Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to a leak-proof atomization device. Background Technology

[0002] Nebulizers are favored by users due to their portability and ease of use. Currently, large-capacity nebulizers generally include a liquid reservoir, a coil, a control circuit board, and a rechargeable battery. The coil heats the atomizing matrix, causing at least a portion of the active substances in the matrix to volatilize and produce an aerosol. In existing large-capacity nebulizers, the atomizing matrix is ​​stored in a liquid reservoir, which is assembled with a support frame and silicone components. The support frame, made of plastic, forms the reservoir structure, while the silicone components provide a seal. An interference fit between the silicone and the inner wall of the liquid reservoir, also made of plastic, ensures a tight seal.

[0003] However, existing plastic liquid storage tanks and supports are typically made of polyethylene terephthalate-1,4-cyclohexanediol, a non-crystalline copolyester (PCTG). This material is prone to deformation and expansion at temperatures of 60 degrees Celsius or higher. In existing atomizing equipment structures, this results in reduced interference between the silicone components and the liquid storage tank, leading to seal failure and leakage. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this application is to provide a leak-proof atomizing device, resolving the technical problem of leakage caused by the deformation and outward expansion of the support frame in existing atomizing devices due to high temperatures. The details are described below.

[0005] This embodiment provides a leak-proof atomizing device, including:

[0006] The liquid storage tank has a storage space, and an atomizing tube is installed in the storage space.

[0007] A support frame is installed in a storage space to form a liquid storage tank structure. The support frame includes a tank body seal for sealing the liquid storage tank. The liquid storage tank is provided with an atomizing tube in the storage space. One end of the atomizing tube is connected to a nozzle that extends out of the liquid storage tank, and the other end is positioned and sealed on the tank body seal. At least one elastic member is clamped between the tank body seal and the support frame.

[0008] When the support does not deform, the elastic potential energy of the elastic element is confined between the support and the outer shell of the liquid storage tank; when the support deforms, the elastic potential energy of the elastic element expands the tank seal as the support deforms, so that the tank seal fits tightly against the outer shell.

[0009] In the sealing structure of the bracket, an atomizing core is provided in the atomizing tube, and the bracket includes an outer mounting edge for clamping and fixing the elastic element. The bracket forms a first sealing groove, a second sealing groove and a third sealing groove within the outer mounting edge.

[0010] In the sealing structure, the chamber sealing component includes an atomizing core sealing ring, an atomizing tube sealing ring, a sealing body, and a sealing outer edge. The atomizing core is fixed in the first sealing groove and sealed by the atomizing core sealing ring; the atomizing tube is fixed in the second sealing groove and sealed by the atomizing tube sealing ring; the sealing body is placed in the third sealing groove, and the sealing outer edge surrounds the elastic element and forms a deformation space for the elastic element between the outer edge and the inner wall of the liquid storage chamber.

[0011] Among them, the elastic element uses a metal material or a material that is elastic and whose elasticity is not affected by temperature.

[0012] In one embodiment, the elastic element is a metal elastic element, which includes a potential energy gap and is shaped to match the outer edge of the mounting. In an unconstrained state, the metal elastic element expands the potential energy gap. When the elastic element is assembled in the liquid storage tank and is in a constrained state, the potential energy gap of the elastic element closes and generates outward tension on the outer edge of the seal.

[0013] In one embodiment, the elastic element includes a first elastic element and a second elastic element, both of which are snapped and fixed to the outside of the mounting outer edge, and the first potential energy gap of the first elastic element and the second potential energy gap of the second elastic element are staggered.

[0014] In one embodiment, a connecting hole is formed in the first sealing groove of the support, and a gas guiding channel is formed below the support of the liquid storage tank. The gas guiding channel is aligned with the connecting hole, and an atomizing space is formed in the atomizing core. The atomizing tube includes a mixing space, and the atomizing space is connected to the gas guiding channel through the connecting hole. The mixing space is connected to the atomizing space.

[0015] In one embodiment, the atomizing core seal is installed in the atomizing core sealing ring and aligned with the connecting hole of the bracket. The tube wall of the atomizing tube is supported on the atomizing tube sealing ring. Multiple sealing ribs are provided on the outer edge of the seal. The outer edge of the chamber seal is sealed by interference fit between the sealing ribs and the inner wall of the liquid storage chamber to achieve sealing.

[0016] In one embodiment, a battery compartment and a storage compartment are provided below the bracket. The battery compartment houses the power supply component, and the storage compartment houses the first liquid suction component and the airway sealing component. A second liquid suction component is provided around the power supply component.

[0017] The atomizing device also includes a control circuit board, the atomizing core is electrically connected to the control circuit board, the control circuit board is mounted on the base, the outer shell of the liquid storage tank is assembled with the base, and at least one of the base and the outer shell is provided with a magnetic attachment for attracting the main unit.

[0018] In one embodiment, the base has at least one air adjustment hole, and the base includes an air adjustment slider and a base seal. The air adjustment slider is used to cover and adjust the size of the air adjustment hole, and the air adjustment slider is installed in the base through the base seal.

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] This application incorporates an elastic element, such as a metal elastic element or other elastic element whose elasticity is unaffected by temperature, into the liquid storage chamber of the atomizing device. When the support does not deform, the elastic potential energy of the elastic element is constrained between the support and the outer shell of the liquid storage chamber. When the support deforms, the elastic potential energy of the elastic element expands the chamber seal along with the deformation of the support, causing the chamber seal to fit tightly against the outer shell, thereby adaptively adjusting the sealing interference of the chamber seal to prevent leakage.

"Multiple" means two or more. Unless otherwise specified, "connection" or "linkage" in this application includes both direct and indirect connections (linkages).

[0044] Please refer to this as well. Figures 1 to 2 The diagram shows a perspective view and an exploded view of the leak-proof atomizing device in this embodiment, including its internal hardware structure and external structure.

[0045] like Figure 1 as well as Figure 2 As shown, the leak-proof atomizing device includes a liquid storage tank 1, a support 2, a tank body seal 4, and an atomizing tube 3. The tank body seal 4 is made of silicone. The liquid storage tank 1 is sealed by the interference fit between the silicone and the inner wall of the liquid storage tank.

[0046] The liquid storage chamber 1 of the atomizing device, which stores the atomizing matrix, includes a shell and a base 8. The shell 1 includes a shell body 10 and a connecting shell 13. The liquid storage chamber forms a storage space E inside. The support 2 is installed in the storage space E and seals and separates the storage space, forming a liquid storage chamber structure that includes a liquid storage space, an electrical control space, and an atomization channel.

[0047] The atomizing device forms a battery compartment and a storage compartment in the electrical control space below the support 2. The battery compartment houses a power supply component, such as a rechargeable battery 5. The storage compartment contains a first liquid-absorbing component 61 and an airway sealing component 62. Below the storage compartment, surrounding the air guide channel and the rechargeable battery 5, a second liquid-absorbing component 63 is positioned. In this embodiment, the first liquid-absorbing component 61 and the second liquid-absorbing component 63 are used to absorb the atomizing matrix leaking from the liquid storage compartment 1. The first liquid-absorbing component 61 and the second liquid-absorbing component 63 are liquid-absorbing cotton blocks.

[0048] The base 8 includes a base seal 82 and an air adjustment slider 85. The base seal 82 is a silicone part for fixation, on which a control circuit board 7 is mounted. The control circuit board 7 includes a processor, a charging management unit, a power output circuit, etc., and is connected to corresponding sensors. The control circuit board 7 is connected to the power supply interface 131.

[0049] The base 8 has multiple clips on its periphery, such as clip 81. The outer shell of the liquid storage tank is assembled with the clips of the base 8 to form the complete unit. Figure 1 As shown, at least one of the base 8 and the connecting housing 13 is provided with a magnetic element for engaging with the host. In this embodiment, the base 8 is provided with a first magnetic element 134, and the connecting housing 13 is provided with a second magnetic element 135 above it, for easier and more stable engagement with the connected host.

[0050] Please refer to this as well. Figure 3The atomizing tube 3 is used to seal the atomizing matrix, so that the atomizing matrix can only flow into the internal liquid storage cotton 31 from the small liquid inlet at the bottom. The liquid storage cotton 31 buffers the atomizing matrix. The atomizing matrix stored in the liquid storage chamber 1 flows into the liquid storage cotton 31 through the small hole of the atomizing tube 3, and after buffering, it is supplied to the heating element of the atomizing core 35 of the atomizing tube 3.

[0051] The atomizing tube 3 passes through the storage space of the liquid storage chamber, and after being sealed at the top by the first seal 32, it extends out of the liquid storage chamber 1 and connects to the nozzle 5. The other end of the atomizing tube 3 is positioned and sealed on the chamber body seal 4. The chamber body seal 4 is positioned on the bracket 2, and at least one elastic member in a constrained state is provided between the chamber body seal 4 and the bracket 2.

[0052] A mixing space B is provided in the atomizing tube 3, and an atomizing core 35 is provided at the bottom of the atomizing tube 3. The atomizing core 35 is electrically connected to the control circuit board 7 in the base. An atomizing space A is formed in the atomizing core 35, which is connected to the mixing space B so that the atomized aerosol is mixed and discharged from the exhaust port of the mouthpiece 5. When the atomizing device is not in use, a mouthpiece sealing plug 52 for dust prevention and leakage prevention is plugged into the exhaust port of the mouthpiece 5.

[0053] After the atomizing device is assembled, when the support 2 does not deform, the elastic potential energy of the elastic element 9 is constrained between the support 2 and the outer shell of the liquid storage chamber. When the support deforms, the elastic potential energy of the elastic element 9 expands the chamber seal 4 with the deformation of the support 2, so that the chamber seal 4 follows the deformation and keeps tightly fitted to the outer shell, so as to adaptively adjust the sealing interference of the chamber seal 4 to prevent leakage.

[0054] Please refer to this as well. Figure 4 as well as Figure 6 In the sealing structure of the bracket and the chamber seal, the bracket 2 includes a bracket body constructed as an inverted bowl, with an assembly structure for the chamber seal provided on the bottom of the bowl. The outermost periphery of the bracket 2 includes an outer mounting edge 25 for clamping the elastic element and a mounting shoulder 27 for mating with the deformation space formed by the inner wall of the liquid storage chamber 1 for the elastic element 9. The bracket 2 forms a first sealing groove 22, a second sealing groove 23, and a third sealing groove 24 inside the mounting outer edge 25. The third sealing groove 24 is separated from the second sealing groove 23 by a separating ring 26. The third sealing groove 24 is adjacent to the mounting outer edge 25.

[0055] The bracket 2 has a connecting hole 21 in the first sealing groove 22, which is part of the air guide channel.

[0056] Please refer to Figure 7 The chamber seal 4 includes an atomizing core sealing ring 42, an atomizing tube sealing ring 44, a protruding irregular sealing body 46, and a sealing outer edge 47. During assembly, the multi-layer sealing structure of the chamber seal 4 is housed within multiple grooves in the bracket 2. Please refer to the attached diagram. Figure 4The atomizing core 35 of the atomizing tube 3 is aligned with the connecting hole 21 and is pressed and sealed in the first sealing groove 22 by the atomizing core sealing ring 42. The atomizing tube end surrounding the atomizing core 35 is fixed in the second sealing groove 23 and sealed by the atomizing tube sealing ring 44. The sealing body 46 is placed in the third sealing groove 24, the outer sealing edge 47 is supported on the mounting shoulder 27 and surrounds the elastic member 9, and a deformation space for the elastic member 9 is formed between the mounting outer edge 25 and the inner wall of the liquid storage tank.

[0057] Multiple sealing ribs, such as sealing rib 471, are provided on the outer periphery of the sealing outer edge 47. The sealing outer edge 47 of the chamber seal 4 is reinforced with the inner wall of the liquid storage chamber through the sealing ribs to ensure the sealing performance.

[0058] like Figure 3 As shown, the liquid storage chamber 1 forms an air guide channel C below the support 2. The air guide channel C is connected upward to the connecting hole 21 of the support 2 to provide atomizing airflow to the atomizing core 35.

[0059] In this embodiment, the elastic element is made of metal or a material that is elastic and whose elasticity is not affected by temperature, so that at high temperatures, the elastic element 9 follows the deformation of the bracket 2 to push the chamber seal 4 to fit tightly against the inner wall to provide elasticity that ensures sealing.

[0060] like Figure 9 As shown, in one alternative embodiment of the elastic element, the elastic element 9 is a square metal elastic element. The shape of the elastic element 9 matches the mounting outer edge 25, therefore other shapes can be used. The metal elastic element 9 includes a potential energy gap 91. Figure 9 In the unconstrained state shown, the metal elastic element expands the potential energy gap 91, at which point the potential energy gap 91 has a relatively large spacing. Figure 8 When the elastic element 9 shown is assembled in the liquid storage tank and is in a constrained state, the potential energy gap of the elastic element 9 closes and generates an outward tension on the outer edge 47 of the seal towards the inner wall of the liquid storage tank, so that the interference between the tank body seal 4 and the inner wall of the liquid storage tank remains at the initial design value, ensuring the sealing performance.

[0061] The number of elastic elements can be set to one or more, depending on the actual material of the atomizing device bracket 2. For example... Figure 8 In the illustrated embodiment, two elastic elements 9 are used. The elastic element 9 includes a first elastic element 90 and a second elastic element 95. Both the first elastic element 90 and the second elastic element 95 are clamped and fixed to the outside of the mounting outer edge 25. The first potential energy gap 901 of the first elastic element 90 and the second potential energy gap 951 of the second elastic element 95 are staggered to evenly distribute the outward tension.

[0062] Please refer to Figure 5When the atomizing core 35 generates aerosol in the atomization space A, the airflow speed in the air guide channel C can be changed by moving the air adjustment slider 85, thereby improving the user experience.

[0063] exist Figure 5 In the structure of the base seal 82 shown, the base seal 82 is provided with a groove 821 for sliding the air regulating slider 85, and has a first air guide hole 823 and a second air guide hole 824 of different sizes. After the air passage sealing plug 87 of the air guide channel C is pulled out, the air flow can be guided by air guide holes of different sizes by changing the position of the air regulating slider 85.

[0064] The above description, in conjunction with specific implementation methods, provides a further detailed explanation of the embodiments of this application. It should not be construed that the specific implementation of this application is limited to these descriptions. In the above embodiments, the connection relationships mentioned can be direct connections, and in some cases, indirect connections, such as those involving switches or relays. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications should be considered within the scope of protection of this application.
