The latch 72 will be inserted into the limit hole 74 with the help of the contraction force of the spring 77. The spring 77 improves the stability of the latch 72 inserted into the limit hole 74 and prevents the latch 72 from falling out of the limit hole 74 due to shaking. The surface of the kettle body 1 is fixedly connected to two bottom plates 78, and the vertical section of the bottom plate 78 is "L" shaped. When the heat preservation cover 75 is placed on the surface of the bottom plate 78, the heat preservation cover 75 will slide along the surface of the bottom plate 78 when it moves, and the bottom plate 78 can support the protective cover, thereby further facilitating the installation of the heat preservation cotton 76 on the outer surface of the kettle body 1. The two heat preservation covers 75 are fixedly connected to the side close to each other with a sealing strip 79, and the sealing strip 79 is made of rubber. When the heat preservation cotton 76 is tightly attached to the surface of the kettle body 1, the sealing strips 79 on the surface of the two protective covers will be tightly attached together, and the sealing strip 79 can improve the tightness of the fit of the two protective covers, and further reduce the loss of heat energy.

[0032] Reference Figure 2 and Figure 5As shown, specifically, the filtering structure 8 includes a round rod 81, which is fixedly connected to the surface of the kettle body 1, and a filter box 82 is fixedly connected to the arc surface of the round rod 81, and a filter plate 83 is fixedly connected to the surface of the filter box 82.

When the latch 72 moves to a suitable position, the spring 77 is in a stretched state, and then the heat-insulating cover 75 is pushed, and the movement of the heat-insulating cover 75 drives the heat-insulating cotton 76 to move in the direction close to the kettle body 1, and the heat-insulating cover 75 moves. The cover 75 moves and slides along the surface of the bottom plate 78, and the bottom plate 78 plays the role of supporting the protective cover, thereby further facilitating the installation of the thermal insulation cotton 76 on the outer surface of the kettle body 1. When the thermal insulation cotton 76 is tightly attached to the surface of the kettle body 1, the sealing strips 79 on the surfaces of the two protective covers will fit tightly together. At this time, the limit arm 73 will be inserted into the bracket 71, and then the pin 72 will be released. The pin 72 will be inserted into the limit hole 74 with the help of the contraction force of the spring 77, and the pin 72 will reach the position of limiting the limit arm 73, thereby limiting the position of the thermal insulation cotton 76.

[0034] When the filter plate 83 needs to be cleaned, first pull the limit rod 86, the limit rod 86 moves in the fixed plate 85, the limit rod 86 will gradually come out of the round hole 87 when moving, the limit rod 86 will pull the rope 88 when moving, when the limit rod 86 comes out of the round hole 87, turn the turntable 89, the turntable 89 will drive the round rod 81 to rotate, the round rod 81 will drive the filter box 82 to rotate, the filter box 82 will gradually come out of the circular groove 84 when rotating, when the filter box 82 rotates to a suitable angle, press the limit rod 86, the limit rod 86 will be inserted into the round hole 87, the limit rod 86 When the position of the limiting round rod 81 is reached, the position of the filter box 82 is further limited. At this time, the filter plate 83 will be located outside the circular groove 84, so that it is convenient to clean the filter plate 83. After the filter plate 83 is cleaned, the limiting rod 86 is pulled out from the circular hole 87, and then the turntable 89 is rotated in the opposite direction. The round rod 81 will drive the filter box 82 to reset with the help of the rotating force of the turntable 89. When the filter box 82 is reset, the limiting rod 86 is inserted into the circular hole 87 to limit the position of the filter box 82. At this time, when sodium hydrosulfide is added into the kettle body 1 through the feeding pipe 3, the filter plate 83 will filter the sodium hydrosulfide.
