[0033] The utility model provides an air cooler with double water tanks.

[0034] Reference Figures 1 to 4 In an embodiment of the present invention, a cooling fan with a double water tank includes:

[0035] Box 10;

[0036] A water tank assembly 20 is provided in the box body 10, and the water tank assembly 20 includes a first water tank 21 and a second water tank 22, wherein the first water tank 21 and the second water tank 22 are adjacently arranged;

[0037] A water curtain mechanism 30 is provided in the box body 10 , wherein the water inlet side of the water curtain mechanism 30 is connected to the first water tank 21 , and the liquid in the first water tank 21 is transported to the water curtain mechanism 30 ;

[0038] The evaporator 40 and the water collecting pan 50 are arranged in the box body 10. The evaporator 40 is connected to the water collecting pan 50. The water collecting pan 50 collects the condensed water generated by the evaporator 40. The water collecting pan 50 is connected to the second water tank 22 to allow the condensed water to flow back into the second water tank 22.

[0039] The present invention provides a dual-tank air cooler with an automatic water supply function. It primarily consists of the following components: The housing 10 serves as the basic framework for the entire device, upon which other components are mounted. The water tank assembly 20 includes two independent water tanks (a first tank 21 and a second tank 22). This design primarily aims to recycle water. The first tank 21 provides water to the drencher mechanism 30, while the second tank 22 collects condensed water returning from the water collection tray 50. The drencher mechanism 30 extracts water from the first tank 21, forming a water curtain as air passes through it, increasing humidity and lowering temperature. This is one of the primary cooling methods used in dual-tank air coolers. Condensed water is generated by the evaporator 40 and the water collection tray 50 during operation. This condensed water is collected by the water collection tray 50 and ultimately flows into the second tank 22, effectively recycling water resources. The first tank 21 provides a stable water source for the drencher mechanism 30, ensuring its continued and effective operation, thereby enhancing the cooling effect. The second water tank 22 serves as a buffer zone, storing condensed water recovered from the evaporator 40. The condensed water in the second water tank 22 can be regularly discharged or treated to prevent long-term accumulation and deterioration of water quality. By designing the first and second water tanks 21 and 22 separately, this dual-tank air cooler not only ensures the efficient operation of the drencher mechanism 30, but also effectively manages and utilizes condensed water, improving system stability and reliability. Furthermore, the drencher mechanism 30, combined with the evaporator 40, not only effectively lowers the indoor temperature but also maintains a certain humidity, providing a more comfortable environment. The automatic water supply mechanism reduces the frequency of manual water additions, improving user convenience. A rational water circulation system helps reduce the risk of equipment damage due to water shortages and also avoids corrosion caused by excessive water accumulation. Specifically, when the dual-tank air cooler is turned on, the control system checks whether the water level in the water tank assembly 20 is sufficient. If the water level is insufficient, the device may issue an alarm prompting the user to add water, or, in advanced models, water can be directly added through a connected automatic water supply system. The first water tank 21 delivers water to the drencher mechanism 30. The water curtain mechanism 30 is usually composed of multiple layers of water-absorbing materials, such as paper or fiber water curtain plates, and water will be evenly distributed when it flows through these materials. Hot air from outdoors or indoors can be sucked into the air cooler with double water tanks by the fan. When these air pass through the moistened water curtain plates, the air temperature drops and the humidity increases due to the evaporation of water. The treated cool air is blown into the room to achieve a cooling effect. The evaporator 40 will produce condensed water during the cooling process. The condensed water drips along the surface of the evaporator to the water collection tray 50 below. The condensed water collected in the water collection tray 50 is guided to the second water tank 22 through a pipe. Furthermore, the water tank assembly 20 is provided with an installation port for installing a compressor.It is understandable that the installation port can be set at the first water tank 21, or at the second water tank 22, or at the connection between the first water tank 21 and the second water tank 22.

[0040] Reference Figures 1 to 4 In an embodiment of the present invention, the automatic water supply mechanism also includes a water adding pump 23, which is provided in the second water tank 22. The water inlet end of the water adding pump 23 is connected to the water source, and the water outlet end of the water adding pump 23 is connected to the first water inlet 24 of the first water tank 21. The water inlet side of the water curtain mechanism 30 is connected to the first water inlet 24.

[0041] The water supply pump 23 is installed on the second water tank 22. The water inlet end is connected to the external water source, and the water outlet end is connected to the first water inlet 24 of the first water tank 21. The water supply pump 23 automatically replenishes the water in the first water tank 21 from the external water source to ensure that the water curtain mechanism 30 always has sufficient water supply. Users do not need to add water manually frequently, which improves the convenience and degree of automation of use. Although the condensed water collected in the second water tank 22 does not flow directly back to the first water tank 21, it can be used in other ways, such as regular discharge or for other purposes. The water in the first water tank 21 is always kept clean, ensuring the efficient operation of the water curtain mechanism 30. The water level of the first water tank 21 is monitored by a sensor. When the water level is too low, the water supply pump 23 automatically starts to replenish water from the external water source. This ensures that the water curtain mechanism 30 and the water supply pump 23 will not be damaged due to lack of water, thereby improving the reliability and life of the system. Specifically, the water pump in the first water tank 21 starts to transport water to the water curtain mechanism 30. The water curtain mechanism 30 reduces the temperature of the air entering the air cooler with dual water tanks and increases the humidity through evaporation. The evaporator 40 produces condensed water during the cooling process. The condensed water drips along the surface of the evaporator to the water collection tray 50. The condensed water collected by the water collection tray 50 is guided to the second water tank 22 through a pipe. The condensed water in the second water tank 22 can be discharged or treated regularly to prevent the water quality from deteriorating. If the system design permits, the water in the second water tank 22 can also be used for other non-critical water needs, such as cleaning or irrigation. The water in the first water tank 21 is automatically replenished from an external water source by the water adding pump 23. This design not only ensures the continuous and efficient operation of the water curtain mechanism 30, but also improves the automation level of the system and the user experience. At the same time, the recycling of condensed water also reflects the concept of environmental protection and energy saving.

[0042] Reference Figures 1 to 4 In an embodiment of the present invention, a first scale line and a second scale line are provided on the outer surface of the water adding pump 23 at intervals. The first scale line is used to indicate the lowest level of the liquid in the first water tank 21, and the second scale line is used to indicate the highest level of the liquid in the second water tank 22.

[0043] Setting the highest and lowest indicator lines on the water pump 23 to visually display the water level can further improve the safety and reliability of the system. The highest indicator line ensures that the water pump 23 will not continue to operate when the water level is too high, avoiding overflow and equipment damage. This prevents overflow accidents caused by excessively high water levels and protects the safety of equipment and the operating environment. The lowest indicator line ensures that the water pump 23 will not start when the water level is too low, avoiding dry heating of the water pump and equipment damage. Ensuring that the water pump 23 operates within the appropriate water level range improves the reliability and lifespan of the system.

[0044] Reference Figures 1 to 4 In the embodiment of the present utility model, the water adding pump 23 includes a water pump body and a liquid level sensor, the liquid level sensor is used to sense the water level of the second water tank 22, and the water inlet end and the water outlet end are respectively provided on the water pump body;

[0045] The liquid level sensor and the water pump body are both electrically connected to a control device, and the control device receives communication data from the liquid level sensor and regulates the opening and closing of the water pump body to replenish water for the first water tank 21;

[0046] When the water level of the second water tank 22 is lower than the detection position of the liquid level sensor, the water pump body replenishes water for the first water tank 21 .

[0047] This solution monitors the water level in the second water tank 22 in real time, ensuring the system can respond promptly to water level changes. Based on data from the liquid level sensor, the water pump 23 is automatically activated, achieving intelligent management. When the water level in the second water tank 22 falls below the set value, the water pump 23 starts pumping water from an external source to replenish the first water tank 21. This eliminates the need for frequent manual water additions, improving user convenience and automation. The liquid level sensor and control device work together to ensure the water level in the first water tank 21 remains within a reasonable range, preventing damage to the water curtain mechanism 30 due to water shortage. When the water level in the second water tank 22 returns to normal, the water pump 23 automatically stops, avoiding over-filling and water waste. The liquid level sensor monitors the water level in the water tank in real time, and the control device automatically controls the activation and deactivation of the water pump 20, achieving fully automated water supply. Precise water level control avoids water waste caused by oversupply and reduces power consumption. Specifically, the liquid level sensor continuously monitors the water level in the second water tank 22. When the water level in the second water tank 22 drops to a preset minimum level, the liquid level sensor sends a signal to the control device. Upon receiving the signal, the control device activates the water supply pump 23. This pump draws water from the water source and delivers it to the first water tank 21 through the outlet. When the water level in the second water tank 22 reaches a preset upper safety limit, the liquid level sensor sends another signal to the control device, which shuts down the water supply pump 23. The system continuously monitors the water level, maintaining it within a set range and ensuring stable operation of the water supply system.

[0048] Reference Figures 1 to 4 In an embodiment of the present utility model, the water collecting pan 50 includes a water collecting pan body 51, a first mounting portion 52 and a second mounting portion 53. The water collecting pan body 51 is covered at the water inlet 23 and the second water inlet 25 of the second water tank 22. The first mounting portion 52 and the second mounting portion 53 are both extended along the bottom wall near the second box body 12. The first mounting portion 52 is provided with a first mounting cavity 54, and the water pump 23 is accommodated in the first mounting cavity 54. The first mounting cavity 54 is communicated with the first water inlet 24 so that the water pump 23 can replenish water for the first water tank 21. The second mounting portion 53 is provided with a second mounting cavity 55, and the evaporator 40 is accommodated in the second mounting cavity 55. The second mounting cavity 55 is communicated with the second water inlet 25.

[0049] The first mounting portion 52 is provided with a first mounting cavity 54 for accommodating the water supply pump 23. This ensures that the water supply pump 23 is fixed in position and connected to the first water inlet 24 of the first water tank 21, facilitating water delivery. The second mounting portion 53 is provided with a second mounting cavity 55 for accommodating the evaporator 40. This ensures that the evaporator 40 is fixed in position and connected to the second water inlet 25 of the second water tank 22, facilitating the collection and recovery of condensed water. By separately mounting the water supply pump 23 and the evaporator 40 in the first mounting portion 52 and the second mounting portion 53 of the water collection tray 50, a compact layout is achieved, reducing the overall size of the equipment and conserving installation space. This integrated design reduces the length and complexity of piping, mitigates the risk of pipeline leakage, and improves system reliability. The design of the water collection tray 50 facilitates installation of the water supply pump 23 and evaporator 40, reducing installation steps and time. This integrated design reduces the overall size of the equipment and conserves installation space. The design of the water collection tray 50 also facilitates installation and maintenance of the water supply pump 23 and evaporator 40, making it easier for users to operate the system. If the water pump 23 or evaporator 40 needs to be repaired or replaced, the water collection pan 50 can be directly removed, facilitating maintenance and inspection. It will be appreciated that the first mounting portion 52 is designed as a closed box-like structure with a first mounting cavity 54 internally provided for accommodating the water pump 23. This box-like structure provides excellent protection against the ingress of dust and impurities. The second mounting portion 53 is similarly designed as a closed box-like structure with a second mounting cavity 55 internally provided for accommodating the evaporator 40. This box-like structure provides excellent thermal insulation and moisture resistance. Alternatively, the first mounting portion 52 may be designed as an open frame structure with a first mounting cavity 54 internally provided for accommodating the water pump 23. This open structure facilitates inspection and maintenance. The second mounting portion 53 may be designed as an open frame structure with a second mounting cavity 55 internally provided for accommodating the evaporator 40. This open structure facilitates heat dissipation and ventilation. Alternatively, the first and second mounting portions 52, 53 may be integrated with the water collection pan body 51 to form a single, integral structure.

[0050] Reference Figures 1 to 4 In the embodiment of the present invention, the first water inlet 24 is opened at the top of the first water tank 21, and the second water inlet 25 is opened at the top of the second water tank 22.

[0051] The top water inlet design effectively prevents overflow and reduces safety hazards. It conveniently removes air from the water tank, preventing air bubbles from accumulating and affecting water flow and equipment operation, thereby improving system stability and reliability. The top water inlet facilitates connection and inspection, simplifying installation and maintenance. It evenly distributes water throughout the tank, ensuring a balanced water level. It also reduces turbulence as water enters the tank, minimizing noise and enhancing the user experience.

[0052] Reference Figures 1 to 4 In the embodiment of the present invention, the water tank assembly 20 is separated into the first water tank 21 and the second water tank 22 by a partition 26, and the first water tank 21 and the second water tank 22 are arranged side by side.

[0053] The water tank assembly 20 is divided into two independent water tanks by a partition 26. These two separate, side-by-side tanks achieve a compact layout, reduce the overall size of the equipment, and conserve installation space. The side-by-side arrangement of the water tanks provides greater structural stability, reducing vibration and sway caused by water level fluctuations. The separation of the first and second water tanks 21, 22 prevents impurities and microorganisms in the condensate from contaminating the clean water, ensuring the proper operation of the water curtain mechanism 30.

[0054] Reference Figures 1 to 4 In the embodiment of the present invention, the partition 26 is provided with an air-avoiding gap, and the first mounting portion 52 is at least partially accommodated in the air-avoiding gap.

[0055] By providing a clearance notch in the partition 26, a portion of the first mounting portion 52 can be nested within the clearance notch, reducing the space occupied by the first mounting portion 52 and making the overall device layout more compact. This compact layout reduces the overall size of the device, saving installation space and making it particularly suitable for applications with limited space. The clearance notch provides an additional fixed support point, ensuring that the first mounting portion 52 is more stable during operation and reducing vibration and shaking. The clearance notch design in the partition 26 enhances the rigidity of the entire water tank assembly and improves the stability of the structure.

[0056] Reference Figures 1 to 4 In an embodiment of the present invention, a water outlet 27 and a diversion slope are provided at the bottom of the second water tank 22 for discharging the liquid in the second water tank 22 . The liquid in the second water tank 22 is discharged from the water outlet 27 through the diversion slope.

[0057] The design of the diversion slope ensures that the liquid in the second water tank 22 flows smoothly toward the water outlet 27, preventing it from stagnating at the bottom of the tank. Water outlet 27 is located at the lowest point of the diversion slope, ensuring complete liquid drainage and minimizing residual liquid. The design of the diversion slope and water outlet 27 minimizes residual liquid in the water tank, preventing any remaining condensed water from deteriorating, generating odors, or breeding bacteria. This design maintains the cleanliness of the water tank, extending the life of the equipment, and reducing maintenance costs.

[0058] Reference Figures 1 to 4 In an embodiment of the present invention, the water tank automatic water supply structure further includes a water pump 60 , and the water pump 60 is located in the second water tank 22 .

[0059] The pump 60 is located in the second water tank 22 and is used to pump condensed water from the second water tank 22 and transport it through a pipeline to a required location, such as the first water tank 21 or other water points. The pump 60 evenly transports the condensed water from the second water tank 22 to the first water tank 21, ensuring a stable water level in the first water tank 21 and preventing water level fluctuations.

[0060] Reference Figures 1 to 4 In an embodiment of the present invention, the water tank automatic water supply structure further includes a pressure pump 70 , and the pressure pump 70 is located in the first water tank 21 .

[0061] The pressure pump 70 is located in the first water tank 21 and is used to pressurize the water in the first water tank 21, ensuring that the drencher mechanism 30 and other water points receive sufficient water pressure, ensuring even water distribution and efficient use. By pressurizing the water in the first water tank 21 through the pressure pump 70, the drencher mechanism 30 receives stable water pressure, ensuring even water distribution and improving the cooling effect.
