Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort fall within the scope of the present disclosure.

Without more limitation, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the goods or devices including the element.

[0033] In the related art, water equipment usually needs hot water for the convenience of drinking or cleaning stubborn stains, and in cleaning equipment, even steam is used for auxiliary cleaning, so that the pile structure usually has a heating device. Since the tap water commonly used in families contains natural impurities, even a large amount of calcium ions and magnesium ions, after the calcium and magnesium ions are heated into hot water or water vapor by the heating device, they will condense into scale, which will not only affect the heating effect of the heating device after a long time, but even after the scale accumulates, it will block the water outlet, causing the heating function or the water outlet function to fail, affecting the user's experience.

[0034] To solve the above technical problems, the present disclosure provides a pile structure, comprising: a fluid conveying assembly configured to convey clean water to a cleaning device; a heating assembly configured to heat the clean water; a filter assembly detachably arranged in the pile structure and configured to filter the clean water before heating and / or filter the clean water after heating.

[0035] The pile structure, the cleaning pile and the cleaning system provided by the present disclosure have a filter assembly. The filter assembly can filter the clean water before and / or after the clean water is heated, so that the impurities in the clean water are reduced, and the clean water is prevented from being polluted by the impurities, or the heating assembly is prevented from being disabled due to scale blocking the pipeline, or the water outlet pipeline is prevented from being blocked. In addition, the filter assembly is detachably connected to the pile structure, so that the filter assembly can be replaced in time, the service life of the pile structure is prolonged, and the user experience is improved.

[0036] In view of this, the optional embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0037] The first aspect of the embodiments of the present disclosure provides a pile structure 100, which comprises a water flow pipeline, a first fluid conveying assembly 120, a heating assembly 140 and a filter assembly 130. As shown in FIG. 1, the water flow pipeline is provided with a water source inlet 110, and the first fluid conveying assembly 120 is arranged near the external water source inlet 110 and configured to convey external clean water into the water flow pipeline. The first fluid conveying assembly can be a water pump or a fluid booster. In actual application, since the water-using equipment 200 connected to the pile structure 100 has a demand for using hot water for cleaning or drinking, the pile structure 100 is further provided with the heating assembly 140, which is arranged on the side of the first fluid conveying assembly 120 away from the water source inlet 110 and configured to convey the external water source to the heating assembly 140, so that the pile structure 100 can provide hot water for the water-using equipment 200. The clean water can be heated to 60-80℃ by the heating assembly 140. The water source inlet 110 can be an external water source directly introduced into the pile structure 100 from outside, or a clean water tank of a cleaning equipment base station.

[0038] In some embodiments, the pile structure 100 is further provided with the filter assembly 130, which is detachably arranged in the pile structure 100 and configured to filter the clean water before heating, or to filter the clean water after heating, or to filter the clean water before heating and after heating at the same time. Not only the impurities in the water flow pipeline are reduced, but also the scale generated after heating is filtered, so that the scale is prevented from blocking the water flow or affecting the normal work of the heating assembly 140.

[0039] Specifically, as shown in FIG. 2, the filter assembly 130 comprises a first filter structure 131 arranged between the first fluid conveying assembly 120 and the heating assembly 140 and configured to filter the impurities in the first particle size range in the clean water. The impurities in the first particle size range include impurities such as silt, particles, dust, suspended matter and rust with relatively large size.

[0040] In some embodiments, the first filter structure 131 can be a fiber filter core. The fiber filter core can be a rotor wing structure, forming a pore in the inside of the pile structure 100, gradually reducing from top to bottom, forming an ideal filter bed with a gradient distribution of large at the top and small at the bottom, which is beneficial for the effective separation of solid suspended matter in water. Solid suspended matter with a larger particle size will be trapped at the upper part, while solid suspended matter with a smaller particle size that fails to be trapped will continue to flow downward. Due to the gradually decreasing voids of the fiber filter core filter bed, impurities with a particle size within a first particle size range can be filtered. The filter bed of the fiber filter core not only has high precision of filtration, but also has high filtration speed. Since the rotor wing fiber filter material has rotor wings, the rotor wings drive the fiber bundles to rotate insufficiently, sway, and collide with each other, thereby greatly accelerating the separation of suspended particles attached to the fiber bundles, improving the cleaning speed of the filter material, saving water consumption for backwashing, and saving energy for backwashing. The fiber filter core can remove organic matter, bacteria, odors, organic pigments, residual chlorine, organic matter, and organic chemicals in clean water, while preventing carbon particles and small pollutants from flowing out.

[0041] In some embodiments, the first filter structure 131 can be an activated carbon filter core. The activated carbon filter core is made of high-quality nutshell carbon and coal-based activated carbon as raw materials, supplemented with a binder, and processed by a special process. It integrates adsorption, filtration, interception, and catalysis, can effectively remove organic matter, residual chlorine, and other radioactive substances in water, and has the functions of decolorization and odor removal. It can effectively purify the clean water in the pile structure 100 to make the clean water as clean as possible for the water using equipment 200.

[0042] In some embodiments, the first filter structure 131 can include a softening ion layer configured to soften hard water. Hard water softening is a process of removing calcium, magnesium, and other soluble salts in hard water. For example, the softening ion can be a sodium ion, which replaces calcium and magnesium ions in water. Since the solubility of sodium salt is very high, the generation of scale due to the increase in temperature is avoided. In response to the flow of clean water through the softening ion layer, the softening ion dissolves in the clean water and combines with heavy metals such as calcium and magnesium ions in the water to precipitate, achieving softening of the clean water. At the same time, the precipitate flows with the water flow and is configured to be filtered out under the action of the filter assembly 130.

[0043] In some embodiments, the filter assembly 130 includes a second filter structure 132, which is arranged between the first filter structure 131 and the heating assembly 140 and is configured to filter impurities in the clean water within a second particle size range.

[0044] The second filtering structure 132 is arranged downstream of the first filtering structure 131, and the first particle size is greater than the second particle size. After the clean water flows through the first filtering structure 131 to achieve the first filtration, the clean water flows to the second filtering structure 132. The second filtering structure 132 is a re-filtering of the first filtering structure 131, and is configured to filter and remove foreign colors, odors, residual chlorine, chloroform, and very fine silt, suspended solids, and colloids in the water. The second filtering structure 132 is configured to further filter the clean water to avoid excessive scale deposition affecting the heating rate or scale blocking the pipeline causing poor water flow.

[0045] In some embodiments, the second filtering structure 132 can be a polypropylene fiber filter core, i.e., a PP fiber filter core. The PP fiber filter core is made of ultra-fine polypropylene fibers hot-melt entangled, and the ultra-fine fibers rely on self-adhesion and entanglement to form a three-dimensional microporous structure in space, with deep filtration characteristics, which can effectively remove various particulate impurities in the filtered liquid. It has the characteristics of large flow, corrosion resistance, high pressure resistance, low cost, etc.

[0046] In some embodiments, the filtering assembly 130 includes a third filtering structure 133 arranged between the second filtering structure 132 and the heating assembly 140, and configured to soften the clean water. Specifically, the third filtering structure 133 can be an ion membrane filtering structure, which uses the principle of reverse osmosis to remove harmful impurities such as bacteria, viruses, pollutants, medicaments, heavy metals (such as calcium and magnesium ions, etc.), and salts in water.

[0047] In some embodiments, the third filtering structure 133 can also be replaced by other devices that can soften hard water, such as the softening ion layer described in the above embodiments. In response to the clean water flowing through the third filtering structure 133, the softening ions on the surface of the third filtering structure 133 dissolve in the clean water and combine with heavy metals such as calcium and magnesium ions in the water to precipitate, achieving softening of the clean water. At the same time, the precipitate flows with the water flow, and is configured to be filtered out under the action of the filtering assembly 130.

[0048] In some embodiments, the third filter structure 133 comprises a first filter layer, a second filter layer and a third filter layer. The first filter layer is a softening ion-attached layer or a semi-permeable membrane, configured to soften calcium and magnesium ions in the clean water. The second filter layer is configured to filter the softened clean water once. The third filter layer is arranged downstream of the second filter layer and is configured to filter the clean water again after the calcium and magnesium ions in the clean water fully react with the softening ions to form precipitates. Thus, after the clean water from an external water source flows into the water flow pipeline, it successively passes through the first filter structure 131, the second filter structure 132, the third filter structure 133 and the heating assembly 140, realizing twice softening and at least twice filtering. Not only can the clean water be fully softened, but also the impurity content in the clean water is guaranteed to be the lowest, ensuring the safety of the user and improving the service life of the pile structure 100.

[0049] In some embodiments, the filter assembly 130 further comprises a fourth filter structure 134 arranged on the downstream side of the heating assembly 140 and configured to filter scale in the heated clean water. Since the clean water successively flows through the first filter structure 131, the second filter structure 132 and the third filter structure 133 all before the heating assembly 140, the residual heavy metal impurities in the clean water may still react to form scale at high temperatures after the clean water flows through the heating assembly 140 and is heated and warmed. Therefore, the fourth filter structure 134 is arranged on the downstream side of the heating assembly 140, and in response to the water flow flowing out of the heating assembly 140, the fourth filter structure 134 filters the clean water again to avoid the residual scale in the clean water flowing to the next link.

[0050] In some embodiments, the pile structure 100 further comprises a water replenishing structure 150 arranged inside the pile structure 100 and selectively in communication with the external water-using device 200, configured to provide softened and filtered clean water to the water-using device 200. When the water flow pipeline is in communication with the water replenishing structure 150, the clean water can flow to the water replenishing structure 150 after being filtered by the filter assembly 130, and further, in response to the water-using device 200 being in communication with the water replenishing structure 150, the clean water flows from the water replenishing structure 150 to the inside of the water-using device 200. The water-using device 200 can be a cleaning device, a water dispenser, etc.

[0051] In some embodiments, the pile structure 100 also has a self-cleaning function. Specifically, the pile structure 100 is internally provided with a self-cleaning assembly 160 that is in communication with the water flow pipeline and is configured to receive filtered or heated clean water and use the clean water to clean the cleaning head of the water-using device 200. Through the self-cleaning function, residual scale or impurities on the surface of the cleaning head can be removed to ensure that the water-using device 200 can use clean and uncontaminated clean water.

[0052] In some embodiments, the pile structure 100 further includes a first reversing valve 170 provided in the water flow pipeline and configured to change the flow direction of the clean water to connect the water flow pipeline with the water replenishing structure 150 or the self-cleaning assembly 160. The reversing valve has a first adjustment gear and a second adjustment gear. In response to the first reversing valve 170 being in the first adjustment gear, the water flow pipeline is in communication with the water replenishing structure 150, at which time the pile structure 100 can supply water to the water-using device 200. In response to the first reversing valve 170 being in the second adjustment gear, the water flow pipeline is connected with the self-cleaning assembly 160, and the pile structure 100 can perform self-cleaning to ensure that the inner wall of the water flow pipeline is clean and free of impurities. In actual applications, the first reversing valve 170 can be switched between the first adjustment gear and the second adjustment gear through an electrical switch.

[0053] A second aspect of the embodiments of the present disclosure provides a cleaning pile including the pile structure 100 provided by the first aspect of the embodiments of the present disclosure.

[0054] In some embodiments, as shown in FIG. 2, the cleaning pile is configured to be actively connected with the cleaning device. In response to the cleaning device being connected with the cleaning pile, the clean water tank 210 of the cleaning device is in communication with the water replenishing structure 150 of the cleaning pile, and the cleaning pile is configured to supply water to the cleaning device. Specifically, the cleaning device is internally provided with a second fluid conveying assembly 220 configured to convey the clean water from the clean water tank 210 to the cleaning head or a steam generating assembly 250. Inside the cleaning device, there is a water-using element 240, which can be a cleaning roller brush, a cleaning head, etc. The clean water tank 210 is configured to provide hot water to the cleaning head. In actual applications, after the clean water heated by the cleaning pile is conveyed to the water-using element 240, the water-using element 240 can be more easily cleaned.

[0055] In some embodiments, the cleaning device is also internally provided with a steam generating assembly 250 that can heat the clean water conveyed by the second fluid conveying assembly 220 to 140°C or above to convert the clean water into water vapor for steam cleaning.

[0056] In some embodiments, the pile structure 100 further comprises a second reversing valve 230, which is arranged in the cleaning device and is configured to change the conveying direction of the water flow to convey the hot water to the water using element 240 or the steam generating assembly 250. The second reversing valve 230 has a third adjustment gear and a fourth adjustment gear. In response to the second reversing valve 230 being in the third adjustment gear, the hot water will flow to the water using element 240; in response to the second reversing valve 230 being in the fourth adjustment gear, the hot water will flow to the steam generating assembly 250. In practical applications, the second reversing valve 230 can be controlled by an electrical switch to switch between the third adjustment gear and the fourth adjustment gear to meet the use requirements of different users.

[0057] A third aspect of the embodiments of the present disclosure provides a cleaning system, which comprises a cleaning device and a cleaning pile according to the second aspect of the embodiments of the present disclosure. The cleaning pile is used to provide hot water for the cleaning device, and the water temperature of the hot water is 60-80 degrees.

[0058] In some embodiments, the cleaning device further comprises a steam generating assembly 250, which is in communication with the clean water tank 210 and is configured to convert the clean water in the clean water tank 210 into water vapor.

[0059] Specifically, the steam generating assembly 250 comprises a heating assembly 251, a steam injection assembly 252 and a third reversing valve 253. The heating assembly 251 is in communication with the clean water tank 210, and the clean water in the clean water tank 210 flows through the heating assembly 251 to form high-temperature steam, which is about 140℃. Further, the steam is sprayed out by the steam injection assembly 252 to supply the water using device 240. The third reversing valve 253 is arranged between the heating assembly 251 and the steam injection assembly 252 and is configured to control the flow of the steam pipeline.

[0060] The specific structure, working principle and beneficial effects of the pile structure, cleaning pile and cleaning system provided by the embodiments of the present disclosure can refer to those of any one of the above-mentioned embodiments, which will not be repeated here.

[0061] Finally, it should be noted that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the system or device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.
