Description

Technical Field

[0001] This utility model belongs to the field of microwave heating technology, specifically a cooling self-balancing and leak-proof microwave port structure device. Background Technology

[0002] Microwave heating offers advantages such as rapid heating and strong penetration, generating heat simultaneously at different depths. However, microwave leakage directly impacts the overall heating effect and poses certain safety hazards. Current technologies typically use tin foil wrapped around the microwave-transparent material to prevent leakage, but these methods lack stoppers and are prone to damaging the material when compressed. Furthermore, microwaves generate heat during transmission, damaging both the microwave-transparent material and the sealing material. Summary of the Invention

[0003] The first technical problem that this invention aims to solve is that conventional anti-leakage structures are prone to damaging the wave-transmitting material when compressed.

[0004] The second technical problem that this utility model aims to solve is that conventional anti-leakage structures are easily damaged by the heat generated by microwaves, which can damage the wave-transmitting and sealing materials.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A cooling self-balancing anti-leakage microwave port structure device includes a microwave waveguide, an upper pressure plate, a lower tray, a cavity base plate, a microwave-transparent material, a sealing material, and an annular water channel. The microwave waveguide is fixedly connected to the upper side of the upper pressure plate, and the cavity base plate is fixedly connected to the lower side of the lower tray. The microwave-transparent material is sandwiched between the upper pressure plate and the lower tray. Sealing materials are provided between the microwave-transparent material and the upper pressure plate, and between the microwave-transparent material and the lower tray. An annular water channel is provided in the upper pressure plate, and the annular water channel is located on the outer periphery of the joint between the microwave waveguide and the upper pressure plate.

[0007] Preferably, a groove is provided on the lower side of the upper pressure plate, and a convex stop is provided on the upper side of the lower tray. The outer edge of the convex stop fits with the inner edge of the groove. The wave-transparent material is located in the groove, the sealing material between the wave-transparent material and the upper pressure plate is located at the top of the groove, and the sealing material between the wave-transparent material and the lower tray is located on the top surface of the convex stop.

[0008] Preferably, there is an annular gap between the upper pressure plate and the lower tray, the annular gap being located at the outer periphery of the convex stop.

[0009] Preferably, several protruding ridges are provided on the top wall of the groove and the top surface of the convex stop, and the protruding ridges are in contact with the sealing material.

[0010] Preferably, the upper pressure plate has an upper through hole and the lower tray has a lower through hole, with the axis of the upper through hole and the axis of the lower through hole coinciding with each other.

[0011] In the above technical solutions, the microwave waveguide is a conventional product, essentially a special type of transmission line used in microwave applications. Ordinary waveguides are made of metal tubes (materials include copper and brass, some plated with silver or gold), while newer technologies use electroplated copper-coated ultralight carbon fiber composite materials. In short, in this utility model, the microwave waveguide has a conventional structure and can be implemented according to general technical knowledge in the field. The cavity base plate supports the lower tray. The upper pressure plate and lower tray clamp and fix the wave-transparent material. The sealing material seals between the wave-transparent material and the upper pressure plate, and between the wave-transparent material and the lower tray. Sealing materials can include silicone gaskets, etc.; wave-transparent materials can include glass, ceramics, mica, etc. The annular water channel serves as a cooling water flow channel, providing water cooling and temperature control.

[0012] This invention provides a cooling, self-balancing, leak-proof microwave port structure. The technical solution utilizes an upper pressure plate and a lower tray to clamp and fix the microwave-transparent material, and a sealing structure is provided at the clamping point. Furthermore, a raised stop is provided on the lower tray, forming a mating structure with the groove on the lower side of the upper pressure plate, which helps to seal the microwave overflow channel and also facilitates stable clamping at the clamping position. In addition, this invention provides an annular liquid-cooled water channel on the outer periphery of the joint between the microwave waveguide and the upper pressure plate, which can achieve water-cooling temperature control.
