Description

A multi-airway nebulizer

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 15, 2023, with application number 202323083307.6 and invention name “A Multi-airway Nebulizer”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of atomization devices, and in particular to a multi-airway atomizer. Background Art

[0003] A nebulizer is a device that heats atomized liquid through an atomizer core to generate an aerosol. It typically consists of a liquid reservoir, an atomizer core, and an airway. The reservoir stores the atomized liquid, while the atomizer core heats the atomized liquid to generate an aerosol that flows out of the airway.

[0004] To sense airflow in the airway, a microphone is installed inside the airway. As the aerosol flows out of the airway, some of it forms condensation, which adheres to the inner wall of the airway and, after accumulating to a certain level, flows back along the airway. This condensation, when in contact with the microphone, can render it ineffective and prevent the atomizer coil from activating.

[0005] Summary of the Invention

[0006] In view of this, the purpose of the present application is to provide a multi-airway nebulizer to solve the problem that the microphone head in the existing nebulizer has the risk of failure due to contact with condensate.

[0007] To achieve the above technical objectives, the present application provides a multi-airway atomizer, comprising: a housing, a nozzle, an atomizing core, and a microphone;

[0008] The housing is provided with a first compartment and a second compartment separated from each other;

[0009] The housing is provided with an air inlet connected to the first compartment;

[0010] The atomizing core is disposed in the first compartment;

[0011] The microphone is arranged in the second compartment;

[0012] The suction nozzle is disposed on the shell and is connected to the first bin and the second bin.

[0013] Furthermore, the air inlet is located on a side of the first bin close to the suction nozzle.

[0014] Furthermore, oil-absorbing cotton is provided on a side of the first bin away from the suction nozzle.

[0015] Furthermore, the nozzle includes a central airway and side airways that are separated from each other;

[0016] The central airway is connected to the first chamber;

[0017] The side airway is connected to the second compartment.

[0018] Further, it also includes a control member;

[0019] A third compartment is also provided in the housing;

[0020] The third bin is arranged on a side away from the suction nozzle relative to the first bin;

[0021] The housing is provided with a connecting hole connecting the first compartment and the third compartment;

[0022] The control member is movably arranged in the shell and is used for controlling the opening and closing of the connecting hole.

[0023] Furthermore, the control member is rotatably disposed in the housing, and is used to rotate relative to the housing to cover or open the connecting hole.

[0024] Furthermore, the first end of the control member passes through the connecting hole and enters the first compartment;

[0025] The second end of the control member passes through the third compartment and extends outside the housing;

[0026] The control member is used for controlling the opening and closing of the connecting hole by sliding linearly relative to the housing.

[0027] Furthermore, an inserting groove is provided on the outer end surface of the shell;

[0028] The second end of the control member can be slidably extended into the insertion groove.

[0029] Furthermore, it also includes an elastic member;

[0030] Two ends of the elastic member respectively abut against the control member and the housing, and are used to provide elastic force to the control member to press the connecting hole.

[0031] Furthermore, it also includes a first sealing member;

[0032] The first sealing member is sleeved on the second end of the control member and seals the control member and the housing.

[0033] As can be seen from the above technical solution, the present application provides a multi-airway atomizer, comprising: a shell, a nozzle, an atomizing core and a microphone; a first chamber and a second chamber separated from each other are provided in the shell; an air inlet connected to the first chamber is provided on the shell; the atomizing core is provided in the first chamber; the microphone is provided in the second chamber; the nozzle is provided on the shell and connected to the first chamber and the second chamber.

[0034] In this solution, the atomizer core and the microphone are respectively arranged in the first and second compartments, thereby separating the microphone airway from the atomizer core airway. This prevents the condensate in the atomizer core from contacting the microphone, thus avoiding the risk of the microphone failing due to contact with the condensate.

[0043] 1 and 2 , a multi-airway atomizer provided in an embodiment of the present application includes: a housing 10 , a nozzle 20 , an atomizing core 30 and a microphone 40 .

[0044] The housing 10 is provided with a first chamber 11 and a second chamber 12 which are separated from each other. The housing 10 is provided with an air inlet 13 which is connected to the first chamber 11 ; the atomizing core 30 is provided in the first chamber 11 .

[0045] The microphone 40 is disposed in the second compartment 12 ; the nozzle 20 is disposed on the housing 10 and communicates with the first compartment 11 and the second compartment 12 .

[0046] Both the first chamber 11 and the second chamber 12 are provided with air outlets. The air inlet 13 is connected to the air outlet of the first chamber 11 to form an air passage for the atomizer core. The air outlet of the second chamber 12 serves as an air passage for the microphone. The microphone 40 can be activated by negative pressure in the microphone air passage. Therefore, the second chamber 12 can be a semi-enclosed cavity, or a through hole connected to the second chamber 12 can be provided on the housing 10 and used as the air inlet for the second chamber 12.

[0047] In this embodiment, the microphone 40 and the atomizer core 30 are respectively disposed in the second chamber 12 and the first chamber 11. Therefore, the aerosol generated in the first chamber 11 and the condensate formed by the aerosol will not come into contact with the microphone 40 in the second chamber 12. This can avoid the risk of the microphone 40 failing due to contact with the condensate, thereby increasing the service life of the microphone 40.

[0048] In other embodiments, the first compartment 11 and the second compartment 12 within the housing 10 are two detachable components connected by magnetism or snap fasteners. Once the second compartment 12 is detached, the microphone 40 and its airway are exposed to the outside world, allowing them to be cleaned. This added cleanability further enhances the reliability and durability of the device.

[0049] In a further improved embodiment, the air inlet 13 is located on a side of the first bin 11 close to the suction nozzle 20 .

[0050] Specifically, when the housing 10 is placed vertically, the nozzle 20 is generally located above the atomizer core 30. For ease of description, the embodiments provided in this application are also described as the housing 10 being placed vertically and the nozzle 20 being located above the atomizer core 30.

[0051] In this embodiment, the air inlet 13 is located on the side of the first chamber 11 near the nozzle 20, meaning that the air inlet 13 is connected to the top of the first chamber 11. In other words, the atomizer core airway draws air from the top of the first chamber 11. Since the atomizer core 30 uses bottom air intake, the gas in the atomizer core airway in this embodiment first flows from top to bottom in the first chamber 11 to the bottom of the atomizer core 30 before flowing out from the bottom to top within the atomizer core 30. This arrangement not only increases the airway length, ensuring ample air intake, but also prevents condensate flowing back from the first chamber 11 from clogging the air inlet 13.

[0052] Furthermore, oil-absorbing cotton 14 is provided on a side of the first bin 11 away from the suction nozzle 20 . That is, the oil-absorbing cotton 14 is provided at the bottom of the first bin 11 .

[0053] The oil-absorbing cotton 14 can absorb the refluxed condensate, thereby further improving the problem of the condensate flowing out of the air inlet 13 .

[0054] In one embodiment, the nozzle 20 includes a central air channel 21 and a side air channel 22 that are separated from each other; the central air channel 21 is connected to the first compartment 11 ; and the side air channel 22 is connected to the second compartment 12 .

[0055] The flow area of ​​the central airway 21 is larger than that of the side airway 22, ensuring that the atomizer core airway has sufficient flow space. The independent arrangement of the central airway 21 and the side airway 22 can effectively prevent the airflows of the two from mixing and causing the aerosol to flow into the second chamber 12.

[0056] Please refer to Figures 1 to 4. In other embodiments, the multi-airway nebulizer further includes a control component 50; a third chamber 15 is further provided in the shell 10; the third chamber 15 is provided on a side away from the mouthpiece 20 relative to the first chamber 11; a connecting hole 16 connecting the first chamber 11 and the third chamber 15 is provided on the shell 10; the control component 50 is movably provided in the shell 10 for controlling the opening and closing of the connecting hole 16.

[0057] The housing 10 may be provided with an intermediate seat 19 and a base 18. The intermediate seat 19 is mounted in the middle of the housing 10 and, together with the inner wall of the housing 10, forms a first compartment 11. Accordingly, the atomizer core 50 is mounted on the intermediate seat 19. The base 18 is mounted at the bottom of the housing 10 and, together with the inner wall of the housing 10 and the intermediate seat 19, forms a third compartment 15 for storing atomized liquid. A connecting hole 16 is provided on and through the intermediate seat 19, connecting the first compartment 11 with the third compartment 15.

[0058] When the nebulizer is not used for a long time, the control component 50 can close the connecting hole 16, so that the first chamber 11 and the third chamber 15 are separated from each other, so that the atomized liquid in the third chamber 15 cannot enter the first chamber 11 and seep out through the suction nozzle 20; when the nebulizer needs to be used, the connecting hole 16 can be opened by the control component 50 to connect the first chamber 11 and the third chamber 15, and then by turning the entire nebulizer over, etc., the atomized liquid in the third chamber 15 can flow into the first chamber 11 to soak the liquid-guiding cotton.

[0059] In actual use, some atomizer devices do not have a third chamber to prevent leakage of atomized liquid. However, this approach results in a smaller liquid storage capacity, necessitating the need to carry a separate liquid storage bottle when traveling. In this embodiment, the atomizer can control the connection and disconnection between the first chamber 11 and the third chamber 15 via a control element 50, eliminating the need for a separate liquid storage bottle. This provides advantages such as ease of operation, portability, and resistance to leakage and deterioration of the atomized liquid.

[0060] It should be noted that a battery compartment 110 may also be provided within the housing 10; within the battery compartment 110 is a battery module 80 electrically connected to the atomizer core 30. Furthermore, the battery cells and control components may be positioned between the battery module 80 and the atomizer core 30. The battery compartment 110 may be interconnected with the second compartment 12 or separated from the second compartment 12. The battery compartment 110 may be connected to the first compartment 11 and the second compartment 12 via magnetic attraction or snap-fit ​​connections, thereby forming a removable first compartment 11, second compartment 12, and battery compartment 110 within the housing 10.

[0061] In one embodiment, the control member 50 is linearly slidably disposed within the housing 10 and is configured to linearly slide relative to the housing 10 to cover or open the connection hole 16. When the control member 50 covers the connection hole 16, the control member 50 closes the connection hole 16.

[0062] In other words, the control member 50 opens or closes the connection hole by sliding linearly. The sliding direction of the control member 50 can be vertical, and a cover plate 51 can be connected to one end of the control member 50. By pulling or pressing the control member 50, the cover plate 51 can be moved to cover or move away from the connection hole 16, thereby controlling the opening and closing of the connection hole 16.

[0063] In a more specific embodiment, referring to FIG. 3 and FIG. 4 , a first end of the control member 50 passes through the connecting hole 16 and enters the first compartment 11 ; a second end of the control member passes through the third compartment 15 and extends out of the housing 10 .

[0064] In this embodiment, the connecting hole 16 can provide a guide for the sliding of the control member 50; correspondingly, the control member 50 is rod-shaped, and the connecting hole 16 can be an elongated hole.

[0065] The second end of the control member 50 extending out of the housing 10 is its bottom end; the control member 50 can be operated via the second end of the control member 50. The first end of the control member 50 enters the first compartment 11. Therefore, in this embodiment, when the connecting hole 16 is closed, the control member 50 covers the connecting hole 16 via the cover plate 51. When the connecting hole 16 needs to be opened, the connecting hole 16 can be opened by moving the control member 50 toward the suction nozzle 20, that is, by pressing the control member 50.

[0066] In a further improved embodiment, an inserting groove 17 is provided on the outer end surface of the housing 10 ; the second end of the control member 50 can be slidably inserted into the inserting groove 17 .

[0067] The insertion groove 17 allows the second end of the control member 50 to enter, and while providing a guide for the sliding of the control member 50, it can also prevent the bottom end of the control member 50 from protruding relative to the housing 10, making it inconvenient to place the housing 10.

[0068] Furthermore, a first sealing member 71 is included; the first sealing member 71 is sleeved on the second end of the control member 50 and seals the control member 50 and the housing 10 .

[0069] The first sealing member 71 can also be a silicone ring, which is used to ensure the sealing effect between the control member 50 and the housing 10 during the linear sliding process. Correspondingly, the first sealing member 71 can be fixedly disposed in the insertion groove 17.

[0070] Furthermore, a second sealing member 72 is provided on the end surface of the cover plate 51 facing the connection hole 16 ; the cover plate 51 is used to cover the connection hole 16 and seal the connection hole 16 through the second sealing member 72 .

[0071] The second sealing member 72 may be a silicone ring. When the cover plate 51 covers the connection hole 16 , the second sealing member 72 surrounds the connection hole 16 to seal and isolate the connection hole 16 from the first compartment 11 .

[0072] As an embodiment, the control member 50 can be connected to the shell 10 by snapping; specifically, the shell 10 can be provided with a first snap position and a second snap position; the control member 50 is provided with a snap, and during the linear sliding process of the control member 50, the snap can be driven to switch positions between the first snap position and the second snap position.

[0073] When the buckle is connected to the first buckle, the cover plate 51 is separated from the connection hole 16, so that the connection hole 16 is opened; when the buckle is connected to the second buckle, the cover plate 51 covers the connection hole 16, closing the connection hole 16.

[0074] In another embodiment, an elastic member 60 is further included; two ends of the elastic member 60 respectively abut against the control member 50 and the housing 10 , for providing an elastic force to the control member 50 to compress the connecting hole 16 .

[0075] When the control member 50 is pressed, the second end of the control member 50 squeezes the elastic member 30 to compress it, and at the same time pushes the cover plate 51 away from the connecting hole 16 to open the connecting hole 16; after the pressing force on the control member 50 is removed, the control member 50 can drive the cover plate 51 to move closer to the connecting hole 16 due to the restoring force of the elastic member 30 to seal and cover the connecting hole 16.

[0076] Correspondingly, the elastic member 30 may be disposed in the insertion groove 17 ; and a limiting plate for the elastic member 30 to abut against may be provided at the second end of the control member 50 .

[0077] In other embodiments, an injection channel may be provided inside the control member 50; the injection channel is connected to the outside of the shell 10; the control member 50 slides linearly along the shell 10 to control the injection channel to be connected or disconnected from the third chamber 15.

[0078] Specifically, the injection channel can be L-shaped, with its two ends respectively connected to the side of the control component 50 and the bottom of the control component 50; the control component 50 can control the injection channel to be connected or disconnected with the third chamber 15 by linear sliding.

[0079] In the reset state, the bottom end of the control member 50 can be flush with the bottom end of the shell 10. At this time, the liquid injection channel is separated from the third chamber 15, and the cover plate 51 closes the connecting hole 16; by pressing the control member 50, the connecting hole 16 can be opened and the liquid injection channel is connected to the third chamber 15. After that, the user can inject liquid into the third chamber 15 through the liquid injection channel. After that, the control member 50 is reset to separate the third chamber 15 from the liquid injection channel.

[0080] In another embodiment, a liquid injection plug 90 is further included; a liquid injection hole 111 communicating with the third chamber 15 is provided on the housing 10 ; and the liquid injection plug 90 is used to block the liquid injection hole 111 .

[0081] In this embodiment, the atomized liquid can be injected into the third chamber 15 through the liquid injection hole 111 , and then the liquid injection hole 15 is closed by the liquid injection plug 40 .

[0082] In practical applications, the control member 50 can also cover or open the connection hole 16 by rotating relative to the housing 10. That is, the control member 50 can be rotatably disposed in the housing 10.

[0083] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein.
