Description

Technical Field

[0001] This utility model relates to the field of essential oil storage technology, specifically to a sealed storage tank for camphor tree essential oil. Background Technology

[0002] Camphor tree oil, a volatile oily liquid with a strong aromatic scent extracted from the leaves, branches, or roots of the camphor tree, has wide applications in medicine, food, and daily chemical industries. However, its storage has always been a challenging issue.

[0003] Existing camphor tree essential oil storage containers have revealed numerous shortcomings in practical use. From a temperature control perspective, the optimal storage temperature for camphor tree essential oil is typically around 25°C, but existing containers struggle to precisely control the internal temperature. Excessively high ambient temperatures accelerate the volatilization of some components, leading to a decline in oil quality; conversely, excessively low temperatures may cause the waxy components to solidify. Furthermore, existing storage containers present significant drawbacks in the processes of adding and removing essential oil. Due to the lack of effective insulation, the essential oil inevitably comes into contact with air. On one hand, oxygen in the air reacts with the essential oil, altering its composition, resulting in changes in aroma and reduced efficacy. On the other hand, the high volatility of essential oils accelerates this evaporation process upon contact with air, leading to waste and increased usage costs.

[0004] In conclusion, developing a new type of storage container that can effectively maintain the storage temperature of camphor tree essential oil while reducing the contact between the essential oil and air during the addition and release of the essential oil, thus preventing contamination and volatilization, is of great practical significance for improving the storage quality of camphor tree essential oil, extending its shelf life, and reducing usage costs.

[0040] Example:

[0041] like Figures 1 to 9 As shown, this embodiment discloses a sealed storage tank for camphor tree essential oil, including an inner tank 10, an outer tank 11, and an isolation component 12. The inner tank 10 is disposed inside the outer tank 11.

The liquid filling component 13 penetrates through the top of the outer tank 11 and extends to the outside of the outer tank 11, and the liquid draining component 14 penetrates through the bottom of the outer tank 11 and extends to the outside of the outer tank 11.

[0042] The isolation assembly 12 includes an air inlet pipe 15, an air outlet pipe 16, and a pair of diaphragm members 17. The top of the inner tank 10 is provided with an air inlet 18 and an air outlet 19.

One end of the air outlet pipe 16 is detachably connected to the air outlet 19, and an air outlet valve 21 is provided on the air outlet pipe 16. The pair of diaphragm members 17 are respectively disposed in the liquid filling assembly 13 and the liquid discharging assembly 14, and are detachably connected to the liquid filling assembly 13 and the liquid discharging assembly 14 respectively.

[0043] The diaphragm component 17 includes a fixing ring 22 and four fan-shaped diaphragms 23. The four fan-shaped diaphragms 23 are disposed inside the fixing ring 22 and are arranged in a circumferential array with respect to the center of the fixing ring 22. One side of each of the four fan-shaped diaphragms 23 is fixedly connected to the inner sidewall of the fixing ring 22, and adjacent fan-shaped diaphragms 23 are in contact with each other.

[0044] This invention utilizes a pair of diaphragm members 17, which are respectively disposed within the liquid filling assembly 13 and the liquid discharging assembly 14. When essential oil is added, it is continuously injected into the liquid filling assembly 13, impacting the diaphragm members 17 and causing the four fan-shaped diaphragms 23 within each diaphragm member 17 to open, allowing the essential oil to enter the inner tank 10, thus completing the essential oil addition process. When discharging essential oil, inert gas is injected into the inner tank 10 through the air inlet pipe 15, increasing the pressure within the inner tank 10 and forcing the essential oil into the liquid discharging assembly 14. The essential oil impacts the diaphragm members 17 within the liquid discharging assembly 14, causing the four fan-shaped diaphragms 23 within each diaphragm member 17 to open, allowing the essential oil to be released. In both processes, the diaphragm members 17 require the action of the essential oil to open, thus effectively reducing the contact between the essential oil and air within the inner tank 10. This invention solves the problem of essential oil contamination and evaporation caused by the lack of effective isolation measures during the addition and dispensing of essential oil in current camphor tree essential oil storage containers.

[0045] As a further preferred embodiment, one end of the air intake pipe 15 is detachably connected to the air intake port 18 via a thread, and one end of the air outlet pipe 16 is detachably connected to the air outlet port 19 via a thread.

Meanwhile, the inlet port 26 and inlet tube head 24 facilitate the installation of the inlet assembly 13 and the addition of essential oils. When adding essential oils, the oils pass through the inlet pipe 25, then through the inlet valve 27, and then into the inlet tube head 24, thus being added into the inner tank 10.

[0057] Each of the two can lids 36 is provided with a limiting groove 37, and the top and bottom of the main tank body 35 are respectively provided with limiting rings 38 that cooperate with the limiting grooves 37. When the can lid 36 is connected to the main tank body 35, the limiting rings 38 are inserted into the limiting grooves 37.

[0058] By setting the outer tank 11 as a split structure of the main tank 35 and a pair of tank lids 36, the assembly of the outer tank 11 and the inner tank 10 can be facilitated.

The sealing gasket 41 is fixedly connected to the lids 36, and the top and bottom of the inner tank 10 can respectively contact the sealing gasket 41 in the pair of lids 36.

[0063] By providing receiving grooves 40 on a pair of can lids 36 and providing sealing gaskets 41 in the receiving grooves 40, the top and bottom of the inner can body 10 are made to contact the sealing gaskets 41 in the pair of can lids 36 during installation, thereby effectively improving the sealing performance at the connection between the inner can body 10 and the pair of can lids 36, thus achieving a better storage effect for essential oils.

[0064] To facilitate maintaining the storage temperature of essential oils, this embodiment is an improvement on the above embodiment.

[0070] Working principle of this utility model:

[0071] When adding essential oil, the essential oil is continuously injected into the filling component 13, which impacts the diaphragm 17 inside the filling component 13, causing the four fan-shaped diaphragms 23 in the diaphragm 17 to open, thus allowing the essential oil to enter the inner tank 10, completing the essential oil addition process. When discharging essential oil, inert gas is injected into the inner tank 10 through the air inlet pipe 15, thereby increasing the pressure inside the inner tank 10 and forcing the essential oil into the discharging component 14. The essential oil impacts the diaphragm 17 in the discharging component 14, causing the four fan-shaped diaphragms 23 in the diaphragm 17 to open, thus allowing the essential oil to be discharged.
