Example

[0024] See also Figure 1-5The utility model provides an all-in-one machine for testing the fit and breathability of facial masks, comprising a facial mask chamber 1, a curved support plate 3 and a curved pressure plate 13. The interior of the facial mask chamber 1 is fixed with the curved support plate 3 through a partition 2, the bottom end of the facial mask chamber 1 is provided with an air intake assembly 4, the top end of the facial mask chamber 1 is connected with a transparent tube 7 through a top plate 5, the interior of the transparent tube 7 is provided with a hollow float 8, the bottom end of the top plate 5 is fixedly installed with a cylinder 10 through a support 9, the telescopic rod of the cylinder 10 is connected with a connecting seat 12 through a buffer assembly 11, and the bottom end of the connecting seat 12 is fixed with a curved pressure plate 1 3. By driving the cylinder 10 to lift the buffer assembly 11, the curved pressure plate 13 can be driven to rise, and the mask to be tested can be laid on the curved support plate 3. By driving the cylinder 10 to control the buffer assembly 11 to descend, the curved pressure plate 13 can apply pressure to the mask. During the pressure application process, the buffer assembly 11 can contract under pressure, which can provide a buffer for the pressure on the mask, avoid the phenomenon of excessive pressure, and prevent damage to the mask. The surfaces of the curved support plate 3 and the curved pressure plate 13 are both provided with a ventilation groove 14, and the mask hole blocking plate 15 is fixed inside the ventilation groove 14;

[0025] The bottom end of the top plate 5 is welded to the top of the mask chamber 1, and an air outlet 6 is opened in the middle of the top plate 5. The diameter of the air outlet 6 is smaller than the diameter of the hollow float 8. The air outlet 6 can ensure the circulation of air inside the mask chamber 1 and the transparent tube 7. The air flow passing through the hollow float 8 can drive the hollow float 8 to rise.

[0026] A sealing door 17 is hinged on the surface of the mask room 1, and a transparent observation window 18 is fixedly provided on the surface of the sealing door 17. By opening the sealing door 17, the mask can be taken in and out, and by closing the sealing door 17, air leakage in the mask room 1 can be prevented. Example

[0027] The air intake assembly 4 includes a filter box 401 and a filter screen 405. An air inlet pipe 402 is fixedly provided on the top of the filter box 401. A flange 403 is welded to the air inlet end of the air inlet pipe 402. The top of the filter box 401 is welded to the bottom end of the mask chamber 1 through a connecting ring 404. A filter screen 405 is fixedly provided on the surface of the connecting ring 404. Air flow can be transported into the filter box 401 through the flange 403 and the air inlet pipe 402. When the air flow enters the mask chamber 1 through the connecting ring 404, the filter screen 405 can filter dust in the air flow, thereby ensuring the cleanliness of the air flow and preventing dust from adhering to the mask.

[0028] A sealing cover 406 is hinged on the surface of the filter box 401, and a bottom plate 407 is fixed to the bottom end of the filter box 401. Positioning holes are provided on the surface of the bottom plate 407, and the bottom plate 407 can be fixed through the positioning holes. By opening the sealing cover 406, the dust filtered inside the filter box 401 can be cleaned. Example

[0029] The buffer assembly 11 includes a buffer plate 1101. The middle part of the top of the buffer plate 1101 is fixedly connected to the telescopic rod of the cylinder 10. The buffer plate 1101 is slidably connected to two guide rods 1103. The surface of the guide rod 1103 is provided with a spring 1105. The bottom end of the guide rod 1103 is fixedly connected to the top of the connecting seat 12. The buffer plate 1101 is driven down by the cylinder 10. The buffer plate 1101 can compress the spring 1105. The spring 1105 can contract under pressure, thereby providing a buffer between the curved pressure plate 13 and the curved support plate 3.

[0030] Two rod grooves 1102 are formed on the surface of the buffer plate 1101, and slide grooves 16 are formed on both sides of the bottom end of the support 9. The guide rod 1103 is slidably connected with the rod grooves 1102 and the slide grooves 16. The slide grooves 16 and the rod grooves 1102 can guide the guide rod 1103 to prevent the guide rod 1103 from tilting;

[0031] A pull plate 1104 is fixed on the surface of the guide rod 1103, and the pull plate 1104 is located at the top of the buffer plate 1101. The top of the spring 1105 overlaps with the bottom end of the buffer plate 1101. The pull plate 1104 can prevent the guide rod 1103 from falling off, and the buffer plate 1101 can lift the curved pressure plate 13 through the pull plate 1104.

[0032] When in use, the staff first opens the sealing door 17, and then lifts the buffer assembly 11 through the cylinder 10, driving the curved pressure plate 13 to rise, increasing the distance between the curved pressure plate 13 and the curved supporting plate 3, and then laying the mask to be tested on the curved supporting plate 3, and then driving the cylinder 10 to control the buffer assembly 11 to descend, so that the curved pressure plate 13 applies pressure to the mask. During the pressure application process, the spring 1105 of the buffer assembly 11 is compressed and can contract, which can provide a buffer for the pressure on the mask, avoid the phenomenon of excessive pressure, and prevent damage to the mask. The curved supporting plate 3 can simulate the human face and fit with the curved pressure plate 13. Relying on its curved surface, the fit of the mask can be tested, and the wrinkle condition of the mask can be detected;

[0033] After the mask is positioned, the staff closes the sealing door 17 and delivers air to the filter box 401 through the flange 403 of the air intake assembly 4 and the air inlet pipe 402. When the air enters the mask chamber 1 through the connecting ring 404, the filter 405 can filter the dust in the air flow, thereby ensuring the cleanliness of the air flow and preventing dust from adhering to the mask. Under the stable pressure of the cylinder 10 and the buffer assembly 11, the mask can be prevented from loosening and falling off. After passing through the mask, the air flow can enter the transparent tube 7 through the air outlet 6. The hollow float 8 can rise by relying on the air flow passing through the mask, thereby testing the air permeability of the mask.

[0034] During the test of the air permeability of the mask, the curved support plate 3 and the curved pressure plate 13 can press the edges of the mask, and the mask hole blocking plate 15 can press the seams at the openings of the mask to prevent air leakage at the edges and openings of the mask, thereby ensuring the test accuracy. After the test is completed, the staff opens the sealing door 17 and controls the cylinder 10 to lift the buffer plate 1101. The buffer plate 1101 can lift the curved pressure plate 13 through the pull plate 1104, and the mask can be removed. The staff opens the sealing cover 406 of the air intake assembly 4 to clean the filtered dust.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
