It includes a housing, an air intake assembly, and an exhaust assembly. The air intake assembly consists of a first air intake pipe, a heating branch, a cooling branch, and a first air outlet pipe. Both the heating and cooling branches are located on the first air intake pipe. The heating branch has a heating chamber and several fans for drawing gas from the first air intake pipe into the heating chamber and for pressing gas from the heating chamber into the first air outlet pipe. The cooling branch has a cooling chamber and several fans for drawing gas from the first air intake pipe into the cooling chamber and for pressing gas from the cooling chamber into the first air outlet pipe. The operation of each branch is controlled by the fans, enabling heating / cooling of the outside air as needed to control the temperature inside the mine and effectively improve the comfort of the working environment.

[0003] Mine ventilation systems are specialized equipment used in underground mining environments to improve air quality, ensure the safety of workers, and maintain normal mining operations by introducing fresh air, expelling toxic and harmful gases (such as methane, dust, and carbon monoxide), and regulating temperature and humidity. However, most existing mine ventilation systems lack effective foreign object blocking structures, making it easy for foreign objects to adhere to the internal air intake components, affecting ventilation efficiency and even causing equipment failure. Furthermore, the filter cleaning methods are often limited or inconvenient, making quick cleaning difficult and affecting the continuity of ventilation work, thus reducing ventilation effectiveness.

An insert plate 14 is inserted into the inner wall of the mounting bracket 13, and the side of the insert plate 14 closest to the filter frame 4 is fixedly connected to the filter frame 4. In this embodiment, by setting the mounting bracket 13 and the insert plate 14, the filter frame 4 can be quickly installed or removed by inserting the insert plate 14 into the mounting bracket 13, which facilitates the regular replacement and cleaning of the filter screen 5, reduces maintenance downtime, and improves the ease of use of the device.
