[0023] Please see Figures 1-4 A portable medical oxygen supply valve sealing detection device includes a base box 1. A pressure gauge 9 is bolted to the left side of the inner cavity of the base box 1, and a left hose 10 is connected to the right side of the pressure gauge 9. A miniature air pump 13 is fixedly connected to the front side of the right side of the inner cavity of the base box 1, and a right hose 12 is connected to the rear side of the miniature air pump 13.

[0024] A spraying mechanism 11 is bolted to the rear right side of the inner cavity of the base box 1. The spraying mechanism 11 includes a micro water pump 15. The water outlet of the micro water pump 15 is connected to a water supply hose 14. A spray pipe 16 is connected to the left side of the water supply hose 14. A box cover 4 is hinged to the top of the rear side of the base box 1. A handle 2 is bolted to the top of the box cover 4. The handle 2 makes it easy for people to lift and carry the device. Shoulder straps 3 are fixedly connected to the left and right sides of the base box 1.

[0025] Please see Figure 3 The water inlet pipe of the miniature water pump 15 extends to the left side of the inner cavity of the base box 1. A water inlet cap 19 is threadedly connected to the rear side of the top left side of the base box 1. By setting the water inlet cap 19, it is convenient to add foam water to the interior of the rear side of the base box 1.

[0026] Please see Figure 3 A drive motor 18 is fixedly connected to the inner cavity on the left side of the rear side of the base box 1. By setting the drive motor 18, the stirring rod 17 can be driven to rotate to stir the foam water, so as to avoid the foam water from settling and affecting the detection effect. The output shaft of the drive motor 18 passes through the inner cavity of the base box 1 and the stirring rod 17 is fixedly connected to its surface.

[0027] Please see Figure 3 and Figure 4 The valve body 20 is placed in the middle of the top of the base box 1. Electric push rods 21 are bolted to the left and right sides of the top of the base box 1. By setting the electric push rods 21, the valve body 20 can be clamped and positioned by pushing the positioning push plate 22 to prevent it from moving randomly. The output end of the electric push rod 21 is fixedly connected to the positioning push plate 22.

[0028] Please see Figure 1 and Figure 2The base box 1 has a storage slot 8 on the front side of the top left side. The power cord of the device can be conveniently stored by the storage slot 8. The front sides of the base box 1 and the box cover 4 are connected by bolts with a latch 6.

[0029] Please see Figure 1 and Figure 3 A dustproof net 5 is fixedly connected to the front right side of the base box 1. By setting the dustproof net 5, dust and other impurities in the outside air can be filtered to prevent them from being sucked into the micro air pump 13. A rubber bracket is fixedly connected to the rear top of the base box 1. By setting the rubber bracket, the nozzle 16 can be easily clamped and fixed.

[0030] Please see Figure 2 A storage drawer 7 is slidably connected to the bottom front side of the base box 1. The storage drawer 7 makes it convenient to store the testing tools. The front side of the storage drawer 7 has a pull groove.

[0031] Please see Figure 4 A control panel 23 is fixedly connected to the front of the top of the base box 1. Pipe connectors are fixedly inserted into the inner sides of the left hose 10 and the right hose 12. By setting the pipe connectors, it is easy to fix and connect them to the valve body 20.

[0032] When in use, connect this device to an external power source via a power cord. After opening the cover 4, fix the left hose 10 and right hose 12 to the left and right sides of the valve body 20 respectively. Then, control the micro air pump 13 to pressurize the right hose 12 and valve body 20 via the control panel 23. The pressure gauge 9 detects the air pressure inside the pipe.

[0033] Once the preset air pressure is reached, the valve body 20 is closed and the micro air pump 13 is stopped. At this time, the air pressure is observed through the pressure gauge 9 to see if the air pressure changes. If the air pressure remains unchanged within a certain period of time, it indicates that the air tightness is qualified. If the air pressure drops, it indicates that there is a leak. At this time, the micro water pump 15 is controlled to work to extract the foam water. Personnel hold the spray nozzle 16 and spray the foam water onto the surface of the valve body 20. This will cause foam to rise at the leak point, allowing personnel to quickly determine the leak location and effectively improve the detection efficiency.

[0034] After the test is completed, remove the valve body 20, turn off the power, close the cover 4 and lock it with the buckle 6. Personnel can carry the device by carrying it on their back with the shoulder strap 3. This makes it more convenient to carry and provides all-round protection for the testing components, preventing them from being bumped by external objects and extending their service life.

[0035] In summary, this portable medical oxygen supply valve sealing detection device, through the coordinated use of the base box 1, handle 2, shoulder strap 3, box cover 4, pressure gauge 9, left hose 10, spraying mechanism 11, right hose 12 and miniature air pump 13, solves the problems of inconvenience in carrying, poor protection efficiency, easy damage from impacts, inability to quickly and accurately determine the leak location, and reduced detection efficiency.
