DETAILED DESCRIPTION

[0027] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. 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.

[0028] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0029] In related technologies, aerosol generating devices may be in a low-pressure external environment or have high temperatures generated internally due to operation, resulting in the air pressure inside the liquid storage chamber being greater than the external air pressure. The aerosol matrix inside the liquid storage chamber may be squeezed and leak under the action of the internal and external pressure difference.

[0030] In order to solve the above technical problems, an atomizing device is provided in the embodiment of the present application. Figures 1 to 3 As shown, the atomizing device includes:

[0031] The housing assembly 1 has a liquid storage chamber 3, a pressure relief hole 6, a pressure relief channel 5, and a receiving chamber 10; the liquid storage chamber 3 is used to store the aerosol matrix; the pressure relief hole 6 is connected to the liquid storage chamber 3, and the pressure relief hole 6 is connected to the outside atmosphere through the pressure relief channel 5;

[0032] The pressure relief component 8 is arranged in the accommodating cavity 10; the pressure relief component 8 can movably cover the pressure relief hole 6; the pressure relief hole 6 is opened or closed by the pressure relief component 8, so that the pressure relief hole 6 is connected or isolated from the pressure relief channel 5 to adjust the pressure in the liquid storage cavity 3.

[0033] The atomization device in the embodiment of the present application includes a shell assembly 1, which can be formed by splicing one or more components; specifically, the shell assembly 1 can form a splicing structure by various components along the up and down, left and right, inside and outside, etc., and a liquid storage chamber 3 is formed inside the shell assembly 1, and the liquid storage chamber 3 is used to accommodate the aerosol matrix.

[0034] As the atomizer is used, the aerosol matrix in the liquid storage chamber 3 gradually decreases, and the reduced space is gradually occupied by air. During the operation of the atomizer, high temperatures will be generated in the internal chamber of the shell assembly 1, including the liquid storage chamber 3. The high temperature will cause the pressure of the air in the liquid storage chamber 3 to increase, thereby generating an air pressure difference between the liquid storage chamber 3 and the outside of the atomizer; or, when the atomizer is in a low-pressure environment such as a high-altitude area, the air pressure inside the liquid storage chamber 3 will also be greater than the external environment, thereby generating an air pressure difference. In order to balance the internal and external air pressure differences and prevent leakage of the aerosol matrix, the shell assembly 1 in the embodiment of the present application also has a pressure relief hole 6 and a pressure relief channel 5, wherein the pressure relief hole 6 connects the liquid storage chamber 3 and the pressure relief channel 5, which allows the air inside the liquid storage chamber 3 to pass through the pressure relief hole 6 and be discharged from the pressure relief channel 5, thereby balancing the internal and external pressure differences of the liquid storage chamber 3 and preventing leakage of the aerosol matrix.

[0035] At the same time, if the pressure relief hole 6 and the pressure relief channel 5 are only opened, there is a risk of the aerosol matrix leaking directly from the pressure relief hole 6, and it is easy for external dust to enter the liquid storage chamber 3 from the pressure relief hole 6. Therefore, please refer to Figure 4 In the embodiment of the present application, the atomizing device further includes a pressure relief assembly 8, which is disposed within the accommodating chamber and movably covers the pressure relief hole 6. Its function is to seal the pressure relief hole 6, thereby preventing the aerosol matrix from leaking from the pressure relief hole 6 and preventing external dust from entering the pressure relief hole 6. In order to balance the internal and external pressure differences, the pressure relief assembly 8 does not completely seal the pressure relief hole 6. Instead, the pressure relief assembly 8 can open the pressure relief hole 6 when needed, allowing the pressure relief hole 6 to connect to the pressure relief channel to adjust the pressure within the liquid storage chamber.

[0036] In some optional embodiments, in order to form an accommodating chamber 10 for accommodating the pressure relief assembly 8, the housing assembly 1 has a recessed portion 11 extending toward the interior of the liquid storage chamber, and the interior space of the recessed portion 11 forms the accommodating chamber 10; the pressure relief hole 6 is formed in the bottom wall of the accommodating chamber 10, wherein the bottom wall is the shell wall opposite to the opening of the accommodating chamber 10. The recessed portion 11 provided in the housing assembly 1 forms an accommodating chamber 10 for accommodating the pressure relief assembly 8, and the accommodating chamber 10 has an opening facing the exterior of the housing assembly 1; the recessed portion 11 extends toward the interior of the liquid storage chamber 3, and the extension direction is adjusted accordingly according to the different settings of the recessed portion 11; for example, if the recessed portion 11 is provided at the top of the housing assembly 1, then the recessed portion 11 extends toward the bottom of the housing assembly 1 along the height direction. The pressure relief hole 6 is formed on the bottom wall of the accommodating chamber 10, so the pressure relief hole 6 is basically parallel to the liquid level of the aerosol matrix in the liquid storage chamber 3; after the liquid level of the aerosol matrix drops, the air in the liquid storage chamber 3 can be evenly exposed to the pressure relief hole 6, so that the air pressure inside and outside the liquid storage chamber 3 can be balanced as soon as possible.

[0037] In order to allow the pressure relief hole 6 to adapt to the changes in the liquid level of the aerosol matrix in the liquid storage chamber 3, when the liquid level of the aerosol matrix is below the pressure relief hole 6, the air in the liquid storage chamber 3 can be connected to the pressure relief hole 6 as a whole, and the pressure relief hole 6 is arranged on the bottom wall of the accommodating chamber 10; since the pressure relief hole 6 is arranged on the bottom wall of the accommodating chamber 10, when the liquid level of the aerosol matrix in the liquid storage chamber 3 is above the pressure relief hole 6, the aerosol matrix blocks the pressure relief hole 6. At this time, the aerosol matrix in the liquid storage chamber 3 is almost full, and there is no need to balance the internal and external air pressures; when the liquid level of the aerosol matrix drops below the pressure relief hole 6, the pressure relief hole 6 is connected to the air in the liquid storage chamber 3 as a whole. Once the pressure relief hole 6 is opened by the pressure relief component 8, the pressure relief hole 6 will be connected to the pressure relief channel 5 as a whole, thereby achieving the balance of the internal and external air pressures of the liquid storage chamber 3.

[0038] To ensure the leak-proof performance of the pressure relief holes 6 while enhancing their ventilation performance, the number of pressure relief holes 6 can be multiple; each pressure relief hole 6 is arranged in a symmetrical array on the bottom wall. Providing multiple pressure relief holes 6 reduces the area of a single pressure relief hole 6, thereby reducing the possibility of aerosol matrix leakage from the pressure relief holes 6, while maintaining the exhaust function of the pressure relief holes 6. The pressure relief holes 6 can be distributed in a circular or square array, which is not limited in the present embodiment.

[0039] In some optional embodiments, in order to adjust the opening and closing of the pressure relief hole 6, please continue to refer to Figure 3 The pressure relief assembly 8 includes a valve member 81, which is elastically connected to the accommodating chamber 10. The valve member 10 can automatically move toward or away from the pressure relief hole 6 in the accommodating chamber 10 based on the pressure differential between the inside and outside of the liquid storage chamber to close or open the pressure relief hole 6. Under the action of the elastic connection, the valve member can abut against the pressure relief hole 6 to close the pressure relief hole 6. If the pressure differential between the inside and outside of the liquid storage chamber 3 is sufficient to overcome the elastic preload of the elastic connection, the valve member is pushed open by the air pressure, thereby opening the pressure relief hole 6 and connecting the pressure relief hole to the pressure relief channel, allowing the air inside the liquid storage chamber 3 to be discharged from the pressure relief hole 6, thereby balancing the air pressure inside and outside the liquid storage chamber 3. It is worth mentioning that when the pressure difference between the inside and outside of the liquid storage chamber 3 reaches a level sufficient to overcome the elastic preload force and cause the valve component to open the pressure relief hole 6, as the air inside the liquid storage chamber 3 is discharged, the air inside and outside the liquid storage chamber 3 will quickly reach equilibrium, and the pressure difference between the inside and outside will rapidly decrease. As a result, the valve component will quickly close the pressure relief hole 6 under the action of the elastic preload force to prevent leakage of the aerosol matrix and also prevent external flying dust from entering the liquid storage chamber 3.

[0040] In addition, the valve component 81 and the housing assembly 1 can also be movably connected by means of a snap connection, a rotation connection, etc., and the valve component 81 can be switched to a closed / open state of the pressure relief hole 6 automatically or manually.

[0041] Furthermore, since the accommodating chamber 10 is formed in the recessed portion 11, which is recessed from the exterior of the housing assembly 1 toward the interior of the housing assembly 1, locating the pressure relief assembly 8 within the accommodating chamber 10 can enhance the integrity of the entire housing assembly 1. From the perspective of the atomizer device, the outer contour of the entire atomizer assembly 7 is approximately a single unit. Furthermore, a raised portion extending away from the interior of the liquid storage chamber 3 can be formed on the housing assembly 1, and the accommodating chamber can also be located within the raised portion.

[0042] In some optional embodiments, in order to achieve automatic pressure relief, that is, to automatically balance the internal and external pressure differences when the air pressure in the liquid storage chamber 3 increases, and to prevent the aerosol matrix from leaking from the pressure relief hole 6, the pressure relief assembly 8 further includes an elastic member 82 and a fixing member 83; the fixing member 83 is fixedly connected to the housing assembly 1, and the elastic member 82 is elastically connected between the valve member 81 and the fixing member 83, and is used to provide an elastic preload force that causes the valve member 81 to move toward the pressure relief hole 6. The valve member 81 is used to block and open the pressure relief hole 6, and the elastic member 82 is used to provide an elastic preload force for the valve member 81, so that the valve member 81 is in a state of blocking the pressure relief hole 6 in its natural state, thereby preventing the aerosol matrix from leaking from the pressure relief hole 6. The fixing member 83 is used to form a fixed connection between the housing assembly 1, thereby fixing the elastic member 82 and the valve member 81 to the housing assembly 1 in turn, so that the valve member 81 can elastically move relative to the housing assembly 1. As an example, the liquid density of the aerosol matrix is approximately 1.5 kg / m³. The capacity of the aerosol matrix is set accordingly based on the size of the liquid storage chamber 3. The liquid storage height within the liquid storage chamber 3 is less than or equal to 40 mm. Based on 40 mm, according to the liquid pressure formula, the liquid pressure is approximately P = ρgh = 588.8 Pa. Taking the maximum liquid pressure within the liquid storage chamber 3 of approximately 588.8 Pa as an example, to ensure a certain margin, the pressure required to overcome the elastic preload provided by the elastic member 82 is greater than 600 Pa. Based on experience summarized from testing, the pressure threshold for leak prevention within the liquid storage chamber 3 is 20 kPa. That is, the pressure threshold P corresponding to overcoming the elastic preload of the elastic member 82 is in the range of 600 Pa ≤ P ≤ 20 kPa. Of course, the specific pressure threshold range corresponding to the elastic preload should be set according to the liquid composition of the aerosol matrix, the size of the liquid storage chamber, and other factors, and is not limited in the embodiments of this application.

[0043] According to the different directions of the elastic pre-tightening force provided by the elastic member 82 to the valve member 81, the elastic member 82 can make the valve member 81 contact with the pressure relief hole 6 by stretching or compressing. Figure 2 and Figure 3, which shows that the elastic member 82 is compressed to allow the valve member 81 to abut against the pressure relief hole 6. In this state, if the air pressure inside the liquid storage chamber 3 is too high, the valve member 81 is pushed, and the air in the liquid storage chamber 3 is discharged by opening the pressure relief hole 6 to balance the internal and external air pressures. At the same time, the elastic preload force provided by the elastic member 82 is also increased. The valve member 81 will quickly close the pressure relief hole 6 under the action of the elastic preload force, thereby completing the pressure relief process.

[0044] The fixing member 83 is fixedly connected to the housing assembly 1. The fixing member 83 and the housing assembly 1 can be assembled to form a fixed connection, or the fixing member 83 and the housing assembly 1 can be directly integrally formed. Figure 3 In some optional embodiments, the fixing member 83 may specifically include a fixedly connected connecting portion 84 and a cover portion 85; a connecting member 12 is provided in the accommodating chamber 10, with the connecting portion 84 and the connecting member 12 forming a fixed connection, and the cover portion 85 is arranged at the opening of the accommodating chamber 10; the pressure relief channel 5 is formed in the accommodating chamber 10. The valve member 81, the connecting portion 84, and the cover portion 85 each have a preset gap 86 with the shell wall of the accommodating chamber 10, and the preset gaps 86 are interconnected to form the pressure relief channel 5; the pressure relief channel 5 is sequentially connected to the pressure relief hole 6, the valve member 81, the connecting portion 84, the cover portion 85, and the outside atmosphere in a direction away from the liquid storage chamber 3. In other words, in the embodiment of the present application, the pressure relief channel 5 is formed in the accommodating chamber 10, and the pressure relief channel 5 is generated based on the preset gaps 86 between each component and the accommodating chamber 10; the pressure relief channel 5 is sequentially connected to the shell wall of the accommodating chamber 10 by the valve member 81, the connecting portion 84, and the cover portion 85 in a direction away from the pressure relief hole 6 and the outside atmosphere. The cover portion 85 is disposed at the opening of the accommodating chamber 10, and a predetermined gap 86 is defined between the cover portion 85 and the recessed portion 11. Thus, while the cover portion 85 provides dust protection, it does not affect the exhaust function of the pressure relief passage 5, allowing gas exhausted from the liquid storage chamber 3 to be discharged externally through the predetermined gap 86. The connecting portion 84 is fixedly connected to the connector 12 disposed within the recessed portion 11, thereby forming a fixed connection between the connecting portion 84 and the housing assembly 1.

[0045] Specifically, the fixed connection between the communication portion 84 and the connecting member 12 can be formed by interference fit based on the shaft hole, or can be achieved by threaded fit.

[0046] In some optional embodiments, to automatically open and close the pressure relief hole 6, the pressure relief hole 6 is located within the contour coverage of the valve member 81. There are multiple pressure relief holes 6, each of which is arranged around the central axis of the valve member 81. In this case, the pressure relief holes 6 can be symmetrically arranged around the central axis of the valve member 81.

[0047] In some alternative embodiments, please refer to Figure 5The atomizing device also includes an atomizing assembly 7; the shell assembly 1 can be an integral structure, or a structure formed by a combination of two or more components, that is, the shell assembly 1 can specifically include a shell body 13 and a base 14, the shell body 13 has an opening, the base 14 is arranged at one end of the opening of the shell body, and the shell body 13 and the base 14 enclose a liquid storage chamber 3; the atomizing assembly 7 is fixedly arranged on the base 14 and is located in the liquid storage chamber 3; the atomizing assembly 7 is provided with a liquid inlet hole 4 connected to the liquid storage chamber 3, the liquid inlet hole 4 is arranged on the side close to the base 14, and the pressure relief hole 6, the pressure relief channel 5 and the pressure relief assembly 8 are arranged on the side away from the base 14. Among them, the shell body 13 and the base 14 are sealed. The sealing performance of the connection between the shell body 13 and the base 14 can be enhanced by setting a part of the structure in the base 14 as an elastic connection structure. An air inlet channel 15 is formed on the base 14 to provide an air intake path for the atomizing assembly 7; when the base 14 is composed of multiple components, the air inlet channel 15 is formed by passing through each component in sequence. The accommodating cavity 10 on the housing assembly 1 is arranged on a side away from the base 14, and the pressure relief hole 6, the pressure relief channel 5 and the pressure relief assembly 8 are also arranged on a side away from the base 14. For example, Figure 2 and Figure 4 In the example shown, the accommodating cavity 10, the pressure relief hole 6, the pressure relief channel 5, and the pressure relief assembly 8 are arranged on the side of the mouthpiece of the housing assembly 1. When the aerosol matrix in the liquid storage cavity 3 is consumed and a pressure difference occurs with the outside, the cavity in the housing assembly 1 can quickly expose the pressure relief hole 6, the pressure relief channel 5, and the pressure relief assembly 8. The pressure relief assembly 8 opens the pressure relief hole 6 to adjust the pressure in the liquid storage cavity 3. It should be noted that Figure 2 and Figure 4 The method of setting it on one side of the nozzle is only an example, and it can also be set on the side of the shell component 1, such as the side in the thickness direction, without sticking to the limitations of the embodiments of the present application.

[0048] The housing assembly 1 also has an air flow channel 2 and a liquid inlet 4. The liquid inlet 4 is used to introduce the aerosol matrix into the air flow channel 2, so that the atomizing assembly 7 disposed in the air flow channel 2 heats the aerosol matrix to generate aerosol, and the generated aerosol is discharged from the air flow channel 2. Figure 5In order to form an air flow channel 2 that is relatively independent of the liquid storage chamber 3, the shell assembly 1 has an atomizer tube 21, which can be integrally formed with the shell assembly 1, or can also be fixedly connected to the shell assembly 1. The atomizer tube 21 is inserted into the liquid storage chamber 3, and a liquid inlet hole 4 is formed on the tube wall of the atomizer tube 21. The liquid inlet hole 4 connects the internal space of the atomizer tube 21 with the liquid storage chamber 3, so that the aerosol matrix in the liquid storage chamber 3 can pass through the liquid inlet hole 4 and enter the atomizer tube 21. If the atomizer tube 21 is fixedly connected to the shell assembly 1, in order to improve the sealing of the connection, an elastic sealing member including a silicone member can be provided at the connection between the atomizer tube 21 and the shell assembly 1 to achieve a sealed connection between the atomizer tube 21 and the shell assembly 1.

[0049] The atomizer assembly 7 is arranged within the airflow channel 2, covering the liquid inlet 4. Therefore, when the aerosol matrix enters the airflow channel 2 through the liquid inlet 4, it is heated by the atomizer assembly 7 to produce an aerosol. The produced aerosol is then discharged from the housing assembly 1 along the airflow channel 2. To facilitate inhalation by the user, the housing assembly 1 generally also includes a mouthpiece, the shape of which matches the human mouth. The airflow channel 2 is connected to the outside world through the mouthpiece, thereby discharging the aerosol from the mouthpiece. The mouthpiece can be integrally formed with the housing assembly 1 or fixedly connected to the housing assembly 1.

[0050] The liquid inlet 4 is arranged away from the air outlet of the air flow channel 2, wherein the air outlet of the air flow channel 2 is the port for discharging the aerosol matrix to the atomizing device. The liquid inlet 4 is arranged away from the air outlet, which is equivalent to the liquid inlet 4 being arranged in the bottom area of the liquid storage chamber 3, which can improve the utilization rate of the aerosol matrix in the liquid storage chamber 3 and reduce the aerosol matrix in the liquid storage chamber 3 below the position of the liquid inlet 4.

[0051] In addition, to achieve a good leak-proof effect, the pressure relief channel 5 and the air flow channel 2 in the embodiment of the present application are arranged in parallel, that is, the pressure relief channel 5 and the air flow channel 2 extend in the same direction, specifically the height direction of the atomizer device. Since the pressure relief channel 5 and the air flow channel 2 are arranged in parallel along the height direction of the atomizer device, when the atomizer device is in normal use, the liquid level of the aerosol matrix in the liquid storage chamber 3 is perpendicular to the height direction, and the liquid level of the aerosol matrix is parallel to the end of the pressure relief hole 6, which can effectively reduce the risk of aerosol matrix leakage from the pressure relief hole 6.

[0052] In some optional embodiments, the base 14 forms a liquid absorption space, in which a liquid absorption member 18 is fixedly disposed; the liquid absorption member 18 encloses an air inlet channel 15, which is connected to the atomization assembly 7. One or more liquid absorption members 18 can be provided according to the shape of the accommodating space, and each liquid absorption member 18 is directly connected to increase the absorption of the aerosol matrix. The liquid absorption member 18 encloses the air inlet channel 15, and a through hole can be provided through the liquid absorption member 18, and the through hole forms the air inlet channel 15; alternatively, multiple liquid absorption members 18 can be spliced together to form the air inlet channel 15 at the splicing point.

[0053] In some optional embodiments, to add aerosol matrix to the liquid storage chamber 3, the housing assembly 1 may further include a liquid infusion hole communicating with the liquid storage chamber 3. The housing assembly 1 also includes a sealing member 19 disposed at the liquid infusion hole for sealing the hole. The provision of the liquid infusion hole in the housing assembly 1 allows for replenishment of the aerosol matrix into the liquid storage chamber 3. The provision of the sealing member 19 seals the liquid infusion hole, preventing leakage of the aerosol matrix within the liquid storage chamber 3 through the liquid infusion hole.

[0054] An embodiment of the present application provides an atomization device. Since the pressure relief component can open or close the pressure relief hole connected to the liquid storage chamber, the pressure relief hole can be opened to relieve pressure when the air pressure in the liquid storage chamber is too high to balance the internal and external air pressures, and the pressure relief hole can be closed after the pressure relief is completed, which can effectively prevent the aerosol matrix from leaking and greatly improve the user experience.

[0055] The present application also provides an aerosol generating device, please refer to Figure 1 The aerosol generating device includes a power supply device and an atomizing device in the embodiment of the present application; the atomizing device is electrically connected to the power supply device, and the power supply device supplies power to the atomizing device.
