[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, a convenient compressed air airborne bacteria testing and protection device includes a wind box 1. The bottom of the wind box 1 is provided with four support leg mechanisms 2 arranged in a rectangular array. An air outlet grille 11 that penetrates the inner cavity is fixedly installed at the bottom of the wind box 1. Handles 12 are fixedly installed on the left and right sides of the top of the wind box 1. An airborne bacteria sampling head 3 is provided below the air outlet grille 11. A fan 13 is fixedly installed in the inner cavity of the wind box 1. An external threaded ring 14 that penetrates the inner cavity is fixedly connected at the center of the top of the wind box 1. An internal threaded ring 15 is threaded on the outer wall of the external threaded ring 14. A filter plate 151 is fixedly installed on the inner ring of the internal threaded ring 15. Rotating handles 152 are fixedly installed on the left and right sides of the top of the internal threaded ring 15 for rotating and disassembling the internal threaded ring 15 and lifting it up. In use, the bellows 1 is lifted with the handle 12 and the air outlet grille 11 is aligned with the airborne bacteria sampling head 3 and lowered. The support leg mechanism 2 is used for support to complete the placement. By starting the fan 13 inside the bellows 1, the outside air is filtered through the filter plate 151 of the inner ring of the inner threaded ring 15 and then blown to the airborne bacteria sampling head 3 through the air outlet grille 11, thus ensuring the cleanliness of the airflow. Excess airflow will be continuously discharged from the bottom of the transparent soft curtain 211. At the same time, when it is necessary to clean the filter plate 151, it is only necessary to hold the rotating handle 152 and rotate the entire inner threaded ring 15 to rotate and disassemble it by means of the threaded connection between the inner threaded ring 15 and the outer threaded ring 14.

[0016] like Figure 4 As shown, each of the four corners of the bellows 1 has an L-shaped groove 16 extending through its bottom. Each of the four L-shaped grooves 16 has a bolt hole 161 on its two vertical surfaces. Each of the four support leg mechanisms 2 includes a support leg 21. Each of the four support legs 21 has an L-shaped mounting plate 24 fixedly installed at its top. Each of the four L-shaped mounting plates 24 is respectively engaged with the four L-shaped grooves 16. Each of the four L-shaped mounting plates 24 has a through-hole 25 on its two vertical surfaces. Each of the four L-shaped mounting plates 24 has a fixing bolt 26 in its inner ring. The fixing bolt 26 passes through the 25 and is threaded into the bolt hole 161 to lock the L-shaped mounting plate 24. Each of the four support legs 21 has a support foot 22 fixedly installed at its bottom. Each of the four support feet 22 has a rubber pad 23 fixedly adhered to its bottom. To facilitate the transportation and storage of the bellows 1, all four support legs 21 can be separated by the combination of the L-shaped mounting plate 24 and the L-shaped groove 16. During installation, the fixing bolts 26 are passed through the mating holes 25 and threaded into the bolt holes 161 to complete the assembly, thereby connecting the bellows 1 and the support legs 21. When the support legs 21 are placed, the rubber pads 23 at the bottom of the support feet 22 can also improve the anti-slip properties, preventing abnormal noises or large positional shifts caused by the start of the fan 13 inside the bellows 1.

[0017] like Figure 5 As shown, a transparent soft curtain 211 is fixedly installed on the outer wall of one of the four support legs 21. The transparent soft curtain 211 wraps around the four support legs 21. A Velcro 212 is fixedly glued to one side of the outer surface of the transparent soft curtain 211, and a Velcro 213 is fixedly glued to the other side of the inner surface of the transparent soft curtain 211. After the transparent soft curtain 211 wraps around the four support legs 21, the Velcro 213 and the Velcro 212 are glued to each other. A storage strap 214 is fixedly connected to the side of the transparent soft curtain 211 away from the Velcro 213. Velcro 3 215 is fixedly glued to both sides of the storage strap 214. The Velcro 3 215 is used to roll up and glue the storage strap 214 after the transparent soft curtain 211 is wrapped around the outer wall of the support leg 21. A skirt curtain is provided on the top outer side of the transparent soft curtain 211 to cover the gap between the top of the transparent soft curtain 211 and the bottom of the bellows 1. The inner circle of the skirt curtain is fixedly connected to the side of the bellows 1. One end of the transparent soft curtain 211 on the outer wall of the support leg 21 of one of the four support leg mechanisms 2 is wrapped around the outer walls of the other three support legs 21 and then returned. At this time, the transparent soft curtain 211 is taut on the outer wall of the support leg 21. Then, the Velcro 213 and Velcro 1 212 are glued together to complete the wrapping of the outer walls of the four support legs 21, forming an environmental protection for airborne bacteria testing. When the equipment is not in use, the Velcro 213 and Velcro 1 212 can be torn apart, and the transparent soft curtain 211 can be rolled up and wrapped around the connected support leg 21. Finally, the storage strap 214 is wrapped around the wrapped transparent soft curtain 211 and glued with the double-sided Velcro 3 215 to complete the fixation, realizing the quick storage of the transparent soft curtain 211.

[0018] The working principle of this portable compressed air airborne bacteria testing and protection device will be explained in detail below.

[0019] like Figure 1-5 As shown, in use, the bellows 1 is lifted using the handle 12, and the air outlet grille 11 is aligned with the airborne bacteria sampling head 3 and lowered. The support leg mechanism 2 is used for support. Then, one end of the transparent soft curtain 211 on the outer wall of one of the four support legs 21 is wrapped around the outer walls of the other three support legs 21 and returned. At this point, the transparent soft curtain 211 is taut on the outer wall of the support leg 21. The Velcro 213 and Velcro 212 are then fastened together to complete the wrapping of the four support legs 21. The fan 13 inside the bellows 1 is then activated, drawing outside air through the filter plate 151 of the inner threaded ring 15 before it passes through the air outlet grille 11 and is blown towards the airborne bacteria sampling head 3, ensuring clean airflow. Excess airflow is continuously discharged from the bottom of the transparent soft curtain 211. When cleaning the filter plate 151, simply hold the rotating handle 152 and rotate the entire inner threaded ring. The threaded ring 15 can be rotated and disassembled by means of the threaded connection between the inner threaded ring 15 and the outer threaded ring 14. When the equipment is not in use, the Velcro 213 and Velcro 12 can be torn apart and the transparent soft curtain 211 can be rolled up and wrapped around one of the connected support legs 21. Finally, the transparent soft curtain 211 is fixed by using the storage strap 214 to wrap around the wrapped transparent soft curtain 211 and using the double-sided Velcro 3 215 to complete the fixation, so as to achieve quick storage of the transparent soft curtain 211. In order to facilitate the transportation and storage of the bellows 1, all four support legs 21 can be separated by means of the L-shaped mounting plate 24 and the L-shaped groove 16. During installation, the fixing bolt 26 is passed through the docking hole 25 and threadedly connected to the bolt hole 161 to complete the combination, so as to connect the bellows 1 and the support legs 21. When the support legs 21 are placed, the rubber pad 23 at the bottom of the support foot 22 can also improve the anti-slip performance and avoid abnormal noise or large displacement due to the start of the fan 13 in the inner cavity of the bellows 1.
