[0027] First, the present invention can detect the dust filtering and interception effect of the mask based on the degree of color change of the water in the transparent tube. The pressure valve is provided to increase the air pressure in the front half of the output end tube. When the pressure exceeds the set value of the pressure valve, a pulse effect can be formed, causing air to bulge out of the extension hose at a constant frequency. The extension hose is significantly deformed due to the reaction force, and the water in the transparent tube is stirred. At the same time, the better the air permeability of the mask, the faster the air pressure in the output end tube increases, the higher the frequency of opening of the pressure valve and deformation of the extension hose, and the tester can intuitively judge the air permeability of the mask.

[0028] Secondly, since the connecting carrier plate 1 and the connecting carrier plate 2 are connected by the vibration spring 1 and the vibration spring 2, when the two micro air pumps are in operation, they can cause the vibration spring 1 and the vibration spring 2 to vibrate, and drive the two negative pressure cone-mouthed cylinders to vibrate, so that the powder supply unit in the negative pressure cone-mouthed cylinder can also vibrate synchronously, thereby shaking out the pigment powder, thereby simulating a dusty environment, and making the air mixed with the pigment powder pass through the mask for filtration to test the dust filtering effect of the mask;

[0029] Third: When the extension hose is displaced in the water due to the strong airflow, it can drive the corresponding paddle to move, thereby improving the mixing effect of the water. At the same time, when the paddle moves, part of the water can flow at the turbulent hole, which is conducive to promoting the absorbed pigment powder to dissolve quickly in the water. The darker the color of the water in the transparent tube, the worse the dust filtering effect of the mask. Conversely, the darker the color, the better the quality of the mask.

[0030] At the same time, after the detection work of the present invention is completed, the detection personnel can take a picture of the inner side of the mask to record the degree of penetration of the pigment powder. The detection method of the present invention can better ensure the reliability of the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] The present invention provides a method for quickly detecting the quality of a medical mask through improvement. The technical solution of the present invention is:

[0044] like Figures 1 to 8As shown, an embodiment of the present invention provides a method for quickly detecting the quality of a medical mask. The method for quickly detecting the quality of a medical mask is based on a detection device, which includes:

[0045] The support assembly includes a bottom plate 11, and a support plate 33 is rotatably mounted on the top of the bottom plate 11. An extension column 32 is fixedly mounted at the center of the support plate 33. The support plate 33 and the extension column 32 can provide good support for the plate 3, and the top of the extension column 32 is fixedly mounted with the plate 3. Two pairs of mounting screw holes 301 are opened on the plate 3;

[0046] The plurality of transparent tubes 4 are all screwed to the two pairs of mounting screw holes 301 through threads; through the above structure, the transparent tubes 4 can be stably mounted on the table 3 through the mounting screw holes 301 .

[0047] Two negative pressure components, the negative pressure components are used to simulate human inhalation, each negative pressure component includes a micro air pump 53 with the same power, and the air outlet end of each micro air pump 53 is fixedly connected to a corrugated hose 52, and the end of each corrugated hose 52 is fixedly connected to an output end tube 5, one end of the output end tube 5 is inserted into the transparent cylinder 4 and is fixedly connected to an extension hose 501, and the two output end tubes 5 are fixedly installed with a pressure valve 51 at one end close to the corrugated hose 52; through the above structure, the negative pressure component can make air pass through the mask on the subsequent fixed base 57 through the micro air pump 53, and when dust passes through the mask, it can be input into the transparent cylinder 4 through the output end tube 5, and then can be adjusted according to the actual situation. The degree of color change of the water in the transparent tube 4 is used to detect the filtering and intercepting effect of the mask on dust; the pressure valve 51 is used to increase the air pressure in the front half of the output end tube 5. When it is higher than the set value of the pressure valve 51, a pulse effect can be formed, so that air bulges out from the extension hose 501 at a constant frequency, and the extension hose 501 is deformed more obviously due to the reaction force, and the water in the transparent tube 4 is stirred. At the same time, the better the breathability of the mask, the faster the air pressure in the output end tube 5 rises, the higher the opening frequency of the pressure valve 51 and the deformation frequency of the extension hose 501. The tester can intuitively judge and compare the breathability performance of the mask.

[0048] The powder supply clamping assembly is used to fix the mask to be tested and simulate the dust environment. The powder supply clamping assembly includes an upper plate 2 and a lower plate 21, and a pair of negative pressure cone-mouth cylinders 56 and a pair of fixed bases 57 are arranged between the upper plate 2 and the lower plate 21. The two negative pressure cone-mouth cylinders 56 are each provided with a powder supply unit. The fixed base 57 is generally in the shape of a cone. One end of the two fixed bases 57 is provided with an annular groove 572, and one end of the negative pressure cone-mouth cylinder 56 is adapted to the annular groove 572; through the above structure, when fixing the mask, the mask can be placed on one side of the fixed base 57, and then the two negative pressure cone-mouth cylinders 56 are installed. The annular groove 572 is squeezed by the negative pressure cone-mouth cylinders 56 to fix the mask, avoid gaps between the mask and the fixed base 57, and prevent adverse effects on the detection.

[0049] Two connecting carrier plates 1 582 and two connecting carrier plates 2 59 are symmetrically arranged at the upper and lower ends of the two negative pressure cone-mouth cylinders 56. A vibration spring 1 583 is fixedly installed between the two connecting carrier plates 1 582 and the upper plate 2 and the lower plate 21. A vibration spring 2 591 is fixedly installed between the two connecting carrier plates 2 59 and the upper plate 2 and the lower plate 21. The two sides of the two fixed bases 57 are respectively connected to a connecting carrier plate 1 582 and a connecting carrier plate 2 59. Fixed connection; through the above structure, since the connecting carrier plate 1 582 and the connecting carrier plate 2 59 are connected by the vibration spring 1 583 and the vibration spring 2 591, when the two micro air pumps 53 are in operation, the micro air pump 53 itself generates vibrations, which can cause the vibration spring 1 583 and the vibration spring 2 591 to vibrate, and drive the two negative pressure cone-mouth cylinders 56 to vibrate, so that the powder supply unit in the negative pressure cone-mouth cylinder 56 can also shake synchronously, thereby shaking out the pigment powder, thereby simulating a dust environment.

[0050] The rapid quality detection method for medical masks specifically includes the following steps:

[0051] Step 1: Place the two masks to be tested on the fixed base 57 and fix the masks using the negative pressure cone 56 and the annular sink 572;

[0052] Step 2: Use the negative pressure component to simulate human inhalation to create a negative pressure state between the mask and the fixed base 57;

[0053] Step 3: Use the powder supply unit to simulate a dusty environment and observe the color change of the transparent water in the corresponding transparent tube 4;

[0054] Step 4: The darker the color of the water in the transparent tube 4, the worse the dust filtering effect of the surface mask. Conversely, the darker the color, the better the quality of the mask.

[0055] Furthermore, connecting end blocks 58 are fixed between the two sides of the two negative pressure cone-mouth cylinders 56 and the connecting carrier plate 1 582 and the connecting carrier plate 2 59, and internal threaded end blocks 571 are fixedly installed at both ends of one side of the two fixed bases 57, and a fixing screw 581 is threadedly connected between each connecting end block 58 and the internal threaded end block 571; through the above structure, the negative pressure cone-mouth cylinder 56 can be pulled away from the fixed base 57 first, and after the mask is placed, the negative pressure cone-mouth cylinder 56 is pre-pressed to the mask under the resetting action of the vibration spring 1 583. At this time, the fixing screw 581 is screwed and fixed to the internal threaded end block 571, thereby completing the fixation of the mask.

[0056] As a further solution of the present invention, each powder supply unit includes a powder storage barrel 562 arranged inside the negative pressure cone-mouth cylinder 56, and a plurality of fixed connecting pieces 561 are fixedly connected between the two ends of the powder storage barrel 562 and the negative pressure cone-mouth cylinder 56. A plurality of evenly distributed powder outlet holes 563 are provided on the two powder storage barrels 562, and one end of the two powder storage barrels 562 is clamped with a plug 564, and the powder storage barrel 562 specifically stores pigment powder; through the above structure, when the powder supply unit vibrates following the negative pressure cone-mouth cylinder 56, the pigment powder inside the powder storage barrel 562 can be shaken out, and along with the negative pressure dust extraction effect of the negative pressure component, the air mixed with pigment powder can be filtered through the mask, so as to test the dust filtering effect of the mask.

[0057] Furthermore, an air duct 574 is opened at the center position of the two fixed bases 57, and an exhaust pipe 55 is fixedly connected between the air duct 574 and the air inlet end of the adjacent micro air pump 53; when the micro air pump 53 is running, the exhaust operation can be completed through the cooperation of the exhaust pipe 55 and the air duct 574.

[0058] Furthermore, each fixed base 57 is fixedly connected to a plurality of spherical bumps 573 distributed in a ring array at a position close to the air duct 574. The setting of the spherical bumps 573 can create a gap between the mask and one end of the air duct 574, thereby preventing the mask and the air duct 574 from being adsorbed too closely, resulting in a reduction in the air extraction range, thereby affecting the detection effect. The tops of the two micro air pumps 53 are commonly connected to a connecting rod 54; through the setting of the connecting rod 54, the vibrations of the two micro air pumps 53 can be kept synchronized, thereby avoiding differences in the degree of jitter of the two powder supply units.

[0059] As a further solution of the present invention, a connecting spring 502 is fixedly connected between the two output end tubes 5 and the extension hose 501, and a plurality of equally spaced paddles 503 are fixedly connected to each extension hose 501, and each paddle 503 is provided with a plurality of turbulence holes 504; through the above structure, when the extension hose 501 is displaced in the water due to the passage of strong airflow, it can drive the corresponding paddle 503 to move, thereby improving the stirring and mixing effect of the water; at the same time, when the paddle 503 moves, part of the water can generate turbulent flow at the turbulence hole 504, which is conducive to promoting the rapid dissolution of the absorbed pigment powder in the water, thereby facilitating the inspection personnel to observe and judge.

[0060] Furthermore, a plug hole 44 is provided at the center of the top of each of the multiple transparent tubes 4, and a plurality of air outlet holes 41 are provided on the top of each of the multiple transparent tubes 4 in a circular array with the plug hole 44 as the center. A wide-mouthed bucket 441 coaxially arranged with the plug hole 44 is fixedly installed on the inner side wall of the top of each transparent tube 4, and a limiting ring plate 42 is fixedly installed on one end of the outer wall of each transparent tube 4 near the top, and a plurality of levers 43 are fixedly connected to each limiting ring plate 42; the limiting ring plate 42 is used to control the installation of the transparent tube 4 To achieve the limiting effect, the set lever 43 is used to facilitate the inspection personnel to move the transparent tube 4; through the above structure, the multiple air outlet holes 41 are provided, which are conducive to the discharge of extracted air. Due to the washing effect of the water liquid, the discharged air is in a clean state, which can avoid pollution to the inspection site; the wide-mouthed bucket 441 is provided, and the diameter of the plug hole 44 and the open end of the wide-mouthed bucket 441 are larger than the diameter of the output end tube 5, so that the output end tube 5 is convenient to pass through the plug hole 44 and be inserted into the wide-mouthed bucket 441 for fixation.

[0061] As a further solution of the present invention, an extension plate 12 is fixedly connected to one side of the base plate 11, and two vertical plates 13 are fixedly connected between the extension plate 12 and the lower plate 21, and a support frame 22 is fixedly connected at the corners of the upper plate 2 and the lower plate 21; through the above structure, the upper plate 2 and the lower plate 21 are fixedly fixed by setting the vertical plates 13 and the support frame 22.

[0062] As a further solution of the present invention, a stepper motor 34 is fixedly installed on the side of the top outer wall of the bottom plate 11 close to the extension column 32, and the output shaft of the stepper motor 34 is fixedly connected to the driving gear 341, and one end of the circumferential outer wall of the extension column 32 is fixedly installed with a driven gear plate 31 that meshes with the driving gear 341; through the above structure, when performing a set of detection operations, an additional pair of corrugated hoses 52 and output end tubes 5 can be prepared, and the output end tubes 5 are also equipped with a pressure valve 51 and an extension hose 501, which are inserted into the temporary In the idle transparent tube 4, after completing a detection operation, the stepper motor 34 is operated, and the drive gear 341 and the driven gear plate 31 are used to drive the table 3 to rotate one hundred and eighty degrees, and the corrugated hose 52 is connected to the micro air pump 53, so that the next detection operation can be quickly connected. When the next detection operation is carried out, the inspection personnel can clean the used transparent tube 4 and the output end tube 5 in the transparent tube 4, and reinstall them on the table 3. Repeating the above steps can effectively improve the detection efficiency of the mask.

[0063] The specific method of use is: place the two masks to be tested on the fixed base 57, one of which can be rotated to be a standard mask in the market as a comparison standard, and the other is the mask to be tested. The specific fixing process of the mask is to first pull the negative pressure cone-mouth cylinder 56 away from the fixed base 57. After the mask is placed, the negative pressure cone-mouth cylinder 56 is pre-pressed against the mask under the reset action of the vibration spring 1 583. At this time, the fixing screw 581 is screwed and fixed with the internal thread end block 571 to complete the final fixation of the mask; start the two micro air pumps 53. Since the connecting carrier plate 1 582 and the connecting carrier plate 2 59 are connected by the vibration spring 1 583 and the vibration spring 2 591, the two micro air pumps 53 are in operation. 3 itself generates vibration, causing the vibration spring 1 583 and the vibration spring 2 591 to vibrate, and driving the two negative pressure cone-mouth cylinders 56 to vibrate, so that the powder supply unit in the negative pressure cone-mouth cylinder 56 also shakes synchronously, thereby shaking out the pigment powder, thereby simulating a dust environment; the micro air pump 53 allows air to pass through the mask on the subsequent fixed base 57. When dust passes through the mask, it is input into the transparent cylinder 4 through the output end tube 5 and dissolved in the water. Then, according to the degree of color change of the water in the transparent cylinder 4, the filtering and interception effect of the mask on dust is detected; the pressure valve 51 is set to increase the air pressure in the front half of the output end tube 5. When it is higher than the set value of the pressure valve 51, a pulse effect is formed, which causes the air to be fixed frequency from the extension The hose 501 bulges out, and the extended hose 501 is deformed more obviously due to the reaction force, and the water in the transparent tube 4 is stirred. At the same time, the better the breathability of the mask, the faster the air pressure in the output end tube 5 rises, the higher the opening frequency of the pressure valve 51 and the deformation frequency of the extended hose 501, and the inspectors use this to intuitively judge and compare the breathability of the mask; when the extended hose 501 is displaced in the water due to the strong airflow, the corresponding paddle 503 is driven to move, thereby improving the stirring and mixing effect of the water. At the same time, when the paddle 503 moves, part of the water flows rapidly at the turbulent hole 504, which is conducive to promoting the rapid dissolution of the absorbed pigment powder in the water, thereby facilitating the inspection of the inspectors. Observe and judge; when performing a set of inspection operations, an additional pair of corrugated hoses 52 and output end tubes 5 can be prepared. The output end tube 5 is also equipped with a pressure valve 51 and an extension hose 501, and inserted into the temporarily idle transparent tube 4. After completing a detection operation, the stepper motor 34 is operated, and the drive gear 341 and the driven gear disc 31 are driven to drive the table 3 to rotate one hundred and eighty degrees. The corrugated hose 52 is connected to the micro air pump 53, and the next inspection operation can be quickly connected. When the next inspection operation is carried out, the inspector can clean the used transparent tube 4 and the output end tube 5 in the transparent tube 4, and reinstall them on the table 3, and repeat the above steps to effectively improve the inspection efficiency of the mask.
