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 pneumatic switch to trigger the atomizing core. In related technologies, the pneumatic switch is typically located in the middle or bottom area of ​​the atomizing device in the exhaust direction, relatively far from the mouthpiece. This results in a longer sensing airway for triggering the pneumatic switch, leading to lower sensitivity and consequently, insufficient initial vaping sensation. Utility Model Content

[0003] The main technical problem solved by this invention is the low sensitivity of the pneumatic switch and poor suction experience caused by the excessively long sensing air passage of the pneumatic switch in related technologies.

The liquid storage tank is located at the end of the guide groove away from the main air passage and is in communication with the guide groove.

[0010] In one embodiment, the sensing groove and the liquid storage groove are disposed opposite to each other on both sides of the isolation member along the air intake direction; a hollow connecting column is disposed in the liquid storage groove, and the connecting column extends along the height direction of the liquid storage groove; one end of the connecting column near the bottom of the liquid storage groove is connected to the sensing groove, and the other end of the connecting column away from the bottom of the groove is suspended in the liquid storage groove and connected to the sensing air passage.

[0014] In one embodiment, the housing assembly includes an outer shell and an inner shell, the outer shell covering the inner shell; the gap between the outer shell and the inner shell forms an atmospheric cavity, the atmospheric cavity being connected to the outside atmosphere, and the sensing slot being connected to the atmospheric cavity.

[0026] The present invention 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.

[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. 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.

[0028] 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).

[0029] In electronic atomizing devices, to facilitate convenient activation of the atomizer coil to heat the aerosol matrix in conjunction with the user's inhalation, related technologies typically employ a pneumatic switch to activate the coil. When the pneumatic switch detects the negative pressure generated by the user's inhalation, it drives the coil to heat the aerosol matrix. However, existing pneumatic switches are usually located in the middle or bottom of the atomizer, far from the mouthpiece. This considerable distance results in a long sensing airway for triggering the switch, leading to low sensitivity and affecting the initial inhalation experience.

[0030] To improve the inhalation experience of atomizing devices, this application provides an atomizing device. Please refer to [reference needed]. Figure 1 and Figure 2The atomizing device includes a nozzle assembly 1 and an atomizing assembly 2. The nozzle assembly 1 has a main airway 11, a negative pressure chamber 12, and a sensing groove 13. The nozzle assembly 1 has an air inlet end and an air outlet end arranged opposite to each other along the inhalation direction. The main airway 11 extends along the air inlet end and the air outlet end. The air outlet end of the nozzle assembly 1 is provided with a sensing air outlet 14 connected to the negative pressure chamber 12 and an atomizing air outlet 111 connected to the main airway 11. The sensing groove 13 is located on the side of the main airway 11 away from the sensing air outlet 14. A pneumatic switch 15 is provided in the sensing groove 13. The two sides of the pneumatic switch 15 are respectively connected to the negative pressure chamber 12 and the outside atmosphere. The end of the main airway 11 near the air inlet end is connected to the atomizing assembly 2.

[0031] The atomizing device in this embodiment includes at least two main components: a mouthpiece assembly 1 for discharging the aerosol matrix and for the user to inhale, and an atomizing assembly 2 for heating the aerosol matrix to generate aerosol. To dissipate the aerosol matrix, the mouthpiece assembly 1 is enclosed to form a main air passage 11, which communicates with the atomizing assembly 2. The aerosol generated by the atomizing assembly 2 heating the aerosol matrix can be discharged outwards through the main air passage 11. The main air passage 11 is arranged along the inlet and outlet ends of the mouthpiece assembly 1, with the inlet end positioned closer to the atomizing assembly 2 for communication between the main air passage 11 and the atomizing assembly 2, and the outlet end positioned further away from the atomizing assembly 2 for discharging the aerosol from the main air passage 11.

[0032] To coordinate with the user's suction action on nozzle assembly 1, the atomizing assembly 2 is directly triggered to heat the aerosol matrix to generate an aerosol. Please refer to [link / reference needed]. Figure 3 and Figure 4 In this embodiment, the nozzle assembly 1 also forms a negative pressure chamber 12 and a sensing groove 13. The negative pressure chamber 12 is connected to the outside through a sensing outlet 14, which is adjacent to the outlet of the main airway 11. When the user inhales through the nozzle assembly 1, a negative pressure is generated in the negative pressure chamber 12 through the sensing outlet 14, thereby triggering the pneumatic switch 15 in the sensing groove 13 connected to the negative pressure chamber 12. When the pneumatic switch 15 is triggered, the atomizing assembly 2 is correspondingly triggered to heat the aerosol matrix, generating aerosol, which is then discharged along the main airway 11 through the user's inhalation. In this embodiment, both the negative pressure chamber 12 and the sensing groove 13 are formed in the nozzle assembly 1, thus greatly shortening the distance from the sensing outlet 14 to the sensing groove 13, thereby improving the sensing sensitivity of the pneumatic switch 15 in the sensing groove 13 and improving the inhalation experience of the atomizing device.

[0033] The atomizing component 2 and the mouthpiece component 1 are fixedly connected. The atomizing component 2 has an atomizing core 21 that can heat the aerosol matrix in the working state, and an atomizing channel 22 that guides the flow of aerosol. The atomizing channel 22 is connected to the main air channel 11. In this way, the aerosol generated by heating the atomizing core 21 will be discharged outward along the direction of the atomizing channel 22-main air channel 11.

[0034] Since the sensing groove 13 is located in the nozzle assembly 1, the aerosol generated by the atomizing device will condense into droplets due to cooling as it is discharged outward along the main air duct 11. To prevent condensate from entering the sensing groove 13 and contaminating the pneumatic switch 15, affecting its sensitivity, or even causing direct damage, in some optional embodiments, the sensing groove 13 can be offset from the axial direction of the main air duct 11. Because the sensing groove 13 is offset from the axial direction of the main air duct 11, the condensate generated in the main air duct 11 will not enter the sensing groove 13 after recirculation, thus preventing the recirculated condensate from contaminating the pneumatic switch 15. The offset of the sensing groove 13 from the axial direction of the main air duct 11 means that the sensing groove 13 is located outside the straight line extending from the main air duct 11. This allows the aerosol condensate to flow back along the main air duct 11 but not into the sensing groove 13 chamber.

[0035] In some optional embodiments, to further prevent condensate from affecting the pneumatic switch 15, the sensing outlet 14 and the sensing groove 13 can be respectively disposed on both sides of the main air passage 11. The placement of the sensing outlet 14 and the sensing groove 13 on both sides of the main air passage 11 effectively increases the distance between them, thus keeping the pneumatic switch 15 away from the sensing outlet 14. This prevents condensate generated at the sensing outlet 14 from flowing into the sensing groove 13 and contaminating the pneumatic switch 15. The sensing outlet 14 and the sensing groove 13 are connected by a negative pressure chamber 12, which can be a chamber surrounding the main air passage 11, with a housing separating the main air passage 11 from the negative pressure chamber 12.

[0036] In some alternative embodiments, please refer to Figure 3 and Figure 4For ease of assembly, the nozzle assembly 1 in this embodiment can be formed by splicing two or more components. Specifically, the nozzle assembly 1 may include a nozzle housing 16 and an isolator 17 fixedly connected. The isolator 17 is fixedly disposed on the nozzle housing 16 at the air inlet end, and the isolator 17 and the nozzle housing 16 enclose a negative pressure chamber 12. A sensing groove 13 is formed on the isolator 17. The nozzle assembly 1 in this embodiment is formed by splicing the nozzle housing 16 and the isolator 17 together. The nozzle housing 16 itself encloses a main air passage 11, which is disposed inside the nozzle housing 16. The area between the inside of the nozzle housing 16 and the isolator 17, outside the main air passage 11, encloses a negative pressure chamber 12. The nozzle housing 16 is provided with a sensing air outlet 14 that connects the negative pressure chamber 12 to the outside. A sensing groove 13 is formed on the isolator 17, and a pneumatic switch 15 is disposed in the sensing groove 13. The sensing groove 13 is connected to the negative pressure chamber 12. The nozzle housing 16 and the isolator 17 can be made of different materials. The nozzle housing 16 can be made of materials such as hard plastic, and the isolator 17 can be made of materials with sealing properties such as silicone. In this way, when the nozzle housing 16 and the isolator 17 are assembled, the connection between the isolator 17 and the nozzle housing 16 can be well sealed, which can prevent air leakage or leakage of aerosol matrix.

[0037] In some alternative embodiments, please refer to Figure 4 In order to form the main air passage 11, the negative pressure chamber 12, and the sensing groove 13 on the nozzle housing 16, the nozzle housing 16 in this embodiment may specifically include a nozzle inner tube 161, a nozzle end face 162, and a nozzle outer shell 163, wherein the nozzle inner tube 161, the nozzle end face 162, the nozzle outer shell 163, and the separator 17 enclose and form the negative pressure chamber 12; the main air passage 11 is formed in the nozzle inner tube 161; the nozzle end face 162 connects the nozzle inner tube 161 and the nozzle outer shell 163, and the sensing air outlet 14 is opened on the nozzle end face 162. The inner tube 161 and the outer shell 163 of the nozzle are connected by the end face 162 of the nozzle, and the inner tube 161, the outer shell 163, and the end face 162 of the nozzle can be directly integrally formed. The inner tube 161 itself forms a tubular structure, and the main air passage 11 is formed inside it. The outer shell 163 is arranged around the outside of the inner tube 161. The gap between the inner tube 161, the outer shell 163, and the separator 17 forms a negative pressure chamber 12. The sensing air outlet 14 is set on the end face 162 of the nozzle. Therefore, the position of the sensing air outlet 14 is adjacent to the air outlet of the main air passage 11. When in use, the user's suction action is directly applied to the sensing air outlet 14 and the air outlet of the main air passage 11 at the same time, so that the pneumatic switch 15 and the aerosol generated by suction can be triggered at the same time.

[0038] In some alternative embodiments, please refer to Figure 5 and Figure 6 The distance between the sensing groove 13 and the main air passage 11 can be set to be greater than the distance between the sensing outlet 14 and the main air passage 11. This further increases the distance between the sensing groove 13 and the main air passage 11, preventing the condensate in the main air passage 11 from flowing back into the sensing groove 13. A sensing air passage is formed between the nozzle housing 163 and the isolator 17 to connect the sensing groove 13 and the negative pressure chamber 12. In order to connect the negative pressure chamber 12 and the sensing groove 13, and at the same time collect the backflowed aerosol condensate to prevent the aerosol condensate from entering the sensing groove 13 and contaminating the pneumatic switch 15, the isolator 17 can also be provided with a guide groove 171 and a liquid storage tank 172 on the side of the isolator 17 near the nozzle housing 16 along the suction direction. The guide groove 171 extends from near the main air passage 11 to away from the main air passage 11; the liquid storage tank 172 is located at the end of the guide groove 171 away from the main air passage 11 and is connected to the guide groove 171. The guide channel 171 gradually decreases in height along the direction from the main air passage 11 away from it, allowing the condensate to flow along its slope and then converge into the storage tank 172. One guide channel 171 or multiple guide channels 171 can be provided, each independently guiding the aerosol condensate into the storage tank 172. The isolator has a guide channel 171 and a storage tank 172 on the side of the nozzle housing along the suction direction. The guide channel 171 extends from the periphery of the main air passage 11 to the sensing channel 13 to form a sensing air passage. The storage tank 172 is located at the end of the guide channel 171 away from the main air passage 11 and is connected to the guide channel 171. By setting a guide channel 171 to connect the negative pressure chamber 11 and the sensing channel 13 to form a sensing airway, it can sense the user's suction action and transmit negative pressure; the guide channel 171 is also connected to the liquid storage tank 172, so that the aerosol condensate in the guide channel 171 can flow into the liquid storage tank 172, which can avoid the residual aerosol condensate in the guide channel 171 from affecting the connection between the negative pressure chamber 11 and the sensing channel 13.

[0039] In some optional embodiments, in order to prevent condensate from entering the sensing tank 13, the sensing tank 13 and the liquid storage tank 172 are arranged opposite to each other on both sides of the isolation member 17 along the suction direction; a hollow connecting column 173 is provided in the liquid storage tank 172, and the connecting column 173 extends along the height direction of the liquid storage tank 172; one end of the connecting column 173 near the bottom of the liquid storage tank 172 is connected to the sensing tank 13, and the other end of the connecting column 173 away from the bottom of the tank is suspended in the liquid storage tank 172 and connected to the sensing air passage. In this embodiment, the sensing tank 13 and the storage tank 172 are arranged opposite to each other. The storage tank 172 can collect condensate not only through the guide channel 171 but also condensate above the sensing tank 13, thus preventing condensate from entering the sensing tank 13. Furthermore, in this embodiment, the storage tank 172 is provided with a hollow connecting column 173, which extends upwards from the bottom of the storage tank 172. The hollow design of the connecting column 173 allows it to connect the negative pressure chamber 12 and the sensing tank 13. The fact that the connecting column 173 is positioned above the bottom of the storage tank 172 prevents condensate in the storage tank 172 from entering the sensing tank 13 through the hollow structure of the connecting column 173, thus effectively protecting the pneumatic switch 15 and preventing it from being contaminated by condensate. Furthermore, one end of the hollow connecting column 173 is suspended in the liquid storage tank 172, so the liquid storage tank 172 can normally store aerosol condensate up to below the suspension opening of the connecting column 173 without affecting the connection between the connecting column 173 and the sensing airway.

[0040] In some alternative embodiments, in order to absorb the aerosol condensate in the negative pressure chamber 12, the nozzle assembly 1 may further include a second liquid suction member 19. The isolator 17 has a mounting groove 174 formed on the side of the nozzle housing 16 along the suction direction. The second liquid suction member 19 is disposed in the mounting groove 174 and is disposed opposite to the sensing air outlet 14. The guide groove 171 is located near the end of the main air passage 11 and is disposed higher than the second liquid suction member 19. If the condensate in the negative pressure chamber 12 is not treated, it may flow into the sensing groove 13, contaminating the pneumatic switch 15. Therefore, the suction nozzle assembly 1 in this embodiment may also include a second suction member 19, which is disposed in the negative pressure chamber 12, that is, on the side of the isolation member 17 near the suction nozzle housing 16, opposite to the sensing outlet 14. In this way, the aerosol condensate will be absorbed by the second suction member 19 during the backflow along the inner wall of the negative pressure chamber 12, thereby preventing it from entering the sensing groove 13 through the connection between the negative pressure chamber 12 and the sensing groove 13. Moreover, in order to further prevent the excessive condensate in the negative pressure chamber 12 from entering the sensing groove 13 through the sensing air passage when the second suction member 19 absorbs too much condensate, the opening of the guide groove 171 is higher than that of the second suction member 19. This allows the excess condensate not to enter the sensing groove 13 through the guide groove 171 when the second suction member is saturated with condensate. Figure 4 As shown.

[0041] In some alternative embodiments, please refer to Figure 4 and Figure 5 To absorb the aerosol condensate in the main air duct 11, the nozzle assembly 1 may further include a first liquid-absorbing element 18. The first liquid-absorbing element 18 is located on the side of the separator 17 away from the nozzle housing 16 along the air intake direction. The first liquid-absorbing element 18 surrounds the main air duct 11 and is connected to the main air duct 11. Since the first liquid-absorbing element 18 surrounds the main air duct 11 and is connected to the main air duct 11, when the aerosol in the main air duct 11 condenses into liquid upon cooling, it will flow downward along the inner wall of the main air duct 11. During the flow, it will pass through the first liquid-absorbing element 18 connected to the main air duct 11 and be absorbed by the first liquid-absorbing element 18, which can prevent the condensate from continuing to flow back downward into the atomizing assembly 2.

[0042] In some alternative embodiments, please refer to Figure 2 and Figure 7 To store and heat the aerosol matrix, the atomizing component 2 may further include a housing component 23 and a liquid storage component 24. The housing component 23 forms a liquid storage space, and the liquid storage component 24 is disposed within the liquid storage space. The liquid storage component 24 is provided with an assembly channel 25, and the atomizing core 21 is embedded in the assembly channel 25, forming an atomization channel 22 within the assembly channel 25. The liquid storage component 24 can absorb and transport the aerosol matrix through capillary action. The assembly channel 25 formed by the liquid storage component 24 is used to accommodate the atomizing core 21. The working state of the atomizing core 21 is linked to the pneumatic switch 15. When the pneumatic switch 15 is triggered, the pneumatic switch 15 controls the atomizing core 21 to heat the aerosol matrix to generate aerosol. The assembly channel 25 provided in the liquid storage component 24 forms an atomization channel 22 required for discharging aerosols. This atomization channel 22 is connected to the main air channel 11 so that the aerosols can be discharged outward along the outlet of the main air channel 11.

[0043] The working principle of the pneumatic switch 15 is to detect the voltage change on both sides. When the difference between the air pressure on one side of the negative pressure chamber 12 and the air pressure on the other side of the atmospheric chamber 233 reaches or exceeds a preset value, the pneumatic switch 15 is considered to be triggered. In order to generate an air pressure difference on both sides of the pneumatic switch 15, the negative pressure chamber 12 on one side is used to detect the user's suction action to generate negative pressure, that is, to reduce the air pressure, while the atmospheric chamber 233 on the other side is connected to the atmosphere and always maintains atmospheric pressure. Therefore, the reduction of air pressure on the negative pressure chamber 12 will generate a pressure difference with the air pressure on the atmospheric chamber 233. Specifically, in order to form the atmospheric chamber 233, the housing assembly 23 in this embodiment may include an outer shell 231 and an inner shell 232. The outer shell 231 is disposed over the inner shell 232. The gap between the outer shell 231 and the inner shell 232 forms the atmospheric chamber 233, which is connected to the outside atmosphere. The sensing groove 13 is connected to the atmospheric chamber 233. Since the atmospheric cavity 233 is connected to the outside atmosphere, the pressure on one side of the atmospheric cavity 233 remains constant at the atmospheric pressure of the current environment, while on the negative pressure cavity 12, when the user's suction assembly 1 performs suction, a negative pressure is generated within the negative pressure cavity 12 due to the user's suction action. This creates a pressure difference on both sides of the pneumatic switch 15. When the pressure difference reaches the trigger condition, the pneumatic switch 15 is triggered, thereby driving the atomizing assembly 2 to heat the aerosol matrix. In other words, in this embodiment, the pneumatic switch 15 isolates the negative pressure cavity 12 and the atmospheric cavity 233 from each other, preventing them from communicating.

[0044] According to the atomizing device in this application embodiment, since the sensing groove 13 and the pneumatic switch 15 are directly integrated into the mouthpiece assembly 1, the length of the sensing airway is greatly shortened, which greatly improves the sensing sensitivity of the pneumatic switch 15, thereby improving the initial inhalation experience.

[0045] 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 to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
