[0002] Electronic atomizing products are widely equipped with inhalation detection elements.

[0031] In one embodiment, the atomizer further includes a conduit section extending away from the power supply device; the conduit section connects the trigger air passage and the inhalation passage.

[0055] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0056] To enable those skilled in the art to better understand the solutions of this application, 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 them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0057] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0058] Reference Figures 1 to 3 The first aspect of this utility model provides a power supply device 1, including a housing 11, a triggering component 12, and a blocking component 13. The housing 11 is used to install an atomizer 2, and a triggering air passage 111 is provided inside the housing 11. The triggering component 12 is disposed in the triggering air passage 111 and is used to control the on / off state of the electrical connection between the power supply device 1 and the atomizer 2. The blocking component 13 is movably installed on the housing 11 so that the blocking component 13 can move to open or close the triggering air passage 111. Wherein, when the atomizer 2 is installed in the housing 11, the triggering air passage 111 is connected to the inhalation channel 21 of the atomizer 2 so that when the user inhales through the inhalation channel 21, the triggering component 12 can be triggered to realize the electrical connection between the power supply device 1 and the atomizer 2.

[0059] The trigger component 12 may include a detection structure such as an airflow sensor, a micro switch, a membrane switch, or a light sensor. By detecting changes in airflow or light generated when the atomizer 2 is installed on the housing 11, the installation of the atomizer 2 can be detected, thereby realizing the electrical connection between the power supply device 1 and the atomizer 2, which facilitates the user's inhalation.

[0060] The shield 13 is movably disposed on the housing 11 and can be a simple baffle or other structure, allowing the user to manually control the movement of the shield 13, thereby controlling the opening and closing of the trigger air passage 111; the shield 13 may also include a motor, cylinder or other drive structure to realize automatic control of the opening and closing of the trigger air passage 111, and this utility model does not limit this.

[0061] The trigger component 12 is disposed within the trigger air passage 111 of the housing 11. The opening and closing of the trigger air passage 111 can be controlled by a movable shield 13, reducing the probability of the power supply device 1 being triggered when not in use. This improves the sealing of the power supply device 1 without affecting its power supply function, reduces the probability of contamination of the trigger component 12, and extends the service life of the power supply device 1. Furthermore, when the atomizer 2 is installed, the trigger air passage 111 is connected to the inhalation channel 21, allowing the airflow generated during inhalation to directly act on the trigger component 12, thereby automatically controlling the electrical connection between the power supply device 1 and the atomizer 2. This reduces the difficulty of operation for the user and improves the user experience.

[0062] In one embodiment, reference is made to Figure 2 and Figure 3 At least part of the shield 13 is disposed at the opening of the trigger air passage 111. The shield 13 is rotatably connected to the housing 11 so that the shield 13 can be rotated to open or close the trigger air passage 111.

[0063] For example, a through hole can be provided on the blocking member 13. When the blocking member 13 is rotated to a specific position, the through hole communicates with the trigger air passage 111, thereby opening the trigger air passage 111; when the blocking member 13 is rotated to other positions, the through hole and the trigger air passage 111 are misaligned, thereby closing the trigger air passage 111. It is understood that the through hole can also be replaced with a notch or other structures.

[0064] By rotatably connecting the shield 13 to the housing 11 and covering the opening of the trigger air passage 111, the user can control the opening and closing of the trigger air passage 111 by controlling the rotation angle of the shield 13, eliminating the need for alignment and reducing the difficulty of operation. Furthermore, the rotatable shield 13 occupies less space, allowing for a smoother outer surface of the power supply device 1, and its rotation does not interfere with other structures, reducing the probability of damage to the shield 13 or other structures.

[0065] In one embodiment, reference is made to Figures 2 to 4 The housing 11 is used to rotatably mount the atomizer 2 so that the atomizer 2 rotates and drives the shield 13 to rotate.

[0066] Specifically, corresponding snap-fit ​​structures can be provided on the atomizer 2 and the shielding member 13. For example, a groove can be provided on one of the atomizer 2 and the shielding member 13, and a protrusion on the other. When the atomizer 2 is installed on the housing 11, the groove and the protrusion engage, and the rotation of the atomizer 2 can also drive the shielding member 13 to rotate, thereby controlling the opening and closing of the trigger airway 111. It can be understood that the atomizer 2 can also drive the shielding member 13 through friction alone.

[0067] This embodiment of the invention integrates the installation / removal process of the atomizer 2 with the airflow channel opening and closing control by rotating the atomizer 2 onto the housing 11 and linking it with the shielding component 13. This simplifies the user's operation, reduces the difficulty of operation, and improves the user experience. Furthermore, when the atomizer 2 is rotated out to separate from the power supply device 1, the atomizer 2 automatically drives the shielding component 13 to close the trigger airflow channel 111, preventing the user from forgetting to close the trigger airflow channel 111. This reduces the probability of foreign objects entering the trigger airflow channel 111 and contaminating the trigger assembly 12 after the atomizer 2 is disassembled, and improves the sealing performance of the power supply device 1.

[0068] In one embodiment, reference is made to Figures 2 to 4 The power supply device 1 is provided with a threaded connection part 14, which is used to connect with the atomizer 2 by thread; the shielding part 13 is arranged around the threaded connection part 14.

[0069] The power supply device 1 is threadedly connected to the atomizer 2 via a threaded connection part 14. This allows the atomizer 2 to approach the shielding member 13 relatively smoothly during tightening, until the shielding member 13 rotates. This ensures the stability of the connection between the atomizer 2 and the power supply device 1, and also utilizes the friction between the atomizer 2 and the shielding member 13 to effectively drive the shielding member 13 to close or open the trigger airway 111. The shielding member 13 is arranged around the threaded connection part 14, allowing sufficient pressure to be formed between the atomizer 2 and the shielding member 13, enabling the atomizer 2 to drive the shielding member 13 to rotate and ensuring the normal use of the shielding member 13.

[0070] In one embodiment, reference is made to Figures 2 to 4 The shielding member 13 is provided with a limiting protrusion 131, and the housing 11 is provided with a limiting groove 112. At least part of the limiting protrusion 131 is accommodated in the limiting groove 112 to limit the rotation angle of the shielding member 13.

[0071] A limiting protrusion 131 is provided on the shielding member 13, which cooperates with the limiting groove 112 on the housing 11. When the shielding member 13 rotates with the atomizer 2, the contact surface between the limiting protrusion 131 and the limiting groove 112 forms a mechanical stop, thereby limiting the rotation angle of the shielding member 13 within a preset range. The dimensions of the limiting protrusion 131 and the limiting groove 112 can be set to allow the shielding member 13 to have a suitable rotation angle. Preferably, when one end of the limiting protrusion 131 abuts against the limiting groove 112, the air passage 111 is triggered to open; when the other end of the limiting protrusion 131 abuts against the limiting groove 112, the air passage 111 is triggered to close.

[0072] In this embodiment of the invention, the cooperation between the limiting protrusion 131 and the limiting groove 112 ensures that the blocking member 13 can be rotated relatively accurately to the position where the trigger air passage 111 is fully opened or closed. At the same time, the tactile feedback generated when the limiting protrusion 131 contacts the limiting groove 112 can also prompt the user, improving the user experience.

[0073] In one embodiment, reference is made to Figures 2 to 4 The shielding component 13 includes a body 132 and a sealing component 133. The body 132 is movably installed on the housing 11, and a limiting protrusion 131 is provided on the body 132. The hardness of the sealing component 133 is less than that of the body 132. The sealing component 133 is provided on the body 132, and when the atomizer 2 is installed, the sealing component 133 is sandwiched between the body 132 and the atomizer 2 to perform a seal.

[0074] The sealing element 133, with its lower hardness, can be made of materials such as silicone or rubber. This provides greater friction, enabling the atomizer 2 to drive the shielding element 13. Simultaneously, the interference fit between the atomizer 2 and the sealing element 133 achieves a better sealing effect, reducing the probability of internal contamination of the power supply device 1. The body 132, with its higher hardness, provides support. The limiting protrusion 131, located on the body 132, prevents excessive friction between the atomizer 2 and the shielding element 13 from deforming, causing the shielding element 13 to rotate too much, thus interfering with the opening and closing of the trigger airway 111.

[0075] In one optional embodiment, the body 132 and the seal 133 are detachably connected. Specifically, the body 132 may be provided with a snap-fit ​​groove, and the seal 133 may be provided with a snap-fit ​​protrusion corresponding to the snap-fit ​​groove. The snap-fit ​​protrusion and the snap-fit ​​groove are snapped together or press-fitted together, thereby realizing the connection between the body 132 and the seal 133.

[0076] In an optional embodiment, the power supply device 1 further includes a decorative panel that surrounds the shield 13 and at least partially covers the body 132 to protect the body 132 of the shield 13 and the limiting protrusion 131 on the body 132, and to serve a decorative purpose, making the power supply device 1 flatter overall.

[0077] In one embodiment, the rotation angle of the shielding member 13 is greater than or equal to 20° and less than or equal to 22°. If the rotation angle is less than 20°, the rotation angle that the shielding member 13 can rotate is too small, and prolonged friction between the atomizer 2 and the shielding member 13 can easily damage both the atomizer 2 and the shielding member 13. If the rotation angle is greater than 22°, a larger limiting groove 112 needs to be made, which reduces the structural strength of the housing 11 and thus affects the service life of the power supply device 1. Therefore, in this embodiment of the invention, the rotation angle of the shielding member 13 is set to be greater than or equal to 20° and less than or equal to 22°, so that the housing 11 has sufficient structural strength while preventing prolonged friction between the atomizer 2 and the shielding member 13, thus reducing the probability of damage to both.

[0078] In one embodiment, reference is made to Figures 2 to 4 The shield 13 is provided with an annular groove 134 and a first through hole 135 that are interconnected. When the atomizer 2 is installed on the housing 11, the annular groove 134 is connected to the air intake channel 21. The shield 13 can be moved to the point that the first through hole 135 is connected to the trigger air passage 111 to open the trigger air passage 111, and the shield 13 can be moved to the point that the first through hole 135 is misaligned with the trigger air passage 111 to close the trigger air passage 111. By providing an annular groove 134 and a first through hole 135 on the shield 13, and having the first through hole 135 connected to the annular groove 134, when the atomizer 2 is connected to the shield 13, regardless of the angle to which the atomizer 2 is rotated, the air intake channel 21 inside the atomizer 2 can be connected to the annular groove 134, and then to the first through hole 135. When the first through hole 135 is connected to the trigger airway 111, the air intake channel 21 is also connected to the trigger airway 111, thereby reducing the difficulty of operation for users and improving the user experience.

[0079] In one embodiment, the diameter of the first through hole 135 is greater than or equal to 1 mm and less than or equal to 1.5 mm.

[0080] If the diameter of the first through hole 135 is less than 1 mm, the airflow changes slowly, resulting in insufficient sensitivity of the trigger component 12. If the diameter of the first through hole 135 is greater than 1.5 mm, the user will draw in too much air through the trigger air passage 111, affecting the atomization effect of the aerosol matrix. Therefore, in this embodiment of the invention, the diameter of the first through hole 135 is set to be greater than or equal to 1 mm and less than or equal to 1.5 mm. For example, it can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc., so as to reduce the probability of failing to trigger the trigger component 12 without affecting the atomization effect of the aerosol matrix, and improve the stability of the power supply device 1.

[0081] In one embodiment, reference is made to Figures 2 to 4The power supply device 1 includes a first circuit board 15 and a second circuit board 16 spaced apart. The first circuit board 15 and the second circuit board 16 are electrically connected, and the trigger component 12 is disposed on the second circuit board 16. In related technologies, the power supply device 1 typically contains only one single circuit board, to which the power supply, buttons, and other structures are electrically connected, making the circuit board usually located on the side of the housing 11. In this embodiment of the present invention, by setting the first circuit board 15 and the second circuit board 16 spaced apart, different electrical components within the power supply device 1 can be connected to the nearest circuit board, thereby shortening the wiring length within the power supply device 1, reducing the size of the power supply device 1, and also making the shorter wiring easier to manage and maintain.

[0082] In some alternative embodiments, the second circuit board 16 is disposed at one end of the housing 11 near the atomizer 2, thereby shortening the trigger air path and improving the sensitivity of the trigger assembly 12.

[0083] In one embodiment, reference is made to Figures 2 to 4 The power supply device 1 also includes a button, which is disposed in the housing 11 and electrically connected to the first circuit board 15; and / or, the second circuit board 16 is provided with a second through hole 161, which communicates with the trigger air passage 111 to connect the trigger air passage 111 with the cavity inside the housing 11.

[0084] The button is connected to the first circuit board 15, and the button may include a power switch button, a power adjustment button, etc., so as to control the power supply device 1.

[0085] The second through hole 161 connects the trigger air passage 111 with the cavity inside the housing 11, thereby balancing the air pressure inside the trigger air passage 111, so that when the user inhales, the trigger component 12 can be triggered more smoothly, improving the user experience.

[0086] It should be noted that in this application, "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the related objects before and after it are in an "or" relationship.

[0087] In one embodiment, reference is made to Figure 5 and Figure 6 The housing 11 is provided with a pressure relief hole 113 for connecting the external environment and the trigger air passage 111. The pressure relief hole 113 can be opened at the location of the trigger air passage 111, so that the trigger air passage 111 is directly connected to the external environment; the pressure relief hole 113 can also be opened at other locations on the housing 11, so that the trigger air passage 111 is connected to the external environment through gaps in various places inside the housing 11.

[0088] In one embodiment, reference is made to Figure 5 and Figure 6 The power supply device 1 also includes a waterproof and breathable membrane 17, which is disposed in the pressure relief hole 113 to restrict liquid from entering the cavity of the housing 11. This improves the sealing performance of the power supply device 1 and extends its service life.

[0089] According to a second aspect of the present invention, an electronic atomizing device 3 is provided, with reference to... Figures 1 to 7 The device includes an atomizer 2 and a power supply device 1 as described in the previous embodiment. The atomizer 2 has an inhalation channel 21. The power supply device 1 is detachably connected to the atomizer 2. When the atomizer 2 is installed in the housing 11, the blocking member 13 moves to open the trigger airway 111, so that the user can trigger the trigger component 12 when inhaling through the inhalation channel 21. When the atomizer 2 is detached from the housing 11, the blocking member 13 moves to close the trigger airway 111. The electronic atomizing device 3 includes the aforementioned power supply device 1, and therefore has all the beneficial effects of the aforementioned power supply device 1. The embodiments of this utility model will not be described in detail here.

[0090] In one embodiment, reference is made to Figure 7 The atomizer 2 also includes a pipe section 22, which is positioned corresponding to the first through hole 135 and extends in a direction away from the power supply device 1. The pipe section 22 connects the first through hole 135 and the air intake channel 21. The pipe section 22, which extends in a direction away from the power supply device 1, makes it less likely for the atomizer 2 to become clogged when aerosol matrix deposits inside the atomizer 2, thereby extending the service life of the atomizer 2.

[0091] In one embodiment, reference is made to Figure 7 There are multiple first through holes 135 and multiple pipe sections 22, with multiple pipe sections 22 corresponding to multiple first through holes 135. Multiple first through holes 135 and multiple pipe sections 22 can provide more gas flow paths. Even if some first through holes 135 or pipe sections 22 are blocked, it will not affect the normal use of the electronic atomizing device 3, thus improving stability.

[0092] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0093] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
