Description

Technical Field

[0001] This invention relates to the field of gas detection technology, and more specifically, to a detection device for the preparation of electronic mixed gases. Background Technology

[0002] Electronic mixed gases refer to gases containing two or more effective components, or gases containing non-effective components but whose content exceeds the specified limit. Examples include thermal oxidizing mixed gases, such as mixtures of oxygen with nitrogen or argon, which are used in semiconductor manufacturing to form an oxide layer on the surface of silicon wafers and have important applications in the insulation and isolation of integrated circuits. There are also diffusion mixed gases, which are mixtures of carrier gases (such as argon or nitrogen) with gases that have diffusion effects (such as borane or phosphine). All of these are electronic mixed gases, and such gases can be detected by gas detection equipment.

[0003] A search revealed that patent CN109752506A discloses a combustible gas detector, comprising a housing, a suction pipe fixed at the front end of the housing, and a display screen. A vacuum pump is installed inside the housing, and the suction pipe is connected to the vacuum pump. A detection module is installed between the vacuum pump and the suction pipe, and the detection module is electrically connected to the display screen. A mounting groove is formed on the housing, with a cross-sectional area larger than the display screen area to accommodate it. The display screen is mounted at the opening of the mounting groove. The end of the display screen facing the front end of the housing is hinged to the housing, while the end facing the rear end of the housing is a free end. A drive mechanism is installed inside the mounting groove to pull the display screen inwards. This invention has the advantage of allowing for convenient and rapid reading of the numbers on the display screen even in environments with high light intensity, such as outdoors.

[0004] Regarding the aforementioned technologies, existing fixed detection equipment requires connecting a gas-carrying pipe to a connector on the detection equipment during use, and then disconnecting it after the detection is completed. However, when the connection is removed after detection and repeated detection is performed, the previously tested connector, after coming into contact with a certain gas, may retain the characteristics of that gas to a certain extent or affect the subsequent adsorption, diffusion, and other behaviors of the gas, which may affect subsequent detection. At the same time, other dust and impurities adhering to the connector during connection may also affect subsequent detection. Therefore, a detection device for the preparation of electronic mixed gases is proposed. Summary of the Invention

[0010] Furthermore, the transmission assembly includes a worm gear fixedly connected to the outer surface of the long rod, and a worm is rotatably connected between the front end face and the rear end face of the inner wall of the L-shaped box, with the outer surface of the worm meshing with the outer surface of the worm gear.

[0011] Furthermore, the transmission assembly also includes two transmission rollers that are respectively fixedly connected to the outer surfaces of the worm and the rotating column, and a transmission belt is drivingly connected between the outer surfaces of the two transmission rollers.

[0012] Furthermore, the directional limiting component includes a wheel fixedly connected to the lower part of the outer surface of the long rod.

[0021] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0022] Please see Figure 1-8 A detection device for preparing electronic mixed gases includes a main module 100 and a conversion module 200. The main module 100 includes a detection instrument body 110, with a test tube 130 connected to the bottom of the detection instrument body 110. An L-shaped box 120 is fixedly connected between the bottom and one side of the detection instrument body 110. The conversion module 200 includes a long rod 210 rotatably connected to the top of the inner wall of the L-shaped box 120. The bottom end of the long rod 210 extends to the bottom of the L-shaped box 120 and is fixedly connected to a conversion module. The inside of the conversion disc 220 is arranged in a ring with multiple connectors 240 at equal intervals. The inside of the L-shaped box 120 is provided with a transmission component 250 connected to the long rod 210. The bottom of the main body 110 of the testing instrument is provided with a connecting component 260 connected to one of the connectors 240 and the test tube 130. The front end of the L-shaped box 120 is provided with a rotating component 270 connected to the connecting component 260. One side of the L-shaped box 120 is provided with a limiting component 280 connected to the outer surface of the long rod 210.

[0023] In use, the pipe carrying the gas to be tested is connected to one of the connectors 240. The gas enters the main body 110 of the testing instrument through the connector 240 and the test tube 130 for testing. After the test is completed, the pipe is separated from the connector 240. When it is necessary to connect the next pipe, the operator first presses the rotating component 270, so that the connecting component 260 is separated from one of the connectors 240 and the test tube 130. After separation, the rotating component 270 is rotated. The rotating component 270 will drive the transmission component 250, which will drive the long rod 210 and the conversion disk 220 to rotate. After the limiting component 280 makes a sound, the rotating component 270 stops rotating. At this time, the other connector 240 will move to the bottom of the test tube 130. The rotating component 270 is restored and locked, so that the connecting component 260 seals the other connector 240 and the test tube 130, ensuring the subsequent gas flow and making the connector 240 easy to switch, preventing a significant impact on subsequent tests.

[0024] The connecting assembly 260 includes two slide rails 261 fixedly connected to the bottom of the main body 110 of the testing instrument. Sliding blocks 262 are slidably connected inside each slide rail 261. Connecting arms 263 are hinged to the front ends of each sliding block 262. A steering rod 264 is fixedly connected to the bottom of each sliding block 262. A sealing arc plate 265 is fixedly connected to one end of each steering rod 264. The inner walls of the two sealing arc plates 265 are in contact with the outer surfaces of the test tube 130 and one of the connectors 240. The two ends of the two sealing arc plates 265 are in contact with each other, and adjacent sides of the two sealing arc plates 265 are fixedly connected. The fixed connection has two sealing strips 266. The main module 100 also includes multiple annular sealing grooves 140, which are respectively opened on the outer surface of multiple connectors 240 and one of the test tubes 130. Two sealing arc plates 265 are respectively movably snapped into the interior of two of the annular sealing grooves 140. The rotating assembly 270 includes a rotating column 271 rotatably connected to the front end face of the L-shaped box 120. A movable square bar 272 is rotatably connected inside the rotating column 271. A center connecting block 274 is rotatably connected to the rear end face of the movable square bar 272. The outer surface of the movable square bar 272 is connected to the rotating... A first spring 273 is fixedly connected between the front ends of the column 271. A control handle 275 is provided on the front end of the movable square bar 272. One end of each of the two connecting arms 263 is hinged to the central connecting block 274. The rotating assembly 270 also includes an inner hollow slot box 276 fixedly connected to the front end of the L-shaped box 120. An L-shaped metal bar 277 is movably connected inside the inner hollow slot box 276. A slot is provided on the outer surface of the movable square bar 272. A second magnetic block 279 is fixedly connected inside the slot. One end of the L-shaped metal bar 277 is movably connected inside the slot and magnetically connected to the second magnetic block 279. The other end of the L-shaped metal strip 277 extends to the outside of the hollow slot box 276. The inner cavity of the hollow slot box 276 is fixedly connected to the first magnetic block 278. The transmission assembly 250 includes a worm gear 251 fixedly connected to the outer surface of the long rod 210. A worm 252 is rotatably connected between the front end face and the rear end face of the inner wall of the L-shaped box 120. The outer surface of the worm 252 meshes with the outer surface of the worm gear 251. The transmission assembly 250 also includes two transmission rollers 253 fixedly connected to the outer surfaces of the worm 252 and the rotating column 271, respectively. A transmission belt 254 is connected between the outer surfaces of the two transmission rollers 253.

[0025] The operator moves the L-shaped metal strip 277 out of the slot and separates it from the second magnetic block 279. At this time, the L-shaped metal strip 277 is connected to the first magnetic block 278. Subsequently, by pressing the movable square strip 272 with the control handle 275, the first spring 273 will contract, and the center connecting block 274 will push the two connecting arms 263. The connecting arms 263 will drive the two sliders 262 to move in opposite directions, causing the two sealing arc plates 265 to move away from each other, and the sealing strip 266 to retract from the annular sealing groove 140. Then, by rotating the movable square strip 272 with the control handle 275, the rotating column 271 will be rotated. When the rotating column 271 rotates, it will drive the worm gear 252 through the transmission belt 254. The worm gear 252 will drive the worm wheel 251 to drive the long rod 210 to rotate. The long rod 210 drives the conversion disc 220 and connector 240 to rotate. When the other connector 240 moves to the bottom of the test tube 130, the control handle 275 is released to allow the first spring 273 to push the movable square bar 272 to reset, so that the two sealing arc plates 265 come close to each other and fit against the outer surface of the test tube 130 and the other connector 240. The sealing strip 266 will also be inserted into the annular sealing groove 140 to improve the sealing performance of the connection. At this time, the L-shaped metal strip 277 is then moved to insert into the slot and magnetically connected to the second magnetic block 279, which locks the state of the movable square bar 272, thereby locking and maintaining the state of the two sealing arc plates 265 and the sealing strip 266, ensuring the subsequent gas sealing and flow, and making it easy to switch the connector 240.

[0026] The directional control assembly 280 includes a wheel 281 fixedly connected to the lower part of the outer surface of the long rod 210. The outer surface of the wheel 281 is provided with a plurality of one-way ratchet grooves 282. A hollow block 283 is fixedly connected to one side of the L-shaped box 120. A one-way ratchet 284 is movably connected inside the hollow block 283. One end of the one-way ratchet 284 is movably connected to the inside of one of the one-way ratchet grooves 282. A second spring 285 is fixedly connected between the other end of the one-way ratchet 284 and the inner wall of the hollow block 283. The number of one-way ratchet grooves 282 is the same as the number of connectors 240, and the positions of the one-way ratchet grooves 282 and the connectors 240 correspond to each other.

[0027] When the long rod 210 rotates, the one-way ratchet 284 will move out of one of the one-way ratchet grooves 282. When the other joint 240 moves to the bottom of the test tube 130, the one-way ratchet 284 will be pushed into the other one-way ratchet groove 282 by the second spring 285 and make a sound. After the sound is made, the operator stops rotating the control handle 275.

[0028] The conversion module 200 also includes multiple clamping plates 230 that are fixedly connected to the outer surfaces of multiple connectors 240. Multiple mounting slots are provided on the outer surface of the conversion disk 220. The multiple clamping plates 230 are movably engaged in the interior of the multiple mounting slots. Multiple mounting bolts 150 are threadedly connected to the top of the conversion disk 220. The multiple mounting bolts 150 extend into the interior of the multiple clamping plates 230.

[0029] The connector 240 is installed using mounting bolts 150, clamps 230, and mounting slots, allowing it to be replaced if damaged, thus preventing a damaged connector 240 from affecting the overall test results.

[0030] The implementation principle of this invention is as follows: In use, a pipe carrying the gas to be tested is connected to one of the connectors 240. The gas enters the main body 110 of the testing instrument through the connector 240 and the test tube 130 for testing. After the test is completed, the pipe is separated from the connector 240. When it is necessary to connect the next pipe, the operator moves the L-shaped metal strip 277 out of the slot and separates it from the second magnetic block 279. At this time, the L-shaped metal strip 277 is connected to the first magnetic block 278. Subsequently, the operator presses the movable square strip 275 by manipulating the lever 275. 2. The first spring 273 will contract, and the central connecting block 274 will push the two connecting arms 263. The connecting arms 263 will drive the two sliders 262 to move in opposite directions, causing the two sealing arc plates 265 to move away from each other, and the sealing strip 266 to retract from the annular sealing groove 140. Then, by controlling the lever 275 to rotate the movable square bar 272, the rotating column 271 will be driven to rotate. When the rotating column 271 rotates, it will drive the worm gear 252 through the transmission belt 254. The worm gear 252 will drive the worm wheel 251 to drive the long rod 21. Rotating the long rod 210 causes the conversion disc 220 and connector 240 to rotate. At this time, the one-way ratchet 284 will move out of one of the one-way ratchet grooves 282. When the other connector 240 moves to below the test tube 130, the one-way ratchet 284 will be pushed into the other one-way ratchet groove 282 by the second spring 285 and make a sound. After the sound is made, the operator stops rotating the control handle 275, releases the control handle 275 to allow the first spring 273 to push the movable square bar 272 to reset, so that the two sealing arc plates 26 5. When the test tube 130 and the outer surface of the other connector 240 are brought close together, the sealing strip 266 will also be inserted into the annular sealing groove 140 to improve the sealing performance of the connection. At this time, the L-shaped metal strip 277 is moved into the slot and magnetically connected to the second magnetic block 279, which can lock the state of the movable square strip 272, thereby locking and maintaining the state of the two sealing arc plates 265 and the sealing strip 266, ensuring the subsequent gas sealing and flow, and making it easy to switch the connector 240 to prevent significant impact on subsequent testing.

[0031] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
