[0033] As described in the background, the existing industrial air cooler usually uses alternating current for power supply, and if the alternating current is maintained or limited, the air cooler will stop running and easily cause the temperature in the cold storage to rise, thereby affecting the storage of fruits and vegetables.

[0034] Based on the above reasons, to solve the above problems, the utility model provides the following technical scheme:

[0035] Embodiment 1,

[0036] Please refer to the drawings attached Figure 1 , the drawings attached Figure 4 , the drawings attached Figure 5 and the drawings attached Figure 7 An evaporative air cooler, comprising a main body shell 1, provided with a channel and a rotating fan blade 8 in the channel;

[0037] The upper water tank 3 is arranged at the top of the main body shell 1 and the refrigerant liquid is placed in the upper water tank 3, and the power storage module 17 is arranged at the bottom of the upper water tank 3, and the refrigerant liquid and the power storage module 17 are kept separate.

[0038] The top of the upper water tank is concave and has an annular groove, and the annular groove is used for placing refrigeration liquid to form a liquid medium flow channel 12. The annular groove has a boss 13 at the inner end. The bottom of the upper water tank has a containing groove 15 corresponding to the boss 13. The power storage module 17 is fixed in the containing groove 15.

[0039] A wet curtain 9 is arranged in the passage on both sides of the fan blade 8. The wet curtain 9 is communicated with the bottom of the liquid medium flow channel 12 and has an electric control valve at the communication position. A backwater groove 11 is arranged at the bottom of the passage of the main body shell 1 and corresponds to the wet curtain 9. A lower water tank 19 is arranged at the bottom of the main body shell 1 and is detachably installed at the bottom of the main body shell 1. The lower water tank 19 is communicated with the backwater groove 11. The lower water tank 19 has a backwater pipe and a pump body. The backwater pipe and the pump body are used for pumping water in the lower water tank 19 to the liquid medium flow channel 12 of the upper water tank 3. When the lower water tank has no water or the water level is too low, the pump body automatically stops working.

[0040] According to the above, the fan blade 8 introduces external air from one end of the passage, passes through the wet curtain 9, and then discharges the air from the other end to realize air cooling, so as to cool, humidify and dustproof the inhaled air and blow humid and clean cool air at the air outlet end.

[0041] In the embodiment, the main body shell 1 further has a motor for driving the fan blade 8 to rotate automatically. The motor is electrically connected with the power storage module 17 in the containing groove 15.

[0042] In the embodiment, the inner wall of the liquid medium flow channel 12 further has a liquid level sensor, a water inlet pipe and a water inlet valve connected with an external water source. When the liquid level in the liquid medium flow channel 12 is too low, the water inlet valve and the water inlet pipe can timely supplement water.

[0043] In the embodiment, the upper water tank 3 is integrally formed to ensure the separation of the power storage module 17 and the refrigeration liquid and avoid liquid leakage into the power storage module 17.

[0044] Further, the power storage module 17 is a storage battery (such as a lithium battery with long service life and high energy density).

[0045] The cold air machine can be powered by external industrial AC power to the power storage module during use, and the motor of the fan blade 8 is powered at the same time. If the industrial AC power is lost, the power storage module supplies power to the motor in time, thereby avoiding the temperature rise of the cold storage caused by the stop of the fan, and in the refrigeration process, cold water is pre-supplied into the liquid medium flow channel 12, and when the liquid level is appropriate, the motor drives the fan blade 8 to rotate, drives the air in the cold storage to flow, and opens the electric control valve between the wet curtain 9 and the bottom of the liquid medium flow channel 12, so that the cold water in the liquid medium flow channel 12 falls on the wet curtain 9. Combined with the air passing through the wet curtain 9, the air is cooled and the humidity of the air is increased after the water evaporates, and the air is discharged from the air outlet, thereby achieving the effect of cooling and humidifying. The water droplets on the wet curtain 9 fall into the lower water tank 19 at the lower end of the backwater tank 11, and are pumped back to the liquid medium flow channel 12 of the upper water tank 3, thereby realizing the recycling of the cooling water.

[0046] When the industrial AC power is normally powered, the industrial AC power supplies power to the motor and charges the power storage module at the same time. When the power storage module is fully charged, the charging of the power storage module is automatically cut off, and only the industrial AC power is supplied to the motor, thereby avoiding the disadvantage that the power storage module is first charged and then the power storage module supplies power to the motor. When the power is off, the battery supplies power to the motor, thereby prolonging the service life of the battery
