When the temperature is detected to exceed the threshold, the driver 7 drives the adjustment block 806 to move axially, increasing the installation angle of the blade 811 and the air inlet space, and at the same time drives the throttle plate 605 to move downward to expand the cross-sectional area of ​​the liquid outlet channel.

[0023] In this embodiment, when the device is started, the water pump 5 pumps the water in the water storage chamber to the water delivery pipe 502 through the water pumping pipe 501. The water flows through the serpentine water delivery pipe 502 and the airflow generated by the fan mechanism 8 for precooling, and then enters the throttle 6 and flows evenly into the wet curtain 3 through the water outlet 406 to moisten the wet curtain 3. The airflow generated by the fan mechanism 8 will reduce the airflow temperature after flowing through the wet curtain 3. The airflow with reduced temperature is discharged outward through the air outlet 101 of the housing 1 to reduce the indoor temperature. In the initial state, the push plate 603 is at a high position, the cross-sectional area of ​​the liquid outlet channel between the throttle plate 605 and the annular protrusion 602 is small, and the water flows into the water distributor 4 at a lower flow rate through the water inlet pipe 401 and is evenly distributed to the wet curtain 3. At this time, the fan motor 801 drives the shaft 802 to rotate, and the blade 811 runs at a default inclination angle to form a basic air volume; The temperature sensor is electrically connected to the control system. The temperature sensor detects the air flow temperature on the air inlet side. By monitoring the air flow temperature on the air inlet side, the room temperature can be monitored in real time. When the temperature sensor detects that the air inlet temperature exceeds the threshold, the driver 7 is started, and the driver 7 drives the adjustment block 806 to slide axially along the inner cavity of the shaft rod 802. The support rod 808 is meshed and linked with the rack 810 through the gear 809, pushing the blade 811 to increase the inclination angle and move away from the air inlet, thereby expanding the air intake space and increasing the air volume. At the same time, the driver 7 pushes the push plate 603 to move downward, driving the throttle plate 605 to move downward to expand the cross-sectional area of ​​the liquid outlet channel, and the water flow rate is increased synchronously, thereby increasing the wetness of the wet curtain 3 and strengthening the evaporation heat absorption effect. The temperature sensor is linked to the driver 7 to synchronously adjust the air volume and water flow. At high temperatures, the inclination angle of the blade 811 is increased to increase the air volume, and the water flow is increased to enhance evaporation. The cooling capacity is improved without increasing the power of the fan motor 801, thus avoiding the high energy consumption problem of traditional equipment.

[0024] Preferably, the front side wall of the housing 1 is provided with a rectangular air outlet 101 and an air outlet grille 102; the rear side wall is provided with an air inlet 105 and a detachable dust screen 106, and the dust screen 106 is made of a washable nylon material with a G3 grade filtration accuracy; the left side wall is provided with an inspection port and a detachable inspection cover 103 is installed; When the equipment is running, external air enters from the air inlet 105 on the rear side wall of the shell 1, and first passes through the detachable dustproof net 106 to intercept impurities such as dust and particulate matter to form a clean airflow; the filtered airflow passes through the moist wet curtain 3 under the suction action of the fan mechanism 8, and is cooled by absorbing heat through water evaporation. The cooled cold air is discharged through the rectangular air outlet 101 on the front side wall, and the air outlet grille 102 guides the airflow to diffuse evenly through its inclined blades 811, thereby expanding the air supply coverage; when the dustproof net 106 accumulates dust due to long-term use, resulting in an increased pressure drop, the user can open the inspection cover 103 to replace it, and at the same time, the internal water pump 5, throttle 6 and other components can also be quickly inspected or replaced.

[0025] Preferably, a water tank 2 is provided in the water storage cavity, a groove is provided on the front side of the water tank 2, and limit grooves are symmetrically provided on the left and right sides of the water tank 2. A limit block that slides with the limit groove is provided on the inner wall of the water storage cavity to limit the water tank 2 from completely detaching, and the water extraction pipe 501 is a hose; Refrigeration fins 104 are arranged on the outer periphery of the housing 1, with the hot end of each refrigeration fin 104 facing the outside of the device and the cold end contacting the outer wall of the water tank 2. The refrigeration fins 104 are semiconductors and are electrically connected to the temperature sensor through the control system.

[0026] In this embodiment, when the device is running, the water tank 2 in the water storage cavity is continuously supplied with water by the water pump 5 through the soft water pumping pipe 501; when cleaning or adding water is needed, the user pulls the water tank 2 outward through the pull groove on the front side, and the limit groove and the limit block on the inner wall of the water storage cavity slide together to pull out the water tank 2. After the operation is completed, the water tank 2 is pushed back to automatically reset. During this process, the water pumping pipe 501 is always in the water tank 2; In addition, when the indoor temperature is too high, the temperature sensor can start the refrigeration plate 104 through the control system, and its cold end directly contacts the outer wall of the water tank 2 to lower the water temperature in the water tank 2. After the low-temperature water flows through the water supply pipe 502 and enters the wet curtain 3, the evaporation heat absorption efficiency is improved, which can further enhance the cooling effect.

[0027] Preferably, the water supply pipe 502 is arranged between the fan mechanism 8 and the wet curtain 3, and forms a wavy path from bottom to top through multiple arc bends; the wavy path prolongs the residence time of the water flow in the water supply pipe 502, improves the heat exchange efficiency, makes the water temperature entering the wet curtain 3 lower, and further enhances the cooling effect.

[0028] Preferably, the driver 7 includes an electric push rod 9, the top of the electric push rod 9 is fixed to the top of the housing 1, and a mounting plate 901 is fixed to the bottom of the electric push rod 9. One end of the bottom of the mounting plate 901 is provided with a driver 7 for pushing the push plate 603 to move, and the other end is provided with a regulating component for driving the adjusting block 806 to slide axially; The driver 7 includes a liquid storage tank 701, in which hydraulic medium is encapsulated and connected to the top of the housing 601 through a bottom rigid connecting pipe 702. A pressure plate 703 with an annular seal is provided in the liquid storage tank 701. The pressure plate 703 is connected to the bottom of the mounting plate 901 through a push rod 704 provided on the top thereof. A return spring 606 is provided between the top of the push plate 603 and the top surface of the housing 601; wherein the push rod 704 penetrates the top of the liquid storage tank 701 and is slidably connected to the liquid storage tank 701. When the pressure plate 703 moves downward, it squeezes the hydraulic medium to drive the push plate 603 to move downward, and the return spring 606 returns the push plate 603 to its original position after the pressure is released. The regulating component includes a rotating cap 803 rotatably arranged at one end of the shaft 802 away from the fan motor 801, teeth are arranged on the outer periphery of the rotating cap 803, a threaded rod 804 is screwed inside the rotating cap 803, a cross bar 805 is rotatably arranged at one end of the threaded rod 804 close to the fan motor 801, a telescopic rod is fixed to the other end of the threaded rod 804, the other end of the telescopic rod is fixedly connected to the water supply pipe 502, the limiting threaded rod 804 rotates, and the other end of the cross bar 805 is fixedly connected to the adjustment block 806; the other end of the bottom of the mounting plate 901 is fixedly connected to a transmission gear rod 902 meshing with the rotating cap 803.

[0029] In this embodiment, when the temperature sensor detects that the temperature on the air inlet side exceeds the threshold, the electric push rod 9 starts and pushes the mounting plate 901 downward, and the synchronous action of the mounting plate 901 triggers the linkage at both ends: The mounting plate 901 presses down the push rod 704, forcing the pressure plate 703 to compress the hydraulic medium in the liquid storage tank 701. The medium enters the top cavity of the housing 601 through the rigid connecting pipe 702, pushing the push plate 603 to overcome the resistance of the return spring 606 and move downward, driving the throttle plate 605 at the end of the push rod 604 to move downward, expanding the cross-sectional area of ​​the liquid outlet channel between it and the annular protrusion 602, and increasing the water flow rate; The transmission gear rod 902 at the other end of the mounting plate 901 drives the rotating cap 803 to rotate, and the threaded rod 804 cannot rotate due to the restraint of the stopper 10, forcing the adjustment block 806 to slide along the inner cavity of the hollow shaft 802, and the support rod 808 is meshed with the rack 810 through the gear 809, so that the blade 811 increases its inclination angle and expands outward, thereby increasing the air volume; When the temperature drops below the threshold, the electric push rod 9 retracts, the pressure plate 703 is reset under the action of the reset spring 606, the hydraulic medium flows back to the liquid storage tank 701, and the throttle plate 605 moves up to narrow the liquid outlet channel; at the same time, the regulating component moves in the reverse direction, the inclination angle of the blade 811 returns to the initial state, and the system enters the low power consumption mode.

[0030] Preferably, a limiter 10 is fixedly sleeved on the water supply pipe 502, and the other end of the limiter 10 is slidably sleeved on the transmission gear rod 902 to limit the vertical movement of the transmission gear rod 902 and improve the meshing effect between the transmission gear rod 902 and the rotating cap 803. In addition, the transmission gear rod 902 is always meshed with the rotating cap 803 after moving and resetting.

[0031] Preferably, a multi-stage flow guiding structure is provided in the water distributor 4, including: A conical nozzle 402 connected to the water inlet pipe 401 is arranged at the top center of the water distributor 4; The guide plate 403 arranged transversely has a triangular prism-shaped guide surface with a central bulge on its top, forming a gradient distribution with high in the middle and low on both sides; The bottom of the guide plate 403 is divided into three independent guide chambers by two groups of vertical vertical plates 405; Three groups of water flow holes 404 are arranged at intervals along the length direction of the guide plate 403, respectively corresponding to each guide cavity vertically; The water flows through the nozzle 402 and then is evenly distributed along the guide surface. It enters the corresponding guide cavity through the water flow hole 404 to achieve three-level rectification and then is discharged from the water outlet hole 406. When water flows into the water distributor 4 from the water inlet pipe 401, it first diffuses through the nozzle 402 in the center of the top to form an umbrella-shaped water curtain that evenly covers the triangular prism-shaped guide surface of the guide plate 403 below. Since the guide surface is high in the middle and low on both sides, the water naturally flows to the left and right sides along the slope to avoid water accumulation in the central area. Subsequently, the water flows through three groups of water flow holes 404 spaced apart on the guide plate 403, and flows vertically into three independent guide chambers separated by vertical vertical plates 405 at the bottom. Finally, the water after diversion is evenly discharged from the water outlet holes 406 at the bottom of each guide chamber to cover the top of the wet curtain 3, thereby improving the wetting effect of the wet curtain 3.
