The first valve disc and the second valve disc are installed opposite each other on opposite sides of the valve body so that the first valve disc, the second valve disc, and the valve body form the fluid channel.

[0016] The first lip and the second lip are respectively formed by extending opposite ends of the first valve disc and the second valve disc away from the valve body;

[0017] Specifically, when the fluid medium flows from the fluid channel along the direction from the inlet end to the outlet end, the first valve disc and the second valve disc separate to open the outlet slit; or, when the fluid medium flows from the outside of the fluid channel along the direction from the outlet end to the inlet end, the first valve disc and the second valve disc converge to close the outlet slit.

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] The atomizing device can be applied in the medical field, for example, to atomize liquid drugs for easier absorption. It can also be applied in the fumigation field, for example, to atomize perfumes to purify or improve air quality. Of course, it can also be used to heat plant leaves, tobacco paste, tobacco oil, etc. to produce aerosols for users to consume. This application does not limit the objects atomized by the atomizing device; the specific selection can be made according to actual needs.

[0042] In the following embodiments, the atomization device is used to atomize plant leaves, tobacco paste, e-liquid, etc. to generate aerosols as an example. The atomization matrix is ​​plant leaves, tobacco paste, e-liquid, etc.

[0043] In related technologies, atomizing devices include a liquid storage structure, an atomizing core, and an airflow sensor. The liquid storage structure stores the atomizing matrix, and the atomizing core heats and atomizes the matrix to produce an aerosol. The aerosol is output through an air passage. During the output process, the aerosol condenses and adheres to the air passage due to temperature differences, producing condensate. The outlet of the air passage is usually equipped with a nozzle, which the user uses to draw out the aerosol. During the drawing process, "backflow" inevitably occurs, causing the condensate to flow back under the influence of the backflowing airflow.

[0044] The air passage can run through the liquid storage structure. The airflow sensor is usually located below the air passage and is fluidly connected to it. The airflow sensor is used to sense changes in airflow within the air passage to activate the atomizing core to heat the atomizing matrix. Backflowing condensate, after wetting the airflow sensor, can cause it to short-circuit or self-start, affecting the normal operation of the atomizing device.

[0045] To prevent condensate backflow, a liquid suction device is usually installed in the air passage. This device is preferentially placed in locations within the air passage where condensate is likely to form, and it absorbs the condensate to prevent backflow. However, the suction device has limited suction capacity. When it reaches saturation, condensate overflows from the device, and backflow can still occur due to the backflushing airflow.

[0046] To address the aforementioned issues, this application provides an atomizing device with a one-way valve installed in the air passage. This one-way check prevents the backflow of the airflow from backflushing the condensate, thus avoiding condensate backflow.

[0047] See Figures 1-5 As shown, the atomizing device provided in this embodiment includes a liquid storage chamber 10, an atomizing core 20, and an air outlet assembly 30. The liquid storage chamber 10 is configured to store the atomizing matrix, and the atomizing core 20 is configured to receive and atomize the atomizing matrix to generate an aerosol.

[0048] The liquid storage chamber 10 is provided with an atomizing channel 11, and the atomizing core 20 is installed in the atomizing channel 11.

[0049] In this embodiment, the atomizing core 20 heats the atomizing matrix by heating. The liquid storage chamber 10 is provided with a liquid storage component 111, which can be made of materials such as fiber cotton. The atomizing matrix is ​​usually in liquid form, and the liquid storage component 111 can store the atomizing matrix by adsorption. The atomizing core 20 includes an atomizing tube 21, a liquid guiding component 22, and a heating component 23. The atomizing channel 11 is disposed through the liquid storage component 111. The atomizing tube 21 is installed with an opening (not shown in the figure). The heating component 23 is usually a spiral heating wire and is installed inside the liquid guiding component 22. The liquid guiding component 22 is installed inside the atomizing tube 21, and part of the liquid guiding component 22 can extend to the outside of the atomizing tube 21 through the opening. The part of the liquid guiding component 22 extending to the outside of the atomizing tube 21 contacts the liquid storage component 111. The liquid guiding component 22 is also made of fiber cotton material. The atomizing matrix can be transferred to the liquid guiding component 22 through capillary action. The heating component 23 can then heat and atomize the atomizing matrix to generate an aerosol. The generated aerosol can be output through the atomizing channel 11.

[0050] The aerosol outlet assembly 30 is connected to the liquid storage tank 10. The aerosol output through the atomization channel 11 can be output through the aerosol outlet assembly 30 for user use.

[0051] In this application, see Figures 1-3 As shown, this atomizing device also includes a housing 40, which cooperates with the air outlet assembly 30 to form an installation space for installing the liquid storage chamber 10. An air inlet channel 41 is also provided on the housing 40, which is in communication with the atomizing channel 11. An airflow sensor 50 is also provided inside the housing 40. The airflow sensor 50 is in fluid communication with the air inlet channel 41 and is electrically connected to the heating element 23 in the atomizing core 20. It can sense changes in airflow and generate a start signal to activate the heating element 23 upon sensing a change in airflow.

[0052] In some embodiments, a power supply unit 60 is also provided inside the housing 40. The power supply unit 60 can provide the heating element 23 with the electrical energy required for heating. The power supply unit 60 can be a rechargeable battery. The atomizing device is also provided with a charging port 61 (e.g., Figure 3 As shown, power can be supplied to the power supply unit 60 through the charging port 61.

[0053] In actual use, the user performs a suction action through the air outlet component 30. External gas can enter the atomization channel 11 through the air inlet channel 41. The airflow sensor 50 senses the change in airflow and generates a start signal to start the heating element 23. The heating element 23 heats the atomization matrix transferred through the liquid guide 22 to generate aerosol. The aerosol can be output from the air outlet component 30 through the atomization channel 11 with the airflow. During the output process, the aerosol condenses due to the temperature difference and adheres to the channel wall of the air outlet component 30 and / or the atomization channel 11 to form condensate.

[0054] When the user performs a suction action through the air outlet component 30, after frequent or repeated "inhalation" actions, an "exhalation" action inevitably occurs, which backflushs the air outlet component 30 and the atomization channel 11. This backflush forces the condensate to flow back. When the backflowing condensate gradually wets the airflow sensor 50, it will cause the airflow sensor 50 to short-circuit, resulting in the heating element 23 being unable to heat, or even causing the airflow sensor 50 to self-start, further leading to the problem of the heating element 23 burning and scorching, affecting the normal use of the atomization device.

[0055] In this application, the air outlet assembly 30 includes a one-way valve 31, which has an inlet end 311 and an outlet end 312. The inlet end 311 is connected to the atomizing channel 11, and the outlet end 312 can discharge aerosol. In actual use, the user performs an inhalation action through the outlet end 312. The one-way valve 31 is configured to only allow the fluid medium to flow from the inlet end 311 to the outlet end 312. Conversely, the one-way valve 31 can prevent the fluid medium from flowing from the outlet end 312 to the inlet end 311, preventing the fluid medium from flowing back into the one-way valve 31 from the inlet end 311, and avoiding the reverse flow of condensate caused by the user's exhalation. The fluid medium is an aerosol mixed with airflow, as well as the reverse airflow generated by the user's exhalation.

[0056] See Figures 3-5 As shown, the one-way valve 31 has an internal fluid channel 310, with an inlet end 311 and an outlet end 312 at its two ends. The outlet end 312 of the one-way valve 31 also has an outlet slit 313, which communicates with the fluid channel 310. The outlet slit 313 can be considered as a gap formed at the outlet end 312 of the one-way valve 31. The outlet slit 313 has two states: open and closed. In the open state, the outlet slit 313 is opened to discharge the fluid medium. In the closed state, the outlet slit 313 is closed to prevent backflow.

[0057] In this embodiment, the radial dimension of the fluid channel 310 gradually decreases along the direction from the air inlet end 311 to the air outlet end 312, so that the fluid channel 310 is formed into an approximately conical shape.

[0058] The one-way valve 31 can undergo elastic deformation. For example, the one-way valve 31 is made of food-grade silicone material through injection molding. This elastic deformation allows for outward expansion when the internal pressure of the fluid channel 310 is greater than the external pressure. During this outward expansion, the vent slit 313 is opened, forming an open state. Conversely, when the internal pressure of the fluid channel 310 is less than the external pressure, it undergoes inward contraction. During this inward contraction, the vent slit 313 is closed, forming a closed state. Here, the outside of the fluid channel 310 refers to the outer surface of the one-way valve 31.

[0059] When a user performs an inhalation action, causing the aerosol to flow along the airflow from the inlet end 311 to the outlet end 312 within the fluid channel 310, the internal pressure of the fluid channel 310 is greater than the external pressure. However, when a user exhales, causing the external airflow to blow onto the outer surface of the one-way valve 31, the internal pressure of the fluid channel 310 is less than the external pressure.

[0060] See Figure 6 As shown, the horizontal dashed line with an arrow indicates that the fluid medium flows in the fluid channel 310 along the direction from the inlet end 311 to the outlet end 312, causing the one-way valve 31 to deform outward. The two vertical dashed lines with arrows indicate that when the outlet slit 313 deforms outward due to the one-way valve 31, the opposite sides of the outlet slit 313 separate from each other, so that the outlet slit 313 is in an open state, and the fluid medium is discharged through the open outlet slit 313.

[0061] See Figure 7 As shown, the horizontal dashed line with an arrow indicates that the reverse airflow from the user blows along the direction from the outlet end 312 to the inlet end 311 towards the outer surface of the one-way valve 31, causing the one-way valve 31 to deform inward. The vertical dashed lines with arrows in opposite directions indicate the direction in which the opposite sides of the outlet slit 313 come into contact with each other when the one-way valve 31 deforms inward, thus keeping the outlet slit 313 in a closed state and preventing the backflow airflow from entering the atomizing channel 11 through the fluid channel 310 via the outlet slit 313.

[0062] In this application, the one-way valve 31 is used to expand outward to open the outlet slit 313 when the internal pressure of the fluid channel 310 is greater than the external pressure, so that the aerosol can be output through the open outlet slit 313. Alternatively, the one-way valve 31 is used to contract inward to close the outlet slit 313 when the internal pressure of the fluid channel 310 is less than the external pressure, so as to prevent the reverse airflow from entering the atomization channel 11 through the fluid channel 310 via the outlet slit 313.

[0063] In one embodiment of this application, an approximately conical fluid channel 310 is used, which can accelerate the fluid medium from the open outlet slit 313. At the same time, when the fluid medium flows in the direction from the inlet end 311 to the outlet end 312, it can provide an outward expansion force to the check valve 31, forcing the check valve 31 to undergo outward expansion deformation.

[0064] See Figures 5-7 As shown, the outlet end 312 of the one-way valve 31 is also provided with a first lip 314 and a second lip 315. The first lip 314 and the second lip 315 extend from both sides of the outlet slit 313 toward the fluid channel 310. The first lip 314 and the second lip 315 are configured to separate from each other when the internal pressure of the fluid channel 310 is greater than the external pressure. At this time, the outlet slit 313 is in an open state. Alternatively, the first lip 314 and the second lip 315 are configured to fit together when the internal pressure of the fluid channel 310 is less than the external pressure. At this time, the outlet slit 313 is in a closed state.

[0065] The first lip 314 and the second lip 315, which fit together, can form a sealed state when they fit together, thereby improving the sealing performance of the vent slit 313 when it is in a closed state.

[0066] To achieve a mutually fitted state, the first lip 314 and the second lip 315 can both be flat, or the first lip 314 and the second lip 315 can have complementary shapes to achieve a sealing effect when they are fitted together.

[0067] See Figures 4-7 As shown, the one-way valve 31 includes a valve body 316, a first valve disc 317 and a second valve disc 318. The first valve disc 317 and the second valve disc 318 are installed opposite each other on opposite sides of the valve body 316 so that the first valve disc 317, the second valve disc 318 and the valve body 316 form a fluid channel 310.

[0068] The first lip 314 and the second lip 315 are respectively formed by extending from the ends of the first valve flap 317 and the second valve flap 318 away from the valve body 316, and the ends of the first valve flap 317 and the second valve flap 318 away from the valve body 316 are the ends where the air outlet end 313 is provided.

[0069] When the user performs suction, the fluid medium flows in the fluid channel 310 along the direction from the inlet end 311 to the outlet end 313. During this process, the inner surface of the first valve disc 317 and the inner surface of the second valve disc 318 are subjected to the following conditions: Figure 6The force provided by the fluid medium causes an outward expansion deformation, which separates the first lip 314 from the second lip 315. Then the vent slit 313 is in an open state, and the fluid medium is output through the open vent slit 313.

[0070] When the user exhales, the reverse airflow flows from the outside of the fluid channel 310 along the direction from the outlet end 312 to the inlet end 311 and blows towards the outer surfaces of the first valve disc 317 and the second valve disc 318. The first valve disc 317 and the second valve disc 318 undergo a deformation that brings them together, causing the first lip 314 and the second lip 315 to fit together. The outlet slit 313 is then in a closed state, and the reverse airflow cannot enter the atomizing channel 11 through the fluid channel 310 via the outlet slit 313.

[0071] See Figures 4-7 As shown, along the direction from the inlet end 311 to the outlet end 313, the distance between the inner surfaces of the first valve disc 317 and the second valve disc 318 gradually decreases to form a fluid channel 310 with an approximately conical shape. The first lip 314 and the second lip 315 can be formed by extending outward and relative to each other from the position where the distance between the first valve disc 317 and the second valve disc 318 is the smallest, wherein the outward extension direction is towards the outside of the one-way valve 31.

[0072] See also Figures 4-7 As shown, along the direction from the air inlet end 311 to the air outlet end 312, the distance between the outer surface of the first valve disc 317 and the outer surface of the second valve disc 318 gradually decreases, which can ensure that the reverse airflow provides a force for the first valve disc 317 and the second valve disc 318 to mutually converge and deform when blowing towards the outer surfaces of the first valve disc 317 and the second valve disc 318.

[0073] The one-way valve 31 also includes a connecting flange 319, which is connected to the valve body 316. See [link / reference] Figure 2 and Figure 3 As shown, the outer wall of the liquid storage tank 10 is also provided with an air outlet pipe 12. The inner cavity of the air outlet pipe 12 is connected to the atomization channel 11. The connecting flange 319 is sleeved on the periphery of the air outlet pipe 12, thereby connecting the fluid channel 310 and the atomization channel 11.

[0074] In some embodiments, to improve the sealing between the connecting flange 319 and the outlet pipe 12 and prevent leakage of condensate or aerosol, a sealing structure is also provided on the inner wall of the connecting flange 319 and / or the outer wall of the outlet pipe 12. For example... Figures 5-7 As shown, a sealing structure 3191 is provided on the inner wall of the connecting flange 319. The sealing structure 3191 is provided around the inner wall of the connecting flange 319 and protrudes from the inner wall of the connecting flange 319.

[0075] See Figures 1-4 As shown, the air outlet assembly 30 also includes a mounting member 32, which has a mounting cavity 321. One side of the mounting member 32 is provided with a mounting port 322, and the other side of the mounting member 32 is provided with an air outlet 323. The mounting port 322 is connected to the liquid storage tank 10. A one-way valve 31 is disposed inside the mounting cavity 321. The air outlet end 312 of the one-way valve 31 is connected to the air outlet 323, so that the aerosol output through the air outlet slit 313 disposed at the air outlet end 312 is output from the air outlet 313.

[0076] In some embodiments, the air outlet assembly 30 further includes a liquid suction member 33, which is disposed inside the mounting cavity 321 and surrounds the periphery of the air inlet end 312, and can absorb the condensate seeping through the gap between the air inlet end connecting flange 319 and the air outlet pipe 12.

[0077] To facilitate user operation, the mounting part 32 is provided with a suction nozzle 324, and an air outlet 323 is provided on the suction nozzle 324, allowing the user to perform suction through the suction nozzle 324.

[0078] In summary, the atomizing device provided by this utility model, through the setting of a one-way valve, can ensure that the fluid medium can be output in the direction from the air inlet to the air outlet, avoiding the reverse airflow from entering the atomizing channel, and thus preventing the condensate from flowing back under the action of the reverse airflow.
