Description

Technical Field

[0001] The present invention belongs to the technical field of piezoelectric ceramic atomizing sheets, and in particular relates to a piezoelectric ceramic atomizing sheet. Background Art

[0002] The piezoelectric ceramic atomizer uses a certain stable voltage to oscillate the frequency. Depending on the thickness of the product, the oscillation frequency is basically controlled between 1.53 and 3.0 MHZ, which has exceeded the hearing range of the human ear. This oscillation frequency does not cause any harm to humans or animals. When the piezoelectric ceramic atomizer is working, the liquid water molecule structure is thrown up and broken up to produce a natural and elegant water mist, and it can be achieved without heating or adding any chemical reagents. In the prior art, piezoelectric ceramic atomizers are mainly used in indoor humidification, indoor aromatherapy, dust removal and other fields, requiring the product to have small atomized particles and large atomization volume. However, since the load formed during welding will oppress the oscillation of the atomizer, the larger the solder joint, the more serious the impact, which makes the oscillation of the atomizer more restrained, greatly affecting the atomization volume and atomization effect of the product, and often there will be low water cut-off sensitivity, small atomization volume, unstable atomization process and other phenomena.

[0003] Therefore, whether it is possible to invent a piezoelectric ceramic atomizer to overcome the above-mentioned defects is a technical problem to be solved by those skilled in the art. Summary of the invention

[0004] The present invention aims to provide a piezoelectric ceramic atomizer, which can effectively improve the oscillation effect of the piezoelectric ceramic by designing a welding area on the inclined surface of the truncated cone of the piezoelectric ceramic and controlling the size of the truncated cone of the piezoelectric ceramic through a unique shape and structural design. The oscillation of the product itself is not restrained or oppressed, so that the atomization effect of the product is fully reflected, and a good energy-gathering effect can be achieved, thereby improving the atomization amount and stability of the product. In addition, by designing the welding surface on the inclined surface of the truncated cone, it can effectively prevent employees from diffusing solder onto the electrode surface during welding.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A piezoelectric ceramic atomizing sheet, comprising a piezoelectric ceramic sheet with a truncated cone-shaped upper portion and a cylindrical lower portion, a front circular electrode being arranged on the bottom surface of the piezoelectric ceramic sheet, a reverse circular electrode and a reverse electrode connecting wire being arranged on the top surface, a reverse electrode welding area and a reverse welding area being arranged on the inclined surface of the truncated cone, and a side connecting wire being arranged on the side surface of the cylinder;

[0007] The back electrode welding area is connected to the back circular electrode through the back electrode connecting line to form conduction; the back welding area is connected to the front circular electrode through the side connecting line to form conduction.

[0008] Preferably, the top surface and the bottom surface of the piezoelectric ceramic sheet are parallel to each other and have smooth surfaces.

[0009] Preferably, the piezoelectric ceramic sheet has a thickness of 0.5 to 3.0 mm and a bottom diameter of 10 to 35 mm.

[0010] Preferably, the diameter of the front circular electrode is larger than the top surface diameter of the piezoelectric ceramic sheet.

[0011] Preferably, the centers of the front circular electrode and the back circular electrode are on the same vertical line.

[0012] Preferably, the reverse electrode welding area and the reverse welding area do not overlap with each other.

[0013] Preferably, the diameter of the reverse circular electrode is smaller than or equal to the top surface diameter of the piezoelectric ceramic sheet, or can cover the truncated cone slope of the piezoelectric ceramic sheet.

[0014] Preferably, the front circular electrode is further coated with a protective layer, and the diameter of the protective layer is smaller than the diameter of the front circular electrode.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Effectively prevent solder from diffusing onto the electrode surface during welding;

[0017] 2. Solve the problem of small atomization volume;

[0018] 3. The atomizer is not pressed by the welding point, and the oscillation effect is more obvious.

[0019] 4. Improve the concentration of atomization and achieve good energy-gathering effect;

[0020] 5. Improve the water-off sensitivity of the product to avoid dry burning. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below in conjunction with the accompanying drawings and examples:

[0025] An embodiment of the present invention is Figure 1 , Figure 2 , Figure 3 As shown, it includes a piezoelectric ceramic sheet 1, the upper part of the piezoelectric ceramic sheet 1 is in the shape of a truncated cone and the lower part is in the shape of a cylinder, the side of the truncated cone facing upward is the top surface of the piezoelectric ceramic sheet 1, and the side of the cylinder facing downward is the bottom surface, and a front circular electrode 2 is provided on the bottom surface of the piezoelectric ceramic sheet 1; a back circular electrode 5 and a back electrode connecting wire 6 are provided on the top surface of the piezoelectric ceramic sheet 1; a back electrode welding area 7 and a back welding area 8 are provided on the truncated cone inclined surface of the piezoelectric ceramic sheet 1, and a side connecting wire 4 is provided on the side surface of the cylinder of the piezoelectric ceramic sheet 1; the back electrode welding area 7 is connected to the back circular electrode 5 through the back electrode connecting wire 6 to form conduction; the back welding area 8 is connected to the front circular electrode 2 through the side connecting wire 4 to form conduction. Since the back electrode welding area 7 and the back welding area 8 are designed on the truncated cone inclined surface of the piezoelectric ceramic sheet 1, it can effectively prevent the solder from diffusing onto the back circular electrode 5. At the same time, the positive pressure on the piezoelectric ceramic sheet 1 caused by the load formed during welding is reduced, which greatly reduces the loss of product vibration.

[0026] Specifically, the top and bottom surfaces of the piezoelectric ceramic sheet 1 are parallel to each other and have smooth surfaces. The overall thickness of the piezoelectric ceramic sheet 1 is 0.5 to 3.0 mm, and the bottom diameter is 10 to 35 mm. By controlling the size of the truncated cone of the piezoelectric ceramic sheet 1, the oscillation effect of the piezoelectric ceramic sheet can be effectively improved. The oscillation of the piezoelectric ceramic sheet 1 itself is not restrained or oppressed, so that the atomization effect of the product is fully reflected, and a good energy-gathering effect can be achieved, thereby improving the atomization amount and stability of the product.

[0027] Specifically, the diameter of the front circular electrode 2 is greater than the top surface diameter of the piezoelectric ceramic sheet 1 , and the centers of the front circular electrode 2 and the back circular electrode 5 are on the same vertical line.

[0028] Specifically, the reverse electrode welding area 7 and the reverse welding area 8 do not overlap each other. The pressure direction formed by the welding area is inconsistent with the oscillation direction of the electrode, which is significantly different from the previous welding area and the electrode area being on the same horizontal plane. This can effectively avoid the direct influence of the welding area on the electrode oscillation, so that the atomization effect is not lost or restrained, and at the same time, it can prevent the solder from diffusing to the surface of the circular electrode.

[0029] Specifically, the diameter of the reverse circular electrode 5 is preferably smaller than or equal to the top surface diameter of the piezoelectric ceramic sheet 1 , but may also cover the truncated cone slope of the piezoelectric ceramic sheet 1 .

[0030] Specifically, a protective layer 3 is also coated on the front circular electrode 2, and the diameter of the protective layer 3 is smaller than the diameter of the front circular electrode 2. By coating the protective layer 3, the corrosion of the front circular electrode 2 caused by direct contact of the liquid can be effectively avoided, thereby delaying the service life of the piezoelectric ceramic atomizer. More specifically, the protective layer 3 can be made of glass glaze or other corrosion-resistant materials, which are not specifically limited here.

[0031] 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.
