DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0018] Please refer to Figs. 1 to 3This utility model provides a technical solution: a positive pressure booster for small and medium-sized cabs of agricultural and engineering machinery, including a booster housing 1, an inlet 3 on one side of the booster housing 1, a filter element baffle 4 installed on one side of the booster housing 1 outside the inlet 3, a filter paper filter element 5 inside the booster housing 1, an activated carbon filter element 6 inside the booster housing 1 on one side of the filter paper filter element 5, a housing cover 7 on the top of the booster housing 1, and a fan body 8 inside the booster housing 1 on one side of the filter paper filter element 5 and the activated carbon filter element 6. Two air outlets 9 are provided on one side of the booster housing 1. The output end of the blower body 8 is matched with the air outlets 9. The output end of the blower body 8 is matched with the two air outlets 9. The filter paper filter element 5 and the activated carbon filter element 6 are matched with the input end of the blower body 8. Mounting brackets 2 are fixedly installed on the bottom of the front and back of the booster housing 1. A blower plug interface 10 is provided on one side of the booster housing 1. Several air inlets 11 are opened inside the back of the booster housing 1. The housing cover 7 is fixedly connected to the booster housing 1 by screws. The mounting brackets 2 are convenient for installation on the cab of agricultural machinery and engineering machinery.
[0019] A bolt 12 is provided on the inner side of the inlet 3. A positioning hole 13 is provided inside the booster housing 1 and on the side of the inlet 3 and the filter element baffle 4. The bolt 12 is engaged with the positioning hole 13. A Phillips handle nut 14 is installed on the outer thread of the bolt 12. The Phillips handle nut 14 is engaged with the filter element baffle 4. The bolt 12, the positioning hole 13 and the Phillips handle nut 14 are used to facilitate the installation and removal of the filter element baffle 4, so as to replace the filter paper filter element 5 and the activated carbon filter element 6.
[0020] In summary, this positive pressure booster for small and medium-sized cabs of agricultural and engineering machinery works by turning on the fan body 8. Outside air enters the booster housing 1 through the air inlet 11 and then passes through two filters: a filter paper filter element 5 and an activated carbon filter element 6. These filters adsorb dust, fine particles, and odors from the air. The filtered air then enters the fan body 8 through its input end and is delivered to the corresponding air outlet in the cab through its output end and air outlet 9. This creates a positive pressure effect inside the cab, where the pressure is higher than the outside pressure.
