These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
[0032] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides an oil atomizing device, comprising: a bottle body 1, a shell 2, an oil-guiding cotton 3, and an ultrasonic atomizing plate 4.
[0033] The bottle body 1 has an oil chamber 11 inside, and the bottle body 1 has an opening 12 that communicates with the oil chamber 11. The shell 2 is detachably connected to the bottle body 1, and the shell 2 covers the opening 12. The shell 2 has an atomizing chamber 21 inside, and the shell 2 has an atomizing outlet 22 that communicates with the atomizing chamber 21. The ultrasonic atomizing plate 4 is disposed in the atomizing chamber 21. The ultrasonic atomizing plate 4 has an atomizing plane 41. One end of the oil-guiding cotton 3 is attached to the atomizing plane 41, and one end of the oil-guiding cotton 3 is arranged around the center of the atomizing plane 41. The other end of the oil-guiding cotton 3 extends through the shell 2 into the oil chamber 11.
[0034] This solution uses an ultrasonic atomizing plate 4 to directly atomize the oil. To avoid uneven oil supply leading to poor atomization efficiency and effect due to direct contact between the atomized oil and the ultrasonic atomizing plate 4, which could result in uneven oil supply, an oil-guiding cotton 3 is used as an oil path to guide the oil in the oil chamber 11 to contact the atomizing plane 41, thereby enhancing the atomization effect, improving atomization efficiency, and effectively solving problems such as leakage and noise during use. Figure 1 , Figure 7 , Figure 8 As shown, the ultrasonic atomizing plate 4 can be placed in an inverted position (illustrated). Figure 1 ), vertical (illustrated) Figure 7 ), horizontal (illustrated) Figure 8 In any way, such as placement, different placement methods can be used to adapt to different product usage scenarios, thus enriching product diversity.
[0035] like Figure 5 and Figure 6As shown, in some improvements of this application, the projection of the oil-guiding cotton 3 onto the atomizing plane 41 has a central angle of N° around the center of the atomizing plane 41, satisfying 180≤N≤360. One end of the oil-guiding cotton 3 can be tightly attached to the atomizing plane 41 of the ultrasonic atomizing plate 4 in a semi-circular or full-circular manner, while the other end of the oil-guiding cotton 3 contacts the liquid in the oil chamber 11. The liquid in the bottle 1 is introduced into the ultrasonic atomizing plate 4 via an oil passage, avoiding direct contact between the liquid and the ultrasonic atomizing plate 4.
[0036] like Figure 3 and Figure 4 As shown, in some improvements of this application, the atomizing plane 41 is circular with a radius of R mm; the maximum distance between the projection of the oil-guiding cotton 3 on the atomizing plane 41 and the center of the atomizing plane 41 is L mm, and the maximum distance between the oil-guiding cotton 3 and the edge of the atomizing plane 41 is G mm, wherein the following condition is satisfied: 0.3≤G / R≤L / R≤0.9. By using an oil-guiding method, and limiting the projection of the oil-guiding cotton 3 on the atomizing plane 41, i.e., the contact area between the oil-guiding cotton 3 and the atomizing plane 41, the oil can be spread more evenly on the atomizing plane 41, thereby enhancing the atomization effect and improving the atomization efficiency.
[0037] In some improvements of this application, one end of the oil-guiding cotton 3 can also be set at the wave node position of the ultrasonic atomizing plate 4. Setting the oil-guiding cotton 3 at the wave node position of the ultrasonic atomizing plate 4 reduces the vibration interference of the oil-guiding cotton 3 on the ultrasonic atomizing plate, so that the ultrasonic atomizing plate 4 can achieve the optimal amplitude. In addition, placing the oil-guiding cotton 3 at the wave node position of the ultrasonic atomizing plate 4 can also prevent the oil-guiding cotton from burning.
[0038] In some improvements of this application, the atomization temperature of the ultrasonic atomizing plate 4 is T℃, satisfying: 80≤T≤160. Experiments have shown that the viscosity of the oil decreases with increasing temperature, and the ultrasonic atomizing plate 4 more easily atomizes low-viscosity oils. Table 1 shows the viscosity changes of a certain oil at different temperatures:
[0039] Table 1: Viscosity of a certain oil at different temperatures
[0040]
[0041] As can be seen from the table above, the higher the temperature, the lower the viscosity of the oil. In one embodiment of this application, by controlling the temperature of the ultrasonic atomizing plate 4, the oil is rapidly heated to reduce its viscosity. Specifically, in this application, the temperature of the ultrasonic atomizing plate 4 is increased rapidly in a short time by controlling the heating rate of the ultrasonic atomizing plate 4. The high temperature of the ultrasonic atomizing plate 4 can rapidly heat the oil transmitted from the oil path, thereby increasing the oil's temperature and reducing its viscosity, thus reducing the difficulty of atomization by the ultrasonic atomizing plate 4. Furthermore, the increased oil temperature enhances the molecular activity of the oil, reduces the interaction forces and surface tension of the oil molecules, thereby accelerating atomization, reducing the delay time of atomization start-up, and improving the user experience. When the heating rate is less than 1 t / s, the effect on the oil temperature is significant. When the heating rate is between 1 and 5 t / s, the effect on the oil temperature is significant but gradually slows down. When the heating rate is greater than 5 t / s, the effect on the oil temperature tends to stabilize. Therefore, specifically, the heating rate of the ultrasonic atomizing plate 4 can be selected as 1~5t / s.
[0042] In some improvements of this application, the oil-guiding cotton 3 includes a first guide cotton 31 and a second guide cotton 32 connected to each other. The first guide cotton 31 is fitted to the atomizing plane 41, and the second guide cotton 32 passes through the housing 2 and extends into the oil cavity 11. The first guide cotton 31 is made of a high-temperature resistant material. Because high temperatures are used to atomize the oil, with increasing use and atomization time, the first guide cotton 31, which is in close contact with one end of the ultrasonic atomizing plate 4, will be scorched by the high temperature generated during the operation of the ultrasonic atomizing plate 4, resulting in poor atomization efficiency and effect. Therefore, using a high-temperature resistant material to make the first guide surface can prevent the ultrasonic atomizing plate 4 from generating high temperatures that could damage the oil path, thereby ensuring a long-term stable supply of oil to the surface of the ultrasonic atomizing plate 4. Specifically, the first guide cotton 31 can be made of glass fiber oil-guiding cotton 3, porous ceramic oil-guiding material, or other high-temperature resistant oil-guiding materials.
[0043] The second guide cotton 32 is made of a material that guides oil quickly, which can quickly transfer the oil to the first guide cotton 31, thereby ensuring a stable oil supply.
[0044] In some improvements of this application, the oil-wicking cotton 3 can also use porous ceramics or other media as intermediate media to contact the ultrasonic atomizing plate to achieve oil transfer. Specifically, in this application, when porous ceramics are used as intermediate media, the porous ceramics themselves have high temperature resistance, which can prevent the high temperature of the ultrasonic atomizing plate 4 from burning the oil-wicking cotton 3, thereby reducing the difficulty of selecting the oil-wicking cotton 3.
[0045] In some improvements of this application, the opening 12 of the bottle 1 faces upward, and the shell 2 seals the opening 12 from top to bottom and is spirally connected to the bottle 1; the bottom of the shell 2 has a vent 23 that connects the atomizing chamber 21 and the oil chamber 11. When the oil is transported upward to the shell 2 through the second guide cotton 32 in the bottle 1, the liquid in the oil chamber 11 decreases, resulting in a negative pressure phenomenon. This causes the air pressure inside the oil chamber 11 to be lower than the external atmospheric pressure, making it impossible to continuously guide the oil. Therefore, by opening a vent 23 at the bottom of the shell 2 and connecting it to the oil chamber 11, the air pressure inside the oil chamber 11 and outside the bottle 1 can be balanced, achieving the effect of continuous oil guiding. At the same time, due to long-term atomization, oil will accumulate at the bottom of the atomizing chamber 21. The vent 23 allows the accumulated oil to flow back into the oil chamber 11, achieving the reuse of the oil.
[0046] In some other improvements of this application, the interior of the second guide cotton 32 is hollow. By hollowing out the interior of the second guide cotton 32, air exchange can be carried out inside the second guide cotton 32, resulting in the balance of air pressure inside the oil chamber 11 and outside the bottle 1, thus achieving the effect of continuous oil guiding.
[0047] In some improvements of this application, the housing 2 is further provided with an air cavity 24, and the housing 2 has an air inlet 25. The air inlet 25 is connected to the air cavity 24, and the atomizing chamber 21 is connected to the atomizing outlet 22 through the air cavity 24. The atomizing plane 41 is arranged facing the air cavity 24. Air enters from the air inlet 25, mixes with the oil mist in the air cavity 24, and is then blown out from the atomizing outlet 22, which can reduce the phenomenon of poor mist output caused by the fluctuation of mist from the atomizing plate.
[0048] In some improvements of this application, the cross-sectional wall of the air cavity 24 is circular, which can avoid structures that affect airflow, such as airflow obstruction or rebound, from occurring within the air cavity 24. Specifically, the air cavity 24 can be an arc-shaped cavity.
[0049] In some improvements of this application, the atomizing outlet 22 is located at the top of the housing 2, and the air inlet 25 is located on the side wall of the housing 2, with the air inlet 25 and the atomizing outlet 22 respectively located on the left and right sides of the housing 2. This allows the air inlet and the atomizing outlet 22 to form convection, facilitating the air to enter through the air inlet 25, circulate within the air cavity 24, fully mix with the oil mist, and then be blown out.
[0050] In summary, the embodiments of the present invention provide an oil atomizing device that uses an ultrasonic atomizing plate 4 to directly atomize the oil. To avoid the oil product directly contacting the ultrasonic atomizing plate 4, which could lead to uneven oil supply and poor atomization efficiency and effect, an oil-guiding cotton 3 is used as an oil path to guide the oil in the oil cavity 11 to contact the atomizing plane 41, thereby enhancing the atomization effect and improving the atomization efficiency. It can also effectively solve problems such as leakage and noise during use, and will not cause negative pressure to affect the oil supply.
[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
