Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, in particular to a steam pipeline, a cleaning equipment and a cleaning system. BACKGROUND

[0002] With the continuous development of society, people's living standards are also getting higher and higher. Compared with traditional manual cleaning, a floor cleaning machine is more time-saving and labor-saving, and has been used by more and more families. The floor cleaning machine usually includes an equipment body and a cleaning base. The cleaning base includes a cleaning roller for mopping. Cleaning liquid is sprayed onto the cleaning roller through a water pipe, and the cleaning roller rotates at high speed to mop the floor.

[0003] Since the floor to be cleaned is usually dry, it is difficult to mop the adhering objects on the floor to be cleaned. Therefore, the floor to be cleaned can be first moistened by a liquid spraying assembly, and then the floor to be cleaned is mopped by the cleaning roller, so as to improve the mopping and cleaning effect of the cleaning on the floor. Therefore, it is necessary to improve the performance of the liquid spraying assembly.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0074] Embodiments of the present disclosure provide a cleaning system, such as Figures 1-3 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be a handheld scrubber, which is usually placed back to the base station 20 after use, and is docked and supported by the base station 20. The cleaning device 10 can be self-cleaned on the base station 20, such as automatic cleaning of the cleaning roller 122 on the cleaning device 10.

[0075] It should be noted that the cleaning device 10 described in the present disclosure is only a preferred embodiment of the present disclosure, and is not a limitation on the scope of protection of the cleaning device 10 of the present disclosure. For example, the cleaning device 10 of the present disclosure can be a handheld scrubber with a handle and manually operated by a user. It can also be an autonomous mop robot with driving wheels, which can control the driving wheels to move according to the program stored therein, and control the cleaning roller 122 to clean the ground. For another example, the cleaning device 10 of the present disclosure can also be a mop, a sweeper, an electric mop, or other cleaning devices.

[0076] In the following, the cleaning device 10 in the embodiments of the present disclosure will be described in detail taking the cleaning device 10 as a handheld scrubber as an example.

[0077] In an embodiment, as shown in Figure 3 and Figure 4As shown, the cleaning device 10 comprises a machine body 110 and a cleaning base 120. The machine body 110 comprises opposite first and second ends along its length direction, and the cleaning base 120 is connected to the second end of the machine body 110. The cleaning base 120 is provided with a liquid supply tank 111, and the liquid supply tank 111 is provided with a clean water injection port 1111 and a cleaning liquid injection port 1112. The machine body 110 is provided with a sewage tank 112 and a handle assembly 113, and the handle assembly 113 is connected to the first end of the machine body 110 away from the cleaning base 120 for the user to hold and operate. The user holds and operates the handle assembly 113 to control the movement of the cleaning base 120 on the surface to be cleaned, so as to achieve the cleaning purpose of the surface to be cleaned. In other embodiments, the liquid supply tank can also be provided on the machine body 110 together with the sewage tank 112.

[0078] In the embodiment, the cleaning base 120 is hinged to the device body, for example, is pivotally connected, or is connected by a ball joint, etc. When the user holds and operates the handle assembly 113 to control the movement of the cleaning base 120 on the surface to be cleaned, the relative angle between the device body and the cleaning base 120 can be adjusted by hinging the cleaning base 120 to the device body, so as to change the operation angle and flexibly adjust the cleaning posture, thereby facilitating the cleaning operation.

[0079] In the embodiment, as shown in the figure, Figure 4 The cleaning base 120 comprises a base shell 121, and the cleaning roller 122 is arranged on the bottom wall of the base shell 121 and exposed from the bottom wall. The bottom surface of the cleaning roller 122 is closer to the surface to be cleaned than the bottom wall of the base shell 121, so that when the cleaning roller 122 contacts the surface to be cleaned, there is a gap between the bottom wall of the base shell 121 and the surface to be cleaned, thereby preventing the base shell 121 from being abraded. The number of cleaning rollers 122 is one, two or more, for example. The cleaning roller 122 can rotate at a high speed to mop the floor. The cleaning roller 122 can be composed of a rotating shaft and a cleaning cloth wrapped around the surface of the rotating shaft. The rotating shaft rotates at a high speed under the drive to drive the cleaning cloth to rotate at a high speed, thereby performing high-speed rotational friction cleaning on the surface to be cleaned. The cleaning cloth can be detachably connected to the rotating shaft, thereby facilitating the replacement of the cleaning cloth and improving the maintenance economy of the cleaning roller 122.

[0080] In the embodiment, as shown in the figure, Figure 4As shown, a roller 123 is provided at the bottom of the cleaning base 120. The roller 123 is located on the side of the bottom of the cleaning base 120 away from the cleaning roller 122. The roller shaft of the roller 123 can be arranged parallel to the rotation shaft of the cleaning roller 122. By setting the roller 123, it plays an auxiliary role in moving the cleaning base 120 on the surface to be cleaned when the user operates it, thus avoiding friction between the base housing 121 and the surface to be cleaned. At the same time, an auxiliary wheel can be set at the bottom of the cleaning base 120 near the cleaning roller 122. The auxiliary wheel has a smaller diameter than the roller 123, which plays a role in assisting the movement of the cleaning base 120 and the rotation of the cleaning roller 122. The auxiliary wheel can provide support for the base housing 121 near the cleaning roller 122, reducing the resistance when the user operates the cleaning base 120.

[0081] Specifically, when the cleaning equipment 10 mops the ground with the cleaning roller 122, the ground to be cleaned is usually quite dry, making it difficult to remove the attached substances. Therefore, the ground to be cleaned can be moistened first, and then the cleaning roller 122 can be used to mop the ground, thereby improving the mopping and cleaning effect of the cleaning roller 122 on the ground.

[0082] Among them, such as Figures 4-6 As shown, in the forward direction of the cleaning device 10, a spraying assembly 124 is provided at the front end of the cleaning base 120, and a plurality of spray nozzles 1241 are formed on the spraying assembly 124. The surface to be cleaned can be moistened through the plurality of spray nozzles 1241 on the spraying assembly 124, and then the cleaning roller 122 behind the spraying assembly 124 mops and washes the moistened surface, thereby improving the mopping and cleaning effect of the floor.

[0083] The system sprays hot cleaning liquid or hot steam from the spray assembly 124 onto the surface to be cleaned, enhancing the wetting effect and thus improving the cleaning performance. The cleaning liquid can be water or a mixture of water and a cleaning agent.

[0084] Specifically, such as Figure 5 and Figure 6 As shown, the cleaning base 120 is provided with a steam pipe 130 to supply hot cleaning liquid or hot steam to the spray assembly 124.

[0085] Typically, when providing hot cleaning fluid or hot steam, the same heater heats the cleaning fluid. When there is a large amount of cleaning fluid, heating produces hot water; when there is a small amount of cleaning fluid, heating produces steam. However, because the same heater is used, when hot water is output, the heater cavity will be full. At this time, when switching to steam mode, due to the imbalance between heating energy and water volume, some water will be incompletely heated and ejected with the steam, affecting the functional effect.

[0086] Therefore, the steam pipeline 130 needs a steam-water separation structure to separate water from steam, so that the steam in the steam pipeline 130 is sprayed out of the spray port of the spray assembly 124, and the water in the steam pipeline 130 flows out of other paths.

[0087] To this end, the present disclosure provides a steam pipeline, such as Figures 7-15 As shown, the steam pipeline 130 includes a cavity 1331 and a float 134, the cavity 1331 includes an inlet 1332, an outlet 1333, and a water outlet 1330, the float 134 is arranged in the cavity 1331 and located at the water outlet 1330, and the float 134 can be in a first state and a second state in the cavity 1331, in the first state, the float 134 can completely abut against the water outlet 1330, that is, it can block the water outlet 1330 by using its own gravity, and when the accumulated water in the cavity 1331 increases, the float 134 can be in the second state, the float 134 can float upward along the height direction Z of the cavity 1331 under the action of the buoyancy of the accumulated water, so that the float 134 and the water outlet 1330 have a passage for liquid flow, to open the water outlet 1330 to drain water.

[0088] The steam pipeline 130 provided by the present disclosure can pass through the cavity 1331 by the inlet 1332 of the cavity 1331, and spray out of the outlet 1333, when part of the water is not completely heated and sprayed out with the steam, the water enters the cavity 1331 through the inlet 1332 of the cavity 1331 and accumulates in the cavity 1331, and the cavity 1331 forms a separation of steam and water, thereby avoiding the influence of water on the effect of steam spraying out, and improving the effect of steam pipeline 130. When there is no accumulated water or less accumulated water in the cavity 1331, the float 134 is in the first state as shown in Figure 13 When the accumulated water in the cavity 1331 increases, the float 134 floats upward along the height direction Z of the cavity 1331 under the action of the buoyancy of the accumulated water to be in the second state as shown in Figure 14 To open the water outlet 1330 to drain the accumulated water in the cavity 1331, and after the accumulated water is drained, the float 134 re-blocks the water outlet 1330 under the action of its own gravity.

[0089] In an embodiment, the steam pipeline 130 includes a first pipeline 131, a steam-water separation piece 133, and a second pipeline 132, the steam-water separation piece 133 is formed with the cavity 1331 of the inlet 1332, the outlet 1333, and the water outlet 1330, the first pipeline 131 is in communication with the inlet 1332 of the steam-water separation piece 133, the second pipeline 132 is connected with the outlet 1333 of the steam-water separation piece 133, and the float 134 is located in the cavity 1331.

[0090] The steam-water separation piece 133 can be provided with an inlet joint and an outlet joint 1334. The first pipeline 131 is connected to the inlet joint, and the second pipeline 132 is connected to the outlet joint 1334, which facilitates the assembly of the steam pipeline 130 and the later maintenance.

[0091] The first pipeline 131 and the second pipeline 132 can be flat tubes, which avoids occupying too much space at the height of the cleaning base 120 and facilitates the arrangement in the installation space formed by the shell of the cleaning base 120. At the same time, the use of flat tubes can improve the laminar flow effect of steam and water in the pipeline, so as to reduce the noise when the hot steam flows. Of course, the first pipeline 131 and the second pipeline 132 can also be round tubes or other shaped pipelines, and the present disclosure does not limit this.

[0092] As shown in Figure 16 and Figure 17 The steam-water separation piece 133 can be formed by buckling an upper shell 1335 and a bottom shell 1336. The shell of the steam-water separation piece 133 is formed by connecting the split structure, which facilitates the assembly of the float 134 in the steam-water separation piece 133, facilitates the assembly of the steam pipeline 130 and the later maintenance, and reduces the production cost. When the upper shell 1335 and the bottom shell 1336 are buckled to form the shell of the steam-water separation piece 133, a sealing ring 1256 can be arranged between the upper shell 1335 and the bottom shell 1336 to improve the air tightness between the upper shell 1335 and the bottom shell 1336, so as to avoid the leakage of hot steam from the joint between the upper shell 1335 and the bottom shell 1336, thereby avoiding affecting the effect of steam spraying.

[0093] As shown in Figure 16 and Figure 17 The first pipeline 131 can be formed by buckling the upper shell 1335 and the bottom shell 1336, that is, the first pipeline 131 and the steam-water separation piece 133 can be an integral molding structure. As shown in Figure 13 The outlet joint 1334 can be an integral molding structure with the bottom shell 1336.

[0094] As shown in Figure 16 and Figure 17As shown, the bottom shell 1336 can form a receiving space with an open end, and the upper shell 1335 is in the form of a cover plate, and the receiving cavity 1331 is formed by covering the open end of the bottom shell 1336 with the upper shell 1335. By forming the bottom shell 1336 into a receiving space with a certain depth, the assembly of the float 134 is facilitated due to the presence of gravity. Of course, the upper shell 1335 can form a receiving space with an open end, and the bottom shell 1336 is in the form of a cover plate, and the receiving cavity 1331 is formed by covering the open end of the bottom shell 1336 with the upper shell 1335; or the upper shell 1335 and the bottom shell 1336 can both form a receiving space with an open end, and the receiving space is communicated to form the receiving cavity 1331 after the upper shell 1335 and the bottom shell 1336 are buckled, and the present disclosure does not limit this.

[0095] In an embodiment, as shown in Figure 13 and Figure 14 In the height direction Z of the receiving cavity 1331, the drain port 1330 is located at the bottom of the receiving cavity 1331, and the float 134 is located above the drain port 1330. That is, in the height direction Z of the steam-water separation piece 133, the drain port 1330 can be located at the bottom of the steam-water separation piece 133, that is, at the lowest point of the steam-water separation piece 133, which is beneficial to the water in the receiving cavity 1331 being discharged through the drain port 1330.

[0096] In an embodiment, in the first state, in the height direction Z, the lowest point of the float 134 is higher than the bottom of the receiving cavity 1331, that is, the float 134 does not directly contact the bottom of the receiving cavity 1331, which avoids the float being adhered to the bottom of the receiving cavity 1331.

[0097] As shown in Figure 13 and Figure 14 As shown, a boss 1337 surrounding the drain port 1330 is arranged in the receiving cavity 1331, and the float 134 seals the drain port 1330 by abutting against the boss 1337. By arranging the boss 1337, the float 134 does not directly contact the bottom of the receiving cavity 1331, thereby avoiding the situation that when a small amount of liquid appears at the bottom of the receiving cavity 1331, the float 134 can be adhered to the bottom of the receiving cavity 1331, and even if the amount of water accumulated in the receiving cavity 1331 reaches the threshold value, the float 134 can not be normally floated, and the water at the bottom of the receiving cavity 1331 cannot be discharged. In the height direction Z, the boss can have a height of 1mm-2mm, such as 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, and the like, which are not enumerated one by one in the present disclosure.

[0098] In an embodiment, the drain port 1330 can be provided with a drain nozzle extending downwardly on the outer surface of the bottom shell 1336 to guide the water to drain, avoiding the overflow of the water discharged through the bottom shell 1336 of the steam-water separation piece 133 to other components. The drain nozzle can be arranged opposite to the cleaning roller 122, i.e. the water discharged through the drain nozzle can directly fall on the cleaning roller 122 to wet the cleaning roller 122. Of course, the drain nozzle can also be arranged opposite to the inlet 1332 of the suction channel on the cleaning base 120, and the water discharged can be recycled to the sewage tank 112 through the suction channel.

[0099] In an embodiment, the steam pipeline 130 further comprises a reset piece 135. When there is no or less water accumulated in the containing cavity 1331, the float 134 blocks the drain port 1330 under the reset force of the reset piece 135, avoiding the steam from leaking out through the drain port 1330; when the water accumulated in the containing cavity 1331 increases, the float 134 can overcome the reset force of the reset piece 135 and float upward along the height direction Z of the containing cavity 1331 to open the drain port 1330 to discharge the water accumulated in the containing cavity 1331; after the water accumulated is discharged, the float 134 re-blocks the drain port 1330 under the reset force of the reset piece 135.

[0100] In an embodiment, the reset piece 135 is an elastic piece, i.e. the float 134 blocks the drain port 1330 under the elastic force, or overcomes the elastic force and moves upward along the height direction Z of the steam-water separation piece 133 to open the drain port 1330 by the buoyancy. The reset force provided by the elastic piece is relatively stable, and the reset force does not easily decay after long-term use, so that the reliability of the reset piece 135 is relatively high, and the service life can reach the full service life cycle of the cleaning equipment 10.

[0101] The elastic piece can be a spring. The elastic force provided by the spring is relatively linear, which can provide a stable and reliable reset force to the float 134. The elastic force provided by the spring is not affected by high-temperature steam and hot cleaning liquid, and has a relatively long service life. At the same time, the spring has a simple structure, is easy to install, and has a relatively light mass, which can avoid the reset piece 135 from occupying excessive space. Of course, the elastic piece can also be an elastic rubber block or a hydraulic mechanism, which is not limited in the present disclosure.

[0102] When the float 134 blocks the drain port 1330, the elastic piece is in a compressed state, i.e. the elastic piece provides a certain pre-tightening force to the float 134, so that the float 134 is in close contact with the drain port 1330 to improve the sealing effect. When the buoyancy of the water accumulated in the containing cavity 1331 to the float 134 is greater than the downward pre-tightening force and the gravity, the float 134 overcomes the elastic force of the elastic piece and the gravity to float upward to open the drain port 1330 to drain water.

[0103] In the height direction Z of the cavity 1331, the reset member 135 is disposed on the upper part or the lower part of the float 134, or both. When the reset member 135 is disposed on the upper part of the float 134, the reset member 135 may be, for example, a spring; when the reset member 135 is disposed on the lower part of the float 134, the reset member 135 may be, for example, a tension spring, that is, when the reset member 135 is subjected to buoyancy and moves upward, the tension spring needs to be continuously stretched; when the reset member 135 is disposed on both the upper and lower parts of the float 134, that is, a spring may be disposed on the upper part of the reset member 135 and a tension spring may be disposed on the lower part.

[0104] In one embodiment, a limiting structure is formed on the inner wall of the housing of the steam pipe 130, and one end of the elastic element is limited and connected to the housing through the limiting structure to form a positioning assembly for the elastic element, thereby improving the stability of the restoring force provided by the elastic element.

[0105] Among them, a limiting structure is formed on the inner wall of the upper shell 1335 of the steam-water separator 133, that is, one end of the elastic element is limited and connected to the inner wall of the upper shell 1335, and the other end abuts against the float 134, which is equivalent to the elastic element being clamped between the upper shell 1335 and the float 134.

[0106] Among them, such as Figure 16 As shown, a limiting protrusion 136 is formed on the inner wall of the upper shell 1335 of the steam-water separator 133. One end of the spring is sleeved on the limiting protrusion 136, and the other end abuts against the float 134. The limiting protrusion 136 forms a limiting assembly for the elasticity in its radial direction, so that it can only be withdrawn from the limiting protrusion 136 in the axial direction, which facilitates assembly.

[0107] In one embodiment, the float 134 includes one of a cube, a prism, a sphere, a frustum, or a pyramid. Figure 18 As shown, float 134 is a cylinder. The end face of the cylinder provides a good seal for the drain outlet 1330. When float 134 is a sphere, the spherical surface of the float provides a good seal for the drain outlet 1330, and the float 134 maintains a good seal even after rotating in any direction, thus improving the sealing effect. Simultaneously, the sphere occupies less space and is more sensitive to buoyancy, allowing it to overcome the resetting force of the reset member 135 and float upwards along the height Z direction of the cavity 1331 when the water accumulation in the cavity 1331 increases, thereby opening the drain outlet 1330 and draining the accumulated water from the cavity 1331.

[0108] The float 134 can be a hollow structure to reduce its own weight and improve its response sensitivity to the buoyancy provided by the accumulated water. Of course, the float 134 can also be a solid structure, and this disclosure does not limit it.

[0109] In one embodiment, such as Figure 19As shown, the float 134 is arranged in a staggered manner with the inlet 1332 in the width direction Y of the accommodating cavity 1331. By arranging the float 134 in a staggered manner with the inlet 1332, the function of the float 134 is prevented from being affected by too much steam directly sprayed onto the float 134, thereby avoiding the situation that the float 134 directly floats up due to too much steam, and the steam is sprayed from the drain port 1330.

[0110] Further, the float 134 is arranged in a staggered manner with the outlet 1333 in the width direction Y of the accommodating cavity 1331, and the inlet 1332 and the outlet 1333 are located on the same side of the float 134, that is, the inlet 1332 and the outlet 1333 are located on both sides of the float 134 along the length direction X of the accommodating cavity 1331, and the inlet 1332 and the outlet 1333 are located on one side of the float 134 along the width direction Y, so that the float 134 basically does not affect the flow of gas or liquid in the accommodating cavity 1331.

[0111] Among them, the inlet 1332 and the outlet 1333 are arranged in a staggered manner in the width direction Y of the accommodating cavity 1331, so as to avoid that the steam mixed with water sprayed into the inlet 1332 is directly sprayed to the outlet 1333, thereby improving the steam-water separation effect.

[0112] In an embodiment, the steam pipeline 130 further comprises a guide structure located in the accommodating cavity 1331; the guide structure is configured to guide the movement of the float 134 towards the position of blocking the drain port 1330 and the upward floating movement, thereby improving the stability of the float 134 when moving and avoiding the float 134 deviating and unable to effectively drain the drain port 1330.

[0113] In an embodiment, the guide structure comprises a sliding groove and a sliding block, one of the sliding groove and the sliding block is arranged on the float 134, and the other is arranged in the accommodating cavity 1331, and the sliding block is located in the sliding groove. For example, as shown in Figure 17 As shown, the sliding block 1371 is arranged on the side wall of the bottom shell 1336, and as shown in Figure 18 As shown, the sliding groove 1372 is arranged on the side surface of the float 134, so that the float 134 can only move along the height direction Z in the accommodating cavity 1331.

[0114] Among them, the side wall of the bottom shell 1336 can be respectively provided with a sliding block 1371 on both sides of the length direction X, and the float 134 is provided with two symmetrical sliding grooves 1372 on the side surface, and the two sliding blocks 1371 are correspondingly located in the two sliding grooves 1372, thereby guiding the movement of the float 134 in the height direction Z and limiting the rotation of the float 134 in the circumferential direction. Of course, three, four or more sliding blocks 1371 can be arranged to cooperate with multiple sliding grooves 1372, and the present disclosure does not limit this.

[0115] In an embodiment, as shown in Figure 19As shown, in the width direction Y, the drain port 1330 is offset on one side of the cavity 1331, and a protruding structure 139 is arranged on the other side of the cavity 1331. By arranging the protruding structure 139, that is, the height of the side of the bottom of the cavity 1331 away from the drain port 1330 is higher, so that the accumulated water can flow towards the drain port 1330, thereby being able to timely drain the accumulated water in the cavity 1331.

[0116] Among them, the side wall of the protruding structure 139 near the side of the drain port 1330 can be a slope, which is beneficial to the flow of accumulated water.

[0117] In an embodiment, a flow guide structure is arranged in the cavity 1331, and in the horizontal direction, that is, in the width direction Y and the length direction X, the flow guide structure and the cavity 1331 have a gap; the flow guide structure is located near the inlet 1332, and in the width direction Y, the width of the flow guide structure is greater than or equal to the width of the inlet 1332; preferably, the width of the flow guide structure is slightly greater than the width of the inlet 1332, for example, the width difference is within 5mm; or, the flow guide structure is located near the outlet 1333, and in the width direction Y, the width of the flow guide structure is greater than or equal to the width of the outlet 1333; preferably, the width of the flow guide structure is slightly greater than the width of the outlet 1333, for example, the width difference is within 5mm. By arranging the flow guide structure, the steam flow path is improved, so as to avoid the steam mixed with water sprayed by the inlet 1332 directly sprayed to the outlet 1333, thereby improving the steam-water separation effect. Among them, the flow guide structure is located near the inlet 1332 or the outlet 1333, for example, the distance between the flow guide structure and the inlet 1332 or the outlet 1333 is less than 10mm.

[0118] In an embodiment, as shown in Figure 15 and Figure 16 , a first flow guide plate 1381 is arranged in the cavity 1331, and the first flow guide plate 1381 is located between the inlet 1332 and the outlet 1333; in the height direction Z, the first flow guide plate 1381 and the bottom of the cavity 1331 are arranged in a spaced manner. By arranging the first flow guide plate 1381, the steam flow path in the cavity 1331 is increased, thereby improving the steam-water separation effect of the steam.

[0119] Among them, the first flow guide plate 1381 is arranged at the top of the cavity 1331, as shown in Figure 16 , the first flow guide plate 1381 is connected with the upper shell 1335, and can be in an integral molding structure with the upper shell 1335. Among them, the first flow guide plate 1381 can form a side plate part on both sides in the width direction Y, further forming a guide for the steam flow.

In the height direction Z, one side of the second flow guide plate 1382 is spaced apart from the top of the cavity 1331.
