A low-power piezoelectric ceramic atomizer

Abstract

The present invention relates to a low-power piezoelectric ceramic atomizer sheet, wherein an electrode layer, a protective layer, and a conductive layer of the same shape are respectively designed on the front and back sides of the piezoelectric ceramic sheet; the electrode layer covers the surface of the piezoelectric ceramic sheet, and then the protective layer is covered on the electrode layer, and finally the conductive layer is covered on the protective layer. A circular electrode, a conductive circular ring, and an electrode connecting wire are designed on the electrode layer, and the circular electrode is connected to the conductive layer through the electrode connecting wire and the conductive circular ring to form mutual conduction. The area of ​​the circular electrode is smaller than the area of ​​the protective layer, so that the protective layer forms a good protective effect on the circular electrode. At the same time, the protective layer can isolate the circular electrode of the electrode layer from the conductive layer. The circular electrode is an effective oscillation electrode in the piezoelectric ceramic atomizer sheet. After the conductive layer is isolated by the protective layer, it does not form an effective oscillation electrode with the circular electrode, and only forms an effective static capacitance for the piezoelectric ceramic atomizer sheet.

[0002] In daily life, piezoelectric ceramic atomizers are mainly used in garden atomization, household heating, medical atomization, beauty atomization, industrial dust removal, aromatherapy, etc. Piezoelectric ceramic atomizers use a certain stable voltage to oscillate a frequency. This oscillation frequency does not cause any harm to humans and animals. Through the high-frequency oscillation of the atomizer, solutions such as water and essential oils are atomized into naturally flowing fine particles and diffused into the air of the surrounding environment, achieving good humidification and aromatherapy effects. If you want to increase the atomization volume of the product during use, it is mainly achieved by increasing the power of the machine, but increasing the power will have a certain impact on the product's service life, use effect, use stability, matching of peripheral circuits, etc., and simply increasing power consumption to achieve the goal is not advocated in our lives.

[0011] Preferably, the piezoelectric ceramic sheet has a diameter of 8.0 to 30.0 mm and a thickness of 0.6 to 1.5 mm.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and examples:

[0026] An embodiment of the present invention is Figure 1 , Figure 2 , Figure 3 As shown, it includes a piezoelectric ceramic sheet 1, and a first electrode layer 2, a first protective layer 3, and a first conductive layer 4 are provided on the front surface of the piezoelectric ceramic sheet 1; the first electrode layer 2 covers the upper surface of the piezoelectric ceramic sheet 1, the first protective layer 3 covers the first electrode layer 2, and finally the first conductive layer 4 covers the first protective layer 3. The first electrode layer 2 is provided with a first circular electrode 9, a first conductive ring 8, and a first electrode connecting line 10. The first circular electrode 9 is connected to the first conductive ring 8 through the first electrode connecting line 10, and the first conductive ring 8 is connected to the outermost first conductive layer 4, so that the first circular electrode 9 is connected to the first conductive layer 4. Similarly, a second electrode layer 5, a second protective layer 6, and a second conductive layer 7 are provided on the reverse surface of the piezoelectric ceramic sheet 1. The second electrode layer 5 covers the lower surface of the piezoelectric ceramic sheet 1, the second protective layer 6 covers the second electrode layer 5, and finally the second conductive layer 7 covers the second protective layer 6. The second electrode layer 5 is provided with a second circular electrode 12, a second conductive ring 11, and a second electrode connecting line 13. The second circular electrode 12 is connected to the second conductive ring 11 through the second electrode connecting line 13. The second conductive ring 11 is connected to the outermost second conductive layer 7, so that the second circular electrode 12 is connected to the second conductive layer 7. The feature of the present invention is that the outer layer of the first protective layer 3 and the second protective layer 6 is also covered with a first conductive layer 4 and a second conductive layer 7. The static capacitance formed by the first conductive layer 4 on the front side of the piezoelectric ceramic sheet 1 and the second conductive layer 7 on the back side of the piezoelectric ceramic sheet 1 can achieve the effects of increasing the atomization amount of the product, achieving rapid atomization, reducing atomization splashing, and improving water cut-off sensitivity, avoiding the problem of mismatch with the peripheral circuit and increased power caused by directly expanding the area of ​​the first circular electrode 9 and the second circular electrode 12. Secondly, although the conductive layer is connected to the circular electrode, it is isolated by the protective layer and does not serve as an effective oscillation electrode. It does not interfere with or restrain the circular electrode, but can stimulate the oscillation effect of the circular electrode. Thirdly, after the conductive layer does not serve as an effective oscillation electrode, the area of ​​the circular electrode can be appropriately reduced, thereby reducing the power consumption of the piezoelectric ceramic atomizer 1.

[0027] Specifically, the first electrode layer 2, the first conductive layer 4, the second electrode layer 5 and the second conductive layer 7 are preferably printed with silver paste on the piezoelectric ceramic sheet 1, but can also be printed with other conductive pastes, which are not specifically limited here. The first protective layer 3 and the second protective layer 6 are preferably glass glaze layers, but can also be made of other materials with protective properties such as corrosion resistance and acid and alkali resistance, which are not specifically limited here, so that the protective layer has a good protective effect on the circular electrode, and the protective layer can isolate the circular electrode from the conductive layer.

[0028] Specifically, the piezoelectric ceramic sheet 1 has a diameter of 8.0 to 30.0 mm and a thickness of 0.6 to 1.5 mm.

[0029] Specifically, the centers of the first circular electrode and the second circular electrode are on the same vertical line.

[0030] Specifically, the area of ​​the first circular electrode 9 is smaller than the area of ​​the first protective layer 3, and the area of ​​the second circular electrode 12 is smaller than the area of ​​the second protective layer 6, so that the protective layer can provide good protection for the circular electrode. At the same time, the protective layer can isolate the circular electrode of the electrode layer from the conductive layer. After the conductive layer is isolated by the protective layer, it does not form an effective oscillation electrode with the circular electrode, but only forms an effective static capacitor for the piezoelectric ceramic atomizer.

[0031] Specifically, the area of ​​the first protective layer 3 is smaller than that of the first conductive layer 4, the area of ​​the second protective layer 6 is smaller than that of the second conductive layer 7, and the area of ​​the conductive layer is larger than that of the protective layer, so that the conductive layer and the conductive ring can be well connected.

[0032] Specifically, the orthographic projections of the first electrode connecting line and the second electrode connecting line do not overlap.

[0033] Experiments have shown that by designing a conductive layer on the protective layers on both sides of the piezoelectric ceramic atomizer, the area of ​​the circular electrode can be appropriately reduced, the power consumption of the product can be reduced, and the atomization volume and atomization effects of the product can be improved. The present invention is described above by way of example, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention belong to the scope of protection claimed by the present invention.
