Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smelling devices, and mainly relates to a portable nose incense pot. BACKGROUND

[0002] Essential oil is the concentrated plant essence extracted from trees, roots, leaves, seeds, herbs, fruits or flowers. Each plant's essential oil contains its unique fragrance. In addition to being used on the body, it can also be inhaled through the human sense of smell to allow the user to feel fresh air.

[0003] China has a history of using incense for thousands of years, and carrying incense is also a common scene for ancient people. However, the incense pouch of ancient people cannot be accepted by modern people. Modern industrial extraction technology makes essential oil easier to obtain, but it is inconvenient to carry essential oil. The existing bottle for carrying essential oil on the market is only an ordinary container, which cannot simultaneously solve the carrying and fragrance spreading needs, and essential oil has the characteristics of being afraid of light, small molecules being easy to penetrate, being easy to volatilize, and being wasted if stored carelessly, thereby causing loss to the user.

[0004] Although there are ultrasonic fragrance spreading, wood fragrance spreading, volcanic stone, rattan, candle, spray fragrance spreading and other fragrance spreading modes, they are not convenient to carry. There is also a traditional incense paste for fragrance spreading, which needs to be applied to the skin and becomes a use obstacle. The traditional incense burner has also developed into a small size, but it is also not convenient for personal portable fragrance spreading.

[0005] The present application obtains inspiration from the relatively popular snuff bottle in the Qing Dynasty, and makes a product which is convenient to carry, can continuously release essential oil for a long time, and can maintain stable fragrance spreading on the basis of the shape and structure of the snuff bottle. However, there are challenges such as safe storage and carrying of essential oil, how to make essential oil continuously spread under passive conditions, and adaptability to the environment during fragrance spreading. SUMMARY

[0009] As an improvement of the above-mentioned scheme, the fragrance expander is mainly a fragrance wood or a fragrance stone.

[0010] As an improvement of the above-mentioned scheme, the chamber height size of the first chamber is between 30-50mm, and the chamber height size of the second chamber is between 10-30mm.

[0011] As an improvement of the above-mentioned scheme, the inner diameter of the capillary and the liquid surface height in the capillary can be judged by using the following formula: h=2γcosθ / (ρgr), wherein h=liquid surface height, γ=liquid surface tension, θ=contact angle, ρ=liquid density, g=gravity acceleration, and r=capillary inner radius.

[0012] As an improvement of the above-mentioned scheme, the liquid surface tension γ, the contact angle θ, the liquid density ρ, and the gravity acceleration g are all fixed values, and the capillary inner radius r and the liquid surface height h are inversely proportional.

[0013] The present application has the beneficial effect that the top end of the capillary does not go below the chamber bottom of the first chamber after passing through the interval between the first chamber and the second chamber, the liquid surface height of the essential oil in the second chamber is higher than the bottom end of the capillary, the continuous slow release of the essential oil is realized by using the capillary effect, the storage and slow release of the essential oil are perfectly solved, and the first chamber or the second chamber can be heated by the human body or the hand when it is carried, the speed of the essential oil outflow or recovery is controlled by the air pressure imbalance caused by thermal expansion and contraction.

[0019] As shown in Figure 1 and Figure 2 A portable nose fragrance pot, comprising a pot body 1 and a cover 2, the top end of the pot body 1 is provided with the cover 2, the pot body 1 is provided with a first chamber 101 and a second chamber 102 from top to bottom, a plurality of fragrance expansion bodies 103 are arranged in the first chamber 101, and essential oil 104 is arranged in the second chamber 102, the bottom end of the first chamber 101 is provided with a capillary tube 105, and the bottom end of the second chamber 102 is provided with a silica gel sealing cover 3.

[0020] Further, in the above scheme, the top end of the capillary tube 105 passes through the interval between the first chamber 101 and the second chamber 102 and is not lower than the cavity bottom of the first chamber 101, and the liquid level of the essential oil 104 in the second chamber 102 is higher than the bottom end of the capillary tube 105.

[0021] Further, in the above scheme, the fragrance expansion body 103 is mainly fragrance expansion wood or fragrance expansion stone.

[0022] Further, in the above scheme, the chamber height size of the first chamber 101 is between 30-50mm, the chamber height size of the second chamber 102 is between 10-30mm, the height of the first chamber 101 needs to consider the influence of portability, the height of the second chamber 102 needs to consider the relationship between capacity and height, the size of the kettle 1 should meet the size of carrying, in general, the essential oil carried in the nose incense kettle is 10-15ml, which is enough to meet the use demand, too much capacity of the essential oil carried will lead to too large volume of the second chamber 102, affecting the overall portability, in the case of determining the capacity of the essential oil 104 in the second chamber 102, the higher the height of the second chamber 102, the thinner the inner diameter of the capillary tube 105, when the height of the second chamber 102 is too high, the inner diameter of the capillary tube 105 is very thin, the rising height of the essential oil 104 is also limited, which will directly affect the use effect, for example, when the height of the second chamber 102 is 10mm, the capacity of the essential oil is 10ml, the height of the capillary tube is not too high, and the inner diameter is not too thin, which can meet the use demand, when the height of the second chamber 102 is 30mm, the capacity of the essential oil is 15ml, the height of the capillary tube is too high, and the inner diameter is very thin, which cannot meet the normal use demand, but still can be used.

[0023] Further, in the above scheme, the inner diameter of the capillary tube 105 and the liquid level height in the capillary tube 105 can be judged using the following formula: h=2γcosθ / (ρgr), wherein h=liquid level height, γ=liquid surface tension, θ=contact angle, ρ=liquid density, g=acceleration of gravity, and r=capillary tube inner radius.

[0024] Further, in the above scheme, the liquid surface tension γ, the contact angle θ, the liquid density ρ and the acceleration of gravity g are all constant values, the values of the capillary tube inner radius r and the liquid level height h are inversely proportional.

[0025] In the specific structure of the present application, when the capillary tube 105 makes the liquid level of the essential oil 104 higher than the height of the capillary tube 105 by capillary effect, the essential oil 104 can rise from the second chamber 102 to the bottom end face of the first chamber 101, the fragrance diffusing body 103 can contact the essential oil 104, the pot 1 can be shaken to make the fragrance diffusing body 103 freely roll in the first chamber 101, the essential oil 104 can be impregnated on the fragrance diffusing body 103 in the first chamber 101, the Oswald ripening effect between the fragrance diffusing body 103 and the essential oil 104 can be generated to promote the volatilization of the essential oil 104, when the liquid level of the essential oil 104 in the capillary tube 105 is lower than the height of the capillary tube 105, the essential oil 104 cannot contact the fragrance diffusing body 103, the Oswald ripening effect cannot be generated, and the fragrance can be insufficient.

[0026] In the specific embodiment of the present application, the length of the capillary tube 105 is taken as a ruler, and the size of the inner diameter of the capillary tube 105 is changed to control the liquid level of the essential oil 104 in the capillary tube 105 above the length of the capillary tube 105.

[0027] The height of the liquid in the capillary tube 105 is calculated as follows:

[0028] In the capillary phenomenon, the positive and negative of the rising and falling height h of the liquid represent rising or falling, the rising of the wetting liquid, the acute contact angle, the falling of the non-wetting liquid, the obtuse contact angle, the rising height h = 2* surface tension coefficient*cos contact angle / liquid density*gravity acceleration g*capillary inner radius r.

[0029] The rising height of the liquid column is h = 2ycosθ / (ρgr), where γ = surface tension; θ = contact angle; ρ = liquid density; g = gravity acceleration; r = capillary inner radius, when θ > 90 degrees, which means that the meniscus is convex, and h < 0, which means that the fluid falls in the capillary tube.

[0030] In the test scheme: γ = 0.0728 mN / m, 1N = 1kg·m / s², θ = 20°, ρ = 1000 kg / m³, g = 9.8 m / s², r = 0.0004 m (0.8 mm inner diameter).

[0031] The liquid column height h = 2*0.0728*cos20° / 1000*9.8*0.0004

[0032] = 2*0.0728*0.94 / 3.92

[0033] = 0.0349 m

[0034] The height of 20mm is measured by a blood collection tube with an inner diameter of 1.6mm, and thus the surface tension of the essential oil can be calculated inversely.

[0035] Liquid column height = 20mm = 0.02m = 2*γ*cos20° / 1000*9.8*0.0008

[0036] γ = 1000*9.8*0.0008*0.02 / 2*cos20°

[0037] = 7.84*0.02 / 1.88

[0038] = 0.0834

[0039] Because the parameters of the height of the capillary liquid column are in a linear proportional relationship, under the condition that the contact angle, the liquid density, the gravity acceleration and the surface tension are the same, the height of the capillary liquid column and the radius of the capillary tube are inversely proportional. Assuming that the contact angle and the surface tension of the glass capillary tube and the stainless steel capillary tube are the same, the radius of the capillary tube can be converted.

[0040] Serial No. Capillary Type Capillary Gauge ID x Wall Thickness Length ID Liquid Column Height 1 Microhematocrit Tube Glass 20 microliters 1.6 x 0.5 25 mm 1.6 20 2 304 stainless steel capillary tube 1X0.35 25 mm 1 32 3 304 stainless steel capillary tube 1.2X0.4 25 mm 1.2 26.7 4 304 stainless steel capillary tube 0.8X0.2 25 mm 0.8 40 5 304 stainless steel capillary tube 1.4X0.4 25 mm 1.4 22.9

[0041] According to the table, when the radius r of the capillary tube is equal to 1.6mm, the height h of the liquid surface is 20mm, and when the radius r of the capillary tube is equal to 0.8mm, the height h of the liquid surface is 40mm. It can be concluded that the radius r of the capillary tube and the height h of the liquid surface are inversely proportional.

[0042] According to the table, when the length of the capillary tube 105 is 25mm, the inner diameter of the capillary tube 105 should not be greater than 1.2mm, so that the essential oil 104 can slowly rise from the second chamber 102 to the first chamber 101 by capillary effect. When the height of the essential oil 104 in the capillary tube 105 is higher than the length of the capillary tube 105, the essential oil 104 will form an upward convex arc surface at the top end of the capillary tube 105 in the first chamber 101. The fragrance diffusing body 103 can absorb the essential oil 104 by contacting the arc surface. The essential oil 104 after absorption will continue to form an upward convex arc surface slowly. When the fragrance diffusing body 103 in the first chamber 101 does not contact the capillary tube 105, the essential oil will stop seeping due to surface tension. The structure of the present application can achieve this effect in any posture, so that the seepage of the essential oil itself is controllable.

[0043] In the present application, the top end of the capillary tube 105 penetrates the interval between the first chamber 101 and the second chamber 102 and is not lower than the bottom of the first chamber 101, and the liquid level of the essential oil 104 in the second chamber 101 is higher than the bottom end of the capillary tube 105, so that the continuous slow release of the essential oil 104 is realized by the capillary effect, which perfectly solves the storage and slow release of the essential oil 104, and the first chamber 101 or the second chamber 102 can be heated by the human body or hands when it is carried, and the speed of the essential oil 104 flowing out or being recovered is controlled by the air pressure imbalance caused by thermal expansion and contraction.

[0044] Because the essential oil 104 can continuously seep out, the user does not need to worry about the amount of remaining essential oil, so the essential oil 104 can be stored in a completely light-proof environment, which solves the contradiction between the user's need to see the specific height of the essential oil 104 and the light sensitivity of the essential oil. The fragrance wood and the fragrance stone are often used in an open environment, and even if they are stored in a closed condition, they need to be maintained by dripping essential oil, and additional separate carrying of essential oil is inconvenient for the user. The present structure solves the convenience problem of simultaneously carrying the fragrance body 103 and the essential oil 104.

[0045] In use, the present application realizes the continuous lifting of the essential oil 104 to the first chamber 101 by the capillary effect, and when the essential oil 104 in the second chamber 102 is lowered after a period of use, the liquid level of the essential oil 104 in the capillary tube 105 lifted by the capillary effect will also be lowered, so that the liquid level of the essential oil 104 in the capillary tube 105 cannot be lifted to the first chamber 101.

[0046] In combination with the existing technical structure of the present application, the following technical effects are achieved, and the above problems can be solved by the following operation mode: the kettle body 1 is in a vertical and stationary state, the essential oil 104 can slowly rise into the first chamber 101 and be adsorbed on the fragrance body 103 for maturation effect, when the essential oil 104 rises relatively slowly or the essential oil 104 adsorbed on the fragrance body 103 is relatively small, resulting in insufficient fragrance, the kettle body 1 can be in a vertical state, so that one end of the capillary tube 105 is below the liquid level of the essential oil 104, the second chamber 102 is warmed by hand, the essential oil 104 is made to flow out by changing the air pressure, and the rising speed of the essential oil 104 is accelerated.

[0047] After the oil is accelerated to flow out by changing the air pressure in the second chamber 102 by warming with hands, the residual heat will make the essential oil 104 in the capillary tube 105 continue to rise, at this time the kettle 1 can be placed in a horizontal state, so that the capillary tube 105 in the second chamber 102 is not in the essential oil 104 but in the air, when the essential oil 104 remaining in the capillary tube 105 flows out, the oil flow will stop. After the oil flow stops, the kettle 1 can be placed in an inverted or inclined inverted state, and the first chamber 101 is warmed by hand. After tens of seconds, the kettle 1 is upright again, and the excess essential oil 104 in the first chamber 101 is sucked back into the second chamber 102 through the capillary tube 105 by the imbalance of air pressure, achieving the effect of reducing loss.

[0048] It should be noted that in the case where the kettle 1 is inverted, the second chamber 102 is on top, and the first chamber 101 is on the bottom, even if the capillary tube 105 is filled with liquid essential oil, under the condition that the air pressure in the first chamber 101 and the second chamber 102 is balanced, the essential oil 104 will not flow into the first chamber 101 to form penetration and leakage. The main reason is that the surface tension of the essential oil 104 at the top end of the capillary tube 105 and the adhesion of the essential oil 104 to the inner wall of the capillary tube 105 will prevent the essential oil 104 from flowing out due to gravity. The thinner the capillary tube 105, the stronger the adhesion. At the same time, in the vertical scenario where gravity is the strongest, the top end of the capillary tube 105 in the second chamber 102 will not be immersed in the essential oil liquid, only the essential oil remaining in the capillary tube 105. Because the length of the capillary tube 105 in the present application is lower than the height at which the essential oil 104 can rise in the capillary tube 105, the essential oil 104 in the capillary tube 105 will remain in the capillary tube 105 and not flow out under this condition.

[0049] It should be noted that in the case where the user heats the second chamber 102 with hands, causing a pressure difference between the first chamber 101 and the second chamber 102, the essential oil 104 will flow from the second chamber 102 to the first chamber 101 through the capillary tube 105 until the pressure balance at both ends, and vice versa. The specific essential oil flow calculation is as follows:

[0050] According to the constant pressure charlie law, under the condition of constant pressure, the change of gas volume is proportional to the change of temperature, V0 / V1=T0 / T1, the amount of essential oil overflow is the change of volume:

[0051] V δ =V1-V0=V0*(T1-T0) / T0

[0052] After the above values are brought in, the amount of essential oil overflowed under a specific temperature rise can be accurately calculated. Taking normal temperature as 24 degrees, using hand to raise temperature by 2 degrees, and air capacity in the oil cavity as 20 milliliters to calculate, V δ =V1-V0=V0*(T1-T0) / T0=20*2 / 24=1.67 milliliters, i.e. 1670 cubic millimeters, if it is a capillary tube with an inner diameter of 0.8 millimeters, according to a flow rate of 2 millimeters per second, the time required to pass through is: 1670 / (2*π*0.4 2 )=1662 seconds (flow = flow rate * pipe cross-sectional area), i.e. 27.7 minutes, because it is rarely used to heat for so long, so the overflow amount each time is limited. Referring to the application scene of using essential oil aromatherapy machine and expanding fragrance wood to expand fragrance, only two or three drops are needed each time to achieve a good fragrance expansion effect. 1 milliliter of essential oil is generally about 25 drops, so according to the calculation, 1 drop can be overflowed in about 1 minute, which can meet the actual needs.

[0053] The present application has the ability to continuously expand fragrance, not waste essential oil, and not bring additional inconvenience to the user under different use environments or different use states through accurate calculation and structural adjustment. At the same time, the structure of the present application also has good adjustability, and the essential oil 104 can be replaced with another variety of essential oil after it is used up. At the same time, the expanding fragrance wood or expanding fragrance stone can also be replaced according to the user's preference.

[0054] The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
