[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0023] Reference Figure 1 to Figure 7 : An outdoor multifunctional box, comprising a box body 10, specifically, as Figure 2 As shown, a heat insulation board 20 is provided in the box body 10, and a fan 21 and a semiconductor heating and cooling sheet 23 are provided on the heat insulation board 20. The fan 21 is provided on one side of the semiconductor heating and cooling sheet 23. The heat insulation board 20 divides the space in the box body 10 into two parts. The heat insulation board 20 is provided with a mounting hole, and the heat insulation board 20 and the semiconductor heating and cooling sheet 23 are connected through the mounting hole. Heat sinks 22 are connected to both sides of the semiconductor heating and cooling sheet 23, so that the two heat sinks 22 are respectively provided on one side of the heat insulation board 20. In this way, by providing the heat insulation board 20, the semiconductor heating and cooling sheet 23 is fixed inside the box body 10, which facilitates the connection between the semiconductor heating and cooling sheet 23 and the heat sinks 22 on both sides. At the same time, under the separation of the heat insulation board 20, the heat emitted from one side of the semiconductor heating and cooling sheet 23 will not affect the heat emitted from the other side, and other components can be supported.
[0024] The side wall of the box body 10 is provided with an air inlet 100, a first air outlet 101 and a second air outlet 102. Figure 1 and Figure 2 In the structure shown in the figure, the first air outlet 101 and the second air outlet 102 are respectively arranged on opposite sides of the box body 10, the air inlet 100 corresponds to the fan 21, and the first air outlet 101 and the second air outlet 102 both correspond to the air supply direction of the fan 21. The air supply direction of the fan 21 refers to the direction in which the airflow is blown toward the heat sink 22 when the fan 21 rotates (such as Figure 5 (direction indicated by the solid arrow in the figure).
[0025] When the power is turned on, a temperature difference is generated on the two sides of the semiconductor heating and cooling sheet 23, forming a cooling surface and a heating surface. The cold and hot energy on the two sides are respectively conducted to the heat sink connected to the surface, and at the same time, the fan 21 rotates, and the gas enters from the air inlet 100. Under the action of the fan 21, an air duct is formed, and the air flow blows the heat on the heat sink on one side of the partition out from the first air outlet 101, and the heat on the heat sink on the other side is dissipated from the second air outlet 102. It should be noted that the semiconductor heating and cooling sheet 23 is an existing device, and the specific principle will not be repeated. The first air outlet 101 and the second air outlet 102 are both micropores, and their aperture size and shape are not limited. For example, they can be multiple holes of various shapes such as small round holes, small elliptical holes, small square holes, etc., or they can be grille holes, as long as they do not hinder the heat from being delivered.
[0026] To improve the heat dissipation effect, refer to Figure 3 and Figure 4 In the connection structure shown, one side of the semiconductor heating and cooling fin 23 is connected to the first heat sink 221, and the other side of the semiconductor heating and cooling fin 23 is connected to the second heat sink 222. Furthermore, the surface area of the first heat sink 221 is greater than the surface area of the second heat sink 222. The larger surface area of the first heat sink 221 can accelerate the heat outflow under the action of the fan 24. When the side where the semiconductor heating and cooling fin 23 and the second heat sink 222 are connected is the cooling surface, the hot air is blown out from the first air outlet 101, and the cold air is dispersed from the second air outlet 102 on the other side of the box body. On the contrary, the hot air is dispersed from the second air outlet 102, and the cold air is blown out from the first air outlet 101, thereby realizing continuous cooling or heating functions, and the temperature on both sides of the box body 10 can be quickly adjusted. In actual use, it is only necessary to point the air outlet on one side of the box body to the place where heating or cooling is required, and the hot and cold air can be effectively transmitted to the place where the user needs.
[0027] A protrusion 105 is provided on one side of the box body 10. Figure 1 and Figure 2 As shown, a slot 106 is provided on the protrusion 105, and an air inlet 100 is provided at the outer edge of the slot 106. A mosquito coil or mosquito repellent can be inserted into the slot 106. When the mosquito coil is inserted into the slot 106, the gas entering the box body 10 along the air inlet 100 carries the mosquito repellent component, and then the fan 21 blows the gas out along the first air outlet 101, dispersing the mosquito repellent component outward, thereby playing the role of repelling mosquitoes around the box body 10.
[0028] The box body 10 also includes a laser lighting lamp 13. A first mounting groove 103 is provided on one side of the box body 10 along the length direction. The first mounting groove 103 corresponds to the shape of the laser lighting lamp 13. The laser lighting lamp 13 can be detachably inserted into the first mounting groove 103. Since the lamp body is movable, it can be used for long-distance lighting positioning and pointing, and can also be used as an emergency backup lamp. The lighting lamp can be taken out to adjust the lighting according to different situations and needs to meet different lighting needs. At the same time, the lighting lamp can be easily placed in the box body 10 and carried with the box body, without having to be placed in a backpack separately, and does not need to occupy space in the backpack.
[0029] The outer side of the box body 10 is also provided with an LED lighting lamp 14, which is fixed to the box body 10. When using the box body 10, the LED lighting lamp 14 can be directly turned on to provide sufficient lighting, which is convenient for the user to operate in a dim outdoor environment. In particular, when walking at night or in a dim environment, the box body 10 can be fixed on a backpack, and the outdoor environment can be identified without holding a lighting lamp.
[0030] A second mounting groove 104 is provided along the width direction on the other side of the box body 10. A hidden knife, such as a folding knife, can be placed in the second mounting groove 14. The shape of the second mounting groove 14 corresponds to the folding knife. The folding knife is folded and placed in the second mounting groove 14 to avoid mixing the knife with other daily necessities, to prevent accidental contact or injury caused by the knife, especially in an emergency, it can be quickly taken out for use without searching, further improving outdoor safety.
[0031] A buzzer is also fixed in the box body 10, and a plurality of through holes 107 are provided on one side of the box body 10, and the plurality of through holes 107 correspond to the buzzer. The buzzer is arranged in the box body 10, so that the box body 10 has an emergency rescue function. In an emergency, such as being trapped, in danger or in need of help, the buzzer is triggered so that the buzzer emits a high-frequency sound along the plurality of through holes 107, which can attract the attention of others and convey a distress signal. An automatic water-falling alarm can also be arranged in the box body 10 to monitor whether the user falls into the water and sound an alarm. Therefore, it helps to improve outdoor safety.
[0032] A charging interface is reserved on the box body 10, and the interface can be an interface such as Type-C or USB interface or several interfaces coexisting to realize functions such as power supply and data transmission. The power supply can be solar panel power generation, mechanical power generation, mobile power supply, vehicle power supply or ordinary household power supply. The box body 10 can be connected to a specific functional module to flexibly upgrade or use different additional functions in different outdoor scenes, and can also be removed when not in use to save power consumption or reduce weight. Therefore, the function of the box body 10 can be easily expanded at any time, making the box body 10 more multifunctional.
[0033] The multifunctional box can be used alone or in outdoor storage equipment that needs cooling, heating or heat preservation. For example, a backpack includes the multifunctional box as described above and a bag body 30. The bag body 30 can be made into different sizes and shapes as needed, such as a backpack, a shoulder bag, a small tent or a shoulder bag. Figure 6 The one-shoulder backpack shown in the figure is provided with the function of the box by placing the tools in a multifunctional box, and then fixing the multifunctional box on the bag body 30 of the one-shoulder backpack by sewing, buttoning, zipping or other means, so as to give the backpack the function of the box without occupying the internal space of the bag body 30. Specifically, one side of the box body 10 is arranged inside the backpack, and the other side is arranged outside the bag body 30. The items that need to be kept fresh are placed in the bag, and the multifunctional box is started so that the second air outlet 102 emits cold air, thereby reducing the temperature inside the bag body 30, and the purpose of keeping fresh and warm can be achieved in the backpack. Therefore, when the multifunctional box is connected to the backpack, there is no need to open multiple holes on the bag body 30, which simplifies the production process, helps to reduce production costs, and improves production efficiency. At the same time, when the box body 10 arranged on the outside blows out hot air along the first air outlet 101, it can also achieve a local insulation function in an emergency state, such as Figure 7 The backpack shown in the figure only needs to point the air outlet toward the place where heating is needed in an emergency such as after falling into water. Furthermore, a lifebuoy is also provided on the bag body 30, and the lifebuoy and the bag body 30 are connected by a drawstring. There is enough gas in the lifebuoy. If it accidentally falls into the water, the lifebuoy can provide buoyancy. The outer side of the lifebuoy can be set to a brighter color, so that the bag body 30 can provide additional identification. Therefore, the backpack has various functions. It not only has heating and cooling effects, but also can facilitate the storage of lighting, knives and charging tools and use in outdoor emergency situations. It is easy to use, realizes multiple uses of one bag, adapts to different environmental conditions and emergency needs, and enhances the safety and convenience of users outdoors. At the same time, the overall structure is simple, and the overall design can reasonably utilize the space inside and outside the box body 10, which is conducive to reducing the volume of the product. It is compact and portable and will not affect the space for other items inside the backpack.
[0034] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
