Description

A bellows for testing the breathability of clothing Technical Field

[0001] This utility model relates to the field of clothing testing technology, specifically a bellows for testing the breathability of clothing. Background Technology

[0002] Clothing is a general term for clothes, shoes, and accessories, but it mainly refers to clothing. In national standards, clothing is defined as: sewn products worn on the human body for protection and decoration, also known as clothes. Against the backdrop of constantly changing clothing production and market demand, the breathability of clothing has received increasing attention from consumers and has become one of the important indicators for measuring clothing quality. Therefore, a breathability testing bellows is needed to test it.

[0003] Currently, some existing air chambers for testing the breathability of clothing can only be fixed at one angle to test the breathability of clothing, which cannot comprehensively test the clothing from different angles. This reduces the comprehensiveness of the test and thus reduces the practicality of the equipment, failing to meet the needs of users.

[0004] Meanwhile, some existing air boxes for testing the breathability of clothing cannot filter air during intake, which makes it easy to draw in dust from the air. This dust will then be sprayed onto the clothing being tested, easily adhering to the surface of the clothing and causing blockages, which will affect the breathability and lead to inaccurate breathability testing. At the same time, the dust drawn in will also affect the testing structure. Summary of the Invention

[0005] The purpose of this invention is to provide a test chamber for the breathability of clothing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a test chamber for testing the breathability of clothing, comprising a test chamber body and a test platform fixedly connected to both sides of its inner cavity, and further comprising;

[0007] A connecting pipe is connected to the inner top surface of the detection air box body. A gas flow sensor is installed on one side of the connecting pipe. A support plate is fixedly connected to one side of the detection air box body. A fan is fixedly installed on the top of the support plate. A filter box is connected to one side of the fan through an air intake pipe. An air inlet is opened on one side of the filter box. Springs are fixedly connected to the top and bottom sides of the inner cavity of the filter box. A dust filter plate is fixedly connected to the other side of the springs. A cleaning mechanism is installed on the top of the filter box.

[0008] A horizontal pipe connected to the other side of the fan has several jet nozzles connected to its top. An adjusting rod is fixedly connected to one side of the horizontal pipe, and an adjusting mechanism is provided on one side of the inner cavity of the detection air box.

[0009] Preferably, the cleaning mechanism includes a motor fixedly connected to the top of the filter box, a transmission rod fixedly connected to the output end of the motor, and a cam fixedly connected to the bottom of the transmission rod.

[0010] Preferably, the adjustment mechanism includes a first electric telescopic rod fixedly connected to one side of the inner cavity of the detection bellows body, the telescopic end of the first electric telescopic rod being fixedly connected to a toothed plate, and the top of the toothed plate being engaged with a gear.

[0011] Preferably, a second electric telescopic rod is fixedly connected to both sides of the top of the inner cavity of the detection bellows, and a fixing plate is fixedly connected to the telescopic end of the second electric telescopic rod.

[0012] Preferably, a first slide rod is fixedly connected to one side of the inner cavity of the detection bellows, and the outer surface of the first slide rod is slidably connected to the inner surface of the toothed plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. A test chamber for testing the breathability of clothing includes a test chamber body 1. Test platforms 12 are fixedly connected to both sides of the inner cavity of the test chamber body 1. A connecting pipe 2 is fixedly connected to the inner surface of the top of the test chamber body 1, through which the ejected gas can be discharged. A gas flow sensor 3 is installed on one side of the connecting pipe 2, which can test the breathability of the discharged gas. A support plate 8 is fixedly connected to one side of the test chamber body 1, and a fan 4 is fixedly installed on the top of the support plate 8. Gas is drawn in by the fan 4 for testing. A filter box 5 is connected to one side of the fan 4 through an air intake pipe. An air inlet 7 is opened on one side of the filter box 5 for convenient air intake. Springs 18 are fixedly connected to the top and bottom sides of the inner cavity of the filter box 5, and a dust filter plate 19 is fixedly connected to the other side of the springs 18. The intake air is filtered through the dust filter plate 19 to prevent dust from being drawn in and blown onto the clothing, causing blockage. To prevent interference with air permeability testing and improve testing accuracy, the filter box 5 is equipped with a cleaning mechanism 6 on its top. The cleaning mechanism 6, in conjunction with the spring 18, allows dust adhering to the filter plate 19 to fall off and automatically clean it, preventing long-term blockage from affecting the equipment's testing. The other side of the blower 4 is connected to a horizontal pipe 14 via an air outlet pipe. Several air jets 17 are connected to the top of the horizontal pipe 14 for air jet testing. An adjusting rod 16 is fixedly connected to one side of the horizontal pipe 14, and the other side of the adjusting rod 16 is rotatably connected to one side of the inner cavity of the testing air box body 1 via a first bearing. An adjusting mechanism 9 is provided on one side of the inner cavity of the testing air box body 1. Through the cooperation of the adjusting mechanism 9 and the adjusting rod 16, the angle of the horizontal pipe 14 and the air jets 17 can be adjusted, allowing for air blowing testing of clothing at different angles. This effectively improves the comprehensiveness of the testing, enhances the equipment's testing effect, and meets the user's needs.

[0023] The cleaning mechanism 6 includes a motor 601 fixedly connected to the top of the filter box 5. The output end of the motor 601 is fixedly connected to a transmission rod 602, and the bottom of the transmission rod 602 is fixedly connected to a cam 603. Through the cleaning mechanism 6, the motor 601 drives the transmission rod 602 and the cam 603 to rotate and apply pressure to the dust filter plate 19 and the spring 18. After rotating to the reset position, the pressure is released. The elasticity of the spring 18 drives the dust filter plate 19 to shake, which can cause the dust attached to the dust filter plate 19 to fall off and automatically clean it, preventing long-term use from causing blockage and affecting the equipment's testing.

[0024] The adjustment mechanism 9 includes a first electric telescopic rod 901 fixedly connected to one side of the inner cavity of the detection airbox body 1. A toothed plate 902 is fixedly connected to the telescopic end of the first electric telescopic rod 901. A gear 903 is meshed with the top of the toothed plate 902. The inner surface of the gear 903 is fixedly connected to the outer surface of the adjustment rod 16. Through the adjustment mechanism 9, the first electric telescopic rod 901 pushes the toothed plate 902 to move, and the toothed plate 902 drives the gear 903 to rotate. The gear 903 drives the horizontal tube 14 and the air jet head 17 to adjust their angles through the adjustment rod 16. The garment can be tested by blowing air at different angles, which effectively improves the comprehensiveness of the test, improves the test effect of the equipment, and meets the needs of the user.

[0025] The top of the inner cavity of the detection bellows body 1 is fixedly connected to two sides of a second electric telescopic rod 10. The telescopic end of the second electric telescopic rod 10 is fixedly connected to a fixing plate 11. Through the second electric telescopic rod 10 and the fixing plate 11, the second electric telescopic rod 10 pushes the fixing plate 11 downward, which can fix the four sides of the garment and make it more stable during detection.

[0026] A first slide rod 15 is fixedly connected to one side of the inner cavity of the detection bellows body 1. The outer surface of the first slide rod 15 is slidably connected to the inner surface of the toothed plate 902. The first slide rod 15 can support the toothed plate 902, making it more stable when moving.

[0027] The top and bottom inner surfaces of the dust filter plate 19 are slidably connected to two sides of a second slide rod 20. One side of the second slide rod 20 is fixedly connected to one side of the inner cavity of the filter box 5, and the other side of the horizontal tube 14 is fixedly connected to a rotating rod 13. The other side of the rotating rod 13 is rotatably connected to one side of the inner cavity of the detection air box body 1 through a second bearing. The second slide rod 20 makes the movement of the dust filter plate 19 more stable and prevents the spring 18 from shifting in angle. The rotating rod 13 makes the adjustment of the horizontal tube 14 more stable.

[0028] It is worth noting that the technical features proposed in this technical solution, such as the gas flow sensor 3, the fan 4, and the dust filter plate 19, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: First, place the garment on the testing platform 12. Then, close the movable door of the testing air box body 1 and open the second electric telescopic rod 10. The second electric telescopic rod 10 pushes the fixing plate 11 downward to fix the garment around its sides. Turn on the fan 4 to draw air into the filter box 5 through the suction pipe. Air enters through the air inlet 7 and is filtered by the dust filter plate 19 to prevent dust from being blown onto the garment and causing blockage, thus preventing it from affecting the air permeability test and improving the accuracy of the test. At the same time, it prevents dust from affecting the testing device. The air is sprayed onto the garment through the exhaust pipe, horizontal pipe 14 and air jet head 17. The gas passes through the garment and enters the connecting pipe 2 for exhaust. The gas flow is then measured by a gas flow sensor. Device 3 detects the circulating gas and views the detection results through the display panel of gas flow sensor 3. At the same time, the first electric telescopic rod 901 is opened, which pushes the toothed plate 902 to move. The toothed plate 902 drives the gear 903 to rotate. The gear 903 drives the horizontal tube 14 and the jet head 17 to adjust their angles through the adjusting rod 16. Air blowing detection can be performed on the clothing at different angles. After the detection is completed, the motor 601 is turned on. The motor 601 drives the transmission rod 602 and the cam 603 to rotate and apply pressure to the dust filter plate 19 and the spring 18. After rotating to the reset position, the pressure is released. The elasticity of the spring 18 drives the dust filter plate 19 to shake, which can cause the dust attached to the dust filter plate 19 to fall off.
