Description

Technical Field

[0001] This application relates to the field of aerosol atomization technology, specifically to a liquid storage component and an atomizing device. Background Technology

[0002] In related technologies, to prevent leakage of the aerosol matrix in the atomizing device and to control the amount of aerosol matrix used, a liquid storage chamber is usually set up inside the atomizing device. This chamber contains a liquid storage element with a mesh-like porous structure, which adsorbs the liquid aerosol matrix internally through capillary effect. However, due to the mesh-like porous structure of the liquid storage element, its micropores usually contain air in addition to the aerosol matrix. When the device temperature rises due to the operation of the atomizing device, the air in the liquid storage element expands. If the expanded air cannot be discharged normally from the inside of the liquid storage element in time, it will compress the aerosol matrix inside the liquid storage element. This causes a large amount of aerosol matrix to be squeezed into the heating element, making the aerosol matrix prone to leakage and reducing the user experience. Utility Model Content

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0035] This application provides a liquid storage component in its embodiments. Please refer to... Figures 1-5 As shown, the liquid storage assembly includes: a housing 1, with a liquid storage chamber 10 formed inside the housing 1; the liquid storage chamber 10 has an outlet 111 and an inlet 121; wherein the liquid storage chamber 10 may have a top wall 11 and a bottom wall 12 arranged axially opposite to each other, and a side wall 13 connecting the top wall 11 and the bottom wall 12, the outlet 111 is formed in the top wall 11, and the inlet 121 is formed in the bottom wall 12; and a liquid storage component 2, disposed within the liquid storage chamber 10; the liquid storage component 2 has a connection between the outlet 111 and the inlet. Assembly through hole 21 of 121; heating assembly 3, the heating assembly 3 includes heating element 31 and air guide pipe 4, the air guide pipe 4 has a liquid guide hole 41 and an exhaust hole 42 through the pipe wall; the air guide pipe 4 passes through the assembly through hole 21 and is connected to the air outlet 111 and the air inlet 121; the heating element 31 is disposed in the air guide pipe 4 and covers the liquid guide hole 41, the heating element 31 is connected to the liquid storage component 2 through the liquid guide hole 41 to form a liquid passage, and the exhaust hole 42 is used to guide the gas in the liquid storage component into the air guide pipe 4 for discharge.

[0036] The liquid storage component in this embodiment is used to heat the aerosol matrix to generate an aerosol. The aerosol matrix is ​​a liquid substance. To contain the aerosol matrix, the shell 1 in this embodiment has a liquid storage chamber 10, which is a component of the liquid storage component, including the aerosol matrix.

[0037] The liquid storage chamber 10 can be formed by enclosing multiple walls. For example, the liquid storage chamber 10 may include a top wall 11 and a bottom wall 12 arranged axially opposite each other, and a side wall 13 connecting the top wall 11 and the bottom wall 12. A sealed connection is formed between the walls to prevent the aerosol matrix from leaking out from the connection between the walls. The top wall 11 and the bottom wall 12 are each provided with an air outlet 111 and an air inlet 121 communicating with the inside and outside of the liquid storage chamber 10. The air inlet 121 is used to draw in outside air during the operation of the liquid storage component and mix it with the heated aerosol matrix to form an aerosol. The air outlet 111 is used to discharge the generated aerosol to the outside.

[0038] To prevent the aerosol matrix from failing to remain within the storage chamber 10, this embodiment also includes a storage component 2. The storage component 2 is disposed within the storage chamber 10 and can store the aerosol matrix through adsorption. The storage component 2 has a mesh-like porous structure, which can adsorb the liquid aerosol matrix internally through capillary effect. Depending on the material, the storage component 2 may include storage cotton, ceramic components, etc. The storage component 2 can be a one-piece structure or formed by splicing multiple parts together. Of course, since the storage component 2 itself has a mesh-like porous structure, multiple pores are distributed on each of its surfaces, allowing communication between the interior and exterior of the storage component 2.

[0039] To prevent the liquid storage component 2 from affecting the generation and flow of aerosols, the liquid storage component 2 has an axially penetrating assembly through-hole 21, which connects to the air outlet 111 and the air inlet 121. In other words, within the liquid storage chamber 10, the liquid storage component 2 is arranged to avoid the air outlet 111 and the air inlet 121, thereby forming an assembly through-hole 21 between the air outlet 111 and the air inlet 121, allowing air and aerosols to flow through.

[0040] In order to heat the aerosol matrix to generate aerosol, the liquid storage component in this embodiment of the application further includes a heating component 3, wherein the heating component 3 is disposed in the assembly through hole 21, the aerosol matrix can flow out from the liquid storage component 2, generate aerosol after being heated by the heating component 3, and then be discharged through the assembly through hole 21.

[0041] Specifically, the heating assembly 3 includes a heating element 31 and a vent pipe 4. To prevent the aerosol matrix stored in the liquid storage unit 2 from flowing directly into the assembly through hole 21 and leaking from the air outlet 111, the vent pipe 4 is inserted into the assembly through hole 21. The wall of the vent pipe 4 can isolate the liquid storage unit 2 from the interior of the vent pipe 4, that is, isolate the liquid storage unit 2 from the assembly through hole 21. The vent pipe 4 can be integrally formed on the outer wall of the liquid storage tank 10, that is, the vent pipe 4 can be integrally formed with the top wall 11 / bottom wall 12; or, the vent pipe 4 can also be a separate component, installed in the assembly through hole 21 by assembly. The interior of the vent pipe 4 forms an atomization channel, which not only allows the heated and atomized aerosol to circulate, but also allows the air discharged from the exhaust port 42 to circulate, so that the air can be discharged from the liquid storage assembly.

[0042] To prevent the aerosol matrix from flowing directly into the assembly through-hole 21, the air guide pipe 4 partially isolates the liquid storage component 2 from the atomization channel. During the use of the liquid storage component, because the heating component 3 needs to operate by heating, all components in the entire liquid storage chamber 10 will be heated to a certain extent, and the air remaining inside the liquid storage component 2 will also expand due to the heat. In order to allow the expanded air to be discharged as quickly as possible, at least one exhaust hole 42 is provided on the wall of the air guide pipe 4 in this embodiment, that is, the exhaust hole 42 penetrates the wall of the air guide pipe 4. Since the exhaust hole 42 penetrates the wall of the air guide pipe 4, the exhaust hole 42 can connect the space between the liquid storage chamber 10 and the atomization channel. In particular, the air in the liquid storage component 2 can enter the assembly through-hole 21 through the exhaust hole 42, and then be discharged outward through the air outlet 111 connected to the assembly through-hole 21. Please refer to Figure 4 , Figure 4 The diagram shows air in the liquid reservoir 2 entering the assembly through-hole 21 through the vent 24 and further being discharged outward through the vent 111. The arrows indicate the direction of the exhaust. In other words, by adding a vent 42 to the air guide pipe 4 in this embodiment, air in the liquid reservoir 2 can enter the atomization channel through the vent 42. This not only limits the leakage of the aerosol matrix but also improves the path for air to exit from the liquid reservoir 2, further reducing the possibility of aerosol matrix leakage.

[0043] In order to heat the aerosol matrix to generate aerosol, a liquid guiding hole 41 is also provided through the pipe wall of the gas guiding pipe 4, which is equipped with the heating element 31. By providing the liquid guiding hole 41, the aerosol matrix in the liquid storage tank 10 can be guided to the heating element 31 for heating.

[0044] In some embodiments, please refer to Figure 6In order to improve the exhaust effect of the air duct 4, there are multiple exhaust holes 42, which are arranged around the air duct 4. By increasing the number of exhaust holes 42, exhaust holes 42 can exhaust from all directions of the air duct 4.

[0045] In some embodiments, the liquid guide hole 41 is disposed on the side of the air guide pipe 4 near the air inlet 121, and the exhaust hole 42 is disposed on the side of the air guide pipe 4 near the air outlet 111. By disposing the exhaust hole 42 closer to the air outlet 111, the exhaust gas can be directly discharged outward through the air outlet 111.

[0046] In some embodiments, for the purpose of arranging the air guide pipe 4 and the heating component 3, the structure of the housing 1 may specifically include a housing body 14 and an end seat 15, wherein the housing body 14 and the end seat 15 enclose a liquid storage chamber 10, and the air inlet 121 is disposed through the end seat 15; the end seat 15 is provided with a mounting groove 16, which surrounds the air inlet 121 and is formed on the inner wall of the end seat 15 facing the liquid storage chamber 10 for mounting the air guide pipe 4; the air guide pipe 4 may include a first pipe section 43 and a second pipe section 44 connected in sequence, the end of the first pipe section 43 away from the second pipe section 44 is connected to the air outlet 111, and the end of the second pipe section 44 away from the first pipe section 43 is inserted into the mounting groove 16; the heating component 31 is disposed on the second pipe section 44, and the exhaust port 42 is disposed through the pipe wall of the first pipe section 43. In this embodiment, the gas guide tube 4 can be composed of two pipe segments spliced ​​together, namely a first pipe segment 43 and a second pipe segment 44. The first pipe segment 43 and the second pipe segment 44 are fixedly connected to each other. The first pipe segment 43 and the second pipe segment 44 are respectively used to form an exhaust port 42 and a liquid guide port 41. The second pipe segment 43 is also used to set a heating component 3. The heating component 3 can receive the aerosol matrix stored in the liquid storage device 2 based on the liquid guide port 41, and then heat the aerosol matrix through the heating component 3.

[0047] In some embodiments, depending on the functional characteristics of the first pipe section 43 and the second pipe section 44, the first pipe section 43 can be configured as a porous fiber tube structure, and the second pipe section 44 can be configured as a metal tube structure; the first pipe section is inserted into the second pipe section; and / or, the second pipe section 44 is inserted into the first pipe section 43. The second pipe section 44 is used to install the heating component 3. Since the heating component 3 generates heat during operation, it needs to be made of a metal material with good thermal conductivity and high temperature resistance to ensure durability and thermal conductivity. The first pipe section 43 mainly functions to exhaust air; therefore, the first pipe section 43 can be made of a porous fiber tube. This facilitates the fabrication of exhaust holes 42 on the fiber tube, and the porous structure of the fiber tube itself also facilitates exhaust, thereby further improving the exhaust effect of the first pipe section 43.

[0048] In some embodiments, please refer to Figure 5 and Figure 7 The liquid storage tank 10 has a top wall 11 and a bottom wall 12 arranged axially opposite to each other, and a side wall 13 connecting the top wall 11 and the bottom wall 12. An air outlet 111 is located on the top wall 11, and an air inlet 121 is located on the bottom wall 12. A first exhaust groove 51 is formed on the surface of the top wall 11 facing the liquid storage tank 10, a second exhaust groove 52 is formed on the surface of the liquid storage component 2 facing the side wall 13, and a third exhaust groove 53 is formed on the surface of the bottom wall 13 facing the liquid storage tank 10. The first exhaust groove 51 connects to the air guide pipe 4 and the air outlet 111, and the second exhaust groove 52 connects to the first exhaust groove 51 and the third exhaust groove 53. In this embodiment, the shell 1 can be a single-layer structure or a multi-layer structure, and a covering layer can be formed outside the liquid storage tank 10. To facilitate the removal and placement of the liquid storage component 2, the liquid storage tank 10 can be formed by splicing two or more components, allowing the liquid storage tank 10 to be opened by disassembly for easy removal and placement of the liquid storage component 2. The housing 1 has a top wall 11 and a bottom wall 12 disposed opposite to each other, and a side wall 13 connecting the top wall 12 and the bottom wall 12. The top wall 11, bottom wall 12, and side wall 13 together enclose a liquid storage chamber 10. Correspondingly, an air outlet 111 is formed on the top wall 11, and an air inlet 121 is formed on the bottom wall 12. The air outlet 111 and the air inlet 121 are located at both ends of the assembly through hole 21 of the liquid storage component 2, respectively. In addition, in this embodiment, the structure of the housing 1 may include a shell body 14 and an end seat 15. The shell body 14 has a top wall 11 and a side wall 13, which is equivalent to forming the chamber body of the liquid storage chamber 10; the end seat 15 has a bottom wall 12, which is equivalent to forming the bottom cover of the liquid storage chamber 10. The shell body 14 and the end seat 15 form a sealed fixed connection with each other, which means that the shell body 14 and the end seat 15 are sealed at the connection to prevent the aerosol matrix from leaking from the connection. To improve the sealing effect, a sealing element can be provided on the housing 14 and / or the end seat 15. The elastic structure of the sealing element can achieve a relative seal between the housing 14 and the end seat 15. Correspondingly, the air outlet 111 is formed on the housing 14, and the air inlet 121 is formed on the end seat 15. To form a connection, one of the housing 14 and the end seat 15 can be provided with a plug-in portion, and the other can be provided with a corresponding slot. Inserting the plug-in portion into the slot achieves a fixed connection between the two. Then, the sealing element can be sleeved on the plug-in portion or embedded in the inner wall of the slot.

[0049] To further improve the venting performance of the liquid storage component 2, especially by directly utilizing the porous structure of the liquid storage component 2 itself to allow the gas stored inside the liquid storage component 2 to be directly discharged from the outer surface of the liquid storage component 2, in this embodiment, a first venting groove 51 is formed between the top wall 11 of the liquid storage chamber 10 and the liquid storage component 2, a second venting groove 52 is formed between the liquid storage component 2 and the side wall 13, and a third venting groove 53 is formed between the bottom wall 13 and the liquid storage component 2; moreover, the first venting groove 51 is connected to the air guide pipe 4 and the air outlet 111, so the gas discharged from the surface of the liquid storage component 2, as well as the gas in the air guide pipe, can be discharged directly from the outer surface of the liquid storage component 2. The gas can be discharged through the first exhaust channel 51 to the exhaust port 111, and then discharged from the liquid storage component. The second exhaust channel 52 is connected to the first exhaust channel 51, so the gas discharged from the surface of the liquid storage component can pass through the connection between the second exhaust channel 52 and the first exhaust channel 51, along the second exhaust channel 52 to the first exhaust channel 51, and finally be discharged through the exhaust port 111. The third exhaust channel 53 is connected to the second exhaust channel 52, so the gas on the surface of the liquid storage component 2 can also pass through the third exhaust channel 53, the second exhaust channel 52, and the first exhaust channel 51 in sequence, and finally be discharged outward through the exhaust port 111. The first exhaust channel 51 is formed between the top wall 11 and the liquid storage component 2, that is, there is a gap between the liquid storage component 2 and the top wall 11; the same reasoning applies to the formation of the third exhaust channel 53 between the bottom wall 12 and the liquid storage component 2. In this structure, the end face of the liquid storage component 2 near the top wall 11 can be vented through the first vent groove 51 at the top wall 11, and the end face of the liquid storage component 2 near the bottom wall 12 can also be vented through the third vent groove 53 provided at the bottom wall 12, thereby effectively increasing the area on the liquid storage component 2 for air to be discharged. Please refer to... Figure 4 As shown, Figure 4 The diagram also shows the exhaust of air from the liquid reservoir 2 along multiple paths, where the arrows indicate the exhaust directions, specifically including: exhaust along the direction of the first exhaust channel 51-exhaust port 111; exhaust along the direction of the second exhaust channel 52-first exhaust channel 51-exhaust port 111; and exhaust along the direction of the third exhaust channel 53-second exhaust channel 52-first exhaust channel 51-exhaust port.

[0050] In some embodiments, the outer surface of the liquid storage component 2 may be provided with a recess 22, and the gap between the recess 22 and the side wall 13 forms a second venting groove 52. The second venting groove 52 is connected to the first venting groove 51 and the third venting groove 53. That is, a clearance structure can be provided on the liquid storage component 2, which is the recess 22. Due to the presence of the recess 22, a gap is formed between the outer surface of the liquid storage component 2 located at the recess 22 and the side wall 13 of the liquid storage tank 10. Due to the presence of this gap, air can circulate, that is, the second venting groove 52 is formed through the gap. The air in the liquid storage component 2 is discharged through the second venting groove 52, and then can be discharged from the first venting groove 51 along the communication relationship between the second venting groove 52 and the first venting groove 51, and finally discharged outward through the air outlet 111 connected to the first venting groove 51.

[0051] In some embodiments, to allow communication between the second venting groove 52 and the first venting groove 51 and the third venting groove 53, the recess 22 can axially extend through both ends of the liquid storage component 2. Since the recess 22 extends through both ends of the liquid storage component 2, the corresponding second venting groove 52 can simultaneously connect to the first venting groove 51 provided on the top wall 11 and the third venting groove 53 provided on the bottom wall 12. The shape of the recess 22 can be a straight line distributed axially or a curved shape with multiple bends. By providing the recess 22, the surface area of ​​the liquid storage component 2 can be objectively increased, thereby enhancing the venting performance of the liquid storage component 2 and reducing the leakage of the aerosol matrix. The number of recesses 22 can be greater than or equal to two, with each recess 22 spaced circumferentially along the liquid storage component 2. The more recesses 22 provided, the larger the surface area of ​​the liquid storage component 2 and the stronger the venting performance. Considering the venting performance and the liquid storage capacity of the liquid storage component 2, the recess 22 can include two recesses, which can be symmetrically arranged on the surface of the liquid storage component 2 along the axis of the mounting through hole 21.

[0052] In some embodiments, in order to form a first venting groove 51, a first protrusion 112 may be provided on the surface of the top wall 11 near the bottom wall 12. The first protrusion 112 has a first notch 113 that penetrates itself. The first protrusion 112 can abut against the end face of the liquid storage member 2, so that a first venting groove 51 is formed between the top wall 11 and the liquid storage member 2, and the first venting groove 51 is connected to the air outlet 111 through the first notch 113. The purpose of providing the first protrusion 112 is to form a gap between the liquid storage component 2 and the top wall 11. This gap, namely the first exhaust groove 51, is connected to the air outlet 111 to facilitate air discharge. The first protrusion 112 is provided on the inner wall of the top wall 11 facing the liquid storage component 2. The first protrusion 112 can restrict the position of the liquid storage component 2, so that there is space between the top of the liquid storage component 2 and the part of the lower surface of the top wall 11 where the first protrusion 112 is not provided. Then, the first protrusion 112 also has a first notch 113 that penetrates itself. The first notch 113 is connected to the air outlet 111, thereby forming the space between the top of the liquid storage component 2 and the top wall 11, namely the first exhaust groove 51, which is connected to the air outlet 111 through the first notch 113.

[0053] In addition, the gap between the liquid storage component 2 and the top wall 11 can also be achieved by setting the size of the liquid storage component 2. For example, the axial dimension of the liquid storage component 2 can be set to be smaller than the axial inner diameter of the liquid storage tank 10. In this way, the liquid storage component 2 will naturally form a gap with at least one of the top wall 11 and / or bottom wall 12 of the liquid storage tank 10, thereby forming the required first venting groove 51 and / or third venting groove 53. In other words, the first protrusion 112 provided on the top wall 11 in this embodiment is only one means of forming the first venting groove 51. Those skilled in the art can also use other means to form the first venting groove 51 between the liquid storage component 2 and the top wall 11.

[0054] In some embodiments, please refer to Figure 8The specific form of the first exhaust groove 51 formed on the top wall 11 can be as follows: the first protrusion 112 includes a plurality of first arcuate flanges 114, a plurality of second arcuate flanges 115 and a connecting flange 116. Each first arcuate flange 114 is arranged at intervals around the air outlet 111, each second arcuate flange 115 is arranged at intervals around the first arcuate flange 114, and the connecting flange 116 connects to adjacent first arcuate flanges 114 and second arcuate flanges 115; the interval between adjacent first arcuate flanges 114 and the interval between adjacent second arcuate flanges 115 form a first notch 113. The first protrusion 112 may include a single layer or multiple layers of arc-shaped flanges surrounding the air outlet 111. The arc-shaped flanges 114 and 115 are arranged sequentially from the direction closest to the air outlet 111 to the direction furthest from the air outlet 111. An interval is provided between adjacent first arc-shaped flanges 114 and adjacent second arc-shaped flanges 115, which is the first notch 113. Due to the provision of the first arc-shaped flanges 114 and the second arc-shaped flanges 115, direct contact between the liquid storage component 2 and the top wall 11 is prevented, thereby forming a gap between the liquid storage component 2 and the top wall 11. Then, through the interval between adjacent first arc-shaped flanges 114 and the interval between adjacent second arc-shaped flanges 115 as the first notch 113, the gap between the liquid storage component 2 and the top wall 11 and the air outlet 111 can be connected to form the first exhaust groove 51. In this case, the air in the liquid reservoir 2 can eventually be discharged outward through the vent 111, which can prevent the air in the liquid reservoir 2 from expanding due to heat and squeezing the aerosol matrix outward, causing leakage. Setting the arc-shaped flange in multiple layers can increase the contact area with the liquid reservoir 2, reduce the local pressure, and prevent the liquid reservoir 2 from undergoing excessive deformation and blocking the vent 111.

[0055] Additionally, please refer to Figure 9 In addition to forming a first venting groove 51 on the top wall 11, a third venting groove 53 can also be formed on the bottom wall 12. Specifically, a second protrusion 122 is provided on the surface of the bottom wall 12 near the top wall 11. The second protrusion 122 has a second notch 123 that penetrates through it. The second protrusion 122 can abut against the end face of the liquid storage component 2, so that a third venting groove 53 is formed between the bottom wall 12 and the liquid storage component 2, and the third venting groove 53 and the second venting groove 52 are connected through the second notch 123. Similar to the first venting groove 51 formed on the top wall 11, the third venting groove 53 is formed between the upper surface of the bottom wall 12 and the liquid storage component 2. By providing the second protrusion 122 on the upper surface of the bottom wall 12, a gap, i.e., the third venting groove 53, is formed between the other parts of the bottom wall 12 except for the part with the second protrusion 122 and the liquid storage component 2. Then, the third venting groove 53 and the second venting groove 52 are connected through the second notch 123 on the second protrusion 122.

[0056] In some embodiments, the specific form of the third exhaust groove 53 formed on the bottom wall 12 can be: the second protrusion 122 includes a first rib 124 surrounding the air inlet 121 and a plurality of second ribs 125 arranged alternately, and a second notch 123 is provided on the surface of the first rib 124 and the second rib 125 near the top wall 11 to connect the spaces formed by the separation of each first rib 124 and the second rib 125. The second protrusion 122 may include multiple staggered ribs, namely a first rib 124 surrounding the air inlet 121 and staggered second ribs 125; the second ribs 125 may be staggered horizontally and vertically or in a diamond pattern; the first ribs 124 and the second ribs 125 together enclose multiple separated spaces, and the tops of the first ribs 124 and the second ribs 125 restrict the contact between the liquid storage component 2 and the bottom of the separated spaces, so that each space can serve as a space where air can pass between the liquid storage component 2 and the bottom wall 12; then, in order to connect the spaces, each first rib 124 and the second rib 125 is provided with a second notch 123, wherein the second notch 123 is formed on the surface of the first rib 124 and the second rib 125, and with the presence of the second notch 123, the corresponding adjacent spaces are connected, thereby connecting all the spaces to form the third exhaust groove 53. In this case, the air in the liquid storage device 2 can be discharged outward along the third exhaust groove 53, the second exhaust groove 52, the first exhaust groove 51 and the air outlet 111. This can also prevent the air in the liquid storage device 2 from being heated and expanding, which would squeeze the aerosol matrix outward and cause leakage.

[0057] According to the liquid storage component in this application embodiment, since the assembly through hole 21 formed by the liquid storage component 2 is provided with a vent pipe 4 having a vent hole 42, the air in the liquid storage component 2 can enter the vent pipe 4 through the vent hole 42 and then be discharged from the liquid storage component along the vent 111. This greatly reduces the phenomenon of air expansion and compression of the aerosol matrix in the liquid storage component 2, thereby reducing the leakage of the aerosol matrix and improving the user experience.

[0058] In addition, an atomizing device is also provided in the embodiments of this application, please refer to... Figure 1 and Figure 2 The system includes a power supply component 6 and a liquid storage component as described in this embodiment. The power supply component 6 is fixedly mounted on the housing 1 and is used to supply power to the heating component 3. Based on the power supply component 6, the heating component 3 can convert electrical energy into heat energy to heat the aerosol matrix and generate aerosol. The power supply component 6 can be a disposable battery, or it can be configured as a detachable structure for easy replacement and charging. A charging interface can also be provided on the housing 1 to charge the power supply component 6.

[0059] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
