[0024] Reference Figure 1-3 , an embodiment of the present invention provides a microwave device, comprising an outer shell that is easy to move and a heat source installed inside the outer shell, and an air delivery hole 131 is provided at one side end of the outer shell, wherein the air delivery hole 131 injects external air into the interior of the outer shell;

[0025] The outer shell is a hollow box structure;

[0026] The rear end of the outer shell is provided with a plurality of first heat dissipation holes 121, wherein the first heat dissipation holes 121 and the air delivery holes 131 are both provided on the vertical side plate of the outer shell;

[0027] The heat source includes a transformer and a magnetron 4 arranged in layers from bottom to top, wherein the transformer is arranged away from the first heat dissipation hole 121, and the transformer includes at least two first transformers 31 and second transformers 32, and a first fan 21 is arranged between the first transformer 31 and the second transformer 32;

[0028] The magnetron 4 is disposed near the first heat dissipation hole 121, and a second fan 22 is disposed on one side of the magnetron 4; preferably, the air delivery hole 131 is located between the first fan 21 and the second fan 22 in a vertical direction;

[0029] The vertical position of the air delivery hole 131 is located between the first fan 21 and the second fan 22 , and the horizontal position of the air delivery hole 131 is far away from the first heat dissipation hole 121 .

[0030] In this embodiment, the transformer and the magnetron 4 are installed in layers up and down to reduce the mutual influence of the heat generated between them, wherein the transformer is arranged close to the air delivery hole 131, that is, the transformer is arranged away from the first heat dissipation hole 121; wherein the magnetron 4 is arranged close to the first heat dissipation hole 121, and under the action of the first fan 21 and the second fan 22, the heat of the transformer and the magnetron 4 is output to the first heat dissipation hole 121, thereby accelerating the heat dissipation efficiency of the transformer and the magnetron 4; wherein the transformer at the lower end is closer to the air delivery hole 131 than the magnetron 4, because the air delivery hole 131 1 is located between the first fan 21 and the second fan 22 in the vertical direction, so the air entering the outer shell through the air delivery hole 131 flows to both the second fan 22 and the first fan 21, effectively avoiding the mutual influence of the heat generated by the transformer and the magnetron 4; that is, most of the air entering through the air delivery hole 131 contacts the transformer, and part of the air is blown to the magnetron 4 under the extraction of the second fan 22, so in the technical solution, the location of the air delivery hole 131, the location of the transformer and the magnetron play a decisive role in the heat dissipation effect of the technical solution. In this embodiment, the first fan 21 is arranged between the first transformer 31 and the second transformer 32, which can accelerate the flow of hot air between the first transformer 31 and the second transformer 32, and quickly blow the heat generated by the second transformer 32 to the first heat dissipation hole 121; wherein the height of the first transformer 31 is lower than the height of the second transformer 32, wherein the height of the first fan 21 is higher than the height of the second transformer 32, so the first fan 21 fully dissipates the heat of the first transformer 31 and the second transformer 32, and further reduces the heat generated by the first transformer 31 and the second transformer 32 from spreading upward. The outer shell in this embodiment has the function of being easy to move, and preferably a roller is arranged at the bottom end of the outer shell.

[0032] The air duct blown out by the first fan 21 and the air duct blown out by the second fan 22 are isolated from each other to prevent the heat generated by the transformer from acting on the magnetron 4 .

[0033] As a further improved embodiment, the height of the first transformer 31 is lower than the height of the second transformer 32, wherein the height of the first fan 21 is higher than the height of the second transformer 32; this embodiment prevents the first transformer 31 from affecting the air extraction of the first fan 21 due to the height problem, thereby facilitating the flow of hot air around the first transformer 31 and the second transformer 32;

[0034] The first transformer 31 is a columnar structure, and the end face is fixed to the bottom end of the outer shell; the fixed end of the second transformer 32 is a rectangular structure;

[0035] The first transformer 31 includes a power transformer and a magnetron filament transformer, and the second transformer 32 is a magnetron transformer.

[0036] As a further improved embodiment, the first transformer 31 and the second transformer 32 are both arranged close to the gas transmission hole 131, wherein the horizontal position of the first transformer 31 overlaps with the horizontal position of the gas transmission hole 131, and the vertical position of the gas transmission hole 131 is arranged close to the first transformer 31, so as to take away the heat around the first transformer 31; the gas transmission hole 131 is arranged on the gas transmission plate 1311, and the gas transmission plate 1311 and the outer shell are detachably connected or integrally connected;

[0037] The air delivery holes 131 are in the shape of a circle, a rectangle, a waist, a regular polygon, or a rhombus, and the first heat dissipation holes 121 are in the shape of a circle, a rectangle, a regular polygon, a rhombus, or a trapezoid.

[0042] In this embodiment, a mounting module inside the outer shell is formed by setting a first mounting plate 141, an air guide plate 161, and a second mounting plate 162. There are two ways to install the mounting module in this embodiment. One is to first fix the transformer and the magnetron 4 on the mounting module, and then fix the entire mounting module inside the outer shell; the second is to first fix the entire mounting module inside the outer shell, and then fix the transformer and the magnetron 4 on the mounting module. The first mounting method in this embodiment is superior to the second mounting method. The distance from the second fan 22 to the first heat dissipation hole 121 is less than the distance from the first fan 21 to the first heat dissipation hole 121, that is, the distance from the second mounting plate 162 to the front end of the outer shell is less than the length of the second mounting plate 162.
