Description

Technical Field

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

[0002] The atomizing device uses suction to trigger an airflow switch, which generates a start signal to activate the atomizing component. Under this signal, the atomizing component heats and atomizes the atomizing matrix stored in the liquid reservoir, producing an aerosol. Typically, the airflow switch is located at the bottom of the atomizing device. Since airflow takes a long time to travel within the long air passage, the switch takes a considerable amount of time to detect changes in airflow. This results in a longer timeframe between suction and detection, affecting the switch's sensitivity. Furthermore, the airflow in the sensing air passage flows directly into the atomizing air passage. As the aerosol exits from the atomizing air passage, temperature changes cause condensation, which can easily flow back into the sensing air passage, potentially causing corrosion and short circuits to the airflow switch.

[0042] 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.

[0043] 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.

[0044] 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).

[0045] The atomizing device can atomize water to humidify the air, or it can atomize an atomizing liquid to generate an aerosol. The atomizing liquid can be a liquid or paste-like fragrance, etc. The aerosol produced after atomization can purify or improve air quality. The atomizing liquid can also be plant leaves, tobacco paste, e-liquid, etc., and the aerosol produced after atomization can be inhaled by the user. This application does not limit the object atomized by the atomizing component; it can be selected according to actual needs. In the following embodiments, the atomizing matrix is ​​e-liquid, which atomizes to produce an aerosol that can be inhaled by the user, as an example for illustration.

[0046] The atomizing device includes an atomizing airway and a sensing airway connected to it. The user draws air through the atomizing airway, and external air flows through it. The sensing airway generates airflow changes (e.g., pressure changes). An airflow switch generates a start signal to activate the atomizing component based on these changes. Under this control, the atomizing component heats and atomizes the atomizing matrix to produce an aerosol. However, because the airflow switch is typically located at the bottom of the atomizing device, the airflow travels a relatively long distance through the atomizing airway. This results in a longer time for the airflow switch to detect changes in the sensing airway, affecting its sensitivity. Furthermore, after the atomizing matrix has soaked into the atomizing component, it may not activate promptly. Even after activation, the amount of atomizing matrix soaked into the component is mismatched with its power, further impacting the aerosol's taste.

[0047] To address this, related technologies incorporate atomizing components with higher power. However, it's difficult to match the power of the atomizing component with the amount of atomizing matrix immersed in it, easily leading to burnt coils and affecting the aerosol's flavor. Sensitivity can also be improved by altering the airflow switch; for example, removing the dust filter from the airflow switch makes it easier to sense changes in airflow, but this can easily damage the switch.

[0048] To address the aforementioned issues, this application provides an atomizing device that shortens the length of the sensing airway and improves the sensitivity of the airflow switch.

[0049] Example 1

[0050] See Figures 1-5 As shown, the atomizing device 100 provided in this embodiment includes a housing 10, a mouthpiece 20, an airflow switch 30, and an atomizing component 40.

[0051] The housing 10 has a mouthpiece chamber 11 and an atomizing chamber 12 inside. The mouthpiece chamber 11 is located above the atomizing chamber 12, and the mouthpiece chamber 11 and the atomizing chamber 12 are independent chamber structures. The housing 10 has a mouthpiece opening 13, which is connected to the mouthpiece chamber 11.

[0052] The suction nozzle 20 is disposed inside the suction nozzle cavity 11. The suction nozzle 20 and the portion of the housing 10 containing the suction nozzle cavity 11 together form the suction nozzle, allowing the user to perform a suction action. The suction nozzle 20 is preferably made of a soft material, such as food-grade silicone. The suction nozzle 20 and the suction nozzle cavity 11 can be connected by an interference fit.

[0053] The nozzle assembly 20 is provided with a sensing airway 21, a nozzle airway 22, a connecting airway 23, and a recovery chamber 24. The connecting airway 23 connects the sensing airway 21, the nozzle airway 22, and the recovery chamber 24, allowing fluid to flow sequentially through the sensing airway 21, the recovery chamber 24, and the nozzle airway 22. The connecting airway 23 is connected to the airflow at the nozzle opening 13, and the nozzle airway 22 is connected to the airflow at the atomizing chamber 12. An airflow switch 30 is located in the nozzle assembly 20 and is connected to the airflow at the sensing airway 21. The atomizing component 40 is disposed in the atomizing chamber 12.

[0054] In actual use, the user draws air through the mouthpiece 13, and external air can enter the mouthpiece airway 22 to generate airflow. At the same time, the drawing action through the mouthpiece 13 creates negative pressure in the sensing airway 21 through the connecting airway 23. The airflow switch 30 senses the change in air pressure and generates a start signal through the processor. The processor can then control the atomizing component 40 to start according to the start signal to heat the atomizing matrix and generate aerosol. The generated aerosol flows out of the mouthpiece 13 with the airflow entering the mouthpiece airway 22.

[0055] As the aerosol flows through the nozzle airway 22 and exits from the nozzle opening 13, it is prone to condensation at the nozzle opening 13 due to temperature changes, generating condensate. The condensate flows back to the connecting airway 23 under its own gravity. The recovery chamber 24 is used to collect the condensate that flows back to the connecting airway 23, preventing the condensate from flowing from the connecting airway 23 to the sensing airway 21 and finally to the airflow switch 30, which could cause corrosion of the airflow switch 30.

[0056] In this embodiment, along the flow direction of the fluid sequentially flowing through the sensing airway 21, the recovery chamber 24, and the nozzle airway 22 within the connecting airway 23, the connecting airway 23 is V-shaped, and along the width direction of the nozzle component 20 ( Figure 3 As shown in the X-axis direction, the connecting airway 23 is formed into a V-shape with a gradually decreasing height followed by a gradually increasing height. That is, the height of the connecting airway 23 gradually decreases along the direction from the sensing airway 21 to the recovery chamber 24, and the height of the connecting airway 23 gradually increases along the direction from the recovery chamber 24 to the nozzle airway 22. This arrangement allows the condensate to flow from a high position to a low position along the connecting airway 23 under its own gravity after entering it, and eventually flow to the recovery chamber 24 for recovery. It is less likely to flow to the nozzle airway 22 and the sensing airway 21, and it also shares the condensate flowing to the nozzle airway 22.

[0057] In this application, the nozzle 13 is positioned in the height direction of the atomizing device 100. Figure 3 At one end (top) of the atomizing device 100 (in the Z-axis direction), both the sensing airway 21 and the mouthpiece airway 22 are disposed through the mouthpiece 20 along the height direction of the atomizing device 100. The airflow switch 30 is installed on the side of the mouthpiece 20 facing away from the mouthpiece opening 13. To facilitate the installation of the airflow switch 30, as shown... Figure 3 and Figure 5 As shown, an installation groove 25 is provided on the side of the nozzle component 20 facing away from the nozzle opening 13 where the airflow switch 30 is installed. The sensing air passage 21 passes through the bottom of the installation groove 25. The airflow switch 30 is installed in the installation groove 25, and the sensing end of the airflow switch 30 faces the bottom of the installation groove 25, so that the airflow switch 30 and one end of the sensing air passage 21 are in fluid communication.

[0058] In this embodiment, the airflow switch 30 is a capacitive airflow switch. When the airflow in the sensing airway 21 changes, the capacitance value of the capacitive airflow switch also changes. The processor converts the changing capacitance signal into a start signal, thereby controlling the atomizing component 40 to start.

[0059] In one embodiment, the sensing airway 21 and the mouthpiece airway 22 are parallel to each other and both are parallel to the height direction of the atomizing device 100.

[0060] See Figure 2As shown, the atomizing device 100 provided in this application also includes an inner chamber 50, a display screen 60, a power supply unit 70, and a support assembly 18. The inner chamber 50 is installed inside the housing 10 and fixedly mounted on the support assembly 18. A liquid storage chamber 17 is formed between the outer wall of the inner chamber 50 and the inner wall of the housing 10, and the liquid storage chamber 17 is used to store the atomizing matrix. The display screen 60 has a ring structure and is installed against the inner wall of the inner chamber 50. The atomizing chamber 12 is located inside the inner chamber 50. An energy storage chamber 15, which is independent of the atomizing chamber 12, is also provided in the inner chamber 50. The power supply unit 70 is installed in the energy storage chamber 15 and can provide the electrical energy required for heating the atomizing component 40. It can be considered that the display screen 60, the atomizing chamber 12, and the energy storage chamber 15 are independent of each other in the inner chamber 50 and do not interfere with each other.

[0061] In this embodiment, the inner chamber 50 and the outer shell 10 are made of transparent material, which facilitates observation of the remaining amount of atomized matrix in the liquid storage chamber 17 and also makes it easy to observe the information displayed on the display screen 60. For example, the display screen 60 can display different colors or display changing colors, etc., to enhance the competitiveness of this product.

[0062] In one embodiment, to support the display screen 60 and isolate it from the power supply unit 70 and atomizing component 40 inside the inner compartment 50, a housing 51 is also provided inside the inner compartment 50. The housing 51 has a cylindrical structure, and the display screen 60 is disposed between the outer wall of the housing 51 and the inner wall of the inner compartment 50. Figure 2 As shown, one end of the housing 51 is mounted on the bracket assembly 18, and the end of the housing 51 mounted on the bracket assembly 18 is exposed outside the inner chamber 50. The end of the inner chamber 50 near the bracket assembly 18 is sealed to the display screen 60 by a sealing structure. The atomizing chamber 12 and the energy storage chamber 15 are both formed inside the housing 51.

[0063] The portion of the housing 51 exposed outside the inner chamber 50 is provided with a liquid inlet hole 511. The liquid inlet hole 511 is used to connect the atomizing chamber 12 and the liquid storage chamber 17 for liquid guiding. The atomizing matrix stored in the liquid storage chamber 17 can enter the atomizing chamber 12 through the liquid inlet hole 511 to provide it to the atomizing assembly 40.

[0064] In this embodiment, the atomizing device 100 further includes a tube 80, the inner cavity of which is formed as an atomizing chamber 12. A liquid storage component 19 is installed in the inner cavity of the tube 80. The liquid storage component 19 is provided with an atomizing air passage 191 extending through the axis of the tube 80. The atomizing air passage 191 communicates with the mouthpiece air passage 22. The atomizing component 40 is coaxially installed with the liquid storage component 19 inside the tube 80, and the liquid storage component 19 is located above the atomizing component 40. The tube 80 can be a porous tube, or it can have multiple holes. After the atomizing matrix in the liquid storage chamber 17 enters the atomizing chamber 12 through the liquid inlet 511, it can enter the inner cavity of the tube 80 through the holes or holes in the tube 80 to provide it to the atomizing component 40. The atomizing air passage 191 allows the aerosol generated by the atomization of the atomizing component 40 to flow to the mouthpiece air passage 22. In actual use, a small amount of condensate may flow back into the nozzle air passage 22. The condensate flows along the nozzle air passage 22 to the atomizing air passage 191, where it is stored in the liquid storage component 19, preventing it from flowing further to the atomizing assembly 40. The liquid storage component 19 is made of fiber cotton, which can store the condensate by adsorption under capillary action.

[0065] The atomizing assembly 40 includes an atomizing tube 41, a first liquid guide 42, a heating element 43, and a second liquid guide 44. Both the first and second liquid guides 42 and 44 are hollow cylindrical structures. The second liquid guide 44 is fitted against the inner wall of the tube body 80. The atomizing tube 41 is fitted inside the second liquid guide 44, and the first liquid guide 42 is fitted inside the atomizing tube 41. The heating element 43 is typically a mesh heating wire, fitted against the cavity wall of the hollow space inside the first liquid guide 42. The heating element 43 is electrically connected to the power supply unit 70. Furthermore, the inner cavities of the atomizing tube 41 and the first liquid guide 42 are both connected to the atomizing air passage 191. 1. At least one liquid guiding hole 411 is provided. Part of the first liquid guiding element 42 contacts the second liquid guiding element 44 through the liquid guiding hole 411, or part of the first liquid guiding element 42 is only exposed to the liquid guiding hole 411. The atomizing matrix entering from the liquid inlet hole 511 is stored by the second liquid guiding element 44 and conducted to the first liquid guiding element 42 through the liquid guiding hole 411. The first liquid guiding element 42 is adsorbed by the first liquid guiding element 42 in a capillary manner to wet the heating element 43. The heating element 43 generates heat under the action of the power supply unit 70 to heat and atomize the atomizing matrix to generate aerosol. The aerosol enters the mouthpiece air passage 22 from the atomizing air passage 191 and is output from the mouthpiece opening 13.

[0066] The inner chamber 50 and the tube body 80 have an open structure at the end furthest from the support assembly 18, such as... Figures 3-5As shown, the nozzle component 20 has a first sealing ring 221 and a second sealing ring 222 protruding on the side facing the inner chamber 50. Both the first sealing ring 221 and the second sealing ring 222 are located on the side of the nozzle component 20 facing away from the nozzle opening 13. The first sealing ring 221 surrounds the outer periphery of the second sealing ring 222, and the nozzle air passage 22 passes through the second sealing ring 222. The first sealing ring 221 is used to seal the outer surface of the end of the inner chamber 50 away from the support assembly 18, and has an interference fit with the outer surface of the inner chamber 50 to form a sealed liquid storage cavity 17. The second sealing ring 222 is used to seal the inner surface of the connecting tube body 80 away from the support assembly 18. The second sealing ring 222 is inserted into the inner surface of the tube body 80 to seal it, so that the tube body 80 is sealed by the second sealing ring 222, and the nozzle air passage 22 can remain in communication with the atomizing air passage 191.

[0067] like Figure 2 As shown, the housing 10 is also provided with an air inlet 16. The atomizing airway 191 is connected to the air inlet 16 through the inner cavity of the first liquid guide 42. The user draws air through the mouthpiece 13. External air can enter the atomizing airway 191 through the air inlet 16 and the inner cavity of the first liquid guide 42 to form an airflow. At the same time, due to the user's suction action at the mouthpiece 13, the air in the sensing airway 21 is drawn away, generating a negative pressure. The airflow switch 30 senses the change in air pressure and generates a start signal through the processor. The processor controls the heating element 42 to generate heat to heat the atomizing matrix and generate aerosol. The aerosol flows out of the mouthpiece 13 through the mouthpiece airway 22 along with the airflow in the atomizing airway 191.

[0068] When the user inhales through the mouthpiece 13, the air pressure inside the mouthpiece airway 22 is lower than the air pressure outside the atomizing device 100 because the mouthpiece 13 is being drawn in. The air pressure inside the sensing airway 21, which is connected to the mouthpiece airway 22 through the connecting airway 23, is also lower than the air pressure outside the atomizing device 100. This causes the connecting airway 23 and the sensing airway 21 to form a negative pressure channel during inhalation, thereby causing the airflow switch 30 to sense the change in air pressure.

[0069] As the aerosol flows from the nozzle airway 22 to the nozzle opening 13, the condensate generated by temperature changes flows back and is collected by the recovery chamber 24. Since the connecting airway 23 connects the recovery chamber 24 to the nozzle airway 22, when the user performs a suction action through the nozzle opening 13, a negative pressure is generated in both the recovery chamber 24 and the sensing airway 21 through the connecting airway 23. If the negative pressure is too high, the condensate in the recovery chamber 24 can easily be drawn into the connecting airway 23 and then inhaled by the user through the nozzle opening 13, causing adverse effects. See [link to relevant documentation] for further information. Figure 2 and Figure 3As shown, at least a portion of the sidewall of the suction nozzle 13 extends toward the connecting airway 23 and forms an inclined liquid-blocking portion 131. The connecting airway 23 is defined by the liquid-blocking portion 131 into a narrow air-guiding gap section 132. It can be considered that the gap between the liquid-blocking portion 131 and the sidewall of the connecting airway 23 away from the liquid-blocking portion 131 forms the air-guiding gap section 132. The air-guiding gap section 132 ensures the connectivity of the connecting airway 23, thereby connecting the sensing airway 21, the recovery chamber 24, and the suction nozzle airway 22 to each other. See also... Figure 3 As shown, along the height direction of the nozzle component 20 ( Figure 3 (In the Z-axis direction), the projection area of ​​the liquid-blocking part 131 is located at least between the projection area of ​​the suction nozzle air passage 22 and the projection area of ​​the recovery chamber 24. The liquid-blocking part 131 is used to prevent condensate from being sucked into the suction nozzle 13 under negative pressure. Specifically, when the user draws through the suction nozzle 13 to generate negative pressure on the recovery chamber 24, the condensate stored in the recovery chamber 24 can be blocked by the liquid-blocking part 131.

[0070] Along the height direction of the nozzle 20, the connecting airway 23 is positioned above the sensing airway 21, the recovery chamber 24, and the nozzle airway 22. When the user draws through the nozzle opening 13, the sensing airway 21, the recovery chamber 24, and the nozzle airway 22 all generate an upward negative pressure. Under the action of this negative pressure, and because the suction through the nozzle opening 13 generates an instantaneous negative pressure, and due to the setting of the air guide gap section 132, the instantaneous negative pressure of the condensate transmitted to the recovery chamber 24 through the air guide gap section 132 is relatively large. The condensate in the recovery chamber 24 will be instantaneously sprayed upward along the connection part with the connecting airway 23, and the spray direction is close to the air guide gap section 132. In this application, the projection area of ​​the liquid-blocking part 131 is located at least between the projection area of ​​the recovery chamber 24 and the projection area of ​​the suction nozzle air passage 22. The projection area of ​​the air guide gap section 132 is covered by the projection area of ​​the liquid-blocking part 131. Therefore, under the action of instantaneous negative pressure, the condensate sprayed upward from the connection part between the recovery chamber 24 and the connecting air passage 23 will be sprayed onto the blocking part 131 and blocked by the blocking part 131 to prevent the condensate from being sucked out from the suction nozzle 13.

[0071] In this embodiment, a guide slope 133 is formed on the side of the liquid-blocking part 131 facing away from the suction nozzle 13. When the condensate sprayed from the recovery chamber 24 under negative pressure is specifically sprayed onto the side of the liquid-blocking part 131 facing away from the suction nozzle 13, and the side of the liquid-blocking part 131 facing away from the suction nozzle 13 faces the bottom of the connecting air passage 23 or the connecting part between the recovery chamber 24 and the connecting air passage 23, the guide slope 133 is used to guide the condensate sprayed from the recovery chamber 24 back to the connecting air passage 23, and finally be recovered by the recovery chamber 24 again.

[0072] Since the air guide gap 132 is connected to the mouthpiece 13 via the connecting air passage 23, during the use of the atomizing device 100, the air guide gap 132 may become blocked by foreign objects. In this case, when the user inhales through the mouthpiece 13, the sensing air passage 21 will not generate negative pressure, thus affecting the normal use of the product. In this application, the housing 10 also has a sensing hole 14, which is connected to the airflow of the sensing air passage 21 via the connecting air passage 23. Preferably, the sensing hole 14 is located at the same end of the housing 10 as the mouthpiece 13. When the user inhales through the mouthpiece 13, the user's mouth can simultaneously cover both the mouthpiece 13 and the sensing hole 14, ensuring that even when the air guide gap 132 is blocked by foreign objects, the sensing air passage 21 can generate negative pressure through the sensing hole 14.

[0073] The sensing airway 21, through the connecting airway 23 to the nozzle opening 13, forms the main sensing airway, while the airway from the sensing airway 21 to the sensing hole 14 forms the secondary sensing airway. Both airways can generate negative pressure in the sensing airway 21. In actual use, some aerosol may flow out through the sensing hole 14, leading to condensation at the sensing hole 14. To address this, in this embodiment, the projection of the sensing hole 14 is offset from the projection of the sensing airway 21 along the height direction perpendicular to the nozzle 20, preventing condensation from dripping from the sensing hole 14 into the sensing airway 21. The condensation generated at the sensing hole 14 drips into the connecting airway 23 and flows from the connecting airway 23 into the recovery chamber 24 for recovery.

[0074] Furthermore, along the height direction of the nozzle 20, the recovery chamber 24 is located below the communicating airway 23, and the projection of the sensing hole 14 at least partially overlaps with the projection of the recovery chamber 24, which ensures that the condensate dripping from the sensing hole 14 can drip into the recovery chamber 24 and be recovered.

[0075] See Figure 4 and Figure 5 As shown, the suction nozzle 20 has a recessed connecting groove 231 on the side facing the suction nozzle opening 13. The sensing air passage 21, the suction nozzle air passage 22, and the recovery chamber 24 are all connected to the connecting groove 231. Specifically, the sensing air passage 21 and the suction nozzle air passage 22 both penetrate the bottom of the connecting groove 231. The recovery chamber 24 can be connected to the bottom of the connecting groove 231 through the connecting hole structure. Corresponding to the inclined connecting groove 23, the bottom of the connecting groove 231 is inclined. The connecting groove 231 and the cavity wall of the suction nozzle cavity 11 enclose the connecting groove 23 to form the connecting groove 23.

[0076] In some embodiments, a liquid suction element (not shown in the figure) is also provided in the recovery chamber 24. The liquid suction element is used to adsorb and store the condensate recovered into the recovery chamber 24, restrict the flow of condensate, and prevent condensate from leaking from the sensing hole 14 or the suction nozzle 13 due to improper use.

[0077] See also Figure 5 As shown, the suction nozzle 20 is also provided with a recycling groove 241. The recycling groove 241 is recessed at the bottom of the connecting groove 231 and is connected to the connecting groove 231. Specifically, the recycling groove 241 is formed by recessing from the bottom of part of the connecting groove 231, and the inner cavity of the recycling groove 241 is formed as a recycling cavity 24.

[0078] Example 2

[0079] This application also provides an atomizing device. The difference between the atomizing device provided in this embodiment and that in Embodiment 1 is that the housing is composed of a mouthpiece housing and an atomizing housing. The mouthpiece cavity is disposed inside the mouthpiece housing, and the atomizing cavity is disposed inside the atomizing housing. The mouthpiece housing and the atomizing housing are detachably connected. The mouthpiece component is disposed in the mouthpiece cavity to form a mouthpiece device, and the atomizing component is disposed in the atomizing cavity to form an atomizing host. In other words, the mouthpiece device and the atomizing host are detachably connected to form an atomizing device.

[0080] The housing 10 includes a mouthpiece housing (not shown in the figure) and an atomizing housing (not shown in the figure). The mouthpiece housing and the atomizing housing are detachably connected. The mouthpiece housing is located above the atomizing housing. The mouthpiece housing has a mouthpiece cavity 11 inside, and the atomizing housing has an atomizing cavity 12 inside. The mouthpiece housing also has a mouthpiece opening 13 that communicates with the mouthpiece cavity 11.

[0081] The nozzle assembly 20 is provided with a sensing airway 21, a nozzle airway 22, a connecting airway 23, and a recovery chamber 24. The connecting airway 23 connects the sensing airway 21, the nozzle airway 22, and the recovery chamber 24, allowing fluid to flow sequentially through the sensing airway 21, the recovery chamber 24, and the nozzle airway 22. The connecting airway 23 is connected to the airflow at the nozzle opening 13, and the nozzle airway 22 is connected to the airflow at the atomizing chamber 12. An airflow switch 30 is located in the nozzle assembly 20 and is connected to the airflow at the sensing airway 21. The atomizing component 40 is disposed in the atomizing chamber 12.

[0082] In actual use, the user draws air through the mouthpiece 13, and external air can enter the mouthpiece airway 22 to generate airflow. At the same time, the drawing action through the mouthpiece 13 creates negative pressure in the sensing airway 21 through the connecting airway 23. The airflow switch 30 senses the change in air pressure and generates a start signal through the processor. The processor can then control the atomizing component 40 to start according to the start signal to heat the atomizing matrix and generate aerosol. The generated aerosol flows out of the mouthpiece 13 with the airflow entering the mouthpiece airway 22.

[0083] As the aerosol flows through the nozzle airway 22 and exits from the nozzle opening 13, it is prone to condensation at the nozzle opening 13 due to temperature changes, generating condensate. The condensate flows back to the connecting airway 23 under its own gravity. The recovery chamber 24 is used to collect the condensate that flows back to the connecting airway 23, preventing the condensate from flowing from the connecting airway 23 to the sensing airway 21 and finally to the airflow switch 30, which could cause corrosion of the airflow switch 30.

[0084] Example 3

[0085] This application also provides a suction nozzle device, which can be applied to the atomizing device in the above embodiments, or used as a suction nozzle device independent of the atomizing device, so as to be applied to an atomizing device of any composition. Taking the drawings used in the above embodiments as an example, the suction nozzle device provided in this embodiment includes a housing 10 and a suction nozzle component 20.

[0086] The housing 10 has a suction cavity 11 and a suction port 13, which is connected to the suction cavity 11.

[0087] The suction nozzle 20 is disposed inside the suction nozzle cavity 11. The suction nozzle 20 and the portion of the housing 10 containing the suction nozzle cavity 11 together form a suction nozzle structure, through which the user can perform a suction action. The suction nozzle 20 is preferably made of a soft material, such as food-grade silicone, so that the suction nozzle 20 and the suction nozzle cavity 11 can be connected by an interference fit.

[0088] The mouthpiece 20 is provided with a sensing airway 21, a mouthpiece airway 22, a connecting airway 23, and a recovery chamber 24. The connecting airway 23 connects the sensing airway 21, the mouthpiece airway 22, and the recovery chamber 24, allowing fluid to flow sequentially through these three passages. The connecting airway 23 is connected to the mouthpiece opening 13, and the mouthpiece airway 22 is connected to the atomizing chamber 12 in the atomizing host. The atomizing host includes an airflow switch 30 and an atomizing assembly 40. The airflow switch 30 is connected to the sensing airway 21 and electrically connected to the atomizing assembly 40.

[0089] In actual use, the user draws air through the mouthpiece 13, and external air can enter the mouthpiece airway 22 to generate airflow. At the same time, the drawing action through the mouthpiece 13 creates negative pressure in the sensing airway 21 through the connecting airway 23. The airflow switch 30 senses the change in air pressure and generates a start signal through the processor. The processor can then control the atomizing component 40 to start according to the start signal to heat the atomizing matrix and generate aerosol. The generated aerosol flows out of the mouthpiece 13 with the airflow entering the mouthpiece airway 22.

[0090] As the aerosol flows through the nozzle airway 22 and exits from the nozzle opening 13, it is prone to condensation at the nozzle opening 13 due to temperature changes, generating condensate. The condensate flows back to the connecting airway 23 under its own gravity. The recovery chamber 24 is used to collect the condensate that flows back to the connecting airway 23, preventing the condensate from flowing from the connecting airway 23 to the sensing airway 21 and finally to the airflow switch 30, which could cause corrosion of the airflow switch 30.

[0091] In this embodiment, along the flow direction of the fluid flowing sequentially through the sensing airway 21, the recovery chamber 24, and the suction nozzle airway 22 within the connecting airway 23, the connecting airway 23 is formed into a V-shape with a gradually decreasing height followed by a gradually increasing height. That is, the height of the connecting airway 23 gradually decreases along the direction from the sensing airway 21 to the recovery chamber 24, and gradually increases along the direction from the recovery chamber 24 to the suction nozzle airway 22. This arrangement ensures that after the condensate enters the connecting airway 23, it flows from a high position to a low position along the connecting airway 23 under its own gravity, and eventually flows to the recovery chamber 24 for recovery. It is less likely to flow to the suction nozzle airway 22 and the sensing airway 21, and it also shares the condensate flowing to the suction nozzle airway 22.

[0092] The nozzle 13 is positioned in the height direction of the atomizing device 100. Figure 3 At one end (top) of the atomizing device 100 (in the Z-axis direction), both the sensing airway 21 and the mouthpiece airway 22 are disposed through the mouthpiece 20 along the height direction of the atomizing device 100. The airflow switch 30 is installed on the side of the mouthpiece 20 facing away from the mouthpiece opening 13. To facilitate the installation of the airflow switch 30, as shown... Figure 3 and Figure 5 As shown, an installation groove 25 is provided on the side of the nozzle component 20 facing away from the nozzle opening 13 where the airflow switch 30 is installed. The sensing air passage 21 passes through the bottom of the installation groove 25. The airflow switch 30 is installed in the installation groove 25, and the sensing end of the airflow switch 30 faces the bottom of the installation groove 25, so that the airflow switch 30 and one end of the sensing air passage 21 are in fluid communication.

[0093] When the user inhales through the mouthpiece 13, the air pressure inside the mouthpiece airway 22 is lower than the air pressure outside the atomizing device 100 because the mouthpiece 13 is being drawn in. The air pressure inside the sensing airway 21, which is connected to the mouthpiece airway 22 through the connecting airway 23, is also lower than the air pressure outside the atomizing device 100. This causes the connecting airway 23 and the sensing airway 21 to form a negative pressure channel during inhalation, thereby causing the airflow switch 30 to sense the change in air pressure.

[0094] As the aerosol flows from the nozzle airway 22 to the nozzle opening 13, the condensate generated by temperature changes flows back and is collected by the recovery chamber 24. Since the connecting airway 23 connects the recovery chamber 24 to the nozzle airway 22, when the user performs a suction action through the nozzle opening 13, a negative pressure is generated in both the recovery chamber 24 and the sensing airway 21 through the connecting airway 23. If the negative pressure is too high, the condensate in the recovery chamber 24 can easily be drawn into the connecting airway 23 and then inhaled by the user through the nozzle opening 13, causing adverse effects. See [link to relevant documentation] for further information. Figure 2 and Figure 3 As shown, at least a portion of the sidewall of the suction nozzle 13 extends toward the connecting airway 23 and forms an inclined liquid-blocking portion 131. The connecting airway 23 is defined by the liquid-blocking portion 131 into a narrow air-guiding gap section 132. It can be considered that the gap between the liquid-blocking portion 131 and the sidewall of the connecting airway 23 away from the liquid-blocking portion 131 forms the air-guiding gap section 132. The air-guiding gap section 132 ensures the connectivity of the connecting airway 23, thereby connecting the sensing airway 21, the recovery chamber 24, and the suction nozzle airway 22 to each other. See also... Figure 3 As shown, along the height direction of the nozzle component 20 ( Figure 3 (In the Z-axis direction), the projection area of ​​the liquid-blocking part 131 is located at least between the projection area of ​​the suction nozzle air passage 22 and the projection area of ​​the recovery chamber 24. The liquid-blocking part 131 is used to prevent condensate from being sucked into the suction nozzle 13 under negative pressure. Specifically, when the user draws through the suction nozzle 13 to generate negative pressure on the recovery chamber 24, the condensate stored in the recovery chamber 24 can be blocked by the liquid-blocking part 131.

[0095] Along the height direction of the nozzle 20, the connecting airway 23 is positioned above the sensing airway 21, the recovery chamber 24, and the nozzle airway 22. When the user draws through the nozzle opening 13, the sensing airway 21, the recovery chamber 24, and the nozzle airway 22 all generate an upward negative pressure. Under the action of this negative pressure, and because the suction through the nozzle opening 13 generates an instantaneous negative pressure, and due to the setting of the air guide gap section 132, the instantaneous negative pressure of the condensate transmitted to the recovery chamber 24 through the air guide gap section 132 is relatively large. The condensate in the recovery chamber 24 will be instantaneously sprayed upward along the connection part with the connecting airway 23, and the spray direction is close to the air guide gap section 132. In this application, the projection area of ​​the liquid-blocking part 131 is located at least between the projection area of ​​the recovery chamber 24 and the projection area of ​​the suction nozzle air passage 22. The projection area of ​​the air guide gap section 132 is covered by the projection area of ​​the liquid-blocking part 131. Therefore, under the action of instantaneous negative pressure, the condensate sprayed upward from the connection part between the recovery chamber 24 and the connecting air passage 23 will be sprayed onto the blocking part 131 and blocked by the blocking part 131 to prevent the condensate from being sucked out from the suction nozzle 13.

[0096] In this embodiment, a guide slope 133 is formed on the side of the liquid-blocking part 131 facing away from the suction nozzle 13. When the condensate sprayed from the recovery chamber 24 under negative pressure is specifically sprayed onto the side of the liquid-blocking part 131 facing away from the suction nozzle 13, and the side of the liquid-blocking part 131 facing away from the suction nozzle 13 faces the bottom of the connecting air passage 23 or the connecting part between the recovery chamber 24 and the connecting air passage 23, the guide slope 133 is used to guide the condensate sprayed from the recovery chamber 24 back to the connecting air passage 23, and finally be recovered by the recovery chamber 24 again.

[0097] Since the air guide gap 132 is connected to the mouthpiece 13 via the connecting air passage 23, during the use of the atomizing device 100, the air guide gap 132 may become blocked by foreign objects. In this case, when the user inhales through the mouthpiece 13, the sensing air passage 21 will not generate negative pressure, thus affecting the normal use of the product. In this application, the housing 10 also has a sensing hole 14, which is connected to the airflow of the sensing air passage 21 via the connecting air passage 23. Preferably, the sensing hole 14 is located at the same end of the housing 10 as the mouthpiece 13. When the user inhales through the mouthpiece 13, the user's mouth can simultaneously cover both the mouthpiece 13 and the sensing hole 14, ensuring that even when the air guide gap 132 is blocked by foreign objects, the sensing air passage 21 can generate negative pressure through the sensing hole 14.

[0098] The sensing airway 21, through the connecting airway 23 to the nozzle opening 13, forms the main sensing airway, while the airway from the sensing airway 21 to the sensing hole 14 forms the secondary sensing airway. Both airways can generate negative pressure in the sensing airway 21. In actual use, some aerosol may flow out through the sensing hole 14, leading to condensation at the sensing hole 14. To address this, in this embodiment, the sensing hole 14 and the sensing airway 21 are misaligned along the height direction perpendicular to the nozzle 20 to prevent condensation from dripping from the sensing hole 14 into the sensing airway 21. The condensation generated at the sensing hole 14 drips into the connecting airway 23 and flows from the connecting airway 23 into the recovery chamber 24 for recovery.

[0099] Furthermore, along the height direction of the nozzle 20, the recovery chamber 24 is located below the communicating airway 23, and the projection of the sensing hole 14 at least partially overlaps with the projection of the recovery chamber 24, which ensures that the condensate dripping from the sensing hole 14 can drip into the recovery chamber 24 and be recovered.

[0100] See Figure 4 and Figure 5As shown, the suction nozzle 20 has a recessed connecting groove 231 on the side facing the suction nozzle opening 13. The sensing air passage 21, the suction nozzle air passage 22, and the recovery chamber 24 are all connected to the connecting groove 231. Specifically, the sensing air passage 21 and the suction nozzle air passage 22 both penetrate the bottom of the connecting groove 231. The recovery chamber 24 can be connected to the bottom of the connecting groove 241 through the connecting hole structure. Corresponding to the inclined connecting groove 23, the bottom of the connecting groove 231 is inclined. The connecting groove 231 and the cavity wall of the suction nozzle cavity 11 enclose the connecting groove 23 to form the connecting groove 23.

[0101] In some embodiments, a liquid suction element (not shown in the figure) is also provided in the recovery chamber 24. The liquid suction element is used to adsorb and store the condensate recovered into the recovery chamber 24, restrict the flow of condensate, and prevent condensate from leaking from the sensing hole 14 or the suction nozzle 13 due to improper use.

[0102] See also Figure 5 As shown, the suction nozzle 20 is also provided with a recycling groove 241. The recycling groove 241 is recessed at the bottom of the connecting groove 231 and is connected to the connecting groove 231. Specifically, the recycling groove 241 is formed by recessing from the bottom of part of the connecting groove 231, and the inner cavity of the recycling groove 241 is formed as a recycling cavity 24.

[0103] In summary, in the atomizing device provided in this application, both the sensing airway and the airflow switch are located on the mouthpiece. The sensing airway is connected to the mouthpiece airway and the mouthpiece opening via a connecting airway. The airflow switch is positioned relatively closer to the mouthpiece opening, allowing it to quickly detect changes in negative pressure in the sensing airway after suction. Compared to related technologies where the airflow switch is located at the bottom of the atomizing device, this significantly shortens the length of the sensing airway, thereby improving the sensitivity of the airflow switch. Simultaneously, the inclusion of a recovery chamber connected to the connecting airway allows for the recovery of any condensate that flows back, preventing corrosion or damage to the airflow switch, or even automatic restart.
