Description

Technical Field

[0001] This invention belongs to the field of food technology, specifically relating to a functional drinking spout. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Different fields and users consume different substances, requiring specific nozzles to match them. On the one hand, nozzles have very low versatility and cannot be matched with other substances. On the other hand, factories need designers to provide different designs and ideas to avoid conflicts of interest. The total cost of mold opening, production, and designer expenses for multiple nozzles is too high, increasing the burden on enterprises and manufacturers. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a functional suction nozzle, comprising:

[0005] The housing has a hollow structure, with one end being a suction port for user use and the other end being an air inlet, and a gas passage between the suction port and the air inlet.

[0006] A functional liquid storage device is disposed within the housing and is used to contain the functional liquid;

[0007] An injection assembly is disposed within the housing and near the air inlet, and the injection assembly is configured to allow unidirectional communication between the functional fluid reservoir and the injection assembly under pressure.

[0008] This application provides a functional mouthpiece in which a functional liquid flows out from a storage container along an injection assembly under pressure, and can be ingested by the user. The functional liquid is a liquid that provides value to the user. The functional mouthpiece provided by this invention can be applied to different industries, with its use and replacement determined according to the user's needs. The functional liquid can be a medical functional liquid, such as commonly used nebulizers like saline, corticosteroids, bronchodilators, anticholinergics, and expectorants; it can also be an extract of traditional Chinese medicine or other food ingredients, such as mint, patchouli, or agarwood flavors. Traditional Chinese medicine has its own medicinal properties, and users can choose the corresponding herbal extract functional liquid according to their needs, which is beneficial to their health. The functional liquid can also be e-liquid, similar to electronic cigarettes or tobacco products after being filled with e-liquid. Furthermore, the functional liquid can be a flavoring liquid, such as fruit or vegetable flavors. The flavoring liquid can be mixed with tobacco products to improve the taste of the smoke and also achieve the effect of improving quality and reducing harm. The functional nozzles provided in this application have a wide range of applications, with significant differences across various fields. The strong versatility of the functional nozzles can reduce the number of mold openings, thereby reducing production costs and designer expenses.

[0009] The injection component and functional fluid reservoir are located inside the housing to prevent contamination of the injection component, which would affect the function and taste of the functional fluid. It also avoids the problem of functional fluid leakage due to accidental contact, such as when the fluid is placed in a pocket and collided with a key, causing the injection component to be triggered and the functional fluid to leak out.

[0010] Under pressure, the injection component creates a one-way connection between the functional fluid reservoir and the injection component. When the pressure is lost, the connection between the injection component and the functional fluid reservoir is cut off, preventing the functional fluid from flowing freely and improving the user experience.

[0075] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0076] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0077] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0078] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0079] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0080] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0081] like Figures 1 to 5 As shown, the present invention provides a functional suction nozzle 100, comprising:

[0082] The shell 1 is a hollow structure. One end of the shell 1 is a suction port 11, and the other end is an air inlet 12. The gas passage 13 is between the suction port 11 and the air inlet 12.

[0083] Functional liquid storage component 2 is disposed inside the housing 1 and is used to contain functional liquid;

[0084] The injection component 3 is disposed inside the housing 1 and near the air inlet 12. The injection component 3 is configured to allow the functional liquid storage component 2 to be unidirectionally connected to the injection component 3 under pressure.

[0085] This application provides a functional mouthpiece 100, in which a functional liquid flows out from a functional liquid storage container along an injection assembly under pressure, and can be ingested by the user. The functional liquid is a liquid that provides value to the user. The functional mouthpiece 100 provided by this invention can be applied to different industries, with its use and replacement determined according to the user's needs. The functional liquid can be a medical functional liquid, such as physiological saline, glucocorticoids, bronchodilators, anticholinergic drugs, expectorants, etc., commonly used in nebulization; the functional liquid can be an extract of traditional Chinese medicine or other food ingredients, such as mint, patchouli, or agarwood flavors. Traditional Chinese medicine has its own medicinal properties, and users can choose the corresponding traditional Chinese medicine extract functional liquid according to their needs, which is beneficial to the user's health. The functional liquid can be e-liquid, similar to electronic cigarettes or tobacco products after being filled with e-liquid. The functional liquid can be a flavoring liquid, such as fruit or vegetable flavors, which can be mixed with tobacco products to improve the taste of the smoke. The functional nozzle 100 provided in this application has a wide range of applications, with significant differences across various fields. The strong versatility of the functional nozzle 100 can reduce the number of mold openings, thereby reducing production costs and designer expenses.

[0086] The injection component and functional fluid reservoir are located inside the housing to prevent contamination of the injection component, which would affect the function and taste of the functional fluid. It also avoids the problem of functional fluid leakage due to accidental contact, such as when the fluid is placed in a pocket and collided with a key, causing the injection component to be triggered and the functional fluid to leak out.

[0087] Under pressure, the injection component creates a one-way connection between the functional fluid reservoir and the injection component. When the pressure is lost, the connection between the injection component and the functional fluid reservoir is cut off, preventing the functional fluid from flowing freely and improving the user experience.

[0088] The functional suction nozzle 100 provided in this application can be used alone or in conjunction with the functional liquid carrier 6. For example... Figure 5As shown, the functional liquid carrier 6 can be a tobacco product, such as a cigarette or tobacco cartridge including a tobacco section and a filter tip, or it can be a cotton core, felt, sheet, or dried granules. When the functional liquid carrier 6 is a tobacco cartridge or a cigarette, the tobacco cartridge may or may not contain tobacco liquid. When the functional liquid carrier 6 is inserted into the housing 1 through the air inlet 12, friction is generated between the functional liquid carrier 6 and the injection component 3. This friction is converted into pressure on the injection component 3, which is the force that enables unidirectional communication between the injection component 3 and the functional liquid storage unit 2. After unidirectional communication, the functional liquid in the functional liquid storage unit 2 can enter the functional liquid carrier 6 through the injection component 3. The entire outflow of functional liquid can be completed simply by inserting the functional liquid carrier 6. The operation is very simple, and there is no need to set up additional buttons or drive mechanisms to push the functional liquid into the functional liquid carrier 6, which simplifies the structure and reduces production and manufacturing costs.

[0089] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the functional liquid storage component 2 includes a body 21, which is a hollow structure used to contain the functional liquid. One end of the body 21 has an interface 22, and an injection assembly 3 is movably connected to the interface 22. The injection assembly 3 is configured to communicate unidirectionally with the body 21 under pressure. This movable connection between the injection assembly 3 and the interface 22 reduces processing and manufacturing costs, facilitates mold manufacturing, and also facilitates the filling of the functional liquid. After filling, the injection assembly 3 and the functional liquid storage component 2 are assembled. Furthermore, to prevent leakage from the functional liquid storage component 2, a seal can be provided at the interface 22 between the injection assembly 3 and the functional liquid storage component 2. The seal can be foam or a rubber ring. The movable connection between the injection assembly 3 and the functional liquid storage component 2 can be a threaded fit, screw fit, snap-fit ​​fit, rotational fit, magnetic fit, etc.

[0090] In some embodiments of the present invention, such as Figures 3 to 5 As shown, a one-way structure 32 is required to achieve unidirectional injection of the functional liquid. Specifically, the injection assembly 3 includes an injection tube 31 and a one-way structure 32. The one-way structure 32 is connected to the body 21 and is configured to maintain unidirectional communication between the body 21 and the injection tube 31 under pressure, allowing the functional liquid to flow out for consumption by the user. The one-way structure 32 can serve as an intermediary connecting the injection tube 31 and the body 21, possessing both connection and unidirectional functions, or it can have only a unidirectional function, with the injection tube 31 directly connected to the body 21.

[0091] In some embodiments of the present invention, such as Figures 3 to 4As shown, in one embodiment, the one-way structure 32 serves as an intermediary connecting the injection tube 31 and the body 21, possessing both connecting and one-way functions. The injection tube 31 is connected to the body 21 via the one-way structure 32. Specifically, the injection tube 31 has a stepped hole 311. The one-way structure 32 includes a guide 321, a first one-way member 322, a second one-way member 323, and a first elastic member 324. The guide 321 is sealed to the interface 22. A receiving cavity 328 is formed between the guide 321, the injection tube 31, and the functional liquid storage device 2. The injection tube 31 passes through the guide 321. The first one-way member 322 is located between the interface 22 and the injection tube 31, and its size is larger than that of the interface 22. The second one-way member 323 is located within the stepped hole 31. Within 1, and the size of the second one-way member 323 is larger than the minimum size of the stepped hole 311, the first elastic member 324 is sandwiched between the first one-way member 322 and the stepped hole 311. When the injection tube 31 is connected to the functional liquid storage device 2, the first elastic member 324 is under force. The first one-way member 322 seals the interface 22. The second one-way member 323 connects the accommodating cavity 328 and the injection tube 31. When the injection tube 31 is not connected to the functional liquid storage device 2, the first one-way member 322 connects the interface 22 and the accommodating cavity 328. The second one-way member 323 seals the accommodating cavity 328. Under pressure, the injection tube 31 moves closer to the body 21, reducing the volume of the accommodating cavity 328 and increasing the pressure. The first one-way component 322 cannot move under the action of the first elastic component 324, maintaining the sealed state of the interface 22. Under the impact of the functional liquid, the second one-way component 323 connects the accommodating cavity 328 and the injection tube 31, allowing the functional liquid to flow out from the injection tube 31 for consumption by the user. When the pressure is lost, the injection tube 31 returns to its initial state under the action of the first elastic component 324, increasing the volume of the accommodating cavity 328 and creating a negative pressure. Under the action of the negative pressure, the first one-way component 322 no longer seals the interface 22, and the functional liquid in the body 21 enters the accommodating cavity 328 from the body 21 to replenish the functional liquid that just flowed out. This process repeats, achieving automatic outflow and replenishment of the functional liquid.

[0092] In some embodiments of the present invention, such as Figure 5As shown, in one embodiment, the one-way structure 32 has only a one-way function, and the injection tube 31 is directly connected to the body 21. Specifically, the one-way structure 32 includes a second elastic member 325, a third one-way member 326, and a trigger member 327. The second elastic member 325 is connected inside the body 21, and the third one-way member 326 is connected to the end of the second elastic member 325 near the injection tube 31. The size of the third one-way member 326 is larger than the size of the interface 22. The trigger member 327 is connected to the end of the third one-way member 326 away from the second elastic member 325, and the trigger member 327 is located inside the injection tube 31 and extends outside the injection tube 31. When the injection tube 31 is connected to the functional liquid storage device 2, the second elastic member 325 is under force, and the third one-way member 326 is separated from the interface 22. When the injection tube 31 is not connected to the functional liquid storage device 2, the third one-way member 326 seals the interface 22. When the trigger 327 is subjected to pressure, it moves toward the body 21, causing the third one-way component 326 and the second elastic component 325 to move toward the body 21. The third one-way component 326 separates from the interface 22, and the body 21 connects with the injection tube 31. The functional fluid flows out from the injection tube 31. When the pressure is lost, the third one-way component 326 returns to its initial state under the action of the second elastic component 325 and seals the interface 22 again. The functional fluid no longer flows out. This process is repeated to achieve automatic flow of the functional fluid.

[0093] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the sealing side of the first one-way member 322, the second one-way member 323, and the third one-way member 326 is all set as an arc-shaped surface. For example, the first one-way member 322, the second one-way member 323, and the third one-way member 326 are all spheres, ellipsoids, or hemispheres. The first elastic member 324 and the second elastic member 325 are both columnar springs.

[0094] In some embodiments of the present invention, the functional fluid is continuously consumed as the user uses it. When the fluid is depleted or about to be depleted, the user can choose to purchase a new functional nozzle 100. To save on purchase costs, a functional fluid refill port is provided on the main body 21, and a through hole is provided on the housing 1 at the position corresponding to the functional fluid refill port. The user can choose to purchase a functional fluid refill kit and fill the functional fluid himself. The functional fluid refill port is designed to open in one direction under pressure to avoid leakage after filling.

[0095] In some embodiments of the present invention, during user use, the injection component 3 will continuously move relative to the body 21. In order to ensure the reliability and service life of the structure, the body 21 adopts a rigid structure.

[0096] In some embodiments of the present invention, as described above, the body 21 has a hollow structure, with an interface 22 at one end and the other end can be directly configured as a closed structure. In other embodiments, such as Figure 4As shown, the main body 21 can be configured as a negative pressure bottle structure. The functional liquid storage component 2 also includes a piston component 23. The end of the main body 21 away from the interface 22 is configured as an open structure. The piston component 23 is connected to the end of the main body 21 away from the interface 22 and is slidably connected to the inner side of the main body 21. The negative pressure bottle form is for a unidirectional structure 32 including a first unidirectional component 322, a second unidirectional component 323, and a first elastic component 324. Due to the continuous generation of negative pressure, the piston component 23 continuously moves towards the interface 22 under the action of negative pressure. The piston can completely squeeze out the functional liquid in the functional liquid storage component 2, avoiding liquid residue. In addition, the negative pressure bottle can also control the amount of functional liquid flowing out each time, avoiding the problem of excessive flow causing waste and insufficient flow affecting the taste, indirectly improving the user experience.

[0097] In some embodiments of the present invention, and in other embodiments, the body 21 may be configured as a flexible structure, i.e., having a certain amount of deformation. Flexible structures have higher adaptability when there is a large temperature difference.

[0098] In some embodiments of the present invention, when a flexible structure is used, in addition to the functional fluid flowing out of the injection tube 31 through pressure, a press-opening is provided on the housing 1 in the area corresponding to the main body 21, allowing the user to manually squeeze the main body 21 to assist in the injection of the functional fluid. There may be one press-opening, or two or more. In one embodiment, there are two press-openings, symmetrically arranged on both sides of the housing 1, facilitating the user to apply pressure to the main body 21.

[0099] In some embodiments of the present invention, in order to facilitate users to check the usage status of the functional liquid, the main body 21 can be set as a light-transmitting element, and a light-transmitting area is provided on the housing 1 corresponding to the area of ​​the main body 21. By superimposing the light-transmitting area and the light-transmitting element, the usage status of the functional liquid can be clearly seen, such as how much is left. Users can judge approximately how many more times it can be used and adjust the purchase time according to the remaining amount to ensure that users can use it continuously.

[0100] In some embodiments of the present invention, as described above, the functional fluid is continuously consumed as the user uses it. When it is depleted or about to be depleted, the user can choose to purchase a new functional nozzle 100. However, to save on purchase costs, a functional fluid refill port is provided on the main body 21, allowing the user to purchase a functional fluid refill kit and refill the functional fluid themselves. In other embodiments, in addition to refilling the functional fluid, the functional fluid storage component 2 can be disassembled and replaced with a new one to complete the replenishment. Therefore, the functional fluid storage component 2 is configured to be detachably connected to the housing 1.

[0101] In some embodiments of the present invention, there are various ways to achieve a detachable connection, such as threaded engagement, screw engagement, snap-fit ​​engagement, rotational engagement, magnetic engagement, etc. Specifically, it can be a direct detachable connection between the functional liquid storage component 2 and the housing 1, an indirect detachable connection between the functional liquid storage component 2 and the housing 1 via a direct detachable connection between the injection component 3 and the housing 1, or direct detachable connections between the functional liquid storage component 2 and the injection component 3 and the housing 1, respectively. The following description uses only the detachable connection between the functional liquid storage component 2 and the housing 1 as an example; other connection methods are within the scope of protection of this application. In one embodiment, the functional liquid storage component 2 and the housing 1 are connected by a snap-fit ​​detachable connection. Figures 1 to 3 As shown, the housing 1 includes a first part 14 and a second part 15, which are detachably connected. Both the first part 14 and the second part 15 are hollow. One end of the first part 14 is a suction port 11, and one end of the second part 15 is an air inlet 12. A gas channel 13 is formed between the suction port 11 and the air inlet 12. At least a portion of the injection component 3 and the functional liquid reservoir 2 are located within the second part 15. The detachable connection between the first part 14 and the second part 15 can be a threaded connection, a screw connection, a snap-fit ​​connection, or a rotational connection. In one embodiment, the first part 14 and the second part 15 are threadedly connected. Opposite forces are first applied to the first part 14 and the second part 15 to separate them, and then the functional liquid reservoir 2 is detached from the second part 15. Since at least a portion of the injection component 3 and the functional liquid reservoir 2 are located within the second part 15, a force application point is provided for the user, facilitating disassembly.

[0102] In some embodiments of the present invention, and in another embodiment, the housing 1 includes a body and a sliding cover. A window is provided on the body and is slidably connected to the sliding cover. The size of the window is greater than or equal to the sum of the sizes of the functional fluid reservoir 2 and the injection assembly 3. The user applies force to the sliding cover, causing it to slide relative to the body and exposing the window. The user can then remove the injection assembly 3 and the functional fluid reservoir 2 from the body through the window, and then insert a brand new injection assembly 3 and functional fluid reservoir 2 into the body through the window. Finally, the sliding cover is slid in the opposite direction to close the window, completing the replacement of the functional fluid reservoir 2.

[0103] In some embodiments of the present invention, in one embodiment, the sliding direction of the sliding cover relative to the body may be along the axial direction of the body.

[0104] In some embodiments of the present invention, and in another embodiment, the sliding direction of the sliding cover relative to the body can be the circumferential direction surrounding the body.

[0105] In some embodiments of the present invention, such as Figure 3and Figure 8 As shown, the functional liquid carrier 6 may have slight differences in size. To prevent the functional liquid carrier 6 from falling out during user inhalation after being inserted into the air inlet 12, a fixing member 8 is provided inside the air inlet 12. The fixing member 8 is designed to fix functional liquid carriers 6 of different sizes. The functional liquid carrier 6 is used to receive the outflowing functional liquid. The fixing member 8 can deform under the action of external force, and the elastic force of the deformation can clamp and fix the functional liquid carrier 6.

[0106] In some embodiments of the present invention, such as Figure 3 and Figure 8 As shown, in one embodiment, the fixing member 8 is an annular silicone member. The fixing force of the annular silicone member on the functional liquid carrier 6 is the same at all points, avoiding damage to the functional liquid carrier 6 caused by excessive fixing force in one direction.

[0107] In some embodiments of the present invention, such as Figure 3 and Figure 8 As shown, in one embodiment, the fixing member 8 includes multiple silicone fixing points, which are evenly spaced within the air inlet 12. The fixing force of the multiple silicone fixing points on the functional liquid carrier 6 is the same at all points, so as to avoid damage to the functional liquid carrier 6 caused by excessive fixing force in one direction.

[0108] In some embodiments of the present invention, such as Figure 3As shown, the functional mouthpiece 100 also includes a power supply component 4, a heating component 5, and a control component. The power supply component 4 and the heating component 5 are electrically connected to the control component, and the power supply component 4 is electrically connected to the heating component 5. The power supply component 4 is disposed within the housing 1, and the heating component 5 is disposed within the housing 1 and near the air inlet 12. The heating component 5 is configured to heat and atomize the functional liquid. The power supply component 4 and the heating component 5 work together to heat the outflowing functional liquid, atomizing it into mist. When the user inhales through the mouthpiece, the atomized functional liquid is inhaled along with the air, resulting in a better taste. Furthermore, the control component can control the heating temperature of the heating component, i.e., control the degree of atomization of the functional liquid. Different degrees of atomization affect the taste of the functional liquid, and the user can determine the heating temperature according to their preference, improving the user experience. Furthermore, the heating temperature range of the heating component 5 is 50℃-500℃, and even further, the heating temperature range of the heating component 5 is 50℃-350℃. After the functional liquid carrier 6 is inserted, the functional liquid flows onto it. The heating element 5 and power supply element 4 heat the functional liquid carrier 6, causing it to atomize and be inhaled by the user. To achieve better atomization, the heating element 5 works in conjunction with the functional liquid carrier 6. After the functional liquid is injected into the carrier 6, the heating element 5 heats and atomizes the carrier 6 and its contents, which are then ingested by the user through a gas channel. When the heating temperature is 250℃, this is equivalent to the heating temperature of an electronic cigarette. When the heating temperature is 350℃, the heating element 5 heats the functional liquid carrier 6 and its contents without burning, thus atomizing the liquid. In one embodiment, the functional liquid carrier 6 is a tobacco cartridge containing no e-liquid. The functional liquid storage unit 2 contains e-liquid. The functional liquid carrier 6 is inserted into the housing 1, triggering the injection assembly 3 to open in one direction, allowing the functional liquid to flow onto the functional liquid carrier 6. The heating element 5 is activated to heat the functional liquid carrier 6 and the functional liquid, atomizing the functional liquid for final use by the user. In another embodiment, the functional liquid carrier 6 is a tobacco cartridge containing e-liquid. The functional liquid storage unit 2 contains flavoring liquid. The functional liquid carrier 6 is inserted into the housing, triggering the injection assembly 3 to open in one direction, allowing the functional liquid to flow onto the functional liquid carrier 6. The heating element 5 is activated to heat the functional liquid carrier 6 and the functional liquid, atomizing the functional liquid for final use by the user.

[0109] In some embodiments of the present invention, the heating temperature varies for different types of functional liquids, and the control unit can achieve targeted heating and atomization according to the type of functional liquid.

[0110] In some embodiments of the present invention, the control element is a PID controller. The functional nozzle 100 also includes a temperature detection element connected to the housing 1. The temperature detection element is electrically connected to the control element, and the detection end of the temperature detection element is located inside the housing 1 and close to the heating element 5. The temperature detection element detects the real-time temperature of the heating element 5. When the real-time temperature reaches the target temperature, the PID controller controls the heating element 5 to stop heating. The PID controller is also used to compare the real-time temperature with the target temperature in real time. When the real-time temperature differs significantly from the target temperature, the PID controller controls the heating element 5 to restart, ensuring a constant temperature difference between the real-time temperature and the target temperature. This effectively avoids temperature fluctuations, achieves precise temperature control, and significantly improves the user experience.

[0111] In some embodiments of the present invention, the heating element 5 may be a heating wire or a heating plate. The heating element may be a resistance wire or graphene heating element.

[0112] In some embodiments of the present invention, a single heating element 5 may be provided, which is disposed within the housing 1 and near the air inlet 12. Alternatively, two or more heating elements 5 may be provided, spaced apart within the housing 1 and near the air inlet 12, thereby improving the user experience by heating the functional fluid in multiple stages.

[0113] In some embodiments of the present invention, the heating element 5 can be linear, sheet-shaped, or annular. In one embodiment, the heating element 5 is annular, because since the housing 1 has a hollow structure, setting the heating element 5 as annular better fits the shape of the housing 1.

[0114] In some embodiments of the present invention, the power supply component 4 can be a dry cell battery, such as a button cell, AAA battery, or AA battery. The power supply component 4 can also be a rechargeable battery, such as a lithium battery.

[0115] In some embodiments of the present invention, when a rechargeable battery is used, a charging interface 17 is provided on the housing 1 to facilitate charging. The charging interface 17 is electrically connected to the power supply component 4. The charging interface 17 can be a micro USB interface, a Lightning interface, or a Type / C interface.

[0116] In some embodiments of the present invention, as described above, since the heating element 5 is provided to heat and atomize the functional liquid, a heat insulation structure can be added to improve the user experience. Specifically, the functional nozzle 100 also includes a first heat insulation element disposed between the heating element 5 and the housing 1. The function of the first heat insulation element is, on the one hand, to minimize the transfer of heat to the surface of the housing 1 and prevent burns to the user, and on the other hand, to reduce heat loss and improve the heating and atomization effect. The first heat insulation element can be made of glass fiber, asbestos, rock wool, silicate, aerogel felt, vacuum plate, etc.

[0117] In some embodiments of the present invention, the functional nozzle 100 further includes a second heat insulation component, which is disposed between the heating element 5, the power supply element 4, and the control element to prevent the heat generated by the heating element 5 from affecting the performance of the power supply element 4 and the control element. The second heat insulation component can be made of glass fiber, asbestos, rock wool, silicate, aerogel felt, vacuum plate, etc.

[0118] In some embodiments of the present invention, when using the functional nozzle 100, the user inserts the functional liquid carrier 6 through the air inlet 12. After the functional liquid is injected, the heating element is activated to heat the functional liquid, causing it to atomize, and then the user inhales it. The heating element can be equipped with a start button on the housing, which connects the circuit to heat the functional liquid by pressing the start button. It can also be equipped with a temperature adjustment button, which adjusts the heating temperature of the heating element to achieve temperature changes within a certain range.

[0119] In some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the functional mouthpiece 100 also includes a memory, a processor, and a display screen 7. The memory is located inside the housing 1 and stores information about the functional liquid storage device 2, including its serial number, flavor, and dosage. The processor is also located inside the housing 1 and is electrically connected to both the memory and the power supply device 4 to collect and store information from the memory, the power supply device 4, and the functional liquid storage device 2. The display screen 7 is located on the housing 1 and is electrically connected to both the processor and the power supply device 4. The display screen 7 displays information and the power supply status of the power supply device 4. When the functional liquid storage device 2 is installed into the housing 1, the processor can display the information of the installed functional liquid storage device 2 on the display screen 7. The user can then see the information about the functional liquid storage device 2, such as its serial number, flavor, and dosage. As the user uses the device, the functional liquid is continuously consumed, and the user can clearly see the usage status. When the liquid is depleted or about to be depleted, the user is reminded to purchase a new functional mouthpiece 100.

[0120] In some embodiments of the present invention, one end of the housing 1 is a suction port 11, and the other end is an air inlet 12, forming a hollow structure. Small dust particles or foreign objects can easily enter the interior of the housing 1, affecting the injection assembly 3, power supply component 4, etc. Therefore, the functional suction nozzle 100 also includes a first cover, which is fastened to the suction port 11. The first cover can be made of a rigid material or a flexible material. In one embodiment, the first cover is made of a flexible material, which provides better sealing and can achieve waterproof and dustproof effects. Similarly, the functional suction nozzle 100 also includes a second cover, which is fastened to the air inlet 12. The second cover can be made of a rigid material or a flexible material. In one embodiment, the second cover is made of a flexible material, which provides better sealing and can achieve waterproof and dustproof effects, while also preventing foreign objects from entering and causing accidental triggering of the injection assembly 3.

[0121] In some embodiments of the present invention, and in other embodiments, the functional suction nozzle 100 further includes a shielding member rotatably connected to one end of the housing 1 near the air inlet 12. The shielding member is configured to block or open the air inlet 12. When the user uses the functional suction nozzle 100, the shielding member is rotated to open the air inlet 12, allowing the user to insert the functional liquid carrier 6 into the air inlet 12. When the functional suction nozzle 100 is not in use, the shielding member is rotated to close the air inlet 12, preventing foreign objects from entering and causing accidental triggering of the injection assembly 3.

[0122] In some embodiments of the present invention, such as Figure 3 and Figure 8 As shown, a limiting member 9 is provided inside the housing 1. The limiting member 9 is configured to limit the insertion depth of the functional liquid carrier 6 to prevent the functional liquid carrier 6 from being inserted too deeply and causing damage to the injection tube 31.

[0123] In some embodiments of the present invention, in one embodiment, the limiting member 9 is an annular protrusion inside the housing 1. The limiting member 9 and the housing 1 can be two independent parts connected by a detachable connection, or the limiting member 9 and the housing 1 can be an integral structure, which facilitates processing and manufacturing.

[0124] In some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the suction port 11 is flat, making the inlet smoother and improving user comfort.

[0125] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
