The existing cooling and heating methods such as compressors can achieve the function, but the volume is relatively large and cannot be implemented on a small cigar box. There is an urgent need for a small device to achieve cooling and heating. Utility Model Content

DETAILED DESCRIPTION

[0022] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 A constant temperature cigar box comprises a box body 1, a cigar holder 2 is arranged in the box body 1, the cigar holder 2 is evenly distributed with a plurality of semicircular grooves 3, a rectangular groove 4 is arranged at the bottom of the semicircular groove 3, a heat spreader 5 is arranged on the lower end wall of the cigar holder 2, the heat spreader 5 covers the rectangular groove 4, the setting of the rectangular groove 4 ensures the effective support of the cigar, and at the same time makes the heat transfer of each cigar more uniform, and the setting of the rectangular groove 4 improves the space utilization rate in the box body 1.

[0024] Reference Figure 2 A semiconductor refrigeration sheet 6 is arranged on the lower end wall of the heat spreader 5, a heat sink 7 is arranged on the lower end wall of the semiconductor refrigeration sheet 6, and a flow fan 8 is arranged on the lower end wall of the heat sink 7. After the semiconductor refrigeration sheet 6 is powered on, its heat exchange principle adopts the existing technology, and N-type and P-type semiconductors are arranged inside to generate heat, and the flow fan 8 can take away the heat.

[0025] Reference Figure 1A box cover 11 is hinged on one side of the box body 1, and the temperature should not be lost after the box cover 11 is buckled with the box body 1.

[0026] Reference Figure 2 , 3 The semiconductor refrigeration sheet 6 is provided with a negative electrode wire 9, and the semiconductor refrigeration sheet 6 is provided with a positive electrode wire 10. The negative electrode wire 9 and the positive electrode wire 10 are connected to a battery slot 12. A battery 13 is installed in the battery slot 12. A conventional metal conductive sheet is used between the battery slot 12 and the wire to power the battery. The battery 13 is a lithium battery. The negative electrode wire 9 and the positive electrode wire 10 are connected to the battery slot 12. By flipping the battery 13, the battery 13 is flipped in the battery slot 12 so that the battery 13 and the negative electrode wire 9 and the positive electrode wire 10 of the semiconductor refrigeration sheet 6 are reversely connected. When the ambient temperature is high in summer, the negative electrode wire 9 and the positive electrode wire 10 are connected positively, and the semiconductor refrigeration sheet 6 is cooled. When the ambient temperature is low in winter, the negative electrode wire 9 and the positive electrode wire 10 are reversely connected, and the semiconductor refrigeration sheet 6 is heated. The battery is removed in spring and autumn.

[0027] Reference Figure 1 The cigar holder 2 is a rectangular plate embedded in the box body 1 to ensure the stability of the cigar holder 2.

[0028] The semicircular groove 3 can be used to place a cigar, and the shape of the semicircular groove 3 can adapt to the cylindrical shape of the cigar.

[0029] The rectangular groove 4 is located directly below the semicircular groove 3. The rectangular groove 4 is opened directly below to ensure that the heat of the cigar flows from the bottom and the center to the heat diffusion plate 5 during heat exchange, and the heat transfer effect is significant.

[0030] The area of ​​the heat spreader 5 is larger than that of the cigar holder 2 , ensuring that the heat of the cigar holder 2 can be completely transferred to the heat spreader 5 .

[0031] The lower end wall of the rectangular groove 4 is fitted with the heat spreader 5 , so that the cigar can be in close contact with the heat spreader 5 , ensuring the heat transfer efficiency, while improving the space utilization rate in the box body 1 and reducing the size of the box body 1 .

[0032] The heat spreader 5 is made of copper, which has good heat transfer efficiency.

[0033] Reference Figure 2 The semiconductor cooling sheet 6 has the same size as the heat spreader 5 , ensuring that the heat of the heat spreader 5 can be evenly absorbed by the heat spreader 5 .

[0034] The heat sink is centrally arranged on the semiconductor cooling sheet 6. The heat center in the box body 1 is larger than the surroundings, so the central arrangement ensures that heat will not gather in the center.

[0035] Working principle:

[0036] A large-area heat spreader 5 is placed on the inner wall of the cigar box body 1, and the cold end of the semiconductor refrigeration sheet 6 is attached to the outer side of the heat spreader 5. The hot end of the semiconductor refrigeration sheet 6 is connected to a heat sink 7. An axial flow fan 8 is added to the outer side of the heat sink 7 to enhance heat dissipation, actively blow away the heat or cold generated by the semiconductor refrigeration sheet 6, and make the semiconductor refrigeration sheet 6 work in the best state.

[0037] When the temperature in the cigar box is higher than the set temperature value, the semiconductor refrigeration chip 6 is energized in the forward direction, and the box cavity is cooled. The heat generated at the hot end of the semiconductor refrigeration chip 6 is actively blown away by the fan through the heat sink 7. When the temperature in the cigar box is lower than the set temperature value, the semiconductor refrigeration chip 6 is energized in the reverse direction, and the box cavity is heated. The cold generated at the hot end of the semiconductor refrigeration chip 6 is actively blown away by the fan through the heat sink 7.

[0038] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
