Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a cleaning tank with a self-extinguishing fire function. Background Technology

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

[0003] Currently, there are many types of cleaning buckets on the market. Commonly used cleaning buckets typically consist of a bucket body and a filter screen. The filter screen has several filter holes, and a baffle is installed inside the bucket at its opening. During use, the filter screen is placed inside the bucket and supported by the baffle, thus installing the filter screen within the bucket body. However, in situations involving cleaning oils, flammable chemicals, etc., there is a possibility of accidental combustion of the contents inside the bucket. To facilitate quick fire extinguishing in such cases, a lid is usually provided. In the event of an accidental fire, the user can cover the bucket opening with the lid to isolate the interior from the outside air, thereby extinguishing the fire. While this structure meets the requirements for extinguishing fires in cleaning buckets, the lid is usually detachable from the bucket body. During use, the lid is typically placed to the side, posing a risk of loss. Furthermore, in actual use, when a cleaning bucket catches fire, most users are in a state of panic and are unlikely to think of using the lid to extinguish the fire in the chaos. Furthermore, even if a user tries to extinguish a fire inside the bucket with the lid, manually closing the lid poses a safety risk due to the flames inside. Additionally, if the user is not nearby and cannot detect and extinguish the fire in time, the burning materials inside the bucket will continue to burn, drastically increasing the safety risk.

[0004] In conclusion, the existing cleaning tubs on the market currently have the defect of not being able to extinguish fires automatically, posing a significant safety risk. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, the aim is to provide a washing tub with a self-extinguishing fire function. One side of the tub lid is hinged to the outside of the tub opening. Simultaneously, an automatic lid-closing assembly is installed between the inner side of the lid and the inner side of the tub opening. When a fire occurs inside the tub, the automatic lid-closing assembly automatically closes the lid, sealing the tub opening and isolating the tub's interior from the outside air. This achieves automatic fire extinguishing and avoids safety issues caused by delayed detection, forgetting to operate, or incorrect operation when a fire occurs inside the washing tub, thus improving safety.

[0006] The specific technical solution is as follows:

[0007] A cleaning tub with a self-extinguishing fire function, comprising a tub body and a tub lid, further comprising an automatic closing assembly, wherein one side of the tub lid is hinged to the outside of the tub opening of the tub body, and the automatic closing assembly is disposed on the inside of the tub lid and the inside of the tub opening of the tub body.

[0008] Furthermore, the automatic lid-closing assembly includes an upper connecting part, a lower connecting part, a lid-closing spring, a pull cable, and a triggering component. Both the upper and lower connecting parts are installed on the inner wall of the lid, and the upper connecting part is located on the side of the lower connecting part away from the hinged part where the lid is hinged to the bucket body. One end of the triggering component is hinged to the lower connecting part, and the other end of the triggering component is connected to one end of the lid-closing spring. The other end of the lid-closing spring is connected to the upper connecting part. Furthermore, the end of the lid-closing spring connected to the triggering component is also connected to one end of the pull cable. The other end of the pull cable is connected to the inner side of the bucket opening of the bucket body. Moreover, the triggering component disconnects when the flame is burning.

[0009] The aforementioned cleaning tub with a self-extinguishing fire function includes a triggering component comprising a first connecting rod, a second connecting rod, and a heat-sensitive fracture component. One end of the first connecting rod is hinged to the lower connecting part, and a heat-sensitive fracture component is provided between the other end of the first connecting rod and one end of the second connecting rod. The other end of the second connecting rod is connected to one end of the closing spring and one end of the pull cable.

[0010] In the aforementioned cleaning tub with a self-extinguishing fire function, the component that breaks upon heating is a hot-melt wire.

[0011] The aforementioned cleaning tub with a self-extinguishing fire function also includes a connecting strip, the two ends of which are connected to the upper connecting part and the lower connecting part respectively to form an integrated structure.

[0012] The aforementioned cleaning tub with a self-extinguishing fire function further includes an adapter, which is a cylindrical structure. One end of the adapter is a hook end, and the other end is a sleeve end. The sleeve end is rod-shaped and has an end thread. The diameter of the hook end is larger than the diameter of the sleeve end. The sleeve end passes through one end of the trigger assembly, and the hook end abuts against one side of the trigger assembly. A locking nut is screwed onto the sleeve end. A hook hole is provided on the hook end. One end of the closing spring is hooked into the hook hole, and one end of the pull cable is sleeved on the sleeve end and located between the trigger assembly and the locking nut.

[0013] The aforementioned cleaning tub with a self-extinguishing fire function includes a filter screen inside the tub, the filter screen being arranged in a tub shape, and several outwardly extending retaining edges at the opening of the filter screen. At the same time, a retaining edge that mates with the retaining edges is provided on the inner wall of the tub, and a handle is provided on the filter screen.

[0014] In the aforementioned cleaning tub with a self-extinguishing fire function, the side wall of the tub body is recessed inward to form a retaining edge inside the tub, and the side wall of the tub body is recessed inward to form a handle outside the tub.

[0015] The aforementioned cleaning tub with a self-extinguishing fire function further includes an anti-reverse component. The anti-reverse component includes a locking rod, a locking block, a sleeve block, an anti-reverse spring, and an unlocking pull rope. The sleeve block is installed on the outer wall of the tub opening. One end of the sleeve block has an insertion port along the axial direction of the tub body, and the other end of the sleeve block has a sliding hole connecting to the insertion port along the tangential direction of the tub body. One end of the locking block is slidably disposed in the sliding hole, and the other end of the locking block is arranged at an angle and extends into the insertion port. The anti-reverse spring is disposed in the sliding hole, and one end abuts against the end of the locking block located in the sliding hole. One end of the unlocking pull rope is connected to the locking block abutting against the end of the anti-reverse spring, and the other end of the unlocking pull rope passes through the sliding hole and extends to the outside of the sleeve block. The locking rod is disposed on the outer edge of the tub lid, and when the tub lid is flipped onto the tub body, the locking rod corresponds to the insertion port.

[0016] The aforementioned cleaning tub with self-extinguishing fire function also includes a scald-proof handle. Both sides of the tub body are provided with sleeve blocks, and each sleeve block corresponds to a scald-proof handle. One end of the scald-proof handle is hinged to the sleeve block and located below the locking block. At the same time, there is a gap between the scald-proof handle and the locking block, and the gap is larger than the diameter of the locking rod. The hinge point of the scald-proof handle on the sleeve block is located on the side of the locking block away from the tub body. Furthermore, the end of the scald-proof handle that is hinged to the sleeve block extends into the inlet and is provided with an inclined contact surface.

[0017] The aforementioned cleaning tub with a self-extinguishing fire function is provided, wherein a thermometer and / or a pressure gauge are installed on the tub lid, the probe of the thermometer and / or pressure gauge passes through the tub lid, and when the tub lid covers the opening of the tub body, the probe extends into the inner cavity of the tub body.

[0018] The positive effects of the above technical solution are:

[0019] The aforementioned washing tub with self-extinguishing fire function utilizes an automatic lid-closing assembly. One side of the lid is hinged to the outside of the tub opening. An upper connecting part, a lower connecting part, a closing spring, a pull cable, and a triggering component are installed between the lid and the tub body. The upper and lower connecting parts are spaced apart on the inside of the lid, with the upper connecting part located away from the hinge point where the lower connecting part is hinged to the tub body. The lower connecting part is hinged to one end of the triggering component, and the upper connecting part is connected to one end of the closing spring. The other end of the triggering component is connected to the other end of the closing spring and then to one end of the pull cable. The other end of the pull cable is connected to the inside of the tub opening. This ensures that when the lid is opened, the combined force of the pull cable, closing spring, and triggering component is located at the hinge point between the lid and the tub body along the axial direction of the tub. The lid is positioned either on the same straight line or on the side away from the barrel body, so that the closing spring is rigidly connected to the trigger component and the pull cable, preventing it from retracting and maintaining the stability of the three. This allows the lid to remain open. When the trigger component burns out inside the barrel, it loses its restraint on the closing spring and pull cable. The combined force point of the closing spring and pull cable is located at the hinge between the lid and the barrel body, axially closer to the barrel body. This allows the closing spring to retract, pulling the lid to flip towards the barrel body, automatically closing the lid onto the barrel body. This automatically isolates the barrel cavity from the outside air, meeting the self-extinguishing requirements. This effectively avoids safety problems caused by users not noticing the fire in time, forgetting to operate, or operating incorrectly when the cleaning barrel catches fire, thus improving safety.

[0026] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 5 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0027] Figure 1 This is a structural diagram of an embodiment of a cleaning tub with a self-extinguishing fire function according to the present invention. Figure 2 This is a diagram showing the state of a cleaning tub with a self-extinguishing fire function when the lid is open, according to the present invention. Figure 3 This is a diagram illustrating the state of a cleaning tub with a self-extinguishing fire function during the closing process of its lid, according to the present invention. Figure 1 , Figure 2 as well as Figure 3 As shown, the cleaning tub with self-extinguishing fire function provided in this embodiment includes: tub body 1, tub lid 2, and automatic lid closing component 3 disposed between tub body 1 and tub lid 2. When the tub is burning, the automatic lid closing component 3 can automatically cover the opening of the tub body 1 with the tub lid 2, thereby isolating the inner cavity of the tub body 1 from the outside air, thus achieving the purpose of automatic fire extinguishing.

[0028] Specifically, the lid 2 is hinged to the outside of the opening of the barrel body 1 on one side, enabling the lid 2 to flip on the barrel body 1. This allows the lid 2 to be attached to the barrel body 1, avoiding the problem of it being difficult to find in critical moments. In addition, the flipping of the lid 2 can also close or open the opening of the barrel body 1. Furthermore, the automatic lid closing component 3 is set inside the lid 2 and inside the opening of the barrel body 1, so that when the lid 2 covers the opening of the barrel body 1, the automatic lid closing component 3 is completely inside the barrel cavity of the barrel body 1, without affecting the lid 2's attachment to the barrel body 1, thus ensuring reliability during fire extinguishing.

[0029] Specifically, the automatic lid-closing assembly 3, located between the bucket body 1 and the lid 2, includes an upper connecting part 31, a lower connecting part 32, a closing spring 33, a pull cable 34, and a trigger assembly 35. During installation, both the upper connecting part 31 and the lower connecting part 32 are mounted on the inner wall of the lid 2, with the upper connecting part 31 located on the side of the lower connecting part 32 away from the hinge point where the lid 2 is hinged to the bucket body 1. This creates different distances between the upper connecting part 31 and the lower connecting part 32 and the hinge point where the lid 2 is hinged to the bucket body 1, providing conditions for the subsequent trigger assembly 35, closing spring 33, and pull cable 34 to form a triangular stable state and for the lid 2 to be automatically closed by pulling it at an angle. Furthermore, one end of the trigger assembly 35 is hinged to the lower connecting part 32, and the other end of the trigger assembly 35 is connected to one end of the closing spring 33, making the extension and retraction state of the closing spring 33 related to the trigger assembly 35. In addition, the other end of the closing spring 33 is connected to the upper connecting part 31, so that the closing spring 33 can directly pull the lid 2 through the upper connecting part 31. Furthermore, the end of the closing spring 33 connected to the trigger component 35 is also connected to one end of the pull cable 34, and the other end of the pull cable 34 is connected to the inside of the opening of the bucket body 1. During normal use, the lid 2 is in the open state. At this time, the trigger component 35, the pull cable 34, and the closing spring 33 are arranged at the three corners of the triangle, so that the closing spring 33 is rigidly connected by the trigger component 35 and the pull cable 34 and cannot retract. Moreover, the point of force of the pull cable 34, the closing spring 33, and the trigger component 35 is located at the hinge part of the lid 2 and the bucket body 1, which is on the same straight line in the axial direction of the bucket body 1 or on the side away from the bucket body 1. This makes the lid 2 lack the pulling force to flip towards the bucket body 1, maintaining the stability of the three, thereby keeping the lid 2 in the open state and meeting the needs of normal use. In addition, the trigger component 35 is disconnected when the flame is burning. That is, when the cleaning tub catches fire, the flame causes the trigger component 35 to disconnect. At this time, the closing spring 33 and the pull cable 34 are no longer restricted by the trigger component 35. The point of force of the closing component and the pull cable 34 is located on the side closer to the tub body 1 in the axial direction of the hinge structure of the lid 2 and the tub body 1. This allows the closing spring 33 to pull the lid 2 towards the side of the tub body 1 by contraction, so as to automatically cover the lid 2 on the tub body 1, thereby isolating the inner cavity of the tub body 1 from the outside air and realizing the self-extinguishing of the cleaning tub. Preferably, the other end of the trigger component 35 is hinged to one end of the lid-closing spring 33. In addition, the end of the lid-closing spring 33 connected to the trigger component 35 can also be hinged to one end of the pull cable 34, so that the three can rotate relative to each other. Thus, before and after the trigger component 35 breaks, the angles of the lid-closing spring 33 and the pull cable 34 relative to the trigger component 35 can change, providing a condition for the lid-closing spring 33 to be aligned with the pull cable 34 and directly pull the lid 2 to close.

[0030] More specifically, the trigger assembly 35 includes a first connecting rod 351, a second connecting rod 352, and a heat-induced fracture element 353. During installation, one end of the first connecting rod 351 is hinged to the lower connecting part 32, and a heat-induced fracture element 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-induced fracture element 353, and after the heat-induced fracture element 353 breaks due to heat, the first connecting rod 351 and the second connecting rod 352 can be disconnected from each other, thereby meeting the usage requirements of the trigger assembly 35 for heat-induced fracture. It is worth noting that the other end of the second link 352 is connected to one end of the closing spring 33 and one end of the cable 34. That is, under normal temperature, the trigger assembly 35 is an integral structure that can stably hold the closing spring 33 and the cable 34. However, when the heat-induced fracture component 353 breaks due to combustion inside the cleaning tub, the first link 351 and the second link 352 disconnect, that is, the trigger assembly 35 is disconnected in the middle and loses its restriction on the closing spring 33 and the cable 34. This allows the closing spring 33 and the cable 34 to pull the lid 2 diagonally to flip it over and cover the opening of the tub 1.

[0031] More specifically, the heat-induced fracture element 353 of the trigger component 35 is a thermal fuse. When burning inside the barrel 1, the flame causes the heat-induced fracture element 353 to fracture at a preset temperature, meeting the requirements for automatic triggering. It is worth noting that there are many types of thermal fuses available on the market, and different types have different heat-induced fracture temperatures. Therefore, in this embodiment, a thermal fuse with a suitable temperature is selected and purchased based on the required temperature to meet the usage requirements. Therefore, its specific specifications and models will not be elaborated upon again.

[0032] More specifically, a connecting strip 311 is provided between the upper connecting part 31 and the lower connecting part 32, with the upper connecting part 31 and the lower connecting part 32 located at both ends of the connecting strip 311. The connecting strip 311 connects to the upper connecting part 31 and the lower connecting part 32 to form an integrated structure, improving the integrity of the upper connecting part 31 and the lower connecting part 32, facilitating disassembly and assembly, and improving the overall structural strength. Preferably, each end of the connecting strip 311 has an extension, which is bent to form the upper connecting part 31 and the lower connecting part 32. During processing, the connecting strip 311 and its extensions at both ends are first stamped, and then the extensions at both ends are bent, making processing more convenient. In addition, during installation, the upper connecting part 31 and the lower connecting part 32 can be installed on the bucket lid 2 by installing the connecting strip 311 on the inner wall of the bucket lid 2, making disassembly and assembly more convenient, and also making the relative position between the upper connecting part 31 and the lower connecting part 32 more stable, resulting in a more reasonable structural design.

[0033] More specifically, the automatic closing assembly 3 also includes a connecting part 36, through which the closing spring 33, the pull cable 34, and the trigger assembly 35 are connected. In this case, the connecting part 36 has a columnar structure, and its two ends are a hook end and a sleeve end, respectively. One end of the sleeve end is connected to the hook end, and the sleeve end has a rod-shaped structure. The end of the sleeve end facing away from the hook end has an end thread, and the end thread engages with a locking nut. At this point, the diameter of the hook end is set larger than the diameter of the sleeve end, allowing the adapter 36 to form an approximately "T"-shaped structure. During installation, the sleeve end passes through one end of the trigger component 35, and the hook end abuts against one side of the trigger component 35. The sleeve end engages with the trigger component 35, and the hook end provides end-positioning. Additionally, a locking nut is screwed onto the sleeve end, allowing the adapter 36 to be positioned on both sides of the trigger component 35 via the hook end and the locking nut, achieving a stable connection between the adapter 36 and one end of the trigger component 35. Furthermore, a hook hole is provided on the hook end, and one end of the closing spring 33 is hooked into the hook hole, enabling quick connection of the opening spring. Moreover, one end of the pull cable 34 is sleeved on the sleeve end and positioned between the trigger component 35 and the locking nut, allowing one end of the pull cable 34 to engage with the adapter 36, facilitating assembly and disassembly. Preferably, the end face of the connecting end opposite to the sleeve end is provided with one of the following: slotted hole, cross hole, and hexagonal hole, so that tools such as screwdrivers can be used to turn the adapter 36 to realize the disassembly and assembly of the end thread of the sleeve end and the locking nut, thereby facilitating the connection between the adapter 36 and one end of the trigger component 35 and making the installation more convenient.

[0034] More specifically, a filter screen 4 is also installed inside the barrel body 1. The filter screen 4 is arranged in a barrel shape, with several outwardly extending retaining edges at the opening. These retaining edges extend the outer edge of the filter screen 4. Furthermore, a retaining edge is provided on the inner wall of the barrel body 1 to cooperate with the retaining edges. When the filter screen 4 is placed inside the barrel cavity of the barrel body 1, it can overlap the retaining edges on the retaining edge on the inner wall of the barrel body 1, thus suspending the filter screen 4 within the barrel cavity of the barrel body 1 and meeting the filtration and cleaning requirements. In addition, a handle is provided on the filter screen 4, with both ends hanging on either side of the filter screen 4, allowing users to place or remove the filter screen 4 from the barrel body 1 using the handle, making it more convenient to use.

[0035] More specifically, the retaining edge on the barrel 1 is formed inside the barrel by indenting the side wall of the barrel 1, i.e., by stamping, which makes processing more convenient. Furthermore, when the retaining edge is formed by indenting the side wall of the barrel 1, a gripper 11 is simultaneously formed on the outside of the barrel 1, which facilitates the user's fingers to be inserted into the gripper 11, thereby making it easier to lift the barrel 1 and further improving ease of use.

[0036] Figure 4This is a schematic diagram of the installation of an anti-reverse component with a scald-proof handle for a cleaning tub with a self-extinguishing fire function according to the present invention. Figure 5 This is a cross-sectional view of the anti-reverse component with a scald-proof handle and a self-extinguishing fire function of a washing tub according to the present invention, in its usage state. Figure 4 and Figure 5As shown, an anti-reverse component 5 is also provided between the barrel body 1 and the barrel lid 2. When the barrel lid 2 closes the barrel opening of the barrel body 1, the inside of the barrel body 1 is still burning and will continue to burn for a period of time after the barrel lid 2 is closed. At this time, the heat released during the combustion process will cause the internal air to expand, thereby pushing the barrel lid 2 open in the reverse direction, affecting the ability of the barrel lid 2 to isolate the outside air, resulting in a longer fire extinguishing time and affecting the fire extinguishing effect. However, by setting the anti-reverse component 5 between the barrel body 1 and the barrel lid 2, the anti-reverse component 5 can prevent the barrel lid 2 from opening in the reverse direction after it is placed on the barrel body 1, thus improving the air isolation effect and achieving rapid 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 pull rope 55. During installation, the sleeve block 53 is installed on the outer wall of the barrel opening of the barrel body 1. Furthermore, an insertion port 531 is provided on one end of the sleeve block 53 along the axial direction of the barrel body 1, and a sliding hole 532 communicating with the insertion port 531 is provided on the other end of the sleeve block 53 along the tangential direction of the barrel body 1, thereby realizing the connection between the insertion port 531 and the sliding hole 532. Furthermore, one end of the locking block 52 is slidably disposed within the sliding hole 532, allowing the locking block 52 to extend and retract within the sliding hole 532. The other end of the locking block 52 is arranged at an angle and extends into the socket 531. That is, when the locking block 52 extends and retracts within the sliding hole 532, the locking block 52 can block or open the socket 531. Moreover, the angled surface of the locking block 52 is formed by chamfering the upper edge of the end of the locking block 52 extending into the socket 531, which provides a certain condition for subsequently pushing the locking block 52 through the angled surface. In addition, an anti-reverse spring 54 is disposed within the sliding hole 532, with one end abutting against the end of the locking block 52 located within the sliding hole 532. The anti-reverse spring 54 provides a preload force to the locking block 52, allowing one end of the locking block 52 to be located within the socket 531. In addition, it also provides a condition for the locking block 52 to subsequently retract into the sliding hole 532. In addition, one end of an unlocking pull rope 55 is connected to the locking block 52, which 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 by unlocking the pull rope 55, so that the locking block 52 can compress the anti-reverse spring 54 and retract into the sliding hole 532, thereby opening the socket 531.Additionally, the locking rod 51 is positioned on the outer edge of the lid 2. When the lid 2 is flipped onto the barrel body 1, the locking rod 51 aligns with the insertion port 531. That is, when the lid 2 is not closed, the locking block 52 blocks the insertion port 531 under the action of the anti-reverse spring 54. When the lid 2 is flipped onto the barrel body 1 under the action of the closing spring 33, due to the inertia and its own weight, the lid 2 will quickly flip towards the barrel body 1, thereby locking the locking rod 51 on the lid 2. The inclined surface of the locking block 52 in the socket 531 is impacted, and the inclined surface pushes the locking block 52 toward the sliding hole 532 to open the socket 531, allowing the locking rod 51 to pass over the locking block 52. 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 and preventing the lid 2 from being pushed open by the direction after it is closed. This improves the air isolation effect of the lid 2 and achieves 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, allowing the locking rod 51 to disengage from the socket 531, thus facilitating the opening of the lid 2. Preferably, an extension rod is provided between the locking rod 51 and the lid 2. The extension rod is arranged along the axial direction of the lid 2. One end of the extension rod is fixed to the outer edge of the lid 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. The extension rod creates a gap between the locking rod 51 and the lid 2, so that the sleeve block 53 can be placed on the bucket body 1 at a position lower than the bucket opening. This ensures that there is clearance space at the bucket opening of the bucket body 1, so that after the lid 2 is placed on the bucket body 1, the sleeve block 53 will not block the edge of the lid 2 from covering the bucket opening, while the locking rod 51 can extend into the insertion port 531 of the sleeve block 53. The structural design is more reasonable.

[0037] More specifically, a scalding handle 6 is also provided on the tub body 1. When the side wall of the tub body 1 becomes too hot to move due to combustion inside, the scalding handle 6 can be used to move the tub, improving safety. At this time, sleeve blocks 53 are provided on both sides of the tub body 1, and each sleeve block 53 corresponds to a scalding handle 6, allowing the tub to be lifted using both scalding handles 6. During installation, one end of the scalding handle 6 is hinged to the sleeve block 53 and positioned below the locking block 52, allowing the scalding handle 6 to rotate on the corresponding sleeve block 53. Simultaneously, a gap is provided between the scalding handle 6 and the locking block 52, and this gap is larger than the diameter of the locking rod 51, providing space for the locking rod 51 to pass over and be positioned 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 tub body 1, so that the hinge point of the anti-scalding handle 6 on the sleeve block 53 can be misaligned with the locking rod 51 that cooperates with the locking block 52. Furthermore, one end of the anti-scalding handle 6 that is hinged to the sleeve block 53 extends into the inlet 531 and is provided with an inclined contact surface 61. When the tub lid 2 is closed and the locking rod 51 impacts the inclined surface of the locking block 52, the locking rod 51 will continue to impact the contact surface 61 of the anti-scalding handle 6 after passing the locking block 52, thereby pressing down the contact surface 61 of the anti-scalding handle 6. This causes the other end of the anti-scalding handle 6 to flip upward. That is, when the tub lid 2 is not closed, the anti-scalding handle 6 is in a hanging state. When the locking rod 51 presses down on the contact surface 61 of the anti-scalding handle 6, the anti-scalding handle 6 can unfold from the corresponding sleeve block 53, thereby making it convenient for the user to hold the anti-scalding handle 6 to lift the washing tub and avoid scalding. Preferably, the bottom of the sleeve block 53, on the side opposite to the bucket body 1, has a flip groove with one side connected to the insertion port 531. The hinge part of the anti-scalding handle 6 is located in the flip groove, which not only provides clearance for the flipping of the anti-scalding handle 6, but also prevents the anti-scalding handle 6 from flipping up excessively, serving as a blocking structure when the anti-scalding handle 6 is raised, thus facilitating user operation. It is worth noting that after the locking rod 51 enters into the insertion port 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 swing on the sleeve block 53, thereby raising the other end of the anti-scalding handle 6, thus realizing the unfolding of the anti-scalding handle 6 from the sleeve block 53, allowing the user to transfer the washing bucket through the anti-scalding handle 6, improving safety.

[0038] More specifically, a thermometer and / or pressure gauge are also installed on the lid 2. At this time, the probe of the thermometer and / or pressure gauge is passed through the lid 2 and when the lid 2 covers the opening of the barrel 1, the probe is inserted into the inner cavity of the barrel 1. The changes in the state inside the barrel are observed through the thermometer and / or pressure gauge, which makes it safer to carry out subsequent processing of the cleaning barrel after the fire is extinguished.

[0039] The washing tub with self-extinguishing fire function provided in this embodiment includes a lid 2, a tub body 1, and an automatic lid-closing assembly 3. The automatic lid-closing assembly 3 includes an upper connecting part 31, a lower connecting part 32, a closing spring 33, a pull cable 34, and a triggering assembly 35. The lid 2 is hinged to the outside of the opening of the tub body 1, and the upper connecting part 31 and the lower connecting part 32 are spaced apart on the lid 2. One end of the triggering assembly 35 and one end of the closing spring 33 are respectively connected to the lower connecting part 32 and the upper connecting part 31. Simultaneously, the other end of the triggering assembly 35 and the other end of the closing spring 33 are connected to one end of the pull cable 34. One end is connected, and the other end of the pull cable 34 is connected to the inner cavity of the barrel 1. The trigger component 35 is disconnected when the flame is burning, so that when the barrel lid 2 is open, the trigger component 35 and the pull cable 34 jointly pull the lid closing spring 33, and the point of force of the three is located on the side of the hinge structure between the barrel lid 2 and the barrel 1 away from the barrel 1, so as to maintain the barrel lid 2 in the open state. When the trigger component 35 is disconnected due to the burning inside the barrel 1, the lid closing spring 33 and the pull cable 34 will pull the barrel lid 2 to tilt towards the barrel 1 to achieve automatic closing of the barrel lid 2, thereby isolating the air and achieving automatic fire extinguishing, improving the safety of use.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
