Abstract
Description
Technical Field
[0001] The utility model relates to the field of ventilation, in particular to a basement ventilation and smoke exhaust device. Background Art
[0002] As a relatively closed space, the ventilation and smoke exhaust problem of the basement has always been an important challenge. The existing ventilation and smoke exhaust devices in the basement often have problems such as high noise, low smoke exhaust efficiency, and inconvenient installation. The noise problem not only affects the living environment, but also may cause inconvenience to the life and work of residents. Low smoke exhaust efficiency may lead to poor air quality in the basement and even safety hazards. At the same time, the inconvenience during the installation process will also increase the cost of use and the difficulty of maintenance. Utility Model Content
[0003] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0004] A basement ventilation and smoke exhaust device comprises a base, a fan is arranged inside the base, a rectangular air duct is connected to the top of the fan, the rectangular air duct is hung on the basement roof and connected to the outside of the basement; the base is a box body, a sound insulation cotton layer is arranged on the inside of the box body, and a plurality of staggered sound insulation panels are arranged at the air inlet of the fan.
[0005] Furthermore, a sealing groove is provided at the connection of the air duct, and a sealant is coated in the sealing groove.
[0006] Furthermore, the bottom of the base is provided with adjustable feet.
[0007] Furthermore, a rain cover is provided at the outlet of the rectangular air duct.
[0008] Furthermore, a filter screen is provided at the air inlet of the fan.
[0009] Furthermore, a control panel is arranged on the side of the base.
[0010] The beneficial effects of the utility model are:
[0011] By arranging a sound insulation cotton layer inside the base box and arranging a plurality of staggered sound insulation boards at the air inlet of the fan, the utility model significantly reduces the noise during the operation of the ventilation and smoke exhaust device and improves the comfort of the living environment.
[0012] By optimizing the design of the fan and the air duct, the utility model improves the smoke exhaust efficiency and ensures that the basement air can be quickly and effectively updated, thereby improving the air quality of the basement and reducing safety hazards. The air duct connection is provided with a sealing groove and sealant to ensure the sealing of the connection and prevent air leakage and noise leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0018] A basement ventilation and smoke exhaust device comprises a base 1, a fan 2 is arranged inside the base, a rectangular air duct 3 is connected to the top of the fan 2, the rectangular air duct 3 is hoisted on the basement roof and connected to the outside of the basement; the base 1 is a box body, a sound insulation cotton layer 4 is arranged on the inside of the box body, and a plurality of staggered sound insulation boards 5 are arranged at the air inlet of the fan 2.
[0019] The connection of the air duct 3 is provided with a sealing groove 6, and a sealant is applied in the sealing groove 6. An adjustable foot 7 is provided at the bottom of the base 1. A rain cover 8 is provided at the outlet of the rectangular air duct 3. A filter screen is provided at the air inlet of the fan 2. A control panel 9 is provided on the side of the base 1.
[0020] Working principle: When the user needs to start the device through the control panel, the fan will start working. The control panel can set the fan operation mode, such as ventilation mode or smoke exhaust mode. In ventilation mode, the fan inhales the air in the basement through the air inlet. The filter at the air inlet will prevent dust and debris from entering the fan to ensure the cleanliness of the air. After being processed by the fan, the inhaled air is discharged to the outside of the basement through the rectangular air duct to achieve ventilation. In smoke exhaust mode, the fan will run at a higher power to quickly exhaust the smoke and harmful gases in the basement.
[0021] During the entire process, the device effectively reduces noise generation through sound insulation cotton layers and sound insulation panels, providing a quiet operating environment.
[0022] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. Based on the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
