Description

Technical Field

[0001] The embodiments of this utility model relate to an atomizing device, and more particularly to a sealing element, a top cover assembly, and a fragrance diffuser. Background Technology

[0002] A nebulizer is an electronic product that uses heat to atomize liquid and produce a mist. Nebulizers are widely used in many fields, such as the medical and home applications. Currently, some nebulizers are also used in fragrance diffusers, where they atomize fragrance liquid and spray it out with an airflow to change the smell in the air and suppress odors.

[0003] Currently, most fragrance diffusers on the market have replaceable sachets. To facilitate sachet replacement, the top cover assembly is usually detachably connected to the main body. However, when assembling the top cover assembly with the main body, no additional seal is made between the two. This not only causes the atomizing medium inside the sachet to evaporate too quickly, but also, due to the poor sealing performance between the sachet and the top cover assembly, the airflow cannot be well concentrated after passing through the sachet when the fragrance is emitted, resulting in a poor mist output effect. Utility Model Content

[0004] The purpose of this utility model is to design a sealing element, a top cover assembly, and a fragrance diffuser. After the top cover assembly is assembled with the main body, it can ensure the sealing of the air outlet of the atomizing component while also ensuring the airflow strength after passing through the fragrance sac, so that the airflow can smoothly carry the atomizing medium out of the air outlet channel.

[0005] To achieve the above objectives, an embodiment of the present invention provides a sealing element, which is disposed on the upper cover of the fragrance diffuser and is used to elastically seal against the inner wall of the air outlet of the atomizing component when the upper cover is placed on the main body of the fragrance diffuser.

[0006] The sealing element is further provided with an exhaust channel along a preset axis, and the exhaust channel is connected to the air outlet of the atomizing component and each air outlet channel of the upper cover.

[0007] In addition, embodiments of this utility model also provide a cover assembly for a fragrance diffuser, the cover assembly comprising:

[0008] The top cover is placed on the main body of the fragrance diffuser along a preset axis and is used to position the atomizing component installed on the main body; the top cover has at least one air outlet channel;

[0009] The sealing element described above is disposed on the upper cover; wherein the exhaust passage of the sealing element is in communication with each of the air outlet passages.

[0010] In addition, embodiments of this utility model also provide a fragrance diffuser, comprising:

[0011] Main body; the main body is provided with a mounting groove along a preset axis for inserting the atomizing component;

[0012] The top cover assembly described above is placed on the main body and is used to fix the atomizing assembly in conjunction with the main body.

[0013] Compared with the prior art, the embodiments of this utility model have the following advantages: the sealing element is set on the top cover of the fragrance diffuser. By covering the main body of the fragrance diffuser with the top cover, the sealing element can elastically seal against the inner wall of the air outlet of the atomizing component. Furthermore, since the sealing element is provided with exhaust channels along a preset axis that are respectively connected to the air outlet and the air outlet channels of the top cover, it can be seen that the sealing element can not only achieve elastic sealing of the inner wall of the air outlet of the atomizing component, ensuring the sealing performance of the air outlet of the atomizing component, but also ensure the blowing force of the airflow after passing through the atomizing component through the exhaust channels on the sealing element, so that the atomizing medium can be smoothly carried out by the airflow from each air outlet channel, thereby achieving a good misting effect.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0019] Example 1

[0020] The first embodiment of this utility model relates to a sealing element, such as... Figure 1 and Figure 3 As shown, the sealing element 1 is provided on the upper cover 2 of the fragrance diffuser. The sealing element 1 is used to elastically seal the inner wall of the air outlet of the air outlet end 101 of the atomizing component when the upper cover 2 is placed on the main body 3 of the fragrance diffuser.

[0021] Among them, such as Figure 1 and Figure 3 As shown, the sealing element 1 is also provided with an exhaust channel 13 along the preset axis direction, and the exhaust channel 13 is connected to the air outlet end 101 of the atomizing component 10 and each air outlet channel 21 of the upper cover 2.

[0022] It is easy to see from the above that, since the sealing element 1 is set on the upper cover 2 of the fragrance diffuser, and the upper cover 2 covers the main body 3 of the fragrance diffuser, the sealing element 1 can elastically seal against the inner wall of the air outlet 101 of the atomizing component. Furthermore, since the sealing element 1 is provided with exhaust channels 13 along the preset axis direction, which are respectively connected to the air outlet 101 and the air outlet channels 21 of the upper cover 2, it can be seen that the sealing element 1 can not only achieve elastic sealing of the inner wall of the air outlet of the atomizing component 10, ensuring the sealing performance of the air outlet 101 of the atomizing component 10, but also ensure the blowing force of the airflow after passing through the atomizing component 10 through the exhaust channels 13 on the sealing element 1, so that the atomizing medium can be smoothly carried out by the airflow from each air outlet channel 21, thereby achieving a good misting effect.

[0023] Specifically, in some embodiments, such as Figure 1 and Figure 3 As shown, the sealing element 1 includes a support portion 11 and a plug 12. The support portion 11 is disposed on the upper cover 2, and the plug 12 is connected to the support portion 11. The plug 12 is used to partially embed into the air outlet 101 of the atomizing assembly 10, and provides elastic sealing contact with the inner wall of the air outlet 101. As shown... Figure 3 and Figure 4 As shown, the support 11 and the plug 12 are both formed around a preset axis, and together they form an exhaust channel 13 around the preset axis.

[0024] Additionally, it is worth mentioning that in some embodiments, such as Figure 1 As shown, the seal 1 can be detachably mounted on the upper cover 2, for example, as... Figure 1 and Figure 3 As shown, the seal 1 can be snapped onto the upper cover 2 using the support 11, and when the seal 1 is fixed onto the upper cover 2 by snapping, as... Figure 3As shown, the support portion 11 has a first engaging side 111 that engages with the upper cover 2, and a second engaging side 112 opposite to the first engaging side 111. The plug 12 is formed by protruding from the first engaging side 111 of the support portion 11 in a direction away from the second engaging side 112. Furthermore, through... Figure 3 It is easy to see that the first snap-fit ​​side 111 of the support portion 11 is provided with a snap-fit ​​groove 113, and the snap-fit ​​groove 113 is formed around a preset axis direction for snap-fitting and fixing with the upper cover 2. It is also worth noting that in some embodiments, the snap-fit ​​groove 113 is formed by bending the support portion 11 as a whole, specifically, as shown in... Figure 3 As shown, the support portion 11 of the seal 1 includes: a first horizontal segment 114; a first bent segment 115 formed by vertically bending and extending from the outer side of the first horizontal segment 114 from the second engaging side 112 toward the first engaging side 111; a second bent segment 116 formed by vertically bending from the inner side of the first horizontal segment 114 from the second engaging side 112 toward the first engaging side 111; and a second horizontal segment 117 formed by horizontally bending and extending from one end of the first bent segment 115 away from the first horizontal segment 114 toward the second bent segment 116. A groove 113 is formed between the first bent segment 115 and the second bent segment 116, which can engage and fix the second horizontal segment 116 to the upper cover 2.

[0025] In addition, to ensure that the airflow has sufficient pressure when passing through the exhaust channel 13, in some embodiments, such as Figure 3As shown, the plug 12 includes: an inner side 121 forming an exhaust channel 13 around a preset axis, and an outer side 122 opposite to the inner side 121, wherein the outer side 122 is in elastic sealing contact with the inner wall of the air outlet of the atomizing assembly 101. At least a portion of the plug 12 bulges out from the inner side 121 toward the outer side 122, allowing the plug 12 to engage with the air outlet 101 of the atomizing assembly 10. It is easy to see that since at least part of the plug 12 bulges out from the inner side 121 towards the outer side 122, the flow rate of the airflow when passing through the exhaust channel 13 is increased, thereby improving the blowing force of the airflow after passing through the atomizing component 10. Furthermore, since the plug 12 is flexible, when the plug 12 is partially embedded in the air outlet 101 of the atomizing component 10, the plug 12 can also undergo elastic deformation according to the sealing force on the air outlet 101, so as to ensure that the plug 12 can fully fit with the air outlet 101 of the atomizing component 10, thereby ensuring the sealing performance of the plug 12 on the air outlet 101 of the atomizing component 10. Furthermore, since the plug 12 achieves an elastic seal against the inner wall of the air outlet 101 of the atomizing component through elastic deformation after bulging, the plug 12 is not prone to deformation into the exhaust channel 13 when not subjected to radial external force. This allows the direction and magnitude of the plug 12's deformation to be controllable when the airflow passes through the exhaust channel 13, and it is not affected by the airflow magnitude, thus ensuring the misting effect of the fragrance diffuser. Simultaneously, as the airflow passes through the exhaust channel 13, the plug 12 expands further outward due to the force of the airflow, allowing the outer surface 122 of the plug 12 to fit more tightly against the inner wall of the air outlet 101 of the atomizing component, further improving the sealing performance of the plug 12 when elastically sealing the air outlet 101 of the atomizing component 10.

[0026] Furthermore, it is worth noting that in some embodiments, such as Figure 2 As shown, the plug 12 can be an approximately spherical structure, so that the inner side 121 and the outer side 122 of the plug 12 are convex arc surfaces, which can further prevent the plug 12 from deforming inward, thereby further improving the blowing force of the airflow when passing through the exhaust channel 13.

[0027] Example 2

[0028] The second embodiment of this utility model relates to a top cover assembly for a fragrance diffuser, such as... Figure 1 As shown, the cover assembly includes: a cover 2 and a seal 1 as described in Embodiment 1.

[0029] Among them, such as Figure 2 As shown, the upper cover 2 is placed on the main body 3 of the fragrance diffuser along a preset axis. The upper cover 2 is used to position the atomizing component 10 installed on the main body 3 in conjunction with the main body 3. Figure 4As shown, the upper cover 2 has at least one air vent 21. Additionally, as... Figure 1 As shown, the sealing element 1 is disposed on the upper cover 2, and the exhaust channel 13 of the sealing element 1 is connected to each exhaust channel 21.

[0030] It is easy to see from the above that, since the sealing element 1 is set on the upper cover 2 of the fragrance diffuser, and the upper cover 2 covers the main body 3 of the fragrance diffuser, the sealing element 1 can elastically seal against the inner wall of the air outlet 101 of the atomizing component. Furthermore, since the sealing element 1 is provided with exhaust channels 13 along the preset axis direction, which are respectively connected to the air outlet 101 and the air outlet channels 21 of the upper cover 2, it can be seen that the sealing element 1 can not only achieve elastic sealing of the inner wall of the air outlet of the atomizing component 10, ensuring the sealing performance of the air outlet 101 of the atomizing component 10, but also ensure the blowing force of the airflow after passing through the atomizing component 10 through the exhaust channels 13 on the sealing element 1, so that the atomizing medium can be smoothly carried out by the airflow from each air outlet channel 21, thereby achieving a good misting effect. In addition, since the top cover 2 has at least one air outlet channel 21, and each air outlet channel 21 is connected to the exhaust channel 13 of the sealing element 1, by setting each air outlet channel 21, while ensuring the amount of mist output of the atomizing medium, the atomizing medium can also be evenly diffused in the external environment after being discharged from each air outlet channel 21 with the airflow. For example, when the atomizing component 10 is a sachet, the purpose of purifying the air can be greatly improved.

[0031] Specifically, in some embodiments, such as Figure 1 As shown, the upper cover 2 includes: a cover body 23 and a sleeve body 22. Among them, combined with... Figure 2 As shown, the cover 23 is placed on the main body 3 of the fragrance diffuser along a preset axis, and simultaneously... Figure 4 As shown, each air outlet channel 21 is disposed on the cover 23, while the sleeve 22 is disposed on the cover 23 along a preset axis. The sleeve 22 is used to fit onto the atomizing component 10 and cooperates with the main body 3 to position the atomizing component 10. For example, Figure 1 and Figure 2 As shown, the sealing element 1 is disposed on the cover 23 along a preset axial direction, and at least part of it extends into the sleeve 22. The sealing element 1 is used to block the air outlet 101 of the atomizing assembly 10. Furthermore, it is not difficult to see from the above embodiment 1 that since the sealing element 1 includes a support part 11 and a plug 12, the support part 11 can be snapped onto the cover 23, and the plug 12 can extend into the sleeve 22 to block the air outlet 101 of the atomizing assembly 10.

[0032] In order to enable the support part 11 to snap onto the cover 23, such as Figure 1As shown, the cover 23 includes: a bottom 231, and a side portion 232 circumferentially surrounding the bottom 231, wherein the side portion 232 forms an accommodating space 233 on the bottom 231. Furthermore, in conjunction with... Figure 3 As shown, the upper cover assembly also includes a light-emitting component 4, which is disposed in the accommodating space 233. The light-emitting component 4 is used to engage with the sleeve 22 to secure the support portion 11 of the sealing member 1.

[0033] Specifically, such as Figure 2 As shown, the bottom 231 of the cover 23 is connected to the sleeve 22, and the sleeve 22 includes: a top 221, and a side wall 222 surrounding the top 221. The top 221 has a mounting hole 223 along a predetermined axis, and a positioning groove 2214 is also provided on the side of the top 221 facing the accommodating space 233. This positioning groove 2214 is formed around the predetermined axis and is used to engage and fix the sealing element 1, allowing a portion of the sealing element 1 to extend into the sleeve 22 through the mounting hole 223. Furthermore, to enable the positioning groove 2214 to engage the sealing element 1, in some embodiments, such as... Figure 3 As shown, the top 221 includes: a top plate 2211, an outer ring portion 2212 surrounding the outer side of the top plate 2211, an inner ring portion 2213 surrounding the inner side of the top 2211, and a snap-fit ​​portion 2215 extending horizontally from one end of the inner ring portion 2213 away from the top plate 2211 toward the mounting hole 223. Therefore, when snapping the support portion 11 of the seal 1, as... Figure 1 and Figure 3 As shown, the snap-fit ​​portion 2215 of the sleeve 22 can be snapped into the snap-fit ​​groove 113 of the support portion 11, and the second horizontal section 117 of the support portion 11 can be snapped into the positioning groove 2214. This allows the first snap-fit ​​side 111 of the support portion 11 to be snapped and positioned at the top 221 of the sleeve 22, and the plug 12 of the sealing member 1 can pass through the mounting hole 223 and extend into the sleeve 22. At the same time, the pressure of the second snap-fit ​​side 112 of the support portion 11 by the light-emitting module 4 allows the entire support portion 11 of the sealing member 1 to be snapped between the sleeve 22 and the light-emitting module 4, thereby improving the sealing performance of the plug 12 when elastically sealing the air outlet 101 of the atomizing component 10.

[0034] In addition, to further improve the mist output effect of the atomizing medium, multiple air outlet channels 21 are provided, and each air outlet channel 21 can be arranged around a preset axis. For example, such as Figure 4As shown, there are three air outlet channels 21, and these three air outlet channels 21 can be arranged equidistantly around a preset axis. By providing multiple air outlet channels 21 on the cover 23, the uniformity of the atomized medium's dispersion in the air can be further improved after it is blown out by the airflow. It should be noted that this embodiment only uses three air outlet channels 21 as an example; in other embodiments, the number of air outlet channels 21 can be increased or decreased according to actual needs.

[0035] Example 3

[0036] Embodiment 3 of this utility model relates to a fragrance diffuser, such as... Figure 2 As shown, the fragrance diffuser includes: a main body 3 and an upper cover assembly as described in Embodiment 2. The main body 3 has a mounting groove 31 along a preset axis for inserting the atomizing component 10, and the upper cover assembly is placed on the main body 3 to secure the atomizing component 10.

[0037] Specifically, in some embodiments, the atomizing component 10 can be a sachet, meaning the liquid medium stored inside the atomizing component 10 is a fragrance liquid. When the liquid medium inside the sachet is atomized to form an atomized medium, and this atomized medium is blown out through the air outlet channels 21 of the upper cover component with the airflow, it can achieve the purpose of purifying the air. Of course, in other embodiments, the atomizing component 10 can also store other liquid media, such as disinfectant, so that when the atomized medium is blown out through the air outlet channels 21 of the upper cover component with the airflow, it can achieve the purpose of disinfecting the surrounding environment.

[0038] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
