Referring to the drawings, the present application provides, in embodiments, a heat generating assembly 100 for use in a nebulizer, the heat generating assembly 100 heating a nebulized aerosol generating substrate upon energization to generate an aerosol.

Specifically, the atomizer has a liquid storage chamber. The reservoir is for receiving an aerosol-generating substrate. The heat generating component 100 is capable of receiving aerosol-generating substrate from the reservoir to heat the aerosol for aerosol generation. The atomizer also has an aerosol passage. The aerosol passage is in fluid communication with the heat generating component to output the generated aerosol to the outside through the aerosol passage.

Wherein, the liquid storage shell can be integrated with the outlet duct, also can split each other.

Specifically, the heat generating assembly 100 includes a heat generating top cover 10 and an atomizing core 20.

The heating top cover 10 is arranged in the shell. Specifically, the liquid storage chamber is located above the heat-generating top cover 10.

The atomizing core 20 is mounted on the air intake side of the heat generating top cover 10. It should be noted that, the air inlet side of the heat-generating top cover 10 refers to the side that receives the aerosol atomized from the atomizing core 20, and in the embodiment of the present application, the side of the heat-generating top cover 10 facing away from the liquid storage cavity is the air inlet side. A liquid outlet hole 11 is formed in one side, back to the air inlet side, of the heating top cover 10, and the liquid outlet hole 11 is communicated with the liquid storage cavity and the atomization core 20.

The air inlet side of the heating top cover 10 is provided with a containing groove 12, and the atomizing core 20 is contained in the containing groove 12. Wherein, the surface of one side of the atomizing core 20 facing the bottom of the accommodating groove 12 is a liquid absorption surface, the liquid absorption surface is communicated with the liquid outlet hole 11 and is used for absorbing aerosol generating matrixes to the atomizing core 20, the side of the atomizing core 20 facing away from the liquid absorption surface is an atomizing surface, and aerosol generated by heating and atomizing the atomizing core 20 is discharged from the atomizing surface.

In the embodiment of the present application, the heat generating component 100 further includes a heat generating seat 30, the heat generating top cover 10 is mounted on the heat generating seat, and the air inlet side is disposed toward the heat generating seat 30. An atomizing chamber is defined between the atomizing core 20 and the heat generating seat 30. Specifically, an atomization cavity is defined between the atomization surface and the heating seat 30.

The intake side is provided with an intake port 13 and a ventilation passage 14. The air inlet 13 is communicated with the atomizing core 20 and the aerosol channel, and is used for discharging aerosol generated by heating and atomizing the atomizing core 20 into the aerosol channel along with the airflow. The ventilation channel 14 is communicated with the atomization core 20 and the liquid storage cavity and used for balancing the pressure difference between the inside and the outside of the liquid storage cavity, so that the liquid storage cavity is convenient to discharge liquid.

The ventilation channel 14 comprises an air inlet end 141 communicating with the atomizing core 20, the air inlet end 141 being located on a different side of the atomizing core 20 than the air inlet 13. .

In the heat generating module 100 of the present application, the air inlet 13 and the air inlet end 141 of the ventilation duct 14 are provided on different sides of the atomizing core 20, so that the air inlet 13 and the ventilation duct 14 can be separated from each other. In this way, aerosol-generating substrate, condensate or other liquid in the ventilation channel 14 is less likely to enter the air inlet 13 and enter the aerosol channel, reducing pumping leakage.

In particular to the embodiment of the present application, the air inlet 13 is provided at a first side 21 of the atomizing core 20, and the air inlet end 141 of the ventilation channel 14 is provided at a second side 22 of the atomizing core 20, the first side 21 being adjacent to the second side 22.

In this way, the air intake port 13 and the ventilation duct 14 can be relatively isolated from each other in a limited space on the air intake side of the heat generation roof 10.

In other embodiments, the air intake end 141 of the ventilation channel 14 may also be disposed on a third side 23 of the atomizing core 20, the third side 23 being opposite the second side 22.

Specifically, the atomizing core 20 is rectangular, having long sides corresponding to the first side 21 and the third side 23 of the atomizing core 20, and short sides corresponding to the second side 22 of the atomizing core 20.

In other embodiments, if the atomizing core 20 has other polygonal structures, such as pentagons, the air inlet port 13 may be disposed on one side of the atomizing core 20, and the air inlet port 141 of the ventilation channel 14 may be disposed on the other side. If the atomizing core 20 is circular, the side of the atomizing core 20 where the air inlet 13 is located may be the side of the arc segment corresponding to the outer edge of the atomizing core 20, and the air inlet 141 of the ventilation channel 14 is disposed on the side of the other arc segment of the outer edge of the atomizing core 20.

In the embodiment of the present application, the ventilation channel 14 comprises a ventilation slot open on the slot wall of the receiving slot 12.

By arranging the ventilation slots in the accommodating slot 12, the atomizing core 20 is also accommodated in the accommodating slot 12, and the atomizing core 20 can block the ventilation slots to a certain extent, so that the difficulty of the aerosol generating substrate of the ventilation channel 14 entering the air inlet 13 and then entering the aerosol channel from the air inlet 13 is increased. In addition, since the ventilation groove is provided in the accommodating groove 12, the additional space of the heat-generating top cover 10 is not occupied, and the overall structure is simplified.

Optionally, the air intake end 141 of the ventilation channel 14 is disposed within the receiving slot 12. Thus, the air inlet end 141 of the ventilation channel 14 is separated from the air inlet 13 relatively more effectively.

In other embodiments, the ventilation channel 14 may not be provided in the accommodating groove 12, for example, but is not limited thereto.

In particular to the embodiments of the present application, at least part of the ventilation slots are provided on the side of the receiving slot 12 corresponding to the second side 22 of the atomizing core 20.

In some embodiments, the ventilation channel 14 further includes an air outlet end 142 in communication with the reservoir, the air outlet end 142 being disposed further from the air inlet 13 than the air inlet end 141.

Since the air outlet end 142 of the ventilation channel 14 is communicated with the liquid storage cavity, more aerosol atomized matrix in the liquid storage cavity can be accumulated at the air outlet end 142, and therefore, in the condition that the air inlet side area of the heating top cover 10 is limited, the air outlet end 142 is arranged further away from the air inlet 13, so that the aerosol generated matrix in the liquid storage cavity can be reduced more advantageously to enter the air inlet 13.

Specifically, the heat-generating top cover 10 has an outer peripheral side surrounding an air intake side, and the ventilation channel 14 extends from the air intake side where the air intake end 141 is located to the circumferential side, and then continues to extend from the circumferential side to a side of the heat-generating top cover 10 facing away from the air intake side until the air outlet end 142 communicates with the liquid outlet hole 11.

Further, the heat generating top cover 10 further has a buffer chamber 15, and the buffer chamber 15 forms part of the ventilation channel 14. Specifically, the buffer chamber 15 is provided on the circumferential side of the heat generating top cover 10.

In order to avoid that liquid such as aerosol-generating substrate, condensate or the like gathers at the air inlet end 141 of the ventilation channel 14 to influence the ventilation function of the ventilation channel 14 in advance, a buffer cavity 15 is arranged on the heating top cover 10 for collecting the liquid and preventing the liquid from entering the ventilation channel 14.

It should be noted that the buffer chamber 15 and the air inlet 13 are separated from each other. In this way, liquid such as aerosol-generating substrate, condensate or the like is prevented from entering the air inlet 13 from the buffer chamber 15.
