Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to liquid storage devices and aerosol generation apparatus. Background Technology

[0002] Aerosol generating devices are used to atomize a liquid matrix into an aerosol for users to inhale. To enable the aerosol generating device to have a large liquid capacity, existing technology provides an exemplary aerosol generating device, which includes a reservoir and an atomizer. The reservoir has a large liquid volume and can replenish the liquid matrix to the atomizer. For example, in patent CN210226898U, when the reservoir is in storage or transport, the first liquid storage chamber is sealed by a first sealing element, and the first liquid storage chamber is in a sealed state. When the reservoir is connected to the atomizer, the sealing element of the first sealing element is punctured by the liquid guide column on the atomizer, opening the liquid channel. However, after the liquid guide column punctures the sealing element, the sealing element can easily detach from the main body of the first sealing element and cover the liquid outlet, causing the reservoir to be unable to smoothly output the liquid matrix. Utility Model Content

[0003] To address the issue that after the liquid guide column punctures the sealing component, the sealing component easily covers the liquid outlet, leading to uneven liquid output from the reservoir.

[0004] This application provides an embodiment of a liquid reservoir, including:

[0005] First shell;

[0006] A first support, wherein a first liquid storage chamber for storing a liquid matrix is ​​defined between the first support and the first housing;

[0007] A first sealing element is located at least partially between the first housing and the first bracket. The first sealing element is provided with at least one liquid outlet and a plugging element. The plugging element is disposed in the liquid outlet for sealing the liquid outlet.

[0008] The sealing component includes a sealing part and a stress-weak part. The stress-weak part is located between the sealing part and the wall of the liquid outlet. The stress-weak part includes a first segment and a second segment. The stress at the first segment is less than the stress at the second segment. At least a portion of the first segment can be broken under external force and separated from the wall of the liquid outlet, so that the liquid matrix is ​​output from the liquid outlet.

[0009] In some embodiments, the thickness of the first segment is less than the thickness of the second segment.

[0010] In some embodiments, the first segment and the second segment are connected in a ring.

[0011] In some embodiments, the arc length of the first segment is greater than the arc length of the second segment.

[0012] In some embodiments, the reservoir includes a liquid blocking element, and the first seal is provided with a first liquid injection hole, the liquid blocking element being disposed at the first liquid injection hole.

[0013] In some embodiments, the first housing includes a first snap-fit ​​groove, the first bracket includes a first snap-fit ​​portion, and the first housing and the first bracket are connected by snap-fit ​​through the first snap-fit ​​groove and the first snap-fit ​​portion.

[0014] In some embodiments, the first seal includes an annular rib disposed on the side of the sealing member opposite to the first liquid storage cavity.

[0015] This application provides an embodiment of an aerosol generating apparatus, including a second support and the aforementioned liquid reservoir.

[0016] The second support defines a second reservoir for storing a liquid matrix, and the second support is provided with at least one outwardly extending hollow liquid guide column, which provides a channel for the liquid matrix to enter the second reservoir.

[0017] In some embodiments, the liquid guiding column has a first protrusion and a second protrusion, the first protrusion and the second protrusion being disposed at one end of the liquid guiding column away from the second liquid storage cavity, the first protrusion being further away from the second liquid storage cavity than the second protrusion.

[0018] In some embodiments, a groove is provided between the first protrusion and the second protrusion, the groove providing a path for the liquid matrix in the first reservoir to flow into the second reservoir.

[0019] In some embodiments, the liquid guide column has a first position and a second position relative to the first seal. When the liquid guide column is in the first position, the sealing member can prevent the liquid matrix from flowing out of the outlet hole. When the liquid guide column is in the second position, the outlet hole allows the liquid matrix in the first storage chamber to flow into the second storage chamber.

[0020] In some embodiments, the aerosol generating device includes a second housing, the first housing having a second snap-fit ​​portion, the second housing having a second snap-fit ​​groove and a third snap-fit ​​groove, wherein when the liquid guiding column is in the first position, the second snap-fit ​​portion is located in the second snap-fit ​​groove; and when the liquid guiding column is in the second position, the second snap-fit ​​portion is located in the third snap-fit ​​groove.

[0021] In some embodiments, the second support includes a liquid inlet located at one end of the liquid guide column orifice facing the second liquid storage chamber.

[0022] In some embodiments, the aerosol generating device includes a liquid storage element located within the second liquid storage chamber and abutting against the liquid inlet.

[0023] This application provides an embodiment of an aerosol generating apparatus, including:

[0024] First shell;

[0025] A first support, wherein a first liquid storage chamber for storing a liquid matrix is ​​defined between the first support and the first housing;

[0026] A first sealing element is located at least partially between the first housing and the first bracket. The first sealing element is provided with at least one liquid outlet and a plugging element. The plugging element is disposed in the liquid outlet for sealing the liquid outlet.

[0027] The second support defines a second liquid storage chamber for storing a liquid matrix. The second support is provided with at least one outwardly extending liquid guide column, which is configured in a tubular shape to provide a channel for the liquid matrix to enter the second liquid storage chamber.

[0028] The free end of the liquid guide column has a first protrusion and a second protrusion spaced apart from each other. The first protrusion is further away from the second liquid storage cavity than the second protrusion, so that when the liquid guide column is inserted into the liquid outlet, the first protrusion contacts the sealing member before the second protrusion.

[0029] The stress-weak part of the first seal of the liquid reservoir of this application includes a first section and a second section. The stress at the first section is less than that at the second section, making the first section easier to puncture and detach from the seal compared to the second section. After the seal is punctured, the second section remains connected to the seal, and then the first section flips to one side of the second section. In this way, the seal will not fall off the body of the first seal and enter the first liquid reservoir cavity, thus preventing the seal from covering the liquid outlet and facilitating a smoother output of the liquid matrix in the liquid reservoir.

[0055] One embodiment of this application provides a liquid reservoir 10, such as... Figure 1 and Figure 2As shown, the device includes a first housing 1, a first support 2, and a first seal 3. A first liquid storage chamber 11 for storing a liquid matrix is ​​defined between the first support 2 and the first housing 1. The first seal 3 is at least partially located between the first housing 1 and the first support 2. The first seal 3 is provided with at least one liquid outlet 31 and a sealing member 32. The sealing member 32 is disposed within the liquid outlet 31 for sealing the liquid outlet 31. The sealing member 32 includes a sealing portion 321 and a stress-weak portion 322. The stress-weak portion 322 is located between the sealing portion 321 and the wall of the liquid outlet 31. The stress-weak portion 322 includes a first segment 3221 and a second segment 3222. The stress at the first segment 3221 is less than the stress at the second segment 3222; for example, the shear stress at the first segment 3221 is less than the shear stress at the second segment 3222. When subjected to external shear force, the first segment 3221 preferentially separates from the wall of the liquid outlet 31. At least a portion of the first segment 3221 can be broken under external force and separated from the wall of the outlet hole 31, so that the liquid matrix is ​​output from the outlet hole 31.

[0056] The stress-weak portion 322 of the first seal 3 of the reservoir 10 of this application includes a first segment 3221 and a second segment 3222. The stress at the first segment 3221 is less than the stress at the second segment 3222, making the first segment 3221 easier to puncture and detach from the seal 321 compared to the second segment 3222. After the sealing member 32 is punctured, the second segment 3222 remains connected to the seal 321, and then the first segment 3221 flips to the side of the second segment 3222. In this way, the seal 321 will not fall off the body of the first seal 3 and enter the first reservoir cavity 11, thus preventing the seal 321 from covering the liquid outlet 31 and facilitating a smoother output of the liquid matrix in the reservoir 10.

[0057] In one embodiment of this application, the first sealing member 3 has a slope for guiding liquid on the side facing the first liquid storage cavity 11, and the liquid outlet 31 is opened on the slope, so that the liquid matrix in the first liquid storage cavity 11 can flow into the liquid outlet 31 along the slope.

[0058] In one embodiment of this application, the liquid matrix can be a liquid containing volatile tobacco substances, or a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include menthol, peppermint, spearmint oil, various fruit flavorings, etc., but are not limited to these. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical applications and electronic aerosol atomization.

[0059] In one embodiment of this application, the thickness of the first segment 3221 is less than the thickness of the second segment 3222, making the first segment 3221 easier to puncture than the second segment 3222.

[0060] In one embodiment of this application, the material of the first segment 3221 is different from that of the second segment 3222. When the first segment 3221 and the second segment 3222 are of the same thickness, the stress of the material of the first segment 3221 is less than that of the material of the second segment 3222, making the first segment 3221 easier to be punctured than the second segment 3222.

[0061] In one embodiment of this application, the first segment 3221 and the second segment 3222 are connected in a ring shape, so that the sealing part 321 and the liquid outlet 31 are sealed before the stress-weak part 322 is punctured. In one embodiment of this application, the cross-section of the liquid outlet 31 can be circular, elliptical, or polygonal, and correspondingly, the sealing part 321 can be circular, elliptical, or polygonal.

[0062] In one embodiment of this application, such as Figure 4 As shown, the arc length of the first segment 3221 is greater than that of the second segment 3222. After the sealing member 32 is punctured, the first segment 3221 with the larger arc length separates from the wall of the liquid outlet 31, while the second segment 3222 remains connected to the wall of the liquid outlet 31. This facilitates the sealing part 321 to flip from the first segment 3221 to the second segment 3222. In this way, the sealing part 321 will not fall off the main body of the first sealing member 3 and enter the first liquid storage chamber 11, thus preventing the sealing part 321 from covering the liquid outlet 31 and ensuring that the liquid matrix in the liquid storage tank 10 is output more smoothly.

[0063] In one embodiment of this application, such as Figure 3 and Figure 5 As shown, the first sealing element 3 includes an annular rib 35, which is disposed inside the liquid outlet 31 and located on the side of the sealing element 32 opposite to the first liquid storage cavity 11. This allows the liquid guide column 52 to be inserted into the liquid outlet 31, and before it breaks the sealing element 32, its outer surface first forms an interference fit with the annular rib 35, thus creating a seal between the liquid guide column 52 and the inner wall of the liquid outlet 31. Then, as the liquid guide column 52 is further inserted, it pierces the sealing element 32, preventing leakage of the liquid matrix in the first liquid storage cavity 11 during the process of the liquid guide column 52 piercing the sealing element 32.

[0064] In one embodiment of this application, the liquid reservoir 10 includes a liquid blocking element 4, and the first sealing element 3 is provided with a first liquid injection hole 33, with the liquid blocking element 4 disposed at the first liquid injection hole 33.

[0065] In one embodiment of this application, the first housing 1 includes a first snap-fit ​​groove 12, and the first bracket 2 includes a first snap-fit ​​portion 21. The first housing 1 and the first bracket 2 are connected by snap-fit ​​through the first snap-fit ​​groove 12 and the first snap-fit ​​portion 21.

[0066] In one embodiment of this application, the first housing 1 includes a suction nozzle 13 and an air tube 14. The suction nozzle 13 is disposed at one end of the first housing 1 and can be held in the mouth of a user. One end of the air tube 14 is connected to the suction nozzle 13 and extends into the interior of the first housing 1. In another embodiment of this application, the first sealing member 3 further includes a first through hole 34. The other end of the air tube 14 is connected to the first through hole 34, thereby allowing aerosol to pass through the first through hole 34 and the first air tube 14 to reach the suction nozzle 13.

[0067] One embodiment of this application provides an aerosol generating device 100, such as... Figure 7 and Figure 8 As shown, the device includes a second support 5 and the aforementioned liquid reservoir 10. The second support 5 defines a second liquid reservoir 51 for storing a liquid matrix. The second support 5 is provided with at least one outwardly extending hollow liquid guide column 52, which provides a channel for the liquid matrix to enter the second liquid reservoir 51. When the liquid guide column 52 punctures the sealing member 32 of the first sealing member 3, the liquid outlet 31 and the second liquid reservoir 51 are connected, and the liquid matrix in the first liquid reservoir 11 can flow into the second liquid reservoir 51.

[0068] See Figure 7 As shown, this application provides an embodiment of a liquid guiding column 52. The liquid guiding column 52 has a first protrusion 521 and a second protrusion 522, which are disposed at the end of the liquid guiding column 52 away from the second liquid storage cavity 51. The first protrusion 521 is further away from the second liquid storage cavity 51 than the second protrusion 522. When the liquid guiding column 52 pierces the sealing member 32 of the first sealing member 3, the first protrusion 521 corresponds to the first segment 3221, and the second protrusion 522 corresponds to the second segment 3222. This causes the sealing part 321 of the sealing member 32 to flip from the first segment 3221 to the second segment 3222 after the first protrusion 521 pierces the first segment 3221. The second protrusion 522 then squeezes the sealing part 321 between the liquid guiding column 51 and the liquid outlet 31, thus preventing the sealing member 32 from covering the liquid outlet 31 after the liquid guiding column 52 pierces the sealing member 32, which would otherwise cause the liquid to not flow smoothly from the reservoir 10.

[0069] In a further alternative example, a groove 523 is provided between the first protrusion 521 and the second protrusion 522, providing a path for the liquid matrix in the first reservoir 11 to flow into the second reservoir 51. When the guide column 52 punctures the sealing member 32 of the first seal 3, even if the liquid matrix in the first reservoir 11 is low, the liquid matrix can still pass through the groove 523 into the second reservoir 51.

[0070] Combination Figure 6 and Figure 8 As shown, in one embodiment of this application, the liquid guiding column 52 has a first position and a second position relative to the first sealing member 3. When the liquid guiding column 52 is in the first position (not shown in the figure), the sealing member 32 can prevent the liquid matrix from flowing out of the liquid outlet 31; when the liquid guiding column 52 is in the second position (as shown in the figure), the sealing member 32 can prevent the liquid matrix from flowing out of the liquid outlet 31. Figure 6 As shown), the liquid outlet 31 allows the liquid matrix in the first liquid storage chamber 11 to flow into the second liquid storage chamber 51.

[0071] See Figure 8 This demonstrates one of the ways in which the liquid guide column 52 has two movable positions. The aerosol generating device 100 includes a second housing 6, a first housing 1 having a second snap-fit ​​portion 15, and a second housing 6 having a second snap-fit ​​groove 61 and a third snap-fit ​​groove 62. When the liquid guide column 52 is in the first position, the second snap-fit ​​portion 15 is located in the second snap-fit ​​groove 61; when the liquid guide column 52 is in the second position, the second snap-fit ​​portion 15 is located in the third snap-fit ​​groove 62.

[0072] See Figure 6 As shown, the second support 5 includes a liquid inlet 53, located at the end of the liquid guide column 52 facing the second liquid storage chamber 51. The aerosol generating device 100 includes a liquid storage element 7, located within the second liquid storage chamber 51. The end of the liquid storage element 51 abuts against the liquid inlet 51, and the liquid matrix in the second liquid storage chamber 51 is absorbed and retained by the liquid storage element 7. When the liquid matrix in the second liquid storage chamber 51 is consumed, the air in the second liquid storage chamber 51 can at least partially enter the first liquid storage chamber 11 through the liquid outlet 31, adjusting the pressure difference between the first liquid storage chamber 11 and the second liquid storage chamber 51, thereby promoting the smooth supply of the liquid matrix in the first liquid storage chamber 11 to the second liquid storage chamber 51.

[0073] In one embodiment of this application, the second support 5 includes a second injection hole 54, which allows liquid matrix to be injected into the liquid storage component 7 of the second liquid storage chamber 51. In one embodiment of this application, the number of second injection holes 54 is four, which makes the liquid injection process of the second liquid storage chamber 51 faster and can quickly achieve automated liquid injection.

[0074] In one embodiment of this application, the second bracket 5 includes a third snap-fit ​​portion 57, and the second housing 6 includes a fourth snap-fit ​​groove 63. The second bracket 5 and the second housing 6 are snap-fitted together by the third snap-fit ​​portion 57 and the fourth snap-fit ​​groove 63.

[0075] See Figure 6 As shown, the aerosol generating device 100 further includes an atomizing component 8, which is disposed in the second liquid storage chamber 51 and is used to atomize the liquid matrix in the second liquid storage chamber 51 to generate aerosol. In one embodiment of this application, the second support 5 is provided with a second through hole 55. One end of the second through hole 55 is connected to the air pipe 14 through a first through hole 34, and the other end of the second through hole 55 is connected to the atomizing component 4, so that the aerosol generated by the atomizing component 4 can reach the air pipe 14 through the second through hole 55 and then reach the mouthpiece 13.

[0076] This application provides one embodiment of an atomizing component 8, which includes a support member and a liquid guiding component and a heating element located within the support member. As a specific example, the support member is a steel pipe, and the liquid guiding component has a liquid guiding surface and a heating surface arranged opposite each other. The liquid guiding surface is in fluid communication with a second liquid storage chamber. The liquid guiding component guides the liquid matrix from the liquid guiding surface to the heating surface. One side of the heating surface is an atomizing chamber. Under the heating of the heating element on the heating surface, the liquid matrix is ​​atomized to generate an aerosol that enters the atomizing chamber. As a specific example, the liquid guiding component includes a porous body, which can be a fiber, including but not limited to cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. For example, the liquid guiding component 8 can be made of an elastic organic porous material, which has a hardness or flexibility between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A). Therefore, its structure is stable, exhibiting extremely low expansion after absorbing and wetting the liquid matrix, while also possessing a certain degree of hardness that allows it to be easily fixed and maintained. As a suitable example, the liquid guiding element 8 can be rigid synthetic cotton. As alternative examples, the porous body can also be porous ceramic or porous metal, and this application does not limit the structure and composition of the porous body.

[0077] This application provides another embodiment of the atomizing component 8, which may include an ultrasonic element capable of high-frequency vibration under ultrasonic drive. The atomizing component 8 utilizes ultrasonic vibration to atomize a liquid matrix into an aerosol. Of course, the atomizing component 8 may also include other elements capable of atomizing a liquid matrix into an aerosol.

[0078] In one embodiment of this application, the aerosol generating device 100 further includes a battery assembly 9, and the second support 5 includes a battery receiving cavity 56, in which the battery assembly 9 is disposed. The battery assembly 9 provides electrical power to the atomizing assembly 8. In one embodiment of this application, the DC supply voltage provided by the battery assembly 9 is in the range of about 2.5V to about 9.0V, and the DC current provided by the battery assembly 9 is in the range of about 2.5A to about 20A. Typically, the battery assembly 9 is a rechargeable battery. Alternatively, the battery assembly 9 may be another form of charge storage device, such as a capacitor. The battery assembly 9 may require recharging and may have a capacity that allows for storing sufficient energy for one or more aspirations; for example, the battery assembly 9 may have sufficient capacity to allow continuous aerosol generation over a preset period of time. In another example, the battery assembly 9 may have sufficient capacity to allow the activation of a predetermined number of aerosol generating devices.

[0079] See Figure 6 As shown, one embodiment of this application provides an aerosol generating apparatus 100, including a first housing 1, a first support 2, a first seal 3, and a second support 5. A first liquid storage chamber 11 for storing a liquid matrix is ​​defined between the first support 2 and the first housing 1. The first seal 3 is at least partially located between the first housing 1 and the first support 2, and is provided with at least one liquid outlet 31 and a sealing member 32. The sealing member 32 is disposed within the liquid outlet 31 to seal the liquid outlet 31. A second liquid storage chamber 51 for storing a liquid matrix is ​​defined within the second support 5, and the second support 5 is provided with at least one outwardly extending liquid guide column 52, which is configured in a tubular shape to provide a channel for the liquid matrix to enter the second liquid storage chamber 51. The free end of the liquid guide column 52 has a first protrusion 521 and a second protrusion 522 spaced apart. The first protrusion 521 is further away from the second liquid storage cavity 51 than the second protrusion 522, so that during the process of inserting the liquid guide column 52 into the liquid outlet hole 31, the first protrusion 521 contacts the sealing member 32 before the second protrusion 522.

[0080] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification.
