Description

Technical Field

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

[0002] An electronic atomizing device is an electronic device that can atomize liquid vapor-forming substances such as e-liquid or medicinal liquid stored in it into vapor through electric heating. An electronic atomizing device typically includes an atomizing core for generating vapor, a mouthpiece for the user to inhale, and a control chip for controlling the working state of the atomizing core.

[0003] In related technologies, electronic atomizing devices typically use an airflow switch to trigger the atomizer coil to produce a vapor. Specifically, when a user bites down on the mouthpiece and inhales, an airflow is generated inside the electronic atomizing device. This airflow triggers the airflow switch to output a suction signal to the control chip, indicating that the user is inhaling. The control chip responds to this suction signal by energizing the atomizer coil, thereby producing the a vapor for the user to inhale. However, this type of electronic atomizing device that uses an airflow switch to trigger the atomizer coil generally suffers from the following problems:

[0004] Because the airflow switch activates slower than the user's inhalation action, the atomizer coil's activation time is slower than the airflow formation time. This results in the atomized vapor containing too much cold air, thus reducing the user's inhalation experience. Utility Model Content

[0019] In some embodiments, the liquid storage cup includes a top cover, a bottom cover, an air duct having at least a portion of the airflow channel, and a hollow, through-hole cup body.

[0030] Compared with the prior art, this application has at least the following beneficial effects:

[0031] In the technical solution provided in this application embodiment, by setting a button switch and a capacitive touch sensing chip for detecting the human body's touch action on the mouthpiece, and configuring the controller to control the atomizing core to operate when the button switch is pressed by an external force and / or the mouthpiece is touched by a human body, this setting, compared with the traditional technical solution that uses an airflow switch, which can only trigger the atomizing core to operate by inhalation, on the one hand, in actual operation, the user can choose to trigger the atomizing core to operate by pressing the button switch, or by holding the mouthpiece in their lips, or by pressing the button switch and holding the mouthpiece in their lips at the same time, thus making the way to start the electronic atomizing device more diverse and improving the user's flexibility in using the electronic atomizing device; on the other hand, because the user uses electronic atomizing... During the inhalation process, users habitually hold the electronic atomizer's casing first, then put their lips on the mouthpiece, and finally inhale. Therefore, regardless of which of the three activation methods the user chooses to power on the atomizer core, the user's pressing of the button switch and touching of the mouthpiece will precede the user's inhalation action at the mouthpiece. This results in the atomizer core powering on earlier than the time it takes for the suction airflow to form in the airflow channel. As a result, the heat generated by the atomizer core powering on can heat the air around the atomizer core into hot air before the suction airflow forms. When the suction airflow forms, the vapor produced by the atomizer core can mix with the hot air around the atomizer core and then flow out of the mouthpiece into the user's mouth along with the suction airflow. This ensures that the vapor inhaled by the user does not contain too much cold air, thereby improving the user's inhalation experience. Attached Figure Description

[0059] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, top, bottom, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0063] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0064] Furthermore, if the terms "and / or," "and / or," or "and / or" appear throughout the text, their meaning includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Additionally, the specification of this application describes numerous technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined according to actual needs to constitute various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, feature A+B+C is disclosed in one example, and feature A+B+D+E is disclosed in another example. Features C and D are equivalent technical means that serve the same purpose. Technically, only one of them needs to be used, and it is impossible to use them simultaneously. Feature E can be combined with feature C technically. Therefore, the solution A+B+C+D should not be considered as having been recorded because it is technically infeasible, while the solution A+B+C+E should be considered as having been recorded.

[0065] Please refer to Figure 1-9One embodiment of this application provides an electronic atomizing device, which includes a housing 1, a mouthpiece 2, a capacitive touch sensor chip 51, a push-button switch 6, and an atomizing core 3, a battery 4, and a controller 7 disposed within the housing 1, wherein:

[0066] The housing 1 has an airflow channel 931 and a storage cavity 90 for storing liquid vapor-forming substances. In specific implementation, the housing 1 can be an integral structure or a split structure assembled from different housing 1 structures in a detachable or non-detachable manner. The specific structural form of the housing 1 can be determined according to actual use needs, and this embodiment does not impose specific restrictions on it.

[0067] The nozzle 2 is at least partially exposed on the housing 1, and the interior of the nozzle 2 is provided with a suction channel 20 that communicates with the airflow channel 931.

[0068] The atomizing core 3 is connected to the storage chamber 90 so that the atomizing core 3 can draw liquid vapor-forming material from the storage chamber 90 through capillary action, heat and atomize it to produce vapor. Moreover, at least a portion of the atomizing core 3 is located on the airflow path of the airflow channel 931 so that the vapor generated by the atomizing core 3 when it is powered on can be carried away by the suction airflow formed in the airflow channel 931 and discharged to the mouthpiece 2 for the user to inhale.

[0069] A capacitive touch sensor chip 51 is disposed inside the housing 1 or at the nozzle 2. The capacitive touch sensor chip 51 is used to output a touch signal when it detects human body (such as fingers, lips, etc.) touching the nozzle 2. The touch signal can be a high-level signal. It should be noted that in specific implementations, the capacitive touch sensor chip 51 can be of the model SGRT362, HTS1588, DL601H, BL7021, etc., as long as it meets the usage requirements. This embodiment does not impose specific restrictions on the specific model of the capacitive touch sensor chip 51. It can be understood that the capacitive touch sensor chip 51 can detect the human body's touch action on the nozzle 2 by detecting the capacitance change caused when the human body touches the nozzle 2.

[0070] The push-button switch 6 is at least partially exposed on the housing 1. The push-button switch 6 is used to output an open signal when pressed by an external force. It should be noted that in specific implementation, the push-button switch 6 can output an open signal by pressing it for a long time (e.g., for more than 1 second) or by pressing it for a short time (e.g., for less than 0.5 seconds). The open signal can be a high-level signal.

[0071] The controller 7 is electrically connected to the atomizer core 3, the battery 4, the capacitive touch sensor chip 51, and the push-button switch 6 respectively. The controller 7 is configured to control the atomizer core 3 to power on when it receives a touch signal and / or an open signal; that is, the controller 7 is configured to control the atomizer core 3 to power on when it receives any one or both of the touch signal and the open signal.

[0072] In this embodiment, it should be noted that, in specific implementation, the atomizing core 3 can be an integral structure made of porous conductive material (such as foam metal material, porous conductive ceramic material), or it can be a separate structure composed of an electric heating element 31 and a liquid conductor 32 made of different materials, as long as it meets the usage requirements. This embodiment does not impose specific restrictions on the specific structural form of the atomizing core 3. Specifically, when the atomizing core 3 is a separate structure, it includes an electric heating element 31 made of electric heating material (such as metal material) and a liquid conductor 32 made of porous material (such as fiber cotton, sponge, porous ceramic, etc.). The electric heating element 31 is in contact with the liquid conductor 32 and can be electrically connected to the controller 7 through electrode leads, etc. The liquid conductor 32 is connected to the storage cavity 90, so that the liquid conductor 32 can absorb liquid vapor-forming material from the storage cavity 90 through capillary action and transfer it to the electric heating element 31 for heating and atomization. The electric heating element 31 is at least partially located in the airflow. In the airflow path of channel 931, when the user's finger presses the button switch 6 and / or the user's lips touch the mouthpiece 2, the controller 7 connects the electric heating element 31 to the battery 4, so that the electric heating element 31 is energized and heats up. The heat generated by the electric heating element 31 can heat the air around the electric heating element 31 into hot air, and can atomize the liquid vapor-forming substance in contact with the electric heating element 31 into vapor. After the vapor mixes with the hot air, it can be carried away by the suction airflow formed in the airflow channel 931 and discharged to the mouthpiece 2 for the user to inhale.

[0073] In the technical solution provided in this embodiment, by setting a button switch 6 and a capacitive touch sensing chip 51 for detecting the human body's touch action on the mouthpiece 2, and configuring the controller 7 to control the atomizing core 3 to work when the button switch 6 is pressed by an external force and / or the mouthpiece 2 is touched by a human body, this setting, compared with the traditional technical solution that uses an airflow switch and can only trigger the atomizing core 3 to work by inhalation, on the one hand, in actual operation, the user can choose to press the button switch 6 to trigger the atomizing core 3 to work, or choose to put the mouthpiece 2 in their mouth to trigger the atomizing core 3 to work, or choose to press the button switch 6 and put the mouthpiece 2 in their mouth at the same time to trigger the atomizing core 3 to work, thus making the way to start the electronic atomizing device more diverse and improving the user's flexibility in using the electronic atomizing device; on the other hand, since the user is accustomed to holding the shell of the electronic atomizing device first when using it for inhalation. Take the atomizer 1, then put the mouthpiece 2 in your mouth with your lips, and finally inhale. Therefore, regardless of whether the user chooses to press the button switch 6 to trigger the atomizer 3 to work, or chooses to put the mouthpiece 2 in their mouth while pressing the button switch 6, the user's pressing action on the button switch 6 and touching action on the mouthpiece 2 will be earlier than the user's inhalation action at the mouthpiece 2. Therefore, the atomizer 3 will be powered on earlier than the time when the suction airflow is formed in the airflow channel 931. In this way, the heat generated by the atomizer 3 to work can heat the air around the atomizer 3 into hot air before the suction airflow is formed. Then, when the suction airflow is formed, the vapor produced by the atomizer 3 can mix with the hot air around the atomizer 3 and then flow out from the mouthpiece 2 into the user's mouth with the suction airflow. This ensures that the vapor inhaled by the user will not contain too much cold air, thereby improving the user's inhalation experience.

[0074] It should be noted that, in practical implementation, two control modes can be set for controller 7: the first is the default mode, in which controller 7 is configured to power on the atomizer core 3 when it receives either a touch signal or an activation signal; the second is the anti-accidental touch mode, in which controller 7 is configured to power on the atomizer core 3 only when it receives either a touch signal or an activation signal. Compared to the default mode, this reduces the risk of accidental activation and self-starting of the electronic atomizer during transportation, carrying, or use. The default mode and the anti-accidental touch mode can be switched between each other. For example, the default mode and the anti-accidental touch mode can be switched by pressing the button switch 6 repeatedly (e.g., pressing the button switch 6 3 times in 1 second). Specifically, in the default mode, when the controller 7 receives multiple (e.g., 3) opening signals within a preset time (e.g., 1 second), the controller 7 switches the current control mode from the default mode to the anti-accidental touch mode; while in the anti-accidental touch mode, when the controller 7 receives multiple (e.g., 3) opening signals within a preset time (e.g., 1 second), the controller 7 switches the current control mode from the anti-accidental touch mode back to the default mode.

[0075] In this embodiment, it should also be noted that when the controller 7 is configured to power on the atomizing core 3 only when it receives either a touch signal or an activation signal, in some specific usage scenarios, the controller 7 will only power on the atomizing core 3 when the user's finger presses the button switch 6 and the user's lips touch the mouthpiece 2. In other specific usage scenarios, before using the electronic atomizing device for inhalation, the capacitive touch sensing chip 51 is in a dormant state where it cannot detect human touch. After the user presses the button switch 6 briefly at least once, the controller 7 can activate the capacitive touch sensing chip 51 in response to the activation signal provided by the button switch 6 (specifically, the controller 7 can activate the capacitive touch sensing chip 51 by sending an activation signal to the capacitive touch sensing chip 51), so that the capacitive touch sensing chip 51 changes from a dormant state to a working state where it can detect human touch. Subsequently, when the user's lips are in the mouthpiece 2 for inhalation, the controller 7 can power on the atomizing core 3 in response to the touch signal sent by the capacitive touch sensing chip 51.

[0076] Furthermore, considering that the nozzle 2 is usually small in size, it is difficult to install the capacitive touch sensing chip 51 inside or on the surface of the nozzle 2 in actual operation. Therefore, in some specific application scenarios, the capacitive touch sensing chip 51 is usually placed in the housing 1 with a larger installation space. In this case, the capacitive touch sensing chip 51 can detect the human body's touch action on the nozzle 2 and output a touch signal to indicate that the human body has touched the nozzle 2 through the following structural design:

[0077] Specifically, please refer to Figure 7-8 In some optional embodiments of this application, the electronic atomizing device further includes a conductor 53, which may be in the form of a metal sheet, a metal needle, or the like. The conductor 53 may be electrically connected to the capacitive touch sensing chip 51 via wires or the like. The nozzle 2 is made of insulating plastic and is connected to the top of the housing 1. The capacitive touch sensing chip 51 is disposed inside the housing 1, and the conductor 53 is disposed inside the nozzle 2 and is in contact with the nozzle 2.

[0078] In this embodiment, based on the above structural design, since the conductor 53 is a conductor, and the human body can also be considered a conductor, when the human body touches the nozzle 2, it is equivalent to connecting a human body capacitor in parallel at the conductor 53. Therefore, the capacitance at the conductor 53 will change, allowing the capacitive touch sensing chip 51 to output a touch signal to the controller 7 by sensing the capacitance change caused by the human body touching the nozzle 2. In specific implementation, to enable the capacitive touch sensing chip 51 to detect the human body's touch action on the nozzle 2 more accurately and stably, the capacitive touch sensing chip 51 should be placed as close as possible to the nozzle 2.

[0079] Furthermore, in some alternative embodiments of this application, when the capacitive touch sensing chip 51 is disposed within the housing 1, the capacitive touch sensing chip 51 can also be configured to detect human touch on the nozzle 2 and output a touch signal indicating that the human has touched the nozzle 2 through the following structural design:

[0080] Specifically, please refer to Figure 5-6 The electronic atomizing device also includes a flexible wire 52, which can be a flexible flat cable or an ordinary metal wire. The mouthpiece 2 is made of conductive plastic and is insulatedly connected to the top of the housing 1. The capacitive touch sensing chip 51 is disposed inside the housing 1. The first end of the flexible wire 52 is pressed into contact with the mouthpiece 2, and the second end of the flexible wire 52 can be electrically connected to the capacitive touch sensing chip 51 by means of welding or other methods.

[0081] In this embodiment, it should be noted that the insulating connection between the nozzle 2 and the housing 1 can be achieved in various ways. For example, in some optional embodiments, the part connecting the housing 1 and the nozzle 2 can be made of an insulating material (such as insulating plastic) to achieve an insulating connection between the nozzle 2 and the housing 1. Alternatively, in other optional embodiments, when the part connecting the housing 1 and the nozzle 2 is made of a conductive material (such as metal), an insulating element made of an insulating material (such as silicone) can be provided between the nozzle 2 and the housing 1 to achieve an insulating connection between the nozzle 2 and the housing 1. Furthermore, in specific implementations, the nozzle 2 can be formed by injection molding of a conductive plastic resulting from a mixture of insulating plastic (such as polycarbonate) and conductive powder (such as metal powder or carbon powder).

[0082] In this embodiment, it should also be noted that, in order to enable the capacitive touch sensing chip 51 to detect the human body's touch action on the nozzle 2 more accurately and stably, the capacitive touch sensing chip 51 should be placed as close as possible to the nozzle 2.

[0083] In this embodiment, based on the above structural design, since the suction nozzle 2 is a conductor, and the human body can also be considered a conductor, when the human body touches the suction nozzle 2, it is equivalent to connecting a human body capacitor in parallel at the suction nozzle 2. Therefore, the capacitance at the suction nozzle 2 will change, so that the capacitive touch sensing chip 51 can output a touch signal to the controller 7 by sensing the capacitance change caused by the human body touching the suction nozzle 2. The flexible wire 52 facilitates the electrical connection between the suction nozzle 2 and the capacitive touch sensing chip 51. Moreover, the electrical connection between the flexible wire 52 and the suction nozzle 2 is achieved by squeezing contact, which is not only highly reliable but also easy to operate. In addition, compared with the touch detection scheme that sets the conductor 53 inside the suction nozzle 2 made of insulating plastic, this embodiment uses a conductive suction nozzle 2 instead of setting the conductor 53 inside the insulating suction nozzle 2, which helps to save on the assembly cost of the parts (because the step of assembling the conductor 53 inside the suction nozzle 2 is eliminated).

[0084] Furthermore, in some optional embodiments of this application, the first end of the flexible wire 52 and the suction nozzle 2 can achieve a compression contact through the following structural design:

[0085] Specifically, please refer to the following: Figure 1 , Figure 3 , Figure 5-6 , Figure 11 as well as Figure 15The electronic atomizing device also includes a liquid reservoir 9 disposed within the housing 1. The liquid reservoir 9 has a storage chamber 90 and at least a partial airflow channel 931 inside. The atomizing core 3 is installed inside the liquid reservoir 9. The top of the housing 1 has an installation port 120. The part of the housing 1 with the installation port 120 is made of insulating material (optionally, the entire housing 1 can be made of insulating material). The mouthpiece 2 can be fixed to the installation port 120 by means of snap-fit ​​connection, etc. The top of the liquid reservoir 9 has a groove 913 facing the installation port 120. The inner wall of the groove 913 is made of flexible sealing material (such as silicone, rubber or silicone rubber). The lower end of the mouthpiece 2 is inserted into the groove 913. The first end of the flexible wire 52 is clamped between the inner peripheral wall of the groove 913 and the outer peripheral wall of the mouthpiece 2.

[0086] In this embodiment, based on the above structural design, when electrically connecting the first end of the flexible wire 52 to the nozzle 2, it is only necessary to place the first end of the flexible wire 52 in the groove 913 of the liquid storage cup 9, and then pass the lower end of the nozzle 2 through the mounting port 120 of the housing 1 and insert it into the groove 913 for engagement. This will tightly clamp the first end of the flexible wire 52 between the inner peripheral wall of the groove 913 and the outer peripheral wall of the lower end of the nozzle 2 (since the inner wall of the groove 913 is made of flexible sealing material and has a certain elasticity, while the nozzle 2 is made of conductive plastic and has a certain hardness, the first end of the flexible wire 52 can be tightly clamped between the inner peripheral wall of the groove 913 and the outer peripheral wall of the lower end of the nozzle 2), thereby enabling reliable electrical contact between the flexible wire 52 and the nozzle 2.

[0087] Furthermore, in some optional embodiments of this application, the suction nozzle 2 can be fixed to the mounting port 120 of the housing 1 in the following manner:

[0088] Specifically, please refer to the following: Figure 3 as well as Figure 11-12 The inner wall of the mounting port 120 has a stepped portion 123, and the outer wall of the suction nozzle 2 has a shoulder portion 21 and multiple limiting buckles 22 located below the shoulder portion 21. The shoulder portion 21 matches the mounting port 120 and covers the stepped portion 123. The multiple limiting buckles 22 are arranged opposite to the side of the stepped portion 123 facing away from the shoulder portion 21 (i.e., the lower side of the stepped portion 123). (At this time, the multiple limiting buckles 22 and the lower surface of the stepped portion 123 can contact each other or there can be a gap) to prevent the suction nozzle 2 from detaching from the mounting port 120 in the direction away from the liquid storage cup 9 (i.e., upward). This arrangement makes it easy to quickly and neatly fix the suction nozzle 2 to the mounting port 120 of the housing 1. Specifically, when assembling the suction nozzle 2, simply insert the lower end of the suction nozzle 2 into the mounting port 120 and apply force to press the multiple limiting buckles 22 into the lower side of the stepped portion 123, which is relatively convenient.

[0089] Furthermore, in some optional embodiments of this application, the specific structural composition of the liquid storage cup 9 and the communication method between the storage cavity 90 and the atomizing core 3 can be achieved through the following structural design:

[0090] Specifically, please refer to Figure 3 as well as Figure 15-16 The liquid storage cup 9 includes a top cover 91, a bottom cover 92, an airway tube 93 having at least a partial airflow channel 931, and a hollow, through-hole cup body 94. Both the top cover 91 and the bottom cover 92 are made of flexible sealing material, and the cup body 94 can be made of plastic. The airway tube 93 can be an integral structure or an assembled structure. When the airway tube 93 is an integral structure, its material can be stainless steel. The top cover 91 is sealed to the upper end of the cup body 94, and the bottom cover 92 is sealed to the lower end of the cup body 94. The top cover 91 has a first mounting through hole 911 and a groove 913 coaxially arranged with the first mounting through hole 911. The bottom cover 92 has a second mounting through hole 921. The first end of the airway tube 93 is sealed to the first mounting through hole 921. Inside the through hole 911, the second end of the air passage tube 93 is sealed and fitted inside the second mounting through hole 921. The top cover 91, bottom cover 92, air passage tube 93, and cup body 94 together define the storage cavity 90. The side wall of the air passage tube 93 is provided with a liquid passage hole 932 that communicates with the storage cavity 90. The atomizing core 3 is at least partially located inside the air passage tube 93 and is configured to cover the liquid passage hole 932 (that is, the atomizing core 3 can communicate with the storage cavity 90 through the liquid passage hole 932). For example, the atomizing core 3 includes an electric heating element 31 and a liquid guide 32 made of porous material. The liquid guide 32 is at least partially located inside the air passage tube 93. The liquid guide 32 surrounds and covers the liquid passage hole 932. The electric heating element 31 is in contact with the inner wall of the liquid guide 32 and is electrically connected to the controller 7.

[0091] Further, please refer to Figure 3 In some optional embodiments of this application, a storage liquid 95 made of porous material (such as fiber cotton, sponge, etc.) is disposed in the storage cavity 90, and the storage liquid 95 covers the liquid passage hole 932. In this embodiment, the storage liquid 95 can adsorb the liquid vapor-forming substance in the storage cavity 90, and can transfer the adsorbed liquid vapor-forming substance to the guiding liquid 32 of the atomizing core 3 through the liquid passage hole 932. Compared with not disposing of the storage liquid 95 in the storage cavity 90, the presence of the storage liquid 95 can slow down the speed at which the liquid vapor-forming substance is guided to the atomizing core 3, so that the liquid vapor-forming substance can be guided to the atomizing core 3 at a more appropriate speed. This helps to reduce the risk of liquid vapor-forming substance seeping out of the atomizing core 3 due to the liquid vapor-forming substance in the storage cavity 90 being guided to the atomizing core 3 too quickly, thereby causing leakage of the electronic atomizing device.

[0092] Furthermore, considering that when the electronic atomizing device is in a negative pressure environment with an air pressure lower than standard atmospheric pressure (e.g., in a high-altitude environment during air transport by airplane), on the one hand, the liquid vapor-forming substance adsorbed by the storage liquid 95 will expand in volume and overflow from the storage liquid 95 (this is because, during the production of the electronic atomizing device, the liquid vapor-forming substance in the storage liquid 95 is injected under standard atmospheric pressure ground conditions, and air will be dissolved in the liquid vapor-forming substance; when the external air pressure decreases, the solubility of air in the liquid vapor-forming substance decreases). The pressure will decrease, causing the liquid vapor-forming material to precipitate as bubbles from the liquid vapor-forming material. These bubbles will occupy the limited internal space of the oil-retaining cotton, thus compressing the liquid vapor-forming material and causing it to expand in volume. On the other hand, the air pressure inside the storage chamber 90 will increase (because some bubbles in the storage liquid 95 precipitate from the storage liquid 95, increasing the air pressure inside the storage chamber 90). These two factors cause the liquid vapor-forming material overflowing from the storage liquid 95 to be guided more quickly towards the atomizing core 3, leading to leakage in the electronic atomizing device. Based on the above considerations, to reduce the risk of leakage in the electronic atomizing device under negative pressure, the following optimized structural design can be implemented:

[0093] Specifically, please refer to the following: Figure 3 and Figure 15 In some optional embodiments of this application, the end of the liquid storage 95 away from the top cover 91 is in contact with the bottom cover 92. There is a gap (the size of the gap can be 2mm to 10mm) between the side surface of the top cover 91 facing the bottom cover 92 and the side surface of the liquid storage 95 facing the top cover 91, forming an exhaust space 901. The top cover 91 is also provided with an exhaust hole 912 spaced apart from the first mounting through hole 911. The exhaust hole 912 is connected to the exhaust space 901 and the airflow channel 931 respectively (exemplarily, the bottom wall of the groove 913 is provided with an exhaust groove 915 connected to the exhaust hole 912 and the first mounting through hole 911 respectively. The lower end of the exhaust hole 912 is connected to the exhaust space 901, and the upper end of the exhaust hole 912 is connected to the airflow channel 931 through the exhaust groove 915). With this configuration, when the electronic atomizing device is in a negative pressure environment, firstly, the liquid vapor-forming material overflowing from the storage liquid 95 can be temporarily stored in the exhaust space 901; secondly, after the bubbles precipitated from the storage liquid 95 turn into air, they can be discharged into the airflow channel 931 through the exhaust port 912, avoiding an increase in air pressure in the storage chamber 90; thirdly, after the bubbles precipitate from the storage liquid 95, excess storage space is generated inside the storage liquid 95, allowing the storage liquid 95 to reabsorb the liquid vapor-forming material temporarily stored in the exhaust space 901 back into its interior. These three aspects ensure that the liquid vapor-forming material does not accelerate its guidance to the atomizing core 3, thereby effectively reducing the risk of leakage in the electronic atomizing device under negative pressure.

[0094] Furthermore, considering that during the transportation of the electronic atomizing device, the liquid reservoir 95 may shift along the height of the cup 94 due to factors such as bumps during transit, which may result in the liquid reservoir 95 failing to completely cover the liquid passage 932 or even failing to cover it at all. This could lead to a problem of dry burning due to insufficient liquid in the atomizer coil 3 during subsequent vaping use (when the atomizer coil 3 experiences dry burning due to insufficient liquid, it not only affects the user's vaping experience but may also damage the atomizer coil 3). Therefore, to avoid the problem of dry burning due to insufficient liquid in the atomizer coil 3 during subsequent vaping use, please refer to... Figure 3 In some optional embodiments of this application, a blocking protrusion 914 is provided on the side of the top cover 91 facing the bottom cover 92, and the blocking protrusion 914 abuts against the surface of the liquid storage 95 facing the blocking protrusion 914. This arrangement serves two purposes: firstly, during the transport of the electronic atomizing device, the blocking protrusion 914 prevents the liquid storage 95 from flowing upwards along the height direction of the cup body 94 and failing to completely cover the liquid passage 932, thereby effectively reducing the risk of dry burning of the atomizing core 3 due to lack of liquid during subsequent inhalation; secondly, the blocking protrusion 914 ensures the formation of the exhaust space 901, thus preventing leakage of the electronic atomizing device in a negative pressure environment.

[0095] Further, please refer to Figure 5-11 In some optional embodiments of this application, the electronic atomizing device further includes a first circuit board 81, and the controller 7 includes a second circuit board 72, a microcontroller 71, and a switching transistor 73. The first circuit board 81 and the second circuit board 72 are spaced apart within the housing 1. The capacitive touch sensing chip 51 is fixed on the first circuit board 81. In some application scenarios, the second end of the flexible wire 52 can be fixedly connected to the first circuit board 81 by welding, plugging (at this time, the first circuit board 81 can also be provided with a connector for plugging in the flexible flat cable), etc., thereby realizing the electrical connection between the second end of the flexible wire 52 and the capacitive touch sensing chip 51. The microcontroller 71 and the switching transistor 73 are both fixed on the second circuit board 72. The microcontroller 71 is electrically connected to the switching transistor 73, the atomizing core 3, the battery 4, the capacitive touch sensing chip 51, and the push-button switch 6, respectively.

[0096] The microcontroller 71 is configured to turn on the switch 73 when it receives a touch signal and / or an open signal, thereby connecting the atomizer core 3 to the battery 4 and powering on the atomizer core 3. When it does not receive a touch signal and / or an open signal, it controls the switch 73 to turn off, thereby disconnecting the atomizer core 3 from the battery 4 and stopping the atomizer core 3 from working. Specifically, in the default mode, if the user neither presses the button switch 6 nor touches the mouthpiece 2, the controller 7 will not power on the atomizer core 3 because it has not received either the open signal or the touch signal. In the anti-accidental touch mode, if the user neither presses the button switch 6 nor touches the mouthpiece 2, or only presses the button switch 6 but does not touch the mouthpiece 2, or only touches the mouthpiece 2 but does not press the button switch 6, the controller 7 will not power on the atomizer core 3 because it has not received either the open signal or the touch signal.

[0097] In this embodiment, it should be noted that, in specific implementations, the microcontroller 71 can be of the model CSU32M10, AT32F421C8T7, etc., as long as it meets the usage requirements. This embodiment does not impose specific restrictions on the specific model of the microcontroller 71. Furthermore, in specific implementations, the switching transistor 73 can be a diode, transistor, metal-oxide-semiconductor field-effect transistor (i.e., MOSFET), etc., as long as it meets the usage requirements. This embodiment does not impose specific restrictions on the type of switching transistor 73.

[0098] In this embodiment, it is understood that the various components on the first circuit board 81 can be electrically connected through the circuit traces on the first circuit board 81. Similarly, the various components on the second circuit board 72 can be electrically connected through the circuit traces on the second circuit board 72. Furthermore, the first circuit board 81 and the second circuit board 72 can be electrically connected via wires.

[0099] In this embodiment, based on the above structural design, firstly, the first circuit board 81 can serve as a mounting carrier for the capacitive touch sensing chip 51, thereby facilitating the flexible installation of the capacitive touch sensing chip 51 in the required position; secondly, by integrating the microcontroller 71 and the switching transistor 73 onto the second circuit board 72, the entire controller 7 can be easily installed in the required position.

[0100] Further, please refer to Figure 3 , Figure 9 as well as Figure 11In some optional embodiments of this application, the electronic atomizing device further includes a display component 8 having a first circuit board 81. The display component 8 is installed inside the housing 1 and electrically connected to the microcontroller 71. The portion of the housing 1 that covers the display component 8 is made of a light-transmitting material (such as glass, acrylic, polycarbonate, etc.). The push-button switch 6 includes a switch body 62 and a resilient hand button 61. The switch body 62 is fixed on the first circuit board 81 and electrically connected to the microcontroller 71. The resilient hand button 61 is at least partially exposed on the housing 1 and is disposed corresponding to the switch body 62. When the resilient hand button 61 is pressed by an external force, the resilient hand button 61 touches the switch body 62, thereby causing the switch body 62 to output an open signal to the microcontroller 71. When the external force applied to the resilient hand button 61 is removed, the resilient hand button 61 returns to its natural state of not touching the switch body 62. At this time, the switch body 62 does not output an open signal to the microcontroller 71.

[0101] In this embodiment, based on the above structural design, by adding a display component 8 with a first circuit board 81, not only can the electronic atomizing device be given a display function (specifically, the display component 8 can display preset animation patterns, the remaining power of the battery 4, the working power of the atomizing core 3, and other information), but also, since the display component 8 has its own circuit board, the capacitive touch sensing chip 51 and the switch body 62 of the button switch 6 can share the same circuit board with the display component 8, without the need for an additional separate circuit board to support the capacitive touch sensing chip 51 or the switch body 62. This helps to reduce the component cost of the electronic atomizing device.

[0102] In this embodiment, it should be noted that, in specific implementations, the display component 8 can be an LED digital tube, an LCD screen, a TFT color screen, a flexible display component 8, etc., which can be determined according to actual usage requirements. This embodiment does not impose specific restrictions on the specific type of the display component 8. Furthermore, in some specific application scenarios, the switch body 62 can be a tactile switch.

[0103] Furthermore, in some optional embodiments of this application, the specific structural form of the elastic hand button 61 can be as follows:

[0104] Please refer to the reference. Figure 3-4 , Figure 11 as well as Figure 13-14The elastic hand button 61 is made of elastic plastic (such as polycarbonate, polyethylene, polypropylene, ABS plastic, etc.). The housing 1 has a mounting hole 124 in the part covering the display component 8. The mounting hole 124 is set corresponding to the switch body 62. The elastic hand button 61 includes a pressing part 611, an elastic arm 612 and a protrusion 613 connected to each other. The pressing part 611 passes through the mounting hole 124. The first end of the elastic arm 612 is fixed in the housing 1. The second end of the elastic arm 612 is connected to the end of the pressing part 611 near the switch body 62. The protrusion 613 is set on the side of the pressing part 611 facing the switch body 62 and is opposite to the switch body 62. When the pressing part 611 is pressed by an external force, the elastic arm 612 undergoes elastic deformation and causes the protrusion 613 to move in the direction close to the switch body 62 to press the switch body 62.

[0105] In this embodiment, based on the above structural design, compared with the traditional push button switch 6 which adopts a hand-press structure design of "using the button cap to press the switch body 62 and using the elastic element to reset the button cap", the elastic hand-press 61 provided in this embodiment is an integrated structure, and has the functions of being pressable and automatically springing back (that is, the elastic hand-press 61 provided in this embodiment can simultaneously play the roles of a traditional button cap and an elastic element). Therefore, it is beneficial to improve the assembly efficiency of the electronic atomization device (because the step of assembling the elastic element is eliminated) and the cost of parts (because the elastic element is eliminated).

[0106] Further, please refer to Figure 1 as well as Figure 3-4 In some optional embodiments of this application, the side surface of the pressing part 611 facing away from the switch body 62 is flush with the outer surface of the housing 1. This arrangement, compared to making the pressing part 611 protrude from the outer surface of the housing 1, not only improves the aesthetic appearance of the electronic atomizing device, but also reduces the risk of accidental activation of the button switch 6 during transportation, carrying, or use of the electronic atomizing device.

[0107] Further, please refer to Figure 3-4 , Figure 10-11 as well as Figure 13-14In some optional embodiments of this application, the housing 1 includes an inner housing 11 and an outer housing 12 with a mounting hole 124. The display component 8 is disposed on the outside of the inner housing 11. The outer housing 12 encloses the inner housing 11 and covers the display component 8. The atomizing core 3, the battery 4, and the controller 7 are all disposed inside the outer housing 12. The mouthpiece 2 is disposed on the top of the outer housing 12. A connecting post 125 is provided on the inner wall of the outer housing 12. A connecting hole 610 is opened at the first end of the elastic arm 612. The connecting post 125 and the connecting hole 610 are interference-fitted. More specifically, the outer housing 12 includes a first housing portion 121 with a mounting opening 120 and a second housing portion 122 made of a light-transmitting material. The first housing portion 121 and the second housing portion 122 can be spliced ​​together by snap-fitting to form a complete outer housing 12. The mounting hole 124 and the connecting post 125 are both disposed on the second housing portion 122. The atomizing core 3, the battery 4, and the controller 7 are all disposed inside the inner housing 11.

[0108] In this embodiment, based on the above structural design, by providing a connecting post 125 on the inner wall of the outer shell 12 and providing a connecting hole 610 that matches the connecting post 125 at the first end of the elastic arm 612, the installation and fixing of the elastic hand button 61 can be quickly completed by simply engaging the connecting post 125 with the connecting hole 610 when assembling the elastic hand button 61, making the operation more convenient.

[0109] Further, please refer to Figure 1-4 In some optional embodiments of this application, the housing 1 has a top surface 101 and a bottom surface 102 that are opposite to each other along its height direction. The housing 1 also has a front side surface 103, a right side surface 104, a rear side surface 105, and a left side surface 106 that are smoothly connected sequentially between the top surface 101 and the bottom surface 102 along its circumference. The front side surface 103 and the rear side surface 105 are opposite to each other, and the left side surface 106 and the right side surface 104 are opposite to each other. The width of the rear side 105 is greater than that of the left side 106 and the right side 104. The suction nozzle 2 is connected to the top surface 101. The suction nozzle 2 is positioned closer to the left side 106 than the right side 104. The mounting hole 124 is located on the right side 104. Along the height direction of the housing 1, the vertical distance between the axis of the mounting hole 124 and the top surface 101 is 12-22 mm. The vertical distance between the bottom surface 102 and the top surface 101 is 68-100 mm. For example, Figure 4 As shown, assuming the vertical distance between the axis of the mounting hole 124 and the top surface 101 is H, then 12mm≤H≤22mm.

[0110] In this embodiment, it should be noted that the top surface 101, bottom surface 102, front side surface 103, right side surface 104, rear side surface 105, and left side surface 106 can be planes, curved surfaces, or formed by connecting planes and curved surfaces. They can be determined according to actual usage needs, and this embodiment does not impose specific limitations on them.

[0111] In this embodiment, based on the above structural design, the position layout of the pressing part 611 is more ergonomic, which makes it easier for the user to press the button switch 6 more comfortably when holding the electronic atomizing device for inhalation. Specifically, in some usage scenarios where the atomizing core 3 needs to be powered on by pressing the button switch 6, when the user holds the shell 1, the user's index finger can easily and naturally contact the pressing part 611, so that the user can press the button switch 6 more comfortably with the index finger.

[0112] It should be noted that other aspects of the electronic atomizing device disclosed in this application that are not described in detail can be found in the prior art, and will not be repeated here.

[0113] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. All equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
