Description

Technical Field

[0001] This invention relates to the field of fragrance diffuser technology, and more particularly to an internal cavity type anti-tipping and leakage structure for fragrance diffusers. Background Technology

[0002] As people's demands for a higher standard of living increase, aroma diffusers, with their ability to purify the air and relax the mind and body, are gradually gaining acceptance. Aroma diffusers typically include an essential oil bottle to store essential oils and work in conjunction with other structural components to ensure the normal operation of the diffuser.

[0003] To prevent essential oil bottles in aroma diffusers from tipping over due to external impacts and leaking, most aroma diffusers on the market now have anti-tipping structures, such as the aroma diffuser anti-leakage structure and aroma diffuser with patent number CN218572566U. This structure atomizes the essential oil within the inner cavity, and when the bottle tipps over, a ball bearing seals the opening. However, this structure is overly complex and cumbersome, hindering quick assembly. Furthermore, a significant amount of un-atomized essential oil remains at the atomization port of the aroma diffuser, failing to collect the un-atomized oil and resulting in waste.

[0004] Therefore, it is necessary to propose an internal cavity type anti-tipping and leakage structure for aroma diffusers to simplify the anti-tipping structure of essential oil bottles, while also allowing the recovery of essential oils that have not been atomized in time, thereby improving the utilization rate of essential oils. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes an internal cavity-type anti-tipping and leakage-prevention structure for aroma diffusers to simplify the anti-tipping design of essential oil bottles. This structure also allows for the recovery of essential oils that have not been atomized in time, thereby improving the utilization rate of the essential oils.

[0006] This invention is achieved through the following technical solution:

[0007] This invention proposes an internal cavity-type anti-tipping and leakage structure for a fragrance diffuser, comprising a liquid storage bottle and an atomizing reflux assembly. The atomizing reflux assembly is fixedly connected to and conductively communicates with the liquid storage bottle. The atomizing reflux assembly includes a connector assembly, an atomizing core assembly, and a filter sound insulation cylinder. The connector assembly is fixedly and sealed to one end of the liquid storage bottle. The connector assembly has a one-way reflux section inside, one end of which is connected to the upper surface of the connector assembly, and the other end of which is conductively communicates with the liquid storage bottle. The atomizing core assembly and... The connector assembly is fixedly connected, one end of the atomizing core assembly extends into the liquid storage bottle, the filter sound insulation tube is fixed and sealed to the upper surface of the connector assembly and covers the atomizing end of the atomizing core assembly, and the other end of the atomizing core assembly extends out of one side of the filter sound insulation tube. After the liquid is atomized at the atomizing end, the excess atomized liquid in the filter sound insulation tube can be collected and returned to the liquid storage bottle through the one-way return section. When the liquid storage bottle is tilted, the one-way return section blocks the liquid.

[0008] Furthermore, the unidirectional reflux section includes a converging groove, an elastic barrier, a downstream hole, and a reflux guide groove. The converging groove is connected to the upper surface of the connector assembly. The outer periphery of the elastic barrier is fixedly connected to the connector assembly. The central region of the elastic barrier extends to the bottom of the converging groove and blocks the converging groove while closely adhering to the lower wall of the converging groove. The downstream hole is located below the elastic barrier and aligned with the converging groove. The reflux guide groove is located below the downstream hole and communicates with the downstream hole. The reflux guide groove communicates with the liquid storage bottle.

[0009] Furthermore, the elastic barrier sheet is provided with a fixing ring and an elastic plate. One end of the elastic plate is fixedly connected to the inner side of the fixing ring, and the other end of the elastic plate extends to the bottom of the converging groove and blocks the converging groove and is in close contact with the lower wall of the converging groove.

[0010] Furthermore, the reflux guide channel includes a transverse guide channel and a longitudinal guide channel. The transverse guide channel and the longitudinal guide channel are connected and form a T-shaped structure. One end of the transverse guide channel is connected to the downstream flow hole, and one end of the longitudinal guide channel is connected to the liquid storage bottle. The longitudinal guide channel and the downstream flow hole are staggered.

[0011] Furthermore, the unidirectional return section also includes a clearance space located between the converging channel and the downstream orifice, and a portion of the elastic barrier sheet is housed within the clearance space.

[0012] Furthermore, the height of the clearance space is 6 times the thickness of the elastic barrier sheet.

[0013] Furthermore, the filter sound insulation cylinder is provided with an atomizing chamber, and the atomizing end is housed within the atomizing chamber.

[0014] Furthermore, the filter sound insulation cylinder is provided with a sound insulation shielding structure. The sound insulation shielding structure is located above the atomizing chamber and is in communication with the atomizing chamber. The sound insulation shielding structure includes a conical top and a filter ring. The outer periphery of the filter ring is fixedly connected to the inner wall of the filter sound insulation cylinder. The conical top is fixedly connected to the center of the filter ring. The atomizing end faces the conical top.

[0015] Furthermore, the filter ring is provided with a plurality of first blocking blocks and a plurality of second blocking blocks. The plurality of first blocking blocks are evenly distributed circumferentially, and the plurality of second blocking blocks are evenly distributed circumferentially below the plurality of first blocking blocks and staggered.

[0016] Furthermore, the atomizing recirculation assembly also includes a top cover, which covers the top of the filter sound insulation cylinder. The top cover is provided with a flow channel, which is connected to the interior of the filter sound insulation cylinder.

[0017] The beneficial effects of this invention are:

[0018] This invention employs an atomizing and reflux assembly to atomize the essential oil in the storage bottle within its inner cavity. After the atomizing core assembly atomizes the essential oil, the atomized oil is propelled outwards from the filter and soundproof cylinder by air pressure. Incompletely atomized essential oil flows back along the inner wall of the filter and soundproof cylinder to the surface of the connector assembly, and then flows back into the storage bottle via the one-way reflux section. The one-way reflux section only guides the essential oil into the storage bottle. This simple structure effectively recovers the essential oil, improving its utilization rate. Furthermore, if the storage bottle is tilted, the essential oil inside cannot flow out from the one-way reflux section to the surface of the connector assembly, effectively preventing spilled essential oil. In summary, this cavity-type anti-tipping and leakage structure for aroma diffusers uses a simple structure to prevent essential oil spillage and leakage, while also allowing for the recovery of un-atomized essential oil, effectively improving its utilization rate.

Detailed Implementation

[0027] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0028] Please refer to Figures 1-5 This invention proposes an internal cavity-type anti-tipping and leakage structure for a fragrance diffuser, including a liquid storage bottle 1 and an atomizing reflux assembly 2. The atomizing reflux assembly 2 is fixedly connected to and conductively communicates with the liquid storage bottle 1. The atomizing reflux assembly 2 includes a connector assembly 21, an atomizing core assembly 22, and a filter sound insulation cylinder 23. The connector assembly 21 is fixedly and sealed to one end of the liquid storage bottle 1. The connector assembly 21 has a one-way reflux section 211 inside. One end of the one-way reflux section 211 is connected to the upper surface of the connector assembly 21, and the other end of the one-way reflux section 211 is conductively communicated with the liquid storage bottle 1. The atomizing core assembly... The atomizing core assembly 22 is fixedly connected to the connector assembly 21. One end of the atomizing core assembly 22 extends into the liquid storage bottle 1. The filter sound insulation cylinder 23 is fixed and sealed to the upper surface of the connector assembly 21 and covers the atomizing end 221 of the atomizing core assembly 22. The other end of the atomizing core assembly 22 extends out of one side of the filter sound insulation cylinder 23. After the liquid is atomized at the atomizing end 221, the excess atomized liquid in the filter sound insulation cylinder 23 can be collected and returned to the liquid storage bottle 1 through the one-way return section 211. When the liquid storage bottle 1 is tilted, the one-way return section 211 blocks the liquid.

[0029] In this embodiment, when atomizing the essential oil, the atomizing reflux assembly 2 atomizes the essential oil in the storage bottle 1 within its inner cavity. Specifically, the air pump inside the fragrance diffuser blows high-pressure gas into one end of the atomizing core assembly 22 located outside the filter sound insulation cylinder 23, causing the atomizing end 221 to generate negative pressure and draw out and atomize the essential oil in the storage bottle 1. After the atomizing core assembly 22 atomizes the essential oil, the atomized essential oil is pushed out of the filter sound insulation cylinder 23 by the air pressure, while the essential oil that is not completely atomized will adhere to the filter sound insulation cylinder. After accumulating to a certain extent, the essential oil will flow back along the inner wall of the filter and sound insulation cylinder 23 to the surface of the connector assembly 21, and then flow back into the storage bottle 1 through the one-way return section 211. The one-way return section 211 can only guide the essential oil into the storage bottle 1. The structure is simple and effectively recycles the essential oil, improving the utilization rate of the essential oil. Moreover, after the storage bottle 1 is tilted, the essential oil in the storage bottle 1 cannot flow out from the one-way return section 211 to the surface of the connector assembly 21, effectively blocking the tilted essential oil.

[0030] In summary, the internal cavity anti-tipping and leakage prevention structure for aroma diffusers can prevent essential oils from spilling and leaking using a simple structure, while also allowing for the recovery of essential oils that are not atomized in time, effectively improving the utilization rate of essential oils.

[0031] In this embodiment, the unidirectional return section 211 includes a converging groove 2111, an elastic barrier 2112, a downstream hole 2113, and a return guide groove 2114. The converging groove 2111 is connected to the upper surface of the connector assembly 21. The elastic barrier 2112 is a circular diaphragm with a thin thickness and elasticity. The outer periphery of the elastic barrier 2112 is fixedly connected to the connector assembly 21. The central region of the elastic barrier 2112 extends below the converging groove 2111 and blocks the converging groove 2111, closely adhering to the lower wall of the converging groove 2111. The downstream hole 2113 is located below the elastic barrier 2112 and aligned with the converging groove 2111. The flow guide channel 2114 is located below the flow hole 2113 and communicates with the flow hole 2113. The return guide channel 2114 is communicated with the storage bottle 1. When the essential oil is recycled, the essential oil flows back along the inner wall of the filter sound insulation cylinder 23 to the surface of the connector assembly 21, and then flows into the collection channel 2111. After the essential oil accumulates to a certain amount in the collection channel 2111, it will bend the elastic barrier 2112. The bottom of the collection channel 2111 has an opening. At this time, the essential oil flows along the opening into the flow hole 2113 and continues to flow downward into the return guide channel 2114, and then flows into the storage bottle 1 from the return guide channel 2114. This is the essential oil recycling process.

[0032] In this embodiment, the elastic barrier sheet 2112 is provided with a fixing ring 21121 and an elastic plate 21122. One end of the elastic plate 21122 is fixedly connected to the inner side of the fixing ring 21121, and the other end of the elastic plate 21122 extends to the bottom of the collecting groove 2111 and blocks the collecting groove 2111 and is in close contact with the lower wall of the collecting groove 2111. The fixing ring 21121 is used to fix it externally so as to support the elastic plate 21122 horizontally. When the essential oil has not yet gathered in the collecting groove 2111, the elastic plate 21122 blocks the collecting groove. 2111 and closely attached to the lower wall of the gathering tank 2111, when the essential oil accumulates to a certain amount (the amount of one drop) in the gathering tank 2111, the weight of the essential oil will bend the elastic plate 21122, and then a drop of essential oil will enter the outflow hole 2113. Since the essential oil in the gathering tank 2111 needs to be gathered again, and the weight of the essential oil is not enough to bend the elastic plate 21122 during the gathering process, the elastic plate 21122 will block the gathering tank 2111 again and closely attached to the lower wall of the gathering tank 2111 until the next drop of essential oil is formed.

[0033] In this embodiment, the reflux guide channel 2114 includes a transverse guide channel 21141 and a longitudinal guide channel 21142. The transverse guide channel 21141 and the longitudinal guide channel 21142 are connected and form a T-shape. One end of the transverse guide channel 21141 is connected to the downstream hole 2113, and one end of the longitudinal guide channel 21142 is connected to the storage bottle 1. The longitudinal guide channel 21142 and the downstream hole 2113 are staggered. After the essential oil flows into the transverse guide channel 21141 from the downstream hole 2113, the essential oil will flow along the transverse guide channel 21141 towards the longitudinal guide channel 21142, and finally flow into the storage bottle 1 from the longitudinal guide channel 21142. The transverse guide channel 21141 and the longitudinal guide channel 21142 are connected. The T-shaped structure of the guide channel 21142 provides sufficient time for the elastic plate 21122 to recover. When the liquid storage bottle 1 is tilted, the essential oil will flow into the longitudinal guide channel 21142. Since the longitudinal guide channel 21142 is staggered from the flow hole 2113, the essential oil still needs to pass through the transverse guide channel 21141 to reach the elastic plate 21122. This prolongs the outflow time of the essential oil. Even if the essential oil bends the elastic plate 21122 into the flow hole 2113 before tilting, the elastic plate 21122 will have enough time to rebound when tilting to seal the bottom wall of the collecting channel 2111, preventing the essential oil from flowing out.

[0034] In this embodiment, the one-way return section 211 also includes a clearance space 2115, which is located between the converging groove 2111 and the downstream hole 2113. A portion of the elastic barrier sheet 2112 is housed within the clearance space 2115. The clearance space 2115 provides sufficient space for the elastic plate 21122 in the elastic barrier sheet 2112 to undergo elastic deformation. The height of the clearance space 2115 is 6 times the thickness of the elastic barrier sheet 2112. This height is set to prevent the elastic plate 21122 from being bent excessively by too much essential oil and becoming unable to return to its original position.

[0035] In this embodiment, the filter sound insulation cylinder 23 is provided with an atomizing chamber 231, and the atomizing end 221 is housed in the atomizing chamber 231. When the atomizing end 221 performs atomization, the atomization is performed in the atomizing chamber 231. Since the gas continues to enter the atomizing chamber 231, the air pressure in the atomizing chamber 231 increases, which blows out finer atomized essential oils, while larger essential oil particles are blown to the inner wall of the atomizing chamber 231 and finally flow back. This can improve the atomization effect of the essential oils and filter out large essential oil particles.

[0036] In this embodiment, a sound-insulating shielding structure 232 is provided inside the filter sound-insulating cylinder 23. The sound-insulating shielding structure 232 is located above the atomizing chamber 231 and is in communication with the atomizing chamber 231. The sound-insulating shielding structure 232 includes a conical top 2321 and a filter ring 2322. The filter ring 2322 is a ventilation structure. The outer periphery of the filter ring 2322 is fixedly connected to the inner wall of the filter sound-insulating cylinder 23. The conical top 2321 is fixedly connected to the center of the filter ring 2322. The atomizing end 221 faces... Conical top 2321; When atomizing at the atomizing end 221, a "hissing" sound is produced. Under the action of air pressure, the spray is sprayed towards the inner wall of the conical top 2321 and flows along the inner wall of the conical top 2321 to the filter ring 2322, and then flies out from the filter ring 2322. The conical top 2321 and the filter ring 2322 have blocked most of the sound, making the sound heard by the end user extremely low, effectively achieving sound insulation.

[0037] In this embodiment, the filter ring 2322 is provided with a plurality of first blocking blocks 23221 and a plurality of second blocking blocks 23222. The plurality of first blocking blocks 23221 are evenly distributed circumferentially, and the plurality of second blocking blocks 23222 are evenly distributed circumferentially below the plurality of first blocking blocks 23221 and staggered. Since the essential oil will produce atomized particles of different sizes after atomization, and all atomized particles are still propelled by air pressure, the smaller atomized particles can follow the airflow more accurately, while the larger atomized particles have difficulty following the airflow accurately. The staggered distribution of the plurality of first blocking blocks 23221 and the plurality of second blocking blocks 23222 is to block the larger atomized particles by the staggered parts, so that the larger atomized particles are collected, while the smaller atomized particles are smoothly dispersed to the outside, avoiding the phenomenon of essential oil splashing around the fragrance diffuser.

[0038] In this embodiment, the atomizing reflux assembly 2 also includes an upper cover 24, which covers the top of the filter and sound insulation cylinder 23. The upper cover 24 is provided with a flow channel 241, which is connected to the interior of the filter and sound insulation cylinder 23. The upper cover 24 is designed to strengthen the blocking of the atomized essential oil, so that the essential oil particles that finally flow out are smaller, thus achieving a subtle and silent effect.

[0039] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.
