[0017] 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.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustration shows a waterproof safety box for microwave technology, including a box body 1 and a water collection structure 2 inside it. The water collection structure 2 includes a base 201, which extends slopingly from the center to the surrounding area. A pad ring 203 is fixedly connected to the center of the top of the base 201. Water collection troughs 202 are fixedly connected to all four sides of the base 201. Two adjacent water collection troughs 202 are connected. A sliding rod 204 is fixedly connected to the outer wall of the water collection trough 202. A matching sliding groove 206 is opened on the inner wall of the box body 1. A stop bar 205 is fixedly connected to the side of the box body 1 above the sliding groove 206. A tray structure 3 is installed at the center of the inside of the box body 1.

[0019] It is worth noting that the center of the base 1 is raised by the gasket ring 203. When food is heated, liquid spills onto the surface of the base 201 and flows outwards to the water collection tank 202, preventing it from flowing towards the bottom motor 301, thus achieving a waterproof effect. In addition, the edge of the base 201 is designed with a slight tilt angle. This design allows the liquid flowing into the base surface to flow more smoothly into the water collection tank 202, further enhancing the waterproof effect. The inner wall baffle 205 prevents water from seeping into the area below the base 201, guiding the water on the inner wall of the oven 1 into the water collection tank 202 for collection, ensuring the waterproof effect. The water collection tank 202 is installed inside the oven 1, allowing users to intuitively observe the water level every time they use the microwave oven, eliminating the need for additional power supply devices and sensors, thus reducing costs. Even in the event of a power outage, the water level can be clearly seen, ensuring normal use for a long time.

[0020] The chassis 201 is made of quartz glass heat insulation material and the surface is coated with nano-silver technology, which enhances the high temperature resistance of the chassis and effectively avoids the problem of the chassis deforming or being damaged due to high temperature during microwave heating. The nano-silver coating technology not only improves the antibacterial performance of the chassis and ensures the hygiene and safety of food, but also effectively reflects microwaves, improves heating efficiency, and reduces energy waste.

[0021] The cross-section of the stop bar 205 is triangular.

[0022] The triangular cross-section is designed primarily to consider the stability and guiding properties of a triangle. The triangular structure allows it to be more firmly fixed to the inner wall of the chassis 201, preventing it from loosening due to water flow impact. Simultaneously, the apex design of the triangle effectively guides the water flow along a predetermined path into the water collection tank 202, preventing disorderly diffusion of water on the inner wall of the tank 1 and further enhancing the waterproofing effect. Furthermore, the triangular shape increases the contact area between the baffle 205 and the inner wall of the chassis 201, thereby improving the stability and reliability of the fixation.

[0023] See Figure 2 and Figure 3 The tray structure 3 includes a motor 301 and a tray 303. The tray 303 is positioned above the pad ring 203. A support shaft 306 is installed at the bottom of the tray 303. The motor 301 is installed at the center of the bottom inside the housing 1. The support shaft 306 rotates through the chassis 201. The output end of the motor 301 is installed with the through end of the support shaft 306. The motor 301 drives the tray 303 to rotate, ensuring that food can rotate in the microwave oven.

[0024] See Figure 2 and Figure 3 The tray 303 has a countersunk hole 305 at the center of the embedded surface, and the top of the support shaft 306 is connected to an integrally formed threaded sleeve 308, which is equipped with a matching cross screw 304.

[0025] The Phillips head screw 304 passes through the countersunk hole 305 and is tightened to the threaded sleeve 308, thereby firmly fixing the tray 303 and the support shaft 306 together. This ensures that the tray 303 can rotate stably under the drive of the motor 301. This design not only improves the stability of the tray 303, but also makes the disassembly and assembly of the tray 303 more convenient and quick, making it easier for users to clean or replace the tray 303. At the same time, the cooperation between the threaded sleeve 308 and the Phillips head screw 304 also has a certain anti-loosening effect, further enhancing the stability of the tray 303 during use.

[0026] See Figure 2 and Figure 3 The output end of the motor 301 is equipped with a nut 302, and the outer side wall of the bottom end of the support shaft 306 is provided with a matching thread 307.

[0027] Nut 302 is threaded to the bottom end of support shaft 306 for a secure installation. When support shaft 306 passes through chassis 201 and connects to the output end of motor 301, rotating support shaft 306 allows thread 307 to be tightly engaged with nut 302, thus firmly installing support shaft 306 onto motor 301. This design not only ensures the stability of tray 303 during rotation but also simplifies the assembly of tray structure 3, improving the overall reliability and durability. In addition, the threaded connection has a certain self-locking function, which can effectively prevent the tray structure from loosening during use, further enhancing the safety of microwave oven use.
