[0117] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0118] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0119] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0120] like Figures 1 to 13 As shown, some embodiments provide a cleaning device 01. This cleaning device 01 can be a floor scrubber, a robotic vacuum cleaner, a vacuum and mop combo, etc., and this disclosure does not impose specific limitations on it. The cleaning device 01 has a good cleaning effect.

[0121] The cleaning device 01 may include a cleaning work unit 1. The cleaning work unit 1 can be used to clean the surface to be cleaned. The cleaning work unit 1 may include a cleaning component 13, a dispensing component 11, and a fluid output component 12.

[0122] The cleaning component 13 can contact the surface to be cleaned to clean the surface. The cleaning component 13 can be a roller brush, but is not limited to this. The cleaning component 13 can also be a brush strip, side brush, etc., and can be selected and set according to the actual situation. All of these are within the protection scope of this disclosure.

[0123] The cleaning device 01 can further comprise a normal-temperature cleaning liquid conveying flow path 2. The normal-temperature cleaning liquid conveying flow path 2 can be configured to convey normal-temperature cleaning liquid to the distribution member 11. The cleaning liquid can be clean water and / or a decontamination liquid or foam having a decontamination effect, etc. The normal-temperature cleaning liquid can be understood as cleaning liquid that has not been heated. The cleaning device 01 can have a normal-temperature cleaning mode, as shown by the solid arrow in FIG. 1A, that is, when cleaning the surface to be cleaned, the normal-temperature cleaning liquid conveying flow path 2 can be used to convey normal-temperature cleaning liquid to the distribution member 11, and the normal-temperature cleaning liquid can be used in cooperation with the cleaning working part 1 to clean, so as to improve the cleaning effect of the cleaning device 01. Figure 3

[0124] The distribution member 11 can be in communication with the normal-temperature cleaning liquid conveying flow path 2 to receive the normal-temperature cleaning liquid conveyed by the normal-temperature cleaning liquid conveying flow path 2. The distribution member 11 can convey the normal-temperature cleaning liquid to the cleaning member 13 to wet the cleaning member 13, so as to improve the cleaning ability of the cleaning member 13, thereby achieving the purpose of improving the cleaning effect of the cleaning device 01. Alternatively, the distribution member 11 can convey the normal-temperature cleaning liquid to the front of the cleaning member 13 to wet the dirt on the surface to be cleaned in front of the cleaning member 13, so that the dirt on the surface to be cleaned is easily cleaned by the cleaning member 13, thereby also achieving the purpose of improving the cleaning effect of the cleaning device 01.

[0125] It should be noted that the front of the cleaning member 13 described above refers to the front of the cleaning member 13 in the movement direction of the cleaning device 01.

[0126] The distribution member 11 can be a water strip, which can have a plurality of water outlets arranged at intervals to convey normal-temperature cleaning liquid to the cleaning member 13 or the surface to be cleaned. In this way, the water outlet range of the distribution member 11 can be improved, and the wetting range of the cleaning member 13 or the dirt can be further improved, thereby further improving the cleaning effect of the cleaning device 01. However, the distribution member 11 can also not be a water strip, and can also be another independent structure member capable of discharging water, or the distribution member 11 can also be a pipe end opening of the normal-temperature cleaning liquid conveying flow path 2, and the present disclosure does not limit the distribution member 11.

[0127] The cleaning device 01 can further comprise a steam conveying flow path. The steam conveying flow path can convey steam to the fluid output member 12. The steam can be steam formed by heating normal-temperature cleaning liquid, that is, steam can be water vapor and / or decontamination liquid steam, etc. The cleaning device 01 provided by the present disclosure can also have a steam cleaning mode, as shown by the dashed arrow in FIG. 1A, that is, when cleaning the surface to be cleaned, the steam conveying flow path can be used to convey steam to the fluid output member 12, and the steam can be used in cooperation with the cleaning working part 1 to clean, so as to improve the cleaning effect of the cleaning device 01. Figure 4 ​The line represented by the solid arrow in the figure shows that, when the surface to be cleaned is cleaned, steam can be delivered to the fluid output member 12 by the steam delivery flow path, and the steam is used to clean the cleaning working part 1. Since the steam has high temperature and humidity, the cleaning effect of the cleaning equipment 01 can be further improved.

[0128] The fluid output member 12 can be in communication with the steam delivery flow path to receive steam delivered by the steam delivery flow path. The fluid output member 12 can deliver steam to the cleaning member 13 to wet the cleaning member 13, which can further improve the cleaning ability of the cleaning member 13, thereby further improving the cleaning effect of the cleaning equipment 01. Alternatively, the fluid output member 12 can deliver steam to the surface to be cleaned in front of the cleaning member 13 to heat and wet the dirt on the surface to be cleaned in front of the cleaning member 13, so that the dirt on the surface to be cleaned is more easily cleaned by the cleaning member 13, thereby also achieving the purpose of further improving the cleaning effect of the cleaning equipment 01.

[0129] Alternatively, the cleaning equipment 01 can also have a self-cleaning mode. In the self-cleaning mode, the fluid output member 12 can deliver steam to the cleaning member 13 to wet the cleaning member 13, so as to self-clean the cleaning member 13 and improve the use convenience and service life of the cleaning equipment 01. In addition, the high-temperature steam can also sterilize and disinfect the cleaning member 13 to further improve the self-cleaning effect.

[0130] The fluid output member 12 can include a steam outlet 121, which can deliver steam to the cleaning member 13 or in front of the cleaning member 13. The fluid output member 12 can have one steam outlet 121 or a plurality of steam outlets 121 arranged at intervals. Steam can be delivered to the cleaning member 13 or in front of the cleaning member 13 through the plurality of steam outlets 121. In this way, the range of steam delivery by the fluid output member 12 can be improved, thereby further improving the cleaning effect or self-cleaning effect of the cleaning equipment 01. However, the fluid output member 12 can also not include a steam outlet 121. It can also be an independent structure that can deliver steam, or the fluid output member 12 can be an open end of a pipe of the steam delivery flow path, and the present disclosure does not limit this.

[0131] As can be seen from the above, the cleaning equipment 01 provided by the present disclosure can freely select the cleaning mode according to the cleaning needs, can improve the use range and cleaning effect of the cleaning equipment 01, and can also reasonably allocate the energy consumption of the cleaning equipment 01.

[0132] For example, when the dirt on the surface to be cleaned is not stubborn, only the cleaning member 13 can be used for cleaning, so that the cleaning equipment 01 can achieve good cleaning effect in a low-energy state.

[0133] When the dirt on the surface to be cleaned is relatively stubborn, the normal-temperature cleaning mode can be switched to, and the relatively stubborn dirt can be cleaned by the normal-temperature cleaning liquid cooperating with the cleaning piece 13, so that the cleaning equipment 01 realizes a better cleaning effect in a medium energy consumption state. And only when the dirt is relatively stubborn, the normal-temperature cleaning mode is switched to, which can reduce the time of the cleaning equipment 01 in the medium energy consumption state, so as to achieve the purpose of energy saving.

[0134] When the dirt on the surface to be cleaned is relatively stubborn, the normal-temperature cleaning mode can be switched to, and the relatively stubborn dirt can be cleaned by the normal-temperature cleaning liquid cooperating with the cleaning piece 13, so that the cleaning equipment 01 realizes a better cleaning effect in a medium energy consumption state. And only when the dirt is relatively stubborn, the normal-temperature cleaning mode is switched to, which can reduce the time of the cleaning equipment 01 in the medium energy consumption state, so as to achieve the purpose of energy saving.

[0135] The steam delivery flow path can access the normal-temperature cleaning liquid delivery flow path 2 to receive the normal-temperature cleaning liquid in the normal-temperature cleaning liquid delivery flow path 2, and heat the received normal-temperature cleaning liquid to form steam. The steam delivery flow path can access the normal-temperature cleaning liquid delivery flow path 2 at the first position of the normal-temperature cleaning liquid delivery flow path 2.

[0136] The steam delivery flow path can include a heater 5. The heater 5 can be a boiler, but is not limited to this, and the heater 5 can also be other components with heating capability. The input end of the heater 5 can access the normal-temperature cleaning liquid delivery flow path 2 for heating the cleaning liquid. When the steam delivery flow path accesses the normal-temperature cleaning liquid delivery flow path 2 at the first position of the normal-temperature cleaning liquid delivery flow path 2, the input end of the heater 5 can access the normal-temperature cleaning liquid delivery flow path 2 at the first position of the normal-temperature cleaning liquid delivery flow path 2. The output end of the heater 5 can be in communication with the fluid output piece 12 for delivering steam to the fluid output piece 12, but is not limited to this, and the heater 5 can also be other devices with heating function. In the normal-temperature cleaning mode, the heater 5 is in the closed state. In the steam cleaning mode, as shown by the solid arrow in the line in FIG. 5, the heater 5 is in the open state. Figure 4

[0137] ​The heater 5 can include a heater 5 body and a first filter screen. The first filter screen can be arranged in the heater 5 body and located between the input end and the output end of the heater 5 to filter the water in the heater 5 to avoid impurities blocking the pipeline and the cleaning work part 1, thereby improving the service life of the cleaning equipment 01. The mesh aperture of the first filter screen can be 1 mm to 3 mm, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. In this way, the first filter screen can have good filtering effect while improving the flow capacity of the first filter screen to ensure that the water in the heater 5 can pass through the first filter screen normally and reduce the probability of the first filter screen being blocked.

[0138] In some embodiments, the cleaning equipment 01 can further include a second filter screen 9, which can be arranged at the output end of the heater 5. The mesh aperture of the second filter screen 9 can be smaller than that of the first filter screen. In this way, the second filter screen 9 can be used to further filter the water or steam output from the heater 5 to further remove impurities inside, further reduce the probability of impurities blocking the downstream pipeline and the cleaning work part 1, and further improve the service life of the cleaning equipment 01.

[0139] The aperture of the second filter screen 9 can be 0.2 mm to 1 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. In this way, the second filter screen 9 can have good filtering effect and improve the flow capacity of the second filter screen 9 to ensure that the water in the heater 5 can pass through the second filter screen 9 normally.

[0140] The filtering area of the second filter screen 9 can be greater than that of the first filter screen to improve the filtering effect of the second filter screen 9 and ensure that the cleaning liquid or steam delivered to the downstream pipeline and the cleaning work part 1 is impurity-free. Moreover, by increasing the filtering area of the second filter screen 9, the probability of the second filter screen 9 being blocked can be reduced.

[0141] The filtering area of the second filter screen 9 can be 500 mm 2 to 2000 mm 2 , for example, 500 mm 2 , 600 mm 2 , 700 mm 2 , 800 mm 2 , 900 mm 2 , 1000 mm 2 , 1100 mm 2 , 1200 mm 2 , 1300 mm 2 , 1400 mm 2 , 1500 mm 21600mm 2 1700mm 2 1800mm 2 1900mm 2 2000mm 2 In this way, the second filter screen 9 has sufficient filtering area, and the problem of occupying a large internal space of the cleaning device 01 due to the large filtering area of the second filter screen 9 can be avoided, and the miniaturization of the cleaning device 01 can be facilitated.

[0142] The normal-temperature cleaning liquid conveying flow path 2 can include a liquid supply tank 21, which can be used to store the normal-temperature cleaning liquid and supply the normal-temperature cleaning liquid to the normal-temperature cleaning liquid conveying flow path 2.

[0143] The normal-temperature cleaning liquid conveying flow path 2 can include a first liquid pump 22. The first liquid pump 22 can be located on the normal-temperature cleaning liquid conveying flow path 2. The input end of the first liquid pump 22 can be in communication with the liquid supply tank 21 to extract the normal-temperature cleaning liquid in the liquid supply tank 21. The output end of the first liquid pump 22 can be used to convey the normal-temperature cleaning liquid to the distribution member 11.

[0144] The steam conveying flow path can include a second liquid pump 6. The second liquid pump 6 can be connected to the normal-temperature cleaning liquid conveying flow path 2 at a first position of the normal-temperature cleaning liquid conveying flow path 2. The input end of the second liquid pump 6 can be connected to the normal-temperature cleaning liquid conveying flow path 2 at the first position of the normal-temperature cleaning liquid conveying flow path 2, and the output end of the second liquid pump 6 can be in communication with the input end of the heater 5. By providing the second liquid pump 6, the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 can be pumped into the steam conveying flow path.

[0145] In the normal-temperature cleaning mode, as shown by the solid arrow in FIG. 1A, the first liquid pump 22 can be in an open state, the second liquid pump 6 can be in a closed state, and the normal-temperature cleaning liquid conveying flow path 2 can convey the normal-temperature cleaning liquid to the distribution member 11. Figure 3 In the steam cleaning mode, as shown by the solid arrow in FIG. 1B, the first liquid pump 22 and the second liquid pump 6 can both be in an open state, the normal-temperature cleaning liquid conveying flow path 2 can convey the normal-temperature cleaning liquid to the distribution member 11, and the steam conveying flow path can convey the steam to the fluid output member 12. Figure 4 In the steam cleaning mode, as shown by the solid arrow in FIG. 1B, the first liquid pump 22 and the second liquid pump 6 can both be in an open state, the normal-temperature cleaning liquid conveying flow path 2 can convey the normal-temperature cleaning liquid to the distribution member 11, and the steam conveying flow path can convey the steam to the fluid output member 12.

[0146] In some embodiments, the flow rate of the second liquid pump 6 can be less than that of the first liquid pump 22. Since a large amount of cleaning liquid is not required when the steam delivery flow path delivers steam, by the above arrangement, the amount of cleaning liquid for each flow path can be reasonably allocated, avoiding waste of cleaning liquid resources, and ensuring that the steam delivery flow path can form steam more quickly. Moreover, since the amount of cleaning liquid required for the steam cleaning mode and the normal temperature cleaning mode is quite different, by arranging the first liquid pump 22 and the second liquid pump 6 in the normal temperature cleaning liquid delivery flow path 2 and the steam delivery flow path respectively, the normal temperature cleaning liquid delivery flow path 2 and the steam delivery flow path can avoid sharing a liquid pump, and the problem of poor uniformity of the pump during mode switching can be avoided, to ensure the uniformity of steam or normal temperature cleaning liquid output. At the same time, by arranging the first liquid pump 22 and the second liquid pump 6, the uniformity of each liquid pump can be improved, and the probability of damage to each liquid pump can be reduced, to improve the use reliability and service life of the cleaning equipment 01.

[0147] The flow rate of the first liquid pump 22 can range from 10 ml / min to 500 ml / min, for example: 10 ml / min, 50 ml / min, 100 ml / min, 150 ml / min, 200 ml / min, 250 ml / min, 300 ml / min, 350 ml / min, 400 ml / min, 450 ml / min, 500 ml / min, etc. By such arrangement, the delivery amount of normal temperature cleaning liquid during the normal temperature cleaning mode can be ensured.

[0148] The flow rate of the second liquid pump 6 can range from 0.5 ml / min to 9 ml / min, for example: 0.5 ml / min, 1 ml / min, 2 ml / min, 3 ml / min, 4 ml / min, 5 ml / min, 6 ml / min, 7 ml / min, 8 ml / min, 9 ml / min, etc. By such arrangement, the amount of cleaning liquid required during the steam cleaning mode can be ensured. It can avoid the problem of slow and uneven steam formation caused by too much cleaning liquid during the steam cleaning mode. It can also avoid the problem of dry burning of the heater 5 caused by too little cleaning liquid during the steam cleaning mode, thereby avoiding damage to the heater 5. At the same time, it can also avoid the problem of too little steam formation caused by too little cleaning liquid, to ensure the cleaning effect of the cleaning equipment 01 during the steam cleaning mode.

[0149] The steam delivery flow path can comprise a pressure relief valve 7. The pressure relief valve 7 can have a second input end, an output end and a pressure relief end. The second input end of the pressure relief valve 7 can be in communication with the output end of the second liquid pump 6, the output end of the pressure relief valve 7 can be in communication with the input end of the heater 5, and the pressure relief end of the pressure relief valve 7 can be in communication with the outside of the cleaning device 01, so as to adjust the pressure in the steam delivery flow path and avoid damage to the steam delivery flow path due to excessive liquid pressure in the steam delivery flow path.

[0150] The pressure relief valve 7 can comprise a spring valve that automatically opens when the pressure in the pipeline of the cleaning device 01 is too high, and automatically closes when the pressure in the pipeline of the cleaning device 01 is normal. In this way, automatic adjustment of the pressure in the pipeline of the cleaning device 01 can be achieved.

[0151] The normal-temperature cleaning liquid delivery flow path 2 can further comprise a first reversing valve 25, which can be located at a third position of the normal-temperature cleaning liquid delivery flow path 2, and the third position can be located between the first liquid pump 22 and the distribution member 11. The pressure relief valve 7 can further have a first input end, the input end of the first reversing valve 25 can be in communication with the output end of the first liquid pump 22, the first output end of the first reversing valve 25 can be in communication with the first input end of the pressure relief valve 7, and the second output end of the first reversing valve 25 can be in communication with the distribution member 11. In this way, the normal-temperature cleaning liquid delivery flow path 2 can be in communication with the pressure relief valve 7, and the pressure in the normal-temperature cleaning liquid delivery flow path 2 can be adjusted by the pressure relief valve 7 to avoid damage to the normal-temperature cleaning liquid delivery flow path 2 due to excessive water pressure in the normal-temperature cleaning liquid delivery flow path 2.

[0152] The cleaning device 01 can further comprise a stain removal liquid delivery flow path 3. The stain removal liquid delivery flow path 3 can be used to deliver stain removal liquid to the normal-temperature cleaning liquid delivery flow path 2, i.e., the stain removal liquid delivery flow path 3 can access the normal-temperature cleaning liquid delivery flow path 2 to further improve the cleaning effect of the cleaning device 01 on the surface to be cleaned.

[0153] The stain removal liquid delivery flow path 3 can access the normal-temperature cleaning liquid delivery flow path 2 at a second position. That is, the second position can be located downstream of the first position, i.e., the first position can be located upstream of the second position, and the water in the normal-temperature cleaning liquid delivery flow path 2 passes through the first position first and then passes through the second position. Stain removal liquid is usually highly corrosive, and such an arrangement can avoid the situation where the stain removal liquid enters the heater 5 and causes the cleaning device 01 to malfunction, thereby improving the use reliability of the cleaning device 01 and improving the user's use experience.

[0154] The decontamination liquid conveying flow path 3 can include a decontamination liquid supply tank 31 and a third liquid pump 32. The decontamination liquid supply tank 31 can be used to store decontamination liquid. The input end of the third liquid pump 32 can be in communication with the decontamination liquid supply tank 31, and the output end of the third liquid pump 32 can be connected to the normal-temperature cleaning liquid conveying flow path 2. That is, the output end of the third liquid pump 32 can be connected to the normal-temperature cleaning liquid conveying flow path 2 at the second position. The third liquid pump 32 can draw out the decontamination liquid in the decontamination liquid supply tank 31 and convey it to the normal-temperature cleaning liquid conveying flow path 2.

[0155] In some embodiments, the decontamination liquid supply tank 31 can be located in the liquid supply tank 21 to improve the integration of the cleaning device 01. The decontamination liquid addition port of the decontamination liquid supply tank 31 and the normal-temperature cleaning liquid addition port of the liquid supply tank 21 can be different addition ports to facilitate the addition of decontamination liquid and normal-temperature cleaning liquid, respectively.

[0156] The normal-temperature cleaning liquid conveying flow path 2 can further include a first multi-pass 23. The first multi-pass 23 can be located at the first position of the normal-temperature cleaning liquid conveying flow path 2, and the first multi-pass 23 can have multiple ports. The steam conveying flow path can pass through the first multi-pass 23 to connect to the normal-temperature cleaning liquid conveying flow path 2, and specifically, the input end of the heater 5 can pass through the first multi-pass 23 to connect to the normal-temperature cleaning liquid conveying flow path 2. That is, it can be understood that the pipeline between the starting end of the normal-temperature cleaning liquid conveying flow path 2 and the first position can be reused as part of the steam conveying flow path to convey normal-temperature cleaning liquid to the input end of the heater.

[0157] Further, the liquid supply tank 21, the input end of the first liquid pump 22, and the input end of the second liquid pump 6 can be in communication with different ports of the first multi-pass 23, respectively, to divert part of the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 to the steam conveying flow path through the first multi-pass 23. In this embodiment, the first multi-pass 23 can be a three-way pass, that is, the first multi-pass 23 can have three ports, but is not limited thereto, and the first multi-pass 23 can have more than three ports.

[0158] The first multi-pass 23 to the first liquid pump 22 can have a first flow resistance, and the first multi-pass 23 to the second liquid pump 6 can have a second flow resistance. The first flow resistance can be greater than the second flow resistance, so that the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 can be prevented from being excessively conveyed to the first liquid pump 22, that is, the normal-temperature cleaning liquid can be prevented from being excessively occupied by the first liquid pump 22 with a larger flow rate, to ensure that the second liquid pump 6 can also obtain sufficient normal-temperature cleaning liquid, and to ensure that the steam conveying flow path can obtain sufficient normal-temperature cleaning liquid for forming steam in the steam cleaning mode.

[0159] The pipeline between the first multi-pass 23 and the first liquid pump 22 can have a first length, and the pipeline between the second multi-pass 24 and the second liquid pump 6 can have a second length, which can be less than the first length. In this way, the first flow resistance between the first multi-pass 23 and the first liquid pump 22 can be increased, so that the first flow resistance is greater than the second flow resistance.

[0160] The pipeline between the first multi-pass 23 and the first liquid pump 22 can have a first cross-sectional area, and the pipeline between the first multi-pass 23 and the second liquid pump 6 can have a second cross-sectional area, which can be greater than the first cross-sectional area. In this way, the first liquid pump 22 with a larger flow rate can also be prevented from occupying too much of the normal-temperature cleaning liquid, so that the second liquid pump 6 can also obtain sufficient normal-temperature cleaning liquid.

[0161] A first number of components can be arranged on the pipeline between the first multi-pass 23 and the first liquid pump 22. A second number of components can be arranged on the pipeline between the second multi-pass 24 and the second liquid pump 6. The second number can be less than the first number. In this way, the water can pass through more components on the way from the first multi-pass 23 to the first liquid pump 22, so that the first flow resistance can be increased, and the first flow resistance is greater than the second flow resistance.

[0162] It should be noted that the components described herein can include multi-passes, valve bodies, liquid pumps, and other components with water flow capacity.

[0163] The normal-temperature cleaning liquid delivery flow path 2 can further include a second multi-pass 24. The second multi-pass 24 can be located at a second position of the normal-temperature cleaning liquid delivery flow path 2, i.e., the second multi-pass 24 can be located on the pipeline between the first multi-pass 23 and the first liquid pump 22. Moreover, the second multi-pass 24 can have a plurality of ports, and the stain removal liquid delivery flow path 3 can access the normal-temperature cleaning liquid delivery flow path 2 through the second multi-pass 24 to deliver the cleaning liquid in the cleaning delivery flow path to the normal-temperature cleaning liquid delivery flow path 2. Further, the input end of the first liquid pump 22 and the output end of the third liquid pump 32 can be respectively communicated with different ports of the second multi-pass 24. In this embodiment, the second multi-pass 24 can be a three-way, i.e., the second multi-pass 24 can have three ports, but is not limited thereto, and the second multi-pass 24 can have more than four ports.

[0164] In other embodiments, the stain removal liquid delivery flow path 3 also accesses the normal-temperature cleaning liquid delivery flow path 2 through the first multi-pass 23. That is, the output end of the third liquid pump 32 can be communicated with a port of the first multi-pass 23. In this way, only one multi-pass can be arranged in the cleaning device 01, which can reduce the manufacturing cost of the cleaning device 01 and save the internal space of the cleaning device 01. In this embodiment, the first multi-pass 23 can be a four-way, i.e., the first multi-pass 23 can have four ports, but is not limited thereto, and the first multi-pass 23 can have more than four ports.

[0165] In some embodiments, the cleaning device 01 can further comprise a hot cleaning liquid delivery flow path. The hot cleaning liquid delivery flow path can be used to deliver hot cleaning liquid to the distribution member 11. The cleaning device 01 can have a heating cleaning mode, as shown by the solid arrow in the line in FIG. 1, that is, when cleaning the surface to be cleaned, the hot cleaning liquid delivery flow path can be used to deliver hot cleaning liquid to the distribution member 11, and the cleaning work part 1 can be cleaned with the hot cleaning liquid. Because the hot cleaning liquid has a high temperature and humidity, the cleaning effect of the cleaning device 01 can be further improved compared with the normal temperature cleaning mode. Figure 5

[0166] When the dirt on the surface to be cleaned is relatively stubborn, the heating cleaning mode can be switched to, and the hot cleaning liquid can be used to clean the relatively stubborn dirt together with the cleaning member 13, so that the cleaning device 01 can achieve a better cleaning effect in a medium or high energy consumption state. And only when the dirt is relatively stubborn, the heating cleaning mode is switched to, so that the time of the cleaning device 01 in the medium or high energy consumption state can be reduced, so as to achieve the purpose of energy saving.

[0167] The pipeline between the starting end of the normal temperature cleaning liquid delivery flow path 2 and the third position can be reused as part of the pipeline of the hot cleaning liquid delivery flow path, and be used to deliver normal temperature cleaning liquid to the input end of the heater 5. The third position can be located between the first liquid pump 22 and the distribution member 11. It can be understood that the water entering the hot cleaning liquid delivery flow path does not pass through the second liquid pump 6. And when the cleaning device 01 has the dirt removal liquid delivery flow path 3, the third position can be located downstream of the access position of the dirt removal liquid delivery flow path 3, so that the dirt removal liquid can enter the hot cleaning liquid delivery flow path, and the cleaning effect of the heating cleaning mode can be improved. In the heating cleaning mode, the first liquid pump 22 can be in an open state, the second liquid pump 6 can be in a closed state, and the dirt removal liquid delivery flow path 3 can deliver dirt removal liquid to the hot cleaning liquid delivery flow path.

[0168] The hot cleaning liquid delivery flow path can comprise the above-mentioned heater 5, that is, the hot cleaning liquid delivery flow path and the steam delivery flow path can share one heater 5, so as to reduce the number of heaters 5, improve the integration of the cleaning device 01, and reduce the manufacturing cost of the cleaning device 01. In the heating cleaning mode, the heater 5 can be turned on.

[0169] ​The normal-temperature cleaning liquid delivery flow path 2 can further include a first reversing valve 25. The first reversing valve 25 can be located at a third position, an input end of the first reversing valve 25 can be in communication with an output end of the first liquid pump 22, a first output end of the first reversing valve 25 can be in communication with an input end of the heater 5, and a second output end of the first reversing valve 25 can be in communication with the dispensing member 11. In the heating cleaning mode, the first reversing valve 25 can be in communication with the input end of the heater 5, so that the normal-temperature cleaning liquid delivery flow path 2 delivers the normal-temperature cleaning liquid to the heater 5 through the third position. In the normal-temperature cleaning mode, the first reversing valve 25 can be in communication with the dispensing member 11, so that the normal-temperature cleaning liquid delivery flow path 2 directly delivers the normal-temperature cleaning liquid to the dispensing member 11.

[0170] The output end of the heater 5 can be connected to the normal-temperature cleaning liquid delivery flow path 2 at a fourth position of the normal-temperature cleaning liquid delivery flow path 2, that is, a pipeline between the fourth position and the end of the normal-temperature cleaning liquid delivery flow path 2 can be reused as part of the hot cleaning liquid delivery flow path for delivering the hot cleaning liquid heated by the heater 5 to the dispensing member 11. The fourth position can be located between the third position and the dispensing member 11, so that the water heated by the heater 5 is delivered to the dispensing member 11 through the fourth position via the normal-temperature cleaning liquid delivery flow path 2, and the hot cleaning liquid is delivered to the cleaning member 13 or in front of the cleaning member 13 via the dispensing member 11.

[0171] The normal-temperature cleaning liquid delivery flow path 2 can further include a third multi-way valve 26. The third multi-way valve 26 can be located at the fourth position, and the third multi-way valve 26 can have multiple ports. The second output end of the first reversing valve 25, the output end of the heater 5, and the dispensing member 11 can be in communication with different ports of the third multi-way valve 26, respectively. By providing the third multi-way valve 26, the normal-temperature cleaning liquid delivery flow path 2 and the hot cleaning liquid delivery flow path can be integrated, so that in the normal-temperature cleaning mode, the normal-temperature cleaning liquid can be directly delivered to the dispensing member 11 via the third multi-way valve 26, and in the heating cleaning mode, the normal-temperature cleaning liquid can be heated by the heater 5 and delivered to the dispensing member 11 via the third multi-way valve 26. In this embodiment, the third multi-way valve 26 can be a three-way valve, that is, the third multi-way valve 26 can have three ports, but is not limited thereto, and the third multi-way valve 26 can have multiple ports.

[0172] The hot cleaning fluid delivery path may further include a fourth multi-port 8. The fourth multi-port 8 may have multiple ports, and the output end of the second liquid pump 6, the first output end of the first reversing valve 25, and the input end of the heater 5 can be connected to different ports of the fourth multi-port 8 respectively. By setting the fourth multi-port 8, the steam cleaning path and the hot cleaning fluid delivery path can be integrated, so that in steam cleaning mode and self-cleaning mode, room temperature cleaning fluid can enter the heater 5 through the second liquid pump 6 and the fourth multi-port 8; in heating cleaning mode, room temperature cleaning fluid can directly enter the heater 5 through the first reversing valve 25 and the fourth multi-port 8. In this embodiment, the fourth multi-port 8 can be a three-way valve, that is, the fourth multi-port 8 can have three ports, but it is not limited to this; the fourth multi-port 8 can also have multiple ports.

[0173] Furthermore, the first output terminal of the first reversing valve 25 can be connected to the first output terminal of the pressure relief valve 7, so as to deliver room temperature cleaning fluid to the pressure relief valve 7 when the pressure of the room temperature cleaning fluid delivery path 2 is too high, thereby regulating the pressure of the room temperature cleaning fluid delivery path 2. Also, with this configuration, room temperature cleaning fluid can be delivered to the heater 5 through the first pressure relief valve 7.

[0174] In some embodiments, the fourth multi-port valve 8 can be reused as a pressure relief valve 7, that is, the valve body can integrate the functions of the fourth multi-port valve 8 and the pressure relief valve 7. This configuration saves on manufacturing molds and reduces the manufacturing cost of the cleaning equipment 01. Furthermore, it reduces the number of parts in the cleaning equipment 01, saving internal space.

[0175] In some embodiments, the cleaning device 01 may further include a descaling and cleaning flow path 4. The descaling and cleaning flow path 4 may include the heater 5 described above. That is, the descaling and cleaning flow path 4 may share the heater 5 with the steam delivery flow path and / or the hot cleaning liquid delivery flow path. The descaling and cleaning flow path 4 may further include a second reversing valve 10. The input end of the second reversing valve 10 may be connected to the heater 5, the first output end of the second reversing valve 10 may be connected to the fluid output component 12, and the second output end of the second reversing valve 10 may be connected to the outside of the cleaning device 01.

[0176] Cleaning equipment 01 can also have a descaling cleaning mode, such as Figure 6 and Figure 7 As shown by the solid arrow in the diagram, in the descaling and cleaning mode, the second reversing valve 10 can be connected to the outside of the cleaning device 01 to discharge scale to the outside of the cleaning device 01 via the second reversing valve 10.

[0177] In some embodiments, the heater 5 can be in the off state when in the descaling cleaning mode. A descaling agent can be added into the descaling cleaning flow path 4 so as to enter the heater 5 to descale the heater 5, and the descaled descaling agent and / or scale can be discharged to the outside of the cleaning apparatus 01 via the second reversing valve 10. Further, by discharging the descaled descaling agent to the outside of the cleaning apparatus 01 via the second reversing valve 10, the descaled descaling agent can be prevented from entering the fluid output 12 to block the fluid output 12.

[0178] The descaling cleaning flow path 4 can be communicated with the first liquid pump 22, i.e., the descaling cleaning flow path 4 and the normal-temperature cleaning liquid delivery flow path 2 can share the first liquid pump 22. In this way, the descaling agent can be delivered by the first liquid pump 22, the first liquid pump 22 can also be descaled and maintained, and the descaling effect of the descaling agent on the first liquid pump 22 and the heater 5 can be improved.

[0179] In the descaling cleaning mode, the descaling agent can be added into the descaling cleaning flow path 4, the first liquid pump 22 can be in the on state, the second liquid pump 6 and the heater 5 can be in the off state, the first reversing valve 25 can be communicated with the heater 5, and the second reversing valve 10 can be communicated with the outside of the cleaning apparatus 01 so as to make the descaling agent enter the heater 5.

[0180] In the steam cleaning mode, the second reversing valve 10 can be communicated with the fluid output 12 so as to deliver steam to the fluid output 12. In the heated cleaning mode, the second reversing valve 10 can be communicated with the dispensing member 11 so as to deliver heated cleaning liquid to the dispensing member 11.

[0181] In some embodiments, the descaled descaling agent can be discharged to the cleaning member 13 via the second reversing valve 10. Further, the second output end of the second reversing valve 10 can be communicated with the dispensing member 11, the descaled descaling agent can be delivered to the dispensing member 11 via the second reversing valve 10, and delivered to the outside of the cleaning apparatus 01 by the dispensing member 11. For example, the descaled descaling agent can be delivered to the dispensing member 11 via the second reversing valve 10, and delivered to the cleaning member 13 by the dispensing member 11.

[0182] In some embodiments, the pipeline from the starting end of the ambient temperature cleaning fluid delivery path 2 to the fifth position can be reused as part of the descaling cleaning path for delivering the descaling agent to the heater 5. That is, the input end of the heater 5 can be connected to the ambient temperature cleaning fluid delivery path 2 at the fifth position. The first reversing valve 25 can be located at the fifth position, and the input end of the heater 5 can be connected to the first output end of the first reversing valve 25. The fifth position can be located between the first liquid pump 22 and the distributor 11, so that the descaling agent after descaling is delivered to the distributor 11 via the ambient temperature cleaning fluid delivery path 2 through the fifth position, and then delivered to the cleaning component 13 or to the front of the cleaning component 13 through the distributor 11, thereby discharging the descaling agent after descaling to the outside of the cleaning equipment 01.

[0183] The fifth and third positions can be the same, and the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path can be the same. That is, the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path can share all components. This arrangement can improve the integration and consolidation of the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path, further improving the integration of the cleaning equipment 01 and reducing the number of redundant components.

[0184] In this embodiment, the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can share the second reversing valve 10. The second input end of the second reversing valve 10 can be connected to the fourth multi-port 8 to deliver the hot cleaning liquid or the descaling agent after descaling to the distribution component 11 through the fourth multi-port 8.

[0185] In some embodiments, the descaling agent can be manually added to the descaling and cleaning flow path 4. Further, the descaling agent can be manually added to the supply tank 21 and then delivered to the descaling and cleaning flow path via the ambient temperature cleaning fluid delivery flow path 2.

[0186] In other embodiments, such as Figure 2 and Figure 7 As shown, the descaling and cleaning flow path 4 may include: a descaling agent supply chamber 41 and a fourth liquid pump 42. The descaling agent supply chamber 41 can be used to store descaling agent. The input end of the fourth liquid pump 42 can be connected to the descaling agent supply chamber 41, and the output end of the fourth liquid pump 42 can be connected to the heater 5.

[0187] In some embodiments, the descaling agent supply chamber 41 may be located inside the liquid supply tank 21 to improve the integration of the cleaning device 01. The descaling agent inlet, the cleaning agent inlet, and the room temperature cleaning liquid inlet of the liquid supply tank 21 may be different inlets to facilitate the addition of cleaning solution and room temperature cleaning solution respectively.

[0188] In some embodiments, the heater 5 can be used to heat the cleaning liquid and deliver the hot cleaning liquid to the fluid output member 12, so that the hot cleaning liquid is delivered to the front of the cleaning member 13 through the fluid output member 12 to clean the surface in cooperation with the cleaning member 13, thereby improving the cleaning effect of the cleaning device 01. The cleaning device 01 can have a strong cleaning mode, such as Figure 7 In the strong cleaning mode, the hot cleaning liquid can be delivered to the surface to be cleaned through the fluid output member 12 for cleaning heavy oil stains or dirt with high strength and stubbornness, as indicated by the solid arrow in the line. In the strong cleaning mode, the heater 5 can be turned on to heat the cleaning liquid and deliver the hot cleaning liquid to the fluid output member 12, so that the hot cleaning liquid is delivered to the front of the cleaning member 13 through the fluid output member 12.

[0189] When the dirt on the surface to be cleaned has heavy oil stains or dirt with high strength and stubbornness, the strong cleaning mode can be switched to, so that the cleaning device 01 can achieve better cleaning effect in a high energy consumption state. And only when the dirt has heavy oil stains or dirt with high strength and stubbornness, the strong cleaning mode is switched to, which can reduce the time of the cleaning device 01 in the high energy consumption state, so as to achieve the purpose of energy saving.

[0190] In some embodiments, the cleaning device 01 can include a strong cleaning flow path. The strong cleaning flow path can include a third heat exchange valve and a heater 5.

The sixth position can be located between the first liquid pump 22 and the distribution member 11. It can be understood that the water entering the strong cleaning flow path does not pass through the second liquid pump 6. Moreover, when the cleaning device 01 has the stain-removing liquid delivery flow path 3, the sixth position can be located downstream of the access position of the stain-removing liquid delivery flow path 3, so that the stain-removing liquid can enter the strong cleaning flow path, improving the cleaning effect of the strong cleaning mode. In the strong cleaning mode, the first liquid pump 22 can be in an open state, the second liquid pump 6 can be in a closed state, and the stain-removing liquid delivery flow path 3 can deliver stain-removing liquid to the strong cleaning flow path.

[0195] In some embodiments, the cleaning device 01 can further include a self-cleaning flow path. The self-cleaning flow path can include the above-mentioned second liquid pump 6 and the heater 5. In the self-cleaning mode, as shown by the solid arrow in the line in FIG. 1, the second liquid pump 6 and the heater 5 are in an open state to heat the cleaning liquid to generate steam and deliver the steam to the distribution member 11. In this way, the self-cleaning flow path and the steam cleaning flow path can be integrated and integrated, further improving the integration of the cleaning device 01, and reducing the setting of redundant components.

[0198] In some embodiments, the third position, the fifth position, and the sixth position described above can all be the same, and the second directional valve 10, the third directional valve 14, and the fourth directional valve 15 can all be the same, but are not limited thereto.

[0199] In some embodiments, as shown in Figures 1 to 9 The flow detector 27 can be a flow sensor or the like. The flow detector 27 can be located between the liquid supply tank 21 and the first position for detecting the amount of water entering the normal-temperature cleaning liquid delivery flow path 2 from the liquid supply tank 21. In addition, by detecting whether there is water in the normal-temperature cleaning liquid delivery flow path 2, it can be determined whether to turn on the heater 5 to prevent the heater 5 from being dry-burned without water and reduce the probability of damage to the heater 5.

[0200] In some embodiments, a preset time can be set, and the heater 5 can be turned on only when the flow detector 27 detects that there is water in the normal-temperature cleaning liquid delivery flow path 2 within the preset time. The preset time can be 3 seconds, but is not limited thereto.
