Atomizing device

Abstract

The present invention relates to an atomization device, belonging to the field of atomization application technology, and includes a liquid storage tank arranged below a piezoelectric ceramic atomization sheet. The piezoelectric ceramic atomization sheet has a central through hole. When the piezoelectric ceramic atomization sheet is working, under the high-frequency oscillation of the piezoelectric ceramic atomization sheet, the solution is sucked from the central through hole on the back side of the piezoelectric ceramic atomization sheet to the front side of the piezoelectric ceramic atomization sheet, so that the solution is quickly atomized on the front side of the piezoelectric ceramic atomization sheet, achieving a good atomization effect. The flow rate of the solution can be controlled by the size of the central through hole; secondly, the solution is placed on the back side of the piezoelectric ceramic atomization sheet, and the solution on the back side of the piezoelectric ceramic atomization sheet is sucked into the front side of the piezoelectric ceramic atomization sheet through the central through hole of the piezoelectric ceramic atomization sheet through the action of high-frequency oscillation, and then atomized, so as to avoid a large area of ​​solution covering the front side of the piezoelectric ceramic atomization sheet, thereby forming an excessive load and unable to atomize normally.

Description

Technical Field

[0001] The invention belongs to the technical field of atomization application, and in particular relates to an atomization device. Background Art

[0002] In daily life, as people's quality of life continues to improve, the requirements for air environment are becoming more and more important. Atomizers are mainly used in hotels, homes, offices, public environments, cars, medical protection keys, etc. When working, the liquid water molecules are thrown up and scattered, so that the water produces fine fog beads, giving people a visual fogging effect. In addition to atomizing water, a small amount of essential oils, liquid medicines and other solutions can also be added to the water, so that the essential oil molecules are emitted through water vapor to help eliminate brain fatigue, restore and relieve physical and mental balance, calm emotions, soothe sleep, and improve sleep quality. In the prior art, due to the high concentration of the solution, it is difficult for ultrasonic waves to break up the molecules of pure essential oils or solutions with a high concentration, and it is difficult to achieve separate atomization. In addition, if the concentrated solution covers too much on the surface of the atomizer or the liquid level is too deep, the atomization function cannot be achieved at all.

[0003] Therefore, whether it is possible to design a product that can atomize a solution with a higher concentration, has a good atomization effect, and is not affected by the concentration and viscosity of the liquid to overcome the above-mentioned defects is a technical problem that needs to be solved by technical personnel in this field. Utility Model Content

[0004] The present invention aims to provide an atomization device, which has a unique structural design and a central through hole in the center of a piezoelectric ceramic atomization piece. When the piezoelectric ceramic atomization piece is working, the solution is sucked from the back side of the piezoelectric ceramic atomization piece through the central through hole to the front side of the piezoelectric ceramic atomization piece, thereby realizing the function of rapid atomization. At the same time, the aperture size of the central through hole of the ceramic atomization piece is designed to control the flow rate of the solution, so that the front side of the piezoelectric ceramic atomization piece will not be completely covered by too much solution, resulting in poor atomization effect; in addition, the present invention is characterized in that under the action of the joint oscillation of the two sides of the piezoelectric ceramic atomization piece, the solution on the back side is sucked into the front side of the piezoelectric ceramic atomization piece through the piezoelectric ceramic atomization piece's own oscillation function, and a rapid atomization phenomenon is formed on the front side of the piezoelectric ceramic atomization piece.

[0006] An atomization device includes a liquid storage tank with a groove, and a piezoelectric ceramic atomization sheet with a first central through hole at the center is arranged in the groove. When the piezoelectric ceramic atomization sheet is working, the solution stored in the liquid storage tank is sucked into the front side of the piezoelectric ceramic atomization sheet through the first central through hole of the piezoelectric ceramic atomization sheet, so that the solution is quickly atomized on the front side of the piezoelectric ceramic atomization sheet.

[0021] The invention is further described below with reference to the accompanying drawings and examples:

[0022] An embodiment of the present invention is Figure 1 , Figure 2As shown, an atomization device comprises a piezoelectric ceramic atomization sheet 1 having a first central through hole 2 at the center thereof and a liquid storage tank 7 having a groove 8; the piezoelectric ceramic atomization sheet 1 is arranged in the groove 8, and its reverse side is in direct contact with the solution stored in the liquid storage tank 7. By arranging a through hole in the center of the piezoelectric ceramic atomization sheet 1, when the atomization device starts to work, under the action of the common oscillation of the two sides of the piezoelectric ceramic atomization sheet 1, the solution on the reverse side of the piezoelectric ceramic atomization sheet 1 is sucked from the central through hole 2 to the front side of the piezoelectric ceramic atomization sheet 1 through the self-oscillation function of the piezoelectric ceramic atomization sheet 1, and a rapid atomization phenomenon is formed on the front side of the piezoelectric ceramic atomization sheet 1, thereby realizing the function of rapid atomization. At the same time, the flow rate of the solution can be controlled by controlling the aperture size of the first central through hole 2 of the piezoelectric ceramic atomization sheet 1, so that the front side of the piezoelectric ceramic atomization sheet 1 will not be completely covered by the piezoelectric ceramic atomization sheet 1 due to excessive solution, resulting in poor atomization effect.

[0023] Furthermore, an upper metal block 3 and a lower metal block 5 are respectively provided on both sides of the piezoelectric ceramic atomization sheet 1. A second central through hole 4 is provided at the center of the upper metal block 3, and a third central through hole 6 is provided at the center of the lower metal block 5. The upper metal block 3 is placed above the piezoelectric ceramic atomization sheet 1 and fits tightly with the front side 10 of the piezoelectric ceramic atomization sheet 1 to form good conduction; the lower metal block 5 is placed below the piezoelectric ceramic atomization sheet 1 and fits tightly with the back side 11 of the piezoelectric ceramic atomization sheet 1 to form good conduction. There is no conduction between the upper metal block 3 and the lower metal block 5. When the piezoelectric ceramic atomizer sheet 1 is working, the solution in the cavity of the third central through hole 6 is under the high-frequency oscillation of the piezoelectric ceramic atomizer sheet 1. Since the lower metal block 5 is tightly fitted to the reverse side 11 of the piezoelectric ceramic atomizer sheet 1, the solution will be sucked from the first central through hole 2 of the piezoelectric ceramic atomizer sheet 1 to the front side 10 of the piezoelectric ceramic atomizer sheet 1, so that the solution is quickly atomized on the front side 10 of the piezoelectric ceramic atomizer sheet 1. In addition to being able to form conduction with the piezoelectric ceramic atomizer sheet 1, the upper metal block 3 and the lower metal block 5 also play a role in fixing and cooling the piezoelectric ceramic atomizer sheet 1, especially the cavity formed by the third central through hole 6 of the lower metal block 5 can also store part of the solution.

[0024] Furthermore, the centers of the circles of the first central through hole 2, the second central through hole 4 and the third central through hole 6 are on the same vertical line, and the apertures of the second central through hole 4 and the third central through hole 6 are both larger than the aperture of the first central through hole 2, so that the solution stored in the cavity of the third central through hole 6 is absorbed into the first central through hole 2 and atomized out through the cavity of the second central through hole 4.

[0025] Furthermore, a liquid injection hole 9 is provided on one side of the liquid storage bin 7, and the solution is injected into the groove 8 through the liquid injection hole 9, and the lower metal block 5 is placed in the groove 8 of the liquid storage bin 7, so that the cavity formed by the lower metal block 5 and the central through hole 6 can be filled with the solution.

[0026] Furthermore, liquid-conducting materials such as liquid-conducting cotton can be placed in the groove 8 to achieve functions such as liquid conduction and liquid storage.

[0027] Furthermore, the atomization frequency of the piezoelectric ceramic atomization sheet 1 is in the range of 1.5 MHZ to 4.5 MHZ.

[0028] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications made based on the present invention belong to the scope of protection claimed by the present invention.
