Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and more specifically to a liquid storage device and an atomization device. Background Art

[0002] Atomizers can convert atomized substrates into aerosols by heating without burning them. The atomizers are equipped with a liquid storage structure and a heating structure that stores the atomized substrate.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0024] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0025] 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).

[0026] See also Figures 1 to 6 The present application provides an atomization device, including an atomization device 100, which can heat an atomization matrix to generate an aerosol that can be used by a user. The atomization device 100 includes a medium (such as liquid storage cotton) that can store the atomization matrix. However, due to the limited storage capacity of the medium, after the atomization matrix stored therein is exhausted, the atomization device 100 cannot continue to be used, and cannot meet the user's needs for long-term continuous use.

[0027] In order to improve the continuity of use of the atomizing device 100, an existing method is to use an additional rehydration mechanism to replenish the atomizing matrix in real time online, so that the atomizing device 100 will not be unable to continue to be used after the atomizing matrix stored in the atomizing device 100 is exhausted due to the limited storage capacity of the atomizing device 100 itself, thereby extending the use time of the atomizing device 100 and realizing continuous operation of the atomizing device 100, thereby improving the user's usage experience.

[0028] However, the existing fluid replenishment mechanism adopts a fluid replenishment bottle, a piston, a spring and a silicone ring. The silicone ring is clamped on the piston, and a spring is placed between the piston and the inner side of the fluid replenishment bottle. When the fluid replenishment bottle is connected to the atomizing device 100, the spring is squeezed by the ejector pin in the atomizing device 100, and the atomized matrix can enter the atomizing device 100. When the fluid replenishment bottle is pulled out, the spring resets and the atomized matrix can no longer seep out. Although this solution is reliable, it also has some shortcomings. The first is that the assembly is complicated. The second is that the spring can be seen outside the transparent fluid replenishment bottle, which is easy to cause user disgust. Finally, after the fluid replenishment bottle is installed, the spring is always squeezed. If a limiting structure is not added, the fluid replenishment bottle will be ejected. At this time, a buckle is needed to limit it. If the strength of the buckle is sufficient to resist the elastic force of the spring, it increases the difficulty of the user to replace the fluid replenishment bottle.

[0029] It should be noted that the term aerosol refers to a dispersion of solid or liquid particles in a gas. As used herein, "aerosol" may generally refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0030] As used herein, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butylene glycol, and glycerol; esters of polyols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanoic acid. The atomizing matrix may include nicotine. The atomizing matrix may include water. The atomizing matrix may include glycerol (also known as glycerol) having a higher boiling point than nicotine. The atomizing matrix may include propylene glycol. The atomizing matrix may include plant-based materials. The atomizing matrix may include a homogenized plant matrix material. The homogenized plant matrix material may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating.

[0031] The present application provides a liquid storage device 200, which is detachably connected to the atomizing device 100. On the basis of ensuring the basic fluid replenishment function, it can also realize timely fluid replenishment after being connected to the atomizing device 100, stop fluid replenishment after disassembly, and seal the atomized matrix. The structure is simple, which can simplify the assembly operation and solve the problem of unpleasant experience such as seeing foreign objects such as springs in a transparent fluid replenishment bottle.

[0032] In some embodiments, in order to increase the rehydration capacity, the liquid storage device 200 can be provided in plurality, for example, two, three or four, etc., and the plurality of liquid storage devices 200 are symmetrically and evenly arranged on the atomizing device 100, such as Figure 1 and Figure 2 As shown, there are two liquid storage devices 200 , which are symmetrically arranged on the atomization device 100 along the horizontal direction X.

[0033] It should be further explained that the atomizing device 100 is generally placed vertically when in use. Based on this placement habit, the longitudinal direction Y involved in this application is the vertical direction, which is also the extension direction of the liquid outlet channel 212 of this application, and the transverse direction X is the direction perpendicular to the vertical direction.

[0034] See also Figures 2 to 6 The liquid storage device 200 includes a liquid storage tank 210 and a sealing member 220 provided on the liquid storage tank 210. The liquid storage tank 210 includes a liquid storage cavity 211 and a liquid outlet channel 212. The liquid storage cavity 211 is used to store the atomized matrix. One end of the liquid outlet channel 212 can be communicated with the liquid storage cavity 211, and the other end is communicated with the atomizing device 100, so as to realize the communication between the liquid storage cavity 211 and the atomizing device 100. The sealing member 220 is provided at the liquid outlet channel 212, so as to seal the liquid outlet channel 212, so that the atomized matrix in the liquid storage cavity 211 cannot flow into the atomizing device 100 through the liquid outlet channel 212.

[0035] See also Figure 3 and Figure 4 In some embodiments, the sealing member 220 includes an elastic membrane 221 and a sealing membrane 222. The elastic membrane 221 and the sealing membrane 222 are sequentially arranged along the extension direction of the liquid outlet channel 212 (i.e., the Y direction). The liquid storage device 200 has a first state and a second state. In the first state, the sealing membrane 222 is punctured by force, and the elastic membrane 221 is deformed toward the inside of the liquid storage chamber 211 by force to open the liquid outlet channel 212. In the second state, the elastic membrane 221 seals the liquid outlet channel 212. After the liquid outlet channel 212 is opened, the atomized substrate can flow from the liquid storage chamber 211 through the liquid outlet channel 212 into the atomizing device 100. After the liquid outlet channel 212 is sealed, the atomized substrate is sealed and stored in the liquid storage chamber 211.

[0036] It should be further explained that the liquid storage device 200 has two forms in the second state. The first is the unused state after leaving the factory. At this time, the elastic membrane 221 is in an unstressed state, and the sealing membrane 222 is intact. The elastic membrane 221 and the sealing membrane 222 work together to seal the liquid outlet channel 212. The second is after use. At this time, the sealing membrane 222 has been destroyed, but because the elastic membrane 221 recovers its deformation, the elastic membrane 221 alone seals the liquid outlet channel 212.

[0037] The present application provides a double sealing protection for the entire liquid storage chamber 211 by arranging an elastic membrane 221 and a sealing membrane 222 in the liquid outlet channel 212, thereby preventing leakage of the atomized matrix and effectively ensuring the safe transportation and storage of the liquid storage device 200. By making full use of the elastic properties of the elastic membrane 221, it can be deformed and opened when subjected to a large external force (excluding the force of the atomized matrix), so that the atomized matrix in the liquid storage chamber 211 can flow out through the liquid outlet channel 212, and can also be restored to a sealed state after the force disappears, so that the liquid outlet channel 212 is sealed, thereby sealing the atomized matrix in the liquid storage chamber 211, simplifying the rehydration process, and being simple and convenient to operate. Compared with the structure of the spring and piston, the structure is simple, which facilitates the user to replenish or reuse the liquid storage device 200, avoids leakage when replacing or pulling out the liquid storage device, and avoids the appearance of foreign matter in the liquid storage tank 210, thereby avoiding causing user disgust.

[0038] In some embodiments, the sealing film 222 is made of aluminum foil, has good sealing properties, and has high resistance in relatively harsh environments such as negative pressure or high temperature. Therefore, it can cope with the high temperature and negative pressure tests of the liquid storage device 200 when it leaves the factory, and can also cope with various environments during transportation and storage, thereby improving the resistance of the liquid storage device 200 and avoiding leakage during transportation or in negative pressure, high and low temperature environments.

[0039] In some embodiments, the elastic membrane 221 is disposed on the side of the liquid outlet channel 212 close to the liquid storage chamber 211 to seal the liquid storage chamber 211. The sealing membrane 222 is coated on the outer wall of the liquid outlet channel 212 on the side away from the liquid storage chamber 211 to seal the liquid outlet channel 212. Specifically, the elastic membrane 221 is disposed inwardly relative to the sealing membrane 222. The sealing membrane 222 can provide a certain degree of protection for the elastic membrane 221, preventing the elastic membrane 221 disposed externally from being deformed by other external forces and causing leakage. In the second state described above after the sealing membrane 222 is destroyed, since the elastic membrane 221 is disposed close to the liquid storage chamber 211, the entire liquid storage tank 210 can also provide protection for the elastic membrane 221.

[0040] Of course, in other embodiments, the setting positions of the sealing membrane 222 and the elastic membrane 221 can be swapped with the above-mentioned embodiments, that is, the sealing membrane 222 is relatively set inside, and the elastic membrane 221 is relatively set outside. In order to protect the elastic membrane 221, the elastic membrane 221 can be set in the liquid outlet channel 212, and the elastic membrane 221 is protected by relying on part of the outer wall of the liquid outlet channel 212.

[0041] See also Figure 5The elastic membrane 221 includes a plurality of arcuate membrane petals 2211 and an annular connector 2212. The plurality of arcuate membrane petals 2211 are evenly arranged around the center of the annular connector 2212. One end of the plurality of arcuate membrane petals 2211 is connected to form an integral structure through the annular connector 2212, and the adjacent edges of the other ends of the plurality of arcuate membrane petals 2211 are elastically fitted. Specifically, the ends of the plurality of arcuate membrane petals 2211 away from the center of the annular connector 2212 are connected to form an integral structure through the annular connector 2212, and the adjacent edges of the ends close to the center are elastically fitted. After the elastic membrane 221 is deformed by an external force, the plurality of arcuate membrane petals 2211 are deformed toward the liquid storage chamber 211, and the adjacent edges are separated to form a gap for liquid to pass through, so that the atomized matrix can pass through. After the external force is removed, the arcuate membrane petals 2211 return to the elastically fitted form, the gap disappears, and the atomized matrix cannot pass through to achieve sealing of the liquid storage chamber 211.

[0042] Furthermore, the above-mentioned elastic fitting includes the formation of close fitting of adjacent edges of the arc-shaped membrane petals 2211, and also includes the connection of adjacent edges of multiple arc-shaped membrane petals 2211, but the thickness of the connection between adjacent edges is small, and a gap can be formed after the external force is applied. After the external force is removed, the edges can be closely fitted again, so that the gap disappears.

[0043] See also Figure 2 In some embodiments, the atomizing device 100 is provided with a puncturing structure 120, which can puncture the sealing member 220 to open the liquid outlet channel 212 and connect the liquid outlet channel 212 with the atomizing device 100. Specifically, the puncturing structure 120 can puncture the sealing membrane 222 and cause the elastic membrane 221 to deform toward the inside of the liquid storage chamber 211 under force, thereby forming a gap for liquid to pass through. The atomized substrate can flow through the gap through the liquid outlet channel 212 and then into the atomizing device 100.

[0044] In some embodiments, the puncturing structure 120 is a liquid guide tube having a certain hardness. The liquid guide tube can apply force to open the liquid outlet channel 212 and use the channel inside to achieve drainage of the atomized matrix. To more easily puncture the sealing membrane 222 and open the elastic membrane 221 to form a gap, the end of the liquid guide tube facing the liquid storage device 200 has a sharp structure. For example, the cross-section of the end of the liquid guide tube is a triangle or multiple triangles arranged in a row at intervals.

[0045] In some embodiments, the atomizing device 100 includes a liquid inlet 110, and a puncturing structure 120 is arranged at the liquid inlet 110. After the liquid storage device 200 is installed, the puncturing structure 120 can be penetrated into the liquid outlet channel 212 and extend to the liquid storage chamber 211. The liquid outlet channel 212 is opened by the setting of the puncturing structure 120, connecting the liquid outlet channel 212 and the liquid inlet 110, thereby realizing the connection between the atomizing device 100 and the liquid storage chamber 211.

[0046] In other embodiments, the puncture structure 120 is a liquid-guiding rod made of a porous material, which can apply force to open the liquid outlet channel 212 and use the wicking effect to guide the atomized matrix. Specifically, the porous material can be a porous ceramic material, cotton or fiber material, etc. By guiding the liquid through the porous material, the rate of liquid flow can be limited to prevent leakage due to oversaturation. The holes in the porous material can also be used to achieve air pressure balance inside the atomizing device 100 and the liquid storage tank 210, ensuring continuous and stable liquid supply to the liquid storage device 200.

[0047] In some embodiments, the elastic membrane 221 bends toward the inside of the liquid storage cavity 211 when not under stress, which facilitates the puncture structure 120 to apply force and ensures that the elastic membrane 221 is not damaged when under stress.

[0048] In some embodiments, the liquid storage device 200 further includes a fixing frame 230, which is disposed on the side of the elastic membrane 221 facing the liquid storage chamber 211 and is used to fix the elastic membrane 221. The elastic membrane 221 deforms under the force of the puncture structure 120 and there is a risk of it falling into the liquid storage chamber 211. By providing the fixing frame 230, the side near the liquid storage chamber 211 is fixed, thereby preventing the elastic membrane 221 from falling under the force and causing sealing failure.

[0049] See also Figure 3 and Figure 4 The liquid storage tank 210 includes a liquid storage tank body 213 and a liquid storage cover 214. The liquid storage tank body 213 has an opening at one end. The liquid storage cover 214 is disposed at the opening and, together with the liquid storage tank body 213, forms a liquid storage cavity 211. The liquid storage cover 214 is provided with a liquid outlet channel 212. A fixing bracket 230 is fixedly disposed on one side of the liquid storage cover 214. An elastic membrane 221 is tightly disposed between the liquid storage cover 214 and the fixing bracket 230. The provision of the liquid storage tank body 213 and the liquid storage cover 214 facilitates disassembly and cleaning of the liquid storage tank 210, as well as filling of the liquid storage tank 210 with an atomized matrix, thereby extending the service life of the liquid storage tank 210.

[0050] In some embodiments, the liquid outlet channel 212 includes a first cavity 2121 and a second cavity 2122, and the second cavity 2122 and the first cavity 2121 are arranged in sequence along the liquid outlet direction of the liquid outlet channel 212 (which can be understood as a direction parallel to the Y direction and from the inside to the outside); the diameter of the first cavity 2121 is smaller than the diameter of the second cavity 2122, so as to form a first step structure 2124 between the first cavity 2121 and the second cavity 2122, and the elastic membrane 221 is arranged at the first step structure 2124, and at least part of the structure of the fixing frame 230 is inserted into the second cavity 2122, so that the elastic membrane 221 is pressed between the first step structure 2124 and the fixing frame 230, and the sealing film 222 is sleeved on the outer wall of the first cavity 2121.

[0051] In other embodiments, the fixing frame 230 includes a first portion 231 and a second portion 232, the first portion 231 and the second portion 232 are continuously arranged and have different diameters, the diameter of the first portion 231 is smaller than the second portion 232, so that an annular protrusion is formed between the first portion 231 and the second portion 232, and the liquid outlet channel 212 further includes a third cavity 2123, the diameter of the third cavity 2123 is larger than the diameter of the second cavity 2122, and the first cavity 2121, the second cavity 2122 and the third cavity 2123 are arranged along The liquid outlet channel 212 is arranged in the opposite direction of the liquid outlet direction (which can be understood as a direction parallel to the Y direction and from the inside to the outside) from the outside to the inside. A second step structure 2125 (the same shape as the first step structure 2124) is formed between the third cavity 2123 and the second cavity 2122 based on the size change. The first part 231 is inserted into the second cavity 2122, and the second part 232 is arranged in the third cavity 2123 and the annular protrusion is against the second step structure 2125, which facilitates the assembly and fixation of the fixing frame 230. Since the third cavity 2123 is arranged closer to the liquid storage chamber 211, this structural design of the fixing frame 230 can seal the connection position of the third cavity 2123 and the second cavity 2122, thereby preventing the atomized matrix from leaking from the connection between the fixing frame 230 and the liquid outlet channel 212.

[0052] It should be further explained that the “from inside to outside” mentioned in this application refers to the direction from the liquid storage cavity 211 along the liquid outlet channel 212 to the outside of the liquid storage cavity 211 , and the direction of “from outside to inside” is opposite to that of “from inside to outside”.

[0053] An annular sealing ring (not shown) is provided on the circumference of the fixing frame 230 to further enhance the sealing effect between the fixing frame 230 and the second cavity 2122 .

[0054] In some embodiments, to facilitate quick installation and removal of the liquid storage device 200, reduce the number of connection structures, and facilitate user refilling or replacement of the liquid storage device 200, a mounting groove 215 is formed on the outer wall of the liquid storage tank 210. The mounting groove 215 is used to accommodate part of the structure of the atomizing device 100. During installation, the installation groove 215 allows the liquid storage device 200 to be connected to the atomizing device 100 after pushing the liquid storage device 200 into or out of the atomizing device 100. Depending on the structural design of the atomizing device 100, the mounting groove 215 can extend along the horizontal direction X or along the longitudinal direction Y.

[0055] See also Figure 6 The mounting groove 215 is provided on the liquid storage tank body 213 and extends along the longitudinal direction Y, and the liquid storage device 200 can be assembled or removed along the transverse direction X. Of course, in other embodiments, the mounting groove 215 can also be provided on the liquid storage cover 214 and extend along the transverse direction X.

[0056] See also Figure 6 In some embodiments, a fixing structure 216 is provided in the mounting groove 215. The fixing structure 216 includes a groove or a protrusion. The provision of the fixing structure 216 can achieve positioning of the liquid storage device 200 and prevent the liquid storage device 200 from moving after installation. The atomization device 100 is provided with a corresponding positioning structure (not shown in the figure), which matches the fixing structure 216. For example, when the fixing structure 216 is a protrusion, the positioning structure is a groove; when the fixing structure 216 is a groove, the positioning structure is a protrusion.

[0057] To further ensure stable installation of the liquid storage device 200, multiple fixing structures 216 and positioning structures are provided, and the fixing structures 216 and positioning structures are arranged one-to-one. Preferably, the multiple fixing structures 216 and positioning structures are evenly arranged along the extension direction of the installation slot 215 (i.e., the assembly direction).

[0058] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
