Referring to figures 1, 2 and 3, the present application provides an atomising device comprising a battery and a dual air duct atomiser 1, the battery being electrically connected to the atomiser 1 and being arranged to power the atomiser 1 so that an aerosol-generating substrate located within the atomiser 1 can be heated and atomised to form an aerosol.

Referring to fig. 4, 5, 6 and 7, the atomizer 1 with dual air passages includes a housing assembly 10, a base 20, a microphone 30, a central tube 40, a heating element 50 and a control panel, wherein the base 20, the control panel and the heating element 50 are all connected to the housing assembly 10, and the microphone 30 and the central tube 40 are all connected to the base 20.

Referring to fig. 8, 9 and 10, the housing assembly 10 includes an outer housing 12 and an inner housing 13 disposed in the outer housing 12, the outer housing 12 defines an air inlet 1212 and an air outlet 1232, a sidewall of the inner housing 13 defines an air inlet 132, and an outer surface of the inner housing 13 and an inner surface of the outer housing 12 define an air outlet channel 14. The base 20 includes a first base 23 and a second base 24, the first base 23 is disposed in the inner casing 13 and has a first end far away from the air outlet 1232, the first end is provided with a first through hole 232, the second base 24 is coupled to the first end and is provided with a second through hole 242, and the base 20 further has a first main air channel 22 penetrating through the first base 23 and the second base 24. The microphone 30 is disposed in the second through hole 242 and electrically connected to the control board. The central tube 40 is coupled to the base 20 and passes through the inner casing 13, and a second main air passage 41 is defined by an inner wall of the central tube 40. The second through hole 242, the first through hole 232, the air inlet 132, the air outlet channel 14 and the air outlet 1232 are sequentially communicated to form the auxiliary air channel 80, and the first main air channel 22, the second main air channel 41 and the air outlet 1232 are sequentially communicated to form the main air channel 70 independent from the auxiliary air channel 80. The heating element 50 is electrically connected to the control board and the battery.

The auxiliary airway 80 and the main airway 70 share the same inlet 1212 and the same outlet 1232. During operation, a user inhales air, external air flows to the microphone 30 through the air inlet 1212, and the air at the microphone 30 flows out to the outside of the atomizing device through the second through hole 242, the first through hole 232, the air inlet 132, the air outlet channel 14, and the air outlet 1232 in sequence (as indicated by the straight arrow in fig. 6), so that the air pressure at the microphone 30 may change. Further, the microphone 30 feeds back a signal to the control board, and the control board controls the battery to start up to supply power to the heating element 50. The heating element 50 heats the aerosol-generating substrate located within the inner shell 13 and atomises the aerosol-generating substrate to form an aerosol. The generated aerosol is then mixed with the external airflow flowing from the air inlet 1212 into the secondary main air passage 41 through the primary main air passage 22 and flows out from the air outlet 1232 to the outside for the user to inhale (as indicated by the straight arrow in fig. 5).

In the prior art, since the auxiliary air passage 80 of the microphone 30 is arranged to communicate with the air outlet 1232 via the main air passage 70, when the main air passage 70 is blocked by the aerosol-generating substrate, the air at the microphone 30 cannot be discharged via the main air passage 70, and the microphone 30 cannot be started, resulting in failure of suction.

In the present application, since the main airway 70 and the auxiliary airway 80 provided with the microphone 30 are independent of each other, even if the main airway 70 is blocked, the gas at the microphone 30 can be discharged through the auxiliary airway 80, so that the microphone 30 can be normally started, thereby facilitating the improvement of the reliability of the atomization device and the suction of the atomizer 1 with the dual airways thereof.

Referring to fig. 4 again, specifically, the outer shell 12 and the inner shell 13 both extend along a first direction (the direction indicated by the arrow a in fig. 4), and the outer shell 12 has a receiving cavity 1214. The outer shell 12 comprises a shell 121 and a suction nozzle 123, the shell 121 and the suction nozzle 123 are detachably abutted to form the outer shell 12 along a first direction, and the shell 121 and the suction nozzle 123 are sealed by a sealing gasket 60 arranged on the inner shell 13. The two ends of the housing 121 away from the suction nozzle 123 are respectively provided with an air inlet 1212 and an air outlet 1232 which are communicated with the accommodating chamber 1214. The inner housing 13 is a hollow structure with an open end and a closed end, the inner housing 13 is disposed in the accommodating chamber 1214, the open end of the inner housing 13 is tightly fit with the base 20, and the closed end of the inner housing 13 is disposed adjacent to the air outlet 1232 relative to the open end thereof. The inner shell 13 is for storing an aerosol-generating substrate. The heating element 50 and the center tube 40 are both disposed in the inner case 13, and the center tube 40 penetrates the closed end of the inner case 13 in the first direction. The side wall of the central tube 40 is further opened with an atomizing hole 42 communicating between the inside of the inner casing 13 and the second main air passage 41.

When the microphone is activated, the airflow at the microphone 30 may sequentially flow out to the outside through the second through hole 242, the first through hole 232, the air inlet hole 132, the air outlet channel 14, the accommodating cavity 1214 and the air outlet 1232, so that the air pressure at the microphone 30 is changed. Further, the microphone 30 feeds back a signal to the control board, the control board controls the battery to supply power to the heating element 50, and the heating element 50 heats the aerosol generating substrate in the inner shell 13 and atomizes the aerosol. Then, the aerosol enters the central tube 40 through the atomizing holes 42, mixes with the external air flow flowing in from the air inlet 1212, and then flows out through the accommodating cavity 1214 and the air outlet 1232 in sequence, and is inhaled by the user. The air outlet passage 14 and the air inlet hole 132 are designed to fully utilize the space inside the housing 12 so that the main air passage 70 and the auxiliary air passage 80 do not interfere with each other. With this design, the compactness of the internal spatial layout of the atomizer 1 can be improved, thereby facilitating the miniaturization of the atomizer 1.

Referring to fig. 7 again, further, the outer surface of the inner casing 13 is recessed to form an auxiliary groove 134, and the auxiliary groove 134 extends from the outlet of the air inlet hole 132 to the end surface of the inner casing 13 facing the air outlet 1232 along the first direction. The inner wall of the housing 12 and the wall of the auxiliary groove 134 define the air outlet passage 14. With this design, the air outlet channel 14 can guide the air flow so that the air flow can flow out of the housing 121 quickly. Thus, the microphone 30 can react quickly, so that the nebulizer 1 can be started quickly.

Referring to fig. 1 and 9 again, preferably, the second seat 24 is formed with a protrusion 244, the second through hole 242 penetrates the protrusion 244, and the protrusion 244 is inserted into the first through hole 232 and tightly sealed with the hole wall of the first through hole 232. In this way, the air is prevented from leaking out, so that the air at the microphone 30 can flow out only along the auxiliary airway 80. In addition, the protrusion 244 is inserted into the first through hole 232 and tightly fitted with the hole wall of the first through hole 232, so that the first seat 23 and the second seat 24 can be detachably connected.

Preferably, the number of the first through holes 232, the number of the second through holes 242, and the number of the protrusions 244 are two, the two first through holes 232 are axially symmetrically arranged and communicated with respect to the central axis of the atomizer 1, and the two second through holes 242 are axially symmetrically arranged with respect to the central axis of the atomizer 1, are in one-to-one correspondence with the two first through holes 232, and are in one-to-one correspondence with the two protrusions 244. That is, the two protrusions 244 are also disposed in an axisymmetric manner about the central axis of the atomizer 1, and on the same side of the central axis of the atomizer 1, the protrusions 244 and the second through holes 242 correspond to the first through holes 232 on the same side, the second through holes 242 penetrate through the corresponding protrusions 244, and the protrusions 244 are inserted into the corresponding first through holes 232. It is worth mentioning that, in this embodiment, there is only one air intake hole 132, and the air intake hole 132 communicates with any one of the first through holes 232.

Under the design, on one hand, when the second seat 24 is normally installed (0 degree) or reversely installed (rotated 180 degrees relative to the normal installation) relative to the first seat 23, the connection between the second seat 24 and the first seat 23 can be realized. On the other hand, when the microphone 30 is placed in any one of the second through holes 242, the air in the microphone 30 may sequentially flow into the air inlet hole 132 through the second through hole 242 where the microphone is placed and the first through hole 232 corresponding to the second through hole 242, or may sequentially flow into the air inlet hole 132 through the second through hole 242 where the microphone is placed, the first through hole 232 corresponding to the second through hole 242, and the other first through hole 232 communicating with the first through hole 232. Therefore, the rapid assembly of the second seat 24 and the microphone 30 is realized, and the second seat 24 and the first seat 23, and the microphone 30 and the second seat 24 can be prevented from being assembled in a wrong way.

Referring to fig. 6 and 9, further, each first through hole 232 includes a first segment 2321 and a second segment 2323, each first segment 2321 extends along a first direction, each second segment 2323 penetrates through the hole wall of the first segment 2321 along a second direction (e.g., a direction indicated by an arrow b in fig. 4) perpendicular to the first direction, each second through hole 242 penetrates through the second base 24 along the first direction and is communicated with the corresponding first segment 2321, and the second segment 2323 is aligned with and communicated with the air inlet hole 132 in the second direction. The first main air duct 22 is located at the center of the base 20 and penetrates the second seat 24 and the first seat 23 along the first direction. With this design, the second auxiliary air duct 21 can guide the air at the microphone 30 to one side of the base 20 and communicate with the air inlet hole 132 on the side wall of the housing assembly 10, and the main air duct 70 is located at the center of the base 20 relative to the auxiliary air duct 80. In this way, the main air passage 70 and the auxiliary air passage 80 can be provided independently without increasing the volume of the nebulizer 1, thereby improving the pumping reliability of the nebulizer 1.

Further, the outer surface of the first seat 23 is recessed to form a communication groove 234 extending in the second direction, and the outlets of all the second segments 2323 are located in the communication groove 234 and are communicated through the communication groove 234. That is, when the microphone 30 is fitted into one of the second through holes 242 and the air inlet hole 132 is communicated with the first through hole 232 not corresponding to the second through hole 242, the air at the microphone 30 can flow into the air inlet hole 132 through the corresponding second through hole 242, the first through hole 232 corresponding to the second through hole 242, the communication groove 234 and the other first through hole 232. The communication groove 234 can reduce the communication difficulty of the two first through holes 232, so that the atomizer 1 has lower manufacturing difficulty.

In one embodiment, the first seat 23 has a second end opposite to the first end, and the second end and the second seat 24 are both sealed with the inner wall of the inner housing 13. Thus, in the first direction, the communication groove 234 can be sealed between the second end and the second seat 24, and in the second direction, the inner wall of the inner housing 13 can cover the notch of the communication groove 234. Therefore, the gas flowing into the communication groove 234 can be prevented from being diffused to other spaces of the inner case 13, thereby ensuring that the gas can flow only into the gas inlet hole 132. Therefore, the atomizer 1 provided by the present application has superior pumping reliability.

Referring to fig. 10 again, the base 20 further includes an annular sealing strip 25, and the sealing strip 25 is sleeved on the second end and used for sealing a gap between the second end and the inner shell 13. Further, the second housing 24 is configured with a resilient structure 246, and the resilient structure 246 is used for sealing the gap between the second housing 24 and the inner shell 13. By the arrangement of the elastic structure 246 and the sealing strip 25, the gas flowing into the communication groove 234 is prevented from leaking out in the first direction, thereby ensuring that the gas can only flow out through the gas inlet hole 132. It is worth mentioning that the aerosol-generating substrate is mainly housed in the space in the inner shell 13 above the first seat 23, whereas no aerosol-generating substrate is present between the resilient structure 246 and the sealing strip 25. And the provision of the resilient structure 246 with the sealing strip 25 also prevents the aerosol-generating substrate in the inner shell 13 from flowing into the communicating channel 234.

Alternatively, the second fastening structure 24 can be a resilient fastening structure itself, and the resilient structure 246 can be integrally formed with other portions of the second fastening structure 24. Alternatively, other portions of second fastening structure 24 are rigid bases, and elastic structure 246 is formed by bonding or other connection methods with other portions of second fastening structure 24.

Above-mentioned atomizer and atomizer 1 of two air flues thereof, during the user's suction, the gas of miaow head 30 department can flow out through supplementary air flue 80, and then makes the atmospheric pressure of miaow head 30 department can change. In the application, since the auxiliary airway 80 where the microphone 30 is located is independent from the main airway 70, the microphone 30 can be activated even if the main airway 70 is blocked, thereby improving the pumping reliability of the atomizer device and the atomizer 1 with the dual airway.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
