Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled evaporative ventilation and temperature-reducing cold air fans, in particular to a multifunctional cold air fan. Background Art

[0002] 1. Evaporative air coolers are commonly known as "water-cooled air conditioners" and are divided into industrial air coolers and household air coolers. Industrial air coolers are generally used in refrigeration environments such as cold storage, while household air coolers are also called "air conditioning fans", which are evaporative air conditioning devices that combine cooling and humidification.

[0003] For example 1: Chinese patent document publication number: CN201251256Y, patent number: ZL200820130930.9, discloses an air conditioning fan, the structure of the air conditioning fan is that there is a centrifugal fan wheel inside the air conditioning fan body, the wind blown out from the front blowing window, the lower part of the air conditioning fan is provided with a large water tank filled with water and a water pump inside, and the top of the air conditioning fan is provided with a small water tank on the top of the machine. The water pump continuously pumps the water in the large water tank filled with water through a water supply pipe to the high point of the small ice storage water tank on the top of the air conditioning fan, and the flowing water is then discharged from a row of water at the bottom of the small ice storage water tank on the top of the machine. The water flows through the holes to the filter screen connected below, and then flows through the filter screen to the water tank below. In order to prevent blockage and overflow, an overflow pipe is provided at the low point of the small water tank to lead to the large water tank. When in use, the centrifugal fan inside the air conditioner blows air through the filter screen, and the air is cooled by the filter screen with water circulating continuously, and then blown out from the blowing window. The air conditioner fan is named as the air conditioner fan because its appearance is similar to a miniature cabinet air conditioner, and there is a water pump in it that can cool the air in the water circulation and blow out cold air below the room temperature. It can also be installed with casters when in use, and it is popular among consumers because of its easy-to-use and mobile installation.

[0004] However, the air-conditioning fan has only one function, which is ventilation, cooling and refrigeration. It is only used in summer and is idle at other times, so its utilization rate is not high enough. There is no planting device on the small water tank on the top of the machine.

[0005] For example 2: Chinese patent document publication number: CN204787059U, patent number: ZL201520527734.5, discloses an air conditioning fan with remote control function. Although it has the fashionable remote control on / off function, it can only be idle at other times except for a period of time when the weather is hot. This situation makes consumers feel that the utilization rate of buying a household air cooler is not high and the use is not very great, which seriously affects the promotion and application of household air coolers; the top water tank is not used for related plant planting functions.

[0006] For example 3: Chinese patent document publication number: CN204787059U, patent number: ZL201520527734.5, discloses an air conditioning fan with remote control function,

[0007] Second, some consumers now want to grow bean sprouts at home and even spend money to buy small bean sprout machines. However, after using them a few times, they find them uncommon and take up too much space, so they discard them, causing unnecessary waste.

[0008] 3. Some parents, in order to let their curious children see how plants germinate and grow, either put the beans in bottles or bury the seeds in pots, which makes it inconvenient to manage and watch.

[0009] 4. There are also some people who like to grow flowers and grass at home and want to go out for a business trip or travel for a few days, but the problem of watering the flowers and plants is difficult to solve.

[0010] In summary, the above household air coolers have a single function and low utilization rate; it is inconvenient to use flower pots, bottles and other containers for home planting management and watering.
