Description

Technical Field

[0001] This invention relates to the field of container cleaning devices, and in particular to a cleaning instrument for a Summa can and its method of use. Background Technology

[0002] Sampling is a crucial step in ambient air monitoring. Various sampling methods are available for different sample types. Among them, Summa canister sampling is a commonly used, efficient, and reliable method. With its unique advantages, it is primarily used for gas sample collection and storage, standard gas storage in online monitoring systems, standard gas preparation in laboratories, and gas sample dilution. The inner wall and valve body of the Summa canister are inertized to ensure the stability of components during storage.

[0003] Because Summa canisters are difficult to clean thoroughly, residual substances inside can affect the results of subsequent gas sample analysis, causing measurement errors and failing to meet user needs. The current method involves manually filling the Summa canister with nitrogen, then releasing the nitrogen and refilling it, repeating this process multiple times to achieve cleaning. However, this method is obviously time-consuming, labor-intensive, wasteful of nitrogen, and cannot guarantee standardized operation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a cleaning instrument for Summa cans and its usage method, which can reduce the labor intensity of operators and improve the cleaning efficiency of Summa cans.

[0015] According to the aforementioned cleaning instrument for the Suma can, the inside of the inlet and outlet straight pipe is an air inlet channel, and at least one air hole is opened along the circumference at the bottom end of the inlet and outlet straight pipe.

[0016] The gas connection component includes a cylindrical connector body, the upper end of which is a straight pipe connection end facing the inlet and outlet straight pipes; the lower end of the connector body is a Suma canister connection end, and the Suma canister connection end 803 has an axially arranged lower end channel for the connector, and the end of the Suma canister connection end is detachably connected to the gas sampling port of the Suma canister.

[0017] The straight pipe connection end has a cylindrical groove inside. The inner side of the cylindrical groove has a first annular groove and a second annular groove that are axially spaced along the circumferential direction. A first sealing gasket and a second sealing gasket are respectively installed in the first annular groove and the second annular groove. The cylindrical groove space between the first sealing gasket and the second sealing gasket forms a buffer zone. The inlet and outlet straight pipes are movably fitted in the first sealing gasket and the second sealing gasket.

[0018] A limiting cylinder is installed inside the cylindrical groove, which coincides with the central axis of the cylindrical groove. The limiting cylinder is a cylindrical structure with an open top and a closed bottom. The outer diameter of the limiting cylinder is smaller than the diameter of the cylindrical groove. An internal airflow channel is formed between the limiting cylinder and the inner wall of the connector body, which is connected to the lower end channel of the connector.

[0019] The inner cavity of the limiting cylinder is equipped with a movable column, and the central axis of the movable column coincides with the central axis of the limiting cylinder;

[0087] To make the technical problem to be solved, the technical solution and advantages of the present invention clearer, the following description will be provided in conjunction with the accompanying drawings. Figures 1 to 33 The technical solutions of the present invention are clearly and completely described herein with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0088] The cleaning instrument for the Suma can includes a frame 100, a transmission device 200, several connecting plates 300, a mounting base 400, a lifting device 600, an air circuit device 700, and air circuit connection components 800, such as... Figures 1 to 5 As shown. The transmission device 200 is fixedly mounted on the frame 100. Several connecting trays 300 are fixedly mounted on the transmission device 200 at equal intervals. The mounting base 400 is fixedly mounted on the upper surface of the connecting trays 300 for mounting the Summa can 500; the inner side of the mounting base 400 is an annular inclined surface, which serves to guide and position the Summa can 500.

[0089] The transmission device 200 can be a motor-gear-rack structure, where the motor is connected to the gear, the motor drives the gear to rotate, and the gear drives the rack to move back and forth. The connecting plate 300 is fixedly mounted on the rack. Alternatively, the transmission device 200 can be a motor-driven chain, with the connecting plate 300 fixed to the chain. The transmission device 200 can also be a motor-driven drive belt, with the drive belt fixed to the connecting plate 300, enabling movement of the connecting plate 300, as detailed below:

[0090] like Figures 6 to 9 As shown, the transmission device 200 includes a drive motor 201, a reducer 202, an annular guide rail 203, a rotating wheel 204, a rotating shaft 205, a transmission belt 206, and a slide 208. The drive motor 201 is fixedly installed inside the frame 100. Rotating shafts 205 are rotatably installed at the four corners of the upper end of the frame 100. The output end of the drive motor 201 is fixedly connected to the bottom of one of the rotating shafts 205. Bearing sleeves 207 are provided on the other three rotating shafts 205, and the bearing sleeves 207 are fixedly installed inside the frame 100. Rotating wheels 204 are fixedly connected to each of the four rotating shafts 205, and the four rotating wheels 204 are connected by a transmission belt 206. A reducer 202 is installed on the drive motor 201. Slide seats 208 are fixedly connected at equal intervals on the outer side of the conveyor belt. The slide seats 208 are slidably connected to the annular guide rail 203, and the annular guide rail 203 is fixedly installed on the top of the frame 100. A connecting plate 300 is fixedly provided on the upper surface of the slide seat 208.

[0091] After the operator connects the lower end of the Summa canister connection 803 of the gas connection component 800 to the gas intake port 501 of the Summa canister 500, multiple Summa canisters 500 with gas connection components 800 are placed at intervals on the mounting base 400. The transmission device 200 drives the connecting plate 300 to move, thereby moving the Summa canisters 500 at equal intervals. After one Summa canister 500 is cleaned, the gas connection component 800 above the next Summa canister 500 is moved below the inlet / outlet straight pipe 704 to clean the next Summa canister 500, reducing the workload of the operator.

[0092] The lifting device 600 is fixedly mounted at the rear end of the frame 100, and includes a lifting component bracket 601 fixedly mounted on the frame 100, a lifting drive component 602 fixedly mounted on the lifting component bracket 601, and a connecting block 603 fixedly mounted at the lower end of the lifting drive component 602. One structure of the lifting drive component 602 in the lifting device 600 is an electric cylinder, and the end of the telescopic rod of the electric cylinder is fixedly connected to the connecting block 603, such as... Figure 5 As shown. Alternatively, the lifting drive component 602 can be a cylinder, a hydraulic cylinder, or a motor-driven rack and pinion structure; any structure capable of linearly moving the connecting block 603 can be used as the lifting drive component 602. Any component capable of enabling the connecting block 603 to move vertically upwards or downwards is acceptable.

[0093] like Figure 5 , Figure 14 and Figure 15 As shown, the pneumatic circuit device 700 includes a three-way solenoid valve 701, an inflation pipe 702, an exhaust pipe 703, and inlet / outlet straight pipes 704. The three-way solenoid valve is a commonly used electromagnetic control valve, consisting of an electromagnet and a valve body. It has two operating positions (ON and OFF) and three interfaces: a first interface 7011, a second interface 7012, and a third interface 7013. The three-way solenoid valve 701 is mounted on the connecting block 603; the first interface 7011 of the three-way solenoid valve 701 is connected to the upper end of the inlet / outlet straight pipe 704; the second interface 7012 of the three-way solenoid valve 701 is connected to one end of the inflation pipe 702, and the other end of the inflation pipe 702 is connected to a cleaning air tank; the third interface 7013 of the three-way solenoid valve 701 is connected to one end of the exhaust pipe 703, and the other end of the exhaust pipe 703 is connected to a vacuum pump.

[0094] The upper end of the gas connection component 800 is movably connected to the lower end of the inlet / outlet straight pipe 704, and the lower end of the gas connection component 800 is detachably connected to the gas intake port 501 of the Summa tank 500.

[0095] The drive motor 201 drives the rotating shaft 205 to rotate, the rotating shaft 205 drives the rotating wheel 204 to rotate, the rotating wheel 204 drives the transmission belt 206 to rotate, the transmission belt 206 drives the slide 208 to move, and then drives the connecting plate 300 to slide along the annular guide rail 203, thereby driving the Suma can 500 to move at equal intervals.

[0096] The lifting device 600 drives the lifting of the three-way solenoid valve 701, and the lifting of the three-way solenoid valve 701 drives the lifting of the inlet and outlet straight pipes 704, thereby realizing the connection and disconnection of the inlet and outlet straight pipes 704 and the air connection component 800.

[0097] By controlling the opening and closing of the three-way solenoid valve 701, the flow of gas during the cleaning process is controlled. After the inlet / outlet gas pipe 704 and the gas connection component 800 are connected, the second port 7012 of the three-way solenoid valve 701 closes, and the third port 7013 of the three-way solenoid valve 701 opens. After the vacuum pump is turned on, the gas inside the Suma tank 500 is extracted. After a period of time, the third port 7013 of the three-way solenoid valve 701 closes, and the second port 7012 of the three-way solenoid valve 701 opens, flushing the cleaning gas inside the cleaning gas tank into the Suma tank 500. Nitrogen is commonly used. This cycle continues until the inside of the Suma tank is thoroughly cleaned.

[0098] The cleaning instrument for Suma cans of this invention uses a transmission device to move a connecting tray, which in turn moves the Suma cans. A lifting device moves the inlet and outlet air pipes downwards. After the inlet and outlet air pipes connect to the air path connection component, a vacuum is circulated inside the Suma can, followed by the filling with cleaning gas to clean the interior. After cleaning, the lifting device moves the inlet and outlet air pipes upwards, separating them from the air path connection component. The transmission device then moves the next Suma can with the air path connection component below the inlet and outlet air pipe, thus completing the internal cleaning of multiple Suma cans. The cleaning instrument for Suma cans features a clever structural design, enabling the cleaning of multiple Suma cans at once, reducing the workload of operators, and providing high cleaning stability.

[0099] like Figures 10 to 12 As shown, the slide block 208 includes a slot block 2081. A bearing mounting plate 2082 is fixedly connected to one side of the slot block 2081, and the upper part of the bearing mounting plate 2082 is fixedly connected to the connecting support plate 300. At least two bearing pulleys 2083 are provided at the bottom of the bearing mounting plate 2082. The bearing pulleys 2083 are slidably connected to the annular guide rail 203. A locking pin 2084 is fixedly connected to the other side of the slot block 2081 corresponding to the bearing mounting plate 2082, and the locking pin 2084 is fixedly connected to the transmission belt 206. In this embodiment, four bearing pulleys 2083 are provided at the bottom of the bearing mounting plate 2082. Figure 13 As shown, the connecting plate 300 is fixedly mounted on the upper part of the bearing mounting plate 2082.

[0100] Specifically, a motor mount 209 is fixedly installed inside the frame 100, and the drive motor 201 is installed in the motor mount 209, such as... Figure 8 As shown; a guide rail base plate 2010 is provided on the top of the frame 100, and an annular guide rail is fixedly mounted on the guide rail base plate 2010, as shown. Figure 7 As shown.

[0101] The lifting drive component 602 drives the connecting block 603 to move up and down, which in turn moves the three-way solenoid valve 701 up and down, thereby moving the inlet and outlet air straight pipe 704 up and down. When the inlet and outlet air straight pipe 704 moves downwards and connects to the air passage connection component 800, the lifting drive component 602 stops operating, and the cleaning process inside the Summa tank 500 begins. After cleaning, the lifting drive component 602 drives the connecting block 603 to move upwards, disconnecting the inlet and outlet air straight pipe 704 from the air passage connection component 800.

[0102] The inlet and outlet straight pipe 704 is a rigid pipe, which can be connected to the air connection component 800; the inflation pipe 702 and the suction pipe 703 are flexible pipes, which move with the connecting block 603.

[0103] An adsorption filter (not shown in the figure) is installed on the extraction pipe 703, and the adsorption filter is connected to the inside of the extraction pipe 703. Organic pollutants and water vapor extracted from the Suma tank 500 are absorbed by the adsorption filter and transformed into clean gas, which is then discharged by the vacuum pump. This effectively cleans the Suma tank 500 while preventing organic pollutants in the organic waste from volatilizing into the air, ensuring experimental safety and preventing operators from inhaling polluted gases discharged from the Suma tank 500 that could affect their health.

[0104] It also includes a controller 900 disposed inside the rack 100 and a touch screen bracket 1000 and a touch screen 1100 fixed to one side of the rack 100, such as Figure 1 and Figure 4 As shown, the controller 900 is electrically connected to the touch screen 1100, and the lifting drive component 602, transmission device 200, three-way solenoid valve 701, and touch screen 1100 are all electrically connected to the controller 900. The touch screen 1100 can be used to input and set cleaning control conditions such as the pressure of the cleaning gas filling the cleaning gas tank, the speed of the cleaning gas, the vacuum pressure, the vacuuming speed, and the number of cleaning gas filling-vacuuming cycles.

[0105] It also includes: a positioning block 1200 fixed to the outer end face of the connecting plate 300 and a positioning detection sensor 1300 fixed to the lifting component bracket 601, such as Figure 2 As shown. The positioning detection sensor 1300 is electrically connected to the controller 900. The positioning detection sensor 1300 detects a positioning block 1200 on the outside of the connecting tray 300. At this time, the air passage connection component 800 on the top of the Summa can 500 on the connecting tray is vertically aligned with the inlet and outlet air straight pipe 704, ensuring that the lifting device 600 drives the inlet and outlet air straight pipe 704 to accurately connect with the air passage connection component 800.

[0106] It also includes a pressure sensor 1500 installed on the inlet / outlet straight pipe 704, such as Figure 5As shown. Pressure sensor 1500 is electrically connected to controller 900. Pressure sensor 1500 is used to detect the pressure of the cleaning gas filling the SUMMA can 500 and the vacuum pressure inside the SUMMA can 500 during vacuuming.

[0107] The transmission device 200 drives the connecting tray 300 to move, thereby moving the Suma cans 500 at equal intervals. When the positioning detection sensor 1300 detects the positioning block 1200, the transmission device 200 stops operating, and the lower end of the air inlet aligns with the upper end of the air outlet aligns, ensuring that the air inlet accurately connects with the air outlet when the lifting device 600 lowers the air inlet / outlet straight pipe 704, thus achieving automated control of the Suma can cleaning instrument. After one Suma can 500 is cleaned, the transmission device 200 is started. When the positioning detection sensor 1300 detects the positioning block 1200 on the outer end face of the next connecting tray 300, the transmission device 200 stops operating, and the next Suma can 500 is cleaned.

[0108] It also includes a scanner 1400 that is electrically connected to the controller 900 and is fixedly mounted on the lifting component bracket 601, such as Figure 2 As shown. When the positioning detection sensor 1300 detects the positioning block 1200, the scanner 1400 identifies the ID code on the Suma can 500 at the cleaning position and transmits the Suma can 500 information to the controller 900. The information is then displayed and stored on the touch screen 1100, realizing intelligent recording of the Suma can cleaning instrument and reducing the workload of operators.

[0109] The cleaning equipment for Suma canisters can be used automatically and intelligently, enabling precise control of the cleaning process and avoiding waste of cleaning gas.

[0110] This invention provides an inlet / outlet straight pipe 704 and an air passage connection component 800, as detailed below:

[0111] The interior of the inlet / outlet straight pipe 704 is a straight pipe channel 7041, and at least one air hole 7042 is opened along the circumference at the bottom end of the inlet / outlet straight pipe 704, such as... Figure 19 and Figure 20 As shown.

[0112] like Figures 21 to 26 As shown, the gas connection component 800 includes a cylindrical connector body 801, the upper end of which is a straight pipe connection end 802; the lower end of the connector body 801 is a Suma canister connection end 803, and a lower end channel 804 for the connector is provided axially inside the Suma canister connection end 803. The end of the Suma canister connection end 803 is detachably connected to the gas intake port 501 of the Suma canister 500.

[0113] The straight pipe connection end 802 has a cylindrical groove 805 inside. A first annular groove 806 and a second annular groove 807, axially spaced along the circumferential direction, are formed inside the cylindrical groove 805. A first sealing gasket 808 and a second sealing gasket 809 are respectively disposed in the first annular groove 806 and the second annular groove 807. Since the first sealing gasket 808 and the second sealing gasket 809 are respectively fitted onto the first annular groove 806 and the second annular groove 807, the first sealing gasket 808 and the second sealing gasket 809 are prevented from falling off, ultimately resulting in a better sealing effect. The space in the cylindrical groove 805 between the first sealing gasket 808 and the second sealing gasket 809 forms a buffer zone 810. When the inlet / outlet straight pipe 704 is connected to the gas connection component 800, the inlet / outlet straight pipe 704 is movably fitted into the first sealing gasket 808 and the second sealing gasket 809, preventing external gas from entering the internal space during the connection process and causing gas contamination.

[0114] A limiting cylinder 811, which coincides with the central axis of the cylindrical groove 805, is provided inside the cylindrical groove 805. The structure of the limiting cylinder 811 is as follows: Figures 27 to 29 As shown, the limiting cylinder 811 is a cylindrical structure with an open upper end and a closed lower end. The outer diameter of the limiting cylinder 811 is smaller than the diameter of the cylindrical groove 805. An internal airflow channel 812 is formed between the limiting cylinder 811 and the inner wall of the connector body 801, which communicates with the lower end channel 804 of the connector. A movable column 815 is provided in the inner cavity of the limiting cylinder 811. The central axis of the movable column 815 coincides with the central axis of the limiting cylinder 811. The movable column 815 can move up and down along the central axis in the inner cavity of the limiting cylinder 811.

[0115] The top of the movable column 815 is connected to a frustum base 817, and the central axis of the frustum base 817 and the movable column 815 coincides. Figure 30 As shown. The connection between the frustum base 817 and the movable column 815 can be a slot connection, a threaded connection, an adhesive connection, or an integral molding. The diameter of the upper bottom surface of the frustum base 817 is smaller than the diameter of the lower bottom surface, and the diameter of the lower bottom surface of the frustum base 817 is larger than the diameter of the movable column 815. The lower bottom surface of the frustum base 817 is connected to the movable column 815. The diameter of the lower bottom surface of the frustum base 817 is larger than the inner diameter of the limiting cylinder 811, and the frustum base 817 moves between the limiting cylinder 811 and the second sealing gasket 809. The diameter of the upper bottom surface of the frustum base 817 is larger than the inner diameter of the inlet / outlet straight pipe 704, and the bottom end of the inlet / outlet straight pipe 704 is movably connected to the upper bottom surface of the frustum base 817. During the process of filling the Suma can 500 with gas, when the bottom end of the inlet / outlet straight pipe 704 contacts the top surface of the frustum base 817, the gas in the straight pipe channel 7041 can flow out from the air hole 7042 of the inlet / outlet straight pipe 704 to the internal airflow channel 812.

[0116] like Figure 24As shown, a spring 816 is provided in the inner cavity of the limiting cylinder 811. One end of the spring 816 is fixed in the middle of the bottom surface of the inner cavity of the limiting cylinder 811. The fixing method can be adhesive or snap-fit. The other end of the spring 816 abuts against the bottom surface of the movable column 815.

[0117] While providing a sealing function, the second sealing gasket 809 and the limiting cylinder 811 also limit the movement of the frustum base 817 at both ends.

[0118] A positioning support 818 is fixedly provided on the lower end face of the limiting cylinder 811, so that the central axis of the limiting cylinder 811 coincides with the central axis of the cylindrical groove 805, while ensuring that the internal airflow channel 812 is connected to the lower end channel 804 of the connector. The fixing method is adhesive bonding, snap-fitting, or threaded connection.

[0119] The combined structure of the first annular groove 806 and the second annular groove 807, along with the corresponding first sealing gasket 808 and the second sealing gasket 809, ensures the sealing effect of the internal space during the connection, ventilation, and separation processes of the inlet and outlet straight pipe 704 and the gas connection component 800, preventing external gas from entering the internal space and affecting the purity of the internal circulating gas.

[0120] The spring 816 inside the limiting cylinder 811 enables the automatic reset of the frustum base 817, making it more convenient to use; at the same time, it prevents external gas from entering the internal space of the gas connection component 800 during the process of the inlet / outlet straight pipe 704 being removed from the gas connection component 800, thus affecting the purity of the gas introduced next time.

[0121] In a preferred embodiment of the present invention: a third annular groove 813 is provided in the inner cavity of the limiting cylinder 811 near the opening along the circumferential direction, a third sealing gasket 814 is provided in the third annular groove 813, and a movable column 815 is sleeved inside the third sealing gasket 814, which can slide within the third sealing gasket 814.

[0122] By setting a third sealing gasket 814 at the opening of the limiting cylinder 811, the closed space that is prone to gas accumulation inside the limiting cylinder 811 is avoided due to the up-and-down movement of the movable column 815 within the limiting cylinder 811, thus preventing gas contamination.

[0123] Another preferred embodiment of the present invention: the structure of the positioning support 818 is as follows Figure 31 and Figure 32As shown, the positioning support 818 includes a positioning rod 8181 and at least one support arm 8182 located on the top surface of the positioning rod 8181. In this embodiment, two symmetrical support arms 8182 are provided. The positioning rod 8181 is engaged in the lower end channel 804 of the connector, serving to position and limit the central axis of the cylinder 811 to coincide with the central axis of the cylindrical groove 805. The upper end face of the support arm 8182 contacts the lower end face of the limiting cylinder 811, and the lower end face of the support arm 8182 contacts the bottom end face of the cylindrical groove 805, serving to support and limit the cylinder 811. The positioning rod 8181 is not in complete contact with the side wall of the lower end channel 804 of the connector; the positioning rod 8181 is partially attached to the side wall of the lower end channel 804 of the connector, ensuring that the internal airflow channel 812 communicates with the lower end channel 804 of the connector.

[0124] Furthermore, to accommodate a large flow of gas passing through the space between the internal airflow channel 812 and the lower end channel 804 of the connector, the positioning support 818 has a shell structure, forming a positioning support cavity 8183, such as... Figure 33 As shown. When cleaning gas is filled into the Suma can 500, part of the airflow enters the lower end channel 804 of the connector from the internal airflow channel 812, and the other part of the airflow flows from the outside of the positioning support 818 to the lower end channel 804 of the connector.

[0125] The first sealing gasket 808, the second sealing gasket 809, and the third sealing gasket 814 are made of silicone rubber. They deform under pressure and return to their original shape after the external force is removed, thus ensuring the sealing effect.

[0126] The gas connection component and inlet / outlet straight pipes provided in this embodiment of the invention simplify the connection method. Compared with the traditional connection method, this gas connection component and inlet / outlet straight pipes can not only reduce connection time and labor costs, but also ensure the sealing of the connection process, intermediate process and disconnection process.

[0127] Working principle of inlet / outlet straight pipe 704 and air connection component 800:

[0128] During the insertion of the inlet / outlet straight pipe 704 into the air passage connection component 800, the central axes of the air passage connection component 800 and the inlet / outlet straight pipe 704 coincide. The first sealing gasket 808 and the second sealing gasket 809 are tightly attached to the outer sides of the inlet / outlet straight pipe 704, respectively. The air hole 7042 of the inlet / outlet straight pipe 704 passes through the buffer zone 810 between the first sealing gasket 808 and the second sealing gasket 809. After the bottom end of the inlet / outlet straight pipe 704 contacts the upper bottom surface of the frustum base 817, the inlet / outlet straight pipe 704 further pushes the frustum base 817 towards the limiting cylinder 811, and the spring 816 is compressed by the movable column 815. After passing through the buffer zone 810, the bottom air hole 7042 of the inlet / outlet straight pipe 704 further moves downward towards the cylindrical groove 805. When the lower surface of the frustum base 817 contacts the open end of the limiting cylinder 811, the frustum base 817 stops moving. At this time, the vent 7042 moves into the internal space below the second sealing gasket 809, as... Figures 16 to 18 As shown. When cleaning gas is introduced into the Suma canister 500, the cleaning gas flows from the straight pipe channel 7041 to the vent 7042 and then into the internal space. It then flows through the internal airflow channel 812 to the lower end channel 804 of the connector, and finally exits through the gas connection component 800 into the Suma canister 500. During the vacuuming process, the airflow direction is opposite to the direction of the introduced cleaning gas. The connection state of the inlet and outlet straight pipes 704 and the gas connection component 800, as well as the internal structure of the gas connection component 800, remain unchanged.

[0129] When the movable column 815 loses pressure from the inlet / outlet straight pipe 704, the bottom end of the inlet / outlet straight pipe 704 moves toward the top end of the connector body 801, the spring 816 rebounds, and the inlet / outlet straight pipe 704 moves synchronously with the frustum base 817. After the side of the frustum base 817 abuts against the second sealing gasket 809, the inlet / outlet straight pipe 704 separates from the frustum base 817, and then the inlet / outlet straight pipe 704 moves out of the gas connection component 800. This enables the frustum base 817 to automatically reset, making it more convenient to use. At the same time, it avoids the entry of external gas into the internal space of the gas connection component 800 during the process of the inlet / outlet straight pipe 704 moving out of the gas connection component 800, which would affect the purity of the gas when the inlet / outlet straight pipe 704 and the gas connection component 800 are connected next time.

[0130] This invention also provides a method for using the cleaning instrument for the above-mentioned Suma can, including the following steps:

[0131] S1. Connect the lower port of the gas connection part 803 of the gas connection part 800 to the gas intake port 501 of the gas connection part 500.

[0132] S2. The operator places multiple 800 Suma canisters 500 with gas connection components at intervals on the mounting base 400.

[0133] S3, the transmission device 200 rotates, thereby driving the Suma can 500 to move at equal intervals;

[0134] S4. The inlet and outlet straight pipe 704 is aligned with the air connection component 800 above a Summa can 500, and the transmission device 200 is stopped; the lifting device 600 operates, causing the connecting block 603 to move downward, which in turn drives the inlet and outlet straight pipe 704 to move downward, and the inlet and outlet straight pipe 704 connects with the air connection component 800.

[0135] S5. The second port 7012 of the three-way solenoid valve 701 is closed, and the third port 7013 of the three-way solenoid valve 701 is opened. After the vacuum pump is turned on, the gas inside the Suma canister 500 is extracted. After the vacuuming set time is reached, the third port 7013 of the three-way solenoid valve 701 is closed, and the second port 7012 of the three-way solenoid valve 701 is opened, and the gas inside the cleaning gas tank is injected into the Suma canister 500.

[0136] S6. Repeat step S5 to cycle through the vacuuming and cleaning gas filling process.

[0137] S7. After the internal cleaning of the S7 tank 500 is completed, the lifting device 600 controls the connecting block 603 to move upward, which drives the inlet and outlet straight pipe 704 to move upward, and the inlet and outlet straight pipe 704 and the air connection component 800 are separated.

[0138] S8. Repeat steps S3 to S7 to complete the cleaning of multiple Summa 500 tanks.
