[0027] A protection assembly 2 is provided inside the box 101, and the protection assembly 2 includes a partition barrel 201, a square ring plate 202, a water inlet pipe 204, a water outlet pipe 205, and a partition plate 206;

[0028] The partition barrel 201 is sleeved on the outer wall of the inner barrel 102 and fixedly connected to one side of the inner wall of the box body 101. The square ring plate 202 is sleeved on the outer wall of the partition barrel 201 and fixedly connected to the inner wall of the box body 101. The box body 101, the square ring plate 202, the partition barrel 201, and the inner barrel 102 are arranged from outside to inside in sequence. There are gaps between the inner wall of the box body 101 and the outer wall of the square ring plate 202, the inner wall of the square ring plate 202 and the outer wall of the partition barrel 201, and the inner wall of the partition barrel 201 and the outer wall of the inner barrel 102.

[0029] Two water inlet pipes 204 are provided, one water inlet pipe 204 is provided at the bottom of the outer wall of the box body 101 and penetrates inwardly to the inner wall of the partition barrel 201, and the other water inlet pipe 204 is provided at the bottom of the outer wall of the box door 106 and penetrates into the inside of the box door 106;

[0030] There are two water outlet pipes 205, one of which is disposed at the top of the outer wall of the box body 101 and penetrates inwardly to the inner wall of the partition barrel 201, and the other water outlet pipe 205 is disposed at the top of the outer wall of the box door 106 and penetrates into the interior of the box door 106;

[0031] Two partitions 206 are provided, and the two partitions 206 are fixedly connected to the inside of the box door 106 .

[0032] In this embodiment, it is necessary to supplement that: the enclosed space composed of the partition barrel 201 and the square ring plate 202, and the enclosed space composed of the two partitions 206 need to be evacuated to a vacuum state, the enclosed space composed of the square ring plate 202 and the inner wall of the box body 101, and the enclosed space composed of a partition 206 and the inner wall of the box door 106 are filled with sound insulation and heat insulation cotton, and the water inlet pipe 204 and the water outlet pipe 205 need to be connected to an external water pump, etc., to realize the water flow circulation function;

[0033] When using the noise reduction and heat insulation box 1 to reduce noise and insulate the burner, it is necessary to use screws and other tools to first fix the burner to the top of the outer wall of the slide plate 105, then slide the slide plate 105 into the inner barrel 102, and fix the box door 106 to the box body 101 by screws.
