[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to the attached Figure 1-7 , a fresh air ventilator housing, which is integrally rectangular, includes a housing 1. Outdoor fresh air inlets, exhaust outlets, indoor return air outlets, and air supply outlets are respectively provided at both ends of the housing 1. Inspection openings 2 penetrating through the housing 1 are provided on both sides of the housing 1, and the two inspection openings 2 are staggered. When performing inspections on the interior of the housing 1 through different inspection openings 2, a larger inspection range can be achieved, so as to improve the flexibility and coverage of maintenance. Push-pull inspection plates 3 are provided on both sides of the housing 1 to cooperate with the inspection openings 2 to open or close the inspection openings 2. Pulling the inspection plate 3 to open the inspection opening 2 can quickly perform inspections on the interior of the housing 1 without disassembling the entire machine, and the maintenance efficiency is high.

[0029] In this embodiment, tracks 4 are provided on both sides of the housing 1. The tracks 4 are horizontally laid. The tracks 4 include paired limiting plates. Sliding grooves 41 for the inspection plate 3 to slide are provided on the opposite surfaces of the paired limiting plates. The paired limiting plates are respectively arranged on the upper and lower sides of the inspection opening 2. The inspection plate 3 slides along the sliding groove 41 to open or close the inspection opening 2, and the sliding groove 41 can limit the inspection plate 3 to prevent the inspection plate 3 from shaking randomly.

[0030] In this embodiment, a push-pull plate 31 is provided on the side of the inspection plate 3 facing away from the housing 1, and it is more convenient to push and pull the inspection plate 3 through the push-pull plate 31.

[0031] In this embodiment, the push-pull plate 31 is arranged at one end of the inspection plate 3. A flat plate 32 is provided on the side facing the inspection plate 3. A slope 33 is provided on the side of the flat plate 32 away from the inspection plate 3. A first pressing strip 42 and a second pressing strip 43 are arranged between the paired limiting plates. The first pressing strip 42 and the second pressing strip 43 are respectively arranged on the left and right sides of the inspection opening 2 to cooperate with the flat plate 32 and the inspection plate 3 respectively. When the inspection plate 3 is pushed to the inspection opening 2 through the push-pull plate 31, the first pressing strip 42 presses on the flat plate 32, and the second pressing strip 43 presses on the inspection plate 3, so that the inspection plate 3 seals the inspection opening 2, preventing the gas in the housing 1 from flowing out through the inspection opening 2.

[0032] In this embodiment, an arc-shaped first pressing plate 44 is provided on the side of the first pressing strip 42 facing the housing 1. An arc-shaped first groove 34 is formed on the flat plate 32 for cooperating with the first pressing plate 44. An arc-shaped second pressing plate 45 is provided on the side of the second pressing strip 43 facing the housing 1. An arc-shaped second groove 35 is formed on the inspection plate 3 for cooperating with the second pressing plate 45. When the inspection plate 3 seals the inspection opening 2, the first pressing plate 44 will enter the first groove 34, and the second pressing plate 45 will enter the second groove 35, so as to increase the friction between the inspection plate 3 and the housing 1 and the track 4 during sealing, prevent the inspection plate 3 from moving when the air in the housing 1 flows, avoid its accidental movement, thereby ensuring the tightness of the inspection opening 2 and effectively preventing air leakage.

[0033] In this embodiment, a sealing strip 5 is provided on the inner wall of the inspection opening 2. The sealing strip 5 is arranged around the inner wall of the inspection opening 2. When the inspection plate 3 seals the inspection opening 2, it will contact the sealing strip 5, which is convenient for further improving the sealing performance.

[0034] In this embodiment, a sealing groove 21 for cooperating with the sealing strip 5 is formed on the outside of the inspection opening 2. Ribs 22 are provided in the sealing groove 21. The ribs 22 are arranged around the outside of the inspection opening 2. Rib grooves 51 for cooperating with the ribs 22 are provided in the sealing strip 5, which improves the connection stability between the sealing strip 5 and the inspection opening 2 and avoids the separation of the sealing strip 5 from the inspection opening 2 when the inspection plate 3 is moved, affecting the subsequent sealing effect;

[0035] An extension edge 52 is provided on the inner side of the sealing strip 5. The extension edge 52 fits the inner side wall of the inspection opening 2 and completely wraps the inner side wall of the inspection opening 2, effectively protecting the maintenance personnel and avoiding the side wall of the inspection opening 2 from scratching the hands of the maintenance personnel during maintenance, improving the stability during the maintenance process.
