The power supply module 26 is not limited to this example, and may be adjusted according to actual needs.
In one embodiment, as shown in fig. 1-2, a portable refrigeration device further includes a liquid level meter 14 disposed in the air duct 19 for determining whether the water level in the air duct 19 exceeds a predetermined value according to the internal water level and controlling whether water in the air duct 19 is drained; and the draft tube 13 is connected with the liquid level meter 14 and is used for discharging water in the air duct 19.
As an alternative embodiment, the gauge 14 comprises: the valve 12 is connected with the flow guide pipe 13 and used for controlling the opening and closing state of the flow guide pipe 13; the floating ball connecting rod 21 is connected with the valve 12, the floating ball connecting rod 21 is used for controlling the valve 12 to be opened and closed, and the floating ball connecting rod 21 is of a cross structure; a fixed wall surface 20 provided in the liquid level gauge 14; and the floating ball 22 is connected with the floating ball connecting rod 21 and is used for driving the floating ball connecting rod 21 to move on the track of the fixed wall surface 20, namely driving the floating ball connecting rod 21 to ascend and descend on the fixed wall surface 20.

As shown in fig. 1, in the portable refrigeration device, immediately after the ice cubes are placed in the ice storage chamber 1, the temperature of the ice cubes does not reach the melting temperature, and at this time, the cold energy of the ice cubes is completely transmitted through the heat pipe 4. Due to the continuous heat exchange, the ice storage chamber 1 reaches the melting point temperature, the ice blocks gradually melt into water, and the water flows down to the air duct 19 along the water discharge hole 2 and soaks the water curtain 15. The heat pipe 4 continues to exchange heat with the ice, and at the same time, the water adsorbed on the water curtain 15 further removes heat from the air by evaporation. When the ice blocks are completely melted into water, the water is completely transferred to the air duct 19 along the water discharge holes 2, and the heat of the air is taken away through the water evaporation on the water curtain 15, and the cold energy produced by the device is completely derived from the evaporation heat absorption of the water and the heat exchange between the air and the water. If the water level in the air duct 19 exceeds the predetermined value of the liquid level meter 14, the liquid level meter 14 will control the valve 12 to open, and part of the water will be discharged along the guide pipe 13. Compared with the traditional phase change refrigeration which can not fully utilize the cold energy of ice blocks, the water curtain 15 additionally arranged in the device can utilize the residual cold energy after ice melts. In addition, under the condition that ice blocks cannot be obtained, clear water can be added into the ice storage chamber 1, and the device becomes a small-sized air cooler and can also achieve the effect of cooling after operation.
As shown in fig. 1, in the portable refrigeration device provided by the present invention, only the fan 7 that provides electric energy to the power supply module 26 is needed, compared with the prior art, the energy consumption is high because a water pump is needed when the existing small portable refrigeration equipment works, the existing large ice refrigeration equipment needs to be connected with a compressor and an electromagnetic valve external device for refrigeration, the energy consumption is high, and the power supply used needs to be ac power, so that the portable refrigeration cannot be achieved due to too much limitation; therefore, the endurance time of the device is longer under the condition of the same battery capacity.
As shown in fig. 2-3, the floating ball connecting rod 21 is a cross structure, the left and right ends of the floating ball connecting rod 21 penetrate through the fixing wall 20 with the small slit 25 to be fixed with the limiting foot 23 and the valve 12, the front and rear ends are in a state of being attached to the fixing wall 20 but sliding, and the lower end is connected with the floating ball 22. The lower end of the liquid level meter 14 is not completely closed, part of the area is communicated with the air duct 19, and the water level in the air duct 19 is equal to the water level in the liquid level meter 14 because the liquid level meter 14 and the air duct 19 are in a communicated state. Under the action of buoyancy, the rising of the water level can drive the floating ball 22 and the floating ball connecting rod 21 to rise, and the floating ball connecting rod 21 is combined with the valve 12, so that the valve 12 is opened and closed. When the water level in the air duct 19 rises to exceed the warning line, the water is discharged to the outside along the flow guide pipe 13. When the water level is below the warning line, the valve 12 can automatically close under the action of gravity. With the aid of the limiting foot 23 and the fixing foot 24, the valve 12 can be kept open and closed to the appropriate extent. In addition, after the device finishes refrigerating, the valve 12 at the position of the draft tube 13 can be opened manually to realize complete discharge of accumulated water in the air duct, so that the device is smaller in weight and more convenient to carry.
According to the portable refrigerating device provided by the utility model, by utilizing the principle that ice blocks absorb heat in the melting process and the principle that ice blocks absorb heat in the water evaporation process and combining the operation of the fan, negative pressure is formed in the air channel to enable hot air to enter the air channel through the air inlet, the hot air exchanges heat with the ice blocks and water to achieve the refrigerating effect, and cold air is discharged through the air outlet, so that the requirements of complete refrigeration and portability of the ice blocks are met.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
