Description

Technical Field

[0002] The nebulizer is the core component of the atomization device, usually including a liquid storage chamber and an atomization assembly connected by fluid. The liquid storage chamber is used to provide the atomization matrix to the atomization assembly, and the atomization assembly is used to atomize the atomization matrix into an aerosol.

[0003] Currently, the atomizer assembly is typically placed within a liquid storage chamber, allowing the atomized matrix to directly enter the atomizer assembly and be atomized. If the liquid storage chamber has a small amount of liquid, the atomizer device may have a short service life, or the atomizer may need to be frequently replaced to extend the device's service life, impacting users. If the liquid storage chamber has a large amount of liquid, its prolonged connection to the atomizer assembly can easily cause leakage or contamination of the atomized matrix, seriously impacting the user experience.

Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0035] Existing products require frequent replenishment of the aerosol matrix into the liquid storage chamber.

[0036] In the present application, a liquid guide tube is provided to control the maximum liquid storage level of the liquid storage chamber, thereby ensuring the supply of the atomizer core to the atomizer matrix in the liquid storage chamber. While preventing the atomizer core from leaking or being contaminated by the atomizer matrix, it can effectively prevent the atomizer core from sticking, thereby greatly improving the user experience.

[0037] Please refer to Figures 1 to 4 In one embodiment, an atomizer is provided, comprising: a shell 1, the shell 1 comprising a top wall 11 and a side wall 12 connected to the top wall 11; a bracket 2, the bracket 2 being arranged in the shell 1 and enclosing with at least part of the structure of the shell 1 to form a liquid storage chamber 13, the liquid storage chamber 13 being used to accommodate an atomized matrix; the bracket 2 being provided with a liquid guide tube 21, the liquid guide tube 21 being used to supply the atomized matrix to the liquid storage chamber 13, at least part of the structure of the liquid guide tube 21 extending toward the top wall 11, a first liquid guide port 211 being provided on a side of the liquid guide tube 21 close to the top wall 11, the first liquid guide port 211 being used to connect the liquid guide tube 21 and the liquid storage chamber 13; Atomizer assembly 4 is disposed within the housing 1. The atomizer assembly 4 includes an atomizer tube 41 and an atomizer core 42 disposed within the atomizer tube 41. The atomizer tube 41 is provided with a second liquid guide port 411. The second liquid guide port 411 is used to connect the liquid storage chamber 13 with the atomizer core 42. The atomizer core 42 is used to atomize the atomized matrix into an aerosol. The first liquid guide port 211 has a first edge that is at the greatest distance from the top wall 11, and the spacing between the first edge and the top wall 11 is h1. The second liquid guide port 411 has a second edge that is at the greatest distance from the top wall 11, and the spacing between the second edge and the top wall 11 is h2, satisfying the following: h2>h1. Specifically, the liquid storage chamber 13 is formed by enclosing the bracket 2, the top wall 11 of the housing 1, and at least a portion of the side wall 12.

[0038] In this embodiment, since the liquid guide tube 21 is provided with a first liquid guide port 211, the atomized matrix of the refill container 3 can be replenished into the liquid storage chamber 13 through the liquid guide tube 21, thereby realizing the replenishment of the atomized matrix. Since the atomization tube 41 is provided with a second liquid guide port 411, the atomized matrix of the liquid storage chamber 13 can be made to enter the atomization core 42, thereby realizing the atomization of the atomized matrix. More importantly, since the distance between the first edge of the first liquid guide port 211 and the top wall 11 is smaller than the distance between the second edge of the second liquid guide port 411 and the top wall 11, that is, the highest liquid storage level of the liquid storage chamber 13 is higher than the highest liquid inlet level of the atomization tube 41, thus, the supply of the atomized matrix in the atomization core 42 can be effectively guaranteed, and the problem of the atomization core 42 being stuck can be effectively prevented. At the same time, the liquid storage height of the liquid storage chamber 13 is increased, thereby appropriately reducing the number of times the atomized matrix is ​​replenished to the liquid storage chamber 13, which is conducive to improving the user experience. In addition, since the liquid guide tube 21 is provided, the liquid guide tube 21 can replenish liquid into the liquid storage chamber 13, which can, on the one hand, expand the total liquid storage capacity of the nebulizer; on the other hand, it can enable the liquid storage chamber 13 to store only an appropriate amount of atomized matrix, effectively avoiding the problem of leakage or atomized matrix contamination in the atomizing component 4 connected to the liquid storage chamber 13, which is conducive to further improving the user experience.

[0039] It is understandable that, when the cross-sectional area of ​​the liquid storage chamber 13 remains unchanged, the distance between the first edge and the top wall 11 determines the maximum amount of atomized matrix that the liquid storage chamber 13 can accommodate. Specifically, as the distance between the first edge and the top wall 11 decreases, the liquid storage height of the liquid storage chamber 13 gradually increases, so that the maximum amount of atomized matrix that the liquid storage chamber 13 can accommodate increases, so that the number of times the liquid storage chamber 13 is replenished can be effectively reduced. It should be noted that the first liquid guide port 211 can be a liquid guide hole opened in the wall of the liquid guide tube 21, or it can be a liquid guide groove opened in the wall of the liquid guide tube 21, which is not limited here, and those skilled in the art can adjust according to actual needs. It is understandable that when the first liquid guide port 211 is a liquid guide groove, the processing difficulty of the bracket 2 can be reduced. It should be noted that the embodiment of the present application does not limit the opening shape and the number of the second liquid guide ports 411. In one embodiment, there are at least two second liquid guide ports 411, and at least two second liquid guide ports 411 are arranged at intervals along the circumference of the atomizer tube 41, and the second liquid guide ports 411 are waist-shaped holes. In addition, in order to improve the structural strength of the atomizer tube 41, reinforcing ribs extending along the circumference of the atomizer tube 41 can also be provided in the second liquid guide ports 411.

[0040] Although the smaller the distance between the first edge and the top wall 11, the greater the relative liquid storage capacity of the liquid storage chamber 13, at the same time, the size of the first liquid guide port 211 will also decrease, and the rate at which the liquid guide tube 21 replenishes the atomized matrix will decrease. In one embodiment, the distance between the first edge and the top wall 11 satisfies: h1 ≥ 2 mm. In this way, while ensuring that the atomized matrix flows smoothly from the first liquid guide port 211 into the liquid storage chamber 13, the liquid storage height of the liquid storage chamber 13 can be increased as much as possible. According to tests, when the distance between the first edge and the top wall 11 satisfies: h1 = 3 mm, the smoothness of the atomized matrix flowing from the first liquid guide port 211 into the liquid storage chamber 13 can be further improved, thereby reducing the time required for rehydration, which is beneficial to improving the user experience.

[0041] In one embodiment, the first liquid guide port 211 is provided at the end of the liquid guide tube 21 (i.e., the first liquid guide port 211 is a liquid guide groove formed in the wall of the liquid guide tube 21), and the liquid guide tube 21 abuts against the top wall 11. This not only restricts the rate of liquid replenishment but also increases the space utilization of the liquid storage chamber 13, thereby further increasing the liquid storage capacity of the liquid storage chamber 13.

[0042] Please refer to Figure 5 In one embodiment, the liquid guiding tube 21 is provided with at least two first liquid guiding ports 211 , and the at least two first liquid guiding ports 211 are spaced apart along the circumference of the liquid guiding tube 21 .

[0043] In this embodiment, since at least two first liquid guide ports 211 are provided, that is, the atomized matrix can flow out from at least two first liquid guide ports 211, each first liquid guide port 211 is independent of each other and does not affect each other. When some of them experience slow flow or even blockage, the atomized matrix can still flow out smoothly, which is beneficial to improving the reliability of rehydration. In addition, in actual applications, rehydration is usually achieved by tilting or inverting the atomizer. When at least two first liquid guide ports 211 are arranged at intervals along the circumference of the liquid guide tube 21, while the atomized matrix flows into the liquid storage chamber 13 from some of the first liquid guide ports 211, the air in the liquid storage chamber 13 can flow out from the remaining first liquid guide ports 211; and / or while the atomized matrix flows into the liquid storage chamber 13 from some of the opening areas of the first liquid guide ports 211, the air in the liquid storage chamber 13 can flow out from the remaining opening areas of the first liquid guide ports 211, thereby achieving air pressure balance, accelerating the rehydration speed, further reducing the time required for rehydration, and further improving the user experience.

[0044] It should be noted that the embodiment of the present application does not limit the number of the first liquid guide ports 211, and those skilled in the art can adjust it according to actual needs. Figure 5 As shown, two first liquid guide ports 211 are provided, and the two first liquid guide ports 211 are spaced apart and symmetrically distributed along the circumference of the liquid guide tube 21. This not only improves the reliability of liquid infusion, but also, compared to providing more first liquid guide ports 211, the provision of two first liquid guide ports 211 can adaptably increase the opening area of ​​each first liquid guide port 211, thereby effectively preventing the formation of an oil film at the first liquid guide ports 211 that would block the flow of the atomized substrate.

[0045] In one embodiment, Figure 3 As shown, the nebulizer further includes a fluid replenishment container 3, which is disposed on a side of the bracket 2 facing away from the liquid storage chamber 13. The fluid replenishment container 3 is in fluid communication with a liquid conduit 21, so that the aerosolized matrix in the fluid replenishment container 3 enters the liquid storage chamber 13. Specifically, the fluid replenishment container 3 is in fluid communication with an end of the liquid conduit 21 facing away from the top wall 11.

[0046] In this embodiment, the provision of a fluid refill container 3, which is in fluid communication with the fluid conduit 21, allows the aerosolized matrix in the fluid refill container 3 to enter the fluid storage chamber 13, thereby replenishing the aerosolized matrix. It will be appreciated that the fluid storage volume of the fluid refill container 3 is typically greater than the fluid storage volume of the fluid storage chamber 13, thus enabling multiple refills of the fluid storage chamber 13.

[0047] It should be noted that the fluid refill container 3 has a first fluid conduit. By inserting the end of the fluid conduit 21 facing away from the top wall 11 into the first fluid conduit, communication between the fluid conduit 21 and the fluid refill container 3 is achieved, allowing the atomized matrix in the fluid refill container 3 to flow through the fluid conduit 21 into the liquid storage chamber 13, completing fluid refill. In addition, to improve the sealing effect between the fluid conduit 21 and the fluid refill container 3, a sealing member may be provided between the fluid conduit 21 and the first fluid conduit.

[0048] In one embodiment, Figure 3 As shown, the atomizer also includes: a sealing seat 5, which is arranged on a side of the bracket 2 close to the top wall 11, and the sealing seat 5 is provided with a first mounting groove 51; the top wall 11 is provided with a second mounting groove 111; the atomizing tube 41 has two ends arranged away from each other, one end of the atomizing tube 41 is sealedly connected to the first mounting groove 51, and the other end of the atomizing tube 41 is sealedly connected to the second mounting groove 111.

[0049] In one embodiment, the liquid storage chamber 13 is enclosed by the bracket 2 and the shell 1. Since the bracket 2 and the shell 1 are two independent structural members, there may be a problem of leakage at the connection between the two. Based on this, when a sealing seat 5 is provided on the side of the bracket 2 close to the top wall 11, the connection between the bracket 2 and the shell 1 can be sealed, thereby improving the sealing of the liquid storage chamber 13 and effectively avoiding leakage of the atomized matrix. In addition, since the corresponding positions of the sealing seat 5 and the top wall 11 are respectively provided with a first mounting groove 51 and a second mounting groove 111, by sealingly connecting the two ends of the atomizing tube 41 to the first mounting groove 51 and the second mounting groove 111, on the one hand, the installation and fixation of the atomizing assembly 4 can be achieved; on the other hand, the atomized matrix can enter the atomizing core 42 only from the second liquid guide port 411 of the atomizing tube 41, thereby effectively avoiding leakage of the atomized matrix from the first mounting groove 51 and the second mounting groove 111.

[0050] It should be noted that the material of the sealing seat 5 includes, but is not limited to, elastically deformable materials such as silicone and rubber. The elastic deformation of the sealing seat 5 effectively seals the connection between the bracket 2 and the housing 1, as well as the connection between the atomizer tube 41 and the sealing seat 5. In one embodiment, at least a portion of the top wall 11 protrudes toward the liquid storage chamber 13 to form an annular protrusion, which encloses a first mounting groove 51. To achieve a sealed connection between the first mounting groove 51 and the atomizer tube 41, a seal may be provided between the atomizer tube 41 and the annular protrusion.

[0051] In one embodiment, Figure 3 and Figure 6As shown, the atomizer further includes a liquid absorbing member 7, which is arranged on the side of the top wall 11 away from the liquid storage chamber 13; the top wall 11 is provided with a first ventilation hole 112; the liquid absorbing member 7 is provided with a second ventilation hole 71 at a corresponding position of the first ventilation hole 112; the aperture size of the first ventilation hole 112 is larger than the aperture size of the second ventilation hole 71.

[0052] When the atomizing core 42 atomizes the atomized matrix to produce an aerosol and flows out through the first vent 112, the absorbing member 7 can promptly absorb the condensate and / or leaked liquid mixed in the aerosol, preventing the condensate or leaked liquid from flowing out. In addition, since the aperture size of the first vent 112 is larger than the aperture size of the second vent 71, that is, a step structure can be formed between the first vent 112 and the second vent 71, the step structure can interfere with the condensate and / or leaked liquid droplets mixed in the aerosol, so that the condensate and / or leaked liquid droplets will be retained at the step structure. The continuously accumulated droplets can flow downward under the action of gravity, thereby returning to the atomizing core 42 or being absorbed by the absorbing member 7 in a timely manner, which can further prevent the condensate or leaked liquid from flowing out, thereby improving the user experience.

[0053] In one embodiment, Figure 3 and Figure 6 As shown, the atomizer further includes: a suction nozzle 6, which is arranged on the side of the top wall 11 away from the liquid storage chamber 13, and an accommodating chamber 113 is defined between the suction nozzle 6 and the top wall 11; and the liquid absorbing member 7 is interference-fitted in the accommodating chamber 113.

[0054] In this embodiment, by disposing the absorbent element 7 within the accommodating cavity 113 between the nozzle 6 and the top wall 11, condensed atomized matrix (i.e., condensed liquid) or leaked atomized matrix (i.e., leaked liquid) can be promptly absorbed, preventing the condensed liquid and leaked liquid from escaping with the aerosol and affecting the user experience. Furthermore, because the absorbent element 7 has an interference fit within the accommodating cavity 113, i.e., the absorbent element 7 is tightly attached to at least a portion of the nozzle 6 and the top wall 11, leakage of condensed liquid and / or leaked liquid can be effectively prevented.

[0055] It should be noted that, in order to facilitate replacement of the liquid-absorbing member 7, in one embodiment, the suction nozzle 6 is detachably connected to the top wall 11. Specifically, a receiving groove is provided on the side of the top wall 11 near the suction nozzle 6. The inner wall of the receiving groove and the outer wall of the suction nozzle 6 are respectively provided with a buckle and a slot. The buckle and the slot engage to achieve a detachable connection between the suction nozzle 6 and the top wall 11. The receiving groove and at least a portion of the suction nozzle 6 enclose a receiving cavity 113 for accommodating the liquid-absorbing member 7.

[0056] In one embodiment, Figure 4As shown, the atomizer tube 41 has a first air outlet 412 close to the top wall 11, and the first air outlet 412 is connected to the first air vent 112; the suction nozzle 6 is provided with an air outlet channel 61, and the air outlet channel 61 has a first air inlet 611 close to the liquid suction component 7, and the first air inlet 611 is connected to the second air vent 71; wherein, the center lines of the first air outlet 412, the first air vent 112, the second air vent 71 and the first air inlet 611 coincide with each other.

[0057] In this embodiment, since the first air outlet 412 of the atomizing tube 41 is connected to the first air vent 112, and the first air inlet 611 of the air outlet channel 61 of the suction nozzle 6 is connected to the second air vent 71, the atomizing tube 41 can be connected to the air outlet channel 61 of the suction nozzle 6, so that the aerosol generated by the atomizing core 42 can flow out of the suction nozzle 6 smoothly for user use. Since the center lines of the first air outlet 412, the first air vent 112, the second air vent 71 and the first air inlet 611 of the air outlet channel 61 of the atomizing tube 41 coincide, the resistance of the aerosol in the flow process can be reduced, the aerosol turbulence phenomenon can be reduced, and the aerosol can flow out more stably and evenly, which is conducive to improving the user experience. It should be noted that the orifice size of the first air outlet 412 of the atomizing tube 41 is the cross-sectional size of the atomizing tube 41 perpendicular to its axial direction.

[0058] In one embodiment, the aperture size of the first air outlet 412 is larger than the aperture size of the first air vent 112; and the aperture size of the second air vent 71 is larger than the aperture size of the first air inlet 611. In this way, a multi-step structure that contracts sequentially can be formed between the first air outlet 412 and the first air inlet 611. In this way, when droplets of condensed liquid and / or leaked liquid are mixed in the aerosol and flow out, each step structure can interfere with the droplets of condensed liquid and / or leaked liquid, causing the droplets of condensed liquid and / or leaked liquid to be retained at each step structure. The continuously accumulated droplets can flow downward under the action of gravity, thereby returning to the atomization core 42 or being promptly absorbed by the liquid absorbing member 7, which can further prevent the outflow of condensed liquid or leaked liquid, thereby improving the user experience.

[0059] It should be noted that the orifice shapes of the first air outlet 412, the first air vent 112, the second air vent 71, and the first air inlet 611 of the embodiment of the present application include but are not limited to circular, rectangular, triangular, elliptical, hexagonal, or other shapes. It is understandable that when the first air outlet 412, the first air vent 112, the second air vent 71, and the first air inlet 611 are all circular, the structure of the atomizer can be simplified and the difficulty of processing can be reduced. In this case, the orifice size refers to the orifice diameter. In addition, the embodiment of the present application does not limit the orifice size of the first air outlet 412, the first air vent 112, the second air vent 71, and the first air inlet 611, and those skilled in the art can adjust it according to actual needs.

[0060] Please refer to Figures 6 and 7 In one embodiment, a plurality of grooves 1121 are provided on the hole wall of the first vent hole 112, and the grooves 1121 are arranged at intervals along the circumference of the hole wall.

[0061] In this embodiment, a groove 1121 is provided on the wall of the first vent hole 112. The capillary action of the groove 1121 can break the oil film formed by the condensation liquid and / or leakage liquid in the first vent hole 112, which not only allows the aerosol to flow out smoothly for user use; but also effectively prevents the condensation liquid and / or leakage liquid from being mixed in the aerosol and flowing out, which is beneficial to improving the user experience.

[0062] It should be noted that the embodiment of the present application does not limit the number of grooves 1121, and those skilled in the art may adjust it according to actual needs. In one embodiment, there are four grooves 1121, and the four grooves 1121 are evenly spaced along the circumference of the hole wall, thereby further reducing the possibility of oil film formation.

[0063] In one embodiment, Figure 7 As shown, the width of groove 1121 along the circumferential direction of the hole wall is a, satisfying a ≥ 0.3 mm. This allows groove 1121 to exert a capillary action, effectively preventing the formation of an oil film; it also facilitates machining, further reducing the difficulty of machining housing 1. Testing has shown that when the width of groove 1121 along the circumferential direction of the hole wall is 0.5 mm, the machining difficulty of housing 1 can be further reduced while preventing the formation of an oil film.

[0064] It should be noted that the embodiment of the present application does not limit the radial length of the groove 1121 along the hole wall, and those skilled in the art can adjust it according to actual needs. In one embodiment, the radial length of the groove 1121 along the hole wall can be greater than or equal to 0.3 mm, and the groove 1121 should be within the projection range of the first mounting slot 51 along its axial direction.
