Description

[Technical Field]

[0001] The present invention relates to the technical field of aroma diffusers, and more particularly to a leak-proof, circulation atomization structure for essential oil aroma diffusers. [Background technology]

[0002] In order to improve the living environment, people often fill a bottle with perfume and insert flowers or other cotton heads to diffuse the scent in the bottle into the environment to achieve the effect of fragrance. However, in this method, the perfume evaporates freely due to its own characteristics, and the perfume is not sufficiently atomized. In order to improve this situation, the prior art has developed an aroma diffuser.

[0003] In order to prevent the essential oil bottle in the aroma machine from colliding with an external force and tipping over, causing the essential oil to leak out of the bottle, most essential oil bottles in aroma machines currently on the market are equipped with a tip-over prevention structure. For example, the aroma machine oil leakage prevention structure and aroma machine of patent number CN218572566U atomizes the essential oil in the inner cavity, and when the essential oil bottle tips over, the opening is blocked by a rolling ball. However, this structure is complex and cumbersome, making it difficult to assemble quickly. For aroma machines, a large amount of essential oil remains in the essential oil atomization port, making it impossible to recover the unatomized essential oil, resulting in waste of essential oil.

[0004] To solve the problem of essential oil recovery, some manufacturers have adopted guide grooves as a guide structure to guide the reflux of excess essential oil into the essential oil bottle, allowing the excess essential oil to be refluxed. However, if external substances are introduced, the essential oil in the essential oil bottle will be contaminated and deteriorated after long-term use. Therefore, if the refluxed essential oil can be distinguished and atomized, the efficiency of essential oil use can be improved.

[0005] Therefore, it is necessary to propose a leak-proof circulating atomization structure for essential oil aroma diffusers that collects the recycled essential oil separately and preferentially consumes the recycled essential oil in a circulating atomization manner. Summary of the Invention [Problem to be solved by the invention]

[0006] To solve the above problems, the present invention proposes a leak-proof circulating atomization structure for essential oil aroma diffusers, which collects the recycled essential oil separately and preferentially consumes the recycled essential oil in a circulating atomization manner. [Means for solving the problem]

[0007] The present invention is realized by the following technical solutions:

[0008] The present invention proposes a liquid leakage-proof circulation atomization structure for an essential oil aroma diffuser, which includes a top cover, an atomization jet head, and a mist discharge and reflux cover assembly, wherein the atomization jet head is fixedly connected to the top of the top cover, the mist discharge and reflux cover assembly is fixedly connected to the top cover to cover the atomization jet head, a branch adsorption pipe is installed on one side of the atomization jet head, one end of which is connected to the atomization jet head, a liquid refill groove is installed on the top of the top cover, which is connected to the mist discharge and reflux cover assembly, and the other end of the branch adsorption pipe is inclined and extends downward toward the liquid refill groove and is connected to the liquid refill groove.

[0009] Furthermore, the mist discharge and reflux cover assembly includes a fragrance expansion and reflux shell and a mist discharge lid, the mist discharge lid is tightly and fixedly connected to the top of the fragrance expansion and reflux shell and is connected to the fragrance expansion and reflux shell, the mist discharge lid is connected to the outside, the bottom of the fragrance expansion and reflux shell is fixedly connected to the top lid and covers the atomization jet head, and the fragrance expansion and reflux shell is connected to the liquid refill groove.

[0010] Furthermore, a reflux cover is installed in the fragrance expansion reflux shell, located above the atomization jet head and within the range of the liquid refill groove.

[0011] Furthermore, a first mist discharge channel is installed in the fragrance expansion and circulation shell, which is connected to the mist discharge cover and the liquid refill groove.

[0012] Furthermore, a flow guide slope connected to the first mist discharge channel is installed within the fragrance expansion circulation shell.

[0013] Furthermore, the mist discharge cover is provided with a reflux chamber communicating with the first mist discharge channel.

[0014] Furthermore, the mist discharge cover is provided with a second mist discharge channel that is in communication with the first mist discharge channel.

[0015] Furthermore, a blocking portion for returning essential oil is provided around the inner wall of the second mist discharge channel.

[0016] Furthermore, the blocking portion has an annular reverse tapered structure.

[0017] Furthermore, the top cover is provided with a vent pipe for balancing the air pressure, which leads to the bottle body below and extends upward to a position higher than the liquid refill groove. [Effects of the Invention]

[0018] The beneficial effects of the present invention are as follows: The present invention uses a mist discharge and reflux cover assembly to diffuse the essential oil mist ejected from the spray head and recover excess essential oil mist. The liquid refill groove installed on the top cover accumulates and recirculates the recovered excess essential oil mist to form essential oil. The tributary adsorption tube adsorbs and atomizes the essential oil in the liquid refill groove to form re-atomization. During the spraying process, the tributary adsorption tube is located on one side of the atomization nozzle and is close in distance, so the essential oil in the liquid refill groove is preferentially atomized. In this way, the recycled essential oil can be consumed preferentially using the recycled atomization method. In summary, this leakage-proof circulation atomization structure for essential oil aroma diffusers preferentially consumes recycled essential oil, which is advantageous for improving the efficiency of essential oil use.

DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to describe the technical solutions of the present invention more clearly and completely, the present invention will be further described below in conjunction with the accompanying drawings.

[0021] 1 and 2, the present invention proposes a leak-proof circulation atomization structure for an essential oil aroma diffuser, which includes a top cover 1, an atomization jet head 2, a mist discharge and reflux cover assembly 3, and a bottle body 4. The top cover 1 is capped on the opening of the bottle body 4, the atomization jet head 2 is fixedly connected to the top of the top cover 1, a main suction pipe 22 is installed below the atomization jet head 2 and extends downward into the bottle body 4, and the mist discharge and reflux cover assembly 3 is installed on the top It is fixedly connected to the lid 1 to cover the atomization jet head 2, and a branch adsorption pipe 21 is installed on one side of the atomization jet head 2, one end of which is connected to the atomization jet head 2, and a liquid replenishment groove 11 is installed on the top of the upper lid 1 and connected to the mist discharge reflux cover assembly 3, and the other end of the branch adsorption pipe 21 extends inclined downward toward the liquid replenishment groove 11 and is connected to the liquid replenishment groove 11, and an air intake pipe 23 is installed on the other side of the atomization jet head 2, which is connected to the air pump.

[0022] In this embodiment, the mist discharge reflux cover assembly 3 can diffuse the essential oil mist ejected from the atomization jet head 2 and also recover excess essential oil mist. The liquid refill groove 11 installed on the top cover 1 is the essential oil formed by accumulating and refluxing the recovered excess essential oil mist. The branch adsorption pipe 21 adsorbs and atomizes the essential oil in the liquid refill groove 11 to form re-atomization. During the spraying process, the main suction pipe 22 extends downward into the bottle body 4, and the stroke when the essential oil is adsorbed is relatively long. The branch adsorption pipe 21 is located on one side of the atomization nozzle 2, is close to it, and has a short stroke, so the essential oil in the liquid refill groove 11 is absorbed and atomized. The oil is preferentially atomized, and if the amount of essential oil stored in the liquid refill groove 11 is sufficiently large, the amount of returned essential oil used in the liquid refill groove 11 during essential oil spraying will be greater than the amount of essential oil used in the bottle body 4 during atomization; that is, the amount of essential oil used in the liquid refill groove 11 is relatively large. When there is not enough returned essential oil in the liquid refill groove 11, the essential oil in the bottle body 4 will be used as is. After using it a sufficient number of times, there will be enough returned essential oil stored in the liquid refill groove 11. When atomization is continued, the essential oil will be atomized according to the above process, and in this way, the returned essential oil can be consumed preferentially through the method of circulating atomization.

[0023] To summarize, the leakage-proof circulating atomization structure for essential oil aroma diffusers of the present invention can collect the recycled essential oil separately and preferentially consume the recycled essential oil in a circulating atomization manner, which is advantageous for improving the utilization efficiency of essential oils.

[0024] In this embodiment, the mist discharge and reflux cover assembly 3 includes a fragrance expansion and reflux shell 31 and a mist discharge lid 32. The mist discharge lid 32 is tightly and fixedly connected to the top of the fragrance expansion and reflux shell 31 and is connected to the fragrance expansion and reflux shell 31. The mist discharge lid 32 is connected to the outside. The bottom of the fragrance expansion and reflux shell 31 is fixedly connected to the top cover 1 and covers the atomization jet head 2. The fragrance expansion and reflux shell 31 is connected to the liquid refill groove 11. When the atomization jet head 2 atomizes essential oil, the atomized essential oil first diffuses into the fragrance expansion and reflux shell 31, and the particles are relatively small. Some of the larger mist is captured on the inner wall of the fragrance expansion and reflux shell 31, and as the mist accumulates on the inner wall of the fragrance expansion and reflux shell 31, essential oils are formed and flow downward, returning to the liquid refill groove 11. Because the air pressure jet remains, the mist continues to scatter and fly into the mist discharge cover 32. Some of the mist with relatively large particles is also captured on the inner wall of the mist discharge cover 32, and as the mist accumulates on the inner wall of the mist discharge cover 32, essential oils are formed and flow downward, returning to the liquid refill groove 11 via the inner wall of the fragrance expansion and reflux shell 31, and the remaining mist with relatively small particles is scattered to the outside.

[0025] In this embodiment, a reflux cover 311 is installed inside the aroma-expanding reflux shell 31, located above the atomization-spouting head 2 and within the range of the liquid refilling groove 11. When the atomization-spouting head 2 atomizes essential oil, the atomized essential oil is first sprayed into the reflux cover 311, which captures the relatively large particles of mist. The captured mist adheres to the inner wall of the reflux cover 311. When there is a sufficient amount of mist on the inner wall, droplets are formed and flow downward, eventually dripping into the liquid refilling groove 11. The remaining mist continues to diffuse outside the reflux cover 311.

[0026] In this embodiment, a first mist discharge channel 312 is installed inside the fragrance expansion reflux shell 31, which is connected to the mist discharge cover 32 and the liquid refill groove 11. The first mist discharge channel 312 is used to direct mist into the mist discharge cover 32. The first mist discharge channel 312 may be installed on one side of the reflux cover 311, or may be installed around the reflux cover 311. Installing it around the reflux cover 311 makes the mist discharge more uniform. The inner wall of the first mist discharge channel 312 can also capture relatively large particles of mist. When there is enough mist on the inner wall, droplets are formed and flow downward, eventually flowing into the liquid refill groove 11.

[0027] In this embodiment, a guide slope 313 connected to the first mist discharge channel 312 is installed inside the fragrance expansion reflux shell 31. During atomization, if there is a blockage on the inner wall, the mist will adhere to the inner wall, and if there is a sufficient amount of mist attached, droplets will be formed. The guide slope 313 is installed at the top position of the reflux cover 311 and is used to guide the droplets formed in the space between the reflux cover 311 and the mist discharge cover 32 toward the inner wall of the first mist discharge channel 312, and further flow along the inner wall of the first mist discharge channel 312 into the liquid refill groove 11.

[0028] In this embodiment, the mist discharge cover 32 is equipped with a reflux chamber 321 that is connected to the first mist discharge channel 312. The reflux chamber 321 is used to capture large particle mist that flows out from the first mist discharge channel 312. When there is a sufficient amount of mist attached to the inner wall of the reflux chamber 321, droplets are formed and flow downward. The droplets flow into the liquid refill groove 11 along the inner wall of the first mist discharge channel 312. When the essential oil bottle is accidentally tipped over, the reflux chamber 321 can prevent the essential oil in the liquid refill groove 11 from leaking out.

[0029] In this embodiment, the mist discharge cover 32 is provided with a second mist discharge channel 322 which is connected to the first mist discharge channel 312. The second mist discharge channel 322 is used to diffuse small particle mist to the outside. The second mist discharge channel 322 is located in the center of the reflux chamber 321 and above the reflux cover 311. When atomizing, the mist passes through the reflux cover 311, the first mist discharge channel 312, and the reflux chamber 321 in sequence, and finally flows out of the second mist discharge channel 322 to be diffused to the outside.

[0030] In this embodiment, a blocking section 3221 for refluxing essential oil is installed around the inner wall of the second mist discharge channel 322. When atomization is performed, the mist eventually flows out from the second mist discharge channel 322 to the outside. During the outflow process, a small amount of large mist particles still adhere to the inner wall of the second mist discharge channel 322. If the amount of adhered mist is sufficient, droplets will be formed. The installation of the blocking section 3221 increases the obstruction of large mist particles and further recovers the essential oil. At the same time, if the essential oil bottle is accidentally tipped over, the blocking section 3221 can block the essential oil flowing out from the second mist discharge channel 322. The blocking section 3221 has a circular reverse tapered structure. The circular reverse tapered structure is used to guide the essential oil formed as droplets downward and drop them into the reflux chamber 321, making it easy to produce and at the same time saving the space occupied externally.

[0031] In this embodiment, a vent pipe 12 is installed on the top cover 1 to balance the air pressure, and the vent pipe 12 leads to the bottle body 4 below. The vent pipe 12 extends upward and is higher than the liquid refill groove 11. When atomizing, negative pressure is created at the position of the atomizing head 2 in the form of an air pump jet. At this time, the main suction pipe 22 sucks up the essential oil in the bottle body 4 and atomizes it. In order to ensure smooth absorption by the main suction pipe 22, the vent pipe 12 is installed to balance the air pressure within the bottle body 4. When the bottle body 4 is accidentally tipped over, the essential oil flows out of the vent pipe 12 and is captured by the reflux cover 311. When the bottle body 4 is restored, the essential oil captured by the reflux cover 311 flows into the liquid refill groove 11.

[0032] Of course, the present invention may have many other embodiments, and all other embodiments that can be obtained by a person skilled in the art based on this embodiment without paying any creative labor belong to the scope protected by the present invention. [Explanation of symbols]
