[0002] Nowadays, pure essential oil atomization devices usually use atomization methods such as microporous atomization, compression pump atomization and water-mixed aromatherapy atomization. In the microporous atomization method, a microporous atomizer comes into direct contact with the pure essential oil, and vibrates and compresses the pure essential oil to achieve the purpose of atomization. In the compression pump atomization method, the pure essential oil is dispersed by high-speed air obtained by compressing the air to achieve the effect of atomization and aromatherapy. In the water-mixed aromatherapy atomization process, pure essential oil is dropped or dissolved in water and forms a water-oil mixture, which is atomized by ultrasound, which diffuses essential oil particles in the water into the air.

[0032] As shown in Figures 1 and 2, a preferred embodiment of the present disclosure provides a pure essential oil atomizing device, comprising a bottle body 1, a housing 2, a guide cotton 3 and an ultrasonic atomizing sheet 4.

[0033] The bottle body 1 is provided therein with a pure essential oil chamber 11, and the bottle body 1 is provided with an opening 12 in communication with the pure essential oil chamber 11. The housing 2 is detachably connected to the bottle body 1, and the housing 2 covers the opening 12. The housing 2 is provided therein with an atomizing chamber 21, and the housing 2 is provided with an atomizing outlet 22 in communication with the atomizing chamber 21. The ultrasonic atomizing sheet 4 is provided in the atomizing chamber 21, and the atomizing sheet Ultrasonic 4 is provided with an atomization plane 41. One end of the guide cotton 3 is attached to the atomization plane 41, and one end of the guide cotton 3 encircles a center of the atomization plane 41, which refers to a geometric center of the atomization plane. The other end of the guide cotton 3 extends through the housing 2 to the pure essential oil chamber 11.

[0034] In this solution, the ultrasonic atomizing sheet 4 directly atomizes the pure essential oil. The pure essential oil atomizing device must avoid direct contact between the pure essential oil and the ultrasonic atomizing sheet 4, so as to avoid the problem of poor atomizing efficiency and poor atomizing effect caused by uneven supply of pure essential oil. For this purpose, the guide cotton 3 serves as a pure essential oil passage to guide the pure essential oil into the pure essential oil chamber 11 until it contacts the atomizing plane 4L. The design strengthens the atomizing effect, improves the atomizing efficiency, and effectively solves problems such as leakage and noise during use. As shown in Figures 1, 7 and 8, the ultrasonic atomizing sheet 4 can be arranged in any direction, such as inverted ([Fig.l]), vertical ([Fig.7]), or horizontal ([Fig.8]). In the reverse direction, a contact surface of the ultrasonic atomizing sheet with the pure essential oil is facing downward. In the horizontal direction, the contact surface of the ultrasonic atomizing sheet with the pure essential oil is facing upward. The placement directions vary to adapt to different device usage scenarios, which enriches the diversity of the devices.

[0035] As shown in Figures 5 and 6, in some improvement solutions of the present disclosure, the projection of the guide cotton 3 onto the atomization plane 41 encircles the center of the atomization plane 41, and a central angle of an arc of the projection is N°, 180 < N < 360. One end of the guide cotton 3 is firmly attached to the atomization plane 41 of the ultrasonic atomization sheet 4 in a semicircular or completely circular manner, and the other end of the guide cotton 3 is in contact with the pure essential oil in the pure essential oil chamber 11. Through the pure essential oil passage, the pure essential oil in the bottle body 1 is introduced into the ultrasonic atomization sheet 4, avoiding direct contact between the pure essential oil and the ultrasonic atomization sheet 4.

[0036] As shown in Figures 3 and 4, in some improvement solutions of the present disclosure, the atomization plane 41 is circular with a radius of R mm. A maximum distance between the projection of the guide cotton 3 on the atomization plane 41 and the center of the atomization plane 41 is L mm, and a minimum distance between the projection of the guide cotton on the atomization plane and the center of the atomization plane 41 is G mm, 0.3 < G / R < L / R < 0.9. Through the passage of essential oil pure, a projection area of ​​the guide cotton 3 on the atomization plane 41, that is, a contact area between the guide cotton 3 and the atomization plane 41, is limited. In this way, the pure essential oil is distributed more evenly on the atomization plane 41, which strengthens the atomization effect and improves the atomization efficiency.

[0037] In some improvement solutions of the present disclosure, one end of the guide cotton 3 may also be provided at a wave node point of the ultrasonic atomizing sheet 4. Since the guide cotton 3 is provided at the wave node point of the ultrasonic atomizing sheet 4, the vibration interference of the guide cotton 3 on the ultrasonic atomizing sheet is reduced, so that the ultrasonic atomizing sheet 4 can achieve an optimal amplitude. In addition, since the guide cotton 3 is provided at the wave node point of the ultrasonic atomizing sheet 4, it can be prevented from burning.

[0038] In some improvement solutions of the present disclosure, an atomization temperature of the ultrasonic atomizing sheet 4 is T °C, 80 < T < 160. An experiment shows that the viscosity of the pure essential oil decreases with increasing temperature, and the ultrasonic atomizing sheet 4 atomizes a low-viscosity pure essential oil more easily. Table 1 shows the viscosity variations of a water-based oil at different temperatures.

[0039] Table 1 Viscosities of pure water-based essential oil at different temperatures Temperature (°C) Viscosity (mPa*s) 10 1.308 20 1.002 30 0.7978 40 0.6531 50 0.5471 60 0.4658 70 0.4044 80 0.3550 90 0.3150 100 0.2822

[0040] It can be observed from the above table that a higher temperature results in a lower viscosity of the pure essential oil. In one embodiment of the present disclosure, the temperature of the ultrasonic atomizing sheet 4 is regulated to rapidly raise the temperature of the essential oil pure essential oil, which reduces the viscosity of the pure essential oil. Specifically, in the present disclosure, a heating rate of the ultrasonic atomizing sheet 4 is regulated to increase the temperature of the ultrasonic atomizing sheet 4 in a short period of time. The high temperature of the ultrasonic atomizing sheet 4 can quickly heat the pure essential oil transported through the pure essential oil passage. By increasing the temperature of the pure essential oil, the viscosity of the pure essential oil is reduced, which reduces the difficulty of atomizing the pure essential oil with the ultrasonic atomizing sheet 4.In addition, when the temperature of pure essential oil increases, the molecular activity of pure essential oil is enhanced, and the molecular force and surface tension of pure essential oil are reduced, which accelerates the atomization of pure essential oil, reduces the delay time of atomization start, and improves the user experience.

[0041] In some improvement solutions of the present disclosure, the guide cotton 3 comprises a first guide cotton 31 and a second guide cotton 32 connected to each other. The first guide cotton 31 is attached to the atomization plane 41, and the second guide cotton 32 extends through the housing 2 to the pure essential oil chamber 11. The first guide cotton 31 is made of a high-temperature resistant material. Due to the atomization of the pure essential oil through high temperature, as the use and atomization time increases, the first guide cotton 31 firmly attached to one end of the ultrasonic atomizing sheet 4 will be burned by the high temperature generated during the operation of the ultrasonic atomizing sheet 4, resulting in poor atomization efficiency and poor atomization effect.Therefore, the present disclosure uses the first guide cotton made of a high temperature resistance material to avoid damage to the pure essential oil passage caused by the high temperature generated by the ultrasonic atomizing sheet 4, thereby stabilizing the long-term pure essential oil supply to the surface of the ultrasonic atomizing sheet 4. Specifically, the first guide cotton 31 may be made of a glass fiber, a porous ceramic, or another high temperature resistance guide material.

[0042] The second guide cotton 32 is made of a fast guide material that can quickly transfer the pure essential oil to the first guide cotton 31, ensuring a stable supply of pure essential oil. Specifically, the second guide cotton 32 may be made of a pure cotton material.

[0043] In some improvement solutions of the present disclosure, the guide cotton 3 may also contact the ultrasonic atomizing sheet through a porous ceramic or other material as an intermediate medium for achieve pure essential oil transfer. Specifically, in the present disclosure, when porous ceramic is used as an intermediate medium, due to its high temperature resistance, it can prevent the high temperature of the ultrasonic atomizing sheet 4 from burning the guide cotton 3, thereby reducing the difficulty of selecting the guide cotton 3.

[0044] In some improvement solutions of the present disclosure, the opening 12 of the bottle body 1 faces upward, and the housing 2 covers the opening 12 from top to bottom and is screwed onto the bottle body 1. A lower portion of the housing 2 is provided with an air hole 23 which communicates the atomization chamber 21 with the pure essential oil chamber 11. When the pure essential oil is transported to the housing 2 via the second guide cotton 32 in the bottle body 1, a negative pressure is generated in the pure essential oil chamber 11 due to the reduction of the pure essential oil. The negative pressure will cause an internal pressure of the pure essential oil chamber 11 to be lower than an external air pressure, making it impossible to continuously guide the pure essential oil.Therefore, the air hole 23 in communication with an internal space of the pure essential oil chamber 11 is provided at the lower part of the housing 2, so that the air pressure inside the pure essential oil chamber 11 is balanced with the air pressure outside the bottle body 1, achieving a continuous guiding effect of pure essential oil. In addition, accumulation of pure essential oil may occur at the lower part of the atomizing chamber 21 after long-term atomization. The air hole 23 allows accumulated pure essential oil to flow back into the pure essential oil chamber 11, achieving reuse of the pure essential oil.

[0045] In further improvement solutions of the present disclosure, the second guide cotton 32 is hollow. Since the second guide cotton 32 is hollow, an air exchange can be performed inside the second guide cotton 32 to balance the air pressure inside the pure essential oil chamber 11 with the air pressure outside the bottle body 1, achieving a continuous transfer effect of pure essential oil.

[0046] In some improvement solutions of the present disclosure, the housing 2 is further provided with an air chamber 24. The housing 2 is provided with an air inlet 25. The air inlet 25 communicates with the air chamber 24. The atomizing chamber 21 communicates with the atomizing outlet 22 via the air chamber 24. The spray plane 41 is oriented toward the air chamber 24. Air enters through the air inlet 25, mixes with a mist of pure essential oil in the air chamber 24, and is then blown out through the atomizing outlet 22, alleviating the problem of the atomizer, i.e., poor atomizing effect caused by the fluctuation of pure essential oil mist.

[0047] In some improvement solutions of the present disclosure, a cross-section of a wall of the air chamber 24 is circular to avoid airflow obstruction, bouncing and other impacts within the air chamber 24. Specifically, the air chamber 24 may be a circular chamber.

[0048] In some improvement solutions of the present disclosure, the atomizing outlet 22 is provided at a top portion of the housing 2. The air inlet 25 is provided at a side wall of the housing 2, and the air inlet 25 and the atomizing outlet 22 are respectively arranged on the left and right sides of the housing 2. The air inlet and the atomizing outlet 22 form convection, helping air to enter through the air inlet 25 and then circulate in the air chamber 24 to completely mix with the pure essential oil mist before being blown out.

[0049] Overall, the embodiment of the present disclosure provides a pure essential oil atomizing device. The ultrasonic atomizing sheet 4 directly atomizes the pure essential oil. The pure essential oil atomizing device must avoid direct contact between the pure essential oil and the ultrasonic atomizing sheet 4, so as to avoid the problem of poor atomizing efficiency and poor atomizing effect caused by non-uniform supply of pure essential oil.For this purpose, the guide cotton 3 serves as a pure essential oil passage to guide the pure essential oil into the pure essential oil chamber 11 until it contacts the atomization plane 4L. The design strengthens the atomization effect, improves the atomization efficiency, effectively solves problems such as leakage and noise during use, and prevents the supply of the pure essential oil passage from being affected by negative pressure.

[0050] The foregoing implementations are only preferred implementations of the present disclosure. It should be noted that various improvements and replacements may further be made by a person skilled in the art without departing from the technical principle of the present disclosure, and such improvements and replacements should also be considered within the scope of protection of the present disclosure.
