Description

Technical Field

[0001] The utility model relates to the technical field of preservation technology, and particularly relates to a high-voltage electrostatic field generating device. Background Art

[0002] With the progress of technology and the increasing attention of consumers to the quality, safety and taste of food, food preservation technology is also constantly developing and innovating. Among them, the technology of food preservation by electrostatic generating devices has attracted much attention in recent years. This technology mainly uses the characteristics of the electrostatic field to preserve food, so as to achieve the purpose of extending the shelf life of food, maintaining the original taste and nutritional value of food. The basic principle of electrostatic preservation technology is that a certain intensity of electrostatic field is generated by an electrostatic generating device, and the food is placed in this electrostatic field. In this process, the electrostatic field can affect the water and microorganisms in the food, thereby changing the preservation state of the food. Specifically, the electrostatic field can change the structure and arrangement of water molecules, making them more stable and reducing the water loss rate of the food; at the same time, the electrostatic field can also inhibit microorganisms and reduce their reproduction speed, thereby extending the shelf life of the food. Compared with traditional food preservation methods, electrostatic preservation technology has many advantages. First of all, electrostatic preservation technology does not require the addition of any chemical substances, avoiding the pollution of harmful substances such as preservatives to food, and is safer and healthier. Secondly, this technology is simple to operate and has low energy consumption, which not only reduces the operating costs of enterprises, but also is conducive to environmental protection and energy conservation. Finally, electrostatic preservation technology can significantly improve the preservation effect of food, maintain the original taste and nutritional value of food, and meet the needs of consumers for high-quality food.

[0003] In practical applications, the electrostatic generating device uses a transformer to boost the AC voltage of 220V to an AC voltage of 800 - 3000V, and after passing through the output controller, it reaches the discharge source. The existing electrostatic preservation refrigerator uses a transformer to boost the AC voltage of 220V to an AC voltage of 800 - 3000V. The input voltage is relatively large, and it is easy to cause electric shock accidents. Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0004] The invention purpose of the utility model is to solve the problem of low safety when the existing electrostatic generating device is applied to the preservation technology, and provide a high-voltage electrostatic field generating device.

[0005] To achieve the above invention purpose, the utility model adopts the following technical solutions:

[0006] High-voltage electrostatic field generating device, comprising an outer box body, an inner box body and an electrostatic generating module. The electrostatic generating module is arranged in the inner box body and includes a voltage transformation module. The inner box body is arranged in the outer box body. The outer box body is also provided with an input interface module and an output interface module. The input interface module is connected to the low-voltage input end of the voltage transformation module, and the output interface module is connected to the high-voltage output end of the voltage transformation module.

[0007] Compared with the prior art, the high-voltage electrostatic generating device of the present utility model has a double-layer structure design composed of an outer box body and an inner box body. Such a design can effectively isolate the electrostatic generating module from the outside world, reducing the risk of accidental touch or damage to the core components. At the same time, the double box body also provides additional electrical insulation and mechanical protection, increasing the safety of the entire system. In addition, the input interface module and the output interface module are respectively connected to the low-voltage input module and the high-voltage output module. Such a design not only facilitates the access of external devices, but also provides additional electrical isolation through the interface module, further enhancing the safety of the system.

[0008] Furthermore, the outer box body is also provided with a switch module penetrating its side wall, and the input interface module is arranged on the switch module. In this solution, the input interface module and the switch module are of an integrated structure.

[0009] Furthermore, the outer box body includes a front side plate, a rear side plate, a left side plate, a right side plate, an upper side plate and a lower side plate. The inner box body is installed in the middle of the rear side plate and has a preset distance from the upper, lower, left, right and front ends of the outer box body. Through holes for wires are provided on opposite sides of the front end face thereof. This solution further enhances the safety of the device by arranging the inner box body in the middle of the rear side plate of the outer shell and setting a preset distance from the end of the outer box body. Even in extreme cases, if there is a problem with the electrostatic generating module in the inner box body, the presence of the outer box body can provide an additional layer of protection, reducing the potential threat to the operator. At the same time, a certain preset distance is maintained between the inner box body and the outer box body. Such a design is conducive to air circulation and improves the heat dissipation performance of the device. The electrostatic generating module may generate heat during operation. A good heat dissipation design can extend the service life of the device and ensure its stable operation.

[0010] Furthermore, the input interface module and the output interface module are arranged on the same side of the outer box body.

[0011] Furthermore, it also includes a first anti-interference element and a second anti-interference element. The first anti-interference element is arranged between the input interface module and the low-voltage input end; the second anti-interference element is arranged between the output interface module and the high-voltage output end. By adding anti-interference elements in this solution, not only the anti-interference ability and signal quality of the high-voltage electrostatic generating device are enhanced, but also the safety, maintainability and cost-effectiveness of the system are improved.

[0012] Furthermore, both the first anti-interference element and the second anti-interference element are magnetic rings. The magnetic rings are located in the outer box body. The first anti-interference element is threaded through the connecting wire of the low-voltage input end, and the second anti-interference element is threaded through the connecting wire of the high-voltage output end. In this solution, the magnetic rings have standardized interfaces and dimensions, which makes it convenient to replace or add new anti-interference elements during future maintenance and upgrades to adapt to the changing working environment or improve the performance of the system. At the same time, the magnetic rings being placed in the outer box body not only facilitates the replacement operation of the components but also effectively isolates them from the electrostatic generating device, thereby enhancing the safety and stability of the entire system.

[0013] Furthermore, the electrostatic generating module further includes a current-limiting module. The negative connection end of the high-voltage output end is electrically connected to the positive connection end of the low-voltage input end, and the current-limiting module is connected in series between the negative connection end of the high-voltage output end and the positive connection end of the low-voltage input end; the positive connection end of the high-voltage output end is electrically connected to the output interface module. In this solution, by introducing the current-limiting module, the magnitude of the current flowing through the high-voltage output end of the high-voltage electrostatic generating device can be effectively limited. When the output voltage is very high, the output current decreases. This design significantly improves the safety of the device.

[0014] Furthermore, it further includes several groups of high-voltage output branches. The output interface module includes output interfaces equal in number to the high-voltage output branches. The current input ends of several groups of high-voltage output branches are connected in parallel to the positive connection end of the high-voltage output end.
