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] See also Figure 1-4 The utility model provides an embodiment: a fresh air system with a filter element assembly that can be quickly replaced, comprising a fresh air riser 1, a filter element box 2 and a fresh air elbow 6, the fresh air riser 1 is installed at the bottom of the fresh air elbow 6, and a slot 9 is arranged at the edge position of the bottom of the fresh air elbow 6, through holes 16 are arranged at the bottom of both ends of the fresh air elbow 6, and the through holes 16 are connected to the slot 9, support block mounting slots 17 are installed at the top of both ends of the fresh air riser 1, and the top of the support block mounting slot 17 is provided with 19, the filter element box 2 is installed on the top of the support block mounting slot 17, and an activated carbon layer 3 is arranged inside the filter element box 2, an insert 11 is arranged at the edge position of the top of the fresh air riser 1, and fixed sockets 10 are arranged at both ends of the insert 11.

[0023] In this implementation:

[0024] Furthermore, L-shaped plates 5 are installed at the bottom of both ends of the fresh air curved pipe 6, and mounting holes 13 are provided inside the L-shaped plates 5. Insertion rods 15 are installed inside the mounting holes 13, and the insertion rods 15 pass through the through holes 16 and extend to the inside of the slots 9. The insertion rods 15 are inserted into the fixed sockets 10, and the insertion strips 11 are limited by the insertion rods 15 to prevent the insertion strips 11 from continuing to move, so that the fresh air riser 1 and the fresh air curved pipe 6 can be firmly installed.

[0025] Furthermore, a connecting plate 14 is installed at one end of the insertion rod 15 away from the fresh air bend pipe 6, and finger grooves are provided on the inner side of the connecting plate 14 to facilitate the staff to pull the insertion rod 15.

[0026] Furthermore, a fixing spring 12 is installed on the top of one end of the connecting plate 14 close to the L-shaped plate 5, and the end of the fixing spring 12 away from the connecting plate 14 is connected to the L-shaped plate 5. The elastic action of the fixing spring 12 causes it to pull the connecting plate 14 to move, and the connecting plate 14 drives the insertion rod 15 to move together, so that the insertion rod 15 can be inserted into the fixed socket 10.

[0027] Furthermore, support plates 7 are installed on the tops of both ends of the filter element box 2, and filter screens 4 are installed on the tops of the support plates 7, through which dust in the air can be filtered.

[0028] Furthermore, both ends of the bottom of the filter cartridge box 2 are installed with installation blocks 18. When in use, the installation blocks 18 are inserted into the interior of 19, and the filter cartridge box 2 can be supported by the support block installation slot 17, so that the filter cartridge box 2 can be installed inside the fresh air riser 1.

[0029] Furthermore, air holes 8 are evenly arranged at the bottom of the filter cartridge box 2 , and the purified gas can pass through the filter cartridge box 2 through the air holes 8 .

[0030] Working principle:

[0031] During installation, the activated carbon layer 3 can be placed inside the filter cartridge box 2, and then the filter screen 4 can be placed on the support plate 7, and then the filter screen 4 can be placed inside the filter cartridge box 2, and then the installation plug 18 at the bottom of the filter cartridge box 2 can be inserted into the inside 19, and the filter cartridge box 2 can be supported by the support block installation slot 17, and the filter cartridge box 2 can be installed inside the fresh air riser 1;

[0032] The staff can insert the insert strip 11 at the top of the fresh air riser 1 into the slot 9 provided at the bottom of the fresh air bend 6, so that the fresh air riser 1 fits tightly with the fresh air bend 6;

[0033] At this time, the fixed socket 10 on the plug strip 11 moves to a position facing the plug rod 15, and the elastic effect of the fixed spring 12 causes it to pull the connecting plate 14 to move, and the connecting plate 14 drives the plug rod 15 to move together, so that the plug rod 15 can be inserted into the fixed socket 10, and the plug strip 11 can be limited by the plug rod 15 to prevent the plug strip 11 from moving further, so that the fresh air riser 1 and the fresh air elbow 6 can be firmly installed;

[0034] During use, dust in the air can be filtered through the filter screen 4 inside the filter cartridge box 2, and the air can be purified through the activated carbon layer 3;

[0035] When the activated carbon layer 3 needs to be replaced, the staff can pull the connecting plate 14, and the connecting plate 14 drives the plug rod 15 to move, and the plug rod 15 can be taken out from the fixed plug hole 10, so that the limit of the plug rod 15 on the plug strip 11 can be released, so that the plug strip 11 can move, and then the staff can directly remove the fresh air riser 1 from the fresh air elbow 6;

[0036] The staff can take out the filter cartridge box 2 from the fresh air riser 1 and the filter screen 4 from the filter cartridge box 2 , and then replace the activated carbon layer 3 inside the filter cartridge box 2 and clean the dust attached to the filter screen 4 .

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
