[Prior Art] With the development of science and technology, the air quality is becoming more and more harmful to the human body. * The daily micro-source (staining, and & one control: killing), transmission route and Protective measures. Among them, the use of protective gears, such as masks, protective clothing, and (4) applications, the development of masks using more porous fabrics to make the fabric after the = = detection, to obtain According to the efficiency test (four), the detection of the rate of the device is to develop a device for the winter. In general, the test device uses a test solution that uses aerosol generation and tests == for example bacteria to atomize the test. The mist is used to carry out the action of the filter material (such as a fabric such as a mask) that is to be tested by the mist. Then, the sampler is used to receive the filtered magnetic permeability. The level-following-like detection device is mainly placed in Weng's..., the aerosol chamber, and the aerosol generator is installed in the aerosol chamber sampler at the lower end of the aerosol chamber. Through the filter material, the test is carried out. However, the gas mist generator, I., and the child completely atomize the test liquid into the test gas mist, and the test liquid that is not atomized will form a liquid droplet 'drop directly on the cross material. The disadvantage of affecting the detection result due to the covering effect In addition, before entering the actual detection stage, the detection device must first pass through the pre-preparation phase. In the preparation phase, the crossing material is not placed in the detection device, and the detection device begins to generate the test aerosol first. And after testing the particle size of the aerosol particles to meet the requirements of the test conditions, the filter material is placed in the detection device. Therefore, the detection device must be disassembled and reassembled, which greatly reduces the convenience of operation. When, _ need to repeatedly disassemble the detection device, these disassembly and assembly operations will easily change the detection conditions. This increases the variability of the detection conditions, greatly reducing the stability of the detection and then in the process of disassembling the detection device The invention further increases the chances of the components in the detecting device and the filter material being externally contaminated. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a detecting device and a detecting method which utilize the test gas mist respectively from the top of the buffer bottle. The inlet and the outlet of the buffered β bottle enter and leave the buffer bottle, so that the test aerosol enters the buffer bottle. According to the above object of the present invention, a cleaning device comprising a buffer bottle, an atomizer, an aerosol chamber and a sampler is provided. The buffer bottle has a The material inlet and the discharge port are respectively used to make a test aerosol enter and leave the buffer bottle, and are respectively located at the top and the side of the buffer bottle. The atomizer is disposed at the feed port for using a test liquid mist. The test chamber is provided with an upper end opening and a lower end opening, and the test aerosol leaving the buffer bottle enters the aerosol chamber from the upper end opening. The sampler is connected to the aerosol chamber via the lower end opening, and is received by 201028677. The test aerosol after filtering is used to test the filtration efficiency of the filter material, and the filter material is disposed between the aerosol chamber and the sampler. According to another object of the present invention, a detection method is proposed. First, a test aerosol is provided. Enter a buffer bottle along a feed direction. Secondly, the pilot test aerosol exits the buffer bottle from a discharge direction. The feed direction is non-parallel to the discharge direction. Again, the dispersion test aerosol is in an aerosol chamber. Next, the test aerosol was filtered. The filtered test aerosol is then received to detect filtration efficiency. Φ The detecting device and the detecting method of the invention use the test gas mist to enter the buffer bottle in a direction non-parallel to the direction in which the test gas mist leaves the buffer bottle, and the buffering function is generated by the buffer bottle, so that the test gas leaving the buffer bottle is stable. The flow rate and uniform average particle size improve handling convenience, improve detection stability, and avoid contamination of the filter material. [Embodiment] A detecting device and a detecting method according to a preferred embodiment of the present invention are used to detect the filtering efficiency of a filter medium. The detecting device uses the feeding port and the discharging port of the buffer bottle to be staggered, so that the aerosol particles exceeding the particle size range of the detection condition and the test liquid not atomized are not directly dripped to the ferry material. The role of buffering. It has the advantages of improved operation convenience, improved detection stability, and avoiding contamination of the filter material. «With reference to Fig. 1, a schematic view of a detecting device not according to a preferred embodiment of the present invention is shown. The detecting device 100 of this embodiment mainly comprises a buffer bottle 110, an atomizer 120, an aerosol chamber 140 and a sampler 15A. The buffer bottle 110 has a feed port 11a and a discharge port 11b, respectively located at the top and side of the 201028677 buffer bottle 110. A test aerosol S enters the buffer bottle 110' from the feed port 110a. The buffer bottle no is left from the discharge port 110b. The atomizer 120 is disposed at the inlet port 110a for atomizing a test liquid into the test gas mist S. The test mist S of the aerosol chamber 140 having an upper end opening 140a and a lower end opening 140b' exiting the buffer bottle 110 is introduced into the aerosol chamber 140 from the upper end opening i4〇a. In this embodiment, the distance between the discharge port 11b and the bottom of the buffer bottle 11b is greater than the distance between the discharge port 110b and the top end of the buffer bottle 11〇. The sampler 150 is connected to the aerosol chamber 140 via the lower end opening 140b for receiving the filtered test gas mist S filtered by a filter material F disposed between the aerosol chamber 140 and the sampler 150, thereby verifying the filtration efficiency of the filter material F. . The detecting device 1 uses the feed port 11〇a and the discharge port ii〇b which are staggered, so that the buffer bottle no can generate a buffering effect, and the test aerosol S particles exceeding the particle size range of the detection condition are not The atomized test solution does not drip directly on the filter material ρ' to avoid contamination of the filter material F and affect the detection result. Further, the buffer bottle 110 and the aerosol chamber 140 have a longitudinal direction L1 and L2, respectively. The long axis direction L1 of the buffer bottle 11〇 and the long axis direction L2 of the aerosol chamber 140 are respectively substantially perpendicular to a horizontal plane, and the long axis direction L1 of the buffer bottle ❹ 11〇 is preferably substantially parallel to the aerosol chamber 14 Long axis direction L2. In accordance with a preferred embodiment of the present invention, the feed port 11a of the buffer bottle 11() and the upper end opening 140a of the aerosol chamber 140 are located in different major axis directions. This configuration ensures that the test aerosol S enters the buffer bottle 110 from the feed port 11 〇a and does not enter the aerosol chamber 140 directly through the upper end opening 14〇a. On the other hand, the detecting device 100 further includes a connecting tube 13 设置 disposed between the buffer bottle 110 and the aerosol chamber 140. According to a preferred embodiment of the present invention, in the embodiment of 201028677, the connecting pipe 130 is perpendicular to the side of the buffer bottle 11, i.e., perpendicular to the long axis direction of the buffer bottle 110, as shown in Fig. 1. The two ends of the connecting pipe 130 are respectively connected to the discharge raft and the upper end opening. The test aerosol s leaving the buffer bottle 110 from the discharge port u〇b is guided to the aerosol chamber 140 via the connecting tube 13A. In addition, in various embodiments, the connecting tube 130 may also be non-perpendicular to the side lu of the buffer bottle 11〇. Referring to Figure 2, there is shown a schematic view of a buffer bottle and a connecting tube of a detecting device in accordance with another preferred embodiment of the present invention. The connecting pipe 13〇' is connected to the discharge of the buffer bottle 11〇, at the port 11〇b, still at the connecting pipe 13〇, and is connected to the upper end opening 140a of the aerosol chamber 140. That is, the connecting pipe 13〇 is inclined toward the bottom of the buffer bottle 11〇. In addition, the detecting device 100 further includes a vacuum pump 160, an air pump 170, and a syringe pump 180. The vacuum pump 160 is configured to provide a flow of air through the buffer bottle 110, the aerosol chamber 14A, and the sampler 15A to drive the test aerosol S. In the present embodiment, the vacuum pump ι 60 is disposed at the downstream end of the sampler 15 by air pumping so that the air flow sequentially passes through the buffer bottle 110, the aerosol _ face and the sampler 150. The atomizer 120 of the present embodiment is, for example, a gas-type aerosol generator. The air pump 170 and the syringe pump 180 respectively supply a high gas and a test liquid to the atomizer 120. The atomizer 120 uses the high pressure gas supplied from the air pump 170 to atomize the test liquid into minute particles. The detecting device 100 can, for example, apply the detection of the filtering efficiency in accordance with a preferred embodiment of the present invention. The following is a description of the detection method according to the present invention to the preferred embodiment. Referring to Figure 3, a flow chart of a method of detecting in accordance with a preferred embodiment of the present invention is shown. The detecting method of the embodiment first performs step S1 to provide the test aerosol S to enter the buffer bottle 11 along a direction D1 of feed 201028677. Next, the test mist S is separated from the discharge direction m by step t2, and the guide is shown. The test m is not parallel to the discharge direction bottle, 0, wherein the feed direction feed port ma enters along the feed direction D1! ^1 towel 'test aerosol s is exited from the buffer leaf by the port 110b along the discharge direction D2. Ke Qiang 4 11〇. The feed direction di is substantially perpendicular to the discharge direction D2. As shown in Fig. 1, the ant is driven by the airflow, and the connection pipe 130 can be tilted toward the bottom of the buffer bottle 110, as shown in Fig. 2.螬·Show. That is, the side 111 of the buffer bottle 110 corresponds to the portion ' between the discharge port 11b and the bottom of the buffer bottle 110' and the discharge direction D2 has an acute angle Θ. Next, the detecting method performs the step of dispersing the test aerosol S so that the particles of the test gas mist S are uniformly dispersed in the aerosol chamber 140 as shown in step S3. Then, as shown in steps S4 and S5, the test aerosol S is filtered, and the filtered test aerosol S is received, thereby detecting the filtration efficiency. The detecting method of this embodiment may further comprise the steps of atomizing the test liquid, supplying the gas stream, and separating the test gas mist S and the un-atomized test liquid. In practical application, the test liquid is atomized into the test gas mist S by the atomizer 120, and the air flow is provided by the vacuum pump 160, and the test gas mist S is sequentially driven by the air flow to pass through the buffer bottle 110, the connecting tube 130, and the aerosol chamber. 140, filter material F and sampler 150. Since the flow of a specific flow rate can drive particles of a specific particle size range, the test aerosol s particle system exceeding the particle size of this range cannot be driven by the gas flow. Further, since the discharge port is closer to the top end of the buffer bottle 110, the aforementioned test aerosol s particles which cannot be driven by the air flow settle to the bottom of the buffer bottle 110 in the direction of gravity. In addition, the test liquid which has not been atomized is also directly dropped from the feed port 11a to the bottom of the buffer bottle 110. In this way, the test aerosol particles s particles of the test conditions and the test liquid droplets that have not been atomized are separated. Further, in the preparation stage for performing the detection and the actual detection stage, the test aerosol S which does not meet the detection conditions and the test liquid droplets which are not atomized are dropped to the bottom of the buffer bottle 110. In practical application, by the setting of the buffer bottle 110, when the flow rate of the airflow and the particle size of the test aerosol are corrected in the pre-preparation stage, the droplet contamination sampler 150 and the re-disassembly detection device can be avoided. The embarrassing action greatly enhances the convenience of operation and the efficiency of detection. In the spring, the detection device 100 of the present embodiment was subjected to a test of bacterial filtration efficiency (Bacteriai Fiitrati〇n Efficiency, BFE) using the American Society for Testing and Materials (ASTM) F2101 standard test method. The test solution contains bacteria, such as Staphylococcus aureus, and the atomizer 12 atomizes the test liquid into a test aerosol S containing bacteria, and the filter material ρ is a medical mask. The conditions of the standard test were as follows: the flow rate of the gas supplied by the vacuum pump 16 was 28.3 L/min'. The average particle diameter of the test aerosol S particles was 2.7 to 3 3 μm, and the total number of colonies was between 1700 and 2700. The following description will be made on the method of applying the aforementioned conditional examination, and the bacterial transition efficiency of the medical mask is obtained by comparing the amounts of bacteria before and after filtration. First, the difference in the number and particle size of the test aerosol provided by the detection device with/without buffer bottle will be described. In the following, the same person is tested with or without a buffer bottle, and 82 sets of buffered data and 4 sets of unbuffered data are obtained. The test results are shown in Table j. -Test gas 201028677 Mean standard deviation Mean standard deviation Buffer bottle 2196 273 2.89 0.11 Buffer bottle 2168 365 2.95 —----. 0.16 Table 1 According to the test results, the data of 82 groups of buffer bottles are all in the standard. The test method specifies the number and particle size range of the test aerosol particles; while the data of the unbuffered bottles, only 17 groups fall within the range of the number and particle size of the aerosol particles specified by the standard test method. In addition, the standard deviation of the data of the buffered bottle is smaller than the standard deviation of the data of the unbuffered bottle. It is shown that the detecting device containing the buffer bottle can stably generate the test aerosol of a specific particle size and quantity according to the flow rate of the airflow, thereby effectively improving the detection and filtering efficiency. Effectiveness. Next, please refer to Figure 4, which shows the distribution of the number and particle size of the test aerosol particles. Curves A and B show the number of test aerosol particles and the particle size distribution curve provided by the detection device with buffer bottles and unbuffered bottles, respectively. As can be seen from Fig. 4, the detection device with the buffer bottle does not significantly change the particle size distribution of the test aerosol particles', so it can be fully applied to ASTM F2101 or other standard test methods. On the other hand, in the following, the detection device 1 of the present embodiment is compared with the conventional detection device for the bacterial filtration efficiency detection capability. Among them, a medical mask was used as a filter to filter, and five sets of filtration efficiency values were obtained, and the test results were shown in Table 2. The detection device of the detection device of the present embodiment tests the average number of bacterial colonies of the aerosol 2464 CFU/mL 2640 CFU/mL test aerosol particle size 3.0 micron 3.3 micron 11 201028677 first bacterial transition efficiency 97.6% 99.6% ~ second Secondary bacteria over-yield efficiency 97.1% 98.9% Second bacterial filtration efficiency 97.6% 99.5% ~~~ Fourth bacterial filtration efficiency---------- 97.5% 99.5% ^, fifth bacterial filtration efficiency 97.8% 98.9% Average bacterial filtration efficiency ~~ 97.5% 99.3% Standard deviation~~~ 0.26 0.35 ~ Z-Scores 0.9 ------^ 0·9 ❿ Table 2 Test aerosol s provided by the detection device 100, The average number of colonies was 2464 and the average particle size was 3 〇 microns. As is apparent from Table 2, the average filtration efficiency of the detecting device 1 of the present embodiment was 97 5%, and the standard deviation was 〇·26. The Z value (Z-Sc〇res) analysis was carried out according to the ASTM D6674 standard to obtain a z value of 〇 9. In the z-value analysis, the absolute value of the B value is less than 2, indicating that the detection ability is good (satisfact〇ry). The detecting apparatus 100 and the conventional detecting apparatus according to the preferred embodiment of the present invention have a Z value of 0.9'. Therefore, it is known from the results that the detecting apparatus 100 can provide a detecting capability similar to that of the conventional detecting apparatus. That is to say, when the detecting means i 〇〇 uses the buffer bottle 110 for the buffering operation, the detecting ability of the detecting device 100 for the filter material transition efficiency is not changed. The detecting device and the detecting method according to a preferred embodiment of the present invention are arranged to provide a buffer bottle between the atomizer and the aerosol chamber. The feed port and the discharge port of the buffer bottle are staggered, and the feeding direction is not parallel to the discharge direction, so that the particle size in the test gas is too large, the particles cannot be driven by the air flow, and the mist is not atomized. The test liquid droplets are dripped into the buffer bottle 12 201028677 The original droplets are directly dripped on the filter material F, resulting in the disadvantage of covering the detection result of the filtration efficiency of $%. In addition, this application relies on the far-distance 2-line buffering method, which completely utilizes the airflow to drive the test gas mist. The nozzle enters the aerosol chamber to eliminate the influence of gravity and sedimentation, so that the test aerosol reaching the aerosol chamber meets the test. The conditions of demand can increase the stability of the test. In addition, the use of buffer bottles for buffering eliminates the need for traditional inspections to require repeated disassembly and assembly between the preparation and testing phases, resulting in external contamination and variations in detection conditions, further improving the convenience of operation. Sex and the reliability of the test results. The present invention has been disclosed in the above embodiments, and is not intended to limit the present invention.
