[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a high-protection crucible, including a pot body 1, an outer surface of the pot body 1 is symmetrically provided with an anti-overflow mechanism 3 near the front and rear sides, the anti-overflow mechanism 3 includes an overflow pipe 301, one end of the overflow pipe 301 is fixedly connected to the outer surface of the pot body 1 near the top, the other end of the overflow pipe 301 is provided with a connecting pipe 302, the top of the connecting pipe 302 is fixedly connected to an overflow tank 304, one end of the connecting pipe 302 is rotatably connected to a threaded sleeve 303, the inner surface wall of the threaded sleeve 303 is threadedly connected to the outer surface of the overflow pipe 301, and the pot body 1 is provided with an anti-overflow mechanism 301. A pot cover 11 is placed on the top, and a mounting edge 12 is fixedly connected to the bottom of the pot cover 11 near the edge, and the outer surface of the mounting edge 12 is threadedly connected to the inner surface wall of the pot body 1 near the top, and a handle 2 is fixedly connected to the top center of the pot cover 11, and the outer surface of the pot body 1 near both sides is symmetrically fixedly connected to the exhaust pipe 4, and the outer surface of the exhaust pipe 4 is sleeved with a pressure relief valve 42, and the outer surface of the pressure relief valve 42 is equidistantly provided with a plurality of exhaust holes 44, and the top of one of the pressure relief valves 42 is fixedly connected to a mounting column 5, and the outer surface of the mounting column 5 is threadedly connected to a counterweight 51.
[0023] The effect achieved by the entire embodiment 1 is that the pot body 1 and the pot cover 11 form a crucible as a whole. When the tin powder and other substances are heated, the tin powder substance will be converted from solid to liquid. At this time, the volume will expand, causing the liquid inside the pot body 1 to exceed the safety line. At this time, the liquid will enter the connecting pipe 302 through the overflow pipe 301, and then enter the overflow tank 304 through the connecting pipe 302 for pre-storage. At the same time, the substances inside the pot body 1 will cause the air pressure to increase during the heating reaction process. When the air pressure is too high, the pressure relief valve 42 will be pushed up from the top of the exhaust pipe 4. The gas will then be discharged through the exhaust hole 44 to relieve the air pressure inside the pot body 1. The mutual cooperation effectively avoids the problem of novice operators adding too much material that will expand after melting, causing overflow of high-temperature material or even splashing and injuring people. The protection and safety are improved. By arranging a mounting column 5 on one of the pressure relief valves 42, a counterweight block 51 can be added. The pressure relief valve 42 with a counterweight block 51 can change the pressure relief threshold. The mounting edge 12 is connected to the pot body 1 by a threaded connection, which makes it convenient to fix the pot cover 11 on the top of the pot body 1.
[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a limiting groove 41 is symmetrically provided on the outer surface of the exhaust pipe 4 near the top, a limiting block 43 is symmetrically provided on the inner wall of the pressure relief valve 42 near the bottom, the limiting block 43 is slidably connected to the limiting groove 41, an anti-scalding cover 22 is provided on the outer surface of the handle 2, and an anti-scalding pad 21 is provided on the top of the pot cover 11 below the handle 2.
[0025] The effect achieved by the entire embodiment 2 is that when the air pressure inside the pot body 1 is too high and causes the pressure relief valve 42 to be pushed up to exhaust, the limiting block 43 and the limiting groove 41 cooperate to limit the maximum rising height of the pressure relief valve 42 to avoid separation from the exhaust pipe 4. The handle 2 is provided to facilitate the removal and assembly of the pot cover 11, and the anti-scalding cover 22 is provided to avoid scalding the palm of the hand, and the anti-scalding pad 21 is provided to avoid scalding the back of the hand, thereby achieving the purpose of protection and being safer when used.
[0026] Working principle: when tin powder and other substances are heated, the tin powder substance will be converted from solid to liquid, and the volume will expand at this time, causing the liquid inside the pot body 1 to exceed the safety line. At this time, the liquid will enter the connecting pipe 302 through the overflow pipe 301, and then enter the overflow tank 304 through the connecting pipe 302 for pre-storage. At the same time, the substances inside the pot body 1 will cause the air pressure to increase during the heating reaction process. When the air pressure is too high, the pressure relief valve 42 will be pushed up from the top of the exhaust pipe 4, and then the gas will be discharged through the exhaust hole 44 to relieve the air pressure inside the pot body 1. Under the cooperation of each other, it is effectively avoided that the novice operation adds too much material that will expand after melting, causing the high-temperature material to overflow or even splash and hurt people, and the protection and safety are improved. In addition, the handle 2 is provided to facilitate the removal and disassembly of the pot cover 11, and the anti-scalding cover 22 is provided to avoid scalding the palm of the hand, and the anti-scalding pad 21 is provided to avoid scalding the back of the hand, which achieves the purpose of protection. When used, it is safer.
