Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-Figure 5 A shell structure of an electroacoustic alarm controller terminal includes a lower shell 1. The outer portion of the lower shell 1 is provided with an upper shell 2 slidably connected thereto. Four rubber support blocks 3 are fixed to the bottom of the lower shell 1. The four rubber support blocks 3 are distributed in a rectangular shape and can support the lower shell 1 to ensure its stability when placed on a desktop, while facilitating heat dissipation by a radiator 17.

[0030] A locking rod 9 fixedly connected to the slider 7 is penetrated by the locking rod 9, which penetrates the upper shell 2 and is slidably connected to it. A strip groove 10 is penetrated by the lower shell 1, and the locking rod 9 is slidably connected in the strip groove 10. A sleeve 12 is fixedly connected to the inner bottom of the strip groove 10, and a short rod 13 is slidably connected in the sleeve 12. A buffer block 11 is fixed to the upper end of the short rod 13, and the buffer block 11 slides against the inner wall of the strip groove 10. A first spring 14 is fixed to the bottom of the buffer block 11, and the bottom of the first spring 14 is fixedly connected to the inner bottom of the strip groove 10. The first spring 14 is sleeved on the outside of the sleeve 12 and the short rod 13, and the locking rod 9 is against the upper end of the buffer block 11.

[0031] Through the above, the upper shell 2 and the lower shell 1 can be connected together. When an object falls on the upper shell 2, the upper shell 2 will be driven to move downward. The downward movement of the upper shell 2 drives the locking rod 9 downward. The downward movement of the locking rod 9 squeezes the buffer block 11 downward, thereby causing relative movement between the short rod 13 and the sleeve 12. At this time, the first spring 14 is compressed, which can provide buffering protection for the upper shell 2 and reduce damage to the upper shell 2.

[0032] When the upper shell 2 needs to be removed, the staff manually pulls the pull block 6 to drive the locking rod 9 to move, so that the locking rod 9 is disengaged from the strip groove 10. At this time, the upper shell 2 is no longer restricted and can be removed. The operation is simple and convenient.

[0034] In this embodiment, a bracket mechanism is also included; the bracket mechanism includes four support rods 19 fixed to the bottom of the lower shell 1, and a heat-conducting rubber plate 20 is fixed to the upper ends of the four support rods 19.

[0035] In this embodiment, a heat exchange mechanism is also included; the heat exchange mechanism includes a water tank 25 installed at the bottom of the lower shell 1, a water pump 22 is installed on the water tank 25, a water inlet pipe 24 is installed at the water inlet end of the water pump 22, the water inlet pipe 24 is connected to the water tank 25, a water outlet pipe 23 is installed at the water outlet end of the water pump 22, a serpentine heat exchange channel is provided in the heat conductive rubber plate 20, the water outlet pipe 23 is fixedly connected to the heat conductive rubber plate 20 and communicated with one end of the serpentine heat exchange channel, and the heat conductive rubber plate 20 is installed There is a return pipe 21 connected to the serpentine heat exchange channel, and the other end of the return pipe 21 is connected to the water tank 25; the water pump 22 can transport the clean water in the water tank 25 to the serpentine heat exchange channel through the water inlet pipe 24 and the water outlet pipe 23, and then flow into the water tank 25 through the return pipe 21, so as to realize the circulation of clean water; the clean water flows in the serpentine heat exchange channel, which can exchange heat with the heat-conducting rubber plate 20, and then realize heat exchange with the circuit board, and realize cooling of the circuit board.

[0036] In this embodiment, a refrigeration mechanism is also included, which includes a through groove 15 that runs through the lower shell body 1, a semiconductor refrigeration plate 16 is fixed to the bottom of the water tank 25, the cooling end of the semiconductor refrigeration plate 16 is against the water tank 25, the semiconductor refrigeration plate 16 is set through the through groove 15, and a radiator 17 is installed at the heating end of the semiconductor refrigeration plate 16; since the temperature of the clean water is increased due to heat exchange, the heat exchange effect on the heat-conducting rubber plate 20 is reduced, for this reason, the semiconductor refrigeration plate 16 can cool the flowing clean water, so that the temperature of the clean water can be reduced, so that the low-temperature clean water can more effectively exchange heat with the heat-conducting rubber plate 20, thereby better cooling the circuit board, so that the circuit board and the electronic components on the circuit board are in a safe environment.

[0037] In the present embodiment, a stirring mechanism is also included; the stirring mechanism includes a motor 26 mounted on the water tank 25, the output end of the motor 26 is fixedly connected to a shaft 27, the shaft 27 penetrates the water tank 25 and is rotatably connected thereto, a plurality of first stirring rods 28 and a plurality of second stirring rods 33 are fixed on the shaft 27, a first mounting block 29 and a second mounting block 31 fixed on the shaft 27 are provided between the first stirring rod 28 and the second stirring rod 33, the first mounting block 29 is arranged close to the first stirring rod 28, a plurality of first spiral leaves 30 are fixed on the first mounting block 29, a plurality of second spiral leaves 32 are fixed on the second mounting block 31, and the spiral direction of the first spiral leaf 30 is opposite to the spiral direction of the second spiral leaf 32; since the range of the semiconductor refrigeration sheet 16 and the water tank 25 is limited, the motor 26 drives the shaft 27 to rotate, and the rotation of the shaft 27 drives the first stirring rod 28, the second stirring rod 33, the first mounting block 29, the second mounting block 31, the first spiral leaf 30, and the second spiral leaf 32 to rotate, such as Figure 5As shown, the first spiral blade 30 can be rotated to transport clean water to the left, and the flowing clean water can be mixed by the rotating first stirring rod 28. The second spiral blade 32 can be rotated to transport clean water to the right, and the transported clean water can be stirred and mixed by the second stirring rod 33. In this way, the low-temperature water cooled by the semiconductor refrigeration plate 16 and the water in other parts can be evenly mixed, so that the temperature of the clean water is uniform, thereby better exchanging heat for the circuit board.
