[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the utility model provides a sealing detector, including a control body 1, a glass tank body 2 is fixedly provided on the left side of the control body 1, an inflation tube 3 is fixedly provided at the output end of the control body 1, and a pressure pump 4 is connected to the other end of the inflation tube 3. The pressure pump 4 is fixed to the control body 1, and an inflation plate 5 is connected to the output end of the pressure pump 4. The control body 1 controls the pressure pump 4 to perform an inflation operation by blowing air into the inflation plate 5 located inside the glass tank body 2. The bottom end of the inflation plate 5 also includes an inflation anti-falloff component 6;

[0028] The inflation anti-slip component 6 includes a through pipe 61 connected to the bottom end of the inflation plate 5, a fixing ring 62 is spirally arranged on the outside of the other end of the through pipe 61, a leather bag 63 is fixedly arranged on the outside of the fixing ring 62, the bottom end of the leather bag 63 is connected to the air inlet pipe 64, and a sealing ball 66 is fitted on the outlet end of the air inlet pipe 64. When the injected gas enters the interior of the sealing detection item, the leather bag 63 can be controlled to inflate and swell, and the leather bag 63 can be controlled to close the air inlet of the sealing detection item to form a closed structure and enhance the sealing stability.

[0029] Specifically, a spring 65 is fixedly provided on the outside of the sealing ball 66, and the other end of the spring 65 is fixedly provided to the air inlet pipe 64. The leather bag 63 adopts a deformable leather membrane, and becomes spherical after the leather bag 63 is inflated. During the inflation process, the sealing ball 66 located inside the air inlet pipe 64 can be pushed out by inflation, thereby forming an inflation channel, inflating the sealing detection item, and checking whether the sealing detection item is leaking after being inflated.

[0030] Furthermore, the left side of the top of the glass container 2 also includes a sealing test component;

[0031] The sealing test assembly includes a connecting block 7 connected to the glass jar body 2, and an air tube 8 is fixedly provided on the top of the connecting block 7. The other end of the air tube 8 is spirally provided with a U-shaped tube 9. The interior of the U-shaped tube 9 is filled with a medium, such as water. A fastening cap 10 is spirally provided inside the other end of the U-shaped tube 9, and a vertical shaft 11 is provided inside the fastening cap 10. One end of the vertical shaft 11 located inside the U-shaped tube 9 is fixedly provided with a sliding plug 13, and the sliding plug 13 is fitted with the U-shaped tube 9. The medium: water is filled into the interior of the U-shaped tube 9 to seal it. After inflation, if air leakage occurs, it can be filled into the interior of the U-shaped tube 9 through the air tube 8, and through the medium: water inside the U-shaped tube 9, it can be observed whether there are bubbles in the water inside the U-shaped tube 9, so as to determine whether there is air leakage. After the gas is inflated to the other side of the U-shaped tube 9, it can push the water level inside the U-shaped tube 9 to deviate, or push the spring 2 12 outside the vertical shaft 11 to deform, thereby effectively improving the convenience of observation.

[0032] It is worth noting that a spring 2 12 is sleeved on the outer side of the vertical axis 11, and the spring 2 12 is located between the fastening cap 10 and the sliding plug 13. An air hole 14 is opened below the front outlet of the U-shaped tube 9. After gas is filled into the interior of the U-shaped tube 9, the fastening cap 10 can be screwed to move to the top of the air hole 14, and the gas can be discharged before re-measurement.

[0033] Among them, the control body 1 (MFY-01A capsule sealing detection instrument), glass tank body 2, pressure pump 4, and leather bag 63 are existing technologies and will not be repeated; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be repeated.

[0034] Working principle and process:

[0035] The staff connects the items that need to be tested for air tightness and puts them into the inflation anti-falling component 6 inside the glass jar body 2, inserts the air inlet pipe 64 into the entry of the air tightness test items, and then covers the lid above the glass jar body 2 above the opening of the glass jar body 2. After the sealing is completed, the pressure pump 4 is controlled by the control body 1 to work, and the air is filtered by the inflation pipe 3 through the filtering structure, and then the air is filled into the interior of the inflation plate 5, and the air is filled into the interior of the inflation anti-falling component 6 through the through pipe 61, and the air is filled into the interior of the leather bag 63 outside the fixing ring 62 through the through pipe 61. First, the leather bag 63 is sealed. The bag 63 is inflated to form a limiting structure inside the air-tightness detection article, closing the inlet, thereby reducing the risk of the air inlet pipe 64 detaching from the inlet of the air-tightness detection article, thereby improving the stability of use. After the bladder 63 is inflated to the maximum extent, the sealing ball 66 can be pushed to detach from the outlet of the air inlet pipe 64, and the tension spring 65 is stretched. After the inflation is completed, the sealing ball 66 can be controlled to enter the outlet of the air inlet pipe 64 by being pulled by the spring 65 to seal it. Whether bubbles are generated in the water inside the glass jar body 2 can be used to determine whether the air-tightness detection article is leaking.

[0036] At the same time, before conducting the air tightness test, you can first inflate it to determine whether the glass jar body 2 has any leakage. If there is any leakage, the gas enters the inside of the air pipe 8 through the connecting block 7 and inflates into the inside of the U-shaped tube 9, and observe whether there are bubbles in the water inside the U-shaped tube 9, or whether the water heights on both sides of the U-shaped tube 9 are different, or observe whether the vertical axis 11 moves up and down. If there is a problem, reseal it and test it again. If there is no problem, screw the fastening cap 10 to the top of the air hole 14 to discharge the gas, and the spring 2 12 pushes the sliding plug 13 to reset, and re-tighten the fastening cap 10 to the inside of the U-shaped tube 9.
