Technical Field

[0001] This utility model relates to the field of aerosol atomization technology, specifically to a nozzle assembly and an atomizing device. Background Technology

[0002] An electronic atomizing device is a device that converts an aerosol matrix into an aerosol through heating. Generally, an electronic atomizing device includes a reservoir for storing the aerosol matrix, an atomizing core that heats the aerosol matrix to generate an aerosol, a power supply mechanism, and a sensor switch to activate the atomizing core. However, even when not in use, the negative pressure chamber corresponding to the sensor switch may develop negative pressure due to changes in the external environment, causing the sensor switch to activate falsely. This not only leads to the unnecessary consumption of the aerosol matrix but also poses a safety hazard. Utility Model Content

[0003] The main technical problem this invention addresses is that in related technologies, inductive switches are prone to accidental activation, leading to unnecessary consumption of the aerosol matrix and posing safety hazards.

[0005] In one embodiment, the pressure relief channel includes a pressure relief hole and a drainage groove. The pressure relief hole is disposed through the isolation member along the air intake direction, and the drainage groove is disposed on the side of the isolation member away from the negative pressure chamber in the air intake direction. One end of the drainage groove is connected to the pressure relief hole, and the other end is connected to the main air passage.

[0006] In one embodiment, the air inlet end of the nozzle housing is provided with a plurality of notch structures communicating with the main air passage, and the plurality of notch structures are arranged at intervals around the main air passage; the drainage groove is connected to the main air passage through the notch structures.

[0007] In one embodiment, the nozzle assembly further includes a first liquid suction member located on the side of the isolation member away from the nozzle housing along the suction direction, and the first liquid suction member is configured to cover the openings of the pressure relief hole and the drainage groove.

[0008] In one embodiment, the nozzle assembly further includes a second liquid suction member, which is located on the side of the isolation member close to the nozzle housing along the suction direction; the second liquid suction member has a second through hole disposed opposite to the pressure relief hole, and the pressure relief hole communicates with the negative pressure chamber through the second through hole.

[0009] In one embodiment, the isolation member is provided with a guide channel and a liquid storage tank on the side near the negative pressure chamber. The guide channel extends in a direction from near the main air passage to away from the main air passage. The liquid storage tank is located at the end of the guide channel away from the main air passage and is in communication with the guide channel.

[0010] In one embodiment, the nozzle assembly further includes a sealing plug having an insert portion and a cover portion disposed opposite to each other. The insert portion is inserted into the main air passage, and the cover portion covers the sensing air outlet. A ventilation groove is provided on the surface of the cover portion opposite to the air outlet, and the ventilation groove connects the sensing air outlet to the outside.

[0011] Based on the same inventive concept, this application also provides an atomizing device, including a liquid storage component, an atomizing component, a control component, and the above-mentioned mouthpiece component;

[0012] The air inlet end of the suction nozzle assembly is fixedly disposed on the liquid storage assembly;

[0013] The liquid storage component has a liquid storage space inside, and the atomizing component is disposed in the liquid storage space;

[0014] The atomizing component has an atomizing channel, which is connected to the main air duct;

[0015] A control component is electrically connected to the atomizing component; the control component includes a sensor switch, which is used to control the operating state of the atomizing component.

[0016] In one embodiment, the liquid storage assembly includes a liquid storage shell and a liquid storage element, the liquid storage shell forming the liquid storage space, and the liquid storage element disposed within the liquid storage space; a first venting groove extending along the suction direction is provided between the side of the liquid storage element and the inner wall of the liquid storage shell, the first venting groove connecting the two ends of the liquid storage element in the suction direction; and / or, the liquid storage element further has a second venting groove inside, the second venting groove penetrating and connecting the two ends of the liquid storage element along the suction direction.

[0018] According to the above-mentioned nozzle assembly and atomizing device, the inductive switch is activated in response to the air pressure change in the negative pressure chamber. Since the negative pressure chamber is connected to the main airway, even if the negative pressure chamber experiences environmental changes (such as changes in air pressure caused by altitude, temperature, or acceleration), the negative pressure chamber will be balanced by the air pressure through the main airway, thereby avoiding the false activation of the inductive switch, preventing the unnecessary consumption of the aerosol matrix, and reducing safety hazards.

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

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

[0041] Atomizing devices generate aerosols by heating an aerosol matrix and mixing it with air. To facilitate control of the atomizer coil, atomizing devices typically include a sensor switch. This switch detects the negative pressure created by the user's inhalation and accordingly activates the coil. However, even when the atomizing device is not in use, changes in the external environment can create negative pressure at the sensor switch, causing it to erroneously activate the coil. This leads to unnecessary consumption of the aerosol matrix and increases safety hazards.

[0042] To prevent accidental activation of the atomizer coil and reduce safety hazards, this application provides a mouthpiece assembly, please refer to... Figure 1 and Figure 2 The suction nozzle assembly includes:

[0043] The nozzle housing 11 has an air inlet end 111 and an air outlet end 112. The interior of the nozzle housing 11 has a main air passage 113 that extends along the air intake direction. The air intake direction is from the air inlet end 111 toward the air outlet end 112.

[0044] The isolator 12 is fixedly disposed at the air inlet end 111 of the nozzle housing 11, and a negative pressure chamber 114 is formed between the isolator 12 and the nozzle housing 11. The negative pressure chamber 114 is connected to the mounting cavity 42 where the induction switch 41 is placed. The isolator 12 is also provided with a pressure relief channel 121, which connects the pressure chamber 114 and the main air passage 113.

[0045] The sensing air outlet 115 is located at the air outlet end 112 of the nozzle housing 11, and the sensing air outlet 115 is connected to the negative pressure chamber 114.

[0046] In this embodiment, the mouthpiece assembly 1 forms the mouthpiece in the atomizing device, allowing the user to inhale aerosol through a suction action. Simultaneously, the suction action itself generates negative pressure, triggering a pressure-sensing switch 41. The switch 41 then activates the atomizing assembly 3 in the atomizing device to heat the aerosol matrix, generating aerosol.

[0047] In this embodiment, to facilitate aerosol discharge, the nozzle assembly 1 includes a nozzle housing 11, and the nozzle housing 11 forms a main air passage 113. The main air passage 113 serves as the channel through which the aerosol flows. The main air passage 113 is connected to the atomizing component 3 in the atomizing device. The aerosol generated by the atomizing component 3 heating the aerosol matrix is ​​finally discharged outward through the main air passage 113. The main air passage 113 is relatively independent from other parts of the nozzle housing 11. This design helps prevent leakage of the aerosol matrix and facilitates the collection of condensate generated when the aerosol cools, preventing the condensate from flowing into other areas.

[0048] The nozzle housing 11 has an air inlet end 111 and an air outlet end 112, corresponding to the flow direction of the discharged aerosol, that is, along the inhalation direction, with the upstream end 111 and the downstream end 112. The nozzle assembly 1 also includes a separator 12, which is designed to cooperate with the nozzle housing 11, connecting and enclosing a negative pressure chamber 114. The negative pressure chamber 114 is a chamber connected to the mounting cavity 42. When a negative pressure is generated in the negative pressure chamber 114, the inductive switch 41 located in the mounting cavity 42 detects the negative pressure and accordingly controls the atomizing assembly 3 to heat the aerosol matrix to generate aerosol. To ensure that the aerosol discharge coincides with the activation of the induction switch 41, the nozzle housing 11 is provided with an induction outlet 115 that connects the negative pressure chamber 114 to the outside. The induction outlet 115 is located at the outlet end 112, so the induction outlet 115 is adjacent to the outlet of the main air channel 113. When using the device, the user can simultaneously draw in air from both the induction outlet 115 and the outlet of the main air channel 113. On the one hand, a negative pressure is generated in the negative pressure chamber 114. After triggering the induction switch 41, the induction switch 41 drives the atomizing component 3 to heat the aerosol matrix to generate aerosol, which is then discharged along the outlet of the main air channel 113.

[0049] To prevent the condensate in the main air duct 113 from flowing back and affecting the internal environment of the negative pressure chamber 114, or to prevent the condensate in the main air duct 113 from entering the mounting chamber 42 along the connection between the negative pressure chamber 114 and the mounting chamber 42 and contaminating the inductive switch 41, the negative pressure chamber 114 and the main air duct 113 are isolated from each other. That is, the negative pressure chamber 42 and the main air duct 113 are two independent spaces formed by the nozzle housing 11. The main air duct 113 is mainly used for the flow of aerosol during user suction, while the negative pressure chamber 114 is mainly used to generate negative pressure within the negative pressure chamber 114 during user suction, thereby triggering the inductive switch 41.

[0050] Under normal circumstances, one end of the negative pressure chamber 114 is connected to the outside through the sensing air outlet 115, and the other end is connected to the mounting cavity 42. The negative pressure chamber 114 itself is relatively closed. To prevent the negative pressure in the negative pressure chamber 114 from being generated due to changes in the external environment, such as pressure or temperature differences between the chamber and the outside, when the atomizing device is not in use, thus causing the sensing switch 41 to be falsely activated, the negative pressure chamber 114 in this embodiment is also connected to the main air channel 113 through a pressure relief channel 121. Since the negative pressure chamber 114 is connected to the main air channel 113, the space of the negative pressure chamber 114 is equivalent to adding extra space to the main air channel 113. When the pressure in the original space of the negative pressure chamber 114 changes, since the negative pressure chamber 114 is connected to the main air channel 113 through the pressure relief channel 121, the pressure relief channel 121 will automatically balance the air pressure in the negative pressure chamber 114, so that the pressure in the negative pressure chamber 114 will automatically return to the same state as the main air channel 113. If the atomizing device is not in use at this time, the induction switch 41 will not be accidentally activated, which effectively prevents the unnecessary consumption of aerosol matrix and reduces the safety hazards of the atomizing device.

[0051] If the atomizing device is in use, that is, when the user draws air into the nozzle assembly 1 along the air outlet 112, the negative pressure chamber 114 and the main air channel 113 will generate negative pressure at the same time, and the induction switch 41 can be triggered normally, thereby driving the atomizing assembly 3 to heat the aerosol matrix normally.

[0052] In this embodiment, the mounting cavity 42, which houses the inductive switch 41, can be directly installed in the mouthpiece assembly 1, essentially becoming part of the mouthpiece assembly 1. This method effectively moves the inductive switch 41 forward, shortening its trigger stroke, improving the trigger sensitivity of the atomizing device, and enhancing the initial inhalation experience. Alternatively, the mounting cavity 42 can also be located in other positions within the atomizing device, such as at the end of the liquid storage housing 21 furthest from the mouthpiece housing 11.

[0053] In some alternative embodiments, please refer to Figures 2 to 4To connect the negative pressure chamber 114 to the main air passage 113 and prevent aerosol condensate from accumulating in the pressure relief channel 121, the pressure relief channel 121 may specifically include a pressure relief hole 122 and a drainage groove 123. The pressure relief hole 122 is disposed through the isolator 12 along the suction direction, and the drainage groove 123 is disposed on the side of the isolator 12 away from the nozzle housing 11 in the suction direction. One end of the drainage groove 123 is connected to the pressure relief hole 122, and the other end is connected to the main air passage 113. In this embodiment, the isolator 12 and the negative pressure chamber 114 are connected by a pressure relief hole 122, and then the pressure relief hole 122 and the main air passage 113 are connected by a drainage groove 123. The drainage channel 123 is located on the side of the isolation member 12 away from the negative pressure chamber 114, which means that the drainage channel 123 is located away from the nozzle housing 11. Therefore, under normal circumstances, the drainage channel 123 cannot retain aerosol condensate and can remain in a connected state.

[0054] In some alternative embodiments, please refer to Figure 4 To further prevent aerosol condensate from clogging the pressure relief channel 121, the drainage channel 123 may also have at least a first channel segment and a second channel segment that are interconnected and intersect. In other words, the pressure relief channel 121 may have bends. This design ensures that a large amount of aerosol is not located in the pressure relief channel 121, thereby preventing aerosol condensate from clogging the pressure relief channel 121.

[0055] In some alternative embodiments, please refer to Figure 5 To connect the drainage channel 123 to the main air passage 113, the air inlet end 111 of the nozzle housing 11 is provided with multiple notch structures 116 connecting to the main air passage 113. These multiple notch structures 116 are arranged at intervals around the main air passage 113. The drainage channel 123 is connected to the main air passage 113 through these notch structures 116. The notch structures 116 on the air inlet end 111 of the nozzle housing 11 create a clearance, allowing the drainage channel 123 to pass through these notch structures 116 and directly connect to the main air passage 113. Since there are multiple notch structures 116, and each notch structure 116 is arranged around the main air passage 113, the drainage channel 123 can have various ends at different positions, all of which can pass through the corresponding notch structure 116 to connect to the main air passage 113.

[0056] In some alternative embodiments, please refer to Figure 6To seal the pressure relief hole 122 and the drainage channel 123, and to absorb aerosol condensate, the nozzle assembly 1 may further include a first suction element 13. The first suction element 13 is located on the side of the isolator 12 away from the nozzle housing 11 along the suction direction, and covers the openings of the pressure relief hole 122 and the drainage channel 123. Since the pressure relief hole 122 and the drainage channel 123 are open, the first suction element 13 can seal them. Simultaneously, the first suction element 13 can also absorb the aerosol matrix, including aerosol matrix leaked from the atomizing device, or aerosol condensate formed when aerosols condense upon cooling, preventing condensate from clogging the pressure relief channel 121. Furthermore, when aerosol condensate flows back into the main air passage 113, the aerosol condensate flows downward along the inner wall of the main air passage 113. During this flow, when the aerosol condensate passes through the notch structure 116, it can be absorbed by the first suction member 13 through the notch structure 116. Since multiple notch structures 116 are arranged around the main air passage 113, aerosol condensate flowing back in any direction in the main air passage 113 can be guided through the notch structure 116 at the corresponding position and then absorbed by the first suction member 13.

[0057] In some alternative embodiments, please continue to refer to Figure 6 To collect aerosol condensate located in the negative pressure chamber 114, the nozzle assembly 1 may further include a second suction member 14. The second suction member 14 is located on the side of the separator 12 near the nozzle housing 11 along the suction direction. The second suction member 14 has a second through hole opposite to the pressure relief hole 122, and the pressure relief hole 122 communicates with the negative pressure chamber 114 through the second through hole. The second suction member 14 is located on the side of the pressure relief hole 122 located in the negative pressure chamber 114. During use, aerosol may flow through the negative pressure chamber 114 and condense upon cooling to form aerosol condensate. By providing the second suction member 14, the aerosol condensate can be absorbed, preventing the aerosol condensate from filling the pressure relief hole 122 and further preventing the condensate from flowing through the pressure relief hole 122 into the drainage groove 123.

[0058] In some alternative embodiments, please refer to Figure 3To further collect aerosol condensate, the side of the isolator 12 near the negative pressure chamber 114 can also be provided with a guide channel 15 and a storage tank 16. The guide channel 15 extends along the direction from near the main air passage 113 to away from the main air passage 113; the storage tank 16 is located at the end of the guide channel 15 away from the main air passage 113 and is connected to the guide channel 15. The guide channel 15 can be configured as a flow channel with a vertical drop, which allows the aerosol condensate to flow along the vertical drop direction of the guide channel 15; and the storage tank 16 can be located at the lower part of the guide channel 15, so the aerosol condensate flowing along the guide channel 15 will collect in the storage tank 16.

[0059] The guide channel 15 is located inside the negative pressure chamber 114. Therefore, the guide channel 15 is mainly used to collect aerosol condensate in the negative pressure chamber 114, primarily to prevent aerosol condensate from clogging the mounting cavity 42 where the inductive switch 41 is located. Furthermore, to further prevent this, the opening of the mounting cavity 42 can be positioned higher than the storage tank 16. Therefore, the aerosol condensate collected in the storage tank 16 will be lower than the opening of the mounting cavity 42, thus preventing aerosol condensate from entering the opening of the mounting cavity 42 and contaminating the inductive switch 41.

[0060] In some alternative embodiments, please refer to Figure 7 and Figure 8 To facilitate production and transportation and prevent leakage of the aerosol matrix, the nozzle assembly 1 may further include a sealing plug 6. The sealing plug 6 has an insert portion 61 and a cover portion 62 disposed opposite to each other. The insert portion 61 is inserted into the main air channel 113, and the cover portion 62 is disposed over the sensing air outlet 115. A ventilation groove 63 is provided on the surface of the cover portion 62 opposite to the air outlet 112, connecting the sensing air outlet 115 to the outside. The sealing plug 6, connected to the air outlet 112 of the nozzle assembly 1, seals the main air channel 113 by being inserted into it, thereby preventing leakage of the aerosol matrix from the main air channel 113. The cover portion 62, covering the sensing air outlet 115, prevents external dust from entering the sensing air outlet 115. Furthermore, the cover 62 is provided with a ventilation groove 63, which connects the sensing air outlet 115 to the outside. Therefore, the sensing air outlet 115 can be normally connected to the outside. Its function is similar to that of the pressure relief channel 121. It can also prevent negative pressure from being generated in the negative pressure chamber 114 connected to the sensing air outlet 115, thereby preventing the induction switch 41 from being falsely activated.

[0061] According to the nozzle assembly 1 in this embodiment, since the negative pressure chamber 114 is connected to the main airway 113 through the pressure relief channel 121, even if the environment of the negative pressure chamber 114 changes, it will be automatically balanced through the main airway 113 without affecting the user's suction, thus avoiding the false activation of the induction switch 41 and preventing the unnecessary consumption of the aerosol matrix, reducing safety hazards. Furthermore, during transportation and storage, a sealing plug 6 is usually installed at the nozzle to prevent oil leakage from the atomizing device and to ensure the cleanliness of the nozzle and main airway. However, if the sealing plug 6 is completely sealed, the pressure in the negative pressure chamber 114 will also change due to the seal, potentially causing the induction switch 41 to activate falsely. Therefore, by providing an air exchange groove 63 on the surface of the sealing plug 6's covering portion 62 opposite to the air outlet 112, the air pressure between the negative pressure chamber 114 and the external environment can be balanced, preventing the false activation of the induction switch 41, thus preventing the unnecessary consumption of the aerosol matrix and reducing safety hazards.

[0062] In addition, this application embodiment also provides an atomizing device, please refer to... Figure 9 and Figure 10 The atomizing device includes a liquid storage component 2, an atomizing component 3, a control component, and a mouthpiece component 1 as described in this embodiment; wherein:

[0063] The air inlet 111 of the nozzle assembly 1 is fixedly disposed on the liquid storage assembly 2. The connection between the nozzle assembly 1 and the liquid storage assembly 2 can be detachable, which facilitates the maintenance of the components in the nozzle assembly 1, such as the treatment of the aerosol condensate collected in the isolation member 12, the first liquid suction member 13 and the second liquid suction member 14.

[0064] The liquid storage component 2 has a liquid storage space inside for storing the aerosol matrix. The atomizing component 3 is disposed in the liquid storage space. The atomizing component 3 can heat the aerosol matrix to generate aerosol.

[0065] The atomizing component 3 has an atomizing channel 31, which is connected to the main air channel 113; the atomizing component 3 also has a mechanism for storing aerosol matrix, and the atomizing component 3 can heat the aerosol matrix that enters it to generate aerosol.

[0066] A control component is electrically connected to the atomizing component 3. The control component includes a sensor switch 41, which controls the operating state of the atomizing component 3. The operating state of the atomizing component 3 is controlled by the sensor switch 41. That is, if the sensor switch 41 is triggered, it will drive the atomizing component 3 to heat the aerosol matrix to generate aerosol; if the sensor switch 41 is not triggered, the atomizing component 3 will not be in the operating state, and the atomizing device will not produce aerosol.

[0067] In some alternative embodiments, please refer to Figure 10 and Figure 11 To prevent the rapid and large-scale entry of the aerosol matrix into the atomizing component 3 while storing the aerosol matrix, the liquid storage component 2 specifically includes a liquid storage shell 21 and a liquid storage element 22. The liquid storage shell 21 forms a liquid storage space, and the liquid storage element 22 is disposed within the liquid storage space. A first exhaust groove 23 extending in the intake direction is formed between the side of the liquid storage element 22 and the inner wall of the liquid storage shell 21, connecting the two ends of the liquid storage element 22 in the intake direction. The liquid storage element 22 stores the aerosol matrix through capillary action, thus slowing the rate at which the aerosol matrix enters the atomizing component 3 from the liquid storage space, preventing a large amount of aerosol matrix from entering the atomizing component 3 in a short period. The first exhaust groove 23 formed between the liquid storage shell 21 and the liquid storage element 22 allows gas in the liquid storage element 22 to be discharged outwards, thereby making it easier for the aerosol matrix in the liquid storage element 22 to move to the location of the atomizing component 3 and preventing wicking.

[0068] In addition to forming a first venting groove 23 between the liquid storage component 22 and the liquid storage shell 21 to facilitate the discharge of air from the liquid storage component 22, the liquid storage component 22 in this embodiment may also have a second venting groove 24, wherein the second venting groove 24 extends through and connects to both ends of the liquid storage component 22 along the air intake direction. The purpose of the second venting groove 24 is similar to that of the first venting groove 23, both facilitating the discharge of air from the liquid storage component 22 and preventing blockage of the aerosol matrix.

[0069] In some alternative embodiments, please refer to Figure 12 The liquid storage component 2 can also be provided with a liquid injection hole 25 on the side of the nozzle component 1 along the suction direction. The liquid injection hole 25 is connected to the liquid storage space, and the aerosol matrix can be added into the liquid storage space through the liquid injection hole 25. The isolation member 12 is provided with a liquid injection plug 124 on the side of the isolation member 12 away from the nozzle housing 11 along the suction direction, that is, on the side of the isolation member 12 close to the liquid storage component 2 along the suction direction. The liquid injection plug 124 is inserted into the liquid injection hole 25 to block the liquid injection hole 25, so that the liquid storage space can be sealed without adding the aerosol matrix through the liquid injection hole 25, and the aerosol matrix can be prevented from leaking.

[0070] In addition, the atomizing device may also include a power supply component 5, which can provide power to the induction switch 41 and the atomizing component 3; the power supply component 5 can be a disposable battery or a rechargeable battery, and the power supply component 5 can also be detachably installed in the atomizing device for easy maintenance.

[0071] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
