DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 A natural clean air cooling fan case in the present embodiment includes a case body 1, on which a preheating mechanism 2 for preventing indoor condensation is arranged, so that the external cold air enters the room for cooling while avoiding condensation due to excessive temperature difference, and an air inlet mechanism 3 for filtering the air entering the interior of the case body 1, so as to purify the cold air entering the room and avoid indoor pollution, and a fan body 4 is fixed to the inner bottom wall of the case body 1, and a case door 5 is hinged on the front of the case body 1 through a hinge shaft, and a handle 6 is fixed on the front of the case door 5, and the case door 5 can be opened by the handle 6, so as to facilitate the replacement or maintenance of the components inside the case body 1, and a control panel 7 is fixed on the front of the case door 5, and an intelligent control system is arranged indoors, and the intelligent control system includes an outdoor temperature and humidity sensor, an indoor temperature and humidity sensor, a pressure difference sensor, a condensation sensor, a water intrusion sensor, a smoke sensor, a fire protection system, a monitoring system and a control mainboard, which are used to monitor the indoor and outdoor environment.

[0024] There are two cabinet doors 5 , which are symmetrically distributed about the central axis of the chassis body 1 . The double-opening cabinet doors 5 can reduce the space required to open the cabinet doors 5 .

[0025] See also Figure 3-4 In order to allow the outside cold air to enter the room for cooling while avoiding condensation due to excessive temperature difference, the preheating mechanism 2 in this embodiment includes a mounting hole 201 opened on the upper surface of the chassis body 1, and a connecting plate 202 is fixed to the inner side of the mounting hole 201. A connecting hole 203 is opened on the upper surface of the connecting plate 202, so that the chassis body 1 is connected with the room so that the indoor air can enter the chassis body 1, and a closing component is arranged on the chassis body 1.

[0026] In this example, there are four mounting holes 201, which are symmetrically distributed about the central axis of the chassis body 1. The number of connecting holes 203 on each connecting plate 202 is no less than two, and they are evenly distributed on the upper surface of the connecting plate 202, so that the indoor air is more evenly distributed when entering the chassis body 1, thereby improving the effect of mixing and preheating with the external cold air.

[0027] It should be noted that the sealing component includes a motor 204 fixed to the inner top wall of the chassis body 1. When the indoor intelligent control system detects that the temperature difference between indoor and outdoor is too large and condensation will occur, the motor 204 is turned on. The output shaft of the motor 204 passes through and extends to the upper side of the chassis body 1, and a rotating plate 205 is fixed. The output shaft of the motor 204 drives the rotating plate 205 to rotate. A baffle 206 is fixed to the outer side of the rotating plate 205. The rotating plate 205 drives the baffle 206 to rotate. A sealing gasket 207 is fixed to the lower surface of the baffle 206. The baffle 206 drives the sealing gasket 207 to move, thereby removing the baffle 206 and the sealing gasket 207 from the connecting plate 202. The number of baffles 206 is equal to the number of connecting plates 202, and the positions correspond one to one. The outer diameter of the baffle 206 is larger than the outer diameter of the connecting plate 202, so as to open or close the connecting hole 203 at the same time.

[0028] See also Figure 5 In order to purify the cold air entering the room and avoid indoor pollution, the air inlet mechanism 3 in this embodiment includes a connecting flange 301 connected to the right side of the chassis body 1, and the right side of the connecting flange 301 is connected to a fusible fire damper 302. When the outside air temperature is greater than 70°C, the fusible fire damper 302 is melted and closed to block the indoor and outdoor air circulation to prevent the fire from spreading to the room. The right side of the fusible fire damper 302 is connected to an air inlet pipe 303, and the wind force generated by the fan body 4 draws the outside air into the air inlet pipe 303. An isolation net 304 is fixed on the inner side of the air inlet pipe 303. The isolation net 304 can block insects, catkins, leaves, birds, etc. to prevent them from entering the chassis body 1. A filter component is arranged on the chassis body 1.

[0029] In this example, the filter assembly includes a first rail fixed on the left and right inner walls of the chassis body 1, and the inner sides of the two first rails are plugged with filter screens 305, which filter out larger dust and impurities. The left and right inner walls of the chassis body 1 are fixed with second rails, and the inner sides of the two second rails are plugged with filter plates 306. The filter plates 306 perform secondary filtration to filter out smaller dust. A mounting plate is fixed between the left and right inner walls of the chassis body 1, and a filter bag 307 is fixed on the inner side of the mounting plate. The filter bag 307 filters dust in the air. The first rail, the second rail and the mounting plate can facilitate the disassembly and replacement of the filter screen 305, the filter plate 306 and the filter bag 307.

[0030] The working principle of the above embodiment is:

[0031] (1) First, turn on the fan body 4. The wind force generated by the fan body 4 draws the outside air into the air inlet pipe 303. The isolation net 304 can block insects, catkins, leaves, birds, etc., and prevent them from entering the chassis body 1. After the air enters the air inlet pipe 303, it enters the chassis body 1 through the connecting flange 301. The fan body 4 is located at the bottom of the chassis body 1. The air flows downward and passes through the filter net 305, the filter plate 306, and the filter bag 307 in sequence. The filter net 305 filters out larger dust and impurities. The filter plate 306 performs secondary filtration to filter out smaller dust. The filter bag 307 filters the dust in the air. After the filtration is completed, the gas is drawn into the fan body 4 and enters the room through the air outlet.

[0032] (2) When the indoor intelligent control system detects that the temperature difference between indoor and outdoor is too large, condensation will occur. At this time, the motor 204 is turned on, and the output shaft of the motor 204 drives the rotating plate 205 to rotate, and the rotating plate 205 drives the baffle 206 to rotate, and the baffle 206 drives the sealing gasket 207 to move, thereby removing the baffle 206 and the sealing gasket 207 from the connecting plate 202, so that the outside cold air enters the chassis body 1 from the connecting flange 301, and the indoor air can also enter the chassis body 1 from the connecting hole 203, so that the outside cold air is mixed with the indoor air in advance, and the outside cold air is preheated, thereby reducing the temperature difference between the cold air and the indoor air and avoiding condensation.
