The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0028] Please see the attached Figure 1 ~Attached Figure 8 As shown, an embodiment of the present application provides a nebulizer, comprising: an outer liquid tank 1, an inner liquid tank 2 and an atomization tank 3, a liquid locking component 4 for guiding the aerosol medium from the outer liquid tank 1 to the inner liquid tank 2 is provided between the outer liquid tank 1 and the inner liquid tank 2, an atomization core assembly 100 and a liquid absorption component 5 for guiding the aerosol medium from the inner liquid tank 2 to the atomization core assembly 100 are provided in the atomization tank 3, and the atomization core assembly 100 is arranged in the liquid absorption component 5. The present application is provided with multiple liquid tanks, which not only have a large liquid storage capacity, but also disperse the hydraulic pressure, so that the internal hydraulic pressure of the outer liquid tank 1 and the inner liquid tank 2 is greatly reduced, thereby avoiding leakage. At the same time, the circulation of the aerosol matrix between the outer liquid tank 1 and the inner liquid tank 2 is guided by the liquid locking component 4. The liquid locking component 4 can effectively slow down the flow rate of the aerosol matrix and reduce the hydraulic pressure of the inner liquid tank 2 by adjusting the density change. The inner liquid tank 2 guides the aerosol matrix into the atomization core assembly 100 through the guiding effect of the liquid absorption component 5, controls the liquid inlet speed, and the liquid absorption component 5 has a strong liquid locking effect to prevent leakage during suction.
[0029] As attached Figure 2 To the attached Figure 5 As shown, the liquid-locking element 4 and the liquid-absorbing element 5 are further arranged in layers, and at least two layers are provided, and each layer has a different density. The layered arrangement facilitates the setting of different densities, thereby allowing the liquid-locking element 4 and the liquid-absorbing element 5 to guide the aerosol matrix in different directions, while also slowing the flow rate of the aerosol matrix, thereby preventing leakage or seepage during placement and aspiration.
[0030] As attached Figure 2 To the attached Figure 5 As shown, further, a liquid inlet 31 is provided between the inner liquid reservoir 2 and the atomization reservoir 3. The liquid absorbing member 5 includes a first layer 51, a second layer 52, and a third layer 53 stacked sequentially from bottom to top in a direction away from the liquid inlet 31. The density of the first layer 51 is less than that of the second layer 52, and the density of the second layer 52 is less than that of the third layer 53. The density within the liquid absorbing member 5 gradually increases from bottom to top, and the aerosol matrix moves along the layer with lower density toward the layer with higher density, that is, from bottom to top within the liquid absorbing member 5. Therefore, under the guidance of the liquid absorbing member 5, the aerosol matrix in the inner liquid reservoir 2 is sucked from the liquid inlet 31 and transported upward, so that the aerosol matrix enters the atomization core assembly 100 and forms an aerosol under the heating of the atomization core assembly 100. The liquid inlet speed is controlled, and the liquid absorbing member 5 has a strong liquid locking effect to prevent leakage during suction.
[0031] Furthermore, the nebulizer also includes an outer shell 6, an inner shell 7 arranged in the outer shell 6, a linkage 8 arranged in the inner shell 7, and a pull-out rod 81 detachably connected to the linkage 8. The gap between the outer shell 6 and the inner shell 7 forms the outer liquid tank 1, the inner liquid tank 2 is arranged in the inner shell 7, and the atomization tank 3 is arranged in the linkage 8. When the linkage 8 moves upward to the extreme position under the pull of the pull-out rod 81, the liquid inlet 31 leaks out. At this time, the pull-out rod 81 can be pulled out, so that the nebulizer is used. The liquid inlet 31 is arranged in a ring shape to facilitate the lower end of the liquid absorbing component 5 to be completely immersed in the aerosol matrix.
[0032] Furthermore, a fastener 56 is provided in the liquid absorbing member 5, and a gap 57 is formed between the liquid absorbing member 5 and the fastener 56. Even if aerosol matrix or condensed liquid leaks out, it is stored in the gap 57. At the same time, the collected aerosol matrix can be further absorbed by the liquid absorbing member 5, which is conducive to secondary absorption and atomization.
[0033] Furthermore, the shell 6 can also be set to be transparent or translucent to facilitate observation of the liquid amount in the external liquid tank 1. At the same time, fluorescent material can be placed in the external liquid tank 1 to make the atomizer full of dynamics when shaking, thereby improving the visual effect.
[0034] As attached Figure 2 To the attached Figure 4 As shown, further, the density of the first layer 51 is 0.03-0.05 g / cm 3 The density of the second layer 52 is 0.05-0.07 g / cm 3 The density of the third layer 53 is 0.07-0.09 g / cm 3 Each layer is set with a suitable density, and a suitable density difference is set between the two layers, so that the aerosol matrix moves from bottom to top under the guidance of the liquid absorbing component 5 and flows into the atomizing core assembly 100.
[0035] Furthermore, the absorbent member 5 is made of a mixture of PA and PP, and each layer has a different density by adjusting the mixing ratio of PA and PP. The density of the first layer 51 is 0.04 g / cm 3 The density of the second layer 52 is 0.06 g / cm 3 The density of the third layer 53 is 0.08 g / cm 3 The aerosol matrix is facilitated to move from bottom to top under the guidance of the liquid absorbing member 5.
[0036] As attached Figure 2 To the attached Figure 4As shown, the liquid absorbing member 5 further has a ventilation groove 54 connecting the liquid inlet 31 and the atomizer core assembly 100. This strengthens the ventilation function of the liquid absorbing member 5 and prevents the aerosol matrix from being unable to move upward due to insufficient ventilation of the liquid absorbing member 5, resulting in insufficient liquid supply to the atomizer core assembly 100, and further causing the atomizer core assembly 100 to burn out and become scorched.
[0037] As attached Figure 2 To the attached Figure 4 As shown, the liquid absorbing member 5 further includes an inner hole 55 for accommodating the atomizer core assembly 100. The opening at one end of the ventilation groove 54 is located on the bottom surface of the first layer 51, and the opening at the other end of the ventilation groove 54 is located on the second layer 52 and on the sidewall of the inner hole 55. The atomizer core assembly 100 is disposed within the second layer 52, and the opening at the other end of the ventilation groove 54 is located at the atomizer core assembly 100, further enhancing the ventilation function of the liquid absorbing member 5 and preventing the atomizer core assembly 100 from burning out and causing scorching.
[0038] Furthermore, the atomizer core assembly 100 is arranged in the second layer 52, and the density of the third layer 53 is greater than that of the second layer 52. Therefore, the liquid absorption capacity of the third layer 53 is greater than that of the other two layers, which effectively prevents leakage. At the same time, the third layer 53 also has a liquid storage function. After the atomizer core assembly 100 absorbs the aerosol matrix in the second layer 52, the third layer 53 and the first layer 51 can both supply the aerosol matrix to the second layer 52. Liquid is supplied at both ends, further preventing the atomizer core assembly 100 from burning out and becoming burnt.
[0039] As attached Figure 2 To the attached Figure 4 As shown, further, the diameter of the ventilation groove 54 is 0.2-0.4 mm, which ensures that the liquid absorbing member 5 has a strong ventilation function while not affecting the guiding function of the liquid absorbing member 5 on the aerosol matrix.
[0040] Furthermore, taking the diameter of the wicking element 5 as an example, which is 9-10 mm, the diameter of the inner hole 55 is 5 mm, and the diameter of the ventilation groove 54 is 0.3 mm, thereby ensuring that the wicking element 5 has a strong ventilation effect, while not affecting the guiding effect of the wicking element 5 on the aerosol matrix.
[0041] As attached Figure 2 To the attached Figure 5As shown, the liquid locking member 4 further includes an outer layer 41 on the side close to the outer liquid tank 1 and an inner layer 42 on the side close to the inner liquid tank 2. The density of the outer layer 41 is lower than that of the inner layer 42. The density in the liquid locking member 4 gradually increases from left to right, and the aerosol matrix moves along the layer with lower density toward the layer with higher density, that is, from left to right in the liquid locking member 4. Therefore, under the guidance of the liquid locking member 4, the aerosol matrix is drawn from the outer liquid tank 1 and transported to the inner liquid tank 2, reducing the backflow of the aerosol matrix, that is, reducing the flow rate of the aerosol matrix from the inner liquid tank 2 toward the outer liquid tank 1, effectively slowing down the flow rate of the aerosol matrix and reducing the hydraulic pressure of the inner liquid tank 2, thereby preventing leakage during suction.
[0042] As attached Figure 2 To the attached Figure 5 As shown, further, the density of the outer layer 41 is 0.05-0.07 g / cm 3 The density of the inner layer 42 is 0.07-0.09 g / cm 3 Each layer is set with a suitable density, and a suitable density difference is set between the two layers, so that the aerosol matrix can move from left to right under the guidance of the liquid lock member 4, effectively slowing down the flow rate of the aerosol matrix and reducing the hydraulic pressure of the inner liquid tank 2 to prevent leakage during suction.
[0043] Furthermore, the liquid locking component 4 is prepared by mixing PA and PET, and by adjusting the mixing ratio of PA and PET so that each layer has a different density, the liquid locking component 4 has a function similar to a one-way valve, that is, the aerosol matrix flows from the outer liquid tank 1 to the inner liquid tank 2 in one direction.
[0044] Furthermore, the density of the outer layer 41 is 0.06 g / cm 3 The density of the inner layer 42 is 0.08 g / cm 3 . It is convenient for the aerosol matrix to move from left to right under the guidance of the liquid locking member 4.
[0045] Please see the attached Figure 2 To the attached Figure 8As shown, based on the above-mentioned atomizer, an embodiment of the present application also provides an aerosol generating device, including the atomizer. The present application is provided with multiple liquid tanks, which not only have a large liquid storage capacity, but also disperse the hydraulic pressure, so that the internal hydraulic pressure of the outer liquid tank 1 and the inner liquid tank 2 is greatly reduced to avoid leakage. At the same time, the circulation of the aerosol matrix between the outer liquid tank 1 and the inner liquid tank 2 is guided by the liquid locking part 4. The liquid locking part 4 can effectively slow down the flow rate of the aerosol matrix and reduce the hydraulic pressure of the inner liquid tank 2 by adjusting the change in density. The inner liquid tank 2 guides the aerosol matrix into the atomizing core assembly 100 through the guiding effect of the liquid absorbing part 5, controls the liquid inlet speed, and the liquid absorbing part 5 has a strong liquid locking effect to prevent leakage during suction.
[0046] Furthermore, the aerosol generating device also includes a control panel 9 and a display screen 90 arranged on the control panel 9, and the display screen 90 is electrically connected to the control panel 9. The inner shell 7 is also provided with an installation cavity 71 located on one side of the inner liquid tank 2, and the inner wall of the installation cavity 71 is symmetrically provided with a card slot 72, and the control panel 9 is clamped in the card slot 72. At the same time, the opening of the installation cavity 71 is also clamped with a protective cover 73 for fixing the control panel 9.
[0047] Furthermore, the aerosol generating device also includes a microphone assembly, which includes a microphone 91 and a microphone silica gel 92 mounted on the microphone 91. The microphone 91 is electrically connected to the control panel 9. The lower end of the shell 6 is provided with a plug 93 and an air inlet 94 located in the microphone silica gel 92. The air inlet 94 is arranged on one side of the plug 93. At the same time, a microphone air path 95 is also provided in the microphone silica gel 92. The microphone air path 95 is "S"-shaped or "bow"-shaped. A microphone liquid absorbent 96 is provided in the microphone air path 95. The microphone liquid absorbent 96 is arranged at the lower end of the microphone 91.
