Description

Technical Field

[0001] This invention belongs to the field of fire extinguisher processing technology, and particularly relates to a cleaning device for processing fire extinguisher bottles and its usage method. Background Technology

[0002] The fire extinguisher bottle is the main part of the fire extinguisher. During the processing of the fire extinguisher bottle, it needs to be cleaned to remove dirt and impurities inside the bottle, so as 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 bottles, including a clamping component for fixing the fire extinguisher cylinder. The clamping component can drive the fire extinguisher cylinder to move and insert the fire extinguisher cylinder into the cleaning component. The cleaning component is installed at the lower end of the clamping component. The upper end of the cleaning component is provided with a spray head with multiple adjustable angles and a drying head with multiple adjustable trajectories. The middle section of the cleaning component is provided with a stirring fan blade for stirring the cleaning agent. The bottom end of the cleaning component is provided with a water pump for recycling and filtering the cleaning agent.

[0004] In this technology, the extension and retraction of the stirring blades are achieved through the transmission and coordination of structures such as a telescopic motor, gear two, gear one, rotating disk, limiting groove, and sliding block. Therefore, a relatively complex structure needs to be set in each cleaning component. Once the transmission and coordination between these structures is damaged or malfunctions, the repair is quite troublesome. In addition, since the diameter of the mouth of the fire extinguisher bottle is different from the diameter of other parts, the extension distance of the stirring blades at the mouth of the fire extinguisher bottle is different from that of other parts. This requires the operator to control and adjust it individually, which is quite troublesome. Therefore, this technology needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a cleaning device and its method for processing fire extinguisher bottles. This device utilizes the centrifugal force generated during the rotation of the carrier to switch the soft brush between an extended and retracted state, and can automatically adapt to the extension distance of the soft brush. This simplifies the overall structure of the cleaning device and improves the cleaning efficiency of fire extinguisher bottles.

[0006] In view of this, the present invention provides a cleaning apparatus for processing fire extinguisher bottles, comprising:

[0007] The device body has several cleaning tanks, and each cleaning tank is equipped with a cleaning mechanism.

[0008] The cleaning facilities include:

[0009] The base has a positioning groove for positioning the open end of the fire extinguisher bottle.

[0010] The clamping unit is used to clamp the positioned fire extinguisher bottle;

[0011] The main shaft is rotatably mounted in a positioning groove, and multiple sets of movable brush units are provided on the main shaft along the axial direction.

[0012] The power source is used to drive the spindle to rotate;

[0013] When the main shaft rotates, the movable brush unit can switch to the unfolded state under the action of centrifugal force. When the main shaft is stationary, the movable brush unit switches to the retracted state. The main shaft and the movable brush unit in the retracted state can extend into the interior of the fire extinguisher bottle along the axial direction. When the movable brush unit is in the unfolded state, it can contact the inner wall of the fire extinguisher bottle.

[0014] In this technical solution, the open end of the fire extinguisher bottle is passed through the main shaft and multiple retracted movable brush units and placed into the positioning slot. At this time, the fire extinguisher bottle is clamped by the clamping unit, making the fire extinguisher bottle coaxial with the main shaft. Then, the power source is started to drive the main shaft to rotate, causing the movable brush units to switch to the unfolded state under the action of centrifugal force. In the unfolded state, the movable brush units scrub the inner wall of the fire extinguisher bottle. After the scrubbing is completed, the power source is turned off, the main shaft stops rotating, the movable brush units switch to the retracted state, and the clamping unit releases the fire extinguisher bottle. At this time, the fire extinguisher bottle can be removed to complete the cleaning.

[0015] In the above technical solution, the cleaning mechanism further includes a spraying unit, which is located on the main shaft and is used to spray cleaning fluid and clean water onto the inner wall of the fire extinguisher bottle.

[0016] In the above technical solution, the spraying unit further includes multiple nozzles and a delivery pipe. The multiple nozzles are mounted on the main shaft, and the delivery pipe is located 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.

[0017] In the above technical solution, a drainage groove is further provided on the bottom surface of the positioning groove, and the drainage groove is connected to the cleaning groove.

[0018] In the above technical solution, the clamping unit further includes:

[0019] Gas flow channel, which is set in the base, and one end of the gas flow channel can be connected to an external air extraction device;

[0020] Multiple adsorption holes are spaced apart in the positioning groove, and the adsorption holes are connected to the other end of the gas flow channel.

[0021] In the above technical solution, the active brush unit further includes:

[0022] Mounting plate, which is coaxially connected to the spindle;

[0023] The swing arm has a first end that is rotatably connected to the mounting plate, and a soft brush at the second end of the swing arm. When the mounting plate rotates, the second end of the swing arm can swing outward under the action of centrifugal force, so that the movable brush unit is in the unfolded state.

[0024] The elastic telescopic component connects the swing arm and the mounting plate respectively. When the swing arm is not subjected to centrifugal force, the elastic telescopic component can hide the second end of the swing arm in the mounting plate, so that the movable brush unit is in a retracted state.

[0025] In the above technical solution, the active brush unit further includes:

[0026] A locking groove is provided at the second end of the swing arm;

[0027] The swing locking component has one end rotatably connected to the mounting plate, and the other end has a hook. The hook can engage and disengage from the locking groove during the swinging process of the swing locking component. When the hook engages in the locking groove, it can lock the swing arm in the mounting plate. When the hook disengages from the locking groove, it can release the lock on the swing arm.

[0028] In the above technical solution, the mounting plate is further provided with a fixed post, one end of the swing locking member is sleeved on the fixed post, and a torsional elastic member is sleeved on the fixed post. When the swing locking member swings relative to the fixed post, it will squeeze the torsional elastic member. An electromagnetic unit is provided on the mounting plate and on the side of the swing locking member away from the locking groove. When the electromagnetic unit is energized, it can drive the swing locking member to exit the locking groove.

[0029] This invention also discloses a method for using a cleaning device for processing fire extinguisher bottles, applicable to the aforementioned cleaning device, comprising the following steps:

[0030] Fire extinguisher bottle positioning: With the open end of the fire extinguisher bottle facing down, the main shaft and movable brush unit enter the fire extinguisher bottle, and the open end of the fire extinguisher bottle is placed into the positioning groove, so that the outer wall of the fire extinguisher bottle blocks the suction hole to complete the positioning of the fire extinguisher bottle.

[0031] Fire extinguisher bottle clamping: Connect the gas flow channel to the suction device, start the suction device to generate negative pressure in the gas flow channel and suction hole, and suck up the positioned fire extinguisher bottle to complete the fire extinguisher bottle clamping.

[0032] Cleaning fluid spraying: Activate the spraying unit to spray cleaning fluid from top to bottom inside the fire extinguisher bottle;

[0033] Washing: Start the power source to drive the main shaft to rotate. 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 component to swing outward from 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.

[0034] Water spraying: Activate the spraying unit to spray water from top to bottom inside the fire extinguisher bottle;

[0035] Fire extinguisher bottle release: Turn off the power source to switch the moving brush unit to the storage state, connect the gas flow channel to the atmosphere, and remove the fire extinguisher bottle from the base.

[0036] The beneficial effects of this invention are:

[0037] 1. By setting a main shaft that can extend into the fire extinguisher bottle and multiple sets of movable brush units, these movable brush units can automatically unfold under the action of centrifugal force when the main shaft rotates, until they stop when they contact the inner wall of the fire extinguisher bottle and reach the corresponding unfolded state. This ingenious use of centrifugal force can realize the switching between the unfolded and retracted states of the movable brush units without adding complicated mechanical structures, simplifying the structure of the movable brush units. Moreover, each movable brush unit can automatically adapt to different diameter positions, achieving efficient cleaning of the fire extinguisher bottle.

[0038] 2. By setting a spraying unit on the main shaft, the spraying unit can spray cleaning fluid and clean water into the fire extinguisher bottle. This, in conjunction with the scrubbing of the movable brush unit, can improve the cleaning effect on the fire extinguisher bottle.

[0039] 3. By designing the clamping unit as a structure with a gas flow channel and multiple adsorption holes, when the open end of the fire extinguisher bottle is blocked by these adsorption holes, the connection between the gas flow channel and the suction device can generate negative pressure in the gas flow channel and adsorption holes, thereby adsorbing 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 does not require the addition of complicated mechanical structures to fix the fire extinguisher bottle, simplifying the structure of the cleaning device, reducing the overall size of the cleaning device, and lowering the environmental requirements for the use of the cleaning device.

[0040] 4. By designing the movable brush unit as a combination of a mounting plate, a swing arm, a soft brush, and an elastic telescopic component, the mounting plate rotates with the main shaft when the main shaft rotates. When the centrifugal force on the swing arm on the mounting plate is greater than the elastic force of the elastic telescopic component, it swings outward from the mounting plate, allowing the soft brush to contact the inner wall of the fire extinguisher bottle for cleaning. When the centrifugal force on the swing arm on the mounting plate is less than the elastic force of the elastic telescopic component, it is pulled back inward from the mounting plate until it is hidden. This achieves automatic switching between the extended and retracted states of the movable brush unit. The structure is ingenious and maintenance is convenient.

[0041] 5. By setting a locking groove on the swing arm and setting a movable swing locking component on the mounting plate to cooperate with the locking groove, the swing arm can be locked and unlocked. In this way, when moving the movable brush unit or repairing one or more movable brush units on the spindle, the movable brush unit that does not need to be unfolded will not interfere with the corresponding moving or repair. Furthermore, through the cooperation of the electromagnetic unit and the torsion elastic component, the swing arm can be automatically locked and unlocked simply by controlling the 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.

[0057] Fire extinguisher bottle

[0058] The structure of the fire extinguisher bottle 100 in this invention is as follows: Figure 3 As shown, the body of the fire extinguisher bottle 100 is a hollow cylindrical body. The diameter of the opening at the open end of the fire extinguisher bottle 100 is smaller than the diameter of the body of the fire extinguisher bottle 100. The opening end of the fire extinguisher bottle 100 and the body of the bottle are connected by an arc.

[0059] Example 1

[0060] This application provides a cleaning device for processing fire extinguisher bottles, including a device body 1.

[0061] Please see Figure 1 and Figure 2 The device body 1 has several cleaning tanks 101. The figure shows two cleaning tanks 101 as an example. Each cleaning tank 101 is equipped with a cleaning mechanism 2. A control box is provided on one side of the device body 1 to control the circuit part of the cleaning device. Figure 1 and Figure 2 Of the two cleaning mechanisms 2 shown, one cleaning mechanism 2 has a fire extinguisher bottle 100 positioned on it, while the other cleaning mechanism 2 does not have a fire extinguisher bottle 100.

[0062] Please see 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;

[0063] The base 3 is provided with a positioning groove 301 for positioning the open end of the fire extinguisher bottle 100. The bottom surface of the positioning groove 301 and the side wall are connected by an arc. The size of the positioning groove 301 is adapted to the open end of the fire extinguisher bottle 100.

[0064] The clamping unit is used to clamp the positioned fire extinguisher bottle 100. The clamping unit can clamp either the body of the fire extinguisher bottle 100 or its open end. The structure of the clamping unit can employ existing mechanical clamping methods, or other existing clamping methods such as pneumatic clamping, hydraulic clamping, or combined clamping. Figure 1 and Figure 2 The structure of the clamping unit is hidden inside;

[0065] The main shaft 5 is rotatably positioned 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.

[0066] Please see Figure 5 The power source 7 is located in the base 3 to drive the spindle 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 spindle 5. When the servo motor is started, it can drive the spindle 5 to rotate.

[0067] Multiple sets of movable brush units 6 are provided along the axial direction on the main shaft 5. Please refer to the section on the structure of the movable brush unit 6. Figure 6 When the main shaft 5 rotates, it enables the movable brush unit 6 to switch to the unfolded state under the action of centrifugal force. Figure 6 The movable brush unit 6 is in the unfolded state. In the unfolded 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 opening end of the fire extinguisher bottle 100. The main shaft 5 and the movable brush unit 6 in the retracted state can extend axially into the interior of the fire extinguisher bottle 100. In the unfolded state, the movable brush unit 6 can contact the inner wall of the fire extinguisher bottle 100.

[0068] In this embodiment, the operator positions the open end of the fire extinguisher bottle 100 toward the positioning groove 301 and axially places the fire extinguisher bottle 100 around the main shaft 5 and multiple sets of movable brush units 6 from the open end. Then, the bottle is positioned in contact with the positioning groove 301. The clamping unit then clamps the positioned fire extinguisher bottle 100. Next, the power source 7 is activated to drive the main shaft 5 to rotate. During the rotation, the main shaft 5 drives the movable brush units 6 to switch from the retracted state to the unfolded state. During the unfolding process, the movable brush units 6 will contact the inner wall of the fire extinguisher bottle 100 and stop unfolding. The movable brush units 6 will follow the main shaft 5 to move circumferentially along the inner wall of the fire extinguisher bottle 100 at the current unfolded position. During this process, all the movable brush units 6 along the axis of the main shaft 5 will wash the inner wall of the fire extinguisher bottle 100 at the current position, thereby washing the entire inner wall of the fire extinguisher bottle 100.

[0069] The technical solution of this embodiment includes a main shaft 5 that can extend into the fire extinguisher bottle 100 and multiple sets of movable brush units 6. When the main shaft 5 rotates, these movable brush units 6 can automatically unfold under the action of centrifugal force until they contact the inner wall of the fire extinguisher bottle 100 and stop to reach the corresponding unfolded state. This cleverly utilizes the action of centrifugal force without adding a complicated mechanical structure to realize the switching between the unfolded state and the retracted state of the movable brush units 6, simplifying the structure of the movable brush units 6. Moreover, each movable brush unit 6 can automatically adapt to different diameter positions, achieving efficient cleaning of the fire extinguisher bottle 100.

[0070] Example 2

[0071] This embodiment provides a cleaning device for processing fire extinguisher bottles, which adds a spraying unit based on embodiment 1;

[0072] Please see Figure 4 The cleaning mechanism 2 also includes a spraying unit, which is mounted on the main shaft 5 and is used to spray cleaning fluid and water onto the inner wall of the fire extinguisher bottle 100.

[0073] For details, please refer to Figure 5 The spraying unit includes multiple nozzles 802 and a delivery pipe 801. The multiple nozzles 802 are located on the top of the main shaft 5, and the delivery pipe 801 is located 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.

[0074] In this embodiment, the structures of the delivery pipe 801 and the nozzle 802 can both be commercially available products. The liquid supply device can be a structure from the prior art, such as a combination of a liquid tank and a pump. The cleaning liquid can be a commercially available product, mainly to improve the cleaning effect on the inner wall of the fire extinguisher bottle 100. Tap water can be used for rinsing the inner wall of the fire extinguisher bottle 100 after it has been washed with the cleaning liquid. The delivery pipe 801 and the liquid supply device adopt a convenient and detachable connection structure. The convenient and detachable connection technology is relatively mature in the field and will not be described 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 and drives 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.

[0075] In this embodiment, please refer to Figure 5 The bottom surface of the positioning groove 301 is provided with a drain groove 9, which is connected to the cleaning groove 101. After rinsing the inner wall of the fire extinguisher bottle 100, the cleaning liquid and water inside the fire extinguisher bottle 100 can flow out from the opening of the fire extinguisher bottle 100 and enter the cleaning groove 101 through the drain groove 9. The cleaning groove 101 is provided with a drain structure for draining the collected liquid.

[0076] Through the technical solution of this embodiment, the operator can spray cleaning fluid and clean water into the fire extinguisher bottle 100 at the appropriate time, which can improve the cleaning effect of the fire extinguisher bottle 100. At the same time, the convenient and detachable connection between the delivery pipe 801 and the liquid supply device will not affect the scrubbing of the inner wall of the fire extinguisher bottle 100 by the main shaft 5 and the movable brush unit 6, thus ensuring efficient cleaning of the fire extinguisher bottle 100.

[0077] Example 3

[0078] This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on Embodiment 1 and / or Embodiment 2, it also discloses a structure of a clamping unit that clamps the fire extinguisher bottle 100 by means of air pressure adsorption.

[0079] In this embodiment, please refer to Figure 5 The clamping unit includes: a gas flow channel 401 and multiple adsorption holes 402.

[0080] Gas flow channel 401 is provided in base 3. One end of 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.

[0081] Multiple adsorption holes 402 are spaced apart in the positioning groove 301, and the adsorption holes 402 are connected to the other end of the gas flow channel 401.

[0082] 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 attached to 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 air extraction device. The air extraction device is activated to extract the air in the gas flow channel 401 and the adsorption hole 402, forming a negative pressure to suck up the open end of the fire extinguisher bottle 100, thus completing the clamping of the fire extinguisher bottle 100.

[0083] In this embodiment, multiple adsorption holes 402 are distributed circumferentially and axially in the positioning groove 301, so that when the fire extinguisher bottle 100 is clamped, a relatively uniform suction force can be generated at various positions on 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.

[0084] Example 4

[0085] This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on Embodiment 1 and / or Embodiment 2 and / or Embodiment 3, a structure of the movable brush unit 6 is also disclosed.

[0086] In this embodiment, the movable brush unit 6 includes: a mounting plate 601, a swing arm 602, and an elastic telescopic member 604.

[0087] Please see Figure 6 Each set of movable brush units 6 includes two parallel mounting discs 601. The mounting discs 601 are coaxially connected to the main shaft 5. When the main shaft 5 rotates, it will cause the mounting discs 601 to rotate coaxially. Figure 7 and Figure 8 What is shown is the structure of the active brush unit 6 after hiding an installation disk 601;

[0088] The first end of the swing arm 602 is rotatably connected to the mounting plate 601. 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 outward under the action of centrifugal force, so that the movable brush unit 6 is in the unfolded state. The soft brush 603 can be a commercially available product. After the movable brush unit 6 is unfolded inside the fire extinguisher bottle 100, the soft brush 603 contacts the inner wall of the fire extinguisher bottle 100. Multiple swing arms 602 can be provided, and the multiple swing arms 602 are distributed at intervals along the circumference of the mounting plate 601. Please refer to [link to relevant documentation]. 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 end of the two swing arms 602 will swing outward from the mounting plate 601 with the first end as the fulcrum under the action of centrifugal force, that is, the movable brush unit 6 unfolds.

[0089] The elastic telescopic component 604 is connected to the swing arm 602 and the mounting plate 601 respectively. When the swing arm 602 is not subjected to centrifugal force, the elastic telescopic component 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 retracted state.

[0090] The elastic telescopic component 604 can be selected from existing technologies that can deform under force and return to their original shape after the external force is removed, such as springs, rubber products, 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 spring force to unfold. That is, when the rotation speed of the main shaft 5 is very low, the swing arm 602 will not unfold. This can prevent the movable brush unit 6 from being accidentally unfolded during transportation. As for the required spring length and stiffness coefficient, as well as the minimum rotation speed of the main shaft 5, they can be obtained by testing during actual design.

[0091] When selecting the rotational speed of the main shaft 5, it is necessary to ensure that the overall diameter of the movable brush unit 6 in its unfolded state is greater than the maximum diameter of the inner wall of the fire extinguisher bottle 100. This is necessary to enable the movable brush unit 6 to automatically adapt to different inner walls of the fire extinguisher bottle 100.

[0092] Through the technical solution of this embodiment, when the centrifugal force on the swing arm 602 on the mounting plate 601 is greater than the elastic force of the elastic telescopic member 604, it will swing outward from 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 on the swing arm 602 on the mounting plate 601 is less than the elastic force of the elastic telescopic member 604, it will be pulled back inward from the mounting plate 601 by the elastic telescopic member 604 until it is hidden. In this way, the automatic switching between the extended state and the retracted state of the movable brush unit 6 is realized. The structure is ingenious and the maintenance is convenient.

[0093] Example 5

[0094] This embodiment provides a cleaning device for processing fire extinguisher bottles. Based on embodiment 4, the movable brush unit 6 has been improved.

[0095] In this embodiment, the movable brush unit 6 further includes a locking groove 605 and a swing locking member 606;

[0096] Please see Figure 9 The locking groove 605 is located at the second end of the swing arm 602;

[0097] 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. The hook can engage and disengage from the locking groove 605 during the swinging process of the swing locking member 606. When the hook engages in the locking groove 605, it can lock the swing arm 602 in the mounting plate 601. When the hook disengages from the locking groove 605, it can release the lock on the swing arm 602.

[0098] Figures 9-10 The diagram shows a setup with two swing arms 602, one in a retracted and locked state and the other in an extended state. In this configuration, the spindle 5 rotates the mounting plate 601, which only causes the unlocked swing arm 602 to extend. Therefore, if multiple swing arms 602 are present and one or more swing arms 602 are damaged, the damaged swing arm 602 can be locked while the remaining swing arms 602 remain unlocked, allowing the movable brush unit 6 to still function normally. Furthermore, when moving the movable brush unit 6 or repairing one or more movable brush units 6 on the spindle 5, simply unlock the swing arm 602 in the movable brush unit 6 that needs to be extended, while locking the remaining swing arms 602. This prevents the movable brush unit 6 that does not need to be extended from interfering with the moving or repair process.

[0099] For details, please refer to Figure 9 The mounting plate 601 is provided with a fixed post 607. One end of the swing locking member 606 is sleeved on the fixed post 607. A torsion elastic member 608 is sleeved on the fixed post 607. When the swing locking member 606 swings relative to the fixed post 607, it will compress the torsion elastic member 608. The torsion elastic member 608 can be a structure that twists and deforms under torque and attempts to return to its original shape after the external force is removed, such as a torsion spring. An electromagnetic unit 609 is provided on the mounting plate 601 on the side of the swing locking member 606 away from the locking groove 605. The electromagnetic unit 609 can be selected from... Using existing technologies, structures that generate magnetism when energized and lose magnetism when de-energized, such as electromagnets, a metal block that can be attracted by electromagnetic force is provided on the swing locking member 606. When the electromagnetic unit 609 is energized, it can attract the metal block on the swing locking member 606, thereby driving the swing locking member 606 to swing away from the swing arm 602 and exit the locking groove 605. During this process, the torsional elastic member 608 is torn and deformed by torque. When the electromagnetic unit 609 is de-energized, the metal block is no longer attracted, the torsional elastic member 608 returns to its original shape and swings the swing locking member 606 towards the swing arm 602.

[0100] In this embodiment, through the cooperation of the electromagnetic unit 609 and the torsion elastic element 608, the automatic locking and unlocking of the swing arm 602 can be achieved simply by controlling the 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 element 606 is in the locked swing arm 602 state. 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.

[0101] Example 6

[0102] This embodiment provides a method of using a cleaning device for processing fire extinguisher bottles. This method is applicable to the cleaning devices in Embodiments 4 and / or 5, and includes the following steps:

[0103] Positioning of fire extinguisher bottle 100: With the open end of the fire extinguisher bottle 100 facing down, the main shaft 5 and the movable brush unit 6 enter the fire extinguisher bottle 100, and the open end of the fire extinguisher bottle 100 is placed 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.

[0104] Fire extinguisher bottle 100 clamping: 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 suction hole 402, and suck up the positioned fire extinguisher bottle 100 to complete the clamping of the fire extinguisher bottle 100.

[0105] Cleaning fluid spraying: Activate the spraying unit to spray cleaning fluid from top to bottom inside the fire extinguisher bottle 100;

[0106] Washing: The power source 7 is started to drive the main shaft 5 to rotate. 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 telescopic member 604 to swing outward from 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 washing the inner wall of the fire extinguisher bottle 100.

[0107] Water spraying: Activate the spraying unit to spray water from top to bottom inside the fire extinguisher bottle 100;

[0108] Fire extinguisher bottle 100 release: Turn off power source 7 to switch the active brush unit 6 to the storage state, connect gas flow channel 401 to the atmosphere, and remove fire extinguisher bottle 100 from base 3.

[0109] When the cleaning device of Embodiment 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 Embodiment 5 is used, the normally usable swing arm 602 can be unlocked when the fire extinguisher bottle 100 is positioned, or the normally usable swing arm 602 can be unlocked after the fire extinguisher bottle 100 is clamped.

[0110] After the cleaning solution spraying step, a washing step is required. After the first washing step, a water spraying step should generally be performed, followed by another washing step. The water spraying and washing steps need to be repeated multiple times, generally two to three times, mainly to ensure that no cleaning solution remains on the inner wall of the fire extinguisher. In the fire extinguisher bottle 100 release step, the gas flow channel 401 can be connected to the atmosphere by separating the gas channel from the extraction device.

[0111] The method of using the cleaning device for fire extinguisher bottle processing in this embodiment simplifies the overall structure of the cleaning device, reduces the number of steps that operators need to take during the cleaning of fire extinguisher bottle 100, and utilizes many properties of the object itself, such as inertia and centrifugal force, to achieve efficient cleaning of fire extinguisher bottle 100, while saving energy and being more environmentally friendly.

[0112] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
