[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] The utility model provides a constant temperature control cabinet, comprising:

[0033] Cabinet 1, used to carry external electrical components;

[0034] The cabinet door 2 is hinged to the cabinet body 1 and is used to seal the cabinet body 1. The cabinet door 2 can prevent outsiders from accidentally touching the electrical components inside the cabinet body 1;

[0035] a cavity 3 formed in a side wall of the cabinet 1;

[0036] The electric heating wire 4 is arranged in the cavity 3 and is connected to an external power supply device, which can supply power to the electric heating wire 4 to heat it;

[0037] The constant temperature control mechanism is provided on the cabinet door 2 and is electrically connected to the electric heating wire 4 for controlling the heating of the electric heating wire 4 .

[0038] Specifically, the constant temperature control mechanism includes;

[0039] The controller 5 is provided on the outer wall of the cabinet door 2 and is electrically connected to the electric heating wire 4. The controller 5 is fixedly mounted on the outer wall of the cabinet door 2 and can remain fixed. At the same time, the controller 5 can control the electric heating wire 4 to turn on or off, so that the electric heating wire 4 can heat the space inside the cabinet 1.

[0040] The temperature sensor 6 is provided on the inner wall surface of the cabinet door 2 and is electrically connected to the controller 5 for detecting the temperature inside the cabinet 1. The temperature sensor 6 is fixedly mounted on the inner wall surface of the cabinet door 2 and can detect the temperature inside the cabinet 1. At the same time, the detected data can be transmitted to the controller 5 so that the controller 5 can control the heating wire 4 to heat. The controller 5 can preset a value. When the temperature sensor 6 detects that the temperature inside the cabinet 1 is lower than the preset value, the controller 5 controls the heating wire 4 to heat. When the temperature inside the cabinet 1 reaches the preset value, the controller 5 controls the heating wire 4 to stop heating. At this time, the temperature inside the cabinet 1 is in a constant temperature state.

[0041] The ventilation structure is provided on the cabinet body 1 and is used to allow air to circulate inside the cabinet body 1 .

[0042] Specifically, the ventilation structure includes;

[0043] The air outlet is formed on the cabinet door 2 and can allow the air in the cabinet 1 to flow out of the cabinet 1;

[0044] The dustproof net 7 is arranged in the air outlet and is fixedly installed in the air outlet to prevent external pollutants from entering the cabinet 1;

[0045] A through-hole 8 is formed on the upper wall of the cabinet 1. The through-hole 8 allows outside air to enter the cabinet 1. At the same time, the air inside the cabinet 1 can circulate under the action of the air outlet.

[0046] The shell 9 is provided on the upper end surface of the cabinet 1 and is connected to the through port 8. The lower end of the shell 9 is welded to the upper end surface of the cabinet 1 so as to be relatively fixed.

[0047] The fan 10 is rotatably arranged on the inner upper end surface of the housing 9;

[0048] The driving member 11 is provided on the upper end surface of the housing 9 and is used to drive the fan 10 to rotate. The driving member 11 is a motor, and the output end is fixedly connected to one end of the fan 10 to drive the fan 10 to rotate.

[0049] Specifically, an air inlet 12 is formed on the upper wall of the shell 9, and a filter 13 is arranged inside the air inlet 12. The air inlet 12 can facilitate the entry of external air into the shell 9, and the filter 13 can filter the dust in the air to prevent dust from entering the shell 9 and polluting the space inside the cabinet 1.

[0050] Specifically, a rock wool board 14 is provided on one end face of the cavity 3 , and the rock wool board 14 is fixedly installed on one end face of the cavity 3 , which can play a role in fire prevention and heat preservation, and prevent the heat generated by the electric heating wire 4 from overflowing.

[0051] Working principle: The staff can preset a value on the controller 5. When the temperature sensor 6 detects that the temperature inside the cabinet 1 is lower than the preset value of the controller 5, the temperature sensor 6 transmits an electrical signal to the controller 5, so that the controller 5 controls the electric heating wire 4 to heat, so that the temperature of the space inside the cabinet 1 increases. When the space temperature inside the cabinet 1 reaches the preset value, the controller 5 controls the electric heating wire 4 to stop heating, so that the space inside the cabinet 1 is in a constant temperature state. When the staff needs to operate the electrical components in the cabinet 1, the staff starts the driving member 11, and the output end of the driving member 11 drives the fan 10 to rotate, so that the outside air enters the shell 9 from the air inlet 12, and then flows into the cabinet 1 from the through port 8, blowing the heated air in the cabinet 1 so that it is discharged from the air outlet to the outside of the cabinet 1, making it convenient for the staff to operate the electrical components.
