DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the embodiment of the present application more clear, the technical scheme in the embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] Please refer to Figures 2 to 6 The present application provides a technical scheme: a novel purging structure, comprising a quadrangular cylinder 1, the four side surfaces of the quadrangular cylinder 1 are embedded with glass windows 101, one end of the quadrangular cylinder 1 is detachably connected with an air supply box 3, the air supply box 3 comprises a box body 301, the bottom surface of the box body 301 is integrally provided with a windshield 302 inside the quadrangular cylinder 1, an annular air supply cavity 303 is formed in the box body 301, air outlets 304 are formed in the periphery of the windshield 302 corresponding to the positions of each glass window 101, each air outlet 304 is in communication with the annular air supply cavity 303, two air inlets 305 are formed in the top surface of the box body 301, and the two air inlets 305 are in communication with the annular air supply cavity 303.
[0026] Please refer to Figures 2 to 4 The wind shield 302 is a lower-small and upper-large conical structure and its shape is consistent with the cross-sectional shape of the square tube 1. The outer wall of the top circle of the wind shield 302 is attached to the inner wall of the glass window 101.
[0027] By setting the wind shield 302 at the bottom end of the box body 301, the diffusion of the airflow inside the square tube 1 can be reduced, and the airflow can be efficiently swept over the glass surface in a limited space.
[0028] Further, all the air outlets 304 are arranged on the four side walls of the wind shield 302, and each air outlet 304 is provided with an inclined angle corresponding to the glass window 101 on one side.
[0029] By setting the air outlet 304 with an inclined angle, the airflow can be more efficiently swept over the surface of the glass window 101.
[0030] Further, the area of one end of each air outlet 304 communicated with the annular air supply cavity 303 is larger than that of the other end.
[0031] The area of the end of the air outlet 304 close to the glass window 101 is small, so that the airflow speed can be increased during the process of the airflow in the annular air supply cavity 303 entering the air outlet 304 and being discharged, thereby further improving the sweeping efficiency.
[0032] Further, a plurality of assembly holes 306 are arranged on the top surface of the box body 301.
[0033] When connecting the air supply box 3 and the square tube 1, the two can be installed together by inserting bolts in the assembly holes 306, thereby improving the convenience in the disassembly process and improving the applicable scenarios.
[0034] Further, the outer wall of each air inlet 305 is provided with a thread, and a multi-stage purification mechanism 4 is detachably connected through the thread.
[0035] By connecting the multi-stage purification mechanism 4 between each air inlet 305 and the air supply device, the purity of the airflow entering the air supply box 3 can be further purified, thereby avoiding the influence of dust on the sweeping efficiency of the sweeping gas.
[0036] Further, each multi-stage purification mechanism 4 includes a connecting pipe 401, a plurality of 402 fixedly connected between the inner walls of the connecting pipe 401 are distributed along the extension direction of the connecting pipe 401, and a self-cleaning structure is further arranged in the connecting pipe 401.
[0037] By setting several filter screens 402 inside the connecting pipe 401, the airflow input to the air supply box 3 by the air supply device can be filtered and purified, reducing the dust carried in the purge airflow to relatively improve the purging efficiency. At the same time, through the self-cleaning structure, each filter screen 402 can be brushed by the airflow driving to avoid blockage of the filter screen 402 and reduce the air supply efficiency.
[0038] Further, the self-cleaning structure includes a rotating shaft 403 rotatably installed in the mounting ring arranged in the middle of the several filter screens 402. A gas-driven impeller 404 is fixedly sleeved on the end of the rotating shaft 403 away from the air inlet 305. A plurality of groups of scraper plates 405 corresponding to the filter screens 402 are arranged on the outer wall of the rotating shaft 403. Each group of scraper plates 405 is located above the corresponding filter screen 402 and has a brush 406 arranged on the side surface thereof facing the filter screen 402.
[0039] When the airflow passes through the gas-driven impeller 404, the rotating shaft 403 will rotate independently relative to all the filter screens 402. When the rotating shaft 403 rotates, the plurality of groups of scraper plates 405 on the outer wall thereof will also rotate synchronously, so that the brush 406 arranged on one side surface of each scraper plate 405 brushes the corresponding filter screen 402, thereby ensuring the airflow passing efficiency.
[0040] Further, the inner wall of the bottom end of each connecting pipe 401 is provided with an inner thread groove 407 corresponding in thread to the outer wall of the air inlet 305. The outer wall of the top end of each connecting pipe 401 is provided with an outer thread 408 for connecting with the air supply device.
[0041] The multi-stage purification mechanism 4 is detachably connected to the air supply box 3 and the external air supply device by a threaded manner, thereby improving the convenience during the assembly and disassembly process, facilitating the assembly, disassembly and replacement.
[0042] Working principle: the air supply box 3 is connected to the four-square cylinder 1 by bolts. At this time, the wind shield 302 is located inside the four-square cylinder 1 and the outer wall thereof is attached to the inner wall of the four-square cylinder 1 to reduce the airflow diffusion. The multi-stage purification mechanism 4 is installed on each air inlet 305. The gas inlet of the external air supply device is connected to the other end of the multi-stage purification mechanism 4. The external air supply device supplies air to the annular air supply cavity 303. The airflow drives the rotating shaft 403 to rotate after entering the connecting pipe 401. The plurality of groups of scraper plates 405 arranged on the outer wall of the rotating shaft 403 brush each filter screen 402 to avoid blockage and reduce the air supply effect. After the airflow enters the annular air supply cavity 303 through the connecting pipe 401, it enters each air outlet 304 through the annular air supply cavity 303, respectively. The airflow output from the air outlet 304 blows the corresponding side of the glass window 101, thereby reducing the dust adhered to the glass window 101 and affecting the clarity of the high-speed camera shooting.
[0043] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
