Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating device, in particular to a condensate collecting structure of an aerosol generating device. BACKGROUND

[0002] The aerosol generating device can heat and atomize the aerosol generating substrate to generate aerosol for a user to inhale. When the aerosol generating device is working, the aerosol generating substrate is heated by an electric heating element to generate aerosol. Since the aerosol cannot be inhaled completely, especially when a rod-shaped aerosol generating substrate is used, aerosol can still be generated by the aerosol generating rod under the action of residual heat even if it is not inhaled. After stopping inhaling, the high-temperature aerosol is easy to diffuse to the gas channel and condense into condensate when meeting the cold wall, which is easy to leak outward, reducing the user experience.

Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0042] The serial numbers assigned to components herein, such as "first" and "second," are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" in this application, unless otherwise specified, include direct, indirect, and contact connections (couplings).

[0043] In one embodiment, the aerosol generating device includes a power supply, a heating element for heating the aerosol generating rod, and a condensate collecting assembly, wherein the power supply supplies power to the heating element. Figures 1 to 5 The condensate collection assembly includes an airway assembly 1 and a condensate collection structure 2. The airway assembly 1 has a housing chamber 11 and a gas passage 12. The housing chamber 11 has an insertion port 111 for inserting the aerosol generating stick 3 and an air inlet 112 for allowing gas to enter when the aerosol generating stick 3 is inhaled. The gas passage 12 is connected to the air inlet 112 so that when the aerosol generating stick 3 is inhaled, gas can enter the aerosol generating stick 3 in the housing chamber 11 through the gas passage 12.

[0044] In one embodiment, please refer to Figures 1 to 3 The aerosol generating stick 3 has a nozzle end 31 at one end and an air inlet end 32 at the other end. The nozzle end 31 has a nozzle for suction, and the air inlet end 32 is used to supply gas to the aerosol generating stick when the aerosol generating stick is sucked. In one embodiment, the aerosol generating stick 3 contains aerosol filaments or aerosol sheets for generating aerosol, and the nozzle of the aerosol generating stick contains a filter.

[0045] Please refer to Figure 3 The condensate collecting structure 2 has a liquid collecting channel 21 and a liquid storage cavity 22. The inlet 211 of the liquid collecting channel 21 is in communication with the gas channel 12, so that the condensate in the gas channel 12 can enter the liquid collecting channel 21 to be collected. The outlet 212 of the liquid collecting channel 21 is in communication with the liquid storage cavity 22, so that the collected condensate can enter the liquid storage cavity 22. Since the condensate in the gas channel 12 can be stored in the liquid storage cavity 22 through the liquid collecting channel 21 and is not prone to seep outwards, the user experience is improved.

[0046] The condensate collecting structure 2 includes a protruding portion 23 protruding into the liquid storage cavity 22, and the outlet 212 of the liquid collecting channel 21 is located on the protruding portion 23. By locating the outlet 212 of the liquid collecting channel 21 on the protruding portion 23, the condensate in the liquid storage cavity 22 is not prone to backflow from the liquid collecting channel 21 when the posture of the condensate collecting assembly is changed.

[0047] The protruding portion 23 can have any feasible structure. For example, in one embodiment, please refer to Figure 3 The condensate collecting structure 2 includes a top wall 24, a bottom wall 25 and a side wall 26 surrounding the liquid storage cavity 22. The top wall 24 is above the bottom wall 25 when the aerosol generating stick 3 inserted into the accommodation cavity 11 is being smoked. The side wall 26 connects the top wall 24 and the bottom wall 25, the liquid collecting channel 21 is located on the top wall 24, and the protruding portion 23 protrudes from the top wall 24 towards the bottom wall 25. This can better prevent the condensate from flowing out of the liquid collecting channel when the aerosol generating device is tilted or laid flat. In another embodiment, the liquid collecting channel 21 extends to the side wall 26, and the protruding portion 23 protrudes from the side wall 26 towards the center of the liquid storage cavity 22.

[0048] The aerosol generating stick 3 inserted into the accommodation cavity 11 being smoked refers to the state of smoking aerosol using the aerosol generating device.

[0049] In one embodiment, please refer to Figures 3 to 5 The protruding portion 23 is a flow guide column, one end of the flow guide column is a first end, and the other end is a second end. The first end is connected to the cavity wall of the liquid storage cavity 22, and the outlet 212 of the liquid collecting channel 21 is located on the second end. In some other embodiments, the protruding portion 23 can also be a boss, or a semispherical protrusion, or any other feasible shape.

[0050] To facilitate the discharge of the condensate, further, in one embodiment, please refer to Figures 3 to 5The condensate collecting structure 2 further has a liquid discharge channel 27, which is in communication with the liquid storage cavity 22 and has an outlet 271 facing the air inlet 112 of the accommodating cavity 11, so that the condensate is discharged through the outlet 271 of the liquid discharge channel 27, the air inlet 112 and the insertion opening 111 in sequence at least when the condensate collecting assembly is inverted. The condensate can be discharged at any time through the liquid discharge channel 27, avoiding leakage of the condensate in the liquid storage cavity 22.

[0051] The inversion of the condensate collecting assembly refers to the state that the insertion opening 111 faces downward when the aerosol generating device is not used to suck the aerosol.

[0052] In some other embodiments, the condensate can be discharged by any other feasible way in addition to inverting the condensate collecting assembly, such as by disassembling the aerosol generating device. In some other embodiments, the condensate collecting structure 2 can also be free of the liquid discharge channel 27, and the condensate can be cleaned by periodically disassembling the condensate collecting structure 2, or the condensate collecting structure 2 is a disposable structure, and the condensate collecting assembly is discarded after the liquid storage cavity 22 is full.

[0053] Further, in an embodiment, please refer to Figures 3 to 5 The liquid collecting channel 21 and the liquid discharge channel 27 are both on the top wall 24, the side wall 26 of the liquid storage cavity 22 is spaced apart from the outlet 212 of the liquid collecting channel 21 and spaced apart from the inlet 272 of the liquid discharge channel 27. In this way, the condensate is not easy to flow back from the outlet 212 of the liquid collecting channel 21 or to be discharged from the inlet 272 of the liquid discharge channel 27 when the condensate collecting assembly is placed horizontally.

[0054] Specifically, in an embodiment, please refer to Figures 3 to 5 The liquid discharge channel 27 is a liquid discharge hole on the top wall 24, the extension direction of the liquid discharge hole is consistent with the insertion direction of the aerosol generating rod 3, and one end of the liquid discharge hole is opposite to the air inlet 112 of the accommodating cavity 11.

[0055] In an embodiment, please refer to Figures 3 to 5 The number of the liquid collecting channels 21 is three, and the liquid collecting channels 21 are uniformly arranged around the liquid discharge channel 27. The specific number of the liquid collecting channels 21 can be increased or decreased as needed, and can be two, four or any number greater than five.

[0056] In some other embodiments, the liquid discharge channel 27 and the liquid collecting channel 21 can also use any other feasible arrangement, such as that the liquid collecting channel 21 extends to the side wall 26, the outlet 271 of the liquid discharge channel 27 is at the center of the top wall 24, and the inlet 272 is at the edge of the top wall 24.

[0057] Further, in one embodiment, please refer to Figure 3 When the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the inlet 211 of the liquid collecting channel 21 is lower than the outlet 271 of the liquid discharging channel 27. When the condensate collecting assembly is inverted, the inlet 272 of the liquid discharging channel 27 is lower than the outlet 212 of the liquid collecting channel 21. In this way, condensate collection is facilitated, and condensate can be smoothly discharged when inverted.

[0058] In some other embodiments, when the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the inlet 211 of the liquid collecting channel 21 can also be higher than the outlet 271 of the liquid discharging channel 27, and the condensate can also enter the liquid storage cavity 22 through the liquid discharging channel 27. Of course, in some other embodiments, the inlet 211 of the liquid collecting channel 21 can also be level with the outlet 271 of the liquid discharging channel 27.

[0059] Further, in one embodiment, please refer to Figure 3 The gas channel 12 includes a liquid collecting section 121 between the condensate collecting structure 2 and the airway assembly 1, and the inlet 211 of the liquid collecting channel 21 communicates with the bottom of the liquid collecting section 121.

[0060] In one embodiment, please refer to Figure 3 The gas channel 12 includes an upstream section 122 upstream of the liquid collecting section 121 and a downstream section 123 downstream of the liquid collecting section 121, and when the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the upstream section 122 is positioned higher than the liquid collecting section 121, and the downstream section 123 is positioned higher than the liquid collecting section 121. The upstream section 122 positioned higher than the liquid collecting section 121 can cause the condensate in the upstream section 122 to flow into the liquid collecting section 121, and the downstream section 123 positioned higher than the liquid collecting section 121 can cause the condensate in the downstream section 123 to flow into the liquid collecting section 121, thereby better preventing the condensate from flowing out.

[0061] In some other embodiments, the gas channel 12 can also include only the upstream section 122 upstream of the liquid collecting section 121. In some other embodiments, when the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the upstream section 122 can also be partially lower than the liquid collecting section 121 and partially higher than the liquid collecting section 121. In some other embodiments, when the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the upstream section 122 can also be entirely lower than the liquid collecting section 121, and the condensate in the upstream section 122 can be directly discharged or adsorbed by the liquid storage cotton.

[0062] Further, in one embodiment, please refer to Figure 3, the sump 121 comprises a sump bottom wall, at least a portion of the sump bottom wall is arched towards the accommodating cavity 11, the liquid discharge passage 27 is located on the arched portion of the sump bottom wall, and when the condensate collecting assembly is inverted, the inlet 272 of the liquid discharge passage 27 is lower than the outlet 212 of the liquid collecting passage 21. In this way, the condensate in the liquid storage cavity 22 can be completely drained.

[0063] It should be noted that the sump 124 is separated from the liquid storage cavity 22 by the sump bottom wall of the sump 124, that is, the top wall 24 of the liquid storage cavity 22.

[0064] In one embodiment, referring to Figure 3 , the sump bottom wall has an inner side facing the sump 124 and an outer side facing the liquid storage cavity 22, the inlet 272 of the liquid discharge passage 27 is located on the outer side, and when the condensate collecting assembly is inverted, the inlet 272 of the liquid discharge passage 27 is located at the lowest position of the outer side, so that the condensate in the liquid storage cavity 22 can be completely drained. In some other embodiments, the outer side can also be a flat surface.

[0065] In particular, in one embodiment, referring to Figure 3 and Figure 4 , the sump bottom wall comprises an arched portion 1241 and a flat bottom portion 1242 located at the periphery of the arched portion 1241, and the liquid collecting passage 21 is located on the flat bottom portion 1242. In this way, the condensate drops on the arched portion 1241 can flow to the flat bottom portion 1242, and then enter the liquid storage cavity 22 through the liquid collecting passage 21 of the flat bottom portion 1242. When the condensate in the liquid storage cavity 22 is discharged, the condensate collecting assembly is inverted, and at this time the arched portion 1241 is arched downward, so that the condensate in the liquid storage cavity 22 can flow to the arched portion 1241, and finally be discharged through the liquid discharge passage 27.

[0066] In some other embodiments, in addition to the arched middle portion, the sump bottom wall can also adopt any other feasible manner, such as an inclined arrangement. When the aerosol generating stick 3 inserted into the accommodating cavity 11 is being smoked, the inlet 211 of the liquid collecting passage 21 is lower than the outlet 271 of the liquid discharge passage 27, and when the condensate collecting assembly is inverted, the inlet 272 of the liquid discharge passage 27 is located at a lower position, and the outlet 212 of the liquid collecting passage 21 is located at a higher position. For example, in some other embodiments, the entire sump bottom wall can be arched, the edge of the arched portion 1241 is the edge of the sump bottom wall, and at this time the liquid collecting passage 21 is also located on the arched portion.

[0067] In some other embodiments, when the sump bottom wall is thick, it can also not be arched. A portion of the outer side of the sump bottom wall facing the liquid storage cavity 22 is recessed, the inlet 272 of the liquid discharge passage 27 is located in the recessed portion of the outer side, and the inner side of the sump bottom wall facing the sump 124 is a flat surface.

The sleeving of the first channel pipe 151 and the second channel pipe 152 facilitates the design of the gas channel 12. In some other embodiments, the airway assembly 1 can also be connected with the outside through a gas pipe.

[0073] Specifically, in one embodiment, referring to Figure 3The first channel tube 151 and the second channel tube 152 are both inserted into the top cover 14, and the annular channel 16 is formed between the first channel tube 151 and the second channel tube 152, and the annular channel 16 is part of the gas channel 12.
