The aerosol-generating mechanism, its housing structure, and the aerosol-generating device will be described in detail with reference to fig. 1 to 10.

In some of these embodiments, an aerosol-generating device 900 is shown in fig. 1, comprising an aerosol-generating mechanism 700 and a power supply assembly 800; the power supply assembly 800 is configured to provide electrical energy to the aerosol-generating mechanism 700; the aerosol-generating mechanism 700 is an aerosol-generating mechanism 700 according to any of the embodiments described below for heating an aerosol-generating medium to generate an aerosol. Taking the aerosol-generating mechanism 700 as an example of an atomizing device, the aerosol-generating medium may be referred to as an atomizing medium.

Referring to fig. 2, the power supply assembly 800 is electrically connected to the heat generating assembly 200 of the aerosol-generating mechanism 700 and provides electrical power to the heat generating assembly 200. Specifically, the power module 800 includes a circuit board 810, a microphone 820, a charging port 830, and a battery 840, wherein the microphone 820 and the charging port 830 are respectively mounted on the circuit board 810, and the battery 840 is electrically connected to the heat generating module 200 through the circuit board 810 to supply power.

Referring to fig. 3, the heat generating component 200 is provided with a liquid guiding surface 210 and a heat generating surface 220, the liquid storage cavity 310 of the housing structure 300 is communicated with the liquid guiding surface 210, and the liquid storage cavity 310 comprising the housing structure 300 is directly communicated with the liquid guiding surface 210, or the liquid storage cavity 310 of the housing structure 300 is indirectly communicated with the liquid guiding surface 210 through an intermediate piece. The rest of the embodiments are analogized and will not be described in detail. In this embodiment, the liquid storage cavity 310 is indirectly connected to the liquid guiding surface 210 through the oil inlet 530 of the upper cover 500. Such a structural design achieves that the heat generating component 200 obtains liquid aerosol-generating medium from the reservoir 310 via its liquid guide surface 210. In this embodiment, the microphone 820 is electrically connected to the electrode 230 of the heat generating component 200 through the circuit board 810, and is electrically connected to the heat generating element inside the heat generating component 200 through the electrode 230, so as to realize air flow control heating, and the specific heating control manner is the conventional design of the aerosol generating device 900 or the aerosol generating mechanism 700 thereof, which is not an inventive point of the present application.

In some of these embodiments, the heat generating assembly 200 includes a liquid guide that obtains the aerosol-generating medium through the liquid guide surface 210 and passes to a heat generating element that heats the aerosol-generating medium to generate an aerosol that enters the vent conduit 330. The liquid absorbing piece can be made of porous materials, including fiber, cotton, porous ceramic, porous glass and the like, the heating element can be arranged in the liquid absorbing piece in a coating, printing, embedding or integrated forming mode and the like, the liquid absorbing piece absorbs aerosol generating medium in a liquid storage cavity 610 to be described below and transmits the aerosol generating medium to the heating element, and the heating element heats the aerosol generating medium to be atomized to form aerosol. Since the heating element is disposed in the liquid absorbing member and has a relatively small shape, which is not the application, the distinction between the liquid guiding member and the heating element is not shown in the drawings.

In this embodiment, the air duct 330 of the housing structure 300 is in communication with the heat generating surface 220; the heating surface 220 heats the aerosol-generating medium acquired by the heating component 200 to generate aerosol, and the aerosol enters the ventilation pipe 330 and is released to the outside through the air outlet 304 of the housing structure 300, which is in communication with the ventilation pipe 330.

In this embodiment, the sealing member 400 limits the heat generating component 200 in the housing structure 300, and cooperates with the heat generating component 200 and the housing structure 300 to seal the liquid storage cavity 310 together; the heat generating component 200 is sealed and fixed on the one hand, and the liquid storage cavity 310 is sealed so as not to leak the aerosol generating medium in the liquid storage cavity 310 from below along the gravity direction GG.

In this embodiment, the aerosol generating mechanism 700 is provided with an air inlet 630, the air inlet 630 is communicated with the heat generating surface 220, external air enters the aerosol generating mechanism 700 through the air inlet 630, and aerosol generated by the heat generating surface 220 contacting the heat generating component 200 is mixed and then enters the air duct 330 through the output port 550 of the upper cover 500 or enters the air duct 330 through the heat generating cavity 240 of the heat generating component 200.

In some of these embodiments, a housing structure 300 is shown in fig. 4, and as it is used in an aerosol-generating mechanism 700, may be referred to as a housing structure 300 for an aerosol-generating mechanism 700, the housing structure 300 being the housing structure 300 for an aerosol-generating mechanism 700. In this embodiment, the housing structure 300 is provided with a liquid storage cavity 310, a ventilation channel 320 and a ventilation pipe 330; referring to fig. 3 and 5 together, the liquid storage chamber 310 is provided to communicate with the liquid guiding surface 210 of the heat generating component 200 of the aerosol generating mechanism 700; the air duct 330 is configured to communicate with the heat generating surface 220 of the heat generating component 200, and the air duct 330 is provided with an air outlet 304 that communicates with the outside; in this structural design, the aerosol generated by the heating element 200 heated on the heating surface 220 is released from the air outlet 304 through the air duct 330.

The ventilation channel 320 is provided with a first port 301 and a second port 302 which are communicated with each other, and the ventilation channel 320 is provided to communicate with the outside through the second port 302 in combination with fig. 4 and 6; the liquid storage cavity 310 is communicated with the ventilation channel 320 through the first port 301; by the structural design, the problem that the liquid storage cavity 310 is unsmooth in discharging liquid due to negative pressure in the negative pressure state is solved by designing the ventilation channel 320 communicated with the outside; specifically, after the aerosol generating medium stored in the liquid storage cavity 310 enters the heating component 200 through the liquid guiding surface 210, the liquid storage cavity 310 forms a negative pressure area, so that external air sequentially enters the liquid storage cavity 310 through the second port 302, the ventilation channel 320 and the first port 301, thereby eliminating negative pressure, and solving the problem of unsmooth liquid discharge caused by negative pressure in the liquid storage cavity 310 due to the negative pressure state inside.

In some of these embodiments, the second port 302 is higher than the first port 301 in the direction of gravity G. In this embodiment, by setting the relative positional relationship between the first port 301 and the second port 302, the liquid aerosol-generating medium is prevented from leaking directly from the second port 302 through the ventilation channel 320; in combination with the third port 303, which will be described below, leakage of liquid aerosol-generating medium from the ventilation channel 320 directly out of the second port 302 is further avoided.

In various embodiments, the ventilation channel 320 is further provided with a third port 303 in communication with the first port 301 and the second port 302, and the third port 303 is disposed in communication with the liquid guiding surface 210 of the heat generating component 200. In such a structural design, the first port 301 and the second port 302 are communicated and are matched with the third port 303 to realize recycling of aerosol generating media entering the ventilation channel 320, so that the smoothness of the ventilation channel 320 is guaranteed, and the ventilation effect can be normally exerted; since the aerosol-generating medium entering the ventilation channel 320 is retrieved from the third port 303 to the liquid level 210 and enters the heat generating component 200, it is also advantageous to prevent leakage of the liquid aerosol-generating medium from the ventilation channel 320 out of the second port 302.

In some of the embodiments shown in fig. 4, the third port 303 is lower than the first port 301 and the second port 302 in the direction G of gravity; in some embodiments, the third port 303 is in communication with the liquid storage chamber 310 through the first port 301 and the liquid guiding surface 210, respectively; that is, the third port 303 is communicated with the liquid guiding surface 210 of the heat generating component 200, and is also communicated with the liquid storage cavity 310 through the first port 301 and the liquid guiding surface 210, respectively; such a structural design, when the liquid aerosol-generating medium enters the ventilation channel 320 from the liquid storage chamber 310 through the first port 301, the aerosol-generating medium may flow from the third port 303, which is low in the gravity direction G, into the heat generating component 200 through the liquid guiding surface 210, thereby being effectively used, avoiding accumulating in the ventilation channel 320 to deteriorate or overflowing from the second port 302 to the outside of the aerosol-generating device 900 or the aerosol-generating mechanism 700 or the housing structure 300.

Alternatively, in other embodiments, the third port 303 communicates with the fluid guide 210 through a one-way permeable membrane. The third port 303 may be directly connected to the liquid guiding surface 210 through a unidirectional permeable membrane, or an intermediate member such as a channel 540 may be disposed between the unidirectional permeable membrane and the liquid guiding surface 210, and the third port 303 may be indirectly connected to the liquid guiding surface 210 through the unidirectional permeable membrane via the intermediate member. By means of the structural design, the aerosol-generating medium at the third port 303 which is positioned at a low position in the gravity direction G can be permeated and reflowed into the liquid storage cavity 310 by ingeniously utilizing the structural characteristics of the unidirectional permeable membrane, so that the same beneficial effects are achieved, namely, the aerosol-generating medium entering the inside of the ventilation channel 320 can be effectively used.

To ensure that the reservoir 310 communicates with the ventilation channel 320 only through the first port 301, in some embodiments, as shown in fig. 3 and 4, the housing structure 300 for the aerosol-generating mechanism 700 further comprises a baffle 350 for spacing the reservoir 310 and the ventilation channel 320; in the direction G of gravity, the first port 301 is disposed at a top position of the baffle 350. In some of these embodiments, the housing structure 300 for the aerosol-generating mechanism 700 further comprises a baffle 350 for spacing the liquid storage chamber 310 and the ventilation channel 320; in the gravity direction G, the first port 301 is disposed at a top position of the baffle 350; also, in the direction of gravity G, the second port 302 is adjacent to a top position of the baffle 350 and the third port 303 is adjacent to a bottom position of the baffle 350; the third port 303 is respectively communicated with the liquid storage cavity 310 through the first port 301 and the liquid guiding surface 210; or the third port 303 is in communication with the liquid guide surface 210 through a one-way permeable membrane. The rest of the embodiments are analogized and will not be described in detail. Such a structural design is advantageous to avoid the aerosol-generating medium from entering the ventilation channel 320 through the first port 301 as much as possible, and to ensure that the ventilation channel 320 is in communication with the outside through the second port 302, so as to perform ventilation normally.

Further, in the present embodiment, as shown in fig. 3 and 4, the housing structure 300 for the aerosol-generating device 700 further includes an outer wall 340 and a tube wall 360, the tube wall 360 is connected to the outer wall 340, the tube wall 360 is used for forming the ventilation duct 330, and the baffle 350 is also connected to the outer wall 340 to form the ventilation channel 320; and, the outer wall 340 and the baffle 350 cooperate with the tube wall 360 to form the liquid storage chamber 310. Further, in some embodiments, the outer wall 340, the baffle 350, and the tube wall 360. The design is beneficial to producing the shell structure 300, improves the production efficiency, reduces the production cost, and is particularly suitable for producing and preparing the shell structure 300 made of plastic materials.

To better seal the reservoir 310 from below to limit the location of aerosol-generating medium flow therein, in some embodiments, as shown in fig. 3 and 5, the aerosol-generating mechanism 700 further comprises an upper cover 500, the upper cover 500 being positioned over the heat-generating component 200 such that the heat-generating component 200 is spaced from the reservoir 310, i.e. such that the reservoir 310 is spaced from the heat-generating component 200 by the upper cover 500. With such a structural design, the upper cover part 500 forms a first layer sealing system to restrict the aerosol-generating medium in the liquid storage chamber 310 from entering the heat generating component 200 only through the upper cover part 500. Specifically, in this embodiment, the upper cover 500 is provided with an oil inlet 530 and a channel 540 that are disposed at intervals, the liquid storage cavity 310 is communicated with the liquid guiding surface 210 through the oil inlet 530, and the ventilation channel 320 of the housing structure 300 is communicated with the liquid guiding surface 210 through the channel 540. For the embodiment with the third port 303, the ventilation channel 320 communicates with the channel 540 via the third port 303, which is designed such that the aerosol-generating medium entering the ventilation channel 320 can flow into the liquid guiding surface 210 via the channel 540, whereby an efficient use is obtained.

To better avoid leakage of the aerosol-generating medium, in some embodiments, as shown in fig. 3 and 5, the aerosol-generating mechanism 700 further includes a sealing sleeve 600, the sealing sleeve 600 is sleeved on the heat-generating component 200, and the upper cover 500 is disposed on the sealing sleeve 600; that is, the sealing sleeve 600 separates the upper cover 500 from the heat generating component 200, which plays a further role in sealing, and prevents the upper cover 500 and the heat generating component 200 from affecting the sealing effect therebetween due to factors such as manufacturing process. Specifically, in this embodiment, the sealing sleeve 600 is provided with an oil inlet opening 610 and a notch 620 that are disposed at intervals, the oil inlet 530 is communicated with the liquid guiding surface 210 through the oil inlet opening 610, and the channel 540 is communicated with the liquid guiding surface 210 through the notch 620. Namely, a seal protection is additionally added between the oil inlet 530 and the liquid guiding surface 210, and a seal protection is additionally added between the channel 540 and the liquid guiding surface 210, which is beneficial to avoiding the leakage of the aerosol-generating medium from the joint position of the upper cover 500 and the heating component 200 along the gravity direction G, thereby avoiding the possibility that the aerosol-generating medium contacts and damages electronic components, and further ensuring the product function realization of the aerosol-generating device 900 or the aerosol-generating mechanism 700 thereof and the service life of the product.

In some of these embodiments, as shown in fig. 6 and 7, when a negative pressure occurs at the air outlet 304 of the housing structure 300, i.e., when a negative pressure state occurs at the air outlet 304, for example, air is sucked at the air outlet 304; referring to fig. 8, external air enters the aerosol-generating device 900 or the aerosol-generating mechanism 700 thereof from the air inlet 630, and triggers the microphone 820 to activate the heating element of the heating assembly 200, so as to heat the aerosol-generating medium entering the liquid guide of the heating assembly 200 via the liquid guide surface 210, thereby generating aerosol, and then the aerosol is released out of the air outlet 304 via the air duct 330 along the air flow path 710. In this embodiment, the upper cover 500 may be divided into a first upper cover 510 and a second upper cover 520 based on the interval of the air flow paths 710, and it is understood that in some embodiments, the first upper cover 510 and the second upper cover 520 are connected to form a single body at other angles or directions.
