Description

Technical Field

[0001] This utility model relates to the field of atomizing plate technology, specifically to an atomizing plate with a large atomization volume. Background Technology

[0002] In the field of atomization technology, traditional stainless steel micro-mesh atomizing discs have many limitations. These atomizing discs are typically small in size, such as the common 10mm, 13.8mm, 15mm, 16mm, and 20mm sizes, with corresponding vibration frequencies of 160K, 125K, 110K, 108K, 105K, and 113K, respectively. Taking a 20mm atomizing disc as an example, it generally uses a 16-7.8-0.6 ceramic disc, and its mist output is mainly used in aromatherapy atomization, desktop humidifiers, beauty device atomization, and medical atomizers. However, the atomization effect is often unsatisfactory, characterized by small mist volume and limited atomization amount.

[0003] A deeper analysis reveals several key limitations. First, the small size of the piezoelectric element results in relatively low power and weak vibration, hindering the generation of efficient atomization energy. Second, the limited space available for the small steel sheet within the built-in area of ​​traditional devices directly restricts the usable area for the number of atomizing holes, thus affecting the atomization rate. Furthermore, the low atomization efficiency cannot guarantee a continuous and stable atomization output, making it difficult to meet the demands of industrial applications for high atomization volumes.

[0004] These problems limit the application of traditional micro-mesh atomizing plates in a wider range of fields. Especially in industrial scenarios requiring high atomization output, such as industrial painting, chemical reaction process control, large-scale medical atomization disinfection, and high-volume air humidification, existing technologies often fail to achieve the desired results. The limitations of existing technologies lie in the size and atomization efficiency of the atomizing plates, leading to uneven atomization effects and insufficient atomization volume.

[0005] Therefore, it is necessary to develop a new type of atomizing plate to overcome the shortcomings of existing technologies and provide a solution that can achieve efficient and uniform atomization to meet the urgent needs of atomization technology in industries and medical fields. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model relates to an atomizing plate with a large atomization volume. This structure is simple and reliable, effectively solving the aforementioned technical problems and is suitable for widespread use. To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A high-volume atomizing plate, comprising

[0008] The stainless steel sheet is circular with an outer diameter of 20-22 mm and an atomization zone with an inner diameter of 10-12 mm in the center. The stainless steel sheet has a protrusion at the center of the atomization zone.

[0009] Micropores, a plurality of the micropores being distributed in the atomization zone;

[0010] The piezoelectric ceramic sheet is annular in shape, with an outer diameter of 20-22 mm, an inner diameter of 10-12 mm, and a thickness of 0.5-0.8 mm. It is bonded to the surface of the stainless steel sheet by an epoxy adhesive layer. The electrodes of the piezoelectric ceramic sheet are connected to the wires by soldering, and a sealant layer is also applied to the electrode connection.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the protrusion is hemispherical.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the radius of curvature of the raised hemispherical structure is 5-8mm, and the maximum height of the raised structure is 0.3-0.6mm.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the micropore has a conical hole structure, and the diameter of the inlet end near the liquid side is larger than the diameter of the outlet end near the spray side.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the taper of the conical hole structure is 10° to 30°, and the aperture ratio between the inlet end near the liquid side and the outlet end on the spray side is 2:1.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: a plurality of the micropores are distributed in a concentric circular array, arranged in at least 3 concentric rings from the inside out, and the micropores of the concentric rings are staggered in the radial direction.

[0016] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: by increasing the size of the piezoelectric ceramic sheet, extending its outer diameter to 20 to 22 mm and its inner diameter to 10 to 12 mm, the area of ​​the inner ring atomization zone is increased. In addition, the hemispherical protrusion design in the central area of ​​the atomization sheet can focus energy on the outer ring micropore area, forcing the vibration energy to concentrate towards the center of the atomization zone, avoiding the edge attenuation caused by energy diffusion in the traditional planar structure, and also limiting the parasitic vibration in the non-atomization area, thereby improving the atomization amount. At the same time, the micropore distribution of the stainless steel sheet atomization zone is optimized, and combined with the conical micropore structure, uniform and fine atomized particles are formed, improving the atomization quality.

[0017] This product can significantly increase the atomization volume from around 500ml / h of traditional products to over 2000ml / h, meeting the urgent needs for high atomization volumes in industrial painting, large-scale medical atomization disinfection, and other applications.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0023] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0025] To solve the above technical problems, such as Figure 1-4As shown, this utility model designs an atomizing plate with a large atomization volume, including a stainless steel plate 1 and a piezoelectric ceramic plate 2. The stainless steel plate 1 is circular with an outer diameter of 20-22 mm and an atomizing zone 3 with an inner diameter of 10-12 mm and a thickness of 0.5-0.8 mm in the central area. The piezoelectric ceramic plate 2 is annular with an outer diameter of 20-22 mm, an inner diameter of 10-12 mm, and a thickness of 0.5-0.8 mm. It is bonded to the surface of the stainless steel plate 1 with an epoxy adhesive layer. The electrode of the piezoelectric ceramic plate 2 is connected to a wire by soldering. A sealant is also used. The sealing layer encloses the solder joints and wire connections, forming a waterproof and anti-oxidation barrier, which extends the service life in humid or corrosive environments. The vibration area is increased by more than 56% compared to traditional small-sized piezoelectric sheets (such as 16mm outer diameter). By increasing the volume of the piezoelectric material, the energy conversion power is significantly improved, and the operating frequency is reduced to 80-100kHz. The low-frequency vibration enhances the liquid breaking force, so that the atomization rate jumps from the traditional 500ml / h to more than 2000ml / h. At the same time, the matching design of the large-sized piezoelectric sheet and the atomization area 3 (10-12mm inner diameter) ensures that the vibration energy uniformly covers the micropore area 5.

[0026] The stainless steel sheet 1 has a protrusion 4 at the center of the atomization zone 3. More preferably, the protrusion 4 is hemispherical with a radius of curvature of 5-8 mm and a height of 0.3-0.6 mm. This can focus energy on the outer ring micropore 5 area, forcing the vibration energy to concentrate towards the center of the atomization zone 3. This avoids the edge attenuation caused by energy diffusion in traditional planar structures and also limits the parasitic vibration in the non-atomization zone 3, thereby increasing the atomization amount. During vibration, its curved edge acts as a vibration node, generating high-frequency vertical displacement, which pushes the atomized particles to be sprayed outward at a larger angle. In addition, the introduction of the protrusion 4 structure makes the atomization zone 3 of the stainless steel sheet 1 form a stable mechanical support, making this atomizing sheet particularly suitable for scenarios requiring wide coverage, such as industrial spraying and agricultural greenhouses.

[0027] Micropores 5 are distributed in the atomization zone 3. Preferably, the micropores 5 are conical structures, with the inlet end near the liquid side having a larger diameter than the outlet end near the spray side. The taper of the conical structure is 10° to 30°, and the diameter ratio between the inlet end near the liquid side and the outlet end near the spray side is 2:1. The large inlet diameter reduces liquid flow resistance, while the small outlet diameter enhances droplet breakage, achieving a dual improvement in atomization rate and particle refinement. The inner wall of the conical pore is smooth, and with the periodic scouring effect of vibration energy, the residue of the liquid is reduced, and the clogging rate of the micropores 5 is reduced.

[0028] Based on the above embodiments, this embodiment is further improved, such as... Figure 4As shown, the micropores 5 are arranged in a concentric circular array, with at least three concentric rings arranged from the inside out, and in reality, the number is much greater. The micropores 5 of the concentric rings are staggered in the radial direction. This layout ensures the uniform distribution of liquid on the atomizing plate, avoids uneven atomization in some areas, and makes the atomization effect more uniform and stable, thus improving the atomization quality. The staggered arrangement helps to reduce the accumulation and clogging risk of liquid in the micropores 5, ensuring the long-term stable operation of the atomizing plate.

[0029] It is worth noting that the technical features such as epoxy adhesive layer, solder joint, and electrodes involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0030] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
