DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As attached Figure 1-4 A novel porous smoke-generating tube device is shown, comprising a delivery bellows 2 connected to the mist outlet end of a water mist generator 1, and a flue pipe 3 is arranged at one end of the delivery bellows 2.

[0021] Specifically, in this structure, the water mist generator 1 can generate water mist, so that the water mist is transported through the transport bellows 2 and discharged through multiple smoke outlets 8 at the flue pipe 3, which can be used to test the airflow pattern in the clean room environment, and the air flow path can be clearly seen, realizing visual air flow detection;

[0022] The water mist generator 1 is an existing device on the market, and its working principle is the existing technology, which will not be introduced in detail in this application.

[0023] In a specific embodiment, as shown in the attached Figure 1 , 2As shown in FIG. 3 , an adjustable smoke outlet structure is provided on the surface of the flue pipe 3, and the adjustable smoke outlet structure includes a plurality of movable plates 4. A rectangular groove 5 is provided on the surface of the flue pipe 3, and the plurality of movable plates 4 are embedded in the interior of the rectangular groove 5. Fixed plates 6 are provided on both inner walls of the rectangular groove 5. An accordion-type shielding cover 7 is installed between the fixed plate 6 and the movable plate 4 and between each two adjacent movable plates 4. A smoke outlet 8 is provided on the surface of the movable plate 4. Slide grooves 9 are provided on the top and bottom of the inner cavity of the rectangular groove 5 opened by the flue pipe 3. The top and bottom of the movable plate 4 are embedded in the interior of the slide groove 9 and are slidably connected in the interior of the slide groove 9. Toggle grooves 10 are provided on the surface of the movable plate 4 on both sides of the smoke outlet 8. The two ends of the plurality of accordion-type shielding covers 7 are respectively connected to between the fixed plate 6 and the movable plate 4 and between the two movable plates 4. The accordion-type shielding cover 7 and the movable plate 4 are adapted to the size of the rectangular groove 5.

[0024] Specifically, in this structure, when the water mist is transported through the flue pipe 3, it can be discharged through the smoke outlets 8 at the multiple movable plates 4, which can make the smoke discharge more uniform, the airflow pattern test clearer, and avoid the smoke being too concentrated and unable to clearly judge the flow direction of the airflow;

[0025] The operator can adjust the spacing between the multiple smoke outlets 8 according to the actual situation, so that the airflow test effect is better. Specifically, the operator uses the toggle slot 10 on the movable plate 4 to forcefully toggle the movable plate 4 so that the movable plate 4 slides left and right inside the rectangular slot 5. The sliding between the multiple movable plates 4 can further adjust the spacing between the multiple smoke outlets 8. At the same time, during the process of adjusting the multiple movable plates 4 left and right, the accordion-type shielding cover 7 can achieve the effect of expansion and contraction, ensuring that when the movable plate 4 is adjusted left and right, the water mist inside the flue pipe 3 will be discharged from the flue port opened by the movable plate 4, thereby improving the use effect.

[0026] It is worth mentioning that when the movable plate 4 is inside the rectangular groove 5, the operator needs to push the movable plate 4 forcefully to achieve the left and right adjustment of the movable plate 4. Under normal circumstances, the movable plate 4 will not move inside the rectangular groove 5, and the accordion-type shielding cover 7 is an accordion-type structure, which can achieve the effect of expansion and contraction, and has a good sealing effect with the rectangular groove 5 at the flue pipe 3. The water mist inside the flue pipe 3 will not overflow from the accordion-type shielding cover 7 through the rectangular groove 5, ensuring that the water mist inside the flue pipe 3 is always discharged at the smoke outlet 8 opened by the movable plate 4.

[0027] In a specific embodiment, as shown in the attached Figure 1 , 2As shown in , 4, an outer connecting ring 11 is provided between the conveying bellows 2 and the flue pipe 3, and an inner connecting ring 12 is provided at one end of the flue pipe 3. The outer diameter of the inner connecting ring 12 is smaller than the inner diameter of the outer connecting ring 11, an inner thread groove 13 is provided on the inner wall of the outer connecting ring 11, and an outer thread groove 14 is provided on the outer wall of the inner connecting ring 12. The outer connecting ring 11 and the inner connecting ring 12 are threadedly connected via the inner thread groove 13 and the outer thread groove 14, a filter net 15 is provided inside the outer connecting ring 11, and an activated carbon adsorption net 16 is provided on one side of the filter net 15.

[0028] Specifically, in this structure, one end of the flue pipe 3 can be threadedly connected to the delivery bellows 2 by connecting the inner ring 12 and the outer ring 11, and can be easily dismantled. The inner part of the outer ring 11 is equipped with a filter 15 and an activated carbon adsorption net 16, which can adsorb particulate matter or bacteria in the water mist, ensuring that the water mist will not affect the test environment when it is discharged;

[0029] After the connecting outer ring 11 and the connecting inner ring 12 are disassembled through threads, it is convenient for operators to clean the filter screen 15 and the activated carbon adsorption screen 16 inside the connecting outer ring 11.

[0030] Working principle of this utility model:

[0031] Specifically, when the above structure is used, first, the operator connects the outer connection ring 11 and the inner connection ring 12 to achieve the connection between the flue pipe 3 and the conveying bellows 2;

[0032] The water mist generated by the smoke generator is transported through the conveying bellows 2 and the flue pipe 3, and discharged through the flue openings on the surface of the multiple movable plates 4, so that the smoke is discharged more evenly, and the air flow path can be clearly seen, and visual air flow detection can be achieved to avoid excessive concentration of smoke and inability to clearly judge the direction of the airflow;

[0033] According to the actual situation, the operator forcibly moves the movable plate 4 through the toggle groove 10 on the movable plate 4, so that the movable plate 4 slides left and right inside the rectangular groove 5. The sliding between the multiple movable plates 4 can adjust the spacing between the multiple smoke outlets 8. At the same time, during the process of adjusting the multiple movable plates 4 left and right, the accordion-type shielding cover 7 can achieve the effect of expansion and contraction. The accordion-type shielding cover 7 shields the water mist inside the flue pipe 3, ensuring that when the movable plate 4 is adjusted left and right, the water mist inside the flue pipe 3 will be discharged from the flue outlet opened by the movable plate 4, thereby improving the use effect;

[0034] Moreover, in the process of conveying water mist, a filter screen 15 and an activated carbon adsorption screen 16 are installed inside the connecting outer ring 11, which can adsorb particulate matter or bacteria in the water mist to ensure that the water mist will not affect the test environment when it is discharged. After the connecting outer ring 11 and the connecting inner ring 12 are disassembled through threads, it is convenient for the operator to clean the filter screen 15 and the activated carbon adsorption screen 16 inside the connecting outer ring 11.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
