[0017] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0018] refer to Figures 1 to 8 An evaporative air cooler water distribution system includes a top cover 10 and a base 20. Support columns 30 are connected to the four corners between the base and the top cover. An air inlet side plate 40 is detachably installed between the base and the top cover and between adjacent support columns on each side. A wet curtain 50 is provided on the inner side of the air inlet side plate. A water receiving tray 21 is provided in the base. A water pump 60 is installed in the water receiving tray. The output end of the water pump is connected to a water supply pipe 61. The water supply pipe is connected to a water distributor 70 installed on the top cover. Four branch pipes 80 are connected to the water distributor. Each branch pipe is connected to a water distributor 90 located above the wet curtain. Water is pumped from the drip tray into a distributor, which then distributes the water evenly into branch pipes. From there, the water is distributed to the corresponding water distributors, ensuring even distribution of water onto the evaporative cooling pads. This allows the air drawn into the evaporative air cooler to be cooled, and the fan assembly inside the evaporative air cooler then outputs the cooled air. The water on the cooling pads then collects back into the drip tray.

[0019] In this embodiment, to better achieve water distribution and deliver water to the branch pipes, the water distributor includes a main pipe 71 with a closed rear end. Fixing plates 72 for connecting to the top cover are respectively provided on both sides of the front of the main pipe. Two oblique outlet pipes 73 are respectively connected along the length direction to both sides of the main pipe and located behind the fixing plates. The water distributor is fixed to the lower end face of the top cover by the fixing plates, and the water is divided into four parts through the main pipe to deliver water into the branch pipes.

[0020] In this embodiment, the angle between the inclined outlet pipe and the main pipe is 100°~130°, so that the water in the main pipe can better enter the inclined outlet pipe.

[0021] In this embodiment, in order to better connect the water distributor to the top cover, the lower side of the cantilever end of the fixing plate is respectively fixed with a movable support seat 74, and the fixing plate is provided with bolt holes 75 passing through the support seats so as to connect with the top cover by screws.

[0022] In this embodiment, the bottom surface of the top cover is provided with an X-shaped reinforcing rib 11 to improve the strength of the top cover. The ends of the X-shaped reinforcing ribs are respectively connected to the arc-shaped protrusions 12 at the corresponding corners to facilitate the positioning and fixing of the support columns. A threaded hole 13 for the support seat is provided at one end of the X-shaped reinforcing rib to connect to the support seat on the water distributor fixing plate by screws.

[0023] In this embodiment, in order to better connect with the water supply pipe and the branch pipe, the outer periphery of the front part of the main pipe and the outer periphery of the inclined water outlet pipe are provided with a frustum-shaped annular protrusion 76, so that the water supply pipe and the branch pipe can be locked by pipe clamps or the like after being fitted onto the main pipe and the inclined water outlet pipe.

[0024] In this embodiment, in order to make the layout inside the evaporative air cooler more compact and to fix the water supply pipe, the water supply pipe extends upward along the inner side of one of the support columns and is fixed to the inner wall of the support column by a buckle.

[0025] In this embodiment, to replenish water to the water receiving pan, a water supply pipe 100 for connecting to an external tap water supply is installed on the side of the water receiving pan away from the water pump. A solenoid valve 101, which is a flow switch, is installed on the water supply pipe. A filter 110 is installed near the outlet of the water supply pipe to filter out large particles and impurities from the input water.

[0026] In this embodiment, the filter includes a vertical pipe 111 whose upper sidewall is connected to the output end of the water supply pipe. A stepped surface 112 is provided at the lower part of the inner cavity of the vertical pipe. A barrel-shaped filter screen 113, with its lower end abutting against the stepped surface, is disposed inside the vertical pipe. A pressure cap 114, abutting against the upper end of the barrel-shaped filter screen, is installed at the upper end of the vertical pipe. The water supply pipe input is water that has been filtered by the filter and then sent to a water receiving tray.

[0027] In this embodiment, the pressure cap is screwed to the upper part of the water supply pipe, and the inner side of the pressure cap is provided with an annular lower flange 115 that abuts against the upper end of the barrel-shaped filter screen; the lower part of the vertical pipe is provided with external threads.

[0028] In this embodiment, in order to better control the opening and closing of the water supply pipe, the lower end of the vertical pipe is connected to a water inlet valve 120. The water inlet valve can be the water inlet valve disclosed in the utility model patent "Water Inlet Valve Water Inlet Anti-Splash Structure" with authorization announcement number CN222479564U.

[0029] In this embodiment, the water pump is a high-leg pump, and its lower end is fixed to the bottom surface of the water receiving tray to better draw water from the tray. The high-leg pump can be the "high-leg pump" disclosed in the utility model patent with authorization announcement number CN 205779767 U, which effectively ensures the pumping effect.

[0030] In this embodiment, the water distributor is a prior art product. For example, it adopts the utility model patent "A fan-shaped water distributor specifically for evaporative air conditioners" disclosed in the authorization announcement number "CN203052924 U".

[0031] In this embodiment, in order to make the air inlet side panel detachable, the base is provided with a lower slot 22 on all four inner sides, and the top cover is provided with an upper slot 14 on all four inner sides. The upper and lower ends of the air inlet side panel are provided with an upper protruding edge 41 and a lower protruding edge 42 respectively. The height of the upper slot is greater than the height of the upper protruding edge, so that after the upper protruding edge is inserted into the upper slot, it is lifted up so that the lower protruding edge enters the lower slot. When the air inlet side panel is lowered, the air inlet side panel can be locked in the upper and lower slots.

[0032] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0033] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
