Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fabric air permeability detection, and particularly relates to an air blowing structure for fabric air permeability detection. Background Art
[0002] There are existing equipment for fabric air permeability detection, in which the blowing structure is an important component of the equipment, which provides gas for detection to the fabric. Common blowing equipment includes structures such as fans or air pumps. When comparing the air permeability of different types of fabrics, equal amounts of gas can be used to blow them onto different fabrics respectively, and then the amount of gas passing through the fabric is detected. However, when the gas is blown onto the fabric, the dust in the air will be blown onto the fabric, causing the dust to adhere to the fabric, making the fabric relatively dirty after detection. In order to avoid this situation, the most common solution is to use a filtering structure, such as a common dust filter, which is set at the air inlet of the blowing equipment. It is used to filter the air in advance when the fan or air pump is exhausting air, so that dust cannot be blown onto the fabric.
[0003] The above-mentioned method of testing the air permeability of fabrics is inevitably related to the gas flow rate during the test. For the same fabric, when the gas is blown to the fabric, the greater the flow rate, the more gas will pass through the fabric. However, although the dust filter can solve the problem of dust adhering to the fabric, as the fan or air pump runs, dust will adhere to the filter and accumulate more and more, causing the mesh of the filter to be gradually blocked by dust, causing the airflow generated by the fan or air pump to become weaker and weaker. Therefore, when testing the air permeability of multiple fabrics, the fabrics tested in the early stage are subjected to a higher gas flow rate. When testing the later fabrics, the filter mesh is blocked, the air intake effect is limited, and the gas flow rate of the later fabrics is smaller, which makes the comparison data detected inaccurate. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the utility model provides an air blowing structure for fabric air permeability detection. An air bag is provided to temporarily store gas, so that the gas generated by the fan is not blown directly onto the fabric, but is first stored in the air bag, and then the air bag is squeezed by an electric push rod to blow the gas as a whole onto the fabric on the operating table. Therefore, when blowing air onto the fabric, the gas flow rate will not be affected by the air intake of the fan, thus avoiding the phenomenon that the filter mesh is blocked and the gas flow rate is weakened. Furthermore, when comparing the air permeability of multiple fabrics, the gas flow rates to which the fabrics are respectively subjected are the same, so that the detected comparative data is more accurate.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A blowing structure for fabric air permeability detection comprises an operating table, an air outlet is opened on the operating table, a wind hood is fixedly connected to the top of the inner cavity of the operating table, the top opening of the wind hood corresponds to the air outlet of the operating table, a mounting plate is fixedly connected to the top of the inner cavity of the operating table, an air bag is fixedly installed on the right side of the mounting plate, an electric push rod is fixedly connected to the right side of the inner cavity of the operating table, the telescopic end of the electric push rod is fixedly connected to the air bag through a push plate, an air outlet pipe is connected to the side of the air bag, an air valve is installed on the air outlet pipe, the air outlet pipe is connected to the wind hood through a flow meter, a fan is fixedly connected to the bottom of the inner cavity of the operating table, the air outlet of the fan is connected to the air bag through an air inlet pipe, and a filter is installed at the air inlet of the fan.
[0007] Furthermore, a protective net is provided at the opening of the operating table.
[0008] Furthermore, the air intake pipe is a rubber hose, and a one-way valve is installed on the air intake pipe.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. By setting up an air bag to temporarily store gas, the gas generated by the fan is not blown directly to the fabric, but is first stored in the air bag, and then the electric push rod squeezes the air bag to blow the gas to the fabric on the operating table. When blowing air to the fabric, the flow rate of the gas will not be affected by the air intake of the fan, avoiding the blockage of the filter mesh and the phenomenon of weakening the gas flow rate. In addition, when comparing the air permeability of multiple fabrics, the gas flow rates received by the fabrics are the same, making the detected comparison data more accurate.
[0011] 2. A protective net is used to prevent fabrics from falling into the operating table from the air outlet of the operating table. A rubber hose is used as an air inlet pipe to facilitate the movement of the air inlet pipe during the compression and reset process of the airbag. A one-way valve is used to prevent the gas in the airbag from being discharged from the air inlet pipe when the airbag is compressed. BRIEF DESCRIPTION OF THE DRAWINGS

After the air is filtered through the filter, it is transported to the air bag 4 from the air inlet pipe 11 by the fan 10 until a certain amount of gas is stored in the air bag 4. During the test, the fabric is flattened and fixed at the air outlet on the operating table 1. Open the air valve 8, start the electric push rod 5 to drive the push plate 6 to move to the left at a constant speed, the push plate 6 squeezes the air bag 4, the gas in the air bag 4 enters the wind hood 2 from the air outlet pipe 7, and blows upward to the fabric, observe the gas content through the flow meter 9, when it reaches the specified amount, close the electric push rod 5, and then the detection structure on the operating table 1 detects the content of gas passing through the fabric in this process.
