Description

Technical Field

[0001] This utility model relates to the field of negative oxygen ion generation technology, and in particular to a negative oxygen ion generation device. Background Technology

[0002] A negative ion generator is an electronic device that generates a large number of negative oxygen ions by ionizing air with high voltage. Its core function is to simulate the phenomenon of lightning in nature, converting oxygen molecules in the air into negative oxygen ions. These negative oxygen ions can effectively neutralize and settle positively charged particulate matter such as smoke and pollen in the air, and decompose harmful gases such as formaldehyde, thereby purifying the air and improving indoor environmental quality. Therefore, it is widely integrated into air purifiers, air conditioners, car air purification equipment, and other health-related home appliances.

[0003] Currently, in the production and assembly of existing negative ion generators, the core functional module, namely the device body, is typically installed inside the casing or frame using a relatively traditional fixing method. A common practice is to pre-drill screw holes at corresponding positions on the device body and the outer casing, and then use multiple screws to tighten them, directly or rigidly connecting the device body to the inner wall or bottom plate of the casing. This method relies on the pre-tightening force of the screws for positioning and fixing; its technical principle lies in constructing a static, immovable rigid connection structure to firmly constrain the device body in the predetermined position.

[0004] However, the aforementioned method of rigid connection using screws reveals inherent structural flaws when faced with dynamic forces in actual transportation and usage environments. The core issue is that, as a precision high-voltage electronic device, the negative ion generator experiences slight vibrations in its internal circuitry, particularly in components like the high-voltage transformer, during operation. Furthermore, it inevitably suffers from external bumps and impacts during transportation and handling. These continuous internal and external vibrations act on the fastening screws, easily leading to a decrease in preload and loosening over time. Once the screws loosen, a gap will form between the device body and its outer casing, causing the device body to wobble and shift within the casing, potentially resulting in collisions and abnormal noises between components. More seriously, this unstable displacement alters the safe distance between the internal high-voltage emitter and surrounding components, potentially causing static electricity buildup and high-voltage arcing, severely impacting the device's performance stability and operational safety. Therefore, a negative ion generator is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a negative oxygen ion generating device, aiming to improve the shortcomings of existing screw fixing methods, which are prone to loosening under vibration, leading to shaking and displacement of the device body. This unstable state can change the safety distance of internal high-voltage components, potentially causing risks such as sparking, and seriously affecting the stability and safety of the device performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a negative oxygen ion generating device, including an outer box, a top cover slidably connected to the upper surface of the outer box, a device body disposed inside the outer box, and a positioning component installed inside the outer box;

[0007] The positioning component includes a positioning angle, the lower surface of which is fixedly connected to the bottom wall of the inner cavity of the outer packaging box. A hinge seat is fixedly connected to the bottom wall of the inner cavity of the outer packaging box near the positioning angle. A rotating shaft is fixedly connected inside the hinge seat. An L-shaped positioning plate is rotatably connected to the outer wall of the rotating shaft. Multiple anti-slip strips are fixedly connected to the inner wall of the L-shaped positioning plate. The device body is engaged with the inner wall of the positioning angle. The lower surface of the device body abuts against the upper surface of the L-shaped positioning plate. One side of the outer wall of the anti-slip strip abuts against the outer wall of the device body. A fixing component is installed on the inner side wall of the outer packaging box.

[0011] The inner wall of the fixing box is provided with a second spring, and the outer wall of the card block penetrates through the interior of the outer box and is slidably connected to the inner wall of the positioning hole.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model achieves highly stable fixation of the equipment body by setting up a multi-dimensional positioning and clamping system. The bottom utilizes a positioning angle in conjunction with a rotatable L-shaped positioning plate to initially limit and support the equipment from the bottom and sides. The anti-slip strips on the L-shaped positioning plate further increase friction. The top, through a spring-loaded connecting plate linked to the top cover, applies continuous downward pressure to the equipment body.

The entire process requires no tools, making operation intuitive and quick. Disassembly is also straightforward; simply press the locking blocks manually to unlock and pull open the top cover to easily remove the device. This quick-installation and quick-disassembly structure greatly simplifies the user's operation steps, reduces the difficulty and time cost of installation and maintenance, and improves the user experience and overall efficiency of the product.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5 The present invention provides an embodiment of a negative oxygen ion generating device, comprising an outer casing 1 as an overall protective shell, a top cover 2 for opening and closing slidably connected to the upper surface of the outer casing 1, a device body 3 as a core functional component disposed inside the outer casing 1, and a positioning component for fixing the device body 3 installed inside the outer casing 1.

[0034] The positioning assembly includes a positioning angle 4 for providing reference positioning. The lower surface of the positioning angle 4 is fixedly connected to the bottom wall of the inner cavity of the outer packaging box 1. A hinge seat 5, providing a rotation fulcrum, is fixedly connected to the bottom wall of the inner cavity of the outer packaging box 1 near the positioning angle 4. A rotating shaft 6 is fixedly connected inside the hinge seat 5. An L-shaped positioning plate 7, which provides support and lateral limiting, is rotatably connected to the outer wall of the rotating shaft 6. To increase friction, multiple anti-slip strips 8 are fixedly connected to the inner wall of the L-shaped positioning plate 7. During operation, one corner of the equipment body 3 is engaged with the inner wall of the positioning angle 4, and its lower surface abuts against the upper surface of the L-shaped positioning plate 7. One side of the outer wall of the anti-slip strip 8 abuts against the equipment body 3. To achieve locking, a fixing component is also installed on the inner side wall of the outer packaging box 1. The fixing component includes a fixing box 13 as a mounting base. One side of the outer wall of the fixing box 13 is fixedly connected to the inner side wall of the outer packaging box 1. A sliding plate 14 as a motion carrier is slidably connected to the inner wall of the fixing box 13. A locking block 15 is fixedly connected to one side of the outer wall of the sliding plate 14. Correspondingly, a positioning hole 17 is provided inside the outer packaging box 1 for the locking block 15 to be inserted. To achieve automatic locking, a spring 16 providing elastic force is provided on the inner wall of the fixing box 13. After the locking block 15 passes through the inside of the outer packaging box 1, it is slidably connected to the inner wall of the positioning hole 17.

[0035] Specifically, during installation, first place one corner of the device body 3 close to the positioning angle 4, then rotate the L-shaped positioning plate 7 around the pivot 6 to the working position, so that its horizontal surface supports the bottom of the device body 3, while its vertical surface is pressed against the device body 3 from the side by the anti-slip strip 8, completing the initial fixation of the bottom and sides. Subsequently, when the top cover 2 is closed, the fixing component starts to work. Under the elastic force of the second spring 16, the sliding plate 14 pushes the locking block 15 to automatically slide into and lock into the positioning hole 17, thereby firmly locking the top cover 2. The entire structural design achieves multi-directional limiting of the device body 3, and with the automatic locking function, the installation process requires no tools, is simple and quick to operate, and the fixing effect is firm and reliable.

[0036] Reference Figures 1-5A telescopic rod 9, which serves as a support and guide, is fixedly connected to the lower surface of the inner wall of the top cover 2. A connecting plate 10, which acts as a direct pressing element, is fixedly connected to the lower surface of the telescopic rod 9. To further improve the positioning accuracy, a positioning shaft 11 is also fixedly connected to the lower surface of the connecting plate 10. The outer wall of the positioning shaft 11 can penetrate through a pre-reserved hole inside the equipment body 3. To apply continuous pressing force, a spring 12 is sleeved on the outer wall of the telescopic rod 9. In the closed state, the lower surface of the connecting plate 10 abuts against the upper surface of the equipment body 3. To clarify the installation and force relationship of the spring, one end of the spring 16 is fixedly connected to one side of the inner wall of the fixing box 13, and the other end is fixedly connected to one side of the outer wall of the sliding plate 14 to provide it with pop-out power. The upper end of the spring 12 is fixedly connected to the inner wall of the top cover 2, and the lower end is fixedly connected to the upper surface of the connecting plate 10 to form a complete top-down elastic structure.

[0037] Specifically, when the user closes the top cover 2, the connecting plate 10 fixed below it descends and eventually presses against the upper surface of the device body 3. During this process, the spring 12 sleeved on the telescopic rod 9 is compressed, thereby generating a continuous and stable downward pressure on the connecting plate 10, firmly pressing the device body 3. At the same time, the positioning shaft 11 on the connecting plate 10 is inserted into the hole in the device body 3, providing precise axial and radial positioning of the device body 3 and preventing its horizontal displacement. The elastic characteristics of the spring 12 not only compensate for manufacturing tolerances and ensure the reliability of the clamping force, but also effectively absorb the vibration generated during transportation or use. Working in conjunction with the locking mechanism driven by the previous spring 16, it forms a comprehensive fixing solution that is both stable and reliable and has good shock absorption.

[0038] Working Principle: When using this device, firstly, slide the top cover 2 open and rotate the L-shaped positioning plate 7, which is hinged to the hinge seat 5, outward. Then, place the device body 3 into the outer casing 1, so that one corner of it is engaged with the inner wall of the positioning angle 4. Next, rotate the L-shaped positioning plate 7 back so that its horizontal part abuts against the lower surface of the device body 3, while its vertical anti-slip strip 8 abuts against the outer wall of the device body 3, completing the bottom support and limiting. Then, slide the top cover 2 forward to close it. During this process, the connecting plate 10, which is fixed below the top cover 2, will move downward and abut against the upper surface of the device body 3. The spring 12 on it will be compressed, thereby applying a continuous downward pressure to the device body 3. At the same time, the positioning shaft 11 on the connecting plate 10 will be inserted into the preset hole of the device body 3, playing a role in precise positioning. When the top cover 2 is fully closed, the locking block 15 in the fixing assembly will automatically pop out under the elastic force of the spring 16 and engage in the positioning hole 17, thereby firmly locking the entire device. The entire device securely fixes the main body 3 in the outer box 1 through the coordinated action of multiple points at the bottom, top, and sides.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
