[0034] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0035] The present application provides a portable cleaning device with an automatic tube reel function (hereinafter referred to as the cleaning device), which can be used in various life scenarios and industrial scenarios. The portable cleaning device is so-called portable in that the cleaning device can be conveniently carried to different places for use, such as being carried outdoors for use as a cleaning tool.

[0036] Please refer to Figure 1-3 In some embodiments, the cleaning device 1 includes a shell (such as 11 , 12 , 13 , 14 ), a water pump 20 , a control circuit board 30 , a hose reel device 40 , and a flushing pipeline 50 .

[0037] Please refer to Figure 2 The housing has a water storage chamber 101, an electrical component installation chamber 102 and a pipeline storage chamber 103. The housing serves as a supporting structure for the entire device, and is usually composed of a plurality of sub-housings assembled together. These sub-housings can be made of the same or different materials according to their functions. Of course, if the manufacturing technology can be realized, such as by using 3D printing technology, the housing can also be formed in one piece.

[0038] The electrical component installation cavity 102 is sealed and separated from the water storage cavity 101 and the pipeline storage cavity 103, that is, after the entire cleaning device 1 is assembled, liquid cannot flow from the water storage cavity 101 and the pipeline storage cavity 103 into the electrical component installation cavity 102, ensuring that the electrical component installation cavity 102 is always in a sealed and isolated state from the outside world. The control circuit board 30 and the water pump 20 are arranged in the electrical component installation cavity 102 to prevent the control circuit board 30 and the water pump 20 from being soaked in liquid and damaged. Of course, in other embodiments, when the cleaning device 1 is not used in a scenario where it is thrown directly into water, the electrical component installation cavity 102 can also be separated from the water storage cavity 101 and the pipeline storage cavity 103 in a non-sealed manner or only a simple waterproof seal can be performed.

[0039] In this embodiment, since the electrical component installation cavity 102 is sealed and separated from the water storage cavity 101 and the pipe storage cavity 103, protection is provided for electrical components such as the control circuit board 30 and the water pump 20. Therefore, the entire cleaning device 1 can be directly thrown into a water source (such as river water or lake water) to fill with water, that is, the entire cleaning device 1 can be used as a bucket to facilitate filling water into the water storage cavity 101.

[0040] Please refer to Figure 1-3 In some embodiments, the cleaning device 1 may further include a cover 60, which covers the liquid inlet of the water storage chamber 101 to prevent liquid from spilling out of the water storage chamber 101. In addition, in some embodiments, a handle 70 may be provided on the housing to facilitate the user to move the cleaning device 1.

[0041] For further information, please refer to Figure 2 and 3 In some embodiments, the water pump 20 is used as a driving component for driving the flow of liquid in the cleaning device 1, and various water pumps 20 applied to liquid fluids, such as high-pressure water pumps, etc., can be used. The water storage chamber 101 has a drainage hole 1011, and the water pump 20 is sealed and connected to the drainage hole 1011. The control circuit board 30 is the main control unit of the cleaning device 1, and it can adopt a main control board or other existing electrical structures that can be used for control. The control circuit board 30 is electrically connected to the water pump 20 to control the operation of the water pump 20, such as controlling the opening and closing of the water pump 20, or in some embodiments, the control circuit board 30 can also be used to adjust the power of the water pump 20, etc.

[0042] In addition, in some embodiments, other electronic components may be provided on the cleaning device 1, such as physical buttons, touch buttons, display screens, touch screens, communication units, etc., and these electronic components may be controlled by the control circuit board 30. The user may send instructions or perform human-computer interaction with the control circuit board 30 through physical buttons, touch buttons, touch screens, or external terminals (such as mobile phones, tablets, etc.) in a wired or wireless communication manner to control the cleaning device 1, such as controlling the operation of the water pump 20.

[0043] In some embodiments, the water pump 20 can be powered by an external power cord. Of course, in some embodiments, the cleaning device 1 can also have a power supply battery, which is arranged in the electrical component installation cavity 102 to prevent liquid from damaging the power supply battery during use. The power supply battery can ensure that the cleaning device 1 can be used normally in places without an external power supply. Of course, in order to further protect the power supply battery and the control circuit board 30, please refer to Figure 3 In some embodiments, the power supply battery and the control circuit board 30 can be integrated into an integral module, and the power supply battery and the control circuit board 30 can be protected by a module housing.

[0044] For further information, please refer to Figure 2 and 3 In some embodiments, the tube reel device 40 is disposed in the pipeline storage chamber 103, and is used to store the flushing pipeline 50. The flushing pipeline 50 is used for the user to guide the liquid discharged by the water pump 20 to the outside of the device and clean the cleaning object. The flushing pipeline 50 includes a tube body 51 and an external joint 52 for an external functional head, and the tube body 51 is installed on the tube reel device 40. One end of the tube body 51 is directly or indirectly sealed and connected to the output end of the water pump 20, and the other end of the tube body 51 is sealed and connected to the external joint 52. Through the tube reel device 40, when the flushing pipeline 50 is not in use, the tube body 51 can be stored in the pipeline storage chamber 103, thereby facilitating the carrying and storage of the equipment. At the same time, when it is needed, the flushing pipeline 50 can be pulled out of the pipeline storage chamber 103.

[0045] In the above embodiment, the cleaning device 1 does not need to be connected to a water pipe. In addition, the cleaning device 1 has a built-in flushing pipeline 50, which can be stored in the pipeline storage chamber 103 and can be pulled out from the pipeline storage chamber 103 for use. The entire cleaning device 1 is very convenient to carry and use. In addition, the external connector 52 can be directly used as a flushing head, and can also be connected to other external functional heads, etc., which can expand the function of the flushing pipeline 50.

[0046] Furthermore, the housing can be formed into a water storage cavity 101, an electrical component installation cavity 102 and a pipeline storage cavity 103 through various structures. In addition to these, in some embodiments, the housing can also have other cavities to achieve other corresponding functions.

[0047] Please refer to Figure 1 and 2In some embodiments, the housing includes a side housing 11, a first separator 12, a second separator 13, and a bottom housing 14. The first separator 12 is disposed in the side housing 11, and together with the side housing 11, forms a water storage chamber 101. The second separator 13 is disposed in the side housing 11 and is located below the first separator 12, and together with the side housing 11 and the first separator 12, forms an electrical component installation chamber 102. The bottom housing 14 is located at the bottom of the side housing 11, and together with the side housing 11 and the second separator 13, forms a pipeline storage chamber 103.

[0048] The side housing 11, the first separator 12, the second separator 13 and the bottom housing 14 are only divided in terms of position, and the side housing 11, the first separator 12, the second separator 13 and the bottom housing 14 are not limited to being independent parts. In some embodiments, the side housing 11, the first separator 12, the second separator 13 and the bottom housing 14 may all be integrally formed (such as 3D printing), or two or more of them may be integrally formed parts.

[0049] In addition, Figure 1 and 2 In the structure shown, the housing can be formed into a water storage chamber 101, an electrical component installation chamber 102 and a pipeline storage chamber 103 through various structures. Figure 2 In the structure shown, the water storage chamber 101, the electrical component installation chamber 102 and the pipeline storage chamber 103 are arranged in sequence from top to bottom. In other embodiments, the water storage chamber 101, the electrical component installation chamber 102 and the pipeline storage chamber 103 may also be arranged in other ways, for example, the electrical component installation chamber 102 may also be arranged side by side with the water storage chamber 101, or the electrical component installation chamber 102 may be located below or above the side of the water storage chamber 101, or the water storage chamber 101 may also be arranged around the electrical component installation chamber 102, etc.

[0050] For further information, please refer to Figure 1 and 2 In some embodiments, the side housing 11 includes a first side housing 111, a second side housing 112 and a connecting housing 113. The first side housing 111, the connecting housing 113 and the second side housing 112 are sealed and connected in sequence to form a side housing 11 that is sealed at the peripheral side.

[0051] Please refer to Figure 1 and 2 In some embodiments, the second side shell 112 protrudes toward the periphery of the shell relative to the first side shell 111 to form a step-like structure. In some embodiments, at least a portion of the first side shell 111 is a folding structure 111 that can be folded and opened in a vertical direction. Figure 1 and 2In the embodiment shown, in at least one open state of the folding structure 111, for example, when the folding structure 111 is opened upward to the maximum size, the first side shell 111 and the second side shell 112 are separated from each other; Figure 4 In the illustrated embodiment, in a folded state of the folding structure 111, for example, when folded downward to the minimum size, the first side shell 111 is folded to engage with the second side shell 112, so that the first side shell 111 and the second side shell 112 form a closed peripheral wall. In the above embodiment, the peripheral side size of the portion where the second side shell 112 is located is larger than the peripheral side size of the portion where the first side shell 111 is located, so that when the folding structure 111 is in the open state, the center of gravity of the entire device is more stable and not easy to tip over. When the folding structure 111 is in the folded state, the first side shell 111 is engaged with the second side shell 112 to form a closed peripheral wall, and no raised step structure is formed on the peripheral wall, which makes it easier to store and place, and can also prevent the raised step structure from causing damage to users or others.

[0052] For further information, please refer to Figure 1 , 2 and 4. In one embodiment, the top of the first side shell 111 has a downwardly disposed inverted body 1114, and in at least one opened state of the folding structure 111, the inverted body 1114 and the second side shell 112 are separated from each other; in a folded state of the folding structure 111, the inverted body 1114 is engaged with the second side shell 112 so that the inverted body 1114 can form a closed outer peripheral wall with the second side shell 112.

[0053] Of course, in other embodiments, the side housing 11 may also be designed to be Figure 1 , 2 The shapes other than those shown in 4 may be designed as a straight cylinder or a tapered cylinder with a larger top and a smaller bottom.

[0054] For further information, please refer to Figure 2 In some embodiments, the folding structure 111 includes a plurality of hard units 1112 and soft units 1113, wherein the hard units 1112 and soft units 1113 can be cylindrical and are sequentially staggered and connected in a vertical direction. The soft units 1113 have certain elasticity or flexibility due to material properties, so that the plurality of hard units 1112 can be folded together. Figure 4As shown. The hard unit 1112 can be made of hard plastic or other hard materials, and the soft unit 1113 can be made of rubber or other soft materials. The structure in which the hard unit 1112 and the soft unit 1113 are alternately connected can ensure that the folding structure 111 has a certain stability in the open state to avoid deformation of the first side shell 111 in the open state, and at the same time ensure that the folding structure 111 is easily folded. Of course, in other embodiments, the folding structure 111 can also be implemented with other structures, and is not limited to the structure of the hard unit 1112 and the soft unit 1113.

[0055] For further information, please refer to Figure 2 In some embodiments, the first separator 12 is disposed in the first side shell 111 and forms a water storage chamber 101 with the first side shell 111. Preferably, the first separator 12 is connected to the area outside the folding structure 111 on the first side shell 111 to prevent the folding structure 111 from affecting the first separator 12.

[0056] The second separator 13 is disposed in the first side housing 111 and below the first separator 12, and forms an electrical component installation cavity 102 with the first side housing 111 and the first separator 12. The bottom housing 14 is located at the bottom of the second side housing 112, and forms a pipeline storage cavity 103 with the second side housing 112 and the second separator 13.

[0057] Of course, in other embodiments, the first side housing 111 may not have the folding structure 111 , that is, the first side housing 111 or the side housing 11 cannot be folded and stored.

[0058] For further information, please refer to Figure 1 and 4 In some embodiments, the outer wall of the shell has a concave external connector accommodating cavity 104, and the external connector 52 can be detachably received in the external connector accommodating cavity 104.

[0059] The external connector 52 can be received in the external connector accommodating cavity 104 by, but not limited to, tight fit fixation, magnetic fixation, snap-fit ​​fixation, and repeatable adhesive fixation (such as Velcro fixation). Figure 4 In the illustrated embodiment, the size of the external connector accommodating cavity 104 matches the external connector 52, so that the external connector 52 can be inserted into the external connector accommodating cavity 104 in a tight fit manner to complete the storage of the external connector 52, making it convenient to carry and store, and also making it convenient for the user to take out the external connector 52.

When the tube body 51 is pulled out, the tube reel 41 drives the tube reel elastic member 42 to deform, and the tube reel elastic member 42 is used to provide a restoring force to automatically wind the tube body 51 onto the tube reel 41.

[0070] In some embodiments, the reel elastic member 42 is a constant force coil spring, which can ensure that the elastic restoring force formed by the reel elastic member 42 remains basically consistent when the user pulls out the tube body 51, thereby preventing the resistance from increasing when the tube body 51 is pulled out for a long length. Of course, in other embodiments, the reel elastic member 42 can also be a non-constant force ordinary coil spring or other forms of reel elastic member 42.

[0071] Please refer to Figure 6 and 7 In some embodiments, the top wall of the hose reel 41 has a protruding connection portion 413, which is fixedly connected to the free end of the constant force coil spring. When the hose reel 41 is rotated by an external force, the constant force coil spring is deformed. When the external force disappears, the constant force coil spring can pull the hose reel 41 to return to its original position.

[0072] Please refer to Figure 2 In some embodiments, the transfer channel 401 is disposed on the hose reel 41 , and the second adapter 94 is sealedly connected to the hose reel 41 and is sealedly connected to the transfer channel 401 .

[0073] Please refer to Figure 2 and 3 In some embodiments, the transfer channel 401 includes a vertical section 402 and a horizontal section 403. The vertical section 402 is sealed and plugged with the output end of the second transfer joint 94, such as the output end of the second transfer joint 94 is inserted into the vertical section 402. The output end of the second transfer joint 94 and the vertical section 402 can be rotatably and sealedly docked, so that the hose reel 41 can rotate relative to the second transfer joint 94. Of course, when the second transfer joint 94 is rotatably connected to the third transfer joint 93, the second transfer joint 94 can also be fixedly connected to the hose reel 41. The horizontal section 403 is used to seal and dock with the tube body 51 to achieve a sealed connection between the transfer channel 401 and the tube body 51.

[0074] In some embodiments, the transfer channel 401 is formed in a 90° shape in the hose reel 41 to form a vertical section 402 and a horizontal section 403. Of course, in other embodiments, the transfer channel 401 may also be in other shapes, such as a I-shape, a C-shape, or an S-shape.

[0075] For further information, please refer to Figure 2 , 6 and 7. In some embodiments, in order to enable the pipe reel 41 to be rotatably mounted on the shell, the pipe reel device further includes a pipe reel mounting seat 43. The pipe reel mounting seat 43 is disposed in the pipeline storage cavity 103 and is fixedly mounted on the shell, for example, it can be fixed on the second partition 13 or the connecting shell 113. The pipe reel 41 is rotatably mounted on the pipe reel mounting seat 43, and the pipe reel elastic member 42 is fixed on the pipe reel mounting seat 43. Compared with directly rotatably mounting the pipe reel 41 on the shell, the structure of the shell can be simplified and the manufacturing difficulty can be reduced by switching the pipe reel mounting seat 43. Moreover, through the pipe reel mounting seat 43, the pipe reel device can be formed into a modular structure. After the pipe reel 41, the pipe reel elastic member 42 and the pipe reel mounting seat 43 are assembled, the pipe reel device can be fixed to the shell as a whole. For example, Figure 2 In the embodiment, the pipe reel device is fixed upwardly to the upper wall of the pipe receiving chamber 103 (which may be the second partition 13 or the bottom wall of the connecting shell 113) through the pipe reel mounting seat 43.

[0076] For further information, please refer to Figure 6 In some embodiments, the hose reel mounting seat 43 has a top portion 431 and a side portion 432 extending downward from the top portion 431. The hose reel 41 is rotatably mounted on the top portion 431 of the hose reel mounting seat 43, and the hose reel elastic member 42 is fixed to the bottom wall of the top portion 431 of the hose reel mounting seat 43. Figure 2 and 6 The hose reel 41 has an annular tube receiving groove 414, and the tube receiving groove 414 has an opening on its circumference. The hose reel mounting seat 43 is inverted on the hose reel 41, so that the hose reel 41 is at least partially accommodated in the area formed by the top 431 and the side 432 of the hose reel mounting seat 43. Figure 2 As shown, the side portion 432 of the hose reel mounting seat 43 is located on the side of the opening to prevent the hose body 51 from falling from the opening.

[0077] Please refer to Figure 6 and 7 In some embodiments, the hose reel mounting seat 43 is an n-shaped structure, which is inverted above the hose reel 41. This structure can simplify the structure of the hose reel mounting seat 43 while preventing the tube body 51 from falling from the opening. The side portion 432 of the hose reel mounting seat 43 forms an arc space for the hose reel 41 to rotate, so that the hose reel 41 can rotate freely on the hose reel mounting seat 43. In other embodiments, the hose reel mounting seat 43 can also be designed as an inverted cup-shaped, claw-shaped structure or other structures that can play a similar function.

[0078] Please refer to Figure 2 and 7In some embodiments, the hose reel 41 includes an upper disc body 415, a lower disc body 416, and a connecting body 417 located between the upper disc body 415 and the lower disc body 416. The upper disc body 415 and the lower disc body 416 are arranged opposite to each other, and the connecting body 417 is located in the middle of the upper disc body 415 and the lower disc body 416. The upper disc body 415, the lower disc body 416, and the connecting body 417 form an annular tube receiving groove 414. The switching channel 401 extends downward from the upper end of the connecting body 417 to the side of the connecting body 417, and the tube 51 is connected to the switching channel 401 from the side of the connecting body 417, and then wound around the side of the connecting body 417.

[0079] For further information, please refer to Figure 2 as well as Figure 6 , 7 In some embodiments, the hose reel mounting seat 43 has a hose reel mounting hole 433, and the second adapter 94 is fixedly mounted in the hose reel mounting hole 433. The second adapter 94 can form an integral module with the hose reel device, that is, the hose reel device includes the second adapter 94. Of course, in some embodiments, the hose reel device may not include the second adapter 94.

[0080] Specifically, the reference Figure 6 , 7 In some embodiments, the hose reel mounting hole 433 has a first upper limit portion 434 and a first lower limit portion 435, and the second adapter 94 has a first upper limit fitting portion 942 and a first lower limit fitting portion 943. The first upper limit fitting portion 942 abuts against the first upper limit portion 434 upward to limit the second adapter 94 in the upward direction. The first lower limit fitting portion 943 abuts against the first lower limit portion 435 downward to limit the second adapter 94 in the downward direction, thereby completing the vertical limit of the second adapter 94.

[0081] For further information, please refer to Figure 6 , 7 In some embodiments, in order to simplify the structure, the first upper limit portion 434 may further include a rotation limit portion 436, and the first upper limit matching portion 942 is provided with a rotation limit matching portion 942. When the first upper limit matching portion 942 abuts against the first upper limit portion 434 upward, the rotation limit matching portion 942 is engaged with the rotation limit portion 436, thereby realizing the rotation limit of the second adapter, so that it cannot rotate relative to the hose reel mounting seat 43.

[0082] More specifically, please refer to Figure 6 , 7In some embodiments, the rotation limiting portion 436 is a protruding bump, and the rotation limiting matching portion 942 is a groove. The rotation limiting portion 436 protrudes downward on the first upper limit portion 434 to be inserted downward into the rotation limiting matching portion 942 of the first upper limit matching portion 942.

[0083] Please refer to Figure 6 , 7 In some embodiments, the first upper limit portion 434 and the first lower limit portion 435 are distributed at different heights in the hose reel mounting hole 433. The first upper limit portion 434 and the first lower limit portion 435 can be multiple, respectively, and they are arranged along the circumference of the hose reel mounting hole 433. The first upper limit matching portion 942 can also be multiple, and form a convex structure to be arranged opposite to the first upper limit portion 434. The first lower limit matching portion 943 is a convex ridge arranged around the central axis of the second adapter 94 so as to be able to abut against the first lower limit portion 435. Of course, the first upper limit matching portion 942 can also be designed as an annular convex ridge, and the first lower limit matching portion 943 can also be designed as a convex structure.

[0084] The first lower limit portion 435 may have a matching surface 4351 inclined downward, and the first lower limit matching portion 943 may have an inclined surface 9431 (see Figure 2 ), when assembling the second adapter 94, insert the second adapter 94 from top to bottom into the hose reel mounting hole 433, and make the inclined surface 9431 of the first lower limit fitting part 943 contact and press against the fitting surface 4351 of the first lower limit part 435, and make the first lower limit part 435 and the first lower limit fitting part 943 deform, so that the first upper limit fitting part 942 can be inserted from top to bottom to the bottom of the first upper limit fitting part 434.

[0085] In addition to the above-mentioned embodiments, the second adapter 94 can also be installed on the hose reel mounting base 43 by other fixing methods, such as other forms of clamping, welding, bonding, screwing, etc.

[0086] For further information, please refer to Figure 2 as well as Figure 6 , 7 In some embodiments, in order to realize the rotatable connection between the hose reel 41 and the hose reel mounting seat 43, the hose reel 41 has a docking head 418, and the transfer channel 401 is arranged through the docking head 418, for example, at least a part of the vertical section 402 of the transfer channel 401 is arranged through the docking head 418. The docking head 418 is inserted into the hose reel mounting hole 433 and forms a rotatable connection with the hose reel mounting seat 43.

[0087] Please refer to Figure 2 as well as Figure 6 ,7 In some embodiments, a sinking platform 437 is provided in the hose reel mounting hole 433, and a through hole is left in the middle of the sinking platform 437 for the second adapter 94 to pass through. The docking joint 418 penetrates the through hole of the sinking platform 437 from bottom to top, and a clamping platform 4181 is provided on the peripheral side of the docking joint 418, and the clamping platform 4181 can be hung on the top wall of the sinking platform 437. The docking joint 418 is not limited in the rotation direction, so that the hose reel 41 can rotate relative to the hose reel mounting seat 43.

[0088] Please refer to Figure 2 as well as Figure 6 , 7 In some embodiments, the second adapter 94 is directly inserted into the docking joint 418 to form a sealed connection. The first lower limit portion 435 for limiting the second adapter 94 downward can also be set on the sinking platform 437. This structure not only realizes the fixed matching between the hose reel mounting seat 43 and the second adapter 94, but also completes the rotational connection between the hose reel 41 and the hose reel mounting seat 43, and also completes the sealed docking between the docking joint 418 of the hose reel 41 and the second adapter 94. The docking of multiple components is completed with a simple and compact structure, which improves the compactness of the structure. Moreover, the matching parts of the structure are mainly concentrated in the hose reel mounting hole 433 of the hose reel mounting seat 43. The hole wall of the hose reel mounting hole 433 can protect each matching part to avoid the impact of other components affecting the matching effect, thereby improving the reliability of matching.

[0089] Of course, in other embodiments, other structures may be used to connect the hose reel mounting base 43 and the hose reel 41, and the hose reel 41 and the second adapter 94, and are not limited to the structures described in the above embodiments.

[0090] Furthermore, usually in the process of pulling out the flushing pipeline 50, the user will expect that the flushing pipeline 50 can be locked at a set position, so that the user does not need to keep pulling the flushing pipeline 50. Therefore, in some embodiments, the hose reel device also has a hose reel self-locking component, which is used to lock the flushing pipeline 50 at a set position so that the flushing pipeline 50 can be kept at a certain pulled-out length. Of course, the hose reel self-locking component can also be unlocked, so that the hose reel device can automatically retract the flushing pipeline 50. The hose reel self-locking component can adopt the self-locking structure of a common hose reel or a wire reel, or the self-locking structure of a measuring tape, or other forms of self-locking structures.

[0091] In some embodiments, the top wall of the hose reel 41 is provided with a self-locking guide groove structure, and the hose reel mounting seat 43 has a top portion 431 disposed toward the top wall of the hose reel 41. The hose reel mounting seat 43 is provided with a hose reel self-locking assembly, which cooperates with the self-locking guide groove structure to lock the tube body 51 at a set pull-out position during the process of pulling out the tube body 51. The self-locking guide groove structure and the hose reel self-locking assembly can adopt any guide groove type self-locking structure, such as an existing labyrinth self-locking device.

[0092] Please refer to Figure 6 and 7 In some embodiments, a hose reel self-locking assembly 441 and a self-locking guide groove structure 419 are provided. The hose reel self-locking assembly 441 is rotatably mounted on the hose reel mounting seat 43 or other supporting components. The hose reel self-locking assembly 441 has a locking rod 4411, which extends into the self-locking guide groove structure 419 of the hose reel 41.

[0093] Please refer to Figure 8 and 9 In some embodiments, the self-locking guide groove structure 419 includes a first annular guide groove 4191 arranged around the rotation axis of the hose reel 41 and a second annular guide groove 4192 located on the inner circle of the first annular guide groove 4191, and the second annular guide groove 4192 is arranged cocentrically with the first annular guide groove 4191.

[0094] When the flushing pipeline 50 is pulled out, the rotation direction of the hose reel 41 is defined as the first direction; when the flushing pipeline 50 is recovered, the rotation direction of the hose reel 41 is defined as the second direction. The first direction is opposite to the second direction. The first direction can be the clockwise direction, in which case the second direction is the counterclockwise direction. The first direction can also be the counterclockwise direction, in which case the second direction is the clockwise direction.

[0095] The locking rod 4411 is configured to be able to slide in the self-locking guide groove structure 419, wherein when the hose reel 41 rotates, the hose reel 41 moves relative to the locking rod 4411, which is equivalent to the locking rod 4411 moving relative to the hose reel 41. In order to better describe the movement relationship between the locking rod 4411 and the hose reel 41, the description is made from the perspective of the locking rod 4411. When the flushing pipeline 50 is pulled out, the hose reel 41 rotates in the first direction, that is, the locking rod 4411 moves in the second direction relative to the hose reel 41, and the locking rod 4411 mainly moves in the first annular guide groove 4191. When the flushing pipeline 50 is recovered, the hose reel 41 rotates in the second direction, and the locking rod 4411 moves in the first direction relative to the hose reel 41, and the locking rod 4411 mainly moves in the second annular guide groove 4192.

[0096] Please refer to Figure 8 and 9When the flushing pipeline 50 is completely wound on the hose reel 41, the locking rod 4411 is in the second annular guide groove 4192. At this time, when the flushing pipeline 50 is pulled outward, the locking rod 4411 needs to move from the second annular guide groove 4192 to the first annular guide groove 4191 relative to the hose reel 41. Therefore, the self-locking guide groove structure 419 also includes a first connecting guide groove 4193 arranged between the second annular guide groove 4192 and the first annular guide groove 4191. When the flushing pipeline 50 is pulled outward, the locking rod 4411 can move from the first connecting guide groove 4193 to the first annular guide groove 4191 relative to the hose reel 41. In order to prevent the locking rod 4411 from moving from the first annular guide groove 4191 back to the first connecting guide groove 4193 relative to the hose reel 41, the first connecting guide groove 4193 is provided with a step-type limiting structure 4194a, which only allows the locking rod 4411 to move from the first connecting guide groove 4193 to the first annular guide groove 4191 relative to the hose reel 41.

[0097] The structure of the first annular guide groove 4191 is configured to allow the locking rod 4411 to freely move in the first annular guide groove 4191 relative to the hose reel 41 along the second direction, that is, when the locking rod 4411 is located in the first annular guide groove 4191, the hose reel 41 can continue to rotate in the first direction to release a longer flushing pipeline 50. At the same time, the structure of the first annular guide groove 4191 is also configured not to allow the locking rod 4411 to freely move in the first annular guide groove 4191 relative to the hose reel 41 along the first direction, that is, the first annular guide groove 4191 is provided with one or more limiting structures that prevent the locking rod 4411 from moving in the first annular guide groove 4191 relative to the hose reel 41 along the first direction. For example, in Figure 8 and 9In the illustrated embodiment, the bottom wall of the first annular guide groove 4191 is provided with a stepped limiting structure 4194b, which prevents the locking rod 4411 from moving in the first annular guide groove 4191 relative to the hose reel 41 along the first direction, but allows the locking rod 4411 to move in the first annular guide groove 4191 relative to the hose reel 41 along the second direction, that is, when the flushing pipeline 50 is pulled out, the locking rod 4411 does not affect the rotation of the hose reel 41 along the first direction, but when the flushing pipeline 50 is stopped, the hose reel 41 is reset under the action of the hose reel elastic member 42, and at this time the hose reel 41 rotates in the second direction, and when the locking rod 4411 contacts the stepped limiting structure, it will prevent the hose reel 41 from continuing to rotate in the second direction. At this time, in order to better lock the hose reel 41, the self-locking guide groove structure 419 further includes at least one locking groove 4195, which is located on the inner side (the inner circle side) of the first annular guide groove 4191. The first annular guide groove 4191 is connected to the locking groove 4195, so that the locking rod 4411 can move from the first annular guide groove 4191 to the locking groove 4195 relative to the hose reel 41. The position of the stepped limiting structure 4194b corresponds to the locking groove 4195. Under the action of the hose reel elastic member 42, when the locking rod 4411 moves to the stepped limiting structure 4194b along the first direction relative to the hose reel 41, it moves along the guide surface of the stepped limiting structure 4194b to the locking groove 4195. The locking groove 4195 is configured to prevent the locking rod 4411 from moving in a first direction relative to the hose reel 41, but allows the locking rod 4411 to move in a second direction relative to the hose reel 41. That is, when the locking rod 4411 is located in the locking groove 4195, the hose reel 41 is locked, and the restoring force of the hose reel elastic member 42 cannot pull the flushing pipeline 50 back, unless the user pulls the flushing pipeline 50 again to disengage the locking rod 4411 from the locking groove 4195.

[0098] After the locking rod 4411 locks the hose reel 41, in order to allow the user to continue to pull out the flushing pipeline 50, the locking groove 4195 is also configured to be connected to the second annular guide groove 4192. When the user pulls the hose reel 41 to rotate again, the locking rod 4411 moves in the second direction relative to the hose reel 41, and moves from the locking groove 4195 to the second annular guide groove 4192, and then moves from the first connecting guide groove 4193 to the first annular guide groove 4191, repeating the aforementioned changes.

[0099] After the lock rod 4411 locks the hose reel 41, when it is necessary to recycle the flushing pipeline 50, the user can pull the hose reel 41 to rotate, so that the lock rod 4411 moves relative to the hose reel 41 in the second direction and moves from the locking groove 4195 to the second annular guide groove 4192. Then, the user releases the flushing pipeline 50, and the hose reel 41 rotates in the second direction under the action of the hose reel elastic member 42, and the lock rod 4411 moves relative to the hose reel 41 in the first direction. In order to allow the hose reel 41 to pull the flushing pipeline 50 back more freely, the structure of the second annular guide groove 4192 is configured to allow the lock rod 4411 to freely move relative to the hose reel 41 in the second annular guide groove 4192 in the first direction, that is, when the lock rod 4411 is located in the second annular guide groove 4192, the hose reel 41 can continue to rotate in the second direction to recycle the flushing pipeline 50.

[0100] Please refer to Figure 8 and 9 In some embodiments, when the locking rod 4411 moves from the second annular guide groove 4192 to the first connecting guide groove 4193 relative to the hose reel 41, the bottom wall of the second annular guide groove 4192 is provided with a step-type limiting structure 4194c, so that when the locking rod 4411 moves along the second direction in the second annular guide groove 4192 to the first connecting guide groove 4193, it can only enter the first connecting guide groove 4193 and will not continue to move along the second direction in the second annular guide groove 4192.

[0101] Please refer to Figure 8 and 9 In some embodiments, when the locking rod 4411 is self-locked in the locking groove 4195, when the user pulls the flushing pipeline 50 again, in order to prevent the locking rod 4411 from returning to the first annular guide groove 4191 from the locking groove 4195, a step-type limiting structure 4194d is provided at the connection between the locking groove 4195 and the first annular guide groove 4191 to limit the locking rod 4411 from returning to the first annular guide groove 4191 from the locking groove 4195. When the locking rod 4411 enters the second annular guide groove 4192 from the locking groove 4195, in order to prevent the locking rod 4411 from returning to the locking groove 4195 from the second annular guide groove 4192, a step-type limiting structure 4194e is provided at the connection between the locking groove 4195 and the second annular guide groove 4192 to limit the locking rod 4411 from returning to the locking groove 4195 from the second annular guide groove 4192.

[0102] Furthermore, in some embodiments, each locking groove 4195 can provide a pipeline locking point, and the self-locking guide groove structure 419 can have one or more locking grooves 4195 to achieve one or two pipeline locking points. Figure 8 and 9In the illustrated embodiment, the two locking grooves 4195 are spaced approximately 180° apart in the circumferential direction to achieve the purpose of setting the flushing pipeline 50 at different lengths.

[0103] Of course, in other embodiments, the self-locking guide groove structure 419 may also adopt other structures cooperating with the locking rod 4411 to achieve self-locking and unlocking structures during the process of pulling out and retracting the pipeline, and is not limited to the structure shown in the above embodiment.

[0104] Please refer to Fig.10 and 11 In some embodiments, the hose reel self-locking assembly 441 further includes a locking rod connecting arm 4412, which is rotatably mounted on the hose reel mounting seat 43 or other components (such as the second separator 13). The locking rod 4411 is mounted on the locking rod connecting arm 4412, and when the locking rod 4411 moves in the self-locking guide groove structure 419, it can adaptively rotate around the hose reel mounting seat 43 or other components to adjust its position.

[0105] In some embodiments, at least one of the locking rod connecting arm 4412 and the locking rod 4411 is an elastic structure, so that the locking rod 4411 can adaptively adjust its position in the vertical direction when sliding relative to the self-locking guide groove structure 419. The elastic structure can be that at least one of the locking rod connecting arm 4412 and the locking rod 4411 is made of elastic material, or at least one of the locking rod connecting arm 4412 and the locking rod 4411 is supported by an elastic member (such as a spring) to form an elastic floating structure.

[0106] Please refer to Fig.10 and 11 In some embodiments, the locking rod connecting arm 4412 is made of elastic material and has elasticity itself. When the locking rod 4411 moves in the self-locking guide groove structure 419, the locking rod connecting arm 4412 can be deformed according to the position change of the locking rod 4411, and adaptively adjust the position of the locking rod 4411 relative to the self-locking guide groove structure 419.

[0107] Please refer to Fig.10 and 11 In some embodiments, the locking rod connecting arm 4412 and the locking rod 4411 are located above the self-locking guide groove structure 419, and the elastic force generated by them drives the locking rod 4411 to maintain a tendency to abut against the self-locking guide groove structure 419 downward, so as to ensure that the locking rod 4411 fits tightly with the self-locking guide groove structure 419.

[0108] Please refer to Figure 7 and 10In some embodiments, the top 431 of the hose reel mounting seat 43 has a movable groove 438 arranged radially along the self-locking guide groove structure 419, and the locking rod 4411 is arranged in the movable groove 438 so that the locking rod 4411 can adaptively adjust its position radially during the cooperation process with the self-locking guide groove structure 419.

[0109] For further information, please refer to Figure 7 , 10 In some embodiments, the locking rod connecting arm 4412 is located on the upper side of the top 431 of the hose reel mounting seat 43 and is rotatably disposed on the top 431 of the hose reel mounting seat 43. The locking rod 4411 is fixedly connected to the locking rod connecting arm 4412, and the locking rod 4411 passes through the top 431 of the hose reel mounting seat 43 and is inserted into the self-locking guide groove structure 419. When the locking rod 4411 moves relative to the self-locking guide groove structure 419, it changes up and down in the vertical direction, so a certain vertical space needs to be reserved for the locking rod 4411. In this embodiment, the locking rod 4411 is arranged to pass through the hose reel mounting seat 43, and a vertical space is reserved above the hose reel mounting seat 43 for the locking rod 4411 to move up and down, and there is no need to reserve the vertical space between the hose reel mounting seat 43 and the hose reel 41, so the hose reel mounting seat 43 can be as close to the hose reel 41 as possible, which plays a role in protecting the self-locking guide groove structure 419 and preventing foreign objects from falling into the self-locking guide groove structure 419 and affecting the movement of the locking rod 4411 in the self-locking guide groove structure 419. Of course, in other embodiments, the hose reel self-locking assembly 441 can also be integrally arranged on the bottom wall of the top 431 of the hose reel mounting seat 43, and is not arranged through the top 431.

[0110] When the locking rod 4411 is arranged to penetrate the hose reel mounting seat 43, in order to reduce the overall thickness of the hose reel mounting seat 43 and the hose reel self-locking assembly 441, in some embodiments, please refer to Fig.10 The top wall of the top 431 of the hose reel mounting seat 43 has a recessed area 439 , and the locking rod connecting arm 4412 is located in the recessed area 439 .

[0111] For further information, please refer to Fig.10 and 11In some embodiments, the hose reel self-locking assembly 441 further includes a support arm 4413, which is disposed opposite to the locking rod connecting arm 4412. The support arm 4413 is located at the inner side of the hose reel mounting seat 43, and is clamped on the hose reel mounting seat 43 together with the locking rod connecting arm 4412. The support arm 4413 and the locking rod connecting arm 4412 are connected by a rotating shaft 4414, and are integrally rotatably connected to the hose reel mounting seat 43 through the rotating shaft 4414.
