core 23 inside the atomizing cartridge. Since the electronic atomizer of this embodiment uses the aforementioned atomizing cartridge, it also has the advantages of strong liquid absorption capacity and low risk of dry burning.

[0059] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
