[0031] 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.

[0032] Example 1

[0033] Please see Figures 1-2 One type of medical mask filter detection device includes:

[0034] The test box 1 contains a transmission box 2, and one end of the transmission box 2 is provided with a transmission port 3.

[0035] The second sampling container 8 is located inside the detection chamber 1;

[0036] The third sampling container 9 is snapped onto the upper end of the second sampling container 8. The interior of the third sampling container 9 is provided with a perforated plate 10, and the third sampling container 9 is connected to the second sampling container 8 through the perforated plate 10.

[0037] Both the third sampling container 9 and the second sampling container 8 contain aerosols, and the mask is placed on the top of the third sampling container 9.

[0038] The lower end of the second sealing cap 6 is inserted into the upper end of the third sampling container 9 to limit the mask.

[0039] The storage roller 7 is rotatably connected to both sides of the third sampling container 9. The outer surface of the storage roller 7 is provided with a through-hole groove 15, which passes through the storage roller 7. One side of the mask is connected to the inside of the through-hole groove 15. By rotating the storage roller 7, the mask is pulled to change its position inside the third sampling container 9.

[0040] A transmission tube is sleeved between the transmission port 3 and the second sealing cover 6, through which air containing bacteria is transmitted to the sealing cover 5 and the second sealing cover 6.

[0041] Aerosol is placed inside the first sampling container 4, the second sampling container 8, and the third sampling container 9. A mask is placed on top of the third sampling container 9. The sealing cap 5 and the second sealing cap 6 are inserted into the top of the first sampling container 4 and the mask, respectively. Two flexible tubes are used to connect the top of the sealing cap 5 to the top of the second sealing cap 6 and to the two transmission ports 3, respectively. Air containing bacteria is transmitted to the sealing cap 5 and the second sealing cap 6 through the transmission ports 3 and the flexible tubes. The aerosol inside the first sampling container 4 comes into complete contact with the air containing bacteria. The air filtered by the mask inside the third sampling container 9 comes into contact with the aerosol. After a period of transmission, the aerosol inside the first sampling container 4 and the aerosol inside the third sampling container 9 are taken out for testing and comparison to determine whether the mask has passed the filtration test.

[0042] Furthermore, a first support frame 11 and a second support frame 12 are sequentially installed inside the third sampling container 9. A through groove 13 is provided between the first support frame 11 and the second support frame 12, and the through groove 13 penetrates the third sampling container 9.

[0043] The mask slides through the groove 13.

[0044] Furthermore, according to Figure 2 As shown, before testing, the mask is passed through the through slot 13 and connected to both sides of the mask by two storage rollers 7. After testing for a period of time, the two storage rollers 7 are rotated synchronously, so that one storage roller 7 rolls up the mask and the other storage roller 7 loosens the mask, thereby sliding the other parts of the mask to the lower end of the second sealing cover 6, so as to detect the other parts of the mask, thereby achieving complete detection of the mask and improving the detection effect.

[0045] It should be noted that by passing one side of the mask through the through-hole groove 15, the storage roller 7 can pull the mask to roll up and wrap around the outer surface of the storage roller 7 when the storage roller 7 rotates.

[0046] Example 2

[0047] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-3 The first support frame 11 has a first piston chamber 18 inside, and a piston plate 20 is slidably connected inside the first piston chamber 18. A compression plate 21 is installed at the lower end of the piston plate 20. The compression plate 21 is used to press against the mask and seal the through groove 13.

[0048] A spring is also installed inside the first support frame 11, and the piston plate 20 is connected to the first support frame 11 by the spring.

[0049] according to Figure 3 As shown, in order to reduce the escape of bacteria-containing air through the through-slot 13 during testing, which would affect the test results, compression plates 21 are slidably connected to both sides of the through-slot 13. When the mask is slidably connected to the through-slot 13, the compression plates 21 press against the mask and press the mask against the second support frame 12. In this way, the two compression plates 21 seal both ends of the through-slot 13, thereby reducing the escape of bacteria-containing air.

[0050] Example 3

[0051] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-4 The third sampling container 9 is provided with a second piston chamber 23, and a rack 17 is slidably connected inside the second piston chamber 23;

[0052] A gear 16 is installed at one end of the receiving roller 7, and the rack 17 meshes with the gear 16;

[0053] A torque spring is fitted at the other end of the collecting roller 7, and the collecting roller 7 is connected to the third sampling container 9 through the torque spring.

[0054] The first piston chamber 18 is also provided with a transmission hole 19 and a flow hole 22. The transmission hole 19 is located above the piston plate 20, and the flow hole 22 is located below the piston plate 20.

[0055] The other end of the transmission hole 19 is connected to the interior of the second piston chamber 23;

[0056] The inside of the testing box 1 is also equipped with a first sampling container 4, and the upper end of the first sampling container 4 is connected with a sealing cap 5 by a snap fastener.

[0057] The inside of the test box 1 is also equipped with an air pump, one end of which is connected to the air supply pipe and the flow hole 22;

[0058] according to Figure 3 and Figure 4 As shown, when the mask position needs to be adjusted, the transmission port 3 stops transmitting air containing bacteria. At this time, air is transmitted to the flow hole 22 by an air pump, using the air to compress the piston plate 20 to slide upward, thereby causing the piston plate 20 to drive the compression plate 21 to slide upward, so that the compression plate 21 no longer compresses the mask. When the piston plate 20 slides to the limit, its transmission hole 19 will be exposed, thereby connecting the transmission hole 19 with the interior of the first piston chamber 18, so that the high-pressure air in the first piston chamber 18 can enter the transmission hole 19. Figure 4 As shown, high-pressure air is transmitted to the second piston chamber 23 through the transmission hole 19, thereby squeezing the rack 17 to slide to one side. The rack 17 meshes with the drive gear 16 to rotate, and the gear 16 drives the collection roller 7 to rotate. In turn, the rotation of the collection roller 7 pulls one end of the mask to wrap around the outer surface of the collection roller 7, thus realizing the change of the mask position in Embodiment 1.

[0059] It should be noted that a torque spring is connected between the receiving roller 7 and the third sampling tank 9, and the receiving roller 7 is rotated and reset by the torque spring.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
