Description

Technical Field

[0001] This utility model relates to a sterilization device for evaporative air coolers. Background Technology

[0002] Evaporative air conditioners utilize the principle of water evaporation and heat absorption to achieve rapid cooling. Compared to traditional air conditioners, they consume less electricity and use water as a refrigerant, making them environmentally friendly and pollution-free. The water inside an evaporative air conditioner is usually recycled. After a period of use, bacteria inevitably grow due to contact with components such as the water distributor and evaporative cooling pad. These bacteria, when present in the water and then humidifying the incoming air through the evaporative cooling pad, affect the air quality output by the evaporative air conditioner. Therefore, water sterilization is necessary. For example, the utility model patent with authorization announcement number CN217303045U discloses a mobile evaporative energy-saving and environmentally friendly intelligent air conditioner that uses a sterilization lamp on a water tank for sterilization. However, this device has limited sterilization range for areas not exposed to light. Utility Model Content

A water outlet pipe assembly 30 with an internal filter screen is radially arranged on the lower side of one end of the cylinder, and a water inlet pipe assembly 40 is arranged on the lower side of the other end. An observation window 50 is radially arranged on the upper side of the other end of the cylinder. Water is introduced into the sterilization cylinder through the water inlet pipe assembly, and the water is sterilized using the waterproof sterilizing lamp (which emits ultraviolet light). The sterilized water is then discharged through the water outlet pipe assembly.

[0019] In this embodiment, in order to install the waterproof sterilization lamp, a side end cap 60 is screwed to the other end of the sterilization cylinder.

A water inlet connecting pipe 42 is connected to the water inlet pipe, and the diameter of the water inlet connecting pipe gradually decreases in a stepped manner along the axial direction. The gradual increase in the diameter of the water inlet connecting pipe along the water input direction, coupled with the fact that the diameter of the sterilization cylinder is larger than the diameter of the water inlet connecting pipe, helps to increase the residence time of water within the sterilization cylinder, thereby improving the sterilization effect.

[0026] In this embodiment, an inlet end cap 43 that is screwed onto the inlet connecting pipe is provided, and a second annular flange 44 located inside the outlet end cap is provided at the upper end of the inlet connecting pipe. A fourth sealing ring 45 that cooperates with the lower end of the inlet pipe is provided at the upper end of the second annular flange.

[0027] In this embodiment, the lower outer periphery of the water inlet connection pipe is provided with several annular anti-slip parts 46 with a cross-section in the shape of a frustum cone, so as to connect with the pipeline and lock it with a pipe clamp.

[0028] In this embodiment, the upper side of the other end of the sterilization tube is provided with an upwardly protruding tube 51. The upper end of the upwardly protruding tube is covered with a transparent plate 52, and a pressure cap 53 is screwed on to press the transparent plate to achieve a seal between the transparent plate and the upwardly protruding tube, and a fifth sealing ring 54 is provided. The middle part of the pressure cap is provided with a through hole 55 that exposes the transparent plate, thereby forming an observation window to facilitate personnel to observe the internal situation.

[0029] In this embodiment, the sterilization cylinder, the water inlet pipe assembly, and the water outlet pipe assembly are all made of plastic.

[0030] The sterilization device is installed in the evaporative air conditioner, located on the pipeline between the pump body and the water distributor. The inlet pipe assembly is the water inlet, and the outlet pipe assembly is the water outlet. After the water is sterilized by a waterproof sterilization lamp inside the sterilization cylinder, it is output through the outlet pipe assembly. Simultaneously, the filter screen installed inside the outlet pipe assembly helps to filter out large particulate impurities in the water.
