DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A dust reduction ventilation device for an electric machine room, comprising:

[0029] Computer room 1;

[0030] A ventilation mechanism is provided on the machine room 1; the ventilation mechanism includes a fan 3 and an air outlet 5, the air outlet 5 is installed on the inner top of the machine room 1, the fan 3 is installed on the outer wall of the machine room 1, the air outlet end of the fan 3 is connected to the air outlet 5 through a pipeline, and the fan 3 is provided as an ion fan 3; the air outlet end of the fan 3 is fixedly connected to an air outlet pipe 4, and the end of the air outlet pipe 4 is connected to the air outlet 5. The air inlet end of the fan 3 is fixedly connected to an air inlet pipe 8, and the end of the air inlet pipe 8 is connected to the top of the filter cartridge 9. A door panel 2 is provided on one side of the machine room 1, and an exhaust port 6 is provided on the upper end of one side of the machine room 1, an exhaust fan 7 is installed in the exhaust port 6, and a filter is also installed in the exhaust port 6.

[0031] A filtering mechanism is arranged on the air inlet side of the fan 3; the filtering mechanism includes a filter cartridge 9, a cartridge cover 10 and a filter element 12. The cartridge cover 10 is threadedly mounted on the lower end of the filter cartridge 9. A sleeve 11 is integrally formed on the cartridge cover 10. The filter element 12 is plugged into the inner cavity of the sleeve 11.

[0032] By setting a fan 3 structure including a fan 3 and an air outlet 5 on the machine room 1, the air outlet pipe 4 of the fan 3 is connected to the air outlet 5 at the top of the machine room 1, and the air inlet pipe 8 of the fan 3 is connected to the filtering mechanism, and the filtering mechanism includes a filter cartridge 9, a cartridge cover 10 and a filter element 12. In actual use, the fan 3 works to extract external air and transmits it to the machine room 1 through the pipeline after passing through the filtering mechanism, and cooperates with the exhaust port 6 to form a circulating ventilation, which can take away the heat in the machine room 1 and realize the ventilation and heat dissipation of the equipment in the machine room 1. At the same time, the setting of the filtering mechanism can filter the air before it enters the machine room 1, so as to prevent large particles of impurities, dust, flying catkins, etc. from entering the machine room 1, thereby providing a good working environment for the equipment in the machine room 1;

[0033] At the same time, since there are many cabinets and cables installed in the machine room 1, static electricity is easily generated. Under the action of static electricity, the dust in the machine room 1 is easily attached to the equipment. The present application sets the fan 3 as an ion fan 3. When the fan 3 is working, the high-voltage electric field inside it ionizes the air molecules to generate a large number of positive and negative ions. These ions are accelerated under the action of the electric field force to form a high-speed ion airflow. When the ion airflow contacts the surface of a charged object, the positive and negative ions will neutralize the electrostatic charge on the surface of the object, thereby eliminating static electricity, making it difficult for the dust in the machine room 1 to adhere to the equipment, thereby achieving the dust reduction effect in the machine room 1. After the machine room 1 is cleaned once, it is easier to keep it clean afterwards.

[0034] In general, the device has a simple structure and is easy to use. It can ensure that the machine room 1 has a good ventilation environment and can also play a dust reduction role, preventing large particles of dust and catkins from entering during ventilation. It can not only ensure the ventilation and heat dissipation of the equipment in the machine room 1, but also prevent excessive dust in the machine room 1 from affecting the operation of the equipment.

[0037] By setting an external thread section 13 on the outer wall of the cylinder cover 10 and an internal thread section 14 on the inner wall of the lower end of the filter cylinder 9, the filter mechanism can be quickly and conveniently assembled and disassembled by rotating the cylinder cover 10, so as to facilitate the replacement and cleaning of the filter element 12 inside the sleeve 11.

[0038] Also, see Figure 3-4 In order to improve the sealing performance of the filter mechanism and prevent air from entering the fan 3 through the gap, the present application makes the following design:

The upper inner wall of the filter cartridge 9 is symmetrically provided with connecting plates 15, and both sides of the upper sealing ring 16 are symmetrically provided with connecting rods 17. Two groups of connecting rods 17 are respectively slidably inserted into the two groups of connecting plates 15. A compression spring 18 is sleeved on the connecting rod 17 between the upper sealing ring 16 and the connecting plate 15, and a limit block is provided at the upper end of the connecting rod 17.

[0040] By setting an upper sealing ring 16 and a lower sealing ring 19, the lower sealing ring 19 is set at the lower end of the inner wall of the sleeve 11, and the connecting rods 17 on both sides of the upper sealing ring 16 are slidably inserted into the connecting plate 15 on the inner wall of the filter cartridge 9, and the compression spring 18 is sleeved on the connecting rod 17.
