DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 The present application will be described in further detail.

[0034] The embodiment of the present application discloses a building energy-saving fresh air system. Referring to Figure 1 and Figure 2 A building energy-saving fresh air system, comprising a shell 1, an air inlet assembly 2 and an air outlet assembly 3, the air inlet assembly 2 and the air outlet assembly 3 are both arranged through the shell 1. The shell 1 is provided with two opposite cover plates 4, the side of the cover plate 4 close to the shell 1 is provided with a first sound insulation pad 41, and the inner wall of the shell 1 is connected with a plurality of second sound insulation pads 5 through a connecting assembly. In the working process of the air inlet assembly 2 and the air outlet assembly 3, each first sound insulation pad 41 and second sound insulation pad 5 absorbs the noise generated when the air inlet assembly 2 and the air outlet assembly 3 work, reduces the noise when the fresh air system works, and improves the user experience.

[0035] Referring to Figure 1 and Figure 2The connecting assembly comprises a plurality of first magnets 51, each of which is arranged on the second sound insulation pad 5 uniformly, the inner wall of the shell 1 is provided with a plurality of connecting grooves 11, each of which corresponds to a first magnet 51, and each connecting groove 11 is embedded with a second magnet 111 matched with the first magnet 51. The first sound insulation pad 41 and the second sound insulation pad 5 are both made of sound-absorbing sponge.

[0036] When the worker needs to install the second sound insulation pad 5, the worker inserts each first magnet 51 on the second sound insulation pad 5 into the corresponding connecting groove 11, so that each first magnet 51 is magnetically connected with the corresponding second magnet 111, and the installation of the second sound insulation pad 5 is completed. At this time, each second sound insulation pad 5 can absorb the noise generated by the operation of the air inlet assembly 2 and the air outlet assembly 3, thereby reducing the noise generated by the operation of the fresh air system.

[0037] Referring to Figure 1 and Figure 2 , the air inlet assembly 2 and the air outlet assembly 3 each comprise a first air pipe 6 and a second air pipe 7, the end of the first air pipe 6 away from the second air pipe 7 and the end of the second air pipe 7 away from the first air pipe 6 both extend out of the shell 1. The first air pipe 6 and the second air pipe 7 are sequentially provided with a filter assembly 8 and a fan 9 along the air flow direction, that is, the first air pipe 6 corresponding to the air inlet assembly 2 extends to the outdoor, and the first air pipe 6 corresponding to the air outlet assembly 3 extends to the indoor. The rotation directions of the fans 9 in the air inlet assembly 2 and the air outlet assembly 3 are opposite to each other, so as to realize the function of circulating the air in the room.

[0038] The filter assembly 8 comprises a filter frame 81, a filter screen 82 and filter cotton 83, one side of the filter frame 81 is connected with the first air pipe 6, the other side is in abutment with the fan 9, and the filter screen 82 and the filter cotton 83 are sequentially arranged in the filter frame 81 along the air flow direction, that is, the filter cotton 83 is arranged on the side of the filter screen 82 close to the fan 9. The filter cotton 83 is made of activated carbon fiber.

[0039] When the air in the room needs to be circulated, the fans 9 in the air inlet assembly 2 and the air outlet assembly 3 are started at the same time, and the rotation directions of the fans 9 in the air inlet assembly 2 and the air outlet assembly 3 are opposite to each other. Fresh air in the outdoor enters the room through the first air pipe 6 and the second air pipe 7 of the air inlet assembly 2, and the dirty air in the room is discharged to the outdoor through the first air pipe 6 and the second air pipe 7 of the air outlet assembly 3. When the air in the outdoor passes through the filter screen 82 and the filter cotton 83, the impurities in the air are filtered and the peculiar smell in the external air is adsorbed. When the air in the room passes through the filter screen 82 and the filter cotton 83, the impurities in the air in the room are filtered and the peculiar smell in the room is adsorbed, thereby improving the cleanliness of the air in the room and the quality of the air delivered by the fresh air system.

[0040] Referring to Figure 2 and Figure 3In order to facilitate the installation of the filter frame 81 and the fan 9, the casing 1 is fixed with a positioning plate 12, and the filter frame 81 and the fan 9 are in abutment with the positioning plate 12. The filter frame 81 is fixed with a positioning column 811, and the positioning plate 12 is provided with a positioning groove 121, and the positioning column 811 is arranged in the positioning groove 121.

[0041] The casing 1 is provided with a clamping frame 13 for clamping the filter frame 81 and the fan 9, and the clamping frame 13 is embedded with a plurality of third magnets 131, and the filter frame 81 and the fan 9 are embedded with fourth magnets 132, and each third magnet 131 corresponds to a fourth magnet 132.

[0042] The worker puts the filter frame 81 and the fan 9 into the casing 1, so that the filter frame 81 and the fan 9 are in abutment with the positioning plate 12, and at the same time the positioning column 811 on the filter frame 81 is inserted into the positioning groove 121 to determine the position of the filter frame 81, thereby improving the positional accuracy between the filter frame 81 and the fan 9. The worker then clamps the filter frame 81 and the fan 9 using the clamping frame 13, so that the third magnets 131 are magnetically attracted to the corresponding fourth magnets 132, and the clamping frame 13 is fixed. At this time, the fan 9 and the filter frame 81 are positioned under the limiting action of the clamping frame 13, thereby further improving the positional accuracy between the fan 9 and the filter frame 81, so that the fan 9 and the filter assembly 8 can work more stably subsequently.

[0043] Referring to Figure 4 and Figure 5 The cover plate 4 is fixed with a fixed plate 42, and the casing 1 is provided with a first fixed groove 14, and the fixed plate 42 is arranged in the first fixed groove 14.

One end of the spring 152 is fixed with the fixed block 151, and the other end is fixed with the groove bottom of the second fixed groove 15, and the fixed plate 42 is provided with a third fixed groove 421, and the fixed plate 42 extends into the third fixed groove 421.

[0044] In order to facilitate the disassembly of the cover plate 4, the casing 1 is provided with a disassembly groove 16 which is in communication with the second fixed groove 15, and the disassembly groove 16 is provided with a pull rope 161 which extends into the second fixed groove 15 and is fixed with the fixed block 151, and the end of the pull rope 161 away from the fixed block 151 is connected with a pull ring 162.

[0045] When the cover plate 4 needs to be fixed, the worker turns the cover plate 4 towards the direction of the shell 1, so that the fixing plate 42 is inserted into the first fixing groove 14. When the fixing plate 42 is in contact with the fixing block 151, the fixing plate 42 controls the fixing block 151 to retract into the second fixing groove 15, so that the spring 152 is in a compressed state. When the fixing block 151 is opposite to the third fixing groove 421, the fixing block 151 is clamped into the third fixing groove 421 under the elastic force of the spring 152, so as to limit the fixing plate 42. At this time, the fixing of the cover plate 4 is completed.

[0046] When the air inlet assembly 2 and the air outlet assembly 3 in the shell 1 need to be overhauled, the worker pulls the pull ring 162 away from the shell 1, and the pull ring 162 moves the pull rope 161 and the fixing block 151 in sequence. After the fixing block 151 is separated from the third fixing groove 421, the worker can turn the cover plate 4 away from the shell 1. After the fixing plate 42 is separated from the first fixing groove 14, the cover plate 4 is disassembled, so that the worker can overhaul the air inlet assembly 2 and the air outlet assembly 3.
