[0001] The utility model relates to the technical field of fans, in particular to a two-way flow fresh fan for air conditioning, heating and ventilation. Background Art

[0002] The two-way flow fresh air fan has an independent exhaust and air supply system. The polluted air is discharged to the outside through the exhaust port, exhaust duct and exhaust fan, and the fresh air outside is sent into the room through the supply fan, air supply duct and air supply port. When the air conditioner blows warm air into the room, the two-way flow fresh air fan is used to exchange the indoor and outdoor air to keep the indoor air fresh. At this time, a two-way flow fresh air fan for air conditioning and HVAC ventilation will be used.

[0003] The long-term use of the two-way flow fresh air fan for air conditioning and HVAC ventilation requires the replacement of the activated carbon plate to maintain the filtering effect of the two-way flow fresh air fan. At the same time, the user needs to check the fan regularly to keep it working normally. Usually when replacing the activated carbon plate or inspecting the fan, the surface of the two-way flow fresh air fan is usually connected to the shell and the baffle by multiple bolts, which increases the time for the user to remove the baffle. While increasing the disassembly time, the efficiency of the inspection is reduced. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, since the surface of the two-way flow fresh air fan is usually connected to the shell and the baffle by multiple bolts, the time for the user to remove the baffle is increased. While increasing the disassembly time, the efficiency of inspection is reduced. The utility model proposes a two-way flow fresh air fan for air conditioning and HVAC ventilation.

DETAILED DESCRIPTION

[0021] 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.

[0022] The following is combined with Figure 1-4 To further explain this application in detail,

[0023] The present application discloses a bidirectional flow fresh air fan for air conditioning and heating ventilation. Figure 1 and Figure 2 A two-way flow fresh air fan for air conditioning and heating ventilation, comprising a shell 1, a fan 2 is fixedly installed on the inner wall of the shell 1, a duct 3 is fixedly connected to the surface of the shell 1, a partition 4 is fixedly installed on the inner wall of the shell 1, and a disassembly mechanism 5 is arranged on the surface of the shell 1;

[0024] The disassembly mechanism 5 includes a fixing groove 501, which is opened at the top of the shell 1. A damping telescopic rod 502 is fixedly installed on the inner wall of the fixing groove 501. A baffle 503 is movably connected to the top of the damping telescopic rod 502. A positioning rod 504 is threadedly connected to the inner wall of the baffle 503. The surface of the positioning rod 504 is threadedly connected to the inner wall of the damping telescopic rod 502.

[0025] Reference Figure 1 and Figure 3 A connecting block 6 is fixedly installed at the bottom of the baffle 503, and a connecting groove 7 is opened at the top of the shell 1. The connecting block 6 is made of rubber, and the surface of the connecting block 6 is in close contact with the inner wall of the connecting groove 7. The sliding connection between the connecting block 6 and the connecting groove 7 can increase the contact area between the baffle 503 and the shell 1, and the sealing between the baffle 503 and the shell 1 can be increased by the connecting block 6 made of rubber;

[0026] Reference Figure 1 The surface of the baffle 503 is fixedly mounted with an extension plate 8, and the surface of the extension plate 8 is slidably connected to the surface of the housing 1. Through the sliding connection between the extension plate 8 and the housing 1, the baffle 503 can wrap the housing 1, further strengthening the sealing between the housing 1 and the baffle 503;

[0027] Reference Figure 4 The surface of the partition plate 4 and the surface of the shell 1 are fixedly installed with a limit block 9, and the inner side of the limit block 9 is slidably connected with an activated carbon plate. By setting the limit block 9, the position of the activated carbon plate can be fixed, and the stability of the activated carbon plate during operation is increased;

[0028] Reference Figure 1 A fixing rod 10 is fixedly installed on one side of the shell 1, and a rotating block 11 is rotatably connected to the inner wall of the extension plate 8. The inner side of the rotating block 11 is movably connected to the surface of the fixing rod 10. Through the movably connected fixed rod 10 and rotating block 11, the moving distance of the baffle 503 can be limited, so that the baffle 503 is prevented from moving when the baffle 503 is in contact with the shell 1;

[0029] Reference Figure 1 A power supply is fixedly installed on one side of the housing 1, and the output end of the power supply is electrically connected to the fan 2. A protective box 12 is fixedly installed on the surface of the housing 1, and the power supply is fixedly installed in the inner cavity of the protective box 12. By setting the protective box 12, the power supply on one side of the housing 1 can be protected to prevent the power supply from colliding with the outside world, causing damage to the power supply, and increasing the service life of the power supply;

[0030] Reference Figure 1 The surface of the protective box 12 is provided with ventilation holes 13, and the inner wall of the ventilation holes 13 is fixedly installed with a dustproof net 14. By setting the ventilation holes 13 and the dustproof net 14, the contact area between the power supply and the outside air can be increased through the ventilation holes 13, and the heat dissipation effect of the power supply can be increased. The dust in the air can be prevented from entering the inner cavity of the protective box 12 through the dustproof net 14, and the inner cavity of the protective box 12 can be kept clean;

[0031] Working principle: When the user needs to inspect the fan 2 or replace the activated carbon plate, the user pulls up the baffle 503 to separate the baffle 503 from the housing 1, and supports the baffle 503 through the damping telescopic rod 502. The damping force of the damping telescopic rod 502 prevents the baffle 503 from moving downward due to the gravity of the baffle 503, so that the fan 2 and the activated carbon plate in the inner cavity of the housing 1 are exposed to the user's field of vision, which is convenient for the user to inspect the fan 2 or replace the activated carbon plate. When the replacement, inspection or follow-up replacement is completed, the user only needs to push the baffle 503 downward to make the baffle 503 contact with the shell 1 again to complete the sealing, which reduces the user's disassembly time and increases the user's inspection or replacement efficiency. When it is found that the motor is damaged and needs maintenance, the user rotates the positioning rod 504 to cancel the threaded connection between the positioning rod 504 and the damping telescopic rod 502. The user moves the baffle 503 upward to disengage the baffle 503 from the damping telescopic rod 502, thereby increasing the user's maintenance space.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
