[0055] Specifically, the setting of the heat insulation cotton can effectively reduce the influence of the heat generated by the electric heating wire 5 on the inner wall of the box body 1, prevent the heat from being lost too quickly, and thus improve the heat preservation effect. At the same time, the heat insulation cotton can also reduce the corrosion of the electric heating wire 5 on the inner wall of the box body 1, and extend the service life of the box body 1.

[0056] In this embodiment, by providing heat insulation cotton between the inner wall of the box body 1 and the electric heating wire 5, the heat preservation effect of the heat preservation box 4 can be further improved, so that the food can be kept at a suitable temperature for a longer time in the heat preservation box 4. In addition, the provision of heat insulation cotton can also improve the safety performance of the heat preservation box 4, prevent the heat generated by the electric heating wire 5 from damaging the inner wall of the box body 1, and ensure the normal use of the heat preservation box 4.

[0057] In some embodiments, the meal delivery vehicle may further include an alarm, wherein the alarm is electrically connected to the control mechanism 7 .

[0058] Specifically, when the control mechanism 7 detects that the temperature in the incubator 4 is abnormal or the heating wire 5 fails, the alarm will be triggered to sound an alarm, reminding the staff to deal with it in time. In this way, the staff can find and solve the problem in time to ensure the normal operation of the meal delivery vehicle.

[0059] In this embodiment, by setting an alarm, the meal delivery vehicle can promptly issue an alarm when a problem occurs, thereby improving the safety and reliability of the meal delivery vehicle. At the same time, the setting of the alarm also enables the staff to more conveniently monitor the working status of the incubator 4, take timely measures, and ensure the smooth progress of the meal delivery work.
