The present application claims the benefit of Chinese Patent Application No. 202310682163.1 filed on Jun. 9, 2023, the contents of which are incorporated herein by reference in their entirety.
The present disclosure relates to the technical field of atomization devices, and in particular to a pure essential oil atomization device.
At present, 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 method, the pure essential oil is dropped into or dissolved in water and form a water-oil mixture, which is atomised by ultrasound, thereby diffusing essential oil particles in the water into the air.
The microporous atomization method has problems such as leakage and short service life, and cannot atomize high-viscosity pure essential oils. Although the compression pump atomization method can atomize high-viscosity pure essential oils, the compression pump used in it has problems such as complex structure, large volume, and high working noise. The water mixed aromatherapy atomization method has the problem of pure essential oil contamination.
Therefore, the current pure essential oil atomization devices need improvement.
An objective of the present disclosure is to design a pure essential oil atomization device, so as to solve the aforementioned problems.

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 communicated 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 atomization outlet 22 communicated with the atomizing chamber 21. The ultrasonic atomization sheet 4 is provided in the atomizing chamber 21, and the ultrasonic atomization sheet 4 is provided with an atomizing plane 41. One end of the guide cotton 3 is attached to the atomizing plane 41, and the one end of the guide cotton 3 surrounds a center of the atomizing plane 41, which refers to a geometric center of the atomizing plane. The other end of the guide cotton 3 extends through the housing 2 to the pure essential oil chamber 11.
In this solution, the ultrasonic atomization sheet 4 directly atomizes the pure essential oil. The pure essential oil atomization device needs to avoid direct contact between the pure essential oil and the ultrasonic atomization sheet 4, so as to avoid the problem of poor atomization efficiency and poor atomization effect caused by uneven pure essential oil supply. For this purpose, the guide cotton 3 serves as a pure essential oil passage to guide the pure essential oil in the pure essential oil chamber 11 to come into contact with the atomizing plane 41. The design enhances the atomization effect, improves the atomization efficiency, and effectively solves problems such as leakage and noise during use. As shown in

In some improvement solutions of the present disclosure, the one end of the guide cotton 3 can also be provided at a point of wave nodes of the ultrasonic atomization sheet 4. Since the guide cotton 3 is provided at the point of wave nodes of the ultrasonic atomization sheet 4, the vibration interference of the guide cotton 3 on the ultrasonic atomization sheet is reduced, such that the ultrasonic atomization sheet 4 can achieve optimal amplitude. In addition, since the guide cotton 3 is provided at the point of wave nodes of the ultrasonic atomization sheet 4, it can be prevented from burning.
In some improvement solutions of the present disclosure, an atomization temperature of the ultrasonic atomization sheet 4 is T° C., 80≤T≤160. An experiment shows that the viscosity of the pure essential oil decreases with the increase of temperature, and the ultrasonic atomization sheet 4 is easier to atomize a low-viscosity pure essential oil. Table 1 shows viscosity changes of a water-based oil at different temperatures.
It can be seen from the above table that a higher temperature leads to a lower viscosity of the pure essential oil. In an embodiment of the present disclosure, the temperature of the ultrasonic atomization sheet 4 is controlled to quickly raise the temperature of the pure essential oil, thereby reducing the viscosity of the pure essential oil. Specifically, in the present disclosure, a heating rate of the ultrasonic atomization sheet 4 is controlled to increase the temperature of the ultrasonic atomization sheet 4 in a short period of time. The high temperature of the ultrasonic atomization 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, thereby reducing the difficulty of atomizing the pure essential oil with the ultrasonic atomization sheet 4. In addition, when the temperature of the pure essential oil increases, the molecular activity of the pure essential oil is enhanced, and the molecular force and surface tension of the pure essential oil are reduced, thereby accelerating the atomization of the pure essential oil, reducing the delay time of atomization start, and improving the user experience.
In some improvement solutions of the present disclosure, the guide cotton 3 includes a first guide cotton 31 and a second guide cotton 32 connected to each other. The first guide cotton 31 is attached to the atomizing 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 resistance material. Due to the atomization of the pure essential oil through a high temperature, as the use and atomization time increase, the first guide cotton 31 tightly attached to one end of the ultrasonic atomization sheet 4 will be burnt by the high temperature generated during the operation of the ultrasonic atomization 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 prevent damage to the pure essential oil passage caused by the high temperature generated by the ultrasonic atomization sheet 4, thereby stabilizing the long-term pure essential oil supply to the surface of the ultrasonic atomization sheet 4. Specifically, the first guide cotton 31 can be made of a glass fiber, a porous ceramic, or other high temperature resistance guide material.
The second guide cotton 32 is made of a quick guide material that can quickly transfer the pure essential oil to the first guide cotton 31, ensuring stable pure essential oil supply. Specifically, the second guide cotton 32 can be made of a pure cotton material.
In some improvement solutions of the present disclosure, the guide cotton 3 can also contact the ultrasonic atomization sheet through a porous ceramic or other material as an intermediate medium to achieve pure essential oil transfer. Specifically, in the present disclosure, when the porous ceramic is used as the intermediate medium, due to its high temperature resistance, it can prevent the high temperature of the ultrasonic atomization sheet 4 from burning the guide cotton 3, thereby reducing the difficulty of selecting the guide cotton 3.
In some improvement solutions of the present disclosure, the opening 12 of the bottle body 1 is oriented upwards, and the housing 2 covers the opening 12 from top to bottom and is screwed to the bottle body 1. A bottom part of the housing 2 is provided with an air hole 23 that communicates the atomizing chamber 21 with the pure essential oil chamber 11. When the pure essential oil is transported up to the housing 2 through 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 communicated with an internal space of the pure essential oil chamber 11 is provided at the bottom part of the housing 2, such 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 pure essential oil guiding effect. In addition, pure essential oil accumulation may occur at the bottom 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 the reuse of the pure essential oil.
In other improvement solutions of the present disclosure, the second guide cotton 32 is hollow. Since the second guide cotton 32 is hollow, air exchange can be carried out 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 pure essential oil transfer effect.
In some improvement solutions of the present disclosure, the housing 2 is further provided therein with an air chamber 24. The housing 2 is provided with an air inlet 25. The air inlet 25 is communicated with the air chamber 24. The atomizing chamber 21 is communicated with the atomization outlet 22 through the air chamber 24. The atomizing plane 41 is oriented towards the air chamber 24. The air enters from the air inlet 25, mixes with a pure essential oil mist in the air chamber 24, and then blows out from the atomization outlet 22, alleviating the problem of the atomizer, that is, poor atomization effect caused by the fluctuation of the pure essential oil mist.
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, rebound, and other impacts inside the air chamber 24. Specifically, the air chamber 24 can be a circular chamber.
In some improvement solutions of the present disclosure, the atomization outlet 22 is provided at a top part 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 atomization outlet 22 are respectively arranged on left and right sides of the housing 2. The air inlet and the atomization outlet 22 form convection, facilitating the air to enter from the air inlet 25 and then circulate in the air chamber 24 to fully mix with the pure essential oil mist before blowing out.
Overall, the embodiment of the present disclosure provides a pure essential oil atomization device. The ultrasonic atomization sheet 4 directly atomizes the pure essential oil. The pure essential oil atomization device needs to avoid direct contact between the pure essential oil and the ultrasonic atomization sheet 4, so as to avoid the problem of poor atomization efficiency and poor atomization effect caused by uneven pure essential oil supply. For this purpose, the guide cotton 3 serves as a pure essential oil passage to guide the pure essential oil in the pure essential oil chamber 11 to come into contact with the atomizing plane 41. The design enhances the atomization effect, improves 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 a negative pressure.
The above are only preferred implementations of the present disclosure. It should be noted that several improvements and replacements may further be made by a person of ordinary skill in the art without departing from the technical principle of the present disclosure, and such improvements and replacements should also be deemed as falling within the protection scope of the present disclosure.
