Description

Technical Field

[0001] The invention belongs to the technical field of fire extinguisher processing, and in particular relates to a cleaning device for processing a fire extinguisher bottle and a use method thereof. Background Art

[0002] The fire extinguisher bottle is the main part of the fire extinguisher. During the processing of the fire extinguisher bottle, the fire extinguisher bottle needs to be cleaned to remove dirt and impurities inside the bottle to ensure the subsequent processing of the fire extinguisher.

[0003] The prior art invention patent with publication number CN116274220B discloses a cleaning device for processing dry powder fire extinguisher cylinders, which includes a clamping assembly for fixing the fire extinguisher cylinder. The clamping assembly can drive the fire extinguisher cylinder to move. The fire extinguisher cylinder is inserted into the cleaning assembly, which is installed at the lower end of the clamping assembly. The upper end of the cleaning assembly is provided with a multi-angle adjustable spray head and a multi-track adjustable drying head. The middle section of the cleaning assembly is provided with a stirring fan for stirring the cleaning agent. The bottom end of the cleaning assembly is provided with a water pump for recovering and filtering the cleaning agent. In this technology, the extension and retraction of the stirring blades are achieved through the transmission coordination of the telescopic motor, gear 2, gear 1, rotating disk, limit slot, sliding block and other structures. Therefore, a more complex structure needs to be set in each set of cleaning components. Once the transmission coordination between these structures is damaged or fails, it is more troublesome to repair; in addition, since the diameter of the bottle mouth of the fire extinguisher bottle is different from the diameter of other parts, the extension distance of the stirring blades at the bottle mouth of the fire extinguisher bottle and other parts is different, and the operator needs to control and adjust it separately, which is more troublesome. Therefore, this technology needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned technical problems and provide a cleaning device for processing fire extinguisher bottles and a method of use thereof. The centrifugal force generated during the rotation of the carrier can switch the soft brush between the expanded state and the stored state, and can automatically adapt to the extension distance of the soft brush, thereby simplifying the overall structure of the cleaning device and improving the cleaning efficiency of the fire extinguisher bottle.

[0005] In view of this, the present invention provides a cleaning device for processing fire extinguisher bottles, comprising: The device body has a plurality of cleaning tanks, each of which is provided with a cleaning mechanism; The cleaning mechanism includes: a base, the base being provided with a positioning groove for positioning the open end of the fire extinguisher bottle; A clamping unit, which is used to clamp the positioned fire extinguisher bottle; The main shaft rotates in the positioning groove, and multiple groups of movable brush units are arranged on the main shaft along the axial direction; A power source, which is used to drive the main shaft to rotate; Among them, when the main shaft rotates, the movable brush unit can switch to the expanded state under the action of centrifugal force, and when the main shaft is stationary, the movable brush unit switches to the stored state. The main shaft and the movable brush unit in the stored state can extend axially into the interior of the fire extinguisher bottle, and the movable brush unit can contact the inner wall of the fire extinguisher bottle in the expanded state.

[0006] In this technical solution, the open end of the fire extinguisher bottle is passed through the main shaft and multiple movable brush units in the storage state and then placed into the positioning groove. At this time, the fire extinguisher bottle is clamped by the clamping unit so that the fire extinguisher bottle is coaxial with the main shaft. Then the power source is started to drive the main shaft to rotate, so that the movable brush unit switches to the expanded state under the action of centrifugal force. In the expanded state, the movable brush unit scrubs the inner wall of the fire extinguisher bottle. After the scrubbing is completed, the power source is turned off, and the main shaft stops rotating. The movable brush unit switches to the storage state, and the clamping unit releases the fire extinguisher bottle. At this time, the fire extinguisher bottle can be removed to complete the cleaning.

[0007] In the above technical solution, further, the cleaning mechanism also includes a spraying unit, which is arranged on the main shaft and is used to spray cleaning liquid and clean water onto the inner wall of the fire extinguisher bottle.

[0008] In the above technical solution, further, the spraying unit includes multiple nozzles and a delivery pipe, the multiple nozzles are arranged on the main shaft, the delivery pipe is arranged in the main shaft, one end of the delivery pipe is connected to the nozzle, and the other end of the delivery pipe can be connected to an external liquid supply device.

[0009] In the above technical solution, further, a drainage groove is provided on the bottom surface of the positioning groove, and the drainage groove is connected to the cleaning groove.

[0010] In the above technical solution, further, the clamping unit includes: A gas flow channel is provided in the base, one end of which can be connected to an external gas extraction device; A plurality of adsorption holes are arranged in the positioning groove at intervals, and the adsorption holes are communicated with the other end of the gas flow channel.

[0011] In the above technical solution, further, the movable brush unit includes: A mounting plate, the mounting plate being coaxially connected to the main shaft; A swing arm, wherein a first end of the swing arm is rotatably connected to the mounting plate, and a soft brush is provided at a second end of the swing arm. When the mounting plate rotates, the second end of the swing arm can swing toward the outside of the mounting plate under the action of centrifugal force to put the movable brush unit in an expanded state; The elastic telescopic member is respectively connected to the swing arm and the mounting plate. When the swing arm is not subjected to the centrifugal force, the elastic telescopic member can hide the second end of the swing arm in the mounting plate to put the movable brush unit in a storage state.

[0012] In the above technical solution, further, the movable brush unit also includes: A locking groove is provided at the second end of the swing arm; A swing locking piece, one end of the swing locking piece is rotatably connected to the mounting plate, and the other end of the swing locking piece has a hook, which can be clamped into and out of the locking groove during the swinging process of the swing locking piece. When the hook is clamped into the locking groove, the swing arm can be locked in the mounting plate, and the swing arm can be unlocked after the hook is withdrawn from the locking groove.

[0013] In the above technical solution, further, a fixed column is provided on the mounting plate, one end of the swing locking piece is sleeved on the fixed column, and a torsion elastic piece is sleeved on the fixed column. When the swing locking piece swings relative to the fixed column, the torsion elastic piece will be squeezed; an electromagnetic unit is provided on the mounting plate and located on the side of the swing locking piece away from the locking groove. The electromagnetic unit can drive the swing locking piece to exit the locking groove when energized.

[0014] The present invention also discloses a method for using a cleaning device for processing fire extinguisher bottles, which is applicable to the aforementioned cleaning device and includes the following steps: Positioning the fire extinguisher bottle: Place the open end of the fire extinguisher bottle downward so that the main shaft and the movable brush unit enter the fire extinguisher bottle, and place the open end of the fire extinguisher bottle into the positioning groove so that the outer wall of the fire extinguisher bottle blocks the adsorption hole to complete the positioning of the fire extinguisher bottle; Fire extinguisher bottle clamping: connect the gas flow channel to the air extraction device, start the air extraction device to generate negative pressure in the gas flow channel and the adsorption hole, and suck the positioned fire extinguisher bottle to complete the fire extinguisher bottle clamping; Cleaning fluid spraying: Start the spraying unit to spray the cleaning fluid from top to bottom inside the fire extinguisher bottle; Washing: Start the power source to drive the main shaft to rotate, and the main shaft drives the mounting plate to rotate. The second end of the swing arm generates centrifugal force on the mounting plate and overcomes the elastic force of the elastic telescopic member to swing toward the outside of the mounting plate. Finally, the soft brush at the second end of the swing arm contacts the inner wall of the fire extinguisher bottle and moves along the circumference of the fire extinguisher bottle, thereby washing the inner wall of the fire extinguisher bottle; Clean water spraying: Start the spraying unit to spray clean water from top to bottom inside the fire extinguisher bottle; Fire extinguisher bottle release: turn off the power source to switch the movable brush unit to the storage state, connect the gas flow channel to the atmosphere, and remove the fire extinguisher bottle from the base.

[0015] The beneficial effects of the present invention are: 1. By providing a main shaft that can be extended into the interior of the fire extinguisher bottle and multiple groups of movable brush units, these movable brush units can automatically expand under the action of centrifugal force when the main shaft rotates, and stop and reach the corresponding expanded state when they come into contact with the inner wall of the fire extinguisher bottle; this cleverly utilizes the effect of centrifugal force without adding a complicated mechanical structure to achieve the switching of the movable brush units between the expanded state and the stored state, simplifying the structure of the movable brush units, and each movable brush unit can automatically adapt to positions of different diameters, thereby achieving efficient cleaning of the fire extinguisher bottle.

[0016] 2. By arranging a spraying unit on the main shaft, the spraying unit can spray cleaning fluid and clean water into the interior of the fire extinguisher bottle, which can cooperate with the cleaning of the movable brush unit to improve the cleaning effect of the fire extinguisher bottle.

[0017] 3. By designing the clamping unit into a structure of gas flow channel and multiple adsorption holes, when the open end of the fire extinguisher bottle blocks these adsorption holes, the gas flow channel is connected to the exhaust device to generate negative pressure in the gas flow channel and the adsorption holes, thereby sucking the fire extinguisher bottle and ensuring the stability of the fire extinguisher bottle during the cleaning process. At the same time, the gas adsorption method is more environmentally friendly, and there is no need to add complicated mechanical structures to fix the fire extinguisher bottle, which simplifies the structure of the cleaning device, reduces the overall volume of the cleaning device, and reduces the environmental requirements for the use of the cleaning device.

[0018] 4. By designing the movable brush unit into a combination of a mounting plate, a swing arm, a soft brush, and an elastic telescopic part, the mounting plate will rotate with the main shaft when the main shaft rotates. When the centrifugal force exerted on the swing arm on the mounting plate is greater than the elastic force of the elastic telescopic part, the swing arm will swing and expand to the outside of the mounting plate, so that the soft brush can contact the inner wall of the fire extinguisher bottle to clean the fire extinguisher bottle. When the centrifugal force exerted on the swing arm on the mounting plate is less than the elastic force of the elastic telescopic part, the swing arm will be pulled back into the mounting plate by the elastic telescopic part until it is hidden. In this way, the movable brush unit can automatically switch between the deployed state and the stored state, with an ingenious structure and easy maintenance.

[0019] 5. By providing a locking groove on the swing arm and providing a movable swing locking piece on the mounting plate to cooperate with the locking groove, the swing arm can be locked and unlocked. In this way, when the movable brush unit is transported or one or more movable brush units on the main shaft are inspected, the movable brush unit that does not need to be unfolded will not interfere with the corresponding transportation or inspection. Moreover, through the cooperation of the electromagnetic unit and the torsional elastic piece, the swing arm can be automatically locked and unlocked by simply controlling the power on and off of the electromagnetic unit, which simplifies the operation of the operator and further improves the overall structural stability of the movable brush unit.

[0034] Fire extinguisher bottle The fire extinguisher bottle 100 of the present invention is structured as follows: Figure 3 As shown, the body of the fire extinguisher bottle 100 is a hollow cylinder, the opening diameter of the open end of the fire extinguisher bottle 100 is smaller than the diameter of the body of the fire extinguisher bottle 100, and there is an arc transition between the open end and the body of the fire extinguisher bottle 100.

[0035] Example 1 The embodiment of the present application provides a cleaning device for processing fire extinguisher bottles, comprising a device body 1, See also Figure 1 and Figure 2 , the device body 1 has several cleaning tanks 101, and two cleaning tanks 101 are taken as an example in the figure. Each cleaning tank 101 is provided with a cleaning mechanism 2, and a control box is provided on one side of the device body 1 for controlling the circuit part of the cleaning device; Figure 1 and Figure 2 Of the two cleaning mechanisms 2 shown in FIG, one cleaning mechanism 2 has a fire extinguisher bottle 100 positioned thereon, while the other cleaning mechanism 2 does not have a fire extinguisher bottle 100; See also Figure 4 and Figure 5 , the cleaning mechanism 2 includes: a base 3, a clamping unit, a main shaft 5, and a power source 7; The base 3 is provided with a positioning groove 301 for positioning the open end of the fire extinguisher bottle 100. The bottom surface and the side wall of the positioning groove 301 have an arc transition. The size of the positioning groove 301 is adapted to the open end of the fire extinguisher bottle 100. The clamping unit is used to clamp the positioned fire extinguisher bottle 100. The clamping unit can clamp the bottle body of the fire extinguisher bottle 100 or the open end of the fire extinguisher bottle 100. The structure of the clamping unit can adopt the mechanical clamping method in the prior art, or other clamping methods in the prior art, such as pneumatic clamping, hydraulic clamping, combined clamping, etc. Figure 1 and Figure 2 The structure of the clamping unit is hidden in the figure; The main shaft 5 is rotatably arranged in the positioning groove 301, and the diameter of the main shaft 5 is smaller than the diameter of the open end of the fire extinguisher bottle 100; See also Figure 5 The power source 7 is provided in the base 3 for driving the main shaft 5 to rotate. In this embodiment, the power source 7 is a servo motor. The output shaft of the servo motor is connected to the bottom end of the main shaft 5. When the servo motor is started, the main shaft 5 can be driven to rotate. The main shaft 5 is provided with a plurality of movable brush units 6 along the axial direction. For the structure of the movable brush units 6, please refer to Figure 6 When the main shaft 5 rotates, the movable brush unit 6 can be switched to the expanded state under the action of centrifugal force. Figure 6 The movable brush unit 6 is in an expanded state. In the expanded state, the overall diameter of the movable brush unit 6 can be larger than the maximum inner diameter of the fire extinguisher bottle 100. When the main shaft 5 is stationary, the movable brush unit 6 switches to the retracted state. In the retracted state, the overall diameter of the movable brush unit 6 is smaller than the opening diameter of the open end of the fire extinguisher bottle 100. The main shaft 5 and the movable brush unit 6 in the retracted state can axially extend into the interior of the fire extinguisher bottle 100. The movable brush unit 6 can contact the inner wall of the fire extinguisher bottle 100 in the expanded state. In this embodiment, the operator directs the open end of the fire extinguisher bottle 100 toward the positioning groove 301, and axially sleeves the fire extinguisher bottle 100 from the open end onto the outside of the main shaft 5 and multiple sets of movable brush units 6, and then contacts and positions it with the positioning groove 301. The clamping unit then clamps the positioned fire extinguisher bottle 100, and then starts the power source 7 to drive the main shaft 5 to rotate. During the rotation, the main shaft 5 drives the movable brush unit 6 to switch from the storage state to the deployment state. During the deployment of the movable brush unit 6, it will contact the inner wall of the fire extinguisher bottle 100 and stop deploying, and the movable brush unit 6 will follow the main shaft 5 in the circumferential movement along the inner wall of the fire extinguisher bottle 100 at the current deployment position. During this process, all the movable brush units 6 in the axial direction of the main shaft 5 will respectively scrub the inner wall of the fire extinguisher bottle 100 at the current position, thereby scrubbing the entire inner wall of the fire extinguisher bottle 100.

[0036] Through the technical solution of this embodiment, a main shaft 5 that can be extended into the interior of the fire extinguisher bottle 100 and multiple groups of movable brush units 6 are provided. These movable brush units 6 can automatically expand under the action of centrifugal force when the main shaft 5 rotates, and stop and reach the corresponding expanded state when they contact the inner wall of the fire extinguisher bottle 100; in this way, the centrifugal force is cleverly used to achieve the switching of the movable brush unit 6 between the expanded state and the stored state without adding a complicated mechanical structure, thereby simplifying the structure of the movable brush unit 6, and each movable brush unit 6 can automatically adapt to positions of different diameters, thereby achieving efficient cleaning of the fire extinguisher bottle 100.

[0037] Example 2 This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on the embodiment 1, a spray unit is added; See also Figure 4 , the cleaning mechanism 2 further includes a spraying unit, which is provided on the main shaft 5 and is used to spray cleaning liquid and water onto the inner wall of the fire extinguisher bottle 100; For details, please refer to Figure 5 The spraying unit includes a plurality of nozzles 802 and a delivery pipe 801. The plurality of nozzles 802 are provided at the top of the main shaft 5. The delivery pipe 801 is provided in the main shaft 5. One end of the delivery pipe 801 is connected to the nozzle 802, and the other end of the delivery pipe 801 can be connected to an external liquid supply device. In this embodiment, the structures of the delivery pipe 801 and the nozzle 802 can both be selected from products available on the market. The liquid supply device can be a structure in the existing technology, such as a combination of a liquid tank and a pump. The cleaning liquid can be selected from products available on the market, mainly to improve the cleaning effect of the inner wall of the fire extinguisher bottle 100. Tap water can be used as clean water, which is mainly used to rinse the inner wall of the fire extinguisher bottle 100 after being washed with the cleaning liquid; a convenient detachable connection structure is adopted between the delivery pipe 801 and the liquid supply device. The convenient detachable connection technology is relatively mature in this field and will not be given in detail here. When it is necessary to spray cleaning liquid and clean water, the delivery pipe 801 is connected to the liquid supply device. When the main shaft 5 rotates to drive the movable brush unit 6 to wash the inner wall of the fire extinguisher bottle 100, the delivery pipe 801 is separated from the liquid supply device, and the delivery pipe 801 and the nozzle 802 move together with the main shaft 5.

[0038] In this embodiment, please refer to Figure 5 A drainage groove 9 is provided on the bottom surface of the positioning groove 301, and the drainage groove 9 is connected to the cleaning groove 101. The cleaning liquid and clean water inside the fire extinguisher bottle 100 can flow out from the opening of the fire extinguisher bottle 100 through the drainage groove 9 into the cleaning groove 101 after flushing the inner wall of the fire extinguisher bottle 100. A drainage structure is provided in the cleaning groove 101 for discharging the collected liquid; Through the technical solution of this embodiment, the operator can spray cleaning liquid and clean water into the fire extinguisher bottle 100 at an appropriate time, which can improve the cleaning effect of the fire extinguisher bottle 100. At the same time, the convenient detachable connection between the delivery pipe 801 and the liquid supply device will not affect the cleaning of the inner wall of the fire extinguisher bottle 100 by the main shaft 5 and the movable brush unit 6, thereby ensuring efficient cleaning of the fire extinguisher bottle 100.

[0039] Example 3 This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on the first and / or second embodiments, a structure of a clamping unit is further disclosed, which clamps the fire extinguisher bottle 100 by air pressure adsorption. In this embodiment, please refer to Figure 5 The clamping unit includes: a gas flow channel 401, a plurality of adsorption holes 402, The gas flow channel 401 is provided in the base 3, and one end of the gas flow channel 401 can be connected to an external air extraction device. The air extraction device can be a structure in the prior art, such as a compressor or an air pump; A plurality of adsorption holes 402 are spaced apart and provided in the positioning groove 301 , and the adsorption holes 402 are connected to the other end of the gas flow channel 401 ; In this embodiment, after the open end of the fire extinguisher bottle 100 is positioned in the positioning groove 301, the outer wall of the open end of the fire extinguisher bottle 100 is in contact with the side wall of the positioning groove 301 and blocks the adsorption hole 402. At this time, one end of the gas flow channel 401 is connected to the exhaust device, which is activated to extract the air in the gas flow channel 401 and the adsorption hole 402, forming a negative pressure to suck the open end of the fire extinguisher bottle 100, thereby completing the clamping of the fire extinguisher bottle 100. In this embodiment, multiple adsorption holes 402 are distributed in the positioning groove 301 at intervals along the circumferential direction and the axial direction, so that when the fire extinguisher bottle 100 is clamped, a relatively uniform suction force can be generated at various positions of the outer wall of the open end of the fire extinguisher bottle 100, thereby ensuring the stability of the fire extinguisher bottle 100 during the cleaning process.

[0040] Example 4 This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on the embodiment 1 and / or embodiment 2 and / or embodiment 3, a structure of the movable brush unit 6 is also disclosed. In this embodiment, the movable brush unit 6 includes: a mounting plate 601, a swing arm 602, an elastic telescopic member 604, See also Figure 6 Each set of movable brush units 6 includes two parallel mounting plates 601. The mounting plates 601 are coaxially connected to the main shaft 5. When the main shaft 5 rotates, the mounting plates 601 rotate coaxially. Figure 7 and Figure 8What is shown is the structure after the movable brush unit 6 hides a mounting plate 601; The first end of the swing arm 602 is rotatably connected to the mounting plate 601, and the second end of the swing arm 602 is provided with a soft brush 603. When the mounting plate 601 rotates, the second end of the swing arm 602 can swing toward the outside of the mounting plate 601 under the action of centrifugal force, so that the movable brush unit 6 is in an expanded state. The soft brush 603 can be a commercially available product. After the movable brush unit 6 is expanded inside the fire extinguisher bottle 100, the soft brush 603 contacts the inner wall of the fire extinguisher bottle 100. A plurality of swing arms 602 can be provided, and the plurality of swing arms 602 are distributed at intervals along the circumference of the mounting plate 601. Please refer to Figure 7 In this embodiment, two swing arms 602 are used as an example. According to the orientation sequence in the figure, when the main shaft 5 rotates counterclockwise with the mounting plate 601, the second ends of the two swing arms 602 will swing toward the outside of the mounting plate 601 with the first ends as the fulcrum under the action of centrifugal force, that is, the movable brush unit 6 is deployed; The elastic member 604 is connected to the swing arm 602 and the mounting plate 601 respectively. When the swing arm 602 is not subjected to the centrifugal force, the elastic member 604 can hide the second end of the swing arm 602 in the mounting plate 601 so that the movable brush unit 6 is in a storage state. The elastic member 604 can be a structure in the prior art that can deform when subjected to force and return to its original shape after the external force is removed, such as a spring, a rubber product, etc. In this embodiment, a spring is used as an example. When the main shaft 5 rotates with the mounting plate 601, the centrifugal force on the swing arm 602 needs to overcome the elastic force of the spring before it can be deployed. That is, when the rotation speed of the main shaft 5 is very low, the swing arm 602 will not be deployed, thereby preventing the movable brush unit 6 from being accidentally deployed during transportation. As for the parameters such as the required length and stiffness coefficient of the spring, as well as the minimum rotation speed of the main shaft 5, they can be obtained through experiments during actual design. When selecting the rotation speed of the main shaft 5, it is necessary to ensure that the overall diameter of the movable brush unit 6 in the expanded state is larger than the maximum diameter of the inner wall of the fire extinguisher bottle 100, so that the movable brush unit 6 can automatically adapt to the different inner walls of the fire extinguisher bottle 100.

[0041] Through the technical solution of this embodiment, when the centrifugal force exerted on the swing arm 602 on the mounting plate 601 is greater than the elastic force of the elastic telescopic part 604, it will swing and expand to the outside of the mounting plate 601, so that the soft brush 603 can contact the inner wall of the fire extinguisher bottle 100 to clean the fire extinguisher bottle 100. When the centrifugal force exerted on the swing arm 602 on the mounting plate 601 is less than the elastic force of the elastic telescopic part 604, it will be pulled back to the mounting plate 601 by the elastic telescopic part 604 until it is hidden, thereby realizing the automatic switching of the movable brush unit 6 between the expanded state and the stored state, with a clever structure and easy maintenance.

[0042] Example 5 This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on the embodiment 4, the movable brush unit 6 is improved; In this embodiment, the movable brush unit 6 further includes a locking groove 605 and a swing locking member 606; See also Figure 9 , the locking slot 605 is provided at the second end of the swing arm 602; One end of the swing locking member 606 is rotatably connected to the mounting plate 601, and the other end of the swing locking member 606 has a hook portion, which can be engaged with and withdrawn from the locking groove 605 during the swinging process of the swing locking member 606. When the hook portion is engaged with the locking groove 605, the swing arm 602 can be locked in the mounting plate 601, and when the hook portion is withdrawn from the locking groove 605, the swing arm 602 can be unlocked. Figure 9-10 What is shown is a schematic diagram of two swing arms 602, one swing arm 602 is in a stored state and locked, and the other swing arm 602 is in an expanded state. In this case, the main shaft 5 drives the mounting plate 601 to rotate, and only drives the unlocked swing arm 602 to expand. In this way, when multiple swing arms 602 are provided and one of them or the mechanism swing arm 602 is damaged, the damaged swing arm 602 can be locked, and the remaining swing arms 602 are in an unlocked state, so that the movable brush unit 6 can still be used normally; in addition, when the movable brush unit 6 is transported or one or more movable brush units 6 on the main shaft 5 is inspected, it is only necessary to unlock the swing arm 602 in the movable brush unit 6 that needs to be expanded, and lock the remaining swing arms 602, so that the movable brush unit 6 that does not need to be expanded will not interfere with the corresponding transportation or inspection.

[0043] For details, please refer to Figure 9, a fixed column 607 is provided on the mounting plate 601, one end of the swing locking member 606 is sleeved on the fixed column 607, and a torsion elastic member 608 is sleeved on the fixed column 607. When the swing locking member 606 swings relative to the fixed column 607, the torsion elastic member 608 is squeezed. The torsion elastic member 608 can be selected from the prior art. When subjected to torque, it will be twisted and deformed, and after the external force is removed, it will try to restore its original shape, such as a torsion spring. An electromagnetic unit 609 is provided on the mounting plate 601 and on the side of the swing locking member 606 away from the locking groove 605. The electromagnetic unit 609 can be selected In the prior art, a structure that generates magnetism when powered on and loses magnetism when powered off, such as an electromagnet, is used. A metal block that can be attracted by the electromagnetic force is provided on the swing lock member 606. When powered on, the electromagnetic unit 609 can attract the metal block on the swing lock member 606, thereby driving the swing lock member 606 to swing away from the swing arm 602 and out of the locking groove 605. During this process, the torsional elastic member 608 is twisted and deformed by the torque. When the electromagnetic unit 609 is powered off, the metal block is no longer attracted, and the torsional elastic member 608 returns to its original shape and swings the swing lock member 606 toward the swing arm 602. In this embodiment, through the cooperation of the electromagnetic unit 609 and the torsion elastic member 608, the swing arm 602 can be automatically locked and unlocked by simply controlling the power on and off of the electromagnetic unit 609, which simplifies the operation of the operator and further improves the overall structural stability of the movable brush unit 6; in addition, when the electromagnetic unit 609 is not energized, the swing locking member 606 is in a state of locking the swing arm 602, and the electromagnetic unit 609 only needs to be briefly energized when the fire extinguisher bottle 100 needs to be cleaned, which consumes less energy and is more environmentally friendly.

[0044] Example 6 This embodiment provides a method for using a cleaning device for processing fire extinguisher bottles. The method is applicable to the cleaning device in Example 4 and / or Example 5. The method includes the following steps: Positioning the fire extinguisher bottle 100: Place the open end of the fire extinguisher bottle 100 downward so that the main shaft 5 and the movable brush unit 6 enter the fire extinguisher bottle 100, and place the open end of the fire extinguisher bottle 100 into the positioning groove 301 so that the outer wall of the fire extinguisher bottle 100 blocks the adsorption hole 402 to complete the positioning of the fire extinguisher bottle 100; Clamping the fire extinguisher bottle 100: Connect the gas flow channel 401 to the air extraction device, start the air extraction device to generate negative pressure in the gas flow channel 401 and the adsorption hole 402, and suck the positioned fire extinguisher bottle 100 to complete the clamping of the fire extinguisher bottle 100; Cleaning liquid spraying: activating the spraying unit to spray the cleaning liquid from top to bottom inside the fire extinguisher bottle 100; Cleaning: The power source 7 is started to drive the main shaft 5 to rotate, and the main shaft 5 drives the mounting plate 601 to rotate. The second end of the swing arm 602 generates centrifugal force on the mounting plate 601 and overcomes the elastic force of the elastic elastic member 604 to swing toward the outside of the mounting plate 601. Finally, the soft brush 603 at the second end of the swing arm 602 contacts the inner wall of the fire extinguisher bottle 100 and moves along the circumference of the fire extinguisher bottle 100, thereby cleaning the inner wall of the fire extinguisher bottle 100. Clean water spraying: Start the spraying unit to spray clean water from top to bottom inside the fire extinguisher bottle 100; Release the fire extinguisher bottle 100: turn off the power source 7 to switch the movable brush unit 6 to the storage state, connect the gas flow channel 401 to the atmosphere, and remove the fire extinguisher bottle 100 from the base 3; When the cleaning device of Example 4 is used, the movable brush unit 6 does not need to be adjusted when the fire extinguisher bottle 100 is positioned. When the cleaning device of Example 5 is used, the swing arm 602 that can be normally used can be unlocked when the fire extinguisher bottle 100 is positioned, or the swing arm 602 that can be normally used can be unlocked after the fire extinguisher bottle 100 is clamped. After the cleaning liquid spraying step, a washing step is required. After the first washing step, a clean water spraying step should generally be performed. After the clean water spraying step, a washing step is also required. The clean water spraying step and the washing step need to be performed consecutively for multiple times, generally two to three times, mainly to ensure that no cleaning liquid remains on the inner wall of the fire extinguisher. During the release step of the fire extinguisher bottle 100, the gas flow channel 401 can be connected to the atmosphere by separating the gas channel from the exhaust device. Through the method of using the cleaning device for processing fire extinguisher bottles in this embodiment, the overall structure of the cleaning device is simplified, the steps that the operator needs to perform in the process of cleaning the fire extinguisher bottle 100 are reduced, and a large number of properties of the object itself, such as inertia and centrifugal force, are used to achieve efficient cleaning of the fire extinguisher bottle 100, while saving energy and being more environmentally friendly.
