[0066] Detailed Implementation

[0067] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0068] Figure 1 This is a structural schematic diagram of a vehicle-mounted fire extinguisher that is easy to disassemble and replace, according to one embodiment of the present invention. Figure 2 This is a cross-sectional view of a vehicle-mounted fire extinguisher that is easy to disassemble and replace, according to one embodiment of the present invention. Figure 1 and Figure 2 In this vehicle-mounted fire extinguisher, which is easy to disassemble and replace, it may include a tank 1, a limiting component, and a pressing component. Specifically, the tank 1 may include an extinguishing medium.

[0069] The tank body 1 contains extinguishing medium. The limiting component is U-shaped, and the tank body 1 is located inside the limiting component, i.e., inside the U-shape, and is detachably connected to the limiting component. The pressing component is located inside the limiting component and is connected to the spray pipe 14 of the tank body 1, and is used to press and drive the tank body 1 to spray the extinguishing medium / extinguishing agent.

[0070] When installing tank 1, open the limiting component and install tank 1 into the U-shape of the limiting component. After installation, the limiting component will lock and secure the tank, also fixing the spray pipe 14 of tank 1. When using tank 1 for fire extinguishing, press the activation component to drive the spray pipe 14 of tank 1 to spray the extinguishing medium, thus achieving the fire extinguishing operation. After the extinguishing medium inside tank 1 has been sprayed, and tank 1 needs to be replaced, open the limiting component and replace it with a new tank 1 as described above.

[0071] Traditional vehicle-mounted fire extinguishers are generally small in size, with a limited amount of extinguishing medium inside, and are typically disposable. However, after each use, a new vehicle-mounted fire extinguisher needs to be purchased, resulting in high costs and a long time required to reach standby status. In this embodiment of the invention, a combination of a limiting component and a pressing component enables safe and stable replacement and reliable use of the tank 1, reducing the frequency of overall fire extinguisher replacement and the number of discarded extinguishers. This invention only requires replacing the tank 1, thus reducing costs. Furthermore, the tank 1 is easy to replace, allowing for quicker replacement in emergency fire situations to achieve standby status. This structure improves maintenance efficiency and flexibility; for damaged tank 1, only the tank 1 needs to be replaced, whereas traditional methods require replacing the entire extinguishing device. In addition, the smaller size of the tank 1 effectively improves storage and transportation costs and convenience, meeting the safety requirements of different usage scenarios and offering wider applicability.

[0072] In this embodiment of the present invention, the type of the canister 1 may include a binary fire extinguisher. Specifically, the binary fire extinguisher may include a canister body, an extinguishing agent bag, a seal, and a spray pipe 14. The extinguishing agent bag is disposed inside the canister body, and the seal is disposed at the canister opening and seals the opening. The spray pipe 14 extends from the extinguishing agent bag, passes through the seal, and extends upward. Specifically, by repeatedly pressing the spray pipe 14, the extinguishing medium / extinguishing agent inside the extinguishing agent bag can be sprayed out along the spray pipe 14 due to the change in gas pressure inside the canister body. The structure and spraying principle of the binary fire extinguisher are technologies known to those skilled in the art and will not be described in detail here.

[0073] In this embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the limiting component may include a first limiting part, a second limiting part 6, and a third limiting part.

[0074] The first limiting part is located at the top of the tank body 1 and is detachably connected to the top of the tank body 1. The second limiting part 6 is located on the side wall of the tank body 1, and one end of the second limiting part 6 is connected to the first limiting part. The third limiting part is located at the bottom of the tank body 1, and the other end of the second limiting part 6 is locked to the third limiting part. Specifically, this locking connection means that the other end of the second limiting part 6 and the third limiting part can be locked to be relatively fixed, or they can be released from the lock to be loosened.

[0075] When it is necessary to install or replace tank 1, disengage the third limiting part from the second limiting part 6, then insert tank 1 along the side wall of the second limiting part 6 into the interior of the first limiting part and connect with it. After connection, fit the third limiting part against the bottom of tank 1 and lock it in place with the second limiting part 6, so that the third limiting part and the first limiting part cooperate to limit and fix tank 1. This cooperative limiting structure can effectively improve the convenience and flexibility of limiting and fixing tank 1.

[0076] In this embodiment of the present invention, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the first limiting part may include a top seat 3, a hollow column 19, a circular plate 25, and a snap-fit ​​assembly. Specifically, the top seat 3 may include a cavity 15 and a circular hole, the hollow column 19 may include a plurality of first limiting plates 26, and the circular plate 25 may include a tube column 24.

[0077] The top seat 3 has an internal cavity 15, and a circular hole communicating with the cavity 15 is formed at the bottom of the top seat 3. A hollow column 19 is disposed inside the cavity 15 and coaxially distributed with the circular hole. Multiple first limiting plates 26 are arranged around the inner circumference of the hollow column 19. A circular plate 25 is coaxially disposed inside the hollow column 19 and connected to the opposite ends of the multiple first limiting plates 26. A pipe column 24 is fixedly inserted through the center of the circular plate 25, and the injection pipe 14 extends into the interior of the pipe column 24. A snap-fit ​​assembly is disposed at the bottom end of the hollow column 19 for limiting and fixing the opening of the tank body 1.

[0078] During installation of the tank 1, the top of the tank 1 is passed through the circular hole, and the top part of the tank 1 enters the interior of the cavity 15. Simultaneously, the spray pipe 14 of the tank 1 extends into the interior of the tubing column 24 and is connected and fixed to the tank 1 using a snap-fit ​​assembly. By using the tubing column 24 to constrain the spray pipe 14, and by using the snap-fit ​​assembly to engage with the tank 1, stable confinement of the tank 1 is achieved, ensuring the reliability and stability of the spraying of the extinguishing medium from the spray pipe 14 of the tank 1.

[0079] In this embodiment of the present invention, the structure of the snap-fit ​​assembly can include various forms known to those skilled in the art, such as a top-to-bottom snap-fit ​​method where the snap-fit ​​post and the first snap-fit ​​groove 31 engage. However, in a preferred embodiment of the present invention, considering the convenience and stability of the snap-fit, the specific structure of the snap-fit ​​assembly can be as follows: Figure 3 and Figure 5 As shown. Specifically, in Figure 3 and Figure 5 In this assembly, the snap-fit ​​component may include multiple second limiting plates 27 and a first annular plate 23. Specifically, the second limiting plate 27 may include a first snap-fit ​​groove 31, and the first annular plate 23 may include multiple third limiting plates 33. Specifically, the third limiting plate 33 may include a first snap-fit ​​protrusion 32.

[0080] Multiple second limiting plates 27 are circumferentially arranged on the inner wall of the bottom end of the hollow column 19 and are staggered with multiple first limiting plates 26. The top of the second limiting plate 27 is provided with a first engaging groove 31. A first ring plate 23 is fixed to the outside of the tank opening of the tank body 1. Multiple third limiting plates 33 are circumferentially arranged on the top outer wall of the first ring plate 23. The bottom of the third limiting plate 33 is provided with a first engaging protrusion 32, which is used to engage with the first engaging groove 31. Specifically, the number of first engaging protrusions 32 and first engaging grooves 31 can include one or more sets. Multiple sets of first engaging protrusions 32 and first engaging grooves 31 are evenly arranged on the multiple third limiting plates 33 and the second limiting plates 27.

[0081] When connecting the tank body 1 to the top seat 3, firstly, a first ring plate 23 is fitted onto the outside of the tank opening of the tank body 1 and fixed with adhesive. Then, the multiple third limiting plates 33 on the first ring plate 23 are rotated to be misaligned with the multiple second limiting plates 27, meaning each third limiting plate 33 is positioned between two adjacent second limiting plates 27. At this point, the tank body 1 is moved upwards so that the spray pipe 14 enters the interior of the tube column 24 from the bottom end of the tube column 24. Simultaneously, the third limiting plates 33 enter along the gap between adjacent second limiting plates 27 until the bottom surface of the third limiting plate 33 is slightly higher than or flush with the top surface of the third limiting plate 33. The tank body 1 is rotated to drive the first ring plate 23 and the multiple third limiting plates 33 to rotate synchronously. The top of the third limiting plate 33 is engaged with the corresponding second limiting plate 27 until the first snap-fit ​​protrusion 32 engages with the corresponding first snap-fit ​​groove 31, thus achieving the installation and fixation of the tank body 1. When it is necessary to disassemble the tank body 1, simply rotate the tank body 1 so that the first snap-fit ​​protrusion 32 disengages from the corresponding first snap-fit ​​groove 31. The rotational snap-fit ​​method can effectively improve the stability of the connection between the tank body 1 and the top seat 3, and also improve the convenience of connecting and disassembling the tank body 1 and the top seat 3.

[0082] In this embodiment of the present invention, the vertical height of the first limiting plate 26 and the second limiting plate 27 may be greater than or equal to the thickness of the third limiting plate 33, but less than the sum of the thicknesses of the third limiting plate 33 and the first engaging protrusion 32. This ensures that when the third limiting plate 33 rotates, the first engaging protrusion 32 deforms until it engages with the first engaging groove 31, thereby effectively improving the engaging effect and further enhancing the stability of the connection between the tank 1 and the top seat 3. Therefore, the material of the first engaging protrusion 32 may include a deformable and restorable elastic material, etc.

[0083] In this embodiment of the present invention, the number of the first limiting plate 26, the second limiting plate 27, and the third limiting plate 33 can include various forms known to those skilled in the art, such as four or five. However, in a preferred example of the present invention, considering the stability of the structure and the convenience of snap-fit, the number of the first limiting plate 26, the second limiting plate 27, and the third limiting plate 33 can each include three.

[0084] In this embodiment of the present invention, the arc length of the first limiting plate 26 and the second limiting plate 27 located on the inner wall of the hollow column 19 may include the first limiting plate 26 being larger than the arc length of the second limiting plate 27, so that the third limiting plate 33 can be engaged with the second limiting plate 27 more quickly and conveniently, further improving the convenience of engagement.

[0085] In this embodiment of the present invention, the outer arc lengths of the second limiting plate 27 and the third limiting plate 33 may include the outer arc length of the third limiting plate 33 being greater than the outer arc length of the second limiting plate 27, so that the two ends of the third limiting plate 33 can fit / abut against the bottom of the two adjacent first limiting plates 26, thereby preventing the tank 1 from shaking and further improving the stability of the installation and fixing of the tank 1.

[0086] In this embodiment of the present invention, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the pressing assembly may include a pressing tube 28, a drive plate 20, a first through hole, a pressing plate 4, and a locking assembly. Specifically, the drive plate 20 may include a support portion 21.

[0087] The pressing tube 28 is positioned above the hollow column 19 and is L-shaped, comprising a horizontal section and a vertical section. The horizontal section of the pressing tube 28 extends movably through one side of the top seat 3, while the vertical section extends into the interior of the tube column 24 and engages with the injection tube 14 to press and spray. One end of the drive plate 20 is rotatably connected to the hollow column 19 and is located above the horizontal section of the pressing tube 28. A support portion 21 is provided at the bottom center of the drive plate 20, and the support portion 21 contacts and abuts against the top of the horizontal section of the pressing tube 28 near the vertical section. The first through hole is opened on the top and side of the top seat 3 away from the pressing tube 28, that is, at the corner of the top and side of the top seat 3 away from the pressing tube 28. If the pressing tube 28 passes through the left side of the top seat 3, the first through hole is located at the upper right corner of the top seat 3 and communicates with the interior of the cavity 15. The pressing plate 4 is arc-shaped, and the arc may include a horizontal section, a curved section, and a vertical section connected in sequence, with the curved section being the middle section. The pressing plate 4 is disposed inside the first through hole. The horizontal part of the pressing plate 4 is located at the top of the top seat 3, and the vertical part of the pressing plate 4 is located on the side of the top seat 3. The curved part of the pressing plate 4 is rotatably connected to the inner wall of the first through hole. One end of the pressing plate 4 abuts against the top of the other end of the drive plate 20, that is, the end of the horizontal part away from the curved part. The locking assembly is disposed on the side of the top seat 3 away from the pressing tube 28, and is used to press and limit the pressing plate 4.

[0088] When it is necessary to press the spray nozzle 14 to spray the extinguishing agent / extinguishing medium, the locking assembly is opened to disengage it from the locking plate 4. Then, the horizontal portion of the pressing plate 4 is pressed down. Because the curved portion of the pressing plate 4 is rotatably connected to the first through hole, the vertical portion of the pressing plate 4 rotates outward to cooperate with the downward movement of the horizontal portion. While the horizontal portion of the pressing plate 4 is pressed down, the other end of the drive plate 20 is simultaneously pressed, causing the support portion 21 to press down the vertical section of the pressing tube 28. The vertical section of the pressing tube 28 presses the spray nozzle 14 to spray the extinguishing medium. By using the pressing plate 4 and the drive plate 20 in conjunction to press the pressing tube 28, the purpose of stably spraying the extinguishing medium from the spray nozzle 14 can be achieved, and the operation is simple and convenient.

[0089] In this embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the end of the pressing tube 28 located outside the top seat 3 is provided with a spray head 2.

[0090] In this embodiment of the present invention, such as Figure 3 and Figure 5 As shown, in order to further improve the reliability and stability of the pressing tube 28, the side wall of the tube column 24 near the horizontal section of the pressing tube 28 is provided with a clearance notch, and the horizontal section of the pressing tube 28 is provided with a clearance hole on one side of the top seat 3.

[0091] In this embodiment of the present invention, such as Figure 3 As shown, a rotating seat is provided at one end of the drive plate 20. The rotating seat is rotatably connected to the top of the hollow column 19. One end of the drive plate 20 is fitted with the rotating seat and sleeved on the outside of the horizontal section of the pressing tube 28.

[0092] In this embodiment of the present invention, such as Figure 3 As shown, the vertical section of the pressing tube 28 may include an annular groove 22. The annular groove 22 is formed at the bottom end of the vertical section of the pressing tube 28 and on the inner wall of the tube hole. The radius of the spray tube 14 is larger than the radius of the tube hole of the vertical section and smaller than the radius of the annular groove 22. The spray tube 14 extends into the interior of the annular groove 22 and contacts and abuts against the inner bottom of the annular groove 22. With this structure, when the support 21 presses down on the vertical section of the pressing tube 28, the spray tube 14 can be pressed simultaneously by the limiting effect of the annular groove 22 to achieve the spraying of the extinguishing medium.

[0093] In this embodiment of the present invention, such as Figure 4 As shown, the drive plate 20 may further include an L-shaped plate 30, which is disposed at one end of the drive plate 20, that is, the end of the horizontal portion away from the curved portion. The horizontal section of the L-shaped plate 30 contacts and abuts against the top of the other end of the drive plate 20. The L-shaped plate 30 can further improve the ease of pressing.

[0094] In this embodiment of the present invention, such as Figure 4 As shown, the top of the pressing plate 4 is provided with multiple sets of anti-slip protrusions 29, that is, the top of the horizontal part is provided with multiple sets of anti-slip protrusions 29, which can effectively improve the pressing effect.

[0095] In this embodiment of the present invention, such as Figure 6 As shown, the locking assembly may include a second through hole, a sliding plate 5, a first limiting groove 37, a limiting block 38, and a fixing plate 34. Specifically, the sliding plate 5 may include a plurality of second snap-fit ​​grooves 36, and the fixing plate 34 may include second snap-fit ​​protrusions 35.

[0096] The second through hole is located on the side of the top seat 3 away from the pressing tube 28, below the first through hole, and communicates with the cavity 15. The slide plate 5 is slidably disposed inside the second through hole, located at the other end of the bottom of the pressing plate 4, i.e., the vertical part. The slide plate 5 has multiple vertically distributed second engaging grooves 36 on the side near the cavity 15. The first limiting groove 37 is located at the other end of the pressing plate 4, i.e., the bottom end of the vertical part. The limiting block 38 is disposed at the end of the slide plate 5 near the pressing plate 4, and the limiting block 38 is used to cooperate with the first limiting groove 37 for limiting. The fixing plate 34 is disposed inside the cavity 15. The fixing plate 34 has a second engaging protrusion 35 on the side near the slide plate 5 that engages with the second engaging grooves 36.

[0097] When the press plate 4 needs to be pressed, push the slide plate 5 upwards so that the limiting block 38 enters the first limiting groove 37 and helps to limit the rotation of the press plate 4. At the same time, the second engaging groove 36 and the second engaging protrusion 35 on the slide plate 5 at the bottom engage and fix it, thus achieving stable limitation of the press plate 4. Conversely, when the press plate 4 needs to be pressed, push the slide plate 5 downwards so that the limiting block 38 disengages from the first limiting groove 37, and at the same time, the second engaging groove 36 and the second engaging protrusion 35 at the top engage. By using the limiting block 38 and the first limiting groove 37 to limit the rotation of the press plate 4, the accidental pressing can be effectively prevented, improving the safety and reliability of the fire extinguisher, and the operation is simple.

[0098] In this embodiment of the present invention, such as Figure 7 As shown, the third limiting part may include a base 43, a bottom plate 40, a second limiting groove 42, and a fourth limiting plate 41. Specifically, the bottom plate 40 may include a second ring plate 13.

[0099] The base 43 is located at the bottom of the second limiting part 6. One end of the base plate 40 is rotatably connected to the base 43, and a second ring plate 13 is provided on the top of the base plate 40. The second limiting groove 42 is opened at the bottom of the base plate 40 near the end of the base 43. One end of the fourth limiting plate 41 is rotatably connected to the base 43, and the other end of the fourth limiting plate 41 is used to limit and cooperate with the second limiting groove 42.

[0100] When tank 1 needs to be installed, rotate the fourth limiting plate 41 to move it out of the second limiting groove 42. At this time, the bottom plate 40 is no longer restrained, and rotate it downwards to make way for the top of tank 1 to be installed. After the top of tank 1 is installed, rotate the bottom plate 40 to fit against the bottom of tank 1, and then rotate the fourth limiting plate 41 into the second limiting groove 42 to limit and fix the bottom plate 40. The method of using the bottom plate 40 and the top seat 3 to limit the tank 1 can further improve the stability of tank 1 installation. At the same time, the second ring plate 13 can protect and limit the lower side wall of tank 1, effectively protecting the bottom of tank 1.

[0101] In this embodiment of the present invention, such as Figure 1 As shown, the top seat 3 and the second limiting part 6 are provided with a handle hole 7, which makes it easy to pick up and carry, and also makes it easy to press with the horizontal part of the pressing plate 4.

[0103] In this embodiment of the present invention, such as Figure 8 , Figure 9 As shown, the fire extinguisher may also include a housing 9, a window breaker 18, an annular groove 52, and an annular cover 12. Specifically, the window breaker 18 may include a pressure cap 49 and a housing 48, etc. The specific structure and principle of the window breaker 18 are known to those skilled in the art and will not be described in detail here. The annular groove 52 may include multiple third snap-fit ​​grooves 51, and the annular cover 12 may include multiple third snap-fit ​​protrusions 50.

[0104] One side of the housing 9 is magnetically connected to the side of the second limiting part 6 away from the tank 1. The pressure cap 49 of the window breaker 18 is movably inserted through the bottom of the housing 9. The outer shell 48 of the window breaker 18 is connected to the inner bottom of the housing 9 and is fitted over the outer side of the pressure cap 49. An annular groove 52 is formed at the bottom edge of the housing 9, and the inner wall of the annular groove 52 is provided with multiple third snap-fit ​​grooves 51. An annular cover 12 is fitted over the outer side of the pressure cap 49, and one end extends into the interior of the annular groove 52. The inner wall of the annular cover 12 is provided with multiple third snap-fit ​​protrusions 50 that engage with the third snap-fit ​​grooves 51.

[0105] When the window breaker 18 is needed, the annular cover 12 is opened to expose the pressure cap 49. The end of the pressure cap 49 is then brought into contact with the glass window, and the housing 9 is pulled. Because the housing is connected to the inner bottom of the housing 9, the striking pin inside the housing is compressed, and finally the striking pin extends along the opening of the pressure cap 49 to break the glass window, thus achieving the purpose of breaking the window. The housing 9 is magnetically attached to the second limiting part 6, facilitating the disassembly and installation of the housing 9, and thus facilitating the use of the window breaker 18.

[0106] In this embodiment of the present invention, the magnetic attraction between the box body 9 and the second limiting part 6 may include providing a magnet 46 or a metal plate on the side of the second limiting part 6 away from the tank body 1, and the inner wall of the box body 9 is provided with a magnet 46 that cooperates with the magnet 46 or the metal plate on the side of the second limiting part 6 for magnetic attraction.

[0107] In this embodiment of the present invention, such as Figure 8 and Figure 10 As shown, the fire extinguisher may also include a knife hole, a V-shaped seat 11, a plurality of fourth locking slots, and a plurality of fourth locking protrusions 39.

The V-shaped seat 11 includes two plate segments, and the included angle formed by the two plate segments is rotatably connected to the inner wall of the tool hole. A tool 47 is disposed inside the V-shaped seat 11. Multiple fourth engaging grooves are respectively formed on the side walls of the two plate segments forming the included angle in the V-shaped seat 11. Multiple fourth engaging protrusions 39 are disposed inside the tool hole for engaging with one of the plate segments.

[0109] When a tool needs to be retrieved and used, move one of the plate segments of the V-shaped base 11 along the tool hole to disengage the fourth locking groove of that plate segment from the corresponding fourth locking protrusion 39. Simultaneously, continue rotating the V-shaped base 11 so that the fourth locking groove of the other plate segment engages with the corresponding fourth locking protrusion 39 and is then secured. The tool located inside the V-shaped base 11 can then be retrieved. Conversely, when a tool needs to be stored, push the V-shaped base 11 in the opposite direction to disengage the fourth locking groove of the other plate segment from the corresponding fourth locking protrusion 39, allowing the fourth locking groove of one plate segment to engage with the corresponding fourth locking protrusion 39. This method of using the V-shaped base 11 and its locking mechanism makes it easier to use and store the tool 47.

[0110] In this embodiment of the present invention, such as Figure 10 As shown, in order to further improve the convenience of taking out the knife 47, a clearance groove 45 is provided on the top of one of the plates of the V-shaped base 11 near the inside of the housing 9.

[0111] In this embodiment of the present invention, such as Figure 2 and Figure 8 As shown, the fire extinguisher may also include a battery 17, a lighting port, a lighting lamp 16, a combination port, and a combination lamp 8.

Illumination lamp 16 is located inside the illumination hole, above battery 17, and is connected / electrically connected to battery 17. A combination hole is located on the side wall of housing 9, above the tool hole. Combination lamp 8 is located on the inner wall of the combination hole and connected to battery 17, used to emit floodlight or strobe. Specifically, combination lamp 8 consists of two sets of LEDs on a PCB, used for floodlight and strobe respectively; this is technology known to those skilled in the art and will not be described in detail here.

[0113] When illumination is needed, hold the housing 9, point the light 16 towards the dark area, and turn it on. When floodlighting is needed, turn on the combination light 8 to emit floodlight; similarly, when strobe is needed, turn on the combination light 8 to emit strobe. The selection and control of floodlight and strobe are techniques known to those skilled in the art, and therefore will not be described in detail.

[0114] In this embodiment of the present invention, such as Figure 1 and Figure 8 As shown, the lighting assembly may also include a push-button switch 10. Specifically, the push-button switch 10 is disposed between the combination hole and the tool hole, and is connected to the lighting lamp 16 and / or the combination lamp 8 for controlling the lighting lamp 16 and / or the combination lamp 8 to start and stop.

[0115] In this embodiment of the present invention, the housing 9 may further include a battery charging port or a battery replacement port disposed on the side wall for charging or replacing the battery.

[0116] In this embodiment of the present invention, such as Figure 1 As shown, the top of the box 9 is sloped to cooperate with the second limiting part 6 to form an overall square shape.

[0117] Through the above technical solution, the vehicle-mounted fire extinguisher provided by this utility model, which is easy to disassemble and replace, can be replaced and installed by opening the limiting component, placing the tank 1 inside the U-shape of the limiting component, and then fixing it in place. After replacement and installation, pressing activates the pressing component, causing the extinguishing medium inside the tank 1 to be sprayed out along the spray pipe 14, thereby achieving the fire extinguishing operation. The combined action of the limiting component and the pressing component enables safe and stable replacement and reliable use of the tank 1, reducing the overall replacement frequency and the number of discarded fire extinguishers, thus reducing costs. At the same time, the tank 1 is easy to replace, and the operation and maintenance efficiency is high, thereby improving the flexibility of operation, maintenance, and use.
