Description

Technical Field

[0001] This utility model relates to the technical field of atomizers, and in particular to an atomizing plate assembly with an elastic conductive structure. Background Technology

[0002] In nebulizers, humidifiers, and other nebulization devices, the atomizing plate is a core component, and the stability and reliability of its electrode connections directly affect the device's efficiency and lifespan. Currently, traditional atomizing plates often use soldered leads or mechanical crimping to achieve circuit conduction; however, these connection methods have many technical drawbacks in practical applications.

[0003] When using welding for connection, the high-temperature welding process can easily cause thermal stress damage to the atomizing plate body (especially atomizing plates made of brittle materials such as piezoelectric ceramics). This not only reduces the product yield and increases production costs, but also, during the welding operation, improper handling during the connection of the welding wire and electrode post can easily damage the lower housing of the equipment, further affecting the assembly quality. At the same time, welding connections make the disassembly and maintenance of the atomizing plate extremely inconvenient. Once a malfunction occurs, complex desoldering and resoldering operations are often required by professionals, significantly reducing the maintainability of the equipment.

[0004] When mechanical crimping is used, due to the lack of an effective pressure compensation mechanism, the crimped parts are prone to loosening due to vibration, wear and aging of materials during use. This leads to increased contact resistance, affects the stability of conductivity, and may even cause electric arcing, exacerbating electrode wear and shortening the service life of the atomizing plate.

[0005] To address the problems of high risk of thermal damage, difficult assembly, inconvenient maintenance, and short service life of existing atomizing plate electrode connection methods, this utility model proposes an atomizing plate assembly with an elastic conductive structure. Through an innovative method of conducting electricity via spring contact, it aims to overcome the above-mentioned technical defects and improve the overall performance and reliability of atomizing equipment. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an atomizing plate assembly with an elastic conductive structure that is easy to assemble and maintain, reliable in use, and has a low failure rate.

[0007] This utility model discloses an atomizing plate assembly with an elastic conductive structure, comprising an upper shell and a lower shell, which are snap-fitted together. An atomizing plate is disposed between the upper shell and the lower shell, and sealing rings are provided between the atomizing plate and both the upper and lower shells. Two sets of electrode posts are disposed at the bottom of the lower shell. The top conductive parts of the two sets of electrode posts extend into the lower shell. A voltage-conducting sheet is disposed at the edge of the atomizing plate. The two sets of voltage-conducting sheets correspond to the positions of the two sets of electrode posts, and an elastic conductive component is disposed between the two sets of voltage-conducting sheets and the two sets of electrode posts. A first limiting structure is provided between the electrode post and the corresponding elastic conductive component, and a second limiting structure is provided between the voltage-conducting sheet and the corresponding elastic conductive component.

[0008] Furthermore, the elastic conductive component is configured as a helical spring or a helical sheet.

[0009] Furthermore, the first limiting structure is configured as a limiting ring, which is installed at one end of the electrode post located inside the lower housing, and one end of the elastic conductive component is located inside the limiting ring, with the elastic conductive component pressed tightly against the electrode post.

[0010] Furthermore, the second limiting structure is configured as a hemispherical protrusion, the elastic conductive component is pressed tightly against the corresponding voltage conductive sheet, and the hemispherical protrusion is located in the elastic conductive component mounting position.

[0011] Furthermore, the helical spring or helical sheet is made of a corrosion-resistant alloy material or has a gold-plated surface.

[0012] Furthermore, the contact pressure between the elastic conductive component and the corresponding electrode post or voltage-conducting sheet is ≥0.5N.

[0013] Furthermore, the contact resistance between the elastic conductive component and the corresponding electrode post or voltage-conducting sheet is ≤0.1Ω.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Improved ease of assembly and maintenance: The use of flexible conductive components enables weld-free connections, greatly simplifying the assembly and disassembly process, reducing assembly difficulty and maintenance costs. Non-professionals can easily operate the equipment, significantly improving production efficiency and ease of subsequent maintenance.

[0016] 2. Enhanced conductivity stability: The contact pressure between the elastic conductive component and the electrode post and voltage-conducting sheet is ≥0.5N, and the contact resistance is ≤0.1Ω. It can always maintain stable surface contact, effectively avoiding the conductivity instability problem caused by loosening in traditional connection methods, and ensuring continuous and reliable current transmission.

[0017] 3. More stable structural connection: The first limiting structure restricts the radial displacement of the elastic conductive component and the electrode post, and the second limiting structure prevents the elastic conductive component from sliding relative to the conductive sheet. The double limiting prevents the component from shifting or falling off during installation and use, further improving the conductivity reliability.

[0018] 4. Significantly extended service life: The elastic conductive components are made of corrosion-resistant alloy materials or have gold-plated surfaces, which have excellent anti-oxidation and corrosion resistance, reducing arc loss and significantly extending the service life of the components; at the same time, the sealing rings prevent moisture intrusion, enhancing the overall sealing and durability.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 4As shown, this utility model discloses an atomizing plate 3 assembly with an elastic conductive structure, comprising an upper housing 1 and a lower housing 2, which are snap-fitted together. An atomizing plate 3 is disposed between the upper housing 1 and the lower housing 2, and sealing rings 4 are provided between the atomizing plate 3 and both the upper housing 1 and the lower housing 2. Two sets of electrode posts 5 are disposed at the bottom of the lower housing 2. The atomizing plate 3 has conductive portions at its top extending into the lower housing 2. Voltage-conducting plates 6 are disposed at the edges of the atomizing plate 3, and the positions of the two sets of voltage-conducting plates 6 correspond to the positions of the two sets of electrode posts 5, with an elastic conductive layer between the two sets of voltage-conducting plates 6 and the two sets of electrode posts 5. The electrical component 7 has a first limiting structure between the electrode post 5 and the corresponding elastic conductive component 7, and a second limiting structure between the voltage conductive sheet 6 and the corresponding elastic conductive component 7. The elastic conductive component 7 is configured as a helical spring or a helical sheet. The first limiting structure is configured as a limiting ring 8, which is installed at one end of the electrode post 5 located inside the lower housing 2. One end of the elastic conductive component 7 is located inside the limiting ring 8, and the elastic conductive component 7 is pressed tightly against the electrode post 5. The second limiting structure is configured as a hemispherical protrusion 9, which is pressed tightly against the elastic conductive component 7 and the corresponding voltage conductive sheet 6, and the hemispherical protrusion 9 is located in the locking position of the elastic conductive component 7.

[0026] Upper housing 1 and lower housing 2 are snap-fitted together: The upper housing 1 and lower housing 2 are connected by a snap-fit ​​structure. This connection method is simple to operate and facilitates quick assembly. Compared with traditional welding or complex connection methods, it not only saves assembly time but also facilitates subsequent disassembly and maintenance, improving production efficiency and ease of maintenance.

[0027] An atomizing plate 3 is disposed between the upper housing 1 and the lower housing 2, and sealing rings 4 are disposed between the atomizing plate 3 and both the upper housing 1 and the lower housing 2. During assembly, the sealing rings 4 are first placed at the contact positions between the upper housing 1 and the lower housing 2 and the atomizing plate 3, and then the atomizing plate 3 is installed between the upper and lower housings 2. The sealing rings 4 can effectively prevent external substances such as moisture from entering the component, avoiding corrosion of internal components and ensuring the insulation performance and service life of the component. At the same time, the sealing rings 4 can also provide a certain buffering effect for the atomizing plate 3, reducing impact damage to the atomizing plate 3 during assembly and use.

[0028] Two sets of electrode posts 5 are provided at the bottom of the lower housing 2, with the conductive parts at the top of both sets of electrode posts 5 extending into the interior of the lower housing 2. During the fabrication of the lower housing 2, the two sets of electrode posts 5 are installed at their designed positions at the bottom, ensuring that the conductive parts at the top of the electrode posts 5 smoothly extend into the interior of the lower housing 2. This structural design provides a basis for the connection between the electrode posts 5 and the internal elastic conductive component 7, ensuring smooth current transmission. Furthermore, the precise positioning of the electrode posts 5 facilitates integration with other components.

[0029] A voltage-conducting plate 6 is provided at the edge of the atomizing plate 3. Two sets of voltage-conducting plates 6 correspond to the positions of two sets of electrode posts 5, and an elastic conductive component 7 is provided between the two sets of voltage-conducting plates 6 and the two sets of electrode posts 5. The voltage-conducting plates 6 are installed at specific positions on the edge of the atomizing plate 3, corresponding one-to-one with the positions of the electrode posts 5. Then, the elastic conductive component 7 is installed between the voltage-conducting plates 6 and the electrode posts 5. The elastic conductive component 7 uses a helical spring or helical sheet. This structure utilizes its own elasticity to generate pressure, ensuring close contact with the voltage-conducting plates 6 and the electrode posts 5, achieving good conductivity. Simultaneously, the elastic characteristics can adaptively compensate for wear, ensuring long-term stable conductivity.

[0030] A first limiting structure, namely a limiting ring 8, is provided between the electrode post 5 and the corresponding elastic conductive component 7. The limiting ring 8 is installed at one end of the electrode post 5 located inside the lower housing 2, and one end of the elastic conductive component 7 is located inside the limiting ring 8, with the elastic conductive component 7 pressed tightly against the electrode post 5. The limiting ring 8 is fixedly installed at one end of the electrode post 5 located inside the lower housing 2, and then one end of the elastic conductive component 7 is placed into the limiting ring 8, so that the elastic conductive component 7 is pressed tightly against the electrode post 5. The limiting ring 8 can effectively limit the radial displacement of the elastic conductive component 7, prevent it from falling off the electrode post 5, ensure the stability of the connection between the elastic conductive component 7 and the electrode post 5, and ensure that the current transmission is not affected.

[0031] A second limiting structure, namely a hemispherical protrusion 9, is provided between the voltage-conducting sheet 6 and the corresponding elastic conductive component 7. The elastic conductive component 7 and the corresponding voltage-conducting sheet 6 are pressed tightly together, and the hemispherical protrusion 9 is positioned to hold the elastic conductive component 7 in place. The hemispherical protrusion 9 on the voltage-conducting sheet 6 presses the elastic conductive component 7 tightly against the voltage-conducting sheet 6, thus securing the hemispherical protrusion 9 onto the elastic conductive component 7. The hemispherical protrusion 9 limits the elastic conductive component 7, preventing it from sliding during contact with the voltage-conducting sheet 6. Especially during assembly or use, if bumps or impacts occur, it ensures that the elastic conductive component 7 will not slip off the voltage-conducting sheet 6, further ensuring the stability and reliability of the contact between the two and reducing the probability of poor contact.

[0032] As a preferred embodiment of the above, the helical spring or helical sheet is made of a corrosion-resistant alloy material or has a gold-plated surface.

[0033] The helical spring or helical spring sheet is made of corrosion-resistant alloy material or gold-plated surface: The helical spring or helical spring sheet is made of corrosion-resistant alloy material or gold-plated surface as elastic conductive component 7. This material selection can effectively improve the component's oxidation resistance and corrosion resistance, reduce arc loss during use, greatly extend the component's service life, and enable it to work stably in humid and corrosive environments.

[0034] As a preferred embodiment of the above embodiment, the contact pressure between the elastic conductive component 7 and the corresponding electrode post 5 or voltage conductive sheet 6 is ≥0.5N;

[0035] The contact pressure between the elastic conductive component 7 and the corresponding electrode post 5 or voltage conductive sheet 6 is ≥0.5N: Through the structural design and material selection of the elastic conductive component 7, it is ensured that the contact pressure between it and the electrode post 5 or voltage conductive sheet 6 is ≥0.5N. Sufficient contact pressure can ensure that a stable surface contact is formed between the two, reduce contact resistance, make the conductivity more stable and reliable, and avoid poor conductivity problems caused by insufficient contact pressure.

[0036] As a preferred embodiment of the above embodiment, the contact resistance between the elastic conductive component 7 and the corresponding electrode post 5 or voltage conductive sheet 6 is ≤0.1Ω;

[0037] The contact resistance between the elastic conductive component 7 and the corresponding electrode post 5 or voltage conductive sheet 6 is ≤0.1Ω: Due to the good contact and appropriate contact pressure between the elastic conductive component 7 and the electrode post 5 or voltage conductive sheet 6, the contact resistance is ≤0.1Ω. Low contact resistance reduces losses during current transmission, improves energy utilization, ensures that the atomizing plate 3 can work normally and efficiently, and enhances the performance of the entire atomizing device.

[0038] The working principle of this utility model is as follows:

[0039] When the atomizing plate 3 assembly with an elastic conductive structure is in operation, current is input from the electrode post 5 at the bottom of the lower housing 2. Through the close contact between the electrode post 5 and the elastic conductive component 7, the current is conducted to the elastic conductive component 7. Since the elastic conductive component 7 also maintains a stable and close contact with the voltage-conducting sheet 6 at the edge of the atomizing plate 3, the current is further transmitted to the voltage-conducting sheet 6, thereby enabling the atomizing plate 3 to obtain electrical energy.

[0040] Throughout the current transmission process, the elastic conductive component 7, thanks to its own elasticity, maintains a contact pressure ≥0.5N with the electrode post 5 and the voltage conductive sheet 6, ensuring a contact resistance ≤0.1Ω and guaranteeing stable current transmission. Simultaneously, the first and second limiting structures prevent displacement or detachment of the elastic conductive component 7 from the electrode post 5 and the voltage conductive sheet 6, respectively, further ensuring the reliability of conductivity.

[0041] The sealing ring 4 effectively prevents external moisture and other contaminants from entering the component, protecting all parts from corrosion. The corrosion-resistant design of the elastic conductive component 7 reduces arc loss, extends the component's lifespan, and enables the entire atomizing plate 3 assembly to operate stably and efficiently, providing reliable atomization functionality for medical nebulizers, humidifiers, and other devices.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
