Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a cleaning bucket with a fire self-extinguishing function. Background Art

[0002] In production and life, there are many scenarios where equipment and items need to be cleaned. In order to facilitate cleaning, a cleaning bucket is usually used.

[0003] At present, there are many types of cleaning barrels on the market. The more commonly used cleaning barrels usually include a barrel body and a filter screen. The filter screen is provided with a plurality of filter holes, and a retaining edge is provided in the barrel body and at the barrel mouth. When in use, the filter screen is placed in the barrel body and supported by the retaining edge to achieve the installation of the filter screen in the barrel body. However, in cleaning occasions such as cleaning oil and flammable chemical products, there is a situation where the contents in the barrel accidentally burn. For the above-mentioned accidental burning situation, in order to facilitate the user to quickly extinguish the fire, a barrel cover is usually configured, that is, when an accidental burning occurs, the user can cover the barrel mouth of the barrel body with the barrel cover to isolate the barrel cavity from the outside air, thereby achieving the purpose of extinguishing the fire. Although the above structure can meet the use requirements of extinguishing the fire after the cleaning barrel catches fire, the barrel cover is usually a structure detached from the barrel body. When in use, the barrel cover is usually placed on the side, and there is a risk of losing the barrel cover. In addition, in actual use, when the cleaning barrel catches fire, most users will be in a state of panic, and it is not easy to think of a solution to extinguish the fire with the barrel cover in a panic. Moreover, when a fire occurs in the barrel, even if the user thinks of using the barrel cover to put out the fire, there is a certain safety risk in manually closing the barrel cover due to the influence of the flames in the barrel. In addition, when a cleaning barrel catches fire, if the user is not nearby and cannot find and put out the fire in time, the burning materials in the cleaning barrel will continue to burn, and the safety risk will increase sharply.

[0004] In summary, the existing cleaning barrels on the market currently have the defect that they cannot automatically extinguish fire after a fire occurs, and the safety risk is relatively large. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 5 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0020] Figure 1 It is a structural diagram of an embodiment of a cleaning bucket with a fire self-extinguishing function of the present invention; Figure 2 This is a state diagram of a cleaning bucket with a fire self-extinguishing function when the lid is opened; Figure 3 FIG. 1 is a state diagram of a cleaning bucket with a fire self-extinguishing function during the closing process of the bucket cover of the present invention. Figure 1 , Figure 2 as well as Figure 3 As shown, the cleaning barrel with a fire self-extinguishing function provided in this embodiment includes: a barrel body 1, a barrel cover 2, and an automatic lid closing assembly 3 arranged between the barrel body 1 and the barrel cover 2. The automatic lid closing assembly 3 can automatically cover the barrel cover 2 on the barrel mouth of the barrel body 1 when burning in the barrel, thereby isolating the barrel cavity of the barrel body 1 from the outside air, thereby achieving the purpose of automatic fire extinguishing.

[0021] Specifically, one side of the barrel cover 2 is hinged to the outside of the barrel mouth of the barrel body 1, so that the barrel cover 2 can be turned over on the barrel body 1, so that the barrel cover 2 can be connected to the barrel body 1, avoiding the problem of being difficult to find at a critical moment. In addition, the barrel mouth of the barrel body 1 can be closed or opened by turning the barrel cover 2. In addition, the automatic lid closing component 3 is arranged on the inner side of the barrel cover 2 and the inner side of the barrel mouth of the barrel body 1, so that the automatic lid closing component 3 can be completely in the barrel cavity of the barrel body 1 when the barrel cover 2 covers the barrel mouth of the barrel body 1, and will not affect the barrel cover 2 covering the barrel body 1, thereby ensuring the reliability during fire extinguishing.

[0022] Specifically, the automatic lid closing assembly 3 disposed between the barrel body 1 and the barrel cover 2 further comprises an upper connecting portion 31, a lower connecting portion 32, a lid closing spring 33, a cable 34 and a trigger assembly 35. During installation, the upper connecting portion 31 and the lower connecting portion 32 are both installed on the inner wall of the barrel cover 2, and the upper connecting portion 31 is located on the side of the lower connecting portion 32 away from the hinged portion of the barrel cover 2 hinged on the barrel body 1, so that the upper connecting portion 31 and the lower connecting portion 32 are at different distances from the hinged portion of the barrel cover 2 hinged on the barrel body 1, which provides conditions for the subsequent trigger assembly 35, the lid closing spring 33 and the cable 34 to form a triangular stable state and the subsequent inclined pull of the barrel cover 2 to realize the automatic closing of the barrel cover 2. In addition, one end of the trigger assembly 35 is hinged on the lower connecting portion 32, and the other end of the trigger assembly 35 is connected to one end of the lid closing spring 33, so that the telescopic state of the lid closing spring 33 is related to the trigger assembly 35. In addition, the other end of the lid closing spring 33 is connected to the upper connecting portion 31, that is, the lid closing spring 33 can directly pull the barrel cover 2 through the upper connecting portion 31. In addition, one end of the lid closing spring 33 connected to the trigger assembly 35 is also connected to one end of the cable 34, and the other end of the cable 34 is connected to the inner side of the barrel mouth of the barrel body 1. In normal use, the barrel cover 2 is in an open state. At this time, the trigger assembly 35, the cable 34 and the lid closing spring 33 are arranged at the three corners of the triangle, so that the lid closing spring 33 is hard-connected by the trigger assembly 35 and the cable 34 and cannot be retracted. In addition, the common force point of the cable 34, the lid closing spring 33 and the trigger assembly 35 is located at the hinged part of the barrel cover 2 and the barrel body 1, which is located on the same straight line or away from the barrel body 1 in the axial direction of the barrel body 1, so that the barrel cover 2 lacks the pulling force to flip toward one side of the barrel body 1, and the three states are maintained stable, thereby maintaining the barrel cover 2 in an open state to meet normal use requirements. In addition, the trigger assembly 35 is disconnected when the flame is burning, that is, when a fire occurs in the cleaning barrel, the burning flame causes the trigger assembly 35 to be disconnected. At this time, the lid closing spring 33 and the cable 34 lose the restriction of the trigger assembly 35, so that the common force point of the lid closing assembly and the cable 34 is located on the side of the hinged structure of the barrel cover 2 and the barrel body 1 in the axial direction close to the barrel body 1, so that the lid closing spring 33 can pull the barrel cover 2 toward the side of the barrel body 1 by contraction, thereby achieving the purpose of automatically covering the barrel cover 2 on the barrel body 1, isolating the barrel cavity of the barrel body 1 from the outside air, and realizing self-extinguishing of the cleaning barrel. Preferably, the other end of the trigger assembly 35 is hingedly connected to one end of the lid closing spring 33. In addition, the end where the lid closing spring 33 and the trigger assembly 35 are connected and one end of the cable 34 can also be hingedly connected, so that the three can rotate relative to each other, so that before and after the trigger assembly 35 breaks, the angles of the lid closing spring 33 and the cable 34 relative to the trigger assembly 35 can change, which provides conditions for the subsequent lid closing spring 33 to be in a straight line with the cable 34 to directly pull the barrel cover 2 to close.

[0023] More specifically, the trigger assembly 35 further comprises a first connecting rod 351, a second connecting rod 352 and a heat-breaking member 353. During installation, one end of the first connecting rod 351 is hinged to the lower connecting portion 32, and a heat-breaking member 353 is provided between the other end of the first connecting rod 351 and one end of the second connecting rod 352, that is, the first connecting rod 351 and the second connecting rod 352 are connected by the heat-breaking member 353, and after the heat-breaking member 353 is heat-broken, the first connecting rod 351 and the second connecting rod 352 can be disconnected from each other, thereby satisfying the use requirement of the trigger assembly 35 being heat-broken. It is worth pointing out that the other end of the second connecting rod 352 is connected to one end of the lid closing spring 33 and one end of the cable 34, that is, at normal temperature, the trigger assembly 35 is an integral structure, which can stably hold the lid closing spring 33 and the cable 34, and when the combustion in the cleaning barrel causes the heat-breaking member 353 to break, the first connecting rod 351 and the second connecting rod 352 are disconnected, that is, the trigger assembly 35 is disconnected in the middle, and the restriction on the lid closing spring 33 and the cable 34 is lost, so that the lid closing spring 33 and the cable 34 can obliquely pull the barrel cover 2 to flip over and cover the barrel mouth of the barrel body 1.

[0024] More specifically, the heat-breaking member 353 of the trigger assembly 35 is a thermal fuse, that is, when burning in the barrel 1, the burning flame causes the heat-breaking member 353 to break at a preset temperature, meeting the use requirements of automatic triggering. It is worth pointing out that there are many types of thermal fuses available on the market, and different types of thermal fuses have different heat-breaking temperatures. Therefore, in this embodiment, a thermal fuse with a suitable temperature is selected according to the required temperature and purchased and used, and it can meet the use requirements. Therefore, its specific specifications and models are not repeated again.

[0025] More specifically, a connecting strip 311 is further provided between the upper connecting portion 31 and the lower connecting portion 32, and the upper connecting portion 31 and the lower connecting portion 32 are respectively located at the two ends of the connecting strip 311, and the connecting strip 311 is connected with the upper connecting portion 31 and the lower connecting portion 32 to form an integrated structure, which improves the integrity of the upper connecting portion 31 and the lower connecting portion 32, facilitates disassembly and assembly, and improves the overall structural strength. Preferably, an extension portion is provided at each end of the connecting strip 311, and the upper connecting portion 31 and the lower connecting portion 32 are formed after the extension portion is bent. During processing, the connecting strip 311 and the extension portions at both ends thereof are firstly punched to obtain the connecting strip 311 and the extension portions at both ends thereof, and then the extension portions at both ends are bent, which makes processing more convenient. In addition, during installation, the upper connecting portion 31 and the lower connecting portion 32 can be installed on the barrel cover 2 by installing the connecting strip 311 on the inner wall of the barrel cover 2, which makes disassembly and assembly more convenient, and can also make the relative position between the upper connecting portion 31 and the lower connecting portion 32 more stable, and the structural design is more reasonable.

[0026] More specifically, the automatic lid closing assembly 3 further includes an adapter 36, through which the lid closing spring 33, the cable 34 and the trigger assembly 35 are connected. At this time, the adapter 36 is a columnar structure, and the two ends of the adapter 36 are a hanging end and a sleeve end, one end of the sleeve end is connected to the hanging end, and the sleeve end is a rod-shaped structure, and the end of the sleeve end away from the hanging end has an end thread, and the end thread cooperates with a locking nut. At this time, the diameter of the hanging end is set to be larger than the diameter of the sleeve end, so that the adapter 36 can form an approximately "T"-shaped structure. During installation, the sleeve end is passed through one end of the trigger assembly 35 and the hanging end is against one side of the trigger assembly 35, and the sleeve end cooperates with the trigger assembly 35, and the end is limited by the hanging end. In addition, the sleeve end is screwed with a locking nut, so that the adapter 36 can be limited on both sides of the trigger assembly 35 through the hanging end and the locking nut, so as to achieve a stable connection between the adapter 36 and one end of the trigger assembly 35. In addition, a hanging hole is opened on the hanging end, and one end of the cover closing spring 33 is hung in the hanging hole, that is, the quick connection of the cover opening spring is achieved through the hanging hole on the hanging end. In addition, one end of the cable 34 is sleeved on the sleeve end and located between the trigger assembly 35 and the locking nut, so that one end of the cable 34 is sleeved with the adapter 36, which is also convenient for disassembly and assembly. Preferably, a slotted hole, a cross hole, or a hexagonal hole is provided on the end surface of the hanging end facing away from the sleeve end, so that tools such as a screwdriver can be used to twist the adapter 36 to realize the disassembly and assembly of the end thread and the locking nut of the sleeve end, thereby facilitating the connection between the adapter 36 and one end of the trigger assembly 35, making installation more convenient.

[0027] More specifically, a filter screen 4 is also provided in the barrel body 1. At this time, the filter screen 4 is arranged in a barrel shape, and a plurality of outwardly extending card edges are provided at the barrel mouth of the filter screen 4. The card edges realize the expansion of the outer edge of the filter screen 4, and a retaining edge matched with the card edge is provided on the inner wall of the barrel body 1, so that when the filter screen 4 is placed in the barrel inner cavity of the barrel body 1, the filter screen 4 can overlap the retaining edge on the inner wall of the barrel body 1 through the card edge thereon, thereby realizing the suspension of the filter screen 4 in the barrel inner cavity of the barrel body 1, meeting the filtering and cleaning requirements. In addition, a handle is provided on the filter screen 4, and the two ends of the handle are respectively hung on both sides of the filter screen 4, so that the user can place the filter screen 4 in the barrel body 1 or take it out of the barrel body 1 through the handle, which is more convenient to use.

[0028] More specifically, the retaining edge on the barrel body 1 is formed in the barrel after the side wall of the barrel body 1 is recessed inwards, that is, it is formed by stamping, which is more convenient to process. In addition, when the side wall of the barrel body 1 is recessed inwards to form the retaining edge, a grip portion 11 is simultaneously formed on the outer side of the barrel body 1, which makes it convenient for the user to insert his fingers into the grip portion 11, thereby facilitating the lifting of the barrel body 1, further improving the convenience of use.

[0029] Figure 4It is a schematic diagram of the installation of an anti-reversal assembly with an anti-scalding handle of a cleaning bucket with a fire self-extinguishing function according to the present invention; Figure 5 This is a cross-sectional view of the use state of the anti-reversal component of the cleaning bucket with a fire self-extinguishing function of the present invention with an anti-scalding handle. Figure 4 and Figure 5As shown, an anti-reversal component 5 is further provided between the barrel body 1 and the barrel cover 2. When the barrel cover 2 closes the barrel mouth of the barrel body 1, the barrel body 1 is still burning and will continue to burn for a period of time after the barrel cover 2 is closed. At this time, the heat released during the combustion process will cause the internal air to expand, thereby pushing open the barrel cover 2 in the reverse direction, affecting the ability of the barrel cover 2 to isolate the outside air, resulting in a longer fire extinguishing time and affecting the fire extinguishing effect. By providing the anti-reversal component 5 between the barrel body 1 and the barrel cover 2, the anti-reversal component 5 can reversely bounce back after the barrel cover 2 is covered on the barrel body 1, resulting in poor air isolation effect, thereby improving the air isolation effect and achieving fast and reliable fire extinguishing. At this time, the anti-reverse component 5 includes a locking rod 51, a locking block 52, a sleeve block 53, an anti-reverse spring 54 and an unlocking rope 55. During installation, the sleeve block 53 is installed on the outer wall of the barrel mouth of the barrel body 1, and a socket 531 is opened on one end of the sleeve block 53 along the axial direction of the barrel body 1, and a sliding hole 532 connecting the socket 531 is opened on the other end of the sleeve block 53 along the tangential direction of the barrel body 1, thereby realizing the penetration of the socket 531 and the sliding hole 532. In addition, one end of the locking block 52 is slidably arranged in the sliding hole 532, so that the locking block 52 can be telescopically moved in the sliding hole 532, and the other end of the locking block 52 is arranged in an inclined surface and extends into the socket 531, that is, when the locking block 52 is telescopically moved in the sliding hole 532, the locking block 52 can block the socket 531 or open the socket 531, and the inclined surface of the locking block 52 is formed by chamfering the upper edge of one end of the locking block 52 extending into the socket 531, which provides a condition for pushing the locking block 52 through the inclined surface later. In addition, the anti-reverse spring 54 is arranged in the sliding hole 532 and one end of the anti-reverse spring 54 abuts against one end of the locking block 52 located in the sliding hole 532, and the anti-reverse spring 54 provides a pre-tightening force for the locking block 52, so that one end of the locking block 52 can be in the socket 531, and in addition, it also provides a condition for the locking block 52 to be able to retract into the sliding hole 532 later. In addition, one end of an unlocking pull rope 55 is connected to the locking block 52 and abuts against one end of the anti-reverse spring 54. At the same time, the other end of the unlocking pull rope 55 passes through the sliding hole 532 and extends to the outside of the sleeve block 53, so that the user can pull the locking block 52 in the opposite direction through the unlocking pull rope 55, so that the locking block 52 can compress the anti-reverse spring 54 and then retract into the sliding hole 532, thereby opening the socket 531.In addition, the locking rod 51 is arranged on the edge of the outer side of the barrel cover 2, and when the barrel cover 2 is turned over and covered on the barrel body 1, the locking rod 51 corresponds to the socket 531, that is, when the barrel cover 2 does not close the barrel body 1, the locking block 52 blocks the socket 531 under the action of the anti-reverse spring 54, and when the barrel cover 2 is turned over under the action of the cover closing spring 33 and covers the barrel mouth of the barrel body 1, due to the inertia of the barrel cover 2 when turning over and the influence of its own gravity, it will quickly turn toward the side of the barrel body 1, so that the locking rod 51 on the barrel cover 2 1 impacts the inclined surface of the locking block 52 in the socket 531, and pushes the locking block 52 to retract into the sliding hole 532 through the inclined surface to open the socket 531, so that the locking rod 51 can pass over the locking block 52, and after the locking rod 51 passes over the locking block 52, the locking block 52 automatically returns to the socket 531 under the action of the anti-reverse spring 54, thereby blocking the locking rod 51 to prevent the barrel cover 2 from being pushed open in the opposite direction after closing, thereby improving the air isolation effect of the barrel cover 2 and realizing rapid and reliable fire extinguishing. Conversely, the locking block 52 can be pulled back into the sliding hole 532 by the unlocking rope 55 to open the socket 531, so that the locking rod 51 can be disengaged from the socket 531, thereby facilitating the opening of the barrel cover 2. Preferably, an extension rod is provided between the locking rod 51 and the barrel cover 2, and the extension rod is arranged along the axial direction of the barrel cover 2, one end of the extension rod is fixed to the outer edge of the barrel cover 2, and the other end of the extension rod is connected to one end of the locking rod 51. Preferably, the locking rod 51 and the corresponding extension rod are arranged in an "L" shape, and a gap is provided between the locking rod 51 and the barrel cover 2 through the extension rod, so that the sleeve block 53 can be arranged at a position on the barrel body 1 below the barrel mouth, ensuring that there is an avoidance space at the barrel mouth of the barrel body 1, so that after the barrel cover 2 is covered on the barrel body 1, the sleeve block 53 will not block the edge of the barrel cover 2 from covering the barrel mouth, and the locking rod 51 can extend into the socket 531 of the sleeve block 53, and the structural design is more reasonable.

[0030] More specifically, an anti-scalding handle 6 is also provided on the barrel body 1. When the temperature of the side wall of the barrel body 1 rises due to burning inside the barrel body 1 and the cleaning barrel cannot be moved by the gripping portion 11, the cleaning barrel can be moved by the anti-scalding handle 6, thereby improving the safety of use. At this time, sleeve blocks 53 are provided on both sides of the barrel body 1, and each sleeve block 53 corresponds to an anti-scalding handle 6, so that both sides of the barrel body 1 have anti-scalding handles 6, so that the cleaning barrel can be lifted by two anti-scalding handles 6. During installation, one end of the anti-scalding handle 6 is hinged on the sleeve block 53 and located below the locking block 52, so that the anti-scalding handle 6 can be turned over on the corresponding sleeve block 53. At the same time, a gap is provided between the anti-scalding handle 6 and the locking block 52, and the gap is larger than the diameter of the locking rod 51, so that a storage space is provided for the locking rod 51 to pass over the locking block 52 and be located below the locking block 52. In addition, the hinge point of the anti-scalding handle 6 on the sleeve block 53 is located on the side of the locking block 52 away from the barrel body 1, so that the hinge point of the anti-scalding handle 6 on the sleeve block 53 can be in a misaligned state with the locking rod 51 that cooperates with the locking block 52, and the end of the anti-scalding handle 6 hinged on the sleeve block 53 extends into the socket 531 and is provided with an inclined contact surface 61, so that when the barrel cover 2 is closed and the locking rod 51 impacts the inclined surface of the locking block 52, when the locking rod 51 passes over the locking block 52, it will continue to impact the contact surface 61 of the anti-scalding handle 6, thereby pressing down the contact surface 61 of the anti-scalding handle 6, so that the other end of the anti-scalding handle 6 flips upward, that is, when the barrel cover 2 is not closed, the anti-scalding handle 6 is in a vertical state, and when the locking rod 51 presses down the contact surface 61 of the anti-scalding handle 6, the anti-scalding handle 6 can be unfolded from the corresponding sleeve block 53, so that it is convenient for the user to hold the anti-scalding handle 6 to lift the cleaning barrel to avoid scalding problems. Preferably, a flip groove connected to the socket 531 is provided at the bottom of the sleeve block 53 and on the side facing away from the barrel body 1, and the hinged portion of the anti-scalding handle 6 is located in the flip groove, which can not only provide an escape space for the flipping of the anti-scalding handle 6, but also prevent the anti-scalding handle 6 from flipping up excessively, serving as a blocking structure when the anti-scalding handle 6 is lifted, thereby facilitating the user's operation. It is worth pointing out that after the locking rod 51 enters the socket 531 and passes over the locking block 52, the locking rod 51 presses down on the contact surface 61 of the anti-scalding handle 6, causing the anti-scalding handle 6 to deflect on the sleeve block 53, thereby causing the other end of the anti-scalding handle 6 to lift up, thereby realizing the deployment of the anti-scalding handle 6 from the sleeve block 53, allowing the user to transfer the cleaning barrel through the anti-scalding handle 6, which is safer. More specifically, a temperature gauge and / or a pressure gauge is also installed on the barrel cover 2. At this time, the detection head of the temperature gauge and / or the pressure gauge is passed through the barrel cover 2, and when the barrel cover 2 covers the barrel mouth of the barrel body 1, the detection head is extended into the barrel cavity of the barrel body 1. The state changes in the barrel are observed through the temperature gauge and / or the pressure gauge, so that subsequent processing of the cleaning barrel after extinguishing the fire can be safer.

[0031] The cleaning bucket with fire self-extinguishing function provided in this embodiment includes a bucket cover 2, a bucket body 1 and an automatic lid closing assembly 3, and the automatic lid closing assembly 3 includes an upper connecting part 31, a lower connecting part 32, a lid closing spring 33, a cable 34 and a trigger assembly 35; one side of the bucket cover 2 is hinged to the outer side of the bucket mouth of the bucket body 1, and the upper connecting part 31 and the lower connecting part 32 are arranged on the bucket cover 2 at intervals, and one end of the trigger assembly 35 and the lid closing spring 33 are respectively connected to the lower connecting part 32 and the upper connecting part 31, and at the same time, the other end of the trigger assembly 35 is connected to the other end of the lid closing spring 33 and then connected to one end of the cable 34. The trigger assembly 35 is connected to one end, and the other end of the cable 34 is connected to the inner cavity of the barrel body 1, and the trigger assembly 35 is disconnected when the flame is burning, so that when the barrel cover 2 is opened, the trigger assembly 35 and the cable 34 jointly pull the lid closing spring 33, and the common force point of the three is located on the side of the hinge structure of the barrel cover 2 and the barrel body 1 away from the barrel body 1, so that the barrel cover 2 can be maintained in an open state. After the trigger assembly 35 is disconnected due to combustion in the barrel body 1, the lid closing spring 33 and the cable 34 will pull the barrel cover 2 to swing toward one side of the barrel body 1 to automatically close the barrel cover 2, thereby isolating the air and realizing automatic fire extinguishing, thereby improving safety in use.
