Description

Technical Field

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

[0002] Current electronic atomizers mainly consist of an atomizing unit and a liquid reservoir. The reservoir stores the liquid to be atomized, while the atomizing unit receives the liquid from the reservoir and atomizes it. Currently, most electronic atomizers maintain a continuous connection between the atomizing unit and the liquid reservoir after manufacturing. This can lead to several problems. Firstly, it causes the flavor of the liquid to be atomized to be lost, and it can also cause the atomizing unit to become oversaturated with the liquid, leading to aging and a burnt taste on first use. Secondly, during transportation and when not in use, electronic atomizers are susceptible to leakage due to vibration, temperature changes, or fluctuations in air pressure. This phenomenon is known in the industry as "oil leakage." Oil leakage not only wastes the liquid to be atomized and contaminates the device, but also reduces the user experience. To address the aforementioned issues, current electronic atomizers design the liquid reservoir to have a first position and a second position relative to the atomizing unit after assembly. When the liquid reservoir is in the first position, the liquid outlet channel of the sealing cap on the reservoir is blocked, preventing the liquid from flowing from the reservoir into the atomizing unit. This working state is also known as the inactive state, preventing leakage of the liquid to be atomized from the reservoir. When the liquid reservoir is switched to the second position, the liquid inside the reservoir can flow from the liquid outlet channel on the sealing cap into the atomizing unit, enabling the atomizing unit to receive the liquid and atomize it. This working state is also known as the active state. However, current e-cigarettes lack the ability to adjust the efficiency of the liquid supply from the reservoir to the atomizer. As the liquid inside the reservoir is gradually consumed, the internal pressure decreases, resulting in a slower and slower supply of liquid to the atomizer. When the supply is too slow, the atomizer is prone to dry burning. Therefore, how to adjust the liquid supply efficiency of the reservoir in e-cigarettes, which have both active and inactive states, is a technical challenge that e-cigarettes urgently need to overcome.

[0003] 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

[0004] This utility model provides an electronic atomizer, which mainly solves the technical problem of how to reliably adjust the liquid supply efficiency of the liquid reservoir based on the design of an electronic atomizer with active and inactive states.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electronic atomizer includes an atomizing main unit and a liquid storage chamber that is inserted into the atomizing main unit along a first direction. The liquid storage chamber includes a liquid storage shell, a sealing cap, and a limiting shell. A liquid storage chamber is provided inside the liquid storage shell. The sealing cap seals the opening of the liquid storage chamber and is provided with a liquid outlet channel communicating with the liquid storage chamber. The limiting shell is disposed at the opening of the liquid storage chamber and is fixedly connected to the liquid storage shell.

[0007] The liquid storage shell has a first position, a second position, and a third position arranged sequentially along a first direction relative to the atomizing host. When the liquid storage shell is in the first position, the liquid outlet channel is blocked so that the liquid storage chamber is not connected to the atomizing host. When the liquid storage shell is in the second and third positions, the liquid outlet channel is open so that the liquid storage chamber is connected to the atomizing host. When the liquid storage shell switches between the first and second positions, the sealing cover is restricted by the limiting shell and moves synchronously with the liquid storage shell. When the liquid storage shell moves from the second position to the third position, the sealing cover is released from the limiting shell by the reaction force of the atomizing host so that it can move in a straight line relative to the liquid storage shell in the first direction.

[0008] In one of the technical solutions, the limiting shell is sleeved around the sealing cover, and one of the inner ring of the limiting shell and the outer wall of the sealing cover is provided with a protruding limiting buckle, while the other is provided with a limiting groove.

[0009] When the liquid storage shell switches between the first position and the second position, the limiting buckle is always embedded in the limiting groove; when the liquid storage shell moves from the second position to the third position, the sealing cover is subjected to the reaction force of the atomizing host, causing the limiting buckle to disengage from the limiting groove.

[0010] In one technical solution, the sealing cap has a first protrusion protruding along the first direction at the end facing away from the liquid storage chamber. The liquid outlet channel passes through the first protrusion along the first direction. The surface of the atomizing host has a second protrusion protruding in the opposite direction of the first direction. The second protrusion is inserted into the liquid outlet channel. A sealing ring is connected between the hole wall of the liquid outlet channel and the outer wall of the second protrusion. The limiting shell is sleeved around the first protrusion. The outer wall of the first protrusion has a limiting buckle or a limiting groove. The atomizing host has a support surface on the outside of the second protrusion. When the first protrusion does not abut against the support surface, the limiting buckle is always embedded in the limiting groove. When the first protrusion abuts against the support surface and presses down on the liquid storage shell along the first direction, the sealing cap is subjected to the reaction force of the support surface, causing the limiting buckle to disengage from the limiting groove.

[0011] In one of the technical solutions, a liquid guiding pin is fixed on the second protrusion and extends into the liquid outlet channel. The liquid guiding pin is provided with a through liquid guiding hole. The atomizing host is provided with a connected atomizing chamber and a liquid guiding channel. The end of the liquid guiding channel away from the atomizing chamber is connected to the liquid guiding hole.

[0012] When the liquid storage shell is in the first position, the liquid guiding needle is housed in the liquid outlet channel and the liquid outlet channel is blocked; when the liquid storage shell is in the second and third positions, the liquid guiding needle passes over the liquid outlet channel and extends into the liquid storage chamber.

[0013] In one of the technical solutions, the liquid storage tank also includes an elastic element and a slider;

[0014] The slider and the sealing cap are slidably connected in the first direction. The elastic element is connected between the slider and the sealing cap. The slider is subject to the elastic force of the elastic element and has a tendency to move in the first direction. The liquid guiding needle is located in the first direction of the slider. When the liquid storage shell is in the first position, the slider blocks the inner wall of the liquid outlet channel. When the liquid storage shell is in the second position and the third position, the slider is pushed in the opposite direction of the first direction by the liquid guiding needle and the liquid outlet channel is opened.

[0015] In one of the technical solutions, the sealing cap has at least one first notch on a portion of the outer side wall of the liquid storage chamber, and the liquid guiding needle has at least one second notch on the outer side wall near the slider. Both the first notch and the second notch are connected to the liquid outlet channel. When the liquid storage shell is in the second position and the third position, the liquid storage chamber, the first notch, the liquid outlet channel, the second notch and the liquid guiding hole are connected in sequence.

[0016] In one of the technical solutions, the sealing cover includes a sealing shell and a sealing soft rubber sleeved on one end of the sealing shell;

[0017] The sealing soft rubber is interference-fitted with the liquid storage chamber and can move relative to the liquid storage shell in a straight line along the first direction. The sealing shell has a first protruding post at one end facing away from the sealing soft rubber. The liquid outlet channel and the first notch are both provided on the sealing shell. The slider and the sealing shell are slidably connected in a straight line along the first direction. The elastic element is provided between the slider and the sealing shell.

[0018] In one technical solution, the atomizing host includes an atomizing shell, an atomizing core housed within the atomizing shell, and a battery. The battery is electrically connected to the atomizing core, which is housed within the atomizing chamber. The atomizing core atomizes liquid when energized and heated. The atomizing shell also has a mist outlet channel, one end of which connects to the atomizing chamber, and the other end of which connects to the outside. The atomizing shell is provided with a second protrusion, the atomizing chamber, and the liquid guiding channel.

[0019] In one of the technical solutions, the limiting shell is fixedly connected to the liquid storage shell by a snap-fit ​​connection.

[0020] In one of the technical solutions, when the liquid storage shell is in the first position and the third position relative to the atomizing host, the liquid storage shell is snap-fitted to the atomizing host.

[0021] Compared with the prior art, the electronic atomizer provided by this utility model has at least the following beneficial effects:

[0022] This electronic atomizer retains the ability of the reservoir shell to switch between a first and a second position. That is, it preserves the atomizer's ability to switch between inactive and active states, preventing flavor loss and leakage during transport or when not in use. Based on this, the atomizer also designs the reservoir shell to have a third position relative to the atomizer unit, and designs the sealing cap to move in the opposite direction to the first direction relative to the reservoir shell as it moves from the second position to the third position. This achieves the purpose of compressing the liquid storage chamber with the sealing cover. By compressing the liquid storage chamber with the sealing cover, the air pressure in the liquid storage chamber can be increased. The higher the air pressure in the liquid storage chamber, the better the liquid supply efficiency of the liquid storage chamber. In other words, this solution can adjust the air pressure in the liquid storage chamber by moving the liquid storage shell between the second and third positions, thereby realizing the function of adjustable liquid supply efficiency of the liquid storage chamber. Especially when the liquid inside the liquid storage chamber is consumed in large quantities, resulting in low air pressure inside the liquid storage chamber, the liquid storage shell can be switched to the third position to increase the internal air pressure of the liquid storage chamber, thereby reducing the risk of dry burning of the atomizing host. Furthermore, the limiting shell set in this solution can ensure that the internal air pressure of the liquid storage chamber can be adjusted by the sealing cover while the liquid outlet channel on the sealing cover is connected to the atomizing host. This avoids the phenomenon that the sealing cover compresses the liquid storage chamber while the liquid outlet channel on the sealing cover remains blocked during the process of the liquid storage shell moving in the first position in the first direction, which would prevent the liquid storage chamber from connecting with the atomizing host. Thus, the electronic atomizer can reliably achieve the purpose of adjustable liquid supply efficiency while having both inactive and active states. Attached Figure Description

[0036] 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.

[0037] Please refer to the following: Figures 1 to 5 This embodiment provides an electronic atomizer, which mainly includes an atomizing main unit 1 and a liquid storage tank 2. The liquid storage tank 2 is inserted into the atomizing main unit 1 along the first direction Z. The liquid storage tank 2 mainly includes a liquid storage shell 21 and a sealing cap 22. The liquid storage shell 21 is provided with a liquid storage chamber 211 for storing liquid to be atomized. The atomizing main unit 1 is used to receive the liquid to be atomized from the liquid storage chamber 211 and atomize the liquid. The sealing cap 22 is used to seal the opening of the liquid storage chamber 211 to prevent the liquid in the liquid storage chamber 211 from leaking out. The sealing cap 22 is provided with a liquid outlet channel 223, which communicates with the liquid storage chamber 211. Specifically, when the liquid storage tank 2 is inserted into the atomizing main unit 1 along the first direction Z, the liquid storage shell 21 has a first position, a second position, and a third position sequentially arranged along the first direction Z relative to the atomizing main unit 1. Figure 1 The diagram shows the internal structure of the electronic atomizer when the liquid reservoir 21 is in the first position. Figure 2 The diagram shows the internal structure of the electronic atomizer when the liquid reservoir 21 is in the second position. Figure 3 The diagram shows the internal structure of the electronic atomizer when the reservoir 21 is in the third position. When the reservoir 21 is in the third position... Figure 1When the device is in the first position, the atomizing host 1 is far from the liquid outlet channel 223 and the liquid outlet channel 223 is blocked, so that the liquid storage chamber 211 cannot be connected to the atomizing host 1. At this time, it can also be understood that the electronic atomizer is in an inactive state. When the liquid storage shell 21 is in any position between the second and third positions, the atomizing host 1 crosses the liquid outlet channel 223 and extends into the liquid storage chamber 211. At this time, the liquid outlet channel 223 is equivalent to being in an open state. At this time, the liquid storage chamber 211 and the atomizing host 1 are connected to each other. At this time, it can also be understood that the electronic atomizer is in an active state. In addition, the sealing cap 22 is designed to move along a straight line in the first direction Z relative to the liquid storage shell 21. Based on this, the liquid storage chamber 2 of this solution also includes a limiting shell 23. The limiting shell 23 is set at the opening of the liquid storage chamber 211 and is fixedly connected to the liquid storage shell 21 at points B and C by a snap-fit ​​connection. When the liquid storage shell 21 switches between the first position and the second position, the sealing cap 22 is restricted by the limiting shell 23 and moves synchronously with the liquid storage shell 21 along a straight line in the first direction Z. When the liquid storage shell 21 moves from the second position to the third position, the sealing cap 22 is released from the limitation of the limiting shell 23 by the reaction force of the atomizing host 1, so that the sealing cap 22 can move in the opposite direction of the first direction Z relative to the liquid storage shell 21, thereby realizing the function of the sealing cap 22 compressing the liquid storage chamber 211 upward.

[0038] Specifically, the atomizer in this design retains the function of the reservoir 21 being able to switch between a first position and a second position. That is, this design retains the function of the atomizer being able to switch between an inactive state and an active state, preventing the loss of flavor and leakage of the internal liquid during transportation or when not in use. Based on this, the atomizer in this design also designs the reservoir 21 to have a third position relative to the atomizing host 1, and designs the reservoir 21 to move from the second position to the third position in the first direction Z, causing the sealing cap 22 to move in the opposite direction of the first direction Z relative to the reservoir 21, thereby achieving the sealing cap 22... The purpose of compressing the liquid storage chamber 211 is to increase the air pressure in the liquid storage chamber 211 by compressing it through the sealing cover 22. The higher the air pressure in the liquid storage chamber 211, the better it is for improving the liquid supply efficiency of the liquid storage chamber 211. In other words, this solution can adjust the air pressure in the liquid storage chamber 211 by moving the liquid storage shell 21 between the second and third positions, thereby realizing the function of adjustable liquid supply efficiency of the liquid storage chamber 211. In particular, when the liquid inside the liquid storage chamber 211 is consumed in large quantities, resulting in low air pressure inside the liquid storage chamber 211, the liquid storage shell 21 can be switched to the third position to increase the internal air pressure of the liquid storage chamber 211, thereby reducing the risk of dry burning of the atomizing host 1. Furthermore, the limiting shell 23 set in this solution can ensure that the liquid storage chamber 211 is connected to the atomizing host 1 through the liquid outlet channel 223 on the sealing cover 22, and the internal air pressure of the liquid storage chamber 211 can be adjusted by the sealing cover 22. This avoids the phenomenon that the liquid storage chamber 211 cannot be connected to the atomizing host 1 when the sealing cover 22 compresses the liquid storage chamber 211 during the process of the liquid storage shell 21 moving in the first direction Z at the first position, but the liquid outlet channel 223 on the sealing cover 22 is still blocked. This allows the electronic atomizer to reliably achieve the purpose of adjustable liquid supply efficiency under the premise of having non-activated and activated states.

[0039] Please refer to the following: Figures 1 to 5When the liquid storage shell 21 is in the first position and the third position relative to the atomizing host 1, this embodiment designs the liquid storage shell 21 to be fixed to the atomizing host 1 by means of a snap-fit ​​connection, so as to ensure that the liquid storage shell 21 can be stably stationed in the first position and the third position. This solves the problem that the liquid storage shell 21 may accidentally move to the second position due to external force or vibration when it is in the first position. This ensures that the electronic atomizer will not switch from the inactive state to the active state during transportation and storage. At the same time, it also solves the problem that the liquid storage shell 21 may spontaneously move to the second position when it is in the third position due to the large internal force of the outward expansion of the internal liquid storage chamber 211. This helps to improve the stability of the liquid supply of the liquid storage shell 21 in the third position. Preferably, the outer wall of the liquid storage shell 21 is provided with a first slot 212 and a second slot 213, and the outer wall of the atomizing host 1 is provided with a protrusion 117. When the liquid storage shell 21 is in the first position, the protrusion 117 is embedded in the first slot 212, thereby locking the first position of the liquid storage shell 21; when the liquid storage shell 21 is in the third position, the protrusion 117 is embedded in the second slot 213, thereby locking the third position of the liquid storage shell 21.

[0040] Please refer to the following: Figure 1 and Figure 5 The limiting shell 23 is preferably designed to be sleeved on the periphery of the sealing cover 22, so that the limiting shell 23 can be housed in the liquid storage chamber 211, so that even if the limiting shell 23 is added to the liquid storage chamber 2, the thickness of the liquid storage chamber 2 in the first direction Z does not need to be increased. More specifically, one of the inner ring of the limiting shell 23 and the outer wall of the sealing cover 22 is provided with a protruding limiting buckle 231, and the other is provided with a limiting groove 221. In this embodiment, the limiting buckle 231 is provided on the inner ring of the limiting shell 23, and the limiting groove 221 is provided on the outer wall of the sealing cover 22. When the liquid storage shell 21 switches between the first position and the second position, the limiting buckle 231 is always embedded in the limiting groove 221. Since the limiting shell 23 with the limiting buckle 231 is always fixedly connected to the liquid storage shell 21, the sealing cover 22, after being restricted by the limiting buckle 231, always moves synchronously with the liquid storage shell 21 in the first direction Z, which is beneficial for the electronic atomizer to reliably switch between the inactive state and the active state. When the liquid storage shell 21 moves from the second position to the third position along the first direction Z, the sealing cover 22 is subjected to the reaction force of the atomizing host 1, causing the limiting buckle 231 to disengage from the limiting groove 221. After that, the sealing cover 22 is no longer restricted by the limiting shell 23. Therefore, as the liquid storage shell 21 continues to move along the first direction Z in the second position, the sealing cover 22 can move relative to the liquid storage shell 21 in the opposite direction of the first direction Z, thereby specifically realizing the purpose of the sealing cover 22 compressing the liquid storage chamber 211 when the liquid storage shell 21 moves from the second position to the third position.

[0041] Please refer to them again. Figure 1 , Figure 4 and Figure 5 The sealing cap 22 has a first protrusion 222 protruding along the first direction Z at the end facing away from the liquid storage chamber 211. The liquid outlet channel 223 actually passes through this first protrusion 222 along the first direction Z. The limiting shell 23 is actually sleeved around the first protrusion 222. The limiting buckle 231 or limiting groove 221 is actually provided on the outer wall of the first protrusion 222. The surface of the atomizing host 1 has a second protrusion 111 protruding in the opposite direction of the first direction Z. This second protrusion 111 is actually inserted into the liquid outlet channel 223, thereby realizing the function of the liquid storage chamber 2 and the atomizing host 1 being inserted into each other along the first direction Z. In order to prevent liquid from leaking outward from the gap between the inner wall of the liquid outlet channel 223 and the outer wall of the second protrusion 111, a sealing ring 113 is connected between the hole wall of the liquid outlet channel 223 and the outer wall of the second protrusion 111. Furthermore, the outer wall of the atomizing host 1 is provided with a support surface 112 on the outside of the second protrusion 111. When the first protrusion 222 does not abut against the support surface 112, the limiting buckle 231 is always embedded in the limiting groove 221. Only when the first protrusion 222 abuts against the support surface 112 and continues to press down on the liquid storage shell 21 in the first direction Z, the sealing cover 22 will be subjected to the reaction force of the support surface 112 and the limiting buckle 231 will be able to disengage from the limiting groove 221. This more specifically achieves the purpose of the sealing cover 22 compressing the liquid storage chamber 211 when the liquid storage shell 21 moves from the second position to the third position.

[0042] Please refer to the following: Figures 1 to 5 A liquid guiding pin 14 is fixed on the second protrusion 111. The liquid guiding pin 14 extends into the liquid outlet channel 223. A through liquid guiding hole 141 is provided in the liquid guiding pin 14. The atomizing host 1 is provided with a connected atomizing chamber 114 and a liquid guiding channel 115. The end of the liquid guiding channel 115 away from the atomizing chamber 114 is connected to the liquid guiding hole 141. When the liquid storage shell 21 is in the first position, the liquid guiding needle 14 is housed in the liquid outlet channel 223 and the liquid outlet channel 223 is blocked. At this time, the liquid in the liquid storage chamber 211 cannot flow into the liquid guiding needle 14 along the liquid outlet channel 223. When the liquid storage shell 21 is in the second and third positions, the liquid guiding needle 14 extends into the liquid storage chamber 211 after passing through the liquid outlet channel 223, so that the liquid in the liquid storage chamber 211 can flow into the liquid guiding hole 141 of the liquid guiding needle 14, and then the liquid can enter the atomization chamber 114 through the liquid guiding channel 115.

[0043] Please refer to the following: Figures 1 to 5The liquid storage tank 2 also includes an elastic element 24 and a slider 25. The slider 25 is slidably connected to the sealing cap 22 in the first direction Z within the liquid outlet channel 223. The elastic element 24 is preferably a spring, which is connected between the slider 25 and the sealing cap 22. The slider 25 has a tendency to move in the first direction Z after being subjected to the elastic force of the elastic element 24. The liquid guiding needle 14 is located in the first direction Z of the slider 25. When the liquid storage tank 21 is in the first position, the slider 25 blocks the inner wall of the liquid outlet channel 223 through the O-ring seal 251. When the liquid storage tank 21 moves from the first position to the second or third position in the first direction Z, the slider 25 is pushed in the opposite direction of the first direction Z by the liquid guiding needle 14. During this process, the slider 25 will compress the elastic element 24, which helps to keep the liquid outlet channel 223 in the open state. This design ensures better sealing of the liquid storage chamber 211 when the liquid storage shell 21 is in the first position, reducing the risk of leakage from the liquid storage chamber 211 to the outside through the liquid outlet channel 223. At the same time, this design also makes it easy to open the liquid outlet channel 223.

[0044] In another embodiment, a flexible, normally closed, easily puncturable portion can be provided inside or at the end of the liquid outlet channel 223. When the liquid storage shell 21 is in the first position, the easily puncturable portion is normally closed, thus blocking the liquid outlet channel 223. When the liquid storage shell 21 moves from the first position to the second position, the liquid guiding needle 14 punctures the easily puncturable portion in the opposite direction of the first direction Z, thus opening the liquid outlet channel 223. At this time, the liquid storage chamber 211 also achieves the purpose of supplying liquid to the atomizing host 1 through the liquid guiding needle 14.

[0045] Please refer to the following: Figures 1 to 5 To ensure that the liquid at the bottom of the liquid storage chamber 211 can flow into the atomizing host 1 along the liquid guide pin 14, the sealing cover 22 of this embodiment is provided with at least one first notch 224 on a portion of the outer wall inside the liquid storage chamber 211. In addition, at least one second notch 142 is provided on the outer wall of the end of the liquid guide pin 14 near the slider 25. Moreover, both the first notch 224 and the second notch 142 are connected to the liquid outlet channel 223. In fact, when the liquid storage shell 21 is in the second and third positions, the liquid storage chamber 211, the first notch 224, the liquid outlet channel 223, the second notch 142 and the liquid guide hole 141 are connected in sequence, so that the liquid in the liquid storage chamber 211 can flow into the atomizing host 1 along the liquid guide pin 14.

[0046] Please refer to the following: Figure 4 and Figure 5The sealing cap 22 specifically includes a sealing shell 225 and a sealing soft rubber 226. The sealing soft rubber 226 has a ring-shaped structure. The sealing soft rubber 226 is sleeved on the sealing shell 225 and fixedly connected to the sealing shell 225. The sealing soft rubber 226 is interference-fitted with the liquid storage chamber 211 to seal the opening of the liquid storage chamber 211. However, the sealing soft rubber 226 can move relative to the liquid storage shell 21 along the straight line of the first direction Z. The sealing shell 225 has the aforementioned first protrusion 222 protruding at one end facing away from the sealing soft rubber 226. In fact, the liquid outlet channel 223 and the first notch 224 are both provided on this sealing shell 225. The aforementioned slider 25 is actually slidably connected to this sealing shell 225 along the straight line of the first direction Z. The aforementioned elastic element 24 is actually provided between the slider 25 and this sealing shell 225.

[0047] Please see Figures 1 to 5 The atomizing host 1 specifically includes an atomizing shell 11, an atomizing core 12, and a battery 13.
